RESUMEN
BACKGROUND: As technology is advancing, so are the possibilities for new data collection methods in research, potentially improving data quality and validity of the results. In Sweden, a system using frequent repeated data collection using text messages, SMS Track, has been used in clinical research for more than a decade. In this paper, compliance with repeated text message questions was examined across five different studies, i.e. if compliance was 1: associated with study-specific factors (age or gender of the subjects, the condition, its' severity or course, i.e. improvement, relapse or steady state) and/or. 2: associated with the methodology itself (the question being asked, the frequency and number of questions, duration of data collection, initial compliance or the management of the system). METHODS: Descriptive comparisons were done across five studies. Three studies were collecting weekly responses over at least 52 weeks ("Weekly studies") and were used to investigate the effect of age, sex and pain severity on compliance, the effect of early compliance for late compliance, and finally the early occurrence of two successive weeks with non-compliance. RESULT: Compliance was excellent across all five studies, and only influenced somewhat by age, sex and pain-level. The factor "study" remained significant in the final model thus the observed differences may be a result of the conditions studied but does not seem to be attributable to severity or development of these conditions. Number and frequency of questions did not influence compliance, nor did study duration. CONCLUSIONS: Compliance was excellent in the included studies and was not affected by population factors. However, differences in compliance were observed that cannot be easily explained and warrant further investigation. In particular, the nature of the variables or the management of the study are potential areas for further investigations.

The Giant Mine is an abandoned gold mine in Yellowknife, Northwest Territories, Canada. Throughout its operation from 1948 to 2004, the Giant Mine released heavy amounts of arsenic trioxide into the environment, thus contaminating the soil and surface water within and around the vicinity of the mine site. Chronic arsenic (As) poisoning negatively impacts wildlife health and can induce multi-organ damages including neurodegeneration and visual dysfunction depending on concentration and duration of exposure. The aim of the current study was to comparatively assess retina layer changes and prevalence of ocular lesions in wild rodent populations (i.e. muskrats and red squirrels) breeding in arsenic endemic areas of Yellowknife, near the vicinity of the abandoned Giant mine site (â¼2 km radius), at an intermediate location (approximately 20 km from the mine area) as well as a reference location (spanning 52-105 km from the city of Yellowknife, Canada). Eye globes were removed from euthanized muskrats and squirrels from the three sampling locations with increasing distance from the Giant mine area. Optical Coherence Tomography (OCT) was used to attempt a pan-retinal layer assessment, and histologic examination was utilized for assessment and confirmation of ocular lesions. The retinal layers were measured and statistically compared between the groups based on sampling locations to enhance the scope of histologic evaluations. The preliminary results revealed that thicknesses of ganglion cell layer (GCL), retina nerve fibre layer (NFL), and inner retina layer (IR) were statistically reduced in the muskrats from arsenic endemic area, particularly near the vicinity of the Giant mine compared to the control group. Generalized ocular pathology was histologically confirmed in all the muskrats from the arsenic endemic areas with the manifestation of moderate to severe lymphocytic plasmacytic uveitis (LPU), keratitis and subcapsular cataracts. Inner retinal degeneration was also observed in all the muskrats from the arsenic endemic areas, while muskrats from the control group were predominantly normal. Three muskrats from the control group were noted to have a mild LPU and keratitis. Significant histopathologic changes were not detected in the squirrel eyes from the three groups except for incidental mild cornea scars from all the locations. In general, these preliminary findings confirm the presence of ocular lesions and retina abnormalities in wild muskrats in the Yellowknife area and provide the first evidence of visual dysfunction and impairment in wildlife inhabiting arsenic endemic areas of Canada.

