Interleukin 21 promotes IgG1+ plasma cell differentiation instead of class switching to IgE via Blimp1 expression.

IgE is induced by the presence of IL-4 by class switching from IgM through IgG1 to IgE. IL-21 inhibits the IgE class switch by induction of Blimp1 leading to Stat6 and AID downregulation, and plasmablast/plasma cell differentiation.

Combination of plasma MMPs and PD-1-binding soluble PD-L1 predicts recurrence in gastric cancer and the efficacy of immune checkpoint inhibitors in non-small cell lung cancer.

Background: The tumor microenvironment (TME) impacts the therapeutic efficacy of immune checkpoint inhibitors (ICIs). No liquid biomarkers are available to evaluate TME heterogeneity. Here, we investigated the clinical significance of PD-1-binding soluble PD-L1 (bsPD-L1) in gastric cancer (GC) patients and non-small cell lung cancer (NSCLC) patients treated with PD-1/PD-L1 blockade. Methods: We examined bsPD-L1, matrix metalloproteinases (MMPs), and IFN-γ levels in plasma samples from GC patients (n = 117) prior to surgery and NSCLC patients (n = 72) prior to and 2 months after ICI treatment. We also examined extracellular matrix (ECM) integrity, PD-L1 expression, and T cell infiltration in tumor tissues from 25 GC patients by Elastica Masson-Goldner staining and immunohistochemical staining for PD-L1 and CD3, respectively. Results: bsPD-L1 was detected in 17/117 GC patients and 16/72 NSCLC patients. bsPD-L1 showed strong or moderate correlations with plasma MMP13 or MMP3 levels, respectively, in both GC and NSCLC patients. bsPD-L1 expression in GC was associated with IFN-γ levels and intra-tumoral T cell infiltration, whereas MMP13 levels were associated with loss of ECM integrity, allowing tumor cells to access blood vessels. Plasma MMP3 and MMP13 levels were altered during ICI treatment. Combined bsPD-L1 and MMP status had higher predictive accuracy to identify two patient groups with favorable and poor prognosis than tumor PD-L1 expression: bsPD-L1+MMP13high in GC and bsPD-L1+(MMP3 and MMP13)increased in NSCLC were associated with poor prognosis, whereas bsPD-L1+MMP13low in GC and bsPD-L1+(MMP3 or MMP13)decreased in NSCLC were associated with favorable prognosis. Conclusion: Plasma bsPD-L1 and MMP13 levels indicate T cell response and loss of ECM integrity, respectively, in the TME. The combination of bsPD-L1 and MMPs may represent a non-invasive tool to predict recurrence in GC and the efficacy of ICIs in NSCLC.

Lysosomal degradation of PD-L1 is associated with immune-related adverse events during anti-PD-L1 immunotherapy in NSCLC patients.

Background: Immune checkpoint inhibitors (ICIs) can induce immune-related adverse events (irAEs). Liquid biomarkers to predict irAE occurrence are urgently needed. We previously developed an ELISA system to specifically detect soluble PD-L1 (sPD-L1) with PD-1-binding capacity (bsPD-L1). Here, we investigated the relationship between sPD-L1 and bsPD-L1 in gastric cancer (GC) and non-small cell lung cancer (NSCLC) treated with PD-1/PD-L1 blockade and their association with irAEs. Methods: We examined sPD-L1, bsPD-L1, matrix metalloproteinases (MMPs), and proinflammatory cytokine levels by ELISA in plasma samples from 117 GC patients prior to surgery and 72 NSCLC patients prior to and at 2 months after ICI treatment (anti-PD-1, n = 48; anti-PD-L1, n = 24). In mice treated with anti-PD-1/PD-L1 antibodies (Abs), sPD-L1 levels and localization of Abs were examined by ELISA and immunohistochemistry, respectively. Results:sPD-L1 was detected with higher frequency in GC patients than in NSCLC patients, whereas bsPD-L1 was detected with similar frequencies in GC and NSCLC patients. sPD-L1 levels were correlated with IL-1α, IL-1ß, TNF-α, and IL-6 levels, while bsPD-L1 levels were correlated with MMP13, MMP3, and IFN-γ levels. In NSCLC patients, anti-PD-L1, but not anti-PD-1, treatment increased sPD-L1, which was associated with irAE development, but not with clinical outcomes. In mice, trafficking of anti-PD-L1 Abs to lysosomes in F4/80+ macrophages resulted in sPD-L1 production, which was suppressed by treatment with lysosomal degradation inhibitor chloroquine and macrophage depletion. Conclusion: Anti-PD-L1-mediated lysosomal degradation induces sPD-L1 production, which can serve as an indicator to predict irAE development during anti-PD-L1 treatment.

