Observational Study
Early treatment with low-molecular-weight heparin reduces mortality rate in SARS-CoV-2 patients.
Since the beginning of the SARS-CoV-2 pandemic, millions of people have been infected and died. Different therapeutic approaches have been recommended, but only a few have shown clinical advantages. Low-molecular-weight heparin (LMWH) has been recommended to prevent COVID-19-related thrombo-embolic events. We aimed to evaluate the impact of early treatment with LMWH on hospital admission and death in patients with SARS-CoV-2 infection. ⋯ Early treatment with LMWH was associated with lower mortality in our cohort. Further studies are needed to better assess the role of wider LMWH administration in terms of timing and regimen dose.

Cell and cytokine analyses from bronchoalveolar lavage (BAL) in non-critically ill patients with COVID-19 pneumonia are poorly described. This study focused on patients hospitalized in the non-intensive care unit for either suspected COVID-19 pneumonia or persistent respiratory symptoms following proven COVID-19 pneumonia. Overall, 54 patients who underwent BAL between April 2020 and February 2021 for suspected or follow-up of proven COVID-19 pneumonia were included. ⋯ In COVID-19 patients, correlations between IL-10, TNF-α and IFN-γ concentrations were found. Lymphocytic alveolitis with plasmacytosis was found in non-critical COVID-19 pneumonia This alveolitis is associated with the presence of IL-6, IL-8, IL-10, TNF-α, IFN-γ and HGF. Alveolitis and cytokines levels decreased in post-COVID-19 pneumonia.

In June 2023, the UK began official hearings for its independent investigation into pandemic preparedness. Thus far, the inquiry has been told that planning has been wholly inadequate and that a future outbreak is inevitable. We present here four key problems that contributed to significant morbidity and mortality during the Coronavirus 2019 (COVID-19) pandemic over the past 3 years in the UK - and which will contribute to excess morbidity and mortality in the next outbreak. ⋯ This meant that, as evidence evolved and different conclusions were drawn, the public lost faith in both the UK Government and science. Third, public health guidance did not take into account that certain groups would be impacted differentially by public health guidelines and instead used a one-size-fits-all approach to non-pharmaceutical interventions. Finally, there was worsening of existing inequalities, especially in ethnic minority groups, that resulted in excessive numbers within certain cohorts becoming infected.

Acute COVID-19 in unvaccinated children without a history of previous infection during the delta and omicron periods.
The Omicron variant has been the predominant severe acute respiratory syndrome coronavirus 2 variant circulating in Korea since January 2022. This study evaluated and compared the clinical characteristics of children with coronavirus disease 2019 (COVID-19) between the Delta and Omicron periods. ⋯ The incidence of fever and seizures was higher during the Omicron period in pediatric patients without a history of vaccination or previous COVID-19. However, the clinical severity was similar during both periods.

Neutralising antibodies against SARS-CoV-2 give important information on Covid-19 epidemic evolution in Rabat, Morocco, March 2020-February 2021.
The SARS-CoV-2 is an extremely contagious and acute viral disease mainly affecting humans. ⋯ And increase of NAbs was observed over time and correlated with the post-epidemic waves of COVID-19 in Morocco.
