The Dartmouth Health Promotion Study: A Failed Quest for Synergy in School Health Promotion

ABSTRACT: The Dartmouth Health Promotion Study was a longitudinal, quasi-experimental field study with a qualitative research arm, designed to learn whether coordinating school health instruction, health services, and a healthful environment enhanced the program's effect on the heart health and mental health of children. The research strategy — the Coordinated Approach — was applied to approximately 300 children in each of two cohorts in grades four to six attending nine trial schools; a further 600 children attended 10 comparison schools in Dartmouth and nine distal comparison schools. Although the qualitative analysis demonstrated that positive feelings were engendered in most areas of the study, when either the classroom or the individual was used as the unit of analysis, the Coordinated Approach did not have a more favorable effect on the heart or mental health of children than did the standard school health program. Thus, the effect of an existing school health program was not directly enhanced through coordinating its components.     

Concentric sclerosis (Baló): Morphometric and in situ hybridization study of lesions in six patients

Brain tissues from 6 patients with concentric sclerosis (Baló) were examined by in situ hybridization, immunocytochemistry, morphometry, and histological methods. The patients were 24 to 48 years old and had progressive cerebral symptoms and signs that lasted 15 to 100 days. Large demyelinative lesions, most frequent in the frontal white matter, contained alternating bands of demyelinated and partly myelinated white matter that were arranged in concentric or mosaic patterns. In the areas of demyelination, axons were relatively well preserved and there were perivascular inflammatory infiltrates. In 2 specimens, lesions contained regions with the characteristic appearance of actively demyelinating multiple sclerosis plaques. Oligodendroglial densities were highest in normal-appearing white matter, lower in partially myelinated areas, and lowest in demyelinated areas, which also contained many hypertrophic astrocytes closely associated with oligodendroglia. Messenger RNA levels for myelin-related proteins followed the same pattern; they were lowest in demyelinated areas, higher in partially myelinated areas, and highest in normal-appearing white matter beyond lesion margins. Our findings suggest that concentric sclerosis is a variant of multiple sclerosis, that oligodendroglial loss is important in the pathogenesis of demyelination, and that partially myelinated areas probably represent stages of ongoing myelin breakdown rather than remyelination of previously demyelinated areas.     

Ejection fraction by combined inverse Fourier analysis and second-derivative technique: Correlation with isocontour method

Summary In order to measure ejection fractions (EFs) from nuclear ventriculograms, we devised a semi-automated edge-detection technique based on a combination of inverse Fourier analysis and second-derivative techniques. Initial clinical studies showed that, for the left ventricle, our method gives EF values statistically identical with those obtained using a conventional isocontour technique. For the right ventricle, however, the values obtained using the two methods were somewhat more at variance. Despite requiring a longer processing time, the results obtained with our method are reproducible because less operator intervention is necessary.     

The Educational Commission for Foreign Medical Graduates: global efforts in graduate medical education

In addition to its certification programme, which assesses the readiness of foreign medical graduates to enter graduate medical education programmes in the USA, the Educational Commission for Foreign Medical Graduates (ECFMG) is involved in a number of other programmes in international medical education. These include: (1) continuing to provide sponsorship for exchange visitors in graduate medical education programmes in the USA; (2) the development of a clinical skills assessment that is currently being introduced in pilot projects in the USA and abroad and will eventually become a component of the ecfmg certification process; (3) funding and administration of two fellowship programmes that provide foreign scholars (clinicians and basic scientists) with the opportunity to spend up to one year in a US medical school; (4) collaboration with the World Health Organization on the upcoming revised edition of the World Directory of Medical Schools ; and (5) co-sponsorship, with the World Health Organization, of a consultation on quality medical education oriented towards attaining a global consensus on the definition and the elements of quality in medical education and on the most appropriate ways to evaluate quality.     

Relationship with God and the Quality of Life of Prostate Cancer Survivors

This study explored the role of relationship with God with respect to the quality of life of men with prostate cancer. Thirty-four men with prostate cancer completed questionnaires on demographic and illness factors, aspects of relationship with God (e.g., God image), nonreligious resources (e.g., optimism) and physical, social and emotion functioning. Results showed that relationship with God was a significant factor in the prediction of role, emotional and social functioning for these men after controlling for age, reported severity of treatment reactions and nonreligious resources. Notably, different aspects of relationship with God (e.g., causal attribution) evidenced different associations with functioning and the nonreligious resource of perceived health control. Such results suggest that relationship with God may function in a complex manner as a resource in coping with prostate cancer. Longitudinal research is needed to clarify the role of religious/spiritual resources in the short- and long-term quality of life of men with prostate cancer.