National Survey of Oncologists' Knowledge, Attitudes, and Practice Behaviors: Caring for Cancer Patients Experiencing Incarceration.

Cancer is the leading cause of illness-related death in state prisons in the United States. The experiences of physicians providing oncological care to individuals experiencing incarceration are underexplored. The study aims were to evaluate knowledge, attitudes, and practices of oncologists caring for cancer patients who are incarcerated. An online survey was distributed to a random sample of 150 oncologists from the American Society of Clinical Oncology and the American Society for Radiation Oncology from July 2020 to December 2021. Statistical analyses included two proportion Z-test, Fisher's exact test, Kruskal-Wallis test, and Cramer's V to estimate factors associated with attitudes and barriers to care. Of the 55 respondents (36.7% response rate), 21 were medical oncologists and 34 were radiation oncologists. Academic center oncologists were more likely to report caring for incarcerated patients than community or private practice oncologists (p = .04). Most (53%) incorrectly reported "heart disease" as the leading cause of death, as opposed to "cancer" (15% identified correctly). Oncologists practicing at both academic and community centers were more likely to report care coordination barriers than oncologists at academic or community centers (p < .01). We identified potential barriers in caring for incarcerated cancer patients. Future studies should explore ways to improve care coordination between oncology teams and prisons.

Perceived Pager Burden Among Trainees Across Medical Specialties.

BACKGROUND: The experiences of pager use among trainees across medical specialties is underexplored. The aim of this study was to assess experiences of pager burden and communication preferences among trainees in different specialties. METHODS: An online survey was developed to assess perceived pager burden (eg, pager volume, mistake pages, sleep, and off-time interruptions) and communication preferences at a tertiary center in the United States. All residents and fellows were eligible to participate. Responses were grouped by specialty: General surgery [GS], Surgical subspecialty [SS], Medicine, Anesthesiology, and Psychiatry. Multivariable linear regression was used to assess factors associated with pager burden. Free text responses were analyzed using open coding methods. RESULTS: Of the total 306 responses, the majority were female (58.8%), 30-39 years (59.2%), and White (70.6%). Specialty breakdown was: Medicine (40.2%), Psychiatry (10.8%), SS (18.0%), GS (5.6%), and Anesthesiology (3.6%). GS respondents reported receiving more mistake pages (P < .001), spending more time redirecting mistake pages (P = .003), and having the highest sleep time disruptions (P < .001). For urgent communications, surgical trainees preferred physical pagers, while nonsurgical trainees preferred smartphone pagers (P = .001). "Receive fewer nonurgent pages" was the most common change respondents desired. DISCUSSION: In this single center study, subjective experiences of pager burden were disproportionately high among GS trainees. Reducing nonurgent and mistake pages are potential targets for improving trainee communication experiences. Hospitals should consider incorporating trainee preferences into paging systems. Additional studies are warranted to increase the sample size, assess generalizability of the findings, and contextualize trainee experiences with objective hospital-level paging data.

Integrating Navigation-Assisted Ablation in the Locoregional Treatment of Hepatocellular Carcinoma.

