Patient-reported causes of heart failure in a large European sample
Background: Patients diagnosed with chronic diseases develop perceptions about their disease and its causes, which may influence health behavior and emotional well-being. This is the first study to examine patient-reported causes and their correlates in patients with heart failure. Methods: European heart failure patients (N = 595) completed questionnaires, including the Brief Illness Perceptions Questionnaire. Using deductive thematic analysis, patient-reported causes were categorized into physical, natural, behavioral, psychosocial, supernatural and other. Clinical data were collected from medical records. Results: Patients who did not report any cause (11%) were on average lower educated and participated less often in cardiac rehabilitation. The majority of the remaining patients reported physical causes (46%, mainly comorbidities), followed by behavioral (38%, mainly smoking), psychosocial (35%, mainly (work-related) stress), and natural causes (32%, mainly heredity). There were socio-demographic, clinical and psychological group differences between the various categories, and large discrepancies between prevalence of physical risk factors according to medical records and patient-reported causes; e.g. 58% had hypertension, while only 5% reported this as a cause. Multivariable analyses indicated trends towards associations between physical causes and poor health status (Odds ratio (OR) = 1.41, 95% confidence interval (95% CI) = 0.95-2.09, p = 0.09), psychosocial causes and psychological distress (OR = 1.54, 95% CI = 0.94-2.51, p = 0.09), and behavioral causes and a less threatening view of heart failure (OR = 0.64, 95% CI = 0.40-1.01, p = 0.06). Conclusion: European patients most frequently reported comorbidities, smoking, stress, and heredity as heart failure causes, but their causal understanding may be limited. There were trends towards associations between patient-reported causes and health status, psychological distress, and illness perceptions
Tumor necrosis factor inhibitor therapy but not standard therapy is associated with resolution of erosion in the sacroiliac joints of patients with axial spondyloarthritis
INTRODUCTION: Radiography is an unreliable and insensitive tool for the assessment of structural lesions in the sacroiliac joints (SIJ). Magnetic resonance imaging (MRI) detects a wider spectrum of structural lesions but has undergone minimal validation in prospective studies. The Spondyloarthritis Research Consortium of Canada (SPARCC) MRI Sacroiliac Joint (SIJ) Structural Score (SSS) assesses a spectrum of structural lesions (erosion, fat metaplasia, backfill, ankylosis) and its potential to discriminate between therapies requires evaluation. METHODS: The SSS score assesses five consecutive coronal slices through the cartilaginous portion of the joint on T1-weighted sequences starting from the transitional slice between cartilaginous and ligamentous portions of the joint. Lesions are scored dichotomously (present/absent) in SIJ quadrants (fat metaplasia, erosion) or halves (backfill, ankylosis). Two readers independently scored 147 pairs (baseline, 2 years) of scans from a prospective cohort of patients with SpA who received either standard (n = 69) or tumor necrosis factor alpha (TNFα) inhibitor (n = 78) therapy. Smallest detectable change (SDC) was calculated using analysis of variance (ANOVA), discrimination was assessed using Guyatt’s effect size, and treatment group differences were assessed using t-tests and the Mann–Whitney test. We identified baseline demographic and structural damage variables associated with change in SSS score by univariate analysis and analyzed the effect of treatment by multivariate stepwise regression adjusted for severity of baseline structural damage and demographic variables. RESULTS: A significant increase in mean SSS score for fat metaplasia (P = 0.017) and decrease in mean SSS score for erosion (P = 0.017) was noted in anti-TNFα treated patients compared to those on standard therapy. Effect size for this change in SSS fat metaplasia and erosion score was moderate (0.5 and 0.6, respectively). Treatment and baseline SSS score for erosion were independently associated with change in SSS erosion score (β = 1.75, P = 0.003 and β = 0.40, P < 0.0001, respectively). Change in ASDAS (β = −0.46, P = 0.006), SPARCC MRI SIJ inflammation (β = −0.077, P = 0.019), and baseline SSS score for fat metaplasia (β = 0.085, P = 0.034) were independently associated with new fat metaplasia. CONCLUSION: The SPARCC SSS method for assessment of structural lesions has discriminative capacity in demonstrating significantly greater reduction in erosion and new fat metaplasia in patients receiving anti-TNFα therapy

Symptoms associated with an abnormal echocardiogram in elderly primary care hypertension patients
