Background Pregnant women are particularly vulnerable to severe infection from influenza resulting in poor neonatal outcomes. The majority of evidence relates to pandemic 2009 A/H1N1 influenza. The objective of this study was to describe the characteristics and outcomes of pregnant women hospitalised with seasonal influenza. Methods This national, prospective, observational cohort study used the UK Obstetric Surveillance System (UKOSS) to identify all pregnant women admitted to hospital between 01/11/2016 and 31/10/2018 with laboratory confirmed influenza at any gestation and up to two days after giving birth. These were compared to women admitted to give birth that did not have influenza. Baseline characteristics, immunization status, maternal and perinatal outcomes were compared. Results There were 405 women admitted to hospital with laboratory confirmed influenza in pregnancy: 2.7 per 10,000 maternities. Compared to 694 comparison women, women with influenza were less likely to be professionally employed (aOR 0.59, 95%CI 0.39–0.89) or immunised in the relevant season (aOR 0·59, 0·39–0·89) and more likely to have asthma (aOR 2.42, 1.30–4.49) or have had a previous pregnancy complication (aOR 2·47, 1·33–4·61). They were more likely to be admitted to intensive care (aOR 21.3, 2.78–163.1) and to have a cesarean birth (aOR 1·42, 1·02–1.98). Their babies were more likely to be admitted to neonatal intensive care (aOR 1.86, 1·01–3·42). Conclusions Immunization reduces the risk of hospitalisation with influenza in pregnancy which is associated with increased risk of morbidity for both the mother and baby. There is a continued need to increase awareness of safety and effectiveness of immunization in pregnancy and provision within antenatal care settings, especially for high-risk groups.

Background: Since the first confirmed case in December 2019, the data pertaining to the COVID-19 pandemic has been rapidly evolving. In current study, the relation of COVID-19 and its effect on pregnant women with hypertensive disorders in pregnancy, including symptoms and foetomaternal outcome were studied.Methods: Women with hypertensive disorders in pregnancy consecutively admitted for delivery and tested via nasopharyngeal swab for SARS-CoV-2 using reverse transcriptase polymerase chain reaction (RT-PCR) from 1 April 2020 to 30 September 2020 were included in the study.Results: In our study, 56 women having hypertensive disorders in pregnancy with COVID-19 infections delivering 60 babies (4 twins), 46.43% were in the age group of <25 years, 51.78 % were <37 weeks gestation. Delivery was by caesarean section in 76.78%. Out of these, 33.92% patients required ICU admission. 40% babies delivered had birth weight of <2.5 kg out of which 13.33% had IUGR and 26.66% were preterm. There was 13.33% stillbirth and 6.66% neonatal deaths. 4 maternal death has been reported.Conclusions: With the current data available it does not appear that pregnant women are at increased risk of severe infection than the general population, but clinicians should be aware of high-risk groups. Women will need to be monitored in their booking maternity units and should be transferred to centres with appropriate neonatal intensive care facilities for delivery. In pregnant women with COVID-19 infection, if maternal illness is not severe, the considerations should be based more on obstetric indications for delivery.

Background Cardiovascular symptoms in pregnancy may be a clue to psychological distress. We examined whether electrocardiogram testing in pregnant women is associated with an increased risk of subsequent postpartum depression. Methods We conducted a population-based cohort study of pregnant women who delivered in Ontario, Canada comparing women who received a prenatal ECG to women who did not. Results In total, 3,238,218 women gave birth during the 25-year study period of whom 157,352 (5%) received an electrocardiogram during prenatal care. Receiving an electrocardiogram test was associated with a one-third relative increase in the odds of postpartum depression (odds ratio 1.34; 95% confidence interval 1.29–1.39, p < 0.001). Conclusion The association between prenatal electrocardiogram testing and postpartum depression suggests a possible link of organic disease with mental illness, and emphasizes that cardiovascular symptoms may be a clinical clue to the presence of an underlying mood disorder.