Importance: With the increasing prevalence of hepatocellular carcinoma (HCC), ablative therapy is a critical treatment option to achieve a cancer-free state. The anatomic location of the tumor can be a challenge, and select hepatic locations of a tumor require laparoscopic-assisted strategies to safely reach and treat the lesion. Objective: To assess the association of real-time ultrasonography-augmented navigation for HCC ablation with patient survival, operative time, and rate of incomplete ablations. Design, Setting, and Participants: This retrospective case-control study was conducted among a prospectively collected database of more than 750 patients with HCC who were treated with ablation therapy with and without the use of navigation at a single quaternary medical center from June 2011 to January 2021. Data were analyzed from October 2022 through June 2023. Exposure: Real-time ultrasonography-augmented navigation. Main Outcomes and Measures: The primary outcome was rate of incomplete ablations in patients undergoing HCC ablation with vs without navigation. Secondary outcomes included overall survival (OS), progression-free survival (PFS), and operative time. Results: The analytic cohort included 467 patients (mean [SD] age, 62.4 [7.8] years; 355 male [76.0%]; 21 Hispanic [4.5%], 67 non-Hispanic Black [14.5%], and 347 Non-Hispanic White [75.0%] among 463 patients with race and ethnicity data). The most common etiology of liver disease was hepatitis C infection (187 patients with etiology data [40.0%]), and 348 of 458 patients with TMN staging data (76.0%) had TNM stage 1 disease. There were 187 individuals treated with navigation and 280 individuals treated without navigation. Patients who underwent navigation-assisted ablation were more likely to have stage 2 disease based on TNM staging (62 of 183 patients [33.9%] vs 47 of 275 patients [17.1%] with TMN data; P < .002) and had a higher mean (SD) number of lesions (1.3 [0.5] vs 1.2 [0.5] lesions; P = .002) and a longer mean (SD) operation time (113.2 [29.4] vs 109.6 [32.3] minutes; P = .04). Patients who underwent navigation were also more likely to have tumors in segment 8 (59 patients [32.1%] vs 53 of 275 patients with segment data [19.3%] with segment data; P = .005) and less likely to have tumors in segment 4 (20 patients [10.9%] vs 54 patients with segment data [19.6%]; P = .005). Overall mean (SD) time to recurrence after treatment was 10.0 (12.5) months, with similar rates for patients with navigation vs no navigation. There were no differences in incomplete ablation rate (10 patients [9.2%] vs 10 patients [10.5%]; P = .32), OS, or PFS between patients undergoing ablation with and without navigation. Conclusions and Relevance: In this study, use of navigation was associated with comparable outcomes to undergoing ablation without navigation, although patients with navigation had more locally advanced disease. These findings suggest that use of real-time navigation in laparoscopic-assisted ablation of liver cancer should be considered as a useful tool for treating challenging tumors.

At the Intersection of Intersectionality: Race and Gender Diversity Among Surgical Faculty and Trainees.

OBJECTIVE: To compare the representation of intersectional (ie, racial/ethnic and gender) identities among surgical faculty versus medical students. BACKGROUND: Health disparities are pervasive in medicine, but diverse physicians may help the medical profession achieve health equity. METHODS: Data from the Association of American Medical Colleges for 140 programs (2011/2012-2019/2020) were analyzed for students and full-time surgical faculty. Underrepresented in medicine (URiM) was defined as Black/African American, American Indian/Alaskan Native, Hispanic/Latino/Spanish Origin, or Native Hawaiian/Other Pacific Islander. Non-White included URiM plus Asian, multiracial, and non-citizen permanent residents. Linear regression was used to estimate the association of year and proportions of URiM and non-White female and male faculty with proportions of URiM and non-White students. RESULTS: Medical students were comprised of more White (25.2% vs 14.4%), non-White (18.8% vs 6.6%), and URiM (9.6% vs 2.8%) women and concomitantly fewer men across all groups versus faculty (all P < 0.01). Although the proportion of White and non-White female faculty increased over time (both P ≤ 0.001), there was no significant change among non-White URiM female faculty, nor among non-White male faculty, regardless of whether they were URiM or not. Having more URiM male faculty was associated with having more non-White female students (estimate = +14.5% students/100% increase in faculty, 95% CI: 1.0% to 8.1%, P = 0.04), and this association was especially pronounced for URiM female students (estimate = +46.6% students/100% increase in faculty, 95% CI: 36.9% to 56.3%, P < 0.001). CONCLUSIONS: URiM faculty representation has not improved despite a positive association between having more URiM male faculty and having more diverse students.

