  • A new highly penetrant form of obesity due to deletions on chromosome 16p11.2.
  • 2010
  • In: Nature. - : Springer Science and Business Media LLC. - 1476-4687 .- 0028-0836. ; 463:7281, s. 671-5
  • Journal article (peer-reviewed)abstract
    • Obesity has become a major worldwide challenge to public health, owing to an interaction between the Western 'obesogenic' environment and a strong genetic contribution. Recent extensive genome-wide association studies (GWASs) have identified numerous single nucleotide polymorphisms associated with obesity, but these loci together account for only a small fraction of the known heritable component. Thus, the 'common disease, common variant' hypothesis is increasingly coming under challenge. Here we report a highly penetrant form of obesity, initially observed in 31 subjects who were heterozygous for deletions of at least 593 kilobases at 16p11.2 and whose ascertainment included cognitive deficits. Nineteen similar deletions were identified from GWAS data in 16,053 individuals from eight European cohorts. These deletions were absent from healthy non-obese controls and accounted for 0.7% of our morbid obesity cases (body mass index (BMI) >or= 40 kg m(-2) or BMI standard deviation score >or= 4; P = 6.4 x 10(-8), odds ratio 43.0), demonstrating the potential importance in common disease of rare variants with strong effects. This highlights a promising strategy for identifying missing heritability in obesity and other complex traits: cohorts with extreme phenotypes are likely to be enriched for rare variants, thereby improving power for their discovery. Subsequent analysis of the loci so identified may well reveal additional rare variants that further contribute to the missing heritability, as recently reported for SIM1 (ref. 3). The most productive approach may therefore be to combine the 'power of the extreme' in small, well-phenotyped cohorts, with targeted follow-up in case-control and population cohorts.

  • Low copy number of the salivary amylase gene predisposes to obesity
  • 2014
  • In: Nature Genetics. - : Nature Publishing Group. - 1061-4036 .- 1546-1718. ; 46:5, s. 492-497
  • Journal article (peer-reviewed)abstract
    • Common multi-allelic copy number variants (CNVs) appear enriched for phenotypic associations compared to their biallelic counterparts. Here we investigated the influence of gene dosage effects on adiposity through a CNV association study of gene expression levels in adipose tissue. We identified significant association of a multi-allelic CNV encompassing the salivary amylase gene (AMY1) with body mass index (BMI) and obesity, and we replicated this finding in 6,200 subjects. Increased AMY1 copy number was positively associated with both amylase gene expression (P = 2.31 × 10-14) and serum enzyme levels (P < 2.20 × 10-16), whereas reduced AMY1 copy number was associated with increased BMI (change in BMI per estimated copy =-0.15 (0.02) kg/m 2; P = 6.93 × 10-10) and obesity risk (odds ratio (OR) per estimated copy = 1.19, 95% confidence interval (CI) = 1.13-1.26; P = 1.46 × 10-10). The OR value of 1.19 per copy of AMY1 translates into about an eightfold difference in risk of obesity between subjects in the top (copy number > 9) and bottom (copy number < 4) 10% of the copy number distribution. Our study provides a first genetic link between carbohydrate metabolism and BMI and demonstrates the power of integrated genomic approaches beyond genome-wide association studies. © 2014 Nature America, Inc.

