- Abstract
Background: National strategies from North America call for substantive improvements in entry-level pain management education to help reduce the burden of chronic pain. Past work has generated a valuable set of interprofessional pain management competencies to guide the education of future health professionals. However, there has been very limited work that has explored the development of such competencies for individual professions in different regions. Developing profession-specific competencies tailored to the local context is a necessary first step to integrate them within local regulatory systems. Our group is working toward this goal within the context of entry-level physiotherapy (PT) programs across Canada. Aims: This study aimed to create a consensus-based competency profile for pain management, specific to the Canadian PT contextMethods: A modified Delphi was used to achieve consensus across Canadian university-based and clinical pain educators. Results: Representatives from 14 entry-level PT programs (93% of Canadian programs) and six clinical educators were recruited. After two rounds, a total of 15 competencies reached the pre-determined endorsement threshold (75%). Most participants (85%) reported being "very satisfied" with the process. Conclusions: This process achieved consensus on a novel pain management competency profile specific to the Canadian PT context. The resulting profile delineates the necessary abilities required by physiotherapists to manage pain upon entry-to-practice. Participants were very satisfied with the process. This study also contributes to the emerging literature on integrated research in pain management by profiling research methodology that can be used to inform related work in other health professions and regions.

- Abstract
QUESTION: Frequent severe wildfires have the potential to alter the structure and composition of forests in temperate biomes. While temperate forests dominated by resprouting trees are thought to be largely invulnerable to more frequent wildfires, empirical data to support this assumption are lacking. Does frequent fire erode tree persistence by increasing mortality and reducing regeneration, and what are the broader impacts on forest structure and understorey composition? LOCATION: Sub‐alpine open Eucalyptus pauciflora forests, Australian Alps, Victoria, Australia. METHODS: We examined tree persistence and understorey composition of E. pauciflora open forests that were unburned, burned once, twice or three times by high‐severity wildfires between 2003 and 2013. At each of 20 sites (five per fire frequency class) we assessed extent of top‐kill and mortality of eucalypt clumps, spatial configuration of surviving and dead clumps, densities of new and lignotuberous eucalypt seedlings, and shrub and grass cover. RESULTS: At least 2 yr after the last wildfire, proportions of top‐killed E. pauciflora stems were significantly higher, and densities of live basal resprouts significantly lower, at sites burned two or three times compared to once burned or unburned sites. Clump death increased to 50% of individuals at sites burned by three short‐interval wildfires, which led to changes in live tree patchiness, as indicated by nearest‐neighbour indices. Increased tree mortality was not offset by seedling recruitment, which was significantly lower at the twice‐ and thrice‐burned sites relative to single‐burn sites – although seedling recruitment was also influenced by topography and coarse woody debris. In addition to changes in the tree layer, the prominence of understorey shrubs was substantially reduced, and the frequency of grasses markedly increased, after two, and particularly three wildfires. CONCLUSIONS: Our study provides strong empirical evidence of ecologically signif

- Abstract
Objective: To create evidence-based guidelines evaluating foot care interventions for the management of juvenile idiopathic arthritis (JIA). Data Sources: An electronic literature search of the following databases from database inception to May 2015 was conducted: MEDLINE (Ovid), EMBASE (Ovid), Cochrane CENTRAL, and clinicaltrials.gov. Study Selection: The Ottawa Panel selection criteria targeted studies that assessed foot care or foot orthotic interventions for the management of JIA in those aged 0 to ≤18 years. The Physiotherapy Evidence Database scale was used to evaluate study quality, of which only high-quality studies were included (score, ≥5). A total of 362 records were screened, resulting in 3 full-text articles and 1 additional citation containing supplementary information included for the analysis. Data Extraction: Two reviewers independently extracted study data (intervention, comparator, outcome, time period, study design) from the included studies by using standardized data extraction forms. Directed by Cochrane Collaboration methodology, the statistical analysis produced figures and graphs representing the strength of intervention outcomes and their corresponding grades (A, B, C+, C, C−, D+, D, D−). Clinical significance was achieved when an improvement of ≥30% between the intervention and control groups was present, whereas P>.05 indicated statistical significance. An expert panel Delphi consensus (≥80%) was required for the endorsement of recommendations. Data Synthesis: All included studies were of high quality and analyzed the effects of multidisciplinary foot care, customized foot orthotics, and shoe inserts for the management of JIA. Custom-made foot orthotics and prefabricated shoe inserts displayed the greatest improvement in pain intensity, activity limitation, foot pain, and disability reduction (grades A, C+).Conclusions: The use of customized foot orthotics and prefabricated shoe inserts seems to be a good choice for managing foot pain and

