Abstract
BACKGROUND Consensus-based guidelines exist for adult athletes returning to play after concussion, but there are no protocols developed specifically for children. The goal of this knowledge translation research was to develop evidence-based materials to inform physicians about pediatric concussion. METHODS A pediatric concussion protocol was developed based on the National Institute for Health and Care Excellence procedures. RESULTS This return to activity protocol was developed to guide management when children/youth sustain a concussion. The protocol incorporated 3 main themes: (a) a protocol must include return to all activity, including sport and school; (b) existing consensus-based adult protocols are not appropriate for children; and (c) a more conservative protocol is needed. After pilot testing, the developed protocol is being used across Ontario. CONCLUSION Implementation of these new pediatric recommendations is an important addition to prevention of subsequent concussions during vulnerable recovery periods, with potential to facilitate recovery by preventing prolonged symptomatology, and secondary sequelae.

Abstract
OBJECTIVES Despite early treatment of urethral infection, gonorrhoea is endemic in urban populations of men who have sex with men (MSM) in Australia. By contrast, gonorrhoea is not common in urban heterosexual populations. Sexual activities among MSM usually involve anal or oral sex, and as these behaviours are becoming increasingly common among heterosexuals, there is a need to investigate their roles in transmission of gonorrhoea. METHODS We developed individual-based models of transmission of gonorrhoea in MSM and heterosexuals that incorporate anatomical site-specific transmission of gonorrhoea. We estimated the probabilities of transmission for anal sex and oral sex by calibrating an MSM model against prevalence of gonorrhoea and sexual activity data. These probabilities were then applied to a heterosexual model in order to examine whether gonorrhoea can persist in a heterosexual population through the addition of anal sex and oral sex. RESULTS In the MSM model, gonorrhoea can persist despite prompt treatment of urethral infections. The probability of gonorrhoea persisting is reduced if use of condom for oral sex is increased to more than 15% of acts. Assuming that treatment of symptomatic infections is prompt, gonorrhoea is unlikely to persist in a heterosexual population even with the addition of anal and oral sex. CONCLUSIONS Our models suggest that oral sex has an important role in sustaining gonorrhoea in a population of MSM by providing a pool of untreated asymptomatic infection. The importance of anal sex or oral sex in sustaining gonorrhoea in a heterosexual population remains uncertain due to the lack of information linking different types of sex acts and transmissibility.

Abstract
BACKGROUND Accumulating evidence supports an effect of aspirin in reducing overall cancer incidence and mortality in the general population. We reviewed current data and assessed the benefits and harms of prophylactic use of aspirin in the general population. METHODS The effect of aspirin for site-specific cancer incidence and mortality, cardiovascular events was collated from the most recent systematic reviews. Studies identified through systematic Medline search provided data regarding harmful effects of aspirin and baseline rates of harms like gastrointestinal bleeding and peptic ulcer. RESULTS The effects of aspirin on cancer are not apparent until at least 3 years after the start of use, and some benefits are sustained for several years after cessation in long-term users. No differences between low and standard doses of aspirin are observed, but there were no direct comparisons. Higher doses do not appear to confer additional benefit but increase toxicities. Excess bleeding is the most important harm associated with aspirin use, and its risk and fatality rate increases with age. For average-risk individuals aged 50-65 years taking aspirin for 10 years, there would be a relative reduction of between 7% (women) and 9% (men) in the number of cancer, myocardial infarction or stroke events over a 15-year period and an overall 4% relative reduction in all deaths over a 20-year period. CONCLUSIONS Prophylactic aspirin use for a minimum of 5 years at doses between 75 and 325 mg/day appears to have favourable benefit-harm profile; longer use is likely to have greater benefits. Further research is needed to determine the optimum dose and duration of use, to identify individuals at increased risk of bleeding, and to test effectiveness of Helicobacter pylori screening-eradication before starting aspirin prophylaxis.

