Reproducibility and validity of an extensive semiquantitative food frequency questionnaire among Greek school teachers

The involvement of mental health professionals in determinations of dangerousness is both common and controversial. Among the various contexts for these evaluations, the release of potentially violent forensic patients from maximum security facilities evokes justified concern from involved experts and apprehension to outrage from the immediate community. We sought to examine how conclusions are reached on dangerousness at two sequential stages: clinical recommendations and Manifest Dangerousness Hearings decisions. In an archival study of 245 patients, we found that lack of progress in the institution and physical assaultiveness were the strongest correlates with dangerousness. In contrast, experts and review boards appeared to be relatively less influenced by diagnosis, types of treatment, and sociodemographic variables.     

Study of prediagnostic selenium level in toenails and the risk of advanced prostate cancer

BACKGROUND: In a recent randomized intervention trial, the risk of prostate cancer for men receiving a daily supplement of 200 microg selenium was one third of that for men receiving placebo. By use of a nested case-control design within a prospective study, i.e., the Health Professionals Follow-Up Study, we investigated the association between risk of prostate cancer and prediagnostic level of selenium in toenails, a measure of long-term selenium intake. METHODS: In 1986, 51,529 male health professionals aged 40-75 years responded to a mailed questionnaire to form the prospective study. In 1987, 33,737 cohort members provided toenail clippings. In 1988, 1990, 1992, and 1994, follow-up questionnaires were mailed. From 1989 through 1994, 181 new cases of advanced prostate cancer were reported. Case and control subjects were matched by age, smoking status, and month of toenail return. Selenium levels were determined by neutron activation. All P values are two-sided. RESULTS: The selenium level in toenails varied substantially among men, with quintile medians ranging from 0.66 to 1.14 microg/g for control subjects. When matched case-control data were analyzed, higher selenium levels were associated with a reduced risk of advanced prostate cancer (odds ratio [OR] for comparison of highest to lowest quintile = 0.49; 95% confidence interval [CI] = 0.25-0.96; P for trend = .11). After additionally controlling for family history of prostate cancer, body mass index, calcium intake, lycopene intake, saturated fat intake, vasectomy, and geographical region, the OR was 0.35 (95% CI = 0.16-0.78; P for trend = .03). CONCLUSIONS: Our results support earlier findings that higher selenium intakes may reduce the risk of prostate cancer. Further prospective studies and randomized trials of this relationship should be conducted.     

Frequent nut consumption and risk of coronary heart disease in women: prospective cohort study

OBJECTIVE: To examine the relation between nut consumption and risk of coronary heart disease in a cohort of women from the Nurses' Health Study. DESIGN: Prospective cohort study. SETTING: Nurses' Health Study. SUBJECTS: 86 016 women from 34 to 59 years of age without previously diagnosed coronary heart disease, stroke, or cancer at baseline in 1980. MAIN OUTCOME MEASURES: Major coronary heart disease including non-fatal myocardial infarction and fatal coronary heart disease. RESULTS: 1255 major coronary disease events (861 cases of non-fatal myocardial infarction and 394 cases of fatal coronary heart disease) occurred during 14 years of follow up. After adjusting for age, smoking, and other known risk factors for coronary heart disease, women who ate more than five units of nuts (one unit equivalent to 1 oz of nuts) a week (frequent consumption) had a significantly lower risk of total coronary heart disease (relative risk 0.65, 95% confidence interval 0.47 to 0.89, P for trend=0.0009) than women who never ate nuts or who ate less than one unit a month (rare consumption). The magnitude of risk reduction was similar for both fatal coronary heart disease (0.61, 0.35 to 1.05, P for trend=0.007) and non-fatal myocardial infarction (0.68, 0.47 to 1.00, P for trend=0.04). Further adjustment for intakes of dietary fats, fibre, vegetables, and fruits did not alter these results. The inverse association persisted in subgroups stratified by levels of smoking,use of alcohol, use of multivitamin and vitamin E supplements, body mass index, exercise, and intake of vegetables or fruits. CONCLUSIONS: Frequent nut consumption was associated with a reduced risk of both fatal coronary heart disease and non-fatal myocardial infarction. These data, and those from other epidemiological and clinical studies, support a role for nuts in reducing the risk of coronary heart disease.     

Patterns of hospitalization in elderly patients with asthma and chronic obstructive pulmonary disease

The purpose of this study was to describe the impact of asthma and chronic obstructive pulmonary disease (COPD) in the elderly on health care utilization. The Health Care Financing Administration (HCFA) file for the year 1984 through 1991 involving beneficiaries < or = 65 yr were searched for the diagnoses of asthma and COPD by ICD-9 codes. The study groups were created by determining the first admission for an exacerbation of either disease during each year from 1984 through 1991. Patients were identified by their social security number. The 1984 cohort consisted of 56,692 patients with asthma exacerbation and 162,899 with COPD exacerbation. The 1991 cohort consisted of 67,758 patients with asthma exacerbation and 131,974 patients with COPD exacerbation. In addition, the 1984 cohort was tracked by social security number for evidence of rehospitalization for either asthma or COPD through 1991. Length of hospitalization increased as patients grew older. The discharge rate to an independent living facility diminished as age increased. The use of convalescent and nursing homes or home health care after discharge more than doubled from 1984 through 1991. The utilization of health care resources by elderly patients with asthma and COPD is immense, both during hospitalization and after discharge.     

