    Iron depletion in blood donors - Have extended erythrocyte and reticulocyte parameters diagnostic utility?2015In: Transfusion and apheresis science, ISSN 1473-0502, E-ISSN 1878-1683, Vol. 53, no 1, 76-81 p.Article in journal (Refereed)
    Abstract [en]

    Background: Blood donation is associated with iron depletion, but donor iron status is not usually investigated, as such tests are cumbersome and costly. It would therefore be desirable to have simple, fast and inexpensive tests that give information on a donors risk of developing iron depletion. In a pilot study we investigated whether novel erythrocyte and reticulocyte parameters can serve this goal. Methods: In regular blood donors extended red cell parameters were measured using the Abbott CELL-DYN Sapphire hematology analyzer and conventional biochemical tests of iron status. Donors were compared with a regionally matched group of non-donating controls. Results: In the controls, the reference ranges of extended RBC parameters were well comparable to published data. Donors had significantly more microcytic RBC than controls (median 0.9 vs 0.6%), lower serum ferritin concentration (median 43 vs 91 mg/L) and higher soluble transferrin receptor/ferritin index (median 1.60 vs 1.27). Overall 18-28% of the donors were iron depleted. Moreover, 3.3% of donors had iron-restricted erythropoiesis. Microcytic RBC and reticulocyte mean cell hemoglobin content predicted iron depletion with 70% and 64% sensitivities and specificities of 72% and 78%, respectively. When combined these two parameters increased the sensitivity to 82%. Conclusions: Our results in Swedish blood donors confirm a high prevalence of iron depletion, despite iron supplementation used by about half of the donors. Microcytic RBC and MCHr appeared to be helpful in identifying iron-depleted donors, who might benefit from iron supplementation. We recommend larger prospective investigations in order to confirm and extend the findings of this pilot study. (C) 2015 Elsevier Ltd. All rights reserved.

    Validate or falsify: Lessons learned from a microscopy method claimed to be useful for detecting Borrelia and Babesia organisms in human blood2016In: INFECTIOUS DISEASES, ISSN 2374-4235, Vol. 48, no 6, 411-419 p.Article in journal (Refereed)
    Abstract [en]

    Background A modified microscopy protocol (the LM-method) was used to demonstrate what was interpreted as Borrelia spirochetes and later also Babesia sp., in peripheral blood from patients. The method gained much publicity, but was not validated prior to publication, which became the purpose of this study using appropriate scientific methodology, including a control group. Methods Blood from 21 patients previously interpreted as positive for Borrelia and/or Babesia infection by the LM-method and 41 healthy controls without known history of tick bite were collected, blinded and analysed for these pathogens by microscopy in two laboratories by the LM-method and conventional method, respectively, by PCR methods in five laboratories and by serology in one laboratory. Results Microscopy by the LM-method identified structures claimed to be Borrelia- and/or Babesia in 66% of the blood samples of the patient group and in 85% in the healthy control group. Microscopy by the conventional method for Babesia only did not identify Babesia in any samples. PCR analysis detected Borrelia DNA in one sample of the patient group and in eight samples of the control group; whereas Babesia DNA was not detected in any of the blood samples using molecular methods. Conclusions The structures interpreted as Borrelia and Babesia by the LM-method could not be verified by PCR. The method was, thus, falsified. This study underlines the importance of doing proper test validation before new or modified assays are introduced.

    Treatment strategies in Alzheimers disease: a review with focus on selenium supplementation2016In: Biometals, ISSN 0966-0844, E-ISSN 1572-8773, Vol. 29, no 5, 827-839 p.Article in journal (Refereed)
    Abstract [en]

    Alzheimers disease (AD) is a neurodegenerative disorder presenting one of the biggest healthcare challenges in developed countries. No effective treatment exists. In recent years the main focus of AD research has been on the amyloid hypothesis, which postulates that extracellular precipitates of beta amyloid (A beta) derived from amyloid precursor protein (APP) are responsible for the cognitive impairment seen in AD. Treatment strategies have been to reduce A beta production through inhibition of enzymes responsible for its formation, or to promote resolution of existing cerebral A beta plaques. However, these approaches have failed to demonstrate significant cognitive improvements. Intracellular rather than extracellular events may be fundamental in AD pathogenesis. Selenate is a potent inhibitor of tau hyperphosphorylation, a critical step in the formation of neurofibrillary tangles. Some selenium (Se) compounds e.g. selenoprotein P also appear to protect APP against excessive copper and iron deposition. Selenoproteins show anti-inflammatory properties, and protect microtubules in the neuronal cytoskeleton. Optimal function of these selenoenzymes requires higher Se intake than what is common in Europe and also higher intake than traditionally recommended. Supplementary treatment with N-acetylcysteine increases levels of the antioxidative cofactor glutathione and can mediate adjuvant protection. The present review discusses the role of Se in AD treatment and suggests strategies for AD prevention by optimizing selenium intake, in accordance with the metal dysregulation hypothesis. This includes in particular secondary prevention by selenium supplementation to elderly with mild cognitive impairment.

    Asymptomatic Helminth Infection in Active Tuberculosis Is Associated with Increased Regulatory and Th-2 Responses and a Lower Sputum Smear Positivity2015In: PLoS Neglected Tropical Diseases, ISSN 1935-2727, E-ISSN 1935-2735, Vol. 9, no 8, e0003994Article in journal (Refereed)
    Abstract [en]

    Background The impact of intestinal helminth infection on the clinical presentation and immune response during active tuberculosis (TB) infection is not well characterized. Our aim was to investigate whether asymptomatic intestinal helminth infection alters the clinical signs and symptoms as well as the cell mediated immune responses in patients with active TB.

    Methodology Consecutive, newly diagnosed TB patients and healthy community controls (CCs) were recruited in North-west Ethiopia. TB-score, body mass index and stool samples were analyzed. Cells from HIV-negative TB patients (HIV-/TB) and from CCs were analyzed for regulatory T-cells (Tregs) and cytokine responses using flow cytometry and ELISPOT, respectively.

    Results A significantly higher ratio of helminth co-infection was observed in TB patients without HIV (Helm+/HIV-/TB) compared to HIV negative CCs, (40% (121/306) versus 28% (85/306), p = 0.003). Helm+/HIV-/TB patients showed significantly increased IL-5 secreting cells compared to Helm-/HIV-/TB (37 SFU (IQR:13-103) versus 2 SFU (1-50); p = 0.02, n = 30). Likewise, levels of absolute Tregs (9.4 (3.2-16.7) cells/mu l versus 2.4 (1.1-4.0) cells/mu l; p = 0.041) and IL-10 secreting cells (65 SFU (7-196) versus 1 SFU (0-31); p = 0.014) were significantly higher in Helm+/HIV-/TB patients compared to Helm-/HIV-/TB patients. In a multivariate analysis, a lower rate of sputum smear positivity for acid fast bacilli, lower body temperature, and eosinophilia were independently associated with helminth infection in TB patients.

    Conclusions Asymptomatic helminth infection is associated with increased regulatory T-cell and Th2-type responses and a lower rate of sputum smear positivity. Further studies are warranted to investigate the clinical and immunological impact of helminth infection in TB patients.

    Aesthetic Outcome After Reconstruction of Complex SoftTissue Defects with Free Antero-Lateral Thigh Flap UsingSimple Equipment2015In: Journal of surgery, ISSN 2330-0914, Vol. 3, no 2-1, 36-41 p.Article in journal (Refereed)
    Abstract [en]

    Aim: We aimed to assess the aesthetic outcome of surgical reconstruction by free ALT flap using binocular single-refraction magnifying glasses and a modified post- operative surveillance protocol. Methods: 16 patients were operated for free antero-lateral thigh flap to reconstruct complex soft tissue defects with a close clinical follow up protocol for post operative care depending on the attending personnel in the Plastic surgery unit, Suez Canal University hospital, Ismailia, Egypt. Aesthetic outcome was assessed using a questionnaire based on Posch et al. 2005, including the following items colour, contour, presence of hair, overall appearance and donor site scar. Results: The patients’ assessed aesthetic outcome was acceptable in majority of the cases; median score was 4 for all assessed items. Complete flap loss occurred in one case, other complications as arterial thrombosis and hematomas and infection were detected and managed accordingly with flap salvage in the 3 complicated cases. Conclusion: The result suggests that the proposed protocol is sufficient as an alternative. The aesthetic outcome assessed by the patient and the failure rate was in line with other studies.

    Evidence base and future research directions in the management of low back pain2016In: World Journal of Orthopedics, ISSN 2218-5836, E-ISSN 2218-5836, Vol. 7, no 3, 156-161 p.Article in journal (Other academic)
    Abstract [en]

    Low back pain (LBP) is a prevalent and costly condition. Awareness of valid and reliable patient history taking, physical examination and clinical testing is important for diagnostic accuracy. Stratified care which targets treatment to patient subgroups based on key characteristics is reliant upon accurate diagnostics. Models of stratified care that can potentially improve treatment effects include prognostic risk profiling for persistent LBP, likely response to specific treatment based on clinical prediction models or suspected underlying causal mechanisms. The focus of this editorial is to highlight current research status and future directions for LBP diagnostics and stratified care.

