Responsiveness of the International Classification of Functioning, Disability and Health (ICF) Core Set for rheumatoid arthritis

Background: The comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set for rheumatoid arthritis (RA) is a selection of 96 categories from the ICF, representing relevant aspects in the functioning of patients with RA. Objectives: To study the responsiveness of the ICF Core Set for RA in rheumatological practice. Methods: A total of 46 patients with RA (72% women, mean (SD) age 53.6 (12.6) years, disease duration 6.3 (8.0) years) were interviewed at baseline and again after 6 months treatment with a disease-modifying antirheumatic drug (DMARD), applying the ICF Core Set for RA with qualifiers for problems on a modified three-point scale (no problem, mild/moderate, severe/complete). Patient-reported outcomes included Modified Health Assessment Questionnaire (MHAQ) and Short-Form 36 (SF-36) health survey, and disease activity was calculated. Responsiveness was measured as change in qualifiers in ICF categories, and was also compared with change in patient-reported outcomes. Results: After 6 months of DMARD treatment, improvement by at least one qualifier was seen in 20% of patients (averaged across all ICF categories), 71% experienced no change and 9% experienced worsening symptoms. Findings were similar across the different aspects of functioning. Mainly moderate effect sizes were seen for 6-month changes in the ICF Core Set for RA, especially in patients with improved health status, with similar effect size for disease activity. The components in the ICF Core Set for RA were only weakly associated with patient-reported outcomes and disease activity. Conclusions: The ICF Core Set for RA demonstrated moderate responsiveness in this real-life setting of patients where minor changes occurred during treatment with DMARDs

Dynamics of Electron Localization in Warm vs. Cold Water Clusters

The process of electron localization on a cluster of 32 water molecules at 20, 50, and 300~K is unraveled using ab initio molecular dynamics simulations. In warm, liquid clusters, the excess electron relaxes from an initial diffuse and weakly bound structure to an equilibrated, strongly bound species within 1.5 ps. In contrast, on cold, glassy clusters the relaxation processes is not completed and the electron becomes trapped in a metastable surface state with an intermediate binding energy. These results question the validity of extrapolations of the properties of solvated electrons from cold clusters of increasing size to the liquid bulk

Quadricuspid pulmonary valve complicated with aneurysm of pulmonary trunk diagnosed with ECG-gated computed tomography

Quadricuspid pulmonary valve (QPV) is an uncommon congenital defect reported in the general population with a frequency of up to 0.25%. The defect usually does not cause severe clinical complications and its presence frequently remains clinically silent. Moreover, there are several difficulties in visualization of pulmonary valve using basic diagnostic modalities such as echocardiography. Therefore, in the majority of cases, QPV is detected accidentally during cardiac procedures or post mortem. The authors present a case of QPV complicated with aneurysm of the pulmonary trunk, diagnosed with computed tomography in 70-year-old woman. Although the patient had undergone transthoracic echocardiography examinations several times in the past, only computed tomography allowed the detection of the anomalous valve. In addition, the examination confirmed aneurysm of the pulmonary trunk. To the best of our knowledge, this is the first case of QPV diagnosed in vivo with computed tomography
