(författare) Keeping pace with forestry : Multi-scale conservation in a changing production forest matrix 2020 Ingår i: Ambio. - : Springer. - 0044-7447 .- 1654-7209. ; 49:5, s. 1050-1064 Tidskriftsartikel (refereegranskat)abstract The multi-scale approach to conserving forest biodiversity has been used in Sweden since the 1980s, a period defined by increased reserve area and conservation actions within production forests. However, two thousand forest-associated species remain on Sweden's red-list, and Sweden's 2020 goals for sustainable forests are not being met. We argue that ongoing changes in the production forest matrix require more consideration, and that multi-scale conservation must be adapted to, and integrated with, production forest development. To make this case, we summarize trends in habitat provision by Sweden's protected and production forests, and the variety of ways silviculture can affect biodiversity. We discuss how different forestry trajectories affect the type and extent of conservation approaches needed to secure biodiversity, and suggest leverage points for aiding the adoption of diversified silviculture. Sweden's long-term experience with multi-scale conservation and intensive forestry provides insights for other countries trying to conserve species within production landscapes.

The electron spin relaxation time may be a key factor for the performance of new CAs, such as nanosized Gd2O3 particles. The aim of this work is, therefore, to study changes in the magnetic susceptibility and the electron spin relaxation time of paramagnetic Gd2O3 nanoparticles diluted with increasing amounts of diamagnetic Y2O3. Nanoparticles of (GdxY1-x)(2)O-3 (0 <= x <= 1) were prepared by the combustion method and thoroughly characterized (by X-ray diffraction, transmission electron microscopy, thermogravimetry coupled with mass spectroscopy, photoelectron spectroscopy, Fourier transform infrared spectroscopy, and magnetic susceptibility measurements). Changes in the electron spin relaxation time were estimated by observations of the signal line width in electron paramagnetic resonance spectroscopy, and it was found that the line width was dependent on the concentration of yttrium, indicating that diamagnetic Y2O3 may increase the electron spin relaxation time of Gd2O3 nanoparticles.

(författare) Cortisol levels and psychosocial factors in preadolescent children 2006 Ingår i: Stress and Health. - : Wiley. - 1532-3005 .- 1532-2998. ; 22:1, s. 3-9 Tidskriftsartikel (refereegranskat)abstract Regarding the relationship between psychosocial factors and health, one model of explanation states that psychosocial stress constitutes a principal mediator connecting psychosocial factors to health outcome, affecting the body through psychobiological mechanisms. This relationship has scarcely been studied in children. In the present study the relation between diurnal cortisol secretion and psychosocial factors [socio-economic status (SES), immigrant status and impact of psychiatric symptoms] was investigated in a normal population of 6-12 year old children (n = 273). Salivary cortisol levels were measured in the early morning, late morning and in the evening during three consecutive days. Parents answered demographic questionnaires and teachers answered psychiatric questionnaires concerning the children. Children exposed to one or more of the factors of psychosocial load (n = 117) had significantly higher morning (p < 0.001) and evening (p = 0.029) cortisol levels as well as total daily cortisol secretion [measured by the area under the curve (AUC), p = 0.003] compared to the group of children with none of the factors (n = 156). Different psychosocial stressors seemed to influence different parts of the diurnal cortisol curve. In conclusion, this study indicates that even children exposed to a moderate degree of psychosocial load differ in their cortisol levels compared to non-exposed children.

Karger AG. - 0302-282X .- 1423-0224. ; 57:1-2, s. 14-21 Tidskriftsartikel (refereegranskat)abstract <i>Background/Aims:</i> Recent results indicate a role of the hypothalamic-pituitary-adrenal (HPA) axis in the pathophysiology of obsessive-compulsive disorder (OCD). Although childhood onset is common, the HPA axis has scarcely been studied in young OCD subjects. Therefore, the present study aimed at examining basal and response levels of salivary cortisol in a sample of young OCD subjects. <i>Methods:</i> Twenty-three children and adolescents with DSM-IV OCD were compared to a reference group of school children (n = 240–336). The basal cortisol rhythm was measured through saliva samples 3 times/day. The cortisol response to a psychological stressor (exposure therapy in the OCD group and a fire alarm in the reference group) was also examined. <i>Results:</i> Compared to the reference group, OCD subjects displayed higher early-morning cortisol values (p = 0.005) with no difference between the late-morning and evening values. The cortisol levels in the OCD group diminished in response to the psychological stressor, compared to a positive response in the reference group (p < 0.001). No relation was found between cortisol and clinical parameters. <i>Conclusion:</i> These results support the idea that HPA hyperactivity, commonly found in adult OCD patients, is also present at an earlier stage of development, with specificity for the early-morning peak.

