There have been many other proposed predisposing factors to injury. These include muscle weakness, muscle imbalance, poor flexibility, fatigue, inadequate warm up, poor neuromuscular control, and poor running technique. One of the few predisposing factors that most researchers agree upon however is previous hamstring injury. Brokett et al. (2004) stated that “the athletes most at risk of a hamstring strain are those with a previous history of such injury” and noted that 34% of the hamstring injuries were recurrences.” Cameron et al.
The Andersen healthcare utilization model is a conceptual model aimed at demonstrating the factors that lead to the use of health services. According to the model, usage of health services (including inpatient care, physician visits, dental care etc.) is determined by three dynamics: predisposing factors, enabling factors, and need. Predisposing factors can be characteristics such as race, age, and health beliefs. For instance, an individual who believes health services are an effective treatment for an ailment is more likely to seek care.
Delirium arises through the interaction of a number of predisposing and precipitating factors. Individuals with multiple and/or significant predisposing factors are highly at risk for suffering an episode of delirium with a single and/or mild precipitating factor. Conversely, delirium may only result in healthy individuals if they suffer serious or multiple precipitating factors. It is important to note that the factors affecting those of an individual can change over time, thus an individual’s risk of delirium is dynamic.
Macrolide antibiotics, including erythromycin, are associated with reversible ototoxic effects. The underlying mechanism of ototoxicity may be impairment of ion transport in the stria vascularis. Predisposing factors include renal impairment, hepatic impairment, and recent organ transplantation.

Sural mononeuropathy is uncommon. If affected, it can be due to a mass lesion such as a ganglion or to trauma, which is the most common cause.Stickler DE, Morley KN, Massey EW. Sural neuropathy: etiologies and predisposing factors. Muscle Nerve.
Smoking, especially heavy smoking, is an important predisposing factor but the reasons for this relationship are unknown. One hypothesis is that cigarette smoke contains nutritional factors for C. albicans, or that local epithelial alterations occur that facilitate colonization of candida species.
Sometimes white patches are too large to remove completely and instead they are monitored closely. Even if the lesion is completely removed, long term review is still usually indicated since leukoplakia can recur, especially if predisposing factors such as smoking are not stopped.
The patient may develop neutralizing antibodies reducing the effectiveness of muromonab-CD3. Muromonab-CD3 can cause excessive immunosuppression. Although CD3 antibodies act more specifically than polyclonal antibodies, they lower the cell-mediated immunity significantly, predisposing the patient to opportunistic infections and malignancies.
Predisposing factors include abnormal amount of subcutaneous fat, thick ankles and abnormally poor arterial supply. Abnormal arterial supply causes low-grade ischemia of ankle region. The ankle skin becomes sensitive to temperature changes. When weather is cold, ankle is cold, blue and often tender.
Risk factors predisposing to the development of a PAA include: tobacco smoking, atherosclerosis, connective tissue disorders (e.g. Marfan syndrome, and Ehler-Danlos syndrome), advanced age (peaking in the 6th to 7th decade of life), male gender, White race, and a family history of aneurysm.
Examples would be moderate constant checking of hygiene, the hearth or the environment for enemies. Similarly, hoarding may have had evolutionary advantages. In this view OCD may be the extreme statistical "tail" of such behaviors, possibly due to a high amount of predisposing genes.
Condition predisposing to anaerobic infections include: exposure of a sterile body location to a high inoculum of indigenous bacteria of mucous membrane flora origin, inadequate blood supply and tissue necrosis which lower the oxidation and reduction potential which support the growth of anaerobes. Conditions which can lower the blood supply and can predispose to anaerobic infection are: trauma, foreign body, malignancy, surgery, edema, shock, colitis and vascular disease. Other predisposing conditions include splenectomy, neutropenia, immunosuppression, hypogammaglobinemia, leukemia, collagen vascular disease and cytotoxic drugs and diabetes mellitus. A preexisting infection caused by aerobic or facultative organisms can alter the local tissue conditions and make them more favorable for the growth of anaerobes.
Cases of MBA associated with EBV+ LPD have been reported most often in Japan, Taiwan, Korea, and the native populations of Mexico, Central America, and South America. This reaction occurs primarily in younger individuals (0–18 years old; mean age 6.7 years) who have evidence of one of the predisposing EBV+ LPD. Rarely, however, it occurs in individuals who exhibit no signs or symptoms of a predisposing disorder but later develop CAEBV. In addition to the signs and symptoms of their specific EBV+ LPD (see Epstein-Barr virus- associated lymphoproliferative diseases), these individuals are subject to severe local as well as systemic reactions to mosquito bites.
There are long- term, biological, environmental, and social causes of panic attacks. In 1993, Fava et al. proposed a staging method of understanding the origins of disorders. The first stage in developing a disorder involves predisposing factors, such as genetics, personality, and a lack of wellbeing.
Muscle weakness has also been an implication as a predisposing factor for both primary and recurring hamstring strain injuries.Kuske B, Hamilton DF, Pattle SB, Simpson AHRW (2016) Patterns of Hamstring Muscle Tears in the General Population: A Systematic Review. PLoS ONE 11(5):e0152855.doi:10.1371/journal.pone.
Personal Interview. 24 Oct. 2011. These tumors, papillary tumors in this case, have no known predisposing genetic characteristics, as stated by Dr. Janss when I interviewed her. She said that there is nothing that links the likelihood of getting this tumor type to genetics, meaning nothing is inherited.
One potential change for a future iteration of this model is to add genetic information under predisposing characteristics. As genetic information becomes more readily available it seems likely this could impact health services usage, as well as health outcomes, beyond what is already accounted for in the current model.
Microbiol Mol Biol Rev 69, 426-439 (2005). In this type of a screen, the genetic or environmental background is modified so as to sensitize the mouse to these changes. The idea is that the predisposing genes can be unraveled on a modified genetic or environmental background. Rinchik et al.
Inappropriate information hierarchy may impede the prescription understanding by patients. A study unveiled that 33% of medication errors was induced by ambiguous labelling. This may lead to medication errors in drug prescribing, dispensing or administration, particularly in geriatric, illiterate, visually impaired or cognitively impaired population, predisposing them to non-adherence.
Anaphylaxis typically begins over a few minutes in a person with a previous history of the same. Other symptoms include urticaria, throat swelling, and gastrointestinal upset. The primary treatment is epinephrine. Interstitial lung disease presents with gradual onset of shortness of breath typically with a history of a predisposing environmental exposure.
Yeast infection. Vaginal yeast infections are typically caused by the yeast species Candida albicans. Candida albicans is a common fungus often harbored in the mouth, digestive tract, or vagina without causing adverse symptoms. The causes of excessive Candida growth are not well understood, but some predisposing factors have been identified.
Fungal growth is most common during milk, dough and dent stages. Diplodia stalk rot takes place mainly in the crown, mesocotyl, roots, and less frequently on the nodes between the crown and the ear. For both diseases, points of entry are facilitated by pest (e.g. bird, insect) damage, predisposing the host.
Major risk factors include smoking, lack of oral hygiene with inadequate plaque biofilm control. There is a slow to moderate rate of disease progression but the patient may have periods of rapid progression ("bursts of destruction"). Chronic periodontitis can be associated with local predisposing factors (e.g. tooth-related or iatrogenic factors).
The presence of environmental triggers, such as viral infections, immunizations, and stress, and interactions with other genes contribute to the development of the white dot syndromes. Additionally, Jampol and Becker hypothesize that the predisposing genetic loci can be identified. Gass points to a lack of evidence in support of the Becker theory.
Predisposing factors include psychological stress, sleep deprivation, poor oral hygiene, smoking, immunosuppression and/or malnutrition. Necrotizing ulcerative periodontitis (NUP) is where the infection leads to attachment loss, and involves only the gingiva, periodontal ligament and alveolar ligament. Progression of the disease into tissue beyond the mucogingival junction characterizises necrotizing stomatitis (cancrum oris).
Seth Farber, "Homelessness, Madness, the Power Elites and Final Battles of the East Village," in Clayton Patterson, ed., Resistance: A Radical Social and Political History of the Lower East Side (2007). The Community Mental Health Act of 1963 was a predisposing factor in setting the stage for homelessness in the United States.
Some predisposing factors are known but their predictive value is minimal. It appears that proper breastfeeding technique, frequent breastfeeding and avoidance of stress are the most important factors that can be influenced. Light cases of mastitis are often called breast engorgement; the distinction is overlapping and possibly arbitrary or subject to regional variations.
Wound myiasis occurs when fly larvae infest open wounds. It has been a serious complication of war wounds in tropical areas, and is sometimes seen in neglected wounds in most parts of the world. Predisposing factors include poor socioeconomic conditions, extremes of age, neglect, mental disability, psychiatric illness, alcoholism, diabetes, and vascular occlusive disease.
In the case of genetic diseases involving multiple genes, mutations in multiple genes contributes to the progression of a disease. Mutation in just one of these genes however, might not contribute significantly to any phenotype. Such "predisposing genes" can be identified using sensitized screens.Cordes, S.P. N-ethyl-N-nitrosourea mutagenesis: boarding the mouse mutant express.
A precipitating cause is an immediate trigger that instigates a person's action or behavior. A predisposing cause is an underlying factor that interacts with the immediate factors to result in a disorder. Both causes play a key role in the development of a psychological disorder. For example, high neuroticism antedates most types of psychopathology.
Factors contributing to this include higher prevalence of predisposing health conditions and behaviours, and overcrowding and poverty. In some Canadian aboriginal groups, genetic susceptibility may play a role. Socioeconomic status (SES) strongly affects TB risk. People of low SES are both more likely to contract TB and to be more severely affected by the disease.
AML is commonly seen in pediatric patients with higher pediatric incidence in Hispanics and Asians as compared to non-Hispanic Caucasian and African Americans in the USA. Predisposition to AML includes but not limited to:Down syndrome, Klinefelter's syndrome, and Fanconi's anemia. Acquired predisposing factors include:Aplastic anemia, Chemotherapy, prenatal exposure to tobacco, marihuana, and alcohol.
Smoking may have a genetic predisposing factor; one 1990 study posited that 52% of the variance in smoking behaviour is attributable to heritable factors. The concept received support from a large-scale genetic analysis of 2016 that showed a genetic basis for the connection of the prevalence of cigarette smoking and cannabis use during the life of a person.
The reported incidence of constriction ring syndrome varies from 1/1200 and 1/15000 live births. The prevalence is equally in male and female. Fetomaternal factors like prematurity, maternal illness, low birth weight and maternal drug exposure are predisposing factors for the constriction ring syndrome. No positive relationship between CRS and genetic inheritance has been reported.
Esophageal candidiasis is an opportunistic infection of the esophagus by Candida albicans. The disease usually occurs in patients in immunocompromised states, including post-chemotherapy and in AIDS. However, it can also occur in patients with no predisposing risk factors, and is more likely to be asymptomatic in those patients. It is also known as candidal esophagitis or monilial esophagitis.
Predisposing factors include smoking, denture wearing, use of corticosteroid sprays or inhalers and human immunodeficiency virus (HIV) infection. Candida species even in healthy people mainly colonizes the posterior dorsal tongue. Median rhomboid glossitis is thought to be a type of chronic atrophic (or erythematous) candidiasis. Microbiological culture of the lesion usually shows Candida mixed with bacteria.
Its rupture during vaginal birth leads to widening of the gap between the anterior free borders of levator ani muscle of both sides, thus predisposing the woman to prolapse of the uterus, rectum, or even the urinary bladder. At this point, the following muscles converge and are attached: 1\. External anal sphincter 2\. Bulbospongiosus muscle 3\.
This is similar to PKD, characterizing as an episodic movement disorder, but is not triggered by voluntary movements. The attacks for PNKD are spontaneous and last from hours to days. It is an autosomal dominant disorder passing to nearly 50% of the offspring. Some predisposing factors include stress, excitement, alcoholic beverages, tea, and beverages with caffeine.
Diagnosis of IIA is based on finding an intracranial aneurysm on vascular imaging in the presence of predisposing infectious conditions. Positive bacterial cultures from blood or the infected aneurysm wall itself may confirm the diagnosis, however blood cultures are often negative. Other supporting findings include leukocytosis, an elevated erythrocyte sedimentation rate and elevated C-reactive protein in blood.
Pre-eclampsia affects approximately 2–8% of all pregnancies worldwide,World Health Organization (WHO). World health report 2005: make every mother and child count. Geneva: WHO; 2005, p. 63 The incidence of pre-eclampsia has risen in the U.S. since the 1990s, possibly as a result of increased prevalence of predisposing disorders, such as chronic hypertension, diabetes, and obesity.
In most cases of adult onset Tinea capitis due to M. audouinii, there is at least one predisposing factor such as immunocompromise (e.g., diabetes mellitus, systemic lupus, organ transplant and HIV), a local animal reservoir (e.g., infected pet or farm animal) and hormonal changes in postmenopausal women. Tinea capitis is seen in tropical, rural and suburban regions.
Not everyone is a good candidate for TRT. Factors associated with suitability for TRT and predisposing for favorable outcome are: lower loudness of tinnitus, higher pitch of tinnitus, shorter duration of tinnitus since onset, recognition of tinnitus attenuation by sound generator, lower hearing thresholds (i.e. better hearing), high Tinnitus Handicap Inventory (THI) score, and positive attitude toward therapy.
Candida-associated lesions are primary oral candidiases (confined to the mouth), where the causes are thought to be multiple. For example, bacteria as well as Candida species may be involved in these lesions. Frequently, antifungal therapy alone does not permanently resolve these lesions, but rather the underlying predisposing factors must be addressed, in addition to treating the candidiasis.
They were found in heterozygotes, suggesting an autosomal dominant inheritance pattern. However, based on other research and observations, these mutations seem to have an incomplete penetrance and some degree of codominance. It has a prevalence of 1.0–2.5% in people with body mass indices greater than 30, making it the most commonly known genetic defect predisposing people to obesity.
Patient characteristics and predisposing factors for thrombophlebitis nearly mirror those for DVT; thrombophlebitis is a risk factor for the development of DVT, and vice versa. Lower extremity superficial phlebitis is associated with conditions that increase the risk of thrombosis, including abnormalities of coagulation or fibrinolysis, endothelial dysfunction, infection, venous stasis, intravenous therapy and intravenous drug abuse.
SUFU encodes a component of the sonic hedgehog (SHH) / patched (PTCH) signaling pathway. Mutations in genes encoding components of this pathway are deleterious for normal development and are associated with cancer-predisposing syndromes (e.g., holoprosencephaly, HPE3, basal cell nevus syndrome, BCNS, and Greig cephalopolysyndactyly syndrome, GCPS).Sufu has also been found to have a crucial role in tumour suppression.
