The assay reveals cytopathic effects on cell culture monolayers characterized by rounding of fibroblasts (Fig generic 30 gm acticin with visa. Preincubation with neutralizing antibodies against the toxins demonstrates the specificity of the cytotoxicity acticin 30gm on line. The major disadvantage of the cytotoxin assay is that it is technically demanding and expensive, and many laboratories lack the expertise and equipment to provide rapid turnaround (25). The disadvantage is the low sensitivity (70–80%) linked to the fact that it requires a large amount of toxins (100–1000 pg) for detection. The relatively high false-negative rate can be decreased by 5% to 10% by repeating two to three specimens but this also increases the cost. A study by Ticehurst (46) indicate that this two-step method has good sensitivity, specificity, and cost although there is a 24-to 48-hour delay in reporting results. Supportive measures such as intravenous fluid and electrolyte replenishment should be instituted if necessary. Use of antiperistaltic agents, such as narcotics and loperamide, should be avoided as they may promote the development of toxic megacolon (6). Vancomycin, administered via retention enemas, has been shown to be effective in small, uncontrolled case series of patients with severe or fulminant colitis not responding to standard therapy (50). The cost per day with standard dosing (125 mg 4 times daily) is approximately $70 as compared with $2 with metronidazole. Studies have shown that a regimen of 125-mg oral vancomycin administered four times daily (current standard regimen) is as effective as 500 mg four times a day (older standard) (51). Metronidazole, as opposed to oral vancomycin, is virtually 100% absorbed in the small bowel and reaches the colon through biliary excretion and increased exudation across the intestinal mucosa during diarrhea (52). In healthy volunteers without diarrhea, oral and intravenously administered metronidazole achieve low fecal concentrations but usually exceeds the C. Side effects of metronidazole include dose-dependent peripheral neuropathy, nausea, and metallic taste. Metronidazole is typically dosed orally at 500 mg three times daily or 250 mg four times daily. First, it must be emphasized that treatment is not indicated in patients who are asymptomatic even with a positive stool toxin assay. Mild to Moderate Disease For very mild disease, discontinuation of the inducing agent may be sufficient therapy and no further antibiotic therapy needed. Current guidelines recommend oral metronidazole (500 mg 3 times daily or 250 mg 4 times daily) for initial treatment (Table 3). Metronidazole is favored over oral vancomycin in mild to moderate cases due to its lower cost and good efficacy. Empiric therapy is appropriate if clinical suspicion is high and the initial diagnostic assay is pending or negative. One study showed increased mortality among patients who had an initial false-negative toxin (40). The recommended dose for severe disease is 125-mg oral vancomycin four times daily. Response to treatment is generally rapid, with decreased fever within one day and improvement of diarrhea in four to five days. Patients who fail to respond may have alternate diagnoses, lack of compliance, or the inability of drug to reach the colon such as with ileus or megacolon (26). Yet, all studies have shown failures with both metronidazole and vancomycin (*15% failure rates in the randomized controlled trials). Surgery is indicated for patients with peritoneal signs, systemic toxicity, toxic megacolon, perforation, multiorgan failure, or progression of symptoms despite appropriate antimicrobial therapy and Clostridium difficile Infection in Critical Care 283 recommended before serum lactate >5 (54). Select patients with disease clearly limited to the ascending colon have been treated successfully with right hemicolectomy, but intraoperative colonoscopy should be performed to rule out left-sided disease (40). Among patients requiring surgery, mortality rates after colectomy have ranged from 38% to 80% in small series (40). In a study of patients with fulminant colitis requiring colectomy, the need for preoperative vasopressor support significantly predicted postoperative mortality (40). Teicoplanin may be at least as effective as oral vancomycin or metronidazole but is expensive and not available in the United States. Both fusidic acid, also not available in the United States, and bacitracin have been shown to be less effective than vancomycin (54). Anion exchange resins, such as colestiol and cholestyramine, assert their effect on C. The anion exchange resins are not as effective as oral vancomycin and metronidazole and should not be used as the single agents. Resins must be taken at least two hours apart from oral vancomycin since it binds vancomycin as well as toxins. However, in the first of two subsequent phase 3 trials, tolevamer demonstrated significantly worse outcomes compared with standard therapy with oral vancomycin and metronidazole (57). It has wide antibacterial activity and poor absorption, leading to high intraluminal concentrations.

