Alternative-Care Providers Alternative-care providers would also beneft from participating in educational programs about viral hepatitis. Lack of knowledge and awareness about hepatitis B and hepatitis C in the community often leads to misinformation, missing of opportunities for prevention and treatment, and stigmatization of infected populations. Once infected, they frequently are unaware of their infection and so run the risk of unknowingly infecting others and of not receiving appropriate medical management. Although there have been no large-scale, population- based, controlled studies of community knowledge about hepatitis B and hepatitis C, all published surveys have shown that knowledge about these diseases is sparse. A number of studies have assessed awareness and knowledge about hepatitis B Copyright © National Academy of Sciences. Hepatitis and Liver Cancer: A National Strategy for Prevention and Control of Hepatitis B and C http://www. For example, among Vietnamese Americans, about 64% had never heard of the hepatitis B vaccine (Ma et al. Among Chinese Americans, fewer than half had been tested or vaccinated (Taylor et al. The committee was unable to fnd studies that looked at hepatitis B awareness among other foreign-born immigrants from highly endemic re- gions such as sub-Saharan Africa, the Middle East, and Eastern European nations (see Box 3-1). For example, New York City has translated its hepatitis B educational materials into Chinese, Korean, Spanish, and French (New York Department of Health and Mental Hygiene, 2008). Hepatitis and Liver Cancer: A National Strategy for Prevention and Control of Hepatitis B and C http://www. A 1990 study found that 68% of men who have sex with men and are patients at a community health center reported that they were aware of the vaccine, and 25% of those who knew about it had been vac- cinated (McCusker et al. Most of the participants who knew about the hepatitis B vaccine had learned about it from newspapers targeting the gay population (64%); a minority had learned about it from health-care providers (44%), friends (37%), and brochures from health-care facilities or gay organizations (36%). A 1999 study had similar fndings: 33% of the participants were unaware of the hepatitis B vaccine, and 63% had not been tested for hepatitis B; of those who were aware of the vaccine, only 22% had received the full vaccine series (Neighbors et al. Stigma For many people born outside the United States, a cultural stigma is attached to a diagnosis of chronic hepatitis B. For example, in China, there is pervasive discrimination against people who are chronically infected with hepatitis B, who are frequently expelled from schools, fred from jobs, and shunned by other community members despite the recent passage of national antidiscrimination laws (China Digital Times, 2009). In a 2007 survey covering 10 major cities in China, hepatitis B was cited as one of the top three reasons for job discrimination (China Daily, 2007). Given the deeply ingrained stigma of hepatitis B in some endemic countries, it is not surprising that many immigrants remain reluctant to undergo testing and seek medical attention for a positive test result even after moving to the United States.

Among 924 unvacci- nated participants, nearly all received the frst dose of hepatitis B vaccine, 89% received the second, and 79% completed the three-dose series. The Asian American Hepatitis B Program, a collaboration of community groups and academic and community health centers in New York City, provides hepatitis B screening, vaccination, and treatment. The Jade Ribbon Campaign is a program focused on reducing the nationwide health disparity in hepatitis B. This model has been adapted by a number of cities around the country (Chang et al.

