- Patients with chronic lymphocytic leukemia (CLL) assigned to stereotyped subset #4 express highly homologous B-cell receptor immunoglobulin (BcR IG) sequences with intense intraclonal diversification (ID) in the context of ongoing somatic hypermutation (SHM). Their remarkable biological and clinical similarities strongly support derivation from a common ancestor. We here revisited ID in subset #4 CLL in order to reconstruct their evolutionary history as a community of related clones. To this end, using specialized bioinformatics tools we assessed both IGHV-IGHD-IGHJ rearrangements (n=511) and IGKV-IGKJ rearrangements (n=397) derived from 8 subset #4 cases. Due to high sequence relatedness, a number of subclonal clusters from different cases lay very close to one another, forming a core from which clusters exhibiting greater variation stemmed. Minor subclones from individual cases were mutated to such an extent that they now resembled the sequences of another patient. Viewing the entire subset #4 dataset as a single entity branching through diversification, enabled inference of a common sequence representing the putative ancestral BcR IG expressed by their still elusive common progenitor. These results have implications for improved understanding of the ontogeny of CLL subset #4, as well as the design of studies concerning the antigenic specificity of the clonotypic BcR IGs.

- 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.

- IntroductionGender affirming surgery of primary and/or secondary sex characteristics has been shown to alleviate gender dysphoria. A descriptive snapshot of current treatment preferences is useful to understand the needs of the transgender population seeking health care. This study aimed to describe preferences for gender affirming treatment, and their correlates, among individuals seeking health care for gender dysphoria in Sweden after major national legislative reforms.MethodsCross-sectional study where transgender patients (n = 232) recruited from all six Gender Dysphoria centers in Sweden 2016–2019, answered a survey on treatment preferences and sociodemographic, health, and gender identity-related information during the same time-period. Factors associated with preferring top surgery (breast augmentation or mastectomy), genital surgery, and other surgery (e.g., facial surgery) were examined in univariable and multivariable regression analyses in the 197 people without prior such treatment. Main study outcomes were preferences for feminizing or masculinizing hormonal and surgical gender affirming treatment.ResultsThe proportion among birth assigned male and assigned female patients preferring top surgery was 55.6% and 88.7%, genital surgery 88.9% and 65.7%, and other surgery (e.g., facial surgery) 85.6% and 22.5%, respectively. Almost all participants (99.1%) wanted or had already received hormonal treatment and most (96.7%) wished for some kind of surgical treatment; 55.0% wanted both top and genital surgery. Preferring a binary pronoun (he/she) and factors indicating more severe gender incongruence were associated with a greater wish for surgical treatment. Participants with somatic comorbidities were less likely to want genital surgery, while aF with lacking social support were less likely to want internal genital surgery, in the multivariable analyses.ConclusionsIn this sample of Swedish young adults seeking health care for gender dysphoria, preferences for treatment options varied according to perceived gender identity.Policy ImplicationsThe study fndings underline the need for individualized care and fexible gender afrming treatmentoptions. The role of somatic comorbidities should be further explored, and support should be ofered to transgender peoplein need. There is an unmet need for facial surgery among aM

Tidskriftsartikel (refereegranskat)abstract
- Antenatal depression affects similar to 9-19% of pregnant women and can exert persistent adverse effects on both mother and child. There is a need for a deeper understanding of antenatal depression mechanisms and the development of tools for reliable diagnosis and early identification of women at high risk. As the use of untargeted blood metabolomics in the investigation of psychiatric and neurological diseases has increased substantially, the main objective of this study was to investigate whether untargeted gas chromatography-mass spectrometry (GC-MS) plasma metabolomics in 45 women in late pregnancy, residing in Uppsala, Sweden, could indicate metabolic differences between women with and without depressive symptoms. Furthermore, seasonal differences in the metabolic profiles were explored. When comparing the profiles of cases with controls, independently of season, no differences were observed. However, seasonal differences were observed in the metabolic profiles of control samples, suggesting a favorable cardiometabolic profile in the summer vs. winter, as indicated by lower glucose and sugar acid concentrations and lactate to pyruvate ratio, and higher abundance of arginine and phosphate. Similar differences were identified between cases and controls among summer pregnancies, indicating an association between a stressed metabolism and depressive symptoms. No depression-specific differences were apparent among depressed and non-depressed women, in the winter pregnancies; this could be attributed to an already stressed metabolism due to the winter living conditions. Our results provide new insights into the pathophysiology of antenatal depression, and warrant further investigation of the use of metabolomics in antenatal depression in larger cohorts.

