...virus (HCV) is a major public health problem and is the most common liver disease among hemodialysis (HD) patients. The seroprevalence of HCV infection among HD ranged from 1.9% to 80% in reports published since 1999. The main risk factor for HCV acquisition in HD patients seems the length of time on HD. Phylogenetic analysis of HCV viral isolates has suggested nosocomial patient-to-patient transmission of HCV infection among HD patients. Lack of strict adherence to universal precautions by staff and sharing of articles such as multidose drugs might be the main mode of nosocomial HCV spread among HD patients. Currently, there are several dilemmas on the management of these patients: should HCV-RNA testing be included in the routine screening of HD population for HCV infection?; does periodic serum alanine aminotransferase testing have a role in screening HD patients for HCV infection?; can dialysis really 'save' the liver of HCV-infected HD patients?; should HCV-infected subjects be isolated and dialyzed by segregated machines?; is there any difference in treating HD and non-HD HCV-infected subjects? This article gathers the present evidence to address these issues and to demonstrate the current worldwide magnitude of HCV in HD population. Keywords: Hepatitis C Virus, Hemodialysis, Genotype...

...Communicable Disease Outbreak Analysis Evelyn Sutton Western Governor's University Communicable Disease Outbreak Analysis There are many diseases that have become a thing of the past due to vaccines that are routinely given during infancy and early childhood in the United States. These diseases still exist but we just see it very rarely now. When a person is diagnosed with one of these communicable diseases in the United States, it is reported to the Department of Health and Environmental Control and the Centers of Disease Control so it can be investigated further. This is required so they can monitor for any outbreaks that may occur and find the origin of where and how it was contracted. Any case of the measles that is diagnosed in the United States is said to have come over through international travel in some way. Measles Outbreak In December of 2014, during the holiday season, a measles outbreak was beginning at two adjacent Disneyland locations in California. It was first discovered on January 5, 2015, when the California Department of Public Health was notified about an eleven-year-old child who was unvaccinated for the measles and hospitalized with a rash onset on December 28, 2014 (Clemmons, Gastanaduy, Fiebelkorn, Redd, & Wallace, 2015). Just two days later, a total of seven cases of measles had been discovered. It started out with seven cases and by the time the outbreak was declared over in April of 2015, there had been a total of 136 confirmed cases...

...Unit II: Genetics Brief Overview Reading: Chapters 3, 4, 9-12, 14 (Note: you have reviewed much of this already) The earth is teeming with living things. We can easily see some of the larger organisms—trees, grass, flowers, weeds, cats, fish, squirrels, dogs, insects, spiders, snails, mushrooms, lichens. Other organisms are everywhere, in the air, in water, soil and on our skin, but are too small to see with the naked eye—bacteria, viruses, protists (single celled eukaryotes such as amoebae), and tiny plants and animals. Life is remarkable in its complexity and diversity, and yet it all boils down to a very simple idea—the instructions for making all this life are written in nucleic acids, usually DNA. Most organisms have a set of DNA that contains the instructions for making that creature. This DNA contains four “letters” in which these instructions are written—A, T, G, and C. The only difference between the code for a dog and the code for a geranium is in the order of those letters in the code. If you took the DNA from a human and rearranged the letters in the right way, you could produce an oak tree—arrange them slightly differently and you would have a bumble bee—arrange them again and you would have the instructions for making a bacterium. Acting through more than two billion years, the process of evolution has taken one basic idea—a molecular code that uses four letters—and used it over and over, in millions of combinations to produce a dazzling array of life forms...

EFSA Scientific Report (2009) 231, 1-107 © European Food Safety Authority, 2009 Review of the potential health impact of β-casomorphins and related peptides SUMMARY Proteins are a very diverse family of large organic compounds involved in many important biological processes. Following their enzymatic hydrolysis during food processing or digestion, proteins may release fragments from their primary amino acid sequence. These fragments are called peptides, and many of them are known to be physiologically active. The possible beneficial effects of bioactive peptides have attracted increasing interest in recent years. On the other hand, there are also reports suggesting that some food-derived peptides might adversely affect human health. Among these, β-casomorphin-7 (BCM7), a peptide sequence present in the milk protein β-casein, has been suggested to...

Patient-driven health care can be characterized as having an increased level of information flow, transparency, customization, collaboration and patient choice and responsibility-taking, as well as quantitative, predictive and preventive aspects. The potential exists to both improve traditional health care systems and expand the concept of health care though new services. This paper examines three categories of novel health services: health social networks, consumer personalized medicine and quantified self-tracking.

The learners have also discovered that cells divide to produce new cells by mitosis and meiosis. They have understood that meiosis is an early step in sexual reproduction that leads to variation. Students have been introduced to genetics to be able to appreciate evolutionary differences among species. Learners have also found out that biodiversity is the collective variety of species living in an ecosystem, and by studying the ecosystem; they have come across the various cycling of materials and energy transformation. DRAFT April 29, 2014 All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer...

...Outline The overall objective of this research paper is to identify and address those aspects of alcoholism, which contribute to it as a medical disease. True, alcoholism has many ramifications for society as well as the economy, but the focus of this paper shall be, for the most part, on the medical aspects. In the way of background, alcoholism refers to the drinking of alcoholic beverages to such a degree that major aspects of the individual’s life -such as work, school, family relationships or personal SAFETY AND HEALTH, above all, are seriously and repeatedly interfered with. Alcoholism is considered a disease, meaning that it follows a characteristic course with known physical, psychological, and social systems. The alcoholic continues to consume alcohol despite the destructive consequences. Alcoholism is serious, progressive, and irreversible. If not treated, it can be fatal. It is generally thought that once the disease has developed, the alcoholic will not drink normally again. An alcoholic who abstains from drinking, however, can regain control over the aspects of life with which ALCOHOL interfered. The alcoholic is then said to be “recovering” not “cured” of the disease. It is important to note that the particular symptoms and pattern of DRINKING PROBLEMS may vary with the individual. ALCOHOLISM is, therefore, a very complex disorder, and it is this very complexity which has led some recent researchers to question the accuracy of the disease concept of alcoholism...
