RESUMEN

The University of Alabama at Birmingham Heersink School of Medicine established the Pittman Scholars Program in 2015 to elevate scientific impact and to support the recruitment and retention of highly competitive junior faculty. The authors examined the impact of this program on research productivity and on faculty retention. The authors evaluated publications and extramural grant awards and available demographic data for the Pittman Scholars compared to all junior faculty in the Heersink School of Medicine. From 2015 to 2021, the program awarded a diverse group of 41 junior faculty members across the institution. For this cohort, ninety-four new extramural grants were awarded and 146 grant applications were submitted since the inception of the scholar award. Pittman Scholars published a total of 411 papers during the term of the award. The faculty retention rate of the scholars was 95%, comparable to that of all Heersink junior faculty, with 2 recipients being recruited to other institutions. The implementation of the Pittman Scholars Program has been an effective strategy to celebrate scientific impact and acknowledge junior faculty members as outstanding scientists at our institution. The Pittman Scholars award allows junior faculty to use funds for their research program, publications, collaborations, and career advancement. The Pittman Scholars are recognized at local, regional, and national levels for the work they are contributing to academic medicine. The program has served as an important pipeline faculty development program and an avenue for individual recognition for research-intensive faculty.

RESUMEN

INTRODUCTION: Drain fluid amylase (DFA) levels have been used to predict clinically relevant postoperative pancreatic fistula (CR-POPF) and guide postoperative drain management. Optimal DFA cutoff thresholds vary between studies, thereby prompting investigation of an alternative assessment technique. As DFA measurements could, in theory, be distorted by variations in ascites fluid production, we hypothesized that adjusting DFA for volume corrected drain fluid amylase (vDFA) would improve CR-POPF predictive models. METHODS: A single-institution retrospective cohort study of patients, who underwent pancreatoduodenectomies (PD) and distal pancreatectomies (DP) between 2013 and 2019, was performed. DFAs and vDFAs were measured on postoperative day (POD) 3. Clinicopathologic variables were compared between cohorts by univariable and multivariable analyses and Receiver operating characteristic (ROC) curves. RESULTS: Patients developing a CR-POPF were more likely to be male and have elevated DFA, vDFA, and body mass index (BMI). vDFA use did not contribute to a superior CR-POPF predictive model compared to DFA-a finding consistent on subanalysis of surgery type PD versus DP. In CR-POPF predictive models, DFA, vDFA, and male sex significantly improved CR-POPF predictive models when considering both surgery subtypes, while only DFA and vDFA significantly improved models when cohorts were segregated by surgery type. CONCLUSIONS: Postoperative DFA remains a preferred method of predicting CR-POPF as the proposed vDFA assessment technique only adds complexity without increased discriminability.

RESUMEN

INTRODUCTION: Despite aggressive surgical care and systemic therapy, patients with pancreatic ductal adenocarcinoma (PDAC) have a poor prognosis. Recent studies show that racial disparities in outcome also exist. We sought to investigate the association lymph node (LN) metastases had with survival between Black and White patients with PDAC after resection. METHODS: Retrospective analysis of 226 PDAC patients who underwent resection at a single institution from 2010 to 2018 was performed with attention to LN metastasis and patient race. The number of patients who received chemotherapy was also evaluated. RESULTS: One Hundred Seventy Five (77.4%) PDAC patients were White and 51 (22.6%) were Black. 130 (59.3%) patients had LN metastasis (LN+). LN+ and LN- groups were similar in race (P = 0.93), sex (P = 0.10) and age at the time of diagnosis (P = 0.45). Patients with LN + disease were more likely to present with larger tumors (3.4 versus 2.8 cm, P = 0.02) and higher T status (P = 0.001). White and Black patients had similar rates of LN metastasis (59% versus 58.8%, P = 1.0). The median survival for LN- Black and White patients were similar (43.2 versus 30.2 mo, P = 0.82). LN + Black patients trended towards receiving more systemic therapy than White LN + patients (55% versus 42%, P = 0.10). The median survival for LN + Black patients was significantly less than LN + White patients (17.5 versus 24.6 mo, P = 0.04). CONCLUSIONS: Black LN + PDAC patients have an inferior survival rate after resection when compared to their White counterparts. Our disparity in outcome cannot be solely explained by a difference in systemic treatment. Further investigation is warranted to determine racial differences in tumor biology or response to chemotherapy.

