Multicenter Study
Estimates of Sepsis Prevalence and Outcomes in Adult Patients in the ICU in India: A Cross-sectional Study.
Sepsis is a global health problem. Limited data exist on the prevalence of sepsis using current definitions in ICUs in India. ⋯ This multicenter point prevalence study in Indian ICUs showed a high burden of sepsis using both Sepsis-2 and Sepsis-3 criteria, with associated high rates of antimicrobial resistance and mortality. These findings have implications for public health and future research.

A cardiopulmonary exercise test (CPET) is ideally suited to quantify exercise tolerance and evaluate the pathophysiological mechanism(s) of dyspnea and exercise limitation in people with chronic respiratory disease. Although there are several statements on CPET and many outstanding resources detailing the cardiorespiratory and perceptual responses to exercise, limited information is available to support the health care provider in conducting a practical CPET evaluation. ⋯ Information on CPET protocol, as well as how to evaluate maximal patient effort, peak rate of oxygen consumption, ventilatory demand, pulmonary gas exchange, ventilatory reserve, operating lung volumes, and exertional dyspnea, is presented. Two case examples are also described to highlight how these parameters are evaluated to provide a clinical interpretation of CPET data.

Lung cancer screening is slowly but steadily entering the realm of preventive health maintenance. Standardization of reporting of positive findings identified on screening low-dose CT (LDCT) scans, specifically lung nodules, is a key element of high-quality lung cancer screening. The American College of Radiology developed the Lung CT Screening Reporting and Data System (Lung-RADS) system for this purpose. ⋯ In contrast to the highly structured reporting for nodules, category S findings are reported at the discretion of individual readers, with the potential for high variability of reporting. Incidental findings on lung cancer screening studies are common, may trigger unwarranted evaluation with potential harm and cost, and may precipitate patient distress. In response to these concerns, our multidisciplinary lung cancer screening program developed a structured system for standardized reporting of category S findings based on recommendations of the American College of Radiology and relevant specialty societies.

The characteristics and outcomes of adult patients with respiratory syncytial virus (RSV) infection who require ICU admission are poorly defined. Although several studies in adults with RSV infection have been published in recent years, they did not focus specifically on patients with critical illness. ⋯ Adult patients in the ICU with RSV infection differ from adult patients in the ICU with influenza in terms of comorbidities and characteristics at diagnosis. RSV infection was associated with high in-hospital mortality, approaching 25%. In multivariate analysis, RSV infection was associated with a similar odds of in-hospital death compared with influenza infection.

Brazil has been disproportionately affected by COVID-19, placing a high burden on ICUs. ⋯ During the COVID-19 pandemic, ICU HCPs in Brazil experienced substantial resource shortages, health care disparities between regions, changes in end-of-life care associated with resource shortages, and high proportions of burnout.
