"The Nurse Told Her to Get Checked More Regularly Because She is Having Sex with Black Men": An Exploration of the Sexual Health Experiences of Black Heterosexual Men in London.

Drivers of poor sexual health outcomes among Black heterosexual man are poorly understood. Previous research has identified a need to understand Black men's behavioral experiences and motivators in the UK. This study aimed to address this gap through a phenomenological exploration of the sexual health experiences and motivators of Black heterosexual men with experience of higher-risk sexual behaviors living in London. Semi-structured interviews were conducted with 10 participants (18-58 years) recruited through barbershops. Reflexive thematic analysis was used to analyze the data. Five themes were generated. For relevance, three themes are discussed in this paper: 1) The Black Man's Battle; 2) Sexual Socialization; and 3) Sexual Behaviors, Relationships, and Health. Race and gender combined to shape experience of sexual socialization. Exposure to explicit media content from a young age promoted multiple sexual partners. Racist sexual stereotypes exposed participants to fetishization and created pressure to meet sexual expectations. Condom use motivators were complex and multifaceted. Experience of institutional racism created a lack of trust in services. However, actual experiences with sexual health services were positive and counteracted the mistrust created by racism. Sexual health services should better tailor their work to Black heterosexual men and diversify their offer. Services should collaborate with Black community organizations to deliver services outside clinical settings.

The Impact of Undermining Coparenting on the Mental and Physical Health Outcomes of Black Fathers: The Role of Depression and Restrictive Emotionality

ABSTRACT The parenting literature has established the coparenting relationship as central to the parenting behaviors and outcomes of men. The construct of coparenting encompasses supportive efforts among individuals that facilitate the rearing of children and unsupportive actions that can undermine parenting efforts (Merrifield & Gamble, 2013). Few studies have examined undermining coparenting as an experience that shapes Black men’s health outcomes. In this study, we apply the social determinants of health framework to examine the impact of Black fathers’ perceptions of undermining coparenting on their self-reported ratings of mental and physical health. Using a nationally representative sample of Black men (n = 255), correlational analyses revealed perceptions of undermining coparenting to be a significant predictor of higher levels of anger and poorer perceptions of physical health. These relationships were found to be mediated by depressive symptoms and moderated by restrictive emotionality. It is recommended that the negative impact of undermining coparenting on health be considered as a potential comorbidity contributing to negative health outcomes for Black men. This study adds to the literature on coparenting, Black men’s health, and Black fatherhood more generally and urges policymakers and practitioners to consider undermining as an often overlooked, but significant, social determinant of health impacting the well-being of Black men. We also offer recommendations for promoting Black men’s health by educating families on the effects of undermining and offering the supports necessary for achieving positive coparenting dynamics.

Comparing barriers to early stage diagnosis of hepatocellular carcinoma between safety net hospitals and academic medical centers: An analysis from the United States Safety-Net Collaborative.

Early detection of hepatocellular carcinoma (HCC) is associated with improved survival. However, a greater proportion of patients treated at safety net hospitals (SNHs) present with late-stage disease compared to those at academic medical centers (AMCs). This study aims to identify barriers to diagnosis of HCC, highlighting differences between SNHs and AMCs. The US Safety Net Collaborative-HCC database was queried. Patients were stratified by facility of diagnosis (SNH or AMC). Patient demographics and HCC screening rates were examined. The primary outcome was stage at diagnosis (AJCC I/II-"early"; AJCC III/IV-"late"). 1290 patients were included; 50.2% diagnosed at SNHs and 49.8% at AMCs. At SNHs, 44.4% of patients were diagnosed late, compared to 27.6% at AMCs. On multivariable regression, Black race was associated with late diagnosis in both facilities (SNH: odds ratio 1.96, p = 0.03; AMC: 2.27, <0.01). Screening was associated with decreased odds of late diagnosis (SNH: 0.46, p = 0.04; AMC: 0.37, p < 0.01). Black race was associated with late diagnosis of HCC, while screening was associated with early diagnosis across institutional types. These results suggest socially constructed racial bias in screening and diagnosis of HCC. Screening efforts targeting SNH patients and Black patients at all facilities are essential to reduce disparities.

