Authors: Semanik Pamela , Wilbur Joellen , Sinacore James , Chang Rowland W. 
Published: April 2004

AbstractObjectiveTo identify physical activity behaviors of older (≥60 years) women with rheumatoid arthritis, and to determine if physical activity behavior differed by demographic characteristics or disease duration.MethodsCognitively intact, ambulatory women with rheumatoid arthritis seen at an urban university arthritis center (n = 185) responded to a survey that included demographics, number of years since RA diagnosis, and physical activity assessed with the Yale Physical Activity Survey.ResultsParticipants had a mean age of 70 years and a mean disease duration of 17.6 years. Mean total of physical activity, including low‐, moderate‐, and high‐intensity activity, was 23 hours/week, with 47 different physical activities identified. Housework comprised 67% of total physical activity time, whereas leisure activities and planned exercise comprised only 15% and 10%, respectively. Sixty percent of the women reported participation in some type of vigorous activity, and 88% reported they had done leisure walking in the past month. Age was negatively associated with scores on the activity summary index (r = –0.195, P < 0.01), and there was a significant difference on the activity summary index by employment status, with women in the work force (n = 47) and those involved in housekeeping (n = 105) scoring significantly higher (P = 0.003) than the women (n = 33) who described themselves as retired (F = 7.81, 2 degrees of freedom, P = 0.001).ConclusionOlder women with rheumatoid arthritis may participate in a broader array of physical activities than previously assumed, and could benefit from increasing the proportion of moderate or vigorous activity incorporated into their daily routines.

Authors: Rao Jaya K. , Weinberger Morris , Anderson Lynda A. , Kroenke Kurt 
Published: April 2004

AbstractObjectiveApproximately 25% of patients report unmet expectations after their doctor visits. In a longitudinal study of rheumatology patients, we examined whether changes in health status could predict unmet expectations.MethodsArthritis patients (n = 177) responded to 2 surveys (baseline and 6‐month followup). Both surveys contained questions on health status (functional status, pain, helplessness, psychological status) and visit duration. The followup survey contained questions on postvisit unmet expectations. Factors associated with unmet expectations were determined.ResultsFifty‐eight patients (33%) reported unmet expectations, most often for information (47%) and new medications (31%). Unmet expectations were more common among patients with greater baseline helplessness (odds ratio [OR] 1.9, 95% confidence interval [95% CI] 1.0–3.6) and short doctor visits at followup (OR 5.6, 95% CI 2.4–13.1). Unmet expectations were less common among those experiencing a decline in pain (OR 0.3, 95% CI 0.1–0.9).ConclusionAttention to the patient's level of pain and helplessness and duration of the visit may limit reports of unmet expectations.

Published: April 2004

AbstractObjectiveTo develop a comprehensive set of explicit process measures to assess the quality of health care for osteoarthritis, rheumatoid arthritis, and analgesics use.MethodsPotential quality measures and a summary of existing data to support or refute the relationship between the processes of care proposed in the indicators and relevant clinical outcomes were developed through a comprehensive literature review. The proposed measures and literature summary were presented to a multidisciplinary panel of experts in arthritis and pain. Using a modification of the RAND/UCLA Appropriateness Method, the panel rated each proposed measure for its validity as a measure of health care quality.ResultsAmong 66 proposed indicators, the expert panel rated 51 as valid measures of health care including 14 for osteoarthritis, 27 for rheumatoid arthritis, and 10 for analgesics use.ConclusionsSufficient scientific evidence and expert consensus exist to support a comprehensive set of measures to assess the quality of heath care for osteoarthritis, rheumatoid arthritis, and analgesics use. These measures can be used to gain an understanding of the quality of care for patients with arthritis.

AbstractObjectiveTo analyze the long‐term efficacy of 2 interventions for female fibromyalgia (FM) patients: 1) cognitive‐behavioral therapy (CBT), and 2) a physical exercise (PE)–based strategy.MethodsWe conducted a prospective, long‐term, randomized, parallel clinical trial. The outcome variables are physical activity, aerobic capacity, and results of the Fibromyalgia Impact Questionnaire (FIQ), Short Form 36, Beck Anxiety and Depression Inventory, Chronic Pain Self‐Efficacy Scale, and Chronic Pain Coping Inventory. All were measured at baseline, posttreatment, 6 months, and 1 year. The duration of both treatments was 8 weeks.ResultsSome items of the FIQ and some strategies to cope with pain improved significantly in both groups after treatment. All variables measuring functional capacity improved significantly in the PE group, whereas only physical activity of the vertebral column improved in the CBT group. There were no differences in anxiety, depression, and self efficacy after treatment in either group. After 1 year of followup, most of the parameters had returned to baseline values in both groups. However, in the PE group, functional capacity remained significantly better.ConclusionsPE and CBT improve clinical manifestations in FM patients only for short periods of time. Improvement in self efficacy and physical fitness are not associated with improvement in clinical manifestations.

