    Husband's role in handling pregnancy complications in Mangochi District, Malawi: A call for increased focus on community level male involvement2018In: Sexual & Reproductive HealthCare, ISSN 1877-5756, E-ISSN 1877-5764, Vol. 16, p. 61-66Article in journal (Refereed)
    Abstract [en]

    Objective: The objective of the current study is to provide information about husbands' role in decision-making and healthcare seeking in cases of pregnancy complications in Mangochi district, Malawi with an analysis of qualitative interviews using the concepts of "capital" and "field" from Bourdieu's social field theory. Study design: Twelve husbands and wives who had experienced pregnancy complications and six key informants from a semi-rural area of Mangochi district were interviewed individually. Thematic analysis was conducted based on the concepts of capital and field in Bourdieu's social field theory. Results: Husbands have significant economic and symbolic capital in decisions about healthcare seeking during instances of pregnancy complications as a result of their roles as father, head of the household and main income earner. Lack of money is the only acceptable reason for husbands to deny their wives healthcare. Husbands have limited access to knowledge of maternal health, which can compromise their decisions about seeking healthcare. Joint decision-making within families can be bypassed to allow for prompt healthcare seeking in emergencies. Conclusions: Husbands are important decision makers regarding seeking healthcare for pregnancy complications because of their economic and symbolic power and despite their limited access to knowledge of maternal health. Maternal healthcare seeking practices would benefit from wives gaining an empowered role as well as improved knowledge of maternal health among husbands.

    Elevated Plasma Levels of Arginines During Labor Among Women with Spontaneous Preterm Birth: A Prospective Cohort Study2024In: American Journal of Reproductive Immunology, ISSN 1046-7408, E-ISSN 1600-0897, Vol. 91, no 6, article id e13889Article in journal (Refereed)
    Abstract [en]

    Problem: Preterm birth (PTB) is a leading cause of infant mortality and morbidity. The pathogenesis of PTB is complex and involves many factors, including socioeconomy, inflammation and infection. Asymmetric dimethylarginine, ADMA and symmetric dimethylarginine, SDMA are involved in labor as inhibitors of nitric oxide, a known relaxant of the uterine smooth muscles. Arginines are scarcely studied in relation to PTB and we aimed to investigate arginines (ADMA, SDMA and L-arginine) in women with spontaneous PTB and term birth.

    Methods of the Study: The study was based on data from the population-based, prospective cohort BASIC study conducted in Uppsala County, Sweden, between September 2009 and November 2018. Arginines were analyzed by Ultra-High Performance Liquid Chromatography using plasma samples taken at the onset of labor from women with spontaneous PTB (n = 34) and term birth (n = 45). We also analyzed the inflammation markers CRP, TNF-R1 and TNF-R2 and GDF-15.

    Results: Women with spontaneous PTB had higher plasma levels of ADMA (p < 0.001), and L-Arginine (p = 0.03). In addition, inflammation marker, TNF-R1 (p = 0.01) was higher in spontaneous PTB compared to term birth. Further, in spontaneous PTB, no significant correlations could be observed when comparing levels of arginines with inflammation markers, except ADMA versus CRP.

    Conclusions: These findings provide novel evidence for the potential involvement of arginines in the pathogenesis of spontaneous PTB and it seems that arginine levels at labor vary independently of several inflammatory markers. Further research is warranted to investigate the potential of arginines as therapeutic targets in the prevention and management of spontaneous PTB.

    Plasma levels of arginines at term pregnancy in relation to mode of onset of labor and mode of childbirth2023In: American Journal of Reproductive Immunology, ISSN 1046-7408, E-ISSN 1600-0897, Vol. 90, no 3, article id e13767Article in journal (Refereed)
    Abstract [en]

    PROBLEM: The exact biochemical mechanisms that initiate labor are not yet fully understood. Nitric oxide is a potent relaxant of uterine smooth muscles until labor starts, and its precursor is L-arginine. Asymmetric (ADMA) and symmetric (SDMA) dimethylarginines, are potent NO-inhibitors. However, arginines (dimethylarginines and L-arginine) are scarcely studied in relation to labor and childbirth. We aimed to investigate arginines in women with spontaneous (SLVB) and induced (ILVB) term labor with vaginal birth and in women undergoing elective caesarean section (ECS).

    METHOD OF STUDY: Women at gestational week 16-18 were recruited to the population-based prospective cohort study BASIC at the Uppsala University Hospital, Sweden. Plasma samples taken at start of labor were analyzed for arginines, from SLVB (n = 45), ILVB (n = 45), and ECS (n = 45), using Ultra-High Performance Liquid Chromatography. Between-group differences were assessed using Kruskal-Wallis and Mann-Whitney U-test.

    RESULTS: Women with SLVB and ILVB had higher levels of ADMA (p < .0001), SDMA (p < .05) and lower L-arginines (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01, respectively <.001) compared to ECS. However, ILVB had higher ADMA (p < .0001) and lower L-arginine (p < .01), L-arginine/ADMA (p < .0001), and L-arginine/SDMA (p < .01) compared to SLVB. Results are adjusted for gestational length at birth and cervical dilatation at sampling.

    CONCLUSION: Our novel findings of higher levels of dimethylarginines in term vaginal births compared to ECS give insights into the biochemical mechanisms of labor. These findings might also serve as a basis for further studies of arginines in complicated pregnancies and labor.

    Maternal and Perinatal Outcomes in Singleton Nulliparous Spontaneous Preterm Birth with and without Preterm Premature Rupture of Membranes—A National Population-Based Cohort Study2024In: American Journal of Perinatology, ISSN 0735-1631, E-ISSN 1098-8785, Vol. 41, no S 01, p. e958-e967Article in journal (Refereed)
    Abstract [en]

    Objective Preterm birth (PTB, birth before 37 gestational weeks) is the leading cause of neonatal death and a major challenge for obstetric and neonatal care. About two-thirds of PTBs are spontaneous PTB (sPTB), of which approximately 30% start with preterm premature rupture of membranes (PPROM). The aim of the study was to investigate risk factors and maternal and perinatal outcomes in sPTB with and without PPROM.

    Study Design This is a national population-based cohort study including all singleton pregnancies in nulliparous women with spontaneous onset of labor and vaginal births (n = 266,968) registered in the Swedish Medical Birth Register 2005 to 2014. sPTB with PPROM (sPTB-PPROM) and sPTB without PPROM were compared regarding risk factors and maternal and perinatal outcomes. Logistic regression was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Adjustments were made for maternal age, body mass index, country of birth, smoking, chronic hypertension, pregestational and gestational diabetes, and gestational length.