Abstract
BACKGROUND A validated and reliable instrument was developed to knowledge, attitudes and behaviours with respect to evidence-based practice (EBB-KABQ) in medical trainees but requires further adaptation and validation to be applied across different health professionals. METHODS A modified 33-item evidence-based practice scale (EBP-KABQ) was developed to evaluate EBP perceptions and behaviors in clinicians. An international sample of 673 clinicians interested in treatment of pain (mean age = 45 years, 48% occupational therapists/physical therapists, 25% had more than 5 years of clinical training) completed an online English version of the questionnaire and demographics. Scaling properties (internal consistency, floor/ceiling effects) and construct validity (association with EBP activities, comparator constructs) were examined. A confirmatory factor analysis was used to assess the 4-domain structure EBP knowledge, attitudes, behavior, outcomes/decisions). RESULTS The EBP-KABQ scale demonstrated high internal consistency (Cronbach's alpha = 0.85), no evident floor/ceiling effects, and support for a priori construct validation hypotheses. A 4-factor structure provided the best fit statistics (CFI =0.89, TLI =0.86, and RMSEA = 0.06). CONCLUSIONS The EBP-KABQ scale demonstrates promising psychometric properties in this sample. Areas for improvement are described.

Abstract
Comparative effectiveness research (CER) strives for evidence to inform clinical decisions for specific clients in typical health care settings. While the randomized controlled trial (RCT) is well-aligned with the objectives of CER, this design may not be feasible or applicable to all research questions, particularly those pertaining to clinical decision making and individually based change. It is important, therefore, to consider alternative approaches, especially when studying complex and subjective outcomes such as children's participation. We propose the use of interrupted time series (ITS) quasi-experimental design for its potential application in determining the effectiveness of participation-focused interventions. In this perspective, ITS design is described, ascertaining its advantages and limitations, and suggestions are provided to overcome challenges to implementation. Results of a case study using the ITS approach to evaluate changes in participation of an adolescent with physical disabilities are described. Finally, strategies to implement this design in practice are suggested.

Abstract
Secondary analysis using data from a clinical trial was performed to evaluate the stability of individual items of the Mobility and Self-Care functional skills scales of the Pediatric Evaluation of Disability Inventory (PEDI). Parents of 113 children aged 1-6 years old with cerebral palsy completed the PEDI twice by questionnaire 6 months apart. An item was classified "unstable" if the score changed from capable to unable. The number of children with more than five unstable items and the number of items with more than five children having unstable scoring patterns were calculated. Nineteen children (17%) and 13 items had unstable scoring patterns. The majority of PEDI items demonstrated stability of parent scoring. Examination of unstable items suggests that parents may need assistance in understanding the difference between "usual" and "best" performance, interpreting descriptors such as "thoroughly," and maintaining the same context reference for outdoor mobility items.

Abstract
Participation in leisure is a human right and is central to the health of children and youth. The World Health Organization's International Classification of Functioning, Disability and Health for Children and Youth supported a change in thinking about what outcomes are most relevant in the context of children's health and places participation as one of the constituent elements of health. Participation is also a fundamental rehabilitation and health promotion outcome for children with cerebral palsy as identified by youth, parents, and health professionals. Several studies have identified individual and environmental factors related to participation in leisure; new studies are now determining the best interventions to promote participation. This article summarizes recent findings and proposes important topics for neurologists to consider in exploring leisure pursuits with children with cerebral palsy and their families and in working with rehabilitation professionals to promote engagement in leisure opportunities as part of integrated care.

Abstract
Children and youth with cerebral palsy receive ongoing physical and occupational therapy services to improve their functional performance and participation in activities at home, school, and in the community. Over the past 2 decades, rehabilitation interventions have become more functional and goal oriented. In this article, we discuss factors that have influenced emerging intervention approaches. These factors include greater involvement of families in decision making, changing conceptual frameworks and theories underlying skill development and improved outcome measures. New research findings indicate that rehabilitation interventions embracing family-centered services and focusing on functional improvement can be more effective in promoting participation. This knowledge can serve as the platform for further examination of the most effective rehabilitation interventions for children and youth with cerebral palsy.

