BACKGROUND: During synchronised mechanical ventilation, positive airway pressure and spontaneous inspiration coincide. If synchronous ventilation is provoked, adequate gas exchange should be achieved at lower peak airway pressures, potentially reducing baro/volutrauma, air leak and bronchopulmonary dysplasia. Synchronous ventilation can potentially be achieved by manipulation of rate and inspiratory time during conventional ventilation and employment of patient-triggered ventilation. OBJECTIVES: To compare the efficacy of:(i) synchronised mechanical ventilation, delivered as high-frequency positive pressure ventilation (HFPPV) or patient-triggered ventilation (assist control ventilation (ACV) and synchronous intermittent mandatory ventilation (SIMV)), with conventional ventilation or high-frequency oscillation (HFO);(ii) different types of triggered ventilation (ACV, SIMV, pressure-regulated volume control ventilation (PRVCV), SIMV with pressure support (PS) and pressure support ventilation (PSV))...

OBJECTIVE: Accurate and validated predictors of outcome for infants with congenital diaphragmatic hernia are needed. Score for Neonatal Acute Physiology-II has been validated to predict mortality in newborns. We investigated whether Score for Neonatal Acute Physiology-II scores in congenital diaphragmatic hernia could predict mortality, need for extracorporeal membrane oxygenation (in patients born in a center with extracorporeal membrane oxygenation availability), and development of bronchopulmonary dysplasia (oxygen dependency beyond 28 d after birth) in survivors...

UNLABELLED: The predicitive values of fetal ultrasonography and magnetic resonance imaging are well established as antenatal outcome predictors in neonates with congenital diaphragmatic hernia (CHD). Postnatal outcome predictors remain elusive. THE AIM: To evaluate the value of the oxygenation index (OI) as a predictor of postnatal survival. MATERIAL AND METHODS: 58 newborns with congenital diaphragmatic hernia, treated in the same centre (a university hospital) between February 2006 and March 2014 were involved in the retrospective study...

BACKGROUND: Internationally the need for neonatal ECMO is decreasing and the Extracorporeal Life Support Organization (ELSO) recommends that centres providing neonatal ECMO should treat at least 6 children per year. METHOD: After a one-year training programme and preparation of the clinical application, neonatal ECMO was established and subsequently 41 infants [median age 1 day (1-172 days), median weight 3.25 kg (1.27-5.79 kg)] with severe respiratory failure have been treated within a 6-year period (fall 2008-fall 2014)...

BACKGROUND: Children who require mechanical ventilation represent a high-risk population with significant morbidity and mortality. Experienced handling of conventional therapies including high frequency oscillation ventilation and initiation of newer treatment options such as surfactant or nitric oxide has led to some improvements. Nevertheless, extracorporeal membrane oxygenation (ECMO) is a life-saving technology in patients with respiratory failure refractory to maximal medical therapy...

REVIEW

BACKGROUND: Respiratory failure due to lung immaturity is a major cause of mortality in preterm infants. Although the use of intermittent positive pressure ventilation (IPPV) in neonates with respiratory failure saves lives, its use is associated with lung injury and chronic lung disease. A newer form of ventilation called high frequency oscillatory ventilation has been shown in experimental studies to result in less lung injury. OBJECTIVES: The objective of this review was to determine the effect of the elective use of high frequency oscillatory ventilation (HFOV) as compared to conventional ventilation (CV) on the incidence of chronic lung disease (CLD), mortality and other complications associated with prematurity and assisted ventilation in preterm infants who were mechanically ventilated for respiratory distress syndrome (RDS)...

In the present study, we investigated the effects of infra-red laser irradiation on sarcomere dynamics in living neonatal cardiomyocytes of the rat. A rapid increase in temperature to >~38 °C induced [Ca(2+)]i-independent high-frequency (~5-10 Hz) sarcomeric auto-oscillations (Hyperthermal Sarcomeric Oscillations; HSOs). In myocytes with the intact sarcoplasmic reticular functions, HSOs coexisted with [Ca(2+)]i-dependent spontaneous beating in the same sarcomeres, with markedly varying frequencies (~10 and ~1 Hz for the former and latter, respectively)...

