Incident cardiovascular disease risk among older Asian, Native Hawaiian and Pacific Islander liver cancer survivors

BackgroundCardiovascular disease (CVD) is a significant global health concern, particularly among Asian, Native Hawaiian, and Pacific Islander (ANHPI) communities that face unique health challenges. Liver cancer disproportionately affects ANHPI populations and has intricate associations with CVD risks due to shared pathophysiological mechanisms and metabolic disturbances. However, the specific CVD risk profile of ANHPI liver cancer patients remains poorly understood. MethodsUsing Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified and matched 1150 ANHPI and 2070 Non-Hispanic White (NHW) liver cancer patients diagnosed between 2000 and 2017. We used the Fine-Gray sub-distribution hazard model to estimate hazard ratios (HRs) and 95 % confidence intervals (95 % CIs) for CVD risks, including ischemic heart disease (IHD), heart failure, and stroke, among ANHPI liver cancer patients compared to NHW counterparts and among ANHPI subgroups. ResultsANHPI liver cancer patients demonstrated a lower risk of IHD compared to NHW counterparts (HR, 0.65, 95 % CI, 0.50, 0.86), aligning with broader trends. Subgroup analysis revealed notable heterogeneity within ANHPI populations, with Southeast Asian (HR, 0.65, 95 % CI, 0.42, 1.00) and Chinese patients (HR, 0.53, 95 % CI, 0.33–0.83) exhibiting lower IHD risks compared to their NHW counterparts. However, Native Hawaiian and Pacific Islander liver cancer patients showed elevated risks of heart failure (HR, 3.16, 95 % CI, 1.35–7.39) and IHD (HR, 5.64, 95 % CI, 2.19–14.53) compared to their Chinese counterparts. ConclusionOur study highlights the complexity of CVD risks among ANHPI liver cancer patients. Addressing these disparities is crucial for improving cardiovascular outcomes and reducing the burden of CVD among ANHPI liver cancer patients.

Race, Gender, and Faculty Retention in Academic Medicine.

Poor retention may be associated with lack of faculty diversity in academic medicine. To examine differences in faculty retention by gender, degree type, and race and ethnicity using data from US medical schools. This cohort study analyzed data from 155 medical schools for 1978 to 2021, which were obtained from the Association of American Medical Colleges. Retention rates were calculated by gender, race and ethnicity, and degree type. Time to attrition was estimated using Kaplan-Meier curves and adjusted Cox proportional hazards models were used to examine the differences in retention by gender and race. Data were analyzed from March 2021 to November 2022. The duration of continuous employment in academic medicine and variations in retention based on gender, race, ethnicity, and terminal degree. Among 390 766 faculty members (232 829 [59.6%] men; 1190 American Indian, Alaska Native, Native Hawaiian, or Pacific Islander [0.3%]; 72 490 Asian [18.6%]; 14 920 Black [3.8%]; 20 345 Hispanic, Latino, of Spanish origin, or multirace Hispanic [5.2%]; 251 670 non-Hispanic White [64.4%] participants; and 30 151 [7.7%] other race), 259 628 (66.4%) had MD or MD-equivalent terminal degrees. Women left academic medicine a median of 1 year earlier (median retention, 8.33 years; 95% CI, 8.18-8.41 years) than men (median retention, 9.35 years; 95% CI, 9.25-9.42 years). Compared with White faculty (median retention, 9.91 years; 95% CI, 9.83-9.92 years), multiracial and faculty of other races had the lowest retention (median retention, 5.42 years; 95% CI, 5.33-5.55 years), followed by Alaska Native, American Indian, Native Hawaiian, and Pacific Islander (median retention, 6.00 years; 95% CI, 5.62-6.62 years), Black (median retention, 7.78 years; 95% CI, 7.50-8.00 years), Asian (median retention, 8.00 years; 95% CI, 8.00-8.11 years) and Hispanic faculty (median retention, 9.00 years; 95% CI, 8.75-9.16 years). Women faculty in the 1970s were 20% more likely than men to leave academia, whereas women in the 2010s had no greater risk of leaving, mainly due to a decline in retention of men. Gender differences in faculty retention have decreased in the most recent decade; however, men had lower retention compared with earlier cohorts. In this study, faculty who were underrepresented in medicine left academic medicine a median of 1 to 4 years earlier than White faculty. Greater attrition among men and women for recent cohorts suggests that enhanced retention efforts are imperative to maintain an experienced and diverse faculty.

