A study comparing one- and three-month antibiotic treatments to prevent active tuberculosis (TB) finds that a high percentage of patients successfully completed both regimens and suffered few adverse side effects. A team led by Richard Chaisson, of the Johns Hopkins School of Medicine, U.S.A., reports these findings in PLOS Medicine. https://medicalxpress.com/news/2026-02-shorter-treatment-regimens-safe-options.html Tue, 10 Feb 2026 14:00:02 EST news689872753 A research team from POSTECH and ImmunoBiome in Korea, led by Professor Sin-Hyeog Im, has uncovered a new mechanism showing how butyrate—a short-chain fatty acid produced by gut commensal bacteria—enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy. This study identifies a new microbiota–immune–antibody production axis linking microbial metabolism to mucosal immune responses, providing a strategy to maximize the protective effects of mucosal vaccines. The findings are published in the journal Microbiome. https://medicalxpress.com/news/2026-02-gut-microbe-derived-butyrate-immune.html Thu, 05 Feb 2026 11:00:40 EST news689511601 Digestive disorders can affect us all from time to time. Symptoms such as bloating and pain, often accompanied with some change in bowel habits, can be a feature of dietary changes, infection and stress. However, when these symptoms last a long time and no clear cause is found, they can be hard to diagnose and treat. https://medicalxpress.com/news/2025-04-ibs-sibo-overlapping-symptoms-digestive.html Tue, 29 Apr 2025 13:05:04 EDT news665150701 Over-the-counter nasal sprays could be a potent weapon against a major public health threat—antibiotic resistance, researchers report. https://medicalxpress.com/news/2024-07-otc-nasal-sprays-ease-colds.html Mon, 15 Jul 2024 10:10:01 EDT news640254447 A randomized controlled trial in Hong Kong finds that the synbiotic drug SIM01 relieves multiple symptoms of long COVID, or post-acute COVID-19 syndrome (PACS). https://medicalxpress.com/news/2023-12-experimental-drug-gut-microbiome-covid.html Fri, 29 Dec 2023 10:07:42 EST news623066851 An outbreak of deadly tick-borne disease is occurring among people who've recently been to Baja California in Mexico, the U.S. Centers for Disease Control and Prevention warns. https://medicalxpress.com/news/2023-12-cdc-deadly-tick-borne-illness-people.html Mon, 11 Dec 2023 12:59:20 EST news621521956 Tuberculosis is often seen as a threat of the past.

This is important for two key reasons. Acne affects nearly everyone at some point in life—it is, in fact, the eighth most common disease for all humans, affecting more than 85% of adolescents and young adults. And second, because antibiotics have long been an important go-to treatment for acne, dermatologists write more antibiotic prescriptions than any other specialty in medicine. https://medicalxpress.com/news/2023-03-antibiotics-acne.html Wed, 08 Mar 2023 12:47:26 EST news597502042 In the fight against the COVID-19 pandemic, mRNA-based vaccines have impressively demonstrated their potential.
