RESUMEN
BACKGROUND: The maternal mortality rate (MMR) in the United States (USA) continues to increase despite medical advances and is exacerbated by stark racial disparities. Black women are disproportionately affected and are three times more likely to experience a pregnancy-related death (PRD) compared to Non-Hispanic White (NHW) women. METHODS: A literature review was conducted to examine the racial disparities in the United States' MMR, specifically among pregnant Black women. PubMed and key organizations (World Health Organization, Center for Disease Control and Prevention, American College of Obstetricians and Gynecologists, Alliance for Innovation on Maternal Health, Association of American Medical Colleges, U.S. Census Bureau, and U.S. Congress) were searched for publications after 2014. RESULT: Forty-two articles were reviewed to identify the role of structural racism, implicit biases, lack of cultural competence, and disparity education on pregnant Black women. This review highlights that maternal health disparities for Black women are further impacted by both structural racism and racial implicit biases. Cultural competence and educational courses targeting racial disparities among maternal healthcare providers (MHCP) are essential for the reduction of PRDs and pregnancy-related complications (PRC) among this target population. Additionally, quality and proper continuity of care require an increased awareness surrounding the risk of cardiovascular diseases for pregnant Black women. CONCLUSIONS: The surging MMR for Black women is a public health crisis that requires a multi-tiered approach. Interventions should be implemented at the provider and healthcare institution level to dismantle implicit biases and structural racism. Improving patient-provider relationships through increased cultural competency and disparity education will increase patient engagement with the maternal healthcare (MHC) system.
RESUMEN
Area deprivation index (ADI) is associated with the risk of severe COVID-19 in adults. However, this association has not been established in children. Information on ADI, demographics, clinical features, disease severity, and outcomes was analyzed for 3434 children with COVID-19. A multivariate logistic regression revealed that non-Hispanic Asians, extremes of weight, and higher ADI were associated with severe disease.

BACKGROUND AND OBJECTIVES: Promoting positive child and youth health and development requires clear definitions and comprehensive measures of child and youth thriving. The study's objectives were to identify the scope, range, and gaps in definitions and measures of thriving for children or youth (birth through young adult). METHODS: Systematic searches of Pubmed, PsycInfo, Health and Psychosocial Instruments, Education Resources Information Center, and Scopus were conducted for articles that included definitions, conceptual frameworks, or measures of child and youth thriving. Inclusion criteria were that the articles: (1) provided a new definition or measure of child thriving, flourishing, or well-being; (2) focused on normally developing children 0 to 24 years old; and (3) were published between 2009 and 2022 in an English language peer-reviewed journal. Studies were categorized by child age, study type, population, and community-identified domains of thriving. RESULTS: Of the 14 920 articles identified, 113 met inclusion criteria: 34 unique definitions or frameworks, 66 validated measures, and 12 articles presenting both a framework and measure. One-third of the articles focused on early childhood (0-5 years old); 47% on middle childhood (6-11 years old); 72% on adolescence (12-17 years old), and 22% on young adults (18-24 years old). CONCLUSIONS: Current child thriving definitions, frameworks, and measures could be expanded in their coverage of age and key domains, such as racial equity and safety. Additional frameworks and measures focused on early childhood (0-5 years) and assessing thriving over time are needed.