Abstract 4112952: Developing culturally informed materials to enhance Native Hawaiians' and Pacific Islanders’ participation in clinical trials

Background: Native Hawaiians and Pacific Islanders (NHPI) suffer disproportionately from cardiometabolic disorders and are underrepresented in related clinical trials, limiting our ability to control these disorders for this population. We identified recruitment and retention barriers (complicated clinical language) and facilitators (relationship-building opportunities). Addressing recruitment and retention barriers and facilitators can increase NHPI representation in clinical trials. Goal: To develop culturally informed, educational videos and infographics to improve NHPI trust and attitudes toward research and recruitment and retention in clinical trials. Methods: The videos and infographics are based on focus group data with NHPI past clinical trial participants or staff. The videos focus on recruitment. The infographics focus on recruitment and retention. The videos address the complicated clinical language and hesitancy in disclosing information while leveraging trial outcomes relevant to NHPI health concerns and cultural inclusiveness. The infographics build on the video content. Facilitators include relationship-building opportunities, seeking healthier outcomes for future generations, relationship-building opportunities, and sharing and learning opportunities provided in clinical trials. Results: The Co-Principal Investigators, NHPI clinical trial participants, and NHPI researchers and clinicians contributed to the videos. We created a 5-minute and a 10-minute video. The videos provide 1) an overview of clinical research, 2) considerations for participating in clinical trials, and 3) reasons to participate. Researchers present the first 2 topics, while past participants provide testimonials for the third topic. The 8 infographics include 1) an overview of clinical research, 2) the importance of randomization, 3) research benefits from NHPI participation, 4) the importance of a control group, 5) clinical trial outcomes, 6) individual benefits from research participation, 7) community benefits from research participation, and 8) trust in research. Discussion: We will test the impact of these materials on trust and attitudes towards research and recruitment and retention among NHPI in a randomized clinical trial (RCT). Half of the participants (n=104) will be recruited using traditional strategies and half (n=104) using our novel strategy. Rigorous qualitative (interviews with participants) and quantitative (retention rates) analysis will be conducted.

Abstract 4136636: Analysis of Racial Disparities in the Training Path to Cardiology: Trends from 2012 to 2022

Introduction: Substantial evidence indicates that racial and ethnic diversity among the physician workforce bridges cultural gaps and improves patient care. Trends in racial diversity across the full training pipeline from undergraduate to practicing cardiologist are not yet well-characterized. Aims: We analyze racial disparities at each stage of training towards becoming a practicing cardiologist, and identify changes in these disparities between 2012 and 2022. Methods: We conducted a retrospective analysis of data specifying the racial composition of medical trainees acquired from the Association of American Medical Colleges, Accreditation Council for Graduate Medical Education, and Electronic Residency Application Service. Population data was acquired from the US Census Bureau. We computed the representation quotient (RQ) for each racial group at each stage to compare representation among the trainees or physicians to age-matched segments of the US population. Results: RQ decreases from undergraduate to active cardiologist for African Americans (0.719 to 0.314), Hispanics (0.660 to 0.359), American Indians (0.551 to 0.221), and Native Hawaiians (1.121 to 0.512). The lowest RQs of 0.133 and 0.137 were observed for American Indian active internal medicine residents and cardiology fellows, respectively. Racial disparities in medical education declined between 2012 and 2022, with RQs increasing from 0.541 to 0.735 for African American medical school matriculants and from 0.444 to 0.578 for Hispanic medical school matriculants. Similar increases were seen in the active cardiologist population for African Americans (2013 RQ: 0.227, 2022 RQ: 0.342) and Hispanics (2013 RQ: 0.283, 2022 RQ: 0.375). Conclusion: While racial diversity in the cardiology training pipeline has increased over the last decade, significant disparities persist for under-represented minorities. Addressing these barriers will help achieve a cardiology workforce reflective of the diverse population it serves.

A cross sectional analysis of residents by race/ethnicity and specialty from 2020-2023

BackgroundMinorities are underrepresented in all areas of medical education relative to the United States general population, and minority physicians are more likely to practice in disadvantaged areas and in primary care settings. Many individual and structural factors contribute to this discrepancy. We aimed to demonstrate how resident race/ethnicity representation differs across the various resident specialties. MethodsWe used publically available data from the Association of American Medical College's Report on Residents data series and averaged the four academic years from 2019 to 2020 through 2022-2023. We then calculated the odds ratio (OR) of self-reported race/ethnicity (alone and in combination) in thirty-four specialties. ResultsAcross the four-year study period, there were, on average, 147026 unduplicated resident trainees. The average number of duplicated residents by self-identified ethnic category (alone and in combination) include: American Indian or Alaska Native (839, 0.6%), Asian (31627, 21.5%), Black or African American (7935, 5.4%), Hispanic, Latino, or of Spanish Origin (10900, 7.4%), Native Hawaiian or Other Pacific Islander (296, 0.2%), White (76289, 51.9%), Other (4879, 3.3%), Unknown (522, 0.4%), and Non-US Citizens (23914, 16.3%). Across race/ethnicity, there are differences in ORs of representation in different specialties. Key findings include high representation in Public Health and Preventative Medicine by Black and African American (OR=3.7) and Native Hawaiian (OR=2.6) residents, and Family Medicine in Native Americans (OR=1.9), Native Hawaiian (OR=1.7), Black (OR=1.5), and Hispanic (OR=1.3) residents. Psychiatry also had high ORs of representation in minority residents. ConclusionThis study illustrates relative resident ethnic representation across training specialties. Minorities ethnicities were more likely to be represented in primary care and public health domains. This has implications for creating a physician workforce suitable to serve the United States Population.

