Abstract
Maternal mortality rates in low-middle income countries remain high, with sub-Saharan Africa accounting for two-thirds of global maternal deaths. Inadequate staff training is one of the main contributors to anaesthesia-related deaths and the Association of Anaesthetists developed the Safe Anaesthesia from Education course in collaboration with the World Federation of Societies of Anaesthesiologists to address this training gap. We aimed to evaluate the impact of this course among Kenyan participants. Mixed methodologies and secondary analyses of anonymised data were used to study translation of learning into practice. In total, 103 participants from 66 facilities who attended courses between 2016 and 2017 were analysed. Ninety (87%) participants who were followed up completed knowledge tests. Baseline median (IQR [range]) knowledge test score was 41 (37-43 [21-46]). There was a significant improvement in median (IQR [range]) knowledge test score immediately post-course (43 (41-45 [33-48]); p < 0.001) which was sustained at 3-6 month follow-up (43 (41-45 [32-50]); p < 0.001 compared with baseline). Eighty-four of the 103 participants were observed in their workplace and capability, opportunity and motivation-behaviour framework was used to study the barriers and facilitators to practice change. Psychological capability and reflective motivation were the main factors enabling positive behaviour change such as team communication and pre-operative assessment, whereas physical and social opportunity accounted for the main barriers to behaviours such as performing the surgical safety checklist. Our study demonstrates that the Safe Anaesthesia from Education obstetric course is relevant in the low-resource setting and may lead to knowledge translation in clinical practice.

Abstract
The growing field of regenerative rehabilitation has great potential to improve clinical outcomes for individuals with disabilities. However, the science to elucidate the specific biological underpinnings of regenerative rehabilitation-based approaches is still in its infancy and critical questions regarding clinical translation and implementation still exist. In a recent roundtable discussion from International Consortium for Regenerative Rehabilitation stakeholders, key challenges to progress in the field were identified. The goal of this article is to summarize those discussions and to initiate a broader discussion among clinicians and scientists across the fields of regenerative medicine and rehabilitation science to ultimately progress regenerative rehabilitation from an emerging field to an established interdisciplinary one. Strategies and case studies from consortium institutions-including interdisciplinary research centers, formalized courses, degree programs, international symposia, and collaborative grants-are presented. We propose that these strategic directions have the potential to engage and train clinical practitioners and basic scientists, transform clinical practice, and, ultimately, optimize patient outcomes.

Herb CC, Blemker S, Saliba S, Hart J, Hertel J. Chronic ankle instability patients exhibit higher variability in lower extremity joint-coupling variability during drop vertical jumps. J Biomech 2020; 99:109479. [PMID: 31744598 DOI: 10.1016/j.jbiomech.2019.109479] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 09/27/2019] [Accepted: 10/30/2019] [Indexed: 12/26/2022]
Abstract
Chronic ankle instability (CAI) has been associated with biomechanical alterations during landing tasks. While joint coupling differences have been reported during gait in patients with CAI, there is no known research assessing joint coupling during a drop-vertical jumping (DVJ). Joint coupling variability measure may provide information on the sensorimotor health of these patients. The purpose of this study was to compare lower extremity joint coupling variability during a DVJ between patients with CAI and controls. Twenty-eight young, active individuals (CAI:n = 14, Control:n = 14) participated in the study. A 3D motion capture system was used to collect kinematics during 15 drop-vertical jump trials. A vector coding analysis was used to assess the variability in the following joint couples: knee sagittal-ankle frontal, knee sagittal-ankle sagittal, hip frontal-ankle frontal, and hip frontal-ankle sagittal. The CAI group had higher joint coupling variability in hip frontal-ankle sagittal, knee sagittal-ankle frontal and knee sagittal-ankle sagittal planes both prior to and following ground contact during the drop vertical jumps. These changes indicate potential adaptations to the constraint of CAI and the task of the DVJ. Higher variability may reflect an attempt by the subjects to explore alternate movement strategies or reflect poor sensorimotor control strategies. Clinicians should consider the challenges of DVJ during rehabilitation as they create a unique task constraint.

