Superficial skin exposures pose a higher rabies risk than previously thought

While it was previously thought that keratinocytes (skin cells) were only passive conductors that allow the rabies virus to pass through, novel research reveals that these cells play a much more active role. The findings of a new study in the Journal of Investigative Dermatology (JID), published by Elsevier, provide direct evidence that keratinocytes can support viral replication and transmit the rabies virus to neurons. The investigators offer a mechanistic explanation for how superficial skin exposures from scratches or minor bites by dogs and bats can lead to neuroinvasion, contributing to the risk of infection.

Waist-to-height ratio outperforms BMI in predicting hypertension risk

New waist-to-height cut-offs to assess fat mass and obesity predicted the risk of hypertension better than body mass index, according to a new study from the University of Eastern Finland and the Robert Wood Johnson Medical School at Rutgers University in the US.

Standard naloxone doses may not reverse newer synthetic opioid overdoses

A new study exposes challenges in reversing opioid overdoses with naloxone when potent synthetic drugs like fentanyl and sufentanil are involved, according to a study in the May 2026 issue of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA).

Mezagitamab shows promise in treating immune thrombocytopenia patients

Results from a phase 2 clinical trial designed and overseen by researchers at Mass General Brigham Cancer Institute show that the investigational medication mezagitamab can effectively boost platelet counts in patients with immune thrombocytopenia (ITP), an autoimmune disease characterized by elevated platelet destruction and reduced platelet production that increases bleeding risk and compromises quality of life.
