    Prognostic Assessment of Elderly Patients with Symptoms of Heart Failure by Combining High-Sensitivity Troponin T and N-Terminal Pro-B-Type Natriuretic Peptide Measurements2010In: CLINICAL CHEMISTRY, ISSN 0009-9147, Vol. 56, no 11, 1718-1724 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a useful biomarker in heart failure assessment, whereas measurement of cardiac troponin is central in the diagnosis of patients with acute coronary syndromes. This report examined the prognostic use of combining high-sensitivity cardiac troponin T (hs-cTnT) and NT-proBNP measurements in elderly patients presenting to a primary care center with symptoms associated with heart failure. METHODS: A total of 470 elderly patients (age range 65-86 years) presenting with symptoms of heart failure were recruited from primary healthcare. In addition to clinical examination and echocardiography, hs-cTnT and NT-proBNP plasma concentrations were measured. All patients were followed for 10 years, and cardiovascular mortality was registered. RESULTS: By use of the hs-cTnT assay, 80.4% of the population had plasma concentrations above the lower detection limit of the assay. Of those displaying a plasma concentration of hs-cTnT andgt;99th percentile of a healthy population, 43% also had an NT-proBNP concentration in the fourth quartile (andgt;507 ng/L). In the multivariate analysis, we observed a 2.5-fold increased risk for cardiovascular mortality in individuals with a plasma NT-proBNP concentration andgt;507 ng/L (P andlt; 0.0001). Conversely, patients with hs-cTnT andgt;99th percentile displayed an approximately 2-fold increased risk for cardiovascular mortality (P = 0.0002). Combining the 2 biomarkers, NT-proBNP concentrations andgt;507 ng/L with hs-cTnT andgt;99th percentile increased the risk 3-fold, even after adjustment for clinical variables such as age, sex, impaired estimated glomerular filtration rate, and anemia (P andlt; 0.0001). CONCLUSIONS: hs-cTnT and NT-proBNP measurements combined provide better prognostic information than using either biomarker separately in elderly patients with symptoms associated with heart failure.

    Are There Any Significant Differences Between Females and Males in the Management of Heart Failure? Gender Aspects of an Elderly Population With Symptoms Associated With Heart Failure2009In: JOURNAL OF CARDIAC FAILURE, ISSN 1071-9164, Vol. 15, no 6, 501-507 p.Article in journal (Refereed)
    Abstract [en]

    Background: An increasing interest has been shown in potential l., 11 With heart failure (HF), a serious condition for the individual. To evaluate whether there are any differences ill the prevalence of HF, cardiac function, biomarkers. and the treatment of HF with respect to gender. Methods and Results: All persons ages 70 to 80 in a rural municipality were invited to participate ill the project 876 persons accepted. Three cardiologists evaluated the patients including a new history, clinical examination. electrocardiogram, chest x-ray. blood samples. and Doppler echocardiography to assess both Systolic and diastolic function. The patients were followed during a mean period of 8 years. Conclusion: Females hypertension more frequently and included fewer smokers than their male Counterparts. A Female preponderance was seen in those with preserved systolic function. whereas males predominated among those with systolic dysfunction. During the follow-up period, 20% of the males and 14% of the females died of cardiovascular diseases. The results did not show any inferior treatment of females with HF. but it clearly was more difficult to correctly classify female patients presenting with symptoms of HE

    Heart failure in the elderly: characteristics of a Swedish primary health care population2002In: Heart Drug, ISSN 1422-9528, E-ISSN 1424-0556, Vol. 2, no 5, 211-220 p.Article in journal (Refereed)
    Abstract [en]

    Background: Heart failure (HF) is a challenge to diagnose and treat according to guidelines. Few studies have been performed in elderly subjects with symptoms that might be associated with HF in primary health care.

    Objective: To study elderly patients presenting with symptoms possibly associated with HF, with respect to systolic and diastolic function, B-type natriuretic peptide (BNP) levels and treatment.

    Methods: A cardiologist examined 415 elderly (65–82 years) patients with symptoms of dyspnoea, fatigue and/or peripheral oedema. All patients underwent echocardiography and plasma BNP determination. Systolic function was determined semiquantitatively, and ejection fraction (EF) <40% was considered to be reduced. Abnormal diastolic function was defined as a reduced ratio of peak early diastolic filling velocity to peak filling velocity at atrial contraction (E/A ratio; age adjusted) or an abnormal pattern of pulmonary venous flow.

    Results: Forty-eight percent of the patients showed abnormal systolic (26%) or diastolic function (22%). A majority of the patients with diastolic HF had relaxation abnormalities and neither pseudonormal nor restrictive filling patterns. Increased levels of BNP were found in the group with impaired systolic function. More than half of those with EF <40% were not receiving angiotensin-converting enzyme inhibitions at all, or were on a suboptimal dose, whereas others were on treatment for an HF diagnosis despite normal cardiac function.

    Conclusion: Diagnostic tools that are more objective than clinical examination are needed for the diagnosis of HF.

