  • Apomorphine formulation may influence subcutaneous complications from continuous subcutaneous apomorphine infusion in Parkinson's disease
  • 2020
  • Ingår i: Journal of Neurology. - 0340-5354 .- 1432-1459. ; 267:11, s. 3411-3417
  • Tidskriftsartikel (refereegranskat)abstract
    • Continuous subcutaneous (s.c.) apomorphine infusion is an effective therapy for Parkinson's disease (PD), but a limitation is the formation of troublesome s.c. nodules. Various chemically non-identical apomorphine formulations are available. Anecdotal experiences have suggested that shifting from one of these (Apo-Go PumpFill®; apoGPF) to another (Apomorphine PharmSwed®; apoPS) may influence the occurrence and severity of s.c. nodules. We, therefore, followed 15 people with advanced PD (median PD-duration, 15 years; median "off"-phase Hoehn and Yahr, IV) on apoGPF and with troublesome s.c. nodules who were switched to apoPS. Data were collected at baseline, at the time of switching, and at a median of 1, 2.5, and 7.3 months post-switch. Total nodule numbers (P < 0.001), size (P < 0.001), consistency (P < 0.001), skin changes (P = 0.058), and pain (P ≤ 0.032) improved over the observation period. PD severity and dyskinesias tended to improve and increase, respectively. Apomorphine doses were stable, but levodopa doses increased by 100 mg/day. Patient-reported apomorphine efficacy tended to increase and all participants remained on apoPS throughout the observation period; with the main patient-reported reason being improved nodules. These observations suggest that patients with s.c. nodules caused by apoGPF may benefit from switching to apoPS in terms of s.c. nodule occurrence and severity. Alternatively, observed benefits may have been due to the switch itself. As nodule formation is a limiting factor in apomorphine treatment, a controlled prospective study comparing local tolerance with different formulations is warranted.

  • Omsorgsbegreppet i förskolan : Olika infallsvinklar på ett begrepp och dess relation till en verksamhet. Rapport från nätverk för barnomsorgsforskning, Göteborg 20-21 novemberg 2000
  • 2001
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Denna rapport innehåller texter som presenterats vid en konferens arrangerad inom ramen för Nätverk för barnomsorgsforskningi . Syftet med konferensen var att lyfta upp begreppet omsorg, diskutera dess innebörd, rädda det från retorisk förflackning och samtidigt via dess koppling till verksamheter belysa ett vidare sammanhang. När bamforskning diskuteras har jag på senare tid funnit det väsentligt att peka på att den har en kapacitet att kasta ljus över centrala samhällsfrågor. Forskning om barn bör inte bara vara en forskning om en viss grupp i samhället. Den nyare bamdomsforskningen söker tillämpa ett bamperspektiv. Detta innebär att fenomen studeras såsom de framstår från barnens perspektiv och att inverkan av olika sociala reformer, politiska förändringar och produktion av varor på barns liv belyses. Det handlar alltså både om att söka efter barnens perspektiv och att söka efter konsekvenserna för barnen av olika samhälleliga förändringar. Nya fålt som t.ex. barndomshistoria, barndomssociologi och barndomsantropologi har uppstått och begreppet generation har införts för att markera vikten av att anlägga ett generationsperspektiv på frågor som vanligtvis grupperats på annat sätt.

  • Rasbiologiskt språkbruk i statens rättsprocess mot sameby
  • 2015
  • Ingår i: Dagens Nyheter. - 1101-2447.
  • Tidskriftsartikel (populärvet., debatt m.m.)abstract
    • Statens hantering av forskningsresultat i rättsprocessen med Girjas sameby utgör ett hot mot Sverige som rättsstat och kunskapsnation. Åratal av svensk och internationell forskning underkänns och man använder ett språkbruk som skulle kunna vara hämtat från rasbiologins tid. Nu måste staten ta sitt ansvar och börja agera som en demokratisk rättsstat, skriver 59 forskare.

  • Apomorphine formulation influences subcutaneous complications in continuous apomorphine pump therapy for Parkinson’s disease
  • 2017
  • Ingår i: Movement Disorders.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Objective: To explore if the occurrence and severity of subcutaneous (sc) nodules is influenced by the pharmaceutical formulation of apomorphine used for sc infusion in advanced Parkinson’s disease (PD).Background: Apomorphine infusion is an effective therapy in advanced PD, but a limitation is troublesome sc nodules. Various chemically non-identical apomorphine formulations are available. Anecdotal clinical experience has suggested that shifting from one of these (Apo-Go PumpFill; apoGPF) to another (Apomorphine PharmSwed; apoPS, developed in Sweden) may influence the occurrence and severity of sc nodules.Methods: In this multicenter open-label prospective observational study, 15 people with advanced PD (mean PD- duration, 13.4 years; median Hoehn & Yahr, IV) on apoGPF since a mean of 2.1 years and with troublesome sc nodules were switched to apoPS. Ongoing interventions to treat existing nodules (ultrasound, massage, Hirudoid cream) continued, and apomorphine as well as other drugs was managed according to clinical routines. Data were collected between May 2015 and March 2017; at baseline, at the time of switching (about 2 weeks later), and up to 1.7-4.2 (mean, 2.5) months post-switch follow-up. Primary outcomes were total nodule numbers, size (mm diameter for the 5 worst nodules), consistency (scored 0-3 for the 5 worst nodules), and associated skin changes (scored 0-4 for the 5 worst nodules) and pain (scored 0-5). Patients also rated their perceived PD severity and motor complications (UPDRS IV). Patient preferences 5-12 months post-switch (2-9 months after follow-up) were also recorded.Results: Apomorphine and L-dopa doses did not change over the observation period (P≥0.400). Baseline nodule numbers (7.4 vs. 4.6; P<0.003), size (92.9 vs. 54.1 mm; P=0.016), consistency (11 vs. 5; P=0.003), skin changes (3 vs. 1.5; P=0.205), and average pain (1 vs. 0; P=0.020) improved 11 weeks post-switch. Patient-reported PD severity (P=0.020) and motor fluctuations improved (P=0.051), whereas dyskinesias tended to increase (P=0.205). At 5-12 months post-switch, 13 patients had decided to remain on apoPS; mainly due to improved nodules.Conclusions: These observations suggest that apoPS may have a better safety profile compared to apoGPF in terms of sc nodule occurrence and severity. There is a need for larger, randomized controlled studies for firmer conclusions.