Previous gold mining activities and arsenopyrite ore roasting activities at the Giant mine site (1948 to 2004) resulted in the release of high amounts of arsenic and trace metals into the terrestrial and aquatic ecosystems of Yellowknife, Northwest Territories, Canada. While elevated levels of arsenic has been consistently reported in surface soils and vegetation near the vicinity of the Giant mine area and in surrounding locations, systematic studies evaluating the overall health status of terrestrial small mammals endemic to the area are lacking. The purpose of this present study was to evaluate and comparatively assess the biochemical responses and histopathological effects induced by chronic arsenic and cadmium exposure in wild snowshoe hares breeding near the city of Yellowknife, specifically around the vicinity of the abandoned Giant mine site and in reference locations. Analysis included measurement of total arsenic and cadmium concentration in nails, livers, kidneys, bones, stomach content of hares, in addition to histopathological evaluation of hepatic and ocular lesions. Biochemical responses were determined through measurement of lipid peroxidation levels and antioxidant enzymes activities (catalase, superoxide dismutase, glutathione peroxidase, and glutathione disulfide). The results revealed that arsenic concentration was 17.8 to 48.9 times higher in the stomach content, and in the range of 4 to 23 times elevated in the nails of hares from the mine area compared to the reference location. Arsenic and cadmium levels were also noted to be increased in the bones, renal and hepatic tissues of hares captured near the mine area compared to the reference site. Specifically, hares from the mine area showed nail cadmium levels that was 2.3 to 17.6 times higher than those from the reference site. Histopathological examination of the eyes revealed no specific ocular lesions, such as lens opacity (cataracts) or conjunctivitis; however, hares from both locations exhibited hepatic steatosis (fatty liver change). Lipid peroxidation levels were relatively increased and accompanied with reduced antioxidant enzyme activities in hares from the mine area compared to the hares from the reference site. The results of this preliminary study suggest that the snowshoe hares breeding near the vicinity of Yellowknife, including near the Giant mine area have been chronically exposed to elevated levels of arsenic and cadmium, which consequently led to the increased levels of oxidative stress and perturbation of antioxidant defense system in exposed animals. The results of this present study constitute the first observation of chronic arsenicosis in wild small mammal species in Canada.

Pectinate ligament dysplasia (PLD) is a common cause of canine glaucoma and the definitive clinical diagnosis is based on gonioscopy. Although the histologic lesions of PLD have been described, it has not been determined whether these changes are specific for PLD or if similar histologic changes can develop as a consequence of secondary glaucoma. The filtration angles of 61 enucleated canine globes with chronic glaucoma were evaluated with light microscopy by 3 examiners who were masked to the clinical history, signalment, and gonioscopic results. A histologic diagnosis of PLD versus non-PLD was determined by each examiner based on previously reported morphologic criteria and compared with the clinical gonioscopic diagnosis. Of the 61 enucleated glaucomatous eyes, 40 were clinically diagnosed with PLD. For all 3 examiners, a histologic diagnosis of PLD corresponded poorly with the clinical diagnosis of PLD (range of kappa score: 0.149-0.269; range of AUC: 0.592-0.621). There was no difference between examiners in their ability to correctly diagnose PLD histologically (P = .978). A fair degree of agreement was noted among examiners in obtaining their suspected histologic diagnosis of PLD (kappa score 0.256). No individual or sets of histologic ICA features were consistent with clinical PLD. The results indicate the histologic ICA changes proposed to be characteristic of PLD are also noted in canine globes affected with chronic secondary glaucoma. Therefore, using routine histologic evaluation, a histologic diagnosis of PLD is not possible in the face of chronic canine glaucoma.

The impact of graded levels of day length on turkey health and behavior was determined in hens and toms raised to 18 wk of age. Birds were allocated to one of 4 lighting treatments (trt) providing 14 (14L), 17 (17L), 20 (20L), and 23 (23L) h of day length. Two time-replicated trials were completed with each, providing 2 rooms per lighting trt and each room having 3 hen (n = 720) and 3 tom (n = 480) pens. Data collection included gait score (GS), the incidence of footpad dermatitis (FPD), breast buttons and blisters, ocular size and pressure (males only), and behavioral observations (males only). Data were analyzed using SAS 9.3 based on a completely randomized design nested within 4 lighting trt. Regression analysis established relationships between response criteria and day length. Differences were considered significant at P ≤ 0.05 and trends noted at P ≤ 0.10. Gait score, FPD, and the incidence of breast buttons and blisters were assessed on 5 birds per pen at 11 and 17 wk of age. Average GS increased linearly with day length at 11 and 17 wk for both hens and toms, but the effect was larger in toms. Day length did not affect FPD, but more lesions and severe scores were found for hens than toms. The presence of breast buttons and blisters increased linearly with day length (11 wk) with the effect on blisters predominately seen in toms. Eye weight and size increased with increasing day length at 12 and 18 wk. Ocular pressure was not affected by day length. Infrared cameras recorded tom behavior over a 24 h period, and behaviors were classified over 10-min intervals using a scan sampling technique at 11 and 17 wk. Alterations in behavioral repertoire were observed with a linear increase in inactive resting and a linear decrease in standing, walking, preening, and environmental and feather pecking behaviors with increased day length. To conclude, day length affected bird mobility and incidence of breast blisters in an age- and gender-specific manner, and time spent inactive increased with longer day length.

