  • The Simons Observatory : science goals and forecasts
  • 2019
  • Ingår i: Journal of Cosmology and Astroparticle Physics. - : IOP Publishing. - 1475-7516. ; :2
  • Tidskriftsartikel (refereegranskat)abstract
    • The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scientific goals of the experiment, motivate the design, and forecast its performance. SO will measure the temperature and polarization anisotropy of the cosmic microwave background in six frequency bands centered at: 27, 39, 93, 145, 225 and 280 GHz. The initial con figuration of SO will have three small-aperture 0.5-m telescopes and one large-aperture 6-m telescope, with a total of 60,000 cryogenic bolometers. Our key science goals are to characterize the primordial perturbations, measure the number of relativistic species and the mass of neutrinos, test for deviations from a cosmological constant, improve our understanding of galaxy evolution, and constrain the duration of reionization. The small aperture telescopes will target the largest angular scales observable from Chile, mapping approximate to 10% of the sky to a white noise level of 2 mu K-arcmin in combined 93 and 145 GHz bands, to measure the primordial tensor-to-scalar ratio, r, at a target level of sigma(r) = 0.003. The large aperture telescope will map approximate to 40% of the sky at arcminute angular resolution to an expected white noise level of 6 mu K-arcmin in combined 93 and 145 GHz bands, overlapping with the majority of the Large Synoptic Survey Telescope sky region and partially with the Dark Energy Spectroscopic Instrument. With up to an order of magnitude lower polarization noise than maps from the Planck satellite, the high-resolution sky maps will constrain cosmological parameters derived from the damping tail, gravitational lensing of the microwave background, the primordial bispectrum, and the thermal and kinematic Sunyaev-Zel'dovich effects, and will aid in delensing the large-angle polarization signal to measure the tensor-to-scalar ratio. The survey will also provide a legacy catalog of 16,000 galaxy clusters and more than 20,000 extragalactic sources.

  • Mobility, muscular strength and endurance in the cervical spine in Swedish air force pilots
  • 2001
  • Ingår i: Aviation, Space and Environmental Medicine. - 0095-6562 .- 1943-4448. ; 72:4, s. 336-342
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Muscle strength, endurance and range of movement of the cervical spine in a group of Swedish Air Force jet pilots (AF) and in a reference group of conscripts doing their military service (RG) were compared. METHODS: We tested 30 (AF) 24-42 yr and 33 (RG) 19-22 yr. A questionnaire was used to document complaints. Maximum voluntary isometric muscle strength of the flexor and extensor muscles of the cervical spine and sub-maximum isometric endurance in the flexor and extensor muscles were measured. RESULTS: Eleven AF (37%) and four RG (12%) had experienced discomfort in the neck within the previous year. The pilots' flexor and extensor muscle strength (47 Nm and 65 Nm) was superior to that of the conscripts (36 Nm and 59 Nm) (p = 0.0001, p = < 0.05, respectively). However, the RG group had greater isometric endurance in the flexor muscles than AF (p = < 0.05) and greater neck rotation (p = <0.005). There was no difference between the two groups in the other variables. CONCLUSION: Differences between the groups with regard to muscle strength and endurance might depend on variations in work-related physical muscle strain, and/or differences in fiber composition in the muscles, which might be reflected by pilot selection procedures.

  • 2016
  • Rapport (populärvet., debatt m.m.)abstract
    • Rapporten redovisar arbeten från kursen Restaureringskonst på Konsthögskolan som under läsåret 2015-2016 har arbetat med tema Museum och Iscensättning. Hur kulturmiljöer påverkas när de blir museum, hur man restaurerar för museum, hur man bevarar och utvecklar en plats för kunskapsutbyte, bildning och upplevelser. Mälsåkers slott, utanför Mariefred, förvaltat av Statens Fastighetsverk, var studieobjekt för 20 studenter, (yrkesverksamma arkitekter, antikvarier, ingenjörer, konservatorer m fl) där utbildningens olika studiemoment som uppmätning, inventering, dokumentation har tillämpats. Fältarbetet har följts av studier i historik, kulturhistorisk värdering och analyser som gett visioner och gestaltningsförslag på ny verksamhet i slottet. Rapporten presenterar förslagen, med text, skisser, foton och ritningar. Fyra olika typer av museum med varierande grad av åtgärder, förändringar och utveckling av slottet. Restaureringsexperiment redovisas utifrån traditionella och digitala dokumentationsmetoder. Dessutom finns arbeten om barockens ljus, bladguld, brandskydd, pod-radio, kraftstation, engelska parken, dekorationsmålade tak, Gustavianum, Julius Kronbergs ateljé och barockträdgård m m. Förslagen visar att det är möjligt att transformera Mälsåkers barockslott till ett museum av idag med bibehållen historik och synliga tidslager.

  • Adult height is associated with risk of cancer and mortality in 5.5 million Swedish women and men
  • 2019
  • Ingår i: Journal of Epidemiology and Community Health. - : BMJ. - 0143-005X .- 1470-2738. ; 73:8, s. 730-736
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Previous studies have indicated that taller individuals are at greater risk of developing cancer. Death from cancer and other specific causes have also been linked to height, but the results have been inconclusive. We aimed to shed further light on the associations between height, cancer incidence and mortality.Methods We conducted a nationwide, population-based prospective cohort study, including 5.5 million Swedish women and men (aged 20-74). They were followed over a period of up to 54 years. Heights were retrieved from national registers (mainly the Passport Register where heights are most often self-reported). The risks of overall and specific cancers, as well as overall and cause-specific mortality, were presented as HR with 95% CIs per 10 cm increase in height.Results A total of 278 299 cases of cancer and 139 393 cases of death were identified. For overall cancer, HR was 1.19 (1.18-1.20) in women and 1.11 (1.10-1.12) in men for every 10 cm increase in height. All 15 specific cancer types were positively associated with height-most strongly for malignant melanoma in both genders, with HRs of 1.39 (1.35-1.43) in women and 1.34 (1.30-1.38) in men. For overall mortality, HR was 0.98 (0.97-0.99) in women and 0.91 (0.90-0.92) in men for every 10 cm increase in height. Cancer mortality was increased in taller individuals, with HR 1.15 (1.13-1.17) in women and 1.05 (1.03-1.07) in men for every 10 cm increase in height, whereas shorter individuals had increased overall mortality due to a number of other causes, such as cardiovascular disease.Conclusion Overall and specific cancer risks, particularly malignant melanoma, were positively associated with height. Cancer mortality also increased with height. In contrast, overall mortality was decreased with height, particularly in men due to inverse associations with height for other causes of death.

