    Background and Purpose. Current approaches to upper limb rehabilitation are not sufficient to drive neural reorganization and maximize recovery after stroke. To address this evidence-practice gap, a knowledge translation intervention using the Behaviour Change Wheel was developed. The intervention involves collaboratively working with stroke therapy teams to change their practice and increase therapy intensity by therapists prescribing supplementary self-directed arm exercise. The purposes of this case series are: (1) to provide an illustrative example of how a research-informed process changed clinical practice and (2) to report on staff members’ and patients’ perceptions of the utility of the developed intervention. Case Descriptions. A participatory action research approach was used in 3 stroke rehabilitation units in the United Kingdom. The intervention aimed to change 4 therapist-level behaviors: (1) screening patients for suitability for supplementary self-directed arm exercise, (2) provision of exercises, (3) involving family and caregivers in assisting with exercises, and (4) monitoring and progressing exercises. Data on changes in practice were collected by therapy teams using a bespoke audit tool. Utility of the intervention was explored in qualitative interviews with patients and staff. Outcomes. Components of the intervention were successfully embedded in 2 of the 3 stroke units. At these sites, almost all admitted patients were screened for suitability for supplementary self-directed exercise. Exercises were provided to 77%, 70%, and 88% of suitable patients across the 3 sites. Involving family and care givers and monitoring and progressing exercises were not performed consistently. Conclusions. This case report is an example of how a rigorous research-informed knowledge translation process resulted in practice change. Research is needed to demonstrate that these changes can translate into increased intensity of upper limb exercise and affect patient outcome

    The loss of normal regulation of corticosteroid secretion is important in the development of cardiovascular disease. We previously showed that microRNAs regulate the terminal stages of corticosteroid biosynthesis. Here, we assess microRNA regulation across the whole corticosteroid pathway. Knockdown of microRNA using Dicer1 siRNA in H295R adrenocortical cells increased levels of CYP11A1, CYP21A1, and CYP17A1 mRNA and the secretion of cortisol, corticosterone, 11-deoxycorticosterone, 18-hydroxycorticosterone, and aldosterone. Bioinformatic analysis of genes involved in corticosteroid biosynthesis or metabolism identified many putative microRNA-binding sites, and some were selected for further study. Manipulation of individual microRNA levels demonstrated a direct effect of miR-125a-5p and miR-125b-5p on CYP11B2 and of miR-320a-3p levels on CYP11A1 and CYP17A1 mRNA. Finally, comparison of microRNA expression profiles from human aldosterone-producing adenoma and normal adrenal tissue showed levels of various microRNAs, including miR-125a-5p to be significantly different. This study demonstrates that corticosteroidogenesis is regulated at multiple points by several microRNAs and that certain of these microRNAs are differentially expressed in tumorous adrenal tissue, which may contribute to dysregulation of corticosteroid secretion. These findings provide new insights into the regulation of corticosteroid production and have implications for understanding the pathology of disease states where abnormal hormone secretion is a feature

    AIM: To assess the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection and association with drug induced liver injury (DILI) in patients undergoing anti-tuberculosis (TB) therapy. METHODS: Four hundred and twenty nine patients with newly diagnosed TB - either active disease or latent infection - who were due to commence anti-TB therapy between September 2008 and May 2011 were included. These patients were prospectively tested for serological markers of HBV, HCV and human immunodeficiency virus (HIV) infections - hepatitis B core antigen (HBcAg), hepatitis B surface antigen (HBsAg), hepatitis B e antigen, IgG and IgM antibody to HBcAg (anti-HBc), HCV IgG antibody and HIV antibody using a combination of enzyme-linked immunosorbent assay, Western blot assay and polymerase chain reaction techniques. Patients were reviewed at least monthly during the TB treatment initiation phase. Liver function tests were measured prior to commencement of anti-TB therapy and 2-4 wk later. Liver function tests were also performed at any time the patient had significant nausea, vomiting, rash, or felt non-specifically unwell. Fisher’s exact test was used to measure significance in comparisons of proportions between groups. A P value of less than 0.05 was considered statistically significant. RESULTS: Of the 429 patients, 270 (62.9%) had active TB disease and 159 (37.1%) had latent TB infection. 61 (14.2%) patients had isolated anti-HBc positivity, 11 (2.6%) were also HBsAg positive and 7 (1.6%) were HCV-antibody positive. 16/270 patients with active TB disease compared to 2/159 patients with latent TB infection had markers of chronic viral hepatitis (HBsAg or HCV antibody positive; P = 0.023). Similarly the proportion of HBsAg positive patients were significantly greater in the active vs latent TB infection group (10/43 vs 1/29, P = 0.04). The prevalence of chronic HBV or HCV was significantly higher than the estimated United Kingdom prevalence of 0.3% for each. We found no association between DILI and presence of serological markers of HBV or HCV. Three (5.3%) patients with serological markers of HBV or HCV infection had DILI compared to 25 (9.5%) patients without; P = 0.04. CONCLUSION: Viral hepatitis screening should be considered in TB patients. DILI risk was not increased in patients with HBV/HCV