Abstract
BACKGROUND AND PURPOSE The recently introduced Pipeline Flex Embolization Device with Shield Technology (Pipeline Shield) is the third generation of Pipeline flow-diverter devices. It has a new stent-surface modification, which reduces thrombogenicity. We aimed to evaluate clinical and radiographic (safety and efficacy) outcomes of the Pipeline Shield. MATERIALS AND METHODS The 30-day and 1-year mortality and morbidity rates and the 6- and 18-month radiographic aneurysm occlusion outcomes for procedures performed between March 2016 and January 2018 were analyzed. 3D-TOF-MRA was used for follow-up. RESULTS Forty-four attempted Pipeline Shield procedures were performed for 41 patients with 44 target aneurysms (total of 52 aneurysms treated). A total of 88.5% of devices were inserted in the anterior circulation, and 11.5%, in the posterior circulation; 49/52 (94.2%) aneurysms were saccular; and 1/52 (1.9%) was fusiform. One (1.9%) aneurysm was an iatrogenic pseudoaneurysm, and 1 (1.9%) was a dissecting aneurysm. Seventy-one percent (35/49) of the saccular aneurysms were wide-neck (neck, >4 mm), 34.6% (18/52) were large (≥10 mm), and 3.8% (2/52) were giant (≥25 mm). The mean aneurysm sac maximal diameter was 9.0 mm, and the mean neck width was 5.0 mm. The cumulative mortality and morbidity rates were 2.3% and 6.8% at 1 year, respectively. The adequate occlusion rate was 78.8% at 6 months and 90.3% at 18 months. CONCLUSIONS In this pragmatic and non-industry-sponsored study, the occlusion rates and safety outcomes were similar to those seen in previously published studies with flow-diverter devices and earlier generation Pipeline Embolization Devices.

Gait Posture 2019; 74:169-175. [PMID: 31525655 DOI: 10.1016/j.gaitpost.2019.09.010] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2019] [Revised: 08/30/2019] [Accepted: 09/09/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND Individuals with CAI have demonstrated a more inverted foot position during walking when compared to a healthy control group. Copers are individuals who have had an ankle sprain but learn to cope and return to pre-injury levels of function and may be a better comparison group than healthy controls because they have had the same initial injury. RESEARCH QUESTION A controlled laboratory study was performed to simultaneously analyze differences in lower extremity walking gait kinematics, kinetics, and surface electromyography (EMG) between individuals with CAI and copers at a preferred walking speed (PWS), 120% preferred walking speed (120WS), and standardized walking speed (SWS) of 1.34 m/s. METHODS Thirty-six (18 coper, 18 CAI) physically active individuals participated. Three-dimensional kinematics and kinetics at the ankle, knee, and hip and EMG amplitude for fibularis longus, tibialis anterior, medial gastrocnemius, and gluteus medius muscles were analyzed. Ten consecutive strides from each speed were analyzed using statistical parametric mapping (SPM). A 2 × 3 group by speed ANOVA and post-hoc t-tests were used to compare differences between the coper and CAI groups. RESULTS The CAI group had more ankle inversion at IC (PWS: MD = 4.2°, d = 1.08; 120WS: MD = 5.0°, d = 1.28; SWS: MD = 6.6°, d = 1.37) and greater peak inversion throughout swing at all three walking speeds (PWS: MD = 4.2°, d = 0.89; 120WS: MD = 4.4°, d = 0.91; SWS: MD = 6.2°, d = 1.21). The CAI group had greater peak hip adduction during swing (PWS: MD = 4.5°, d = 0.96; 120WS: MD = 4.1°, d = 1.04; SWS: MD = 3.6°, d = 0.98). SIGNIFICANCE The CAI group demonstrated greater ankle inversion at IC and during the swing phase and greater peak hip adduction during the swing phase compared to the copers. As the speed increased, ankle inversion in the CAI group also increased which could be linked to greater risk of recurrent sprains. Therefore, modeling gait training programs after the coper mechanics may be advantageous.

