Ileal Predominance in Crohn's Disease Is Associated With Increased Intestinal Surgery and Biological Therapy Use, With Lower Treatment Persistence.

Introduction: Crohn's disease (CD) varies by location, potentially affecting therapy efficacy and surgery risk, although research on this topic is conflicting. This study aims to investigate the independent association between CD location and therapeutic patterns.

Methods: We analyzed patients with CD diagnosed from January 2005 to May 2023 registered in the nationwide ENEIDA registry.

Oxidative Stress Induces Changes in Molecular Markers Associated with Ferroptosis in Human Spermatozoa.

Purpose: Ferroptosis is a type of iron-dependent regulated cell death characterized by increased bioavailability of redox-active iron, loss of GPX4 antioxidant capacity, and oxidation of polyunsaturated fatty acid-containing phospholipids mediated by reactive oxygen species (ROS). The aim of this study was to evaluate the effect of oxidative stress induced by arachidonic acid (AA) on ferroptotic cell death in human spermatozoa.

Materials And Methods: Spermatozoa from normozoospermic donors were exposed to AA (5, 25, and 50 µM) for 1 hour at 37 ℃, including an untreated control.

Influence of familial forms of inflammatory bowel disease on the use of immunosuppressants, biological agents, and surgery in the era of biological therapies. Results from the ENEIDA project.

Background And Aims: Familial inflammatory bowel disease (IBD) history is a controversial prognostic factor in IBD. We aimed to evaluate the impact of a familial history of IBD on the use of medical and surgical treatments in the biological era.

Methods: Patients included in the prospectively maintained ENEIDA database and diagnosed with IBD after 2005 were included.

Transmural cross-sectional findings and bowel damage assessment in preclinical Crohn's disease: a case-control study.

Purpose: Crohn's disease (CD) is a progressive disorder leading to cumulative bowel damage. The Lémann index is a validated tool that can help in monitoring the progression of the disease and evaluating the effectiveness of different therapies. Our aim was to describe the main radiological findings in incidentally diagnosed CD and to evaluate bowel damage in this subgroup compared to patients diagnosed at later stages.

Effect of exogenous sperm capacitation inducers on stallion sperm.

Although under appropriate laboratory conditions, sperm from different mammalian species can be capacitated in vitro, the optimal conditions for sperm capacitation in the stallion have been elusive. This study evaluated the effect of different capacitating inducers in Whitten and Tyrode media and assessed their impact on capacitation-related factors. Stallion sperm were incubated with different combinations of capacitating inducers at 38.
