    BACKGROUND: A key feature of a good general practice consultation is that it is patient-centred. A number of verbal and non-verbal behaviours have been identified as important to establish a good relationship with the patient. However, the use of the computer detracts the doctor's attention away from the patient, compromising these essential elements of the consultation. Current methods to assess the consultation and the influence of the computer on them are time consuming and subjective. If it were possible to measure these quantitatively, it could provide the basis for the first truly objective way of studying the influence of the computer on the consultation. The aim was to assess whether pattern recognition software could be used to measure the influence and pattern of computer use in the consultation. If this proved possible it would provide, for the first time, an objective quantitative measure of computer use and a measure of the attention and responsiveness of the general practitioner towards the patient. METHODS: A feasibility study using pattern recognition software to analyse a consultation was conducted. A web camera, linked to a data-gathering node was used to film a simulated consultation in a standard office. Members of the research team enacted the role of the doctor and the patient, using pattern recognition software to try and capture patient-centred, non-verbal behaviour. As this was a feasibility study detailed results of the analysis are not presented. RESULTS: It was revealed that pattern recognition software could be used to analyse certain aspects of a simulated consultation. For example, trigger lines enabled the number of times the clinician's hand covered the keyboard to be counted and wrapping recorded the number of times the clinician nodded his head. It was also possible to measure time sequences and whether the movement was brief or lingering. CONCLUSION: Pattern recognition software enables movements associated with patient-centredness to be recorded. Pattern recognition software has the potential to provide an objective, quantitative measure of the influence of the computer on the consultation

    Biological and chemical contaminants by man-made activities have been serious global issue. Exposure of these contaminants beyond the limits may result in serious environmental and health problem. Therefore, it is important to develop an effective solution that can be easily utilized by mankind. One of the effective ways to overcome this problem is by using titanium dioxide (TiO2). TiO2 is a well-known photocatalyst that widely used for environmental clean-up due to its ability to decompose organic pollutant and kill bacteria. Although it is proven TiO2 has an advantage to solve this concern, its usefulness unfortunately is limited only under UV light irradiation. Therefore, the aim of this work was to investigate the potential of TiO2 that can be activated under visible light by the incorporation of metal ions (Fe, Ag, Zr and Ag-Zr). In this study, sol-gel method was employed for the synthesis of metal ions incorporated TiO2. XRD analysis revealed that all samples content biphasic anatase-brookite TiO2 of size 3 nm to 5 nm. It was found that the incorporation of these metal ions did not change the morphology of TiO2 but the crystallinity and optical properties were affected. The crystallinity of anatase in the biphasic TiO2 was found to be decreased and favored brookite formation. PL analysis showed metal ions incorporation suppressed the recombination of electron-hole pairs while the band gap energy of TiO2 (3.2 eV) was decreased by the incorporation of Fe (2.46 eV) and Ag (2.86 eV). Among this incorporation, Ag-Zr incorporated TiO2 showed highest performance for methyl orange degradation (93%) under fluorescent xxv light irradiation for 10 h. This follows by Zr-TiO2 (82%), Fe-TiO2 (75%) and Ag�TiO2 (43%). Meanwhile, the highest antibacterial performance was exhibited by Ag�TiO2. TEM images showed that E.coli bacterium was killed within 12 h after treated with Ag-TiO2. The results obtained from the fieldwork study established that Ag-Zr incorporation have excellent performances for VOC removal and antibacterial test. The VOC content after treated with Ag-Zr-TiO2 fulfilled the Industry Code of Practice on Indoor Air Quality 2010 which is lower than 3 ppm. In addition, the percentage of microbes also found to be decrease around 45 % within 5 days of monitoring

    Description and measurement of visual scanning training in Occupational Therapy for patients with visual search deficits following stroke

