- Introduction We aimed to assess cognitive function in women with preeclampsia stratified by severity, before and after onset of disease. Material and methods Prospective study performed at a referral hospital in Cape Town, South Africa. Pregnant women between 20 and 42 weeks of gestation with eclampsia, pulmonary edema and preeclampsia without severe features, and a normotensive pregnancy were approached. Women were included at diagnosis of preeclampsia or at admission for delivery (women with normotensive pregnancies). Two cognitive assessments, the Cognitive Failure Questionnaire to assess the cognitive function subjectively before inclusion in the study, and Montreal Cognitive Assessment to assess the current cognitive function objectively before discharge from the hospital after delivery, were performed. Results We included 61 women with eclampsia, 28 with preeclampsia complicated by pulmonary edema, 38 with preeclampsia without severe features, and 26 with normotensive pregnancies. There was no difference in cognitive function from early pregnancy between groups. Women with eclampsia and preeclampsia complicated by pulmonary edema scored lower on the Montreal Cognitive Assessment at time of discharge compared with women with normotensive pregnancies. The results were attenuated in pulmonary edema after adjustment for confounders. Conclusions Women with preeclampsia complicated by pulmonary edema and in particular eclampsia had impaired cognitive function after onset of disease compared with women with normotensive pregnancies. The impairment did not seem to be present before onset of disease. Women with preeclampsia without severe features did not have impaired cognitive function.

Journal article (peer-reviewed)abstract
- Background: Information about and invitation to participate in a clinical trial involving an intervention during childbirth may cause fear or worry in pregnant women. The aim of this study was to describe nulliparous women's experiences of receiving an invitation to participate in a randomized controlled trial (RCT) of lateral episiotomy versus no episiotomy in vacuum-assisted delivery (EVA trial). Methods: This qualitative study was nested in the ongoing EVA trial. Data were collected through semistructured telephone interviews with 23 women regarding their experiences of the information and invitation to participate in the EVA trial. Interviews were audio-recorded and transcribed verbatim. A qualitative content analysis was used to analyse the interview contents. Results: Three main experience categories were identified among the participants. "Timing of trial information and understanding" revealed that women preferred to obtain information about the trial early on during pregnancy. "Reasons to consent to or decline participation in the trial" encompassed a variety of reasons for women to consent, such as goodwill for science or personal benefits, or to decline, such as not wanting to be randomized or fear of increased risk of having a vacuum-assisted delivery. "Thoughts evoked regarding childbirth" were diverse, ranging from not being affected at all to having increased anxiety. Conclusions: The women's experience of receiving an invitation to participate in an RCT of episiotomy in vacuum-assisted delivery varied widely, from immediately giving consent without further worries to increased anxiety or declining participation. Early and personal information with time for reflection was considered most satisfactory.

Aspirin use during pregnancy and the risk of bleeding complications : a Swedish population-based cohort study
- 2021
-
In: American Journal of Obstetrics and Gynecology. - : Elsevier. - 0002-9378 .- 1097-6868. ; 224:1, s. 95.e1-95.e12

Journal article (peer-reviewed)abstract
- BACKGROUND: Aspirin is offered to pregnant women to prevent preeclampsia, a severe obstetrical complication. Large studies of nonpregnant populations have consistently shown that aspirin prophylaxis increases the risk of hemorrhagic complications. However, there have not been any population-based studies investigating this in a pregnant population.OBJECTIVE: This study aimed to investigate whether aspirin use during pregnancy is associated with an increased risk of bleeding complications.STUDY DESIGN: We performed a register-based cohort study using the Swedish Pregnancy Register wherein we examined 313,624 women giving birth between January 2013 and July 2017. Logistic regression was used to assess the risk of antepartum, intrapartum, and postpartum hemorrhage. A propensity score and inverse probability treatment weighting was used to generate an odds ratio that corrects for differences in baseline characteristics.RESULTS: Aspirin use was registered in 4088 (1.3%) women during pregnancy. Compared with women who did not take aspirin, aspirin use was not associated with bleeding complications during the antepartum period (adjusted odds ratio, 1.22; 95% confidence interval, 0.97-1.54). However, aspirin users had a higher incidence of intrapartum bleeding (2.9% aspirin users vs 1.5% nonusers; adjusted odds ratio, 1.63; 95% confidence interval, 1.30-2.05), postpartum hemorrhage (10.2% vs 7.8%; adjusted odds ratio, 1.23; 95% confidence interval, 1.08-1.39), and postpartum hematoma (0.4% vs 0.1%; adjusted odds ratio, 2.21; 95% confidence interval, 1.13-4.34). The risk of a neonatal intracranial hemorrhage was also increased (0.07% vs 0.01%; adjusted odds ratio, 9.66; 95% confidence interval, 1.88-49.48). After stratifying by mode of birth, a higher incidence of bleeding among aspirin users was present for those who had a vaginal birth but not those who had a cesarean delivery.CONCLUSION: Using aspirin during pregnancy is associated with increased postpartum bleeding and postpartum hematoma. It may also be associated with neonatal intracranial hemorrhage. When offering aspirin during pregnancy, these risks need to be weighed against the potential benefits.