RESUMEN

BACKGROUND: Systemic therapy is a key management component of pancreatic ductal adenocarcinoma(PDAC). Racial disparities exist in PDAC, often linked to socioeconomic variables. We investigated the impact of race in PDAC patients who had undergone systemic therapy and surgical resection. METHODS: A retrospective analysis was performed for all patients who underwent surgical resection for PDAC from 2010 to 2018. RESULTS: 234 patients (78.2% White; 21.8% Black) were included. Black patients presented at a younger age with larger tumors. White patients benefited from systemic therapy with longer overall survival (35vs20 months, p = 0.002). This survival advantage was not present in Black patients (21vs15 months, p = 0.15). Black patients receiving systemic therapy had similar survival as White patients who did not (p = 0.81). CONCLUSION: Black PDAC patients present at younger ages and with larger initial tumors. In our population, White patients had a longer overall survival after both surgical and systemic therapy. These findings may indicate differences in tumor biology. Further prospective studies are needed.

RESUMEN

BACKGROUND: Fistula Risk Score (FRS) models often lack adequate discrimination for clinically relevant postoperative pancreatic fistula (CR-POPF) on external validation. We tested four FRS models in the Deep South United States and sought to determine if CR-POPF discrimination was affected by racial disparities. METHODS: A single-institution retrospective cohort study of patients who underwent pancreatoduodenectomies between 2013 and 2019 was performed. FRS discrimination for CR-POPF was assessed using ROC curves for both the entire patient population, and for Black vs White patients. RESULTS: The Alternative FRS maintains adequate CR-POPF discrimination when considering the patient population as a whole, but inadequately predicts CR-POPF when applied to the Black patient population. The Sun-FRS provides adequate CR-POPF discrimination for Black patients when considering risk grade. Only soft pancreatic gland texture and small duct size were significantly associated with CR-POPF in this patient population. DISCUSSION: Institutions should assess their preferred FRS model to determine if it provides adequate CR-POPF discrimination among a racially diverse patient population. Further studies are needed to determine how racial disparities influence CR-POPF prediction to better guide postoperative management.

RESUMEN

OBJECTIVES: Pancreatic cancer continues to be a major cause of cancer-related mortality. There has been a greater implementation of up-front chemotherapy for pancreatic adenocarcinoma patients. Although there are many theoretical benefits to neoadjuvant chemotherapy, its clinical impact is uncertain. We sought to understand the outcomes of patients with resectable and borderline-resectable pancreatic adenocarcinoma who underwent neoadjuvant chemotherapy. METHODS: Patients were collected in a secure database from September 2018 to May 2020. Patients were excluded if they presented with locally advanced or metastatic disease, inability to complete chemotherapy, or if they were not a surgical candidate. RESULTS: Sixty-six patients with resectable disease underwent chemotherapy. Folinic acid/5-fluorouracil/irinotecan/oxaliplatin was used in 41 patients (62.1%) and gemcitabine-based regimens in 28 patients (42.4%, greater than 100% as some patients underwent both regimens). After restaging, 47 patients (71.2%) were thought to have resectable disease. Of these patients, 36 have been successfully resected to date. Metastatic disease was found in 12 patients (18.2%) and 6 patients (9.1%) had locally advanced disease. CONCLUSIONS: Most patients with resectable pancreatic cancer are resected after neoadjuvant chemotherapy, but a subset will develop local or distant progression. Further studies will be needed to determine which patients will progress locally and may benefit from an up-front surgical approach.

