BACKGROUND: Differentiating Takotsubo cardiomyopathy (TTC) from acute coronary syndrome involving the left anterior descending coronary artery (LAD-ACS) is difficult due to left ventricular apical wall motion abnormality pattern in both and typically requires an invasive coronary angiography (ICA) study for diagnostic confirmation. OBJECTIVES: To identify differences in the regional wall motion abnormality (RWMA) pattern using a comprehensive comparative analysis of the transthoracic echocardiographic (TTE) findings in patients with TTC versus LAD-ACS. METHODS: This was a retrospective, randomized, blinded comparison study including a derivation cohort of 105 patients with TTC (N=52) or LAD-ACS (N=53) with concomitant TTE and ICA identified from our institutional database. A comprehensive echocardiographic wall motion analysis was performed (unblinded) to search for subtle differences in RWMA patterns by marking the exact locations of the end-systolic hinge points (HP) - defined as the intersection between the normal and abnormal regional myocardial thickening - in all apical views. The HP location relative to mitral annulus in each apical view was compared for symmetry and the apical 2-chamber (A2C) view was identified as having the most consistent, quantitative difference between TTC and LAD-ACS. This A2C quantitative model was then prospectively studied in a randomized, blinded, validation cohort of 30 subjects with either TTC or LAD-ACS by eight echocardiographic readers with all levels of clinical experience. RESULTS: In the unblinded derivation cohort, the A2C view showed that the ratio (1.02) and the absolute distance between the anterior HP (3.57 cm) and the inferior HP (3.53 cm) in TTC was significantly different than the ratio (0.761) and the absolute differences between the AHP (4.5 cm) and the IHP (5.93 cm) in LAD-ACS. An AHP: IHP of 0.96 for men and 0.84 for women was able to correctly categorize 84.8% of male and 91.7% of female patients. When applied to the validation cohort, the model showed fairly accurate results with a 74% prediction rate in diagnosing TTC in female patients. CONCLUSION: We propose a relatively simple 2-D TTE diagnostic tool emphasizing subtle differences in the RWMA pattern in the A2C view alone as a semi-quantitative imaging parameter to help differentiate TTC from LAD-ACS.

BACKGROUND: The clinical demands for hospitalist groups have grown at academic medical centers, without similar growth of teaching opportunities for faculty. Traditional resident teaching teams are often crowded with learners which can limit acting intern (or subintern) patient encounters. Medical students are often placed on nonresident teaching teams, although there are few studies on learner experience on a nonresident teaching team model. METHODS: To address these concerns, we created two nonresident teaching teams composed of one attending and two acting interns. We compared acting intern experience on the nonresident teaching teams to the traditional resident teams to determine if there were significant differences in student experience by reviewing course evaluation data on the two team models. RESULTS: Of the 276 students who completed the Internal Medicine Acting Internship from 2019 to 2023, 224 students (81%) completed the course evaluation. The course was highly rated, and the ratings were similar in both models demonstrating that the nonresident teaching team model is an effective option for acting interns. CONCLUSION: The nonresident teaching team model can offload crowded teaching teams, add additional acting intern experiences, and add teaching opportunities for hospital medicine attendings.
RESUMO
OBJECTIVES: Medical school curricula have increasingly incorporated topics and content related to health equity and affiliated social determinants of health. However, there is limited literature to guide how programs might measure the success of these initiatives. Previous studies assessed medical student attitudes and perceived knowledge, preparedness, and skills. Based on self-reported measures of these attributes, we compared within-group and between-group differences at the onset of a novel equity-focused curriculum implementation. METHODS: A multi-component approach to "thread" lectures, panel discussions, and other content dedicated to health equity concepts was assessed using adapted versions of two validated survey instruments of the measured constructs. Baseline data were collected prior to coursework and at follow-up early in students' second year assessed change attributable to the equity-focused curriculum thread, with additional comparison to a cohort of second-year students who had no exposure to the curriculum. Data were collected at the beginning of academic years 2021-2022 and 2022-2023. RESULTS: The multivariate analysis of variance indicated significant change over time (p < 0.001) with the analyses of variance identifying students' perceived current skills and topic knowledge increasing over time. No significant differences were found between two separate groups of M2 students. CONCLUSIONS: Students' perceived skills at working with diverse patient populations and knowledge of topics focused on health equity increased across the study, despite a much smaller response rate for the same student cohort at follow-up. Students' perception that they are prepared to care for patients of diverse backgrounds was unaffected. Attitudinal assessment revealed a ceiling effect at baseline, which should be explored further with longitudinal assessment. For the ongoing effort to evaluate the success of equity-focused curricula and programs, this study contributes evidence of change on some but not all outcomes, and can help guide other programs in determining which outcomes best reflect areas of programmatic need and impact.
RESUMO
BACKGROUND: Kentucky was among the first to adopt Medicaid expansion, resulting in reducing uninsured rates from 14.3% to 6.4%. We hypothesize that Medicaid expansion resulted in increased elective healthcare utilization and reductions in emergency treatments by patients suffering Inflammatory Bowel Disease (IBD). METHODS: The Hospital Inpatient Discharge and Outpatient Services Database (HIDOSD) identified all encounters related to IBD from 2009 to 2020 in Kentucky. Several demographic variables were compared in pre- and post-Medicaid expansion adoption. RESULTS: Our study analyzed 3386 pre-expansion and 24,255 post-expansion encounters for IBD patients. Results showed that hospitalization rates dropped (47.7%-8.4%), outpatient visits increased (52.3%-91.6%) and Emergency visits decreased (36.7%-11.4%). Admission following a clinical referral similarly increased with a corresponding drop in emergency room admissions. Hospital costs and lengths of stay also dropped following Medicaid expansion. CONCLUSION: In the IBD population, Medicaid expansion improved access to preventative care, reduced hospital costs by decreasing emergency care, and increased elective care pathways.

