The COVID-19 pandemic has strained health care systems and has resulted in widespread critical care staffing shortages, negatively impacting the quality of care delivered. ⋯ Restrictive visitation policies contributed to moral distress as reported by intensivists, highlighting the need to reconsider the risks and benefits of these policies. We also identified several interventions as perceived by intensivists that may help to mitigate moral distress and to improve burnout as part of efforts to preserve the critical care workforce.

SARS-CoV-2-related ARDS is associated with endothelial dysfunction and profound dysregulation of the thrombotic-fibrinolytic pathway. Defibrotide is a polyanionic compound with fibrinolytic, antithrombotic, and antiinflammatory properties. ⋯ The use of defibrotide for management of SARS-CoV-2-related ARDS proved safe and tolerable. No hemorrhagic or thrombotic complications were reported during therapy, with promising outcomes in a patient population with a historically high mortality rate.

Lymphangioleiomyomatosis (LAM) and pulmonary Langerhans cell histiocytosis (PLCH) are cystic lung diseases in which a neoplastic cell is thought to be responsible for disease pathogenesis. The neoplastic LAM cell has mutations in the TSC genes, TSC1 or TSC2, whereas the neoplastic PLCH cell may have mutations in several genes (eg, BRAF, NRAS, MAP2K1). These mutations are not specific for PLCH and have been described in multiple cancers. TSC1 or TSC2 mutations and loss of heterozygosity (LOH) have also been described in cancers. ⋯ The presence of TSC2 LOH in circulating cells is not specific for LAM. The data suggest that chromosomal abnormalities affecting the TSC2 gene are found in other diseases associated with cells having cancer-like neoplastic cells.

Observational Study
Swimming-induced pulmonary edema - evaluation of prehospital treatment with continuous positive airway pressure or positive expiratory pressure device.
Swimming-induced pulmonary edema (SIPE) occasionally occurs during swimming in cold open water. Although optimal treatment for SIPE is unknown, non-invasive positive pressure ventilation (NPPV) is an option for prehospital treatment. ⋯ NPPV administered as CPAP or via a PEP device proved feasible and safe as prehospital treatment for SIPE with a vast majority of patients discharged on site. Spo2 and patient-reported respiratory symptoms reflected recovery after treatment, whereas pulmonary auscultation or LUS findings did not.

Interstitial lung disease (ILD) results in profound symptom burden and carries high mortality. Palliative care (PC) is dedicated to improving quality of life in patients with serious illness. Early PC provision improves rates of advance care planning and symptom management in patients with ILD. ⋯ Most ILD providers use PC and are comfortable discussing PC. Barriers to PC identified in this survey include the following: perceived lack of local access to PC, lack of systematic tools to assess symptom burden, lack of established optimal timing of PC referral, and unclear need for specialized PC delivery.