Persistent underuse of extended venous thromboembolism prophylaxis in patients undergoing major abdominal cancer operations.

BACKGROUND: Guidelines recommend extended venous thromboembolism (VTE) prophylaxis for high-risk populations undergoing major abdominal cancer operations. Few studies have evaluated extended VTE prophylaxis in the Medicare population who are at higher risk due to age. METHODS: We performed a retrospective study using a 20% random sample of Medicare claims, 2012-2017. Patients ≥65 years with an abdominal cancer undergoing resection were included. Primary outcome was the proportion of patients receiving new extended VTE prophylaxis prescriptions at discharge. Secondary outcomes included postdischarge VTE and hemorrhagic events. RESULTS: The study included 72 983 patients with a mean age of 75. Overall, 8.9% of patients received extended VTE prophylaxis. This proportion increased (7.2% in 2012, 10.6% in 2017; p < 0.001). Incidence of postdischarge hemorrhagic events was 1.0% in patients receiving extended VTE prophylaxis and 0.8% in those who did not. The incidence of postdischarge VTE events was 5.2% in patients receiving extended VTE prophylaxis and 2.4% in those who did not. CONCLUSION: Adherence to guideline-recommended extended VTE prophylaxis in high-risk patients undergoing major abdominal cancer operations is low. The higher rate of VTE in the prophylaxis group may suggest we captured some therapeutic anticoagulation, which would mean the actual rate of thromboprophylaxis is lower than reported herein.

Breast Cancer Germline Genetic Counseling and Testing for Populations of African Heritage Globally: A Scoping Review on Research, Practice, and Bioethical Considerations.

PURPOSE: Despite the disproportionately high risk of breast cancer among women of African heritage, little is known about the facilitators and barriers to implementing germline genetic testing and counseling (GT/C). METHODS: This scoping review followed guidelines recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. Published manuscripts from database inception through 2021 were sourced from PubMed, Cumulative Index to Nursing and Allied Health Literature via EBSCO, Embase, Cochrane Library, and Scopus. Search terms were used to retrieve articles addressing (1) African heritage, (2) breast cancer, and (3) GT or GC. The screening involved abstract and title review and full-text review. Data were extracted for all articles meeting the inclusion criteria. RESULTS: A total of 154 studies were included. Most studies that took place were conducted in the United States (71.4%), and most first authors (76.9%) were from the United States. GT was conducted in 73 (49.7%) studies. BRCA1/BRCA2 were the most commonly studied genes for germline mutations. GC was conducted in 49 studies (33.3%), and perspectives on GC were evaluated in 43 (29.3%). The use of racial/ethnic categories varied broadly, although African American was most common (40.1%). Racism was mentioned in three studies (2.0%). CONCLUSION: There is a growing body of literature on GT/C for breast cancer in women of African heritage. Future studies on GT/C of African populations should consider increased clarity around racial/ethnic categorizations, continued community engagement, and intentional processes for informed consent.

Racial, Ethnic, and Gender Diversity Among Academic Surgical Leaders in the US.

