AI Article Synopsis

  • The study investigates natural feed additives as alternatives to robenidine in improving gastrointestinal health in weaner rabbits, amid high mortality rates due to overgrowth.
  • Rabbits were divided into four groups: a control group receiving only robenidine, a sainfoin-supplemented group, and two groups supplemented with herbal and mineral additives.
  • While natural additives did not significantly affect weight gain or oocyst counts compared to the control group, higher oocyst shedding in the sainfoin and herbal groups suggests potential benefits that warrant further investigation.

Article Abstract

Gastrointestinal disorders due to sp. and overgrowth cause high mortality in weaner rabbits and the interest in alternatives to coccidiostats is high. This study aimed to investigate the superiority of natural feed additives towards robenidine preserving gastrointestinal health in the field. Rabbits were divided into four groups, Control Group (CG) exclusively supplemented with robenidine, Sainfoin Group (SG) was supplemented with a combination of robenidine and sainfoin, and two additional groups were respectively supplemented with Herb-All COCC-X (garlic; conessi tree) (HG: Herbal Group) and by a combination of Herb-All COCC-X and Klinofeed (clinoptilolite) (MG: Mineral Group). sp (98,40%) and overgrowth (73.60%) could be confirmed as the main causes for losses. High mortality rates (SG: 30.00% - MG: 47.50%), also in the groups receiving robenidine (SG: 30.00%; CG: 45.00%), reinforced the importance of alternatives in the field. The natural additives of groups SG, HG and MG did not have a significant influence on the weight gains and the oocyst counts in the jejunum/ileum and caecum of slaughter rabbits at the end of the trial, compared to group CG. Significantly higher oocyst shedding in SG (p = 1.4E-03) and HG (p = 1.4E-05) during the trial may be explained by a higher surviving rate of diseased rabbits in those groups, fostered by beneficial effects of the additives, which should be investigated further.

Radiation exposure in patients with inflammatory bowel disease.

J Crohns Colitis

January 2025

Translational Research in Gastrointestinal Disorders (TARGID), Department of Chronic Diseases and Metabolism, KU Leuven, Leuven, Belgium and Department of Gastroenterology and Hepatology, University Hospitals Leuven, Belgium.

Background And Aims: Radiological imaging is crucial for diagnosing and monitoring patients with inflammatory bowel diseases (IBD). With increasing awareness of radiation risks, imaging doses should be 'as low as reasonably achievable', with a risk level that one should try to stay underneath 75 mSv. However, real-world data on cumulative exposure are limited.

Gallbladder cancer (GBC) is a highly lethal and often overlooked malignancy increasingly affecting young adults. This study quantified the global proportion of GBC cases attributable to 10 key modifiable risk factors, employing Monte Carlo simulations and estimates from field-wide systematic review and meta-analysis. Approximately three-quarters of global GBC cases are attributable to key modifiable factors (74.

Background/aims: Active inflammatory bowel disease (IBD) increases the risk of pregnancy complications and contraceptive side effects, and contraceptive use may impact the clinical course of IBD. Although young people are at elevated risk for unintended pregnancy, those with IBD receive minimal disease-specific contraceptive guidance. We characterized perspectives and preferences on contraception and reproductive health counseling from young women with IBD.

Whipple's disease is a rare bacterial infection that is often present for years prior to diagnosis. Symptoms are nonspecific in the early stages of presentation and are primarily gastrointestinal in nature. The disease may progress with more systemic symptoms including arthralgia, fever, lymphadenopathy, cardiovascular disease, and central nervous system involvement.