Posttraumatic stress disorder in diverse populations: Testing for assessment bias in a nationally representative sample.

A growing body of research has emerged to characterize differences in posttraumatic stress disorder (PTSD) symptom presentations in individuals from diverse racial and ethnic groups. However, less research has examined if these observed differences can be attributed to bias within PTSD assessments. Knowledge about potential bias in PTSD assessment is essential for interpreting group differences. If PTSD assessments do not perform similarly across diverse demographic groups, then observed differences may be artificial products of inaccurate measurement, new assessments could be required for individuals from different demographic groups, and we would be unable to accurately detect PTSD treatment effects in patients from diverse groups. We evaluated PTSD assessment bias through tests of measurement invariance for the semistructured, clinician-administered AUDADIS-5 diagnostic assessment of participants in the National Epidemiologic Survey on Alcohol and Related Conditions-III. Participants included those who reported having experienced at least one potentially traumatic event in their lifetime (N = 23,936). Measurement invariance was assessed for participants who identified from several demographic groups (Asian, Native Hawaiian, or Pacific Islander; Hispanic; American Indian/Alaskan Native; and Black) compared to participants who identified as White (non-Hispanic). Overall, PTSD assessment was largely invariant across groups, while small amounts of measurement invariance were detected that can inform future research and clinical adaptations. This work validates prior research that relies on a common conceptualization of PTSD, and it provides several paths for future improvement in research and clinical practice.

Disparities in cancer stage shifts associated with the COVID-19 pandemic in California, 2020-2021.

The COVID-19 pandemic and associated shutdowns disrupted healthcare access and resulted in decreased cancer screenings. Cancer diagnosis delays have concerning downstream effects on late-stage cancer, especially for marginalized populations. The study population included 349,458 adults in the California Cancer Registry diagnosed with cancer between January 2019-December 2021, during which California experienced two stay-at-home orders. We examined the percentage of late-stage (III-IV) cancer diagnoses across five periods: Pre-Pandemic (January 2019-February 2020), Shutdown #1 (March-June 2020), Post-Shutdown #1 (July-November 2020), Post-Shutdown #2 (December 2020-March 2021), and Post-Vaccine Rollout (April-December 2021). To examine the association between time-period and late-stage diagnoses, we conducted a multivariable log binomial regression model adjusted for sociodemographic and neighborhood factors. The percentage of late-stage cancer diagnoses increased during Shutdown #1 (+5.2%) and returned to baseline Post-Vaccine Rollout. Groups with notably higher increases in the percentage of late-stage cancer (vs. overall population) during Shutdown #1 include: Pacific Islander (+13.7%), Thai (+11.2%), Chinese (+8.1%), Native Hawaiian (+7.4%), Filipino (+6.6%), and uninsured (+7.4%). Uninsured (vs. private insurance) (PR: 1.41), low neighborhood SES (nSES) (vs. high) (PR: 1.19), and racial and ethnic minoritized groups (vs. NH White) (PR's: 1.04-1.19) had higher likelihood for late-stage cancer diagnosis. The pandemic exacerbated late-stage cancer disparities for racial and ethnic minoritized groups, underinsured, and low nSES communities in California (2020-2021). Interventions to improve cancer screening must be focused on racial and ethnic minoritized, underinsured, and low nSES communities, as they are likely to be more vulnerable to healthcare disruptions like the pandemic.

Representation of Native Hawaiian and Pacific Islander Individuals in Clinical Trials