    Results sPTB-PPROM (n = 5,037), compared with sPTB without PPROM (n = 8,426), was more common in women with previous spontaneous abortions, prepregnancy urinary tract infections, chronic hypertension, and gestational diabetes and had a higher risk of postpartum endometritis (aOR: 2.78, 95% CI: 1.55–5.00). Infants born to women with sPTB-PPROM had a lower risk of birth asphyxia (aOR: 0.60, 95% CI: 0.43–0.83), respiratory distress syndrome (aOR: 0.86, 95% CI: 0.70–1.00), retinopathy of prematurity (aOR: 0.93, 95% CI: 0.92–0.94), necrotizing enterocolitis (aOR: 0.95, 95% CI: 0.94–0.96), and higher risk of hypoglycemia (aOR: 1.14, 95% CI: 1.01–1.28), and hyperbilirubinemia (aOR: 1.28, 95% CI: 1.19–1.38) compared with infants born to sPTB without PPROM.

    Conclusion Our findings of risk factors and distinct differences in adverse outcomes after sPTB-PPROM compared with sPTB without PPROM are of vital importance and might serve as a basis when elaborating programs for the prevention and management of PPROM.

    Implications of Big Data Analytics, AI, Machine Learning, and Deep Learning in the Health Care System of Bangladesh: Scoping Review2024In: Journal of Medical Internet Research, E-ISSN 1438-8871, Vol. 26, article id e54710Article, review/survey (Refereed)
    Abstract [en]

    Background: The rapid advancement of digital technologies, particularly in big data analytics (BDA), artificial intelligence (AI), machine learning (ML), and deep learning (DL), is reshaping the global health care system, including in Bangladesh. The increased adoption of these technologies in health care delivery within Bangladesh has sparked their integration into health care and public health research, resulting in a noticeable surge in related studies. However, a critical gap exists, as there is a lack of comprehensive evidence regarding the research landscape; regulatory challenges; use cases; and the application and adoption of BDA, AI, ML, and DL in the health care system of Bangladesh. This gap impedes the attainment of optimal results. As Bangladesh is a leading implementer of digital technologies, bridging this gap is urgent for the effective use of these advancing technologies.

    Objective: This scoping review aims to collate (1) the existing research in Bangladesh’s health care system, using the aforementioned technologies and synthesizing their findings, and (2) the limitations faced by researchers in integrating the aforementioned technologies into health care research.

    Methods: MEDLINE (via PubMed), IEEE Xplore, Scopus, and Embase databases were searched to identify published research articles between January 1, 2000, and September 10, 2023, meeting the following inclusion criteria: (1) any study using any of the BDA, AI, ML, and DL technologies and health care and public health datasets for predicting health issues and forecasting any kind of outbreak; (2) studies primarily focusing on health care and public health issues in Bangladesh; and (3) original research articles published in peer-reviewed journals and conference proceedings written in English.

    Results: With the initial search, we identified 1653 studies. Following the inclusion and exclusion criteria and full-text review, 4.66% (77/1653) of the articles were finally included in this review. There was a substantial increase in studies over the last 5 years (2017-2023). Among the 77 studies, the majority (n=65, 84%) used ML models. A smaller proportion of studies incorporated AI (4/77, 5%), DL (7/77, 9%), and BDA (1/77, 1%) technologies. Among the reviewed articles, 52% (40/77) relied on primary data, while the remaining 48% (37/77) used secondary data. The primary research areas of focus were infectious diseases (15/77, 19%), noncommunicable diseases (23/77, 30%), child health (11/77, 14%), and mental health (9/77, 12%).

    Conclusions: This scoping review highlights remarkable progress in leveraging BDA, AI, ML, and DL within Bangladesh’s health care system. The observed surge in studies over the last 5 years underscores the increasing significance of AI and related technologies in health care research. Notably, most (65/77, 84%) studies focused on ML models, unveiling opportunities for advancements in predictive modeling. This review encapsulates the current state of technological integration and propels us into a promising era for the future of digital Bangladesh.

    Differences in head circumference and neuroimaging characteristics: what can they tell about the aetiologies of infant subdural haematoma?Manuscript (preprint) (Other academic)
    Abstract [en]

    Background Acute (ASDH) and chronic subdural haematoma (CSDH) in infants have been regarded as highly specific for abuse. A recent study showed different risk factors for ASDH and CSDH, indicating that CSDH in many cases was related to external hydrocephalus. 

    Purpose To investigate to what extent external hydrocephalus may explain findings and symptoms interpreted as signs of abusive head trauma. 

    Material and methods Eighty-five infants with ASDH (n=16) and CSDH (n=69) were reviewed with regard to cranio-cortical- (CCW), sino-cortical- (SCW), frontal interhemispheric-(IHW), subarachnoid space width (SSW) and head circumference (HC). In infants with unilateral SDH, the correlation between the contralateral SSW and the ipsilateral CCW and SDH width was calculated. A correlation would imply that the CSDH replaces an already existing extracerebral space.

    Results Infants with CSDH had significantly higher CCW, SCW, IHW and SSW than infants with ASDH (p < 0.05). The ipsilateral CCW (R = 0.92, p < 0.001) and SDH width (R = 0.81, p < 0.01) were correlated to the contralateral SSW. Increased HC was more prevalent in Infants with CSDH (71%) than in infants with ASDH (14%) (p < 0.01). Forty-two infants, all with CSDH, had at least one of CCW, SCW or IHW ≥ 95th percentile. Twenty infants, all with CSDH, had CCW, SCW and IHW > 5 mm and increased HC. 

    Conclusion A significant proportion of infants with CSDH may have external hydrocephalus as an underlying cause and that parts of the widened subarachnoid space in some infants is replaced by a CSDH.

    Different vulnerability profiles in acute compared to chronic subdural haematoma amongst infants with suspected abusive head traumaManuscript (preprint) (Other academic)
    Abstract [en]

    Background: In a register study based on ICD 10 coding, there was a similar vulnerability profile (male sex, preterm and small for gestational age) in infants diagnosed with non-traumatic subdural haematoma (SDH) and infants having SDH with abuse diagnosis. However, ICD-10 does not separate between acute (ASDH) and chronic subdural haematoma (CSDH). 

    Purpose: To determine the vulnerability profile in infants having CSDH and ASDH, respectively. 

    Material and methods: A descriptive review of infants with SDH/hygroma examined by the Swedish National Board of Forensic Medicine between 1994 and 2018. Included cases (n=85) were analysed with regard to possible vulnerability factors. 

    Results: Type of subdural fluid could be determined in 85 of 96 cases. Sixteen infants had ASDH and 69 CSDH. Infants with ASDH had the peak incidence during the first month of life, 56% were male, 6% were premature, 13% were twins and 44% died. In infants with CSDH, the peak incidence occurred during the third month of life, 69% were male, 34% were premature, 12% were twins and 4% died. 

    Conclusion: CSDH, but not ASDH, is associated with factors suggesting non-traumatic pathogenesis, for which reason CSDH and ASDH should be analysed separately to extend the knowledge regarding the aetiology of SDH during infancy.

