Background: Microscopic colitis (MC) causes chronic diarrhea. It has two histologic subtypes: lymphocytic colitis (LC) and collagenous colitis (CC). Little is known about the natural progression of disease with time and with treatment. Objectives: We aimed to assess histological changes over time. Design: We designed a retrospective study including adults diagnosed with MC from January 1992 to January 2020 at Mayo Clinic. Methods: Pathology reports were reviewed until 31 October 2020. Histological assessments at least 8 weeks apart were considered as adequate follow-up. Histological change from one subtype to the other and resolution were tracked with univariate and multivariable Cox proportional hazards models. Results: Overall, 416 patients with a median age at diagnosis of 63.9 years with >1 histopathological assessment were identified. Histology at initial diagnosis was CC in 218 (52.4%) patients and LC in 198 (47.6%). No medications were associated with a histological change. However, histological resolution was more likely with the use of aspirin [hazard ratio (HR): 2.10, 95% confidence interval (CI): 1.34–3.31, p = 0.001) and proton-pump inhibitors (PPIs; HR: 2.01, 95% CI: 1.34–3.02, p = 0.001). Histological resolution was more likely with budesonide treatment (HR: 1.86, 95% CI: 1.16–3.00, p = 0.010) and less likely with mesalamine (HR: 0.40, 95% CI: 0.19–0.83, p = 0.014), compared to medications such as prednisone, loperamide, and bismuth. Patients with CC were less likely to change their histology compared to patients with LC (HR: 0.24, 95% CI: 0.14–0.42, p < 0.001). There was no difference in histological resolution between the two subtypes (HR: 0.70, 95% CI: 0.47–1.05, p = 0.084). Conclusion: Patients with LC have a higher chance of changing their histology as compared to CC. However, histological resolution was associated with the use of PPIs and aspirin, and treatment with budesonide.

Introduction: Today’s physicians must demonstrate both professionalism and leadership skills in order to succeed in largely team-based healthcare environments. The purpose of this study was to determine if professionalism attributes, leadership style, and leadership style adaptability are associated with academic performance among first-year students early in their medical curriculum. Materials and Methods: Students were divided into 4-member dissection groups for the duration of the Gross and Developmental Anatomy course. Leadership responsibility was randomly assigned to a team member on a rotating basis every 5 weeks. After each 5-week block, student performance was measured by written and practical examinations, and each student assessed their leader’s or their own professionalism attributes and leadership style using validated survey instruments. Results: Most students demonstrated either a “selling” only (57%) or “participating” only (30%) leadership style with low to moderate leadership adaptability. “Participating” and “delegating” leadership styles have the highest average group written exam scores (89.4%, P <0.008). “Telling” only or “selling” only leaders have the lowest average group exam scores (83.5%, P <0.001). “Selling” and “participating” leaders have significantly lower average group practical exam scores than other styles (81.5%, P <0.007). Positive associations were observed between the written and practical examination scores and the leader’s integrity (P = 0.003, P = 0.002) and responsibility (P <0.001 , P = 0.037). Conclusions: This study demonstrates that various situational leadership styles and aspects of professionalism are associated with written and practical examination scores in the Gross and Developmental Anatomy course. Furthermore, it demonstrates that first-year medical students are in need of leadership skill development.

Background Sexual assault survivors are at increased risk for sexually transmitted infections. Sexual Assault Nurse Examiner programs guide sexually transmitted infection treatment, monitoring, and follow-up scheduling according to guidelines by the Centers for Disease Control and Prevention (CDC). Reported low rates of provider adherence to CDC treatment guidelines and patient adherence to follow-up necessitate a review of medication prescribing and follow-up scheduling practices, especially at smaller community hospitals in the United States. Methods A retrospective medical record review was conducted to assess adherence rates to CDC guidelines for prescribing practices, scheduling, and follow-up of sexual assault survivors. We included pediatric and adult patients presenting to the emergency department (ED) and participating in the ED Sexual Assault Nurse Examiner program at a rural, community-based teaching hospital in La Crosse, WI, from January 2018 to December 2021. Descriptive statistics were used to evaluate results. Results Analysis included 103 patients. Prescribing adherence to CDC guidelines was >80% for all except human immunodeficiency virus (53.4%), trichomoniasis (68.1%), and hepatitis B (69%). Of the 38 patients who had a follow-up scheduled during their ED encounter, 78.9% attended their scheduled follow-up and 94.7% of those appointments were scheduled within the CDC-recommended time frame, leading to an overall adherence of 40%. Conclusions Adherence rates were high for most prescribing practices, and attendance of scheduled follow-up was higher than expected. Opportunities to improved adherence to CDC guidelines were identified in prescribing for 3 disease states (human immunodeficiency virus, trichomoniasis, and hepatitis B) and in scheduling of follow-up.

