'What do you notice?' Using posters containing questions and general instructions to guide preschoolers' science and mathematics learning

To increase preschoolers' science and mathematics learning experiences both within and outside the classroom, we developed age-appropriate materials containing general questions and instructions that teachers and parents could use when interacting with their students and children. The questions and instructions were related to a specific science or mathematics skill (e.g., classifying), but were general enough so that they could be applied to a variety of situations. Observations of three classrooms and interviews with the classroom teachers and aides, and the parents of the children in the classrooms suggested that use of these materials was beneficial to the children, teachers, and parents, and resulted in increasing the amount of science and mathematics activities and discussions in two of the classrooms as well as outside the classrooms.     

Learning and retention of movement sequences in Parkinson's disease.

The purpose of this study was to examine motor learning and retention given extensive practice in two fundamentally different movement sequences. One sequence was a memory-driven task (performing a series of whole body positions from memory) and the other a context-driven task (buttoning). Practice took place over 3 weeks, with performance measured weekly; retention was measured weekly for 3 weeks after practice. There were 7 people with Parkinson's disease (PD) and 7 age-matched neurologically healthy people who participated in this study. Both groups improved performance on both tasks with practice, with the majority of the change for the PD group occurring between 1 and 2 weeks of practice. Although those with PD did not necessarily perform as well as age-matched controls, they learned both sequences in a manner similar to age-matched controls, and exhibited retention across the 3-week retention interval. If people with PD are given sufficient practice they can learn and retain both memory-based and context-driven movement sequences as well as age-matched controls. The results provide support for maintaining physical activity and for intervention through movement therapy.     

Routinely collected general practice data aids identification of people with hyperglycaemia and metabolic syndrome.

AIMS: To assess the performance of a risk score comprising data routinely available in general practice records (age, gender, body mass index, family history of diabetes, smoking habits and prescribed anti-hypertensive drugs or steroids) in detecting diabetes, impaired glucose tolerance and metabolic syndrome. METHODS: In a population-based, cross-sectional study in a semi-rural general practice in Jutland, Denmark, Cambridge Risk Scores were calculated for 1355 patients without known diabetes (69% response rate) who completed questionnaires and underwent anthropometric measurement and an oral glucose tolerance test. RESULTS: Prevalences of diabetes, impaired glucose tolerance and metabolic syndrome were 2.29% (95% CI: 1.56-3.23), 6.64% (95% CI: 5.38-8.10) and 13.4% (95% CI: 11.5-15.2), respectively. Area under the ROC curve for the risk score and diabetes was 83.8% (75.9-91.7) and for metabolic syndrome [European Group for the Study of Insulin Resistance (EGIR)] was 78.1% (74.6-81.6). Twenty per cent of the population had a risk score above 0.246; at this threshold the sensitivity to detect diabetes was 71.0% (53.4-83.9), the specificity 81.2% (79.0-83.2), positive predictive value 8.1% (6.6-10.0) and likelihood ratio 3.77 (2.94-4.85). For metabolic syndrome (EGIR) corresponding values for sensitivity were 50.3% (43.1-57.5), specificity 84.7% (82.5-85.6), positive predictive value 33.6% (28.2-39.4), and likelihood ratio 3.28 (2.69-4.00). CONCLUSIONS: Undiagnosed hyperglycaemia and metabolic syndrome are common. The Cambridge Risk Score is a practical first step in a screening procedure to identify individuals with these disorders who might benefit from diagnostic testing or to direct preventive interventions.     

Physician assistants in academic radiology: the harborview experience

We describe a model of how physician assistants can be used in an academic medical center to expand radiologist productivity, and to enhance the departmental academic and educational missions. At Harborview Medical Center, following a training program and graduated responsibility under supervision, physician assistants provide initial interpretation of radiology studies, consultation to referring physicians, and perform less complicated interventional procedures. Acceptance of physician assistants by the radiologists, radiology residents, and referring physicians has been high. Although the impact of physician assistants on departmental clinical productivity is difficult to measure, our data suggest that radiologists are more efficient when physician assistants are assigned to service, both in terms of numbers of studies interpreted, and timeliness of reporting and billing. As a result of the success of our program, we believe that physician assistants can have an important role in radiology practice.     