  • Deep brain stimulation in the caudal zona incerta versus best medical treatment in patients with Parkinson's disease : a randomised blinded evaluation
  • 2018
  • Ingår i: Journal of Neurology, Neurosurgery and Psychiatry. - : BMJ Publishing Group Ltd. - 0022-3050 .- 1468-330X. ; 89:7, s. 710-716
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Several open-label studies have shown good effect of deep brain stimulation (DBS) in the caudal zona incerta (cZi) on tremor, including parkinsonian tremor, and in some cases also a benefit on akinesia and axial symptoms. The aim of this study was to evaluate objectively the effect of cZi DBS in patients with Parkinson's disease (PD).Method: 25 patients with PD were randomised to either cZi DBS or best medical treatment. The primary outcomes were differences between the groups in the motor scores of the Unified Parkinson's Disease Rating Scale (UPDRS-III) rated single-blindly at 6 months and differences in the Parkinson's Disease Questionnaire 39 items (PDQ-39). 19 patients, 10 in the medical arm and 9 in the DBS arm, fulfilled the study.Results: The DBS group had 41% better UPDRS-III scores off-medication on-stimulation compared with baseline, whereas the scores of the non-surgical patients off-medication were unchanged. In the on-medication condition, there were no differences between the groups, neither at baseline nor at 6 months. Subitems of the UPDRS-III showed a robust effect of cZi DBS on tremor. The PDQ-39 domains 'stigma' and 'ADL' improved only in the DBS group. The PDQ-39 summary index improved in both groups.Conclusion: This is the first randomised blinded evaluation of cZi DBS showing its efficacy on PD symptoms. The most striking effect was on tremor; however, the doses of dopaminergic medications could not be decreased. cZi DBS in PD may be an addition to existing established targets, enabling tailoring the surgery to the needs of the individual patient.

  • The association between exposure to clozapine, olanzapine, and quetiapine and the outcomes perimyocarditis and heart failure : A population-based cohort study
  • 2023
  • Ingår i: Psychiatry Research. - : Elsevier. - 0165-1781 .- 1872-7123. ; 326
  • Tidskriftsartikel (refereegranskat)abstract
    • The risk of cardiac adverse events following clozapine use is debated and is unknown for the chemically related and widely used antipsychotics olanzapine and quetiapine. National Swedish registers were used to identify all patients 16-75 years old with antipsychotic dispensations between 2005 and 2018. The short-term outcome was a diagnosis of perimyocarditis (pericarditis and/or myocarditis) within two months of first dispensation, and the long-term outcome was heart failure (including cardiomyopathy) within three years. Cox regressions with time varying exposure were used to estimate hazard rates (HR) and their 95% confidence intervals (CI). A total of 201,045 individuals were included in the cohort. The risk of developing perimyocarditis during clozapine treatment tripled compared to no antipsychotic treatment (HR 3.4, CI 1.6-7.3), although the absolute rate remained comparably low. The long-term risk of heart failure during clozapine treatment was also elevated (HR 1.3, CI 1.1-1.7). Treatment with either or both olanzapine or quetiapine was not associated with an increased relative risk of perimyocarditis, or heart failure compared to no antipsychotic treatment. Clozapine use is therefore associated with a substantially elevated short-term risk of perimyocarditis and an increased risk of heart failure within three years.

  • Cancer risk in patients with primary immune thrombocytopenia - A Swedish nationwide register study
  • 2020
  • Ingår i: Cancer Epidemiology. - : ELSEVIER SCI LTD. - 1877-7821 .- 1877-783X. ; 69
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Immune thrombocytopenia (ITP) is an autoimmune disease treated with immunosuppressive agents, thrombopoietin receptor agonists, immunomodulation drugs and/or splenectomy. Patients with ITP have been found to have increased risk ofhematological malignancies. Studies investigating stomach/liver cancer are contradictory and the risk of developing other solid tumors is largely unknown. We aimed at estimating risk of overall and organ-specific cancers in patients with primary ITP.Methods: The study population was Swedish patients with at least one ITP diagnosis recorded in the National Patient Register and a 1:10 matched comparison cohort from the population. The study period covers 1997-2016. The Cancer Register and the Cause of Death Register provided data on malignancies and deaths, respectively. Primary ITP was identified using an established algorithm. We used time-split Cox models to estimate hazard ratios (HRs) with 95 % confidence intervals (CIs), adjusted for age, sex, index-year, county, income, education, Charlson score and number of inand outpatient contacts.Results: In total 66,134 individuals were included in the study. Patients with ITP had higher risk of gastrointestinal, skin (all morphologies), lymphoid and hematological cancers. Adjusted HR (95 % CI) for cancer was 1.37 (1.27-1.48), with highest risk during the first year, but with increased risk remaining for up to 20 years for men. For women, the overall risk was increased during the first year, HR (95 % CI) 2.00 (1.55-2.60). A significantly increased liver cancer risk was seen up to 9 years after diagnosis.Conclusion: Patients with primary ITP have higher risk of cancer than the population. The observed increased risk does not seem to be solely due to surveillance bias, but might be associated with ITP or its treatments. Treating hematologists need to have high index of suspicion for cancer.

