Entrust Me: Embedding Entrustable Professional Activities in a Gastroenterology Residency Program.

Entrustable Professional Activities (EPAs) are defined as a process of gradually entrusting key tasks to specialty fellows during their training. EPAs are an important component of competency-based medical education; the concept of entrustment is also familiar and intuitive to clinical faculty, even inexperienced evaluators even if not termed as such. In this paper, we describe the process of how the authors adopted an established EPA framework for gastroenterology training, using EPAs to guide curriculum and faculty development and assessment in ten steps: (1) adopting an established framework, (2) mapping EPAs to relevant competencies, (3) specifying expected behaviors for competency of each EPA, (4) training faculty and fellows to have a shared mental model, (5) designing the training curriculum and educational strategies based on EPAs, (6) determining the assessment strategy, (7) designing the assessment tool, (8) ensuring clarity in how assessment data are used to make summative decisions, (9) changing feedback culture of fellows, and (10) using a longitudinal coaching system to improve EPA performance.

Effects of Ramadan fasting on fetal health: A systematic review.

BACKGROUND: Ramadan fasting (RF) is mandatory for all healthy Muslims in the ninth month of the Islamic calendar. Although pregnant women are exempt from fasting, many make the decision to practise it. Concerns that fasting during pregnancy harms the fetus remain, as there are no firm recommendations regarding its safety. OBJECTIVES: To provide a systematic review on the effects of RF on fetal health. SEARCH STRATEGY: We conducted a literature search for peer-reviewed articles through Ovid MEDLINE, PubMed, SCOPUS, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) until 31 December 2021. SELECTION CRITERIA: All case-control and observational cohort studies that reported on fetal outcomes of pregnant women who underwent RF for at least one day during pregnancy are included. DATA COLLECTION AND ANALYSIS: Two researchers independently reviewed the eligibility of all studies. A third researcher resolved any conflict between researchers. Findings are extracted from eligible papers and presented as narratives. MAIN RESULTS: Fourteen articles are included based on eligibility criteria, with a total sample size of 2889. Studies demonstrate negative associations between RF and neonatal weight, amniotic fluid index, preterm birth and growth parameters mainly during the second and third trimesters. However, the evidence is not strongly supported. CONCLUSION: There is limited data to elucidate the relationship between RF and fetal health, hence the need for more studies to provide a better understanding.

Protocolised Management of Cardiogenic Shock and Shock Teams: A Narrative Review.

Despite advances in therapy, the incidence of cardiogenic shock continues to increase, with significant mortality that has improved minimally over time. Treatment options for cardiogenic shock are complex and time-, resource-, and case volume-dependent, and involve multiple medical specialties. To provide early, more equitable, and standardised access to cardiogenic shock expertise with advanced therapies, cardiogenic shock teams with a protocolised treatment approach have been proposed. These processes have been applied across hospitals into integrated cardiogenic shock networks. This narrative review evaluates the role of cardiogenic shock teams, protocolised and regionalised shock networks, and the main individual components of protocolised shock management approaches.

Trends in Modifiable Risk Factors Amongst First Presentation ST Elevation Myocardial Infarction Patients in a Large Longitudinal Registry.