Pain associated with bleeding disorders has been demonstrated to have an impact on patients’ and families’ quality of life. Both acute and chronic pain are common experiences and require attention by professionals working in haemophilia treatment centres (HTCs). The benefits of psychological pain management strategies such as cognitive behaviour therapy and self-management skills training are well documented; however, it is not well understood how Canadian social workers involved in haemophilia care perceive and provide pain management support to patients.

Chronic pain is common in people with bleeding disorders and can complicate clinical management, impair quality of life, and contribute to disability. People living with bleeding disorders often seek advice on pain management from the bleeding disorder treatment team; however, lack of condition-specific assessment tools to guide clinical communication about pain are a barrier to care.

14. A Method of Numerical Analysis of Plastic Flow in Plane Strain and Its Application to the Compression of a Ductile Material Between Rough Plates
- Author

Hill, R., Lee, E. H., and Tupper, S. J.
- Abstract
Problems of plastic flow which arise in practice, with complicated boundary conditions, are seldom amenable to exact analysis, and it becomes necessary to devise some numerical method of solution. This paper describes a rapid numerical procedure for the determination of the stress and velocity distributions in plane plastic flow where the plastic strains are large. The method is applied to the problem of the squeezing of a plastic material between rough plates. This example has been chosen as it illustrates the treatment of most types of boundary condition likely to be encountered and supplies for contrast several incomplete solutions attempted by previous authors. The solution shows the fallacy of the apparent static determinancy of the plane plastic problem, indicating the need to consider the velocity field in obtaining the true distribution of stress. A further advantage of this example is the possibility of checking the numerical procedure, which is found to be extremely accurate.

15. Analysis of Plastic Deformation in a Steel Cylinder Striking a Rigid Target

Lee, E. H. and Tupper, S. J.
- Abstract
The G. I. Taylor dynamic compression test consists of firing a cylinder of the material to be tested at a target of hardened armor plate, and deducing the dynamic yield stress from the resulting deformation. In the interpretation of the results, interest is concentrated on the wave front of initial plastic straining. The present paper attempts the theoretical determination of the entire strain distribution in such a test cylinder of nickel-chrome steel, this material being chosen since the dynamic influence on the stress-strain relation is likely to be small, thus permitting the static relation to be used in the theory. Strain distributions deduced by two theoretical approaches compare satisfactorily with the distribution of strain obtained in such a dynamic compression test, thus justifying the assumption for this material at the speed considered. The treatment of this problem requires a theory of the propagation of plastic waves, which is developed in this paper, for the particular type of stress-strain curve pertaining to the high-strength alloy steel tested.

- Abstract
Background: To identify baseline predictors of persisting pain in children with Juvenile Idiopathic Arthritis (JIA), relative to patients with JIA who had similar baseline levels of pain but in whom the pain did not persist., Methods: We used data from the Research in Arthritis in Canadian Children emphasizing Outcomes (ReACCh-Out) inception cohort to compare cases of 'moderate persisting pain' with controls of 'moderate decreasing pain'. Moderate pain was defined as a Visual Analogue Scale (VAS) for pain measurement score of > 3.5 cm. Follow-up was minimum 3 years. Univariate and Multivariate logistic regression models ascertained baseline predictors of persisting pain., Results: A total of 31 cases and 118 controls were included. Mean pain scores at baseline were 6.4 (SD 1.6) for cases and 5.9 (1.5) for controls. A greater proportion of cases than controls were females (77.4% vs 65.0%) with rheumatoid factor positive polyarthritis (12.9% vs 4.2%) or undifferentiated JIA (22.6% vs 8.5%). Oligoarthritis was less frequent in cases than controls (9.7% vs 33%). At baseline, cases had more active joints (mean of 11.4 vs 7.7) and more sites of enthesitis (4.6 vs 0.7) than controls. In the final multivariate regression model, enthesitis count at baseline (OR 1.40, CI 95% 1.19-1.76), female sex (4.14, 1.33-16.83), and the overall Quality of My Life (QoML) baseline score (0.82, 0.69-0.98) predicted development of persisting pain., Conclusions: Among newly diagnosed children with JIA with moderate pain, female sex, lower overall quality of life, and higher enthesitis counts at baseline predicted development of persisting pain. If our findings are confirmed, patients with these characteristics may be candidates for interventions to prevent development of chronic pain., (© 2023. BioMed Central Ltd., part of Springer Nature.)

