To evaluate the feasibility and safety of a home-based exercise programme for people with Alzheimer's disease, and to provide preliminary evidence of programme effectiveness in improving balance and mobility and reducing falls risk. A randomized controlled trial. Community. Forty people with mild to moderate Alzheimer's disease (mean age 81.9, SD 5.72; 62.5% female). Participants were randomized to a six-month home-based individually tailored balance, strengthening and walking exercise programme (physiotherapist) or a six-month home-based education programme (control) (occupational therapist). Both programmes provided six home-visits and five follow-up phone calls. Balance, mobility, falls and falls risk were measured at baseline and programme completion. Intention-to-treat analysis using a generalized linear model with group allocation as a predictor variable was performed to evaluate programme effectiveness. Feasibility and adverse events were systematically recorded at each contact. Fifty-eight per cent of the exercise group finished the programme, completing an average of 83% of prescribed sessions, with no adverse events reported. Functional Reach improved significantly (P = 0.002) in the exercise group (mean (SD), 2.28 (4.36)) compared to the control group (-2.99 (4.87)). Significant improvement was also observed for the Falls Risk for Older People - Community score (P = 0.008) and trends for improvement on several other balance, mobility, falls and falls risk measures for the exercise group compared to the control group. The exercise programme was feasible and safe and may help improve balance and mobility performance and reduce falls risk in people with Alzheimer's disease.

Innovative effective smoking cessation interventions are required to appeal to those who are not accessing traditional cessation services. Mobile phones are widely used and are now well integrated into the daily lives of many, particularly young adults. Mobile phones are a potential medium for the delivery of health programmes such as smoking cessation. To determine whether mobile phone-based interventions are effective at helping people who smoke, to quit. We searched MEDLINE, EMBASE, Cinahl, PsycINFO, The Cochrane Library, the National Research Register and the ClinicalTrials register, with no restrictions placed on language or publication date. We included randomized or quasi-randomized trials. Participants were smokers of any age who wanted to quit. Studies were those examining any type of mobile phone-based intervention. This included any intervention aimed at mobile phone users, based around delivery via mobile phone, and using any functions or applications that can be used or sent via a mobile phone. Information on the specified quality criteria and methodological details was extracted using a standardised form. Participants who dropped out of the trials or were lost to follow up were considered to be smoking. Meta-analysis of the included studies was undertaken using the Mantel-Haenszel Risk Ratio fixed-effect method provided that there was no evidence of substantial statistical heterogeneity as assessed by the I(2) statistic. Where meta-analysis was not possible, summary and descriptive statistics are presented. Four studies were excluded as they were small non-randomized feasibility studies, and two studies were excluded because follow up was less than six months. Four trials (reported in five papers) are included: a text message programme in New Zealand; a text message programme in the UK; and an Internet and mobile phone programme involving two different groups in Norway. The different types of interventions are analysed separately. When combined by meta-analysis the text message programme trials showed a significant increase in short-term self-reported quitting (RR 2.18, 95% CI 1.80 to 2.65). However, there was considerable heterogeneity in long-term outcomes, with the much larger trial having problems with misclassification of outcomes; therefore these data were not combined. When the data from the Internet and mobile phone programmes were pooled we found statistically significant increases in both short and long-term self-reported quitting (RR 2.03, 95% CI 1.40 to 2.94). The current evidence shows no effect of mobile phone-based smoking cessation interventions on long-term outcome. While short-term results are positive, more rigorous studies of the long-term effects of mobile phone-based smoking cessation interventions are needed.

To compare a non-programmable and a programmable insulin external pump using regular insulin on glycemic stability, the risk of severe hypoglycemia and metabolic control in type 1 diabetic patients. Ten type 1 diabetic patients were involved in a randomized, crossover study comparing two periods of 3 months with continuous subcutaneous insulin infusion (CSII) either with a non-programmable insulin pump or a programmable insulin pump. Comparisons were made among mean blood glucose values before and after meals, at bedtime and at 2: 00 a.m.; the risk of severe hypoglycemia assessed by the low blood glucose index (LBGI); and HbA1c. Mean average blood glucose (BG) measurements were significantly lower with the programmable in comparison with the non-programmable insulin pump (respectively 157+/-78 vs. 165+/-79, p=0.034). While postprandial values for BG were not different between the two pumps, the use of the programmable pump resulted in a significant decrease in mean preprandial BG levels (140+/-68 vs. 150+/-73 mg/dl p=0.039). Conversely mean BG level was lower at 2 a.m. with the non-prgrammable pump (125+/-81 vs. 134 +/-93 mg/dl, p=0.02) but with a higher incidence of hypoglycemia. Mean LBGI was comparable with the two pumps (3.1+/-8.6 vs. 2.8+/-6.9, p=0.1). There was a 0.2% decrease in HbA1c during the programmable pump period that did not reach statistical significance (p=0.37). The present study suggests that programmable external insulin pumps, although more complex and more expensive than non-programmable insulin pumps, significantly reduce fasting glycemia during the day without increasing the risk of severe hypoglycemia and are safer during the night.

The increased penetration of mobile devices has created opportunities in the health sector and led to emerging of mobile health systems. As much as the mobile health systems have registered tremendous progress, they have been faced with privacy and usability issues. Due to the sensitivity of health information, there is an ethical need to equip mobile health systems with adequate privacy measures. However, these systems should also be useable by the intended users. Even though many researchers are working on solutions, the issues still persist. External factors such as cultural differences have also contributed to the issues, yet they have been under researched. In this article, we conduct a systematic literature review of 22 articles, categorize and present privacy and usability issues and possible solutions. We then discuss the relevance and implications of external factors to the findings on privacy and usability. We end with recommendations to address these external factors.

Mobile high-performance computing (HPC) for synthetic aperture radar signal processing

The importance of mobile high-performance computing has emerged in numerous battlespace applications at the tactical edge in hostile environments. Energy efficient computing power is a key enabler for diverse areas ranging from real-time big data analytics and atmospheric science to network science. However, the design of tactical mobile data centers is dominated by power, thermal, and physical constraints. Presently, it is very unlikely to achieve required computing processing power by aggregating emerging heterogeneous many-core processing platforms consisting of CPU, Field Programmable Gate Arrays and Graphic Processor cores constrained by power and performance. To address these challenges, we performed a Synthetic Aperture Radar case study for Automatic Target Recognition (ATR) using Deep Neural Networks (DNNs). However, these DNN models are typically trained using GPUs with gigabytes of external memories and massively used 32-bit floating point operations. As a result, DNNs do not run efficiently on hardware appropriate for low power or mobile applications. To address this limitation, we proposed for compressing DNN models for ATR suited to deployment on resource constrained hardware. This proposed compression framework utilizes promising DNN compression techniques including pruning and weight quantization while also focusing on processor features common to modern low-power devices. Following this methodology as a guideline produced a DNN for ATR tuned to maximize classification throughput, minimize power consumption, and minimize memory footprint on a low-power device.

We conducted a community-based anti-obesity programme using mobile phone short message service (SMS) messaging. A total of 927 participants were recruited and visited a public health centre for initial assessment. Mobile phones were used to deliver short messages about diet, exercise and behaviour modification once a week. After a 12-week anti-obesity programme they visited the public health centre again. Four hundred and thirty-three subjects (47%) successfully completed their weight control programme. There were mean reductions of weight, waist circumference and body mass index of 1.6 kg (P < 0.001), 4.3 cm (P < 0.001) and 0.6 kg/m(2) (P < 0.001), respectively. Over two-thirds of the subjects had a reduction in waist circumference of 5-7.5 cm. A post-intervention survey showed that the majority of participants were satisfied with the weekly SMS messages and information brochures delivered by post. SMS messaging may be an effective method of behaviour modification in weight control and anti-obesity health education programmes when promoted by community health centres.

The expanded programme of immunization was established in Cambodia in 1986. In 2002, 67% of eligible children were immunized, despite significant health sector and macro-economic financial constraints. A financial sustainability planning process for immunization was introduced in 2002, in order to mobilize national and international resources in support of the achievement of child health objectives. The aim of this paper is to outline this process, describe its early impact as an advocacy tool and recommend additional strategies for mobilizing additional resources for health. The methods of financial sustainability planning are described, including the advocacy strategies that were applied. Analysis of financial sustainability planning results indicates rising programme costs associated with new vaccine introduction and new technologies. Despite this, the national programme has demonstrated important early successes in using financial sustainability planning to advocate for increased mobilization of national and international sources of funding for immunization. The national immunization programme nevertheless faces formidable system and financial challenges in the coming years associated with rising costs, potentially diminishing sources of international assistance, and the developing role of sub-national authorities in programme management and financing.

Patients who are sick enough to be admitted to an intensive care unit (ICU) commonly experience symptoms of psychological distress after discharge, yet few effective therapies have been applied to meet their needs. Pilot randomised clinical trial with 3-month follow-up conducted at two academic medical centres. Adult (≥18 years) ICU patients treated for cardiorespiratory failure were randomised after discharge home to 1 of 3 month-long interventions: a self-directed mobile app-based mindfulness programme; a therapist-led telephone-based mindfulness programme; or a web-based critical illness education programme. Among 80 patients allocated to mobile mindfulness (n=31), telephone mindfulness (n=31) or education (n=18), 66 (83%) completed the study. For the primary outcomes, target benchmarks were exceeded by observed rates for all participants for feasibility (consent 74%, randomisation 91%, retention 83%), acceptability (mean Client Satisfaction Questionnaire 27.6 (SD 3.8)) and usability (mean Systems Usability Score 89.1 (SD 11.5)). For secondary outcomes, mean values (and 95% CIs) reflected clinically significant group-based changes on the Patient Health Questionnaire depression scale (mobile (-4.8 (-6.6, -2.9)), telephone (-3.9 (-5.6, -2.2)), education (-3.0 (-5.3, 0.8)); the Generalized Anxiety Disorder scale (mobile -2.1 (-3.7, -0.5), telephone -1.6 (-3.0, -0.1), education -0.6 (-2.5, 1.3)); the Post-Traumatic Stress Scale (mobile -2.6 (-6.3, 1.2), telephone -2.2 (-5.6, 1.2), education -3.5 (-8.0, 1.0)); and the Patient Health Questionnaire physical symptom scale (mobile -5.3 (-7.0, -3.7), telephone -3.7 (-5.2, 2.2), education -4.8 (-6.8, 2.7)). Among ICU patients, a mobile mindfulness app initiated after hospital discharge demonstrated evidence of feasibility, acceptability and usability and had a similar impact on psychological distress and physical symptoms as a therapist-led programme. A larger trial is warranted to formally test the efficacy of this approach. Results, NCT02701361. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

External Quality Assessment (EQA) surveys performed by the World Health Organization Regional Office for Africa (WHO AFRO) revealed the need for the strengthening of public health microbiology laboratories, particularly for testing of epidemic-prone diseases in the African Region. These surveys revealed common issues such as supply chain management, skilled personnel, logistical support and overall lack of quality standards. For sustainable improvements to health systems as well as global health security, deficiencies identified need to be actively corrected through robust quality assurance programmes and implementation of laboratory quality management systems. Given all the pathogens of public health importance, an external quality assessment programme with a focus on vaccine-preventable diseases and emerging and re-emerging dangerous pathogens is important, and should not be stand-alone, but integrated within laboratory networks as seen in polio, measles, yellow fever and rubella. In 2015, WHO AFRO collaborated with the US Centers for Disease Control and Prevention, the London School of Hygiene & Tropical Medicine and partners in a series of consultations with countries and national and regional EQA providers for the development of quality assurance models to support HIV point-of-care testing and monitoring. These consultations revealed similar challenges as seen in the WHO AFRO surveys. WHO AFRO brought forth its experience in implementing quality standards for health programmes, and also opened discussions on how lessons learned through such established programmes can be utilised to supporting and strengthening the introduction of early infant diagnosis of HIV and viral load point-of-care testing. An optimised external quality assessment programme will impact the ability of countries to meet core capacities, providing improved quality management systems, improving the confidence of diagnostic network services in Africa, and including capacities to detect events of international public health importance.

We examined whether mobility, migrant status, and risk environments are associated with sexually transmitted infections (STIs) and HIV risk behaviors (e.g. sex trading, multiple partners, and unprotected sex). We used Respondent Driven Sampling (RDS) to recruit external male migrant market vendors from Kyrgyzstan, Uzbekistan, and Tajikistan as well internal migrant and non-migrant market vendors from Kazakhstan. We conducted multivariate logistic regressions to examine the effects of mobility combined with the interaction between mobility and migration status on STIs and sexual risk behaviors, when controlling for risk environment characteristics. Mobility was associated with increased risk for biologically-confirmed STIs, sex trading, and unprotected sex among non-migrants, but not among internal or external migrants. Condom use rates were low among all three groups, particularly external migrants. Risk environment factors of low-income status, debt, homelessness, and limited access to medical care were associated with unprotected sex among external migrants. Study findings underscore the role mobility and risk environments play in shaping HIV/STI risks. They highlight the need to consider mobility in the context of migration status and other risk environment factors in developing effective prevention strategies for this population.

In this article, we discuss qualitative findings basing on the experiences of refugee women living in Melbourne, Australia, who participated in a peer support training programme and received a free mobile phone. We pay attention to social support as a health enhancing strategy and empowerment that occurred among the participants. Participation in peer support groups and access to a mobile phone were beneficial for the women. Peer support functioned as social support among group members. The programme allowed the women to be connected to their families and the wider communities and assisted them to access health care and other settlement aspects with greater ease. It also increased personal empowerment among the women. Our programme shows that by tapping on community resources to ameliorate personal or resettlement issues, the burden on service providers can be reduced. Our findings also offer a model for future research and programmes regarding refugee people elsewhere. © The Author 2015. Published by Oxford University Press. All rights reserved.

Gunn, Hilary; Endacott, Ruth; Haas, Bernhard; Marsden, Jonathan; Freeman, Jennifer

2017-08-07

To utilise stakeholder input to inform the structure, format and approach of a multiple sclerosis (MS) balance, safe mobility and falls management programme. Using a three-round nominal group technique, participants individually rated their agreement with 20 trigger statements, followed by a facilitated group discussion and re-rating. Three mixed groups included service users (n = 15) and providers (n = 19). Quantitative analysis determined agreement, whilst qualitative responses were analysed thematically. Median scores for each of the 20 trigger statements did not change significantly over sequential rounds, however, deviations around the medians indicated more agreement amongst participants over time. Key recommendations were: Aims and approach: The programme should be tailored to the needs of people with MS. Falls and participation-based outcomes are equally important. Structure and format: The programme should balance expected burden and anticipated benefit, moving away from models requiring weekly attendance and promoting and supporting self-efficacy. Optimising engagement: Support to maintain engagement and intensity of practice over the long term is essential. Sustainability: Adequate funding is necessary. Staff should have MS specific knowledge and experience. Participants collaboratively identified critical components of a MS balance, safe mobility and falls management programme. They also highlighted the importance of a collaborative, user-centred, MS-specific approach. Implications for Rehabilitation People with multiple sclerosis need condition-specific interventions focussed on maximising balance and safe mobility and reducing falls. Programme design should support self-efficacy and flexible engagement. Adequate support and funding are seen as essential by both service users and providers.

Shoulder problems are highly prevalent among elite handball players. Reduced glenohumeral rotation, external rotation weakness and scapula dyskinesis have been identified as risk factors. Evaluate the effect of an exercise programme designed to reduce the prevalence of shoulder problems in elite handball. 45 elite handball teams (22 female teams, 23 male teams, 660 players) were cluster randomised (22 teams, 331 players in the intervention group, 23 teams, 329 players in the control group) and followed for 1 competitive season (7 months). The Oslo Sports Trauma Research Center (OSTRC) Shoulder Injury Prevention Programme, an exercise programme to increase glenohumeral internal rotation, external rotation strength and scapular muscle strength, as well as improve kinetic chain and thoracic mobility, was delivered by coaches and captains 3 times per week as a part of the handball warm-up. The main outcome measures, prevalence of shoulder problems and substantial shoulder problems, were measured monthly. The average prevalence of shoulder problems during the season was 17% (95% CI 16% to 19%) in the intervention group and 23% (95% CI 21% to 26%) in the control group (mean difference 6%). The average prevalence of substantial shoulder problems was 5% (95% CI 4% to 6%) in the intervention group and 8% (95% CI 7% to 9%) in the control group (mean difference 3%). Using generalised estimating equation models, a 28% lower risk of shoulder problems (OR 0.72, 95% CI 0.52 to 0.98, p=0.038) and 22% lower risk of substantial shoulder problems (OR 0.78, 95% CI 0.53 to 1.16, p=0.23) were observed in the intervention group compared with the control group. The OSTRC Shoulder Injury Prevention Programme reduced the prevalence of shoulder problems in elite handball and should be included as a part of the warm-up. ISRCTN96217107.

2014-01-01

Adherence to antiretroviral treatment (ART) is critical to maintaining health and good clinical outcomes in people living with HIV/AIDS. To address poor treatment adherence, low-cost interventions using mobile communication technology are being studied. While there are some studies that show an effect of mobile phone reminders on adherence to ART, none has reported on the costs of such reminders for national AIDS programmes. This paper aims to study the costs of mobile phone reminder strategies (mHealth interventions) to support adherence in the context of India's National AIDS Control Program (NACP). The study was undertaken at two tertiary level teaching hospitals that implement the NACP in Karnataka state, South India. Costs for a mobile phone reminder application to support adherence, implemented at these sites (i.e. weekly calls, messages or both) were studied. Costs were collected based on the concept of avoidable costs specific to the application. The costs that were assessed were one-time costs and recurrent costs that included fixed and variable costs. A sequential procedure for costing was used. Costs were calculated at national-programme level, individual ART-centre level and individual patient level from the NACP's perspective. The assessed costs were pooled to obtain an annual cost per patient. The type of application, number of ART centres and number of patients on ART were varied in a sensitivity analysis of costs. The Indian NACP would incur a cost of between 79 and 110 INR (USD 1.27-1.77) per patient per year, based on the type of reminder, the number of patients on ART and the number of functioning ART centres. The total programme costs for a scale-up of the mHealth intervention to reach the one million patients expected to be on treatment by 2017 is estimated to be 0.36% of the total five-year national-programme budget. The cost of the mHealth intervention for ART-adherence support in the context of the Indian NACP is low and is facilitated by the low cost of mobile communication in the country. Extending the use of mobile communication applications beyond adherence support under the national programme could be done relatively inexpensively.

Methods We used Respondent Driven Sampling (RDS) to recruit external male migrant market vendors from Kyrgyzstan, Uzbekistan, and Tajikistan as well internal migrant and non-migrant market vendors from Kazakhstan. We conducted multivariate logistic regressions to examine the effects of mobility combined with the interaction between mobility and migration status on STIs and sexual risk behaviors, when controlling for risk environment characteristics. Results Mobility was associated with increased risk for biologically-confirmed STIs, sex trading, and unprotected sex among non-migrants, but not among internal or external migrants. Condom use rates were low among all three groups, particularly external migrants. Risk environment factors of low-income status, debt, homelessness, and limited access to medical care were associated with unprotected sex among external migrants. Conclusion Study findings underscore the role mobility and risk environments play in shaping HIV/STI risks. They highlight the need to consider mobility in the context of migration status and other risk environment factors in developing effective prevention strategies for this population. PMID:26967159

Objective To assess the time to publication of primary research and evidence syntheses funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) Programme published as a monograph in Health Technology Assessment and as a journal article in the wider biomedical literature. Study design Retrospective cohort study. Setting Primary research and evidence synthesis projects funded by the HTA Programme were included in the cohort if they were registered in the NIHR research programmes database and was planned to submit the draft final report for publication in Health Technology Assessment on or before 9 December 2011. Main outcome measures The median time to publication and publication at 30 months in Health Technology Assessment and in an external journal were determined by searching the NIHR research programmes database and HTA Programme website. Results Of 458 included projects, 184 (40.2%) were primary research projects and 274 (59.8%) were evidence syntheses. A total of 155 primary research projects had a completion date; the median time to publication was 23 months (26.5 and 35.5 months to publish a monograph and to publish in an external journal, respectively) and 69% were published within 30 months. The median time to publication of HTA-funded trials (n=126) was 24 months and 67.5% were published within 30 months. Among the evidence syntheses with a protocol online date (n=223), the median time to publication was 25.5 months (28 months to publication as a monograph), but only 44.4% of evidence synthesis projects were published in an external journal. 65% of evidence synthesis studies had been published within 30.0 months. Conclusions Research funded by the HTA Programme publishes promptly. The importance of Health Technology Assessment was highlighted as the median time to publication was 9 months shorter for a monograph than an external journal article. PMID:24285634

To evaluate the effects of a home-based balance training programme using visual feedback (Nintendo Wii Fit game with balance board) on balance and functional abilities in subjects with Parkinson's disease, and to compare the effects with a group of paired healthy subjects. Ten subjects with moderate Parkinson's disease and 8 healthy elderly subjects. Subjects participated in a 6-week home-based balance training programme using Nintendo Wii Fit and balance board. Baseline measures were taken before training for the Sit-to-Stand test (STST), Timed-Up-and-Go (TUG), Tinetti Performance Oriented Mobility Assessment (POMA), 10-m walk test, Community Balance and Mobility assessment (CBM), Activities-specific Balance and Confidence scale (ABC), unipodal stance duration, and a force platform. All measurements were taken again after 3 and 6 weeks of training. The Parkinson's disease group significantly improved their results in TUG, STST, unipodal stance, 10-m walk test, CBM, POMA and force platform at the end of the 6-week training programme. The healthy subjects group significantly improved in TUG, STST, unipodal stance and CBM. This pilot study suggests that a home-based balance programme using Wii Fit with balance board could improve static and dynamic balance, mobility and functional abilities of people affected by Parkinson's disease.

The aim of this study was to verify the efficacy of two pencil-and-paper trainings empowering numerical and visuo-spatial abilities in Italian five-year-old kindergarteners. Specifically, the trainings were respectively carried out by the curricular teacher or by an external trainer. The former received a specific training in order to use the psychoeducational programmes with her pupils, whereas the latter received a specific education about the role of numerical and visuo-spatial abilities for school achievement and she was also trained to use psychoeducational trainings in kindergarten schools. At pre-test and post-test nonverbal functions and numeracy knowledge were assessed through a battery of standardized tests. The results show that both the numerical psychoeducational programme and the visuo-spatial one are useful tools to enhance mathematical achievements in kindergarteners. However, when the trainings were proposed by the external trainer, the efficacy of the psychoeducational programmes was more significant. These outcomes seem to be related both to the expertise and the novelty effect of the external trainer on the classroom.

Role of inspectors in external review mechanisms: criteria for selection, training and appraisal.

PubMed

Plebani, M

2001-07-20

There is a wide consensus that an external review mechanism, both in the form of a peer review, accreditation and certification according to the ISO 9000 series, is more than its standards. The survey process, the role of inspectors and standard interpretation contribute to the essence of the programme itself. Above all, the criteria used for the selection, training and appraisal of inspectors are of paramount importance. While the ISO norms do not require certification bodies to employ "peer reviewers" for the healthcare sector, experience in this sector is the main criterion for recruiting inspectors in accreditation and peer review programmes. However, the ISO/IEC Guide 58, for the setting up and operation of a laboratory accreditation body, specifies that inspectors should have appropriate technical knowledge of the specific calibrations, tests or types of calibration or tests for which accreditation is sought. Training, updating and assessment of inspectors are clearly defined under ISO, but are also systematic under accreditation programmes. Part-time inspectors who are professionals currently practising in a healthcare facility and are in touch with the day-to-day work reality are preferred for accreditation programmes which have self-regulation, education and quality improvement as their main concerns, while full-time and external inspectors are used in external review mechanisms with registration and certification as their main concerns. As well as harmonising the standards for accreditation, it is important to obtain consensus on the criteria to use for the selection, training and assessment of inspectors in order to ensure that different national or international programmes gain mutual recognition.

To evaluate the impact of a mobile phone short message on women's uptake in a breast cancer screening programme. A total of 703 women from a Basic Health Area of Barcelona, and with a mobile phone number registered, were invited to participate in a breast cancer screening programme between 25 January 2011 and 22 March 2011. The control group (n=470) followed the usual appointment track, and the intervention group (n=233) received, after the first letter of invitation, a mobile phone short message reminder. The differences between the two groups were analysed, comparing the uptake rates according to age, educational level, and participation in previous round, as well as the number of re-invitation calls to non-attenders according to uptake, age and level of education;and the percentages of exclusions of both groups. The intervention group had a greater uptake than the control group (78.1% vs. 72.3%), with a significant trend observed in the 55-59 years age group (P=.036) and the low secondary educational level (P=.014).The intervention group mean of re-invitation calls of non-attenders lower than the control group (.41 vs. .65, P<.05), a pattern observed in all the categories of the independent variables, and among younger age groups, lower and middle educational levels, and previously participating women (.09 vs. .19, P=.012). The inclusion of a mobile phone short message in a breast cancer screening programme may increase uptake rates and lead to a management improvement. Copyright © 2013 SECA.

To provide a physical exercise programme for older adults living in nursing homes. Pain is common among older persons and for those already in long-term care and having difficulty in coping with pain will be at risk of further reducing their optimal independent function. A quasi-experimental single group pretest-posttest design. Older persons from a nursing home were invited to join an eight-week physical exercise programme. Each session lasted an hour and sessions were conducted once a week by physiotherapist and nurses. Physical exercise programme consisted of stretching, strengthening, balancing, towel dancing and self-administered massage to various acupressure points. On completion of each session, older persons were given a pamphlet with pictures to illustrate the exercise of the day and they were encouraged to practise these exercises by themselves. Outcome measures including pain intensity, range of movement, activities of daily living and mobility were collected before and after the physical exercise programme. There were 75 older adult participants (57 female and 18 male, mean age 85.14 SD 5.30). Seventy-three percent (n = 55) of them had pain in the previous three months and were referred as pain group, while 25% (n = 20) were no pain group. Pain scores of 4.89 (on a 10-point scale) indicated medium pain intensity before the intervention for the pain group; the location of pain was mainly in the knee, back and shoulder. On completion of the physical exercise programme, there was a significant decrease in pain intensity to 2.89 (SD 2.14) (p < 0.01). There was a significant increase in range of movement in the neck, shoulder, back, hip and knee rotation, flex and abduction (p < 0.01). Mobility level was significantly increased post intervention, yet activities of daily living remained unchanged. The present study demonstrated the effectiveness of a physical exercise programme in relieving pain and enhancing functional mobility for older persons. Relevance to clinical practice.  It is important to educate older persons, especially those living in nursing homes, on the importance of engaging in regular physical exercise and maintaining mobility. © 2011 Blackwell Publishing Ltd.

