There is wide interindividual variation in the efficacy of CD34 + cell mobilization and collection in healthy allogenic hematopoietic stem cell donors. Donor characteristics, blood cell counts, and various factors related to mobilization and collection have been associated with blood CD34 + cell count and CD34 + cell yield after granulocyte colony-stimulating factor (G-CSF) mobilization and collection. Given the heterogenous nature of the literature reporting these associations, in this scoping review we clarify the determinants of CD34 + count and yield. Studies published between 2000 and 2023 reporting allogeneic donors undergoing G-CSF mobilization and peripheral blood stem cell (PBSC) collection were evaluated. Eligible studies were those that assessed blood CD34 + cell count or CD34 + cell yield in the first PBSC collection after mobilization with 4 or 5 days of G-CSF treatment. Associations were recorded between these outcomes and donor factors (age, sex, weight, ethnicity), mobilization factors (G-CSF scheduling or dose), collection factors (venous access, processed blood volume [PBV]) or laboratory factors (blood cell counts at baseline or after mobilization). The 52 studies evaluated between 15 and 20,884 donors. Forty-three studies were retrospective, 33 assessed blood CD34 + cell counts, and 39 assessed CD34 + cell yield from PBSCs. Blood CD34 + cell counts consistently predicted CD34 + cell yield. Younger donors usually had higher blood CD34 + cell counts and CD34 + cell yield. Most studies that investigated the effect of donor ancestry found that donors of non-European ancestry had higher blood CD34 + cell counts after mobilization and higher CD34 + cell yields from collection. The poor consensus about the best predictors of blood CD34 + cell count and yield necessitates further prospective studies, particularly of the role of donor ancestry. The current focus on donor sex as a major predictor requires re-evaluation., (Copyright © 2024 The American Society for Transplantation and Cellular Therapy. Published by Elsevier Inc.

Background: Blood platelets are mediators of atherothrombotic disease and are regulated by complex sets of genes. Association studies in European ancestry populations have already detected informative platelet regulatory loci. Studies in other ancestries can potentially reveal new associations because of different allele frequencies, linkage structures, and variant effects., Objectives: To reveal new regulatory genes for platelet count (PLT)., Methods: Genome-wide association studies (GWAS) were performed in 20,218 Bangladeshi and 9198 Pakistani individuals from the Genes & Health study. Loci significantly associated with PLT underwent fine-mapping to identify candidate genes., Results: Of 1588 significantly associated variants ( P  < 5 × 10 -8 ) at 20 loci in the Bangladeshi analysis, most replicated findings in prior transancestry GWAS and in the Pakistani analysis. However, the Bangladeshi locus defined by rs946528 (chr1:46019890) did not associate with PLT in the Pakistani analysis but was in the same linkage disequilibrium block ( r 2 ≥ 0.5) as PLT-associated variants in prior East Asian GWAS. The single independent association signal was refined to a 95% credible set of 343 variants spanning 8 coding genes. Functional annotation, mapping to megakaryocyte regulatory regions, and colocalization with blood expression quantitative trait loci identified the likely mediator of the PLT phenotype to be PIK3R3 encoding a regulator of phosphoinositol 3-kinase (PI3K)., Conclusion: Abnormal PI3K activity in the vessel wall is already implicated in the pathogenesis of atherothrombosis. Our identification of a new association between PIK3R3 and PLT provides further mechanistic insights into the contribution of the PI3K pathway to platelet biology., (© 2023 The Authors.)

Objective: Women who have direct exposure to incarceration or indirect exposure through their partner are at high risk for poor health behaviors and outcomes, which may have lasting impacts on their children. The objectives of this study were to estimate the prevalence of recent incarceration exposure among women with a recent live birth and assess the relationship between incarceration exposure and maternal and child health., Methods: We used data from the Pregnancy Risk Assessment Monitoring System (36 states and New York City, 2012-2015; N = 146 329) to estimate the prevalence of women reporting that they or their husband/partner spent time in jail during the 12 months before giving birth. We used multivariable logistic regression to assess associations between incarceration exposure and maternal and infant health conditions., Results: The prevalence of incarceration exposure shortly before or during pregnancy was 3.7% (95% CI, 3.6%-3.9%). Women with incarceration exposure had increased odds of prepregnancy hypertension (adjusted odds ratio [aOR] = 1.51; 95% CI, 1.26-1.81), prepregnancy and postpartum depressive symptoms (aOR = 1.95 [95% CI, 1.73-2.19] and 1.49 [95% CI, 1.32-1.67], respectively), and having an infant admitted to the neonatal intensive care unit (aOR = 1.18; 95% CI, 1.04-1.33)., Conclusion: Because a parent's incarceration exposure is an adverse childhood experience with the potential to disrupt important developmental periods and have negative impacts on the socioemotional and health outcomes of children, it is critical for researchers and health care providers to better understand its impact on maternal and infant health. Prenatal and postnatal care may provide opportunities to address incarceration-related health risks.

