Gut-focused hypnotherapy for Functional Gastrointestinal Disorders: Evidence-base, practical aspects, and the Manchester Protocol

Current Concepts in Gastroparesis and Gastric Neuromuscular Disorders-Pathophysiology, Diagnosis, and Management

Upper gastrointestinal concerns including gastroparesis-like symptoms affect a large portion of the population, and determining the culprit condition can be difficult due to largely shared symptoms, clinical course, pathophysiology, and treatment pathways. The understanding of gastric neuromuscular disorders (GNDs) is emerging as a heterogeneous group encompassing conditions from gastroparesis to functional dyspepsia with chronic nausea, early satiety, bloating, or abdominal pain, irrespective of gastric emptying. This article aims to review the current concepts in gastroparesis and GNDs including pathophysiology, diagnosis, and management. While some established standards in their diagnosis and management exist, a number of novel diagnostics are becoming available. Durable therapeutic options are notably limited for such common conditions with chronic and debilitating symptoms, and neuromodulators may play a key role in symptom control, which has been previously under-recognized and underutilized. Advances in both pharmacologic treatment targets as well as noninvasive and invasive interventions and devices show promise in improving the experience of patients with gastroparesis-like symptoms. At this time, treatment of GNDs requires comprehensive multidisciplinary care from providers to achieve successful treatment outcomes.

Management of Refractory Functional Gastrointestinal Disorders: What Role Should Psychiatrists Have?

Currently, it has been stated that psychiatric and psychological problems are equally paramount aspects of the clinical modulation and manifestation of both the central nervous and digestive systems, which could be used to restore balance. The present narrative review aims to provide an elaborate description of the bio-psycho-social facets of refractory functional gastrointestinal disorders, psychiatrists' role, specific psychiatric approach, and the latest psychiatric and psychological perspectives on practical therapeutic management. In this respect, "psyche," "psychiatry," "psychology," "psychiatrist," "psychotropic," and "refractory functional gastrointestinal disorders" (as the keywords) were searched in relevant English publications from January 1, 1950, to March 1, 2024, in the PubMed, Web of Science, Scopus, EMBASE, Cochrane Library, and Google Scholar databases. Eventually, the narrative technique was adopted to reach a compelling story with a high level of cohesion through material synthesis. The current literature recognizes the brain-gut axis modulation as a therapeutic target for refractory functional gastrointestinal disorders and the bio-psycho-social model as an integrated framework to explain disease pathogenesis. The results also reveal some evidence to affirm the benefits of psychotropic medications and psychological therapies in refractory functional gastrointestinal disorders, even when psychiatric symptoms were absent. It seems that psychiatrists are required to pay higher levels of attention to both the assessment and treatment of patients with refractory functional gastrointestinal disorders, accompanied by educating and training practitioners who take care of these patients.

Gastrointestinal, Behaviour and Anxiety Outcomes in Autistic Children Following an Open Label, Randomised Pilot Study of Synbiotics vs Synbiotics and Gut-Directed Hypnotherapy

Alterations of the microbiome-gut-brain (MGB) axis have been associated with autism spectrum disorder (ASD) and disorders of gut-brain interaction (DGBI). DGBI are highly prevalent in autistic children and are associated with worsening behaviour and anxiety. Treatments such as probiotics, prebiotics and gut-directed hypnotherapy (GDH) have shown efficacy in improving gut symptoms in children. The primary objective of the study was to compare changes in gastrointestinal (GI) scores following a 12-week intervention of synbiotics (prebiotic + probiotic) +/- GDH with a follow-up at 24 weeks. Secondary objectives included changes in behavioural and anxiety symptoms, while changes in gut microbiome composition were assessed as an exploratory objective. Children diagnosed with ASD aged 5.00-10.99 years (n = 40) were recruited and randomised (1:1) to a 12-week intervention of either synbiotics (SYN group) or synbiotics + GDH (COM group). Both the SYN and COM group experienced significant reductions in total GI scores post-intervention and at follow-up (p < 0.001), with no superiority of the COM treatment over the SYN treatment. The COM group showed beneficial reductions in anxiety scores (p = 0.002) and irritability behaviours (p < 0.001) which were not present in the SYN group. At follow-up, only those in the COM group maintained significant reductions in GI pain scores (p < 0.001). There were significant changes in gut microbiota such as increases in Bifidobacterium animalis and Dialister in both groups over time. In conclusion, synbiotics with or without GDH may help support standard care for autistic children who suffer comorbid DGBI. The trial was prospectively registered at clinicialtrials.gov on 16 November 2020 (NCTO4639141).

Behavioral Therapy for Functional Heartburn: Recommendation Statements

BACKGROUND & AIMS

Brain-gut behavior therapies (BGBT) are increasingly recognized as effective therapeutic interventions for functional heartburn. However, recommendations regarding candidacy for treatment, initial treatment selection, and navigating treatment non-response have not been established for functional heartburn specifically. The aim of this study was to establish expert-based recommendations for behavioral treatment in patients with functional heartburn.

METHODS

The validated RAND/University of California, Los Angeles Appropriateness Method was applied to develop recommendations. A 15-member panel composed of 10 gastrointestinal psychologists and 5 esophageal specialists ranked the appropriateness of a series of statements on a 9-point interval scale over 2 ranking periods. Statements were within the following domains: pre-therapy evaluation, candidacy criteria for BGBT, selection of initial BGBT, role of additional therapy for initial non-response to BGBT, and role of pharmacologic neuromodulation. The primary outcome was appropriateness of each intervention based on the recommendation statements.

RESULTS

Recommendations for psychosocial assessment (eg, hypervigilance, symptom-specific anxiety, health-related quality of life), candidacy criteria (eg, motivated for BGBT, acknowledges the role of stress in symptoms), and treatment were established. Gut-directed hypnotherapy or cognitive behavioral therapy were considered appropriate BGBT for functional heartburn. Neuromodulation and/or additional BGBT were considered appropriate in the context of non-response.