Development of a mini-mobile digital radiography system by using wireless smart devices.

The current technologies that trend in digital radiology (DR) are toward systems using portable smart mobile as patient-centered care. We aimed to develop a mini-mobile DR system by using smart devices for wireless connection into medical information systems. We developed a mini-mobile DR system consisting of an X-ray source and a Complementary Metal-Oxide Semiconductor (CMOS) sensor based on a flat panel detector for small-field diagnostics in patients. It is used instead of the systems that are difficult to perform with a fixed traditional device. We also designed a method for embedded systems in the development of portable DR systems. The external interface used the fast and stable IEEE 802.11n wireless protocol, and we adapted the device for connections with Picture Archiving and Communication System (PACS) and smart devices. The smart device could display images on an external monitor other than the monitor in the DR system. The communication modules, main control board, and external interface supporting smart devices were implemented. Further, a smart viewer based on the external interface was developed to display image files on various smart devices. In addition, the advantage of operators is to reduce radiation dose when using remote smart devices. It is integrated with smart devices that can provide X-ray imaging services anywhere. With this technology, it can permit image observation on a smart device from a remote location by connecting to the external interface. We evaluated the response time of the mini-mobile DR system to compare to mobile PACS. The experimental results show that our system outperforms conventional mobile PACS in this regard.

Legitimisation, personalisation and maturation: Using the experiences of a compulsory mobile curriculum to reconceptualise mobile learning.

Smartphone use is well established in society, with increasing acceptance in many professional workplaces. Despite the growth in mobile resources, how students and teachers benefit from these devices remains under-researched. An exploration of student and educators views on the impact of mobile learning re-sources on placement learning experiences as part of the Leeds 'MBChB Mobile' programme. Focus groups incorporating visual methodologies were undertaken with students from each year group; semi-structured interviews were undertaken with clinical teaching staff, including those who experienced the mobile programme as students themselves. Four key themes emerged. 'Maturity of learning', related to the way in which senior students use resources in a more nuanced way than junior colleagues. 'Learning differently', identified 'personalisation' and 'just in time' opportunities that mobile resources afforded. 'Learning legitimately' was identified by students as key to ensuring they adopted appropriate behaviours in relation to mobile learning. Using mobile resources at undergraduate level was found to 'change learning patterns for life'. There is a need to further develop the educational theory behind using mobile resources for learning. The results here suggest that mobile technologies are shaping learning behaviours, and are an indicator of learning maturity, reflecting the wider context of societal enculturation.

Interventions to reduce the use of seclusion and restraint in inpatient psychiatric settings: what we know so far a review of the literature.

PubMed

Scanlan, Justin Newton

2010-07-01

In recent times, much attention has been focused on the reduction of seclusion and restraint in psychiatric settings. This paper analyzes evidence available from evaluations of single seclusion and/or restraint reduction programmes. A total of 29 papers were included in the review. Seven key strategy types emerged from the analysis: (i) policy change/leadership; (ii) external review/debriefing; (iii) data use; (iv) training; (v) consumer/family involvement; (vi) increase in staff ratio/crisis response teams; and (vii) programme elements/changes. Outcomes indicate that a range of reduction programmes are successful in reducing the frequency and duration of seclusion and restraint use, while at the same time maintaining a safe environment. The development of new seclusion and restraint reduction programmes should include strong leadership from local management; external seclusion and restraint review committees or post-incident debriefing and analysis; broad-based staff training and programme changes at a local level. Behavioural and cognitive-behavioural programmes appear to be very useful in child and adolescent services. Further systematic research should be conducted to more fully understand which elements of successful programmes are the most powerful in reducing incidents of seclusion and restraint.

The current selected features and profiles in a mobile device is usually set manually and do not use the external environment automatically to change it. The features and profile can be switching to silent mode in office, selecting a formal ringtone in office, describing the mood in the social network sites and a whole lot of similar things. These features and profiles of the mobile is usually related to facial expression of the person (happiness, sadness, disgust, anger, fear, and surprise), external appearance (different clothes in office and home) and surroundings of the person (office, home, park etc). The idea of the paper is to the use the above mentioned external events and changes the theme of the mobile phone. The change may be changing the color of mobile screen, select particular category of word suggestion during writing SMS, notes or document, select music playlist, call buddy with whom user would like to share stuff. Basically user will have a mobile that can understand user's emotion and do accordingly. The paper presents details about emotion reading and implementation using patter recognition technique to capture.

Promoting the quality and effectiveness of nursing education is an important factor, given the increased demand for nursing professionals. It is important to establish learning environments that provide personalised guidance and feedback to students about their practical skills and application of their theoretical knowledge. To explore and describe the knowledge and points of view of students and educators about introduction of new technologies into an undergraduate nursing programme. The qualitative design used Tesch's (1990) steps of descriptive data analysis to complete thematic analysis of the data collected in focus group discussions (FGDs) and individual interviews to identify themes. Themes identified from the students’ FGDs and individual interviews included: mobile devices as a communication tool; email, WhatsApp and Facebook as methods of communication; WhatsApp as a method of communication; nurses as role-models in the clinical setting; setting personal boundaries; and impact of mobile devices in clinical practice on professionalism. Themes identified from the FGD, individual interviews and a discussion session held with educators included: peer learning via mobile devices; email, WhatsApp and Facebook as methods of communication; the mobile device as a positive learning method; students need practical guidance; and ethical concerns in clinical facilities about Internet access and use of mobile devices. The research project established an understanding of the knowledge and points of view of students and educators regarding introduction of new technologies into an undergraduate nursing programme with the aim of enhancing integration of theory and clinical practice through use of mobile devices.

Black, Deborah A; O'Loughlin, Kate; Wilson, Leigh A

2018-06-01

Due to the impact of climate change, mobile applications (apps) providing information about the external environment have the potential to improve the health of older people. The purpose of this research was to undertake a scoping review of the evidence on the usability, feasibility and effectiveness of mobile apps to encourage access to activities outside the home in older people. A search of databases was undertaken with relevant keywords. Selected manuscripts were judged for relevance to the inclusion criteria and assessed for quality. Very few published studies examined mobile apps specifically designed to prevent, or to treat, chronic disease in ageing populations, and fewer had rigorous designs. No study addressed accessing the external environment in the context of climate change. This study demonstrates that there is a gap in the evidence about the mobile apps designed for healthy ageing and, more specifically, to improve access to the external environment. © 2018 AJA Inc.

Background Different smoking cessation programmes have been developed in the last decade but utilization by the elderly is low. We evaluated a pilot mobile smoking cessation service for the Chinese elderly in Hong Kong and identified predictors of quitting. Methods The Mobile Smoking Cessation Programme (MSCP) targeted elderly smokers (aged 60 or above) and provided service in a place that was convenient to the elderly. Trained counsellors provided individual counselling and 4 week's free supply of nicotine replacement therapy (NRT). Follow up was arranged at 1 month by face-to-face and at 3 and 6 months by telephone plus urinary cotinine validation. A structured record sheet was used for data collection. The service was evaluated in terms of process, outcome and cost. Results 102 governmental and non-governmental social service units and private residential homes for the elderly participated in the MSCP. We held 90 health talks with 3266 elderly (1140 smokers and 2126 non-smokers) attended. Of the 1140 smokers, 365 (32%) received intensive smoking cessation service. By intention-to-treat, the validated 7 day point prevalence quit rate was 20.3% (95% confidence interval: 16.2%–24.8%). Smoking less than 11 cigarettes per day and being adherent to NRT for 4 weeks or more were significant predictors of quitting. The average cost per contact was US$54 (smokers only); per smoker with counselling: US$168; per self-reported quitter: US$594; and per cotinine validated quitter: US$827. Conclusion This mobile smoking cessation programme was acceptable to elderly Chinese smokers, with quit rate comparable to other comprehensive programmes in the West. A mobile clinic is a promising model to reach the elderly and probably other hard to reach smokers. PMID:18837985

Physical therapists (PTs) display positive attitudes toward evidence-based practice (EBP), and implementing it can improve patient outcomes and reduce costs. However, barriers can lead to inconsistent use of EBP. The objectives of this manuscript are to (i) describe the initiation and revisions to a knowledge translation (KT) programme, (ii) assess staff participation in KT, and (iii) evaluate availability, internal use and external dissemination of evidence-based recommendations and research. The KT programme was implemented in a large paediatric hospital employing 66 PTs who provide services in the inpatient, outpatient developmental and sports and orthopaedics settings in 15 locations. The KT programme was initiated 9 years ago but underwent improvements over the past 3 years. Five key revisions included the subdivision of the EBP and Research Coordinator positions by area of practice, increasing the structure of the KT programme, implementing strategies to encourage use of local recommendations, obtaining leadership support to emphasize KT and providing staff education. With the revisions, staff participation in local recommendation development increased from 16.3-68.2%. Research involvement increased from 4.1-50%. The number of local recommendations increased from 1 to 9, and an overall compliance rate of 79% was achieved for the recommendations presented in an algorithm format. External dissemination increased from 1 to 44 for presentations and 0 to 7 for publications. Revisions to a KT programme improved PT engagement in KT activities, increased the availability of local recommendations, encouraged use of EBP and increased external dissemination of information. © 2016 John Wiley & Sons, Ltd.

Exercise programmes have important role in prevention of falls, but to date, we have little knowledge about the effects of Adapted Physical Activity programme on balance of older women. The aim of this study was to investigate the effects of an Adapted Physical Activity programme on balance, risk of falls and quality of life in community-dwelling older women. This was a randomized controlled study. Community, in a local sport centre. Older women aged over 60 years. Seventy-six women were randomised to an exercise group providing Adapted Physical Activity programme for 25 weeks or a control group (in which they did not participate in any exercise programme). The one-leg stance test, Timed Up and Go test, incidence of fall and the quality of life (SF-36V2) were measured at baseline and after 25 weeks. The one-leg stance test and the Timed Up and Go test in the exercise group was significantly better than in the control group after the intervention period (P=0.005; P=0.001, respectively). The Physical Functioning, Vitality and General Health subdomains of quality of life were also significantly better in the exercise group compared to the control group (P=0.004; P=0.005; P=0.038, respectively). Relative risk was 0.40 (90% CI 0.174 to 0.920) and the number needed to treat was 5 (95% CI 2.3 to 23.3). This 25-week Adapted Physical Activity programme improves static balance, functional mobility, as well as Physical Functioning, Vitality and General Health subdomains of quality of life. Based on our results, the Adapted Physical Activity programme may be a promising fall prevention exercise programme improving static balance and functional mobility for community-dwelling older women.

A pre-test/post-test design was used to investigate the influence of participation in the GCP on components of junior high-school students' environmental literacy. Conceptualizations of 'environment', environmental attitudes and sense of ability to act on environmental issues were studied employing quantitative and qualitative tools. Contribution of the programme to the cognitive domain, in developing a systemic understanding of the environment, was limited. On the other hand, participating in this programme heightened students' sensitivity to human-environment interrelationships and developed a more ecological worldview. After the programme, students demonstrated greater perception of humans as part of the environment, an increased sensitivity to human impact on the environment and their value for non-human nature moved from an anthropocentric to a more ecocentric orientation. While students' internal locus-of-control increased, when environmental protection entailed personal economic trade-offs, their support was limited and remained unchanged. The article concludes with recommendations, based on the findings, regarding supplementing the school (science) curriculum with external EE enrichment programmes.

Purpose: We explored patients' perspectives on home exercise programmes (HEPs) and their experiences using a mobile application designed to facilitate home exercise. Method: Data were generated using qualitative, semi-structured, face-to-face interviews with 10 participants who were receiving outpatient physiotherapy. Results: Establishing a therapeutic partnership between physiotherapists and patients enabled therapists to customize the HEPs to the patients' lifestyles and preferences. Analysis suggests that using the mobile application improved participants' ability to integrate the HEP into their daily life and was overwhelmingly preferred to traditional paper handouts. Conclusions: The results suggest that efforts to engage patients in HEPs need to take their daily lives into account. To move in this direction, sample exercise prescription questions are offered. Mobile applications do not replace the clinical encounter, but they can be an effective tool and an extension of delivering personalized HEPs in an existing therapeutic partnership.

With the explosive growth in UAV numbers forecast worldwide, a core concern is how to manage the ad-hoc network configuration required for mobility management. As UAVs migrate among ground control stations, associated network services, routing and operational control must also rapidly migrate to ensure a seamless transition. In this paper, we present a novel, lightweight and modular architecture which supports high mobility, resilience and flexibility through the application of SDN and NFV principles on top of the UAV infrastructure. By combining SDN programmability and Network Function Virtualization we can achieve resilient infrastructure migration of network services, such as network monitoring and anomaly detection, coupled with migrating UAVs to enable high mobility management. Our container-based monitoring and anomaly detection Network Functions (NFs) can be tuned to specific UAV models providing operators better insight during live, high-mobility deployments. We evaluate our architecture against telemetry from over 80flights from a scientific research UAV infrastructure.

We have shown theoretically that the electron mobility in wurtzite AlN/GaN/AlN heterostructures can be enhanced by compensating the built-in electric field with the externally applied perpendicular electric field and by introducing a shallow InxGa1-xN channel in the center of GaN potential well. It was found that two- to fivefold increase of the room temperature electron mobility can be achieved. The tuning of the electron mobility with the external electric field or InxGa1-xN channel can be useful for the design of GaN-based field-effect transistors and optoelectronic devices.

Young children exhibiting severe externalizing problems in school are at risk of developing several poor outcomes. School-based intervention programs have been found to be effective for students with different problems, including those with behavioral problems, emotional distress, or social problems. The present study investigated whether the IY-TCM programme, as a universal stand-alone school intervention programme, reduced severe child externalizing problems as reported by the teacher, and evaluated if these children improved their social competence, internalizing problems, academic performances and student- teacher relationship as a result of the IY TCM training. A quasi-experimental pre-post study was conducted, including 21 intervention schools and 22 control schools. Children in 1 st - 3 rd grade (age 6-8 years) assessed by their teacher as having severe externalizing problems on the Sutter-Eyberg Student Behavior Inventory-Revised (SESBI-R) total Intensity score, were included in the study, N = 83 (65 boys and 18 girls). Treatment effects were evaluated using 3- level linear mixed models analysis. In our study we found no differences in change between the two conditions from baseline to follow-up in externalizing problems, social skills, internalizing problems and closeness with teacher. The intervention condition did however show advantageous development in terms of student-teacher conflicts and increased academic performances. The IY Teacher Classroom Management program is not sufficient being a stand-alone universal program in a Norwegian primary school setting, for students with severe externalizing problems. However; some important secondary findings were found. Still, young school children with severe externalizing problems are in need of more comprehensive and tailored interventions.

This study aimed to analyse the effect of 12-week low-volume HIIT-based concurrent training programme on body composition, upper- and lower-body muscle strength, mobility and balance in older adults, as well as to compare it with a low- moderate-intensity continuous training. 90 active older adults were randomly assigned to experimental (EG, n=47), and control (CG, n=43) groups. Body composition and physical functioning were assessed before (pre-test) and after (post-test) a 12-week intervention. A 2-way repeated measures ANOVA was used to test for an interaction between training programme and groups. The time x group interaction revealed no significant between-group differences at pre-test (p≥0.05). The group x time interaction showed significant improvements for the EG in body composition parameters (p<0.05) and physical functioning (muscle strength: p<0.001; mobility: p<0.001; and balance: p<0.05); while the CG remained unchanged (p≥0.05). This HIIT-based concurrent training programme led to greater improvements in body composition, muscle strength, mobility and balance in healthy older people than a regular low- moderate-intensity continuous training, despite the reduction in overall training volume.

A reliable and reproducible report from a laboratory needs internal quality control within the laboratory and participation in external proficiency testing programmes (EPTP). This study conducted at the Department of Haematology, All India Institute of Medical Sciences (AIIMS), New Delhi, which has been conducting an EPTP since 1992, was undertaken to assess the efficacy of this programme in improving the performance of participating laboratories in reporting test samples sent for Hb, total leucocyte count (TLC), reticulocyte count and assessment of peripheral blood smear (PBS). The samples were prepared in our laboratory according to the International Standards Organization (ISO) guidelines. The performance of individual laboratories was assessed using robust Z score, which is an indicator of acceptability of the test result. An improvement in the overall percentage of laboratories with acceptable reports was seen during the study period. It has increased from 38,40,40 per cent in 1992 to 85, 90,94.7 per cent in 2006 for Hb, TLC, reticulocyte count, respectively. However, the results for peripheral smear assessment improved only marginally. The external haematology proficiency testing programme run by our department for Hb, TLC, reticulocyte count, and peripheral blood smear assessment, has helped in improving the reporting standards of these parameters in Indian laboratories.

Mental health care is now a major occupational health issue in Japan. Although realizing effective use of external employee assistance programmes (EAPs) has been identified as crucial for mental health care, few scientific papers describe or analyse the characteristics of EAPs in Japan. This study sought to clarify the characteristics of an external EAP in Japan. The characteristics of an external EAP were clarified in terms of programme description and utilization. A total of 10,260 counselling sessions from 1996 to 2000 were used for utilization analysis. The EAP studied had contracts with 133 organizations, half of which were health insurance societies. The EAP provided employees and family members with free, confidential counselling. Annual mean utilization rate per 1000 individuals increased from 1.3 in 1996 to 2.7 in 2000. Less than one-third of counselling sessions were for work-related mental health issues, and male users (30%) consulted significantly more often than female users (14%) for such problems. Among men, career development issues were most common, while job dissatisfaction was highest among women. Absenteeism, depression and fatigue were the most frequently observed problems in both sexes. EAP use in Japan is rising. The majority of its use is for non-work-related health issues. Male users were more likely to consult for work-related mental health problems.

Schistosomiasis remains a public health problem in many developing countries around the world. After the founding of The People's Republic of China, from 1949 till date, all levels of government, from central to local, have been attaching great importance to schistosomiasis control in The People's Republic of China. With considerable policy support and resources mobilization, the national schistosomiasis control programmes have been implemented during the past 65years. Here, we summarize the successful experience of schistosomiasis control during the process. Recommendations for the future management of the Chinese national schistosomiasis elimination programme are put forward after considering the remaining challenges, shortcomings and lessons learnt from 65years of schistosomiasis control drives in The People's Republic of China. They will help to sustain past achievements, foster the attainment of the ultimate goal of schistosomiasis elimination for the country and provide reference for schistosomiasis control programme in other countries.

This was an addition to the first, already running, programme for cervical cancer. Two of them are entrusted to the Institute of Oncology while the National CINDI programme takes care of the third one. Besides connection to some external public databases, cancer screening programmes require national Cancer Registry data. High quality and user friendly information support for citizens and medical professionals following doctrinal requirements and possible changes is a must.

Distributed finite-time trajectory tracking control for multiple nonholonomic mobile robots with uncertainties and external disturbances

Ou, Meiying; Sun, Haibin; Gu, Shengwei; Zhang, Yangyi

2017-11-01

This paper investigates the distributed finite-time trajectory tracking control for a group of nonholonomic mobile robots with time-varying unknown parameters and external disturbances. At first, the tracking error system is derived for each mobile robot with the aid of a global invertible transformation, which consists of two subsystems, one is a first-order subsystem and another is a second-order subsystem. Then, the two subsystems are studied respectively, and finite-time disturbance observers are proposed for each robot to estimate the external disturbances. Meanwhile, distributed finite-time tracking controllers are developed for each mobile robot such that all states of each robot can reach the desired value in finite time, where the desired reference value is assumed to be the trajectory of a virtual leader whose information is available to only a subset of the followers, and the followers are assumed to have only local interaction. The effectiveness of the theoretical results is finally illustrated by numerical simulations.

Malaria diagnosis has received renewed interest in recent years, associated with the increasing accessibility of accurate diagnosis through the introduction of rapid diagnostic tests and new World Health Organization guidelines recommending parasite-based diagnosis prior to anti-malarial therapy. However, light microscopy, established over 100 years ago and frequently considered the reference standard for clinical diagnosis, has been neglected in control programmes and in the malaria literature and evidence suggests field standards are commonly poor. Microscopy remains the most accessible method for parasite quantitation, for drug efficacy monitoring, and as a reference of assessing other diagnostic tools. This mismatch between quality and need highlights the importance of the establishment of reliable standards and procedures for assessing and assuring quality. This paper describes the development, function and impact of a multi-country microscopy external quality assurance network set up for this purpose in Asia. Surveys were used for key informants and past participants for feedback on the quality assurance programme. Competency scores for each country from 14 participating countries were compiled for analyses using paired sample t-tests. In-depth interviews were conducted with key informants including the programme facilitators and national level microscopists. External assessments and limited retraining through a formalized programme based on a reference slide bank has demonstrated an increase in standards of competence of senior microscopists over a relatively short period of time, at a potentially sustainable cost. The network involved in the programme now exceeds 14 countries in the Asia-Pacific, and the methods are extended to other regions. While the impact on national programmes varies, it has translated in some instances into a strengthening of national microscopy standards and offers a possibility both for supporting revival of national microcopy programmes, and for the development of globally recognized standards of competency needed both for patient management and field research.

There is extensive evidence that mobilization and manipulation of the thoracic spine is associated with improved outcomes in patients with neck pain. However, these evidence-based techniques are not always utilized. Successful knowledge translation programmes are needed to move the best available evidence to clinical practice. The purpose of the present research was to evaluate the effects of a structured knowledge translation programme on the frequency of manual therapy techniques performed by physical therapists on patients with neck pain. Prior to our intervention, we assessed physical therapists' use of thoracic spine intervention for the treatment of neck pain and their knowledge of the evidence. We delivered a multimodal knowledge translation programme and then reassessed their use and knowledge of the interventions. The majority of our physical therapists increased the use of thoracic spine techniques for their patients with neck pain. The increase was greater in those who used the techniques infrequently. Overall knowledge of the evidence appeared unchanged. Knowledge translation programmes are essential in ensuring clinical use of evidence-based practice. Our programme results, although on a small scale and not statistically significant, showed a positive trend toward increased thoracic spine manual therapy use for neck pain.

The future multi-modal user interfaces of battery-powered mobile devices are expected to require computationally costly image analysis techniques. The use of Graphic Processing Units for computing is very well suited for parallel processing and the addition of programmable stages and high precision arithmetic provide for opportunities to implement energy-efficient complete algorithms. At the moment the first mobile graphics accelerators with programmable pipelines are available, enabling the GPGPU implementation of several image processing algorithms. In this context, we consider a face tracking approach that uses efficient gray-scale invariant texture features and boosting. The solution is based on the Local Binary Pattern (LBP) features and makes use of the GPU on the pre-processing and feature extraction phase. We have implemented a series of image processing techniques in the shader language of OpenGL ES 2.0, compiled them for a mobile graphics processing unit and performed tests on a mobile application processor platform (OMAP3530). In our contribution, we describe the challenges of designing on a mobile platform, present the performance achieved and provide measurement results for the actual power consumption in comparison to using the CPU (ARM) on the same platform.

Towards the development of tamper-resistant, ground-based mobile sensor nodes

NASA Astrophysics Data System (ADS)

Mascarenas, David; Stull, Christopher; Farrar, Charles

2011-11-01

Mobile sensor nodes hold great potential for collecting field data using fewer resources than human operators would require and potentially requiring fewer sensors than a fixed-position sensor array. It would be very beneficial to allow these mobile sensor nodes to operate unattended with a minimum of human intervention. In order to allow mobile sensor nodes to operate unattended in a field environment, it is imperative that they be capable of identifying and responding to external agents that may attempt to tamper with, damage or steal the mobile sensor nodes, while still performing their data collection mission. Potentially hostile external agents could include animals, other mobile sensor nodes, or humans. This work will focus on developing control policies to help enable a mobile sensor node to identify and avoid capture by a hostile un-mounted human. The work is developed in a simulation environment, and demonstrated using a non-holonomic, ground-based mobile sensor node. This work will be a preliminary step toward ensuring the cyber-physical security of ground-based mobile sensor nodes that operate unattended in potentially unfriendly environments.

Although community case management of malaria increases access to life-saving care in isolated settings, it contends with many logistical challenges. Mobile phone health information technology may present an opportunity to address a number of these barriers. Using the wireless adaptation of the technology acceptance model, this study assessed availability, ease of use, usefulness, and job relevance of mobile phones by health workers in Saraya, Senegal. This study conducted seven key informant interviews with government health workers, and three focus groups and 76 surveys with lay health workers. Principal findings included that mobile phones are already widely available and used, and that participants valued using phones to address training, stock management, programme reporting, and transportation challenges. By documenting widespread use of mobile phones and health worker perceptions of their most useful applications, this paper provides a framework for their integration into the community case management of malaria programme in Saraya, Senegal. © The Author 2014.

Behavioural parent training is effective in improving child disruptive behavioural problems in preschool children by increasing parenting competence. The indicated Prevention Programme for Externalizing Problem behaviour (PEP) is a group training programme for parents and kindergarten teachers of children aged 3-6 years with externalizing behavioural problems. To evaluate the effects of PEP on child problem behaviour, parenting practices, parent-child interactions, and parental quality of life. Parents and kindergarten teachers of 155 children were randomly assigned to an intervention group (n = 91) and a nontreated control group (n = 64). They rated children's problem behaviour before and after PEP training; parents also reported on their parenting practices and quality of life. Standardized play situations were video-taped and rated for parent-child interactions, e.g. parental warmth. In the intention to treat analysis, mothers of the intervention group described less disruptive child behaviour and better parenting strategies, and showed more parental warmth during a standardized parent-child interaction. Dosage analyses confirmed these results for parents who attended at least five training sessions. Children were also rated to show less behaviour problems by their kindergarten teachers. Training effects were especially positive for parents who attended at least half of the training sessions.

