1.	Bäckman, Karin, et al. (author) Vårdens alltför svåra val? : kartläggning av prioriteringsarbete och analys av riksdagens principer och riktlinjer för prioriteringar i hälso- och sjukvården 2007 Reports (other academic/artistic)abstract PrioriteringsCentrum har på uppdrag av Socialstyrelsen genomfört en kartläggning av på vilket sätt hälso- och sjukvårdens huvudmän och andra centrala aktörer arbetar med prioriteringar och har utvärderat hur detta arbete överensstämmer med intentionerna i riksdagens beslut om prioriteringar. Vi har även analyserat innehållet i och tillämpningen av riksdagens riktlinjer för prioriteringar i hälso- och sjukvården. Det har skett genom en etisk analys och mot bakgrund av ett stort antal intervjuer i landsting och kommuner samt med representanter för statliga myndigheter och yrkesorganisationer och med ledning av vad som framkommit i tidigare uppföljningar. Vi föreslår i rapporten ett anta förändringar och förtydliganden av riktlinjerna.Vi kan konstatera att sättet att arbeta med prioriteringar i landsting och kommuner inte är helt olikt det som gällde när Prioriteringsdelegationen redovisade en motsvarande uppföljning år 2001. Fortfarande finns knappast några öppna beslut om fördelning och prioritering av resurser om man med öppenhet avser att beslutsfattaren medvetet överväger flera alternativ och att grunderna för besluten är kända för dem som önskar ta del av dem.I situationer då tillgängliga resurser inte befinner sig i paritet med önskvärda ambitioner får sjukvårdspersonalen ta det största ansvaret för att besluta om och genomföra ransonering av vården. Förutom på chefsnivå tycks dock sjukvårdpersonal fortfarande i liten utsträckning vara medveten om de etiska principer som enligt riksdagsbeslutet ska styra prioriteringar i vården. Få känner till den etiska plattformen med de tre etiska principerna. Lokala mallar eller styrdokument för prioriteringar är ovanliga. Det saknas nödvändiga förutsättningar för att tillämpa riksdagens prioriteringsbeslut och det finns inte heller några tydliga strategier för hur man vill skapa sådana förutsättningar inom landstingen.Den kommunala vård- och omsorgsverksamheten upplever sig fortfarande i ringa utsträckning berörd av den etiska plattformen och prioriteringsprinciperna. Någon gemensam prioritering mellan huvudmännen sker knappast alls.Medborgarna är i mycket liten utsträckning involverade i prioriteringsarbetet. Den ökade öppenheten gentemot brukare innebär oftast att viss information om prioriteringar sker genom traditionella kanaler som patientorganisationer, pensionärsråd och handikappråd och synpunkter inhämtas via allmänna patientenkäter medan klagomål hanteras genom patientnämnder.Vi har också funnit tydliga skillnader när det gäller hur arbetet med prioriteringar bedrivs idag jämfört med för sex år sedan. Genom Socialstyrelsen och Läkemedelsförmånsnämnden har staten tagit ledningen när det gäller att visa hur prioriteringar kan göras på ett systematiskt och öppet sätt. Detta arbete har resulterat i en tydlig metodutveckling. Idag finns det dessutom flera exempel på konkret utvecklingsarbete och samverkan mellan huvudmän kring det vidare begreppet kunskapsstyrd vård till vilket systematiska prioriteringar är starkt relaterat. Vi kan också notera olika initiativ till vertikala prioriteringar i verksamheten där det framförallt är läkarkåren som engagerat sig; men också enstaka försök med systematiska politiska prioriteringar. Det finns dessutom flera lovande utvecklingsprojekt rörande prioriteringar som initierats av och drivs av sjukvårdspersonal både lokalt och nationellt. Yrkesförbunden är också mer aktiva idag när det gäller att sprida kunskap om prioriteringar....

3.	Ericsson, Per, et al. (author) Characterization of particulate emissions and methodology for oxidation of particulates from non-diesel combustion systems 2008 In: SAE Technical Paper. - 400 Commonwealth Drive, Warrendale, PA, United States : SAE International. - 0148-7191. Journal article (peer-reviewed)abstract Tailpipe particulate emissions, i.e., particle number, size distribution and total mass, from a series of four-cylinder engines with 2L displacement and power output of approximately 150 hp have been measured. The engines were in their respective vehicle installation, all midsize vehicles from various manufacturers, and represented different combustion concepts, i.e., port- and direct-injected vehicles and E5 and E85 fuels. The results are compared to post-Euro V emission standards for gasoline and biofuels using diesel as reference. The results show that the type of combustion and fuel significantly affect the particulate formation. In general, direct-injected engines show high particle numbers and mass compared to port-injected engines. The particulate number and total mass can be reduced by using biofuels, e.g., ethanol mixes, instead of gasoline. Moreover, an experimental procedure and setup facilitating precise studies of oxidation of particulates in realistic filter structures by well-controlled gas flow (composition and temperature) and sample (particulate load and temperature) conditions has been developed. The results from this method have been verified by using commercial soot as reference.
4.	Hägg, Daniel, 1974, et al. (author) Expression profiling of macrophages from subjects with atherosclerosis to identify novel susceptibility genes. 2008 In: International journal of molecular medicine. - 1107-3756. ; 21:6, s. 697-704 Journal article (peer-reviewed)abstract Although a number of environmental risk factors for atherosclerosis have been identified, heredity seems to be a significant independent risk factor. The aim of our study was to identify novel susceptibility genes for atherosclerosis. The screening process consisted of three steps. First, expression profiles of macrophages from subjects with atherosclerosis were compared to macrophages from control subjects. Secondly, the subjects were genotyped for promoter region polymorphisms in genes with altered gene expression. Thirdly, a population of subjects with coronary heart disease and control subjects were genotyped to test for an association with identified polymorphisms that affected gene expression. Twenty-seven genes were differentially expressed in both macrophages and foam cells from subjects with atherosclerosis. Three of these genes, IRS2, CD86 and SLC11A1 were selected for further analysis. Foam cells from subjects homozygous for the C allele at the -765C-->T SNP located in the promoter region of IRS2 had increased gene expression compared to foam cells from subjects with the nonCC genotype. Also, macrophages and foam cells from subjects homozygous for allele 2 at a repeat element in the promoter region of SLC11A1 had increased gene expression compared to macrophages and foam cells from subjects with the non22 genotype. Genotyping of 512 pairs of subjects with coronary heart disease (CHD) and matched controls revealed that subjects homozygous for C of the IRS2 SNP had an increased risk for CHD; odds ratio 1.43, p=0.010. Immunohistochemical staining of human carotid plaques showed that IRS2 expression was localised to macrophages and endothelial cells in vivo. Our method provides a reliable approach for identifying susceptibility genes for atherosclerosis, and we conclude that elevated IRS2 gene expression in macrophages may be associated with an increased risk of CHD.