Disparities in Access to Timely Waitlisting Among Pediatric Kidney Transplant Candidates.

Kidney transplantation with minimal or no dialysis exposure provides optimal outcomes for children with end-stage kidney disease. We sought to understand disparities in timely access to transplant waitlisting. We conducted a retrospective, registry-based cohort study of candidates ages 3 to 17 added to the US kidney transplant waitlist 2015 to 2019. We defined "preemptive waitlisting" as waitlist addition before receiving dialysis and compared demographics of candidates based on preemptive status. We used competing risk regression to determine the association between preemptive waitlisting and transplantation. We then identified waitlist additions age >18 who initiated dialysis as children, thereby missing pediatric allocation prioritization, and evaluated the association between waitlisting with pediatric prioritization and transplantation. Among 4506 pediatric candidates, 48% were waitlisted preemptively. Female sex, Hispanic ethnicity, Black race, and public insurance were associated with lower adjusted relative risk of preemptive waitlisting. Preemptive listing was not associated with time from waitlist activation to transplantation (adjusted hazard ratio 0.94, 95% confidence interval 0.87-1.02). Among transplant recipients waitlisted preemptively, 68% had no pretransplant dialysis, whereas recipients listed nonpreemptively had median 1.6 years of dialysis at transplant. Among 415 candidates initiating dialysis as children but waitlisted as adults, transplant rate was lower versus nonpreemptive pediatric candidates after waitlist activation (adjusted hazard ratio 0.54, 95% confidence interval 0.44-0.66). Disparities in timely waitlisting are associated with differences in pretransplant dialysis exposure despite no difference in time to transplant after waitlist activation. Young adults who experience delays may miss pediatric prioritization, highlighting an area for policy intervention.

Community and Commerce

“‘Where Do We Go from Here?’: Histories of Long-term Black Business Ownership, Community, and Family in Los Angeles County” is an oral history project of African American business owners conducted by the UCLA Center for Oral History Research. This report describes the design and implementation of the project, the challenges of outreach, and the ways in which narrators participated and negotiated their own agendas and investments in the project. It also argues for the importance of business oral history as a means of documenting African American community and social history. As this project shows, business oral histories can record the daily particulars of small business’s operations and the challenges business owners face, offer insight into the legacy of African American multi-generational businesses, demonstrate the on-going impact of racism and segregation on Black-owned businesses, and give evidence of how Black business owners conceive their relationship and responsibilities to the African American community.

Evaluation of the Golden Proportion, Golden Percentage, and Recurring Esthetic Dental Proportion in Kenyans of African Descent.

To evaluate the validity of the Golden Proportion, Golden Percentage, and Recurring Esthetic Dental (RED) Proportion among Kenyans of African descent with naturally well-aligned teeth. Standardized frontal photographic images of the smiles of 175 participants aged 18-35 years were obtained, and Adobe Photoshop was used to analyze and measure the frontal widths of the maxillary central and lateral incisorsand canines in triplicate. The average teeth widths were calculated to determine the existence of the Golden Proportion, Golden Percentage, and RED Proportion, and their validity using independent sample t-tests to compare the differences in the mean teeth widths at α < 0.05. The number of male and female participants was 107 (61.1%) and 68 (38.9%), respectively. The Golden Proportion between the maxillary central and lateral incisors was found in 4.0% on the right and 2.8% on the left of all the participants, but between the maxillary lateral incisors and canines was found in only 0.6% on the right of male participants (p < 0.0001). The RED Proportion between the maxillary lateral and central incisors was in the range of 67%-70%, and between the canines and lateral incisors was 82%-84% (p < 0.0001). The proportion of RED was not constant, and gradually increased distally. The Golden Percentage of 15% was observed in the lateral incisors bilaterally; however, in the central incisors and the canines, the Golden Percentage was 22% and 12%, respectively. The Golden and RED Proportions were invalid determinants of anterior teeth proportions. The Golden Percentage existed only in the lateral incisors. The Golden Proportion, RED Proportion, and Golden Percentage theories may not be applicable to all populations when designing smiles. Racial and ethnic backgrounds are important considerations to establish objective quantifiable values of anterior tooth proportions that are beneficial for esthetic restorations.

