The effect of nutritional intervention in elderly subjects residing in group-living for the demented.

OBJECTIVES: We studied the nutritional status and the effects of nutritional intervention on body weight, cognition and activities of daily life (ADL)-function in demented individuals. DESIGN: Controlled non-randomised study. SETTING: Group-living for demented elderly (GLD), ie community assisted housing. SUBJECTS AND INTERVENTIONS: Twenty-two residents living in one of two units (GLD-I), received oral liquid supplements (1720 kJ/410 kcal/day) and the personnel of the GLD-I were given nutritional education. Fourteen residents in the other unit (GLD-C) served as controls. After 6 months 21 (83 (4) y, 81% women) and 12 (85 (4) y, 100% women) of the participants, respectively, were re-examined according to body mass index (BMI, kg/m2), cognitive function (Mini Mental State Examination (MMSE, 0-30 p) and Clinical Dementia Rating Scale (CDR) and the Katz' ADL index. RESULTS: Body mass index (BMI) < or =20 was found in 19% of the participants and 44% had BMI< or =23. BMI correlated with MMSE (r=0.43, P<0.01). The weight of the residents in the intervention group increased by 3.4 (3) kg (P=0.001) at follow-up, whereas the weight remained unchanged in the control group. The cognitive function was low at the start in both groups, ie MMSE approximately 9 and no apparent positive effect of the nutritional intervention was seen. In addition, the ADL functions appeared to deteriorate in both groups. CONCLUSIONS: Being underweight was common among demented elderly in group-living and was related to low cognitive capacity. Five months of oral supplementation, along with education of personnel, was followed by a weight gain. In this study the nutritional treatment did not affect the rate of decline in cognitive function or Katz' ADL index. SPONSORSHIP: Supported by grants from the Swedish National Board of Health and Social Welfare. Semper Foods AB provided the liquid supplements.

A 6-hour working day--effects on health and well-being.

The effect of the total amount of work hours and the benefits of a shortening is frequently debated, but very little data is available. The present study compared a group (N = 41) that obtained a 9 h reduction of the working week (to a 6 h day) with a comparison group (N = 22) that retained normal work hours. Both groups were constituted of mainly female health care and day care nursery personnel. The experimental group retained full pay and extra personnel were employed to compensate for loss of hours. Questionnaire data were obtained before and 1 year after the change. The data were analyzed using a two-factor ANOVA with the interaction term year*group as the main focus. The results showed a significant interaction of year*group for social factors, sleep quality, mental fatigue, and heart/respiratory complaints, and attitude to work hours. In all cases the experimental group improved whereas the control group did not change. It was concluded that shortened work hours have clear social effects and moderate effects on well-being.

The childbirth experience: a study of 295 new mothers.

BACKGROUND: The childbirth experience is multidimensional, and therefore difficult to describe and explain. Studies of it have produced inconsistent findings, and the phenomenon is often confused with satisfaction with the care provided. This study aimed to clarify different aspects of the birth experience, and to identify factors that could explain the variation in women's overall assessment of it. METHODS: All Swedish-speaking women in a large city who gave birth during a two-week period in 1994 were given a questionnaire one day after the birth, and 295 (91%) of the questionnaires were returned. Information about the labor process and medical interventions was collected from hospital records. RESULTS: Women usually experienced severe pain and various degrees of anxiety, and most were seized with panic for a short time or some part of their labor. Despite these negative feelings, most women felt greatly involved in the birth process, were satisfied with their own achievement, and thought they had coped better than expected. The overall experience was assessed as positive by 77 percent of women and negative by 10 percent. No statistical difference was observed between primiparas and multiparas in total birth experience, and few differences in the specific aspects of the birth. Of the 38 variables tested in regression analysis, the six that contributed to explaining women's overall birth experience were support from the midwife (sensitivity to needs), duration of labor, pain, expectations of the birth, involvement and participation in the birth process, and surgical procedures (emergency cesarean section, vacuum extraction, forceps, episiotomy). CONCLUSIONS: The study showed that negative and positive feelings can coexist, thus confirming the multidimensional character of the birth experience. Women's assessment of their childbirth is influenced by both physical and psychosocial factors, highlighting the importance of a comprehensive approach to care in labor.

Cost effectiveness of primary stroke prevention in atrial fibrillation: Swedish national perspective.

OBJECTIVE: To assess the potential effects of primary prevention with anticoagulants or aspirin in atrial fibrillation on Swedish population. DESIGN: Analysis of cost effectiveness based on the following assumptions: about 83,000 people have atrial fibrillation in Sweden, of whom 22,000 would be potential candidates for treatment with anticoagulants and 55,000 for aspirin treatment; the annual 5% stroke rate is reduced by 64% (with anticoagulants) and 25% (with aspirin); incidence of intracranial haemorrhage of 0.3%, 1.3%, or 2.0% per year; direct and indirect costs of a stroke of Kr180,000 and Kr90,000; estimated annual cost of treatment is Kr5030 for anticoagulants and Kr100 for aspirin. SETTING: Total Swedish population. MAIN OUTCOME MEASURES: Direct and indirect costs of stroke saved, number of strokes prevented, and cost of preventive treatment. RESULTS: Depending on the rate of haemorrhagic complications 34 to 83 patients would need to be treated annually with anticoagulants to prevent one stroke; 83 patients would need to be treated with aspirin. Giving anticoagulant treatment only would reduce costs by Kr60 million if the incidence of intracranial haemorrhage were 0.3% but would imply a net expense if the complication rate exceeded 1.3%. The total savings from giving anticoagulant (22,000 patients) and aspirin (55,000 patients) treatment would be Kr175 million per year corresponding to 2 million pounds per million inhabitants each year. CONCLUSIONS: Treatment with anticoagulants and, if contraindications exist, with aspirin is cost effective provided that the risk of serious haemorrhage complications due to anticoagulants is kept low.

Conservative surgery for mitral valve prolapse with regurgitation: clinical follow-up and noninvasive assessment.

To evaluate the result of mitral valve repair in pure regurgitation due to mitral valve prolapse with or without chordal rupture, 11 patients were followed noninvasively for 2.0 to 3.5 years and clinically for at least 5 years in a prospective study. The patients were operated upon before ominous signs of left ventricular dysfunction appeared, all patients being in functional class III, with an ejection fraction of at least 0.50 and mean velocity of circumferential fibre shortening above 1.0. There was no operative mortality. No thrombo-embolic episodes occurred during follow-up. Ten of the 11 patients were alive 5 years postoperatively. One patient died 9 months after the initial repair shortly after reoperation for mitral and tricuspid regurgitation. The other patients all showed definite clinical improvement. Confirming the experience of others, the two patients with ruptured chordae to the anterior mitral leaflet and the only patient with a thick anterior mitral leaflet all had moderate mitral regurgitation postoperatively. Complete repair of mitral valve prolapse is feasible and gives a good functional result of long duration. The results of this study support early mitral repair when complete restoration of ventricular size and function is still possible.