Having diverse participants in clinical trials ensures new drug products work well across different demographic groups, making health care safer and more effective for everyone. Information on the extent of Native Hawaiian and Pacific Islander participation in clinical trials is limited. To examine representation of Native Hawaiian and Pacific Islanders in clinical trials leading to the first US Food and Drug Administration (FDA) approvals for the 10 drug products with the top worldwide sales forecasts in 2024. Cross-sectional secondary analysis of existing data from clinical trials that took place from 2006 to 2021 in the US. All clinical trials that were included in the FDA first approval application for the 10 drug products were evaluated in this study. Data were analyzed from February to August 2024. Participation in a clinical drug trial. Comparison of the proportion of Native Hawaiian and Pacific Islander participation in clinical trials for the 10 drug products with top sales forecasts in 2024 to the Native Hawaiian and Pacific Islander population proportion. In this cross-sectional study of 139 062 individuals, Native Hawaiian and Pacific Islander participation in clinical trials for the 10 drug products with top sales forecasts was either unknown or low. For 6 of the 10 drug products (60%), the number of Native Hawaiian and Pacific Islander participants was not documented. All trials that reported Native Hawaiian and Pacific Islander participation had fewer Native Hawaiian and Pacific Islander participants than would be expected based on their US population proportion, with 2 of the differences being statistically significant. Of the trials that disaggregated Native Hawaiian and Pacific Islander participants from other racial groups, the number of Native Hawaiian and Pacific Islander participants was 8 for risankizumab-rzaa (0.38% of participants vs 0.49% of the population; percentage point difference, -0.11%; 95% CI, -0.37% to -0.15%), 7 for bictegravir/emtricitabine/tenofovir alafenamide (0.38% of participants vs 0.49% of the population; percentage point difference, -0.10%; 95% CI, -0.39% to 0.18%), 27 for 4vHPV/9vHPV (0.15% of participants vs 0.46% of the population; percentage point difference, -0.31%; 95% CI, -0.37% to -0.26%), and 90 for BNT162B2 COVID-19 vaccine (0.20% of participants vs 0.52% of the population; percentage point difference, -0.32; 95% CI, -0.36% to -0.27%). In this cross-sectional study, limited documentation and participation of Native Hawaiian and Pacific Islander individuals in clinical trials for drug products with top sales forecasts was found. This is especially concerning because Native Hawaiian and Pacific Islander individuals have a higher risk than other racial groups for type 2 diabetes, cancer, and several other conditions the products examined in this study treat. Given the importance of enrolling Native Hawaiian and Pacific Islander participants in clinical trials, sites should be established in key geographic regions, such as Hawai'i, and postmarket studies should be conducted within Native Hawaiian and Pacific Islander populations.

Sociodemographic Disparities in 1-Year Outcomes of Children With Community-Acquired Acute Kidney Injury

Racial disparities have been identified in pediatric community-acquired acute kidney injury (CA-AKI), and they are associated with increased risk of child mortality, morbidity, and progression of kidney disease. To assess clinical outcomes at 1 year among children with CA-AKI, stratified by age, race, and ethnicity. This retrospective cohort study is a population-based analysis of deidentified, aggregated electronic health record data collected by 61 large health care organizations from 2003 to 2023 and accessed through the TriNetX platform. Outcomes were assessed at 1 year after a CA-AKI episode. Participants included pediatric patients (aged <18 years) with AKI. Data were accessed in January 2024. A diagnosis of CA-AKI and sociodemographic factors such as race, ethnicity, and age, as reported in electronic health records. The primary end point of this study was to assess differences in clinical outcomes within 1 year of an episode of CA-AKI, including all-cause emergency department (ED) visits, intensive care unit (ICU) admissions, mechanical intubation and ventilation, and mortality. Risk was compared between White children and Asian (including Asian, Native Hawaiian, and Other Pacific Islander), Black, and Hispanic children, stratified by age group. Measures of association, Cox proportional hazard analyses, and Kaplan-Meier survival curves were performed within the TriNetX Advanced Analytics Platform between racial and ethnic groups for each analysis. From the total sample of 18 152 children, those with hospital-acquired AKI, chronic kidney disease, end-stage kidney failure, or dialysis dependence were excluded, leaving a final cohort of 17 125 children (mean [SD] age, 11.2 [5.2] years; 9424 male [55.3%]). Eligible patients were divided into racial and ethnic groups as follows: non-Hispanic Asian, 1169 children (6.5%); non-Hispanic Black, 4636 children (27.3%); Hispanic, 1786 children (10.2%); and non-Hispanic White, 9534 children (55.9%). Patients were further subdivided into groups aged 0 to 9 years (546 Asian children, 1675 Black children, 689 Hispanic children, and 3340 White children) and 10 to 18 years (623 Asian children, 2961 Black children, 1091 Hispanic children, and 6104 White children). Within 1 year of CA-AKI diagnosis, compared with White children, Black children experienced greater rates of ED visits (hazard ratio [HR], 1.53; 95% CI, 1.40-1.67), ICU admissions (HR, 1.31; 95% CI, 1.16-1.47), mechanical ventilation (HR, 1.33; 95% CI, 1.13-1.56), and all-cause mortality (HR, 1.27; 95% CI, 1.09-1.48), as well as the greatest risk for composite outcomes (HR, 1.43; 95% CI, 1.33-1.53). Hispanic children experienced greater rates of ED visits (HR, 1.40; 95% CI, 1.21-1.62) and the greatest risk of all-cause mortality (HR, 1.66; 95% CI, 1.31-2.09), whereas Asian children experienced greater rates of mechanical ventilation (HR, 1.69; 95% CI, 1.26-2.27), compared with White children. Black and Hispanic children aged 0 to 9 years were at greatest risk of experiencing poor clinical outcomes. Black children had a 11.41% lower survival probability and Hispanic children had a 7.14% lower survival probability compared with White children after an initial ED encounter. Among children with an identified episode of CA-AKI diagnosed in an ED, within 1 year, Black and Hispanic children had a poorer survival probability compared with White children. Future studies are needed to understand these disparities and improve awareness and follow-up after emergency care.

