Quality of Early Maternal-Child Relationship and Risk of Adolescent Obesity

The quality of the relationship between mother and child affects the child’s neurodevelopment, emotion regulation, and stress response. Extreme or sustained stress responses are associated with dysregulation of physiologic systems involved in energy balance, which could lead to obesity.

The prevalence of obesity in adolescence was more than twice as high among those youth who in early childhood had poor-quality relationships with their mothers compared with those with better relationships. (Read the full article)

Maternal Asthma Medication Use and the Risk of Selected Birth Defects

Asthma is a common obstructive pulmonary disease experienced during pregnancy. Clinical guidelines recommend women with asthma maintain asthma medication use during pregnancy. Epidemiologic studies suggest an association between several types of defects and asthma or asthma medication use during pregnancy.

Data from a large, population-based, multicenter, case-control study was used. This provides the opportunity to study specific birth defects with minimal heterogeneity in case groups, as well as control for a variety of potential confounders. (Read the full article)

Fetal and Maternal Candidate Single Nucleotide Polymorphism Associations With Cerebral Palsy: A Case-Control Study

Candidate genes involved in thrombophilia, inflammation, and preterm birth have previously been associated with cerebral palsy. Most studies to date have included small cohorts, did not allow for multiple testing, and require replication.

This study of children with cerebral palsy and their mothers did not confirm previously reported candidate gene associations. Prothrombin gene mutation was associated with hemiplegia in children born at term to mothers with a reported infection during pregnancy. (Read the full article)

Effect on Infant Illness of Maternal Supplementation With 400 000 IU Vs 200 000 IU of Vitamin A

Postpartum vitamin A supplementation is a strategy to combat vitamin A deficiency and seems to reduce maternal/infant morbidity and mortality. However, controversies exist regarding which dose has a greater efficacy, 200 000 IU (WHO protocol) or 400 000 IU (IVACG protocol).

In this study, postpartum maternal supplementation with 400 000 IU of vitamin A did not provide any additional beneficial effect in reducing infant morbidity compared with the standard dose of 200 000 IU. (Read the full article)

Maternal Metabolic Conditions and Risk for Autism and Other Neurodevelopmental Disorders

Diabetes during pregnancy has been associated with general development impairments in offspring; however, associations between autism and maternal diabetes have been inconsistent. Few studies have examined related conditions accompanied by underlying increased insulin resistance and their association with developmental outcomes.

This population-based study in young children provides evidence that maternal metabolic conditions are a risk factor for autism, developmental delay without autistic symptoms, and impairments in several domains of development, particularly expressive language, after adjusting for sociodemographic and other characteristics.

Maternal Broadly Neutralizing Antibodies Can Select for Neutralization-Resistant, Infant-Transmitted/Founder HIV Variants

ABSTRACT

Each year, >180,000 infants become infected via mother-to-child transmission (MTCT) of HIV despite the availability of effective maternal antiretroviral treatments, underlining the need for a maternal HIV vaccine. We characterized 224 maternal HIV envelope (Env)-specific IgG monoclonal antibodies (MAbs) from seven nontransmitting and transmitting HIV-infected U.S. and Malawian mothers and examined their neutralization activities against nontransmitted autologous circulating viruses and infant-transmitted founder (infant-T/F) viruses. Only a small subset of maternal viruses, 3 of 72 (4%), were weakly neutralized by maternal linear V3 epitope-specific IgG MAbs, whereas 6 out of 6 (100%) infant-T/F viruses were neutralization resistant to these V3-specific IgG MAbs. We also show that maternal-plasma broadly neutralizing antibody (bNAb) responses targeting the V3 glycan supersite in a transmitting woman may have selected for an N332 V3 glycan neutralization-resistant infant-T/F virus. These data have important implications for bNAb-eliciting vaccines and passively administered bNAbs in the setting of MTCT.

IMPORTANCE Efforts to eliminate MTCT of HIV with antiretroviral therapy (ART) have met little success, with >180,000 infant infections each year worldwide. It is therefore likely that additional immunologic strategies that can synergize with ART will be required to eliminate MTCT of HIV. To this end, understanding the role of maternal HIV Env-specific IgG antibodies in the setting of MTCT is crucial. In this study, we found that maternal-plasma broadly neutralizing antibody (bNAb) responses can select for T/F viruses that initiate infection in infants. We propose that clinical trials testing the efficacy of single bNAb specificities should not include HIV-infected pregnant women, as a single bNAb might select for neutralization-resistant infant-T/F viruses.

Embryo integrity regulates maternal proteostasis and stress resilience [Research Papers]

The proteostasis network is regulated by transcellular communication to promote health and fitness in metazoans. In Caenorhabditis elegans, signals from the germline initiate the decline of proteostasis and repression of cell stress responses at reproductive maturity, indicating that commitment to reproduction is detrimental to somatic health. Here we show that proteostasis and stress resilience are also regulated by embryo-to-mother communication in reproductive adults. To identify genes that act directly in the reproductive system to regulate somatic proteostasis, we performed a tissue targeted genetic screen for germline modifiers of polyglutamine aggregation in muscle cells. We found that inhibiting the formation of the extracellular vitelline layer of the fertilized embryo inside the uterus suppresses aggregation, improves stress resilience in an HSF-1-dependent manner, and restores the heat-shock response in the somatic tissues of the parent. This pathway relies on DAF-16/FOXO activation in vulval tissues to maintain stress resilience in the mother, suggesting that the integrity of the embryo is monitored by the vulva to detect damage and initiate an organismal protective response. Our findings reveal a previously undescribed transcellular pathway that links the integrity of the developing progeny to proteostasis regulation in the parent.