INTRODUCTION: Assessing work ability and sickness certification are considered problematic by many physicians and education and implementation of guidelines to improve knowledge and skills has been requested. Our aim was to study the association between such interventions and physicians' sick-listing practices. METHODS: A web-based questionnaire was sent to all physicians working in primary care, psychiatry, orthopedics/rheumatology in the southern region of Sweden before (in 2007 to 1,063 physicians) and after (in 2009 to 1,164 physicians) educational interventions in insurance medicine were offered. RESULTS: With a response rate of 58%, half of the physicians (51%) reported to work at a clinic with a sick-listing policy in 2009 compared with 31% in 2007. Primary care physicians (OR 12.4) and physicians who had participated in educational interventions in insurance medicine (OR 2.4) more often had a sick-listing policy at the clinic. Physicians with a longer medical experience (OR 0.7) and those with support at the clinic (OR 0.3) and the possibility to extend time if needed (OR 0.4) were less likely to report of problematic cases while primary care physicians were (OR 2.9). On the contrary, physicians who reported to rarely have the possibility to extend time when handling problematic cases were more likely to issue a higher number of sickness certificates. CONCLUSIONS: The sick-listing process is often viewed as problematic and more often by primary care physicians. Benchmarking and education in insurance medicine together with the possibility to allocate extra time if encountering problematic cases may facilitate sick-listing practice.

The aim of this study was to ascertain experiences and perceptions among physiotherapists (PTs) in Sweden regarding the concept of work ability as well as their perspectives of their professional role in work ability assessments. We conducted an in-depth interview study with four male and twelve female physiotherapists working in the field of occupational health care, orthopaedics, primary health care or rehabilitation. Qualitative content analysis was applied to the data. Work ability was perceived as the ability to perform work tasks as requested. Having the potential to adjust at work and to allocate resources, having an attachment to the workplace and time factors were vital. The physiotherapists were striving for a well-defined role within a multiprofessional team, where work ability assessments were performed in a real work environment. The PTs experienced contradictory roles in relation to the patient but believed they could contribute with valuable material for assessments; this professional help was not always requested. It was noted that there was a need for experience and further education to enable PTs to further engage in work ability assessments. It is important to improve collaboration and to further discuss the work ability concept from the viewpoints of different professionals.

PURPOSE: The purpose of this study was to test the General Motor Function Assessment Scale (GMF) for content and criterion validity in geriatric home-rehabilitation. Furthermore, the GMF was analysed with respect to sensitivity, distribution, and for floor and ceiling effects. METHOD: Content validity was explored by questionnaires circulated to ten experts in the field of geriatrics. Three assessment instruments were used to test 66 patients in home rehabilitation. In order to evaluate criterion validity GMF results were compared to results from the ADL-taxonomy test, and the Timed 'Up and Go' (TUG) test. GMF scores were analysed regarding, sensitivity, distribution and to check for floor or ceiling effects. Comparisons between pre-intervention assessments and post-intervention assessments were also made. Non-parametric statistics were used. RESULTS: GMF covered and measured areas of relevance according to content validity. No floor effects in any of the subscales of GMF were seen. Comparison of pre-intervention and post-intervention assessments showed significant ceiling effects for all three subscales. As for criterion validity all subscales of GMF in terms of dependence, pain and insecurity correlated significantly with the activity parameter mobility of the ADL-taxonomy and TUG. GMF was sensitive enough to demonstrate changes between pre-intervention and post-intervention status. CONCLUSIONS: GMF is a relevant instrument of assessment suitable for physiotherapists rehabilitating elderly in the home environment. For elderly with minor functional limitations the GMF shows ceiling effects.