    The value of allied health professional research engagement on healthcare performance: a systematic review

    Get PDF
    Background Existing evidence suggests that clinician and organisation engagement in research can improve healthcare performance. However, current evidence has considered the relationship across all healthcare professions collectively. With the increase in allied health professional (AHP) clinical academic and research activity, it is imperative for healthcare organisations, leaders and managers to understand research engagement within these specific clinical fields. This systematic review aims to examine the value of research engagement by allied health professionals and organisations on healthcare performance. Methods This systematic review had a two-stage search strategy. Firstly, the papers from a previous systematic review examining the effect of research engagement in healthcare were screened to identify relevant papers published pre-2012. Secondly, a multi-database search was used to update the previous review but with a specific focus on allied health to identify publications from 2012 to date. Studies which explored the value of allied health research engagement on healthcare performance were included. All stages of the review were conducted by two reviewers independently, plus documented discussions with the wider research team when discrepancies occurred. Each study was assessed using the appropriate critical appraisal tool developed by the Joanna Briggs Institute. Results Twenty-two studies were included, of which six were ranked as high importance. This sample comprised mixed research designs. Overall, the findings indicated positive improvements in processes of care. The review also identified the most common mechanisms which may link research engagement with improvements to processes of care. Conclusion This landmark review is the first benchmark of evidence that explicitly shows improved processes of care and outcomes from AHP research engagement. The lack of transparent reporting of AHP research engagement highlights the need for clear recommendations in the design of future prospective studies. These proposals specifically include greater transparency in relation to AHP involvement, mechanisms and types of research engagement. The inclusion of these aspects as an integral component of future intervention study designs may contribute essential evidence of the value and impact of AHP research engagement

    Common Polymorphisms at the <i>CYP17A1 </i>Locus Associate With Steroid Phenotype:Support for Blood Pressure Genome-Wide Association Study Signals at This Locus

    Genome-wide association studies implicate the CYP17A1 gene in human blood pressure regulation although the causative polymorphisms are as yet unknown. We sought to identify common polymorphisms likely to explain this association. We sequenced the CYP17A1 locus in 60 normotensive individuals and observed 24 previously identified single-nucleotide polymorphisms with minor allele frequency &gt;0.05. From these, we selected, for further studies, 7 polymorphisms located ≤2 kb upstream of the CYP17A1 transcription start site. In vitro reporter gene assays identified 3 of these (rs138009835, rs2150927, and rs2486758) as having significant functional effects. We then analyzed the association between the 7 polymorphisms and the urinary steroid metabolites in a hypertensive cohort (n=232). Significant associations included that of rs138009835 with aldosterone metabolite excretion; rs2150927 associated with the ratio of tetrahydrodeoxycorticosterone to tetrahydrodeoxycortisol, which we used as an index of 17α-hydroxylation. Linkage analysis showed rs138009835 to be the only 1 of the 7 polymorphisms in strong linkage disequilibrium with the blood pressure–associated polymorphisms identified in the previous studies. In conclusion, we have identified, characterized, and investigated common polymorphisms at the CYP17A1 locus that have functional effects on gene transcription in vitro and associate with corticosteroid phenotype in vivo. Of these, rs138009835—which we associate with changes in aldosterone level—is in strong linkage disequilibrium with polymorphisms linked by genome-wide association studies to blood pressure regulation. This finding clearly has implications for the development of high blood pressure in a large proportion of the population and justifies further investigation of rs138009835 and its effects

    A survey of the current practice of intramuscular Botulinum toxin injections for hemiplegic shoulder pain in the UK

    Get PDF
    PURPOSE: To describe the current UK practice for the use of intramuscular Botulinum Toxin type A injections to treat hemiplegic shoulder pain. METHOD: A UK-based cross-sectional study using an online survey. Participants (n = 68) were medical and non-medical practitioners recruited via the membership of the British Society for Rehabilitation Medicine and the British Neurotoxin Network. Data was analysed using descriptive statistics and content analysis. RESULTS: The majority of respondents would consider Botulinum Toxin type A for hemiplegic shoulder pain (86.8%), though most of these respondents inject for this goal infrequently (83.1%). Pectoralis major was most commonly selected to achieve this goal. Barriers to this intervention included difficulties determining the cause of pain (29.4%), difficulty isolating muscles (27.9%), and a lack of evidence (25%). The doses reported regularly deviated from guidelines and a substantial range in the volumes suggested was observed. Clinicians were mostly reliant on unstandardised measures to assess outcomes. CONCLUSIONS: Current UK practice of Botulinum Toxin type A injections for hemiplegic shoulder pain associated with spasticity is highly variable. There are large gaps between current practice and available evidence with regards to muscle selection and doses used. A number of areas for further investigation have been identified to progress current understanding of this intervention. Implications for rehabilitation There are wide variations in practice for this complex intervention and clinicians should consider that their individual decision-making could be based on their own beliefs rather than available evidence. Pectoralis major is most commonly injected to treat hemiplegic shoulder pain, but further evaluation is required to address whether it is the most effective. Clinicians most often use a limitation of shoulder abduction and external rotation, flexor patterning of the upper limb, and pain on passive movement to identify when hemiplegic shoulder pain is due to spasticity over other causes. Further research is needed to identify which patients are most likely to benefit from this intervention and at what stage post-stroke its use is most optimal

