Maternal health equity in Georgia: a Delphi consensus approach to definition and research priorities.

BACKGROUND: Pregnancy-related mortality in the United States is the greatest among all high-income countries, and Georgia has one of the highest maternal mortality rates-almost twice the national rate. Furthermore, inequities exist in rates of pregnancy-related deaths. In Georgia, non-Hispanic Black women are nearly 3 times more likely to die from pregnancy-related complications than non-Hispanic White women. Unlike health equity, a clear definition of maternal health equity is lacking, overall and in Georgia specifically, but is needed to reach consensus and align stakeholders for action. Therefore, we used a modified Delphi method to define maternal health equity in Georgia and to determine research priorities based on gaps in understanding of maternal health in Georgia. METHODS: Thirteen expert members of the Georgia Maternal Health Research for Action Steering Committee (GMHRA-SC) participated in an iterative, consensus-driven, modified Delphi study comprised of 3 rounds of anonymous surveys. In round 1 (web-based survey), experts generated open-ended concepts of maternal health equity and listed research priorities. In rounds 2 (web-based meeting) and 3 (web-based survey), the definition and research priorities suggested during round 1 were categorized into concepts for ranking based on relevance, importance, and feasibility. Final concepts were subjected to a conventional content analysis to identify general themes. RESULTS: The consensus definition of maternal health equity created after undergoing the Delphi method is: maternal health equity is the ultimate goal and ongoing process of ensuring optimal perinatal experiences and outcomes for everyone as the result of practices and policies free of interpersonal or structural bias that tackle current and historical injustices, including social, structural, and political determinants of health impacting the perinatal period and life course. This definition highlights addressing the current and historical injustices manifested in the social determinants of health, and the structural and political structures that impact the perinatal experience. CONCLUSION: The maternal health equity definition and identified research priorities will guide the GMHRA-SC and the broader maternal health community for research, practice, and advocacy in Georgia.

Prevalence and predictors of symptoms of Perinatal Mood and anxiety Disorders among a sample of Urban Black Women in the South.

OBJECTIVES: Data are scarce regarding the prevalence and predictors of perinatal mood and anxiety disorders (PMADs) among Black women. The purpose of this study was to examine the prevalence and predictors of symptoms of PMADS among Black women. METHODS: Black women completed a paper survey between August 2019 and October 2019. Binomial logistic regression was employed to examine predictors of PMAD symptoms. RESULTS: The prevalence of symptoms of PMADs was 56%. A higher proportion of women with PMADs had experienced depression (16% vs. 32%, p = 0.006); physical (18% vs. 31%, p = 0.030), emotional (35% vs. 61%, p = 0.000), or sexual abuse (12% vs. 29%, p = 0.002); and symptoms of depression or anxiety before pregnancy (18% vs. 46%, p = 0.000). After adjusting for socio-demographics in multivariate analysis, experiencing symptoms of depression or anxiety before pregnancy (adjusted odds ratio [aOR] = 3.445, p = 0.001) was positively associated with experiencing symptoms of PMADs, whereas higher levels of self-esteem (aOR = 0.837, p = 0.000) were negatively associated with experiencing symptoms of perinatal mood and anxiety disorders. CONCLUSIONS FOR PRACTICE: The prevalence of PMAD symptoms among this sample of Black women was alarmingly high. Women who experienced PMADs were more likely to report adverse childhood experiences (e.g., physical, emotional, and/or sexual abuse). By understanding the prevalence of PMADs and the factors associated with these disorders, healthcare professionals can improve diagnosis and treatment rates among this understudied and underserved population.

Developing Culturally Tailored mHealth Tools to Address Sexual and Reproductive Health Outcomes Among Black and Latina Women: A Systematic Review.

BACKGROUND: In addressing the sexual and reproductive health (SRH) disparities for Black and Latina women, there is a need for the development of innovative programs, framed using theoretical underpinnings that are culturally and contextually tailored so that they align with lived experiences. Mobile health (mHealth) interventions offer considerable potential as a means of providing effective SRH education and services. However, there has been a lack of research assessing culturally and contextually tailored mHealth SRH interventions for Black and Latina women. METHOD: A comprehensive literature search was undertaken using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Literature was reviewed to evaluate whether a culturally and contextually tailored approach was utilized in the development and implementation of mHealth interventions for Black and Latina women. RESULTS: A total of 12 articles were included in our synthesis, which encompassed mobile phone-, telephone-, and computer-based mHealth interventions for Black and Latina women. Cultural and/or gender-specific tailoring was included in 10 studies. Reduction of risky sexual behaviors and increased contraception usage were reported in 92% (n = 11) of the studies. Interventions that incorporated tailored content and fostered interaction reported high rates of follow-up. CONCLUSIONS: Tailored mHealth interventions can be effective in promoting behavior change and improving SRH outcomes for Black and Latina women. However, there is a need for more research assessing user engagement and retention for Black and Latina women, and whether improvements in SRH outcomes are sustainable over the long term.