Importance: Surgical department chairs remain conspicuously nondiverse despite the recognized importance of diverse physician workforces. However, the extent of diversity among non-chair leadership remains underexplored. Objective: To evaluate racial, ethnic, and gender diversity of surgical department chairs, vice chairs (VCs), and division chiefs (DCs) in the US. Design, Setting, and Participants: For this cross-sectional study, publicly accessible medical school and affiliated hospital websites in the US and Puerto Rico were searched from January 15 to July 15, 2022, to collect demographic and leadership data about surgical faculty. Two independent reviewers abstracted demographic data, with up to 2 additional reviewers assisting with coding resolution as necessary. In all, 2165 faculty were included in the analyses. Main Outcomes and Measures: Proportions of racial, ethnic, and gender diversity among chairs, VCs, and DCs in general surgery and 5 surgical specialties (neurosurgery, obstetrics and gynecology, ophthalmology, orthopedics, and otolaryngology). Results: A total of 2165 faculty (1815 males [83.8%] and 350 females [16.2%]; 109 [5.0%] African American or Black individuals; 347 [16.0%] Asian individuals; 83 [3.8%] Hispanic, Latino, or individuals of Spanish origin; and 1624 [75.0%] White individuals as well as 2 individuals [0.1%] of other race or ethnicity) at 154 surgical departments affiliated with 146 medical schools in the US and Puerto Rico were included in the analysis. There were more males than females in leadership positions at all levels-chairs (85.9% vs 14.1%), VCs (68.4% vs 31.6%), and DCs (87.1% vs 12.9%)-and only 192 leaders (8.9%) were from racial or ethnic groups that are underrepresented in medicine (URiM). Females occupied more VC than chair or DC positions both overall (31.6% vs 14.1% and 12.9%, respectively) and within racial and ethnic groups (African American or Black females, 4.0% VC vs 1.5% chair and 0.6% DC positions; P < .001). URiM individuals were most commonly VCs of diversity, equity, and inclusion (DEI, 51.6%) or faculty development (17.9%). Vice chairs of faculty development were split equally between males and females, while 64.5% of VCs for DEI were female. All other VCs were predominantly male. Among DC roles, URiM representation was greatest in transplant surgery (13.8%) and lowest in oral and maxillofacial surgery (5.0%). Except for breast and endocrine surgery (63.6% female), females comprised less than 20% of DC roles. Nearly half of DCs (6 of 13 [46.2%]) and VCs (4 of 9 [44.4%]) had no female URiM leaders, and notably, no American Indian, Alaska Native, or Native Hawaiian or Other Pacific Islander individuals were identified in any surgical leadership positions. Conclusions and Relevance: While it is unclear whether promotion from VC to chair or from DC to chair is more likely, these findings of similar gender distribution between chairs and DCs suggest the latter and may partially explain persistent nondiversity among surgical chairs. Female and URiM surgical leaders are disproportionately clustered in roles (eg, VCs of DEI or faculty development) that may not translate into future promotion to department chairs.

Death in Prison: increasing transparency on next of kin notification and disposition of remains.

BACKGROUND: Policies for next-of-kin (NOK) notification and disposition of remains surrounding death are unclear across the United States' (US) carceral systems. The goal of this study was to collect data on carceral system policies pertaining to NOK notification and disposition of remains for individuals who are incarcerated. We collected publicly available operational policies for the Federal Bureau of Prisons, Immigration and Customs Enforcement, 50 state prison systems, and the Washington D.C. jail for a total of 53 systems. RESULTS: Approximately 70% of systems had available policies on NOK notification and disposition of remains. Few systems had information on time constraints for NOK notification, notifying parties or designated contacts person, and ultimate disposition of unclaimed remains. Several systems had no accessible policies. CONCLUSIONS: Across the US, carceral systems vary in policies for notifying NOK after the death of an incarcerated individual and their processes for the disposition of remains. Carceral and health systems should work towards standardization of policies on communication and disposition of remains after death of an individual who is incarcerated to work towards equity.

Survey Study of Clerkship Curriculum on Learner's Choice to Pursue Surgery: Positive Impact of Extracurricular Opportunities.

