Optimal Cutoffs of Fatty Liver Index and Hepatic Steatosis Index in Diagnosing Pediatric Metabolic Dysfunction-associated Steatotic Liver Disease.

Background & Aims: Despite the high global prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), effective noninvasive diagnostic tools in pediatric populations remain limited. We aimed to validate the predictive performance of the fatty liver index (FLI) and hepatic steatosis index (HSI) in diagnosing MASLD in the young population and propose optimal cutoff points for the diagnosis of MASLD and severe MASLD.

Methods: This cross-sectional study included data from 1158 and 203 youths from the United States National Health and Nutrition Examination Survey (NHANES) 2017 to 2020 and real-world clinical environments, respectively.

Methods: This cross-sectional study included data from 1,150 and 260 youths from the National Health and Nutrition Examination Survey (NHANES) and a real-world clinic, respectively. Hepatic steatosis was assessed using transient elastography and abdominal sonography.

2025 Seoul Consensus on Clinical Practice Guidelines for Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a chronic, disabling, and functional bowel disorder that significantly affects social functioning and reduces quality of life and increases social costs. The Korean Society of Neurogastroenterology and Motility published clinical practice guidelines on the management of IBS based on a systematic review of the literature in 2017, and planned to revise these guidelines in light of new evidence on the pathophysiology, diagnosis, and management of IBS. The current revised version of the guidelines is consistent with the previous version and targets adults diagnosed with or suspected of having IBS.

Role of endoscopy in patients with achalasia.

Achalasia is an esophageal motility disorder characterized by impaired lower esophageal sphincter relaxation and peristalsis of the esophageal body. With the increasing prevalence of achalasia, interest in the role of endoscopy in its diagnosis, treatment, and monitoring is also growing. The major diagnostic modalities for achalasia include high-resolution manometry, esophagogastroduodenoscopy, and barium esophagography.

Risk of all-cause and cause-specific mortality associated with immune-mediated inflammatory diseases in Korea.

It is unclear whether the higher mortality is attributable to the IMIDs themselves or to the higher prevalence of comorbidities in IMIDs. We aimed to investigate whether IMIDs confer a higher risk of mortality.
