Article Synopsis
  • The study investigated how ondansetron affects patients with diabetic gastroenteropathy (DGE) compared to a placebo.
  • Patients took ondansetron or a placebo for 4 weeks, and their symptoms and gastric emptying were monitored through various methods.
  • Ondansetron reduced feelings of fullness and belching during lipid infusions but did not significantly affect daily symptoms compared to placebo, although some patients showed potential for symptom improvement when ondansetron was effective during the lipid challenge.

Background: Although diabetic gastroenteropathy (DGE) is associated with small intestinal bacterial overgrowth (SIBO), most studies have evaluated SIBO with a hydrogen breath test, which may be affected by altered transit in DGE. The risk factors for the consequences of SIBO in DGE are poorly understood. We aimed to evaluate the prevalence of, risk factors for, and gastrointestinal symptoms associated with SIBO in patients with DGE.

Background & Aims: Although depletion of neuronal nitric oxide synthase (NOS1)-expressing neurons contributes to gastroparesis, stimulating nitrergic signaling is not an effective therapy. We investigated whether hypoxia-inducible factor 1α (HIF1A), which is activated by high O consumption in central neurons, is a Nos1 transcription factor in enteric neurons and whether stabilizing HIF1A reverses gastroparesis.

Methods: Mice with streptozotocin-induced diabetes, human and mouse tissues, NOS1 mouse neuroblastoma cells, and isolated nitrergic neurons were studied.

Background & Aims: Anorectal manometry (ARM) is a comprehensive diagnostic tool for evaluating patients with constipation, fecal incontinence, or anorectal pain; however, it is not widely utilized for reasons that remain unclear. The aim of this roundtable discussion was to critically examine the current clinical practices of ARM and biofeedback therapy by physicians and surgeons in both academic and community settings.

Methods: Leaders in medical and surgical gastroenterology and physical therapy with interest in anorectal disorders were surveyed regarding practice patterns and utilization of these technologies.

Introduction: Chronic idiopathic constipation (CIC) is a common disorder associated with significant impairment in quality of life. This clinical practice guideline, jointly developed by the American Gastroenterological Association and the American College of Gastroenterology, aims to inform clinicians and patients by providing evidence-based practice recommendations for the pharmacological treatment of CIC in adults.

Methods: The American Gastroenterological Association and the American College of Gastroenterology formed a multidisciplinary guideline panel that conducted systematic reviews of the following agents: fiber, osmotic laxatives (polyethylene glycol, magnesium oxide, lactulose), stimulant laxatives (bisacodyl, sodium picosulfate, senna), secretagogues (lubiprostone, linaclotide, plecanatide), and serotonin type 4 agonist (prucalopride).

Background And Objectives: Chronic constipation (CC) may be caused by defecatory disorders (DDs) and associated with reduced rectal sensation. Among patients with type 1 diabetes (T1D) and CC (T1DCC patients), the prevalence of DDs and reduced rectal sensation is unknown. We sought to compare complications of T1D, anorectal dysfunction, and CC symptoms, among T1DCC patients with versus without a DD.

Introduction: Epidemiological studies show correlations between constipation and development of Parkinson's disease (PD); however, few studies have explored the association between constipation and dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD), and multiple system atrophy (MSA). We sought to explore the lifelong association of constipation and PD, DLB, PDD, and MSA (α-Synucleinopathies), compared to age- and sex-matched controls.

Methods: Using the Rochester Epidemiology Project (REP), we established an incident cohort of clinically defined α-synucleinopathies.

The motor function of the gastrointestinal tract relies on the enteric nervous system, which includes neurons spanning from the esophagus to the internal anal sphincter. Disorders of gastrointestinal motility arise as a result of disease within the affected portion of the enteric nervous system and may be caused by a wide array of underlying diseases. The etiology of motility disorders may be primary or due to secondary causes related to infection or inflammation, congenital abnormalities, metabolic disturbances, systemic illness, or medication-related side effects.

Background: Some patients with inflammatory bowel disease (IBD) on immunosuppressive therapies may have a blunted response to certain vaccines, including the messenger RNA (mRNA) coronavirus disease 2019 (COVID-19) vaccines. However, few studies have evaluated the cell-mediated immune response (CMIR), which is critical to host defense after COVID-19 infection. The aim of this study was to evaluate the humoral immune response and CMIR after mRNA COVID-19 vaccination in patients with IBD.

Background: More common in older women than younger women, rectoceles may be secondary to pelvic floor weakness and/or pelvic floor dysfunction with impaired rectal evacuation. Rectoceles may be small (<2 cm), medium (2-4 cm), or large (>4 cm). Arguably, large rectoceles are more likely to be associated with symptoms (e.

Article Synopsis
  • - The study investigates the day-to-day reproducibility of high-resolution anorectal manometry (HR_ARM) measurements in diagnosing defecatory disorders, notably focusing on healthy women and constipated patients over a 15- to 40-day period.
  • - Results showed that anal resting and squeeze pressures, along with rectal balloon expulsion time (BET), varied between testing days for a significant portion of constipated patients, with 79% showing discrepancies in key measurements.
  • - Although overall HR_ARM metrics and BET were found to be reproducible, the variability in outcomes suggests that testing could yield inconsistent diagnostic results for constipated individuals.

Faecal incontinence, which is defined by the unintentional loss of solid or liquid stool, has a worldwide prevalence of ≤7% in community-dwelling adults and can markedly impair quality of life. Nonetheless, many patients might not volunteer the symptom owing to embarrassment. Bowel disturbances, particularly diarrhoea, anal sphincter trauma (obstetrical injury or previous surgery), rectal urgency and burden of chronic illness are the main risk factors for faecal incontinence; others include neurological disorders, inflammatory bowel disease and pelvic floor anatomical disturbances.
