God havsmiljö 2020 : Marin strategi för Nordsjön och Östersjön Del 2: God miljöstatus och miljökvalitetsnormer
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Havsmiljöförordningens övergripande mål är att upprätthålla eller uppnå en god miljöstatus i de svenska förvaltningsområdena Nordsjön och Östersjön till år 2020. En av uppgifterna i den första förvaltningsperioden är att bestämma vad som kännetecknar god miljöstatus i respektive förvaltningsområde samt att ta fram miljökvalitetsnormer. God miljöstatus baseras på ett ramverk av så kallade deskriptorer som anges i havsmiljödirektivet, det vill säga det EU-direktiv som i Sverige genomförs genom havsmiljöförordningen. Deskriptorerna beskriver god miljöstatus på en övergripande nivå för 11 temaområden. Till varje deskriptor hör en rad kriterier som anger vad som ska ingå i en bedömning av miljöstatus. I Sverige har god miljöstatus formulerats för samtliga 29 kriterier som ska beaktas enligt direktivet. Dessa kvalitativa beskrivningar anger vad som kännetecknar god miljöstatus i Nordsjön och Östersjön. För att praktiskt bedöma om god miljöstatus har uppnåtts föreslås 37 nationella indikatorer. En uppsättning av indikatorer omfattar miljöns tillstånd och avspeglar ekosystemets komponenter i form av nyckelarter, samhällen, och livsmiljöer. En utgångspunkt vid val av indikatorer för miljöns tillstånd har varit koppling till de belastningar som i den inledande bedömningen av miljötillståndet i Nordsjön och Östersjön bedömts ha stor negativ påverkan på ekosystemet. En annan uppsättning indikatorer berör påverkan och belastning på miljön i form av tillförsel av näringsämnen och farliga ämnen, samt biologisk och fysisk störning av miljön. Tillsammans utgör indikatorerna ett verktyg för att följa utvecklingen av miljötillståndet och effekter av åtgärder i havsmiljön. Vid val av indikatorer har arbetet delvis utgått från existerande miljöövervakning och redan utvecklade indikatorer. Med denna utgångspunkt uppfylls en rad av havsmiljödirektivets krav, bland annat en god uppföljning av effekter av tillförsel av näringsämnen. Funktionella indikatorer, det vill säga indikatorer som utvärderats och för vilka god miljöstatus har definierats, saknas dock för tio av havsmiljödirektivets 29 kriterier. För uppföljning av biologisk mångfald saknas bland annat miljöövervakning och metoder för att bedöma livsmiljöers tillstånd. För att kunna bedöma fysiska skador på havsbotten saknas en övergripande sammanställning av information om aktiviteter som påverkar havsbottnar samt metodik för att bedöma effekterna. Det saknas också utvecklade indikatorer för det kriterium som berör uppföljning av storleks- och åldersstruktur hos fiskar. Brist på kunskap gör också att inga förslag på svenska indikatorer kan ges för effekter på levande organismer från marint avfall, undervattensbuller, och främmande arter samt att endast ett begränsat antal indikatorer tagits fram som speglar effekter av farliga ämnen. De indikatorer som fastställs i juli 2012 utgör således inte en slutlig lista för att följa upp havsmiljödirektivet. Bristerna kommer att beaktas i det fortsatta genomförandet av havsmiljöförordningen där nästa steg är att anpassa miljöövervakningsprogrammen till uppföljning av miljötillståndet med valda indikatorer senast år 2014 samt att ta fram åtgärdsprogram till år 2015. God miljöstatus ska uppnås genom tillämpning av miljökvalitetsnormer det vill säga rättsligt bindande regler som avspeglar den lägsta godtagbara miljökvaliteten i Nordsjön och Östersjön. För att nå god miljöstatus har elva svenska miljökvalitetsnormer formulerats. Dessa miljökvalitetsnormer omfattar belastning i form av näringsämnen, farliga ämnen, främmande arter, uttag av arter, fysisk påverkan på havsbottnar och avfall i havsmiljön. Målsättningen har varit att utforma miljökvalitetsnormer som motsvarar alla de belastningar som i den inledande bedömningen har identifierats ha en stor påverkan på miljön.

Kulturhistoriska värden i ett förändrat klimat. Hot, risker och hanteringkopplat till vägar och banor
- 2021
-
Rapport (refereegranskat)abstract
- Klimatförändringar utgör en bred palett av risker för kulturmiljö och landskap,inklusive de kulturhistoriska lämningar som har en nära eller direkt kopplingtill transportinfrastruktur. I detta projekt tittade vi på ett antal av dessa riskeri syfte att hjälpa Trafikverket att utveckla tjänster för bättre förutsägelse ochhantering av riskerna i anslutning till vägar och banor. Forskningen inleddesgenom en översikt av befintliga offentliga publikationer om klimatförändringenshot, risker, metoder, anpassningsåtgärder och kulturmiljö. Detta följdesav en undersökning av upplevelsen av dessa frågor bland offentligt anställdaexperter som medverkar i planeringen. Geografiska informationssystem (GIS)användes för att identifiera kulturhistoriska lämningar som är klimatologisktriskutsatta sig i riskzonen för tre undersökningsområden, följt av fältbesökför att bedöma tillförlitligheten i GIS-resultaten. Analysen visade att en enkelGIS-analys kan vara till hjälp för att identifiera riskutsatta platser, men ocksåatt fältarbete kan medverka till att identifiera ytterligare risker men också problemmed noggrannheten i underliggande datamaterial. Projektet tillhandahållerockså grundläggande statistik om i vilken utsträckning olika typer avkulturhistoriska lämningar på nationell nivå riskerar att hotas enligt nuvarandeklimatförändringsmodeller. Projektet genomförde också fallstudier av 1) vägsaltetsrisker för milstolpar och andra arkeologiska företeelser i anslutning tillvägar, och 2) de historiska kartornas potential att användas för att identifierariskutsatta områden vid framtida klimatförändringar. Slutligen diskuteras konsekvensernaav dessa resultat för prioriteringar av klimatanpassningsaktivitetersamt presenterar förslag på metoder och modeller för att identifiera transportinfrastrukturenskulturmiljöer som är hotas av klimatförändringar.

