Weaning of Moderately Preterm Infants from the Incubator to the Crib: A Randomized Clinical Trial

OBJECTIVE: To assess whether length of hospital stay is decreased among moderately preterm infants weaned from incubator to crib at a lower vs higher weight. STUDY DESIGN: This trial was conducted in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Infants with gestational ages 29-33 weeks, birthweight <1600 g, and in an incubator were randomly assigned to a weaning weight of 1600 or 1800 g. Within 60 to 100 g of weaning weight, the incubator temperature was decreased by 1.0°C to 1.5°C every 24 hours until 28.0°C. The infants were weaned to the crib following stable temperature at 36.5°C to 37.4°C for 8 to 12 hours. Clothing and bedcoverings were standardized. The primary outcome was length of hospital stay from birth to discharge; secondary outcomes included length of stay and growth velocity from weaning to discharge. Adverse events were monitored. RESULTS: Of 1565 infants screened, 885 were eligible, and 366 enrolled-187 to the 1600-g and 179 to the 1800-g group. Maternal and neonatal characteristics did not differ among weight groups. Length of hospital stay was a median of 43 days in the lower and 41 days in the higher weight group (P = .12). Growth velocity from completion of weaning to discharge was higher in the lower weight group, 13.7 g/kg/day vs 12.8 g/kg/day (P = .005). Groups did not differ in adverse events. CONCLUSIONS: Among moderately preterm neonates, weaning from incubator to crib at a lower weight did not decrease length of stay, but was safe and was accompanied by higher weight gain after weaning

L'ombra delle 'colonne infami'. La letteratura e l'ingiustizia del capro espiatorio

La letteratura moderna, in particolare nei capolavori, tra gli altri, di Manzoni, Camus, Steinbeck presi in considerazione nel presente volume, con la capacità di iscriversi nelle coscienze che è propria della grande narrativa, ha posto sotto gli occhi e dentro la mente del lettore le crudeli devastazioni della antica e perversa dinamica alla base della costruzione del capro espiatorio e dei riti sacrificali. Specie di quelli che rivestano le pratiche persecutorie col manto legittimo e rispettabile del diritto e del processo penale. Dinamica che in René Girard ha trovato uno dei suoi massimi diagnosti e di cui il libro invita a fare dolente ma salutare esperienza, calandosi negli abissi più oscuri dell’animo umano, non senza riemergerne con possibili prospettive di giustizia e antidoti culturali e regolativi idonei a portare alla luce, contrastare o almeno contenere la formidabile spinta alla ricerca di vittime su cui illusoriamente scaricare colpe e nodi irrisolti da individui, istituzioni e collettività. Nella Storia della colonna infame di Alessandro Manzoni, da cui non a caso si è tratta ispirazione per il titolo del volume, il meccanismo del capro espiatorio trova il suo unico punto di rottura nella figura di Gasparo Migliavacca che, come Cristo in Girard, rifiuta di espandere la furia sacrificale evitando ulteriori chiamate di correità. Senza il suo esempio – come si legge nel libro – l’uomo sarebbe costretto a negare la Provvidenza o ad accu¬sarla, cioè si troverebbe vincolato all’interno di un dualismo incapace di dare una risposta al problema dell’esistenza del male.

Umbilical Cord Milking vs Delayed Cord Clamping and Associations with In-Hospital Outcomes among Extremely Premature&nbsp;Infants

ObjectiveTo compare in-hospital outcomes after umbilical cord milking vs delayed cord clamping among infants &lt;29&nbsp;weeks of gestation.Study designMulticenter retrospective study of infants born &lt;29&nbsp;weeks of gestation from 2016 to 2018 without congenital anomalies who received active treatment at delivery and were exposed to umbilical cord milking or delayed cord clamping. The primary outcome was mortality or severe (grade III or IV) intraventricular hemorrhage (IVH) by 36&nbsp;weeks of postmenstrual age (PMA). Secondary outcomes assessed at 36&nbsp;weeks of PMA were mortality, severe IVH, any IVH or mortality, and a composite of mortality or major morbidity. Outcomes were assessed using multivariable regression, incorporating mortality risk factors identified a priori, confounders, and center. A prespecified, exploratory analysis evaluated severe IVH in 2 gestational age strata, 22-246/7 and 25-286/7&nbsp;weeks.ResultsAmong 1834 infants, 23.6% were exposed to umbilical cord milking and 76.4% to delayed cord clamping. The primary outcome, mortality or severe IVH, occurred in 21.1% of infants: 28.3% exposed to umbilical cord milking and 19.1% exposed to delayed cord clamping, with an aOR that was similar between groups (aOR 1.45, 95% CI 0.93, 2.26). Infants exposed to umbilical cord milking had higher odds of severe IVH (19.8% umbilical cord milking vs 11.8% delayed cord clamping, aOR 1.70 95% CI 1.20, 2.43), as did the 25-286/7&nbsp;week stratum (14.8% umbilical cord milking vs 7.4% delayed cord clamping, aOR 1.89 95% CI 1.22, 2.95). Other secondary outcomes were similar between groups.ConclusionsThis analysis of extremely preterm infants suggests that delayed cord clamping is the preferred practice for placental transfusion, as umbilical cord milking exposure was associated with an increase in the adverse outcome of severe IVH.Trial registrationClinicalTrials.gov: NCT00063063

Admission Temperature and Associated Mortality and Morbidity among Moderately and Extremely Preterm Infants

ObjectiveTo evaluate the temperature distribution among moderately preterm (MPT, 29-33 weeks) and extremely preterm (EPT, &lt;29 weeks) infants upon neonatal intensive care unit (NICU) admission in 2012-2013, the change in admission temperature distribution for EPT infants between 2002-2003 and 2012-2013, and associations between admission temperature and mortality and morbidity for both MPT and EPT infants.Study designProspectively collected data from 18 centers in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network were used to examine NICU admission temperature of inborn MPT and EPT infants. Associations between admission temperature and mortality and morbidity were determined by multivariable logistic regression. EPT infants from 2002-2003 and 2012-2013 were compared.ResultsMPT and EPT cohorts consisted of 5818 and 3213 infants, respectively. The distribution of admission temperatures differed between the MPT vs EPT (P &lt; .01), including the percentage &lt;36.5°C (38.6% vs 40.9%), 36.5°C-37.5°C (57.3% vs 52.9%), and &gt;37.5°C (4.2% vs 6.2%). For EPT infants in 2012-2013 compared with 2002-2003, the percentage of temperatures between 36.5°C and 37.5°C more than doubled and the percentage of temperatures &gt;37.5°C more than tripled. Admission temperature was inversely associated with in-hospital mortality.ConclusionsLow and high admission temperatures are more frequent among EPT than MPT infants. Compared with a decade earlier, fewer EPT infants experience low admission temperatures but more have elevated temperatures. In spite of a change in distribution of NICU admission temperature, an inverse association between temperature and mortality risk persists
