Sex differences impact ergonomic endoscopic training for gastroenterology fellows.

BACKGROUND AND AIMS: Endoscopic-related injuries (ERIs) for gastroenterologists are common and can impact longevity of an endoscopic career. This study examines sex differences in the prevalence of ERIs and ergonomic training during gastroenterology fellowship. METHODS: A 56-item anonymous survey was sent to 709 general and advanced endoscopy gastroenterology fellows at 73 U.S. training programs between May and June 2022. Demographic information was collected along with questions related to endoscopic environment, ergonomic instruction, technique, equipment availability, and ergonomic knowledge. Responses of female and male gastroenterology fellows were compared using χ2 and Fisher exact tests. RESULTS: Of the 236 respondents (response rate, 33.9%), 113 (44.5%) were women and 123 (52.1%) were men. Female fellows reported on average smaller hand sizes and shorter heights. More female fellows reported endoscopic equipment was not ergonomically optimized for their use. Additionally, more female fellows voiced preference for same-gender teachers and access to dial extenders and well-fitting lead aprons. High rates of postendoscopy pain were reported by both sexes, with significantly more women experiencing neck and shoulder pain. Trainees of both sexes demonstrated poor ergonomic awareness with an average score of 68% on a 5-point knowledge-based assessment. CONCLUSIONS: Physical differences exist between male and female trainees, and current endoscopic equipment may not be optimized for smaller hand sizes. This study highlights the urgent need for formal ergonomic training for trainees and trainers with consideration of stature and hand size to enhance safety, comfort, and equity in the training and practice of endoscopy.

Adverse Events of Endoscopic Clip Placement: A MAUDE Database Analysis.

BACKGROUND: Clips are endoscopic mechanical devices with tensile and closure strength that can approximate tissue and provide hemostasis through a tamponade effect. Clips are ubiquitously used in endoscopic practice, and numerous studies have validated the clinical efficacy of clips, with recent guidelines recommending them as a first-line intervention for recurrent and persistent nonvariceal gastrointestinal bleeding. However, the safety profile for these devices has yet to be delineated, thus, we aim to investigate this feature by examining the adverse events reported to the Food and Drug Administration. METHODS: Postmarketing surveillance data from the Food and Drug Administration Manufacturer And User Facility Device Experience database were analyzed from January 2012 to January 2021. The Manufacturer And User Facility Device Experience database is a reporting software and does not independently verify the details of complications. RESULTS: Two thousand five hundred forty reports were issued, of which 287 were patient adverse events and 2766 were device problems. Activation, separation, and positioning issues were most common. No consequences or clinically significant impact on patients were seen in 1968 reports. Foreign bodies were seen in 97 cases, hemorrhage in 57 cases, tissue damage in 42 cases, embedded clips in tissues/plaques in 16 cases, perforation in 15 cases, lacerations in 6 cases, and infection in 3 cases. CONCLUSIONS: While the most commonly reported device problems involved activation, separation, and positioning, most patients were clinically unaffected. Moreover, perforation and infection were exceedingly rare, further highlighting the safety profile of endoscopic clips.

Involvement in National Gastroenterological Societies for Professional Development and Career Advancement: Tips for Trainees.

Engaging with national gastroenterological (GI) societies offers a plethora of pathways for professional development at every career stage. While each society has a mission with distinct aims, which provides a different spectrum of opportunities, almost all societies share several common goals. Involvement in national GI organizations can not only help in professional advancement but can be a rewarding and meaningful way to contribute to our field. There are several benefits of engagement with national GI organizations and trainees should see what aligns with their goals to make the best of the opportunities offered by these organizations. These include education, scholarship, and research opportunities, establishing mentorship, developing leadership skills, and involvement in advocacy among many others. In this article, we aim to provide a trainee and early career gastroenterologist's perspective of various benefits of involvement in national GI societies and how it can help in professional development and career advancement.Please verify if the provided city name in Affiliation 2 is correct and amend if necessary.The city is correctPlease confirm the corresponding author is correctly identified and amend if necessary.Information for the corresponding author is correct.

Hospitalization Burden of Biliary Strictures and Cholangitis After Pancreaticoduodenectomy.

BACKGROUND: Postsurgical biliary disease in Roux-en-y and cholecystectomies has been investigated, but less literature exists regarding biliary complications after Whipple procedure (pancreaticoduodenectomy [PD]). Moreover, the hospital burden incurred after this complication has not been previously examined. The aim of this study is to assess the trends in hospitalization for biliary strictures and cholangitis after PD. MATERIALS AND METHODS: The National Inpatient Sample identified all cases with a PD and a primary diagnosis of biliary complication in 2014. Cases were identified using the International Classification of Diseases, Clinical Modification codes. Primary outcomes were association of biliary complications with mortality, cost of admission, and length of stay. RESULTS: A total of 10,145 patients in 2014 were documented with a previous PD. Mortality was 50-fold greater without biliary complications (2.7% versus 0.05%), but a 95% increased length of stay (25.8 d versus 13.2 d, P = 0.014) and 70% increased cost of admission ($293,894 versus $165,862, P = 0.092) occurred with biliary complications. Regression analysis revealed increased length of stay in all cohorts (adjusted odds ratio: 14.3, P = 0.007) and increased cost of admission with cholangitis (adjusted odds: 458283, P = 0.00). Finally, there was increased biliary strictures, cost of hospitalization, and length of stay from 2011 to 2014. CONCLUSIONS: Biliary disease due to the PD appears to longitudinally increase length of stay and cost of hospitalization. Compared with gastrointestinal bleed and delayed gastric emptying, biliary strictures and cholangitis are still very high acuity, requiring more extensive medical resources. Minimally invasive surgeries and robotics could play a vital role in minimizing biliary complications and the ensuing hospitalization burden.

