Abstract 4148077: Heart Failure Mortality Between 1990 and 2020 by US State and Racial and Ethnic Group

Introduction: Heart failure (HF) mortality rates in the US appear to have increased in the past decade. It is unknown how these have changed in recent years by racial and ethnic groups within states. Research Question: To understand disparities in HF mortality patterns between 1990 and 2020 Aim: To estimate the change in HF mortality rates between 1990 and 2020 for Hispanic, non-Hispanic Black, and non-Hispanic White males and females in each US state Methods: We used multiple cause of death records from the National Vital Statistics System and population data from the National Center for Health Statistics to estimate HF mortality from 1990 to 2020 by state, age group, sex, and racial and ethnic group. A binomial model was fit to the data using RegMod, a Bayesian extension of a generalized linear model which incorporated priors from a hierarchy and modeled year as a spline. Results: In 2020, we estimated 566230 (95% UI 566160 to 569740) deaths due to HF. Between 1990 and 2010, HF rates declined in general for all racial and ethnic groups across the US, but not consistently for all states (Figure). From 2010 to 2020, this trend reversed, with age-standardized mortality from HF increasing over this time period, but again this change was not consistent across states. Among the Hispanic population, mortality increased for all states except for Maine, with the largest change for both sexes in Oklahoma. For the non-Hispanic, Black group, mortality increased among all states, with the largest change for both sexes in Oklahoma and South Dakota. Among the non-Hispanic, White populations, mortality decreased for both sexes in District of Columbia, while the largest increases were in Oklahoma. Conclusion: Heart failure mortality increased in the past decade, with striking increases in specific locations by race and ethnic group. Identifying etiologies and drivers of increased HF deaths, including the role of new therapies for subsets of systolic function, could help target novel therapies to subpopulations at highest risk. Differences in trends by state and race and ethnicity groups provides important information for clinicians and policymakers interested in reducing mortality rates.

Sex-specific association between platelet content and bone mineral density in adults: a cross-sectional study

BackgroundOsteoporosis (OP) is a complex skeletal disorder characterized by reduced bone mass, microarchitectural deterioration of bone tissue, and increased susceptibility to fractures. Bone mineral density (BMD), as the best indicator of bone mineral content per unit area of bone, is one of the key diagnostic factors for OP. Platelets (PLT), serving as important immune cells and components of the coagulation system, have been demonstrated to be associated with bone formation, resorption, and remodeling processes. However, no research has established the relationship between BMD and platelet count (PC) in the American population thus far. This study aims to investigate the correlation between BMD and PC among the American population, and to appraise the effects of additional risk factors on this association.MethodsThis investigation examined the relationship between BMD and PC by analyzing data from the National Health and Nutrition Examination Survey (NHANES) between 2011 and 2018. A weighted multivariate logistic regression analysis was employed to assess this correlation. Additionally, subgroup and smooth curve analyses were conducted to delve deeper into the BMD-PC relationship and to identify other potential determinants of PC.ResultsThis study reveals a significant negative correlation between BMD and PC in the American adult population (β=-15.05, 95% CI: -22.07 to -8.03, p < 0.0001). Subgroup analysis highlights notable differences in this correlation between genders and various racial groups. Smooth curve fitting and generalized additive models were applied to further explore the relationship between BMD and PC, considering the influence of multiple factors.ConclusionThe present study investigated the correlation between BMD and PC in adults, with a particular focus on the potential risk factors for thrombocytopenia. This negative correlation was found to be markedly pronounced in males, an association not observed in females. Additionally, a potential inverse relationship between BMD and hemoglobin (HGB) levels was identified. Consequently, for individuals with elevated bone mass or osteoporosis (OP), we advocate for routine complete blood count monitoring to identify hematological irregularities. Considering the significant variations by sex, age, and race, special vigilance is advised for changes in PC among non-Hispanic white males under the age of 55.

Racial and Ethnic Disparities in Dietary Intake and Quality Among United States Veterans

BackgroundDietary quality plays an important role in disease development and prognosis, and diet is also a key contributor to disparities in many chronic diseases and health conditions. ObjectivesThis study aimed to assess racial and ethnic disparities experienced by veterans; we examined food intake and dietary quality across different racial and ethnic groups of United States veterans. MethodsThe study included 420,730 males and females aged 19–107 y (91.2% males) enrolled in the Veterans Affairs Million Veteran Program with plausible dietary intake measured by food frequency questionnaire. Dietary quality was evaluated with dietary approaches to stop hypertension (DASH) score. Dietary intakes of various race and ethnicity groups were standardized to the age distribution of non-Hispanic White participants, separately for males and females. Differences across race and ethnicity groups were compared using general linear regression models after adjustment for socioeconomic and lifestyle factors as well as military service. ResultsCompared to non-Hispanic White males, non-Hispanic Black males had a relatively lower DASH score, higher red and processed meats, higher sugar-sweetened beverages (SSBs), and lower low-fat dairy intakes. Non-Hispanic Asian males had a relatively higher DASH score as compared to non-Hispanic White males with relatively higher intakes of fruits and vegetables and relatively lower intakes of sodium, red meat and SSBs. Age-standardized DASH scores of Hispanic males and “Other” race/ethnicity groups were not statistically different from non-Hispanic White males. Similar race and ethnicity dietary patterns were found in females, although not all reached a statistically significant level. ConclusionsA modest difference in overall dietary quality (i.e., DASH score) was observed, but unique differences in food preferences across the different racial/ethnic groups were identified. Findings from our study may provide insight for the potential development of specific interventions to help address nutritional disparities experienced among veterans.