Sufferers experience very fragile skin, with blisters and skin erosion occurring in response to relatively benign trauma. Blisters may form all over the body, including the mucous membranes. Chronic scarring can lead to the formation of granulation tissue, which may bleed easily, predisposing to infection. Hands and fingers may be affected, as well as various joints.
A nasogastric tube may be necessary to continue feeding while treatment for the tumor is given, and some patients require a gastrostomy (feeding hole in the skin that gives direct access to the stomach). The latter two are especially important if the patient tends to aspirate food or saliva into the airways, predisposing for aspiration pneumonia.
Several risk factors of CMC OA of the thumb are known. Each of these risk factors does not cause CMC OA by itself, but acts as a predisposing factor influencing the process of OA in some way. Risk factors include: female gender, suffering from obesity, repetitive heavy manual labor, familial predisposition and hormonal changes, such as menopause.Tomaino, M. M. Thumb basal joint arthritis.
In extreme cases, superficial infections of the skin or mucous membranes may enter the bloodstream and cause systemic Candida infections. Factors that increase the risk of candidiasis include HIV/AIDS, mononucleosis, cancer treatments, steroids, stress, antibiotic usage, diabetes, and nutrient deficiency. Hormone replacement therapy and infertility treatments may also be predisposing factors. Use of inhaled corticosteroids increases risk of candidiasis of the mouth.
It is thought that the reduce efficacy of immune surveillance associated with these predisposing conditions or treatments maintain EBV in a dormant state systemically but not where EBV+ B cells are prevalent, i.e. in afflicted mucous membranes and skin. Consequently, the EBV+ cells at these sites proliferate and destroy tissue to create ulcerating lesions. Persons developing these ulcers are usually elderly.
The majority of lesions are found beneath ill-fitting dentures of long use and in patients who do not take their dentures out overnight. The lesion seems to result from a combination of chronic, mild trauma which permit frictional irritation. A poor fitting denture never acquires papillomatosis. However, there must be some unidentified predisposing factors present in those patients who develop the lesion.
For unknown reasons, these congenital abnormalities often expand during the teen or young adult years. A syrinx can also develop in patients who have a spinal cord tumor, scarring due to previous spinal trauma, or no known predisposing factors. About 30% of people with a spinal cord tumor eventually develop a syrinx. Syringomyelia is a paramedian, usually irregular, longitudinal cavity.
It is often associated with alcoholism and eating disorders and there is some evidence that presence of a hiatal hernia is a predisposing condition. Forceful vomiting causes tearing of the mucosa at the junction. NSAID abuse is also a rare association. In rare instances some chronic disorders like Ménière's disease that cause long term nausea and vomiting could be a factor.
Each character also has specific weapon-related abilities and other skills, predisposing them to particular weapon types. In addition, characters can carry up to five weapons and five items. Each weapon and item has a weight value as well, and characters who are overburdened receive penalties to movement. Two player characters can transform into werewolves, which massively increases their speed and attack.
Treatment is by reassurance, as the condition is benign, and then by correction of any predisposing factors. This may be cessation of smoking or cessation/substitution of implicated medications or mouthwashes. Generally direct measures to return the tongue to its normal appearance involve improving oral hygiene, especially scraping or brushing the tongue before sleep. This promotes desquamation of the hyperparakeratotic papillae.
Obesity is another key predisposing factor in the development of SCFE. The fracture occurs at the hypertrophic zone of the physeal cartilage. Stress on the hip causes the epiphysis to move posteriorly and medially. By convention, position and alignment in SCFE is described by referring to the relationship of the proximal fragment (capital femoral epiphysis) to the normal distal fragment (femoral neck).
In addition, "Several specific diseases are associated with metritis or endometritis. These include brucellosis, leptospirosis, campylobacteriosis, and trichomoniasis" The Merck Veterinary Manual, "Metritis and Endometritis" In cattle, bacterial infection of the uterus affects almost all animals after parturition. This does not mean they will get disease. Beef cattle rarely have disease unless they have a predisposing factor such as retained placenta or difficult parturition.
Warm antibody autoimmune hemolytic anemia (WAIHA) is the most common form of autoimmune haemolytic anemia. About half of the cases are of unknown cause, with the other half attributable to a predisposing condition or medications being taken. Contrary to cold autoimmune hemolytic anemia (e.g., cold agglutinin disease and paroxysmal cold hemoglobinuria) which happens in cold temperature (28–31 °C), WAIHA happens at body temperature.
Midgut volvulus occurs in people (usually babies) that are predisposed because of congenital intestinal malrotation. Segmental volvulus occurs in people of any age, usually with a predisposition because of abnormal intestinal contents (e.g. meconium ileus) or adhesions. Volvulus of the cecum, transverse colon, or sigmoid colon occurs, usually in adults, with only minor predisposing factors such as redundant (excess, inadequately supported) intestinal tissue and constipation.
The model has been criticized for not paying enough attention to culture and social interaction but Andersen argues this social structure is included in the predisposing characteristics component. Another criticism was the overemphasis of need and at the expense of health beliefs and social structure. However, Andersen argues need itself is a social construct. This is why need is split into perceived and evaluated.
In the context of Plato's Problem, our visual system is an innate capacity that enables us to be aware of a considerable portion of our immediate environment which enhances our conscious experience by supplementing it with an extensive environmental awareness and predisposing us to extract meaningful perceptual information. In other words, it is our biologically produced visual system that makes our perceptual experiences meaningful.
Bennett researches pathogenesis, diagnosis, treatment, prevention, and epidemiology of mycoses, particularly cryptococcosis and candidiasis. He also researches idiopathic CD4 lymphocytopenia and clinical trials of antifungal agents. Bennett and Peter Richard Williamson are studying previously healthy patients with cryptococcal meningitis to discover underlying predisposing factors and improve therapy. Despite the absence of immunosuppression, these patients are surprisingly difficult to treat compared to those with AIDS and cryptococcosis.
Black hairy tongue is a condition of the tongue in which the small bumps on the tongue elongate with black or brown discoloration, giving a black and hairy appearance. The appearance may be alarming, but it is a harmless condition. Predisposing factors include smoking, xerostomia (dry mouth), soft diet, poor oral hygiene and certain medications. Management is by improving oral hygiene, especially scraping or brushing the tongue.
Neurexins are presynaptic membrane cell-adhesion molecules that bind primarily to neuroligins, proteins that have been associated with autism. Autism is characterized by a wide range of social and cognitive deficits, which are partially attributed to faulty synaptic communication between neurons. This lack of communication is oftentimes tied to mutations in NRXN1. Structural variants of NRXN1a (neurexin1 alpha) are consistent with mutations predisposing autism.
Predisposing factors include knowledge, attitudes, beliefs, personal preferences, existing skills, and self-efficacy towards the desired behavior change. Reinforcing factors include factors that reward or reinforce the desired behavior change, including social support, economic rewards, and changing social norms. Enabling factors are skills or physical factors such as availability and accessibility of resources, or services that facilitate achievement of motivation to change behavior.Ransdell, L.B. (2001).
The role of leptin/leptin receptors in modulation of T cell activity and the innate immune system was shown in experimentation with mice. It modulates the immune response to atherosclerosis, of which obesity is a predisposing and exercise a mitigating factor. Exogenous leptin can promote angiogenesis by increasing vascular endothelial growth factor levels. Hyperleptinemia produced by infusion or adenoviral gene transfer decreases blood pressure in rats.
Silent strokes typically cause lesions which are detected via the use of neuroimaging such as MRI. The risk of silent stroke increases with age but may also affect younger adults. Women appear to be at increased risk for silent stroke, with hypertension and current cigarette smoking being amongst the predisposing factors. These types of strokes include lacunar and other ischemic strokes and minor hemorrhages.
The disease causes defoliation which increase year on year. This reduces yield of timber growth and weakens the tree, serving as a predisposing factor to other diseases. In several cases of infection, the disease can lead to complete mortality of the tree. Infection may take several years to severely reduce yield, as crown infection under 40% is directly proportional to the reduction in yield.
1971;31(6):784-789 Usually found on the oral mucosa of middle-aged persons, verruciform xanthomas have also been reported on the scrotum and penis of middle-aged to elderly Japanese males. While the most common site is the oral mucosa, lesions that occur elsewhere usually arise on the perineum or on the skin with some predisposing factor, such as lymphedema or an epidermal nevus.
Staphylococcus hominis is a coagulase-negative member of the bacterial genus Staphylococcus, consisting of Gram-positive, spherical cells in clusters. It occurs very commonly as a harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odour. Like many other coagulase-negative staphylococci, S. hominis may occasionally cause infection in patients whose immune systems are compromised, for example by chemotherapy or predisposing illness.
However it took another eight years before transgenic mice were developed that passed the transgene to their offspring. Genetically modified mice were created in 1984 that carried cloned oncogenes, predisposing them to developing cancer. Mice with genes removed (termed a knockout mouse) were created in 1989. The first transgenic livestock were produced in 1985 and the first animal to synthesize transgenic proteins in their milk were mice in 1987.
Corneal sensitization and evaporative hyperalgesia occur as a result of trauma and environmental stress, the cornea has the highest density of nociceptors of any tissue in the body, and can become more sensitive to normal environmental stimuli. Predisposing factors to developing neuropathic pain include LASIK where it can occur as a result of aberrant nerve regeneration, tear dysfunction, blepharoplasty, excessive UV light exposure, chemical injury, and trigeminal zoster.
He acknowledged that there may also be a genetic component predisposing children to the disorder. Rimland argued that autism could "be treated—or at least ameliorated—with biomedical and behavioral therapies." Infantile Autism challenged the medical establishment's perceptions of autism. Rimland's message resonated with parents and, after the book was published, he began getting calls and letters from people who wanted to share their stories and ask for advice.
Their stereoacuity is often in the range of 3000 to 70 arcsecond, and a small central suppression scotoma of 2 to 5 deg. A rare condition, MFS is estimated to affect only 1% of the general population. There are three distinguishable forms of this condition: primary constant, primary decompensating, and consecutive MFS. It is believed that primary MFS is a result of a primary sensorial defect, predisposing to anomalous retinal correspondence.
Personality is defined as consistent patterns of thoughts, feelings, and behaviors. Beck revised his original cognitive-behavioral theory to include predisposing personality types, which have been expanded upon by other cognitive-behavioral therapists. Silvano Arieti and Jules Bemporad link these consistent patterns of thought and behavior with the development of depression. They define two personality types that are vulnerable to the development of depression: dominant other and dominant goal.
In severe cases, the elevation of bradykinin may result in angioedema, a medical emergency. People of African descent have up to five times increased risk of ACE inhibitor induced angioedema due to hereditary predisposing risk factors such as hereditary angioedema. This refractory cough is a common cause for stopping ACE inhibitor therapy. Overactivation of bradykinin is thought to play a role in a rare disease called hereditary angioedema.
Small sections of necrotic bone may be resorbed completely, and larger segments may become surrounded by granulation tissue and new bone (an involucrum). Sequestra may also be revascularized by new blood vessels, cause no symptoms or become chronically infected. Sometimes the involucrum is penetrated by channels (cloacae) through which pus drains to the skin or mouth. OM of the jaws often occurs in the presence of one or more predisposing factors.
The best treatment is avoidance of conditions predisposing to attacks, when possible. In athletes who wish to continue their sport or do so in adverse conditions, preventive measures include altered training techniques and medications. Some take advantage of the refractory period by precipitating an attack by "warming up," and then timing competition such that it occurs during the refractory period. Step-wise training works in a similar fashion.
Currently, there is controversy over whether or not inheritance truly plays a role in FAD, and if so which gene it acts upon. FAD does not come from strictly one predisposing factor, such as hypertension. It is suggested that the combination of environmental factors along with genetics may contribute to causing FAD. Before newer and more effective cures and therapies can be developed, first the specific gene mutation must be identified.
This is an uncommon form of chronic (more than one month in duration) candidal infection involving multiple areas in the mouth, without signs of candidiasis on other mucosal or cutaneous sites. The lesions are variably red and/or white. Unusually for candidal infections, there is an absence of predisposing factors such as immunosuppression, and it occurs in apparently healthy individuals, normally elderly males. Smoking is a known risk factor.
Both the quantity and quality of saliva are important oral defenses against candida. Decreased salivary flow rate or a change in the composition of saliva, collectively termed salivary hypofunction or hyposalivation is an important predisposing factor. Xerostomia is frequently listed as a cause of candidiasis, but xerostomia can be subjective or objective, i.e., a symptom present with or without actual changes in the saliva consistency or flow rate.
Mutations may lead to decreased or increased activity of enzymes. This may have different consequences, depending on the normal function of the serine protease. For example, mutations in protein C can lead to protein C deficiency and predisposing to thrombosis. Also, some proteases play a vital role in host cell-virus fusion activation by priming virus's Spike protein to show the protein named "fusion protein" (TMPRSS2 activate SARS-CoV-2 fusion).
The limited venous drainage builds the blood flow resistance and adrenal venous pressure, resulting in the hemorrhage into the gland. Under physiological stress, ACTH and catecholamine secretion increases, which further promotes adrenal arterial blood flow. Increased catecholamine level constricts the venules and enhances platelet aggregation, which may induce adrenal vein thrombosis. The synergistical effect builds up pressure within the venous sinusoids, predisposing to adrenal gland congestion and venous stasis.
It is difficult to determine the exact frequency of peptostreptococcus infections because of inappropriate collection methods, transportation, and specimen cultivation. Peptostreptococcus infections are most commonly found in patients who have had or have chronic infections. Patients who have predisposing conditions are shown to have 5% higher recovery rate of the bacteria in blood cultures.Martin WJ. Isolation and identification of anaerobic bacteria in the clinical laboratory. A 2-year experience.
Salmon with fungal disease Whales, porpoises and dolphins are susceptible to fungal diseases but these have been little researched in the field. Mortalities from fungal disease have been reported in captive killer whales; it is thought that stress due to captive conditions may have been predisposing. Transmission among animals in the open sea may naturally limit the spread of fungal diseases. Infectious fungi known from killer whales include Aspergillus fumigatus, Candida albicans and Saksenaea vasiformis.
Main complications of persistent high blood pressure Complications of hypertension are clinical outcomes that result from persistent elevation of blood pressure. Hypertension is a risk factor for all clinical manifestations of atherosclerosis since it is a risk factor for atherosclerosis itself. It is an independent predisposing factor for heart failure, coronary artery disease, stroke, kidney disease, and peripheral arterial disease. It is the most important risk factor for cardiovascular morbidity and mortality, in industrialized countries.
