Translation, cultural adaptation, and evaluation of the psychometric properties of the Arabic Gastroesophageal Reflux Disease Questionnaire (Ar-GerdQ).

Background: Gastroesophageal reflux disease (GERD) is a common chronic digestive disease that affects people in different communities at different rates. Because of the absence of a validated Arabic tool to assess GERD symptoms, this study aimed to validate and culturally adapt the GERD questionnaire (GerdQ) tool to Arabic speakers.

Methods: Patients referred for pH testing with symptoms suggestive of GERD were recruited.

Factors underlying the long-term efficacy of faecal microbiota transplantation for patients with irritable bowel syndrome.

The long-term effects of the transplant dose, its administration route and repeated faecal microbiota transplantation (FMT) on the outcomes of FMT for patients with irritable bowel syndrome (IBS) are unknown. This study included 171 patients (125 females and 46 males): 90 g of donor feces was administered into the large intestine (LI) in 58, into the small intestine (SI) in 57, and into the SI twice (repeated SI) in 56. The patients provided a fecal sample and completed five questionnaires at the baseline and at 2 years after FMT.

Diet, Food, and Nutritional Exposures and Inflammatory Bowel Disease or Progression of Disease: an Umbrella Review.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), contributes to substantial morbidity. Understanding the intricate interplay between dietary factors and the incidence and progression of IBD is essential for developing effective preventative and therapeutic strategies. This umbrella review comprehensively synthesizes evidence from systematic reviews and meta-analyses to evaluate these complex associations.

Factors Underlying the Difference in Response to Fecal Microbiota Transplantation Between IBS Patients with Severe and Moderate Symptoms.

Background: Previous studies showed that patients with Severe IBS respond better to fecal microbiota transplantation (FMT) than do those with Moderate IBS.

Aims: The present study aimed to determine the effects of the transplant dose, route of administering it and repeating FMT on this difference.

Methods: This study included 186 patients with IBS randomized 1:1:1 into groups with a 90-g transplant administered once to the colon (LI), once to the duodenum (SI), or twice to the distal duodenum twice (repeated SI).

Increasing the transplant dose and repeating faecal microbiota transplantation results in the responses of male patients with IBS reaching those of females.

Background: Faecal microbiota transplantation (FMT) performed with a proper protocol is a safe treatment for IBS that has high efficacy and durable effects. Females have been reported to respond better than males to FMT. The present study aimed at determining whether increasing the transplant dose or repeating FMT improve the responses of males to FMT.
