  • Managing an altered social context-Patients experiences of staying away from home while undergoing proton beam therapy
  • 2020
  • Ingår i: Nursing Open. - : John Wiley & Sons. - 2054-1058. ; 7:4, s. 1157-1163
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To illuminate the experience of an altered social context for patients with primary brain tumours living away from home while undergoing proton beam therapy.Design: A descriptive, qualitative cross-sectional interview study.Methods: Nineteen patients were interviewed between December 2015-August 2016, either during (N = 7) or before and after (N = 12) their proton beam therapy. A hermeneutical analysis was performed.Results: Participants made adjustments to achieve control and well-being during the treatment period. The analysis also revealed two interrelated patterns that helped participants adjust: being part of the family from a distance and seeking affinity.Conclusion: It is important that patients receiving treatment far from home find a way to remain a part of their family and find affinity in the altered social context. Health professionals can prepare patients for the treatment period and can implement interventions to promote well-being for both patients and their relatives.

  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

    • IntroductionPeripartum depression (PPD) impacts around 12% of women globally and is a leading cause of maternal mortality. However, there are currently no accurate methods in use to identify women at high risk for depressive symptoms on an individual level. An initial study was done to assess the value of deep learning models to predict perinatal depression from women at six weeks postpartum. Clinical, demographic, and psychometric questionnaire data was obtained from the “Biology, Affect, Stress, Imaging and Cognition during Pregnancy and the Puerperium” (BASIC) cohort, collected from 2009-2018 in Uppsala, Sweden. An ensemble of artificial neural networks and decision trees-based classifiers with majority voting gave the best and balanced results, with nearly 75% accuracy. Predictive variables identified in this study were used to inform the development of the ongoing Swedish Mom2B study.ObjectivesThe aim of the Mom2be study is to use digital phenotyping data collected via the Mom2B mobile app to evaluate predictive models of the risk of perinatal depression.MethodsIn the Mom2B app, clinical, sociodemographic and psychometric information is collected through questionnaires, including the Edinburgh Postnatal Depression Scale (EPDS). Audio recordings are recurrently obtained upon prompts, and passive data from smartphone sensors and activity logs, reflecting social-media activity and mobility patterns. Subsequently, we will implement and evaluate advanced machine learning and deep learning models to predict the risk of PPD in the third pregnancy trimester, as well as during the early and late postpartum period, and identify variables with the strongest predictive value.ResultsAnalyses are ongoing.ConclusionsPending results.DisclosureNo significant relationships.

  • Predicting perinatal health outcomes using smartphone-based digital phenotyping and machine learning in a prospective Swedish cohort (Mom2B) : study protocol
  • 2022
  • Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 12:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Perinatal complications, such as perinatal depression and preterm birth, are major causes of morbidity and mortality for the mother and the child. Prediction of high risk can allow for early delivery of existing interventions for prevention. This ongoing study aims to use digital phenotyping data from the Mom2B smartphone application to develop models to predict women at high risk for mental and somatic complications.Methods and analysis: All Swedish-speaking women over 18 years, who are either pregnant or within 3 months postpartum are eligible to participate by downloading the Mom2B smartphone app. We aim to recruit at least 5000 participants with completed outcome measures. Throughout the pregnancy and within the first year postpartum, both active and passive data are collected via the app in an effort to establish a participant's digital phenotype. Active data collection consists of surveys related to participant background information, mental and physical health, lifestyle, and social circumstances, as well as voice recordings. Participants' general smartphone activity, geographical movement patterns, social media activity and cognitive patterns can be estimated through passive data collection from smartphone sensors and activity logs. The outcomes will be measured using surveys, such as the Edinburgh Postnatal Depression Scale, and through linkage to national registers, from where information on registered clinical diagnoses and received care, including prescribed medication, can be obtained. Advanced machine learning and deep learning techniques will be applied to these multimodal data in order to develop accurate algorithms for the prediction of perinatal depression and preterm birth. In this way, earlier intervention may be possible.Ethics and dissemination: Ethical approval has been obtained from the Swedish Ethical Review Authority (dnr: 2019/01170, with amendments), and the project fully fulfils the General Data Protection Regulation (GDPR) requirements. All participants provide consent to participate and can withdraw their participation at any time. Results from this project will be disseminated in international peer-reviewed journals and presented in relevant conferences.

  • Biomarkers for Peripartum Depression : Focusing on aspects of the immune system and the metabolome
  • 2021
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Peripartum depression is a common, multifactorial, and potentially devastating disease among new mothers. A biological marker for peripartum depression would facilitate early detection, better understanding of the pathophysiology, and identification of targets for treatment. Evidence is growing for a potential role of the immune system in depression outside the peripartum period. Major adaptations of the immune system occur during pregnancy, justifying the search for immunological markers for peripartum depression. The immune system is very complex and dynamic during pregnancy, complicating the study of associations with depression. The metabolome is also affected by pregnancy and is linked to the immune system via, e.g., the microbiota. Hence, metabolomic profiling could increase the understanding of peripartum depression. This thesis aimed to explore inflammatory markers and metabolic profiles in the peripartum period, in order to discover possible biomarkers, and to increase the understanding of the pathophysiology of peripartum depression.All studies were conducted within the Biology, Affect, Stress, Imaging, and Cognition (BASIC) study. The Edinburgh Postnatal Depression Scale and the Mini International Neuropsychiatric Interview were used to assess depressive symptoms. Multiplex Proximity Extension assays were used to analyze inflammatory markers in pregnancy and postpartum. Luminex Bio-Plex Pro Human Cytokine Assays were used to analyze cytokine levels across the peripartum period, and gas chromatography-mass spectrometry metabolomics were used for metabolic profiling. No marker was discriminative enough to be used on its own as a biomarker for peripartum depression. However, several inflammatory markers (such as STAM-BP, TRANCE, HGF, IL-18, FGF-23, and CXCL1) were identified as possible candidates for more advanced diagnostic algorithms. The results further pointed towards the importance of adaptation of the immune system during pregnancy and postpartum, where levels of cytokines such as VEGF-A might have an important role in antenatal and postpartum depression. The results even highlight the importance of examination timing. Lastly, the metabolic profiling suggested different subgroups of women with postpartum depressive symptoms, supporting theories of peripartum depression being a heterogeneous disease in need of subgroup definition.

  • Inflammatory markers in late pregnancy in association with postpartum depression-A nested case-control study.
  • 2017
  • Ingår i: Psychoneuroendocrinology. - : Elsevier BV. - 0306-4530 .- 1873-3360. ; 79, s. 146-159
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent studies indicate that the immune system adaptation during pregnancy could play a significant role in the pathophysiology of perinatal depression. The aim of this study was to investigate if inflammation markers in a late pregnancy plasma sample can predict the presence of depressive symptoms at eight weeks postpartum. Blood samples from 291 pregnant women (median and IQR for days to delivery, 13 and 7-23days respectively) comprising 63 individuals with postpartum depressive symptoms, as assessed by the Edinburgh postnatal depression scale (EPDS≥12) and/or the Mini International Neuropsychiatric Interview (M.I.N.I.) and 228 controls were analyzed with an inflammation protein panel using multiplex proximity extension assay technology, comprising of 92 inflammation-associated markers. A summary inflammation variable was also calculated. Logistic regression, LASSO and Elastic net analyses were implemented. Forty markers were lower in late pregnancy among women with depressive symptoms postpartum. The difference remained statistically significant for STAM-BP (or otherwise AMSH), AXIN-1, ADA, ST1A1 and IL-10, after Bonferroni correction. The summary inflammation variable was ranked as the second best variable, following personal history of depression, in predicting depressive symptoms postpartum. The protein-level findings for STAM-BP and ST1A1 were validated in relation to methylation status of loci in the respective genes in a different population, using openly available data. This explorative approach revealed differences in late pregnancy levels of inflammation markers between women presenting with depressive symptoms postpartum and controls, previously not described in the literature. Despite the fact that the results do not support the use of a single inflammation marker in late pregnancy for assessing risk of postpartum depression, the use of STAM-BP or the novel notion of a summary inflammation variable developed in this work might be used in combination with other biological markers in the future.

