Abstract BACKGROUND Lung recruitment at birth has been advocated as an effective method of improving the respiratory transition at birth. Sustained inflations (SI) and dynamic positive end-expiratory pressure (PEEP) were assessed in clinical and animal studies to define the optimal level. Our working hypothesis was that very low gestational age infants (VLGAI) < 32 weeks’ gestation require an individualized lung recruitment based on combining both manoeuvers. METHODS Between 2014 and 2016, 100 and 102 inborn VLGAI were enrolled before and after introducing these manoeuvers based on progressive increase in SI up to 15 seconds, with simultaneous gradual increase in PEEP up to 15 cmH2O, according to the cardiorespiratory response. Retrospective comparisons of the rate of mechanical ventilation (MV) < 72h of life, short- and mid-term morbidity were then performed. RESULTS Among extremely low gestational age infants (ELGAI) < 29 weeks’ gestation, MV and its mean duration < 72h of life, consumption of a 2 nd dose of surfactant, and postnatal corticosteroids decreased significantly from 92 to 71%, 42 to 12h, 35 to 12%, and 49 to 24%, respectively. Among VLGAI, most of these results, and the rate of bronchopulmonary dysplasia (decreasing from 14 to 6%), were significant after a multivariate analysis. Neonatal mortality and morbidity were not different. CONCLUSIONS In our setting, combining two individualized lung recruitment maneuvers at birth was feasible and may be beneficial on short- and mid-term pulmonary outcomes, especially in ELGAI < 29 weeks’ gestation. A randomized controlled trial is needed to confirm these results.

Abstract BACKGROUND Lung recruitment at birth has been advocated as an effective method of improving the respiratory transition at birth. Sustained inflations (SI) and dynamic positive end-expiratory pressure (PEEP) were assessed in clinical and animal studies to define the optimal level. Our working hypothesis was that very low gestational age infants (VLGAI) < 32 weeks’ gestation require an individualized lung recruitment based on combining both manoeuvers. METHODS Between 2014 and 2016, 91 and 72 inborn VLGAI, requiring a respiratory support beyond a continuous positive airway pressure (CPAP) = 5 cmH2O, were enrolled before and after introducing these manoeuvers based on progressive increase in SI up to 15 seconds, with simultaneous gradual increase in PEEP up to 15 cmH2O, according to the cardiorespiratory response. Retrospective comparisons of the incidence of mechanical ventilation (MV) < 72h of life, short-term and before discharge morbidity were then performed. RESULTS Among extremely low gestational age infants (ELGAI) < 29 weeks’ gestation, the following outcomes decreased significantly: intubation (90% to 55%) and surfactant administration (54% to 12%) in the delivery room, MV (92% to 71%) and its mean duration < 72h of life (45h to 13h), administration of a 2nd dose of surfactant (35% to 12%) and postnatal corticosteroids (52% to 19%), and the rate of bronchopulmonary dysplasia (23 to 5%). Among VLGAI, all of these results were also significant. Neonatal mortality and morbidity were not different. CONCLUSIONS In our setting, combining two individualized lung recruitment maneuvers at birth was feasible and may be beneficial on short-term and before discharge pulmonary outcomes. A randomized controlled trial is needed to confirm these results.

Objective The aim of the study is to describe the rates of neonatal death and severe neonatal morbidity in a contemporary cohort, as well as to evaluate the predictive value of birth gestational age (GA) and birth weight, independently and combined, for neonatal mortality and morbidity in the same contemporary cohort. Study Design We performed a secondary analysis of an international, multicenter randomized controlled trial of delayed umbilical cord clamping versus umbilical cord milking in preterm infants born at 23 0/7 to 31 6/7 weeks of gestation. The current analysis was restricted to infants delivered <28 weeks. The primary outcomes of this analysis were neonatal death and a composite of severe neonatal morbidity. Incidence of outcomes was compared by weeks of GA, with planned subanalysis comparing small for gestational age (SGA) versus non-SGA neonates. Multivariable logistic regression was then used to model these outcomes based on birth GA, birth weight, or a combination of both as primary independent predictors to determine which had superior ability to predict outcomes. Results Of 474 neonates in the original trial, 180 (38%) were included in this analysis. Overall, death occurred in 27 (15%) and severe morbidity in 139 (77%) neonates. Rates of mortality and morbidity declined with increasing GA (mortality 54% at 23 vs. 9% at 27 weeks). SGA infants (n = 25) had significantly higher mortality compared with non-SGA infants across all GAs (p < 0.01). There was no difference in the predictive value for neonatal death or severe morbidity between the three prediction options (GA, birth weight, or GA and birth weight). Conclusion Death and severe neonatal morbidity declined with advancing GA, with higher rates of death in SGA infants. Birth GA and birth weight were both good predictors of outcomes; however, combining the two was not more predictive, even in SGA infants. Key Points

Reduced Water

Natural reduced water is natural water that contains active hydrogen and reduces oxidation. It is rare in the world, and in Japan, it is produced in the Hita area of Oita Prefecture (Hita Tenryosui water). Previous studies in humans have examined the effects of natural reduced water on diabetes, which is one of the known risks for dementia. Animal studies of natural reduced water have revealed anti-obesity and anti-anxiety effects. However, the effects of natural reduced water on cognitive function, body composition, and psychological function in humans are unknown. Therefore, we investigated the relationship between these items in elderly people who continuously consume natural reduced water. In this study, we recruited participants aged between 65 and 74 years. The participants were randomly and blindly assigned to a natural reduced water (Hita Tenryosui water) group or a control (tap water) group and drank 1 L of water daily for 6 months. Cognitive function, body composition, and psychological function were measured before and after the 6-month intervention period.

