    People with Parkinson's Disease experience gait impairments that significantly impact their quality of life. Visual, auditory, and tactile cues can alleviate gait impairments, but they can become less effective due to the progressive nature of the disease and changes in people's motor capability. In this study, we develop a human-in-the-loop (HIL) framework that monitors two key gait parameters, stride length and cadence, and continuously learns a person-specific model of how the parameters change in response to the feedback. The model is then used in an optimization algorithm to improve the gait parameters. This feasibility study examines whether auditory cues can be used to influence stride length in people without gait impairments. The results demonstrate the benefits of the HIL framework in maintaining people's stride length in the presence of a secondary task.Comment: 6 pages, 4 figures; the paper is accepted and presented at EMBC 202

    Papers presented: Correlation of Skeletal Muscles and Vitamin D by Hala M. Akhtar & Benjamin Ly There is More than Meets the Eye by Henry Nguyen, Anna Villarreal & Ryleigh Bryant The eyes are a very important organ so it is important that we take good care of them. The eye allows us to see and life as we know it could not be possible if we did not have eyesight. There is more than meets the eye as it can be threatened by disease that cannot be simply seen without the use of specially designed instruments or machines. Some of the diseases the eye can have are glaucoma, which causes a loss in eyesight overtime due to the increase in pressure within the eye. Retinopathy or also known as diabetic retinopathy which is caused by damage to the blood vessels of light sensitive tissue located in the back of the eye. Both of these diseases will take away one’s eyesight if not treated. Treatments for glaucoma can include medications and surgery such as laser eye surgery. It is very important to protect the eyes so that there is a reduced chance of complications of the eyes late in life

    BACKGROUND: Dementia is a progressive syndrome of global cognitive impairment with significant health and social care costs. Global prevalence is projected to increase, particularly in resource-limited settings. Recent policy changes in Western countries to increase detection mandates a careful examination of the diagnostic accuracy of neuropsychological tests for dementia. OBJECTIVES: To determine the diagnostic accuracy of the Montreal Cognitive Assessment (MoCA) at various thresholds for dementia and its subtypes. SEARCH METHODS: We searched MEDLINE, EMBASE, BIOSIS Previews, Science Citation Index, PsycINFO and LILACS databases to August 2012. In addition, we searched specialised sources containing diagnostic studies and reviews, including MEDION (Meta-analyses van Diagnostisch Onderzoek), DARE (Database of Abstracts of Reviews of Effects), HTA (Health Technology Assessment Database), ARIF (Aggressive Research Intelligence Facility) and C-EBLM (International Federation of Clinical Chemistry and Laboratory Medicine Committee for Evidence-based Laboratory Medicine) databases. We also searched ALOIS (Cochrane Dementia and Cognitive Improvement Group specialized register of diagnostic and intervention studies). We identified further relevant studies from the PubMed 'related articles' feature and by tracking key studies in Science Citation Index and Scopus. We also searched for relevant grey literature from the Web of Science Core Collection, including Science Citation Index and Conference Proceedings Citation Index (Thomson Reuters Web of Science), PhD theses and contacted researchers with potential relevant data. SELECTION CRITERIA: Cross-sectional designs where all participants were recruited from the same sample were sought; case-control studies were excluded due to high chance of bias. We searched for studies from memory clinics, hospital clinics, primary care and community populations. We excluded studies of early onset dementia, dementia from a secondary cause, or studies where participants were selected on the basis of a specific disease type such as Parkinson's disease or specific settings such as nursing homes. DATA COLLECTION AND ANALYSIS: We extracted dementia study prevalence and dichotomised test positive/test negative results with thresholds used to diagnose dementia. This allowed calculation of sensitivity and specificity if not already reported in the study. Study authors were contacted where there was insufficient information to complete the 2x2 tables. We performed quality assessment according to the QUADAS-2 criteria.Methodological variation in selected studies precluded quantitative meta-analysis, therefore results from individual studies were presented with a narrative synthesis. MAIN RESULTS: Seven studies were selected: three in memory clinics, two in hospital clinics, none in primary care and two in population-derived samples. There were 9422 participants in total, but most of studies recruited only small samples, with only one having more than 350 participants. The prevalence of dementia was 22% to 54% in the clinic-based studies, and 5% to 10% in population samples. In the four studies that used the recommended threshold score of 26 or over indicating normal cognition, the MoCA had high sensitivity of 0.94 or more but low specificity of 0.60 or less. AUTHORS' CONCLUSIONS: The overall quality and quantity of information is insufficient to make recommendations on the clinical utility of MoCA for detecting dementia in different settings. Further studies that do not recruit participants based on diagnoses already present (case-control design) but apply diagnostic tests and reference standards prospectively are required. Methodological clarity could be improved in subsequent DTA studies of MoCA by reporting findings using recommended guidelines (e.g. STARDdem). Thresholds lower than 26 are likely to be more useful for optimal diagnostic accuracy of MoCA in dementia, but this requires confirmation in further studies.This is the final version of the article.

