    We investigated the effect of ego depletion on risk taking. Specifically, we conducted three studies (total n= 1,716) to test the prediction that ego depletion results in decisions that are more strongly in line with prospect theory, i.e., that ego depletion reduces risk taking for gains, increases risk taking for losses, and increases loss aversion. Ego depletion was induced using two of the most common manipulations from previous literature: the letter e task (Studies 1 and 3) and the Stroop task (Study 2). Risk taking was measured using a series of standard, incentivized economic decision-making tasks assessing risk preferences in the gain domain, risk preferences in the loss domain, and loss aversion. None of the studies revealed a significant effect of ego depletion on risk taking. Our findings cast further doubts about the ability of ego-depletion manipulations to affect actual behavior in experimental settings.Funding Agencies|Swedish Research Council [2019-00849]; Marianne and Marcus Wallenberg Foundation [2014.0187]</p

    Utility of a simplified ultrasound assessment to assess interstitial pulmonary fibrosis in connective tissue disorders - preliminary results

    Get PDF
    Interstitial pulmonary fibrosis (IPF) is a frequent manifestation in patients with connective tissue disorders (CTD). Recently the ultrasound (US) criterion validity for its assessment has been proposed; however, the US scoring systems adopted include the study of several lung intercostal spaces (LIS), which could be time-consuming in daily clinical practice. The aim of this study was to investigate the utility of a simplified US B-lines scoring system compared with both the US comprehensive assessment and the high-resolution computed tomography (HRCT) findings of IPF in CTD patients. METHODS:Thirty-six patients with a diagnosis of CTD were enrolled. Each patient underwent chest HRCT and lung US by an experienced radiologist and rheumatologist, respectively. Both comprehensive and simplified US B-lines assessments were scanned. The comprehensive US assessment was performed at 50 LIS level, whereas the simplified US assessment included bilaterally 14 LIS; for the anterior chest: the second LIS along the para-sternal lines, the fourth LIS along the mid-clavear, anterior axillary and mid-axillary lines; for the posterior chest: the eighth LIS along the paravertebral, sub-scapular and posterior axillary lines. For criterion validity, HRCT was considered the gold standard. Feasibility, inter and intra-observer reliability was also investigated. RESULTS: A highly significant correlation between comprehensive and simplified US assessment was found (P = 0.0001). A significant correlation was also found between the simplified US assessment and HRCT findings (P = 0.0006). Kappa values for the inter-observer simplified US assessment were in a range from 0.769 to 0.885, whereas the concordance correlation coefficient values for the intra-observer were from 0.856 to 0.955. There was a relevant difference in time spent on comprehensive (mean 23.3 ± SD 4.5 minutes) with respect to the simplified US assessment (mean 8.6 ± SD 1.4) (P < 0.00001). CONCLUSIONS:Our results provide a new working hypothesis in favor of the utility of a simplified US B-lines assessment as an adjunct method to assess IPF in patients with CTD