Entrepreneurship in a School Setting : Introducing a Business Concept in a Public Context
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Entrepreneurship has during the last decades gained an immense interest in academia, politics and practice. It is argued from politics that more entrepreneurs are necessary for the economic development. In addition, nowadays entrepreneurship is also perceived as a solution to social and societal challenges. This drives a need for entrepreneurial people everywhere in society who can cope with the inconstant and uncertain world of today. As a consequence, there are around the world numerous educational initiatives trying to inspire and fuel an entrepreneurial mind-set. Here, educations of all kind become relevant contexts since they provide an opportunity to affect children, youth’s and adult’s interest and attitudes towards entrepreneurship, and as such give a possibility to reach a vast number of people.Sweden is no exception, and in 2009 the Swedish Government launched a ‘Strategy for entrepreneurship in the field of education’ in which entrepreneurship is said to run like a common thread throughout education. The main focus is that self-employment is to become as natural as being an employee. As such the Government took an active stand for implementing entrepreneurship in the school setting on a broad front, from preschool to adult education.This development can be seen as part of New Public Management; a development where concepts from the private sector are lent and transferred to the public sector. Thus, when introducing entrepreneurship in the Swedish educational system, this at the same time means introducing a traditional business concept in a public setting. Therefore, the overall aim of this thesis is to increase knowledge of and insights on how a business concept – entrepreneurship – is operationalised and constructed in a public setting.When placing entrepreneurship in new societal contexts other questions arise and complexity intensifies. In this qualitative research, the empirical context in focus are schools. It investigates how entrepreneurship is constructed among teachers in their work. But also how this business concept is included in a non-business setting by studying how the entrepreneurship strategy is operationalised in educational practice.As such the thesis and its findings contribute to the scientific discussions on societal entrepreneurship and entrepreneurship education, as well as on strategy and strategising in a public context. The research also aspire to serve inspiration, insights and food for thoughts on discussions and reflections on entrepreneurship within the school practice. This compilation thesis include five papers. To be able to fulfil the aim this research use a broad theoretical base and multiple qualitative research methods. The combination of methods include semi-structured interviews, in-depth interview using the stimulated recall method, focus group interviews, participative meetings, observations, document studies, digital questionnaires, written inquiries, analysing texts and critical incidents questionnaires.

Affinity tags can reduce merohedral twinning of membrane protein crystals
- 2008

Tidskriftsartikel (refereegranskat)abstract
- This work presents a comparison of the crystal packing of three eukaryotic membrane proteins: human aquaporin 1, human aquaporin 5 and a spinach plasma membrane aquaporin. All were purified from expression constructs both with and without affinity tags. With the exception of tagged aquaporin 1, all constructs yielded crystals. Two significant effects of the affinity tags were observed: crystals containing a tag typically diffracted to lower resolution than those from constructs encoding the protein sequence alone and constructs without a tag frequently produced crystals that suffered from merohedral twinning. Twinning is a challenging crystallographic problem that can seriously hinder solution of the structure. Thus, for integral membrane proteins, the addition of an affinity tag may help to disrupt the approximate symmetry of the protein and thereby reduce or avoid merohedral twinning.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to evaluate the effect of psychosocial rehabilitation on newly diagnosed prostate cancer patients. The “Between Men” programme consisted of seven weekly sessions of physical training (Phys) alone, information (Info) alone or physical training plus information (PhysInfo). After diagnoses, patients (n =211) were consecutively included, stratified and randomised to one of four groups: Phys, Info, PhysInfo or standard care control (C). A nurse specialised in urology, an urologist and a physiotherapist performed the interventions. Patients were followed up during one year with mailed standardised questionnaires. It could not be assumed that the “Between Men” programme had any effect on patients’ anxiety and depression (HADS). Health-related quality of life (HRQOL) was associated with stage of disease but not with psychosocial intervention. Thus, Physical Function (PF), Role Function (RF) and Fatigue (FA) were inferior among patients with, than without, metastases of prostate cancer both at baseline and at the 12-month follow-up. This randomized study did not demonstrate any significant effect of psychosocial rehabilitation among prostate cancer patients. Considering the low rate (1/2), of included/eligible patients a less complicated design (intervention versus control) would have been preferred in order to increase power.

Övervakning av metaller och organiska miljögifter i marin biota, 2011

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The environmental toxicants examined in this report can be classified into five groups –heavy metals, chlorinated compounds, brominated flame retardants, polyaromatichydrocarbons and perfluorinated compounds. Each of these contaminants has beenexamined from various sites for up to six different fish species, in blue mussels, and inguillemot eggs, for varying lengths of time. The following summary examines overalltrends, spatial and temporal, for the five groups.Condition and Fat ContentCondition and fat content in different species tended to follow the same pattern at the samesites, with a few exceptions. Most of the fish species generally displayed a decreasing trendin both condition and fat content at most sites examined. Exceptions to this were increasesin fat content seen in herring (the last ten years) and cod at Fladen; an increase in conditionfor herring at Ängskärsklubb in spring; and in perch, a decrease in fat content atKvädöfjärden but no trend in condition for the same site.Heavy MetalsDue to a change in methods for metal analysis (not Hg) in 2004, values between 2003 and2007 should be interpreted with care. From 2009 metals are analyzed at ITM, Stockholmuniversity.The longer time series in guillemot egg and spring-caught herring from the southernBothnian Sea and southern Baltic Proper show significant decreases of mercury. Theherring site in the southern Bothnain Sea indicates a local Hg-source. The rest of the timeseries show varying concentrations over the study period, and even increasing trends in e.g.cod muscle and blue mussels, but the concentrations are fairly low compared to measuredconcentrations in perch from fresh water and coastal sites. However, in most cases, theseconcentrations are above the newly suggested EU-target level of 20 ng/g wet weight.Lead is generally decreasing over the study period (in time series of sufficient length),supposedly due to the elimination of lead in gasoline. Elevated lead concentrations between2003 and 2007 (e.g. Harufjärden) should be viewed with caution (see above regardingchange in analysis methods).Cadmium concentrations show varying non-linear trends over the monitored period. It isworth noting that despite several measures taken to reduce discharges of cadmium,generally the most recent concentrations are similar to concentrations measured 30 yearsago in the longer time series.The reported nickel concentrations show no consistent decreasing trends. Some series beginwith two elevated values that exert a strong leverage effect on the regression line and maygive a false impression of decreasing trends. Chromium generally shows decreasing trends,possibly explained by a shift in analytical method. The essential trace metals, copper andzinc, show no consistent trends during the monitored period.