We conducted a systematic review of the literature on the use of mobile phones for weight loss. A total of 43 studies were identified on obese or overweight adults, aged 18 years or over. After review, ten articles met the inclusion criteria. There were 19-534 participants per study. Participants were from European, Asian and North American regions. The mean body mass index (BMI) of the subjects varied from 22 to 36 kg/m(2). Two studies used text messaging or multimedia messaging. All the other studies used mobile-phone apps or web-based programmes that could be accessed from mobile phones as a part of a weight-loss intervention or for evaluating their potential for use and their acceptance. Most studies lasted 2-4 months and the maximum duration was 1 year. All but two studies showed reductions in the participants' bodyweight, BMI, waist circumference and body fat in the various interventions. There appeared to be a proportional relationship between weight loss and programme use. The programmes most benefited those who took a pro-active approach to everyday problems. Frequent self-recording of weight seemed to be important, as was the personalisation of the intervention (counselling and individualized feedback). Finally, a social support system acted as a motivational tool. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

The sustainability of successful public health programmes remains a challenge in low and middle income settings. These programmes are often subjected to mobilization-demobilization cycle. Indeed, political and organizational factors are of major importance to ensure this sustainability. The cooperation between the World Bank and the Brazilian AIDS programme highlights the role of international institutions and global health initiatives (GHI), not only to scale up programmes but also to guarantee their stability and sustainability, at a time when advocacy is diminishing and vertical programmes are integrated within health systems. This role is critical at the local level, particularly when economic crisis may hamper the future of public health programmes. Political and organizational evolution should be monitored and warnings should trigger interventions of GHI before the decline of these programmes.

Some studies suggest that a workplace prevention programme could reduce health inequalities related to education level and improve the health status of the employees. The objective of the study was to demonstrate the advantages for a company to implement a health prevention programme in the workplace in order to: 1-improve health literacy 2 - change health-related behaviours 3-improve the company image. A "before - after" methodology was used in a population of 2153 employees of three companies. Three areas of prevention were considered: nutrition, physical activity and prevention of back pain. The successive steps of the EBS programme included general communication, group workshops and individual coaching. Data collection was carried out using anonymous questionnaires sent by e-mail. A global assessment was performed based on the companies' pooled data, with separate analysis according to the steps of the programme. The programme mobilized employees with participation rates ranging from 25% to 45.5%. After completion of the full programme, 77.5% of respondents reported an improvement of their health knowledge versus 50.3% of those who only received general communication. Behavioural modification was observed, especially in the fields of nutrition and back pain.. EBS can be considered to be a vector of the company image for almost 7 out of 10 employees. A health prevention education programme provided by the company in the workplace mobilizes employees and contributes to improvement of health knowledge and behaviour change. All approaches tested were important and applicable to various types of companies or workers.

A system and method for acquisition management of subject position information that utilizes radio frequency identification (RF ID) to store position information in position tags. Tag programmers receive position information from external positioning systems, such as the Global Positioning System (GPS), from manual inputs, such as keypads, or other tag programmers. The tag programmers program each position tag with the received position information. Both the tag programmers and the position tags can be portable or fixed. Implementations include portable tag programmers and fixed position tags for subject position guidance, and portable tag programmers for collection sample labeling. Other implementations include fixed tag programmers and portable position tags for subject route recordation. Position tags can contain other associated information such as destination address of an affixed subject for subject routing.

The predicted demographic changes internationally have implications for the nature of care that older people receive and place of care as they age. Healthcare policy now promotes the implementation of end-of-life care interventions to improve care delivery within different settings. The Gold Standards Framework in Care Homes (GSFCH) programme is one end-of-life care initiative recommended by the English Department of Health. Only a small number of care homes that start the programme complete it, which raises questions about the implementation process. To identify the type, role, impact and cost of facilitation when implementing the GSFCH programme into nursing care home practice. A mixed-methods study. Nursing care homes in south-east England. Staff from 38 nursing care homes undertaking the GSFCH programme. Staff in 24 nursing care homes received high facilitation. Of those, 12 also received action learning. The remaining 14 nursing care homes received usual local facilitation of the GSFCH programme. Study data were collected from staff employed within nursing care homes (home managers and GSFCH coordinators) and external facilitators associated with the homes. Data collection included interviews, surveys and facilitator activity logs. Following separate quantitative (descriptive statistics) and qualitative (template) data analysis the data sets were integrated by 'following a thread'. This paper reports study data in relation to facilitation. Three facilitation approaches were provided to nursing home staff when implementing the GSFCH programme: 'fitting it in' facilitation; 'as requested' facilitation; and 'being present' facilitation. 'Being present' facilitation most effectively enabled the completion of the programme, through to accreditation. However, it was not sufficient to just be present. Without mastery and commitment, from all participants, including the external facilitator, learning and initiation of change failed to occur. Implementation of the programme required an external facilitator who could mediate multi-layered learning at an individual, organisational and appreciative system level. The cost savings in the study outweighed the cost of providing a 'being present' approach to facilitation. Different types of facilitation are offered to support the implementation of end-of-life care initiatives. However, in this study 'being present' facilitation, when supported by multi-layered learning, was the only approach that initiated the change required. Copyright © 2018. Published by Elsevier Ltd.

Surveillance and response for high-risk populations: what can malaria elimination programmes learn from the experience of HIV?

PubMed

Jacobson, Jerry O; Cueto, Carmen; Smith, Jennifer L; Hwang, Jimee; Gosling, Roly; Bennett, Adam

2017-01-18

To eliminate malaria, malaria programmes need to develop new strategies for surveillance and response appropriate for the changing epidemiology that accompanies transmission decline, in which transmission is increasingly driven by population subgroups whose behaviours place them at increased exposure. Conventional tools of malaria surveillance and response are likely not sufficient in many elimination settings for accessing high-risk population subgroups, such as mobile and migrant populations (MMPs), given their greater likelihood of asymptomatic infections, illegal risk behaviours, limited access to public health facilities, and high mobility including extended periods travelling away from home. More adaptive, targeted strategies are needed to monitor transmission and intervention coverage effectively in these groups. Much can be learned from HIV programmes' experience with "second generation surveillance", including how to rapidly adapt surveillance and response strategies to changing transmission patterns, biological and behavioural surveys that utilize targeted sampling methods for specific behavioural subgroups, and methods for population size estimation. This paper reviews the strategies employed effectively for HIV programmes and offers considerations and recommendations for adapting them to the malaria elimination context.

2012-04-01

INVOGE is an EU-US bilateral cooperation programme funded by the EACEA (EU) and FIPSE (US). The partner universities are Blaise Pascal ( UBP, Clermont-Ferrand, France), University of Milan-Bicocca (Italy), Michigan Technological University (US) and the University at Buffalo (US). Students spend one academic year on the opposing side of the Atlantic and a shorter time on mobility at the secondary European partner. The project is a partial merger of four masters programmes that have similar fields of study, but widely differing speciality courses and great cultural and linguistic differences. The partner universities also have major implantations in developing nations, in Latin America and South East Asia, areas from which are drawn a both students and staff. In this presentation we show how we are creating a sustainable structure to train internationally mobile, multilingual geoscientists in both developed and developing nations both within the present INVOGE master and in associated programmes. For example at UBP the newly created CLERVOLC 'laboratoire d'excelence' programme associates research in several domains with the international outreach associated with the Institute for Research and Development (IRD) into the international Masters programme, seamlessly coupling research and education into projects such as INVOGE. The other partner universities are developing similar internconnected international projects. We also will detail the problems related to moving students from widely different backgrounds around culturally and linguistically diverse universities and will discuss how we are tackling such problems, with internet-based courses, language and cultural training for students and staff training, curriculum changes, close student - staff integration into project development and the creation of alumni organisations.

2012-07-01

We present a cost-effective portable ultrasound system based on a single field-programmable gate array (FPGA) for point-of-care applications. In the portable ultrasound system developed, all the ultrasound signal and image processing modules, including an effective 32-channel receive beamformer with pseudo-dynamic focusing, are embedded in an FPGA chip. For overall system control, a mobile processor running Linux at 667 MHz is used. The scan-converted ultrasound image data from the FPGA are directly transferred to the system controller via external direct memory access without a video processing unit. The potable ultrasound system developed can provide real-time B-mode imaging with a maximum frame rate of 30, and it has a battery life of approximately 1.5 h. These results indicate that the single FPGA-based portable ultrasound system developed is able to meet the processing requirements in medical ultrasound imaging while providing improved flexibility for adapting to emerging POC applications.

The present article describes the development of a peripheral interface controller (PIC) microcontroller-based system for interfacing external add-on peripherals with a real mobile robot, for real life applications. This system serves as an important building block of a complete integrated vision-based mobile robot system, integrated indigenously in our laboratory. The system is composed of the KOALA mobile robot in conjunction with a personal computer (PC) and a two-camera-based vision system where the PIC microcontroller is used to drive servo motors, in interrupt-driven mode, to control additional degrees of freedom of the vision system. The performance of the developed system is tested by checking it under the control of several user-specified commands, issued from the PC end.

Causes and consequences of psychological distress among orphans in eastern Zimbabwe

Substantial resources are invested in psychological support for children orphaned or otherwise made vulnerable in the context of HIV/AIDS (OVC). However, there is still only limited scientific evidence for greater psychological distress amongst orphans and even less evidence for the effectiveness of current support strategies. Furthermore, programmes that address established mechanisms through which orphanhood can lead to greater psychological distress should be more effective. We use quantitative and qualitative data from Eastern Zimbabwe to measure the effects of orphanhood on psychological distress and to test mechanisms for greater distress amongst orphans suggested in a recently published theoretical framework. Orphans were found to suffer greater psychological distress than non-orphans (sex- and age-adjusted co-efficient: 0.15; 95% CI 0.03–0.26; P = 0.013). Effects of orphanhood contributing to their increased levels of distress included trauma, being out-of-school, being cared for by a non-parent, inadequate care, child labour, physical abuse, and stigma and discrimination. Increased mobility and separation from siblings did not contribute to greater psychological distress in this study. Over 40% of orphaned children in the sample lived in households receiving external assistance. However, receipt of assistance was not associated with reduced psychological distress. These findings and the ideas put forward by children and caregivers in the focus group discussions suggest that community-based programmes that aim to improve caregiver selection, increase support for caregivers, and provide training in parenting responsibilities and skills might help to reduce psychological distress. These programmes should be under-pinned by further efforts to reduce poverty, increase school attendance and support out-of-school youth. PMID:20552465

Self-shaping composites with programmable bioinspired microstructures.

Erb, Randall M; Sander, Jonathan S; Grisch, Roman; Studart, André R

2013-01-01

Shape change is a prevalent function apparent in a diverse set of natural structures, including seed dispersal units, climbing plants and carnivorous plants. Many of these natural materials change shape by using cellulose microfibrils at specific orientations to anisotropically restrict the swelling/shrinkage of their organic matrices upon external stimuli. This is in contrast to the material-specific mechanisms found in synthetic shape-memory systems. Here we propose a robust and universal method to replicate this unusual shape-changing mechanism of natural systems in artificial bioinspired composites. The technique is based upon the remote control of the orientation of reinforcing inorganic particles within the composite using a weak external magnetic field. Combining this reinforcement orientational control with swellable/shrinkable polymer matrices enables the creation of composites whose shape change can be programmed into the material's microstructure rather than externally imposed. Such bioinspired approach can generate composites with unusual reversibility, twisting effects and site-specific programmable shape changes.

Two structured doctoral programmes that we have in Hannover, the IMPRS on Gravitational Wave Astronomy and SFB on relativistic geodesy and gravimetry with quantum sensors geo-Q, have not only become major resources for education in each field but have also started to provide substantial synergy to members of both programmes. Our strong crossdisciplinary approach to create a joint programme has received excellent feedback not only from researchers inside the programme but also from various external committee. Building on experience that we have acquired over the last decade, we propose to set up a common doctoral programme within the international gravitational wave astronomy and physics. We envisage that with a common doctoral programme we will create a strong team of young researchers who will carry on building a strong network of third generation gravitational wave detectors and observatories.

Addressing the social determinants of health: a case study from the Mitanin (community health worker) programme in India

PubMed Central

Schneider, Helen

2014-01-01

The Mitanin Programme, a government community health worker (CHW) programme, was started in Chhattisgarh State of India in 2002. The CHWs (Mitanins) have consistently adopted roles that go beyond health programme-specific interventions to embrace community mobilization and action on local priorities. The aim of this research was to document how and why the Mitanins have been able to act on the social determinants of health, describing the catalysts and processes involved and the enabling programmatic and organizational factors. A qualitative comparative case study of successful action by Mitanin was conducted in two ‘blocks’, purposefully selected as positive exemplars in two districts of Chhattisgarh. One case focused on malnutrition and the other on gender-based violence. Data collection involved 17 in-depth interviews and 10 group interviews with the full range of stakeholders in both blocks, including community members and programme team. Thematic analysis was done using a broad conceptual framework that was further refined. Action on social determinants involved raising awareness on rights, mobilizing women’s collectives, revitalizing local political structures and social action targeting both the community and government service providers. Through these processes, the Mitanins developed identities as agents of change and advocates for the community, both with respect to local cultural and gender norms and in ensuring accountability of service providers. The factors underpinning successful action on social determinants were identified as the significance of the original intent and vision of the programme, and how this was carried through into all aspects of programme design, the role of the Mitanins and their identification with village women, ongoing training and support, and the relative autonomy of the programme. Although the results are not narrowly generalizable and do not necessarily represent the situation of the Mitanin Programme as a whole, the explanatory framework may provide general lessons for programmes in similar contexts.

2014-01-01

In 2010, the Zimbabwe Ministry of Health and Child Welfare (MoHCW) adopted the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme as a tool for laboratory quality systems strengthening. To evaluate the financial costs of SLMTA implementation using two models (external facilitators; and internal local or MoHCW facilitators) from the perspective of the implementing partner and to estimate resources needed to scale up the programme nationally in all 10 provinces. The average expenditure per laboratory was calculated based on accounting records; calculations included implementing partner expenses but excluded in-kind contributions and salaries of local facilitators and trainees. We also estimated theoretical financial costs, keeping all contextual variables constant across the two models. Resource needs for future national expansion were estimated based on a two-phase implementation plan, in which 12 laboratories in each of five provinces would implement SLMTA per phase; for the internal facilitator model, 20 facilitators would be trained at the beginning of each phase. The average expenditure to implement SLMTA in 11 laboratories using external facilitators was approximately US$5800 per laboratory; expenditure in 19 laboratories using internal facilitators was approximately $6000 per laboratory. The theoretical financial cost of implementing a 12-laboratory SLMTA cohort keeping all contextual variables constant would be approximately $58 000 using external facilitators; or $15 000 using internal facilitators, plus $86 000 to train 20 facilitators. The financial cost for subsequent SLMTA cohorts using the previously-trained internal facilitators would be approximately $15 000, yielding a break-even point of 2 cohorts, at $116 000 for either model. Estimated resources required for national implementation in 120 laboratories would therefore be $580 000 using external facilitators ($58 000 per province) and $322 000 using internal facilitators ($86 000 for facilitator training in each of two phases plus $15 000 for SLMTA implementation in each province). Investing in training of internal facilitators will result in substantial savings over the scale-up of the programme. Our study provides information to assist policy makers to develop strategic plans for investing in laboratory strengthening.

2015-05-01

The aim of this research was to inform the development of mobile phone-assisted health promotion programmes that support social connectedness among refuge women to enhance their mental, physical and social health. For refugees, relationship development during the early stages of resettlement is often difficult. Enhancing personal skills, and resources, can enhance relationships that provide social support. It can also contribute to the development of social relationships in communities and thence acculturation. Communication technologies can assist refugees, if their particular needs and capacities are taken into account. This paper reports a study of refugee women's experience of an intervention based on principles of empowerment and using peer support training and the provision of free mobile phones, and free calls, for at least 1 year. Potential participants were invited by the Afghan, Burmese and Sudanese community leaders to an information session, where the study was explained and invitations to participate extended. A snowball sampling technique was also used, where the first group of participants invited people they had relationships with to join the programme. One hundred and eleven participants were recruited from the three groups. All were from refugee backgrounds. Data collection consisted of: a pre- and post-intervention questionnaire; a log of outgoing phone calls; and in-depth interviews with a subgroup of the study population. The call logs described the patterns of interpersonal relationships facilitated by the mobile phones. In the interviews, characteristics of interpersonal social support, and relationships with heritage and host communities, were described. The quantitative data were analysed using descriptive statistics and the qualitative data using thematic analysis. By describing the conditions under which mobile phone technology can enhance interpersonal and community connectedness, we strengthen the evidence base for the use of mobile phone technology in health promotion programmes with refugee groups. © 2014 John Wiley & Sons Ltd.

2013-02-01

Although Botswana has recently been categorised as an upper middle income country, it is burdened by a scarcity of resources, both human and technological. There are barriers to patients' access to specialized care and healthcare providers' access to medical knowledge. Over the past three years, the Botswana-University of Pennsylvania Partnership (BUP) has piloted four mobile telemedicine projects in the specialties of women's health (cervical cancer screening utilizing visual inspection with acetic acid), radiology, oral medicine and dermatology. Mobile telemedicine has been used in 11 locations in Botswana, training a total of 24 clinicians and successfully contributing to the management of 643 cases. In addition to mobile telemedicine, BUP has initiated an m-learning programme with the University of Botswana School of Medicine. While successfully providing patients and providers with improved access to healthcare resources, the m-health projects have faced numerous technical and social challenges. These include malfunctioning mobile devices, unreliable IT infrastructure, accidental damage to mobile devices, and cultural misalignment between IT and healthcare providers. BUP has worked with its local partners to develop solutions to these problems. To ensure sustainability, m-health programmes must have strategic goals that are aligned with those of the national health and education system, and the initiatives must be owned and led by local stakeholders. Whenever possible, open source technology and local IT expertise and infrastructure should be employed.

Dasari, Venkat R.; Sadlier, Ronald J.; Prout, Ryan; Williams, Brian P.; Humble, Travis S.

2016-05-01

Software-defined networking offers a device-agnostic programmable framework to encode new network functions. Externally centralized control plane intelligence allows programmers to write network applications and to build functional network designs. OpenFlow is a key protocol widely adopted to build programmable networks because of its programmability, flexibility and ability to interconnect heterogeneous network devices. We simulate the functional topology of a multi-node quantum network that uses programmable network principles to manage quantum metadata for protocols such as teleportation, superdense coding, and quantum key distribution. We first show how the OpenFlow protocol can manage the quantum metadata needed to control the quantum channel. We then use numerical simulation to demonstrate robust programmability of a quantum switch via the OpenFlow network controller while executing an application of superdense coding. We describe the software framework implemented to carry out these simulations and we discuss near-term efforts to realize these applications.

General and Direct Method for Preparing Oligonucleotide-Functionalized Metal-Organic Framework Nanoparticles.

Metal-organic frameworks (MOFs) are a class of modular, crystalline, and porous materials that hold promise for storage and transport of chemical cargoes. Though MOFs have been studied in bulk forms, ways of deliberately manipulating the external surface functionality of MOF nanoparticles are less developed. A generalizable approach to modify their surfaces would allow one to impart chemical functionality onto the particle surface that is independent of the bulk MOF structure. Moreover, the use of a chemically programmable ligand, such as DNA, would allow for the manipulation of interparticle interactions. Herein, we report a coordination chemistry-based strategy for the surface functionalization of the external metal nodes of MOF nanoparticles with terminal phosphate-modified oligonucleotides. The external surfaces of nine distinct archetypical MOF particles containing four different metal species (Zr, Cr, Fe, and Al) were successfully functionalized with oligonucleotides, illustrating the generality of this strategy. By taking advantage of the programmable and specific interactions of DNA, 11 distinct MOF particle-inorganic particle core-satellite clusters were synthesized. In these hybrid nanoclusters, the relative stoichiometry, size, shape, and composition of the building blocks can all be independently controlled. This work provides access to a new set of nucleic acid-nanoparticle conjugates, which may be useful as programmable material building blocks and as probes for measuring and manipulating intracellular processes.

2016-01-01

This study explores the opinions of primary school teachers about health activities carried out in schools in Alicante city (Spain). An exploratory study was conducted through qualitative content analysis. Three focus groups were conducted with 25 primary school teachers (14 women and 11 men) working in 14 public and 7 private schools in the city of Alicante. Participants were asked about the health activities carried on in their schools. Teachers distinguished between health education activities promoted by the school and those included in external programmes promoted by public and private institutions. External programmes were considered as impositions, lacking continuity and chosen according to passing fads. Although teachers demonstrated a more positive attitude towards activities arising from their own initiative, they identified health education as a secondary task. Teachers considered that improving their own health education training and promoting the involvement of parents, health professionals and public institutions were the most appropriate ways to promote health education in the school. Teachers showed a more positive opinion and greater commitment towards health activities that complement and facilitate their teaching tasks. Their didactic programme and opinion should be taken into account to maximise the efficiency of the health promotion and education activities promoted by external organisations.

India has few mental health professionals to treat the large number of people suffering from mental disorders. Rural areas are particularly disadvantaged due to lack of trained health workers. Ways to improve care could be by training village health workers in basic mental health care, and by using innovative methods of service delivery. The ongoing Systematic Medical Appraisal, Referral and Treatment Mental Health Programme will assess the acceptability, feasibility and preliminary effectiveness of a task-shifting mobile-based intervention using mixed methods, in rural Andhra Pradesh, India. The key components of the study are an anti-stigma campaign followed by a mobile-based mental health services intervention. The study will be done across two sites in rural areas, with intervention periods of 1 year and 3 months, respectively. The programme uses a mobile-based clinical decision support tool to be used by non-physician health workers and primary care physicians to screen, diagnose and manage individuals suffering from depression, suicidal risk and emotional stress. The key aim of the study will be to assess any changes in mental health services use among those screened positive following the intervention. A number of other outcomes will also be assessed using mixed methods, specifically focussed on reduction of stigma, increase in mental health awareness and other process indicators. This project addresses a number of objectives as outlined in the Mental Health Action Plan of World Health Organization and India's National Mental Health Programme and Policy. If successful, the next phase will involve design and conduct of a cluster randomised controlled trial.

In Mozambique, integrated community case management (iCCM) of diarrhoea, malaria and pneumonia is embedded in the national community health worker (CHW) programme, mainstreaming it into government policy and service delivery. Since its inception in 1978, the CHW programme has functioned unevenly, was suspended in 1989, but relaunched in 2010. To assess the long-term success of iCCM in Mozambique, this article addresses whether the current CHW programme exhibits characteristics that facilitate or impede its sustainability. We undertook a qualitative case study based on document review (n = 54) and key informant interviews (n = 21) with respondents from the Ministry of Health (MOH), multilateral and bilateral agencies and non-governmental organizations (NGOs) in Maputo in 2012. Interviews were mostly undertaken in Portuguese and all were coded using NVivo. A sustainability framework guided thematic analysis according to nine domains: strategic planning, organizational capacity, programme adaptation, programme monitoring and evaluation, communications, funding stability, political support, partnerships and public health impact. Government commitment was high, with the MOH leading a consultative process in Maputo and facilitating successful technical coordination. The MOH made strategic decisions to pay CHWs, authorize their prescribing abilities, foster guidance development, support operational planning and incorporate previously excluded 'old' CHWs. Nonetheless, policy negotiations excluded certain key actors and uncertainty remains about CHW integration into the civil service and their long-term retention. In addition, reliance on NGOs and donor funding has led to geographic distortions in scaling up, alongside challenges in harmonization. Finally, dependence on external funding, when both external and government funding are declining, may hamper sustainability. Our analysis represents a nuanced assessment of the various domains that influence CHW programme sustainability, highlighting strategic areas such as CHW payment and programme financing. These organizational and contextual determinants of sustainability are central to CHW programme strengthening and iCCM policy support. © The Author 2015.

Fundamental and future prospects of printed ambipolar fluorene-type polymer light-emitting transistors for improved external quantum efficiency, mobility, and emission pattern

Kajii, Hirotake

2018-05-01

In this review, we focus on the improved external quantum efficiency, field-effect mobility, and emission pattern of top-gate-type polymer light-emitting transistors (PLETs) based on ambipolar fluorene-type polymers. A low-temperature, high-efficiency, printable red phosphorescent PLET based on poly(alkylfluorene) with modified alkyl side chains fabricated by a film transfer process is demonstrated. Device fabrication based on oriented films leads to an improved EL intensity owing to the increase in field-effect mobility. There are three factors that affect the transport of carriers, i.e., the energy level, threshold voltage, and mobility of each layer for heterostructure PLETs, which result in various emission patterns such as the line-shaped, multicolor and in-plane emission pattern in the full-channel area between source and drain electrodes. Fundamentals and future prospects in heterostructure devices are discussed and reviewed.

Rheumatic heart disease (RHD) remains a major disease burden in low-resource settings globally. Patient registers have long been recognised to be an essential instrument in RHD control and elimination programmes, yet to date rely heavily on paper-based data collection and non-networked data-management systems, which limit their functionality. To assess the feasibility and potential benefits of producing an electronic RHD patient register. We developed an eRegister based on the World Heart Federation's framework for RHD patient registers using CommCare, an open-source, cloud-based software for health programmes that supports the development of customised data capture using mobile devices. The resulting eRegistry application allows for simultaneous data collection and entry by field workers using mobile devices, and by providers using computer terminals in clinics and hospitals. Data are extracted from CommCare and are securely uploaded into a cloud-based database that matches the criteria established by the WHF framework. The application can easily be tailored to local needs by modifying existing variables or adding new ones. Compared with traditional paper-based data-collection systems, the eRegister reduces the risk of data error, synchronises in real-time, improves clinical operations and supports management of field team operations. The user-friendly eRegister is a low-cost, mobile, compatible platform for RHD treatment and prevention programmes based on materials sanctioned by the World Heart Federation. Readily adaptable to local needs, this paperless RHD patient register program presents many practical benefits.

Hierarchical rank and women's organizational mobility: glass ceilings in corporate law firms.

PubMed

Gorman, Elizabeth H; Kmec, Julie A

2009-03-01

This article revives the debate over whether women's upward mobility prospects decline as they climb organizational hierarchies. Although this proposition is a core element of the "glass ceiling" metaphor, it has failed to gain strong support in previous research. The article establishes a firm theoretical foundation for expecting an increasing female disadvantage, with an eye toward defining the scope conditions and extending the model to upper-level external hires. The approach is illustrated in an empirical setting that meets the proposed scope conditions: corporate law firms in the United States. Results confirm that in this setting, the female mobility disadvantage is greater at higher organizational levels in the case of internal promotions, but not in the case of external hires.

