The production of autoantibodies against the enzyme transglutaminase 2 (TG2) in celiac disease likely results from TG2-specific B cells receiving help from gluten-specific CD4+ T cells in gut-associated lymphoid tissues (GALT) via the formation of transient enzyme-substrate complexes formed between TG2 and gluten. Where in the body enzymatically active TG2 encounters gluten peptides remains unknown.

The hepatic steatosis index (HSI) is a validated tool for assessing hepatic steatosis. While previous investigations have explored the link between HSI and prediabetes and diabetes, the connection between HSI and glycemic progression is still being explored. This research seeks to clarify the association between HSI and glycemic progression risk among a Chinese demographic.

High-resolution anorectal manometry (HARM) is widely used for diagnosis and assessment of constipation and fecal incontinence. However, limited information is available on HARM-identifiable characteristics in patients with functional anorectal pain (FARP). This study explored the pathogenesis of FARP by investigating their anorectal physiological and psychological characteristics using HARM.

Solid pseudopapillary neoplasm of the pancreas (SPN) represents a rare form of low-grade malignant pancreatic cystic neoplasm. This study seeks to construct a predictive nomograph model for SPN recurrence.

Metabolic-associated fatty liver disease (MAFLD), a highly prevalent global liver disorder, requires early diagnosis and treatment to delay progression, yet lacks simple diagnostic tools. We aimed to evaluate the validity of the triglyceride-glucose index (TyG) and its related indexes in predicting MAFLD and pre-MAFLD among Chinese individuals.

The concept of pre-rehabilitation has been clinically implemented across various surgical fields; however, studies investigating its application in colonoscopy remain limited. This study aimed to evaluate the effectiveness, safety, and patient satisfaction of the pre-rehabilitation concept in bowel preparation for comfort colonoscopy among elderly Chinese patients.

To explore the impact of cumulative uric acid (cum UA) exposure on the incidence of metabolic dysfunction-associated fatty liver disease (MAFLD).

Chronic gastrointestinal (GI) diseases, including functional, inflammatory, and neoplastic conditions, are rising globally, partly due to modern lifestyles. The circadian rhythm, regulated by the central clock in the hypothalamus and synchronized with peripheral clocks in the gastrointestinal organs, orchestrates GI functions in response to environmental cycles. This clock is influenced by cues such as light, sleep, and eating times. The circadian machinery prepares the host to cope with environmental conditions to adjust cellular and organ function accordingly. Modern behaviors-like nighttime light exposure, travel across time zones, shift work, mistimed eating, and social jet lag-disrupt the circadian clock, affecting GI processes such as digestion, absorption, motility, intestinal barrier function, immune function, and the microbiome, promoting not only GI pathology, but also systemic inflammatory and metabolic disorders. This review summarizes the circadian rhythm's role in normal GI function, examines the consequences of circadian disruption in the GI tract, and discusses circadian-based therapeutic interventions. These interventions aim to realign the circadian clock with external cues or optimize medication timing according to biological rhythms. Understanding the role of the circadian clock in GI conditions can provide preventive and therapeutic opportunities to reduce the burden of GI diseases.

Cytomegalovirus (CMV), a common virus with double-stranded DNA, causes complications and occasional death post-liver transplantation. The pre-transplant donor's and recipient's serological status is the primary potential factor for CMV reactivation. Our research aimed to assess risk factors that predict the possibility of CMV infection in post-liver transplant patients.
