Review Meta AnalysisFixed dose subcutaneous low molecular weight heparins versus adjusted dose unfractionated heparin for venous thromboembolism.
Low molecular weight heparins (LMWHs) have been shown to be effective and safe in preventing venous thromboembolism (VTE). They may also be effective for the initial treatment of VTE. This is an update of a Cochrane review first published in 1999 and previously updated in 2004. ⋯ Fixed dose LMWH is more effective and safer than adjusted dose UFH for the initial treatment of VTE. Compared to UFH, LMWH significantly reduced the incidence of thrombotic complications, the occurrence of major haemorrhage during initial treatment and overall mortality at follow up.

Review Meta AnalysisInterventions for nausea and vomiting in early pregnancy.
Nausea, retching and vomiting are very commonly experienced by women in early pregnancy. There are considerable physical and psychological effects on women who experience these symptoms. This is an update of a review of interventions for nausea and vomiting in early pregnancy previously published in 2003. ⋯ Given the high prevalence of nausea and vomiting in early pregnancy, health professionals need to provide clear guidance to women, based on systematically reviewed evidence. There is a lack of high-quality evidence to support that advice. The difficulties in interpreting the results of the studies included in this review highlight the need for specific, consistent and clearly justified outcomes and approaches to measurement in research studies.

Review Meta AnalysisInteractive computer-based interventions for sexual health promotion.
Sexual health promotion is a major public health challenge; there is huge potential for health promotion via technology such as the Internet. ⋯ ICBI are effective tools for learning about sexual health, and they also show positive effects on self-efficacy, intention and sexual behaviour. More research is needed to establish whether ICBI can impact on biological outcomes, to understand how interventions might work, and whether they are cost-effective.

Review Meta AnalysisChinese herbal medicine for subfertile women with polycystic ovarian syndrome.
Polycystic ovarian syndrome (PCOS) is one of the most common reproductive endocrinology abnormalities, affecting 5% to 10% of women of reproductive age. Western medicines, such as oral contraceptives and insulin sensitizers, have been widely used to improve the symptoms and signs for PCOS. Recently, many studies have been published considering Chinese herbal medicine (CHM) as an alternative treatment for women with PCOS. ⋯ There is limited evidence that the addition of CHM to clomiphene is associated with improved clinical pregnancy outcomes and no other evidence of any other effect. The methodology of RCTs was not adequately reported by primary studies.
