Measuring refugees' capabilities: translation, adaptation, and valuation of the OxCAP-MH into Juba Arabic for use among South Sudanese male refugees in Uganda.

BACKGROUND: Forcibly displaced populations are highly vulnerable to psychosocial distress and mental disorders, including alcohol misuse. In an ongoing trial that seeks to develop a transdiagnostic intervention addressing psychological distress and alcohol use disorders among conflict-affected populations, we will carry out a cost-effectiveness evaluation using a capability-based Oxford Capabilities Mental Health (OxCAP-MH) measure. The OxCAP-MH is a 16-item questionnaire developed from the Capability Approach, that covers multiple domains of functioning and welfare. The aim of the current paper is to present the results of the translation, cultural adaptation and valuation of the OxCAP-MH into Juba Arabic for South Sudanese refugees living in Uganda. We adhered to the official Translation and Linguistic Validation process of the OxCAP-MH. To carry out the translation, the Concept Elaboration document, official English version of the OxCAP-MH, and the Back-Translation Review Template were used. Four independent translators were used for forward and back translations. The reconciled translated version was then piloted in two focus group discussions (N = 16) in Rhino refugee settlement. A most important to least important valuation of the sixteen capability domains covered in the OxCAP-MH was also done. RESULTS: The Juba Arabic version of the OxCAP-MH was finalized following a systematic iterative process. The content of the Juba Arabic version remained unchanged, but key concepts were adapted to ensure cultural acceptability, feasibility, and comprehension of the measure in the local context of Rhino refugee settlement. Most participants had low levels of literacy and required support with filling in the tool. Participants suggested an additional capability that is currently not reflected in the OxCAP-MH, namely access to food. Furthermore, discussions around the valuation exercise of the sixteen domains led to two separate importance scales, which showed relevant differences. CONCLUSIONS: In this context, the OxCAP-MH was considered culturally acceptable. The valuation exercise proved cognitively demanding. Participants voiced confusion over how to answer the questions on the OxCAP-MH instrument due to low levels of literacy. These concerns invite consideration for future research to consider how measures such as the OxCAP-MH can be made more accessible to individuals with low literacy rates in resource poor settings.

Firearm Ownership and Support for Political Violence in the United States.

Importance: Little is known about support for and willingness to engage in political violence in the United States. Such violence would likely involve firearms. Objective: To evaluate whether firearm owners' and nonowners' support for political violence differs and whether support among owners varies by type of firearms owned, recency of purchase, and frequency of carrying a loaded firearm in public. Design, Setting, and Participants: This cross-sectional nationally representative survey study was conducted from May 13 to June 2, 2022, among US adult members of the Ipsos KnowledgePanel, including an oversample of firearm owners. Exposure: Firearm ownership vs nonownership. Main Outcomes and Measures: Main outcomes concern (1) support for political violence, in general and to advance specific political objectives; (2) personal willingness to engage in political violence, by severity of violence and target population; and (3) perceived likelihood of firearm use in political violence. Outcomes are expressed as weighted proportions and adjusted prevalence differences, with P values adjusted for the false-discovery rate and reported as q values. Results: The analytic sample comprised 12 851 respondents: 5820 (45.3%) firearm owners, 6132 (47.7%) nonowners without firearms at home, and 899 (7.0%) nonowners with firearms at home. After weighting, 51.0% (95% CI, 49.9%-52.1%) were female, 8.5% (95% CI, 7.5%-9.5%) Hispanic, 9.1% (95% CI, 8.1%-10.2%) non-Hispanic Black, and 62.6% (95% CI, 61.5%-63.8%) non-Hispanic White; the mean (SD) age was 48.5 (18.0) years. Owners were more likely than nonowners without firearms at home to consider violence usually or always justified to advance at least 1 of 17 specific political objectives (owners: 38.8%; 95% CI, 37.3%-40.4%; nonowners: 29.8%; 95% CI, 28.5%-31.2%; adjusted difference, 6.5 percentage points; 95% CI, 4.5-9.3 percentage points; q < .001) but were not more willing to engage in political violence. Recent purchasers, owners who always or nearly always carry loaded firearms in public, and to a lesser extent, owners of assault-type rifles were more supportive of and willing to engage in political violence than other subgroups of firearm owners. Conclusions and Relevance: In this study of support for political violence in the United States, differences between firearm owners and nonowners without firearms at home were small to moderate when present. Differences were greater among subsets of owners than between owners and nonowners. These findings can guide risk-based prevention efforts.