  • Patient characteristics when starting treatment and patterns of treatment in adults with chronic immune thrombocytopenia
  • 2019
  • Ingår i: Blood Coagulation and Fibrinolysis. - : LIPPINCOTT WILLIAMS & WILKINS. - 0957-5235 .- 1473-5733. ; 30:7, s. 350-356

    • Asymptomatic patients with primary chronic immune thrombocytopenia (ITP) are not recommended treatment if their platelet counts are above 30 x 10(9)/l. Factors such as age and comorbidities may influence clinical manifestations and should be considered for treatment decisions. The aim of this study was to determine the impact of clinical characteristics for initiation of ITP treatment, and the patterns of ITP treatment given. We performed an observational cohort study in Sweden with information from medical records and National Health Registers. Adults diagnosed with incident primary ITP between years 2009 and 2016 were included. Multinomial logistic regression was used to assess the impact of factors predicting treatment start. Out of 858 patients with chronic ITP from 71 hospitals we identified 585 (68%) with a first ITP treatment. For 537 (92%) corticosteroids were the first choice. The median platelet counts at start of treatment was 12 x 10(9)/l (interquartile range 5-27 x 10(9)/l). The variables predicting treatment start were platelet counts below 20 x 10(9)/l and treatment with antihypertensive drugs. Patients with diabetes were less likely to receive corticosteroids. Severe bleeding occurred in 75 (13%) of the patients. Platelet counts below 20 x 10(9)/l, antihypertensive treatment and bleedings were the strongest predictors of treatment start, diabetes yielded lower odds to start corticosteroid treatment. The majority of the patients had corticosteroids as first treatment while second treatment was diverse. Asymptomatic thrombocytopenia is not considered a reason as such for initiating treatment. In the latter years, splenectomy seemed to occur later in the course of treatment.

  • Estrogen-modulating treatment among mid-life women and COVID-19 morbidity and mortality : a multiregister nationwide matched cohort study in Sweden
  • 2024
  • Ingår i: BMC Medicine. - : BioMed Central (BMC). - 1741-7015. ; 22:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundIt has been repeatedly shown that men infected by SARS-CoV-2 face a twofold higher likelihood of dying, being hospitalized or admitted to the intensive care unit compared to women, despite taking into account relevant confounders. It has been hypothesized that these discrepancies are related to sex steroid hormone differences with estrogens being negatively correlated with disease severity. The objective of this study was therefore to evaluate COVID-19-related mortality and morbidity among peri- and postmenopausal women in relation to estrogen-containing menopause hormonal treatments (MHT).MethodsThis is a national register-based matched cohort study performed in Sweden between January 1 to December 31, 2020. Study participants comprised women over the age of 53 years residing in Sweden. Exposure was defined as prescriptions of local estrogens, systemic estrogens with and without progestogens, progestogens alone, or tibolone. MHT users were then compared with a matched cohort of non-users. The primary outcome consisted of COVID-19 mortality, whereas the secondary outcomes included inpatient hospitalizations/outpatient visits and confirmed SARS-CoV-2 infection. Multivariable adjusted Cox regression-derived hazard ratios (HRs) were calculated.ResultsUse of systemic estrogens alone is associated with increased COVID-19 mortality among older women (aHR 4.73, 1.22 to 18.32), but the association is no longer significant when discontinuation of estrogen use is accounted for. An increased risk for COVID-19 infection is further observed for women using combined systemic estrogens and progestogens (aHR 1.06, 1.00 to 1.13) or tibolone (aHR 1.21, 1.01 to 1.45). Use of local estrogens is associated with an increased risk for COVID-19-related death (aHR 2.02,1.45 to 2.81) as well as for all secondary outcomes.ConclusionsSystemic or local use of estrogens does not decrease COVID-19 morbidity and mortality to premenopausal background levels. Excess risk for COVID-19 morbidity and mortality was noted among older women and those discontinuing systemic estrogens. Higher risk for death was also noted among women using local estrogens, for which non-causal mechanisms such as confounding by comorbidity or frailty seem to be the most plausible underlying explanations.

  • Effect of pamidronate 30 mg versus 90 mg on physical function in patients with newly diagnosed multiple myeloma (Nordic Myeloma Study Group): a double-blind, randomised controlled trial
  • 2010
  • Ingår i: LANCET ONCOLOGY. - : Elsevier Science B.V., Amsterdam.. - 1470-2045 .- 1474-5488. ; 11:10, s. 973-982

    • Background Compared with placebo, prophylactic treatment with bisphosphonates reduces risk of skeletal events in patients with multiple myeloma. However, because of toxicity associated with long-term bisphosphonate treatment, establishing the lowest effective dose is important. This study compared the effect of two doses of pamidronate on health-related quality of life and skeletal morbidity in patients with newly diagnosed multiple myeloma. Methods This double-blind, randomised, phase 3 trial was undertaken at 37 clinics in Denmark, Norway, and Sweden. Patients with multiple myeloma who were starting antimyeloma treatment were randomly assigned in a 1:1 ratio to receive one of two doses of pamidronate (30 mg or 90 mg) given by intravenous infusion once a month for at least 3 years. Randomisation was done by use of a central, computerised minimisation system. Primary outcome was physical function after 12 months estimated by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire (scale 0-100). All patients who returned questionnaires at 12 months and were still on study treatment were included in the analysis of the primary endpoint. This study is registered with ClinicalTrials. gov, number NCT00376883. Findings From January, 2001, until August, 2005, 504 patients were randomly assigned to pamidronate 30 mg or 90 mg (252 in each group). 157 patients in the 90 mg group and 156 in the 30 mg group were included in the primary analysis. Mean physical function at 12 months was 66 points (95% CI 62.9-70.0) in the 90 mg group and 68 points (64.6-71.4) in the 30 mg group (95% CI of difference -6.6 to 3.3; p=0.52). Median time to first skeletal-related event in patients who had such an event was 9.2 months (8.1-10.7) in the 90 mg group and 10-2 months (7.3-14.0) in the 30 mg group (p=0.63). In a retrospective analysis, eight patients in the pamidronate 90 mg group developed osteonecrosis of the jaw compared with two patients in the 30 mg group. Interpretation Monthly infusion of pamidronate 30 mg should be the recommended dose for prevention of bone disease in patients with multiple myeloma.

