RESUMO

The apolipoprotein-E4 (APOE*4) and apolipoprotein-E2 (APOE*2) alleles are more common in African American versus non-Hispanic white populations, but relationships of both alleles with Alzheimer's disease (AD) pathology among African American individuals are unclear. We measured APOE allele and ß-amyloid (Aß) and tau using blood samples and positron emission tomography (PET) images, respectively. Individual regression models tested associations of each APOE allele with Aß or tau PET overall, stratified by racialized group, and with a racialized group interaction. We included 358 older adults (42% African American) with Aß PET, 134 (29% African American) of whom had tau PET. APOE*4 was associated with higher Aß in non-Hispanic white (P < 0.0001), but not African American (P = 0.64) participants; racialized group modified the association between APOE*4 and Aß (P < 0.0001). There were no other racialized group differences. These results suggest that the association of APOE*4 and Aß differs between African American and non-Hispanic white populations. Other drivers of AD pathology in African American populations should be identified as potential therapeutic targets.

RESUMO

BACKGROUND: Comprehensive sex and sexuality education (CSE) is an evidence-based intervention associated with improved sexual and reproductive health outcomes. Currently, there are no standardized requirements for sex and sexuality education in the United States, despite expert recommendations. CONTRIBUTIONS TO THEORY: In the United States, a Whole School, Whole Community, Whole Child theoretical model proposed by the Centers for Disease Control, and current examples of school sex education policy is used to make recommendations for the standardization of comprehensive sexual health education in K-12 schools. This article describes the necessary components to adopt CSE equitably, and provides an example of the process implemented to improve CSE in 1 school district in Pittsburgh, PA. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Understanding the key components of legislation that align with recommended standards, and the process of advocating for school policy change, allows local advocacy groups and education policymakers to create and pass feasible legislation that will ensure appropriate instruction. There is additional room for improvement in states and local districts that have current CSE legislation, to adopt approaches grounded in frameworks that critically evaluate social determinants of health and amend legislation to further improve health equity. CONCLUSIONS: Several states and local districts have passed CSE regulations, and are implementing and evaluating their efficacy, providing support and examples for other regions interested in adopting similar policies and processes. Pittsburgh Public Schools can be used as an example adapting current legislation and adopting more comprehensive language.

RESUMO

BACKGROUND: In singleton pregnancies, fetal sexual dimorphism has been observed in hypertensive disorders of pregnancy, particularly preeclampsia, a morbid syndrome that increases the risk of adult-onset cardiovascular disease for mothers and their offspring. However, few studies have explored the effect of fetal sex on hypertensive disorders of pregnancy among twin pregnancies. METHODS: We conducted a retrospective cohort study of 1032 twin pregnancies between 2011 and 2022 using data from a perinatal database that recruits participants from 3 hospitals in Houston, TX. We categorized pregnancies based on fetal sex pairings into female/female, male/male, and female/male. Pregnancies with female/female pairs were used as our reference group. Our primary outcomes included gestational hypertension, preeclampsia, superimposed preeclampsia, and preeclampsia subtyped by gestational age of delivery. A modified Poisson regression model with robust error variance was used to calculate the relative risk and 95% CI for the association between fetal sex pairs and hypertensive disorders of pregnancy. RESULTS: Adjusted models of female/male pairs were associated with preterm preeclampsia (relative risk, 2.01 [95% CI, 1.15-3.53]) relative to those with female/female pairs. No associations with other hypertensive disorders of pregnancy were observed among pregnancies with male/male pairs compared with those with female/female fetal sex pairs. CONCLUSIONS: We found some evidence of sexual dimorphism for preterm preeclampsia among female/male twin pairs. Additional research is needed to understand what biological mechanisms could explain these findings.