A two-way coherent inductive communications link between an external transceiver and an internal transceiver located in a biologically implanted programmable medical device. Digitally formatted command data and programming data is transmitted to the implanted medical device by frequency shift keying the inductive communications link. Internal transceiver is powered by the inductive field between internal and external transceivers. Digitally formatted data is transmitted to external transceiver by internal transceiver amplitude modulating inductive field. Immediate verification of the establishment of a reliable communications link is provided by determining existence of frequency lock and bit phase lock between internal and external transceivers.

Many channel arbitrary pulse sequence generation is required for the electro-optic reconfiguration of optical waveguide networks in Lithium Niobate. Here we describe a scalable solution to the requirement for mid-power bipolar parallel outputs, based on pulse patterns generated by an externally clocked field programmable gate array. Positive and negative pulses can be generated at repetition rates up to 80 MHz with pulse width adjustable in increments of 1.6 ns across nine independent outputs. Each channel can provide 1.5 W of RF power and can be synchronised with the operation of other components in an optical network such as light sourcesmore » and detectors through an external clock with adjustable delay.« less

Electrophoretic mobilities of counterions and a polymer in cylindrical pores

PubMed Central

Singh, Sunil P.; Muthukumar, M.

2014-01-01

We have simulated the transport properties of a uniformly charged flexible polymer chain and its counterions confined inside cylindrical nanopores under an external electric field. The hydrodynamic interaction is treated by describing the solvent molecules explicitly with the multiparticle collision dynamics method. The chain consisting of charged monomers and the counterions interact electrostatically with themselves and with the external electric field. We find rich behavior of the counterions around the polymer under confinement in the presence of the external electric field. The mobility of the counterions is heterogeneous depending on their location relative to the polymer. The adsorption isotherm of the counterions on the polymer depends nonlinearly on the electric field. As a result, the effective charge of the polymer exhibits a sigmoidal dependence on the electric field. This in turn leads to a nascent nonlinearity in the chain stretching and electrophoretic mobility of the polymer in terms of their dependence on the electric field. The product of the electric field and the effective polymer charge is found to be the key variable to unify our simulation data for various polymer lengths. Chain extension and the electrophoretic mobility show sigmoidal dependence on the electric field, with crossovers from the linear response regime to the nonlinear regime and then to the saturation regime. The mobility of adsorbed counterions is nonmonotonic with the electric field. For weaker and moderate fields, the adsorbed counterions move with the polymer and at higher fields they move opposite to the polymer's direction. We find that the effective charge and the mobility of the polymer decrease with a decrease in the pore radius. PMID:25240366

Effects of an exercise programme for chronically ill and mobility-restricted elderly with structured support by the general practitioner's practice (HOMEfit) - study protocol of a randomised controlled trial

PubMed Central

2011-01-01

Background Exercise programmes can be administered successfully as therapeutic agents to patients with a number of chronic diseases and help to improve physical functioning in older adults. Usually, such programmes target either healthy and mobile community-dwelling seniors or elderly individuals living in nursing institutions or special residences. Chronically ill or mobility-restricted individuals, however, are difficult to reach when they live in their own homes. A pilot study has shown good feasibility of a home-based exercise programme that is delivered to this target group through cooperation between general practitioners and exercise therapists. A logical next step involves evaluation of the effects of the programme. Methods/design The study is designed as a randomised controlled trial. We plan to recruit 210 patients (≥ 70 years) in about 15 general practices. The experimental intervention (duration 12 weeks)-a multidimensional home-based exercise programme-is delivered to the participant by an exercise therapist in counselling sessions at the general practitioner's practice and on the telephone. It is based on methods and strategies for facilitating behaviour change according to the Health Action Process Approach (HAPA). The control intervention-baseline physical activities-differs from the experimental intervention with regard to content of the counselling sessions as well as to content and frequency of the promoted activities. Primary outcome is functional lower body strength measured by the "chair-rise" test. Secondary outcomes are: physical function (battery of motor tests), physical activity (step count), health-related quality of life (SF-8), fall-related self-efficacy (FES-I), and exercise self-efficacy (SSA-Scale). The hypothesis that there will be differences between the two groups (experimental/control) with respect to post-interventional chair-rise time will be tested using an ANCOVA with chair-rise time at baseline, treatment group, and study centre effects as explanatory variables. Analysis of the data will be undertaken using the principle of intention-to-treat. Trial registration Current Controlled Trials ISRCTN17727272. PMID:22188781

Although it is highly preventable and treatable, cervical cancer is the most common and most deadly cancer among women in Rwanda. By mobilizing a diverse coalition of partnerships, Rwanda became the first country in Africa to develop and implement a national strategic plan for cervical cancer prevention, screening and treatment. Rwanda - a small, landlocked nation in East Africa with a population of 10.4 million - is well positioned to tackle a number of "high-burden" noncommunicable diseases. The country's integrated response to infectious diseases has resulted in steep declines in premature mortality over the past decade. In 2011-2012, Rwanda vaccinated 227,246 girls with all three doses of the human papillomavirus (HPV) vaccine. Among eligible girls, three-dose coverage rates of 93.2% and 96.6% were achieved in 2011 and 2012, respectively. The country has also initiated nationwide screening and treatment programmes that are based on visual inspection of the cervix with acetic acid, testing for HPV DNA, cryotherapy, the loop electrosurgical excision procedure and various advanced treatment options. Low-income countries should begin to address cervical cancer by integrating prevention, screening and treatment into routine women's health services. This requires political will, cross-sectoral collaboration and planning, innovative partnerships and robust monitoring and evaluation. With external support and adequate planning, high nationwide coverage rates for HPV vaccination and screening for cervical cancer can be achieved within a few years.

A novel 3D imaging system for strawberry phenotyping.

Accurate and quantitative phenotypic data in plant breeding programmes is vital in breeding to assess the performance of genotypes and to make selections. Traditional strawberry phenotyping relies on the human eye to assess most external fruit quality attributes, which is time-consuming and subjective. 3D imaging is a promising high-throughput technique that allows multiple external fruit quality attributes to be measured simultaneously. A low cost multi-view stereo (MVS) imaging system was developed, which captured data from 360° around a target strawberry fruit. A 3D point cloud of the sample was derived and analysed with custom-developed software to estimate berry height, length, width, volume, calyx size, colour and achene number. Analysis of these traits in 100 fruits showed good concordance with manual assessment methods. This study demonstrates the feasibility of an MVS based 3D imaging system for the rapid and quantitative phenotyping of seven agronomically important external strawberry traits. With further improvement, this method could be applied in strawberry breeding programmes as a cost effective phenotyping technique.

2015-01-01

We present a programmable microfluidic static droplet array (SDA) device that can perform user-defined multistep combinatorial protocols. It combines the passive storage of aqueous droplets without any external control with integrated microvalves for discrete sample dispensing and dispersion-free unit operation. The addressable picoliter-volume reaction is systematically achieved by consecutively merging programmable sequences of reagent droplets. The SDA device is remarkably reusable and able to perform identical enzyme kinetic experiments at least 30 times via automated cross-contamination-free removal of droplets from individual hydrodynamic traps. Taking all these features together, this programmable and reusable universal SDA device will be a general microfluidic platform that can be reprogrammed for multiple applications.

Philip Morris' new scientific initiative: an analysis

2001-01-01

In the fall of 2000, Philip Morris re-initiated an external research grants programme ("Philip Morris External Research Program", or PMERP), the first since the dissolution of the Council for Tobacco Research (CTR) and the Center for Indoor Air Research (CIAR). The ostensible purpose of the programme is to help develop cigarette designs "that might reduce the health risk of smoking". Internal company documents also indicate that Philip Morris urgently seeks to restore its scientific "credibility", as part of a "new openness" in relation to the external community. The structure of the review panel—a cohort of external peer reviewers, a science advisory board, and an internal, anonymous review and approvals committee—is nearly identical to that of the CIAR. The majority of the named reviewers have had previous affiliation with the tobacco industry either as reviewers or grantees, but only a minority have done research directly on tobacco or smoking. The programmatic substance of the PMERP could be interpreted as soliciting exculpatory evidence with respect to smoking and exposure to smoke. We remain sceptical about the scientific integrity of PMERP.

Interpersonal conflicts at work as a predictor of self-reported health outcomes and occupational mobility.

PubMed

De Raeve, L; Jansen, N W H; van den Brandt, P A; Vasse, R; Kant, I J

2009-01-01

The aim of this prospective study was to examine the relationship between interpersonal conflicts at work and subsequent self-reported health outcomes (self-reported general health, need for recovery, and prolonged fatigue) and occupational mobility (internal mobility ie, changing job function, and external mobility ie, changing employers). Data from the Maastricht Cohort Study on fatigue at work (n = 5582 for co-worker conflict; n = 5530 for supervisor conflict) were used. Interpersonal conflict with either co-workers or supervisors was assessed between baseline and 1-year follow-up. Outcomes were studied every 4 months between 1-year and 2-year follow-up. Logistic regression analyses using generalised estimating equations were conducted for each of the dichotomous outcomes, while controlling for demographic factors, the presence of a long-term illness, other workplace stressors, coping, and outcome at baseline. Analyses were conducted for men only. At baseline, conflicts with co-workers occurred in 7.2% of the study population, while conflicts with supervisors occurred in 9.5% of the study population. In general, this study showed that co-worker conflict was a statistically significant risk factor for the onset of an elevated need for recovery, prolonged fatigue, poor general health and external occupational mobility. Supervisor conflict was a significant risk factor for the onset of an elevated need for recovery, prolonged fatigue, external occupational mobility, and internal occupational mobility. The results of this study indicate a possible causal relationship between interpersonal conflicts at work and self-reported health and occupational mobility. Given the considerable impact of interpersonal conflicts at work on the individual worker and on the organisation, and the fact that interpersonal conflicts at work are highly prevalent, these findings underline the need for interventions aimed at preventing the occurrence of interpersonal conflicts at work, or at least reducing the harmful effects on both the employee and the organisation.

Knowledge mobilized by a critical thinking process deployed by nursing students in practical care situations: a qualitative study.

PubMed

Lechasseur, Kathleen; Lazure, Ginette; Guilbert, Louise

2011-09-01

This paper is a report of a qualitative study of mobilization of knowledge within the critical thinking process deployed by female undergraduate nursing students in practical care situations. Holistic practice is based on variety of knowledge mobilized by a critical thinking process. Novices and, more specifically, students experience many difficulties in this regard. Therefore, a better understanding of the knowledge they mobilize in their practice is important for nurse educators. A qualitative study, guided by grounded theory, was carried out. Sixteen nursing students, registered in an undergraduate programme in an Eastern Canadian university, were recruited. Descriptions of practical care situations were obtained through explicitation interviews in 2007. A sociodemographic questionnaire, semi-structured interviews and field notes were also used. Data were analysed using an approach based on grounded theory. An additional stage of analysis involved data condensation. Various types of knowledge guide nursing students' practice. These include intrapersonal, interpersonal, perceptual, moral/ethical, experiential, practical, scientific and contextual knowledge. The mobilization of these types of knowledge is only possible when the process of critical thinking has attained a higher level, giving rise to a new knowledge that we have termed combinational constructive knowledge rather than aesthetic knowledge. Clarification of the types of knowledge guiding the practice of student nurses and of the role of critical thinking in their mobilization could lead to innovative educational strategies. The findings provide guidance for the revision and development of both academic and clinical training programmes. © 2011 Blackwell Publishing Ltd.

Addressing the social determinants of health: a case study from the Mitanin (community health worker) programme in India.

PubMed

Nandi, Sulakshana; Schneider, Helen

2014-09-01

The Mitanin Programme, a government community health worker (CHW) programme, was started in Chhattisgarh State of India in 2002. The CHWs (Mitanins) have consistently adopted roles that go beyond health programme-specific interventions to embrace community mobilization and action on local priorities. The aim of this research was to document how and why the Mitanins have been able to act on the social determinants of health, describing the catalysts and processes involved and the enabling programmatic and organizational factors. A qualitative comparative case study of successful action by Mitanin was conducted in two 'blocks', purposefully selected as positive exemplars in two districts of Chhattisgarh. One case focused on malnutrition and the other on gender-based violence. Data collection involved 17 in-depth interviews and 10 group interviews with the full range of stakeholders in both blocks, including community members and programme team. Thematic analysis was done using a broad conceptual framework that was further refined. Action on social determinants involved raising awareness on rights, mobilizing women's collectives, revitalizing local political structures and social action targeting both the community and government service providers. Through these processes, the Mitanins developed identities as agents of change and advocates for the community, both with respect to local cultural and gender norms and in ensuring accountability of service providers. The factors underpinning successful action on social determinants were identified as the significance of the original intent and vision of the programme, and how this was carried through into all aspects of programme design, the role of the Mitanins and their identification with village women, ongoing training and support, and the relative autonomy of the programme. Although the results are not narrowly generalizable and do not necessarily represent the situation of the Mitanin Programme as a whole, the explanatory framework may provide general lessons for programmes in similar contexts.

Developmental timing of housing mobility: longitudinal effects on externalizing behaviors among at-risk youth.

PubMed

Fowler, Patrick J; Henry, David B; Schoeny, Michael; Taylor, Jeremy; Chavira, Dina

2014-02-01

This longitudinal study tested whether developmental timing of exposure to housing mobility exacerbates behavior problems in an at-risk sample of youth. Participants were 2,442 youth 4 to 16 years old at risk for child maltreatment followed at 3 time points over a 36-month follow-up. Caregivers reported on youth externalizing behaviors at each assessment. Latent growth models examined the effect of housing mobility on behavior problems after accounting for change in cognitive development, family instability, child gender, ethnicity, family income, and caregiver mental health at baseline. Findings suggested increased housing mobility predicted greater behavior problems when children were exposed at key developmental periods. Preschoolers exhibited significantly higher rates of behavior problems that remained stable across the 3-year follow-up. Likewise, adolescents exposed to more mobility became relatively more disruptive over time. No effects were found for school-age children. Children who moved frequently during infancy and more recently demonstrated significantly worse behavior over time. The developmental timing of housing mobility affects child behavioral outcomes. Youth in developmental transition at the time of mobility are at greatest risk for disturbances to residential contexts. Assessing housing history represents an important component of interventions with at-risk families. Copyright © 2014 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc.

Today's generation of young adults are gaining weight faster than their parents; however, there remains insufficient evidence to inform interventions to prevent this weight gain. Mobile phones are a popular means of communication that may provide a convenient, inexpensive means to deliver health intervention programmes. This pilot study aimed to measure the effect of a 12-week mobile health (mHealth) intervention on body weight, body mass index and specific lifestyle behaviours addressed by the programme. University students and staff aged 18-35 years (n = 51) were randomised (ratio 1 : 1, intervention : control). Both groups received a printed diet booklet with instructions prepared by a dietitian. The intervention group also received Short Message Service (SMS) text messages (four per week), e-mails (four per week), and had access to smartphone applications and Internet forums. Pre- to post-intervention, participants in the intervention group decreased their body weight [mean (SD)] [-1.6 (2.6) kg], increased their light intensity activity [34 (35) min day(-1)] and reported an increased vegetable (1.0 median serving day(-1)) and decreased sugar-sweetened beverage intake [-355 (836) mL week(-1)]. Despite this, post-intervention changes in outcomes were not significantly different from controls. The piloted mHealth programme provided some short-term positive changes in weight, nutrition and physical activity using a low cost, convenient delivery method for this population. However, changes were no different from those observed among controls. This might partly be explained by intervention participants' low engagement with the programme, which is likely to require further modification to provide more regular, personalised, monitored support. © 2013 The British Dietetic Association Ltd.

General and Direct Method for Preparing Oligonucleotide-Functionalized Metal–Organic Framework Nanoparticles

PubMed Central

2017-01-01

Metal–organic frameworks (MOFs) are a class of modular, crystalline, and porous materials that hold promise for storage and transport of chemical cargoes. Though MOFs have been studied in bulk forms, ways of deliberately manipulating the external surface functionality of MOF nanoparticles are less developed. A generalizable approach to modify their surfaces would allow one to impart chemical functionality onto the particle surface that is independent of the bulk MOF structure. Moreover, the use of a chemically programmable ligand, such as DNA, would allow for the manipulation of interparticle interactions. Herein, we report a coordination chemistry-based strategy for the surface functionalization of the external metal nodes of MOF nanoparticles with terminal phosphate-modified oligonucleotides. The external surfaces of nine distinct archetypical MOF particles containing four different metal species (Zr, Cr, Fe, and Al) were successfully functionalized with oligonucleotides, illustrating the generality of this strategy. By taking advantage of the programmable and specific interactions of DNA, 11 distinct MOF particle–inorganic particle core–satellite clusters were synthesized. In these hybrid nanoclusters, the relative stoichiometry, size, shape, and composition of the building blocks can all be independently controlled. This work provides access to a new set of nucleic acid–nanoparticle conjugates, which may be useful as programmable material building blocks and as probes for measuring and manipulating intracellular processes.

Peer mentors, mobile phone and pills: collective monitoring and adherence in Kenyatta National Hospital's HIV treatment programme

Moyer, Eileen

2014-01-01

In 2006, the Kenyan state joined the international commitment to make antiretroviral treatment free in public health institutions to people infected with HIV. Less than a decade later, treatment has reached over 60% of those who need it in Kenya. This paper, which is based on an in-depth ethnographic case study of the HIV treatment programme at Kenyatta National Hospital, conducted intermittently between 2008 and 2014, examines how HIV-positive peer mentors encourage and track adherence to treatment regimens within and beyond the clinic walls using mobile phones and computer technology. This research into the everyday practices of patient monitoring demonstrates that both surveillance and adherence are collective activities. Peer mentors provide counselling services, follow up people who stray from treatment regimens, and perform a range of other tasks related to patient management and treatment adherence. Despite peer mentors’ involvement in many tasks key to encouraging optimal adherence, their role is rarely acknowledged by co-workers, hospital administrators, or public health officials. Following a biomedical paradigm, adherence at Kenyatta and in Kenya is framed by programme administrators as something individual clients must do and for which they must be held accountable. This framing simultaneously conceals the sociality of adherence and undervalues the work of peer mentors in treatment programmes. PMID:25175291

There is growing recognition that operational research (OR) should be embedded into national disease control programmes. However, much of the current OR capacity building schemes are still predominantly driven by international agencies with limited integration into national disease control programmes. We demonstrated that it is possible to achieve a more sustainable capacity building effort across the country by establishing an OR group within the national tuberculosis (TB) control programme in Indonesia. Key challenges identified include long-term financial support, limited number of scientific publications, and difficulties in documenting impact on programmatic performance. External evaluation has expressed concerns in regard to utilisation of OR in policy making. Efforts to address this concern have been introduced recently and led to indications of increased utilisation of research evidence in policy making by the national TB control programme. Embedding OR in national disease control programmes is key in establishing an evidence-based disease control programme. PMID:25361728

Mobile Context Provider for Social Networking

NASA Astrophysics Data System (ADS)

Santos, André C.; Cardoso, João M. P.; Ferreira, Diogo R.; Diniz, Pedro C.

The ability to infer user context based on a mobile device together with a set of external sensors opens up the way to new context-aware services and applications. In this paper, we describe a mobile context provider that makes use of sensors available in a smartphone as well as sensors externally connected via bluetooth. We describe the system architecture from sensor data acquisition to feature extraction, context inference and the publication of context information to well-known social networking services such as Twitter and Hi5. In the current prototype, context inference is based on decision trees, but the middleware allows the integration of other inference engines. Experimental results suggest that the proposed solution is a promising approach to provide user context to both local and network-level services.

The national Quality Control (QC) programme for radionuclide calibrators started 12 years ago. Accuracy and the implementation of a QC programme were evaluated over all these years at 95 nuclear medicine laboratories where dose calibrators were in use. During all that time, the Metrology Group of CNEA has distributed 137Cs sealed sources to check stability and has been performing periodic "checking rounds" and postal surveys using unknown samples (external quality control). An account of the results of both methods is presented. At present, more of 65% of the dose calibrators measure activities with an error less than 10%.

Background Since 2002, development assistance for health has substantially increased, especially investments for HIV, tuberculosis (TB) and malaria control. We undertook a systematic review to assess and synthesize the existing evidence in the scientific literature on the health impacts of these investments. Methods and findings We systematically searched databases for peer-reviewed and grey literature, using tailored search strategies. We screened studies for study design and relevance, using predefined inclusion criteria, and selected those that enabled us to link health outcomes or impact to increased external funding. For all included studies, we recorded dataset and study characteristics, health outcomes and impacts. We analysed the data using a causal-chain framework to develop a narrative summary of the published evidence. Thirteen articles, representing 11 individual studies set in Africa and Asia reporting impacts on HIV, tuberculosis and malaria, met the inclusion criteria. Only two of these studies documented the entire causal-chain spanning from funding to programme scale-up, to outputs, outcomes and impacts. Nonetheless, overall we find a positive correlation between consecutive steps in the causal chain, suggesting that external funds for HIV, tuberculosis and malaria programmes contributed to improved health outcomes and impact. Conclusions Despite the large number of supported programmes worldwide and despite an abundance of published studies on HIV, TB and malaria control, we identified very few eligible studies that adequately demonstrated the full process by which external funding has been translated to health impact. Most of these studies did not move beyond demonstrating statistical association, as opposed to contribution or causation. We thus recommend that funding organizations and researchers increase the emphasis on ensuring data capture along the causal pathway to demonstrate effect and contribution of external financing. The findings of these comprehensive and rigorously conducted impact evaluations should also be made publicly accessible. PMID:23921987

Summary Background Rheumatic heart disease (RHD) remains a major disease burden in low-resource settings globally. Patient registers have long been recognised to be an essential instrument in RHD control and elimination programmes, yet to date rely heavily on paper-based data collection and non-networked data-management systems, which limit their functionality. Objectives To assess the feasibility and potential benefits of producing an electronic RHD patient register. Methods We developed an eRegister based on the World Heart Federation’s framework for RHD patient registers using CommCare, an open-source, cloud-based software for health programmes that supports the development of customised data capture using mobile devices. Results The resulting eRegistry application allows for simultaneous data collection and entry by field workers using mobile devices, and by providers using computer terminals in clinics and hospitals. Data are extracted from CommCare and are securely uploaded into a cloud-based database that matches the criteria established by the WHF framework. The application can easily be tailored to local needs by modifying existing variables or adding new ones. Compared with traditional paper-based data-collection systems, the eRegister reduces the risk of data error, synchronises in real-time, improves clinical operations and supports management of field team operations. Conclusions The user-friendly eRegister is a low-cost, mobile, compatible platform for RHD treatment and prevention programmes based on materials sanctioned by the World Heart Federation. Readily adaptable to local needs, this paperless RHD patient register program presents many practical benefits. PMID:26444995

On the use of mobile phones and wearable microphones for noise exposure measurements: Calibration and measurement accuracy

NASA Astrophysics Data System (ADS)

Dumoulin, Romain

Despite the fact that noise-induced hearing loss remains the number one occupational disease in developed countries, individual noise exposure levels are still rarely known and infrequently tracked. Indeed, efforts to standardize noise exposure levels present disadvantages such as costly instrumentation and difficulties associated with on site implementation. Given their advanced technical capabilities and widespread daily usage, mobile phones could be used to measure noise levels and make noise monitoring more accessible. However, the use of mobile phones for measuring noise exposure is currently limited due to the lack of formal procedures for their calibration and challenges regarding the measurement procedure. Our research investigated the calibration of mobile phone-based solutions for measuring noise exposure using a mobile phone's built-in microphones and wearable external microphones. The proposed calibration approach integrated corrections that took into account microphone placement error. The corrections were of two types: frequency-dependent, using a digital filter and noise level-dependent, based on the difference between the C-weighted noise level minus A-weighted noise level of the noise measured by the phone. The electro-acoustical limitations and measurement calibration procedure of the mobile phone were investigated. The study also sought to quantify the effect of noise exposure characteristics on the accuracy of calibrated mobile phone measurements. Measurements were carried out in reverberant and semi-anechoic chambers with several mobiles phone units of the same model, two types of external devices (an earpiece and a headset with an in-line microphone) and an acoustical test fixture (ATF). The proposed calibration approach significantly improved the accuracy of the noise level measurements in diffuse and free fields, with better results in the diffuse field and with ATF positions causing little or no acoustic shadowing. Several sources of errors and uncertainties were identified including the errors associated with the inter-unit-variability, the presence of signal saturation and the microphone placement relative to the source and the wearer. The results of the investigations and validation measurements led to recommendations regarding the measurement procedure including the use of external microphones having lower sensitivity and provided the basis for a standardized and unique factory default calibration method intended for implementation in any mobile phone. A user-defined adjustment was proposed to minimize the errors associated with calibration and the acoustical field. Mobile phones implementing the proposed laboratory calibration and used with external microphones showed great potential as noise exposure instruments. Combined with their potential as training and prevention tools, the expansion of their use could significantly help reduce the risks of noise-induced hearing loss.

AEDs at your fingertips: automated external defibrillators on college campuses and a novel approach for increasing accessibility.

Berger, Ryan J; O'Shea, Jesse G

2014-01-01

The use of automated external defibrillators (AEDs) increases survival in cardiac arrest events. Due to the success of previous efforts and free, readily available mobile mapping software, the discussion is to emphasize the importance of the use of AEDs to prevent sudden cardiac arrest-related deaths on college campuses and abroad, while suggesting a novel approach to aiding in access and awareness issues. A user-friendly mobile application (a low-cost iOS map) was developed at Florida State University to decrease AED retrieval distance and time. The development of mobile AED maps is feasible for a variety of universities and other entities, with the potential to save lives. Just having AEDs installed is not enough--they need to be easily locatable. Society increasingly relies on phones to provide information, and there are opportunities to use mobile technology to locate and share information about relevant emergency devices; these should be incorporated into the chain of survival.

Protection of Mobile Agents Execution Using a Modified Self-Validating Branch-Based Software Watermarking with External Sentinel

NASA Astrophysics Data System (ADS)

Tomàs-Buliart, Joan; Fernández, Marcel; Soriano, Miguel

Critical infrastructures are usually controlled by software entities. To monitor the well-function of these entities, a solution based in the use of mobile agents is proposed. Some proposals to detect modifications of mobile agents, as digital signature of code, exist but they are oriented to protect software against modification or to verify that an agent have been executed correctly. The aim of our proposal is to guarantee that the software is being executed correctly by a non trusted host. The way proposed to achieve this objective is by the improvement of the Self-Validating Branch-Based Software Watermarking by Myles et al.. The proposed modification is the incorporation of an external element called sentinel which controls branch targets. This technique applied in mobile agents can guarantee the correct operation of an agent or, at least, can detect suspicious behaviours of a malicious host during the execution of the agent instead of detecting when the execution of the agent have finished.

