Abstract Background Dimorphic fungal infections, such as blastomycosis, cause significant morbidity and mortality. Most studies describing blastomycosis have focused on non-Hispanic Caucasians and our understanding of the clinical presentation and outcomes for patients of other race/ethnicities is limited. We evaluated whether clinical presentation and disease severity varied across racial/ethnic groups. Methods Blastomycosis patients were identified from Marshfield Clinic Health System and patient data were abstracted from electronic medical records. Blastomyces genotyping was performed for cases with available isolates. Univariate analyses using χ 2 tests and multivariate logistic regression modeling were used to determine the association of race/ethnicity with clinical presentation. Significance was defined as P ≤ 0.05. Results In total 477 patients were included.Age differences were observed across race/ethnicity categories (P < 0.0001). Non-Hispanic, Caucasians were oldest (47 years, SD 20) and Asians were the youngest (30 years, SD 18). Underlying medical conditions were more common in non-Hispanic Caucasians (55%) and African Americans (AA) (52%) than Hispanic Caucasians (27%) and Asians (29%, P = 0.0002). Risk for hospitalization was highest for Hispanic Caucasian (aOR 2.9, 95% CI 1.2–1.7), American Indian Alaskan Native (AIAN) (aOR = 2.4; 95% CI 1.0–5.5), and Asian (aOR = 1.9; 95% CI 1.0–3.6) patients when compared with non-Hispanic Caucasian patients. Ninety percent of B. dermatitidis infections occurred in non-Hispanic Caucasians whereas blastomycosis in Hispanic Caucasian, AIAN, and Asian patients was frequently caused by B. gilchristii (P < 0.0001). Conclusion Hispanic Caucasian, AIAN, and Asian blastomycosis patients were younger and healthier, but more frequently hospitalized. Patients in these racial/ethnic groups may need more aggressive treatment and closer therapeutic monitoring. Underlying host factors along with organism virulence likely play a role in these differences. Disclosures All authors: No reported disclosures.

Abstract Background Dimorphic fungal infections, such as blastomycosis, cause significant morbidity and mortality. Historically, blastomycosis studies have focused on non-Hispanic whites, which limits our understanding of the clinical presentation and outcomes for patients of other races and ethnicities. We evaluated whether clinical presentation and disease severity varied across racial and ethnic groups. Methods Blastomycosis patients were identified from Marshfield Clinic Health System and data were abstracted from electronic medical records. Blastomyces genotyping was performed for cases with available isolates. Bivariate analyses (χ 2 tests/analysis of variance) assessed associations of race and/or ethnicity, Blastomyces spp, and hospitalization status with demographics and clinical presentation. Multivariable logistic regression was used to evaluate the association of race and/or ethnicity and hospitalization. Results In total, 477 patients were included. Age differences were observed across race and ethnicity categories (P < .0001). Non-Hispanic whites were oldest (median, 48 years; interquartile range [IQR], 31–62) and Asians were youngest (26 years; IQR, 19–41). Non-Hispanic whites (55%) and African Americans (52%) had underlying medical conditions more frequently than Hispanic whites (27%) and Asians (29%). Odds of hospitalization were 2 to 3 times higher for Hispanic whites (adjusted odds ratio [aOR], 2.9; 95% confidence interval [CI], 1.2–1.7), American Indian or Alaska Native (AIAN) (aOR, 2.4; 95% CI, 1.0–5.5), and Asian (aOR, 1.9; 95% CI, 1.0–3.6) patients compared with non-Hispanic white patients. Ninety percent of Blastomyces dermatitidis infections occurred in non-Hispanic whites, whereas blastomycosis in Hispanic whites, AIAN, and Asian patients was frequently caused by Blastomyces gilchristii (P < .0001). Conclusions Hispanic whites, AIAN, and Asian blastomycosis patients were younger and healthier but more frequently hospitalized. Patients in these racial and ethnic groups may need more aggressive treatment and closer therapeutic monitoring.

