Development of a Tool to Measure Student Perceptions of Equity and Inclusion in Medical Schools.

Importance: Creating an inclusive and equitable learning environment is a national priority. Nevertheless, data reflecting medical students' perception of the climate of equity and inclusion are limited. Objective: To develop and validate an instrument to measure students' perceptions of the climate of equity and inclusion in medical school using data collected annually by the Association of American Medical Colleges (AAMC). Design, Setting, and Participants: The Promoting Diversity, Group Inclusion, and Equity tool was developed in 3 stages. A Delphi panel of 9 members identified survey items from preexisting AAMC data sources. Exploratory and confirmatory factor analysis was performed on student responses to AAMC surveys to construct the tool, which underwent rigorous psychometric validation. Participants were undergraduate medical students at Liaison Committee on Medical Education-accredited medical schools in the US who completed the 2015 to 2019 AAMC Year 2 Questionnaire (Y2Q), the administrations of 2016 to 2020 AAMC Graduation Questionnaire (GQ), or both. Data were analyzed from August 2020 to November 2023. Exposures: Student race and ethnicity, sex, sexual orientation, and socioeconomic status. Main Outcomes and Measures: Development and psychometric validation of the tool, including construct validity, internal consistency, and criterion validity. Results: Delphi panel members identified 146 survey items from the Y2Q and GQ reflecting students' perception of the climate of equity and inclusion, and responses to these survey items were obtained from 54 906 students for the Y2Q cohort (median [IQR] age, 24 [23-26] years; 29 208 [52.75%] were female, 11 389 [20.57%] were Asian, 4089 [7.39%] were multiracial, and 33 373 [60.28%] were White) and 61 998 for the GQ cohort (median [IQR] age, 27 [26-28] years; 30 793 [49.67%] were female, 13 049 [21.05%] were Asian, 4136 [6.67%] were multiracial, and 38 215 [61.64%] were White). Exploratory and confirmatory factor analyses of student responses identified 8 factors for the Y2Q model (faculty role modeling; student empowerment; student fellowship; cultural humility; faculty support for students; fostering a collaborative and safe environment; discrimination: race, ethnicity, and gender; and discrimination: sexual orientation) and 5 factors for the GQ model (faculty role modeling; student empowerment; faculty support for students; discrimination: race, ethnicity, and gender; and discrimination: sexual orientation). Confirmatory factor analysis indicated acceptable model fit (root mean square error of approximation of 0.05 [Y2Q] and 0.06 [GQ] and comparative fit indices of 0.95 [Y2Q] and 0.94 [GQ]). Cronbach α for individual factors demonstrated internal consistency ranging from 0.69 to 0.92 (Y2Q) and 0.76 to 0.95 (GQ). Conclusions and Relevance: This study found that the new tool is a reliable and psychometrically valid measure of medical students' perceptions of equity and inclusion in the learning environment.

Pediatric Endocrinology Milestones 2.0-guide to their implementation.

The Milestones were initiated by the Accreditation Council for Graduate Medical Education (ACGME) to provide a framework for monitoring a trainee's progression throughout residency/fellowship. The Milestones describe stepwise skill progression through six core domains of clinical competency: Patient Care, Medical Knowledge, Interpersonal and Communication Skills, Practice-based Learning and Improvement, Professionalism, and Systems-based Practice. Since their introduction in 2013, several barriers to implementation have emerged. Thus, the ACGME launched the Milestones 2.0 project to develop updated specialty-specific milestones. The Pediatric Endocrinology Milestones 2.0 project aimed to improve upon Milestones 1.0 by addressing common limitations, providing resources for faculty to easily incorporate milestones into their assessment of trainees, and adding sub-competencies in health disparities, patient safety, and physician well-being.This paper reviews the development of the Pediatric Endocrinology Milestones 2.0 including the major changes from Milestones 1.0, development of the Supplemental Guide, and how Milestones 2.0 can be applied at the program level. Although use of the Milestones are required only for ACGME programs, the tools provided in Milestones 2.0 are applicable to fellowship programs worldwide.

Successful Management of Cushing Syndrome From Ectopic ACTH Secretion in an Adolescent With Osilodrostat.

