OBJECTIVE/UNASSIGNED:HbA1c is an insensitive marker for assessing real-time dysglycemia in obesity. This study investigated whether 1-h plasma glucose level (1-h PG) ≥155 mg/dL (8.6 mmol/L) during an oral glucose tolerance test (OGTT) and continuous glucose monitoring (CGM) measurement of glucose variability (GV) better reflected dysglycemia than HbA1c after weight loss from metabolic and bariatric surgery. METHODS/UNASSIGNED:This was a prospective cohort study of 10 participants with type 2 diabetes compared with 11 participants with non-diabetes undergoing sleeve gastrectomy (SG). At each research visit; before SG, and 6 weeks and 6 months post-SG, body weight, fasting lipid levels, and PG and insulin concentrations during an OGTT were analyzed. Mean amplitude of glycemic excursions (MAGE), a CGM-derived GV index, was analyzed. RESULTS/UNASSIGNED:-cell function, remained reduced in the diabetes group when compared to the non-diabetes group. CONCLUSIONS/UNASSIGNED:-cell dysfunction and the potential residual risk of diabetes complications.

OBJECTIVE:This pilot study compared a novel communication strategy, the positive approach to the psychiatric interview, with the traditional approach to see if the positive approach can be taught to psychiatric residents; reproduced with standardized patients; measured with a structured scale, the "Positive Approach Outcome Measure," by blinded raters; and used to improve rapport (assessed with the Bond score), a key driver of engagement. METHODS:Thirty psychiatric residents were randomly assigned to conduct two psychiatric interviews with standardized patients. The standardized patients completed the Working Alliance Inventory-Short Revised, an assessment of the therapeutic alliance. T tests and linear regression examined the effect of the training on the outcome of interest, the Bond score. RESULTS:The Bond scores for the positive approach group (M = 19.27, SD = 2.87) and the traditional approach group (M = 16.90, SD = 3.44) were statistically significantly different (p = 0.05). All residents trained in the positive approach received a positive score on the Positive Approach Outcome Measure while none of the traditional approach-trained residents attained the threshold. The inter-rater reliability for the blinded raters was high (0.857), as was the intra-rater reliability (1.0). CONCLUSIONS:The positive approach can be taught to residents and reproduced consistently and was associated with improvement in a key driver of treatment engagement: rapport. The positive approach may be an important, inexpensive intervention to improve treatment engagement and ultimately treatment outcomes.

BACKGROUND:Medical students' written reflections on their clinical experiences can be a useful tool for processing complex aspects of development as physicians. To create educational programs that scaffold adaptive professional identity development, it is essential to understand how medical students develop as professionals and process the dynamic sociocultural experiences of the current moment. OBJECTIVE:To explore the developing professional consciousness of medical students through clerkship reflections. DESIGN/METHODS:Narrative analysis of written reflections are produced by clerkship students, who were asked to tell a story that resonated with the physician's relationship with patient, self and colleagues. Two independent readers applied inductive labels to generate a homogenous codebook, which was used to generate themes that were then used to construct a conceptual model. KEY RESULTS/RESULTS:Four themes were identified in the data that describe relationships between medical students' developing professional identities and the norms of their future professional and personal communities. These included: medical students as outsiders, conflict between the student identifying with the patient versus the healthcare team, medical students' own value judgements and, finally, the changing societal mores as they relate to social and racial injustice. The conceptual model for this experience depicts the medical student as pulled between patients and the social context on one side and the professional context of the medical centre on the other. Students long to move towards identification with the healthcare team, but reject the extremes of medical culture that they view on conflict with social and racial justice. CONCLUSIONS:Medical students in clinical training identify strongly with both patients and the medical team. Rather than viewing professional identity development as a longitudinal journey from one extreme to another, students have the power to call attention to entrenched problems within medical culture and increase empathy for patients by retaining their strong identification with the important issues of this time.