The COVID-19 pandemic has highlighted structural inequities that are barriers to thriving for children in neighborhoods with concentrated disadvantage. Health systems are increasingly addressing health-related social needs. The "Pittsburgh Study" is a longitudinal, community-partnered study focused on child and adolescent thriving and racial equity. This initiative will elucidate critical influences on childhood health and thriving, evaluate developmentally appropriate interventions to improve outcomes from birth to high school, and establish a child health data hub. Integration of community members into scientific inquiry, rapid data-to-action cycles, and workforce development are strategies health systems may consider to enhance child health equity.
RESUMEN
BACKGROUND: Beyond the sweeping physiological effects of COVID-19 infections in 2020 and 2021, the psychosocial impacts of lockdowns, social distancing, and the associated disruptions to daily life have brought on a simultaneous mental health crisis, particularly among many working mothers who are disproportionately balancing childcare, virtual schooling, and employment vulnerability. The aim of this study was to measure the mental health status of working mothers in the United States and associations with the provision of family-friendly employment benefits one year into the pandemic. METHODS: Cross-sectional data were collected from a sample of working mothers in the U.S. using an online survey of mental health status and the receipt of employer-provided family-friendly benefits. Mental health was measured with the Kessler 6 (K-6) and the Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS). Perceived helpfulness of benefits was assessed through self-reported Likert-scale scores of 0 (not at all helpful) to 4 (extremely helpful) to determine mean helpfulness scores for benefit types. Multivariable logistic regression analyses were conducted to determine associations between receipt of employment benefits and serious mental illness (SMI). RESULTS: A total of 728 participants met the study criteria, 83.7% were non-Hispanic/Latino white and 61.1% were 35-44 years of age. Among study participants, 54.3% (n = 395) and 21.8% (n = 159) reported psychological distress levels associated with moderate mental illness (MMI) and serious mental illness (SMI), respectively. Not receiving benefits was associated with a 50% increase in odds of SMI (aOR = 1.50, 95% CI [1.03-2.20], p = 0.036). Benefits perceived to be the most helpful for participants were flexible hours/schedule (3.5; SD ± 0.9), flexible work location (3.3; SD ± 1.1), and supplemental paid time off (3.1; SD ± 1.1), with mean scores above very helpful. CONCLUSION: Results suggest employment benefits may help support the mental health of working mothers and provide a call to action to employers and policy stakeholders to develop solutions addressing gaps in workplace benefits and mental health support for working parents, with sustainable reform in mind to mitigate employment benefit inequities exposed by the pandemic.

BACKGROUND: The degree to which children experience unmet need for dental care during the COVID-19 pandemic and its association with pandemic-related household job or income loss are unknown. METHODS: The authors performed a cross-sectional household survey of 348 families in Pittsburgh, Pennsylvania, from June 25 through July 2, 2020. Unmet need for child dental care and pandemic-related household job or income loss were assessed using caregiver self-report. RESULTS: Caregivers reported that the greatest unmet child health care need during the COVID-19 pandemic was dental care (16%), followed by medical care for a well visit or vaccination (5%). Approximately 40% of caregivers reported job loss or a decrease in household income due to the COVID-19 pandemic. The authors found a significant association between the probability of unmet child dental care and pandemic-related household job or income loss (P = .022). Losing a job or experiencing a decrease in income due to the COVID-19 pandemic was associated with unmet child dental care (relative risk, 1.77; 95% confidence interval, 1.08 to 2.88). CONCLUSIONS: In this sample, 3 times as many households reported unmet dental care for a child compared with unmet medical care. Unmet child dental care was more common in households where pandemic-related job or income loss occurred. PRACTICAL IMPLICATIONS: If unmet dental care continues as a result of the COVID-19 pandemic, nontraditional strategies for delivering dental care can be considered to improve access to dental care for children, such as teledentistry and oral health prevention services in primary care settings.

