    Heart failure in primary care with special emphasis on costs and benefits of a disease management programme2014Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background and aim. Heart failure (HF) is a common condition associated with poor quality of life (QoL), high morbidity and mortality and is frequently occurring in primary health care (PHC). It involves a substantial economic burden on the health care expenditure. There are modern pharmacological treatments with evident impact on QoL, morbidity, mortality, and proved to be cost-effective. Despite this knowledge, the treatment of HF is considered somewhat insufficient. There are several HF management programmes (HFMP) showing beneficial effects but these studies is predominantly based in hospital care (HC).

    The first aim of this thesis was to describe patients with HF in the PHC regarding gender differences, diagnosis, treatment and health related costs (I, II).The second aim was to evaluate whether HFMP have beneficial effects in the PHC regarding cardiac function, quality of life, health care utilization and health care-related costs (III,IV).

    Methods. The initial study involved retrospective collection of data from 256 patients with symptomatic HF in PHC (I). The data collected were gender, age, diagnostics and ongoing treatment. The second study was an economic calculation performed on 115 patients (II). The economic data was retrospectively retrieved as the number of hospital days, visits to nurses and physicians in HC and PHC, prescribed cardiovascular drugs and performed investigation during retrospectively for one year. The third and fourth study was based on a randomized, prospective, open-label study which was subsequently performed (III,IV). The study enrolled 160 patients with systolic HF who were randomized to either an intervention or a control group. The patients in the intervention group retrieved follow-up of HF qualified nurses and physicians in the PHC, involving education about HF and furthermore, optimizing the treatment according to guidelines if possible. The patients in the control group had a followup performed by their regular general practitioner (GP) receiving customary management according to local routines but there was no contact with HF nurses. The primary endpoint of the study was a composite endpoint consisting of changes in survival, hospitalization, heart function and quality of life (QoL) and to compare differences in resource utilization and costs (III,IV).

    Results. In the first study, the prevalence was 2% and the average age was 78 years (I). The most frequent cause of HF was IHD followed o hypertension. The diagnosis in the study population was based on clinical criteria and only 31% had been subjected to echocardiography. The most common treatment was diuretics (84%) and angiotensin converting enzyme inhibitors (ACEI) were used in 56% of patients. In the following prospective study, the intervention group had significant improvements in composite endpoints. There were in the intervention group more patients with reduced levels of NTproBNP (p=0.012) and improved cardiac function (p=0.03). No significant changes were found in New York Heart Association (NYHA) functional class or QoL. The intervention involved less health care contacts (p=0.04), less emergency ward visits (p=0.002) and hospitalizations (p=0.03). The total cost for HC and PHC was EUR 4471 in the intervention group and EUR 6638 in the control group which implies a cost reduction of EUR 2167 (33%).

    Conclusions. HF is common in PHC with a prevalence of 2% the study population had an average age of 78 years. Only 31 % of the HF patients have performed an echocardiographic investigation. Treatment with ACEI occurred in 56 %. Differences were found between genders since women had performed significantly fewer echocardiographic investigations and, had less treatment with ACEI. When implementing HFMP in PHC, beneficial effects were found regarding cardiac function and health care-related costs in patients with systolic HF. These findings indicate that HFMP might be used even in PHC.

    Abstract [en]

    Objective - The aim of the present study was to describe patients considered to have had heart failure (HF), or were being treated for HF, in a defined area in primary health care, e.g. diagnostic procedures, aetiologic diseases and management, and to evaluate whether there is a difference between the genders. Design - Descriptive retrospective investigation. Setting - ┼tvidaberg community situated in southeast Sweden, 12 400 inhabitants. Patients - 256 patients treated for symptomatic HF. Main outcome measures - Prevalence, aetiology, diagnostic procedures and management of HF and differences between the genders. Results - The diagnosis of HF was based on an objective evaluation of cardiac function in only 31% of the patients. Ischaemic heart disease (IHD) was the predominant associated disease, followed by hypertension. Therapy included diuretics (84%), angiotensin converting enzyme (ACE) inhibitors (56%) and digoxin (40%). Only 52% had optimal doses of ACE inhibitors. Women had a significantly higher mean age and their diagnoses were based on an objective diagnostic test (echocardiography) in only 20%. Women were prescribed ACE inhibitors to a lesser extent (43%) than men (64%) and with a lower optimal dose (44% versus 56% in men). Conclusion - There is still room for improvement in the management of HF in primary health care, especially in women, where the diagnosis is not generally based on an objective evaluation of cardiac function and where the treatment to a lesser extent than in men includes ACE inhibitors.

    Abstract [en]

    Objectives. To calculate the cost for patients with heart failure (HF) in a primary healthcare setting. Design. Retrospective study of all available patient data during a period of one year. Setting. Two healthcare centers in Linköping in the southeastern region of Sweden, covering a population of 19 400 inhabitants. Subjects. A total of 115 patients with a diagnosis of HF. Main outcome measures. The healthcare costs for patients with HF and the healthcare utilization concerning hospital days and visits to doctors and nurses in hospital care and primary healthcare. Results. The mean annual cost for a patient with HF was SEK 37 100. There were no significant differences in cost between gender, age, New York Heart Association functional class, and cardiac function. The distribution of cost was 47% for hospital care, 22% for primary healthcare, 18% for medication, 5% for nursing home, and 6% for examinations. Conclusion. Hospital care accounts for the largest cost but the cost in primary healthcare is larger than previously shown. The total annual cost for patients with HF in Sweden is in the range of SEK 5.0–6.7 billion according to this calculation, which is higher than previously known.Read More: http://informahealthcare.com/doi/abs/10.1080/02813430500197647

    Abstract [en]

    Aim: Heart failure (HF) is a common but serious condition which involves a significant economic burden on the health care economy. The purpose of this study was to evaluate cost and quality of life (QoL) implications of implementing a HF management program (HFMP) in primary health care (PHC).

    Methods and results: This was a prospective randomized open-label study including 160 patientswith a diagnosis of HF from five PHC centers in south-eastern Sweden. Patients randomized to the intervention group received information about HF from HF nurses and from a validated computer-based awareness program. HF nurses and physicians followed the patients intensely in order to optimize HF treatment according to current guidelines. The patients in the control group were followed by their regular general practitioner (GP) and received standard treatment according to local management routines. No significant changes were observed in NYHA class and quality-adjusted life years (QALY), implying that functional class and QoL were preserved. However, costs for hospital care (HC) and PHC were reduced by EUR 2167, or 33%. The total cost was EUR 4471 in the intervention group and EUR 6638 in the control group.

    Conclusions: Introducing HFMP in Swedish PHC in patients with HF entails a significant reduction in resource utilization and costs, and maintains QoL. Based on these results, a broader implementation of HFMP in PHC may be recommended. However, results should be confirmed with extended follow-up to verify  long-term effects.

