RESUMO

Decoding the gene regulatory mechanisms mediating self-renewal of hematopoietic stem cells (HSCs) during their amplification in the fetal liver (FL) is relevant for advancing therapeutic applications aiming to expand transplantable HSCs, a long-standing challenge. Here, to explore intrinsic and extrinsic regulation of self-renewal in FL-HSCs at the single cell level, we engineered a culture platform designed to recapitulate the FL endothelial niche, which supports the amplification of serially engraftable HSCs ex vivo. Leveraging this platform in combination with single cell index flow cytometry, serial transplantation assays, and single cell RNA-sequencing, we elucidated previously unrecognized heterogeneity in immunophenotypically defined FL-HSCs and demonstrated that differentiation latency and transcriptional signatures of biosynthetic dormancy are distinguishing properties of self-renewing FL-HSCs with capacity for serial, long-term multilineage hematopoietic reconstitution. Altogether, our findings provide key insights into HSC expansion and generate a novel resource for future exploration of the intrinsic and niche-derived signaling pathways that support FL-HSC self-renewal.

RESUMO

Contemporary data on infections after intensive chemotherapy for acute myeloid leukemia (AML) are scarce. Cladribine, high-dose cytarabine, G-CSF, and dose-escalated mitoxantrone ("CLAG-M") may result in higher remission rates than standard-dose cytarabine plus anthracycline ("7 + 3") but may result in more infections. We compared moderate to severe infections occurring up to 90 days after the first induction cycle for AML or other high-grade myeloid neoplasms in patients receiving CLAG-M for newly diagnosed (n = 196) or relapsed/refractory disease (n = 131) or 7 + 3 for newly diagnosed disease (n = 115). For newly diagnosed disease, microbiologically documented infections were more frequent after CLAG-M compared to 7 + 3 (adjusted rate ratio, 1.65 [95% CI, 1.06-2.58]; P = 0.03), with a cumulative incidence of 27.8% and 16.5% by day 90, respectively. Patients receiving CLAG-M for relapsed/refractory disease had the highest cumulative incidence of 50.7%. Bacterial bloodstream infections were the most frequent followed by respiratory tract infections. Among 29 patients (7%) who died, infection was a primary or contributing cause of death in 59%. These data indicate that infections continue to cause substantial morbidity in patients treated for AML, especially those treated for relapsed/refractory disease, and are more common with newer, more myelosuppressive regimens such as CLAG-M. Improved strategies for infection prevention are needed.

RESUMO

Women experience anxiety, depression, and stress at higher levels than men and have more parenting responsibilities, especially establishing health practices in the home. Given children's vulnerability, this study aimed to increase understanding of how mothers' mental health status relates to maternal weight-related cognitions, home food environments, and child health via a cross-sectional survey design. In a cluster analysis, using maternal anxiety, depression, and stress assessments, we placed the sample of 531 mothers of school-age children into four clusters: Cluster 1 had the best mental health status, Cluster 2 had high stress, Cluster 3 had anxiety and moderate stress, and Cluster 4 had anxiety, depression, and high stress. Our results indicate an overall downward trend in weight-related cognitions as mental health worsened. Similarly, as mental health declined, so did home food environment characteristics, such as the greater use of non-recommended child feeding practices, fewer family meals, and greater sugar-sweetened beverage supplies. As mothers' mental health status became poorer, children's general health and mental health quality of life declined, and sugar-sweetened beverage intake increased. Our findings suggest that maternal stress, anxiety, and depression are moderately to strongly linked with mothers' cognitions, home food environments, and children's health. Our results also suggest that mental health interventions for mothers should assess cognitions and home food environments and consider the extent to which these factors are affecting family health.