Longitudinal genetic analyses of Staphylococcus aureus nasal carriage dynamics in a diverse population.

BACKGROUND: Staphylococcus aureus (SA) nasal colonization plays a critical role in the pathogenesis of staphylococcal infections and SA eradication from the nares has proven to be effective in reducing endogenous infections. To understand SA nasal colonization and its relation with consequent disease, assessment of nasal carriage dynamics and genotypic diversity among a diverse population is a necessity. RESULTS: We have performed extensive longitudinal monitoring of SA nasal carriage isolates in 109 healthy individuals over a period of up to three years. Longitudinal sampling revealed that 24% of the individuals were persistent SA nasal carriers while 32% were intermittent. To assess the genetic relatedness between different SA isolates within our cohort, multi locus sequence typing (MLST) was performed. MLST revealed that not only were strains colonizing intermittent and persistent nasal carriers genetically similar, belonging to the same clonal complexes, but strain changes within the same host were also observed over time for both types of carriers. More highly discriminating genetic analyses using the hypervariable regions of staphylococcal protein A and clumping factor B virulence genes revealed no preferential colonization of specific SA strains in persistent or intermittent carriers. Moreover, we observed that a subset of persistent and intermittent carriers retained clinically relevant community-acquired methicillin-resistant SA (CA-MRSA) strains in their nares over time. CONCLUSIONS: The findings of this study provides added perspective on the nasal carriage dynamics between strains colonizing persistent and intermittent carriers; an area currently in need of assessment given that persistent carriers are at greater risk of autoinfection than intermittent carriers.

The weekend effect does not influence management of inflammatory bowel disease.

BACKGROUND: The weekend effect describes worsened outcomes due to perceived inefficiency occurring over the weekend. This effect has not been studied in inflammatory bowel disease (IBD) despite increasing prevalence in the community. Therefore, our aim is to assess differences in the outcomes of weekend versus weekday management of IBD exacerbations. METHODS: The National Inpatient Sample database comprises approximately 20% of admissions to nonfederal hospitals in the United States. Complications requiring hospitalization ("flares") were the criteria upon which patient selection was based. A total of 193, 848 flares were identified from 2008 to 2014 using the International Classification of Diseases 9th edition codes. Differences in time to first procedure, length of stay (LOS), and cost were evaluated for patients with flares between weekend and weekday admissions. RESULTS: The time to first procedure was 3.33 days on weekends versus 3.19 days on weekdays (P < 0.001). The mean LOS was shorter when admissions occurred on weekends versus weekdays (8.01 days vs 8.22 days, P < 0.001). Finally, the cost of hospitalization was higher for weekday admissions versus weekend admissions ($18 072 vs $17 495, P < 0.001). CONCLUSION: Our results showed a similar LOS and cost associated with the management of exacerbations on the weekend compared to weekdays. While many high-risk conditions exhibit increased mortality and prolonged hospital course over the weekend, this phenomenon does not appear to affect IBD. These findings indicate efficient patient care on the weekend and can be utilized for logistical purposes such as resource allocation and procedure scheduling in the endoscopy suite.

Management and Treatment of Hepatocellular Carcinoma with Immunotherapy: A Review of Current and Future Options.

With mortality rates of liver cancer doubling in the last 20 years, this disease is on the rise and has become the fifth most common cancer in men and the seventh most common cancer in women. Hepatocellular carcinoma (HCC) represents approximately 90% of all primary liver cancers and is a major global health concern. Patients with HCC can be managed curatively with surgical resection or with liver transplantation, if they are diagnosed at an early stage. Unfortunately, most patients with HCC present with advanced stages of the disease and have underlying liver dysfunction, which allows only 15% of patients to be eligible for curative treatment. Several different treatment modalities are available, including locoregional therapy radiofrequency ablation, microwave ablation, percutaneous ethanol injection, trans-arterial chemoembolization, transarterial radio-embolization, cryoablation, radiation therapy, stereotactic radiotherapy, systemic chemotherapy, molecularly targeted therapies, and immunotherapy. Immunotherapy has recently become a promising method for inhibiting HCC tumor progression, recurrence, and metastasis. The term "Immunotherapy" is a catch-all, encompassing a wide range of applications and targets, including HCC vaccines, adoptive cell therapy, immune checkpoint inhibitors, and use of oncolytic viruses to treat HCC. Immunotherapy in HCC is a relatively safe option for treating patients with advanced disease in the USA who are either unable to receive or failed sorafenib/lenvatinib therapy and thus may offer an additional survival benefit for these patients. The purpose of this review is to elaborate on some of the most recent advancements in immunotherapy.

