AI Article Synopsis
Article Abstract
Background: The Dietitian First Gastroenterology Clinic (DFGC) is an initiative that has been established in response to increased gastroenterology clinical demand resulting in increased number of patients waiting outside clinically recommended timeframes for specialist care. In this clinic, a dietitian is the primary contact for eligible patients referred to tertiary gastroenterology services and provides assessment and management strategies for patients under the clinical governance of a gastroenterology consultant. This service has previously been shown to reduce patient wait-times and induce excellent patient satisfaction. Evaluation of models of care need to consider patient health outcomes as a key indicator for overall health service effectiveness. The aim of this study was to determine the impact of DFGC on patient related health outcomes.
Methods: This study utilised a pretest-posttest design of patients seen in the DFGC who met the diagnostic criteria for irritable bowel syndrome using the Rome IV criteria Consenting participants completed the validated symptom-severity (IBS-SSS) and health-related quality of life (IBSQoL) assessments. Paired sample t-tests were used to analyse differences pre- and post-management in the DFGC. Univariate mixed effects analyses were conducted to examine associations between IBS-SSS, IBSQoL and patient demographics.
Results: A total of 80 of 122 patients seen in the DFGC were recruited and completed baseline data, with 60 (75%) completing follow up assessments. The average participant age was 35.6 years (75% female), and IBS subtypes; IBS-C 15.0%, IBS-D 38.3%, IBS-M 26.7% and IBS-U 20.0%. Participants experienced significant reductions in symptom severity based on IBS-SSS (300.1 vs 151.7; p < 0.001) independent of IBS subtype, age or gender, with 88% (53/60) experiencing a clinically significant improvement. Quality of life significantly improved for all IBS subtypes (p < 0.001) across all subscales except food avoidance (p = 0.11). There was a moderate negative correlation between the changes in symptom severity and quality of life (R = 0.432, p = 0.001).
Conclusions: Management in the DFGC provided positive patient health outcomes demonstrated by improvements in symptom severity and QoL.

Aim: Identify values that could predict the presence of increased pressure-pain sensitivity independent of the migraine cycle through a single assessment.
Methods: This was a secondary analysis of a previous study in which 198 episodic and chronic migraine patients were assessed during all phases of the migraine cycle. Pressure pain threshold (PPT) was assessed over the temporalis, cervical spine, hand, and leg.

Introduction: X842 is a new type of gastric acid-suppressing agent with a rapid onset of action and a long duration of effect. We aim to investigate the efficacy and safety of different doses of X842 versus lansoprazole in the treatment of patients with erosive esophagitis (EE).
Methods: This phase 2 study included 90 patients with EE (Los Angeles grades A-D) who were randomized (1:1:1) to receive oral low-dose X842 (50 mg/day, n=31), high-dose X842 (100 mg/day, n=31), or lansoprazole (30 mg/day, n=30) for 4 weeks.

Patients with cirrhosis have increased surgical risk and require care team expertise. We explored the association between center cirrhosis surgical volume and post-operative mortality in a large VA dataset. In this retrospective cohort study of 14,500 major surgeries in patients with cirrhosis, we found in adjusted analysis that high-volume centers (>16 surgeries in past year) had a 36% reduced hazard of post-operative mortality through 90 days versus low-volume centers (<9 surgeries in past year; hazard ratio 0.
