Cholelithiasis is a common disease of the biliary tract. Chinese medicinal herbs are being used widely as an alternative treatment in people with cholelithiasis, but their beneficial or harmful effects have not been assessed systematically. ⋯ This review reveals no strong evidence that the analysed Chinese medicinal herbs have any beneficial effects on asymptomatic or mild-to-moderate cholelithiasis. Definitive conclusions will require much better designed randomised trials to reduce risk of bias and allow detailed assessment of clinical outcomes.

The associations of low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B (apoB) levels with the risk of cardiovascular events among patients treated with statin therapy have not been reliably documented. ⋯ Among statin-treated patients, on-treatment levels of LDL-C, non-HDL-C, and apoB were each associated with risk of future major cardiovascular events, but the strength of this association was greater for non-HDL-C than for LDL-C and apoB.

This is an update of a Cochrane review first published in 2001. At that stage there was insufficient evidence to recommend statins for the prevention of Alzheimer's disease (AD). The scope of this review has been expanded to include all forms of dementia. ⋯ There is good evidence from RCTs that statins given in late life to individuals at risk of vascular disease have no effect in preventing AD or dementia. Biologically it seems feasible that statins could prevent dementia due to their role in cholesterol reduction and initial evidence from observational studies was very promising. Indication bias may have been a factor in these studies however and the evidence from subsequent RCTs has been negative.

Meta AnalysisPrimary prevention of cardiovascular mortality and events with statin treatments: a network meta-analysis involving more than 65,000 patients.
This study aimed to evaluate the effectiveness of 3-hydroxy-3-methyl-glutaryl-CoA reductase inhibitors (statins) in primary prevention of cardiovascular events. ⋯ Statins have a clear role in primary prevention of CVD mortality and major events.

Review Meta AnalysisEzetimibe for the treatment of hypercholesterolaemia: a systematic review and economic evaluation.
To review the clinical and cost-effectiveness of ezetimibe as a combination therapy or monotherapy for the treatment of primary hypercholesterolaemia in the UK. ⋯ The short-term RCT clinical evidence demonstrated that ezetimibe was effective in reducing LDL-c when administered as monotherapy or in combination with a statin. However, when used as a monotherapy, ezetimibe is less effective than statins in lowering LDL-c. Given the limitations in the effectiveness data, there is great uncertainty in the economic results. These suggest that ezetimibe could be a cost-effective treatment for individuals with high baseline LDL-c values, for patients with diabetes and for individuals with heterozygous familial hypercholesterolaemia. Long-term clinical outcome studies are needed to allow more precise cost-effectiveness estimates to be calculated.