  • Quality of Life of an Adolescent Boy with Autism and Intellectual Impairment, a unique housing situation.
  • 2006
  • Ingår i: International Journal of Disability, Community and Rehabilitation. - 1703-3381. ; 5:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract in UndeterminedIndividuals with the diagnosis of autism need well-functioning home environment to make progress and achieve an acceptable level of quality of life (QoL). Long-term mapping of the daily life of individual persons with disabilities with the purpose of understanding their living situation is rare. The present study deals with the QoL of an adolescent boy with autism and intellectual impairment and living in an apartment of his own together with four caregivers, during a period of three and a half years. This single case study reports the qualitative analysis of the caregivers' open diary and repeated interviews capturing the boy's daily life and explores the staff's experiences of the boy's living situation. The results describe how important aspects for the QoL such as communication, activities, mood and regulation, were influenced by the boy's home care environment. The staff paid most attention to the boy's mood and meal-related situations and seemed to be unaware of the importance of improving communication. Findings in the diary and the interviews indicate that the boy seemed to regress in important skills and abilities despite the efforts of the staff.

  • 2008
  • Ingår i: Scandinavian Journal of Disability Research. - : Stockholm University Press. - 1501-7419 .- 1745-3011. ; 10:1, s. 49-66
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this single-case study was to describe the staff's collaborative work process for a period of 3.5 years caring for an adolescent boy with autism and intellectual disabilities living in an apartment of his own together with his caregivers. The longitudinal data included the staff's (two men and two women) common open diary, repeated individual interviews and focus group interviews. Detailed content analysis of the diary and the interviews indicated that the staff's perceptions of their pedagogical work, teamwork and work conditions changed from a positive to a largely negative view, appearing to affect the pedagogical strategies adopted. Also, it became visible that the unique work situation, involving a lack of actual goals, feedback and pedagogical supervision may have negatively affected the collaborative work process and the staff's effort to establish structure and consensus in the pedagogical work.

  • Ingår i: Surgical Endoscopy. - : Springer Science and Business Media LLC. - 0930-2794 .- 1432-2218. ; 34, s. 1939-1947
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Perforations related to endoscopic retrograde cholangiopancreatography (ERCP) are rare but feared adverse events with highly reported morbidity and mortality rates. The aim was to evaluate the incidence and outcome of ERCP-related perforations and to identify risk factors for death due to perforations in a population-based study.Methods: Between May 2005 and December 2013, a total of 52,140 ERCPs were registered in GallRiks, a Swedish nationwide, population-based registry. A total of 376 (0.72%) were registered as perforations or extravasation of contrast during ERCP or as perforation in the 30-day follow-up. The patients with perforation were divided into fatal and non-fatal groups and analyzed for mortality risk factors. The case volume of centers and endoscopists were divided into the upper quartile (Q4) and the lower three quartile (Q1-3) groups. Furthermore, fatal group patients' records were reviewed.Results: Death within 90 days after ERCP-related perforations or at the index hospitalization occurred in 20% (75 out of 376) for all perforations and 0.1% (75 out of 52,140) for all ERCPs. The independent risk factors for death after perforation were malignancy (OR 11.2, 95% CI 5.8-21.6), age over 80 years (OR 3.8, 95% CI 2.0-7.4), and sphincterotomy in the pancreatic duct (OR 2.8, 95% CI 1.1-7.5). In Q4 centers, the mortality was similar with or without pancreatic duct sphincterotomy (14% vs. 13%, p = 1.0), but in Q1-3 centers mortality was higher (45% vs. 21%, p = 0.024).Conclusions: ERCP-related perforations are severe adverse events with low incidence (0.7%) and high mortality rate up to 20%. Malignancy, age over 80 years, and sphincterotomy in the pancreatic duct increase the risk to die after a perforation. The risk of a fatal outcome in perforations after pancreatic duct sphincterotomy was reduced when occurred at a Q4-center. In the case of a complicated perforation a transfer to a Q4-center may be considered.

  • Intensive therapy for multiple myeloma in patients younger than 60 years. Long-term results focusing on the effect of the degree of response on survival and relapse pattern after transplantation
  • 2006
  • Ingår i: Haematologica. - 0390-6078 .- 1592-8721. ; 91:9, s. 1228-1233
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and Objectives. From 1994 to 1997 we conducted a population-based, prospective study on intensive therapy in newly diagnosed symptomatic myeloma patients younger than 60 years, comparing their survival to that of a conventionally treated historic population. Long-term results are presented, including the impact of the degree of response on survival and relapse pattern after transplantation. Design and Methods. The prospective population was formed of 397 patients and the historic population of 313 patients. Both populations were calculated to comprise more than 75% of the expected number of new cases. Results. After a median follow-up of 7 years survival was longer in the prospective population than in the historic one (median 60 versus 39 months; p=0.0002). When comparing only patients eligible for intensive therapy the median survival was 63 versus 44 months (p < 0.0001). Attaining a complete response was associated with prolonged event-free survival but not overall survival. The pattern of relapse after transplantation was heterogeneous but could be divided into four major groups; insidious, classical, plasmacytoma form and transformed disease. The median survival after relapse was 29 months. The relapse pattern and time to relapse predicted outcome. Patients relapsing with an insidious or classical form of disease with skeletal events only, or after a long lasting first response were likely to respond well to conventional salvage therapy. In contrast, relapse with multiple symptoms, transformed disease or a short duration of first response implied bad prognosis. Interpretation and conclusions. The relapse pattern after autologous transplantation is heterogeneous and response to salvage therapy is variable. The degree of response and event-free survival after transplantation are not reliable surrogate markers for survival.