- Abstract
Context: Pain is a primary reason individuals attend an Emergency Department (ED), and its management is a concern., Objectives: Change in symptoms and physiologic variables at 3 time points pre-post a ten-minute St. John Ambulance therapy dog team visit compared to no visit in ED patients who experienced pain., Design, Setting and Participants: Using a controlled clinical trial design, pain, anxiety, depression and well-being were measured with the Edmonton Symptom Assessment System (revised version) (ESAS-r) 11-point rating scales before, immediately after, and 20 minutes post- therapy dog team visit with Royal University Hospital ED patients participating in the study (n = 97). Blood pressure and heart rate were recorded at the time points. Control data was gathered twice (30 minutes apart) for comparison (n = 101). There were no group differences in age, gender or ethnicity among the control and intervention groups (respectively mean age 59.5/57.2, ethnicity 77.2% Caucasian/87.6%, female 43.6% /39.2%, male 56.4%/60.8%,)., Intervention: 10 minute therapy dog team visit in addition to usual care., Main Outcome Measures: Change in reported pain from pre and post therapy dog team visit and comparison with a control group., Results: A two-way ANOVA was conducted to compare group effects. Significant pre- post-intervention differences were noted in pain for the intervention (mean changeint. = -0.9, SD = 2.05, p = .004, 95% confidence interval [CI] = [0.42, 1.32], ηp2 = 04) but not the control group. Anxiety (mean changeint. = -1.13, SD = 2.80, p = .005, 95% CI = [0.56, 1.64], ηp2 = .04), depression (mean changeint. = -0.72, SD = 1.71, p = .002, 95% CI = [0.39, 1.11], ηp2 = .047), and well-being ratings (mean changeint. = -0.87, SD = 1.84, p < .001, 95% CI = [0.49, 1.25], ηp2 = .07) similarly improved for the intervention group only. There were no pre-post intervention differences in blood pressure or heart rate for either group. Strong responders to the intervention (i.e. >50% reduction) were observed for pain (43%), anxiety (48%), depression (46%), and well-being (41%)., Conclusions: Clinically significant changes in pain as well as significant changes in anxiety, depression and well-being were observed in the therapy dog intervention compared to control. The findings of this novel study contribute important knowledge towards the potential value of ED therapy dogs to affect patients' experience of pain, and related measures of anxiety, depression and well-being., Trial Registration: This controlled clinical trial is registered with ClinicalTrials.gov, registration number NCT04727749., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
While social workers have the capacity and scope of practice to make a significant contribution to pain management, little is understood about how they enact these roles. The initial goal of this scoping review was to examine the role of social work in pain management specifically in bleeding disorder care. Due to lack of published data on this topic, the review goal was broadened to chronic disease. Two electronic databases were searched providing a total of 13 published articles meeting the inclusion and exclusion criteria. Instrumental services, clinical services, and assessments were identified as primary roles of social workers, while advocacy, policy development, education, and skill development require further exploration in the literature.

- Abstract
Per- and polyfluoroalkyl substances (PFAS) are used in a wide variety of consumer products, including ski waxes, and are widespread persistent and hazardous environmental contaminants. We examined the environmental impact of ski wax use at an outdoor recreation area with significant cross-country ski activity by measuring PFAS levels in melted snow, soil and water following a collegiate ski race. We found extremely high levels of long- and short-chain PFAS (C4-C14) contamination in snow at the race start line (∑[PFAS] 7600-10,700 ng/L), with the longer-chain analytes (C10-C14) predominating. The complement of 14 PFAS detected in snow matched what has been found in ski wax. This snow contamination was greatly reduced at a point 3.9 km into the race. Soil at the start line contained the four most predominant PFAS in snow at a mean individual concentration of 2.81 ng/g dry weight. Control soil contained only perfluorooctane sulfonic acid (PFOS), not found in other soil samples, at a concentration of 2.80 ng/g. Shallow groundwater from an on-site well contained only the shorter-chain PFAS (C4-C8), with a mean individual concentration of 4.95 ng/L. Our results suggest that ski wax use, from which fluorocarbons abrade at very high levels onto snow during a ski race, are the main source of PFAS contamination at our site. Regulation of ski wax use is warranted to reduce PFAS pollution., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 The Author(s).