  • Outpatient volumes and medical staffing resources as predictors for continuity of follow-up care during transfer of adolescents with congenital heart disease
  • 2020
  • Ingår i: International Journal of Cardiology. - : Elsevier. - 0167-5273 .- 1874-1754. ; 310, s. 51-57
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Providing continuous follow-up care to patients with congenital heart disease (CHD) remains a challenge in many settings. Previous studies highlight that patients with CHD experience discontinuation of follow-up care, but mainly describe a single-centre perspective, neglecting inter-institutional variations. Hospital-related factors above and beyond patient-related factors are believed to affect continuity of care. The present multicentre study therefore investigated (i) proportion of "no follow-up care"; (ii) transfer destinations after leaving paediatric cardiology; (iii) variation in proportions of no follow-up between centres; (iv) the association between no follow-up and outpatient volumes, and (v) its relationship with staffing resources at outpatient clinics.METHODS: An observational, multicentre study was conducted in seven university hospitals. In total, 654 adolescents with CHD, born between 1991 and 1993, with paediatric outpatient visit at age 14-18 years were included. Transfer status was determined 5 years after the intended transfer to adult care (23y), based on medical files, self-reports and registries.RESULTS: Overall, 89.7% of patients were receiving adult follow-up care after transfer; 6.6% had no follow-up; and 3.7% were untraceable. Among patients in follow-up care, only one remained in paediatric care and the majority received specialist adult CHD care. Significant variability in proportions of no follow-up were identified across centres. Higher outpatient volumes at paediatric outpatient clinics were associated with better continued follow-up care after transfer (OR = 1.061; 95% CI = 1.001 - 1.124). Medical staffing resources were not found predictive.CONCLUSION: Our findings support the theory of hospital-related factors influencing continuity of care, above and beyond patient-related characteristics.

  • Digitala textkompetenser och undervisning. En metatolkande syntes av forskningsstudier om texter, information och multimodalitet i skolan
  • 2020
  • Ingår i: Trettonde nationella konferensen i svenska med didaktisk inriktning: Bildning, utbildning, fortbildning, Linköping, 22-23 november 2018, s. 270-286. - Linköping : Linköpings universitet. - 1651-9132. - 9789179298449
  • Konferensbidrag (refereegranskat)abstract
    • Digital teknik för in nya möjligheter i svenskämnet, som exempelvis multimodala inslag och hypertexter, men ställer också förändrade krav både på elevers läsning, design och utvärdering av texter och lärares undervisning. Förändringar i läroplan och styrdokument tyder på en önskan om att elever ska vara digitalt textkompetenta. Genom en metatol- kande ansats har ett urval av aktuell svensk forskning på området reanalyserats. Syftet är att problematisera och synliggöra de möjligheter och utmaningar den digitala tidsåldern ställer på elever och lärare när det gäller att utveckla digitala textkompetenser. Analysen bygger på studier som spänner över grund- och gymnasieskola och behandlar frågor som rör elevers lärprocesser och lärares beredskap till handledning, stöttning och bedömning när elever söker, tolkar, läser, skapar och hanterar digitala, multimodala texter. Analysen indikerar att elever behöver stöd i att värdera och tolka information samt att designa texter multimodalt. Den visar dessutom att lärare är i behov av redskap för att uppfatta och värdera digitala, multimodala textkompetenser. Kursplanerevideringarna avseende digitalisering uppvisar ett tekniskt perspektiv på användning av digitala verktyg snarare än kvalitativa aspekter av elevernas multimodala textarbete. Konsekvensen blir att lärare, oavsett årskurs eller ämne, har svårt att relatera elevers kunskapsproduktioner till kunskapsmålen i kursplanerna. Det pekar i sin tur på ett behov av att utveckla nya sorters kvalitetsindikatorer för bedömning och betygssättning gällande digital multimodal textanvändning. Om lärare och elever har en gemensam förståelse för digitala, multi- modala texter, kan det utgöra en grund för att forma mer fokuserade och medvetna samtal om kvalitet i digitalt utformat innehåll.

  • Two-year results from a Swedish study on conventional versus accelerated radiotherapy in head and neck squamous cell carcinoma - The ARTSCAN study
  • 2011
  • Ingår i: Radiotherapy and Oncology. - : Elsevier. - 0167-8140 .- 1879-0887. ; 100:1, s. 41-48
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and purpose: Studies on accelerated fractionation (AF) in head and neck cancer have shown increased local control and survival compared with conventional fractionation (CF), while others have been non-conclusive. In 1998 a national Swedish group decided to perform a randomised controlled clinical study of AF. Materials and methods: Patients with verified squamous cell carcinoma of the oral cavity, oropharynx, larynx (except glottic T1-T2, N0) and hypopharynx were included. Patients with prior chemotherapy or surgery were excluded. Patients were randomised to either CF (2Gy/day, 5days/week for 7 weeks, total dose 68Gy) or to AF (1.1Gy+2.0Gy/day, 5days/week for 4.5weeks, total dose 68Gy). An extensive quality assurance protocol was followed throughout the study. The primary end point was loco-regional tumour control (LRC) at two years after treatment. RESULTS: The study was closed in 2006 when 750 patients had been randomised. Eighty-three percent of the patients had stages III-IV disease. Forty eight percent had oropharyngeal, 21% laryngeal, 17% hypopharyngeal and 14% oral cancers. There were no significant differences regarding overall survival (OS) or LRC between the two regimens. The OS at two years was 68% for AF and 67% for CF. The corresponding figures for LRC were 71% and 67%, respectively. There was a trend towards improved LRC for oral cancers treated (p=0.07) and for large tumours (T3-T4) (p=0.07) treated with AF. The AF group had significantly worse acute reactions, while there was no significant increase in late effects. Conclusion: Overall the AF regimen did not prove to be more efficacious than CF. However, the trend towards improved results in AF for oral cancers needs to be further investigated.

  • Does school attendance during initial cancer treatment in childhood increase the risk of infection?
  • 2013
  • Ingår i: Pediatric Blood & Cancer. - : Wiley. - 1545-5009 .- 1545-5017. ; 60:8, s. 1307-1312
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The present study aimed to investigate the relationship between school attendance and infection requiring antimicrobial treatment in children undergoing treatment for cancer. Procedure A national cohort of children aged 7-16 years undergoing cancer treatment was assessed during two observation periods of 19 days each, 1 month (n=89) and 2.5 months (n=89) poststart of treatment. Children free from infection at start of each observation period were included. Multivariable logistic regression analyses were performed including factors potentially associated with start of antimicrobial treatment. Results Twenty-seven (30%) children started antimicrobial treatment during the first observation period. Factors associated with an increased risk of starting antimicrobial treatment were diagnosed with sarcoma (OR=24.37, P=0.002) or non-Hodgkin lymphoma (OR=17.57, P=0.025), having neutropenia (OR=5.92, P=0.020) and age less than 13 years (OR=8.54, P=0.014). During the second observation period, when 20 (22%) children started antimicrobial treatment, the probability of starting treatment was increased in children with neutropenia (OR=4.25, P=0.007). There was no statistically significant association between starting treatment for infection and school attendance. Conclusions In this study, children attending school while undergoing cancer treatment did not run a higher risk of starting antimicrobial treatment than children absent from school. However, there is a need for further studies evaluating risk of infections in children with ongoing cancer treatment.