A previously healthy 11-year-old male was found to have a mass in the pancreatic head after several months of abdominal pain and jaundice. Pathology was consistent with a World Health Organization grade 2 pancreatic neuroendocrine tumor. He developed refractory hypertension and was found to have Cushing syndrome from ectopic ACTH secretion, with oligometastatic liver disease. He underwent surgical resection of the pancreatic tumor and metastases. Postoperatively, his Cushing syndrome resolved, but it reemerged 1 year later in the setting of disease recurrence. He was not a candidate for bilateral adrenalectomy. Ketoconazole therapy was inadequate and he was started on metyrapone, lanreotide, cabergoline, and spironolactone. Although this regimen was well-tolerated, his Cushing syndrome recurred 4 months later as his metastatic disease burden increased. Osilodrostat was begun and the dose was gradually increased in response to his uncontrolled Cushing syndrome. Osilodrostat resulted in rapid improvement and eventual normalization of his urinary free cortisol at a dose of 18 mg twice daily. He had no adverse effects. This rare case highlights the successful off-label use of osilodrostat, a medication intended for refractory Cushing disease in adult patients, in a pediatric patient with Cushing syndrome caused by ectopic ACTH secretion.

Hormonal Determinants of Growth and Weight Gain in the Human Fetus and Preterm Infant.

The factors controlling linear growth and weight gain in the human fetus and newborn infant are poorly understood. We review here the changes in linear growth, weight gain, lean body mass, and fat mass during mid- and late gestation and the early postnatal period in the context of changes in the secretion and action of maternal, placental, fetal, and neonatal hormones, growth factors, and adipocytokines. We assess the effects of hormonal determinants on placental nutrient delivery and the impact of preterm delivery on hormone expression and postnatal growth and metabolic function. We then discuss the effects of various maternal disorders and nutritional and pharmacologic interventions on fetal and perinatal hormone and growth factor production, growth, and fat deposition and consider important unresolved questions in the field.

Perspectives on National Institutes of Health Funding Requirements for Racial and Ethnic Diversity Among Medical Scientist Training Program Leadership.

Importance: Since 1964, the National Institutes of Health (NIH) has funded the Medical Scientist Training Program (MSTP) MD-PhD program at medical schools across the US to support training physician-scientists. Recent studies have suggested that MSTPs have consistently matriculated more students from racial and ethnic backgrounds historically underrepresented in science than MD-PhD programs without NIH funding; however, the underlying basis for the increased diversity seen in NIH-funded MSTPs is poorly understood. Objective: To investigate how administrators and faculty perceive the impact of MSTP status on MD-PhD program matriculant racial and ethnic diversity. Design, Setting, and Participants: This qualitative study used a positive deviance approach to identify 9 high-performing and 3 low-performing MSTPs based on the percentage of students underrepresented in science who matriculated into the program between 2014 and 2018. This study, a subanalysis of a larger study to understand recruitment of students underrepresented in science at MSTPs, focused on in-depth qualitative interviews, conducted from October 26, 2020, to August 31, 2022, of 69 members of MSTP leadership, including program directors, associate and assistant program directors, and program administrators. Main Outcomes and Measures: The association of NIH funding with institutional priorities, programs, and practices related to MD-PhD program matriculant racial and ethnic diversity. Results: The study included 69 participants (mean [SD] age, 53 [10] years; 38 women [55%]; 13 African American or Black participants [19%], 6 Asian participants [9%], 12 Hispanic participants [17%], and 36 non-Hispanic White participants [52%]). A total of 51 participants (74%) were in administrative roles, and 18 (26%) were faculty involved in recruitment. Five themes emerged from the data: (1) by tying MSTP funding to diversity efforts, the NIH created a sense of urgency among MSTP leadership to bolster matriculant diversity; (2) MD-PhD program leadership leveraged the changes to MSTP grant review to secure new institutional investments to promote recruitment of students underrepresented in science; (3) MSTPs increasingly adopted holistic review to evaluate applicants to meet NIH funding requirements; (4) MSTP leadership began to systematically assess the effectiveness of their diversity initiatives and proactively identify opportunities to enhance matriculant diversity; and (5) although all MSTPs were required to respond to NIH criteria, changes made by low-performing programs generally lacked the robustness demonstrated by high-performing programs. Conclusions and Relevance: This study suggests that NIH funding requirements may be a powerful incentive to promote diversity and positively affect representation of students underrepresented in science in the biomedical scientific workforce.