A large number of mutations have been characterized as leading to or predisposing to LQT3. Calcium has been suggested as a regulator of SCN5A protein, and the effects of calcium on SCN5A may begin to explain the mechanism by which some of these mutations cause LQT3. Furthermore, mutations in SCN5A can cause Brugada syndrome, cardiac conduction disease, and dilated cardiomyopathy. In rare situations, some affected individuals can have combinations of these diseases.

Herbert has claimed that many children with autism have biomedical problems, and that these problems exacerbate the symptoms of autism. Her research focuses on attributing the development of autism to the existence of certain predisposing genes, with her coauthors on this topic including Peter Szatmari. In addition, some of her research focuses on the possible existence of enlarged superficial white matter in the brains of people with autism, as well as developmental language disorder.
Some of the complications of T. vaginalis in women include: preterm delivery, low birth weight, and increased mortality as well as predisposing to HIV infection, AIDS, and cervical cancer. T. vaginalis has also been reported in the urinary tract, fallopian tubes, and pelvis and can cause pneumonia, bronchitis, and oral lesions. Condoms are effective at reducing, but not wholly preventing, transmission. Trichomonas vaginalis infection in males has been found to cause asymptomatic urethritis and prostatitis.
In addition, slightly lower prevalence of the disease has been reported in black and Asian children relative to white children. In most cases, there are no clear predisposing risk factors for the development of RMS. It tends to occur sporadically with no obvious cause. However, RMS has been correlated with familial cancer syndromes and congenital abnormalities including neurofibromatosis type 1, Beckwith-Wiedemann syndrome, Li–Fraumeni syndrome, cardio-facio-cutaneous syndrome, and Costello syndrome.
Report of the Office of the Child Advocate, p.104 The authors also noted that despite multiple developmental and mental health problems, Lanza had not received adequate mental health treatment. They wrote: "It is fair to surmise that, had Lanza's mental illness been adequately treated in the last years of his life, one predisposing factor to the tragedy of Sandy Hook might have been mitigated".Report of the Office of the Child Advocate, p.
The process of compressing gas into a diving cylinder removes moisture from the gas. This is good for corrosion prevention in the cylinder but means that the diver inhales very dry gas. The dry gas extracts moisture from the diver's lungs while underwater contributing to dehydration, which is also thought to be a predisposing risk factor of decompression sickness. It is also uncomfortable, causing a dry mouth and throat and making the diver thirsty.
The true cause of ainhum remains unclear. It is not due to infection by parasites, fungi, bacteria or virus, and it is not related to injury. Walking barefoot in childhood had been linked to this disease, but ainhum also occurs in patients who have never gone barefoot. Race seems to be one of the most predisposing factors and it may have a genetic component, since it has been reported to occur within families.
K.kingae infections are rare in adults, but they occur in immunocompromised patients. Poor oral hygiene, pharyngitis, and mucosal ulceration are also predisposing factors for infection. The infection can occur in the respiratory or urinary tracts, as it is a part of the normal flora in those two areas, and will develop into sepsis or septic arthritis. Most K. kingae are sensitive to beta-lactam antibiotics, but reports describe strains producing beta-lactamases.
The proponents of these models claim that they would offer greater diagnostic flexibility and clinical utility without depending on the medical concept of illness. However, they also admit that these models are not yet robust enough to gain widespread use, and should continue to be developed. Clinical psychologists do not tend to diagnose, but rather use formulation—an individualized map of the difficulties that the patient or client faces, encompassing predisposing, precipitating and perpetuating (maintaining) factors.
4-Hydroxy-2-oxoglutarate aldolase, mitochondrial (HOGA1) also known as dihydrodipicolinate synthase-like (DHDPSL) is an enzyme that in humans is encoded by the HOGA1 gene. The protein is one of the enzymes (4-hydroxy-2-oxoglutarate aldolase) involved in metabolism of hydroxyproline to glyoxylate. The enzyme overactivity can form excessive glyoxylate from hydroxyproline. Glyoxylate is catabolised to oxalate, resulting in excess excretion of oxalate in urine, predisposing to oxalate stone; a condition known as primary hyperoxaluria type III.
After the IOL is inserted, the surgeon checks that the incision does not leak fluid. This is a very important step, since wound leakage increases the risk of unwanted microorganisms gaining access into the eye and predisposing it to endophathalmitis. An antibiotic/steroid combination eye drop is put in and an eye shield may be applied on the operated eye, sometimes supplemented with an eye patch. Antibiotics may be administered pre- operatively, intra-operatively, and/or post-operatively.
In particular, adults often present with degenerative changes of the spinal column resulting in predisposing spinal stenosis. SCI in adults could be due to instability of vertebral ligaments or a herniation of a disk or a hematoma around the spinal cord that presses on it—none of which would show up on X-rays. In older people, spondylosis or problems with blood vessels can cause SCIWORA. The most common cause is being hit by a vehicle while on foot.
How Drugs Influence Behavior. Englewood Cliffs: Prentice Hall, 1996. More recent work, however, has shown that atypical antipsychotic drugs such as clozapine and quetiapine bind and unbind rapidly and repeatedly to the dopamine D2 receptor. All of these drugs exhibit inverse agonistic effects at the 5-HT2A/2C receptors, meaning serotonin abnormalities are also involved in the complex constellation of neurologic factors predisposing one to the self reinforcing language-based psychological deficits found in all forms of psychosis.
It was a tradition that helped ensure the end of slavery in defense of the Union during the Civil War, while also predisposing many northern Protestants to look past, if not entirely forget, the ex-slaves following the war.Grant R. Brodrecht, "Our Country: Northern Evangelicals and the Union during the Civil War and Reconstruction" (PhD diss., University of Notre Dame, 2008), p.8. Historians also suggest it may have encouraged support for imperialistic United States policy among American Protestants.
Cardiovascular malformations (typically bicuspid aortic valve, coarctation of the aorta, and some other left-sided cardiac malformations) and hypertension predispose to aortic dilatation and dissection in the general population. Indeed, these same risk factors are found in more than 90% of patients with Turner syndrome who develop aortic dilatation. Only a small number of patients (around 10%) have no apparent predisposing risk factors. The risk of hypertension is increased three-fold in patients with Turner syndrome.
Hereditary cystatin C amyloid angiopathy (HCCAA) is a rare, fatal amyloid disease in young people in Iceland caused by a mutation in cystatin C. Most of the families with the defect gene can be traced to a region in the northwest of Iceland, around Breiðafjörður. Mutations in the cystatin 3 gene are responsible for the Icelandic type of hereditary cerebral amyloid angiopathy, a condition predisposing to intracerebral haemorrhage, stroke and dementia. The condition is inherited in a dominant fashion.
Ch 3. p. 37. Most mental disorders are composed of several factors, which is why one must take into account several theoretical perspectives when attempting to diagnose or explain a particular behavioral abnormality or mental disorder. Explaining mental disorders with a combination of theoretical perspectives is known as multiple causality. The diathesis–stress model emphasizes the importance of applying multiple causality to psychopathology by stressing that disorders are caused by both precipitating causes and predisposing causes.
People with type 1 diabetes mellitus who must take insulin in full replacement doses are most vulnerable to episodes of hypoglycemia. It is usually mild enough to reverse by eating or drinking carbohydrates, but blood glucose occasionally can fall fast enough and low enough to produce unconsciousness before hypoglycemia can be recognized and reversed. Hypoglycemia can be severe enough to cause unconsciousness during sleep. Predisposing factors can include eating less than usual or prolonged exercise earlier in the day.
First is an "educational diagnosis" – PRECEDE, an acronym for Predisposing, Reinforcing and Enabling Constructs in Educational Diagnosis and Evaluation. Second is an "ecological diagnosis" – PROCEED, for Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development. The model is multidimensional and is founded in the social/behavioral sciences, epidemiology, administration, and education. The systematic use of the framework in a series of clinical and field trials confirmed the utility and predictive validity of the model as a planning tool.
Additionally, reduced Cx43 expression in vascular tissue, which plays a part in ventricular remolding and healing of wounds after a myocardial infarction, are present in structural heart disease. However, the mechanisms of Cx43 in the heart are still poorly understood. Overall, these changes in Cx43 expression and oxidant stress can lead to abnormalities in the coordinated beating of the heart, predisposing it to cardiac arrhythmias. Connexons are also associated with both Type I and Type II diabetes.
Bile reflux gastritis can result from excess bile in the duodenum, lack of a pylorus as a barrier to retrograde flow, and/or decreased anterograde peristalsis of the stomach and duodenum. This can occur following gastric or biliary surgery or as primary biliary reflux. The most common predisposing surgeries are those that either remove, disrupt or bypass the pylorus, resulting in unopposed reflux of duodenal contents. Primary biliary reflux occurs in the absence of gastric surgery.
Jaenisch, R. and Mintz, B. (1974 ) Simian virus 40 DNA sequences in DNA of healthy adult mice derived from preimplantation blastocysts injected with viral DNA. Proc. Natl. Acad. 71(4): 1250–54 However it took another eight years before transgenic mice were developed that passed the transgene to their offspring. Genetically modified mice were created in 1984 that carried cloned oncogenes, predisposing them to developing cancer. Mice with genes knocked out (knockout mouse) were created in 1989.
Unlike fetal alcohol syndrome, no set of characteristics has been discovered that results uniquely from cocaine exposure in utero. Cocaine exposure in utero may affect the structure and function of the brain, predisposing children to developmental problems later, or these effects may be explained by children of crack-using mothers being at higher risk for domestic violence, deadbeat parenting, and maternal depression. When researchers are able to identify effects of PCE, these effects are typically small.
Brendan Zietsch of the Queensland Institute of Medical Research proposes the alternative theory that men exhibiting female traits become more attractive to females and are thus more likely to mate, provided the genes involved do not drive them to complete rejection of heterosexuality. Also, in a 2008 study, its authors stated that "There is considerable evidence that human sexual orientation is genetically influenced, so it is not known how homosexuality, which tends to lower reproductive success, is maintained in the population at a relatively high frequency." They hypothesized that "while genes predisposing to homosexuality reduce homosexuals' reproductive success, they may confer some advantage in heterosexuals who carry them" and their results suggested that "genes predisposing to homosexuality may confer a mating advantage in heterosexuals, which could help explain the evolution and maintenance of homosexuality in the population." In Scientific American Mind, the scientist Emily V. Driscoll stated that homosexual and bisexual behavior is quite common in several species and that it fosters bonding: "The more homosexuality, the more peaceful the species".
One of the languages under consideration was, of course, Esperanto. Zamenhof did not give permission to reprint his articles detailing his "Esperanto1894" suggestions but a reprintPri Reformoj en Esperanto: Artikoloj Publikigitaj de Dro Zamenhof en la Nurnberga gazeto “Esperantisto” dum la unua duonjaro de 1894, kopiitaj kaj represitaj per zorgo de Dro Emile Javal, Coulommiers Imprimerie Paul Brodard, 1907. was made and circulated, perhaps predisposing Committee members to think in terms of a reformed Esperanto. (There were 200 copies, distributed personally.).
Whilst the definitive cause(s) of schizophrenia remain unknown, research has indicated strong links between genetic make-up, social predisposing factors or stressors and environmental conditions in relation to the development and onset of schizophrenia and other conditions. International geneticists are working towards identifying a gene for Schizophrenia, combined efforts are at the SzGene database. In the course of this research geneticists have identified specific genes or copy number variants or alleles that may explain the comorbidity of various conditions.
In 2011, an arm of the World Health Organization released a statement listing cell phone use as a low grade cancer risk. The Acoustic Neuroma Association recommends that cell phone users use a hands-free device. Meningiomas are significantly more common in women than in men; they are most common in middle-aged women. Two predisposing factors associated with meningiomas for which at least some evidence exists are exposure to ionizing radiation (cancer treatment of brain tumors) and hormone replacement therapy.
Around this time Mahomed became acquainted with the British polymath, Francis Galton, who shared an interest in factors predisposing to disease. Mahomed and Galton collaborated to produce composite photographs of over 400 patients with phthisis (Tuberculosis), which they compared with composite photographs based on 200 individuals without evidence of phthisis to test whether, as was widely believed, appearance or looks indicated a predisposition to disease. They found no evidence of a characteristic facial appearance associated with tuberculosis beyond some evidence of emaciation.
The initial cause of a carbuncle can often not be determined. Triggers that make carbuncle infections more likely include recent incidence of folliculitis; friction from clothing or shaving; having hair pulled out, such as sites where clothing or furniture grab at hairs; generally poor hygiene; poor nutrition; or weakened immunity. Poor health may be a predisposing factor – for example, persons with diabetes and immune system diseases are more likely to develop infections (especially bacterial infections of the leg or foot).
Contraindications to facelift surgery include severe concomitant medical problems, both physical and psychological. While not absolute contraindications, the risk of postoperative complications is increased in cigarette smokers and patients with hypertension and diabetes. These strong relative contraindications consist primarily of diseases predisposing to poor wound healing. Patients are typically asked to abstain from taking aspirin or other blood thinners for at least one week prior to surgery. Patients motivations and expectations are an important factor in order to determine the patient’s medical status.
However, no evidence suggests that patients with Turner syndrome have a significantly higher risk of aortic dilatation and dissection in absence of predisposing factors. So, the risk of aortic dissection in Turner syndrome appears to be a consequence of structural cardiovascular malformations and hemodynamic risk factors rather than a reflection of an inherent abnormality in connective tissue. The natural history of aortic root dilatation is unknown, but because of its lethal potential, this aortic abnormality needs to be carefully followed.
Mild presentation of ANUG on the gums of the lower front teeth Common marginal gingivitis in response to subgingival plaque is usually a painless condition. However, an acute form of gingivitis/periodontitis, termed acute necrotizing ulcerative gingivitis (ANUG), can develop, often suddenly. It is associated with severe periodontal pain, bleeding gums, "punched out" ulceration, loss of the interdental papillae, and possibly also halitosis (bad breath) and a bad taste. Predisposing factors include poor oral hygiene, smoking, malnutrition, psychological stress, and immunosuppression.
Marsh bowled three of his victims. According to cricket historian Bernard Whimpress, the early signs of a conspiracy against Marsh were raised by a journalist from The Age of Melbourne by the name of Old Boy. The journalist set a possible agenda by raising a question about Marsh to Crockett on the day before the bowler was called, possibly predisposing the umpire to take action. If Old Boy could be relied on, then observers suspected that Marsh's faster and slower ball were dubious.