OBJECTIVE: Prior studies have focused on the role of the learning environment on students' decisions to pursue surgery, but few have analyzed the impact of the clerkship curriculum. This study assessed surgical clerkship curricula across United States (US) medical schools and their impact on students' likelihood of pursuing a surgical residency. DESIGN: A cross-sectional survey was developed to assess surgery clerkship characteristics. Questions included clerkship duration, number of offered and required surgical services, method of service assignment, and number of advanced clinical electives (e.g., fourth-year sub-internships) and additional surgical clinical opportunities (e.g., surgical elective rotations). Survey results were merged by the Association of American Medical Colleges with the percentages of students who matched into a surgical specialty. Linear regression models estimated the association of covariates with the percentage of students who (1) matched in surgical specialties, (2) were interested in surgery at medical school matriculation and ultimately matched into surgical residency (retention rate), and (3) were not interested in surgery at medical school matriculation but ultimately matched into surgical residency (recruitment rate). SETTING: The survey was distributed to clerkship directors and coordinators at 66 medical schools through the Association for Surgical Education (ASE) from 5/1/2021 to 8/1/2021. PARTICIPANTS: All US medical schools in the ASE. RESULTS: A total of 21 medical schools responded (34.8% response rate). The overall retention rate was 36.4%, and the overall recruitment rate was 25.0%. Clerkships were 4 to 12 weeks. In 81% of programs, students submitted preferences and were assigned services. The percentage of students applying to surgical specialties was not associated with clerkship duration (p=0.79) or the number of required services (p=0.15), subspecialty services offered (p=0.33), or advanced clinical electives (p=0.24) but was associated with a program's having additional surgical clinical opportunities (p=0.02). Most of these factors were not associated with retention or recruitment rates. CONCLUSIONS: Offering more extracurricular surgical clinical opportunities was associated with having more students pursue surgical careers. Though limited by a relatively small sample size, our findings suggest that having shorter clerkships or limited subspecialty offerings may not have a significant influence on students' career choices.

Fractured and delayed: A qualitative analysis of disruptions in care for gynecologic malignancies during incarceration.

OBJECTIVE: Women are experiencing growing rates of incarceration at twice the pace of that for men. Additionally, one-third will be older than 55 years of age by the end of the decade. Women who are incarcerated experience a higher prevalence of gynecologic malignancies and present with higher stage disease, which may be contributing to the greater mortality from cancer than the age-adjusted US population. Limited access to guideline-recommended screening and prevention and resource limitations across correctional facilities may result in gynecologic cancer disparities. Reasons for delayed gynecologic cancer care in prisons remain underexplored. Therefore, we sought to identify contributors to delayed gynecologic cancer care among women experiencing incarceration. METHODS: Women at a single tertiary center in the Southeastern U.S. who were incarcerated and were diagnosed with a gynecologic cancer during 2014-2021 were identified in the electronic medical record. Note text was extracted and contributors to delay were identified and categorized using the RADaR method. Descriptive statistics were used to assess quantitative data. RESULTS: 14 patients were identified with a total of 14,879 text excerpts. Data reduction was performed to identify excerpts that were relevant to the central research question resulting in 175 relevant note excerpts. Delays prior to the tertiary care visit included patient and institutional contributors. Delays during transition from the tertiary center to prison included discharge planning and loss to follow-up during/after incarceration. Transportation, authorization, and restraints were concrete contributors. Abstract contributors included communication, and the patient's emotional experience. CONCLUSIONS: We identify myriad contributors to delayed or fractured gynecologic cancer care in women experiencing incarceration. The impact of these issues warrants further study and intervention to improve care.

Leadership and Impostor Syndrome in Surgery.