(författare) Diurnal cortisol levels, psychiatric symptoms and sense of coherence in abused adolescents. 2010 Ingår i: Nordic Journal of Psychiatry. - : Informa UK Limited. - 0803-9488 .- 1502-4725. ; 64:1, s. 27-31 Tidskriftsartikel (refereegranskat)abstract Background. The role of the hypothalamic-pituitary-adrenal (HPA) axis in psychiatric disorders following trauma is poorly studied and most studies have been done on adults. Aims. To investigate the association of mental well-being and diurnal cortisol in abused adolescents. Methods. The present cross-sectional study examined diurnal salivary cortisol (measured three times a day during three days) in relation to psychiatric symptoms (Trauma Symptoms Checklist for Children) and the salutogenic construct “sense of coherence”, in 15 adolescents exposed to childhood abuse. Results. Significant correlations were found between symptoms and sense of coherence versus early and late morning cortisol concentrations. The correlations were most consistent for internalizing and externalizing symptoms, and somewhat less for post-traumatic symptoms and sense of coherence. In contrast, evening cortisol did not correlate with any of the psychological measures. Conclusion. These results extend previous research findings by pointing towards a relation between symptoms and higher morning cortisol and accentuated diurnal cortisol variation in abused adolescent as opposed to lower basal cortisol and a flattening of the cortisol rhythm repeatedly observed in traumatized adults. Clinical implications. The pathophysiology of the impact of trauma on youth, including the impact on biological stress systems, are important for an understanding of the consequences of trauma and may serve as a basis for the development of new treatment options.
7.	Gustafsson, Per E, et al. (författare) Does quantity have a quality all its own? Cumulative adversity and up- and down-regulation of circadian salivary cortisol levels in healthy children. 2010 Ingår i: Psychoneuroendocrinology. - : Elsevier. - 0306-4530 .- 1873-3360. ; 35:9, s. 1410-1415 Tidskriftsartikel (refereegranskat)abstract Findings have been divergent regarding the direction of basal cortisol dysregulations resulting from stressor exposure, and seem to differ between young people and adults. Accumulated stress exposure has been suggested to be a risk factor for the development of hypocortisolism. This cross-sectional study aims to examine the impact of cumulative adversity, i.e., the number of adversities, on diurnal salivary cortisol levels, including the cortisol awakening response (CAR), in children without psychiatric disorder. The sample consisted of 130 children (mean age 12.8 years), representing one in each twin pair included in the population-based Child and Adolescent Twin Study in Sweden (CATSS). Information about socioeconomic disadvantage, negative life events and potentially traumatic life events were collected by telephone interview and questionnaires, with parents as informants. Salivary cortisol sampling was performed in the home during two school days: at awakening, +30 min post-awakening, and at bedtime. Results showed that the number of adversities was related to the CAR, diurnal decline and +30 min post-awakening cortisol levels. Children with a moderate amount of cumulative adversity displayed high cortisol measures, while those with a high amount (3 or more) of adversities instead showed levels similar to the non-exposed group, yielding an inverse U-pattern of the association between cortisol and adversity. These results indicate that the accumulation of adversity might be an explanation of patterns of basal cortisol up-regulation in children and that those most severely exposed can exhibit an early stage of down-regulation, an issue which should be further examined in longitudinal studies.
8.	Gustafsson, Per E, et al. (författare) Effects of an outdoor education intervention on the mental health of schoolchildren 2012 Ingår i: Journal of Adventure Education and Outdoor Learning. - : Routledge. - 1472-9679 .- 1754-0402. ; 12:1, s. 63-79 Tidskriftsartikel (refereegranskat)abstract This study aimed at examining the effects of an outdoor educational intervention on the mental health of schoolchildren. Two elementary schools participated (N = 230); one experimental school where the intervention was implemented, and the other a reference school. Demographic questions and the Strengths and Difficulties Questionnaire were completed by the parents. An outdoor educational intervention was implemented at the experimental school, and the data collection was repeated after one year. The results point towards a small but non-significant improvement in mental health at the experimental school while adjusting for demographics. However, this effect was significantly moderated by gender: boys generally fared better than girls at the intervention school, relative to the reference school. The results indicate that it may be important to address gender issues when educational programmes are implemented in schools.
9.	Gustafsson, Per E, 1981- (författare) Psychosocial Stress, Mental Health and Salivary Cortisol in Children and Adolescents 2008 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Stressful experiences and conditions in childhood influence the health and well-being of the growing individual, and can also confer a long-lasting impact into adult life. Delineating the social, mental and biological aspects of stress in children and adolescents is therefore of great concern for human beings. Despite these notions, much knowledge is lacking regarding stress in childhood.This thesis aimed at examining diverse aspects of stress in children and adolescents: associations between social conditions, traumatic life events, mental health, and salivary cortisol as a measure of the activity of a major physiological stress system. Cross-sectional samples included two non-clinical samples of school-aged children (N=240-336) and adolescents (N =400), and two clinical samples of children with obsessive-compulsive disorder (OCD) (N =23) and adolescents who had experienced childhood abuse (N =15). Main measures were salivary cortisol sampled three times a day, and questionnaires to teachers, parents and children with questions about each child’s mental health, traumatic life events and about the socioeconomic situation of the parents.The main findings include observation of 1) higher cortisol levels in children with a moderate level of psychosocial burden (low socioeconomic status, immigrant family, social impairment of mental health problems), 2) higher cortisol levels in children with OCD who also displayed a tendency to decreasing cortisol in the face of an acute stressor, and 3) cortisol was positively related to mental health problems in abused adolescents. Furthermore, the deleterious effect of 4) traumatic events involving a social dimension, interpersonal traumas, and 5) cumulative traumatic events, polytraumatization, on the mental health of children and adolescents was indicated.The findings are discussed with respect to the complex interactions between social, mental and biological aspects of children and adolescents. The consequences of adverse experiences in childhood may represent pathways to future health problems. Consideration of the social circumstances in childhood might in the future guide public health policies and the identification of target groups for preventive interventions as well as leading to improvements in treatment for children exposed to severe stress.

This cross-sectional study examined the differential relationships between life-time exposure to interpersonal and non-interpersonal traumatic life events as well as sociocultural factors (family social class and immigrant family), and the level of externalizing versus internalizing symptoms. Participants included 258 children aged 6 to 12 years from two Swedish elementary schools. Information was obtained from their parents by means of questionnaires (a demographic form including information about parental occupation and country of origin, the Strengths and Difficulties Questionnaire and the Life Incidence of Traumatic Events checklist). While controlling for gender, age and the other symptom dimension, the sociocultural factors were associated to internalizing but not to externalizing symptoms. In contrast, traumatic life events and especially interpersonal traumas related to externalizing symptoms but not to internalizing symptoms. These findings provide some support for specificity of psychosocial adversities and for the importance of interpersonal traumas, in the impact on child mental health.

Here we show that this resemblance is more than skin deep. We apply a multidisciplinary experimental approach to characterize the cellular and molecular composition of integumental tissues in an exceptionally preserved specimen of the Early Jurassic ichthyosaur Stenopterygius. Our analyses recovered still-flexible remnants of the original scaleless skin, which comprises morphologically distinct epidermal and dermal layers. These are underlain by insulating blubber that would have augmented streamlining, buoyancy and homeothermy. Additionally, we identify endogenous proteinaceous and lipid constituents, together with keratinocytes and branched melanophores that contain eumelanin pigment. Distributional variation of melanophores across the body suggests countershading, possibly enhanced by physiological adjustments of colour to enable photoprotection, concealment and/or thermoregulation. Convergence of ichthyosaurs with extant marine amniotes thus extends to the ultrastructural and molecular levels, reflecting the omnipresent constraints of their shared adaptation to pelagic life.

However, little is known about cortisol levels in healthy children. The aim of this study was to examine cortisol levels in relation to body mass index (BMI), age and sex. METHODS: Salivary samples were collected in early morning, late morning and evening, on four consecutive days, from 342 children aged 6-12years using Salivette((R)) tubes. Samples were analysed using a commercial enzyme immunoassay (EIA). School nurses measured the children's height and weight, and these measurements were used to calculate their BMI. RESULTS: The children displayed a circadian rhythm in cortisol secretion, with morning zeniths and evening nadirs. Average cortisol levels in early morning, late morning and evening were significantly lower in overweight and obese children than in their normal weight counterparts. Cortisol levels did not vary significantly with age or sex. CONCLUSION: Our findings may suggest cortisol suppression in overweight and obese children. We found no evidence that sex or age influences cortisol levels. These findings highlight the need for further research on the relationship between stress and obesity in children.

In the present study, we demonstrate a role for MTHFD2 in DNA replication and genomic stability in cancer cells, and perform a drug screen to identify potent and selective nanomolar MTHFD2 inhibitors; protein cocrystal structures demonstrated binding to the active site of MTHFD2 and target engagement. MTHFD2 inhibitors reduced replication fork speed and induced replication stress followed by S-phase arrest and apoptosis of acute myeloid leukemia cells in vitro and in vivo, with a therapeutic window spanning four orders of magnitude compared with nontumorigenic cells. Mechanistically, MTHFD2 inhibitors prevented thymidine production leading to misincorporation of uracil into DNA and replication stress. Overall, these results demonstrate a functional link between MTHFD2-dependent cancer metabolism and replication stress that can be exploited therapeutically with this new class of inhibitors. Helleday and colleagues describe a nanomolar MTHFD2 inhibitor that causes replication stress and DNA damage accumulation in cancer cells via thymidine depletion, demonstrating a potential therapeutic strategy in AML tumors in vivo.

