Sensing of EGTA Mediated Barrier Tissue Disruption with an Organic Transistor.
Barrier tissue protects the body against external factors by restricting the passage of molecules. The gastrointestinal epithelium is an example of barrier tissue with the primary purpose of allowing the passage of ions and nutrients, while restricting the passage of pathogens and toxins. It is well known that the loss of barrier function can be instigated by a decrease in extracellular calcium levels, leading to changes in protein conformation and an increase in paracellular transport. In this study, ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetra acetic acid (EGTA), a calcium chelator, was used to disrupt the gastrointestinal epithelial barrier. The effect of EGTA on barrier tissue was monitored by a novel label-free method based on an organic electrochemical transistor (OECT) integrated with living cells and validated against conventional methods for measuring barrier tissue integrity. We demonstrate that the OECT can detect breaches in barrier tissue upon exposure to EGTA with the same sensitivity as existing methods but with increased temporal resolution. Due to the potential of low cost processing techniques and the flexibility in design associated with organic electronics, the OECT has great potential for high-throughput, disposable sensing and diagnostics

Investigating the enabling factors influencing occupational therapistsâ adoption of assisted living technology
Introduction
Research into technology adoption has focused on older adultsâ motivations, with less exploration of the perspective of healthcare providers, including occupational therapists, who are often described as the gatekeepers to assisted living technology.
Method
This qualitative study utilized semi-structured interviews and focus groups with 20 occupational therapists in England and Scotland. The goal was to identify those enabling factors necessary for occupational therapists to adopt assisted living technology.
Results
Five themes emerged regarding the enablers needed to support the adoption of assisted living technology by occupational therapists, including: (1) a positive clientâtherapist relationship; (2) affordability; (3) time; (4) increased awareness, education, and training; and (5) usability features of the assisted living technology.
Conclusion
With an aging population and the increasing role that technology is playing globally in older adultsâ lives, it has never been more important for occupational therapists to harness the potential of new, developing, and existing technologies to support people to live and age as well as possible. To accomplish this, however, requires that occupational therapists are equipped with the time, training, and education necessary to offer their clients assisted living technologies that are client-centered, usable, and affordabl
Webâbased Weight Management Programs in an Integrated Health Care Setting: A Randomized, Controlled Trial
Objective : To assess the efficacy of a Webâbased tailored behavioral weight management program compared with Webâbased informationâonly weight management materials. Research Methods and Procedures : Participants, 2862 eligible overweight and obese (BMI = 27 to 40 kg/m 2 ) members from four regions of Kaiser Permanente's integrated health care delivery system, were randomized to receive either a tailored expert system or informationâonly Webâbased weight management materials. Weight change and program satisfaction were assessed by selfâreport through an Internetâbased survey at 3â and 6âmonth followâup periods. Results : Significantly greater weight loss at followâup was found among participants assigned to the tailored expert system than among those assigned to the informationâonly condition. Subjects in the tailored expert system lost a mean of 3 ± 0.3% of their baseline weight, whereas subjects in the informationâonly condition lost a mean of 1.2 ± 0.4% ( p < 0.0004). Participants were also more likely to report that the tailored expert system was personally relevant, helpful, and easy to understand. Notably, 36% of enrollees were AfricanâAmerican, with enrollment rates higher than the general proportion of African Americans in any of the study regions. Discussion : The results of this large, randomized control trial show the potential benefit of the Webâbased tailored expert system for weight management compared with a Webâbased informationâonly weight management program.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/93691/1/oby.2006.34.pd
Using text messages to support recovering substance misusers
YesBackground: The use of digital technology in health and social care is developing rapidly. It is
promoted in UK policy and research which suggests varied results surrounding its implementation
and outcomes. Introduction: This article aimed to test the implementation and outcomes of a
short messaging service sent to a dedicated phone. The target cohort were drug treatment clients
in two sites in Northern England. Materials and methods: Through staff focus groups and
interviews with a small cohort of clients, the implementation and perceptions of the system were
examined. Results: Nineteen participants were recruited to site 1 (15 male, 4 female, average
age=37.7 years) and 12 participants were recruited to site 2 (9 male, 3 female, average age=40.3
years). One outcome that was of interest was well-being in treatment which, in this study, was
described as an overall sense of feeling better rather than just focusing on the rehabilitation
aspect of the programme. Other outcomes included: the successful completion of treatment and
any relapse or associated reported drug use. Discussion: The system shows some evidence of
its âsocial actorâ role; however, its implementation was hindered by staff citing that it called for
increased resources. For future implementation the use of clientâs own phones may be considered
which may help to embed the system more fully in recovery planning and targeting clients at a
different treatment stage. Conclusions: Despite some indications of positive results for clients
and a perception that the system may have value as an addition to existing clinical interventions,
more evaluation is required to determine whether this system can be implemented in a drug
treatment setting
A Review of Surgical Informed Consent: Past, Present, and Future. A Quest to Help Patients Make Better Decisions
Contains fulltext :
87422.pdf (publisher's version ) (Closed access)BACKGROUND: Informed consent (IC) is a process requiring a competent doctor, adequate transfer of information, and consent of the patient. It is not just a signature on a piece of paper. Current consent processes in surgery are probably outdated and may require major changes to adjust them to modern day legislation. A literature search may provide an opportunity for enhancing the quality of the surgical IC (SIC) process. METHODS: Relevant English literature obtained from PubMed, Picarta, PsycINFO, and Google between 1993 and 2009 was reviewed. RESULTS: The body of literature with respect to SIC is slim and of moderate quality. The SIC process is an underestimated part of surgery and neither surgeons nor patients sufficiently realize its importance. Surgeons are not specifically trained and lack the competence to guide patients through a legally correct SIC process. Computerized programs can support the SIC process significantly but are rarely used for this purpose. CONCLUSIONS: IC should be integrated into our surgical practice. Unfortunately, a big gap exists between the theoretical/legal best practice and the daily practice of IC. An optimally informed patient will have more realistic expectations regarding a surgical procedure and its associated risks. Well-informed patients will be more satisfied and file fewer legal claims. The use of interactive computer-based programs provides opportunities to improve the SIC process.1 juli 201
Video-calls to reduce loneliness and social isolation within care environments for older people: an implementation study using collaborative action research
Background Older people in care may be lonely with insufficient contact if families are unable to visit. Face-to-face contact through video-calls may help reduce loneliness, but little is known about the processes of engaging people in care environments in using video-calls. We aimed to identify the barriers to and facilitators of implementing video-calls for older people in care environments. Methods A collaborative action research (CAR) approach was taken to implement a video-call intervention in care environments. We undertook five steps of recruitment, planning, implementation, reflection and re-evaluation, in seven care homes and one hospital in the UK. The video-call intervention ‘Skype on Wheels’ (SoW) comprised a wheeled device that could hold an iPad and handset, and used Skype to provide a free video-call service. Care staff were collaborators who implemented the intervention within the care-setting by agreeing the intervention, recruiting older people and their family, and setting up video-calls. Field notes and reflective diaries on observations and conversations with staff, older people and family were maintained over 15 months, and analysed using thematic analysis. Results Four care homes implemented the intervention. Eight older people with their respective social contacts made use of video-calls. Older people were able to use SoW with assistance from staff, and enjoyed the use of video-calls to stay better connected with family. However five barriers towards implementation included staff turnover, risk averseness, the SoW design, lack of family commitment and staff attitudes regarding technology. Conclusions The SoW intervention, or something similar, could aid older people to stay better connected with their families in care environments, but if implemented as part of a rigorous evaluation, then co-production of the intervention at each recruitment site may be needed to overcome barriers and maximise engagement