The histone deacetylase inhibitor trichostatin A reduces lysosomal pH and enhances cisplatin-induced apoptosis
- 2013

Ingår i: Experimental Cell Research. - : Elsevier. - 0014-4827 .- 1090-2422. ; 319:1, s. 12-20

Tidskriftsartikel (refereegranskat)abstract
- High activity of histone deacetylases (HDACs) has been documented in several types of cancer and may be associated with survival advantage. In a head and neck squamous cell carcinoma cell line, cisplatin-induced apoptosis was augmented by pretreatment with the HDAC inhibitor trichostatin Apoptosis was accompanied by lysosomal membrane permeabilization (LMP), as shown by immunoblotting of the lysosomal marker protease cathepsin B in extracted cytosol and by immunofluorescence. Moreover, LAMP-2 (lysosomal associated membrane protein-2) was translocated from lysosomal membranes and found in a digitonin extractable fraction together with cytosolic proteins and pretreatment with trichostatin A potentiated the release. Overall, protein level of LAMP-2 was decreased during cell death and, interestingly, inhibition of cysteine cathepsins, by the pan-cysteine cathepsin inhibitor zFA-FMK, prevented loss of LAMP-2. The importance of LAMP-2 for lysosomal membrane stability, was confirmed by showing that LAMP-2 knockout MEFs (mouse embryonic fibroblasts) were more sensitive to cisplatin as compared to the corresponding wildtype cells. Trichostatin A reduced lysosomal pH from 4.46 to 4.25 and cell death was prevented when lysosomal pH was increased by NH4Cl, or when inhibiting the activity of lysosomal proteases. We conclude that trichostatin A enhances cisplatin induced cell death by decreasing lysosomal pH, which augments cathepsin activity resulting in reduced LAMP-2 level, and might promote LMP.

Tidskriftsartikel (refereegranskat)abstract
- Radiofrequency (RF) generated thermal brain lesions are widely used in functional neurosurgery. The size, shape and development of the lesions depends on system parameter settings and the electrode configuration. Difficulties in studying the effect of these factors in vivo stimulated us to develop an in vitro system for standardized comparison between different electrodes and physical parameters. A computer-assisted video system was set-up allowing continuous video recording of RF-generated coagulations in either a standard albumin solution or in the fresh white of a hen's egg as transparent test substrates. Ten lesions were made with each test electrode (two bipolar and three monopolar) in each of the two substrates at 70 degrees, 80 degrees and 90 degrees C (t = 60 sec). Due to the better homogeneity the lesions in the albumin solution were much more regular and reproducible. This made it possible to calculate the size (width 2.2 +/- 0.1 to 5.3 +/- 0.1 mm and length 3.0 +/- 0.1 to 8.7 +/- 0.3 mm) as well as the volume (8.5 +/- 1.4 mm3 to 133.5 +/- 26.8 mm3). It is concluded that this in vitro system offers a reproducible way to study and document the effect of different electrode configurations and RF-generator settings on the formation of a heat lesion. Even if the results are not directly applicable to the living human brain they give an estimate of the form and size of a coagulation lesion and can be of value for standardized comparisons between different electrodes.

NMR quantification of diffusional exchange in cell suspensions with relaxation rate differences between intra and extracellular compartments

Tidskriftsartikel (refereegranskat)abstract
- Water transport across cell membranes can be measured non-invasively with diffusion NMR. We present a method to quantify the intracellular lifetime of water in cell suspensions with short transverse relaxation times, T2, and also circumvent the confounding effect of different T2 values in the intra- and extracellular compartments. Filter exchange spectroscopy (FEXSY) is specifically sensitive to exchange between compartments with different apparent diffusivities. Our investigation shows that FEXSY could yield significantly biased results if differences in T2 are not accounted for. To mitigate this problem, we propose combining FEXSY with diffusion-relaxation correlation experiment, which can quantify differences in T2 values in compartments with different diffusivities. Our analysis uses a joint constrained fitting of the two datasets and considers the effects of diffusion, relaxation and exchange in both experiments. The method is demonstrated on yeast cells with and without human aquaporins.

Accidents between cyclists and heavy vehicles turning right : conflict and behavioral studies in intersections in central Stockholm
- 2016
-
Konferensbidrag (refereegranskat)abstract
- This study aimed to find ways to decrease the risk for severe accidents between cyclists and heavy vehicles turning right. The primary question was whether the so called “Dutch” intersection design (with a protecting curb) could decrease the risks. Other questions were if there are other/better methods/designs and if there will be new serious risks with the Dutch design. The result from this study is that the Dutch design doesn't protect from accidents between cars turning right and cyclist. The reason for this is that these accidents mainly involve cyclists going straight. The best designs are where right turning cars have red signal while cyclists going straight have green signal. Other good solutions are bicycle lane together with bicycle box or set-back stop line for the cars. Bicycle tracks should transform into lanes when approaching an intersection. The study not only found that the Dutch design is a poor design to protect from car/bicycle accidents; it also brings new risks for accidents between cyclists and pedestrians.

The Tumor Targeted Superantigen ABR-217620 Selectively Engages TRBV7-9 and Exploits TCR-pMHC Affinity Mimicry in Mediating T Cell Cytotoxicity.
- 2013
-
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 8:10

