Twelve tips for incorporating and teaching sexual and gender minority health in medical school curricula.

The World Health Organization has identified many barriers to improving the health of lesbian, gay, bisexual, and transgender (LGBT) patients, including challenges to incorporating and teaching about healthcare for such patients, which we call "sexual and gender minority" (SGM) health content. These challenges include structural and logistical barriers to incorporating SGM health content into undergraduate medical curricula, as well as lack of support in identifying high-quality pedagogical methods for teaching this material. Here, we provide twelve tips for incorporating and teaching SGM health curricular content in undergraduate medical education, including resources and strategies to support individual educators. Based on our success in developing and implementing this content, we believe that our approach can be effectively used by individual educators aiming to incorporate SGM health curricular material into their teaching, and to support individuals or groups championing the inclusion of a SGM health topical sequence in medical curricula.

Atypical case of classical polyarteritis nodosa: alveolar hemorrhage and positive antineutrophil cytoplasmic antibody
.

Classical polyarteritis nodosa (PAN) is a necrotizing arteritis affecting medium-sized vessels. A 73-year-old gentleman who presented with progressive anemia and scant hemoptysis developed acute kidney injury over the course of hospital admission. Kidney biopsy was initially interpreted as consistent with cephalosporin-associated acute interstitial nephritis (AIN) and acute tubular injury (ATI). After oral prednisone (5 days), the patient was discharged with improving serum creatinine. Two days later, he presented with diffuse alveolar hemorrhage. C-ANCA, ANA, anti-GBM, C4, cryoglobulin, HIV, HBV, and HCV studies were negative. P-ANCA was positive. Biopsy tissue was revisited, in addition to AIN, ATI, and non-caseating interstitial granulomas, lymphocytic infiltration of medium-sized vessels with endothelitis consistent with a diagnosis of PAN was noted. This case is notable for its atypical clinical presentation - alveolar hemorrhage - and atypical laboratory presentation - P-ANCA positivity for classical PAN. We describe an atypical presentation of PAN as a means of reviewing the range of clinical presentations, criteria for diagnosis, and treatment approaches for PAN and drug-induced vasculitis, which may present similar to PAN.

Congenital anomalies in low- and middle-income countries: the unborn child of global surgery.

Surgically correctable congenital anomalies cause a substantial burden of global morbidity and mortality. These anomalies disproportionately affect children in low- and middle-income countries (LMICs) due to sociocultural, economic, and structural factors that limit the accessibility and quality of pediatric surgery. While data from LMICs are sparse, available evidence suggests that the true human and financial cost of congenital anomalies is grossly underestimated and that pediatric surgery is a cost-effective intervention with the potential to avert significant premature mortality and lifelong disability.

Congenital anomalies in the context of global surgery.

Surgery is increasingly recognized as an essential component of global health development. This article will review the state of global pediatric surgery, utilizing congenital anomalies as a framework in which to discuss the promise of pediatric surgery in reducing the global burden of disease. Congenital anomalies are responsible for a substantial burden of morbidity and mortality in low- and middle-income countries (LMICs), as well as significant emotional and economic harms to the families of children with congenital anomalies. Limited pediatric surgical capacity in many LMICs has culminated in a devastating burden of avertable disability and death. Pediatric surgery is an effective and cost-effective means to reduce this burden. Pediatric surgeons must continue to drive the growth of global pediatric surgery by engaging in clinical practice, educational partnerships, and research initiatives.

Specialty Choice Among Sexual and Gender Minorities in Medicine: The Role of Specialty Prestige, Perceived Inclusion, and Medical School Climate.

PURPOSE: Sexual and gender minorities (SGMs) in medicine experience unique stressors in training. However, little is known about SGM specialty choice. This study examined predictors of SGM specialty choice, associations between specialty prestige and perceived SGM inclusion, and self-reported influences on specialty choice. METHODS: Medical trainees and practitioners (358 SGM, 1528 non-SGM) were surveyed online. We operationalized specialty choice at the individual level as respondents' specialty of practice; at the specialty level, as a percentage of SGM respondents in each specialty. We examined specialty prestige, perceived SGM inclusivity, and medical school climate as predictors of SGM specialty choice, and we compared additional influences on specialty choice between SGM and non-SGM. RESULTS: The percentage of SGM in each specialty was inversely related to specialty prestige (P = 0.001) and positively related to perceived SGM inclusivity (P = 0.01). Prestigious specialties were perceived as less SGM inclusive (P < 0.001). Medical school climate did not predict specialty prestige (P = 0.82). SGM were more likely than non-SGM to indicate that sexual and gender identity strongly influenced specialty choice (P < 0.01). SGM most frequently rated personality fit, specialty content, role models, and work-life balance as strong influences on specialty choice. Exposure as a medical student to SGM faculty did not predict specialty prestige among SGM. CONCLUSION: Specialty prestige and perceived inclusivity predict SGM specialty choice. SGM diversity initiatives in prestigious specialties may be particularly effective by addressing SGM inclusion directly. Further research is needed to inform effective mentorship for SGM medical students. Exposure to SGM in medical training reduces anti-SGM bias among medical professionals, and SGM in medicine often assume leadership roles in clinical care, education, and research regarding SGM health. Supporting and promoting SGM diversity across the spectrum of medical specialties, therefore, represents a critical avenue to improve the care delivered to SGM populations and addresses the role of providers in the health disparities experienced by SGM.