BACKGROUND: Impostor syndrome is an internalized sense of incompetence and not belonging. We examined associations between impostor syndrome and holding leadership positions in medicine. STUDY DESIGN: A cross-sectional survey was distributed to US physicians from June 2021 to December 2021 through medical schools and professional organizations. Differences were tested with the chi-square test and t -test for categorical and continuous variables, respectively. Logistic regression was used to identify factors associated with holding leadership positions and experiencing impostor syndrome. RESULTS: A total of 2,183 attending and retired physicians were included in the analytic cohort; 1,471 (67.4%) were in leadership roles and 712 (32.6%) were not. After adjustment, male physicians were more likely than women to hold leadership positions (odds ratio 1.4; 95% CI 1.16 to 1.69; p < 0.001). Non-US citizens (permanent resident or visa holder) were less likely to hold leadership positions than US citizens (odds ratio 0.3; 95% CI 0.16 to 0.55; p < 0.001). Having a leadership position was associated with lower odds of impostor syndrome (odds ratio 0.54; 95% CI 0.43 to 0.68; p < 0.001). Female surgeons were more likely to report impostor syndrome compared to male surgeons (90.0% vs 67.7%; p < 0.001), an association that persisted even when female surgeons held leadership roles. Similar trends were appreciated for female and male nonsurgeons. Impostor syndrome rates did not differ by race and ethnicity, including among those underrepresented in medicine, even after adjustment for gender and leadership role. CONCLUSIONS: Female physicians were more likely to experience impostor syndrome than men, regardless of specialty or leadership role. Although several identity-based gaps persist in leadership, impostor syndrome among racially minoritized groups may not be a significant contributor.

US Prison Policies on Organ Donation for Individuals Who Are Incarcerated.

This cross-sectional study collects data on US prison policies concerning organ donation by incarcerated individuals.

Supporting DACA recipients and international students pursuing careers in medicine: A pilot program for advisors.

The United States (U.S.) health professions are becoming more invested in diversity. Information on students who are undocumented or recipients of Deferred Action for Childhood Arrivals (DACA), and international students on student visas entering U.S. medical education is sparse. Few programs offer targeted training for educators on advising students who are undocumented, DACA recipients, or on a visa. We piloted a virtual program for pre-health advisors and educators on supporting students who are undocumented or recipients of DACA and international students transitioning to medical school. Program evaluation consisted of an anonymous retrospective pre-post survey. Of 117 registrants, 40% completed the survey. Prior to the program, most participants indicated that they were unsure or thought students were ineligible for financial aid during medical school if they were DACA recipients (40% unsure, 26.6% ineligible) or on a student visa (30% unsure, 30% ineligible). After the program, most respondents reported students were eligible for merit scholarship or private loans with DACA (66.6% eligible) or an international student visa (60% eligible). Perceptions of students with DACA being able to lawfully practice medicine in the U.S. changed from pre-program (43.3% unsure or not eligible) to post-program (90% eligible). Participants indicated they were more confident advising DACA recipients and international students post program. This virtual program was an effective step in providing support for advisors who are assisting non-citizen or permanent resident students start their careers in healthcare. Our findings show the need for more information on advising students who are DACA recipients, undocumented, or on student visas prior to matriculating to medical school and throughout training.

A Novel Narrative Medicine Approach to DEI Training for Medical School Faculty.

Problem:Diversity, Equity, and Inclusion (DEI) trainings for medical school faculty often lack self-reflective and pedagogically focused components that may promote incorporation of anti-racism and social justice into medical school curricula. Intervention: A four-session Narrative Medicine (NM) anti-racism program was designed for medical school faculty using critical race theory, phenomenology, and NM methods. Each workshop consisted of a lecture on key NM concepts and a small-group breakout session incorporating group discussion, close reading, and reflective writing. Context: This NM anti-racism program was developed and implemented in April 2021 by two medical students for faculty at an institution in the southeastern U.S. The program was supported by the Office of Inclusive Excellence at the institution and held in collaboration with the institution's medical education teaching academy. Program evaluation consisted of pre- and post-program surveys, which queried participants' previous experiences with DEI and medical humanities programs, perceptions of self-identity and privilege, and confidence in teaching concepts of anti-racism. Of the total program participants (n = 32), 19 completed both surveys (54.3%). Survey data were analyzed using bivariate testing methods and qualitative thematic analysis. Impact: Post-program surveys showed 13 (68.4%) participants felt "somewhat more" or "more" comfortable engaging in concepts of race, and 12 (63.2%) participants felt "somewhat more" or "more" comfortable including topics of race into their teaching compared to before the program. Five themes were generated following qualitative analysis: (1) the value of longitudinal narrative reflection in a small-group setting for DEI work; (2) desire to commit more time to DEI, anti-racist, and social justice work while balancing busy teaching and clinical schedules; (3) the value of storytelling in DEI and anti-racism programming; (4) an understanding of deconstructive and reconstructive work of anti-racism in medicine; and (5) an increased ability to educate and enact change through teaching, activism, and institutional cultural and policy changes. Lessons Learned: This novel NM DEI training for medical school faculty was successful in increasing comfort discussing and teaching concepts of race in the medical school classroom, while providing a uniquely reflective space for personal growth. Participation in this longitudinal reflective experience was limited by physician schedules, therefore efforts to make time to participate in similar longitudinal interventions must be undertaken.