The dose of MPH for good symptom control differs between patients. However, studies of MPH concentration measurement in ADHD treatment are limited.OBJECTIVE: To describe blood and oral fluid (OF) concentrations of MPH after administration of medication in patients with well-adjusted MPH treatment for ADHD, and to identify the most suitable matrix for accurate MPH concentration during treatment.METHODS: Patients were recruited from Child and Adolescent Psychiatry (CAP), General Psychiatry (GP), and the Department of Dependency (DD). Blood and OF samples were collected in the morning before MPH administration as well as 1 and 6 h after administration of the prescribed morning dose of MPH.RESULTS: Fifty-nine patients aged between 9 and 69 years, 76 % males. The daily dose of MPH varied from 18 to 180 mg, but the median daily dose per body weight was similar, approximately 1.0 mg/kg body weight. The median MPH concentration in blood 1 and 6 h after the morning dose was 5.4 and 9.3 ng/mL, respectively. Highly variable OF-to-blood ratios for MPH were found at all time points for all three groups.CONCLUSIONS: Weight is a reliable clinical parameter for optimal dose titration. Otherwise, MPH blood concentration might be used for individual dose optimization and for monitoring of the prescribed dose. Relying only on the outcome in OF cannot be recommended for evaluation of accurate MPH concentrations for treatment monitoring.

When analyzing cardiovascular risk factors, 3,594 individuals from the population-based survey in Northern Sweden, MONICA (MONItoring of Trends and Determinants of CArdiovascular Disease), served as controls.MAIN OUTCOME MEASURE: Prevalence of autoimmune comorbidities and cardiovascular risk factors. Autoantibodies against 13 autoantigens were determined.RESULTS: Sixty percent of the SAR cohort consisted of females. Mean age at diagnosis was significantly higher for females than for males (36.8 vs. 31.1 years). The proportion of 21-hydroxylase autoantibody positive patients was 83% and 62% of patients had one or more associated autoimmune diseases, more frequently coexisting in females (p<0.0001). AAD patients had lower BMI (p<0.0001) and prevalence of hypertension (p=0.027) compared with controls. Conventional hydrocortisone tablets were used by 89% of patients; with the mean dose 28.1±8.5 mg/day. The mean hydrocortisone equivalent dose normalized to body surface was 14.8±4.4 mg/m(2)/day. Higher hydrocortisone equivalent dose was associated with higher incidence of hypertension (p=0.046).CONCLUSIONS: Careful monitoring of AAD patients is warranted to detect associated autoimmune diseases. Contemporary Swedish AAD patients do not have increased prevalence of overweight, hypertension, T2DM or hyperlipidemia. However, high glucocorticoid replacement doses may be a risk factor for hypertension.

(författare) Tidig upptäckt - tidig insats (TUTI) : slutrapport 2015 Rapport (övrigt vetenskapligt/konstnärligt)abstract Ur sammanfattningen: Små barns psykiska hälsa har de senaste åren uppmärksammats mer än tidigare. De insatser som görs för att stärka hälsa hos små barn har visat sig ge goda effekter på barns psykiska hälsa senare i livet. Förskolan har lyfts fram både som en miljö i vilken barns psykiska ohälsa tidigt kan upptäckas men också som en miljö som genom tidiga insatser kan främja god psykisk hälsa och ge skydd mot ohälsa. Angående små barn i Sverige saknas en samlad kunskap om väl validerade instrument för att mäta psykisk ohälsa hos små barn, förekomsten av psykisk ohälsa och även om de åtgärder som görs i förskolan för att skydda mot senare negativ utveckling av psykisk hälsa hos barnen. Uppdraget från Socialstyrelsen handlar om att validera ett instrument för att mäta beteendeproblem hos små barn och att kartlägga förekomsten av beteendeproblem hos små barn. Även åtgärder som utförs i förskolan för gruppen kartläggs. Fokus ligger alltså på tidig upptäckt och tidig insats (TUTI) när det gäller små barn som uppvisar beteendeproblem i förskolan.

Few studies have investigatedsuch orchestrated effects on mental health in young children over time. The aims of the study are rst, to identify homogeneous groups of children havingsimilar pathways in mental health between three time points. Second, to examine how children move between time points in relation to risk and protectivefactors. Alongitudinal study over 3 years, including 197 Swedish preschool children was used. Questionnaire data collected from preschool teachers.Statistical analysis using person-oriented methods with repeated cluster analyses. Children high in engagement/social skills and low in conduct problemscontinue to function well. Children with low engagement/social skills exhibiting both hyperactivity and conduct problems continue to have problems.Children with mixed patterns of protective factors and risk factors showed mixed outcomes. The stability of children’s pathways was quite high if theyexhibited many positive protective factors but also if they exhibited many risk factors. Children exhibiting a mixed pattern of protective and risk factorsmoved between clusters in a less predictable way. That stability in mental health was related to the simultaneous occurrence of either many protectivefactors or many risk factors supports the notion of orchestrated effects. The results indicate that early interventions need to have a dual focus, includingboth interventions aimed at enhancing child engagement and interventions focused on decreasing behavior problem.
25.	Gustafsson, Berit M., et al. (författare) Emotional and behavioural problems in Swedish preschool children rated by preschool teachers with the Strengths and Difficulties Questionnaire (SDQ) 2017 Ingår i: BMC Pediatrics. - : BioMed Central. - 1471-2431. ; 17:1 Tidskriftsartikel (refereegranskat)abstract Background: There is a high risk that young children who show early signs of mental health problems develop symptoms in the same or overlapping areas some years later. The Strengths and Difficulties Questionnaire (SDQ) is widely used to screen externalizing and internalizing problems early in life. In Sweden 80-90% of all children aged 1-5 years go to preschool and preschool is thus an appropriate context for finding early signs of mental health problems among children.Methods: This study is part of a longitudinal project too investigate the frequency of emotional and behavioural problems for children between 1 and 5 years of age in Sweden. The SDQ including the impairment supplement questions were rated by preschool teachers too establish Swedish norms for SDQ in preschool children.Results: The sample involved 815 children with a mean age of 42 months (SD = 16, range 13-71 months). 195 children were followed longitudinally for three years. There were significant differences between boys and girls on all subscales except for the Emotional subscale. The prevalence of behavioural problems was similar to other that in European countries, except for Prosocial behaviour, which was rated lower, and Conduct problems, rated higher. Swedish children were estimated to have more problems in the preschool setting, scored by preschool teachers. The development of behaviour over time differed for the different subscales of SDQ.Conclusions: The teacher version of the SDQ, for 2-4 year-olds, can be used as a screening instrument to identify early signs of emotional distress/behavioural problems in young children. Preschool teachers seem to be able to identify children with problematic behaviour with the use of SDQ at an early age. The development of behaviour over time differs for the different subscales of SDQ. The Swedish norms for SDQ are to a large extent, similar to findings from other European countries.