RESUMEN

PURPOSE: In general, participation rates in cancer clinical trials are very low. However, participation rates are especially low among the socially disadvantaged and racial and ethnic minority groups. These groups have been historically under-represented in cancer clinical trials. Although many patient-related barriers have been studied, institutional factors that are essential for building clinical research infrastructure around the clinical trial enterprise in academic medical centers have been underexplored. MATERIALS AND METHODS: We assessed perspectives of cancer center professional stakeholders on the institutional factors that can potentially influence racial and ethnic minority recruitment for cancer clinical trials. Ninety-one qualitative interviews were conducted at five US cancer centers among four stakeholder groups: cancer center leaders, principal investigators, referring clinicians, and research staff. Qualitative analyses examined response data focused on institutional factors related to minority recruitment for cancer clinical trials. RESULTS: Four prominent themes emerged regarding institutional barriers among clinical and research professionals. (1) There are no existing programs currently being used to recruit or retain minorities to clinical trials. (2) Institutional efforts are needed to increase trial participation and are not specific to potential minority participants. (3) Access to cancer clinical trials and navigation within an Academic Medical Center need to be simplified to better facilitate recruitment of minority patients. (4) Community outreach by cancer centers will increase clinical research awareness in the community. CONCLUSION: Our research highlights the need to address institutional barriers to improve the success of minority recruitment. To increase participation among minority populations, medical centers must address mutable institutional barriers such as setting specific minority recruitment goals for cancer clinical trials, ensuring that cancer clinical trials are accessible, especially to minority patients, and supporting sustained community outreach programs to increase clinical research awareness.

RESUMEN

The University of Alabama at Birmingham academic medical center (UAB AMC) had achieved great success and growth during the 50 years since its founding. However, the challenging and more competitive environment of the 2000s left the UAB AMC on a downward trajectory. The UAB AMC had to overcome difficult internal cultural and structural barriers that stood in the way of the transformational change needed to remain competitive. Competition rather than collaborative and strategic financial investment were the primary cultural barriers for the UAB AMC, while people were the primary structural barrier. Leadership identified 5 steps that were critical for the transformation that occurred between 2013 and 2018: alignment of leadership; creating a compelling and credible shared vision; identifying cultural and structural barriers; creating a thoughtful, data-driven intervention; and improved communication and accountability. Following these steps enabled the UAB AMC to transform its institutional structure and culture. As a result, the UAB AMC thrived, returning to substantial growth in research and clinical care. UAB AMC School of Medicine grew by $100 million in National Institutes of Health funding and moved up 10 spots in ranking. In 2018, UAB Hospital had 10 specialties ranked by U.S. News & World Report, 7 more than in 2013. This article outlines the approach taken and provides a conceptual framework for other AMCs eager to transform their structure and culture and position themselves for growth.

RESUMEN

Heart failure (HF) is a multifactorial syndrome that remains a leading cause of worldwide morbidity. Despite its high prevalence, only half of patients with HF respond to guideline-directed medical management, prompting therapeutic efforts to confront the molecular underpinnings of its heterogeneity. In the current study, we examined epigenetics as a yet unexplored source of heterogeneity among patients with end-stage HF. Specifically, a multicohort-based study was designed to quantify cardiac genome-wide cytosine-p-guanine (CpG) methylation of cardiac biopsies from male patients undergoing left ventricular assist device (LVAD) implantation. In both pilot (n = 11) and testing (n = 31) cohorts, unsupervised multidimensional scaling of genome-wide myocardial DNA methylation exhibited a bimodal distribution of CpG methylation found largely to occur in the promoter regions of metabolic genes. Among the available patient attributes, only categorical self-identified patient race could delineate this methylation signature, with African American (AA) and Caucasian American (CA) samples clustering separately. Because race is a social construct, and thus a poor proxy of human physiology, extensive review of medical records was conducted, but ultimately failed to identify covariates of race at the time of LVAD surgery. By contrast, retrospective analysis exposed a higher all-cause mortality among AA (56.3%) relative to CA (16.7%) patients at 2 yr following LVAD placement (P = 0.03). Geocoding-based approximation of patient demographics uncovered disparities in income levels among AA relative to CA patients. Although additional studies are needed, the current analysis implicates cardiac DNA methylation as a previously unrecognized indicator of socioeconomic disparity in human heart failure outcomes.NEW & NOTEWORTHY A bimodal signature of cardiac DNA methylation in heart failure corresponds with racial differences in all-cause mortality following mechanical circulatory support. Racial differences in promoter methylation disproportionately affect metabolic signaling pathways. Socioeconomic factors are associated with racial differences in the cardiac methylome among men with end-stage heart failure.