Published: April 2004

AbstractObjectiveTo categorize radiographic joint damage as progressive or nonprogressive in individuals with rheumatoid arthritis (RA) participating in clinical studies.MethodsUsing the total Sharp radiographic damage score, erosion score, and joint space narrowing (JSN) score for 751 serial films of the hand/wrist and forefoot obtained from 190 patients with early RA during 6–60 months of followup (mean 31 months), various threshold values for progression of joint damage were evaluated singly and in various combinations. For each patient, the progression rate was estimated from the linear regression line for all available radiographic time points. After preliminary screening, 23 candidate definitions were tested to select a definition that discriminated well between radiographic progression and radiographic nonprogression.ResultsThe definition selected describes radiographic nonprogression in individual patients as an increase of ≤0.1 in the standardized response mean of the trimmed population (the central 95% of patients) for ≥5 of 6 change measures (erosion scores and JSN scores for the fingers, wrists, and feet). Using this definition, 59% of the 190 patients with early RA were defined as having nonprogressive radiographic damage. Moreover, 95% of 95 patients with progression of the total Sharp score at or below the median and 24% of 95 patients with progression of the total Sharp score above the median were defined as having nonprogressive joint damage (χ2 = 98, P < 0.0001), as were 97% of patients in the lowest quintile of total Sharp score progression rates and none of the patients in the highest progression quintile. Patients defined as nonprogressors had significantly lower baseline levels of C‐reactive protein and lower erythrocyte sedimentation rates compared with patients defined as progressors, and those patients in the nonprogressive joint damage group more frequently had American College of Rheumatology 20% and 50% improvement criteria responses, “good” improvements (decrease of ≥1.2) in the Disease Activity Score, and ≥50% decreases in the swollen joint counts during the first 2 years of followup.ConclusionRA joint damage in an observational cohort can be classified as progressive or nonprogressive with the use of a composite definition. Validation and/or refinement of this definition is needed by utilizing the data from controlled clinical trials that compare placebo with active treatment.

Published: April 2004

AbstractNew photoelectric observations of the eccentric orbit binary CW Cephei have been carried out in B, V and R colours during the 2000 observing season at TÜBITAK (The Scientific and Technical Research Council of Turkey) National Observatory. The light curves of the system were analyzed with a nonsynchronous rotation approach using the method of Wilson‐Devinney in B, V and R bands, simultaneously. Especially, we used the R band to check for a third light in the solution as distinct from previous studies. But, the third light contribution in the light curves comes out to be almost negligible. In this study, the values of the longitude of periastron (ω) of the system's orbit found in the solutions of the light curves and radial velocity curves were collected and the variation of ω with time was investigated. A new value of the apsidal motion velocity has been obtained as $ \dot \omega $ =0.0582 ± 0.0011 (deg/cycle), corresponding to an apsidal period U = 46 ± 1 yr. (© 2004 WILEY‐VCH Verlag GmbH & Co.

A framework for fusion methods and rendering techniques of multimodal volume data
Authors: Ferre Maria , Puig Anna , Tost Dani 
Published: April 2004

AbstractMany different direct volume rendering methods have been developed to visualize 3D scalar fields on uniform rectilinear grids. However, little work has been done on rendering simultaneously various properties of the same 3D region measured with different registration devices or at different instants of time. The demand for this type of visualization is rapidly increasing in scientific applications such as medicine in which the visual integration of multiple modalities allows a better comprehension of the anatomy and a perception of its relationships with activity. This paper presents different strategies of direct multimodal volume rendering (DMVR). It is restricted to voxel models with a known 3D rigid alignment transformation. The paper evaluates at which steps of the rendering pipeline the data fusion must be realized in order to accomplish the desired visual integration and to provide fast re‐renders when some fusion parameters are modified. In addition, it analyses how existing monomodal visualization algorithms can be extended to multiple datasets and it compares their efficiency and their computational cost.