Latent growth modelling of conduct problems was carried out, with gender and hyperactivity at year 1 as time-invariant predictors.Results: Hyperactivity was a significant predictor for the intercept and slope of conduct problems. Children with more hyperactivity at year 1 had more conduct problems and a slower reduction in conduct problems. Gender was a significant predictor for the slope of conduct problems.Conclusions: Children with more initial hyperactivity have less of a reduction in conduct problems over time. It is important to consider the role of hyperactivity in studies of the development of conduct problems.Declaration of interest: None.
27.	Gustafsson, Berit M., 1966- (författare) Identifying Patterns of Emotional and Behavioural Problems in Preschool children : Facilitating Early Detection 2018 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Mental health problems often debut in early childhood and may last throughout adulthood, thereby making early detection and intervention especially important. The overarching aim of the present thesis was to identify patterns of emotional and behavioural problems indicating mental health problems in preschool children. To facilitate the detection of such problems early on, one available screening instrument Strengths and Difficulties Questionnaire (SDQ), was validated. The development and interaction of externalising problems in preschool children were studied over time. Functioning and behaviour and their relations to protective and risk indicators in both environmental and personal characteristics were explored. The long-term goal was to increase knowledge about early identification of emotional and behavioural problems in preschool children in order to facilitate early intervention.In Study I (n=690), the subscales Hyperactivity and Conduct Problems were shown to be valid for children in the age group 1–3 years. A reasonable level of validity was found for the age group 4–5 years when using the original SDQ four-factor solution. The preschool teachers considered most of the SDQ items relevant and possible to rate. Based on the results of Study II (n=815), a score of ≥12 on the SDQ Total Problems Scale is recommended as a cut-off for Swedish preschool children. There were significant differences between boys and girls on all subscales except for the Emotional subscale. The Swedish norms for SDQ are to a large extent similar to findings from other European countries. Study III (n=195) showed that preschool children’s conduct problems decrease over time. Children exhibiting more initial hyperactivity (at year 1) have less reduction in conduct problems over time, i.e. the more hyperactivity early in life, the more conduct problems at year 3. In Study IV (n=197), children high in engagement and social interaction function well over time, even in the presence of hyperactivity, while children with low engagement and interaction alone or in combination with hyperactivity and conduct problems continue to have problems. Stability was related to the existence of a larger number of protective or risk indicators respectively.Taken together, this thesis has shown that the SDQ can be used to identify preschool children at risk of developing mental health problems later in life.

(författare) The strengths and difficulties questionnaire (SDQ) for preschool children : a Swedish validation 2016 Ingår i: Nordic Journal of Psychiatry. - : Informa UK Limited. - 0803-9488 .- 1502-4725. ; 70:8, s. 567-574 Tidskriftsartikel (refereegranskat)abstract Background: In Sweden, 80–90% of children aged 1–5 years attend preschool, and that environment is well suited to identify behaviours that may be signs of mental health problems. The Strengths and Difficulties Questionnaire (SDQ) is a well-known short and structured instrument measuring child behaviours that indicate mental health problems well suited for preschool use.Aim: To investigate whether SDQ is a reliable and valid instrument for identifying behavioural problems in children aged 1–3 years and 4–5 years in a Swedish population, as rated by preschool teachers.Methods: Preschools situated in different sized municipalities in Sweden participated. The preschool teacher rated each individual child. Concurrent validity was tested using the Child–Teacher Report Form (C-TRF) and Child Engagement Questionnaire (CEQ). Exploratory factor analysis was conducted for age groups, 1–3 years and 4–5 years.Results: The preschool teachers considered most of the SDQ items relevant and possible to rate. For the children aged 1–3 years, the subscales ‘Hyperactivity’ (Cronbach alpha = 0.84, split half = 0.73) and ‘Conduct’ (Cronbach alpha = 0.76, split half = 0.80) were considered to be valid. For the age group 4–5 years, the whole original SDQ scale, 4-factor solution was used and showed reasonable validity (Cronbach alpha = 0.83, split half = 0.87).Conclusion: SDQ can be used in a preschool setting by preschool teachers as a valid instrument for identifying externalizing behavioural problems (hyperactivity and conduct problems) in young children.Clinical implications: SDQ could be used to identify preschool children at high-risk for mental health problems later in life.

(författare) School, Learning and Mental Health : A systematic review 2010 Rapport (övrigt vetenskapligt/konstnärligt)abstract Rapporten presenterar resultaten från en systematisk översikt av forskning om skola, lärande och barns psykiska hälsa. Kungliga Vetenskapsakademiens Hälsoutskottet har givit uppdraget att genomföra en sådan översikt till en arbetsgrupp som har arbetat med uppdraget från hösten 2008 till mars 2009. Det första syftet med översikten är att genomföra en kartläggning av forskning inom det breda fält som behandlar frågor om skola, lärande och barns och ungdomars psykiska hälsa. Det andra syftet är att genomföra en narrativ syntes av forskning som undersökt orsaksförhållanden mellan psykisk hälsa å ena sidan och skolresultat och lärande å den andra sidan. Det tredje syftet är att redovisa resultat från forskning som har studerat svenska barns och ungdomars erfarenheter och upplevelser av skola och undervisningssituationer. För att uppnå de första två syftena genomfördes systematiska litteratursökningar i bibliografiska databaser av artiklar publicerade i vetenskapliga internationella tidskrifter inom olika discipliner. Det tredje syftet undersöktes med litteratursökningar av kvalitativa svenska studier i bibliografiska databaser. Slutsatser På grundval dels av kartläggningen av forskning om skola, lärande och psykisk hälsa, dels av de två fördjupade översikterna kan följande slutsatser dras: • Omfattningen av forskning som undersöker relationerna mellan olika aspekter av skola och psykisk hälsa är begränsad och i synnerhet gäller detta forskning som undersöker organisationsfaktorer och undervisnings-faktorer, aktiviteter, läroplaners utformning, resurser, specialpedagogiskt stöd, och olika former av betyg och bedömning. • Tidiga svårigheter i skolan och i synnerhet läs- och skrivsvårigheter kan orsaka internaliserande och externaliserande psykiska problem. • Svårigheter i skola och psykiska problem tenderar att vara stabila över tid. • Skolrelaterade hälsoproblem tenderar att minska när eleverna börjar på gymnasiet och får tillgång till nya områden av aktiviteter, roller och valmöjligheter. • Att genomföra stora ansträngningar utan att detta leder till resultat är relaterat till utveckling av depression. Problem i skolan med skolresultat och prestationer orsakar inter-naliserande symptom för flickor under tonåren. • Det finns samband mellan olika typer av psykiska problem och de är också relaterade till ett brett spektrum av somatiska och psykosomatiska symptom. • Internaliserande och externaliserande psykiska problem har negativa effekter på skolprestationer genom mekanismer som är delvis ålders- och genusspecifika. • Kompetenser och prestationer i skolan är relaterade till psykisk hälsa. • Goda resultat i skolan har en positiv effekt på självuppfattning. • En god självuppfattning bidrar inte direkt till bättre resultat, men andra faktorer som är relaterade till självuppfattning (motivation och upplevd inre/yttre kontroll) påverkar lärande och resultat • Relationer med klasskamrater och lärare bidrar till processer som kopplar skolmisslyckande till psykisk ohälsa. Relationer med kamrater och lärare kan också skydda mot utvecklingen av psykiska problem. • Jämförelser med klasskamrater påverkar självuppfattningen, med effekter som varierar beroende på gruppsammansättning och typ av skola.