Does external walking environment affect gait patterns?

The objective of this work is to develop an understanding of the relationship between mobility metrics obtained outside of the clinic or laboratory and the context of the external environment. Ten subjects walked with an inertial sensor on each shank and a wearable camera around their neck. They were taken on a thirty minute walk in which they mobilized over the following conditions; normal path, busy hallway, rough ground, blind folded and on a hill. Stride time, stride time variability, stance time and peak shank rotation rate during swing were calculated using previously published algorithms. Stride time was significantly different between several of the conditions. Technological advances mean that gait variables can now be captured as patients go about their daily lives. The results of this study show that the external environment has a significant impact on the quality of gait metrics. Thus, context of external walking environment is an important consideration when analyzing ambulatory gait metrics from the unsupervised home and community setting.

Physiological Effects of Early Incremental Mobilization of a Patient with Acute Intracerebral and Intraventricular Hemorrhage Requiring Dual External Ventricular Drainage.

Recent trials have challenged the notion that very early mobility benefits patients with acute stroke. It is unclear how cerebral autoregulatory impairments, prevalent in this population, could be affected by mobilization. The safety of mobilizing patients who have external ventricular drainage (EVD) devices for cerebrospinal fluid diversion and intracranial pressure (ICP) monitoring is another concern due to risk of device dislodgment and potential elevation in ICP. We report hemodynamic and ICP responses during progressive, device-assisted mobility interventions performed in a critically ill patient with intracerebral hemorrhage (ICH) requiring two EVDs. A 55-year-old man was admitted to the Neuroscience Critical Care Unit with an acute thalamic ICH and complex intraventricular hemorrhage requiring placement of two EVDs. Progressive mobilization was achieved using mobility technology devices. Range of motion exercises were performed initially, progressing to supine cycle ergometry followed by incremental verticalization using a tilt table. Physiological parameters were recorded before and after the interventions. All mobility interventions were completed without any adverse event or clinically detectable change in the patient's neurological state. Physiological parameters including hemodynamic variables and ICP remained within prescribed goals throughout. Progressive, device-assisted early mobilization was feasible and safe in this critically ill patient with hemorrhagic stroke when titrated by an interdisciplinary team of skilled healthcare professionals. Studies are needed to gain insight into the hemodynamic and neurophysiological responses associated with early mobility in acute stroke to identify subsets of patients who are most likely to benefit from this intervention.

How nurses restore and maintain mobility in hospitalised older people: An integrative literature review.

PubMed

Constantin, Stephanie; Dahlke, Sherry

2018-05-17

The aim of this integrative review of the literature was to evaluate and summarise current research about how nurses maintain and improve hospitalised older peoples' mobility levels. Older persons make up the majority of healthcare recipients, and they are at risk to experience significant decline in their mobility once hospitalised. This can result in longer hospitalisations or nursing home admissions. Currently, it is not well understood how nurses maintain and restore mobility of hospitalised older persons. An integrative literature review using key concepts related to hospitalised older people, mobility and nursing care was conducted. Whittemore and Khalf's five-stage methodological framework for integrative reviews was utilised. Two reviewers screened 1640 resources from four computerised databases published in English during 2000-2017. Reviewers used the Mixed Methods Appraisal Tool (MMAT) and CASP quality appraisal tools to assess the thirteen included articles. The findings of this review reveal that little is known about how frequently nurses are mobilising, that many nurses perceive mobilising older patients to be physiotherapy's responsibility and that education about mobilisation can improve nurses' willingness to mobilise people. By investing in education and training programmes targeted for nurses, nurses can feel empowered in their ability to mobilise patients and are encouraged to take ownership of their patient's functional needs. In order to facilitate mobility, adequate staffing levels are necessary for transferring and ambulation, mobility assistive devices such as walkers and canes and environments with adequate space to mobilise. More research is needed to better understand and overcome barriers that nurses face in mobilised older people in acute care. The nursing team can work together to prioritise mobilisation to assist in restoring and maintaining the function of hospitalised older people. Educators could review their mobility programmes to increase graduate nurses' confidence and self-efficacy in mobility assessments and thus prepare graduate nurses for the realities of practice. © 2018 John Wiley & Sons Ltd.

To identify where vouchers have been used for reproductive health (RH) services, to what extent RH voucher programmes have been evaluated, and whether the programmes have been effective. A systematic search of the peer review and grey literature was conducted to identify RH voucher programmes and evaluation findings. Experts were consulted to verify RH voucher programme information and identify further programmes and studies not found in the literature search. Studies were examined for outcomes regarding targeting, costs, knowledge, utilization, quality, and population health impact. Included studies used cross-sectional, before-and-after and quasi-experimental designs. Thirteen RH voucher programmes fitting established criteria were identified. RH voucher programmes were located in Bangladesh, Cambodia, China, Kenya (2), Korea, India, Indonesia, Nicaragua (3), Taiwan, and Uganda. Among RH voucher programmes, 7 were quantitatively evaluated in 15 studies. All evaluations reported some positive findings, indicating that RH voucher programmes increased utilization of RH services, improved quality of care, and improved population health outcomes. The potential for RH voucher programmes appears positive; however, more research is needed to examine programme effectiveness using strong study designs. In particular, it is important to see stronger evidence on cost-effectiveness and population health impacts, where the findings can best direct governments and external funders. © 2010 Blackwell Publishing Ltd.

Both mobile apps and responsive-design websites (web apps) can be used to deliver mobile health (mHealth) interventions, but it can be difficult to discern which to use in research. The goal of this paper is to present four case studies from behavioral interventions that developed either a mobile app or a web app for research and present an information table to help researchers determine which mobile option would work best for them. Four behavioral intervention case studies (two developed a mobile app, and two developed a web app) presented include time, cost, and expertise. Considerations for adopting a mobile app or a web app-such as time, cost, access to programmers, data collection, security needs, and intervention components- are presented. Future studies will likely integrate both mobile app and web app modalities. The considerations presented here can help guide researchers on which platforms to choose prior to starting an mHealth intervention.

Factors affecting the impingement angle of fixed- and mobile-bearing total knee replacements: a laboratory study.

PubMed

2007-08-01

Maximum flexion-or impingement angle-is defined as the angle of flexion when the posterior femoral cortex impacts the posterior edge of the tibial insert. We examined the effects of femoral component placement on the femur, the slope angle of the tibial component, the location of the femoral-tibial contact point, and the amount of internal or external rotation. Posterior and proximal femoral placement, a more posterior femoral-tibial contact point, and a more tibial slope all increased maximum flexion, whereas rotation reduced it. A mobile-bearing knee gave results similar to those of the fixed-bearing knee, but there was no loss of flexion in internal or external rotation if the mobile bearing moved with the femur. In the absence of negative factors, a flexion angle of 150 degrees can be reached before impingement.

Mobile phone health risk policy in Germany: the role of the federal government and the Federal Office for Radiation Protection.

PubMed

Schweikardt, Christoph; Gross, Dominik

2012-01-01

In order to establish a regulatory framework for a given technology important to society, the government must make decisions in the face of existing unknowingness. In the last decade, health risks originating from electromagnetic fields of mobile telecommunication transmitting stations and devices have become a regulation policy issue in Germany. This article investigates the role of the government and the Federal Office for Radiation Protection in regard to policy-making by analysing publications and Federal Parliament reports, hearings and debates. The government and Federal Parliament perceived the research situation in 2001 as insufficient in the absence of hard evidence for health impairment. Against this background, the government struck a compromise with mobile telecommunication network operators, who did not want to integrate stricter limit values for transmission stations as precautionary measures. The network operators' voluntary self-commitment included financing half the budget of the German Mobile Telecommunication Research Programme (2002-2008) under the lead management of the Federal Office for Radiation Protection, which concluded that it was not required to change the position taken in 2001. The results of this programme provided the basis to continue the agreement of that year. With regard to health issues and all the other interests involved, this agreement was an acceptable and remarkably stable compromise.

The use of mobile phones to deliver acceptance and commitment therapy in the prevention of mother-child HIV transmission in Nigeria.

Ishola, A G; Chipps, J

2015-12-01

The objective of this study was to determine if introducing acceptance and commitment therapy in the prevention of mother to child HIV transmission (PMTCT) programme using weekly mobile phone messages would result in improved mental health status of HIV-positive, pregnant women in Nigeria. We used a Solomon four-group (two intervention and two control groups) randomised design. The study population was 144 randomly selected, HIV-positive pregnant women attending four randomly selected PMTCT centres in Nigeria. The intervention groups were exposed to one session of acceptance and commitment therapy with weekly value-based health messages sent by mobile phone for three months during pregnancy. The control groups received only post-HIV test counselling. A total of 132 participants (33 per site) were enrolled in the study from the two intervention and two control sites. In the pre-tests, the intervention and control groups did not differ significantly with regard to demographics. Evaluation of the pre- and post-tests of the intervention group indicated significantly higher Action and Acceptance Questionnaire (AAQ-II) scores.

A high angular resolution ranging system particularly suitable for indoor plications involving mobile robot navigation and collision avoidance uses a programmable array of light emitters that can be sequentially incremented by a microprocessor. A plurality of adjustable level threshold detectors are used in an optical receiver for detecting the threshold level of the light echoes produced when light emitted from one or more of the emitters is reflected by a target or object in the scan path of the ranging system.

Precise localization of mobile tumor positions in real time is critical to the success of gated radiotherapy. Tumor positions are usually derived from either internal or external surrogates. Fluoroscopic gating based on internal surrogates, such as implanted fiducial markers, is accurate however requiring a large amount of imaging dose. Gating based on external surrogates, such as patient abdominal surface motion, is non-invasive however less accurate due to the uncertainty in the correlation between tumor location and external surrogates. To address these complications, we propose to investigate an approach based on hybrid gating with dynamic internal/external correlation updates. In this approach, the external signal is acquired at high frequency (such as 30 Hz) while the internal signal is sparsely acquired (such as 0.5 Hz or less). The internal signal is used to validate and update the internal/external correlation during treatment. Tumor positions are derived from the external signal based on the newly updated correlation. Two dynamic correlation updating algorithms are introduced. One is based on the motion amplitude and the other is based on the motion phase. Nine patients with synchronized internal/external motion signals are simulated retrospectively to evaluate the effectiveness of hybrid gating. The influences of different clinical conditions on hybrid gating, such as the size of gating windows, the optimal timing for internal signal acquisition and the acquisition frequency are investigated. The results demonstrate that dynamically updating the internal/external correlation in or around the gating window will reduce false positive with relatively diminished treatment efficiency. This improvement will benefit patients with mobile tumors, especially greater for early stage lung cancers, for which the tumors are less attached or freely floating in the lung.

Since 2005, the Myanmar National Tuberculosis Programme (NTP) has been implementing active case finding (ACF) activities involving mobile teams in hard-to-reach areas. This study revealed the contribution of mobile team activities to total tuberculosis (TB) case detection, characteristics of TB patients detected by mobile teams and their treatment outcomes. This was a descriptive study using routine programme data between October 2014 and December 2014. Mobile team activities were a one-stop service and included portable digital chest radiography (CXR) and microscopy of two sputum samples. The algorithm of the case detection included screening patients by symptoms, then by CXR followed by sputum microscopy for confirmation. Diagnosed patients were started on treatment and followed until a final outcome was ascertained. A total of 9 349 people with symptoms suggestive of TB were screened by CXR, with an uptake of 96.6%. Of those who were meant to undergo sputum smear microscopy, 51.4% had sputum examinations. Finally, 504 TB patients were identified by the mobile teams and the overall contribution to total TB case detection in the respective townships was 25.3%. Among total cases examined by microscopy, 6.4% were sputum smear positive TB. Treatment success rate was high as 91.8% in study townships compared to national rate 85% (2014 cohort). This study confirmed the feasibility and acceptability of ACF by mobile teams in hard-to-reach contexts, especially when equipped with portable, digital CXR machines that provided immediate results. However, the follow-up process of sputum examination created a significant barrier to confirmation of the diagnosis. In order to optimize the ACF through mobile team activity, future ACF activities were needed to be strengthened one stop service including molecular diagnostics or provision of sputum cups to all presumptive TB cases prior to CXR and testing if CXR suggestive of TB.

The paper describes a method for the reducing emission of low-frequency noise of modern automotive vehicles into the environment. The importance of reducing the external noise of modern mobile energy facilities made in Russia is substantiated. Standard methods for controlling external noise in technology are of low efficiency when low-frequency sound waves are reduced. In this case, it is in the low-frequency zone of the sound range that the main power of the noise emitted by the machinery lies. The most effective way to reduce such sound waves is to use active noise control systems. A design of a muffler using a similar system is presented. This muffler allowed one to reduce the emission of increased noise levels into the environment by 7-11 dB and to increase acoustic comfort at the operator's workplace by 3-5 dB.

Community services provide essential care to many, often vulnerable, people, families and communities along the spectrum from health promotion to end of life care. The Mobile Health Worker Project is part of a larger project, the Transforming Community Services programme, which was established to support providers make changes to service provision that would provide better health outcomes, as well as increasing efficiency through the use of technology. This paper draws on the results of the two phase Mobile Health Worker project which involved 11 sites around England, the aim of which was to understand the requirements of mobile working. The results demonstrate that increased productivity and efficiency can be achieved by making changes to working processes. The project also provides guidance to increase the rate of mobile working adoption by providing a solid economic basis for investment in and deployment of mobile solutions to community organisations.

The purpose of this paper is to reflect upon a workplace-based, interdisciplinary clinical leadership training programme (CLP) to increase willingness to take on leadership roles in a large regional health-care centre in Victoria, Australia. Strengthening the leadership capacity of clinical staff is an advocated strategy for improving patient safety and quality of care. An interdisciplinary approach to leadership is increasingly emphasised in the literature; however, externally sourced training programmes are expensive and tend to target a single discipline. Appraisal of the first two years of CLP using multiple sourced feedback. A structured survey questionnaire with closed-ended questions graded using a five-point Likert scale was completed by participants of the 2012 programme. Participants from the 2011 programme were followed up for 18 months after completion of the programme to identify the uptake of new leadership roles. A reflective session was also completed by a senior executive staff that supported the implementation of the programme. Workplace-based CLP is a low-cost and multidisciplinary alternative to externally sourced leadership courses. The CLP significantly increased willingness to take on leadership roles. Most participants (93 per cent) reported that they were more willing to take on a leadership role within their team. Fewer were willing to lead at the level of department (79 per cent) or organisation (64 per cent). Five of the 11 participants from the 2011 programme had taken on a new leadership role 18 months later. Senior executive feedback was positive especially around the engagement and building of staff confidence. They considered that the CLP had sufficient merit to support continuation for at least another two years. Integrating health-care professionals into formal and informal leadership roles is essential to implement organisational change as part of the drive to improve the safety and quality of care for patients and service users. This is the first interdisciplinary, workplace-based leadership programme to be described in the literature, and demonstrates that it is possible to deliver low-cost, sustainable and productive training that increases the willingness to take on leadership roles.

Mobil Corp. has unveiled a new etherification technology that can produce fuel oxygenated based only on olefinic refinery streams and water. The process has the potential to allow refiners to produce oxygenates without having to rely on an external supply of alcohols such as methanol or ethanol. Mobil has developed the technology around a new oxygenate, disopropyl ether (DIPE), based on propylene. However, the process has also been tested using mixed propylene/C{sub 4} and straight C{sub 4} streams, says Michael J. McNally, manager of Mobil`s Motor Gasoline Group (Paulsboro, NJ), producing ethers analogous to methyl tert-butyl ether (MTBE).

This paper presents the use of an external fixed two-dimensional laser scanner to detect cylindrical targets attached to moving devices, such as a mobile robot. This proposal is based on the detection of circular markers in the raw data provided by the laser scanner by applying an algorithm for outlier avoidance and a least-squares circular fitting. Some experiments have been developed to empirically validate the proposal with different cylindrical targets in order to estimate the location and tracking errors achieved, which are generally less than 20 mm in the area covered by the laser sensor. As a result of the validation experiments, several error maps have been obtained in order to give an estimate of the uncertainty of any location computed. This proposal has been validated with a medium-sized mobile robot with an attached cylindrical target (diameter 200 mm). The trajectory of the mobile robot was estimated with an average location error of less than 15 mm, and the real location error in each individual circular fitting was similar to the error estimated with the obtained error maps. The radial area covered in this validation experiment was up to 10 m, a value that depends on the radius of the cylindrical target and the radial density of the distance range points provided by the laser scanner but this area can be increased by combining the information of additional external laser scanners.

Person mobility in the design and analysis of cluster-randomized cohort prevention trials.

2012-06-01

Person mobility is an inescapable fact of life for most cluster-randomized (e.g., schools, hospitals, clinic, cities, state) cohort prevention trials. Mobility rates are an important substantive consideration in estimating the effects of an intervention. In cluster-randomized trials, mobility rates are often correlated with ethnicity, poverty and other variables associated with disparity. This raises the possibility that estimated intervention effects may generalize to only the least mobile segments of a population and, thus, create a threat to external validity. Such mobility can also create threats to the internal validity of conclusions from randomized trials. Researchers must decide how to deal with persons who leave study clusters during a trial (dropouts), persons and clusters that do not comply with an assigned intervention, and persons who enter clusters during a trial (late entrants), in addition to the persons who remain for the duration of a trial (stayers). Statistical techniques alone cannot solve the key issues of internal and external validity raised by the phenomenon of person mobility. This commentary presents a systematic, Campbellian-type analysis of person mobility in cluster-randomized cohort prevention trials. It describes four approaches for dealing with dropouts, late entrants and stayers with respect to data collection, analysis and generalizability. The questions at issue are: 1) From whom should data be collected at each wave of data collection? 2) Which cases should be included in the analyses of an intervention effect? and 3) To what populations can trial results be generalized? The conclusions lead to recommendations for the design and analysis of future cluster-randomized cohort prevention trials.

Findings of a study of the impact of professional learning on Malaysian registered nurses are reported. The offshore delivery post-registration nursing degree programme is a formal aspect of professional learning, which enables Malaysian registered nurses to upgrade their hospital-based training or diploma of nursing qualification to a degree. Using a qualitative case study approach, data were collected from twelve programme graduates, through individual and focus group interviews. The programme promoted their personal professional growth and enhanced their professional development. It increased self-confidence, knowledge, self-fulfillment, critical thinking ability, interpersonal skills, interest in research and research utilisation, and life-long learning. There was evidence of career mobility and a raised awareness of their professional role and responsibility.

Synthetic molecular motors can be fuelled by the hydrolysis or hybridization of DNA. Such motors can move autonomously and programmably, and long-range transport has been observed on linear tracks. It has also been shown that DNA systems can compute. Here, we report a synthetic DNA-based system that integrates long-range transport and information processing. We show that the path of a motor through a network of tracks containing four possible routes can be programmed using instructions that are added externally or carried by the motor itself. When external control is used we find that 87% of the motors follow the correct path, and when internal control is used 71% of the motors follow the correct path. Programmable motion will allow the development of computing networks, molecular systems that can sort and process cargoes according to instructions that they carry, and assembly lines that can be reconfigured dynamically in response to changing demands.

To report an analysis of the concept of distraction of clinicians by smartphones and other mobile devices in hospitals. In the healthcare literature, the concept of distraction of clinicians by smartphones and other mobile devices in hospitals has no consistent definition. Concept analysis. Journal articles published from 2003-2014. Rodgers' Evolutionary Concept Analysis Method was used to analyse the concept of distraction of clinicians by smartphones and other mobile devices in hospitals. This analysis led to a definition of distraction of clinicians by smartphones as the interruption of a hospital clinician's primary task by the internally or externally initiated use of their smartphone or other mobile device. There are six attributes of distraction by smartphones and other mobile devices in hospitals. These attributes are: (1) an experience by a clinician; (2) an intrusion into a primary clinical task; (3) discontinuity of the clinical task; (4) externally or internally initiated; (5) situated in a healthcare setting; and (6) mediated by a smartphone or other mobile device. Use of the definition and the defining attributes of distraction of clinicians by smartphones will increase the validity and reliability of future studies. It will be extended to form a classification system of distractions within a framework of clinical practice, which will be used to unify and standardize future research studies. © 2015 John Wiley & Sons Ltd.

To explore factors influencing participation and attrition in a family-led weight-management programme for obese Pacific children. Qualitative study used bilingual in-depth interviews at exit and end of an 8-week weight-management programme. New Zealand. Forty-two parents/primary caregivers of obese children who were randomised in the intervention weight-management programme. Programmatic factors that enhanced retention included: simultaneous delivery to both children and parents as participants; delivery of the programme in small group settings at local community venues; enabling trustworthy and accountable relationships; providing resources for travel to venues and regular telephone/text messaging follow-up calls reinforcing programme goals; and day and time scheduling. Suggested programme improvements included having ethnic-specific Island-language delivery and practical sessions like cooking classes and shopping expeditions at local food stores. The research found that unpredictable external life crises like extended family deaths, a change in job shift, family illnesses (both acute and those requiring chronic management) and long-term family visitations affected participation and momentum. A loss of momentum through managing life crises was often difficult to overcome for participants, leading them to drop out of the weight-management programme. Most drop-out participants preferred to defer their programme participation with hopes of re-committing to future programmes at another time. In order for weight-management programmes to be effective, participants must be able to complete them. Identifying factors that predict participation and attrition may serve as a basis for programme improvement.

Greater participation in cardiac rehabilitation improves morbidity and mortality in people with coronary heart disease, but little is understood of patients' decisions to participate. To develop interventions aimed at increasing completion of programmes, we conducted a qualitative systematic review and meta-synthesis to explore the complex factors and processes influencing participation in cardiac rehabilitation programmes after referral and initial access. To be included in the review, studies had to contain a qualitative research component, population specific data on programme participation in adults >18 years, and be published ≥1995 as full articles or theses. Ten databases were searched (31 October 2011) using 100+ search terms. Of 2264 citations identified, 62 studies were included involving: 1646 patients (57% female; mean age 64.2), 143 caregivers, and 79 professionals. Patients' participation was most strongly influenced by perceptions of the nature, suitability and scheduling of programmes, social comparisons made possible by programmes, and the degree to which programmes, providers, and programme users met expectations. Women's experiences of these factors rendered them less likely to complete. Comparatively, perceptions of programme benefits had little influence on participation. Factors reducing participation in programmes are varied but amenable to intervention. Participation should be viewed as a 'consumer behaviour' and interventions should mobilize family support, promote 'patient friendly' scheduling, and actively harness the social, identity-related, and experiential aspects of participation.

Few individuals living with mental disorders around the globe have access to mental health care, yet most have access to a mobile phone. Digital technology holds promise for improving access to, and quality of, mental health care. We reviewed evidence on the use of mobile, online, and other remote technologies for treatment and prevention of mental disorders in low-income and middle-income countries. Of the 49 studies identified, most were preliminary evaluations of feasibility and acceptability. The findings were promising, showing the potential effectiveness of online, text-messaging, and telephone support interventions. We summarised the evaluations as: technology for supporting clinical care and educating health workers, mobile tools for facilitating diagnosis and detection of mental disorders, technologies for promoting treatment adherence and supporting recovery, online self-help programmes for individuals with mental disorders, and programmes for substance misuse prevention and treatment. Continued research is needed to rigorously evaluate effectiveness, assess costs, and carefully consider potential risks of digital technology interventions for mental disorders, while determining how emerging technologies might support the scale-up of mental health treatment and prevention efforts across low-resource settings.

Abstract Objective To describe findings from an external quality assessment programme involving laboratories in Africa that routinely investigate epidemic-prone diseases. Methods Beginning in 2002, the Regional Office for Africa of the World Health Organization (WHO) invited national public health laboratories and related facilities in Africa to participate in the programme. Three surveys comprising specimens and questionnaires associated with bacterial enteric diseases, bacterial meningitis, plague, tuberculosis and malaria were sent annually to test participants’ diagnostic proficiency. Identical surveys were sent to referee laboratories for quality control. Materials were prepared, packaged and shipped in accordance with standard protocols. Findings and reports were due within 30 days. Key methodological decisions and test results were categorized as acceptable or unacceptable on the basis of consensus feedback from referees, using established grading schemes. Findings Between 2002 and 2009, participation increased from 30 to 48 Member States of the WHO and from 39 to 78 laboratories. Each survey was returned by 64–93% of participants. Mean turnaround time was 25.9 days. For bacterial enteric diseases and meningitis components, bacterial identification was acceptable in 65% and 69% of challenges, respectively, but serotyping and antibiotic susceptibility testing and reporting were frequently unacceptable. Microscopy was acceptable for 73% of plague challenges. Tuberculosis microscopy was satisfactorily performed, with 87% of responses receiving acceptable scores. In the malaria component, 82% of responses received acceptable scores for species identification but only 51% of parasite quantitation scores were acceptable. Conclusion The external quality assessment programme consistently identified certain functional deficiencies requiring strengthening that were present in African public health microbiology laboratories.

2012-01-01

Background: Exposure of externally programmable shunt-valves (EPS-valves) to magnetic resonance imaging (MRI) may lead to unexpected changes in shunt settings, or affect the ability to reprogram the valve. We undertook this study to examine the effect of exposure to a 3T MRI on a group of widely used EPS-valves. Methods: Evaluations were performed on first generation EPS-valves (those without a locking mechanism to prevent changes in shunt settings by external magnets other than the programmer) and second generation EPS-valves (those with a locking mechanisms). Fifteen new shunt-valves were divided into five groups of three identical valves each, and then exposed to a series of six simulated MRI scans. After each of the exposures, the valves were evaluated to determine if the valve settings had changed, and whether the valves could be reprogrammed. The study produced 18 evaluations for each line of shunt-valves. Results: Exposure of the first generation EPS-valves to a 3T magnetic field resulted in frequent changes in the valve settings; however, all valves retained their ability to be reprogrammed. Repeated exposure of the second generation EPS-valves has no effect on shunt valve settings, and all valves retained their ability to be interrogated and reprogrammed. Conclusions: Second generation EPS-valves with locking mechanisms can be safely exposed to repeated 3T MRI systems, without evidence that shunt settings will change. The exposure of the first generation EPS-valves to 3T MRI results in frequent changes in shunt settings that necessitate re-evaluation soon after MRI to avoid complications. PMID:22937481

Developing and testing an instrument to measure the presence of conditions for successful implementation of quality improvement collaboratives.