    Risk of Rectal Cancer After Colectomy for Patients With Ulcerative Colitis: A National Cohort Study2017In: Clinical Gastroenterology and Hepatology, ISSN 1542-3565, E-ISSN 1542-7714, Vol. 15, no 7, 1055-+ p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND amp; AIMS: Patients with ulcerative colitis (UC) have an increased risk of rectal cancer, therefore reconstruction with an ileal pouch-anal anastomosis (IPAA) generally is preferred to an ileorectal anastomosis (IRA) after subtotal colectomy. Similarly, completion proctectomy is recommended for patients with ileostomy and a diverted rectum, although this approach has been questioned because anti-inflammatory agents might reduce cancer risk. We performed a national cohort study in Sweden to assess the risk of rectal cancer in patients with UC who have an IRA, IPAA, or diverted rectum after subtotal colectomy. METHODS: We collected data from the Swedish National Patient Register for a cohort of 5886 patients with UC who underwent subtotal colectomy with an IRA, IPAA, or diverted rectum from 1964 through 2010. Patients who developed rectal cancer were identified from the Swedish National Cancer Register. The risk of rectal cancer was compared between this cohort and the general population by standardized incidence ratio analysis. RESULTS: Rectal cancer occurred in 20 of 1112 patients (1.8%) who received IRA, 1 of 1796 patients (0.06%) who received an IPAA, and 25 of 4358 patients (0.6%) with a diverted rectum. Standardized incidence ratios for rectal cancer were 8.7 in patients with an IRA, 0.4 in patients with an IPAA, and 3.8 in patients with a diverted rectum. Risk factors for rectal cancer were primary sclerosing cholangitis in patients with an IRA (hazard ratio, 6.12), and colonic severe dysplasia or cancer before subtotal colectomy in patients with a diverted rectum (hazard ratio, 3.67). CONCLUSIONS: In an analysis of the Swedish National Patient Register, we found that the risk for rectal cancer after colectomy in patients with UC is low, in relative and absolute terms, after reconstruction with an IPAA. An IRA and diverted rectum are associated with an increased risk of rectal cancer, compared with the general population, but the absolute risk is low. Patients and their health care providers should consider these findings in making decisions to leave the rectum intact, perform completion proctectomy, or reconstruct the colon with an IRA or IPAA.

    Division of overall duration of stay into operative stay and postoperative stay improves the overall estimate as a measure of quality of outcome in burn care.2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 3, e0174579Article in journal (Refereed)
    Abstract [en]

    Patients and Methods: Surgically managed burn patients admitted between 2010-14 were included. Operative stay was defined as the time from admission until the last operation, postoperative stay as the time from the last operation until discharge. The difference in variation was analysed with F-test. A retrospective review of medical records was done to explore reasons for extended postoperative stay. Multivariable regression was used to assess factors associated with operative stay and postoperative stay.less thanbr /greater thanResults: Operative stay/TBSA% showed less variation than total duration/TBSA% (F test = 2.38, pless than0.01). The size of the burn, and the number of operations, were the independent factors that influenced operative stay (R2 0.65). Except for the size of the burn other factors were associated with duration of postoperative stay: wound related, psychological and other medical causes, advanced medical support, and accommodation arrangements before discharge, of which the two last were the most important with an increase of (mean) 12 and 17 days (pless than0.001, R2 0.51).less thanbr /greater thanConclusion: Adjusted operative stay showed less variation than total hospital stay and thus can be considered a more accurate outcome measure for surgically managed burns. The size of burn and number of operations are the factors affecting this outcome measure.

    Improvement in mortality at a National Burn Centre since 2000: Was it the result of increased resources?2017In: Medicine (Baltimore, Md.), ISSN 0025-7974, E-ISSN 1536-5964, Vol. 96, no 25, e6727Article in journal (Refereed)
    Abstract [en]

    Abstract The aim of this study was to find out whether the charging costs (calculated using interventional burn score) increased as mortality decreased. During the last 2 decades, mortality has declined significantly in the Linköping Burn Centre. The burn score that we use has been validated as a measure of workload and is used to calculate the charging costs of each burned patient. We compared the charging costs and mortality in 2 time periods (2000–2007 and 2008–2015). A total of 1363 admissions were included. We investigated the change in the burn score, as a surrogate for total costs per patient. Multivariable regression was used to analyze risk-adjusted mortality and burn score. The median total body surface area % (TBSA%) was 6.5% (10–90 centile 1.0–31.0), age 33 years (1.3–72.2), duration of stay/ TBSA% was 1.4 days (0.3–5.3), and 960 (70%) were males. Crude mortality declined from 7.5% in 2000–2007 to 3.4% in 2008–2015, whereas the cumulative burn score was not increased (P=.08). Regression analysis showed that risk-adjusted mortality decreased (odds ratio 0.42, P=.02), whereas the adjusted burn score did not change (P=.14, model R2 0.86). Mortality decreased but there was no increase in the daily use of resources as measured by the interventional burn score. The data suggest that the improvements in quality obtained have been achieved within present routines for care of patients (multidisciplinary/ orientated to patients’ safety).

    A prospective randomized cost billing comparison of local fasciocutaneous perforator versus free Gracilis flap reconstruction for lower limb in a developing economy2016In: Journal of Plastic, Reconstructive & Aesthetic Surgery, ISSN 1748-6815, E-ISSN 1532-1959, Vol. 69, no 8, 1121-1127 p.Article in journal (Refereed)
    Abstract [en]

    Distal half leg complex wounds are usually a formidable problem that necessitates either local or free flap coverage. The aim of this study was to compare cost billing charges in free Gracilis flap (fGF) and local fasciocutaneous perforator flap (lFPF) in reconstructing complex soft tissue leg and foot defects. Patients and methods: Thirty consecutive adult (amp;gt; 15-year-old) patients with soft tissue defects in the leg and/or foot requiring tissue coverage with a flap in the period between 2012 and 2015 were randomly assigned (block randomization) to either an fGF or lFPF procedure. The outcome measures addressed were total billed charges costs, perioperative billed charges cost, partial or complete flap loss, length of hospital stay, inpatient postsurgical care duration, complications, operating time and number of operative scrub staff. Results: One patient suffered from complete flap loss in each group. Reconstruction with lFPF showed total lower billed charges costs by 62% (2509 USD) (p amp;lt; 0.001) and perioperative billed charges cost by 54% (779 USD) (p amp;lt; 0.001), and shorter total hospital stay (36.5 days; p amp;lt; 0.001), inpatient postsurgical care duration (6.4 days; p amp;lt; 0.001), operating time (4.3 h; p amp;lt; 0.001) and fewer scrub staff (2.2 persons; p amp;lt; 0.001). Conclusion: These results suggest that neither flap is totally superior to the other; the choice should instead be based on the outcome sought and logistics. lFPF requires lower billed charges cost and resource use and saves operative time and personnel and reduces length of hospital stay. Our approach changed towards using perforator flaps in medium-sized defects, keeping the free flap option for larger defects.

    The Placental Immune Milieu is Characterized by a Th2- and Anti-Inflammatory Transcription Profile, Regardless of Maternal Allergy, and Associates with Neonatal Immunity2015In: American Journal of Reproductive Immunology, ISSN 1046-7408, E-ISSN 1600-0897, Vol. 73, no 5, 445-459 p.Article in journal (Refereed)
    Abstract [en]

    PROBLEM: How maternal allergy affects the systemic and local immunological environment during pregnancy and the immune development of the offspring is unclear.

    METHOD OF STUDY: Expression of 40 genes was quantified by PCR arrays in placenta, peripheral blood mononuclear cells (PBMC), and cord blood mononuclear cells (CBMC) from 7 allergic and 12 non-allergic women and their offspring.

    RESULTS: Placental gene expression was dominated by a Th2-/anti-inflammatory profile, irrespectively of maternal allergy, as compared to gene expression in PBMC. p35 expression in placenta correlated with fetal Tbx21 (ρ = -0.88, P < 0.001) and IL-5 expression in PBMC with fetal galectin1 (ρ = 0.91, P < 0.001). Increased expression of Th2-associated CCL22 in CBMC preceded allergy development.

    CONCLUSIONS: Gene expression locally and systemically during pregnancy was partly associated with the offspring's gene expression, possibly indicating that the immunological milieu is important for fetal immune development. Maternal allergy was not associated with an enhanced Th2 immunity in placenta or PBMC, while a marked prenatal Th2 skewing, shown as increased CCL22 mRNA expression, might contribute to postnatal allergy development.

    Strategies to Overcome Barriers to Implementation of Alcohol Screening and Brief Intervention in General Practice: a Delphi Study Among Healthcare Professionals and Addiction Prevention Experts2016In: Prevention Science, ISSN 1389-4986, E-ISSN 1573-6695, Vol. 17, no 6, 689-699 p.Article in journal (Refereed)
    Abstract [en]

    Despite the evidence base, alcohol screening and brief intervention (ASBI) have rarely been integrated into routine clinical practice. The aim of this study is to identify strategies that could tackle barriers to ASBI implementation in general practice by involving primary healthcare professionals and addiction prevention experts. A three-round online Delphi study was carried out in the Netherlands. The first-round questionnaire consisted of open-ended questions to generate ideas about strategies to overcome barriers. In the second round, participants were asked to indicate how applicable they found each strategy. Items without consensus were systematically fed back with group median ratings and interquartile range (IQR) scores in the third-round questionnaire. In total, 39 out of 69 (57 %) invited participants enrolled in the first round, 214 participants completed the second round, and 144 of these (67 %) completed the third-round questionnaire. Results show that participants reached consensus on 59 of 81 strategies, such as the following: (1) use of E-learning technology, (2) symptom-specific screening by general practitioners (GPs) and/or universal screening by practice nurses, (3) reimbursement incentives, (4) supportive materials, (5) clear guidelines, (6) service provision of addiction care centers, and (7) more publicity in the media. This exploratory study identified a broad set of strategies that could potentially be used for overcoming barriers to ASBI implementation in general practice and paves the way for future research to experimentally test the identified implementation strategies using multifaceted approaches.

    Tissue specific expression of extracellular microRNA in human breast cancers and normal human breast tissue in vivo2015In: OncoTarget, ISSN 1949-2553, E-ISSN 1949-2553, Vol. 6, no 26, 22959-22969 p.Article in journal (Refereed)
    Abstract [en]

    Extracellular circulating microRNAs (miRNAs) have been suggested to be biomarkers for disease monitoring but data are inconsistent, one reason being that blood miRNA is of heterogeneous origin. Here, we sampled extracellular microRNAs locally in situ using microdialysis. Three different cohorts of women were included; postmenopausal women with ongoing breast cancer investigated within the cancer and in normal adjacent breast tissue, postmenopausal women investigated in their normal healthy breast and subcutaneous fat before and after six weeks of tamoxifen therapy, premenopausal women during the menstrual cycle. Samples were initially screened using TaqMan array cards with subsequently absolute quantification. 124 miRNA were expressed in microdialysates. After absolute quantifications extracellular miRNA-21 was found to be significantly increased in breast cancer. In addition, the levels were significantly higher in pre-menopausal breast tissue compared with postmenopausal. In breast tissue of pre-menopausal women miRNA-21 exhibited a cyclic variation during the menstrual cycle and in postmenopausal women six weeks of tamoxifen treatment decreased miRNA-21 suggesting that this miRNA may be important for breast carcinogenesis. None of these changes were found in plasma or microdialysates from subcutaneous fat. Our data revealed tissue specific changes of extracellular circulating miRNAs that would be otherwise unraveled using blood samples.

