- Weight loss and physical activity have shown favorable effects on risks associated with obesity. It is therefore of interest to evaluate exercise capacity and related co-morbidities in obese patients. We present data from obese subjects evaluated by the 6-minute walk test (6MWT) before and after a 7.3 (6.1-8.2) month weight reduction program. 251 subjects completed the test at baseline (BMI 40.6 [36.9-44.6] kg/m(2) ) and 129 (51.4 %) repeated the test after intervention (BMI 35.6 [31.2-38.5] kg/m(2) ). The six minute walking distance (6MWD) at baseline (535 [480-580] m) and at follow up (599 [522-640] m) correlated to several cardiovascular risk markers. Age, weight, height, resting heart rate, smoking status, fP-glucose and use of ß-blockers explained 43 % of the variance in predicted 6MWD at baseline. The effect of smoking status, fP-glucose, ß-blockers and resting heart rate lost significance at follow up. Presence of diabetes and the metabolic syndrome had a negative influence on 6MWD but did not affect the impact of intervention based on percentage increase in walking distance. Gender had no impact on 6MWD. Reported pain during the test was common but decreased after intervention (57.0 % vs. 28.7 %, p<0.001). In conclusion, the 6MWT may be used to evaluate intervention success beyond kilogram weight loss in obese subjects. We present formulas to predict 6MWD and the effect of weight loss on walking distance in clinical practice. Pain is a common problem which has to be considered when giving advice on exercise as a part of weight loss intervention.

- Needle-related procedures are reported to be problematic for children. In a school-based celiac disease screening, 12-year-olds' experiences with relaxation and guided imagery (R-GI) during venipuncture were investigated. One group tried nurse-led R-GI (n = 60) and another group received standard care (SC; n = 49). A mixed method design was applied using short written narratives, facial affective scale (FAS), and visual analog scale (VAS) for pain intensity. Qualitative content analysis highlighted that diversity and contradictions when facing blood tests. FAS scores were significantly lower in the SC group before (p = 0.01), during (p = 0.01), and after (p = 0.01) venipuncture. VAS scores did not differ between the groups. The blood test was mostly experienced as unproblematic, and GI during venipuncture did not decrease pain or affect. However, the fact that a number of children scored high FAS indicates a need for effective methods to help children cope with needle-related school-based procedures.

- OBJECTIVES: Between 1984 and 1996, Sweden experienced an "epidemic" of clinical celiac disease in children andlt;2 years of age, attributed partly to changes in infant feeding. Whether infant feeding affects disease occurrence and/or the clinical presentation remains unknown. We investigated and compared the total prevalence of celiac disease in 2 birth cohorts of 12-year-olds and related the findings to each cohorts ascertained infant feeding. less thanbrgreater than less thanbrgreater thanMETHODS: A 2-phase cross-sectional screening study was performed in which 13 279 children from 2 birth cohorts participated: children born during the epidemic (1993) and children born after the epidemic (1997). Previously diagnosed cases were reported and confirmed. Blood samples were analyzed for serological markers and children with positive values were referred for small intestinal biopsy. Infant feeding practices in the cohorts were ascertained via questionnaires. Prevalence comparisons were expressed as prevalence ratios. less thanbrgreater than less thanbrgreater thanRESULTS: The total prevalence of celiac disease was 29 in 1000 and 22 in 1000 for the 1993 and 1997 cohorts, respectively. Children born in 1997 had a significantly lower risk of having celiac disease compared with those born in 1993 (prevalence ratio: 0.75; 95% confidence interval: 0.60-0.93; P = .01). The cohorts differed in infant feeding (specifically, in the proportion of infants introduced to dietary gluten in small amounts during ongoing breastfeeding). less thanbrgreater than less thanbrgreater thanCONCLUSIONS: A significantly reduced prevalence of celiac disease in 12-year-olds indicates an option for disease prevention. Our findings suggest that the present infant feeding recommendation to gradually introduce gluten-containing foods from 4 months of age, preferably during ongoing breastfeeding, is favorable.