  • Folate and vitamin B-12 concentrations are associated with plasma DHA and EPA fatty acids in European adolescents : the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study
  • 2017
  • In: British Journal of Nutrition. - : CAMBRIDGE UNIV PRESS. - 0007-1145 .- 1475-2662. ; 117:1, s. 124-133
  • Journal article (peer-reviewed)abstract
    • This study aimed to examine the association between vitamin B-6, folate and vitamin B-12 biomarkers and plasma fatty acids in European adolescents. A subsample from the Healthy Lifestyle in Europe by Nutrition in Adolescence study with valid data on B-vitamins and fatty acid blood parameters, and all the other covariates used in the analyses such as BMI, Diet Quality Index, education of the mother and physical activity assessed by a questionnaire, was selected resulting in 674 cases (43% males). B-vitamin biomarkers were measured by chromatography and immunoassay and fatty acids by enzymatic analyses. Linear mixed models elucidated the association between B-vitamins and fatty acid blood parameters (changes in fatty acid profiles according to change in 10 units of vitamin B biomarkers). DHA, EPA) and n-3 fatty acids showed positive associations with B-vitamin biomarkers, mainly with those corresponding to folate and vitamin B12. Contrarily, negative associations were found with n-6: n-3 ratio, trans-fatty acids and oleic: stearic ratio. With total homocysteine (tHcy), all the associations found with these parameters were opposite (for instance, an increase of 10 nmol/l in red blood cell folate or holotranscobalamin in females produces an increase of 15.85 mu mol/l of EPA (P value < 0.01), whereas an increase of 10 nmol/l of tHcy in males produces a decrease of 2.06 mu mol/l of DHA (P value < 0.05). Positive associations between B-vitamins and specific fatty acids might suggest underlying mechanisms between B-vitamins and CVD and it is worth the attention of public health policies.

  • Intake and dietary sources of haem and non-haem iron among European adolescents and their association with iron status and different lifestyle and socio-economic factors
  • 2013
  • In: European Journal of Clinical Nutrition. - : Springer Science and Business Media LLC. - 0954-3007 .- 1476-5640. ; 67:7, s. 765-772
  • Journal article (peer-reviewed)abstract
    • Background/Objectives:Adolescents are at risk of iron deficiency because of their high iron requirements. The aims of this study were: (1) to assess iron intake, its determinants and its most important food sources and; (2) to evaluate the relation of iron intake and status in European adolescents. Subjects/Methods:Two non-consecutive 24-h recalls were completed by a computerised tool. The socio-demographic and socio-economic data were collected by a self-reported questionnaire. Weight and height were measured. A distinction was made between haem and non-haem iron.Results:The total iron intake was significantly higher among boys (13.8 mg/day; n=1077) than girls (11.0 mg/day; n=1253). About 97.3% of the boys and 87.8% of the girls met the estimated average requirement, and 72.4% of the boys and 13.7% of the girls met the recommendation for bio-available iron intake. The ratio of haem/non-haem iron intake was lower for girls than boys. Meat (19.2; 76%) and bread and rolls (12.6;3.9%) contributed most to total and haem iron intake. Bread and rolls (13.8%) and meat (10.8%) contributed most to non-haem iron intake. Age, sex and body mass index were associated with iron intake. Only red blood cell concentration was significantly negatively associated with total, haem and non-haem iron intake.Conclusion:Girls had lower iron intakes and ratio of haem/non-haem iron intake than boys. The main total iron and haem iron source was meat, while the main non-haem iron source was bread and rolls. Adolescent girls may be a group at risk for iron deficiency. Consequently, special attention and strategies are needed in order to improve iron intakes during adolescence.

  • Nitric oxide pathway-related gene alterations in inflammatory bowel disease
  • 2012
  • In: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 47:11, s. 1283-1297
  • Journal article (peer-reviewed)abstract
    • Objective: To reveal specific gene activation in nitric oxide (NO)-related inflammation we studied differential gene expression in inflammatory bowel disease (IBD). Methods. Total RNA was isolated from 20 biopsies of inflamed mucosa from Crohn's disease (CD) and ulcerative colitis (UC) patients each as well as from six controls, labeled with 32P-dCTP and hybridized to a human NO gene array. Significant genes were analyzed for functional gene interactions and heatmaps generated by hierarchical clustering. A selection of differentially expressed genes was further evaluated with immunohistochemical staining. Results. Significant gene expression differences were found for 19 genes in CD and 23 genes in UC compared to controls, both diseases with high expression of ICAM1 and IL-8. Correlation between microarray expression and corresponding protein expression was significant (r 0.47, p 0.002). Clustering analysis together with functional gene interaction analysis revealed clusters of coregulation and coexpression in CD and UC: transcripts involved in angiogenesis, inflammatory response mediated by the transcription factor hypoxia-inducible factor 1, and tissue fibrosis. Also, a fourth cluster with transcripts regulated by the transcription factor Sp1 was found in UC. Conclusions. Expression analysis in CD and UC revealed disease-specific regulation of NO-related genes, which might be involved in perpetuating inflammatory disease activity in IBD.

