Pediatric to adult transition care in neurogastroenterology and motility: A position paper from the American Neurogastroenterology and Motility Society and European Society of Neurogastroenterology and Motility.

Transition services-programs that support adolescents and young adults (AYAs) as they move from a child-centered to a more autonomous, adult-orientated healthcare system-have been associated with improved short- and long-term healthcare outcomes. Unfortunately, there is a paucity of evidence exploring transition services within the neurogastroenterology and motility (NGM) field. The overall aim of this article, endorsed by the American Neurogastroenterology and Motility Society and European Society of Neurogastroenterology and Motility, is to promote a discussion about the role of transition services for patients with NGM disorders. The AYAs addressed herein are those who have: (a) a ROME positive disorder of gut-brain interaction (DGBI), (b) a primary or secondary motility disorder (including those with motility disorders that have been surgically managed), or (c) an artificial feeding requirement (parenteral or enteral tube feeding) to manage malnutrition secondary to categories (a) or (b). The issues explored in this position paper include the specific physical and psychological healthcare needs of patients with NGM disorders; key healthcare professionals who should form part of a secondary care NGM transition service; the triadic relationship between healthcare professionals, caregivers, and patients; approaches to selecting patients who may benefit most from transition care; methods to assess transition readiness; and strategies with which to facilitate transfer of care between healthcare professionals. Key areas for future research are also addressed, including the construction of NGM-specific transition readiness questionnaires, tools to assess post-transfer healthcare outcomes, and educational programs to train healthcare professionals about transition care in NGM.

Lack of awareness of neurogastroenterology and motility within medical education: Time to fill the gap.

Disorders of gut-brain interaction (DGBI), previously referred to as functional gastrointestinal disorders, affect 40.3% of adults in the general population and are diagnosed in 34.9% of new adult referrals to secondary care gastroenterology services. Despite their high prevalence, studies published in this issue of Neurogastroenterology and Motility by investigators based in Germany, the UK, and the USA demonstrate a mismatch between the clinical burden of DGBI and their representation in medical school and postgraduate curricula. This review outlines the salient findings of these studies and explores why and how negative perceptions toward DGBI exist, including factors related to misinformation and internalized stigma. The authors propose a selection of strategies to ameliorate physicians' attitudes toward and knowledge of neurogastroenterology and motility including linking trainees with dedicated clinician mentors with an interest in motility, exposing trainees to expert patients who can enhance empathy, extending Balint groups into gastroenterology training, and offering motility apprenticeships in specialist units. Urgent improvements to medical school and postgraduate curricula are required to ensure the longevity of this subspecialty field in gastroenterology, and to ensure the needs of a sizeable proportion of gastroenterology patients are appropriately met.

Review article: Emerging and current management of acute-on-chronic liver failure.

BACKGROUND: Acute-on-chronic liver failure (ACLF) is a clinically and pathophysiologically distinct condition from acutely decompensated cirrhosis and is characterised by systemic inflammation, extrahepatic organ failure, and high short-term mortality. AIMS: To provide a narrative review of the diagnostic criteria, prognosis, epidemiology, and general management principles of ACLF. Four specific interventions that are explored in detail are intravenous albumin, extracorporeal liver assist devices, granulocyte-colony stimulating factor, and liver transplantation. METHODS: We searched PubMed and Cochrane databases for articles published up to July 2023. RESULTS: Approximately 35% of hospital inpatients with decompensated cirrhosis have ACLF. There is significant heterogeneity in the criteria used to diagnose ACLF; different definitions identify different phenotypes with varying mortality. Criteria established by the European Association for the Study of the Liver were developed in prospective patient cohorts and are, to-date, the most well validated internationally. Systemic haemodynamic instability, renal dysfunction, coagulopathy, neurological dysfunction, and respiratory failure are key considerations when managing ACLF in the intensive care unit. Apart from liver transplantation, there are no accepted evidence-based treatments for ACLF, but several different approaches are under investigation. CONCLUSION: The recognition of ACLF as a distinct entity from acutely decompensated cirrhosis has allowed for better patient stratification in clinical settings, facilitating earlier engagement with the intensive care unit and liver transplantation teams. Research priorities over the next decade should focus on exploring novel treatment strategies with a particular focus on which, when, and how patients with ACLF should be treated.

Approaches to building rapport with patients.

In this article, I detail my rapport-building trial and error exercise and outline why addressing a patient's occupation at the beginning of a consultation worked during my history taking. Context permitting, addressing occupation can be useful when setting the tone and rhythm of a conversation, helping to focus explanations on the back of a patient's everyday experiences, and allowing a history-taker to address a patient's ideas, concerns and expectations more comfortably. Broaching occupation can also be a useful way to extrapolate information about disease risk factors and baseline understanding from the start. Whatever the rapport-building technique used, self-awareness seems to be a critical skill in this exercise, and an approach used with one patient may not necessarily be useful with another.

