OBJECTIVE: To investigate the frequency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in parturient women, their partners, and their newborns and the association of such antibodies with obstetric and neonatal outcomes. METHODS: From April 4 to July 3, 2020, in a single university hospital in Denmark, all parturient women and their partners were invited to participate in the study, along with their newborns. Participating women and partners had a pharyngeal swab and a blood sample taken at admission; immediately after delivery, a blood sample was drawn from the umbilical cord. The swabs were analyzed for SARS-CoV-2 RNA by polymerase chain reaction, and the blood samples were analyzed for SARS-CoV-2 antibodies. Full medical history and obstetric and neonatal information were available. RESULTS: A total of 1,313 parturient women (72.5.% of all women admitted for delivery at the hospital in the study period), 1,188 partners, and 1,206 newborns participated in the study. The adjusted serologic prevalence was 2.6% in women and 3.5% in partners. Seventeen newborns had SARS-CoV-2 immunoglobulin G (IgG) antibodies, and none had immunoglobulin M antibodies. No associations between SARS-CoV-2 antibodies and obstetric or neonatal complications were found (eg, preterm birth, preeclampsia, cesarean delivery, Apgar score, low birth weight, umbilical arterial pH, need for continuous positive airway pressure, or neonatal admission), but statistical power to detect such differences was low. Full serologic data from 1,051 families showed an absolute risk of maternal infection of 39% if the partner had antibodies. CONCLUSION: We found no association between SARS-CoV-2 infection and obstetric or neonatal complications. Sixty-seven percent of newborns delivered by mothers with antibodies had SARS-CoV-2 IgG antibodies. A limitation of our study is that we lacked statistical power to detect small but potentially meaningful differences between those with and without evidence of infection.

Background Several viral infections are known to be harmful to the fetus in the first trimester of pregnancy and can cause increased nuchal translucency thickness and pregnancy loss. Currently, no evidence exists regarding possible effects of SARS-CoV-2 in first trimester pregnancies. Methods Cohort 1 included pregnant women with a double test taken between Feb. 17 and Apr. 23, 2020, during the SARS-CoV-2 epidemic peak in Denmark. The double test was taken as part of the first trimester risk assessment. Cohort 2 included women with a first trimester pregnancy loss before double test. Serum from the double test or from a blood sample, in case of pregnancy loss, was analyzed for SARS-CoV-2 antibodies. The results were correlated to the nuchal translucency thickness and the number of pregnancy losses. Results In total, 1,019 pregnant women with double test and 36 women with pregnancy loss participated in the study. Thirty (2.9%) women had SARS-CoV-2 antibodies in the serum from the double test. All women with pregnancy loss prior to the double test were negative for SARS-CoV-2 antibodies. There were no significant differences in nuchal translucency thickness for women testing positive (n=14) versus negative (p=0.20) or grey zone (n=16) versus negative (p=0.28). In total, 54 women experienced a pregnancy loss of whom two had grey zone or positive SARS-CoV-2 antibodies. Conclusion Maternal SARS-CoV-2 infection did not seem harmful in first trimester pregnancies. Infection had no effect on the nuchal translucency thickness and women with SARS-CoV-2 antibodies were not overrepresented among women with pregnancy loss.

Background: Only few studies have focused on serological testing for SARS-CoV-2 in pregnant women and no previous study has investigated the frequency in partners. The aim was to investigate the frequency and impact of SARS-CoV-2 in parturient women, their partners and newborns. Methods: From April 4th to July 3rd, 2020, all parturient women, their partners and newborns were invited to participate in the study. Participating women and partners had a pharyngeal swab and a blood sample taken at admission and immediately after delivery a blood sample was drawn from the umbilical cord. The swabs were analyzed for SARS-CoV-2 RNA by PCR and the blood samples were analyzed for SARS-CoV-2 antibodies. Full medical history, obstetric- and neonatal information were available. Results: A total of 1,361 parturient women, 1,236 partners and 1,342 newborns participated in the study. No associations between previous COVID-19 disease and obstetric- or neonatal complications were found. The adjusted serological prevalence was 2.9% in women and 3.8% in partners. The frequency of blood type A was significantly higher in women with antibodies compared to women without antibodies. 17 newborns had SARS-CoV-2 IgG antibodies, and none had IgM antibodies. Full serological data from 1,052 families showed an absolute risk of infection of 0.37 if the partner had antibodies. Only 55% of individuals with antibodies reported symptoms. Conclusion: This large prospective cohort study reports no association between COVID-19 and obstetric- or neonatal complications. The family pattern showed a substantial increase in absolute risk for women living with a partner with antibodies.