RESUMO

Objective: To document pregnancy and birthing experiences of young, Black pregnant women in one geographic area to make recommendations for improving young Black women's pregnancy and birthing experiences. Methods: Participants were recruited through The YoungMoms Study (R01 DA04640101A1) in Pittsburgh, Pennsylvania, and included Black or biracial participants ages 16-23 (n = 25). Individual interviews were conducted from March 2022-July 2022 to assess pre-, peri-, and post-natal healthcare system encounters; experiences of structural and obstetric racism and discrimination in healthcare settings while obtaining prenatal care; attitudes around healthcare systems and medical professionals; effects of COVID-19 pandemic on participants lives and the impact of enacted healthcare policies in their perinatal experience; substance use changes during pregnancy; and coping mechanisms for stress. NVivo 13 was used to code transcripts, then major themes and subthemes were identified using thematic content analysis and based on grounded theory. Results: Twenty-five interviews were conducted, and four themes emerged from participant experiences of racial discrimination in healthcare settings; (1) awareness of historical racism that influences perinatal care; (2) clinical providers assume participant substance use and enact reproductive coercion; (3) clinical providers question validity of Black women's birthing complaint; and (4) Young Black pregnant women know and will express what they desire in their perinatal experience if asked. Conclusions: Young Black pregnant women encounter structural racism and intersectional bias from healthcare providers. By centering the perspectives and experiences of this overlooked population, public health researchers and clinical providers can utilize anti-racist frameworks to create more equitable, just practices in reproductive healthcare.

RESUMO

Background: In singleton pregnancies, fetal sexual dimorphism has been observed in hypertensive disorders of pregnancy (HDP), particularly preeclampsia, a morbid syndrome that increases risk of adult onset cardiovascular disease for mothers and their offspring. However, few studies have explored the effect of fetal sex on HDP among twin pregnancies. Methods: We conducted a retrospective cohort study of 1,032 twin pregnancies between 2011 - 2022 using data from a perinatal database that recruits participants from three hospitals in Houston, TX. We categorized pregnancies based on fetal sex pairings into female/female, male/male, and female/male. Pregnancies with a female/female fetal sex were used as our reference group. Our primary outcomes included gestational hypertension, preeclampsia, superimposed preeclampsia, and preeclampsia subtyped by gestational age of delivery. A modified Poisson regression model with robust error variance was used to calculate the relative risk (RR) and 95% confidence interval (CI) for the association between fetal sex pairs and HDP. Results: Adjusted models of female/male fetal sex pairs were associated with preterm preeclampsia (RR 2.01, 95% CI 1.15-3.53) relative to those with female/female fetuses. No associations with other HDP were observed among pregnancies with male/male fetal sex compared to those with female/female fetal sex pairs. Conclusions: We found some evidence of sexual dimorphism for preterm preeclampsia among female/male twin pairs. Additional research is needed to understand what biological mechanisms could explain these findings.

RESUMO

BACKGROUND: The novel coronavirus 2019 (COVID-19) pandemic exacerbated existing health inequities in the United States, but no studies have focused on the lived experiences of younger Black birthing people. The goal of this qualitative study was to center the experiences of younger pregnant and birthing Black and Biracial people during the pandemic. METHODS: We recruited 25 Black and Biracial pregnant and birthing people ages 16-23 for individual semi-structured interviews. Participants were asked about experiences with the healthcare system during the pandemic, and interviews were transcribed verbatim and coded for qualitative analysis using nVivo. We adhered to the Consolidated Criteria for Reporting Qualitative Research guidelines. RESULTS: Participants identified pandemic-related stressors such as fears about infection, lack of support, and pressure to get vaccinated. Reasons for vaccine hesitancy included mistrust in the government and racism experienced during reproductive healthcare. Provider appeals highlighting patient autonomy and science were more effective in encouraging vaccine uptake than emotional appeals that made participants feel guilty about potentially infecting loved ones. CONCLUSIONS: Restrictions on children and support people created barriers to timely prenatal care and reduced tangible support for young Black and Biracial birthing people during the pandemic. Their vaccine hesitancy was related to mistrust, concerns that the vaccines had not been tested enough prior to roll-out, and possible side effects of the vaccine including infection with the virus and pregnancy loss. Obstetric providers need to understand and recognize the ongoing impact of obstetric and scientific racism on health communication with younger Black and Biracial patients.

