RESUMEN

INTRODUCTION: Plastic and reconstructive surgery is among the most competitive specialties in the National Resident Matching Program match. Though efforts to institute unbiased and equitable measures of an applicant's success have been made, many barriers still hinder suitable applicants from successfully matching. We sought to identify whether interview day influenced applicants' likelihood of being ranked favorably in both independent and integrated plastic surgery residency programs at a single academic institution. METHODS: Data from 10 years of independent plastic surgery applicants and 8 years of integrated plastic surgery applicants were queried. Data regarding whether applicants were interviewed on day 1, day 2, or during subinternships (integrated cohort only) and what number they were on the programs rank list were included in the analysis. RESULTS: A total of 226 independent applicants 237 integrated applicants were identified. For integrated applicants, those who interviewed on day 1 were weighted toward worse rank scores. Applicants who interviewed during their subinternship had a bimodal distribution either ranking favorably or poorly. Integrated applicants who interviewed on the second day were more likely to be ranked in the first quartile. For those who interviewed on day 1, the odds of being ranked in the last quartile was 2.34 times higher than those who interviewed on day 2 (p = 0.02). CONCLUSIONS: Our results demonstrating that interview day may influence an applicant's final rank in the MATCH. Further study is needed to determine if this effect is can be observed in other academic plastic surgery programs.

RESUMEN

Current imaging approaches used to monitor tumor progression can lack the ability to distinguish true progression from pseudoprogression. Simultaneous metabolic 2-deoxy-2-[18F]fluoro-D-glucose ([18F]FDG) positron emission tomography (PET) and magnetic resonance imaging (MRI) offers new opportunities to overcome this challenge by refining tumor identification and monitoring therapeutic responses to cancer immunotherapy. In the current work, spatial and quantitative analysis of tumor burden were performed using simultaneous [18F]FDG-PET/MRI to monitor therapeutic responses to a novel silicified cancer cell immunotherapy in a mouse model of disseminated serous epithelial ovarian cancer. Tumor progression was validated by bioluminescence imaging of luciferase expressing tumor cells, flow cytometric analysis of immune cells in the tumor microenvironment, and histopathology. While PET demonstrated the presence of metabolically active cancer cells through [18F]FDG uptake, MRI confirmed cancer-related accumulation of ascites and tissue anatomy. This approach provides complementary information on disease status without a confounding signal from treatment-induced inflammation. This work provides a possible roadmap to facilitate accurate monitoring of therapeutic responses to cancer immunotherapies.

RESUMEN

Vasopressor-induced ischemia of the hand, while relatively rare, is a severe complication in critically ill intensive care unit (ICU) patients requiring high concentrations of sympathomimetic pressors and often results in digit necrosis and amputation. Currently, there are no widely accepted approaches for treating this cause of peripheral digital ischemia. Case reports have demonstrated that reducing the concentration of vasopressors that patients are given may reverse the progression of ischemic events prior to necrosis. While this approach is at odds with the principle of "life over limb," it demonstrates that digit necrosis can be reversed, resulting in improved outcomes. Here, we present a therapeutic strategy for treating digital limb ischemia in the septic ICU patient without the need to lower systemic vasopressor dose by using locally injected botulinum toxin A into ischemic hands.

RESUMEN

The production of personalized cancer vaccines made from autologous tumour cells could benefit from mechanisms that enhance immunogenicity. Here we show that cancer vaccines can be made via the cryogenic silicification of tumour cells, which preserves tumour antigens within nanoscopic layers of silica, followed by the decoration of the silicified surface with pathogen-associated molecular patterns. These pathogen-mimicking cells activate dendritic cells and enhance the internalization, processing and presentation of tumour antigens to T cells. In syngeneic mice with high-grade ovarian cancer, a cell-line-based silicified cancer vaccine supported the polarization of CD4+ T cells towards the T-helper-1 phenotype in the tumour microenvironment, and induced tumour-antigen-specific T-cell immunity, resulting in complete tumour eradication and in long-term animal survival. In the setting of established disease and a suppressive tumour microenvironment, the vaccine synergized with cisplatin. Silicified and surface-modified cells from tumour samples are amenable to dehydration and room-temperature storage without loss of efficacy and may be conducive to making individualized cancer vaccines across tumour types.

RESUMEN

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.

RESUMEN

High-fat diet (HFD)-induced obesity is reaching worldwide proportions. In addition to causing obesity, HFDs also induce a variety of health disorders, which includes cognitive decline. Hippocampal function may be particularly vulnerable to the negative consequences of HFD, and it is suspected that 'primed' neuroinflammatory processes may mediate this response. To examine the link between diet, hippocampal function and neuroinflammation, male Wistar rats were fed a medium or HFD. Hippocampal memory function was measured using contextual pre-exposure fear conditioning (CPE-FC). Rats fed a HFD demonstrated impaired memory, an effect that was augmented with longer duration of HFD consumption. HFD-induced memory impairments were linked to potentiated levels of interleukin-1 beta (IL-1ß) protein in the hippocampus 2h after the foot-shock that occurs during CPE-FC. Central IL-1 receptor antagonism, with intracisterna magna (ICM) administration of hIL-1RA prior to the foot-shock prevented the diet-induced memory disruption, suggesting a critical role for IL-1ß in this phenomenon. Additionally, obese animals whose diet regimen was reversed from HFD back to standard chow recovered memory function and did not demonstrate a foot-shock-induced hippocampal IL-1ß increase. Interestingly, dietary reversal neutralized the negative impact of HFD on memory and IL-1ß, yet animals maintained physiological evidence of obesity (increased body mass and serum leptin), indicating that dietary components, not body mass, may mediate the negative effects on memory.
