A study protocol of a randomised controlled trial to investigate if a community based strength training programme improves work task performance in young adults with Down syndrome
<p>Abstract</p> <p>Background</p> <p>Muscle strength is important for young people with Down syndrome as they make the transition to adulthood, because their workplace activities typically emphasise physical rather than cognitive skills. Muscle strength is reduced up to 50% in people with Down syndrome compared to their peers without disability. Progressive resistance training improves muscle strength and endurance in people with Down syndrome. However, there is no evidence on whether it has an effect on work task performance or physical activity levels. The aim of this study is to investigate if a student-led community-based progressive resistance training programme can improve these outcomes in adolescents and young adults with Down syndrome.</p> <p>Methods</p> <p>A randomised controlled trial will compare progressive resistance training with a control group undertaking a social programme. Seventy adolescents and young adults with Down syndrome aged 14-22 years and mild to moderate intellectual disability will be randomly allocated to the intervention or control group using a concealed method. The intervention group will complete a 10-week, twice a week, student-led progressive resistance training programme at a local community gymnasium. The student mentors will be undergraduate physiotherapy students. The control group will complete an arts/social programme with a student mentor once a week for 90 minutes also for 10 weeks to control for the social aspect of the intervention. Work task performance (box stacking, pail carry), muscle strength (1 repetition maximum for chest and leg press) and physical activity (frequency, duration, intensity over 7-days) will be assessed at baseline (Week 0), following the intervention (Week 11), and at 3 months post intervention (Week 24) by an assessor blind to group allocation. Data will be analysed using ANCOVA with baseline measures as covariates.</p> <p>Discussion</p> <p>This paper outlines the study protocol for a randomised controlled trial on the effects of progressive resistance training on work task performance and physical activity for adolescents and young adults with Down syndrome. The intervention addresses the impairment of muscle weakness which may improve work task performance and help to increase physical activity levels.</p> <p>Clinical trial registration number</p> <p>Australian New Zealand Clinical Trials Registry ACTRN12609000938202</p
DOGS: Reaction-Driven de novo Design of Bioactive Compounds
We present a computational method for the reaction-based de novo design of drug-like molecules. The software DOGS (Design of Genuine Structures) features a ligand-based strategy for automated ‘in silico’ assembly of potentially novel bioactive compounds. The quality of the designed compounds is assessed by a graph kernel method measuring their similarity to known bioactive reference ligands in terms of structural and pharmacophoric features. We implemented a deterministic compound construction procedure that explicitly considers compound synthesizability, based on a compilation of 25'144 readily available synthetic building blocks and 58 established reaction principles. This enables the software to suggest a synthesis route for each designed compound. Two prospective case studies are presented together with details on the algorithm and its implementation. De novo designed ligand candidates for the human histamine H4 receptor and γ-secretase were synthesized as suggested by the software. The computational approach proved to be suitable for scaffold-hopping from known ligands to novel chemotypes, and for generating bioactive molecules with drug-like properties
Can, Want and Try: Parents' Viewpoints Regarding the Participation of Their Child with an Acquired Brain Injury
BACKGROUND: Acquired brain injury (ABI) is a leading cause of permanent disability, currently affecting 20,000 Australian children. Community participation is essential for childhood development and enjoyment, yet children with ABI can often experience barriers to participation. The factors which act as barriers and facilitators to community participation for children with an ABI are not well understood. AIM: To identify the viewpoints of parents of children with an ABI, regarding the barriers and facilitators most pertinent to community participation for their child. METHODS: Using Q-method, 41 parents of children with moderate/severe ABI sorted 37 statements regarding barriers and facilitators to community participation. Factor analysis identified three viewpoints. RESULTS: This study identified three distinct viewpoints, with the perceived ability to participate decreasing with a stepwise trend from parents who felt their child and family "can" participate in viewpoint one, to "want" in viewpoint two and "try" in viewpoint three. CONCLUSIONS: Findings indicated good participation outcomes for most children and families, however some families who were motivated to participate experienced significant barriers. The most significant facilitators included child motivation, supportive relationships from immediate family and friends, and supportive community attitudes. The lack of supportive relationships and attitudes was perceived as a fundamental barrier to community participation. SIGNIFICANCE: This research begins to address the paucity of information regarding those factors that impact upon the participation of children with an ABI in Australia. Findings have implications for therapists, service providers and community organisations
THE MAGNETIC PROPERTIES OF A FERROFLUID WITH DIPOLAR INTERACTIONS
Un modèle décrivant les propriétés d'un ferrofluide contenant des particules interagissant faiblement est présenté. Le modèle est fondé sur la méthode de Monté-Carlo et il est utilisé pour étudier l'effet des interactions sur les courbes d'aimantation. Cet effet est de renforcer l'aimantation à un degré qui dépend du champ magnétique.A model of the properties of a ferrofluid containing weakly interacting particles is presented. The model is based on the Monte-Carlo method, and is used to study the effects of interactions on the magnetisation curve. It is shown that the effect of interactions is to enhance the magnetisation curve to a degree dependent on the magnetic field
"Please listen to me": A cross-sectional study of experiences of seniors and their caregivers making housing decisions

196325.pdf (publisher's version ) (Open Access)BACKGROUND: Little is known about the decision-making experiences of seniors and informal caregivers facing decisions about seniors' housing decisions when objective decision making measures are used. OBJECTIVES: To report on seniors' and caregivers' experiences of housing decisions. DESIGN: A cross-sectional study with a quantitative approach supplemented by qualitative data. SETTING: Sixteen health jurisdictions providing home care services, Quebec province, Canada. PARTICIPANTS: Two separate samples of seniors aged >/= 65 years and informal caregivers of cognitively impaired seniors who had made a decision about housing. MEASUREMENTS: Information on preferred choice and actual choice about housing, role assumed in the decision, decisional conflict and decision regret was obtained through closed-ended questionnaires. Research assistants paraphrased participants' narratives about their decision-making experiences and made other observations in standardized logbooks. RESULTS: Thirty-one seniors (median age: 85.5 years) and 48 caregivers (median age: 65.1 years) were recruited. Both seniors and caregivers preferred that the senior stay at home (64.5% and 71.7% respectively). Staying home was the actual choice for only 32.2% of participating seniors and 36.2% of the seniors cared for by the participating caregivers. Overall, 93% seniors and 71% caregivers reported taking an active or collaborative role in the decision-making process. The median decisional conflict score was 23/100 for seniors and 30/100 for caregivers. The median decision regret score was the same for both (10/100). Qualitative analysis revealed that the housing decision was influenced by factors such as seniors' health and safety concerns and caregivers' burden of care. Some caregivers felt sad and guilty when the decision did not match the senior's preference. CONCLUSION: The actual housing decision made for seniors frequently did not match their preferred housing option. Advanced care planning regarding housing and better decision support are needed for these difficult decisions
