Inflammatory markers in relation to maternal lifestyle and adverse pregnancy outcomes in twin pregnancies.

It is well known that inflammatory markers play an important role in the development and maintenance of healthy pregnancies. However, the literature regarding inflammation in relation to lifestyle and adverse pregnancy outcomes in twin pregnancies is remarkably uncovered. Therefore, this study aimed at evaluating the concentration of inflammatory markers in dried capillary blood spot samples from 523 women with twin pregnancies, included at a median gestational age of 21+1 weeks. The relationship between inflammatory markers and maternal lifestyle (current smoking status and pre-pregnancy body mass index) in addition to adverse pregnancy outcomes (preeclampsia, gestational diabetes mellitus, and small for gestational age) was analyzed. The study showed that active smoking at inclusion was associated with an elevated concentration of interleukin-8. Furthermore, maternal obesity was associated with an elevated concentration of C-reactive protein and monocyte chemoattractant protein-1. Analysis of the data showed no statistically significant variations in the concentration of the assessed inflammatory markers for neither preeclampsia, gestational diabetes mellitus, nor small for gestational age. The current study promotes future research on the pathophysiology of twin pregnancies in relation to adverse pregnancy outcomes, as the literature within the area remains scarce.

Longitudinal evaluation of fetal and infant AGD in healthy children: association with penile size, testosterone and DHT.

CONTEXT: The anogenital distance (AGD) is considered a postnatal readout of early fetal androgen action. Little is known of prenatal AGD and how it correlates with AGD postnatally. OBJECTIVES: We present longitudinal measurements of fetal- and infant AGD. We evaluate the impact of testosterone and dihydrotestosterone at minipuberty on AGD and penile size. DESIGN: Secondary analyses of an observational, prospective pregnancy and birth cohort, COPANA (2020-2022). SETTING: Copenhagen University Hospital - Rigshospitalet. PARTICIPANTS: 685 healthy, singleton pregnant women enrolled, 657 women attended 3rd trimester ultrasound, 589 infants completed follow-up. MAIN OUTCOME MEASURES: 3rd trimester ultrasound (GW29-34): Fetal AGD. Minipuberty clinical examination (app. 3.5 months postpartum): infant AGD, penile width and stretched length (SPL), circulating testosterone and dihydrotestosterone (LC-MS/MS). RESULTS: AGD was available in 650/657 fetuses (310 boys) and 588/589 infants (287 boys). Boys had longer fetal and infant AGD compared to girls; fetal AGDas: mean (SD) 21.4 mm (±3.5), fetal AGDaf: 12.8 mm (±2.3), p < 0.001, infant AGDas: 32.0 mm (±5.6) and infant AGDaf: 15.8 (±3.3), p < 0.001. Fetal AGD correlated with infant AGD in boys and girls (Spearman's r = 0.275, p < 0.001 and r = 0.189, p = 0.001 respectively), but not with circulating testosterone or dihydrotestosterone at minipuberty. Penile size correlated positively with circulating androgen levels at minipuberty, i.e.: SPL vs testosterone: r = 0.235, p < 0.001. CONCLUSIONS: AGD is sexual dimorphic already in the 3rd trimester. Fetal and infant AGD correlates. AGD is associated with body size but not circulating androgen levels at minipuberty. These findings suggest that fetal and infant AGD, reflect androgen action during early fetal development.

The Consequences of A History of Violence on Women's Pregnancy and Childbirth in the Nordic Countries: A Scoping Review.

Violence against women (VAW) is a global challenge also in the childbearing period. Despite high gender equality, there is a high prevalence of VAW in the Nordic countries. This scoping review aims to explore predictors for and consequences of a history of violence on women's pregnancy and childbirth in the Nordic countries, including women's experience of the impact of violence and the interventions used to detect, address consequences, and prevent further violence. The framework by Arksey and O'Malley was followed, and English, Finnish, Icelandic, Norwegian, Danish, and Swedish literature was included. The population was women aged ≥18 residing in the Nordic countries during the perinatal period. Eight databases were searched: MEDLINE, CINAHL, PubMed, PsycINFO, Web of Science, ASSIA, Social Services-, and Sociological abstracts. There was no limitation of the search time frame. The initial screening resulted in 1,104 records, and after removing duplicates, 452 remained. Finally, 61 papers met the inclusion criteria. The results covering the past 32 years indicated that childbearing women with a history of violence are at greater risk of common complaints and hospitalization during pregnancy, fear of childbirth, Cesarean section, breastfeeding difficulties, and physical and mental health problems. While extensive research was found on the associations between a history of and current violence and outcomes related to pregnancy, there was a lack of intervention studies and studies from Finland. Efforts must be made to scientifically test the methods used to reduce and treat the adverse effects of a history of violence and prevent further violence.