Space–time blending
Authors: Pasko Galina , Pasko Alexander , Kunii Tosiyasu 
Published: April 2004

AbstractShape transformation between objects of different topology and positions in space is an open modelling problem. We propose a new approach to solving this problem for two given 2D or 3D shapes. The key steps of the proposed algorithm are: increase dimension by converting two input kD shapes into half‐cylinders in (k+1)D space–time, applying bounded blending with added material to the half‐cylinders, and making cross‐sections for getting intermediate shapes under the transformation. The additional dimension is considered as a time coordinate for making animation. We use the bounded blending set operations in space–time defined using R‐functions and displacement functions with the localized area of influence applied to the functionally defined half‐cylinders. The proposed approach is general enough to handle input shapes with arbitrary topology defined as polygonal objects with holes and disjoint components, set‐theoretic objects, or analytically defined implicit surfaces. The obtained unusual amoeba‐like behaviour of the shape combines metamorphosis with the non‐linear motion. Copyright © 2004 John Wiley & Sons, Ltd.
Capturing human motion using body‐fixed sensors: outdoor measurement and clinical applications
Authors: Aminian Kamiar , Najafi Bijan 
Published: April 2004

AbstractMotion capture is mainly based on standard systems using optic, magnetic or sonic technologies. In this paper, the possibility to detect useful human motion based on new techniques using different types of body‐fixed sensors is shown. In particular, a combination of accelerometers and angular rate sensors (gyroscopes) showed a promising design for a hybrid kinematic sensor measuring the 2D kinematics of a body segment. These sensors together with a portable datalogger, and using simple biomechanical models, allow capture of outdoor and long‐term movements and overcome some limitations of the standard motion capture systems. Significant parameters of body motion, such as nature of motion (postural transitions, trunk rotation, sitting, standing, lying, walking, jumping) and its spatio‐temporal features (velocity, displacement, angular rotation, cadence and duration) have been evaluated and compared to the camera‐based system. Based on these parameters, the paper outlines the possibility to monitor physical activity and to perform gait analysis in the daily environment, and reviews several clinical investigations related to fall risk in the elderly, quality of life, orthopaedic outcome and sport performance. Taking advantage of all the potential of these body‐fixed sensors should be promising for motion capture and particularly in environments not suitable for standard technology such as in any field activity.

AbstractRecent advances in genomics provide genetic information from humans and other mammals (mouse, rat, dog and primates) traditionally used as models as well as new candidates (pigs and cattle). In addition, linked enabling technologies, such as transgenesis and animal cloning, provide innovative ways to design and perform experiments to dissect complex biological systems. Exploitation of genomic information overcomes the traditional need to choose naturally occurring models. Thus, investigators can utilize emerging genomic knowledge and tools to create relevant animal models. This approach is referred to as reverse genetics. In contrast to ‘forward genetics’, in which gene(s) responsible for a particular phenotype are identified by positional cloning (phenotype to genotype), the ‘reverse genetics’ approach determines the function of a gene and predicts the phenotype of a cell, tissue, or organism (genotype to phenotype). The convergence of classical and reverse genetics, along with genomics, provides a working definition of a ‘genetic model’ organism (3). The recent construction of phenotypic maps defining quantitative trait loci (QTL) in various domesticated species provides insights into how allelic variations contribute to phenotypic diversity. Targeted chromosomal regions are characterized by the construction of bacterial artificial chromosome (BAC) contigs to isolate and characterize genes contributing towards phenotypic variation. Recombineering provides a powerful methodology to harvest genetic information responsible for phenotype. Linking recombineering with gene‐targeted homologous recombination, coupled with nuclear transfer (NT) technology can provide ‘clones’ of genetically modified animals.

Efficient Synthesis of 4‐(3′‐Furanyl)butenolide Derivatives via PdII‐Catalyzed Oxidative Heterodimeric Cyclization Reaction of 2,3‐Allenoic Acids and 1,2‐Allenyl Ketones
Authors: Ma Shengming , Yu Zhanqian 
Published: April 2004

AbstractThe oxidative cyclization/dimerization reaction between two classes of allenes with different functionalities was reported to provide an efficient route to polysubstituted 4‐(3′‐furanyl)‐2(5H)‐furanones, which are not readily available from the known methods. The highly optically active butenolides could be easily formed from the optically active 2,3‐allenoic acids, which was obtained conveniently through chiral resolution with optically active amines, that is, cinchonidine or α‐methyl benzylamine. A mechanistic study showed that the reaction proceeded via a matched double oxypalladation–reductive elimination process. The PdII species may be regenerated via the subsequent cyclometallation of two equivalents of 1,2‐allenyl ketones with Pd0 and protonlysis of Pd enolates formed with the in situ generated HCl.