Background The prevalence and diagnostic value of heart failure symptoms in elderly primary care patients with hypertension is unknown. Aim To assess the prevalence, sensitivity, specificity, positive and negative predictive value of symptoms in association with an abnormal echocardiogram. Design and setting Cross-sectional screening study in five general practices in the south-east of the Netherlands. Method Between June 2010 and January 2013, 591 primary care hypertension patients aged between 60 and 85 years were included, without known heart failure and not treated by a cardiologist. All patients underwent an echocardiogram and a structured interview including assessment of heart failure symptoms: shortness of breath, fatigue, oedema, cold extremities, and restless sleep. Results and conclusion Restless sleep was reported by 25 %, cold extremities by 23%, fatigue by 19 %, shortness of breath by 17 %, and oedema by 13 %. Oedema was the only symptom significantly associated with an abnormal echocardiogram (positive predictive value was 45 %, sensitivity 20 %, and specificity 90 %, OR 2.12; 95 % CI=1.23-3.64), apart from higher age (OR 1.06; 95 % CI=1.03-1.09), previous myocardial infarction (OR 3.00; 95 % CI=1.28-7.03), and a systolic blood pressure of >160 mmHg (OR 1.62; 95 % CI= 1.08-2.41). Screening with echocardiography might be considered in patients with oedema

Shock and patient preimplantation type D personality are associated with poor health status in patients with implantable cardioverter-defibrillator
Background: Implantable cardioverter-defibrillator (ICD) shock is a critical event to patients associated with well-being after implantation, although other factors may play an equally important role. We compared the association of shock and the patient's preimplantation personality with health status, using a prospective study design.
Methods and Results: Consecutively implanted ICD patients (n=383; 79% men) completed the Type D Scale at baseline and the Short-Form Health Survey 36 (SF-36) at baseline and 3, 6, and 12 months. Of all patients, 23.5% had a Type D personality and 13.8% received a shock during follow-up. Shocked patients reported significantly poorer health status, as did Type D patients. Health status patterns were poorest in patients with combined Type D personality and shock during follow-up. Shock during follow-up was a significant independent associate of poorer health status for 4 of 8 subscales of the SF-36 and the Mental Component Summary (all P<.05), with shocked patients scoring between 2.60 to 13.30 points lower than nonshocked patients. Type D personality was an independent associate of poor postimplantation health status for 6 of 8 of the SF-36 subscales and the Mental Component Summary, with Type D patients scoring between 2.12 to 8.02 points lower, adjusting for demographic and clinical characteristics.
Conclusions: ICD shock and the patient's preimplantation personality disposition were equally important associates of health status 12 months after implantation. Identification of the patient's personality profile before ICD implantation may help identify subsets of patients who may need additional care, for example, with a psychosocial component
Soil health and local recirculation ensuring organic cucumber cultivation in Norway.
New European organic regulation claims cultivation directly in soil in greenhouses. Cultivation practises in accordance with organic principles imply application of sustainable growing media and compost added for soil improvement. Local resources may be preferred. The goal of soil improvement is good soil health, including biological soil activity, nutrient availability, and physical properties. Only a few studies are done on biological soil health in greenhouses.
Biological soil activity was monitored in a greenhouse cucumber experiment on organic soil enriched with biochar and addition of local (1) compost, (2) solid digestate after biogas or (3) imported organic peat. Effects of silage mulching was tested. Biological activity was measured in soil by different indicators, and above soil, plant growth was followed.
Results indicated that the mixture with compost contained more organic matter than mixtures with solid digestate and peat. Biological activity in the compost mixture was lower and started later than in the two other mixtures and was in all mixtures more pronounced where silage mulch was added. Respiration rates and fungi content classified all three mixtures as stable growth media.
Nitrogen content and pH in all three mixtures were similar at the start of the experiment. The peat mixture needed most amendments, while phosphorous content was highest in solid digestate and lowest in peat. Plant nutrient turnover to plants was appropriate except lack of micronutrients. Yields performed well.
Preliminary conclusion is that although compost is based on microbial activity and taken for a protagonist in soil health, the results showed lower biological activity that started later than in the other mixtures. Balance between fungi and bacteria were in all three mixtures similar and equal to measurements in Norwegian, organic managed soil. Indicators were useful on farm level but could be diversified more. Local compost and digestate functioned as good as peat
