RHEMITT Score Predicts Rebleed After Capsule Endoscopy: First Validation at a U.S. Tertiary Care Center.

BACKGROUND: Patients with obscure gastrointestinal bleeding undergo small bowel capsule endoscopy (SBCE), but often return for recurrent bleeding or anemia. The RHEMITT score evaluates patients based on 7 variables (heart failure, chronic kidney disease, Saurin P1/P2 lesions, major bleeding, incomplete SBCE, smoking status, and endoscopic treatment) and seeks to predict the risk of rebleeding. AIMS: This study aims to perform an external validation of the RHEMITT score in the United States. METHODS: SBCEs performed to evaluate anemia or GI bleeding from a tertiary-care center's PillCam database between 1/22/2018 and 7/21/2020 were reviewed. Variables based on the RHEMITT score were collected. The primary outcome was rebleeding, defined as (1) melena or hematochezia or (2) hemoglobin drop of 2 g/dL. Patient were categorized into low, intermediate, and high-risk categories based on RHEMITT score. The accuracy of the RHEMITT score for predicting rebleeding was assessed. RESULTS: A total of 361 SBCEs were included in the study. Age, indication for SBCE, endoscopic treatment, antiplatelet use, cirrhosis, heart failure, chronic kidney disease, and major bleeding were significantly associated with risk of rebleed (p < 0.05). Each increasing risk category for the RHEMITT score predicted increased probability of this study's primary outcome, rebleeding (p < 0.001). There was a significant association between RHEMITT risk category and rebleeding-free survival (log-rank p < 0.001). An area under the receiver operating characteristic curve for the RHEMITT score was 0.790 (p < 0.001). CONCLUSION: Our findings validate the RHEMITT score and confirm acceptable performance for predicting rebleeding at a tertiary referral center in the United States.

The Safety of the Re-Opening of an Academic Medical Center Outpatient Endoscopy Unit During the COVID-19 Pandemic.

Background: The coronavirus disease 2019 (COVID-19) pandemic has spread globally leading to over 3,700,000 deaths. As COVID-19 cases stabilized, the re-opening of endoscopy centers potentially exposed patients and healthcare workers to viral infection. This study aims to determine risk of COVID-19 exposure among patients undergoing outpatient endoscopies in a tertiary care setting during the COVID-19 pandemic. Methods: Patients undergoing outpatient endoscopy were contacted post-procedure for any new COVID-19 symptoms or COVID-19 test results. Patient experiences and perception of personal safety were also determined. Results: Of the 1,584 patients who completed elective endoscopy, 996 (62.9%) completed the survey. Two patients were diagnosed with COVID-19 within 14 days of procedure. The majority (99.7%) felt safe during their procedure and apprehension regarding endoscopy decreased over time. Conclusion: Thus, the risk of COVID-19 transmission during outpatient endoscopy is extremely low when following recommended society guidelines. Patients felt safe during the procedure and experienced less fear of exposure over time.

Impact of Student-Run Clinics on Students' Attitudes Toward People Experiencing Homelessness.

INTRODUCTION: Student-run clinics can supplement medical education by exposing students to diverse clinical scenarios and collaborating with underresourced populations. We examined the impact of volunteering at THRIVE, a student-run bridge clinic located within sheltered housing for individuals with substance use disorder, on students' attitudes toward people experiencing homelessness (PEH). METHODS: This cohort study analyzed pre- and postsurvey matched responses from nonvolunteer and volunteer first-year medical students utilizing the Health Professional Attitudes Towards the Homeless (HPATHI) tool, totaled into three subcategories: Cynicism, Social Advocacy, and Personal Advocacy. We evaluated the association between change in scores and volunteering utilizing Student t tests and adjusting for participant characteristics using multivariable regression analysis. RESULTS: We received 106 responses (53% response rate); 58 students (55%) volunteered at the clinic and were mostly female (62%), White (52%), and had previous experience working with PEH (71%). The mean change in Personal Advocacy scores was higher for volunteers compared to nonvolunteers, even when adjusting for respondent characteristics (P=.02). Additionally, students who held a prior advanced degree and/or current enrollment in the master of bioethics program (Higher Education Students) had a positive association with change in Personal Advocacy scores (P=.02). CONCLUSION: Volunteering at the THRIVE Clinic appears to impact the Personal Advocacy scores of medical students. This suggests that interacting with PEH early in students' career may be associated with a commitment to working with this population. However, our study has multiple limitations, including self-selection bias, limited sample size, and unclear permanence of students' attitudes over time. Further studies of this cohort could help clarify the significance and permanence of volunteering in student-run clinics.

MAGIC versus MacDonald treatment regimens for gastric cancer: Trends and predictors of multimodal therapy for gastric cancer using the National Cancer Database.

BACKGROUND: Multimodal therapy is beneficial in gastric cancer, however this practice is not universal. This study examines trends, identifies associative factors, and examines overall survival (OS) benefit from multimodal therapy in gastric cancer. METHODS: Gastric cancer patients staged IB-III from 2005 to 2014, identified using the National Cancer Database, were categorized by treatment: surgery alone, perioperative chemotherapy, and adjuvant chemoradiation. Groups were analyzed to identify associative factors of perioperative therapy. RESULTS: We examined 9243 patients, with the majority receiving multimodal therapy (57%). The proportion of those receiving perioperative chemotherapy rose dramatically from 7.5% in 2006 to 46% in 2013. Academic center treatment was strongly associated with perioperative over adjuvant therapy (p < 0.0001). An OS advantage was clearly seen in those receiving multimodal therapy versus surgery alone (p < 0.0001), with no difference between perioperative and adjuvant therapies. CONCLUSIONS: Treatment of gastric cancer with multimodal therapy has risen significantly since 2005, largely due to increasing use of perioperative chemotherapy. As perioperative therapy becomes more prevalent, more patients will have the opportunity for the improved survival benefit of multimodal therapy.

The Effect of Sarcopenia on Outcomes in Geriatric Blunt Trauma.

Elderly patients are at a higher risk of morbidity and mortality after trauma, which is reflected through higher frailty indices. Data collection using existing frailty indices is often not possible because of brain injury, dementia, or inability to communicate with the patient. Sarcopenia is a reliable objective measure for frailty that can be readily assessed in CT imaging. In this study, we aimed to evaluate the effect of sarcopenia on the outcomes of geriatric blunt trauma patients. Left psoas area (LPA) was measured at the level of the third lumbar vertebra on the axial CT images. LPA was normalized for height (LPA mm2/m2) and after stratification by gender, sarcopenia was defined as LPA measurements in the lowest quartile. A total of 1175 patients consisting of 597 males and 578 females were studied. LPAs below 242.6 mm2/m2 in males and below 187.8 mm2/m2 in females were considered to be sarcopenic. We found sarcopenia in 149 males and 145 females. In multivariate analysis, sarcopenia was associated with a higher risk of in-hospital mortality (odds ratio [OR]: 1.61, 95% confidence interval [CI]: 1.01-2.56) and a higher risk of discharge to less favorable destinations (OR: 1.42, 95% CI: 1.05-1.97). Lastly, sarcopenic patients had an increased risk of prolonged hospitalization (hazard ratio: 1.21, 95% CI: 1.04-1.40).
