- Objective: To evaluate the systemic phenotype associated with the presence of isolated anti-La/SSB antibodies in a large international registry of patients with primary Sjogren's syndrome (pSS) fulfilling the 2002 classification criteria.Methods: The Big Data Sjogren Project Consortium is an international, multicentre registry created in 2014. Baseline clinical information from leading centres on clinical research in SS of the 5 continents was collected. Combination patterns of anti-Ro/SSA-La/SSB antibodies at the time of diagnosis defined the following four immunological phenotypes: double positive (combined Ro/SSA and La/SSB,) isolated anti-Ro/SSA, isolated anti-La/SSB, and immunonegative.Results: The cohort included 12,084 patients (11,293 females, mean 52.4 years) with recorded ESSDAI scores available. Among them, 279 (2.3%) had isolated anti-La/SSB antibodies. The mean total ESSDAI score at diagnosis of patients with pSS carrying isolated anti-La/SSB was 6.0, and 80.4% of patients had systemic activity (global ESSDAI score >= 1) at diagnosis. The domains with the highest frequency of active patients were the biological (42.8%), glandular (36.8%) and articular (31.2%) domains. Patients with isolated anti-La/ SSB showed a higher frequency of active patients in all ESSDAI domains but two (articular and peripheral nerve) in comparison with immune-negative patients, and even a higher absolute frequency in six clinical ESSDAI domains in comparison with patients with isolated anti-Ro/SSA. In addition, patients with isolated anti-La/SSB showed a higher frequency of active patients in two ESSDAI domains (pulmonary and glandular) with respect to the most active immunological subset (double-positive antibodies). Meanwhile, systemic activity detected in patients with isolated anti-La/SSB was overwhelmingly low. Even in ESSDAI domains where patients with isolated anti-La/SSB had the highest frequencies of systemic activity (lymphadenopathy and muscular), the percentage of patients with moderate or high activity was lower in comparison with the combined Ro/SSA and La/SSB group.Conclusion: Patients carrying isolated La/SSB antibodies represent a very small subset of patients with a systemic SS phenotype characterised by a significant frequency of active patients in most clinical ESSDAI domains but with a relative low frequency of the highest severe organ-specific involvements. Primary SS still remains the best clinical diagnosis for this subset of patients.

