- OBJECTIVE: To derive cluster analysis-based groupings for adults with congenital heart disease (ACHD) when it comes to perceived health, psychological functioning, health behaviours and quality of life (QoL).METHODS: This study was part of a larger worldwide multicentre study called APPROACH-IS; a cross sectional study which recruited 4028 patients (2013-2015) from 15 participating countries. A hierarchical cluster analysis was performed using Ward's method in order to group patients with similar psychological characteristics, which were defined by taking into consideration the scores of the following tests: Sense Of Coherence, Health Behavior Scale (physical exercise score), Hospital Anxiety Depression Scale, Illness Perception Questionnaire, Satisfaction with Life Scale and the Visual Analogue Scale scores of the EQ-5D perceived health scale and a linear analogue scale (0-100) measuring QoL.RESULTS: 3768 patients with complete data were divided into 3 clusters. The first and second clusters represented 89.6% of patients in the analysis who reported a good health perception, QoL, psychological functioning and the greatest amount of exercise. Patients in the third cluster reported substantially lower scores in all PROs. This cluster was characterised by a significantly higher proportion of females, a higher average age the lowest education level, more complex forms of congenital heart disease and more medical comorbidities.CONCLUSIONS: This study suggests that certain demographic and clinical characteristics may be linked to less favourable health perception, quality of life, psychological functioning, and health behaviours in ACHD. This information may be used to improve psychosocial screening and the timely provision of psychosocial care.

- Background Atrial arrhythmias (ie, intra-atrial reentrant tachycardia and atrial fibrillation) are a leading cause of morbidity and hospitalization in adults with congenital heart disease (CHD). Little is known about their effect on quality of life and other patient-reported outcomes (PROs) in adults with CHD. Objective The purpose of this study was to assess the impact of atrial arrhythmias on PROs in adults with CHD and explore geographic variations. Methods Associations between atrial arrhythmias and PROs were assessed in a cross-sectional study of adults with CHD from 15 countries spanning 5 continents. A propensity-based matching weight analysis was performed to compare quality of life, perceived health status, psychological distress, sense of coherence, and illness perception in patients with and those without atrial arrhythmias. Results A total of 4028 adults with CHD were enrolled, 707 (17.6%) of whom had atrial arrhythmias. After applying matching weights, patients with and those without atrial arrhythmias were comparable with regard to age (mean 40.1 vs 40.2 years), demographic variables (52.5% vs 52.2% women), and complexity of CHD (15.9% simple, 44.8% moderate, and 39.2% complex in both groups). Patients with atrial arrhythmias had significantly worse PRO scores with respect to quality of life, perceived health status, psychological distress (ie, depression), and illness perception. A summary score that combines all PRO measures was significantly lower in patients with atrial arrhythmias (-3.3%; P = .0006). Differences in PROs were consistent across geographic regions. Conclusion Atrial arrhythmias in adults with CHD are associated with an adverse impact on a broad range of PROs consistently across various geographic regions.

- Background: Health behaviours are essential to maintain optimal health and reduce the risk of cardiovascular complications in adults with congenital heart disease. This study aimed to describe health behaviours in adults with congenital heart disease in 15 countries and to identify patient characteristics associated with optimal health behaviours in the international sample. Design: This was a cross-sectional observational study. Methods: Adults with congenital heart disease (n = 4028, median age = 32 years, interquartile range 25–42 years) completed self-report measures as part of the Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease - International Study (APPROACH-IS). Participants reported on seven health behaviours using the Health Behaviors Scale-Congenital Heart Disease. Demographic and medical characteristics were assessed via medical chart review and self-report. Multivariate path analyses with inverse sampling weights were used to investigate study aims. Results: Health behaviour rates for the full sample were 10% binge drinking, 12% cigarette smoking, 6% recreational drug use, 72% annual dental visit, 69% twice daily tooth brushing, 27% daily dental flossing and 43% sport participation. Pairwise comparisons indicated that rates differed between countries. Rates of substance use behaviours were higher in younger, male participants. Optimal dental health behaviours were more common among older, female participants with higher educational attainment while sports participation was more frequent among participants who were younger, male, married, employed/students, with higher educational attainment, less complex anatomical defects and better functional status. Conclusions: Health behaviour rates vary by country. Predictors of health behaviours may reflect larger geographic trends. Our findings have implications for the development and implementation of programmes for the assessment and promotion of optimal health behaviours in adults with congenital heart disease. © The European Society of Cardiology 2019.

