Comparison between audio and tactile systems for delivering simple navigational information to visually impaired pedestrians

Many of the current GPS (Global Positioning Systems) navigation aids use an audio method to deliver navigation information to the user. For the visually impaired person this method can be problematic. The visually impaired pedestrian relies heavily on information contained within the ambient sound environment; for location and orientation information, navigation information, and importantly, safety information. In this paper we present the design of an innovative tactile interface and verification of results obtained through experimental trials. This pilot study compared the efficiency of the tactile interface, to an audio method of delivering simple navigational information. The findings indicate that the tactile interface could be used successfully by blind and sighted pedestrians and may offer advantages over auditory interfaces

An ounce of prevention is worth a pound of cure - universal health coverage to strengthen health security

The Sustainable Development Goal 3 targets aim to ensure that individuals achieve universal health coverage and that the capacity of countries, to identify early warnings, implement risk reduction plans and to respond and manage national and global health risks including emerging infectious diseases out-breaks is strengthened. Funding for the achievement of these outcomes can be erratic and weak healthcare systems do not cope well with the vagaries of fluctuating economies. Universal health coverage is achievable with formulated social health insurance programs that ensure consistent and predictable financial flows. This article deliberates the situation in the Asia Pacific region considering how funding the elimination of infectious diseases (specifically malaria) can facilitate a strengthening of weak health systems, which in turn will build economic potency and health security in the region

Worldwide variation in the relative importance of hepatitis B and hepatitis C viruses in hepatocellular carcinoma: a systematic review

We combined information published worldwide on the seroprevalence of hepatitis B surface antigen (HbsAg) and antibodies against hepatitis C virus (anti-HCV) in 27 881 hepatocellular carcinomas (HCCs) from 90 studies. A predominance of HBsAg was found in HCCs from most Asian, African and Latin American countries, but anti-HCV predominated in Japan, Pakistan, Mongolia and Egypt. Anti-HCV was found more often than HBsAg in Europe and the United States

Barriers to kidney transplants in Indonesia : a literature review

Background: People living with chronic kidney disease will require renal dialysis or a kidney transplant to maintain life. Although Indonesia has a developing healthcare industry, Indonesia\u27s kidney transplant rates are lower than comparable nations.Purpose: To explore the healthcare literature to identify barriers to kidney transplants in particular in relation to Indonesia.Methods: Healthcare databases were searched (CINAHL, Medline, EBSCOhostEJS, Blackwell Synergy, Web of Science, PubMed, Google Scholar and Proquest 5000) using the search terms: transplant, kidney disease, renal, dialysis, haemodialysis, Indonesia and nursing. The search was limited to English and Indonesian language data sources from 1997 to 2007. Reference lists of salient academic articles were hand searched.Results: The results of our search identified six articles that met our criteria. Costs are the major barrier to kidney transplant in Indonesia, followed by cultural beliefs, perception of the law, lack of information and lack of infrastructure. In addition, kidney disease prevention strategies are required.Conclusions: There are many complex socio-economic, geographical, legal, cultural and religious factors that contribute to low kidney transplant rates in Indonesia. Although an increase in transplantation rates will require strategies from various agencies, healthcare professionals, including nurses, can play a role in overcoming some barriers. Community education programmes, improving their own education levels and by increasing empowerment in nursing we may contribute to improved kidney transplant rates in Indonesia.<br /

Health promotion services for lifestyle development within a UK hospital – Patients' experiences and views