Impact of opioid overdoses on US life expectancy and years of life lost, by demographic group and stimulant co-involvement: a mortality data analysis from 2019 to 2022

The United States' opioid crisis is worsening, with the number of deaths reaching 81,806 in 2022 after more than tripling over the past decade. This study aimed to comprehensively characterize changes in burden of opioid overdose mortality in terms of life expectancy reduction and years of life lost between 2019 and 2022, including differential burden across demographic groups and the contribution of polysubstance use. Using life tables and counts for all-cause and opioid overdose deaths from the National Center for Health Statistics, we constructed cause-eliminated life tables to estimate mortality by age in the absence of opioid-related deaths. We calculated the loss in life expectancy at birth (LLE) and total years of life lost (YLL) due to opioid overdose deaths by state of residency, sex, racial/ethnic group, and co-involvement of cocaine and psychostimulants. Opioid-related deaths in the US led to an estimated 3.1 million years of life lost in 2022 (38 years per death), compared to 2.0 million years lost in 2019. Relative to a scenario with no opioid mortality, we estimate that opioid-related deaths reduced life expectancy nationally by 0.67 years in 2022 vs 0.52 years in 2019. This LLE worsened in all racial/ethnic groups during the study period: 0.76y-0.96y for white men, 0.36y-0.55y for white women, 0.59y-1.1y for Black men, 0.27y-0.53y for Black women, 0.31y-0.82y for Hispanic men, 0.19y-0.31y for Hispanic women, 0.62y-1.5y for American Indian/Alaska Native (AI/AN) men, 0.43y-1y for AI/AN women, 0.09y-0.2y for Asian men, and 0.08y-0.13y for Asian women. Nearly all states experienced an increase in years of life lost (YLL) per capita from 2019 to 2022, with YLL more than doubling in 16 states. Cocaine or psychostimulants with abuse potential (incl. methamphetamines) were involved in half of all deaths and years of life lost in 2022, with substantial variation in the predominant drug class by state and racial/ethnic group. The burden of opioid-related mortality increased dramatically in the US between 2019 and 2022, coinciding with the period of the COVID-19 pandemic and the associated disruptions to social, economic, and health systems. Opioid overdose deaths are an important contributor to decreasing US life expectancy, and Black, Hispanic, and Native Americans now experience mortality burdens approaching or exceeding white Americans.

A survey study of Alzheimer’s stigma among Black adults: intersectionality of Black identity and biomarker diagnosis

ABSTRACT Objective We urgently need to understand Alzheimer’s disease (AD) stigma among Black adults. Black communities bear a disproportionate burden of AD, and recent advances in early diagnosis using AD biomarkers may affect stigma associated with AD. The goal of our study is to characterize AD stigma within our cohort of self-identified Black participants and test how AD biomarker test results may affect this stigma. Design We surveyed a sample of 1,150 self-identified Black adults who were randomized to read a vignette describing a fictional person, who was described as either having a positive or negative biomarker test result. After reading the vignette, participants completed the modified Family Stigma in Alzheimer’s Disease Scale (FS-ADS). We compared FS-ADS scores between groups defined by age, gender, and United States Census region. We examined interactions between these groupings and AD biomarker test result. Results Participants over age 65 had lower scores (lower stigma) on all 7 FS-ADS domains compared to those under 65: structural discrimination, negative severity attributions, negative aesthetic attributions, antipathy, support, pity, and social distance. In the biomarker positive condition, worries about structural discrimination were greater than in the biomarker negative condition and statistically similar in the two age groups (DOR, 0.39 [95%CI, 0.22–0.69]). This pattern of results was similar for negative symptom attributions (DOR, 0.51 [95%CI, 0.28–0.90]). Conclusion While older adults reported less AD stigma than younger adults, AD biomarker testing caused similarly high concerns about structural discrimination and negative severity attributions. Thus, use of AD biomarker diagnosis may increase AD stigma and exacerbate healthcare disparities known to effect AD diagnosis in some Black adults. Advances in AD diagnosis may interact with social and structural factors to differentially affect groups of Black adults.

