Objective: About one-third of under-five Filipino children are stunted, with significant socio-economic inequality. This study aims to quantify factors that explain the large gap in stunting between poor and non-poor Filipino children.

Design: Using the 2015 Philippine National Nutrition Survey, we conducted a linear probability model to examine the determinants of child stunting and then an Oaxaca-Blinder decomposition to explain the factors contributing to the gap in stunting between poor and non-poor children.

Setting: Philippines.

Participants: 1881 children aged 6-23 months participated in this study.

Results: The overall stunting prevalence was 38·5 % with a significant gap between poor and non-poor (45·0 % . 32·0 %). Maternal height, education and maternal nutrition status account for 26 %, 18 % and 17 % of stunting inequality, respectively. These are followed by quality of prenatal care (12 %), dietary diversity (12 %) and iron supplementation in children (5 %).

Conclusions: Maternal factors account for more than 50 % of the gap in child stunting in the Philippines. This signifies the critical role of maternal biological and socio-economic circumstances in improving the linear growth of children.

Background: Breast milk is a natural treasure for infants, and its microbiota contains a rich array of bacterial species. When breastfeeding is not possible, infant formula with probiotics can be used as a sole source or as a breast milk supplement. The main aim of this study was to evaluate the growth outcomes and tolerance of infants consuming an infant formula containing Bifidobacterium animalis ssp.

A novel ARCN1 splice-site variant in a Chinese girl with central precocious puberty, intrauterine growth restriction, microcephaly, and microretrognathia.

Department of Endocrinology and Metabolism, Shanghai Children's Medical Center, School of Medicine, Shanghai Jiao Tong University, 1678 Dongfang Road, Shanghai, 200127, China.

The ARCN1 gene encodes the delta subunit of the coatomer protein complex I (COPI), which is essential for mediating protein transport from the Golgi complex to the endoplasmic reticulum. Variants in ARCN1 are associated with clinical features such as microcephaly, microretrognathia, intrauterine growth restriction, short rhizomelic stature, and developmental delays. We present a case of a patient exhibiting intrauterine growth restriction, preterm birth, microcephaly, micrognathia, and central precocious puberty.

Vertebrates differ over 100,000-fold in responses to pro-inflammatory agonists such as bacterial lipopolysaccharide (LPS), complicating use of animal models to study human sepsis or inflammatory disorders. We compared transcriptomes of resting and LPS-exposed blood from six LPS-sensitive species (rabbit, pig, sheep, cow, chimpanzee, human) and four LPS-resilient species (mice, rats, baboon, rhesus), as well as plasma proteomes and lipidomes. Unexpectedly, at baseline, sensitive species already had enhanced expression of LPS-responsive genes relative to resilient species.

Delays in development that occur during early childhood can have long-lasting consequences, potentially leading to poor academic achievement. Research has shown that the human immunodeficiency virus can have neurotropic effects, which may impact the development of the brain in infected children. However, there is a scarcity of evidence regarding developmental delays among children with human immunodeficiency virus in the study area.

Background: Most infants born to women living with HIV (WLH) are HIV-exposed but uninfected exposed infants have poorer growth than HIV-unexposed uninfected children. Few large studies have compared children who are exposed (CHEU) and unexposed (CHUU) in the era of dolutegravir (DTG)-based antiretroviral treatment (ART).

Setting: Longitudinal study of mother-infant CHEU and CHUU pairs in Nairobi and Western Kenya.
