Morbidity and mortality after anaesthesia in early life:results of the European prospective multicentre observational study, neonate and children aud…
2021
Background: Neonates and infants requiring anaesthesia are at risk of physiological instability and complications, but triggers for peri-anaesthetic interventions and associations with subsequent outcome are unknown. Methods: This prospective, observational study recruited patients up to 60 weeks' postmenstrual age undergoing anaesthesia for surgical or diagnostic procedures from 165 centres in 31 European countries between March 2016 and January 2017. The primary aim was to identify thresholds of pre-determined physiological variables that triggered a medical intervention. The secondary aims were to evaluate morbidities, mortality at 30 and 90 days, or both, and associations with critical …
Delayed vs Immediate Cord Clamping Changes Oxygen Saturation and Heart Rate Patterns in the First Minutes after Birth
2020
Objective To build arterial oxygen saturation (SpO2) and heart rate (HR) percentiles for the first 10 minutes after birth in term infants born after an uneventful gestation, vaginal delivery, and delayed cord clamping (DCC) for ≥60 seconds, and to compare our results with previous ones constructed after immediate cord clamping. Study design Preductal SpO2, HR, and timing of DCC immediately after complete fetal body expulsion were recorded. The pulse-oximeter was adjusted in the right wrist/hand and set at maximal intensity and measurements performed every 2 seconds. Results A total of 282 term newborn infants were included. The definitive data set comprised of 70 257 SpO2 and 79 746 HR meas…
A multi-generational study on low-dose BPA exposure in Wistar rats: Effects on maternal behavior, flavor intake and development
2012
Bisphenol A (BPA) is a common endocrine disruptor found as an environmental and food contaminant. It exerts both developmental and behavioral effects, mainly when exposure occurs in early life. The aim of this study was to determine the multi-generational effects of chronic, human-relevant low-dose exposure to BPA on development, maternal behavior and flavor preference in Wistar rats. BPA was orally administered at a daily dose of 5 mu g/kg body weight to FO pregnant dams from the first day of gestation (GD 1) until the last day of lactation (LD 21), and then to Fl offspring from weaning (PND 21) to adulthood (PND 100). F2 offspring were not exposed. Development and clinical signs of toxici…
Cry characteristics of 172 healthy 1-to 7-day-old infants.
2002
A total of 1,836 cry signals from 172 healthy babies, 1–7 days old, were analysed with sound spectrography. The mean values for the 8–15 cries from each infant were calculated and used for the statistical analyses. The mean duration of the cry signals was 1.4 ± 0.6 s. The mean fundamental frequency was 496 ± 95 cps (Hz). Fifty percent of the mean fundamental frequencies in the 8–15 cries analysed from each baby varied between 450 and 520 Hz. Of the children, 93% had cries with a mean fundamental frequency below 600 Hz. The mean value of the highest point of the fundamental frequency was 583 ± 151 Hz and of the lowest point 398 ± 75 Hz. The melody type had mainly a rising-falling contour, th…

Improvement of treatment adherence with growth hormone by easypod™ device: experience of an Italian centre
2018
Abstract Background One of the most important vulnerabilities falling the efficacy of recombinant human growth hormone (r-hGH) treatment is low adherence especially in young patients. This study was planned to describe the correlation between r-hGH treatment efficacy and adherence in real-life setting using easypod™. Methods Forty patients younger than 18 years, affected by a clinical condition in which r-hGH is available and treated with r-hGH easypod™, were enrolled in a retrospective, observational, real-world data, monocentric trial. The study design provided the retrospective collection of records collected by a questionnaire proposed to the patients and their parents and compared with…
Decreased prevalence of left-handedness among females with male co-twins: evidence suggesting prenatal testosterone transfer in humans?
2009
Studies of singletons suggest that right-handed individuals may have higher levels of testosterone than do left-handed individuals. Prenatal testosterone levels are hypothesised to be especially related to handedness formation. In humans, female members from opposite-sex twin pairs may experience elevated level of prenatal exposure to testosterone in their intra-uterine environment shared with a male. We tested for differences in rates of left-handedness/right-handedness in female twins from same-sex and opposite-sex twin pairs. Our sample consisted of 4736 subjects, about 70% of all Finnish twins born in 1983–1987, with information on measured pregnancy and birth related factors. Circulati…
Report on Intrauterine Drug Exposure During Second Trimester of Pregnancy in a Heroin-Associated Death
1999
A 17-year-old girl was found dead in a public toilet with fresh needle puncture marks. She was 18-20 weeks pregnant with a male fetus. Drug screening of her blood and urine indicated recent heroin use. Chronic drug use was confirmed by hair analysis. Amniotic fluid as well as fetal and maternal tissues and body fluids were analyzed by GC/MS and HPLC. All the fetal specimens were investigated, and the following levels of drugs were found: 6-monoacetyl-morphine (blood: 152 ng/g; amniotic fluid: 128 ng/g; brain: 140 ng/g; lung: 110 ng/g; liver: 2 ng/g; kidney: 40 ng/g), morphine (blood: 1360 ng/g; amniotic fluid: 604 ng/g; brain: 710 ng/g; lung: 1030 ng/g; liver: 2060 ng/g; kidney: 1100 ng/g),…
Human milk enhances antioxidant defenses against hydroxyl radical aggression in preterm infants
2008
Background: Preterm infants endowed with an immature antioxidant defense system are prone to oxidative stress. Hydroxyl radicals are very aggressive reactive oxygen species that lack specific antioxidants. These radicals cannot be measured directly, but oxidation byproducts of DNA or phenylalanine in urine are reliable markers of their activity. Human milk has a higher antioxidant capacity than formula. Objective: We hypothesized that oxidative stress associated with prematurity could be diminished by feeding human milk. Design: We recruited a cohort of stable preterm infants who lacked perinatal conditions associated with oxidative stress; were not receiving prooxidant or antioxidant drugs…
Is faster better? A randomised crossover study comparing algorithms for closed-loop automatic oxygen control
2019
ObjectiveClosed-loop automatic control (CLAC) of the fractional inspired oxygen (FiO2) improved oxygen administration to preterm infants on respiratory support. We investigated whether a revised CLAC algorithm (CLACfast, ≤2 FiO2 adjustments/min), compared with routine manual control (RMConly), increased the proportion of time with arterial haemoglobin oxygen saturation measured by pulse oximetry within prespecified target ranges (Target%) while not being inferior to the original algorithm (CLACslow: ≤0.3 FiO2 adjustments/min).DesignUnblinded randomised controlled crossover study comparing three modes of FiO2 control in random order for 8 hours each: RMC supported by CLACfast was compared wi…