The impact of COVID-19 among Black women: evaluating perspectives and sources of information.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) has burgeoned into a pandemic that highlights the countless social and health disparities that have existed in Black communities within the United States for centuries. Recent epidemiological data show that Black communities are being disproportionately impacted by COVID-19, resulting in higher morbidity and mortality rates compared to other racial and ethnic groups. For Black women in particular, a long-standing history of systemic racism and marginalization has resulted in increased vulnerability and susceptibility to certain adverse health outcomes. Recent data show that COVID-19 knowledge rates among Black participants are low, and that Black women who become infected with COVID-19 have higher risks of complications and mortality compared to their non-Black counterparts. Given this data, there is a need to explore where and how Black women are obtaining information that pertains to COVID-19, along with the impacts that COVID-19 may be having on their daily lives. DESIGN: We conducted interviews with 15 Black women who are clients at a community-based family service center to assess their understanding of COVID-19, determine how they were obtaining COVID-19 information, and evaluate the various impacts that COVID-19 was having on their lives. An initial codebook was developed based on the recorded interviews which included deductive and inductive codes. A thematic analysis of the data was then conducted using MaxQDA (Verbi Software), focusing on Black women's experiences related to COVID-19. RESULTS: The majority of participants were using a combination of social media platforms and news sources to obtain information about COVID-19. Most participants (79%) expressed confusion, misunderstanding, and mistrust of the information that they were receiving about COVID-19. CONCLUSION: In addressing COVID-19-related health disparities within Black communities, it is imperative for trusted entities and organizations within Black communities to provide accurate and tailored information regarding this novel virus.

The pre-exposure prophylaxis (PrEP) consciousness of black college women and the perceived hesitancy of public health institutions to curtail HIV in black women.

BACKGROUND: Consistent use of Pre-Exposure Prophylaxis (PrEP), a biomedical intervention for HIV seronegative persons, has been shown to significantly decrease HIV acquisition. Black women are a viable population segment to consider for PrEP use as their HIV incidence is overwhelmingly higher than all other women groups. METHODS: We developed and piloted a cultural- and age- appropriate PrEP education intervention to determine Black college women's: 1) perceptions of and receptivity to PrEP use; and 2) preferences for PrEP information delivery. RESULTS: We recruited N = 43 Black college women. Most of our sample were sophomore and Juniors of whom identified as heterosexual (83%) and single (67%). Over 50% of young women had never been HIV tested and only 28% had been tested in the last 6 months; however, 100% of the women believed their HIV status was negative. Prior to participating in the study, most Black college women (67%) had not heard about PrEP and were unsure or apprehensive (72%) to initiate PrEP. The Black college women indicated that our educational intervention was extremely helpful (67%) for understanding and learning about PrEP. Post participating in our PrEP education module, regardless of delivery modality, participants reported being likely (62.55-70%) to initiate PrEP in the future. CONCLUSIONS: Results indicate that Black college women would strongly consider PrEP when provided with basic knowledge, regardless of delivery modality. Participants also showed greater appreciation for in-person delivery and found it to be significantly more helpful and of greater quality for learning about PrEP; comprehension or perceived usefulness of PrEP-related content was relatively the same between groups. PrEP content delivery -- via in-person or online methods - is contingent on learning style and presentation. TRIAL REGISTRATION: This study has been registered under the ISRCTN Registry as of July 6, 2020. The trial registration number is ISRCTN14792715 . This study was retrospectively registered.

Young adult US-born Latina women's thoughts, feelings and beliefs about unintended pregnancy.