    Increased nutrient availability in dense breast tissue of postmenopausal women in vivo2017In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 7, 42733Article in journal (Refereed)
    Abstract [en]

    Metabolic reprogramming is a hallmark of cancer. Nutrient availability in the tissue microenvironment determines cellular events and may play a role in breast carcinogenesis. High mammographic density is an independent risk factor for breast cancer. Whether nutrient availability differs in normal breast tissues with various densities is unknown. Therefore we investigated whether breast tissues with various densities exhibited differences in nutrient availability. Healthy postmenopausal women from the regular mammographic screening program who had either predominantly fatty breast tissue (nondense), n = 18, or extremely dense breast tissue (dense), n = 20, were included. Microdialysis was performed for the in vivo sampling of amino acids (AAs), analyzed by ultra-high performance liquid chromatography with tandem mass spectroscopy, glucose, lactate and vascular endothelial growth factor (VEGF) in breast tissues and, as a control, in abdominal subcutaneous (s.c.) fat. We found that dense breast tissue exhibited significantly increased levels of 20 proteinogenic AAs and that 18 of these AAs correlated significantly with VEGF. No differences were found in the s.c. fat, except for one AA, suggesting tissue-specific alterations in the breast. Glucose and lactate were unaltered. Our findings provide novel insights into the biology of dense breast tissue that may be explored for breast cancer prevention strategies.

    Dense breast tissue in postmenopausal women is associated with a pro-inflammatory microenvironment in vivo2016In: Oncoimmunology, ISSN 2162-4011, E-ISSN 2162-402X, Vol. 5, no 10, e1229723Article in journal (Refereed)
    Abstract [en]

    Inflammation is one of the hallmarks of carcinogenesis. High mammographic density has been associated with increased risk of breast cancer but the mechanisms behind are poorly understood. We evaluated whether breasts with different mammographic densities exhibited differences in the inflammatory microenvironment.Postmenopausal women attending the mammography-screening program were assessed having extreme dense, n = 20, or entirely fatty breasts (nondense), n = 19, on their regular mammograms. Thereafter, the women were invited for magnetic resonance imaging (MRI), microdialysis for the collection of extracellular molecules in situ and a core tissue biopsy for research purposes. On the MRI, lean tissue fraction (LTF) was calculated for a continuous measurement of breast density. LTF confirmed the selection from the mammograms and gave a continuous measurement of breast density. Microdialysis revealed significantly increased extracellular in vivo levels of IL-6, IL-8, vascular endothelial growth factor, and CCL5 in dense breast tissue as compared with nondense breasts. Moreover, the ratio IL-1Ra/IL-1 was decreased in dense breasts. No differences were found in levels of IL-1, IL-1Ra, CCL2, leptin, adiponectin, or leptin:adiponectin ratio between the two breast tissue types. Significant positive correlations between LTF and the pro-inflammatory cytokines as well as between the cytokines were detected. Stainings of the core biopsies exhibited increased levels of immune cells in dense breast tissue.Our data show that dense breast tissue in postmenopausal women is associated with a pro-inflammatory microenvironment and, if confirmed in a larger cohort, suggests novel targets for prevention therapies for women with dense breast tissue.

    Gut microbiota and allergy: the importance of the pregnancy period2015In: Pediatric Research, ISSN 0031-3998, E-ISSN 1530-0447, Vol. 77, no 1, 214-219 p.Article, review/survey (Refereed)
    Abstract [en]

    Limited microbial exposure is suggested to underlie the increase of allergic diseases in affluent countries, and bacterial diversity seems to be more important than specific bacteria taxa. Prospective studies indicate that the gut microbiota composition during the first months of life influences allergy development, and support the theory that factors influencing the early maturation of the immune system might be important for subsequent allergic disease. However, recent research indicates that microbial exposure during pregnancy may be even more important for the preventative effects against allergic disease. This review gives a background of the epidemiology, immunology, and microbiology literature in this field. It focuses on possible underlying mechanisms such as immune-regulated epigenetic imprinting and bacterial translocation during pregnancy, potentially providing the offspring with a pioneer microbiome. We suggest that a possible reason for the initial exposure of bacterial molecular patterns to the fetus in utero is to prime the immune system and/or the epithelium to respond appropriately to pathogens and commensals after birth.

    I takt med framtiden: Utveckling av ett nytt interprofessionellt curriculum vid Hälsouniversitetet i Linköping2015Report (Other academic)
    Abstract [sv]

    Hälso- och sjukvårdsutbildningarnas ansvar att utbilda professionella som kan samarbetaoch förstå varandras kompetens, för att utföra och utveckla patientsäker vård, betonas alltmer i den globala debatten om framtidens hälso- och sjukvård. Modern professionsutbildning inom hälso- och sjukvården måste idag därför innehålla moment av god kvalitet där studenter lär med, av och om varandra för att utveckla interprofessionell kompetens. Hälsouniversitetet i Linköping är pionjär, både nationellt och internationellt, när det gäller interprofessionellt lärande tack vare satsningen på integrerade utbildningsmoment som funnits med sedan från starten 1986. Den här rapporten är en sammanställning av den interna process som har genomförts för att initiera ett pedagogiskt utvecklingsprojekt med avsikt att revidera och utveckla dessa gemensamma utbildningsmoment inriktade mot interprofessionellt lärande. Texten är upplagd kronologiskt och inleds med det direktiv som fakultetsledningen gav för att en utvald grupp lärare skulle kunna utarbeta ett förslag på hur de interprofessionella lärandemomenten vid Hälsouniversitetet skulle kunna förbättras. Härefter följer den rapport som utredningsgruppen lämnade, och som sedan skickades på remiss till olika intressenter. Rapporten följs av en sammanställning och bearbetning av de inkomna remissvaren och till sist följer fakultetsstyrelsens beslut om hur curriculum för interprofessionell utbildning inom Hälsouniversitetet ska utvecklas eller förändras. Det är vår förhoppning att dokumentationen av processen för att förnya fakultetens interprofessionella utbildning ska ge inspiration för fortsatt förändrings- och utvecklingsarbete både inom och utom Linköpings universitet.

    Theorising simulation in higher education: difficulty for learners as an emergent phenomenon2016In: Teaching in Higher Education, ISSN 1356-2517, E-ISSN 1470-1294, Vol. 21, no 6, 613-627 p.Article in journal (Refereed)
    Abstract [en]

    Despite the widespread interest in using and researching simulation in higher education, little discussion has yet to address a key pedagogical concern: difficulty. A sociomaterial view of learning, explained in this paper, goes beyond cognitive considerations to highlight dimensions of material, situational, representational and relational difficulty confronted by students in experiential learning activities such as simulation. In this paper we explore these dimensions of difficulty through three contrasting scenarios of simulation education. The scenarios are drawn from studies conducted in three international contexts: Australia, Sweden and the UK, which illustrate diverse approaches to simulation and associated differences in the forms of difficulty being produced. For educators using simulation, the key implications are the importance of noting and understanding (1) the effects on students of interaction among multiple forms of difficulty; (2) the emergent and unpredictable nature of difficulty; and (3) the need to teach students strategies for managing emergent difficulty.

    The in silico identification and characterization of a bread wheat/Triticum militinae introgression line: Characterization of alien introgression in wheat2017In: Plant Biotechnology Journal, ISSN 1467-7644, E-ISSN 1467-7652, Vol. 15, no 2, 249-256 p.Article in journal (Refereed)
    Abstract [en]

    The capacity of the bread wheat (Triticum aestivum) genome to tolerate introgression from related genomes can be exploited for wheat improvement. A resistance to powdery mildew expressed by a derivative of the cross bread wheat cv. Tähti ⨯ T. militinae (Tm) is known to be due to the incorporation of a Tm segment into the long arm of chromosome 4A. Here, a newly developed in silico method termed RICh (rearrangement identification and characterization) has been applied to characterize the introgression. A virtual gene order, assembled using the GenomeZipper approach, was obtained for the native copy of chromosome 4A; it incorporated 570 4A DArTseq markers to produce a zipper comprising 2,132 loci. A comparison between the native and introgressed forms of the 4AL chromosome arm showed that the introgressed region is located at the distal part of the arm. The Tm segment, derived from chromosome 7G, harbors 131 homoeologs out of the 357 genes present on the corresponding region of Chinese Spring 4AL. The estimated number of Tm genes transferred along with the disease resistance gene was 169. Characterizing the introgression's position, gene content and internal gene order should facilitate not only gene isolation, but may also be informative with respect to chromatin structure and behavior studies.

    Randomised trial of bisphosphonate-coated dental implants: Radiographic follow-up after five years of loading2016In: International Journal of Oral and Maxillofacial Surgery, ISSN 0901-5027, E-ISSN 1399-0020, Vol. 45, no 12, 1564-1569 p.Article in journal (Refereed)
    Abstract [en]

    The results of a randomised trial with bisphosphonate-coated dental implants have been reported previously. Each patient received one coated and one uncoated implant in a double-blind split-mouth design study. After 6 months of osseointegration, resonance frequency analysis indicated better fixation of the coated implants. Reduced marginal bone resorption was also shown. However, it was not known whether the advantage of the bisphosphonate coating would persist over time. The radiographic results at 5 years after implant installation are reported herein. A blinded investigator measured marginal resorption on fresh radiographs obtained for 14 of the 16 patients (two had died) and compared these with the post-implantation images. Non-parametric statistics were used. All implants functioned well. The median marginal bone loss for control implants was found to be 0.70 mm, which is less than usually reported in the literature. The bisphosphonate-coated implants showed even less resorption (median 0.20 mm). The median difference within each pair of implants after 5 years of use was 0.34 mm (95% confidence interval 0.00-0.75 mm; P = 0.04). The present data suggest that bisphosphonate-coated implants enable prolonged preservation of the marginal bone.