Seasonal aspects of peripartum depressive symptoms
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Every year, a large proportion of pregnant and newly delivered women develop peripartum depression, a condition that may cause long-term suffering for the entire family. Although there is a lack of consensus, some studies propose an association between season and the risk of developing depression during pregnancy and the postpartum period. Furthermore, the immune system, which undergoes numerous structural changes during pregnancy, has been suggested to exhibit seasonal variations. In addition, discrepancies in metabolic profiles have been reported between women with and without depression after childbirth. This thesis aimed to investigate seasonal aspects of peripartum depressive symptoms (PPDS) and biological markers during the peripartum period. The data mainly derived from the prospective population-based Biology, Affect, Stress, Imaging, and Cognition (BASIC) study, but data were also included from the longitudinal population-based Uppsala-Athens (UPPSAT) study. The presence of depressive symptoms was primarily assessed using the Edinburgh Postnatal Depression Scale (EPDS). There were no consistent associations between season, meteorological parameters, air pollen count, and PPDS. Moreover, a number of inflammatory markers were identified as having seasonal variations among samples from pregnant women. On the contrary, only one marker had a seasonal pattern during the early postpartum period. Furthermore, metabolic profiles were not discriminatory between pregnant women with and without depressive symptoms. However, when divided into summer and winter childbirths, discrepancies were identified in metabolic profiles between summer cases and controls, as well as between summer and winter controls. In summary, the studies included in this thesis suggest that season, specifically, is not associated with PPDS. However, season may have a moderating effect on the association between depressive symptoms and the metabolic profile of pregnant women. In addition, the seasonal variations appears more prominent among inflammatory markers during late pregnancy, compared with the early postpartum period. These findings suggest that women need equal attention in clinical care regardless of the season during which they give birth. Future studies on biological aspects of PPDS and immune-associated conditions are encouraged to also assess seasonality.

Tidskriftsartikel (refereegranskat)abstract
- Seasonal variations have recently been described in biomarkers, cell types, and gene expression associated with the immune system, but so far no studies have been conducted among women in the peripartum period. It is of note that pregnancy complications and outcomes, as well as autoimmune diseases, have also been reported to exhibit seasonal fluctuations. We report here a clear-cut seasonal pattern of 23 inflammatory markers, analysed using proximity-extension assay technology, in pregnant women. The inflammatory markers generally peaked in the spring and had a trough in the autumn. During the postpartum period we found seasonality in one inflammatory marker, namely monocyte chemotactic protein 4 (MCP-4). Our findings suggest that seasonal variations in peripheral inflammatory markers are only observed during pregnancy. The results of this study could be valuable to professionals working within the field of immunology-related areas, and provide insight for the understanding of obstetric complications.

- IntroductionThe Hypothalamic-Pituitary-Adrenal Axis (HPA axis) has been implicated in the pathogenesis of many affective disorders. Peripartum depression is a condition that includes depressive episodes occurring during pregnancy and the postpartum period. During uncomplicated pregnancy, mean cortisol levels rise substantially, mostly due to high levels of corticotropin releasing hormone produced by the placenta (p-CRH). The latter also suppresses hypothalamic CRH, leading to hypo-cortisolemia after partus. Cortisol concentration is usually normalised within two weeks after delivery. Failure of the above process results in continuing hypo-cortisolemia, which might increase susceptibility to PPD.Objectives/aimsThe current study aims to investigate the relationship between evening salivary cortisol levels and depression during the peripartum period.MethodsThree hundred and forty six pregnant women were asked to participate in the study. They completed the Edinburgh Postnatal Depression Scale (EPDS) and the Spielberger State-Trait Anxiety Inventory-State version (STAI-S) at the 36th week of pregnancy and the 6th week after delivery. At both times, study subjects were also asked to collect evening salivary samples by using a mail-delivered kit. Moreover, they were interviewed at the 36th week of pregnancy using the Mini International Neuropsychiatric Interview (MINI).ResultsPreliminary results indicate significantly higher evening salivary cortisol levels in depressed women during late pregnancy compared to healthy controls. No difference in cortisol levels was found between women with postpartum depression and healthy controls.ConclusionsOur study results support the hypothesis that depression during pregnancy resembles melancholic depression characterized by hyperactivity of the HPA-axis and hyper-cortisolemia.