6.	Lau, Joey, et al. (author) Implantation site-dependent dysfunction of transplanted pancreatic islets 2007 In: Diabetes. - : American Diabetes Association. - 0012-1797 .- 1939-327X. ; 56:6, s. 1544-1550 Journal article (peer-reviewed)abstract OBJECTIVE—Clinical islet transplantations are performed through infusion of islets via the portal vein into the liver. This study aimed at characterizing the influence of the implantation microenvironment on islet graft metabolism and function. RESEARCH DESIGN AND METHODS—Islets were transplanted into their normal environment, i.e., the pancreas, or intraportally into the liver of mice. One month posttransplantation, the transplanted islets were retrieved and investigated for changes in function and gene expression. RESULTS—Insulin content, glucose-stimulated insulin release, (pro)insulin biosynthesis, and glucose oxidation rate were markedly decreased in islets retrieved from the liver, both when compared with islets transplanted into the pancreas and endogenous islets. Islets transplanted into the pancreas showed normal insulin content, (pro)insulin biosynthesis, and glucose oxidation rate but increased basal insulin secretion and impaired glucose stimulation index. Gene expression data for retrieved islets showed downregulation of pancreatic and duodenal homeobox gene-1, GLUT-2, glucokinase, mitochondrial glycerol-phosphate dehydrogenase, and pyruvate carboxylase, preferentially in intraportally transplanted islets. CONCLUSIONS—Islets transplanted into their normal microenvironment, i.e., the pancreas, display gene expression changes when compared with endogenous islets but only moderate changes in metabolic functions. In contrast, site-specific properties of the liver markedly impaired the metabolic functions of intraportally transplanted islets.
7.	Margolin, Sara, et al. (author) A randomised feasibility/phase II study (SBG 2004-1) with dose-dense/tailored epirubicin, cyclophoshamide (EC) followed by docetaxel (T) or fixed dosed dose-dense EC/T versus T, doxorubicin and C (TAC) in node-positive breast cancer. 2011 In: Acta Oncologica. - : Informa Healthcare. - 0284-186X .- 1651-226X. ; 50:1, s. 35-41 Journal article (peer-reviewed)abstract The aim of the study was to evaluate the feasibility of tailored and dose-dense epirubicin and cyclophosphamide followed by docetaxel as adjuvant breast cancer therapy. Material and methods. Patients with node-positive breast cancer received either four cycles of biweekly and tailored EC (epirubicin 38-60-75-90-105-120 mg/m(2), cyclophosphamide 450-600-900-1200 mg/m(2)) followed by four cycles of docetaxel (60-75-85-100 mg/m(2)) (arm A) or the same regimen with fixed doses (E(90)C(600) + 4 → T(75) + 4) (arm B) or docetaxel, doxorubicin and cyclophosphamide (T(75)A(50)C(500)) every three weeks for six cycles (arm C). All patients received G-CSF support and prophylactic ciprofloxacin. Results. One-hundred and twenty-four patients were randomised in the study. In the A, B and C arm, 17% 19% and 3% of the patients had one or more cycles delayed due to side-effects whereas 24%, 5% and 15% experienced a grade 3 infection or febrile neutropenia. After the introduction of an extra week between the EC and T parts in the A and B arms, grade 3 hand-foot-skin reactions were reduced from 5 to 0.2%. Twenty-nine percent (A and B) and 20% (C) of the patients were hospitalised due to side-effects. Discussion. Dose-dense and tailored EC/T can be given with manageable toxicity and is after adjustment presently studied in the phase III Panther trial.
8.	Rönnbäck, Annica, et al. (author) Gene expression profiling of the rat hippocampus one month after focal cerebral ischemia followed by enriched environment 2005 In: Neuroscience Letters. - : Elsevier BV. - 0304-3940 .- 1872-7972. ; 385:2, s. 173-178 Journal article (peer-reviewed)abstract Functional recovery after experimental stroke in rats is enhanced by environmental enrichment by stimulating plastic changes in brain regions outside the lesion, but the molecular mechanisms are not known. We investigated the effect of environmental enrichment after focal cerebral ischemia on cognitive recovery and hippocampal gene expression using microarray analysis. Rats placed in enriched environment (EE) for 1 month after middle cerebral artery occlusion (MCAo) showed significantly improved spatial memory in the Morris water maze compared to rats housed alone after MCAo. Microarray analysis suggested several EE-induced differences in neuronal plasticity-related genes, but these changes could not be confirmed by quantitative real-time PCR. This study highlights some of the potential problems associated with gene expression profiling of brain tissues. Further studies at earlier time points and in additional subregions of the brain are of interest in the search for molecular mechanisms behind EE-induced neuronal plasticity after ischemic stroke.
9.	Svensson, Per Anders, 1959, et al. (author) Identification of genes predominantly expressed in human macrophages 2004 In: Atherosclerosis. - : Elsevier BV. ; 177, s. 287-290 Journal article (peer-reviewed)abstract Identification of cell and tissue specific genes may provide novel insights to signaling systems and functions. Macrophages play a key role in many diseases including atherosclerosis. Using DNA microarrays we compared the expression of approximately 10,000 genes in 56 human tissues and identified 23 genes with predominant expression in macrophages. The identified genes include both genes known to be macrophage specific and genes previously not well described in this cell type. Tissue distribution of two genes, liver X receptor (LXR) alpha and interleukin-1 receptor antagonist (IL1RN), was verified by real-time RT-PCR. We conclude that comparison of expression profiles from a large number of tissues can be used to identify genes that are predominantly expressed in certain tissues. Identification of novel macrophage specific genes may increase our understanding of the role of this cell in different diseases.
10.	Svensson, Per-Arne, 1969, et al. (author) Regulation and splicing of scavenger receptor class B type I in human macrophages and atherosclerotic plaques 2005 In: BMC Cardiovasc Disord. - : Springer Science and Business Media LLC. - 1471-2261. ; 5 Journal article (peer-reviewed)abstract BACKGROUND: The protective role of high-density lipoprotein (HDL) in the cardiovascular system is related to its role in the reverse transport of cholesterol from the arterial wall to the liver for subsequent excretion via the bile. Scavenger receptor class B type I (SR-BI) binds HDL and mediates selective uptake of cholesterol ester and cellular efflux of cholesterol to HDL. The role of SR-BI in atherosclerosis has been well established in murine models but it remains unclear whether SR-BI plays an equally important role in atherosclerosis in humans. The aim of this study was to investigate the expression of SR-BI and its isoforms in human macrophages and atherosclerotic plaques. METHODS: The effect of hypoxia and minimally modified low-density lipoprotein (mmLDL), two proatherogenic stimuli, on SR-BI expression was studied in human monocyte-derived macrophages from healthy subjects using real-time PCR. In addition, SR-BI expression was determined in macrophages obtained from subjects with atherosclerosis (n = 15) and healthy controls (n = 15). Expression of SR-BI isoforms was characterized in human atherosclerotic plaques and macrophages using RT-PCR and DNA sequencing. RESULTS: SR-BI expression was decreased in macrophages after hypoxia (p < 0.005). In contrast, SR-BI expression was increased by exposure to mmLDL (p < 0.05). There was no difference in SR-BI expression in macrophages from patients with atherosclerosis compared to controls. In both groups, SR-BI expression was increased by exposure to mmLDL (p < 0.05). Transcripts corresponding to SR-BI and SR-BII were detected in macrophages. In addition, a third isoform, referred to as SR-BIII, was discovered. All three isoforms were also expressed in human atherosclerotic plaque. Compared to the other isoforms, the novel SR-BIII isoform was predicted to have a unique intracellular C-terminal domain containing 53 amino acids. CONCLUSION: We conclude that SR-BI is regulated by proatherogenic stimuli in humans. However, we found no differences between subjects with atherosclerosis and healthy controls. This indicates that altered SR-BI expression is not a common cause of atherosclerosis. In addition, we identified SR-BIII as a novel isoform expressed in human macrophages and in human atherosclerotic plaques.
11.	Ahlin, Sofie, 1985, et al. (author) Macrophage Gene Expression in Adipose Tissue is Associated with Insulin Sensitivity and Serum Lipid Levels Independent of Obesity. 2013 In: Obesity (Silver Spring, Md.). - : Wiley. - 1930-739X .- 1930-7381. ; 21:12 Journal article (peer-reviewed)abstract Objective: Obesity is linked to both increased metabolic disturbances and increased adipose tissue macrophage infiltration. However, whether macrophage infiltration directly influences human metabolism is unclear. The aim of this study was to investigate if there are obesity-independent links between adipose tissue macrophages and metabolic disturbances. Design and Methods: Expression of macrophage markers in adipose tissue was analyzed by DNA microarrays in the SOS Sib Pair study and in patients with type 2 diabetes and a BMI-matched healthy control group. Results: The expression of macrophage markers in adipose tissue was increased in obesity and associated with several metabolic and anthropometric measurements. After adjustment for BMI, the expression remained associated with insulin sensitivity, serum levels of insulin, C-peptide, high density lipoprotein cholesterol (HDL-cholesterol) and triglycerides. In addition, the expression of most macrophage markers was significantly increased in patients with type 2 diabetes compared to the control group. Conclusion: Our study shows that infiltration of macrophages in human adipose tissue, estimated by the expression of macrophage markers, is increased in subjects with obesity and diabetes and associated with insulin sensitivity and serum lipid levels independent of BMI. This indicates that adipose tissue macrophages may contribute to the development of insulin resistance and dyslipidemia.
12.	Almstedt, Karin, 1980-, et al. (author) Unfolding a folding disease: folding, misfolding and aggregation of the marble brain syndrome-associated mutant H107Y of human carbonic anhydrase II 2004 In: Journal of Molecular Biology. - Oxford : Elsevier. - 0022-2836 .- 1089-8638. ; 342:2, s. 619-633 Journal article (peer-reviewed)abstract Most loss-of-function diseases are caused by aberrant folding of important proteins. These proteins often misfold due to mutations. The disease marble brain syndrome (MBS), known also as carbonic anhydrase II deficiency syndrome (CADS), can manifest in carriers of point mutations in the human carbonic anhydrase II (HCA II) gene. One mutation associated with MBS entails the His107Tyr substitution. Here, we demonstrate that this mutation is a remarkably destabilizing folding mutation. The loss-of-function is clearly a folding defect, since the mutant shows 64% of CO2 hydration activity compared to that of the wild-type at low temperature where the mutant is folded. On the contrary, its stability towards thermal and guanidine hydrochloride (GuHCl) denaturation is highly compromised. Using activity assays, CD, fluorescence, NMR, cross-linking, aggregation measurements and molecular modeling, we have mapped the properties of this remarkable mutant. Loss of enzymatic activity had a midpoint temperature of denaturation (Tm) of 16 °C for the mutant compared to 55 °C for the wild-type protein. GuHCl-denaturation (at 4 °C) showed that the native state of the mutant was destabilized by 9.2 kcal/mol. The mutant unfolds through at least two equilibrium intermediates; one novel intermediate that we have termed the molten globule light state and, after further denaturation, the classical molten globule state is populated. Under physiological conditions (neutral pH; 37 °C), the His107Tyr mutant will populate the molten globule light state, likely due to novel interactions between Tyr107 and the surroundings of the critical residue Ser29 that destabilize the native conformation. This intermediate binds the hydrophobic dye 8-anilino-1-naphthalene sulfonic acid (ANS) but not as strong as the molten globule state, and near-UV CD reveals the presence of significant tertiary structure. Notably, this intermediate is not as prone to aggregation as the classical molten globule. As a proof of concept for an intervention strategy with small molecules, we showed that binding of the CA inhibitor acetazolamide increases the stability of the native state of the mutant by 2.9 kcal/mol in accordance with its strong affinity. Acetazolamide shifts the Tm to 34 °C that protects from misfolding and will enable a substantial fraction of the enzyme pool to survive physiological conditions.

(author) The effect of the Siberian tundra on the environment of the shelf seas and the Arctic Ocean 1999 In: Ambio. - 0044-7447. ; 28:3, s. 270-280 Journal article (peer-reviewed)abstract The Tundra Ecology -94 expedition investigated inflow of inorganic and organic carbon to the shelf seas by river runoff, and its transformation by biochemical processes in seawater and sediment. In addition, anthropogenic radionuclides, 137Cs, 90Sr, and 239,240Pu, were studied in water and sediments. The distribution of dissolved inorganic carbon indicates that the majority of the Ob and Yenisey discharges flow into the Laptev Sea before entering the central Arctic Ocean. The sediment study shows that there is a marked difference in benthic oxygen uptake, efflux of dissolved inorganic carbon and nutrients between localities. 137Cs activity from the Chernobyl accident is 30% in the Barents, Kara, and Laptev Seas. 137Cs increased from 5-8 Bq m-3 in Barents Sea, 5-13 Bq m-3 in the Kara Sea to 8-15 Bq m-3 in the Laptev Sea, but with locally low concentrations at the river mouths. Corresponding values for 90Sr were 2.5, 3, and 4 Bq m-3, respectively.

