Gut Microbes Activate T Cells Causing Autoimmune Eye Disease
NEW YORK (Reuters Health)—Commensal microbes in the gut can activate retina-specific T cells that go on to cause autoimmune uveitis in a mouse model, researchers report. “These findings allow us to understand the biological basis for the disease,” lead author of the study, Dr. Rachel Caspi from National Eye Institute at the NIH in Bethesda,…
Oral & Gut Microbiomes Altered in Rheumatoid Arthritis Patients
NEW YORK (Reuters Health)—Patients with rheumatoid arthritis (RA) have alterations in their oral and gut microbiomes that partially normalize with treatment, according to results from a metagenome-wide association study.

Patients Don’t Realize Smoking Worsens Inflammatory Bowel Disease
(Reuters Health)—Doctors know smoking can increase the risk for certain common inflammatory bowel diseases (IBD), but many patients haven’t gotten the message, a new study suggests. Out of 239 patients with two common types of IBD (Crohn’s disease and ulcerative colitis) only half were aware of the smoking risks associated with these conditions. “The take-home…
Nuclear Medicine Exposures Up Health Risks for Radiology Techs
NEW YORK (Reuters Health)—Technologists working in nuclear medicine have a heightened risk for some cancers and myocardial infarction, according to a nationwide U.S. survey led by National Cancer Institute (NCI) researchers. “Our results were mainly driven by exposures occurring before 1980, which is consistent with evidence that most cancers and other serious radiation-related chronic disease…
Similar RA Outcomes with Abatacept & Tocilizumab
NEW YORK (Reuters Health)—Clinical outcomes of rheumatoid arthritis (RA) are similar with abatacept and tocilizumab treatment, but the factors that predict efficacy differ for the two agents. “The recommendations for RA treatment from the U.S. and EU describe the use of abatacept and tocilizumab as first-line biologics along with anti-TNF (anti-tumor necrosis factor) inhibitors,” Dr….
