- Background Neonatal seizures have been associated with increased mortality and impaired neurodevelopment and, knowledge about risk factors may be useful for prevention. Clear associations have been established between labor-related risk factors and seizures in asphyxiated neonates. However, there is limited information about why some vigorous term-born infants experience seizures. Objectives Our aim was to assess antepartum and intrapartum risk factors for seizures in vigorous term-born neonates. Methods This was a national cohort study of singleton infants born at term in Sweden from 2009-2015. Vigorous was defined as an Apgar score of at least 7 at 5 and 10 minutes. Data on the mothers and infants were obtained from the Swedish Medical Birth Register and the Swedish Neonatal Quality Register. A diagnosis of neonatal seizures was the main outcome measure and the exposures were pregnancy and labor variables. Logistic regression analysis was used and the results are expressed as adjusted odds ratios (aOR) with 95% confidence intervals (CI). Results The incidence of neonatal seizures was 0.81/1,000 for 656 088 births. Seizures were strongly associated with obstetric emergencies (aOR 4.0, 95% CI 2.2-7.4), intrapartum fever and/or chorioamnionitis (aOR 3.4, 95% CI 2.1-5.3), and intrapartum fetal distress (aOR 3.0, 95% CI 2.4-3.7). Other associated intrapartum factors were: labor dystocia, occiput posterior position, operative vaginal delivery, and Cesarean delivery. Some maternal factors more than doubled the risk: a body mass of more than 40 (aOR 2.6, 95% CI 1.4-4.8), hypertensive disorders (aOR 2.3, 95% CI 1.7-3.1) and diabetes mellitus (aOR 2.6, 95% CI 1.7-4.1). Conclusion A number of intrapartum factors were associated with an increased risk of seizures in vigorous term-born neonates. Obstetric emergencies, intrapartum fever and/or chorioamnionitis and fetal distress were the strongest associated risks. The presence of such factors, despite a reassuring Apgar score could prompt close surveillance.

- Objective To develop a Core Outcome Set (COS) for treatment of perinatal depression.Design Systematic overview of outcomes reported in the literature and consensus development study.SettingInternational.Population Two hundred and twenty-two participants, mainly patients, healthcare professionals and researchers, representing 13 countries.Methods A systematic overview of outcomes reported in recently published research, a two-round Delphi survey and a consensus meeting at which the final COS was decided using modified nominal group technique.Main results In the literature search, 1772 abstracts were identified and evaluated, and 165 studies were finally included in the review. In all, 106 outcomes were identified and included in the Delphi survey. In all, 222 participants registered for the first round of the Delphi survey and 151 (68%) responded. In the second round, 123 (55%) participants responded. Thirteen participants attended the consensus meeting, where the following nine outcomes were agreed upon for inclusion in the final COS: self-assessed symptoms of depression, diagnosis of depression by a clinician, parent to infant bonding, self-assessed symptoms of anxiety, quality of life, satisfaction with intervention, suicidal thoughts, attempted or committed suicide, thoughts of harming the baby, and adverse events.Conclusions The relevant stakeholders prioritised outcomes and reached consensus on a COS comprising nine outcomes. We expect that this COS will contribute to the consistency and uniformity of outcome selection and reporting in future clinical trials involving treatment of perinatal depression.

- The risk for brain injury manifested as cerebral palsy is higher in very preterm born children than in term. Prenatal administration of magnesium sulfate (MgSO4 ) has been shown to be neuroprotective and reduces the proportion of very preterm born children later diagnosed with cerebral palsy. A Swedish national clinical practice guideline was implemented in March 2020, stipulating the administration of a single intravenous dose of 6g MgSO4 1-24h prior to delivery before gestational age 32+0, aiming for 90% treatment coverage. The aim of this study was to evaluate the feasibility of this new clinical practice guideline in the first year of its implementation.Data on MgSO4 treatment were collected by reviewing the medical charts of women who gave birth to live born children in gestational age 22+0-31+6 during the period of March 1, 2020 to February 28, 2021, at five Swedish university hospitals. Women with pre-eclampsia, eclampsia, or high elevated liver enzymes low platelets (HELLP) were excluded.A total of 388 women were eligible and 79% received treatment with MgSO4 . Of the 21% not receiving treatment, 9% did not receive treatment due to lack of knowledge about the clinical practice guideline, 9% were not possible to treat and 3% had missing data. The proportion treated increased from 72% to 87% from the first to the last 3months. Of those treated, 81% received the drug within the stipulated timeframe (mean 8.7h, median 3.4h).There was a positive trend over time in the proportion of women receiving MgSO4 treatment, but the a priori target of 90% was not reached during the first year of implementation. Our findings indicate that this target could be reached with additional information to clinicians.