15.	Andersson-Assarsson, Johanna C., 1974, et al. (author) Evolution of age-related mutation-driven clonal haematopoiesis over 20 years is associated with metabolic dysfunction in obesity 2023 In: Ebiomedicine. - 2352-3964. ; 92 Journal article (peer-reviewed)abstract Background Haematopoietic clones caused by somatic mutations with >= 2% variant allele frequency (VAF) increase with age and are linked to risk of haematological malignancies and cardiovascular disease. Recent observations suggest that smaller clones (VAF<2%) are also associated with adverse outcomes. Our aims were to determine the prevalence of clonal haematopoiesis driven by clones of variable sizes in individuals with obesity treated by usual care or bariatric surgery (a treatment that improves metabolic status), and to examine the expansion of clones in relation to age and metabolic dysregulation over up to 20 years.Methods Clonal haematopoiesis-driver mutations (CHDMs) were identified in blood samples from participants of the Swedish Obese Subjects intervention study. Using an ultrasensitive assay, we analysed single-timepoint samples from 1050 individuals treated by usual care and 841 individuals who had undergone bariatric surgery, and multiple-timepoint samples taken over 20 years from a subset (n = 40) of the individuals treated by usual care.Findings In this explorative study, prevalence of CHDMs was similar in the single-timepoint usual care and bariatric surgery groups (20.6% and 22.5%, respectively, P = 0.330), with VAF ranging from 0.01% to 31.15%. Clone sizes increased with age in individuals with obesity, but not in those who underwent bariatric surgery. In the multiple-timepoint analysis, VAF increased by on average 7% (range -4% to 24%) per year and rate of clone growth was negatively associated with HDL-cholesterol (R = -0.68, 1.74 E-04).Interpretation Low HDL-C was associated with growth of haematopoietic clones in individuals with obesity treated by usual care.
16.	Andersson, Tobias, 1976, et al. (author) Country of birth and mortality risk in hypertension with and without diabetes: the Swedish primary care cardiovascular database. 2021 In: Journal of hypertension. - 1473-5598. ; 39:6, s. 1155-1162 Journal article (peer-reviewed)abstract Hypertension and diabetes are common and are both associated with high cardiovascular morbidity and mortality. We aimed to investigate associations between mortality risk and country of birth among hypertensive individuals in primary care with and without concomitant diabetes, which has not been studied previously. In addition, we aimed to study the corresponding risks of myocardial infarction and ischemic stroke.This observational cohort study of 62557 individuals with hypertension diagnosed 2001-2008 in the Swedish Primary Care Cardiovascular Database assessed mortality by the Swedish Cause of Death Register, and myocardial infarction and ischemic stroke by the National Patient Register. Cox regression models were used to estimate study outcome hazard ratios by country of birth and time updated diabetes status, with adjustments for multiple confounders.During follow-up time without diabetes using Swedish-born as reference, adjusted mortality hazard ratios per country of birth category were Finland: 1.26 (95% confidence interval 1.15-1.38), high-income European countries: 0.84 (0.74-0.95), low-income European countries: 0.84 (0.71-1.00) and non-European countries: 0.65 (0.56-0.76). The corresponding adjusted mortality hazard ratios during follow-up time with diabetes were high-income European countries: 0.78 (0.63-0.98), low-income European countries: 0.74 (0.57-0.96) and non-European countries: 0.56 (0.44-0.71). During follow-up without diabetes, the corresponding adjusted hazard ratio of myocardial infarction was increased for Finland: 1.16 (1.01-1.34), whereas the results for ischemic stroke were inconclusive.In Sweden, hypertensive immigrants (with the exception for Finnish-born) with and without diabetes have a mortality advantage, as compared to Swedish-born.
17.	Andersson, Tobias, 1976, et al. (author) Mortality trends and cause of death in patients with new-onset type 2 diabetes and controls: A 24-year follow-up prospective cohort study. 2018 In: Diabetes research and clinical practice. - : Elsevier BV. - 1872-8227 .- 0168-8227. ; 138, s. 81-89 Journal article (peer-reviewed)abstract Our aim was to assess causes of death and temporal changes in excess mortality among patients with new-onset type 2 diabetes in Skaraborg, Sweden.Patients from the Skaraborg Diabetes Register with prospectively registered new-onset type 2 diabetes 1991-2004 were included. Five individual controls matched for sex, age, geographical area and calendar year of study entry were selected using population records. Causes of deaths until 31 December 2014 were retrieved from the Cause of Death Register. Adjusted excess mortality among patients and temporal changes of excess mortality were calculated using Poisson models. Cumulative incidences of cause-specific mortality were calculated by competing risk regression.During 24years of follow-up 4364 deaths occurred among 7461 patients in 90,529 person-years (48.2/1000 person-years, 95% CI 46.8-49.7), and 18,541 deaths in 479,428 person-years among 37,271 controls (38.7/1000 person-years, 38.1-39.2). The overall adjusted mortality hazard ratio was 1.47 (p<.0001) among patients diagnosed at study start 1991 and decreased by 2% (p<.0001) per increase in calendar year of diagnosis until 2004. Excess mortality was mainly attributed to endocrine and cardiovascular cause of death with crude subdistributional hazard ratios of 5.06 (p<.001) and 1.22 (p<.001).Excess mortality for patients with new-onset type 2 diabetes was mainly attributed to deaths related to diabetes and the cardiovascular system, and decreased with increasing year of diagnosis 1991-2004. Possible explanations could be temporal trends of earlier diagnosis due to lowered diagnostic thresholds and intensified diagnostic activities, as well as improved treatment.
18.	Andersson, Tobias, 1976, et al. (author) The impact of diabetes, education and income on mortality and cardiovascular events in hypertensive patients: A cohort study from the Swedish Primary Care Cardiovascular Database (SPCCD). 2020 In: PloS one. - : Public Library of Science (PLoS). - 1932-6203. ; 15:8 Journal article (peer-reviewed)abstract In this study we aimed to estimate the effect of diabetes, educational level and income on the risk of mortality and cardiovascular events in primary care patients with hypertension.We followed 62,557 individuals with hypertension diagnosed 2001-2008, in the Swedish Primary Care Cardiovascular Database. Study outcomes were death, myocardial infarction, and ischemic stroke, assessed using national registers until 2012. Cox regression models were used to estimate adjusted hazard ratios of outcomes according to diabetes status, educational level, and income.During follow-up, 13,231 individuals died, 9981 were diagnosed with diabetes, 4431 with myocardial infarction, and 4433 with ischemic stroke. Hazard ratios (95% confidence intervals) for diabetes versus no diabetes: mortality 1.57 (1.50-1.65), myocardial infarction 1.24 (1.14-1.34), and ischemic stroke 1.17 (1.07-1.27). Hazard ratios for diabetes and ≤9 years of school versus no diabetes and >12 years of school: mortality 1.56 (1.41-1.73), myocardial infarction 1.36 (1.17-1.59), and ischemic stroke 1.27 (1.08-1.50). Hazard ratios for diabetes and income in the lowest fifth group versus no diabetes and income in the highest fifth group: mortality 3.82 (3.36-4.34), myocardial infarction 2.00 (1.66-2.42), and ischemic stroke 1.91 (1.58-2.31).Diabetes combined with low income was associated with substantial excess risk of mortality, myocardial infarction and ischemic stroke among primary care patients with hypertension.
19.	Anderzen-Carlsson, Agneta, 1966-, et al. (author) Knowledge, skills and information needs on older residents’ hearing loss and hearing aids : Translation and adaptation of a Norwegian instrument 2022 Conference paper (peer-reviewed)abstract Objective: The objective with the project is to find a valid and culturally appropriate instrument for measuring the professionals' knowledge, skills and information needs on older residents’ hearing loss and hearing aids. Such an instrument could optimally be used in clinical praxis, as well as in research, for cross-sectional studies and for measuring change related to educational interventions.Materials: The Norwegian instrument Knowledge, skills and information needs on residents’ hearing loss and hearing aids was identified in the literature. Its content was, by the research group regarded as relevant in a Swedish setting, although some cultural adaptations seemed to be necessary.Methods: The translation and cultural adaptations were performed in line with the International Society For Pharmacoeconomics and Outcomes Research (ISPOR) Task Force For Translation and Cultural Adapation, as outlined below:1. We first asked one of the original authors for permission to translate the instrument.2. Two of the authors (KB and MB) individually translated the content of the instrument. Their first language is Swedish, but both are familiar with the Norwegian language.3. The other authors individually and together checked the translations and judged whether the statements were comprehensible in Swedish, and made necessary cultural adaptations. For example, the nursing home settings, and job types within this sector are not identical in the two countries.4. An independent person, with knowledge of both Swedish and Norwegian (Norwegian being the first language), but with no previous knowledge of the instrument made a back-translation. This person had good knowledge of the setting, being a professor in geriatrics.5. The authors compared the original version of the instrument with the back-translated version and discussed some inconsistences with the first author of the original instrument, before we all agreed on a first preliminary Swedish version.6. 12 professionals having audiological competence, experience of nursing older people or teaching in nursing piloted the first preliminary Swedish version. They suggested some reformulations of questions and responses, which were discussed and decided on within the research group.7. The next step is to test the preliminary Swedish version of the instrument, which will take place during the winter of 2019-2020. A sample of professionals working in different nursing homes in two Swedish counties will be invited to participate. The plan is to include 400 professionals. The sample size is based on an optimal sample for performing a factor analysis as part of the assessment of the psychometric properties of the preliminary Swedish version. It also allows cross-sectional sub-analyses, based on different groups of professionals and level of nursing home.8. The project will be presented in a scientific journal, and used in a future intervention study. The instrument can also be used in clinical improvement work.Conclusion: The results are promising. To the best of our knowledge, there is no Swedish instrument available for measuring professionals' knowledge, skills and information needs on older residents’ hearing loss and hearing aids. It seems necessary to have such an instrument, as the number of older people increases in Sweden, as well as worldwide. Impaired hearing, as well as assistive needs increase with age, and thus it is of great importance to ensure that professionals working with older people have sufficient knowledge to assist them.