Objective To determine if women who newly met criteria for stage 1 hypertension in early pregnancy were at increased risk for adverse perinatal outcomes compared with normotensive women. Study Design We conducted a retrospective cohort study of women who had prenatal care at a single institution and subsequently delivered a live infant between December 2017 and August 2019. Women with a singleton gestation who had at least two prenatal visits prior to 20 weeks of gestation were included. We excluded women with known chronic hypertension or other major maternal illness. Two groups were identified: (1) women newly diagnosed with stage 1 hypertension before 20 weeks of gestation (blood pressure [BP] 130–139/80–89 on at least two occasions) and (2) women with no known history of hypertension and normal BP (<130/80 mm Hg) before 20 weeks of gestation. The primary outcome was any hypertensive disorder of pregnancy; secondary outcomes were indicated preterm birth and small for gestational age. Generalized linear models were used to compare risk of adverse outcomes between the groups. Results Of the 1,630 women included in the analysis, 1,443 women were normotensive prior to 20 weeks of gestation and 187 women (11.5%) identified with stage 1 hypertension. Women with stage 1 hypertension were at significantly increased risk for any hypertensive disorder of pregnancy (adjusted risk ratio [aRR]: 1.86, 95% confidence interval [CI]: 1.12–3.04) and indicated preterm birth (aRR: 1.83, 95% CI: 1.12–3.02). Black women and obese women with stage 1 hypertension were at increased for hypertensive disorder of pregnancy compared with white women and nonobese women, respectively (aRR: 1.32, 95% CI: 1.11–1.57; aRR: 1.69, 95% CI: 1.39–2.06). Conclusion These results provide insight about the prevalence of stage 1 hypertension and inform future guidelines for diagnosis and management of hypertension in pregnancy. Future research is needed to assess potential interventions to mitigate risk. Key Points

BackgroundEvidence from the 2009 A/H1N1 influenza pandemic demonstrated that pregnant women are particularly vulnerable to infection and at an increased risk of death. Active data collection through the UK Obstetric Surveillance System (UKOSS) about women admitted to hospital during the 2009 A/H1N1 pandemic was used to inform ongoing clinical guidance regarding the use of antiviral treatment for pregnant women and demonstrated that, in addition to an increased risk of maternal morbidity, influenza infection in pregnancy is associated with poor perinatal outcomes, including an increased risk of stillbirth and preterm birth. This evidence influenced the decision to offer routine influenza immunisation to pregnant women. Even in a non-epidemic period, pregnant women continue to die from influenza.ObjectiveTo establish, and then to put into hibernation, the study mechanisms needed to mount a rapid investigation of the impact of pandemic influenza in pregnancy in the event of a newly emerging pandemic strain.DesignA new UKOSS cohort study was designed, based on the 2009–10 study, and following consultation with the Pandemic Flu Planning Group at the Royal College of Obstetricians and Gynaecologists and the UKOSS Steering Committee, to identify potential previously unanswered questions.SettingUK maternity units.ParticipantsAll pregnant women admitted to hospital with influenza in a future pandemic.Main outcome measuresManagement of pregnant women with influenza infection, intervention rates, treatment and pregnancy outcome for both the mother and fetus.ResultsThe study was designed and approved by the UKOSS Steering Committee and then placed into hibernation for activation in the event of an influenza pandemic.ConclusionsPregnant women, as a result of their changed immunological status, appear to be particularly susceptible to infection, including from influenza. The existence of the UKOSS enabled us to rapidly mount a study of pregnant women who were hospitalised with 2009 A/H1N1 influenza. Minor modifications to incorporate previously unanswered questions and our previous study enabled us to design, and then put into hibernation, a new study ready to investigate the impact and management of influenza in pregnancy, which is poised for activation in the event of a newly emerging pandemic strain. This will enable real-time data to be available on which to base rapid changes in clinical management as the as-yet-unforeseen pandemic unfolds. In the event of an influenza pandemic the study will be available to be immediately activated following expedited regulatory approvals.Trial registrationCurrent Controlled Trials ISRCTN44137563.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Background: Obesity is a state of excess adipose tissue mass. Body mass index (BMI) is a crucial predictor of nutritional status of pregnant women. High BMI may lead to various adverse maternal and perinatal outcomes. This study is designed to see the effect of maternal BMI on pregnancy outcome and perinatal outcome according to Asian standards.Methods: This is an institutional retrospective, descriptive study of 100 pregnant women conducted in the department of obstetrics and gynaecology of a rural tertiary centre Dr. PSIMS and RF, Chinaoutpalli, Gannavaram, Vijayawada, AP, India from June 2017 to July 2019.Results: It was observed that as BMI increased risk of complications increased like hypertension disorders in pregnancy, gestational diabetes mellitus, preterm labour. Also risk of macrosomia, operative delivery, Neonatal intensive care unit (NICU) admissions increased.Conclusions: As maternal BMI is a good predictor has strong correlation with pregnancy complications and outcomes, measures should be taken to motivate for pre pregnancy counselling regarding weight management and close surveillance in antenatal period to diagnose at the earliest any complications.