Abstract
This article provides an overview of phase-contrast and time-spatial labeling inversion pulse MR imaging techniques to assess CSF movement in the CNS under normal and pathophysiologic situations. Phase-contrast can quantitatively measure stroke volume in selected regions, notably the aqueduct of Sylvius, synchronized to the heartbeat. Judicious fine-tuning of the technique is needed to achieve maximal temporal resolution, and it has limited visualization of CSF motion in many CNS regions. Phase-contrast is frequently used to evaluate those patients with suspected normal pressure hydrocephalus and a Chiari I malformation. Correlation with successful treatment outcome has been problematic. Time-spatial labeling inversion pulse, with a high signal-to-noise ratio, assesses linear and turbulent motion of CSF anywhere in the CNS. Time-spatial labeling inversion pulse can qualitatively visualize whether CSF flows between 2 compartments and determine whether there is flow through the aqueduct of Sylvius or a new surgically created stoma. Cine images reveal CSF linear and turbulent flow patterns.

Abstract
Background The purpose of this scoping review was to describe how three tenants of patient-centered care provision: communication, partnership, and health promotion are addressed in patient-centered care models/frameworks across the literature. Methods A scoping review of literature published in English since 1990 was conducted using Medline, CINAHL, and EMBASE. A key term search strategy was employed using “patient-centered care”, “client-centered care”, “framework” and “model” to identify relevant studies. Results Application of the search strategy resulted in a hit total of 101 articles. Nineteen articles met inclusion criteria, of which 12 were review articles; 5 were qualitative research papers; one was a randomized control trial; and one was a prospective study. From these articles, 25 different patient-centered care frameworks/models were identified. Conclusions The fact that all identified approaches to patient-centered care incorporated strategies to achieve effective communication, partnership, and health promotion indicates that clinicians can select a patient-centered approach from the literature that best suits their patient’s needs, and be confident that it will satisfy the three core elements of patient-centered care provision. While empirical literature on specific patient-centric frameworks and models was limited, much empiric evidence was sourced for the most consistently defined component of patient-centered care, communication.

Abstract
BACKGROUND AND PURPOSE The differentiation of pilocytic astrocytomas and high-grade astrocytomas is sometimes difficult. There are limited comparisons in the literature of the advanced MR imaging findings of pilocytic astrocytomas versus high-grade astrocytomas. The purpose of this study was to assess the MR imaging, PWI, DWI, and MR spectroscopy characteristics of pilocytic astrocytomas compared with high-grade astrocytomas. MATERIALS AND METHODS Sixteen patients with pilocytic astrocytomas and 22 patients with high-grade astrocytomas (8-66 years of age; mean, 36 ± 17 years) were evaluated by using a 1.5T MR imaging unit. MR imaging, PWI, DWI, and MR spectroscopy were used to determine the differences between pilocytic astrocytomas and high-grade astrocytomas. The sensitivity, specificity, and the area under the receiver operating characteristic curve of all analyzed parameters at respective cutoff values were determined. RESULTS The relative cerebral blood volume values were significantly lower in pilocytic astrocytomas compared with the high-grade astrocytomas (1.4 ± 0.9 versus 3.3 ± 1.4; P = .0008). The ADC values were significantly higher in pilocytic astrocytomas compared with high-grade astrocytomas (1.5 × 10(-3) ± 0.4 versus 1.2 × 10(-3) ± 0.3; P = .01). The lipid-lactate in tumor/creatine in tumor ratios were significantly lower in pilocytic astrocytomas compared with high-grade astrocytomas (8.3 ± 11.2 versus 43.3 ± 59.2; P = .03). The threshold values ≥1.33 for relative cerebral blood volume provide sensitivity, specificity, positive predictive values, and negative predictive values of 100%, 67%, 87%, and 100%, respectively, for differentiating high-grade astrocytomas from pilocytic astrocytomas. The optimal threshold values were ≤1.60 for ADC, ≥7.06 for lipid-lactate in tumor/creatine in tumor, and ≥2.11 for lipid-lactate in tumor/lipid-lactate in normal contralateral tissue. CONCLUSIONS Lower relative cerebral blood volume and higher ADC values favor a diagnosis of pilocytic astrocytoma, while higher lipid-lactate in tumor/creatine in tumor ratios plus necrosis favor a diagnosis of high-grade astrocytomas.

