OBJECTIVE: Considerable disparities exist in access to gastrointestinal (GI) care and digestive outcomes across gender, racial, and socioeconomic groups. We evaluated (1) whether adults with chronic GI symptoms from diverse demographic groups would use a digital digestive care programme and (2) the effects of participation on GI symptom severity and other patient-reported outcomes.
METHODS: Access to a digital digestive chronic care programme was provided to participants regardless of prior digestive diagnoses or symptoms for 90 days. The intervention included GI symptom tracking, personalised medical nutrition therapy, GI-specific health coaching, and targeted education on common GI symptoms. We assigned a Social Vulnerability Index (SVI) score to each participant according to their home address and compared baseline and end-intervention symptoms and other patient-reported outcomes by gender, race/ethnicity, and SVI.
RESULTS: Of the 1936 participants, mean age was 43.1 years; 67% identified as white/Caucasian, 11% Asian/Pacific Islander, 6% Hispanic/Latinx, 7% black/African American, and 7% of multiple races. Participants of all demographic groups used the app symptom logging, reviewed educational materials, and interacted with their care team and reported similar statistically significant improvements in GI symptoms (by the end of the intervention, 85% improved, p<0.05). Participants reported feeling greater control of their health (83%), better able to manage their digestive symptoms (83%), increased happiness (76%), and greater productivity at work (54%), with black/African Americans and Native Americans most likely to report these changes.
CONCLUSIONS: We conclude that a digital GI disease management programme may be of value in reducing disparities in access to GI care.

Metformin is the most prescribed and recommended drug for type 2 diabetes mellitus because of its better tolerability, pleiotropic benefits, and cost-effectiveness. Metformin inhibits hepatic glucose production and increases muscle glucose uptake. Metformin is also associated with gastrointestinal side effects like abdominal bloating, flatulence, diarrhea, nausea, and vomiting. Metformin-related gastrointestinal side effects are mainly due to alteration in gut microbiota, raised intestinal glucose, and increased ileal bile salt reabsorption. We report a case of a 62-year-old diabetic patient who presented with chronic diarrhea with a weight loss of 6 kg from the last six years after initiation of metformin. He underwent multiple investigations and was finally misdiagnosed with irritable bowel syndrome for years. After discontinuation of metformin, there was a significant improvement in gastrointestinal symptoms. Our case highlights the importance of metformin-induced chronic diarrhea if no other causes for the diarrhea are obvious in patients with type 2 diabetes taking metformin. Consideration of this potential side effect of metformin must be valuable to avoid unwarranted investigations, additional drug therapy, and annoyance of the patients.

Background Patients with an unknown cause for chronic diarrhoea will usually undergo a colonoscopy as part of the investigative work-up, and it is acceptable practice for the patients to undergo random biopsies. The optimum number of biopsies has yet to be established. This study investigated the implications of routine random biopsies for diagnosing microscopic colitis in patients 50 years and older who presented with chronic diarrhoea. Methodology A retrospective cohort study of a prospectively maintained internal hospital database across three tertiary teaching hospitals in Perth, Western Australia, on participants >50 years old who presented for an elective colonoscopy to investigate chronic diarrhoea between January 2016 and June 2019. Data was captured from medical records, imaging, colonoscopy, and histopathology reports, and patient follow-up was analysed using SPSS v.29 (IBM Corp., Armonk, NY). Results There were 216 patients, with the majority female (67%) and a mean age of 64.6 (SD±9.9). Microscopic colitis was identified in 7.4% (95% CI = 3.9-10.9%). Most positive biopsies (81.3%) were from the left colon. The median number of biopsies per case was seven (IQR=5). The median procedure duration and scope withdrawal time were 23 and eight minutes, respectively. Most of the procedures were done by a consultant (77%). Bowel was adequately prepped in 76.9% of the cases. Univariate analysis demonstrated that the rate of identification of microcolitis was associated with the number of biopsies taken; microcolitis positivity had a higher mean number of biopsies, 10.8 vs 6.7 (p<0.001). Key complications were a 30-day readmission rate, seven-day re-presentation with acute colitis, post-procedure bleeding, requiring further imaging or angioembolisation and increased length of stay on readmission. Conclusion The prevalence of positive biopsies for microcolitis is low (7.4%). Biopsies during colonoscopy are associated with clinically significant morbidity and health care costs. Most positive biopsies were attained from the left colon. It may be time to standardise practice in investigating microscopic colitis as a cause of chronic diarrhoea in patients > 50 years old.

UNASSIGNED: Dientamoeba fragilis (DF), the most common intestinal protozoal pathogen in affluent countries, causes asymptomatic or symptomatic infections with severity ranging from mild to disabling. Currently, many studies of treatment options only have small sample sizes and report results that are partly contradictory.
UNASSIGNED: Investigating data retrieved from Helsinki University Hospital and Helsinki City patient records, we searched for the most effective antiprotozoal in treating DF infections. To study microbiological clearance of DF, we collected laboratory results of control samples from patients given one of four commonly used antiprotozoals: doxycycline, metronidazole, paromomycin, or secnidazole. For patients symptomatic prior to antiprotozoal treatment, we also retrieved data on clinical outcomes. Furthermore, we explored factors associated with faecal clearance and clinical cure.
UNASSIGNED: A total of 369 patients (median age 38) and 492 treatment episodes were included. Paromomycin (n ​= ​297) proved effective (clearance rate 83%), showing strong association with faecal clearance (aOR 18.08 [7.24-45.16], p ​< ​0.001). For metronidazole the rate was 42% (n ​= ​84), for secnidazole 37% (n ​= ​79), and doxycycline 22% (n ​= ​32). In pairwise comparisons, paromomycin outdid the three other regimens (p ​< ​0.001, χ2 test). Faecal clearance was associated with clinical cure (aOR 5.85 [3.02-11.32], p ​< ​0.001).
UNASSIGNED: Faecal clearance, strongly associated with clinical cure, is most effectively achieved with a course of paromomycin, followed by metronidazole, secnidazole and doxycycline. Our findings will be useful in devising treatment guidelines for adults with symptomatic D. fragilis infection.

