Tortured refugees' expectations of a multidisciplinary pain rehabilitation programme: An explorative qualitative study
Background: Refugees have often been exposed to torture in their countries of origin. Rehabilitation of tortured refugees living in Denmark is offered by the specialized Rehabilitation and Research Centre for Torture Victims in Copenhagen. After an interdisciplinary assessment eligible patients are recommended rehabilitation. Objective: To explore tortured refugees' expectations of the multidisciplinary pain rehabilitation programme offered at our centre. Design: Explorative qualitative interview study. Patients: Fifteen consecutive Arabic-speaking men, waiting for rehabilitation after having been assessed by a physician, a psychologist, a physiotherapist and a social worker, were interviewed. Methods: Individual qualitative interviews were performed by an Arabic-speaking psychologist, and analysed with content analyses. Results: One theme: different expectations of multidisciplinary pain rehabilitation and 4 categories emerged: general expectations of the rehabilitation programme; specific expectations of professional treatment; expectations of mutual participation and communication; and expected rehabilitation outcomes. Conclusion: The tortured refugees had different, mostly positive, expectations of the multidisciplinary pain rehabilitation programme. General expectations of the rehabilitation content, as well as specific expectations of the professionals' treatment, were expressed. Mutual and active participation and communication between patients and therapists were important expectations. In addition, positive outcomes, such as improved health, improved coping ability and decreased pain, were expected
Computer-aided surface estimation of pain drawings – intra- and inter-rater reliability
Pain drawings are often utilized in the documentation of pain conditions. The aim here was to investigate intra- and inter-rater reliability of area measurements performed on pain drawings consecutively, using the computer program Quantify One. Forty-eight patients with chronic nonmalignant pain had shaded in their experienced pain on the front and back views of a pain drawing. The templates were scanned and displayed on a 17-inch computer screen. Two independent examiners systematically encircled the shaded-in areas of the pain drawings with help of a computer mouse, twice each on two separate days, respectively. With this method it is possible to encircle each marked area and to obtain immediate details of its size. The total surface area (mm2) was calculated for each pain drawing measurement. Each examiner measured about 2400 areas, and as a whole, the number of areas measured varied only by 3%. The intra-rater reliability was high with intraclass correlation coefficients 0.992 in Examiner A and 0.998 in Examiner B. The intra-individual absolute differences were small within patients within one examiner as well as between the two examiners. The inter-rater reliability was also high. Still, significant differences in the absolute mean areas (13%) were seen between the two examiners in the second to fourth measurement sessions, indicating that one of the examiners measured systematically less. The measurement error was ≤10%, indicating that use of the program would be advantageous both in clinical practice and in research, but if repeated, preferably with the same examiner. Since pain drawings with this method are digitized, high quality data without loss of information is possible to store in electronic medical records for later analysis, both regarding precise location and size of pain area. We conclude that the computer program Quantify One is a reliable method to calculate the areas of pain drawings
Three Clusters of Different Properties Characterize Women with Chronic Trapezius Myalgia
An increased response to experimental muscle pain is related to psychological status in women with chronic non-traumatic neck-shoulder pain
<p>Abstract</p> <p>Background</p> <p>Neck-shoulder pain conditions, e.g., chronic trapezius myalgia, have been associated with sensory disturbances such as increased sensitivity to experimentally induced pain. This study investigated pain sensitivity in terms of bilateral pressure pain thresholds over the trapezius and tibialis anterior muscles and pain responses after a unilateral hypertonic saline infusion into the right legs tibialis anterior muscle and related those parameters to intensity and area size of the clinical pain and to psychological factors (sleeping problems, depression, anxiety, catastrophizing and fear-avoidance).</p> <p>Methods</p> <p>Nineteen women with chronic non-traumatic neck-shoulder pain but without simultaneous anatomically widespread clinical pain (NSP) and 30 age-matched pain-free female control subjects (CON) participated in the study.</p> <p>Results</p> <p>NSP had lower pressure pain thresholds over the trapezius and over the tibialis anterior muscles and experienced hypertonic saline-evoked pain in the tibialis anterior muscle to be significantly more intense and locally more widespread than CON. More intense symptoms of anxiety and depression together with a higher disability level were associated with increased pain responses to experimental pain induction and a larger area size of the clinical neck-shoulder pain at its worst.</p> <p>Conclusion</p> <p>These results indicate that central mechanisms e.g., central sensitization and altered descending control, are involved in chronic neck-shoulder pain since sensory hypersensitivity was found in areas distant to the site of clinical pain. Psychological status was found to interact with the perception, intensity, duration and distribution of induced pain (hypertonic saline) together with the spreading of clinical pain. The duration and intensity of pain correlated negatively with pressure pain thresholds.</p
Process skill rather than motor skill seems to be a predictor of costs for rehabilitation after a stroke in working age; a longitudinal study with a 1 year follow up post discharge