Abstract Background Sexual assault survivors are at increased risk for sexually transmitted infections. Due to patient vulnerability, institutions have implemented Sexual Assault Nurse Examiner (SANE) protocols to care for these patients. These protocols guide evidence collection, testing, treatment, and medical follow-up to ensure optimization of sexually transmitted infections (STIs) treatment, monitoring and follow-up. Previous gap analyses have identified decreased prescribing of prophylactic STI medications and scheduling follow-up appointments compared to guideline recommendations. The purpose of this study was to assess adherence of medication prescribing and follow-up scheduling practices to Centers for Disease Control (CDC) guidelines. Methods This study was a single-center, retrospective, observational, descriptive assessment which evaluated adherence rates to CDC guidelines, to scheduling medical follow-up, and patient attendance at scheduled appointments. Pediatric and adult patients who presented to the emergency department at Mayo Clinic Health System in La Crosse, WI from January 2018 through December 2021 were included. Data collected through chart review included demographics and laboratory data necessary for prescribing prophylactic HIV medications, antibiotics for STIs, emergency contraception, and vaccine administration. Descriptive statistics were used to evaluate results. Results One hundred three patients were evaluated. Majority of patients were female and presented within 3 days of assault. Medication adherence to CDC guidelines was ≥ 80% for chlamydia and gonorrhea whereas &lt; 80% was noted for trichomoniasis and HIV prophylaxis. Adherence to post-ED discharge follow-up was 40%. Conclusion Opportunities to improve adherence of ED-SANE protocols for medication prescribing and medical follow-up for trichomoniasis and HIV prophylaxis exist.

11016 Background: Stress Management and Resiliency Training (SMART) is a validated resilience training program designed to reduce stress, improve emotional resilience, and decrease burnout. The prevalence of burnout among practicing oncologists is as high as 40%, but unknown among oncology trainees. We implemented a virtual format of the SMART program to the Hematology/Oncology fellowship at Mayo Clinic to assess the feasibility of such a delivery, measure baseline rates of burnout in this group, and to investigate if a virtual method of delivery is as effective as in-person delivery as described in the literature. Methods: The SMART project was a mixed-methods, prospective, single arm clinical trial. Hematology/Oncology Fellows at Mayo Clinic were invited to participate. Four one-hour training sessions were conducted virtually. Fellows were given access to SMART online video modules and a book which supported the content covered during virtual training, a companion resilience mobile app, and a paperback mindfulness journal. Stress, burnout, and emotional resilience were measured at baseline and three months post-intervention using the Perceived Stress Scale (PSS), Maslach Burnout Inventory (MBI), and Connor-Davidson Resilience Scale (CD-RISC2). Changes in mean scores on the PSS, MBI, and CD-RISC2 were assessed using the Wilcoxon signed-rank test. Program feedback and feasibility data were obtained during a virtual focus group. Audio transcripts from the focus group were codified for thematic analysis and verified by intercoder triangulation. A 6-month assessment will be due in March 2022. Results: 26 of 50 fellows invited participated in our study. At baseline, 24% of participants had measurable burnout and 92% had moderate to high stress. At 3-months, the number of participants with moderate to high stress decreased to 71%, while rates of burnout remained unchanged. The PSS demonstrated a decrease in mean stress (-10.9%, p = 0.005), while the MBI demonstrated decreased emotional exhaustion (MBI-EE -6.01%, p = 0.04), an improved sense of personal achievement (MBI-PA 28.1%, p < 0.001), but slightly worse feelings of depersonalization (MBI-DP 16.46%, p = 0.05). The CD-RISC2 suggested no change in global emotional resilience (-0.71%, p = 0.82). Thematic analysis of the focus group data revealed that participants overwhelmingly found the program beneficial (83% of all responses), 20% indicated improved stress, and 15% indicated improved work performance. Conclusions: Oncology fellows in this study had lower rates of burnout compared to practicing oncologists. Virtual implementation of the SMART program is feasible and resulted in improvements in stress and prevented worsened burnout. Outcomes were comparable to previously published studies conducted in-person. Focus group participants found the training beneficial, reported lower stress, and improved work performance.