Liver transplantation (LTx) is an accepted treatment for hereditary transthyretin (TTR) amyloidosis (ATTR). However, unforeseen heart complications, especially a rapid development of cardiomyopathy after LTx has affected mortality and morbidity. Recently, a relationship between ATTR-fibril composition and cardiomyopathy has been noted. The aim of this study was to investigate whether development of cardiomyopathy and heart failure in LTx ATTR amyloid patients is related to amyloid fibril composition.Methods. Twenty-four patients with hereditary ATTR amyloidosis who had undergone LTx and have had their amyloid fibril type tested were available for the study. They had been examined by echocardiography including tissue Doppler and speckle tracking echocardiography before and after LTx. Patients were divided into two groups according to fibril composition, 10 patients with type A fibrils (a mixture of truncated and full-length TTR) and 14 patients with type B fibrils (full-length TTR fibrils only). There was no difference in time to the follow-up echocardiography between the two groups.Results. After LTx, the group consisting of type A patients developed symptoms of heart failure and with reduced systolic and diastolic ventricular function as shown by echocardiography, whereas no similar deterioration was noted for the group of patients with type B fibrils.Conclusion. Patients with type A fibrils deteriorate an already existing cardiomyopathy and heart failure after LTx, in contrast to patients with type B fibrils. These results might have significant clinical implications in optimizing best patients selection criteria for LTx.

During the dynamic springflood conditions studied, small 238U-234Th disequilibria, low sediment trap fluxes, laboratory mixing experiments, as well as results from an independent two-box, two-dimensional mixing model combine to suggest that no significant removal of Fe, Si, or organic C was occurring in the highly-resolved LSZ. While no conclusions may be drawn based solely on property-salinity plots over narrow salinity ranges, apparently linear graphs for Fe and Si over 3 separate years also suggest minimal removal in this regime. At the same time, size distributions both of elements -from cross-flow ultrafiltration - and of bulk suspended solids - from light scattering (photon correlation spectroscopy [PCS]) - indicated that significant aggregation was taking place.The aggregation-without-significant-settling scenario in this low-salinity mixing regime, with a geochemistry similar to that of neighboring Russian Arctic rivers, is hypothesized to result from a comparatively high organic-to-detrital matter characteristic of the aggregates. While first principles would indeed suggest that decreasing electrostatic repulsion during mixing lead to aggregation, a low specific density of mineral-poor amorphous organic aggregates may lead to transport of these authigenic particles further away from the river mouth. The role of detrital "sinkers" on vertical removal of suspended organic matter is discussed in the wider context of scavenging mechanisms in the ocean.

This study was designed to evaluate the vitamin D status and circulating bone metabolic markers and their determinants in children at the time of diagnostic evaluation for hemato-oncological disease. This cross-sectional study included 165 children (91 males, median age 6.9 yr range 0.2-17.7 yr). Of them, 76 patients were diagnosed with extracranial or intracranial solid tumors, 83 with leukemia, and 6 with bone marrow failure. Bone metabolism was assessed by measuring serum 25OHD, PTH, bone alkaline phosphatase, intact N-terminal propeptide of type I procollagen, and C-terminal cross-linked telopeptide of type I collagen. Vitamin D deficiency was found in 30.9% of children. Lower 25OHD levels were associated with older age, lack of vitamin D supplementation, season outside summer, and a country of parental origin located between latitudes -45 degrees and 45 degrees. Children diagnosed with leukemia had lower levels of markers of bone formation and bone resorption than those who had solid tumors or bone marrow failure. In conclusion, vitamin D deficiency was observed in one-third of children with newly diagnosed cancer. Bone turnover markers were decreased in children with leukemia, possibly because of the suppression of osteoblasts and osteoclasts by leukemic cells. The identification of patients with suboptimal vitamin D status and compromised bone remodeling at cancer diagnosis may aid in the development of supportive treatment to reduce the adverse effects of cancer and its treatment.

40.	Karlsson, Per Erik, et al. (författare) Kartläggning av inhemska biogena koldioxidutsläpp i Sverige 2023 Rapport (övrigt vetenskapligt/konstnärligt)abstract I denna studie har kartlagts hur mycket av de biogena utsläppen i Sveriges inventering av växthusgasutsläpp, som rapporteras till EU och UNFCCC, som härrör från inhemsk produktion av biomassa och hur mycket som är importerad råvara. Ett viktigt syfte har varit att belysa i vad mån storleken på de biogena utsläppen från förbränning av biomassa inom energisektorn som redovisas under ’memo items’ CO2 emissions from biomass överensstämmer med storleken på den del av de rapporterade balanserna för förändringar i kolförråden levande och död biomassa som redovisas i sektorn markanvändning och skogsbruk, LULUCF, som kan förknippas med de biogena utsläppen.Rapporten innehåller en djupgående beskrivning av de metoder som idagsläget används för beräkningar av CO2 emissions from biomass, redovisade under ’memo items’ och de metoder som används i beräkningarna av nettoupptag i LULUCF-sektorn där de biogena utsläppen ingår.Den officiella redovisningen av LULUCF-sektorn är en nettoberäkning av kolförrådsförändringar inom Sverige som inkluderar (men inte särredovisar) upptag och avgång av koldioxid. Därför har en kartläggning gjorts av biomassaflöden i Sverige, inklusive export och import, för att möjliggöra en skattning av utsläppen av biogen koldioxid i LULUCF-sektorn och i vilken utsträckning dessa kan förknippas med utsläpp från energiproduktion från biogent bränsle i Sverige.Tillförseln av skogsråvaror från import och från inhemskt skogsbruk till industrin, inklusive rundved, avverkningsrester samt brännved och annat som används direkt av hushållen, motsvarade nästan 70 miljoner ton koldioxid varav ca 6 miljoner ton härrör från import. Ungefär hälften av rundvirket som tas ut från skogen blir pappersmassa och träprodukter. Resten (brännved, flis, spån, bark, svartlut) används främst till energiframställning och motsvarar ca 32 miljoner ton koldioxid. Utöver rundvirket tas avverkningsrester (grenar och toppar från skogsbruket) tillvara för energiproduktion motsvarande ca 3,5 miljoner ton koldioxid. Tillsammans med den avgång som sker från slutanvända trä- och pappersprodukter skattas den årliga avgången för år 2019 av koldioxid från svensk skogsråvara i LULUCF-sektorn till ca 39 miljoner ton.En genomgång och kvantifiering av flöden och ursprung (inhemsk produktion och import) av den biomassa som utgör biobränsle i Sverige och som ingår i emissionsberäkningarna för CO2 emissions from biomass i energisektorn visade att bränslet kan fördelas mellan 12 olika kategorier. Den största posten av biogena utsläpp med ursprung i svensk skog kommer från förbränning av svartlut och träbränslen. Tillsammans utgör svartlut och träbränslen 74 % av alla biogena utsläpp. Av de totala biogena utsläppen (53 miljoner ton koldioxid) har utsläpp från importerat biobränsle (framförallt FAME, avfall och svartlut) skattats till totalt 20 % för 2021. Det innebär att ca 80 % (41 miljoner ton koldioxid) av utsläppen som redovisas under CO2 emissions from biomass har sitt ursprung i inhemsk produktion av skogsråvara och därmed borde motsvara en betydande del av avgången av koldioxid i nettoberäkningen av kolförrådsförändringarna i levande och död biomassa som beräknas inom LULUCF-sektorn och som kan förknippas med de biogena utsläppen.Den övergripande kartläggningen av flöden av inhemskt biogent producerad råvara och produkter från denna råvara i jämförelse med biobränsleanvändning i Sverige visar att skattningarna av utsläpp är storleksmässig jämförbara (39 respektive 41 miljoner ton koldioxid). Detta trots att det finns kända skillnader i de statistiska underlagen och den tidsmässiga representativiteten.Resultaten visar också hur stor del av en avverkning som blir till långlivade träprodukter och hur mycket som relativt snabbt avgår till atmosfären genom förbränning där energi tas till vara.Slutligen ges i denna rapport en översiktlig schematisk beskrivning av antropogena årliga strömmar, förbränning samt övrig nedbrytning av biogent producerad råvara, samt dess produkter inom Sveriges gränser, inklusive import och export.

