Introduction: This standardized-patient-based module prepares medical students to take inclusive, comprehensive sexual histories from patients of all sexual orientations and gender identities. Health disparities faced by lesbian, gay, bisexual, transgender, and queer (LGBTQ) people are at least partially the result of inadequate access to health care and insufficient provider training. This module incorporates implicit bias activities to emphasize the important role providers can play in mitigating these disparities through compassionate, competent care. Furthermore, two of the three included cases highlight the negative impact sexual dysfunction can have on emotional well-being. Methods: Over 3 hours, students participate in a 30-minute large-group lecture and three 40-minute small-group standardized patient encounters with debrief. Prework consists of a short video on sexual history taking, assigned readings, and an implicit bias activity. These materials are included in this resource, along with lecture slides, facilitator guide, and standardized patient cases. Though the cases are adaptable to all levels of medical education, this module is designed for second-year and early third-year medical students. Results: Qualitative student evaluations were positive, and postparticipation surveys revealed statistically significant improvement in comfort with their ability to take a sexual history in general, and take one from patients with a differing sexual orientation. Deployed in the second year of our Doctoring curriculum, this module continues to receive positive evaluations. Discussion: Introducing these skills begins to address the curricular deficiencies seen across medical education and lays the foundation for a more competent health care workforce to address the needs of LGBTQ patients.
e17075 Background: Despite the correlation between tumor infiltrating lymphocytes and long-term survival, immune-based therapies have underperformed for the treatment of ovarian cancer. This is attributed to an immune suppressive intraperitoneal microenvironment. With evidence that T cell dysfunction in the ovarian tumor environment is not reflected peripherally, we hypothesized that anatomically restricted T cell subsets play a role in local disease regulation. High expression of integrin α4 (CD49d) is selectively seen on peritoneal T cells in patients and healthy mice. Here we tested whether CD49d(high) CD8 T cells also contribute to anti-tumor immunity in ovarian cancer models. Methods: Using a syngeneic immune competent model of high grade serous ovarian cancer (ID8ova), we evaluated the phenotype of CD49d(high) T cells at varying stages of intraperitoneal disease by flow cytometry. Antigen specificity was tested using a SIINFEKL/H-2Kb NIH tetramer assay. Results: CD49d is highly expressed by peritoneal CD8 T cells but not by splenocytes in tumor-bearing mice (29.8% vs. 3.3% of CD8 cells respectively). Supporting a role in anti-tumor immunity, 92% of tumor antigen-specific CD8 T cells in the peritoneal cavity expressed high CD49d. While the proportion of peritoneal CD8 cells that express high CD49d is similar in healthy and tumor-bearing mice, CD49d(high)CD8 cells upregulate the expression of co-inhibitory receptors with tumor progression. At late stages of the disease, PD-1, TIM3, and LAG3 are exclusively expressed by peritoneal CD49d(high) cells (range 94.7 +/- 3.05%). Consistent with our prior data, PD1+TIM3+LAG3+ CD8 T cells were not present in the spleen, confirming the anatomic specificity of this lymphocyte subset. Conclusions: These findings add to the accumulating evidence that tumor immunity is locally regulated and identify an IP specific subset of CD8 T cells that could be selectively targeted with immune checkpoint blockade. We predict that strategies directing immune therapy to the peritoneal tumor microenvironment will enhance treatment efficacy and limit off-target toxicities in women with ovarian cancer.
Purpose: Treatment for the Morton neuroma is diverse, yet there is no clearly superior method of treatment 1 . Targeted muscle reinnervation (TMR) has been effective in neuroma prevention and treatment 2 , however few papers espouse the use of TMR in the foot. Here we aim to comprehensively categorize the location and size of potential TMR targets in the foot and evaluate the feasibility of TMR. Methods:Comprehensive dissection and measurement of the location and diameter of motor entry points (MEP) was performed on ten fresh cadaveric lower extremities. Results/Conclusion:We found consistency in identification of MEP target locations for both the medial and lateral plantar nerve distributions. We also measured the diameter of the distal sensory nerves and found a favorable sensory-to-MEP diameter ratio of less than 2:1 3 . Through this anatomic study we provide a comprehensive map for the surgical approach for TMR in the foot.