Factors associated with the use of antibiotics for children presenting with illnesses with fever and cough obtained from prescription and non-prescription sources: a cross-sectional study of data for 37 sub-Saharan African countries.

INTRODUCTION: Fever and cough in under-five children are common and predominately self-limiting illnesses. Inappropriate prescribing of antibiotics in sub-Saharan Africa is a significant public health concern. However, prescription sources and use among children with fever or cough have not been explored. Therefore, we explored the factors associated with the use of antibiotics obtained from prescription and non-prescription sources for children with illnesses associated with fever and cough. METHODS: A secondary data analysis was conducted based on the Demographic and Health Survey (DHS) data from 37 sub-Saharan African countries. A total weighted sample of 18,866 under-five children who had a fever/cough and took antibiotics were considered for this study. Given the hierarchical nature of DHS data and the use of antibiotics prescribed from the formal healthcare setting (> 10%), a multilevel modified poisson regression model was fitted. Deviance was used for model comparison and the model with the lowest deviance value was chosen as the best-fitted model. Variables with p ≤ 0.2 in the bivariable analysis were considered for the multivariable modified poisson regression model. In the multivariable multilevel modified poisson regression model, the Adjusted Prevalence Odds Ratio (APOR) with a 95% Confidence Interval (CI) and p-value < 0.05 were reported to declare a significant association with taking antibiotics for fever/cough prescribed from formal healthcare setting. RESULTS: In sub-Saharan Africa, the proportion of use of antibiotics from informal healthcare setting for fever and cough among under-five children was 67.19% (95% CI: 66.51%, 67.85%). In the multilevel modified poisson regression analysis; residing in a rural area (APOR = 1.08, 95% CI: 1.04, 1.12), a child aged 36-47 months (APOR = 0.94, 95% CI: 0.90, 0.98), a child aged 48-59 months (APOR = 0.89, 95% CI: 0.84, 0.94), maternal primary education (APOR = 0.96, 95% CI: 0.93, 0.99), maternal secondary education (APOR = 0.95, 95% CI: 0.92, 0.99), belonged the middle household wealth status (APOR = 1.07, 95% CI: 1.02, 1.11), maternal exposure to news/electronic media (APR = 1.06, 95% CI: 1.02, 1.10), being from a household with 2 under-five children (APR = 0.94, 95% CI: 0.91, 0.97), being from a household with 3 under-five children (APR = 0.89, 95% CI: 0.85, 0.93), being from a household with 4 under-five children (APR = 0.90, 95% CI: 0.83, 0.98), and children of caregivers who were not involved in decision-making for their child health issues were significantly associated with taking antibiotics prescribed from formal healthcare setting for fever/cough among under-five children. CONCLUSION: Only two-thirds of the antibiotics used for children under five who had fever and cough were prescribed from formal healthcare setting. Our findings underscore the significance of addressing healthcare disparities, improving access to qualified healthcare providers, promoting maternal education, and empowering mothers in healthcare decision-making to ensure appropriate antibiotic use in this vulnerable population. Further research and interventions targeted at these factors are warranted to optimize antibiotic prescribing practices and promote responsible antibiotic use in the management of fever and cough in under-five children.

Secondary syphilis presenting with alopecia and leukoderma in a stable HIV-positive patient in a resource-limited setting: a case report.

BACKGROUND: Syphilis is an infection caused by the bacteria Treponema pallidum. It is mainly transmitted through oral, vaginal and anal sex, in pregnancy and through blood transfusion. Syphilis develops in primary, secondary, latent and tertiary stages and presents with different clinical features at each stage. Infected patients can remain asymptomatic for several years and, without treatment, can, in extreme cases, manifest as damage in several organs and tissues, including the brain, nervous tissue, eyes, ear and soft tissues. In countries with a high human immunodeficiency virus (HIV) burden, syphilis increases the risk of HIV infections. We report the case of a young HIV-positive black woman who presented with alopecia and hypopigmentation as features of secondary syphilis. CASE PRESENTATION: A virologically suppressed 29-year-old woman on Anti-retroviral Therapy (ART) presented with a short history of generalized hair loss associated with a non-itchy maculopapular rash and skin depigmentation on the feet. Limited laboratory testing confirmed a diagnosis of secondary syphilis. She was treated with Benzathine Penicillin 2.4MU. After receiving three doses of the recommended treatment, the presenting features cleared, and the patient recovered fully. CONCLUSION: This case demonstrates the importance of a high index of clinical suspicion and testing for syphilis in patients presenting with atypical clinical features of secondary syphilis, such as hair loss and hypopigmentation. It also highlights the challenges in diagnosing and clinically managing syphilis in a resource-limited setting.

