Obstetrical outcomes and maternal morbidities associated with COVID-19 in pregnant women in France: A national retrospective cohort study

Background To the best of our knowledge, no study has exhaustively evaluated the association between maternal morbidities and Coronavirus Disease 2019 (COVID-19) during the first wave of the pandemic in pregnant women. We investigated, in natural conceptions and assisted reproductive technique (ART) pregnancies, whether maternal morbidities were more frequent in pregnant women with COVID-19 diagnosis compared to pregnant women without COVID-19 diagnosis during the first wave of the COVID-19 pandemic. Methods and findings We conducted a retrospective analysis of prospectively collected data in a national cohort of all hospitalizations for births ≥22 weeks of gestation in France from January to June 2020 using the French national hospitalization database (PMSI). Pregnant women with COVID-19 were identified if they had been recorded in the database using the ICD-10 (International Classification of Disease) code for presence of a hospitalization for COVID-19. A total of 244,645 births were included, of which 874 (0.36%) in the COVID-19 group. Maternal morbidities and adverse obstetrical outcomes among those with or without COVID-19 were analyzed with a multivariable logistic regression model adjusted on patient characteristics. Among pregnant women, older age (31.1 (±5.9) years old versus 30.5 (±5.4) years old, respectively, p < 0.001), obesity (0.7% versus 0.3%, respectively, p < 0.001), multiple pregnancy (0.7% versus 0.4%, respectively, p < 0.001), and history of hypertension (0.9% versus 0.3%, respectively, p < 0.001) were more frequent with COVID-19 diagnosis. Active smoking (0.2% versus 0.4%, respectively, p < 0.001) and primiparity (0.3% versus 0.4%, respectively, p < 0.03) were less frequent with COVID-19 diagnosis. Frequency of ART conception was not different between those with and without COVID-19 diagnosis (p = 0.28). When compared to the non-COVID-19 group, women in the COVID-19 group had a higher frequency of admission to ICU (5.9% versus 0.1%, p < 0.001), mortality (0.2% versus 0.005%, p < 0.001), preeclampsia/eclampsia (4.8% versus 2.2%, p < 0.001), gestational hypertension (2.3% versus 1.3%, p < 0.03), postpartum hemorrhage (10.0% versus 5.7%, p < 0.001), preterm birth at <37 weeks of gestation (16.7% versus 7.1%, p < 0.001), <32 weeks of gestation (2.2% versus 0.8%, p < 0.001), <28 weeks of gestation (2.4% versus 0.8%, p < 0.001), induced preterm birth (5.4% versus 1.4%, p < 0.001), spontaneous preterm birth (11.3% versus 5.7%, p < 0.001), fetal distress (33.0% versus 26.0%, p < 0.001), and cesarean section (33.0% versus 20.2%, p < 0.001). Rates of pregnancy terminations ≥22 weeks of gestation, stillbirths, gestational diabetes, placenta praevia, and placenta abruption were not significantly different between the COVID-19 and non-COVID-19 groups. The number of venous thromboembolic events was too low to perform statistical analysis. A limitation of this study relies in the possibility that asymptomatic infected women were not systematically detected. Conclusions We observed an increased frequency of pregnant women with maternal morbidities and diagnosis of COVID-19 compared to pregnant women without COVID-19. It appears essential to be aware of this, notably in populations at known risk of developing a more severe form of infection or obstetrical morbidities and in order for obstetrical units to better inform pregnant women and provide the best care. Although causality cannot be determined from these associations, these results may be in line with recent recommendations in favor of vaccination for pregnant women.

Feasibility and Outcomes of “No-Look No-Touch” Laparoscopic Radical Trachelectomy for Early-Stage Cervical Cancer

Intraoperative tumor manipulation and dissemination may compromise the survival of women with early-stage cervical cancer who undergo laparoscopic surgery. This study aimed to examine survival and obstetrical outcomes related to laparoscopic radical trachelectomy (LRT) with a “no-look no-touch” technique in 40 women. This technique incorporates five measures to prevent tumor spillage and damage to the uterine artery perfusion. Five LRTs were aborted because of positive nodes or positive surgical margins. Compared with those of type III laparoscopic radical hysterectomy, the surgical outcomes of LRT in 35 patients were acceptable: operative time (380 min), estimated blood loss (140 mL), length of hospital stay (15 days), and lengths of excised parametrium and vagina. During follow-up (median, 41.3 months), the 5-year disease-free survival and overall survival were 95.0% (95% CI: 69.5–99.3%) and 100%, respectively. Of the nine patients (26%) who attempted pregnancy, seven conceived (nine pregnancies, 76%). Eight were delivered by term cesarean section, while one was miscarried in the first trimester. Our study suggests that the no-look no-touch technique may be effective in reducing the risk of recurrence and improving obstetrical outcomes during LRT for early-stage cervical cancer.

Level of adherence to vitamin D supplementation guidelines in an antenatal centre in Birmingham, UK, and its effect on biochemical and obstetrical outcomes: a single-centre cross-sectional study

ObjectivesA third of pregnant women in the UK are vitamin D deficient, which may confer deleterious consequences, including an increased risk of pre-eclampsia, gestational diabetes mellitus and intrauterine growth restriction. This study aims to determine the proportion of women that met National Institute for Health and Care Excellence (NICE) standards for vitamin D supplementation in pregnancy and compare biochemical and obstetrical outcomes according to supplementation status.Design and settingThis is a single-centre cross-sectional study in an antenatal centre in Birmingham, UK. Participants received a questionnaire regarding their experiences with vitamin D supplementation during their pregnancy with their general practitioner. Serum 25-hydroxyvitamin D and bone profile results were obtained during the same appointment and obstetrical outcomes were collected retrospectively once participants had delivered.Results41.8% of participants (n=61) received written and/or verbal advice about supplementation, (NICE standards=100%). 72.6% (n=106) had one or more risk factors for vitamin D deficiency, of which 38.7% (n=41, NICE standards=100%) were asked about supplementation. Among those asked, 85.4% (n=41, NICE standards=100%) received the correct dosage. Compared with the supplementation group, the non-supplementation group had offspring that were 1.40 cm (95% CI 0.01 to 2.80, p=0.04) longer at birth; which was significant after adjusting for confounding factors. No significant differences in any biochemical parameters were observed between supplementation categories (p>0.05).ConclusionsAdherence to NICE standards was suboptimal. This may be attributed to insufficient training for general practitioners on the importance of supplementation, causing them to underestimate the consequences of gestational vitamin D deficiency. Recommendations include implementing a mandatory screening tool to identify ‘at-risk’ women and providing more clinician training to ensure that supplementation during pregnancy is standard of care.