BACKGROUND: The purpose of this study was to understand the experiences of primary caretakers (PCTs) with a child diagnosed with celiac disease (CeD). There is paucity of research in understanding the experiences of PCTs of children with CeD in India.
METHODS: Purposive sampling was used to select PCTs of CeD-affected children from a tertiary hospital in New Delhi. Ten PCTs took part in the investigation. To gather the data, semi-structured interviews were held with participants. Hindi was used to administer the interviews.
RESULTS: The current study focused on the difficulties and worries PCTs experience in managing CeD. The main themes and sub-themes that emerged from the data were diagnosis of CeD (misdiagnosis of CeD, late diagnosis of CeD, feelings at the time of diagnosis, help from a doctor/nutritionist at the time of diagnosis); characteristics of CeD (CeD as a new disease, CeD as an allergy); attitude towards wheat (wheat as a poison, ignorance regarding negative effect of wheat); influence of significant others (making fun of the child, queries from others are a source of worry, non-acceptance of celiac disease by others and pressure to give gluten to the child); issues in following gluten-free diet (GFD) (fear of cross-contamination, distrust on GFD available outside home, GFD is expensive, making GFD is difficult, joint family, non-adherence to GFD, making non-GFD along with GFD); effect of CeD (financial effect of CeD, effect on physical and mental health of the child and PCT, effect on social life, change in family dynamics, eating restrictions); management of CeD (GFD for the whole family to manage CeD, family support to manage CeD, adhering to GFD, early diagnosis); and concerns (future marital concern for the child, cure of CeD, proper physical growth).
CONCLUSIONS: The current study gave an understanding of how PCTs dealt with a child\'s CeD. The difficulties and worries of caretakers should be taken into consideration and appropriate recommendations made to lessen the strain of managing the child\'s CeD and the daily obstacles associated with it.

BACKGROUND: Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder in children. However, in primary care, it is still unknown whether there are differences in the prognosis of children with IBS compared to other diagnostic subgroups. Therefore, our aim was to describe the course of symptoms and health-related quality of life (HRQoL) for children with chronic gastrointestinal symptoms who either do or do not fulfil the Rome criteria for IBS in primary care. Second, we compared the diagnosis of the general practitioner (GP) with the Rome criteria.
METHODS: We conducted a prospective cohort study with 1-year follow-up, including children aged 4-18 years with chronic diarrhoea and/or chronic abdominal pain in primary care. During follow-up, the Rome III questionnaire, Child Health Questionnaire, and symptom questionnaires were completed.
RESULTS: A total of 60/104 children (57.7%) fulfilled the Rome criteria for IBS at baseline. Compared to children without IBS, children with IBS were more commonly referred to secondary care, used more laxatives, and more often developed chronic diarrhoea and low physical HRQoL during 1 year. The diagnosis \"IBS\" from the GP matched the Rome criteria for only 10% of children, as most were diagnosed with \"Constipation.\"
CONCLUSIONS: There seems to be a difference in the treatment and prognosis of symptoms and HRQoL between children with and without IBS in primary care. This suggests that it is relevant to differentiate between these groups. The evaluation and use of feasible criteria to define IBS in different healthcare settings remains subject for further studies.

UNASSIGNED: Probiotics may be an ideal choice for these patients, given it can improve the defecation and quality of life of individuals with chronic diarrhoea. However, evidence-based medical research is still limited to support its use as a diarrhoea agent.
UNASSIGNED: A randomized, double-blind, placebo-controlled clinical trial is designed to pinpoint the efficiency and possible action modes of probiotics for chronic diarrhoea. 200 eligible volunteers with chronic diarrhoea are randomly assigned to a probiotic group (orally taking Lactobacillus plantarum p9 probiotics powder) or a placebo group. Except an independent project administrator who will be responsible for unblinding, the other researchers are blinded. Primary outcome is diarrhoea severity score, and secondary outcomes include weekly mean frequency of defecation, weekly mean stool appearance score, weekly mean stool urgency score, emotional state score, gut microbiome, and faecal metabolome. Each outcome measure will be assessed at the timepoints of pre-administration (day 0), administration (day 14 and/or 28), and post-administration (day 42) to identity inter- and intra-groups differences. Adverse events will be recorded to evaluate the safety of L. plantarum p9.
UNASSIGNED: The study protocol will provide high-quality evidence for the use of probiotics as a diarrhoea agent when it is strictly conducted out, providing evidence regarding whether and to what extent L. plantarum p9 can improve the defecation and well-being of individuals with chronic diarrhoea.
