  • Increased mercury emissions from modern dental amalgams
  • 2017
  • Ingår i: Biometals. - : SPRINGER. - 0966-0844 .- 1572-8773. ; 30:2, s. 277-283

    • All types of dental amalgams contain mercury, which partly is emitted as mercury vapor. All types of dental amalgams corrode after being placed in the oral cavity. Modern high copper amalgams exhibit two new traits of increased instability. Firstly, when subjected to wear/polishing, droplets rich in mercury are formed on the surface, showing that mercury is not being strongly bonded to the base or alloy metals. Secondly, high copper amalgams emit substantially larger amounts of mercury vapor than the low copper amalgams used before the 1970s. High copper amalgams has been developed with focus on mechanical strength and corrosion resistance, but has been sub-optimized in other aspects, resulting in increased instability and higher emission of mercury vapor. This has not been presented to policy makers and scientists. Both low and high copper amalgams undergo a transformation process for several years after placement, resulting in a substantial reduction in mercury content, but there exist no limit for maximum allowed emission of mercury from dental amalgams. These modern high copper amalgams are nowadays totally dominating the European, US and other markets, resulting in significant emissions of mercury, not considered when judging their suitability for dental restoration.

  • Tågolyckan på Once station, Buenos Aires 2012
  • 2019
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Händelsen: Tågolyckan inträffade på morgonen den 22 februari 2012 när ett lokaltåg okontrollerat körde in i stoppanordningen i slutet av perrongen på Once station, i centrala Buenos Aires. Hastigheten var mellan 20 och 27 km i timmen, men stoppet var så kraftigt att vagn nummer två trängde sex meter in i vagn nummer ett. Sammanlagt skadades cirka 850 personer varav 51 avled, de flesta omkom i samband med att de två första vagnarna klämdes ihop. Bidragande faktorer till att så många skadades var, ett överfullt tåg av äldre modell, som var dåligt underhållet, och kördes av en organisation med låg säkerhetsmedvetenhet. Händelsen visar att en masskadesituation kan uppstå även vid låga hastigheter. Räddningsinsatsen var omfattande: ett hundratal ambulanser, tre helikoptrar och mer än 500 räddningsarbetare engagerades för att omhänderta skadade och fördela dem mellan huvudstadens 13 akutsjukhus. Beredskapen i Buenos Aires var god vid denna händelse, tack vare genomförda risk- och sårbarhetsanalyser, övningar och utbildningsinsatser. Den argentinska akutmedicinska responsorganisationen och sjukhusen arbetade i stor utsträckning enligt samma katastrofmedicinska principer som i Sverige. Händelsen kunde därför analyseras utifrån ett svenskt perspektiv.Erfarenheter: Sverige har varit relativt förskonat från tågolyckor med många svårt skadade. Däremot har tillbuden ökat kraftigt och järnvägssystemet är idag slitet och överbelastat. Det finns därför anledning att studera inträffade tågolyckor i världen för att dra lärdom av internationella erfarenheter av olika skadebegränsande faktorer som kan vara av betydelse för svensk katastrofmedicinsk beredskap. Det går att dra flera lärdomar ifrån tågolyckan på Once-stationen.Nedan redovisas ett antal sammanfattande slutsatser från händelsen med relevans för den svenska beredskapen:• Det finns en risk att händelser med många svårt skadade kan inträffa även vid låga hastigheter.• Tågens konstruktion, utformningen av koppel och deformationszoner, samt materielens förslitningsgrad är av stor betydelse för säkerheten.• Risken att passagerare, bagage och lösa föremål kastas runt i tågvagnen vid en häftig inbromsning är påtaglig.• Buffertstopp som är konstruerade så att de ger upphov till ett abrupt stopp, utgör en riskfaktor för allvarliga deformationsförlopp och skador, även vid låga hastigheter. TÅGOLYCKAN PÅ ONCE STATION, BUENOS AIRES 2012 SOCIALSTYRELSEN 9• Brister i företags och myndigheters kvalitetssäkring av sin verksamhet bidrar till att risken för händelser som tågolyckan på Once-stationen inträffar.• Varningar om tekniska fel som inte tas på allvar i organisationens säkerhetsarbete utgör en riskfaktor.• Bristande träning bland räddningspersonal i de räddningstekniska svårigheter som kan uppstå vid en tågolycka, till exempel att ta loss fastklämda, kan bidra till att hantering av drabbade fördröjs.• Förmågan att bedöma situationen och prioritera bland de drabbade i samråd med medicinskt ansvarig kan sannolikt vara av stor betydelse för att minska insatstiden till de svårast klämda och skadade.• Samtliga sjukhus bör ha en i förväg fastställd förmåga att ta emot patienter vid förstärknings- respektive katastrofläge, så att särskild sjukvårdsledning på regional nivå har möjlighet att snabbt fördela ett stort antal skadade.• En väl fungerande plan för krisstöd och samlad anhörigupplysning underlättar för den somatiska vården. Brister i en sådan plan får stora konsekvenser för allmänhetens förtroende.• För att hantera en lika stor tågolycka i Sverige kan flera regioner behöva engageras, vilket ställer stora krav på ledningsförmågan i den drabbade regionen. Dessutom behövs en effektiv samverkan mellan lokal, regional och nationell nivå. Det är därför nödvändigt med en gemensam nationell ledningsmodell vid särskild händelse, gemensamma kris- och katastrofmedicinska utbildningar och regelbundna övningar.

