Vacuum-assisted delivery is associated with late-onset asthma

ALLERGY, Issue 10 2009
L. Keski-Nisula
Background:, Perinatal factors during delivery might modulate fetal immunological development and thereby be associated with the development of allergic diseases and asthma later. Methods:, Perinatal data was recorded during pregnancy and at the time of delivery in regard to 5823 children who were born in Northern Finland in 1985,1986. Data from self-administered questionnaires were available at the ages of 7 and 15,16 years and skin prick tests for four main allergens were carried out at the age of 15,16 years. Only singletons delivered by the vaginal route were analyzed. Results:, There was a higher prevalence of doctor-diagnosed asthma at any time of life among children who were delivered by vacuum extraction (RR 1.80, 95% CI 1.27,2.56; P < 0.001) in comparison with spontaneously delivered children. In particular, this risk was increased as regards late-onset asthma (RR 2.41, 95% CI 1.52,3.81; P < 0.001). Perinatal effects had less impact on the development of other asthma, atopy or hay fever. Conclusions:, The delivery by vacuum extraction had significant impact on the development of late-onset asthma compared with spontaneously delivered children. [source]

Aspberg S, Dahlquist G, Kahan T, Källén B. Confirmed association between neonatal phototherapy or neonatal icterus and risk of childhood asthma. Pediatr Allergy Immunol 2010: 21: e733,e739. © 2010 John Wiley & Sons A/S We have previously demonstrated an association between neonatal phototherapy and/or neonatal icterus and risk of hospitalization for childhood asthma. This study included children who were prescribed anti-asthmatic medication on a population basis to study exposures during the foetal and neonatal period and risk of childhood asthma. The Swedish Medical Birth Register was linked to the Swedish Prescribed Drug Register. Perinatal data for singleton children who were prescribed anti-asthmatic medication (n = 61 256) were compared with corresponding data for all singleton children born in Sweden from 1 January 1990 to 30 June 2003 and surviving to 1 July 2005 (n = 1 338 319). Mantel,Haenszel's odds ratios were calculated after adjustment for various known confounders. Being the first-born child, maternal age above 44 yr, involuntary childlessness for more than 1 yr, maternal smoking during pregnancy, maternal diabetes mellitus of any kind, pre-eclampsia, caesarean section, and instrumental vaginal delivery were all associated with an increased prescription of anti-asthmatic medication during childhood. Preterm birth, low birth weight, being small for gestational age, respiratory problems, mechanical ventilation, and sepsis and/or pneumonia were also associated with increased drug prescriptions. Neonatal phototherapy and/or icterus were risk determinants for children who developed asthma before the age of 12. After controlling for confounders, the odds ratio for phototherapy and/or icterus remained at 1.30 (95% confidence interval 1.16,1.47). In conclusion, this large population-based study confirms an association between some maternal and perinatal factors and childhood asthma, including neonatal phototherapy and/or icterus. [source]

Hypertension during pregnancy in South Australia, Part 2: Risk factors for adverse maternal and/or perinatal outcome , results of multivariable analysis

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 5 2004
Sophie A. VREEBURG
Abstract Objective:, To identify factors associated with adverse pregnancy outcomes among women with hypertension during pregnancy Design:, A population-based retrospective multivariable analysis using the South Australian perinatal data collection. Methods:, Perinatal data on 70 386 singleton births in 1998,2001 were used in multivariable analyses on three groups: all women combined, all hypertensive women and women with pregnancy hypertension only, in order to identify independent risk factors for requirement for level II/III care, preterm birth, small for gestational age (SGA) birth and maternal length of stay greater than 7 days. Results:, The risks for the four morbidities were all increased among women with hypertension compared with normotensive women. Those with pre-existing hypertension had the lowest risk (with odds ratios (OR) 1.26,2.90). Pregnancy hypertension held the intermediate position (OR 1.52,5.70), while superimposed pre-eclampsia was associated with the highest risk (OR 2.00,8.75). Among women with hypertension, Aboriginality, older maternal age, nulliparity and pre-existing or gestational diabetes increased the risk for level II/III nursery care, preterm birth and prolonged hospital stay. Smokers had shorter stays, which may be related to their decreased risk of having a Caesarean section or operative vaginal delivery. Asian women, Aboriginal women, smokers and unemployed women had an increased risk for having an SGA baby, while women with pre-existing or gestational diabetes had a reduced risk. Conclusions:, Among hypertensive pregnant women, nulliparity, older maternal age, Aboriginality, unemployment and diabetes are independent risk factors for one or more major adverse pregnancy outcomes. Smoking does not always worsen the outcome for hypertensive women except for SGA births. [source]