Exploring adolescent suicidal trajectories: The intersection of race/ethnicity, gender, and social connectedness.

Understanding adolescent racial/ethnic and gender disparities in suicidal ideation and attempts longitudinally can help curb future suicidal risk. Survey data (1994-2008) from the Longitudinal Study of Adolescent to Adult Health (Add Health study, n = 18,887) examined racial/ethnic and gender ideation and attempt disparities over four waves of data from across the United States (51% female; 51% White; Mage = 17.43 years at Wave 1). Repeated-measures latent class analyses described how ideation and attempt patterns present longitudinally and how racial/ethnic minority groups predict different classes based on each wave and age-appropriate social supports (i.e., parents, peers). Those most at-risk disclosed ideation and some attempt risk in early adolescence (Waves 1 and 2) and mostly identified as female. The second most prevalent group first disclosed ideation in their 20s and predominately identified as non-Hispanic White females. Peer connections were not significant for most groups except for non-Hispanic White males in Wave 3, while Black females who reported stronger school connections had decreased ideation and attempt rates in Wave 1 but not 2 (just 1 year later). A negative link between social supports and high-risk ideation and attempt classes was found among Black females, non-Hispanic Whites, and Latinos overall. As the United States becomes more diverse, understanding the unique ideation and attempt disparities are crucial. Tailoring interventions to include risk and protective mechanisms among intersectional communities could eradicate disparities. Longitudinal studies can illuminate how protective and risk factors can change over time and even within and among racial/ethnic and gender groups.

Race differences in the impact of juvenile detention on likelihood of young adult incarceration of males aging out of care

Youth involved in the child welfare system are more likely to be involved in the juvenile justice system, and juvenile justice involvement is linked to increased likelihood of subsequent incarceration. For these reasons, overrepresentation of Black youth in the child welfare system contributes to racial disparities in incarceration rates. It is, therefore, important to study youth transitioning out of foster care to examine how their young adult outcomes differ by race. Employing the National Youth in Transition Database (NYTD), this study compared the incarceration experiences of non-Hispanic White and Black males aging out of foster care. Specifically, this study examined the impact of juvenile detention on the likelihood of incarceration ages 19 to 21and factors that mediated this relationship. Notably, 33.5% of White males and 30.7% of Black males in the sample experienced juvenile detention. Findings indicate that juvenile detention disproportionately impacts Black males who age out of foster care compared to their White counterparts. The direct effect of juvenile detention on reported incarceration between age 19–21 for Black males in the sample was OR = 2.31 compared to OR = 1.91 for White males. Reported incarceration between age 17–19 significantly mediated the relationship between juvenile confinement and incarceration age 19–21 for both Black and White males in the sample, although this effect was substantially stronger for Black males. Research and policy implications are discussed.

Measurements of Abdominal Obesity are Associated with Metabolic Syndrome Severity Independent of Hypertensive Phenotype in White but not Black Young Adults.

This study sought to determine if metabolic syndrome severity (MetSindex) was differentially associated with abdominal obesity based on waist circumference (WC) site and the presentation of hypertensive phenotypes in a group of young White and Black adults. A total of 139 young adult (22.5 ± 3.3 years) non-Hispanic White (n = 73) and non-Hispanic Black (n = 66) males and females (M 53, 86 F) completed this cross-sectional evaluation. Participants had their WC measured at three distinct locations along the abdomen which were used to calculate waist-to-hip and waist-to-height ratios. Systolic (SBP) and diastolic blood pressure (DBP) were collected and used to calculate mean arterial pressure (MAP). In addition to traditional metabolic syndrome (MetS) risk factors, BP values were individually used to produce three separate MetSindex scores representing three specific hypertensive phenotypes (MetSSBP, MetSDBP, MetSMAP), and each of these were evaluated against each abdominal obesity estimate. MetSDBP and MetSSBP were significantly higher than all other indices for females (all p ≤ 0.002) and males (all p < 0.001), respectively. MetSDBP was significantly higher than MetSMAP for White females (p = 0.039), and MetSSBP was significantly higher than MetSDBP and MetSMAP (both p < 0.001) for Black males. Standalone and joint estimates of abdominal obesity were uniquely associated with MetSindex across hypertensive phenotypes for White, but not Black males and females. Specific hypertensive phenotypes may differentially determine MetSindex, but these estimates are not associated with abdominal obesity in young Black adults regardless of measurement location. Healthcare professionals should address this disparity by providing more comprehensive MetS screening procedures for young Black adults. NCT05885672.