Current measures of unintended pregnancy underestimate the co-occurring, complex set of social, cultural, economic and structural factors that influence how women interpret unintended pregnancy. The purpose of this study was to prospectively explore young adult US-born Latinas' thoughts, feelings and beliefs about pregnancy, specifically unintended pregnancies and the sociocultural factors identified as contributors to those beliefs. In-depth interviews (n = 20) were conducted with US-born, English-speaking Latinas aged 18-25 years in south Florida. Seventeen participants did not intend to get pregnant, while the remaining participants (n = 3) reported that their intentions kept changing. Participants' beliefs regarding their unintended pregnancy were influenced by social and economic hardship and cultural factors such as fatalism and familismo. Ideas and the meaning of pregnancy differed based on the woman's pregnancy resolution decision. Many women felt the term 'unintended pregnancy' placed blame on women and was stigmatising. When discussing pregnancy planning, most participants felt that women should not plan their pregnancies and doing so was going against fate. Findings suggest that salient influences such as culture and the social determinants related to unintended pregnancy should be incorporated into measurements examining unintended pregnancy.

HPV Vaccine recommendations: does a health care provider's gender and ethnicity matter to Unvaccinated Latina college women?

Objectives: There are disparities in the uptake of HPV vaccine among racial/ethnic minority women. The strongest predictor of HPV vaccine uptake among adult women is health care provider (HCP) recommendation; however, it is unclear how issues relating to race/ethnicity may mitigate these recommendations. Research shows that racial/ethnic and gender concordance between a patient and HCP can improve patient satisfaction, access and quality of care. If concordance contributes to improved patient-provider interactions, then it may be a factor in patient decisions regarding HPV vaccination. The objectives of this study were to (1) explore gender and ethnicity HCP preference regarding HPV vaccination among unvaccinated; and (2) understand factors associated with those preferences. Design: Unvaccinated Latina college students (n = 187) completed a survey that assessed HCP preferences, medical mistrust, cultural assimilation and HPV vaccine recommendation. Logistic regression models evaluated associations between above variables with HPV knowledge and preference for a female and/or Latina HCP. Results: Most respondents had health insurance (71%), a regular HCP (64%), were US-born (67%), with foreign-born parents (74%). Thirty-four percent and 18% agreed that they would be more likely to get the HPV vaccine if the recommending HCP was female and Latino, respectively. Latina women reporting higher medical mistrust preferred a HPV vaccine recommendation from a Latino/a provider. Conclusions: Latinas' preferences regarding gender and ethnicity of their HCPs may affect patient-provider interactions. Increasing diversity and cultural awareness among HCPs, and providing linguistically and culturally-appropriate information may decrease patient-provider mistrust, increase uptake of the HPV vaccine, and decrease persistent cervical cancer disparities.

Depression severity is associated with increased inflammation in veterans with peripheral artery disease.

The present study examines the association between depressive symptoms and inflammatory markers in peripheral artery disease (PAD) to better understand the mechanistic relationship between depression and PAD. A cross-sectional sample of 117 patients with PAD (97% male, 76% Caucasian) was recruited from the San Francisco Veterans Affairs Medical Center. Patients were categorized into three subgroups based upon current depressive symptom severity, as defined by Patient Health Questionnaire-8 scores: no symptoms (score of 0-4, n = 62), mild symptoms (score of 5-9, n = 33), and moderate/severe symptoms (score ≥ 10, n = 22). Serum levels of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), soluble intercellular adhesion molecule-1 (ICAM-1), and tumor necrosis factor-alpha (TNF-α) were assayed and log-transformed for multivariable analysis. To decrease the possibility of Type 1 errors, inflammatory markers were standardized and summed to create a total inflammatory score. In a multivariable analysis controlling for demographics, PAD severity, and atherosclerotic risk factors, mild and moderate/severe depressive symptoms were predictive of a higher total inflammatory score when compared to the group with no symptoms (mild symptoms p = 0.04, moderate/severe symptoms p = 0.007). Exploratory multivariable analyses of individual inflammatory markers found IL-6 levels were significantly higher in the moderate/severe symptoms group ( p = 0.006) than in the no symptoms group. Moreover, hs-CRP and ICAM-1 trended upwards with increasing depression severity. TNF-α was not associated with depression severity. We conclude that depressive symptom severity was independently associated with greater inflammation in PAD. Future research should examine the strength and directionality of this association through larger prospective cohort studies, as well as investigate the pathophysiological mechanisms responsible.

Oral Health Intervention for Low-Income African American Men in Atlanta, Georgia.