Introduction: Community-wide initiatives (CWI) to prevent teen pregnancy were implemented in 10 communities in the USA. The CWI supported the implementation of evidence-based teen pregnancy interventions (EBIs) and implementation of best practices for adolescent reproductive health care. Implementation was supported through mobilizing communities, educating stakeholders, and strategies to promote health equity., Methods: We assessed indicators of progress of the CWI for the following five project components (data collected from 2010 to 2015): community mobilization, stakeholder education, working with diverse communities, evidence-based interventions, and increasing access to clinical services and the potential contributions of training and technical assistance., Results: Communities engaged multiple stakeholder groups to contribute to planning, community outreach and education, and partnership development and used multiple dissemination methods to share information on adolescent reproductive health needs and teen pregnancy prevention strategies. The amount of training and technical assistance from state- and community-based organizations was associated with increased numbers of youth receiving EBIs and increased provision of contraceptives. The number of health centers implementing best practices for adolescent reproductive health services increased; conducting sexual health assessments, offering hormonal contraception or IUD, and offering quick start of IUDs were associated with increases in long-acting reversible contraception utilization., Conclusions: These findings demonstrate that scaled prevention efforts can occur with adequate support including training and technical assistance and community awareness and engagement in the process., Policy Implications: The findings raise important questions for understanding what factors contribute to successful community-wide implementation of EBIs and health center best practices for contraceptive access and whether these lead to reductions in teen pregnancies in highly impacted communities., Competing Interests: Conflict of Interest The authors declare no competing interests.

The Centers for Disease Control and Prevention and the American Congress of Obstetricians and Gynecologists recommend universal prenatal HIV testing to prevent perinatal HIV transmission in the U.S.; since the 1990s perinatal HIV transmission has declined. In 2006, 74% of women with a recent live birth reported testing for HIV prenatally or at delivery. We used Pregnancy Risk Assessment Monitoring System data from 36 states and New York City from 2004 to 2013 (N = 387,424) to assess characteristics associated with lack of self-reported testing and state-to-state variability in these associations. Overall, 75.2% (95% confidence interval [CI] 75.0-75.5) of women with a recent live birth reported an HIV test. There were significant differences in testing prevalence by state, ranging from 91.8% (95% CI 91.0-92.6) in New York to 42.3% (95% CI 41.7-43.5) in Utah. In adjusted analysis, characteristics associated with no reported testing included being married, white, non-Hispanic, multiparous, not smoking during pregnancy, and having neither Medicaid nor Special Supplemental Nutritional Program for Women, Infants, and Children. White married women were 57% (adjusted prevalence ratio [aPR] 1.57, 95% CI 1.52-1.63) more likely to report no test compared to white unmarried women. Multiparous married women were 57% (aPR 1.57, 95% CI 1.51-1.64) more likely to report no test compared to multiparous unmarried women. Women who were married, white, non-Hispanic, and multiparous women were 23% less likely to be tested than other women combined. Marital status was significantly associated with lower prevalence of testing in 35 of the 37 reporting areas, and race was significant in 30 of 35 states with race information. The prevalence of reported HIV testing during pregnancy or at delivery remains below 80%. Opportunities exist to increase HIV testing among pregnant women, particularly among certain subpopulations.