RESUMO

OBJECTIVE: The objective of this study was to qualitatively examine coping mechanisms and desired supports in pregnant and birthing Black and Biracial adolescent and young adult women during the COVID-19 pandemic. METHODS: Black and Biracial participants ages 16-23 were recruited for virtual individual semi-structured interviews. Participants (n = 25) were asked about pre- and post-natal experiences with the healthcare system, effects of the pandemic, and participants' experiences of or desires for ideal care within the healthcare system. Interviews were transcribed verbatim and coded for qualitative analysis using nVivo. Discussions around postpartum mental health evolved organically when asked about how participants were coping postpartum. RESULTS: Nearly half the interviewees organically reported mental health symptoms consistent with postpartum depression (PPD) during questions regarding their postpartum experience. Of the 11 interviewees who reported mental health symptoms consistent with PPD, 2 were afraid to disclose their symptoms to a healthcare provider due to fear of child protective services involvement and their belief they would be treated unfairly because of their race. CONCLUSION: Clinicians who care for Black and Biracial adolescent and young adult mothers must be particularly attuned to structural barriers for appropriate screening and treatment of postpartum depression. Expanding investigations of intersectional influences on young mothers' perinatal health and PPD are needed.

RESUMO

Introduction: Efforts to address vaccine uptake and access among black adults will be relevant for continued coronavirus disease 2019 (COVID-19) eradication efforts and can be transferable to other prevention efforts in future pandemics. This study investigated factors related to COVID-19 vaccine uptake and access among black residents in Allegheny County, PA. Methods: Surveys were administered electronically from October 2021 to January 2022 to black Allegheny County residents aged 18 and older. Questions included thoughts on COVID mitigation strategies (e.g., masking, social distancing), vaccination status, intention to vaccinate children, trust of COVID-19 information sources and vaccines, family needs, access to support services, and social media use to access information. Descriptive statistics and significant correlates of being vaccinated using adjusted logistic regression models are reported. Results: Of the overall sample (N=397), the majority were fully vaccinated (n=306, 77%). Fully vaccinated participants were more likely to be female (62.5%, p=0.010), age 60 years or older (34.3%, p=0.0002), have some college education (23.2%, p<0.0001), and be employed full time (50.0%, p=0.0001) compared with nonvaccinated individuals. Among the unvaccinated participants (n=91), the primary reason was fear of illness (8.9%), long-term effects (6.5%), mistrust in the vaccine (6.3%), and needing more information (4.5%). Vaccine-hesitant participants were more likely to be unvaccinated (adjusted odds ratio=2.3, 95% confidence interval 1.25-4.14) after adjusting for age, education, employment, insurance, health status, and income. Conclusion: Vaccine hesitancy may be improved by directly addressing fear of illness resulting from vaccines and improving clarity in the vaccine development and approval process to improve uptake among black adults.

RESUMO

BACKGROUND: Substance use among adolescent girls is associated with numerous risk characteristics, including engaging in sexual risk behaviors, which can lead to HIV and sexually transmitted infection (STI) diagnoses. This is an important phenomenon to target as there is a significant race-gendered paradox that occurs when Black girls use and misuse drugs. When misuse occurs among this group, they are more likely to face harsher consequences and worse health outcomes than boys and other ethnic-minority girls. Therefore, there is a need to understand the risk and protective factors of drug use and sexual risk behaviors among Black girls and develop a robust intervention that can cater for this group. OBJECTIVE: We propose the development of a strengths-based prevention education intervention for Black girls between the ages of 13 and 18 years to promote protective factors. METHODS: A sequential, mixed methods study will be conducted, and we will use the first 3 steps of the ADAPT-ITT (assessment, decision, adaptation, production, topical experts, integration, training, testing) framework to begin the development of the intervention. Three aims will be described in this protocol. First, aim 1 is to explore sociocultural risk and protective factors among Black girls between the ages 13 and 18 years in drug use and HIV/STI prevention using focus group methodology and surveys. We will conduct at least 10 focus groups to include up to 75 Black girls or until we reach saturation. Our target sample size for the quantitative portion of the study will be 200 participants. Aim 2 will focus on deciding upon an intervention based on findings from aim 1 and forming a youth advisory board to guide intervention development. Aim 3 will be to conduct a pretest of the intervention with the youth advisory board to determine if the intervention is feasible and will be accepted by Black girls. RESULTS: The study is part of a 2-year research pilot study award from the National Institutes of Mental Health. Data collection for this study began in October 2021. For aim 1, data collection is 95% complete. We expect to complete all data collection for aim 1 on or before May 30, 2023. Study activities for aim 2 are occurring simultaneously as data are being collected and analyzed and will be completed in the summer of 2023. Study activities for aim 3 will begin in the fall of 2023. CONCLUSIONS: This study will be one of the few interventions that address both sexual health and drug use together and cater to Black girls. We anticipate that the intervention will be beneficial for Black girls across the nation to work on building culturally appropriate prevention education and building peer social supports, resulting in reduction or delayed substance use and improved sexual health.

