[Nosocomial outbreak of COVID-19 in an internal medicine ward: probable airborne transmission].
Despite the increasing evidence supporting the importance of airborne transmission in SARS-CoV-2 infection, it has not been considered relevant in the vast majority of reported nosocomial outbreaks of COVID-19. The aim of this study is to describe a nosocomial outbreak of SARS-CoV-2 infection whose features suggest that aerosol transmission had an important role. ⋯ The high attack rate, the explosive nature of the outbreak, and the coincidence in time with the breakdown in air extractors in some rooms of the ward suggest that airborne transmission played a key role in the development of the outbreak.

Many COVID-19 infected people remain asymptomatic, and hence the diagnosis at first presentation remains a challenge. Assessment at a presentation in primary care settings is usually done by visual triaging and basic clinical examination. This retrospective study involved investigating the medical e-records of COVID-19 positive patients who presented to a COVID-19 centre in Qatar for July 2020. ⋯ Compared to the asymptomatic group, the symptomatic group had lower Ct values (age groups [21-30], [31-40], [41-50] and [51-60]), higher temperature (age groups [21-30] and [31-40], Ct ranges [20.01-25.00] and [25.01-30.00]), higher HR (age groups [21-30] and [31-40], Ct range [15.01-20.00]); and lower SpO2 (age groups [41-50] and [51-60], Ct ranges [15.01-20.00] and [35.01-40.00]). Compared with asymptomatic patients, symptomatic patients with COVID-19 are most likely to be febrile, tachycardic, hypoxic and having higher viral load. Higher viral load was associated with higher HR, higher temperature, lower SpO2, but there was no relation between viral load and age.

This meta-analysis aimed to assess the usefulness of colchicine in patients with COVID-19. ⋯ Colchicine does not improve clinical outcomes in patients with COVID-19, so it did not support the additional use of colchicine in the treatment of patients with COVID-19.Key messageColchicine could not reduce the mortality of patients with COVID-19.No significant difference was observed between the colchicine and comparators in terms of the need for non-invasive ventilation, need for mechanical ventilation, and length of hospital stay.Colchicine was associated with a higher risk of gastrointestinal adverse events.

Examining Disparities and Excess Cardiovascular Mortality Before and During the COVID-19 Pandemic.
To investigate the patterns and demographic features of cardiovascular disease (CVD) death and subtypes myocardial infarction (MI), stroke, and heart failure in the pre-COVID-19 era (2018-2019) vs during the COVID-19 pandemic (2020-2021) in the United States. ⋯ There has been a significant rise in CVD and subtype-specific mortality during the COVID-19 pandemic that has been persistent despite 2 years since the onset of the pandemic. Excess CVD mortality has disproportionately affected Black compared with White individuals. Further studies targeting and eliminating health care disparities are necessary.
