Pathologic gambling.

Pathologic gambling and problem gambling affect approximately 5 to 15 million Americans and are common in young people. The community-minded family physician is in a good position to identify and assist patients who have gambling-related problems and thereby prevent or treat the resultant personal, family and social disruptions. Provider and community education about the depth and breadth of this condition is crucial for the identification and treatment of a growing problem. As with many psychologic conditions, identification of the disorder and treatment of the patient by the family physician comprise the primary treatment. Screening tools, treatment programs and self-help groups provide additional resources for the family physician. An illustrative case report demonstrates the importance of heightened awareness of and screening for this common condition.

Influence of a rural primary care clerkship on medical students' intentions to practice in a rural community.

The purpose of this study is to examine the relationship of a rural clerkship to medical students' interest in establishing careers in rural communities. The Association of American Medical Colleges Medical School Graduation Questionnaire (GQ) for years 1988 through 1997 was examined to compare the career plans of students graduating from Morehouse School of Medicine (MSM) with those of all students graduating from United States medical schools before the period 1988 through 1992 and after the period 1993 through 1997, after the inception of the rural clerkship at MSM. Select GQ data items examined include student demographics, medical school experiences, and career plans. Statistical analyses were used to compare pre- and post-clerkship responses for MSM students and to compare their responses with the national trends. Results indicate that, following a transition period, MSM students showed an increased preference for a future career in a rural community. A smaller upward trend in the national data was observed. There appears to be an association between the rural clerkship experience at MSM and the stated preferred career choices of the students.

Child sexual abuse prevention programs: a meta-analysis.

Conducted a meta-analytic evaluation of the effectiveness of school-based child abuse prevention programs. Literature searches identified 27 studies meeting inclusion criteria for use in this meta-analysis. The average effect size for all programs studied was 1.07, indicating that children who participated in prevention programs performed 1.07 SD higher than control group children on the outcome measures used in the studies. Analysis of moderator variables revealed significant effects for age, number of sessions, participant involvement, type of outcome measure, and use of behavioral skills training. Most important, programs presented over 4 or more sessions that allowed children to become physically involved produced the highest effect sizes. Although most often used only with younger children, findings suggest that active, long-term programs may be more effective for children of all ages.

Relation of the therapeutic alliance with outcome and other variables: a meta-analytic review.

To identify underlying patterns in the alliance literature, an empirical review of the many existing studies that relate alliance to outcome was conducted. After an exhaustive literature review, the data from 79 studies (58 published, 21 unpublished) were aggregated using meta-analytic procedures. The results of the meta-analysis indicate that the overall relation of therapeutic alliance with outcome is moderate, but consistent, regardless of many of the variables that have been posited to influence this relationship. For patient, therapist, and observer ratings, the various alliance scales have adequate reliability. Across most alliance scales, there seems to be no difference in the ability of raters to predict outcome. Moreover, the relation of alliance and outcome does not appear to be influenced by other moderator variables, such as the type of outcome measure used in the study, the type of outcome rater, the time of alliance assessment, the type of alliance rater, the type of treatment provided, or the publication status of the study.

Review of the evidence for an association between infant feeding and childhood cancer.

To assess the association between infant feeding and childhood cancer, a qualitative review of 9 published case-control studies was undertaken. The results of this synthesis suggest that children who are never breast-fed or are breast-fed short-term have a higher risk than those breast-fed for > or = 6 months of developing Hodgkin's disease (HD), but not non-Hodgkin's lymphoma or acute lymphoblastic leukemia. HD has features of a complex cellular immune disorder and of chronic infection. Human milk contains an extensive array of anti-microbial activity and appears to stimulate early development of the infant immune system. Artificially fed infants negotiate exposure to infectious agents without the benefits of this immunologic armament and do not do as well as breast-fed infants in resisting infection. Thus, human milk may make the breast-fed infant better able to negotiate future carcinogenic insults by modulating the interaction between infectious agents and the developing infant immune system or by directly affecting the long-term development of the infant immune system. Further research should attempt to confirm the association between infant feeding and HD in large, population-based, case-control studies. Improved measurement of infant feeding must be addressed if future studies are to advance our understanding of this association. In addition, studies of specific measures of immunity, particularly of cellular immune responses, should be conducted in populations of breast-fed and non-breast-fed young children.

Are all health plans created equal? The physician's view.