RESUMO

To explore the association between acculturation among foreign-born (FB) women, gestational diabetes (GDM) and GDM-associated adverse birth outcomes, we conducted a retrospective cohort study of 34,696 singleton pregnancies from Houston, TX, between 2011 and 2022. FB women (n = 18,472) were categorized based on years of residence in US (0-5, 6-10, and > 10 years), while US-born women (n = 16,224) were the reference group. A modified Poisson regression model determined the association between acculturative level and GDM within the entire cohort and stratified by race/ethnicity. Compared to US-born women, FB women with 0-5 years [adjusted relative risk (RRadj.) 1.27, 95% confidence interval [CI] 1.14-1.42)], 6-10 years (RRadj. 1.89, 95%CI 1.68-2.11) and > 10 years in the US (RRadj. 1.85, 95%CI 1.69-2.03) had higher risk of GDM. Results were consistent for all racial/ethnic groups, although associations were not significant at 0-5 years. FB women had lower risk of other adverse pregnancy outcomes, except for preeclampsia with severe features at higher levels of acculturation. Results were similar among those with and without GDM. In conclusion, FB status increases risk of GDM among all racial/ethnic groups but is elevated with higher acculturation levels.

RESUMO

Although Black girls use substances at lower rates than boys and girls from various other racial groups, they tend to have worse health outcomes associated with substance use that can also impact their sexual health. The association between substance use and sexual risk behaviors is usually attributed to lack of access to quality health care and lack of culturally specific prevention programming and treatment options tailored to this group. Accordingly, the theoretical frameworks for health promotion for Black girls often focus on addressing deficits, ignoring the powerful and intersecting social forces that can impact identity, agency, and behavioral options. Key among these forces is gendered racism. We propose a strengths-based conceptual framework to address and challenge gendered racism as a critical foundation for promoting health and wellbeing for Black girls. Our approach integrates Intersectionality Theory and Empowerment Theory, with psychological and intrapersonal empowerment identified as critical mediators of behavior and health outcomes, supported by protective factors of positive racial identity and gendered racial socialization. This framework has been developed with and for Black girls but can be adapted for health promotion efforts with other minoritized groups.

RESUMO

Compared to youth a decade ago, today's youth experience increased rates of mental health concerns as well as greater severity of mental health issues. Prior to the COVID-19 pandemic in 2020, over a third of youth reported feeling sad and hopeless and one in five reported having seriously considered suicide. With this grim reality, schools and communities are no longer able to ignore how mental health affects the daily lives, social and emotional development, and identify formation of their youth. When schools implement mental health promotion programs and policies, they not only promote academic success but also increase protective factors that establish an environment supportive of help-seeking behaviors. Active Minds is committed to improving mental health outcomes for youth, specifically LGBTQIA2S+ students, enrolled in K-12 schools across the United States. These recommendations, grounded in evidence-based best practices, provide support for schools as they work to improve student mental health. These recommendations include the following:Implementing the Whole School, Whole Child, Whole Community (WSCC) model;Centering youth voices in mental health promotion;Participating in surveillance efforts;Ensuring mental health support for students with diverse identities and needs;Providing space to address individual biases and stigma;Developing and aligning policies and culture to support youth mental health.

