Health Care Problem (health + care_problem)
Selected AbstractsIncontinence: prevalence, management, staff knowledge and professional practice environment in rehabilitation unitsINTERNATIONAL JOURNAL OF OLDER PEOPLE NURSING, Issue 1 2009Geraldine McCarthy MSc Background., Bladder and bowel incontinence is a major health care problem, which adversely affects the lives of many individuals living at home or in health service facilities. Current approaches to continence care emphasize comfort, safety and reduction of risk, rather than detailed individualized assessment and management. The literature illustrates a gap between evidence and actual practice and emphasizes the context of care as being a key element for successful implementation of evidence based practice. Aims., To identify prevalence of bowel and bladder incontinence and its management, investigate continence knowledge and describe the professional practice environment within a rehabilitation unit for older people. Method., An integrated evaluation of continence prevalence, staff knowledge and the work environment was adopted. Results., Findings revealed a high incidence of incontinence (60% urinary, 3% faecal, 37% mixed) a lack of specific continence assessment and specific rationale for treatment decisions or continuation of care. The focus was on continence containment rather than on proactive management. Staff demonstrated a reasonable knowledge of incontinence causation and treatment as measured by the staff knowledge audit. The evaluation of the work environment indicated a low to moderate perception of control over practice (2.39), autonomy in practice (2.87), nurse doctor relationship (2.67) and organizational support (2.67). [source] Health Care in Rural TexasPOLICY STUDIES JOURNAL, Issue 1 2001William DeSoto The purpose of this article is to assess the quality of health and health care services available to rural Texans. Specifically, we seek to answer two related questions. First, do people living in rural areas of Texas generally suffer from poorer health than people living in urban Texas? One undoubtedly would think so, given frequent references to the low quality of personal services in general for rural America. Moreover, the persistence of the congressional Rural Health Care Caucus over the past two decades points to a rural health care crisis. Second, to what extent are these differences in health conditions explained by differences in access to health care enjoyed by people living in the two different regions? Access certainly appears to be the problem alluded to above. Rural people apparently lack physician care. In addition to providing answers to these questions, we also examine the difference in the health conditions and access to care enjoyed by minority and non-minority rural Texans. Is this a part of the rural health care problem given the high incidence of non-whites in rural Texas? If so this may be minority rather than rural neglect. We briefly conclude the article with some recommendations for improving the problems we identify.

Because this disease develops slowly, early detection and intervention can greatly affect ultimate outcome. Celecoxib is a cyclooxygenase-2 inhibitor with significantly less toxicity. This study investigated the possibility of using it for chemoprevention of oral cancer at the early stages. Study Design: Randomized animal study. Methods: Dysplastic lesions were induced in the buccal pouches of 47 hamsters by a 5 week painting of 9,10-dimethl-1,2-benzanthrancene (DMBA). Basal diets or diets containing 500 or 1,500 ppm of Celecoxib were orally given for 7 weeks. The T50 (50% incidence; i.e., the time to appearance of tumors in 50% of the hamsters) was observed, and volume of tumors was measured on day 1, 9, 19, 28, 35, and 48 with the Celecoxib treatment. Results: The T50 was 9, 19, and 28 days with the treatment in the control group, in the 500 ppm group, and in the 1,500 ppm group, respectively. It indicated that the Celecoxib treatment could delay progression of early lesion. The tumor measurement showed that this treatment was also effective in delaying tumor growth in both treatment groups. There was a difference in the treatment efficacy between the 500 ppm and 1,500 ppm of Celecoxib, indicating a dose-dependent efficacy. Conclusions: Celecoxib is effective in delaying onset of early lesions induced by DMBA and in slowing growth of the tumors in hamster cheek pouches during the postinitiation stage. Its treatment efficacy appears to be dose dependent. [source] Beta-lactam antibiotics: from antibiosis to resistance and bacteriologyAPMIS, Issue 1 2010KOK-FAI KONG Kong K-F, Schneper L, Mathee K. Beta-lactam antibiotics: from antibiosis to resistance and bacteriology. APMIS 2010; 118: 1,36. This review focuses on the era of antibiosis that led to a better understanding of bacterial morphology, in particular the cell wall component peptidoglycan. This is an effort to take readers on a tour de force from the concept of antibiosis, to the serendipity of antibiotics, evolution of beta-lactam development, and the molecular biology of antibiotic resistance. These areas of research have culminated in a deeper understanding of microbiology, particularly in the area of bacterial cell wall synthesis and recycling. In spite of this knowledge, which has enabled design of new even more effective therapeutics to combat bacterial infection and has provided new research tools, antibiotic resistance remains a worldwide health care problem.