CONTEXT: The health care market is demanding increasing amounts of information regarding quality of care in health plans. Physicians are a potentially important but infrequently used source of such information. OBJECTIVE: To assess physicians' views on health plan practices that promote or impede delivery of high-quality care in health plans and to compare ratings between plans. SETTING: Minneapolis-St Paul, Minn. PARTICIPANTS: One hundred physicians in each of 3 health plans. Each physician rated 1 health plan. MAIN OUTCOME MEASURES: Likert-type items that assessed health plan practices that promote or impede delivery of high-quality care. RESULTS: A total of 249 physicians (84%) completed the survey. Fewer than 20% of all physicians gave plans the highest rating (excellent or strongly agree) for health plan practices that promote delivery of high-quality care (such as providing continuing medical education for physicians, identifying patients needing preventive care, and providing physicians feedback about practice patterns). Barriers to delivering high-quality care related to sufficiency of time to spend with patients, covered benefits and copayment structure, and utilization management practices. Ratings differed across health plans. For example, the percentage of physicians indicating that they would recommend the plan they rated to their own family was 64% for plan 1, 92% for plan 2, and 24% for plan 3 (P<.001 for all comparisons). CONCLUSIONS: Physician surveys can highlight strengths and weaknesses in health plans, and their ratings differ across plans. Physician ratings of health plan practices that promote or impede delivery of high-quality care may be useful to consumers and purchasers of health care as a tool to evaluate health plans and promote quality improvement.

A comprehensive weight-loss program for soldiers.

A weight-loss treatment program for active duty military personnel is discussed and evaluated. The Fat Loss and Exercise Program at U.S. Army Hospital, Bremerhaven, Germany, consisted of a 3-week inpatient treatment program and 6 months of weekly outpatient follow-up. The program combined a multidisciplinary team approach to the treatment of obesity--psychology, internal medicine, nursing, nutrition care, and physical therapy. Patients showed a significant weight and body fat loss [F(2,90) = 52.91 and 65.85, p < 0.001, respectively] from the initiation of treatment (mean = 205.9 pounds, 28.91%) to the end of the inpatient program (mean = 192.8 pounds, 25.97%) with maintenance over 6 months (mean = 190.4 pounds, 25.03%). Changes in cholesterol levels by treatment phase are also discussed. Results demonstrate positive increases in high-density lipoprotein at each phase. These results support a comprehensive, multidisciplinary inpatient treatment of obesity within the military.

Pregnancy experience after delivery of a child with a major birth defect: a population study.

OBJECTIVE: Data from a large population-based, case-control study were analyzed to determine whether women giving birth to children with major birth defects have different subsequent pregnancy patterns than those giving birth to live-born babies without defects. Other studies examining this phenomenon have been smaller, have not been population-based, or have not addressed the different effects that a wide range of major defects might have on mothers' subsequent pregnancy rates. METHODS: Mothers of 4918 infants with major birth defects born from 1968 through 1980 in metropolitan Atlanta were compared with mothers of 3029 control infants, frequency-matched on birth year, birth hospital, and race. RESULTS: The pregnancy rate in the first 3 years after the index birth was higher among case mothers (36%) than among control mothers (30%, P < .0001). This excess was seen for mothers of stillborn case infants (64%) and mothers of case infants who survived the first year of life (31%). Pregnancy rates varied by birth defect type. Maternal and infant factors varied among case and control subjects and influenced subsequent pregnancy rates. CONCLUSION: The reproductive behavior observed in this study supports the theory that mothers of nonsurviving children with birth defects compensate by acting to "replace" the lost child. Reproductive behavior was also strongly associated with having completed a previous pregnancy and by the type of birth defect.

Infant feeding and childhood cancer.

A case-control study was used to assess whether inadequate exposure to the immunological benefits of human milk may affect infants' response to infection and make them more susceptible to childhood malignancies. 201 Denver children with cancer diagnosed at 1.5-15 years of age were compared with 181 controls, who were selected to be similar to cases for age, sex, and area of residence. Infant feeding categories were: breast feeding (BF) greater than 6 months; BF less than or equal to 6 months; and artificial feeding (AF, or exclusive non-human milk feeding). Compared with BF greater than 6 months, a raised risk for total cancers was found in both BF less than or equal to 6 month and AF groups. This increased risk was largely due to an increased incidence of lymphoma (n = 26).

Management of sentence production demands.

This study examined the effects of variations in language complexity on young children's phonological accuracy and consistency of target words. A more general intent was to understand better the way in which developmental level and children's tolerance of speech variability influenced the management of processing demands. Seven children aged 22-34 months were seen six times over a 4-month period. During these sessions, children were presented with an elicited imitation task consisting of 18 stimulus words, each of which occurred in eight sentences of varying language complexity. Younger children in Language Stage III were found to be more influenced by changes in language complexity than older children in Language Stages IV and V. Within-stage differences were also found. Moreover, in contrast to previous research, children showed as many improvements in phonological accuracy with increases in language complexity as they did decreases in phonological accuracy. It was suggested that between-stage differences were primarily caused by differences in developing speech, language, and cognitive abilities, whereas within-stage differences were primarily caused by differences in the extent to which children tolerated variability in their speech. Based on this contention, some speculations were offered concerning the way in which normal and disordered children manage processing demands.
