C Rundel, Genes, aging, and the future of longevity. A delightful essay on some issues of aging, written by a Caltech undergraduate as part of a science writing class -- and then published in the Caltech magazine. The article discusses some genes that are known to affect aging in simple model organisms, and even a drug which seems to extend the life of fruit flies. An intriguing result has recently been published: A team at Scripps Research Institute La Jolla, California has engineered mice to have a slightly lower core body temperature by about 0. How did they lower the body temperature?
Rare Disease Case Study: Familial Amyloidosis
Lemierre's syndrome: One rare disease-Two case studies
A case—control study also known as case—referent study is a type of observational study in which two existing groups differing in outcome are identified and compared on the basis of some supposed causal attribute. A case—control study produces only an odds ratio, which is an inferior measure of strength of association compared to relative risk. The case—control is a type of epidemiological observational study. An observational study is a study in which subjects are not randomized to the exposed or unexposed groups, rather the subjects are observed in order to determine both their exposure and their outcome status and the exposure status is thus not determined by the researcher. Porta's Dictionary of Epidemiology defines the case—control study as: an observational epidemiological study of persons with the disease or another outcome variable of interest and a suitable control group of persons without the disease comparison group, reference group. For example, in a study trying to show that people who smoke the attribute are more likely to be diagnosed with lung cancer the outcome , the cases would be persons with lung cancer, the controls would be persons without lung cancer not necessarily healthy , and some of each group would be smokers. If a larger proportion of the cases smoke than the controls, that suggests, but does not conclusively show, that the hypothesis is valid.
Natural History Studies in Rare Diseases and Genetic Biomarkers
All health professionals need to be aware of rare disease and ensure patients receive prompt diagnosis, information and ongoing support. This six-part series on rare diseases aims to increase awareness and offer advice on how nurses can help patients. Part 1 uses a case study to illustrate the complexity of caring for people with rare diseases and provides pointers on how the care of this patient group can be improved. Nursing Times ; 45,
When there is the assignment connected with the case study writing, the student should remember that the paper is expected to have the strict order, valid arguments, wise solutions and professional methodology. Many students can find a case study on a disease difficult, but of one reads the case study writing tips below, he will manage to construct an adequate paper which would impress every professor. All these facts will be necessary for the right diagnosis and research of the cause and effect of the disease.
