- BackgroundMetabolic acidosis, measured in arterial umbilical cord blood at birth, is the most accepted definition of birth asphyxia. The aim of the study was to investigate the rates of metabolic acidosis across the entire range of Apgar score values (0–10) at 1, 5, and 10 min in term infants.MethodsIn a population-based Swedish cohort of births between 2008 and 2013, we included 85,076 term (≥37 weeks) non-malformed infants with information from umbilical arterial blood gas analyses and complete information on Apgar scores (0–10) at 1, 5, and 10 min.ResultsRates of metabolic acidosis generally decreased with increasing Apgar score values. For Apgar score at 1 min, this decrease was consistent from Apgar score 0 (35%) to Apgar score 10 (0%). For Apgar scores at 5 and 10 min, the decrease was consistent for Apgar score values from 6 to 10.ConclusionAlthough there is a close association between Apgar score values and rates of metabolic acidosis, Apgar score is not and should not be used as a measure of birth asphyxia.

- To study the association between induction and outcome among two-parous women in uncomplicated pregnancies ≥ 41+3, stratified by first labour delivery mode and conditions present at first delivery. The Swedish Medical Birth Register was used to identify 58,964 uncomplicated singleton pregnancies among women with one previous birth between 1998 and 2014. Women with any registered pregnancy complications were excluded to minimise the risk for indication bias. The outcomes considered were emergency caesarean section (CS), and poor neonatal outcome (Apgar score <7 at 5 min, neonatal death, or meconium aspiration). Women who were induced at their second labour had higher emergency CS rates compared to women in spontaneously started deliveries (adjusted risk ratio, ARR: 2.11; 95% CI: 2.00-2.23). Low Apgar score was more common after induction compared to spontaneously started labours (1.0 vs. 0.7%) (ARR: 1.44; 95% CI: 1.18-1.77). Increased CS rates were also found when comparing induction at 41 + 3 to 41 + 6 weeks to labour at 42 weeks or more, regardless of labour start (ARR 1.39; 95% CI: 1.26-1.52). We found an increased risk of CS and poor neonatal outcome after second labour induction in prolonged pregnancies. The second labour vaginal success rate after induction was highly dependent, on first labour delivery mode, but also on diagnoses and conditions present at the first delivery.

- Objectives: Contemporary obstetrics has begun to appreciate the importance of diet in pregnancy, but guidelines are not based on robust data. The hypothesis that a whole grains diet improves pregnancy outcomes is tested in this study. We compared maternal and neonatal outcomes for a pregnancy diet containing 75% of total carbohydrates as refined grains with outcomes for a diet with 75% of total carbohydrates as whole grains. Methods: This was a randomized interventional study in a clinic population over the last 4-7 months of normal pregnancy with extensive compliance measures. Besides obstetrical and neonatal outcomes, anthropometric measurements were done. In addition to food frequency questionnaires (FFQs), total plasma alkyl resorcinols, a unique quantitative measure of whole grains, were used as a measure of whole grain consumption. Results: The data show effective compliance and no difference in outcomes between the diets with regard to maternal weight gain, birth weights, subcutaneous fat and glucose tolerance. Conclusions: Ensuring compliance to a proper pregnancy diet resulted in satisfactory weight gain and normal outcomes even when the proportion of whole grains consumed is only 25% of total carbohydrates. www.ClinicalTrials.gov NCT03232762, Effects of Diet on Pregnancy Outcome and Child Obesity.