CONCLUSIONS

Gut-directed hypnotherapy and/or cognitive behavioral therapy are recommended as appropriate behavioral interventions for heartburn symptoms, depending on clinical indication, specific gut-brain targets, and preferred treatment modality (pharmacologic vs non-pharmacologic). Pre-therapy evaluation of psychosocial processes and candidacy for BGBT are important to determine eligibility for referral to psychogastroenterology services.

Gut-directed hypnosis and hypnotherapy for irritable bowel syndrome: a mini-review

Irritable bowel syndrome (IBS) is a frequent health condition which can be associated with functional disability and reduced health-related quality of life. IBS is classified as a disorder of the brain-gut axis. IBS is a very heterogenous condition with regards to the underlying pathophysiological mechanisms, the clinical picture and the amount of functional impairment. Within a biopsychosocial model of IBS psychosocial factors can play a role in the in the predisposition, triggering and development of chronicity. Somatic or psychosocial or a mixture of both factors might predominate in an individual patient. Gut-directed hypnosis is a special type of medical hypnosis combining standardised gut-directed suggestions (hypnosis) with suggestions tailored to the psychological characteristics of the patient (hypnotherapy). Of brain-gut behavioral therapies, cognitive bahvioral-based interventions and gut-directed hypnosis have the largest evidence for both short-term and long-term efficacy in controlled trials for IBS and are recommended by current European and North American gastroenterology guidelines as second line treatment options. Standardised gut-directed hypnosis is available by audiotapes and can be part of a multicomponent self-management approach by digital health applications. It can be used - based on the patient's preferences-as first line therapy for mild forms of IBS. Severe forms of IBS require face-to-face interdisciplinary management. Standardised gut-directed hypnosis and hypnotherapy tailored to the individual patient can be part of this approach.

Exploring the Interconnections of Functional Gut Disorders and Inflammatory Bowel Disease: A Narrative Review Article

Development and Current State of Digital Therapeutics for Irritable Bowel Syndrome

BACKGROUND & AIMS

Irritable bowel syndrome (IBS) is a common, debilitating disorder characterized by abdominal pain and disordered bowel habits. Current pharmacologic treatments often provide incomplete symptom relief and may be poorly tolerated. Furthermore, alleviation of gastrointestinal symptoms does not always translate into improved quality of life for IBS patients. Current treatment guidelines recommend brain-gut behavior therapy (BGBT) in conjunction with other IBS therapies, and, in randomized controlled trials, BGBT has been shown to improve symptoms, patient satisfaction, functioning, and quality of life. Access to BGBT is limited by lack of adequately trained gastrointestinal psychologists, patient time constraints, and cost. Furthermore, clinician knowledge that BGBT is specific, and different from psychotherapy approaches for common mental health disorders, may limit referrals even where available. This review provides an overview of the pathophysiology of IBS, disease burden, unmet therapeutic needs, evidence base of novel digital therapeutics for IBS, and guidance on the introduction and appropriateness of these interventions for patients.

METHODS

We searched the literature for available published data relating to the use of novel digital therapeutics to provide cognitive behavioral therapy and gut-directed hypnotherapy in the treatment of irritable bowel syndrome.

RESULTS

Clinical trial data support the development and utility of digital therapeutics designed to deliver self-guided cognitive behavioral therapy and hypnotherapy for the treatment of IBS.

CONCLUSIONS

BGBTs are effective, guideline-recommended treatments for IBS. Digital therapeutic devices offer accessible, cost-effective treatment options for delivery of adjunctive BGBT for the treatment of IBS. The decision to recommend digital BGBTs should be guided by careful patient assessment that includes mental health screening and risk assessment.

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.

AIM

To determine whether baseline patient characteristics were predictive of response to gut-directed hypnotherapy in patients with IBS METHODS: We conducted a secondary analysis of outcomes of 448 patients with refractory Rome III IBS who participated in a randomised study confirming non-inferiority of 6 compared to 12 sessions of gut-directed hypnotherapy. We compared baseline patient characteristics, including age, sex, IBS subtype, quality of life and IBS-Symptom Severity Scale (IBS-SSS), non-colonic symptom score and Hospital Anxiety and Depression (HAD) score between responders and non-responders. We defined response as ≥50-point decrease in IBS-SSS or ≥30% reduction in pain severity scores.

RESULTS

Overall, 76.3% achieved ≥50-point decrease in IBS-SSS. Responders had a higher baseline non-colonic symptom score (p = 0.005). Those who achieved ≥30% improvement in abdominal pain scores (59.8%) had higher baseline IBS-SSS (p = 0.03), and lower baseline HAD-depression score (p = 0.012). Fifty-four patients (12%) dropped out of gut-directed hypnotherapy. Compared to completers, dropouts had higher baseline HAD-anxiety score (p = 0.034).

CONCLUSIONS

These data suggest that patients with a higher burden of gastrointestinal and extraintestinal symptoms are most likely to benefit from gut-specific behavioural intervention for refractory IBS. Clinical assessment of gastrointestinal, somatic and psychological symptom profiles may play a role in selecting patients for gut-directed hypnotherapy.

The Role of the Nurse in the Management of Irritable Bowel Syndrome: A Narrative Review

Irritable bowel syndrome (IBS) is characterized by chronic symptoms of abdominal pain in association with changes in bowel habits. Abdominal pain is the most debilitating symptom for IBS patients, and its management is one of the greatest challenges for gastroenterologists. In recent years more evidence has arisen about an increasingly central role of the nurse in the management of gastrointestinal diseases including IBS. The aim of this narrative review is to analyse the latest evidence on the pathophysiology, diagnosis, and treatment of IBS patients with a specific focus on the role of the nurse in its management.

Practical multidisciplinary framework for the assessment and management of patients with unexplained chronic aerodigestive symptoms

OBJECTIVE

Patients experiencing unexplained chronic throat symptoms (UCTS) are frequently referred to gastroenterology and otolaryngology outpatient departments for investigation. Often despite extensive investigations, an identifiable structural abnormality to account for the symptoms is not found. The objective of this article is to provide a concise appraisal of the evidence-base for current approaches to the assessment and management of UCTS, their clinical outcomes, and related healthcare utilisation.

DESIGN

This multidisciplinary review critically examines the current understanding of aetiological theories and pathophysiological drivers in UCTS and summarises the evidence base underpinning various diagnostic and management approaches.