  • Profile of physical activity behaviors among Swedish women aged 56-75 years.
  • 2008
  • In: Scandinavian Journal of Medicine and Science in Sports. - : Wiley. - 0905-7188 .- 1600-0838. ; 18:1, s. 95-101
  • Journal article (peer-reviewed)abstract
    • The aim of this study was to assess profiles of physical activity (PA) behavior using accelerometers among middle-aged and elderly women in free-living conditions. A subset of 133 women aged 56-75 years from the population-based Swedish Mammography Cohort with valid accelerometer data was included in the analysis. The proportion of women who met the PA recommendation of accumulating 30 min of moderate-to-vigorous physical activity (MVPA), in either one continuous bout or several shorter bouts lasting 8-10 min, on five or more days/week was 31%. The precision of mean daily estimates of MVPA and of inactivity based on 7 days monitoring was 0.80 and 0.86, respectively. On average, participants spent 103 min/day on MVPA, but only about a third of that time was accumulated in the recommended pattern of bouts lasting at least 8-10 min. Obese women had, on average, one bout of MVPA less than normal-weight women (mean 3.6 bouts/day). The mean MVPA decreased 10 min/day with every 5-year increase in age. A low proportion of women accumulated MVPA in the pattern recommended for health benefits. The proportion would increase considerably if women maintained their current amount of MVPA but increased the duration of each bout of MVPA.

  • Improved Emittance and Brightness for the MAX IV 3 GeV Storage Ring
  • 2022
  • In: Proc. IPAC'22. - 9783954502271 ; , s. 288-291
  • Conference paper (other academic/artistic)abstract
    • At MAX IV Laboratory, the Swedish Synchrotron Radiation (SR) facility, the largest of two rings operates at 3 GeV with a bare lattice emittance of 330 pm rad. Upgrade plans are under consideration aiming at a gradual reduction of the emittance, in three stages: a short-term with an emittance reduction of 20% to 40%, a mid-term with an emittance reduction of more than 50% and a long-term with an emittance in the range of the diffraction limit for hard X-rays (10 keV). In this paper we focus on the short-term case, resuming previous work on a proposed lattice that can reach 270 pm rad emittance, with only minor modifications to the gradients of the magnets of the present ring, i.e. without any hardware changes and all within the present power supply limits. Linear lattice characterisation and calculations of key performance parameters, such as dynamic aperture and momentum aperture with errors, are described and compared to the present operating lattice. Experimental tests of injection into this lattice are also shown.

  • Congestion road tax and physical activity
  • 2010
  • In: American Journal of Preventive Medicine. - : Elsevier BV. - 0749-3797 .- 1873-2607. ; 38:2, s. 171-177
  • Journal article (peer-reviewed)abstract
    • BACKGROUND: Large-scale policy and environmental changes, such as congestion road taxes, may be a way to promote active transportation. PURPOSE: This study aimed to examine the potential effect of a congestion road tax on physical activity. METHODS: Baseline data were collected during October-November 2003, follow-up data in May 2006, and analysis was performed in September 2008. The short self-administered version of the International Physical Activity Questionnaire was used to assess physical activity. Data from those with access to motorized vehicles in the Stockholm region (n=165), where the tax was in place, were compared with those from the Goteborg/Malmo regions (n=138). Within each region before and during the road tax implementation, the data were analyzed for differences in time spent at different intensity levels of physical activity, in addition to sitting, as well as for changes in reported time in overall (weighted) physical activity. RESULTS: There were no significant differences in the magnitude of the changes of the intensity levels of physical activity, weighted overall physical activity, or sitting, between Stockholm and Goteborg/Malmo. Among those exposed to the congestion road tax and with access to motorized vehicles, an increase in moderate physical activity (p=0.036); overall physical activity (p=0.015); and a reduction in time spent sitting (p=0.009) was observed. No differences were observed among those unexposed. CONCLUSIONS: The results from this study on the influence of a congestion road tax on levels of physical activity, though inconclusive, suggest that policy changes such as a congestion road tax might promote improvements in physical activity levels in individuals with motorized vehicles.