Do Substances Used in Adolescence Predict the Persistence of Substance Use Disorders in Adulthood? A 15-Year Study of Youth After Detention

PurposeInvestigate if the type of substance use disorder (SUD) in adolescence predicts SUDs in adulthood and examine sex and racial/ethnic differences in the persistence of SUDs. MethodsData are from the Northwestern Juvenile Project, a 15-year longitudinal study of 1829 youth randomly sampled from detention in Chicago, IL (1995–1998). Interviewers assessed SUDs using structured diagnostic interviews. ResultsCompared with females without an SUD at detention, females with cannabis alone, comorbid alcohol and cannabis, or SUDs other than alcohol and cannabis at detention had higher odds of having an SUD 5 years later (25%, 32%, and 36% vs. 15%, adjusted odds ratio [AOR] = 1.94, 95% confidence interval [CI] 1.11–3.40; AOR = 2.76, 95% CI 1.58–4.83; AOR = 3.46, 95% CI 1.56–7.66, respectively). Males and females with SUDs other than alcohol and cannabis at detention had greater odds of having an SUD 15 years later, compared with those without an SUD at detention (males: 36% vs. 14%, AOR = 2.98, 95% CI 1.14–7.83; females: 29% vs. 8%, AOR = 4.77, 95% CI 1.85–12.30). Among youth with an SUD at detention, males were more likely than females to have an SUD 15 years later (AOR = 1.84, 95% CI 1.03–3.29); non-Hispanic White and Hispanic males were more likely to persist than Black males (AOR = 3.32, 95% CI 1.50–7.35; AOR = 2.32, 95% CI 1.04–5.18, respectively). DiscussionThe type of SUD during adolescence matters. Youth with SUDs such as cocaine and opioids fared the worst. Healthcare providers must collaborate with correctional officials to increase service provision.

Racial Differences in Germline Genetic Testing Completion Among Males With Pancreatic, Breast, or Metastatic Prostate Cancers.

Germline genetic testing is a vital component of guideline-recommended cancer care for males with pancreatic, breast, or metastatic prostate cancers. We sought to determine whether there were racial disparities in germline genetic testing completion in this population. This retrospective cohort study included non-Hispanic White and Black males with incident pancreatic, breast, or metastatic prostate cancers between January 1, 2019, and September 30, 2021. Two nationwide cohorts were examined: (1) commercially insured individuals in an administrative claims database, and (2) Veterans receiving care in the Veterans Health Administration. One-year germline genetic testing rates were estimated by using Kaplan-Meier methods. Cox proportional hazards regression was used to test the association between race and genetic testing completion. Causal mediation analyses were performed to investigate whether socioeconomic variables contributed to associations between race and germline testing. Our cohort consisted of 7,894 males (5,142 commercially insured; 2,752 Veterans). One-year testing rates were 18.0% (95% CI, 16.8%-19.2%) in commercially insured individuals and 14.2% (95% CI, 11.5%-15.0%) in Veterans. Black race was associated with a lower hazard of testing among commercially insured individuals (adjusted hazard ratio [aHR], 0.73; 95% CI, 0.58-0.91; P=.005) but not among Veterans (aHR, 0.99; 95% CI, 0.75-1.32; P=.960). In commercially insured individuals, income (aHR, 0.90; 95% CI, 0.86-0.96) and net worth (aHR, 0.92; 95% CI, 0.86-0.98) mediated racial disparities, whereas education (aHR, 0.98; 95% CI, 0.94-1.01) did not. Overall rates of guideline-recommended genetic testing are low in males with pancreatic, breast, or metastatic prostate cancers. Racial disparities in genetic testing among males exist in a commercially insured population, mediated by net worth and household income; these disparities are not seen in the equal-access Veterans Health Administration. Alleviating financial and access barriers may mitigate racial disparities in genetic testing.

Abstract 3943: Refined race and ethnicity categories for an EHR-based cohort to study disparities in liver cancer risk

Abstract Purpose: To develop a schema for harmonized, detailed characterization of race and ethnicity data for an electronic health record (EHR)-based cohort linked to cancer registry data to assess disparities in hepatocellular carcinoma (HCC) risk. Methods: We assembled an cohort of adults with 1+ encounter in 2000-2017 by pooling EHR data from three healthcare systems (Kaiser Permanente Hawai’i, Sutter Health, San Francisco Health Network). EHR data to define sociodemographic and clinical factors were linked to population-based state cancer registries for data on incident HCC (ICD-03 site/histology C22.0/8170-8175) through 2017. We extracted, harmonized and developed schemas to characterize multiple response race and ethnicity data across systems. We used Cox proportional hazards regression to examine disparities in HCC risk across racial and ethnic groups, comparing observations across categorization schema. Results: The cohort included 4,248,553 adults; 2,916 had incident HCC. A race and ethnicity schema that prioritized small populations and disaggregation of heterogenous groups defined 16 categories and was used to analyze pooled data from Kaiser Permanente Hawai’i and Sutter Health. With this schema, we observed variation in HCC risk across ethnic groups that are typically aggregated into larger ethno-racial categories (e.g., Asian American). Compared to non-Hispanic (NH) White males, Vietnamese American males had greater risk of HCC (hazard ratio (HR): 7.42; 95% CI: 4.25, 12.96) as did American Indian/Alaska Native, Black, Chinese American, Hispanic, Native Hawaiian, and Pacific Islander males; Asian Indian, Filipino, Japanese, and Korean American males did not. Among females, every group except American Indian/Alaska Native, Asian Indian American, and Pacific Islander females had greater risk of HCC than the NH White group. Due to less granular data from San Francisco Health Network during our study period, we developed a second, grouped schema aggregating categories from the detailed schema; it resulted in seven race and ethnicity categories and was used to analyze pooled data from all three healthcare systems. Compared to the categorization of race and ethnicity used by the US Census, which also has seven categories, we observed different patterns in HCC risk disparities for the smallest groups (i.e., American Indian/Alaska Native and Native Hawaiian). Conclusions: Analysis of a large EHR-based cohort linked to cancer registry data using a race and ethnicity characterization schema that prioritizes small populations yields valuable knowledge on disparities in HCC risk. Thus, to advance research on health disparities using EHR data, researchers must critically assess racial and ethnic categories typically available from healthcare system data repositories. We offer recommendations to operationalize EHR data on race and ethnicity to facilitate its meaningful use in research. Citation Format: Mindy C. DeRouen, Caroline A. Thompson, Alison J.