    Get PDF
    Executive SummaryBackgroundVisual search is a process which is integral for carrying out most activities of daily living; for example for finding utensils needed in preparing a meal or for avoiding hazards when crossing the road. This essential process is commonly disrupted by visual impairments and reduced spatial attention after stroke. Affected individuals can experience long term limitations in everyday activities due to inefficiencies in observation and visual searching. Occupational Therapists working in stroke services include visual scanning and search training within their treatment. However it is not known if the intervention is effective for improving occupational performance and visual functioning. Before the intervention can be properly evaluated for its effectiveness some essential development work is needed AimsThis project aimed to prepare for an evaluation of effectiveness of visual scanning and search training in Occupational Therapy by achieving three important steps: 1.A detailed and systematic description of the intervention delivered in the community setting2.Development and pilot testing of a process measure to quantify search performance in the home context 3.A feasibility study of the intervention delivered intensively over three weeks.MethodsTo obtain a description of the intervention a specialist Occupational Therapist in stroke, working in a community service, made video recordings of her treatment sessions delivered to five participants with visual field deficits after stroke. The recordings were analysed using a framework approach. The findings were presented to a reference group of Occupational Therapists interested in vision after stroke for validation of the description as good clinical practice. A timed room search task using keys placed in different parts of a living room over 16 trials was designed to measure search performance. Point of regard during the searches was recorded from a digital video camera worn on the participant’s head.Feasibility of the defined intervention delivered three times a week for three weeks and of the room search task administered in the home before and after the intervention was tested with nine participants. In addition a patient reported outcome measure, the Visual Functioning Questionnaire (VFQ25), was administered before and after the intervention.Summary of key findings•A detailed description of Occupational Therapy intervention for training visual scanning and search has been developed. The intervention is task specific to participants’ goal occupations and trains strategies for search using remedial activities and real tasks. The intervention was endorsed as good clinical practice by the reference group of Occupational Therapists with special interest and experience in training scanning and search in people with visual impairments after stroke.•The treatment was found to be feasible and acceptable to participants treated intensively over three weeks.•A room search task for assessing search performance proved to be feasible and demonstrated changes in the distribution and starting point of search after the intervention. However these changes in search behaviour did not always lead to increased speed or accuracy. Participants with more severe visual impairments were more efficient in searching after the treatment while some more mildly affected participants took longer to find the object.•A patient reported outcome measure was tested and found to be responsive in the sample suggesting it may be a good primary outcome measure for a clinical trial. The participants reported better visual functioning on the visual functioning questionnaire after the intervention.Recommendations for researchFurther work is needed before the intervention is evaluated in a clinical trial:Some experimental work is needed to determine the efficacy of search strategies used in the intervention. The results from our small sample suggest that strategies should be tailored to individuals’ baseline performance. For example starting the search in the blind field may be helpful in some cases, but a hindrance in others. Further work is needed to identify the most effective strategies for improving search performance in different individuals and to understand the mechanisms of the intervention for improving patients’ perceptions of their visual functioning. A measure of search performance in real world tasks would be helpful to determine the mechanism for improving function, and for understanding which patients benefit. The room search task goes some way towards this, but further work is recommended to investigate the use of new technologies to achieve more flexible and more accurate recording of point of regard during real activities of daily living.The visual functioning questionnaire,(VFQ25) would appear have potential as a primary outcome measure in a trial of clinical effectiveness of the intervention. Further research into its responsiveness and internal consistency in a larger sample of stroke participants is recommended

    Use of nonintrusive sensor-based information and communication technology for real-world evidence for clinical trials in dementia

    Cognitive function is an important end point of treatments in dementia clinical trials. Measuring cognitive function by standardized tests, however, is biased toward highly constrained environments (such as hospitals) in selected samples. Patient-powered real-world evidence using information and communication technology devices, including environmental and wearable sensors, may help to overcome these limitations. This position paper describes current and novel information and communication technology devices and algorithms to monitor behavior and function in people with prodromal and manifest stages of dementia continuously, and discusses clinical, technological, ethical, regulatory, and user-centered requirements for collecting real-world evidence in future randomized controlled trials. Challenges of data safety, quality, and privacy and regulatory requirements need to be addressed by future smart sensor technologies. When these requirements are satisfied, these technologies will provide access to truly user relevant outcomes and broader cohorts of participants than currently sampled in clinical trials

    Examining the potential public health benefit of offering STI testing to men in amateur football clubs: evidence from cross-sectional surveys

    Get PDF
    Background: In Britain, young people continue to bear the burden of sexually transmitted infections (STIs) so efforts are required, especially among men, to encourage STI testing. The SPORTSMART study trialled an intervention that sought to achieve this by offering chlamydia and gonorrhoea test-kits to men attending amateur football clubs between October and December 2012. With football the highest participation team sport among men in England, this paper examines the potential public health benefit of offering STI testing to men in this setting by assessing their sociodemographic characteristics, sexual behaviours, and healthcare behaviour and comparing them to men in the general population. Methods: Data were collected from 192 (male) members of 6 football clubs in London, United Kingdom, aged 18–44 years via a 20-item pen-and-paper self-completion questionnaire administered 2 weeks after the intervention. These were compared to data collected from 409 men of a similar age who were resident in London when interviewed during 2010–2012 for the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a national probability survey that used computer-assisted-personal-interviewing with computer-assisted-self-interview. Age standardisation and multivariable regression were used to account for sociodemographic differences between the surveys. Results: Relative to men in the general population, SPORTSMART men were younger (32.8 % vs. 21.7 % aged under 25 y), and more likely to report (all past year) at least 2 sexual partners (adjusted odds ratio, AOR: 3.25, 95 % CI: 2.15–4.92), concurrent partners (AOR: 2.05, 95 % CI: 1.39–3.02), and non-use of condoms (AOR: 2.17, 95 % CI: 1.39–3.41). No difference was observed in STI/HIV risk perception (AOR for reporting “not at all at risk” of STIs: 1.25, 95 % CI: 0.76–2.04; of HIV: AOR: 1.54, 95 % CI: 0.93–2.55), nor in reporting STI testing in the past year (AOR: 0.83, 95 % CI: 0.44–1.54), which was reported by only one in six men. Conclusions: Relative to young men in the general population, football club members who completed the SPORTSMART survey reported greater sexual risk behaviour but similar STI/HIV risk perception and STI testing history. Offering STI testing in amateur football clubs may therefore widen access to STI testing and health promotion messages for men at higher STI risk, which, given the minority currently testing and the popularity of football in England, should yield both individual and public health benefit