380 Background: Inequities in cancer survival are well documented. Whether disparities in overall survival (OS) result from inherent racial differences in underlying disease biology or socioeconomic factors (SEF) is not known. Our aim was to define the association of race/ethnicity and SEF with OS in pts with cholangiocarcinoma (CCA). Methods: Pts with CCA of all sites and stages in the National Cancer Data Base (2004-14) were included. Racial/ethnic groups were defined as non-Hispanic White (NH-W), non-Hispanic Black (NH-B), Asian, and Hispanic. Income and education were based on census data for pts’ zip code. Income was defined as high (³$63,000) vs low ( < $63,000). Primary outcome was OS. Results: 27,151 pts were included with a mean age of 68 yrs; 51% were male. 78% were NH-W, 8% NH-B, 6% Asian, and 6% Hispanic. 56% had Medicare, 33% private insurance, 7% Medicaid, and 4% were uninsured. 67% had high income. 21% lived in an area where > 20% of adults did not finish high school. NH-B and Hispanic pts had more unfavorable SEF including uninsured status, low income, and less formal education than NH-W and Asian pts (all p < 0.001). They were also younger, more likely to be female and to have metastatic disease (all p < 0.001). Despite this, NH-B race and Hispanic ethnicity were not associated with decreased OS. Male sex, older age, non-private insurance, low income, lower education, non-academic facility, location outside the Northeast, higher Charlson-Deyo score, worse grade, larger tumor size, and higher stage were all associated with decreased OS (all p < 0.001). On MV analysis, along with adverse pathologic factors, type of insurance (p = 0.003), low income (p < 0.001), and facility type and location of treatment (p < 0.001) remained associated with decreased OS; non-white race/ethnicity was not. Conclusions: Disparities in survival exist in CCA, however they are not driven by race/ethnicity. Non-privately insured and low-income pts had decreased OS, as did pts treated at non-academic centers and outside the Northeast. This suggests that decreased ability to access and afford care results in worse outcomes, rather than biological differences amongst racial/ethnic groups.

6570 Background: Patients with multiple myeloma (MM) who are part of racial/ethnic minority groups have been typically underrepresented in large descriptive and randomized-controlled studies. Despite the identification of biological and genetic risk factors, the impact of race/ethnicity in the outcomes of patients with MM remains largely unknown. We aimed to describe the racial/ethnic differences in clinical presentation and outcomes of patients with MM in an ethnically-diverse underserved urban population. Methods: We conducted a single-center retrospective study of patients with MM from Jan 1st 2008 – Dec 31st 2016 using ICD coding from our tumor registry. We abstracted demographic, clinical and treatment variables. We used Chi-square to compare categorical variables and Kaplan-Meier method for survival analysis. Statistical analysis was performed using IBM SPSS version 25. Results: We identified 73 patients with MM with a median follow up time of 42 months (Range 1 to 81 months). Patients had a median age of 59 years (Interquartile Range [IQR] =17) and were predominantly male (54.8%). The most frequent racial/ethnic group was African American (AA) (59%) followed by Hispanic (27%) and Caucasian (8%). When compared to other ethnicities, patients who were AA had higher ISS-3 scores (41% vs 23% p=0.101) worse cytogenetic risk (65% vs 30% p=0.009) and worse response after induction (Complete response [CR] 47% vs 77% p=0.047). They were also more likely to have medical insurance coverage than other ethnicities (67% vs 27% p=0.003) but had similar access to autologous bone marrow transplant (23% vs 23% p= 0.99). Overall, AA patients had worse overall survival (OS) compared to all other ethnic groups (mean OS: 58.3 months vs 79 months p=0.014). Conclusions: AA patients with MM had more aggressive disease and worse OS compared to other ethnicities which may suggest an underlying genetic predisposition towards high-risk genetic features. Improvement of access to autologous bone marrow transplantation may improve survival in high-risk racial/ethnic groups.