  • An algorithm for rule-in and rule-out of acute myocardial infarction using a novel troponin I assay
  • 2017
  • Ingår i: Heart. - : BMJ. - 1355-6037 .- 1468-201X. ; 103:2, s. 125-131
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective To derive and validate a hybrid algorithm for rule-out and rule-in of acute myocardial infarction based on measurements at presentation and after 2 hours with a novel cardiac troponin I (cTnI) assay. Methods The algorithm was derived and validated in two cohorts (605 and 592 patients) from multicentre studies enrolling chest pain patients presenting to the emergency department (ED) with onset of last episode within 12 hours. The index diagnosis and cardiovascular events up to 30 days were adjudicated by independent reviewers. Results In the validation cohort, 32.6% of the patients were ruled out on ED presentation, 6.1% were ruled in and 61.3% remained undetermined. A further 22% could be ruled out and 9.8% ruled in, after 2 hours. In total, 54.6% of the patients were ruled out with a negative predictive value (NPV) of 99.4% (95% CI 97.8% to 99.9%) and a sensitivity of 97.7% (95% CI 91.9% to 99.7%); 15.8% were ruled in with a positive predictive value (PPV) of 74.5% (95% CI 64.8% to 82.2%) and a specificity of 95.2% (95% CI 93.0% to 96.9%); and 29.6% remained undetermined after 2 hours. No patient in the rule-out group died during the 30-day follow-up in the two cohorts. Conclusions This novel two-step algorithm based on cTnI measurements enabled just over a third of the patients with acute chest pain to be ruled in or ruled out already at presentation and an additional third after 2 hours. This strategy maximises the speed of rule-out and rule-in while maintaining a high NPV and PPV, respectively.

  • Heparin-binding protein: A diagnostic marker of acute bacterial meningitis
  • 2011
  • Ingår i: Critical Care Medicine. - 0090-3493. ; 39:4, s. 812-817
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The early detection of bacterial meningitis is crucial for successful outcome. Heparin-binding protein, a potent inducer of increased vascular permeability, is released from activated neutrophils in severe sepsis. OBJECTIVE: In this study we investigated whether heparin-binding protein levels in cerebrospinal fluid could be used as a diagnostic marker for acute bacterial meningitis. DESIGN: One prospective and one retrospective patient cohort from two university hospitals in Sweden were analyzed. SETTING AND PATIENTS: Cerebrospinal fluid samples were collected from 174 patients with suspected central nervous system infection. Thirty-seven patients with acute community-acquired bacterial meningitis, four patients with neurosurgical bacterial meningitis, 29 patients with viral meningitis or encephalitis, seven patients with neuroborreliosis, and 97 control patients were included. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Cerebrospinal fluid samples were analyzed for the concentrations of heparin-binding protein, lactate, protein, glucose, neutrophils, and mononuclear cells. Heparin-binding protein levels were significantly higher (p < .01) in patients with acute bacterial meningitis (median 376 ng/mL, range 12-858 ng/mL) than in patients with viral central nervous system infection (median 4.7 ng/mL, range 3.0-41 ng/mL) or neuroborreliosis (median 3.6 ng/mL, range 3.2-10 ng/mL) or in control patients with a normal cerebrospinal fluid cell count (median 3.5 ng/mL, range 2.4-8.7 ng/mL). In the prospectively studied group, a heparin-binding protein concentration exceeding 20 ng/mL gave a sensitivity of 100%, a specificity of 99.2%, and positive and negative predictive values of 96.2% and 100%, respectively, in diagnosing acute bacterial meningitis. The area under the receiver-operating characteristic curve for heparin-binding protein was 0.994, which was higher than for the other investigated parameters. CONCLUSION: Elevated cerebrospinal fluid levels of heparin-binding protein distinguish between patients with acute bacterial meningitis and patients with other central nervous system infections.

  • Knowledge support for environmental information on pharmaceuticals : experiences among Swedish Drug and Therapeutics Committees
  • 2023
  • Ingår i: BMC Health Services Research. - : BioMed Central (BMC). - 1472-6963. ; 23:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundTwo publicly available Swedish knowledge support systems, “Pharmaceuticals and Environment” on Janusinfo.se and Fass.se, provide environmental information on pharmaceuticals. Janusinfo is provided by the public healthcare system in Stockholm and Fass is provided by the pharmaceutical industry. The objectives of this study were to investigate the experiences among Swedish Drug and Therapeutics Committees (DTCs) with using the databases, retrieve development proposals for these, and investigate the DTCs’ challenges with working with pharmaceuticals in the environment.MethodsA cross-sectional survey with 21 questions, both closed and open-ended, was distributed electronically in March 2022 to Sweden’s 21 DTCs. Descriptive statistics and inductive categorization were used for the analysis.ResultsA total of 132 respondents from 18 regions filled out the survey. The average regional response rate was 42%. The DTCs used the knowledge supports to consider environmental aspects of pharmaceuticals in their formularies and in education. Respondents were more familiar with Janusinfo compared to Fass but appreciated the availability of both. The DTCs especially valued the concrete proposals for certain active pharmaceutical ingredients on Janusinfo. Respondents requested that all medicinal products have environmental information on Fass. Challenges included lack of data, lack of transparency from the pharmaceutical industry and difficulties considering the environmental aspect of pharmaceuticals in their healthcare practice. Respondents wanted more knowledge, clear messages, and legislation to support their work to reduce the negative environmental impact of pharmaceuticals.ConclusionsThis study demonstrates that knowledge supports for environmental information on pharmaceuticals are valuable for the DTCs in Sweden, but the respondents experienced challenges in their work in this field. The study can provide insights to those in other countries interested in considering environmental aspects in their formulary decision-making.