In order to study the effect of groundwater level and soil temperature on C-flux, the CoupModel was calibrated (climate data, groundwater levels, soil CO2 flux, net ecosystem fluxes of CO2-exchange, sensible heat flux and latent heat flux, forest production etc.) for a drained forest in Sweden. Bayesian calibration techniques were used to elucidate how different parameters and variables were interlinked in C-circulation. The calibrated model reproduced abiotic and biotic variables reasonably well except for root respiration, which was largely underestimated. Bayesian calibration reduced the uncertainties in the model and highlighted the fact that calibrations should be performed with a high number of parameters instead of specific parameter values.

We aimed to compare the efficacy and safety of neoadjuvant FOLFIRINOX with the standard strategy of upfront surgery in patients with resectable pancreatic ductal adenocarcinoma.MethodsNORPACT-1 was a multicentre, randomised, phase 2 trial done in 12 hospitals in Denmark, Finland, Norway, and Sweden. Eligible patients were aged 18 years or older, with a WHO performance status of 0 or 1, and had a resectable tumour of the pancreatic head radiologically strongly suspected to be pancreatic adenocarcinoma. Participants were randomly assigned (3:2 before October, 2018, and 1:1 after) to the neoadjuvant FOLFIRINOX group or upfront surgery group. Patients in the neoadjuvant FOLFIRINOX group received four neoadjuvant cycles of FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, and fluorouracil 400 mg/m2 bolus then 2400 mg/m2 over 46 h on day 1 of each 14-day cycle), followed by surgery and adjuvant chemotherapy. Patients in the upfront surgery group underwent surgery and then received adjuvant chemotherapy. Initially, adjuvant chemotherapy was gemcitabine plus capecitabine (gemcitabine 1000 mg/m2 over 30 min on days 1, 8, and 15 of each 28-day cycle and capecitabine 830 mg/m2 twice daily for 3 weeks with 1 week of rest in each 28-day cycle; four cycles in the neoadjuvant FOLFIRINOX group, six cycles in the upfront surgery group). A protocol amendment was subsequently made to permit use of adjuvant modified FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 150 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2 over 46 h on day 1 of each 14-day cycle; eight cycles in the neoadjuvant FOLFIRINOX group, 12 cycles in the upfront surgery group). Randomisation was performed with a computerised algorithm that stratified for each participating centre and used a concealed block size of two to six. Patients, investigators, and study team members were not masked to treatment allocation. The primary endpoint was overall survival at 18 months. Analyses were done in the intention-to-treat (ITT) and per-protocol populations. Safety was assessed in all patients who were randomly assigned and received at least one cycle of neoadjuvant or adjuvant therapy. This trial is registered with ClinicalTrials.gov, NCT02919787, and EudraCT, 2015-001635-21, and is ongoing.FindingsBetween Feb 8, 2017, and April 21, 2021, 77 patients were randomly assigned to receive neoadjuvant FOLFIRINOX and 63 to undergo upfront surgery. All patients were included in the ITT analysis. For the per-protocol analysis, 17 (22%) patients were excluded from the neoadjuvant FOLFIRINOX group (ten did not receive neoadjuvant therapy, four did not have pancreatic ductal adenocarcinoma, and three received another neoadjuvant regimen), and eight (13%) were excluded from the upfront surgery group (seven did not have pancreatic ductal adenocarcinoma and one did not undergo surgical exploration). 61 (79%) of 77 patients in the neoadjuvant FOLFIRINOX group received neoadjuvant therapy. The proportion of patients alive at 18 months by ITT was 60% (95% CI 49–71) in the neoadjuvant FOLFIRINOX group versus 73% (62–84) in the upfront surgery group (p=0·032), and median overall survival by ITT was 25·1 months (95% CI 17·2–34·9) versus 38·5 months (27·6–not reached; hazard ratio [HR] 1·52 [95% CI 1·00–2·33], log-rank p=0·050). The proportion of patients alive at 18 months in per-protocol analysis was 57% (95% CI 46–67) in the neoadjuvant FOLFIRINOX group versus 70% (55–83) in the upfront surgery group (p=0·14), and median overall survival in per-protocol population was 23·0 months (95% CI 16·2–34·9) versus 34·4 months (19·4–not reached; HR 1·46 [95% CI 0·99–2·17], log-rank p=0·058). In the safety population, 42 (58%) of 73 patients in the neoadjuvant FOLFIRINOX group and 19 (40%) of 47 patients in the upfront surgery group had at least one grade 3 or worse adverse event. 63 (82%) of 77 patients in the neoadjuvant group and 56 (89%) of 63 patients in the upfront surgery group had resection (p=0·24). One sudden death of unknown cause and one COVID-19-related death occurred after the first cycle of neoadjuvant FOLFIRINOX. Adjuvant chemotherapy was initiated in 51 (86%) of 59 patients with resected pancreatic ductal adenocarcinoma in the neoadjuvant FOLFIRINOX group and 44 (90%) of 49 patients with resected pancreatic ductal adenocarcinoma in the upfront surgery group (p=0·56). Adjuvant modified FOLFIRINOX was given to 13 (25%) patients in the neoadjuvant FOLFIRINOX group and 19 (43%) patients in the upfront surgery group. During adjuvant chemotherapy, neutropenia (11 [22%] patients in the neoadjuvant FOLFIRINOX group and five [11%] in the upfront surgery group) was the most common grade 3 or worse adverse event.InterpretationThis phase 2 trial did not show a survival benefit from neoadjuvant FOLFIRINOX in resectable pancreatic ductal adenocarcinoma compared with upfront surgery. Implementation of neoadjuvant FOLFIRINOX was challenging. Future trials on treatment sequencing in resectable pancreatic ductal adenocarcinoma should be biomarker driven.