Safe reduction in administration of naloxone to newborn infants: An observational study

ACTA PAEDIATRICA, Issue 9 2006
Deborah Box
Abstract Background: Naloxone, a specific opiate antagonist, is widely used during neonatal resuscitation to reverse possible opiate-induced respiratory depression. Aim: To determine the frequency with which naloxone is administered when resuscitation guidelines are conscientiously followed and to document any effect on respiratory morbidity. Methods: Perinatal data including naloxone administration and respiratory morbidity were collected retrospectively, and compared with prospectively collected data following the introduction of "Good Practice" guidelines. Results: There were 500 deliveries in the retrospective arm of the study and 1000 deliveries in the prospective arm. Although a similar proportion of women received opiates in labour in the two periods of study, there was a marked reduction in the use of naloxone when the guidelines were introduced (11% of opiate-exposed deliveries compared to 0.2%). There was no significant effect on respiratory morbidity with the change in practice. Conclusion: Naloxone is rarely needed to reverse the effects of opiates in newborn infants, and its use can be curtailed by following current resuscitation guidelines without increasing respiratory morbidity.

In-hospital mortality of newborn infants born before 33 weeks of gestation depends on the initial level of neonatal care: the EPIPAGE study

ACTA PAEDIATRICA, Issue 3 2003
JP Empana
Aim: To determine the relation between the level of initial neonatal care and in-hospital mortality of infants born before 33 wk of gestation in the era of surfactant therapy. Methods: A 1 y prospective population-based survey was conducted in the north of France, as part of the EPIPAGE (Epidemiologie des Petits Ages Gestationnels) survey. Perinatal data were recorded for 585 very premature newborns transferred to a neonatal intensive care unit in 1997. The relation between the level of the neonatal unit that provided care for the first consecutive 48 h and in-hospital mortality was assessed by multivariate logistic regression, and adjusted for perinatal data and initial disease severity, estimated by the Clinical Risk Index for Babies (CRIB). Results: The average gestational age (mean ± SD) was 31.6 ± 0.62 wk in level I, 30.7 ± 0.21 in level II, 29.9 ± 0.13 in non-teaching level III, and 29.0 ± 0.15 in the level III teaching unit (p < 0.0001). The mean in-hospital mortality rate was 8.4% and did not differ by level of care (ptrend= 0.17). After adjustment for perinatal data and CRIB, however, with the teaching unit as the reference, the risk of death was significantly higher in level I,II units [adjusted odds ratio (ORa) = 7.9, 95% confidence interval (95% CI) 2.2,29.1], but not in the non-teaching level III units (ORa = 0.8, 95% CI 0.3,2.1). Conclusion: In-hospital mortality in non-teaching level III units was similar to that in a teaching unit, but significantly higher in level I-level II units. Neonatal care of newborns delivered before 33 wk of gestation should initially occur in level III units. [source]

Brain abnormalities in extremely low gestational age infants: a Swedish population based MRI study

ACTA PAEDIATRICA, Issue 7 2007
Sandra Horsch
Abstract Aims: Brain abnormalities are common in preterm infants and can be reliably detected by magnetic resonance (MR) imaging at term equivalent age. The aim of the present study was to acquire population based data on brain abnormalities in extremely low gestational age (ELGA) infants from the Stockholm region and to correlate the MR findings to perinatal data, in order to identify risk factors. Methods: All infants with gestational age <27 weeks, born in the Stockholm region between January 2004 and August 2005, were scanned on a 1.5 T MR system at term equivalent age. Images were analysed using a previously established scoring system for grey and white matter abnormalities. Results: No or only mild white matter abnormalities were observed in 82% and moderate to severe white matter abnormalities in 18% of infants. The Clinical Risk Index for Babies (CRIB II) score, use of inotropes, the presence of high-grade intraventricular haemorrhages and posthaemorrhagic ventricular dilatation were associated with white matter abnormalities. Conclusion: The incidence of moderate to severe white matter abnormalities in a population-based cohort of ELGA infants from the Stockholm region was 18%. To examine the clinical relevance of these promising results, neurodevelopmental follow up at 30 month corrected age, is ongoing. [source]