  • Bilinear Regression and Second Order Calibration
  • 1999
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • We consider calibration of second-order (or "hyphenated") instruments for chemical analysis. Many such instruments generate bilinear two-way (matrix) type data for each specimen. The bilinear regression model is to be estimated from a number of specimens of known composition. Once we have established the regression model from the calibration with specimens of known composition, we can use the model to predict the composition of a new specimen. For the estimation part we propose a new, simple estimator, which we call the SVD (singular value decomposition) estimator, and illustrate how it works on real and simulated data, as compared with other estimation methods, in particular bilinear least squares (BLLS). The SVD estimator is usually only slightly less efficient than BLLS, because it is based on reweighted least squares normal equations. In particular the statistical precision of the SVD estimator and that of BLLS are theoretically investigated, and the methods are compared and illustrated on real and simulated data. The advantages of our method over bilinear least squares are that it is faster and easier to compute, its standard errors are more easily and explicitly obtained, and it has a simpler correlation structure. We also develop a prediction theory based on any of these two estimators. There are numerous alternative estimation/prediction methods in the literature. We give a review of such estimation/prediction methods and carry out an extensive simulation study to compare their estimation and prediction precision. Included in the comparison are BLLS, SVD, GRAM (the generalized rank annihilation method), TLD (the trilinear decomposition method), PARAFAC (parallel factor analysis), PCR (principal components regression) and PLS (partial least squares regression). We conclude that BLLS does best both as estimator and predictor. In some circumstances PARAFAC and TLD do as well as BLLS, but with little information in the calibration set they work badly. Some of the methods do better if they are allowed to predict by a proportional multiple linear regression, whereas other methods do best when they predict with simple proportional regression.

  • Pallidal Deep Brain Stimulation in the Treatment of Huntington’s Chorea
  • 2014
  • Ingår i: Brain Disorders & Therapy. - 2168-975X. ; 3:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Despite the success of deep brain stimulation (DBS) in various movement disorders, its use in Huntington´s Disease (HD) has been limited. So far, promising results of pallidal DBS have been reported in 7 patients with HD. We performed bilateral pallidal DBS in a 59 year old woman with HD since 12 years and severe motor symptoms. At the evaluation after 12 months the effect was deemed satisfactory mainly concerning the patient’s choreatic symptoms. However, the improvement according to the unified Huntington’s disease rating scale was modest, with a score reduction from 92 to 81.

  • Enhancing Quality through Work Integrated Learning and Collaboration Partnership
  • 2022
  • Ingår i: International Conference on Work Integrated Learning. - Trollhättan : University West. - 9789189325302 ; , s. 90-91
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • For Sweden to be able to compete in the global economy, our students with a degree from higher education must be ready for a career in working life. Today's work life is facing a major ongoing transformation, characterized by increased complexity, higher specialization, and digitalization. This demands competencies beyond traditional theoretical knowledge, such as preparing for uncertainty and unknown outcomes (Barnett, 2000; Vallo Hult & Byström, 2021). Therefore, it is essential to engage students in learning to learn, i.e., lifelong learning so that the tools and methods for learning in higher education can also be developed through future work (Billett, 2014; Islind, Norström, Vallo Hult, & Ramadani Olsson, 2021). For University West, this means that our education programs must be developed in collaboration with industry partners from the surrounding society to provide arelevant and attractive education, which corresponds to the labour market's long-term competence needs. We want our students to develop abilities and skills that enable them to be part of and drive sustainable societal development in practice.Work Integrated Learning (WIL) is University West's overarching profile, based on the concept of advanced knowledge – characterized by complex problem solving – and the mutual acknowledgment of advanced knowledge within the academy and among its partners. What characterizes WIL at University West is that we have developed and refined a combination of different approaches over a long period, including research -based WIL, through fundamental learning concepts such as socio- cultural, critical and action-oriented learning theories. These influences have shaped WIL at University West into a dynamic and academic area of knowledge and subject. In order to achieve a strategic and qualitative development of work-integrated learning, the University West Board decided to WIL-certify all educational programs with a clear sustainability perspective. The quality processis called the WIL certification process. It has now been developed at the university fortwo years.Experience andrefinements are ready to mature into an overall quality framework worth conceptualizing and disseminating to more universities that systematically want to develop WIL as an explicit quality dimension in higher educa tion. The project is still ongoing but have generated some preliminary findings and outcomes from the initial phase. Data collection activities include workshops and focus groups with selected participants from the target groups at the university (managers/prefects and teachers) as well as at the collaborative partner organization (managers and supervisors/mentors). The focus of the workshops was placed on capturing the participants understanding and perspectives on WIL as a concept, and to map the conditions for and experiences of conducting WIL in teaching and learning at work. We aim for identifying good (or less good) examples of WIL, what they are, how they are understood and why they are (or are not) important.The purpose of this paper is to describe the lessons learned so far and present a conceptual quality framework for WIL in higher education with a clear connection to sustainable development. The quality framework may function as a mediating “support object” between higher education institutions, industry partners, and actors in the surrounding society to promote WIL concepts and experiences in collaboration strategies.