- Background: A comprehensive understanding of adult congenital heart disease outcomes must include psychological functioning. Our multisite study offered the opportunity to explore depression and anxiety symptoms within a global sample.Objectives: In this substudy of the APPROACH-IS (Assessment of Patterns of Patient-Reported Outcomes in Adults With Congenital Heart Disease–International Study), the authors we investigated the prevalence of elevated depression and anxiety symptoms, explored associated sociodemographic and medical factors, and examined how quality of life (QOL) and health status (HS) differ according to the degree of psychological symptoms.Methods: Participants completed the Hospital Anxiety and Depression Scale, which includes subscales for symptoms of anxiety (HADS-A) and depression (HADS-D). Subscale scores of 8 or higher indicate clinically elevated symptoms and can be further categorized as mild, moderate, or severe. Participants also completed analogue scales on a scale of 0 to 100 for QOL and HS. Analysis of variance was performed to investigate whether QOL and HS differed by symptom category.Results: Of 3,815 participants from 15 countries (age 34.8 ± 12.9 years; 52.7% female), 1,148 (30.1%) had elevated symptoms in one or both subscales: elevated HADS-A only (18.3%), elevated HADS-D only (2.9%), or elevations on both subscales (8.9%). Percentages varied among countries. Both QOL and HS decreased in accordance with increasing HADS-A and HADS-D symptom categories (P < 0.001).Conclusions: In this global sample of adults with congenital heart disease, almost one-third reported elevated symptoms of depression and/or anxiety, which in turn were associated with lower QOL and HS. We strongly advocate for the implementation of strategies to recognize and manage psychological distress in clinical settings.

Pain in adults with congenital heart disease : An international perspective
- 2021
-
Ingår i: International Journal of Cardiology Congenital Heart Disease. - : Elsevier. - 2666-6685. ; 5
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Patients with adult congenital heart disease (ACHD) have many risk factors for chronic pain such as prior cardiac interventions and adult comorbidities. However, the prevalence of chronic pain has not been well described in this population. We sought to determine the prevalence of pain in a large international cohort of patients with ACHD.Methods: Data from the APPROACH-IS dataset was utilized for this study which includes 4028 patients with ACHD from 15 different countries. The prevalence of pain was assessed under the health status patient reported outcome domain utilizing the EuroQol-5D 3 level version tool. Multivariable logistic regression was used to assess differences across countries in pain, taking into account country-level random effects for clustering across observations within each country.Results: A total of 3832 patients with ACHD met the study criteria, median age 32 years [IQR 25, 42], 52.6% females. The prevalence of at least moderate pain was reported by 28.9% (95% CO 27.5 = 30.3%) of participants. Pain was associated with country of origin, age, gender, background, education and marital status as well as several clinical variables including disease complexity, cardiac device presence, history of heart failure, psychiatric conditions and presence of other medical conditions. Those with pain had lower levels of perceived health and a lower quality of life score.Conclusion: Pain in patients with ACHD is common, impacting nearly one-third of patients. Given the far reaching implications of pain in patients with ACHD, further study of pain characteristics and treatment management appear warranted.

- BACKGROUND: Implantable cardioverter-defibrillators (ICDs) are increasingly used to prevent sudden deaths in the growing population of adults with congenital heart disease (CHD). Yet, little is known about their impact on patient-reported outcomes (PROs).OBJECTIVE: We assessed and compared PROs in adults with CHD with and without ICDs.METHODS: A propensity-based matching weight analysis was conducted to evaluate PROs in an international cross-sectional study of adults with CHD from 15 countries across 5 continents.RESULTS: A total of 3,188 patients were included: 107 with ICDs and 3,081 weight-matched controls without ICDs. ICD recipients averaged 40.1±12.4 years of age, with >95% having moderate or complex CHD. Defibrillators were implanted for primary and secondary prevention in 38.3% and 61.7%, respectively. Perceived health status, psychological distress, sense of coherence, and health behaviours did not differ significantly in patients with and without ICDs. However, ICD recipients had a more threatening view of their illness (relative % difference 8.56, P=0.011). Those with secondary compared to primary prevention indications had a significantly lower quality of life score (linear analogue scale 72.0±23.1 versus 79.2±13.0, P=0.047). Marked geographic variations were observed. Overall sense of well-being, assessed by a summary score that combines various PROs, was significantly lower in ICD recipients (versus controls) from Switzerland, Argentina, Taiwan, and USA.CONCLUSIONS: In an international cohort of adults with CHD, ICDs were associated with a more threatening illness perception, with a lower quality of life in those with secondary compared to primary prevention indications. However, marked geographic variability in PROs was observed.

