ReviewPharmacological interventions for primary sclerosing cholangitis: an attempted network meta-analysis.
Primary sclerosing cholangitis is a chronic cholestatic liver disease that is associated with both hepatobiliary and colorectal malignancies, which can result in liver cirrhosis and its complications. The optimal pharmacological treatment for patients with primary sclerosing cholangitis remains controversial. ⋯ Evidence is currently insufficient to show differences in effectiveness measures such as mortality, health-related quality of life, cirrhosis, or liver transplantation between any active pharmacological intervention and no intervention. However, trials were at high risk of bias and included small numbers of participants, had short follow-up periods, and reported few clinical outcomes. An urgent need exists to identify an effective medical treatment for primary sclerosing cholangitis through well-designed RCTs with adequate follow-up that aim to identify differences in outcomes important to people with primary sclerosing cholangitis.

Review Meta AnalysisOnce-daily versus multiple-daily dosing with intravenous aminoglycosides for cystic fibrosis.
People with cystic fibrosis, who are chronically colonised with the organism Pseudomonas aeruginosa, often require multiple courses of intravenous aminoglycoside antibiotics for the management of pulmonary exacerbations. The properties of aminoglycosides suggest that they could be given in higher doses less often. This is an update of a previously published review. ⋯ Once- and three-times daily aminoglycoside antibiotics appear to be equally effective in the treatment of pulmonary exacerbations of cystic fibrosis. There is evidence of less nephrotoxicity in children.

Review Meta AnalysisGlucocorticoid supplementation during ovarian stimulation for IVF or ICSI.
Ovarian response to stimulation during in-vitro fertilisation (IVF) and intra-cytoplasmic sperm injection (ICSI) plays an important role in determining live birth rates. Adjuvant treatments during ovarian stimulation that have different modes of action have been used to improve ovarian response to stimulation and outcome of IVF. Glucocorticoids (GCs) are a class of steroid hormones that have been used either alone or in combination with other stimulatory regimens in order to improve folliculogenesis and pregnancy rates. However, considerable uncertainty remains over whether administration of glucocorticoid during ovarian stimulation until oocyte recovery is superior to no glucocorticoid in improving live birth rates in women undergoing IVF/ICSI. ⋯ The safety and effectiveness of glucocorticoid administration in women undergoing controlled ovarian hyperstimulation for IVF/ICSI cycles (until the day of oocyte retrieval) is unclear due to the small number of studies and low event rates. Whilst glucocorticoids possible increase the clinical pregnancy rate, there may be little or no impact on live birth rate. More research is needed.

Review Meta AnalysisOral nonsteroidal anti-inflammatory drugs for fibromyalgia in adults.
Oral nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used in the treatment of pain in fibromyalgia, despite being considered not to be effective. ⋯ There is only a modest amount of very low-quality evidence about the use of NSAIDs in fibromyalgia, and that comes from small, largely inadequate studies with potential risk of bias. That bias would normally be to increase the apparent benefits of NSAIDs, but no such benefits were seen. Consequently, NSAIDs cannot be regarded as useful for treating fibromyalgia.

Review Meta AnalysisL-carnitine for cognitive enhancement in people without cognitive impairment.
Safe interventions to enhance cognitive function in cognitively healthy people would be very valuable for several reasons, including a better quality of life and professional success. While L-carnitine has been reported to enhance cognitive function in some conditions, its efficacy is disputed. The evidence of its efficacy for cognitively healthy people has not previously been systematically reviewed. ⋯ Due to the limited number of included trials, short-term treatment, and inadequate reporting, we were unable to draw any conclusions about the efficacy or safety of L-carnitine for cognitive enhancement in healthy adults. Well-designed, randomised, placebo-controlled trials of L-carnitine for cognition enhancement in cognitively healthy people, with large samples and relatively long-term follow-up, are still needed.
