Evaluating clinical educators: an employer's perspective

An Australian school of nursing's attempt to introduce an evaluation process required by management for clinical educators involved in undergraduate preregistration education is discussed Reliance on student feedback and clinical agencies' perceptions of the quality of teaching were seen as inadequate mechanisms for evaluation The evaluation process adopted incorporated observation of the educators together with self-reflection on their performance We conclude that post-briefings were poorly used and generally not reflective Educators relied heavily on their clinical skills and used a limited range of teaching strategies Whilst evaluation of clinical educators was time consuming and therefore costly, it is argued that it is essential to the integrity of the course The evaluation process has provided direction for support and development of clinical educators within the context of the curriculum     

What's in a burger?

In an attempt to confirm the presence or absence of central nervous tissue in commercially prepared beefburgers, four burgers were processed and stained using routine histological laboratory techniques. Constituent parts of the burgers could be identified readily. In this small sample no central nervous tissue was found. There is currently considerable general interest in the contents of foodstuffs, particularly now that certain specified bovine offals as well as central nervous tissue have been banned from human consumption. Conventional histological techniques may be of value in analysing the ingredients of beef products.     

An Atypical Recurrence of Endometrial Carcinoma Following Estrogen Replacement Therapy

Following an abdominal hysterectomy and bilateral salpingoophorectomy wherein a superficial (1.6 mm) well-differentiated endometrial cancer and bilateral ovarian serous cystadenomas were discovered, estrogen replacement was given. One year later the patient presented with a 9 × 7-cm left groin recurrence. Patients with endometrial carcinoma may request estrogen replacement. The benefits of such replacement are well recognized; however, these patients also need to be counselled that hormonal replacement may be complicated by recurrence. Physicians need to be cognizant of symptoms or signs which would suggest disease recurrence at unusual sites in these patients who are perceived as being at low risk for recurrent disease.     

The implications of Project 2000 and the formation of links with higher education for the professional and academic needs of nurse teachers in the United Kingdom

A national study was conducted between 1991 and 1994 to explore and describe the changing role of the nurse teacher following the introduction of Project 2000 pre-registration nursing courses. Multiple methods were used to collect data from a wide variety of respondents (nurse teachers, midwife teachers, clinical nurses, health service managers and higher education lecturers). This paper presents the findings relating to the impact of Project 2000 and the move into higher education on the continuing educational needs of nurse teachers. Views on college strategies for staff development, the changing nature of teachers'academic and professional development needs and the problems of the conflicting demands experienced are reported. The research highlights the need for clinical credibility to be clearly defined in relation to nurse teachers and for educational institutions to place more emphasis on teachers'clinical development if the rhetoric of policy is to become a reality.     

Leukotriene receptor antagonists. 2. The [[(tetrazol-5-ylaryl)oxy]methyl]acetophenone derivatives

A series of [[(tetrazol-5-ylaryl)oxy]methyl]acetophenones was synthesized and evaluated as antagonists of leukotriene D4 induced contractions of guinea pig ileum. Substitutions at the 3-position of the acetophenone with ethyl (66), propyl (68), butyl (83), and isobutyl (84) gave -log IC50 values of 7.9, 8.0, 7.8, and 7.7, respectively. Equally potent compounds were obtained when the tetrazol-5-yl group was connected to the second benzene ring in the para position with a chemical bond (67), methylene (68), or ethylene (71). For retention of high antagonist activity, the acetophenone should be substituted in the 2-position by a hydroxyl group and the tetrazole ring should have an acidic hydrogen atom. 1-[2-Hydroxy-3-propyl-4-[[4-(1H-tetrazol-5-ylmethy) phenoxy]methyl]phenyl]ethanone (68, LY1632443) has undergone extensive pharmacologic evaluation for its potential as an antiasthma agent.     

Diabetes alters μ and κ opioid binding in rat brain regions: comparison with effects of food restriction

Diabetic rats display changes in opioid pharmacology and brain regional levels of opioid peptides and prodynorphin mRNA. Previous investigations of opioid receptor binding, carried out in whole-brain homogenates, have, however, failed to detect changes. In the present study, quantitative autoradiography was used to measure μ and κ opioid receptor binding in discrete brain regions of streptozotocin-treated diabetic rats. Measurement was limited to regions that previously displayed opioid binding changes in chronically food-restricted rats, since our primary aim is to identify brain mechanisms that mediate adaptive responses to persistent metabolic need and adipose depletion. Diabetics displayed strong trends or statistically significant changes which matched seven of the thirteen binding changes observed in food-restricted rats. In no case did diabetics display changes in the opposite direction. The two statistically significant changes common to food-restricted and diabetic rats are increased κ binding in the medial preoptic area and decreased μ binding in the lateral habenula. The possible functional significance of these changes is discussed.