Racial/ethnic differences in 21-gene recurrence score and survival among patients with estrogen receptor-positive breast cancer.

BACKGROUND: Despite numerous studies on racial/ethnic disparities among patients with breast cancer, there is a paucity of literature evaluating racial/ethnic differences in 21-gene recurrence score (RS) and survival differences stratified by RS risk categories. We thus performed an observational cohort study to examine racial/ethnic disparities in the context of RS. METHODS: The National Cancer Database (NCDB) was queried for female patients diagnosed between 2006 and 2018 with estrogen receptor (ER)-positive, pT1-3N0-1aM0 breast cancer who received surgery followed by adjuvant endocrine therapy and had RS data available. Logistic multivariable analysis (MVA) was built to evaluate variables associated with RS ≥ 26. Cox MVA was used to evaluate OS. Subgroup analyses were performed to compare the magnitude of racial/ethnic differences stratified by RS. P values less than 0.017 were considered statistically significant based on Bonferroni correction. RESULTS: A total of 140,133 women were included for analysis. Of these, 115,651 (82.5%), 8,213 (5.9%), 10,814 (7.7%), and 5,455 (3.9%) were NHW, Hispanic, Black, and API women, respectively. Median (IQR) follow up was 66.2 months (48.0-89.8). Logistic MVA showed that, compared with NHW women, Black women were associated with higher RS (≥ 26 vs < 26: adjusted odds ratio [aOR] 1.19, 95% confidence interval [CI] 1.12-1.26, p < 0.001), while HW (aOR 0.93, 95% CI 0.86-1.00, p = 0.04) and API women (aOR 1.03, 95% CI 0.95-1.13, p = 0.45) were not. Cox MVA showed that, compared with NHW women, Black women had worse OS (adjusted hazards ratio [aHR] 1.10, 95% CI 1.02-1.19, p = 0.012), while HW (aHR 0.85, 95% CI 0.77-0.94, p = 0.001) and API (aHR 0.66, 95% CI 0.56-0.77, p < 0.001) women had better OS. In subgroup analysis, similar findings were noted among those with RS < 26, while only API women were associated with improved OS among others with RS ≥ 26. CONCLUSION: To our knowledge, this is the largest study using nationwide oncology database to suggest that Black women were associated with higher RS, while HW and API women were not. It also suggested that Black women were associated with worse OS among those with RS < 26, while API women were associated with improved OS regardless of RS when compared to NHW women.

An ensemble penalized regression method for multi-ancestry polygenic risk prediction.

Great efforts are being made to develop advanced polygenic risk scores (PRS) to improve the prediction of complex traits and diseases. However, most existing PRS are primarily trained on European ancestry populations, limiting their transferability to non-European populations. In this article, we propose a novel method for generating multi-ancestry Polygenic Risk scOres based on enSemble of PEnalized Regression models (PROSPER). PROSPER integrates genome-wide association studies (GWAS) summary statistics from diverse populations to develop ancestry-specific PRS with improved predictive power for minority populations. The method uses a combination of L 1 (lasso) and L 2 (ridge) penalty functions, a parsimonious specification of the penalty parameters across populations, and an ensemble step to combine PRS generated across different penalty parameters. We evaluate the performance of PROSPER and other existing methods on large-scale simulated and real datasets, including those from 23andMe Inc., the Global Lipids Genetics Consortium, and All of Us. Results show that PROSPER can substantially improve multi-ancestry polygenic prediction compared to alternative methods across a wide variety of genetic architectures. In real data analyses, for example, PROSPER increased out-of-sample prediction R2 for continuous traits by an average of 70% compared to a state-of-the-art Bayesian method (PRS-CSx) in the African ancestry population. Further, PROSPER is computationally highly scalable for the analysis of large SNP contents and many diverse populations.

