Review Meta AnalysisColchicine for alcoholic and non-alcoholic liver fibrosis and cirrhosis.
Alcohol and hepatotropic viruses cause the majority of liver cirrhosis cases in the Western World. Colchicine is an anti-inflammatory and anti-fibrotic medication. Several randomised clinical trials have addressed the question whether colchicine has any efficacy in patients with alcoholic or non-alcoholic fibrosis and cirrhosis. ⋯ Colchicine should not be used for alcoholic, viral, or cryptogenic liver fibrosis or liver cirrhosis outside randomised clinical trials.

Review Meta AnalysisProtein and energy supplementation in elderly people at risk from malnutrition.
Evidence for the effectiveness of nutritional supplements containing protein and energy, which are often prescribed for older people, is limited. Furthermore malnutrition is more common in this age group and deterioration of nutritional status can occur during illness. It is important to establish whether supplementing the diet is an effective way of improving outcomes for older people at risk from malnutrition. ⋯ Supplementation produces a small but consistent weight gain in older people. There may also be a beneficial effect on mortality. However, there was no evidence of improvement in clinical outcome, functional benefit or reduction in length of hospital stay with supplements. Additional data from large-scale multi-centre trials are still required.

Review Meta AnalysisAlpha-glucosidase inhibitors for type 2 diabetes mellitus.
Alpha-glucosidase inhibitors such as acarbose or miglitol, have the potential to improve glycemic control in type 2 diabetes mellitus. The true value of these agents, especially in relation to diabetes related mortality and morbidity, has never been investigated in a systematic literature review and meta-analysis. ⋯ It remains unclear whether alpha-glucosidase inhibitors influence mortality or morbidity in patients with type 2 diabetes. Conversely, they have a significant effect on glycemic control and insulin levels, but no statistically significant effect on lipids and body weight. These effects are less sure when alpha-glucosidase inhibitors are used for a longer duration. Acarbose dosages higher than 50 mg TID offer no additional effect on glycated hemoglobin but more adverse effects instead. Compared to sulphonylurea, alpha-glucosidase inhibitors lower fasting and post-load insulin levels and have an inferior profile regarding glycemic control and adverse effects.

Review Meta AnalysisTaxane containing regimens for metastatic breast cancer.
It is generally accepted that taxanes are among the most active chemotherapy agents in the management of metastatic breast cancer. ⋯ When all trials are considered, taxane-containing regimens appear to improve overall survival, time to progression and overall response in women with metastatic breast cancer. The degree of heterogeneity encountered indicates that taxane-containing regimens are more effective than some, but not all non-taxane-containing regimens.

Although widely accepted as an appropriate immunosuppressive therapy, the efficacy of glucocorticosteroid treatment has only rarely been tested in controlled studies. ⋯ Limited evidence from randomised controlled trials suggests that corticosteroid treatment offers significant short-term benefit in myasthenia gravis compared with placebo. This supports the conclusions of observational studies and expert opinion. Limited evidence from randomised controlled trials does not show any difference in efficacy between corticosteroids and either azathioprine or intravenous immunoglobulin.