  • Pharmacological targeting of MTHFD2 suppresses acute myeloid leukemia by inducing thymidine depletion and replication stress
  • 2022
  • Ingår i: NATURE CANCER. - : Springer Science and Business Media LLC. - 2662-1347. ; 3:2, s. 156-
  • Tidskriftsartikel (refereegranskat)abstract
    • The folate metabolism enzyme MTHFD2 (methylenetetrahydrofolate dehydrogenase/cyclohydrolase) is consistently overexpressed in cancer but its roles are not fully characterized, and current candidate inhibitors have limited potency for clinical development. In the present study, we demonstrate a role for MTHFD2 in DNA replication and genomic stability in cancer cells, and perform a drug screen to identify potent and selective nanomolar MTHFD2 inhibitors; protein cocrystal structures demonstrated binding to the active site of MTHFD2 and target engagement. MTHFD2 inhibitors reduced replication fork speed and induced replication stress followed by S-phase arrest and apoptosis of acute myeloid leukemia cells in vitro and in vivo, with a therapeutic window spanning four orders of magnitude compared with nontumorigenic cells. Mechanistically, MTHFD2 inhibitors prevented thymidine production leading to misincorporation of uracil into DNA and replication stress. Overall, these results demonstrate a functional link between MTHFD2-dependent cancer metabolism and replication stress that can be exploited therapeutically with this new class of inhibitors. Helleday and colleagues describe a nanomolar MTHFD2 inhibitor that causes replication stress and DNA damage accumulation in cancer cells via thymidine depletion, demonstrating a potential therapeutic strategy in AML tumors in vivo.

  • Polymorphisms in alpha - and betaadrenergic receptor genes, hypertension and obstructive sleep apnea. The Skaraborg Sleep Study. J Hypertension
  • 2010
  • Ingår i: International Journal of Hypertension. - 2090-0392. ; 2010:Art ID 458410
  • Tidskriftsartikel (refereegranskat)abstract
    • The sympathetic nervous system and the adrenergic receptors play an important role in regulation of blood pressure. This study explored the associations between functional polymorphisms of the α(2B)-, β(1)-, and β(2)-adrenergic receptor genes and obstructive sleep apnea (OSA) in hypertensive patients and hypertension in patients with OSA in a populationbased sample of 157 hypertensive patients and 181 healthy control subjects. Only the Arg389Gly polymorphism of the β(1)-adrenergic receptor gene was associated with increased risk for mild OSA in hypertensive patients (Arg/Arg versus Gly/Arg/Gly/Gly, 2.1, 95% CI, 1.02-4.7). Hypertensive men carrying the Arg389Arg genotype had higher crude and age-adjusted AHI than carriers of the Arg389Gly/Gly389Gly genotypes. When adjusted also for BMI this difference became borderline significant. This difference was not observed in women. The risk of hypertension in mild OSA was associated with increasing number of Arg-alleles (Arg/Arg OR 5.4, 95% CI 1.4-21.2).

  • Visualization of β-carotene and starch granules in plant cells using CARS and SHG microscopy
  • 2010
  • Ingår i: Journal of Raman Spectroscopy. - : Wiley. - 0377-0486 .- 1097-4555. ; 42:4, s. 586-592
  • Tidskriftsartikel (refereegranskat)abstract
    • Information on the content and bioavailability of provitamin A carotenoids, such as beta-carotene, in plant foods is of great interest due to the widespread vitamin A deficiency in developing countries. While the amount of beta-carotene can readily be quantified with analytical techniques, there is limited information on beta-carotene morphology in native plant materials. Here, we introduce nonlinear microscopy for three-dimensional, label-free imaging of carotenoids in fresh and thermally treated plant tissues, providing quantitative information at single-aggregate level and detailed insight into their distribution. Carotenoids in orange-fleshed sweet potato (OFSP), carrot, and mango were visualized by coherent anti-Stokes Raman scattering (CARS) microscopy and, in the case of OFSP, related to the plant-matrix morphology by simultaneous second-harmonic generation (SHG) microscopy of starch granules. Sizes, shapes, densities, and location of different types of carotenoid bodies were quantified. While OFSP and carrot showed heterogeneous rod-shaped bodies with high carotenoid densities indicated by higher CARS signals, the carotenoid-filled lipid droplets in mango appeared as homogeneous low-density aggregates of rounded shape. In addition, beta-carotene densities and morphologies in OFSP were studied after thermal processing, showing that the bodies remain intact despite significant changes of the surrounding starch granules.

  • Predictors of acute myocardial infarction mortality in hypertensive patients treated in primary care.
  • 2007
  • Ingår i: Scandinavian Journal of Primary Health Care. - : Informa UK Limited. - 0281-3432 .- 1502-7724. ; 25:4, s. 237-243
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To explore risk factors for acute myocardial infarction (AMI) mortality in hypertensive patients treated in primary care. Design. Community-based cohort study. Setting. Hypertension outpatient clinic in primary health care. Subjects. Patients who consecutively underwent an annual follow-up during 1992-1993 (n =894; 377 men and 517 women). Methods. All events of fatal AMI were ascertained by record linkage to the National Mortality Register to December 31, 2002. Gender-specific predictors for AMI mortality were analysed by Cox regression. Main outcome measure. AMI mortality. Results. During a mean follow-up of 8.7 years 32 cases (8.5%) of fatal AMI were observed in men and 31 cases (6.0%) were observed in women. Most important predictors for AMI mortality in men were microalbuminuria (HR 3.8, CI 1.8-8.0) and left ventricular hypertrophy (HR 4.0, CI 1.7-9.4), whilst in women type 2 diabetes (HR 4.8, CI 2.4-9.8) was an important predictor. In hypertensive patients without diabetes male gender was associated with high AMI mortality (HR 2.7, CI 1.4-5.3), but in patients with both hypertension and type 2 diabetes the higher risk in men disappeared (HR 0.8, CI 0.4-1.7). Conclusion. Cardiovascular disease risk factors remain strong predictors of AMI mortality in hypertensive patients but with a different pattern in the two genders. Markers of organ damage are more important predictors in men, whereas markers of impaired glucose metabolism are more important predictors in women.