- Aim: To analyse the associations between bullying victimisation, disability, and self-reported psychosomatic complaints in adolescents, and to investigate the role of support from parents and teachers in such associations. Methods: The study was based on Finnish and Swedish data from two waves (2013/2014 and 2017/2018) of the Health Behaviour in School-aged Children survey (n=16,057). Descriptive statistics were produced for four groups of adolescents: (a) bullied with disabilities; (b) not bullied with disabilities; (c) bullied without disabilities; and (d) not bullied without disabilities (reference group). Two multilevel multinomial logistic regression models were performed for the Finnish and Swedish samples separately. The first model analysed associations between psychosomatic complaints and bullying victimisation, controlling for a range of confounders. The second model analysed associations between psychosomatic complaints and social support from parents and teachers. Results: Across both countries, bullied adolescents with disabilities were more likely to self-report psychosomatic complaints than the reference group, even after adjusting for other potential confounders. Teacher support was identified as a potential protective factor as the odds ratio for psychosomatic complaints decreased when including teacher support as a factor in the model. The association with parent support showed mixed findings in Finland and Sweden. Conclusions: Disability in combination with bullying victimisation generated the highest levels of self-reported psychosomatic complaints compared to adolescents that were not bullied nor had disabilities. High teacher support may be a protective factor against psychosomatic complaints for bullied and/or disabled adolescents.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To evaluate the influence of the main immunological markers on the disease phenotype at diagnosis in a large international cohort of patients with primary Sjogren's syndrome (SjS).Methods: The Big Data Sjogren Project Consortium is an international, multicentre registry created in 2014. As a first step, baseline clinical information from leading centres on clinical research in SjS of the 5 continents was collected. The centres shared a harmonised data architecture and conducted cooperative online efforts in order to refine collected data under the coordination of a big data statistical team. Inclusion criteria were the fulfillment of the 2002 classification criteria. Immunological tests were carried out using standard commercial assays.Results: By January 2018, the participant centres had included 10,500 valid patients from 22 countries. The cohort included 9,806 (93%) women and 694 (7%) men, with a mean age at diagnosis of primary SjS of 53 years, mainly White (78%) and included from European countries (71%). The frequency of positive immunological markers at diagnosis was 79.3% for ANA, 73.2% for anti-Ro, 48.6% for RF, 45.1% for anti-La, 13.4% for low C3 levels, 14.5% for low C4 levels and 7.3% for cryoglobulins. Positive autoantibodies (ANA, Ro, La) correlated with a positive result in salivary gland biopsy, while hypocomplementaemia and especially cryoglobulinaemia correlated with systemic activity (mean ESSDAI score of 17.7 for ctyoglobulins, 11.3 for low C3 and 9.2 for low C4, in comparison with 3.8 for negative markers). The immunological markers with a great number of statistically-significant associations (p<0.001) in the organ-by-organ ESSDAI evaluation were cryoglobulins (9 domains), low C3 (8 domains), anti-La (7 domains) and low C4 (6 domains).Conclusion: We confirm the strong influence of immunological markers on the phenotype of primary SjS at diagnosis in the largest multi-ethnic international cohort ever analysed, with a greater influence for cryoglobulinaemic-related markers in comparison with Ro/La autoantibodies and ANA. Immunological patterns play a central role in the phenotypic expression of the disease already at the time of diagnosis, and may guide physicians to design a specific personalised management during the follow-up of patients with primary SjS.

Surgical site infection after gastrointestinal surgery in children: an international, multicentre, prospective cohort study
- 2020
-
Ingår i: BMJ global health. - : BMJ. - 2059-7908. ; 5:12
-
Tidskriftsartikel (refereegranskat)abstract
- Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). However, there is a lack of data available about SSI in children worldwide, especially from low-income and middle-income countries. This study aimed to estimate the incidence of SSI in children and associations between SSI and morbidity across human development settings.MethodsA multicentre, international, prospective, validated cohort study of children aged under 16 years undergoing clean-contaminated, contaminated or dirty gastrointestinal surgery. Any hospital in the world providing paediatric surgery was eligible to contribute data between January and July 2016. The primary outcome was the incidence of SSI by 30 days. Relationships between explanatory variables and SSI were examined using multilevel logistic regression. Countries were stratified into high development, middle development and low development groups using the United Nations Human Development Index (HDI).ResultsOf 1159 children across 181 hospitals in 51 countries, 523 (45·1%) children were from high HDI, 397 (34·2%) from middle HDI and 239 (20·6%) from low HDI countries. The 30-day SSI rate was 6.3% (33/523) in high HDI, 12·8% (51/397) in middle HDI and 24·7% (59/239) in low HDI countries. SSI was associated with higher incidence of 30-day mortality, intervention, organ-space infection and other HAIs, with the highest rates seen in low HDI countries. Median length of stay in patients who had an SSI was longer (7.0 days), compared with 3.0 days in patients who did not have an SSI. Use of laparoscopy was associated with significantly lower SSI rates, even after accounting for HDI.ConclusionThe odds of SSI in children is nearly four times greater in low HDI compared with high HDI countries. Policies to reduce SSI should be prioritised as part of the wider global agenda.