Background We conducted an overview of systematic reviews (SRs) summarizing the best evidence regarding the effect of COVID-19 on maternal and child health following Cochrane methods and PRISMA statement for reporting (PROSPERO-CRD42020208783). Methods We searched literature databases and COVID-19 research websites from January to October 2020. We selected relevant SRs reporting adequate search strategy, data synthesis, risk of bias assessment, and/or individual description of included studies describing COVID-19 and pregnancy outcomes. Pair of reviewers independently selected studies through COVIDENCE web-software, performed the data extraction, and assessed its quality through the AMSTAR-2 tool. Discrepancies were resolved by consensus. Each SR’s results were synthesized and for the most recent, relevant, comprehensive, and with the highest quality, by predefined criteria, we presented GRADE evidence tables. Results We included 66 SRs of observational studies out of 608 references retrieved and most (61/66) had "critically low" overall quality. We found a relatively low degree of primary study overlap across SRs. The most frequent COVID-19 clinical findings during pregnancy were fever (28–100%), mild respiratory symptoms (20–79%), raised C-reactive protein (28–96%), lymphopenia (34–80%), and pneumonia signs in diagnostic imaging (7–99%). The most frequent maternal outcomes were C-section (23–96%) and preterm delivery (14–64%). Most of their babies were asymptomatic (16–93%) or presented fever (0–50%), low birth weight (5–43%) or preterm delivery (2–69%). The odds ratio (OR) of receiving invasive ventilation for COVID-19 versus non-COVID-19 pregnant women was 1.88 (95% Confidence Interval [CI] 1.36–2.60) and the OR that their babies were admitted to neonatal intensive care unit was 3.13 (95%CI 2.05–4.78). The risk of congenital transmission or via breast milk was estimated to be low, but close contacts may carry risks. Conclusion This comprehensive overview supports that pregnant women with COVID-19 may be at increased risk of adverse pregnancy and birth outcomes and low risk of congenital transmission.

ObjectivesTo determine a 10-year trend of survival, morbidities and care practices, and predictors of in-hospital mortality in very preterm neonates (VPTN, gestation 22 to <32 weeks) in the Malaysian National Neonatal Registry.DesignRetrospective cohort study.Setting43 Malaysian neonatal intensive care units.Patients29 010 VPTN (without major malformations) admitted between 1 January 2009 and 31 December 2018.Main outcome measuresCare practices, survival, admission hypothermia (AH, <36.5°C), late-onset sepsis (LOS), pneumothorax, necrotising enterocolitis grade 2 or 3 (NEC), severe intraventricular haemorrhage (sIVH, grade 3 or 4) and bronchopulmonary dysplasia (BPD).ResultsDuring this 10-year period, there was increased use of antenatal steroid (ANS), lower segment caesarean section (LSCS) and early continuous positive airway pressure (eCPAP); but decreased use of surfactant therapy. Survival had increased from 72% to -83.9%. The following morbidities had decreased: LOS (from 27.9% to 7.1%), pneumothorax (from 6.0% to 2.7%), NEC (from 8.1% to 4.7%) and sIVH (from 12.2% to 7.5%). However, moderately severe AH (32.0°C–35.9°C) and BPD had increased. Multiple logistic regression analyses showed that lower birth weight, no ANS, no LSCS, admission to neonatal intensive care unit with <100 VPTN admissions/year, no surfactant therapy, no eCPAP, moderate and severe AH, LOS, pneumothorax, NEC and sIVH were significant predictors of mortality.ConclusionSurvival and major morbidities had improved modestly. Failure to use ANS, LSCS, eCPAP and surfactant therapy, and failure to prevent AH and LOS increased risk of mortality.