For example discount acticin 30gm fast delivery, concerning a psychic func- tion such as sense-perception 30gm acticin with visa, one might say that its treatment in Hist. The discussion of the sense-organs in Parts of Animals may then be said to be determined by a ‘moriologic’ perspective in which the special sense-organs are considered with a view to their suitability for the exercise of their respective special sense-functions. And finally, Aristotle’s reasons for dealing with particular aspects of sense- perception at one place rather than another may be quite trivial, for example Aristotle on the matter of mind 211 when, in Gen. To continue with the example of sense-perception, there is a discrepancy between his rather formal and abstract enunciations on visual perception in De an. Even if this ‘emanatory’ doctrine is not identical to the view that Aristotle seems to reject in On Sense Perception and On the Soul, it remains unclear how it is to be accom- modated within the ‘canonical’ theory of visual perception expounded in those works. In dealing with these deviations, Aristotle sometimes refers to physical or physiological mechanisms or entities in respect of which it is not quite clear how they fit in the general picture or what part, if any, they play in the normal procedure. Thus in the example of visual perception over great distances, Aristotle does not explain what atmospheric conditions are conducive to the process of the object setting the visual faculty in motion, resulting in successful seeing. Similarly with regard to the ‘type’ of the melancholics18 – one of Aristotle’s favourite examples of deviations in the area of action 15 788 a 34-b 2. As for the relationship between ‘psychology’ and ‘biology’ in Aristotle, it would be interesting to examine the relationship between Gen. One reason for this may be that Aristotle believed his audience to be sufficiently aware of these physical or physiological processes, perhaps be- cause they were part of a medico-physiological tradition which he took for granted,20 or he may not have quite made up his mind on them himself; in both cases, lack of clarity in the texts21 prevents us from seeing how all these brief references to physiological processes fit together and are to be accommodated within the more ‘formal’ account of On the Soul, in which the emphasis is, as I said, on what ensouled beings have in common and in which deviations are rarely considered (although they are occasionally taken into account in passing in that treatise as well, as in De an. However, it would also seem that these discrepancies are, at least partly, the result of a fundamental tension in Aristotle’s application of the concept of ‘nature’ (fÅsiv), that is, what it means for the psychic functions to operate ‘naturally’ (kat‡ fÅsin). On the one hand, there is what we might call his ‘normative’ (or perhaps ‘idealistic’) view of what it naturally means to be a living plant, animal or human being – an approach which dominates in On the Soul and in the Ethics. On the other hand, there is also a more ‘technical’ or perhaps ‘relativistic’ perspective, in which he is concerned with the mechanics of psychic processes and with a natural explanation of the variations that manifest themselves in the actual performance of psychic functions among different living beings (e. Thus from the one perspective he might say that every human being is intelligent by definition, but from the other that not all human beings are equally intelligent, or from the one perspective that all animals have sense- perception by definition, but from the other that not all animals possess all senses. Aristotle on the matter of mind 213 ‘irritable’ people, ‘quick’ and ‘slow’ people, very young, youthful and very old people, people with prominent veins, people with soft flesh vs. And whilst, depending on their effects, these variable factors are mostly to be regarded as disturbing agents impeding the actualisation of the animal’s capacities (or even, on the level of the ‘first actuality’, affecting the basic vital apparatus of the animal, in which case it counts as a ‘deformation’, pephrwm”non), they can also be conducive to a better and fuller development of these capacities. Some of these variations are explained by Aristotle in an entirely ‘mech- anistic’ way without reference to a higher purpose they are said to serve, because they merely represent residual phenomena to be accounted for (material which is typically suitable for works like the Problemata). How- ever, there are also variations which are, or can be, explained teleologically. Thus also in the seemingly mechanical account of the various forms and de- grees of sharpness of sight in Gen. Thus variations that seem to be merely