The abundant skin commensal, Staphylococcus epidermidis, is the leading cause of late-onset sepsis (LOS) in preterm infants but rarely causes infections in term infants and adults. Staphylococcal virulence mechanisms and the role of the preterm immune responses in driving these life-threatening infections remain poorly understood.
Patients with congenital heart disease (CHD) are identified in 1% of live births. Improved surgical intervention means many patients now survive to adulthood, the corollary of which is increased mortality in the over-65-year-old congenital heart disease population. In the clinic, genetic sequencing increasingly identifies novel genetic variants in genes related to CHD.
Severe microcephaly, or head circumference at least 3 standard deviations below the mean for age and sex, is a rare condition with diverse etiology, making diagnosis challenging. Following the 2015 to 2016 Zika virus outbreak, surveillance studies in Australia, Canada, New Zealand, and the United Kingdom and Ireland were conducted to monitor severe microcephaly. We describe the etiology, clinical features, and diagnostic investigations of severe microcephaly among children aged younger than 1 year.
Despite growing evidence that parental work–family conflict (WFC) affects children’s emotional well-being, little is known about the multiple pathways underlying such effects. This study examines the association between parental WFC and children’s emotional well-being and the potential mediating role of parenting behaviors in this process.
The capacity for children to self-regulate is an important developmental task of early childhood, with caregivers playing an integral role in self-regulation development. While caregivers' emotions and behaviors are known to impact child self-regulatory capacity, the impact of child self-regulation difficulties on parents is less understood.
The risk of congenital anomalies following first-trimester medication exposure is an important indicator of medication safety during pregnancy. Retrospective cohort studies using routinely collected data are commonly used to assess this risk, yet methodological inconsistencies-such as how cohorts, exposures, timings and outcomes are defined-can compromise reproducibility and validity. This scoping review examined the methodologies used in retrospective cohort studies assessing the association between first-trimester prenatal medication exposure and congenital anomalies.
Autosomal recessive hypophosphatemic rickets type 2 (ARHR2) and generalized arterial calcification of infancy (GACI) occur secondary to biallelic ectonucleotide pyrophosphate/phosphodiesterase 1 (ENPP1) loss-of-function pathogenic variants. GACI is a life-threatening condition, often presenting in the neonatal period with heart failure and hypertension, caused by calcification of the media in large- and medium-sized arteries.
Children's development is dependent on a range of factors influencing their life course outcomes. Protective and challenging social and cultural determinants impact how Indigenous families support their children's developmental foundations. However, there is a lack of international evidence investigating Indigenous child development interventions.
Human milk is a rich source of immunomodulatory factors that influence the development of the infant immune system, including susceptibility to allergic diseases. Among these components, milk antibodies have been extensively studied for their role in protecting against infections; however, their potential contribution to allergy prevention may be equally important. The mechanisms of protection include allergen exclusion, enhanced and targeted antigen presentation, immune modulation via shaping of the infant gut microbiome, and direct regulation of gut immune responses.