    Positive Effects of a Weighted Blanket on Insomnia2015In: Journal of Sleep Medicine & Disorders, ISSN 2379-0822, Vol. 2, no 3, 1-7 p.Article in journal (Refereed)
    Abstract [en]

    Insomnia is a common occurrence and can have a negative impact on physiological, psychological and social well-being. There is a need for simple, effective solutions to increase sleep quality. It has been suggested that weighted blankets and vests can provide a beneficial calming effect, especially in clinical disorders. Hence, we aimed to investigate the effects of a chain weighted blanket on insomnia, using objective and subjective measures. Objectively, we found that sleep bout time increased, as well as a decrease in movements of the participants, during weighted blanket use. Subjectively, the participants liked sleeping with the blanket, found it easier to settle down to sleep and had an improved sleep, where they felt more refreshed in the morning. Overall, we found that when the participants used the weighted blanket, they had a calmer night’s sleep. A weighted blanket may aid in reducing insomnia through altered tactile inputs, thus may provide an innovative, non-pharmacological approach and complementary tool to improve sleep quality.

    Policies for managing emergency medical services in mass casualty incidents2017In: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 48, no 9, 1878-1883 p.Article in journal (Refereed)
    Abstract [en]

    Introduction: Diverse decision-making is needed in managing mass casualty incidents (MCIs), by emergency medical services (EMS). The aim of the study was to review consensus among international experts concerning policies of EMS management during MCIs. Methods: Applicability of 21 EMS policies was tested through a 2-cycle modified e-Delphi process, in which 38 multi-disciplinary experts from 10 countries participated. Threshold for approving proposed solutions was defined as consensus of amp;gt;80%. Policies that did not achieve the targeted consensus were reviewed to detect variability according to respondents origin country. Results: 16 policies were endorsed in the first cycle including collaboration between ambulance service providers; implementing a unified mode of operation; preparing criteria for ground versus aerial evacuation; and, developing support systems for caregivers exposed to violence. An additional policy which proposed that senior EMS officers should not necessarily act as on-site MCI commanders was endorsed in the second cycle. Demographic breakdown of views concerning non-consensual policies revealed differences according to countries of origin. Assigning ambulances to off-duty team members was highly endorsed by experts from Israel and South Africa and strongly rejected by European respondents. Avoiding entry to risk areas until declared safe was endorsed by European, Asian and Oceanic experts, but rejected by Israeli, South African and North American experts. Conclusions: Despite uniqueness of countries and EMS agencies, solutions to most dilemmas were applicable to all organizations, regardless of location or affiliation. Cultural diversity was found concerning readiness to implement military-civilian collaboration in MCIs and a rigid separation between work-leisure responsibilities. (C) 2017 Elsevier Ltd.

    Extensive soft tissue lesions in redislocated after simple elbow dislocations2017In: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 26, no 7, 1294-1297 p.Article in journal (Refereed)
    Abstract [en]

    Background: The majority of simple elbow dislocations (no associated fractures) can be treated nonoperatively with a short period of immobilization followed by guided aftercare. This case series describes the soft tissue injuries in a rare subset of patients in whom the elbow redislocated despite adequate immobilization. Methods: During a 6-year period, 8 patients were identified. They were all treated with reduction and casting in 90 degrees of flexion or more. At 1 week of follow-up, redislocation had occurred in all patients and open soft tissue repair was performed. The injuries were documented and the patients were followed up clinically and with radiographs. Results: Extensive soft tissue injuries, including both collateral ligament injuries and muscle origin avulsions from either or both sides, were found in all patients. The functional result at follow-up was satisfactory in all patients. Conclusion: Vast soft tissue injuries including both collateral ligaments and muscle origins should be expected in the event of early severe instability of a dislocated elbow joint.

    Effect of Neutrophils on Nitric Oxide Production from Stimulated Macrophages2015In: Iranian Journal of Immunology, ISSN 1735-1383, E-ISSN 1735-367X, Vol. 12, no 2, 94-103 p.Article in journal (Refereed)
    Abstract [en]

    Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whether the entry of neutrophils and release of arginase can interfere with nitric oxide production from stimulated mouse macrophages. Methods: Neutrophils were isolated from human blood and stimulated with cytodex-3 beads. Cultured macrophages were stimulated with lipopolysaccharide and interferon gamma with or without N (G)-nitro-L-arginine methyl ester or N (omega)-hydroxy-nor-L-arginine. Measurement of NO2-/NO3- and urea were done using the spectrophotometer. Results: A significantly higher level of nitric oxide production from stimulated macrophages was observed compared to control. There was a decrease in nitric oxide production when stimulated macrophages were treated with the supernatant from activated neutrophils (pless than0.05). Conclusion: Arginase from neutrophils can modulate nitric oxide production from activated macrophages which may affect the course of infection by intracellular bacteria.

    Pooled individual patient data from five countries were used to derive a clinical prediction rule for coronary artery disease in primary care.2017In: Journal of Clinical Epidemiology, ISSN 0895-4356, E-ISSN 1878-5921, Vol. 81, 120-128 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To construct a clinical prediction rule for coronary artery disease (CAD) presenting with chest pain in primary care.

    STUDY DESIGN AND SETTING: Meta-Analysis using 3,099 patients from five studies. To identify candidate predictors, we used random forest trees, multiple imputation of missing values, and logistic regression within individual studies. To generate a prediction rule on the pooled data, we applied a regression model that took account of the differing standard data sets collected by the five studies.

    RESULTS: The most parsimonious rule included six equally weighted predictors: age ≥55 (males) or ≥65 (females) (+1); attending physician suspected a serious diagnosis (+1); history of CAD (+1); pain brought on by exertion (+1); pain feels like "pressure" (+1); pain reproducible by palpation (-1). CAD was considered absent if the prediction score is <2. The area under the ROC curve was 0.84. We applied this rule to a study setting with a CAD prevalence of 13.2% using a prediction score cutoff of <2 (i.e., -1, 0, or +1). When the score was <2, the probability of CAD was 2.1% (95% CI: 1.1-3.9%); when the score was ≥ 2, it was 43.0% (95% CI: 35.8-50.4%).

    CONCLUSIONS: Clinical prediction rules are a key strategy for individualizing care. Large data sets based on electronic health records from diverse sites create opportunities for improving their internal and external validity. Our patient-level meta-analysis from five primary care sites should improve external validity. Our strategy for addressing site-to-site systematic variation in missing data should improve internal validity. Using principles derived from decision theory, we also discuss the problem of setting the cutoff prediction score for taking action.

    To change or not to change - translating and culturally adapting the paediatric version of the Moral Distress Scale-Revised (MDS-R)2017In: BMC Medical Ethics, ISSN 1472-6939, E-ISSN 1472-6939, Vol. 18, no 14, 1-9 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Paediatric cancer care poses ethically difficult situations that can lead to value conflicts about what is best for the child, possibly resulting in moral distress. Research on moral distress is lacking in paediatric cancer care in Sweden and most questionnaires are developed in English. The Moral Distress Scale-Revised (MDS-R) is a questionnaire that measures moral distress in specific situations; respondents are asked to indicate both the frequency and the level of disturbance when the situation arises. The aims of this study were to translate and culturally adapt the questionnaire to the context of Swedish paediatric cancer care. In doing so we endeavoured to keep the content in the Swedish version as equivalent to the original as possible but to introduce modifications that improve the functional level and increase respondent satisfaction.

    METHODS: The procedure included linguistic translation and cultural adaptation of MDS-R's paediatric versions for Physicians, Nurses and Other Healthcare Providers to the context of Swedish paediatric cancer care. The process of adjustment included: preparation, translation procedure and respondent validation. The latter included focus group and cognitive interviews with healthcare professionals in paediatric cancer care.

    RESULTS: To achieve a Swedish version with a good functional level and high trustworthiness, some adjustments were made concerning design, language, cultural matters and content. Cognitive interviews revealed problems with stating the level of disturbance hypothetically and items with negations caused even more problems, after having stated that the situation never happens.

    CONCLUSIONS: Translation and cultural adaptation require the involvement of various types of specialist. It is difficult to combine the intention to keep the content as equivalent to the original as possible with the need for modifications that improve the functional level and increase respondent satisfaction. The translated and culturally adapted Swedish MDS-R seems to have equivalent content as well as improved functional level and respondent satisfaction. The adjustments were made to fit paediatric cancer care but it could be argued that the changes are relevant for most areas of paediatric care of seriously ill patients.

    A Randomized Study of the Effects of Additional Fruit and Nuts Consumption on Hepatic Fat Content, Cardiovascular Risk Factors and Basal Metabolic Rate2016In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 11, no 1, e0147149- p.Article in journal (Refereed)
    Abstract [en]

    Background

    Fruit has since long been advocated as a healthy source of many nutrients, however, the high content of sugars in fruit might be a concern.

    Objectives

    To study effects of an increased fruit intake compared with similar amount of extra calories from nuts in humans.

    Methods

    Thirty healthy non-obese participants were randomized to either supplement the diet with fruits or nuts, each at +7 kcal/kg bodyweight/day for two months. Major endpoints were change of hepatic fat content (HFC, by magnetic resonance imaging, MRI), basal metabolic rate (BMR, with indirect calorimetry) and cardiovascular risk markers.