necessary concomitants of other, pur- posive biological structures and processes – and thus seem to be ‘natural’ (kat‡ fÅsin) only in the mechanical sense – can sometimes be accounted for indirectly as being ‘natural’ (kat‡ fÅsin) in a teleological sense as well. This coexistence of two approaches need not be problematic: Aristotle is very much aware of the difference between teleological and mechanical explanations and is convinced of their being, to a very large extent, complementary. One might also say that the principle of ‘naturalness’ (kat‡ fÅsin) is applied by Aristotle at different levels: he does not shrink from saying that even within the category of things happening ‘contrary to nature’ (par‡ fÅsin), such as the occurrence of deviations, deformations and monstrosities, there is such a thing as ‘the natural’ (t¼ kat‡ fÅsin);26 deviations from the natural procedure can nevertheless display regularity, such as, again, the melancholics, who are said to be naturally abnormal. This difficulty is especially urgent with variations in intellectual capacities; for these are explained with a reference to differences in bodily conditions of the individuals concerned, which raises the question of what the bodily conditions for a ‘normal’ operating of the intellect are and how this is to be related to Aristotle’s ‘normative’ view of thinking as an incorporeal process: is the influence of these bodily conditions in deviations to be regarded as ‘interference’ in a process which normally has no physical aspect whatsoever, or is there also such a thing as a ‘normal’ or ‘healthy’ bodily state which acts as a physical substrate to thinking? On the one hand, Aristotle tries to connect his views on what is best for man with what he believes to be man’s natural activity (kat‡ fÅsin). Aristotle on the matter of mind 215 the position of women, or on the natural disposition of the good citizen). Moreover, he also seems to recognise that natural dispositions, though being necessary conditions for the realisation of human moral and intellectual capacities, are not sufficient to provide human beings with virtue and with happiness, but need development, training, and education. There is a tension here between a ‘biological’ and an ‘ethical’, perhaps ‘anthropocentric’ approach to human activity which has been well expressed by Gigon in his discussion of Aristotle’s treatment of the contribution of nature to human happiness in the first chapter of the Eudemian Ethics: ‘In the background lurks the problem (which is nowhere explicitly discussed in the Corpus Aristotelicum as we have it) why nature, which arranges everything for the best, is not capable of securing happiness for all people right from the start. Extremely useful (and deserving to be taken into account much more thoroughly by students of Aristotle’s psychology) are the contributions by Tracy (1969); and by Solmsen (1950), esp. Nor are some German contributions from the nineteenth century to be neglected, such as Baumker (¨ 1877); Neuhauser (¨ 1878a, b); Schmidt (1881); Kampe (1870); Schell (1873). However, such a study would have to take into account the different levels of explanation on which Aristotle is at work in various contexts as well as the types of context in which Aristotle expresses himself on these issues. The following typology of contexts (which does not claim to be exhaustive) would seem helpful: (1) First, there are contexts in which Aristotle explains the bodily struc- tures with a view to their suitability (–pithdei»thv, o«kei»thv) for the fulfilment of the psychic functions in which they are involved, for exam- ple, when he describes the structure of the human hand by reference to the purpose it is intended to serve,35 or man’s upright position with a view to man’s rational nature. Lloyd sum- marises: ‘whenever he is dealing with an instrumental part that is directly concerned with one of the major faculties of the soul identified in the De anima, Aristotle cannot fail to bear in mind precisely that that is the func- tion that the part serves, and he will indeed see the activities in question as the final causes of the parts’. Thus in his explanations of memory, recollection, sleeping and dreaming, Aristotle goes into great (though not always clear) physiological detail to describe the bodily parts involved in these ‘psychic’ activities and the physical processes that accom- pany them (e. Aristotle on the matter of mind 217 (3) Thirdly, there are contexts in which Aristotle is giving a physiological explanation of variations in the distribution of psychic capacities or in their performance among various species of animals or types within one species – variations which, as I said, can be either purposive or without a purpose.