The Influence of Race on Detected and Undetected Sexual Offense Histories: A Comparison of White and Black Men Committed as Sexually Violent Persons.

Understanding the difference between the proportion of sexual offenses that are officially detected versus the total number of sexual crimes that occur has been of interest to decision makers for some time. Previous studies have not considered possible racial differences. More aggressive responses by police and the criminal justice system as well as cultural differences in victim type/reporting rates may result in differences between detection rates of Black versus White men. In the current study (N = 190), we examined the difference between Black (n = 51) and White (n = 139) men committed to a forensic hospital as a Sexually Violent Person on factors that could impact the detected rate. Overall, we found that White men had significantly more total victims, undetected victims, undetected and detected child victims, total male victims, undetected male victims, undetected acquaintance victims, and total (detected and undetected) acquaintance victims than Black men. Black men had significantly more detected adult victims, but this difference did not remain when accounting for undetected victims. We explore reasons for these differences as well as provide recommendations for practice.

Characterization and prevalence of ocular comorbidities and risk of legal blindness across the United States.

Vision loss is a top disability in the United States (US). Patients commonly present with multiple ocular diseases, but the extent to which this places them at risk for vision loss, and if sex and race impacts this, is poorly understood. This exploratory analysis evaluated which ocular comorbidities and demographics are at highest risk for visual impairment. A retrospective cross-sectional study was conducted through the TriNetX Analytics Network, an aggregated network encompassing over 90 million insured and uninsured patients across 50 healthcare organizations from all regions in the US. Patients with diabetic retinopathy (DR), age-related macular degeneration (AMD), retinal vein occlusion (RVO), glaucoma, and uveitis were included in this study. Ocular diseases and visual impairment were determined through ICD-10 codes. Prevalence and odds ratios were calculated while stratifying by sex and racial demographics. Statistical analyses were completed using RStudio and Excel with 95% confidence intervals calculated. The comorbid conditions with the highest prevalence of visual impairment were uveitis and RVO (39.94%), uveitis and neovascular AMD (37.61%), and uveitis and glaucoma (33.23%). The comorbidity with the highest odds for visual impairment was uveitis and RVO (POR 4.86; 95% CI 4.49, 5.26). Compared to white males, Black and Hispanic males were disproportionately affected by visual impairment across ocular comorbidities. This study quantified the prevalence and odds of visual impairment for unilateral and comorbid ocular disease, with the addition of uveitis causing the greatest increase. Black and Hispanic males were disproportionately affected by visual impairment across comorbid conditions.

Sociodemographic Factors Correlate with Late Stage Pediatric Hodgkin Lymphoma and Rhabdomyosarcoma: A Report from the Children's Oncology Group Registries.

