BACKGROUND: While there are good data to describe changing trends in mortality and morbidity rates for preterm populations, there is very little information on the specific causes and pattern of death in terms of age of vulnerability. It is well established that mortality increases with decreasing gestational age but there are limited data on the specific causes that account for this increased mortality. The aim of this study was to establish the common causes of hospital mortality in a regional preterm population admitted to a neonatal intensive care unit (NICU)...

Objective Administered in a timely manner, current evidence-based interventions could reduce neonatal deaths from infections, intrapartum injuries and complications due to prematurity. The three delays model (delay in seeking care, in arriving at a health facility, and in receiving adequate care), which has been applied to understanding maternal deaths, may be useful for understanding neonatal deaths. We assess the main causes of neonatal deaths in Rwanda and their associated delays. Methods Using a cross-sectional study design, we evaluated data from 2012 from 40 facilities in which babies were delivered...

Hypoxic-ischemic encephalopathy (HIE) secondary to perinatal asphyxia is a leading cause of mortality and acquired long-term neurologic co-morbidities in the neonate. The most successful intervention for the treatment of moderate to severe HIE is moderate whole body hypothermia initiated within 6h from birth. The objective and prompt identification of infants who are at risk of developing moderate to severe HIE in the critical first hours still remains a challenge. This work proposes a metabolite score calculated based on the relative intensities of three metabolites (choline, 6,8-dihydroxypurine and hypoxanthine) that showed maximum correlation with hypoxia time in a consolidated piglet model for neonatal hypoxia-ischemia...

In recent decades, we have observed a remarkable increase in the rate of caesarean section (CS) in both developed and developing countries, especially in China. According to the World Health Organization (WHO) systematic review, if the increase in CS rate was between 10% and 15%, the maternal and neonatal mortality was decreased. However, above this level, increasing the rate of CS is no longer associated with reduced mortality. To date, no consensus has been reached on the main factors driving the cesarean epidemic...

Discharge against medical advice (DAMA) conflicts with the purpose of disease treatment in children. Some research has shown that there are high proportions of extremely preterm infants and infants with asphyxia or congenital malformation in neonates with DAMA. This suggests that the sustainable development of neonatology needs cooperation and co-development with obstetrics, neonatal surgery, and radiology to reduce the rate of DAMA. With reference to the current status of research in both China and other countries, this article reviews the causes for DAMA and the strategies for reducing the rate of DAMA, in order to provide a theoretical basis for effectively reducing the rate of DAMA from the neonatal intensive care unit, improving treatment outcomes of the neonates, and increasing hospitals' comprehensive benefits...

Cardiopulmonary resuscitation (CPR) duration until return of spontaneous circulation (ROSC) influences survival and neurologic outcomes after delivery room (DR) CPR. High quality chest compressions (CC) improve cerebral and myocardial perfusion. Improved myocardial perfusion increases the likelihood of a faster ROSC. Thus, optimizing CC quality may improve outcomes both by preserving cerebral blood flow during CPR and by reducing the recovery time. CC quality is determined by rate, CC to ventilation (C:V) ratio, and applied force, which are influenced by the CC provider...

Severe gastrointestinal bleeding in newborn period is a serious but uncommon phenomenon that has a broad differential diagnosis. Primary duodenal ulcers are rare in children but stress induced ulceration in stomach occurs more often in neonatal period due to birth asphyxia, prolonged labour, cesarean deliveries, instrumentations, respiratory distress syndrome and sepsis. These present as acute onset of gastrointestinal bleeding commonly as altered gastric aspirate, hematemesis or malena. We report a case of a neonate with stress induced gastric bleeding following birth asphyxia who presented with massive gastrointestinal bleed manifesting as hematemesis and massive rectal bleeding...

BACKGROUND: Cardiac troponin I (cTnI) is a well-established marker for detecting myocardial ischemic damage in neonates with hypoxic-ischemic encephalopathy. However, the predictive value of cTnI in assessing mortality in neonatal asphyxia remains obscure. This retrospective study aims to analyze the relationship between cTnI levels in blood serum with gestational age, birth weight, gender, delivery type, electrocardiography, echocardiography, Apgar scores, length of hospital stay, and mortality in asphyxiated neonates...

Hypoxic-ischemic encephalopathy remains a common cause of brain damage in neonates. Preterm infants have additional complications, as prematurity by itself increases the risk of encephalopathy. Currently, therapy for this subset of asphyxiated infants is limited to supportive care. There is an urgent need for therapies in preterm infants - and for representative animal models for preclinical drug development. In 1991, a novel rodent model of global asphyxia in the preterm infant was developed in Sweden. This method was based on the induction of asphyxia during the birth processes itself by submerging pups, still in the uterine horns, in a water bath followed by C-section...

BACKGROUND: In neonates requiring chest compression (CC) during resuscitation, neonatal resuscitation program (NRP) recommends against relying on a single feedback device such as end-tidal carbon dioxide (ETCO2) or SpO2 to determine return of spontaneous circulation (ROSC) until more evidence becomes available. METHODS: We evaluated the role of monitoring ETCO2 during resuscitation in a lamb model of cardiac arrest induced by umbilical cord occlusion (n=21). Lambs were resuscitated as per NRP guidelines...

BACKGROUND: Perinatal hypoxic-ischemic brain damage is a major cause of acute mortality and chronic neurological morbidity in infants and children. Oxidative stress due to free radical formation and the initiation of abnormal oxidative reactions appears to play a key role. Docosahexanoic acid (DHA), a main component of brain membrane phospholipids, may act as a neuroprotectant after hypoxia-ischemia by regulating multiple molecular pathways and gene expression. OBJECTIVES: The aims of this study were to test the hypothesis that DHA provides significant protection against lipoperoxidation damage in the cerebral cortex and hippocampus in a neonatal piglet model of severe hypoxia-reoxygenation...

Encephalopathy due to perinatal asphyxia (PA) is a major cause of neonatal morbidity and mortality in the period around birth. Preterm infants are especially at risk for cognitive, attention and motor impairments. Therapy for this subgroup is limited to supportive care, and new targets are thus urgently needed. Post-asphyxic excitotoxicity is partially mediated by excessive nitric oxide (NO) release. The aims of this study were to determine the timing and distribution of nitric oxide (NO) production after global PA in brain areas involved in motor regulation and coordination...

Neonatal acute kidney injury is common, in part due to incomplete renal maturation and also due to frequent exposure to risk factors for acute kidney injury such as perinatal asphyxia, extracorporeal-membrane-oxygenation, cardiac surgery, sepsis, prematurity and nephrotoxicity. However the current method by which acute kidney injury is diagnosed is sub-optimal and not universally accepted which impairs the accurate estimation of the true incidence of neonatal acute kidney injury. Serum Cystatin-C, urinary NGAL, KIM-1 and IL-18 are promising neonatal acute kidney injury biomarkers however the diagnosis of acute kidney injury remains serum creatinine/urine output-based in many studies...