RESUMO

PURPOSE OF REVIEW: The purpose of this review is to primarily discuss the unwarranted decline in the use of umbilical cord blood (UCB) as a source of donor hematopoietic stem cells (HSC) for hematopoietic cell transplantation (HCT) and the resulting important implications in addressing healthcare inequities, and secondly to highlight the incredible potential of UCB and related birthing tissues for the development of a broad range of therapies to treat human disease including but not limited to oncology, neurologic, cardiac, orthopedic and immunologic conditions. RECENT FINDINGS: When current best practices are followed, unrelated donor umbilical cord blood transplant (CBT) can provide superior quality of life-related survival compared to other allogeneic HSC donor sources (sibling, matched or mismatched unrelated, and haploidentical) through decreased risks of relapse and chronic graft vs. host disease. Current best practices include improved UCB donor selection criteria with consideration of higher resolution human leukocyte antigen (HLA) typing and CD34+ cell dose, availability of newer myeloablative but reduced toxicity conditioning regimens, and rigorous supportive care in the early posttransplant period with monitoring for known complications, especially related to viral and other infections that may require intervention. Emerging best practice may include the use of ex vivo expanded single-unit CBT rather than double-unit CBT (dCBT) or 'haplo-cord' transplant, and the incorporation of posttransplant cyclophosphamide as with haploidentical transplant and/or incorporation of novel posttransplant therapies to reduce the risk of relapse, such as NK cell adoptive transfer. Novel, non-HCT uses of UCB and birthing tissue include the production of UCB-derived immune effector cell therapies such as unmodified NK cells, chimeric antigen receptor-natural killer cells and immune T-cell populations, the isolation of mesenchymal stem cells for immune modulatory treatments and derivation of induced pluripotent stem cells haplobanks for regenerative medicine development and population studies to facilitate exploration of drug development through functional genomics. SUMMARY: The potential of allogeneic UCB for HCT and novel cell-based therapies is undervalued and underutilized. The inventory of high-quality UCB units available from public cord blood banks (CBB) should be expanding rather than contracting in order to address ongoing healthcare inequities and to maintain a valuable source of cellular starting material for cell and gene therapies and regenerative medicine approaches. The expertise in Good Manufacturing Practice-grade manufacturing provided by CBB should be supported to effectively partner with groups developing UCB for novel cell-based therapies.

RESUMO

Families are a key provider of support that may encourage positive weight-related behaviors. Yet little is known about the relation of family support to children's performance of weight-related behaviors. Mothers (N = 524) who completed an online survey were categorized as having low, moderate, or high family support for fruit/vegetable intake, breakfast intake, limiting sugar-sweetened beverage intake, physical activity, limiting sedentary screentime, and sleep. ANOVA revealed that children in families with high support for breakfast ate this meal significantly more often. Additionally, children in families with low support for limiting sugar-sweetened beverages had significantly greater intake. Surprisingly, families with moderate support for physical activity and sleep tended to have children with lower physical activity level, sleep duration, and sleep quality, and fewer days/week with set bedtimes than those with low and high support. Binomial logistic regression revealed that high family support for eating breakfast, limiting sugar-sweetened beverages, and getting sufficient sleep had greater odds of meeting recommendations for these behaviors. Findings suggest that greater family support for healthy weight-related behaviors tends to be associated with children's performance of these behaviors. Future interventions should further examine the impact of different types of family support on weight-related behaviors to better understand this complex interplay.

RESUMO

BACKGROUND: Parents are children's primary role models, are food and physical activity gatekeepers, and create the home structure/lifestyle environment. Thus, parents strongly influence children's weight-related behaviors and have the opportunity to cultivate a "culture of health" within the home. Yet, there is a dearth of evidence-based obesity prevention intervention programs, especially for families with children aged 6-11 years, commonly called middle childhood. METHODS: The aim of the HomeStyles-2 online learning mode RCT is to determine whether this novel, age-appropriate, family intervention enables and motivates parents to shape home environments and weight-related lifestyle practices (i.e.,diet, exercise, sleep) to be more supportive of optimal health and reduced obesity risk in middle childhood youth more than those in the control condition. The RCT will include the experimental group and an attention control group. The participants will be parents with school-age children who are systematically randomly assigned by computer to study condition. The HomeStyles intervention is predicated on the social cognitive theory and a social ecological framework. The RCT will collect sociodemographic characteristics of the participant, child, and partner/spouse; child and parent health status; parent weight-related cognitions; weight-related behaviors of the parent and child; and weight-related characteristics of the home environment. Deliverables Enrollment for this study will begin in 2022. DISCUSSION: This paper describes these aspects of the HomeStyles-2 intervention: rationale; sample eligibility criteria and recruitment; study design; experimental group intervention theoretical and philosophical underpinnings, structure, content, and development process; attention control intervention; survey instrument development and components; outcome measures; and planned analyses.

