OBJECTIVE: To study the impact of implementing a protocol to standardize the duration of observation in preterm infants with apnea/bradycardia/desaturation spells before hospital discharge on length of stay (LOS) and readmission rates. STUDY DESIGN: A protocol to standardize the duration of in-hospital observation for preterm infants with apnea, bradycardia and desaturation spells who were otherwise ready for discharge was implemented in December 2013. We evaluated the impact of this protocol on the LOS and readmission rates of very low birth weight infants (VLBW)...

BACKGROUND: There are limited data on the effect of bronchopulmonary dysplasia (BPD) on sleep disordered breathing (SDB). We hypothesized that both the severity of prematurity and BPD would increase the likelihood of SDB in early childhood. Our secondary aim was to evaluate the association of demographic factors on the development of SDB. METHODS: This is a retrospective study of patient factors and overnight polysomnogram (PSG) data of children enrolled in our BPD registry between 2008 and 2015...

Apnea in the paediatric population is associated with increased morbidity and mortality in a large number of developed as well as developing countries. It is even more prominent in preterm newborn infants and is commonly referred to as apnea of prematurity. Its current diagnosis and therapy involve the use of traditional technologies which often result in discomfort to the infants due to the use of invasive devices attached to their sensitive skin, especially in overnight clinical sleep analysis (for over 12- or 24-hour period)...

BACKGROUND: Premature and other at-risk infants can experience cardiorespiratory problems when positioned in their car seats. The American Academy of Pediatrics recommends that all premature and at-risk infants undergo a period of observation in their car seat to monitor for apnea, bradycardia, and oxygen desaturation before hospital discharge. This Infant Car Seat Challenge (ICSC) is used to determine readiness for infant travel in a car seat. Infants failing the ICSC are discharged home in car beds and referred for a follow-up screen in the outpatient clinic...

Certain common medical conditions are associated with a higher risk of pediatric obstructive sleep apnea (OSA). A lower threshold for screening is therefore indicated for such patient cohorts. In this article, we briefly discuss the high prevalence of OSA in children born prematurely, and in those with Down syndrome, craniofacial disorders, and neuromuscular disorders. Primary care providers should have an increased index of suspicion for OSA in these children, considering the neurocognitive disability that occurs in these high-risk groups when OSA is left untreated...

Background: Apnea of prematurity often occurs during and following caffeine therapy. We hypothesized that number of apnea events would be impacted by adjustments in caffeine therapy. Materials and Methods: An automated algorithm was used in all infants ≤32 weeks gestation admitted to a level IV Neonatal Intensive Care Unit from 2009 to 2014 to analyze chest impedance, electrocardiogram, and oxygen saturation data around the time of serum caffeine levels, caffeine boluses while on maintenance therapy, and caffeine discontinuation...

RATIONALE: Caffeine in the newborn period shortens the duration of assisted ventilation and reduces the incidence of bronchopulmonary dysplasia, but its effects on respiratory function in later childhood are unknown. OBJECTIVES: To determine if children born <1251 g birthweight who were treated with neonatal caffeine had improved respiratory function at 11 years of age compared with children treated with placebo. METHODS: Children enrolled in the Caffeine for Apnea of Prematurity randomized controlled trial and assessed at the Royal Women's Hospital in Melbourne at 11 years of age had expiratory flow rates measured according to the standards of the American Thoracic Society...

Snoring, chronic rhinitis and fragmentation of sleep are common symptoms in pregnancy, especially in the third trimester. The prevalence of obstructive sleep apnea is also increased in pregnant women and can be associated with pregnancy induced hypertension, preeclampsia and diabetes mellitus. The fetus is as well exposed to a higher risk of prematurity and intra-uterine growth restriction. Given the lack of adequate screening tool, the diagnosis of obstructive sleep apnea is a challenge for the physician and a high degree of clinical suspicion is necessary in order to identify the patients at risk and propose an appropriate management...

Apnea of prematurity (AOP) can affect even 85-100% of premature newborns and is related to lack of full maturity of organs. AOP is manifesting by 15-20 seconds cessations of breathing accompanied by bradycardia and oxygen desaturation, what can lead to hypoxia or death. Therefore it is very important to implement the effective and safe treatment immediately after birth. Widely used caffeine citrate, which stimulates the respiratory system, improving the working of the respiratory muscles. However the metabolism of caffeine citrate is difficult in preterm infants due to the immaturity of the hepatic enzyme system, what can lead to the occurrence of side effects and toxicity...

BACKGROUND: Polymorphic premature ventricular complexes (PVCs) are very common, appearing most frequently in patients with hypertension, obesity, sleep apnea, and structural heart disease. Sympathetic hyperactivity plays a critical role in the development, maintenance, and aggravation of ventricular arrhythmias. Endurance exercise training clearly lowers sympathetic activity in sympatho-excitatory disease states and may be tolerated by patients with chronic kidney disease (CKD). METHODS: We assessed 40 CKD patients with hypertension with polymorphic PVCs...

KEY POINTS: The ventilatory response to reduced oxygen (hypoxia) is biphasic, comprising an initial increase in ventilation followed by a secondary depression. Our findings indicate that, during hypoxia, astrocytes in the pre-Bötzinger complex (preBötC), a critical site of inspiratory rhythm generation, release a gliotransmitter that acts via P2Y1 receptors to stimulate ventilation and reduce the secondary depression. In vitro analyses reveal that ATP excitation of the preBötC involves P2Y1 receptor-mediated release of Ca(2+) from intracellular stores...

BACKGROUND: Prader-Willi syndrome (PWS) is a rare congenital disease that affects growth, sexual development, cognitive function and behavior. Individuals exhibit food preoccupation and hyperphagia, which may lead to obesity with premature morbidity and mortality. The aim of this work was to evaluate the risk of venous thromboembolisms (VTEs), myocardial infarction, pulmonary hypertension, sleep apnea, depression, anxiety and all-cause mortality among persons with PWS as compared with an age- and sex-matched general-population cohort...

PURPOSE: We exposed premature infants to womb-like sounds to evaluate such exposure on breathing and cardiovascular patterns. We hypothesized that these sounds would reduce apnea and intermittent hypoxemia, enhance parasympathetic outflow, and improve cardiovascular patterns. METHODS: A total of 20 cases and 5 control infants at ≤32-36 weeks corrected gestational age participated in a prospective observational cohort study. Twenty-four hours of continuous ECG, respiratory and oxygen saturation data were collected in all infants...

BACKGROUND: Autonomic dysfunction contributes to atrial fibrillation (AF). OBJECTIVE: We hypothesized that polysomnogram (PSG)-based heart rate variability (HRV) autonomic function biomarkers are associated with incident AF and these associations are modified by measures of sleep disordered breathing (SDB). METHODS: 2350 participants of a multi-center prospective study (Outcomes of Sleep Disorders in Older Men Study) without baseline AF underwent sleep studies with incident adjudicated AF follow up (8...

Caffeine citrate is one of the most prescribed drug in the present day NICU for apnea. Its efficacy, tolerability, wide therapeutic index and safety margin has made it the drug of choice among the methylxanthines. Its therapeutic uses in apnea of prematurity, mechanical ventilation, bronchopulmonary dysplasia has made it a "silver bullet" in neonatology. However, there are still controversies surrounding this drug. This review is aimed to update the reader about the basic pharmacology, current therapeutic uses, adverse effects, controversies as well as present and future research of caffeine...
