Review Meta AnalysisEffect of chewing gum on gastrointestinal function after gynecological surgery: A systematic literature review and meta-analysis.
Recently, several randomized controlled trials (RCT) reported the effect of chewing gum on gastrointestinal function after gynecological surgery; however, these results are inconsistent. The aim of this study was to systematically analyze the effect of chewing gum on postoperative gastrointestinal function and complications in women undergoing gynecological surgery. ⋯ Chewing gum is an effective measure to ameliorate gastrointestinal function and decrease complications after gynecological surgery.

Review Meta AnalysisVitamin D and risk of preterm birth: Up-to-date meta-analysis of randomized controlled trials and observational studies.
We performed a meta-analysis of randomized controlled trials (RCT) and observational studies to answer the two following questions: (i) whether low maternal circulating 25 hydroxyvitamin D (25-OHD) is associated with an increased risk of preterm birth (PTB) or spontaneous PTB (sPTB); and (ii) whether vitamin D supplementation alone during pregnancy can reduce the risk of PTB. ⋯ Maternal circulating 25-OHD deficiency could increase PTB risk and vitamin D supplementation alone during pregnancy could reduce PTB risk. Extrapolation of the results, however, must be done with caution, and there is urgent need for larger, better-designed RCT to confirm this effect.

Review Meta AnalysisEffects of epidural neostigmine and clonidine in labor analgesia: a systematic review and meta-analysis.
To evaluate the effect and quality of epidural neostigmine and clonidine added to initial spinal analgesia in labor analgesia. ⋯ Epidural administration of neostigmine and clonidine, following the spinal injection of local anesthetic, has a stronger analgesic effect in managing labor pain and reduces hourly anesthetic consumption. No obvious adverse reactions were found.

Review Meta Analysis Comparative StudyLetrozole versus clomiphene citrate for unexplained infertility: a systematic review and meta-analysis.
The objective of this study is to investigate and compare the effectiveness of letrozole and clomiphene citrate for improving fertility outcomes, including pregnancy rate, miscarriage rate, multiple pregnancy rate, and incidence rate of adverse events, number of dominant follicles, endometrial thickness at hCG day and serum E2 on hCG day. MEDLINE, EMBASE, CENTRAL, CNKI and CBMdisc databases were searched up to March 2013. Randomized controlled trials comparing letrozole with clomiphene in women with unexplained infertility were included. ⋯ The results of this study conclude that letrozole is as effective as clomiphene in women with unexplained infertility. Letrozole at a dose of 2.5 mg seems more effective. Further high-quality studies assessing the possible effectiveness of letrozole in selected groups of patients are warranted.

Meta Analysis Comparative StudyColloid or crystalloid solution on maternal and neonatal hemodynamics for cesarean section: a meta-analysis of randomized controlled trials.
To compare the effect of colloid and crystalloid on maternal and neonatal hemodynamics in cesarean section. ⋯ Colloid hydration should be considered first, especially in Asian patients, focusing on dosage and type of fluids. Preventive or therapeutic vasopressors may be required in a significant proportion of patients.