OBJECTIVES: To describe the Minority Men's Oral Health Dental Access Program (MOHDAP) intervention and report participants' outcomes and satisfaction. METHODS: MOHDAP was designed to increase the oral health knowledge of low-income, African American men in Atlanta, GA, in 2013. A community-based participatory approach and needs assessment guided the intervention development, which consisted of 3 educational modules delivered over a 2-day period. All participants (n = 45; mean age = 50 years) were African American men. We assessed changes in oral health knowledge and attitudes at baseline and postintervention via survey. RESULTS: After the intervention, the percentage of correct responses to questions about gingivitis increased by 24.2% (P = .01), about use of a hard (instead of a soft) toothbrush increased by 42.2% (P < .01), and knowledge of ways to prevent gum diseases increased by 16.0% (P = .03). The percentage agreeing with erroneous statements decreased 11.3% (P = .02) regarding oral health-related fatalism and oral health self-care and 17.4% (P = .05) regarding saving front versus back teeth. CONCLUSIONS: Community-based oral health educational interventions designed for African American men may reduce oral health disparities among this population.

Genes related to mitochondrial functions are differentially expressed in phosphine-resistant and -susceptible Tribolium castaneum.

BACKGROUND: Phosphine is a valuable fumigant to control pest populations in stored grains and grain products. However, recent studies indicate a substantial increase in phosphine resistance in stored product pests worldwide. RESULTS: To understand the molecular bases of phosphine resistance in insects, we used RNA-Seq to compare gene expression in phosphine-resistant and susceptible laboratory populations of the red flour beetle, Tribolium castaneum. Each population was evaluated as either phosphine-exposed or no phosphine (untreated controls) in triplicate biological replicates (12 samples total). Pairwise analysis indicated there were eight genes differentially expressed between susceptible and resistant insects not exposed to phosphine (i.e., basal expression) or those exposed to phopshine (>8-fold expression and 90 % C.I.). However, 214 genes were differentially expressed among all four treatment groups at a statistically significant level (ANOVA, p < 0.05). Increased expression of 44 cytochrome P450 genes was found in resistant vs. susceptible insects, and phosphine exposure resulted in additional increases of 21 of these genes, five of which were significant among all treatment groups (p < 0.05). Expression of two genes encoding anti-diruetic peptide was 2- to 8-fold reduced in phosphine-resistant insects, and when exposed to phosphine, expression was further reduced 36- to 500-fold compared to susceptible. Phosphine-resistant insects also displayed differential expression of cuticle, carbohydrate, protease, transporter, and many mitochondrial genes, among others. Gene ontology terms associated with mitochondrial functions (oxidation biological processes, monooxygenase and catalytic molecular functions, and iron, heme, and tetrapyyrole binding) were enriched in the significantly differentially expressed dataset. Sequence polymorphism was found in transcripts encoding a known phosphine resistance gene, dihydrolipoamide dehydrogenase, in both susceptible and resistant insects. Phosphine-resistant adults also were resistant to knockdown by the pyrethroid deltamethrin, likely due to the increased cytochrome P450 expression. CONCLUSIONS: Overall, genes associated with the mitochondria were differentially expressed in resistant insects, and these differences may contribute to a reduction in overall metabolism and energy production and/or compensation in resistant insects. These data provide the first gene expression data on the response of phosphine-resistant and -susceptible insects to phosphine exposure, and demonstrate that RNA-Seq is a valuable tool to examine differences in insects that respond differentially to environmental stimuli.

Sex Differences in Branched-chain Amino Acid and Tryptophan Metabolism and Pathogenesis of Youth-onset Type 2 Diabetes.

OBJECTIVES: Insulin resistance is associated with elevations in plasma branched-chain amino acids (BCAAs). BCAAs compete with aromatic amino acids including tryptophan for uptake into ß cells. To explore relationships between BCAAs and tryptophan metabolism, adiposity, and glucose tolerance, we compared urine metabolites in overweight/obese youth with type 2 diabetes (T2D) with those in nondiabetic overweight/obese and lean youth. METHODS: Metabolites were measured in 24-hour and first-morning urine samples of 56 nondiabetic adolescents with overweight/obesity, 42 adolescents with T2D, and 43 lean controls, aged 12 to 21 years. Group differences were assessed by Kruskal Wallis or ANOVA. RESULTS: Groups were comparable for age, pubertal status, and ethnicity. Youth with T2D were predominantly female and had highest percent body fat. BCAAs, branched-chain ketoacids (BCKAs), tryptophan, and kynurenine were higher in urine of subjects with T2D. There were no differences between lean controls and nondiabetic youth with overweight/obesity. T2D was associated with diversion of tryptophan from the serotonin to the kynurenine pathway, with higher urinary kynurenine/serotonin ratio and lower serotonin/tryptophan and 5-HIAA/kynurenine ratios. Urinary BCAAs, BCKAs, tryptophan, and ratios reflecting diversion to the kynurenine pathway correlated positively with metrics of body fat and hemoglobin A1c. Increases in these metabolites in the obese T2D group were more pronounced and statistically significant only in adolescent girls. CONCLUSION: Increases in urinary BCAAs and BCKAs in adolescent females with T2D are accompanied by diversion of tryptophan metabolism from the serotonin to the kynurenine pathway. These adaptations associate with higher risks of T2D in obese adolescent females than adolescent males.