  • Inflammatory markers in women with postpartum depressive symptoms
  • 2020
  • Ingår i: Journal of Neuroscience Research. - : Wiley. - 0360-4012 .- 1097-4547. ; 98:7, s. 1309-1321
  • Tidskriftsartikel (refereegranskat)abstract
    • Postpartum depression (PPD) is a devastating disorder affecting not only more than 10% of all women giving birth, but also the baby, the family, and the society. Compiling evidence suggests the involvement of the immune system in the pathophysiology of major depression; yet, the immune response in perinatal depression is not as well studied. The aim of this study was to investigate the alterations in peripheral levels of inflammatory biomarkers in 169 Swedish women with and without depressive symptoms according to the Edinburgh postnatal depression scale or the M.I.N.I neuropsychiatric interview at eight weeks postpartum. Among the 70 markers analyzed with multiplex proximity extension assay, five were significantly elevated in women with postpartum depressive symptoms in the adjusted LASSO logistic regression analysis: Tumor necrosis factor ligand superfamily member (TRANCE) (OR-per 1 SD increase = 1.20), Hepatocyte growth factor (HGF) (OR = 1.17) Interleukin (IL)-18 (OR = 1.06), Fibroblast growth factor 23 (FGF-23) (OR = 1.25), and C-X-C motif chemokine 1 (CXCL1) (OR 1.11). These results indicate that women with PPD have elevated levels of some inflammatory biomarkers. It is, therefore, plausible that PPD is associated with a compromised adaptability of the immune system.

  • Longitudinal assessment of inflammatory markers in the peripartum period by depressive symptom trajectory groups
  • 2022
  • Ingår i: Brain, Behavior, & Immunity - Health. - : Elsevier. - 2666-3546. ; 22
  • Tidskriftsartikel (refereegranskat)abstract
    • ObjectiveMechanisms driving temporal fluctuations of inflammatory markers during pregnancy, and how these might differ between distinct perinatal depressive trajectories, are not well understood. The aim of this study was to investigate cytokines levels over the course of pregnancy in women with different trajectories of depressive symptoms peripartum, and relate the levels to levels of non-pregnant controls.MethodsBased on the Edinburgh Postnatal Depression Scale and/or selective serotonin reuptake inhibitors use, 131 women were categorized into: no (n = 65); antepartum (APD, n = 19), postpartum (PPD, n = 17) and persistent (n = 30) depressive symptoms. Plasma samples (n = 386) were analyzed for levels of interleukin (IL)-8, IL-18, Tumor necrosis factor-α, macrophage colony-stimulating factor (M-CSF), vascular endothelial growth factor A (VEGF-A) and fractalkine, at four different time-points (twice during pregnancy, during childbirth, and postpartum) using Bio-Plex Pro Human Cytokine Assays. Generalized linear mixed models were applied to analyze the associations between cytokine levels, time-point, perinatal depressive symptom trajectory group and their interaction.ResultsFor all markers but VEGF-A, pregnancy was associated with higher cytokine levels compared to the non-pregnant controls, with delivery being the most prominent time-point. For M-CSF, IL-18 and VEGF-A, levels were back to the non-pregnant status at postpartum week 8. An effect of perinatal depressive symptom trajectory groups on cytokine levels was found for VEGF-A. Women with PPD and women with APD had lower levels of VEGF-A throughout the study period compared to women with persistent depression, and women with PPD had lower levels compared to non-depressed women.ConclusionsLower levels of VEGF-A were noted among women in some trajectories of depressive symptoms peripartum. The peripartum period is a time of tremendous immune system adaptations. Standardization of time-points for cytokine measurements in studies of perinatal depression are important in order to draw valid conclusions on the role of the immune system in perinatal depression.

  • Metabolic Profiling Indicates Diversity in the Metabolic Physiologies Associated With Maternal Postpartum Depressive Symptoms
  • 2021
  • Ingår i: Frontiers in Psychiatry. - : Frontiers Media S.A.. - 1664-0640. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Postpartum depression (PPD) is a devastating disease requiring improvements in diagnosis and prevention. Blood metabolomics identifies biological markers discriminatory between women with and those without antenatal depressive symptoms. Whether this cutting-edge method can be applied to postpartum depressive symptoms merits further investigation. Methods: As a substudy within the Biology, Affect, Stress, Imagine and Cognition Study, 24 women with PPD symptom (PPDS) assessment at 6 weeks postpartum were included. Controls were selected as having a score of ≤ 6 and PPDS cases as ≥12 on the Edinburgh Postnatal Depression Scale. Blood plasma was collected at 10 weeks postpartum and analyzed with gas chromatography-mass spectrometry metabolomics. Results: Variations of metabolomic profiles within the PPDS samples were identified. One cluster showed altered kidney function, whereas the other, a metabolic syndrome profile, both previously associated with depression. Five metabolites (glycerol, threonine, 2-hydroxybutanoic acid, erythritol, and phenylalanine) showed higher abundance among women with PPDSs, indicating perturbations in the serine/threonine and glycerol lipid metabolism, suggesting oxidative stress conditions. Conclusions: Alterations in certain metabolites were associated with depressive pathophysiology postpartum, whereas diversity in PPDS physiologies was revealed. Hence, plasma metabolic profiling could be considered in diagnosis and pathophysiological investigation of PPD toward providing clues for treatment. Future studies require standardization of various subgroups with respect to symptom onset, lifestyle, and comorbidities.

  • Who do we miss when screening for postpartum depression? : A population-based study in a Swedish region
  • 2021
  • Ingår i: Journal of Affective Disorders. - : Elsevier. - 0165-0327 .- 1573-2517. ; 287, s. 165-173

    • BackgroundUniversal screening for postpartum depression is crucial for early detection, interventions and support. The aim of this study was to describe the proportion of, and explore risk factors for, women not being offered screening, as well as for declining an offer or not being screened due to any other unknown reason.MethodsSocioeconomic, obstetrical and neonatal data, extracted from the Swedish Pregnancy Registry, for 9,959 pregnancies recorded for the Östergötland county between 2016 and 2018 were linked to Edinburgh Postnatal Depression Scale (EPDS) screening results at 6–8 weeks postpartum, extracted from medical records. Risk factors were assessed using logistic regression models and with a nomogram for easy visualization.ResultsIn total, there were no recorded offers of EPDS screening in the medical records for 30.0% of women at the postpartum follow-up. Women born outside of Sweden and women reporting poor self-rated health were at increased risk of not being offered screening for postpartum depression.LimitationsThere is a possibility that women were offered screening or were screened, but this was incorrectly or never recorded in medical records.ConclusionsThe majority of women were offered screening for postpartum depression, but there is room for improvement in order to achieve universal screening. Awareness among healthcare providers of the risk factors for not screening might increase adherence to guidelines for universal screening. Overcoming barriers for screening and raising the topic of mental-health issues for postpartum women should be prioritized.

  • Differentiated mental health patterns in pregnancy during COVID-19 first two waves in Sweden : a mixed methods study using digital phenotyping
  • 2022
  • Ingår i: Scientific Reports. - : Springer Nature. - 2045-2322. ; 12:1
  • Tidskriftsartikel (refereegranskat)abstract
    • To utilize modern tools to assess depressive and anxiety symptoms, wellbeing and life conditions in pregnant women during the first two waves of the COVID-19 pandemic in Sweden. Pregnant women (n = 1577) were recruited through the mobile application Mom2B. Symptoms of depression, anxiety and wellbeing were assessed during January 2020–February 2021. Movement data was collected using the phone’s sensor. Data on Google search volumes for “Corona” and Covid-related deaths were obtained. Qualitative analysis of free text responses regarding maternity care was performed. Two peaks were seen for depressive symptoms, corresponding to the two waves. Higher prevalence of anxiety was only noted during the first wave. A moderating effect of the two waves in the association of depression, anxiety, and well-being with Covid deaths was noted; positive associations during the first wave and attenuated or became negative during the second wave. Throughout, women reported on cancelled healthcare appointments and worry about partners not being allowed in hospital. The association of mental health outcomes with relevant covariates may vary during the different phases in a pandemic, possibly due to adaptation strategies on a personal and societal/healthcare level. Digital phenotyping can help healthcare providers and governmental bodies to in real time monitor high-risk groups during crises, and to adjust the support offered.