Background In the UK, the Alpha variant of SARS-CoV-2 became dominant in late 2020, rapidly succeeded by the Delta variant in May 2021. The aim of this study was to compare the impact of these variants on severity of maternal infection and perinatal outcomes within the time-periods in which they predominated. Methods This national, prospective cohort study collated data on hospitalised pregnant women with symptoms of confirmed SARS-CoV-2 infection and compared the severity of infection and perinatal outcomes across the Wildtype (01/03/20-30/11/20), Alpha (01/12/20-15/05/21) and Delta dominant periods (16/05/21-11/07/21), using multivariable logistic regression. Findings Of 3371 pregnant women, the proportion that experienced moderate to severe infection significantly increased between Wildtype and Alpha periods (24.4% vs. 35.8%; aOR1.75 95%CI 1.48-2.06), and between Alpha and Delta periods (35.8% vs. 45.0%; aOR1.53, 95%CI 1.07-2.17). Compared to the Wildtype period, symptomatic women admitted in the Alpha period were more likely to require respiratory support (27.2% vs. 20.3%, aOR1.39, 95%CI 1.13-1.78), have pneumonia (27.5% vs. 19.1%, aOR1.65, 95%CI 1.38-1.98) and be admitted to intensive care (11.3% vs. 7.7%, aOR1.61, 95%CI 1.24-2.10). Women admitted during the Delta period had further increased risk of pneumonia (36.8% vs. 27.5%, aOR1.64 95%CI 1.14-2.35). No fully vaccinated pregnant women were admitted between 01/02/2021 when vaccination data collection commenced and 11/07/2021. The proportion of women receiving pharmacological therapies for SARS-CoV-2 management was low, even in those critically ill. Interpretation SARS-CoV-2 infection during Alpha and Delta dominant periods was associated with more severe infection and worse pregnancy outcomes compared to the Wildtype infection, which itself increased risk compared to women without SARS-CoV-2 infection.1 Clinicians need to be aware and implement COVID-specific therapies in keeping with national guidance. Urgent action to tackle vaccine misinformation and policy change to prioritise uptake in pregnancy is essential. Funding National Institute for Health Research HS&DR Programme (11/46/12).

Objective: The aim of this study was to determine whether pregnant women who developed maternal hypoglycemia during the 75 g Oral Glucose Test (OGT) were at an increased risk for adverse obstetric and neonatal outcomes. Methods: This case-control study was conducted from computer-based medical records of women who delivered in a tertiary center between January 2015 and December 2018. OGT had been performed with 75 gr glucose for gestational diabetes screening at 24-28 weeks of gestation. The pregnants with 1st-hour blood glucose levels less than 90 mg/dl (low GT) were matched with normoglycemic patients according to age, body mass index (BMI), gravida and gestational weeks. Obstetric and neonatal outcomes were assessed. Results: Of the 1249 pregnant women included in the study, 62 (4.9%) were in the Low GT group. Admission to the neonatal intensive care unit (NICU) showed a rate of 3.48 increase in the Low GT group (95% confidence interval: 1.05-11.47, p=0.04). There was no difference between the two groups in the other obstetric and neonatal parameters such as: preeclampsia, preterm delivery, birth weight, and weight gained during pregnancy and the 5-minute Apgar scores adjusted for gestational age (SGA) of the fetus. Conclusion: Low 75 g OGT results are significantly associated with increased risk of neonatal intensive care unit (NICU) admissions.
