Abstract Objectives To examine pregnancy outcomes among births to women with idiopathic inflammatory myopathy (IIM) in relation to time of IIM diagnosis using population-based data. Methods This study used Swedish nationwide registers to identify all singleton births that occurred between 1973 and 2016 among women diagnosed with IIM between 1998 and 2016 and among women unexposed to IIM. We classified births according to the IIM status of the mother at time of delivery: post-IIM (n = 68), 1–3 years pre-IIM (n = 23), >3 years pre-IIM (n = 710) and unexposed to IIM (n = 4101). Multivariate regression models were used to estimate relative risks of adverse pregnancy outcomes in post-IIM births and pre-IIM births separately, in comparison with their non-IIM comparators. Results We found that post-IIM births had increased risks of caesarean section [adjusted relative risk (aRR) = 1.98; 95% CI: 1.08, 3.64], preterm birth (aRR = 3.35; 95% CI: 1.28, 8.73) and low birth weight (aRR = 5.69; 95% CI: 1.84, 17.55) compared with non-IIM comparators. We also noticed higher frequencies of caesarean section and instrumental delivery in 1–3 years pre-IIM births than in the non-IIM comparators. Conclusion Women who gave birth after IIM diagnosis had higher risks of caesarean section, preterm birth and low birth weight. These results further underline the importance of special care and close monitoring of women with IIM. Higher frequencies of caesarean section and instrumental delivery in pre-IIM births highlight the need for future research on the influence of subclinical features of IIM on pregnancy outcomes.

Abstract Background: Elderly mothers are increasingly in China. We are aims to explore whether association between pregnancy to delivery interval and adverse pregnancy outcomes is affected by maternal age. Methods: A population-based retrospective study was performed in Xiamen, China. Data were derived from the Medical Birth Registry of Xiamen from 2011 to 2018. Multivariable logistic regression was used to conduct multivariable analyses based on adjusting the factors to evaluate the effect of maternal age on pregnancy outcomes. Results: Among 77,859 pregnant women with specific age, gestational diabetes mellitus (GDM) risk were increased for women aged 40 years or older (42.9%; aRR, 3.84 (3.26-4.51); P < 0.001), but not for pregnant women aged less than 25 years (9.2%; aRR, 0.60 (0.54-0.68)). Increased cesarean, preterm birth, large-for-gestational age (LGA), and low birth weight risks were more pronounced for pregnant women aged 40 years or older (66.5%, 8.4%, 26.5%, and 6.7%, respectively; aRR, 3.77 (3.14-4.52), 1.26 (0.90-1.79), 1.31 (1.08-1.60), and 1.10 (0.74-1.65), respectively; all P < 0.001). Risk of Apgar < 7 at 5 minutes were increased for women < 25 years old compared with women 35 to 39 years old (0.2% vs. 0.1%; aRR, 2.05 (0.85-4.93) vs. 0.63 (0.14-2.86)). Conclusion: Advanced maternal age increased risk of adverse pregnancy outcomes. The risk ratio of GDM, cesarean, preterm birth, LGA, and low birth weight is higher, which suggests pregnant women should guard against related risk factors and choose an appropriate mode of production. Furthermore, pregnant women should choose an ideal age for pregnancy to make themselves and child healthy.

Background: Limited evidence is available on the safety and efficacy of antimicrobials during pregnancy, with even less according to the trimester of their use. Objective: This study aimed to evaluate the association between exposure to antibiotics therapy (AT) during pregnancy and short-term neonatal outcomes. Methods: We considered 773,237 deliveries that occurred between 2007–2017 in the Lombardy region of Italy. We evaluated the risk of neonatal outcomes among infants that were born to mothers who underwent AT during pregnancy. The odds ratios and the hazard ratios, with the 95% confidence intervals, were estimated respectively for early (first/second trimester) and late (third trimester) exposure. The propensity score was used to account for potential confounders. We also performed subgroup analysis for the class of AT. Results: We identified 132,024 and 76,921 singletons that were exposed to AT during early and late pregnancy, respectively. Infants born to mothers with early exposure had 17, 11, and 16% increased risk of preterm birth, low birth weight, and low Apgar score, respectively. Infants that were exposed in late pregnancy had 25, 11, and 13% increased risk of preterm birth, low birth weight, and low Apgar score, respectively. The results were consistent in the subgroup analysis. Conclusion: Our results suggested an increased risk of several neonatal outcomes in women exposed to ATs during pregnancy, albeit we were not able to assess to what extent the observed effects were due to the infection itself. To reduce the risk of neonatal outcomes, women that are prescribed AT during pregnancy should be closely monitored.