BACKGROUND/UNASSIGNED:Identifying patients with the optimal risk:benefit for ticagrelor is challenging. The aim was to identify ticagrelor-responsive platelet transcripts as biomarkers of platelet function and cardiovascular risk. METHODS/UNASSIGNED:Healthy volunteers (n=58, discovery; n=49, validation) were exposed to 4 weeks of ticagrelor with platelet RNA data, platelet function, and self-reported bleeding measured pre-/post-ticagrelor. RNA sequencing was used to discover platelet genes affected by ticagrelor, and a subset of the most informative was summarized into a composite score and tested for validation. This score was further analyzed (1) in CD34+ megakaryocytes exposed to an P2Y12 inhibitor in vitro, (2) with baseline platelet function in healthy controls, (3) in peripheral artery disease patients (n=139) versus patient controls (n=30) without atherosclerosis, and (4) in patients with peripheral artery disease for correlation with atherosclerosis severity and risk of incident major adverse cardiovascular and limb events. RESULTS/UNASSIGNED:Ticagrelor exposure differentially expressed 3409 platelet transcripts. Of these, 111 were prioritized to calculate a Ticagrelor Exposure Signature score, which ticagrelor reproducibly increased in discovery and validation cohorts. Ticagrelor's effects on platelets transcripts positively correlated with effects of P2Y12 inhibition in primary megakaryocytes. In healthy controls, higher baseline scores correlated with lower baseline platelet function and with minor bleeding while receiving ticagrelor. In patients, lower scores independently associated with both the presence and extent of atherosclerosis and incident ischemic events. CONCLUSIONS/UNASSIGNED:Ticagrelor-responsive platelet transcripts are a biomarker for platelet function and cardiovascular risk and may have clinical utility for selecting patients with optimal risk:benefit for ticagrelor use.

Even with modern advancements in the management of acute mesenteric ischemia over the past decade, morbidity and mortality remain high, and the best primary treatment modality is still debated amongst interventionalists. Traditionally, interventionalists have favored an open surgical approach but are now trending for endovascular interventions due to apparent reduced mortality and complications. Newer studies suggest hybrid approaches, and intestinal stroke centers may be superior to either strategy alone. This narrative review will explore the natural history of acute mesenteric ischemia with the aim of increasing interventionalist awareness of modern advancements in revascularization strategies for this devastating disease.

Scientific misconduct is an issue rife with controversy, from its forms and definitions to the policies that guide how allegations are handled. A survey published nearly 15 years ago reported that 2% of researchers said they had fabricated or falsified data in their published work. This is not just an academic issue. Fake data promote ineffective or even dangerous treatments, for example, and thwart the discovery of real solutions for society. In the United States, the Office of Research Integrity (ORI) is tasked with rooting out misconduct in research funded by the National Institutes of Health (NIH). Last October, ORI proposed changes to how it functions. The agency's recommendations-the first since 2005-have evoked mixed reactions, but the real problem is that ORI is underfunded and lacks the resources and authority needed to make a difference. Unless its charter is revised by Congress, the ORI can sadly do little more than tinker at the edges of scientific fraud.

IMPORTANCE:Equity is an essential domain of health care quality. The Centers for Medicare & Medicaid Services (CMS) developed 2 Disparity Methods that together assess equity in clinical outcomes. OBJECTIVES:To define a measure of equitable readmissions; identify hospitals with equitable readmissions by insurance (dual eligible vs non-dual eligible) or patient race (Black vs White); and compare hospitals with and without equitable readmissions by hospital characteristics and performance on accountability measures (quality, cost, and value). DESIGN, SETTING, AND PARTICIPANTS:Cross-sectional study of US hospitals eligible for the CMS Hospital-Wide Readmission measure using Medicare data from July 2018 through June 2019. MAIN OUTCOMES AND MEASURES:We created a definition of equitable readmissions using CMS Disparity Methods, which evaluate hospitals on 2 methods: outcomes for populations at risk for disparities (across-hospital method); and disparities in care within hospitals' patient populations (within-a-single-hospital method). EXPOSURES:Hospital patient demographics; hospital characteristics; and 3 measures of hospital performance-quality, cost, and value (quality relative to cost). RESULTS:Of 4638 hospitals, 74% served a sufficient number of dual-eligible patients, and 42% served a sufficient number of Black patients to apply CMS Disparity Methods by insurance and race. Of eligible hospitals, 17% had equitable readmission rates by insurance and 30% by race. Hospitals with equitable readmissions by insurance or race cared for a lower percentage of Black patients (insurance, 1.9% [IQR, 0.2%-8.8%] vs 3.3% [IQR, 0.7%-10.8%], P < .01; race, 7.6% [IQR, 3.2%-16.6%] vs 9.3% [IQR, 4.0%-19.0%], P = .01), and differed from nonequitable hospitals in multiple domains (teaching status, geography, size; P < .01). In examining equity by insurance, hospitals with low costs were more likely to have equitable readmissions (odds ratio, 1.57 [95% CI, 1.38-1.77), and there was no relationship between quality and value, and equity. In examining equity by race, hospitals with high overall quality were more likely to have equitable readmissions (odds ratio, 1.14 [95% CI, 1.03-1.26]), and there was no relationship between cost and value, and equity. CONCLUSION AND RELEVANCE:A minority of hospitals achieved equitable readmissions. Notably, hospitals with equitable readmissions were characteristically different from those without. For example, hospitals with equitable readmissions served fewer Black patients, reinforcing the role of structural racism in hospital-level inequities. Implementation of an equitable readmission measure must consider unequal distribution of at-risk patients among hospitals.