We aimed to compare the efficacy and safety of neoadjuvant FOLFIRINOX with the standard strategy of upfront surgery in patients with resectable pancreatic ductal adenocarcinoma.Methods: NORPACT-1 was a multicentre, randomised, phase 2 trial done in 12 hospitals in Denmark, Finland, Norway, and Sweden. Eligible patients were aged 18 years or older, with a WHO performance status of 0 or 1, and had a resectable tumour of the pancreatic head radiologically strongly suspected to be pancreatic adenocarcinoma. Participants were randomly assigned (3:2 before October, 2018, and 1:1 after) to the neoadjuvant FOLFIRINOX group or upfront surgery group. Patients in the neoadjuvant FOLFIRINOX group received four neoadjuvant cycles of FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, and fluorouracil 400 mg/m2 bolus then 2400 mg/m2 over 46 h on day 1 of each 14-day cycle), followed by surgery and adjuvant chemotherapy. Patients in the upfront surgery group underwent surgery and then received adjuvant chemotherapy. Initially, adjuvant chemotherapy was gemcitabine plus capecitabine (gemcitabine 1000 mg/m2 over 30 min on days 1, 8, and 15 of each 28-day cycle and capecitabine 830 mg/m2 twice daily for 3 weeks with 1 week of rest in each 28-day cycle; four cycles in the neoadjuvant FOLFIRINOX group, six cycles in the upfront surgery group). A protocol amendment was subsequently made to permit use of adjuvant modified FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 150 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2 over 46 h on day 1 of each 14-day cycle; eight cycles in the neoadjuvant FOLFIRINOX group, 12 cycles in the upfront surgery group). Randomisation was performed with a computerised algorithm that stratified for each participating centre and used a concealed block size of two to six. Patients, investigators, and study team members were not masked to treatment allocation. The primary endpoint was overall survival at 18 months. Analyses were done in the intention-to-treat (ITT) and per-protocol populations. Safety was assessed in all patients who were randomly assigned and received at least one cycle of neoadjuvant or adjuvant therapy. This trial is registered with ClinicalTrials.gov, NCT02919787, and EudraCT, 2015-001635-21, and is ongoing.Findings: Between Feb 8, 2017, and April 21, 2021, 77 patients were randomly assigned to receive neoadjuvant FOLFIRINOX and 63 to undergo upfront surgery. All patients were included in the ITT analysis. For the per-protocol analysis, 17 (22%) patients were excluded from the neoadjuvant FOLFIRINOX group (ten did not receive neoadjuvant therapy, four did not have pancreatic ductal adenocarcinoma, and three received another neoadjuvant regimen), and eight (13%) were excluded from the upfront surgery group (seven did not have pancreatic ductal adenocarcinoma and one did not undergo surgical exploration). 61 (79%) of 77 patients in the neoadjuvant FOLFIRINOX group received neoadjuvant therapy. The proportion of patients alive at 18 months by ITT was 60% (95% CI 49–71) in the neoadjuvant FOLFIRINOX group versus 73% (62–84) in the upfront surgery group (p=0·032), and median overall survival by ITT was 25·1 months (95% CI 17·2–34·9) versus 38·5 months (27·6–not reached; hazard ratio [HR] 1·52 [95% CI 1·00–2·33], log-rank p=0·050). The proportion of patients alive at 18 months in per-protocol analysis was 57% (95% CI 46–67) in the neoadjuvant FOLFIRINOX group versus 70% (55–83) in the upfront surgery group (p=0·14), and median overall survival in per-protocol population was 23·0 months (95% CI 16·2–34·9) versus 34·4 months (19·4–not reached; HR 1·46 [95% CI 0·99–2·17], log-rank p=0·058). In the safety population, 42 (58%) of 73 patients in the neoadjuvant FOLFIRINOX group and 19 (40%) of 47 patients in the upfront surgery group had at least one grade 3 or worse adverse event. 63 (82%) of 77 patients in the neoadjuvant group and 56 (89%) of 63 patients in the upfront surgery group had resection (p=0·24). One sudden death of unknown cause and one COVID-19-related death occurred after the first cycle of neoadjuvant FOLFIRINOX. Adjuvant chemotherapy was initiated in 51 (86%) of 59 patients with resected pancreatic ductal adenocarcinoma in the neoadjuvant FOLFIRINOX group and 44 (90%) of 49 patients with resected pancreatic ductal adenocarcinoma in the upfront surgery group (p=0·56). Adjuvant modified FOLFIRINOX was given to 13 (25%) patients in the neoadjuvant FOLFIRINOX group and 19 (43%) patients in the upfront surgery group. During adjuvant chemotherapy, neutropenia (11 [22%] patients in the neoadjuvant FOLFIRINOX group and five [11%] in the upfront surgery group) was the most common grade 3 or worse adverse event.Interpretation: This phase 2 trial did not show a survival benefit from neoadjuvant FOLFIRINOX in resectable pancreatic ductal adenocarcinoma compared with upfront surgery. Implementation of neoadjuvant FOLFIRINOX was challenging. Future trials on treatment sequencing in resectable pancreatic ductal adenocarcinoma should be biomarker driven.

(författare) Genetic studies of body mass index yield new insights for obesity biology. 2015 Ingår i: Nature. - : Springer Science and Business Media LLC. - 0028-0836 .- 1476-4687. ; 518:7538, s. 197-401 Tidskriftsartikel (refereegranskat)abstract Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P < 5 × 10(-8)), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for ∼2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.

(författare) Risk Factors of Developing Long-Lasting Breast Pain After Breast Cancer Radiotherapy. 2012 Ingår i: International journal of radiation oncology, biology, physics. - : Elsevier BV. - 1879-355X .- 0360-3016. ; 83:1, s. 71-78 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Postoperative radiotherapy decreases breast cancer mortality. However, studies have revealed a long-lasting breast pain among some women after radiotherapy. The purpose of this study was to identify risk factors that contribute to breast pain after breast cancer radiotherapy. METHODS AND MATERIALS: We identified 1,027 recurrence-free women in two cohorts of Swedish women treated for breast cancer. The women had breast-conserving surgery and postoperative radiotherapy, the breast was treated to 48 Gy in 2.4-Gy fractions or to 50 Gy in 2.0-Gy fractions. Young women received a boost of up to 16 Gy. Women with more than three lymph node metastases had locoregional radiotherapy. Systemic treatments were given according to health-care guidelines. Three to 17 years after radiotherapy, we collected data using a study-specific questionnaire. We investigated the relation between breast pain and potential risk modifiers: age at treatment, time since treatment, chemotherapy, photon energy, fractionation size, boost, loco-regional radiotherapy, axillary surgery, overweight, and smoking. RESULTS: Eight hundred seventy-seven women (85%) returned the questionnaires. Among women up to 39 years of age at treatment, 23.1% had breast pain, compared with 8.7% among women older than 60 years (RR 2.66; 95% CI 1.33-5.36). Higher age at treatment (RR 0.96; 95% CI 0.94-0.98, annual decrease) and longer time since treatment (RR 0.93; 95% CI 0.88-0.98, annual decrease) were related to a lower occurrence of breast pain. Chemotherapy increased the occurrence of breast pain (RR 1.72; 95% CI 1.19-2.47). In the multivariable model only age and time since treatment were statistically significantly related to the occurrence of breast pain. We found no statistically significant relation between breast pain and the other potential risk modifiers. CONCLUSIONS: Younger women having undergone breast-conserving surgery with postoperative radiotherapy report a higher occurrence of long-lasting breast pain compared to older women. Time since treatment may decrease the occurrence of pain.