INTRODUCTION: Hospitalizations due to severe injection-related infections (SIRIs) and patient-directed discharge (PDD) in people who inject drugs (PWID) are increasing, but research on readmission outcomes at PDD is limited. In this retrospective, matched cohort study we evaluated predictors of 30-day readmission by discharge status among PWID. METHODS: Among patients diagnosed with SIRIs at a tertiary hospital, Fisher's exact tests assessed differences in readmission rates by discharge status. Medications for opioid use disorder (MOUD) at discharge was defined as either having a buprenorphine dose dispensed within 24 h of discharge and buprenorphine being included in the discharge summary as a prescription, or a methadone dose dispensed inpatient within 24 h of discharge. Logistic regression analyses evaluated predictors of readmission outcomes. RESULTS: Among 148 PWID with SIRI diagnosis, 30-day readmission rate following PDD was higher than standard discharge (25.7 % vs. 9.5 %, p = 0.016) and MOUD decreased odds of 30-day readmission (OR = 0.32, 95 % CI: 0.12,0.83, p = 0.012). >7 missed days of antibiotic treatment increased odds of 30-day readmission (OR 4.65, 95 % CI: 1.14, 31.72, p = 0.030) within PDD patients. CONCLUSIONS: PDD carries higher 30-day readmission rate compared to standard discharge. Strategies to reduce PDD rates and increase MOUD initiation may improve readmission outcomes.

This study seeks to compare fixed and mixed effects models for the purposes of predictive classification in the presence of multilevel data. The first part of the study utilizes a Monte Carlo simulation to compare fixed and mixed effects logistic regression and random forests. An applied examination of the prediction of student retention in the public-use U.S. PISA data set was considered to verify the simulation findings. Results of this study indicate fixed effects models performed comparably with mixed effects models across both the simulation and PISA examinations. Results broadly suggest that researchers should be cognizant of the type of predictors and data structure being used, as these factors carried more weight than did the model type.
RESUMO
BACKGROUND: Medicaid expansion improved insurance coverage for patients with chronic conditions and low income. The effect of Medicaid expansion on patients with IBD from high-poverty communities is unknown. OBJECTIVE: This study aimed to evaluate the impact of Medicaid expansion in Kentucky on care for patients with IBD from the Eastern Kentucky Appalachian community, a historically impoverished area. DESIGN: This study was a retrospective, descriptive, and ecological study. SETTINGS: This study was conducted in Kentucky using the Hospital Inpatient Discharge and Outpatient Services Database. PATIENTS: All encounters for IBD care for 2009-2020 for patients from the Eastern Kentucky Appalachian region were included. MAIN OUTCOME MEASURES: The primary outcomes measured were proportions of inpatient and emergency encounters, total hospital charge, and hospital length of stay. RESULTS: Eight hundred twenty-five preexpansion and 5726 postexpansion encounters were identified. Postexpansion demonstrated decreases in the uninsured (9.2%-1.0%; p < 0.001), inpatient encounters (42.7%-8.1%; p < 0.001), emergency admissions (36.7%-12.3%; p < 0.001), admissions from the emergency department (8.0%-0.2%; p < 0.001), median total hospital charge ($7080-$3260; p < 0.001), and median total hospital length of stay (4-3 days; p < 0.001). Similarly, postexpansion demonstrated increases in Medicaid coverage (18.8%-27.7%; p < 0.001), outpatient encounters (57.3%-91.9%; p < 0.001), elective admissions (46.9%-76.2%; p < 0.001), admissions from the clinic (78.4%-90.2%; p < 0.001), and discharges to home (43.8%-88.2%; p < 0.001). LIMITATIONS: This study is subject to the limitations inherent in being retrospective and using a partially de-identified database. CONCLUSION: This study is the first to demonstrate the changes in trends in care after Medicaid expansion for patients with IBD in the Commonwealth of Kentucky, especially Appalachian Kentucky, showing significantly increased outpatient care utilization, reduced emergency department encounters, and decreased length of stays.