In quality improvement collaboratives (QICs) teams of practitioners from different health care organizations are brought together to systematically improve an aspect of patient care. Teams take part in a series of meetings to learn about relevant best practices, quality methods and change ideas, and share experiences in making changes in their own local setting. The purpose of this study was to develop an instrument for measuring team organization, external change agent support and support from the team's home institution in a Dutch national improvement and dissemination programme for hospitals based on several QICs. The exploratory methodological design included two phases: a) content development and assessment, resulting in an instrument with 15 items, and b) field testing (N = 165). Internal consistency reliability was tested via Cronbach's alpha coefficient. Principal component analyses were used to identify underlying constructs. Tests of scaling assumptions according to the multi trait/multi-item matrix, were used to confirm the component structure. Three components were revealed, explaining 65% of the variability. The components were labelled 'organizational support', 'team organization' and 'external change agent support'. One item not meeting item-scale criteria was removed. This resulted in a 14 item instrument. Scale reliability ranged from 0.77 to 0.91. Internal item consistency and divergent validity were satisfactory. On the whole, the instrument appears to be a promising tool for assessing team organization and internal and external support during QIC implementation. The psychometric properties were good and warrant application of the instrument for the evaluation of the national programme and similar improvement programmes.

Perspectives for environment and health research in Horizon 2020: dark ages or golden era?

2014-11-01

The European Commission recently published the first calls for proposals for the Horizon 2020 (H2020) work programme for research and innovation. When browsing through the Health programme, it became apparent that the work programme made little reference to environmental health research. In this commentary we describe major milestones of environmental health research in previous European Framework Programmes and the policy shift that took place when preparing H2020. We introduce mobile health technologies as a niche innovation to reconcile the environmental health research arena with the H2020 programme that has a clear focus on ICT. The recent economic crises urged strong policy action to reinforce Europe's economic and innovation leadership. Market-driven and job-creating ambitions became primary goals of H2020. Environmental health-related keywords referring to, e.g. human biomonitoring, exposure assessment or exposome are absent in the current H2020-calls and this may suggest a lack of opportunities for environmental health researchers. Technologies related to mobile healthcare (mhealth) are rapidly maturing and offer new research and market opportunities. In a typically technology-pushed market, these sensor technologies however require validation by a third-party and implementation in large-scale public health monitoring studies. Also, issues related to data protection need further development to warrant user rights and privacy. If the European environmental health research arena succeeds in embracing these new mhealth sensor technologies, it may not only create an opportunity to play a role as a key innovation partner in health transition technologies, but it may also support authorities to realize a transition in our healthcare with a much bigger emphasis on a preventive and sustainable system.

To examine the relative sensitivity to detect functional mobility changes with a full-length parent questionnaire compared with a computerized adaptive testing version of the questionnaire after a 16-week group fitness programme. Prospective, pre- and posttest study with a 16-week group fitness intervention. Three community-based fitness centres. Convenience sample of children (n = 28) with physical or developmental disabilities. A 16-week group exercise programme held twice a week in a community setting. A full-length (161 items) paper version of a mobility parent questionnaire based on the Pediatric Evaluation of Disability Inventory, but expanded to include expected skills of children up to 15 years old was compared with a 15-item computer adaptive testing version. Both measures were administered at pre- and posttest intervals. Both the full-length Pediatric Evaluation of Disability Inventory and the 15-item computer adaptive testing version detected significant changes between pre- and posttest scores, had large effect sizes, and standardized response means, with a modest decrease in the computer adaptive test as compared with the 161-item paper version. Correlations between the computer adaptive and paper formats across pre- and posttest scores ranged from r = 0.76 to 0.86. Both functional mobility test versions were able to detect positive functional changes at the end of the intervention period. Greater variability in score estimates was generated by the computerized adaptive testing version, which led to a relative reduction in sensitivity as defined by the standardized response mean. Extreme scores were generally more difficult for the computer adaptive format to estimate with as much accuracy as scores in the mid-range of the scale. However, the reduction in accuracy and sensitivity, which did not influence the group effect results in this study, is counterbalanced by the large reduction in testing burden.

To investigate the effects of a predefined mini-trampoline therapy programme for increasing postural control, mobility and the ability to perform activities of daily living after stroke. Randomized non-blinded controlled pilot study. Neurological rehabilitation hospital. First-time stroke; age 18-80 years; independent standing ability for a minimum of 2 minutes. Patients were randomized into two groups: the mini-trampoline group (n = 20) received 10 sessions of balance training using the mini-trampoline over three weeks. The patients of the control group (n =20) participated 10 times in a group balance training also over three weeks. Postural control (Berg Balance Scale, BBS), mobility and gait endurance (timed 'up and go' test, TUG; 6-minute walk test, 6MWT) and the ability to perform activities of daily living (Barthel Index, BI). Measurements were undertaken prior to and after the intervention period. Both groups were comparable before the study. The mini-trampoline group improved significantly more in the BBS (P = 0.003) compared to the control group. Mean or median differences of both groups showed improvements in the TUG 10.12 seconds/7.23 seconds, the 6MWT 135 m/75 m and the BI 20 points/13 points for the mini-trampoline and control group, respectively. These outcome measurements did not differ significantly between the two groups. A predefined mini-trampoline training programme resulted in significantly increased postural control in stroke patients compared to balance training in a group. Although not statistically significant, the mini-trampoline training group showed increased improvement in mobility and activities of daily living. These differences could have been statistically significant if we had investigated more patients (i.e. a total sample of 84 patients for the TUG, 98 patients for the 6MWT, and 186 patients for the BI).

Device Data Protection in Mobile Healthcare Applications

Weerasinghe, Dasun; Rajarajan, Muttukrishnan; Rakocevic, Veselin

The rapid growth in mobile technology makes the delivery of healthcare data and services on mobile phones a reality. However, the healthcare data is very sensitive and has to be protected against unauthorized access. While most of the development work on security of mobile healthcare today focuses on the data encryption and secure authentication in remote servers, protection of data on the mobile device itself has gained very little attention. This paper analyses the requirements and the architecture for a secure mobile capsule, specially designed to protect the data that is already on the device. The capsule is a downloadable software agent with additional functionalities to enable secure external communication with healthcare service providers, network operators and other relevant communication parties.

[Health promotion and wellness programs in private corporate organizations. Problems of trans-national and trans-cultural transferability].

Health promotion and wellness programmes in corporate organisations are subjects of considerable interest to both the providers (companies) and the consumers (employees). Economic considerations constitute a significant factor in businesses' interest in adopting health promotion programmes and in the wellness communities attempts to sell such programming to business. Substantial elements of both the business and wellness communities believe that health promotion programmes are financially profitable in addition to, and as a result of, improving employee's health. A fact which has not yet attracted significant research activities is a comparative analysis of corporate health promotion and wellness programmes in different societies with different cultural backgrounds, corporate cultures and external environments. Especially the emerging of a "New Europe" after the full realisation of the Common Market (EC) after 1992 and the tremendous economic possibilities after substantial political changes in the political structure of the eastern part of Europe (on its way to capitalism) might make it worth to look into corporate wellness programs of European organisations and to discuss pros and cons after comparing them with the ones of their American counterparts. Most important facts in which US organisations differ from most European corporations are not only the internal corporate culture but also the external environment, such as direct government interventions and political pressure from the consumer interest groups (strong unions). In many European countries the government imposes a very tight regulatory and legal framework and dictates the way corporate organisations have to share the burden of health related costs and have to provide occupational, wellness or preventive programmes for their employees.(ABSTRACT TRUNCATED AT 250 WORDS)

Donors and other development partners commonly introduce innovative practices and technologies to improve health in low and middle income countries. Yet many innovations that are effective in improving health and survival are slow to be translated into policy and implemented at scale. Understanding the factors influencing scale-up is important. We conducted a qualitative study involving 150 semi-structured interviews with government, development partners, civil society organisations and externally funded implementers, professional associations and academic institutions in 2012/13 to explore scale-up of innovative interventions targeting mothers and newborns in Ethiopia, the Indian state of Uttar Pradesh and the six states of northeast Nigeria, which are settings with high burdens of maternal and neonatal mortality. Interviews were analysed using a common analytic framework developed for cross-country comparison and themes were coded using Nvivo. We found that programme implementers across the three settings require multiple steps to catalyse scale-up. Advocating for government to adopt and finance health innovations requires: designing scalable innovations; embedding scale-up in programme design and allocating time and resources; building implementer capacity to catalyse scale-up; adopting effective approaches to advocacy; presenting strong evidence to support government decision making; involving government in programme design; invoking policy champions and networks; strengthening harmonisation among external programmes; aligning innovations with health systems and priorities. Other steps include: supporting government to develop policies and programmes and strengthening health systems and staff; promoting community uptake by involving media, community leaders, mobilisation teams and role models. We conclude that scale-up has no magic bullet solution - implementers must embrace multiple activities, and require substantial support from donors and governments in doing so.

Stempliuk, Valeska; Ramon-Pardo, Pilar; Holder, Reynaldo

2014-01-01

Core components Health care-associated infections (HAIs) are a major cause of morbidity and mortality. In addition to pain and suffering, HAIs increase the cost of health care and generates indirect costs from loss of productivity for patients and society as a whole. Since 2005, the Pan American Health Organization has provided support to countries for the assessment of their capacities in infection prevention and control (IPC). More than 130 hospitals in 18 countries were found to have poor IPC programmes. However, in the midst of many competing health priorities, IPC programmes are not high on the agenda of ministries of health, and the sustainability of national programmes is not viewed as a key point in making health care systems more consistent and trustworthy. Comprehensive IPC programmes will enable countries to reduce the mobility, mortality and cost of HAIs and improve quality of care. This paper addresses the relevance of national infection prevention and control (NIPC) programmes in promoting, supporting and reinforcing IPC interventions at the level of hospitals. A strong commitment from national health authorities in support of national IPC programmes is crucial to obtaining a steady decrease of HAIs, lowering health costs due to HAIs and ensuring safer care.

Murray, Ian

2004-06-01

This article outlines the development of the family health nurse (FNH) programme, which was delivered by the University of Stirling in the highlands and islands of Scotland as part of a World Health Organization European pilot project. An outline of the structure of the programme and its key features is described. The concept of the FHN emerged from the WHO's initiative to develop a practitioner who has the family as the organizing focus of their practice (WHO, 2000). An insight is provided into the experience of the first students to undergo this programme, along with a brief summary of the main findings of the external evaluation of both the education programme and the implementation of the role in the remote and rural communities of the highlands and islands of Scotland. Suggestions are made that will hopefully influence the second phase of this project that the Scottish Executive are supporting in an urban setting, which is due to begin in September 2004.

The purpose of this study was to explore the audits, quality assurance (QA) programmes and legal frameworks used in selected abattoirs in Zimbabwe and slaughterhouse workers' perceptions on their effectiveness. Data on slaughterhouse workers was gathered through a self-completed questionnaire and additional information was obtained from slaughterhouse and government records. External auditing was conducted mainly by the Department of Veterinary Public Health with little contribution from third parties. Internal auditing was restricted to export abattoirs. The checklist used on auditing lacked objective assessment criteria and respondents cited several faults in the current audit system. Most respondents (> 50.0%) knew the purposes and benefits of audit and QA inspections. All export abattoirs had QA programmes such as hazard analysis critical control point and ISO 9001 (a standard used to certify businesses' quality management systems) but their implementation varied from minimal to nil. The main regulatory defect observed was lack of requirements for a QA programme. Audit and quality assurance communications to the selected abattoirs revealed a variety of non-compliances with most respondents revealing that corrective actions to audit (84.3%) and quality assurance (92.3%) shortfalls were not done. A high percentage of respondents indicated that training on quality (76.8%) and regulations (69.8%) was critical. Thus, it is imperative that these abattoirs develop a food safety management system comprising of QA programmes, a microbial assessment scheme, regulatory compliance, standard operating procedures, internal and external auditing and training of workers.

Background The relationship between mobility, violence and mental health has largely been unexplored in developing countries. This study screens for signs of major depression, and assesses its association with mobility and violence among female sex workers (FSWs) in southern India. Methods Data (N=2400) for this study were used from a cross-sectional Behavioral Tracking Survey (BTS-2014) conducted among FSWs from a southern state of India as part of the Avahan programme. Major depression of FSWs was assessed using the Patient Health Questionnaire-2 depression scale. Descriptive statistics, frequency, bivariate, interaction effect and multivariate logistic regression techniques were used for the analysis. Results More than one-fourth of FSWs (29%) screened positive for major depression. The likelihood of screening positive for major depression was 6 times higher among FSWs who were both mobile for sex work outside their district of residence and had experienced any violence (combined association) during the past 1 year (62% vs 19%, adjusted OR 6.1, 95% CI 4.4 to 8.6) compared with those who reported neither. The individual association results show that FSWs who reported being mobile outside the district, and FSWs who were beaten or raped in the past 1 year, were 3 times more likely to screen positive for major depression. Conclusions The findings indicate that violence and mobility are independently associated with major depression among FSWs. The combined association of mobility and violence poses a greater risk to the mental health of FSWs than their independent association. These results point to the need for creating an enabling environment for FSWs to enhance existing efforts to reduce the spread of HIV and mental health problems. The study highlights that HIV prevention efforts among FSWs in India require evidence-based research and integrated programme approaches to address mental health issues. PMID:27612536

Teaching smartphone and microcontroller systems using "Android Java"

Tigrek, Seyitriza

Mobile devices are becoming indispensable tools for many students and educators. Mobile technology is starting a new era in the computing methodologies in many engineering disciplines and laboratories. Microcontroller extension that communicates with mobile devices will take the data acquisition and control process into a new level in the sensing technology and communication. The purpose of this thesis is to develop a framework to incorporate the new mobile platform with robust embedded systems into the engineering curriculum. For this purpose a course material is developed "Introduction to Programming Java on a Mobile Platform" to teach novice programmers how to create applications, specifically on Android. Combining an introductory level programming class with the Android platform can appeal to non-programming individuals in multiple disciplines. The proposed course curriculum reduces the learning time, and allows senior engineering students to use the new framework for their specific needs in the labs such as mobile data acquisition and control projects. This work provides techniques for instructors with modest programming background to teach cutting edge technology, which is smartphone programming. Techniques developed in this work minimize unnecessary information carried into current teaching approaches with hands-on practice. It also helps the students with minimal background requirements overcome the barriers that have evolved around computer programming. The motivation of this thesis is to create a tailored programming introductory course to teach Java programming on Android by incorporating selected efficient methods from extant literature. The mechanism proposed in this thesis is to keep students motivated by an active approach based on student-centered learning with collaborative work. Teamwork through pair programming is adapted in this teaching process. Bloom's taxonomy, along with a knowledge survey, is used as a guide to classify the information and exercise problems. A prototype curriculum is a deliverable of this research that is suitable for novice programmers-such as engineering freshmen students. It also contains advanced material that allows senior students to use mobile phone and a microcontroller system to enhance engineering laboratories.

Falls are a common cause of injury in older adults, with the prevention of falls being a priority for public health departments around the world. This study investigated the feasibility, and impact of an 8 week contemporary dance programme on modifiable physical (physical activity status, mobility, sedentary behaviour patterns) and psychosocial (depressive state, fear of falling) risk factors for falls. An uncontrolled 'pre-post' intervention design was used. Three groups of older (60 yrs.+) adults were recruited from local community groups to participate in a 3 separate, 8 week dance programmes. Each programme comprised two, 90 min dance classes per week. Quantitative measures of physical activity, sedentary behaviour, depression, mobility and fear of falling were measured at baseline (T1) and after 8 weeks of dance (T2). Weekly attendance was noted, and post-study qualitative work was conducted with participants in 3 separate focus groups. A combined thematic analysis of these data was conducted. Of the 38 (Mean Age = 77.3 ± 8.4 yrs., 37 females) who attended the dance sessions, 22 (21 females; 1 male; mean age = 74.8, ±8.44) consented to be part of the study. Mean attendance was 14.6 (±2.6) sessions, and mean adherence was 84.3% (±17). Significant increases in moderate and vigorous physical activity were noted, with a significant decrease in sitting time over the weekdays (p < 0.05). Statistically significant decreases in the mean Geriatric Depression Scale (p < 0.05) and fear of falling (p < 0.005) score were noted, and the time taken to complete the TUG test decreased significantly from 10.1 s to 7.7 s over the 8 weeks (p < 0.005). Themes from the focus groups included the dance programme as a means of being active, health Benefits, and dance-related barriers and facilitators. The recruitment of older adults, good adherence and favourability across all three sites indicate that a dance programme is feasible as an intervention, but this may be limited to females only. Contemporary dance has the potential to positively affect the physical activity, sitting behaviour, falls related efficacy, mobility and incidence of depression in older females which could reduce their incidence of falls. An adequately powered study with control groups are required to test this intervention further.

A Nordic-Soviet programme was initiated in 1990 to evaluate the external and internal radiation exposure of the inhabitants of several villages in the Bryansk region of Russia. This area was one of the number of areas particularly affected by the nuclear accident at the Chernobyl Nuclear Power Plant in 1986. Measurements were carried out yearly until 1998 and after that more irregularly; in 2000, 2006 and 2008 respectively. The effective dose estimates were based on individual thermoluminescent dosemeters and on in vivo measurements of the whole body content of (137)Cs (and (134)Cs during the first years of the programme). The decrease in total effective dose during the almost 2 decade follow-up was due to a continuous decrease in the dominating external exposure and a less decreasing but highly variable exposure from internal irradiation. In 2008, the observed average effective dose (i.e. the sum of external and internal exposure) from Chernobyl (137)Cs to the residents was estimated to be 0.3mSv y(-1). This corresponds to 8% of the estimated annual dose in 1990 and to 1% of the estimated annual dose in 1986. As a mean for the population group and for the period of the present study (2006-2008), the average yearly effective dose from Chernobyl cesium was comparable to the absorbed dose obtained annually from external exposure to cosmic radiation plus internal exposure to naturally occurring radionuclides in the human body. Our data indicate that the effective dose from internal exposure is becoming increasingly important as the body burdens of Chernobyl (137)Cs are decreasing more slowly than the external exposure. However, over the years there have been large individual variations in both the external and internal effective doses, as well as differences between the villages investigated. These variations and differences are presented and discussed in this paper. Copyright © 2011 Elsevier B.V. All rights reserved.

A methodological approach to identify external factors for indicator-based risk adjustment illustrated by a cataract surgery register

PubMed Central

2014-01-01

Background Risk adjustment is crucial for comparison of outcome in medical care. Knowledge of the external factors that impact measured outcome but that cannot be influenced by the physician is a prerequisite for this adjustment. To date, a universal and reproducible method for identification of the relevant external factors has not been published. The selection of external factors in current quality assurance programmes is mainly based on expert opinion. We propose and demonstrate a methodology for identification of external factors requiring risk adjustment of outcome indicators and we apply it to a cataract surgery register. Methods Defined test criteria to determine the relevance for risk adjustment are “clinical relevance” and “statistical significance”. Clinical relevance of the association is presumed when observed success rates of the indicator in the presence and absence of the external factor exceed a pre-specified range of 10%. Statistical significance of the association between the external factor and outcome indicators is assessed by univariate stratification and multivariate logistic regression adjustment. The cataract surgery register was set up as part of a German multi-centre register trial for out-patient cataract surgery in three high-volume surgical sites. A total of 14,924 patient follow-ups have been documented since 2005. Eight external factors potentially relevant for risk adjustment were related to the outcome indicators “refractive accuracy” and “visual rehabilitation” 2–5 weeks after surgery. Results The clinical relevance criterion confirmed 2 (“refractive accuracy”) and 5 (“visual rehabilitation”) external factors. The significance criterion was verified in two ways. Univariate and multivariate analyses revealed almost identical external factors: 4 were related to “refractive accuracy” and 7 (6) to “visual rehabilitation”. Two (“refractive accuracy”) and 5 (“visual rehabilitation”) factors conformed to both criteria and were therefore relevant for risk adjustment. Conclusion In a practical application, the proposed method to identify relevant external factors for risk adjustment for comparison of outcome in healthcare proved to be feasible and comprehensive. The method can also be adapted to other quality assurance programmes. However, the cut-off score for clinical relevance needs to be individually assessed when applying the proposed method to other indications or indicators. PMID:24965949

Antimicrobial resistance in Neisseria gonorrhoeae is monitored in the European Union/European Economic Area through the European Gonococcal Antimicrobial Surveillance Programme (Euro-GASP) coordinated by the European Centre for Disease Prevention and Control. Euro-GASP includes a sentinel surveillance programme which aims to detect in a timely manner changes in resistance patterns and inform treatment guidelines. The programme aims to test a representative number of isolates from each European Union/European Economic Area member state per year for a range of therapeutically relevant antimicrobials through a biannual hybrid centralised/decentralised system. Testing is supported by an External Quality Assurance programme and a laboratory training programme. Participation in the programme has increased to 21 countries in 2012. Euro-GASP has been able to detect the rapid spread of isolates with decreased susceptibility to cefixime across Europe in 2010 and 2011. Results from the programme have informed changes in European treatment guidelines for gonorrhoea and led to the development of the 'Response plan to control and manage the threat of multidrug resistant gonorrhoea in Europe'. Future challenges for Euro-GASP include supporting countries to participate in Euro-GASP through decentralised testing, improving timeliness and epidemiological data quality, and increasing participation from Eastern Europe.

Strain-effect transistors: Theoretical study on the effects of external strain on III-nitride high-electron-mobility transistors on flexible substrates

Shervin, Shahab; Asadirad, Mojtaba; Materials Science and Engineering Program, University of Houston, Houston, Texas 77204

This paper presents strain-effect transistors (SETs) based on flexible III-nitride high-electron-mobility transistors (HEMTs) through theoretical calculations. We show that the electronic band structures of InAlGaN/GaN thin-film heterostructures on flexible substrates can be modified by external bending with a high degree of freedom using polarization properties of the polar semiconductor materials. Transfer characteristics of the HEMT devices, including threshold voltage and transconductance, are controlled by varied external strain. Equilibrium 2-dimensional electron gas (2DEG) is enhanced with applied tensile strain by bending the flexible structure with the concave-side down (bend-down condition). 2DEG density is reduced and eventually depleted with increasing compressive strainmore » in bend-up conditions. The operation mode of different HEMT structures changes from depletion- to enchantment-mode or vice versa depending on the type and magnitude of external strain. The results suggest that the operation modes and transfer characteristics of HEMTs can be engineered with an optimum external bending strain applied in the device structure, which is expected to be beneficial for both radio frequency and switching applications. In addition, we show that drain currents of transistors based on flexible InAlGaN/GaN can be modulated only by external strain without applying electric field in the gate. The channel conductivity modulation that is obtained by only external strain proposes an extended functional device, gate-free SETs, which can be used in electro-mechanical applications.« less

Effects of Magnetic Nanoparticles and External Magnetostatic Field on the Bulk Heterojunction Polymer Solar Cells

DOE PAGES

Wang, Kai; Yi, Chao; Liu, Chang; ...

2015-03-18

The price of energy to separate tightly bound electron-hole pair (or charge-transfer state) and extract freely movable charges from low-mobility materials represents fundamental losses for many low-cost photovoltaic devices. In bulk heterojunction (BHJ) polymer solar cells (PSCs), approximately 50% of the total efficiency lost among all energy loss pathways is due to the photogenerated charge carrier recombination within PSCs and low charge carrier mobility of disordered organic materials. To address these issues, we introduce magnetic nanoparticles (MNPs) and orientate these MNPS within BHJ composite by an external magnetostatic field. Over 50% enhanced efficiency was observed from BHJ PSCs incorporated withmore » MNPs and an external magnetostatic field alignment when compared to the control BHJ PSCs. The optimization of BHJ thin film morphology, suppression of charge carrier recombination, and enhancement in charge carrier collection result in a greatly increased short-circuit current density and fill factor, as a result, enhanced power conversion efficiency.« less

The voluntary phase of an industry-led national Bovine Viral Diarrhoea (BVD) eradication programme began in Ireland on January 1, 2012 with the goal of progressing to a compulsory programme in 2013. The development and implementation of the programme in 2012 was informed by a review of current and prior eradication programmes elsewhere in Europe and extensive stakeholder consultation. The programme was based on tissue tag testing of newborn calves in participating herds, with the status of the mothers of calves with positive or inconclusive results requiring clarification. Participating herd owners were required to comply with a series of guidelines, including not selling cattle suspected of being persistently infected. For herds compliant with the guidelines, the results from 2012 counted as one of three years of tag testing anticipated in the compulsory phase of the programme. Testing was carried out in laboratories designated for this purpose by the cross-industry BVD Implementation Group that oversees the programme. Results were reported to a central database managed by the Irish Cattle Breeding Federation, and the majority of results were reported to farmers' mobile telephones by SMS message. A detailed review of the programme was conducted, encompassing the period between January 1, 2012 and July 15, 2012, based on results from approximately 500,000 calves. This paper describes the establishment and structure of the programme, and the outcomes of the review, including findings at herd and animal level.

Participation in external quality control (EQC) programmes is recommended by various scientific societies. Results from an EQC programme for embryology laboratories are presented. This 5-year programme consisted of the annual delivery of (i) materials to test toxicity and (ii) a DVD/CD-ROM with images of zygotes and embryos on days 2 and 3, on the basis of which the participants were asked to judge the embryo quality and to take a clinical decision. A high degree of agreement was considered achieved when over 75% of the laboratories produced similar classifications. With respect to the materials analysed, the specificity was 68% and the sensitivity was 83%. Concerning embryo classification, the proportion of embryos on which a high degree of agreement was achieved increased during this period from 35% to 55%. No improvement was observed in the degree of agreement on the clinical decision to be taken. Day-3 embryos produced a higher degree of agreement (58%) than did day-2 embryos (32%) (P<0.05). Participation in EQC increased the degree of inter-laboratory agreement on embryo classification, but not the corresponding agreement on clinical decision taking. It is necessary to introduce measures aimed at standardizing decision taking procedures in embryology laboratories. Copyright (c) 2009 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

Background Demographic information is foundational for the planning and management of social programmes, in particular health services. The existing INDEPTH network surveillance sites are limited to coverage of sedentary populations. Including mobile populations in this approach would be expensive, time consuming and possibly low in accuracy. Very little is known about the demography of mobile pastoralists and their animals, so innovative approaches are urgently needed. Objective To test and evaluate a mobile demographic surveillance system for mobile pastoralist households, including livestock herds, using mobile phones. Design Mobile pastoralist camps were monitored (10 for 12 months and 10 for 18 months) using biweekly mobile phone calls with camp leaders and their wives to conduct interviews about the households and livestock. The collected information was validated through personal visits, GPS data and a livestock demographic model.