Gastropexies are also performed prophylactically in dogs considered to be at high risk of gastric dilatation- volvulus, including dogs with previous episodes of gastric dilatation-volvulus or with gastrointestinal disease predisposing to gastric dilatation-volvulus, and dogs with a first-order relative (parent or sibling) with a history of gastric dilatation-volvulus. Precautions that are likely to help prevent gastric dilatation-volvulus include feeding small meals throughout the day instead of one big meal and not exercising immediately before or after a meal.
Peptostreptococci can cause fatal endocarditis, paravalvular abscess, and pericarditis. The most frequent source of bacteremia due to Peptostreptococcus are infections of the oropharynx, lower respiratory tract, female genital tract, abdomen, skin, and soft tissues. Recent gynecological surgery, immunosuppression, dental procedures, infections of the female genital tract, abdominal and soft tissue along with gastrointestinal surgery are predisposing factors for bacteremia due to peptostreptococcus. Microaerophilic streptococci typically account for 5-10% of cases of endocarditis; however, Peptostreptococci have only rarely been isolated.

Hawkins has extensive training as an electrical engineer. Another way to describe the theory (hinted at in his book) is as a learning hierarchy of feed forward stochastic state machines. In this view, the brain is analyzed as an encoding problem, not too dissimilar from future-predicting error-correction codes. The hierarchy is a hierarchy of abstraction, with the higher level machines' states representing more abstract conditions or events, and these states predisposing lower-level machines to perform certain transitions.
ABPA should be suspected in patients with a predisposing lung disease—most commonly asthma or cystic fibrosis— and is often associated with chronic airway limitation (CAL). Patients generally present with symptoms of recurrent infection such as fever, but do not respond to conventional antibiotic therapy. Poorly-controlled asthma is a common finding, with a case series only finding 19% of ABPA patients with well-controlled asthma. Wheezing and hemoptysis (coughing up blood) are common features, and mucus plugging is seen in 31-69% of patients.
Low effortful control may also interact with negative and positive affect, predisposing individuals to substance or behavioural use, and impair their ability to control use. A general inability to control affective states may impair the conditioning of behaviour associated with rewards and punishment, may increase susceptibility to biasing by substance- related cues, and could tax self-regulatory capacity. Such conditions may render individuals unable to interrupt automatic drug-seeking behaviours. Abnormal levels of positive and negative affect can be increased by low effortful control.
Pre-existing depressive and anxiety disorders, as well as high expectation of parents and family history were predisposing factors identified in another review. People with CFS and their relatives tend to attribute their illness to physical causes (such as a virus or pollution) rather than to psychological causes, and these attributions are associated with increased symptoms and impairment, and worse outcomes over time. However, according to the CDC, "CFS is a biological illness, not a psychologic disorder", and those affected "are neither malingering nor seeking secondary gain".
Common irritants include detergents, acids, alkalies, oils, organic solvents and reducing agents. Clinical manifestations of the contact dermatitis are also modified by external factors such as environmental factors (mechanical pressure, temperature, and humidity) and predisposing characteristics of the individual (age, sex, ethnic origin, preexisting skin disease, atopic skin diathesis, and anatomic region exposed. Another occupational skin disease is glove-related hand urticaria, believed to be caused by repeated wearing and removal of the gloves. It has been reported as an occupational problem among the health care workers.
Biomedical Informatics (BMI) applies statistical techniques and technologies to the medical and health sciences. Epidemiology involves the study of disease — and the predisposing conditions for disease — among human populations in all parts of the world, with an emphasis on approaches to improving levels of health. The MS Program in Epidemiology is presented by the Department of Health Research and Policy (HRP) at the School of Medicine. Health Services Research (HSR) is concerned with the analysis of health policy in the public and private sectors.
Cognitive behavioral therapy (CBT) is based on the assumption that depression has its roots in negative thought patterns that then result in negative behavior patterns. Aaron Beck is cited as the first to develop this cognitive-behavioral approach, focusing on the here and now rather than predisposing factors. Beck's theories are based on his cognitive triad: a negative view of self, the world, and the future. Individuals with depression have unwarranted negative views of themselves and the world and, consequently, have overly negative expectations for the future.
Individual with an increased risk of developing severe mosquito bite reactions include those experiencing a particularly large number of mosquito bites, those with no previous exposure to the species of mosquito causing the bites, and those with a not fully developed immune system such as infants and young children. Individuals with certain Epstein-Barr virus-associated lymphoproliferative, non-Epstein-Barr virus malignant lymphoid, or other predisposing disease also have an increased rate of systemic mosquito bite reactions but are considered in a separate category (see below).
By the 1850s nostalgia was losing its status as a particular disease and coming to be seen rather as a symptom or stage of a pathological process. It was considered as a form of melancholia and a predisposing condition among suicides. Nostalgia was, however, still diagnosed among soldiers as late as the American Civil War.Wisconsin Public Radio, To the Best of Our Knowledge, "Svetlana Boym on Nostalgia", 2002 November 3 By the 1870s interest in nostalgia as a medical category had almost completely vanished.
Mutations or deletions of clock gene in mice have demonstrated the importance of body clocks to ensure the proper timing of cellular/metabolic events; clock-mutant mice are hyperphagic and obese, and have altered glucose metabolism. In mice, deletion of the Rev-ErbA alpha clock gene facilitates diet-induced obesity and changes the balance between glucose and lipid utilization predisposing to diabetes. However, it is not clear whether there is a strong association between clock gene polymorphisms in humans and the susceptibility to develop the metabolic syndrome.
Osteoarthritis is the most common form of arthritis. It can affect both the larger and the smaller joints of the body, including the hands, wrists, feet, back, hip, and knee. The disease is essentially one acquired from daily wear and tear of the joint; however, osteoarthritis can also occur as a result of injury. In recent years, some joint or limb deformities, such as knock-knee or acetabular overcoverage or dysplasia, have also been considered as a predisposing factor for knee or hip osteoarthritis.
Wound infection by C novyi and many other clostridium species cause gas gangrene Spontaneous infection is mostly associated with predisposing factors of hematologic or colorectal malignancies and with diabetes mellitus, although Gram-negative organisms, including Escherichia coli, may lead to a gas gangrene-like syndrome in diabetic patients. This presents with cellulitis and crepitus, and may be mistaken for gas gangrene. Spontaneous, nontraumatic, or intrinsic infections from a bowel source have been increasingly reported recently. C novyi has been implicated in mortality among injecting illegal drug users.
ASDs, and particularly PFOs, are a predisposing venous blood carrying inert gases, such as helium or nitrogen does not pass through the lungs. The only way to release the excess inert gases from the body is to pass the blood carrying the inert gases through the lungs to be exhaled. If some of the inert gas-laden blood passes through the PFO, it avoids the lungs and the inert gas is more likely to form large bubbles in the arterial blood stream causing decompression sickness.
56 the best racehorses are generally of average size.Hedge Horse Conformation p. 35 Larger horses mature more slowly and have more stress on their legs and feet, predisposing them to lameness.Barakat "Why Size Matters" Equus Smaller horses are considered by some to be at a disadvantage due to their shorter stride and a tendency of other horses to bump them, especially in the starting gate. Historically, Thoroughbreds have steadily increased in size: the average height of a Thoroughbred in 1700 was about 13.3 hands high.
There have been no controlled studies regarding this treatment. Additionally, fresh frozen plasma and human albumin transfusions can help replace the extreme protein losses seen in severe cases and help assure adequate tissue healing. However, this is controversial with the availability of safer colloids such as Hetastarch, as it will also increase the colloid osmotic pressure without the ill effect of predisposing that canine patient to future transfusion reaction. Once the dog can keep fluids down, the IV fluids are gradually discontinued, and very bland food slowly introduced.
This allele, identified by deep sequencing of GWAS loci, results in a protein with a C-terminal truncation. In a functional follow-up study, using re-expressed human CARD9 isoforms in murine Card9−/− bone marrow-derived dendritic cells (BMDCs) were assessed for cytokine production. BMDCs expressing the predisposing variant CARD9 S12N showed increased TNFα and IL-6 production compared to BMDCs expressing wild-type CARD9. In contrast, CARD9 Δ11 and CARD9 S12NΔ11, as well as the C-terminal truncated variant CARD9 V6, showed significant impairment in TNFα and IL-6 production.
As the disease progresses, it may penetrate through cornea but very rarely causes infection inside the eye (endophthalmitis) due to a robust neutrophil response in the anterior chamber. While the vast majority of cases of Acanthamoeba keratitis occur in contact lens wearers, there have been many cases of Acanthamoeba described in those who do not wear contact lenses, especially outside the United States. In non- contact lens users, the greatest risks for developing Acanthamoeba infection are trauma and exposure to contaminated water. Further predisposing factors include contaminated home water supply, and low socioeconomic status.
Inhaled corticosteroids with other risk factors such as antibiotics, oral glucocorticoids, not rinsing mouth after use of inhaled corticosteroids or high dose of inhaled corticosteroids put people at even higher risk. Treatment with antibiotics can lead to eliminating the yeast's natural competitors for resources in the oral and intestinal flora, thereby increasing the severity of the condition. A weakened or undeveloped immune system or metabolic illnesses are significant predisposing factors of candidiasis. Almost 15% of people with weakened immune systems develop a systemic illness caused by Candida species.
There are very few symptoms at or below unless patients had predisposing medical conditions or had dived recently. There is a correlation between increased altitudes above and the frequency of altitude DCS but there is no direct relationship with the severity of the various types of DCS. A US Air Force study reports that there are few occurrences between and and 87% of incidents occurred at or above . High altitude parachutists may reduce the risk of altitude DCS if they flush nitrogen from the body by pre-breathing pure oxygen.
Although the occurrence of DCS is not easily predictable, many predisposing factors are known. They may be considered as either environmental or individual. Decompression sickness and arterial gas embolism in recreational diving are associated with certain demographic, environmental, and dive style factors. A statistical study published in 2005 tested potential risk factors: age, gender, body mass index, smoking, asthma, diabetes, cardiovascular disease, previous decompression illness, years since certification, dives in the last year, number of diving days, number of dives in a repetitive series, last dive depth, nitrox use, and drysuit use.
Besides pain management and control of any predisposing factors, mechanical stabilization is a primary treatment goal once the initial inflammatory and metabolic issues have resolved. No approach has been shown to be effective in all situations, and debate is ongoing the merits and faults of the numerous techniques. Once the distal phalanx rotates, it is essential to derotate and re-establish its proper spatial orientation within the hoof capsule, to ensure the best long-term prospects for the horse. With correct trimming and, as necessary, the application of orthotics, one can effect this reorientation.
Christine Van Broeckhoven (born 9 April 1953) is a Belgian molecular biologist and professor in Molecular genetics at the University of Antwerp (Antwerp, Belgium). She is also leading the VIB Department of Molecular Genetics, University of Antwerp of the Flanders Institute for Biotechnology (VIB). Christine Van Broeckhoven does research on Alzheimer dementia,Van Broeckhoven C, Backhovens H, Cruts M, De Winter G, Bruyland M, Cras P, Martin JJ., Mapping of a gene predisposing to early-onset Alzheimer's disease to chromosome 14q24.3, Nat Genet. 1992 Dec;2(4):335-9.
The diagnosis, which may be difficult to distinguish form other skin disorders, is based on history of mosquito bites and previous or concurrent predisposing diseases, the course taken by the skin lesions, and the pathology of these lesions. Blood eosinophil levels are elevated in about half of these cases. The disorder has generally been either untreated or treated with short- or longer-term oral glucocorticoids, topical glucorocoricoids, and/or injections of glucocorticoids into the skin lesions, depending or lesion severities. Oral antihistamines are used to alleviate any associated itchiness.
Furthermore, five percent of drivers are on the phone at any given time. The Insurance Institute of Highway Safety (IIHS) reported those who used cell phones more often tended to brake harder, drive faster, and change lanes more frequently, predisposing them to crashes and near-crashes. They are also two to six times more likely to get into an accident. Research indicates driver performance is adversely affected by concurrent cell phone use, delaying reaction time and increasing lane deviations and length of time with eyes off the road.
Firstly, to sell audiences to advertisers, reporting must appeal to as broad an audience as possible and therefore focuses on “facts” that are the least controversial. Conflict processes are often controversial, so coverage of them risks alienating potential consumers, who may be sensitive to the exposure of structural or cultural predisposing factors.Lynch & McGoldrick, 2005, p. 210. Secondly, a bias in favor of official sources means that, while it may appear uncontroversial, as there is only one official representative for the government on any given issueLynch, J. & McGoldrick, A. (2009).
The terms "sickle cell crisis" or "sickling crisis" may be used to describe several independent acute conditions occurring in patients with SCD, which results in anaemia and crises that could be of many types, including the vaso-occlusive crisis, aplastic crisis, sequestration crisis, haemolytic crisis, and others. Most episodes of sickle cell crises last between five and seven days. "Although infection, dehydration, and acidosis (all of which favor sickling) can act as triggers, in most instances, no predisposing cause is identified."Kumar, Vinay; Abbas, Abul K.; Fausto, Nelson; Aster, Jon (2009-05-28).
Even before Haywood first became an official with the WFM, he was convinced that the system under which working people toiled was unjust. He described the execution of the Haymarket leaders in 1887 as a turning point in his life, predisposing him toward membership in the largest organization of the day, the Knights of Labor. Haywood had watched men die in unsafe mine tunnels, and had marched with Coxey's Army. Haywood had suffered a serious hand injury in the mines, and found that his only support came from other miners.
Since homosexuality tends to lower reproductive success, and since there is considerable evidence that human sexual orientation is genetically influenced, it is unclear how it is maintained in the population at a relatively high frequency.Zietsch et al. (2008) There are many possible explanations, such as genes predisposing to homosexuality also conferring advantage in heterosexuals, a kin selection effect, social prestige, and more. A 2009 study also suggested a significant increase in fecundity in the females related to the homosexual people from the maternal line (but not in those related from the paternal one).
The mechanism is usually the reduplication of the paternal haploid set from a single sperm, but may also be the consequence of dispermic (two sperm) fertilization of the egg. In rare cases, hydatidiform moles are tetraploid (four chromosome sets) or have other chromosome abnormalities. A small percentage of hydatidiform moles have biparental diploid genomes, as in normal living persons; they have two sets of chromosomes, one inherited from each biological parent. Some of these moles occur in women who carry mutations in the gene NLRP7, predisposing them towards molar pregnancy.