  • Psychometric properties of the DISABKIDS Chronic Generic Module (DCGM-37) when used in children undergoing treatment for cancer
  • 2010
  • Ingår i: Health and Quality of Life Outcomes. - : Springer Science and Business Media LLC. - 1477-7525. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The aim was to evaluate data quality and psychometric properties of an instrument for measurement of health-related quality of life: DISABKIDS Chronic Generic Module (DCGM-37) used in school-aged children with cancer. Methods: All school-children diagnosed with cancer in Sweden during a two-and-a-half year period were invited to participate in the study. Analysis was performed on combined data from two assessments, two and-a-half and five months after start of cancer treatment (n = 170). The instrument was examined with respect to feasibility, data quality, reliability and construct and criterion-based validity. Results: Missing items per dimension ranged from 0 to 5.3 percent, with a majority below three percent. Cronbach's alpha values exceeded 0.70 for all dimensions. There was support for the suggested groupings of items into dimensions for all but six of the 36 items of the DCGM-37 included in this study. The instrument discriminated satisfactorily between diagnoses reflecting treatment burden. Conclusions: The results indicate satisfactory data quality and reliability of the DCGM-37 when used in children undergoing treatment for cancer. Evaluation of construct validity showed generally acceptable results, although not entirely supporting the suggested dimensionality. Continued psychometric evaluation in a larger sample of children during and after treatment for cancer is recommended.

  • Respiratory health and inflammatory markers : Exposure to respirable dust and quartz and chemical binders in Swedish iron foundries
  • 2019
  • Ingår i: PLOS ONE. - : PLOS. - 1932-6203. ; 14:11
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: To study the relationship between respirable dust, quartz and chemical binders in Swedish iron foundries and respiratory symptoms, lung function (as forced expiratory volume FEV1 and vital capacity FVC), fraction of exhaled nitric oxide (FENO) and levels of club cell secretory protein 16 (CC16) and CRP.METHODS: Personal sampling of respirable dust and quartz was performed for 85 subjects in three Swedish iron foundries. Full shift sampling and examination were performed on the second or third day of a working week after a work free weekend, with additional sampling on the fourth or fifth day. Logistic, linear and mixed model analyses were performed including, gender, age, smoking, infections, sampling day, body mass index (BMI) and chemical binders as covariates.RESULTS: The adjusted average respirable quartz and dust concentrations were 0.038 and 0.66 mg/m3, respectively. Statistically significant increases in levels of CC16 were associated with exposure to chemical binders (p = 0.05; p = 0.01) in the regression analysis of quartz and respirable dust, respectively. Non-significant exposure-responses were identified for cumulative quartz and the symptoms asthma and breathlessness. For cumulative chemical years, non-significant exposure-response were observed for all but two symptoms. FENO also exhibited a non significant exposure-response for both quartz and respirable dust. No exposure-response was determined for FEV1 or FVC, CRP and respirable dust and quartz.CONCLUSIONS: Our findings suggest that early markers of pulmonary effect, such as increased levels of CC16 and FENO, are more strongly associated with chemical binder exposure than respirable quartz and dust in foundry environments.

  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To study the relationship between inhalable dust and cobalt and respiratory symptoms, lung function, exhaled nitric oxide in expired air and CC16 in the Swedish hard metal industry.METHODS: Personal sampling of inhalable dust and cobalt, medical examination including blood sampling was performed for 72 workers. Exposure-response relationships was determined using logistic, linear and mixed model analysis.RESULTS: The average inhalable dust and cobalt concentrations were 0.079 and 0.0017 mg/m, respectively. Statistically significant increased serum levels of CC16 were determined when the high and low cumulative exposures for cobalt were compared. Non-significant exposure-response relationships was observed between cross-shift inhalable dust or cobalt exposures and asthma, nose dripping and bronchitis.CONCLUSIONS: Our findings suggest an exposure-response relationship between inhalable cumulative cobalt exposure and CC16 levels in blood, which may reflect an injury or a reparation process in the lungs.

  • Effect of storage time and temperature on stability of bioactive compounds in aseptically packed beverages prepared from rose hips and sea buckthorn berries
  • 2015
  • Ingår i: Agricultural and Food Science. - 1795-1895 .- 1459-6067. ; 24:4, s. 273-288
  • Tidskriftsartikel (refereegranskat)abstract
    • Rose hips and sea buckthorn berries contain high amounts of beneficial bioactive compounds. In this study the content and stability of natural vitamins and antioxidants were investigated in two fruit beverages made from rose hip powder, sea buckthorn berry puree and white grape juice concentrate, and wheat germ oil in one of the beverages. Beverages were formulated, pasteurised and filled aseptically in Tetra Brik packages and stored up to 35 days at 4 degrees C or 22 degrees C. Samples were analysed for the content of ascorbic acid, carotenoids, major phenolics, tocochromanols, total phenols and total antioxidant capacity as ferric reducing ability. The largest changes occurred during the first 5 days of storage, thereafter mainly ascorbic acid decreased. In the wheat germ oil supplemented beverage, alpha-tocopherol was more rapidly degraded. Negative correlations between the decrease of some carotenoids and tocochromanols, and the increase of some phenolics, suggest relationships of redox reactions specific to the amount of oil supplemented. From the present study we can conclude that additions of oil to beverages should be carefully selected to avoid oxidations of bioactive compounds. Furthermore, packaging of the beverages should be carried out at higher temperatures and thereafter it should be stored at low temperatures (4 degrees C), which decreased oxidation of all bioactive compounds except ascorbic acid.

    • OBJECTIVE: To assess the evidence for risk factors and prevention measures for shoulder injuries in overhead sports.DESIGN: Systematic review with best-evidence synthesis.DATA SOURCES: Medline (Ovid), PubMed (complementary search), Embase (Elsevier), Cochrane (Wiley), SPORTDiscus (Ebsco) and Web of Science Core Collection (Thomson Reuters), from 1 January 1990 to 15 May 2017.ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled trials, cohort studies and case-control studies on risk factors or prevention measures for shoulder injuries in overhead sports. The eligible studies were quality assessed using the Scottish Intercollegiate Guidelines Network criteria.RESULTS: Of 4778 studies identified, 38 were eligible for quality review and 17 met the quality criteria to be included in the evidence synthesis. One additional quality study presented a shoulder injury prevention programme. Most studies focused on baseball, lacrosse or volleyball (n=13). The risk factors examined included participation level (competition vs training) (n=10), sex (n=4), biomechanics (n=2) and external workload (n=2). The evidence for all risk factors was limited or conflicting. The effect of the prevention programme within the subgroup of uninjured players at baseline was modest and possibly lacked statistical power.CONCLUSIONS: All investigated potential risk factors for shoulder injury in overhead sports had limited evidence, and most were non-modifiable (eg, sex). There is also limited evidence for the effect of shoulder injury prevention measures in overhead sports.PROSPERO TRIAL REGISTRATION NUMBER: CRD42015026850.