- OBJECTIVE: To identify antepartum and intrapartum risk factors for neonatal seizures in the absence of hypoxic ischemic encephalopathy (HIE).METHODS: Population-based case-control study. Of 98 484 births, 40 newborns at 34 gestational weeks or later had seizures within the first 7 days of life. Cases (n = 40) and controls (n = 160) were retrieved from the University hospitals of Örebro for 1994-2013 and Uppsala for 2003-2013. Demographics and characteristics of pregnancy, labor, delivery, and neonatal data were analyzed. Crude odds ratio (OR) and adjusted odds ratios (AOR) with 95% confidence intervals (CIs) for antenatal and intrapartum factors were calculated using logistic regression analysis. Main outcome measure was neonatal seizures within the first 7 days of life.RESULTS: The incidence of neonatal seizures without HIE was 0.41/1000 live births. Antenatal risk factors for neonatal seizures were as follows: short maternal stature (AOR: 5.4; 1.8-16.5); previous caesarean section (AOR: 4.8; 1.5-15.0); and assisted fertilization (AOR: 6.8; 1.3-35.2). Intrapartum risk factors were as follows: induction of labor (AOR: 5.7; 1.8-17.7); preterm birth (AOR: 13.5; 3.7-48.9); and head circumference >37 cm (AOR: 6.9; 1.4-34.8).CONCLUSIONS: Preterm birth was the strongest risk factor for neonatal seizures in the absence of HIE. The results also indicate that feto-pelvic disproportion is associated with the occurrence of seizures.RATIONALE: Antepartum and intrapartum risk factors for newborn seizures in the absence of HIE were investigated in a case-control study. Out of 98 484 births at 34 gestational weeks or more, 40 newborns had seizures without HIE. All had a normal Apgar score although they later presented with seizures. Preterm birth was the strongest risk factor (OR: 13.5; 95% CI: 3.7-48.9). Our results also indicate that feto-pelvic disproportion is of importance. Furthermore, a history of prior caesarean was associated with seizures. This is the first study to assess obstetric risk factors for newborn seizures separate from those with seizures and concomitant HIE. The distinction is of importance due to different etiologies, treatments, and preventive strategies.