Cohort profile: The Copenhagen Analgesic Study-The COPANA cohort.

BACKGROUND: Development of the gonads during fetal life is complex and vital for adult reproductive health. Cell and animal studies have shown an alarming effect of mild analgesics on germ cells in both males and females. More than 50% of pregnant women use mild analgesics during pregnancy, which potentially could compromise the reproductive health of the next generation. OBJECTIVES: We present a research protocol designed to evaluate the effect of prenatal exposure to mild analgesics and endocrine-disrupting chemicals on gonadal function in the offspring. POPULATION: Healthy, singleton pregnant women and their partners. DESIGN: The COPANA cohort is a prospective, observational pregnancy and birth cohort. METHODS: Participants were enrolled during the first trimester of pregnancy. Information on the use of mild analgesics was collected retrospectively 3 months prior to pregnancy and prospectively every 2 weeks throughout the study. We collected extensive data on lifestyle and reproductive health. Biospecimens were collected in the first trimester (maternal and paternal urine- and blood samples), in the third trimester in conjunction with a study-specific ultrasound scan (maternal urine sample), and approximately 3 months post-partum during the infant minipuberty period (maternal and infant urine- and blood samples). A comprehensive evaluation of reproductive function in the infants during the minipuberty phase was performed, including an ultrasound scan of the testis or ovaries and uterus. PRELIMINARY RESULTS: In total, 685 pregnant women and their partners were included between March 2020 and January 2022. A total of 589 infants (287 males) and their parents completed the follow-up during the minipuberty phase (December 2020-November 2022). CONCLUSIONS: The Copenhagen Analgesic Study holds the potential to provide novel and comprehensive insights into the impact of early and late prenatal exposure to mild analgesics and other endocrine-disrupting chemicals on future reproductive function in the offspring.

Pregnant women's attitudes to and experiences with a smartphone-based self-test for prediction of pre-eclampsia: a qualitative descriptive study.

OBJECTIVES: To explore attitudes to and experiences using a smartphone-based self-test for prediction of pre-eclampsia among pregnant women. DESIGN: A qualitative, descriptive study. SETTING: An obstetrical care unit at a university hospital in Denmark. PARTICIPANTS: Twenty women who had participated in the Salurate trial, a clinical trial testing the efficacy of a smartphone-based self-test for prediction of pre-eclampsia, were purposefully chosen for the study, using maximum variation sampling. DATA COLLECTION AND ANALYSIS: Data were collected by semistructured, individual, face-to-face interviews conducted from 4 October 2018 to 8 November 2018. Data were transcribed verbatim and analysed by means of thematic analysis. RESULTS: Qualitative thematic analysis resulted in the identification of three main themes: Raising awareness, self-testing has the potential to be an integrated part of pregnancy and trusting in technology. Two subthemes were identified under each main theme. CONCLUSIONS: The smartphone-based self-test for prediction of pre-eclampsia has potential to be integrated into antenatal care, and women found it feasible to use. However, testing affected the participating women psychologically, leading to feelings of worry as well as safety. Therefore, if self-testing is implemented, it is important to take actions to handle adverse psychological side effects, including increasing knowledge on pre-eclampsia and having healthcare professionals ongoingly address the psychological state of women throughout pregnancy. In addition, it is essential to emphasise the importance of subjective bodily sensations during pregnancy, including fetal movements. Further studies on the experience of being labelled low risk versus high risk for pre-eclampsia are warranted since this was not investigated in this trial.

Maternal factors associated with labor dystocia in low-risk nulliparous women. A systematic review and meta-analysis.

