Primary care providers' views of precepting nurse practitioner students

PURPOSE: To explore perceived barriers to and facilitators of precepting as viewed by experienced community-based preceptors. DATA SOURCES: Twenty-four nurse practitioner and physician preceptors participated in a 20-minute telephone interview, using a semi-structured format. The interviews were audio-taped and transcribed. Constant comparative analysis was used to organize the preceptors' responses into thematic categories. CONCLUSIONS: Overall, most preceptors were satisfied with the precepting experience; however, many preceptors cited increasing difficulty with teaching students in primary care sites due various organizational constraints such as the imperative to increase productivity. Good communication with school of nursing faculty was cited as the key factor to continued willingness to precept. IMPLICATIONS FOR PRACTICE: Understanding factors that are important for preceptors continuing in their clinical teaching role is important for schools of nursing, especially given the increasing time-limitations that many providers face due to social and economic changes in health-care delivery.     

Preparedness for hospital practice among graduates of a problem-based,graduate-entry medical program

OBJECTIVE: To compare preparedness for hospital practice between graduates from a problem-based, graduate-entry medical program and those from other programs (undergraduate problem-based and traditional). DESIGN: Survey of graduates (by mailed questionnaire) and organisers of clinical training (by semistructured interview); results were compared with published results of surveys of graduates from other programs. SETTING AND PARTICIPANTS: All graduates of the first intake of the University of Sydney graduate-entry medical program were surveyed at the end of their first intern year (2001), along with the director of clinical training or intern manager at each of the New South Wales hospitals that employed the graduates. MAIN OUTCOME MEASURES: Graduates' self-reported level of preparedness in the eight domains of the Preparation for Hospital Practice Questionnaire; and organisers' opinions of their strengths and weaknesses. RESULTS: 76 of 108 graduates from the graduate-entry program (70%) and organisers of clinical training at all 17 hospitals participated. Graduates from the program felt more prepared than did those from other programs in five of the eight domains assessed (interpersonal skills, confidence, collaboration, holistic care, and self-directed learning) and no less prepared in any domain. Organisers rated the graduates highly, especially in clinical competence, confidence, communication and professional skills. Opinions of interns' knowledge of basic sciences conflicted, with strengths and weaknesses mentioned with equal frequency. CONCLUSION: Graduates from the graduate-entry, problem-based program are at least as well prepared for their intern year as graduates from traditional and undergraduate problem-based programs.

Dietary antioxidant intake in patients at risk for second primary cancer

OBJECTIVES: To analyze dietary antioxidant intake for head and neck cancer patients at risk for development of second primary cancers. STUDY DESIGN: Prospective observational study. METHODS: Twenty-four patients underwent three random, unscheduled, 24-hour dietary recalls over a 15-day period within 6 to 60 months after successful treatment for stage I or II oral cavity squamous cell carcinoma. RESULTS: The study sample had a lower mean daily dietary intake of fruits and vegetables and antioxidant nutrients, including vitamins A, C, E, and total carotenes than age- and sex-matched historic control subjects (all P <.05 except vitamin A). A positive linear correlation was noted between daily servings of F&V and dietary intake of vitamins A, C, E, and total carotenoids (all P <.05 except vitamin A). Compared to current recommendations, the study sample had lower mean daily dietary intake of vitamins A, C, and E (P =.81,.06, and <.01) and servings of fruits and vegetables (P <.01). When vitamin supplements were included in the analysis, mean daily intake exceeded recommended dietary allowance (RDA) for vitamins A, C, and E (all P <.05). CONCLUSION: This study suggests that patients treated for early-stage oral cavity carcinoma, at risk for second primary cancers, have a statistically significant deficiency in dietary (food) sources of antioxidant nutrients when compared with both historic control subjects and current recommendations. Vitamin supplementation significantly exceeded current RDAs. Because increased fruit and vegetable intake, but not vitamin supplementation exceeding RDA, is associated with reduced cancer risk, physicians may consider recommending at least five daily servings of fruits and vegetables as an alternative to vitamin supplementation.     

Quantitative analysis of rat inner ear blood flow using the iodo[(14)C]antipyrine technique

A number of different qualitative and quantitative techniques have been used to measure inner ear blood flow and all have required that the animal be anesthetized. It is well known that anesthesia can cause a variety of circulatory as well as other systemic changes. In this study, we have employed a technique commonly used for quantifying brain blood flow, the iodo[(14)C]antipyrine technique ([(14)C]IAP). Unlike other techniques, [(14)C]IAP can be used in unanesthetized animals under conditions that are nearly normal, it is non-invasive, it can be used reliably in regions of low local blood flow, and data can be acquired from both the periphery and central nervous system. Results show that blood flow to the lateral wall of the basal turn of the cochlea (387 +/- 19 microl/g/min) is significantly higher (P<0.001) than that of the utricular macula (189 +/- 23 microl/g/min), horizontal (186 +/- 22 microl/g/min), superior (185 +/- 22 microl/g/min), or posterior canal crista (185 +/- 25 microl/g/min). Surprisingly, blood flow to all of the vestibular end-organs is remarkably similar. The use of this technique should allow pharmacological experimentation on inner ear blood flow without the unknown complications of anesthesia or invasive procedures.
