Objectives. To investigate the obstetrical management of cancer in pregnancy and to determine adverse pregnancy and neonatal outcomes. Design. A register-based nationwide historical prospective cohort study. Setting and population. We assessed all pregnancies (N = 4,071,848) in Denmark from 1 January 1973 to 31 December 2018. Methods. We linked data on maternal cancer, obstetrical, and neonatal outcomes. Exposure was defined as pregnancies exposed to maternal cancer (n = 1,068). The control group comprised pregnancies without cancer. The groups were compared using logistic regression analysis and adjusted for potential confounders. Main outcome Measures. The primary outcome was the iatrogenic termination of the pregnancy (induced abortions/labor induction or elective caesarean section). Secondary outcomes were adverse neonatal outcomes. Results. More women with cancer in pregnancy, as compared to the control group, experienced first-trimester induced abortion; adjusted odds ratio (aOR) 3.7 (95% CI 2.8─4.7), second-trimester abortion; aOR 9.0 (6.4─12.6), iatrogenic preterm delivery; aOR 10.9 (8.1─14.7), and iatrogenic delivery below 32 gestational weeks; aOR 16.5 (8.5─32.2). Neonates born to mothers with cancer in pregnancy had a higher risk of respiratory distress syndrome; aOR 1.5 (1.2─2.0), but not of low birth weight; aOR 0.6 (0.4─0.8), admission to neonatal intensive care unit more than seven days; aOR 1.4 (1.1─1.9), neonatal infection; aOR 0.9 (0.5─1.5) nor neonatal mortality; aOR1.3 (0.6─2.6). Conclusion. Cancer in pregnancy implies an increased risk of iatrogenic termination of pregnancy and iatrogenic premature birth. Neonates born to mothers with cancer in pregnancy had no increased risk of severe adverse neonatal outcomes.

IntroductionRecent evidence from the USA and Nordic countries suggests a possible association between psychostimulant use during gestation and adverse pregnancy and birth outcomes. Objectives and ApproachWe employed a distributed cohort analysis using linked administrative data for women who gave birth in New South Wales (NSW; Australia) and Ontario (Canada), whereby a common protocol was implemented separately in each jurisdiction. The study population comprised women who were hospitalized for a singleton delivery over an 8 (NSW) and 4 (Ontario) year period, respectively, with the NSW cohort restricted to social security beneficiaries. Psychostimulant exposure was defined as at least one dispensing of methylphenidate, amphetamine, dextroamphetamine or lisdexamfetamine during pregnancy. We examined the risk of maternal and neonatal outcomes among psychostimulant exposed mothers compared with unexposed mothers. ResultsThere were 140,356 eligible deliveries in NSW and 449,499 in Ontario during the respective study periods. Fewer than 1% of these pregnancies were exposed to psychostimulants during gestation, although use was higher in Ontario (0.30% vs 0.11% in NSW). Preliminary unadjusted analyses indicated possible associations between psychostimulant use in pregnancy and higher risks of pre-term birth (relative risk [RR] 1.7, 95% confidence interval [CI] 1.4-2.0 (Ontario); RR 1.8, 95% CI 1.2-2.6 (NSW)) and pre-eclampsia (RR 2.0, 95% CI 1.5-2.6 (Ontario); RR 2.0, 95% CI 1.2-3.5 (NSW)). Similarly, psychostimulant use was associated with higher risks of low birthweight (RR 1.6, 95% CI 1.3-1.9 (Ontario); RR 2.0, 95% CI 1.3-3.0 (NSW)) and admission to neonatal intensive care (RR 2.1, 95% CI 1.9-2.3 (Ontario); RR 1.5, 95% CI 1.1-1.9 (NSW)). Conclusion / ImplicationsUnadjusted analyses indicate an increased risk of adverse maternal and birth outcomes associated with psychostimulant exposure during pregnancy, potentially representing a placental effect. We are currently refining the analyses, employing propensity score methods to adjust for confounding.

Introduction Assessing the risk factors for and consequences of infection with SARS-CoV-2 during pregnancy is essential to guide clinical guidelines and care. Previous studies on the influence of SARS-CoV-2 infection in pregnancy have been among hospitalised patients, which may have exaggerated risk estimates of severe outcomes because all cases of SARS-CoV-2 infection in the pregnant population were not included. The objectives of this study were to identify risk factors for and outcomes after SARS-CoV-2 infection in pregnancy independent of severity of infection in a universally tested population, and to identify risk factors for and outcomes after severe infection requiring hospital admission. Material and Methods This was a prospective population-based cohort study in Denmark using data from the Danish National Patient Register and Danish Microbiology Database and prospectively registered data from medical records. We included all pregnancies between March 1 and October 31, 2020 and compared women with a positive SARS-CoV-2 test during pregnancy to non-infected pregnant women. Cases of SARS-CoV-2 infection in pregnancy were both identified prospectively and through register linkage to secure that all cases were identified and that cases were pregnant during infection. Main outcome measures were pregnancy, delivery, maternal, and neonatal outcomes. Severe infection was defined as hospital admission due to COVID-19. Results Among 82 682 pregnancies, 418 women had SARS-CoV-2 infection during pregnancy, corresponding to an incidence of 5.1 per 1000 pregnancies, 23 (5.5%) of which required hospital admission due to COVID-19. Risk factors for infection were asthma (OR 2.19 [1.41-3.41]) and being foreign born (OR 2.12 [1.70-2.64]). Risk factors for hospital admission due to COVID-19 included obesity (OR 2.74 [1.00-7.51]), smoking (OR 4.69 [1.58-13.90]), infection after gestational age (GA) 22 weeks (GA 22-27 weeks: OR 3.77 [1.16-12.29]; GA 28-36 weeks: OR 4.76 [1.60-14.12]) and having asthma (OR 4.53 [1.39-14.79]). We found no difference in any obstetric or neonatal outcomes. Conclusions Only 1 in 20 women with SARS-CoV-2 infection during pregnancy require admission to hospital due to COVID-19. And severe outcomes of SARS-CoV-2 infection in pregnancy are rare.

