Meta AnalysisOpioid-Sparing Anesthesia Versus Opioid-Free Anesthesia for the Prevention of Postoperative Nausea and Vomiting after Laparoscopic Bariatric Surgery: A Systematic Review and Network Meta-Analysis.
Patients who undergo laparoscopic bariatric surgery (LBS) are susceptible to postoperative nausea and vomiting (PONV). Opioid-free anesthesia (OFA) or opioid-sparing anesthesia (OSA) protocols have been proposed as solutions; however, differences between the 2 alternative opioid protocols for anesthesia maintenance in obese patients remain uncertain. A network meta-analysis was conducted to compare the impacts of OFA and OSA on PONV. ⋯ OFA is more effective than OSA in reducing the occurrence of PONV during the early postoperative period of LBS, although it may associate with an increased risk of bradycardia. Patients who received either opioid-alternative strategy demonstrated similar effects in reducing postoperative opioid consumption and alleviating pain intensity.

Objective : To evaluate if mechanical left ventricular unloading could reduce mortality in patients with cardiogenic shock undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO). Methods : We searched MEDLINE, Embase, and the Cochrane Library for randomized controlled trials and propensity score-matched studies published until December 20, 2023. The primary outcome was mortality at the longest follow-up. ⋯ Mechanical left ventricular unloading was significantly associated with reduced mortality at the longest follow-up (RR, 0.89; 95% CI, 0.84-0.94; P = 0.0001; moderate certainty of evidence), which was confirmed in studies using intra-aortic balloon pump. Benefits of mechanical unloading were also observed in terms of successful VA-ECMO weaning (RR, 1.15; 95% CI, 1.02-1.29; P = 0.02; low certainty of evidence) and favorable neurological outcome (two studies; RR, 2.45; 95% CI, 1.62-3.69; P < 0.0001; low certainty of evidence), although we observed an increased incidence of major bleeding (RR, 1.27; 95% CI, 1.02-1.59; P = 0.03; low certainty of evidence) and hemolysis (RR, 1.49; 95% CI, 1.10-2.02; P = 0.01; moderate certainty of evidence). Conclusions : Among adult patients with cardiogenic shock treated with VA-ECMO, mechanical left ventricular unloading was associated with reduced mortality, which was confirmed in studies using intra-aortic balloon pump as an unloading device.

Delay in the Diagnosis of Pediatric Brain Tumors in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis.
Vague symptoms and a lack of pathognomonic features hinder the timely diagnosis of pediatric brain tumors (PBTs). However, patients in low- and middle-income countries (LMICs) must also bear the brunt of a multitude of additional factors contributing to diagnostic delays and subsequently affecting survival. Therefore, this study aims to assess these factors and quantify the durations associated with diagnostic delays for PBTs in LMICs. ⋯ A multitude of factors contribute to diagnostic delays in LMICs. The disproportionate effect of these factors is demonstrated by the long interval between symptom onset and the definitive diagnosis of PBTs in LMICs, when compared with high-income countries. While evidence-based policy recommendations may improve the pace of diagnosis, policy makers will need to be cognizant of the unique challenges patients and health care systems face in LMICs.

Do Obese Patients Have Worse Outcomes in Adult Spinal Deformity Surgeries? A Meta-Analysis.
A meta-analysis study. ⋯ Nonobese patients undergoing ASD corrective surgery are associated with fewer implant-related complications, a lower EBL, shorter LOS, and a higher likelihood of being discharged home compared with their obese counterparts.

Inhaled Reliever Therapies for Asthma: A Systematic Review and Meta-Analysis.
The optimal inhaled reliever therapy for asthma remains unclear. ⋯ In this network meta-analysis of patients with asthma, ICS combined with formoterol and ICS combined with SABA were each associated with reduced asthma exacerbations and improved asthma control compared with SABA alone.
