Activity of Daily Living Performance amongst Danish Asylum Seekers: A cross-sectional study
Objective: The aim of this study was to evaluate the extent of Activities of Daily Living (ADL) ability impairment in newly arrived Danish asylum seekers. It was hypothesized that exposure to trauma and torture would negatively influence ADL performance and that measures of ADL ability would be lower in individuals exposed to torture as compared to the non-tortured. Subjects: Forty-three newly arrived asylum seekers aged 20-50 years, from Iran, Afghanistan, and Syria, were consecutively included in the study.
Method: ADL ability was assessed with the observation-based test Assessment of Motor and Process Skills (AMPS). Interviews were based on questionnaires about torture exposure, WHO-5 Wellbeing Index, Major Depression Inventory and Pain Detect Questionnaire. All participants were interviewed and tested using a linguistic interpreter. Results: Thirty-three (77%) participants reported exposure to torture. The tortured did not differ significantly from the non-tortured on measures of ADL ability (two-sample t-tests: Motor, p= 0.36; Process, p= 0.82). ADL performance impairment was observed in the overall study sample. Twelve had motor and 15 process ability measures below age norms and 2 below both AMPS motor and process cut-offs for effortless and efficient ADL performance. There were statistically significant - weak to moderate - correlations between self-reported psychological distress, VAS average pain, pain distribution, and the AMPS measures. Conclusion: The study results supported significant ADL ability impairment in tortured as well as non-tortured newly arrived asylum seekers. Implementation of performance-based evaluation of ADL ability as part of the initial medical screening of this particular population should be considered
Rheumatoid Factor and Its Interference with Cytokine Measurements: Problems and Solutions
Use of cytokines as biomarkers for disease is getting more widespread. Cytokines are conveniently determined by immunoassay, but interference from present antibodies is known to cause problems. In rheumatoid arthritis (RA), interference of rheumatoid factor (RF) may be problematic. RF covers a group of autoantibodies from immunoglobulin subclasses and is present in 65–80% of RA patients. Partly removal of RF is possible by precipitation.
This study aims at determining the effects of presence of RF in blood and synovial fluid on cytokine measurements in samples from RA patients and finding possible solutions for recognized problems. IL-1β, IL-4, IL-6, and IL-8 were determined with multiplex immunoassays (MIA) in samples from RA patients prior to and after polyethylene glycol (PEG 6000) precipitation. Presence of RF does interfere with MIA. PEG 6000 precipitation abolishes this RF interference. We recommend PEG precipitation for all immunoassay measurements of plasma samples from RA patients
Test-retest of computerized health status questionnaires frequently used in the monitoring of knee osteoarthritis: a randomized crossover trial
<p>Abstract</p> <p>Background</p> <p>To compare data based on touch screen to data based on traditional paper versions of questionnaires frequently used to examine patient reported outcomes in knee osteoarthritis patients and to examine the impact of patient characteristics on this comparison</p> <p>Methods</p> <p>Participants were recruited from an ongoing trial (<url>http://ClinicalTrials.Gov</url> Identifier: <a href="http://www.clinicaltrials.gov/ct2/show/NCT00655941">NCT00655941</a>). 20 female participants, mean age 67 (SD 7), completed KOOS, VAS pain, function and patient global, SF-36, Physical Activity Scale, painDETECT, and the ADL Taxonomy. Patients were randomly assigned to one of two subgroups, completing either the paper or touch screen version first. Mean, mean differences (95% CI), median, median differences and Intraclass Correlation Coefficients (ICCs) were calculated for all questionnaires.</p> <p>Results</p> <p>ICCs between data based on computerized and paper versions ranged from 0.86 to 0.99. Analysis revealed a statistically significant difference between versions of the ADL Taxonomy, but not for the remaining questionnaires. Age, computer experience or education-level had no significant impact on the results. The computerized questionnaires were reported to be easier to use.</p> <p>Conclusion</p> <p>The computerized questionnaires gave comparable results to answers given on paper. Patient characteristics did not influence results and implementation was feasible.</p
A SynoviocyteModel for Osteoarthritis and Rheumatoid Arthritis: Response to Ibuprofen, Betamethasone, and Ginger Extract—A Cross-Sectional In Vitro Study
This study aimed at determining if synovial cell cultures from rheumatoid arthritis (RA), osteoarthritis (OA), and healthy controls (HC) differ and are suitable disease models in pharmacological studies, and tested their response to some anti-inflammatory drugs. Synovial cells were isolated from synovial membrane or joint fluid. Cells were cultivated and exposed to no or TNF-α stimulation without, or in the presence of, betamethasone, ibuprofen, or a standardized ginger extract. Concentrations of a panel of cytokines, growth factors, and chemokines were mapped for each culture and condition. Our cells secreted an increased amount of the cytokines IL-1β, IL-6, and IL-8 in response to TNF-α stimulation in all conditions. OA cells showed a higher IL-6 and IL-8 and a lower IL-1β production, when not stimulated, than RA and HC cells, which were similar. TNF-α stimulation caused similar IL-1β, IL-6, and IL-8 release in all groups. Ibuprofen showed no effect on cytokine production, while ginger extract was similar to betamethasone. Ginger extract was as effective an anti-inflammatory agent as betamethasone in this in vitro model. Cultured fibroblast-like synoviocytes from OA and RA subjects promise to be a useful pharmacological disease model, but further studies, to support results from such a model are needed