  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants because of anticipation of poor long-term outcome. Of 497 surviving infants, 10% developed severe intraventricular haemorrhage (IVH), 5.7% cystic periventricular leucomalacia (cPVL), 41% septicaemia and 5.8% necrotizing enterocolitis (NEC); 61% had patent ductus arteriosus (PDA) and 34% developed retinopathy of prematurity (ROP) stage >= 3. Eighty-five per cent needed mechanical ventilation and 25% developed severe bronchopulmonary dysplasia (BPD). Forty-seven per cent survived to one year of age without any severe IVH, cPVL, severe ROP, severe BPD or NEC. Tocolysis increased and prolonged mechanical ventilation decreased the chances of survival without these morbidities. Maternal smoking and higher gestational duration were associated with lower risk of severe ROP, whereas PDA and poor growth increased this risk. Conclusion: Half of the infants surviving extremely preterm birth suffered from severe neonatal morbidities. Studies on how to reduce these morbidities and on the long-term health of survivors are warranted.

  • Coffee and tea consumption and risk of pre- and postmenopausal breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort study
  • 2015

  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Specific coffee subtypes and tea may impact risk of pre- and post-menopausal breast cancer differently. We investigated the association between coffee (total, caffeinated, decaffeinated) and tea intake and risk of breast cancer. Methods: A total of 335,060 women participating in the European Prospective Investigation into Nutrition and Cancer (EPIC) Study, completed a dietary questionnaire from 1992 to 2000, and were followed-up until 2010 for incidence of breast cancer. Hazard ratios (HR) of breast cancer by country-specific, as well as cohort-wide categories of beverage intake were estimated. Results: During an average follow-up of 11 years, 1064 premenopausal, and 9134 postmenopausal breast cancers were diagnosed. Caffeinated coffee intake was associated with lower risk of postmenopausal breast cancer: adjusted HR = 0.90, 95% confidence interval (CI): 0.82 to 0.98, for high versus low consumption; P-trend = 0.029. While there was no significant effect modification by hormone receptor status (P = 0.711), linear trend for lower risk of breast cancer with increasing caffeinated coffee intake was clearest for estrogen and progesterone receptor negative (ER-PR-), postmenopausal breast cancer (P = 0.008). For every 100 ml increase in caffeinated coffee intake, the risk of ER-PR- breast cancer was lower by 4% (adjusted HR: 0.96, 95% CI: 0.93 to 1.00). Non-consumers of decaffeinated coffee had lower risk of postmenopausal breast cancer (adjusted HR = 0.89; 95% CI: 0.80 to 0.99) compared to low consumers, without evidence of dose-response relationship (P-trend = 0.128). Exclusive decaffeinated coffee consumption was not related to postmenopausal breast cancer risk, compared to any decaffeinated-low caffeinated intake (adjusted HR = 0.97; 95% CI: 0.82 to 1.14), or to no intake of any coffee (HR: 0.96; 95%: 0.82 to 1.14). Caffeinated and decaffeinated coffee were not associated with premenopausal breast cancer. Tea intake was neither associated with pre- nor post-menopausal breast cancer. Conclusions: Higher caffeinated coffee intake may be associated with lower risk of postmenopausal breast cancer. Decaffeinated coffee intake does not seem to be associated with breast cancer.

  • Staphylococcus aureus-derived factors induce IL-10, IFN-gamma and IL-17A-expressing FOXP3(+)CD161(+) T-helper cells in a partly monocyte-dependent manner
  • 2016
  • Ingår i: Scientific Reports. - : Springer Science and Business Media LLC. - 2045-2322. ; 6
  • Tidskriftsartikel (refereegranskat)abstract
    • Staphylococcus aureus (S. aureus) is a human pathogen as well as a frequent colonizer of skin and mucosa. This bacterium potently activates conventional T-cells through superantigens and it is suggested to induce T-cell cytokine-production as well as to promote a regulatory phenotype in T-cells in order to avoid clearance. This study aimed to investigate how S. aureus impacts the production of regulatory and pro-inflammatory cytokines and the expression of CD161 and HELIOS by peripheral CD4(+)FOXP3(+) T-cells. Stimulation of PBMC with S. aureus 161:2-cell free supernatant (CFS) induced expression of IL-10, IFN-gamma and IL-17A in FOXP3(+) cells. Further, CD161 and HELIOS separated the FOXP3(+) cells into four distinct populations regarding cytokine-expression. Monocyte-depletion decreased S. aureus 161:2-induced activation of FOXP3(+) cells while pre-stimulation of purified monocytes with S. aureus 161:2-CFS and subsequent co-culture with autologous monocyte-depleted PBMC was sufficient to mediate activation of FOXP3(+) cells. Together, these data show that S. aureus potently induces FOXP3(+) cells and promotes a diverse phenotype with expression of regulatory and pro-inflammatory cytokines connected to increased CD161-expression. This could indicate potent regulation or a contribution of FOXP3(+) cells to inflammation and repression of immune-suppression upon encounter with S. aureus.