RESUMO

Cytomegalovirus (CMV)-seropositive umbilical cord blood transplantation (CBT) recipients have a high incidence of CMV-associated complications. There are limited data regarding the efficacy of letermovir for preventing clinically significant CMV infection (CS-CMVi), and the impact of letermovir prophylaxis on delayed-onset CMV reactivation after letermovir discontinuation, in CBT recipients. We compared the cumulative incidence of CS-CMVi and CMV detection in 21 CMV-seropositive CBT recipients receiving letermovir prophylaxis with a historical cohort of 40 CBT recipients receiving high-dose valacyclovir prophylaxis. Letermovir was administered on day +1 up to day +98. The cumulative incidence of CS-CMVi was significantly lower by day 98 in the letermovir cohort (19% vs 65%). This difference was lost by 1 year due to a higher incidence of delayed-onset CMV reactivation in the letermovir cohort. No patients developed CMV disease in the letermovir cohort within the first 98 days compared with 2 cases (2.4%) in the high-dose valacyclovir cohort; 2 patients developed CMV enteritis after discontinuing letermovir. Median viral loads were similar in both cohorts. Thus, letermovir is effective at preventing CS-CMVi after CBT, but frequent delayed-onset infections after letermovir discontinuation mandate close monitoring and consideration for extended prophylaxis.

RESUMO

Family social capital includes the social relationships, values, and norms shared by a family and is positively linked with children's mental and physical health status. This cross-sectional study addresses a gap in the literature related to family social capital vis-à-vis weight-related behaviors and home environments of 557 mothers and their young children (ages 2 to 9 years). Mothers completed an online survey comprised of valid, reliable questionnaires assessing family relationships and weight-related behavioral and home environment measures. The measures that determined family social capital (i.e., supportive, engaged parenting behaviors; family cohesion; family conflict; and family meal frequency) yielded distinct tertile groups that differed significantly (p < 0.001) on every family social capital measure with large effect sizes. Analysis of variance with Tukey post-hoc test revealed greater family social capital was linked to significantly better maternal health, dietary intake, physical activity, and sleep behavior. Additionally, maternal modeling of healthy eating and physical activity, child feeding practices, and home environments was higher in groups with greater family social capital. Child mental and physical health, physical activity, and sleep quality were better in families with greater family social capital. Findings suggest greater family social capital is linked to healthier weight-related behaviors and home environments. Future intervention studies should incorporate strategies to build family social capital and compare longitudinal outcomes to traditional interventions to determine the relative value of family social capital on health behaviors.

RESUMO

Hispanic mothers and children in the United States experience a high prevalence of obesity, which may be affected by maternal acculturation level. Little is known about the association of acculturation on weight-related behaviors. This study describes differences in weight-related behaviors by acculturation level of Hispanic mothers residing in the U.S. and compares them to behaviors of White mothers. Acculturation level was determined using personal acculturation and acculturation environment variables. Cluster analysis of acculturation variables identified three groups of Hispanic mothers: low personal and environmental acculturation (n = 46), high personal and low environmental acculturation (n = 65), and high personal and environmental acculturation (n = 38). Results indicate that, compared to White mothers (n = 340), the least acculturated cluster of Hispanic mothers tended to model physical activity less often and the most acculturated exerted more pressure on children to eat. Mothers in the least acculturated cluster tended to rate children's health status lower, indicate that children had greater fruit juice and less milk intakes, have more meals in locations associated with less healthy meals, and have the least space and supports for physical activity. Findings highlight relationships between maternal acculturation level and weight-related behaviors and suggest strategies for helping acculturating Hispanic mothers create healthier lifestyles and home environments.