Reputation versus office : Why populist radical right governmental participation has differed between Sweden and Denmark

Tidskriftsartikel (refereegranskat)abstract
- Sweden and Denmark have presented contrasting relationships between centre-right and populist radical right (PRR) parties. In Sweden, the centre-right has refused cooperation with the Sweden Democrats (Sverigedemokraterna) (SD), even when this cost the centre-right office. However, in Denmark, coalitions led by centre-right parties have cooperated with the Danish People’s Party (Dansk Folkeparti) (DF) on multiple occasions. Through a controlled comparison, we examine what explains these different outcomes. Using Chapel Hill Expert Surveys and public opinion data, we firstly look at the policy congruence between parties and the social acceptability of cooperation. We then examine interview material with representatives from centre-right and PRR parties in Sweden and Denmark to see their explanations of cooperation and non-cooperation. We conclude that, while the office goals of Danish centre-right parties, along with the policy focus and uncontroversial past of DF, explain that case, the reputation and past of SD has precluded a similar outcome.

- In this international study, we (1) compared patient-reported outcomes (PROs) in adults with congenital heart disease (CHD) who had versus had not been hospitalized during the previous 12 month, (2) contrasted PROs in patients who had been hospitalized for cardiac surgery versus nonsurgical reasons, (3) assessed the magnitude of differences between the groups (i.e., effect sizes), and (4) explored differential effect sizes between countries. APPROACH-IS was a cross-sectional, observational study that enrolled 4,028 patients from 15 countries (median age 32 years; 53% females). Self-report questionnaires were administered to measure PROs: health status; anxiety and depression; and quality of life. Overall, 668 patients (17%) had been hospitalized in the previous 12 months. These patients reported poorer outcomes on all PROs, with the exception of anxiety. Patients who underwent cardiac surgery demonstrated a better quality of life compared with those who were hospitalized for nonsurgical reasons. For significant differences, the effect sizes were small, whereas they were negligible in nonsignificant comparisons. Substantial intercountry differences were observed. For various PROs, moderate to large effect sizes were found comparing different countries. In conclusion, adults with CHD who had undergone hospitalization in the previous year had poorer PROs than those who were medically stable. Researchers ought to account for the timing of recruitment when conducting PRO research as hospitalization can impact results.

- The congenital heart disease (CHD) population now comprises an increasing number of older persons in their 6th decade of life and beyond. We cross-sectionally evaluated patient-reported outcomes (PROs) in persons with CHD aged 60 years or older, and contrasted these with PROs of younger patients aged 40-59 years and 18-39 years. Adjusted for demographic and medical characteristics, patients ≥60 years had a lower Physical Component Summary, higher Mental Component Summary, and lower anxiety (Hospital Anxiety and Depression Scale-Anxiety) scores than patients in the two younger categories. For satisfaction with life, older persons had a higher score than patients aged 40-59 years. Registration: ClinicalTrials.gov NCT02150603.

Physical Functioning, Mental Health, and Quality of Life in Different Congenital Heart Defects : Comparative Analysis in 3538 Patients From 15 Countries
- 2021

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: We compared physical functioning, mental health, and quality of life (QoL) of patients with different subtypes of congenital heart disease (CHD) in a large international sample and investigated the role of functional class in explaining the variance in outcomes across heart defects.METHODS: In the cross-sectional Assessment of Patterns of Patient-Reported Outcome in Adults with Congenital Heart Disease-International Study (APPROACH-IS), we enrolled 4028 adult patients with CHD from 15 countries. Diagnostic groups with at least 50 patients were included in these analyses, yielding a sample of 3538 patients (median age: 32 years; 52% women). Physical functioning, mental health, and QoL were measured with the SF-12 health status survey, Hospital Anxiety and Depression Scale (HADS), linear analog scale (LAS) and Satisfaction with Life Scale, respectively. Functional class was assessed using the patient-reported New York Heart Association (NYHA) class. Multivariable general linear mixed models were applied to assess the relationship between the type of CHD and patient-reported outcomes, adjusted for patient characteristics, and with country as random effect.RESULTS: Patients with coarctation of the aorta and those with isolated aortic valve disease reported the best physical functioning, mental health, and QoL. Patients with cyanotic heart disease or Eisenmenger syndrome had worst outcomes. The differences were statistically significant, above and beyond other patient characteristics. However, the explained variances were small (0.6% to 4.1%) and decreased further when functional status was added to the models (0.4% to 0.9%).CONCLUSIONS: Some types of CHD predict worse patient-reported outcomes. However, it appears that it is the functional status associated with the heart defect rather than the heart defect itself that shapes the outcomes.