Polypeptide chains do not exist as long straight chains order lamictal 25 mg otc medicine x topol 2015, nor do they curl up into random shapes order 200mg lamictal free shipping medicine quizlet, but instead fold into a definite three- dimensional structure. The chains of amino acids tend to coil into helices (secondary structure) due to hydrogen bonding between side chain residues, and sections of the helices may fold on each other due to hydrophobic interactions between nonpolar side chains and, in some proteins, to disulfide bonds so that the overall molecule might be globular or rod-like (tertiary structure). Their exact shape depends on their function and for some proteins, their interaction with other molecules (quaternary structure). The most important aspect of a protein from a nutritional point of view is its amino acid composition, but the protein’s structure may also influ- ence its digestibility. Some proteins, such as keratin, are highly insoluble in water and hence are resistant to digestion, while highly glycosylated proteins, such as the intestinal mucins, are resistant to attack by the proteolytic enzymes of the intestine. Amino Acids The amino acids that are incorporated into mammalian protein are α-amino acids, with the exception of proline, which is an α-imino acid. This means that they have a carboxyl group, an amino nitrogen group, and a side chain attached to a central α-carbon (Figure 10-1). Functional differences among the amino acids lie in the structure of their side chains. In addition to differences in size, these side groups carry different charges at physiological pH (e. These side chains have an important bearing on the ways in which the higher orders of protein structure are stabilized and are intimate parts of many other aspects of protein function. Attractions between positive and negative charges pull different parts of the molecule together. Hydrophobic groups tend to cluster together in the center of globular proteins, while hydrophilic groups remain in contact with water on the periphery. The ease with which the sulfhydryl group in cysteine forms a disulfide bond with the sulfhydryl group of another cysteine in a polypeptide chain is an important factor in the stabilization of folded structures within the poly- peptide and is a crucial element in the formation of inter-polypeptide bonds. The hydroxyl and amide groups of amino acids provide the sites for the attachment of the complex oligosaccharide side chains that are a feature of many mammalian proteins such as lactase, sucrase, and the mucins. Histidine and amino acids with the carboxyl side chains (glutamic acid and aspartic acid) are critical features in ion-binding proteins, such as the calcium-binding proteins (e. Some amino acids in protein only achieve their final structure after their precursors have been incorporated into the polypeptide. The former hydroxylated amino acids are critical parts of the cross-linking of collagen chains that lead to rigid and stable structures. Nutritional and Metabolic Classification of Amino Acids Older views of the nutritional classification of amino acids categorized them into two groups: indispensable (essential) and dispensable (non- essential). The nine indispensable amino acids (Table 10-1) are those that have carbon skeletons that cannot be synthesized to meet body needs from simpler molecules in animals, and therefore must be provided in the diet. Although the classification of the indispensable amino acids and their assignment into a single category has been maintained in this report, the definition of dispensable amino acids has become blurred as more infor- mation on the intermediary metabolism and nutritional characteristics of these compounds has accumulated. Laidlaw and Kopple (1987) divided dispensable amino acids into two classes: truly dispensable and condition- ally indispensable. In addition, six other amino acids, including cysteine and tyrosine, are conditionally indispens- able as they are synthesized from other amino acids or their synthesis is limited under special pathophysiological conditions (Chipponi et al. This is even more of an issue in the neonate where it has been suggested that only alanine, aspartate, glutamate, serine, and probably asparagine are truly dietarily dispensable (Pencharz et al. The term conditionally indispensable recognizes the fact that under most normal conditions the body can synthesize these amino acids to meet metabolic needs. However, there may be certain physiological circum- stances: prematurity in the young infant where there is an inadequate rate at which cysteine can be produced from methionine; the newborn, where enzymes that are involved in quite complex synthetic pathways may be present in inadequate amounts as in the case of arginine (Brunton et al. The cells of the small intestine become important sites of conditionally indispensable amino acid, synthesis, with some amino acids (e. However, the quantita- tive requirement levels for conditionally indispensable amino acids have not been determined and these, presumably, vary greatly according to the specific condition. There now appears to be a requirement for preformed α-amino nitrogen in the form of glutamate, alanine, or aspartate, for example (Katagiri and Nakamura, 2002). However, there are now good theoretical reasons to conclude that this is not likely in the human (Katagiri and Nakamura, 2002). The mixture of dispensable and conditionally indispensable amino acids as supplied by food proteins at adequate intakes of total nitrogen will assure that both the nitrogen and specific amino acid needs are met. Nearly half of this protein (about 43 percent) is present as skeletal muscle, while other structural tissues such as skin and blood each contain approximately 15 percent of the total protein (Lentner, 1981).

The aim economic importance of treatment of preventive health care should be technologies, particularly for those the reduction of untimely deaths in illnesses that primarily affect poorer relatively young people, but the fear people in poorer countries [18]. This of accusations of ageism in health care has meant a shift of attention from means that doctors are encouraged the sick to the well and from the poor to go on prescribing preventive to the rich [19]. This effect of global pharmaceuticals to people well into markets requires a response in the their late eighties and nineties [15].