Abstract
ObjectiveTo determine if biological sex influenced performance on a novel dual-task (DT) assessment which consisted of commonly used clinical measures of sport concussion (SC) in healthy college students.BackgroundDT assessments consist of motor and cognitive tasks administered simultaneously and show promise as clinical measures of SC.Design/MethodsOur cross-sectional study included 60 (53.3% female) healthy, recreationally active college students (age = 20.5 ± 1.34 years, height = 171.7 ± 9.33 cm, mass = 69.25 ± 12.23 kg). Participants completed the Standardized Assessment of Concussion (SAC) and timed tandem gait (TTG) test independently (single task [ST]) and concurrently (DT). The revised SAC (45 points) which included a 10-word list was utilized. The TTG composite score was a sum of the average time to completion for each SAC task (3 trials for immediate memory [10-word list], up to 5 trials for the digits-backwards task, and one trial for the months in reverse order and delayed recall tasks). Independent t-tests were used to assess for sex differences for SAC and TTG performance during ST and DT administration. 2 × 2 factorial analyses of variance (ANOVA) were used to assess for sex (male, female) by task (ST, DT) interaction effects with effect sizes calculated using Cohen’s d. All analyses were assessed at α = 0.05.ResultsNo sex differences were observed for ST performance of the SAC (males = 37.1 ± 3.45 points, females = 37.4 ± 3.74 points; t[58] = 0.28, p = 0.78) or TTG (males = 44.3 ± 7.09 seconds, females = 46.1 ± 8.88 seconds; t[58] = 0.88, p = 0.38). No sex differences were observed for DT performance of the SAC (males = 39.7 ± 4.50 points, females = 39.2 ± 3.12 points; t[58] = 0.46, p = 0.64) or TTG (males = 52.1 ± 8.56 seconds, females = 52.1 ± 10.28 seconds; t[58] = 0.02, p = 0.98). No sex by task interaction effects were observed for SAC (F = 0.74, p = 0.39, d = 0.23) or TTG (F = 1.1, p = 0.30, d = 0.28) performance for ST or DT assessment.ConclusionsOur results indicate that our novel DT assessment was robust to sex differences in healthy college students which supports the utilization of our DT assessment across sexes without adjustment for interpretation.

Abstract
Abstract
Objective
Research examining the course of Alzheimer’s disease (AD) in Hispanics is lacking. This study examined demographic, psychiatric, cognitive, and genetic predictors of longitudinal functional change in Hispanics and non-Hispanics with AD.
Method
Longitudinal change in instrumental activities of daily living (IADL) was examined over 10 years (M = 4.15 years) in 292 subjects (Hispanic = 67, non-Hispanic = 225). All were part of the Texas Alzheimer’s Research & Care Consortium and included those with AD (n = 217) and those with mild cognitive impairment at baseline who progressed to AD at follow-up (n = 75). Baseline comparisons were conducted between ethnic groups for demographics, Geriatric Depression Scale (GDS-30) score, Mini Mental State Examination (MMSE) score, presence of apolipoprotein ɛ4 alleles (APOE4), and annualized IADL change scores and then entered into a multiple linear regression model as predictors of annualized IADL change.
Results
The Hispanic group had significantly more females (χ2 = 5.71, p = .017), lower education [MH = 9.96(4.39), MNH = 15.26(2.70)], higher depression scores [GDS-30; MH = 9.45(5.89), MNH = 5.51(4.29)], lower MMSE scores [MH = 23.31(4.33), MNH = 24.65(3.21)], and slower annualized IADL change [MH = 1.19(1.42), MNH = 2.02(1.60)]. Regression results were significant (F = 3.66, p = .001, R2 = .08 ), with higher baseline MMSE (p = .007) and Hispanic origin (p = .010) predicting slower annualized IADL change. Demographics, APOE4 status, and depression did not significantly predict IADL change.
Conclusions
Higher cognitive functioning at baseline and Hispanic origin was associated with slower functional decline over an average 4-year period of time. Despite having lower MMSE scores at baseline, greater depression, and less education, the Hispanic group had a slower decline in IADLs compared to non-Hispanics. Further research is needed to better understand how/why Hispanic origin is associated with slower functional decline.