OBJECTIVE: To identify maternal factors associated with labor dystocia in low-risk nulliparous women. METHODS: MEDLINE, Embase, ClinicalTrials.gov, Cochrane, and CINAHL were searched for intervention studies and observational studies published from January 2000 to January 2022. Low-risk was defined as nulliparous women with a singleton, cephalic birth in spontaneous labor at term. Labor dystocia was defined by national or international criteria or treatment. Countries were restricted to OECD members. Two authors independently screened 11,374 titles and abstracts, extracted data, and assessed risk of bias using the Newcastle-Ottawa Scale. Results were presented narratively and by meta-analysis when compatible. RESULTS: Seven cohort studies were included. Overall, the certainty of the evidence was moderate. Three studies found that higher maternal age was associated with an increased frequency of labor dystocia (relative risk 1.68; 95% CI 1.43-1.98). Further three studies found that higher maternal BMI was associated with increased frequency of labor dystocia (relative risk 1.20; 95% CI 1.01-1.43). Maternal short stature, fear of childbirth, and high caffeine intake were also associated with an increased frequency of labor dystocia, while maternal physical activity was associated with a decreased frequency. CONCLUSION: Maternal factors associated with an increased frequency of labor dystocia were mainly maternal age, physical characteristics, and fear of childbirth. Maternal physical activity was associated with a decreased frequency. Intervention studies targeting these maternal factors would need to be initiated before or early in pregnancy to test the causality of the identified factors and labor dystocia.

Paracetamol use prior to and in early pregnancy: Prevalence and patterns among women with and without chronic medical diseases.

AIMS: Paracetamol is commonly consumed by pregnant women, even though recent data have questioned its safety. Having chronic medical diseases (CMDs) may influence the prevalence of use during pregnancy. We aimed to assess the prevalence and patterns of use 3 months prior to pregnancy and in the first trimester among women with and without CMDs and the potential influence of CMDs on frequent use in the first trimester. METHODS: We used patient-reported data from the Copenhagen Pregnancy Cohort from 1 October 2013 to 23 May 2019 with information on CMDs and paracetamol use. Prevalence and patterns of use were assessed descriptively and by multivariable logistic regression models. RESULTS: We included 24 019 pregnancies. Use of paracetamol prior to and in early pregnancy was significantly higher among women with CMDs compared to women without (40.7% vs. 35.8% and 9.1% vs. 5.1%, respectively). Women with CMDs were 2.7 times more likely to have a frequent intake compared to women without [aOR 2.69 (95% CI 2.05-3.32)]. Migraine, rheumatoid arthritis and mental disease were associated with a higher use of paracetamol [aOR 4.39 (3.20-6.02), aOR 4.32 (2.41-7.72) and aOR 2.74 (1.67-4.49), respectively]. CONCLUSIONS: Women with CMDs had a higher paracetamol use before and during pregnancy than women without CMDs. Women with migraine, rheumatoid arthritis and mental disease showed the highest risk of frequent use. This study highlights the importance of discussing pain relief in pregnancy and evaluating the influence of maternal CMDs when assessing adverse effects of paracetamol use during pregnancy.

Evaluation of the Effect of Supervised Group Exercise on Self-Reported Sleep Quality in Pregnant Women with or at High Risk of Depression: A Secondary Analysis of a Randomized Controlled Trial.

Poor sleep quality is common during pregnancy. Our objective was to evaluate the effect of supervised group physical exercise on self-reported sleep quality in pregnant women with or at high risk of depression, and secondly, to describe the association between sleep quality and psychological well-being during pregnancy and postpartum. This was a secondary analysis of a randomized controlled trial (n = 282) (NCT02833519) at Rigshospitalet, Denmark. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI), psychological well-being by the five-item WHO Well-Being Index (WHO-5). The intention-to-treat analysis showed no difference in mean global PSQI score neither at 29−34 weeks, 6.56 (95% CI: 6.05−7.07) in the intervention group and 7.00 (95% CI: 6.47−7.53) in the control group, p = 0.2, nor at eight weeks postpartum. Women with WHO-5 ≤ 50 reported higher mean global PSQI scores at baseline, 7.82 (95% CI: 7.26−8.38), than women with WHO-5 score > 50, mean 5.42 (95% CI: 5.02−5.82), p < 0.0001. A significant difference was also present post-intervention and eight weeks postpartum. No significant effect of group exercise regarding self-reported sleep quality was seen at 29−34 weeks of gestation or postpartum. Low psychological well-being was associated with poor sleep quality during pregnancy and postpartum.