Joint Family Activities and Adolescent Health and Wellbeing : Further Considerations Following the War in Ukraine

Tidskriftsartikel (refereegranskat)abstract
- To the Editors:As the authors of the article, “Typologies of Joint Family Activities and Associations With Mental Health and Wellbeing Among Adolescents From Four Countries,” we would like to provide a statement in light of recent events taking place in Eastern Europe [1]. Following the tragic events surrounding the war in Ukraine which started on February 24, 2022, more than half the country’s 7.5 million children have now been displaced [2]. At the time of this paper’s acceptance, hundreds of thousands of refugees making up mostly women and children have travelled to Slovakia, Czechia, and even Russia [3]; countries of focus in the current study. Families have been separated, and the once familiar routines of school and leisure for many Ukrainian children have been replaced with ensuring survival coupled with trauma and unfamiliarity. Lack of housing, malnutrition/hunger, exposure to infectious disease but also deprivation of education, sport, and leisure, are just some of the devastating impacts from armed conflicts on young people’s health and wellbeing [4]. Families from Ukraine will add to the growing number of refugees in the world, a group of over 21 million people who can often struggle with sociocultural differences in the countries they take refuge, as well as accessing information due to language barriers [5]. Many of the most common family activities for the children in our study, such as eating a meal and talking together, will likely present differently or have very different meaning among the hundreds of children who have arrived and will continue to come to these countries. Similarly, the mental health and wellbeing of both those from Ukraine and those from countries geographically close to the conflict will almost certainly suffer following these terrible events. Júnior et al. [4] highlight the importance of addressing children’s psychosocial needs, recommending parents create a safe space that allows for listening to children. As demonstrated in our paper, spending time together with family is important for adolescent’s health wellbeing and may be particularly crucial for families affected by the crisis. We hope that future research surrounding leisure time use and adolescent health considers the needs of marginalized and vulnerable groups of young people in particular, such as those affected and displaced by war and conflict.

- DNA methylation, which is modulated by both genetic factors and environmental exposures, may offer a unique opportunity to discover novel biomarkers of disease-related brain phenotypes, even when measured in other tissues than brain, such as blood. A few studies of small sample sizes have revealed associations between blood DNA methylation and neuropsychopathology, however, large-scale epigenome-wide association studies (EWAS) are needed to investigate the utility of DNA methylation profiling as a peripheral marker for the brain. Here, in an analysis of eleven international cohorts, totalling 3337 individuals, we report epigenome-wide meta-analyses of blood DNA methylation with volumes of the hippocampus, thalamus and nucleus accumbens (NAcc)—three subcortical regions selected for their associations with disease and heritability and volumetric variability. Analyses of individual CpGs revealed genome-wide significant associations with hippocampal volume at two loci. No significant associations were found for analyses of thalamus and nucleus accumbens volumes. Cluster-based analyses revealed additional differentially methylated regions (DMRs) associated with hippocampal volume. DNA methylation at these loci affected expression of proximal genes involved in learning and memory, stem cell maintenance and differentiation, fatty acid metabolism and type-2 diabetes. These DNA methylation marks, their interaction with genetic variants and their impact on gene expression offer new insights into the relationship between epigenetic variation and brain structure and may provide the basis for biomarker discovery in neurodegeneration and neuropsychiatric conditions.

To what extent can urban ventilation features cool a compact built-up environment during a prolonged heatwave? A mesoscale numerical modelling study for Hong Kong
- 2022
-
Ingår i: Sustainable cities and society. - : Elsevier. - 2210-6707. ; 77
-
Tidskriftsartikel (refereegranskat)abstract
- Recent advances in numerical tools and data for the study of urban microclimates have helped to evaluate countermeasures for urban heat in heterogeneous and high-rise cities such as Hong Kong. Thus, two ventilation strategy designs, point ('oases') and linear ('corridors') features, were numerically simulated during a typical heatwave using the multi-layer coupled MesoNH-SURFEX-TEB mesoscale atmospheric model.These strategies proved to be effective at night with respect to thermal comfort but caused a localised increase in heat stress during the day in the ventilated areas, which were less shaded. There was no significant deterioration in the wind performance around the developments that were redesigned to accommodate the displaced population due to the construction of the ventilation features; however, an improvement was observed in thermal comfort during the daytime. The simulated impacts were relatively localised, suggesting the importance of increasing porosity across the entire urban fabric. The corridors, especially when built along the axis of the prevailing winds, exhibited better ventilation at the pedestrian level than the oases. Nevertheless, the oases remain interesting features in the context of progressive urban ventilation planning that involve the implementation of isolated, connected, and eventually a network of features to provide benefits at the megalopolis scale.