Internet-based treatment for vulvodynia (EMBLA)-Study protocol for a randomised controlled study
- 2021
-
In: Internet Interventions. - : Elsevier. - 2214-7829. ; 25
-
Journal article (peer-reviewed)abstract
- Background: Vulvodynia is defined as vulvar pain for at least 3 months without a clear cause. To the best of our knowledge, there are no trials investigating the effects of internet treatment using CBT (Cognitive behavioural therapy) treatment with Acceptance and Commitment Therapy (ACT) components for women with vulvodynia. The aim of this study is to examine the effects of such a guided internet-based intervention on provoked vulvar pain during the waiting period before clinical treatment. Methods: We will randomise 52 patients to either guided internet-based intervention with CBT with (ACT) components or no intervention during the waiting period for treatment as usual. Online assessments are conducted at baseline, posttreatment, and at follow-up after 9 months. The primary outcome measure is provoked vulvar pain. Secondary outcomes are depression, anxiety, sexual function, and quality of life. Linear-mixed effect models will be used to assess the effect of the internet-based intervention on vulvar pain, pain acceptance, depression, anxiety, sexual function, and quality of life over time, by applying the intention-to-treat approach. Continuous data will be analysed with general linear models using intention-to-treat and also per protocol approaches to assess the effects of the intervention at different time points. Ordinal and binary data will be analysed with Mann Whitney's test, Fischer's exact test and multivariate logistic regression, respectively. Discussion: As a randomised controlled trial with short- and long-term follow-up points, the EMBLA study intends to provide a novel and better understanding regarding the treatment of vulvodynia and the role of internet-based treatment as a complement to standard care for women suffering from vulvodynia. The effects of vulvodynia on pain, sexual function, quality of life, depression, and anxiety are investigated. The study's results are expected to be of value in the planning of clinical care in the medical area. High dropout rates and technical difficulties associated with using the platform are common in similar studies. Trial registration number: NCT02809612

Duration of labor among women with thromboembolic events: A Swedish register study
- 2021
-
In: European Journal of Obstetrics and Gynecology and Reproductive Biology: X. - : Elsevier BV. - 2590-1613. ; 11
-
Journal article (peer-reviewed)abstract
- Introduction: Inflammation is central to initiation of labor and coagulation is closely interlinked with inflammation. Low-molecular-weight-heparin (LMWH) promotes inflammatory cervical remodeling, myometrium contractility and has been associated with shorter duration of labor. Material and methods: This was a cohort study of 136,661 deliveries 2013–2017, identified in the Swedish Pregnancy Register with prospectively collected pregnancy and labor characteristics. Information of duration of labor was retrieved from the electronic birth records and analyzed with Cox proportional hazard regressions according to previous or current thromboembolic disease (overall) with or without LMWH treatment with non-exposed as reference. Results: The crude hazard ratio for vaginal delivery was not different between women with thromboembolic disease and women without thromboembolic disease (HR 0.99, 95 % CI 0.91–1.09). A lower hazard ratio for vaginal delivery was observed among women with venous thromboembolism (VTE) with concomitant LMWH use/treatment (adjusted HR 0.86, 95 % CI 0.76−0.98) compared to non-exposed, implying a longer duration of labor in these cases. Conclusion: Thromboembolic disease was not associated with shorter duration of labor and in presence of LMWH these women experienced longer duration of labor. © 2021 The Authors