Objective: This study aimed to analyze prenatal human immunodeficiency virus (HIV) testing rates over time and describe the impact of state HIV testing laws on prenatal testing., Methods: During 2004-2011, self-reported prenatal HIV testing data for women with live births in 35 states and New York City were collected. Prevalence of testing was estimated overall and by state and year. An annual percent change was calculated in states with at least 6 years of data to analyze testing changes over time. An attorney-coder used WestlawNext to identify states with laws that direct prenatal care providers to screen all pregnant women or direct all women to be tested for HIV and document changes in laws to meet this threshold., Results: The overall prenatal HIV testing rate for 2004 through 2011 combined was 75.7%. State-level data showed a wide range of testing rates (43.2%-92.8%) for 2004 through 2011 combined. In areas with 6 years of data, 4 experienced an annual drop in testing (Alaska, Arkansas, Colorado, and Illinois). States that changed laws to meet the threshold generally had the highest testing rates, averaging 80%, followed by states with a preexisting law, at approximately 70%. States with no law, or no law meeting the threshold, had an average prenatal testing rate of 65%., Conclusions: Prenatal HIV testing remained stable between 2004 and 2011 but remained below universal recommendations. Testing varied widely across states and was generally higher in areas that changed their laws to meet the threshold or had preexisting prenatal HIV testing laws, compared with those with no or limited prenatal HIV testing language.

Introduction: There have been dramatic improvements in reducing infant sleep-related deaths since the 1990s, when recommendations were introduced to place infants on their backs for sleep. However, there are still approximately 3,500 sleep-related deaths among infants each year in the United States, including those from sudden infant death syndrome, accidental suffocation and strangulation in bed, and unknown causes. Unsafe sleep practices, including placing infants in a nonsupine (on side or on stomach) sleep position, bed sharing, and using soft bedding in the sleep environment (e.g., blankets, pillows, and soft objects) are modifiable risk factors for sleep-related infant deaths., Competing Interests: No conflicts of interest were reported.

Objective: We sought to determine the prevalence of postpartum contraceptive use among women with postpartum depressive symptoms (PDS) and examine the association between PDS and contraceptive method., Study Design: We evaluated data from 16,357 postpartum women participating in the 2009-2011 Pregnancy Risk Assessment Monitoring System. PDS was defined as an additive score of ≥10 for three questions on depression, hopelessness, and feeling physically slowed. Contraceptive use was categorized as permanent, long-acting reversible contraception (LARC), user-dependent hormonal, and user-dependent non-hormonal. Logistic regression models compared postpartum contraceptive use and method by PDS status., Results: In total, 12.3% of women with a recent live birth reported PDS. Large percentages of women with (69.4%) and without (76.1%) PDS, used user-dependent or no contraceptive method. There were no associations between PDS and use of any postpartum contraception (adjusted Prevalence Ratio (aPR)=1.00, 95% CI 0.98-1.03) or permanent contraception (aPR=1.05, 95% CI 0.88-1.27). LARC use was elevated, but not significantly, among women with PDS compared to those without (aPR=1.16, 95% CI: 1.00-1.34)., Conclusions: Large percentages of women with and without PDS used user-dependent or no contraception. Since depression may be associated with misuse of user-dependent methods, counseling women about how to use methods more effectively, as well as the effectiveness of non-user dependent methods, may be beneficial., Implications: A large percentage of women with PDS are either not using contraception or using less effective user-dependent methods. Since depression may be associated with misuse of user-dependent contraceptive methods, counseling women about how to use methods more effectively, as well as non-user dependent options, such as LARC, may be beneficial., (Copyright © 2017 Elsevier Inc.

Background and Objectives: To improve hospital to home transitions, a 4-element pediatric patient-centered transition bundle was developed, including: a transition readiness checklist; predischarge teach-back education; timely and complete written handoff to the primary care provider; and a postdischarge phone call. The objective of this study was to demonstrate the feasibility of bundle implementation and report initial outcomes at 4 pilot sites. Outcome measures included postdischarge caregiver ability to teach-back key home management information and 30-day reuse rates., Methods: A multisite, observational time series using multiple planned sequential interventions to implement bundle components with non-technology-supported and technology-supported patients. Data were collected via electronic health record reviews and during postdischarge phone calls. Statistical process control charts were used to assess outcomes., Results: Four pilot sites implemented the bundle between January 2014 and May 2015 for 2601 patients, of whom 1394 had postdischarge telephone encounters. Improvement was noted in the implementation of all bundle elements with the transitions readiness checklist posing the greatest feasibility challenge. Phone contact connection rates were 69%. Caregiver ability to teach-back essential home management information postdischarge improved from 18% to 82%. No improvement was noted in reuse rates, which differed dramatically between technology-supported and non-technology-supported patients., Conclusions: A pediatric care transition bundle was successfully tested and implemented, as demonstrated by improvement in all process measures, as well as caregiver home management skills. Important considerations for successful implementation and evaluation of the discharge bundle include the role of local context, electronic health record integration, and subgroup analysis for technology-supported patients., (Copyright © 2017 by the American Academy of Pediatrics.)