- BACKGROUND: Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders.METHODS: We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC). The GWAS of SA was conditioned on psychiatric disorders using GWAS summary statistics via multitrait-based conditional and joint analysis, to remove genetic effects on SA mediated by psychiatric disorders. We investigated the shared and divergent genetic architectures of SA, psychiatric disorders, and other known risk factors.RESULTS: Two loci reached genome-wide significance for SA: the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with SA after conditioning on psychiatric disorders and replicated in an independent cohort from the Million Veteran Program. This locus has been implicated in risk-taking behavior, smoking, and insomnia. SA showed strong genetic correlation with psychiatric disorders, particularly major depression, and also with smoking, pain, risk-taking behavior, sleep disturbances, lower educational attainment, reproductive traits, lower socioeconomic status, and poorer general health. After conditioning on psychiatric disorders, the genetic correlations between SA and psychiatric disorders decreased, whereas those with nonpsychiatric traits remained largely unchanged.CONCLUSIONS: Our results identify a risk locus that contributes more strongly to SA than other phenotypes and suggest a shared underlying biology between SA and known risk factors that is not mediated by psychiatric disorders.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aims of the study were to investigate foreign-born women’s lifestyle and health before and during early pregnancy and compare them with those of Nordic-born women.Methods: Women recruited at antenatal clinics in Sweden answered a questionnaire in Swedish, English or Arabic or by telephone interview with an interpreter. Questions covered pregnancy planning and periconceptional lifestyle and health. The responses of women born in or outside Europe were compared with those of Nordic-born women. The impact of religiousness and integration on periconceptional lifestyle and health was also investigated.Results: Twelve percent of participants (N = 3389) were foreign-born (n = 414). Compared with Nordic women, European and non-European women consumed less alcohol before conception (respectively, adjusted odds ratio [aOR] 0.38; 95% confidence interval [CI] 0.24, 0.58 and aOR 0.14; 95% CI 0.10, 0.19) and during early pregnancy (respectively, aOR 0.61; 95% CI 0.40, 0.91 and aOR 0.20; 95% CI 0.14, 0.29). Non-European women used less tobacco and were less physically active, but body mass index (BMI) did not differ between groups. Self-perceived health, stress and anxiety during early pregnancy did not differ, but non-European women more often had depressive symptoms (aOR 1.67; 95% CI 1.12, 2.51). Non-European women’s healthy lifestyle was associated with religiousness but not with the level of integration.Conclusions: Non-European women were overall less likely to engage in harmful lifestyle habits before and during early pregnancy but were more likely to suffer from depressive symptoms in comparison with Nordic women.

- BackgroundSystematic reviews often conclude low confidence in the results due to heterogeneity in the reported outcomes. A Core Outcome Set (COS) is an agreed standardised collection of outcomes for a specific area of health. The outcomes included in a COS are to be measured and summarized in clinical trials as well as systematic reviews to counteract this heterogeneity.AimThe aim is to identify, compile and assess final and ongoing studies that are prioritizing outcomes in the area of pregnancy and childbirth.MethodsAll studies which prioritized outcomes related to pregnancy and childbirth using consensus method, including Delphi surveys or consensus meetings were included. Searches were conducted in Ovid MEDLINE, EMBASE, PsycINFO, Academic Search Elite, CINAHL, SocINDEX and COMET databases up to June 2021. For all studies fulfilling the inclusion criteria, information regarding outcomes as well as population, method, and setting was extracted. In addition, reporting in the finalized studies was assessed using a modified version of the Core Outcome Set-STAndards for Reporting.ResultsIn total, 27 finalized studies and 42 ongoing studies were assessed as relevant and were included. In the finalized studies, the number of outcomes included in the COS ranged from 6 to 51 with a median of 13 outcomes. The majority of the identified COS, both finalized as well as ongoing, were relating to physical complications during pregnancy.ConclusionThere is a growing number of Core Outcome Set studies related to pregnancy and childbirth. Although several of the finalized studies follow the proposed reporting, there are still some items that are not always clearly reported. Additionally, several of the identified COS contained a large number (n > 20) outcomes, something that possibly could hinder implementation. Therefore, there is a need to consider the number of outcomes which may be included in a COS to render it optimal for future research.

- ObjectiveTo determine survival and outcomes in infants born at 22-24 weeks of gestation in a centre with a uniformly active approach to management of extremely preterm infants.Study designSingle-centre retrospective cohort study including infants born 2006-2015. Short-term morbidities assessed included retinopathy of prematurity, necrotising enterocolitis, patent ductus arteriosus, intraventricular haemorrhage, periventricular malacia and bronchopulmonary dysplasia. Neurodevelopmental outcomes assessed included cerebral palsy, visual impairment, hearing impairment and developmental delay.ResultsTotal survival was 64% (143/222), ranging from 52% at 22 weeks to 70% at 24 weeks. Of 133 (93%) children available for follow-up at 2.5 years corrected age, 34% had neurodevelopmental impairment with 11% classified as moderately to severely impaired. Treatment-requiring retinopathy of prematurity, severe bronchopulmonary dysplasia, visual impairment and developmental delay correlated with lower gestational age.ConclusionsA uniformly active approach to all extremely preterm infants results in survival rates that are not distinctly different across the gestational ages of 22-24 weeks and more than 50% survival even in infants at 22 weeks. The majority were unimpaired at 2.5 years, suggesting that such an approach does not result in higher rates of long-term adverse neurological outcome.