- Physical activity (PA) is an important health-promoting behavior from which adolescents with long-term illnesses or disabilities (LTID) can benefit. It is important to monitor differences across countries in adherence with PA recommendations for health. The aim of this study was to compare PA levels among 15 European countries after disaggregating data by disability. Data from pupils (mean age = 13.6 years, SD = 1.64) participating in the 2013/2014 Health Behavior in School-aged Children study were analyzed to compare adolescents without LTID, with LTID, and with LTID that affects their participation (affected LTID). Logistic regression models adjusted for age and family affluence, stratified by gender and country group with PA recommendations for health as the outcome variable. With the data pooled, 15% (n = 9,372) of adolescents reported having LTID and 4% (n = 2,566) having affected LTID. Overall, fewer boys with LTID met PA recommendations for health than boys without LTID, although it was not statistically significant either at the national levels or for girls.

Tidskriftsartikel (refereegranskat)abstract
- Reducing sedentary behaviours can help prevent non-communicable diseases, particularly among young adolescents with long term illnesses or disabilities (LTID). Much of young people’s voluntary sedentary time is related to screen-time behaviours (STBs) such as TV viewing, playing computer games, and using the computer for other activities. Although public health data on adolescents’ STB is growing, information about adolescents with LTID is currently lacking in a European context. The purpose of this study is to compare time on STBs between adolescents with and without LTID in European Countries through the HBSC 2013/14 study. Young adolescents (n = 61,329; boys 47.8%) from 15 European countries reported the time spent on TV viewing, playing computer games, and using the computer for other purposes on weekdays and the weekend. STBs were dichotomised based on international recommendations of less than 2 h per day, and Chi-square tests of independence were performed to investigate differences. STB time was combined to produce a sum score as dependent variable in multiple analysis of covariance with age and family affluence as covariates. There were statistically significant differences in computer gaming among boys and other computer use among girls for both weekdays and weekends, whereby adolescents with LTID reported higher use. In addition, both boys and girls with LTID spent more time on STBs than their same sex peers without LTID (Boys, F = 28.17, p< 0.001; Girls, F = 9.60, p = 0.002). The results of this study indicate a need for preventive strategies to address high levels of STB among young adolescents with LTID and reduce the risk of poor health outcomes associated with higher levels of sedentary behaviour.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study aims to identify distinct typologies of joint family activities and the associations with mental health and wellbeing among adolescents across four countries from the World Health Organization European region.Methods: The 2017/2018 data from adolescents from Armenia (n = 3,977, Mage = 13.5 ± 1.6 years, 53.4% female), Czechia (n = 10,656, Mage = 13.4 ± 1.7, 50.1% female), Russia (n = 4,096, Mage = 13.8 ± 1.7, 52.4% female), and Slovakia (n = 3,282, Mage = 13.4 ± 1.5, 51.0% female) were collected in schools. The respondents self-reported their participation in joint family leisure-time activities, life satisfaction, psychological and somatic complaints, as well as a range of demographic and family situational factors. Stratified by countries, latent class analysis identified typologies of joint family activities, and logistic regression models explored cross-sectional associations with life satisfaction, and psychological and somatic complaints.Results: Three typologies were identified across each of the four countries, distinguished by low, moderate, and high levels of family engagement. Adolescents with higher family engagement generally reported greater life satisfaction and fewer psychological complaints compared to those with lower family engagement. Russian adolescents in the high family engagement typology reported fewer somatic complaints compared to those with low family engagement. In addition, adolescents from Czechia and Russia showing moderate family engagement also reported fewer psychological complaints compared to those in the low family engagement typology. Discussion: Our findings from four countries suggest that adolescents with high family engagement have greater life satisfaction and fewer psychological complaints, pointing toward a need for interventions to support family engagement among adolescents. Further research is needed to fully explore underlying mechanisms.

