Meta Analysis
Rash and Pruritus With PD-1 Inhibitors in Cancer Patients: A Meta-Analysis of Randomized Controlled Trials.
We performed a systematic review and meta-analysis to fully investigate the rash and pruritus of programmed death-1 (PD-1) inhibitors in cancer patients. The relevant studies of the randomized controlled trials in cancer patients treated with PD-1 inhibitors were retrieved, and a systematic evaluation was conducted. EMBASE, MEDLINE, and PubMed were searched for articles published up to April 2018. ⋯ But both all-grade rash and pruritus varied significantly according to control therapy. The current meta-analysis suggests that the use of PD-1 inhibitors significantly increases the risk of developing all-grade rash and pruritus. Physicians should be aware of these adverse events and should monitor cancer patients who are receiving PD-1 inhibitors.

Review Meta Analysis
Haloperidol Versus 5-HT3 Receptor Antagonists for Postoperative Vomiting and QTc Prolongation: A Noninferiority Meta-Analysis and Trial Sequential Analysis of Randomized Controlled Trials.
Haloperidol is an antipsychotic with well-known antiemetic potential. It is underutilized for postoperative nausea vomiting due to reported corrected QT interval (QTc) prolongation. This meta-analysis evaluates its safety and efficacy as an antiemetic in the perioperative period. ⋯ Publication bias was unlikely (Egger test, X-intercept = 2.07, P = 0.10). We conclude that haloperidol is equivalent to the well-established 5-HT3 -RAs in preventing vomiting during the first day after surgery. The incidence of QTc prolongation with haloperidol is statistically equivalent to 5-HT3 -RAs and thus should not be the factor that discourages its use for treatment/prophylaxis of postoperative nausea vomiting.

Review Meta Analysis
5-HT3 Receptor Antagonists for the Prevention of Perioperative Shivering: A Meta-Analysis.
The aim of this meta-analysis was to evaluate the preventive efficacy and safety of 5-HT3 receptor antagonists (5-HT3 RAs) on perioperative shivering. Relevant databases were searched to identify eligible randomized, controlled trials through January 2016. Primary outcome was the incidence of perioperative shivering, and secondary outcomes were the incidence of safety-related outcomes including postoperative nausea and vomiting (PONV), bradycardia, and hypotension. ⋯ However, they did not show superiority in lowering the rate of bradycardia (RR, 0.75; 95%CI, 0.38 to 1.49; P = 0.42; heterogeneity: I2 = 0%) or hypotension (RR, 0.79; 95%CI, 0.44 to 1.43; P = .44; heterogeneity: I2 = 24%). Trial sequential analysis of primary outcome showed that the required information size was 2634 patients and that the trial sequential monitoring boundary was crossed. Thus, more high-quality randomized, controlled trials with larger sample sizes are still required to draw a definite conclusion about the preventive efficacy of 5-HT3 RAs on perioperative shivering prevention in the future.

Meta Analysis Comparative Study
Comparison of dexmedetomidine and clonidine as adjuvants to local anesthetics for intrathecal anesthesia: A meta-analysis of randomized controlled trials.
The authors performed a meta-analysis to compare the characteristics of clonidine and dexmedetomidine as adjuvants to local anesthetic in intravertebral anesthesia. Four investigators independently searched electronic databases for randomized trials comparing the characteristics of clonidine vs dexmedetomidine as adjuvants to local anesthetic on adults. The endpoints were onset of analgesia, sensory and motor block, and duration of analgesia. ⋯ The duration of stable sensory block, duration of overall sensory block, and the time before the need for analgesic requirements were significantly extended, 10.8 minutes, 22.3 minutes, and 38.6 minutes, respectively, when dexmedetomidine was used as an adjuvant to local anesthetics (bupivacaine or ropivacaine). No significant differences were detected in the motor block characteristics and the time to achieve peak sensory level between dexmedetomidine and clonidine as adjuvants to local anesthetics. Compared to clonidine, the addition of dexmedetomidine as an adjuvant to local anesthetics is associated with earlier, prolonged sensory block characteristics and later need for analgesic requirements.

Meta Analysis
Bupivacaine in combination with fentanyl or sufentanil in epidural/intrathecal analgesia for labor: a meta-analysis.
This study is to compare the effectiveness of combinational use of bupivacaine with fentanyl (BUPI-FEN) and sufentanil (BUPI-SUF) in epidural/intrathecal analgesia for labor. Electronic databases were searched for relevant research papers published between 1985 and 2014. Meta-analyses of mean differences or odds ratios were performed and statistical heterogeneity between the studies tested by I(2) index. ⋯ The number of neonates with Apgar score < 7 was significantly lower in BUPI-FEN group (odd ratio [95%CI] of 0.31 [0.10, 0.95]; P < .05). Pruritus incidence was similar. In conclusion, BUPI-FEN combination exhibits significantly better tolerability at an approximate ratio of 6 FEN:1 SUF, albeit, both fentanyl and sufentanil in combination with bupivacaine provide similar analgesic properties via the epidural or intrathecal routes for labor pain relief.
