The latest meta-analysis indicated potential survival benefits from ultra-short-acting β-blockers in patients with sepsis with persistent tachycardia. However, subsequent multicenter randomized controlled trials (RCTs) have reported conflicting findings, prompting the need for an updated meta-analysis to incorporate these newly published RCTs. ⋯ In this updated meta-analysis, the use of esmolol or landiolol did not reduce mortality in patients with sepsis with persistent tachycardia. However, results were not robust and outcomes differed between single-center and multicenter RCTs. Moreover, sensitivity analyses showed the fragility of the primary outcome. Further studies regarding ultra-short-acting β-blockers with advanced cardiac monitoring or serial echocardiography are warranted.

Meta Analysis
Improving Cancer Probability Estimation in Non-Diagnostic Bronchoscopies: A meta-analysis.
In patients with peripheral pulmonary lesions (PPLs), nondiagnostic bronchoscopy results are not uncommon. The conventional approach to estimate the probability of cancer (pCA) after bronchoscopy relies on dichotomous test assumptions, using prevalence, sensitivity, and specificity to determine negative predictive value. However, bronchoscopy is a multidisease test, raising concerns about the accuracy of dichotomous methods. ⋯ Conventional dichotomous methods for estimating pCA after nondiagnostic bronchoscopies underestimate the likelihood of malignancy. Physicians should opt for the multidisease test approach when interpreting bronchoscopy results.

Review Meta Analysis Comparative Study
Comparison of early and late norepinephrine administration in patients with septic shock: a systematic review and meta-analysis.
Vasopressor administration at an appropriate time is crucial, but the optimal timing remains controversial. ⋯ Overall mortality did not differ significantly between early and late norepinephrine administration for septic shock. However, early norepinephrine administration seemed to reduce pulmonary edema incidence, and mortality improvement was observed in studies without fluid restriction interventions, favoring early norepinephrine use.

Reintubation is associated with higher risk of mortality. There is no clear evidence on the best spontaneous breathing trial (SBT) method to reduce the risk of reintubation. ⋯ In this study, HFO SBT was associated with a lower risk of reintubation compared with other SBT methods. The results of our analysis should be considered with caution due to the low number of studies that investigated HFO SBTs and potential clinical heterogeneity related to cointerventions. Further trials should be performed to confirm the results on larger cohorts of patients and to assess specific subgroups.

Refractory or unexplained chronic cough disrupts quality of life and burdens health care systems around the world. The P2X3 receptor antagonist gefapixant is approved in many countries for its antitussive effects, but taste disturbances are a common adverse effect. Four newer, more selective P2X3 receptor antagonists have been developed to address this problem. ⋯ University Hospital Medical Information Network Center (UMIN-CTR); No. UMIN000050622; URL: https://center6.umin.ac.jp.