Adverse Pregnancy

Background and Aim: Advanced maternal age pregnancy could be referred to as pregnancy after 35 years or older. The prevalence of postponing pregnancies is increasing day by day worldwide. However, limited evidence was found on advanced maternal age pregnancy association with fetal adverse outcomes. The present study aimed to evaluate the frequency of advanced maternal age selected fetal adverse pregnancy outcomes. Place and Duration: Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera for duration of six months from November 2020 to April 2021. Materials and Methods: This single-centered retrospective study was conducted on 220 postpartum women in the study group (≥35 years) and 170 control group postpartum women (20-34 years) who delivered at Obstetrics & Gynaecology department of Alkhidmat Hospital Kohat and Qazi Hussain Ahmad Medical Complex, Nowshera after 28 gestational weeks. Individuals who met the inclusion criteria were enrolled and sampled based on randomized control sampling technique for both control and study groups. Data extraction checklist and pretested questionnaire were used for data collection from the maternal charts. Adverse pregnancy outcome and advanced maternal age was correlated adjusted relative risks and strength with a 95% confidence interval. SPSS version 20 was used for data analysis and considered p-value >0.05 as a statistical standard. Results: The adverse neonatal outcomes include low birth weight, preterm birth, and stillbirth with a prevalence 38 (17.4%), 46 (20.8%), and 31 (14.2%) respectively in the study group. In the control group, the incidence of low birth weight, preterm birth, and stillbirth was 21 (12.6%), 15 (14.6%) and 6 (3.5%) respectively. The stillbirth (ARR=3.16 95% CI (1.29–6.03) and preterm deliveries (ARR=2.71 95% CI (1.79–3.86) risk had significantly higher prevalence compared to control group advanced age pregnancy. Insignificance association was found between low birth weight and advanced maternal age. Conclusion: Stillbirth and preterm birth was the adverse fetal outcome significantly related with advanced maternal age pregnancy. There was no significant association between low birth weight and advanced maternal age. Keywords: Maternal age, Fetal Adverse Pregnancy Outcomes

Abstract Background and Aims In pregnancy and the postpartum period, complement gene variant mediated thrombotic microangiopathy (P-cTMA) can be life threatening for the mother and the child. We describe pregnancy and delivery outcomes of pregnancies a) before cTMA manifestation, b) complicated by P-cTMA, and c) after first manifestation of cTMA in such women. Method This study provides an update of patients enrolled in the Vienna TMA Cohort (VTC) as of January 2020. Demographic and clinical data were retrieved from the electronic and paper-based health care records of our institution and from the Austrian Mother-Child Health Passport. Pregnancy outcomes include live births (full term, moderate to late preterm, very preterm, extremely preterm) or deaths (miscarriage, foetal death, stillbirth, neonatal death). Among delivery outcome we ascertained spontaneous vaginal delivery; Caesarean section, gestational age, birth weight and birth weight categories, birth height, head circumference, Apgar scores, admission to a neonatal intensive care unit, and the presence of malformations. Results We recorded 58 pregnancies (41 live births/21 women, including one set of twins; 4 abortions and 1 stillbirth in 3 women without live births; 1 ongoing pregnancy; successful pregnancies: 40/57=70%) of 25 women (mean age [years] at first pregnancy 28.2±7.4, at cTMA manifestation 33.2±16.5). Currently 6 women have a kidney transplant and 4 have died (each death not related to pregnancy). Detailed pregnancy outcomes are shown in Figure 1. Table 1 indicates delivery outcomes of 41 live births. 6/8 neonates of pregnancies complicated by cTMA were female. Caesarean sections (female: 11/19, 58%; male: 9/24, 38%; p=0.11), preterm deliveries (female: 7/19, 37%; male: 5/24, 21%; p=0.09), and low birth weight (female: 6/19, 32%; male: 3/24, 13%; p=0.02) were more frequent among 43 pooled live births and stillbirths with known sex. Conclusion Overall, pregnancy and delivery outcomes were poor in pregnancies complicated by cTMA as compared to pregnancies before or after cTMA manifestation. The rate of Caesarean section, preterm delivery, and low birth weight was somewhat higher among female as compared to male neonates and stillbirths. Furthermore, neonatal female gender should be explored as risk factor for cTMA manifestation.