When I began to write this book discount 30gm acticin visa, I imagined that I would be talking to you order 30gm acticin with mastercard, the individual reader, as I would one of my patients. Yet for many people, a deeper understanding is important because it puts a reason behind the recommendations. Many people jump on and off healthful practices because they don’t really understand how health works; they are very frustrated and looking for a “quick fix” that never really works in the long run. I strongly believe that if you understand why we are unhealthy as individuals, a country, and now the world, and understand the “how to” of these 9 Simple Steps to Optimal Health, you will be able to stay on a positive, health-promoting lifestyle. The truth is that good health is much simpler than investing in the stock market, running a business, or being a working mother with three chil- dren. You will experience an immediate return if you just keep practicing these principles 80 to 90 percent of the time. Having a healthy workforce and a strong economy can only enhance our security as a nation. Leading the World to Good Health With this example of positively changing the health of the Unit- ed States, and thereby improving our economy, work productiv- - xxxi - staying healthy in the fast lane ity, quality of life, and environment, we (the United States) can be the world leader we should be. In this free market system full of positive, health-promoting entrepreneurship, in conjunction with “lean” government, we can show other countries how to help their own people be healthy and productive and reduce this needless toll of suffering and cost that comes from chronic diseases related to the modern lifestyle. The message in this book is not just meant for the individual or even for my own country; it is meant for the whole world. Even in the days before she passed, she never lost her positive spirit or her will to succeed. One of my favorite memories of her is huffing and puffing, attached to her oxygen tubing and using her walker as she slowly crossed my dance floor, cheering herself on. The nutrition and exercise data are there; the ex- amples of successfully aging cultures living with minimal chronic disease are there. Chronic diseases, such as heart disease, cancer, diabetes, high blood pressure, stroke, arthritis, bone loss, and degenerative neu- rologic and ocular diseases are increasing worldwide as the world urbanizes. These chronic conditions account for 70 percent of all deaths in the United States and 60 percent of all deaths worldwide. These chronic conditions can be significantly reduced, their progression slowed, and some virtually eliminated by lifestyle changes involv- ing diet, increased physical activity, and positive mental condition- ing. Pharmaceutical approaches can only treat symptoms but do not correct the underlying causes of these conditions. As countries urbanize (move from an agrarian lifestyle to cit- ies) and as manufacturing, transportation, and marketing improve, more processed foods, which are high in caloric density and low in nutrient density, are consumed. This is why the world has seen an - 3 - staying healthy in the fast lane increase in “empty” calorie consumption, even in countries where food shortages exist. Also, individuals in urban areas are gener- ally less physically active and have a more chronically stressful lifestyle. Individual calorie availability has increased between four and five hundred calories per day in the United States over the last cen- tury. Therefore, we have been consuming almost a pound extra in calories per week over the last forty years. This is why the United States has an epidemic of overweight issues and associated diseases. The major reasons for this calorie increase in the United States come from five major dietary changes and patterns over the last century (see illustrations at end of chapter 1): 1. A continued increase in total meat consumption, with red meat consumption decreasing and poultry consumption in- creasing. A continued, steady increase in calorie sweeteners, more so from corn sweeteners now than the cane and beet sugars of the past. An increase in grains since the early 1970s, of which 85 percent are refined grains, with “sweet-fat” calories added. Thus fruit and vegetable prices have increased by about 50 percent from 1982 to 2008, with much less marketing of their health benefits to the public. The other - 4 - urbanization, the modern lifestyle, and chronic disease food components of the processed food industry that added extra calories and reduced protective micronutrients to our foods have actually had a reduction in real costs. Adjusted for inflation, prices decreased by 10 percent for fats and oils, 15 percent for sugars and sweets, and 34 percent for carbonated soft drinks. The culmination of these five dietary patterns over the last cen- tury has led to an unhealthy and devastating food intake pattern in the United States, in which 12 percent of the calorie intake is from plant foods (up to half of which may be processed), 25 percent animal foods (almost all of which is factory farmed, not free-range drug-free animals), and 63 percent processed foods containing added fats, oils, sugars, and refined grains. Consequently, chronic diseases are occurring in developing countries at alarming rates as their traditional diets change to more urbanized or “Westernized” diets and daily physi- cal activity is reduced, similar to developed countries. A reduction in excess calorie consumption with an increase in nutrient-dense foods would lead to weight normalization and significantly reduce the incidence of many chronic diseases. This would dramatically reduce healthcare costs and human suffering, while increasing work productivity. Nutrient-dense foods have many health promoting compounds (antioxidants, vitamins, minerals, phytochemicals, fiber, etc. Now is the time for this approach because: • Healthcare in the United States and around the world needs real reform from the current disease-care models to pre- vention-oriented models.