  • Barn som medforskare av matlandskap. Del 1: Medforskning
  • 2010
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Att ta med barn i forskningsprocessen är undantag snarare än regel i barndomsforskning. Det är även mycket ovanligt när det gäller forskning inom fältet mat och hälsa som domineras av kvantitativa studier. De flesta av dessa studier har folkhälsovetenskapliga eller kostvetenskapliga utgångspunkter där man försöker följa, mäta effekterna av och utvärdera olika interventioner riktade mot barn. Forskarna i BAMM ville inte forska om barn utan med dem. Deras utgångspunkt var barnen och deras intressefokus och frågeställningar. Vad är intressant för dem? Vad har de för kunskaper och vad är de nyfikna på att få veta mer om? Hur tar de reda på mer om det de är intresserade av? Hur sammanställer och presenterar de sin forskning? Hur föreslår och visualiserar de förändringar? Kan barns forskning göra skillnad? För dem? För samhället? Detta metodiska angreppssätt innebar också med nödvändighet en kritik av gängse uppifrån-och-ner-modeller för interventioner riktade mot barn. Fältarbetet bedrevs i två fjärdeklasser med totalt 45 barn på en skola i en av Göteborgs kranskommuner. Medforskarna arbetade i grupper på 7-8, med en eller två av forskarna som handledare. Forskarnas ambition som handledare var att uppmärksamma medforskarnas intressen och önskemål och låta dem leda forskarna runt i sina matlandskap. Det var inte bestämt i detalj hur medforskandet skulle gå till utan forskningssamarbetet fick växa fram tillsammans med barnen. Genom BAMM fick forskarna uppslag för hur barns matmiljöer kan bli mer hälsofrämjande. Det behövs insatser på såväl individ, som skol- och kommunnivå. Utgångspunkten är att barn ska bemötas som individer med resurser att tillföra i ett hälsofrämjande arbete. Det innebär att ta vara på barns erfarenheter och kunskaper och att ge dem möjligheter, både i och utanför skolan, att ta reda på mer om det de är intresserade av. Det är också viktigt att ta matglädje och sinnlighet på allvar och inte minst att ge barn reell möjlighet att vara delaktiga i beslut som fattas rörande deras matlandskap.

    • In this article, we discuss children’s becoming as food consumers in the intersection of various foodscapes. We draw from a project, Children as co-researchers of foodscapes, where we have been working with children as co-researchers, using basically ethnographic methods, and as co-designers in a collaborative design effort. This article focuses on the findings from a theoretically inspired perspective, using the concept of foodscapes. These are food-related structures of different kinds, which evolve as the child explores them and where children as food consumers are generated. In this article, we highlight the scapes of taste, routines, people, things, commerce, child (as opposed to adult) and health and give brief accounts of the way the children related to them. Finally, we turn to the benefits of working with foodscapes for a better understanding of children’s becoming as food consumers in the intersection of various foodscapes. This article is based on data gathered by the children, but also on our fieldwork notes and observations following the children in their foodscapes.

    • Forskargruppen KRIHS, Kris och risk i det heterogena samhället, har fått uppdraget att skriva en kunskapsöversikt inom ramen för MSB:s verksamhetsområden skydd mot olyckor, krishantering och civil beredskap. Uppdraget har gjorts i samarbete med Eva-Lena Demarin som stått för stora delar av sammanställningen av tidigare forskning samt delar av övriga avsnitt. Undertecknad ansvarar för översiktens vetenskapliga kvalitet. Kunskapsöversikten är dock ett resultat av forskargruppens gemensamma ansträngningar. Tillsammans med Eva-Lena har gruppen träffats vid fem tillfällen varav vid ett seminarium där texten diskuterats och reviderats. De som varit med och diskuterat, samlat in material och/eller skrivit delar av översikten är förutom ovan nämnda, Erna Danielsson, Sara Ekholm, Linda Eliasson, Roine Johansson, Jörgen Sparf, Erika Wall och Susanna Öhman.Då både tiden och utrymmet har varit begränsat gör vi inga anspråk på att kunskapsöversikten är heltäckande. Den ska snarare ses som en ganska grovkorning bild av de senaste tio årens risk- och krisforskning rörande uppfattningar, kommunikation och organisation. Det huvudsakliga bidraget är att översikten identifierar vissa områden där kunskapsuppbyggnad behövs. På så sätt kan översikten ses som en karta där vissa kompassriktningar markerats utifrån vilka MSB kan välja vilka som passar myndighetens framtida verksamhet.

  • Area of ischemia assessed by physicians and software packages from myocardial perfusion scintigrams
  • 2014
  • Ingår i: BMC Medical Imaging. - : BioMed Central. - 1471-2342. ; 14:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The European Society of Cardiology recommends that patients with greater than 10% area of ischemia should receive revascularization. We investigated inter-observer variability for the extent of ischemic defects reported by different physicians and by different software tools, and if inter-observer variability was reduced when the physicians were provided with a computerized suggestion of the defects. Methods: Twenty-five myocardial perfusion single photon emission computed tomography (SPECT) patients who were regarded as ischemic according to the final report were included. Eleven physicians in nuclear medicine delineated the extent of the ischemic defects. After at least two weeks, they delineated the defects again, and were this time provided a suggestion of the defect delineation by EXINI Heart(TM) (EXINI). Summed difference scores and ischemic extent values were obtained from four software programs. Results: The median extent values obtained from the 11 physicians varied between 8% and 34%, and between 9% and 16% for the software programs. For all 25 patients, mean extent obtained from EXINI was 17.0% (+/- standard deviation (SD) 14.6%). Mean extent for physicians was 22.6% (+/- 15.6%) for the first delineation and 19.1% (+/- 14.9%) for the evaluation where they were provided computerized suggestion. Intra-class correlation (ICC) increased from 0.56 (95% confidence interval (CI) 0.41-0.72) to 0.81 (95% CI 0.71-0.90) between the first and the second delineation, and SD between physicians were 7.8 (first) and 5.9 (second delineation). Conclusions: There was large variability in the estimated ischemic defect size obtained both from different physicians and from different software packages. When the physicians were provided with a suggested delineation, the inter-observer variability decreased significantly.

  • Sustainable UNiversity Life (SUN) study : Protocol for a prospective cohort study of modifiable risk and prognostic factors for mental health problems and musculoskeletal pain among university students
  • 2022
  • Ingår i: BMJ Open. - : BMJ. - 2044-6055. ; 12:4
  • Tidskriftsartikel (refereegranskat)abstract
    • INTRODUCTION: Mental health problems and musculoskeletal pain are common health problems among young adults including students. Little is known about the aetiology and prognosis of these problems in university students. We aim to determine the role of personal, sociodemographic, academic and environmental factors for risk and prognosis of symptoms of depression, anxiety and stress as well as musculoskeletal pain in university students. The constructs that will be studied are based on the biopsychosocial model and psychopathology associated with disabling pain. This model acknowledges illness to consist of interrelated mechanisms categorised into biological, psychological, environmental and social cues.METHODS AND ANALYSIS: This cohort study aims to recruit around 5000 Swedish full-time students. Data will be collected using five online surveys during one academic year. A subgroup (n=1851) of the cohort, recruited before the COVID-19 pandemic, receive weekly text messages with three short questions assessing mood, worry and pain, sent through the web-based platform SMS-track . Statistical analyses will include Kaplan-Meier estimates, Cox regression analyses, multinomial logistic regression analyses and generalised estimating equations. We will assess effect measure modification when relevant and conduct sensitivity analyses to assess the impact of lost to follow-up.PROTOCOL AMENDMENTS: Due to opportunity and timing of the study, with relevance to the outbreak of the COVID-19 pandemic, this study further aims to address mental health problems, musculoskeletal pain and lifestyle in university students before and during the pandemic.ETHICS AND DISSEMINATION: The Sustainable UNiversity Life study was approved by the Swedish ethics authority (2019-03276; 2020-01449). Results will be disseminated through peer-reviewed research papers, reports, research conferences, student theses and stakeholder communications.TRIAL REGISTRATION NUMBER: NCT04465435.