BACKGROUND: Given the profound inequities in maternal and child health along racial, ethnic, and socioeconomic lines, strength-based, community-partnered research is required to foster thriving children, families, and communities, where thriving is defined as optimal development across physical, mental, cognitive, and social domains. The Pittsburgh Study (TPS) is a community-partnered, multi-cohort study designed to understand and promote child and youth thriving, build health equity, and strengthen communities by integrating community partners in study design, implementation, and dissemination. TPS launched the Tracking Health, Relationships, Identity, EnVironment, and Equity (THRIVE) Study to evaluate children's developmental stages and contexts from birth through completion of high school and to inform a child health data hub accessible to advocates, community members, educators, health professionals, and policymakers. METHODS AND ANALYSIS: TPS is rooted in community-partnered participatory research (CPPR), health equity, antiracism, and developmental science. Using our community-informed conceptual framework of child thriving, the THRIVE Study will assess cross-cutting measures of place, environment, health service use, and other social determinants of health to provide longitudinal associations with developmentally appropriate child and youth thriving outcomes across participants in six cohorts spanning from pregnancy through adolescence (child ages 0-18 years). Data from electronic health records, school records, and health and human services use are integrated to assess biological and social influences of thriving. We will examine changes over time using paired t-tests and adjusted linear regression models for continuous thriving scores and McNemar tests and adjusted logistic regression models for categorical outcomes (thriving/not thriving). Data analyses will include mixed models with a random intercept (in combination with the previously-specified types of regression models) to account for within-subject correlation. DISCUSSION: By enhancing assessment of child and youth well-being, TPS will fill critical gaps in our understanding of the development of child and youth thriving over time and test strategies to support thriving in diverse communities and populations. Through CPPR and co-design, the study aims to improve child health inequities across multiple socioecological levels and developmental domains.
RESUMEN
OBJECTIVE: To identify unmet health and social resource needs during a county-wide coronavirus disease 19 (COVID-19) stay-at-home order and phased re-opening in Western Pennsylvania. METHODS: With public health, social service, and community partners connected through an ongoing academic-community collaborative, we developed and fielded a weekly repeated cross-sectional electronic survey assessing usage of and unmet need for health and social service resources. Using 10 weeks of surveys (April 3-June 11, 2020) by Allegheny County residents, we examined variation in responses by week and by sociodemographic characteristics using chi-square tests. We shared written reports weekly and discussed emerging trends with community partners. RESULTS: Participants ranged from 229 to 1001 per week. Unmet need for at least 1 health or health-related social need resource varied by week, ranging from 55% (95% confidence interval [CI] 50%-59%) of participants in week 2 to 43% (95% CI 37%-49%) of participants in week 9 (P = .006). Increased use of at least 1 resource ranged from 53% (95% CI 47%-58%) of participants in week 3 to 36% (95% CI 31%-42%) in week 9 (P < .001). Unmet need for food and financial assistance peaked early during the stay-at-home order, while unmet need for mental health care rose later. Unmet need for food assistance varied significantly by race and ethnicity and by household prepandemic income. CONCLUSIONS: Over half of families with children reported unmet health or social service needs during the first month of a county-wide COVID-19 stay-at-home order. Unmet needs varied with race, ethnicity, and income and with duration of the stay-at-home order.

OBJECTIVE: To develop a community-informed definition of child and youth thriving and identify community priorities for child/youth thriving. METHODS: Through concept mapping, a mixed-methods community-based participatory research method, this study examined community and health professionals' conceptualizations of child and youth thriving. We conducted brainstorming, sorting and rating, and interpretation sessions in 3 geographically distinct neighborhoods with concentrated disadvantage; simultaneously, researchers and health professionals participated in online sessions. RESULTS: Participants included 91 community members, health care and social service professionals, and researchers who identified 104 items related to child and youth thriving and grouped these items into 7 distinct clusters. Two clusters focused on child-level factors (Strong Minds and Bodies; Positive Identity and Self-Worth), 2 focused on place-based factors (Healthy Environments; Vibrant Communities), and 3 focused on relationships and interactions between children and their environments (Caring Families and Relationships; Safety; and Fun and Happiness). The community-informed conceptualization of child thriving builds on previous models, adding dimensions of physical health and safety. Participants ranked having "someone to talk to," being "comfortable in their own skin," having "pride in themselves," and having a "strong sense of self and self-worth" as most important to child and youth thriving. CONCLUSIONS: By integrating perspectives of community members from diverse neighborhoods with those of researchers and health professionals, this study captures novel domains to inform a conceptual model of thriving that focuses on stakeholder priorities. Findings will guide development, implementation, and evaluation of community-based interventions and their impact on child and adolescent health and thriving.

