  • European genome-wide association study identifies SLC14A1 as a new urinary bladder cancer susceptibility gene.
  • 2011
  • Ingår i: Human molecular genetics. - 1460-2083. ; 20:21, s. 4268-81
  • Tidskriftsartikel (refereegranskat)abstract
    • Three genome-wide association studies in Europe and the USA have reported eight urinary bladder cancer (UBC) susceptibility loci. Using extended case and control series and 1000 Genomes imputations of 5 340 737 single-nucleotide polymorphisms (SNPs), we searched for additional loci in the European GWAS. The discovery sample set consisted of 1631 cases and 3822 controls from the Netherlands and 603 cases and 37 781 controls from Iceland. For follow-up, we used 3790 cases and 7507 controls from 13 sample sets of European and Iranian ancestry. Based on the discovery analysis, we followed up signals in the urea transporter (UT) gene SLC14A. The strongest signal at this locus was represented by a SNP in intron 3, rs17674580, that reached genome-wide significance in the overall analysis of the discovery and follow-up groups: odds ratio = 1.17, P = 7.6 × 10(-11). SLC14A1 codes for UTs that define the Kidd blood group and are crucial for the maintenance of a constant urea concentration gradient in the renal medulla and, through this, the kidney's ability to concentrate urine. It is speculated that rs17674580, or other sequence variants in LD with it, indirectly modifies UBC risk by affecting urine production. If confirmed, this would support the 'urogenous contact hypothesis' that urine production and voiding frequency modify the risk of UBC.

  • Psychological, pharmacological, and combined treatments for binge eating disorder: a systematic review and meta-analysis
  • 2018
  • Ingår i: Peerj. - : PeerJ. - 2167-8359. ; 6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To systematically review the efficacy of psychological, pharmacological, and combined treatments for binge eating disorder (BED). Results: We found 45 unique studies with low/medium risk of bias, and moderate support for the efficacy of cognitive behavior therapy (CBT) and CBT guided self-help (with moderate quality of evidence), and modest support for interpersonal psychotherapy (IPT), selective serotonin reuptake inhibitors (SSRI), and lisdexamfetamine (with low quality of evidence) in the treatment of adults with BED in terms of cessation of or reduction in the frequency of binge eating. The results on weight loss were disappointing. Only lisdexamfetamine showed a very modest effect on weight loss (low quality of evidence). While there is limited support for the long-term effect of psychological treatments, we have currently no data to ascertain the long-term effect of drug treatments. Some undesired side effects are more common in drug treatment compared to placebo, while the side effects of psychological treatments are unknown. Direct comparisons between pharmaceutical and psychological treatments are lacking as well as data to generalize these results to adolescents. Conclusion: We found moderate support for the efficacy of CBT and guided self-help for the treatment of BED. However, IPT, SSRI, and lisdexamfetamine received only modest support in terms of cessation of or reduction in the frequency of binge eating. The lack of long-term follow-ups is alarming, especially with regard to medication. Long-term follow-ups, standardized assessments including measures of quality of life, and the study of underrepresented populations should be a priority for future research.

  • Integrated Molecular Analysis of Undifferentiated Uterine Sarcomas Reveals Clinically Relevant Molecular Subtypes
  • 2019
  • Ingår i: Clinical Cancer Research. - : AMER ASSOC CANCER RESEARCH. - 1078-0432 .- 1557-3265. ; 25:7, s. 2155-2165
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: Undifferentiated uterine sarcomas (UUS) are rare, extremely deadly, sarcomas with no effective treatment. The goal of this study was to identify novel intrinsic molecular UUS subtypes using integrated clinical, histopathologic, and molecular evaluation of a large, fully annotated, patient cohort.Experimental Design: Fifty cases of UUS with full clinicopathologic annotation were analyzed for gene expression (n = 50), copy-number variation (CNV, n = 40), cell morphometry (n = 39), and protein expression (n = 22). Gene ontology and network enrichment analysis were used to relate over-and underexpressed genes to pathways and further to clinicopathologic and phenotypic findings.Results: Gene expression identified four distinct groups of tumors, which varied in their clinicopathologic parameters. Gene ontology analysis revealed differential activation of pathways related to genital tract development, extracellular matrix (ECM), muscle function, and proliferation. A multivariable, adjusted Cox proportional hazard model demonstrated that RNA group, mitotic index, and hormone receptor expression influence patient overall survival (OS). CNV arrays revealed characteristic chromosomal changes for each group. Morphometry demonstrated that the ECM group, the most aggressive, exhibited a decreased cell density and increased nuclear area. A cell density cutoff of 4,300 tumor cells per mm(2) could separate ECM tumors from the remaining cases with a sensitivity of 83% and a specificity of 94%. IHC staining of MMP-14, Collagens 1 and 6, and Fibronectin proteins revealed differential expression of these ECM-related proteins, identifying potential new biomarkers for this aggressive sarcoma subgroup. Conclusions: Molecular evaluation of UUS provides novel insights into the biology, prognosis, phenotype, and possible treatment of these tumors.

  • Lack of association of CCR2-64I and CCR5-Delta 32 with type 1 diabetes and latent autoimmune diabetes in adults
  • 2003
  • Ingår i: Human Immunology. - 0198-8859 .- 1879-1166. ; 64:6, s. 629-632
  • Tidskriftsartikel (refereegranskat)abstract
    • It is well known that type I diabetes mellitus (T1DM) is a complex genetic disease resulting from the autoimmune destruction of pancreatic beta cells. Several genes have been associated with susceptibility and/or protection for T1DM, but the disease risk is mostly influenced by genes located in the class II region of the major histocompatibility complex. The attraction of leukocytes to tissues is essential for inflammation and the beginning of autoimmune reaction. The process is controlled by chemokines, which are chemotactic cytolines. Some studies have shown that CCR2-64I and CCR5-Delta32 might be important for protection of susceptibility to some immunologically-mediated disorders. In the present study, we demonstrate the lack of association between CCR2-64I and CCR5-Delta32 gene polymorphism and TIDM and we desrcibe a new method for a simple and more precise genotyping of the CCR2 gene.