Steroids may be detrimental and available antivirals have not proven of benefit (107) purchase 30gm acticin with amex. Incubation period: Incubation periods for most pathogens are from 7 to 14 days buy acticin 30gm free shipping, with variousranges(Lassafever:5–21days;RiftValleyfever:2–6days;Crim ean-Congo hemorrhagic fever after tick bite: 1–3 days; contact with contaminated blood: 5–6 days); Hantavirus hemorrhagic fever with renal syndrome: 2 to 3 weeks (range: 2 days–2 months); Hantavirus pulmonary syndrome (Sin Nombre virus): 1 to 2 weeks (range: 1–4 weeks); Ebola virus: 4 to 10 days (range 2–21 days); Marburg virus: 3 to 10 days; dengue hemorrhagic fever: 2 to 5 days; yellow fever: 3 to 6 days; Kyasanur forest hemorrhagic fever: 3 to 8 days; Omsk hemorrhagic fever: 3 to 8 days; Alkhumra hemorrhagic fever: not determined. These incubation periods are documented for the pathogens’ traditional modes of transmission (mosquito tick bite, direct contact with infected animals or contaminated blood, or aerosolized rodent excreta). Contagious period: Patients should be considered contagious throughout the illness. Clinical disease: Most diseases present with several days of nonspecific illness followed by hypotension, petechiae in the soft palate, axilla, and gingiva. Patients with Lassa fever develop conjunctival injection, pharyngitis (with white and yellow exudates), nausea, vomiting, and abdominal pain. Severely ill patients have facial and laryngeal edema, cyanosis, bleeding, and shock. Livestock affected by Rift Valley fever virus commonly abort and have 10% to 30% mortality. There is 1% mortality in humans with 10% of patients developing retinal disease one to three weeks after their febrile illness. Patients with Crimean-Congo hemorrhagic fever present with sudden onset of fever, chills, headache, dizziness, neck pain, and myalgia. Some patients develop nausea, vomiting, diarrhea, flushing, hemorrhage, and gastrointestinal bleeding. Patients with Hantavirus hemorrhagic fever with renal syndrome go through five phases of illness: (i) febrile (flu-like illness, back pain, retroperitoneal edema, flushing, conjunctival, and 476 Cleri et al. Patients typically have thrombocytopenia, leukocytosis, hemoconcentration, abnormal clotting profile, and proteinuria. Hantavirus pulmonary syndrome presents with a prodromal stage (three to five days— range: 1–10 days) followed by a sudden onset of fever, myalgia, malaise, chills, anorexia, and headache. Patients go on to develop prostration, nausea, vomiting, abdominal pain, and diarrhea. This progresses to cardiopulmonary compromise with a nonproductive cough, tachypnea, fever, mild hypotension, and hypoxia. Chest X rays are initially normal but progress to pulmonary edema and acute respiratory distress syndrome. Patients have thrombocytopenia, leukocytosis, elevated partial thromboplastin times, and serum lactic acid and lactate dehydrogenase. Patients infected with Ebola virus have a sudden onset of fever, headache, myalgia, abdominal pain, diarrhea, pharyngitis, herpetic lesions of the mouth and pharynx, conjunctival injection, and bleeding from the gums. The initial faint maculopapular rash that may be missed in dark-skinned individuals evolves into petechiae, ecchymosis, and bleeding from venepuncture sites and mucosa. Marburg hemorrhagic fever is similar with a sudden onset of symptoms progressing to multiorgan failure and hemorrhagic fever syndrome. Half of the patients with dengue hemorrhagic fever and classical dengue have a transient rash. Two to five days after classical dengue fever, patients go into shock, develop hepatomegaly, liver enzyme elevations, and hemorrhagic manifestations. Ribavirin has been used for prophylaxis and treatment of Lassa fever, Sabia virus hemorrhagic fever, Argentine hemorrhagic fever, Bolivian hemorrhagic fever, Rift Valley fever, Crimean-Congo hemorrhagic fever, and Venezuelan hemorrhagic fever. Ribavirin has been used to treat Hantavirus hemorrhagic fever with renal syndrome but does not appear effective in treating Hantavirus pulmonary syndrome. There is no specific therapy for yellow fever, Ebola, or Marburg virus infections. The intravenous regimen recommended for the viral hemorrhagic fevers is as follows: 2 g loading dose, followed by 1 g every six hours for four days, followed by 0. Another intravenous regimen: 30 mg/kg loading dose, followed by 15 mg/kg every six hours for four days; followed by 7. Oral regimen: 2 g loading dose, followed by 4 g/day in four divided doses for four days; followed by 2 g/day for six days. Aerosolized virus is inactivated in 48 hours, but may remain viable in house dust for up to two years. Exposure to contaminated materials, clothing, and blankets can spread infection, and although rare, infection over long distances has been reported. Contagious period: Patients are not contagious during the incubation period but one to two days before the onset of symptoms or when the oral enanthema appears (24 hours prior to the rash). Viral shedding is greatest during the first 10 days of the rash, but persists until all scabs and crusts are shed. Bioterrorism Infections in Critical Care 477 Clinical disease: The prodrome begins with the sudden onset of fever, chills, back pain, headache, malaise, and sometimes nausea, vomiting, abdominal pain, and confusion. The typical patient develops a centrifugal rash two to three days after the onset of symptoms or very quickly after the enanthem. Early lesions are shotty and within 24 to 48 hours become vesicular then pustular.