    Thermodynamic Characterization of the Interaction between the C-Terminal Domain of Extracellular Superoxide Dismutase and Heparin by Isothermal Titration Calorimetry2009Ingår i: BIOCHEMISTRY, ISSN 0006-2960, Vol. 48, nr 41, s. 9932-9940Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Extracellular superoxide dismutase (ECSOD) interacts with heparin through its C-terminal domain. In this study we used isothermal titration calorimetry (ITC) to get detailed thermodynamic information about the interaction. We have shown that the interaction between ECSOD and intestinal mucosal heparin (M-w 6000-30000 Da) is exothermic and driven by enthalpy at physiological salt concentration. However, the contribution from entropy is favorable for binding or small isolated heparin fragments. By studying different size-defined heparin fragments, we also concluded that it hexasaccharide moiety is sufficient for strong binding to ECSOD. The binding involves proton transfer from the buffer to the ECSOD-heparin complex, and the results indicate that the number of ionic interactions made between ECSOD and heparin upon binding varies from three to five for heparin and an octasaccharide fragment, respectively. Surprisingly and despite the many charges found oil both the protein and the polysaccharide, our results indicate that the nonionic contribution to the binding is large. From the temperature dependence we have calculated the constant pressure heat capacity change (Delta C-p) of the interaction to -644 J K-1 mol(-1) and -306 J K-1 mol(-1) for heparin and all octasaccharide, respectively

    Coexpression of yeast copper chaperone (yCCS) and CuZn-superoxide dismutases in Escherichia coli yields protein with high copper contents2004Ingår i: Protein Expression and Purification, ISSN 1046-5928, E-ISSN 1096-0279, Vol. 37, nr 2, s. 311-319Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To fully understand the function of the Cu- and Zn-containing superoxide dismutases in normal and disordered cells, it is essential to study protein variants with full metal contents. We describe the use of an Escherichia coli-based expression system for the overproduction of human intracellular wild type CuZn-superoxide dismutase (SOD), the CuZnSOD variant F50E/G51E (monomeric), two amyotrophic lateral sclerosis-related mutant CuZnSOD variants (D90A and G93A), and PseudoEC-SOD, all with high Cu contents. This system is based on coexpression of the SOD variants with the yeast copper chaperone yCCS during growth in a medium supplemented with Cu2+ and Zn2+. The recombinant SOD enzymes were all found in the cytosol and represented 30-50% of the total bacterial protein. The enzymes were purified to homogeneity and active enzymes were obtained in high yield. The resulting proteins were characterized through immunochemical reactivity and specific activity analyses, in conjunction with mass-, photo-, and atomic absorption-spectroscopy. © 2004 Elsevier Inc.

    The lived experience of the early postoperative period after colorectal cancer surgery2011Ingår i: European Journal of Cancer Care, ISSN 0961-5423, E-ISSN 1365-2354, Vol. 20, nr 2, s. 248-256Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Colorectal cancer is one of the most common cancer diagnoses and undergoing colorectal cancer surgery is reported to be associated with physical symptoms and psychological reactions. Social support is described as important during the postoperative period. The purpose of this paper was to describe how patients experience the early postoperative period after colorectal cancer surgery.

    Interviews according a phenomenological approach were performed with 13 adult participants, within 1 week after discharge from hospital. Data were collected from August 2006 to February 2007. Analysis of the interview transcripts was conducted according to Giorgi.

    The essence of the phenomenon was to regain control over ones body in the early postoperative period after colorectal cancer surgery. Lack of control, fear of wound and anastomosis rupture, insecurity according to complications was prominent findings.

    When caring for these patients it is a challenge to be sensitive, encourage and promote patients to express their feelings and needs. One possibility to empower the patients and give support could be a follow up phone call within a week after discharge.

    Abstract [sv]

    Bakgrund: Att arbeta under jourtid inom kommunsjukvården innebär att sjuksköterskan ständigt ställs inför bedömningar av personer med försämrat hälsotillstånd. Bedömningarna sker ofta under tidspress, med otillräcklig bemanning och där stora geografiska områden råder.

    Syfte: Studiens syfte var att beskriva sjuksköterskans upplevelse av att genomföra bedömningar av en persons försämrade hälsotillstånd under jourtid inom kommunsjukvården.

    Metod: Kvalitativ metod med induktiv ansats valdes. Tjugo semistrukturerade intervjuer genomfördes med sjuksköterskor inom kommunsjukvården. En konventionell innehållsanalys inspirerad av Hsieh & Shannon användes för att analysera datamaterialet.

    Resultat: Studien resulterade i ett övergripande tema; olika faktorer påverkar bedömningen. Tre kategorier identifierades; personliga känslor, resurser och kommunikation. Sex sub-kategorier framkom; positiva och negativa känslor, förutsättningar i arbetet, egna förutsättningar, förutsättningar i organisationen och samarbete. Längre erfarenhet hos sjuksköterskan visade att tryggare känslor kring bedömningen upplevdes. Brister sågs gällande gemensamt journalsystem och ibland bristande tillgång till journalsystem. Bristande rapport från omvårdnadspersonal samt att ett behov av ökad personaltäthet fanns.

    Konklusion: Studien belyste vikten av god kommunikation mellan personen vars hälsotillstånd bedöms, omvårdnadspersonal, sjuksköterska, läkare och anhörig. Ett behov sågs av att höja omvårdnadspersonalens kompetens och deras sätt att förmedla information. Det framkom att lättillgängliga journaler och att ett gemensamt journalsystem skulle kunna underlätta bedömningen.

    Magnetic Resonance Imaging of the Heart: Image quality, measurement accuracy and patient experience2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    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.