Abstract
BACKGROUND Fatigue is common in Crohn's disease (CD) and ulcerative colitis (UC). Data on fatigue in newly diagnosed patients are unavailable. AIM To report prevalence of fatigue in newly diagnosed CD and UC patients and examine its association with health-related quality of life (HRQOL), depression and disability. METHODS The Ocean State Crohn's and Colitis Area Registry (OSCCAR) is a statewide cohort of newly diagnosed inflammatory bowel disease patients in Rhode Island. Fatigue was assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Patients were administered instruments measuring HRQOL, overall disability and work impairment, and depression. RESULTS Fatigue was prevalent in 26.4% of 220 subjects. Cohen's d effect sizes for fatigue were large: Short-Form 36 Health Survey mental health component (CD 1.5, UC 1.4) and physical health component (CD 1.4, UC 1.4), EuroQol-5D valuation of current health state (CD 1.2, UC 1.0), Inflammatory Bowel Disease Questionnaire (CD 1.9, UC 1.6) and Patient Health Questionnaire depression scale (CD 1.8, UC 1.7). Fatigued patients reported more work impairment (Score difference: CD 29.5%, UC 23.8%) and activity impairment (score difference: CD 32.3%, UC 25.7%) on the Work Productivity and Activity Impairment Questionnaire. Fatigue's association with all scores remained highly significant despite controlling for disease activity. CONCLUSIONS Fatigue is strongly associated with poor HRQOL, disability and depression similarly in CD and UC even when controlling for disease activity. Fatigue's association with a wide range of patient-reported outcome measures suggests that monitoring fatigue is a simple way to screen for overall disruption in patient life.

Abstract
This study is a scoping review of 21 years of international occupational therapy literature. Its purpose is to identify and describe interventions used by occupational therapists to enable self-care, productivity, and leisure. The scoping review produced 59 articles published between 1990 and 2010. Nine articles evaluated the effectiveness of occupational therapy interventions focused on leisure outcomes, 21 on productivity outcomes, and 29 on self-care outcomes. The programs were classified according to eight types of interventions: training, education, skill development, task adaptation, occupational development, environmental modification, support provision, and support enhancement. Most studies produced at least one significant positive result (82%), indicating that occupational therapy programs were at least partially successful in improving self-care, productivity, or leisure. There is good evidence for task adaptation, training, and skill development interventions, and for the role of occupational therapy in multi-disciplinary teams.

Abstract
AIM To describe the pattern of use of rehabilitation services in children and adolescents with cerebral palsy (CP), and to identify factors associated with use. METHODS In this study, parents of 91 school-age children and 167 adolescents with CP completed a questionnaire regarding educational and rehabilitation resources received within the last 6 months. Rehabilitation services included occupational therapy (OT), physical therapy (PT), speech language pathology (SLP), psychology and special education. Demographic characteristics were documented and developmental and functional status was assessed. Relationships between service utilization and sociodemographic factors, functioning and school setting were determined. RESULTS Over half of children (53.2%) and adolescents (57.5%) were in regular schools; however, 41% of these required special education resources. The remainder (42.5-46.8%) was in special schools. The majority of children (84.6%) were receiving at least one rehabilitation service although this decreased (68.1%) in adolescence. PT and OT were most common and services were provided predominantly in the school setting. Services were primarily weekly direct interventions at school age, with weekly interventions or consultations most common for adolescents. Younger age was associated with service receipt at school age only. Children with greater motor limitations, lower IQ and greater activity limitations were more likely to receive OT, PT, SLP or special education. Children in segregated schools were significantly more likely to receive rehabilitation services, when compared with children in regular schools. CONCLUSIONS The majority of children and youth received one or more services. Individuals with greater motor or cognitive challenges were more likely to receive a range of school-based services from rehabilitation specialists. When compared with children of school age, adolescents were less likely to receive services and when provided, services were more likely to be consultative. Services may need to be more optimally organized through childhood to enhance benefits to children with CP across activity limitation profiles.