RESULTS

The evidence gathered from the review suggests that single-specialty approaches to UCTS inadequately capture the substantial heterogeneity and pervasive overlaps among clinical features and biopsychosocial factors and suggests a more unified approach is needed.

CONCLUSION

Drawing on contemporary insights from the gastrointestinal literature for disorders of gut-brain interaction, this article proposes a refreshed interdisciplinary approach characterised by a positive diagnosis framework and patient-centred therapeutic model. The overarching aim of this approach is to improve patient outcomes and foster collaborative research efforts.

The Challenge of Fibromyalgia Efficacy of Hypnosis in Alleviating the Invisible Pain: A Narrative Review

Fibromyalgia syndrome (FMS) is a multifaceted and incapacitating functional pain syndrome characterized by continuous, severe, widespread musculoskeletal pain. FMS is associated with other symptoms such as fatigue, nonrestorative sleep, cognitive/emotional dysfunction, and diminished health-related quality of life. The pathogenesis of FMS is still not fully understood, but an increasing amount of evidence supports the link between childhood/adulthood emotional, physical, sexual abuse or neglect and the development of FMS. Managing and treating FMS patients can be challenging because the syndrome is refractory to most treatments. However, psychological interventions, particularly hypnotherapy, have been shown to be effective in the cognitive modulation of fibromyalgic pain. FMS patients may benefit from hypnotherapy alone or in combination with standard medical therapy. Symptom-oriented hypnosis aims to reduce pain, fatigue, sleep problems, anxiety, and depression, while hypnotherapy focuses on resolving emotional conflicts and unresolved traumas associated with FMS. In conclusion, hypnosis may be a useful and safe adjunct tool for managing chronic pain and dysfunctional symptoms in challenging fibromyalgic patients.

Managing pain in irritable bowel syndrome: current perspectives and best practice

INTRODUCTION

Irritable bowel syndrome (IBS) is characterized by chronic symptoms (>6 months) of abdominal pain in combination with a disturbed bowel habit. There is an association between the intensity of abdominal pain and the need for health care utilization. A bidirectionally disordered gut-brain interaction is central in the pathophysiology of IBS where a number of factors, gastrointestinal and non-gastrointestinal, can contribute to the illness experience. In order to treat abdominal pain in IBS, mapping these factors in a multidimensional clinical profile is helpful.

AREAS COVERED

This review covers basic epidemiology and pathophysiology of abdominal pain in IBS, the diagnostic approach, and a multidimensional treatment model where the management of abdominal pain is in focus.

EXPERT OPINION

A personalized treatment of abdominal pain in IBS is possible in patients who understand the diagnosis, the potential of therapies used, and where a good continuity in the patient-doctor relationship is established.

Non-pharmacologic approaches to treatment of pediatric functional abdominal pain disorders

Functional abdominal pain disorders (FAPDs) affect up to 25% of children in the United States. These disorders are more recently known as disorders of "brain-gut" interaction. The diagnosis is based on the ROME IV criteria, and requires the absence of an organic condition to explain the symptoms. Although these disorders are not completely understood, several factors have been involved in the pathophysiology including disordered gut motility, visceral hypersensitivity, allergies, anxiety/stress, gastrointestinal infection/inflammation, as well dysbiosis of the gut microbiome. The pharmacologic and non-pharmacologic treatments for FAPDs are directed to modifying these pathophysiologic mechanisms. This review aims to summarize the non-pharmacologic interventions used in the treatment of FAPDs including dietary modifications, manipulation of the gut microbiome (neutraceuticals, prebiotics, probiotics, synbiotics and fecal microbiota transplant) and psychological interventions that addresses the "brain" component of the brain-gut axis (cognitive behavioral therapy, hypnotherapy, breathing and relaxation techniques). In a survey conducted at a large academic pediatric gastroenterology center, 96% of patients with functional pain disorders reported using at least 1 complementary and alternative medicine treatment to ameliorate symptoms. The paucity of data supporting most of the therapies discussed in this review underscores the need for large randomized controlled trials to assess their efficacy and superiority compared to other treatments.

Improving access to gut-directed hypnotherapy for irritable bowel syndrome in the digital therapeutics' era: Are mobile applications a "smart" solution?

Gut-directed hypnotherapy (GDH) is a highly effective brain-gut behavioral therapy which is recommended in international guidelines for the treatment of irritable bowel syndrome (IBS). There is increasing recognition of the value of GDH as part of integrated care alongside medical and dietary approaches. This has led to recent innovations to widen access to GDH to meet the increasing demand. Recent advances include streamlined courses of individualized GDH, group therapy, and remote delivery. In this issue of Neurogastroenterology and Motility, Peters et al. retrospectively report outcomes of smartphone app-delivered GDH in a population with self-reported IBS. While adherence was low, those that completed smart phone-delivered GDH-achieved symptom benefit. This mini-review summarizes the current evidence-base for available modalities of GDH and discusses the current and future utility and development of mobile health applications in the digital therapeutics' era.

The Emerging New Reality of Hypnosis Teletherapy: A Major New Mode of Delivery of Hypnotherapy and Clinical Hypnosis Training

Remote hypnotherapy is a treatment that is increasingly being utilized internationally. Its adoption has been accelerated following the COVID-19 pandemic when infection control measures mandated its implementation. Remote hypnotherapy via video, rather than telephone therapy, appears to be more popular and effective, which appears to be acceptable to patients and - compared to face-to-face therapy - has the potential to improve access. In this state-of-the-art article, the authors therefore review the latest literature in this exciting field of remote teletherapy, discussing adoption of video hypnotherapy; its evidence, including efficacy compared to face-to-face therapy; patient satisfaction; advantages and disadvantages of teletherapy; as well as practical considerations and factors that should be considered when deciding on the mode of delivery. They also discuss training implications of the recent developments. Finally, they highlight areas for future research and development. Overall, it is likely that remote hypnotherapy via video platforms is here to stay long term and has potential to become the standard form of therapy worldwide. However, recent data suggest that there may still be a need for face-to-face therapy with patient choice being an important factor.