Thyroid Nodules on Ultrasound in Children and Young Adults: Comparison of Diagnostic Performance of Radiologists' Impressions, ACR TI-RADS, and a Deep Learning Algorithm.

BACKGROUND. In current clinical practice, thyroid nodules in children are generally evaluated on the basis of radiologists' overall impressions of ultrasound images. OBJECTIVE. The purpose of this article is to compare the diagnostic performance of radiologists' overall impression, the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS), and a deep learning algorithm in differentiating benign and malignant thyroid nodules on ultrasound in children and young adults. METHODS. This retrospective study included 139 patients (median age 17.5 years; 119 female patients, 20 male patients) evaluated from January 1, 2004, to September 18, 2020, who were 21 years old and younger with a thyroid nodule on ultrasound with definitive pathologic results from fine-needle aspiration and/or surgical excision to serve as the reference standard. A single nodule per patient was selected, and one transverse and one longitudinal image each of the nodules were extracted for further evaluation. Three radiologists independently characterized nodules on the basis of their overall impression (benign vs malignant) and ACR TI-RADS. A previously developed deep learning algorithm determined for each nodule a likelihood of malignancy, which was used to derive a risk level. Sensitivities and specificities for malignancy were calculated. Agreement was assessed using Cohen kappa coefficients. RESULTS. For radiologists' overall impression, sensitivity ranged from 32.1% to 75.0% (mean, 58.3%; 95% CI, 49.2-67.3%), and specificity ranged from 63.8% to 93.9% (mean, 79.9%; 95% CI, 73.8-85.7%). For ACR TI-RADS, sensitivity ranged from 82.1% to 87.5% (mean, 85.1%; 95% CI, 77.3-92.1%), and specificity ranged from 47.0% to 54.2% (mean, 50.6%; 95% CI, 41.4-59.8%). The deep learning algorithm had a sensitivity of 87.5% (95% CI, 78.3-95.5%) and specificity of 36.1% (95% CI, 25.6-46.8%). Interobserver agreement among pairwise combinations of readers, expressed as kappa, for overall impression was 0.227-0.472 and for ACR TI-RADS was 0.597-0.643. CONCLUSION. Both ACR TI-RADS and the deep learning algorithm had higher sensitivity albeit lower specificity compared with overall impressions. The deep learning algorithm had similar sensitivity but lower specificity than ACR TI-RADS. Interobserver agreement was higher for ACR TI-RADS than for overall impressions. CLINICAL IMPACT. ACR TI-RADS and the deep learning algorithm may serve as potential alternative strategies for guiding decisions to perform fine-needle aspiration of thyroid nodules in children.

Pharmacologic Weight Management in the Era of Adolescent Obesity.

CONTEXT: Pediatric obesity is a serious health problem in the United States. While lifestyle modification therapy with dietary changes and increased physical activity are integral for the prevention and treatment of mild to moderate obesity in youth, only a modest effect on sustained weight reduction is observed in children and young adults with severe obesity. This underscores the need for additional evidence-based interventions for children and adolescents with severe obesity, including pharmacotherapy, before considering invasive procedures such as bariatric surgery. EVIDENCE ACQUISITION: This publication focuses on recent advances in pharmacotherapy of obesity with an emphasis on medications approved for common and rarer monogenic forms of pediatric obesity. EVIDENCE SYNTHESIS: We review medications currently available in the United States, both those approved for weight reduction in children and "off-label" medications that have a broad safety margin. CONCLUSION: It is intended that this review will provide guidance for practicing clinicians and will encourage future exploration for successful pharmacotherapy and other interventions for obesity in youth.

An endocrine perspective on menstrual suppression for adolescents: achieving good suppression while optimizing bone health.

Suppression of menstruation and/or ovarian function in adolescent girls may be desired for a variety of reasons. Numerous medical options exist. The choice of the appropriate modality for an individual patient depends on several factors based on differences in the efficacy of achieving menstrual suppression as well as in their side effect profiles. Adolescence is also a period of bone mass accrual in girls, and several of these modalities may negatively influence peak bone mass. This review focuses on the efficacy of achieving menstrual suppression and the effect on bone health of the various options through an overview of the current literature and also highlights areas in need of further research.