(author) Violaxanthin accessibility and temperature dependency for de-epoxidation in spinach thylakoid membranes 1997 In: Photosynthesis Research. - 0166-8595. ; 52:1, s. 39-48 Journal article (peer-reviewed)abstract Using DTT and iodoacetamide as a novel irreversible method to inhibit endogenous violaxanthin de-epoxidase, we found that violaxanthin could be converted into zeaxanthin from both sides of the thylakoid membrane provided that purified violaxanthin de-epoxidase was added. The maximum conversion was the same from both sides of the membrane. Temperature was found to have a strong influence both on the rate and degree of maximal violaxanthin to zeaxanthin conversion. Thus only 50% conversion of violaxanthin was detected at 4 degreesC, whereas at 25 degreesC and 37 degreesC the degree of conversion was 70% and 80%, respectively. These results were obtained with isolated thylakoids from non-cold acclimated leafs. Pigment analysis of sub-thylakoid membrane domains showed that violaxanthin was evenly distributed between stroma lamellae and grana partitions. This was in contrast to chlorophyll a and beta-carotene which were enriched in stroma lamellae fractions while chlorophyll b, lutein and neoxanthin were enriched in the grana membranes. In combination with added violaxanthin de-epoxidase we found almost the same degree of conversion of violaxanthin to zeaxanthin (73-78%) for different domains of the thylakoid membrane. We conclude that violaxanthin de-epoxidase converts violaxanthin in the lipid matrix and not at the proteins, that violaxanthin does not prefer one particular membrane region or one particular chlorophyll protein complex, and that the xanthophyll cycle pigments are oriented in a vertical manner in order to be accessible from both sides of the membrane when located in the lipid matrix.

Despite progress in the generation of stem-cell-derived islets (SC-islets), no detailed characterization of their functional properties has been conducted. Here, we generated functionally mature SC-islets using an optimized protocol and benchmarked them comprehensively against primary adult islets. Biphasic glucose-stimulated insulin secretion developed during in vitro maturation, associated with cytoarchitectural reorganization and the increasing presence of alpha cells. Electrophysiology, signaling and exocytosis of SC-islets were similar to those of adult islets. Glucose-responsive insulin secretion was achieved despite differences in glycolytic and mitochondrial glucose metabolism. Single-cell transcriptomics of SC-islets in vitro and throughout 6 months of engraftment in mice revealed a continuous maturation trajectory culminating in a transcriptional landscape closely resembling that of primary islets. Our thorough evaluation of SC-islet maturation highlights their advanced degree of functionality and supports their use in further efforts to understand and combat diabetes.

(author) Could benefits of epidural analgesia following oesophagectomy be measured by perceived perioperative patient workload? 2008 In: Acta Anaesthesiologica Scandinavica. - : Wiley. - 0001-5172 .- 1399-6576. ; 52:10, s. 1313-1318 Journal article (peer-reviewed)abstract Background: A controversy exists whether beneficial analgesic effects of epidural analgesia over intravenous analgesia influence the rate of post-operative complications and the length of hospital stay. There is some evidence that favours epidural analgesia following major surgery in high-risk patients. However, there is a controversy as to whether epidural analgesia reduces the intensive care resources following major surgery. In this study, we aimed at comparing the post-operative costs of intensive care in patients receiving epidural or intravenous analgesia.Methods: Clinical data and rates of post-operative complications were extracted from a previously reported trial following thoraco-abdominal oesophagectomy. Cost data for individual patients included in that trial were retrospectively obtained from administrative records. Two separate phases were defined: costs of pain treatment and the direct cost of intensive care.Results: Higher calculated costs of epidural vs. intravenous pain treatment, 1,037 vs. 410 Euros/patient, were outweighed by lower post-operative costs of intensive care 5,571 vs. 7,921 Euros/patient (NS).Conclusion: Higher costs and better analgesic effects of epidural analgesia compared with intravenous analgesia do not reduce total costs for post-operative care following major surgery.

Material and Methods-Nasal biopsies were obtained from 23 patients with allergic rhinitis and 12 healthy controls. RNA was extracted from the biopsies and pooled into three patient and three control pools. These were then analysed in duplicate with DNA microarrays containing 12626 genes. Candidate genes were further examined in nasal biopsies (real-time polymerase chain reaction) and blood samples (single nucleotide polymorphisms) from other patients with allergic rhinitis and from controls. Results-A total of 37 differentially expressed genes were identified according to criteria involving both the size and consistency of the gene expression levels. The chromosomal location of these genes was compared with the chromosomal susceptibility regions for allergic disease. Using a statistical method, five genes were identified in these regions, including serine protease inhibitor, Kazal type, 5 (SPINK5) and HLA-DRB2. The relevance of these genes was examined in other patients with allergic rhinitis and in controls; none of the genes were differentially expressed in nasal biopsies. Moreover, no association between allergic rhinitis and SPINK5 polymorphisms was found, at either the genotype or haplotype level. Conclusions-DNA microarray analysis of chromosomal susceptibility regions did not lead to identification of candidate genes that could be validated in a new material. However, because gene polymorphisms may cause differential gene expression, further studies, including validation data, are needed to examine this approach.

25.	Benson, Mikael, 1954, et al. (author) DNA microarray analysis of transforming growth factor-β and related transcripts in nasal biopsies from patients with allergic rhinitis 2002 In: Cytokine. ; 18:1, s. 20-25 Journal article (peer-reviewed)abstract Decreased activity of anti-inflammatory cytokines like transforming growth factor (TGF)-β may contribute to allergic inflammation. In vivo effects of TGF-β-effects are difficult to infer from local concentrations, since TGF-β-effects depend on a complex system of regulatory proteins and receptors. Instead the effects of TGF-β might be inferred by examining TGF-β-inducible transcripts. In this study DNA microarrays were used to examine local expression of TGF-β, TGF-β-regulatory and -inducible transcripts in nasal biopsies from patients with symptomatic allergic rhinitis and healthy controls. In addition, nasal fluids were analysed with cytological and immunological methods. Nasal fluid eosinophils, albumin, eosinophil granulae proteins and IgE, but not TGF-β, were higher in patients than in controls. DNA microarray analysis of nasal mucosa showed expression of transcripts encoding TGF-β, TGF-β-regulatory proteins and -receptors at variable levels in patients and controls. By comparison, analysis of 28 TGF-β-inducible transcripts indicated that 23 of these had lower measurement values in patients than in controls, while one was higher, and the remaining four were absent in both patients and controls. In summary, TGF-β and a complex system of regulatory genes and receptors are expressed in the nasal mucosa. Low expression of TGF-β-inducible transcripts may indicate decreased TGF-β activity in allergic rhinitis. DNA microarray analysis may be a way to study cytokine effects in vivo.

We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.5–22.7) and 16.5 cm (13.3– 19.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8– 144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.
28.	Blom Johansson, Monica, 1965- (author) Aphasia and Communication in Everyday Life : Experiences of persons with aphasia, significant others, and speech-language pathologists 2012 Doctoral thesis (other academic/artistic)abstract The aims of this thesis were to describe the experiences of persons with aphasia and their significant others of their conversations and use of communication strategies, examine current practice of family-oriented speech-language pathology (SLP) services, and test a family-oriented intervention in the early phase of rehabilitation.The persons with aphasia valued having conversations despite perceiving their aphasia as a serious social disability. They acknowledged the importance of the communication partners’ knowledge and understanding of aphasia and their use of supporting conversation strategies. Their own use of communication strategies varied considerably. The persons with aphasia longed to regain language ability and to be active participants in society.A majority of the significant others perceived their conversations with the person with aphasia as being less stimulating and enjoyable than conversations before stroke onset. Aphasia was considered a serious problem. The significant others took on increased communicative responsibility, where two thirds had changed their communicative behaviour to facilitate conversations. Type and severity of aphasia were especially related to the communicative experiences of the significant others and their motivation to be involved in SLP services.Thirty percent of the speech-language pathologists worked with people with aphasia and typically met with their families. They considered the involvement of significant others in SLP services as very important, especially in providing information about aphasia and communication partner training (CPT). However, involvement of significant others was restricted because of a time shortage and perceived limited skills and knowledge. In addition, there were national differences regarding aphasia rehabilitation services.The intervention consisted of three sessions directed to significant others (primarily emotional support and information) and three directed to the dyads (a person with aphasia and a significant other) (primarily CPT). All six participants (three dyads) felt that their knowledge and understanding of aphasia had increased and that their conversations had improved. These improvements were also evident to some extent with formal assessments.These results suggest the following: CPT should be an integral part of SLP services, national clinical guidelines are needed, and further education of speech-language pathologists and implementation of new knowledge into clinical practice requires consideration.
29.	Boguszewski, C L, et al. (author) Cloning of two novel growth hormone transcripts expressed in human placenta. 1998 In: The Journal of clinical endocrinology and metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 83:8, s. 2878-85 Journal article (peer-reviewed)abstract Several isoforms of human GH (hGH) are produced by two related genes expressed in the pituitary (hGH-N) and in the placenta (hGH-V). These genes consist of five exons (denoted 1-5) separated by four introns (denoted A-D). In the present report, two new transcripts of the hGH-V gene are described. The coding region of the hGH-V gene was amplified by RT-PCR using placental complementary DNA as template. DNA sequencing of several clones revealed two novel transcripts. One had a 45-bp deletion caused by the use of an alternative splice acceptor site within exon 3, similar to that in the hGH-N gene, predicting a 20-kDa isoform of hGH-V. The other transcript was generated by the use of an alternative splice donor site causing a 4-bp deletion in the end of exon 4, predicting a 24-kDa protein with 219 amino acids, which we refer to as hGH-V3. The carboxy-terminal sequence of hGH-V3 differs from 22-kDa hGH-V and hGH-V2, the two previously reported transcripts of the hGH-V gene, and does not contain a predicted transmembrane domain as described for hGH-V2. Ligase chain reaction was then used to analyze the possible use of the same splicing pattern in transcripts derived from the other genes of the hGH-gene cluster. Alternatively spliced transcripts encoding the 20-kDa hGH isoform were detected from the hGH-N and hGH-V genes, but not from the human chorionic somatomammotropin-A/B genes. The alternative splicing generating hGH-V3 was only demonstrated in transcripts derived from the hGH-V gene. Using competitive RT-PCR, the expression of hGH-V3 was estimated to be 10% of the hGH-V messenger RNA in full-term normal placentas and in placentas from pathological pregnancies. The 20-kDa hGH-V was detected in two of four full-term normal placentas, whereas a weak signal was observed in one of the pathological placentas. We conclude that the hGH-V primary transcript undergoes alternative splicing pathways generating at least four different messenger RNAs, predicting the expression of different hGH isoforms, including two with a complete sequence divergence in the carboxy-terminus.

