Review article: do stimulant laxatives damage the gut? A critical analysis of current knowledge.

Stimulant laxatives are well established as first- or second-line treatments for constipation and although they have a reliable therapeutic effect, alleged safety concerns still exist, particularly with long-term use. The potential harmful effects on the gastrointestinal system (including carcinogenicity) of the long-term use of diphenylmethane [bisacodyl, sodium picosulfate (SPS)] and senna stimulant laxatives were assessed in a comprehensive review of the publications identified in literature searches performed in PubMed and Embase up to and including June 2023. We identified and reviewed 43 publications of interest.

Clinical trial: predictive factors for response to gut-directed hypnotherapy for refractory irritable bowel syndrome, a post hoc analysis.

Background: Gut-directed hypnotherapy is effective for patients with irritable bowel syndrome (IBS). Despite its considerable evidence base, gut-directed hypnotherapy is not widely available and remains a limited resource. This emphasises the need to select patients who are most likely to benefit.

The national prevalence of disorders of gut brain interaction in the United Kingdom in comparison to their worldwide prevalence: Results from the Rome foundation global epidemiology study.

Background: There are minimal epidemiological data comparing the burden of disorders of gut brain interaction (DGBI) in the UK with other countries. We compared the prevalence of DGBI in the UK with other countries that participated in the Rome Foundation Global Epidemiology Study (RFGES) online.

Methods: Participants from 26 countries completed the RFGES survey online including the Rome IV diagnostic questionnaire and an in-depth supplemental questionnaire with questions about dietary habits.

Face-to-face interviews versus Internet surveys: Comparison of two data collection methods in the Rome foundation global epidemiology study: Implications for population-based research.

Background And Aims: The Rome Foundation Global Epidemiology Study (RFGES) assessed the prevalence, burden, and associated factors of Disorders of Gut-Brain Interaction (DGBI) in 33 countries around the world. Achieving worldwide sampling necessitated use of two different surveying methods: In-person household interviews (9 countries) and Internet surveys (26 countries). Two countries, China and Turkey, were surveyed with both methods.

A comparative study of disorders of gut-brain interaction in Western Europe and Asia based on the Rome foundation global epidemiology study.

Objective: Many studies have been published on disorders of the gut-brain interaction (DGBI) in Asia and Western Europe, but no previous study has directly assessed the difference between the two regions. The aim was to compare the prevalence of DGBI in Asia and Western Europe.

Methods: We used data collected in a population-based Internet survey, the Rome Foundation Global Epidemiology Study, from countries in Western Europe (Belgium, France, Germany, Netherlands, Italy, Spain, Sweden, and the United Kingdom) and Asia (China, Japan, South Korea, and Singapore).

Current Practices, Experiences, and Views in Clinical Hypnosis: Findings of an International Survey.

An online survey of 691 clinicians who use hypnosis was conducted in 31 countries to gain a broad real-world picture of current practices, views, and experiences in clinical hypnosis. Among 36 common clinical uses, stress reduction, wellbeing and self-esteem-enhancement, surgery preparations, anxiety interventions, mindfulness facilitation, and labor and childbirth applications were the most frequently rated as highly effective (each by ≥70% of raters) in the clinicians' own experience. Adverse hypnosis-associated effects had been encountered by 55% of clinicians but were generally short-lived and very rarely judged as serious.

Randomised, placebo-controlled trial and meta-analysis show benefit of ondansetron for irritable bowel syndrome with diarrhoea: The TRITON trial.

Background: Ondansetron may be beneficial in irritable bowel syndrome with diarrhoea (IBS-D).

Aim: To conduct a 12-week parallel group, randomised, double-blind, placebo-controlled trial of ondansetron 4 mg o.d.

Patient satisfaction after remotely delivered gut-directed hypnotherapy for irritable bowel syndrome during the COVID-19 era: implications for future practice.

Objective: Gut-directed hypnotherapy (GDH) is an evidence-based treatment for irritable bowel syndrome (IBS). Adoption of remote GDH has been accelerated by the COVID-19 pandemic. We aimed to evaluate patient experience and satisfaction following remote GDH.

Recognizing and Defining Occasional Constipation: Expert Consensus Recommendations.

Constipation is a common problem, affects 15% of the population, and is often self-diagnosed and self-managed. Over the past 3 decades, there have been significant advances in our understanding and management of chronic constipation, with the emerging recognition that occasional constipation (OC) is another subtype that falls outside current classifications. The purpose of this review was to describe the process of developing and proposing a new definition for OC based on expert consensus and taking into consideration the multifactorial nature of the problem such as alterations in bowel habit that include stool frequency and difficulty with stool passage, perception of the sufferer, duration of symptoms, and potential responsiveness to treatment.

Experience and clinical efficacy of gut-directed hypnotherapy in an Asian population with refractory irritable bowel syndrome.