BACKGROUND: Recent studies suggest that the risk factor profile of patients presenting with ST elevation myocardial infarction (STEMI) is changing. AIM: The aim is to determine if there has been a shift of cardiovascular risk factors to cardiometabolic causes in the first presentation STEMI population. METHOD: We analysed data from a STEMI registry from a large tertiary referral percutaneous coronary intervention centre to determine the prevalence and trends of the modifiable risk factors of hypertension, diabetes, smoking and hypercholesterolaemia. PARTICIPANTS: Consecutive first presentation STEMI patients between January 2006 to December 2018. RESULTS: Among the 2,366 patients included (mean age 59, SD 12.66, 80% male) the common risk factors were hypertension (47%), hypercholesterolaemia (47%) current smoking (42%) and diabetes (27%). Over the 13 years, patients with diabetes (20% to 26%, OR 1.09 per year, CI 1.06-1.11, p<0.001) and patients with no modifiable risk factors increased (9% to 17%, OR 1.08, CI 1.04-1.11, p<0.001). Concurrently there was a fall in prevalence of hypercholesterolaemia, (47% to 37%, OR 0.94 per year, CI 0.92-0.96, p<0.001) and smoking (44% to 41%, OR 0.94, CI 0.92-0.96, p<0.001) but no significant change in rates of hypertension (53% to 49%, OR 0.99, CI 0.97-1.01, p=0.25). CONCLUSION: The risk factor profile of first presentation STEMI has changed over time with a reduction in smoking and a concurrent rise in patients with no traditional risk factors. This suggests the mechanism of STEMI may be changing and further investigation of potential causal factors is warranted for the prevention and management of cardiovascular disease.

Value of a Growth Mindset: Improving Endoscopy Coaching and Mentoring.

The teaching of endoscopic procedures to trainees has radically changed from the previous "see one, do one, teach one" approach to the method termed "competency-based medical education" (CBME), which has transformed endoscopic training. Successful implementation of a CBME program requires learners to direct their own learning. Learners with a growth approach are more likely to thrive in such a system since they are learning-oriented and not performance-oriented. This method dictates that endoscopy mentors take a longer-term and broader view of the development of the trainee and are vital to cultivate a growth mindset in learners, while an endoscopy coach focuses on helping trainees apply principles of mastery learning and deliberate practice. The goal of the authors was to describe some principles of effective coaching and mentoring methods as applied to endoscopy training.

Mindfulness-based cognitive therapy in functional dyspepsia: A pilot randomized trial.

BACKGROUND AND AIM: Patients with functional dyspepsia (FD) often have concomitant anxiety and depression. Mindfulness-based cognitive therapy (MBCT) combines the principles of cognitive behavioral therapy and mindfulness. It is a group-based therapy and has been shown to be efficacious in functional gastrointestinal disorders. There are no randomized controlled trials (RCTs) evaluating MBCT in FD. We aimed to evaluate feasibility and efficacy of MBCT in FD management. METHODS: We performed a mixed-method single-center pilot randomized trial of 28 patients fulfilling ROME-III criteria for FD. Fifteen patients were randomized to an 8-week MBCT program while 13 underwent treatment-as-usual (TAU). Patients completed questionnaires at baseline and at week 8. Two focus-groups were conducted. Feasibility of recruitment, acceptability of randomization, procedures and intervention, handout compliance and feasibility of quantitative measures were assessed. The primary outcome was subjective-clinical-assessment of FD symptoms (SCA-FD). Secondary outcome measures included Short-form Nepean Dyspepsia Index (SF-NDI), subjective-clinical-assessment of general health (SCA-GH), EuroQoL-Visual Analog Scale (EuroQoL-VAS), and Depression, Anxiety and Stress Scale-21 Items (DASS-21). RESULTS: Twelve of 15 patients in the MBCT group completed the program. There was a trend towards symptom improvement, with 90% in the MBCT group reporting improvement in SCA-FD compared with 45% in TAU(P = 0.063). Patients who underwent MBCT reported greater improvement in SF-NDI (mean change: -8.8 (SD: 7.5) vs -0.7 (7.2), P = 0.018) and DASS-21 (-19.8 (29.5) vs -5.5 (6.6) P = 0.13) compared with TAU. There was no difference in SCA-GH and EuroQoL-VAS. Based on SCA-FD improvement, the eventual RCT will require 50 patients (25 in each group). CONCLUSIONS: Mindfulness-based cognitive therapy is likely efficacious for FD, and it would be feasible to conduct a RCT.

The impact of the coronavirus disease 2019 pandemic on gastroenterologists in Southeast Asia: A mixed-methods study.