Placental mesenchymal stromal cells rescue ambulation in ovine myelomeningocele.

UNLABELLED: Myelomeningocele (MMC)-commonly known as spina bifida-is a congenital birth defect that causes lifelong paralysis, incontinence, musculoskeletal deformities, and severe cognitive disabilities. The recent landmark Management of Myelomeningocele Study (MOMS) demonstrated for the first time in humans that in utero surgical repair of the MMC defect improves lower limb motor function, suggesting a capacity for improved neurologic outcomes in this disorder. However, functional recovery was incomplete, and 58% of the treated children were unable to walk independently at 30 months of age. In the present study, we demonstrate that using early gestation human placenta-derived mesenchymal stromal cells (PMSCs) to augment in utero repair of MMC results in significant and consistent improvement in neurologic function at birth in the rigorous fetal ovine model of MMC. In vitro, human PMSCs express characteristic MSC markers and trilineage differentiation potential. Protein array assays and enzyme-linked immunosorbent assay show that PMSCs secrete a variety of immunomodulatory and angiogenic cytokines. Compared with adult bone marrow MSCs, PMSCs secrete significantly higher levels of brain-derived neurotrophic factor and hepatocyte growth factor, both of which have known neuroprotective capabilities. In vivo, functional and histopathologic analysis demonstrated that human PMSCs mediate a significant, clinically relevant improvement in motor function in MMC lambs and increase the preservation of large neurons within the spinal cord. These preclinical results in the well-established fetal ovine model of MMC provide promising early support for translating in utero stem cell therapy for MMC into clinical application for patients. SIGNIFICANCE: This study presents placenta-derived mesenchymal stromal cell (PMSC) treatment as a potential therapy for myelomeningocele (MMC). Application of PMSCs can augment current in utero surgical repair in the well-established and rigorously applied fetal lamb model of MMC. Treatment with human PMSCs significantly and dramatically improved neurologic function and preserved spinal cord neuron density in experimental animals. Sixty-seven percent of the PMSC-treated lambs were able to ambulate independently, with two exhibiting no motor deficits whatsoever. In contrast, none of the lambs treated with the vehicle alone were capable of ambulation. The locomotor rescue demonstrated in PMSC-treated lambs indicates great promise for future clinical trials to improve paralysis in children afflicted with MMC.

Development of a locomotor rating scale for testing motor function in sheep.

BACKGROUND/PURPOSE: Research to cure paralysis associated with myelomeningocele (MMC) is ongoing using the fetal sheep model of MMC. Despite decades of research using this model, no standardized motor function assessment exists. The purpose of this study is to develop a sensitive and reliable locomotor scale for assessing the functional status of sheep. METHODS: Twenty lambs were used to develop and validate the locomotor scale. Lambs (n=15) underwent a surgically created MMC defect at gestational age (GA) 75 days, followed by repair with various methods at GA 100. One lamb underwent a sham operation (n=1). Normal lambs (n=4) served as controls. All lambs were born via spontaneous vaginal delivery, and motor function was assessed for 24 hours. A locomotor rating scale was developed based on behavioral observations of lambs. Inter-rater reliability testing was performed to determine if the scale could be reliably applied by different raters. RESULTS: Observations led to the definition of 7 categories of locomotor recovery. A scoring system was developed to rank these categories. The scale captured a wide variety of neurologic outcomes. Inter-rater reliability revealed minimal variability between examiners (average standard deviation ±0.431). The average score for all raters was within 1 point of the consensus score 100% of the time. CONCLUSIONS: The sheep locomotor rating scale is capable of capturing subtle differences in neurologic function with minimal inter-rater variability. We propose a standardized rating scale for neurologic outcomes and believe this is a critical component for assessing the validity of experimental treatments to cure paralysis in MMC.