    Results

    Weight gain was numerically similar in both groups although only statistically significant in the group randomized to nuts (fruit: from 22.15±1.61 kg/m2 to 22.30±1.7 kg/m2, p = 0.24 nuts: from 22.54±2.26 kg/m2 to 22.73±2.28 kg/m2, p = 0.045). On the other hand BMR increased in the nut group only (p = 0.028). Only the nut group reported a net increase of calories (from 2519±721 kcal/day to 2763±595 kcal/day, p = 0.035) according to 3-day food registrations. Despite an almost three-fold reported increased fructose-intake in the fruit group (from 9.1±6.0 gram/day to 25.6±9.6 gram/day, p<0.0001, nuts: from 12.4±5.7 gram/day to 6.5±5.3 gram/day, p = 0.007) there was no change of HFC. The numerical increase in fasting insulin was statistical significant only in the fruit group (from 7.73±3.1 pmol/l to 8.81±2.9 pmol/l, p = 0.018, nuts: from 7.29±2.9 pmol/l to 8.62±3.0 pmol/l, p = 0.14). Levels of vitamin C increased in both groups while α-tocopherol/cholesterol-ratio increased only in the fruit group.

    Conclusions

    Although BMR increased in the nut-group only this was not linked with differences in weight gain between groups which potentially could be explained by the lack of reported net caloric increase in the fruit group. In healthy non-obese individuals an increased fruit intake seems safe from cardiovascular risk perspective, including measurement of HFC by MRI.

    Managing reversal of direct oral anticoagulants in emergency situations Anticoagulation Education Task Force White Paper2016In: Thrombosis and Haemostasis, ISSN 0340-6245, Vol. 116, no 6, 1003-1010 p.Article in journal (Refereed)
    Abstract [en]

    Anticoagulation is the cornerstone of prevention and treatment of venous thromboembolism (VTE) and stroke prevention in patients with atrial fibrillation (AF). However, the mechanisms by which anticoagulants confer therapeutic benefit also increase the risk of bleeding. As such, reversal strategies are critical. Until recently, the direct oral anticoagulants (DOACs) dabigatran, rivaroxaban, apixaban, and edoxaban lacked a specific reversal agent. This report is based on findings from the Anticoagulation Education Task Force, which brought together patient groups and professionals representing different medical specialties with an interest in patient safety and expertise in AF, VTE, stroke, anticoagulation, and reversal agents, to discuss the current status of anticoagulation reversal and fundamental changes in management of bleeding associated with DOACs occasioned by the approval of idarucizumab, a specific reversal agent for dabigatran, as well as recent clinical data on specific reversal agents for factor Xa inhibitors. Recommendations are given for when there is a definite need for a reversal agent (e.g. in cases of life-threatening bleeding, bleeding into a closed space or organ, persistent bleeding despite local haemostatic measures, and need for urgent interventions and/or interventions that carry a high risk for bleeding), when reversal agents may be helpful, and when a reversal agent is generally not needed. Key stakeholders who require 24-7/around-the-clock access to these agents vary among hospitals; however, from a practical perspective the emergency department is recommended as an appropriate location for these agents. Clearly, the advent of new agents requires standardised protocols for treating bleeding on an institutional level.

    A Biopsychosocial and Long Term Perspective on Child Behavioral Problems: Impact of Risk and Resilience2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Mental health has become a prominent issue in society. Yet, much remains unknown about the etiology of psychiatric disorders. The aim of the present thesis was to investigate the association between biological, psychological and social factors of risk and resilience and behavioral problems in a birth cohort of Swedish children. 1723 mothers and their children were followed from birth to the age of 12 as part of the South East Sweden Birth Cohort Study (the SESBiC study). Information was gathered through register data, standardized questionnaires and DNA samples.

    In study I, stability of maternal symptoms of depression and the impact on child behavior at age 12 were investigated. The prevalence of depressive symptoms was found to be 12.0 % postpartum. Symptoms of postpartum depression significantly increased the risk for subsequent depressive symptoms 12 years later in women. Children whose mothers reported concurrent symptoms of depression and anxiety had an increased risk for both internalizing and externalizing problems at age 12, but no long term effect on child behavior was seen for postpartum depressive symptoms. The greatest risk was seen for children whose mothers reported symptoms of depression on both occasions. In study II, the impact of gene-environment interaction of 5-HTTLPR and BDNF Val66Met and experience of life events together with symptoms of maternal depression and anxiety on child behavior at age 12 was studied. A main effect of 5-HTTLPR was noticed, but no geneenvironment effects were shown. Similarly to study I, concurrent symptoms of maternal depression and anxiety were an important predictor of child behavioral problems. A high degree of psychosocial stress around childbirth was found to have long lasting detrimental effects on child behavior, increasing the risk for internalizing problems at age 12. Study III investigated the impact of geneenvironment interactions of 5-HTTLPR and BDNF Val66Met and life events together with symptoms of maternal depression and birth characteristics on behavioral problems at age 3. Symptoms of postpartum depression were found to predict internalizing as well as externalizing problems in children three years later. Child experience of life events was a stable predictor of behavioral problems across the scales similar to sociodemographic factors such as parental immigration status and unemployment. No gene-environment interaction effects of 5-HTTLPR or BDNF Val66Met were shown. Study IV used the risk factors identified in studies I-III to investigate factors of resilience to behavioral problems at age 12. The l/l genotype of 5-HTTLPR was associated with a lower risk for behavioral problems at age 12, especially for children facing low adversity. Good social functioning was found to be a general resource factor, independent of the level of risk, while an easy temperament was associated with resilience for children with a high degree of adversity. However, effect sizes were small.

    In summary, the results from the present thesis emphasize the importance of maternal mental health and sociodemographic factors for child mental health at ages 3 and 12, which must be taken into account in clinical settings. Moreover, it adds to the null-findings of the gene-environment effect of 5-HTTLPR and BDNF Val66Met on behavioral problems in children, but indicates a main effect of 5-HTTLPR on internalizing symptoms at age 12.

    2013 (English)In: Maternal and Child Health Journal, ISSN 1092-7875, E-ISSN 1573-6628, Vol. 17, no 3, 405-414 p.Article in journal (Refereed) Published
    Abstract [en]

    Children of depressed mothers have been shown to express behaviour problems to a greater extent than children of non-depressed mothers. The purpose of this study was to examine the persistence of depressive symptoms in mothers and to evaluate the relative importance of symptoms of postpartum depression (PPD) and concurrent maternal symptoms of depression, on child behaviour at age 12. A birth cohort of 1,707 children and their mothers was followed from 3 months after birth to 12 years after birth. Self-reported symptoms of depression in mothers were assessed at baseline and 12-year follow-up where 893 mothers (52.3 %) and their children participated. The mothers reports on the behaviour of their children at age 12 were used. Multivariate analysis was used to assess factors that increased the risk of child behaviour problems. At baseline, 10.4 % scored above the cutoff for symptoms of postpartum depression. At follow up, 18.2 % scored above the cutoff for depressive symptoms. Multivariate analysis showed that ongoing maternal symptoms of depression, as distinct from PPD-symptoms, was the strongest predictor of child behaviour problems at age 12. The gender of the child and socio-demographic factors at baseline were additional factors that affected the risk of behaviour problems in the 12 year old children. Children of mothers who reported symptoms of depression, both postpartum and at follow-up, were at a greater risk of behaviour problems compared to children of women with no depressive symptoms on either occasion. Our findings indicate that recurrent and ongoing maternal depressive symptoms significantly increase the risk of child behaviour problems as reported by mothers, while symptoms of PPD do not seem to result in an increased risk of behaviour problems in 12 year olds. High maternal socio-demographic life stress at childbirth constitutes an important risk factor for later child behaviour problems.

    2013 (English)In: Child and Adolescent Psychiatry and Mental Health, ISSN 1753-2000, E-ISSN 1753-2000, Vol. 7, no 1, 10- p.Article in journal (Refereed) Published
    Abstract [en]

    BACKGROUND: Depression is a common and disabling condition with a high relapse frequency. Maternal mental health problems and experience of traumatic life events are known to increase the risk of behavior problems in children. Recently, genetic factors, in particular gene-by-environment interaction models, have been implicated to explain depressive etiology. However, results are inconclusive.

    METHODS: Study participants were members of the SESBiC-study. A total of 889 mothers and their children were followed during the child's age of 3 months to 12 years. Information on maternal depressive symptoms was gathered postpartum and at a 12 year follow-up. Mothers reported on child behavior and traumatic life events experienced by the child at age 12. Saliva samples were obtained from children for analysis of 5-HTTLPR and BDNF Val66Met polymorphisms.

    RESULTS: Multivariate analysis showed a significant association between maternal symptoms of depression and anxiety, and internalizing problems in 12-year-old children (OR 5.72, 95% CI 3.30-9.91). Furthermore, carriers of two short alleles (s/s) of the 5-HTTLPR showed a more than 4-fold increased risk of internalizing problems at age 12 compared to l/l carriers (OR 4.73, 95% CI 2.14-10.48). No gene-by-environment interaction was found and neither depressive symptoms postpartum or traumatic experiences during childhood stayed significant in the final model.

    CONCLUSIONS: Concurrent maternal symptoms of depression and anxiety are significant risk factors for behavior problems in children, which need to be taken into account in clinical practice. Furthermore, we found a main effect of 5-HTTLPR on internalizing symptoms in 12-year-old children, a finding that needs to be confirmed in future studies.

    Abstract [en]

    Background: The early environment is important for child development and wellbeing. Gene-by-environment studies investigating the impact of the serotonin transporter genelinked polymorphic region (5-HTTLPR) and the Brain Derived Neurotrophic Factor (BDNF) Val66Met polymorphisms by life events on mental health and behaviour problems have been inconclusive. Methodological differences regarding sample sizes, study population, definitions of adversities and measures of mental health problems obstacle their comparability. Furthermore, very few studies included children. The aim of this study was to examine the associations between a broad range of risk factors covering pregnancy and birth, genetic polymorphism, experience of multiple life events and psychosocial environment, and child behaviour at age three, using a comparably large, representative, population-based sample.

    Methods: A total of 1,106 children, and their mothers, were followed from pregnancy to age three. Information on pregnancy and birth-related factors was retrieved from the Medical Birth Register. Questionnaires on depressive symptoms, child behaviour and child experiences of life events were filled in by the mothers. Child saliva samples were used for genotyping the 5-HTTLPR and BDNF Val66Met polymorphisms. Multiple logistic regression was used to investigate the association between psychological scales and genetic polymorphisms.