    Positive effect on patient experience of video-information given prior to cardiovascular magnetic resonance imaging, a clinical trial2018Ingår i: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 27, nr 5-6, s. 1250-1261Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aims: To evaluate the effect of video information given before cardiovascular magnetic resonance imaging on patient anxiety and to compare patient experiences of cardiovascular magnetic resonance imaging versus myocardial perfusion scintigraphy. To evaluate if additional information has an impact on motion artefacts. Background: Cardiovascular magnetic resonance imaging and myocardial perfusion scintigraphy are technically advanced methods for the evaluation of heart diseases. Although cardiovascular magnetic resonance imaging is considered to be painless, patients may experience anxiety due to the closed environment. Design: A prospective randomized intervention study, not registered. Methods: The sample (n=148) consisted of 97 patients referred for cardiovascular magnetic resonance imaging, randomized to receive either video information in addition to standard text-information (CMR-video/n=49) or standard text-information alone (CMR-standard/n=48). A third group undergoing myocardial perfusion scintigraphy (n=51) was compared with the cardiovascular magnetic resonance imaging-standard group. Anxiety was evaluated before, immediately after the procedure and one week later. Five questionnaires were used: Cardiac Anxiety Questionnaire, State-Trait-Anxiety Inventory, Hospital-Anxiety and Depression-scale, MRI-Fear-Survey-Schedule and the MRI-Anxiety-Questionnaire. Motion artefacts were evaluated by three observers, blinded to the information given. Data were collected between April 2015 and April 2016. The study followed the CONSORT guidelines RESULT: The CMR-video group scored lower (better) than the cardiovascular magnetic resonance imaging-standard group in the factor Relaxation (p=0.039) but not in the factor Anxiety. Anxiety levels were lower during scintigraphic examinations compared to the CMR-standard group (p<0.001). No difference was found regarding motion artefacts between CMR-video and CMR-standard. Conclusion: Patient ability to relax during cardiovascular magnetic resonance imaging increased by adding video information prior the exam, which is important in relation to perceived quality in nursing. No effect was seen on motion artefacts. Relevance To Clinical Practice: Video information prior to examinations can be an easy and time effective method to help patients cooperate in imaging procedures.

    Abstract [en]

    To date, allergen immunotherapy (AIT) is the only treatment that affects the long-term development of allergic rhinoconjunctivitis and induces clinical tolerance primarily by stimulating regulatory T (Treg) cells, attenuating T helper 2 (Th2) responses and synthesis of blocking antibodies1. Conventional AIT with subcutaneous injections, sublingual tablets or drops is effective, but consumes time and resources 2.

    Differences in patient perception of appropriate level of care1996Ingår i: European Journal of General Practice, Vol. 2, nr 3, s. 109-112Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: The principle of achieving the most cost-effective level of care in relation to needs is an essential aim for all health care systems. However, it is not certain that the corresponding knowledge and attitudes with respect to the appropriate level of care for different symptoms can be found in the general population. There may be age-related differences in illness behaviour that manifest in ‘overutilisation’ of the system. We studied illness behaviour with regard to attitudes and inclination to seek care for different symptoms at various levels in the health care system.Methods: The study group consisted of a random selection of 296 persons, born in the 1940s, ′50s and ′60s, and living in a defined region in Sweden. In a questionnaire they had to choose between different levels of care for twelve symptom descriptions with varying degrees of severity. The answers were scored according to the level of care, adequacy and overutilisation.Results: The vast majority of participants chose an adequate level of care. However, overutilisation was found, particularly among women born in the 1960s and to some extent among men born in the 1940s. These two groups together constituted about 70% of all the individuals who tended to overutilise the health care in their expressed preferences.Conclusions: These individuals do not receive cost-effective care, or the most adequate care with regard to their needs. The results indicate, however, that the problem was more a question of attitude rather than a lack of knowledge and information.

    Learning From Incident Reporting?: Analysis of Incidents Resulting in Patient Injuries in a Web-Based System in Swedish Health Care2017Ingår i: Journal of patient safety, ISSN 1549-8417, E-ISSN 1549-8425Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives Incident reporting (IR) systems have the potential to improve patient safety if they enable learningfrom the reported risks and incidents. The aim of this study was to investigate incidents registered in an IR system in a Swedish county council.

    Methods The study was conducted in the County Council of Östergötland, Sweden. Data were retrieved from the IR system, which included 4755 incidents occurring in somatic care that resulted in patient injuries from 2004 to 2012. One hundred correctly classified patient injuries were randomly sampled from 3 injury severity levels: injuries leading to deaths, permanent harm, and temporary harm. Three aspects were analyzed: handling of the incident, causes of the incident, and actions taken to prevent its recurrence.

    Results Of the 300 injuries, 79% were handled in the departments where they occurred. The department head decided what actions should be taken to prevent recurrence in response to 95% of the injuries. A total of 448 causes were identified for the injuries; problems associated with procedures, routines, and guidelines were most common. Decisions taken for 80% of the injuries could be classified using the IR system documentation and root cause analysis. The most commonly pursued type of action was change of work routine or guideline.

    Conclusions The handling, causes, and actions taken to prevent recurrence were similar for injuries of different severity levels. Various forms of feedback (information, education, and dialogue) were an integral aspect of the IR system. However, this feedback was primarily intradepartmental and did not yield much organizational learning.

    Toaletträning lönar sig även vid svår utvecklingsstörning: Råd och anvisningar vid inkontinens2010Ingår i: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 107, nr 37, s. 2164-2168Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [sv]

    Råd och anvisningar för toaletträning vid utvecklingsstörning har efterlysts av föräldrar och vårdpersonal.

    Evidensbaserade riktlinjer enligt SBU:s rekommendationer för handläggning av toaletträning vid utvecklingsstörning har tagits fram efter granskning av befintlig forskning, som nästan uteslutande berör toaletträning vid måttlig, svår eller grav utvecklingsstörning.

    Barnorienterade råd för toaletträning av normalutvecklade barn kan eller ska som regel tillämpas för barn med utvecklingsstörning utan tilläggsproblematik.

    Intensiv strukturerad beteendeträning är sannolikt den bästa metoden för barn och ungdomar med svårare grad av utvecklingsstörning och för individer med neuropsy­kiatriska funktionsnedsättningar.

    Medicinsk bedömning ska alltid föregå toaletträning vid utvecklingsstörning, då neurogena och anatomiska avvikelser är vanligare hos barn och ungdomar med utvecklingsstörning.

    Moving forward in life after being an on-looker in intensive care partner's experience of group-communication2016Konferensbidrag (Refereegranskat)
    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.

    Family Health Conversations create awareness of family functioning.2019Ingår i: Nursing in Critical Care, ISSN 1362-1017, E-ISSN 1478-5153Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The whole family is affected if one family member is critically ill. The Family Health Conversation Intervention may give the family tools that support healthier family functioning.

    AIMS AND OBJECTIVES: The aim of this study was to identify which components of family function are affected when families participate in Family Health Conversations.

    DESIGN: A secondary analysis was performed of existing qualitative interviews. The Family Health Conversation is an intervention where nurses ask the family reflective questions, and reflection is made possible in three conversation sessions.

    METHODS: This study included transcribed data from 13 follow-up interviews from seven families attending Family Health Conversations after three and 12 months. Data were analysed with narrative analysis, focusing on family function.

    RESULTS: Three themes were identified. The families' family functioning had been supported with: improved understanding of each other-there was an understanding of being in the same situation but still having totally different experiences; more concern for each other-they talked about their different experiences and felt they had become closer to each other; and a process of working through-they had experienced working through various experiences, standing by and supporting, and then being able to move on.