    Promoting Physical Activity in Local Communities: Understanding Health, Nutrition, and Physical Activity Needs in Winooski, VT

    Get PDF
    Introduction: Since the Winooski YMCA opened in March 2008, enrollment has been much lower than expected, with only 200 members enrolled by September 2008. One goal of the YMCA is to promote the health of the community by increasing involvement in physical activity in Winooski. Regular exercise is associated with enhanced health and decreased risk of diabetes, cardiovascular disease, as well as many cancers. In order to promote physical activity in the Winooski community, the YMCA set a goal to increase their enrollment to 500 members by December 2008.https://scholarworks.uvm.edu/comphp_gallery/1005/thumbnail.jp

    Protected area designation and management in a world of climate change: A review of recommendations

    Get PDF
    Climate change is challenging conservation strategies for protected areas. To summarise current guidance, we systematically compiled recommendations from reviews of scientific literature (74 reviews fitting inclusion criteria) about how to adapt conservation strategies in the face of climate change. We focussed on strategies for designation and management of protected areas in terrestrial landscapes, in boreal and temperate regions. Most recommendations belonged to one of five dominating categories: (i) Ensure sufficient connectivity; (ii) Protect climate refugia; (iii) Protect a few large rather than many small areas; (iv) Protect areas predicted to become important for biodiversity in the future; and (v) Complement permanently protected areas with temporary protection. The uncertainties and risks caused by climate change imply that additional conservation efforts are necessary to reach conservation goals. To protect biodiversity in the future, traditional biodiversity conservation strategies should be combined with strategies purposely developed in response to a warming climate

    Evaluation of the analgesic effect of 4-anilidopiperidine scaffold containing ureas and carbamates

    Fentanyl is a powerful opiate analgesic typically used for the treatment of severe and chronic pain, but its prescription is strongly limited by the well-documented side-effects. Different approaches have been applied to develop strong analgesic drugs with reduced pharmacologic side-effects. One of the most promising is the design of multitarget drugs. In this paper we report the synthesis, characterization and biological evaluation of twelve new 4-anilidopiperidine (fentanyl analogues). In vivo hot-Plate test, shows a moderate antinociceptive activity for compounds OMDM585 and OMDM586, despite the weak binding affinity on both Ό and Ύ-opioid receptors. A strong inverse agonist activity in the GTP-binding assay was revealed suggesting the involvement of alternative systems in the brain. Fatty acid amide hydrolase inhibition was evaluated, together with binding assays of cannabinoid receptors. We can conclude that compounds OMDM585 and 586 are capable to elicit antinociception due to their multitarget activity on different systems involved in pain modulation. © 2016 Informa UK Limited, trading as Taylor & Francis Group

    Satisfaction with teledermatology in an underserved urban shelter setting

    Get PDF
    Problem Statement: People experiencing homelessness (PEH) face disproportionate access to dermatologic care. Teledermatology is a platform that may improve access to medical care in underserved communities. The literature is lacking on this topic. Project Aim: The purpose of this quality improvement initiative is to evaluate patient and provider satisfaction with teledermatology in an urban shelter setting. Satisfaction surveys will be distributed over one year to provide measurable data that are determinate (designed to highlight multiple satisfaction metrics, numerically), concise (designed with functionality and efficiency in mind) and relevant (validated across multiple studies).https://jdc.jefferson.edu/medposters/1021/thumbnail.jp