    Reference intervals and decision limits for B-type natriuretic peptide (BNP) and its precursor (Nt-proBNP) in the elderly2007In: Clinica Chimica Acta, ISSN 0009-8981, Vol. 382, no 1-2Article in journal (Refereed)
    Abstract [en]

    Background: Elderly patients have the highest prevalence of heart failure (HF). The aims of the study were to establish a reference interval for B-type natriuretic peptide (BNP) and (Nt-proBNP) in elderly people, and to identify clinically relevant decision limits based on long-term outcome. Methods: Plasma concentrations of BNP and Nt-proBNP were measured from two elderly populations: 218 healthy subjects (mean age 73 years, population I), and 474 patients (mean age 73 years, population II) with symptoms associated with HF. Study population II was followed for 6 years with registration of all cardiovascular mortality. Results: An association between both BNP and Nt-proBNP concentrations and age was found. The upper limit for the reference intervals in the healthy elderly (population I) was: BNP ≤ 28 pmol/L (≤ 97 ng/L), and Nt-proBNP ≤ 64 pmol/L (≤ 540 ng/L). Based on cardiovascular mortality, decision limits for BNP (∼ 50 pmol/L, ∼ 170 ng/L) and Nt-proBNP (∼ 200 pmol/L, ∼ 1700 ng/L) (population II) were determined. Conclusions: Besides establishing reference intervals for BNP and Nt-proBNP in an elderly population, a higher clinically relevant decision limit for BNP and Nt-proBNP was identified, indicating additive prognostic information of the peptides on top of measurements by echocardiography. Therefore, both reference intervals and decision limits should be included in clinical practice. © 2007.

    A clinician’s experience of using the Cardiac Reader NT-proBNP point-of-care assay in a clinical setting2008In: European Journal of Heart Failure, ISSN 1388-9842, Vol. 10, no 3, 260-266 p.Article in journal (Refereed)
    Abstract [en]

    The evaluation of natriuretic peptides has become increasingly valuable in a clinical setting, where information is often needed promptly.

    Objectives: To compare the usefulness of the recently released Roche Cardiac Reader ® NT-proBNP assay against the Roche Elecsys® NT-proBNP laboratory system in a clinical setting.

    Design and Results: Blood samples from 440 patients admitted for acute coronary syndromes, worsening of heart failure, or as policlinic heart failure patients were evaluated. The relation between the assays was analysed and the diagnostic concordance calculated. A good correlation was found between the assays (r=0.96, 95% CI: 0.94-0.97) with a diagnostic concordance of 0.93. A separate analysis was performed in the range where most clinical decisions are made (60-3000 ng/L), with a diagnostic concordance of 88%. The usefulness in a clinical setting where time is important was high.

    Conclusion: The Roche Cardiac Reader® NT-proBNP assay has been evaluated in a clinical setting. The point-of-care method shows good results, although with a restricted analytical range compared with the reference.

    Cardiovascular mortality and N-terminal-proBNP reduced after combined selenium and coenzyme Q10 supplementation: a 5-year prospective randomized double-blind placebo-controlled trial among elderly Swedish citizens2013In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 167, no 5, 1860-1866 p.Article in journal (Refereed)
    Abstract [en]

    Background

    Selenium and coenzyme Q10 are essential for the cell. Low cardiac contents of selenium and coenzyme Q10 have been shown in patients with cardiomyopathy, but inconsistent results are published on the effect of supplementation of the two components separately. A vital relationship exists between the two substances to obtain optimal function of the cell. However, reports on combined supplements are lacking.

    Methods

    A 5-year prospective randomized double-blind placebo-controlled trial among Swedish citizens aged 70 to 88 was performed in 443 participants given combined supplementation of selenium and coenzyme Q10 or a placebo. Clinical examinations, echocardiography and biomarker measurements were performed. Participants were monitored every 6th month throughout the intervention.

    The cardiac biomarker N-terminal proBNP (NT-proBNP) and echocardiographic changes were monitored and mortalities were registered. End-points of mortality were evaluated by Kaplan–Meier plots and Cox proportional hazard ratios were adjusted for potential confounding factors. Intention-to-treat and per-protocol analyses were applied.

    Results

    During a follow up time of 5.2 years a significant reduction of cardiovascular mortality was found in the active treatment group vs. the placebo group (5.9% vs. 12.6%; P = 0.015). NT-proBNP levels were significantly lower in the active group compared with the placebo group (mean values: 214 ng/L vs. 302 ng/L at 48 months; P = 0.014). In echocardiography a significant better cardiac function score was found in the active supplementation compared to the placebo group (P = 0.03).

    Conclusion

    Long-term supplementation of selenium/coenzyme Q10 reduces cardiovascular mortality. The positive effects could also be seen in NT-proBNP levels and on echocardiography.

    Results from a 6-year follow-up of a Swedish population in primary care regarding b-type natriuretic peptide (bnp) and the aminoterminal fragment of proBNP (n-terminal proBNP) and risk for cardiovascular death in elderly patients with possible heart failure.Manuscript (preprint) (Other academic)
    Abstract [en]

    Abstract

    Heart failure is common in the elderly population and carries a serious prognosis. Identification of risk factors for cardiovascular mortality among primary care patients is important.

    Aim

    To evaluate EDTA-plasma brain natriuretic peptide (BNP) and the aminoterminal fragment of proBNP (N-terminal proBNP) as prognostic markers in elderly with symptoms of mild to moderate heart failure.

    Methods

    From 474 patients attending primary care for symptoms of dyspnoea, fatigue and/or peripheral oedema blood was sampled in plastic tubes containing EDTA in order to measure BNP by non-extraction immunoradiometric assay and of N-terminal proBNP by non-extraction radioimmunoassay. Patients were evaluated with respect to history and clinical- and laboratory examinations with particular reference to cardiac structure and function. Follow-up time was 6 years. A Cox regression analysis was performed to identify the weight of risk variables.

    Conclusion

    During the follow-up period of 6 years the total mortality was 16 % (75 patients out of 474), and cardiovascular mortality was 11% (52 patients). Cardiovascular mortality increased with increased plasma concentration of BNP or N-terminal proBNP. Both pep tides were useful prognostic markers for cardiovascular mortality in patients with heart failure. In those with the highest quartile of plasma concentration of BNP and N=terminal proBNP, 9.9 times and 5.0 times increased risk for CV death were identified respectively.