Influence of the age at diagnosis in the disease expression of primary Sjogren's syndrome : Analysis of 12,753 patients from the Sjogren Big Data Consortium
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Objective. To analyse how the main components of the disease phenotype (sicca symptoms, diagnostic tests, immunological markers and systemic disease) can be driven by the age at diagnosis of primary Sjogren's syndrome (pSS).Methods. By January 2021, the participant centres had included 12,753 patients from 25 countries that fulfilled the 2002/2016 classification criteria for pSS. The age at diagnosis was defined as the time when the attending physician confirmed fulfilment of the criteria. Patients were clustered according to age at diagnosis. 50 clusters with more than 100 observations (from 27 to 76 years) were used to study the influence of the age at diagnosis in the disease expression.Results. There was a consistent increase in the frequency of oral dryness according to the age at diagnosis, with a frequency of <90% in patients diagnosed at the youngest ages and >95% in those diagnosed at the oldest ages. The smooth curves that best fitted a linear model were the frequency of dry mouth (adjusted R-2 0.87) and the frequency of abnormal oral tests (adjusted R-2 0.72). Therefore, for each 1-year increase in the age at diagnosis, the frequency of dry mouth increased by 0.13%, and the frequency of abnormal oral diagnostic tests by 0.11%. There was a consistent year-by-year decrease in the frequency of all autoantibodies and immunological markers except for cryoglobulins. According to the linear models, for each 1-year increase in the age at diagnosis, the frequency of a positive result decreased by 0.57% (for anti-Ro antibodies), 0.47% (for RF) and 0.42% (for anti-La antibodies). The ESSDAI domains which showed a more consistent decrease were glandular and lymph node involvement (for each 1-year increase in the age at diagnosis, the frequency of activity decreased by 0.18%), and constitutional, cutaneous, and haematological involvements (the frequency decreased by 0.09% for each 1-year increase). In contrast, other domains showed an ascending pattern, especially pulmonary involvement (for each 1-year increase in the age at diagnosis, the frequency of activity increased by 0.22%), and peripheral nerve involvement (the frequency increased by 0.09% for each 1-year increase).Conclusion. The influence of the age at diagnosis on the key phenotypic features of pSS is strong, and should be considered critical not only for designing a personalised diagnostic approach, but also to be carefully considered when analysing the results of diagnostic tests and immunological parameters, and when internal organ involvement is suspected at diagnosis.

Tidskriftsartikel (refereegranskat)abstract
- The momentum around computational thinking (CT) has kindled a rising wave of research initiatives andscholarly contributions seeking to capitalize on the opportunities that CT could bring. A number of literaturereviews have showed a vibrant community of practitioners and a growing number of publications. However,the history and evolution of the emerging research topic, the milestone publications that have shaped itsdirections, and the timeline of the important developments may be better told through a quantitative, scientometric narrative. This article presents a bibliometric analysis of the drivers of the CT topic, as well as itsmain themes of research, international collaborations, influential authors, and seminal publications, and howauthors and publications have influenced one another. The metadata of 1,874 documents were retrieved fromthe Scopus database using the keyword “computational thinking.” The results show that CT research has been US-centric from the start, and continues to be dominated by US researchers both in volume and impact. International collaboration is relatively low, but clusters of joint research are found between, for example, anumber of Nordic countries, lusophone- and hispanophone countries, and central European countries. The results show that CT features the computing’s traditional tripartite disciplinary structure (design, modeling, and theory), a distinct emphasis on programming, and a strong pedagogical and educational backdrop including constructionism, self-efficacy, motivation, and teacher training.