  • Risk factor clustering in patients with hypertension and non-insulin-dependent diabetes mellitus. The Skaraborg Hypertension Project
  • 1998
  • Ingår i: Journal of Internal Medicine. - 1365-2796. ; 243:3, s. 223-232
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To assess the coexistence of hypertension and diabetes, associations with cardiovascular risk factors and the achievement of current treatment goals. DESIGN: A community-based, cross-sectional, observational study. SETTING: Hypertension and diabetes outpatient clinics in primary health care, Skara, Sweden. SUBJECTS: All patients (n = 1116; 488 men, 628 women) who performed an annual follow-up from May 1992 to September 1993. MAIN OUTCOME MEASURES: Hypertension, non-insulin-dependent diabetes mellitus (NIDDM), blood pressure, fasting B-glucose, lipids, HbAlc, body mass index (BMI), waist hip ratio (WHR). RESULTS: Hypertension alone was found in 286 men and 430 women, hypertension and NIDDM combined in 102 men and 102 women, and NIDDM alone in 100 men and 96 women. Taking new cases into account, the proportion of hypertension among NIDDM patients was 57%, and the proportion of NIDDM among hypertensives was 26%. Men and women with both hypertension and NIDDM had a higher systolic blood pressure and women also had a higher diastolic blood pressure (men 168/88 mmHg, women 165/86 mmHg) than those with hypertension alone (men 152/87 mmHg, women 156/82 mmHg) (P < or = 0.001). Cardiovascular risk factors accumulated in patients with both hypertension and NIDDM (triglycerides, BMI and WHR). A diastolic blood pressure < or = 90 mmHg was achieved by 71% men and 84% women with hypertension. HbAlc < 7.5% was attained by 71% men and 70% women with NIDDM. CONCLUSIONS: A considerable coexistence of hypertension and NIDDM was demonstrated. Cardiovascular risk factors clustered in patients with both diseases and their blood pressure was less controlled. These patients thus comprised a clinically defined group at high risk. By current guidelines, control of hypertension and NIDDM seemed appropriate.

  • Self-Reported Food-Related Gastrointestinal Symptoms in IBS Are Common and Associated With More Severe Symptoms and Reduced Quality of Life
  • 2013
  • Ingår i: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270. ; 108:5, s. 634-641
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: Despite the fact that food and diet are central issues, that concern patients with irritable bowel syndrome (IBS), the current understanding about the association between the intake of certain foods/food groups and the gastrointestinal (GI) symptom pattern, psychological symptoms, and quality of life is poor. The aim of this study was to determine which food groups and specific food items IBS patients report causing GI symptoms, and to investigate the association with GI and psychological symptoms and quality of life. METHODS: We included 197 IBS patients (mean age 35 (18–72) years; 142 female subjects) who completed a food questionnaire in which they specified symptoms from 56 different food items or food groups relevant to food intolerance/allergy. The patients also completed questionnaires to assess depression and general anxiety (Hospital Anxiety and Depression), GI-specific anxiety (Visceral Sensitivity Index), IBS symptoms (IBS-Severity Scoring System), somatic symptoms (Patient Health Questionnaire-15), and quality of life (Irritable Bowel Syndrome Quality of Life Questionnaire). RESULTS: In all, 84% of the studied population reported symptoms related to at least one of the food items surveyed. Symptoms related to intake of food items with incompletely absorbed carbohydrates were noted in 138 (70%) patients; the most common were dairy products (49%), beans/lentils (36%), apple (28%), flour (24%), and plum (23%). Of these, 58% experienced GI symptoms from foods rich in biogenic amines, such as wine/beer (31%), salami (22%), and cheese (20%). Histamine-releasing foods, such as milk (43%), wine/beer (31%), and pork (21%), were also considered causes of symptoms in IBS patients. GI symptoms were also frequently reported after intake of fried and fatty foods (52%). With increasing IBS symptom severity, patients reported more food items responsible for their GI symptoms (P=0.004), and this was also found in patients with more severe somatic symptoms (P<0.0001). Women tended to report more food items causing symptoms than men (P=0.06). A high number of food items causing GI symptoms was also associated with reduced quality of life and this was significant for the following domains: sleep (r=−0.25; P=0.001), energy (r=−0.21; P=0.005), food (r=−0.29; P<0.001), social functioning (r=−0.23; P=0.001), and physical status (r=−0.16; P<0.05). However, the number of food items reported to provoke GI symptoms was unrelated to body mass index, age, IBS subtype, anxiety, depression, or GI-specific anxiety. CONCLUSIONS: The majority of IBS patients believe that certain food items are important triggers of their GI symptoms. This is especially true for foods containing carbohydrates and fat, and also may be relevant for histamine-releasing food items and foods rich in biogenic amines. Self-reported food intolerance is associated with high symptom burden and reduced quality of life.