    Risk of cardiovascular death in elderly patients with possible heart failure. B-type natriuretic peptide (BNP) and the aminoterminal fragment of ProBNP (N-terminal proBNP) as prognostic indicators in a 6-year follow-up of a primary care population2005In: International Journal of Cardiology, ISSN 0167-5273, Vol. 100, no 1, 125-133 p.Article in journal (Refereed)
    Abstract [en]

    Heart failure is common in the elderly population and carries a serious prognosis. We evaluated EDTA-plasma B-type natriuretic peptide (brain natriuretic peptide, BNP) and the aminoterminal fragment of proBNP (N-terminal proBNP) as prognostic markers in elderly primary care patients with symptoms of heart failure. Methods: From 474 patients attending primary care for symptoms of dyspnea, fatigue and/or peripheral edema, blood was sampled in plastic tubes containing EDTA to measure BNP by non-extraction immunoradiometric assay and N-terminal proBNP by non-extraction radioimmunoassay. Patients were evaluated with respect to history and function by NYHA classification and Doppler echocardiography. Follow-up time was 6 years. Cox regression analysis was performed to identify the weight of risk variables. Conclusion: Total 6-year mortality was 20% (102 patients out of 510), and cardiovascular (CV) mortality was 14% (71 patients, 70% of total mortality). BNP and N-terminal proBNP were essentially equally useful as prognostic markers. In patients with the highest quartiles of plasma concentration of BNP and N-terminal proBNP, respectively, the risk of cardiovascular mortality was 10 and 4.8 times, respectively, higher than that in those in the lowest quartile. Peptide concentrations varied widely within all functional groups including those with normal echocardiographic findings. Plasma concentrations of BNP and N-terminal proBNP give important prognostic information concerning risk of cardiovascular mortality. Cost-effective "clinical pathways" should be outlined for patients with elevated peptide concentrations. © 2005 Elsevier Ireland Ltd. All rights reserved.

    The risk of cardiovascular death in elderly patients with possible heart failure: results from a 6-year follow-up of a Swedish primary care population2005In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 100, no 1, 17-27 p.Article in journal (Refereed)
    Abstract [en]

    Little is known about the prognosis and clinical variables influencing the prognosis among elderly patients in primary health care with mild to moderate heart failure.

    Aim: To evaluate the risk of cardiovascular mortality in elderly patients with symptoms of heart failure with respect to systolic and diastolic function, and functional impairment. To evaluate prognostic determinants and to risk-stratify the patients.

    Methods: A cardiologist examined 510 patients, out of 548 invited, attending primary care for symptoms of dyspnoea, fatigue and/or peripheral oedema and assessed New York Heart Association (NYHA) functional class. Examination by Doppler echocardiography was done in 454 patients, 56 patients being excluded because of, e.g., atrial fibrillation. Abnormal systolic function was defined as ejection fraction <40%. The diastolic function was evaluated using the mitral inflow and pulmonary venous flow variables. Different clinical and echocardiographic variables were analysed using a Cox regression analysis to identify those most influencing the risk of cardiovascular mortality.

    Conclusion: Abnormal systolic and/or diastolic function was found in 219 patients (48% of the 454 patients who could be echocardiographically completely investigated). The follow-up period was 6 years. Total mortality was 20%, and cardiovascular mortality was 14% (70% of total mortality). Cardiovascular mortality was high in patients with severely impaired functional capacity and ejection fraction <40% at the start of the study. Risk variables identified were male gender, diabetes mellitus, impaired functional capacity and abnormal cardiac function by echocardiography. A prognostic score model using simple clinical variables (gender, NYHA class, cardiac function) was developed to assess the risk of cardiovascular death in order to identify patients with high, moderate or low risk. In a ROC curve analysis, the AUC for clinical variables was only 0.75, whereas the AUC for clinical variables and echocardiography was 0.78, indicating that the additional prognostic information obtained by Doppler echocardiography was rather small.

    Utility of the amino-terminal fragment of pro-brain natriuretic peptide in plasma for the evaluation of cardiac dysfunction in elderly patients in primary health care2003In: Clinical Chemistry, ISSN 0009-9147, E-ISSN 1530-8561, Vol. 49, no 8, 1337-1346 p.Article in journal (Refereed)
    Abstract [en]

    Background: The aims of this study were to measure the N-terminal fragment of pro-brain natriuretic peptide (proBNP) in plasma in medical conditions commonly found in primary care and to evaluate the utility of these measurements in identifying impaired cardiac function in elderly patients with symptoms associated with heart failure.

    Methods: We studied 415 patients (221 men and 194 women; mean age, 72 years) who had contacted a primary healthcare center for dyspnea, fatigue, and/or peripheral edema. One cardiologist evaluated the patients in terms of history, physical examination, functional capacity, electrocardiography, and suspicion of heart failure. Plasma N-terminal proBNP was measured by an in-house RIA. An ejection fraction ≤40% by Doppler echocardiography was regarded as reduced cardiac function. Abnormal diastolic function was defined as an abnormal mitral inflow defined as reduced ratio of peak early diastolic filling velocity to peak filling velocity at atrial contraction (E/A ratio), or as abnormal pulmonary venous flow pattern.