BACKGROUND AND AIM: The coronavirus disease 2019 pandemic has impacted gastroenterology practices worldwide; however, its protracted effects within Southeast Asia were unknown. The primary aim of the study was to determine the impact of the pandemic on clinical demands including burnout among gastroenterologists within the region. The secondary aim was to identify risk factors for burnout and determine regional stressors. METHODS: This was a mixed-methods study. Gastroenterologists were surveyed electronically between September 1 and December 7, 2020, via gastroenterology and endoscopy societies of Brunei, Indonesia, Malaysia, Philippines, Singapore, and Thailand. Quantitative and qualitative data were collected. The 22-item Maslach Burnout Inventory-Human Services Survey (MBI-HSS) was used to detect burnout. Quantitative data were non-parametric; non-parametric methods were used for statistical comparisons. Logistic regression was used to determine risk factors for burnout. Content analysis method was used to analyze qualitative data. Ethical approval was obtained. RESULTS: A total of 73.0% reported that they were still significantly affected by the pandemic. Of these, 40.5% reported increased workload and 59.5% decreased workload. Statistically significant differences in weekly working hours, endoscopy, and inpatient volumes were present. No differences were observed in outpatient volumes, likely because of telemedicine. Burnout was common; however, 50.1% of gastroenterologists were unaware of or did not have access to mental health support. This, as well as depression, being a trainee, and public sector work, increased burnout risk significantly. CONCLUSION: The effects of the pandemic are multifaceted, and burnout is common among Southeast Asian gastroenterologists. Safeguards for mental health are suboptimal, and improvements are urgently needed.

Pondering the Pandemic's Problems: A Program Director's Perspective.

The year 2020 was challenging for many fellowship programs with regard to training or even burnouts. In this article, I will reflect on being a new program director having to deal with new responsibilities amidst an evolving pandemic. I highlight ten takeaway reflections with the hope that others may find these relevant to their current situation as training program leaders and mentors.

Nonepithelial Tumors of the Larynx: Single-Institution 13-Year Review with Radiologic-Pathologic Correlation.

Nonepithelial tumors of the larynx are rare and represent a minority of all laryngeal neoplasms. Imaging has an important role in the diagnosis, treatment planning, and surveillance of these entities. However, unfamiliarity with these neoplasms can cause diagnostic difficulties for radiologists, especially because many of the imaging findings are nonspecific. By using a systematic approach based on clinical history, patient age and gender, lesion location, endoscopic results, and specific imaging findings, the differential diagnosis can often be narrowed. These tumors typically affect the submucosal layer, so if a tumor has an intact mucosa at endoscopy, a nonepithelial neoplasm is the most likely diagnosis. Nonepithelial tumors of the larynx can arise from the laryngeal cartilage or muscle or from the surrounding lymphoid tissue or blood vessels. Consequently, imaging findings typically correspond to the specific cell type from which it originated. Recognizing specific features (eg, metaplastic bone formation, macroscopic fat, or enhancement pattern) can often help narrow the differential diagnosis. In addition, identification of noncircumscribed borders of the lesion and invasion of the adjacent structures is key to diagnosis of a malignant process rather than a benign neoplasm. Understanding the pathologic correlation is fundamental to understanding the radiologic manifestations and is ultimately crucial for differentiation of nonepithelial laryngeal neoplasms.

Outrunning Burnout in a GI Fellowship Program During the COVID-19 Pandemic.

Many GI training programs have needed to adjust to the serious disruption to the training and education of fellows worldwide due to the COVID-19 pandemic. A silent problem that has arisen within programs is the issue of burnout among their trainees. Burnout is common among gastroenterologists, especially in fellows (Keswani et al. in Gastroenterology 147(1):11-14, 2014. https://doi.org/10.1053/j.gastro.2014.05.023 , Am J Gastroenterol 106(10):1734-1740, 2011. https://doi.org/10.1038/ajg.2011.148 ), with negative consequences to patient care and the safety of the trainees if not effectively dealt with. In this article, the author describes several additional factors potentially contributing to the intensifying burnout of the fellows in their home institution during this pandemic. Moreover, he describes specific practical interventions that the hospital and program have taken in order to address these factors.