The surgery group underwent gastric bypass (n=265), banding (n=376), or vertical banded gastroplasty (n=1369). The control group (n=2037) received usual obesity care. Causes of death were obtained from the Swedish Cause of Death Register, case sheets and autopsy reports, in patients with baseline T2D (n=392 surgery patients/n=305 controls) or non-T2D (n=1609 surgery patients/n=1726 controls) during a median follow-up 26 years.In T2D and non-T2D subgroups, bariatric surgery was associated with increased life expectancy (2.1, 95% confidence interval (95% CI) 0.2-4.0; and 1.6, 0.5-2.7 years, respectively) and reduced overall mortality (adjusted hazard ratio (adjHR)=0.77, 95% CI: 0.61-0.97; and 0.82, 0.72-0.94, respectively), and the treatment benefit was similar (interaction p=0.615). Bariatric surgery was associated with reduced cardiovascular mortality in both subgroups (adjHR=0.65, 95% CI: 0.46-0.91; and 0.70, 0.55-0.88, respectively (interaction p=0.516)).Bariatric surgery is associated with similar reduction of overall and cardiovascular mortality and increased life expectancy regardless of baseline diabetes status.

Diabetes & endocrinology. - 2213-8595. ; 5:4, s. 271-279 Journal article (peer-reviewed)abstract Bariatric surgery is associated with remission of diabetes and prevention of diabetic complications in patients with obesity and type 2 diabetes. Long-term effects of bariatric surgery on microvascular complications in patients with prediabetes are unknown. The aim of this study was to examine the effects of bariatric surgery on incidence of microvascular complications in patients with obesity stratified by baseline glycaemic status.Patients were recruited to the Swedish Obese Subjects (SOS) study between Sept 1, 1987, and Jan 31, 2001. Inclusion criteria were age 37-60 years and BMI of 34 kg/m(2) or greater in men and 38 kg/m(2) or greater in women. Exclusion criteria were identical in surgery and control groups and designed to exclude patients not suitable for surgery. The surgery group (n=2010) underwent gastric bypass (265 [13%]), gastric banding (376 [19%]), or vertical-banded gastroplasty (1369 [68%]). Participants in the control group (n=2037) received usual care. Bodyweight was measured and questionnaires were completed at baseline and at 0·5 years, 1 year, 2 years, 3 years, 4 years, 6 years, 8 years, 10 years, 15 years, and 20 years. Biochemical variables were measured at baseline and at 2 years, 10 years, and 15 years. We categorised participants into subgroups on the basis of baseline glycaemic status (normal [fasting blood glucose concentration <5·0 mmol/L], prediabetes [5·0-6·0 mmol/L], screen-detected diabetes [≥6·1 mmol/L at baseline visit without previous diagnosis], and established diabetes [diagnosis of diabetes before study inclusion]). We obtained data about first incidence of microvascular disease from nationwide registers and about diabetes incidence at study visits at 2 years, 10 years, and 15 years. We did the main analysis by intention to treat, and subgroup analyses after stratification by baseline glycaemic status and by diabetes status at the 15 year follow-up. The SOS study is registered with ClinicalTrials.gov, NCT01479452.4032 of the 4047 participants in the SOS study were included in this analysis. We excluded four patients with suspected type 1 diabetes, and 11 patients with unknown glycaemic status at baseline. At baseline, 2838 patients had normal blood glucose, 591 had prediabetes, 246 had screen-detected diabetes, and 357 had established diabetes. Median follow-up was 19 years (IQR 16-21). We identified 374 incident cases of microvascular disease in the control group and 224 in the surgery group (hazard ratio [HR] 0·56, 95% CI 0·48-0·66; p<0·0001). Interaction between baseline glycaemic status and effect of treatment on incidence of microvascular disease was significant (p=0·0003). Unadjusted HRs were lowest in the subgroup with prediabetes (0·18, 95% CI 0·11-0·30), followed by subgroups with screen-detected diabetes (0·39, 0·24-0·65), established diabetes (0·54, 0·40-0·72), and normoglycaemia (0·63, 0·48-0·81). Surgery was associated with reduced incidence of microvascular events in people with prediabetes regardless of whether they developed diabetes during follow-up.Bariatric surgery was associated with reduced risk of microvascular complications in all subgroups, but the greatest relative risk reduction was observed in patients with prediabetes at baseline. Our results suggest that prediabetes should be treated aggressively to prevent future microvascular events, and effective non-surgical treatments need to be developed for this purpose.US National Institutes of Health, Swedish Research Council, Sahlgrenska University Hospital Regional Agreement on Medical Education and Research, and Swedish Diabetes Foundation.

The aim of this study was therefore to study the association between bariatric surgery and long-term incidence of fall-related injuries in the prospective, controlled Swedish Obese Subjects study. At inclusion, body mass index was≥34kg/m2 in men and ≥38kg/m2 in women. The surgery per-protocol group (n=2007) underwent gastric bypass (n=266), banding (n=376), or vertical banded gastroplasty (n=1365), and controls (n=2040) received usual care. At the time of analysis (31 December 2013), median follow-up was 19 years (maximal 26 years). Fall-related injuries requiring hospital treatment were captured using data from the Swedish National Patient Register. During follow-up, there were 617 first-time fall-related injuries in the surgery group and 513 in the control group (adjusted hazard ratio 1.21, 95% CI, 1.07-1.36; P=0.002). The incidence differed between treatment groups (P<0.001, log-rank test) and was higher after gastric bypass than after usual care, banding and vertical banded gastroplasty (adjusted hazard ratio 0.50-0.52, P<0.001 for all three comparisons). In conclusion, gastric bypass surgery was associated with increased risk of serious fall-related injury requiring hospital treatment.

Simultaneously a high-speed camera was used to capture the behavior of the biomass particle as it was heated for about 0.1 s. Cover glasses were used as a sample holder which allowed for light microscope studies after the heating. Since the cover glasses are not initially heated by the laser, vapors from the biomass particle are quenched on the glass within about 1 particle diameter from the initial particle. Image processing was used to track the contour of the biomass particle and the enclosed area of the contour was calculated for each frame.The main observations are: There is a significant difference between how much surface energy is needed to pyrolyses the spruce (about 75% more) compared to the hardwood. The oil-like substance which appeared on the glass during the experiment is solid at room temperature and shows different levels of transparency. A fraction of this substance is water soluble. A brownish coat is seen on the unreacted biomass. The biomass showed insignificant swelling as it was heated. The biomass particle appears to melt and boil at the front that is formed between the laser beam and the biomass particle. The part of the particle that is not subjected to the laser beam seems to be unaffected.

The results strongly support a Swedish policy to offer all children with diagnosed hearing impairment genetic tests for the C×26 35delG mutation.Objectives: The aim of the present study was to search for mutations in the GBJ2 gene among Swedish persons with non-syndromic hearing impairment to further clarify how common these mutations are in Sweden, one of the northernmost countries in Europe.Methods: Seventy-nine patients with non-syndromic hearing impairment participated in the study. For 87% of the participants, a pure tone audiogram showed a severe or profound hearing impairment. Dried blood spots on filter paper, taken at 3-5 days of age in the Swedish nationwide neonatal screening programme for congenital disorders and saved in a biobank, were used for the molecular genetic analyses.Results: The total number of subjects with one or two pathologic mutations or a mutation of unknown consequence found in the GJB2 gene was 28 of 79 (35%). Nineteen (19) persons (24%) were homozygotes for the 35delG mutation.