AbstractBackgroundTherapeutic management of pain in patients with complex regional pain syndrome (CRPS) is challenging. Repetitive transcranial magnetic stimulation (rTMS) has analgesic effects on several types of pain. However, its effect on CRPS has not been elucidated clearly. Therefore, we conducted a meta-analysis of the available clinical studies on rTMS treatment in patients with CRPS.Materials and methodsA comprehensive literature search was conducted using the PubMed, EMBASE, Cochrane Library, and SCOPUS databases. We included studies published up to February 09, 2020, that fulfilled our inclusion and exclusion criteria. Data regarding measurement of pain using the visual analog scale before and after rTMS treatment were collected to perform the meta-analysis. The meta-analysis was performed using Comprehensive Meta-analysis Version 2.ResultsA total of three studies (one randomized controlled trial and two prospective observational studies) involving 41 patients were included in this meta-analysis. No significant reduction in pain was observed immediately after one rTMS treatment session or immediately after the entire schedule of rTMS treatment sessions (5 or 10 sessions; P > 0.05). However, pain significantly reduced 1 week after the entire schedule of rTMS sessions (P < 0.001).ConclusionrTMS appears to have a functional analgesic effect in patients with CRPS.

Inflammatory Effect

<b>Introduction:</b> Macrolides have anti-inflammatory and immunomodulatory properties that give this class of antibiotics a role that differs from its classical use as an antibiotic, which opens new therapeutic possibilities. <b>Objective:</b> The aim of this study was to evaluate the anti-inflammatory effect of azithromycin in preventing mechanical ventilation (MV)-induced lung injury in very-low-birth-weight preterm neonates. <b>Methods:</b> This is a randomized, double-blind, placebo-controlled trial of preterm neonates who received invasive MV within 72 h of birth. Patients were randomized to receive intravenous azithromycin (at a dose of 10/mg/kg/day for 5 days) or placebo (0.9% saline) within 12 h of the start of MV. Two blood samples were collected (before and after intervention) for measurement of interleukins (ILs) and PCR for <i>Ureaplasma</i>. Patients were followed up throughout the hospital stay for the outcomes of death and bronchopulmonary dysplasia defined as need for oxygen for a period of ≥28 days of life (registered at ClinicalTrials.gov, No. NCT03485703). <b>Results:</b> Forty patients were analyzed in the azithromycin group and 40 in the placebo group. Five days after the last dose, serum IL-2 and IL-8 levels dropped significantly in the azithromycin group. There was a significant reduction in the incidence of death and O<sub>2</sub> dependency at 28 days/death in azithromycin-treated patients regardless of the detection of <i>Ureaplasma</i> in blood. <b>Conclusions:</b> Azithromycin has anti-inflammatory effects, with a decrease in cytokines after 5 days of use and a reduction in death and O<sub>2</sub> dependency at 28 days/death in mechanically ventilated preterm neonates.

Incidence Risk

Preterm birth (PTB) and early term birth (ETB) are associated with high risks of perinatal mortality and morbidity. While extreme to very PTBs have been extensively studied, studies on infants born at later stages of pregnancy, particularly late PTBs and ETBs, are lacking. In this study, we aimed to assess the incidence, risk factors, and feto-maternal outcomes of PTB and ETB births in Qatar. We examined 15,865 singleton live births using 12-month retrospective registry data from the PEARL-Peristat Study. PTB and ETB incidence rates were 8.8% and 33.7%, respectively. PTB and ETB in-hospital mortality rates were 16.9% and 0.2%, respectively. Advanced maternal age, pre-gestational diabetes mellitus (PGDM), assisted pregnancies, and preterm history independently predicted both PTB and ETB, whereas chromosomal and congenital abnormalities were found to be independent predictors of PTB but not ETB. All groups of PTB and ETB were significantly associated with low birth weight (LBW), large for gestational age (LGA) births, caesarean delivery, and neonatal intensive care unit (NICU)/or death of neonate in labor room (LR)/operation theatre (OT). On the other hand, all or some groups of PTB were significantly associated with small for gestational age (SGA) births, Apgar <7 at 1 and 5 minutes and in-hospital mortality. The findings of this study may serve as a basis for taking better clinical decisions with accurate assessment of risk factors, complications, and predictions of PTB and ETB.