- Abstract
Objective: To identify early predictors of disease activity at 18 months in JIA using clinical and biomarker profiling., Methods: Clinical and biomarker data were collected at JIA diagnosis in a prospective longitudinal inception cohort of 82 children with non-systemic JIA, and their ability to predict an active joint count of 0, a physician global assessment of disease activity of ≤1 cm, and inactive disease by Wallace 2004 criteria 18 months later was assessed. Correlation-based feature selection and ReliefF were used to shortlist predictors and random forest models were trained to predict outcomes., Results: From the original 112 features, 13 effectively predicted 18-month outcomes. They included age, number of active/effused joints, wrist, ankle and/or knee involvement, ESR, ANA positivity and plasma levels of five inflammatory biomarkers (IL-10, IL-17, IL-12p70, soluble low-density lipoprotein receptor-related protein 1 and vitamin D), at enrolment. The clinical plus biomarker panel predicted active joint count = 0, physician global assessment ≤ 1, and inactive disease after 18 months with 0.79, 0.80 and 0.83 accuracy and 0.84, 0.83, 0.88 area under the curve, respectively. Using clinical features alone resulted in 0.75, 0.72 and 0.80 accuracy, and area under the curve values of 0.81, 0.78 and 0.83, respectively., Conclusion: A panel of five plasma biomarkers combined with clinical features at the time of diagnosis more accurately predicted short-term disease activity in JIA than clinical characteristics alone. If validated in external cohorts, such a panel may guide more rationally conceived, biologically based, personalized treatment strategies in early JIA., (© The Author(s) 2020.

- Abstract
Objective: To identify discrete clusters comprising clinical features and inflammatory biomarkers in children with JIA and to determine cluster alignment with JIA categories., Methods: A Canadian prospective inception cohort comprising 150 children with JIA was evaluated at baseline (visit 1) and after six months (visit 2). Data included clinical manifestations and inflammation-related biomarkers. Probabilistic principal component analysis identified sets of composite variables, or principal components, from 191 original variables. To discern new clinical-biomarker clusters (clusters), Gaussian mixture models were fit to the data. Newly-defined clusters and JIA categories were compared. Agreement between the two was assessed using Kruskal-Wallis analyses and contingency plots., Results: Three principal components recovered 35% (three clusters) and 40% (five clusters) of the variance in patient profiles in visits 1 and 2, respectively. None of the clusters aligned precisely with any of the seven JIA categories but rather spanned multiple categories. Results demonstrated that the newly defined clinical-biomarker lustres are more homogeneous than JIA categories., Conclusion: Applying unsupervised data mining to clinical and inflammatory biomarker data discerns discrete clusters that intersect multiple JIA categories. Results suggest that certain groups of patients within different JIA categories are more aligned pathobiologically than their separate clinical categorizations suggest. Applying data mining analyses to complex datasets can generate insights into JIA pathogenesis and could contribute to biologically based refinements in JIA classification., (© The Author(s) 2019.