Tidskriftsartikel (refereegranskat)abstract
- The T lymphocytes are the most important effector cells in immunotherapy of cancer. The conceptual objective for developing the tumor targeted superantigen (TTS) ABR-217620 (naptumomab estafenatox, 5T4Fab-SEA/E-120), now in phase 3 studies for advanced renal cell cancer, was to selectively coat tumor cells with cytotoxic T lymphocytes (CTL) target structures functionally similar to natural CTL pMHC target molecules. Here we present data showing that the molecular basis for the anti-tumor activity by ABR-217620 resides in the distinct interaction between the T cell receptor β variable (TRBV) 7-9 and the engineered superantigen (Sag) SEA/E-120 in the fusion protein bound to the 5T4 antigen on tumor cells. Multimeric but not monomeric ABR-217620 selectively stains TRBV7-9 expressing T lymphocytes from human peripheral blood similar to antigen specific staining of T cells with pMHC tetramers. SEA/E-120 selectively activates TRBV7-9 expressing T lymphocytes resulting in expansion of the subset. ABR-217620 selectively triggers TRBV7-9 expressing cytotoxic T lymphocytes to kill 5T4 positive tumor cells. Furthermore, ABR-217620 activates TRBV7-9 expressing T cell line cells in the presence of cell- and bead-bound 5T4 tumor antigen. Surface plasmon resonance analysis revealed that ABR-217620 binds to 5T4 with high affinity, to TRBV7-9 with low affinity and to MHC class II with very low affinity. The T lymphocyte engagement by ABR-217620 is constituted by displaying high affinity binding to the tumor cells (KD approximately 1 nM) and with the mimicry of natural productive immune TCR-pMHC contact using affinities of around 1 µM. This difference in kinetics between the two components of the ABR-217620 fusion protein will bias the binding towards the 5T4 target antigen, efficiently activating T-cells via SEA/E-120 only when presented by the tumor cells.

Pros and cons of transdisciplinary research: A case study of Swedish lawns and their sustainable alternatives
- 2020
-
Ingår i: Urban Forestry & Urban Greening. - : Elsevier BV. - 1618-8667 .- 1610-8167. ; 56

Tidskriftsartikel (refereegranskat)abstract
- In this article, we discuss the pros and cons of transdisciplinary research using the results of a research project on lawns carried out in Sweden from 2013 to 2016. We viewed lawns as a complex ecological and cultural phenomenon and searched for different sustainable lawn solutions in urban areas of Sweden.Constraints on the research included the time and effort required for team members to become familiar with the different research approaches, participate in regular meetings and agree on joint methodology. Later in the project, the integration, analysis and understanding of field data, theoretical sources and practical implementation approaches were also time-consuming obstacles. Thus, the initial and final phases of the project were extremely important and demanded a lot of time and effort. Especially challenging was the cross-use of different methodologies from natural and social sciences. Such ambitious multiscale and multitask projects dealing with living urban nature and people require at least five years to complete, rather than the three years typically suggested for classical research projects.The pros of the transdisciplinary approach was its ability to incorporate results of natural and social studies into landscape design, the ability to involve stakeholders in different project activities and to disseminate the research results in practice. This research revealed that lawns are a relatively recent phenomenon that is still expanding globally. The social study component showed that mowing and creating smooth, green lawn surfaces is important to stakeholders (lawn users, planners and managers). However, in Sweden, there is a tendency for local citizens to accept more biodiverse plant communities. Working closely with open-minded stakeholders led to the real implementation of lawn alternatives, which, in turn, increased media attention. The initial concept—that management was a central factor to the whole transdisciplinary project—was confirmed. The goal of this article is to share the unique experiences and lessons learned by researchers of conducting transdisciplinary research and to make such complex research more successful.

Tidskriftsartikel (refereegranskat)abstract
- AIM: The aim of this study was to describe Child Health Service (CHS) nurses' experiences with conducting individual parental conversations (IPCs) with non-birthing parents. BACKGROUND: CHS nurses in Sweden mainly focus on monitoring a child's physical and mental development and the mothers' health in order to support their parenthood. The assignment of the CHS includes identifying dysfunctional social relationships in a family and strengthening responsive parenting. An imbalance arises within the family when someone in the family suffers from illness, which could have a negative effect on the whole family's health and well-being. METHODS: An inductive, descriptive qualitative study design was used to describe and to gain an understanding of the CHS nurses' experiences. Data were collected in 13 interviews, and a qualitative content analysis was performed. FINDINGS: The analysis of interviews with CHS nurses resulted in two main categories, each with three subcategories. The main categories are: working for equality and applying a family focus, and dealing with challenges in the developing assignment. The IPCs stimulate the CHS nurses to work for more equality and to apply a family focus, which can be a way of strengthening the families' health and the children's upbringing. Developing the CHS nurses' assignment can be a challenge that appears to entail positive outcomes for CHS nurses, while also generating the need for CHS nurses to receive supervision to find ways to improve their approach and practice.

Tidskriftsartikel (refereegranskat)abstract
- Obesity is heritable and predisposes to many diseases. To understand the genetic basis of obesity better, here we conduct a genome-wide association study and Metabochip meta-analysis of body mass index (BMI), a measure commonly used to define obesity and assess adiposity, in up to 339,224 individuals. This analysis identifies 97 BMI-associated loci (P < 5 × 10(-8)), 56 of which are novel. Five loci demonstrate clear evidence of several independent association signals, and many loci have significant effects on other metabolic phenotypes. The 97 loci account for ∼2.7% of BMI variation, and genome-wide estimates suggest that common variation accounts for >20% of BMI variation. Pathway analyses provide strong support for a role of the central nervous system in obesity susceptibility and implicate new genes and pathways, including those related to synaptic function, glutamate signalling, insulin secretion/action, energy metabolism, lipid biology and adipogenesis.

Quantification of the Intracellular Life Time of Water Molecules to Measure Transport Rates of Human Aquaglyceroporins

-

Tidskriftsartikel (refereegranskat)abstract
- Orthodox aquaporins are transmembrane channel proteins that facilitate rapid diffusion of water, while aquaglyceroporins facilitate the diffusion of small uncharged molecules such as glycerol and arsenic trioxide. Aquaglyceroporins play important roles in human physiology, in particular for glycerol metabolism and arsenic detoxification. We have developed a unique system applying the strain of the yeast Pichia pastoris, where the endogenous aquaporins/aquaglyceroporins have been removed and human aquaglyceroporins AQP3, AQP7, and AQP9 are recombinantly expressed enabling comparative permeability measurements between the expressed proteins. Using a newly established Nuclear Magnetic Resonance approach based on measurement of the intracellular life time of water, we propose that human aquaglyceroporins are poor facilitators of water and that the water transport efficiency is similar to that of passive diffusion across native cell membranes. This is distinctly different from glycerol and arsenic trioxide, where high glycerol transport efficiency was recorded.

- Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.