Evaluating assumptions of scales for subjective assessment of thermal environments – Do laypersons perceive them the way, we researchers believe?
- 2020
-
Ingår i: Energy and Buildings. - : Elsevier BV. - 0378-7788. ; 211
-
Tidskriftsartikel (refereegranskat)abstract
- People's subjective response to any thermal environment is commonly investigated by using rating scales describing the degree of thermal sensation, comfort, and acceptability. Subsequent analyses of results collected in this way rely on the assumption that specific distances between verbal anchors placed on the scale exist and that relationships between verbal anchors from different dimensions that are assessed (e.g. thermal sensation and comfort) do not change. Another inherent assumption is that such scales are independent of the context in which they are used (climate zone, season, etc.). Despite their use worldwide, there is indication that contextual differences influence the way the scales are perceived and therefore question the reliability of the scales’ interpretation. To address this issue, a large international collaborative questionnaire study was conducted in 26 countries, using 21 different languages, which led to a dataset of 8225 questionnaires. Results, analysed by means of robust statistical techniques, revealed that only a subset of the responses are in accordance with the mentioned assumptions. Significant differences appeared between groups of participants in their perception of the scales, both in relation to distances of the anchors and relationships between scales. It was also found that respondents’ interpretations of scales changed with contextual factors, such as climate, season, and language. These findings highlight the need to carefully consider context-dependent factors in interpreting and reporting results from thermal comfort studies or post-occupancy evaluations, as well as to revisit the use of rating scales and the analysis methods used in thermal comfort studies to improve their reliability.

- Thermal discomfort is one of the main triggers for occupants' interactions with components of the built environment such as adjustments of thermostats and/or opening windows and strongly related to the energy use in buildings. Understanding causes for thermal (dis-)comfort is crucial for design and operation of any type of building. The assessment of human thermal perception through rating scales, for example in post-occupancy studies, has been applied for several decades; however, long-existing assumptions related to these rating scales had been questioned by several researchers. The aim of this study was to gain deeper knowledge on contextual influences on the interpretation of thermal perception scales and their verbal anchors by survey participants. A questionnaire was designed and consequently applied in 21 language versions. These surveys were conducted in 57 cities in 30 countries resulting in a dataset containing responses from 8225 participants. The database offers potential for further analysis in the areas of building design and operation, psycho-physical relationships between human perception and the built environment, and linguistic analyses.

- This study investigates chronic conditions (CC) prevalence among children in mainstream schools, their school experience and life satisfaction in Europe. Data were collected from the 2017/2018 HBSC survey, a cross-national study using self-reported questionnaires administered in classrooms. Nationally representative samples of children aged 11, 13, and 15 years in mainstream schools from 19 European countries (n = 104,812) were used. School experience was assessed using four variables: low school satisfaction, schoolwork pressure, low teacher support, and peer-victimization, which were related to life satisfaction. Latent class analysis (LCA) was conducted to identify patterns of school experience among students with CC. The prevalence of CC varied from 8.4 (Armenia) to 28.2% (Finland). Children with CC (n = 17,514) rated their school experience and life satisfaction lower than children without CC. LCA identified three school experience patterns: "negative on all items" (37%), "negative on all items, except school pressure" (40%) and "overall positive" (23%). The distribution of subgroups varied across countries-in countries with a higher proportion of children with CC in mainstream schools, children reported more negative school experiences. Compared to the "overall positive" group, low life satisfaction was highest for students classified as "negative on all items" (relative risk (RR) = 2.9; 95% CI 2.2-3.8) with a lesser effect for "negative on all items, except school pressure" (RR) = 1.8; 95% CI 1.4-2.4). These findings provide cross-national data documenting the diversity in inclusive educational practices regarding school placement and school experiences, and suggest that efforts are still needed to allow a fully inclusive environment.