-
Ingår i: European Journal of Cardiovascular Nursing. - : Oxford University Press. - 1474-5151 .- 1873-1953. ; 20:1, s. 48-55

Tidskriftsartikel (refereegranskat)abstract
- Background: Previous studies have found that sense of coherence (SOC) is positively related to quality of life (QoL) in persons with chronic conditions. In congenital heart disease (CHD), the evidence is scant.Aims: We investigated (i) intercountry variation in SOC in a large international sample of adults with CHD; (ii) the relationship between demographic and clinical characteristics and SOC; (iii) the relationship between cultural dimensions of countries and SOC; and (iv) variation in relative importance of SOC in explaining QoL across the countries.Methods: APPROACH-IS was a cross-sectional, observational study, with 4028 patients from 15 countries enrolled. SOC was measured using the 13-item SOC scale (range 13–91) and QoL was assessed by a linear analog scale (range 0–100).Results: The mean SOC score was 65.5±13.2. Large intercountry variation was observed with the strongest SOC in Switzerland (68.8±11.1) and the lowest SOC in Japan (59.9±14.5). A lower SOC was associated with a younger age; lower educational level; with job seeking, being unemployed or disabled; unmarried, divorced or widowed; from a worse functional class; and simple CHD. Power distance index and individualism vs collectivism were cultural dimensions significantly related to SOC. SOC was positively associated with QoL in all participating countries and in the total sample, with an explained variance ranging from 5.8% in Argentina to 30.4% in Japan.Conclusion: In adults with CHD, SOC is positively associated with QoL. The implementation of SOC-enhancing interventions might improve QoL, but strategies would likely differ across countries given the substantial variation in explained variance.

Konferensbidrag (refereegranskat)abstract
- We investigate how teaching in practice can stimulate students to become better at handling digital information critically and constructively, in different contexts.In the form of a design study where professional teachers and researchers together develop and test different arrangements in teaching, we examine thequestion of how varying materials and teaching methods can support students' digital source criticism in five different school subjects, namely, history, civics,art, psychology and biology. Teachers technological pedagogical content knowledge (Mishra & Koehler, 2006) is at the core of the design iterations aimed atinvestigating educational innovative designs with a positive impact in ordinary messy classrooms. The results highlight how TPACK reflections in relation todesign iterations may promote students’ abilities to identify, evaluate and use digital information in critical and constructive ways in different school subjects. Wealso present and discuss what students learn and struggle to learn in the five subject specific settings in light of research highlighting the importance of digitalcivic literacy.

Regional variability in peatland burning at mid-to high-latitudes during the Holocene
- 2023
-
Ingår i: Quaternary Science Reviews. - : Elsevier. - 0277-3791 .- 1873-457X. ; 305
-
Tidskriftsartikel (refereegranskat)abstract
- Northern peatlands store globally-important amounts of carbon in the form of partly decomposed plant detritus. Drying associated with climate and land-use change may lead to increased fire frequency and severity in peatlands and the rapid loss of carbon to the atmosphere. However, our understanding of the patterns and drivers of peatland burning on an appropriate decadal to millennial timescale relies heavily on individual site-based reconstructions. For the first time, we synthesise peatland macrocharcoal re-cords from across North America, Europe, and Patagonia to reveal regional variation in peatland burning during the Holocene. We used an existing database of proximal sedimentary charcoal to represent regional burning trends in the wider landscape for each region. Long-term trends in peatland burning appear to be largely climate driven, with human activities likely having an increasing influence in the late Holocene. Warmer conditions during the Holocene Thermal Maximum (similar to 9e6 cal. ka BP) were associated with greater peatland burning in North America's Atlantic coast, southern Scandinavia and the Baltics, and Patagonia. Since the Little Ice Age, peatland burning has declined across North America and in some areas of Europe. This decline is mirrored by a decrease in wider landscape burning in some, but not all sub-regions, linked to fire-suppression policies, and landscape fragmentation caused by agricultural expansion. Peatlands demonstrate lower susceptibility to burning than the wider landscape in several instances, probably because of autogenic processes that maintain high levels of near-surface wetness even during drought. Nonetheless, widespread drying and degradation of peatlands, particularly in Europe, has likely increased their vulnerability to burning in recent centuries. Consequently, peatland restoration efforts are important to mitigate the risk of peatland fire under a changing climate. Finally, we make recommendations for future research to improve our understanding of the controls on peatland fires.(c) 2023 The Authors. Published by Elsevier Ltd.