We examined association between late stage diagnosis and individual- and community-level characteristics among pediatric Hodgkin lymphoma (HL) and rhabdomyosarcoma (RMS) patients. We obtained Children's Oncology Group (COG) data from 1999-2021 including summary stage (local (L), regional (R), distant (D)), tumor subtype, demographics, and ZIP code at diagnosis. We linked ZIP codes to county-level redlining scores (C,D=greatest redlining), Child Opportunity Index (COI), and measures of segregation (racial dissimilarity indices (DI)). Logistic regressions calculated odds ratios for late stage diagnosis, and by race within tumor subtype. 5,933 HL and 2,800 RMS patients were included. Late stage diagnosis of HL was correlated with Black race (ORDistant(D) vs regional/local(R&L)=1.38 [1.13-1.68]), being uninsured (ORD vs R&L=1.38 [1.09-1.75]), and subtype (Nodular sclerosis vs Other HL: ORD vs R&L=1.64 [1.34-2.01], Untyped: ORD vs R&L=1.30 [1.04-1.63]). Late stage rhabdomyosarcoma was correlated with bilingual households (ORDistant/regional(D&R) vs local(L)=2.66 [1.03-6.91]) and tumor type (Alveolar vs Embryonal ORD vs R&L=6.16 [5.00-7.58]. Community-level factors associated with late stage HL were greater Black (OR80-100%=1.83; 95% CI=1.11-3.02) and Hispanic (OR60-79%=1.30; 95%CI=1.05-1.60) DI. Late stage diagnosis for RMS was associated with more redlined census tracts within counties (OR=1.54; 95% CI =1.02-2.35) and low/very low COI (OR=1.21; 95% CI=1.02-1.45). Novel markers of community deprivation, such as redlining and racial segregation, likely affect cancer outcomes for children with HL and RMS in this first disparities study using COG registries. The interplay of multilevel risk factors provides important consideration for efforts to improve early detection of pediatric cancer diagnosis.

Surprise Billing Is Common in Total Joint Arthroplasty and Negatively Impacts Patient Satisfaction.

Patients undergoing total joint arthroplasty (TJA) may receive unexpected medical bills. Such "surprise" bills may cause financial hardship for patients, which prompted policymakers to pass the No Surprises Act. The purpose of this study was to determine the incidence of surprise bills for patients undergoing TJA and the effect of surprise billing on patient satisfaction. This was a retrospective study of patients who underwent a primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) at a large multi-state institution. Patients completed a questionnaire regarding the incidence of surprise bills after their surgery, details of those bills, and how the bills affected their surgical satisfaction. Independent predictors for receiving a surprise bill were assessed through a multivariate regression analysis. Twelve percent of participants received at least one surprise bill after their TJA. The most common surprise bill came from the surgical facility (48%), followed by anesthesia (36%). Multivariate logistic regression analysis identified older age and Black race to be independent predictors of surprise billing. Furthermore, surgery occurring after the No Surprises Act bill enforcement on January 1, 2022, was found to increase a patient's likelihood of receiving a surprise bill (P=.039, effect size=0.18). Patients who received a surprise bill reported being significantly less satisfied with their surgery (P=.002, effect size=0.45). Forty-nine percent of patients with a surprise bill felt their billing negatively affected their surgical satisfaction. Surprise billing continues to occur after TJA and can negatively affect patient satisfaction. Although surgeons may be unable to limit the amount of bills patients receive postoperatively, increased communication and education regarding the perioperative billing process may prove to be beneficial for both patient satisfaction and the physician-patient relationship.

Factors affecting advance care planning in older adults with cancer

IntroductionAdvance care planning (ACP) has been widely endorsed and recommended for its many potential benefits, including improved end-of-life (EOL) care, enhanced satisfaction with care, and reduced anxiety and depression. However, little is known about the ACP completion rates and factors affecting ACP among older adults with cancer. This study's purpose was to examine biological, psychological, and social factors affecting ACP in this population. Materials and MethodsData from the 2002 to 2016 waves of exit interviews from the national longitudinal Health and Retirement Study were analyzed. The sample included 1088 decedents, aged 55 and over, who had a diagnosis of cancer. The exit interviews were completed by a proxy respondent (usually the next of kin of the decedents). ACP outcomes included: having EOL care discussion, durable power of attorney (DPOA), and advance directives (ADs). Multiple logistic regression models were conducted to examine the relationships between predictor variables and each of the three ACP outcome variables. ResultsApproximately 65% of the sample had ever discussed EOL care, 61.9% had an assigned DPOA, and 54.1% had ADs. Regression results showed that higher age, Black race, high school and above education, being widowed/never married, higher multimorbidity, and more limitations in activities of daily living and instrumental activities of daily living were significantly associated with the three ACP variables. Surprisingly, Black race was associated with higher odds of ever discussing EOL care and having ADs; high school and above education was associated with lower odds of all three ACP components. DiscussionThe majority of participants in this study had discussed EOL care, had an assigned DPOA, and had ADs. However, most participants were White/Caucasian and had completed high school education. Future research that includes more diverse and minoritized participants is needed. Also, the contrasting association of Black race and higher educational status with ACP outcomes warrant further exploration in future studies.

