摘要:

Discovery of genes associated with clinical disorders Increases the ability of clinicians to more accurately assess risk for their clients to develop or to be carriers of certain health problems. Estimating these risks has become more precise with the addition of genetic testing. The process of client assessment and considerations associated with genetic testing for cystic fibrosis and one form of colon cancer (familial adenomatous polyposis) are presented in a case study format. Ethical considerations in the use of genetic testing include protection of privacy, protection from coercion, and assuring client understanding of implications of test results. Practitioner responsibilities also include educating clients regarding benefits and limitations of testing, collaborating with genetic counseling resources, and monitoring the client for potential adverse outcomes of testing.

摘要:

Free radicals (FRs) are reactive chemical species that can damage or destroy biological molecules and have the potential for causing serious tissue and organ damage. Because of evidence suggesting that they are involved in the pathophysiology of a wide spectrum of human disorders, FRs have recently been the subject of considerable interest. While some popularized accounts depict FRs as always being destructive, essential physiological functions, including prostaglandin biosynthesis and phagoctye activity, depend upon them. It is only when FR reactions are uncontrolled that they are likely to be destructive. This article, based on citations from peer-reviewed biomedical literature, discusses some of the roles FRs play in essential physiological processes and their potential for inducing pathological changes. Also discussed are factors that add to body burdens of FRs and various antioxidant control mechanisms. The relationship of diet to FR pathology is emphasized because of evidence suggesting its importance in the prevention of chronic degenerative disorders including cardiovascular disease and cancer. The health benefits accruing from appropriate application of FR research are likely to be substantial. Accordingly, it is important for all health care practitioners to be aware of new developments in this area.

摘要:

As the use of oxygen therapy increases, primary care providers must become familiar with numerous aspects of home oxygen therapy, and they need to identify those patients who will benefit from this therapy. A number of oxygen systems are available today. A few helpful hints aid in providing effective, efficient, quality care to these patients in the primary care clinic. It is most important that health care providers know what is required to recertify a patient for oxygen therapy and how to properly complete the Health Care Financing Administration Form 484. Periodic evaluations are required by insurance companies and Medicare. This article discusses the identification of patients who will benefit from home oxygen therapy, administration, and recertification for home oxygen therapy.
