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.     

Fluoxetine in panic disorder

Twenty-five patients with a primary DSM-III-R diagnosis of panic disorder with or without agoraphobia were treated openly with the serotonin uptake inhibitor fluoxetine for up to 12 months. For most patients, treatment was initiated at 5 mg/day to minimize adverse effects previously reported with initiation at higher doses. Nineteen (76%) experienced moderate to marked improvement in panic attacks. Four (16%) were unable to tolerate fluoxetine due to adverse effects. Initiating treatment of panic disorder with low doses of fluoxetine may increase its acceptability and permit more patients to benefit from fluoxetine.     

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.     

Significance of diffuse cardiac activity on In-111 labeled leucocyte scans

To assess the significance of diffuse cardiac activity (DCA) seen on In-111 labeled leukocyte scans, we reviewed 87 studies performed over the last 4 years. Inflammatory cardiac conditions were seen as frequently in patients with DCA (15%) as those without (7%, P=0.3). There was a higher ratio of RBC:WBC in the final WBC preparation in the false-positive DCA group than the true positive DCA and no DCA groups. False-positive studies showing DCA are most likely due to residual blood pool activity.Presented in part, 70th annual meeting, Radiological Society of North America, Washington D.C., 25 November 1984
