MONTREAL – April 24, 2026 – Findings from the North American COVID-19 Myocardial Infarction (NACMI) registry demonstrate significantly higher one-year mortality rates in patients with COVID-19 and ST-elevation myocardial infarction (STEMI) compared to patients with STEMI alone. This registry is the first study to describe long-term outcomes in patients with STEMI and COVID-19. Researchers presented the late-breaking data today at the Society for Cardiovascular Angiography & Interventions (SCAI) 2026 Scientific Sessions & Canadian Association of Interventional Cardiology/Association Canadienne de cardiologie d’intervention (CAIC-ACCI) Summit in Montreal.

Infection researchers at the German Primate Center – Leibniz Institute for Primate Research in Göttingen have found that the most recently dominant variants are not being replaced by a new variant that spreads rapidly worldwide. Instead, an unusual variant, BA.3.2, is spreading relatively slowly. This variant is not successful in all countries, but it frequently infects children. These observations suggest that a complex immunity may have developed through vaccination and infections, making it difficult for new variants to break through.

Kyoto, Japan -- The Covid-19 lockdowns were difficult for everyone. Many people were stuck at home all day every day dealing with their uncertainty for the future, and some found it hard to avoid frequent eating and snacking habits during lockdown. For many, the effects of this were marginal, but the risks in such a situation are higher for people with glucose intolerance, a group of metabolic conditions that includes diabetes.

Previous studies examining glycemic control in individuals with glucose intolerance during the Covid-19 pandemic have reported mixed results: some showed worsening control while others found no significant changes. In one specific study on individuals in Japan, a team of researchers at Kyoto University found that the state of emergency led to increases in body weight, fat mass, and snacking frequency, all of which were associated with deteriorating glycemic control.

However, the researchers recognized that the longterm metabolic effects of this after the full relaxation of behavioral restrictions has remained unclear. This gap in knowledge motivated the team to explore the post‑restriction period in greater depth.

A new study from University Hospitals Connor Whole Health found that pediatric patients with long-COVID report high symptom burden that meets or exceeds that of other chronic health conditions.

Nanyang Technological University, Singapore (NTU Singapore) is working with China’s Southern University of Science and Technology (SUSTech) and Swedish biotechnology company Lipigon Pharmaceuticals AB to develop a new inhaled treatment aimed at helping patients recover faster from severe lung infections. The treatment is designed to reduce excessive inflammation in the lungs, which can continue even after viruses or bacteria have been cleared from the body. To tackle this, the new therapy targets a protein called Angiopoietin-like protein 4 (ANGPTL4), which increases during inflammatory stress in the lungs. High levels of ANGPTL4 are associated with increased vascular permeability and fibrosis in injured lung tissue. Instead of being taken as a pill or injection, the treatment is delivered directly into the lungs by inhalation, similar to how asthma medications are administered. This allows it to act where it is needed most while limiting effects on the rest of the body.