    CONCLUSIONS: The Family Health Conversation Intervention is provided to families, accompanied by nurses. The families in this study gained an awareness of their family function that brought the family closer because of improved understanding of each other and the situation. The families experienced openness, and the family members spoke more freely with each other, which facilitated the progress of working through the experience of critical illness and helped to maintain healthy family functioning.

    RELEVANCE TO CLINICAL PRACTICE: It is important to have an overall perspective and to recognize the patient and the family as equally important within the family for awareness of family function.

    Abstract [en]

    Anterior cruciate ligament (ACL) injury is a common injury and is often associated with concomitant injuries to the menisci and cartilage and, in the long term, osteoarthritis. Preventive training programs have shown to be highly effective in terms of reducing the risk for ACL injury in sports. ACL reconstruction is indicated when the patient experiences symtoms of instability (»giving way«) despite rehabilitation with a physiotherapist aiming to gain neuromuscular control of the knee. Early ACL reconstruction may be indicated, for example when the patient desires to return to pivoting contact-sports at high level. Modern surgical technique for ACL reconstruction has evolved rapidly and includes »anatomic reconstruction« and individualized treatment, where each patient’s unique anatomy, injury and requests on knee function are taken into consideration. In Sweden, more than 90% of all ACL reconstructions performed are included into the Swedish National ACL Register.

    Parents' Expectations About Participating in Antenatal Parenthood Education Classes2012Ingår i: The Journal of Perinatal Education, ISSN 1058-1243, Vol. 21, nr 1, s. 11-17Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Our objective was to assess parents' expectations about participating in antenatal parenthood education classes and to determine whether their expectations might be related to gender, age, and educational level. Data from 1,117 women and 1,019 partners residing in three cities in Sweden were collected with a questionnaire in a cross-sectional study. Participants believed that antenatal education classes would help them to feel more secure as parents and to be better oriented toward childbirth. Men had more positive expectations about the childbirth than the women. The participants mostly wanted help in preparing for parenthood and in learning infant care skills, followed by help in preparing for childbirth. The participants' expectations were affected by gender, age, and educational level. The expectant parents appeared to want more focus on preparation for parenthood than on childbirth.

    Parenthood education in Swedish antenatal care: perceptions of midwives and obstetricians in charge.2008Ingår i: The Journal of perinatal education : an ASPO/Lamaze publication, ISSN 1058-1243, Vol. 17, nr 2, s. 21-27Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study was to describe perceptions of parenthood education among midwives and obstetricians in charge of antenatal care in Sweden. Focus group interviews of 25 obstetricians and midwives were conducted. Data were analyzed with a phenomenographic approach. Five main categories emerged: aim of the parenthood education, content and expectations, implementation, support to group leaders, and strategies for the future. There is a strong belief in parenthood education, and the overall aim was considered to be support in the transition to parenthood. Contents should focus on awareness of the expected child, confidence in the biological processes, and the changes of roles. Pedagogies training, cost effectiveness, development, and the need to reach target groups were emphasized.

    Facing the unexpected - A content analysis of how dyads face the challenges of postoperative heart failure2014Ingår i: Clinical Nursing Studies, ISSN 2324-7940, Vol. 2, nr 2, s. 74-83Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: The aim of this study was to identify the challenges, strategies and needs of dyads who are dealing with postoperative heart failure.

    Background: An increasing number of patients with postoperative heart failure are living with their partner as primary caregiver. Heart failure is known to reduce quality of life but little is known about the strategies dyads use to cope with postoperative heart failure or what kind of support they need.

    Methods: Data were collected through semi-structured dialogue guides. Content analysis was performed to derive the main themes and categories of the data.

    Results: Three main themes were derived from the data; Everyday challenges, Strategies to deal with everyday challenges and Factors facilitating everyday life.

    Conclusions: Dyads living with postoperative heart failure find the change in everyday life challenging, but have strategies to handle the situation and know what kind of help they need. With the right help from health care, quality of life and self-care can be improved.

    Necrotising Enterocolitis: epidemiology and imaging2017Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Necrotising enterocolitis (NEC) is a potentially devastating intestinal inflammation of multifactorial aetiology in premature or otherwise vulnerable neonates. Because of the broad spectrum of presentations, diagnosis and timing of surgical intervention may be challenging, and imaging needs to be an integrated part of management.

    The first four studies included in this thesis used routinely collected, nationwide register data to describe the incidence of NEC in Sweden 1987‒2009, its variation with time, seasonality, space-time clustering, and associations with maternal, gestational, and perinatal factors, and the risk of intestinal failure in the aftermath of the disease.

    Early infant survival increased dramatically during the study period. The incidence rate of NEC was 0.34 per 1,000 live births, rising from 0.26 per 1,000 live births in the first six years of the study period to 0.57 in the last five. The incidence rates in the lowest birth weights were 100‒160 times those of the entire birth cohort. Seasonal variation was found, as well as space-time clustering in association with delivery hospitals but not with maternal residential municipalities.

    Comparing NEC cases with matched controls, some factors, positively associated with NEC, were isoimmunisation, fetal distress, caesarean section, persistent ductus arteriosus, cardiac and gastrointestinal malformations, and chromosomal abnormalities. Negative associations included maternal pre-eclampsia, maternal urinary infection, and premature rupture of the membranes. Intestinal failure occurred in 6% of NEC cases and 0.4% of controls, with the highest incidence towards the end of the study period.

    The last study investigated current practices and perceptions of imaging in the management of NEC, as reported by involved specialists. There was great consensus on most issues. Areas in need of further study seem mainly related to imaging routines, the use of ultrasound, and indications for surgery.

    Developing alongside the progress of neonatal care, NEC is a complex, multifactorial disease, with shifting patterns of predisposing and precipitating causes, and potentially serious long-term complications. The findings of seasonal variation, spacetime clustering, and negative associations with antenatal exposure to infectious agents, fit into the growing understanding of the central role of bacteria and immunological processes in normal maturation of the intestinal canal as well as in the pathogenesis of NEC. Imaging in the management of NEC may be developed through future studies combining multiple diagnostic parameters in relation to clinical outcome.