    ABSTRACT. Objective. Vertebral fractures are a common complication of osteoporosis and may have a negative effect on health-related quality of life (HRQOL). We investigated the effect of prevalent vertebral fractures on HRQOL in patients with osteoporosis. Methods. A cross-sectional multicenter study was carried out among postmenopausal women with primary osteoporosis attending primary care centers and hospital outpatient clinics: 234 women with vertebral fractures and 244 asymptomatic women. Women with secondary osteoporosis or taking medications that affect bone metabolism were excluded. All patients were questioned using the miniOsteoporosis Quality of Life Questionnaire (mini-OQLQ), Medical Outcomes Study Short , and the EuroQuol-5D, after assessment of all clinical variables and anthropometric data. To assess comorbidity we used the Self-Administered Comorbidity Questionnaire (SCQ). Diagnosis of osteoporosis was confirmed in all patients by bone mineral density using dual energy x-ray absorptiometry. Radiographic evaluation was performed by a musculoskeletal radiologist. A total of 483 postmenopausal women, randomly matched for age out of 1579 healthy controls, were chosen to compare the SF-36 scores with respect to patients with and without vertebral fractures due to osteoporosis. A multivariable regression analysis was conducted to identify the strongest determinant for low HRQOL, adjusted for potential confounding variables such as comorbid conditions, education level, and psychosocial status. Results. The vertebral fracture group had significantly lower scores than patients without fractures and controls in all domains of the generic and specific questionnaires. Women with only 1 prevalent fracture had statistically significantly lower HRQOL scores than those without fractures on SF-36 measures of bodily pain, physical functioning, and role function physical (all p &lt; 0.01). HRQOL scores were lower in women with lumbar fractures compared with women with thoracic fractures only when the physical functioning and bodily pain dimensions approached statistical significance. Based on the multivariate analysis, the strongest determinant for low HRQOL was physical functioning (explained by number of vertebral fractures) followed by comorbidity score and age. Adjusted R 2 in the final model was 35.9%. Using the SF-36 summary scales, comorbid conditions predominantly affected either mental or physical health (p &lt; 0.0001). A significant correlation (p &lt; 0.0001) was found between total score on the mini-OQLQ and the mean SCQ comorbidity score. Conclusion MATERIALS AND METHODS Recruitment of patients. In this cross-sectional multicenter study we investigated 478 postmenopausal women (mean age 68.5 yrs, range 48-89 yrs) with primary clinically stable osteoporosis (no change in treatment and no new clinical deformities in the last 12 mo) attending primary care centers and hospital outpatient clinics. The patient group included 234 women (mean age 69 yrs, range 48-89) who had vertebral fractures due to osteoporosis, and a group of 244 asymptomatic osteoporotic women matched for age with the patients with vertebral fractures. The women were screened in 5 rheumatology centers in Northern and Central Italy. A simple algorithm, the OPERA 23 , based on age, weight, history of previous low impact fracture, early menopause, and corticosteroid therapy, was used as a prescreening tool to help clinicians identify which women are at increased risk for osteoporosis. Diagnosis of osteoporosis was confirmed by bone mineral density (BMD) using dual-energy x-ray absorptiometry (DEXA). Osteoporosis was defined as a T score lower than -2.5 (the difference between the measured BMD and the mean value of young adults, expressed in standard deviations), according to the World Health Organization Study Group definition 24 . All measurements at the left femoral neck and lumbar spine (L1-L4), in the anteroposterior position, were obtained using the Hologic scanner (Hologic QDR 4500; Hologic, Bedford, MA, USA). One of the inevitable limitations of the study was the use of different densitometry machines, yielding noncomparable BMD data. Thus, machines at each participating center were cross-calibrated at the beginning of the study using the same spine phantom (supplied by the manufacturer). Each phantom was scanned 10 times at each study center. Quality control procedures were followed according to the manufacturer&apos;s recommendations. T scores were based on a large European and US reference database for BMD 25 . Radiographic evaluation was performed centrally (at the Department of Radiology of the UniversitĂ  Politecnica delle Marche) by an experienced musculoskeletal radiologist. Total spine radiographs in lateral standing views in neutral/flexion/extension and in the lateral decubitus position in flexion/extension were taken with a film-tube distance of 1.8 m. The anterior, central, and posterior heights of each of the vertebral bodies from T4 to L5 in a neutral standing radiograph were measured using calipers. Vertebral fracture was considered present if at least one of 3 height measurements (anterior, middle, posterior) of one vertebra had decreased by more than 20% compared with the height of the nearest uncompressed vertebral body Further, 483 postmenopausal women (mean age 69.1 yrs, range 50-87) randomly matched for age out of 1579 healthy controls were chosen for comparison of SF-36 scores of patients with and without vertebral fractures due to osteoporosis. Subjects with fibromyalgia, chronic back pain, and vertebral or other fractures were excluded. As acquisition of radiographs in the control group study was considered unethical in the context of the study, inclusion in this group depended on oral confirmation that the individual had never 1552 The received a clinical diagnosis of vertebral or other fracture. This sample was selected from a previous cross-sectional population-based study, the MAP-PING (MArche Pain Prevalence INvestigation Group) study Background and illness-related variables. Demographic and socioeconomic information was assessed from patient interviews. Education level was separated into 3 categories based on the Italian school system: 1 = primary school, 2 = secondary school, and 3 = high school or university. The body mass index (BMI, body weight/height 2 ) was used to assess overweight. In all patients the presence of comorbidities was also assessed through patient self-reports using the Self-Administered Comorbidity Questionnaire (SCQ) 28 , a modification of the widely used Charlson Index 29 . The SCQ uses patient interview or questionnaire responses rather than chart abstraction for assessment of comorbidity and is in excellent agreement with the chart-based Charlson Index 28 . We evaluated the rate of endorsement of each of 12 specific conditions as well as the number of conditions endorsed. We also calculated a score with 1 point if the condition was endorsed and additional points if the subject reported currently receiving treatment for it, or if it limited activities. Each condition could, therefore, contribute 0 to 3 points for a maximum of 36 points

    Diffuse idiopathic skeletal hyperostosis: a review

    Get PDF
    Coined in 1975 by Resnick et al., diffuse idiopathic skeletal hyperostosis describes a systemic condition that is mainly characterized by flowing ossification of the spine and, less frequently, peripheral entheses. Its overall incidence is 6-12%, but it is more frequently observed in males than in females and subjects aged >50 years, and its increased prevalence in people aged >70 years suggests that the course of the disease begins between the third and fifth decade of life but its clinical manifestations do not appear until later. Its pathogenesis and etiology remain unknown, but it has been reported to be associated with a number of genetic, metabolic, and constitutional factors. The aim of this review is to describe the main features of the disease and stimulate research into its pathogenesis, prevention, and treatment

    Salivary Gland Ultrasonography in Sjögren’s Syndrome: A European Multicenter Reliability Exercise for the HarmonicSS Project