  • Incident gout and risk of first-time acute coronary syndrome: a prospective, population-based, cohort study in Sweden
  • 2023
  • Ingår i: Arthritis Care and Research. - : Wiley. - 2151-464X .- 2151-4658. ; 75:6, s. 1292-1299
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To investigate the risk of first-time acute coronary syndrome (ACS) in a large cohort of primary and secondary care patients with incident gout, compared to the general population. Methods: Using register data for the period 2007 ̶ 2017, we conducted a prospective, population-based cohort with 20,146 patients with incident gout (mean age, 65.6 years; 67.4% males) and 83,517 matched population controls, without prior history of coronary heart disease. We calculated incidence rates (IR) and hazard ratios (HR) adjusted for baseline comorbidities and dispensed prescriptions. In a sensitivity analysis, we included gout cases and controls with no previously diagnosed comorbidity (6,075 cases and 44,091 controls). Results: The IR of first-time ACS was significantly increased in the gout cohort, compared to controls (9.1 vs 6.3/1,000 person-years). Unadjusted cox regression showed that gout patients had higher risk of first-time ACS compared to controls (HR, 1.44; 95%CI, 1.33-1.56), with higher HR in women (HR, 1.64; 95%CI, 1.41 ̶ 1.90) than in men (HR, 1.36; 95%CI, 1.24 ̶ 1.50). In multivariable analysis the risk diminished but remained significant (HR, 1.15; 95%CI, 1.06-1.25). The risk was similar in the sensitivity analysis (HR, 1.20; 95%CI, 1.01-1.44), and still higher in women (HR, 1.34; 95%CI, 0.86-2.08), than in men (HR, 1.18; 95%CI, 0.97-1.44). Conclusion: Patients with incident gout have a 44% increased risk of first-time ACS, higher in women than in men. This risk is largely explained by the underlying comorbidities, but there is still a modestly increased risk that may be due to gout-related factors.

    • The purpose of this study was to determine and describe the ideas, that is, a mental construction of perceived reality and values, which are expressed in the Swedish Disability Act and its Government Bill. By means of text analysis, four concepts of reality and values have been identified: (1) Citizenship and justice, (2) The collective and integration, (3) The individual and autonomy, and (4) Decentralization and power shifts. The study also shows that social rights and social citizenship have been strengthened via legislation for individuals with comprehensive disabilities. It is also demonstrated that there is considerable room in the legislation for conflicts between the two concepts and values of collective/integration and the individual/autonomy. It can also be observed that there is a considerable risk that citizens are not treated in a similar manner as regards the interpretation and application of the Disability Act, which may lead to lack of legal security.

  • Modification of IgE binding during heat processing of the cow's milk allergen beta-lactoglobulin
  • 2004
  • Ingår i: J Agric Food Chem. ; 52:5
  • Tidskriftsartikel (refereegranskat)abstract
    • The effect of heat treatment on the IgE binding ability of beta-lactoglobulin, as pure protein or in whole milk, was studied by inhibition of IgE antibody binding using FEIA-CAP inhibition. A slight but significant decreased IgE binding was seen between unheated and heat-treated beta-lactoglobulin solution at 74 degrees C (IC(50) = 2.03 and 3.59 microg/mL, respectively, p = 0.032). A more pronounced decrease was found at 90 degrees C with an IC(50) of 8.45 microg/mL (p = 0.014). The inhibition of IgE binding of milk after heat treatment at 90 degrees C was also significantly decreased (p = 0.007). However, at all heat treatments, a similar total amount of IgE antibodies could be inhibited at a sufficiently high concentration of beta-lactoglobulin. The inhibiting ability of beta-lactoglobulin was significantly impaired in some fermented acidified milk products such as yogurt as compared to that in nonfermented milk (p < 0.001). There was only a small difference of IgE binding between the native forms of genetic variants A and B.

  • Modification of IgE Binding to beta-Lactoglobulin by Fermentation and Proteolysis of Cow's Milk
  • 2005
  • Ingår i: J Agric Food Chem. ; 53:9
  • Tidskriftsartikel (refereegranskat)abstract
    • The effect of fermentation by Lactobacilli and of proteolytic hydrolysis of whole milk on the IgE binding ability of beta-lactoglobulin was studied using an ELISA inhibition assay. Sera from nine adult milk allergic patients were tested. The individual sera showed a similar inhibition pattern in the changes during fermentation and proteolysis. The degradation of beta-lactoglobulin was studied with liquid chromatography. In general, fermentation with Lactobacilli gave little effect on IgE binding, even though chromatography data showed a gradual degradation of beta-lactoglobulin. Proteolysis with trypsin, however, gave extensive degradation of beta-lactoglobulin and strongly decreased IgE binding. In addition, we measured the inhibition pattern of beta-lactoglobulin in various selected commercially available fermented milk products. These showed an IgE binding capacity similar to that of nonfermented high pasteurized milk.

  • Use of serum or buffer-changed EDTA-plasma in a rapid, inexpensive, and easy-to-perform hemolytic complement assay for differential diagnosis of systemic lupus erythematosus and monitoring of patients with the disease
  • 2007
  • Ingår i: Clinical and Vaccine Immunology. - 1556-6811 .- 1556-679X. ; 14:5, s. 549-555
  • Tidskriftsartikel (refereegranskat)abstract
    • We previously described a simplified quantitative hemolytic assay for classical pathway (CP) hemolytic function in serum that has been shown to correlate with the 50% hemolytic complement (CH50) assay. In the present study, we used this assay to compare CP functions; plasma levels of C3, C4, and C3dg; and ratios of C3dg to C3 in healthy individuals and patients with systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA) with different degrees of complement activation. A significant depression in CP function and levels of C4 and C3 and increased C3dg levels and C3dg/C3 ratios were observed in the SLE patients. In patients with RA, CP function was normal, whereas C3, C4, and C3dg levels and the C3dg/C3 ratio were elevated. The SLE results are compatible with systemic complement consumption, whereas the RA data suggest an acute-phase reaction with a normal C3 catabolic rate. To facilitate the handling of patient samples, we also developed a method to restore the hemolytic function of EDTA-plasma by transferring it to Veronal-buffered saline containing the thrombin inhibitor lepirudin. This process inhibits coagulation and enables complement activation, allowing a longer time lag between sample harvesting and testing. These results, combined with previous correlation studies, suggest that the CP hemolytic assay can effectively replace the CH50 assay for routine SLE differential diagnosis and monitoring of disease activity.

