In Part Two of the paper a model forcurriculum development is proposed which derives from the teaching experience of the authors. This is intended to provide a methodological and conceptual framework for studying the problem of human consciousness and action in relation to health in a way that is consistent with both the values and purposes of student-centred learning and the claims of critical theory. It is suggested that such a critical curriculum of health is needed in order to ensure that the ‘knowledgeable doer’ Project 2000 aims to produce is indeed a qualitatively different kind of professional nurse practitioner. 相似文献

Osteoporosis, a common metabolic condition resulting in reduced bone mass, causes significant morbidity in affected individuals by predisposing them to osteoporotic fractures. To determine the relationship of scoliosis and osteoporosis, dual-energy X-ray absorptiometry (DXA) scans of 493 men and 762 women were analyzed according to their scoliotic status. No association was observed in the few scoliotic men without osteoarthritis of the spine compared to nonscoliotic men. Without osteoarthritis, scoliotic women had significantly decreased bone mass of the total hip and the femoral neck (p < 0.05) compared to nonscoliotic women, whereas in spine, bone mass was also decreased compared to nonscoliotic women, but not statistically significant. This suggests that scoliosis associates with bone loss, and affected women may benefit from early institution of therapeutic measures. 相似文献

The morale of nurses is a phenomenon often open to public comment without substantiated evidence. This study objectively explored the morale of nurses in a large district general hospital preparing for transition to National Health (NHS) Trust status. Information was sought using a 72-item questionnaire. The investigation was firmly centred around a structured theory which construes morale in terms of nine dimensions. The notion of morale being a construct synthesized of nine dimensions adds to the uniqueness of the study. Other studies fail to differentiate between the dynamic morale construct and the more complacent attitudes of job satisfaction. 相似文献

An initiative to develop a standard for professional development is outlined. The standard takes a structure, process, outcome format. Its development resulted in several initiatives being introduced to the unit including: the introduction of a self and peer review system, the introduction of learning contracts and the introduction of the concept of reflection. It was considered that these initiatives would promote individual professional accountability, increased self-awareness and reflective practice. The initiatives may be viewed in the context of PREP, United Kingdom Central Council for Nursing, Midwifery and Health Visiting (1990) and the Higher Award, English National Board for Nursing, Midwifery and Health Visiting (1991). The audit of the standard may be a tool to measure 'value for money' used in professional development. 相似文献

The aim of this preliminary empirical investigation was to explore the concept of self-determination and to discuss its applicability to psychiatric nursing. The data were collected with a questionnaire submitted to professional nurses ( n =127) working on long-term wards in four Finnish hospitals. Data analysis combined the methods of content analysis and quantitative statistics. A tentative concept apparatus was created in order to provide nursing science with a broader understanding of the issue at hand. Nurses identified various factors that act to restrict and to support self-determination: the most common restrictive factor was the patient's illness or condition, and the most common supportive factor was nursing intervention. Views differed on the importance of self-determination in the case of psychiatric patients; over half of the nurses described the right to self-determination as very important. On the basis of the findings it is concluded that self-determination is a valid concept for the psychiatric patient. It was also thought to serve the needs of education as well as evaluation. 相似文献

IMMUNOLOGICAL FEATURES OF HLA-B27 ANTERIOR UVEITIS 总被引:2,自引:0,他引:2

Analysis ol the immunological features of anterior Uveitis (AU) revealed a dichotomy of abnormalities defined in terms of the HLA-B27 status of the patient. HLA-B27-positive AU was characterised by the occurrence of ins autoantibodies and an absolute T cell lymphopenia during active disease which returned to normal with recovery. This phenomenon was not observed in HLA-B27-negative AU or in controls and could not be attributed to antilymphocyte antibodies as these were not detected. Furthermore, there were no changes in T-cell subsets (helper and suppressor T lymphocytes). Compared with HLA-B27-positive AU patients, the HLA-B27-negative group demonstrated elevated lgE levels and increased prevalence of smooth muscle autoantibodies. Key words: anterior Uveitis, HLA-B27, immunological abnormalities, T lymphocytes, autoantibodies. 相似文献

Summary 1. Twenty-two patients with infectious mononucleosis were studied by liver biopsy and paper electrophoresis of the serum proteins. The findings were compared with a similar group of 30 patients with infectious hepatitis.2. The essential histologic features of infectious mononucleosis were the presence in the hepatic sinusoids and portal tracts of chronic inflammatory cells resembling small lymphocytes, with essentially no parenchymal cell damage. Admixed with this lymphocytic infiltrate, but in relatively minimal numbers, were a few plasma cells and polymorphonuclear leukocytes. In addition, in infectious mononucleosis there were, with rare exceptions, no lipochrome-containing Kupffer cells. Thus, in the majority of cases, the histologic picture was distinct from that seen in infectious hepatitis. Only in comparing a few of the more severe infectious mononucleosis cases with subsiding infectious hepatitis cases was there any tendency for the two pictures to merge, and the distinction on histologic grounds between the two entities could be made in the great majority of cases.3. The most commonly seen abnormalities in the paper electrophoretic patterns of sera obtained from patients with infectious mononucleosis were decreased albumin, increased gamma globulin, not infrequent but variable changes in alpha2 globulin, and the presence of abnormal proteins migrating with mobilities intermediate to alpha2 and beta, and beta and gamma globulins. The abnormalities observed in infectious hepatitis were similar to those of infectious mononucleosis, except that in hepatitis alpha2 globulin was decreased more consistently, gamma globulin increased less frequently, and beta globulin, which was normal in practically all the cases of infectious mononucleosis, was increased in a considerable number of cases.4. Treatment of patients with infectious mononucleosis need not include prolonged bed rest and restriction of activity in an effort to avoid the development of chronic liver disease. 相似文献
