The environment plays a critical role in shaping development and function of the brain. Stress, especially when experienced early in life, can interfere with these processes. In the context of respiratory control, perinatal stress can therefore alter the ability to achieve the "fine-tuning" necessary for proper detection of chemosensory stimuli and production of an adequate motor (respiratory) command. Depending on the timing, intensity, and duration, the detrimental consequences of perinatal exposure to adverse conditions on the respiratory network become manifest at various life stages and can persist into adulthood...

BACKGROUND: Pierre Robin sequence is characterized by mandibular retrognathia and glossoptosis resulting in airway obstruction and feeding difficulties. When conservative management fails, mandibular distraction osteogenesis or tongue-lip adhesion may be required to avoid tracheostomy. The authors' goal was to prospectively evaluate the airway and feeding outcomes of their comprehensive approach to Pierre Robin sequence, which includes conservative management, mandibular distraction osteogenesis, and tongue-lip adhesion...

Sudden demise of a healthy fetus or a neonate is a very tragic episode in the life of parents. These deaths have been a mystery since ages but still remain unexplained. This review proposes the involvement of trigeminal nerve, neurotransmitter substance P (SP), and its receptor neurokinin 1 (NK-1R) in regulation of cardiorespiratory control in fetuses and newborns. Anomalies and immaturity of neuroregulatory systems such as trigeminal system in medulla oblongata of brainstem may provide a possible mechanism of sudden perinatal deaths...

INTRODUCTION: An apnea episode is defined as the cessation of breathing for ≥15 seconds or as any suspension of breathing accompanied by hypoxia and bradycardia. Obtaining information about the respiratory system in a neonate can be accomplished using electromyography signals from the diaphragm muscle. OBJECTIVE: The purpose of this paper is to illustrate a method by which the respiratory and electrocardiographic signals from neonates can be obtained using diaphragmatic electromyography...

Caffeine is widely used for the treatment of apnea of prematurity (AoP) but whether this effect varies with sex is unknown. To shed some light on this question, we present a summary of data obtained on the effects of caffeine on the respiratory chemoreflexes and apnea frequency in 1- and 12-days old male and female rats. Caffeine was either administered as a single acute injection (10mg/kg, i.p.) or for 10 consecutive days (7.5mg/kg/day between 3 and 12days of life by gavage, simulating its clinical use). Acute caffeine had little effects on breathing in 1-day old male and female rats...

INTRODUCTION: Neonatal respiratory disorders are a leading cause of perinatal mortality due to complications resulting from premature births and prenatal exposure to drugs of abuse, but optimal treatments for these symptoms are still unclear due to a variety of confounds and risk factors. Mouse models present an opportunity to study the underlying mechanisms and efficacy of potential treatments of these conditions with controlled variables. However, measuring respiration in newborn mice is difficult and commercial components are expensive and often require modification, creating a barrier and limiting our understanding of the short and long-term effects of birth complications on respiratory function...

BACKGROUND: Caffeine is widely used to manage apnea of prematurity, and reduces the incidence of bronchopulmonary dysplasia (BPD). Deregulated transforming growth factor (TGF)-β signaling underlies arrested post-natal lung maturation in BPD. It is unclear whether caffeine impacts TGF-β signaling or post-natal lung development in affected lungs. METHODS: The impact of caffeine on TGF-β signaling in primary mouse lung fibroblasts and alveolar epithelial type II cells was assessed in vitro...

BACKGROUND The emergence of infections related to multidrug-resistant Gram-negative bacilli (MDR-GNB) reintroduced the use of colistin, an antibiotic that was previously abandoned due to adverse effects. However, because of its limited use in neonatal intensive care units, there is very little data about the effectiveness and safety of colistin in children and newborns. In this study, which will be the largest case study in the literature, we aimed to evaluate the effectiveness and safety of colistin in full-term and preterm newborns...

BACKGROUND: Micrognathia is a congenital anomaly that may pose breathing and feeding limitations in newborns, sometimes necessitating invasive management. The present study aims to identify the complications associated with receiving mandibular surgery during the birth stay in order to better predict which patients may benefit from early surgical intervention. METHODS: A retrospective cohort study was performed using the 2000 to 2012 kids' inpatient databases. We included all live newborn infants born in the hospital through vaginal delivery or caesarean section...

