    Abstract Swallowing is a complex process involving the precise contractions of numerous muscles of the head and neck, which act to process and shepherd ingested material from the oral cavity to its eventual destination, the stomach. Over the past five decades, information from animal and human studies has laid bare the complex network of neurones in the brainstem, cortex and cerebellum that are responsible for orchestrating each normal swallow. Amidst this complexity, problems can and often do occur that result in dysphagia, defined as impaired or disordered swallowing. Dysphagia is common, arising from multiple varied disease processes that can affect any of the neuromuscular structures involved in swallowing. Post-stroke dysphagia (PSD) remains the most prevalent and most commonly studied form of dysphagia and, as such, provides an important disease model to assess dysphagia physiology and pathophysiology. In this review, we explore the complex neuroanatomical processes that occur during normal swallowing and PSD. This includes how strokes cause dysphagia, the mechanisms through which natural neuroplastic recovery occurs, current treatments for patients with persistent dysphagia and emerging neuromodulatory treatments.

    Abstract Introduction: SARC-F (Strength, Assistance in walking, Rise from a chair, Climb stairs and Falls) is a validated screening questionnaire for rapidly assessing sarcopenia in older adults with a variety of diseases while the Rockwood clinical frailty scale (RCFS) is a commonly used tool for assessing frailty in older adults. However, there are no data regarding the use of these tools in patients with type two intestinal failure (T2IF). We aimed to compare SARC-F and RCFS to bioelectrical impedance analysis (BIA) and anthropometry in patients with T2IF.
    Methods: In this cross-sectional study, patients with T2IF admitted to a national U.K. reference centre had SARC-F, RCFS, BIA and anthropometry performed. A SARC-F score ≥4 indicated potential sarcopenia while a RCFS ≥5 indicated frailty. Statistical analyses were conducted to assess correlation, concordance and differences between measurements.
    Results: The study comprised 76 patients, of whom 59.2 % were female, with a mean age of 56.5 years ± 16. Seventy percent of patients had short bowel syndrome as an underlying cause of IF. Thirty eight percent of patients had a SARC-F ≥4 and 20 % had a RCFS ≥5. SARC-F was correlated with RCFS (rs 0.43, p < 0.001), phase angle (PA) (rs -0.55, p < 0.001) and hand grip strength (HGS) (rs -0.34, p 0.004). RCFS was correlated with HGS (rs -0.31, p 0.009). Significant differences emerged between PA (p 0.002) and HGS (p 0.003) values in patients with SARC-F scores ≥4 and < 4 and with HGS for patients with RCFS ≥5 and < 5 (p 0.01). Patients with SARC-F scores ≥4 had longer lengths of stays than those with scores <4 (p 0.002). Compared to PA and HGS, SARC-F had sensitivities of 39 % and 37 % and specificities of 92 % and 73 % respectively.
    Conclusion: We demonstrated SARC-F is correlated with PA and HGS with comparable sensitivity and specificity to its original use in older individuals. There is a role for SARC-F as a means of rapidly assessing muscle quality and function in hospitalised patients with IF with RCFS providing some useful information about muscle function.

    Abstract Swallowing is a complex activity requiring a sophisticated system of neurological control from neurones within the brainstem, cerebral cortices and cerebellum. The cerebellum is a critical part of the brain responsible for the modulation of movements. It receives input from motor cortical and sensory areas and fine tunes these inputs to produce coordinated motor outputs. With respect to swallowing, numerous functional imaging studies have demonstrated increased activity in the cerebellum during the task of swallowing and damage to the cerebellum following differing pathological processes is associated with dysphagia. Single pulses of transcranial magnetic stimulation (TMS) have been applied to the cerebellum and have been shown to evoke motor responses in the pharynx. Moreover, repetitive TMS (rTMS) over the cerebellum can modulate cerebral motor (pharyngeal) cortical activity. Neurostimulation has allowed a better understanding of the connections that exist between the cerebellum and cerebral swallowing motor areas in health and provides a potential treatment for neurogenic dysphagia in illness. In this review we will examine what is currently known about the role of the cerebellum in the control of swallowing, explore new findings from neurostimulatory and imaging studies and provide an overview of the future clinical applications of cerebellar stimulation for treating dysphagia.

    Abstract 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.

