Postoperative nausea and vomiting (PONV) is a common complication following surgery, and may be one of the most distressing parts of the surgical journey. With combination pharmacological therapy recommended for PONV prophylaxis, this systematic review and meta-analysis evaluates whether perioperative palonosetron and dexamethasone is more efficacious than palonosetron administered alone. ⋯ Combination prophylaxis with palonosetron and dexamethasone reduces post-operative anti-emetic requirement, although is not associated with a significant difference in PONV. There was considerable heterogeneity in the studies, and trial sequential analysis indicates that further studies are needed to strengthen the clinical evidence.

Meta Analysis Comparative Study
Efficacy and safety of baloxavir marboxil versus neuraminidase inhibitors in the treatment of influenza virus infection in high-risk and uncomplicated patients - a Bayesian network meta-analysis.
Previous network meta-analysis (NMA) demonstrated advantageous or similar efficacy of baloxavir marboxil (baloxavir) over neuraminidase inhibitors in otherwise healthy (OwH) influenza patients. This analysis assessed the efficacy and safety of baloxavir in the subgroup of high-risk (HR) patients and in the population of uncomplicated influenza consisting of OwH and HR patients with influenza. ⋯ Conclusions: Baloxavir was significantly more effective than placebo regarding all outcomes except for the risk of pneumonia. Besides, baloxavir was associated with similar clinical efficacy and safety, and superior antiviral activity compared to other antivirals in HR patients, as well as in the entire population of uncomplicated patients with influenza.

To assess the relative safety of oral tapentadol PR and other opioid analgesics for moderate or severe chronic pain in adults, we conducted a systematic review and network meta-analysis (NMA). ⋯ RCT evidence suggests that tapentadol can be a useful treatment option for patients suffering from chronic pain and in need of an opioid analgesic. Opioids should be prescribed by a qualified physician only after other analgesics have been considered, taking side effects and misuse risk into account.

Timely assessment of patient-specific prognosis is critical to oncology care involving a shared decision-making approach, but clinical prognostic factors traditionally used in NSCLC have limitations. We examine a proteomic test to address these limitations. ⋯ Advanced NSCLC patients classified VSGood have significantly longer OS than those classified VSPoor. The summary effect size for OS HRs around 0.4-0.5 indicates that the expected median survival of those with a VSGood classification is approximately 2-2.5 times as long as those with VSPoor. The robust prognostic performance of the VeriStrat test across various lines of therapy and treatment regimens has clinical implications for treatment shared decision-making and potential for novel treatment strategies.

Meta Analysis Comparative Study
The importance of considering differences in study and patient characteristics before undertaking indirect treatment comparisons: a case study of siponimod for secondary progressive multiple sclerosis.
Background: Indirect treatment comparisons (ITCs) provide valuable evidence on comparative efficacy where head-to-head clinical trials do not exist; however, differences in patient populations may introduce bias. Therefore, it is essential to assess between-trial heterogeneity to determine the suitability of synthesizing ITC results. We provide an illustrative case study in multiple sclerosis (MS) where we assess the feasibility of conducting ITCs between siponimod and interferon beta-1b (IFN β-1b) and between siponimod and ocrelizumab. ⋯ ITCs were not feasible between siponimod and ocrelizumab because study designs and patient populations were too dissimilar to conduct a reliable ITC. Conclusions: This study highlights the importance of conducting a detailed feasibility assessment before undertaking ITCs to illuminate when excessive between-trial heterogeneity would cause biased results. MAIC was performed for siponimod and IFN β-1b in the absence of a head-to-head trial and was considered a more valid approach than a traditional ITC to examine comparative effectiveness.