- BACKGROUND: Differential gene expression in adipose tissue during diet-induced weight loss followed by a weight stability period is poorly characterized. Markers of these processes may provide a deeper understanding of underlying mechanisms. OBJECTIVE: We aimed to identify differentially expressed genes in human adipose tissue during weight loss and weight maintenance after weight loss. DESIGN: RNA from subcutaneous abdominal adipose tissue from 9 obese subjects was analyzed by using a complementary DNA microarray at baseline after weight loss on a low-calorie diet and after weight maintenance. RESULTS: Subjects lost 18.8 ± 1.8% of weight and maintained this loss during weight maintenance (1.1 ± 2.1%; range: -9.3 to 10.6%). Most differentially expressed genes exhibited a reciprocal regulation and returned to baseline after weight loss (2163 genes) and weight maintenance (3175 genes). CETP and ABCG1, both of which participate in the HDL-mediated reverse cholesterol transport (RCT), were among the most upregulated of the 750 genes that were differentially expressed after both processes. Several genes involved in inflammation were downregulated. The use of real-time polymerase chain reaction confirmed or partially confirmed the previously implicated genes TNMD and MMP9 (both downregulated), PNPLA3 (upregulated), and CIDEA and SCD (both reciprocally regulated). CONCLUSIONS: The beneficial effects of weight loss should be investigated after long-term weight maintenance. The processes of weight loss and weight maintenance should be viewed as biologically distinct. CETP and ABCG1 may be important mediators of these effects through HDL-mediated RCT.

- BACKGROUND: Food habits, nutrient needs and intakes differ between males and females, although few nutritional studies on patients with coeliac disease (CD) have reported results stratified by gender.OBJECTIVES: To compare energy and nutrient intakes among 13-year olds diagnosed with CD in early childhood with those of a non-coeliac (NC) age- and gender-matched control group, and also with estimated average requirements (EAR).METHODS: A case-control study was conducted in Sweden 2006-2007 within the coeliac screening study ETICS (Exploring The Iceberg of Coeliacs in Sweden). Dietary intake was assessed among 37 adolescents (23 girls) diagnosed with CD at median age 1.7 years (CD group) and 805 (430 girls) NC controls (NC group) using a food-frequency questionnaire covering 4 weeks. Reported energy intake was validated by comparison with the calculated physical activity level (PAL).RESULTS: Regardless of CD status, most adolescents reported an intake above EAR for most nutrients. However, both groups had a low intake of vitamin C, with 13% in the CD-group and 25% in the NC-group below EAR, and 21% of boys in the CD-group below EAR for thiamine. The intake of fatty acids was unbalanced, with a high intake of saturated and a low intake of unsaturated fats. Girls and boys in the CD-group had an overall lower nutrient density in reported food intake compared to girls and boys in the NC-group.CONCLUSIONS: Nutrient intake of adolescent girls and boys with CD was mostly comparable to intakes of NC controls. Dietitians should take the opportunity to reinforce a generally healthy diet when providing information about the gluten-free diet.

- A dietary survey was performed during a large screening study in Sweden among 13-year-old adolescents. The aim was to study how the intake of food groups was affected by a screening-detected diagnosis of celiac disease (CD) and its gluten-free (GF) treatment. Food intake, was reported using a food frequency questionnaires (FFQ) and intake reported by the adolescents who was screened to CD was compared with the intake of two same-aged referent groups: i) adolescents diagnosed to CD prior screening and ii) adolescents without CD.. The food intake groups were measured at baseline before the screening-detected cases were aware of their CD, and 12-18 months later.The result showed that the food intakes are affected by a screen detected CD and its dietary treatment. Many flour-based foods were reduced such as pizza, fish fingers, and pastries. The result also indicated that the bread intake was lower before the screened diagnosis compared to the other studied groups, but increased afterwards. Specially manufactured GF-products (e.g. pasta and bread) were frequently used in the screened CDgroup after changing to a GF-diet. Our results suggest that changing to a GF-diet reduces the intake of some popular foods, and the ingredients on the plate are altered, but this do not necessarily include a change of food groups. The availability of manufactured GF-replacement products makes it possible for adolescents to keep many of their old food habits when diagnosed with CD in Sweden.