Culturally-relevant physical activity for public health promotion: global evidence synthesis

Abstract Background The WHO has noted the importance of cultural insights for health. Culturally-relevant physical activity has a growing evidence base in many regions and specific populations, but the scope and scale for global health promotion is underexplored. Methods A multinational expert team used a critical literature review method to: (1) define culturally-relevant physical activity; (2) delineate relevant characteristics supporting inclusion in population-level health promotion and surveillance; and (3) provide agenda setting in research, policy, and practice from a global public health promotion perspective. The critical review method, which evaluates rather than summarizes literature, was chosen as the research evidence is complex, broad, and has not been synthesized previously from this perspective. Results Culturally-relevant physical activity was defined as practices that include physical activity based on a population’s cultural customs. These can be Indigenous (e.g., hula, an Indigenous dance of Native Hawaiians) or regional (e.g., Shota (Shotë), an Albanian folk dance). Practices have shared characteristics that support multi-dimensional value for health, engagement, and healing. These include a collectivist, intergenerational component, passed from elders and shared forward with children as part of a community. Many have foundations in nature, a strength for health and wellbeing in green and blue spaces. Many include traditional art, clothing, accessories, and music with deep significance, including care for the tools and location of practice (e.g, drums, boats, land). Many practices would not be captured in harmonized public health surveillance systems despite their value. From this synthesis, research hypotheses were created and next steps proposed. Conclusions This evidence synthesis supports engagement, planning, uptake, policy, surveillance, and study of culturally-relevant physical activity for public health promotion locally and globally. Key messages • An important strength of culturally-relevant physical activity is that it is context and population specific. However, this may hide the scope and scale of the existing evidence supporting this work. • This evidence synthesis confirms how culturally-relevant physical activity is valuable globally across shared assets in research and practice, supporting next steps for public health promotion.

Surfing a culturally-relevant physical activity: a new wave for health promotion

Abstract Background Surfing originated with Native Hawaiians prior to Western contact. It has since gained worldwide popularity, with an estimated 50 million surfers globally, and recently became an official Olympic sport. Associations have been reported between surfing and mental and physical health outcomes, greater community cohesion, and stronger intra-family relationships. Despite this evidence, surfing is deeply understudied in the context of health promotion. Purpose Surfing was analyzed from a mixed methods perspective to explore factors associated with lifetime participation and current engagement, including gender, race/ethnicity, chronic disease, social context, meaning, and average time of participation. Methods Hawai’i adult residents (n = 1066) completed an online or phone questionnaire. Modified Poisson regression models were fit for lifetime engagement and having a self-reported chronic disease, adjusting for primary race/ethnicity, age, gender, and education. Results Over their lifetime, 42% of respondents (50% men and 37% women) had participated in surfing. Engagement was highest during youth and young adulthood, and decreased with age, yet trends varied notably by race/ethnicity, gender, and generation. Lifetime surfing engagement was significantly related to lower likelihood of diabetes (aPR:0.72; 95%CI:0.56-0.92;p=0.009). Individuals who regularly participated in surfing typically did so with friends (78%) or family (61%); average surfing session duration was 209 minutes. Qualitative results revealed the relevance of surfing across levels of influence for health and wellbeing from physical fitness to community, culture, history and spirituality. Conclusions This work provides insights on the health promotion opportunities of surfing across the life-course and populations, including disease prevention and management. This study has implications for planning and policy locally and globally to achieve optimal community and planetary health. Key messages • Surfing is not only a sport for elite athletes, but also an activity that can support community and individual health and wellbeing in many populations over the lifespan. • Promotion of surfing and public ocean access can support multidimensional influences for wellbeing and should be a focus of cross sector collaborations for optimal community and planetary health.