Multivitamin use and risk of preeclampsia: A systematic review and meta-analysis.

INTRODUCTION: Preeclampsia is associated with adverse maternal and neonatal outcomes. It is unclear whether multivitamin use reduces the risk of preeclampsia. This systematic review and meta-analysis aimed to evaluate the association between multivitamin use and the risk of preeclampsia. MATERIAL AND METHODS: We searched PubMed, Embase and the Cochrane Library from database inception to July 2021. Randomized controlled trials (RCTs), case-control and cohort studies assessing the association between multivitamin use and risk of preeclampsia were eligible. Studies of treatment with a single micronutrient were excluded. Relative risks and 95% confidence intervals (95% CI) were calculated using random-effects models. RoB2, the Newcastle Ottawa Scale and GRADE were used to assess risk of bias and quality of evidence. The protocol was registered in PROSPERO (no. CRD42021214153). RESULTS: Six studies were included (33 356 women). Only two RCTs were found, both showing a significantly decreased risk of preeclampsia in multivitamin users. These studies were not compatible for meta-analysis due to clinical heterogeneity. A meta-analysis of observational studies using a random-effects model showed an unchanged risk of preeclampsia following multivitamin use (relative risk 0.85, 95% CI 0.69-1.03). The quality of evidence according to GRADE was very low. CONCLUSIONS: Very weak evidence suggests that multivitamin use might reduce the risk of preeclampsia; however, more research is needed. Large RCTs should be prioritized. The results of this review do not allow any final conclusions to be drawn regarding a preventive effect of multivitamin use in relation to preeclampsia.

Psychological well-being and worries among pregnant women in the first trimester during the early phase of the COVID-19 pandemic in Denmark compared with a historical group: A hospital-based cross-sectional study.

INTRODUCTION: A pandemic may negatively influence psychological well-being in the individual. We aimed to assess the potential influence of the first national lockdown in Denmark (March to June 2020) due to the COVID-19 pandemic on psychological well-being and the content and degree of worries among pregnant women in early pregnancy. MATERIAL AND METHODS: In this hospital-based cross-sectional study based on self-reported data we compared psychological well-being and worries among women who were pregnant during the first phase of the pandemic (COVID-19 group) (n = 685), with women who were pregnant the year before (Historical group) (n = 787). Psychological well-being was measured by the five-item World Health Organization Well-being Index (WHO-5), using a score ≤50 as indicator of reduced psychological well-being. Differences in WHO-5 mean scores and in the prevalence of women with score ≤50 were assessed using general linear and log-binomial regression analyses. The Cambridge Worry Scale was used to measure the content and degree of major worries. To detect differences between groups, Pearson's Chi-square test was used. RESULTS: We found no differences in mean WHO-5 score between groups (mean difference) 0.1 (95% CI -1.5 to 1.6) or in the prevalence of women with WHO-5 score ≤50 (prevalence ratio 1.04, 95% CI 0.83-1.29) in adjusted analyses. A larger proportion of women in the COVID-19 group reported major worries about Relationship with husband/partner compared with the Historical group (3% [n = 19] vs 1% [n = 6], p = 0.04), and 9.2% in the COVID-19 group worried about the possible negative influence of the COVID-19 restrictions. CONCLUSIONS: Our findings indicate that national restrictions due to the COVID-19 pandemic did not influence the psychological well-being or the content and degree of major worries among pregnant women. However, a larger proportion of women in the COVID-19 group reported major worries concerning Relationship with husband/partner compared with the Historical group and 9.2% in the COVID-19 group worried about the possible negative influence of the COVID-19 restrictions.

Lifestyle Habits among Pregnant Women in Denmark during the First COVID-19 Lockdown Compared with a Historical Period-A Hospital-Based Cross-Sectional Study.

