Introduction Infections due to COVID-19 can lead to life threatening pneumonia. Accompanying severe disease are more prominent pulmonary changes on Computed Tomography (CT) scan of the chest. The goal of this study was to describe pulmonary CT changes during acute COVID-19 and at follow up and whether the extent of changes correlate with severity of illness, demographics or other risk factors. ⋯ Full recovery was seen at follow-up CT in 31% of patients (median 68,5 days between acute and follow-up imaging). Conclusion Patients with severe COVID-19 have more pronounced lung involvement on CT than patients with milder disease during the acute phase and follow-up. Older patients and males are at greater risk of acute and persistent COVID-19 related lung changes.

COVID-19 is regularly compared to influenza. Mortality and case-fatality rates vary widely depending on incidence of COVID-19 and the testing policy in affected countries. To date, data comparing hospitalized patients with COVID-19 and influenza is scarce. ⋯ In hospitalized patients, COVID-19 is associated with longer LOS, a higher number of complications and higher in-hospital mortality compared to influenza, even in a population with fewer co-morbidities. This data, a high reproduction number and limited treatment options, alongside excess mortality during the SARS-CoV-2 pandemic, support the containment strategies implemented by most authorities.

Efficacy and safety of hydroxychloroquine as pre-and post-exposure prophylaxis and treatment of COVID-19: A systematic review and meta-analysis of blinded, placebo-controlled, randomized clinical trials.
Hydroxychloroquine (HCQ) is an anti-malarial and immunomodulatory drug considered a potential candidate for drug repurposing in COVID-19 due to their in vitro antiviral activity against SARS-CoV-2. Despite the potential antiviral effects and anti-inflammatory profile, the results based on clinical studies are contradictory. Therefore, the quality of the decision-making process from meta-analyses summarizing the available evidence selecting studies with different designs and unblinded trials is limited. The aim of this study was to synthesize the best evidence on the efficacy and safety of HCQ as pre-and post-exposure prophylaxis and treatment of non-hospitalized and hospitalized patients with COVID-19. ⋯ There was no funding source.
