TL;DR: The following guidelines are a summary of the evidence presented in the 2015 International Consensus on Cardiopulmo nary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR).
Abstract: The following guidelines are a summary of the evidence presented in the 2015 International Consensus on Cardiopulmo nary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR).1,2 Throughout the online version of this publication, live links are provided so the reader can connect directly to systematic reviews on the International Liaison Committee on Resuscitation (ILCOR) Scientific Evidence Evaluation and Review System (SEERS) website. These links are indicated by a combination of letters and numbers (eg, NRP 787). We encourage readers to use the links and review the evidence and appendices. These guidelines apply primarily to newly born infants transitioning from intrauterine to extrauterine life. The recommendations are also applicable to neonates who have completed newborn transition and require resuscitation during the first weeks after birth.3 Practitioners who resuscitate infants at birth or at any time during the initial hospitalization should consider following these guidelines. For purposes of these guidelines, the terms newborn and neonate apply to any infant during the initial hospitalization. The term newly born applies specifically to an infant at the time of birth.3 Immediately after birth, infants who are breathing and crying may undergo delayed cord clamping (see Umbilical Cord Management section). However, until more evidence is available, infants who are not breathing or crying should have the cord clamped (unless part of a delayed cord clamping research protocol), so that resuscitation measures can commence promptly. Approximately 10% of newborns require some assistance to begin breathing at birth. Less than 1% require extensive resuscitation measures,4 such as cardiac compressions and medications. Although most newly born infants successfully transition from intrauterine to extrauterine life without special help, because of the large total number of births, a significant number will require some degree of resuscitation.3 Newly born infants who do not …

TL;DR: The next generation of wearable nanofiltration devices will be able to detect the presence of “silentghosts”, a type of ghostly “ghostly substance” found in the fluid mechanics of the immune system, according to the authors.
Abstract: 1. Newborn resuscitation requires anticipation and preparation by providers who train individually and as teams. 2. Most newly born infants do not require immediate cord clamping or resuscitation and can be evaluated and monitored during skin-to-skin contact with their mothers after birth. 3. Inflation and ventilation of the lungs are the priority in newly born infants who need support after birth. 4. A rise in heart rate is the most important indicator of effective ventilation and response to resuscitative interventions. 5. Pulse oximetry is used to guide oxygen therapy and meet oxygen saturation goals. 6. Chest compressions are provided if there is a poor heart rate response to ventilation after appropriate ventilation corrective steps, which preferably include endotracheal intubation. 7. The heart rate response to chest compressions and medications should be monitored electrocardiographically. 8. If the response to chest compressions is poor, it may be reasonable to provide epinephrine, preferably via the intravenous route. 9. Failure to respond to epinephrine in a newborn with history or examination consistent with blood loss may require volume expansion. 10. If all these steps of resuscitation are effectively completed and there is no heart rate response by 20 minutes, redirection of care should be discussed with the team and family. It is estimated that approximately 10% of newly born infants need help to begin breathing at birth,1–3 and approximately 1% need intensive resuscitative measures to restore cardiorespiratory function.4,5 The neonatal mortality rate in the United States and Canada has fallen from almost 20 per 1000 live births6,7 in the 1960s to the current rate of approximately 4 per 1000 live births. The inability of newly born infants to establish and sustain adequate or spontaneous respiration contributes significantly to these early deaths and to the burden of adverse neurodevelopmental outcome among survivors. Effective and timely resuscitation …

TL;DR: LO is feasible and results in less oxygen exposure, lower oxidative stress, and decreased respiratory morbidities and thus is a reasonable alternative for resuscitation of preterm neonates in the delivery room.
Abstract: OBJECTIVE: To determine whether a limited oxygen strategy (LOX) versus a high oxygen strategy (HOX) during delivery room resuscitation decreases oxidative stress in preterm neonates. METHODS: A randomized trial of neonates of 24 to 34 weeks’ gestational age (GA) who received resuscitation was performed. LOX neonates received room air as the initial resuscitation gas, and fraction of inspired oxygen (Fio 2 ) was adjusted by 10% every 30 seconds to achieve target preductal oxygen saturations (Spo 2 ) as described by the 2010 Neonatal Resuscitation Program guidelines. HOX neonates received 100% O 2 as initial resuscitation gas, and Fio 2 was adjusted by 10% to keep preductal Spo 2 at 85% to 94%. Total hydroperoxide (TH), biological antioxidant potential (BAP), and the oxidative balance ratio (BAP/TH) were analyzed in cord blood and the first hour of life. Secondary outcomes included delivery room interventions, respiratory support on NICU admission, and short-term morbidities. RESULTS: Forty-four LOX (GA: 30 ± 3 weeks; birth weight: 1678 ± 634 g) and 44 HOX (GA: 30 ± 3 weeks; birth weight: 1463 ± 606 g) neonates were included. LOX decreased integrated excess oxygen (∑Fio 2 × time [min]) in the delivery room compared with HOX (401 ± 151 vs 662 ± 249; P P P P CONCLUSIONS: LOX is feasible and results in less oxygen exposure, lower oxidative stress, and decreased respiratory morbidities and thus is a reasonable alternative for resuscitation of preterm neonates in the delivery room.