- Despite advances in anti-platelet treatments, there still exists an early increase in both ischemic as well as bleeding events following primary PCI in patients with ST-elevation myocardial infarction (STEMI). Platelet inhibition data of different anti-platelet treatments in the acute phase of a myocardial infarction might offer some insight into these problems. The aim of this study was to evaluate the pharmacodynamic profile of 5 different anti-platelet treatments in the acute phase of STEMI in patients undergoing primary PCI.

- Background: Type 2 diabetes (T2D) decreases health-related quality of life, but there is a lack of information about the health status of people in pre-diabetic states. However, information on health utility weights (HUWs) for pre-diabetic states and T2D are essential to estimate the effect of prevention initiatives. We estimated and compared HUWs for healthy individuals, those with pre-diabetes and those with T2D in a Swedish population and evaluated the influence of age, sex, education and body mass index on HUWs.Methods: Participants of the Västerbotten Intervention Program, Sweden, between 2002 and 2012, who underwent an oral glucose tolerance test or indicated they had T2D and who filled in the Short Form-36 questionnaire (SF-36) were included. Individuals were categorized as healthy, being in any of three different pre-diabetic states, or as T2D. The pre-diabetic states are impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or a combination of both (IFG&IGT). The SF-6D index was used to convert SF-36 responses to HUWs. HUWswere stratified by age, sex, education and body mass index. Beta regression analyses were conducted to estimate the effect of multiple risk factors on the HUWs.Results: In total, 55 882 individuals were included in the analysis. The overall mean HUW was 0.764. The mean HUW of healthy individuals was 0.768, 0.759 for those with IFG, 0.746 for those with IGT, 0.745 for those with IFG&IGT, and 0.738 for those with T2D. In the overall model, all variables except underweight vs. normal weight were significantly associated with HUW. Younger age, male sex, and higher education were associated with increased HUW. Normal weight, or being overweight was associated with elevated HUW, while obesity was associated with lower HUW.Conclusions: Healthy individuals had higher HUWs than participants with T2D, while individuals with IFG, IGT or IFG&IGT had HUWs that ranged between those for NGT and T2D. Therefore, preventing the development of pre-diabetic states would improve health-related quality of life in addition to lowering the risk of developing T2D.

Tidskriftsartikel (refereegranskat)abstract
- Background: Several studies investigated transitions and risk factors from impaired glucose tolerance (IGT) to type 2 diabetes mellitus (T2D). However, there is a lack of information on the probabilities to transit from normal glucose tolerance (NGT) to different pre-diabetic states and from these states to T2D. The objective of our study is to estimate these risk equations and to quantify the influence of single or combined risk factors on these transition probabilities. Methods: Individuals who participated in the VIP program twice, having the first examination at ages 30, 40 or 50 years of age between 1990 and 1999 and the second examination 10 years later were included in the analysis. Participants were grouped into five groups: NGT, impaired fasting glucose (IFG), IGT, IFG&IGT or T2D. Fourteen potential risk factors for the development of a worse glucose state (pre-diabetes or T2D) were investigated: sex, age, education, perceived health, triglyceride, blood pressure, BMI, smoking, physical activity, snus, alcohol, nutrition and family history. Analysis was conducted in two steps. Firstly, factor analysis was used to find candidate variables; and secondly, logistic regression was employed to quantify the influence of the candidate variables. Bootstrap estimations validated the models. Results: In total, 29 937 individuals were included in the analysis. Alcohol and perceived health were excluded due to the results of the factor analysis and the logistic regression respectively. Six risk equations indicating different impacts of different risk factors on the transition to a worse glucose state were estimated and validated. The impact of each risk factor depended on the starting or ending pre-diabetes state. High levels of triglyceride, hypertension and high BMI were the strongest risk factors to transit to a worsened glucose state. Conclusions: The equations could be used to identify individuals with increased risk to develop any of the three pre-diabetic states or T2D and to adapt prevention strategies.