- ObjectiveTo investigate whether mild neonatal hypoxic ischaemic encephalopathy (HIE) in term born infants is associated with cerebral palsy, epilepsy, mental retardation and death up to 6 years of age.DesignPopulation-based cohort study.SettingSweden, 2009–2015.PopulationLive term born infants without congenital malformations or chromosomal abnormalities (n = 505 075).MethodsBirth and health data were retrieved from Swedish national health and quality registers. Mild HIE was identified by diagnosis in either the Swedish Medical Birth Register or the Swedish Neonatal Quality Register. Cox proportional hazards regression was used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs).Main outcome measuresA composite of the outcomes cerebral palsy, epilepsy, mental retardation and death up to 6 years of age.ResultsMedian follow-up time was 3.3 years after birth. Of 414 infants diagnosed with mild HIE, 17 were classified according to the composite outcome and incidence rates were 12.6 and 2.9 per 1000 child-years in infants with and without HIE respectively. Infants with mild HIE was four times as likely to be diagnosed with the composite outcome (HR 4.42, 95% CI 2.75–7.12) compared with infants without HIE. When analysed separately, associations were found with cerebral palsy (HR 21.50, 95% CI 9.59–48.19) and death (HR 19.10, 95% CI 7.90–46.21). HRs remained essentially unchanged after adjustment for covariates.ConclusionsMild neonatal HIE was associated with neurological morbidity and mortality in childhood. Challenges include identifying infants who may develop morbidity and how to prevent adverse outcomes.

- Introduction Induction of labor is increasing. A common indication for induction of labor is late term and postterm pregnancy at 41 weeks or more. We aimed to evaluate if there are any differences regarding efficacy, safety, and women's childbirth experience between oral misoprostol and transvaginal balloon catheter for cervical ripening in women with a low-risk singleton pregnancy and induction of labor at 41(+0) to 42(+0 to 1) weeks of gestation. Material and methods In this observational study, based on data from the Swedish Postterm Induction Study (SWEPIS), a multicenter randomized controlled trial, a total of 1213 women with a low-risk singleton pregnancy at 41 to 42 weeks of gestation were induced with oral misoprostol (n = 744) or transvaginal balloon catheter (n = 469) at 15 Swedish delivery hospitals. The primary efficacy outcome was vaginal delivery within 24 h and primary safety outcomes were neonatal and maternal composite adverse outcomes. Secondary outcomes included time to vaginal delivery and mode of delivery. Women's childbirth experience was assessed with the Childbirth Experience Questionnaire (CEQ 2.0) and visual analog scale. We present crude and adjusted mean differences and relative risks (RR) with 95% CI. Adjustment was performed for a propensity score based on delivery hospital and baseline characteristics including Bishop score. Results Vaginal delivery within 24 h was significantly lower in the misoprostol group compared with the balloon catheter group (46.5% [346/744] versus 62.7% [294/469]; adjusted RR 0.76 95% CI 0.640.89]). Primary neonatal and maternal safety outcomes did not differ between groups (neonatal composite 3.5% [36/744] vs 3.2% [15/469]; adjusted RR 0.77 [95% CI 0.31-1.89]; maternal composite 2.3% [17/744] versus 1.9% [9/469]; adjusted RR 1.70 [95% CI 0.58-4.97]). Adjusted mean time to vaginal delivery was increased by 3.8 h (95% CI 1.3-6.2 h) in the misoprostol group. Non-operative vaginal delivery and cesarean delivery rates did not differ. Women's childbirth experience was positive overall and similar in both groups. Conclusion Induction of labor with oral misoprostol compared with a transvaginal balloon catheter was associated with a lower probability of vaginal delivery within 24 h and a longer time to vaginal delivery. However, primary safety outcomes, non-operative vaginal delivery, and women's childbirth experience were similar in both groups. Therefore, both methods can be recommended in women with low-risk postdate pregnancies.
