- BackgroundOur aim was to investigate the factors that affect health related quality of life (HRQL) in adult Swedish food allergic patients objectively diagnosed with allergy to at least one of the staple foods cow’s milk, hen’s egg or wheat. The number of foods involved, the type and severity of symptoms, as well as concomitant allergic disorders were assessed.MethodsThe disease-specific food allergy quality of life questionnaire (FAQLQ-AF), developed within EuroPrevall, was utilized. The questionnaire had four domains: Allergen Avoidance and Dietary Restrictions (AADR), Emotional Impact (EI), Risk of Accidental Exposure (RAE) and Food Allergy related Health (FAH). Comparisons were made with the outcome of the generic questionnaire EuroQol Health Questionnaire, 5 Dimensions (EQ-5D). The patients were recruited at an outpatient allergy clinic, based on a convincing history of food allergy supplemented by analysis of specific IgE to the foods in question. Seventy-nine patients participated (28 males, 51 females, mean-age 41 years).ResultsThe domain with the most negative impact on HRQL was AADR, assessing the patients’ experience of dietary restrictions. The domain with the least negative impact on HRQL was FAH, relating to health concerns due to the food allergy. One third of the patients had four concomitant allergic disorders, which had a negative impact on HRQL. Furthermore, asthma in combination with food allergy had a strong impact. Anaphylaxis, and particularly prescription of an epinephrine auto-injector, was associated with low HRQL. These effects were not seen using EQ-5D. Analyses of the symptoms revealed that oral allergy syndrome and cardiovascular symptoms had the greatest impact on HRQL. In contrast, no significant effect on HRQL was seen by the number of food allergies.ConclusionsThe FAQLQ-AF is a valid instrument, and more accurate among patients with allergy to staple foods in comparison to the commonly used generic EQ-5D. It adds important information on HRQL in food allergic adults. We found that the restrictions imposed on the patients due to the diet had the largest negative impact on HRQL. Both severity of the food allergy and the presence of concomitant allergic disorders had a profound impact on HRQL.

- Få studier av kostnader för allergisjukdomar är genomförda nationellt och internationellt. I Sverige är det endast astma som är studerat, och för rinit och eksem finns endast ett fåtal internationella studier. Inom födoämnesöverkänslighet finns över huvud taget inga sjukdomskostnadsstudier publicerade. Det är svårt att jämföra olika studier, såväl nationellt som internationellt, på grund av olika studiedesign, hälso- och sjukvårdssystem och behandlingstraditioner. De svenska kostnaderna för de studerade allergisjukdomarna har skattats och uppgår sannolikt till över 10 miljarder kronor totalt per år, varav kostnaden för astma uppgår till cirka 7 miljarder kronor. Det är viktigt att studier kommer till stånd i Sverige för att få en uppfattning om de faktiska svenska kostnaderna för allergisjukdomarna.

- Leptin is an adipocyte-secreted hormone, the circulating levels of which correlate closely with overall adiposity. Although rare mutations in the leptin (LEP) gene are well known to cause leptin deficiency and severe obesity, no common loci regulating circulating leptin levels have been uncovered. Therefore, we performed a genome-wide association study (GWAS) of circulating leptin levels from 32,161 individuals and followed up loci reaching P<10(-6) in 19,979 additional individuals. We identify five loci robustly associated (P<5 × 10(-8)) with leptin levels in/near LEP, SLC32A1, GCKR, CCNL1 and FTO. Although the association of the FTO obesity locus with leptin levels is abolished by adjustment for BMI, associations of the four other loci are independent of adiposity. The GCKR locus was found associated with multiple metabolic traits in previous GWAS and the CCNL1 locus with birth weight. Knockdown experiments in mouse adipose tissue explants show convincing evidence for adipogenin, a regulator of adipocyte differentiation, as the novel causal gene in the SLC32A1 locus influencing leptin levels. Our findings provide novel insights into the regulation of leptin production by adipose tissue and open new avenues for examining the influence of variation in leptin levels on adiposity and metabolic health.