Rethink Recovery: A Qualitative Approach to Exploring Messaging for Medication-Assisted Recovery (MAR).

Similar to national trends, in Illinois, fatal opioid overdoses have risen. Black men (35+) outrank all other racial subgroups for the highest rate of fatal opioid overdoses in the state. To address this, Prevention First and the Illinois Department of Human Services developed a public health education campaign to support increasing enrollment in recovery services, with a focus on Black men (35+). Self-reported Black participants with opioid use disorder (OUD) made up the analytic sample. Study goals were to understand lived experiences of the campaign audience; investigate knowledge, attitudes, and beliefs regarding OUD and treatment; explore perceived barriers and facilitators to treatment; and evaluate messaging that showcased medication-assisted recovery (MAR) as a viable tool for treatment and recovery. Interviews were recorded and transcribed for thematic analysis. Participants shared long and cyclical journeys of use and recovery. Participants had low levels of knowledge of available treatment options and struggled to imagine themselves in recovery because of the fear of cravings and withdrawal. Messaging that was realistic about the cyclical nature of recovery, showed the varying options for MAR, and addressed cravings and withdrawals were well received. These findings illustrate the importance of understanding an audience and involving them in campaign development to create messaging that promotes behavior change and sustained health. Through the Decision Blocks strategic framework, we discovered information gaps, barriers to treatment, and practical solutions to increase access to treatment for Black men with OUD that has been limited due to inequities caused by structural racism.

Feasibility and Acceptability of a Prospective Syphilis Sexual Network Study for Sexual Minority Men.

In preparation for a prospective syphilis network study of sexual minority men, we conducted a mixed-methods formative study with the following objectives: a) assess acceptability of respondent driven sampling (RDS), b) assess acceptability of study procedures, c) social network seed selection, and d) pilot an ecological momentary assessment (EMA) study to assess social networking, sexual and substance use behavior. We conducted in-depth interviews with eight providers serving sexual minority men and five focus group discussions with 34 sexual minority men, prioritizing four target populations: young Black sexual minority men, 2) on PrEP, 3) living with HIV, 4) not engaged in care. The 4-week EMA pilot was conducted with 40 sexual minority men. EMA survey responses were analyzed to evaluate how different compensation levels influenced response rates. Brief exit surveys were used to assess EMA app acceptability. Primary themes identified through qualitative data collection: 1) importance of developing trust and maintaining confidentiality during proposed recruitment activities, 2) importance of compensating participants appropriately for study activities, and 3) cultural considerations for increasing visibility and participation of young Black sexual minority men. All EMA participants reported being "completely comfortable" reporting sexual behavior through the app. Most (78%) preferred the app to in-person interviews. Several participants identified technical issues with the app, including not receiving push notifications and spontaneous closure. This mixed-methods formative study allowed for adjustments to and tailoring of the planned network study, including recruitment protocols, compensation type and amount, and EMA survey wording and response items.

Fatal and Nonfatal Firearm Injury Rates by Race and Ethnicity in the United States, 2019 to 2020.