UNLABELLED:Climate change is worsening with tangible effects on our healthcare system. This review aims to examine the repercussions of the climate change on nephrology and explore potential strategies to mitigate its impact. This review examines dialysis's environmental impact, resource recycling methods, and plant-based diets for kidney health. Recent research highlights the advantages of plant-based diets in managing and preventing chronic kidney disease (CKD) and its complications. Integrating these practices can significantly lessen the environmental impact of nephrology. PURPOSE OF REVIEW/OBJECTIVE:The aim of this study is to discuss the bidirectional relationship of climate change and kidney disease and the impact of nephrology on climate change and to discuss potential solutions. RECENT FINDINGS/RESULTS:Each dialysis session consumes significant amounts of resource; reusing them will aid the environment. Plant-based diets slow renal disease and have a lower carbon footprint, making them ecologically friendly. SUMMARY/CONCLUSIONS:Climate change is a growing threat to population health and healthcare. Rising temperatures raise the risk of kidney problems. Dialysis treatments also impact the environment through its high resource requirements while generating high volumes of waste and greenhouse gases. Opportunities exist to reduce the environmental impact of dialysis treatments. Plant-based diets serve to benefit both kidney disease and the environment.

PURPOSE/OBJECTIVE:This study explores coaching during transition from medical school to residency through the perspectives of residents and faculty coaches participating in a coaching program from residency match through the first year of residency. METHOD/METHODS:From January to September 2020, 15 faculty coaches in internal medicine, obstetrics and gynecology, emergency medicine, orthopedics, and pathology participated in a synchronous, in-person coaching training course. All 94 postgraduate year 1 residents in these 5 training programs participated. Between November 2021 and March 2022, focus groups were held with interns from all residency programs participating in the program. Interviews were conducted with faculty coaches in February 2022. Faculty and residents discussed their experiences with and perceptions of coaching. De-identified transcripts were coded, and researchers organized these codes into broader categories, generated cross-cutting themes from the concepts described in both cohorts, and proposed a model for the potential of coaching to support the transition to residency. Descriptive themes were constructed and analytic themes developed by identifying concepts that crossed the data sets. RESULTS:Seven focus groups were held with 39 residents (42%). Residents discussed the goals of a coaching program, coach attributes, program factors, resident attributes, and the role of the coach. Coaches focused on productivity of coaching, coaching skills and approach, professional development, and scaffolding the coaching experience. Three analytic themes were created: (1) coaching as creating an explicit curriculum for growth through the transition to residency, (2) factors contributing to successful coaching, and (3) ways in which these factors confront graduate medical education norms. CONCLUSIONS:Learner and faculty perspectives on coaching through the transition to residency reveal the potential for coaching to make an explicit and modifiable curriculum for professional growth and development. Creating structures for coaching in graduate medical education may allow for individualized professional development, improved mindset, self-awareness, and self-directed learning.