  • Swedish norms for the Strengths and Difficulties Questionnaire for children 3-5 years rated by parents and preschool teachers
  • 2020
  • Ingår i: Scandinavian Journal of Psychology. - 0036-5564 .- 1467-9450. ; 61:2, s. 253-261
  • Tidskriftsartikel (refereegranskat)abstract
    • The Strengths and Difficulties Questionnaire (SDQ) is a widespread tool for assessing behavior problems in children and adolescents. Despite being investigated thoroughly concerning both validity and reliability, peer reviewed studies that provide norms, especially for preschool children, are lacking. This paper provides Swedish norms using data from a large community sample of children aged 3-5, based on mothers', fathers', and preschool teacher's ratings. Preschool teachers' ratings were generally lower than parents' ratings, which contradicts some previous studies. Differences between girls and boys were found, suggesting that boys display higher levels of behavior problems. Lower parental education and country of origin outside of Sweden were also associated with more difficulties. Cut-offs are presented for each age group, gender and rater category. Population-specific norms and percentile cut-offs provided in this study facilitate identifying children in need of interventions in paediatric care and enable cross-country comparisons of children's mental health problems.

  • Psychometric properties of the Eating Disorders in Obesity questionnaire : Validating against the Eating Disorder Examination interview
  • 2007
  • Ingår i: Eating and Weight Disorders. - : Editrice Kurtis s.r.l.. - 1124-4909 .- 1590-1262. ; 12:4, s. 168-175
  • Tidskriftsartikel (refereegranskat)abstract
    • Inconclusive results of how weight-loss treatment (WLT) results are affected by participants' eating disorders and/or binge eating are partly due to the variation caused by the multitude of assessment instruments used. The objective of the present study was to evaluate the psychometric properties of a short DSM-IV-based assessment instrument designed to be used specifically in WLT settings, the Eating Disorders in Obesity (EDO) questionnaire. Participants were 97 patients seeking WLT at four surgical and one non-surgical clinics. Participants were assessed by the EDO and the Eating Disorder Examination (EDE) interview . The validity and reliability of the EDO was measured as concordance with the EDE, and test-retest agreement of the EDO, respectively. Validity as well as reliability was found to be good for both eating disorders diagnoses and binge eating as a distinct symptom. Results suggest that the EDO is a short, easily administered instrument with good psychometric properties which makes it a suitable, economical method of assessing eating disorders and binge eating in clinical WLT settings. ©2007, Editrice Kurtis.

  • Motivational Interviewing to Prevent Childhood Obesity: A Cluster RCT
  • 2016
  • Ingår i: Pediatrics. - 0031-4005 .- 1098-4275. ; 137:5
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The objective was to evaluate a manualized theory-driven primary preventive intervention aimed at early childhood obesity. The intervention was embedded in Swedish child health services, starting when eligible children were 9 to 10 months of age and continuing until the children reached age 4. METHODS: Child health care centers in 8 Swedish counties were randomized into intervention and control units and included 1355 families with 1369 infants. Over similar to 39 months, families in the intervention group participated in 1 group session and 8 individual sessions with a nurse trained in motivational interviewing, focusing on healthy food habits and physical activity. Families in the control group received care as usual. Primary outcomes were children's BMI, overweight prevalence, and waist circumference at age 4. Secondary outcomes were children's and mothers' food and physical activity habits and mothers' anthropometrics. Effects were assessed in linear and log-binominal regression models using generalized estimating equations. RESULTS: There were no statistically significant differences in children's BMI (beta = -0.11, 95% confidence interval [CI]: -0.31 to 0.08), waist circumference (beta = -0.48, 95% CI: -0.99 to 0.04), and prevalence of overweight (relative risk = 0.95, 95% CI: 0.69 to 1.32). No significant intervention effects were observed in mothers' anthropometric data or regarding mothers' and children's physical activity habits. There was a small intervention effect in terms of healthier food habits among children and mothers. CONCLUSIONS: There were no significant group differences in children's and mothers' anthropometric data and physical activity habits. There was, however, some evidence suggesting healthier food habits, but this should be interpreted with caution.

  • Cost-Effectiveness of Acceptance and Commitment Therapy and a Workplace Intervention for Employees on Sickness Absence due to Mental Disorders.
  • 2017
  • Ingår i: Journal of Occupational and Environmental Medicine. - 1076-2752 .- 1536-5948. ; 59:12, s. 1211-1220
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The aim of this study was to evaluate cost-effectiveness of Acceptance and Commitment Therapy (ACT) and workplace dialogue intervention (WDI), both as stand-alone interventions and in combination, compared with treatment as usual (TAU), for employees on sickness absence with mental disorders.METHODS: Employees (n = 352, 78.4% females) on sickness absence were randomized to one of four groups. Cost-utility analyses were conducted from a health care perspective and a limited societal perspective.RESULTS: All groups reported significant improvements in health-related quality-of-life (HRQoL) and there were no significant differences in HRQoL or costs between groups. The probability of cost-effectiveness for ACT+WDI was 50% compared with ACT, indicating that both treatment alternatives could be considered equally favorable for decision-makers. TAU and WDI were rejected due to less economic efficiency.CONCLUSION: Adding WDI to ACT cannot be recommended on the basis of our study results.