Abstract Background Racial/ethnic disparities in HIV outcomes have persisted despite effective antiretroviral therapy. In a study of initial regimens, we found viral suppression varied by race/ethnicity. In this exploratory analysis, we use clinical and socioeconomic data to assess factors associated with virologic failure and adverse events within racial/ethnic groups. Methods Data were from AIDS Clinical Trial Group A5257, a randomized trial of initial regimens with either atazanavir/ritonavir, darunavir/ritonavir, or raltegravir (each combined with tenofovir DF and emtricitabine). We grouped participants by race/ethnicity and then used Cox-proportional hazards regression to examine the impact of demographic, clinical, and socioeconomic factors on the time to virologic suppression and time to adverse event reporting within each racial/ethnic group. Results We analyzed data from 1762 participants: 757 self-reported as non-Hispanic black (NHB), 615 as non-Hispanic white (NHW), and 390 as Hispanic. The proportion with virologic failure was higher for NHB (22%) and Hispanic (17%) participants compared with NHWs (9%). Factors associated with virologic failure were poor adherence and higher baseline HIV RNA level. Prior clinical AIDS diagnosis was associated with virologic failure for NHBs only, and unstable housing and illicit drug use for NHWs only. Factors associated with adverse events were female sex in all groups and concurrent use of medications for comorbidities in NHB and Hispanic participants only. Conclusions Clinical and socioeconomic factors that are associated with virologic failure and tolerability of antiretroviral therapy vary between and within racial and ethnic groups. Further research may shed light into mechanisms leading to disparities and targeted strategies to eliminate those disparities.

BACKGROUND The prevalence of depression symptoms in the United States is >3 times higher mid–COVID-19 versus pre-pandemic. Racial/ethnic differences in mindsets around depression and the potential impact of the COVID-19 pandemic are not well characterized. OBJECTIVE To describe attitudes, mindsets, key drivers, and barriers related to depression pre– and mid–COVID-19 by race/ethnicity using digital conversations about depression mapped to health belief model (HBM) concepts. METHODS Advanced search, data extraction, and AI-powered tools were used to harvest, mine, and structure open-source digital conversations of US adults who engaged in conversations about depression pre– (February 1, 2019-February 29, 2020) and mid–COVID-19 pandemic (March 1, 2020-November 1, 2020) across the internet. Natural language processing, text analytics, and social data mining were used to categorize conversations that included a self-identifier into racial/ethnic groups. Conversations were mapped to HBM concepts (ie, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy). Results are descriptive in nature. RESULTS Of 2.9 and 1.3 million relevant digital conversations pre– and mid–COVID-19, race/ethnicity was determined among 1.8 million (62%) and 979,000 (75%) conversations pre– and mid–COVID-19, respectively. Pre–COVID-19, 1.3 million conversations about depression occurred among non-Hispanic Whites (NHW), 227,200 among Black Americans (BA), 189,200 among Hispanics, and 86,800 among Asian Americans (AS). Mid–COVID-19, 736,100 conversations about depression occurred among NHW, 131,800 among BA, 78,300 among Hispanics, and 32,800 among AS. Conversations among all racial/ethnic groups had a negative tone, which increased pre– to mid–COVID-19; finding support from others was seen as a benefit among most groups. Hispanics had the highest rate of any racial/ethnic group of conversations showing an avoidant mindset toward their depression. Conversations related to external barriers to seeking treatment (eg, stigma, lack of support, and lack of resources) were generally more prevalent among Hispanics, BA, and AS than among NHW. Being able to benefit others and building a support system were key drivers to seeking help or treatment for all racial/ethnic groups. CONCLUSIONS Applying concepts of the HBM to data on digital conversation about depression allowed organization of the most frequent themes by race/ethnicity. Individuals of all groups came online to discuss their depression. There were considerable racial/ethnic differences in drivers and barriers to seeking help and treatment for depression pre– and mid–COVID-19. Generally, COVID-19 has made conversations about depression more negative, and with frequent discussions of barriers to seeking care. These data highlight opportunities for culturally competent and targeted approaches to address areas amenable to change that might impact the ability of people to ask for or receive mental health help, such as the constructs that comprise the HBM.