    OBJECTIVE: To investigate temporal, seasonal, and geographic variations in the incidence of necrotizing enterocolitis (NEC) and its relation to early infant survival in the Swedish population and in subgroups based on gestational age, birth weight, and gender. less thanbrgreater than less thanbrgreater thanMETHODS: In the Swedish birth cohort of 1987 through 2009 all children with a diagnosis of NEC were identified in the National Patient Register, the Swedish Medical Birth Register, and the National Cause of Death Register. NEC incidence, early mortality, and seasonality were analyzed with descriptive statistics, Poisson regression, and auto regression. less thanbrgreater than less thanbrgreater thanRESULTS: The overall incidence of NEC was 3.4 in 10 000 live births, higher in boys than in girls (incidence rate ratio 1.22, 95% confidence interval 1.06-1.40, P = .005), with a peak in November and a trough in May, and increased with an average of similar to 5% a year during the study period. In most subgroups, except the most immature, an initial decrease was followed by a steady increase. Seven-day mortality decreased strongly in all subgroups over the entire study period (annual incidence rate ratio 0.96, 95% confidence interval 0.95-0.96, P andlt; .001). This was especially marked in the most premature and low birth weight infants. less thanbrgreater than less thanbrgreater thanCONCLUSIONS: After an initial decrease, the incidence of NEC has increased in Sweden during the last decades. An association with the concurrent dramatically improved early survival seems likely.

    Abstract [en]

    Aim: This study investigated space-time clustering of neonatal necrotising enterocolitis over three decades. Methods: Space-time clustering analyses objects that are grouped by a specific place and time. The Knox test and Kulldorffs scan statistic were used to analyse space-time clusters in 808 children diagnosed with necrotising enterocolitis in a national cohort of 2 389 681 children born between 1987 and 2009 in Sweden. The municipality the mother lived in and the delivery hospital defined closeness in space and the time between when the cases were born - seven, 14 and 21 days - defined closeness in time. Results: The Knox test showed no indication of space-time clustering at the residential level, but clear indications at the hospital level in all the time windows: seven days (p = 0.026), 14 days (p = 0.010) and 21 days (p = 0.004). Significant clustering at the hospital level was found during 1987-1997, but not during 1998-2009. Kulldorffs scan statistic found seven significant clusters at the hospital level. Conclusion: Space-time clustering was found at the hospital but not residential level, suggesting a contagious environmental effect after delivery, but not in the prenatal period. The decrease in clustering over time may reflect improved routines to minimise the risk of contagion between patients receiving neonatal care.

    Abstract [en]

    Objective

    To analyze associations of maternal, fetal, gestational, and perinatal factors with necrotizing enterocolitis in a matched case-control study based on routinely collected, nationwide register data.

    Study design

    All infants born in 1987 through 2009 with a diagnosis of necrotizing enterocolitis in any of the Swedish national health care registers were identified. For each case up to 6 controls, matched for birth year and gestational age, were selected. The resulting study population consisted of 720 cases and 3,567 controls. Information on socioeconomic data about the mother, maternal morbidity, pregnancy related diagnoses, perinatal diagnoses of the infant, and procedures in the perinatal period, was obtained for all cases and controls and analyzed with univariable and multivariable logistic regressions for the whole study population as well as for subgroups according to gestational age.

    Results

    In the study population as a whole, we found independent positive associations with necrotizing enterocolitis for isoimmunization, fetal distress, cesarean section, neonatal bacterial infection including sepsis, erythrocyte transfusion, persistent ductus arteriosus, cardiac malformation, gastrointestinal malformation, and chromosomal abnormality. Negative associations were found for maternal weight, preeclampsia, maternal urinary infection, premature rupture of the membranes, and birthweight. Different patterns of associations were seen in the subgroups of different gestational age.

    Conclusion

    With some interesting exceptions, especially in negative associations, the results of this large, population based study, are in keeping with earlier studies. Although restrained by the limitations of register data, the findings mirror conceivable pathophysiological processes and underline that NEC is a multifactorial disease.

    Abstract [en]

    Objectives

    To investigate current practices and perceptions of imaging in necrotising enterocolitis (NEC) according to involved specialists, put them in the context of current literature, and identify needs for further investigation.

    Methods

    Two hundred two neonatologists, paediatric surgeons, and radiologists answered a web-based questionnaire about imaging in NEC at their hospitals. The results were descriptively analysed, using proportion estimates with 95% confidence intervals.

    Results

    There was over 90% agreement on the value of imaging for confirmation of the diagnosis, surveillance, and guidance in decisions on surgery as well as on abdominal radiography as the first-choice modality and the most important radiographic signs. More variation was observed regarding some indications for surgery and the use of some ultrasonographic signs. Fifty-eight per cent stated that ultrasound was used for NEC at their hospital. Examination frequency, often once daily or more but with considerable variations, and projections used in AR were usually decided individually rather than according to fixed schedules. Predicting the need of surgery was regarded more important than formal staging.

    Conclusion

    Despite great agreement on the purposes of imaging in NEC and the most important radiographic signs of the disease, there was considerable diversity in routines, especially regarding examination frequency and the use of ultrasound. Apart from continuing validation of ultrasound, important objectives for future studies include definition of the supplementary roles of both imaging modalities in relation to other diagnostic parameters and evaluation of various imaging routines in relation to timing of surgery, complications, and mortality rate.

    OBJECTIVE: To investigate temporal, seasonal, and geographic variations in the incidence of necrotizing enterocolitis (NEC) and its relation to early infant survival in the Swedish population and in subgroups based on gestational age, birth weight, and gender. less thanbrgreater than less thanbrgreater thanMETHODS: In the Swedish birth cohort of 1987 through 2009 all children with a diagnosis of NEC were identified in the National Patient Register, the Swedish Medical Birth Register, and the National Cause of Death Register. NEC incidence, early mortality, and seasonality were analyzed with descriptive statistics, Poisson regression, and auto regression. less thanbrgreater than less thanbrgreater thanRESULTS: The overall incidence of NEC was 3.4 in 10 000 live births, higher in boys than in girls (incidence rate ratio 1.22, 95% confidence interval 1.06-1.40, P = .005), with a peak in November and a trough in May, and increased with an average of similar to 5% a year during the study period. In most subgroups, except the most immature, an initial decrease was followed by a steady increase. Seven-day mortality decreased strongly in all subgroups over the entire study period (annual incidence rate ratio 0.96, 95% confidence interval 0.95-0.96, P andlt; .001). This was especially marked in the most premature and low birth weight infants. less thanbrgreater than less thanbrgreater thanCONCLUSIONS: After an initial decrease, the incidence of NEC has increased in Sweden during the last decades. An association with the concurrent dramatically improved early survival seems likely.