  • Housing support workers as equilibrists between instrumentality and situation : a qualitative study in congregated housings for people with smi
  • 2014
  • Ingår i: Vulnerable Groups & Inclusion. - 2000-8023 .- 2000-8023. ; 5
  • Tidskriftsartikel (refereegranskat)abstract
    • Community-based psychiatry as an arena for studying work efforts is relatively unexplored. The professional role of a housing support worker (HSW) in congregated supported housings for people with severe mental illness (SMI) is fairly new. The role has emerged due to major changes in Swedish mental care and services. Our aim was to describe the work experiences of HSWs and to understand the conditions provided when work assignments are being constructed. By doing this we provide an important piece of the puzzle in understanding the processes in contemporary congregated supported housings for people with SMI. Four focus group interviews were conducted and included 25 participants. Four different facilities of congregated supported housings for people with SMI were represented in the material. The interpretation of the material was inspired by a constructionist approach. The work of an HSW is experienced as complex and ambiguous. Together with different significant actors (including objects), the HSWs are negotiating the content of the responsibilities. Thus, different actors help co-construct the work content. Furthermore, the HSWs are caught between two different logics, one that is related to a complex practice and one that is related to instrumental and routine-based ideas. The complex emotional work of an HSW is often not supported by the principles of the organization. The findings can be helpful when organizing the work in congregated supported housings for people with SMI. This paper highlights the importance of bridging the gap between organizational demands and expectations and the individual preconditions and basic needs.

Together with different significant actors (including objects), the HSWs are negotiating the content of the responsibilities. Thus, different actors help co-construct the work content. Furthermore, the HSWs are caught between two different logics, one that is related to a complex practice and one that is related to instrumental and routine-based ideas. The complex emotional work of an HSW is often not supported by the principles of the organization. The findings can be helpful when organizing the work in congregated supported housings for people with SMI. This paper highlights the importance of bridging the gap between organizational demands and expectations and the individual preconditions and basic needs.

    • BACKGROUND: Work and employees are often marginalized in studies on community-based psychiatric care and support systems. This paper highlights the role of the worker at congregated supported housing for people with severe mental illness (SMI). Housing support workers (HSW) are a fairly new professional role and have developed as a result of major changes in Swedish mental health care and services. The development of new roles is not unproblematic and raises intriguing questions.OBJECTIVE: The purpose of this article is to describe housing support workers’ experiences of meaning in their work, and in addition illuminate how the work identity of HSWs can be negotiated and constructed.METHODS: Four focus group interviews were conducted with a total of 25 participants. Additionally, three follow up sessions were conducted with the same participants. The material consists of employees from four different sites. The intepretation of the material was inspired by a constructionist approach.RESULTS: The analysis generated three themes: to do a good job, everyday needs and the formal role. The work identity for HSWs is complex and not easily interpreted.CONCLUSIONS: The experience of an unclear assignment affects the description of what is meaningful and important—the work identity and significant affiliations for HSWs. In the long run, this fragmented world can have negative implications for the HSW.

  • Structure-brain exposure relationships in rat and human using a novel data set of unbound drug concentrations in brain interstitial and cerebrospinal fluids
  • 2009
  • Ingår i: Journal of Medicinal Chemistry. - : American Chemical Society (ACS). - 0022-2623 .- 1520-4804. ; 52:20, s. 6233-6243
  • Tidskriftsartikel (refereegranskat)abstract
    • New experimental methodologies were applied to measure the unbound brain-to-plasma concentration ratio (K(p,uu,brain)) and the unbound CSF-to-plasma concentration ratio (K(p,uu,CSF)) in rats for 43 structurally diverse drugs. The relationship between chemical structure and K(p,uu,brain) was dominated by hydrogen bonding. Contrary to popular understanding based on the total brain-to-plasma concentration ratio (logBB), lipophilicity was not a determinant of unbound brain exposure. Although changing the number of hydrogen bond acceptors is a useful design strategy for optimizing K(p,uu,brain), future improvement of in silico prediction models is dependent on the accommodation of active drug transport. The structure-brain exposure relationships found in the rat also hold for humans, since the rank order of the drugs was similar for human and rat K(p,uu,CSF). This cross-species comparison was supported by K(p,uu,CSF) being within 3-fold of K(p,uu,brain) in the rat for 33 of 39 drugs. It was, however, also observed that K(p,uu,CSF) overpredicts K(p,uu,brain) for highly effluxed drugs, indicating lower efflux capacity of the blood-cerebrospinal fluid barrier compared to the blood-brain barrier.

  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Subjective symptoms after food challenges are difficult to interpret and no standard is available. We discuss a strategy for how to interpret a diary. Furthermore, the interobserver reliability is evaluated. METHODS: Diaries for 32 patients with subjective symptoms were used. The diaries were re-evaluated with a predefined strategy by three independent observers. RESULTS: The proportion of positives was 21.9% among the old diagnoses, according to the new approach 34.4% (observers I and II) and 37.5% (observer III) were positive. The new approach had high interobserver reliability (97 and 100%). CONCLUSIONS: The proportion of positives depends on how subjective symptoms are interpreted. Interpretations of subjective symptoms in diaries could be made with high interobserver reliability.

