Diet and Microbiota Modulation for Chronic Pouchitis: Evidence, Challenges, and Opportunities.

Chronic pouchitis occurs in about 50% of patients undergoing a restorative proctocolectomy for ulcerative colitis. This affection represents a significant therapeutic challenge, particularly for symptomatic patients who do not respond to antibiotic treatments and biologic therapies. Several dietary approaches, including low FODMAP diets and the Mediterranean diet, have shown promising results in improving symptoms and disease burden.

Clinical, Radiological, and Surgical Risk Factors for Endoscopic Anastomotic Recurrence Following Surgery in Crohn's Disease.

This study investigated the radiological, clinical, and surgical factors linked to the risk of endoscopic recurrence following ileocolic resection for Crohn's disease. We conducted a retrospective analysis of data from all patients who underwent primary ileocecal resection for Crohn's disease in a single colorectal unit between 2004 and 2020. We analyzed the potential risk factors subdivided by the clinical, radiological, and surgical factors associated with morphological recurrence, as detected by endoscopy within 2 years after surgery.

Effectiveness of autologous emulsified stromal vascular fraction tissue injection for the treatment of complex perianal fistulas in inflammatory bowel diseases patients: a pilot study.

Complex fistulizing perianal disease is a disabling manifestation of inflammatory bowel disease (IBD), seriously compromising patients 'quality of life'. The success rate of available treatments is quite low, and nearly half of the patients will develop chronically active fistulas or experience fistula recurrence. Mesenchymal stem cell therapy has shown interesting results, but the complexity and the cost of production limit its widespread use.

Electrical impedance measurements can identify red blood cell-rich content in acute ischemic stroke clots associated with first-pass successful recanalization.

Background: Electrochemical impedance spectroscopy can determine characteristics such as cell density, size, and shape. The development of an electrical impedance-based medical device to estimate acute ischemic stroke (AIS) clot characteristics could improve stroke patient outcomes by informing clinical decision making.

Objectives: To assess how well electrical impedance combined with machine learning identified red blood cell (RBC)-rich composition of AIS clots , which is associated with a successfully modified first-pass effect.

Superradiant Thomson scattering from graphite in the extreme ultraviolet.

We study the Thomson scattering from highly oriented pyrolitic graphite excited by the extreme ultraviolet, coherent pulses of FERMI free electron laser (FEL). An apparent nonlinear behavior is observed and fully described in terms of the coherent nature of both exciting FEL beam and scattered radiation, producing an intensity-dependent enhancement of the Thomson scattering cross-section. The process resembles Dicke's superradiant phenomenon and is thus interpreted as the observation of superradiant Thomson scattering.