Racial disparities in firearm injury death in the United States are well established. Less is known about the magnitude of nonfatal and total firearm injury. To combine health care data with death certificate data to estimate total firearm injuries in various racial and ethnic groups. Retrospective, cross-sectional study. Fatal injury data were collected from the Centers for Disease Control and Prevention. Data on nonfatal injuries were collected from the Nationwide Emergency Department Sample (NEDS), a 20% stratified sample of U.S. emergency department visits, weighted to provide national estimates for the United States, 2019 to 2020. All firearm injuries and deaths in the United States. Race and ethnicity were classified into 5 mutually exclusive categories: Asian or Pacific Islander, Black, Hispanic, Native American, and White. International Classification of Diseases, 10th Revision codes were used to classify firearm injury intent. Incidence of fatal and nonfatal injury in the U.S. population and case-fatality ratios (CFRs). There were 252 376 total firearm injuries, including 84 908 deaths from firearm injures. Of all firearm injuries, 37.8% were unintentional, 37.3% were assault related, 21.0% were self-harm, and 1.3% were law enforcement associated. Self-harm had the highest CFRs (90.9% overall). Unintentional injuries accounted for just 1021 (1.2%) deaths but 94 433 (56.4%) of nonfatal injuries. Rates of self-harm were highest among White persons (11.0 per 100 000 population in 2020) followed by Native Americans (8.6 per 100 000). Rates of assault were highest among Black persons (70.1 per 100 000), as were unintentional injuries (56.1 per 100 000). Findings are limited by the accuracy of discharge coding in NEDS, particularly regarding injury intent and patient race and ethnicity. From 2019 to 2020, the total burden of firearm injuries amounts to an average of 1 injury every 4 minutes and 1 death every 12 minutes in the United States. Racial disparities in firearm injury death are mirrored in nonfatal injury. None.

An Empirical Analysis of Avoidable Medicare Payments and Medicare Payment Variations

This study investigates the determinants of average Medicare payments, focusing on the impact of secondary diagnoses, demographic factors, and regional disparities. Our model reveals that major complications and comorbidities (MCCs) significantly increase average Medicare payments compared to less severe complications (CCs), with coefficients of 7674.13 and 1542.67, respectively. Higher percentages of the elderly living in poverty correlate with increased payments, highlighting the influence of social determinants on healthcare costs. Demographic analysis shows that counties with higher populations of Black, Hispanic, Asian, or other races receive higher Medicare payments, indicating potential racial disparities in healthcare access and quality. Political affiliation also plays a role, with Democrat-voting counties incurring higher Medicare costs. Surprisingly, larger populations served correlate with decreased payments, possibly due to cost-containment programs like Medicare’s Competitive Bidding. State-level analysis reveals significant regional variations, with states like Oregon and Wyoming showing higher payments, while Mississippi and Georgia have the lowest. Our findings underscore the complexity of Medicare funding and the need for targeted policy interventions to address health disparities and ensure sustainable healthcare delivery.

Impact of Prostate-Specific Antigen Screening Pattern on Prostate Cancer Mortality Among Non-Hispanic Black and Non-Hispanic White Men: A Large, Urban Health System Cohort Analysis.

Randomized studies assessing the effect of PSA screening on mortality in non-Hispanic Black (NHB) men are lacking. We aimed to assess the association between PSA screening and survival among NHB men in comparison to non-Hispanic White (NHW) men in a racially diverse real-world North American population. The study cohort included 6378 men who self-identified as NHB or NHW and were diagnosed with prostate cancer (PCa). Patients received PSA screening and subsequent PCa treatment and follow-up at our institution. Patients were sorted based on PSA testing intensity for the 5 years prior to diagnosis, as follows: never, some (<1 test/y), and annual testing (1 test/y). The primary outcome was risk of prostate cancer-specific mortality (PCSM). Competing risk cumulative incidence curves estimated PCSM rates. Competing risk regression analyses examined the impact of PSA testing on PCSM. An interaction term was incorporated to assess the impact of race on the outcome. Median (IQR) age and PSA at diagnosis were 67 (60-73) years and 5.8 (4.4-9.6) ng/mL, respectively, and 2929 (46%) men were NHB (Kruskal-Wallis P values < .001). Annual PSA testing was more frequent in NHW (5%) than in NHB (3%) men (χ2 P value < .001). On cumulative incidence analysis, in the never, some, and annual PSA testing groups, the 10-year PCSM was respectively 12.3%, 5.8%, and 4.6% in NHW and 18.5%, 7%, and 1.2% in NHB patients (Gray's test P values < .001). At CCR, PSA screening rate was associated with more favorable PCSM rates (HR: 0.47; 95% CI 0.33-0.68; P < .001). The interaction term for race did not show statistical significance (P = .2). PSA testing was associated with a reduced risk of PCSM in both NHB and NHW men diagnosed with PCa. Additionally, the positive impact of the screening rate seemed to be independent of race.

