Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular diseases in the general population. While numerous treatments have been adopted for different disease stages, there is no option other than amputation for patients presenting with critical limb ischaemia (CLI), unsuitable for rescue or reconstructive intervention. ⋯ Despite some positive results regarding rest-pain relief, ulcer healing and amputations, there is no conclusive evidence based on this meta-analysis of the long-term effectiveness and safety of different prostanoids in patients with CLI. Further well-conducted, high quality randomised double-blinded trials should be performed.

Review Meta AnalysisQuetiapine versus other atypical antipsychotics for schizophrenia.
In many countries of the industrialised world second generation ('atypical') antipsychotic drugs have become the first line drug treatment for people with schizophrenia. It is not clear how the effects of the various second generation antipsychotic drugs differ. ⋯ Best available evidence from trials suggests that most people who start quetiapine stop taking it within a few weeks. Comparisons with amisulpride, aripiprazole, sertindole and zotepine do not exist. Most data that has been reported within existing comparisons are of very limited value because of assumptions and biases within them. There is much scope for further research into the effects of this widely used drug.

In an effort to improve outcomes of in-vitro fertilisation cycles the use of growth hormone has been considered. Improving the outcomes of in-vitro fertilisation is especially important for subfertile women who are considered 'poor responders'. ⋯ Although the use of growth hormone in poor responders has been found to show a significant improvement in live birth rates, we were unable to identify which sub-group of poor responders would benefit the most from adjuvant growth hormone. The result needs to be interpreted with caution, the included trials were few in number and small sample size. Therefore, before recommending growth hormone adjuvant in in-vitro fertilisation further research is necessary to fully define its role.

Review Meta AnalysisReducing uncertainties about the effects of chemoradiotherapy for cervical cancer: individual patient data meta-analysis.
After a 1999 National Cancer Institute (NCI) clinical alert was issued, chemoradiotherapy has become widely used in treating women with cervical cancer. Two subsequent systematic reviews found that interpretation of the benefits was complicated and some important clinical questions were unanswered. ⋯ These results endorse the recommendations of the NCI alert, but also demonstrate their applicability to all women and a benefit of non-platinum based chemoradiotherapy. Furthermore, although these results suggest an additional benefit from adjuvant chemotherapy this requires testing in RCTs.

Review Meta AnalysisSurgical sealant for preventing air leaks after pulmonary resections in patients with lung cancer.
Postoperative air leak is a frequent complication after pulmonary resection for lung cancer. It may cause serious complications, such as empyema, or prolong the need for chest tube and hospitalization. Different types of surgical sealants have been developed to prevent or to reduce postoperative air leaks. A systematic review was therefore undertaken to evaluate the evidence on their effectiveness. ⋯ Surgical sealants reduce postoperative air leaks and time to chest drain removal but this reduction is not always associated with a reduction in length of postoperative hospital stay. Therefore, systematic use of surgical sealants with the objective of reducing hospital stay cannot be recommended at the moment. More and larger randomized controlled clinical trials are needed.
