Congenital Diaphragmatic hernia (CDH) is a condition characterized by a defect in the diaphragm leading to protrusion of abdominal contents into the thoracic cavity interfering with normal development of the lungs. The defect may range from a small aperture in the posterior muscle rim to complete absence of diaphragm. The pathophysiology of CDH is a combination of lung hypoplasia and immaturity associated with persistent pulmonary hypertension of newborn (PPHN) and cardiac dysfunction. Prenatal assessment of lung to head ratio (LHR) and position of the liver by ultrasound are used to diagnose and predict outcomes...

Birth asphyxia also termed perinatal asphyxia is an obstetric complication that strongly affects brain structure and function. Central nervous system is highly susceptible to oxidative damage caused by perinatal asphyxia while activation and maturity of the proper pathways are relevant to avoiding abnormal neural development. Perinatal asphyxia is associated with high morbimortality in term and preterm neonates. Although several studies have demonstrated a variety of biochemical and molecular pathways involved in perinatal asphyxia physiopathology, little is known about the synaptic alterations induced by perinatal asphyxia...

BACKGROUND: Reduction of neonatal and under-five mortality rates remains a primary target in the achievement of universal health goals, as evident in renewed investments of Sustainable Development Goals. Various studies attribute declines in mortality to the combined effects of improvements in health care practices and changes in socio-economic factors. Since the early nineties, Cambodia has managed to evolve from a country devastated by war to a nation soon to enter the group of middle income countries...

This study aimed to investigate the neurotoxicity of exosomes to cultured neuroblastoma and neurons in vitro and to mature and newborn neurons in the hippocampus in vivo. Recent in vitro and in vivo studies have shown that exosomes, small membranous vesicles secreted from many cell types, contain pathogenic proteins including full-length amyloid precursor protein (flAPP) and amyloid precursor protein (APP) metabolites. However, the function of these exosomes in Alzheimer disease (AD) has not been much explored...

BACKGROUND: Retinopathy of prematurity (ROP) is a vaso-proliferative disease of the eye, which mainly affects preterm newborn infants with an incompletely vascularized retina. The incidence of ROP has increased in industrialized countries due to the increased survival of extremely low birth weight (ELBW) infants. ROP is also increasing in developing countries like Indonesia, where it is most likely due to the improved survival of ELBW infants. OBJECTIVE: To ascertain the incidence of ROP and possible risk factors associated with the development of ROP in preterm infants in Indonesia...

Steroid 21-hydroxylase deficiency is the most prevalent form of congenital adrenal hyperplasia (CAH), accounting for approximately 95% of cases. With the advent of newborn screening and hormone replacement therapy, most children with CAH survive into adulthood. Adolescents and adults with CAH experience a number of complications, including short stature, obesity, infertility, tumor, osteoporosis, and reduced quality of life. Transition from pediatric to adult care and management of long-term complications are challenging for both patients and health-care providers...

OBJECTIVES: Outcome prediction for pediatric heart surgery has focused on mortality but mortality has been significantly reduced over the past 2 decades. Clinical care practices now emphasize reducing morbidity. Physiology-based profiles assessed by the Pediatric Risk of Mortality (PRISM) score are associated with new significant functional morbidity detected at hospital discharge. Our aims were to assess the relationship between new functional morbidity and surgical risk categories (Risk Adjustment for Congenital Heart Surgery [RACHS] and Society for Thoracic Surgery Congenital Heart Surgery Database Mortality Risk [STAT]), measure the performance of 3-level (intact survival, survival with new functional morbidity, or death) and 2-level (survival or death) PRISM prediction algorithms, and assess whether including RACHS or STAT complexity categories improves the PRISM predictive performance...

Birth weight and placental weight are crucial parameters for the survival of fetuses and newborns in mammals. High variation in the MHC is important for an effective adaptive immune response. The maternal immune system must be controlled in relation to the semi-allogenic fetus. The immunoregulatory HLA/MHC class Ib gene, HLA-G, is strongly expressed on extravillous trophoblast cells. We investigated birth weight and placental weight of the newborns in mothers heterozygous for an HLA-G 14bp insertion (Ins)/deletion (Del) gene polymorphism...