Genetic predictors of blood pressure traits are associated with preeclampsia

Preeclampsia, a pregnancy complication characterized by hypertension after 20 gestational weeks, is a major cause of maternal and neonatal morbidity and mortality. Mechanisms leading to preeclampsia are unclear; however, there is evidence of high heritability. We evaluated the association of polygenic scores (PGS) for blood pressure traits and preeclampsia to assess whether there is shared genetic architecture. Non-Hispanic Black and White reproductive age females with pregnancy indications and genotypes were obtained from Vanderbilt University’s BioVU, Electronic Medical Records and Genomics network, and Penn Medicine Biobank. Preeclampsia was defined by ICD codes. Summary statistics for diastolic blood pressure (DBP), systolic blood pressure (SBP), and pulse pressure (PP) PGS were acquired from Giri et al. Associations between preeclampsia and each PGS were evaluated separately by race and data source before subsequent meta-analysis. Ten-fold cross validation was used for prediction modeling. In 3504 Black and 5009 White included individuals, the rate of preeclampsia was 15.49%. In cross-ancestry meta-analysis, all PGSs were associated with preeclampsia (ORDBP = 1.10, 95% CI 1.02–1.17, p = 7.68 × 10−3; ORSBP = 1.16, 95% CI 1.09–1.23, p = 2.23 × 10−6; ORPP = 1.14, 95% CI 1.07–1.27, p = 9.86 × 10−5). Addition of PGSs to clinical prediction models did not improve predictive performance. Genetic factors contributing to blood pressure regulation in the general population also predispose to preeclampsia.

2D:4D digit ratio as a potential marker for prostate cancer risk

BackgroundThe second-to-fourth digit ratio (2D:4D) is thought to reflect prenatal exposure to sex steroids. We investigated the relationship between 2D:4D and odds of prostate cancer. MethodData were collected in PROtEuS, a population-based case-control study conducted in Montréal, Canada (2005–2012), including 1931 incident prostate cancer cases aged < 76 years and 1994 population controls. In-person interviews elicited information on potential risk factors. Digit lengths were measured by interviewers applying a standard protocol. Odds ratios (OR) and 95 % confidence intervals (CI) were estimated using unconditional logistic regression adjusting for potential confounders. ResultsThe OR of prostate cancer for a standard deviation increase in 2D:4D was 0.91 (95 % CI: 0.85–0.98). For less and more aggressive cancers, ORs were 0.93 (95 % CI: 0.87–1.00) and 0.85 (95 % CI: 0.77–0.93), respectively. There was an interaction with ancestry (p=0.04), whereas the OR among men of African descent was 1.23 (95 % CI: 0.96–1.57, based on 128 cases). ConclusionFindings suggest an inverse association between 2D:4D and odds of overall prostate cancer, more pronounced for aggressive cancers. This supports the notion that high levels of testosterone in utero, estimated by a low 2D:4D ratio, are associated with a higher risk of prostate cancer. Contrastingly, a high digit ratio was associated with greater cancer odds among participants of African descent. Upon replication, 2D:4D could prove to be an easily measured marker of prostate cancer risk.