Diaphragmatic Breathing Reduces Belching and Proton Pump Inhibitor Refractory Gastroesophageal Reflux Symptoms.

BACKGROUND & AIMS: In patients with gastroesophageal reflux disease (GERD) and excessive belching, most belches are supragastric, and can induce reflux episodes and worsen GERD. Supragastric belching (SGB) might be reduced with diaphragmatic breathing exercises. We investigated whether diaphragmatic breathing therapy is effective in reducing belching and proton pump inhibitor (PPI)-refractory gastroesophageal reflux symptoms. METHODS: We performed a prospective study of 36 consecutive patients with GERD refractory to PPI therapy and a belching visual analogue scale (VAS) score of 6 or more, seen at a gastroenterology clinic at a tertiary hospital in Singapore from April 2015 through October 2016. Patients underwent high-resolution manometry and 24-hour pH-impedance studies while they were off PPIs. Fifteen patients were placed on a standardized diaphragmatic breathing exercise protocol (treatment group) and completed questionnaires at baseline, after diaphragmatic breathing therapy, and 4 months after the therapy ended. Twenty-one patients were placed on a waitlist (control subjects), completed the same questionnaires with an additional questionnaire after their waitlist period, and eventually received diaphragmatic breathing therapy. The primary outcome was reduction in belching VAS by 50% or more after treatment. Secondary outcomes included GERD symptoms (evaluated using the reflux disease questionnaire) and quality of life (QoL) scores, determined from the Reflux-Qual Short Form and EuroQoL-VAS. RESULTS: Nine of the 15 patients in the treatment group (60%) and none of the 21 control subjects achieved the primary outcome (P < .001). In the treatment group, the mean belching VAS score decreased from 7.1 ± 1.5 at baseline to 3.5 ± 2.0 after diaphragmatic breathing therapy; in the control group, the mean VAS score was 7.6 ± 1.1 at baseline and 7.4 ± 1.3 after the waitlist period. Eighty percent of patients in the treatment group significantly reduced belching frequency compared with 19% in control subjects (P = .001). Treatment significantly reduced symptoms of GERD (the mean reflux disease questionnaire score decreased by 12.2 in the treatment group and 3.1 in the control group; P = .01). The treatment significantly increased QoL scores (the mean Reflux-Qual Short Form score increased by 15.4 in the treatment group and 5.2 in the control group; P = .04) and mean EuroQoL-VAS scores (15.7 increase in treatment group and 2.4 decrease in the control group). These changes were sustained at 4 months after treatment. In the end, 20 of the 36 patients who received diaphragmatic breathing therapy (55.6%), all with excessive SGB, achieved the primary outcome. CONCLUSIONS: In a prospective study, we found a standardized protocol for diaphragmatic breathing to reduce belching and PPI-refractory gastroesophageal reflux symptoms, and increase QoL in patients with PPI-refractory GERD with belching-especially those with excessive SGB.

Analysis and dissociation of anti-HIV effects of shRNA to CCR5 and the fusion inhibitor C46.

