AbstractChanges in corneal curvature have been reported with low-concentration atropine eyedrops for myopia treatment and have been suggested to play a role in the refractive changes observed during atropine therapy. A case of keratoconus was identified from the Western Australia atropine for the treatment of myopia (WA-ATOM) cohort. We tested the null hypothesis that 0.01% atropine eyedrops produce no change in corneal parameters or ectasia risk compared to placebo. Children with progressive myopia (6–16 years; n = 153) were randomly assigned to receive 0.01% atropine eyedrops or a placebo (2:1 ratio) for 2 years, followed by a 1-year washout. Scheimpflug imaging was performed at baseline, 24-months, and 36-months. Changes in corneal parameters were compared between the treatment and placebo groups using linear mixed models.

Effect of nursing care program on healthy lifestyle behaviours and quality of life in women with endometriosis: a randomised controlled trial - Nature

We’re sharing this article early to provide faster access to peer-reviewed, accepted research. It is citable and carries a permanent DOI. This version is subject to further edits and will be replaced automatically by the final Version of Record. All legal disclaimers apply. AbstractThis study was conducted to determine the effect of Endometriosis Nursing Care Program (ENCP), developed in line with Health Promotion Model for women with endometriosis, on women's quality of life and healthy lifestyle behaviours. This prospective, single-centre, randomized controlled trial was conducted with 46 women diagnosed with endometriosis who applied to the Endometriosis Outpatient Clinic of a training research hospital. Women with an Endometriosis Health Profile Questionnaire-5 (EHP-5) score ≥ 22 indicating reduced quality of life were included. Participants were randomly assigned to an intervention group (n = 23) receiving Endometriosis Nursing Care Program (ENCP) or a control group (n = 23) receiving routine care. The ENCP consisted of two individual 60-min sessions delivered two weeks apart. The primary outcome was change in quality of life measured by EHP-5.

Antibody patterns may predict inflammatory bowel disease years before diagnosis - News-Medical

A large-scale study, presented today at UEG Week 2026, has identified distinct antibody patterns up to 10 years before the diagnosis of inflammatory bowel disease (IBD), potentially opening new avenues for earlier risk detection and providing insights into future disease course. IBD is a group of chronic conditions, including Crohn's disease (CD) and ulcerative colitis (UC), in which abnormal immune responses contribute to ongoing inflammation and damage in the digestive system. Although IBD is increasingly recognized to develop over a prolonged period before diagnosis, relatively little is known about the immune changes that occur during this time.

Antibiotic exposure during childhood linked to higher risk of IBS in young adults - News-Medical

Antibiotic use from childhood through early adulthood was associated with higher odds of irritable bowel syndrome (IBS) at age 24, with the odds increasing as the number of antibiotic prescriptions rose, according to a new study presented today at UEG Week 2026. IBS is a common digestive disorder that affects more than 60 million people across Europe, causing symptoms such as abdominal pain and changes in bowel habits. Whilst previous research has suggested a link between antibiotic use and IBS, evidence on whether childhood exposure is associated with IBS in adulthood remains inconsistent. Much of the existing evidence relies on people recalling past antibiotic use, with a lack of population-based studies using objectively recorded antibiotic data across childhood.

E. coli Vaccine Fails to Prevent Invasive Infections - EMJ

AN EXPERIMENTAL vaccine designed to prevent invasive Escherichia coli infections in older adults has failed to demonstrate clinical efficacy in a large Phase III trial, despite generating robust and sustained immune responses. The E.mbrace trial, involving 17,701 participants across 20 countries, found no demonstrated protective benefit from the nine-valent ExPEC9V vaccine compared with placebo. Following a prespecified futility analysis, the study was terminated early, and development of the vaccine has been discontinued.