    Results: Symptoms of postpartum depression increased the risk of both internalizing and externalizing problems. Experience of multiple life events was also a predictor of behavioural problems across the scales. No gene-by-environment or gene-bygene-by-environment interactions were found. Children of immigrants had an increased risk of internalizing problems and parental unemployment was significantly associated with both internalizing and externalizing type of problems.

    Conclusion: This study shows the importance of the psychosocial environment for psychosocial health in preschool children, and adds to  the literature of null-findings of gene-by-environment effects of 5-HTTLPR and BDNF in children

    Abstract [en]

    An increasing prevalence of mental health problems calls for more knowledge into factors associated with resilience in the context of child behavior. Biological factors are seldom considered in psychosocial models of resilience. The present study used multiple statistical methodologies to examine a biopsychosocial model of risk and resilience on behavior at preadolescence. Data from 889 children and their mothers were used. A cumulative adversity score was created by combining maternal symptoms of depression, psychosocial risk and children’s experiences of life events. The proposed resilience factors investigated were candidate genetic polymorphisms, child temperament and social functioning, and maternal sense of coherence. Results show that the l/l genotype of the serotonin transporter linked polymorphic region (5-HTTLPR) was associated with lower internalizing scores, especially for children exposed to low adversity. An easy temperament was associated with resilient outcomes for children exposed to high adversity. Child social functioning was found to be more of a general resource variable buffering risk in both high and low adversity groups. The results support a multiple level model of resilience indicating effects, though small, of both biological and psychosocial factors. The present findings call for both preventive actions and further studies on biopsychosocial models in resilience research.

    A Biopsychosocial Approach to Risk and Resilience on Behavior in Children Followed from Birth to Age 122017In: Child Psychiatry and Human Development, ISSN 0009-398X, E-ISSN 1573-3327, Vol. 48, no 4, 584-596 p.Article in journal (Refereed)
    Abstract [en]

    An increasing prevalence of mental health problems calls for more knowledge into factors associated with resilience. The present study used multiple statistical methodologies to examine a biopsychosocial model of risk and resilience on preadolescence behavior. Data from 889 children and mothers from a birth cohort were used. An adversity score was created by combining maternal symptoms of depression, psychosocial risk and childrens experiences of life events. The proposed resilience factors investigated were candidate genetic polymorphisms, child temperament, social functioning, and maternal sense of coherence. The l/ l genotype of the serotonin transporter linked polymorphic region was associated with lower internalizing scores, but not mainly related to the level of adversity. An easy temperament was associated with resilience for children exposed to high adversity. Social functioning was found to be promotive independent of the risk level. The results support a multiple-level model of resilience indicating effects, though small, of both biological and psychosocial factors.

    Early predictors of behavioural problems in pre-schoolers: a longitudinal study of constitutional and environmental main and interaction effects2016In: BMC Pediatrics, ISSN 1471-2431, E-ISSN 1471-2431, Vol. 16Article in journal (Refereed)
    Abstract [en]

    Background: The early environment is important for child development and wellbeing. Gene-by-environment studies investigating the impact of the serotonin transporter genelinked polymorphic region (5-HTTLPR) and the Brain Derived Neurotrophic Factor (BDNF) Val66Met polymorphisms by life events on mental health and behaviour problems have been inconclusive. Methodological differences regarding sample sizes, study population, definitions of adversities and measures of mental health problems obstacle their comparability. Furthermore, very few studies included children. The aim of this study was to examine the associations between a broad range of risk factors covering pregnancy and birth, genetic polymorphism, experience of multiple life events and psychosocial environment, and child behaviour at age three, using a comparably large, representative, population-based sample.

    Methods: A total of 1,106 children, and their mothers, were followed from pregnancy to age three. Information on pregnancy and birth-related factors was retrieved from the Medical Birth Register. Questionnaires on depressive symptoms, child behaviour and child experiences of life events were filled in by the mothers. Child saliva samples were used for genotyping the 5-HTTLPR and BDNF Val66Met polymorphisms. Multiple logistic regression was used to investigate the association between psychological scales and genetic polymorphisms.

    Results: Symptoms of postpartum depression increased the risk of both internalizing and externalizing problems. Experience of multiple life events was also a predictor of behavioural problems across the scales. No gene-by-environment or gene-bygene-by-environment interactions were found. Children of immigrants had an increased risk of internalizing problems and parental unemployment was significantly associated with both internalizing and externalizing type of problems.

    Conclusion: This study shows the importance of the psychosocial environment for psychosocial health in preschool children, and adds to  the literature of null-findings of gene-by-environment effects of 5-HTTLPR and BDNF in children

    FACTORS ASSOCIATED WITH WORK ABILITY IN PATIENTS WITH CHRONIC WHIPLASH-ASSOCIATED DISORDER GRADE II-III: A CROSS-SECTIONAL ANALYSIS2015In: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 47, no 6, 546-551 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To investigate the factors related to self-perceived work ability in patients with chronic whiplash-associated disorder grades II-III. Design: Cross-sectional analysis. Patients: A total of 166 working age patients with chronic whiplash-associated disorder. Methods: A comprehensive survey collected data on work ability (using the Work Ability Index); demographic, psychosocial, personal, work- and condition-related factors. Forward, stepwise regression modelling was used to assess the factors related to work ability. Results: The proportion of patients in each work ability category were as follows: poor (12.7%); moderate (39.8%); good (38.5%); excellent (9%). Seven factors explained 65% (adjusted R-2 = 0.65, p less than 0.01) of the variance in work ability. In descending order of strength of association, these factors are: greater neck disability due to pain; reduced self-rated health status and health-related quality of life; increased frequency of concentration problems; poor workplace satisfaction; lower self-efficacy for performing daily tasks; and greater work-related stress. Conclusion: Condition-specific and psychosocial factors are associated with self-perceived work ability of individuals with chronic whiplash-associated disorder.

    Magnetic Resonance Imaging of the Heart: Image quality, measurement accuracy and patient experience2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Non-invasive diagnostic imaging of atherosclerotic coronary artery disease (CAD) is frequently carried out with cardiovascular magnetic resonance imaging (CMR) or myocardial perfusion single photon emission computed tomography (MPS). CMR is the gold standard for the evaluation of scar after myocardial infarction and MPS the clinical gold standard for ischemia. Magnetic Resonance Imaging (MRI) is at times difficult for patients and may induce anxiety while patient experience of MPS is largely unknown.

    Aims: To evaluate image quality in CMR with respect to the sequences employed, the influence of atrial fibrillation, myocardial perfusion and the impact of patient information. Further, to study patient experience in relation to MRI with the goal of improving the care of these patients.

    Method: Four study designs have been used. In paper I, experimental cross-over, paper (II) experimental controlled clinical trial, paper (III) psychometric crosssectional study and paper (IV) prospective intervention study. A total of 475 patients ≥ 18 years with primarily cardiac problems (I-IV) except for those referred for MRI of the spine (III) were included in the four studies.

    Result: In patients (n=20) with atrial fibrillation, a single shot steady state free precession (SS-SSFP) sequence showed significantly better image quality than the standard segmented inversion recovery fast gradient echo (IR-FGRE) sequence (I). In first-pass perfusion imaging the gradient echo-echo planar imaging sequence (GREEPI) (n=30) had lower signal-to-noise and contrast–to-noise ratios than the steady state free precession sequence (SSFP) (n=30) but displayed a higher correlation with the MPS results, evaluated both qualitatively and quantitatively (II). The MRIAnxiety Questionnaire (MRI-AQ) was validated on patients, referred for MRI of either the spine (n=193) or the heart (n=54). The final instrument had 15 items divided in two factors regarding Anxiety and Relaxation. The instrument was found to have satisfactory psychometric properties (III). Patients who prior CMR viewed an information video scored significantly (lower) better in the factor Relaxation, than those who received standard information. Patients who underwent MPS scored lower on both factors, Anxiety and Relaxation. The extra video information had no effect on CMR image quality (IV).

    Conclusion: Single shot imaging in atrial fibrillation produced images with less artefact than a segmented sequence. In first-pass perfusion imaging, the sequence GRE-EPI was superior to SSFP. A questionnaire depicting anxiety during MRI showed that video information prior to imaging helped patients relax but did not result in an improvement in image quality.

    Abstract [en]

    Pandgt;Background: Magnetic resonance imaging (MRI) of the heart generally requires breath holding and a regular rhythm. Single shot 2D steady-state free precession (SS_SSFP) is a fast sequence insensitive to arrhythmia as well as breath holding. Our purpose was to determine image quality, signal-to-noise (SNR) and contrast-to-noise (CNR) ratios and infarct size with a fast single shot and a standard segmented MRI sequence in patients with permanent atrial fibrillation and chronic myocardial infarction. Methods: Twenty patients with chronic myocardial infarction and ongoing atrial fibrillation were examined with inversion recovery SS_SSFP and segmented inversion recovery 2D fast gradient echo (IR_FGRE). Image quality was assessed in four categories: delineation of infarcted and non-infarcted myocardium, occurrence of artefacts and overall image quality. SNR and CNR were calculated. Myocardial volume (ml) and infarct size, expressed as volume (ml) and extent (%), were calculated, and the methodological error was assessed. Results: SS_SSFP had significantly better quality scores in all categories (P = 0 center dot 037, P = 0 center dot 014, P = 0 center dot 021, P = 0 center dot 03). SNRinfarct and SNRblood were significantly better for IR_FGRE than for SS_SSFP (P = 0 center dot 048, P = 0 center dot 018). No significant difference was found in SNRmyocardium and CNR. The myocardial volume was significantly larger with SS_SSFP (170 center dot 7 versus 159 center dot 2 ml, P andlt; 0 center dot 001), but no significant difference was found in infarct volume and infarct extent. Conclusion: SS_SSFP displayed significantly better image quality than IR_FGRE. The infarct size and the error in its determination were equal for both sequences, and the examination time was shorter with SS_SSFP.

