BACKGROUND: As countries scale up adult voluntary medical male circumcision (VMMC) for HIV prevention, they are looking ahead to long term sustainable strategies, including introduction of early infant male circumcision (EIMC). Although a number of devices for EIMC are prequalified by the World Health Organization, evaluation of additional devices can provide policy-makers and clinicians the information required to make informed decisions. We undertook a field evaluation of the safety and acceptability of the AccuCirc device in Kisumu County, Kenya...

Background: Low birth weight (LBW) infants constitute a vulnerable subset of infants with impaired immunity in early life. In India, there is scarcity of studies that focus on immunization practices in such infants. This analysis aimed to examine immunization practices in LBW infants with the intention to identify areas requiring intervention. Methods: Data on immunization status of LBW infants enrolled in an individually randomized, double-masked, placebo-controlled trial of neonatal vitamin A supplementation were analysed...

Breast milk is the universal preferred nutrition for the newborn human infant. New mother have been encouraged to exclusively breastfeed by health care professionals and consumer-advocacy forums for years, citing "breast milk is the perfect food". The benefits are numerous and include psychological, convenience, economical, ecological and nutritionally superior. Human milk is a composite of nutritional choices of the mother, commencing in the pre-conceptual era. Events influencing the eventual nutritional profile of breast milk for the neonate start with pre-conceptual dietary habits through pregnancy and finally to postpartum...

REVIEW
Heidi E Karpen
Most bone formation and mineralization occurs late in gestation. Accretion of adequate minerals is a key element of this process and is often interrupted through preterm birth. In utero, mineral transport is accomplished via active transport across the placenta and does not require fetal hormone input. Postnatal mineral homeostasis requires a balance of actions of parathyroid hormone, calcitonin, and vitamin D on target organs. Preterm birth, asphyxia, acidosis, and prolonged parenteral nutrition increase the risk of mineral imbalance and metabolic bone disease (MBD)...

BACKGROUND: 1,25-dihydroxyvitamin D (1,25(OH)2D), the biologically active vitamin D metabolite, plays a critical role in calcium and phosphate homeostasis. 1,25(OH)2D is measured to assess calcium and phosphate metabolism, particularly during periods of profound growth and development. Despite its importance, no reliable pediatric reference interval exists, with those available developed using adult populations or out-dated methodologies. Using the fully automated chemiluminescence immunoassay by DiaSorin, we established 1,25(OH)2D pediatric reference intervals using healthy children and adolescents from the CALIPER cohort...

Calcium binding protein calbindin-D28K (CaBP28K) mediates the relationship between vitamin D and calcium, but its mechanism remains unclear during bone formation. The present study reports that maternal CaBP28K levels were positively correlated with paired umbilical cord CaBP28K levels. In addition, CaBP28K levels were positively correlated with the body length, and head and chest circumferences of neonates, but negatively correlated with maternal 25(OH)D3 levels. CaBP28K was also downregulated in MC3T3-E1 osteoblasts when treated with 1,25(OH)2D or VDR overexpression, but was upregulated in the femur of 1α(OH)ase(-/-) mice...

Background: Vitamin A (VA, retinol) supplementation is widely used to reduce child mortality in low-income countries. However, existing research suggests that supplementation with VA alone may not be optimal for infants. Objective: We compared the effect of VA vs. VA combined with retinoic acid (VARA) on retinol uptake and turnover in organs of neonatal rats raised under VA-marginal conditions. Methods: Secondary analysis was conducted on data obtained from two prior kinetic studies of Sprague-Dawley neonatal rats nursed by mothers fed a VA-marginal diet (0...

REVIEW
Christian F Poets, Laila Lorenz
Bronchopulmonary dysplasia (BPD) is one of the most frequent complications in extremely low gestational age neonates, but has remained largely unchanged in rate. We reviewed data on BPD prevention focusing on recent meta-analyses. Interventions with proven effectiveness in reducing BPD include the primary use of non-invasive respiratory support, the application of surfactant without endotracheal ventilation and the use of volume-targeted ventilation in infants requiring endotracheal intubation. Following extubation, synchronised nasal ventilation is more effective than continuous positive airway pressure in reducing BPD...

There is increasing interest to administer ibuprofen as a continuous infusion instead of a traditional bolus for treating Patent Ductus Arteriosus (PDA). However, its compatibility data with commonly used drugs in the neonatal period, including parenteral nutrition (PN) and lipids is unavailable. The aim is to determine the compatibility of intravenous ibuprofen lysine with various ANZNN parenteral nutrition consensus group standard neonatal PN formulations and lipids. The PN and lipid solutions used in a tertiary neonatal unit were obtained...

It is well known that vitamin E and selenium deficiencies in domestic ruminants can lead to white muscle disease. After a clinically normal gestation period at Ouwehand Zoo in the Netherlands, a newborn giraffe ( Giraffa camelopardalis) calf showed clinical signs of white muscle disease almost immediately after birth. The calf was rejected by the mother and was euthanized 3 days later because of deterioration of clinical signs. At necropsy, pulmonary edema and pallor of skeletal and heart muscles was noted...

INTRODUCTION: Pyridoxine-dependent epilepsy (PDE) is a rare disorder of the lysine metabolism, characterized by a pharmacoresistant epileptic encephalopathy that usually begins in the neonatal period. However, its phenotypic spectrum is wide and not limited to seizures. We report a new case of PDE who developed hydrocephalus, along with an exhaustive review of the literature. CASE REPORT: Our patient presented with seizures at 13 h of life. Antiepileptic drugs, vitamins and cofactors were required to achieve seizure control...

BACKGROUND: The toll-like receptor 4 (TLR4) has been reported to play an important role in necrotizing enterocolitis (NEC). As an established regulator of TLR4, vitamin D has been demonstrated to be intestinal-protective. This study aims at finding out whether the vitamin D/vitamin D receptor (VDR) pathway ameliorates NEC by regulating TLR4. METHODS: Serum 25(OH)D was tested and compared in 15 preterm infants with NEC, 12 preterm infants without known complications and 20 healthy term infants...

BACKGROUND: Intramuscular vitamin A supplementation decreases the risk of bronchopulmonary dysplasia (BPD) in very-low-birth-weight preterm infants without significant adverse effects. However, intramuscular vitamin A supplementation is not widely accepted because of the discomfort and risk of trauma associated with repeated injections. Enteral vitamin A supplementation has not been studied adequately in the clinical trials. Enterally administered water-soluble vitamin A is absorbed better than the fat-soluble form...

Vitamin D (VD) has exhibited immunomodulatory role in the pathogenesis of preeclampsia. We hypothesize VD potentiate nifedipine treatment for preeclampsia by shortened the time to control blood pressure and prolong time before subsequent hypertensive crisis. We conduct a randomized trial of 683 primigravid women with preeclampsia, who were assigned to different treatment groups, either nifedipine+placebo or nifedipine+VD orally, by random after screening. Primary endpoints include time to control hypertension and time before another hypertensive crisis...
