Flexible context aware interface for ambient assisted living

A Multi Agent System that provides a (cared for) person, the subject, with assistance and support through an Ambient Assisted Living Flexible Interface (AALFI) during the day while complementing the night time assistance offered by NOCTURNAL with feedback assistance, is presented. It has been tailored to the subject’s requirements profile and takes into account factors associated with the time of day; hence it attempts to overcome shortcomings of current Ambient Assisted Living Systems. The subject is provided with feedback that highlights important criteria such as quality of sleep during the night and possible breeches of safety during the day. This may help the subject carry out corrective measures and/or seek further assistance. AALFI provides tailored interaction that is either visual or auditory so that the subject is able to understand the interactions and this process is driven by a Multi-Agent System. User feedback gathered from a relevant user group through a workshop validated the ideas underpinning the research, the Multi-agent system and the adaptable interface

Night optimised care technology for users needing assisted lifestyles

There is growing interest in the development of ambient assisted living services to increase the quality of life of the increasing proportion of the older population. We report on the Night Optimised Care Technology for UseRs Needing Assisted Lifestyles project, which provides specialised night time support to people at early stages of dementia. This article explains the technical infrastructure, the intelligent software behind the decision-making driving the system, the software development process followed, the interfaces used to interact with the user, and the findings and lessons of our user-centred approach

Situational-Context for Virtually Modeling the Elderly

The generalized aging of the population is incrementing the pressure over, frequently overextended, healthcare systems. This situations is even worse in underdeveloped, sparsely populated regions like Extremadura in Spain or Alentejo in Portugal. In this paper we propose an initial approach to use the Situational-Context, a technique to seamlessly adapt Internet of Things systems to the needs and preferences of their users, for virtually modeling the elderly. These models could be used to enhance the elderly experience when using those kind of systems without raising the need for technical skills. The proposed virtual models will also be the basis for further eldercare innovations in sparsely populated regions

Participatory research to design a novel system to support the night-time needs of people with dementia; NOCTURNAL

Strategies to support people living with dementia are broad in scope, proposing both pharmacological and non-pharmacological interventions as part of the care pathway. Assistive technologies form part of this offering as both stand-alone devices to support particular tasks and the more complex offering of the “smart home” to underpin ambient assisted living. This paper presents a technology-based system, which expands on the smart home architecture, orientated to support people with daily living. The system, NOCTURNAL, was developed by working directly with people who had dementia, and their carers using qualitative research methods. The research focused primarily on the nighttime needs of people living with dementia in real home settings. Eight people with dementia had the final prototype system installed for a three month evaluation at home. Disturbed sleep patterns, night-time wandering were a focus of this research not only in terms of detection by commercially available technology but also exploring if automated music, light and visual personalized photographs would be soothing to participants during the hours of darkness. The NOCTURNAL platform and associated services was informed by strong user engagement of people with dementia and the service providers who care for them. NOCTURNAL emerged as a holistic service offering a personalised therapeutic aspect with interactive capabilities

Recent results in the decoding of Algebraic geometry codes

Objectives: The aim of this study was to examine the relationships between perceived teacher autonomy support versus control and students’ life skills development in PE, and whether students’ basic need satisfaction and frustration mediated these relationships. Design: Cross-sectional study. Method: English and Irish students (N = 407, Mage = 13.71, SD = 1.23) completed measures assessing perceived autonomy-supportive and controlling teaching, basic need satisfaction and frustration (autonomy, competence, and relatedness), and life skills development in PE (teamwork, goal setting, social skills, problem solving and decision making, emotional skills, leadership, time management, and interpersonal communication). Results: On the bright side of Self-Determination Theory (SDT), correlations revealed that perceived teacher autonomy support was positively associated with students’ basic need satisfaction and life skills development in PE. On the dark side of SDT, perceived controlling teaching was positively related to students’ basic need frustration, but not significantly related to their life skills development. Mediational analyses revealed that autonomy and relatedness satisfaction mediated the relationships between perceived teacher autonomy support and students’ development of all eight life skills. Competence satisfaction mediated the relationships between perceived teacher autonomy support and students’ development of teamwork, goal setting, and leadership skills. Conclusions: Our findings indicate that satisfaction of the needs for autonomy, competence, and relatedness are important mechanisms that in part explain the relationships between perceived teacher autonomy support and life skills development in PE. Therefore, teachers may look to promote students’ perceptions of an autonomy-supportive climate that satisfies their three basic needs and helps to develop their life skills

Mentalising skills in generic mental healthcare settings: can we make our day-to-day interactions more therapeutic?

Aims and method: Caring for patients with personality disorder is one of the biggest challenges in psychiatric work. We investigated whether mentalisation-based treatment skills (MBT-S) teaching improves clinicians' understanding of mentalising and attitudes towards personality disorder. Self-report questionnaires (Knowledge and Application of MBT (KAMQ) and Attitudes to Personality Disorder (APDQ)) were completed at baseline and after a 2-day MBT-S workshop. Results: Ninety-two healthcare professionals completed questionnaires before and after training. The mean within-participant increase in scores from baseline to end-of-programme was 11.6 points (95% CI 10.0-13.3) for the KAMQ and 4.0 points (1.8-6.2) for the APDQ. Clinical implications: MBT-S is a short intervention that is effective in improving clinicians' knowledge of personality disorder and mentalisation. That attitudes to personality disorder improved overall is encouraging in relation to the possibility of deeper learning in staff and, ultimately, improved care for patients with personality disorder. Declaration of interest: None

Circumventing qPCR inhibition to amplify miRNAs in plasma

Background: Circulating microRNAs (c-miRNAs) have be identified in saliva, urine and blood, which has led to increasing interest in their development as biomarkers for diverse diseases including cancers. One of the key advantages of c-miRNAs over other biomarkers is the ability to be amplified and quantified by quantitative PCR (qPCR). However, at phlebotomy when whole blood is dispensed into heparinized tubes, residual levels of the anti-coagulant lithium heparin may remain in the plasma and hence with RNA isolated from the plasma. This can confound the detection of c-miRNAs by qPCR because it inhibits reverse transcriptase (RT). Here we present a procedure, modified from earlier techniques, to detect c-miRNAs in plasma that improves sensitivity and streamlines performance.Findings: Treatment of total RNA isolated from human blood plasma with Bacteroides heparinase I during reverse transcription at 37°C for one hour improved sensitivity and performance of the qPCR. This is in comparison to no treatment or treatment of the RNA prior to RT, which is the current suggested method and exposes plasma to Flavobacterium heparinum heparinase I for up to 2 hours before RT. This modest alteration improved qPCR performance and resulted in lowered threshold cycles (C) for detection of the target sequence, candidate c-miRNA biomarkers, and controls. It also reduced the expense and number of processing steps, shortening the duration of the assay and minimizing exposure of RNA to elevated temperatures.Conclusion: Incorporating Bacteroides heparinase I treatment into conventional RT protocols targeting c-miRNA in plasma can be expected to expedite the discovery of biomarkers