  • Increased risk of mental health problems after cancer during adolescence : a register based cohort study.
  • 2020
  • Ingår i: International Journal of Cancer. - : Wiley. - 0020-7136 .- 1097-0215. ; 147:12, s. 3349-3360
  • Tidskriftsartikel (refereegranskat)abstract
    • In this nationwide, register-based study, we estimated the risk of mental health problems in 2,822 individuals diagnosed with cancer in adolescence (13-19 years). Mental health problems were assessed by psychiatric diagnoses and/or prescribed psychotropic drugs. Cox proportional hazards models estimated hazard ratio (HR) for a psychiatric diagnosis and prescription of psychotropic drug compared to a matched comparison group (n=28,220). Estimates were adjusted for calendar period and parent characteristics (e.g., history of psychiatric diagnosis, education, country of birth). We found an increased risk of a psychiatric diagnosis during the first five years after the cancer diagnosis (females: HR 1.23, 95% CI, 1.06-1.44; males: HR 1.32, 95% CI, 1.11-1.56), and at >five years after diagnosis (females: HR 1.31, 95% CI, 1.09-1.58, males: HR 1.45, 95% CI, 1.18-1.77). The risk of being prescribed antidepressant- (females: HR 1.54, 95% CI, 1.30-1.84, males: HR 2.06, 95% CI, 1.66-2.55), antipsychotic- (females: HR 2.28, 95% CI, 1.56-3.34, males: HR 3.07, 95% CI, 2.13-4.42), anxiolytic- (females: HR 1.95, 95% CI, 1.64-2.31, males: HR 4.02, 95% CI, 3.34-4.84), and sedative drugs (females: HR 2.24, 95% CI, 1.84-2.72, males: HR 3.91, 95% CI, 3.23-4.73) were higher than for comparisons during the first five years after diagnosis. Median age at first psychiatric diagnosis and first prescribed psychotropic drug was 18 years. In conclusion, cancer during adolescence is associated with increased risk of mental health problems that may develop in close proximity to treatment. The findings emphasize the need for comprehensive care during treatment and follow-up.

  • Heart rate variability in late pregnancy : exploration of distinctive patterns in relation to maternal mental health
  • 2021
  • Ingår i: Translational Psychiatry. - : Springer Nature. - 2158-3188. ; 11
  • Tidskriftsartikel (refereegranskat)abstract
    • Exploration of photoplethysmography (PPG), a technique that can be translated to the clinic, has the potential to assess the autonomic nervous system (ANS) through heart rate variable (HRV) in pregnant individuals. This novel study explores the complexity of mental health of individuals in a clinical sample responding to a task in late pregnancy; finding those with several types of past or current anxiety disorders, greater trait anxiety, or greater exposure to childhood traumatic events had significantly different HRV findings from the others in the cohort. Lower high frequency (HF), a measure of parasympathetic activity, was found for women who met the criteria for the history of obsessive-compulsive disorder (OCD) (p = 0.004) compared with women who did not meet the criteria for OCD, and for women exposed to greater than five childhood traumatic events (p = 0.006) compared with those exposed to four or less childhood traumatic events. Conversely higher low frequency (LF), a measure thought to be impacted by sympathetic system effects, and the LF/HF ratio was found for those meeting criteria for a panic disorder (p = 0.006), meeting criteria for social phobia (p = 0.002), had elevated trait anxiety (p = 0.006), or exposure to greater than five childhood traumatic events (p = 0.004). This study indicates further research is needed to understand the role of PPG and in assessing ANS functioning in late pregnancy. Study of the impact of lower parasympathetic functioning and higher sympathetic functioning separately and in conjunction at baseline and in relation to tasks during late pregnancy has the potential to identify individuals that require more support and direct intervention.

  • DNA methylation in cord blood in association with prenatal depressive symptoms
  • 2021
  • Ingår i: Clinical Epigenetics. - : BioMed Central (BMC). - 1868-7083 .- 1868-7075. ; 13:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Prenatal symptoms of depression (PND) and anxiety affect up to every third pregnancy. Children of mothers with mental health problems are at higher risk of developmental problems, possibly through epigenetic mechanisms together with other factors such as genetic and environmental. We investigated DNA methylation in cord blood in relation to PND, taking into consideration a history of depression, co-morbidity with anxiety and selective serotonin reuptake inhibitors (SSRI) use, and stratified by sex of the child. Mothers (N = 373) prospectively filled out web-based questionnaires regarding mood symptoms and SSRI use throughout pregnancy. Cord blood was collected at birth and DNA methylation was measured using Illumina MethylationEPIC array at 850 000 CpG sites throughout the genome. Differentially methylated regions were identified using Kruskal-Wallis test, and Benjamini-Hochberg adjusted p-values < 0.05 were considered significant.Results: No differential DNA methylation was associated with PND alone; however, differential DNA methylation was observed in children exposed to comorbid PND with anxiety symptoms compared with healthy controls in ABCF1 (log twofold change - 0.2), but not after stratification by sex of the child. DNA methylation in children exposed to PND without SSRI treatment and healthy controls both differed in comparison with SSRI exposed children at several sites and regions, among which hypomethylation was observed in CpGs in the promoter region of CRBN (log2 fold change - 0.57), involved in brain development, and hypermethylation in MDFIC (log2 fold change 0.45), associated with the glucocorticoid stress response.Conclusion: Although it is not possible to assess if these methylation differences are due to SSRI treatment itself or to more severe depression, our findings add on to existing knowledge that there might be different biological consequences for the child depending on whether maternal PND was treated with SSRIs or not.

  • Tidskriftsartikel (refereegranskat)abstract
    • Children of mothers with prenatal depressive symptoms (PND) have a higher risk of behavioral problems; fetal programming through DNA methylation is a possible underlying mechanism. This study investigated DNA methylation in cord blood to identify possible "at birth" signatures that may indicate susceptibility to behavioral problems at 18 months of age. Cord blood was collected from 256 children of mothers who had self-reported on symptoms of depression during pregnancy and the behavior of their child at 18 months of age. Whole genome DNA methylation was assessed using Illumina MethylationEPIC assay. The mother and child pairs were categorized into four groups, based on both self-reported depressive symptoms, PND or Healthy control (HC), and scores from the Child Behavior checklist (high or low for internalizing, externalizing, and total scores). Adjustments were made for batch effects, cell-type, and clinical covariates. Differentially methylated sites were identified using Kruskal-Wallis test, and Benjamini-Hochberg adjusted p values < 0.05 were considered significant. The analysis was also stratified by sex of the child. Among boys, we observed higher and correlated DNA methylation of one CpG-site in the promoter region of TPP1 in the HC group, with high externalizing scores compared to HC with low externalizing scores. Boys in the PND group showed lower DNA methylation in NUDT15 among those with high, compared to low, internalizing scores; the DNA methylation levels of CpGs in this gene were positively correlated with the CBCL scores. Hence, the differentially methylated CpG sites could be of interest for resilience, regardless of maternal mental health during pregnancy. The findings are in a relatively healthy study cohort, thus limiting the possibility of detecting strong effects associated with behavioral difficulties. This is the first investigation of cord blood DNA methylation signs of fetal programming of PND on child behavior at 18 months of age and thus calls for independent replications.