Abstract 4805: Identifying neighborhood hot spots of HPV-associated cancers for targeted interventions of HPV vaccination uptake in underserved communities of South Florida

Abstract Background: Although the incidence of cervical cancer in the US has declined, the incidences of other HPV-associated cancers are on the rise. HPV vaccination is an important primary prevention strategy for reducing the burden of HPV-associated cancers. In South Florida (population over 6 million), the percentage of adolescents aged 13-15 years who completed the recommended HPV vaccine series is 54%, which lags significantly behind the Healthy People 2030 target of 80%. In addition, vaccination disparities exist in South Florida by races/ethnicities and sexes, with non-Hispanic black males having the lowest rate at 27%. To address HPV cancer disparities, we performed a geospatial analysis on the incidence of HPV-associated cancers by sex and races/ethnicity to identify communities in South Florida with high incidence of HPV-associated cancer to target interventions that may improve HPV-vaccine uptake via community outreach and engagement. Methods: The average annual (2010-2019) incidence of HPV-associated cancers in women (cervical, oropharyngeal, vulva, vaginal, and anal) and men (oropharyngeal, penile, and anal) were calculated for Hispanics, Non-Hispanic Whites (NHWs) and Non-Hispanic Blacks (NHB) at the census tract level across South Florida using data from the Florida Cancer Data System (FCDS), the state incident cancer registry. Geospatial hot spot analyses were used to identify clusters of census tracts with high HPV cancer incidence by sex and race/ethnicity. Socioeconomic and cervical screening data of the hot spots were analyzed to identify other neighborhood risk conditions that may be associated with high HPV cancer risk. Results: For Hispanics and NHBs in South Florida, census tract hot spots for male and female HPV cancers appear to overlap in low-income neighborhoods; however, hot spots for NHW males are mostly in medium to higher income areas and do not overlap with hot spots observed for NHW females, likely given that NHW females generally report higher cervical screening rates. Conclusion: There is a positive association between male and female HPV cancer incidence in Hispanic and NHB communities of South Florida, justifying the need for increased HPV vaccination and screening programs in these neighborhoods. While increasing cervical screening rate in the hot spot neighborhoods is urgent for cervical cancer control, increasing gender-neutral HPV vaccination uptake in these communities will not only reduce the incidences of male HPV cancers but also help to accelerate cervical cancer elimination by reducing HPV infection.

The impact of metabolic syndrome severity on racial and ethnic disparities in Metabolic Dysfunction-Associated Steatotic Liver Disease.

Previous studies have examined the effects of metabolic syndrome (MetS) rather than its severity on race and ethnic disparities in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD). We used the MetS severity score, a validated sex-race-ethnicity-specific severity measure, to examine the effects of race/ethnicity on the association between MetS severity and MASLD. This study included 10,605 adult participants from the Third National Health and Nutrition Examination Survey. The MASLD diagnosis was based on ultrasound findings in patients without excessive alcohol intake or other liver diseases. MetS severity Z-scores were calculated and stratified into four categories low (1st-50th), moderate (>50th-75th), high (>75th-90th), and very high (>90th+)]. Multivariable adjusted logistic regression models with complex survey methods were used to test the effect of MetS severity on MASLD. The age-adjusted MASLD prevalence was 17.4%, 25.7%, 42.5, and 54.9% in adults with mild, moderate, high, and very high MetS severities, respectively (P-trend <0.001). MetS severity was significantly higher in patients with MASLD than in those without [mean percentile 60th vs. 44th, P<0.001]. Among patients with MASLD, Mexican-American and Black non-Hispanic females had significantly higher age-adjusted MetS severity (68th and 61st, respectively) than White non-Hispanic females 54th, while Black non-Hispanic males had significantly lower MetS severity (56th) than White non-Hispanic males (70th) (P-Interaction = 0.02). Adults with high and very high MetS severity had 2.27 (95% CI:1.70 to 3.03) and 3.12 (95% CI:2.20 to 4.42), respectively, higher adjusted odds of MASLD than those with mild MetS severity. Racial/ethnic disparities in MetS severity play a pivotal role in the risk of MASLD. Our findings highlight the potential clinical utility of the MetS severity score in identifying at-risk individuals, which will help guide targeted prevention and tailoring management strategies to mitigate the MASLD burden.