  • Adiponectin and bariatric surgery: Associations with diabetes and cardiovascular disease in the Swedish obese subjects study
  • 2014
  • In: Diabetes Care. - : American Diabetes Association Inc.. - 0149-5992 .- 1935-5548. ; 37:5, s. 1401-1409
  • Journal article (peer-reviewed)abstract
    • OBJECTIVE: Adiponectin has been implicated in the pathogenesis of type 2 diabetes, but its role for incident diabetes, myocardial infarction, or stroke in obesity is unclear. The aim of this study was to analyze the associations between systemic levels of adiponectin and the aforementioned outcomes in a population with severe obesity at high risk of diabetes and cardiovascular events. RESEARCH DESIGN AND METHODS: We measured serum concentrations of total adiponectin in 3,299 participants of the prospective controlled Swedish Obese Subjects (SOS) Study (bariatric surgery group, n = 1,570; control group given usual care, n = 1,729). Median follow-up periods ranged between 10 and 13 years for different outcomes. RESULTS: In models containing both baseline adiponectin and 2-year changes in adiponectin, high baseline adiponectin and 2-year increases in adiponectin were associated with decreased risk of diabetes and myocardial infarction among controls. In the surgery group, the 2-year weight loss was paralleled by substantial increase in circulating adiponectin (1,807-1,958 ng/mL per 10-kg weight loss). However, neither baseline adiponectin nor 2-year increases in adiponectin were associated with risk of diabetes or myocardial infarction in the fully adjusted models in the surgery group. No associations were found for stroke in either group. CONCLUSIONS: Taken together, baseline adiponectin and 2-year changes were associated with incident diabetes and myocardial infarction in the control group but not in the surgery group. Baseline adiponectin did not predict treatment benefit of bariatric surgery. © 2014 by the American Diabetes Association.

  • Novel association approach for variable number tandem repeats (VNTRs) identifies DOCK5 as a susceptibility gene for severe obesity
  • 2012
  • In: Human Molecular Genetics. - : Oxford University Press (OUP). - 0964-6906 .- 1460-2083. ; 21:16, s. 3727-3738
  • Journal article (peer-reviewed)abstract
    • Variable number tandem repeats (VNTRs) constitute a relatively under-examined class of genomic variants in the context of complex disease because of their sequence complexity and the challenges in assaying them. Recent large-scale genome-wide copy number variant mapping and association efforts have highlighted the need for improved methodology for association studies using these complex polymorphisms. Here we describe the in-depth investigation of a complex region on chromosome 8p21.2 encompassing the dedicator of cytokinesis 5 (DOCK5) gene. The region includes two VNTRs of complex sequence composition which flank a common 3975 bp deletion, all three of which were genotyped by polymerase chain reaction and fragment analysis in a total of 2744 subjects. We have developed a novel VNTR association method named VNTRtest, suitable for association analysis of multi-allelic loci with binary and quantitative outcomes, and have used this approach to show significant association of the DOCK5 VNTRs with childhood and adult severe obesity (P-empirical 8.9 10(8) and P 3.1 10(3), respectively) which we estimate explains approximate to 0.8 of the phenotypic variance. We also identified an independent association between the 3975 base pair (bp) deletion and obesity, explaining a further 0.46 of the variance (P-combined 1.6 10(3)). Evidence for association between DOCK5 transcript levels and the 3975 bp deletion (P 0.027) and both VNTRs (P-empirical 0.015) was also identified in adipose tissue from a Swedish family sample, providing support for a functional effect of the DOCK5 deletion and VNTRs. These findings highlight the potential role of DOCK5 in human obesity and illustrate a novel approach for analysis of the contribution of VNTRs to disease susceptibility through association studies.