PURPOSE: The purpose of this study was to describe the development of the Motivation for Change Questionnaire (MCQ) and to test its intra-patient reliability on musculoskeletal pain patients in interdisciplinary rehabilitation as a basis for use in rehabilitation planning. METHOD: The MCQ questionnaire was developed from a literature search in the Medline, Cinahl and Psychlit databases concerning motivating factors for change in the life and work situation. Questions covering these factors were developed (item generation). Factor analysis of the questions implied a reduction of the number of questions (item reduction). Inter-item correlation was assessed on the baseline administration of the questionnaire by calculating Cronbach's alpha. When testing the structure of the scales, it was shown that the MCQ questionnaire could be described in two scales, one scale relating to motivation for change in the life situation and the other focusing on motivation for change in the work situation and in total 49 questions. RESULTS: The test -- retest reliability was calculated using the intra-class correlation coefficient (ICC) and 95% confidence intervals were calculated. One question was excluded due to the threshold limit of > 0.5. Seven scales relating to the life situation were accepted by the analysis: social support, mastery in life, challenges in life, control in life, values, self-efficacy and self-confidence. Six scales relating to the work situation were also accepted: co-worker support, supervisory support, challenges in work, job control, interaction and job-satisfaction. CONCLUSIONS: The MCQ questionnaire with 48 questions is reliable for use on musculoskeletal pain patients in interdisciplinary rehabilitation. It can be used to identify each individual's motivating factors for change in life and work situation as a basis for motivational work within rehabilitation and/or to measure within-subject changes in motivation over time. The validity and the responsiveness of the MCQ, need to be studied.

PURPOSE: To determine whether after prolonged storage of sclera in glycerin, there is any bacteriologic contamination that will reactivate, whether reconstituted sclera retains its tensile strength, and whether sclera retains its microstructural integrity. METHODS: Sixty-six scleral shells stored in glycerin for 9 to 19 years, as well as 11 controls stored for 6 months to 4 years, were studied by cutting a small wedge of tissue from the anterior margin of each and directly inoculating into thioglycolate broth, cutting an equatorial ring and determining its break strength using a tensiometer, and cutting a small piece from the remaining posterior portion and examining by scanning electron microscopy. RESULTS: After such prolonged storage, bacteriologic contamination was not detected, tensile strength generally increased with increasing duration of storage, and ultrastructural integrity was maintained on scanning electron microscopy. CONCLUSIONS: This study suggests that storage of scleral shells can be safely prolonged; we hope this can facilitate an increased supply of donated sclera to patients and surgeons.

OBJECTIVE: Investigation of the pathogenesis of Great Pyrenees retinopathy. ANIMALS: One male and two female puppies of parents who were affected with Great Pyrenees retinopathy and one 4-year-old affected adult male Great Pyrenees dog. PROCEDURE: The puppies were examined daily from 7 weeks of age by indirect ophthalmoscopy and their fundi were photographed until the lesions were static. Fluorescein angiography was completed at 7 weeks of age, within 24 h of detection of ophthalmoscopic lesions, and then weekly. The eyes of a 4-year-old and two 20-week-old puppies were examined with light microscopy, and transmitting and scanning electron microscopy. RESULTS: Blocked choroidal fluorescence was detected at 7 weeks of age. The blocked fluorescence enlarged, when the characteristic serous retinal detachments developed at 11 weeks of age. The detachments enlarged in size and number until the puppies were approximately 20 weeks old. Fluorescein pooling confirmed the presence of transient retinal pigment epithelial detachments. Leakage of dye into serous retinal detachments was not detected in this study. Light microscopy and transmitting and scanning electron microscopy confirmed the presence of multifocal serous retinal detachments with focal retinal degeneration that extended to the inner nuclear layer in a 4-year-old dog. The retinal detachments were accompanied by hypertrophy, hyperplasia, increased pigmentation, and vacuolation of the retinal pigment epithelium. CONCLUSIONS AND CLINICAL RELEVANCE: Great Pyrenees retinopathy is manifested by multifocal serous retinal and retinal pigment epithelial detachments. These detachments are similar to those noted with central serous retinopathy of humans. The sudden development of multifocal retinal and retinal pigment epithelial detachments, and the serous nature of these detachments, supports a theory that they develop secondary to focal secretion and absorption defects in retinal pigment epithelial cells. Given the age of the puppies when the blocked choroidal fluorescence was noted and maturation of the dog retina at 8 weeks postpartum, this retinopathy is considered to be a retinal pigment epithelial dysplasia. This unique inherited retinopathy offers an opportunity to study retinal pigment epithelial secretion.