ObjectivesThis study aims to estimate the association between pregnancy-associated maternal cancers, diagnosed both prenatally and postnatally, and birth outcomes.DesignPopulation-based register study.SettingNational registers of Denmark and Sweden.ParticipantsA total of 5 523 365 children born in Denmark (1977–2008) and Sweden (1973–2006).Primary and secondary outcome measures: gestational age, birth weight, size for gestational age, Apgar score, caesarean section and sex were the outcomes of interest. ORs and relative risk ratios (RRR) with 95% CIs were estimated using logistic regression and multinomial logistic regression, respectively.ResultsIn this study, 2% of children were born to mothers with a diagnosis of cancer. Children whose mothers received a prenatal cancer diagnosis had higher risk of being born preterm (RRR: 1.77, 95% CI 1.64 to 1.90); low birth weight (RRR 1.84, 95% CI 1.69 to 2.01); low Apgar score (OR 1.36, 95% CI 1.20 to 1.56); and by caesarean section (OR: 1.69, 95% CI 1.59 to 1.80). Associations moved towards the null for analyses using postnatal diagnoses, but preterm birth (RRR: 1.13, 95% CI 1.09 to 1.17) and low birth weight (RRR: 1.14, 95% CI 1.09 to 1.18) remained statistically significant, while risk of caesarean section became so (OR: 0.95, 95% CI 0.91 to 0.98). Additionally, statistical significance was reached for large for gestational age (RRR: 1.06, 95% CI 1.01 to 1.11), high birth weight (RRR: 1.04, 95% CI 1.01 to 1.06) and caesarean section (OR: 0.95, 95% CI 0.91 to 0.98).ConclusionsResults suggest an association between pregnancy-associated cancers and adverse birth outcomes in the offspring. While this is strongest for prenatally diagnosed cancers, some smaller associations exist for postnatally diagnosed cancers, indicating that cancer itself could affect fetal development, or that cancer and adverse birth outcomes share risk factors. Future studies on maternal cancer during pregnancy should consider including some postnatal years in their exposure window.

Adverse Pregnancy

Introduction. Pregnancy at an advanced maternal age is defined as pregnancy at 35 years or older. Today, women postpone pregnancy due to different socioeconomic and personal reasons. However, there was limited evidence on fetal adverse outcomes’ association with pregnancy at an advanced maternal age in Ethiopia and particularly in the study area. This study was aimed at assessing the effect of pregnancy at an advanced age on selected neonatal adverse pregnancy outcomes in Debre Markos Referral Hospital, Ethiopia, 2019. Methods. Institution-based retrospective cohort study was conducted on 303 exposed (35 years and older) and 604 nonexposed (20–34 years old) immediate postpartum women who delivered at Debre Markos Referral Hospital after 28 weeks of gestation. All exposed women who fulfilled the inclusion criteria were sampled, and systematic random sampling was employed for those in the nonexposed group. The data were collected from 1st of July to 30th of December, 2019, by face-to-face interview and extraction from maternal chart using a structured questionnaire and data extraction checklist, respectively. Binary logistic regression (bivariate and multivariable) model was fitted, and wealth index was analyzed by principal component analysis. Adjusted relative risk with respect to 95% confidence interval was employed for the strength and directions of association between advanced maternal age and selected adverse pregnancy outcomes, respectively. P -value of <0.05 was used to declare statistical significance. Results. The incidence of adverse neonatal outcomes including stillbirth, preterm birth, and low birth weight in the advanced maternal age group was 13.2%, 19.8%, and 16.5%, respectively. The incidence of stillbirth, preterm birth, and low birth weight in the nonexposed group was 3.1%, 8.4%, and 12.4%, respectively. The advanced maternal age group had three times the risk of stillbirth compared with the nonexposed group (ARR = 3.14 95% CI (1.30–7.00)). The advanced maternal age group had 2.66 times the risk of delivering preterm fetus (ARR = 2.66 95% CI (1.81–3.77)) compared with the younger counterparts. Low birth weight was not significantly associated with pregnancy at an advanced maternal age. Conclusion. Fetal adverse outcomes including stillbirth and preterm birth were significantly associated with pregnancy at an advanced maternal age.

Adverse Pregnancy

Both preterm birth and low birth weight (LBW) represent major public health problems worldwide due to their association with the catastrophic effects of morbidity and mortality. Few data exist about such adverse pregnancy outcomes. The current study aimed to investigate the prevalence of and factors associated with preterm birth and LBW among mothers of children under two years in Abu Dhabi, United Arab Emirates. Data were collected in clinical and non-clinical settings across various geographical areas in Abu Dhabi. The data were analyzed using both descriptive and inferential statistics. A total of 1610 mother–child pairs were included in the current study. Preterm birth rate was 102 (6.3%) with a 95% confidence interval [CI] (6.1%, 6.5%) and the LBW rate was 151 (9.4%) with a 95% CI (9.3%, 9.5%). The mean (SD) of gestational age (GA) and birth weight at delivery was 39.1 (1.9) weeks and 3080.3 (518.6) grams, respectively. Factors that were positively associated with preterm birth were Arab mothers, maternal education level below secondary, caesarean section, and LBW. LBW was associated with female children, caesarean section (CS), first child order, and preterm birth. The current study highlighted the need for further interventional research to tackle these public health issues such as reducing the high CS rate and improving maternal education.