This will be an important contribution to genomics-based health care and personalized medicine 30gm acticin with amex. Data will be submitted in a form that protects the privacy and confidentiality of research participants acticin 30 gm discount. The data will be made freely available to all approved researchers to accelerate their studies. Data will be released in a manner that preserves the privacy and confiden- tiality of research participants. A thousand persons will have their genomes sequenced in an ambitious 3-year project that will create the most comprehensive catalogue so far of human genetic variation. These volunteers have already been recruited from Africa, Asia, America, and Europe. The donors are anonymous and will not have any of their medical informa- tion collected because the project is developing a basic resource to provide information on genetic variation. The goal of the 1000 Genomes Project is to uncover the genetic variants that are present at a frequency of 1 % or more in the human genome. Three 1000 Genomes pilot projects, which began in 2008 aim to achieve low coverage of 180 individuals, high coverage of two parent-offspring trios, and targeted sequencing of 1,000 genes in approximately 1,000 individuals, are nearing completion. Those efforts seem to be generating high-quality data and have already uncovered new genetic variants. So far, the 1000 Genomes Project has Universal Free E-Book Store 696 24 Future of Personalized Medicine generated 3. In 2009, the project is expected to up that dramati- cally, producing a petabyte of data. Beyond the direct implications for the 1000 Genomes Project, the effort has spurred researchers to pioneer and evaluate methods that benefit other research efforts as well. There a need, however, for developing shared data formats for different stages of the analysis. In the absence of standard formats or a clear framework for such analysis, efforts to decipher the genetic information would be delayed. Consequently, team members are working to develop draft formats to aid this analysis. A better understanding of the genetic causes of longevity could have a major impact on the Indian Government’s healthcare bud- get and drug companies’ marketing efforts. The use of Affymetrix technology will enable researchers to correlate genes with longevity, as well as neurodegenerative condi- tions, breast cancer, diabetes and other complex diseases that affect the Parsi com- munity. The Parsi community was selected because of its longevity and its relatively genetically homogeneous population. This project takes a systems biology approach that encompasses not only genotyping but also expression profiling and transcrip- tomics. The genotyping phase of the project, which began in 2007, consisted of 10,000 samples in the first year. By the middle of 2008, the team had performed expression profiling and transcript mapping experiments across a subset of the sam- ples.. Data confidentiality is being maintained as in accor- dance with the Indian Council of Medical Research guidelines. Translational Science and Personalized Medicine Translational science deals with transfer of technologies from preclinical research into clinical application. There is a need for a comprehensive research agenda to move human genome discoveries into health practice in a way that maxi- mizes health benefits and minimizes harm to individuals and populations. A frame- work has been presented for the continuum of multidisciplinary translation research that builds on previous characterization efforts in genomics and other areas in health care and prevention (Khoury et al. The continuum includes four phases of trans- lation research that revolve around the development of evidence-based guidelines: • Phase 1 translation (T1) research seeks to move a basic genome-based discovery into a candidate health application (e. Because the development of evidence-based guidelines is a moving target, the types of translation research can overlap and provide feedback loops to allow inte- gration of new knowledge. Although it is difficult to quantify genomics research is T1, no more than 3 % of published research focuses on T2 and beyond. With continued advances in genomic applications, however, the full continuum of translation research needs adequate support to realize the promise of genomics for human health. Eventually, researchers hope to determine whether participating in personal genomic testing spurs individuals to make beneficial lifestyle changes such as improving their diet and exercise regimes. The team plans to track participants’ lifestyle changes using self-reported health questionnaires. Participants will complete the questionnaires at baseline and again 3 and 6 months after receiving the personal genetic test, which is designed to assess each individuals’ genetic propensity for more than 20 health conditions, including diabetes, hearts disease, and some cancers. Those enrolled will also be asked to participate in surveys periodically over the next 20 years. The results will be compiled in a database hosted by the Scripps Genomic Medicine program.