41.	Carlsson, Per, 1951-, et al. (author) National Model for Transparent Vertical Prioritisation in Swedish Health Care 2007 Reports (other academic/artistic)abstract The proposed national model described in this report has been developed by a working group comprised of staff from the National Board of Health and Welfare, the National Centre for Priority Setting in Health Care, and other organisations involved in vertical prioritisation – including the Östergötland County Council, Stockholm County Council, Västra Götaland, the Health Services Region of Southern Sweden, the Swedish Society of Medicine, the Swedish Society of Nursing, and the Swedish Association of Health Professionals. Throughout the process of designing the model, the Swedish Federation of Occupational Therapists and the Swedish Association of Registered Physiotherapists were regularly informed and given opportunities to review and comment on the proposal. Furthermore, the report was reviewed and discussed at a meeting with invited representatives from the other county councils, the Pharmaceutical Benefits Board, and several professional interest groups. Viewpoints were also obtained at a seminar arranged by PrioNet, a network of individuals interested in prioritisation.Potentially, the working model described in Chapter 4 could be used in any context where vertical prioritisation takes place, e.g. activities arranged by the state, county councils, municipalities, hospital departments, and professional groups.This report is designed to be a useful tool for those working on development projects in priority setting. We believe that the contents must be adapted, with the help of relevant examples and some simplifications; to fit the specific needs of different projects or groups. The text must also be adapted to a target group’s knowledge and previous experience in dealing with transparent priority setting. It must be the responsibility of each provider and other affected organisation to adapt the material to the given situation and project. The National Centre for Priority Setting in Health Care, the National Board of Health and Welfare, and others who have participated actively in this effort can be helpful to various target groups in adapting this report.When and how to engage in practically implementing vertical prioritisation are questions that need to be answered at the local level. Primarily, it is the duty of the local authorities/providers to take responsibility for implementation. Professional organisations also play an important role. Public agencies, universities, and knowledge centres should be sources of support for the local authorities/providers.The Riksdag’s resolution on prioritisation served as the foundation for developing the model.Where there are areas of uncertainty in how to translate these guidelines in practice, or where practical implementation might conflict with the principles, we have pointed this out.Our conclusions and proposals are the following:When facing a choice – regardless of whether it involves allocating new resources for different purposes, or to implement cutbacks – it can be advantageous to rank the possible choices in order of priority. In our model, only the relevant options can be ranked by priority. The consequences of this ranking are not obvious at the outset, but can serve as a basis either to allocate more resources or ration by some means.In vertical prioritisation, it is advantageous to organise the prioritization process starting from a general categorisation of health problems/disease groups. As a rule, these categories cover many organisational units/clinical departments, specialties, or professional groups, thus providing a more multidimensional view of the problem. Furthermore, this allows the process to start from a patient/population perspective, which appears to be more goal-oriented than an organisational/staff perspective.That which is ranked, i.e. one of the choices, we refer to as a prioritization object. We suggest that prioritisation objects consist of different combinations of health conditions and interventions.1 When deciding on the appropriate level of detail, the decision must be based on the context in which prioritisation is carried out. A starting point would be to focus on typical cases, large-volumes services, and controversial care.All forms of vertical prioritisation should be based on the ethical principles that the Riksdag decided should apply in prioritising health services. However, these ethical principles must be made known, clarified, and perhaps complemented before they can be applied to practical priority setting. Furthermore, we believe that the Riksdag’s four so-called priority groups should not be part of the model.The human dignity principle, i.e. that all people should have equal value and equal rights to care irrespective of their personal characteristics and function in society, is the undisputed cornerstone in priority setting. When personal characteristics such as age, gender, lifestyle, or function of a group are expressions of the presence of special needs, so that benefits of the interventions are different, these personal characteristics could be addressed in a priority at the group level. Further discussion is needed regarding the question of how external effects (i.e. the effects of an intervention on families and groups other than the individual directly affected by the intervention) should be valued in priority setting.The concept of need in health care includes both the severity level of the condition and the expected benefits of intervention. As a patient, one needs only those interventions that can be expected to yield benefits. Based on this definition of need, a person does not need an intervention that does not improve health and quality of life, i.e. an intervention with no benefit. In such cases, health services have a responsibility to refer people who seek care for some type of problem, to other appropriate services.The Riksdag’s guidelines regarding the cost-effectiveness principle (applied to individual patients) are too limited to provide guidance for vertical prioritisation at the group level. From the outset, the Government’s bill (Priority Setting in Health Care) highlighted the importance of differentiating a cost-effectiveness principle that applied to choices among various interventions for the individual patient (where the principle can be applied as the Commission of Inquiry proposed) and the aim of health services to achieve high cost-effectiveness in health care generally. Here we also refer to the Riksdag’s directive to the Pharmaceutical Benefits Board. In its decisions on subsidising (prioritising) a drug, the Board should determine, e.g. whether the drug is cost effective from a societal perspective, which requires comparing the patient benefits of the drug to its cost. In such decisions, the cost effectiveness should be considered along with the needs and solidarity principle and the human dignity principle.The proposed working model essentially concurs with the working model used by the National Board of Health and Welfare in developing national guidelines. In describing a national working model, it is not possible to include every aspect that might be considered. Hence, one must start from the model and decide which other relevant aspects should be included. For instance, the International Classification on Functioning, Disability, and Health (ICF) can be used as guidance to describe the severity of health conditions.Due to the wealth of variety in outcome measures for different activities, and the limited experience in working with explicit threshold values, we believe would be premature to recommend standardised categories, e.g. risk levels. However, it is important that those working with prioritization describe their reasoning. Primarily, the categories applied by the Swedish Council on Technology Assessment in Health Care (SBU) to grade the scientific evidence of an intervention’s effects should be used. Local prioritisation projects with limited resources at their disposal should describe (text) their appraisal of the scientific evidence and reference the scientific sources used. The strength of evidence should be expressed in numbers only when supporting a conclusion of a systematic review by SBU, or other literature reviews of good quality.Prioritisation projects having access to health economic evaluation should, until further notice, adhere to the approach used by the National Board of Health and Welfare and present cost-effectiveness on a scale from low to very high cost per life-year gained or cost per quality-adjusted life-year. Economic evidence should be presented according to the principles applied by the National Board of Health and Welfare. In local projects with limited resources, or problems in consistently acquiring information on cost effectiveness, we recommend that the authors at least discuss cost effectiveness in cases where the priority ranking would be decisively affected when costs are weighed in.A 10-level ranking list should be used. The ranking list should be complemented by a “don’t do” list for methods that should not be used at all, or not used routinely, and a research and development (R&D) list for methods where the evidence still insufficient to motivate their use in standard practice. In the absence of an objective quantitative/mathematical method, a qualitative method should be used in the appraisal. Here too, we believe that it is not yet possible to establish standard criteria to determine within which ranking level a prioritisation object should fall.Results should be presented as a ranking list. The parameters used as a basis for prioritisation should also be presented in a uniform manner in ranking lists that are shared with other parties. For pedagogic reasons, details concerning language and format need to be adapted to the respective target groups.Thresholds for what constitutes an acceptable coverage of need (care quality, volume, and percentage of the patient group with access to services) a
42.	Carlsson, Per, 1951-, et al. (author) Nationell modell för öppna vertikala prioriteringar inom svensk hälso- och sjukvård 2007 Reports (other academic/artistic)abstract En arbetsgrupp med personer från Socialstyrelsen och PrioriteringsCentrum, andra organisationer som arbetat med vertikala prioriteringar såsom Landstinget i Östergötland, Stockholms läns landsting, Västra Götaland, Södra sjukvårdsregionen, Svenska Läkaresällskapet, Svensk sjuksköterskeförening och Vårdförbundet har tagit fram detta förslag. Förslaget har fortlöpande förankrats hos Förbundet Sveriges Arbetsterapeuter och Legitimerade Sjukgymnasters Riksförbund som kunnat lämna synpunkter på utformningen av odellen.Dessutom har rapporten varit föremål för granskning och diskussion vid ett möte med inbjudna representanter från övriga landsting, Läkemedelsförmånsnämnden och flera yrkesorganisationer. Synpunkter har också inkommit från ett seminarium som arrangerades av PrioNet, ett nätverk av personer med intresse för prioriteringar.Den arbetsmodell som beskrivs i kapitel 4 ska kunna användas i alla sammanhang där vertikala prioriteringar sker såsom aktiviteter som arrangeras av staten, landsting, kommuner, kliniker, professionella grupper eller motsvarande.Rapporten är skriven på ett sådant sätt att den ska kunna användas i första hand som ett stöd till dem som bedriver utvecklingsarbete rörande prioriteringar. Vi tror att innehållet måste anpassas till olika verksamheter eller personalgruppers specifika behov med hjälp av kompletterande exempel och vissa förenklingar. Texten måste givetvis också anpassas till de kunskaper och tidigare erfarenheter som den aktuella målgruppen har när det gäller arbete med öppna prioriteringar. Sådana situations- och verksamhetsanpassade versioner måste det åligga varje sjukvårdshuvudman och andra berörda organisationer att utarbeta. PrioriteringsCentrum, Socialstyrelsen och andra parter som deltagit aktivt i detta arbete kan givetvis vara behjälpliga i arbetet med att bearbeta denna rapport för olika målgrupper.Frågan om när och hur arbetet med vertikala prioriteringar ska bedrivas i praktiken kan också endast besvaras lokalt. Det är i första hand ett nsvar för huvudmännen att ta ansvar för implementeringen. Professionella organisationer har också en viktig roll. Myndigheter, universitet och kunskapscentra ska vara ett stöd till huvudmännen.Utgångspunkten i modellutvecklingen är Riksdagens beslut om prioriteringar. När det finns oklarheter om hur dessa riktlinjer ska omsättas i praktiken eller att praktiken kan förefalla i konflikt med principerna har vi påpekat detta.När man står inför ett val - oavsett om det handlar om att fördela nya resurser till olika ändamål eller att genomföra besparingar - kan det vara en fördel att kunna rangordna tänkbara valmöjligheter i enprioriteringsordning. I vår modell innebär prioritering enbart att de relevanta alternativen rangordnas. Konsekvenserna av denna rangordning är inte på förhand given utan kan ligga till grund såväl för tillskott av resurser som för ransonering av något slag.Vid en vertikal prioritering är det en fördel att organisera prioriteringsarbetet så att det utgår från en grov uppdelning i hälsoproblem/sjukdomsgrupper. En sådan uppdelning innebär i regel att flera organisationsenheter/kliniker, specialiteter eller yrkesgrupper berörs och man får en mer allsidig belysning av problemet. Dessutom utgår man från ett patient/befolkningsperspektiv vilket förefaller mer ändamålsenligt än ett organisatoriskt/personalperspektiv.Det som rangordnas och som någon väljer mellan benämner vi prioriteringsobjekt. Vi föreslår att prioriteringsobjektet utgörs av olika kombinationer av hälsotillstånd och åtgärder1. När det gäller att bestämma en lämplig detaljeringsgrad måste det avgöras utifrån sammanhanget prioriteringar ska göras i. En utgångspunkt är att fokusera på typfall, vård som representerar stor volym och kontroversiell vård.Alla former av vertikala prioriteringar ska baseras på de etiska principer som riksdagen beslutat ska gälla vid prioriteringar inom hälso- och sjukvården. De etiska principerna behöver dock göras kända, förtydligas och eventuellt kompletteras för att kunna omsättas i praktiska prioriteringar. Vidare anser vi att riksdagens fyra så kallade prioriteringsgrupper inte ska ingå i modellen.Människovärdesprincipen, som innebär att alla människor bör ha lika värde och samma rätt till vård oberoende av personliga egenskaper och funktioner i samhället, är den självklara utgångspunkten vid prioriteringar. När personliga egenskaper såsom ålder, kön, livsstil eller funktion hos en grupp är ett uttryck för att speciella behov föreligger så att nytta med insatserna blir olika ska de personliga egenskaperna kunna beaktas i en prioritering på gruppnivå. Frågan om hur externa effekter, d v s effekten av en insats för närstående och andra grupper än den individ som är direkt berörd av insatsen, ska värderas vid en prioritering behöver diskuteras ytterligare.Med behov av hälso- och sjukvård menas både tillståndets svårighetsgrad och den förväntade nyttan av en åtgärd. Som patient har man endast behov av sådana vårdåtgärder som man förväntas ha nytta av. Motsatt gäller att en människa enligt detta sätt att definiera behov inte behöver åtgärder som inte förbättrar hälsan och livskvaliteten, sådana som hon inte har nytta av. Här har givetvis hälso- och sjukvården ett ansvar att lotsa människor de kommer i kontakt med, och som far illa på något sätt, till andra lämpliga aktörer.Riksdagens riktlinjer, när det gäller kostnadseffektivitetsprincipen (tillämpad för enskilda patienter), är för begränsad för att vägleda vid vertikala prioriteringar som gäller prioritering på gruppnivå. Regeringen konstaterade redan i prioriteringspropositionen att det är angeläget att skilja på en kostnadseffektivitetsprincip som gäller val mellan olika åtgärder för den enskilde patienten (där principen kan tillämpas som utredningen föreslår) och på hälso- och sjukvårdens strävan efter en hög kostnadseffektivitet när det gäller vårdens verksamhet i allmänhet. Här stödjer vi oss på Riksdagens direktiv till Läkemedelsförmånsnämnden. Nämnden ska vid beslut om subvention (prioriteringar) av ett läkemedel bl a bedöma om det är kostnadseffektivt i ett samhälleligt perspektiv, vilket innebär att man ställer patientnyttan av läkemedlet mot kostnaden. I bedömningen ska kostnadseffektiviteten vägas samman med behovs- och solidaritetsprincipen och människovärdesprincipen.Den föreslagna arbetsmodellen överensstämmer i allt väsentligt med den arbetsmodell som används av Socialstyrelsens vid framtagning av nationella riktlinjer. Det är inte möjligt att rymma alla aspekter som kan vara aktuella att beakta vid beskrivning av en nationell arbetsmodell. Man måste därför utgå från modellen och fundera på vilka andra relevanta aspekter som dessutom bör vägas in. T ex kan den internationella klassifikationen för funktionsförmåga (ICF) användas som vägledning.På grund av den stora variationsrikedomen av effektmått i olika verksamheter och de begränsade erfarenheter som finns att arbeta med sådana explicita gränsvärden anser vi att det är för tidigt att rekommendera en enhetlig indelning i t ex risknivåer. Det är dock viktigt att de som arbetar med prioriteringar redovisar hur de har resonerat.SBU:s klassifikation för att gradera den vetenskapliga evidensen för en åtgärds effekt bör användas i första hand. Lokala prioriteringsprojekt med begränsade resurser till sitt förfogande föreslås redovisa bedömningen av det vetenskapliga underlaget med ord och referera till det kunskapsunderlag som använts. Evidensstyrkan bör endast uttryckas med siffror då man stöder en slutsats på en systematisk kunskapsöversikt från SBU eller en annan översikt av god kvalitet.Prioriteringsarbeten där hälsoekonomiska data finns tillgängliga bör tills vidare ansluta till Socialstyrelsens arbetssätt och ange kostnadseffektivitet i en skala från låg till mycket hög kostnad per vunnet levnadsår eller kostnad per kvalitetsjusterat levnadsår. Den hälsoekonomiska evidensen bör redovisas i enlighet med de principer som Socialstyrelsen tillämpar. I lokala projekt med små resurser eller svårigheter att konsekvent få fram uppgifter om kostnadseffektivitet rekommenderar vi att man åtminstone resonerar om kostnadseffektivitet i de fall prioriteringsordningen på ett avgörande sätt påverkas när kostnaderna vägs in.Tio nivåer bör användas för rangordning samt att rangordningslistan kompletteras med en ”icke-göra-lista” för metoder som inte bör utföras alls eller rutinmässigt samt en FoU-lista för metoder där det fortfarande saknas tillräcklig evidens för att kunna motivera ett införande i rutinsjukvården. Sammanvägningen sker företrädesvis med en kvalitativ metod i avsaknad av en invändningsfri kvantitativ/matematisk metod. Likaså tror vi att det för närvarade inte är möjligt att fastställa entydiga kriterier som avgör inom vilken rangordningsnivå ett prioriteringsobjekt ska hamna.Resultatet bör presenteras i form av en rangordningslista. De parametrar som ligger till grund för prioriteringen bör också på ett enhetligt sätt redovisas i sådana rangordningslistor som visas för andra. I detalj kan språket och utseendet av pedagogiska skäl behöva anpassas för respektive målgrupp.Gränser för vad som är acceptabel behovstäckning (vårdkvalitet, mängd liksom andel av de i patientgrupp som får tillgång till insatsen) är en regional och lokal fråga och ingår därför inte i den nationella modellen.