Cave sediment sequesters anthropogenic microparticles (including microplastics and modified cellulose) in subsurface environments.

Anthropogenic microparticles (of synthetic, semisynthetic, or modified natural compositions) are globally pervasive, yet little is known about their distribution and storage in the subsurface despite their potential threats to belowground environments. We therefore assessed their amounts and characteristics in water and sediment from a cave in the United States. During a flood, water and sediment samples were collected at 8 sites every ~25 m along the cave passageways. Both sample types were evaluated for anthropogenic microparticles, while water was assessed for geochemistry (e.g., inorganic species) and sediment was evaluated for particle sizes. Additional water samples were collected during low flow at the same sites for further geochemical analysis to determine water provenance. We found anthropogenic microparticles in all samples that were mainly fibers (91 %) and clear (59 %). Both suspected (identified visually) and confirmed (identified with Fourier transform infrared spectroscopy; FTIR) anthropogenic microparticle concentrations were positively correlated between the compartments (r ≥ 0.83, p ≤ 0.01), but quantities in sediment were ~100 times those in water. These findings indicate that sediment sequesters anthropogenic microparticle pollution in the cave. Microplastic concentrations were similar among all sediment samples, but only one water sample at the main entrance contained microplastics. Treated cellulosic microparticle abundances in both compartments generally increased along the cave stream's flowpath, which we suspect is due to both their flood and airborne deposition. Water geochemical and sediment particle size data collected at a branch indicated at least two distinct water sources to the cave. However, anthropogenic microparticle assemblages did not differ between these sites, implying minimal variation in sourcing across the recharge area. Our results reveal that anthropogenic microparticles intrude karst systems and are stored in sediment. Karstic sediment consequently represents a potential source of "legacy" pollution to the water resources and fragile habitats found in these globally distributed landscapes.

Global Cross-Sectional Study Evaluating the Attitudes towards a COVID-19 Vaccine in Pregnant and Postpartum Women.

Pregnant and postpartum women have an increased risk of severe complications from COVID-19. Many clinical guidelines recommend vaccination of these populations, and it is therefore critical to understand their attitudes toward COVID-19 vaccines. We conducted a cross-sectional online survey in November 2020 of currently pregnant and ≤1-year postpartum women in Brazil, India, the United Kingdom (UK), and the United States (US) that assessed their openness to COVID-19 vaccines and reasons for vaccine hesitancy. Logistic regression analyses were conducted to evaluate openness to receiving a vaccine. Out of 2010 respondents, 67% were open to receiving a COVID-19 vaccine themselves. Among pregnant and postpartum participants, 72% and 57% were willing to receive a vaccine, respectively. Vaccine openness varied significantly by country: India (87%), Brazil (71%), UK (59%), and US (52%). Across all participants, among the 33% who were unsure/not open to receiving a COVID-19 vaccine, the most common reason cited was safety/side effect concerns (51%). Participants were similarly open to their children/other family members receiving a COVID-19 vaccine. Presence of a comorbidity, a positive COVID-19 test result, and pregnancy were all significantly associated with positive vaccine acceptance. Targeted outreach to address pregnant and postpartum women's concerns about the COVID-19 vaccine is needed.

"I care about sex, I care about my health": A mixed-methods pre-test of a HIV prevention mobile health app for Black women in the southern United States.