Congenital hyperinsulinism (CHI) is a rare condition that can cause irreversible brain damage during the neonatal period owing to the associated hypoglycemia. Hypoglycemia in CHI occurs secondary to the dysregulation of insulin secretion. CHI has been established as a genetic disorder of islet-cell hyperplasia, associated with a mutation of the ABCC8 or KCNJ11 genes, which encode the sulfonylurea receptor 1 and the inward rectifying potassium channel (Kir6.2) subunit of the ATP-sensitive potassium channel, respectively...

Mydriatic drops are routinely administered to premature neonates to screen for retinopathy of prematurity. Adverse anticholinergic side effects, particularly convulsions and tachycardia have been reported in the pediatric age group following instillation of mydriatics for diagnostic fundus examination [1, 2]. Caffeine is frequently used for apnea of prematurity. In the neonatal intensive care unit, the combined use of caffeine and mydriatic drops is a common practice. Here we report two cases of atrial arrhythmias after neonatal eye exam that improved with conservative management...

PURPOSE: Newborns are often sedated during MRI but sedation itself creates adverse events and management is more challenging in this environment. Oral glucose/sucrose administration has been studied in newborns during painful procedures; however, its effectiveness in keeping newborns sleepy and motionlessness during painless procedures has not been demonstrated. The objective of this study was to describe effectiveness of oral 30% glucose administration by comparing with intravenous midazolam sedation for newborns during MRI...

A unified approach to contact-less and low-cost video processing for automatic detection of neonatal diseases characterized by specific movement patterns is presented. This disease category includes neonatal clonic seizures and apneas. Both disorders are characterized by the presence or absence, respectively, of periodic movements of parts of the body-e.g., the limbs in case of clonic seizures and the chest/abdomen in case of apneas. Therefore, one can analyze the data obtained from multiple video sensors placed around a patient, extracting relevant motion signals and estimating, using the Maximum Likelihood (ML) criterion, their possible periodicity...

Hyperbilirubinemia (HB) occurs in 90% of preterm newborns. Moderate HB can induce acute neurological disorders while severe HB has been linked to a higher incidence of apneas of prematurity. The present study aimed to test the hypothesis that even moderate HB disrupts cardiorespiratory control in preterm lambs. Two groups of preterm lambs (born 14 days prior to term), namely control (n = 6) and HB (n = 5), were studied. At day 5 of life, moderate HB (150-250 μmol/L) was induced during 17 h in the HB group after which cardiorespiratory control as well as laryngeal and pulmonary chemoreflexes were assessed during baseline recordings and during hypoxia...

The biological functions of the Janus kinase 1 (JAK1) are suggested to be pleiotropic since this signal transducer is ubiquitously expressed and coupled to a variety of cytokine receptors. Consequently, mice that are deficient in this tyrosine kinase were reported to die shortly after birth. To facilitate studies that address the biological and molecular functions of JAK1 during postnatal development, we performed gene targeting in embryonic stem cells and generated a Cre/lox-based conditional knockout mouse model...

UNLABELLED: Neurally adjusted ventilatory assist (NAVA) improves patient-ventilator synchrony during invasive ventilation and leads to lower peak inspiratory pressures (PIP) and oxygen requirements. The aim of this trial was to compare NAVA with current standard ventilation in preterm infants in terms of the duration of invasive ventilation. Sixty infants born between 28 + 0 and 36 + 6 weeks of gestation and requiring invasive ventilation due to neonatal respiratory distress syndrome (RDS) were randomized to conventional ventilation or NAVA...

The carotid body (CB) substantially influences breathing in premature infants by affecting the frequency of apnea and periodic breathing. In adult animals, inflammation alters the structure and chemosensitivity of the CB, yet it is not known if this pertains to neonates. We hypothesized that early postnatal inflammation leads to morphological and functional changes in the developing rat CB, which persists for one week after the initial provoking insult. To test our hypothesis, we exposed rat pups at postnatal day 2 (P2) to lipopolysaccharide (LPS; 100 µg/kg) or saline (SAL) intraperitoneally (IP)...

Objective To determine the frequency of cardiorespiratory events following routine exams for retinopathy of prematurity (ROP). Study Design This is a retrospective review of 79 premature infants in the neonatal intensive care unit at the University of Rochester Medical Center. The baseline for each infant (mean cardiorespiratory events in the 72 hours before the exam) was compared with the number of cardiorespiratory events during the subsequent 24 hours using generalized estimating equation and the Mantel-Haenszel chi-square test to determine if there was an association between cardiorespiratory events and potential risk factors...