Social skills are significantly impaired in people suffering from alcoholism due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. The social skills that are impaired by alcohol abuse include impairments in perceiving facial emotions, prosody perception problems and theory of mind deficits; the ability to understand humour is also impaired in alcohol abusers. Studies have shown that alcohol dependence relates directly to cravings and irritability. Another study has shown that alcohol use is a significant predisposing factor towards antisocial behavior in children.
Commentary on the Summa Theologica of St. Thomas, "Grace", Chapter Four Prevenient grace (from the Latin "to come before") was discussed in the fifth chapter of the sixth session of the Council of Trent (1545-1563) which used the phrase: "a Dei per dominum Christum Iesum praeveniente gratia" (rendered "a predisposing grace of God through Jesus Christ").Council of Trent, session 6, chapter 5 Those who turned from God by sins are disposed by God's grace to turn back and become justified by freely assenting to that grace.
Bipolar disorder is an affective disorder characterized by periods of elevated and depressed mood. The cause and mechanism of bipolar disorder is not yet known, and the study of its biological origins is ongoing. Although no single gene causes the disorder, a number of genes are linked to increase risk of the disorder, and various gene environment interactions may play a role in predisposing individuals to developing bipolar disorder. Neuroimaging and postmortem studies have found abnormalities in a variety of brain regions, and most commonly implicated regions include the ventral prefrontal cortex and amygdala.
The diagnosis of primary Evans syndrome is made upon blood tests to confirm not only hemolytic anemia and immune thrombocytopenic purpura, but also a positive direct antiglobulin test (DAT) and an absence of any known underlying cause. In 27% to 50% of cases there is an associated malignancy or a predisposing autoimmune disease (e.g. systemic lupus erythematosus), it is then common to denote it as secondary Evans syndrome. Other antibodies may occur directed against neutrophils and lymphocytes, and "immunopancytopenia" has been suggested as a term for this syndrome.
Animal models used to study the interactions between prior degenerative disease and overlying systemic inflammation have shown that even mild systemic inflammation causes acute and transient deficits in working memory among diseased animals. Prior dementia or age-associated cognitive impairment is the primary predisposing factor for clinical delirium and "prior pathology" as defined by these new animal models may consist of synaptic loss, abnormal network connectivity, and "primed microglia" brain macrophages stimulated by prior neurodegenerative disease and aging to amplify subsequent inflammatory responses in the central nervous system (CNS).
A field defect (field cancerization) is an area of epithelium that has been preconditioned by epigenetic or genetic changes, predisposing it towards development of cancer. As pointed out by Rubin " ...there is evidence that more than 80% of the somatic mutations found in mutator phenotype human colorectal tumors occur before the onset of terminal clonal expansion." Similarly, Vogelstein et al. point out that more than half of somatic mutations identified in tumors occurred in a pre-neoplastic phase (in a field defect), during growth of apparently normal cells.
Yarwood published on a variety of plant pathology topics including fungi, powdery mildew, rusts, viruses, and predisposing factors. Some of his earlier work demonstrated that, contrary to what was previously believed, powdery mildew conidia could germinate in dry conditions. This was possible, he found, because powdery mildew fungi (Erysiphe polygoni, E. graminis, and E. cichoracearum) had 4.5 times higher water content than some other fungal conidia. He also showed that about half of all known basidiospores at the time had a vertical orientation while attached to the basidium.
The incident varies in different countries as well as within the country itself. Dental traumatic accidents depends on one's activity status and also the surrounding environment factor but these are the main predisposing risk factor compared to a person's age and gender. Trauma is the most common cause of loss of permanent incisors in childhood. Dental trauma often lead to the main complication such as pulpal necrosis, and it's nearly impossible to predict the long-term prognosis of the injured tooth and often results in long term restorative problems.
He considered them mistaken to treat their variables as isolated items, rather than in combination with each other. He also found the studies they cited as evidence that homosexuality might have a hormonal basis unconvincing. The psychologists Paul H. Van Wyk and Chrisann S. Geist wrote in the Archives of Sexual Behavior that Bell et al. question a scientific consensus, established by researchers such as the psychologists Heino Meyer-Bahlburg and John Money, that biological factors have at most only a predisposing influence on the development of sexual orientation.
While a primary infection can practically be viewed as, the root cause of an individual's current health problem, a secondary infection is a sequela or complication of that root cause. For example, pulmonary tuberculosis is often a primary infection, but an infection that happened only because a burn or penetrating trauma (the root cause) allowed unusual access to deep tissues is a secondary infection. Primary pathogens often cause primary infection and also often cause secondary infection. Usually, opportunistic infections are viewed as secondary infections (because immunodeficiency or injury was the predisposing factor).
However, insufficient information is currently available to conclusively link ochratoxin A to BEN. The toxin may require synergistic interactions with predisposing genotypes or other environmental toxicants to induce this nephropathy. Ochratoxin possibly is not the cause of this nephropathy, and many authors are in favor of aristolochic acid, that is contained in a plant: birthwort (Aristolochia clematitis). Nevertheless, although many of the pieces of scientific evidence are lacking and/or need serious re-evaluation, it remains that ochratoxin, in pigs, demonstrates direct correlation between exposure and onset and progression of nephropathy.
Post- traumatic symptoms associated with abandonment include a sequela of heightened emotional reactions (ranging from mild to severe) and habituated defense mechanisms (many of which have become maladaptive) to perceived threats or disruptions to one's sense of self or to one's connections.Susan Anderson, The Journey from Abandonment to Healing: The Five Stages that Accompany the Loss of Love. Berkley 2000, page 27. There are various predisposing psycho- biological and environmental factors that go into determining whether one's earlier emotional trauma might lead to the development of a true clinical picture of post-traumatic stress disorder.
Ulcers of the duodenum commonly occur because of infection by the bacteria Helicobacter pylori. These bacteria, through a number of mechanisms, erode the protective mucosa of the duodenum, predisposing it to damage from gastric acids. The first part of the duodenum is the most common location of ulcers since it is where the acidic chyme meets the duodenal mucosa before mixing with the alkaline secretions of the duodenum. Duodenal ulcers may cause recurrent abdominal pain and dyspepsia, and are often investigated using a urea breath test to test for the bacteria, and endoscopy to confirm ulceration and take a biopsy.
Mutations in TERT have been implicated in predisposing patients to aplastic anemia, a disorder in which the bone marrow fails to produce blood cells, in 2005. Cri du chat syndrome (CdCS) is a complex disorder involving the loss of the distal portion of the short arm of chromosome 5. TERT is located in the deleted region, and loss of one copy of TERT has been suggested as a cause or contributing factor of this disease. Dyskeratosis congenita (DC) is a disease of the bone marrow that can be caused by some mutations in the telomerase subunits.
Coeliac disease appears to be multifactorial, both in that more than one genetic factor can cause the disease and in that more than one factor is necessary for the disease to manifest in a person. Almost all people (95%) with coeliac disease have either the variant HLA-DQ2 allele or (less commonly) the HLA-DQ8 allele. However, about 20–30% of people without coeliac disease have also inherited either of these alleles. This suggests additional factors are needed for coeliac disease to develop; that is, the predisposing HLA risk allele is necessary but not sufficient to develop coeliac disease.
However, some types of phakomatoses have been found to be caused by genetic factors. Clinical studies have found Von Hippel-Lindau syndrome to be caused by a dominant inherited or de novo germline mutation, with the inherited familial cancer syndrome predisposing individuals for genetic mutations in the VHL gene. In fact, in a clinical study, 80% of individuals with Von Hippel- Lindau syndrome had an affected parent. Similarly, while individuals presenting with Neurofibromatosis Type I, cases where both parents were unaffected were extremely rare, suggesting some genetic correlation, though more research is required to determine the genetic causes.
At the time of construction, only the right portion of the dam bottom was treated with grout, likely predisposing the structure to generate a concentrated seepage of water from the left abutment during the 2006 Mid-Atlantic United States Flood. The construction of the Lake Needwood Dam was complete in 1965. The dam is owned by the Maryland-National Capital Park and Planning Commission. In 2007–2008, the earthen dam underwent a $3 million repair project to install a grout curtain below the Lake Needwood Dam to decrease seepage through its rock foundation and to upgrade the outlet control tower.
Angular cheilitis is thought to be multifactorial disorder of infectious origin, with many local and systemic predisposing factors. The sores in angular cheilitis are often infected with fungi (yeasts), bacteria, or a combination thereof; this may represent a secondary, opportunistic infection by these pathogens. Some studies have linked the initial onset of angular cheilitis with nutritional deficiencies, especially of the B(B2-riboflavin) vitamins and iron (which causes iron deficiency anemia), which in turn may be evidence of malnutrition or malabsorption. Angular cheilitis can be a manifestation of contact dermatitis, which is considered in two groups; irritational and allergic.
Premature atrial contractions (PACs), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial node and thus triggers a premature heartbeat. The exact cause of PACs is unclear; while several predisposing conditions exist, PACs commonly occur in healthy young and elderly people. Elderly people that get PACs usually don't need any further attention besides follow ups due to unclear evidence.
CT Scan of 11 cm Wilms' tumor of right kidney in 13-month-old. The majority of people with Wilms’ tumor present with an asymptomatic abdominal mass which is noticed by a family member or healthcare professional. Renal tumors can also be found during routine screening in children who have known predisposing clinical syndromes. The diagnostic process includes taking a medical history, a physical exam, and a series of tests including blood, urine, and imaging tests. Once Wilms’ tumor is suspected, an ultrasound scan is usually done first to confirm the presence of an intrarenal mass.
Besides swelling in the long plantar ligament, injury to the deep digital flexor tendon, superficial digital flexor tendon, tarsocrural lateral collateral ligament or peritendonous/periligamentous tissues in this region can contribute to the appearance of curb. Sickle-hocked conformation is a predisposing risk factor for the development of curb. (See hind leg conformation) Fluid accumulation and/or swelling are almost always found in the peritendonous/periligamentous tissues in curb, often with no additional underlying injuries. Injury to the superficial digital flexor tendon as a cause of curb is as common as injury to the long plantar ligament.
A retrospective cohort study by the Mayo Clinic held that bedside glucometry was a reliable estimate of plasma glucose with a mean difference of 7.9 mg/dL, but still may not coincide with every individual. The glucose is typically in the range of 140–300 mg/dl (7.8-16.7 mM) but occasionally can exceed 500 mg/dl (28 mM), especially if amplified by drugs or intravenous glucose. The blood glucose usually returns to normal within hours unless predisposing drugs and intravenous glucose are continued. Stress hyperglycemia is especially common in patients with hypertonic dehydration and those with elevated catecholamine levels (e.g.
Anti-inflammatory drugs and mmunomodulatory agents such as dapsone, hydroxychloroquine, cyclosporine, interferon alfa, tacrolimus, TNF inhibitors, various antifungal agents, and numerous other agents have been used to treat the disorder in case reports but their value in treating the disorder as well as MBA in the disorder is unclear. If a causative disorder triggering or predisposing to the development of eosinophilic cellulites is identified, the best treatment option is to treat this disorder. Patients with eosinophilic cellulitis should be followed to determine if their disorder progresses into a more series disease such as the hypereosinophilic syndrome, eosinophilic fasciitis, or the Churg-Strauss syndrome.
Although Malassezia appears to be the central predisposing factor in seborrhoeic dermatitis, it is thought that other factors are necessary for the presence of Malassezia to result in the pathology characteristic of the condition. This is based on the fact that high counts of Malassezia in the skin alone do not result in seborrhoeic dermatitis. Besides antifungals, the effectiveness of anti-inflammatory drugs, which reduce inflammation, and antiandrogens, which reduce sebum production, provide further insights into the pathophysiology of seborrhoeic dermatitis. Eunuchs, owing to their low androgen levels and small sebaceous glands, do not develop seborrheic dermatitis.
Though E. rostratum is a rare cause of infection in people, the species can cause a spectrum of diseases including allergic fungal sinusitis, skin and subcutaneous infections, invasive disease and occasionally keratomycosis an inflammation of the cornea. Invasive and skin infections caused by Exserohilum occur more frequently in those that are immunodeficient or have impaired immunity, these include infections in the sinuses, lungs, lining of the heart, and bone. Whereas, local trauma is a predisposing factor for skin and corneal infections. Meningitis and peripheral arthritides have also been reported pursuant to exposure to contaminated intrathecal drugs.
Periodontitis and associated conditions are recognised as a wide range of inflammatory diseases that have unique symptoms and varying consequences. In order to identify disease, classification systems have been used to categorise periodontal and gingival diseases based on their severity, aetiology and treatments. Having a system of classification is necessary to enable dental professionals to give a label to a patient's condition and make a periodontal diagnosis. A diagnosis is reached by firstly undertaking thorough examination of the patient's medical, dental and social histories, to note any predisposing risk factors (see above) or underlying systemic conditions.
A predisposing factor is tightness in the tensor fasciae latae muscle and iliotibial tract in combination with a quadriceps imbalance between the vastus lateralis and vastus medialis muscles can play a large role, found, mainly, in women with higher level the physical activity. Moreover, women with patellofemoral pain may show increased Q-angle compared with women without patellofemoral pain. Another cause of patellar symptoms is lateral patellar compression syndrome, which can be caused from lack of balance or inflammation in the joints. The pathophysiology of the kneecap is complex, and deals with the osseous soft tissue or abnormalities within the patellofemoral groove.
It could be because the children are modelling their parents' behaviour. Equally plausible, it could be that the children inherited drug-use- predisposing genes from their parent, which put them at increased risk for drug use as adults regardless of their parents' behaviour. Adoption studies, which parse the relative effects of rearing environment and genetic inheritance, find a small to negligible effect of rearing environment on smoking, alcohol, and marijuana use in adopted children, but a larger effect of rearing environment on harder drug use. Other behavioural genetic designs include discordant twin studies, children of twins designs, and Mendelian randomization.
It is likely that there are multiple factors at play that could include some amount of vasospasm and failure of the microvasculature. These factors can overlap and create the complex sequela leading to ischemia and left ventricle contraction abnormality. For instance, estrogen, which confers protection to women by improving blood flow to heart muscle, is one biochemical pathway implicated in the TTS disease process. Once this protective mechanism is reduced through the decreased production of estrogen after menopause, there is thought to be an increase in endothelial dysfunction predisposing an individual to vasoconstriction and cardiac ischemia.