Approach to Disorders of Gut-Brain Interaction

Disorders of gut-brain interaction, previously known as functional gastrointestinal disorders (eg, functional dyspepsia and irritable bowel syndrome), are commonly encountered in both the primary care and gastroenterology clinics. These disorders are often associated with high morbidity and poor patient quality of life and often lead to increased health care use. The management of these disorders can be challenging, as patients often present after having undergone an extensive workup without a definite etiology. In this review, we provide a practical five-step approach to the clinical assessment and management of disorders of gut-brain interaction. The five-step approach includes (1) excluding organic etiologies of the patient's symptoms and using Rome IV criteria for diagnosis, (2) empathizing with the patient to develop trust and a therapeutic relationship, (3) educating the patient about the pathophysiology of these gastrointestinal disorders, (4) expectation setting with a focus on improving function and quality of life, and (5) establishing a treatment plan with central and peripherally acting medications and nonpharmacological modalities. We discuss the pathophysiology of disorders of gut-brain interaction (eg, visceral hypersensitivity), initial assessment and risk stratification, as well as treatment for a variety of diseases with a focus on irritable bowel syndrome and functional dyspepsia.

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.

Design

On completing 12 sessions of remote GDH via Skype using the Manchester protocol, patients with refractory IBS completed a feedback form on their experience. The proportion reporting positive outcomes (≥30% improvement in global IBS symptoms or abdominal pain, satisfaction, recommendation to family/friends) were compared by patient factors (age, gender, proximity, preferences).

Results

Of 52 patients completing the feedback form, 27 (52%) indicated that they would have opted for remote over face-to-face GDH, regardless of the pandemic situation. On a five-point scale (5=easy), patients rated the platform easy-to-use (mean 4.5±0.8) without impairment of communication (mean rating 4.6±0.8). Following remote GDH, 30/52 (58%) reported ≥30% global IBS symptom improvement, and 24/52 (46%) reported ≥30% pain reduction. 90% would recommend remote GDH to others. Only 39% felt they would have benefitted more from face to face. Those who would have chosen remote GDH regardless of the pandemic were more likely to be satisfied (p=0.01). Age, gender and proximity did not influence outcomes, satisfaction and likelihood of recommending remote GDH to others. Difficulties during remote sessions were infrequent in both those that were satisfied, and those that would have preferred face to face.

Conclusion

These data support the need to continue developing remote GDH in the post-COVID era but suggest that there is still a role for face-to-face GDH, with patient choice being an important factor.

Complementary and alternative medicine for functional dyspepsia: An Asian perspective

A considerable number of Asian patients with functional dyspepsia (FD) are searching for complementary and alternative medicine (CAM) because they are unsatisfied with conventional medical treatment. However, no article has focused on CAM for FD from Asian perspective. In Asian countries, many traditional herbal formulas, including Banha-sasim-tang, Soyo-san, Sihosogan-san, Yukgunja-tang, and Pyeongwi-san, are used in patients with FD. In the few blinded and placebo-controlled studies conducted, the weak evidence regarding the effectiveness of herbal prescriptions in patients with FD did not allow any conclusions to be made. The clinical efficacy and safety of STW-5 were proven in several prospective randomized controlled trials and systematic reviews. Hence, it was recently approved as a therapeutic option for the treatment of FD. Peppermint and caraway, FDgard, black seed oil, and Jollab have been used in patients with FD, but there is limited evidence supporting their use. Reviews of acupuncture in patients with FD showed inconsistent results: a Cochrane review reported a negative result, while other meta-analyses reported positive results. Psychotherapy, including hypnotherapy, psychoanalytic psychotherapy, and cognitive behavioral therapy, may be used in patients with FD, although it is only supported by weak evidence. Therefore, well-planned, large-scale studies are necessary to evaluate the efficacy of CAM in treating FD, especially in Asian countries.

British Society of Gastroenterology guidelines on the management of functional dyspepsia

Functional dyspepsia (FD) is a common disorder of gut-brain interaction, affecting approximately 7% of individuals in the community, with most patients managed in primary care. The last British Society of Gastroenterology (BSG) guideline for the management of dyspepsia was published in 1996. In the interim, substantial advances have been made in understanding the complex pathophysiology of FD, and there has been a considerable amount of new evidence published concerning its diagnosis and classification, with the advent of the Rome IV criteria, and management. The primary aim of this guideline, commissioned by the BSG, is to review and summarise the current evidence to inform and guide clinical practice, by providing a practical framework for evidence-based diagnosis and treatment of patients. The approach to investigating the patient presenting with dyspepsia is discussed, and efficacy of drugs in FD summarised based on evidence derived from a comprehensive search of the medical literature, which was used to inform an update of a series of pairwise and network meta-analyses. Specific recommendations have been made according to the Grading of Recommendations Assessment, Development and Evaluation system. These provide both the strength of the recommendations and the overall quality of evidence. Finally, in this guideline, we consider novel treatments that are in development, as well as highlighting areas of unmet need and priorities for future research.

Hypnobiome: A New, Potential Frontier of Hypnotherapy in the Treatment of Irritable Bowel Syndrome-A Narrative Review of the Literature

Increasing evidence suggests that the gut-brain axis may play a key role in health and disease via a bidirectional communication network involving neural and immunoendocrine pathways. This complex interplay deeply influences both gut microbiota and brain behavior. Pathobiome or gut dysbiosis is relevant for the pathogenesis of functional gastrointestinal disorders, such as IBS, chronic pain syndromes, and neurological and mental disorders. As a consequence, targeting the gut microbiota is emerging as a novel, effective therapeutic perspective. Among many treatment options, psychological interventions, including hypnosis, have been used to target the so-called psychobiome and its hypnotic analogue, i.e., hypnobiome, referring to their potential efficacy to modulate the mind-gut axis in IBS patients. A narrative review of the recent literature is provided and circumstantial evidence suggests that hypnobiome may represent a new promising frontier of hypnotherapy.

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.