Demographic information is foundational for the planning and management of social programmes, in particular health services. The existing INDEPTH network surveillance sites are limited to coverage of sedentary populations. Including mobile populations in this approach would be expensive, time consuming and possibly low in accuracy. Very little is known about the demography of mobile pastoralists and their animals, so innovative approaches are urgently needed. To test and evaluate a mobile demographic surveillance system for mobile pastoralist households, including livestock herds, using mobile phones. Mobile pastoralist camps were monitored (10 for 12 months and 10 for 18 months) using biweekly mobile phone calls with camp leaders and their wives to conduct interviews about the households and livestock. The collected information was validated through personal visits, GPS data and a livestock demographic model. The study showed the feasibility of mobile phone surveillance for mobile pastoralist camps, providing usable, valid information on human and livestock population structures, pregnancy outcomes and herd dynamics, as well as migration patterns. The approach was low-cost and applicable with the existing local resources. Demographic surveillance in mobile populations is feasible using mobile phones. Expansion of the small-scale system into a full mobile demographic surveillance system is warranted and would likely lead to improved planning and provision of human and animal health care.

SU-C-BRF-05: Design and Geometric Validation of An Externally and Internally Deformable, Programmable Lung Motion Phantom

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cheung, Y; Sawant, A

Purpose: Most clinically-deployed strategies for respiratory motion management in lung radiotherapy (e.g., gating, tracking) use external markers that serve as surrogates for tumor motion. However, typical lung phantoms used to validate these strategies are rigid-exterior+rigid-interior or rigid-exterior+deformable-interior. Neither class adequately represents the human anatomy, which is deformable internally as well as externally. We describe the construction and experimental validation of a more realistic, externally- and internally-deformable, programmable lung phantom. Methods: The outer shell of a commercially-available lung phantom (RS- 1500, RSD Inc.) was used. The shell consists of a chest cavity with a flexible anterior surface, and embedded vertebrae, rib-cagemore » and sternum. A 3-axis platform was programmed with sinusoidal and six patient-recorded lung tumor trajectories. The platform was used to drive a rigid foam ‘diaphragm’ that compressed/decompressed the phantom interior. Experimental characterization comprised of mapping the superior-inferior (SI) and anterior-posterior (AP) trajectories of external and internal radioopaque markers with kV x-ray fluoroscopy and correlating these with optical surface monitoring using the in-room VisionRT system. Results: The phantom correctly reproduced the programmed motion as well as realistic effects such as hysteresis. The reproducibility of marker trajectories over multiple runs for sinusoidal as well as patient traces, as characterized by fluoroscopy, was within 0.4 mm RMS error for internal as well as external markers. The motion trajectories of internal and external markers as measured by fluoroscopy were found to be highly correlated (R=0.97). Furthermore, motion trajectories of arbitrary points on the deforming phantom surface, as recorded by the VisionRT system also showed a high correlation with respect to the fluoroscopically-measured trajectories of internal markers (R=0.92). Conclusion: We have developed a realistic externally- and internally-deformable lung phantom that will serve as a valuable tool for clinical QA and motion management research.

Disclosed is a method and system for performing operations on at least one input data vector in order to produce at least one output vector to permit easy, scalable and fast programming of a petascale equivalent supercomputer. A PetaFlops Router may comprise one or more PetaFlops Nodes, which may be connected to each other and/or external data provider/consumers via a programmable crossbar switch external to the PetaFlops Node. Each PetaFlops Node has a FPGA and a programmable intra-FPGA crossbar switch that permits input and output variables to be configurably connected to various physical operators contained in the FPGA as desired by a user. This allows a user to specify the instruction set of the system on a per-application basis. Further, the intra-FPGA crossbar switch permits the output of one operation to be delivered as an input to a second operation. By configuring the external crossbar switch, the output of a first operation on a first PetaFlops Node may be used as the input for a second operation on a second PetaFlops Node. An embodiment may provide an ability for the system to recognize and generate pipelined functions. Streaming operators may be connected together at run-time and appropriately staged to allow data to flow through a series of functions. This allows the system to provide high throughput and parallelism when possible. The PetaFlops Router may implement the user desired instructions by appropriately configuring the intra-FPGA crossbar switch on each PetaFlops Node and the external crossbar switch.

External dosimetry audits give confidence in the safe and accurate delivery of radiotherapy. The RTTQA group have performed an on-site audit programme for trial recruiting centres, who have recently implemented static or rotational IMRT, and those with major changes to planning or delivery systems. Measurements of reference beam output were performed by the host centre, and by the auditor using independent equipment. Verification of clinical plans was performed using the ArcCheck helical diode array. A total of 54 measurement sessions were performed between May 2014 and June 2016 at 28 UK institutions, reflecting the different combinations of planning and delivery systems used at each institution. Average ratio of measured output between auditor and host was 1.002±0.006. Average point dose agreement for clinical plans was -0.3±1.8%. Average (and 95% lower confidence intervals) of gamma pass rates at 2%/2mm, 3%/2mm and 3%/3mm respectively were: 92% (80%), 96% (90%) and 98% (94%). Moderately significant differences were seen between fixed gantry angle and rotational IMRT, and between combination of planning systems and linac manufacturer, but not between anatomical treatment site or beam energy. An external audit programme has been implemented for universal and efficient credentialing of IMRT treatments in clinical trials. Good agreement was found between measured and expected doses, with few outliers, leading to a simple table of optimal and mandatory tolerances for approval of dosimetry audit results. Feedback was given to some centres leading to improved clinical practice. Copyright © 2017 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd. All rights reserved.

2012-08-01

A number of cloud based visual development tools have emerged that provide methods for developing mobile applications quickly and without previous programming experience. The MY NASA DATA (MND) team would like to begin a discussion on how we can best leverage current mobile app technologies and available Earth science datasets. The MY NASA DATA team is developing an approach based on two main ideas. The first is to teach our constituents how to create mobile applications that interact with NASA datasets; the second is to provide web services or Application Programming Interfaces (APIs) that create sources of data that educators, students and scientists can use in their own mobile app development. This framework allows data providers to foster mobile application development and interaction while not becoming a software clearing house. MY NASA DATA's research has included meetings with local data providers, educators, libraries and individuals. A high level of interest has been identified from initial discussions and interviews. This overt interest combined with the marked popularity of mobile applications in our societies has created a new channel for outreach and communications with and between the science and educational communities.

Between August 2012 and April 2013 the Career Development Fellowship programme of the Special Programme for Research and Training in Tropical Diseases (World Health Organization) underwent an external evaluation to assess its past performance and determine recommendations for future programme development and continuous performance improvement. The programme provides a year-long training experience for qualified researchers from low and middle income countries at pharmaceutical companies or product development partnerships. Independent evaluators from the Swiss Tropical and Public Health Institute and the Barcelona Institute for Global Health used a results-based methodology to review the programme. Data were gathered through document review, surveys, and interviews with a range of programme participants. The final evaluation report found the Career Development Fellowship to be relevant to organizers' and programme objectives, efficient in its operations, and effective in its training scheme, which was found to address needs and gaps for both fellows and their home institutions. Evaluators found that the programme has the potential for impact and sustainability beyond the programme period, especially with the successful reintegration of fellows into their home institutions, through which newly-developed skills can be shared at the institutional level. Recommendations included the development of a scheme to support the re-integration of fellows into their home institutions post-fellowship and to seek partnerships to facilitate the scaling-up of the programme. The impact of the Professional Membership Scheme, an online professional development tool launched through the programme, beyond the scope of the Career Development Fellowship programme itself to other applications, has been identified as a positive unintended outcome. The results of this evaluation may be of interest for other efforts in the field of research capacity strengthening in LMICs or, generally, to other professional development schemes of a similar structure.

To compare the clinical effectiveness of a programme of physiotherapy and occupational therapy with standard care in care home residents who have mobility limitations and are dependent in performing activities of daily living. Cluster randomised controlled trial, with random allocation at the level of care home. Care homes within the NHS South Birmingham primary care trust and the NHS Birmingham East and North primary care trust that had more than five beds and provided for people in the care categories "physical disability" and "older people." Care home residents with mobility limitations, limitations in activities of daily living (as screened by the Barthel index), and not receiving end of life care were eligible to take part in the study. A targeted three month occupational therapy and physiotherapy programme. Scores on the Barthel index and the Rivermead mobility index. 24 of 77 nursing and residential homes that catered for residents with mobility limitations and dependency for activities of daily living were selected for study: 12 were randomly allocated to the intervention arm (128 residents, mean age 86 years) and 12 to the control arm (121 residents, mean age 84 years). Participants were evaluated by independent assessors blind to study arm allocation before randomisation (0 months), three months after randomisation (at the end of the treatment period for patients who received the intervention), and again at six months after randomisation. After adjusting for home effect and baseline characteristics, no significant differences were found in mean Barthel index scores at six months post-randomisation between treatment arms (mean effect 0.08, 95% confidence interval -1.14 to 1.30; P=0.90), across assessments (-0.01, -0.63 to 0.60; P=0.96), or in the interaction between assessment and intervention (0.42, -0.48 to 1.32; P=0.36). Similarly, no significant differences were found in the mean Rivermead mobility index scores between treatment arms (0.62, -0.51 to 1.76; P=0.28), across assessments (-0.15, -0.65 to 0.35; P=0.55), or interaction (0.71, -0.02 to 1.44; P=0.06). The three month occupational therapy and physiotherapy programme had no significant effect on mobility and independence. On the other hand, the variation in residents' functional ability, the prevalence of cognitive impairment, and the prevalence of depression were considerably higher in this sample than expected on the basis of previous work. Further research to clarify the efficacy of occupational therapy and physiotherapy is required if access to therapy services is to be recommended in this population. ISRCTN79859980.

Background The main purpose of the present study was to examine the 2-year longitudinal and reciprocal relationship between job mobility and health and burnout. A second aim was to elucidate the effects of perceived organizational justice and turnover intentions on the relationship between job mobility (non-, internally and externally mobile), and health (SF-36) and burnout (CBI). Methods The study used questionnaire data from 662 Swedish civil servants and the data were analysed with Structural Equation Modeling statistical methods. Results The results showed that job mobility was a better predictor of health and burnout, than health and burnout were as predictors of job mobility. The predictive effects were most obvious for psychosocial health and burnout, but negligible as far as physical health was concerned. Organizational justice was found to have a direct impact on health, but not on job mobility; whereas turnover intentions had a direct effect on job mobility. Conclusion The predictive relationship between job mobility and health has practical implications for health promotive actions in different organizations. PMID:18489747

We assessed the impact of global health initiatives (GHIs) on the health care system of Angola, as a contribution to documenting how GHIs, such as the Global Fund, GAVI and PEPFAR, influence the planning and delivery of health services in low-income countries and how national systems respond. We collected the views of national and sub-national key informants through 42 semi-structured interviews between April 2009 and May 2011 (12 at the national level and 30 at the sub-national level). We used a snowball technique to identify respondents from government, donors and non-governmental organisations. GHIs stimulated the formulation of a health policy and of plans and strategies, but the country has yet to decide on its priorities for health. At the regional level, managers lack knowledge of how GHIs' function, but they assess the effects of external funds as positive as they increased training opportunities, and augment the number of workers engaged in HIV or other specific disease programmes. However, GHIs did not address the challenge of attraction and retention of qualified personnel in provinces. Since Angola is not entirely dependent on external funding, national strategic programmes and the interventions of GHIs co-habit well, in contrast to countries such as Mozambique, which heavily depend on external aid.

An externally and internally deformable, programmable lung motion phantom

Cheung, Yam; Sawant, Amit, E-mail: amit.sawant@utsouthwestern.edu

Purpose: Most clinically deployed strategies for respiratory motion management in lung radiotherapy (e.g., gating and tracking) use external markers that serve as surrogates for tumor motion. However, typical lung phantoms used to validate these strategies are based on a rigid exterior and a rigid or a deformable-interior. Such designs do not adequately represent respiration because the thoracic anatomy deforms internally as well as externally. In order to create a closer approximation of respiratory motion, the authors describe the construction and experimental testing of an externally as well as internally deformable, programmable lung phantom. Methods: The outer shell of a commerciallymore » available lung phantom (RS-1500, RSD, Inc.) was used. The shell consists of a chest cavity with a flexible anterior surface, and embedded vertebrae, rib-cage and sternum. A custom-made insert was designed using a piece of natural latex foam block. A motion platform was programmed with sinusoidal and ten patient-recorded lung tumor trajectories. The platform was used to drive a rigid foam “diaphragm” that compressed/decompressed the phantom interior. Experimental characterization comprised of determining the reproducibility and the external–internal correlation of external and internal marker trajectories extracted from kV x-ray fluoroscopy. Experiments were conducted to illustrate three example applications of the phantom—(i) validating the geometric accuracy of the VisionRT surface photogrammetry system; (ii) validating an image registration tool, NiftyReg; and (iii) quantifying the geometric error due to irregular motion in four-dimensional computed tomography (4DCT). Results: The phantom correctly reproduced sinusoidal and patient-derived motion, as well as realistic respiratory motion-related effects such as hysteresis. The reproducibility of marker trajectories over multiple runs for sinusoidal as well as patient traces, as characterized by fluoroscopy, was within 0.25 mm RMS error. The motion trajectories of internal and external radio-opaque markers as measured by fluoroscopy were found to be highly correlated (R > 0.95). Using the phantom, it was demonstrated that the motion trajectories of regions-of-interest on the surface as measured by VisionRT are highly consistent with corresponding fluoroscopically acquired surface marker trajectories, with RMS errors within 0.26 mm. Furthermore, it was shown that the trajectories of external and internal marker trajectories derived from NiftyReg deformation vector fields were within 1 mm root mean square errors comparing to trajectories obtained by segmenting markers from individual fluoro frames. Finally, it was shown that while 4DCT can be used to localize internal markers for sinusoidal motion with reasonable accuracy, the localization error increases significantly (by a factor of ∼2) in the presence of cycle-to-cycle variations that are observed in patient-derived respiratory motion. Conclusions: The authors have developed a realistic externally and internally deformable, programmable lung phantom that will serve as a valuable tool for clinical and investigational motion management studies in thoracic and abdominal radiation therapies.« less

Context Aware Programmable Trackers for the Next Generation Internet

NASA Astrophysics Data System (ADS)

Sousa, Pedro

This work introduces and proposes the concept of context aware programmable trackers for the next generation Internet. The proposed solution gives ground for the development of advanced applications based on the P2P paradigm and will foster collaborative efforts among several network entities (e.g. P2P applications and ISPs). The proposed concept of context aware programmable trackers allows that several peer selection strategies might be supported by a P2P tracker entity able to improve the peer selection decisions according with pre-defined objectives and external inputs provided by specific services. The flexible, adaptive and enhanced peer selection semantics that might be achieved by the proposed solution will contribute for devising novel P2P based services and business models for the future Internet.

The Pacific region has widely dispersed populations, limited financial and human resources and a high burden of disease. There is an urgent need to improve the availability, reliability and timeliness of useable health data. The purpose of this paper is to share lessons learnt from a three-year pilot field epidemiology training programme that was designed to respond to these Pacific health challenges. The pilot programme built on and further developed an existing field epidemiology training programme for Pacific health staff. The programme was delivered in country by epidemiologists working for Pacific Public Health Surveillance Network partners. The programme consisted of five courses: four one-week classroom-based courses and one field epidemiology project. Sessions were structured so that theoretical understanding was achieved through interaction and reinforced through practical hands-on group activities, case studies and other interactive practical learning methods. As of September 2016, 258 students had commenced the programme. Twenty-six course workshops were delivered and one cohort of students had completed the full five-course programme. The programme proved popular and gained a high level of student engagement. Face-to-face delivery, a low student-to-facilitator ratio, substantial group work and practical exercises were identified as key factors that contributed to the students developing skills and confidence. Close engagement of leaders and the need to quickly evaluate and adapt the curriculum were important lessons, and the collaboration between external partners was considered important for promoting a harmonized approach to health needs in the Pacific.

An Optimal Method for Detecting Internal and External Intrusion in MANET

NASA Astrophysics Data System (ADS)

Rafsanjani, Marjan Kuchaki; Aliahmadipour, Laya; Javidi, Mohammad M.

Mobile Ad hoc Network (MANET) is formed by a set of mobile hosts which communicate among themselves through radio waves. The hosts establish infrastructure and cooperate to forward data in a multi-hop fashion without a central administration. Due to their communication type and resources constraint, MANETs are vulnerable to diverse types of attacks and intrusions. In this paper, we proposed a method for prevention internal intruder and detection external intruder by using game theory in mobile ad hoc network. One optimal solution for reducing the resource consumption of detection external intruder is to elect a leader for each cluster to provide intrusion service to other nodes in the its cluster, we call this mode moderate mode. Moderate mode is only suitable when the probability of attack is low. Once the probability of attack is high, victim nodes should launch their own IDS to detect and thwart intrusions and we call robust mode. In this paper leader should not be malicious or selfish node and must detect external intrusion in its cluster with minimum cost. Our proposed method has three steps: the first step building trust relationship between nodes and estimation trust value for each node to prevent internal intrusion. In the second step we propose an optimal method for leader election by using trust value; and in the third step, finding the threshold value for notifying the victim node to launch its IDS once the probability of attack exceeds that value. In first and third step we apply Bayesian game theory. Our method due to using game theory, trust value and honest leader can effectively improve the network security, performance and reduce resource consumption.

Besides an improvement in quality of life, one of the major targets of rehabilitation programmes is to preserve the ability to work and to integrate the patient into working life again. Cancer in particular is often associated with a loss of employment and joblessness, frequently caused by incomplete rehabilitation. The programme is aimed at young cancer patients aged between 18 and 40 years. In addition to medical rehabilitation, they undergo a specially developed programme which they complete in groups of no more than 5 persons. At baseline and at the end of the 3 weeks rehabilitation, tests on physical and mental capacity are conducted. During rehabilitation, different training programmes concerning mobility at work, fine motor skills and cognitive abilities are held, complemented by an intensive psycho-social training programme. Additionally, patients receive individual social counselling. So far, 34 patients with an average age of 31.8 years have participated in the programme, 65% of them suffering from malignant haematological diseases. The combination of a medical and a vocational rehabilitation programme was judged extremely positively by the participants, which remained the case 6 months after completion of the programme. The rehabilitation programme significantly reduced work incapacity periods: at baseline, only 6% of the participants had not experienced such periods, but after 3 and 6 months, this rate had increased to 61% and 62% respectively. This was accompanied by an increased health-related quality of life and reduced fatigue. With our pilot project we were able to show that such a programme is feasible, can be well integrated into clinical routine and is successful.

Treatment of immobilization hypercalciuria using weekly alendronate in two quadriplegic patients.

Metabolic and urinary problems encountered in spinal cord injury patients are multifaced. We report two patients with high-level spinal cord injuries who have developed hypercalciuria after admission to the rehabilitation unit. To establish a clean intermittent self-catheterization programme, the hypercalciuria was treated successfully with alendronate. Twenty-four-hour urinary calcium excretion decreased significantly after medical treatment for hypercalciuria. Since high-level quadriplegic patients may not be mobilized in the acute phase of the rehabilitation, use of alendronate for preventing hypercalciuria and maintaining a successful clean intermittent self-catheterization programme can be considered as a supportive/complementary measure.

This is essential given the ongoing and rapidly changing nature of mobile device technologies. An integral principle and significant constraint upon forensic practitioners is that of forensic soundness. Our adversary model specifically considers and integrates the constraints of forensic soundness on the adversary, in our case, a forensic practitioner. One construction of the adversary model is an evidence collection and analysis methodology for Android devices. Using the methodology with six popular cloud apps, we were successful in extracting various information of forensic interest in both the external and internal storage of the mobile device.

The benefit of external, often industry-based, speakers for a seminar series associated with both undergraduate and graduate programmes is relatively unchallenged. However, the means by which such a seminar series can be encapsulated within a structured learning module, and the appropriate design of an accompanying assessment methodology, is not so obvious. This paper examines how such a learning module can be formulated and addresses the main issues involved in the design of such a module, namely the selection of speakers, format of seminars, method of delivery and assessment methodology, informed by the objectives of the module.

Meandering Brownian Donkeys

NASA Astrophysics Data System (ADS)

Eichhorn, R.; Reimann, P.

2004-04-01

We consider a Brownian particle whose motion is confined to a ``meandering'' pathway and which is driven away from thermal equilibrium by an alternating external force. This system exhibits absolute negative mobility, i.e. when an external static force is applied the particle moves in the direction opposite to that force. We reveal the physical mechanism behind this ``donkey-like'' behavior, and derive analytical approximations that are in excellent agreement with numerical results.

Destabilising automobility? The emergent mobilities of generation Y.

PubMed

Hopkins, Debbie

2017-04-01

This paper uses empirical material gathered with young adults in New Zealand to examine a potential sustainability transition-in-practice. It draws from two frameworks; the actor-centred Energy Cultures Framework to explore mobility behaviours, and the multi-level perspective (MLP) to situate behaviour change within the socio-technical transitions literature. The MLP has traditionally been used to analyse historical transitions (e.g. from the horse and cart to the motor vehicle), but in this paper, it is used to explore an on-going change trend; the emergent mobilities of young adults who appear to be aspiring for different types of mobility. A series of mobility trends are described, which emerged from a programme of qualitative interviews (n = 51). The material culture, norms and practices that constitute these trends are articulated. These are then considered through the lens of the MLP. The evidence points to emergent trends of multimodality that, if leveraged upon and supported, could contribute to a systemic sustainability transition.

To compare the effects of exergames (EGs) using the Xbox Kinect™ device and home exercise (HE) on balance, functional mobility, and quality of life of individuals aged 65 years or older. One hundred participants who met the inclusion criteria were randomized to the EG or HE group. The EG group took part in a 6-week programme using the Xbox360Kinect™ device, and the HE group took part in a 6-week balance exercise programme at home 5 days a week. The Berg Balance Scale (BBS) was used to assess balance, the Timed Up and Go (TUG) test was used to evaluate functional walking, and the Short Form 36 (SF-36) was used to assess quality of life. Forty-eight participants in the EG group and 42 participants in the HE group completed the study. The groups were similar in terms of age, sex, and pretreatment values of BBS, TUG, and SF-36. Although the BBS scores of both groups improved significantly (all p<0.05), the post-treatment scores of the EG group were better than those of the HE group. The TUG scores improved only in the EG group (p<0.05). The increase in the BBS scores and decrease in the TUG test scores were significant only in the EG group (all p<0.05). A significant improvement was also observed in the quality of life parameters of physical functioning, social role functioning, physical role restriction, general health perceptions, and physical component scores in the post-exercise evaluations of the EG group. The participants commented that they found the EG programme very entertaining. The EG can be considered a safe, entertaining and sustainable alternative to HE programmes, and it may have positive effects on balance, functional walking and quality of life in geriatric subjects.

The relationship between mobility, violence and mental health has largely been unexplored in developing countries. This study screens for signs of major depression, and assesses its association with mobility and violence among female sex workers (FSWs) in southern India. Data (N=2400) for this study were used from a cross-sectional Behavioral Tracking Survey (BTS-2014) conducted among FSWs from a southern state of India as part of the Avahan programme. Major depression of FSWs was assessed using the Patient Health Questionnaire-2 depression scale. Descriptive statistics, frequency, bivariate, interaction effect and multivariate logistic regression techniques were used for the analysis. More than one-fourth of FSWs (29%) screened positive for major depression. The likelihood of screening positive for major depression was 6 times higher among FSWs who were both mobile for sex work outside their district of residence and had experienced any violence (combined association) during the past 1 year (62% vs 19%, adjusted OR 6.1, 95% CI 4.4 to 8.6) compared with those who reported neither. The individual association results show that FSWs who reported being mobile outside the district, and FSWs who were beaten or raped in the past 1 year, were 3 times more likely to screen positive for major depression. The findings indicate that violence and mobility are independently associated with major depression among FSWs. The combined association of mobility and violence poses a greater risk to the mental health of FSWs than their independent association. These results point to the need for creating an enabling environment for FSWs to enhance existing efforts to reduce the spread of HIV and mental health problems. The study highlights that HIV prevention efforts among FSWs in India require evidence-based research and integrated programme approaches to address mental health issues.