  • Phases in development of an interactive mobile phone-based system to support self-management of hypertension
  • 2014

  • Tidskriftsartikel (refereegranskat)abstract
    • Hypertension is a significant risk factor for heart disease and stroke worldwide. Effective treatment regimens exist; however, treatment adherence rates are poor (30%–50%). Improving self-management may be a way to increase adherence to treatment. The purpose of this paper is to describe the phases in the development and preliminary evaluation of an interactive mobile phone-based system aimed at supporting patients in self-managing their hypertension. A person-centered and participatory framework emphasizing patient involvement was used. An interdisciplinary group of researchers, patients with hypertension, and health care professionals who were specialized in hypertension care designed and developed a set of questions and motivational messages for use in an interactive mobile phone-based system. Guided by the US Food and Drug Administration framework for the development of patient-reported outcome measures, the development and evaluation process comprised three major development phases (1, defining; 2, adjusting; 3, confirming the conceptual framework and delivery system) and two evaluation and refinement phases (4, collecting, analyzing, interpreting data; 5, evaluating the self-management system in clinical practice). Evaluation of new mobile health systems in a structured manner is important to understand how various factors affect the development process from both a technical and human perspective. Forthcoming analyses will evaluate the effectiveness and utility of the mobile phone-based system in supporting the self-management of hypertension.

  • Tidskriftsartikel (refereegranskat)abstract
    • Obstructive sleep apnoea (OSA) is a recognised risk factor for hypertension (HT). The current authors investigated confounders of this association in a sex-balanced community-based sample of patients with HT (n=161) from the Skaraborg Hypertension and Diabetes Project (n=1,149) and normotensive controls (n=183) from an age and sex stratified community-based population sample (n=1,109). All participants underwent ambulatory home polysomnography. Severe OSA (apnoea-plus-hypopnoea index (AHI) >= 30 events center dot h(-1)) was found in 47 and 25% of hypertensive and normotensive males, respectively. The corresponding numbers in females were 26 and 24%, respectively. The odds ratio (OR) for HT increased across AHI tertiles from 1.0 to 2.1 (95% confidence interval: 0.9-4.5) and 1.0 to 3.7 (95% CI: 1.7-8.2) in males, but not in females where the OR increased from 1.0 to 1.8 (95% CI: 0.8-3.9) and 1.0 to 1.6 (95% CI: 0.7-3.5). Regression analysis correcting for age, body mass index (or waist-hip ratio) and smoking did not eliminate the association between OSA and HT in males. The present data suggest that obstructive sleep apnoea is highly prevalent in both the general population and in patients with known hypertension. The contribution of obstructive sleep apnoea to hypertension risk may be sex dependent and higher in males than in females.

    • Silicon surfaces have been cleaned and bonded in ultra-high vacuum at a pressure in the 10-10 torr range. The bonded interfaces show extremely low contamination levels as measured by secondary ion mass spectroscopy. Nevertheless, a potential barrier could be detected at the interface spreading resistance and current vs. temperature measurements. This suggests that the barrier is caused by inevitable dislocation networks due to wafer misorientation, as well as residual oxygen at the interface

  • Understanding adherence to therapeutic guidelines: a multilevel analysis of statin prescription in the Skaraborg Primary Care Database
  • 2011
  • Ingår i: European Journal of Clinical Pharmacology. - : Springer Science and Business Media LLC. - 1432-1041 .- 0031-6970. ; 67:4, s. 415-423
  • Tidskriftsartikel (refereegranskat)abstract
    • In Skaraborg, Sweden, the economic responsibility for tax-financed prescription drug costs was transferred from the regional administrative level to the local level (health care centre; HCC) in 2003. The aim of this study was to investigate the impact of this decentralization of economic responsibility on adherence to guidelines for prescribing lipid-lowering drugs. Data from all 24 public HCCs in Skaraborg on prescriptions for lipid-lowering drugs during 2003 and 2005 were extracted from the Skaraborg Primary Care Database (SPCD). Multilevel regression analysis (MLRA) was used to disentangle the variances at different levels of data (patient, physician, HCC). The outcome variable on the patient level was the prescription of the recommended statin (yes/no). Sex and age of the patients and sex, age and occupational status of the physician were included as fixed effects. The variance was expressed as the median odds ratio (MOR). The prevalence of adherence to guidelines for the prescription of statins increased from 77% in 2003 to 84% in 2005. The MLRA showed that in 2003 the variance was equally distributed between the HCC and physician levels (MORHCC2003 = 1.89 vs. MORPHYSICIAN2003 = 1.88). The variance between physicians and between HCCs decreased considerably between 2003 and 2005. The inclusion of individual and physician characteristics did not explain any of the remaining variance. The decentralized budget appears to have increased adherence to guidelines and reduced inefficient variation in prescribing.