Practice standards for optometry and optometric practice accreditation

Background: To assist optometrists to deliver care more efficiently and effectively, in 1995 Optometrists Association Australia decided to develop standards that would assist optometrists in better managing their practices. Existing practice management standards for health professionals were thought to be either not specific enough for optometric practice or to have shortcomings in the context of optometric practice in Australia. Methods: Following a literature search, material previously developed by Optometrists Association Australia to assist practitioners with management of their practices and standards from other professions were used to assist with the development of a draft set of standards for optometric practices in Australia. Successive drafts were circulated for comment to optometrists in practice, non‐optometrists with experience in the development of practice standards for other health professions and to Australian General Practice Accreditation Limited. The comments were used to refine the standards and the accreditation guidelines to their final form. Results: Optometric Practice Standards suitable for use in a practice accreditation program were developed. The standards comprise seven sections—Practice administration, Quality assurance, Rights and needs of the patient, Practice services, Practice facilities, Communication and Patient records. These sections are divided into criteria that provide the detail of the requirements of the standard. Indicators describing how criteria can be assessed accompany the criteria.     

How do family practitioners perceive surgery for the morbidly obese?

BACKGROUND: Little is known about the level of knowledge and comfort with bariatric surgery among family practice physicians. METHODS: Surveys were sent to all family practitioners in Connecticut querying the practice type and knowledge of bariatric surgery. The results were analyzed for the prevalence of opinion. RESULTS: Of 620 surveys sent out, 129 (21%) were completed. Of the 129 respondents, 73% were men, aged 31-79 years, and 92% were board certified, with an average of 19 years' experience. The average body mass index of respondents was 26 kg/m2 (range 16-40). Only 4% of respondents had a body mass index >30 kg/m2. Physicians reported a patient obesity rate of 43%. Of the 129 respondents, 88% believed obesity was difficult to control with diet and exercise alone. Only 6% thought obesity was best controlled surgically. Also, 85% of respondents had referred a patient for gastric bypass, although only 57% were comfortable explaining the procedure. The most common reason for refusal to refer was fear of complications and death. Additionally, 55% correctly listed a body mass index of 40 kg/m2 as qualifying for bariatric surgery without comorbidities; 48% identified the mortality rate of surgery as <1%, with 4% of respondents reporting >10%; and 84% were familiar with gastric bypass, 66% with LapBand, 33% with vertical banded gastroplasty, and 5% with duodenal switch. The respondents believed that nausea was the most common side effect, followed by anemia and fatigue. Finally, 53% believed bowel obstruction was common. CONCLUSIONS: The results of our study have shown that misconceptions about bariatric surgery exist in the family practice community despite the increasing frequency of these procedures. Educational programs need to be designed to assist family practitioners in treating and referring obese patients.     

Choosing a career in general practice: the influence of medical schools

Summary. This paper reviews the literature on career choice to investigate the undergraduate influences on the preference of Australian graduates for a career in general practice. Although isolation of influencing factors is difficult, admission criteria and undergraduate curricula may influence career preference. As the institutional environment of medical schools is weighted towards scientific research and specialized medicine, medical students may be socialized into choosing non-generalist careers. Medical schools should consider broadening selection criteria and curriculum exposure to produce graduates with a broad range of career interests.     

An adjusted version of Kohlberg's moral theory: discussion of its validity for research in nursing ethics

Critics of Kohlberg's moral theory today focus on the content of his theory and more specifically on its justice-orientated moral concept. This has led to the well-known 'justice-care debate'. The purpose of this article is to critically examine the validity of Kohlberg's moral theory for research in nursing ethics from a caring perspective (referring to the content) as well as from a cognitive-structural perspective (referring to the basic assumptions of the model). The analysis points to the usefulness and value of the cognitive-structural model to empirically study nurses' ethical behaviour; the content of Kohlberg's model, however, needs to be adapted by adding a caring perspective as well as some personal and situational variables. An adjusted version of Kohlberg's model is proposed and discussed.