Hur mår samer i Sverige? : Resultat från en enkätundersökning om hälsa, livsvillkor och levnadsvanor bland samer
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I den här rapporten presenterar vi resultat från enkätundersökningen Samisk hälsapå lika villkor. Den genomfördes under våren 2021 och besvarades av 3 658 sameri åldern 18–84 år i Sverige. Syftet med rapporten är att översiktligt beskriva hälsa,livsvillkor och levnadsvanor bland samer. Resultaten har även jämförts medbefolkningen i övrigt genom data från den nationella folkhälsoenkäten Hälsa pålika villkor, också den genomförd under våren 2021.Resultaten i korthetDe flesta samer i den här studien, 73 procent, uppger att de har en god allmänhälsa. Nästan alla, 87 procent, har ett gott psykiskt välbefinnande. Totalt 41 procentav samerna uppger att de har en långvarig sjukdom eller funktionsnedsättning.Andelen som uppger att de röker dagligen är 4 procent, och andelen som snusar 23procent.Jämförelsen mellan samer och befolkningen i övrigt visar följande:• En lika stor andel samer som befolkningen i övrigt uppger en god allmänhälsa. Även andelen samer som uppger sjukdomar som högt blodtryck ochdiabetes eller psykiska besvär som ängslan, oro eller ångest är lika stor som ibefolkningen i övrigt.• En mindre andel samer än befolkningen i övrigt uppger sömnsvårigheter,trötthet och psykisk påfrestning. Det är också en mindre andel samer somuppger att de är stillasittande mer än tio timmar per dag, har en riskkonsumtionav alkohol, uppger att de röker dagligen eller att de någon gång har använtcannabis.• En mindre andel samer jämfört med befolkningen i övrigt uppger bra tandhälsaoch att de äter frukt och grönsaker minst en gång per dag.• En större andel samer än befolkningen i övrigt har ett gott psykisktvälbefinnande. Däremot uppger en större andel samer att de har en långvarigsjukdom eller funktionsnedsättning, värk i olika delar av kroppen, astma,allergi, övervikt och fetma. Även andelen samer som uppger att de snusardagligen är större än i befolkningen i övrigt.• En större andel samer än befolkningen i övrigt uppger att de någon gångallvarligt övervägt att ta sitt liv eller att de någon gång försökt att ta sitt liv.Vidare är det en större andel samer som uppger att de har haft svårt att klara delöpande utgifterna under de senaste 12 månaderna. Andelen samer som uppgeratt de någon gång under de senaste 3 månaderna blivit behandlade ellerbemötta så att de har känt sig kränkta är större än i befolkningen i övrigt.Vad gäller covid-19-pandemin, uppger en mindre andel samer än befolkningen iövrigt att de har testat positivt för covid-19. Däremot uppger en större andel sameratt de har varit oroliga för att de själva eller någon närstående ska bli allvarligt sjuk. 8Samers hälsa behöver fortsatt följasDen här kartläggningen är ett första viktigt steg för att följa hälsosituationen blandsamer i Sverige och är en av de mest omfattande enkätundersökningar som hargenomförts hittills. Studien bidrar till viktig kunskap om samers hälsa, livsvillkoroch levnadsvanor och kan ligga till grund både för fortsatt kunskapsutveckling ochutformning av hälsofrämjande och förebyggande insatser på lokal, regional ochnationell nivå. Det behövs även fortsatta och fördjupade analyser med särskiltfokus på olika grupper bland samer som kan ha sämre hälsa eller sämreförutsättningar för en god hälsa.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Subarachnoid haemorrhage (SAH) is a devastating disease, with high mortality rate and substantial disability among survivors. Its causes are poorly understood. We aimed to investigate risk factors for SAH using a novel nationwide cohort consortium.METHODS: We obtained individual participant data of 949 683 persons (330 334 women) between 25 and 90 years old, with no history of SAH at baseline, from 21 population-based cohorts. Outcomes were obtained from the Swedish Patient and Causes of Death Registries.RESULTS: During 13 704 959 person-years of follow-up, 2659 cases of first-ever fatal or non-fatal SAH occurred, with an age-standardized incidence rate of 9.0 [95% confidence interval (CI) (7.4-10.6)/100 000 person-years] in men and 13.8 [(11.4-16.2)/100 000 person-years] in women. The incidence rate increased exponentially with higher age. In multivariable-adjusted Poisson models, marked sex interactions for current smoking and body mass index (BMI) were observed. Current smoking conferred a rate ratio (RR) of 2.24 (95% CI 1.95-2.57) in women and 1.62 (1.47-1.79) in men. One standard deviation higher BMI was associated with an RR of 0.86 (0.81-0.92) in women and 1.02 (0.96-1.08) in men. Higher blood pressure and lower education level were also associated with higher risk of SAH.CONCLUSIONS: The risk of SAH is 45% higher in women than in men, with substantial sex differences in risk factor strengths. In particular, a markedly stronger adverse effect of smoking in women may motivate targeted public health initiatives.

Perilipin 1 binds to aquaporin 7 in human adipocytes and controls its mobility via protein kinase A mediated phosphorylation

Tidskriftsartikel (refereegranskat)abstract
- Accumulating evidence suggests that dysregulated glycerol metabolism contributes to the pathophysiology of obesity and type 2 diabetes. Glycerol efflux from adipocytes is regulated by the aquaglyceroporin AQP7, which is translocated upon hormone stimulation. Here, we propose a molecular mechanism where the AQP7 mobility in adipocytes is dependent on perilipin 1 and protein kinase A. Biochemical analyses combined with ex vivo studies in human primary adipocytes, demonstrate that perilipin 1 binds to AQP7, and that catecholamine activated protein kinase A phosphorylates the N-terminus of AQP7, thereby reducing complex formation. Together, these findings are indicative of how glycerol release is controlled in adipocytes, and may pave the way for the future design of drugs against human metabolic pathologies.

