We report the utility of rapid antigen tests (RAgT) in a cohort of US healthcare personnel with coronavirus disease 2019 (COVID-19) infection who met symptom criteria to return to work at day 5 or later of isolation. In total, 11.9% of initial RAgT were negative.

Aerosol-generating procedures in the office represent a major concern for health care-associated infection of patients and health care providers by SARS-CoV-2, the causative agent for coronavirus disease 2019 (COVID-19). Although the Centers for Disease Control and Prevention has not yet provided any recommendations for the use of portable air purifiers, air purifiers with high-efficiency particulate air (HEPA) filters have been discussed as an adjunctive means for decontamination of SARS-CoV-2 aerosols in health care settings. This commentary discusses HEPA filter mechanisms of action, decontamination time based on efficiency and flow rate, theoretical application to SARS-CoV-2, and limitations.

- The study focused on Korean men with cardiovascular disease (CVD) to understand factors influencing their smoking behavior, highlighting that Korea has the world's highest smoking rates among men.
- Data was gathered through structured interviews and medical records from 97 hospitalized men, revealing that many were married, employed, and had a high school education or more, with 65% considered nicotine-dependent.
- Key predictors of smoking addiction included lower education, early smoking onset, and higher daily cigarette consumption, emphasizing the need for targeted smoking cessation interventions in this demographic to improve health outcomes.
Objectives: Our purpose was to evaluate the impact of nesiritide on renal function in patients with acute decompensated heart failure and baseline renal dysfunction.
Background: Although nesiritide is approved for the treatment of acute decompensated heart failure, retrospective analyses have raised concerns that it may cause worsened renal function. To date, no randomized clinical trials have prospectively evaluated this issue.
Background: A particularly high rate of smoking among South Korean men corresponds to high rates of cardiovascular disease.
Objectives: This study evaluated South Korean men hospitalized with cardiovascular disease to explore beliefs about the health benefits of smoking cessation, to determine smoking cessation intentions, and to identify factors associated with confidence in quitting smoking.
Methods: This was a cross-sectional, descriptive study.