Surgeon Intersectionality and Academic Promotion and Retention in the US

Efforts have been made to increase the number of women and physicians who are underrepresented in medicine (UIM). However, surgery has been slow to diversify, and there are limited data surrounding the impact of intersectionality. To assess the combined association of race and ethnicity and sex with rates of promotion and attrition among US academic medical department of surgery faculty. This was a retrospective cohort study using faculty roster data from the Association of American Medical Colleges. All full-time academic department of surgery faculty with an appointment any time from January 1, 2005, to December 31, 2020, were included. Study data were analyzed from September 2022 to February 2023. Full-time academic faculty in a department of surgery with a documented self-reported race, ethnicity, and sex within the designated categories of the faculty roster of Association of American Medical Colleges. Trends in race and ethnicity and sex, rates of promotion, and rates attrition from 2010 to 2020 were assessed with Kaplan-Meier and Cox time-to-event analyses. A total of 31 045 faculty members (23 092 male [74%]; 7953 female [26%]) from 138 institutions were included. The mean (SD) program percentage of UIM male faculty increased from 8.4% (5.5%) in 2010 to 8.5% (6.2%) in 2020 (P < .001), whereas UIM female faculty members increased from 2.3% (2.6%) to 3.3% (2.5%) over the 10-year period (P < .001). The mean program percentage of non-UIM females increased at every rank (percentage point increase per year from 2010 to 2020 in instructor: 1.1; 95% CI, 0.73-1.5; assistant professor: 1.1; 95% CI, 0.93-1.3; associate professor: 0.55; 95% CI, 0.49-0.61; professor: 0.50; 95% CI, 0.41-0.60; all P < .001). There was no change in the mean program percentage of UIM female instructors or full professors. The mean (SD) percentage of UIM female assistant and associate professors increased from 3.0% (4.1%) to 5.0% (4.0%) and 1.6% (3.2%) to 2.2% (3.4%), respectively (P =.002). There was no change in the mean program percentage of UIM male instructors, associate, or full professors. Compared with non-Hispanic White males, Hispanic females were 32% less likely to be promoted within 10 years (hazard ratio [HR], 0.68; 95% CI, 0.54-0.86; P <.001), non-Hispanic White females were 25% less likely (HR, 0.75; 95% CI, 0.71-0.78; P <.001), Hispanic males were 15% less likely (HR, 0.85; 95% CI, 0.76-0.96; P =.007), and Asian females were 12% less likely (HR, 0.88; 95% CI, 0.80-0.96; P =.03). Non-UIM males had the shortest median (IQR) time to promotion, whereas non-UIM females had the longest (6.9 [6.8-7.0] years vs 7.2 [7.0-7.6] years, respectively; P < .001). After 10 years, 79% of non-UIM males (13 202 of 16 299), 71% of non-UIM females (3784 of 5330), 68% of UIM males (1738 of 2538), and 63% of UIM females (625 of 999) remained on the faculty. UIM females had a higher risk of attrition compared with non-UIM females (HR, 1.3; 95% CI, 1.1-1.5; P = .001) and UIM males (HR, 1.2; 95% CI, 1.0-1.4; P = .05). The mean (SE) time to attrition was shortest for UIM females and longest for non-UIM males (8.2 [0.14] years vs 9.0 [0.02] years, respectively; P < .001). Results of this cohort study suggest that intersectionality was associated with promotion and attrition, with UIM females least likely to be promoted and at highest risk for attrition. Further efforts to understand these vulnerabilities are essential.

Evaluating the Utility of Procalcitonin and C-Reactive Protein to Predict Bacteremia in Children with Musculoskeletal Infections

Background:Musculoskeletal infections (MSKI; osteomyelitis, septic arthritis) are among the most common invasive bacterial infections in children, often associated with complications. Bacteremia precedes these complications; thus, early identification may prevent them. Acute inflammatory markers, C-reactive protein (CRP) and Procalcitonin (PCT) are often elevated in children with acute MSKI. PCT is understudied in children with MSKI. The primary goal of this study was to evaluate the utility of PCT and CRP in distinguishing children with MSKI with bacteremia vs. those without.&#x0D; Methods:Patients 6 months to 18 years with strong clinical suspicion of MSKI were prospectively enrolled at Riley Hospital for Children from July 2019 to May 2022 unless clinical evidence suggested an alternative diagnosis or if informed consent was not obtained. CRP was obtained at admission and PCT was collected within 96 hours of presentation to the hospital. Demographic data was recorded from electronic medical records. Two-sided P values of &lt;0.05 were considered statistically significant for univariate analysis and logistic regression.&#x0D; Results:Thirty-seven patients were enrolled, the majority being non-Hispanic white males (40.5%), median age of 8 years (IQR, 4-12). Median PCT in children with bacteremia was higher (0.41 ng/mL [IQR 0.14-0.8 ng/mL]) compared to those without (0.10 ng/mL [IQR 0.05-0.31 ng/mL]) (p=0.03). Median CRP in children with bacteremia was higher (13.7 mg/dL [IQR, 9.15-19.9]) compared to those without (4.1 mg/dL, [IQR 0.65-5.8]) (p&lt;0.01). Both PCT and CRP showed good ability to discriminate those with bacteremia from those without, with an area under the ROC of 0.75 (95% CI 0.56, 0.94) and 0.80 (95% CI 0.64, 0.95), respectively.&#x0D; Conclusions:Initial PCT and CRP demonstrated utility in detecting bacteremia in patients presenting with MSKIs. This study warrants further exploration into the usage of PCT and CRP as early predictors of bacteremia for more appropriate treatment and potentially fewer complications of these infections in pediatric patients.