Exposure to long-term source-specific transportation noise and incident breast cancer : A pooled study of eight Nordic cohorts
- 2023
-
Ingår i: Environment International. - : Elsevier. - 0160-4120 .- 1873-6750. ; 178
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Environmental noise is an important environmental exposure that can affect health. An association between transportation noise and breast cancer incidence has been suggested, although current evidence is limited. We investigated the pooled association between long-term exposure to transportation noise and breast cancer incidence.Methods: Pooled data from eight Nordic cohorts provided a study population of 111,492 women. Road, railway, and aircraft noise were modelled at residential addresses. Breast cancer incidence (all, estrogen receptor (ER) positive, and ER negative) was derived from cancer registries. Hazard ratios (HR) were estimated using Cox Proportional Hazards Models, adjusting main models for sociodemographic and lifestyle variables together with long-term exposure to air pollution.Results: A total of 93,859 women were included in the analyses, of whom 5,875 developed breast cancer. The median (5th–95th percentile) 5-year residential road traffic noise was 54.8 (40.0–67.8) dB Lden, and among those exposed, the median railway noise was 51.0 (41.2–65.8) dB Lden. We observed a pooled HR for breast cancer (95 % confidence interval (CI)) of 1.03 (0.99–1.06) per 10 dB increase in 5-year mean exposure to road traffic noise, and 1.03 (95 % CI: 0.96–1.11) for railway noise, after adjustment for lifestyle and sociodemographic covariates. HRs remained unchanged in analyses with further adjustment for PM2.5 and attenuated when adjusted for NO2 (HRs from 1.02 to 1.01), in analyses using the same sample. For aircraft noise, no association was observed. The associations did not vary by ER status for any noise source. In analyses using <60 dB as a cutoff, we found HRs of 1.08 (0.99–1.18) for road traffic and 1.19 (0.95–1.49) for railway noise.Conclusions: We found weak associations between road and railway noise and breast cancer risk. More high-quality prospective studies are needed, particularly among those exposed to railway and aircraft noise before conclusions regarding noise as a risk factor for breast cancer can be made.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Long-term sickness absence is one of the main risk factors for permanent exit out of the labour market. Early identification of the condition is essential to facilitate return to work. The aim of this study was to analyse possible determinants of return to work and their relative impact.METHODS:All 943 subjects aged 18 to 63 years, sickness certified at a Primary Health Care Centre in Sweden from 1 January until 31 August 2004, were followed up for three years. Baseline information on sex, age, sick leave diagnosis, employment status, extent of sick leave, and sickness absence during the year before baseline was obtained, as was information on all compensated days of sick leave, disability pension and death during follow-up.RESULTS:Slightly more than half the subjects were women, mean age was 39 years. Half of the study population returned to work within 14 days after baseline, and after three years only 15 subjects were still on sick leave. In multivariate proportional hazards regression analysis the extent of previous sick leave, age, being on part-time sick leave, and having a psychiatric, musculoskeletal, cardiovascular, nervous disease, digestive system, or injury or poisoning diagnosis decreased the return to work rate, while being employed increased it. Marital status, sex, being born in Sweden, citizenship, and annual salary had no influence. In logistic regression analyses across follow-up time these variables altogether explained 88-90% of return to work variation.CONCLUSIONS:Return to work was positively or negatively associated by a number of variables easily accessible in the GP's office. Track record data in the form of previous sick leave was the most influential variable.

Prevalence of atherosclerosis in individuals with prediabetes and diabetes compared to normoglycaemic individuals-a Swedish population-based study.
- 2023

Ingår i: Cardiovascular diabetology. - : BioMed Central (BMC). - 1475-2840. ; 22:1

Tidskriftsartikel (refereegranskat)abstract
- Patients with type 2 diabetes have an increased risk of death and cardiovascular events and people with diabetes or prediabetes have been found to have increased atherosclerotic burden in the coronary and carotid arteries. This study will estimate the cross-sectional prevalence of atherosclerosis in the coronary and carotid arteries in individuals with prediabetes and diabetes, compared with normoglycaemic individuals in a large population-based cohort.The 30,154 study participants, 50-64years, were categorized according to their fasting glycaemic status or self-reported data as normoglycaemic, prediabetes, and previously undetected or known diabetes. Prevalence of affected coronary artery segments, severity of stenosis and coronary artery calcium score (CACS) were determined by coronary computed tomography angiography. Total atherosclerotic burden was assessed in the 11 clinically most relevant segments using the Segment Involvement Score and as the presence of any coronary atherosclerosis. The presence of atherosclerotic plaque in the carotid arteries was determined by ultrasound examination.Study participants with prediabetes (n=4804, 16.0%) or diabetes (n=2282, 7.6%) had greater coronary artery plaque burden, more coronary stenosis and higher CACS than normoglycaemic participants (all, p<0.01). Among male participants with diabetes 35.3% had CACS≥100 compared to 16.1% among normoglycaemic participants. For women, the corresponding figures were 8.9% vs 6.1%. The prevalence of atherosclerosis in the coronary arteries was higher in participants with previously undetected diabetes than prediabetes, but lower than in patients with known diabetes. The prevalence of any plaque in the carotid arteries was higher in participants with prediabetes or diabetes than in normoglycaemic participants.In this large population-based cohort of currently asymptomatic people, the atherosclerotic burden in the coronary and carotid arteries increased with increasing degree of dysglycaemia. The finding that the atherosclerotic burden in the coronary arteries in the undetected diabetes category was midway between the prediabetes category and patients with known diabetes may have implications for screening strategies and tailored prevention interventions for people with dysglycaemia in the future.

STAT4 Associates with SLE through two independent effects that correlate with gene expression and act additively with IRF5 to increase risk
- 2009
-

- OBJECTIVES: To confirm and define the genetic association of STAT4 and systemic lupus erythematosus, investigate the possibility of correlations with differential splicing and/or expression levels, and genetic interaction with IRF5. METHODS: 30 tag SNPs were genotyped in an independent set of Spanish cases and controls. SNPs surviving correction for multiple tests were genotyped in 5 new sets of cases and controls for replication. STAT4 cDNA was analyzed by 5'-RACE PCR and sequencing. Expression levels were measured by quantitative PCR. RESULTS: In the fine-mapping, four SNPs were significant after correction for multiple testing, with rs3821236 and rs3024866 as the strongest signals, followed by the previously associated rs7574865, and by rs1467199. Association was replicated in all cohorts. After conditional regression analyses, two major independent signals represented by SNPs rs3821236 and rs7574865, remained significant across the sets. These SNPs belong to separate haplotype blocks. High levels of STAT4 expression correlated with SNPs rs3821236, rs3024866 (both in the same haplotype block) and rs7574865 but not with other SNPs. We also detected transcription of alternative tissue-specific exons 1, indicating presence of tissue-specific promoters of potential importance in the expression of STAT4. No interaction with associated SNPs of IRF5 was observed using regression analysis. CONCLUSIONS: These data confirm STAT4 as a susceptibility gene for SLE and suggest the presence of at least two functional variants affecting levels of STAT4. Our results also indicate that both genes STAT4 and IRF5 act additively to increase risk for SLE.