Zinc, a trace element that influences cell metabolism through a variety of mechanisms, appears to play an integral role in maintaining normal ocular function. This element is present in high concentrations in ocular tissue, particularly in retina and choroid. Zinc deficiency has been shown in a number of species to result in a variety of gross, ultrastructural and electrophysiologic ocular manifestations. The physiological functions for zinc have been studied predominantly in retina and retinal pigment epithelium where zinc is believed to interact with taurine and vitamin A. modify photoreceptor plasma membranes, regulate the light-rhodopsin reaction, modulate synaptic transmission and serve as an antioxidant. Suboptimal zinc status in North America may influence the development and progression of several chronic eye diseases. Zinc supplementation trials and epidemiological studies have produced conflicting results concerning the role of zinc in age-related macular degeneration. Additional well-controlled supplementation trials are indicated to clarify the role of zinc in this disease. Future investigations must also expand our understanding of the mechanisms by which zinc regulates ocular morphology and function.

Eight African hedgehogs (Atelerix albiventris) were presented with unilateral proptosis. Six animals presented specifically for an ocular problem, whereas two had concurrent neurologic disease. Enucleation and light microscopic examination of tissues was performed in five animals, and euthanasia followed by complete postmortem examination was performed in three animals. Histopathologic findings in all hedgehogs included orbital cellulitis, panophthalmitis, and corneal ulceration, with perforation in seven of eight eyes. The etiology of the orbital cellulitis was not determined, but it appeared to precede proptosis. Orbits in hedgehogs are shallow and the palpebral fissures are large, which may predispose them to proptosis, similar to brachycephalic dogs. This clinical presentation was seen in 15% (8/54) of African hedgehogs presented to the Western College of Veterinary Medicine over a 2-yr period from January 1995 to December 1996 and warrants further investigation.

PURPOSE: To evaluate the two year outcome of multidisciplinary rehabilitation for patients with prolonged musculoskeletal disorders (MSDs), in terms of health-related quality of life (HRQL) and working ability. In addition, predictors of outcome were examined. METHODS: The rehabilitation group and the matched control group comprised 122 and 114 patients respectively. Baseline data were compared with two year follow-up data within and between the groups. The variables that were measured were: HRQL (Nottingham Health Profile), motivation, body awareness, pain, pain-related medicine consumption, psychosomatic symptoms, working environment and working ability. RESULTS: Variables which improved significantly for the rehabilitation group compared with the control group were: HRQL (p = 0.049), emotional reactions (p = 0.043), pain related to movements (p = 0.028) and need for pain-related medicines (p = 0.009). Multivariate regression analysis including all patients revealed that motivation was a predictor of change in HRQL (p = 0.001) and working ability (p < 0.001). CONCLUSION: The rehabilitation programme appeared to improve HRQL to a greater extent than ordinary treatment available within primary care. The patient's level of motivation could be an important predictor of outcome.

OBJECTIVES: To compare the cost-effectiveness of a multidisciplinary rehabilitation program with traditional treatment within primary care in terms of the health-related quality of life (HRQOL) in patients with prolonged musculoskeletal disorders (MSD) on the one hand and the costs to society on the other. Predictors of total costs, such as motivation, socio-economic level, age, pain, and working environment, were investigated. METHODS: A prospective, matched, controlled 2-year follow-up study was designed. The main outcome measures were HRQOL using the Nottingham Health Profile (NHP) and patient-specific total costs due to society. The cost-effectiveness was expressed as a quotient of the total costs to society/NHP global score difference value. RESULTS: Patients with prolonged MSD generate substantial total costs to society, chiefly in the area of indirect costs. Multidisciplinary rehabilitation improved HRQOL more cost-effectively. Motivation was revealed as a predictor of total costs. The relationship in savings in terms of indirect costs between the highly-motivated and the less-motivated patients was calculated at 4:1. CONCLUSIONS: The large group of patients with prolonged MSD generate substantial total costs, and even small reductions in direct and indirect costs could be of importance to society. The multidisciplinary rehabilitation program applied here was more cost-effective as compared with conventional treatment within primary care when it came to improving the patients' perceived HRQOL. Motivation could be a predictor of total costs, which has to be addressed in the process of identifying the patient as a partner in the rehabilitation process.