    Space-time clustering of necrotizing enterocolitis supports the existence of transmissible causes.2017Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Problem Statement: Despite great efforts to prevent necrotizing enterocolitis (NEC) the incidence may in fact be increasing, and changes in the patient population over time seem to lead to changes in clinical presentation and risk factor spectrum as well. The presence of bacteria is an important prerequisite in the pathogenesis, but, rather than being caused by specific pathogens, inflammation and bacterial invasion are thought to be mediated through erroneous interaction between microbiota and innate immunity during colonization of the gut. There are, however, reports of episodic outbreaks of NEC, seasonal variation in incident rates, and clustering, suggesting a role for transmissible infectious agents or other environmental factors around the pregnant mother or newborn infant. In order to investigate evidence for such factors we have analyzed the occurrence of space-time clusters in Sweden over 23 years. Methods: A national register-based cohort of all children born between 1987 and 2009 in Sweden, diagnosed with NEC, was identified. The Knox test and Kulldorff’s scan method were used to analyze signs of space-time clusters at two geographical levels; the mother’s residential address and the delivery hospital. Time windows of seven, 14 and 21 days were used for closeness in time. Results: The Knox test showed clustering on hospital level in all studied temporal windows; seven days (p=0.022) 14 days (p=0.011) and 21 days (p=0.006), and Kulldorff’s scan method found seven significant clusters. On residential level, there was no indication of space-time interaction. When comparing two time periods, significant clustering on hospital level was found during 1987-1997, but not during 1998-2009. Conclusion: Space-time clustering was found on hospital level, but not on community level, suggesting a contagious environmental effect at and after delivery but not in the materno-fetal environment outside the hospital before birth. The decrease in clustering over time suggests that improved routines in neonatal care have minimized the risk of NEC precipitating contagions spreading between patients in the neonatal intensive care unit. The importance of such routines should not be forgotten while our efforts to bring down NEC incidence are directed towards other challenges.

    The significance of radiographic and ultrasonographic findings in the management of necrotising enterocolitis - results from a survey2017Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Necrotising Enterocolitis (NEC) remains a potentially devastating emergency in neonates, predominantly the premature. Ever since it was first described in the 60's, imaging has played a great role in definition, staging, and monitoring of the disease. The radiographic image can change before the clinical condition, but typical signs are often transient and may be missing even in severe NEC [1-4]. These circumstances have led to the recommendation of frequent imaging and to the insight that the clinical decisions cannot rely solely on radiological signs [5-7]. Ultrasound (US) as a possibility to enhance sensitivity and diagnostic accuracy was first described in the mid 80's [8, 9] and was included in a diagnostic algorithm suggested by in 1994 [6], but despite great effort to develop and validate the method, its role in the management of NEC has not yet been established [7, 10, 11].

    Meanwhile, in order to improve interobserver agreement and diagnostic accuracy of AR, the radiographic signs of NEC have also been systematized into the DAAS scale [12]. Imaging, as an adjunct to clinical assessment [11], is crucial in the diagnosis and management of NEC. The purpose of this survey was to investigate current views and routines, as described by involved specialists, and identify areas in need of further study and discussion.

    Limited effect on NS3-NS4A protein cleavage after alanine substitutions within the immunodominant HLA-A2-restricted epitope of the hepatitis C virus genotype 3a non-structural 3/4A protease2012Ingår i: Journal of General Virology, ISSN 0022-1317, E-ISSN 1465-2099, Vol. 93, s. 1680-1686Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It has been well established that immunological escape mutations within the hepatitis C virus genotype (gt) la non-structural (NS) 3/4A protease are partly prevented by a reduction in viral protease fitness. Surprisingly little is known about whether similar mutations affect proteases from other genotypes. In the present study, we assessed both the HLA-A2-restricted CTL response and gt3a NS3/4A protease fitness. Similar to gt1, the 1073-1081 epitope was immunodominant within the gt3a-specific HLA-A2-restricted CTL response, despite sequence similarity of only 56% between the gt1a and gt3a genes. However, unlike the gt1a NS3/4A protease, all residues within the gt3a 1073-1081 epitope could be replaced sequentially by alanine while retaining protease activity, at least in part.

    Platelet-derived growth factor-BB modulates membrane mobility of ß1 integrins2004Ingår i: Biochemical and Biophysical Research Communications - BBRC, ISSN 0006-291X, E-ISSN 1090-2104, Vol. 314, nr 1, s. 89-96Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Platelet-derived growth factor (PDGF)-BB elicits a migratory response including reorganization of the actin cytoskeleton in different cell types. Here we have investigated the effects of PDGF-BB stimulation on ß 1 integrin containing focal adhesions in human diploid fibroblasts adhered to collagen type I. Stimulation with PDGF-BB dissociated focal adhesions and relocated ß1 integrins from focal adhesions to the periphery of the cells. These changes were rapid and transient in character. Relocation of ß1 integrins was prevented by inhibitors of phosphoinositide-3-kinase and protein kinase C. PDGF-BB stimulated fibroblasts exhibited an increased diffusion coefficient of cell surface ß1 integrins as determined by fluorescence recovery of photobleaching. The cell surface expression of ß1 integrins was not changed after stimulation with PDGF-BB. Our data suggest that PDGF-BB increases the dynamic properties of cell-surface ß1 integrins, which most likely are important for the migratory response elicited by PDGF-BB. © 2003 Elsevier Inc.

    Prolongation of the ejaculation latency in the male rat by thioridazine and chlorimipramine.1979Ingår i: Psychopharmacology, ISSN 0033-3158, E-ISSN 1432-2072, Vol. 65, nr 2, s. 137-140Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Thioridazine (3 mg/kg) and chlorimipramine (1.5–6.0 mg/kg) prolonged the ejaculation latency and increased the number of mounts but did not change the number of intromissions preceding ejaculation. Blockade of peripheral and central noradrenaline receptors by phentolamine and phenoxybenzamine respectively resulted in a suppression of all aspects of the sexual behavior with increasing doses. dl-5-HTP (25–100 mg/kg) in combination with an inhibitor of peripheral 5-HTP decarboxylase (benserazide, 25 mg/kg) produced, like chlorimipramine and thioridazine, a prolongation of ejaculation latency and an increase in the number of mounts preceding ejaculation. Selective inhibition of 5-HT reuptake however, by zimelidine (0–20 mg/kg) or alaproclate (0–20 mg/kg) did not affect the mating behavior. At higher doses of these drugs some animals failed to initiate sexual activities. There was an increase in the postejaculatory interval but no change in the ejaculatory latency.It is concluded that the prolonged ejaculation latencies observed following treatment with thioridazine or chlorimipramine is not due to a blockade of central or peripheral adrenergic -receptors.

    Cerebral complications after cardiac surgery2002Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Cerebral injuty remains a major cause of morbidity and mortality after cardiac surgery. Previous studies have mainly focused on preoperative risk factors and intraoperative events but cerebral complications may also occur in the postoperative period. Cognitive impairment is common after cardiac surgery but the consequences of this complication for activities of daily life are less known. Safe driving involves a complex set of skills requiring preserved cognitive function. A substantial number of patients with heart disease are active drivers. The impact of postoperative cognitive dysfunction on driving performance, however, has not previously been investigated in this large patient group.

