Randomized Controlled Trial
Dexmedetomidine for Reducing Mortality in Patients with Septic Shock: A Randomized Controlled Trial (DecatSepsis).
Sepsis, especially septic shock, and its complications have been linked to the hyperadrenergic stress response. ⋯ gov.

Breathlessness shares aging mechanisms with frailty and sarcopenia. ⋯ These findings suggest that frailty and sarcopenia strongly contribute to breathlessness in community-dwelling older adults. Measuring sarcopenia and frailty in older adults may offer opportunities to prevent age-related breathlessness.

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.

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.

Recommendations for Clinicians to Combat Environmental Disparities in Pediatric Asthma: A Review.
Asthma is a common and complex lung disease in children, with disproportionally higher prevalence and related adverse outcomes among children in racial and ethnic minority groups and of lower socioeconomic position. Environmental factors, including unhealthy housing and school-based exposures, can contribute to increased asthma morbidity and widening disparities. This underscores a significant environmental justice issue and suggests the need for clinical interventions to reduce sources of environmental exposures and ultimately diminish the observed disparities in childhood asthma. ⋯ Racial, ethnic, and socioeconomic disparities exist in asthma morbidity in children, and such disparities are driven in part by environmental factors at the housing and school level. Clinicians can make evidence-based recommendations to drive effective exposure reduction strategies to mitigate asthma morbidity and reduce observed disparities.
