- Introduction: The incidence of hyperthyroidism has been reported in various countries to be 23-93/100000 inhabitants per year. This extended study has evaluated the incidence for similar to 40% of the Swedish population of 9 million inhabitants. Sweden is considered to be iodine sufficient country. Methods:All patients including children, who were newly diagnosed with overt hyperthyroidism in the years 2003-2005, were prospectively registered in a multicenter study. The inclusion criteria are as follows:clinical symptoms and/or signs of hyperthyroidism with plasma TSH concentration below 0.2 mIE/l and increased plasma levels of free/total triiodothyronine and/or free/total thyroxine. Patients with relapse of hyperthyroidism or thyroiditis were not included. The diagnosis of Graves' disease (GD), toxic multinodular goiter (TMNG) and solitary toxic adenoma (STA), smoking, initial treatment, occurrence of thyroid-associated eye symptoms/signs, and demographic data were registered. Results:A total of 2916 patients were diagnosed with de novo hyperthyroidism showing the total incidence of 27.6/100 000 inhabitants per year. The incidence of GD was 21.0/100 000 and toxic nodular goiter (TNG=STA+TMNG) occurred in 692 patients, corresponding to an annual incidence of 6.5/100 000. The incidence was higher in women compared with men (4.2:1). Seventy-five percent of the patients were diagnosed with GD, in whom thyroid-associated eye symptoms/signs occurred during diagnosis in every fifth patient. Geographical differences were observed. Conclusion:The incidence of hyperthyroidism in Sweden is in a lower range compared with international reports. Seventy-five percent of patients with hyperthyroidism had GD and 20% of them had thyroid-associated eye symptoms/signs during diagnosis. The observed geographical differences require further studies.

Tidskriftsartikel (refereegranskat)abstract
- Growth hormone deficiency (GHD) in adults is associated with decreased extracellular water volume (ECW). In response to GH replacement therapy (GHRT), ECW increases and blood pressure (BP) reduces or remains unchanged. Our primary aim was to study the association between polymorphisms in genes related to renal tubular function with ECW and BP before and 1 year after GHRT. The ECW measures using bioimpedance analysis (BIA) and bioimpedance spectroscopy (BIS) were validated against a reference method, the sodium bromide dilution method (Br(-)).

- bjective: GH deficiency (GHD) in adults is associated with an altered serum lipid profile that responds to GH replacement therapy (GHRT). This study evaluated the influence of polymorphisms in genes related to lipid metabolism on serum lipid profile before and after 1 year of GHRT in adults. Design and methods: In 318 GHD patients, total cholesterol (TC) serum concentrations, LDL-C, HDL-C, and triglycerides (TG) were assessed. Using a candidate gene approach, 20 single nucleotide polymorphisms (SNPs) were genotyped. GH dose was individually titrated to obtain normal serum IGF1 concentrations. Results: At baseline, the minor alleles of cholesteryl ester transfer protein (CETP) gene SNPs rs708272 and rs1800775 were associated with higher serum TC and apolipoprotein E (APOE) gene SNP rs7412 with lower TC concentrations; CETP SNPs rs708272, rs1800775, and rs3764261 and apolipoprotein B (APOB) gene SNP rs693 with higher serum HDL-C; APOE SNP rs7412, peroxisome proliferator-activated receptor gamma (PPARG) gene SNP rs10865710 with lower LDL-C, and CETP SNP rs1800775 with higher LDL-C; and APOE/C1/C4/C2 cluster SNP rs35136575 with lower serum TG. After treatment, APOB SNP rs676210 GG genotype was associated with larger reductions in TC and LDL-C and PPARG SNP rs10865710 CC genotype with greater TC reduction. All associations remained significant when adjusted for age, sex, and BMI. Conclusions: In GHD adults, multiple SNPs in genes related to lipid metabolism contributed to individual differences in baseline serum lipid profile. The GH treatment response in TC and LDL-C was influenced by polymorphisms in the APOB and PPARG genes.