Methods

Consecutive British Asian patients with refractory IBS who received 12‐sessions of GDH using the Manchester protocol were included. Patients were treated by a team including a therapist able to speak several Asian languages. All patients prospectively completed the following questionnaires before and after GDH: IBS symptom severity score (IBS‐SSS), hospital anxiety and depression scale (HADS), non‐colonic symptom score, and the quality‐of‐life (QOL) score. The primary outcome measure was response to GDH defined by ≥50‐point reduction in IBS‐SSS. Pre‐ and post‐treatment data were compared statistically.

Results

Forty‐four Asian patients with IBS (age 49 ± 13 years; 29 [66%] female; baseline IBS‐SSS: 332.8 ± 94.6) completed GDH. Overall, 37 of 44 (84%) achieved a ≥50‐point reduction in IBS‐SSS and 25 of 44 (57%) achieved ≥30% reduction in abdominal pain scores. Following GDH, there were also significant mean improvements in IBS‐SSS (−132.1, P < 0.0001), non‐colonic symptom score (P < 0.0001), QOL score (P < 0.0001), HADS‐anxiety (P < 0.0001), and HADS‐depression (P < 0.0001), compared with baseline.

Conclusion

Regardless of the ethnicity of the therapist, GDH was highly effective with similar response rates to outcomes in other IBS populations, supporting the development of GDH in Asian countries.

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.

METHODS

150 consecutive IBS patients (116 females, 34 males, aged 16-81 years) receiving hypnotherapy completed questionnaires recording IBS symptom severity, quality of life, noncolonic symptoms, anxiety and depression levels before and after treatment. Their expectations and perceptions of HT were also recorded, including a free text reflection.

RESULTS

121 patients (81%) responded to treatment consistent with our previous experience. Symptom severity scores, noncolonic symptoms, quality of life, anxiety and depression significantly all improved after HT (p < 0.001). Expectancy of an improvement with hypnotherapy was greater in those who did not respond to treatment (63%) than those who did (57%, p < 0.001). Scepticism and apprehension were common before treatment and replaced with enthusiasm afterwards. Free text responses after treatment were overwhelmingly positive. Patients also reported a variety of other benefits and even 20 of 29 symptom nonresponders (70%) still considered treatment worthwhile.

CONCLUSION

Although initially perceived negatively, hypnotherapy improved symptoms and resulted in a wide range of additional benefits. Expectation did not necessarily influence outcome. Recording IBS symptoms alone does not fully capture the patient's experience of treatment and needs to be considered in future research.

A Practical Approach to the Diagnosis and Treatment of Abdominal Bloating and Distension

Abdominal bloating and distension are highly prevalent symptoms that can negatively impact quality of life and lead to medical consultation. Despite their prevalence, symptoms of bloating and distension pose a unique diagnostic and therapeutic challenge, as they are inherently nonspecific symptoms with a complex etiology, and no uniform diagnostic or treatment algorithm currently exists. Additionally, bloating is common among disorders of gut-brain interaction, which can be difficult to treat. This article offers a practical approach for evaluating and treating symptoms of bloating and distension through discussion of 5 common etiologies: diet, small intestinal bacterial over-growth, constipation, visceral hypersensitivity, and abdomino-phrenic dyssynergia. An effective personalized evaluation and treatment plan can be established to address symptoms of bloating and distension through consideration of these etiologies in the context of the patient's individual characteristics and presentation.

An update on current treatment strategies for laryngopharyngeal reflux symptoms

Laryngopharyngeal reflux (LPR) is a syndrome caused by reflux of gastric contents into the pharynx or larynx, which leads to symptoms of throat clearing, hoarseness, pain, globus sensation, cough, excess mucus production in the throat, and dysphonia. LPR is a challenging condition, as there is currently no gold standard for diagnosis or treatment, and thus this presents a burden to the healthcare system. Strategies for treatment of LPR are numerous. Medical therapies include proton pump inhibitors, which are first line, H2 receptor antagonists, alginates, and baclofen. Other noninvasive treatment options include lifestyle therapy and the external upper esophageal sphincter compression device. Endoscopic and surgical options include antireflux surgery, magnetic sphincter augmentation, and transoral incisionless fundoplication. Functional laryngeal disorders and laryngeal hypersensitivity can present as LPR symptoms with or without gastroesophageal reflux disease. Though there are minimal studies in this area, neuromodulators and behavioral interventions are potential treatment options. Given the complexity of these patients and numerous available treatment options, we propose a treatment algorithm to help clinicians diagnose and triage patients into an appropriate therapy.

Functional Chest Pain and Esophageal Hypersensitivity: A Clinical Approach

Functional chest pain, functional heartburn, and reflux hypersensitivity are 3 functional esophageal disorders defined by the Rome IV criteria. Specific criteria, combining symptoms and the results of objective testing, allow for an accurate diagnosis of these conditions. Management may include medications targeted at optimizing acid suppression or neuromodulation, as well as a host of complementary or alternative treatment options. Psychological and behavioral interventions, such as cognitive behavioral therapy and hypnotherapy, have displayed substantial benefits in the treatment of functional chest pain and functional heartburn. Acid suppression and focused neuromodulation are key evidence-based treatment options for reflux hypersensitivity.

Review article: the effectiveness of group and self-help hypnotherapy for irritable bowel syndrome and the implications for improving patients' choice and access to treatment

BACKGROUND

Individual hypnotherapy (IH) is a recognised treatment for irritable bowel syndrome (IBS). However, it is not widely available to patients due to its resource-intensive nature, lack of adequately trained therapists, and scepticism about hypnosis. Non-individualised hypnotherapy approaches, such as group and self-help hypnotherapy, could maximise existing therapist resources by treating more patients at the same time, thus widening patient access to treatment without incurring additional expenditure.

AIMS

To investigate the research literature for non-individualised approaches to hypnotherapy for IBS and to determine their effectiveness for reducing symptom severity and/or providing adequate relief.

METHODS

A literature review of published peer-reviewed studies was conducted. Quantitative research was selected to determine the effectiveness of the interventions.

RESULTS

Ten studies were eligible for inclusion. Three delivered group hypnotherapy, three integrated hypnosis within a group concept, and four utilised a self-help home hypnotherapy treatment using audio recordings. Both group hypnotherapy for adults and the self-help home hypnotherapy treatment for children were effective interventions that may be non-inferior to IH for patients with mild-to-moderate symptoms. Treatment benefits were long-lasting. The evidence for the integrative group concept and home treatment for adults was less compelling.