Thrombomodulin-associated coagulopathy (TM-AC) is a newly recognized dominant bleeding disorder in which a p.Cys537Stop variant in the thrombomodulin (TM) gene THBD , results in high plasma TM levels and protein C-mediated suppression of thrombin generation. Thrombin in complex with TM also activates thrombin-activatable fibrinolysis inhibitor (TAFI). However, the effect of the high plasma TM on fibrinolysis in TM-AC is unknown. Plasma from TM-AC cases and high-TM model control samples spiked with recombinant soluble TM showed reduced tissue factor-induced thrombin generation. Lysis of plasma clots from TM-AC cases was significantly delayed compared with controls but was completely restored when TM/thrombin-mediated TAFI activation was inhibited. Clots formed in blood from TM-AC cases had the same viscoelastic strength as controls but also showed a TAFI-dependent delay in fibrinolysis. Delayed fibrinolysis was reproduced in high-TM model plasma and blood samples. Partial restoration of thrombin generation with recombinant activated factor VII or activated prothrombin complex concentrate did not alter the delayed fibrinolysis in high-TM model blood. Our finding of a previously unrecognized fibrinolytic phenotype indicates that bleeding in TM-AC has a complex pathogenesis and highlights the pivotal role of TM as a regulator of hemostasis., (© 2016 by The American Society of Hematology.)

As the prevalence of chronic conditions among women of reproductive age continues to rise, studies assessing the intersection of chronic disease and women's reproductive health status are increasingly needed. However, many data systems collect only limited information on women's reproductive health, thereby hampering the appraisal of risk and protective factors across the life span. One way to expand the study of women's health with minimal investment in time and resources is to integrate questions on reproductive health into existing surveillance systems. In 2013, previously validated questions on women's self-reported reproductive history, use of contraception, and infertility were added to the Behavioral Risk Factor Surveillance System (BRFSS) by seven states (Connecticut, Kentucky, Massachusetts, Mississippi, Ohio, Texas, and Utah); all female respondents aged 18-50 years were included in the pool of respondents for these state-added questions. Of 8691 women who completed the questions, 13.2% reported ever experiencing infertility and 59.8% of those at risk for unintended pregnancy reported using contraception at last intercourse. The information garnered from the state-added reproductive health questions can be augmented with the BRFSS core questions on health-related risk behaviors, chronic conditions, and use of preventive services. Expanding existing data collection systems with supplemental questions on women's reproductive health can provide important information on risk factors and outcomes that may not be available from other sources.

Women's lack of knowledge on symptoms of perinatal depression and treatment resources is a barrier to receiving care. We sought to estimate the prevalence and predictors of discussing depression with a prenatal care provider. We used the 2011 population-based data from 24 sites participating in the Pregnancy Risk Assessment Monitoring System (n = 32,827 women with recent live births) to examine associations between maternal characteristics and report that a prenatal care provider discussed with her what to do if feeling depressed during or after pregnancy. Overall, 71.9 % of women reported discussing perinatal depression with their prenatal care provider (range 60.7 % in New York City to 85.6 % in Maine). Women were more likely to report a discussion on perinatal depression with their provider if they they were 18-29 years of age than over 35 years of age compared to older (adjusted prevalence ratio [aPR] 18 to 19 y = 1.08, 20 to 24 y = 1.10, 25 to 29 y = 1.09), unmarried (aPR = 1.07) compared to married, had <12 years of education (aPR = 1.05) compared to > 12 years, and had no previous live births (aPR = 1.03) compared to ≥ 1 live births. Research is needed on effective ways to educate women about perinatal depression and whether increased knowledge on perinatal depression results in higher rates of treatment and shorter duration of symptoms.
