Food processing is a fundamental requirement for extending the shelf life of food products, but it often involves heat treatment, which can compromise organoleptic quality while improving food safety. Infrared (IR) radiation has emerged as a transformative technology in food processing, offering a rapid, energy-efficient method for inactivating microbial cells and spores while preserving the nutritional and sensory attributes of food. Unlike traditional heating methods, IR technology enhances heating homogeneity, shortens processing time, and reduces energy consumption, making it an environmentally friendly alternative.

Background: Perianal fistulizing Crohn's disease (PFCD) is a challenging and debilitating phenotype of Crohn's disease that can negatively affect quality of life. Studies have begun to uncover the physiologic mechanisms involved in wound repair as it relates to PFCD and how aberrations in these mechanisms may contribute to fistula persistence.

Aims: To review the physiologic and pathophysiologic mechanisms of wound repair in PFCD and how specific therapeutic strategies may impact their outcomes.

Article Synopsis
  • Large-scale studies are essential to investigate the gut microbiota's complex relationships with health and disease, and tissue preservation methods need evaluation for feasibility in such research.
  • Biopsies from 20 adults with inflammatory bowel disease were preserved using three methods: flash freezing, nucleic acid preservative reagents, and formalin fixation with paraffin embedding (FFPE), with microbiota analyzed using sequencing.
  • Results showed that while preservative reagents can serve as viable alternatives to flash freezing, FFPE samples exhibited distinct community structures, highlighting the potential utility of historical samples despite differences in microbial profiles.

Background And Aims: The co-existence of fatigue, pain and faecal incontinence in people with Inflammatory Bowel Disease (IBD) is unknown. We aimed to determine the presence of and relationship between these symptoms and patients' desire for intervention.

Methods: Adults with IBD in the UK, recruited from clinics, the national IBD-BioResource, a patient charity and social media sources, completed PROMIS validated patient-reported questionnaires to identify fatigue, pain and faecal incontinence, in addition to symptom severity and impact, disease activity, anxiety and depression questionnaires and questions about their desire for help with these symptoms.

Congenital disorders of glycosylation (CDG) comprise a class of inborn errors of metabolism resulting from pathogenic variants in genes coding for enzymes involved in the asparagine-linked glycosylation of proteins. Unexpectedly to date, no CDG has been described for , encoding the alpha-1,2-glucosyltransferase catalyzing the final step of lipid-linked oligosaccharide biosynthesis. Genome-wide association studies (GWAS) of human traits in the UK Biobank revealed significant SNP associations with short sleep duration, reduced napping frequency, later sleep timing and evening diurnal preference as well as cardiac traits at a genomic locus containing a pair of paralogous enzymes and .