    Results: Patients with impaired functional capacity, impaired systolic function, and/or impaired renal function had significantly increased N-terminal proBNP concentrations. By multiple regression analysis, N-terminal proBNP concentrations were also influenced by ischemic heart disease, cardiac enlargement, and certain medications but not by increased creatinine. No gender differences were observed. Patients with isolated diastolic dysfunction attributable to relaxation abnormali-ties had lower concentrations than those with normal cardiac function, whereas those with pseudonormal E/A ratios or restrictive filling patterns had higher concentrations.

    Conclusions: Plasma N-terminal proBNP concentrations increase as a result of impaired systolic function, age, impaired renal function, cardiac ischemia and enlargement, and certain medications. Values are high in diastolic dysfunction with pseudonormal patterns, but not in patients with relaxation abnormalities. An increase in plasma N-terminal proBNP might be an earlier sign of abnormal cardiac function than abnormalities identified by currently used echocardiographic measurements.

    Quality-adjusted life year weights among elderly patients with heart failure2008In: European journal of heart failure, ISSN 1388-9842, Vol. 10, no 10, 1033-1039 p.Article in journal (Refereed)
    Abstract [en]

    Background

    When assessing health-related quality of life (HRQoL) in elderly patients with heart failure (HF), the process of obtaining quality-adjusted life year (QALY) weights is generally complicated and time-consuming.

    Aim

    To evaluate whether information regarding HRQoL and QALY weights can be derived directly from the established and widely used New York Heart Association (NYHA) functional classification system.

    Methods

    NYHA functional status was assessed independently both by the individual patients and by the examining cardiologist in 323 elderly patients with symptoms of HF recruited from primary care. HRQoL was evaluated using the SF-36 questionnaire and a time trade-off (TTO) scenario. The TTO technique generates direct QALY weights.

    Results

    Both the TTO technique and SF-36 values demonstrated a statistically significant correlation with NYHA functional status. The TTO values also correlated with all SF-36 dimensions. Increasing impairment was associated with statistically significant drops in both SF-36 values and TTO-based QALY weights. For patients in NYHA classes I–IV the QALY weights were 0.77, 0.68, 0.61, and 0.50, respectively. Thus in elderly patients, symptoms of HF have a major impact on perceived quality of life.

    Conclusion

    The results of the present study show that QALY weights, an important instrument in the health economic evaluation of treatment strategies, can be derived directly from NYHA classification in elderly HF patients.

    Natriuretic Peptide Biomarkers as Information Indicators in Elderly Patients With Possible Heart Failure Followed Over Six Years: A Head-to-Head Comparison of Four Cardiac Natriuretic Peptides2007In: Journal of Cardiac Failure, ISSN 1071-9164, Vol. 13, no 6, 452-461 p.Article in journal (Refereed)
    Abstract [en]

    Background: Little is known about the differences between natriuretic peptides used to evaluate elderly patients with heart failure. The aim of the study was to evaluate the information and the power to predict cardiovascular mortality derived from an analysis of cardiac natriuretic peptides from the same study population and at the same time. Methods and Results: In all, 415 elderly patients (age 65-82 years) in primary health care were evaluated and followed for 6 years. All patients had symptoms of heart failure and were examined by a cardiologist. An electrocardiogram and chest x-rays were taken, and the systolic and diastolic functions were assessed using Doppler echocardiography. Brain natriuretic peptide (BNP), N-terminal proBNP, atrial natriuretic peptide (ANP), and N-terminal proANP were analyzed. All 4 peptides were associated with age, and only 1 of them showed any gender difference. Three of the 4 peptides (not ANP) provided important information for identifying patients with impaired systolic function and diastolic dysfunction (pseudonormal or restrictive filling pattern), and for assessing the risk of cardiovascular death. Conclusions: Cardiac natriuretic peptides are useful tools for evaluating elderly patients with heart failure. Three of the 4 peptides were very similar. ANP exhibits inferior properties and cannot be recommended in clinical practice. © 2007 Elsevier Inc. All rights reserved.

    Health check-ups and family screening allow detection of hereditary hemochromatosis with less advanced liver fibrosis and survival comparable with the general population2011In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, Vol. 46, no 9, 1118-1126 p.Article in journal (Refereed)
    Abstract [en]

    Objective. The information concerning the morbidity and mortality of hereditary hemochromatosis is based primarily on clinical cohorts of symptomatic patients. The major aim of this study was to analyze the long-term prognosis for Swedish patients with this condition, with respect to both clinical features and survival, in relation to the route by which the disease was detected. Patients and methods. 373 patients with hemochromatosis detected through routine health checkups (n = 153), family screening (n = 44), symptoms of arthralgia (n = 23), investigation of other diseases/symptoms (n = 108) or signs of liver disease (n = 45) were monitored for a mean period of 11.9 +/- 5.8 years. The degree of liver fibrosis and survival were analyzed. Results. Overall survival among these patients was not significantly different from that of a matched normal population. The patients diagnosed through health check-ups and family screening were detected at an earlier age and had the highest rate of survival. Liver biopsy at the time of diagnosis revealed cirrhosis in 9% of those detected through the health check-ups and 5% in the case of family screening, compared with 13% for the group with arthralgia, 17% for other diseases/symptoms and 42% for liver disease. Conclusion. Health check-ups and family screening allow detection of hereditary hemochromatosis at an earlier age and with less advanced liver fibrosis, although a few of these patients have already developed cirrhosis. Our study indicates that iron indices should be included in health check-ups, and if abnormal, should lead to further investigation.

    Sickness absence with low-back, shoulder, or neck diagnoses: An 11-year follow-up regarding gender differences in sickness absence and disability pension2005In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, Vol. 25, no 2, 115-124 p.Article in journal (Refereed)
    Abstract [en]

    Background: There is very little knowledge on the long-term outcomes of sickness absence. The aim was to investigate sickness absence and disability pensions over 11 years in a cohort of young persons initially long-term sick listed with back, neck, or shoulder diagnoses.