- Abstract
We studied children enrolled within 90 days of juvenile idiopathic arthritis diagnosis in the Research in Arthritis in Canadian Children Emphasizing Outcomes (ReACCh-Out) prospective inception cohort to identify longitudinal trajectories of pain severity and features that may predict pain trajectory at diagnosis. A total of 1062 participants were followed a median of 24.3 months (interquartile range = 16.0-37.1 months). Latent trajectory analysis of pain severity, measured in a 100-mm visual analogue scale, identified 5 distinct trajectories: (1) mild-decreasing pain (56.2% of the cohort); (2) moderate-decreasing pain (28.6%); (3) chronically moderate pain (7.4%); (4) minimal pain (4.0%); and (5) mild-increasing pain (3.7%). Mean disability and quality of life scores roughly paralleled the pain severity trajectories. At baseline, children with chronically moderate pain, compared to those with moderate-decreasing pain, were older (mean 10.0 vs 8.5 years, P = 0.01) and had higher active joint counts (mean 10.0 vs 7.2 joints, P = 0.06). Children with mild-increasing pain had lower joint counts than children with mild-decreasing pain (2.3 vs 5.2 joints, P < 0.001). Although most children with juvenile idiopathic arthritis in this cohort had mild or moderate initial levels of pain that decreased quickly, about 1 in 10 children had concerning pain trajectories (chronically moderate pain and mild-increasing pain). Systematic periodic assessment of pain severity in the months after diagnosis may help identify these concerning pain trajectories early and lay out appropriate pain management plans. Focused research into the factors leading to these concerning trajectories may help prevent them.

- Abstract
Background: Exercise training is commonly recommended for adults with fibromyalgia. We defined whole body vibration (WBV) exercise as use of a vertical or rotary oscillating platform as an exercise stimulus while the individual engages in sustained static positioning or dynamic movements. The individual stands on the platform, and oscillations result in vibrations transmitted to the subject through the legs. This review is one of a series of reviews that replaces the first review published in 2002., Objectives: To evaluate benefits and harms of WBV exercise training in adults with fibromyalgia., Search Methods: We searched the Cochrane Library, MEDLINE, Embase, CINAHL, PEDro, Thesis and Dissertation Abstracts, AMED, WHO ICTRP, and ClinicalTrials.gov up to December 2016, unrestricted by language, to identify potentially relevant trials., Selection Criteria: We included randomized controlled trials (RCTs) in adults with the diagnosis of fibromyalgia based on published criteria including a WBV intervention versus control or another intervention. Major outcomes were health-related quality of life (HRQL), pain intensity, stiffness, fatigue, physical function, withdrawals, and adverse events., Data Collection and Analysis: Two review authors independently selected trials for inclusion, extracted data, performed risk of bias assessments, and assessed the quality of evidence for major outcomes using the GRADE approach. We used a 15% threshold for calculation of clinically relevant differences., Main Results: We included four studies involving 150 middle-aged female participants from one country. Two studies had two treatment arms (71 participants) that compared WBV plus mixed exercise plus relaxation versus mixed exercise plus relaxation and placebo WBV versus control, and WBV plus mixed exercise versus mixed exercise and control; two studies had three treatment arms (79 participants) that compared WBV plus mixed exercise versus control and mixed relaxation placebo WBV. We judged the overall risk of bias as low for selection (random sequence generation), detection (objectively measured outcomes), attrition, and other biases; as unclear for selection bias (allocation concealment); and as high for performance, detection (self-report outcomes), and selective reporting biases.The WBV versus control comparison reported on three major outcomes assessed at 12 weeks post intervention based on the Fibromyalgia Impact Questionnaire (FIQ) (0 to 100 scale, lower score is better). Results for HRQL in the control group at end of treatment (59.13) showed a mean difference (MD) of -3.73 (95% confidence interval [CI] -10.81 to 3.35) for absolute HRQL, or improvement of 4% (11% better to 3% worse) and relative improvement of 6.7% (19.6% better to 6.1% worse). Results for withdrawals indicate that 14 per 100 and 10 per 100 in the intervention and control groups, respectively, withdrew from the intervention (RR 1.43, 95% CI 0.27 to 7.67; absolute change 4%, 95% CI 16% fewer to 24% more; relative change 43% more, 95% CI 73% fewer to 667% more). The only adverse event reported was acute pain in the legs, for which one participant dropped out of the program. We judged the quality of evidence for all outcomes as very low. This study did not measure pain intensity, fatigue, stiffness, or physical function. No outcomes in this comparison met the 15% threshold for clinical relevance.The WBV plus mixed exercise (aerobic, strength, flexibility, and relaxation) versus control study (N = 21) evaluated symptoms at six weeks post intervention using the FIQ. Results for HRQL at end of treatment (59.64) showed an MD of -16.02 (95% CI -31.57 to -0.47) for absolute HRQL, with improvement of 16% (0.5% to 32%) and relative change in HRQL of 24% (0.7% to 47%). Data showed a pain intensity MD of -28.22 (95% CI -43.26 to -13.18) for an absolute difference of 28% (13% to 43%) and a relative change of 39% improvement (18% to 60%); as well as a fatigue MD of -33 (95% CI -49 to -16) for an absolute difference of 33% (16% to 49%) and relative difference of 47% (95% CI 23% to 60%); and a stiffness MD of -26.27 (95% CI -42.96 to -9.58) for an absolute difference of 26% (10% to 43%) and a relative difference of 36.5% (23% to 60%). All-cause withdrawals occurred in 8 per 100 and 33 per 100 withdrawals in the intervention and control groups, respectively (two studies, N = 46; RR 0.25, 95% CI 0.06 to 1.12) for an absolute risk difference of 24% (3% to 51%). One participant exhibited a mild anxiety attack at the first session of WBV. No studies in this comparison reported on physical function. Several outcomes (based on the findings of one study) in this comparison met the 15% threshold for clinical relevance: HRQL, pain intensity, fatigue, and stiffness, which improved by 16%, 39%, 46%, and 36%, respectively. We found evidence of very low quality for all outcomes.The WBV plus mixed exercise versus other exercise provided very low quality evidence for all outcomes. Investigators evaluated outcomes on a 0 to 100 scale (lower score is better) for pain intensity (one study, N = 23; MD -16.36, 95% CI -29.49 to -3.23), HRQL (two studies, N = 49; MD -6.67, 95% CI -14.65 to 1.31), fatigue (one study, N = 23; MD -14.41, 95% CI -29.47 to 0.65), stiffness (one study, N = 23; MD -12.72, 95% CI -26.90 to 1.46), and all-cause withdrawal (three studies, N = 77; RR 0.72, 95% CI -0.17 to 3.11). Adverse events reported for the three studies included one anxiety attack at the first session of WBV and one dropout from the comparison group ("other exercise group") due to an injury that was not related to the program. No studies reported on physical function., Authors' Conclusions: Whether WBV or WBV in addition to mixed exercise is superior to control or another intervention for women with fibromyalgia remains uncertain. The quality of evidence is very low owing to imprecision (few study participants and wide confidence intervals) and issues related to risk of bias. These trials did not measure major outcomes such as pain intensity, stiffness, fatigue, and physical function. Overall, studies were few and were very small, which prevented meaningful estimates of harms and definitive conclusions about WBV safety.