Background Postpartum haemorrhage is one of the leading causes of maternal mortality in low-income countries. Improving health workers' competencies in obstetric emergencies in low-income settings, has been recognized as an important factor in preventing maternal mortality and morbidity. mHealth interventions in maternal and newborn health care has shown the potential to improve health service delivery. Strong study designs such as randomized controlled trials are missing to estimate the effectiveness of the mHealth interventions. Methods Between August 2013 and August 2014, 70 health facilities in West Wollega Region, Ethiopia were included and randomized to intervention or control in a cluster randomized controlled trial. At intervention facilities birth attendants were provided with a smartphone with the SDA installed. Of 176 midwives and “health extension workers,” 130 completed at 12 months follow-up. At baseline and after 6- and 12-months participants were assessed. Knowledge was tested by a Key Feature Questionnaire, skills by an Objective Structured Assessment of Technical Skills in a structured role-play scenario. Results Baseline skills scores were low and comparable with a median of 12/100 in the intervention and the control group. After 6 months skills had doubled in the intervention group (adjusted mean difference 29.6; 95% CI 24.2–35.1 compared to 1·8; 95% CI – 2.7 to 6.3 in the control group). At 12 months skills had further improved in the intervention group (adjusted mean difference 13.3; 95% CI 8.3–18.3 compared to 3.1; 95% CI – 1.0 to 7.3 in the control group). Knowledge scores also significantly improved in the intervention group compared to the control (adjusted mean difference after 12 months 8.5; 95% CI 2.0–15.0). Conclusion The Safe Delivery App more than doubled clinical skills for managing postpartum haemorrhage among birth attendants making it an attractive tool to reduce maternal mortality.

AbstractIntroductionDietary changes in pregnancy may be a marker for later pregnancy complications. This study aims to investigate if there is a difference in the proportion of women who experience specific pregnancy related complications vs those who do not, in relation to specific dietary changes made during pregnancy.Materials and methodsWithin the Danish National Birth Cohort, established during 1996 and 2003, dietary changes from 70,053 pregnancies were assessed in gestational week (GW) 25 using two open-ended questions (q1 and q2) on aversions or preferences appended to a 350-item food frequency questionnaire; “did you stop(q1) or start(q2) consuming a specific food during pregnancy?” After restricting to the firstborn child enrolled, born at term (GW 37 + 1–42 + 0) with a birth weight between 1,0 and 6,0 kilograms, excluding multiple pregnancies and abortions, dietary change answers from 55,087 women were coded into 65 food groups. Using chi-X2 test, we compared proportions of women with and without three pregnancy complications: preeclampsia (obtained via linkage to the Danish National Patient Registry), children born small-for-gestational-age (SGA, < 10th percentile) or children born large-for-gestational-age (LGA, > 90th percentile) with respect to their answers about aversions/preferences.ResultsAmong the 55,087 women, 49% and 31% reported any aversions or preferences, respectively. Most frequent were women reporting aversion of alcohol (22.7%) or coffee (15.4%), and preference of milk products (7.9%) or fruits and berries (6.9%), which were selected a priori for analyses. 8.3% of women experienced preeclampsia, and 9.7% and 9.3% of children were characterizes as being born SGA or LGA, respectively. Compared with no dietary change: avoiding alcohol or coffee was associated with smaller proportion of SGA (10% vs 8%, p = 0.01 and 10% vs 7%, p < 0.0001) and avoiding coffee was also associated with greater proportion of LGA (9% vs 11%, p = 0.01). Increasing milk products or fruit/berries was associated with smaller proportions of SGA (14% vs 10% in both conditions, p < 0.009). No significant association in reported aversions/preferences was detected for preeclampsia.DiscussionThe results lead to additional questions, such as “Why do women who increase consumption of milk products or fruits/berries tend to deliver SGA infants and why do women who stop drinking coffee tend to deliver LGA infants?” The presented results and further analyses are important to public health initiatives for optimizing maternal nutrition with long-term influence to offspring Health.