(author) Chronically decreased oxygen tension in rat pancreatic islets transplantedunder the kidney capsule 2000 In: Transplantation. - 0041-1337 .- 1534-6080. ; 69:5, s. 761-766 Journal article (peer-reviewed)abstract BACKGROUND: A factor of potential importance in the failure of islet grafts is poor or inadequate engraftment of the islets in the implantation organ. This study measured the oxygen tension and blood perfusion in 1-, 2-, and 9-month-old islet grafts. METHODS: The partial pressure of oxygen was measured in pancreatic islets transplanted beneath the renal capsule of diabetic and nondiabetic recipient rats with a modified Clark electrode (outer tip diameter 2-6 microm). The size of the graft (250 islets) was by purpose not large enough to cure the diabetic recipients. The oxygen tension in islets within the pancreas was also recorded. Blood perfusion was measured with the laser-Doppler technique. RESULTS: Within native pancreatic islets, the partial pressure of oxygen was approximately 40 mm Hg (n=8). In islets transplanted to nondiabetic animals, the oxygen tension was approximately 6-7 mm Hg 1, 2, and 9 months posttransplantation. No differences could be seen between the different time points after transplantation. In the diabetic recipients, an even more pronounced decrease in graft tissue oxygen tension was recorded. The mean oxygen tension in the superficial renal cortex surrounding the implanted islets was similar in all groups (approximately 15 mm Hg). Intravenous administration of glucose (0.1 gxkg(-1)x min(-1)) did not affect the oxygen tension in any of the investigated tissues. The islet graft blood flow was similar in all groups, measuring approximately 50% of the blood flow in the kidney cortex. CONCLUSION: The oxygen tension in islets implanted beneath the kidney capsule is markedly lower than in native islets up to 9 months after transplantation. Moreover, persistent hyperglycemia in the recipient causes an even further decrease in graft oxygen tension, despite similar blood perfusion. To what extent this may contribute to islet graft failure remains to be determined.