<p>Abstract</p> <p>Background</p> <p>In recent years a number of costs of stroke studies have been conducted based on incidence or prevalence and estimating costs at a given time. As there still is a need for a deeper understanding of factors influencing these costs the aim of this study was to calculate the direct and indirect costs in a younger (<65) sample of stroke patients and to explore factors affecting the costs.</p> <p>Methods</p> <p>Fifty-eight patients included in a study of home rehabilitation and followed for 1 year after discharge from the rehabilitation unit, were interviewed about their use of health care services, assistance, medications and assistive devices. Costs (defined as the cost for society) were calculated. A linear regression of cost and variables of functioning, ability, community integration and health-related quality of life was done.</p> <p>Results</p> <p>Inpatient care contributed substantially to the direct cost with a mean length of stay of 92 days. Rehabilitation during the first year constituted of an average of 28 days in day clinics, 38 physiotherapy sessions and 20 occupational therapy sessions. The total direct mean cost was 80 020 € and the indirect cost 35 129 €. The direct costs were influenced by the process skill (the ability to plan and perform a given task and to adapt when needed) and presence of aphasia. Indirect costs for informal care giving increased for patients with a lower health-related quality of life as well as a low score on home integration.</p> <p>Conclusion</p> <p>Costs are high in this group of young (< 65 years) stroke patients compared to other studies, partly due to the length of the stay and partly to loss of productivity.</p
Company for the ultra-high density, ultra-short period sub-Earth GJ 367 b: discovery of two additional low-mass planets at 11.5 and 34 days
GJ 367 is a bright (V 10.2) M1 V star that has been recently found
to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the
aim of improving the planetary mass and radius and unveiling the inner
architecture of the system, we performed an intensive radial velocity follow-up
campaign with the HARPS spectrograph -- collecting 371 high-precision
measurements over a baseline of nearly 3 years -- and combined our Doppler
measurements with new TESS observations from sectors 35 and 36. We found that
GJ 367 b has a mass of = 0.633 0.050 M and a
radius of = 0.699 0.024 R, corresponding to
precisions of 8% and 3.4%, respectively. This implies a planetary bulk density
of = 10.2 1.3 g cm, i.e., 85% higher than
Earth's density. We revealed the presence of two additional non transiting
low-mass companions with orbital periods of 11.5 and 34 days and minimum
masses of = 4.13 0.36 M and
= 6.03 0.49 M, respectively,
which lie close to the 3:1 mean motion commensurability. GJ 367 b joins the
small class of high-density planets, namely the class of super-Mercuries, being
the densest ultra-short period small planet known to date. Thanks to our
precise mass and radius estimates, we explored the potential internal
composition and structure of GJ 367 b, and found that it is expected to have an
iron core with a mass fraction of 0.91. How this iron core is
formed and how such a high density is reached is still not clear, and we
discuss the possible pathways of formation of such a small ultra-dense planet.Comment: 28 pages, 11 figures. Accepted for publication in ApJ

Identification of Novel α-Synuclein Isoforms in Human Brain Tissue by using an Online NanoLC-ESI-FTICR-MS Method
Parkinson’s disease (PD) and Dementia with Lewy bodies (DLB) are neurodegenerative diseases that are characterized by intra-neuronal inclusions of Lewy bodies in distinct brain regions. These inclusions consist mainly of aggregated α-synuclein (α-syn) protein. The present study used immunoprecipitation combined with nanoflow liquid chromatography (LC) coupled to high resolution electrospray ionization Fourier transform ion cyclotron resonance tandem mass spectrometry (ESI-FTICR-MS/MS) to determine known and novel isoforms of α-syn in brain tissue homogenates. N-terminally acetylated full-length α-syn (Ac-α-syn1–140) and two N-terminally acetylated C-terminally truncated forms of α-syn (Ac-α-syn1–139 and Ac-α-syn1–103) were found. The different forms of α-syn were further studied by Western blotting in brain tissue homogenates from the temporal cortex Brodmann area 36 (BA36) and the dorsolateral prefrontal cortex BA9 derived from controls, patients with DLB and PD with dementia (PDD). Quantification of α-syn in each brain tissue fraction was performed using a novel enzyme-linked immunosorbent assay (ELISA)
The Glycosyltransferase Repertoire of the Spikemoss Selaginella moellendorffii and a Comparative Study of Its Cell Wall
Spike mosses are among the most basal vascular plants, and one species, Selaginella moellendorffii, was recently selected for full genome sequencing by the Joint Genome Institute (JGI). Glycosyltransferases (GTs) are involved in many aspects of a plant life, including cell wall biosynthesis, protein glycosylation, primary and secondary metabolism. Here, we present a comparative study of the S. moellendorffii genome across 92 GT families and an additional family (DUF266) likely to include GTs. The study encompasses the moss Physcomitrella patens, a non-vascular land plant, while rice and Arabidopsis represent commelinid and non-commelinid seed plants. Analysis of the subset of GT-families particularly relevant to cell wall polysaccharide biosynthesis was complemented by a detailed analysis of S. moellendorffii cell walls. The S. moellendorffii cell wall contains many of the same components as seed plant cell walls, but appears to differ somewhat in its detailed architecture. The S. moellendorffii genome encodes fewer GTs (287 GTs including DUF266s) than the reference genomes. In a few families, notably GT51 and GT78, S. moellendorffii GTs have no higher plant orthologs, but in most families S. moellendorffii GTs have clear orthologies with Arabidopsis and rice. A gene naming convention of GTs is proposed which takes orthologies and GT-family membership into account. The evolutionary significance of apparently modern and ancient traits in S. moellendorffii is discussed, as is its use as a reference organism for functional annotation of GTs
