Review Meta AnalysisFluticasone at different doses for chronic asthma in adults and children.
Inhaled fluticasone propionate (FP) is a high-potency inhaled corticosteroid used in the treatment of asthma. ⋯ We have not found evidence of a pronounced dose response in FEV1 with increasing doses of fluticasone. The number of studies contributing to our primary outcomes was low. At dose ratios of 1:2, there are statistically significant differences in favour of the higher dose in morning peak flow across the low dose range. The clinical impact of these differences is open to interpretation. Patients with moderate disease achieve similar levels of asthma control on medium doses of fluticasone (400 to 500 microg/day) as they do on high doses (800 to 1000 microg/day). More work in severe asthma would help to confirm that doses of FP above 500 microg/day confer greater benefit in this subgroup than doses of around 200 microg/day. In oral corticosteroid-dependent asthmatics, reductions in prednisolone requirement may be gained with FP 2000 microg/day.

Review Meta AnalysisElectromechanical and robot-assisted arm training for improving arm function and activities of daily living after stroke.
Electromechanical and robot-assisted arm training devices are used in rehabilitation and might help to improve arm function after stroke. ⋯ Patients who receive electromechanical and robot-assisted arm training after stroke are not more likely to improve their activities of daily living, but arm motor function and strength of the paretic arm may improve. However, the results must be interpreted with caution because there were variations between the trials in the duration, amount of training and type of treatment, and in the patient characteristics.

Review Meta AnalysisPelvic floor muscle training for prevention and treatment of urinary and faecal incontinence in antenatal and postnatal women.
About a third of women have urinary incontinence and up to a tenth have faecal incontinence after childbirth. Pelvic floor muscle training is commonly recommended during pregnancy and after birth both for prevention and treatment of incontinence. ⋯ There is some evidence that PFMT in women having their first baby can prevent urinary incontinence in late pregnancy and postpartum. In common with older women with stress incontinence, there is support for the widespread recommendation that PFMT is an appropriate treatment for women with persistent postpartum urinary incontinence. It is possible that the effects of PFMT might be greater with targeted rather than population-based approaches and in certain groups of women (for example primiparous women; women who had bladder neck hypermobility in early pregnancy, a large baby, or a forceps delivery). These and other uncertainties, particularly long-term effectiveness, require further testing.

Review Meta AnalysisPackage of care for active management in labour for reducing caesarean section rates in low-risk women.
Approximately 15% of women have caesarean sections (CS) and while the rate varies, the number is increasing in many countries. This is of concern because higher CS rates do not confer additional health gain but may adversely affect maternal health and have implications for future pregnancies. Active management of labour has been proposed as a means of reducing CS rates. This refers to a package of care including strict diagnosis of labour, routine amniotomy, oxytocin for slow progress and one to one support in labour. ⋯ Active management is associated with small reductions in the CS rate, but it is highly prescriptive and interventional. It is possible that some components of the active management package are more effective than others. Further work is required to determine the acceptability of active management to women in labour.

Review Meta AnalysisProcaine treatments for cognition and dementia.
Procaine is a controversial substance which has been used for "antiageing" effects including cognitive improvement for more than 50 years.Preparations which contain procaine as a component are claimed to prevent, reverse and interrupt dementia. Several products are widely promoted and can be purchased "over the counter" outside the US and via the Internet. Procaine preparations are said to be readily available in over 70 countries and to be used by more than 100 million people. ⋯ This review suggests that the evidence for detrimental effects of procaine and its preparations is stronger than the evidence for benefit in preventing and/or treating dementia or cognitive impairment.There is some evidence from older studies that procaine preparations might improve memory in persons without cognitive impairment. However, the clear evidence of side effects suggests that the risks might outweigh the benefits. In the light of this, the strong marketing claims for procaine preparations should be withdrawn until trials of adequate size, duration and quality have been conducted.