The cultural adaptation and psychometric evaluation of the Mothers on Respect Index for Native Hawaiians and Pacific Islanders

BackgroundNative Hawaiian and Pacific Islanders (NHPI) are disproportionately burdened by pregnancy-related deaths in the United States and have the lowest engagement in prenatal care compared to all other US racial groups. Aside from access barriers, studies suggest that NHPI face challenges with patient-clinician communication, perceived discrimination, and cultural conflicts within healthcare settings. This paper describes the cultural adaptation of the 14-item Mothers On Respect index for NHPI, originally developed by Vedam et al. (2017) for diverse communities in British Columbia, Canada, and reports the findings of the preliminary psychometric assessment of the adapted measure.MethodsData from 26 interviews with NHPI women, expert, and cognitive interviews were conducted to inform the adaptation. An online survey was administered to a sample of 90 NHPI women to assess construct validity, convergent validity, and internal reliability of the adapted measure using exploratory and confirmatory factor analyses.ResultsThe adaptation resulted in substantial changes to the original measure, mainly by the addition of items related to ‘feeling cared for by and connected to the provider’ and ‘perceived threats hindering communication.’ The psychometric analyses identified a three-factor structure for the culturally adapted index and confirmatory factor analyses were employed to refine the measure. The result was a 25-item index with acceptable goodness of fit indices, high internal reliability (Cronbach’s alpha of 0.96, 95% CI = .94-.97) and convergent validity with a related scale. Overall, participants in this sample indicated high levels of respectful care; however, people who received < 8 prenatal care visits had significantly lower ratings on average.ConclusionsOur findings suggest that the elements valued by NHPI are not fully captured in existing measures of respectful maternity care. Efforts to assess more discrete aspects of the patient-provider relationship for culturally distinct and racialized groups could help improve the quality of care and advance equity in maternal and perinatal health marginalized communities.

The role of ethnic enclaves and neighborhood socioeconomic status in invasive breast cancer incidence rates among Asian American, Native Hawaiian, and Pacific Islander females in California.

Few studies have examined whether the incidence rates of invasive breast cancer among Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations differ by the neighborhood social environment. Thus, we examined associations of ethnic enclave and neighborhood socioeconomic status (nSES) with breast cancer incidence rates among AANHPI females in California. A total of 14,738 AANHPI females diagnosed with invasive breast cancer in 2008-2012 were identified from the California Cancer Registry. AANHPI ethnic enclaves (culturally distinct neighborhoods) and nSES were assessed at the census tract level using 2007-2011 American Community Survey data. Breast cancer age-adjusted incidence rates and incidence rate ratios (IRRs) were estimated for AANHPI ethnic enclave, nSES, and their joint effects. Subgroup analyses were conducted by stage of disease. The incidence rate of breast cancer among AANHPI females living in lowest ethnic enclave neighborhoods (quintile (Q)1) were 1.21 times (95% Confidence Interval (CI) 1.11, 1.32) that of AANHPI females living highest ethnic enclave neighborhoods (Q5). In addition, AANHPI females living in highest vs. lowest SES neighborhoods had higher incidence rates of breast cancer (Q5 vs. Q1 IRR = 1.30, 95% CI 1.22 to 1.40). The incidence rate of breast cancer among AANHPI females living in low ethnic enclave + high SES neighborhoods was 1.32 times (95% CI 1.25, 1.39) that of AANHPI females living in high ethnic enclave + low SES neighborhoods. Similar patterns of associations were observed for localized and advanced stage disease. For AANHPI females in California, incidence rates of breast cancer differed by nSES, ethnic enclave, when considered independently and jointly. Future studies should examine whether the impact of these neighborhood-level factors on breast cancer incidence rates differ across specific AANHPI ethnic groups and investigate the pathways through which they contribute to breast cancer incidence.

An Equitable Communication and Dissemination Model for Linking Culturally Diverse Communities to COVID-19 Services.

In 2020, the Office of Minority Health (OMH) funded the establishment of the National COVID-19 Resiliency Network (NCRN) to engage priority communities that included African American, American Indian, Alaska Native, Asian, Hispanic, Native Hawaiian, and Pacific Islander persons to aggregate culturally relevant messages, education tools, and national data sources. A mobile application and Web site supported a culturally sensitive, equity-focused communication and dissemination initiative to link communities to COVID-19 clinical, social, and behavioral health services to address health determinants.

Did Biden-Harris’s reforms on the Paycheck Protection Program reduce racial disparities in lending?