Perforated peptic ulcer - a case series and an African perspective.

BACKGROUND: Perforation of peptic ulcer (PPU) is the most morbid complication of peptic ulcer disease (PUD) with scant recent reports from sub-Saharan Africa. The aim of this study was to describe a PPU series from a single centre in South Africa and contrast the findings with other recent reports from sub-Saharan Africa. METHODS: A retrospective study of PPU at Kalafong Hospital in Pretoria was performed. The relationship of patient demographics, risk factors, ulcer pathology and severity scores to mortality were analysed. Recent similar reports from sub-Saharan Africa were reviewed and the findings compared to the current study and findings from high income countries (HIC). RESULTS: The study comprised 121 patients. The majority were black men with an average age of 46.6 years, with few comorbidities. A large proportion of patients admitted to risk factors and most presented to hospital 48 hours after the onset of symptoms. The majority (71%) of the perforations occurred in the stomach. The patient sex, age, risk factors and the mortality at 4% were similar to other African studies, although perforations were mainly duodenal in most of the African studies. The median age of patients in the East African studies was lower by 13 years. Patients in HIC series of PPU were older, more likely to be female, have duodenal perforations and a higher mortality than in the African series. CONCLUSION: Patients were mostly smokers, presented late to hospital and had gastric perforations. The findings of low mortality and male predominance concurred with those of other sub-Saharan African reports and were the opposite of trends in HIC.

"In our community, we normalize pain": discussions around menstruation and uterine fibroids with Black women and Latinas.

BACKGROUND: Uterine fibroids are non-cancerous neoplasms that arise from the uterus affecting over 75% of women. However, there is a disparity with Black women having an increased prevalence of nearly 80%. Black women also experience increased symptom burden, including younger age at the time of diagnosis and increased number and volume of fibroids. Less is known about other ethnoracially diverse women such as Latinas and the potential cultural impacts on fibroid burden and treatment. METHODS: Community engagement studios were conducted to facilitate discussions with stakeholders on their uterine fibroid and menstruation experience. We recruited Black women (n = 6) diagnosed with uterine fibroids and Latinas (n = 7) without uterine fibroids. We held two virtual community engagement studios split by uterine fibroid diagnosis. The studios were not audio recorded and notes were taken by four notetakers. The notes were thematically analyzed in Atlas.ti using content analysis. RESULTS: Participants felt there was a lack of discussion around menstruation overall, whether in the home or school settings. This lack of menstruation education was pronounced when participants had their first menstruation experience, with many unaware of what to expect. This silence around menstruation led to a normalization of painful menstruation symptoms. When it came to different treatment options for uterine fibroids, some women wanted to explore alternative treatments but were dismissed by their healthcare providers. Many participants advocated for having discussions with their healthcare provider about life goals to discuss different treatment options for their uterine fibroids. CONCLUSION: Despite uterine fibroid diagnosis, there is silence around menstruation. Menstruation is a normal biological occurrence and needs to be discussed to help prevent delayed diagnosis of uterine fibroids and possibly other gynecological disorders. Along with increased discussions around menstruation, further discussion is needed between healthcare providers and uterine fibroid patients to explore appropriate treatment options.

A Content Analysis of Online Messages about Sugar-Sweetened Beverages.

Media campaigns can reduce or promote the consumption of sugar-sweetened beverages (SSBs). Brief, US-based English-language online messages were gathered from searchable media platforms, a process that yielded 112 anti-SSB videos and 29 pro-SSB commercials. Using a combination of inductive and deductive methods, a content analysis of those messages was conducted to identify their properties. They were coded for the direction (pro vs. anti), target of the advocacy (e.g., consumption vs. policy), actor demographics (gender, age, and ethnicity), persuasive theme (e.g., excessive sugar, nurturing), and message sensation value. Anti-SSB appeals primarily targeted individual-level consumption behavior. They utilized six persuasive themes and often included more than one theme in a single message. Pro-SSB messages used feel-good themes and utilized only one theme per message. The proportions of adults, adolescents, and children differed by the direction of the advocacy. Black, Hispanic, and Asian actors were under-represented in the anti-SSB sample relative to Whites. Pro-SSB appeals were slightly higher than anti-SSB appeals in message sensation value (p = 0.09). The findings illuminate the message features that characterize the universe of brief anti-SSB appeals available online, highlight messaging disparities, and reveal the absence of certain common, effective persuasive themes.