CONCLUSIONS

Group hypnotherapy for adults, and self-help hypnotherapy for children, may be cost-effective treatments that can widen access for patients with milder IBS in primary care settings. Further research is needed to determine the effectiveness of group hypnotherapy for patients with severe, refractory IBS.

Review article: current and future treatment approaches for pain in IBS

BACKGROUND

Abdominal pain is a core symptom of IBS and a primary driver of care seeking. Visceral hypersensitivity is a key pathophysiological mechanism and therapeutic target for pain in IBS, with components of peripheral and central sensitisation and psychological factors.

AIM

To review current and future treatment approaches specifically for the pain component of IBS.

METHODS

Pubmed search terms included combinations of irritable bowel, pain, visceral hypersensitivity, novel, new, emerging, future and advances.

RESULTS

Established non-pharmacological treatments for IBS pain include the low FODMAP diet, probiotics and psychological interventions, especially hypnotherapy. Tricyclics remain the best evidenced pharmacological approach with GCC agonists, tenapanor, lubiprostone, eluxadoline and 5HT3 antagonists second line according to patient characteristics and availability. Less well-evidenced current options include anti-spasmodics, peppermint oil, SSRIs, SNRIs, alpha 2 delta ligands, melatonin and histamine antagonists. Patients are vulnerable to iatrogenesis and harmful approaches to be avoided include opioids and unwarranted surgical interventions. For severe pain, the concept of augmentation with combined gut-brain neuromodulators and psychotherapy in a multi-disciplinary setting is considered. A plethora of molecular targets and ligands are emerging from pre-clinical studies, together with early clinical evidence for a range of pharmacological, dietary, neurostimulation and novel psychological treatment delivery methods which are reviewed. The history of such emerging approaches, however, merits both caution and optimism in equal measure.

CONCLUSIONS

Despite good in-roads and emerging options, the management of abdominal pain remains one of the biggest challenges and research priorities for patients with IBS.

AGA Clinical Practice Update on Management of Chronic Gastrointestinal Pain in Disorders of Gut-Brain Interaction: Expert Review

DESCRIPTION

This expert review summarizes approaches to management of pain in disorders of gut-brain interaction. This review focuses specifically on approaches to pain that persist if first-line therapies aimed at addressing visceral causes of pain are unsuccessful. The roles of a therapeutic patient-provider relationship, nonpharmacologic and pharmacologic therapies, and avoidance of opioids are discussed.

METHODS

This was not a formal systematic review but was based on a review of the literature to provide best practice advice statements. No formal rating of the quality of evidence or strength of recommendation was performed. BEST PRACTICE ADVICE 1: Effective management of persistent pain in disorders of gut-brain interaction requires a collaborative, empathic, culturally sensitive, patient-provider relationship. BEST PRACTICE ADVICE 2: Providers should master patient-friendly language about the pathogenesis of pain, leveraging advances in neuroscience and behavioral science. Providers also must understand the psychological contexts in which pain is perpetuated. BEST PRACTICE ADVICE 3: Opioids should not be prescribed for chronic gastrointestinal pain because of a disorder of gut-brain interaction. If patients are referred on opioids, these medications should be prescribed responsibly, via multidisciplinary collaboration, until they can be discontinued. BEST PRACTICE ADVICE 4: Nonpharmacologic therapies should be considered routinely as part of comprehensive pain management, and ideally brought up early on in care. BEST PRACTICE ADVICE 5: Providers should optimize medical therapies that are known to modulate pain and be able to differentiate when gastrointestinal pain is triggered by visceral factors vs centrally mediated factors. BEST PRACTICE ADVICE 6: Providers should familiarize themselves with a few effective neuromodulators, knowing the dosing, side effects, and targets of each and be able to explain to the patient why these drugs are used for the management of persistent pain.

Effect of Hypnotism on the Severity of Gastrointestinal Symptoms and Quality of Life in Individuals With Irritable Bowel Syndrome

The current study aimed to determine the effects of hypnotism on the severity of gastrointestinal symptoms and quality of life in individuals with irritable bowel syndrome (IBS). This trial study was conducted on 100 people with IBS in Shiraz, Iran. Hypnotism of participants was performed in 1-hour sessions for the intervention group at Weeks 4 and 6. A demographic characteristic questionnaire, Gastrointestinal Symptom Rating Scale, and IBS Quality of Life Index were used for data collection. The severity of gastrointestinal symptoms of participants in the intervention group significantly improved at 6 and 15 weeks after hypnotherapy. These individuals also had a significantly better quality of life after 15 weeks of hypnotherapy. Hypnotherapy may be beneficial in reducing gastrointestinal symptoms and improving quality of life in individuals with IBS. Combining this method with medicinal treatments could be effective for patients and health systems. [Journal of Psychosocial Nursing and Mental Health Services, xx(x), xx-xx.].

British Society of Gastroenterology guidelines on the management of irritable bowel syndrome

Irritable bowel syndrome (IBS) remains one of the most common gastrointestinal disorders seen by clinicians in both primary and secondary care. Since publication of the last British Society of Gastroenterology (BSG) guideline in 2007, substantial advances have been made in understanding its complex pathophysiology, resulting in its re-classification as a disorder of gut-brain interaction, rather than a functional gastrointestinal disorder. Moreover, there has been a considerable amount of new evidence published concerning the diagnosis, investigation and management of IBS. The primary aim of this guideline, commissioned by the BSG, is to review and summarise the current evidence to inform and guide clinical practice, by providing a practical framework for evidence-based management of patients. One of the strengths of this guideline is that the recommendations for treatment are based on evidence derived from a comprehensive search of the medical literature, which was used to inform an update of a series of trial-based and network meta-analyses assessing the efficacy of dietary, pharmacological and psychological therapies in treating IBS. Specific recommendations have been made according to the Grading of Recommendations Assessment, Development and Evaluation system, summarising both the strength of the recommendations and the overall quality of evidence. Finally, this guideline identifies novel treatments that are in development, as well as highlighting areas of unmet need for future research.

