Echocardiographic tricuspid annular plane systolic excursion (TAPSE) to systolic pulmonary arterial pressure (sPAP) ratio is a noninvasive surrogate for right ventricle (RV)-pulmonary arterial (PA) coupling. It has been related to outcome in patients with moderate to severe pulmonary hypertension (PH). ⋯ Our results indicate that in patients with suspected PH, but normal or only mildly elevated resting mPAP, TAPSE to sPAP ratio is an independent predictor of outcome. In addition, it is associated significantly with exercise capacity and exercise hemodynamics and may be a helpful tool in the prediction of future clinical worsening of this patient population.

Red Blood Cell Transfusion in Critically Ill Adults An American College of Chest Physicians Clinical Practice Guideline.
Blood products frequently are administered to critically ill patients. Considering recent trials and practice variability, a comprehensive review of current evidence was deemed essential to offer pertinent guidance to critical care practitioners. This American College of Chest Physicians (CHEST) guidelines panel examined the literature on RBC transfusions among critically ill patients overall and specific subgroups, including patients with gastrointestinal bleeding, acute coronary syndrome (ACS), cardiac surgery, isolated troponin elevation, and septic shock, to provide evidence-based recommendations. ⋯ In most critically ill patients, a restrictive strategy was preferable to a permissive approach because it does not increase the risk of death or complications, but does decrease RBC use significantly. Data from critically ill subpopulations also supported a restrictive approach, except in patients with ACS, for whom favoring a restrictive approach could increase adverse outcomes.

Sarcoidosis is a multisystem inflammatory disease in which management and outcomes can vary widely. The renin-angiotensin-aldosterone system (RAAS) has been implicated in its pathogenesis, yet the impact of RAAS modulators on health outcomes in sarcoidosis remains poorly understood. ⋯ Our findings suggest that ACEIs and ARBs have divergent effects on outcomes in patients with sarcoidosis. These findings highlight the potential pathogenic role of RAAS signaling in this disease and underscore the importance of carefully selecting RAAS modulators for individuals with sarcoidosis.

In the Handling Oxygenation Targets in COVID-19 (HOT-COVID) trial, a Pao2 target of 60 mm Hg compared with 90 mm Hg resulted in more days alive without life support at 90 days in adults in the ICU with COVID-19 and hypoxemia. The trial was stopped after enrolling 726 of 780 planned patients because of slow recruitment. Herein, we present the preplanned Bayesian analysis of the HOT-COVID trial. ⋯ gov.

Osteogenesis imperfecta (OI) is a rare hereditary disease mainly resulting in reduced or altered collagen type I. Collagen type I is a major constituent of the respiratory system, and normal collagen type I is vital for pulmonary tissue function. ⋯ Overall, the admission rates for respiratory diseases were low in the OI cohort, but a higher relative risk of hospitalizations resulting from respiratory disease compared with the general population. Timely diagnosis and treatment of respiratory complications in individuals with OI is warranted.