The first national lockdown in Denmark due to the COVID-19 pandemic was declared on 11 March 2020. From this date, national restrictions were imposed. We aimed to assess the potential influence of this first nationwide lockdown on exercise, alcohol consumption, and smoking in early pregnancy. Using a cross-sectional study based on routinely collected patient-reported data, we compared the lifestyle habits of women who were pregnant during the first phase of the pandemic (COVID-19 group) (n = 685) with those of women who were pregnant the year before (Historical group) (n = 787). We found a reduction in any exercise (PR = 0.91, 95% CI (0.84 to 0.99), in adherence to national recommendations of exercise (PR = 0.89, 95% CI (0.80 to 0.99), in cycling (15% vs. 28%, p < 0.0001), and swimming (0.3% vs. 3%, p = 0.0002) in the COVID-19 group compared with the Historical group. The prevalence of binge drinking was reduced in the COVID-19 group compared with the Historical group (PR = 0.80, 95% CI (0.68 to 0.93). In contrast, the prevalence of any weekly alcohol consumption and smoking cessation during pregnancy was similar between groups. Our findings indicate that national restrictions due to the COVID-19 pandemic influenced the lifestyle habits of pregnant women and should be addressed in antenatal counseling.

Cohort profile: The COPENHAGEN Minipuberty Study-A longitudinal prospective cohort of healthy full-term infants and their parents.

BACKGROUND: The hypothalamic-pituitary-gonadal (HPG) axis governs sexual maturation and reproductive function in humans. In early postnatal life, it is transiently active during which circulating sex steroids reach adult levels. While this so-called minipuberty represents a universal phenomenon in infants of both sexes, its role for early maturation and growth remains incompletely understood. OBJECTIVES: To provide normative data on auxology as well as serum and urinary hormone levels in healthy, full-term infants throughout the first year of life and to investigate associations of postnatal HPG axis dynamics as well as hormonal, genetic and environmental exposures with early genital development and growth. POPULATION: Healthy, Danish, full-term, singleton newborns including their parents. DESIGN: Single-centre, prospective, observational longitudinal pregnancy and birth cohort. METHODS: Newborns were followed with six repeated clinical examinations during a one-year follow-up period. An umbilical cord blood sample was drawn at birth. At each visit, infants underwent a clinical examination focusing on auxology and genital development. Further, blood (serum, plasma, DNA) and urine samples were collected at each visit. Mothers and fathers underwent a clinical examination and provided blood samples prior to and after birth. A subset of parents provided urine samples and breast milk samples. Pregnancy and obstetrical outcomes, and detailed parental questionnaires were compiled. PRELIMINARY RESULTS: Between August 2016 and August 2018, 2481 women with singleton pregnancies were invited to participate of which 298, including their partners, were enrolled (12.0%). A total of 268 healthy, full-term newborns born appropriate for gestational age (AGA) were included at birth, 233 newborns participated in the postnatal follow-up period and 186 completed the one-year follow-up period (9.4% and 7.5%, respectively). CONCLUSION: The COPENHAGEN Minipuberty Study provides detailed, longitudinal data on early genital development and growth including hormonal and genetic profiles and environmental exposure in healthy infants including additional data in their parents.

Worries among pregnant Danish women with chronic medical conditions - A cross sectional study with data from the Copenhagen pregnancy cohort.

OBJECTIVE: Pregnancy is a time of uncertainty and worries are common. Pregnant women with somatic chronic medical conditions (SCMC) are at higher risk of adverse pregnancy outcomes and perinatal mental illness than women without SCMC. We aimed to describe the degree and content of worries in early pregnancy among Danish women with SCMC compared with women without SCMC. STUDY DESIGN: We conducted a cross-sectional study with self-reported questionnaires answered by 28,794 women from 2012─2019 during 1st trimester at a large university hospital in Denmark. MAIN OUTCOME MEASURES: We used the Cambridge Worry Scale (CWS). The outcomes of interest were the prevalence of major worry at item level (n/%) and the total CWS score (mean/SEM) as expression of the degree and content of worries. Univariate and multivariable regression analysis were performed. RESULTS: Women with SCMC reported a significantly higher total CWS score (aMD 1.50, 95% CI: 1.20-1.80). Women with SCMC were significantly more likely to report major worry in relation to own health (aOR 2.72, 95% CI: 2.43-3.08), the baby's health (aOR 1.40 95% CI 1.31-1.52), the process of giving birth (aOR 1.12, 95% CI: 1.04-1.21), the possibility of preterm labor (aOR 1.44, 95% CI: 1.28-1.63), and miscarriage (aOR 1.34, 95% CI: 1.24-1.43). CONCLUSION: Women with SCMC reported higher overall degree of worry during early pregnancy and an increased risk of major worry in relation to own health, pregnancy complications and giving birth. In antenatal care, these worries should be addressed by clinicians.

