Review Meta AnalysisIncentive spirometry for prevention of postoperative pulmonary complications in upper abdominal surgery.
Upper abdominal surgical procedures are associated with a high risk of postoperative pulmonary complications. The risk and severity of postoperative pulmonary complications can be reduced by the judicious use of therapeutic manoeuvres that increase lung volume. Our objective was to assess the effect of incentive spirometry (IS) compared to no therapy, or physiotherapy including coughing and deep breathing, on all-cause postoperative pulmonary complications and mortality in adult patients admitted for upper abdominal surgery. ⋯ We found no evidence regarding the effectiveness of the use of incentive spirometry for prevention of postoperative pulmonary complications in upper abdominal surgery. This review underlines the urgent need to conduct well-designed trials in this field. There is a case for large randomized trials of high methodological rigour in order to define any benefit from the use of incentive spirometry regarding mortality.

Review Meta AnalysisAlpha blockers prior to removal of a catheter for acute urinary retention in adult men.
Acute urinary retention is a urological emergency in men and requires urgent catheterisation. Any intervention which aims at increasing the rate of a successful trial without a catheter following an acute urinary retention episode would be considered potentially beneficial. Alpha blockers relax prostatic smooth muscle cells thereby decreasing the resistance to urinary flow and by doing so improve urinary symptoms. ⋯ The limited available evidence suggests that alpha blockers increase success rates of TWOC. Alpha blocker side effects are low and comparable to placebo. It is uncertain whether alpha blockers reduce the risk of recurrent urinary retention and need for prostate surgery. The cost effectiveness and recommended duration of alpha blocker treatment after successful TWOC remains unknown. There are a lack of internationally agreed outcome measures for what constitutes successful TWOC. This makes meta-analysis difficult. More randomised clinical trials are needed to address these issues.

Review Meta AnalysisMusic for stress and anxiety reduction in coronary heart disease patients.
Individuals with coronary heart disease (CHD) often suffer from severe distress putting them at greater risk for complications. Music interventions have been used to reduce anxiety and distress and improve physiological functioning in medical patients, however its efficacy for CHD patients needs to be evaluated. ⋯ Music listening may have a beneficial effect on blood pressure, heart rate, respiratory rate, anxiety, and pain in persons with CHD. However, the quality of the evidence is not strong and the clinical significance unclear.Most studies examined the effects of listening to pre-recorded music. More research is needed on the effects of music offered by a trained music therapist.

Review Meta AnalysisNebulized and oral thiol derivatives for pulmonary disease in cystic fibrosis.
Cystic fibrosis is an inherited condition resulting in thickened, sticky respiratory secretions. Respiratory failure, due to recurrent pulmonary infection and inflammation, is the most common cause of mortality. Muco-active therapies (e.g. dornase alfa and nebulized hypertonic saline) may decrease sputum viscosity, increase airway clearance of sputum, reduce infection and inflammation and improve lung function. Thiol derivatives, either oral or nebulized, have shown benefit in other respiratory diseases. Their mode of action is likely to differ according to the route of administration. There are several thiol derivatives, and it is unclear which of these may be beneficial in cystic fibrosis. ⋯ We found no evidence to recommend the use of either nebulized or oral thiol derivatives in people with cystic fibrosis. There are very few good quality trials investigating the effect of these medications in cystic fibrosis, and further research is required to investigate the potential role of these medications in improving the outcomes of people with cystic fibrosis.

Review Meta AnalysisMale circumcision for prevention of heterosexual acquisition of HIV in men.
Male circumcision is defined as the surgical removal of all or part of the foreskin of the penis and may be practiced as part of a religious ritual, as a medical procedure, or as part of a traditional ritual performed as an initiation into manhood. Since the 1980s, over 30 observational studies have suggested a protective effect of male circumcision on HIV acquisition in heterosexual men. In 2002, three randomised controlled trials to assess the efficacy of male circumcision for preventing HIV acquisition in men commenced in Africa. This review evaluates the results of these trials, which analysed the effectiveness and safety of male circumcision for preventing acquisition of HIV in heterosexual men. ⋯ There is strong evidence that medical male circumcision reduces the acquisition of HIV by heterosexual men by between 38% and 66% over 24 months. Incidence of adverse events is very low, indicating that male circumcision, when conducted under these conditions, is a safe procedure. Inclusion of male circumcision into current HIV prevention measures guidelines is warranted, with further research required to assess the feasibility, desirability, and cost-effectiveness of implementing the procedure within local contexts.