Referral of patients with cancer to palliative care: Attitudes, practices and work-related experiences among Swedish physicians
- 2022
-
Ingår i: European Journal of Cancer Care. - : Hindawi Limited. - 0961-5423 .- 1365-2354. ; 31:6
-
Tidskriftsartikel (refereegranskat)abstract
- Objective This study aimed to explore the attitudes, practices and work-related experiences among Swedish physicians regarding the referral process, integration and transition between oncology care and palliative care (PC). Methods A cross-sectional online survey was performed with a study-specific questionnaire in 2016-2017 in south-eastern Sweden. Physicians working with cancer patients within surgical specialties, medical specialties and paediatric oncology participated. Results The vast majority of the 130 participating physicians (99.2%) stated that PC was beneficial for the patient and were positive about early integration of PC (65.5%). Still, only 27.6% of the participants introduced PC at an early stage of non-curable disease. However, paediatric oncologists had a very early introduction of PC in comparison with medical specialties (p = 0.004). Almost 90% of the study population said they wanted to know that the patient had been taken care of by another care facility. Conclusions Despite the physicians' positive attitude towards early integration and referral to PC, they often acted late in the disease trajectory. This late approach can reduce the patient's opportunity of improving quality of life during severe circumstances. There is a need for in-depth knowledge of the physicians' challenges in order to bridge the gap between intentions and actions.

Estrogen and its receptors in adipose tissue from women and men : Associations with age, adiposity and type 2 diabetes
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Obesity and its complications, such as insulin resistance and type 2 diabetes (T2D), are leading causes of morbidity and mortality globally. Adipose tissue is important for whole-body homeostasis, functioning as an energy storage reservoir and an endocrine organ. Estrogens mediate their effects through estrogen receptor alpha (ESR1) and beta (ESR2) and contribute to sex and menopause-related differences in body fat distribution. Moreover, estrogens can be produced from androgens in the adipose tissue by the enzyme aromatase. The overall aim of this thesis was to investigate the role of estrogen and estrogen signalling in human adipose tissue and their association with age, adiposity, and insulin resistance. In Paper I, we assessed ESR1 and ESR2 gene expression in subcutaneous adipose tissue (SAT) from pre- and postmenopausal women, and investigated the effects of estradiol on adipocyte glucose uptake. We found that ESR2 gene expression was higher in postmenopausal women than premenopausal women. Moreover, in late, but not pre- or early postmenopausal women, estradiol incubation reduced basal and insulin-stimulated glucose uptake, which corresponded to an increase in ESR2 gene expression levels. The inhibiting effect of estradiol on adipocyte glucose uptake was prevented using an ESR2 antagonist. Subsequently, in Paper II we assessed the role of ESR2 in SAT lipid and glucose metabolism and preadipocyte differentiation. ESR2 expression in SAT was inversely correlated with markers of central adiposity and positively correlated with markers of lipid accumulation. Moreover, ESR2 knockdown impaired subcutaneous preadipocyte differentiation and glucose utilization. In Paper III, we focused on adipocyte lipolysis in women, which is regulated, in part, by catecholamines. OCT3, which mediates catecholamine transport into adipocytes, where they can be degraded, was increased in SAT with age, and higher in postmenopausal women than premenopausal women. Moreover, its expression was negatively associated with markers of insulin resistance and ex vivo lipolysis. Estradiol incubation of SAT downregulated OCT3 gene expression, which may explain lower OCT3 gene expression in premenopausal compared to postmenopausal women. In Paper IV, we focused on the role of aromatase and estradiol in SAT from men. We found that aromatase expression was higher in SAT from men with obesity and T2D compared to subjects without obesity and T2D, respectively, and was positively associated with markers of central obesity and markers of insulin resistance. Contrastingly, ESR1 expression in SAT was lower in men with obesity and T2D compared to subjects without obesity and T2D, respectively, and negatively associated with markers of obesity and insulin resistance. ESR2 expression was higher in SAT from men with T2D compared to men without T2D. Estradiol reduced insulin-stimulated glucose uptake, however, neither testosterone, nor aromatase inhibition, altered adipocyte glucose uptake. In this thesis, we found that estrogen has important metabolic effects in adipose tissue, including regulating lipid accumulation, glucose uptake capacity, and catecholamine transport. Overall, our findings suggest that estrogen and estrogen receptors may have an important role in age-, menopausal- and sex-dependent differences in body fat distribution, and may serve as potential targets for the prevention and treatment obesity and insulin resistance.

PLUS Borås : Om professionsutveckling och dokumentation
- 2009
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- PLUS betyder Projekt för Läsutveckling, Utvärdering och Samverkan. Det handlar om lässtimulerande arbete bland barn från nyfödd upp till 16 år och omfattar alltså alla barn- och skolbibliotekarier i Borås. Folkbiblioteken i Borås består av Stadsbiblioteket och nio kommundelsbibliotek. I kommundelarna är skol- och folkbiblioteken samorganiserade eller i nära samverkan. Samtliga högstadieskolor och flera låg- och mellanstadieskolor har fackutbildade bibliotekarier. Alla folkbiblioteksenheter har barnbibliotekarietjänster. Stadsbiblioteket ansvarar för att barnbibliotekarier och skolbibliotekarier träffas regelbundet i sina respektive nätverk. Läsfrämjande arbete bedrivs på alla bibliotek, drygt trettio personer arbetar med det på varsitt håll. Det finns mycket kunskap och gedigen erfarenhet men tid för reflektion och bollande med idéer för inspiration och metodikutveckling är mycket begränsad. Idéer till projektets innehåll baseras i strävan att knyta alla bibliotekarier som arbetar med språk- och läsutvecklingen till en gemensam bas och därmed skapa förutsättningar för ett utvecklingsarbete i hela kommunen.

