Evidence of the effect of exercise on bone loss comes mainly from studies in voluntary postmenopausal women, and no population-based, long-term interventions have been performed. The purpose of this population-based, randomized, controlled trial was to determine the effect of long-term impact exercise on bone mass at various skeletal sites in elderly women with low bone mineral density (BMD) at the radius and hip. Participants ( n =160) were randomly assigned to 30 months either of supervised and home-based impact exercise training or of no intervention. The primary outcome measures were femoral neck, trochanter and total hip BMD, and the secondary outcomes were bone density measures at the radius and calcaneum. Outcomes were assessed at baseline, 12 months and 30 months using blinded operators. The analyses were performed on an intention-to-treat analysis. Mean femoral neck and trochanter BMD decreased in the control group [–1.1%, 95% confidence interval (CI) –0.1% to –2.1% and –1.6%, 95% CI –0.4% to –2.7%], while no change occurred in the exercise group. Mean trochanter BMC decreased more in the control group (–7.7%, 95% CI –9.7% to –5.6% vs. –2.9%, 95% CI –5.3 to –0.9). There were six falls that resulted in fractures in the exercise group and 16 in the control group during the 30-month intervention ( P =0.019). A significant bone loss occurred in both groups at the radius and calcaneum. In multivariate analysis, weight gain was associated with increased BMD and BMC at all femur sites both in the exercise group and in the pooled groups. In conclusion, impact exercise had no effect on BMD, while there was a positive effect on BMC at the trochanter. Exercise may prevent fall-related fractures in elderly women with low bone mass.There was no conflict of interest.  相似文献

This paper explores some modern concepts of teaching and learning, including cognitive theory, the zone of proximal development, constructivism, andragogy and learning styles and describes how they have informed the development of an undergraduate orthodontic curriculum. The changes described include student-centred learning, guided self-learning, and the incorporation of problem-based learning concepts. The details of the problem-based learning programme are described together with results of student feedback on the change in teaching and learning style.  相似文献

Aim To determine the efficacy of diphenhydramine against cough due to respiratory infection or irritation in patients/subjects without comorbidities. Method Two reviewers independently identified English language studies, searching on: clinical trials, randomized, diphenhydramine (OR dimenhydrinate), antitussive agents, cough (combine using AND). Sources were: Medline (1966–2005), Embase (1980–2005), Cochrane and references from retrieved articles. Two other reviewers, blinded to study origin selected studies, inclusion criteria being: diphenhydramine monotherapy against placebo, double-blinded, randomized, clinical trial, intention-to-treat, dropout information. The blinded reviewers evaluated the selected studies on a quality scale. Results Eleven articles were identified, 7 were rejected (4 not placebo controlled, 2 had no diphenhydramine, 1 not blinded), leaving 4 articles, that were included in the evaluation and scored 20, 21, 25 and 26 out of a maximum of 32. In these selected studies, a total of 162 people were examined, 65 on diphenhydramine, 63 on placebo and 34 in a crossover setting. There was a total of 13 dropouts. The crossover studies demonstrated significant effect; 27–56% reduction in 20 healthy volunteers and 21–26% reduction in 13 patients (originally 14, one outlier left out), whereas the active versus placebo studies did not. Conclusion In spite of the 60 years that the substance has been on the market, only few studies have properly evaluated the effect of diphenhydramine against cough. Presumptions about efficacy of diphenhydramine against cough in humans are not univocally substantiated in literature.  相似文献