RESUMO

OBJECTIVES: Adequate dietary consumption of long chain omega-3 fatty acids (n-3 LCPUFA) during pregnancy has been associated with better maternal and infant health outcomes. Given that the primary source of n-3 LCPUFA is fish and fish oils, concerns surrounding contamination and uncertainty of safe fish intake guidelines have negatively affected consumption of fish during pregnancy. Although obstetric healthcare providers are in a unique position to influence dietary intake patterns, a gap exists in their understanding the knowledge and practices surrounding n-3 LCPUFA. This needs assessment investigation evaluated knowledge, attitudes and prescribing/recommending practices of obstetric practitioners surrounding n-3 LCPUFA consumption and/or supplementation to generate evidence supporting the development of targeted educational initiatives. METHODS: A cross-sectional, needs assessment was conducted using anonymous online-survey of affiliate members of the American College of Nurse Midwives (N = 105). A 24-item, previously validated (α = 0.86) needs assessment survey (Obstetric Clinicians Omega-3 Survey, OCOS) was used to assess attitudes, knowledge, and prescribing practices surrounding n-3 LCPUFA. RESULTS: The total OCOS score representing attitudes, knowledge and prescribing patterns collectively was 69.48% (Mean = 79.90(± 12.44), score range = 24-115). Scores for the sub-domains included attitude 68.33% (Mean = 20.50(± 3.64), score range = 6-30); knowledge 71.40% (Mean = 30.70(± 5.43), score range = 9-43); and prescribing patterns 68.31% (Mean = 28.69(± 5.39), score range = 9-42). CONCLUSIONS FOR PRACTICE: Although the majority of respondents had fair-moderate n-3 LCPUFA knowledge, attitudes and prescribing/recommending, our results highlight an opportunity for additional research and educational outreach targeting improved n-3 LCPUFA knowledge and practices. Specific areas of educational interest included associated health outcomes, dosing and safe consumption guidelines.

RESUMO

BACKGROUND: Cord blood transplant (CBT) recipients have a high incidence of herpes zoster (HZ) in the context of short-term peritransplant antiviral prophylaxis. In 2009, international guidelines recommended HZ prophylaxis for at least 1 year after hematopoietic cell transplant. The impact of longer-term antiviral prophylaxis on HZ incidence after CBT is unknown. METHODS: We retrospectively analyzed varicella zoster virus (VZV)-seropositive CBT recipients who were transplanted between 2006 and 2016. We abstracted HZ events and other variables for up to 5 years post-CBT. We calculated the cumulative incidence of HZ and used Cox proportional hazards regression to identify variables associated with HZ. RESULTS: The study cohort consisted of 227 patients. Among 1-year survivors, 91% were still receiving prophylaxis, for a median duration of 20.6 months. HZ occurred in 44 patients (19%) at a median of 23.6 months. The cumulative incidence of HZ by 1 year after CBT was 1.8% (95% confidence interval [CI], .1%-4%), but increased to 26% (95% CI, 19%-33%) by 5 years. In a multivariable analysis, acute graft-vs-host disease was associated with increased risk, whereas antiviral prophylaxis was associated with reduced risk for HZ (adjusted hazard ratio, 0.19 [95% CI, .09-.4]). There was no association between CD4+ T-cell counts at 1 year post-CBT and subsequent risk for HZ. CONCLUSIONS: We found a high incidence of HZ after CBT despite antiviral prophylaxis for > 1 year. Based on these findings, we suggest longer duration of prophylaxis for HZ after CBT. Compliance with antiviral prophylaxis, VZV-specific immune monitoring, and vaccination to mitigate HZ after CBT also require further study.

RESUMO

Cord blood transplantation (CBT) is associated with low risk of leukemia relapse. Mechanisms underlying antileukemia benefit of CBT are not well understood, however a previous study strongly but indirectly implicated cells from the mother of the cord blood (CB) donor. A fetus acquires a small number of maternal cells referred to as maternal microchimerism (MMc) and MMc is sometimes detectable in CB. From a series of 95 patients who underwent double or single CBT at our center, we obtained or generated HLA-genotyping of CB mothers in 68. We employed a technique of highly sensitive HLA-specific quantitative-PCR assays targeting polymorphisms unique to the CB mother to assay CB-MMc in patients post-CBT. After additional exclusion criteria, CB-MMc was evaluated at multiple timepoints in 36 patients (529 specimens). CB-MMc was present in seven (19.4%) patients in bone marrow, peripheral blood, innate and adaptive immune cell subsets, and was detected up to 1-year post-CBT. Statistical trends to lower relapse, mortality, and treatment failure were observed for patients with vs. without CB-MMc post-CBT. Our study provides proof-of-concept that maternal cells of the CB graft can be tracked in recipients post-CBT, and underscore the importance of further investigating CB-MMc in sustained remission from leukemia following CBT.