    External Hydrocephalus as a Cause of Infant Subdural Hematoma: Epidemiological and Radiological Investigations of Infants Suspected of Being Abused.2021In: Pediatric Neurology, ISSN 0887-8994, E-ISSN 1873-5150, Vol. 126, p. 26-34, article id S0887-8994(21)00212-5Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Acute subdural hematoma (ASDH) and chronic subdural hematoma (CSDH) in infants have been regarded as highly specific for abuse. Other causes of CSDH have not been investigated in a large population.

    PURPOSE: The purpose of this study was to investigate to what extent external hydrocephalus is present in infants with ASDH and CSDH undergoing evaluation for abuse.

    MATERIAL AND METHODS: Eighty-five infants suspected of being abused, with ASDH (n = 16) or CSDH (n = 69), were reviewed regarding age, risk factor profiles, craniocortical width (CCW), sinocortical width (SCW), frontal interhemispheric width (IHW), subarachnoid space width (SSW), and head circumference (HC). In infants with unilateral subdural hematoma (SDH), correlations between contralateral SSW and ipsilateral CCW and SDH width were investigated.

    RESULTS: Infants with CSDH had significantly lower mortality, were more often premature and male, and had significantly higher CCW, SCW, IHW, and SSW than infants with ASDH (P < 0.05). Ipsilateral CCW (R = 0.92, P < 0.001) and SDH width (R = 0.81, P < 0.01) correlated with contralateral SSW. Increased HC was more prevalent in infants with CSDH (71%) than in infants with ASDH (14%) (P < 0.01). Forty-two infants, all with CSDH, had at least one of CCW, SCW, or IHW ≥95th percentile. Twenty infants, all with CSDH, had CCW, SCW, and IHW >5 mm, in addition to increased HC.

    CONCLUSION: A substantial proportion of infants with CSDH who had been suspected of being abused had findings suggesting external hydrocephalus.

    Predicting women with depressive symptoms postpartum with machine learning methods2021In: Scientific Reports, E-ISSN 2045-2322, Vol. 11, no 1, article id 7877Article in journal (Refereed)
    Abstract [en]

    Postpartum depression (PPD) is a detrimental health condition that affects 12% of new mothers. Despite negative effects on mothers' and children's health, many women do not receive adequate care. Preventive interventions are cost-efficient among high-risk women, but our ability to identify these is poor. We leveraged the power of clinical, demographic, and psychometric data to assess if machine learning methods can make accurate predictions of postpartum depression. Data were obtained from a population-based prospective cohort study in Uppsala, Sweden, collected between 2009 and 2018 (BASIC study, n = 4313). Sub-analyses among women without previous depression were performed. The extremely randomized trees method provided robust performance with highest accuracy and well-balanced sensitivity and specificity (accuracy 73%, sensitivity 72%, specificity 75%, positive predictive value 33%, negative predictive value 94%, area under the curve 81%). Among women without earlier mental health issues, the accuracy was 64%. The variables setting women at most risk for PPD were depression and anxiety during pregnancy, as well as variables related to resilience and personality. Future clinical models that could be implemented directly after delivery might consider including these variables in order to identify women at high risk for postpartum depression to facilitate individualized follow-up and cost-effectiveness.

    Coping Strategies of Norwegian Healthcare Professionals Facing Perinatal Death: A Qualitative Study2019In: International Journal of Childbirth, ISSN 2156-5287, E-ISSN 2156-5295, Vol. 9, no 3, p. 107-119Article in journal (Refereed)
    Abstract [en]

    AIM: Perinatal death is often regarded as a critical incident for the healthcare personnel involved. How healthcare personnel respond to traumatic events in their work is a function of their level of awareness or exposure to the incident, as well as their genuine expectations, support, and trust. The aim of this study was to explore coping strategies of Norwegian healthcare professionals including midwifes, obstetricians, and assistant nurses when faced with perinatal death in a clinical setting.

    METHOD: Midwives, obstetricians, and assistant nurses in two public hospitals in Norway participated in an in-depth and semi-structured interview. The data was analyzed using Kvale's approach, which involves condensing and thematic analysis.

    FINDINGS: The results are divided into three categories with eight subcategories. Having the support of one's colleagues was described as an important factor for coping with these situations. Both immediate support in the situation and talking about their feelings later with colleagues were found to be important. Discussing and sharing responsibility were also mentioned.

    CONCLUSION: Informants in this study stated that talking with one another about the challenges they faced in these situations was important. Appropriate education and training programs, together with healthy coping and debriefing strategies must be implemented in maternity units.

    Characteristics of good contraceptive counselling: An interview study2024In: Sexual & Reproductive HealthCare, ISSN 1877-5756, E-ISSN 1877-5764, Vol. 39, article id 100948Article in journal (Refereed)
    Abstract [en]

    Objective

    One key component in preventing unplanned pregnancies is to provide effective contraceptive counselling. This study aimed to investigate what characterises good contraceptive counselling from the woman's perspective.

    Methods

    A qualitative study with a phenomenological approach. Twenty-four women aged 15–45 participated in semi-structured, individual, face-to-face interviews that lasted, on average, one hour. Data were analysed by latent content analysis.

    Results

    One overall theme emerged, person-centred contraceptive counselling – an interactive process, with three main categories: (i) a trustworthy healthcare provider, (ii) creating a liaison and (iii) the right time and place.

    Conclusions

    The healthcare provider’s attributes as well as what happened between the healthcare provider and the woman, and the surrounding context, had a bearing on the women’s descriptions of good contraceptive counselling. The process of the counselling was described as more important than the actual outcome; thus, healthcare providers need to be aware that this seemingly straightforward consultation is rather multi-layered and has great health promoting potential.

    A longitudinal multi-centric cohort study assessing infant neurodevelopment delay among women with persistent postpartum depression in Nepal2024In: BMC Medicine, E-ISSN 1741-7015, Vol. 22, no 1, article id 284Article in journal (Refereed)
    Abstract [en]

    Background

    Infant neurodevelopment in the first years after birth is determined by multiple factors, including parental care and maternal mental wellbeing. In this study, we aim to assess the impact of persistent maternal depressive symptoms during the first 3 months postpartum on infant neurodevelopment at 6 months.

    Methods

    Using a longitudinal cohort design, 1253 mother-infant pairs were followed up at 7, 45, and 90 days to assess postpartum depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS); infants were followed up at 6 months to assess neuro-developmental status using the WHO's Infant and Young Child Development (IYCD) tool. A generalized linear regression model was used to assess the association between persistent postpartum depressive symptoms and infant neurodevelopmental delay at 6 months. A generalized linear mixed model (GLMM) with a hospital as a random intercept was used to assess the persistent postpartum depressive symptoms with an IYCD score. Linear regression was used to compare the IYCD scores between exposure groups.