Nationellt fackspråk för vård och omsorg : Slutrapport
- 2011
-
Rapport (populärvet., debatt m.m.)abstract
- SammanfattningEtt tillgängligt och använt nationellt fackspråk ska bidra till en god och säker vård och omsorg. Det ska även medverka till att kvaliteten och resultaten på området ska kunna följas upp och jämföras på ett mer effektivt sätt. Slutrapporten presenterar resultatet av projektet Nationellt fackspråk för vård och omsorg samt förslag till förvaltning och utveckling.ResultatetResultatet innefattar bland annat att det internationella begreppssystemet Snomed CT är översatt till svenska och att det är förberett för förvaltning och distribution. Socialstyrelsen har även tagit fram och testat metoder för förvaltning och utveckling av det nationella fackspråket i sin helhet. Därtill har representanter för målgrupperna informerats och fått kunskap.Rapporten innehåller en utförlig beskrivning av det nationella fackspråkets sammantagna innehåll: Socialstyrelsens termbank, klassifikationer och kodverk, den svenska versionen av Snomed CT, metoder för utveckling och förvaltning samt regler för användning.Förvaltning, införande och resursbehovI rapporten finns förslag till hur hela det nationella fackspråket kan tas omhand av Socialstyrelsen och hur det kan införas i vården och omsorgen. Projektets övergång till en långsiktigt hållbar organisation kräver resurser. Därför redogör rapporten för det förväntade resursbehovet för förvaltning och utveckling. Bland annat föreslås en treårig utbildningsinsats samt stimulansbidrag för införande.Krav på styrning, samordning och förtydligat ansvarRapporten betonar behovet av en samlad och medveten styrning av utvecklingen inom området. Socialstyrelsen vill ha en samordnande roll i utvecklingen och förvaltningen av det nationella fackspråket. Myndigheten föreslås få det initiala ansvaret för att utbilda användare och att driva frågor om det nationella fackspråket.Vidare vill Socialstyrelsen få ett uttalat mandat att samordna de nationella aktiviteter som drivs med koppling till Snomed CT. Rapporten pekar ut några särskilt prioriterade områden som myndigheten borde få i uppdrag att arbeta vidare inom.Kunskapsstyrning och normgivningEn viktig slutsats i rapporten är att användningen av det nationella fackspråket behöver regleras för att målet om ökad säkerhet för klienter och patienter ska kunna uppnås. I dagsläget bedöms föreskrifter vara den metod som bäst kan garantera ett brett genomförande.Målgrupper för slutrapportenSlutrapporten riktar sig till beslutsfattare i kommuner och landsting, vård- och omsorgspersonal med särskilt intresse eller ansvar för dokumentationsfrågor och professionella organisationer.

Industrial Evaluation of Test Suite Generation Strategies for Model-Based Testing
- 2016
-
Konferensbidrag (refereegranskat)abstract
- We report on a case study on model based testing for a commercially available telecom software system. A main purpose is to investigate how different strategies for test suite generation affect quality attributes of the generated test suites, in a realistic industrial environment. We develop a functional model in the form of an extended finite state machine, from which we generate test suites using several different (model) coverage criteria, alongside with randomly and manually generated test suites. We compare test suites with respect to fault-detection capability, incurred (source) code coverage, and test generation and execution time. The system under test is a commercially released version, not seeded with any faults, implying that exposed faults are "real" faults that passed previous testing. We did not find clear difference between coverage-based and random test suites. Test suite generation and execution is performed using the tool ERLY MARSH, developed by the first author.

Model-Based Protocol Testing in an Erlang Environment
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Testing is the dominant technique for quality assurance of software systems. It typically consumes considerable resources in development projects, and is often performed in an ad hoc manner. This thesis is concerned with model-based testing, which is an approach to make testing more systematic and more automated. The general idea in model-based testing is to start from a formal model, which captures the intended behavior of the software system to be tested. On the basis of this model, test cases can be generated in a systematic way. Since the model is formal, the generation of test suites can be automated and with adequate tool support one can automatically quantify to which degree they exercise the tested software.Despite the significant improvements on model-based testing in the last 20 years, acceptance by industry has so far been limited. A number of commercially available tools exist, but still most testing in industry relies on manually constructed test cases.This thesis address this problem by presenting a methodology and associated tool support, which is intended to be used for model-based testing of communication protocol implementations in industry. A major goal was to make the developed tool suitable for industrial usage, implying that we had to consider several problems that typically are not addressed by the literature on model-based testing. The thesis presents several technical contributions to the area of model-based testing, including- a new specification language based on the functional programming language Erlang,- a novel technique for specifying coverage criteria for test suite generation, and- a technique for automatically generating test suites.Based on these developments, we have implemented a complete tool chain that generates and executes complete test suites, given a model in our specification language. The thesis also presents a substantial industrial case study, where our technical contributions and the implemented tool chain are evaluated. Findings from the case study include that test suites generated using (model) coverage criteria have at least as good fault-detection capability as equally large random test suites, and that model-based testing could discover faults in previously well-tested software where previous testing had employed a relaxed validation of requirements.