How Should Home-Based Maternal and Child Health Records Be Implemented? A Global Framework Analysis

ABSTRACTBackground:A home-based record (HBR) is a health document kept by the patient or their caregivers, rather than by the health care facility. HBRs are used in 163 countries, but they have not been implemented universally or consistently. Effective implementation maximizes both health impacts and cost-effectiveness. We sought to examine this research-to-practice gap and delineate the facilitators and barriers to the effective implementation and use of maternal and child health HBRs especially in low- and middle-income countries (LMICs).Methods:Using a framework analysis approach, we created a framework of implementation categories in advance using subject expert inputs. We collected information through 2 streams. First, we screened 69 gray literature documents, of which 18 were included for analysis. Second, we conducted semi-structured interviews with 12 key informants, each of whom had extensive experience with HBR implementation. We abstracted the relevant data from the documents and interviews into an analytic matrix. The matrix was based on the initial framework and adjusted according to emergent categories from the data.Results:We identified 8 contributors to successful HBR implementation. These include establishing high-level support from the government and ensuring clear communication between all ministries and nongovernmental organizations involved. Choice of appropriate contents within the record was noted as important for alignment with the health system and for end user acceptance, as were the design, its physical durability, and timely redesigns. Logistical considerations, such as covering costs sustainably and arranging printing and distribution, could be potential bottlenecks. Finally, end users' engagement with HBRs depended on how the record was initially introduced to them and how its importance was reinforced over time by those in leadership positions.Conclusions:This framework analysis is the first study to take a more comprehensive and broad approach to the HBR implementation process in LMICs. The findings provide guidance for policy makers, donors, and health care practitioners regarding best implementation practice and effective HBR use, as well as where further research is required.

Relative contribution of maternal adverse childhood experiences to understanding childrens externalizing and internalizing behaviours at age 5: findings from the All Our Families cohort

Background:

The negative effect of adverse childhood experiences (ACEs) on physical and mental health has led to calls for routine screening for ACEs in primary care settings. We aimed to examine the association between maternal ACEs and children’s behaviour problems (externalizing and internalizing) at age 5 in the context of other known predictors.

Methods:

We analyzed data from mother-and-child dyads participating in the All Our Families cohort in Calgary, Canada, between 2011 and 2017. Data were collected for factors related to the individual child (sex, age, temperament and behaviour), the mother (adverse childhood experiences, mental health, personality and parenting) and sociodemographic characteristics (family income, ethnicity and family structure) when the children were 3 and 5 years of age. We used logistic regression models to estimate crude and adjusted associations between maternal ACEs and children’s externalizing (hyperactivity and aggression) and internalizing (anxiety, depression and somatization) behaviours.

Results:

Data were available for 1688 mother-and-child dyads. In the crude models, the presence of 4 or more maternal ACEs was associated with children’s externalizing and internalizing behaviours at age 5. However, these associations were attenuated with adjustment. Persistent maternal mental health symptoms were associated with both externalizing and internalizing behaviours at age 5 (adjusted odds ratio [OR] 4.20, 95% confidence interval [CI] 2.50–7.05, and adjusted OR 2.52, 95% CI 1.66–3.81, respectively). High levels of ineffective parenting behaviours were also associated with both externalizing and internalizing behaviours at age 5 (adjusted OR 6.27, 95% CI 4.30–9.14, and adjusted OR 1.43, 95% CI 1.03–1.99, respectively).

Interpretation:

The association between maternal ACEs and children’s behaviour at age 5 was weakened in the presence of other maternal and family-level factors. Assessments of maternal mental health and parenting behaviours may be better targets for identifying children at risk of behavioural problems.

Maternal Epigenetic Regulation Contributes to Prevention of Estrogen Receptor-negative Mammary Cancer with Broccoli Sprout Consumption

Cruciferous vegetables have been of special interest due to the rich presence of bioactive compounds such as sulforaphane which show promising potential on cancer prevention and therapy as an epigenetic dietary strategy. Abnormal epigenetic alteration as one of the primary contributors to tumor development is closely related to breast cancer initiation and progression. In the present study, we investigated the effect of dietary broccoli sprouts (BSp), a common cruciferous vegetable, on prevention of estrogen receptor (ER)-negative mammary tumors at three different temporal exposure windows using a spontaneous breast cancer mouse model. Our findings indicate that maternal BSp treatment exhibited profound inhibitory and preventive effects on mammary cancer formation in the nontreated mouse offspring. The BSp diet administered to adult mice also showed suppressive effects on mammary cancer but was not as profound as the maternal BSp preventive effects. Moreover, such protective effects were linked with differentially expressed tumor- and epigenetic-related genes, as well as altered global histone acetylation, DNA methylation, and DNA hydroxymethylation levels. We also found that the expression changes of tumor-related genes were associated with the levels of histone methylation of H3K4 and H3K9 in the gene promoter regions. In addition, BSp-enriched sulforaphane was shown to increase protein expression of tumor suppressor genes such as p16 and p53 and inhibit the protein levels of Bmi1, DNA methyltransferases, and histone deacetylases in ERα-negative breast cancer cell lines. Collectively, these results suggest that maternal exposure to key phytochemicals may contribute to ER-negative mammary tumor prevention in their offspring through epigenetic regulations.