    Results

    In the study population, 7.5% of mothers had persistent depressive symptoms, and 7.5% of infants had neurodevelopmental delay. Infants born to mothers with persistent depressive symptoms had a higher proportion of neurodevelopmental delay than infants born to women without persistent symptoms (48.6% vs 5.1%; p < 0.001). In the adjusted regression model, infants whose mothers had persistent depressive symptoms at 7, 45, and 90 days had a 5.21-fold increased risk of neurodevelopmental delay (aRR, 5.21; 95% CI, 3.17, 8.55). Mean scores in the motor domain (12.7 vs 15.2; p < 0.001) and language domain (6.4 vs 8.5; p < 0.001) were significant when a mother had persistent depression vs. no depression. Mean scores in the general behavioral domain (5.9 vs 10.4, p < 0.001) and the socio-emotional domain (15.4 vs 17.7; p < 0.001) were significantly different when a mother had persistent depression vs no persistent depression.

    Conclusions

    Our results suggest that 6-month-old infants are at higher risk for neurodevelopment delays if their mother reports persistent symptoms of depression from 7 to 90 days postpartum. The neurodevelopmental delay can be observed in all functional domains. Preventive intervention to reduce maternal postpartum depression may reduce the impact on infant developmental delay.

    Severe obstetric lacerations associated with postpartum depression among women with low resilience: a Swedish birth cohort study2020In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 127, no 11, p. 1382-1390Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: Women's levels of resilience and attitudes towards perineal lacerations vary greatly. Some women see them as part of the birthing process, while others react with anger, depressed mood or even self-harm thoughts. A previous study has reported increased risk of postpartum depressive (PPD) symptoms in women with severe perineal lacerations. The aim of this study was to assess the association between severe obstetric perineal lacerations and PPD. A secondary objective was to assess this association among women with low resilience.

    DESIGN: Nested cohort study.

    SETTING: Uppsala, Sweden.

    SAMPLE: Vaginally delivered women with singleton pregnancies (n = 2,990).

    METHODS: The main exposure was obstetric perineal lacerations. Resilience was assessed in gestational week 32 using the Swedish version of the Sense of Coherence Scale (SOC-29). A digital acyclic graph (DAG) was used to identify possible confounders and mediators. Logistic regression was used to estimate odds ratios and 95% confidence intervals. A sub-analysis was run after excluding women with normal or high resilience.

    MAIN OUTCOME MEASURES: Postpartum depression, assessed with the Depression Self-Reporting Scale (DSRS), completed at six weeks postpartum.

    RESULTS: There was no significant association between severe obstetric perineal lacerations and PPD at six weeks postpartum. However, a significant association was found between severe lacerations and PPD in women with low resilience (OR =4.8 95% CI = 1.2-20), persisting even after adjusting for confounding factors.

    CONCLUSION: Health care professionals might need to identify women with low resilience, as they are at increased risk for PPD after a severe perineal laceration.

    Alcohol exposure prior to pregnancy-does hazardous consumption affect placenta- and inflammatory-mediated pregnancy outcomes? A Swedish population-based cohort study2022In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 101, no 12, p. 1386-1394Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Alcohol consumption during pregnancy is related to severe birth complications such as low birthweight, preterm birth and birth defects. During the last decade, the Alcohol Use Disorders Identification Test (AUDIT) has been used as a screening tool in Swedish maternal healthcare units to identify hazardous, pre-pregnancy alcohol use. However, evaluation of the screening with AUDIT, as well as adverse maternal or neonatal outcomes, has not been assessed at a national level.

    MATERIAL AND METHODS: This was a population-based cohort study of 530 458 births from 2013 to 2018 using demographic, reproductive and maternal health data from the Swedish Pregnancy Register. Self-reported alcohol consumption in the year before pregnancy, measured as AUDIT scores, was categorized into moderate (6-13 points) and high-risk (14-40 points) consumption, with low-risk (0-5 points) consumption as the reference group. Associations with pregnancy- and birth outcomes were explored with logistic regressions using generalized estimating equation models, adjusting for maternal and socioeconomic characteristics. Estimates are presented as adjusted odds ratios (aORs) with 95% confidence intervals (CIs).

    RESULTS: High-risk and moderate pre-pregnancy alcohol consumption was associated with preeclampsia, preterm birth and birth of an infant small for gestational age (SGA), but these associations were nonsignificant after adjustments. Prior moderate-risk (aOR 1.29, 95% CI 1.17-1.42) and high-risk consumption (aOR 1.62, 95% CI 1.17-2.25) increased the likelihood of intrapartum and neonatal infections.

    CONCLUSIONS: Apart from identifying hazardous alcohol consumption prior to pregnancy and the offer of counseling, screening with the AUDIT in early pregnancy indicates a high risk of inflammatory-/placenta-mediated pregnancy and birth outcomes. For most outcomes, AUDIT was not an independent contributor when adjusting for confounding factors. Hazardous alcohol use prior to pregnancy was independently linked to intrapartum and neonatal infections; conditions associated with morbidity and long-term sequalae. These associations may be explained by alcohol-induced changes in the maternal or fetal immune system in early pregnancy or persistent alcohol intake during pregnancy, or may depend on unidentified confounding factors.

    Evolutionary history of endogenous Human Herpesvirus 6 reflects human migration out of Africa2021In: Molecular biology and evolution, ISSN 0737-4038, E-ISSN 1537-1719, Vol. 38, no 1, p. 96-107Article in journal (Refereed)
    Abstract [en]

    Human herpesvirus 6A and 6B (HHV-6) can integrate into the germline, and as a result about 70 million people harbour the genome of one of these viruses in every cell of their body. Until now, it has been largely unknown if i) these integrations are ancient, ii) if they still occur, and iii) whether circulating virus strains differ from integrated ones. Here we used next generation sequencing and mining of public human genome datasets to generate the largest and most diverse collection of circulating and integrated HHV-6 genomes studied to date. In genomes of geographically dispersed, only distantly-related people, we identified clades of integrated viruses that originated from a single ancestral event, confirming this with fluorescent in situ hybridization to directly observe the integration locus. In contrast to HHV-6B, circulating and integrated HHV-6A sequences form distinct clades, arguing against ongoing integration of circulating HHV-6A or "reactivation" of integrated HHV-6A. Taken together, our study provides the first comprehensive picture of the evolution of HHV-6, and reveals that integration of heritable HHV-6 has occurred since the time of, if not before, human migrations out of Africa.

    Cohort profile: the Biology, Affect, Stress, Imaging and Cognition (BASIC) study on perinatal depression in a population-based Swedish cohort2019In: BMJ Open, E-ISSN 2044-6055, Vol. 9, no 10, article id e031514Article in journal (Refereed)
    Abstract [en]

    PURPOSE: With the population-based, prospective Biology, Affect, Stress, Imaging and Cognition (BASIC) cohort, we aim to investigate the biopsychosocial aetiological processes involved in perinatal depression (PND) and to pinpoint its predictors in order to improve early detection.

    PARTICIPANTS: From September 2009 to November 2018, the BASIC study at Uppsala University Hospital, Sweden, has enrolled 5492 women, in 6478 pregnancies, of which 46.3% first-time pregnancies and with an average age of 31.5 years. After inclusion around gestational week 16-18, participants are followed-up with data collection points around gestational week 32, at childbirth, as well as three times postpartum: after 6 weeks, 6 months and 1 year. At the last follow-up, 70.8% still remain in the cohort.