Introduction Risk factors for cancer-associated venous thromboembolism (CAT) include tumor type, stage at diagnosis, age, and patient comorbidities. In the general population, race/ethnicity has been identified as a risk factor for venous thromboembolism (VTE), with an increased risk of VTE in African Americans (AA) and a lower risk in Asians/Pacific Islanders (API) and Hispanics compared to non-Hispanic Whites (NHW) after adjustment for confounders such as demographic characteristics and patient comorbidities. However, the impact of race/ethnicity on the incidence of CAT has not been as well-studied. Methods We performed an observational cohort study using data from the California Cancer Registry linked to the California Patient Discharge Dataset and Emergency Department Utilization database. We identified a cohort of patients of all ages with first primary diagnosis of the 13 most common cancers in California between 2005-2014, including breast, prostate, lung, colorectal, bladder, uterine, kidney, pancreatic, stomach, ovarian, and brain cancer, Non-Hodgkin lymphoma, and multiple myeloma, and followed them for a diagnosis of VTE using specific ICD-9-CM codes. The 12-month cumulative incidences of VTE [pulmonary embolism (PE) alone, PE + lower extremity deep venous thrombosis (LE DVT), proximal LE DVT alone, and isolated distal DVT (iDDVT)] were determined by race/ethnicity, adjusted for the competing risk of death. Multivariable Cox proportional hazards regression models were performed to determine the effect of race/ethnicity on the risk of CAT adjusted for age, sex, cancer stage, type of initial therapy (surgery, chemotherapy, radiation therapy), neighborhood socioeconomic status, insurance type, and comorbidities. Patients with VTE prior to cancer diagnosis were excluded. Results A total of 736,292 cancer patients were included in the analysis cohort, of which 38,431 (5.2%) developed CAT within 12 months of diagnosis. When comparing the overall cancer cohort to those that developed VTE, AA (7.2 vs 10.5%) and NHW (61.9 vs 64.3%) appear to be over-represented, and API (11.6 vs 7.6%) under-represented in VTE cohort (Figure 1). The greatest disparities in incidence by race/ethnicity were seen in PE. AA had the highest and API had the lowest 12-month cumulative incidences for all cancer types except for brain cancer (Figure 2). These racial/ethnic differences were also seen among cumulative incidences of proximal LE DVT. For iDDVT, AA again had the highest cumulative incidence compared to the other racial groups among all cancer types except for myeloma. Racial differences were not as prominent when examining cumulative incidence of all VTE (PE+DVT). In adjusted multivariable models of overall CAT, compared to NHW, AA had the highest risk of CAT across all cancer types except for brain cancer and myeloma. API had significantly lower risk of CAT than NHW for all cancer types. When examining PE only in multivariable models, AA had significantly higher risk of PE compared to NHW in all cancer types except for kidney, stomach, brain cancer, and myeloma (Hazard Ratio (HR) ranging from 1.36 to 2.09). API had significantly lower risk of PE in all cancer types except uterine, kidney, and ovarian cancer (HR ranging from 0.45 to 0.87). Hispanics had lower risk of PE than NHW in breast, prostate, colorectal, bladder, pancreatic cancer, and myeloma (HR ranging from 0.64 to 0.87). [Figure 3] Conclusion In this large, diverse, population-based cohort of cancer patients, race/ethnicity was associated with risk of CAT even after adjusting for cancer stage, type of treatment, sociodemographic factors, and comorbidities. Overall, AA had a significantly higher incidence and API had a significantly lower incidence of CAT than NHW. These racial/ethnic differences were especially prominent when examining PE only, and PE appears to be the main driver for the racial differences observed in overall rates of CAT. Current risk prediction models for CAT do not include race/ethnicity as a parameter. Future studies might examine if incorporation of race/ethnicity into risk prediction models for CAT may improve their predictive value, as this may have important implications for thromboprophylaxis in this high-risk population.