Endotherms that live in very cold circumstances or conditions predisposing to heat loss, such as polar waters, tend to have specialised structures of blood vessels in their extremities that act as heat exchangers. The veins are adjacent to the arteries full of warm blood. Some of the arterial heat is conducted to the cold blood and recycled back into the trunk. Birds, especially waders, often have very well-developed heat exchange mechanisms in their legs--those in the legs of emperor penguins are part of the adaptations that enable them to spend months on Antarctic winter ice.
T. whipplei is one of the Actinomycetes, and is a distant relative of Mycobacterium avium-intracellulare and Mycobacterium paratuberculosis, explaining in part why Whipple's disease is similar to the diseases caused by these bacteria. The disease is common in farmers and those exposed to soil and animals, suggesting that the infection is acquired from these sources. Individuals who are most susceptible to the disease are those with decreased ability to perform intracellular degradation of ingested pathogens or particles, particularly within macrophages. Several studies indicate that defective T-lymphocyte (particularly TH1 population) function may be an important predisposing factor for the disease.
In 2008, the plague was commonly found in sub-Saharan Africa and Madagascar, areas that accounted for over 95% of the reported cases. In September 2009, the death of Malcolm Casadaban, a molecular genetics professor at the University of Chicago, was linked to his work on a weakened laboratory strain of Y. pestis. Hemochromatosis was hypothesised to be a predisposing factor in Casadaban's death from this attenuated strain used for research. In 2010, researchers in Germany definitely established, using PCR evidence from samples obtained from Black Death victims, that Y. pestis was the cause of the medieval Black Death.
Von Hippel–Lindau syndrome (VHL) is a dominantly inherited hereditary cancer syndrome predisposing to a variety of malignant and benign tumors of the eye, brain, spinal cord, kidney, pancreas, and adrenal glands. A germline mutation of this gene is the basis of familial inheritance of VHL syndrome. Individuals with VHL syndrome inherit one mutation in the VHL protein that causes the protein's normal function to be lost or altered. Over time, sporadic mutation in the second copy of the VHL protein can lead to carcinomas, in particular hemangioblastomas affecting the liver and kidneys, renal (and vaginal) clear cell adenocarcinomas.
Leverkühn's life unfolds in the context of, and in parallel with, the German cultural and political environment which led to the rise and downfall of Nazi Germany. But the predisposing conditions for Leverkühn's pact with the devil are set in character, and in the artistic life, the artistic processes themselves, not merely as political allegory. The interplay of layers between the narrator's historical situation, the progress of Leverkühn's madness, and the medieval legends with which Leverkühn consciously connects himself makes for an overwhelmingly rich symbolic network, an ambiguous complexity that cannot be reduced to a single interpretation.
Extension type of supracondylar humerus fractures typically result from a fall on to an outstretched hand, usually leading to a forced hyperextension of the elbow. The olecranon acts as a fulcrum which focuses the stress on distal humerus (supracondylar area), predisposing the distal humerus to fracture. The supracondylar area undergoes remodeling at the age of 6 to 7, making this area thin and prone to fractures. Important arteries and nerves (median nerve, radial nerve, brachial artery, and ulnar nerve) are located at the supracondylar area and can give rise to complications if these structures are injured.
Depression in the elderly community can have severe consequences, which is why it is an important public health problem and research area. Older adults facing this debilitating condition are less likely to endorse affective symptoms and are more likely to instead display cognitive changes, somatic symptoms, and loss of interest than are younger adults. It is comorbid with “morbidity, increased risk of suicide, decreased physical, cognitive and social functioning, and greater self-neglect”, all of which are associated with an increase in mortality. Risk factors A common pathway to depression in older adults may consist of predisposing risks as well as the life changes experienced in old age.
Men with a BRCA mutation have a dramatically elevated relative risk of developing breast cancer, but because the overall incidence of breast cancer in men is so low, the absolute risk is equal to or lower than the risk for women without a BRCA mutation. Approximately 1% to 2% of men with a BRCA1 mutation will develop breast cancer by age 70. Approximately 6% of men with a BRCA2 mutation will develop breast cancer by age 70, which is approximately equal to the risk for women without a BRCA mutation. Very few men, with or without a predisposing mutation, develop breast cancer before age 50.
Beginning in 1997 a main component of de la Chapelle's research has centered on detecting and annotating gene mutations that predispose to thyroid cancer, TC. Relying on ample experience from work with the Finnish Disease Heritage (see above) the de la Chapelle laboratory has used linkage and linkage disequilibrium analysis in search of genes with high penetrance. For genes with low penetrance, genome-wide association analysis (GWAS) has been carried out. Presently some 10 high-penetrance genes and some 15 low-penetrance variants have been found and annotated. It is becoming increasingly clear that many predisposing genes of high penetrance exist, but each is rare or ultra-rare.
It is important to realize though that ones genetic makeup, while important, is but one of an array of host factors contributing to overall adaptive capacity of the individual. In many instances, it is possible for such factors to interact in ways that may enhance or offset the effect of each other. Red blood cell conditions There is a broad group of genetic diseases that result in either producing or predisposing affected individuals to the development of hemolytic anemias. These diseases include abnormal hemoglobin, inability to manufacture one or the other of the peptide globin chains of the hemoglobin, and deficiencies of the Embden-Meyerhoff monophosphate.
Snow cites the work in his book, Deadly Cults: The Crimes of True Believers, to analyze predisposing factors that might make certain individuals more inclined than others to join cults. Snow cites Lalich and Tobias again later in his work, while discussing the experience of a woman who had been counseled by a therapist that belonged to what Snow referred to as ". . . an intensely controlling psychoanalytical cult called the Sullivanians." Captive Hearts, Captive Minds is also cited by Philip Jenkins in his book Mystics and Messiahs: Cults and New Religions in American History, in the chapter "Overrun with Messiahs", but it's not clear that he agrees with the authors' analysis.
Mixed infections, due to both aerobes and anaerobes, are commonly associated with this type of cellulitis. Typically, this includes alpha- hemolytic streptococci, staphylococci, and bacteroides' groups. Predisposing conditions for cellulitis include an insect or spider bite, blistering, an animal bite, tattoos, pruritic (itchy) skin rash, recent surgery, athlete's foot, dry skin, eczema, injecting drugs (especially subcutaneous or intramuscular injection or where an attempted intravenous injection "misses" or blows the vein), pregnancy, diabetes, and obesity, which can affect circulation, as well as burns and boils, though debate exists as to whether minor foot lesions contribute. Occurrences of cellulitis may also be associated with the rare condition hidradenitis suppurativa or dissecting cellulitis.
Some plants are impacted more than others, for instance, the damage threshold of P. alleni on soybeans is 14 nematodes/100cc or 1cm³ soil. Their vermiform shape and mobility allow them to enter the root and move freely throughout, feeding on the parenchyma tissue of the root cortex. This feeding causes a reduction of plant growth, less lateral roots, loss of cytoplasm in infected cells, redish brown necrotized lesions, as well as predisposing the damaged roots to fungi and bacteria that can initiate a secondary infection. Using their stylet, Pratylenchus nematodes secrete wall degrading enzymes that help to break down cell walls and allow for more ease of movement.
In this era of large amount of genetic and genomic data, accurate representation and identification of statistical interactions in biological/genetic/genomic data constitutes a vital basis for designing interventions and curative solutions for many complex diseases. Variations in human genome have been long known to make us susceptible to many diseases. We are hurtling towards the era of personal genomics and personalized medicine that require accurate predictions of disease risk posed by predisposing genetic factors. Computational and statistical methods for identifying these genetic variations, and building these into intelligent models for diseaseassociation and interaction analysis studies genome-wide are a dire necessity across many disease areas.
However, the cerebral cortex and cerebellum are two exceptions, which contain rich cytosolic alpha-synuclein but very low levels of mitochondrial alpha- synuclein. It has been shown that alpha-synuclein is localized in the inner membrane of mitochondria, and that the inhibitory effect of alpha-synuclein on complex I activity of mitochondrial respiratory chain is dose-dependent. Thus, it is suggested that alpha-synuclein in mitochondria is differentially expressed in different brain regions and the background levels of mitochondrial alpha-synuclein may be a potential factor affecting mitochondrial function and predisposing some neurons to degeneration. At least three isoforms of synuclein are produced through alternative splicing.
Thyroid cancers are thought to be related to a number of environmental and genetic predisposing factors, but significant uncertainty remains regarding their causes. Environmental exposure to ionizing radiation from both natural background sources and artificial sources is suspected to play a significant role, and significantly increased rates of thyroid cancer occur in those exposed to mantlefield radiation for lymphoma, and those exposed to iodine-131 following the Chernobyl, Fukushima, Kyshtym, and Windscale nuclear disasters. Thyroiditis and other thyroid diseases also predispose to thyroid cancer. Genetic causes include multiple endocrine neoplasia type 2, which markedly increases rates, particularly of the rarer medullary form of the disease.
The patient's decline of self-perception is revealed in his belief of his own blame, inferiority, and unworthiness. He also emphasized early life experiences as a predisposing factor. Adolf Meyer put forward a mixed social and biological framework emphasizing reactions in the context of an individual's life, and argued that the term depression should be used instead of melancholia. The first version of the DSM (DSM-I, 1952) contained depressive reaction and the DSM-II (1968) depressive neurosis, defined as an excessive reaction to internal conflict or an identifiable event, and also included a depressive type of manic-depressive psychosis within Major affective disorders.
Predisposing factors for Postoperative PVR are preoperative PVR, aphakia, high levels of vitreous proteins, duration of retinal detachment before corrective surgery, the size of the retinal hole or tear, intra-ocular inflammation, vitreous hemorrhage, and trauma to the eye. An equation to calculate the patient's risk for acquiring PVR is: :PVR score = 2.88 × (Grade C PVR)+ 1.85 × (Grade B PVR) + 2.92 × (aphakia) + 1.77 × (anterior uveitis) + 1.23 × (quadrants of detachment) + 0.83 × (vitreous haemorrhage) + 23 × (previous cryotherapy) 1 is added if the risk factor is present and 0 if the risk factor is absent. A patient is at a high risk for developing PVR if their PVR score is >6.33.
Such bacteria can cause a variety of diseases such as streptococcal pharyngitis, rheumatic fever, rheumatic heart disease, and scarlet fever. Although pharyngitis is mostly viral in origin, about 15 to 30% of all pharyngitis cases in children are caused by GAS; meanwhile, 5 to 20% of pharyngitis in adults are streptococcal. The number of pharyngitis cases is higher in children when compared with adults due to exposures in schools, nurseries, and as a consequence of lower host immunity. Such cases Streptococcal pharyngitis occurs more frequently from December to April (later winter to early spring) in seasonal countries, possibly due to changing climate, behavioural changes or predisposing viral infection.
Feedback mechanisms of these cytokines cause a suppression of the Th2 lymphocytes and a reduction of Th2 cytokine production (mainly IL-4, IL-5, IL-10 and IL-13). The end result is a reduction in the ability of the infected host to mount an adequate immune response to invading organisms that require a predominantly Th2 dependent response (these include parasitic infections and production of mucosal and humoral antibodies). In the central Australian Aboriginal population, HTLV-1 is thought to be related to their extremely high rate of death from sepsis. It is also particularly associated with bronchiectasis, a chronic lung condition predisposing to recurrent pneumonia.
Knottenbelt and McGarry, Squamous cell carcinoma, pg. 427 Horses with lightly pigmented skin, such as those with a gray hair coat or white faces, are especially prone to developing SCC, and some breeds, such as Clydesdales, may have a genetic predisposition. Exposure of light-colored skin to UV light has often been cited as a predisposing factor, but lesions can occur in dark skin and in areas that are not usually exposed to sunlight, such as around the anus. Buildup of smegma ("the bean" in horseman's terms) on the penis is also linked to SCC and is thought to be a carcinogen through penile irritation.
Contused lungs are less able to remove bacteria than uninjured lungs, predisposing them to infection. Intubation and mechanical ventilation further increase the risk of developing pneumonia; the tube is passed through the nose or mouth into the airways, potentially tracking bacteria from the mouth or sinuses into them. Also, intubation prevents coughing, which would clear bacteria-laden secretions from the airways, and secretions pool near the tube's cuff and allow bacteria to grow. The sooner the endotracheal tube is removed, the lower the risk of pneumonia, but if it is removed too early and has to be put back in, the risk of pneumonia rises.
Some device manufacturers have had to replace defective leads which exposed implanted individuals to unnecessary shocks or other malfunctions, in some cases possibly resulting in fatalities. The Cameron Health S-ICD had the disadvantage of being somewhat bulkier than existing ICDs. Also, this kind of ICD did not include a pacemaker, which narrowed the range of patients for whom it would be appropriate; it was estimated that a majority of patients receiving combination pacemaker/ICD implants would qualify for a pure ICD. These patients tended to have genetic or other conditions predisposing them to sudden cardiac death due to a failure of the heart of maintain a normal rhythm.
Aspergillus spores are small (2–3 μm in diameter) and can penetrate deep into the respiratory system to the alveolar level. In healthy people, innate and adaptive immune responses are triggered by various immune cells (notably neutrophils, resident alveolar macrophages and dendritic cells) drawn to the site of infection by numerous inflammatory cytokines and neutrophilic attractants (such as CXCR2 receptor ligands). In this situation, mucociliary clearance is initiated and spores are successfully phagocytosed, clearing the infection from the host. In people with predisposing lung diseases—such as persistent asthma or cystic fibrosis (or rarer diseases such as chronic granulomatous disease or Hyper-IgE syndrome)—several factors lead to an increased risk of ABPA.
However, researchers in France found personal and work- related factors were associated with de Quervain's disease in the working population; wrist bending and movements associated with the twisting or driving of screws were the most significant of the work-related factors. Proponents of the view that De Quervain syndrome is a repetitive strain injury consider postures where the thumb is held in abduction and extension to be predisposing factors. Workers who perform rapid repetitive activities involving pinching, grasping, pulling or pushing have been considered at increased risk. These movements are associated with many types of repetitive housework such as chopping vegetables, stirring and scrubbing pots, vacuuming, cleaning surfaces, drying dishes, pegging out washing, mending clothes, gardening, harvesting and weeding.
Studies have found that the incidence of PTE ranges between 1.9 and more than 30% of TBI sufferers, varying by severity of injury and by the amount of time after TBI for which the studies followed subjects. Brain trauma is one of the strongest predisposing factors for epilepsy development, and is an especially important factor in young adults. Young adults, who are at the highest risk for head injury, also have the highest rate of PTE, which is the largest cause of new- onset epilepsy cases in young people. Children have a lower risk for developing epilepsy; 10% of children with severe TBI and 16–20% of similarly injured adults develop PTE.