    FINDINGS TO DATE: In addition to internet-based surveys with self-report instruments, participants contribute with biological samples, for example, blood samples (maternal and from umbilical cord), biopsies (umbilical cord and placenta) and microbiota samples. A nested case-control subsample also takes part in cognitive and emotional tests, heart rate variability tests and bioimpedance tests. Subprojects have identified various correlates of PND of psychological and obstetric origin in addition to factors of the hypothalamic-pituitary-adrenal axis and immune system.

    FUTURE PLANS: In parallel with the completion of data collection (final follow-up November 2019), BASIC study data are currently analysed in multiple subprojects. Since 2012, we are conducting an ongoing follow-up study on the participants and their children up to 6 years of age (U-BIRTH). Researchers interested in collaboration may contact Professor Alkistis Skalkidou (corresponding author) with their request to be considered by the BASIC study steering committee.

    Investigating the association between neuroticism and adverse obstetric and neonatal outcomes2019In: Scientific Reports, E-ISSN 2045-2322, Vol. 9, article id 15470Article in journal (Refereed)
    Abstract [en]

    Neuroticism is not only associated with affective disorders but also with certain somatic health problems. However, studies assessing whether neuroticism is associated with adverse obstetric or neonatal outcomes are scarce. This observational study comprises first-time mothers (n = 1969) with singleton pregnancies from several cohorts based in Uppsala, Sweden. To assess neuroticism-related personality, the Swedish universities Scales of Personality was used. Swedish national health registers were used to extract outcomes and confounders. In logistic regression models, odds ratios (ORs) with 95% confidence intervals (Cis) were calculated for the outcomes by an increase of 63 units of neuroticism (equalling the interquartile range). Analyses were adjusted for maternal age, educational level, height, body mass index, year of delivery, smoking during pregnancy, involuntary childlessness, and psychiatric morbidity. Main outcomes were mode of delivery, gestational diabetes mellitus, gestational hypertension, preeclampsia, induction of delivery, prolonged delivery, severe lacerations, placental retention, postpartum haemorrhage, premature birth, infant born small or large for gestational age, and Apgar score. Neuroticism was not independently associated with adverse obstetric or neonatal outcomes besides gestational diabetes. For future studies, models examining sub-components of neuroticism or pregnancy-specific anxiety are encouraged.

    Neuroticism is associated with higher antenatal care utilization in obstetric low-risk women2019In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 98, no 4, p. 470-478Article in journal (Refereed)
    Abstract [en]

    Introduction

    Elevated neuroticism is associated with higher health care utilization in the general population. This study aimed to investigate the association between neuroticism and the use of publicly financed antenatal care in obstetric low‐risk women, taking predisposing and need factors for health care utilization into consideration.

    Material and methods

    Participants comprised 1052 obstetric low‐risk women (no chronic diseases or adverse pregnancy conditions) included in several obstetrics/gynecology studies in Uppsala, Sweden. Neuroticism was self‐rated on the Swedish universities Scales of Personality. Medical records of their first subsequent pregnancy were scanned for antenatal care use. Associations between antenatal care use and neuroticism were analyzed with logistic regression (binary outcomes) or negative binomial regression (count outcomes) comparing the 75th and 25th neuroticism percentiles. Depending on the Akaike information criterion the exposure was modeled as either linear or with restricted cubic splines. Analyses were adjusted for predisposing (sociodemographic and parity) and need factors (body mass index and psychiatric morbidity).

    Results

    After adjustment, women with higher neuroticism had more fetal ultrasounds (incidence rate ratio = 1.09, 95% confidence interval (CI) 1.02‐1.16), more emergency visits to an obstetrician/gynecologist (incidence rate ratio = 1.22, 95% CI 1.03‐1.45) and were more likely to visit a fear‐of‐childbirth clinic (odds ratio = 2.71, 95% CI 1.71‐4.29). Moreover, they more often consulted midwives in specialized antenatal care facilities (significant J‐shaped association).

    Conclusions

    Neuroticism was associated with higher utilization of publicly financed antenatal care in obstetric low‐risk women, even after adjusting for predisposing and need factors. Future studies should address the benefits of interventions as a complement to routine antenatal care programs to reduce subclinical anxiety.

    Association between convalescent plasma treatment and mortality in COVID-19: a collaborative systematic review and meta-analysis of randomized clinical trials2021In: BMC Infectious Diseases, E-ISSN 1471-2334, Vol. 21, no 1, article id 1170Article, review/survey (Refereed)
    Abstract [en]

    Background: Convalescent plasma has been widely used to treat COVID-19 and is under investigation in numerous randomized clinical trials, but results are publicly available only for a small number of trials. The objective of this study was to assess the benefits of convalescent plasma treatment compared to placebo or no treatment and all-cause mortality in patients with COVID-19, using data from all available randomized clinical trials, including unpublished and ongoing trials (Open Science Framework, ). Methods: In this collaborative systematic review and meta-analysis, clinical trial registries (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform), the Cochrane COVID-19 register, the LOVE database, and PubMed were searched until April 8, 2021. Investigators of trials registered by March 1, 2021, without published results were contacted via email. Eligible were ongoing, discontinued and completed randomized clinical trials that compared convalescent plasma with placebo or no treatment in COVID-19 patients, regardless of setting or treatment schedule. Aggregated mortality data were extracted from publications or provided by investigators of unpublished trials and combined using the Hartung-Knapp-Sidik-Jonkman random effects model. We investigated the contribution of unpublished trials to the overall evidence. Results: A total of 16,477 patients were included in 33 trials (20 unpublished with 3190 patients, 13 published with 13,287 patients). 32 trials enrolled only hospitalized patients (including 3 with only intensive care unit patients). Risk of bias was low for 29/33 trials. Of 8495 patients who received convalescent plasma, 1997 died (23%), and of 7982 control patients, 1952 died (24%). The combined risk ratio for all-cause mortality was 0.97 (95% confidence interval: 0.92; 1.02) with between-study heterogeneity not beyond chance (I-2 = 0%). The RECOVERY trial had 69.8% and the unpublished evidence 25.3% of the weight in the meta-analysis. Conclusions: Convalescent plasma treatment of patients with COVID-19 did not reduce all-cause mortality. These results provide strong evidence that convalescent plasma treatment for patients with COVID-19 should not be used outside of randomized trials. Evidence synthesis from collaborations among trial investigators can inform both evidence generation and evidence application in patient care.

    Published registry-based pharmacoepidemiologic associations show limited concordance with agnostic medication-wide analyses2023In: Journal of Clinical Epidemiology, ISSN 0895-4356, E-ISSN 1878-5921, Vol. 160, p. 33-45Article in journal (Refereed)
    Abstract [en]

    Objectives: To assess how the results of published national registry-based pharmacoepidemiology studies (where select associations are of interest) compare with an agnostic medication-wide approach (where all possible drug associations are tested).