46.	Carlsson, Per, 1951-, et al. (author) Prioriteringar inom hälso- och sjukvård - erfarenheter från andra länder 2005 Reports (other academic/artistic)abstract Under de senaste femton åren kan man notera ett uppvaknande hos politiker i flera länder när det gäller behovet av att göra prioriteringar i hälso- och sjukvården. I själva verket har ransonering skett i alla tider. Sådan kan dock föregås av mer eller mindre medvetna och systematiska prioriteringar. När svenska politiker i likhet med sina kollegor i andra länder började prata om behovet av att göra prioriteringar handlade det om att göra dem mer öppet än vad som gällt tidigare. Det har dock visat sig svårt att agera öppet på grund av mängd orsaker. Avsaknaden av enhetliga begrepp, svårt att bestämma vilka kriterier för rättvisa som skall användas och en oförståelse från allmänheten att hälso- och sjukvård ska begränsas på något sätt är exempel på sådana svårigheter. För att övervinna dessa svårigheter har man valt olika strategier i de länder som på allvar försökt göra sina prioriteringar mer öppna. I några länder har man valt att fokusera på att utveckla en gemensam värdegrund medan andra valt att utveckla medborgardialogen. I ytterligare andra länder väljer man att undvika att tala öppet om prioriteringar.I den internationella debatten är det framförallt de amerikanska etikerna Norman Daniels och James Sabin teorier om diskursiv rättvisa som fått ett stort genomslag. De menar att vi aldrig kommer att kunna nå en fullständig enighet om vilka principer som skall gälla vid nödvändiga prioriteringar. Istället anser de att det borde vara möjligt att nå större acceptans om ett prioriteringsbeslut fattats på ett sätt som flertalet anser som legitimt och rättvist. Förutom kravet på öppenhet är det enligt Daniels och Sabin viktigt att grunderna för besluten uppfattas som relevanta. Ett sätt för beslutsfattare att uppnå detta är att alliera sig med andra grupper som åtnjuter viss legitimitet t ex att politiker och vårdpersonal samarbetar. Ett annat sätt kan vara att rationalisera svåra beslut; d v s ge dem karaktär av att vara rationella. Här spelar tillgången på fakta om olika hälso- och sjukvårdsinsatsers effekter och patientnytta en stor roll.Andra forskare menar att prioriteringar av sjukvård alltid innehåller ett stort mått av värderingar och individuella variationer mellan olika patienter. Därför kan man inte grunda sina ställningstaganden på vetenskapliga studier och utarbeta riktlinjer utan istället låta sig styras av vedertagna etiska principer. I Sverige gäller sedan 1997 principen att de med stora behov av vård i första hand skall garanteras vård. Denna princip liksom principen om människors lika värde och kostnadseffektivitet som Riksdagen tagit ställning till är ett försök få igång en bred dialog kring prioriteringar men även att bidra med en plattform för mer öppna och legitima prioriteringar i hälso- och sjukvården. I praktiken visar det sig svårt att omsätta allmänna principer i det dagliga beslutsfattandet.I Sverige efterlyser läkare och andra vårdgrupper tydligare riktlinjer för att kunna ta sitt ansvar för prioriteringar. Den aktuella genomgången visar att man nått olika långt när det gäller öppenheten i de länder som ingår i vår undersökning.Norge var tidigt ute med att utarbeta riktlinjer för prioriteringar inom hälso- och sjukvården. Redan år 1987 avlämnade regeringen en offentlig utredning (NOU 1987:23) i ämnet (Lönning I). Tio år senare återkom regeringen med ytterligare tankar och förslag i NOU 1997:18 (Lönning II). Liksom i alla västländer har den norska hälso- och sjukvårdssektorn haft kostnadsproblem. I synnerhet under 1990-talet tycks kostnaderna ha vuxit i en snabbare takt än vad tillgängliga resurser har tillåtit. En öppen prioritering i enlighet med Lönning-utredningarna tycks dock inte ha varit lösningen på detta dilemma. Genomgången av den norska hälso- och sjukvården ger inget stöd för att dessa tankar fått genomslag i vården. I Norge har man istället försökt lösa problemen med en omfattande strukturförändring som i korthet inneburit att staten genom de regionala hälsoföretagen tagit ett än fastare grepp om den specialiserade sjukhusvården. I de dokument som ligger till grund för den nya ordningen finns dock klara viljeyttringar om att de principer och diskussioner om öppna prioriteringar som finns i både Lönning I och Lönning II ska genomsyra vården framöver. Särskilt omfattande konkret och praktiskt prioriteringsarbete tycks emellertid inte pågå inom ramen för det nya statliga huvudmannaskapet. Införande av en rättighetslag för slutenvård på sjukhus ställer dock krav på en tydligare avgränsning av det offentliga åtagandet. Inte heller inom andra hälso- och sjukvårdssektorer tycks aktiviteterna vara särskilt omfattande.Förändringar av detta slag tar dock lång tid. Det Nationella rådet för prioriteringar inom hälso- och sjukvården som har till uppgift att vara regeringens rådgivande organ ska utveckla principer och metoder för prioriteringar inom hela hälso- och sjukvårdsområdet, både det statliga och det kommunala. Genom rådet har prioriteringsarbetet kommit alltmer i fokus i den omfattande strukturförändring som norsk hälso- och sjukvård genomgår.Nya Zeeland var liksom Norge tidigt med att diskutera prioriteringar inom hälso- och sjukvården på ett öppet och medvetet sätt. I samband med en genomgripande förändring av sjukvårdssystemet i början av 1990-talet påbörjade regeringen ett samtal om gränserna för det offentliga åtagandet och behovet av prioriteringar. Man valde metoder som involverade både sjukvårdspersonal och medborgare. Drygt tio år senare kan man konstatera att det nya zeeländska försöket bara delvis realiserats. Prioriteringar som var tänkta att göras genom att definiera en kärna av sjukvårdstjänster som skulle finansieras offentligt utifrån fastställda kriterier kom aldrig riktigt till stånd.Ekonomin vände, en regering med en annan majoritet tillträdde år 1999 och hälso- och sjukvårdssektorn tillfördes ytterligare medel. Under de första åren på 2000-talet har sjukvården blivit tillförsäkrad resurser motsvarande en utgiftsökning för staten med 21 procent på tre år. Intresset för att diskutera prioriteringar och rättvisefrågor har därmed falnat.Samtidigt kan man konstatera att diskussionen och det arbete som lades ner från början av 1990-talet och framåt har haft viss effekt. Det finns idag en medvetenhet om att det är nödvändigt att se över hur åtminstone tillskottet av resurser som sektorn tilldelas ska fördelas. Arbete pågår både centralt i Ministry of Health och regionalt i de nytillskapade District Health Boards att finna metoder och fördelningsnycklar för hur nytillskottet av pengar ska användas på bästa sätt med de fyra prioriteringskriterierna som formulerades redan i början av 90-talet som grund. Samtalet med befolkningen fortsätter i nya former i första hand genom de nya distriktsstyrelserna.Storbritannien uppvisar relativt låga ambitioner när det gäller att utveckla former för öppna prioriteringar. Det beror dels på att majoriteten av sjukvård fördelas genom en politiskt styrd organisation och dels på den starka symboliska roll som National Health Service (NHS) intar i det brittiska samhället. NHS är en av få organisationer i ett ganska ojämlikt samhälle som alltid har stått för principen om jämlikhet – vård efter behov och inte betalningsförmåga. Det har därför varit särskilt känsligt för politikerna på den nationella nivån att öppet diskutera att utesluta vissa vårdåtgärder.På den lokala nivån inom den offentliga sjukvården har dock beslutsfattare prövat olika former för en mer öppen prioritering. Det finns ingen klar linje utan det förekommer stora lokala variationer, där vissa sjukvårdsområden försökt gå i riktning mot en tydlig process där motiven bakom prioriteringar tydliggörs för allmänheten. Hur framtiden kommer att te sig i detta avseende är svårt att uttala sig om då den lokala beställarorganisationen befinner sig i en period av omställning, där de läkardominerade Primary Care Trusts håller på att ta över ansvaret från de traditionella ”health authorities”.Den nuvarande brittiska regeringen har valt en strategi för att lösa brister i NHS med mer pengar och effektivisering. I fallet med prioriteringar har politikerna lämnat över ansvaret till allehanda expertorgan, helt i linje med uppfattningen att god evidens ska leda till mer självklara avvägningar inom den lokala sjukvården. I vilken utsträckning den verksamhet som bedrivs inom expertorganet NICE kommer att underlätta prioriteringar är dock oklart. En effekt blir också att den lokala sjukvården måste implementera de nya medicinska metoder som av NICE bedöms vara kostnadseffektiva. Att detta leder till att nya prioriteringar aktualiseras är givet.NICE löser inte det grundläggande dilemma som en heltäckande offentlig sjukvårdsorganisation, som brittiska NHS, står inför, nämligen att kraven på organisationen tenderar att hela tiden öka. Trots en del försök med konsultation av medborgare i frågor om prioritering finns dock inget som tyder på att den brittiska allmänheten stöder uppfattningen att den offentliga hälso- och sjukvården måste begränsa sitt åtagande.Liksom i flera andra länder väcktes frågan om öppna prioriteringar i Nederländerna under en tid av dålig offentlig ekonomi. På samma sätt som i Sverige mynnade diskussionen ut i ett politiskt dokument med höga ambitioner rörande öppenhet och prioriteringsprinciper (den s k Dunningkommitténs slutrapport). Trots vissa försök att begränsa det samhälleliga åtagandet inom hälso- och sjukvården har de flesta tjänster som genom politiska beslut lyfts ut ur förmånssystemet lyfts tillbaka igen efter påtryckningar. Kostnadskontrollen har följd

Men who underwent RT were older (69 vs 65 yr) and had more comorbidities at baseline. After RARP, 13% of men experienced incontinence, compared to 6% after RT. The frequency of urinary bother was similar, at 18% after RARP and 18% after RT. Urgency to defecate was reported by 14% of men after RARP and 34% after RT. At 1 yr, 73% of men had ED after RARP, and 77% after RT. High QoL was reported by 85% of men after RARP and 78% of men after RT. On multivariable regression analysis, RT was associated with lower risks of urinary incontinence (OR 0.25, 95% confidence interval [CI] 0.19-0.33), urinary bother (OR 0.79, 95% CI 0.66-0.95), and ED (OR 0.54, 95% CI 0.46-0.65), but higher risk of bowel symptoms (OR 2.86, 95% CI 2.42-3.39). QoL was higher after RARP than after RT (OR 1.34, 95% CI 1.12-1.61).CONCLUSIONS: Short-term specific side effects after curative treatment for prostate cancer significantly differed between RARP and RT in this large and unselected cohort. Nevertheless, the risk of urinary bother was lower after RT, while higher QoL was common after RARP.PATIENT SUMMARY: In our study of patients treated for prostate cancer, urinary bother and overall quality of life are comparable at 1 year after surgical removal of the prostate in comparison to radiotherapy, despite substantial differences in other side effects.