42 of Dread -that force which at one and the same time attracts and repels from the suspected danger of a fall and is present even in the state of innocence, in children. It finally results in a kind of "dizziness" which is fatal. Yet, so Kierkegaard contends, the "fall" of man is, in every single instance, due to a definite act of the will, a "leap" – which seems a patent contradiction. To the modern reader, this is the least palatable of Kierkegaard's works, conceived as it is with a sovereign and almost medieval disregard of the predisposing undeniable factors of environment and heredity (which, to be sure, poorly fit his notion of the absolute responsibility of the individual).
Darwin's autobiography says of his father, "... [he] was a little unjust to me when I was young, but afterwards I am thankful to think that I became a prime favourite with him." Bradbury quotes J. Huxley and H.B.D. Kettlew: "The predisposing cause of any psychoneurosis which Charles Darwin displayed seems to have been the conflict and emotional tension springing from his ambivalent relations with his father ... whom he both revered and subconsciously resented." Bradbury also quotes John Chancellor's analysis: "... [Darwin's] obsessive desire to work and achieve something was prompted by hatred and resentment of his father, who had called him an idler and good-for-nothing during his youth." Such psychoanalysis remains controversial, particularly when based only on writings.
Different psychological schools or models utilize clinical formulations, including cognitive behavioral therapy (CBT) and related therapies: systemic therapy, psychodynamic therapy, and applied behavior analysis. The structure and content of a clinical formulation is determined by the psychological model. Most systems of formulation contain the following broad categories of information: symptoms and problems; precipitating stressors or events; predisposing life events or stressors; and an explanatory mechanism that links the preceding categories together and offers a description of the precipitants and maintaining influences of the person's problems. Behavioral case formulations used in applied behavior analysis and behavior therapy are built on a rank list of problem behaviors, from which a functional analysis is conducted, sometimes based on relational frame theory.
Lupus anticoagulant, a circulating inhibitor predisposing for thrombosis, may skew PT results, depending on the assay used. Variations between various thromboplastin preparations have in the past led to decreased accuracy of INR readings, and a 2005 study suggested that despite international calibration efforts (by INR) there were still statistically significant differences between various kits, casting doubt on the long-term tenability of PT/INR as a measure for anticoagulant therapy. Indeed, a new prothrombin time variant, the Fiix prothrombin time, intended solely for monitoring warfarin and other vitamin K antagonists has been inventedGudmundsdottir BR, Francis CW, Bjornsdottir AM, Nellbring M, Onundarson PT. Thromb Res. 2012 Oct;130(4):674-81. doi: 10.1016/j.thromres.2011.12.013.
In a groundbreaking study in psychopathy or criminal behavior, Mednick, William Gabrielli, and Barry Hutching in an article for Science showed anti-social behavior to have a genetic component, at least in relation to property crimes. Using an adoption paradigm, the authors found no correlation between criminal conviction in the adoptive parents and their children, but there was a correlation between biological father conviction and child conviction. The authors stressed that genetic influences do not mean that anti-social behavior is completely genetically determined, but that it has a genetic component. Earlier in his career, Mednick had hypothesized that autonomic under-arousal may be a genetic factor predisposing to anti-social behavior because under-arousal slows the socialization process.
This additional post- menopausal peak of late-onset schizophrenia in women calls into question the etiology of the disease and raises a debate about "subtypes" of schizophrenia, with men and women being susceptible to different types (see Causes of Schizophrenia). This is further supported by the variability in presentation of the disease between the genders. Other theories that may explain this difference include protective or predisposing factors in men or women that may render them more (or less) susceptible to the disease at different points in life. For example, estrogen may be a protective factor for women, as estradiol has been found to be effective in treating schizophrenia when added to antipsychotic therapy.
Research shows that pre-exposure prophylaxis (PrEP) is generally safe and well tolerated for most individuals, although some side effects have been noted to occur. Some people experience a "start-up syndrome" involving nausea, headache, and/or stomach issues, which generally resolve within a few weeks of starting the PrEP medication. Research has shown that the use of Truvada as PrEP has been associated with mild to moderate declines in kidney function, mostly associated with older people over 50, those with predisposing conditions such as diabetes, or glomerular filtration rate lower than 90. These declines were usually of no concern, stabilized after several weeks of being on the drug, and reversed once the drug was discontinued.
In 41% of patients with MTS skin lesions appeared either before or during the time of diagnosis of the primary malignancy. Studies have shown that cancerous lesions in MTS develop as a result of mutations in DNA mismatch repair genes (MMR), which lead to a buildup of unstable microsatellite sequences and replications errors, predisposing one to different malignancies. Given that this is an autosomal dominant condition with multiorgan involvement, diagnosis requires a thorough medical history and physical in suspected cases of SGc in order to rule out potential visceral tumors. A number of SGc associated mutated proteins (B-catenin, p 53, p21, Shh, Androgen receptor, E-cadherin) have been shown to cause dysregulation in cell signaling.
Death in Rome deals with the careers of former National Socialists after World War II. The novel is sharply critical of Germany's past, post-war reality and future, sounding a warning and a prophetic note. Koeppen targets German militarism, revealing the dangerous influence of fascist ideology on certain West German social strata. The story, of victims and perpetrators from the time of National Socialism meeting during the post-war period, takes place against the backdrop of Rome. The city also functions as a metaphor, its ancient monuments predisposing the reader to reflect on the fate of the world, the nature of good and evil, war and peace, the past and the future, wealth and poverty, justice and social oppression.
There are multiple factors that can contribute to the development of HAPE, including sex (male), genetic factors, prior development of HAPE, ascent rate, cold exposure, peak altitude, intensity of physical exertion, and certain underlying medical conditions (eg, pulmonary hypertension). Anatomic abnormalities that are predisposing include congenital absence of pulmonary artery, and left-to-right intracardiac shunts (eg, atrial and ventricular septal defects), both of which increase pulmonary blood flow. HAPE-susceptible (HAPE-s) individuals were also found to be four times more likely to have a patent foramen ovale (PFO) than those who were HAPE- resistant. There is currently no indication or recommendation for people with PFO to pursue closure prior to extreme altitude exposure.
Posterior ischemic optic neuropathy (PION) is a medical condition characterized by damage to the retrobulbar portion of the optic nerve due to inadequate blood flow (ischemia) to the optic nerve. Despite the term posterior, this form of damage to the eye's optic nerve due to poor blood flow also includes cases where the cause of inadequate blood flow to the nerve is anterior, as the condition describes a particular mechanism of visual loss as much as the location of damage in the optic nerve. In contrast, anterior ischemic optic neuropathy (AION) is distinguished from PION by the fact that AION occurs spontaneously and on one side in affected individuals with predisposing anatomic or cardiovascular risk factors.
Currently, it is unknown whether there is any genetic link to the disease. Although any age, breed, or sex of cat can develop feline hyperesthesia syndrome, it has been noted that Abyssinian, Burmese, Himalayan and Siamese breeds appear to have an increased risk of developing the disease, therefore there is the possibility of a genetic link. It has also been observed that injury could be a predisposing factor of feline hyperesthesia syndrome. However, because injuries affect cats in numerous ways; increasing their stress and anxiety as well as affecting their physical well-being, this knowledge does not settle the debate on whether the condition is behavioural, epileptic or an umbrella term for several underlying conditions.
Recent prospective studies also indicate elderly people are at increased risk of developing new-onset hypertension following ESWL. In addition, a retrospective case-control study published by researchers from the Mayo Clinic in 2006 has found an increased risk of developing diabetes mellitus and hypertension in people who had undergone ESWL, compared with age and gender-matched people who had undergone nonsurgical treatment. Whether or not acute trauma progresses to long-term effects probably depends on multiple factors that include the shock wave dose (i.e., the number of shock waves delivered, rate of delivery, power setting, acoustic characteristics of the particular lithotriptor, and frequency of retreatment), as well as certain intrinsic predisposing pathophysiologic risk factors.
The CWE has turned its attention to the ethical, legal, and medical issues arising from research revealing that Ashkenazi Jewish women have higher-than-average frequencies of gene mutations predisposing them to breast and ovarian cancer. The 1996 conference, "Understanding the Genetics of Breast Cancer: Implications for Treatment, Policy and Advocacy," organized by national CWE, has been duplicated by AJCongress regions nationwide. In 2000, CWE presented Cancer Genetics in the Ashkenazi Community, to explore medical breakthroughs since the first conference as well as new developments in genetic testing. This follow-up conference was distinctly more upbeat than its predecessor, both in terms of medical preventive measures and in regard to legislation to ensure privacy and eliminate discrimination based on testing.
As many of these factors may occur together (poor dental structure leading to decreased food intake, followed by a stressful veterinary dental procedure to correct the dental problem) establishing a root cause may be difficult. GI stasis is sometimes misdiagnosed as "hair balls" by veterinarians or rabbit keepers not familiar with the condition.House Rabbit Society: Sluggish Motility in the Gastrointestinal TractUniversity of Miami Department of Biology: Gastrointestinal Stasis, The Silent Killer While fur is commonly found in the stomach following a fatal case of GI stasis, it is also found in healthy rabbits. Molting and chewing fur can be a predisposing factor in the occurrence of GI stasis, however, the primary cause is the change in motility of the gut.
Despite being one of only two species of medical interest within the genus Coniochaeta, Coniochaeta hoffmannii is rarely encountered as a pathogen primarily due to its related taxa. It is one of the more predominant species of its genus concerning the number of clinical cases reporting infection, having been associated with cases of subcutaneous infections, keratitis, sinusitis, and peritonitis. Coniochaeta hoffmannii rarely causes disease, but when it does, it is only seen in immunocompromised patients, thus marking it as an opportunistic fungal pathogen. Other identifying factors for opportunistic pathogens like this include an association with other underlying diseases capable of compromising the host's immune system, an association with new therapeutic modalities, and cases of invasive fungal sinusitis with no determinable predisposing factors.
The 6th iteration of Andersen's conceptual framework focuses on the individual as the unit of analysis and goes beyond health care utilization, adopting health outcomes as the endpoint of interest. This model is further differentiated from its predecessors by using a feedback loop to illustrate that health outcomes may affect aspects such as health beliefs, and need. It added genetic susceptibility as a predisposing determinant and quality of life as an outcome By using the framework's relationships we can determine the directionality of the effect following a change in an individual's characteristics or environment. For example, if one experiences an increase in need as a result of an infection, the Andersen model predicts this will lead to an increased use of services (all else equal).
Due to the unnatural motion required to throw it, the curveball is considered a more advanced pitch and poses inherent risk of injury to a pitcher's elbow and shoulder. There has been a controversy, as reported in The New York Times, March 12, 2012, about whether curveballs alone are responsible for injuries in young pitchers or whether it is the number of pitches thrown that are the predisposing factor. In theory, allowing time for the cartilage and tendons of the arm to fully develop would protect against injuries. While acquisition of proper form might be protective, Dr. James Andrews is quoted in the article as stating that in many children, insufficient neuromuscular control, lack of proper mechanics, and fatigue make maintenance of proper form unlikely.
In the process, however, the squirrel may protect its relatives within the local group (along with the rest of the group). Therefore, if the effect of the trait influencing the alarm call typically protects the other squirrels in the immediate area, it will lead to the passing on of more copies of the alarm call trait in the next generation than the squirrel could leave by reproducing on its own. In such a case natural selection will increase the trait that influences giving the alarm call, provided that a sufficient fraction of the shared genes include the gene(s) predisposing to the alarm call. Synalpheus regalis, a eusocial shrimp, also is an example of an organism whose social traits meet the inclusive fitness criterion.
To help with diagnosis, the clinician can watch out for predisposing factors, such as: birth asphyxia, meconium aspiration, use of NSAIDs (non steroidal anti- inflammatory drugs) and SSRIs (selective serotonin reuptake inhibitors) by the mother, and early onset sepsis or pneumonia. To diagnose a fetus with pulmonary hypertension, PVR must be higher than systemic vascular resistance, resulting in high afterload and decreased systemic blood flow. This causes a significant decrease in oxygen concentration, which clinically manifests as insufficient blood flow to the lower body, while there is adequate circulation to the head and right side of the body. Other echocardiographic findings in PPHN include right ventricular hypertrophy, deviation of the ventricular septum, tricuspid regurgitation, and shunting at the patent foramen ovale.
While common in animals, it was once thought to be an extremely rare infection in humans and to occur almost always in those who are immunocompromised. However,H. cinaedi infections are now regarded as more common than previously thought and to occur not only in immunocompromised individuals but also in individuals suffering various types of medical conditions that are not associated with defective immunity, in patients as part of a nosocomial (i.e. hospital-acquired) infection, and, to a lesser extent, in immunocompetent individuals who have no known predisposing medical conditions. In particular, studies conducted in Japan indicate that H. Cinaedi infections can occur in groups of individuals who are associated with each other in non-hospital and non-medical settings.
Thus, in the near future, public health genomics, and more specifically environmental health, will become an important part of the future healthcare-related issues. Potential benefits of uncovering the human genome will be focused more on identifying causes of disease and less on treating disease, through: improved diagnostic methods, earlier detection of a predisposing genetic variation, pharmacogenomics and gene therapy. For each individual, the experience of discovering and knowing their genetic make-up will be different. For some individuals, they will be given the assurance of not obtaining a disease, as a result of familial genes, in which their family has a strong history and some will be able to seek out better medicines or therapies for a disease they already have.
The use of portable ultrasound for mountainside diagnostics has been reviewed and appears to be a plausible tool for diagnosing some of the common injuries associated with the sport. Four to eight percent of snowboarding injuries take place while the person is waiting in ski-lift lines or entering and exiting ski lifts. Snowboarders push themselves forward with a free foot while in the ski-lift line, leaving the other foot (usually that of the lead leg) locked on the board at a 9–27 degree angle, placing a large torque force on this leg and predisposing the person to knee injury if a fall occurs.Davidson TM, Laliotis AT (1996) Snowboarding injuries, a four-year study with comparison with alpine ski injuries.
This lymphoma also belongs to a group of lymphoid neoplasms with plasmablastic differentiation that involve malignant plasmablasts but differ from PEL in the types of tissues where they accumulate, the gene abnormalities they carry, and/or the predisposing conditions involved in their development. More than 50, 30, and 60% of all PEL cases, respectively, develop in individuals who already have KSHV/HHV8-positive Karposi's sarcoma, human herpesvirus 8-associated multicentric Castleman disease, and/or (especially in HIV-positive individuals) evidence of bearing EBV-infected plasmsmablasts. Primary effussion lymphoma is an extremely aggressive cancer that is highly resistant to various chemotherapy treatments. It has carried a median survival time of ~5 months, with overall survival rates at 1, 3, and 5 year of only 30, 18, and 17%, respectively.
