Review Meta Analysis
Prognostic role of copeptin after stroke: A systematic review and meta-analysis of observational studies.
Copeptin, the C-terminal part of provasopressin, has emerged as a novel prognostic marker after hemorrhagic or ischemic stroke. The aim of this study was to quantitatively assess the prognostic significance of plasma copeptin level on functional outcome and mortality in patients with acute stroke using a meta-analysis of the available evidence. Thirteen relevant studies from 2,746 patients were finally included in our study. ⋯ A stratified analysis by study region showed significant differences in SMD of copeptin, and the heterogeneity among studies was significantly decreased. However, the positive association of copeptin with poor prognosis after stroke was consistent in each stratified analysis. The present meta-analysis suggests that early measurement of plasma copeptin could provide better prognostic information about functional outcome and mortality in patients with acute stroke.

Meta Analysis
A comparision of nalbuphine with morphine for analgesic effects and safety : meta-analysis of randomized controlled trials.
Although morphine is the standard opioid analgesic for pain control and has been widely used, certain drug-induced adverse effects have been reported as intolerable and need to be addressed. Nalbuphine may have a few advantages over morphine in this respect. We aimed to describe the effect of nalbuphine as well as its safety compared to morphine by analyzing published randomized controlled trials (RCTs) with meta-analysis approach. ⋯ Overall, there was no evidence to show that the effect of pain relief had any difference between nalbuphine and morphine (pooled relative risks [RRs], 1.01; 95% CI, 0.91 to 1.11; P = 0.90). On the other hand, the incidences of pruritus, nausea, vomiting, respiratory depression were significantly lower in nalbuphine group compared with morphine group, and the pooled RRs were 0.78(95%CI, 0.602-0.997; P = 0.048) for nausea, 0.65(95%CI, 0.50-0.85; P = 0.001) for vomiting, 0.17(95%CI, 0.09-0.34; P < 0.0001) for pruritus, and 0.27(95%CI, 0.12-0.57; P = 0.0007) for respiratory depression. The analgesic efficacy of nalbuphine is comparable to morphine, but nalbuphine provides a better safety profile than morphine in the aspect of certain side-effects, especially related to pruritus and respiratory depression.