Background: Both anaemia and high haemoglobin in pregnancy are associated with adverse pregnancy outcomes including foetal growth restriction. The objective of this study was to investigate the associations between maternal haemoglobin in pregnancy and trajectories of length/height and weight from birth through childhood. Methods: Data from 7,597 singleton pregnancies in the Avon Longitudinal Study of Parents and Children (ALSPAC), an ongoing, prospective, UK population-based pregnancy cohort study were used. We examined associations between maternal haemoglobin (overall pregnancy and trimester specific) and offspring length and weight at birth, as well as trajectories of height and weight gain from birth to age 10 years derived from multilevel models. Results: Mean pregnancy haemoglobin was 11.61 g/dL (SD 1.12). For each 1g/dL higher mean overall pregnancy haemoglobin, offspring were on average -0.30 cm shorter (95%CI: -0.35, -0.24, p <0.001), and -97.7 g lighter (95%CI: -110.42, -84.93, p <0.001) at birth when adjusting for potential confounders. Trimester specific inverse associations with birth length and weight were strongest for third trimester haemoglobin. There was evidence of a positive association between maternal haemoglobin levels and offspring height gain up to the age of one year and no strong evidence of associations between pregnancy haemoglobin and childhood weight gain. Conclusions: In high income countries, higher maternal haemoglobin in pregnancy may be a concern, as well as anaemia. Further studies are needed to define ‘high’ haemoglobin in pregnancy and whether monitoring of women with high pregnancy haemoglobin is warranted.

Abstract Background To examine association between gestational weight gain (GWG) in women with gestational diabetes mellitus (GDM) and adverse pregnancy outcomes (APOs). Methods This retrospective cohort study enrolled women with GDM who delivered at 2010–2020 in Changzhou, Jiangsu. Total GWG, rates of GWG in second trimester and third trimesters were stratified into three categories according to IOM guidelines: within, below, and above IOM guidelines. Univariable and multivariable logistic regression analyses were used. Results Overall, 1606 women with GDM fulfilled inclusion criteria. Compared with within IOM guidelines and after adjusting for confounders, total GWG above IOM guidelines in pregnancy was associated with an increased odds of caesarean delivery [adjusted odds ratio (aOR) = 1.34, 95% confidence interval (CI): 1.04–1.72], hypertensive disorders of pregnancy (HDP) (aOR = 2.00, 1.28–3.12), preeclampsia (aOR = 2.06, 1.01–3.12), macrosomia (aOR = 1.55, 1.13–2.13) and large for gestational age (LGA) (aOR = 2.82, 1.94–3.23), and a decreased odds of premature rupture of membrane (PROM) (aOR = 0.46, 0.36–0.60) and preterm birth (aOR = 0.35, 0.26–0.44); total GWG below IOM guidelines in pregnancy was associated with an increased risk of preterm birth (aOR = 1.96, 1.44–2.66), small for gestational age (SGA) (aOR = 1.32, 1.11–1.50) and a decreased odds of macrosomia (aOR = 0.35, 0.23–0.53) and LGA (aOR = 0.54, 0.42–0.72). Further, in both second and third trimesters of pregnancy, rates of GWG above IOM guidelines was found to be associated with a high odds of HDP (aOR = 2.55, 1.86–3.38; aOR = 1.93, 1.08–2.98), preeclampsia (aOR = 2.28, 1.21–3.81; aOR = 2.17, 1.35–4.37), macrosomia (aOR = 1.20, 1.02–1.82; aOR = 2.02, 1.51–2.64) and LGA (aOR = 1.42, 1.24–1.97; aOR = 1.79, 1.51–2.54). Rates of GWG above IOM guidelines in third trimester of pregnancy also increased odds of caesarean delivery (aOR = 1.48, 1.16–2.34) when compared with within IOM guidelines. While rates of GWG below IOM guidelines in both second and third trimesters of pregnancy was associated with a decreased odds of macrosomia (aOR = 0.66, 95% CI: 0.52–0.78; aOR = 0.52, 0.39–0.63) and LGA(aOR = 0.71, 0.51–0.82; aOR = 0.67, 0.55–0.79). In addition, rate of GWG below IOM guidelines in third trimester of pregnancy was associated with an increased odds of preterm birth (aOR = 1.52, 1.12–2.05) and SGA (aOR = 1.21, 1.10–1.69). Conclusion GWG, outside IOM guidelines has increased risks of APOs among women with GDM, implying that careful surveillance for GWG during different stages of pregnancy is warranted.