Recent Advances in the Management of Severe Gastrointestinal Dysmotility

Severe gastrointestinal motility disorders with small bowel involvement continue to pose a major clinical challenge to clinicians, particularly because of the limitations of diagnostic tests and the lack of efficacious treatment options. In this article, we review current understanding and the utility of diagnostic modalities and therapeutic approaches, and describe how their limitations may potentially exacerbate prolonged suffering with debilitating symptoms, diagnostic delays, the risk of iatrogenic harm and increased healthcare utilisation in this group of patients. Moreover, observations from intestinal failure units worldwide suggest that this problem could be set to increase in the future, with reported trends of increasing numbers of patients presenting with nutritional consequences. Unfortunately, until recently, there has been a lack of consensus recommendations and guidance to support clinicians with their management approach. The aim of this narrative review is to summarise recent developments in this field following publication of an international census of experts, and subsequent clinical guidelines, which have emphasized the importance of holistic, multidisciplinary care. This is particularly important in achieving good clinical outcomes and ensuring the appropriate use of artificial nutritional support, in order to prevent iatrogenic harm. We discuss how these recent developments may impact clinical practice by supporting the development of specialised clinical services to deliver optimal care, and highlight areas where further research is needed.

Understanding racial disparities in the care of patients with irritable bowel syndrome: The need for a unified approach

Irritable bowel syndrome (IBS) is a highly prevalent disorder of gut-brain interaction, which significantly erodes the quality of life of those it affects. Recent studies have confirmed that its prevalence varies quite markedly between countries, implying that it is affected by cultural and socioeconomic factors. In an important study, Silvernale at al. have recently reported racial disparities including potential referral biases, with reduced opportunities to access specialist care and differing patterns of healthcare utilization affecting ethnic minority populations with IBS. Similar disparities have also been reported for other gastrointestinal disorders. In this paper, we, therefore, discuss the potential implications of such disparities and how they can impact clinical outcomes, and discuss ways in which this problem could be addressed, and highlighting areas for future research.

Of bowels, brain and behavior: A role for the gut microbiota in psychiatric comorbidities in irritable bowel syndrome

BACKGROUND

The gastrointestinal microbiota has emerged as a key regulator of gut-brain axis signalling with important implications for neurogastroenterology. There is continuous bidirectional communication between the gut and the brain facilitated by neuronal, endocrine, metabolic, and immune pathways. The microbiota influences these signalling pathways via several mechanisms. Studies have shown compositional and functional alterations in the gut microbiota in stress-related psychiatric disorders. Gut microbiota reconfigurations are also a feature of irritable bowel syndrome (IBS), a gut-brain axis disorder sharing high levels of psychiatric comorbidity including both anxiety and depression. It remains unclear how the gut microbiota alterations in IBS align with both core symptoms and these psychiatric comorbidities.

METHODS

In this review, we highlight common and disparate features of these microbial signatures as well as the associated gut-brain axis signalling pathways. Studies suggest that patients with either IBS, depression or anxiety, alone or comorbid, present with alterations in gut microbiota composition and harbor immune, endocrine, and serotonergic system alterations relevant to the common pathophysiology of these comorbid conditions.

KEY RESULTS

Research has illustrated the utility of fecal microbiota transplantation in animal models, expanding the evidence base for a potential causal role of disorder-specific gut microbiota compositions in symptom set expression. Moreover, an exciting study by Constante and colleagues in this issue highlights the possibility of counteracting this microbiota-associated aberrant behavioral phenotype with a probiotic yeast, Saccharomyces boulardii CNCM I-745.

CONCLUSIONS AND INFERENCES

Such data highlights the potential for therapeutic targeting of the gut microbiota as a valuable strategy for the management of comorbid psychiatric symptoms in IBS.

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. Here, we evaluated outcomes from GFH in patients with IBS, aged ≤18 years, from a tertiary referral centre.

DESIGN/METHOD

Consecutive patients aged ≤18 years with severe IBS received 12 sessions of GFH, at weekly intervals, using the Manchester Protocol. Clinical outcomes data, including IBS Symptom Severity Score (IBS-SSS), Hospital Anxiety and Depression Scale (HADS), Non-colonic Symptom Score and Quality-of-Life (QoL) score, were collected prospectively, and compared pre-GFH and post-GFH. Clinical response was defined as ≥50 point reduction in IBS-SSS.

RESULTS

32 young patients fulfilling Rome III diagnostic criteria for IBS (median age 16 (range 8-18) years, n=23/32 (72%) female individuals) completed GFH. At baseline, the mean duration of IBS was 5.9±0.9 years, and the mean IBS-SSS was 313±14. After GFH, 28/32 (88%) responded, with a mean overall reduction in IBS-SSS -159±16 (p<0.0001), and 24/32 (75%) achieved ≥30% reduction in abdominal pain scores. GFH also improved: non-colonic symptoms (p<0.0001), HADS-anxiety (p<0.0001), HADS-depression (p=0.0002) and QoL Scores (p<0.0001).

CONCLUSION

GFH is highly effective in children and adolescents with IBS. Early intervention with GFH in childhood IBS may reduce the subsequent burden of this problem in adults.

Practitioners' experiences of using Gut Directed Hypnosis for irritable bowel syndrome: Perceived impact upon client wellbeing: A qualitative study

Gut Directed Hypnosis (GDH) is a specialised form of hypnotherapy originally developed to reduce gastrointestinal (GI) symptoms in individuals with Irritable Bowel Syndrome (IBS). IBS is a condition characterised by symptoms including bloating, abdominal pain and diarrhoea and/or constipation as well as psychosocial symptoms such as depression and anxiety. Although the specific mechanism of action remains unclear, it is suggested that GDH works on the brain-gut axis to improve GI symptoms, psychological functioning and overall wellbeing. The present study aimed to expand upon the knowledge surrounding GDH by exploring practitioners' experiences of using GDH for IBS and their perceptions of how it impacts upon client wellbeing. Six practitioners trained in GDH participated in one hour semi-structured interviews. Thematic Analyses (TA) was used to analyse data. Three major themes emerged from data including: predisposing personality traits and vulnerabilities associated with IBS; GDH as evidence-based practice; and the future evolution of GDH. The findings from this study add to the growing body of literature exploring the use of GDH for IBS, by incorporating the perspective of practitioners working within this field.