Short-term oestrogen as a strategy to prevent postpartum depression in high-risk women: protocol for the double-blind, randomised, placebo-controlled MAMA clinical trial.

INTRODUCTION: Postpartum depression affects 10%-15% of women and has a recurrence rate of 40% in subsequent pregnancies. Women who develop postpartum depression are suspected to be more sensitive to the rapid and large fluctuations in sex steroid hormones, particularly estradiol, during pregnancy and postpartum. This trial aims to evaluate the preventive effect of 3 weeks transdermal estradiol treatment immediately postpartum on depressive episodes in women at high risk for developing postpartum depression. METHODS AND ANALYSIS: The Maternal Mental Health Trial is a double-blind, randomised and placebo-controlled clinical trial. The trial involves three departments of obstetrics organised under Copenhagen University Hospital in Denmark. Women who are singleton pregnant with a history of perinatal depression are eligible to participate. Participants will be randomised to receive either transdermal estradiol patches (200 µg/day) or placebo patches for 3 weeks immediately postpartum. The primary outcome is clinical depression, according to the Diagnostic and Statistical Manual of Mental Disorders-V criteria of Major Depressive Disorder with onset at any time between 0 and 6 months postpartum. Secondary outcomes include, but are not limited to, symptoms of depression postpartum, exclusive breastfeeding, cortisol dynamics, maternal distress sensitivity and cognitive function. The primary statistical analysis will be performed based on the intention-to-treat principle. With the inclusion of 220 participants and a 20% expected dropout rate, we anticipate 80% power to detect a 50% reduction in postpartum depressive episodes while controlling the type 1 error at 5%. ETHICS AND DISSEMINATION: The study protocol is approved by the Regional Committees on Health Research Ethics in the Capital Region of Denmark, the Danish Medicines Agency and the Centre for Data Protection Compliance in the Capital Region of Denmark. We will present results at scientific meetings and in peer-reviewed journals and in other formats to engage policymakers and the public. TRIAL REGISTRATION NUMBER: NCT04685148.

Degree of pregnancy planning and recommended pregnancy planning behavior among women with and without chronic medical conditions - A large hospital-based cross-sectional study.

INTRODUCTION: Pregnancy planning allows women to engage in pregnancy planning behaviors to optimize health status in the preconception period. Women with chronic medical conditions have a higher risk for adverse pregnancy outcomes and therefore preconception care is recommended. The aim was to compare pregnancy planning among women with and without chronic medical conditions, and to assess adherence to the recommended pregnancy planning behaviors on folic acid intake, physical activity and abstention from smoking and alcohol, among women with and without chronic medical conditions stratified by pregnancy planning. MATERIAL AND METHODS: A cross-sectional study with data from 28 794 pregnancies. Pregnancy planning was measured with the Swedish Pregnancy Planning Scale. Multiple Poisson regression with robust variance estimates was used to assess the associations between chronic medical condition (yes/no and main categories) and pregnancy planning, and chronic medical condition status and pregnancy planning behaviors stratified by pregnancy planning. RESULTS: In the study population, 74% reported high degree of pregnancy planning, and 22% had one or more chronic medical conditions. We found no overall association between chronic medical condition and pregnancy planning (adjusted rate ratio [RR] 1.00, 95% confidence interval [CI] 0.98-1.01). However, women with type 2 diabetes and mental illness were significantly less likely to plan their pregnancies than women without these conditions (aRR 0.73, 95% CI 0.61-0.88; aRR 0.91, 95% CI 0.87-0.96, respectively). Women with chronic medical conditions were more likely to adhere to the recommended planning behaviors; intake of folic acid, abstention from alcohol prior to pregnancy and no binge drinking in early pregnancy. CONCLUSIONS: Overall, pregnancies were highly planned. Women with chronic medical conditions did not show a higher degree of pregnancy planning than women without chronic medical conditions but were, however. more likely to adhere to the generally recommended pregnancy planning behaviors (ie intake of folic acid and abstention from alcohol intake). Only women with mental illness and type 2 diabetes reported a lower degree of pregnancy planning. It is important that we continuously address pregnancy planning and planning behaviors for both women with and women without chronic medical conditions, especially women with type 2 diabetes and mental illness.