- Abstract
Objective: To create guidelines focused on the use of structured physical activity (PA) in the management of juvenile idiopathic arthritis (JIA)., Data Sources: A systematic literature search was conducted using the electronic databases Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), EMBASE (Ovid), and Physiotherapy Evidence Database for all studies related to PA programs for JIA from January 1966 until December 2014, and was updated in May 2015., Study Selection: Study selection was completed independently by 2 reviewers. Studies were included if they involved individuals aged ≤21 years diagnosed with JIA who were taking part in therapeutic exercise or other PA interventions for which effects of various disease-related outcomes were compared with a control group (eg, no PA program or activity of lower intensity)., Data Extraction: Two reviewers independently extracted information on interventions, comparators, outcomes, time period, and study design. The statistical analysis was reported using the Cochrane Collaboration methods. The quality of the included studies was assessed according to the Physiotherapy Evidence Database Scale., Data Synthesis: Five randomized controlled trials (RCTs) fit the selection criteria; of these, 4 were high-quality RCTs. The following recommendations were developed: (1) Pilates for improving quality of life, pain, functional ability, and range of motion (ROM) (grade A); (2) home exercise program for improving quality of life and functional ability (grade A); (3) aquatic aerobic fitness for decreasing the number of active joints (grade A); and (4) and cardio-karate aerobic exercise for improving ROM and number of active joints (grade C+)., Conclusions: The Ottawa Panel recommends the following structured exercises and physical activities for the management of JIA: Pilates, cardio-karate, home and aquatic exercises. Pilates showed improvement in a higher number of outcomes., (Copyright © 2017. Published by Elsevier Inc.)

