A research team at McMaster University has discovered a new drug class that could lead to breakthrough treatments for dangerous fungal infections. The discovery responds to a critical need for new antifungal medicines.
Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a rare autoimmune brain disease that mainly affects young people. Researchers from China reviewed a wide range of biomarkers that may help detect, understand, and treat this condition more effectively. These include antibodies, inflammatory markers, microRNAs, mitochondrial DNA, and neurofilament light chain proteins. Their findings highlight how biomarkers can guide diagnosis and treatment decisions, offering new insights into the disease’s underlying mechanisms and improving care for affected individuals.
The first paper from a multi-year clinical research study has been published in The Lancet Infectious Diseases: Dynamics of Endemic Virus Re-emergence in Children in the USA Following the COVID-19 Pandemic (2022-2023): A Longitudinal Immunoepidemiologic Surveillance Study and demonstrates how the approach can improve modeling to better predict future outbreaks.
The paper shares findings from a multicenter clinical research study, one of many studies that are part of the recently launched PREMISE (Pandemic Response Repository through Microbial and Immune Surveillance and Epidemiology) program, led by Dr. Daniel Douek at the National Institutes of Health’s (NIH) Vaccine Research Center (VRC). Data collected during the first year of the PREMISE study, 2022-2023, shows for the first time how non-pharmaceutical interventions such as masking and distancing targeted towards SARS-CoV-2 during the pandemic also decreased circulation rates of and population immunity to common respiratory pathogens in children. The study provides new evidence-based insight into what was driving the large post-pandemic rebound in these diseases and enables more accurate predictions for the future.
A new study meticulously sampled different lung regions in people with cystic fibrosis to understand why infections persist after treatment with new drugs called modulators. These drugs are not curative, but help improve symptoms by addressing the underlying physiological flaw in this genetic condition. Unexpectedly, the new findings suggest that lung damage might not be the main cause of infection persistence. It might be possible that the bacteria is adapting in new ways to resist clearance even when the lungs are being treated with the best drugs available.