- IntroductionUterine rupture is an obstetric emergency associated with maternal and neonatal morbidity. The main risk factor is a prior cesarean section, with rupture occurring in subsequent labor. The aim of this study was to assess the risk of uterine rupture by labor duration and labor management.Material and methodsThis is a Swedish register-based cohort study of women who underwent labor in 2013–2018 after a primary cesarean section (n = 20 046). Duration of labor was the main exposure, calculated from onset of regular labor contractions and birth; both timepoints were retrieved from electronic medical records for 12 583 labors, 63% of the study population. Uterine rupture was calculated as events per 1000 births at different timepoints during labor. Risk estimates for uterine rupture by labor duration, induction of labor, use of oxytocin and epidural analgesia were calculated using Poisson regression, adjusted for maternal and birth characteristics. Estimates were presented as adjusted rate ratios (ARR) with 95% confidence intervals (CI).ResultsThe prevalence of uterine rupture was 1.4% (282/20 046 deliveries). Labor duration was 9.88 hours (95% CI 8.93–10.83) for women with uterine rupture, 8.20 hours (95% CI 8.10–8.31) for women with vaginal delivery, and 10.71 hours (95% CI 10.46–10.97) for women with cesarean section without uterine rupture. Few women (1.0/1000) experienced uterine rupture during the first 3 hours of labor. Uterine rupture occurred in 15.6/1000 births with labor duration over 12 hours. The highest risk for uterine rupture per hour compared with vaginal delivery was observed at 6 hours (ARR 1.20, 95% CI 1.11–1.30). Induction of labor was associated with uterine rupture (ARR 1.54, 95% CI 1.19–1.99), with a particular high risk seen in those induced with prostaglandins and no risk observed with cervical catheter (ARR 1.19, 95% CI 0.83–1.71). Labor augmentation with oxytocin (ARR 1.60, 95% CI 1.25–2.05) and epidural analgesia (ARR 1.63, 95% CI 1.27–2.10) were also associated with uterine rupture.ConclusionsLabor duration is an independent factor for uterine rupture among women attempting vaginal delivery after cesarean section. Medical induction and augmentation of labor increase the risk, regardless of maternal and birth characteristics.

Episiotomy or not? : Midwives' experiences of recruiting to a randomized controlled trial during pregnancy and labor – A qualitative study
- 2021
-
In: Sexual & Reproductive HealthCare. - : Elsevier. - 1877-5756 .- 1877-5764. ; 30
-
Journal article (peer-reviewed)abstract
- Objective: The performance of randomized controlled trials (RCTs) is dependent on recruitment. Recruiting women to RCTs regarding interventions during childbirth may be difficult due to time constraints and their vulnerable situation. Midwives play a major role in such recruitment. Few studies have investigated the views and experiences of recruiters. The aim of this study was to describe midwives' experiences of recruiting pregnant women regarding an RCT of lateral episiotomy or no episiotomy in vacuum-assisted delivery.Methods: In this qualitative study, 19 midwives were interviewed regarding their experiences. The midwives worked at antenatal health care centers or labor wards. The transcribed interviews were analyzed using content analysis.Results: Four categories appeared during the analysis, including "experiences and perceptions of providing trial information" and "the right timing in providing trial information," which varied among the midwives. Midwives' perceptions of how the women provided consent or declined participation, and the women's views and questions about the randomization and intervention, were summarized as "experiences of how the trial information was received by the women." In the final category, "perceived trial apprehensions and concerns," some midwives described ethical concerns related to the intervention and financial compensation to the staff involved.Conclusions: Midwives as recruiters would benefit from education and training in incorporating basic and advanced details of trial design and research methods, as well as training and support in recruitment. Awareness and management of the variation among potential recruiters is important when designing and performing an RCT.

Self‐rated health before pregnancy and adverse birth outcomes in Sweden : A population‐based register study
- 2021
-
In: Birth. - : John Wiley & Sons. - 0730-7659 .- 1523-536X. ; 48:4, s. 541-549
-
Journal article (peer-reviewed)abstract
- Background Poor self-rated health (SRH) at time of childbirth has been associated with adverse birth outcomes. However, it is not known whether prepregnancy SRH contributes to these outcomes or whether SRH is a proxy for some other factors. Therefore, the purpose of this study was to explore the associations between poor SRH before pregnancy and adverse birth outcomes. In addition, maternal characteristics associated with SRH before pregnancy were explored.Methods A population-based register study encompassing 261 731 deliveries in Sweden between January 2013 and July 2017 was conducted. The associations between poor SRH before pregnancy, rated at first antenatal visit, and the adverse birth outcomes of stillbirth, small for gestational age (SGA), and preterm birth were investigated with logistic regression analyses and presented as crude (OR) and adjusted odds ratios (aOR) with 95% confidence intervals (CI).Results Poor SRH before pregnancy was largely characterized by a history of psychiatric care and was associated with stillbirth (OR 1.37, 95% CI 1.04-1.79), SGA birth (OR 1.29, 95% CI 1.19-1.39), and preterm birth (OR 1.41, 95% CI 1.32-1.50). Adjusting for established risk factors for adverse birth outcomes, poor SRH remained associated with SGA birth (aOR 1.16, 95% CI 1.07-1.26) and preterm birth (aOR 1.25, 95% CI 1.17-1.33), but not with stillbirth (aOR 1.08, 95% CI 0.81-1.43).Conclusions SRH assessments could be used in early pregnancy to identify women in need of more extensive follow-up, as SRH appears to capture something beyond currently known risk factors for adverse birth outcomes.
