Signaling via the colony stimulating factor 1 receptor (CSF1R) controls the survival, differentiation and proliferation of macrophages. Mutations in CSF1, or CSF1R in mice and rats have pleiotropic effects on postnatal somatic growth. We tested the possible application of CSF1-Fc as a therapy for low birth weight (LBW) at term, using a model based upon maternal dexamethasone treatment in rats. Neonatal CSF1-Fc treatment did not alter somatic growth, and did not increase the blood monocyte count. Instead, there was a substantial increase in the size of liver in both control and LBW rats, and the treatment greatly exacerbated the lipid droplet accumulation seen in the dexamethasone LBW model...

BACKGROUND: Early bystander cardiopulmonary resuscitation (CPR) for cardiac arrest is crucial in the chain of survival. Cardiac arrest in infants is rare but CPR is also performed in severe bradycardia. The European Resuscitation Council (ERC) and American Heart Association (AHA) guidelines recommend starting CPR and continuing it until the heart muscle is sufficiently oxygenated and regains sufficient contractility and function. Among the techniques of CPR that can be applied in newborns, the most common and therefore recommended by the ERC and AHA are the two-finger technique and two-thumb technique...

Lung immaturity is the major cause of morbidity and mortality in premature infants, especially those born <28 weeks of gestation. These infants are at high risk of developing respiratory distress syndrome (RDS), a lung disease caused by insufficient surfactant production and immaturity of saccular/alveolar type II epithelial cells in the lung. RDS treatment includes oxygen and respiratory support that improve survival but also increase the risk for bronchopulmonary dysplasia (BPD), a chronic lung disease characterized by arrested alveolarization, airway hyperreactivity, and pulmonary hypertension...

BACKGROUND: Intrapartum-related hypoxia accounts for 30% of neonatal deaths in Tanzania. This has led to the introduction and scaling-up of the Helping Babies Breathe (HBB) programme, which is a simulation-based learning programme in newborn resuscitation skills. Studies have documented ineffective ventilation of non-breathing newborns and the inability to follow the HBB algorithm among providers. OBJECTIVE: This study aimed at exploring barriers and facilitators to effective bag mask ventilation, an essential component of the HBB algorithm, during actual newborn resuscitation in rural Tanzania...

Harlequin Ichthyosis is a very rare genetic disorder affecting mainly the skin with severe morbidity and mortality. It affects both sexes with incidence of about 1 in 300,000 live births. Autosomal recessive inheritance has been inferred with mutation in ABCA 12 gene identified. Hence, genetic counseling and mutation screening of this gene should be considered in at-risk patients. Death usually occurred in the first 3 months of life due to sepsis, feeding problems and respiratory distress. With improved neonatal care and early introduction of retinoids, its survival rate has increased...

As perinatal and postnatal care of neonates with impaired kidney function is constantly improving, the number of infants needing renal replacement therapy is increasing. Consequently, the general attitude of clinicians to offer renal replacement therapy (RRT) during the first year of life is changing gradually. The ideal renal replacement modality for children and adolescents is renal transplantation (RTX), as both the short-term and long-term medical complications of hemo- and peritoneal dialysis confer inferior survival rates compared to RTX to this patent group...

Escherichia coli K1 strains are major causative agents of invasive disease of the new born. The age dependency of infection can be reproduced in the neonatal rat. Colonization of the small intestine following oral administration of K1 bacteria leads rapidly to invasion of the blood circulation; bacteria that avoid capture by the mesenteric lymphatic system and evade antibacterial mechanisms in the blood may disseminate to cause organ-specific infections such as meningitis. Some E. coli K1 surface constituents, in particular the polysialic acid capsule, are known to contribute to invasive potential but a comprehensive picture of the factors that determine the fully virulent phenotype has not so far emerged...