RESUMO

OBJECTIVE: Preterm birth (any birth at less than 37 weeks of gestation) disproportionally affects Black birthing people and is associated with adverse perinatal and fetal health outcomes. Racism increases the risk of preterm birth, but standardized measurement metrics are elusive. This narrative synthesis examines literature on measures of racial discrimination used in preterm birth research. DATA SOURCES: Six databases (CINAHL, Cochrane, EMBASE, PubMed [MEDLINE], Scopus, Web of Science) and ClinicalTrials.gov were searched. Search terms were categorized into three groups (racism terms, measurement terms, preterm birth terms) to identify original research articles that explored associations between racism and preterm birth. English-language, original research articles with U.S. populations were included. METHODS OF STUDY SELECTION: Studies were excluded if conducted in only White populations, if only paternal factors were included, or if only racial differences in preterm birth were described. Articles were independently reviewed by two blinded researchers for inclusion at every stage of screening and data extraction; a third reviewer resolved discrepancies. TABULATION, INTEGRATION, AND RESULTS: Sixty studies were included in the final analysis. Articles primarily included measures examining interpersonal forms of racism (n=17) through the Experiences of Discrimination and Everyday Discrimination scales, neighborhood composition (n=22) with the Neighborhood Deprivation Index and the Index of Concentration at the Extremes, policy-level racism (n=12) through institutions such as residential racial segregation or policy inequities, or multiple forms (n=9). CONCLUSION: Among studies, assessment methods and application of constructs varied. This heterogeneity poses significant challenges to understanding associations between racial discrimination and preterm birth and to describing potential etiologic pathways of preterm birth, which ultimately hinders development of effective intervention. Strategies to capture multilevel exposures to racism require the development and expansion of metrics that are culturally inclusive, empirically valid, and reliable among Black pregnant populations.

RESUMO

While Black girls have lower rates of drug use, they face worse health and wellbeing consequences associated with drug use. Understanding which strengths-based factors serve as buffers to limit adverse outcomes related to drug use among Black girls is essential for prevention. This study investigated the mediating role of sociopolitical control on drug use among Black girls (n = 340). Using path analysis, models were tested to include the variables of interest. Sociopolitical control (e.g. leadership competency and policy control) significantly mediated the relationship between ethnic identity and social support on drug use. Implications from this study may consider bolstering empowerment-based strategies in drug use prevention for Black girls.

RESUMO

Fetal-sex-specific changes to placental immunity and metabolism occur in response to obesity. Few studies have determined if fetal sex interacts with maternal characteristics to alter risk of gestational diabetes mellitus (GDM). Among 43,727 singleton pregnancies, we examined the association between male fetal sex and GDM using log-binomial logistic regression to calculate relative risks (RR) and 95% confidence intervals (CI). Interactions were examined between fetal sex and maternal characteristics on the risk of GDM by calculating relative excess risk due to interaction. After adjusting for body mass index, race/ethnicity, maternal age, education, and gravidity, male fetal sex was not associated with GDM (RRadj. 0.95, 95% CI 0.93, 1.04). We found a positive interaction between male fetal sex and obesity (p = 0.04). Nonobese women with male fetuses were less likely to develop GDM, but in the presence of obesity, an opposite trend was observed. There was a positive interaction between male fetal sex and GDM on the risk of preterm delivery < 37-weeks gestation (p = 0.0006). In response to underlying maternal obesity, fetal sex may modify the risk of GDM. In addition, male fetal sex may increase the occurrence of preterm birth among women with GDM.

RESUMO

Scrofuloderma is an uncommon cutaneous presentation of tuberculosis. It can be difficult to diagnose, as it can mimic various skin conditions, including hidradenitis suppurativa. We report a case of a 46-year-old female refugee patient with a history of nodules and sinus tracts in the left axilla treated for many years as hidradenitis suppurativa in her home country who was later found to have scrofuloderma. The diagnosis was based on a positive Mycobacterium tuberculosis polymerase chain reaction from an ultrasound-guided aspiration. Further investigation excluded pulmonary tuberculosis. In cases with an atypical presentation of hidradenitis suppurativa, imaging, along with histological and microbiologic examination are warranted to exclude scrofuloderma.