Using Focus Groups to Explore Older Black Men's Perception of Dietary Interventions.

Older Black men are underrepresented in research despite being disproportionately affected by Alzheimer's disease (AD) and cardiovascular (CV) risk factors related to AD compared with non-Hispanic Whites. Although dietary interventions have shown promise to reduce modifiable CV risk factors related to AD, Black Americans have lower adherence likely due to lack of cultural considerations. Using a noninterventional convergent parallel mixed-methods approach, this study examined the cultural contexts that inform perceptions of dietary interventions among older Midwestern Black men. All participants completed an online demographic and dietary habit survey prior to focus group discussions. Two focus group discussion sessions were conducted with a total of 10 cognitively normal Black men aged 55 years and older. Survey data were analyzed using a frequency analysis and qualitative data were analyzed using a six-step thematic analysis process. Most men indicated having hypertension (N = 7, 77.8%) and currently not following a dietary eating pattern (N = 8, 88.9%). Emerging themes identified included (1) knowledge of dementia, (2) perceptions of dietary interventions, (3) barriers impacting participation in dietary interventions, and (4) overcoming barriers to engage Black men in dietary interventions. Findings from this study should inform the design of future dietary interventions for AD prevention to enhance participation among older Black men.

Exploring mental health problems and support needs among pregnant and parenting teenagers in rural areas Of Limpopo, South Africa.

BACKGROUND: Globally, teenage pregnancy is among the most social problems, affecting 21 million adolescents aged 15-19. Due to the increased responsibility of prenatal and postnatal care for their infants without support, pregnant and parenting teenagers, tend to experience mental health problems. Factors contributing to these problems among pregnant and parenting teenagers in rural African settings have hardly received scholarly attention and, therefore, are less understood. The purpose of the study was to explore mental health and challenges among pregnant and parenting teenagers,. METHOD(S): The study adopted a qualitative descriptive, exploratory, and phenomenological design. Purposive sampling was used to select 22 pregnant and parenting teenagers 18 years or older. Data were collected in ten selected clinics within the Demographic Surveillance Systems (HDSS) of DIMAMO and analysed using qualitative content analysis. RESULTS: The findings reveal that pregnant and parenting teenagers in rural areas experience various mental challenges such as depression. These challenges are caused by social problems such as stigmatisation, lack of support from families and friends, as well as parenting demands that contribute to poor progress at school or dropouts. Pregnant teens expressed concerns about the lack of spousal support resulting from abandoning their partners. CONCLUSIONS: Stress and depression were self-reported as mental problems among participants with various psychosocial implications, such as school dropout and miscarriage. There are various contributing factors to the mental health problems identified among pregnant and parenting teenagers, including inadequate family and spousal support. Access to integrated reproductive, psychosocial, and mental health services could be essential for these pregnant and parenting teenagers, to improve their mental well-being and improve the support system.

How inclusive were UK-based randomised controlled trials of COVID-19 vaccines? A systematic review investigating enrolment of Black adults and adult ethnic minorities.

OBJECTIVES: To establish if Black adults and adult ethnic minorities, defined as any group except White British, were represented in UK-based COVID-19 vaccination randomised controlled trials (RCTs) when compared to corresponding UK population proportions, based on 2011 census data. DESIGN: Systematic review of COVID-19 Randomised Controlled Vaccine Trials SETTING: United Kingdom PARTICIPANTS: Randomised Controlled Trials of COVID-19 vaccines conducted in the UK were systematically reviewed following PRISMA guidelines. MeSH terms included "Covid-19 vaccine", "Ad26COVS1", and "BNT162 Vaccine" with keywords such as [covishield OR coronavac OR Vaxzevria OR NVX-CoV2373] also used. Studies that provided (A) participant demographics and (B) full eligibility criteria were included. The following key data was extracted for analysis: number of participants analysed, number of Black adults and number of adult minority ethnicity participants. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome is the mean percentage of Black adults randomised to COVID-19 vaccine trials deemed eligible within this review. The secondary outcome is the mean percentage of adult ethnic minorities randomised. RESULTS: The final review included 7 papers and a total of 87 sets of data collated from trial sites across the UK. The standard mean percentage of Black adults included in the trials (0.59%, 95% CI: 0.13% - 1.05%) was significantly lower compared to the recorded Black adult population (2.67%) indicating that they were under-served in UK based COVID-19 vaccine RCTs (p < 0.001). Adult ethnic minority presence (8.94%, 95% CI: 2.07% - 15.80%) was also lower than census data (16.30%), indicating they were also under-served (p = 0.039). CONCLUSION: The findings show that COVID-19 vaccine trials failed to adequately randomise proportionate numbers of Black adults and adult minority ethnicities. More inclusive practices must be developed and implemented in the recruitment of underserved groups to understand the true impact of COVID-19.