- Postpartum depression (PPD) is a common childbirth complication, affecting 10-15 % of newly delivered mothers. This study aims to assess the association between personality factors and PPD. All pregnant women during the period September 2009 to September 2010, undergoing a routine ultrasound at Uppsala University Hospital, were invited to participate in the BASIC study, a prospective study designed to investigate maternal well-being. Depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) while the Depression Self-Rating Scale (DSRS) was used as a diagnostic tool for major depression. Personality traits were evaluated using the Swedish Universities Scale of Personality (SSP). One thousand thirty-seven non-depressed pregnant women were included in the study. Non-depressed women reporting high levels of neuroticism in late pregnancy were at high risk of developing postpartum depressive symptoms (PPDSs) at 6 weeks and 6 months after delivery, even after adjustment for confounders (adjusted odds ratio (aOR) = 3.4, 95 % confidence interval (CI) 1.8-6.5 and adjusted odds ratio (aOR) = 3.9, 95 % CI 1.9-7.9). The same was true for a DSRS-based diagnosis of major depression at 6 months postpartum. Somatic trait anxiety and psychic trait anxiety were associated with increased risk for PPDS at 6 weeks (aOR = 2.1, 95 % CI 1.2-3.5 and aOR = 1.9, 95 % CI 1.1-3.1), while high scores of mistrust were associated with a twofold increased risk for PPDS at 6 months postpartum (aOR 1.9, 95 % CI 1.1-3.4). Non-depressed pregnant women with high neuroticism scores have an almost fourfold increased risk to develop depressive symptoms postpartum, and the association remains robust even after controlling for most known confounders. Clinically, this could be of importance for health care professionals working with pregnant and newly delivered women.

Tidskriftsartikel (refereegranskat)abstract
- The Transgender Congruence Scale (TCS) is a non-binary tool used in Sweden for gender dysphoria (GD) assessment; however, its Swedish version has not been validated. To investigate the psychometric properties of the TCS, its capacity to distinguish individuals with GD and its concurrent validity compared to other scales. Patients with GD (n=135) and controls (n=443) filled in a questionnaire containing sociodemographic questions, the TCS, the Utrecht Gender Dysphoria Scale (UGDS), and the Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults (GIDYQ-AA). TCS had good discriminatory validity and internal consistency. Patients with GD, stratified by birth-assigned sex, had lower TCS scores compared to controls. Confirmatory factor analysis (CFA) supported the two-factor model of the TCS. Multiple-group CFA suggested measurement invariance between birth-assigned sexes and configural invariance between patients with GD and controls. Area under the ROC curve for birth-assigned males was 0.991 and for females 0.994. A TCS mean value of three provided sensitivity 94.3% and 95.1% as well as specificity 98.6% and 98% for aM and aF, respectively. The TCS was significantly correlated to UGDS and GIDYQ-AA. The TCS may be a valuable tool in the clinical assessment of individuals with GD.

Self-Harm Thoughts Postpartum as a Marker for Long-Term Morbidity
- 2018
-
Ingår i: Frontiers In Public Health. - : Frontiers Media SA. - 2296-2565. ; 6

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Postpartum depression predisposes to maternal affective and somatic disorders. It is important to identify which women are at an increased risk of subsequent morbidity and would benefit from an intensified follow-up. Self-harm thoughts (SHTs), with or without other depressive symptomatology, might have prognostic value for maternal health beyond the postpartum period.Aim: This study is to investigate the somatic and psychiatric morbidity of postpartum women with SHTs, with or without other depressive symptoms, over a 7-year follow-up period.Materials and methods: The subjects for this study are derived from a population based Swedish cohort of women who gave birth at Uppsala University Hospital (May 2006-June 2007) and who answered the Edinburgh Postnatal Depression Scale (EPDS) at 5 days, 6 weeks, and 6 months postpartum. Three groups were included: women reporting SHTs (SHT group, n = 107) on item 10 of the EPDS; women reporting depressive symptoms, i.e., EPDS >= 12 at 6 weeks and/or 6 months postpartum, without SHTs (DEP group, n = 94); and randomly selected controls screening negatively for postpartum depression (CTL group, n = 104). The number of diagnostic codes for somatic and psychiatric morbidity according to the International Statistical Classification of Diseases and Related Health Problems system, and the number of medical interventions were retrieved from medical records over 7 years following childbirth and were used as the outcome measures, together with any prescription of antidepressants and sick leave during the follow-up.Results: The SHT group had the highest psychiatric morbidity of all groups and more somatic morbidity than controls. Affective disorders were more common in the SHT and the DEP groups compared with controls, as well as antidepressant prescriptions and sick leave. One-fifth of women with SHTs did not screen positive for depressive symptoms; nevertheless, they had more somatic and psychiatric morbidity than the control group.Conclusion: Women reporting thoughts of self-harm in the postpartum period are at an increased risk of somatic and psychiatric morbidity during a follow-up of 7 years after delivery, and this increased risk may not be fully attributed to depressive symptoms. Results underline the importance of screening for self-harm symptoms postpartum and point to a need for individualized follow-up.