Tension hydrothorax in a patient with SARS-CoV-2 pneumonitis and pleural Mycobacterium tuberculosis.

Unilateral pleural effusions are uncommonly reported in patients with SARS-CoV-2 pneumonitis. Herein, we report a case of a 42-year-old woman who presented to hospital with worsening dyspnoea on a background of a 2-week history of typical SARS-CoV-2 symptoms. On admission to the emergency department, the patient was severely hypoxic and hypotensive. A chest radiograph demonstrated a large left-sided pleural effusion with associated contralateral mediastinal shift (tension hydrothorax) and typical SARS-CoV-2 changes within the right lung. She was treated with thoracocentesis in which 2 L of serosanguinous, lymphocyte-rich fluid was drained from the left lung pleura. Following incubation, the pleural aspirate sample tested positive for Mycobacterium tuberculosis This case demonstrates the need to exclude non-SARS-CoV-2-related causes of pleural effusions, particularly when patients present in an atypical manner, that is, with tension hydrothorax. Given the non-specific symptomatology of SARS-CoV-2 pneumonitis, this case illustrates the importance of excluding other causes of respiratory distress.

Superior ophthalmic vein thrombosis secondary to COVID-19: an index case.

Superior ophthalmic vein thrombosis is a very rare condition, known to have a profound negative impact on vision and eye movement function and is usually associated with orbital infections, inflammation, tumors, or carotid cavernous fistulae. There is an increased risk of arterial and venous thrombosis associated with COVID-19, the presence of which is related to a significantly increased risk of mortality. We report an index case of superior ophthalmic vein thrombosis in a 61-year-old male patient who was diagnosed with COVID-19 pneumonitis and a concomitant saddle pulmonary embolus. He was swiftly treated with low molecular weight heparin which led to the resolution of the thrombosis within 3 weeks. This case highlights the importance of considering this entity in the context of COVID-19 as well as providing prompt treatment to reduce the risk of complications.

The relationship between seasonality, latitude and tuberculosis notifications in Pakistan.

BACKGROUND: Pakistan ranks amongst the top 20 highest burden tuberculosis (TB) countries in the world. Approximately 369,548 cases of TB (all forms) were notified in 2018, with an estimated incidence of 265 per 100,000 people per year. In other settings, TB has been shown to demonstrate seasonal variation, with higher incidence in the spring/summer months and lower incidence in the autumn/winter; the amplitude of seasonal variation has also been reported to be higher with increasing distance from the equator. METHODS: Notifications of newly-diagnosed pulmonary and extrapulmonary TB cases were obtained for 139 districts in Pakistan from 2011 to 2017. Data were provided by the Pakistan National TB Control Programme, Islamabad, Pakistan. Statistical analyses were performed to determine whether there was seasonal variation in TB notifications in Pakistan; whether the amplitude of seasonal variation in TB notifications varied according to latitude; whether the amplitude of seasonal variation of TB in Pakistan differed between extrapulmonary TB vs. pulmonary TB. To assess the quarterly seasonality of TB, we used the X-13-ARIMA-SEATS seasonal adjustment programme from the United States Census Bureau. The mean difference and corresponding 95% confidence intervals of seasonal amplitudes between different latitudes and clinical phenotype of TB were estimated using linear regression. RESULTS: TB notifications were highest in quarter 2, and lowest in quarter 4. The mean amplitude of seasonal variation was 25.5% (95% CI 25.0 to 25.9%). The mean seasonal amplitude of TB notifications from latitude 24.5°N- < 26.5°N was 29.5% (95% CI 29.3 to 29.7%) whilst the mean seasonal amplitude of TB notifications from latitude 34.5°N - < 36.5°N was 21.7% (95% CI 19.6 to 23.9%). The mean seasonal amplitude of TB notifications across Pakistan between latitudes 24.5°N to 36.5°N reached statistically significant difference (p < 0.001). The amplitude of seasonal variation was greater for extrapulmonary TB (mean seasonal amplitude: 32.6, 95% CI 21.4 to 21.8%) vs. smear positive pulmonary TB mean seasonal amplitude: 21.6, 95% CI 32.1 to 33.1%), p < 0.001. CONCLUSION: TB notifications in Pakistan exhibit seasonal variation with a peak in quarter 2 (April-June) and trough in quarter 4 (October-December). The amplitude of seasonality decreases with increasing latitude, and is more pronounced for extrapulmonary than for pulmonary TB.