  • Working Memory During Late Pregnancy : Associations With Antepartum and Postpartum Depression Symptoms
  • 2022
  • Ingår i: Frontiers in Global Women's Health. - : Frontiers Media S.A.. - 2673-5059. ; 3
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundFew studies, with conflicting results, report on the association between memory performance and depressive symptoms during the perinatal period. In this study, we aimed to evaluate whether memory performance during late pregnancy is associated with antepartum (APD) and postpartum depression (PPD) symptoms.MethodWe conducted a prospective follow-up of 283 pregnant women, nested within a large cohort of women enrolled in the BASIC study in Uppsala University hospital between 2009 and 2019. The Wechsler Digit Span Task (forward-DSF, backward-DSB and total score-DST) was performed to evaluate short-term memory/attention (DSF) and working memory (DSB) around the 38th gestational week; the Edinburgh Postnatal Depression Scale (EPDS), evaluating depressive symptoms, was filled out at 17, 32, 38 gestational weeks, as well as at 6 weeks postpartum. Unadjusted and multivariate logistic regression was used to assess the association between performance on the Digit Span Task and outcome, namely depressive symptoms (using a cut-off of 12 points on the EPDS) at 38 gestational weeks, as well as at 6 weeks postpartum.ResultsAPD symptoms were not significantly associated with DSF (p = 0.769) or DSB (p = 0.360). APD symptoms were significantly associated with PPD symptoms (p < 0.001). Unadjusted regression modeling showed that DSF in pregnancy was a significant predictor of PPD symptoms (OR 1.15; 95% CI, 1.00, 1.33, p = 0.049), and remained a significant predictor when adjusted for confounders (education and feeling rested at assessment; OR 1.21, 95% CI 1.03, 1.42, p = 0.022). DSF was a predictor of PPD symptoms only for women without a pre-pregnancy history of depression (OR 1.32; 95% CI 1.04, 1.67, p = 0.024) and also those without APD (OR 1.20, 95% CI 1.01, 1.43, p = 0.040).ConclusionThere was no significant association between working and short-term memory performance and APD symptoms. Among all women, but especially non-depressed earlier in life and/or at antepartum, those scoring high on the forward memory test, i.e., short-term memory, had a higher risk for PPD. Future studies are required to further explore the pathophysiology behind and the predictive value of these associations.

  • Evaluation of skin reactions during proton beam radiotherapy : patient-reported versus clinician-reporte
  • 2021
  • Ingår i: Technical innovations & patient support in radiation oncology. - : Elsevier. - 2405-6324. ; 19, s. 11-17
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Skin reaction is a common side-effect of radiotherapy and often only assessed as clinician-reported outcome (CRO). The aim was to examine and compare patient-reported outcome (PRO) of skin reactions with CRO for signs of acute skin reactions for patients with primary brain tumour receiving proton beam radiotherapy (PBT). A further aim was to explore patients' experiences of the skin reactions.Methods: Acute skin reactions were assessed one week after start of treatment, mid-treatment and end of treatment among 253 patients with primary brain tumour who underwent PBT. PRO skin reactions were assessed with the RSAS and CRO according to the RTOG scale. Fleiss' kappa was performed to measure the inter-rater agreement of the assessments of skin reactions.Results: The results showed a discrepancy between PRO and CRO acute skin reactions. Radiation dose was associated with increased skin reactions, but no correlations were seen for age, gender, education, occupation, other treatment or smoking. There was a poor agreement between patients and clinicians (κ = -0.016) one week after the start of PBT, poor (κ = -0.045) to (κ = 0.396) moderate agreement at mid treatment and poor (κ = -0.010) to (κ = 0.296) moderate agreement at end of treatment. Generally, patients' symptom distress toward skin reactions was low at all time points.Conclusion: The poor agreement between PRO and CRO shows that the patient needs to be involved in assessments of skin reactions for a more complete understanding of skin reactions due to PBT. This may also improve patient experience regarding involvement in their own care.

  • Psychotropic medication use in parents of survivors of adolescent cancer : A register-based cohort study
  • 2022
  • Ingår i: Cancer Medicine. - : Wiley. - 2045-7634. ; 11:22, s. 4341-4353
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The aim was to investigate psychotropic medication use in parents of survivors of adolescent cancer from the acute post-diagnostic phase and up to 2 years following the cancer diagnosis.METHODS: This study had a nationwide register-based cohort design comparing psychotropic medication use in parents of adolescent survivors of cancer (n = 2323) to use in parents of cancer-free controls (n = 20,868). Cox proportional hazards models, adjusted for cancer diagnostic group, parents' age, country of birth, education level, marital status and previous mental health problems estimated the risk of use from the time of the cancer diagnosis up to 2 years later.RESULTS: During the first 6 months after the cancer diagnosis, both mothers and fathers had an increased risk of use of anxiolytics (mothers: HRadj 1.71, 95% CI 1.30-2.25; fathers: HRadj 1.57, 95% CI 1.10-2.45) and hypnotics/sedatives (mothers: HRadj 1.53, 95% CI 1.23-1.90; fathers: HRadj 1.32, 95% CI 1.00-1.75). For fathers with a prescription of psychotropic medication during the first 6 months after the cancer diagnosis, the risk remained increased after 6 months (HRadj 1.66, 95% CI 1.04-2.65). From 6 months after the cancer diagnosis, only the risk of antidepressant use among mothers was increased (HRadj 1.38, 95% CI 1.08-1.76). Risk factors included being divorced/widowed, born in a non-Nordic country, older age and having had previous mental health problems.CONCLUSION: Our study results show that during the immediate post-diagnostic phase, mothers and fathers of survivors of adolescent cancer are at increased risk of use of anxiolytics and sedatives, whereas only mothers are at increased risk of antidepressant use from 6 months until 2 years after the diagnosis. Further, previous mental health problems were shown to be the strongest risk factor for psychotropic medication use in both mothers and fathers, pointing to the particular vulnerability of these parents.

  • Free choice of treatment content, support on demand and supervision in internet-delivered CBT for adults with depression : A randomized factorial design trial

  • Tidskriftsartikel (refereegranskat)abstract
    • Even if much is known regarding the effects of internet-delivered cognitive behaviour therapy (ICBT) for depression there are several topics that have not been studied. In this factorial design trial with 197 participants we investigated if clients in ICBT could select treatment modules themselves based on a selection of 15 tailored treatment modules developed for use in ICBT for depression. We contrasted this against clinician-tailored module selection. We also investigated if support on demand (initiated by the client) could work as well as scheduled support. Finally, we tested if clients that were mentioned in supervision would improve more than clients not mentioned (with the exception of acute cases). The treatment period lasted for 10 weeks, and we measured effects at post-treatment and two-year follow-up. Measures of depression and secondary outcomes were collected at pre-treatment, post-treatment and two-year follow-up. Overall, within-group effects were large across con-ditions (e.g., d = 1.73 on the BDI-II). We also found a small but significant difference in favour of self-tailored treatment over clinician-tailored (d = 0.26). Within-group effects for the secondary measures were all moderate to large including a test of knowledge about CBT. The other two contrasts "support on demand" and "supervision" yielded mostly non-significant differences, with the exception of a larger dropout rate in the support on demand condition. There were few negative effects (2.2%). Effects were largely maintained at a two-year follow-up. We conclude that clients can choose treatment modules and that support on demand may work. The role of su-pervision is not yet clear as advice can be transferred across clients.

  • Severe obstetric lacerations associated with postpartum depression among women with low resilience : a Swedish birth cohort study
  • 2020
  • Ingår i: British Journal of Obstetrics and Gynecology. - : Wiley. - 1470-0328 .- 1471-0528. ; 127:11, s. 1382-1390

    • 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.

  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: Joint physical custody, children spending equal time in each parents' respective home after a parental divorce, is particularly common in Nordic compared with other Western countries. Older children have been shown to fare well in this practice but for young children there are few existing studies. The aim of this paper is to study psychological problems in 2- to 9-year-old Nordic children in different family forms. Methods: Total symptom score according to the Strengths and Difficulties Questionnaire as well as scores showing externalizing problems were compared among 152 children in joint physical custody, 303 in single care and 3207 in nuclear families through multiple linear regression analyses. Results: Children in single care had more psychological symptoms than those in joint physical custody (B = 1.08; 95% CI 0.48 to 1.67) and those in nuclear families had the least reported symptoms (B = -0.53; 95% CI -0.89 to -0.17). Externalizing problems were also lower in nuclear families (B = -0.28, 95% CI -0.52 to -0.04) compared with joint physical custody after adjusting for covariates. Conclusions: Young children with non-cohabiting parents suffered from more psychological problems than those in intact families. Children in joint physical custody had a lower total problem score than those in single care after adjusting for covariates. Longitudinal studies with information on family factors before the separation are needed to inform policy of young children's post-separation living arrangements.