    Method: A prospective population-based cohort study of all 213 individuals in the Municipality of Linköping, Sweden, who in 1985 were aged 25-34 and had at least one new sick-leave spell > 28 days with such diagnoses.

    Main results: More women (61%) than men fulfilled the inclusion criteria. In 1996, 22% of the cohort (14% of the men, 26% of the women) had been granted disability pension; 76% of these individuals with musculoskeletal and the rest with psychiatric diagnoses. Partial disability pension was granted to 59% of the women, 17% of the men. Women were more often granted temporary disability pension than men.

    Conclusions: This proved to be a high-risk group for disability pension. There were large and somewhat unexpected gender differences regarding incidence and type of disability pension. It has been debated how soon physicians should be concerned about the risk of long-term disability regarding these diagnoses; at four or eight weeks of sickness absence - our results support the former, at least for women.

    Epidemiology of sickness absence in a Swedish county in 1985, 1986 and 1987: A three year longitudinal study with focus on gender, age and occupation1994In: Scandinavian Journal of Social Medicine, ISSN 0300-8037, Vol. 22, no 1, 27-34 p.Article in journal (Refereed)
    Abstract [en]

    In order to get a better epidemiological base for preventive intervention in the county of Östergötland, Sweden, a comprehensive study of sickness absence was done. During the years 1985, 1986 and 1987, all new periods of sick-leave exceeding seven days were registered with demographic variables. This information was related to data about the total population of Östergötland. Each year approx. 45,000 persons had approx. 61,000 sickness spells. These figures were stable over the years while the number of sick-leave days increased. Blue-collar occupations had the highest sick-leave rates and the female sick-leave rate was higher in general and much higher in most male-dominated occupations. The male rate was lower within female-dominated areas, except among secretaries and textile workers. Females in extremely male-dominated groups had the highest rates, while both male and female sick-leave rates were lower in more gender-integrated occupations.

    Sickness absence in a Swedish county: with reference to gender, occupation, pregnancy and parenthood1995Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The occurrence of sickness absence in relation to gender, occupation, age, pregnancy and parenthood was analysed in a Swedish county. Data on all new sick-leave spells exceeding 7 days in the county of Östergötland (400,000 inhabitants) were recorded in 1985-1987. Information on diagnoses, occupation, age, gender, number of children etc. for each of the 45,000 persons sicklisted/year were included in the database. Incidence measures were obtained using census data as denominator.

    The largest and most consistent variation in occurrence of sickness absence concerned occupation and gender, When categorising the occupations according to degree of gender-segregation, women in the extremely maledominated group (>90% men) had exceptionally high sick-leave rates, while both men and women in the group of gender-integrated occupations had significantly lower sick-leave rates. These variations with male-and female domination of occupational groups were found for sickness absence in general as well as for sick-leave due to pregnancy-related diagnoses. Men with custody of young children had the lowest sickness absence, young women in the same situation the highest, while there were no gender differences in persons without young children. Sickness absence due to pregnancy-related diagnoses varied to a large degree with occupation, but was still high in occupations with a generally low sickness absence, and increased much more than in any otherdiagnostic group over the three years. About half of the gender differences in sickness absence could be explained by sickness absence among pregnant women.

    In conclusion, the occurrence of sickness absence was associated with gender, age, occupation, gender segregation of occupation, pregnancy and parenthood. Further research should focus on etiological studies and intervention trials.

    Management and Outcome in Non ST-Elevation Acute Coronary Syndromes: Similarities and Differences Between Women nad Men2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Non ST-elevation Acute Coronary Syndromes are the most frequent manifestations of acute ischemic heart disease. Gender differences in treatment intensity, including differences in level of care, have been reported. Also differences in benefit from certain treatments, especially invasive treatment, have been discussed. Finally, difference in outcome between men and women, have been proposed. Results have been inconsistent, partly depending on if and how adjustment for differences in background characteristics has been made. The aims of the studies in this thesis were to assess differences between the genders in baseline characteristics, level of care, medical treatment and non-invasive and invasive cardiac procedures. The aims were also to determine gender differences in short and long-term mortality, including impact of level of care, and to determine differences between the genders in benefit from an invasive strategy, with special reference to benefit in women.

    Method: We used prospectively collected data from the RIKS-HIA registry in two studies (Paper I and IV). In one study we merged data from patients admitted to general wards in the south-east region of Sweden (The AKUT registry), with data from patients admitted to CCU´s (RIKS-HIA) at participating hospitals during the same time (Paper II). We also randomly assigned women to a routine invasive or a selective invasive treatment strategy, and performed a meta-analysis, to determine gender differences in benefit from a routine invasive strategy (Paper III).

    Results: Women were older than men and more likely to have a history of diabetes and hypertension, while men were more likely to have a history of myocardial infarction and revascularisation. Women were also more likely to have normal coronary arteries on the angiogram. After adjustment for baseline differences there were only minor, and directionally inconsistent, differences between women and men in pharmacological treatment. Men were more often referred for coronary angiography, even after adjustment. While CABG-rate was lower in women, after adjustment PCI-rate was similar or even higher compared to men. After adjustment for differences in age, longterm outcome was better in women. In our small but randomised trial there was no benefit from a routine invasive strategy in women. A meta-analysis indicated interaction between gender and treatment strategy, with lack of benefit in women, in contrast to in men. However, our large observational study indicated no gender difference with an invasive strategy. Moreover, benefit was similar in women and men with invasive treatment.