  • A multicentre simulation study of planar whole-body bone scintigraphy in Sweden
  • 2022
  • Ingår i: EJNMMI Physics. - : Springer Science and Business Media LLC. - 2197-7364. ; 9:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Whole-body bone scintigraphy is a clinically useful non-invasive and highly sensitive imaging method enabling detection of metabolic changes at an early stage of disease, often earlier than with conventional radiologic procedures. Bone scintigraphy is one of the most common nuclear medicine methods used worldwide. Therefore, it is important that the examination is implemented and performed in an optimal manner giving the patient added value in the subsequent care process. The aim of this national multicentre survey was to investigate Swedish nuclear medicine departments compliance with European practice guidelines for bone scintigraphy. In addition, the effect of image acquisition parameters on the ability to detect metabolic lesions was investigated. Methods: Twenty-five hospital sites participated in the study. The SIMIND Monte Carlo (MC) simulation and the XCAT phantom were used to simulate ten fictive patient cases with increased metabolic activity distributed at ten different locations in the skeleton. The intensity of the metabolic activity was set into six different levels. Individual simulations were performed for each site, corresponding to their specific camera system and acquisition parameters. Simulated image data sets were then sent to each site and were visually evaluated in terms of if there was one or several locations with increased metabolic activity relative to normal activity. Result: There is a high compliance in Sweden with the EANM guidelines regarding image acquisition parameters for whole-body bone scintigraphy. However, up to 40% of the participating sites acquire lower count density in the images than recommended. Despite this, the image quality was adequate to maintain a stable detection level. None of the hospital sites or individual responders deviated according to the statistical analysis. There is a need for at least 2.5 times metabolic activity compared to normal for a lesion to be detected. Conclusion: The imaging process is well harmonized throughout the country and there is a high compliance with the EANM guidelines. There is a need for at least 2.5 times the normal metabolic activity for a lesion to be detected as abnormal.

  • Optimizing yield and quality in malting barley by the governance of field cultivation conditions
  • 2018
  • Ingår i: Journal of Cereal Science. - : Elsevier BV. - 0733-5210 .- 1095-9963. ; 82, s. 230-242
  • Tidskriftsartikel (refereegranskat)abstract
    • This study evaluates how cultivation location, year, soil conditions and starter fertilizer interact and determine yield and quality of malting barley. Size exclusion high performance liquid chromatography (SE-HPLC) was applied to determine protein composition in mature and malted barley.The effects of starter fertilizer treatments on yield and quality of malting barley was largely hidden by the impact of growing location and cultivation year on these parameters. Here, the highest yield and the lowest grain protein concentration was found in samples cultivated on sandy soil with adequate precipitation and a relatively low soil temperature (below 15-17 degrees C) during grain filling. In malted grains, the general change in protein composition as related to mature grains, was a decrease in the polymerized protein fractions and an increase in the more easily extractable and smaller proteins. However, cultivation conditions impacted the changes of the protein fractions; the highest break-down rates of polymerized proteins was found for samples cultivated on sandy soil with enough precipitation and a relatively low soil temperature (below 15-17 degrees C) during grain filling. Thus, the sandy soil, enough precipitation and relatively low soil temperature were the most beneficial both for grain yield and for protein based quality of the malting barley.

  • Slutrapport för projektet "Optimerad näringssammansättning och gödselplacering för ökad skörd och förbättrad kvalité hos maltkorn – fältförsök"
  • 2012
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • I ett tidigare pilotprojekt i Biotronen, Alnarp, har forskare försökt hitta en optimerad näringssammansättning för maltkorn. Resultaten indikerade att icke optimerade näringslösningar, till skillnad från deras optimerade, fördröjde skottens tillväxtstart något. När grundgödslingen utfördes i form av en bredspridning med myllning samt där tillskott av en optimerad näringslösning tillfördes i såraden (sammyllad startgiva), blev antalet skott 29 % högre och torrsubstansen 24 % högre än för normalledet där grundgödslingen utfördes i form av ”kombisådd” utan extra näringstillskott i såfåran. Hypotesen är att skörden ökar vid användning av en optimerad näringssammansättning samt att en sammyllad startgiva vid sådd, speciellt vid tidig sådd på våren, leder till en snabbare tillväxt hos grödan, en tidigare och större skörd, ett minskat gödslingsbehov genom bättre växtnäringsutnyttjande och minskad utlakningsrisk, vilket resulterar i en förbättrad odlingsekonomi och en minskad miljöbelastning från odlingen. Syftet med projektet är att i fält fastställa om en liten mängd näringstillskott med en optimerad sammansättning i kärnans direkta närhet kan öka avkastningen samt kvaliteten hos maltkorn jämfört med att placera all näring skiljt från kärnan genom kombisådd eller bredspridning av konstgödseln. Även MAP som näringstillskott ingår i några led. Fältförsök utfördes på tre platser i södra Skåne med 6 led och 6 upprepningar under år 1 och på två platser i södra Skåne med 7 led och 6 upprepningar under år 2 och 3. De 7 leden var: 1 Sammyllad NPKmikro-startgiva kombinerat med en radmyllad NPK-huvudgiva 2 Ingen startgiva. Endast en radmyllad NPK-huvudgiva 3 Sammyllad NPKmikro-startgiva kombinerat med en bredspridd myllad NPK-huvudgiva 4 Ingen startgiva. Endast en bredspridd myllad NPK-huvudgiva 5 Sammyllad MAP-startgiva kombinerat med en bredspridd myllad NPK-huvudgiva 6 Sammyllad MAP-startgiva kombinerat med en radmyllad NPK-huvudgiva 7 Kontroll: Ingen startgiva. Endast en bredspridd myllad NS-huvudgiva (ingick inte år 1) Resultaten från projektet visade att såväl odlingsåret som odlingsplatsen spelade stor roll både för uppkomst, tillväxt, avkastning, kvalitet och proteinsammansättning hos maltkorn vid skörd och efter mältning. Behandlingen (i form av näringstillförsel beskriven ovan) påverkade dock samtliga dessa parametrar marginellt i fält när resultaten jämfördes över tre år och 4-7 odlingsplatser (eftersom inte motsvarande gårdar och fält användes under de olika år som försöket pågick behandlades varje odling som en odlingsplats). Mycket få signifikanta skillnader erhölls som kunde förklaras rakt av ifrån behandlingen. Vissa signifikanta skillnader kunde emellertid detekteras under specifika år och på specifika platser vilket indikerar att det finns samverkansfaktorer mellan odlingsår, odlingsplats och behandling. Detta innebär att det skulle kunna löna sig att behandla enligt någon av ovanstående typer av behandling (led) på en specifik plats och under ett specifikt år. Mycket mer kunskap behövs dock gällande interaktioner och när olika behandlingar lönar sig både ekonomiskt och ur miljösynpunkt. Ett försök gjordes inom detta projekt att korrelera jord- och klimatdata med avkastnings- och kvalitetsdata. Inga tydliga korrelationer erhölls dock vilket kan förklaras av det låga antalet av försöksplatser (totalt 7 st). Slutsatserna från detta projekt blir således att inga generella rekommendationer kan göras rakt av gällande förändrad näringstillförsel vid odling av maltkorn. Betydligt mer undersökningar måste göras om inverkan och interaktion av olika faktorer vid odling av maltkorn innan mer specifika rekommendationer kommer att kunna göras. Mer specifikt behövs mer kunskap om hur olika mark-, jord- och klimatfaktorer samverkar med näringstillförsel för att generera avkastning och kvalitet hos maltkorn

