Review Meta AnalysisPersonalised risk communication for informed decision making about taking screening tests.
There is a trend towards greater patient involvement in healthcare decisions. Although screening is usually perceived as good for the health of the population, there are risks associated with the tests involved. Achieving both adequate involvement of consumers and informed decision making are now seen as important goals for screening programmes. Personalised risk estimates have been shown to be effective methods of risk communication. ⋯ There is strong evidence from three trials that personalised risk estimates incorporated within communication interventions for screening programmes enhance informed choices. However the evidence for increasing the uptake of such screening tests with similar interventions is weak, and it is not clear if this increase is associated with informed choices. Studies included a diverse range of screening programmes. Therefore, data from this review do not allow us to draw conclusions about the best interventions to deliver personalised risk communication for enhancing informed decisions. The results are dominated by findings from the topic area of mammography and colorectal cancer. Caution is therefore required in generalising from these results, and particularly for clinical topics other than mammography and colorectal cancer screening.

Primary liver tumours and liver metastases from colorectal carcinoma are the two most common malignant tumours to affect the liver. The liver is second only to the lymph nodes as the most common site for metastatic disease. More than half of the patients with metastatic liver disease will die from metastatic complications. Percutaneous ethanol injection (PEI) causes dehydration and necrosis of tumour cells accompanied by small vessel thrombosis, leading to tumour ischaemia and destruction. ⋯ On the basis of one small randomised trial, it can be concluded that addition of PEI to TACE, as compared with TACE alone, in patients with liver metastases seems to bring no clear benefit in terms of survival and local recurrence. The size of the tumour necrosis was larger in the combined treatment group. No intervention-related mortality or major complications were reported. More trials are needed.

Review Meta AnalysisPelvic floor muscle training added to another active treatment versus the same active treatment alone for urinary incontinence in women.
Pelvic floor muscle training (PFMT) is a first-line conservative treatment for urinary incontinence in women. Other active treatments include: physical therapies (e.g. vaginal cones); behavioural therapies (e.g. bladder training); electrical or magnetic stimulation; mechanical devices (e.g. continence pessaries); drug therapies (e.g. anticholinergics (solifenacin, oxybutynin, etc.) and duloxetine); and surgical interventions including sling procedures and colposuspension. This systematic review evaluated the effects of adding PFMT to any other active treatment for urinary incontinence in women ⋯ This systematic review found insufficient evidence to state whether or not there were additional effects of adding PFMT to other active treatment when compared with the same active treatment alone for urinary incontinence (SUI, UUI or MUI) in women. These results should be interpreted with caution as most of the comparisons were investigated in small, single trials. None of the trials in this review were large enough to provide reliable evidence. Also, none of the included trials reported data on adverse events associated with the PFMT regimen, thereby making it very difficult to evaluate the safety of PFMT.

Review Meta AnalysisSurgical interventions for treating radial head fractures in adults.
Radial head fractures are the most common type of elbow fracture and can severely affect the function of the elbow. There is uncertainty and controversy about when surgery is indicated as well as what type of surgical intervention is best. ⋯ Only tentative conclusions can be drawn from the available evidence in this review. Compared with ORIF, there was some evidence that radial head replacement had better elbow function and fewer adverse events for Mason type III radial head fractures in the short term. However, the evidence is of low quality and it is unknown whether these results would apply in the longer term or more generally. Using biodegradable implants may be as good as metallic implants for fixation of some usually more stable fractures but more evidence is needed to confirm this. There is a need for good quality evidence for addressing the areas of uncertainty for the surgical treatment of radial head fractures.

Review Meta AnalysisHomocysteine-lowering interventions for preventing cardiovascular events.
Cardiovascular disease (including coronary artery disease, stroke and congestive heart failure), is a leading cause of death worldwide. Homocysteine is an amino acid with biological functions in methionine metabolism. A postulated risk factor is elevated circulating total homocysteine levels, which are associated with cardiovascular events. This is an update of a review previously published in 2009. ⋯ This updated Cochrane review found no evidence to suggest that homocysteine-lowering interventions in the form of supplements of vitamins B6, B9 or B12 given alone or in combination should be used for preventing cardiovascular events. Furthermore, there is no evidence suggesting that homocysteine-lowering interventions are associated with an increased risk of cancer.