Abstract
Abstract
Objective
Life expectancy varies between 3-12 years following the diagnosis of Alzheimer’s disease (AD) and is an important clinical question for patients and families. Current literature is limited by relatively small sample sizes and a reliance on clinical diagnoses. This study sought to evaluate predictors of AD life expectancy in a large autopsy-confirmed sample.
Methods
Baseline data from individuals 50 years and older clinically and neuropathologically diagnosed with AD (N=764) were obtained from the National Alzheimer’s Coordinating Center. Life expectancy was calculated in months from AD diagnosis to death. Nineteen variables (demographic, medical/health, disease severity, and psychiatric) obtained at dementia diagnosis were examined. Variables that showed significant differences in life expectancy using t-tests and Pearson correlations (14 of 19) were then entered into a forward multiple regression.
Results
Seven predictors in the model explained 27% of the variance in life expectancy (F= 40.7, R-squared= 0.267). Lower MMSE scores (β= 0.339, p < .001), male sex (β= -0.144, p < .001), older age (β= -0.130, p < .001), non-Hispanic Caucasian race/ethnicity (β= 0.115, p < .001), greater impairment on the Functional Activities Questionnaire (β= -0.091, p=.042), abnormal neurological/physical exam (β= -0.083, p=.011), and higher Neuropsychiatric Inventory Questionnaire total scores (β= -0.079, p=.016) predicted shorter life expectancy.
Conclusions
Global cognitive impairment, sex, age, race/ethnicity, functional impairment, abnormal neurological exam findings, and psychiatric symptoms explain a significant proportion of life expectancy following an AD diagnosis. Future studies should explore the relationship between life expectancy, specific neurological abnormalities, and psychiatric symptoms. These 7 predictors could potentially be used to predict life expectancy in individuals diagnosed with AD.

Abstract
There is an urgent need to improve access to safe surgical and anaesthetic care for children living in many low- and middle-income countries. Providing quality training for healthcare workers is a key component of achieving this. The 3-day Safer Anaesthesia from Education (SAFE)® paediatric anaesthesia course was developed to address the specific skills and knowledge required in this field. We undertook a project to expand this course across five East and Central African countries (Ethiopia, Kenya, Malawi, Uganda and Zambia) and train local faculty. This study reports the outcomes from course evaluation data, exploring the impact on knowledge, skills and behaviour change in participants. Eleven courses were conducted in a 15-month period, with 381 participants attending. Fifty-nine new faculty members were trained. Knowledge scores (0-50 scale) increased significantly from mean (SD) 37.5 (4.7) pre-course to 43.2 (3.5) post-course (p < 0.0001). Skills scores (0-10 scale) increased significantly from 5.7 (2.0) pre-course to 8.0 (1.5) post-course (p < 0.0001). One hundred and twenty-six participants in Malawi, Uganda and Zambia were visited in their workplace 3-6 months later. Knowledge and skills were maintained at follow-up, with scores of 41.5 (5.0) and 8.3 (1.4), respectively (p < 0.0001 compared with pre-course scores). Content analysis from interviews with these participants highlighted positive behaviour changes in the areas of preparation, peri-operative care, resuscitation, management of the sick child, communication and teaching. This study indicates that the SAFE paediatric anaesthesia course is an effective way to deliver training, and could be used to help strengthen emergency and essential surgical care for children as a component of universal health coverage.