Indocyanine Green as a Navigational Adjunct for Laparoscopic Ablation of Liver Tumors.

BACKGROUND: Minimally invasive operative approaches for resection and thermal ablation (eg, microwave, radiofrequency) of hepatocellular carcinoma (HCC) have been successfully implemented over the last two decades, although identifying tumors can be challenging. Successfully performing laparoscopic ablation requires real-time visualization and ultrasonography skills for direct placement of the ablation probe. METHODS: In this study, we introduce a novel adjunct to ultrasound imaging for tumors located near or on the surface of the liver via intravenous delivery of indocyanine green (ICG) dye. Non-resectable lesion(s) not amenable to percutaneous ablation were considered for laparoscopic microwave ablation. Each patient initially received a dose of .3125 mg ICG via peripheral IV. RESULTS: A total of 17 patients were included. There was brisk uptake of ICG throughout the liver parenchyma in under 2 minutes in 15 of 17 patients; the remaining 2 required a second dose of ICG. In 14 cases, a hypo-fluorescent perfusion pattern in the tumor was clearly identified. DISCUSSION: Integrating ICG and fluorescent imaging provides a complementary adjunct to ultrasound in identifying HCC nodules. While previous applications of ICG typically require injections several days prior to surgery or segmental injections, this study demonstrates a novel real-time application of ICG to aid surgeons with various experiences in laparoscopic-assisted ablation procedures for HCC.

Shaves off the Cavity or Specimen in Lumpectomy for Breast Cancer.

INTRODUCTION: Re-excision for positive margins (margins where tumor is positive) after breast conserving surgery (BCS) is common and burdensome for breast cancer patients. Routine shave margins can reduce positive margins and re-excision rates. Cavity shaving margin (CSM) removes margins from the lumpectomy cavity edges, whereas specimen shave margin (SSM) requires ex vivo removal of margins from the resected specimen. METHODS: We assessed breast cancer patients undergoing BCS who received CSM or SSM procedures from 2017 to 2019. CSM and SSM techniques were compared by analyzing positive rates of primary and final shaved margins, re-excision rates, and tissue volumes removed. RESULTS: Of 116 patients included in this study, 57 underwent CSM and 59 underwent SSM. Primary margins were positive or close in 19 CSM patients and 21 SSM patients (33% versus 36%; P = 0.798). Seventeen CSM patients had a tumor in shaved margin specimens, compared to four patients for SSM (30% versus 7%; P < 0.001); however, final shave margins were similar (5% versus 5%; P = 0.983). Volumes of shave specimens were higher with SSM (40.7 versus 13.4 cm3; P < 0.001), but there was no significant difference in the total volume removed (146.8 versus 134.4 cm3; P = 0.540). For tumors 2 cm or larger, the total volume removed (140 versus 206 cm3; P = 0.432) and rates of final margin positivity (7.5% versus 0%; P = 0.684) were similar for both techniques. CONCLUSIONS: CSM and SSM are effective techniques for achieving low re-excision rates. Our findings suggest that surgeons performing either CSM or SSM may maintain operative preferences and achieve similar results.