    Study Design and Setting: We systematically searched for publications that reported drug associations with any, breast, colon/colorectal, or prostate cancer in the Swedish Prescribed Drug Registry. Results were compared against a previously performed agnostic medication-wide study on the same registry. Protocol: https://osf.io/kqj8n.

    Results: Most published studies (25/32) investigated previously reported associations. 421/913 (46%) associations had statistically significant results. 134 of the 162 unique drug-cancer associations could be paired with 70 associations in the agnostic study (corresponding drug categories and cancer types). Published studies reported smaller effect sizes and absolute effect sizes than the agnostic study, and generally used more adjustments. Agnostic analyses were less likely to report statistically significant protective associations (based on a multiplicity-corrected threshold) than their paired associations in published studies (McNemar odds ratio 0.13, P = 0.0022). Among 162 published associations, 36 (22%) showed increased risk signal and 25 (15%) protective signal at P < 0.05, while for agnostic associations, 237 (11%) showed increased risk signal and 108 (5%) protective signal at a multiplicity-corrected threshold. Associations belonging to drug categories targeted by individual published studies vs. nontargeted had smaller average effect sizes; smaller P values; and more frequent risk signals.

    Conclusion: Published pharmacoepidemiology studies using a national registry addressed mostly previously proposed associations, were mostly “negative”, and showed only modest concordance with their respective agnostic analyses in the same registry.

    Differential COVID-19 infection rates in children, adults, and elderly: Systematic review and meta-analysis of 38 pre-vaccination national seroprevalence studies2023In: Journal of Global Health, ISSN 2047-2978, E-ISSN 2047-2986, Vol. 13, article id 06004Article, review/survey (Refereed)
    Abstract [en]

    Background

    Debate exists about whether extra protection of elderly and other vulnerable individuals is feasible in COVID-19. We aimed to assess the relative infection rates in the elderly vs the non-elderly and, secondarily, in children vs adults.

    Methods

    We performed a systematic review and meta-analysis of seroprevalence studies conducted in the pre-vaccination era. We identified representative national studies without high risk of bias through SeroTracker and PubMed searches (last updated May 17, 2022). We noted seroprevalence estimates for children, non-elderly adults, and elderly adults, using cut-offs of 20 and 60 years (or as close to these ages, if they were unavailable) and compared them between different age groups.

    Results

    We included 38 national seroprevalence studies from 36 different countries comprising 826 963 participants. Twenty-six of these studies also included pediatric populations and twenty-five were from high-income countries. The median ratio of seroprevalence in elderly vs non-elderly adults (or non-elderly in general, if pediatric and adult population data were not offered separately) was 0.90-0.95 in different analyses, with large variability across studies. In five studies (all in high-income countries), we observed significant protection of the elderly with a ratio of <0.40, with a median of 0.83 in high-income countries and 1.02 elsewhere. The median ratio of seroprevalence in children vs adults was 0.89 and only one study showed a significant ratio of <0.40. The main limitation of our study is the inaccuracies and biases in seroprevalence studies.

    Conclusions

    Precision shielding of elderly community-dwelling populations before the availability of vaccines was indicated in some high-income countries, but most countries failed to achieve any substantial focused protection.

    Mortality outcomes with hydroxychloroquine and chloroquine in COVID-19 from an international collaborative meta-analysis of randomized trials2021In: Nature Communications, E-ISSN 2041-1723, Vol. 12, no 1, article id 2349Article in journal (Refereed)
    Abstract [en]

    Substantial COVID-19 research investment has been allocated to randomized clinical trials (RCTs) on hydroxychloroquine/chloroquine, which currently face recruitment challenges or early discontinuation. We aim to estimate the effects of hydroxychloroquine and chloroquine on survival in COVID-19 from all currently available RCT evidence, published and unpublished. We present a rapid meta-analysis of ongoing, completed, or discontinued RCTs on hydroxychloroquine or chloroquine treatment for any COVID-19 patients (protocol: https://osf.io/QESV4/). We systematically identified unpublished RCTs (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Cochrane COVID-registry up to June 11, 2020), and published RCTs (PubMed, medRxiv and bioRxiv up to October 16, 2020). All-cause mortality has been extracted (publications/preprints) or requested from investigators and combined in random-effects meta-analyses, calculating odds ratios (ORs) with 95% confidence intervals (CIs), separately for hydroxychloroquine and chloroquine. Prespecified subgroup analyses include patient setting, diagnostic confirmation, control type, and publication status. Sixty-three trials were potentially eligible. We included 14 unpublished trials (1308 patients) and 14 publications/preprints (9011 patients). Results for hydroxychloroquine are dominated by RECOVERY and WHO SOLIDARITY, two highly pragmatic trials, which employed relatively high doses and included 4716 and 1853 patients, respectively (67% of the total sample size). The combined OR on all-cause mortality for hydroxychloroquine is 1.11 (95% CI: 1.02, 1.20; I-2=0%; 26 trials; 10,012 patients) and for chloroquine 1.77 (95%CI: 0.15, 21.13, I-2=0%; 4 trials; 307 patients). We identified no subgroup effects. We found that treatment with hydroxychloroquine is associated with increased mortality in COVID-19 patients, and there is no benefit of chloroquine. Findings have unclear generalizability to outpatients, children, pregnant women, and people with comorbidities. Hydroxychloroquine and chloroquine have been investigated as a potential treatment for Covid-19 in several clinical trials. Here the authors report a meta-analysis of published and unpublished trials, and show that treatment with hydroxychloroquine for patients with Covid-19 was associated with increased mortality, and there was no benefit from chloroquine.

    Psychometric properties of the attachment style questionnaire in Swedish pregnant women: short and full versions2017In: Journal of Reproductive and Infant Psychology, ISSN 0264-6838, E-ISSN 1469-672X, Vol. 35, no 5, p. 450-461Article in journal (Refereed)
    Abstract [en]

    Objectives: (i) To evaluate the reliability and factor structure of the Attachment Style Questionnaire – Short Form (ASQ-SF) for use in pregnant women and (ii) to compare the reliability and factor structure of the short- and full version-ASQ among pregnant women. Background: Adult attachment insecurity is currently included as a major risk factor in studies of perinatal health. None of the self-report measures with a Swedish translation have been psychometrically evaluated in a pregnant cohort.

    Methods: A population-based cohort of 1631 pregnant women answered the ASQ in late pregnancy. Internal consistency (item- subscale correlations, Cronbach’s α, and α if item deleted) was evaluated for the seven available subscales. Con rmatory factor analysis (CFA) was run to examine the factor structure of the short form compared with the full-version. Test–retest correlations were assessed in a subgroup (n = 48).