  • A novel variant in MYLK causes thoracic aortic dissections : genotypic and phenotypic description
  • 2016
  • Ingår i: BMC Medical Genetics. - : Springer Science and Business Media LLC. - 1471-2350. ; 17
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Mutations in MYLK cause non- syndromic familial thoracic aortic aneurysms and dissections (FTAAD). Very little is known about the phenotype of affected families. We sought to characterize the aortic disease and the presence of other vascular abnormalities in FTAAD caused by a deletion in MYLK and to compare thoracic aortic diameter and stiffness in mutation carriers and non-carriers.Methods: We studied FTAAD in a 5-generation family that included 19 living members. Exome sequencing was performed to identify the underlying gene defect. Aortic elastic properties measured by TTE, MRI and pulse wave velocity were then compared between mutation carriers and non-carriers.Results: Exome sequencing led to the identification of a 2-bp deletion in MYLK (c3272_ 3273del, p. Ser1091*) that led to a premature stop codon and nonsense-mediated decay. Eleven people were mutation carriers and eight people were non-carriers. Five aortic ruptures or dissections occurred in this family, with two survivors. There were no differences in aortic diameter or stiffness between carriers and non-carriers of the mutation.Conclusions: Individuals carrying this deletion in MYLK have a high risk of presenting with an acute aortic dissection or rupture. Aortic events occur over a wide range of ages and are not always preceded by obvious aortic dilatation. Aortic elastic properties do not differ between carriers and non-carriers of this mutation, rendering it uncertain whether and when carriers should undergo elective prophylactic surgery.

  • Familial thoracic aortic aneurysms and dissections : studies on genotype and phenotype
  • 2017
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Background: Thoracic aortic aneurysms and dissections (TAAD) have a genetic component with an estimated 20-25% of the patients having a positive family history. An aneurysm often precedes a dissection. Acute aortic dissections are associated with high mortality and morbidity, even when operated on. Complications due to prophylactic surgery are considerably fewer. Therefore, patients at risk for dissection should be identified, followed-up and evaluated for prophylactic intervention.Aims: 1. To establish reference values for ascending (AoA) and descending aortic (AoD) diameters measured by computed tomography. 2. To study the effectiveness of phenotypic cascade screening in families with an inherited form of thoracic aortic aneurysms and dissections (FTAAD) and to address questions that arise when screening for a genetic disorder is applied. 3. To study the agreement of aortic diameters obtained by TTE and MRI and to study aortic stiffness in individuals from families with FTAAD. 4. To perform exome sequencing in order to identify pathogenic sequence variants causing FTAAD, to characterize the phenotype, and to compare thoracic aortic diameter and stiffness in mutation carriers and non-carriers.Results: Paper I: The diameter of the thoracic aorta increased by 0.17 mm (0.12 – 0.20 mm) per year. The mean sex-related difference in diameter was 1.99 mm (1.28 – 2.60 mm) with men having larger aortas than women. The mean difference in aortic diameter per unit BMI was 0.27 mm (0.14 – 0.44 mm). Upper normal limits for the AoA can be calculated by the formula D (mm)=31+0.16*age and for the AoD by D (mm)=21+0.16*age.Paper II: Of 106 individuals from families with FTAAD but without known thoracic aortic disease, 19 individuals (18%) were identified to have a dilated AoA. The expected number of individuals in this group with an autosomal dominant disease would have been 40 (p<0.0001). In first-degree relatives younger than 40, we found only one individual with a dilated aorta although the expected number of individuals with disease causing mutation would have been 10.Paper III: Of 116 individuals investigated, 21 were identified with thoracic aortic dilatation and 95 individuals with normal thoracic aortic diameter. Aortic stiffness increased with age and diameter. The individuals with aortic dilatation were older than those without (49 vs. 37 years, p=0.001) and showed lower aortic elastic properties. The diameters measured by TTE and MRI correlated strongly (r2=0.93). The mean difference in diameters between the two methods was 0.72 mm (95% CI 0.41-1.02) with TTE giving larger diameters than MRI.Paper IV: From exome sequencing and segregation analysis, a 2-bp deletion in the MYLK gene (c.3272_3273del) was identified to cause FTAAD. The age and the aortic diameter at dissection or rupture varied in the family members. We did not find any differences in aortic diameter, aortic stiffness, or pulse wave velocity between carriers and non-carriers.Conclusions: Thoracic aortic diameter increases with age, and sex and body size are also associated with the diameter. In FTAAD, screening identifies family members with a previously unknown aortic dilatation. However, a normal aortic diameter does not exclude an individual from being a carrier of FTAAD. TTE can be used in follow-up for the ascending aorta. Individuals identified to have a dilated thoracic aorta have increased aortic stiffness compared to individuals with normal thoracic aortic diameter. The MYLK mutation (c.3272_3273del) causes thoracic aortic dissections with variable clinical expression. No differences in aortic stiffness were identified between MYLK mutation carriers and non-carriers.