RESUMO

This cross-sectional study compared weight-related cognitions, behaviors, and home environments of 568 mothers of young children (ages 2 to <9 years) by racial/ethnic group. Maternal health status was good and did not differ by race/ethnicity. Mothers were somewhat confident in their ability to promote healthy physical activity and eating behaviors in their children, with White and Asian mothers having greater confidence than Hispanic mothers. Mothers had low physical activity, with Hispanic mothers getting more sedentary screentime than White and Asian mothers. Mothers' dietary intake did not differ. Modeling of healthful behaviors was more frequent in White than Hispanic mothers. Asian mothers tended to use non-recommended feeding patterns more than White, Hispanic, and Black mothers. Children's physical activity and screentime did not differ by race/ethnicity. Asian children tended to drink less sugar-sweetened beverages and more milk than counterparts. All reported frequent family meals, with Hispanic mothers reporting more family meals eaten in less healthful locations. Household food environments did not differ. However, White mothers reported greater access to physical activity space and supports than Hispanic mothers. Race/ethnicity may link with maternal weight-related cognitions, behaviors, and home environments and thus can help inform the development of interventions tailored by race/ethnicity.

RESUMO

Although the use of treosulfan (TREO) in conventional donor hematopoietic cell transplantation (HCT) has been extensively evaluated, its use in cord blood transplantation (CBT) for hematologic malignancies has not been reported. Between March 2009 and October 2019, 130 CBT recipients were enrolled in this prospective multicenter phase 2 study. The conditioning regimen consisted of TREO, fludarabine, and a single fraction of 2 Gy total-body irradiation. Cyclosporine and mycophenolate mofetil were used for graft-versus-host disease prophylaxis. The primary end point was incidence of graft failure (GF), and based on risk of GF, patients were classified as low risk (arm 1, n = 66) and high risk (arm 2, n = 64). The median age was 45 years (range, 0.6-65 years). Disease status included acute leukemias in first complete remission (CR; n = 56), in ≥2 CRs (n = 46), and myelodysplastic (n = 25) and myeloproliferative syndromes (n = 3). Thirty-five patients (27%) had received a prior HCT. One hundred twenty-three patients (95%) engrafted, with neutrophil recovery occurring at a median of 19 days for patients on arm 1 and 20 days for patients on arm 2. The 3-year overall survival, relapse-free survival (RFS), transplant-related mortality, and relapse for the combined groups were 66%, 57%, 18%, and 24%, respectively. Among patients who had a prior HCT, RFS at 3 years was 48%. No significant differences in clinical outcomes were seen between the 2 arms. Our results demonstrate that TREO-based conditioning for CBT recipients is safe and effective in promoting CB engraftment with favorable clinical outcomes. This trial was registered at www.clinicaltrials.gov as #NCT00796068.

RESUMO

OBJECTIVE: To explore parenting advice children would provide to help parents encourage positive health-related behaviors by children. DESIGN: Focus group discussions were conducted, and children shared the advice they would provide parents to help them encourage healthy weight-related behaviors (ie, diet, physical activity, and sleep) for children. SETTING: Focus groups (n = 65) were conducted in 3 states (Florida, New Jersey, and West Virginia). PARTICIPANTS: School-age children (n = 194) between the ages of 6 and 11 years old. PHENOMENON OF INTEREST: What parenting practices are recommended by children, and are they in line with best-practice guidelines? ANALYSIS: Focus group data were analyzed to identify themes and trends. RESULTS: Children's recommendations were congruent with authoritative parenting styles (ie, high levels of warmth and control). Most of the advice shared by children aligned with recommended parent practices (ie, responsive feeding, facilitation, environmental restructuring, parent modeling, and encouragement). However, not all of the children's advice aligned with best practices guidelines (ie, use of food rewards and deception). CONCLUSIONS AND IMPLICATIONS: Future nutrition education programs may be strengthened by helping parents adopt best practices for promoting healthy child behaviors. Furthermore, teaching children about recommended child feeding parenting practices may help protect future generations by preparing children to care for younger siblings or raise their children using best parenting practices.

