Patterns of antibodies in people’s blood could predict the onset of inflammatory bowel disease (IBD) a decade before diagnosis, according to research that raises hopes for catching the condition early. Crohn’s disease and ulcerative colitis, the two main forms of IBD, are typically treated only after symptoms appear, when the gut has already been damaged. But scientists found that the immune system sends warning signals up to a decade before diagnosis, paving the way for potentially earlier detection and even prevention. “For too long we have only been able to treat inflammatory bowel disease once the damage is done, and for many people that is too late,” said Dr Arno Bourgonje at the University Medical Centre Groningen in the Netherlands and the Icahn School of Medicine at Mount Sinai in New York. “What we have shown is that the disease begins years before symptoms appear, and the immune system leaves warning signs long before diagnosis,” Bourgonje added.

How psychological stress can trigger arthritis flares via an inflammatory pathway - Medical Xpress
Psychological stress has long been associated with worsening symptoms in rheumatoid arthritis (RA). However, the underlying mechanism connecting psychological stress to the occurrence of joint inflammation has remained poorly understood. In particular, how psychological stress can trigger inflammation in joints that were previously affected, even after the disease has gone into remission, remains an important unanswered question.
Evaluating Adherence to iRefer Guidelines and Barriers to Implementation Among Non-consultant Hospital Doctors in a Model 3 Hospital: A Mixed-Methods Study - Cureus
Background The Royal College of Radiologists' (RCR) iRefer guidelines are an established evidence-based clinical decision support tool intended to optimise diagnostic imaging referrals, reduce unnecessary radiation exposure, and improve radiology workflow efficiency. In Ireland, imaging referrals also carry statutory weight: Statutory Instrument (S.I.) No. 256 of 2018 places defined duties on referrers regarding the justification of medical exposures, and Health Service Executive (HSE) guidance requires referrers to have access to iRefer or an equivalent decision support tool. Awareness and use of iRefer among non-consultant hospital doctors (NCHDs) in smaller, high-turnover hospital settings are poorly described. Aim To evaluate awareness, utilisation, and accessibility of the iRefer guidelines among NCHDs in a Model 3 hospital and to identify the systemic, technological, and cultural barriers preventing routine use. Methods A sequential explanatory mixed-methods design was employed. Phase 1 comprised an in-person, anonymous cross-sectional audit questionnaire developed by the authors for this study, administered to NCHDs to assess awareness, decision-making sources, and guideline
Bangladesh battles massive outbreaks of dengue and measles - Outbreak News Today
Dengue feverAccording to the Directorate General of Health Services (DGHS) in Dhaka, at least six dengue patients died and 2,088 others were hospitalised in the past 24 hours, bringing the total cases and deaths to 112,400 and 348, respectively. September has been the deadliest month of the year so far, logging 43,774 hospital admissions and 148 deaths. Significant outbreaks are hitting the Dhaka area and the Chattogram, Khulna, and Barishal divisions due to high population density and inadequate waste management. Typically a monsoon-season illness (June to September), dengue transmission in Bangladesh is increasingly shifting and extending into late autumn due to unseasonal rains and climate shifts. Currently, 6,026 dengue patients are undergoing treatment at hospitals across the country.

Sonce mid-March, the country reported 203,000 suspected measles cases, including 23,000 confirmed cases have been reported. At least 1,196 people have died, with children under five accounting for 94% of reported deaths.
New research shows how microplastics and water interactions could lead to cell damage - The Spokesman-Review
LOS ANGELES — Scientists have found microplastics in virtually every part of the human body. Yet many questions remain about what exactly these infinitesimal flecks of synthetic polymers do to human health, and how they might cause disease. A new paper looking at the chemical reactions between water and disintegrating plastic offers a potential hypothesis for how microplastics might make us sick.
