ABSTRACT
AIM: We evaluated a strict strategy that aimed to avoid fluctuations in glucose infusion rates (GIRs) and assessed the independent effects of maximal daily GIRs on the hyperglycaemia risk among extremely low birth weight (ELBW) infants receiving early enhanced parenteral nutrition. METHODS: This study comprised all ELBW infants admitted to the neonatal intensive care unit of Oslo University Hospital Rikshospitalet, Norway, before (2007-2009) and after (2012-2013) implementing a strict GIR strategy. Severe hyperglycaemia was defined as two consecutive blood glucose values over 12 mmol/L. Maximum daily GIRs (mg/kg/min) were categorised into low (<5.1), intermediate (5.1-7.0) or high (>7.0). Mixed effects logistic regression modelling for repeated measurements was applied to investigate independent determinants of hyperglycaemia. RESULTS: We included 1293 treatment days for 195 infants. The maximum daily GIR decreased (6.3 versus 5.8 mg/kg/min), while mean daily glucose and energy intakes were maintained in the post-strategy period. The prevalence of severe hyperglycaemia (48% versus 23%), insulin use (39% versus 16%) and mortality (26% versus 10%) fell. Intermediate GIR (odds ratio 2.11) and high GIR (odds ratio 2.85) were significant independent predictors of severe hyperglycaemia compared to low GIR. CONCLUSION: A strict GIR strategy reduced the risk of severe hyperglycaemia and adverse outcomes.

Cord blood insulin-like growth factor-1 (IGF-1) concentrations are lower in preeclamptic (PE) than normotensive (NT) pregnancies. PE offspring have increased risk of cardiovascular disease and decreased risk of some cancers including breast. We examined the effects of PE exposure in utero, infant feeding and childhood diet at 3-5 years on IGF-1 and breast development in 194 female offspring who were followed from birth until follow-ups at 10.8 and 12.9 years. Diet was not associated with serum IGF-1 levels at 10.8 years. PE exposure was associated with reduced odds of thelarche at 10.8 years only among exclusively breastfed girls. Milk, butter and ice cream consumption at 3-5 years was inversely related to the OR of breast development at 10.8 years. Child's weight and maternal overweight were positively associated with breast development at 10.8 years; child's height and weight were positively associated with breast development at 12.9 years.

BACKGROUND: The development of allergic sensitization and allergic disease may be related to factors during intrauterine life, but the role of maternal preeclampsia is not known.We studied if maternal preeclampsia is associated with long-term allergic sensitization, allergic rhinoconjunctivitis, atopic dermatitis, asthma and with altered lung function in late childhood. METHODS: 617 children participated in a 1:2 matched and controlled historical cohort study; 230 born after preeclamptic pregnancies and 387 born after normotensive pregnancies. Specific IgE in serum and lung function were measured at the age of 12.8 years and questionnaires on maternal and adolescent data were completed at the ages of 10.8 years (girls) and 11.8 years (boys), and at 12.8 years (both genders). The association between birth after preeclampsia and the main outcome measures allergic sensitization, allergic rhinoconjunctivitis, atopic dermatitis, asthma and lung function in late childhood were analysed with multiple regression analyses, including possible confounders. RESULTS: Severe maternal preeclampsia was associated with high level allergic sensitization (sum of specific IgE in serum ≥ 3.9 kU/l; the 25 percentile for all children being sensitized); odds ratio (OR): 3.79; 95% confidence interval (CI): (1.54, 9.32); p = 0.015 and with allergic rhinoconjunctivitis in offspring; OR: 2.22, 95% CI: (1.19, 4.14), p = 0.047. Preeclampsia was not associated with atopic dermatitis, asthma or altered lung function in late childhood. CONCLUSION: Maternal preeclampsia was associated with allergic sensitization and allergic rhinoconjunctivitis in offspring in late childhood, but not with other atopic diseases.

OBJECTIVE: To compare clinical signs of puberty onset in daughters of pre-eclampsia and normotensive pregnancies. DESIGN: Population based follow-up study. METHODS: In a cohort of 120 daughters of pre-eclampsia pregnancies and 203 daughters of pregnancies without pre-eclampsia, pubic hair growth and breast development were assessed at 11, 12 and 13 years of age by Tanner scores and by self-assessment. RESULTS: Compared to the normotensive group, pubic hair growth (pubarche) more often preceded breast development (thelarche) (risk ratio (RR) 2.3, 95% CI 1.3 to 4.1) and thelarche less often preceded pubarche (RR 0.8, 95% CI 0.7 to 1.0) in daughters of pre-eclampsia pregnancies. Adjustment for birth weight and body mass index in early adolescence did not substantially influence these results, but increasing severity of pre-eclampsia strengthened the differences. CONCLUSIONS: Pubarche tends to precede thelarche in daughters of pre-eclampsia pregnancies compared to daughters of normotensive pregnancies. This may reflect a stronger androgenic influence in daughters of pre-eclampsia pregnancies at the beginning of puberty.

AIMS: To compare cord blood concentrations of total adiponectin in the offspring of pregnancies with and without preeclampsia. METHODS: Using a Luminex analyzer, cord blood adiponectin was measured in 182 singleton pregnancies with preeclampsia and compared to adiponectin measured in 511 singleton pregnancies without preeclampsia. RESULTS: Adiponectin levels in cord blood increased with increasing gestational age, but overall, crude levels were similar in pregnancies with and without preeclampsia. However, in pregnancies with early delivery (weeks 32-36), and in pregnancies with delivery after spontaneous contractions, adiponectin levels were higher in the preeclampsia group. CONCLUSION: In preterm pregnancies and in pregnancies with spontaneous contractions, adiponectin levels in cord blood were higher in the preeclampsia group than in pregnancies without preeclampsia, maybe reflecting the need to optimize energy in preeclampsia.