    In this thesis pre-, intra- and postoperative risk factors for focal cerebral complications were determined and the onset time of cerebral symptoms were evaluated in two cohorts of cardiac surgical patients, comprising 2480 and 3282 patients respectively. Data analysed were drafted from a clinical register and the surgical database of Linköping University Hospital Heart Center. Cerebral complication was delayed, i.e occurred after a free interval, in about one third of patients suggesting causes other than intraoperative events. Different risk factors were found for early and delayed cerebral complications suggesting different mechanisms of cerebral injury. Advanced age, preoperative hypertension, aortic surgery, prolonged cardiopulmonary bypass (CPB) time, intraoperative hypotension after completion of CPB, and arrhytlunia in the early postoperative period increased the risk for early cerebral complication. Female gender, diabetes, previous cerebrovascular disease, combined coronary artery bypass grafting (CABG) and valve surgery and arrhythmia on the thoracic ward increased the risk for delayed cerebral complication. Cognitive function and driving performance were evaluated in 27 patients before and 4-6 weeks after CABG. The patients underwent neuropsychological testing, an on-road driving test and a test in an advanced driving simulator. Twenty patients scheduled for percutaneous coronary intervention (PCI) served as controls. Complete data were obtained in 23 and 19 patients respectively. Furthermore cognitive function and driving performance in on-road driving of the 44 patients with complete tests before intervention were compared with controls of similar age without heart symptoms. Cognitive function and driving performance were already impaired in patients with coronary artery disease before intervention when compared with controls. After surgery 48% of the patients showed cognjtive decline compared to 10% after PCI. These patients also scored less in the on-road driving test to a greater extent than did patients without postoperative cognitive decline.

    Abstract [en]

    Objectives: Cerebral complications continue to be a major cause of morbidity after cardiac surgery. Earlier studies have mainly focused on intraoperative events, but symptoms may also occur later in the postoperative period. The purpose of this study was to determine the incidence and risk factors of focal neurologic complications and timing of cerebral symptoms.

    Design: A retrospective study.

    Setting: Linköping University Hospital.

    Participants: Two thousand four hundred eighty patients who underwent cardiac surgery from 1992 to 1995.

    Interventions: Standard cardiopulmonary bypass (CPB) technique was used in all patients. Anticoagulant treatment included heparin and patients with coronary artery surgery were also administered acetylsalicylic acid and valve-surgery patients received warfarin or dicumarol.

    Measurements and Main Results: Seventy-five patients (3%) had focal neurologic deficits and/or confusion postoperatively. In 32 patients (43%), the onset was not intraoperative but occurred later in the postoperative period. The lowest incidence of cerebral complications was found in patients who underwent single-valve replacement (1.2%) and the highest incidence was found in patients who underwent combined procedures (valve and coronary artery surgery; 7.6%). Patients greater than 70 years of age had a complication rate of 4.1% compared with 2.5% in patients aged 70 years and less (p < 0.05). The incidence of diabetes mellitus was 11.4% in the entire series, but was more common (18.7%; p < 0.05) in patients with cerebral symptoms. Also, 5.9% of all patients had a history of cerebrovascular disease compared with 14.7% (p < 0.01) of patients with cerebral complications.

    Conclusion: Cerebral complications may be delayed after cardiac surgery, suggesting causes of cerebral damage other than intraoperative events. Valve-surgery patients had the lowest incidence and patients with combined procedures had the highest incidence of cerebral complications. Advanced age, diabetes mellitus, and preexisting cerebrovascular disease increased the risk.

    Abstract [en]

    Objective: To report the incidence, severity, and possible risk factors for early and delayed cerebral complications.

    Design: Retrospective study.

    Setting: Linköping University Hospital, Sweden.

    Participants: Consecutive patients who underwent cardiac surgery in the period July 1996 through June 2000 (n = 3,282).

    Interventions: A standard cardiopulmonary bypass (CPB) technique was used for most patients. Postoperative anticoagulant treatment included heparin or anti-Xa dalteparin. Patients undergoing coronary artery bypass graft surgery received acetylsalicylic acid, and patients undergoing valve surgery received warfarin.

    Measurements and Main Results: Cerebral complications occurred in 107 patients (3.3%). Of these, 60 (1.8%) were early, and 33 (1.0%) were delayed, and in 14 (0.4%) patients the onset was unknown. There were 37 variables in univariate analysis (p < 0.15) and 14 variables in multivariate analysis (p < 0.05) associated with cerebral complications. Predictors of early cerebral complications were older age, preoperative hypertension, aortic aneurysm surgery, prolonged CPB time, hypotension at CPB completion and soon after CPB, and postoperative arrhythmia and supraventricular tachyarrhythmia. Predictors of delayed cerebral complications were female gender, diabetes, previous cerebrovascular disease, combined valve surgery and coronary artery bypass graft surgery, postoperative supraventricular tachyarrhythmia, and prolonged ventilator support. Early cerebral complications seem to be more serious, with more permanent deficits and a higher overall mortality (35.0% v 18.2%).

    Conclusion: Most cerebral complications had an early onset. The results of this study suggest that aggressive antiarrhythmic treatment and blood pressure control may imfurther prove the cerebral outcome after cardiac surgery.

    Abstract [en]

    Cognitive ability is essential for the fitness to drive. Impaired cognitive functions are common after cardiac surgery. Little is known about driving habits and influence of postoperative cognitive decline on driving performance in these patients. The aim of this study was to investigate the extent of driving activity of patients before and after cardiac surgery. Ninety-seven cardiac surgical patients were interviewed about their driving habits before and 12 weeks after surgery. The mean age was 66. Before the operation, 78% were active car drivers. They drove several times a week including longer than 100 km distances. After the operation, 64% continued to drive and most of them (69%) had commenced driving within 6 weeks. The majority (79%) reported unchanged driving habits, while 13 patients (21%) had reduced their driving activity due to the cognitive symptoms they experienced. Patients with coronary artery disease are active car drivers both before and after heart surgery. Further evaluation of the ability of these patients to drive is required if we are to give advice and apply restrictions in the interest of traffic safety.

    Abstract [en]

    Objective: Neurocognitive impairment is common after cardiac surgery but few studies have examined the relationship between postoperative neuropsychological test performance and everyday behavior. The influence of postoperative cognitive impairment on car driving has previously not been investigated. The purpose of this study was to evaluate neurocognitive function and driving performance after coronary artery bypass grafting (CABG).

    Methods: Twenty-seven patients who underwent coronary artery bypass grafting with standard cardiopulmonary bypass technique and 20 patients scheduled for percutaneous coronary intervention (PCI) under local anesthesia (control group) were enrolled in this prospective study conducted from April 1999 to September 2000. Complete data were obtained in 23 and 19 patients, respectively. The patients underwent neuropsychological examination with a test battery including 12 tests, a standardized on-road driving test and a test in an advanced driving simulator before and 4–6 weeks after intervention.

