Identifying and addressing patients' social health are essential to addressing health equity. Screening for social needs and connecting patients to resources in clinical settings is one way to identify and address the social factors that contribute to health. Policy makers are increasingly turning to incentivizing and requiring social needs screening and referrals to encourage health systems to identify and address patient social needs. NYC Health + Hospitals implemented and scaled social needs screening and referrals starting in 2017 across primary care clinical sites. The health system's approach was to focus on screening for patients' highest-priority needs for which there were available resources, to prioritize effective screening and referrals over universal screening, and to establish referral workflows. Implementing meaningful social needs screening and referrals requires a significant investment in creating screening workflows and in building key resources to meet patient needs.

The human vaginal and fecal microbiota change during pregnancy. Because of the proximity of these perineal sites and the evolutionarily conserved maternal-to-neonatal transmission of the microbiota, we hypothesized that the microbiota of these two sites (rectal and vaginal) converge during the last gestational trimester as part of the preparation for parturition. To test this hypothesis, we analyzed 16S rRNA sequences from vaginal introitus and rectal samples in 41 women at gestational ages 6 and 8 months, and at 2 months post-partum. The results show that the human vaginal and rectal bacterial microbiota converged during the last gestational trimester and into the 2nd month after birth, with a significant decrease in Lactobacillus species in both sites, as alpha diversity progressively increased in the vagina and decreased in the rectum. The microbiota convergence of the maternal vaginal-anal sites perinatally might hold significance for the inter-generational transmission of the maternal microbiota.

Celiac disease (CD) is a chronic autoimmune disorder that affects the small intestine in genetically predisposed individuals. Previous studies have investigated the potential link between CD and cardiovascular disease (CVD); however, the findings have been inconsistent. We aimed to provide an updated review of the literature on the association between CD and CVD. PubMed was searched from inception to January 2023 using keywords including CD, cardiovascular disease, coronary artery disease, cardiac arrhythmia, heart failure, cardiomyopathy, and myocarditis. We summarized the results of the studies, including meta-analyses and original investigations, and presented them according to the different forms of CVD. Meta-analyses published in 2015 provided mixed results regarding the relationship between CD and CVD. However, subsequent original investigations have shed new light on this association. Recent studies indicate that individuals with CD are at a higher risk of developing overall CVD, including an increased risk of myocardial infarction and atrial fibrillation. However, the link between CD and stroke is less established. Further research is needed to determine the link between CD and other cardiac arrhythmias, such as ventricular arrhythmia. Moreover, the relationship between CD and cardiomyopathy or heart failure, as well as myopericarditis, remains ambiguous. CD patients have a lower prevalence of traditional cardiac risk factors, such as smoking, hypertension, hyperlipidemia, and obesity. Therefore, it is important to discover strategies to identify patients at risk and reduce the risk of CVD in CD populations. Lastly, it is unclear whether adherence to a gluten-free diet can diminish or increase the risk of CVD among individuals with CD, necessitating further research in this area. To fully comprehend the correlation between CD and CVD and to determine the optimal prevention strategies for CVD in individuals with CD, additional research is necessary.

PURPOSE/UNASSIGNED:With undergraduate medical education shifting to an integrated, student-centered approach, self-regulated learning (SRL) skills are critical for student success. Educational research holds that learning strategy effectiveness is context dependent. Our study aims to explore what strategies medical students use to support SRL when engaged in the specific context of an integrated, student-centered curriculum. APPROACH/UNASSIGNED:This study took place in two medical schools with integrated, student-centered curricula. Semi-structured interviews were conducted with first-year medical students from both schools, asking them to reflect on the learning strategies they used throughout their first year of medical school. Interview data was analyzed first deductively using the SRL framework and then inductively to understand the specific strategies being used. FINDINGS/UNASSIGNED:Students engaged in strategies to support SRL in ways that were unique to the integrated, student-centered context. We found that medical students developed strategies to plan for integration and building connections across material during all three phases of self-regulated learning. INSIGHTS/UNASSIGNED:By identifying specific tasks and behaviors students utilized during their first year of medical school, this study provides a roadmap that students and educators can use to help students become self-regulated learners.

