For children aged under 5, the incidence rate of SARS-CoV-2 infection is higher with the omicron versus the delta variant

For children aged under 5, the incidence rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was higher with the omicron variant versus the delta variant, according to a research letter published online April 1 in JAMA Pediatrics. Lindsey Wang, from the Case Western Reserve University School of Medicine in Cleveland, and colleagues examined incidence

SARS-CoV-2 innate defense system: the role of neutrophil and epithelial defensins

One of the most important layers of our body’s defense against SARS-CoV-2 lies in our innate immune system. The innate immune system protects our body from microbes, viruses, bacteria, and parasites that we have not previously encountered. While much of public attention and awareness of human immunity is focused on adaptive or learned immunity, innate

Most anti-PF4 antibodies in Covid-19 vaccine-induced immune thrombotic thrombocytopenia are transient

Platelet-activating anti-PF4 antibodies in VITT are transient in >90% of patients. Likely VITT patients can safely receive a second vaccination shot with an mRNA vaccine, independent of their VITT-antibody status. Vaccine-induced thrombotic thrombocytopenia (VITT) is triggered by vaccination against COVID-19 with adenovirus vector vaccines (ChAdOx1 nCoV-19; Ad26.COV2-S). In this observational study, were followed VITT patients

“Deltacron” a combination of the delta (AY.4) and BA.1 omicron variants named by the WHO as the BA.1 x AY.4 recombinant.

A combination of the delta (AY.4) and BA.1 omicron variants has been named by the World Health Organization as the BA.1 x AY.4 recombinant. First detected in France in January 2022, it has since picked up the nickname “deltacron”1 How does a recombinant emerge? Recombinants can emerge when multiple variants infect the same person at

American College of Cardiology Issues Clinical Guidance on CardioVascular Consequences of COVID-19

A new Expert Consensus Decision Pathway released by the ACC addresses the evaluation and management of some of the more common cardiovascular sequelae in adults with COVID-19. The Pathway, published March 16 in the Journal of the American College of Cardiology, specifically addresses myocarditis and other types of myocardial involvement, patient-centered approaches for long COVID, and

Excess Neuropeptides Disrupt Lung Function in Infant Disease and COVID-19

UC San Diego study identifies lung neuroendocrine cells as drivers of developmental lung disease; similar mechanism may contribute to COVID-19 symptoms COVID-19 has put a spotlight on the pulmonary and nervous systems, but there is still much to learn about how they interact. Researchers at University of California San Diego School of Medicine recently explored
