Abstract BACKGROUND A number of social risk factors are reported to increase infant mortality rates and child maltreatment. Public health programs attempt to mitigate risk factors and improve outcomes for infants. This study aimed to explore the association of exposure factors in mothers with infant mortality and maltreatment in Ontario. OBJECTIVES Objectives for this study included: 1. Describe prevalence of infant mortality and maltreatment in Ontario. 2. Explore how maternal risk factors influence infant mortality and maltreatment. DESIGN/METHODS This was a population-based study of 845, 567 infants born between April 1, 2005 and March 31, 2015 using administrative and healthcare databases available at the Institute of Clinical Evaluative Sciences (ICES). Maternal risk factors were selected based on public health home visiting referral criteria. These exposures included, maternal adversity (substance abuse, intimate partner violence, homelessness), newcomer status (new to Canada in past 3 years) and young maternal age (less than 22 years of age). The primary outcome measure was all-cause mortality of infants less than 12 months age. The secondary outcome measures were combined fatal and non-fatal child maltreatment outcomes and were defined using International Classification of Diseases for maltreatment diagnoses. Baseline characteristics and outcomes were described. The association between maternal risk factors and infant mortality and maltreatment was analysed using multivariable logistic modelling, including analysis by type of maternal risk factors and number of risk factors. RESULTS All-cause deaths were present in 0.14% and combined fatal and non-fatal maltreatment outcomes were present in 0.05% of the study population. Young maternal age increased the risk of all-cause mortality 2.4 times (n 171, OR 2.4, 95% CI 2.0–3.0) and maltreatment 6.3 times (n 292, OR 6.3, 95% CI 5.0–7.8). Mental health diagnosis increased the odds of maltreatment by 90% (n 209, OR 1.9, 95% CI 1.5–2.4). Adversity increased the odds of maltreatment by 63% (n 40, OR 1.63, 95% CI 1.0–2.6). The risk of maltreatment also increased as the number of risk factors increased with an OR of 3.5 (95% CI 2.9–4.4) with one risk factor, an OR of 8.2 (95% CI 5.9–11.4) with two risk factors, and an OR of 10.9 (95% CI 5.7 20.7) with three or more risk factors. Newcomer status was not associated with increased risk of maltreatment and mortality. Gestational age showed increasing ORs as prematurity increased. Material deprivation was included as a covariate and was associated with increased risk of maltreatment with increased level of deprivation. CONCLUSION Young maternal age carried the greatest risk of death and maltreatment in infants. There was also an increasing risk of infant mortality and maltreatment with increasing number of risk factors. These findings are important for ensuring public health interventions are targeting the most vulnerable populations with the aim of preventing maltreatment.

Protective Antibodies

Infants born prematurely (before completion of 37 weeks of gestation) are at increased risk of morbidity and mortality due to vaccine preventable diseases, mostly because of their immunological immaturity and failure of transfer of maternal protective antibodies. Despite their great need of being vaccinated, concerns on vaccine safety and efficacy, constitute the main reasons for which vaccinations are often delayed in this group. In this review we summarize the latest evidence on vaccine safety, efficacy and immunogenicity in preterm infants which is similar to full-term infants. Therefore there is no reason for delaying vaccination in this population.

The relation of fetal and placental weight under different conditions was studied by Westermark on a material of 20,000 cases, using mathematical formulas, and he came to the following conclusions: fetal weight is less at first birth than at subsequent birth and is independent of the age of the mother; the placenta of full-term fetuses weighs on average 644.0 in boys and 657.0 in girls; the ratio of placental to fetal weight in boys is 1: 5.47, in girls 1:5.17; fetal weight arrives faster than placenta weight; the number determining the proportion between fetal weight and placenta weight increases with maternal age, but is independent of the number of former pregnancies; it is greater in twins.

Several studies have reported that intestinal microbial colonisation patterns differ between non-allergic and allergic infants. However, the microbial signature underlying the pathogenesis of allergies remains unclear. We aim to gain insight into the development of the intestinal microbiota of healthy infants and infants who develop allergy in early life, and identify potential microbiota biomarkers of later allergic disease. Using a case-control design in a Chinese sub-cohort of a Singaporean birth cohort (GUSTO), we utilised 16S rRNA gene sequencing to assess intestinal microbial composition and diversity of 21 allergic and 18 healthy infants at 3 weeks, 3 months and 6 months of age, and correlated the microbiota with allergy at ages 18 and 36 months. Pronounced differences in intestinal microbiota composition between allergic and healthy infants were observed at 3 months of age. The intestine of healthy infants was colonised with higher abundance of commensal Bifidobacterium. Conversely, Klebsiella, an opportunistic pathogen, was significantly enriched in the allergic infants. Interestingly, infants with a high Klebsiella/Bifidobacterium (K/B) ratio (above the population median K/B ratio) at age 3 months had an odds ratio of developing allergy by 3 years of age of 9.00 (95% confidence interval 1.46-55.50) compared to those with low K/B ratio. This study demonstrated a relationship between the ratio of genera Klebsiella and Bifidobacterium during early infancy and development of paediatric allergy in childhood. Our study postulates that an elevated K/B ratio in early infancy could be a potential indicator of an increased risk of allergy development. This line of research might enable future intervention strategies in early life to prevent or treat allergy. Our study provides new insights into microbial signatures associated with childhood allergy, in particular, suggests that an elevated K/B ratio could be a potential early-life microbiota biomarker of allergic disease.

The Impact

Abstract Background Cleft lip and/or palate (CL/P) is among the most prevalent congenital birth defects. They negatively affect maternal psychological status and may consequently result in higher prevalence of child maltreatment. However, the association of CL/P births with bonding disorders still remains unclear. To address this question, we examined the impact of CL/P birth on mother-to-infant bonding, using the nationwide birth cohort study, Japan Environment and Children's Study. Methods This study was conducted as a nationwide birth cohort study of the Japan environment and children’s study (JECS), an ongoing nationwide birth cohort study in Japan. 104,065 of foetuses in fifteen regional centres in JECS were enrolled. Finally, the participants consisted of 79,140 mother-infant pairs, of which 211 mothers with CL/P infants were included in our analyses. Results First, no increased risk of bonding disorders was observed among all the mothers with CL/P births (odds ratio [95% CI]; 0.97 [0.63-1.48], p = 0.880), and advanced maternal age or multiple parity would adversely affect the associations between bonding disorders and CL/P births, respectively. Thus, after stratification with a combination of maternal age and parity, a significant association of CL/P birth with bonding disorders was found only among advanced-age multiparae (OR [95% CI] = 2.51 [1.17-5.37], p = 0.018), but it was weakened after additional adjustment for maternal depression. Conclusion CL/P birth may increase the risk of bonding disorders among advanced-age multiparae possibly through maternal depression. This finding provides valuable information for the provision of multidisciplinary cleft care.