(författare) Symptoms 10-17 years after breast cancer radiotherapy data from the randomised SWEBCG91-RT trial 2010 Ingår i: Radiotherapy and Oncology. - : Elsevier BV. - 1879-0887 .- 0167-8140. ; 97:2, s. 281-287 Tidskriftsartikel (refereegranskat)abstract Background: Postoperative radiotherapy decreases the risk for local and improves overall survival in women with breast cancer. We have limited information on radiotherapy-induced symptoms 10-17 years after therapy. Material and methods: Between 1997 and 1997, women with lymph node-negative breast cancer were randomised in a Swedish multi-institutional trial to breast conserving surgery with or without postoperative radiotherapy. In 2007, 10-17 years after randomisation, the group included 422 recurrence-free women. We collected data with a study-specific questionnaire on eight pre-selected symptom groups. Results: Fox six symptom group (oedema in breast or arm, erysipelas, heart symptoms, lung symptoms, rib fractures, and decreased shoulder mobility) we found similar occurrence in both groups. Excess occurence after radiotherapy was observed for pain in the breast or in the skin, reported to occur "occasionally" by 38.1% of survivors having undergone radiotherapy and surgery versus 24.0% of those with surgery alone (absolute difference 14.1%; p = 0.004) and at least once a week by 10.3% of the radiotherapy group versus 1.7% (absolute difference 8.6%; p = 0.001). Daily life and analgesic use did not differ between the groups. Conclusion: Ten to 17 years after postoperative radiotherapy 1 in 12 women had weekly pain that could be attributed to radiotherapy. The symptoms did not significantly affect daily life and thus the reduced risk for local recurrence seems to outweight the risk for long-term symptoms for most women. (C) 2010 Elsevier Ireland Ltd.

(författare) Superficial vessel reconstruction with a multiview camera system 2016 Ingår i: Journal of Medical Imaging. - : SPIE - International Society for Optical Engineering. - 2329-4302 .- 2329-4310. ; 3:1 Tidskriftsartikel (refereegranskat)abstract We aim at reconstructing superficial vessels of the brain. Ultimately, they will serve to guide the deformation methods to compensate for the brain shift. A pipeline for three-dimensional (3-D) vessel reconstruction using three mono-complementary metal-oxide semiconductor cameras has been developed. Vessel centerlines are manually selected in the images. Using the properties of the Hessian matrix, the centerline points are assigned direction information. For correspondence matching, a combination of methods was used. The process starts with epipolar and spatial coherence constraints (geometrical constraints), followed by relaxation labeling and an iterative filtering where the 3-D points are compared to surfaces obtained using the thin-plate spline with decreasing relaxation parameter. Finally, the points are shifted to their local centroid position. Evaluation in virtual, phantom, and experimental images, including intraoperative data from patient experiments, shows that, with appropriate camera positions, the error estimates (root-mean square error and mean error) are similar to 1 mm.

49.	Neuman, Åsa, et al. (författare) Infant wheeze, comorbidities and school age asthma 2014 Ingår i: Pediatric Allergy and Immunology. - : Wiley. - 0905-6157 .- 1399-3038. ; 25:4, s. 380-386 Tidskriftsartikel (refereegranskat)abstract Background: Factors associated with early onset of wheeze have been described, but there is limited knowledge on which of these infant wheezers who will have developed asthma in school age. The aim was to identify clinical risk factors for asthma in the 8-yr-old children that wheezed during infancy in a population-based setting. Methods: Three thousand two hundred and fifty-one children from a population-based birth cohort followed prospectively from infancy until age 8 yr were included in the study. Data were analyzed using multivariate logistic regression analysis. Results: Parents reported any wheeze episode before age 2 yr in 823 subjects (25%). Infant wheezers had an almost fourfold risk of asthma at age 8 [adjusted odds ratio (aOR) 3.68, 95% CI 2.74-4.96], equivalent to an asthma prevalence of 14% compared with 4% among non-wheezers (p < 0.001). After adjustments for sex, exposure to tobacco smoke and indoor dampness/mould, allergic heredity (aOR 1.53, 95% CI 1.02-2.30), increased frequency of wheeze (aOR 3.41, 95% CI 2.09-5.56 for children with >= 3 episodes compared with <= 2 episodes during the first 2 yr of life), infant eczema (aOR 2.31, 95% CI 1.52-3.49), and recurrent abdominal pain (aOR 2.33, 95% CI 1.30-4.16) remained risk factors for school age asthma in the infant wheezing group. Conclusions: Among infant wheezers, allergic heredity, increased severity of wheeze, infant eczema, and recurrent abdominal pain were independent risk factors for asthma at age 8 yr. Among children with three or four of these risk factors, 38% had asthma at school age.
50.	Nyholm, Tufve, et al. (författare) A national approach for automated collection of standardized and population-based radiation therapy data in Sweden 2016 Ingår i: Radiotherapy and Oncology. - : Elsevier BV. - 0167-8140 .- 1879-0887. ; 119:2, s. 344-350 Tidskriftsartikel (refereegranskat)abstract Purpose: To develop an infrastructure for structured and automated collection of interoperable radiation therapy (RT) data into a national clinical quality registry. Materials and methods: The present study was initiated in 2012 with the participation of seven of the 15 hospital departments delivering RT in Sweden. A national RT nomenclature and a database for structured unified storage of RT data at each site (Medical Information Quality Archive, MIQA) have been developed. Aggregated data from the MIQA databases are sent to a national RT registry located on the same IT platform (INCA) as the national clinical cancer registries. Results: The suggested naming convention has to date been integrated into the clinical workflow at 12 of 15 sites, and MIQA is installed at six of these. Involvement of the remaining 3/15 RT departments is ongoing, and they are expected to be part of the infrastructure by 2016. RT data collection from ARIA (R), Mosaiq (R), Eclipse (TM), and Oncentra (R) is supported. Manual curation of RT-structure information is needed for approximately 10% of target volumes, but rarely for normal tissue structures, demonstrating a good compliance to the RT nomenclature. Aggregated dose/volume descriptors are calculated based on the information in MIQA and sent to INCA using a dedicated service (MIQA2INCA). Correct linkage of data for each patient to the clinical cancer registries on the INCA platform is assured by the unique Swedish personal identity number. Conclusions: An infrastructure for structured and automated prospective collection of syntactically inter operable RT data into a national clinical quality registry for RT data is under implementation. Future developments include adapting MIQA to other treatment modalities (e.g. proton therapy and brachytherapy) and finding strategies to harmonize structure delineations. How the RT registry should comply with domain-specific ontologies such as the Radiation Oncology Ontology (ROO) is under discussion.
