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.