Seasonal employees' intention to return and do more than expected
- 2012

Tidskriftsartikel (refereegranskat)abstract
- Seasonal employment is important in the service industries. Having motivated and satisfied employees is fundamental when front-line employees play a key role for the customers' perceived service quality. Seasonal work differs from permanent employment in many aspects and if managed properly, this could be a competitive advantage and contribute to the success of an organization. This study focuses on seasonal employees' intention to return and to do more than expected at work as well as the relationships between certain motivational factors and job satisfaction. A survey was carried out at four ski resorts with 477 respondents. Correlation and regression analyses indicate that job satisfaction influences the intention to return but does not have a strong influence on organizational citizenship behaviour (i.e. doing more than expected at work). The results improve our understanding of seasonal workers' motivation and behaviour. The concluding part discusses managerial implications.

Assessing short-term economic consequences of cow-calf contact systems in dairy production using a stochastic partial budgeting approach
- 2023
-
Ingår i: Frontiers in animal science. - 2673-6225. ; 4
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: While early separation of dairy calves after birth has been debated from an ethical and animal welfare lens, the economic evidence surrounding alternative cow-calf contact (CCC) systems is scarce.Methods: To address this knowledge gap, we assessed the economic consequences of CCC systems using data from the Agriwise database as well as parameters from published literature in a stochastic partial budget model. The implementation of CCC is very diverse between farms, so in our study we therefore selected a limited number of CCC systems to assess. The examined CCC systems were: (i) dam rearing with limited contact at milking (15 minutes twice a day for 115 days) with no manual milk feeding; (ii) dam rearing with 21-day full contact, after which calves are manually fed 8 kg of whole milk for 94 days; and (iii) mixed calf rearing with using both dams and foster cows with full contact; calves are initially kept with their dams and then moved to foster cows at 9 days of age.Results: We found that adoption of CCC systems was associated with decreases in contribution margins in the range of 1 to 5.4%, as compared to a rearing system where the calves were separated from their dams after one day and were manually fed 8 kg of milk for 12 weeks. These results illustrated that the costs associated with CCC systems may be fairly high under certain circumstances and may prohibit farmers from adopting this practice. Sensitivity analysis suggested that differences in milk sales, assumptions on changes in labor requirements, and changes in daily calf weight gain depending on CCC system were the main variables that governed the net impact on the contribution margins.Discussion: We did not include building costs in the analyses assuming that barn structures may not change in the short-term. The study focused only on short-term pecuniary associations between changes in CCC systems and contribution margins. To strengthen the economic decision-making around CCC systems, future research should consider non-monetary impacts of different CCC systems, as well as long-term economic impacts of these production strategies.

Informationsdesign i tillståndsövervakning : En studie av ett bildskärmsbaserat användargränssnitt för tillståndsövervakning och tillståndsbaserat underhåll
- 2010

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This research concerns the information design and visual design of graphical user interfaces (GUI) in the condition monitoring and condition-based maintenance (CBM) of production equipment. It also concerns various communicative aspects of a GUI, which is used to monitor the condition of assets. It applies to one Swedish vendor and its intentions to design information. In addition, it applies to the interaction between the GUI and its individual visual elements, as well as the communication between the GUI and the users (in four Swedish paper mills).The research is performed as a single case study. Interviews and observations have been the main methods for data collection. Empirical data is analyzed with methods inferred to semiotics, rhetoric and narratology. Theories in information science and regarding remediation are used to interpret the user interface design.The key conclusion is that there are no less than five different forms of information, all important when determining the conditions of assets. These information forms include the words, images and shapes in the GUI, the machine components and peripherals equipment, the information that takes form when personnel communicate machine conditions, the personnel’s subjective associations, and the information forms that relate to the personnel's actions and interactions.Preventive technicians interpret the GUI-information individually and collectively in relation to these information forms, which influence their interpretation and understanding of the GUI information. Social media in the GUI makes it possible to represent essential information that takes form when employees communicate a machine’s condition. Photographs may represent information forms as a machine’s components, peripherals, and local environment change over time. Moreover, preventative technicians may use diagrams and photographs in the GUI to change attitudes among the personnel at the mills and convince them, for example, of a machine’s condition or the effectiveness of CBM as maintenance policy.

Tidskriftsartikel (refereegranskat)abstract
- AimsHypertriglyceridaemia (hTG) is associated with atherosclerotic cardiovascular disease, pancreatitis, and non-alcoholic fatty liver disease (NAFLD) in large population-based studies. The understanding of the impact of hereditary hTG and cardiometabolic disease status on the development of hTG and its associated cardiometabolic outcomes is more limited. We aimed to establish a multigenerational cohort to enable studies of the relationship between hTG, cardiometabolic disease and hereditary factors.Methods and resultsThe population-based observational Stockholm hyperTRIglyceridaemia REGister (STRIREG) study includes 1 460 184 index individuals who have measured plasma triglycerides in the clinical routine in Region Stockholm, Sweden, between 1 January 2000 and 31 December 2021. The laboratory measurements also included basic haematology, blood lipid panel, liver function tests, and HbA1c. Using the Swedish Multi-Generation register, 2 147 635 parents and siblings to the indexes were identified to form the complete study cohort. Laboratory data from participants were combined with data from several national registers that provided information on the cause of death, medical diagnoses, dispensed medicines, and socioeconomic factors including country of birth, education level, and marital status.ConclusionThe multi-generational longitudinal STRIREG cohort provides a unique opportunity to investigate different aspects of hTG as well as heredity for other metabolic diseases. Important outcome measures include mortality, cardiovascular mortality, major cardiovascular events, development of incident diabetes, and NAFLD. The STRIREG study will provide a deeper understanding of the impact of hereditary factors and associated cardiometabolic complications.

- Introduction. Iatrogenic bile duct lesions following cholecystectomy represent a feared complication occurring in up to 0.9%. The aim of the present study was to estimate the total cost associated with both minor and major bile duct injuries. Material and methods. Detailed information on 24 consecutive patients, out of which 14 were considered to have minor and 10 patients considered as having major bile duct injury, provided the underlying information that rendered calculations on average individual costs for both groups of injuries. Results and discussion. Calculating individual costs for minor and major bile duct injuries with actual incidences of cholecystectomies performed and the incidence of iatrogenic bile duct injury demonstrated that the total costs, including in-hospital cost, sick leave and loss of production, were substantial. For the management of minor bile duct injuries costs were within the range of 136,787-159,585 EUR and for the management of major bile duct injuries from 336,903-449,204 EUR per million inhabitants and year. The total costs for the management of all types of bile duct injuries were thus within the range of 473,690-608,789 EUR per million inhabitants annually for the society.