Protocol of the study: Multilevel community-based mental health intervention to address structural inequities and adverse disparate consequences of COVID-19 pandemic on Latinx Immigrants and African refugees.

The NIMH-funded Multilevel Community-Based Mental Health Intervention to Address Structural Inequities and Adverse Disparate Consequences of COVID-19 Pandemic on Latinx Immigrants and African Refugees study aims to advance the science of multilevel interventions to reduce the disparate, adverse mental health, behavioral, and socioeconomic consequences of the COVID-19 pandemic that are a result of complex interactions between underlying structural inequities and barriers to health care. The study tests three nested levels of intervention: 1) an efficacious 4-month advocacy and mutual learning model (Refugee and Immigrant Well-being Project, RIWP); 2) engagement with community-based organizations (CBOs); and 3) structural policy changes enacted in response to the pandemic. This community-based participatory research (CBPR) study builds on long-standing collaboration with five CBOs. By including 240 Latinx immigrants and 60 African refugees recruited from CBO partners who are randomly assigned to treatment-as-usual CBO involvement or the RIWP intervention and a comparison group comprised of a random sample of 300 Latinx immigrants, this mixed methods longitudinal waitlist control group design study with seven time points over 36 months tests the effectiveness of the RIWP intervention and engagement with CBOs to reduce psychological distress, daily stressors, and economic precarity and increase protective factors (social support, access to resources, English proficiency, cultural connectedness). The study also tests the ability of the RIWP intervention and engagement with CBOs to increase access to the direct benefits of structural interventions. This paper reports on the theoretical basis, design, qualitative and quantitative analysis plan, and power for the study.

Multi-trait GWAS for diverse ancestries: mapping the knowledge gap.

BACKGROUND: Approximately 95% of samples analyzed in univariate genome-wide association studies (GWAS) are of European ancestry. This bias toward European ancestry populations in association screening also exists for other analyses and methods that are often developed and tested on European ancestry only. However, existing data in non-European populations, which are often of modest sample size, could benefit from innovative approaches as recently illustrated in the context of polygenic risk scores. METHODS: Here, we extend and assess the potential limitations and gains of our multi-trait GWAS pipeline, JASS (Joint Analysis of Summary Statistics), for the analysis of non-European ancestries. To this end, we conducted the joint GWAS of 19 hematological traits and glycemic traits across five ancestries (European (EUR), admixed American (AMR), African (AFR), East Asian (EAS), and South-East Asian (SAS)). RESULTS: We detected 367 new genome-wide significant associations in non-European populations (15 in Admixed American (AMR), 72 in African (AFR) and 280 in East Asian (EAS)). New associations detected represent 5%, 17% and 13% of associations in the AFR, AMR and EAS populations, respectively. Overall, multi-trait testing increases the replication of European associated loci in non-European ancestry by 15%. Pleiotropic effects were highly similar at significant loci across ancestries (e.g. the mean correlation between multi-trait genetic effects of EUR and EAS ancestries was 0.88). For hematological traits, strong discrepancies in multi-trait genetic effects are tied to known evolutionary divergences: the ARKC1 loci, which is adaptive to overcome p.vivax induced malaria. CONCLUSIONS: Multi-trait GWAS can be a valuable tool to narrow the genetic knowledge gap between European and non-European populations.

Antiracism and positive intergenerational (infant) outcomes: A county-level examination of low birth weight and infant mortality.