- Abstract
Objective: To create evidence-based guidelines evaluating foot care interventions for the management of juvenile idiopathic arthritis (JIA)., Data Sources: An electronic literature search of the following databases from database inception to May 2015 was conducted: MEDLINE (Ovid), EMBASE (Ovid), Cochrane CENTRAL, and clinicaltrials.gov., Study Selection: The Ottawa Panel selection criteria targeted studies that assessed foot care or foot orthotic interventions for the management of JIA in those aged 0 to ≤18 years. The Physiotherapy Evidence Database scale was used to evaluate study quality, of which only high-quality studies were included (score, ≥5). A total of 362 records were screened, resulting in 3 full-text articles and 1 additional citation containing supplementary information included for the analysis., Data Extraction: Two reviewers independently extracted study data (intervention, comparator, outcome, time period, study design) from the included studies by using standardized data extraction forms. Directed by Cochrane Collaboration methodology, the statistical analysis produced figures and graphs representing the strength of intervention outcomes and their corresponding grades (A, B, C+, C, C-, D+, D, D-). Clinical significance was achieved when an improvement of ≥30% between the intervention and control groups was present, whereas P>.05 indicated statistical significance. An expert panel Delphi consensus (≥80%) was required for the endorsement of recommendations., Data Synthesis: All included studies were of high quality and analyzed the effects of multidisciplinary foot care, customized foot orthotics, and shoe inserts for the management of JIA. Custom-made foot orthotics and prefabricated shoe inserts displayed the greatest improvement in pain intensity, activity limitation, foot pain, and disability reduction (grades A, C+)., Conclusions: The use of customized foot orthotics and prefabricated shoe inserts seems to be a good choice for managing foot pain and function in JIA., (Copyright © 2016 American Congress of Rehabilitation Medicine.

- Abstract
Sulfogalactosylglycerolipid (SGG) is a sulfoglycolipid found ubiquitously in the plasma membrane of mammalian male germ cells. Although its exact cellular function(s) is unknown, it is speculated that SGG may play a role in cation transport, which may be important in sperm-egg interaction. Given the significant role of Ca2+ in many fertilization-related events, the purpose of this study was to determine whether Ca2+ interaction with the negatively charged sulfate group of SGG results in changes to the SGG lipid chain molecular dynamics and to compare these lipid dynamics with those resulting from Na+, Mg2+, or Sr2+ interaction with SGG. Pressure-tuning Fourier transform infrared spectroscopy was used in this study. The results obtained showed that all three divalent cations interacted electrostatically with the sulfate moiety of hydrated SGG, although with varying degrees of strength. It was found that the hydrocarbon chains of hydrated SGG-Na+ multilamellar bilayers were interdigitated, thus increasing disorderedness of the terminal CH3 group of the hydrocarbon chains. The presence of each of the three divalent cations abolished this interdigitation state. Presumably, this is through the cross-linking interaction of each divalent cation with the sulfate groups of neighboring lipid molecules. Moreover, divalent cation interaction was found to increase the lipid chain dynamics of SGG, with Mg2+ inducing the greatest chain disorder followed by Ca2+ and then Sr2+. An increase in chain disorder would increase the bilayer fluidity. Such a phenomenon may prove relevant to the changes observed in the sperm plasma membrane during fertilization-related events.

- Abstract
Sulfogalactosylceramide (SGC) is a sulfoglycolipid commonly found in epithelial cells and most animal germ cells. Its cellular function in sperm is unknown, although it has been implicated in cation transport in epithelial cells. The purpose of this study was to determine the lipid dynamic effects of Ca2+ binding to SGC. High-pressure Fourier transform infrared spectroscopy was used in this study. Our spectral results showed that Ca2+ bound to the sulfate moiety of SGC. Moreover, Ca2+ binding weakened the hydrogen bonding of the polar head region of SGC and the hydrocarbon chains became more disordered as revealed by an increase in the correlation field splitting pressure of SGC. Consequently, Ca2+ binding to SGC would increase the fluidity of SGC multibilayers. However, the presence of an alpha-hydroxyl group on the SGC fatty acid was found to strengthen the hydrogen bonding of the polar head region and as a consequence reduced the Ca(2+)-enhanced hydrocarbon chain disorder. Experimental approaches, described in this paper, serve as a model for further studies of the effects of Ca2+ binding on the dynamics of membranes containing SGC or other sulfatides.