RESUMEN

The past decade has witnessed groundbreaking advances in the field of microbiome research. An area where immense implications of the microbiome have been demonstrated is tumor biology. The microbiome affects tumor initiation and progression through direct effects on the tumor cells and indirectly through manipulation of the immune system. It can also determine response to cancer therapies and predict disease progression and survival. Modulation of the microbiome can be harnessed to potentiate the efficacy of immunotherapies and decrease their toxicity. In this review, we comprehensively dissect recent evidence regarding the interaction of the microbiome and anti-tumor immune machinery and outline the critical questions which need to be addressed as we further explore this dynamic colloquy.

RESUMEN

BACKGROUND: According to the American Association of Medical Colleges, women comprise 26% of full professors and 19% of medical school department chairs. African American and Latino faculty comprise 4.6% of full professors and 6.9% of department chairs. OBJECTIVE: Because of the lack of representation of women and racial/ethnic minority faculty at the highest levels of academic medicine, this study examines the perceptions of barriers to advancement by men and women academic medical school faculty of differing races and ethnicities to explore potential differences in perceptions by demographic group. DESIGN: Semi-structured one-on-one interviews were conducted between July and September 2017. PARTICIPANTS: In order to give all faculty a chance to participate, faculty of all ranks and specialties were recruited from one southeastern medical school to participate in the study. APPROACH: Interviews were audio recorded, transcribed, and analyzed by 3 members of the research team using an inductive approach to thematic analysis. Participants were organized into 4 groups for analysis-underrepresented in medicine (URiM) women, majority women, URiM men, majority men. KEY RESULTS: Sixty-four faculty consented to participate in the study (56.2% women, 34.4% URiM). Subthemes were grouped under three main themes: Perceptions of Barriers to Advancement of Women Faculty, Perceptions of Barriers to Advancement of African American and Latino Faculty, and Perceptions of the Institutional Climate for Diversity. Majority men tended to voice distinctly different perspectives than the other three demographic groups, with the most notable differences between majority men and URiM women. Majority  men tended to suggest that the advancement of women and URiM faculty was acceptable or getting better, the lack of URiM faculty in leadership was due mainly to pipeline issues, and women choose not to advance to leadership positions. CONCLUSION: We found that participant gender and race/ethnicity shaped perspectives of medical school faculty advancement in distinct ways.

RESUMEN

Bias based on skin color, religion, immigrant status, gender, and ethnicity are deeply rooted in American culture and have existed within the infrastructure of American medicine from the beginning. Now, medical educators are struggling to find curriculum and experiences that effectively address explicit and implicit bias among our increasingly diverse group of students, house staff, and practitioners. The leadership, experience, and lessons learned needed to scrub present medical school curricula of racial bias, to develop an antiracist curriculum, and to test its effectiveness already lies with the American Medical Association (AMA), the Association of American Medical Colleges (AAMC), and the National Medical Association (NMA). We call on these organizations to jointly convene a consortium of medical educators, social scientists, curricular specialists, and others to chart a way forward to assist medical schools and professional organizations in developing evaluable curricular materials and experiences to eliminate bias in health care.

RESUMEN

BACKGROUND: Pancreatic cancer is a leading cause of financial insolvency and cancer related deaths in the United States. The risk of catastrophic health expenditure (CHE) was calculated for patients undergoing pancreatic resection at an academic institution. METHODS: Patients who underwent pancreatic resection between 2013 and 2017 were identified through an institutional cancer registry. A CHE was an out-of-pocket payment (OOP) > 10% of the estimated median household income. RESULTS: 319 patients met inclusion criteria. Hospital median charge was $76,700. 99% of patients had insurance and hospital bill adjustments. As a result, 61% (n = 193) made no OOP. Only 3 patients risked CHE. For all tumors combined there were no differences in survival outcomes by OOP. CONCLUSION: This is the first study to use institutional financial data to calculate CHE risk for pancreatic resection patients. Insurance adjustments to hospital charges that accompany health insurance and voluntary hospital adjustments for the uninsured protect patients against CHE.