TL;DR: It is concluded that early activation of the NLRP3 inflammasome is a key mechanism in the development of BPD, and represents a novel therapeutic target for BPD.
Abstract: The pathogenesis of bronchopulmonary dysplasia (BPD), a devastating lung disease in preterm infants, includes inflammation, the mechanisms of which are not fully characterized. Here we report that the activation of the NLRP3 inflammasome is associated with the development of BPD. Hyperoxia-exposed neonatal mice have increased caspase-1 activation, IL1β and inflammation, and decreased alveolarization. Nlrp3(-/-) mice have no caspase-1 activity, no IL1β, no inflammatory response and undergo normal alveolarization. Treatment of hyperoxia-exposed mice with either IL1 receptor antagonist to block IL1β or glyburide to block the Nlrp3 inflammasome results in decreased inflammation and increased alveolarization. Ventilated preterm baboons show activation of the NLRP3 inflammasome with increased IL1β:IL1ra ratio. The IL1β:IL1ra ratio in tracheal aspirates from preterm infants with respiratory failure is predictive of the development of BPD. We conclude that early activation of the NLRP3 inflammasome is a key mechanism in the development of BPD, and represents a novel therapeutic target for BPD.

TL;DR: Recent advances in the understanding of NLRP3 activation and regulation are reviewed, the evolving landscape ofNLRP3 modulators are highlighted and opportunities for pharmacologically targeting NL RP3 with novel small molecules are discussed.
Abstract: Danger signals are a hallmark of many common inflammatory diseases, and these stimuli can function to activate the cytosolic innate immune signalling receptor NLRP3 (NOD-, LRR- and pyrin domain-containing 3). Once activated, NLRP3 nucleates the assembly of an inflammasome, leading to caspase 1-mediated proteolytic activation of the interleukin-1β (IL-1β) family of cytokines, and induces an inflammatory, pyroptotic cell death. Pharmacological inhibition of NLRP3 activation results in potent therapeutic effects in a wide variety of rodent models of inflammatory diseases, effects that are mirrored by genetic ablation of NLRP3. Although these findings highlight the potential of NLRP3 as a drug target, an understanding of NLRP3 structure and activation mechanisms is incomplete, which has hampered the discovery and development of novel therapeutics against this target. Here, we review recent advances in our understanding of NLRP3 activation and regulation, highlight the evolving landscape of NLRP3 modulators and discuss opportunities for pharmacologically targeting NLRP3 with novel small molecules.

TL;DR: The fourth update of “European Guidelines for the Management of RDS” by a European panel of experienced neonatologists and an expert perinatal obstetrician based on available literature up to the end of 2018 is reported.
Abstract: As management of respiratory distress syndrome (RDS) advances, clinicians must continually revise their current practice. We report the fourth update of “European Guidelines for the Management of RDS” by a European panel of experienced neonatologists and an expert perinatal obstetrician based on available literature up to the end of 2018. Optimising outcome for babies with RDS includes prediction of risk of preterm delivery, need for appropriate maternal transfer to a perinatal centre and timely use of antenatal steroids. Delivery room management has become more evidence-based, and protocols for lung protection including initiation of CPAP and titration of oxygen should be implemented immediately after birth. Surfactant replacement therapy is a crucial part of management of RDS, and newer protocols for its use recommend early administration and avoidance of mechanical ventilation. Methods of maintaining babies on non-invasive respiratory support have been further developed and may cause less distress and reduce chronic lung disease. As technology for delivering mechanical ventilation improves, the risk of causing lung injury should decrease, although minimising time spent on mechanical ventilation using caffeine and, if necessary, postnatal steroids are also important considerations. Protocols for optimising general care of infants with RDS are also essential with good temperature control, careful fluid and nutritional management, maintenance of perfusion and judicious use of antibiotics all being important determinants of best outcome.