BACKGROUND: The gene therapeutic Cal-1 comprises the anti-HIV agents: (i) sh5, a short hairpin RNA to CCR5 that down-regulates CCR5 expression and (ii) maC46 (C46), a peptide that inhibits viral fusion with the cell membrane. These constructs were assessed for inhibition of viral replication and selective cell expansion in a number of settings. METHODS: HIV replication, selective outgrowth and cell surface viral binding were analysed with a single cycle infection assay of six pseudotyped HIV strains and a static and longitudinal passaging of MOLT4/CCR5 cells with HIV. Pronase digestion of surface virus and fluorescence microscopy assessed interactions between HIV virions and transduced cells. RESULTS: Cal-1 reduced CCR5 expression in peripheral blood mononuclear cells to CCR5Δ32 heterozygote levels. Even low level transduction resulted in significant preferential expansion in MOLT4/CCR5 gene-containing cells over a 3-week HIV challenge regardless of viral suppression [12.5% to 47.0% (C46), 46.7% (sh5), 62.2% (Dual), respectively]. The sh5 and Dual constructs at > 95% transduction also significantly suppressed virus to day 12 in the passage assay and all constructs, at varying percentage transduction inhibited virus in static culture. No escape mutations were present through 9 weeks of challenge. The Dual construct significantly suppressed infection by a panel of CCR5-using viruses, with its efficacy being independently determined from the single constructs. Dual and sh5 inhibited virion internalisation, as determined via pronase digestion of surface bound virus, by 70% compared to 13% for C46. CONCLUSIONS: The use of two anti-HIV genes allows optimal preferential survival and inhibition of HIV replication, with the impact on viral load being dependent on the percentage of gene marked cells.

Evaluation of symptomatic esophagogastric junction outflow obstruction.

BACKGROUND AND AIM: Esophagogastric junction outflow obstruction (EGJOO) may be due to anatomical abnormalities, but it is unclear how to evaluate them after high-resolution manometry. We aimed to determine (i) clinical and high-resolution manometry parameters differentiating anatomical EGJOO from functional EGJOO, (ii) investigations chosen and yield for anatomical EGJOO, and (iii) clinical outcomes of functional EGJOO. METHODS: Medical records of consecutive patients with symptomatic EGJOO from February 2012 to December 2015 were reviewed. EGJOO was defined as anatomical if investigations identified a macroscopic or microscopic pathology accounting for EGJOO. RESULTS: Forty of 292 (13.7%) had EGJOO, of which 6/40 (15%) had anatomical EGJOO (two PPI-responsive esophageal eosinophilia, two infiltrating cancers, and two external compressions). Anatomical EGJOO was more likely to present with dysphagia (100% vs 29.4%, P = 0.001) and less likely with regurgitation (0% vs 41.2%, P = 0.05). Anatomical EGJOO had higher frequencies of premature contraction (50% vs 5.9%, P = 0.003) and lower mean values of distal latency (5.6 +/- 1.3 vs 6.7 +/- 1.2, P = 0.004). Computed tomography scans revealed 50% (3/6) of etiologies of anatomical EGJOO. Approximately, 73.5% (25/34) of patients with functional EGJOO had spontaneous resolution of their symptoms. One underwent pneumatic dilatation with symptom resolution while remaining eight with persistent symptoms were attributed to gastroesophageal reflux disease. CONCLUSION: Anatomical causes are present in 15% of EGJOO. Evaluation is warranted especially in patients presenting with dysphagia. Esophageal biopsies, barium swallows, computed tomography scans, and endoscopic ultrasound are complementary in EGJOO evaluation. In patients with non-obstructive symptoms and no anatomical etiologies, monitoring for spontaneous resolution is an option.

The synergistic role of virtual coaching with simulation-based mastery learning for upper endoscopy.