BACKGROUND: Additional therapies for hepatic encephalopathy (HE) treatment are warranted. There are data evaluating the use of zinc for HE; however, clinical outcomes, specifically in the United States, are unknown. OBJECTIVE: To compare 30-day and 1-year all-cause readmission rates in patients with cirrhosis complicated by HE on lactulose and rifaximin to those on lactulose, rifaximin, and zinc. METHODS: This retrospective study included patients admitted with documented cirrhosis and home medications of lactulose and rifaximin, with or without zinc. Patients were stratified into 2 groups: those receiving lactulose and rifaximin for HE (control) and those receiving lactulose, rifaximin, and zinc for HE (treatment). The primary outcomes were 30-day and 1-year all-cause readmission rates. RESULTS: One-hundred fifty-seven patients were included (102 in control group, 55 in treatment group). Regarding 30-day and 1-year all-cause readmission rates, there was no difference between the control and treatment groups. CONCLUSION AND RELEVANCE: This is the first study conducted in the United States evaluating zinc for HE treatment. Zinc did not impact 30-day or 1-year all-cause readmission rates. Further studies are warranted to evaluate the potential benefit of zinc for HE, possibly in correlation with Model for End-stage Liver Disease-Sodium (MELD-Na) scores.

This study provides a rigorous assessment of a community-based early child development (ECD) intervention to understand the drivers of caregivers' reading and playing practices in a low-resourced township in South Africa. Mentors visited 157 homes biweekly (2474 observations from 2019-21; children ages 0-5), completing surveys regarding caregiver behaviors and engagement. One hundred and fifty-seven caregivers (mostly Black, Zulu women) participated in the program during this time period and completed surveys biannually on their support system (modified version of the Multidimensional Scale of Perceived Support) and ECD beliefs (modified versions of the Parental Play Beliefs Scale and the Parent Opinion Survey). Longitudinal Hierarchical Linear Model revealed that several behaviors and beliefs significantly predicted positive parenting behaviors. Regression discontinuity plots suggest that positive parenting behaviors could continue and even improve following Covid-19 shutdowns, especially in homes with more intervention visits. This paper provides translational evidence on tangible ways interventions can engage caregivers in stimulating ECD behaviors.
RESUMO
Oftentimes in many fields of the social and natural sciences, data are obtained within a nested structure (e.g., students within schools). To effectively analyze data with such a structure, multilevel models are frequently employed. The present study utilizes a Monte Carlo simulation to compare several novel multilevel classification algorithms across several varied data conditions for the purpose of prediction. Among these models, the panel neural network and Bayesian generalized mixed effects model (multilevel Bayes) consistently yielded the highest prediction accuracy in test data across nearly all data conditions.
RESUMO
During adolescence, individuals make judgements on the legitimacy of authorities to make and enforce rules and they differentiate between various types of rules. This study tracked a socially and racially diverse sample (47% White) of 800 Brazilians for three years, ages 11-13 (50% female), allowing for variation between issues and individuals. The strongest predictors of compliance were adolescents' beliefs that parents were legitimate authorities. Other significant predictors were authorities' procedural justice and disciplinary practices. Legitimacy attributions partially mediated the relationship between procedural justice and compliance. Compliance and legitimacy varied across issues. Across time, parenting variables diminished in predictive strength while legitimacy attributions increased. Procedural justice practices may partially establish parental legitimacy, while disciplinary practices are less effective and perhaps counter-productive.