Background and Aims: The impact of disease progression in NAFLD on liver outcomes remains poorly understood. We aimed to investigate NAFLD progression using longitudinal liver stiffness measurements (LSM) by serial magnetic resonance elastography (MRE) and the association with liver outcomes. Approach and Results: All adult patients with NAFLD who underwent at least two serial MREs for clinical evaluation at Mayo Clinic, Rochester, between 2007 and 2019 were identified from the institutional database. Progression and regression were defined based on LSM change of 19% above or below 19% of initial LSM, respectively, based on Quantitative Imaging Biomarker Alliance consensus. The association between change in LSM and liver‐related outcomes occurring after the last MRE was examined using time‐to‐event analysis. A total of 128 participants underwent serial MREs (53% female, median age 59 years). The median time between paired MREs was 3.4 (range 1–10.7) years. NAFLD progression (LSM = +0.61 kPa/year) was identified in 17 patients (13.3%). NAFLD regression (−0.40 kPa/year) occurred in 35 patients (27.3%). Stable LSM was noted in 76 participants (59.4%). In NAFLD without cirrhosis at baseline ( n = 75), cirrhosis development occurred in 14% of LSM progressors and 2.9% of non‐progressors ( p = 0.059) over a median 2.7 years of follow‐up from the last MRE. Among those with compensated cirrhosis at baseline MRE ( n = 29), decompensation or death occurred in 100% of LSM progressors and 19% of non‐progressors ( p < 0.001) over a median 2.5 years of follow‐up after the last MRE. Conclusions: Noninvasive monitoring of LSM by conventional MRE is a promising method of longitudinal NAFLD monitoring and risk estimation of liver‐related outcomes in NAFLD.

Abstract In clinical scenario surveys, inpatient providers were more likely to report continuing inappropriate (odds ratio, 2.02 [95% confidence interval, 1.35–3.03]; P&lt;.001) or broad-spectrum (1.8 [1.27–2.56]; P=.001) antibiotic therapy when initiated by emergency department providers, than to change to appropriate or narrow-spectrum therapy, respectively. Antibiotic inertia could represent a significant antibiotic stewardship target.

Abstract Background and Aims Although magnetic resonance elastography (MRE) has been well‐established for detecting and staging liver fibrosis, its prognostic role in determining outcomes of chronic liver disease (CLD) is mostly unknown. Approach and Results This retrospective study consisted of 1269 subjects who underwent MRE between 2007 and 2009 and followed up until death or last known clinical encounter or end of study period. Charts were reviewed for cirrhosis development, decompensation, and transplant or death. The cohort was split into baseline noncirrhosis (group 1), compensated cirrhosis (group 2), and decompensated cirrhosis (group 3). Cox‐regression analysis with age, sex, splenomegaly, CLD etiology, Child‐Pugh Score (CPS), Fibrosis‐4 Index (FIB‐4) score, and Model for End‐Stage Liver Disease (MELD)–adjusted HR for every 1‐kPa increase in liver stiffness measurement (LSM) were used to assess the predictive performance of MRE on outcomes. Group 1 ( n = 821) had baseline median LSM of 2.8 kPa, and cirrhosis developed in 72 (8.8%) subjects with an overall rate of about 1% cirrhosis/year. Baseline LSM predicted the future cirrhosis with multivariable adjusted HR of 2.38 ( p < 0.0001) (concordance, 0.84). In group 2 ( n = 277) with baseline median LSM of 5.7 kPa, 83 (30%) subjects developed decompensation. Baseline LSM predicted the future decompensation in cirrhosis with FIB‐4 and MELD‐adjusted HR of 1.22 ( p < 0.0001) (concordance, 0.75). In group 3 ( n = 171) with median baseline LSM of 6.8 kPa (5.2, 8.4), 113 (66%) subjects had either death or transplant. Baseline LSM predicted the future transplant or death with HR of 1.11 ( p = 0.013) (concordance 0.53) but not in CPS and MELD‐adjusted models ( p = 0.08). Conclusion MRE‐based LSM is independently predictive of development of future cirrhosis and decompensation, and has predictive value in future transplant/death in patients with CLD.
