Review Meta AnalysisRecombinant human insulin-like growth factor I (rhIGF-I) for the treatment of amyotrophic lateral sclerosis/motor neuron disease.
Recombinant human insulin-like growth factor I (rhIGF-I) is a possible disease modifying therapy for amyotrophic lateral sclerosis (ALS, which is also known as motor neuron disease (MND)). ⋯ Meta-analysis revealed a significant difference in favour of rhIGF-I treatment; however, the quality of the evidence from the two included trials was low. A third study showed no difference between treatment and placebo. There is no evidence for increase in survival with IGF1. All three included trials were at high risk of bias.

Review Meta AnalysisTopical preparations for preventing stretch marks in pregnancy.
Striae gravidarum (stretch marks developing during pregnancy) occur in 50% to 90% of women. They appear as red or purple lines or streaks that fade slowly to leave pale lines or marks on the skin. The abdomen, breasts and thighs are commonly affected. The exact cause of stretch marks is unclear and no preparation has yet been shown to be effective in preventing the development of stretch marks. They are a source of significant anxiety for women, impacting on their quality of life. ⋯ We found no high-quality evidence to support the use of any of the topical preparations in the prevention of stretch marks during pregnancy. There is a clear need for robust, methodologically rigorous randomised trials involving larger sample sizes to evaluate the effects of topical preparations on the development of stretch marks in pregnancy. In addition, it is important that preparations commonly used by women to prevent and treat stretch marks are evaluated within the context of robust, methodologically rigorous and adequately powered randomised trials.

Review Meta AnalysisClomiphene citrate in combination with gonadotropins for controlled ovarian stimulation in women undergoing in vitro fertilization.
Gonadotropins are the most commonly used medication for controlled ovarian stimulation in in vitro fertilization (IVF). However, they are expensive, invasive and are associated with risk of ovarian hyperstimulation syndrome (OHSS). With recent calls for patient friendly IVF, there has been an interest in the use of clomiphene citrate with or without gonadotropins to reduce the burden of injections. However, it is not known whether regimens using clomiphene are at least as effective as gonadotropins alone. ⋯ There was no evidence to indicate that clomiphene with gonadotropins (with or without GnRH antagonist) differed significantly from gonadotropins in GnRH agonist protocols for women undergoing IVF treatment, in terms of live births or pregnancy rates. Meanwhile, use of clomiphene led to a reduction in the incidence of OHSS. However, these results were based on data from a small number of underpowered randomised trials with few participants. Hence there was insufficient evidence to recommend use of clomiphene citrate in routine IVF practice. Larger trials with adequate power are required.

Review Meta AnalysisExercise for the management of cancer-related fatigue in adults.
Cancer-related fatigue is recognised as an important symptom associated with cancer and its treatment. A number of studies have investigated the effects of physical activity in reducing cancer-related fatigue. This is an updated version of the original Cochrane review published in The Cochrane Library (2008, Issue 1). The original review identified some benefits of physical activity on fatigue in cancer both during and after adjuvant treatment. We identified a number of limitations in the evidence, providing clear justification for an updated review. ⋯ The findings of the updated review have enabled a more precise conclusion to be made in that aerobic exercise can be regarded as beneficial for individuals with cancer-related fatigue during and post-cancer therapy, specifically those with solid tumours. Further research is required to determine the optimal type, intensity and timing of an exercise intervention.

Review Meta AnalysisHorse chestnut seed extract for chronic venous insufficiency.
Conservative therapy of chronic venous insufficiency (CVI) consists largely of compression treatment. However, this often causes discomfort and has been associated with poor compliance. Therefore, oral drug treatment is an attractive option. This is an update of a Cochrane review first published in 2002 and updated in 2004, 2006, 2008 and 2010. ⋯ The evidence presented suggests that HCSE is an efficacious and safe short-term treatment for CVI. However, several caveats exist and larger, definitive RCTs are required to confirm the efficacy of this treatment option.