Sex-specific racial and ethnic variations in short-term outcomes among patients with first or recurrent ischemic stroke: Paul Coverdell National Acute Stroke Program, 2016-2020

Background and purposeTo understand the association of sex-specific race and ethnicity on the short-term outcomes of initial and recurrent ischemic stroke events. MethodsUsing the Paul Coverdell National Acute Stroke Program from 2016-2020, we examined 426,062 ischemic stroke admissions from 629 hospitals limited to non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic patients. We performed multivariate logistic regression analyses to assess the combined effects of sex-specific race and ethnicity on short-term outcomes for acute ischemic stroke patients presenting with initial or recurrent stroke events. Outcomes assessed include rates of in-hospital death, discharge to home, and symptomatic intracranial hemorrhage (sICH) after reperfusion treatment. ResultsAmong studied patients, the likelihood of developing sICH after reperfusion treatment for initial ischemic stroke was not significantly different. The likelihood of experiencing in-hospital death among patients presenting with initial stroke was notably higher among NHW males (AOR 1.59 [95 % CI 1.46, 1.73]), NHW females (AOR 1.34 [95 % CI 1.23, 1.45]), and Hispanic males (AOR 1.57 [95 % CI 1.36, 1.81]) when compared to NHB females. Hispanic females were more likely to be discharged home when compared to NHB females after initial stroke event (AOR 1.32 [95 % CI 1.23, 1.41]). NHB males (AOR 0.90 [95 % CI 0.87, 0.94]) and NHW females (AOR 0.89 [95 % CI 0.86, 0.92]) were less likely to be discharged to home. All groups with recurrent ischemic strokes experienced higher likelihood of in-hospital death when compared to NHB females with the highest likelihood among NHW males (AOR 2.13 [95 % CI 1.87, 2.43]). Hispanic females had a higher likelihood of discharging home when compared to NHB females hospitalized for recurrent ischemic stroke, while NHB males and NHW females with recurrent ischemic stroke hospitalizations were less likely to discharge home. ConclusionsSex-specific race and ethnic disparities remain for short-term outcomes in both initial and recurrent ischemic stroke hospitalizations. Further studies are needed to address disparities among recurrent ischemic stroke hospitalizations.

Abstract C095: County-level disparities in lung cancer mortality rates by sex for non-Hispanic Blacks and non-Hispanic Whites residing in the United States

Abstract Background: Lung cancer is the deadliest cancer in the United States and mortality rates are highest for Non-Hispanic Black (NHB) and Non-Hispanic White (NHW) individuals compared to other racial groups. Additionally, lung cancer mortality rates are higher in men compared to women. However, county-level data for lung cancer mortality rates have not been studied in NHB and NHW populations stratified by sex. Further insight into county-level data disparity rates will provide stakeholders with tailoring and prioritizing community-based interventions to reduce lung cancer mortality disparities. Methods: Data from the 2015-2019 Centers for Disease Control and Prevention, United States Cancer Statistics were used to identify counties with age-adjusted lung cancer mortality rates for NHB and NHW males and females. Comparator groups were the general population for NHB and NHW, NHB vs. NHW females, and NHB vs. NHW males. Relative risk (RR) was used to determine the disparities in mortality rates between comparator groups in each county. A chi-square test was performed to identify the p-value between comparator groups. Results: Data were available for 336 counties across 40 states in the U.S. Overall, the majority of counties (N=172) demonstrated that NHBs had higher lung cancer mortality rates compared to NHWs with a mean RR of 1.24 (1.01-2.31). However, when stratified by sex, NHW females exhibited higher lung cancer mortality rates across the majority of counties (N=225) with a mean RR of 1.38 (1.01-2.7) compared to NHB females. North Carolina (N=25) and Texas (N=10) had the most counties experiencing disparities in lung cancer mortality rates between NHW and NHB females respectively. However, Dane County, Wisconsin had the highest disparity in mortality rates for NHB females compared to NHW females, RR:2.14 (p=0.001), and Middlesex County, Massachusetts had the highest disparity in mortality rates for NHW females compared to NHB females, RR:2.7 (p=0.002). NHB males exhibited higher lung cancer mortality rates across the majority of counties (N=230) with a mean RR of 1.34 (1.01-2.73) compared to NHW males. North Carolina had the most counties experiencing disparities in lung cancer mortality rates in NHW (N=13) and NHB (N=21) males. However, the District of Columbia had the highest disparity in mortality rates for NHB males compared to NHW males, RR: 2.73 (p=0.0001), and Petersburg County, Virginia had the highest disparity in mortality rates for NHW males compared to NHB males, RR:3.18 (p=&amp;lt;0.0001). Conclusion: Lung cancer mortality disparities are occurring throughout the United States for NHW and NHB females and males with the highest disparity in Middlesex County, Dane County, Petersburg County, and the District of Columbia respectively. However, consistent data highlighted a high prevalence of counties in North Carolina demonstrating lung cancer mortality disparities for all groups, except for NHB females. Future research and interventions are needed to understand the social and structural factors associated with mortality differences within these areas. Citation Format: Shanada Monestime.