    • Background In many Western countries, an increasing number of children with separated parents have joint physical custody, that is, live equally much in their parents respective homes. In Sweden, joint physical custody is particularly common and concerns between 30% and 40% of the children with separated parents. It has been hypothesised that the frequent moves and lack of stability in parenting may be stressful for these children. Methods We used data from a national classroom survey of all sixth and ninth grade students in Sweden (N=147839) to investigate the association between childrens psychosomatic problems and living arrangements. Children in joint physical custody were compared with those living only or mostly with one parent and in nuclear families. We conducted sex-specific linear regression analyses for z-transformed sum scores of psychosomatic problems and adjusted for age, country of origin as well as childrens satisfaction with material resources and relationships to parents. Clustering by school was accounted for by using a two-level random intercept model. Results Children in joint physical custody suffered from less psychosomatic problems than those living mostly or only with one parent but reported more symptoms than those in nuclear families. Satisfaction with their material resources and parent-child relationships was associated with childrens psychosomatic health but could not explain the differences between children in the different living arrangements. Conclusions Children with non-cohabitant parents experience more psychosomatic problems than those in nuclear families. Those in joint physical custody do however report better psychosomatic health than children living mostly or only with one parent. Longitudinal studies with information on family factors before and after the separation are needed to inform policy of childrens postseparation living arrangements.

  • Importance of living arrangements and coparenting quality for young children's mental health after parental divorce : a cross-sectional parental survey

  • Tidskriftsartikel (refereegranskat)abstract
    • Background Parental separation has been associated with adverse child mental health outcomes in the literature. For school-aged children, joint physical custody (JPC), that is, spending equal time in both parents’ homes after a divorce, has been associated with better health and well-being than single care arrangements. Preschool children’s well-being in JPC is less studied. The aim of this study was to investigate the association of living arrangements and coparenting quality with mental health in preschool children after parental separation.Methods This cross-sectional population-based study includes 12 845 three-year-old children in Sweden. Mental health was measured by parental reports of the Strength and Difficulties Questionnaire and coparenting quality with a four-item scale. The living arrangements of the 642 children in non-intact families were categorised into JPC, living mostly with one parent and living only with one parent.Results Linear regression models, adjusted for sociodemographic confounders, showed an association between increased mental health problems and living mostly and only with one parent (B=1.18; 95% CI 0.37 to 2.00, and B=1.20; 95% CI 0.40 to 2.00, respectively), while children in intact families vs JPC did not differ significantly (B=−0.11; 95% CI −0.58 to 0.36). After adjusting the analyses for coparenting quality, differences in child mental health between the post divorce living arrangements were, however, minimal while children in intact families had more mental health problems compared with JPC (B=0.70; 95% CI 0.24 to 1.15). Factorial analysis of covariance revealed that low coparenting quality was more strongly related to mental health problems for children in intact families and JPC compared with children living mostly or only with one parent.Conclusions This study suggests that coparenting quality is a key determinant of mental health in preschool children and thus should be targeted in preventive interventions.

  • Living in two homes-a Swedish national survey of wellbeing in 12 and 15 year olds with joint physical custody
  • 2013
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The practice of joint physical custody, where children spend equal time in each parent's home after they separate, is increasing in many countries. It is particularly common in Sweden, where this custody arrangement applies to 30 per cent of children with separated parents. The aim of this study was to examine children's health-related quality of life after parental separation, by comparing children living with both parents in nuclear families to those living in joint physical custody and other forms of domestic arrangements.Methods Data from a national Swedish classroom study of 164,580 children aged 12 and 15-years-old were analysed by two-level linear regression modelling. Z-scores were used to equalise scales for ten dimensions of wellbeing from the KIDSCREEN-52 and the KIDSCREEN-10 Index and analysed for children in joint physical custody in comparison with children living in nuclear families and mostly or only with one parent.Results Living in a nuclear family was positively associated with almost all aspects of wellbeing in comparison to children with separated parents. Children in joint physical custody experienced more positive outcomes, in terms of subjective wellbeing, family life and peer relations, than children living mostly or only with one parent. For the 12-year-olds, beta coefficients for moods and emotions ranged from -0.20 to -0.33 and peer relations from -0.11 to -0.20 for children in joint physical custody and living mostly or only with one parent. The corresponding estimates for the 15-year-olds varied from -0.08 to -0.28 and from -0.03 to -0.13 on these subscales. The 15-year-olds in joint physical custody were more likely than the 12-year-olds to report similar wellbeing levels on most outcomes to the children in nuclear families.Conclusions Children who spent equal time living with both parents after a separation reported better wellbeing than children in predominantly single parent care. This was particularly true for the 15-year-olds, while the reported wellbeing of 12-years-olds was less satisfactory. There is a need for further studies that can account for the pre and post separation context of individual families and the wellbeing of younger age groups in joint physical custody.

    • This study compared the psychological symptoms of 129 children in joint physical custody with children in single care and nuclear families, using a nationally representative 2011 survey of 1,297 Swedish children aged between four and 18 years. The outcome measure was the Strengths and Difficulties Questionnaire (SDQ) and its association with three dimensions of parental life satisfaction was investigated. Linear regression analyses showed higher SDQ-scores for children in joint physical custody (B=1.4, p<0.001) and single care (B=2.2, p<0.001) than in nuclear families, after adjustment for socio-demographic variables. The estimates decreased to 1.1 and 1.3, respectively, after being adjusted for parental life satisfaction (p<0.01). Our findings confirm previous research that showed lower symptom scores for children in nuclear families than children in single care and joint physical custody. Parental life satisfaction should be investigated further as a possible explanation of differences in symptom load between children in different living arrangements.

    • AIM: Joint physical custody (JPC), where children spend about equal time in both parent's homes after parental separation, is increasing. The suitability of this practice for preschool children, with a need for predictability and continuity, has been questioned.METHODS: In this cross-sectional study, we used data on 3656 Swedish children aged three to five years living in intact families, JPC, mostly with one parent or single care. Linear regression analyses were conducted with the Strengths and Difficulties Questionnaire, completed by parents and preschool teachers, as the outcome measure.RESULTS: Children in JPC showed less psychological problems than those living mostly (adjusted B 1.81; 95% CI [0.66 to 2.95]) or only with one parent (adjusted B 1.94; 95% CI [0.75 to 3.13]), in parental reports. In preschool teacher reports, the adjusted Betas were 1.27, 95% CI [0.14 to 2.40] and 1.41, 95% CI [0.24 to 2.58], respectively. In parental reports, children in JPC and those in intact families had similar outcomes, while teachers reported lower unadjusted symptom scores for children in intact families.CONCLUSION: Joint physical custody arrangements were not associated with more psychological symptoms in children aged 3-5, but longitudinal studies are needed to account for potential preseparation differences.

  • Tidskriftsartikel (refereegranskat)abstract
    • Joint physical custody (JPC) refers to a practice where children with separated parents share their time between the parents' respective homes. Studies on parents' views of JPC for young children are scarce. The aim of this interview study was to explore parents' perceptions on how they experience and practice equally shared JPC for their 1-4 year-olds in Sweden. Forty-six parents (18 fathers and 28 mothers) of 50 children (31 boys and 19 girls) under 5 years of age were interviewed. Parents were recruited through information in the media and represented a broad range of socioeconomic backgrounds, as well as both voluntary and court-ordered custody arrangements. The interviews were semi-structured and analyzed using systematic text condensation. Two themes emerged regarding the research question. In the first theme, Always free, never free, parents described their striving to coparent without a love relationship. While they appreciated the freedom of being a half-time parent, doing things one's own way, they felt constrained by the long-term commitment to live close to and keep discussing child rearing issues with the ex-partner. Good communication was key and lessened parent's feelings of being cut-off from half of the child's life. When JPC was ordered by court or conflicts were intense, parents tried to have less contact and worried when the children were in the other home. The second theme, Is it right, is it good?, included descriptions of how the parents monitored the child's responses to the living arrangement and made changes to optimize their adjustment. Adaptations included visits for the child with the other parent mid-week, shared meals or adapting schedules. In conclusion, these parents worked hard to make JPC work and cause minimal damage to their children. Most parents were pleased with the arrangements with the notable exception of couples experiencing ongoing conflict.