Remote buprenorphine-naloxone initiation as an essential service for people with chronic pain and opioid dependence during the COVID-19 pandemic: Case reports, clinical pathways, and implications for the future

Many health care professions have reacted swiftly to the COVID-19 pandemic. In-person care has been ramped down and telemedicine/telehealth has been thrust to the forefront of clinical care. For people living with chronic pain and often concomitantly dealing with opioid-related issues, this is a time of great stress. With population-wide movements to shelter in place, people living with pain are more isolated, more stressed, and more vulnerable to mental health concerns like depression and anxiety that can increase pain-related suffering. This article presents two case reports of patients struggling with chronic pain and opioid dependence in which a telemedicine-based buprenorphine-naloxone conversion was chosen as a treatment option by two Canadian programs: The Transitional Pain Service at the Toronto General Hospital in Toronto, Ontario, and The Opioid Deprescribing Program in Calgary, Alberta. Both cases presented highlight the use of telemedicine during the COVID-19 pandemic and suggest that there will be substantial need for these services well beyond the apex of the crisis. A buprenorphine-naloxone home induction protocol is presented and we provide insight into important lessons learned regarding the appropriate selection of patients with chronic pain struggling with opioid use disorder for buprenorphine-naloxone conversion. The provision of health care during the COVID-19 pandemic has rapidly forced practitioners to evolve novel health care practices, and these changes will have long-term implications.

Management of Irritable Bowel Syndrome: Physician-Dietitian Collaboration

Irritable bowel syndrome (IBS) affects 10%-15% of adults in the United States and 12% of the worldwide population. Gastroenterologists as well as primary care practitioners are likely to be the first resource for patients with gastrointestinal (GI) symptoms. IBS is difficult to diagnose, as it is a functional GI disorder, determined after ruling out a myriad of other diagnoses. The 2016 Rome IV criteria define IBS as "a functional bowel disorder in which recurrent abdominal pain is associated with defecation or a change in bowel habits. Disordered bowel habits are typically present (ie, constipation, diarrhea, or a mix of constipation and diarrhea), as are symptoms of abdominal bloating/distension occurring over at least 6 months and not less than 3 months." Treatment of IBS historically has been through medical management; however, nutrition management of IBS using the FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) elimination diet is now a recommended, first-line therapy. FODMAPs are short-chain, poorly absorbed carbohydrates that are associated with symptoms in people with IBS. This diet intervention can be quite challenging, and therefore, patients should meet with a qualified dietitian who can provide the complex diet information in a practicable form. Physician-dietitian collaboration is invaluable for IBS patients to achieve a successful outcome.

Functional gastrointestinal disorders in inflammatory bowel disease: Time for a paradigm shift?

Recent advances in biological therapies have revolutionalised and redefined treatment targets in inflammatory bowel disease (IBD). There is now a stronger emphasis on achieving the more stringent therapeutic goals of mucosal and histological healing, rather than clinical remission alone. Consequently, the treatment of refractory “functional” gastrointestinal symptoms, often attributed as the aftermath of previous inflammation, has recently become more prominent in quiescent disease. With further expected advances in anti-inflammatory treatments on the horizon, the burden of such symptoms in quiescent disease, which have been relatively neglected, is set to become an even bigger problem. In this article, we highlight the current state of research and understanding in this field, including recent developments and clinical practice guidelines on the diagnosis and management of functional gastrointestinal symptoms, such as irritable bowel syndrome and functional anorectal and pelvic floor disorders, in patients with quiescent IBD. These disorders are not only highly prevalent in these patients, they are often misdiagnosed, and are difficult to treat, with very few evidence-based therapies. Moreover, they are associated with substantial impairment in quality-of-life, considerable morbidity, and psychological distress. There is therefore an urgent need for a change in emphasis towards earlier recognition, positive diagnosis, and targeted treatment for patients with ongoing functional gastrointestinal symptoms in the absence of active IBD. This article also highlights the need for further research to develop much needed evidence-based therapies.

Multiple areas of the cerebral cortex influence the stomach

Despite the longstanding appreciation that how we move, think, and feel has an impact on stomach function, the areas of the cerebral cortex that are the origin of these influences are largely unknown. Here we identify the cortical areas that influence the rat stomach. Output neurons in the rostral insula are the major cortical source of influence over parasympathetic control of the stomach, whereas output neurons in sensorimotor areas of the cortex are the major source of influence over sympathetic control. Thus, cortical areas involved in action, interoception, and emotion differentially influence stomach function.

The central nervous system both influences and is influenced by the gastrointestinal system. Most research on this gut–brain connection has focused on how ascending signals from the gut and its microbiome alter brain function. Less attention has focused on how descending signals from the central nervous system alter gut function. Here, we used retrograde transneuronal transport of rabies virus to identify the cortical areas that most directly influence parasympathetic and sympathetic control of the rat stomach. Cortical neurons that influence parasympathetic output to the stomach originated from the rostral insula and portions of medial prefrontal cortex, regions that are associated with interoception and emotional control. In contrast, cortical neurons that influence sympathetic output to the stomach originated overwhelmingly from the primary motor cortex, primary somatosensory cortex, and secondary motor cortex, regions that are linked to skeletomotor control and action. Clearly, the two limbs of autonomic control over the stomach are influenced by distinct cortical networks.

Twitter debate: controversies in functional gastrointestinal disorders

The new 'Controversies In…' series for the Frontline Gastroenterology Twitter debates addressed the difficult area of functional gastrointestinal disorders, facilitated by the former editor-in-chief Anton Emmanuel. Key topics discussed included distinguishing functional dyspepsia from genuine gastroparesis, when we should investigate for bile acid malabsorption, the current treatments for constipation-predominant irritable bowel syndrome and, importantly, how to manage consultations with complex patients presenting with functional bowel disease. The debate generated over a million impressions on twitter and this article aims to summarise the key educational points from the event.