    • For graduates to be able to compete in the global world, study programmes must include knowledge, competences and skills that ensures that students with a higher education degree are ready for both a complex working life and continuous competence development. This demands competencies beyond traditional theoretical knowledge, such as preparing for uncertainty and unknown outcomes. Therefore, it is essential to engage students in learning to learn, i.e., lifelong learning so that the tools and methods for learning in higher education can also be developed through future work.At University West (UW) in Sweden, this means that programmes are developed in collaboration with societal partners to provide a relevant and attractive educational offer. The University West uses the concept of work-integrated learning (WIL) to embrace a sustained/systematic collaboration with strategic partners outside academia. We consider that knowledge is created in the encounter between academia and our strategic partners, through the integration of knowledge, skills and competences acquired both within academia and work life.To achieve a strategic and qualitative development of work-integrated learning (WIL), the Board of University West in 2018 decided to WIL-certify all educational programs including a sustainability perspective and enhance this process by engaging in strategic partnerships with stakeholders from civic society to international companies. The process is a development of existing and future programmes and their pedagogical approach. The WIL certification process has developed into a renewal of the pedagogical approach through a development process based on a lively exchange of experiences from study programme representatives from political science to nursing; and discussions with our strategic partners that benefits both students, staff as well as the strategic partners through competence development and lifelong learning.The purpose of this paper is to describe the lessons learned so far and present a conceptual quality framework for WIL in higher education with a clear connection to sustainable development. Based on the experiences from the development of the institutional WIL project and a Swedish Innovation agency (VINNOVA) research project we aim for a better understanding and insights into how theoretical and practical knowledge can enhance learning both within academia and within strategic partners. Data collection activities include workshops and focus groups with selected participants from the target groups at the university (managers/prefects and teachers) as well as at the collaborative partner organization (managers and supervisors/mentors). Initial findings suggest that the meeting between academia, working life and the surrounding society can ensure that insights, solutions and mutual development are created to meet the challenges society faces. The paper will discuss the methodology of creating work-integrated learning environments that include well-functioning communication and a community of practice (Wenger, 1998) connecting learners, teachers, and other staff with local, regional and national stakeholders.

  • Pharmacological agents preceding a diagnosis of immune thrombocytopenia in adult patients developing the chronic form : A Swedish national register study
  • 2017
  • Ingår i: Thrombosis Research. - : PERGAMON-ELSEVIER SCIENCE LTD. - 0049-3848 .- 1879-2472. ; 160, s. 27-31
  • Tidskriftsartikel (refereegranskat)abstract
    • Patients with primary chronic immune thrombocytopenia (cITP) have been reported to use more anti-infective medications, even before diagnosis of immune thrombocytopenia (ITP). The more common use of anti-infective medications may be due to general health problems, requiring medication in the early stages of cITP and before the diagnosis is set, rather than infections preceding the disease. Accordingly, cITP may not only be associated with use of anti-infective medications but also with medications for more general symptoms.Objective: To investigate use of medications for general symptoms, such as analgesics and vitamin supplements in patients with ITP developing the chronic form, the year preceding their first primary diagnosis in comparison with such use in the general population.Method: Swedish Health Registers were used to identify adult patients (n = 1087) with primary cITP during 2006-2012 and data on medications. Standardized Incidence Ratios (SIRs) and 95% confidence intervals (CI), were estimated as a measure of relative risk.Results: The association for overall studied medications was SIR = 1.36 (95% CI 1.32-1.41). A majority of the point estimates were above unity.Conclusion: In patients with cITP, prescription fills for medications used to treat pain conditions and vitamin deficiencies are more common in the year preceding their first diagnosis as compared with prescription fills in the general population. Our results suggest that patients later diagnosed with cITP receive treatment due to symptoms that could be signs of an early ITP. Accordingly, in investigations for unspecific pain symptoms and vitamin deficiencies, cITP should be considered as a differential diagnosis.

    • The aim of the study was to investigate the feasibility of mobilizing Philadelphia chromosome negative (Ph-) blood stem cells (BSC) with intensive chemotherapy and lenograstim (G-CSF) in patients with CML in first chronic phase (CP1). During 1994-1999 12 centers included 37 patients <56 years. All patients received 6 months' IFN, stopping at median 36 (1-290) days prior to the mobilization chemotherapy. All received one cycle of daunorubicin 50 mg/m2 and 1 hour infusion on days 1-3, and cytarabine (ara-C) 200 mg/m2 24 hours' i.v. infusion on days 1-7 (DA) followed by G-CSF 526 microg s.c. once daily from day 8 after the start of chemotherapy. Leukaphereses were initiated when the number of CD 34+ cells was >5/microl blood. Patients mobilizing poorly could receive a 4-day cycle of chemotherapy with mitoxantrone 12 mg/m2/day and 1 hour i.v infusion, etoposide 100 mg/m2/day and 1 hour i.v. infusion and ara-C 1 g/m2/twice a day with 2 hours' i.v infusion (MEA) or a second DA, followed by G-CSF 526 microg s.c once daily from day 8 after the start of chemotherapy. Twenty-seven patients received one cycle of chemotherapy and G-CSF, whereas 10 were mobilized twice. Twenty-three patients (62%) were successfully (MNC >3.5 x 10(8)/kg, CFU-GM >1.0 x 10(4)/kg, CD34+ cells >2.0 x 10(6)/kg and no Ph+ cells in the apheresis product) [n = 16] or partially successfully (as defined above but 1-34% Ph+ cells in the apheresis product) [n = 7] mobilized. There was no mortality during the mobilization procedure. Twenty-one/23 patients subsequently underwent auto-SCT. The time with PMN <0.5 x 10(9)/l was 10 (range 7-49) and with platelets <20 x 10(9)/l was also 10 (2-173) days. There was no transplant related mortality. The estimated 5-year overall survival after auto-SCT was 68% (95% CI 47 - 90%), with a median follow-up time of 5.2 years.We conclude that in a significant proportion of patients with CML in CP 1, intensive chemotherapy combined with G-CSF mobilizes Ph- BSC sufficient for use in auto-SCT.

