This study explores the feasibility of detecting gastroesophageal reflux disease (GERD) and Barrett’s esophagus (BE) using acoustic features extracted from speech recordings. GERD is a common condition affecting up to 27.8% of adults in the US. Chronic GERD is associated with BE, the precursor to esophageal adenocarcinoma. An automatic screening tool for GERD would improve clinical outcomes by improving early detection. Biomarkers based on acoustic features of speech may hold promise as hoarseness often co-occurs with GERD. The study cohort consisted of 49 adults with and 63 without GERD based on esophagogastroduodenoscopy or ambulatory pH studies. Speech, including sustained vowels, sentences, and reading, was systematically recorded. Voice quality was validated through auditory-perceptualratings with three speech-language pathologists. Automated, cross-validated, search across multiple machine and deep learning model types was performed using the recorded speech. Detection of condition presence and severity are explored, and model performance is reported, along with an assessment of the ability of acoustic features to discern across conditions.

INTRODUCTION: Outcomes and safety of budesonide maintenance therapy in microscopic colitis (MC) are not well known. METHODS: Adult residents of Olmsted County, Minnesota, diagnosed with MC (2002–2019) and treated with budesonide were identified using the Rochester Epidemiology Project. Response was assessed at 12 ± 4 weeks after initiation of therapy and defined as complete (resolution of diarrhea), partial (≥50% improvement in the number of bowel movements), nonresponse (<50% improvement), and intolerance (discontinued because of side effects). For safety outcomes, cases (budesonide maintenance) and MC controls (no budesonide therapy) were matched by sex and age at diagnosis (±2 years). RESULTS: A total of 450 patients were identified, of whom 162 (36.0%) were treated with budesonide for induction of clinical remission (median age 67 [23–91] years and 126 women [77.8%] ). Clinical outcomes for induction were as follows: 130 (80.2%) complete response, 22 (13.6%) partial response, 8 (4.9%) no response, and 2 (1.2%) intolerance. After induction, 96 (63.2%) had recurrence after discontinuation, of whom 27 (28.1%) required further budesonide induction treatment without maintenance, 56 (58.3%) required long-term budesonide maintenance, and 13 (13.5%) were treated with other therapies. Of those receiving budesonide maintenance, all responded (55 [98.2%] complete and 1 [1.8%] partial). No patient stopped maintenance from adverse events. The median duration of follow-up was 5.6 years (0.3–18.9). There was no significant difference between cases and controls in the incidence of osteopenia/osteoporosis, diabetes mellitus, hypertension, glaucoma, or cataracts. DISCUSSION: The long-term use of budesonide in MC seems to be effective and generally well tolerated with limited adverse effects.

INTRODUCTION: To describe the clinical, endoscopic, and histopathology features of esophageal graft-vs-host disease (GVHD). Methods: Patients with biopsy-proven esophageal GVHD diagnosed at Mayo Clinic between 2000 and 2021 were included. Results: In 43 esophageal patients, other organ GVHD was present in 58% before and 86% at esophageal GVHD diagnosis. Esophageal specific symptoms were uncommon (dysphagia 26% and odynophagia/heartburn 5%). Esophagogastroduodenoscopy was abnormal in 72% patients demonstrating erosive esophagitis, ulceration, desquamation, or rings/furrows in a diffuse or focal pattern. DISCUSSION: There should be a low threshold for esophageal biopsies for GVHD because esophageal symptoms and endoscopic findings may be nonspecific or absent.

ABSTRACT Bloom syndrome is an inherited disorder involving a characteristic phenotype of short stature, photosensitive rash, immunodeficiency, and an early predisposition to various cancers, including lymphoma and colorectal neoplasms. We present a patient with Bloom syndrome found to have a colonic mass secondary to diffuse large B-cell lymphoma highlighting the importance of cancer screening and surveillance in these patients.

INTRODUCTION: We examined national Google Trends and local healthcare utilization after 3 high-impact gastroenterology publications. METHODS: Changes in US Google Trends and Olmsted County health utilization were studied. RESULTS: Publication views within 30 days were 51,458 ( Imperiale ), 49,759 ( Pimentel ), and 18,750 ( Gomm ). Colonoscopy searches ( P = 0.04) and Cologuard tests performed ( P < 0.01) increased while colonoscopies decreased ( P < 0.01). Searches for rifaximin ( P = 0.05), irritable bowel syndrome ( P < 0.01), diarrhea ( P < 0.01), and rifaximin prescriptions ( P = 0.02) increased. Increase in hydrogen-2 blocker searches ( P = 0.02) and prescriptions ( P < 0.01) and gastroesophageal reflux disease ( P < 0.01) and dementia office visits ( P < 0.01) occurred. DISCUSSION: High-impact gastroenterology publications influence Google searches and local population-based healthcare utilization.

SummaryBackgroundNeoplasia detection rate, the proportion of Barrett's oesophagus patients with high‐grade dysplasia or oesophageal adenocarcinoma detected at index surveillance endoscopy has been proposed as a quality metric. However, the correlation between neoplasia detection rate and a clinically relevant outcome like post‐endoscopy Barrett's neoplasia remains unknown. Post‐endoscopy Barrett's neoplasia refers to the rate of high‐grade dysplasia or oesophageal adenocarcinoma on repeat endoscopy within one year of an index screening examination revealing non‐dysplastic Barrett's oesophagus or low‐grade dysplasia.AimTo assess correlation between neoplasia detection rate and post‐endoscopy Barrett's neoplasia.MethodsWe performed a systematic search of multiple databases from date of inception to June 2021 to identify cohort studies reporting both neoplasia detection rate and post‐endoscopy Barrett's neoplasia. Data from each study were pooled using a random effects model, and their correlation assessed using meta‐regression. Heterogeneity was assessed and a priori planned subgroup analyses were conducted.ResultsTen studies with 27 894 patients with Barrett's oesophagus were included. The pooled neoplasia detection rate and post‐endoscopy Barrett's neoplasia were 5.0% (95% CI: 3.4%‐7.1%, I2 = 97%) and 19.6% (95% CI: 10.1%‐34.7%, I2 = 96%), respectively. Meta‐regression revealed a statistically significant inverse relationship between the two variables (coefficient −3.50, 95% CI: −4.63 to −2.37, P < 0.01). With every 1% increase of neoplasia detection rate, post‐endoscopy Barrett's neoplasia decreased by 3.50%. Heterogeneity was high despite adjusting for study quality and performing several subgroup analyses.ConclusionWe observed a statistically significant inverse correlation between neoplasia detection rate and post‐endoscopy Barrett's neoplasia. Additional studies are needed to further validate this correlation.

INTRODUCTION: Esophageal epidermoid metaplasia (EEM) is a rare disease. METHODS: Patients with EEM diagnosed between 2014 and 2020 were reviewed. RESULTS: Forty EEM cases were identified. EEM occurred in 9 (23%) patients before, concordant, or after esophageal squamous cell carcinoma (ESCC). EEM was associated with previous esophageal lichen planus in 5 patients, Barrett's esophagus 7, and esophageal adenocarcinoma 1. EEM was focal in 28 (70%) or diffuse in 12 (30%) and not detected in 45% on recent previous endoscopy. DISCUSSION: EEM is a premalignant underrecognized condition associated with multiple conditions. Close follow-up or endoscopic treatment may be warranted because of its ESCC association.