<p>Abstract</p> <p>Background</p> <p>UK public health policy requires hospitals to have in place health promotion services which enable patients to improve their health through adopting healthy behaviours, i.e. health education. This study investigated hospitalised patients' experiences of health education for smoking, alcohol use, diet, physical activity, and weight, and their views concerning the appropriateness of hospitals as a setting for the delivery of health education services.</p> <p>Methods</p> <p>Recently discharged adult hospital patients (n = 322) were sent a questionnaire asking about their smoking, alcohol use, diet, physical activity, and weight. For each of these risk factors, participants were asked whether they agreed with screening for the risk factor, whether they received health education, whether it was "helpful", and if they wanted to change their behaviour. Participants were also asked a set of general questions concerning health education within hospitals.</p> <p>Results</p> <p>190 patients responded (59%). Over 80% agreed with screening for all risk factors. 80% of smokers, 52% consuming alcohol above recommended limits, 86% of obese, 66% consuming less than five fruit and vegetables a day, and 61% of physically inactive participants wanted to change their respective behaviour. However only a third reported receiving health education. While over 60% of patients wanted health education around discharge, the majority of those receiving health education did so at admission. The majority agreed that "hospital is a good place for patients to receive" health education (87%) and that "the hospital should provide patients with details of community organisations that provide" health education (83%). Only a minority (31%) reported a preference for health education from their GP instead of hospital.</p> <p>Conclusion</p> <p>While the delivery of health education to patients within hospital was poor, hospitals are viewed by patients as an appropriate, and in some cases preferred setting for the screening of risk factors and delivery of health education.</p

Gaining consensus on family carer needs when caring for someone dying at home to develop the Carers' Alert Thermometer (CAT): a modified Delphi study

Aim To report a multi-phase modified Delphi study conducted with carers and professionals to identify the priority areas for inclusion in an alert screening tool for carers providing support to someone dying at home. Background Internationally, there is a growing emphasis on increasing choice for patients who wish to die at home which relies heavily on care provided by the unpaid family carers. Family carers can have high levels of unmet needs comprising their psychological and physical health and their ability to provide effective care and support. Development of an alert tool to identify carers' needs in everyday practice required identification and consensus of the priority areas of need for inclusion. Design Multi-phase modified Delphi study and instrument development. Method Qualitative and quantitative data collection took place between 2011–2013 with 111 carers and 93 professionals to identify carers' needs and gain consensus on the priority areas for inclusion in the alert tool. An expert panel stage and final evidence review post-Delphi were used. Results The Delphi panels had high levels of agreement and consensus. Ten areas of carer need across two themes of ‘the current caring situation’ and ‘the carer's own health and well-being’ were prioritized for inclusion in the alert tool. An optional end-of-life planning question was included following the final stages. Conclusions The results provide evidence of carers' needs to be assessed, areas for consideration in the education of those who support carers and someone dying at home and targeting of services, while demonstrating the usefulness and adaptability of the Delphi method

The fields of HIV and disability: past, present and future

This article provides an historic overview of the fields of disability and HIV. We describe this area of concern in terms of "fields" versus "a single field" because of the two related but distinct trends that have evolved over time. The first field involves people living with HIV and their experiences of disability, disablement and rehabilitation brought on by the disease and its treatments. The second involves people with disabilities and their experiences of vulnerability to and life with HIV. These two fields have evolved relatively independently over time. However, in the final section of this article, we argue that the divide between these fields is collapsing, and that this collapse is beginning to produce a new understanding about shared concerns, cross-field learning and the mutual benefits that might be realized from integrating policy and programmatic responses. We close by identifying directions that we expect these merging fields to take in the coming years

Global mapping of highly pathogenic avian influenza H5N1 and H5Nx clade 2.3.4.4 viruses with spatial cross-validation.

Global disease suitability models are essential tools to inform surveillance systems and enable early detection. We present the first global suitability model of highly pathogenic avian influenza (HPAI) H5N1 and demonstrate that reliable predictions can be obtained at global scale. Best predictions are obtained using spatial predictor variables describing host distributions, rather than land use or eco-climatic spatial predictor variables, with a strong association with domestic duck and extensively raised chicken densities. Our results also support a more systematic use of spatial cross-validation in large-scale disease suitability modelling compared to standard random cross-validation that can lead to unreliable measure of extrapolation accuracy. A global suitability model of the H5 clade 2.3.4.4 viruses, a group of viruses that recently spread extensively in Asia and the US, shows in comparison a lower spatial extrapolation capacity than the HPAI H5N1 models, with a stronger association with intensively raised chicken densities and anthropogenic factors