Poverty remains a critical predictor of children's school readiness, health and longer term outcomes. Early relational health (ERH) (ie, parenting practices and relationship quality) mediates the impact of poverty on child development, and thus has been the focus of many parenting interventions. Despite the documented efficacy of parenting interventions at reducing poverty-related disparities in child health and development, several key barriers prevent achieving population-level reach to families with young children. In the current paper we highlight several of these barriers including gaining population-level access to young children and families, reaching families only through single points of access, addressing the significant heterogeneity of risk that exists among families living in poverty, as well as addressing each of these barriers in combination. We suggest that understanding and confronting these barriers will allow family-centered interventions to more effectively address issues related to ERH at a population level, which in turn will reduce poverty-related disparities in child development.

PURPOSE: To describe the development of pediatric family relationships measures, with versions for child self-report (8-17 years) and parent-report for children 5-17 years old. Measures were created for integration into the Patient Reported Outcomes Measurement Information System (PROMIS®). METHODS: Semi-structured interviews with 10 experts, 24 children, and 8 parents were conducted to elicit and clarify essential elements of family relationships. A systematic literature review was conducted to identify item concepts representative of each element. The concepts were transformed into items that were iteratively revised based on cognitive interviews (n = 43 children) and item translatability review. Psychometric studies involving 2846 children and 2262 parents were conducted to further refine and validate the instruments. RESULTS: Qualitative procedures supported the development of content valid Family Relationships item banks. Final child- and parent-report item banks each contain 47 items. Unidimensional item banks were calibrated using IRT-modeling to estimate item parameters representative of the US population and to enable computerized adaptive test administration. Four- and eight-item short forms were constructed for standard fixed format administration. All instruments have strong internal consistency, retest-reliability, and provide precise estimates of various levels of family relationship quality. Preliminary evidence of the instruments' validity was provided by known-group comparisons and convergence with legacy measures. CONCLUSION: The PROMIS pediatric Family Relationships measures can be applied in research focused on determinants, outcomes, and the protective effects of children's subjective family relationship experiences.

BACKGROUND: Food insecurity remains a public health concern in the United States, particularly among low-income urban ethnically diverse families, even with the Supplemental Nutrition Assistance Program (SNAP). Limited phenomenologic data exist to capture how programmatic changes to SNAP address the needs of users and why a gap in SNAP use may exist. OBJECTIVE: The primary aim of this study was to examine the experiences of low-income, Baltimore, MD, mothers in applying for and maintaining access to SNAP. Secondary aims included understanding participants' perspectives on the influence of changes in SNAP over a 3-year period and how SNAP fits into the overall system of social services for families. DESIGN: In this qualitative, phenomenologic study, in-depth interviews were conducted with 13 mothers and three focus groups with 20 mothers, for a total sample of 33 mothers receiving SNAP benefits. Ten mothers participated in the first round of data collection (January to May 2010), and 23 in the second round (February to May 2013). PARTICIPANTS/SETTING: Participants were 33 mothers receiving SNAP benefits in Baltimore City, MD. MAIN OUTCOME MEASURES: Baltimore SNAP users' experiences with applying for and maintaining access to SNAP, as well as with program changes to the SNAP program. DATA ANALYSIS: Data were analyzed using an iterative emergent design and phenomenologic approach. A constructivist perspective was implemented throughout the coding process. RESULTS: SNAP functioned as a valuable support system within the broader social safety net for mothers living in poverty, yet participants expressed frustration about the processes of applying for and maintaining benefits due to communication problems and poor integration of services. In applying for and accessing SNAP, positive interactions with caseworkers and previous knowledge of the SNAP program were important for maintaining benefits. Interviews and focus group discussions revealed the need for additional outreach and education about the implemented program changes to build trust and improve access to SNAP among participants. CONCLUSIONS: Improving communication and supporting participants' ability to maintain relationships with the same caseworkers, as well as developing better integration with other aid programs, could improve the SNAP program.