    Results: More patients in the coronary artery bypass grafting group (n=11, 48%) than in the percutaneous coronary intervention group (n=2, 10%) showed a cognitive decline after intervention (P=0.01). In the on-road driving test, patients who underwent coronary artery bypass grafting deteriorated after surgery in the cognitive demanding parts like traffic behavior (P=0.01) and attention (P=0.04). Patients who underwent percutaneous intervention deteriorated in maneuvering of the vehicle (P=0.04). No deterioration was detected in the simulator in any of the groups after intervention. Patients with a cognitive decline after intervention also tended to drop in the on-road driving scores to a larger extent than did patients without a cognitive decline.

    Conclusion: This study indicates that cognitive functions important for safe driving may be influenced after cardiac surgery.

    Abstract [en]

    Objectives To compare patients with coronary artery disease and healthy controls with respect to cognitive function and driving performance.

    Design and setting A controlled study conducted between April 1999 and January 2001.

    Subjects Forty-four patients with stable coronary artery disease scheduled for cardiac intervention with coronary artery bypass surgery or percutaneous coronary intervention. Forty volunteers of similar age without symptoms of coronary artery disease served as controls.

    Main outcome measures On-road driving scores in five specific test areas with a rating scale from 1 to 5. Neuropsychological test scores, including 12 tests.

    Results Compared with controls, patients with coronary artery disease had lower scores in all areas of the on-road driving test (p<0.05) and in the neuropsychological tests assessing psychomotor speed, visual and verbal memory, focused attention and simultaneous capacity (p<0.05). The difference between the groups in the on-road driving test appeared to be more pronounced among those above 65 years-of-age. Both patients and controls rated their performance significantly higher than the traffic inspector (p<0.05).

    Conclusions Cognitive function and driving performance may be impaired in patients with coronary artery disease.

    Consumers on the Internet: ethical and legal aspects of commercialization of personalized nutrition2013Ingår i: Genes & Nutrition, ISSN 1555-8932, E-ISSN 1865-3499, Vol. 8, nr 4, s. 349-355Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Consumers often have a positive attitude to the option of receiving personalized nutrition advice based upon genetic testing, since the prospect of enhancing or maintaining one’s health can be perceived as empowering. Current direct-to-consumer services over the Internet, however, suffer from a questionable level of truthfulness and consumer protection, in addition to an imbalance between far-reaching promises and contrasting disclaimers. Psychological and behavioral studies indicate that consumer acceptance of a new technology is primarily explained by the end user’s rational and emotional interpretation as well as moral beliefs. Results from such studies indicate that personalized nutrition must create true value for the consumer. Also, the freedom to choose is crucial for consumer acceptance. From an ethical point of view, consumer protection is crucial, and caution must be exercised when putting nutrigenomic-based tests and advice services on the market. Current Internet offerings appear to reveal a need to further guaranty legal certainty by ensuring privacy, consumer protection and safety. Personalized nutrition services are on the borderline between nutrition and medicine. Current regulation of this area is incomplete and undergoing development. This situation entails the necessity for carefully assessing and developing existing rules that safeguard fundamental rights and data protection while taking into account the sensitivity of data, the risks posed by each step in their processing, and sufficient guarantees for consumers against potential misuse.

    Kartläggning av barn i behov av stöd år 2002: Eksjö kommun2003Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Följande rapport bygger på enkätsvar från olika myndigheter i Eksjö kommun som har rapporterat de barn/ungdomar i åldern 0-18 år som man i sin verksamhet kommer i kontakt med och som man känner oro för, p.g.a. en ogynnsam utveckling. Tjugo förutbestämda kriterier användes för att beskriva orsaken till myndighetens oro. Myndigheterna har också rapporterat om de insatser som görs redan idag samt om man bedömer att det kan bli aktuellt med ytterligare insatser nu eller i framtiden.

    Totalt inrapporterades 842 barn och ungdomar. Socialförvaltningen rapporterade 78 barn och ungdomar, Barnavårdscentralen 30 barn och skolan 689 barn och ungdomar. Av 45 enkätsvar framgår det inte vem som är rapportör. Vid bearbetningen av insamlat material har 10 enkätsvar uteslutits eftersom de inte var tillräckligt ifyllda. 103 enkätsvar uteslöt för att de flerrapporterade barn och/eller ungdomar och 17 enkätsvar uteslöts eftersom de rapporterade ungdomar som inte är skrivna i Eksjö kommun. Slutligen kom 712 barn och ungdomar att ingå i kartläggningen. Detta är drygt 18,8 % av alla aktuella barn och ungdomar. Av dessa är en klar majoritet pojkar (446 dvs. 62,6 %). För hela målgruppen främst tre huvudorsaker som ger anledning till oro hos berörda myndigheter. Det är;

    1. Föräldrarna brister i omsorgen, i stödet till den unge eller möjligheten att ge stimulans pågrund av sociala, mentala, fysiska eller psykiska handikapp och/eller missbruksproblem. För130 (av 712) barn och ungdomar anser man att det är huvudorsaken till oro.
    2. Barn/ungdomar som är introverta (tysta, blyga, nedstämda, mutister). För 69 av (712) barnoch ungdomar är det huvudorsaken till att man känner oro.
    3. Föräldrars separation eller ständiga konflikter påverkar den unge negativt. För 66 av (712)barn och ungdomar är det huvudorsaken till att man känner oro.

    Resultatredovisningen visar att skolan är den myndighet vars insatser dominerande är det också så att olika insatser inom skolan dominerar. Vanligast är undervisning i liten grupp och olika typer av specialundervisning. Olika typer av anpassad studiegång är också en vanlig insats att möta barn och ungdomar med olika svårigheter. Även olika psykosociala åtgärder förekommer också t.ex. stödsamtal med skolsköterska eller kurator. Vanligast av socialförvaltningens insatser är kontaktperson/familj.

    Berörda myndigheter uppmanas också att föreslå olika typer av nya insatser för de rapporterade barnen och ungdomarna. Även här dominerar olika typer av skolinriktade insatser. Vanliga förslag är undervisning i liten grupp och/eller olika typer av specialundervisning. När socialförvaltningen anses vara ansvarig myndigheter för önskade insatser föreslår rapporterande myndigheter allt från olika typer av familjestöd till direkta förslag till omhändertagande och placering på behandlingshem.

    MicroRNAs as circulating biomarkers in acute coronary syndromes: A review2016Ingår i: Vascular pharmacology, ISSN 1537-1891, E-ISSN 1879-3649, Vol. 81, s. 15-21Artikel, forskningsöversikt (Refereegranskat)
    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.