  • Lunch at school, at home or elsewhere : Where do adolescents usually get it and what do they eat? Results of the HELENA study
  • 2013
  • In: Appetite. - : Elsevier BV. - 0195-6663 .- 1095-8304. ; 71, s. 332-339
  • Journal article (peer-reviewed)abstract
    • Considering the lack of uniformity regarding school meals in Europe, information on adolescents' school lunch patterns is of public health importance. Thus, the aim of this analysis was to describe and evaluate lunchtime energy and food intake of European adolescents at different lunch locations. Data on nutritional and health-related parameters were derived from the HEalthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study (HELENA-CSS). A sub-sample of 891 adolescents (47% male) with plausible data on total and lunchtime energy intake (2. ×. 24. h recall) as well as usual lunch location was considered. Food intake was compared to lunch of the Optimized Mixed Diet (OMD) for children and adolescents. Although energy intake was nearly in line with the recommendations, food intake was suboptimal compared to the OMD regardless of usual lunch location. Adolescents had more potatoes and less sweets at school, and more drinks (water, coffee and tea) and vegetables at home when each compared with the other locations. Food intake of adolescents getting their lunch elsewhere was characterized by the smallest amounts of potatoes and the highest amounts of sweets. Although lunch patterns may differ among countries, schools in Europe do not seem to reveal all their potential to offer access to a healthy lunch for adolescents yet.

  • In: Proceedings of the International Beam Instrumentation Conference, IBIC. - 9783954502417 ; , s. 335-338
  • Conference paper (peer-reviewed)abstract
    • Feedforward control loops are used in numerous applications to correct process variables. While feedforward control loops correct process variables according to the expected behavior of a system at any given setpoint, feedback loops require measurements of the output to correct deviations from the setpoint. At MAX IV, a generic multi-dimensional input and output feedforward controller was implemented using TANGO Control System. This paper describes the development and use cases of this controller for beam orbit and optics corrections at MAX IV.

  • In: International Journal of Obesity. - : Springer Science and Business Media LLC. - 1476-5497 .- 0307-0565. ; 36:1, s. 137-147
  • Journal article (peer-reviewed)abstract
    • Objective:To use a unique obesity-discordant sib-pair study design to combine differential expression analysis, expression quantitative trait loci (eQTLs) mapping and a coexpression regulatory network approach in subcutaneous human adipose tissue to identify genes relevant to the obese state.Study design:Genome-wide transcript expression in subcutaneous human adipose tissue was measured using Affymetrix U133 Plus 2.0 microarrays (Affymetrix, Santa Clara, CA, USA), and genome-wide genotyping data was obtained using an Applied Biosystems (Applied Biosystems; Life Technologies, Carlsbad, CA, USA) SNPlex linkage panel.Subjects:A total of 154 Swedish families ascertained through an obese proband (body mass index (BMI) >30kgm(-2)) with a discordant sibling (BMI>10kgm(-2) less than proband).Results:Approximately one-third of the transcripts were differentially expressed between lean and obese siblings. The cellular adhesion molecules (CAMs) KEGG grouping contained the largest number of differentially expressed genes under cis-acting genetic control. By using a novel approach to contrast CAMs coexpression networks between lean and obese siblings, a subset of differentially regulated genes was identified, with the previously GWAS obesity-associated neuronal growth regulator 1 (NEGR1) as a central hub. Independent analysis using mouse data demonstrated that this finding of NEGR1 is conserved across species.Conclusion:Our data suggest that in addition to its reported role in the brain, NEGR1 is also expressed in subcutaneous adipose tissue and acts as a central 'hub' in an obesity-related transcript network.