  • Validity of registration of ICD codes and prescriptions in a research database in Swedish primary care: a cross-sectional study in Skaraborg primary care database
  • 2010
  • Ingår i: BMC Medical Informatics and Decision Making. - : Springer Science and Business Media LLC. - 1472-6947. ; 10
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: In recent years, several primary care databases recording information from computerized medical records have been established and used for quality assessment of medical care and research. However, to be useful for research purposes, the data generated routinely from every day practice require registration of high quality. In this study we aimed to investigate (i) the frequency and validity of ICD code and drug prescription registration in the new Skaraborg primary care database (SPCD) and (ii) to investigate the sources of variation in this registration. Methods: SPCD contains anonymous electronic medical records (ProfDoc III) automatically retrieved from all 24 public health care centres (HCC) in Skaraborg, Sweden. The frequencies of ICD code registration for the selected diagnoses diabetes mellitus, hypertension and chronic cardiovascular disease and the relevant drug prescriptions in the time period between May 2002 and October 2003 were analysed. The validity of data registration in the SPCD was assessed in a random sample of 50 medical records from each HCC (n = 1200 records) using the medical record text as gold standard. The variance of ICD code registration was studied with multi-level logistic regression analysis and expressed as median odds ratio (MOR). Results: For diabetes mellitus and hypertension ICD codes were registered in 80-90% of cases, while for congestive heart failure and ischemic heart disease ICD codes were registered more seldom (60-70%). Drug prescription registration was overall high (88%). A correlation between the frequency of ICD coded visits and the sensitivity of the ICD code registration was found for hypertension and congestive heart failure but not for diabetes or ischemic heart disease. The frequency of ICD code registration varied from 42 to 90% between HCCs, and the greatest variation was found at the physician level (MORPHYSICIAN = 4.2 and MORHCC = 2.3). Conclusions: Since the frequency of ICD code registration varies between different diagnoses, each diagnosis must be separately validated. Improved frequency and quality of ICD code registration might be achieved by interventions directed towards the physicians where the greatest amount of variation was found.

  • Variations in dental anxiety among middle-aged and elderly women in Sweden: a longitudinal study between 1968 and 1996.
  • 1999
  • Ingår i: Journal of dental research. - : SAGE Publications. - 0022-0345 .- 1544-0591. ; 78:10, s. 1655-61
  • Tidskriftsartikel (refereegranskat)abstract
    • Cross-sectional studies have shown that older individuals are significantly less dentally anxious than younger ones. However, research has not been able to show if this is a cohort effect or an effect of fear declining with age. If it is a cohort effect, dental anxiety among the elderly may pose a greater-than-expected problem for the providers of dental services. With the exception of longitudinal studies in children and a three-year follow-up on adults, no truly longitudinal epidemiological studies concerning dental anxiety have been performed. The aim of this project was to investigate how dental anxiety changes with aging. In a longitudinal population study of women in Göteborg, Sweden, starting in 1968, 1462 women aged 38 to 54 participated. A representative subsample of 778 women took part in a psychiatric examination where an investigation of dental anxiety was included. The same questions were also included when these women were re-examined in 1974, 1992, and 1996. Three hundred seventy-five women were still eligible for investigation in 1996. In 1968-69, 48 (12.8%) of the participating women assessed themselves as "very afraid" or "terrified" when visiting the dentist, and in 1996 the frequency was 21 (5.6%) among the same women. In 1968-69, 180 women (48%) reported no dental anxiety when visiting the dentist, and 28 years later the frequency was 230 (61%). In the three youngest age groups, dental anxiety decreased significantly (p < 0.001) over the 28-year period. Older compared with younger women reported significantly less dental anxiety, and this was an age effect rather than a cohort effect. Thus, this longitudinal study supported the hypothesis that dental fear, like many other general and specific phobias, declines with age.

    • In literature, many authors have pointed to the importance of technology and technology development for company competitiveness. In this study we aim to study the technology in more detail and attempt to develop an understanding on the requirements and needs on “technology” from the perspective of product development. The research question which we aim to answer in this study is:“What are the requirements on maturity of technology when this technology is about to enter into the product development process?“A qualitative research strategy, based on three study cases involving 17 interviewees, has been chosen. All three cases come from one single company, Volvo Aero Corporation (VAC) in Sweden, in the context of the aero engine industry. The study contributes with a broad mapping of requirements and how they relate to different categories of technologies, showing big differences both regarding content and timing. It is concluded that attention should be payed both to how the organization builds new capabilities and to the capabilities of the technology itself. A surprisingly complicated picture on the requirements relating to the implementation of new technologies has emerged in the study. This contributes to the understanding regarding the difficulties of developing new technology and integrating it into an application.

    • Background: No strawberry allergen has so far been identified and characterized. Methods: Serum samples were collected from patients with a suggestive case history of adverse reactions to strawberry and other fruits. Extracts from fresh and frozen strawberries were analysed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), Western blotting and mass spectrometry. Patient blood samples were analysed for inhibition of IgE binding and basophil degranulation. Results: Several IgE-binding proteins could be detected. In more than half of the patient sera, a 20/18-kDa doublet band was observed in Western blotting. These two bands were excised and analysed by mass spectrometry showing the presence of proteins belonging to the Bet v 1 family of allergens. Inhibition of the IgE binding to the 20/18-kDa doublet was obtained by addition of two recombinantly expressed allergens belonging to the Bet v 1 family (Bet v 1 and Mal d 1) and strawberry protein extract. In a cell-based assay of patient blood samples, basophil degranulation could be induced by strawberry protein extract and by Bet v 1 and Mal d 1. Conclusions: We conclude that strawberry homologues to Bet v 1 may be allergens of importance for adverse reactions to strawberry.

  • Tidskriftsartikel (refereegranskat)abstract
    • Previous studies of donor or recipient origin of posttransplant lymphoproliferative disorders (PTLDs) following solid organ transplantation (SOT) have either been small or with selected patient groups. We studied tumor origin in a population-based cohort of 93 patients with PTLD following SOT. Tumor origin of PTLD tissue was analyzed by fluorescence in situ hybridization of the sex chromosomes in cases of sex mismatch between donor and recipient (n=41), or HLA genotyping in cases of identical sex but different HLA type (n=52). Tumor origin of PTLD could be determined in 67 of the 93 cases. All 67 PTLDs were of recipient origin. They were found in recipients of kidney (n=38), liver (n=12), heart (n=10) and lung (n=7). The most common recipient-derived lymphomas were monomorphic B-cell PTLDs (n=45), monomorphic T cell PTLDs (n=9), indolent lymphomas (n=6), and polymorphic PTLD (n=4). Half of the recipient-derived PTLDs were Epstein–Barr virus-positive. Twelve of the recipient-derived PTLDs were located in the grafts: in four cases exclusively and in eight cases in combination with disseminated disease outside the graft. Tumor origin was indeterminable in 26 cases, probably due to low DNA quality. We conclude that the vast majority of PTLDs after SOT was of recipient origin.