BACKGROUND: Maternal depressive symptoms are negatively associated with early child growth in developing countries; however, few studies have examined this relation in developed countries or used a longitudinal design with data past the second year of the child's life. We investigated if and when early maternal depressive symptoms affect average growth in young children up to age 6 in a nationally representative sample of US children. METHODS: Using data from 6,550 singleton births from the Early Childhood Longitudinal Study -- Birth Cohort (ECLS-B), we fit growth trajectory models with random effects to examine the relation between maternal depressive symptoms at 9 months based on the twelve-item version of the Center for Epidemiologic Studies Depression Scale (CES-D) and child height and body mass index (BMI) to age 6 years. RESULTS: Mothers with moderate/severe depressive symptoms at 9 months postpartum had children with shorter stature at this same point in time [average 0.26 cm shorter; 95% CI: 5 cm, 48 cm] than mothers without depressive symptoms; children whose mothers reported postpartum depressive symptoms remained significantly shorter throughout the child's first 6 years. CONCLUSIONS: Results suggest that the first year postpartum is a critical window for addressing maternal depressive symptoms in order to optimize child growth. Future studies should investigate the role of caregiving and feeding practices as potential mechanisms linking maternal depressive symptoms and child growth trajectories.

OBJECTIVE: The aim of our study was to examine whether maternal depressive symptoms at 9 months postpartum adversely affect growth in preschool- and school-aged children. METHODS: We used data from the US nationally representative Early Childhood Longitudinal Study, Birth Cohort. We fit multivariable logistic regression models to study maternal depressive symptoms at 9 months postpartum (using the Center for Epidemiologic Studies Depression Scale) in relation to child growth outcomes, ≤ 10% height-for-age, ≤ 10% weight-for-height, and ≤ 10% weight-for-age at 4 and 5 years. RESULTS: At 9 months, 24% of mothers reported mild depressive symptoms and 17% moderate/severe symptoms. After adjustment for household, maternal, and child factors, children of mothers with moderate to severe levels of depressive symptoms at 9 months' postpartum had a 40% increased odds of being ≤ 10% in height-for-age at age 4 (odds ratio = 1.40, 95% confidence interval: 1.04-1.89) and 48% increased odds of being ≤ 10% in height-for-age at age 5 (odds ratio = 1.48, 95% confidence interval: 1.03-2.13) compared with children of women with few or no depressive symptoms. There was no statistically significant association between maternal depressive symptoms and children being ≤ 1 0% in weight-for-height and weight-for-age at 4 or 5 years. CONCLUSIONS: Maternal depressive symptoms during infancy may affect physical growth in early childhood. Prevention, early detection, and treatment of maternal depressive symptoms during the first year postpartum may prevent childhood height-for-age ≤ 10th percentile among preschool- and school-aged children.

BACKGROUND AND OBJECTIVES: The Mirasol® pathogen reduction technology system for plasma is based on a riboflavin and UV light treatment process resulting in pathogen inactivation due to irreversible, photochemically induced damage of nucleic acids. This study was undertaken to evaluate the possibility of making pathogen reduced cryoprecipitate from riboflavin and UV light- treated plasma that meets the quality requirements specified by UK and European guidelines for untreated cryoprecipitate. MATERIALS AND METHODS: Cryoprecipitate was made from riboflavin and UV light-treated plasma. Plasma units were thawed over a 20 h period at 4°C, and variable centrifugation settings (from 654 g for 2 min to 5316 g for 6 min) were applied to identify the optimal centrifugation condition. Plasma proteins in cryoprecipitate units were characterized on a STA Compact, Diagnostica STAGO and Siemens BCS analyzer. RESULTS: Neither the centrifugation speed or time appeared to have an effect on the quality of the final cryoprecipitate product; however the initial solubilization of the cryoprecipitate product was found to be easier at the lower centrifugation setting (654 g for 2 min). Cryoprecipitate units prepared from Mirasol-treated plasma demonstrated protein levels that were less than levels in untreated products, but were on average 93 IU/unit, 262 mg/unit and 250 IU/unit for FVIII, fibrinogen and von Willebrand ristocetin cofactor activity, respectively. CONCLUSION: Cryoprecipitate products prepared from Mirasol-treated plasma using a centrifugation method contain levels of fibrinogen, FVIII and von Willebrand ristocetin cofactor activity, that meet both the European and UK guidelines for untreated cryoprecipitate. Flexibility in centrifugation conditions should allow blood banks to use their established centrifugation settings to make cryoprecipitate from Mirasol-treated plasma.