Abstract
PURPOSE To investigate the effects of graft source, time since surgery, age, and sex on unilateral and symmetry-based measures of knee extension strength among individuals with ACL reconstruction (ACLR). METHODS Three hundred and eight individuals aged 13-40 years old with primary, unilateral ACLR in the last 60 months were enrolled in this multi-site clinical measurement study. Participants completed bilateral knee extension maximal voluntary isometric contraction (MVIC) torque assessments which were normalized to body mass (Nm/kg) and limb symmetry indices (LSI) were calculated. The effects of graft source (patellar tendon autograft; hamstring tendon autograft), time since surgery (≤ 12 months; >12 mo.), age (≤ 18 years; >18 years), and sex were evaluated using separate ANCOVAs. RESULTS A significant interaction was present between time since surgery and graft source for LSI (P = 0.01) as participants with patellar tendon autografts ≤ 12 months post-ACLR experienced the greatest asymmetry (LSI = 69.2 ± 24.5%). Significant interactions were present between time since surgery and sex for involved limb (P = 0.01) and uninvolved limb MVIC torque (P = 0.05) with females ≤ 12 months post-ACLR being weakest (involved MVIC = 1.81 ± 0.70 N m/kg; uninvolved MVIC = 2.40 ± 0.68 N m/kg). Participants ≤ 18-year-old displayed weaker involved limb (P < 0.001) and contralateral limb (P < 0.001) MVIC torque as compared to participants > 18-year-old during the first year after ACLR. CONCLUSIONS Graft source, sex, age, and time since surgery effect quadriceps strength and symmetry after ACLR. Surgical and demographic factors should be considered when developing treatment approaches to optimize quadriceps function prior to re-integration into pre-injury levels of physical activity.

Abstract
Background Technological support may be crucial in optimizing healthcare professional practice and improving patient outcomes. A focus on electronic health records has left other technological supports relatively neglected. Additionally, there has been no comparison between different types of technology-based interventions, and the importance of delivery setting on the implementation of technology-based interventions to change professional practice. Consequently, there is a need to synthesise and examine intervention characteristics using a methodology suited to identifying important features of effective interventions, and the barriers and facilitators to implementation. Three aims were addressed: to identify interventions with a technological component that are successful at changing professional practice, to determine if and how such interventions are theory-based, and to examine barriers and facilitators to successful implementation. Methods A literature review informed by realist review methods was conducted involving a systematic search of studies reporting either: (1) behavior change interventions that included technology to support professional practice change; or (2) barriers and facilitators to implementation of technological interventions. Extracted data was quantitative and qualitative, and included setting, target professionals, and use of Behaviour Change Techniques (BCTs). The primary outcome was a change in professional practice. A thematic analysis was conducted on studies reporting barriers and facilitators of implementation. Results Sixty-nine studies met the inclusion criteria; 48 (27 randomized controlled trials) reported behavior change interventions and 21 reported practicalities of implementation. The most successful technological intervention was decision support providing healthcare professionals with knowledge and/or person-specific information to assist with patient management. Successful technologies were more likely to operationalise BCTs, particularly “instruction on how to perform the behavior”. Facilitators of implementation included aligning studies with organisational initiatives, ensuring senior peer endorsement, and integration into clinical workload. Barriers included organisational challenges, and design, content and technical issues of technology-based interventions. Conclusions Technological interventions must focus on providing decision support for clinical practice using recognized behavior change techniques. Interventions must consider organizational context, clinical workload, and have clearly defined benefits for improving practice and patient outcomes.

Abstract
BACKGROUND The role of diet in multiple sclerosis (MS) is largely uncharacterized, particularly as it pertains to pediatric-onset disease. OBJECTIVE To determine the association between dietary factors and MS in children. METHODS Pediatric MS patients and controls were recruited from 16 US centers (MS or clinically isolated syndrome onset before age 18, <4 years from symptom onset and at least 2 silent lesions on magnetic resonance imaging). The validated Block Kids Food Screener questionnaire was administered 2011-2016. Chi-squared test compared categorical variables, Kruskal-Wallis test compared continuous variables, and multivariable logistic regression analysis was performed. RESULTS In total, 312 cases and 456 controls were included (mean ages 15.1 and 14.4 years). In unadjusted analyses, there was no difference in intake of fats, proteins, carbohydrates, sugars, fruits, or vegetables. Dietary iron was lower in cases ( p = 0.04), and cases were more likely to consume below recommended guidelines of iron (77.2% of cases vs 62.9% of controls, p < 0.001). In multivariable analysis, iron consumption below recommended guidelines was associated with MS (odds ratio = 1.80, p < 0.01). CONCLUSION Pediatric MS cases may be less likely to consume sufficient iron compared to controls, and this warrants broader study to characterize a temporal relationship. No other significant difference in intake of most dietary factors was found.