Racism is associated with negative intergenerational (infant) outcomes. That is, racism, both perceived and structural, is linked to critical, immediate, and long-term health factors such as low birth weight and infant mortality. Antiracism-resistance to racism such as support for the Black Lives Matter (BLM) movement-has been linked to positive emotional, subjective, and mental health outcomes among adults and adolescents. To theoretically build on and integrate such past findings, the present research asked whether such advantageous health correlations might extend intergenerationally to infant outcomes? It examined a theoretical/correlational process model in which mental and physical health indicators might be indirectly related to associations between antiracism and infant health outcomes. Analyses assessed county-level data that measured BLM support (indexed as volume of BLM marches) and infant outcomes from 2014 to 2020. As predicted, in the tested model, BLM support was negatively correlated with 1) low birth weight (Ncounties = 1,445) and 2) mortalities (Ncounties = 409) among African American infants. Given salient, intergroup, policy debates tied to antiracism, the present research also examined associations among White Americans. In the tested model, BLM marches were not meaningfully related to rates of low birth weight among White American infants (Ncounties = 2,930). However, BLM support was negatively related to mortalities among White American infants (Ncounties = 862). Analyses controlled for structural indicators of income inequality, implicit/explicit bias, voting behavior, prior low birth weight/infant mortality rates, and demographic characteristics. Theory/applied implications of antiracism being linked to nonnegative and positive infant health associations tied to both marginalized and dominant social groups are discussed.

Type 2 Diabetes Mellitus and Helicobacter pylori Eradication in a Clinical Population.

OBJECTIVES: Eradication of Helicobacter pylori reduces the risk of gastric cancer (GC). Individuals with type 2 diabetes mellitus (T2DM) are known to be at increased risk for GC. In a cohort of H. pylori-positive individuals, we assessed whether those with T2DM were at risk of persistent infection following H. pylori treatment compared with individuals without T2DM. METHODS: A random subset of all individuals diagnosed as having H. pylori without intestinal metaplasia at endoscopy from 2015 to 2019 were stratified evenly by race (Black and White). After excluding those with T1DM and those without eradication testing after H. pylori treatment, logistic regression analysis was used to determine the association of T2DM with the risk of persistent H. pylori infection following treatment. RESULTS: In 138 patients, H. pylori eradication rates did not differ between the 27% of individuals with T2DM compared to those without (81.1% vs 81.2%). After adjusting for age, race, and insurance status, we found no significant increased risk of persistent H. pylori infection for individuals with T2DM (odds ratio 1.40; 95% confidence interval 0.49-3.99). CONCLUSIONS: H. pylori eradication rates do not differ by T2DM status, providing support for clinical trials of H. pylori eradication to reduce GC incidence among high-risk populations in the United States, such as individuals with T2DM.

Geographical accessibility to functional emergency obstetric care facilities in urban Nigeria using closer-to-reality travel time estimates: a population-based spatial analysis.

BACKGROUND: Better accessibility for emergency obstetric care facilities can substantially reduce maternal and perinatal deaths. However, pregnant women and girls living in urban settings face additional complex challenges travelling to facilities. We aimed to assess the geographical accessibility of the three nearest functional public and private comprehensive emergency obstetric care facilities in the 15 largest Nigerian cities via a novel approach that uses closer-to-reality travel time estimates than traditional model-based approaches. METHODS: In this population-based spatial analysis, we mapped city boundaries, verified and geocoded functional comprehensive emergency obstetric care facilities, and mapped the population distribution for girls and women aged 15-49 years (ie, of childbearing age). We used the Google Maps Platform's internal Directions Application Programming Interface to derive driving times to public and private facilities. Median travel time and the percentage of women aged 15-49 years able to reach care were summarised for eight traffic scenarios (peak and non-peak hours on weekdays and weekends) by city and within city under different travel time thresholds (≤15 min, ≤30 min, ≤60 min). FINDINGS: As of 2022, there were 11·5 million girls and women aged 15-49 years living in the 15 studied cities, and we identified the location and functionality of 2020 comprehensive emergency obstetric care facilities. City-level median travel time to the nearest comprehensive emergency obstetric care facility ranged from 18 min in Maiduguri to 46 min in Kaduna. Median travel time varied by location within a city. The between-ward IQR of median travel time to the nearest public comprehensive emergency obstetric care varied from the narrowest in Maiduguri (10 min) to the widest in Benin City (41 min). Informal settlements and peripheral areas tended to be worse off compared to the inner city. The percentages of girls and women aged 15-49 years within 60 min of their nearest public comprehensive emergency obstetric care ranged from 83% in Aba to 100% in Maiduguri, while the percentage within 30 min ranged from 33% in Aba to over 95% in Ilorin and Maiduguri. During peak traffic times, the median number of public comprehensive emergency obstetric care facilities reachable by women aged 15-49 years under 30 min was zero in eight (53%) of 15 cities. INTERPRETATION: Better access to comprehensive emergency obstetric care is needed in Nigerian cities and solutions need to be tailored to context. The innovative approach used in this study provides more context-specific, finer, and policy-relevant evidence to support targeted efforts aimed at improving comprehensive emergency obstetric care geographical accessibility in urban Africa.