BACKGROUND: The Mirasol® Pathogen Reduction Technology (PRT) System for plasma combines riboflavin (vitamin B(2)) and UV light energy to reduce pathogens in plasma products. This study evaluated protein quality of apheresis derived plasma products treated with riboflavin and UV light and stored at -18°C for up to 1 year. Comparisons were made to paired, untreated controls after 6 months and 1 year of storage. METHODS: This study evaluated the in vitro protein quality of apheresis derived plasma products processed between 8 and 8.5 h from collection and stored at -18°C for 6 months and 1 year. Plasma (205±5 mL) was combined with 35±5 mL of 500 µM riboflavin, and exposed to UV light (6.24 J/mL). A total of 14 plasma units were used for this study. Plasma units were analyzed using standard coagulation assays immediately following treatment, and after 6 months and 1 year of storage at -18°C. RESULTS: Fibrinogen, Total protein, Factors II, VIII, IX, X and XII were modestly affected by storage for 1 year at -18°C. The average percent protein retention in treated plasma samples after 1 year of storage in comparison to controls held under similar conditions were: Total Protein, 103%, Factor II, 88%, Factors VII and XI, 62%, Factor V 60%, Factor VIII and IX, 77%, Fibrinogen, 75%, Factor X, 85% and Factor XII, 82%. CONCLUSION: Results after 6 months (double the EU guidelines recommended storage time) and 1 year (four times longer than the EU guidelines recommended storage time) of storage at -18°C demonstrated that all proteins were well preserved. Values observed for treated products stored under these conditions are within the same range as those reported for other pathogen inactivated plasma products.

Although maternal attachment is an important predictor of infant attachment security and other developmental outcomes, little is known about the formation of maternal attachment in the first few months of the infant's life, particularly among ethnic minority mothers. The current study examined the predictors of postpartum maternal attachment in a sample of 217 Latina women enrolled in a perinatal depression prevention trial. Mothers' attachment to their infants was measured at 6-8 weeks postpartum using the Maternal Postnatal Attachment Scale. A variety of predictors of early attachment were explored including: depressive symptoms during pregnancy, pregnancy intention, feelings about the pregnancy, and the quality of the partner relationship. The strongest predictor of lower maternal attachment was depressive symptoms late in pregnancy; pregnancy intention was marginally predictive of attachment, with lower scores being associated with unwanted pregnancies. The study fills a critical gap in our understanding of the role of depressive symptoms during pregnancy in shaping mothers' early attachment to their infants.

BACKGROUND: The Mirasol pathogen reduction technology system for plasma is based on a riboflavin and UV light treatment process resulting in pathogen inactivation due to irreversible, photochemically induced damage of nucleic acids. The objective of this study was to evaluate the in vitro protein quality of previously frozen FFP, thawed, Mirasol-treated and refrozen for a final storage period of up to 2 years at -30 °C. MATERIALS AND METHODS: All plasma products were held at 4 ± 2 °C, and frozen within 8h after the start of collection. FFP was stored frozen at -30°C for eight time intervals before riboflavin and UV light treatment and refrozen to -30 °C and stored for varying time intervals for a total storage period of up to 2 years at -30 °C. Results were compared to paired, untreated units thawed and stored for the same time intervals. RESULTS: The overall mean values for all time points in riboflavin and UV light treated plasma samples indicates that all proteins were well preserved following a period of frozen storage for 2 years at -30 °C. Factors V, VII and XI, retained 70%, 65% and 53% activity, respectively. All other protein factors, anticoagulant and inhibitor proteins demonstrated retention between 74% and 100%. CONCLUSION: Riboflavin and UV light-treated FFP maintained both coagulant and anticoagulant in vitro protein quality after double freeze/thaw storage at -30 °C for up to 2 years, a finding that may offer processing flexibility to blood centers.