A prospective study of dietary fiber types and symptomatic diverticular disease in men

To examine prospectively dietary fiber calculated from food composition values based on analytic techniques and specific dietary fiber types in relation to risk of diverticular disease, we analyzed data from a prospective cohort of 43,881 U.S. male health professionals 40-75 y of age at base line; subjects were free of diagnosed diverticular disease, colon or rectal polyps, ulcerative colitis and cancer. The insoluble component of fiber was inversely associated with risk of diverticular disease relative risk (RR) = 0. 63, 95% confidence interval (CI), 0.44-0.91, P for trend = 0.02, and this association was particularly strong for cellulose (RR = 0.52, 95% CI, 0.36-0.75, P for trend = 0.002). The association between diverticular disease and total dietary fiber intake calculated from the AOACstandards method was not appreciably different from results using the Southgate or Englyst method [for AOAC method, RR = 0.60, 95% CI, 0.41-0.87; for Southgate method, RR = 0.61, 95% CI, 0.42-0. 88; for Englyst method, RR = 0.60, 95% CI, 0.42-0.87, for the highest quintiles]. Our findings provide evidence for the hypothesis that a diet high in dietary fiber decreases the risk of diverticular disease, and this result was not sensitive to the use of different analytic techniques to define dietary fiber. Our findings suggest that the insoluble component of fiber was significantly associated with a decreased risk of diverticular disease, and this inverse association was particularly strong for cellulose.     

Type of situation and sex of counselor in assertive training.

30 female undergraduates were given training in making complaints, small talk, and saying no to unreasonable requests. Significant improvement occurred in all 3 areas; however, there was significantly more improvement for making complaints than for saying no to unreasonable requests. Ss seen by a male counselor changed significantly more than Ss seen by a female counselor. (15 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Review of moderate alcohol consumption and reduced risk of coronary heart disease: is the effect due to beer, wine, or spirits

OBJECTIVES: To review the effect of specific types of alcoholic drink on coronary risk. DESIGN: Systematic review of ecological, case-control, and cohort studies in which specific associations were available for consumption of beer, wine, and spirits and risk of coronary heart disease. SUBJECTS: 12 ecological, three case-control, and 10 separate prospective cohort studies. MAIN OUTCOME MEASURES: Alcohol consumption and relative risk of morbidity and mortality from coronary heart disease. RESULTS: Most ecological studies suggested that wine was more effective in reducing risk of mortality from heart disease than beer or spirits. Taken together, the three case-control studies did not suggest that one type of drink was more cardioprotective than the others. Of the 10 prospective cohort studies, four found a significant inverse association between risk of heart disease and moderate wine drinking, four found an association for beer, and four for spirits. CONCLUSIONS: Results from observational studies, where alcohol consumption can be linked directly to an individual's risk of coronary heart disease, provide strong evidence that all alcoholic drinks are linked with lower risk. Thus, a substantial portion of the benefit is from alcohol rather than other components of each type of drink.     

An ecological study of the effectiveness of mammography in reducing breast cancer mortality

OBJECTIVES: The purpose of this study was to determine the relation of screening mammography to breast cancer incidence and case fatality. METHODS: In a sample of White female Medicare beneficiaries hospitalized in 1990-1991, age-adjusted breast cancer incidence and 2-year case fatality rates were estimated and compared with the frequency of mammographic screening from a population-based survey. RESULTS: The average rates for incidence, case fatality, and mammography within 5 years in 29 states were 414/100,000, 18.8%, and 59.2%, respectively. There was a positive state-level correlation between mammography rates and incidence and an inverse correlation between mammography and case fatality. CONCLUSIONS: High screening mammography rates in some states are associated with reduced breast cancer case fatality rates, presumably as a result of diagnosis of earlier stage cancers.     

Weight gain through self-control procedures.

21 underweight (at least 10%) undergraduates were assigned to either a self-reinforcement condition, a self-punishment condition, or to a discussion-reflection control condition. Ss received 1 weekly treatment session over a 5-wk period. Following treatment, the self-reinforcement groups gained significantly more pounds (kilograms) than either the self-punishment or the control group. This effect was maintained at a 12-wk follow-up. The punishment and control groups did not differ significantly at posttest or at follow-up. Similar results were obtained when percentage of weight change was analyzed, with the treatment effect significant at follow-up.

"Self Verbalization and Emotional Arousal": Erratum.

Reports an error in the original article by David C. Rimm and Stuart B. Litvak (Journal of Abnormal Psychology, 1969[April],74[2],181-187). On page 187 of the article corrections need to be made in the first and second paragraphs. (The following abstract of this article originally appeared in record 1969-09037-001.) Investigated certain assumptions derived from A. Ellis' theory relating implicit verbalization to emotional arousal. Emotional responses (GSR and respiration changes) of 18 undergraduates instructed to silently read sequences of affectively loaded sentences were compared with those of 9 Ss who read neutral sentences. The relationship between relevance to S of the content of the sentences and level of emotional response was investigated, as was the effect of sentence type (observation, inference, or evaluative conclusion) on level of emotional response. Results were that Ss showed a significantly greater response to affectively loaded than to neutral sentences on 2 out of 3 responses measures. Neither relevance nor sentence type were found to have any significant effect. Results were interpreted as offering only partial support for the theory.
