Pharmaceutical manufacturers rarely reduce drug list prices, but 3 expensive treatments for hepatitis C experienced significant list price reductions in 2018. Understanding the impetus for these price reductions could inform policies to reduce drug spending. ⋯ List price reductions for hepatitis C treatments may have increased drug manufacturer net revenues, owing in part to lower discounts provided under the 340B program and the high share of sales subject to those discounts. Policymakers should consider the role of 340B discounts when evaluating policies to reduce drug spending.

A number of interventions are available to manage patients with moderate to severe acute respiratory distress syndrome (ARDS). However, the associations of currently available ventilatory strategies and adjunctive therapies with mortality are uncertain. ⋯ This network meta-analysis supports the use of prone positioning and venovenous extracorporeal membrane oxygenation in addition to lung protective ventilation in patients with ARDS. Moreover, venovenous extracorporeal membrane oxygenation may be considered as an early strategy for adults with severe ARDS receiving lung protective ventilation.

Research has shown an association between opioid prescribing after major or minor procedures and new persistent opioid use. However, the association of opioid prescribing with persistent use among women after vaginal delivery or cesarean delivery is less clear. ⋯ The results of the present study suggested that opioid prescribing and new persistent use after vaginal delivery or cesarean delivery have decreased since 2008. However, modifiable prescribing patterns were associated with persistent opioid use for patients who underwent vaginal delivery, and risk factors following cesarean delivery mirrored those of other surgical conditions. Judicious opioid prescribing and preoperative risk screening may be opportunities to decrease new persistent opioid use after childbirth.

The beneficial role of immunotherapy and the clinical relevance of current biomarkers in non-small cell lung cancer (NSCLC) remain inconclusive; thus, appropriate strategies and reliable predictors need further definition. ⋯ Immunotherapies showed promising clinical outcomes for patients with NSCLC. Pembrolizumab with platinum-based chemotherapy was found to be the most appropriate first-line immune checkpoint inhibitor regimen for advanced NSCLC, and the combined use of PD-L1 expression and TMB was found to be a promising biomarker to evaluate patients' survival and response to precision immunotherapy. The further combination of CD8+ T-cell tumor-infiltrating lymphocytes, PD-L1 expression, and TMB was associated with reliable prognosis. The predictive value of that combination needs to be prospectively validated in large-scale studies.