    • Objective Diabetes is frequently linked with depression, and both conditions are common complications during pregnancy. However, research findings exploring the relationship between diabetes mellitus in pregnancy (DMP) and perinatal depression (PND) have been inconsistent. Thus, this study seeks to examine the association between DMP and PND in a prospective population-based cohort.Methods Women aged 18 to 48 years (n = 4459) were identified from the Biology, Affect, Stress, Imaging and Cognition study. The diagnosis of DMP was based on International Classification of Diseases code O24 from medical records and was classified as pregestational, gestational, or unspecified diabetes. PND was assessed using psychometric instruments, clinical interviews, and/or register data and categorized into antepartum or postpartum depression. Multivariable logistic regressions were used to study the associations of DMP with antepartum and postpartum depression. The association between DMP and continuous depression scores, antepartum and postpartum, was investigated with multivariable linear regressions.Results Of 4459 pregnancies, 949 women had antepartum depression (21.2%) and 1123 had postpartum depression (25%). DMP had a prevalence of 1.2%. Women with DMP had twofold higher odds for postpartum depression compared with women without DMP. Although no association was observed between DMP and antepartum depression, DMP was associated with higher antepartum depression scores.Conclusions Our study shows an association between DMP and PND, which might be considered a risk factor when screening for high-risk groups.

    • Perinatal depression is a major cause of disability for individuals giving birth worldwide, with detrimental effects on short- and long-term parental and child outcomes. There is emerging evidence that the neuroactive steroid hormone allopregnanolone is implicated in the pathophysiology and course of perinatal mood symptoms. However, no study thus far has examined allopregnanolone levels whilst making use of longitudinal data on depressive symptom trajectories throughout the perinatal period. The present study investigated levels of allopregnanolone at gestational week 17 of 252 participants in relation to perinatal depressive symptom trajectories, with a secondary aim of exploring the role of history of depression as an effect modifier. Four perinatal depressive symptom trajectories were investigated: controls (no depressive symptoms throughout perinatal period) (N=161), antepartum (depressive symptoms prenatally with postpartum remission) (N=31), postpartumonset (no depressive symptoms during pregnancy, development of depressive symptoms postpartum) (N=23), and persistent (depressive symptoms throughout the perinatal period) (N=37). Results show that for every one nmol/l increase in allopregnanolone, there was 7% higher odds for persistent depressive symptoms (OR 1.07, 95% CI 1.01-1.14) compared to controls. No association was seen for antepartum and postpartum-onset depressive symptoms. History of depression did not modify the association between allopregnanolone and perinatal depressive symptom trajectories. These results show the role of allopregnanolone for persistent depressive symptoms and strengthen the hypothesis of differences in pathophysiology among the trajectories.

    • Physiological hormonal fluctuations exert endogenous pressures on the structure and function of the human microbiome. As such, the menstrual cycle may selectively disrupt the homeostasis of the resident oral microbiome, thus compromising oral health. Hence, the aim of the present study was to structurally and functionally profile the salivary microbiome of 103 women in reproductive age with regular menstrual cycle, while evaluating the modifying influences of hormonal contraceptives, sex hormones, diet, and smoking. Whole saliva was sampled during the menstrual, follicular, and luteal phases (n = 309) of the cycle, and the participants reported questionnaire-based data concerning their life habits and oral or systemic health. No significant differences in alpha-diversity or phase-specific clustering of the overall microbiome were observed. Nevertheless, the salivary abundances of genera Campylobacter, Haemophilus, Prevotella, and Oribacterium varied throughout the cycle, and a higher species-richness was observed during the luteal phase. While the overall community structure maintained relatively intact, its functional properties were drastically affected. In particular, 11 functional modules were differentially abundant throughout the menstrual cycle, including pentose phosphate metabolism, and biosynthesis of cobalamin and neurotransmitter gamma-aminobutyric acid. The menstrual cycle phase, but not oral contraceptive usage, was accountable for greater variations in the metabolic pathways of the salivary microbiome. Further co-risk factor analysis demonstrated that Prevotella and Veillonella were increased in current smokers, whereas high dietary sugar consumption modified the richness and diversity of the microbiome during the cycle. This is the first large study to systematically address dysbiotic variations of the oral microbiome during the course of menstrual cycle, and document the additive effect of smoking and sugar consumption as environmental risk factors. It reveals the structural resilience and functional adaptability of the oral microbiome to the endogenous hormonal pressures of the menstrual cycle, while revealing its vulnerability to the exogenous exposures of diet and smoking.

    • AimThe aim of this study was to assess whether sociodemographic household characteristics were associated with which Swedish adolescents were more likely to be bullied.MethodsThe data were derived from the Swedish Living Conditions Survey and its child supplements from the survey years 2008-2011. The analyses included information on 3,951 adolescents aged 10-18 years. Exposure to bullying was reported by adolescents and information on sociodemographic household characteristics was reported by parents and obtained from official registers. Binary logistic regression was used to analyse the data.ResultsAdolescents were more likely to be bullied if they lived in households with no cash margin, defined as the ability to pay an unexpected bill of 8,000 Swedish Kronor or about 800 Euros, and if they lived with just one custodial parent. In the unadjusted analyses, elevated risks were identified if adolescents lived in working class households and had unemployed and foreign-born parents. However, these associations were at least partly accounted for by other sociodemographic household characteristics, in particular the lack of a cash margin.ConclusionThis study showed that Swedish adolescents living in households with more limited financial resources had an increased risk of being bullied, supporting results from previous international research.

    • BackgroundEarlier research suggests that socioeconomic inequalities in health-related behaviours exist among young people, but with less clearcut patterns than among adults. The aim of the study is to examine to what extent sociodemographic inequalities in health behaviours in terms of alcohol use, smoking, physical inactivity, and regularly skipping breakfast and lunch, exist among adolescents in Sweden.MethodsThe data were obtained from the Swedish Living Conditions Survey (ULF) and its child supplements (Child-ULF) from 2008-2011 (n = 4001). Health-related behaviours were reported by adolescents aged 10-18 years and information on sociodemographic characteristics was derived from parents and from official registers. Binary logistic regression analyses were conducted.ResultsClear sociodemographic inequalities in health-related behaviours were shown. Compared with their peers with parents in upper non-manual occupations, adolescents in working-class households were more likely to smoke (OR 1.53, p = 0.033), to be physically inactive (OR 1.54, p = 0.004), and to regularly skip breakfast (OR 1.78, p = 0.000) and lunch (OR 1.42, p = 0.011). Adolescents in households lacking a cash margin were more inclined to smoke (OR 1.47, p = 0.033) and to skip breakfast (OR 1.62, p = 0.000) as well as to skip lunch (OR 1.31, p = 0.041) than those in better off households. Not living in a nuclear family was linked with a higher risk of drinking alcohol (OR 1.57, p = 0.002), smoking (OR 2.32, p = 0.000), and skipping breakfast (OR 1.54, p = 0.000) and lunch (OR 1.55, p = 0.000). Adolescents with foreign-born parents were more likely to be physically inactive (OR 1.67, p = 0.001) and to regularly skip breakfast (OR 1.55, p = 0.002) compared with those whose parents were born in Sweden.ConclusionsSociodemographic inequalities in health-related behaviours clearly exist among adolescents in Sweden, along lines of household social class, financial strain, family structure and parental country of birth.