    Abstract [en]

    Background To assess myocardial perfusion, steady-state free precession cardiac magnetic resonance (SSFP, CMR) was compared with gradient-echo–echo-planar imaging (GRE-EPI) using myocardial perfusion scintigraphy (MPS) as reference. Methods Cardiac magnetic resonance perfusion was recorded in 30 patients with SSFP and in another 30 patients with GRE-EPI. Timing and extent of inflow delay to the myocardium was visually assessed. Signal-to-noise (SNR) and contrast-to-noise (CNR) ratios were calculated. Myocardial scar was visualized with a phase-sensitive inversion recovery sequence (PSIR). All scar positive segments were considered pathologic. In MPS, stress and rest images were used as in clinical reporting. The CMR contrast wash-in slope was calculated and compared with the stress score from the MPS examination. CMR scar, CMR perfusion and MPS were assessed separately by one expert for each method who was blinded to other aspects of the study. Results Visual assessment of CMR had a sensitivity for the detection of an abnormal MPS at 78% (SSFP) versus 91% (GRE-EPI) and a specificity of 58% (SSFP) versus 84% (GRE-EPI). Kappa statistics for SSFP and MPS was 0·29, for GRE-EPI and MPS 0·72. The ANOVA of CMR perfusion slopes for all segments versus MPS score (four levels based on MPS) had correlation r = 0·64 (SSFP) and r = 0·96 (GRE-EPI). SNR was for normal segments 35·63 ± 11·80 (SSFP) and 17·98 ± 8·31 (GRE-EPI), while CNR was 28·79 ± 10·43 (SSFP) and 13·06 ± 7·61 (GRE-EPI). Conclusion GRE-EPI displayed higher agreement with the MPS results than SSFP despite significantly lower signal intensity, SNR and CNR.

    Aim. To develop and validate a new instrument measuring patient anxiety during Magnetic Resonance Imaging examinations, Magnetic Resonance Imaging-Anxiety Questionnaire. Background. Questionnaires measuring patients anxiety during Magnetic Resonance Imaging examinations have been the same as used in a wide range of conditions. To learn about patients experience during examination and to evaluate interventions, a specific questionnaire measuring patient anxiety during Magnetic Resonance Imaging is needed. Design. Psychometric cross-sectional study with test-retest design. Methods. A new questionnaire, Magnetic Resonance Imaging-Anxiety Questionnaire, was designed from patient expressions of anxiety in Magnetic Resonance Imaging-scanners. The sample was recruited between October 2012-October 2014. Factor structure was evaluated with exploratory factor analysis and internal consistency with Cronbachs alpha. Criterion-related validity, known-group validity and test-retest was calculated. Results. Patients referred for Magnetic Resonance Imaging of either the spine or the heart, were invited to participate. The development and validation of Magnetic Resonance Imaging-Anxiety Questionnaire resulted in 15 items consisting of two factors. Cronbachs alpha was found to be high. Magnetic Resonance Imaging-Anxiety Questionnaire correlated higher with instruments measuring anxiety than with depression scales. Known-group validity demonstrated a higher level of anxiety for patients undergoing Magnetic Resonance Imaging scan of the heart than for those examining the spine. Test-retest reliability demonstrated acceptable level for the scale. Conclusion. Magnetic Resonance Imaging-Anxiety Questionnaire bridges a gap among existing questionnaires, making it a simple and useful tool for measuring patient anxiety during Magnetic Resonance Imaging examinations.

    Moving forward in life after being an on-looker in intensive care partner's experience of group-communication2016Conference paper (Refereed)
    Abstract [en]

    Background: Partners have a burdensome time during and after their partners’ intensive care period. They may appear to be coping well

    outwardly but inside feel vulnerable and lost. Evaluated interventions for partners on this aspect are limited.

    Aim: The aim of this study was to describe the experience of participating in group communication with other partners of former intensive

    care patients.

    Design: The study has a descriptive intervention-based design where group communication for partners of former, surviving intensive care

    unit (ICU) patients was evaluated.

    Methods: A strategic selection was made of adult partners to former adult intensive care patients (n=15), 5 men and 10 women, aged

    37–89 years. Two group communication sessions lasting 2 h were held at monthly intervals with three to five partners. The partners later wrote,

    in a notebook, about their feelings of participating in group communications. To deepen the understanding of the impact of the sessions, six of

    the partners were interviewed. Content analysis was used to analyse the notebooks and the interviews.

    Findings: Three categories were identified: (1) Emotional impact, the partners felt togetherness and experienced worries and gratitude, (2)

    Confirmation, consciousness through insight and reflection and (3) The meeting design, group constellation and recommendation to participate

    in group communication.

    Conclusion: Partners of an intensive care patient are on a journey, constantly trying to adapt to the new situation and find new strategies

    to ever-changing circumstances. Group communications contributed to togetherness and confirmation. To share experiences with others is one

    way for partners to be able to move forward in life.

    Relevance to clinical practice: Group communication with other patients’ partners eases the process of going through the burden of

    being a partner to an intensive care patient. Group communications needs to be further developed and evaluated to obtain consensus and

    evidence for the best practice.

    MicroRNAs as circulating biomarkers in acute coronary syndromes: A review2016In: Vascular pharmacology, ISSN 1537-1891, E-ISSN 1879-3649, Vol. 81, 15-21 p.Article, review/survey (Refereed)
    Abstract [en]

    Coronary artery disease (CAD) and its complications remain the most common cause of death worldwide. Cardiac troponins (cTn) are standard biomarkers used today for diagnosis and risk stratification of myocardial infarction (MI). Increasing efforts are made to develop additional, new biomarkers for more effective and safe rule-in and rule-out of MI patients at the emergency department. During the past decade, microRNAs (miRNAs) have emerged as new, potential diagnostic biomarkers in several diseases, including MI. In this review, we aimed to summarize some of the prominent studies in the field, and discuss the potential value of miRNAs in the diagnosis of MI. (C) 2016 Elsevier Inc. All rights reserved.

    Demographics and post-mortem toxicology findings in deaths among people arrested multiple times for use of illicit drugs and/or impaired driving2016In: Forensic Science International, ISSN 0379-0738, E-ISSN 1872-6283, Vol. 265, 138-143 p.Article in journal (Refereed)
    Abstract [en]

    Background: Multiple arrests for use of illicit drugs and/or impaired driving strongly suggests the existence of a personality disorder and/or a substance abuse problem. Methods: This retrospective study (1993-2010) used a national forensic toxicology database (TOXBASE), and we identified 3943 individuals with two or more arrests for use of illicit drugs and/or impaired driving. These individuals had subsequently died from a fatal drug poisoning or some other cause of death, such as trauma. Results: Of the 3943 repeat offenders 1807 (46%) died from a fatal drug overdose and 2136 (54%) died from other causes (p amp;lt; 0.001). The repeat offenders were predominantly male (90% vs 10%) and mean age of drug poisoning deaths was 5 y younger (mean 35 y) than other causes of death (mean 40 y). Significantly more repeat offenders (46%) died from drug overdose compared with all other forensic autopsies (14%) (p amp;lt; 0.001). Four or more drugs were identified in femoral blood in 44% of deaths from poisoning (drug overdose) compared with 18% of deaths by other causes (p amp;lt; 0.001). The manner of death was considered accidental in 54% of deaths among repeat offenders compared with 28% for other suspicious deaths (p amp;lt; 0.001). The psychoactive substances most commonly identified in autopsy blood from repeat offenders were ethanol, morphine (from heroin), diazepam, amphetamines, cannabis, and various opioids. Conclusions: This study shows that people arrested multiple times for use of illicit drugs and/or impaired driving are more likely to die by accidentally overdosing with drugs. Lives might be saved if repeat offenders were sentenced to treatment and rehabilitation for their drug abuse problem instead of conventional penalties for drug-related crimes.

    Pain and activity limitations in women and men with contemporary treated early RA compared to 10 years ago: the Swedish TIRA project2015In: Scandinavian Journal of Rheumatology, ISSN 0300-9742, E-ISSN 1502-7732, Vol. 44, no 4, 259-264 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: To study differences regarding pain and activity limitations during the 3 years following diagnosis in women and men with contemporary treated early RA compared with their counterparts who were diagnosed 10 years earlier. Method: This study was based on patients recruited to the Early Intervention in RA (TIRA) project. In the first cohort (TIRA-1) 320 patients were included in time for diagnosis during 1996-1998 and 463 patients were included in the second cohort (TIRA-2) during 2006-2009. Disease activity, pain intensity (Visual Analogue Scale, VAS), bodily pain (BP) in the 36-item Short Form Health Survey (SF-36), activity limitations (Health Assessment Questionnaire, HAQ), and medication were reported at inclusion and at follow-up after 1, 2, and 3 years. Results: Disease activity, pain, and activity limitations were pronounced at inclusion across both genders and in both cohorts, with some improvement observed during the first year after diagnosis. Disease activity did not differ between cohorts at inclusion but was significantly lower at the follow-ups in the TIRA-2 cohort, in which the patients were prescribed traditional disease-modifying anti-rheumatic drugs (DMARDs) and biological agents more frequently. In TIRA-2, patients reported significantly lower pain and activity limitations at all follow-ups, with men reporting lower pain than women. Women reported significantly higher activity limitations at all time points in TIRA-2. Conclusions: Pain and activity limitations were still pronounced in the contemporary treated early RA cohort compared with their counterparts diagnosed 10 years earlier and both of these factors need to be addressed in clinical settings.