Introduction: Our simulation-based mastery learning (SBML) curriculum, delivered in person, has been shown to successfully train novices in structured esophagogastroduodenoscopy (EGD). SBML with virtual coaching (VC) has the potential to improve the effectiveness and efficiency of endoscopy training and expand access to trainees from around the world. We share our observations conducting an EGD training course using SBML with VC. Methods: We conducted a 1-week virtual SBML course for novice trainees across seven academic centers in the USA and Asia. The cognitive component was delivered using an online learning platform. For technical skills, a virtual coach supervised hands-on training and local coaches provided assistance when needed. At the end of training, an independent rater assessed simulation-based performance using a validated assessment tool. We assessed the clinical performance of 30 EGDs using the ASGE Assessment of Competency in Endoscopy tool. We compared the trainees' scores to our cohort trained using in-person SBML training using non-inferiority t-tests. Results: We enrolled 21 novice trainees (mean age: 30.8 ± 3.6 years; female: 52%). For tip deflection, the trainees reached the minimum passing standard after 31 ± 29 runs and mastery after 52 ± 37 runs. For structured EGD, the average score for the overall exam was 4.6 ± 0.6, similar to the in-person cohort (4.7 ± 0.5, p = 0.49). The knowledge-based assessment was also comparable (virtual coaching: 81.9 ± 0.1; direct coaching: 78.3 ± 0.1; p = 0.385). Over time, our novice trainees reached clinical competence at a similar rate to our historical in-person control. Conclusions: VC appears feasible and effective for training novice gastroenterology trainees. VC allowed us to scale our SBML course, expand access to experts, and administer SBML simultaneously across different sites at the highest standards.

STAT3 protein up-regulates Gα-interacting vesicle-associated protein (GIV)/Girdin expression, and GIV enhances STAT3 activation in a positive feedback loop during wound healing and tumor invasion/metastasis.

Gα-interacting vesicle-associated protein (GIV) is a guanine nucleotide exchange factor that modulates key signaling pathways during a diverse set of biological processes, e.g. wound healing, macrophage chemotaxis, tumor angiogenesis, vascular repair, and cancer invasion/metastasis. We recently demonstrated that GIV is a metastasis-related protein, which serves both as a therapeutic target and as a biomarker for prognostication in cancer patients. Here we report the discovery that GIV is a direct target of the transcription factor signal transducer and activator of transcription-3 (STAT3), which is commonly known as a central regulator of tumor metastasis. We identified a single STAT3-binding site on the GIV promoter that was necessary and sufficient for transcriptional activation of GIV during wound healing and cancer invasion. Immunohistochemical analysis of breast carcinomas showed significant correlation between STAT3 activation and elevated GIV expression. Furthermore, we provide evidence that GIV positively autoregulates its own transcription by enhancing STAT3 activation via its guanine nucleotide exchange factor activity. Our findings provide mechanistic insights into how STAT3 activation is directly integrated with the receptor tyrosine kinase-GIV-G protein signaling axis. The forward feedback regulation we describe here between GIV and STAT3 may have profound therapeutic implications for cancer and epithelial regeneration/repair and could help invent novel approaches in treating and prognosticating cancer.

Medical Education Blog and Podcast Utilization During the COVID-19 Pandemic.

Introduction The coronavirus disease 2019 (COVID-19) pandemic disrupted traditional in-person learning models. Free Open Access Medical (FOAM) education resources naturally filled this void, so we evaluated how medical blog and podcast utilization changed during the early months of the pandemic. Methods Academic medical podcast and blog producers were surveyed on blog and podcast utilization immediately before (January-March 2020) and after (April-May 2020) the COVID-19 pandemic declaration and subsequent lockdown. Utilization is quantified in terms of blog post pageviews and podcast downloads. Linear regression was used to estimate the effect of publication during the COVID-19 period on 30-day downloads or pageviews. A linear mixed model was developed to confirm this relationship after adjustment for independent predictors of higher 30-day downloads or pageviews, using the podcast or blog as a random intercept. Results Compared to the pre-pandemic period, downloads and pageviews per unique blog and podcast publication significantly increased for blogs (median 30-day pageviews 802 to 1860, p<0.0001) but not for podcasts (median 30-day downloads 2726 to 1781, p=0.27). Publications that contained COVID-19 content were strongly associated with higher monthly utilization (ß=7.21, 95% CI 6.29-8.14 p<0.001), and even non-COVID-19 material had higher utilization in the early pandemic (median 30-day downloads/pageviews 868 to 1380, p<0.0001). Discussion The increased blog pageviews during the early months of the COVID-19 pandemic demonstrated the important role of blogs in rapid knowledge translation. Podcasts did not experience a similar increase in utilization.