Sustained Impact of a Pediatric Resident-Led Patient Safety Council.

OBJECTIVES: The aim of the study was to evaluate the impact of a resident-led patient safety council. This study measured change in resident perceptions and knowledge of safety issues for 3 years, as well as behavioral choices to participate in patient safety activities during and after residency. METHODS: Pediatric residents formed a resident-led safety council to engage their peers in patient safety activities. Surveys were distributed annually from 2013 to 2015 to measure residents' perception and knowledge surrounding patient safety. The number of patient safety reports submitted by residents was tracked for the same period. In addition, recent graduates were surveyed to assess the influence of the council on postresidency involvement in patient safety. RESULTS: Resident perception of the institutional culture of safety improved and knowledge of basic patient safety concepts increased. The number of resident-submitted safety reports increased from 6.2 to 15.2 reports per month in the 2013 and 2015 academic years, respectively. Surveys of recent graduates suggest that involvement with the safety council during residency fostered future engagement in patient safety. CONCLUSIONS: This resident-led council models successful involvement of trainees in system-based patient safety. Such involvement can help shape the safety culture within a training program and encourages continued participation in patient safety after residency completion.

Role of GLP-1 Receptor Agonists in Pediatric Obesity: Benefits, Risks, and Approaches to Patient Selection.

PURPOSE OF REVIEW: Effective treatments for pediatric obesity are limited. Glucagon-like peptide-1 receptor (GLP-1R) agonists have emerged as therapeutic agents for obesity in adults and have shown benefits outside of weight loss. Here we explore the evidence for GLP-1R agonist use in pediatric obesity. RECENT FINDINGS: Emerging evidence suggests that GLP-1R agonists have a role in pediatric obesity treatment. A recently published, randomized, placebo-controlled trial found a greater reduction in BMI z-score (- 0.22 SDs) in adolescents receiving liraglutide compared with placebo. As in adults, gastrointestinal adverse effects were commonly seen. GLP-1R agonists appear to perform favorably compared with other approved pharmacological agents for pediatric obesity. However, heterogeneity in weight loss response, cost, side effects, and need for injections may limit their use in many pediatric patients. Rather than broadly applying this therapy if it is approved, we suggest careful patient selection and monitoring by clinicians pending further studies.

Management and Appropriate Use of Diazoxide in Infants and Children with Hyperinsulinism.

BACKGROUND: The diagnosis of hypoglycemia and the use of diazoxide have risen in the last decade. Diazoxide is the only Food and Drug Agency-approved pharmacologic treatment for neonatal hypoglycemia caused by hyperinsulinism (HI). Recent publications have highlighted that diazoxide has serious adverse effects (AEs) such as pulmonary hypertension (2-3%) and neutropenia (15%). Despite its increasing use, there is little information regarding dosing of diazoxide and/or monitoring for AEs. METHODS: We convened a working group of pediatric endocrinologists who were members of the Drug and Therapeutics Committee of the Pediatric Endocrine Society (PES) to review the available literature. Our committee sent a survey to its PES members regarding the use of diazoxide in their endocrine practices. Our review of the results concluded that there was substantial heterogeneity in usage and monitoring for AEs for diazoxide among pediatric endocrinologists. CONCLUSIONS: Based on our extensive literature review and on the lack of consensus regarding use of diazoxide noted in our PES survey, our group graded the evidence using the framework of the Grading of Recommendations, Assessment, Development and Evaluation Working Group, and has proposed expert consensus practice guidelines for the appropriate use of diazoxide in infants and children with HI. We summarized the information on AEs reported to date and have provided practical ideas for dosing and monitoring for AEs in infants treated with diazoxide.

Achieving Gender Equity Is Our Responsibility: Leadership Matters.