BACKGROUND: A community-based intervention comprising both men and women, known as Safe Motherhood Action Groups (SMAGs), was implemented in four of Zambia's poorest and most remote districts to improve coverage of selected maternal and neonatal health interventions. This paper reports on outcomes in the coverage of maternal and neonatal care interventions, including antenatal care (ANC), skilled birth attendance (SBA) and postnatal care (PNC) in the study areas. METHODOLOGY: Three serial cross-sectional surveys were conducted between 2012 and 2015 among 1,652 mothers of children 0-5 months of age using a 'before-and-after' evaluation design with multi-stage sampling, combining probability proportional to size and simple random sampling...

Extracorporeal membrane oxygenation (ECMO), a life-saving therapy for respiratory and cardiac failure, was first used in neonates in the 1970s. The indications and criteria for ECMO have changed over the years, but it continues to be an important option for those who have failed other medical therapies. Since the Extracorporeal Life Support Organization (ELSO) Registry was established in 1989, more than 29,900 neonates have been placed on ECMO for respiratory failure, with 84% surviving their ECMO course, and 73% surviving to discharge or transfer...

Bronchopulmonary dysplasia (BPD) is the most common long-term complication in surviving extremely preterm infants. This may lead to pulmonary hypertension, increase late neonatal mortality, and cause abnormal neural development. There is still controversy over the efficacy, as well as advantages and disadvantages, of drug therapy for BPD in preterm infants. This article reviews the research progress in the drug therapy for BPD.

OBJECTIVE: To evaluate the value of blood lactic acid (BLA) as a predictor for the severity and prognosis of neonatal shock. METHODS: A total of 326 neonates with shock were enrolled and divided into three groups based on the severity, namely mild group (n=147), moderate group (n=105), and severe group (n=74). BLA level was measured during and early after (about 6 hours later) fluid resuscitation, and lactate clearance rate (LCR) was calculated. The receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of BLA in neonatal shock...

ECMO has proven to be a life-saving intervention for a variety of disease entities with a high rate of survival in the neonatal population. However, ECMO requires clinical teams to engage in many ethical considerations. Even with ongoing improvements in technology and expertise, some patients will not survive a course of ECMO. An unsuccessful course of ECMO can be difficult to accept and cause a great deal of angst. These questions can result in real conflict both within the care team, and between the care team and the family...

BACKGROUND: The prevalence of PPHN has been estimated at 1.9 per 1000 live births. After the discovery of iNO's, its efficacy and benefit in PPHN is well established. Even in the best of centers equipped with iNo and ECMO the mortality is around 20%. Also, iNO is expensive and difficult to administer and monitor which makes it difficult choice in our part of the world. Furthermore About 40% of patients do not respond or have rebound pulmonary hypertension after discontinuation. Owing to these reasons, other treatment modalities like phosphodiesterase inhibitors such as Sildenafil need to be evaluated...

Ongoing advancements in neonatal care since the late 1980's have led to increased numbers of premature infants surviving well beyond the neonatal period. As a result of increased survival, many individuals born preterm manifest chronic respiratory symptoms throughout infancy, childhood and adult life. The archetypical respiratory disease of prematurity, bronchopulmonary dysplasia (BPD), is the second most common chronic pediatric respiratory disease after asthma. However, there are several commonly held misconceptions...

BACKGROUND: Islet encapsulation techniques have shown limited success in maintaining islet survival and function because encapsulation decreases oxygen supply. In this study, an oxygen-generating scaffold was fabricated to prevent hypoxic cell damage and improve the viability and insulin secretion of islets. METHODS: We fabricated an oxygen-generating scaffold by mixing calcium peroxide (CaO2 ) with polydimethylsiloxane (PDMS). We evaluated the effects of the oxygen-generating PDMS + CaO2 scaffold on viability, caspase-3 and caspase-7 activity, oxygen consumption rate (OCR), glucose-stimulated insulin secretion (GSIS), hypoxic cell marker expression, and reactive oxygen species (ROS) levels in porcine neonatal pancreatic cell clusters (NPCCs)...