    • In this cross-sectional study, we wanted to identify key cytokines characteristic of different stages of multiple sclerosis (MS). To this end, cerebrospinal fluid from patients with MS was investigated with a multiplexed fluorescent bead-based immunoassay. In total 43 cytokines were assessed and related to clinical and imaging data. Increased levels of CCL22, CXCL10 and sCD40L characterized relapsing-remitting MS patients with the presence of gadolinium-enhancing lesions; decreased CCL2 and increased CXCL1 and CCL5 were typical of relapsing-remitting MS patients irrespectively of the presence of gadolinium-enhancing lesions. These homogenous patterns of cytokine activation do not conform to conventional Th1/Th2/Th17 responses. (C) 2014 Elsevier B.V. All rights reserved.

  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • In this cross-sectional study, we wanted to identify key cytokines characteristic of different stages of multiple sclerosis (MS) that could be used as an outcome measure in clinical trials. To this end, cerebrospinal fluid from a cohort of patients with relapsing-remitting MS (RRMS) and secondary progressive MS (SPMS) was investigated with a multiplexed fluorescent bead-based immunoassay. In total 43 cytokines were assessed and related to clinical and imaging data. Cerebrospinal fluid from a separate confirmatory cohort was used to validate cytokines pertinent to SPMS. Increased levels of CCL22, CXCL10 and sCD40L characterized RRMS patients with presence of gadolinium-enhancing lesions; decreased CCL2 and increased CXCL1 and CCL5 were typical of RRMS patients irrespectively of presence of gadolinium-enhancing lesions. IL-15 and IL-27 were increased in SPMS patients, but non-significantly in the confirmation cohort. These homogenous patterns of cytokine activation do not conform to conventional Th1/Th2/Th17 responses.

  • Influence of Cutting Type and Fertilization in Production of Containerized Poplar Plants
  • 2017
  • Ingår i: Forests. - : MDPI AG. - 1999-4907. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Most poplar plantations are planted on marginal agricultural land, but poplar plantations also hold the potential for increased profits compared to plantations of other species on non-agricultural, previously forested land. To date, the establishment of poplar plantations on previously forested land is limited by the production of suitable containerized poplar stock for planting. The objective of this study is to investigate how different cutting quality and fertilizer treatments influence height, diameter, and root biomass growth and root-to-shoot ratio, all important variables for plant establishment. Our results show that fertilization increases plant growth and that single-bud and two-bud cuttings with cutting diameters of 5 to 10 mm can be used in the production of containerized plants. Root biomass was similar between these plant types but the number of roots per plant was higher if two-bud cuttings were used. In contrast to fertilized plants, only one cutting type (two-bud 10 mm) grew to a sufficient height and diameter for use in poplar plantation establishment. Interestingly, the root-to-shoot ratio for this cutting type was 0.16 while the ratio for the same cutting type is 0.11 if fertilized. Together, these results suggest that most types of poplar cuttings can be used to establish poplar plantations if fertilizer is used and that the largest cutting type (two-bud 10 mm) might be more suitable to establish poplar plantations at harsh sites, thus reducing the cost of poplar plant production.

  • A MicroRNA Gene Panel Predicts the Vaginal Microbiota Composition
  • 2021
  • Ingår i: mSystems. - : American Society for Microbiology. - 2379-5077. ; 6:3
  • Tidskriftsartikel (refereegranskat)abstract
    • The vaginal microbiota plays an essential role in vaginal health. The vaginas of many reproductive-age women are dominated by one of the Lactobacillus species. However, the vaginas of a large number of women are characterized by the colonization of several other anaerobes. Notably, some women with the non-Lactobacillus-dominated vaginal microbiota develop bacterial vaginosis, which has been correlated with sexually transmitted infections and other adverse outcomes. However, interactions and mechanisms linking the vaginal microbiota to host response are still under investigation. There are studies suggesting a link between human microRNAs and gut microbiota, but limited analysis has been carried out on the interplay of microRNAs and vaginal microbiota. In this study, we performed a microRNA expression array profiling on 67 vaginal samples from young Swedish women. MicroRNAs were clustered into distinct groups according to vaginal microbiota composition. Interestingly, 182 microRNAs were significantly elevated in their expression in the non-Lactobacillus-dominated community, suggesting an antagonistic relationship between Lactobacillus and microRNAs. Of the elevated microRNAs, 10 microRNAs displayed excellent diagnostic potential, visualized by receiver operating characteristics analysis. We further validated our findings in 34 independent samples where expression of top microRNA candidates strongly separated the Lactobacillus-dominated community from the non-Lactobacillus-dominated community in the vaginal microbiota. Notably, the Lactobacillus crispatus-dominated community showed the most profound differential microRNA expression compared with the non-Lactobacillus-dominated community. In conclusion, we demonstrate a strong relationship between the vaginal microbiota and numerous genital microRNAs, which may facilitate a deeper mechanistic interplay in this biological niche. IMPORTANCE Vaginal microbiota is correlated with women's health, where a non-Lactobacillus-dominated community predisposes women to a higher risk of disease, including human papillomavirus (HPV). However, the molecular relationship between the vaginal microbiota and host is largely unexplored. In this study, we investigated a link between the vaginal microbiota and host microRNAs in a group of young women. We uncovered an inverse correlation of the expression of microRNAs with the abundance of Lactobacillus species in the vaginal microbiota. Particularly, the expression of microRNA miR-23a-3p and miR-130a-3p, displaying significantly elevated levels in non-Lactobacillus-dominated communities, predicted the bacterial composition of the vaginal microbiota in an independent validation group. Since targeting of microRNAs is explored in the clinical setting, our results warrant investigation of whether microRNA modulation could be used for treating vaginosis recurrence and vaginosis-related diseases. Conversely, commensal bacteria could be used for treating diseases with microRNA aberrations.

  • Tidskriftsartikel (refereegranskat)abstract
    • Human papillomavirus (HPV) infection is one of the most common sexually transmitted diseases. To define the HPV-associated microbial community among a high vaccination coverage population, we carried out a cross-sectional study with 345 young Swedish women. The microbial composition and its association with HPV infection, including 27 HPV types, were analyzed. Microbial alpha-diversity was found significantly higher in the HPV-infected group (especially with oncogenic HPV types and multiple HPV types), compared with the HPV negative group. The vaginal microbiota among HPV-infected women was characterized by a larger number of bacterial vaginosis-associated bacteria (BVAB), Sneathia, Prevotella, and Megasphaera. In addition, the correlation analysis demonstrated that twice as many women with non-Lactobacillus-dominant vaginal microbiota were infected with oncogenic HPV types, compared with L. crispatus-dominated vaginal microbiota. The data suggest that HPV infection, especially oncogenic HPV types, is strongly associated with a non-Lactobacillus-dominant vaginal microbiota, regardless of age and vaccination status.

  • Clinicians' attitudes toward standardized assessment and diagnosis within child and adolescent psychiatry
  • 2019
  • Ingår i: Child and Adolescent Psychiatry and Mental Health. - : Springer Science and Business Media LLC. - 1753-2000. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: There is a strong call for clinically useful standardized assessment tools in everyday child and adolescent psychiatric practice. The attitudes of clinicians have been raised as a key-facilitating factor when implementing new methods. An explorative study was conducted aimed to investigate the clinicians' attitudes regarding standardized assessments and usefulness of diagnoses in treatment planning.Methods: 411 mental health service personnel working with outpatient and inpatient assessment and treatment within the specialist child and adolescent mental health services, Stockholm County Council were asked to participate in the study, of which 345 (84%) agreed answer a questionnaire. The questionnaire included questions regarding Attitudes toward Standardized Assessment and Utility of Diagnosis. Descriptive analyses were performed and four subscales were compared with information from a similar study in US using the same instruments. The demographic and professional characteristics (age, working years, gender, education, profession, management position, involvement in assessment, level of service) in terms of prediction of attitudes were studied by univariate and multivariate linear regressions.Results: Overall, the clinicians had quite positive attitudes and were more positive compared to a similar study conducted in the US earlier. There were differences in attitudes due to several characteristics but the only characteristic predicting all subscales was type of profession (counselor, nurse, psychiatrist, psychologist, other), with counselors being less positive than other groups.Conclusion: The overall positive attitudes toward standard assessment are of importance in the development of evidence-based practice and our study implies that clinicians in general value and are willing to use standardized assessment. Nevertheless, there are specific issues such as adequate training and available translated assessment instrument that need to be addressed. When implementing new methods in practice, there are general as well as specific resistances that need to be overcome. Studies in different cultural settings are of importance to further extend the knowledge of what is general and what is specific barriers.