    Conclusion: There are substantial differences between women and men in baseline characteristics that affect management and outcome more than gender per se. After adjustment women have better long-term outcome than men. There appear to be a difference in benefit from a routine invasive strategy between the genders, with less benefit in women, but in routine clinical management there was no difference between women and men managed with an invasive strategy.

    Impact of an invasive strategy on 5 years outcome in men and women with non-ST-segment elevation acute coronary syndromes2014In: American Heart Journal, ISSN 0002-8703, E-ISSN 1097-6744, Vol. 168, no 4, 522-529 p.Article in journal (Refereed)
    Abstract [en]

    Background A routine invasive (RI) strategy in non-ST-segment elevation acute coronary syndromes (NSTE ACS) has been associated with better outcome compared with a selective invasive (SI) strategy in men, but results in women have yielded disparate results. The aim of this study was to assess gender differences in long-term outcome with an SI compared with an RI strategy in NSTE ACS. Methods Individual patient data were obtained from the FRISC II trial, ICTUS trial, and RITA 3 trial for a collaborative meta-analysis. Results Men treated with an RI strategy had significantly lower rate of the primary outcome 5-year cardiovascular (CV) death/myocardial infarction (MI) compared with men treated with an SI strategy (15.6% vs 19.8%, P = .001); risk-adjusted hazards ratio (HR) 0.73 (95% CI 0.63-0.86). In contrast, there was little impact of an RI compared with an SI strategy on the primary outcome among women (16.5% vs 15.1%, P = .324); risk-adjusted HR 1.13 (95% CI 0.89-1.43), interaction P = .01. For the individual components of the primary outcome, a similar pattern was seen with lower rate of MI (adjusted HR 0.69, 95% CI 0.57-0.83) and CV death (adjusted HR 0.71, 95% CI 0.56-0.89) in men but without obvious difference in women in MI (adjusted HR 1.13, 95% CI 0.85-1.50) or CV death (adjusted HR 0.97, 95% CI 0.68-1.39). Conclusions In this meta-analysis comparing an SI and RI strategy, benefit from an RI strategy during long-term follow-up was confirmed in men. Conversely, in women, there was no evidence of benefit.

    Large early variation of residual platelet reactivity in Acute Coronary Syndrome patients treated with clopidogrel: Results from Assessing Platelet Activity in Coronary Heart Disease (APACHE).2015In: Thrombosis Research, ISSN 0049-3848, E-ISSN 1879-2472, Vol. 136, no 2, 335-340 p.Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: There is a large inter-individual variation in response to clopidogrel treatment and previous studies have indicated higher risk of thrombotic events in patients with high residual platelet reactivity (HRPR), but the optimal time-point for testing is not established. The aim of this study was to investigate the optimal time-point for aggregometry testing and the risk of major adverse cardiac events associated with HRPR.

    METHOD AND RESULTS: We included 125 patients with ACS (73 with STEMI, and 71 received abciximab). The prevalence of HRPR varied substantially over time. The rate of HRPR in patients treated and not treated with abciximab were 43% vs 67% (p=0.01) before, 2% vs 23% (p=0.001) 6-8h after, 8% vs 9% (p=0.749) 3days after, and 23% vs 12% (p=0.138) 7-9 days after loading dose of clopidogrel. We found HRPR in 18% of the patients but only four ischemic events during 6months follow-up, with no significant difference between HRPR patients compared to the rest of the population. There were 3 TIMI major bleedings, all of which occurred in the low residual platelet reactivity (LRPR) group.

    CONCLUSION: There is a large variation in platelet reactivity over time, also depending on adjunctive therapy, which has a large impact on optimal time-point for assessment. We found HRPR in almost 1 in 5 patients, but very few MACE, and not significantly higher in HRPR patients. In a contemporary ACS population, with low risk for stent thrombosis, the predictive value of HRPR for ischemic events will probably be low.

In the non-invasive strategy arm, the relative risk (RR) of death was (women vs. men) 1.02 [95% confidence interval (CI), 0.94-1.11] and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders, with propensity score and discharge medication, there was a similar trend towards better outcome among women in both the early non-invasive cohort [RR 0.90 (95% CI, 0.82-0.99)] and the early invasive cohort [RR 0.90 (95% CI, 0.76-1.06)], although it did not reach statistical significance in the early invasive cohort. Results were similar with the combined endpoint death/myocardial infarction. An early invasive treatment was associated with a marked, and similar, mortality reduction in women [RR 0.46 (95% CI, 0.38-0.55)] and men [RR 0.45 (95% CI, 0.40-0.52)], without interaction with gender. less thanbrgreater than less thanbrgreater thanConclusion In this large cohort of patients with NSTE ACS, reflecting real-life management, women and men had similar and better outcome associated with an invasive strategy.

    Although women are less likely to be admitted to coronary care units, they are treated equally to men and have better outcome: A prospective cohort study in patients with non ST-elevation acute coronary syndromes2009In: Acute cardiac care, ISSN 1748-295X, Vol. 11, no 3, 173-180 p.Article in journal (Refereed)
    Abstract [en]

    Background: The aim of this study was to assess gender differences in admission level of care, management and outcome in patients with non ST-elevation acute coronary syndromes (NSTE-ACS), initially admitted to either coronary care units (CCU) or general wards. Method: Patients admitted to CCUs were routinely registered in the RIKS-HIA registry. In addition, patients admitted to general wards with suspected ACS were also identified and registered. Multivariable regression analysis was used to adjust for baseline differences between the genders. Results: We included 570 consecutive patients with a discharge diagnosis of NSTE-ACS. Women were less likely to be admitted to coronary care units (56% versus 69%, P=0.002), even after adjustment (odds ratio (OR), 0.65; 95% confidence interval (CI): 0.43-0.98). After adjustment for differences in baseline characteristics, women were treated similarly to men. We found no significant differences in crude short-, or long-term mortality between the genders. However, adjustment for background characteristics revealed lower one-year mortality in women (OR: 0.58; 95% CI: 0.34-0.99). Conclusion: In this study on patients with NSTE-ACS, women were less likely to be admitted to coronary care units. However, the overall treatment was as intensive for women as for men. Moreover, after adjustment, one-year mortality was lower in women.