A comparison of diverticulitis in Crohn's disease versus ulcerative colitis.

BACKGROUND AND AIM: Inflammatory bowel disease (IBD) and diverticulitis both increase morbidity, especially when associated with in-patient hospitalization. This study aimed to evaluate whether hospitalization burden differs for diverticulitis in patients with a history of Crohn's disease (CD) compared to ulcerative colitis (UC). METHOD: All patients hospitalized for acute diverticulitis with pre-existing UC or CD in 2014 were selected using the national in-patient sample. Cases were identified using the International Classification of Diseases, Ninth Edition codes. Primary outcomes were mortality, cost of admission, length of stay (LOS), and colectomy. RESULTS: A total of 1815 patients were admitted with diverticulitis, and those with CD had a hospitalization associated with decreased cost (aOR -14 537, 95% CI -27 316 to -1758; P = 0.026) and LOS (aOR -1.31, 95% CI -2.41 to -0.208; P = 0.02) compared to UC. A second analysis comparing diverticulitis hospitalization between those with CD and those with the absence of IBD showed no significant difference in mortality (aOR 2.47, 95% CI 0.59 to 10.36; P = 0.22), LOS (aOR 0.03, 95% CI -0.47 to 0.54; P = 0.92), or cost of admission (aOR -2196, 95% CI -6933 to 2539; P = 0.36) between the cohorts. CONCLUSION: Patients with UC have worsened hospitalization outcomes when being treated for diverticulitis compared to CD. While the findings may be a result of a difference in colectomy rates, the etiology may also be multifactorial. These conclusions have not been previously described, and further investigations would better characterize these associations.

Association of Autoimmune Hepatitis and Cardiovascular Disease.

BACKGROUND: Autoimmune Hepatitis is a chronic liver disease while Cardiovascular Disease is seen in inflammatory states. This study sought to determine if Cardiovascular Disease was associated with Autoimmune Hepatitis. METHODS: The National Inpatient Sample selected patients with a primary diagnosis of Autoimmune Hepatitis and secondary diagnosis of Cardiovascular Disease in 2014. The primary outcome was the association of Autoimmune Hepatitis with Cardiovascular Disease. Secondary outcomes evaluated the hospital burden with Cardiovascular Disease. RESULTS: 16,375 patients with Autoimmune Hepatitis were included in the study. There was a decreased association between Autoimmune Hepatitis and Cardiovascular Disease (aOR 0.77, 95% CI 0.69-0.85, p < 0.00), Coronary Artery Disease, (aOR 0.75, 95% CI 0.67-0.85, p < 0.00), and Peripheral Vascular Disease (aOR 0.75, 95% CI 0.60-0.93, p = 0.01). Moreover, Coronary Artery Disease comprises 84% of the overall Cardiovascular Disease cohort and did not demonstrate significantly increased length of stay (aOR -0.53, 95% CI -1.16 to 0.12, p = 0.11) or hospitalization cost (aOR -6711, 95% CI -14336 to 912, p = 0.08). DISCUSSION: The decreased association between Autoimmune Hepatitis and Cardiovascular Disease is likely multifactorial in etiology. Consequently, this observation requires further examination with prospective trials.

The Association of leptin with severity of non-alcoholic fatty liver disease: A population-based study.

BACKGROUND/AIMS: Leptin is associated with metabolic disorders, which predispose one to non-alcoholic fatty liver disease (NAFLD). The role of leptin in NAFLD pathogenesis is not fully understood. We aim to investigate the association between serum leptin level and severity of NAFLD using U.S. nationally representative data. METHODS: Data were obtained from the United States Third National Health and Nutrition Examination Survey. NAFLD was defined by ultrasound detection and severity of hepatic steatosis in the absence of other liver diseases. The severity of hepatic fibrosis was determined by NAFLD fibrosis score (NFS). We used multivariate survey-weighted generalized logistic regression to evaluate the association between leptin level and the degree of NAFLD. We also performed subgroup analyses by body mass index (lean vs. classic NAFLD). RESULTS: Among 4,571 people, 1,610 (35%) had NAFLD. By ultrasound findings, there were 621 people with mild, 664 with moderate, and 325 with severe steatosis. There were 885 people with low NFS (<-1.455, no significant fibrosis), 596 with intermediate NFS, and 129 with high NFS (>0.676, advanced fibrosis). Leptin levels for normal, mild, moderate and severe steatosis were 10.7±0.3 ng/mL, 12.1±0.7 ng/mL, 15.6±0.8 ng/mL, 16±1.0 ng/mL, respectively (trend P-value<0.001). Leptin levels for low, intermediate, and high NFS were 11.8±0.5 ng/mL, 15.6±0.8 ng/mL, 28.5±3.5ng/mL, respectively (trend P-value<0.001). This association remained significant even after adjusting for known demographic and metabolic risk factors. In the subgroup analysis, this association was only prominent in classic NAFLD, but not in lean NAFLD. CONCLUSION: Serum leptin level is associated with the severity of NAFLD, especially in classic NAFLD patients.
