The coronavirus disease 2019 (COVID-19) pandemic has produced numerous safety concerns for sleep medicine patients and health-care workers, especially related to the use of aerosol-generating positive airway pressure devices. Differences between physician and sleep technologist concerns with regard to viral exposure and mitigation strategies may inform protocols to ensure safety and promote patient and health-care worker resilience and retention. ⋯ Sleep health-care workers reported high levels of concern about exposure to COVID-19. Physicians and technologists generally showed high concordance with regard to the need for mitigation strategies, but the respondents differed widely with regard to which strategies were necessary.

Pulmonary contusions (PCs) have historically been viewed as a serious complicating factor in thoracic injury. Recently, there has been conflicting evidence regarding the influence of PCs on outcomes; however, many studies do not stratify contusions by severity and may miss clinical associations. We sought to identify if contusion severity is associated with worse outcomes. ⋯ In severely injured polytrauma patients, PCs are seen with more severe chest injuries. Furthermore, moderate to severe contusions are associated with longer durations of mechanical ventilation, ICU length of stay, and hospital length of stay. Despite practice pattern changes, contusions appear to contribute significantly to the clinical course of the blunt chest wall injured patients.

The novel coronavirus-associated ARDS (COVID-19 ARDS) often requires invasive mechanical ventilation. A spectrum of atypical ARDS with different phenotypes (high vs low static compliance) has been hypothesized in COVID-19. ⋯ In our cohort of mechanically ventilated COVID-19 ARDS subjects, high PEEP and D-dimer were associated with increase in physiologic dead space without significant effect on oxygenation, raising the question of potential microvascular dysfunction.

Results of recent studies suggest that the incidence and mortality of ARDS may be higher than previously thought in pediatric trauma patients. We conducted a systematic review of the literature on incidence, risk factors, prognostic factors, and outcomes of ARDS after pediatric trauma in the ICU. ⋯ The ARDS incidence of 4.2% in the subjects with pediatric trauma in the ICU was comparable with 3.2% in the general pediatric ICU population; however, mortality associated with trauma-associated ARDS was higher and more commonly due to multi-system organ failure rather than hypoxemia.

Asthma is a prevalent disease that disproportionately affects socioeconomically underprivileged minorities. In fact, racial and ethnic minorities such as Blacks and Latinos have higher rates of severe asthma, asthma-associated emergency department visits, hospitalizations, and readmissions compared with whites. Such disparities exist due to genetic predispositions and to socioeconomic determinants of health such as environmental factors and limited health-care access. ⋯ Efforts have been made to address asthma-related complications in these populations, which have been addressed at various levels of the care system, including the patient and family, community, organization, provider/microsystem, and policy. Many of these programs promote patient education and health-care accessibility through interdisciplinary and multi-dimensional approaches, and have been shown to be effective in reducing asthma-associated readmissions and hospitalizations, but these localized approaches have not been largely adopted. The wide-spread implementation of asthma programs is necessary to address factors related to the increased incidence of asthma and associated rates of hospitalizations and readmissions in impoverished, minority populations.