Accumulating evidence suggests that reproductive potential and function may be different across racial and ethnic groups. Racial differences have been demonstrated in pubertal timing, infertility, outcomes after assisted reproductive technology (ART) treatment, and reproductive aging. Recently, racial differences have also been described in serum antimüllerian hormone (AMH), a sensitive biomarker of ovarian reserve, supporting the notion that ovarian reserve differs between racial/ethnic groups. The existence of such racial/ethnic differences in ovarian reserve, as reflected by AMH, may have important clinical implications for reproductive endocrinologists. However, the mechanisms which may underlie such racial differences in ovarian reserve are unclear. Various genetic factors and environmental factors such as obesity, smoking, and vitamin D deficiency which have been shown to correlate with serum AMH levels and also display significant racial/ethnic variations are discussed in this review. Improving our understanding of racial differences in ovarian reserve and their underlying causes may be essential for infertility treatment in minority women and lead to better reproductive planning, improved treatment outcomes, and timely interventions which may prolong reproductive lifespan in these women.

Abstract Little information exists on the associations between intellectual disability (ID) and race/ethnicity on mammogram frequency. This study collected survey and medical record data to examine this relationship. Results indicated that Hispanic and Black women with ID were more likely than White women with ID to have mammograms every 2 years. Participants who live in a state-funded residence, were aged 50+, and had a mild or moderate level of ID impairment were more likely to undergo mammography compared to participants living with family or alone, were &lt;50, and had severe ID impairment. Further research is needed to understand the mechanisms explaining disparities in mammograms between these racial/ethnic groups.

ObjectiveTo estimate the risk of intracerebral hemorrhage (ICH) recurrence in a large, diverse, US-based population and to identify racial/ethnic and socioeconomic subgroups at higher risk.MethodsWe performed a longitudinal analysis of prospectively collected claims data from all hospitalizations in nonfederal California hospitals between 2005 and 2011. We used validated diagnosis codes to identify nontraumatic ICH and our primary outcome of recurrent ICH. California residents who survived to discharge were included. We used log-rank tests for unadjusted analyses of survival across racial/ethnic groups and multivariable Cox proportional hazards regression to determine factors associated with risk of recurrence after adjusting for potential confounders.ResultsWe identified 31,355 California residents with first-recorded ICH who survived to discharge, of whom 15,548 (50%) were white, 6,174 (20%) were Hispanic, 4,205 (14%) were Asian, and 2,772 (9%) were black. There were 1,330 recurrences (4.1%) over a median follow-up of 2.9 years (interquartile range 3.8). The 1-year recurrence rate was 3.0% (95% confidence interval [CI] 2.8%–3.2%). In multivariable analysis, black participants (hazard ratio [HR] 1.22; 95% CI 1.01–1.48; p = 0.04) and Asian participants (HR 1.29; 95% CI 1.10–1.50; p = 0.001) had a higher risk of recurrence than white participants. Private insurance was associated with a significant reduction in risk compared to patients with Medicare (HR 0.60; 95% CI 0.50–0.73; p < 0.001), with consistent estimates across racial/ethnic groups.ConclusionsBlack and Asian patients had a higher risk of ICH recurrence than white patients, whereas private insurance was associated with reduced risk compared to those with Medicare. Further research is needed to determine the drivers of these disparities.

Abstract Objectives This study assessed historical and current gender, racial, and ethnic diversity trends within US pathology graduate medical education (GME) and the pathologist workforce. Methods Data from online, publicly available sources were assessed for significant differences in racial, ethnic, and sex distribution in pathology trainees, as well as pathologists in practice or on faculty, separately compared with the US population and then each other using binomial tests. Results Since 1995, female pathology resident representation has been increasing at a rate of 0.45% per year (95% confidence interval [CI], 0.29-0.61; P &lt; .01), with pathology now having significantly more females (49.8%) compared to the total GME pool (45.4%; P &lt; .0001). In contrast, there was no significant trend in the rate of change per year in black or American Indian, Alaskan Native, Native Hawaiian, and Pacific Islander (AI/AN/NH/PI) resident representation (P = .04 and .02). Since 1995, underrepresented minority (URM) faculty representation has increased by 0.03% per year (95% CI, 0.024-0.036; P &lt; .01), with 7.6% URM faculty in 2018 (5.2% Hispanic, 2.2% black, 0.2% AI/AN/NH/PI). Conclusions This assessment of pathology trainee and physician workforce diversity highlights significant improvements in achieving trainee gender parity. However, there are persistent disparities in URM representation, with significant underrepresentation of URM pathologists compared with residents.