The anatomical basis for transcutaneous auricular vagus nerve stimulation.

The array of end organ innervations of the vagus nerve, coupled with increased basic science evidence, has led to vagus nerve stimulation (VNS) being explored as a management option in a number of clinical disorders, such as heart failure, migraine and inflammatory bowel disease. Both invasive (surgically implanted) and non-invasive (transcutaneous) techniques of VNS exist. Transcutaneous VNS (tVNS) delivery systems rely on the cutaneous distribution of vagal afferents, either at the external ear (auricular branch of the vagus nerve) or at the neck (cervical branch of the vagus nerve), thus obviating the need for surgical implantation of a VNS delivery device and facilitating further investigations across a wide range of uses. The concept of electrically stimulating the auricular branch of the vagus nerve (ABVN), which provides somatosensory innervation to several aspects of the external ear, is relatively more recent compared with cervical VNS; thus, there is a relative paucity of literature surrounding its operation and functionality. Despite the increasing body of research exploring the therapeutic uses of auricular transcutaneous VNS (tVNS), a comprehensive review of the cutaneous, intracranial and central distribution of ABVN fibres has not been conducted to date. A review of the literature exploring the neuroanatomical basis of this neuromodulatory therapy is therefore timely. Our review article explores the neuroanatomy of the ABVN with reference to (1) clinical surveys examining Arnold's reflex, (2) cadaveric studies, (3) fMRI studies, (4) electrophysiological studies, (5) acupuncture studies, (6) retrograde tracing studies and (7) studies measuring changes in autonomic (cardiovascular) parameters in response to auricular tVNS. We also provide an overview of the fibre composition of the ABVN and the effects of auricular tVNS on the central nervous system. Cadaveric studies, of which a limited number exist in the literature, would be the 'gold-standard' approach to studying the cutaneous map of the ABVN; thus, there is a need for more such studies to be conducted. Functional magnetic resonance imaging (fMRI) represents a useful surrogate modality for discerning the auricular sites most likely innervated by the ABVN and the most promising locations for auricular tVNS. However, given the heterogeneity in the results of such investigations and the various limitations of using fMRI, the current literature lacks a clear consensus on the auricular sites that are most densely innervated by the ABVN and whether the brain regions secondarily activated by electrical auricular tVNS depend on specific parameters. At present, it is reasonable to surmise that the concha and inner tragus are suitable locations for vagal modulation. Given the therapeutic potential of auricular tVNS, there remains a need for the cutaneous map of the ABVN to be further refined and the effects of various stimulation parameters and stimulation sites to be determined.

Use of autologous fat grafting in reconstruction following mastectomy and breast conserving surgery: An updated systematic review protocol.

INTRODUCTION: Use of autologous fat grafting (AFG) for breast reconstructive surgery is gaining acceptance, but concerns regarding its efficacy and safety remain. We present a protocol for a systematic review that aims to update the findings since our previous systematic review on a number of outcomes of AFG. METHODS: The systematic review has been registered a priori (UIN: reviewregistry308). All study designs, including randomised controlled trials, cohort studies, case-controlled studies and case reports/series, reporting original data, on women undergoing AFG for breast reconstruction following mastectomy or breast conserving surgery, will be included. Six categorical outcomes will be assessed: oncological; clinical; aesthetic/functional; patient-reported; process; and radiological.The search strategy will be devised to investigate 'fat grafting and breast reconstruction'. Electronic databases will be searched, 01 April 2014 to 21 August 2017: PubMed, MEDLINE®, EMBASE, SCOPUS, CINAHL, PsychINFO, SciELO, The Cochrane Library, including the Cochrane Central Register of Controlled Trials (CENTRAL), Database of Abstracts of Reviews of Effect (DARE), the Cochrane Methodology Register, Health Technology Assessment Database, the NHS Economic Evaluation Databases and Cochrane Groups, ClinicalTrials.gov, Current Controlled Trials Database, the World Health Organisation (WHO) International Clinical Trials Registry Platform, UpToDate.com, NHS Evidence and the York Centre for Reviews and Dissemination. Grey literature will be searched. Two trained, independent teams will screen all titles and abstracts, and relevant full texts, for eligibility. Data will be extracted under standardised extraction fields into a preformatted database. ETHICS AND DISSEMINATION: The systematic review will be published in a peer-reviewed journal and presented at national and international meetings within fields of plastic, reconstructive and aesthetic surgery, and surgical oncology. The work will be disseminated electronically and in print. Brief reports of the review and findings will be disseminated to interested parties through email and direct communication. The review aims to guide healthcare practice and policy.
