Multicenter Study
Prevalence and 24-month recovery of olfactory dysfunction in COVID-19 patients: A multicenter prospective study.
To investigate the prevalence and recovery of olfactory dysfunction (OD) in COVID-19 patients 24 months after the infection. ⋯ Two years post-COVID-19, 29.8% of patients reported persistent OD, but only 2.9% had abnormal identification psychophysical evaluations.

Clinical features and outcomes of SARSCoV-2 infections may change between different waves of the pandemic. The objective of this study was to compare clinical characteristics and outcomes between two cohorts of patients hospitalized for COVID-19 during the first and second waves in Argentina. ⋯ Compared to patients admitted during the first wave, patients admitted with SARS-CoV2 during the second wave in Argentina were more seriously ill and had a higher mortality.

Multicenter Study
The National Response to Patients with Acute Coronary Syndrome during the First Wave of the COVID-19 Pandemic in Portugal.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to changes in healthcare institutions and medical assistance. Non-SARS-CoV-2 related diseases were indirectly affected by the pandemic. Nonetheless, their treatment remains crucial. Cardiovascular conditions such as acute coronary syndrome (ACS) are common, and it was necessary to adjust medical assistance to these diseases during the pandemic. This study aimed to assess the national impact and healthcare system response during the first wave of the pandemic in patients admitted for ACS. ⋯ During the first wave of the SARS-CoV-2 pandemic there was a nationwide reduction in demand of healthcare services due to ACS events. Even though the Portuguese healthcare system was under strain and forced to divert resources and medical assistance towards the pandemic management, it was capable of responding adequately to ACS.

Knowledge about protection conferred by previous Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and/or vaccination against emerging viral variants allows clinicians, epidemiologists, and health authorities to predict and reduce the future Coronavirus Disease 2019 (COVID-19) burden. We investigated the risk and symptoms of SARS-CoV-2 (re)infection and vaccine breakthrough infection during the Delta and Omicron waves, depending on baseline immune status and subsequent vaccinations. ⋯ Our data suggest that hybrid immunity and booster vaccination are associated with a reduced risk and reduced symptom number of SARS-CoV-2 infection during Delta- and Omicron-dominant periods. For previously noninfected individuals, booster vaccination might reduce the risk of symptomatic Omicron infection, although this benefit seems to wane over time.

Randomized Controlled Trial Multicenter Study
Neutralizing COVID-19 Convalescent Plasma in Adults Hospitalized with COVID-19: A Blinded Randomized Placebo-Controlled Trial.
Convalescent plasma has been one of the most common treatments for COVID-19, but most clinical trial data to date have not supported its efficacy. ⋯ gov.
