Review Meta AnalysisOral versus intravenous fluoropyrimidines for colorectal cancer.
Patients prefer oral to intravenous (IV) palliative chemotherapy, provided that oral therapy is not less effective. We compared the efficacy and safety of oral and IV fluoropyrimidines for treatment of colorectal cancer (CRC). ⋯ Results of this review should provide confidence that treatment for CRC with most of the oral fluoropyrimidines commonly used in current clinical practice is similarly efficacious to treatment with IV fluoropyrimidines. Treatment with eniluracil with oral 5-FU was associated with inferior PFS and OS among participants treated with palliative intent for CRC, and eniluracil is no longer being developed. Oral and IV fluoropyrimidines have different patterns of side effects; future research may focus on determining the basis for these differences.

ReviewLaparoscopic colposuspension for urinary incontinence in women.
Stress urinary incontinence (SUI) imposes significant health and economic burden on society and the women affected. Laparoscopic colposuspension was one of the first minimal access operations for the treatment of women with SUI, with the presumed advantages of avoiding major incisions, shorter hospital stays and quicker return to normal activities. ⋯ Currently available evidence suggests that laparoscopic colposuspension may be as good as open colposuspension at two years post surgery. However, the newer vaginal sling procedures appear to offer even greater benefits, better objective outcomes in the short term and similar subjective outcomes in the longer term. If laparoscopic colposuspension is performed, the use of two paravaginal sutures appears to be the most effective method. The place of laparoscopic colposuspension in clinical practice should become clearer when there are more data available describing long-term results. A brief economic commentary (BEC) identified three studies suggesting that tension-free vaginal tape (TVT) may be more cost-effective compared with laparoscopic colposuspension but laparoscopic colposuspension may be slightly more cost-effective when compared with open colposuspension after 24 months follow-up.

ReviewElective repeat caesarean section versus induction of labour for women with a previous caesarean birth.
When a woman has had a previous caesarean birth and requires induction of labour for a subsequent pregnancy, two options are available for her care: an elective repeat caesarean and planned induction of labour. Although risks and benefits are associated with both elective repeat caesarean birth and planned induction of labour, current sources of information are limited to non-randomised cohort studies, and studies designed in this way have significant potential for bias. Consequently, any conclusions based on results of these studies are limited in their reliability and should be interpreted with caution. ⋯ Both planned elective repeat caesarean section and planned induction of labour for women with a prior caesarean birth are associated with benefits and harms. Evidence for these care practices has been drawn from non-randomised studies, which are associated with potential bias. Therefore, any results and conclusions presented must be interpreted with caution. Randomised controlled trials are required to provide the most reliable evidence regarding the benefits and harms of both planned elective repeat caesarean section and planned induction of labour for women with a previous caesarean birth.

Review Meta AnalysisProcarbazine, lomustine and vincristine for recurrent high-grade glioma.
Recurrent high-grade glioma (HGG) carries an extremely poor prognosis. There is no current standard of care or guideline-based recommendations. Nitrosourea-based multidrug chemotherapy or PCV - procarbazine, lomustine (CCNU) and vincristine - is one of the treatment options at recurrence. There has been no meta-analysis which looks at the benefits and harms of PCV chemotherapy in adults with recurrent HGG. ⋯ Evidence is based on a single large trial analysis as the other trial was small, with inadequate power to detect survival difference. Chemotherapy-naive patients with HGG at first recurrence when treated with PCV or TMZ have similar survival and time-to-progression outcomes. Adverse events are similar and QoL scores are statistically but not clinically significant between TMZ and PCV. Further RCTs should be conducted with adequate power following CONSORT guidelines with emphasis on QoL outcomes.

Review Meta AnalysisTraditional suburethral sling operations for urinary incontinence in women.
Stress urinary incontinence constitutes a significant health and economic burden to society. Traditional suburethral slings are one of the surgical operations used to treat women with symptoms of stress urinary incontinence. ⋯ Traditional slings seem to be as effective as minimally invasive slings, but had higher rates of adverse effects. This should be interpreted with some caution however, as the quality of evidence for the studies was variable, follow-up short and populations small, particularly for identifying complication rates. Tradional sling procedures appeared to confer a similar cure rate in comparison to open retropubic colposuspension, but the long-term adverse event profile is still unclear. A brief economic commentary (BEC) identified two studies suggesting that traditional slings may be more cost-effective compared with collagen injection but not cost-effective when compared with minimally invasive sling operations. Reliable evidence to clarify whether or not traditional suburethral slings may be better or worse than other surgical or conservative management options is lacking.
