Three-year follow-up of Pawtucket Heart Health's community-based weight loss programs.

PURPOSE: The purpose of the study was to evaluate the effectiveness of a community-based weight loss program. DESIGN: A questionnaire was administered by telephone to subjects one to three years following participation in a weight loss program. SETTING: The study took place in Pawtucket, Rhode Island. The Pawtucket Heart Health Program is part of this setting. SUBJECTS: A stratified sample of 400 subjects was randomly selected from 2,186 people who participated in weight loss programs between 1985 and 1987. A total of 285 subjects completed the questionnaire; 229 subjects provided sufficient information to be included in the study. INTERVENTION: The subjects participated in community-based and worksite-based weight loss programs. MEASURES: Self-reported heights and weights before and after intervention and demographic data were collected. Desirable body weight and Garrow's health risk classifications were calculated. RESULTS: Overall, there was a 3.2% reduction in body weight between time of entrance into weight loss programs and time of interview. Eighty percent of the participants lost weight in the program; mean weight loss was 11 pounds. At time of follow-up interview one to three years later, 65% of subjects weighed less than at entrance into the community programs; on average, subjects weighed six pounds less. Sixty-nine percent of the sample was above 20% desirable body weight at entrance and 26% of this group lost enough weight to lower their health risk category. CONCLUSIONS: Weight loss in this community-based program compares favorably with those reported by more intense and expensive clinic-bound programs.(ABSTRACT TRUNCATED AT 250 WORDS)

Riboflavin status of nutritionally supported multiple-trauma accident patients.

This study evaluates riboflavin status of multiple-trauma accident patients receiving nutritional support. Riboflavin excretion, erythrocyte glutathione reductase (EGR-AC), erythrocyte riboflavin (ERC-B2), nitrogen balance and riboflavin, and nitrogen and energy intake were assessed periodically throughout the study. Mean intakes of nitrogen, energy, and riboflavin were less than recommended. All patients but one were in negative nitrogen balance; however, patients retained riboflavin except when nitrogen and energy intakes were very low. EGR-AC values were within normal range and did not reflect changes in riboflavin retention. ERC-B2 values were also within normal range but decreased over time in patients with the largest riboflavin excretion and most negative nitrogen balance. ERC-B2 in combination with riboflavin intake and excretion data may offer a suitable method for assessing riboflavin status in multiple-trauma patients.

An audit of surgery for seventy-one primary parotid tumours.

Seventy-one consecutive patients who presented with lumps in the parotid gland over an eight year period (1981-1989) were analysed. Two-thirds of the patients presented with a history of swelling for over one year, while a quarter (24%) had a parotid mass for over five years at initial referral. The pathology of these masses was diverse, with pleomorphic adenoma being the commonest (64%). Superficial parotidectomy was the commonest procedure employed (50/71) with local excision being performed only in the initial part of our series (15/71). There were five cases of permanent facial palsy, four following radical resection for malignancy. Tumour recurrence rate was 2/15 (13%) in cases treated by local excision while none of the 50 patients treated by superficial parotidectomy had tumour recurrence at a mean follow-up of five years. Only three patients developed Frey's Syndrome. It is recommended that increased community awareness of early referral of a parotid mass is necessary, as surgical treatment in the form of superficial parotidectomy, which is the ideal procedure for such lumps, carries minimal morbidity when performed by a surgeon with a special interest in parotid surgery.

Use of sodium nitroprusside and dopamine hydrochloride in the postoperative cardiac patient.

Effective postoperative nursing care of the cardiac surgery patient receiving combined drug infusion of dopamine HCl and SNP requires awareness of many critical factors. Among these are: (1) understanding of cardiac physiology with emphasis on the concepts of myocardial oxygen consumption vs. availability; (2) basic pharmacologic functions of dopamine HCl and SNP, both singly and combined; (3) importance of maintaining intravascular volume at optimum levels; and (4) awareness that constant nursing observations and reassessments are essential.

Relaxation training and response to cardiac catheterization: a pilot study.

This pilot study evaluated the effects of relaxation-via-letting-go training on patients' state anxiety, observer-reported distress, and self-reported distress during cardiac catheterization. The sample consisted of 30 adults, 15 subjects in the relaxation training group and 15 subjects in the control group. A comparison of the control and relaxation training groups on the demographic variables of age and education, the preintervention variables of state anxiety and worry about the procedure, and number of days in the hospital prior to catheterization showed no differences between the groups. Relaxation training subjects did not indicate less anxiety prior to catheterization nor were they seen as less distressed during the procedure than control subjects. In addition, relaxation subjects did not report having less distress than control subjects.