Abstract B080: Examining racial differences in area-level factors associated with prostate cancer stage at diagnosis: A systematic review

Abstract In the United States, prostate cancer is the most diagnosed cancer and the second highest cause of cancer deaths in men. Despite the high survival rate for prostate cancer compared to other cancers, racial and ethnic disparities persist. Black males are more likely to be diagnosed at an advanced stage, with more aggressive forms, and have two-fold higher age-adjusted mortality rates than non-Hispanic White males. Research studies show that the stage at diagnosis is a critical prognostic factor for survival and access to quality health care. There is increasing evidence of an association between neighborhood area-level contextual factors (e.g., social and physical environments) and prostate cancer stage at diagnosis, but very few systematic reviews. This systematic review examined White and Black racial differences in the association between area-level factors and prostate cancer stage diagnosis in the United States. We systematically obtained relevant peer-reviewed articles published in English until August 30, 2022, from three databases: PubMed, Embase, and Scopus. The relevant studies included prostate cancer observational studies in adult men (18 years and older) conducted in the United States that measured one or more area-level factors at the level of a geographic unit (e.g., census tract, block group, and zip codes). We used the National Institutes of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies to review the internal validity of the final studies. The reviewers identified 41 articles with a stage at diagnosis as an outcome, of which 11 articles (26%) statistically examined White-Black differences for the association between stage at diagnosis and an area-level factor. Most of the final 11 studies (73%) used advanced stage (regional, distant/metastatic stage) as the primary indicator variable, and two studies looked at two different outcomes (e.g., localized/early stage and tumor aggressiveness). The observed area-level factors were grouped as social (62.5%), physical/built environment (18.8%), and health service determinants (18.8%). Neighborhood socioeconomic status (SES) or deprivation composite scores (12.5%) and poverty (12.5%) were the most area-level factors reported in the studies. There were differences in area-level factors associated with prostate cancer severity for Black and White males. Overall, the results showed that Black men were more likely to be diagnosed with advanced-stage or aggressive tumors if they resided in areas with low neighborhood SES, low environmental quality, and the highest deprived and racially segregated areas compared to Whites. The study summarized results from individual studies exploring the role of neighborhood area-level factors and prostate cancer stage racial disparities in the United States. Future studies can provide an understanding of the impact and mechanisms of the area-level social and physical environments in cancer disparities. Citation Format: Ifeanyi B. Chukwudozie, Elle R.

Abstract B138: Examining factors that contribute to racial and ethnic disparities in liver cancer within an EHR-based epidemiologic cohort linked to cancer registries

Abstract Background: Racial and ethnic disparities in HCC risk have been documented, but disparities across detailed racial and ethnic groups and the relative contribution of these factors to HCC risk across those groups has not been assessed. We assembled a pooled, EHR-based cohort linked to cancer registry data to study disparities in HCC risk among detailed racial and ethnic groups and to examine the relative contribution of known and putative HCC risk factors to disparities in risk. Methods: Adults with at least one in-person encounter in 2000-2017 within three healthcare systems, San Francisco Health Network, Sutter Health Northern California, and Kaiser Permanente Hawai’i, were linked to their respective population-based state cancer registries for data on incident HCC. We used EHR data to define 17 detailed racial and ethnic groups and other sociodemographic and clinical factors. We used Cox proportional hazards regression with age as the timescale to examine racial/ethnic disparities in HCC risk with sex-specific models adjusted for length of active follow-up and with underlying stratification by site, birth cohort, baseline year and number of encounters. We calculated sex-specific hazards and population attributable fractions (PAFs) of HCC risk factors among racial/ethnic groups (e.g., smoking, hepatitis infections, metabolic syndrome). Results: The pooled cohort contained data on 4,249,671 adults followed a median of 6.8 years; 55% were female, and 2,916 had incident HCC. Compared to non-Hispanic White males, Vietnamese American males had greater risk of HCC (HR: 7.42; 95% CI: 4.25, 12.96) as did American Indian/Alaska Native, Black, Chinese American, Hispanic, Native Hawaiian, and Pacific Islander males, and those of multiple races or ethnicities. Among females, every group except for American Indian/Alaska Native, Asian Indian American, and Pacific Islander females had greater risk of HCC compared to the non-Hispanic White group; HRs ranged from 1.68 (1.01, 2.78) among Filipino to 6.38 (2.79, 14.55) among Vietnamese American females. Risk of HCC according to clinical risk factors was similar for males and females; however, the PAF of HCC for alcohol disorders was much higher for females (43%) than males (2%). Analyses by racial/ethnic group are ongoing, but variation in factor-specific risk of HCC was observed in preliminary analyses; for example, only non-Hispanic White and Asian American males had greater risk of HCC with metabolic-associated fatty liver disease and ever-smoking. Conclusions: Analysis of a large EHR-based cohort linked with cancer registry data yields additional information on cancer disparities across detailed racial and ethnic groups and may benefit efforts to identify targets for intervention. Our results indicate disparities in HCC risk across detailed racial and ethnic groups traditionally aggregated into larger groups (e.g., Asian American/Pacific Islander). Variation in the PAF of HCC for known risk factors suggest that the most impactful prevention efforts may require tailoring to the target populations. Citation Format: Mindy C. DeRouen, Alison J.