    Results: All mean item-subscale correlations for the ASQ-SF were > 0.30. Cronbach’s α’s for ASQ-SF dimensions were as follows: Avoidance (0.87); Anxiety (0.89); Discomfort with Closeness (0.85); Relationships as Secondary (0.54); Con dence (0.83); Need for Approval (0.76); and Preoccupation with Relationships (0.77). No item removal substantively increased subscale α’s. The CFA demonstrated better model t for the ASQ-SF than for the full-version ASQ, while other reliability measures were similar. Test–retest correlations ranged from 0.65 to 0.84.

    Conclusion: The ASQ-SF showed similar psychometric properties in pregnant women as in the general population and had good reliability, but the optimal factor structure needs to be studied further. Results support the usage of the ASQ-SF in pregnant cohorts.

    Pre-pregnancy participation and performance in world's largest cross-country ski race as a proxy for physical exercise and fitness, and perinatal outcomes: Prospective registry-based cohort study2023In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 130, no 8, p. 891-901Article in journal (Refereed)
    Abstract [en]

    Objective: Investigate associations between pre-pregnancy participation and performance in a demanding cross-country ski race (proxy for exercise volume and fitness) and perinatal outcomes. Pre-registered protocol: osf.io/aywg2.

    Design: Prospective cohort study.

    Setting: Based on entire overlap between the Vasaloppet registry and the population-based Swedish Pregnancy Register.

    Sample: All female Vasaloppet participants 1991-2017 with subsequent singleton delivery (skiers), and age- and county-matched non-skiers.

    Methods: We calculated odds ratios (ORs) for non-skiers versus skiers (model 1) and, among skiers, by performance (model 2), in Bayesian logistic regressions adjusted for socio-demographics, lifestyle factors, and comorbidities. We repeated calculations adjusting for early pregnancy body mass index (potential mediator) and explored robustness (selection/exposure settings; multiple comparisons correction).

    Main outcome measures: Twenty-nine important perinatal outcomes, predefined based on existing expert consensus.

    Results: Non-skiers (n = 194 384) versus skiers (n = 15 377) (and slower versus faster performance, not shown) consistently had higher odds of gestational diabetes mellitus (GDM) (OR 1.70, 95% highest density interval: 1.40-2.09), excessive gestational weight gain (GWG) (1.28, 1.22-1.38), psychiatric morbidity (1.60, 1.49-1.72), any caesarean section (CS) (1.34, 1.28-1.40), elective CS (1.39, 1.29-1.49), and large-for-gestational-age babies (> 90th percentile, 1.11, 1.04-1.18); lower odds of inadequate GWG (0.83, 0.79-0.88); and no associations with fetal/neonatal complications (e.g. preterm birth [1.09, 0.98-1.20], small for gestational age [SGA] [1.23, 1.05-1.45]). Adjustment for body mass index attenuated associations with excessive (1.20, 1.14-1.30) and inadequate GWG (0.87, 0.83-0.92) and large for gestational age (1.07, 1.00-1.13).

    Conclusion: Non-skiers compared with skiers, and slower versus faster performance, consistently displayed higher odds of GDM, excessive GWG, psychiatric morbidity, CS and large-for-gestational-age babies; and lower odds of inadequate GWG, after adjustment for socio-demographic and lifestyle factors and comorbidities. There were no associations with fetal/neonatal complications.

    Pregnancy and postpartum psychiatric episodes in fathers: A population-based study on treatment incidence and prevalence2022In: Journal of Affective Disorders, ISSN 0165-0327, E-ISSN 1573-2517, Vol. 296, p. 130-135Article in journal (Refereed)
    Abstract [en]

    Background

    For women, the perinatal period confers an increased risk of severe psychiatric disorders, but similar evidence for fathers is lacking. We examined rates of first-time and recurrent psychiatric disorders in men before and after becoming fathers.

    Methods

    A descriptive prospective study design was applied using information from the Danish National registers. Perinatal psychiatric episodes were assessed as incidence of first-time and prevalence (including recurrence) of recorded in- or outpatient admissions for any mental disorder and redeemed prescriptions for psychotropic medication in fathers to children born from January 1, 1998 until December 31, 2015.

    Results

    We identified 929,415 births and 543,555 unique fathers. Incidence and prevalence proportions for paternal psychiatric in- and outpatient episodes showed an increasing trend over the perinatal period and were marginally higher postpartum compared to pregnancy; e.g., median incidence proportion for inpatient treatment during pregnancy was 0.07 (95% CI: 0.04; 0.07) and 0.10 (95% CI: 0.08; 0.11) postpartum per 1000 births. No difference between the periods was found for incidence of prescriptions for psychotropic medication. Psychiatric disorders in expecting and new fathers were mainly treated in primary care with cumulative incidence of prescriptions for psychotropic medication of 14.56 per 1000 births during the first year of fatherhood.

    Limitations

    We only capture fathers who actively sought and received treatment, and we consequently underestimate milder psychiatric episodes in expecting and new fathers.

    Conclusion

    Becoming a father did not appear to trigger a substantially increased risk of severe psychiatric disorders, as it has been observed for new mothers.

    Investigations of microbiota composition and neuroactive pathways in association with symptoms of stress and depression in a cohort of healthy women2024In: Frontiers in Cellular and Infection Microbiology, E-ISSN 2235-2988, Vol. 14, article id 1324794Article in journal (Refereed)
    Abstract [en]

    Background: Despite mounting evidence of gut-brain involvement in psychiatric conditions, functional data remain limited, and analyses of other microbial niches, such as the vaginal microbiota, are lacking in relation to mental health. This aim of this study was to investigate if the connections between the gut microbiome and mental health observed in populations with a clinical diagnosis of mental illness extend to healthy women experiencing stress and depressive symptoms. Additionally, this study examined the functional pathways of the gut microbiota according to the levels of psychological symptoms. Furthermore, the study aimed to explore potential correlations between the vaginal microbiome and mental health parameters in young women without psychiatric diagnoses.

    Methods: In this cross-sectional study, 160 healthy Danish women (aged 18-40 years) filled out questionnaires with validated scales measuring symptoms of stress and depression and frequency of dietary intake. Fecal and vaginal microbiota samples were collected at the beginning of the menstrual cycle and vaginal samples were also collected at cycle day 8-12 and 18-22. Shotgun metagenomic profiling of the gut and vaginal microbiome was performed. The Kyoto Encyclopedia of Genes and Genomes (KEGG) was used for functional profiling and 56 Gut Brain Modules were analyzed in the fecal samples.

    Results: The relative abundance in the gut of the genera Escherichia, Parabacteroides, and Shigella was higher in women with elevated depressive symptoms. Women with high perceived stress showed a tendency of increased abundance of Escherichia, Shigella, and Blautia. Amongst others, the potentially pathogenic genera, Escherichia and Shigella correlate with alterations in the neuroactive pathways such as the glutamatergic, GABAeric, dopaminergic, and Kynurenine pathways. Vaginosis symptoms were more prevalent in women reporting high levels of stress and depressive symptoms.