Background And Aim: Recent studies have highlighted the high worldwide prevalence of irritable bowel syndrome (IBS) and disparities in its management between ethnic groups. For instance, gut-directed hypnotherapy (GDH), one of the most effective evidence-based treatments for IBS, is not recommended in Asian countries partly due to lack of population-specific outcome data. In this context, we evaluated the outcomes of GDH in an Asian population.

Double-blinded randomised placebo controlled trial of enterosgel (polymethylsiloxane polyhydrate) for the treatment of IBS with diarrhoea (IBS-D).

Objective: Irritable bowel syndrome with diarrhoea (IBS-D) is a common and challenging condition that significantly reduces quality of life. Enterosgel (polymethylsiloxane polyhydrate) is an intestinal adsorbent which sequesters harmful molecules and is safe and effective in acute infective diarrhoea. This randomised controlled multicentre trial aimed to investigate its safety and efficacy in patients with IBS-D.

Guidelines for the Assessment of Efficacy of Clinical Hypnosis Applications.

Research on the efficacy of hypnosis applications continues to grow, but there remain major gaps between the science and clinical practice. One challenge has been a lack of consensus on which applications of hypnosis are efficacious based on research evidence. In 2018, 6 major hypnosis organizations collaborated to form the Task Force for Establishing Efficacy Standards for Clinical Hypnosis.

A double-blind randomised placebo-controlled trial investigating the effects of lesogaberan on the objective cough frequency and capsaicin-evoked coughs in patients with refractory chronic cough.

Objective: Baclofen is a centrally acting γ-aminobutyric acid type B (GABA) receptor agonist which reduces gastro-oesophageal reflux and suppresses the cough reflex; however, central nervous system side-effects limit its use. Lesogaberan is a novel peripherally acting GABA agonist, but its effects on refractory chronic cough are unknown.

Design: We performed a single-centre, placebo-controlled, double-blind randomised crossover study in patients with chronic cough, refractory to the treatment of underlying conditions.

The symptom burden of Irritable Bowel Syndrome in tertiary care during the COVID-19 pandemic.

Background: The COVID-19 pandemic caused unprecedented disruption to healthcare services worldwide with well-documented detrimental effects on mental health. Patients with refractory disorders of gut-brain interaction such as Irritable Bowel Syndrome (IBS) seen in tertiary care tend to exhibit higher levels of psychological comorbidity, but the impact of the pandemic on IBS symptom severity in tertiary care is unknown.

Methods: As part of routine clinical care, consecutive tertiary referrals with refractory IBS patients prospectively completed a series of baseline questionnaires including IBS symptom severity score (IBS-SSS), non-colonic symptom score, Hospital Anxiety and Depression (HAD), and Illness impact scores.

Hypnotherapy for irritable bowel syndrome: patient expectations and perceptions.

Introduction: Numerous studies have shown that hypnotherapy (HT) is effective in irritable bowel syndrome (IBS) using traditional symptom severity end points. However, there is now interest in capturing the patient's perception of their illness and treatment because what patients expect from their treatment may differ from that of their healthcare provider.

Objective: To record patient perceptions and expectations of hypnotherapy as well as their symptom response.

Non-alcoholic fatty liver disease in irritable bowel syndrome: More than a coincidence?

Irritable bowel syndrome (IBS) and non-alcoholic fatty liver disease (NAFLD) are amongst the most common gastrointestinal and liver conditions encountered in primary and secondary care. Recently, there has been interest in the apparent co-incidence of NAFLD in patients with IBS mainly driven by improved understanding of their shared risk factors and pathophysiology. In this paper we summarize the shared risk factors which include; overlapping nutritional and dietary factors as well as shared putative mechanisms of pathophysiology.

Gut-focused hypnotherapy for children and adolescents with irritable bowel syndrome.

Objective: Severe irritable bowel syndrome (IBS) in school children and adolescents often leads to stigmatisation, social withdrawal, disrupted education and psychological distress. While there are few effective treatment options for IBS in this age group, gut-focused hypnotherapy (GFH) has shown promise in several trials. Unfortunately, GFH is not widely available, and clinical data outside of trials are scarce.

The Intestinal Gas Questionnaire (IGQ): Psychometric validation of a new instrument for measuring gas-related symptoms and their impact on daily life among general population and irritable bowel syndrome.

Background: Gas-related symptoms (GRS) are common in the general population (GPop) and among patients with disorders of gut-brain interactions but there is no patient-reported outcome evaluating these symptoms and their impact on daily life. We have previously developed a 43-item intestinal gas questionnaire (IGQ). The aim of the present study is to perform a psychometric validation of this instrument.

Greater Overlap of Rome IV Disorders of Gut-Brain Interactions Leads to Increased Disease Severity and Poorer Quality of Life.

Background And Aims: Conditions such as irritable bowel syndrome (IBS), functional dyspepsia, and functional constipation are among the prevalent gastrointestinal (GI) disorders classified as disorders of gut-brain interaction (DGBI), which can adversely affect the lives of sufferers. This study aimed to assess the degree and consequences of overlapping DGBI in a large population-based global scale.

Methods: Internet survey data from 54,127 adults (49.