    • Department of Medicine II, University of Göteborg, Sahlgren's Hospital, Sweden. OBJECTIVE--To assess the relationship between family history and different types of obesity and change in obesity in a longitudinal population study. RESEARCH DESIGN AND METHODS--A longitudinal population study of 1462 randomly selected women (38-60 yr old) was conducted in Göteborg, Sweden, in 1968-69. The women were restudied after 12 yr. RESULTS--A family history of diabetes in mothers but not fathers showed, in univariate analysis, a significant positive association with obesity expressed as BMI. A family history of diabetes in the mothers was inversely related to body fat distribution expressed as WHR. No other association was observed between family history of diabetes and WHR. The association with BMI was independent of age, WHR, smoking habits, blood glucose, systolic blood pressure, serum cholesterol, serum triglycerides, maternal obesity, and the incidence of diabetes during the 12-yr follow-up period. Twelve years later, in 1980-1981, an independent association still existed between family history for diabetes and BMI measured at that examination, whereas there was no relationship with WHR. Women who had a family history of diabetes increased their BMI significantly more during the 12-yr follow-up compared with the women without a family history of diabetes, whereas there was no difference for the change of WHR. Family history of coronary heart disease and family history of cancer did not correlate to any kind of obesity. CONCLUSIONS--These findings indicate that family history of diabetes is related to overall obesity but not to abdominal adiposity per se. PMID: 1468270 [PubMed - indexed for MEDLINE]

  • Local allergic reaction in food-hypersensitive adults despite a lack of systemic food-specific IgE
  • 2002
  • Ingår i: J Allergy Clin Immunol. ; 109:5 Pt 1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Objective tools are lacking for the diagnosis of local gastrointestinal inflammatory reactions in skin prick test (SPT)-negative and serum IgE antibody (s-IgE Ab)-negative patients with suspected food allergy. OBJECTIVE: The purpose of this investigation was to evaluate the presence of eosinophils, T cells, local IgE-bearing cells, IL-4, and IFN-gamma in small intestinal biopsy specimens from adult SPT-negative/s-IgE Ab-negative patients with food allergy during symptomatic and nonsymptomatic periods. METHODS: Fourteen patients with food allergy-related gastrointestinal symptoms confirmed by double-blinded, placebo-controlled food challenge (DBPCFC) were investigated. Eleven of the patients were SPT-negative and s-IgE Ab-negative. Sex- and age-matched healthy volunteers were used as controls. Duodenal biopsies were studied with immunostaining through use of a panel of mouse monoclonal antibodies specific for eosinophils, CD3, CD4, CD8, IgE, IL-4, and IFN-gamma. RESULTS: Significant increases in numbers of MBP(+) eosinophils, IgE-bearing cells, and T cells were found in the duodenal mucosa of the patients when they were symptomatic in comparison with when they were asymptomatic and in comparison with healthy controls. Numbers of IL-4(+) cells were increased and numbers of IFN-gamma(+) cells were reduced in the patients when they were symptomatic in comparison with when they were asymptomatic and in comparison with the controls. There were no differences in total s-IgE levels between any of the groups. CONCLUSION: A significant correlation was found between the appearance of symptoms of food hypersensitivity and the duodenal presence of IgE-bearing cells, activated eosinophils, and T cells in patients with negative SPT results and negative s-IgE Ab to the offending food. We suggest that a localized IgE-mediated response caused the gastrointestinal symptoms seen in these patients.

    • Background The effect of interleukin 17-inhibitors on anterior uveitis (AU) in spondyloarthritis (SpA) is poorly understood. This study aimed to compare the risk of AU during treatment with secukinumab versus tumour necrosis factor inhibitors (TNFi). Methods Patients with SpA starting secukinumab or a TNFi 2015 through 2018 were identified in the Swedish Rheumatology Quality Register. Occurrence of AU was identified based on diagnosis codes in outpatient ophthalmology care in the National Patient Register. The main outcomes were crude rates of AU-diagnoses per 100 patient-years, and adjusted HRs for AU, during treatment, in patients without AU during the year before treatment start (in order to reduce confounding by indication). HRs were adjusted for age, sex, history of AU and patient global assessment of disease activity. Results Based on 4851 treatment starts (456 secukinumab; 4395 any TNFi), the rate of AU-diagnoses per 100 patient-years was 6.8 (95% CI 5.2 to 8.7) for secukinumab. Among the TNFi, the rate varied from 2.9 (95% CI 2.1 to 3.7) for infliximab and 4.0 (95% CI 3.3 to 4.9) for adalimumab to 7.5 (95% CI 6.7 to 8.4) for etanercept. The adjusted HRs for first AU (adalimumab as reference) were: secukinumab 2.32 (95% CI 1.16 to 4.63), infliximab 0.99 (95% CI 0.49 to 1.96), etanercept 1.82 (95% CI 1.13 to 2.93), golimumab 1.59 (95% CI 0.90 to 2.80) and certolizumab 1.12 (95% CI 0.44 to 2.83). Sensitivity analyses confirmed the pattern of higher AU rates with secukinumab and etanercept versus monoclonal TNFi. Conclusion As used in clinical practice in SpA, secukinumab appears to be associated with a higher risk of AU, compared with the monoclonal TNFi and a similar risk compared with etanercept.