Abstract
Background Research findings indicate that working as a prison officer can be highly stressful, but the aspects of work that predict their mental health status are largely unknown. Aims To examine, using elements of the demands-resources model, the extent to which work pressure and several potential resources (i.e. control, support from managers and co-workers, role clarity, effective working relationships and positive change management) predict mental health in a sample of UK prison officers. Methods The Health and Safety Executive Management Standards Indicator Tool was used to measure job demands and resources. Mental health was assessed by the General Health Questionnaire-28. The effects of demands and resources on mental health were examined via linear regression analysis with GHQ score as the outcome. Results The study sample comprised 1267 prison officers (86% male). Seventy-four per cent met 'caseness' criteria for mental health problems. Job demands, poor interpersonal relationships, role ambiguity and, to a lesser extent, low job control and poor management of change were key predictors of mental health status. Conclusions The findings of this study can help occupational health practitioners and psychologists develop structured interventions to improve well-being among prison officers.

Abstract
BACKGROUND This clinical practice guideline was developed to determine the level of evidence supporting the clinical utility of commercially available multigene profiling assays and to provide guidance about whether certain breast cancer patient populations in Ontario would benefit from alternative tests in addition to Oncotype dx (Genomic Health, Redwood City, CA, U.S.A.). METHODS A systematic electronic Ovid search of the medline and embase databases sought out systematic reviews and primary literature. A systematic review and practice guideline was written by a working group and was then reviewed and approved by Cancer Care Ontario's Molecular Oncology Advisory Committee. RESULTS Twenty-four studies assessing the clinical utility of Oncotype dx, Prosigna (NanoString Technologies, Seattle, WA, U.S.A.), EndoPredict (Myriad Genetics, Salt Lake City, U.S.A.), and MammaPrint (Agendia, Irvine, CA, U.S.A.) were included in the evidence base. CONCLUSIONS The clinical utility of multigene profiling assays is currently established for an appropriate subset of patients with estrogen receptor-positive, her2-negative, node-negative breast cancer for whom a decision to give chemotherapy is difficult to make. For patients with estrogen receptor-positive tumours who receive tamoxifen alone, Oncotype dx, Prosigna, and EndoPredict validly identify a low-risk population with favourable outcomes, indicating that a low-risk assay result is actionable and the decision to withhold chemotherapy is supported. Clinical evidence indicates that a high Oncotype dx recurrence score can predict for chemotherapy benefit, but a high Prosigna or EndoPredict score, although prognostic, is not, based on clinical trial evidence, directly actionable. Prosigna and EndoPredict are statistically more likely to identify a population at risk for recurrence beyond 5 years, but that information is currently not actionable because of a lack of interventional studies.

Abstract
Chronic ankle instability (CAI) is a condition resulting from a lateral ankle sprain. Shank-rearfoot joint-coupling variability differences have been found in CAI patients; however, joint-coupling variability (VCV) of the ankle and proximal joints has not been explored. Our purpose was to analyse VCV in adults with and without CAI during gait. Four joint-coupling pairs were analysed: knee sagittal-ankle sagittal, knee sagittal-ankle frontal, hip frontal-ankle sagittal and hip frontal-ankle frontal. Twenty-seven adults participated (CAI:n = 13, Control:n = 14). Lower extremity kinematics were collected during walking (4.83 km/h) and jogging (9.66 km/h). Vector-coding was used to assess the stride-to-stride variability of four coupling pairs. During walking, CAI patients exhibited higher VCV than healthy controls for knee sagittal-ankle frontal in latter parts of stance thru mid-swing. When jogging, CAI patients demonstrated lower VCV with specific differences occurring across various intervals of gait. The increased knee sagittal-ankle frontal VCV in CAI patients during walking may indicate an adaptation to deal with the previously identified decrease in variability in transverse plane shank and frontal plane rearfoot coupling during walking; while the decreased ankle-knee and ankle-hip VCV identified in CAI patients during jogging may represent a more rigid, less adaptable sensorimotor system ambulating at a faster speed.