    Conclusions: The findings of this study support the concept of a microbiota-associated effect on the neuroactive pathways even in healthy young women. This suggest, that targeting the gut microbiome could be a promising approach for future psychiatric interventions.

    Women's experiences of internet-delivered Cognitive Behaviour Therapy (iCBT) for Fear of Birth2020In: Women and Birth, ISSN 1871-5192, E-ISSN 1878-1799, Vol. 33, no 3, p. E227-E233Article in journal (Refereed)
    Abstract [en]

    Background: Fear of Birth is common in pregnant women and associated with negative physical and mental health. There is a clear comorbidity with anxiety and depression. Internet-delivered Cognitive Behaviour Therapy has been suggested as a treatment option for Fear of Birth and a randomized controlled trial comparing internet-delivered Cognitive Behaviour Therapy with midwifery led counselling as standard care has been conducted.

    Objective: The aim of this study was to describe women's experiences of guided internet-delivered Cognitive Behaviour Therapy for Fear of Birth and to describe the content of their fear.

    Methods: The present study is a qualitative, follow-up interview study following the randomized controlled trial, the U-CARE Pregnancy Trial. In total 19 women allocated to internet-delivered Cognitive Behaviour Therapy for Fear of Birth were interviewed by telephone. A semi-structured interview guide was used and the transcripts were analyzed with thematic analysis.

    Results: The women's descriptions of Fear of Birth differed, however their fear was most often associated with fear of losing control, fear for the baby's life or health or own life threatening events. The experiences of internet-delivered Cognitive Behaviour Therapy for Fear of Birth varied, some women were positive to its flexibility although most women preferred a face-to face meeting. The treatment did not pin-point their fears, it was challenging to maintain motivation and to work with the treatment in solitude.

    Conclusions: Women's descriptions of Fear of Birth varied. Most women undergoing internet-delivered Cognitive Behaviour Therapy would have preferred a face-to-face meeting which they imagined would have soothed their fear. Internet-delivered Cognitive Behaviour Therapy for Fear of Birth may be an alternative for some women.

    Mode of conception in relation to nausea and vomiting of pregnancy: a nested matched cohort study in Sweden2021In: Scientific Reports, E-ISSN 2045-2322, Vol. 11, no 1, article id 9039Article in journal (Refereed)
    Abstract [en]

    Nausea and vomiting of pregnancy (NVP) is a common condition reported however inconclusively among pregnancies after assisted conception. The study objective was thus to explore whether NVP is associated to mode of conception or other in vitro fertilization (IVF)-related variables. This nested matched cohort study, originating from the BASIC-project, was conducted at the Uppsala University Hospital in Sweden between 2010 and 2016. IVF pregnancies (n=210) and age and parity-matched women with spontaneous pregnancies (n=420) comprised the study sample. The study outcome was self-reported NVP at gestational week 17. IVF treatment and pregnancy data were obtained after scrutinization of the medical records. NVP with or without medications was not associated with mode of conception (chi-square test, p=0.889), even after adjusting for potential confounders. In a subgroup analysis among IVF pregnancies, NVP without medication was more frequently seen in the group who received cleavage stage embryos vs blastocysts (chi-square test, p=0.019), exhibiting a marginally significant but strongly increased effect even after adjustment [crude RRR 3.82 (95% CI 1.23-11.92) and adjusted RRR 3.42 (95% CI 0.96-12.11)]. No difference in the rate of NVP with or without medication between women that underwent fresh and frozen/thawed embryo transfers as well as IVF or ICSI was observed. Conception through IVF is not associated with NVP. Transfer of a blastocyst may decrease the risk of developing NVP and further, large-scale prospective studies are required to validate this finding.

    Conception by means of in vitro fertilization (IVF) is not associated with nausea and vomiting of pregnancy2020Conference paper (Refereed)
    Abstract [en]

    Study question:

    Is there any association between mode of conception or IVF-related variables and nausea and vomiting of pregnancy (NVP)?

    Summary answer:

    Conception by means of IVF is not associated with NVP but the stage of the transferred embryo may affect NVP development.

    What is known already:

    The exact cause of NVP is unknown but risk factors including increased hormonal levels, maternal distress and anxiety disorders, also described in IVF populations, have been reported. There are only a few studies exploring NVP in IVF samples. A population-based study examining the characteristics of women who suffered from a severe form of NVP, it was reported that women with severe NVP had more often conceived through assisted reproduction techniques. So far, the relationship between NVP and IVF or different treatment related parameters in the IVF population in relation to NVP remains unclear.

    Study design, size, duration:

    The study is a longitudinal, matched - cohort, pilot study including 630 pregnant women with singletons without malformations, recruited during the pregnancy ultrasound in gestational week 17 (GW 17). The study was conducted between 2010-2016 at the University Hospital of Uppsala, Sweden.

    Participants/materials, setting, methods:

    The study population comprised 210 women with IVF conceived pregnancies and 420 age and parity matched women with spontaneous pregnancies. All participants self-reported sociodemographic and pregnancy-related information. IVF treatment data were obtained after scrutinization of the medical records. The outcome, NVP at GW 17, was divided into: 1) absence of NVP, 2) NVP not requiring medications and 3) NVP requiring medications. NVP was then studied in relation to exposure and to different IVF treatment-associated variables.

    Main results and the role of chance:

    The mean age of the participants was 33.7 years with 2/3 of the participants being primipara. IVF pregnant women reported more frequently comorbidities (such as hypertension, diabetes, migraine etc) (59.1% vs 49.9%), but less frequently alcohol consumption (38.4% vs 48.7%) compared to women with spontaneous pregnancies. Clinical and sociodemographic characteristics such as education, employment, smoking habits, maternal BMI, depression history, delivery fear and newborn gender, were otherwise similar between the groups. NVP with or without medications was not associated with mode of conception (p=0.889); 11.4% of women who conceived through IVF suffered from NVP requiring medications and 62.4% from unmedicated NVP vs 10.8% and 64.3% respectively of women with spontaneous pregnancies. Absence of NVP was reported by 26.2% of IVF and 24.9% of spontaneously pregnant women. However, in a subgroup analysis in the group of women who conceived through IVF, NVP was more frequently seen in the group who received cleavage stage embryos vs blastocysts (p=0.019). We could not however find any significant difference in the rate of NVP with or without medications between fresh (69.4%) or frozen/thawed embryo transfers (78.5%), nor between IVF(72.3%) and intracytoplasmic sperm injection(ICSI)(77.4%) treatments. Lastly, there was no significant difference between infertility diagnosis and NVP.

    Limitations, reasons for caution:

    The study had limited power to detect differences in NVP in relation to mode of conception. In addition, there was a missing rate of 30.5% in the reported embryo stage variable. Finally, the rate of blastocyst-transfers during that period was lower than otherwise expected with current statistics.

    Wider implications of the findings:

    It is still unclear whether IVF has an impact on the risk of NVP. However, transfer of a blastocyst may decrease the risk of developing NVP.