    Pain and difficulties performing valued life activities in women and men with rheumatoid arthritis2015In: Clinical Rheumatology, ISSN 0770-3198, E-ISSN 1434-9949, Vol. 34, no 8, 1353-1362 p.Article in journal (Refereed)
    Abstract [en]

    This study aimed to examine the difficulties with performing valued life activities in relation to pain intensity in women and men with rheumatoid arthritis (RA). In total, 737 persons with RA (73 % women) from three rheumatology units in Sweden responded to a questionnaire measuring performance of 33 valued life activities and self-rated pain. The relationships between performance of valued life activities (VLAs) and pain (measured by visual analogue scale (VAS)) were analysed based on gender. Multiple linear regression analyses were conducted with the total VLA score as dependent variable. Women reported more pain and difficulties in performing valued life activities than men. Across genders, 85 % reported at least one valued life activity affected by RA. Significantly more women than men encountered difficulties in performing some activities such as cooking, gardening and meeting new people. Women reported higher pain intensity (35 mm) than men (31 mm). Almost all 33 difficulty ratings for valued life activities were higher among persons with high pain (greater than 40 mm) than persons with lower pain. Difficulty ratings for valued life activities correlated positively with pain in persons with lower pain, but not among those with high pain. The results highlight the importance of addressing pain, especially among women with RA, as they reported pain to impact on their valued life activities. Interestingly, this was evident also in women with lower levels of pain.

    Self-efficacy and pain acceptance as mediators of the relationship between pain and performance of valued life activities in women and men with rheumatoid arthritis2017In: Clinical Rehabilitation, ISSN 0269-2155, E-ISSN 1477-0873, Vol. 31, no 6, 824-834 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To study whether personal factors (self-efficacy and pain acceptance) mediate the relationship between pain and performance of valued life activities in persons with rheumatoid arthritis.

    METHODS: Persons with rheumatoid arthritis for at least four years (n = 737; 73% women) answered a questionnaire measuring self-efficacy, pain acceptance, performance of valued life activities, and self-rated pain. Relationships among these constructs were explored using univariate and multivariate analyses. Structural equation modelling was then used to examine the mediational role of personal factors on the relationship between pain and performance of valued life activities.

    RESULTS: A direct negative association between pain and performance of valued life activities was identified (Beta = .34, P < .001). This suggests that people with rheumatoid arthritis who had higher levels of pain has increased difficulties in performing valued life activities. Self-efficacy and activity engagement component of pain acceptance mediated the relationship between pain and performance of valued life activities, however the pain willingness component of pain acceptance did not influence participation in valued life activities.

    CONCLUSION: These findings highlight the importance of considering personal factors, such as pain acceptance and self-efficacy, in facilitating participation in valued life activities.

    Ett praktiskt försök: nationell prioriteringsmodell tillämpad i Landstinget i Kalmar Län2008Report (Other academic)
    Abstract [sv]

    Idag finns en nationell modell för hur öppna vertikala prioriteringar kan genomföras. Den är resultatet av de samlade erfarenheterna av att omsätta riksdagens riktlinjer för prioriteringar i praktiskt prioriteringsarbete. Modellen är framtagen av Socialstyrelsen, PrioriteringsCentrum samt flera vårdförbund och landsting gemensamt. Också FSA och LSR har ställt sig bakom den. Fram tills nu har det dock saknats praktisk erfarenhet av att tillämpa modellen inom arbetsterapi och sjukgymnastik. Men sedan drygt två år tillbaka har de båda rehabiliteringsenheterna Samrehab och Rehab Söder i Landstinget i Kalmar län med stöd av PrioriteringsCentrum bedrivit ett prioriteringsarbete i enlighet med modellen. Det är deras erfarenheter denna rapport handlar om.

    Prioriteringsarbetet har med nära stöd av verksamhetsledningarna letts av en projektgrupp bestående av arbetsterapeuter och sjukgymnaster från de båda enheterna som fungerat som handledare, ansvarat för metodutveckling och utbildning samt kontinuerligt utvärderat arbetet. Själva tillämpningen av den nationella modellen har ett antal utvecklingsgrupper inom olika specialistområden stått för. De har valt ut och rangordnat tillstånd och olika åtgärder som de ansett angelägna att ta fram prioriteringar för.

    Ett av syftena med prioriteringsarbetet i Samrehab och Rehab Söder var att få till stånd länsövergripande prioriteringar inom vissa verksamheter och/eller för vissa sjukdomstillstånd för en mer likvärdig vård. Idag finns elva sådana prioriteringsordningar presenterade på landstingets intranät och ytterligare ett tiotal är under bearbetning. Utöver vinsterna med det förbättrade samarbetet mellan länsdelarna har alltså den interna öppenheten i prioriteringarna ökat. Alla anställda kan lätt få fram prioriteringsordningarna via basenheternas hemsidor när man behöver det. Andra vinster av prioriteringsarbetet är att kännedomen och kunskapen om riksdagens riktlinjer för prioriteringar har ökat, att en större del av basenheternas verksamhet idag är faktabaserad än innan prioriteringsarbetet startade samt att den kliniska erfarenheten har tillvaratagits och dokumenterats på ett mer systematiskt sätt än tidigare. Det har dessutom skett en utveckling av den nationella modellen som har blivit mer konkret vad det gäller svårighetsgrad och nytta. En majoritet av deltagarna i utvecklingsgrupperna har haft en positiv inställning till att arbeta med prioriteringar utifrån modellen och upplever också att de erhållit ett språk som gör det möjligt att kommunicera prioriteringar med politiker och landstingsledning.

    I rapporten presenteras också de frågor kring modellens olika steg som dykt upp under arbetets gång. Tre frågor har dominerat; syftet med prioriteringsarbetet, tolkningen av modellen samt dokumentationen av prioriteringsarbetet.

     

    Syftet har inte alltid upplevts som helt klart och sambandet mellan prioriteringsarbetet och annat kvalitetsarbete som t ex framtagande av behandlingsriktlinjer har varit otydligt. När det gäller tolkningen av modellen har t ex graderingen av svårighetsgrad och patientnytta gett upphov till frustration. Också den skriftliga presentationen av prioriteringsordningarna har stundtals upplevts som krånglig och svår att förmedla till övriga medarbetare på ett användbart sätt.

    Alla de åtgärder som projektgruppen vidtagit för att underlätta de svårigheter som dykt upp delar de här med sig av i rapporten. Likaså pekar de ut viktiga förutsättningar för ett prioriteringsarbete (som t ex tid, kompetens, kontinuitet och legitima deltagare). Syftet med att pröva om den nationella modellen för öppna vertikala prioriteringar är användbar i Samrehabs och Rehab Söders prioriteringsarbete är uppnådd och det har inte framkommit något som ger anledning att ifrågasätta modellens grundstruktur. Förslag har dock givits bl a avseende bedömning av svårighetsgrad och patientnytta för att ytterligare underlätta tillämpningen.

    Nu planerar enheterna att gå vidare med sitt prioriteringsarbete, dels genom att fortsätta att ta fram behandlingsriktlinjer som kombineras med prioriteringar men också genom att ytterligare utveckla prioriteringsstödet för de enskilda medarbetarna i deras dagliga patientarbete. Om andra verksamheter i Sverige  följer efter detta exempel från Kalmar län med att öppet redovisa hur de hanterar prioriteringar i sin verksamhet kommer ytterligare nya erfarenheter att hjälpa metodutvecklingen på traven.

    Self-perceived oral health among 19-year-olds in a Swedish County - A comparative study between 2004 and 20112016In: Swedish Dental Journal, ISSN 0347-9994, Vol. 40, no 1, 53-65 p.Article in journal (Refereed)
    Abstract [en]

    For decades, Swedish dental professionals have collected clinical epidemiological data from the dental records. To supplement the epidemiology, Ostergotland County Council decided to examine patient perceptions of oral health: self-rated knowledge, self-perceived oral health, and opinions about oral health. The aim was to compare self-perceived oral health among 19-year-olds to determine differences between genders, various municipalities and between 2004 and 2011. This study analysed the responses from two cross-sectional surveys of the entire population of 19-year-olds in Ostergotland County, Sweden, performed in 2004 and 2011. Of the 2,413 (53 %) (50 % men, 50 % women) 19-year-olds who responded to the questionnaire in 2004 and the 3,803 (67 %) (50 % men, 50 % women) in 2011, most 19-year-olds (88.1 % [2004] and 87.5 % [am]) reported satisfaction with their oral health. Around half of the respondents rated their knowledge on periodontitis as low. Boys rated their knowledge about avoiding periodontitis higher than girls (p&lt;0.05 in 2004 and p&lt;0.001 in 2011). In 2004, 84.7 % reported shooting pain. In 2011 that figure was 83.7 %. The respondents expressed some uncertainty about the benefits of fluoride toothpaste (7.5 % in 2004 and 9.3 % in 2011), especially the boys (10.3 % in 2004 and 10.5 % in 2011). Girls reported both a higher social impact and greater concern about aesthetics related to their oral health. They also reported headache (27.5 %) nearly twice as often as boys (14.2 %) (p&gt;0.001). Responses between the municipalities did not differ, with the exception of items regarding periodontitis. Thus, this study found indications that perceptions of oral health and knowledge in Ostergotland County complied with Swedish Dental Act. The study also found patient perceptions of oral health among 19-year-olds to be good.

    Negative Checkpoint Regulatory Molecule 2B4 (CD244) Upregulation Is Associated with Invariant Natural Killer T Cell Alterations and Human Immunodeficiency Virus Disease Progression2017In: Frontiers in Immunology, ISSN 1664-3224, E-ISSN 1664-3224, Vol. 8, 338Article in journal (Refereed)
    Abstract [en]

    The CD1d-restricted invariant natural killer T (iNKT) cells are implicated in innate immune responses against human immunodeficiency virus (HIV). However, the determinants of cellular dysfunction across the iNKT cells subsets are seldom defined in HIV disease. Herein, we provide evidence for the involvement of the negative checkpoint regulator (NCR) 2B4 in iNKT cell alteration in a well-defined cohort of HIV-seropositive anti-retroviral therapy (ART) naive, ART-treated, and elite controllers (ECs). We report on exaggerated 2B4 expression on iNKT cells of HIV-infected treatment-naive individuals. In sharp contrast to CD4-iNKT cells, 2B4 expression was significantly higher on CD4+ iNKT cell subset. Notably, an increased level of 2B4 on iNKT cells was strongly correlated with parameters associated with HIV disease progression. Further, iNKT cells from ARTnaive individuals were defective in their ability to produce intracellular IFN-gamma Together, our results suggest that the levels of 2B4 expression and the downstream co-inhibitory signaling events may contribute to impaired iNKT cell responses.