Across academic medicine, and particularly among faculty and medical school leadership, the status quo is unacceptable when it comes to gender diversity, equity, and inclusion. The Association of American Medical Colleges has launched a bold gender equity initiative, endorsed by its Board of Directors, to implore academic medical institutions to take meaningful and effective actions.Defining what progress should look like to guide these actions is worth deeper exploration. It is not enough to measure the representation of different genders at various levels of leadership within our institutions. Research and experience we share suggests more must be done, especially for women of diverse racial and ethnic backgrounds. What is needed is a fundamental conversation about privilege, intersectionality across different backgrounds, and progress.Institutional leaders have a choice to make. Will we make gender equity a top priority system-wide because we recognize that doing so leads to organizational excellence? Do we understand that establishing a robust, comprehensive definition of gender equity and how it is practiced will result in better outcomes for all? And are we ready and able to prioritize and be accountable for efforts that are measurable, with clear definitions of progress; driven and reinforced by leadership directives; inclusive of all, including men as well as women of diverse backgrounds and orientations; and systemic rather than ad-hoc? Implementing such actions requires initiating difficult conversations, making conscious choices, and modeling best practices from leaders who have successfully made gender equity a priority.

Vivre sans ma voiture : une intervention pour soutenir les Canadiens-francophones âgés.

The cessation of driving is a difficult transition for the elderly, but it can be facilitated through interventions. The purpose of this study was to explore the satisfaction, usefulness and applicability of the CarFreeMe intervention in the French-Canadian context. A qualitative clinical research device was used on ten older adults aged between 61 and 90 years. The participants had stopped driving within the last twelve months or were planning to stop driving in the near future and did not have cognitive impairments. After the intervention, the participants were generally satisfied and reported on its usefulness and applicability in a French-Canadian context. In addition, they identified the positive impacts related to their social involvement as they re-engaged in or pursued their significant activities. Further research is required to assess the intervention's effects and the practicability of implementing it in Canada.

Ghrelin regulation of glucose metabolism.

Ghrelin and its receptor, the growth hormone secretagogue receptor 1a (GHSR1a), are implicated in the regulation of glucose metabolism via direct actions in the pancreatic islet, as well as peripheral insulin-sensitive tissues and the brain. Although many studies have explored the role of ghrelin in glucose tolerance and insulin secretion, a complete mechanistic understanding remains to be clarified. This review highlights the local expression and function of ghrelin and GHSR1a in pancreatic islets and how this axis may modulate insulin secretion from pancreatic ß-cells. Additionally, we discuss the effect of ghrelin on in vivo glucose metabolism in rodents and humans, as well as the metabolic circumstances under which the action of ghrelin may predominate.

The Association Between Pediatric Faculty Factors and Resident Physician Ratings of Teaching Effectiveness.

Background. Faculty factors not inherently related to teaching effectiveness can influence teaching ratings. No studies have focused on pediatric faculty who possess unique differences from general medical faculty. Methods. We designed a retrospective observational study to compare faculty teaching ratings with measured factors across 3 academic pediatric institutions. Results. Our study included 196 faculty members. The majority (76%) of variation in teaching effectiveness ratings was not accounted for by any measured variable, but 24% was attributed to measurable factors. Increased resident exposure (sequential r 2 = .10, P < .0001) significantly affected teaching effectiveness. Variation between resident ratings of pediatric faculty teaching can be partially explained by measured factors not necessarily related to teaching effectiveness. Conclusions. The identification of faculty factors that significantly contribute to rating variation can enhance interpretation of these rating.

A Stochastic Model of Consensus Reaching in Committee Decisions for Faculty Advancement, Promotion and Tenure: Does Diversity Matter?

PURPOSE: There are considerable gender and racial disparities in academic promotions regardless of academic qualifications, suggesting bias. The investigators studied the academic promotions process by simulating the work of Advancement, Promotion and Tenure (APT) committees and applying a mathematical model to assess the impact of diversity on consensus reaching. METHOD: The study targeted academic faculty during an annual Association of American Medical Colleges (AAMC) meeting. Participants evaluated the academic dossier of a male Assistant Professor with a focus on community engagement during four simulations. All dossiers were identical, with the singular exception of the candidate's race (white vs. black). Committee composition varied with respect to racial diversity. Participants scored the candidate before and after the deliberations. The DeGroot Model was used to compare individual scoring to group convergence. RESULTS: While there was no statistically significant difference in the candidate's overall scores between the groups, the least diverse groups rated the candidate the lowest (p = 0.0595). Participants ranked activities related to diversity and equity as the least important. Moreover, criteria deliberated more heavily showed significant score changes after deliberation. Lastly, ambiguity about the review process at various institutions was reported by project participants, increasing the opportunity for bias in real world situations. CONCLUSIONS: While there was not enough statistical power to measure intragroup differences, the model shows promise in illuminating how individual perceptions, committee composition and group dynamics sway consensus reaching. The model also suggests that social research, community engagement and diversity work do not carry the same weight as traditional scholarship, impacting the career trajectory of minority scholars. The model can be used to evaluate bias not only in academic promotions but also in admissions, hiring and grant review. This will allow improved methods and processes for equitable academic performance reviews, enhancing the career trajectory and retention of minority scholars.