Post-natal hippocampal neurogenesis plays a role in hippocampal function, and neurons born post-natally participate to spatial memory and mood control. However, a great proportion of granule neurons generated in the post-natal hippocampus are eliminated during the first 3 weeks of their maturation, a mechanism that depends on their synaptic integration. In a recent study, we examined the possibility of enhancing the synaptic integration of neurons born post-natally, by specifically overexpressing synaptic cell adhesion molecules in these cells...

Renal medullary carcinoma (RMC) is a rare but highly aggressive neoplasm that primarily affects young African Americans with sickle cell trait. Most patients present with macroscopic hematuria and have metastases at diagnosis. Chemotherapy, biologics directed against the more common renal cell carcinomas and radiation have all shown limited efficacy in treating patients with advanced RMC. We report two patients with RMC. Both had Stage IV disease. One underwent radical nephrectomy followed by radiation and biologic drug therapy but died five months later; the other underwent multiple cycles of chemotherapy plus anti-angiogenesis treatment but died 15 months after diagnosis...

BACKGROUND: Health system strengthening is crucial to improving infant and child health outcomes in low-resource countries. While the knowledge related to improving newborn and child survival has advanced remarkably over the past few decades, many healthcare systems in such settings remain unable to effectively deliver pediatric advance life support management. With the introduction of the Emergency Triage, Assessment and Treatment plus Admission care (ETAT+)-a locally adapted pediatric advanced life support management program-in Rwandan district hospitals, we undertook this study to assess the extent to which these hospitals are prepared to provide this pediatric advanced life support management...

All aging individuals will develop some degree of decline in cognitive capacity as time progresses. The molecular and cellular mechanisms leading to age-related cognitive decline are still not fully understood. Through our previous research, we discovered that active neural progenitor cells selectively become more quiescent in response to aging, thus leading to the decline of neurogenesis in the aged hippocampus. Here, we further find that aging impaired dendrite development of newborn neurons. Currently, no effective approach is available to increase neurogenesis or promote dendrite development of newborn neurons in the aging brain...

The number of active ribosomal genes (AcRG) was evaluated in 172 carriers of chromosomal abnormalities (CA) such as Down's syndrome (DS), Robertsonian translocations (RT), Klinefelter's and Turner's syndromes, trisomy Х, disomy Y, and various structural CA. In controls (n=318), AcRG dosage varied from 119 to 190 copies with a mean of 151 copies per diploid genome. In CA carriers, except for DS newborns, AcRG dosage was not beyond these limits. As shown previously, only within these limits cellular homeostasis and organism's viability can be supported, while genomes beyond these limits are eliminated by embryonic loss...

The study of medications among pediatric patients has increased worldwide since 1997 in response to new legislation and regulations, but these studies have not yet adequately addressed the therapeutic needs of neonates. Additionally, extant guidance developed by regulatory agencies worldwide does not fully address the specificities of neonatal drug development, especially among extremely premature newborns who currently survive. Consequently, an international consortium from Canada, Europe, Japan, and the United States was organized by the Critical Path Institute to address the content of guidance...

Not all births are happy occasions. As an obstetrician, I have helped many families as they experienced stillbirths and untimely deliveries over the last thirty years. During the last ten years I have witnessed a disturbing phenomenon: preterm babies dying needlessly because they are being denied life-sustaining interventions. I remember the families who were simply told their 23-week newborns would die because "all of them do". I remember the families who were told "we do not recommend intensive care for babies born at 24 weeks because when they survive their outcomes are bleak"...

The neurodevelopmental impact of fentanyl given to preterm newborns for pain control is still unknown. The aim of this study was to assess the neurodevelopmental impact of 2 regimens of fentanyl administration by a prospective follow-up evaluation. In our previous multicenter, double-blind, randomized controlled trial, 131 mechanically ventilated newborns (gestational age ≤32 weeks) were randomized to fentanyl (continuous infusion of fentanyl + open label boluses of fentanyl) or placebo (continuous infusion of placebo + open label boluses of fentanyl)...