AbstractIntroduced under the Trump-Pence Administration, the Paycheck Protection Program (PPP) provided short-term relief loans to small American businesses during the peak of the Coronavirus pandemic. The initial design of the PPP faced significant criticism from researchers due to racial disparities, among other issues, in its lending process. Minority groups received smaller PPP loan amounts during the original two tranches released in 2020. To increase equitable access for all, in February 2021 the Biden-Harris Administration enforced swift changes to the initial PPP aimed at favouring access to PPP loans for minority-owned small businesses that had been disadvantaged by the program’s original design under the Trump-Pence Administration. By exploiting a granular dataset of 1,759,270 PPP loans granted between Q2 2020 and Q2 2021 and by implementing a difference-in-differences approach (DID), this paper provides novel evidence on the effectiveness of the Biden reforms in reducing racial disparities within the Paycheck Protection Program. Indeed, we observe a significant increase in the volume of PPP loans granted to minority-owned businesses in the period following the Biden-Harris Administration’s reforms. Furthermore, among different minority groups, the reforms appear most effective for Native American minority groups (including American Indians, Alaska Natives, Native Hawaiians and/or Other Pacific Islanders), followed by Black Americans and Asian business owners. Our findings offer novel contributions to the existing literature on institutional discrimination, particularly regarding the initial PPP design. Our findings are especially valuable for policy makers as they underscore the importance of radical changes in addressing racial disparities. Our paper also offers evidence of how a public credit guarantee program should be designed to empower and promote economic inclusion for all, regardless of ethnicity, aligning with the UN’s Sustainable Development Goals.

Treatment and Survival Disparities in Asian Americans With Hepatocellular Carcinoma

Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in the United States and globally. The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) population has often been studied as one homogenous cohort despite its heterogeneity. We aim to understand differences in treatment modality and mortality among AANHPI patients with early-stage HCC. Methods: The National Cancer Database was queried between 2004 and 2019. Patients with early-stage HCC eligible for liver transplantation (LT) were included. AANHPI patients were further disaggregated into subgroups, and non-Hispanic White (NHW) patients were included as reference. χ2 was used for categorical variables and the Student t test was used for continuous variables. Survival curves were generated using Kaplan-Meier estimates. Results: A total of 3039 (8.5%) AANHPI and 32,845 (91.5%) NHW were included. Among the AANHPI, 1368 (45.0%) were East Asian (EA), 1229 (40.4%) were Southeast Asian (SEA), 302 (9.9%) were South Asian (SA), and 140 (4.6%) were Native Hawaiian and other Pacific Islander (NHPI). Compared with NHW, AANHPI patients were less likely to undergo LT but had lower mortality. When disaggregated, SA patients were more likely to receive LT (HR: 2.70), and SEA (HR: 1.43) and NHPI (HR: 1.90) patients had higher mortality when compared with EA, all P&lt;0.01. Conclusions: AANHPI with early-stage HCC had better survival as a cohort. However, when disaggregated, there were notable disparities among different subgroups. AANHPI represents an incredibly diverse group of individuals, and it is imperative for physicians, researchers, and policy makers to appreciate the true heterogeneity of this population.

Amygdala Subregion Volumes and Apportionment in Preadolescents - Associations with Age, Sex, and Body Mass Index.

The amygdala, a key limbic structure, plays a critical role in emotional, social, and appetitive behaviors that develop throughout adolescence. Composed of a heterogeneous group of nuclei, questions remain about potential differences in the maturation of its subregions during development. To characterize the associations between developmental variables and amygdala subregion volumes during preadolescence. Cross-sectional Adolescent Brain Cognitive Development (ABCD®) Study data was collected from 3,953 9- and 10-year-old children between September 1, 2016, and October 15, 2018. Data analysis was conducted between June 1, 2023, and July 30, 2024. Using the CIT168 Amygdala Atlas, nine amygdala subregion volumes were quantified from high-quality MRI scans. Linear mixed-effects models were used to examine the effects of age, sex, pubertal stage, and body mass index z-score (BMIz) on subregion volumes and their relative apportionment within the amygdala. The study population consisted of 3,953 preadolescents (mean [SD] age, 120 [7.41] months; 1,763 [44.6%] female; 57 [1.4%] Asian, 527 [13.3%] Black, 740 [18.7%] Hispanic, 2,279 [57.7%] white, and 350 [8.9%] from other racial/ethnic groups [identified by parents as American Indian/Native American, Alaska Native, Native Hawaiian, Guamanian, Samoan, other Pacific Islander, or other race]). Distinct associations were observed between age, sex, and BMIz and whole amygdala volume, subregion volumes, and subregion apportionment. Pubertal stage was not related to amygdala subregion volumes. Age was associated with near-global expansion of amygdala subregions during this developmental period. Female sex was linked to smaller volumes in most amygdala subregions, with larger relative apportionment in dorsal amygdala subregions and smaller apportionment in the basolateral ventral paralaminar subregion. Higher BMIz was associated with smaller volumes in large laterobasal subregions, with increased relative apportionment in smaller subregions. This cross-sectional study suggests that age, but not pubertal stage, is associated with near-global expansion of the amygdala at ages 9 and 10, while sex and BMIz are linked to distinct changes in amygdala subregions that explain observed differences in total volumes. These findings provide a foundational context for understanding how developmental variables influence amygdala structure in preadolescents, with implications for understanding future risk for brain disorders.