    Similar outcome with an invasive strategy in men and women with Non ST-Elevation Acute Coronary SyndromesManuscript (preprint) (Other academic)
    Abstract [en]

    Background: Gender differences in benefit from an early invasive strategy in patients with Non ST-elevation Acute Coronary Syndromes (NSTE ACS) have been debated and results are conflicting. Some studies have even indicated harm for women associated with a routine invasive strategy.

    Method: We included 46 455 patients ( 14 819 women (32%) and 31 636 men (68%)) from The Register of Information and Knowledge about Swedish Heart Intensive care Admissions (RIKS-HIA), with a diagnosis of either unstable angina pectoris or non-ST-elevation myocardial infarction. All patients were admitted to intensive coronary care units in Sweden, between 2000 and 2006, and followed for 1 year. Adjustment for baseline differences between the genders was made.

    Results: In the non-invasive strategy arm relative risk (RR) of death was (women vs. men) 1.02 (95% CI, 0.94-1.11) and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders with propensity score and discharge medication there was a trend towards lower mortality among women, RR 0.90 (95% CI, 0.82-0.99) in the early non-invasive group but still no difference in the early invasive cohort RR 0.90 (95% CI, 0.76-1.06). Results were similar with the combined end-point death/MI. The risk reduction with an invasive strategy was similar in women (RR 0.46 (95% CI 0.38-0.55)) and men (RR 0.45 (95% CI 0.40-0.52).

    Conclusion: In this large cohort of patients with NSTE ACS, reflecting real life management, women and men had similar outcome and similar benefit with an early invasive strategy.

    Gender differences in management and outcome in non-ST-elevation acute coronary syndrome2007In: Heart, ISSN 1355-6037, E-ISSN 1468-201X, Vol. 93, no 11, 1357-1362 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To study gender differences in management and outcome in patients with non-ST-elevation acute coronary syndrome. Design, setting and patients: Cohort study of 53 781 consecutive patients (37% women) from the Register of Information and Knowledge about Swedish Heart Intensive care Admissions (RIKS-HIA), with a diagnosis of either unstable angina pectoris or non-ST-elevation myocardial infarction. All patients were admitted to intensive coronary care units in Sweden, between 1998 and 2002, and followed for 1 year. Main outcome measures: Treatment intensity and in-hospital, 30-day and 1 -year mortality. Results: Women were older (73 vs 69 years, p<0.001) and more likely to have a history of hypertension and diabetes, but less likely to have a history of myocardial infarction or revascularisation. After adjustment, there were no major differences in acute pharmacological treatment or prophylactic medication at discharge. Revascularisation was, however, even after adjustment, performed more often in men (OR 1.15, 95% CI, 1.09 to 1.21). After adjustment, there was no significant difference in in-hospital (OR 1.03, 95% CI, 0.94 to 1.13) or 30-days (OR 1.07, 95% CI, 0.99 to 1.15) mortality, but at 1 year being male was associated with higher mortality (OR 1.12, 95% CI, 1.06 to 1.19). Conclusion: Although women are somewhat less intensively treated, especially regarding invasive procedures, after adjustment for differences in background characteristics, they have better long-term outcomes than men.

    Abstract [en]

    Acute Coronary Syndromes are the most frequent manifestations of coronary heart disease (CHD). Gender differences in treatment intensity, including differences in level of care, have been reported. Also differences in benefit from certain treatments, especially invasive treatment, have been discussed. Finally, differences in outcome between men and women have been proposed. Results have been inconsistent, partly depending on if and how adjustment for differences in background characteristics has been made.

    Går det att utveckla sitt professionella förhållningssätt gentemot klient?2009In: / [ed] Förbundet Sveriges Arbetsterapeuter, 2009Conference paper (Refereed)
    Abstract [sv]

    Bakgrund: Utifrån de nationella målen för Arbetsterapeutexamen skall studenter efter erlagd examen bl.a. visa förmåga till professionellt förhållningssätt gentemot klient, närstående eller andra grupper. Arbetsterapeutprogrammet, HU, LiU, består av totalt 12 kurser. Vid den senaste kursplaneförändringen infördes bl.a. tre kurser med stark fokus på arbetsterapeutens yrkesutövning och professionellt förhållningssätt. The Intentional Relationship Model (IRM) (Taylor, 2008) används som ett sätt att medvetet arbeta för att utveckla förmåga till ett professionellt förhållningssätt.

    Syftet är att undersöka hur studenter under sin studietid vid Arbetsterapeutprogrammet, HU, LiU, utvecklar sitt professionella förhållningssätt i mötet med klienter.

    Metod: Vid tre tillfällen under utbildningen, initialt, i mitten och i slutet, fyller studenter i ett självskattningsformulär (Taylor, 2008) angående förhållningssätt de skulle kunna använda i olika exemplifierade klientkontakter. IRM presenteras samt sex förhållningssätt enligt IRM, och studenterna arbetar vidare med dessa förhållningssätt genom olika lärmoment, som basgrupp och praktiska moment.