RESUMO

Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Here, using whole-genome, exome and transcriptome sequencing of 2,754 childhood patients with ALL, we find that, despite a generally low mutation burden, ALL cases harbor a median of four putative somatic driver alterations per sample, with 376 putative driver genes identified varying in prevalence across ALL subtypes. Most samples harbor at least one rare gene alteration, including 70 putative cancer driver genes associated with ubiquitination, SUMOylation, noncoding transcripts and other functions. In hyperdiploid B-ALL, chromosomal gains are acquired early and synchronously before ultraviolet-induced mutation. By contrast, ultraviolet-induced mutations precede chromosomal gains in B-ALL cases with intrachromosomal amplification of chromosome 21. We also demonstrate the prognostic significance of genetic alterations within subtypes. Intriguingly, DUX4- and KMT2A-rearranged subtypes separate into CEBPA/FLT3- or NFATC4-expressing subgroups with potential clinical implications. Together, these results deepen understanding of the ALL genomic landscape and associated outcomes.

RESUMO

Hypertensive disorders of pregnancy (HDP) result in maternal morbidity and mortality but are rarely examined in perinatal studies of sexually transmitted infections. We examined associations between common sexually transmitted infections and HDP among 38,026 singleton pregnancies. Log-binomial regression calculated relative risk (RRs) and 95% confidence intervals (CIs) for associations with gestational hypertension, preeclampsia with severe features, mild preeclampsia, and superimposed preeclampsia. All models were adjusted for insurance type, maternal age, race/ethnicity, and education. Additional adjustments resulted in similar effect estimates. Chlamydia was associated with preeclampsia with severe features (RRadj. 1.4, 95% CI 1.1, 1.9). Effect estimates differed when we examined first prenatal visit diagnosis only (RRadj. 1.3, 95% CI 0.9, 1.9) and persistent or recurrent infection (RRadj. 2.0, 95% CI 1.1, 3.4). For chlamydia (RRadj. 2.0, 95% CI 1.3, 2.9) and gonorrhea (RRadj. 3.0, 95% CI 1.1, 12.2), women without a documented treatment were more likely to have preeclampsia with severe features. Among a diverse perinatal population, sexually transmitted infections may be associated with preeclampsia with severe features. With the striking increasing rates of sexually transmitted infections, there is a need to revisit the burden in pregnant women and determine if there is a link between infections and hypertensive disorders of pregnancy.

RESUMO

Coaching Boys into Men (CBIM), an evidence-based violence prevention program, utilizes the coach-athlete relationship to deliver information about healthy, respectful relationships to adolescent boys involved in athletics. Although CBIM has demonstrated effectiveness in clinical research trials, its implementation outside of an effectiveness study has not been explored. The purpose of this current study was to explore facilitators and barriers of effective implementation in community settings using experiences from one regional implementation in Southwestern Pennsylvania. Head coaches who implemented CBIM from 2017-2018 seasons (n = 35) were contacted and 22 (63%) agreed to participate. Coaches were asked how they delivered CBIM to their team, what aided the process, barriers to facilitation, and their overall thoughts on CBIM implementation. Interviews were structured to uncover specific information regarding implementation while also providing time and space for coaches to voice their suggestions and opinions. Interviews were coded using descriptive content analysis. Key facilitators to implementation were involvement of violence prevention advocates, athletic directors, assistant coaches, and players and having flexibility to integrate current events to emphasize topics covered in CBIM. Observed improvements in bystander intervention behaviors and better attitudes towards women and girls among athletes were key motivators for coaches to continue the program. Main barriers were inconsistencies in time available to discuss topics with players and need to refresh curriculum content over multiple seasons. Coaches identified components necessary for broader and sustained implementation of this evidence-based violence prevention intervention in community settings. Coaches' confidence in delivering program content can be bolstered with appropriate strategies in place to address barriers. As coaches witness positive impacts among their athletes, these successes contribute to coaches recognizing their role in transforming sports into a platform for community-wide violence prevention.