Racial and Ethnic Disparities in Age-Specific All-Cause Mortality During the COVID-19 Pandemic

The end of the COVID-19 public health emergency (PHE) provides an opportunity to fully describe pandemic-associated racial and ethnic mortality disparities. Age-specific excess mortality differences have important downstream implications, especially in minoritized race and ethnicity populations. To characterize overall and age-specific all-cause excess mortality by race and ethnicity during the COVID-19 PHE and assess whether measured differences reflected changes from prepandemic disparities. This cross-sectional study analyzed data of all US residents and decedents during the COVID-19 PHE, aggregated by observed race and ethnicity (at time of death) and age. Statistical analysis was performed from March 2020 to May 2023. COVID-19 PHE period (March 2020 to May 2023). All-cause excess mortality (incident rates, observed-to-expected ratios) and all-cause mortality relative risks before and during the PHE. For the COVID-19 PHE period, data for 10 643 433 death certificates were available; mean (SD) decedent age was 72.7 (17.9) years; 944 318 (8.9%) were Hispanic; 78 973 (0.7%) were non-Hispanic American Indian or Alaska Native; 288 680 (2.7%) were non-Hispanic Asian, 1 374 228 (12.9%) were non-Hispanic Black or African American, 52 905 (0.5%) were non-Hispanic more than 1 race, 15 135 (0.1%) were non-Hispanic Native Hawaiian or Other Pacific Islander, and 7 877 996 (74.1%) were non-Hispanic White. More than 1.38 million all-cause excess deaths (observed-to-expected ratio, 1.15 [95% CI, 1.12-1.18]) occurred, corresponding to approximately 23 million years of potential life lost (YPLL) during the pandemic. For the total population (all ages), the racial and ethnic groups with the highest observed-to-expected all-cause mortality ratios were the American Indian or Alaska Native (1.34 [95% CI, 1.31-1.37]) and Hispanic (1.31 [95% CI, 1.27-1.34]) populations. However, higher ratios were observed in the US population aged 25 to 64 years (1.20 [95% CI, 1.18-1.22]), greatest among the American Indian or Alaska Native (1.45 [95% CI, 1.42-1.48]), Hispanic (1.40 [95% CI, 1.38-1.42]), and Native Hawaiian or Other Pacific Islander (1.39 [95% CI, 1.34-1.44]) groups. In the total population aged younger than 25 years, the Black population accounted for 51.1% of excess mortality, despite representing 13.8% of the population. Had the rate of excess mortality observed among the White population been observed among the total population, more than 252 000 (18.3%) fewer excess deaths and more than 5.2 million (22.3%) fewer YPLL would have occurred. In this cross-sectional study of the US population during the COVID-19 PHE, excess mortality occurred in all racial and ethnic groups, with disparities affecting several minoritized populations. The greatest relative increases occurred in populations aged 25 to 64 years. Documented differences deviated from prepandemic disparities.

Community-Level Social Vulnerability and Hip and Knee Joint Replacement Surgery Receipt Among Medicare Enrollees With Arthritis.

(1) Explore associations between county minority health social vulnerability index (MH-SVI) and total joint replacement (TJR), and (2) assess associations by individual-level race/ethnicity. An expanded understanding of relevant social determinants of health is essential to inform policies and practices that promote equitable access to hip and knee TJR. Retrospective cohort study of Medicare enrollees. Centers for Medicare and Medicaid Services claims data were linked with MH-SVI. Multivariable logistic regression models were used to evaluate the odds of TJR according to the MH-SVI quartile in which enrollees resided. A total of 10,471,413 traditional Medicare enrollees in 2018 aged 67 years or older with arthritis. The main outcome was enrollee primary TJR during hospitalization. The main exposure was the MH-SVI (composite and 6 themes) for the county of enrollee residence. Results were stratified by enrollee race/ethnicity. Asian American, Native Hawaiian, or Pacific Islander (AANHPI), Black or African American (Black), and Hispanic enrollees comparatively had 26%-41% lower odds of receiving TJR than White enrollees. Residing in counties within the highest quartile of composite and socioeconomic status vulnerability measures were associated with lower TJR overall and by race/ethnicity. Residing in counties with increased medical vulnerability for Black and White enrollees, housing type and transportation vulnerability for AANHPI and Hispanic enrollees, minority status and language theme for AANHPI enrollees, and household composition vulnerability for White enrollees were also associated with lower TJR. Higher levels of social vulnerability were associated with lower TJR. However, the association varied by individual race/ethnicity. Implementing multisectoral strategies is crucial for ensuring equitable access to care.