  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Aim: To investigate the frequency of further interventions after root filling during a follow-up of 10 to 11 years, and to compare the outcomes with respect to type of coronal restoration and tooth group.Methods: Data from the Swedish Social Insurance Agency´s register of dental treatments were obtained to identify the teeth registered as root filled in Sweden 2009. Type of coronal restoration within 6 months after root filling, as well as the frequency of further interventions (nonsurgical retreatment, periradicular surgery, extraction, further direct and indirect restoration) were tracked in the data register until December 31, 2019. Descriptive statistics and Chi-square tests were used for statistical analysis.Results: Of the 215 611 teeth root filled in 2009, nonsurgical retreatment, periradicular surgery, and extraction were registered for 3.5%, 1.4% and 20%, respectively. The highest frequency of nonsurgical retreatment was registered for molars (4.2%), and periradicular surgery was most frequent in maxillary canines and incisors (2.3%). The highest frequency of extractions was registered for mandibular molars (25.1%). Directly restored teeth had higher frequency of nonsurgical retreatment (3.9%) and extraction (20.8%), compared to indirectly restored teeth (1.7% and 13.6%, respectively; P < 0.001). Of teeth restored with direct restoration within 6 months after root filling, 41.5% were registered with at least one further direct restoration and 14.7% with an indirect restoration. In the group of indirectly restored teeth, 9.3% and 7.1% underwent further restorative treatment with direct and indirect restoration, respectively. The differences registered between directly and indirectly restored root filled teeth were statistically significant (P < 0.001).Conclusions: The frequencies of nonsurgical retreatment and periradicular surgery were low 10 to 11 years after root filling, despite one in five root filled teeth being registered as extracted. Further interventions were significantly more common for directly restored teeth than for those indirectly restored.

    • Introduction: The aims were to investigate 1) the frequency of nonsurgical retreatment, root-end surgery, extraction, and further restorative treatment during a follow-up of 10–11 years after root filling and compare the frequencies according to tooth group and type of coronal restoration and 2) the timing of nonsurgical retreatment, root-end surgery, and extraction. Methods: Data were collected from the Swedish Social Insurance Agency's register. A search for treatment codes identified teeth root filled in 2009 and the type of coronal restoration (direct, indirect, and unspecified) registered within 6 months of root filling. The root-filled teeth were followed 10–11 years, and further interventions were recorded. Descriptive statistics and chi-square tests were used for statistical analysis. Results: In 2009, root fillings were registered for 215,611 individuals/teeth. Nonsurgical retreatment, root-end surgery, and extraction were undertaken in 3.5%, 1.4%, and 20% teeth, respectively. The frequency of further interventions varied with respect to tooth group and type of coronal restoration, but only slightly for endodontic retreatments. Further interventions, except for root-end surgery, were registered more often for molars and directly restored teeth (P < .001). The majority of endodontic retreatments were undertaken within 4 years, while extractions were evenly distributed over 10–11 years. Conclusions: The frequency numbers of nonsurgical retreatment and root-end surgery were low, despite 1 in 5 root-filled teeth registered as extracted. Further interventions were most common in molars and directly restored teeth. Endodontic retreatments were performed more often during the first 4 years.

  • High-mobility group box protein 1 and its signalling receptors in human preterm and term cervix
  • 2010
  • Ingår i: Journal of Reproductive Immunology. - : Elsevier BV. - 1872-7603 .- 0165-0378. ; 84:1, s. 86-94
  • Tidskriftsartikel (refereegranskat)abstract
    • The objective of this study was to identify possible changes in mRNA and protein expression of high-mobility group box protein 1 (HMGB1) and its suggested receptors - receptor for advanced glycation end-products (RAGE) and Toll-like receptor 2 (TLR2) and TLR4 - in human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 58 women: 20 at preterm labor, 24 at term labor, 10 at term not in labor and 4 from non-pregnant women. Real-time RT-PCR was used to quantify mRNA expression, and immunohistochemistry and ELISA for protein analysis. HMGB1, RAGE, TLR2 and TLR4 proteins were localized and their mRNA expression was detected in the cervix. There was more extranuclear HMGB1 in the cervical epithelium and stroma in preterm and term labor compared to the term not in labor. TLR2 mRNA expression was upregulated 5-fold in term labor and 3-fold in preterm labor compared to term not in labor and non-pregnant controls. There was lower expression of TLR2 and TLR4 mRNAs in preterm labor compared to term. Lower mRNA expression of HMGB1 was found in the subgroup with preterm premature rupture of membranes than in the rest of the preterm group, where levels were significantly higher than in term labor. In conclusion, extranuclear expression of HMGB1 during labor suggests a possible role of HMGB1 during the process of cervical ripening. Changes in expression of mRNAs encoding HMGB1, TLR2 and TLR4 in preterm labor suggest differences in the mechanism of cervical ripening at preterm and term delivery. (C) 2009 Elsevier Ireland Ltd.

  • Pro-inflammatory and anti-inflammatory cytokines in human preterm and term cervical ripening
  • 2010

    • Cervical ripening is necessary for successful delivery. Since cytokines are believed to be involved in this process, the aim of this study was to investigate possible changes in the mRNA and protein expression of pro-inflammatory cytokines (interleukin (IL)-1 alpha, IL-1 beta, IL-12, IL-18) and anti-inflammatory cytokines (IL-4, IL-10, IL-13)in the human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 59 women: 21 at preterm labor, 24 at term labor, 10 at term not in labor and 4 from non-pregnant women. mRNA was analyzed with real-time RT-PCR and protein expression and/or secretion with immunohistochemistry and ELISA. There was an upregulation of mRNA for IL-10, IL-13, IL-1 alpha and IL-1 beta in the laboring groups, while mRNA for IL-12 and IL-18 was downregulated. IL-4 mRNA was detected more frequently, while IL-12 mRNA expression was lower, in the preterm labor group than in the term labor group. The protein levels of IL-4 and IL-12 were lower and IL-18 tended to be higher in the labor groups, while IL-10 protein levels were unaffected by labor. IL-4 protein levels were significantly higher in the preterm subgroup with bacterial infection than in the non-infected group. IL-10 had higher expression in squamous epithelium at preterm labor than at term. In conclusion, the major changes in pro-inflammatory and anti-inflammatory cytokine mRNA and protein expression in cervix occur during the labor process irrespective of the length of gestation. Our results indicate that dysregulation of anti-inflammatory cytokines in the human cervix could be involved in the pathogenesis of preterm labor.

  • School children's perceptions about being offered the HPV vaccination : A focus group study
  • 2024
  • Ingår i: Acta Paediatrica. - : John Wiley & Sons. - 0803-5253 .- 1651-2227.
  • Tidskriftsartikel (refereegranskat)abstract
    • AimThere is limited knowledge about the perceptions of HPV vaccination in middle-school children. This qualitative study aimed to explore their views.MethodsWe conducted focus group interviews with children, 10–11 years of age, who had been offered HPV vaccination through the school health services in mid-north Sweden in spring of 2023. Data were analysed with qualitative content analysis.ResultsThis study included six focus group interviews with 49 children (boys n = 29; girls n = 20), mean of 11 years of age. Participating children expressed the need to feel safe to be of utmost importance and the means to do so was to be prepared and informed by someone the child trusted. The school nurse was perceived as the expert, best suited to provide factual information, support and motivation, both to children and their parents.ConclusionWe confirm that healthcare providers' recommendations are crucial for HPV vaccine acceptance also from the child's perspective. Improved information about HPV vaccination to children is necessary. Children's right to participate on their own terms is not fulfilled today. Vaccine promotion, both to children and parents, should be actively managed by the school nurse.
