Although maintaining some amount of positive end-expiratory pressure (PEEP) seems essential, selecting and titrating a specific level for patients with ARDS remains challenging despite extensive research on the subject. Although an "open lung" approach to ventilation is popular and has some degree of biological plausibility, it is not without risk. ⋯ Here we present a pragmatic approach based on simple measurements available on all ventilators, focused on achieving balance between the potential risks and benefits of PEEP. Acknowledging "best PEEP" as an impossible goal, we aim for a straightforward method to achieve "better PEEP."

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.

Smoking at the time of surgical treatment for lung cancer increases the risk for perioperative morbidity and mortality. The prevalence of persistent smoking in the postoperative period and its association with long-term oncologic outcomes are poorly described. ⋯ Persistent smoking after surgery for stage I NSCLC is common and is associated with inferior overall survival. Providers should continue to assess smoking habits in the postoperative period given its disproportionate impact on long-term outcomes after potentially curative treatment for early-stage lung cancer.

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.

Case Reports
A 26-Year-Old Woman With Retinal Telangiectasias, Onychodystrophy, and Persistent Dyspnea.
A 26-year-old woman with no significant past medical history sought treatment for worsening dyspnea and hypoxia. The exertional dyspnea began 2 years prior and was associated with substernal chest discomfort. She did not report myalgia, edema, or worsening of dyspnea on supine or upright position. ⋯ She also was discovered incidentally to be leukopenic and thrombocytopenic, with subsequent bone marrow biopsy revealing hypocellularity of 30% to 40%. The patient concurrently demonstrated bilateral visual impairment secondary to retinal telangiectasias with increased severity of deficit in the right eye. She subsequently was referred to our institution for further evaluation.