  • Helicobacter pylori adapts to chronic infection and gastric disease via ph-responsive baba-mediated adherence
  • 2017
  • In: Cell Host and Microbe. - : Elsevier BV. - 1931-3128 .- 1934-6069. ; 21:3, s. 376-389
  • Journal article (peer-reviewed)abstract
    • The BabA adhesin mediates high-affinity binding of Helicobacter pylori to the ABO blood group antigen-glycosylated gastric mucosa. Here we show that BabA is acid responsive-binding is reduced at low pH and restored by acid neutralization. Acid responsiveness differs among strains; often correlates with different intragastric regions and evolves during chronic infection and disease progression; and depends on pH sensor sequences in BabA and on pH reversible formation of high-affinity binding BabA multimers. We propose that BabA's extraordinary reversible acid responsiveness enables tight mucosal bacterial adherence while also allowing an effective escape from epithelial cells and mucus that are shed into the acidic bactericidal lumen and that bio-selection and changes in BabA binding properties through mutation and recombination with babA-related genes are selected by differences among individuals and by changes in gastric acidity over time. These processes generate diverse H. pylori subpopulations, in which BabA's adaptive evolution contributes to H. pylori persistence and overt gastric disease.

  • A New Class of Labile Surfactants that Break Down to Non-surface Active Products upon Heating or after a Pre-set Time, without the Need for a pH Change
  • 2007
  • In: Tenside Surfactants Detergents. - : Walter de Gruyter GmbH. - 0932-3414 .- 2195-8564. ; 44:6, s. 366-372
  • Journal article (peer-reviewed)abstract
    • A new class of labile surfactants that break down at a controllable rate without the need for a change in pH will be presented. The invention has been patented by YKI Institute for Surface Chemistry, and is based on use of β-keto acids or their salts as surface-active compounds. These surfactants spontaneously break down through decarboxylation, to form an oil-like ketone and CO 2/HCO 3 -/CO 32 - depending on pH. The rate of breakdown can be controlled within a wide range by temperature or by certain additives, but, unlike most cleavable surfactants, a change in pH is not needed. Furthermore the surfactants can be conveniently activated from a stabile precursor just before use, and one (of many possible) precursors of this kind is already available on the industrial scale in the form of a wellknown chemical that is FDA-approved in other, non-surfactant, applications. The compound in question, alkyl ketene dimer (AKD), is produced in large scale by a number of large chemical producers today, and used for hydrophobization of paper. The present article gives an overview of the surfactant chemistry, with focus on recent studies of the kinetics of activation of the surfactant precursor and breakdown kinetics of the labile surfactant at different conditions. Furthermore, possible industrial applications of the surfactant will be discussed, with one example taken from a recent feasibility study performed within the car washing area. © Carl Hanser Publisher.

  • PNPLA3 I148M (rs738409) genetic variant is associated with hepatocellular carcinoma in obese individuals
  • 2012
  • In: Digestive and Liver Disease. - : Elsevier BV. - 1590-8658. ; 44:12, s. 1037-1041
  • Journal article (peer-reviewed)abstract
    • Background: Obesity is a risk factor for cancer, including hepatocellular carcinoma. Patatin-like phospholipase domain-containing 3 (PNPLA3) I148M (rs738409) genetic variant has been associated with hepatocellular carcinoma (HCC) in individuals with chronic alcohol abuse or hepatic viral infection. In the present study we examined the association between the PNPLA3I148M genetic variant and hepatocellular carcinoma in obese individuals from the Swedish Obese Subjects cohort (n=4047). Methods: We performed a matched, prospective, controlled, interventional trial, investigating the effect of bariatric surgery (surgery group) compared to conventional treatment (control group) for obesity. Results: A total of 9 events were observed in the 15-year median follow up (5 in the control group and 4 in the surgery group). A significantly higher incidence of hepatocellular carcinoma in PNPLA3 148M allele carriers was found in obese individuals in the control group (log-rank P-value=0.001), but not in the surgery group (log-rank P-value=0.783). Consistently, an increased risk (for each PNPLA3 148M allele, hazard ratio: 5.9; 95% confidence interval 1.5-23.8; P-value=0.013) of developing hepatocellular carcinoma was observed only in the control group. Conclusion: The current study is the first prospective report showing the association of the PNPLA3I148M genetic variant and hepatocellular carcinoma in severely obese individuals.