BACKGROUND: Black women experience higher rates of adverse sexual and reproductive health and HIV outcomes, however the use of mHealth to address these health disparities in this population has been inadequate. This study involved a one-month pre-test with Black women living in metro-Atlanta to evaluate the usability, acceptability, and engagement of an HIV prevention app SavvyHER. METHODS: An explanatory mixed-methods design was employed in which quantitative data was collected through weekly cross-sectional surveys, and qualitative data was collected through semi-structured in-depth interviews. Descriptive and ANOVA analysis was conducted for the quantitative data using STATA software. Qualitative data was analyzed through qualitative descriptive methods on Atlas.ti. RESULTS: Participants had high levels of acceptability towards the app and used SavvyHER moderately. The most frequently used features were live groups (2.96 ±0.22, 95% CI 2.51,3.41), viewing resources and educational information (2.77 ± 0.21, 95% CI 2.33,3.20), and mental health monitoring (2.73 ±0.21, 95% CI 2.29,3.12). The least used features were pregnancy symptom monitoring (1.92 ±0.27, 95% CI 1.38,2.47) and STI symptom monitoring (2.0 ±0.25, 95% CI 1.48,2.52). In qualitative interviews, several women discussed how the ability to engage in active discussions and join live sessions with other end-users was a favorable aspect of SavvyHER. Although the app's primary focus was on sexual and reproductive health and HIV prevention, women were more likely to access mental health monitoring and physical activity monitoring features. Women expressed their fondness of the app design and interface as it was reflective of the diversity of Black women. CONCLUSION: Further research is needed to explore the efficacy in using SavvyHER and additional mHealth interventions to enhance Black women's sexual and reproductive health and overall wellness.

Digital Health App to Address Disparate HIV Outcomes Among Black Women Living in Metro-Atlanta: Protocol for a Multiphase, Mixed Methods Pilot Feasibility Study.

BACKGROUND: Cisgender Black women in the southern United States are at heightened risk for HIV and adverse sexual and reproductive health outcomes. Mobile health interventions that target HIV risk while being adapted to the needs and lived experiences of Black women are remarkably limited. OBJECTIVE: The study aims to refine SavvyHER, a mobile app for HIV prevention, with Black women residing in high HIV incidence areas of Georgia and evaluate the feasibility, acceptability, and usability of SavvyHER. This paper describes the procedures implemented to conduct this research. METHODS: Community-based participatory research tenets guide this multiphase study to finalize the development of what we hypothesize will be an effective, sustainable, and culturally relevant HIV prevention and optimal sexual health and reproductive wellness app for Black women. This multiphased, mixed methods study consists of 3 phases. The first phase entails focus groups with Black women to understand their preferences for the functionality and design of a beta prototype version of SavvyHER. In the second phase, an app usability pretest (N=10) will be used to refine and optimize the SavvyHER app. The final phase will entail a pilot randomized controlled trial (N=60) to evaluate the app's feasibility and usability in preparation for a larger trial. RESULTS: Findings from preliminary focus groups revealed educational content, app aesthetics, privacy considerations, and marketing preferred by Black women, thus informing the first functional SavvyHER prototype. As we adapt and test the feasibility of SavvyHER, we hypothesize that the app will be an effective, sustainable, and culturally relevant HIV prevention, sexual health, and reproductive wellness tool for Black women. CONCLUSIONS: The findings from this research substantiate the importance of developing health interventions curated for and by Black women to address critical HIV disparities. The knowledge gained from this research can reduce HIV disparities among Black women through a targeted intervention that centers on their health needs and priorities.

Profiling the Somatic Mutational Landscape of Breast Tumors from Hispanic/Latina Women Reveals Conserved and Unique Characteristics.

Somatic mutational profiling is increasingly being used to identify potential targets for breast cancer. However, limited tumor-sequencing data from Hispanic/Latinas (H/L) are available to guide treatment. To address this gap, we performed whole-exome sequencing (WES) and RNA sequencing on 146 tumors and WES of matched germline DNA from 140 H/L women in California. Tumor intrinsic subtype, somatic mutations, copy-number alterations, and expression profiles of the tumors were characterized and compared with data from tumors of non-Hispanic White (White) women in The Cancer Genome Atlas (TCGA). Eight genes were significantly mutated in the H/L tumors including PIK3CA, TP53, GATA3, MAP3K1, CDH1, CBFB, PTEN, and RUNX1; the prevalence of mutations in these genes was similar to that observed in White women in TCGA. Four previously reported Catalogue of Somatic Mutations in Cancer (COSMIC) mutation signatures (1, 2, 3, 13) were found in the H/L dataset, along with signature 16 that has not been previously reported in other breast cancer datasets. Recurrent amplifications were observed in breast cancer drivers including MYC, FGFR1, CCND1, and ERBB2, as well as a recurrent amplification in 17q11.2 associated with high KIAA0100 gene expression that has been implicated in breast cancer aggressiveness. In conclusion, this study identified a higher prevalence of COSMIC signature 16 and a recurrent copy-number amplification affecting expression of KIAA0100 in breast tumors from H/L compared with White women. These results highlight the necessity of studying underrepresented populations. SIGNIFICANCE: Comprehensive characterization of genomic and transcriptomic alterations in breast tumors from Hispanic/Latina patients reveals distinct genetic alterations and signatures, demonstrating the importance of inclusive studies to ensure equitable care for patients.