Interaction of GLP-1 and Ghrelin on Glucose Tolerance in Healthy Humans.

Emerging evidence supports the importance of ghrelin to defend against starvation-induced hypoglycemia. This effect may be mediated by inhibition of glucose-stimulated insulin secretion as well as reduced insulin sensitivity. However, administration of ghrelin during meal consumption also stimulates the release of glucagon-like peptide 1 (GLP-1), an incretin important in nutrient disposition. The objective of this study was to evaluate the interaction between ghrelin and GLP-1 on parameters of glucose tolerance following a mixed-nutrient meal. Fifteen healthy men and women completed the study. Each consumed a standard meal on four separate occasions with a superimposed infusion of 1) saline, 2) ghrelin, 3) the GLP-1 receptor antagonist exendin(9-39) (Ex9), or 4) combined ghrelin and Ex9. Similar to previous studies, infusion of ghrelin caused glucose intolerance, whereas Ex9 had a minimal effect. However, combined ghrelin and Ex9 resulted in greater postprandial glycemia than either alone, and this effect was associated with impaired ß-cell function and decreased glucose clearance. These findings suggest that in the fed state, stimulation of GLP-1 mitigates some of the effect of ghrelin on glucose tolerance. This novel interaction between gastrointestinal hormones suggests a system that balances insulin secretion and glucose disposal in the fed and fasting states.

Sustaining a culture of practice development in an acute adolescent inpatient mental health unit.

TOPIC: It is recognized that facilitating change in workplace culture is a significant challenge in healthcare service delivery. Practice development strategies and principles provide a framework for initiating and sustaining programs focused on enhancing patient-centered care by concentrating on the therapeutic attributes of nursing. However, little literature exists on explicating "what worked" in practice development programs. PURPOSE: This paper details the processes, people, resources, and relationships that enabled the successful implementation, and led to the sustainability, of a practice development program employed in an acute adolescent mental health unit in Sydney, Australia. SOURCES USED: Following an external review of the unit, a meeting of key stakeholders was convened and subsequently an advisory panel formed to address specific issues facing nursing staff. This process resulted in the development of an educational package and adoption of the tidal model as the framework for mental health nursing practice in the unit. Clinical reasoning sessions and journal article presentations were incorporated to consolidate and maintain the change in nursing care. CONCLUSIONS: A planned, structured, and inclusive practice development programhas transformed the nursing culture and vastly improved the care provided to adolescents presenting in acute states of distress to this mental health unit.

Acute administration of acyl, but not desacyl ghrelin, decreases blood pressure in healthy humans.

OBJECTIVE: To compare the effects of acyl ghrelin (AG) and desacyl ghrelin (DAG) on blood pressure (BP), heart rate (HR) and other autonomic parameters in healthy humans and to elucidate the hormonal mechanisms through which AG could exert its cardiovascular effects. DESIGN: Seventeen healthy participants underwent frequent monitoring of systolic (sBP) and diastolic blood pressure (dBP), HR, respiratory rate (RR) and body surface temperature (Temp) during continuous infusion of AG, DAG, combined AG + DAG or saline control before and during an IV glucose tolerance test on 4 separate days. Plasma catecholamines, renin and aldosterone levels were also measured. Differences in outcome measures between treatment groups were assessed using mixed-model analysis. RESULTS: Compared to the saline control, AG and combined AG + DAG infusions decreased sBP, dBP, mean arterial blood pressure (MAP), HR and Temp. In contrast, DAG infusion did not alter BP, RR or Temp, but did decrease HR. The AG and AG + DAG infusions also raised plasma aldosterone levels compared to saline (P < 0.001) without affecting renin or catecholamine levels. CONCLUSIONS: The decrease in BP, HR, RR and Temp with AG infusion suggests mediation through the autonomic nervous system. The lack of response to DAG suggests that these autonomic effects require activation of the ghrelin receptor.