[Magnesium sulphate treatment decreases the risk of cerebral palsy after preterm birth].

Children born preterm have an increased risk of severe morbidity, e.g. cerebral palsy (CP), compared to children born at term. CP cannot be treated, which is why a prophylactic approach is essential, as argued in this review. Six randomised controlled trials (RCTs) have provided data on MgSO4 treatment as CP neuroprotection in preterm birth, including a new RCT from Denmark. Recently, an updated meta-analysis with trial sequential analysis detected a significant neuroprotective effect of MgSO4 treatment in preterm birth. There is now sufficient evidence, that MgSO4 treatment should be used as neuroprotection in preterm birth.

Multivitamin intake does not affect the risk of preterm and very preterm birth.

INTRODUCTION: The aim of this study was to assess the association between multivitamin intake during pregnancy and the risk of preterm birth and very preterm birth. METHODS: The study population comprised 15,629 women from the Copenhagen Pregnancy Cohort with data on pregnancy multivitamin intake during their first trimester who gave birth to singletons from October 2012 to October 2016. Data on pregnancy multivitamin intake were linked to the Medical Birth Registry to identify the birth outcome. The main outcome measures were preterm birth before 37 weeks of gestation and very preterm birth before 32 weeks of gestation. RESULTS: Among the included women, 85.6% had taken daily pregnancy multivitamins during their first trimester. We found no evidence that pregnancy multivitamin intake during the first trimester was associated with a decreased risk of preterm birth (adjusted odds ratio (OR) = 1.01; 95% confidence interval (CI): 0.77-1.33) or very preterm birth (adjusted OR = 1.06; 95% CI: 0.63-1.77). Stratification for BMI into lesser-than 25 kg/m2 and ≥ 25 kg/m2 did not alter these findings. CONCLUSIONS: Pregnancy multivitamin intake during the first trimester was not associated with a decreased risk of preterm birth or very preterm birth among women in a high-income population. FUNDING: none. TRIAL REGISTRATION: not relevant.

Experiences of participation in supervised group exercise among pregnant women with depression or low psychological well-being: A qualitative descriptive study.

OBJECTIVE: To explore experiences with supervised group exercise during pregnancy in women with depression or low psychological well-being. DESIGN: A qualitative descriptive study based on semi-structured, individual, in-depth interviews analyzed by means of thematic analysis. SETTING: The Department of Obstetrics, Rigshospitalet, Copenhagen University Hospital, Denmark. PARTICIPANTS: Through a purposeful, criterion-based sampling strategy, women with a current diagnosis of depression with prescribed antidepressant and/or a score ≤50 on the five-item World Health Organization Well-being Index were included. The women were recruited from a randomized controlled trial on the effects of supervised group exercise (the EWE study) and participated in the exercise program during the period 26 January 2017-8 March 2018. A total of 282 pregnant women participated in the RCT, of which 143 women were allocated to the intervention group. Of these, 27 women were eligible and were invited; 19 accepted the invitation and were included in the current qualitative descriptive study. Diversity of age, parity, level of education and employment status was seen in the sample. The average time from completing the exercise program to conducting the interview was 6.5 months, ranging from 1 week to 13 months. INTERVENTION: The participants were offered an in-hospital supervised group exercise program twice weekly for 12 weeks from 17-22 weeks gestation in addition to standard antenatal care. MEASUREMENTS AND FINDINGS: Qualitative thematic analysis of the interviews resulted in the identification of the overarching theme: Vulnerable yet strong. This theme was comprised from three main themes (1) From judging the body to feeling it, (2) A "we" is created, and (3) Taking responsibility and succeeding, together with nine sub-themes. KEY CONCLUSIONS: The supervised group exercise intervention provided experiences of peer support and increased body awareness, which contributed to an experience of improved psychological equilibrium and preparedness for the coming birth and motherhood. The findings suggest that participation in group-based supervised exercise during pregnancy in women with depression or low psychological well-being contributes to psychological resilience, which may persist as a positive influence postpartum and beyond. IMPLICATIONS FOR PRACTICE: In-hospital supervised group-based exercise can be a safe means to health promotion in a secure environment that supports pregnant women's physical and mental well-being while also preparing them for birth and the transition to motherhood.