Prostate-specific antigen testing rates in high-risk populations: results from the All of Us Research Program

BackgroundEarly detection of prostate cancer using prostate-specific antigen (PSA) remains controversial and disparities in the receipt of prostate cancer screening persist in the US. We sought to examine disparities in PSA testing rates among groups with higher prostate cancer risk and differential access to healthcare.MethodsWe identified a cohort of 37,706 males within the All of Us Research Program without a history of prostate cancer between the ages of 40 and 85 at time of enrollment (2017–2021). Incidence rate ratios (IRR) for the number of PSA tests received during follow-up through December 2021 were estimated using age- and multivariable-adjusted negative binomial regression models. PSA testing frequencies in the cohort were compared with population-based estimates from the 2020 Behavioral Risk Factor Surveillance System (BRFSS).ResultsA total of 6,486 males (17.2%) received at least one PSA test over the course of follow-up. In multivariable-adjusted models, non-Hispanic Black males received PSA tests at a 17% lower rate (IRR = 0.83, 95% CI 0.76, 0.90) than non-Hispanic White males. Higher educational attainment, higher annual income, having self-/employer-purchased insurance, having a spouse or domestic partner, and having a family history of prostate cancer were all associated with higher rates of PSA testing. The proportion of males ages 55 to 69 who received a PSA test within two years was lower in All of Us (12.4%, 95% CI 11.8–13.0%) relative to population-based estimates from the BRFSS (35.2%, 95% CI 34.2–36.3%).ConclusionAbsolute PSA testing rates in All of Us were lower than population-based estimates, but associations with PSA testing in the cohort mirrored previously reported disparities in prostate cancer screening. These findings highlight the importance of addressing barriers to care in order to reduce disparities in cancer screening.

Money Worries: Examining Demographic Difference in Financial Anxiety

We identify key demographic groups that suffer the most from financial anxiety. Identifying demographic groups that suffer the most from financial anxiety will aid in finding policy avenues to improve financial outcomes. With data from the 2018 National Financial Capability Study and Ordinary Least Square regressions, we find that females and those individuals with some college are the most financially anxious. In addition, the separated or divorced worry more than the married, those with children worry more than the childless, and White non-Hispanics worry more than other racial/ethnic groups. Analyses of gender subsamples show that black non-Hispanic males worry more than White non-Hispanic males, while the result of the female subsample is the opposite. The findings of this study have major policy implications, and more research is needed to determine how to best measure financial anxiety and solutions to reduce financial anxiety. Financial counseling and planning professionals can target groups that are most financially anxious. We recommend that financial education include a curriculum to educate and prepare individuals for financial anxiety and its implication on financial outcomes.

Implementing methods in the ELEGANCE registry to increase diversity in clinical research

ObjectiveWomen and underrepresented minorities (URMs) who are at an increased risk of presenting with severe peripheral artery disease (PAD) and have different responses to treatment compared with non-Hispanic White males yet are underrepresented in PAD research. MethodsELEGANCE is a global, prospective, multi-center, post-market registry of PAD patients treated with drug-eluting device that aims to enroll at least 40% women and 40% URMs. The study design incorporates strategies to increase enrollment of women and URMs. Inclusion criteria are age ≥18 years and treatment with any commercially available Boston Scientific Corporation drug-eluting device marketed for peripheral vasculature lesions; exclusion criterion is life expectancy <1 year. ResultsOf 750 patients currently enrolled (951 lesions) across 39 sites, 324 (43.2%) are female and 350 (47.3%) are URMs (21.6% Black, 11.2% Asian, 8.5% Hispanic/Latino, and 5.3% other). Rutherford classification is distributed differently between sexes (P = .019). Treatment indication differs among race/ethnicity groups (P = .003). Chronic limb-threatening ischemia was higher for Black (38.3%) and Hispanic/Latino (28.1%) patients compared with non-Hispanic White (21.8%) and Asian patients (21.4%). De-novo stenosis was higher in Asian patients (92.3%) compared with Black, non-Hispanic White, and Hispanic/Latino patients (72.2%, 68.7%, and 77.8%, respectively; P < .001). Mean lesion length was longest for Black patients (162.7 mm), then non-Hispanic White (135.2 mm), Asian (134.8 mm), and Hispanic/Latino patients (128.1 mm; P = .008). ConclusionsAnalyses of data from the ELEGANCE registry show that differences exist in baseline disease characteristics by sex and race/ethnicity; these may be the result of other underlying factors, including time to diagnosis, burden of undermanaged comorbidities, and access to care.