    Implementing biomarkers to predict motor recovery after stroke

    Get PDF
    BACKGROUND: There is growing interest in using biomarkers to predict motor recovery and outcomes after stroke. The PREP2 algorithm combines clinical assessment with biomarkers in an algorithm, to predict upper limb functional outcomes for individual patients. To date, PREP2 is the first algorithm to be tested in clinical practice, and other biomarker-based algorithms are likely to follow. PURPOSE: This review considers how algorithms to predict motor recovery and outcomes after stroke might be implemented in clinical practice. FINDINGS: There are two tasks: first the prediction information needs to be obtained, and then it needs to be used. The barriers and facilitators of implementation are likely to differ for these tasks. We identify specific elements of the Consolidated Framework for Implementation Research that are relevant to each of these two tasks, using the PREP2 algorithm as an example. These include the characteristics of the predictors and algorithm, the clinical setting and its staff, and the healthcare environment. CONCLUSIONS: Active, theoretically underpinned implementation strategies are needed to ensure that biomarkers are successfully used in clinical practice for predicting motor outcomes after stroke, and should be considered in parallel with biomarker developmen

    Moving stroke rehabilitation evidence into practice: a systematic review of randomized controlled trials

    Get PDF
    Objective To investigate the effectiveness of interventions aimed at moving research evidence into stroke rehabilitation practice through changing the practice of clinicians. Data sources EMBASE, CINAHL, Cochrane and MEDLINE databases were searched from 1980 to April 2019. International trial registries and reference lists of included studies completed our search. Review methods Randomized controlled trials that involved interventions aiming to change the practice of clinicians working in stroke rehabilitation were included. Bias was evaluated using Revman to generate a risk of bias table. Evidence quality was evaluated using GRADE criteria. Results Sixteen trials were included (250 sites, 14,689 patients), evaluating a range of interventions including facilitation, audit and feedback, education, and reminders. Eleven studies included multicomponent interventions (using a combination of interventions). Four used educational interventions alone and one used electronic reminders. Risk of bias was generally low. Overall, the GRADE criteria indicated that this body of literature was low quality. This review found higher efficacy of trials which targeted fewer outcomes. Subgroup analysis indicated moderate level GRADE evidence (103 sites, 10,877 patients) that trials which included both site facilitation and tailoring for local factors were effective in changing clinical practice. The effect size of these varied (OR 1.63-4.9). Education interventions alone were not effective. Conclusions A large range of interventions are used to facilitate clinical practice change. Education is commonly used, but in isolation is not effective. Multicomponent interventions including facilitation and tailoring to local settings can change clinical practice and are more effective when targeting fewer changes

    A Functional Role for Modality-Specific Perceptual Systems in Conceptual Representations

    Get PDF
    Theories of embodied cognition suggest that conceptual processing relies on the same neural resources that are utilized for perception and action. Evidence for these perceptual simulations comes from neuroimaging and behavioural research, such as demonstrations of somatotopic motor cortex activations following the presentation of action-related words, or facilitation of grasp responses following presentation of object names. However, the interpretation of such effects has been called into question by suggestions that neural activation in modality-specific sensorimotor regions may be epiphenomenal, and merely the result of spreading activations from “disembodied”, abstracted, symbolic representations. Here, we present two studies that focus on the perceptual modalities of touch and proprioception. We show that in a timed object-comparison task, concurrent tactile or proprioceptive stimulation to the hands facilitates conceptual processing relative to control stimulation. This facilitation occurs only for small, manipulable objects, where tactile and proprioceptive information form part of the multimodal perceptual experience of interacting with such objects, but facilitation is not observed for large, nonmanipulable objects where such perceptual information is uninformative. Importantly, these facilitation effects are independent of motor and action planning, and indicate that modality-specific perceptual information plays a functionally constitutive role in our mental representations of objects, which supports embodied assumptions that concepts are grounded in the same neural systems that govern perception and action