BACKGROUND: Volvulus without malrotation in preterm infants is a rare but potentially life-threatening event of unknown aetiology. Confusion with necrotising enterocolitis may delay surgical intervention thereby aggravating morbidity and mortality. We aimed at elucidating potential risk factors for, and characteristic clinical signs of, volvulus without malrotation in preterm infants. METHODS: Retrospective, single-centre case-control study (2007-2011). For every index patient, five infants of similar gestational age, birth weight and birth year were evaluated...

PURPOSE: We investigated whether oscillating gradient diffusion MRI (dMRI) can provide information on brain microstructural changes after formaldehyde fixation and after hypoxic-ischemic (HI) injury beyond that provided by conventional dMRI. METHODS: Pulsed gradient spin echo (PGSE) and oscillating gradient spin echo (OGSE) dMRI of the adult mouse brain was performed in vivo (50-200 Hz, b = 600 mm(2)/s), and a similar protocol was applied to neonatal mouse brains at 24 h after unilateral hypoxia-ischemia...

BACKGROUND: Lung function data in healthy newborn infants are scarce largely due to lack of suitable techniques, although data for developmental and prenatal exposure studies are much needed. We have modified the forced oscillation technique (FOT) for the measurement of respiratory mechanical impedance (Zrs) in unsedated sleeping infants in the first 3 days of life. METHODS: Zrs was measured during 30-s epochs of quiet sleep in term neonates born via spontaneous vaginal delivery with a non-invasive FOT between 8 and 48 Hz...

Flexible communication within the brain, which relies on oscillatory activity, is not confined to adult neuronal networks. Experimental evidence has documented the presence of discontinuous patterns of oscillatory activity already during early development. Their highly variable spatial and time-frequency organization has been related to region specificity. However, it might be equally due to the absence of unitary criteria for classifying the early activity patterns, since they have been mainly characterized by visual inspection...

BACKGROUND: Electrical cardiometry (EC) is a continuous noninvasive method for measuring cardiac output (CO), but there are limited data on premature infants. We evaluated the utility of EC monitoring by comparing the results obtained using EC to measurements of CO and systemic blood flow using echocardiography (ECHO). METHODS: In this prospective observational study, 40 preterm neonates underwent 108-paired EC and ECHO measurements. RESULTS: There were correlations between EC-CO and left ventricular output (LVO, p < 0...

Fast-spiking, parvalbumin-expressing GABAergic interneurons, a large proportion of which are basket cells (BCs), have a key role in feedforward and feedback inhibition, gamma oscillations and complex information processing. For these functions, fast propagation of action potentials (APs) from the soma to the presynaptic terminals is important. However, the functional properties of interneuron axons remain elusive. We examined interneuron axons by confocally targeted subcellular patch-clamp recording in rat hippocampal slices...

BACKGROUND: Results from an observational study involving neonates suggested that high-frequency oscillatory ventilation (HFOV), as compared with conventional ventilation, was associated with superior small-airway function at follow-up. Data from randomized trials are needed to confirm this finding. METHODS: We studied 319 adolescents who had been born before 29 weeks of gestation and had been enrolled in a multicenter, randomized trial that compared HFOV with conventional ventilation immediately after birth...

UNLABELLED: Although it is well known that 3,4-methylenedioxymethamphetamine (MDMA) can cause various cardiovascular abnormalities and even sudden death from cardiac arrhythmia, whether it has any effect on myocardial gap junctions, which might be one of the targets mediating MDMA-induced cardiotoxicity, remains unclear. OBJECTIVE: To test the hypothesis that MDMA may affect the myocardial gap junction protein connexin43 (Cx43) and induce cardiac dysrhythmia. METHOD: (1) In vivo study: adult rats were treated with a single dose MDMA administration (20mg/kg, i...