    Förväntat resultat: Att studenterna har utvecklat och reflekterat över sitt professionella förhållningssätt under utbildningen och därmed kan visa en förmåga till professionellt förhållningssätt.

    Konklusion: Användandet av IRM kan vara ett sätt att medvetet utveckla professionellt förhållningssätt hos såväl arbetsterapeutstudenter som yrkesverksamma arbetsterapeuter.

    Medvetna relationer skapar bra interventioner2012In: Arbetsterapeuten, ISSN 0345-0988, no 3, 32-33 p.Article in journal (Other academic)
    Abstract [sv]

    IRM är utvecklad av professor Renée Taylor, som är doktor i klinisk psykologi och professor i arbetsterapi vid University of Illinois i Chicago. Modellen beskrivs i hennes bok från 2008 The Intentional Relationship – Occupational Therapy and Use of Self. Syftet med modellen är att erbjuda en specifik begreppsapparat för ett medvetet användande av sig själv som arbetsterapeut och den behandlar händelser som förekommer i relationer mellan personer i en interventionsprocess. Dessa händelser påverkar såväl aktivitetsengagemang som utfall av intervention.

    Utilization and content validity of the Swedish version of the Volitional Questionnaire (VQ-S)2008In: Occupational Therapy in Health Care, ISSN 0738-0577, E-ISSN 1541-3098, Vol. 22, no 2-3, 163-176 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to examine the utility and content validity of the Swedish version of the Volitional Questionnaire (VQ-S). The participants in this study were thirteen occupational therapists selected because they worked with clients for whom the VQ-S is appropriate (in this case, adults with intellectual impairments) and because they had knowledge of the Model of Human Occupation. These participants completed a demographic questionnaire at the beginning of the study. Each therapist then used the VQ-S a total of six times and after each time they completed a questionnaire concerning the utility and content validity of the instrument. After having administered the instrument six times they completed a third questionnaire that assessed their perceptions of the VQ-S based on their total experience. Data from these questionnaires and the six assessment forms with the actual client ratings were analyzed using both quantitative and qualitative procedures. The findings indicate that the VQ-S has clinical relevance and potential for implementation with adults with intellectual impairments. They also support the content validity of the VQ-S.

    Low-level cadmium exposure and osteoporosis.2000In: Journal of Bone and Mineral Research, ISSN 0884-0431, Vol. 15, 1579-1586 p.Article in journal (Refereed)
    Abstract [en]

    Osteoporosis is a major cause of morbidity worldwide. A number of risk factors, such as age and gender, are well established. High cadmium exposure causes renal damage and in severe cases also causes osteoporosis and osteomalacia, We have examined whether long-term Pow-level cadmium exposure increases the risk of osteoporosis. Bone mineral density (BMD) in the forearm was measured in 520 men and 544 women, aged 16-81 years, environmentally or occupationally exposed to cadmium, using dual-energy X-ray absorptiometry (DXA) technique. Cadmium in urine was used as the dose estimate and protein HC was used: as a marker of renal tubular damage. There was a clear dose-response relation between cadmium dose and the prevalence of tubular proteinuria. Inverse relations were found between cadmium dose, tubular proteinuria, and BMD, particularly apparent in persons over 60 years of age, There was a dose-response relation between cadmium dose and osteoporosis. The odds ratios (ORs) for men were 2.2 (95% CI, 1.0-4.8) in the dose group 0.5-3 nmol Cd/mmol creatinine and 5.3 (2.0-14) in the highest dose category (greater than or equal to 3 nmol/mmol creatinine) compared with the lowest dose group (<0.5 nmol Cd/mmol creatinine). For women, the OR was 1.8 (0.65-5.3) in the dose group 0.53 nmol Cd/mmol creatinine. We conclude that exposure to low levels of cadmium is associated with an increased risk of osteoporosis.

    Comorbid insomnia in patients with chronic pain: a study based on the Swedish quality registry for pain rehabilitation (SQRP)2014In: Disability and Rehabilitation, ISSN 0963-8288, E-ISSN 1464-5165, Vol. 36, no 20, 1661-1669 p.Article in journal (Refereed)
    Abstract [en]

    Purpose: This study investigates the prevalence of insomnia and its relationship to other symptoms and health aspects in patients with chronic pain. Methods: Patients with chronic pain conditions (n = 845) referred to a multidisciplinary pain centre completed surveys provided by the Swedish quality registry for pain rehabilitation (SQRP). The SQRP collects data on socio-demographics, health status, symptoms of pain, mood and insomnia and life satisfaction. Results: The majority of patients (65.3%) had clinical insomnia according to the insomnia severity index (ISI). Insomnia correlated significantly but weakly with pain, depression, anxiety and coping; the strongest multivariate correlations were found with depression and anxiety followed by pain interference and pain severity. Pain intensity, depression and anxiety correlated stronger than ISI with respect to the two investigated aspects of health. Conclusions: The prevalence of insomnia is high in patients with chronic pain conditions, but the level of importance in relation to other symptoms for health aspects is low, and the associations with other important symptoms are relatively weak. One way to increase the effects of multimodal rehabilitation programs may be to provide interventions directed specifically at insomnia rather than focusing only on interventions that address pain, depression and anxiety. Implications for Rehabilitation The prevalence of insomnia is high in patients with complex chronic pain conditions. Relatively low correlations existed between insomnia and pain intensity, depression, anxiety and other psychological aspects. Pain intensity, anxiety and depression were more important for perceived health aspects than insomnia. One way to increase the effects of multimodal rehabilitation programs may be to also include interventions directed directly to insomnia.