Her research group at the UCL Institute of Child Health, in collaboration with others in Europe, identified a number of genes responsible for syndromic and non-syndromic forms of deafness, including X-linked deafness, the cardio-auditory syndrome, and Usher syndrome. Their research explored the expression and functional effects of mutations identified in these genes in patients in order to understand how they give rise to disease. Bitner-Glindzicz's work on Usher syndrome initiated the National Collaborative Usher Study, a large clinical and molecular study of people with Usher syndrome in the UK, in collaboration with Karen Steel at the Wellcome Trust Sanger Institute. In addition, she was interested in ototoxicity and the mechanisms and genetic basis of this, exploring whether near-bedside genetic testing for mutations predisposing to ototoxicity was feasible.
Although most of the black men they studied had jobs and had been in Detroit an average of more than 10 years, Akers and Fox characterized them as unskilled and unsettled; they stressed the men's Southern heritage as predisposing them to violence. Additionally, a commission was established to determine the cause of the riot, despite the obvious and unequal amount of violence toward blacks. Later, it was found that the commission was extremely biased; it blamed the riot on blacks and their community leaders. Detroit's Black leaders identified numerous other substantive causes, including persistent racial discrimination in jobs and housing, frequent police brutality against Blacks and the lack of Black representation on the force, and the daily animosity directed at their people by much of Detroit's white population.
Maternal rats fed a PR-diet during the entire length of pregnancy led to metabolic-related problems in the F1 and F2 generations, even with normal nutrition during the F1 pregnancy. These effects have also been seen in the F3 generation depending on the length of protein restriction. If protein restriction occurred solely during pregnancy, the F1 and F2 offspring had higher systolic blood pressure and lower nephron numbers, possibly predisposing them to hypertension. Altered glucose utilization was detected in the grand-offspring of maternal rats fed a PR-diet during pregnancy and lactation, potentially resulting in diabetes later on in life Protein-restriction in the F0 generation led to hypomethylation of promoters involved in metabolism in the F1 and F2 generations, even though the F1 pregnant rat was given a normal diet.
Because of the very short time between presentation of mastitis and breast cancer in this study it is considered very unlikely that the inflammation had any substantial role in carcinogenesis, rather it would appear that some precancerous lesions may increase the risk of inflammation (hyperplasia causing duct obstruction, hypersensitivity to cytokines or hormones) or the lesions may have common predisposing factors. A very serious type of breast cancer called inflammatory breast cancer presents with similar symptoms as mastitis (both puerperal and nonpuerperal). It is the most aggressive type of breast cancer with the highest mortality rate. The inflammatory phenotype of IBC is thought to be mostly caused by invasion and blocking of dermal lymphatics, however it was recently shown that NF-κB target genes activation may significantly contribute to the inflammatory phenotype.
Elizabeth's father was called to parliament by Edward II and served him as Seneschal of Gascony,Fulk Lestrange at the Gascon Rolls Project (1317–1478), accessed 4 December 2013 the head of the administration of the remaining Plantagenet possessions in France. The title could be passed through both male and female, and the tortuous line of descent of the Le Stranges may have been one of the factors predisposing the Corbets towards reinforcing male primogeniture through dubious property transactions. From 1383 it passed via female descent and marriage to the Talbot family, and was one of the many titles collected together by John Talbot, Baron Furnivall and later Earl of Shrewsbury. Joan was the widow of Robert de Harley of Willey and had a daughter and heiress, Alice, who married Sir Hamo Peshall or Hamon Peshale.
De Alwis MCL (1999) Haemorrhagic septicaemia. Canberra: Australian Centre for International Agricultural Research. pp. 1–10. The disease also occurs, but to a lesser extent, in the Middle East and Africa. Predisposing conditions are not as clearly defined as in South Asia. In India from 1974–1986, HS was responsible for the highest mortality rate of infectious diseases in buffaloes and cattle, and was second in its morbidity rate in the same animals.

The specific cause is dependent of the type of TMA that is presented, but the two main pathways that lead to TMA are external triggers of vascular injury, such as viruses, bacterial Shiga toxins or endotoxins, antibodies, and drugs; and congenital predisposing conditions, including decreased levels of tissue factors necessary for the coagulation cascade. Either of these pathways will result in decreased endothelial thromboresistance, leukocyte adhesion to damaged endothelium, complement consumption, enhanced vascular shear stress, and abnormal vWF fragmentation. The central and primary event in this progression is injury to the endothelial cells, which reduces the production of prostaglandin and prostacyclin, ultimately resulting in the loss of physiological thromboresistance, or high thrombus formation rate in blood vessels. Leukocyte adhesion to the damaged endothelial wall and abnormal von Willebrand factor (or vWF) release can also contribute to the increase in thrombus formation.
The genetic component appears to be inherited in an autosomal dominant fashion with high genetic penetrance but variable expressivity in females; this means that each child has a 50% chance of inheriting the predisposing genetic variant(s) from a parent, and, if a daughter receives the variant(s), the daughter will have the disease to some extent. The genetic variant(s) can be inherited from either the father or the mother, and can be passed along to both sons (who may be asymptomatic carriers or may have symptoms such as early baldness and/or excessive hair) and daughters, who will show signs of PCOS. The phenotype appears to manifest itself at least partially via heightened androgen levels secreted by ovarian follicle theca cells from women with the allele. The exact gene affected has not yet been identified.
These seminal findings led Henri to propose a model that changed the thinking in the field: namely, that rather than being a consequence of alcoholism, this underlying neural hyperexcitability was a predisposing factor leading to the development of alcoholism and related disorders. This innovative study was replicated throughout the world and launched him on a systematic search to elucidate the genetic vulnerability underlying a predisposition toward alcoholism and related disorders. In 1990, with his foresight and charismatic leadership, Henri Begleiter was instrumental in assembling scientists in various domains to organize the large Collaborative Studies on Genetics of Alcoholism — COGA, which he has led since its inception. Under his leadership, with a strong emphasis on novel approaches such as using brain oscillations as endophenotypes, COGA has successfully identified several genes involved in the predisposition to develop alcoholism and related disorders, and this approach is still state-of-the-art today.
Misfiring and fatiguing of the VMO causes mal-tracking of the patella and subsequent damage to surrounding structures creating increased force on the knees, often resulting in injuries such as patellofemoral pain syndrome, anterior cruciate ligament rupture, chondromalacia, and tendinitis. Through the use of electromyography, researchers can evaluate and record the electrical activity produced by the skeletal muscle of the VMO to analyze the biomechanics and detect any possible abnormalities, weakness, or fatigue. With an analysis of muscle activity of the VMO through the use of electromyography, proper rehabilitative plans and goals can be established to not only correct the already established abnormality, but even prevent such injuries if tested sooner. Preventing injuries is crucial as well as teaching proper training techniques to ensure there are no valgus collapse forces causing unplanned stress on other structures of the knee, causing asymmetry, and predisposing that individual for injury.
These metabolic and visible injury responses seemed to be related to the differences in S uptake owing in part to higher gas exchange rates for deciduous species than for conifers. Conifers growing in oil sands tailings responded to SO2 with a significantly more rapid decrease in NAR compared with those growing in the Brunisol, perhaps because of predisposing toxic material in the tailings. However, sulphur uptake and visible symptom development did not differ between conifers growing on the 2 substrates. Acidification of precipitation by anthropogenic, acid-forming emissions has been associated with damage to vegetation and reduced forest productivity, but 2-year-old white spruce that were subjected to simulated acid rain (at pH 4.6, 3.6, and 2.6) applied weekly for 7 weeks incurred no statistically significant (P 0.05) reduction in growth during the experiment compared with the background control (pH 5.6) (Abouguendia and Baschak 1987).Abouguendia, Z.M.; Baschak, L.A. 1987.
Values of the global or local safety factors close to 1 (typically comprised between 1 and 1.3, depending on regulations) indicate marginally stable slopes that require attention, monitoring and/or an engineering intervention (slope stabilization) to increase the safety factor and reduce the probability of a slope movement. A previously stable slope can be affected by a number of predisposing factors or processes that make the safety factor decrease - either by increasing the shear stress or by decreasing the shear strength - and can ultimately result in slope failure. Factors that can trigger slope failure include hydrologic events (such as intense or prolonged rainfall, rapid snowmelt, progressive soil saturation, increase of water pressure within the slope), earthquakes (including aftershocks), internal erosion (piping), surface or toe erosion, artificial slope loading (for instance due to the construction of a building), slope cutting (for instance to make space for roadways, railways or buildings), or slope flooding (for instance by filling an artificial lake after damming a river).
14, 2007 Pinel noted, for example, that: "being held in esteem, having honor, dignity, wealth, fame, which though they may be factitious, always distressing and rarely fully satisfied, often give way to the overturning of reason". He spoke of avarice, pride, friendship, bigotry, the desire for reputation, for conquest, and vanity. He noted that a state of love could turn to fury and desperation, and that sudden severe reversals in life, such as "from the pleasure of success to an overwhelming idea of failure, from a dignified state—or the belief that one occupies one—to a state of disgrace and being forgotten" can cause mania or 'mental alienation'. He identified other predisposing psychosocial factors such as an unhappy love affair, domestic grief, devotion to a cause carried to the point of fanaticism, religious fear, the events of the revolution, violent and unhappy passions, exalted ambitions of glory, financial reverses, religious ecstasy, and outbursts of patriotic fervor.
A study by Green and Eversole published in 1989 reported on 9 individuals afflicted with HIV/AIDS who presented with lymphomatous masses in the oral cavity; these lymphomas were populated by apparently malignant Epstein-Barr virus-infected plasmablasts that did not express T-cell lymphocyte marker proteins. Eight years later, Delecluse and colleagues described a lymphoma, which they termed plasmablastic lymphoma, that had some features of a diffuse large B-cell lymphoma but unlike this lymphoma developed exclusively in the oral cavity, consisted of plasmablasts that lacked B-cell as well as T cell marker proteins and, in 15 of 16 cases, were infected with EBV. In 2008, the World Health Organization recognized this lymphoma as a variant of the diffuse large cell lymphomas. Subsequent to this recognition, numerous studies found this lymphoma to occur in a wide range of tissues besides the oral cavity and in individuals with various other predisposing immunodeficiency conditions.
Other possible sources of M. fortuitum infection include implanted devices such as catheters, injection site abscesses, and contaminated endoscopes. Recent publication on Rapidly Growing Mycobacteria (RGM) is available provides the following aspects of RGM: (i) its sources, predisposing factors, clinical manifestations, and concomitant fungal infections; (ii) the risks of misdiagnoses in the management of RGM infections in dermatological settings; (iii) the diagnoses and outcomes of treatment responses in common and uncommon infections in immunocompromised and immunocompetent patients; (iv) conventional versus current molecular methods for the detection of RGM; (v) the basic principles of a promising MALDI-TOF MS, sampling protocol for cutaneous or subcutaneous lesions and its potential for the precise differentiation of M. fortuitum, M. chelonae, and M. abscessus; and (vi) improvements in RGM infection management as described in the recent 2011 Clinical and Laboratory Standards Institute (CLSI) guidelines, including interpretation criteria of molecular methods and antimicrobial drug panels and their break points [minimum inhibitory concentrations (MICs)], which have been highlighted for the initiation of antimicrobial therapy (Kothavade RJ et al., 2012).
According to LeVay, there is evidence that levels of prenatal hormones, such as testosterone, influence the development of a person's sexual orientation. LeVay suggests that genes that cause a predisposition to homosexuality could persist despite the presumed lower reproductive success of gay people, through a mechanism similar to that involved in the disease sickle cell anemia, which persists because, while persons who carry two copies of the gene develop the disease, those with only one copy gain resistance to malaria. LeVay writes that there are several possible mechanisms by which genes predisposing persons of one sex to homosexuality might increase the reproductive potential of persons of the opposite sex, for example, the economist Edward M. Miller's proposal that the inheritance of a limited number of "feminizing" genes might make males more attractive to females by giving them increased empathy and kindness, or rendering them less aggressive, in turn making them more successful in reproductive terms, while a larger number of feminizing genes might result in male homosexuality. LeVay writes that a study has provided supporting evidence.
The predisposing conditions described in the previous paragraph can serve to enhance the ability of the plasmablasts in PBL to: avoid the host's immune surveillence; survive for prolonged periods, grow excessively, and acquire pro-malignant gene abnormalities. Some of the gene abnormalities found in PBL include: 1) increased expression of the MYC proto-oncogene due to its rearrangement with an antibody gene by genetic recombination or, less commonly, other causes (Myc protein, the product of this gene, enhances cell proliferation, inhibits apoptosis, and promotes maliganancy); 2) loss in the expression of the PRDM1 gene whose product, PRDM1/BLMP1 protein, represses the expression of Myc protein;) 3) frequent duplications in certain areas of chromosomes 1, 7, 11, and 22 (these duplications are similar to those often seen in diffuse large cell lymphoma); 4) reduced expression of at least 13 genes that are involved in B-cell responses to signaling agents. 5) increased expression of genes which promote the maturation of B-cells toward plasma cells (e.g. CD38, CD138, IR4/MUM1, XBP1, IL21R, and, as just indicated, PRDM1); and 6) reduced expression of genes characteristic of B-cells (e.g.
Ischemia may occur as a result of vasospasm, thrombosis, or vascular compression sometimes as a result of an increase in the amount of lactotroph cells throughout gestation (contributing to the enlargement of the pituitary gland). Necrosis may occur as a result of severe hypotension or shock due to excessive uterine bleeding following childbirth. Sheehan’s syndrome may occur as a result of the arterial constriction and abnormal hypotension in conjunction with an insufficiency to meet the increased demand in blood supply of the pituitary gland seen during pregnancy. This increased blood-flow and metabolic demand is associated with the previously mentioned hyperplasia of lactotrophs. Some possible predisposing factors to Sheehan’s syndrome may include: inherited or acquired disseminated blood coagulation (DIC), restriction pituitary blood supply, small sella size, vasospasm, or thrombosis. Post-Partum Hemorrhaging (PPH) is believed to be a predictor of Sheehan’s syndrome, so the symptoms of anaemia, obesity, and advanced maternal age may increase the risk of Sheehan Syndrome. Atony of the uterus may be related to PPH that could induce Sheehan’s syndrome. This results in the abnormally prolonged flow of blood to the placenta after delivery.