  • Screening for familial thoracic aortic aneurysms with aortic imaging does not detect all potential aarriers of the disease
  • 2015
  • Ingår i: Aorta. - : Georg Thieme Verlag KG. - 2325-4637. ; 3:1, s. 1-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: About 20% of patients with thoracic aortic aneurysm or dissection (TAAD) have a first-degree relative with a similar disease. The familial form (FTAAD) of the disease is inherited in an autosomal-dominant pattern. Current guidelines for thoracic aortic disease recommend screening of first-degree relatives of TAAD patients. In known familial disease, screening of both first- and second-degree relatives is recommended. However, the outcomes of such a screening program are unknown.Methods: We screened all first- and second-degree relatives in seven families with known FTAAD with echo- cardiography. No underlying gene defect had been detected in these families.Results: Of 119 persons investigated, 13 had known thoracic aortic disease. In the remaining 106 cases, we diagnosed 19 additional individuals with a dilated ascending thoracic aorta; for an autosomal-dominant disease, the expected number of individuals in this group would have been 40 (p<0.0001). Further, only one of the 20 first-degree relatives younger than 40 years had a dilated aorta, although the expected number of individuals with a disease-causing mutation would have been 10.Conclusions: In most families with TAAD, a diagnosis still relies on measuring the diameter of the thoracic aorta. We show that a substantial number of previously unknown cases of aortic dilatation can be identified by screening family members. It is, however, not possible to consider anyone free of the condition, even if the aortic diameter is normal, especially at a younger age.

  • Ökad skörd och bättre kvalitet hos maltkorn genom optimerad näringssammansättning och gödselplacering?
  • 2009
  • Ingår i: LTJ-fakultetens faktablad.
  • Annan publikation (populärvet., debatt m.m.)abstract
    • Enbart sammyllad startgiva, även om denna är av en optimerad näringssammansättning, påverkar varken antalet uppkomna plantor, avkastning eller kvalitet hos maltkorn signifikant. Andra parametrar, t.ex. jord och eventuellt väderförhållanden är av större betydelse för både avkastningen och kvaliteten. Våra försök i Biotronen i Alnarp påvisade framför allt betydelsen av jorden och dess ursprung, trots att syftet var att utveckla möjligheterna till otimal näringssammansättning och gödselplacering. Den stora skillnaden i avkastning och kvalitet hos maltkornet som jordens ursprung gav upphov till genererades trots att skillnaden mellan jordarna troligen är mindre än i fält när odlingen sker i Biotronen och dessutom är väderförhållandena identiska i Biotronen, vilket inte är fallet i fält.

  • Genome-wide sequencing for the identification of rearrangements associated with Tourette syndrome and obsessive-compulsive disorder
  • 2012
  • Ingår i: BMC Medical Genetics. - : Springer Science and Business Media LLC. - 1471-2350. ; 13, s. 123-
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Tourette Syndrome (TS) is a neuropsychiatric disorder in children characterized by motor and verbal tics. Although several genes have been suggested in the etiology of TS, the genetic mechanisms remain poorly understood. Methods: Using cytogenetics and FISH analysis, we identified an apparently balanced t(6,22)(q16.2;p13) in a male patient with TS and obsessive-compulsive disorder (OCD). In order to map the breakpoints and to identify additional submicroscopic rearrangements, we performed whole genome mate-pair sequencing and CGH-array analysis on DNA from the proband. Results: Sequence and CGH array analysis revealed a 400 kb deletion located 1.3 Mb telomeric of the chromosome 6q breakpoint, which has not been reported in controls. The deletion affects three genes (GPR63, NDUFA4 and KLHL32) and overlaps a region previously found deleted in a girl with autistic features and speech delay. The proband's mother, also a carrier of the translocation, was diagnosed with OCD and shares the deletion. We also describe a further potentially related rearrangement which, while unmapped in Homo sapiens, was consistent with the chimpanzee genome. Conclusions: We conclude that genome-wide sequencing at relatively low resolution can be used for the identification of submicroscopic rearrangements. We also show that large rearrangements may escape detection using standard analysis of whole genome sequencing data. Our findings further provide a candidate region for TS and OCD on chromosome 6q16.

  • Experiences of Stress : A Focus Group Interview Study Among Swedish Adolescents During the COVID-19 Pandemic
  • 2021
  • Ingår i: Journal of School Nursing. - : SAGE Publications Inc.. - 1059-8405 .- 1546-8364. ; , s. 1-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Adolescence can be a stressful period in life. The period contains challenges associated with the transition from childhood to adulthood (body changes, changes in interpersonal relationships, and identity changes). The aim was to investigate experiences of stress among adolescents in addition to stress related to the COVID-19 pandemic. Focus group interviews (n = 8) were conducted with girls (n = 22) and boys (n = 19) aged 13–15 in southern Sweden. The transcribed interviews were analyzed with qualitative content analysis. Analysis of the collected material resulted in two categories with four sub-categories each of which highlights adolescents’ experiences of stress. The results show that adolescents’ have a variety of experiences of stress, i.e., what they mean are the sources of stress and how stress is manifested. The adolescents experienced how stress was manifested both physically and emotionally. This affected both their sleep and performance. The adolescents reflected on both positive and negative manifestations of stress.

  • Clinical significance in self-rated HRQoL among survivors after childhood cancer - demonstrated by anchor-based thresholds
  • 2014
  • Ingår i: Acta Oncologica. - : Taylor & Francis. - 0284-186X .- 1651-226X. ; 53:4, s. 486-492
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There is a need to establish clinically relevant thresholds (anchors) for identification of differences in health-related quality of life (HRQoL) and thereby provide stronger evidence regarding the HRQoL of childhood cancer survivors.AIM: To investigate HRQoL in childhood cancer survivors with a standardised instrument and to establish thresholds for clinically significant differences by using qualitative interviews as anchors. An additional aim was to investigate survivors' HRQoL in relation to an age-matched comparison group without cancer experience.MATERIAL AND METHODS: Self-rated HRQoL (KIDSCREEN-27) was assessed in a national cohort of survivors (n = 63, aged 12-22) and a comparison group (n = 257, aged 11-23). Findings from qualitative interview data were also used (n = 61); three subgroups ("Feeling like anyone else"; "Feeling almost like others"; "Feeling different") were identified based on survivors own perception of influence on daily life. Effect size calculations based on means from the KIDSCREEN-27 dimensions were performed using the subgroups as anchors to indicate clinical importance. Furthermore, standard multiple regression analyses were performed. Results. Effect sizes between the subgroups "Feeling like anyone else" and "Feeling almost like others" and the group "Feeling different" were large for all dimensions (1.04-2.07). The multiple regression models showed that being a survivor was significantly associated with one of the dimensions, School Environment, where survivors scored higher HRQoL. Furthermore, female sex and older age (17-23 years) significantly contributed to lower self-rated HRQoL. Conclusion. In clinical practice the KIDSCREEN-27 could be a useful screening tool to identify survivors of childhood cancer in need of extra support, using KIDSCREEN dimension mean values of 45 or less as thresholds. Larger scale studies are recommended to identify and test thresholds with regard to different age groups and time since diagnosis.
