Review Meta AnalysisBlood pressure lowering efficacy of potassium-sparing diuretics (that block the epithelial sodium channel) for primary hypertension.
Potassium-sparing diuretics, which block the epithelial sodium channel (ENaC), are widely prescribed for hypertension as a second-line drug in patients taking other diuretics (e.g. thiazide diuretics) and much less commonly prescribed as monotherapy. Therefore, it is essential to determine the effects of ENaC blockers on blood pressure (BP), heart rate and withdrawals due to adverse effects (WDAEs) when given as a first-line or second-line therapy. ⋯ ENaC blockers do not have a statistically or clinically significant BP lowering effect at low doses but trials at higher doses are not available. The review did not provide a good estimate of the incidence of harms associated with ENaC blockers.

Review Meta AnalysisInformation provision for stroke patients and their caregivers.
Research shows that stroke patients and their families are dissatisfied with the information provided and have a poor understanding of stroke and associated issues. ⋯ There is evidence that information improves patient and carer knowledge of stroke, aspects of patient satisfaction, and reduces patient depression scores. However, the reduction in depression scores was small and may not be clinically significant. Although the best way to provide information is still unclear there is some evidence that strategies that actively involve patients and carers and include planned follow-up for clarification and reinforcement have a greater effect on patient mood.

Review Meta AnalysisSurgical treatment of fibroids for subfertility.
Fibroids are the most common benign tumours of the female genital tract and are associated with numerous clinical problems including a possible negative impact on fertility. In women requesting preservation of fertility, fibroids can be surgically removed (myomectomy) by laparotomy, laparoscopically or hysteroscopically depending on the size, site and type of fibroid. Myomectomy is however a procedure that is not without risk and can result in serious complications. It is therefore essential to determine whether such a procedure can result in an improvement in fertility and, if so, to then determine the ideal surgical approach. ⋯ There is currently insufficient evidence from randomised controlled trials to evaluate the role of myomectomy to improve fertility. Regarding the surgical approach to myomectomy, current evidence from two randomised controlled trials suggests there is no significant difference between the laparoscopic and open approach regarding fertility performance. This evidence needs to be viewed with caution due to the small number of studies. Finally, there is currently no evidence from randomised controlled trials regarding the effect of hysteroscopic myomectomy on fertility outcomes.

Review Meta AnalysisExercise for the management of cancer-related fatigue in adults.
Cancer-related fatigue is recognised as an important symptom associated with cancer and its treatment. A number of studies have investigated the effects of physical activity in reducing cancer-related fatigue. This is an updated version of the original Cochrane review published in The Cochrane Library (2008, Issue 1). The original review identified some benefits of physical activity on fatigue in cancer both during and after adjuvant treatment. We identified a number of limitations in the evidence, providing clear justification for an updated review. ⋯ The findings of the updated review have enabled a more precise conclusion to be made in that aerobic exercise can be regarded as beneficial for individuals with cancer-related fatigue during and post-cancer therapy, specifically those with solid tumours. Further research is required to determine the optimal type, intensity and timing of an exercise intervention.

Review Meta AnalysisHorse chestnut seed extract for chronic venous insufficiency.
Conservative therapy of chronic venous insufficiency (CVI) consists largely of compression treatment. However, this often causes discomfort and has been associated with poor compliance. Therefore, oral drug treatment is an attractive option. This is an update of a Cochrane review first published in 2002 and updated in 2004, 2006, 2008 and 2010. ⋯ The evidence presented suggests that HCSE is an efficacious and safe short-term treatment for CVI. However, several caveats exist and larger, definitive RCTs are required to confirm the efficacy of this treatment option.