Let Me Prep You to PREP Me: Amplifying the Voices of Black Women and Their Providers to Consider PrEP as an HIV Prevention Option.

Despite the high efficacy of pre-exposure prophylaxis (PrEP) in preventing HIV acquisition, PrEP uptake among Black cisgender women remains low. Our qualitative study assessed Black cisgender women's perspectives, attitudes, and acceptability towards PrEP, in addition to exploring PrEP-related attitudes, facilitators, and barriers to PrEP access among health care staff. This study was conducted to ascertain data to inform the development of our HIV prevention app-Savvy HER-which is being designed for Black cisgender women. Our findings indicated that Black women had low levels of PrEP acceptability and high levels of misconceptions, inaccurate knowledge, and stigma towards PrEP. Health care providers in our sample confirmed barriers of stigma, misconceptions, and knowledge among their patients coupled with difficulty accessing PrEP due to structural barriers. Our study indicated that there is a critical need to heighten Black cisgender women's PrEP knowledge and HIV risk perception in order to increase PrEP acceptability and uptake.

Community-led research for reproductive justice: Exploring the SisterLove Georgia Medication Abortion project.

Introduction: While reproductive injustice indicators are improving globally, they are worsening in the United States particularly for Black and other marginalized communities. Eugenics and obstetric violence against low-income and communities of color create well-founded distrust of sexual and reproductive health (SRH). Transformational, reparative ways of conducting SRH research are needed. Proposed principles of community-led research for reproductive justice: Drawing on our collective experience as reproductive justice leaders, SRH researchers, and clinicians, we propose the following principles of community-led research for reproductive justice: 1) Center the marginalized community members most affected by SRH inequities as leaders of research; 2) Facilitate equitable, collaborative partnership through all phases of SRH research; 3) Honor multiple ways of knowing (experiential, cultural, empirical) for knowledge justice and cross-directional learning across the team; 4) Build on strengths (not deficits) within the community; 5) Implement the tenets of reproductive justice including structural-level analysis and the human rights framework; 6) Prioritize disseminating useful findings to community members first then to other audiences; 7) Take action to address social and reproductive injustices. SisterLove's community-led georgia medication abortion project: We offer the community-led Georgia Medication Abortion (GAMA) Project by reproductive justice organization SisterLove from 2018-2022 as a case study to demonstrate these principles along with the strengths and challenges of reproductive justice research. Discussion: Community-led reproductive justice research offers innovative and transformational methods for truly advancing SRH in an era of increasing policy restrictions and decreasing access to care. Yet existing funding, research administrative, and publishing systems will require structural change.

Integrating land cover, point source pollution, and watershed hydrologic processes data to understand the distribution of microplastics in riverbed sediments.

Microplastics are emerging contaminants ubiquitously distributed in the environment, with rivers acting as their main mode of transport in surface freshwater systems. However, the relative importance of hydrologic processes and source-related variables for benthic microplastic distribution in river sediments is not well understood. We therefore sampled and characterized microplastics in river sediments across the Meramec River watershed (eastern Missouri, United States) and applied a hydrologic modeling approach to estimate the relative importance of river discharge, river sediment load, land cover, and point source pollution sites to understand how these environmental factors affect microplastic distribution in benthic sediments. We found that the best model for the Meramec River watershed includes both source-related variables (land cover and point sources) but excludes both hydrologic transport-related variables (discharge and sediment load). Prior work has drawn similar and dissimilar conclusions regarding the importance of anthropogenic versus hydrologic variables in microplastic distribution, though we acknowledge that comparisons are limited by methodological differences. Nevertheless, our findings highlight the complexity of microplastic pollution in freshwater systems. While generating a universal predictive model might be challenging to achieve, our study demonstrates the potential of using a modeling approach to determine the controlling factors for benthic microplastic distribution in fluvial systems.