    Get PDF
    Objectives: Salivary gland ultrasonography (SGUS) is increasingly applied for the management of primary Sjögren's syndrome (pSS). This study aims to: (i) compare the reliability between two SGUS scores; (ii) test the reliability among sonographers with different levels of experience. Methods: In the reliability exercise, two four-grade semi-quantitative SGUS scoring systems, namely De Vita et al. and OMERACT, were tested. The sonographers involved in work-package 7 of the HarmonicSS project from nine countries in Europe were invited to participate. Different levels of sonographers were identified on the basis of their SGUS experience and of the knowledge of the tested scores. A dedicated atlas was used as support for SGUS scoring. Results: Twenty sonographers participated in the two rounds of the reliability exercise. The intra-rater reliability for both scores was almost perfect, with a Light's kappa of 0.86 for the De Vita et al. score and 0.87 for the OMERACT score. The inter-rater reliability for the De Vita et al. and the OMERACT score was substantial with Light's Kappa of 0.75 and 0.77, respectively. Furthermore, no significant difference was noticed among sonographers with different levels of experience. Conclusion: The two tested SGUS scores are reliable for the evaluation of major salivary glands in pSS, and even less-expert sonographers could be reliable if adequately instructed.publishedVersio

    Relationship between time-integrated disease activity estimated by DAS28-CRP and radiographic progression of anatomical damage in patients with early rheumatoid arthritis

    <p>Abstract</p> <p>Background</p> <p>The main aim of the study was to investigate the relationship between persistent disease activity and radiographic progression of joint damage in early rheumatoid arthritis (ERA).</p> <p>Methods</p> <p>Forty-eight patients with active ERA was assessed every 3 months for disease activity for 3 years. Radiographic damage was measured by the Sharp/van der Heijde method (SHS). The cumulative inflammatory burden was estimated by the time-integrated values (area under the curve-AUC) of Disease Activity Score 28 joint based on C-reactive protein (DAS28-CRP) in rapid progressors versus non-progressors. Bland and Altman's 95% limits of agreement method were used to estimate the smallest detectable difference (SDD) of radiographic progression. The relationship between clinical and laboratory predictors of radiographic progression and their interactions with time was analysed by logistic regression model.</p> <p>Results</p> <p>After 3-years of follow-up, radiographic progression was observed in 54.2% (95%CI: 39.8% to 67.5%) of patients and SDD was 9.5 for total SHS. The percentage of patients with erosive disease increased from 33.3% at baseline to 76% at 36 months. The total SHS of the progressors worsened from a median (interquartile range) of 18.5 (15-20) at baseline to 38.5 (34-42) after 3 years (p < 0.0001) whereas non-progressors worsened from a median of 14.5 (13-20) at baseline to 22.5 (20-30) after 3 years (p < 0.001). In the regression model, time-integrated values of DAS28-CRP and anti-CCP positivity have the highest positive predictive value for progression (both at level of p < 0.0001). Radiographic progression was also predicted by a positive IgM-RF (p0.0009), and a high baseline joint damage (p = 0.0044).</p> <p>Conclusions</p> <p>These data indicate that the level of disease activity, as measured by time-integrated DAS28-CRP, anti-CCP and IgM-RF positivity and a high baseline joint damage, affects subsequent progression of radiographic damage in ERA.</p

    Reliability assessment of ultrasound muscle echogenicity in patients with rheumatic diseases: Results of a multicenter international web-based study

    ObjectivesTo investigate the inter/intra-reliability of ultrasound (US) muscle echogenicity in patients with rheumatic diseases.MethodsForty-two rheumatologists and 2 radiologists from 13 countries were asked to assess US muscle echogenicity of quadriceps muscle in 80 static images and 20 clips from 64 patients with different rheumatic diseases and 8 healthy subjects. Two visual scales were evaluated, a visual semi-quantitative scale (0–3) and a continuous quantitative measurement (“VAS echogenicity,” 0–100). The same assessment was repeated to calculate intra-observer reliability. US muscle echogenicity was also calculated by an independent research assistant using a software for the analysis of scientific images (ImageJ). Inter and intra reliabilities were assessed by means of prevalence-adjusted bias-adjusted Kappa (PABAK), intraclass correlation coefficient (ICC) and correlations through Kendall’s Tau and Pearson’s Rho coefficients.ResultsThe semi-quantitative scale showed a moderate inter-reliability [PABAK = 0.58 (0.57–0.59)] and a substantial intra-reliability [PABAK = 0.71 (0.68–0.73)]. The lowest inter and intra-reliability results were obtained for the intermediate grades (i.e., grade 1 and 2) of the semi-quantitative scale. “VAS echogenicity” showed a high reliability both in the inter-observer [ICC = 0.80 (0.75–0.85)] and intra-observer [ICC = 0.88 (0.88–0.89)] evaluations. A substantial association was found between the participants assessment of the semi-quantitative scale and “VAS echogenicity” [ICC = 0.52 (0.50–0.54)]. The correlation between these two visual scales and ImageJ analysis was high (tau = 0.76 and rho = 0.89, respectively).ConclusionThe results of this large, multicenter study highlighted the overall good inter and intra-reliability of the US assessment of muscle echogenicity in patients with different rheumatic diseases