Celebrating organizational history triggers social identity threat among Black Americans.

Many mainstream organizations celebrate their historical successes. In their history, however, they often marginalized racial minorities, women, and other underrepresented groups. We suggest that when organizations celebrate their histories, even without mentioning historical marginalization, they can undermine belonging and intentions to join the organization among historically marginalized groups. Four experiments demonstrate that Black participants who were exposed to an organization that celebrated their history versus the present showed reduced belonging and intentions to participate in the organization. These effects were mediated by expectations of biased treatment in the organization. Further, when organizations had a history of Black people in power, celebrating history was no longer threatening, highlighting that the negative effects of celebrating history are most likely when organizations are or are assumed to be majority-White and have treated Black Americans poorly. Taken together, these findings suggest that emphasizing organizational history can be a source of social identity threat among Black Americans.

Demographic bias in misdiagnosis by computational pathology models.

Despite increasing numbers of regulatory approvals, deep learning-based computational pathology systems often overlook the impact of demographic factors on performance, potentially leading to biases. This concern is all the more important as computational pathology has leveraged large public datasets that underrepresent certain demographic groups. Using publicly available data from The Cancer Genome Atlas and the EBRAINS brain tumor atlas, as well as internal patient data, we show that whole-slide image classification models display marked performance disparities across different demographic groups when used to subtype breast and lung carcinomas and to predict IDH1 mutations in gliomas. For example, when using common modeling approaches, we observed performance gaps (in area under the receiver operating characteristic curve) between white and Black patients of 3.0% for breast cancer subtyping, 10.9% for lung cancer subtyping and 16.0% for IDH1 mutation prediction in gliomas. We found that richer feature representations obtained from self-supervised vision foundation models reduce performance variations between groups. These representations provide improvements upon weaker models even when those weaker models are combined with state-of-the-art bias mitigation strategies and modeling choices. Nevertheless, self-supervised vision foundation models do not fully eliminate these discrepancies, highlighting the continuing need for bias mitigation efforts in computational pathology. Finally, we demonstrate that our results extend to other demographic factors beyond patient race. Given these findings, we encourage regulatory and policy agencies to integrate demographic-stratified evaluation into their assessment guidelines.

Psychobiography in sociocultural context: the application of culture-based theories of psychology on a culturally diverse historic subject pool.

In recent years the historical subject base in psychobiography has expanded from a traditional focus on White (Caucasian) subjects to a broader more culturally inclusive population of significant personalities throughout history. A critical component of strong multicultural psychobiography is the inclusion of anchoring theories of psychology that are rooted in socio-cultural-political context. To psychologically profile culturally diverse individuals with only traditional Western theories of psychology and psychiatry (e.g. medical models, psychodynamic, existential, cognitive-behavioral) limits the ability of the research to accurately capture the erlebnis (lived experience) of extraordinary individuals in proper cultural context. This article reviews specific psychological theories that have recently set a foundation for more nuanced and culturally contextualised psychological profiles of historic personalities who represent diverse racial/ethnic/cultural backgrounds. Among the theories covered are the Integrated African Psychology Perspective (IAPP), an Indigenous (Native American) model of psychobiography, as well as theories and models on Psychological Nigrescence (Black racial identity development), Intersectionality, Politicised Collective Identity (PCI), Queered Black Racial Identity Development (QBRID), and Adultification of Black Children, among others. Examples of applications of these culture-centered theories to psychobiography, drawn from the present authors recently completed psychobiographies, as well as from other researchers internationally, are presented.