    Abstract Background: Despite their high prevalence and burden, disorders of gut-brain interaction (DGBI) are undertaught and underrepresented in medical curricula. We evaluated the exposure of UK gastroenterology trainees to DGBI and their comfort managing these conditions.
    Methods: An electronic survey was distributed to trainees via UK training program directors. The survey included questions on stage of training; subspecialty interest; access to DGBI training opportunities, and comfort levels with DGBI diagnosis and management. Responses were compared between junior and senior trainees, by subspecialty interest (luminal and non-luminal), by geographical region, and training program size.
    Key results: One hundred twelve trainees from across the UK participated (21.4% of national training post holders). Exposure to DGBI lectures (32.8% junior vs. 73.3% senior trainees, p = 0.00003) and clinics (9.0% junior vs. 42.2% senior trainees, p = 0.00003), increased with seniority. Regardless of seniority, most trainees were rarely comfortable making a DGBI diagnosis (39.5% senior vs. 33.9% junior trainees, p = 0.69), and were not comfortable initiating neuromodulators (50% senior vs. 25.8% junior trainees, p = 0.08). Trainees without a luminal subspecialty interest (50%) accessed fewer DGBI clinics (p = 0.04), had less communication skills training (p = 0.04) and were less likely to have been observed during DGBI consultations (p = 0.002). Responses were similar across UK regions and did not differ between smaller and larger programs.
    Conclusions & inferences: DGBI training opportunities are limited in UK gastroenterology training across training grades. Most trainees lack confidence with DGBI diagnosis and management. Urgent interventions need to be targeted at all stages of training to ensure DGBI competencies for future gastroenterologists and improve patient outcomes.

    Abstract A 34-year-old man was admitted to hospital via the accident and emergency department with severe right-sided abdominal pain and raised inflammatory markers. His pain settled with analgaesia and he was discharged with a course of oral co-amoxiclav. He was readmitted to the hospital 7 days later reporting cough and shortness of breath. His chest X-ray showed a raised right hemi-diaphragm, presumed consolidation and a right-sided effusion. As a result, he was treated for pneumonia. Despite antibiotic therapy his C reactive protein remained elevated, prompting an attempt at ultrasound-guided drainage of his effusion. Finding only a small amount of fluid, a CT of the chest was performed, and this showed a subphrenic abscess and free air under the diaphragm. A CT of the abdomen was then carried out, showing a perforated appendix. An emergency laparotomy was performed, the patient's appendix was removed and the abscess drained.

    Abstract Dysphagia, which refers to difficult and/or disordered swallowing, is a common problem associated with various neurological diseases such as stroke, motor neuron diseases and neurodegenerative diseases. Traditionally, dysphagia treatments are either compensatory, which includes modifications of bolus texture or feeding posture, or rehabilitative, which includes behavioral exercises and sensory stimulation. Despite being widely adopted in clinical practice, recent views have challenged the clinical efficacy of these treatments due to the low level of evidence supported by mainly non-controlled studies. As such, with advancements in technology and scientific research methods, recent times have seen a surge in the development of novel dysphagia treatments and an increasing number of robust randomized controlled clinical trials. In this review, we will review the clinical evidence of several newly introduced treatments for dysphagia in the last two decades, including rehabilitative exercises, biofeedback, pharmacological treatments, neuromodulation treatments and soft robotics. Despite the recent improvements in the quality of evidence for the efficacy of dysphagia treatments, several critical issues, including heterogeneity in treatment regimens, long-term treatment effects, underlying mechanisms of some neuromodulation treatments, and the effects of these techniques in non-stroke dysphagia, remain to be addressed in future clinical trials.

    Abstract In the last two decades, the focus of neurogenic dysphagia management has moved from passive compensatory strategies to evidence-based rehabilitative approaches. Advances in technology have enabled the development of novel treatment approaches such as neuromodulation techniques, which target the promotion of neurological reorganization for functional recovery of swallowing. Given the rapid pace of development in the field, this review aims to summarize the current findings on the effects of neuromodulation techniques on the human swallowing system and evaluate their therapeutic potential for neurogenic dysphagia. Implications for future clinical research and practical considerations for using neuromodulation in clinical practice will also be discussed.

    Abstract Background: The majority of patients with Parkinson's disease (PD) develop oropharyngeal dysphagia during the course of their disease. However, the efficacy of dysphagia treatments for these patients remains controversial. Therefore, we conducted this systematic review and meta-analysis to evaluate treatment efficacy based on the evidence from randomized controlled trials (RCTs).
    Methods: Five electronic databases were systematically searched from inception date to April 2022. Two reviewers independently extracted and analyzed the data. The outcome measures were changes in swallowing-related characteristics based on instrumental swallowing assessments.
    Key results: An initial search identified 187 RCT studies of relevance. After screening, nine studies with a total sample size of 286 were included in the meta-analysis. The pooled effect size for all dysphagia treatments compared with control comparators was significant and medium (SMD [95% CI] = 0.58 [0.22, 0.94], p = 0.001; I
    Conclusions and inferences: Our results showed that overall, dysphagia treatments, particularly stimulation treatments, can potentially benefit PD patients. However, given the limited number of small RCTs for each type of treatment, the evidence remains weak and uncertain. Further large-scale, multicenter RCTs are warranted to fully explore their clinical efficacy in the PD population.

    Abstract 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,
    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.
