A conceptual framework for the roles of legislation and education in reducing exposure to environmental tobacco smoke.

More and more legislation regulating smoking in public places is being enacted. A conceptual model is proposed incorporating a large number of factors that may affect smokers' compliance with resulting restrictions. The model stems from findings in our own research and from a consideration of the literature.

The effects of counseling on smoking cessation among patients hospitalized with chronic obstructive pulmonary disease: a randomized clinical trial.

Seventy-four cigarette-smoking patients admitted with COPD to the Chest Unit of a 600-bed teaching hospital served as subjects for a randomized trial of smoking cessation counseling. All patients were advised to quit smoking and smoking in the unit was not allowed. One-half of the patients were, in addition, provided with a self-help manual and three to eight 15- to 20-min counseling sessions on alternate days while in hospital.

Self-reported long-term smoking cessation in patients with respiratory disease: prediction of success and perception of health effects.

Smoking status of 372 patients with respiratory disease, who had been advised to quit smoking by a respiratory specialist, was assessed six months after the advice. A multiple logistic regression model was developed for prediction of successful abstinence. The patients were again followed four to seven years later.

The role of health beliefs in compliance with physician advice to quit smoking.

The Health Belief Model has been proposed to account for patient compliance with therapeutic regimens. The purpose of the present study was to evaluate the utility of this theoretical formulation in accounting for compliance with physician advice to quit smoking among patients with pulmonary disease. Three hypotheses were examined: (1) probability of cessation of smoking is positively related to strength of Health Beliefs; (2) Health Beliefs can be used to explain relationships observed between other variables and compliance; (3) reason for smoking accounts for discrepancies between Health Beliefs and compliance.

Sexual and socioeconomic factors affecting the risk of past infections with herpes simplex virus type 2.

Between November 1978 and May 1980, a cross-sectional survey of 566 females and 391 males, aged 35 to 50 years, living in metropolitan Toronto, was conducted to examine the influence of socioeconomic status and sexual behavior on the occurrence of antibodies to herpes simplex virus type 2. Antibodies to the virus were detected in 17.5% of females and 12.

Direct and indirect measures of patient satisfaction with physicians' services.

This research examines alternative measures of patient satisfaction. Three measures were compared: (1) a direct measure to evaluate how the patient felt about his own personal physician, (2) an indirect measure that assessed attitudes about physicians in general, and (3) a measure designed to be intermediate between these two. Responses to the three measures were found to differ: the levels of satisfaction increased with the directness of the measure used; indirect evidence that this relationship could not be attributed solely to a patient's reluctance to criticize his own physician is also provided.

Survival of nieces and nephews of schizophrenic patients.

Evidence was found against the hypothesis that heterozygous carriers of a schizophrenic gene have a reproductive advantage through enhanced fertility. In consequence an investigation was made of the possibility that an advantage is gained through diminished early mortality among the off-spring of carriers. The results were equivocal.

Fertility of the sibs of schizophrenic patients.

This investigation has provided evidence against the hypothesis that heterozygous carriers of schizophrenic gene have a reproductive advantage through enhanced fertility. An advantage arising from lower mortality between birth and the end of the reproductive period was not investigated, but should be examined before we search for other explanations of the apparently stable polymorphism of schizophrenia.

The relationship of pregnancy, vaginal candidiasis and glucose metabolism.

In 72 pregnant women with culture-proved vaginal candidiasis, and an equal number of controls matched for parity, size, stage of gestation and age, the intravenous glucose tolerance curves were compared using Silverstone's method. The results in both study and control groups did not differ and resembled closely those in Silverstone's series. Half the study group were treated using nystatin alone, while the other half also received tolbutamide.

An approach to patient care classification.

Employing the principles of progressive patient care and using data obtained from charts, nurses and resident physicians, 265 patients on the wards of a teaching hospital were classified into one of six optimal levels of care by the resident physicians and also by an outside observer. It was assumed that facilities for the three alternatives to general hospital care, i.e.

CHANGING PATTERNS OF MENTAL HOSPITAL DISCHARGES AND READMISSIONS IN THE PAST TWO DECADES.

The discharge and readmission pattern for the non-organic psychoses (chiefly schizophrenia and manic-depressive psychoses) was studied for three-year periods: immediately before extensive use of modern therapies (1940-42), when electroconvulsive therapy (ECT) alone was extensively used (1950-52), and finally when tranquillizers had been added (1956-58). Patients were followed up for four years after either admission or discharge. The cohort method was used.