- The Radio and Plasma Waves (RPW) instrument on the ESA Solar Orbiter mission is described in this paper. This instrument is designed to measure in-situ magnetic and electric fields and waves from the continuous to a few hundreds of kHz. RPW will also observe solar radio emissions up to 16 MHz. The RPW instrument is of primary importance to the Solar Orbiter mission and science requirements since it is essential to answer three of the four mission overarching science objectives. In addition RPW will exchange on-board data with the other in-situ instruments in order to process algorithms for interplanetary shocks and type III langmuir waves detections.

- BACKGROUND: We previously reported that indirect and intangible costs burden households with a food allergic adult. We now extend our investigation to households with food allergic children and adolescents. OBJECTIVE: The objective of this study was to estimate direct, indirect, and intangible costs of food allergy in households with a child and/or adolescent with objectively diagnosed allergy to staple foods (cow's milk, hen's egg, and/or wheat), and to compare these costs with age-and sex-matched controls. METHODS: Direct and indirect cost parent-reported data collected via the Food Allergy Socio-Economic Questionnaire of 84 children (0-12 years) and 60 adolescents (13-17 years) with objectively diagnosed allergy to staple foods ("cases") and age- and sex-matched controls (n = 94 children; n = 56 adolescents) were compared. Annual household costs were calculated. Total household costs included direct plus indirect costs. Intangible costs included parent-reported health of their child and/or adolescent, standard of living, and perceptions of well-being. RESULTS: Amongst cases, total household costs were higher by (sic)3961 for children and (sic)4792 for adolescents versus controls (P < .05), and were driven by direct (eg, medications) and indirect (eg, time with health care professionals) costs. For children only, a history of anaphylaxis was associated with higher direct costs than no anaphylaxis ((sic)13,016 vs (sic)10,044, P < .05). Intangible costs (eg, parent-reported health of a child and/or adolescent) were significantly impacted amongst cases versus controls (P < .01). CONCLUSION: Households with a child and/or adolescent with objectively diagnosed allergy to staple foods have higher total household costs than controls. Direct and indirect costs were significantly higher for cases versus controls amongst children only. Amongst both age groups, such allergy adversely impacted intangible costs. (C) 2015 The Authors.

- Background: Cow's milk, hen's egg and wheat are staple foods in a typical western diet. Despite the ubiquity of these foods, the impact of staple food allergy on health-related quality of life (HRQL) amongst adolescents is incompletely understood. The aims of this study were to make use of the Swedish version of EuroPrevall's disease-specific food allergy quality of life questionnaire-teenager form (FAQLQ-TF) and to investigate the association between objectively-diagnosed staple food allergy and HRQL amongst adolescents. Methods: In this cross-sectional study, 58 adolescents aged 13-17 years [n = 40 (69 %) boys] with objectively-diagnosed allergy to the staple foods cow's milk, hen's egg and/or wheat and living in Stockholm, Sweden were included. Adolescents completed the FAQLQ-TF, which has a corresponding scale of 1 = best HRQL, and 7 = worst HRQL. Overall HRQL and domain-specific HRQL were established. Adolescents also reported symptoms, adrenaline auto injector (AAI) prescription and presence of other food allergies. A history of anaphylaxis was defined among those reporting difficulty breathing, inability to stand/collapse, and/or loss of consciousness. Clinically different HRQL was set at a mean difference of >= 0.5. Results: Overall mean HRQL was poorer than average [mean: 4.70/7.00 (95 % CI 4.30-5.01)]. The domain risk of accidental exposure was significantly associated with clinically better HRQL than the domain allergen avoidance and dietary restrictions (mean difference = 0.76; p < 0.001). Girls had clinically worse, but not statistically significantly different mean HRQL than boys (mean difference = 0.71; p < 0.07). HRQL tended to be worse amongst those with allergies to more than three foods or an AAI prescription. The number and types of symptoms, including a history of anaphylaxis were not associated with worse HRQL. Conclusions: As ascertained via a food allergy-specific questionnaire, adolescents with staple food allergy report poorer than average HRQL, specifically in relation to emerging independence and the need for support. Girls have clinically worse HRQL than boys. The number and type of previous symptoms and history of anaphylaxis were not associated with worse HRQL.