RESUMO

BACKGROUND: Over 50% of patients with heart failure (HF) report suffering from pain and pain-related burdens; however, pain in HF patients has not been recognized or well treated. Few studies have comprehensively examined pain management in patients with HF from nurses' perception. AIMS: To investigate nurses' perception of pain management in HF patients. METHODS: Members of American Association of Heart Failure Nurses (AAHFN) were invited to participate in a cross-sectional online survey. RESULTS: A total of 147 nurses responded and completed the survey. The majority agreed that pain in HF patients was related to anxiety, depression, fatigue, and unplanned hospitalization, and that pain should be individually assessed and managed. More than 80% thought pain management practice in HF patients should be improved, and 78.1% were interested in getting more information and believed an online education module was the most preferable approach. Lack of pain assessment tools, drug addiction, side effect, overuse, underuse, and contraindication with other medications were the main concerns regarding opioid use in pain management in HF. The gaps in pain management in HF patients included lack of knowledge of opioid use, lack of consideration and awareness of pain, no clinical guidelines for pain assessment and treatment, and complicated pain management with multiple chronic conditions. CONCLUSIONS: The impact of pain and need for individual assessment and management of pain in HF patients were perceived by nurses; improvement in pain management practice in HF patients is needed. Concerns regarding opioid use and gaps in pain management of HF patients should be addressed.

RESUMO

The purpose of this study was to examine metaphors used by patients with chronic conditions to describe their experience with holistic nurse coaching. A secondary analysis was conducted using Metaphor Identification Procedure to analyze the corpus of 112 pages of typed transcription. Five metaphors emerged: (1) taking personal power back like acquiring a new toolbox; (2) seeing health challenges from different angles like a duck pond race; (3) shifting perception of a chronic condition like a spider turned into a friend; (4) engaging in self-care like caring for a favorite plant; and (5) choosing to focus on the positive like a collage that changed from dark to light. Specific interventions can be developed to address each of these metaphors to help patients live well with chronic conditions.

RESUMO

Umbilical cord blood (UCB) transplantation (UCBT) is a curative procedure for patients with hematologic malignancies and genetic disorders and expands access to transplantation for non-Caucasian patients unable to find a fully matched unrelated donor. In 2011, the US Food and Drug Administration required that unrelated UCBT be performed using either licensed UCB or unlicensed UCB under the Investigational New Drug (IND) program. The National Marrow Donor Program manages an IND under which 2456 patients (1499 adults and 957 children, 564 with malignant diseases and 393 with nonmalignant diseases) underwent single or double UCBT between October 2011 and December 2016. The median patient age was 31 years (range, <1 to 81 years), and 50% of children and 36% of adults were non-Caucasian. The median time to neutrophil engraftment (ie, absolute neutrophil count ≥500/mm3) was 22 days for adults, 20 days for pediatric patients with malignant diseases, and 19 days for pediatric patients with nonmalignant diseases, with corresponding rates of engraftment at 42 days of 89%, 88%, and 90%. In these 3 groups of patients, the incidence of acute graft-versus-host disease (GVHD) grade II-IV was 35%, 32%, and 24%; the incidence of chronic GVHD was 24%, 26%, and 24%; and 1-year overall survival (OS) was 57%, 71%, and 79%, respectively. In multivariate analysis, younger age, lower Hematopoietic Cell Transplantation-Specific Comorbidity Index, early-stage chemotherapy-sensitive disease, and higher performance score were predictive of improved OS for adults. In a subset analysis of children with malignancies undergoing single UCBT, the use of either licensed UCB (n = 48) or unlicensed UCB (n = 382) was associated with similar engraftment and survival. The use of unlicensed UCB units is safe and effective and provides an important graft source for a diverse population.

RESUMO

This study explored the differences in weight-related characteristics when socioeconomic status (SES) was assessed by economic, cultural, social, and environmental-health capital individually and as a composite with the goal of determining the stability of differences across types of capital and to ascertain whether single or a combination of capital indicators of SES should be used in nutrition and public health studies. Mothers (n = 557) of young children completed a survey assessing capital and weight-related characteristics. Mothers with higher economic, cultural, and social capital and composite SES had fewer sugar-sweetened beverage servings, fewer meals in front of the TV, more food security, and greater neighborhood space/supports for physical activity than comparators. Few differences occurred among environmental-health capital groups. Composite SES performed similarly to individual economic, cultural, and social capital measures. Findings suggest single SES indicators may be sufficiently stable to capture differences in weight-related characteristics. Each capital type captures a unique aspect of SES; thus, assessing an array of capital types could advance understanding of SES aspects on weight-related characteristics.