Healthcare system inputs and patient-reported outcomes : a study in adults with congenital heart defect from 15 countries
- 2020
-
Ingår i: BMC Health Services Research. - : Springer Science and Business Media LLC. - 1472-6963. ; 20:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The relationship between healthcare system inputs (e.g., human resources and infrastructure) and mortality has been extensively studied. However, the association between healthcare system inputs and patient-reported outcomes remains unclear. Hence, we explored the predictive value of human resources and infrastructures of the countries' healthcare system on patient-reported outcomes in adults with congenital heart disease.METHODS: This cross-sectional study included 3588 patients with congenital heart disease (median age = 31y; IQR = 16.0; 52% women; 26% simple, 49% moderate, and 25% complex defects) from 15 countries. The following patient-reported outcomes were measured: perceived physical and mental health, psychological distress, health behaviors, and quality of life. The assessed inputs of the healthcare system were: (i) human resources (i.e., density of physicians and nurses, both per 1000 people) and (ii) infrastructure (i.e., density of hospital beds per 10,000 people). Univariable, multivariable, and sensitivity analyses using general linear mixed models were conducted, adjusting for patient-specific variables and unmeasured country differences.RESULTS: Sensitivity analyses showed that higher density of physicians was significantly associated with better self-reported physical and mental health, less psychological distress, and better quality of life. A greater number of nurses was significantly associated with better self-reported physical health, less psychological distress, and less risky health behavior. No associations between a higher density of hospital beds and patient-reported outcomes were observed.CONCLUSIONS: This explorative study suggests that density of human resources for health, measured on country level, are associated with patient-reported outcomes in adults with congenital heart disease. More research needs to be conducted before firm conclusions about the relationships observed can be drawn.TRIAL REGISTRATION: ClinicalTrials.gov: NCT02150603. Registered 30 May 2014.

Tidskriftsartikel (refereegranskat)abstract
- This data article includes a qualitative and quantitative description of the gelatinous macrozooplankton community of the North Sea during January-February 2021. Sampling was conducted during the 1 st quarter International Bottom Trawl Survey (IBTS) on board the Danish R/V DANA (DTU Aqua Denmark) and the Swedish R/V Svea (SLU Sweden), as part of the ichthyoplankton investigation during night-time. A total of 147 stations were investigated in the western, central and eastern North Sea as well as the Skagerrak and Kattegat. Sampling was conducted with a 13 m long Midwater Ring Net (MIK net, O 2 m, mesh size 1.6 mm, cod end with smaller mesh size of 500 mu m), equipped with a flow meter. The MIK net was deployed in double oblique hauls from the surface to c. 5 m above the sea floor [1 , 2] . Samples were visually analysed unpreserved on a light table and/or with a stereomicroscope or magnifying lamp within 2 hours after catch. A total of 13,510 individuals were counted/sized. Twelve gelatinous macrozooplankton species or genera were encountered, namely the hydrozoan Aequorea vitrina, Aglantha digitale, Clytia spp., Leuckartiara octona, Tima bairdii, Muggiaea atlantica ; the scyphozoans Cyanea capillata and Cyanea lamarckii and the ctenophores Beroe spp., Bolinopsis infundibulum, Mnemiopsis leidyi, Pleurobrachia pileus . Abundance data are presented on a volume specific (m -3 ) and area specific (m -2 ) basis. Size data have been used to estimate wet weights based on published length-weight regressions (see Table 1). For the groups i) hydrozoan jellyfish, ii) scyphozoan jellyfish, iii) ctenophores, as well as iv) grouped gelatinous macrozooplankton, spatial weight specific distribution patterns are presented. This unpublished dataset contributes baseline information about the gelatinous macrozooplankton diversity and its specific distribution patterns in the extended North Sea area during winter (January-February) 2021. These data can be an important contribution to address global change impacts on marine systems, especially considering gelatinous macrozooplankton abundance changes in relation to anthropogenic stressors.(c) 2022 The Author(s).
