Article Synopsis
- The study investigates differences in thrombo-inflammatory responses and outcomes between non-COVID-19 community-acquired pneumonia (CAP) and COVID-19 CAP in hospitalized adults in Canada.
- Non-COVID-19 CAP patients displayed lower 28-day mortality rates and fewer complications compared to those with COVID-19, indicating a more effective immune response developed over time against bacterial infections.
- The findings suggest that the complexities of the immune response to COVID-19 resulted in higher mortality rates, highlighting the challenges posed by emerging viruses compared to known pathogens.
Background: In 2019, SARS-CoV-2, the novel coronavirus, entered the world scene, presenting a global health crisis with a broad spectrum of clinical manifestations. Recognizing the significance of metabolomics as the omics closest to symptomatology, it has become a useful tool for predicting clinical outcomes. Several metabolomic studies have indicated variations in the metabolome corresponding to different disease severities, highlighting the potential of metabolomics to unravel crucial insights into the pathophysiology of SARS-CoV-2 infection.

This study aims to compare patients with community acquired pneumonia (CAP) treated in academic and community hospitals with respect to their demographics, clinical characteristics, treatments and outcomes.
Methods: This nested observational cohort substudy of the Community Acquired Pneumonia: Toward InnoVAtive Treatment (CAPTIVATE) trial included 1,329 hospitalized adults with CAP recruited between March 1st, 2018 and September 31st, 2023 from 15 Canadian hospitals.
Article Synopsis
- Researchers investigated the effect of losartan, an angiotensin receptor blocker, on 28-day mortality in hospitalized COVID-19 patients compared to usual care, due to its potential impact on angiotensin levels.
- The study was stopped early due to safety concerns, showing that adverse events and hypotension were significantly higher in the losartan group (39.8% SAEs and 30.4% hypotension) versus the control group (27.2% SAEs and 15.3% hypotension).
- There was no significant difference in 28-day mortality (6.5% for losartan vs. 5.9% for usual care), indicating that ARBs should be used cautiously in this patient population to
Freshwater fishes are among the most biodiverse vertebrate groups and among the most threatened by anthropogenic activities. Many occur in small and geographically restricted populations that are increasingly subject to catastrophic events (hurricanes, wildfires, extreme floods and droughts), but it has rarely been possible to assess the impacts of such events. Here we document the decline and recovery of a regularly monitored, small shoal bass (Micropterus cataractae) population in the Chipola River, Florida following a catastrophic hurricane disturbance.