  • Ingår i: European Journal of Orthodontics. - : Oxford University Press (OUP). - 0141-5387 .- 1460-2210. ; 34:5, s. 561-570
  • Tidskriftsartikel (refereegranskat)abstract
    • This retrospective study was carried out on consecutively collected dental casts, x-rays, and photos of 129 Swedish children who had been born with non-syndromic unilateral (U) cleft lip (CL), cleft lip and alveolus (CLA), or cleft lip and palate (CLP). The following dental characteristics were investigated in the primary and permanent dentitions: 1. the presence, eruption, position, and shape of the lateral incisor; 2. the prevalence of rotation and enamel hypoplasia of the permanent central incisor; 3. the occurrence of hypodontia outside the cleft region; and 4. the transition from the primary to the succeeding permanent lateral incisor in the cleft region. Patients with clefts involving the palate (UCLP) exhibited a high frequency of hypodontia. In patients with clefts, which did not include the palate, malformed lateral incisors were a common finding. In the primary and permanent dentition, the lateral incisor had erupted distal to the cleft in 31.8 and 24.8 per cent of the UCLA and UCLP patients, respectively. No significant pattern was seen regarding the transition from the primary to the succeeding permanent lateral incisor (P = 0.15). The central incisor was rotated in 55 per cent of the patients and this positional deviation was particularly frequent in cases where the lateral incisor was missing in the premaxilla (P < 0.05). Hypodontia outside the cleft region was recorded in 15.5 per cent of the patients. Patients with UCLP had more often crossbite than patients with a UCL or a UCLA phenotype (P < 0.001).

  • Round and round in circles-shifting relevance structures as students discuss acceleration and forces during circular motion in a vertical plane
  • 2023
  • Ingår i: European journal of physics. - : Institute of Physics (IOP). - 0143-0807 .- 1361-6404. ; 44:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Working out the relations between the forces involved in circular motion in a vertical plane can be challenging for first-year students, as illustrated in this analysis of a 30 min group discussion of a textbook problem where a remote-control model car moves with constant speed inside a cylinder. The analysis includes timelines of semiotic resources used, as well as of topics brought up by individual students. Questions from the students include: what is that force you drew on the paper? Does it act on the car or on the wall? What keeps the car from falling down? The normal force and the 'centripetal force' both point to the center-does it mean they are the same? Is it only a gravitational force at the top? Does the normal force at the bottom just cancel gravity or does it need to be larger? What is 'normal' about the normal force? Arriving at the correct numerical result is insufficient evidence for student understanding of forces in circular motion! Can students with fragmentary understanding bring their pieces together to solve the puzzle? From the timelines, we can identify a few critical moments where the discussion changes focus. This happens when one of the students in the group introduces a new dimension of variation, e.g. a reminder about the force of gravity, a free-body diagram drawn, as well as diagrams drawn in other parts of the circle than the top or bottom, where the centripetal and normal forces are no longer in the same direction. Embodied experiences are invoked, but only at a very late stage in the discussion. For teachers, an awareness of the different ways students use terms and think about the forces can be a guide to offering a larger variation in the interventions, as well as in problems assigned.

  • Ingår i: Acta Haematologica. - : S. Karger AG. - 0001-5792 .- 1421-9662. ; 113:3, s. 155-162
  • Tidskriftsartikel (refereegranskat)abstract
    • In the present study we combined interferon (IFN) and hydroxyurea (HU) treatment, intensive chemotherapy and autologous stem cell transplantation (SCT) in newly diagnosed chronic myelogenous leukemia patients aged below 56 years, not eligible for allogeneic SCT. Patients who had an HLA-identical sibling donor and no contraindication went for an allogeneic SCT (related donor, RD). After diagnosis, patients not allotransplanted received HU and IFN to keep WBC and platelet counts low. After 6 months patients with Ph-positive cells still present in the bone marrow received 1–3 courses of intensive chemotherapy. Those who became Ph-negative after IFN + HU or after 1–3 chemotherapy courses underwent autologous SCT. Some patients with poor cytogenetic response were allotransplanted with an unrelated donor (URD). IFN + HU reduced the percentage of Ph-positive metaphases in 56% of patients, and 1 patient became Ph-negative. After one or two intensive cytotherapies 86 and 88% had a Ph reduction, and 34 and 40% became Ph-negative, respectively. In patients receiving a third intensive chemotherapy 92% achieved a Ph reduction and 8% became Ph-negative. The median survival after auto-SCT (n = 46) was 7.5 years. The chance of remaining Ph-negative for up to 10 years after autologous SCT was around 20%. The overall survival for allo-SCT RD (n = 91) and URD (n = 28) was almost the same, i.e. ≈60% at 10 years. The median survival for all 251 patients registered was 8 years (historical controls 3.5 years). The role of the treatment schedule presented in the imatinib era is discussed.

    • In this double-blind, placebo-controlled study, 363 patients with untreated multiple myeloma were randomized to receive either melphalan-prednisone and thalidomide (MPT) or melphalan-prednisone and placebo (MP). The dose of melphalan was 0.25 mg/kg and prednisone was 100 mg given daily for 4 days every 6 weeks until plateau phase. The dose of thalidomide/placebo was escalated to 400 mg daily until plateau phase and thereafter reduced to 200 mg daily until progression. A total of 357 patients were analyzed. Partial response was 34% and 33%, and very good partial response or better was 23% and 7% in the MPT and MP arms, respectively (P < .001). There was no significant difference in progression-free or overall survival, with median survival being 29 months in the MPT arm and 32 months in the MP arm. Most quality of life outcomes improved equally in both arms, apart from constipation, which was markedly increased in the MPT arm. Constipation, neuropathy, non-neuropathy neurologic toxicity, and skin reactions were significantly more frequent in the MPT arm. The number of thromboembolic events was equal in the 2 treatment arms. In conclusion, MPT had a significant antimyeloma effect, but this did not translate into improved survival. This trial was registered at www.clinicaltrials.