BACKGROUND:AKI is a heterogeneous syndrome. Current subphenotyping approaches have only used limited laboratory data to understand a much more complex condition. METHODS:We focused on patients with AKI from the Assessment, Serial Evaluation, and Subsequent Sequelae in AKI (ASSESS-AKI). We used hierarchical clustering with Ward linkage on biomarkers of inflammation, injury, and repair/health. We then evaluated clinical differences between subphenotypes and examined their associations with cardiorenal events and death using Cox proportional hazard models. RESULTS:We included 748 patients with AKI: 543 (73%) of them had AKI stage 1, 112 (15%) had AKI stage 2, and 93 (12%) had AKI stage 3. The mean age (±SD) was 64 (13) years; 508 (68%) were men; and the median follow-up was 4.7 (Q1: 2.9, Q3: 5.7) years. Patients with AKI subphenotype 1 ( N =181) had the highest kidney injury molecule (KIM-1) and troponin T levels. Subphenotype 2 ( N =250) had the highest levels of uromodulin. AKI subphenotype 3 ( N =159) comprised patients with markedly high pro-brain natriuretic peptide and plasma tumor necrosis factor receptor-1 and -2 and low concentrations of KIM-1 and neutrophil gelatinase-associated lipocalin. Finally, patients with subphenotype 4 ( N =158) predominantly had sepsis-AKI and the highest levels of vascular/kidney inflammation (YKL-40, MCP-1) and injury (neutrophil gelatinase-associated lipocalin, KIM-1). AKI subphenotypes 3 and 4 were independently associated with a higher risk of death compared with subphenotype 2 and had adjusted hazard ratios of 2.9 (95% confidence interval, 1.8 to 4.6) and 1.6 (95% confidence interval, 1.01 to 2.6, P = 0.04), respectively. Subphenotype 3 was also independently associated with a three-fold risk of CKD and cardiovascular events. CONCLUSIONS:We discovered four AKI subphenotypes with differing clinical features and biomarker profiles that are associated with longitudinal clinical outcomes.

We sought to understand the current state of research in adult Hospital Medicine by repeating a 2018 survey of leaders in Hospital Medicine with changes to improve the response rate of surveyed programs. We also analyzed the public sources of federal research funding and MEDLINE-indexed publications from 2010 through 2019 among members of the Society of Hospital Medicine (SHM). Of the 102 contacted leaders of Hospital Medicine groups across the country, 49 responded, for a total response rate of 48%. Among the 3397 faculty members represented in responding programs, 72 (2%) of faculty were identified as conducting research for more than 50% of their time. Respondents noted difficulties at every stage of the research development pipeline, from a lack of mentors to running a fellowship program to a lack of applicants seeking further research training. Improvements to our research training pipeline will be essential to the long-term improvement of our profession.

The coronavirus disease 2019 (COVID-19) pandemic has caused more than 675 million confirmed cases and nearly 7 million deaths worldwide [1]. While testing for COVID-19 was initially centered in health care facilities, with required reporting to health departments, it is increasingly being performed in the home with rapid antigen testing [2]. Most at-home tests are self-interpreted and not reported to a provider or health department, which could lead to delayed reporting or underreporting of cases [3]. As such, there is a strong possibility that reported cases may become a less reliable indicator of transmission over time.

Background Obesity and illicit drugs are independent risk factors for developing heart failure (HF). However, recent studies have suggested that patients who already have HF and are obese have better clinical outcomes. We aim to study the effect of cocaine use on this obesity paradox phenomenon as it pertains to HF readmissions. Methodology In a retrospective chart analysis, we reviewed patients with a diagnosis of HF with reduced ejection fraction (HFrEF) admitted to Metropolitan Hospital in New York. We studied the association between body mass index (BMI) categories, namely, non-obese (<30 kg/m²) and obese (≥30 kg/m²), cocaine use, and the primary outcome (time to readmission for HF within 30 days after discharge). The interaction between cocaine and obesity status and its association with the primary outcome was also assessed. Results A total of 261 patients were identified. Non-obese status and cocaine use were associated with an increased hazard of readmission in 30 days (hazard ratio (HR) = 2.28, p = 0.049 and HR = 3.12, p = 0.004, respectively). Furthermore, cocaine users who were non-obese were over six times more likely to be re-admitted in 30 days compared to non-cocaine users who were obese (HR = 6.45, p = 0.0002). Conclusions Non-obese status and continued use of cocaine have a negative additive effect in impacting HF readmissions.

BACKGROUND:While pharmacologic prophylaxis has benefits for venous thromboembolism (VTE) prevention in high-risk patients, unnecessary use carries potential harm, including bleeding, heparin-induced thrombocytopenia, and patient discomfort, and should be avoided in low-risk patients. While many quality improvement initiatives aim to reduce underuse, successful models on reducing overuse are sparse in the literature. OBJECTIVE:We aimed to create a quality improvement initiative to reduce overuse of pharmacologic VTE prophylaxis. DESIGNS, SETTINGS AND PARTICIPANTS/UNASSIGNED:A quality improvement initiative was implemented across 11 safety net hospitals in New York City. INTERVENTION/METHODS:The first electronic health record (EHR) intervention consisted of a VTE order panel that facilitated risk assessment and recommended VTE prophylaxis for high-risk patients only. The second EHR intervention used a best practice advisory that alerted clinicians when prophylaxis was ordered for a patient previously deemed "low risk." Prescribing rates were compared through a three-segment interrupted time series linear regression design. RESULTS:Compared to the preintervention period, the first intervention did not change the rate of total pharmacologic prophylaxis immediately after implementation (1.7% relative change, p = .38) or over time (slope difference of 0.20 orders per 1000 patient days, p = .08). Compared to the first intervention period, the second intervention led to an immediate 4.5% reduction in total pharmacologic prophylaxis (p = .04) but increased thereafter (slope difference of 0.24, p = .03) such that weekly rates at the end of the study were similar to rates prior to the second intervention.