Konferensbidrag (refereegranskat)abstract
- I ett sameuropeiskt Leonardo da Vinci-projekt har utvecklats ett internationellt utbildnings- och praktikpa- ket för blivande sjukhusfysiker [1-3]. Utbildningspaketet innehåller praktiska och kliniska övningsuppgifter där delta- garna tränas i för en sjukhusfysiker vanligt förekommande arbetsuppgifter. Målet har varit att det skall ge sjukhusfysi- kern den praktiska kompetens som krävs av det europeiska regelverket inom ämnesområdena magnetresonans (MRI), ultraljud, röntgendiagnostik, nuklearmedicin och strålbe- handling. Utbildningsmaterialet är webbaserat med en stor bilddata- bas och används redan i nära 70 länder runt om i världen. EMIT-projektet (European Medical Imaging Technology Training) belönades i december 2004 med det första Leonar- do da Vinci priset som delades ut till de tre bästa av totalt 4000 EU-projekt inom praktisk yrkesrelaterad utbildning. I projektet har vi konfronterats med den pedagogiska ut- maningen att förmedla praktisk kunskap, i sjukhusmiljöer med mycket olika förutsättningar beroende på vilket land deltagarna arbetar i. En omöjlig uppgift kan tyckas, men eftersom materialet är sammanställt av några av Europas starkaste forsknings- och utbildningsgrupper inom respekti- ve område så har det visat sig vara en stor tillgång och varje användare utnyttjar materialet efter sina egna behov. En an- nan erfarenhet är samarbetet över nationsgränser där vi har utnyttjat och konfronterats med likheter och oliktänkande inte minst vad gäller pedagogik och didaktik. Vi har dessut- om fått ett stort kontaktnät och många goda vänner. Den här presentationen beskriver delar av utbildningspaketet och erfarenheter av samarbetsprojektet.

- OBJECTIVE: Our previous studies suggest that the SNARE protein synaptosomal-associated protein of 23 kDa (SNAP23) is involved in the link between increased lipid levels and insulin resistance in cardiomyocytes. The objective was to determine whether SNAP23 may also be involved in the known association between lipid accumulation in skeletal muscle and insulin resistance/type 2 diabetes in humans, as well as to identify a potential regulator of SNAP23. RESEARCH DESIGN AND METHODS: We analyzed skeletal muscle biopsies from patients with type 2 diabetes and healthy, insulin-sensitive control subjects for expression (mRNA and protein) and intracellular localization (subcellular fractionation and immunohistochemistry) of SNAP23, and for expression of proteins known to interact with SNARE proteins. Insulin resistance was determined by a euglycemic hyperinsulinemic clamp. Potential mechanisms for regulation of SNAP23 were also investigated in the skeletal muscle cell line L6. RESULTS: We showed increased SNAP23 levels in skeletal muscle from patients with type 2 diabetes compared with that from lean control subjects. Moreover, SNAP23 was redistributed from the plasma membrane to the microsomal/cytosolic compartment in the patients with the type 2 diabetes. Expression of the SNARE-interacting protein Munc18c was higher in skeletal muscle from patients with type 2 diabetes. Studies in L6 cells showed that Munc18c promoted the expression of SNAP23. CONCLUSIONS: We have translated our previous in vitro results into humans by showing that there is a change in the distribution of SNAP23 to the interior of the cell in skeletal muscle from patients with type 2 diabetes. We also showed that Munc18c is a potential regulator of SNAP23.