BACKGROUND The Child's Challenging Behaviour Scale (CCBS) was designed to measure a mother's rating of her child's challenging behaviours. The CCBS was initially developed for mothers of school-aged children with developmental disability and has previously been shown to have good psychometric properties using classical test theory techniques. The aim of this study was to use Rasch analysis to fully evaluate all aspects of the scale, including response format, item fit, dimensionality and targeting. METHODS The sample consisted of 152 mothers of a school-aged child (aged 5-18 years) with a disability. Mothers were recruited via websites and mail-out newsletters through not-for-profit organizations that supported families with disabilities. Respondents completed a survey which included the 11 items of the CCBS. Rasch analysis was conducted on these responses using the RUMM2030 package. RESULTS Rasch analysis of the CCBS revealed serious threshold disordering for nine of the 11 items, suggesting problems with the 5-point response format used for the scale. The neutral midpoint of the response format was subsequently removed to create a 4-point scale. High levels of local dependency were detected among two pairs of items, resulting in the removal of two items (item 7 and item 1). The final nine-item version of the scale (CCBS Version 2) was unidimensional, well targeted, showed good fit to the Rasch model, and strong internal consistency. CONCLUSIONS To achieve fit to the Rasch model it was necessary to make two modifications to the CCBS scale. The resulting nine-item scale with a 4-point response format showed excellent psychometric properties, supporting its internal validity.

Abstract
Client-centred occupational therapy approaches aim to increase client motivation and confidence in working towards self-identified occupational performance goals. In this opinion piece we explore whether measurement of confidence in goal pursuit could complement existing tools, such as the Canadian Occupational Performance Measure (Law et al 1998), in documenting clinical outcomes. Cognitive theories of motivation and behaviour change support links between confidence in problem solving around self-identified goals, effort, and motivation to persist and engage in therapy. We propose that evaluating goal-related confidence is an important but neglected area of practice. Providing feedback about confidence in relation to goal pursuit may increase the likelihood of occupational performance goals being attained.

Abstract
The purpose of this study was to examine the relationship between goal achievement measured by the Canadian Occupational Performance Measure (COPM) and child, goal, and intervention factors. Participants were 41 preschool children with cerebral palsy (CP) who were in the context-focused therapy arm of a randomized controlled trial. Factors including child age, Gross Motor Function Classification System (GMFCS) level, type and complexity of goals, and intervention strategies were analyzed. Children made large, positive mean changes on the COPM over 6 months (Performance = 3.8, SD = 1.9; Satisfaction = 4.3, SD 4.3) with younger children showing greater change. The COPM scores had low to moderate correlations with change on the Pediatric Evaluation of Disability Inventory and the Gross Motor Function Measure (GMFM-66). Regression analysis indicated that age, but not GMFCS level influenced COPM change scores. Goal complexity and intervention strategies were not significantly related to COPM change scores. The results provide support for using the COPM as an individualized measure of change in young children with CP receiving intervention.

Abstract
BACKGROUND Outcomes of health and rehabilitation services for children and youth with disabilities increasingly include assessments of health-related quality of life (HRQoL). The purpose of this research was to 1) describe overall patterns of HRQoL, 2) examine changes in parent's perceptions of child's HRQoL across 18 months and 3) explore factors that predict these changes. METHODS Participants in this study included 427 parents of children (229 boys and 198 girls) with a physically-based disability between the ages of 6 to 14 years. The Child Health Questionnaire (CHQ) was administered three times, at nine month intervals. Comparisons to the CHQ normative data were analyzed at Time 1 using t-tests, and change over time was examined using linear mixed-effects models. Possible predictors were modeled: 1) child's factors measured by the Activities Scale for Kids, Strengths and Difficulties Questionnaire, and general health measured by SF-36, 2) family characteristics measured by the Impact on Family Scale and 3) environmental barriers measured by the Craig Hospital Inventory of Environmental Factors. RESULTS CHQ scores of the study's participants demonstrated significantly lower summary scores from the normative sample for both CHQ Physical and Psychosocial summary scores. On average, children did not change significantly over time for physical summary scores. There was an average increase in psychosocial health that was statistically significant, but small. However, there was evidence of heterogeneity among children. Environmental barriers, behavioral difficulties, family functioning/impact, general health and child physical functioning had negative and significant associations with physical QoL at baseline. Change in physical QoL scores over time was dependent on children's behavioral difficulties, family functioning and environmental barriers. Environmental barriers, behavioral difficulties, family functioning/impact and general health had significant associations with psychosocial scores at baseline, but none served as predictors of change over time. CONCLUSIONS Children with physical disabilities differ from the normative group on parent ratings of their physical and psychosocial health. While there was little average change in CHQ scores over 18 months, there is evidence of heterogeneity among children. Factors such as environmental barriers, family functioning/impact, child physical functioning and behavioral difficulties and general health significantly influence QoL scores as measured by the CHQ.