Trusted Operations on Sensor Data †

PubMed Central

Joosen, Wouter; Michiels, Sam; Hughes, Danny

2018-01-01

The widespread use of mobile devices has allowed the development of participatory sensing systems that capture various types of data using the existing or external sensors attached to mobile devices. Gathering data from such anonymous sources requires a mechanism to establish the integrity of sensor readings. In many cases, sensor data need to be preprocessed on the device itself before being uploaded to the target server while ensuring the chain of trust from capture to the delivery of the data. This can be achieved by a framework that provides a means to implement arbitrary operations to be performed on trusted sensor data, while guaranteeing the security and integrity of the data. This paper presents the design and implementation of a framework that allows the capture of trusted sensor data from both external and internal sensors on a mobile phone along with the development of trusted operations on sensor data while providing a mechanism for performing predefined operations on the data such that the chain of trust is maintained. The evaluation shows that the proposed system ensures the security and integrity of sensor data with minimal performance overhead. PMID:29702601

Abdad, Mohammad Yazid; Squires, Raynal C; Cognat, Sebastien; Oxenford, Christopher John

2017-01-01

Arboviruses continue to pose serious public health threats in the World Health Organization (WHO) Western Pacific Region. As such, laboratories need to be equipped for their accurate detection. In 2011, to ensure test proficiency, the WHO Regional Office for the Western Pacific piloted an external quality assessment (EQA) programme for arbovirus diagnostics. By 2016, it had grown into a global programme with participation of 96 laboratories worldwide, including 25 laboratories from 19 countries, territories and areas in the Region. The test performance of the 25 laboratories in the Region in 2016 was high with 23 (92%) reporting correct results in all specimens for dengue and chikungunya viruses. For Zika virus, 18 (72%) of the 25 laboratories reported correct results in all specimens, while seven (28%) demonstrated at least one error. When comparing iterations of this EQA programme in the Region between 2013 and 2016, the number of participating laboratories increased from 18 to 25. The first round only included dengue virus, while the latest round additionally included chikungunya, Zika and yellow fever viruses. Proficiency for molecular detection of dengue virus remained high (83–94%) over the four-year period. The observed proficiency for arbovirus diagnostics between 2013 and 2016 is an indicator of laboratory quality improvement in the Region. PMID:29051839

To assess both the feasibility and value of conducting an external quality assurance programme concerning technical aspects of cytopathology laboratory practice, and the interest by laboratories in enrolling in such a programme. Six technical surveys, comprising staining exercises and questionnaires relating to laboratory practice, were distributed over a 4-year period to the approximately 220 laboratories enrolled in the RCPAQAP Cytopathology slide survey modules. Staining exercises using the Papanicolaou and Romanowsky techniques, the preparation of urine and body fluid specimens and immunocytochemistry on the cell block material were assessed. Accompanying relevant questionnaires were included, and one survey comprised a questionnaire alone concerning the collection of urinary tract and body fluid samples. Provision of an external cytopathology technical module was feasible for the RCPAQAP and participation rates (maximum of 87% per survey; average 68% for stained slides and 66% for questionnaires) were commendable, particularly considering these were optional undertakings with some exercises not applicable to all laboratories. The great majority of submitted slides were scored as satisfactory, and there was an especially high standard for the immunocytochemical staining exercise with 95% considered satisfactory, including 50.6% with a perfect score. Reasons for suboptimal scores were provided for potential quality improvement for interested laboratories. A wealth of information relating to laboratory practice was provided to the RCPAQAP which was collated and summarised for laboratory use. The provision of a technical module in cytopathology is both a feasible and valuable undertaking of interest to laboratories which should become standard practice for cytopathology external quality assurance providers. © 2016 John Wiley & Sons Ltd.

Somers, Thomas

2017-08-01

This article addresses the inclusion of immigrant minority language students in Content and Language Integrated Learning (CLIL) bilingual education programmes. It reviews results of research on (1) the reasons, beliefs and attitudes underlying immigrant minority language parents' and students' choice for CLIL programmes; (2) these students' proficiency in the languages of instruction and their academic achievement; and (3) the effects of first language typology on their second and third language proficiency. The author explores conditions and reasons for the effectiveness of CLIL pedagogy, as well as the comparative suitability of CLIL programmes for immigrant minority language students. The review shows that CLIL programmes provide a means to acquire important linguistic, economic and symbolic capital in order to effect upward social mobility. Findings demonstrate that immigrant minority language students enrolled in CLIL programmes are able to develop equal or superior levels of proficiency in both languages of instruction compared to majority language students; with previous development of first language literacy positively impacting academic language development. CLIL programmes are found to offer immigrant minority language students educational opportunities and effective pedagogical support which existing mainstream monolingual and minority bilingual education programmes may not always be able to provide. In light of these findings, the author discusses shortcomings in current educational policy. The article concludes with recommendations for further research.[Figure not available: see fulltext.

Restoring integrity--A grounded theory of coping with a fast track surgery programme.

Jørgensen, Lene Bastrup; Fridlund, Bengt

2016-01-01

The aim of this study was to generate a theory conceptualizing and explaining behavioural processes involved in coping in order to identify the predominant coping types and coping type-specific features. Patients undergoing fast track procedures do not experience a higher risk of complications, readmission, or mortality. However, such programmes presuppose an increasing degree of patient involvement, placing high educational, physical, and mental demands on the patients. There is a lack of knowledge about how patients understand and cope with fast track programmes. The study design used classical grounded theory. The study used a multimodal approach with qualitative and quantitative data sets from 14 patients. Four predominant types of coping, with distinct physiological, cognitive, affective, and psychosocial features, existed among patients going through a fast track total hip replacement programme. These patients' main concern was to restore their physical and psychosocial integrity, which had been compromised by reduced function and mobility in daily life. To restore integrity they economized their mental resources, while striving to fulfil the expectations of the fast track programme. This goal was achieved by being mentally proactive and physically active. Three out of the four predominant types of coping matched the expectations expressed in the fast track programme. The non-matching behaviour was seen among the most nervous patients, who claimed the right to diverge from the programme. In theory, four predominant types of coping with distinct physiological, cognitive, affective, and psychosocial features occur among patients going through a fast track total hip arthroplasty programme.

Adults with haemophilia and other bleeding disorders often develop lower limb musculoskeletal problems associated with bleeds into joints and muscles, which may affect balance performance and increase likelihood of falling. The aim of this study was to evaluate the effectiveness of an individualized balance and strength home exercise programme on improving balance and related outcomes for adults with haemophilia and other bleeding disorders. Twenty male adults with haemophilia and other bleeding disorders (mean age 39.4 years, 95% CI = 33.7-45.1) were recruited to participate. They underwent a comprehensive clinical and force platform assessment of balance and related measures. Based on assessment findings, the assessing physiotherapist provided an individualized home exercise programme of balance, strengthening and walking exercises. Re-assessment occurred after the 4-month exercise programme. Twelve participants (60%) completed the programme and were re-assessed. There were no safety problems or dropouts associated with the exercise programme aggravating joint status. Although there were no statistically significant changes in any of the measures (adjusted for multiple comparisons), there were improvements of between 5% and 22% on 10 of the 16 measures, with the Neurocom modified Clinical Test of Sensory Interaction on Balance (P = 0.036) and Timed Sit to Stand (P = 0.064) approaching significance. A tailored home exercise programme targeting balance, strengthening and walking is feasible for adults with haemophilia and other bleeding disorders. These results suggest that positive physical outcomes including improved balance and mobility may be achieved with this type of programme.

Emerging models for mobilizing family support for chronic disease management: a structured review.

We identify recent models for programmes aiming to increase effective family support for chronic illness management and self-care among adult patients without significant physical or cognitive disabilities. We then summarize evidence regarding the efficacy for each model identified. Structured review of studies published in medical and psychology databases from 1990 to the present, reference review, general Web searches and conversations with family intervention experts. Review was limited to studies on conditions that require ongoing self-management, such as diabetes, chronic heart disease and rheumatologic disease. Programmes with three separate foci were identified: (1) Programmes that guide family members in setting goals for supporting patient self-care behaviours have led to improved implementation of family support roles, but have mixed success improving patient outcomes. (2) Programmes that train family in supportive communication techniques, such as prompting patient coping techniques or use of autonomy supportive statements, have successfully improved patient symptom management and health behaviours. (3) Programmes that give families tools and infrastructure to assist in monitoring clinical symptoms and medications are being conducted, with no evidence to date on their impact on patient outcomes. The next generation of programmes to improve family support for chronic disease management incorporate a variety of strategies. Future research can define optimal clinical situations for family support programmes, the most effective combinations of support strategies, and how best to integrate family support programmes into comprehensive models of chronic disease care.

The state of ergonomics for mobile computing technology.

PubMed

Dennerlein, Jack T

2015-01-01

Because mobile computing technologies, such as notebook computers, smart mobile phones, and tablet computers afford users many different configurations through their intended mobility, there is concern about their effects on musculoskeletal pain and a need for usage recommendations. Therefore the main goal of this paper to determine which best practices surrounding the use of mobile computing devices can be gleaned from current field and laboratory studies of mobile computing devices. An expert review was completed. Field studies have documented various user configurations, which often include non-neutral postures, that users adopt when using mobile technology, along with some evidence suggesting that longer duration of use is associated with more discomfort. It is therefore prudent for users to take advantage of their mobility and not get stuck in any given posture for too long. The use of accessories such as appropriate cases or riser stands, as well as external keyboards and pointing devices, can also improve postures and comfort. Overall, the state of ergonomics for mobile technology is a work in progress and there are more research questions to be addressed.

Problematic mobile phone use of Swiss adolescents: is it linked with mental health or behaviour?

2016-04-01

To investigate the associations between problematic mobile phone use and mental health and behavioural problems in 412 Swiss adolescents owning a mobile phone while controlling for amount of mobile phone use. Problematic mobile phone use was determined by the MPPUS-10 (Mobile Phone Problem Use Scale) and related to health and behavioural problems by means of multivariable regression modelling. MPPUS-10 was 4.7 (95 % CI 1.8, 7.6) units higher in girls than in boys, increased significantly with age and was significantly decreased with increasing educational level of the parents. Furthermore, problematic mobile phone use was associated with impaired psychological well-being, impaired parent and school relationships and more behavioural problems but was not related to peer support and social acceptance. Our study indicates that problematic mobile phone use is associated with external factors such as worse home and school environment and internal factors such as impaired mental health and behavioural problems of the adolescents and thus problematic mobile phone use should be addressed, in particular when dealing with adolescents showing behavioural or emotional problems.

The aim of this study was to develop a competency based training programme to support multidisciplinary working in a combined biochemistry and haematology laboratory. The training programme was developed to document that staff were trained in the full range of laboratory tests that they were expected to perform. This programme subsequently formed the basis for the annual performance review of all staff. All staff successfully completed the first phase of the programme. This allowed laboratory staff to work unsupervised at night as part of a partial shift system. All staff are now working towards achieving a level of competence equivalent to the training level required for state registration by the Council for Professions Supplementary to Medicine. External evaluation of the training programme has included accreditation by the Council for Professions Supplementary to Medicine and reinspection by Clinical Pathology Accreditation (UK) Ltd. The development of a competency based training system has facilitated the introduction of multidisciplinary working in the laboratory. In addition, it enables the documentation of all staff to ensure that they are fully trained and are keeping up to date, because the continuing professional development programme in use in our laboratory has been linked to this training scheme. This approach to documentation of training facilitated a recent reinspection by Clinical Pathology Accreditation (UK) Ltd.

This research examined the processes underpinning changes in psychological well-being and behavioural regulation in cardiac rehabilitation (CR) patients using self-determination theory (SDT). A repeated measures design was used to identify the longitudinal relationships between SDT variables, psychological well-being and exercise behaviour during and following a structured CR programme. Participants were 389 cardiac patients (aged 36-84 years; M(age) = 64 ± 9 years; 34.3% female) referred to a 12-week-supervised CR programme. Psychological need satisfaction, behavioural regulation, health-related quality of life, physical self-worth, anxiety and depression were measured at programme entry, exit and six month post-programme. During the programme, increases in autonomy satisfaction predicted positive changes in behavioural regulation, and improvements in competence and relatedness satisfaction predicted improvements in behavioural regulation and well-being. Competence satisfaction also positively predicted habitual physical activity. Decreases in external regulation and increases in intrinsic motivation predicted improvements in physical self-worth and physical well-being, respectively. Significant longitudinal relationships were identified whereby changes during the programme predicted changes in habitual physical activity and the mental quality of life from exit to six month follow-up. Findings provide insight into the factors explaining psychological changes seen during CR. They highlight the importance of increasing patients' perceptions of psychological need satisfaction and self-determined motivation to improve well-being during the structured component of a CR programme and longer term physical activity.

Awareness among people of reproductive age about the factors that influence fertility and reproductive outcomes, including medically assisted reproduction outcomes, is generally low. To improve awareness about the potentially modifiable factors that affect fertility and reproductive outcomes, 'Your Fertility', a fertility health promotion programme funded by the Australian Government, was established in 2011. This paper describes the development and evaluation of the reach of the Your Fertility programme from its inception in 2011 to June 2016. Systematically recorded outcomes for the programme's key focus areas and Google Analytics data were collated. Key achievements include developing and maintaining an internationally renowned website that experiences high growth and demand for fertility-related information; by 2016, over 5 million users had viewed more than 10 million webpages, and over 96,000 users had engaged in programme messages across social media. Programme messages have reached more than 4 million Australian social media users, and a potential audience of 150 million through media coverage across more than 320 media features. More than 4200 education and health professionals have completed online learning modules, and external partnerships have been established with 14 separate organizations. Data collected over 5 years indicate that the Your Fertility programme meets a need for targeted, evidence-based, accessible fertility-related information.

We propose a framework for the systematic analysis of mobile phone data to identify relevant mobility profiles in a population. The proposed framework allows finding distinct human mobility profiles based on the digital trace of mobile phone users characterized by a Matrix of Individual Trajectories (IT-Matrix). This matrix gathers a consistent and regularized description of individual trajectories that enables multi-scale representations along time and space, which can be used to extract aggregated indicators such as a dynamic multi-scale population count. Unsupervised clustering of individual trajectories generates mobility profiles (clusters of similar individual trajectories) which characterize relevant group behaviors preserving optimal aggregation levels for detailed and privacy-secured mobility characterization. The application of the proposed framework is illustrated by analyzing fully anonymized data on human mobility from mobile phones in Senegal at the arrondissement level over a calendar year. The analysis of monthly mobility patterns at the livelihood zone resolution resulted in the discovery and characterization of seasonal mobility profiles related with economic activities, agricultural calendars and rainfalls. The use of these mobility profiles could support the timely identification of mobility changes in vulnerable populations in response to external shocks (such as natural disasters, civil conflicts or sudden increases of food prices) to monitor food security.

The radioisotope techniques used in molecular and cellular biology involve external and internal irradiation risk. The personal dosemeter may be a reasonable indicator for external irradiation. However, it is necessary to control the possible internal contamination associated with the development of these techniques. The aim of this project is to analyse the most usual techniques and to establish programmes of internal monitoring for specific radionuclides (32P, 35S, 14C, 3H, 125I and 131I). To elaborate these programmes it was necessary to analyse the radioisotope techniques. Two models have been applied (NRPB and IAEA) to the more significant techniques, according to the physical and chemical nature of the radionuclides, their potential importance in occupational exposure and the possible injury to the genetic material of the cell. The results allowed the identification of the techniques with possible risk of internal contamination. It was necessary to identify groups of workers that require individual monitoring. The risk groups have been established among the professionals exposed, according to different parameters: the general characteristics of receptor, the radionuclides used (the same user can work with one, two or three radionuclides at the same time) and the results of the models applied. Also a control group was established. The study of possible intakes in these groups has been made by urinalysis and whole-body counter. The theoretical results are coherent with the experimental results. They have allowed guidance to individual monitoring to be proposed. Basically, the document shows: (1) the analysis of the radiosotopic techniques, taking into account the special containment equipment; (2) the establishment of the need of individual monitoring; and (3) the required frequency of measurements in a routine programme.

2010-10-01

Brain-computer interfaces (BCIs) offer tremendous promise for improving the quality of life for disabled individuals. BCIs use spike sorting to identify the source of each neural firing. To date, spike sorting has been performed by either using off-chip analysis, which requires a wired connection penetrating the skull to a bulky external power/processing unit, or via custom application-specific integrated circuits that lack the programmability to perform different algorithms and upgrades. In this research, we propose and test the feasibility of performing on-chip, real-time spike sorting on a programmable smartdust, including feature extraction, classification, compression, and wireless transmission. A detailed power/performance tradeoff analysis using DVFS is presented. Our experimental results show that the execution time and power density meet the requirements to perform real-time spike sorting and wireless transmission on a single neural channel.

2016-02-01

This study shows the use of SWOT to analyse students' perceptions of an environmental education joint master's programme in order to determine if it runs as originally planned. The open answers given by students highlight the inter-university nature of the master's, the technological innovation used as major points, and the weaknesses in the management coordination or the duplicate contents as minor points. The external analysis is closely linked with the students' future jobs, their labour opportunities available to them after graduation. The innovative treatment of the data is exportable to the evaluation of programmes of other degrees because it allows the description linked to its characteristics and its design through the students' point of view.

Problem The Pacific region has widely dispersed populations, limited financial and human resources and a high burden of disease. There is an urgent need to improve the availability, reliability and timeliness of useable health data. Context The purpose of this paper is to share lessons learnt from a three-year pilot field epidemiology training programme that was designed to respond to these Pacific health challenges. The pilot programme built on and further developed an existing field epidemiology training programme for Pacific health staff. Action The programme was delivered in country by epidemiologists working for Pacific Public Health Surveillance Network partners. The programme consisted of five courses: four one-week classroom-based courses and one field epidemiology project. Sessions were structured so that theoretical understanding was achieved through interaction and reinforced through practical hands-on group activities, case studies and other interactive practical learning methods. Outcome As of September 2016, 258 students had commenced the programme. Twenty-six course workshops were delivered and one cohort of students had completed the full five-course programme. The programme proved popular and gained a high level of student engagement. Discussion Face-to-face delivery, a low student-to-facilitator ratio, substantial group work and practical exercises were identified as key factors that contributed to the students developing skills and confidence. Close engagement of leaders and the need to quickly evaluate and adapt the curriculum were important lessons, and the collaboration between external partners was considered important for promoting a harmonized approach to health needs in the Pacific.

Nurse manager succession planning: A cost-benefit analysis.

PubMed

Phillips, Tracy; Evans, Jennifer L; Tooley, Stephanie; Shirey, Maria R

2018-03-01

This commentary presents a cost-benefit analysis to advocate for the use of succession planning to mitigate the problems ensuing from nurse manager turnover. An estimated 75% of nurse managers will leave the workforce by 2020. Many benefits are associated with proactively identifying and developing internal candidates. Fewer than 7% of health care organisations have implemented formal leadership succession planning programmes. A cost-benefit analysis of a formal succession-planning programme from one hospital illustrates the benefits of the programme in their organisation and can be replicated easily. Assumptions of nursing manager succession planning cost-benefit analysis are identified and discussed. The succession planning exemplar demonstrates the integration of cost-benefit analysis principles. Comparing the costs of a formal nurse manager succession planning strategy with the status quo results in a positive cost-benefit ratio. The implementation of a formal nurse manager succession planning programme effectively reduces replacement costs and time to transition into the new role. This programme provides an internal pipeline of future leaders who will be more successful than external candidates. Using an actual cost-benefit analysis equips nurse managers with valuable evidence depicting succession planning as a viable business strategy. © 2017 John Wiley & Sons Ltd.

Deshmukh, Anita Arvind; Deshmukh, Raghvendra B.

2016-12-01

This paper presents the design of a Programmable Asynchronous Modulator (PAM) with field control of resolution and power. A novel variable hysteresis Schmitt Trigger (ST) is used for external programmability. Asynchronous Sigma-Delta Modulator (ASDM) implementation with external control voltages is proposed to supervise the resolution and power. This architecture with reduced circuit complexity considerably improves the earlier realizations by eliminating multiple current sources as well switched capacitor circuits and results in power saving up to 87 %. Proposed PAM design demonstrates an improved SNDR of 115 dB, DR of 96 dB, and power consumption below 280 μW. It illustrates Effective Number of Bits (ENOB) to 18.81 and Figure of Merit (FoM) to 0.15 fJ/conversion step. Modulator is implemented in Cadence UMC Hspice 0.18 μm CMOS analog technology. Off-chip PAM control for resolution/power performance has potential applications in battery operated ultra low power applications like IoT; where ADC is one of the major power consuming components. It offers the promise for an efficient performance with power saving.

Space Technology for Medical Aids

Under one of the earliest contracts awarded in the Apollo lunar landing program, Parker Hannifin Corporation developed and produced equipment for controlling the flow of propellants into the mammoth engines of the Saturn moonbooster. Today, Parker is supplying the huge valves that control propellant flow from the Space Shuttle's external fuel tank to the engines of the Shuttle Orbiter as well as the "peanut valve," named for its small size. In 1977, NASA, recognizing the company's special expertise in miniature systems, asked Parker to participate in the development of an implantable artificial sphincter for control of urinary incontinence. The company's peanut valve experience provided an ideal base for a new biomedical project, the Programmable Implantable Medication System (PIMS) for continuous, computer-directed delivery of precisely metered medication -- insulin, for example -- within a patient's body. The work on PIMS also inspired development of Micromed, a related programmable medication device for external, rather than implantable use. The Biomedical Products Division has also applied its fluid handling expertise to a drugless therapy system called Cryomax for the treatment of such disorders as rheumatoid arthritis and lupus.

Background Social media and mobile applications that allow people to work anywhere are changing the way people can contribute and collaborate. Objective We sought to determine the feasibility of using mobile workforce technology to validate the locations of automated external defibrillators (AEDs), an emergency public health resource. Methods We piloted the use of a mobile workforce application, to verify the location of 40 AEDs in Philadelphia county. AEDs were pre-identified in public locations for baseline data. The task of locating AEDs was posted online for a mobile workforce from October 2011 to January 2012. Participants were required to submit a mobile phone photo of AEDs and descriptions of the location. Results Thirty-five of the 40 AEDs were identified within the study period. Most, 91% (32/35) of the submitted AED photo information was confirmed project baseline data. Participants also provided additional data such as business hours and other nearby AEDs. Conclusions It is feasible to engage a mobile workforce to complete health research-related tasks. Participants were able to validate information about emergency public health resources.

Normal biomechanics of the ankle joint includes sagittal as well as axial rotation. Current understanding of mobile-bearing motion at the tibial-polyethylene interface in total ankle arthroplasty (TAA) is limited to anterior-posterior (AP) motion of the polyethylene component. The purpose of our study was to define the motion of the polyethylene component in relation to the tibial component in a mobile-bearing TAA in both the sagittal and axial planes in postoperative patients. Patients who were a minimum of 12 months postoperative from a third-generation mobile-bearing TAA were identified. AP images were saved at maximum internal and external rotation, and the lateral images were saved in maximum plantarflexion and dorsiflexion. Sagittal range of motion and AP translation of the polyethylene component were measured from the lateral images. Axial rotation was determined by measuring the relative position of the 2 wires within the polyethylene component on AP internal and external rotation imaging. This relationship was compared to a table developed from fluoroscopic images taken at standardized degrees of axial rotation of a nonimplanted polyethylene with the associated length relationship of the 2 imbedded wires. Sixteen patients were included in this investigation, 9 (56%) were male and average age was 68 (range, 49-80) years. Time from surgery averaged 25 (range, 12-38) months. Total sagittal range of motion averaged 23±9 (range, 9-33) degrees. Axial motion for total internal and external rotation of the polyethylene component on the tibial component averaged 6±5 (range, 0-18) degrees. AP translation of the polyethylene component relative to the tibial component averaged 1±1 (range, 0-3) mm. There was no relationship between axial rotation or AP translation of the polyethylene component and ankle joint range of motion (P > .05). To our knowledge, this is the first investigation to measure axial and sagittal motion of the polyethylene component at the tibial implant interface in patients following a mobile-bearing TAA. Based on outcome scores and range-of-motion measurements, we believe the patients in this study are a representative cross section of subjects compared to other TAA research results. The results from this investigation indicate the potential for a mobile-bearing TAA to fall within the parameters of normal polyaxial ankle motion. The multiplanar articulation in a mobile-bearing TAA may reduce excessively high peak pressures during the complex dynamic tibial and talar motion, which may have a positive influence on gait pattern, polyethylene wear, and implant longevity.

International development programmes, including global health interventions, have the capacity to make important implicit and explicit benefits to diplomatic and international relations outcomes. Conversely, in the absence of awareness of these implications, such programmes may generate associated threats. Due to heightened international tensions in conflict and post-conflict settings, greater attention to diplomatic outcomes may therefore be necessary. We examine related 'collateral' effects of Global Fund-supported tuberculosis programmes in Iraq. During site visits to Iraq conducted during 2012 and 2013 on behalf of the Global Fund to Fight AIDS, Tuberculosis and Malaria, on-site service delivery evaluations, unstructured interviews with clinical and operational staff, and programme documentary review of Global Fund-supported tuberculosis treatment and care programmes were conducted. During this process, a range of possible external or collateral international relations and diplomatic effects of global health programmes were assessed according to predetermined criteria. A range of positive diplomatic and international relations effects of Global Fund-supported programmes were observed in the Iraq setting. These included (1) geo-strategic accessibility and coverage; (2) provisions for programme sustainability and alignment; (3) contributions to nation-building and peace-keeping initiatives; (4) consistent observation of social, cultural and religious norms in intervention selection; and (5) selection of the most effective and cost-effective tuberculosis treatment and care interventions. Investments in global health programmes have valuable diplomatic, as well as health-related, outcomes, associated with their potential to prevent, mitigate or reverse international tension and hostility in conflict and post-conflict settings, provided that they adhere to appropriate criteria. The associated international presence in such regions may also contribute to peace-keeping efforts. Global health programmes may frequently produce a wider range of 'collateral benefits' that conventional monitoring and evaluation systems should be expanded to assess, in keeping with contemporary efforts to leverage development programmes from a 'global health diplomacy' perspective.

Breaking Out of the Lab: Measuring Real-Time Responses to Televised Political Content in Real-World Settings.

Real-time response (RTR) measurement is an important technique for analyzing human processing of electronic media stimuli. Although it has been demonstrated that RTR data are reliable and internally valid, some argue that they lack external validity. The reason for this is that RTR measurement is restricted to a laboratory environment due to its technical requirements. This paper introduces a smartphone app that 1) captures real-time responses using the dial technique and 2) provides a solution for one of the most important problems in RTR measurement, the (automatic) synchronization of RTR data. In addition, it explores the reliability and validity of mobile RTR measurement by comparing the real-time reactions of two samples of young and well-educated voters to the 2013 German televised debate. Whereas the first sample participated in a classical laboratory study, the second sample was equipped with our mobile RTR system and watched the debate at home. Results indicate that the mobile RTR system yields similar results to the lab-based RTR measurement, providing evidence that laboratory studies using RTR are externally valid. In particular, the argument that the artificial reception situation creates artificial results has to be questioned. In addition, we conclude that RTR measurement outside the lab is possible. Hence, mobile RTR opens the door for large-scale studies to better understand the processing and impact of electronic media content.

Five billion people worldwide do not have timely access to surgical care. Cinterandes is one of the only mobile surgical units in low- and middle-income countries. This paper examines the methodology that Cinterandes uses to deliver mobile surgery. Founding and core staff were interviewed, four missions were participated in, and internal documents and records were analysed between 1 May and 1 July 2014. Cinterandes performed 7641 operations over the last 20 years (60% gastrointestinal/laparoscopic), travelling 300,000 km to remote areas of Ecuador. The mobile surgery programme was initiated by a local Ecuadorian surgeon in 1980. Funding was acquired from businesses, private hospitals, and individuals, to fund a low-cost surgical truck, simple equipment, and running costs. The mobile surgical unit is a 24-foot modified Isuzu truck containing a preparation room with general equipment storage and running water, together with an operating room including the operating table, anaesthetic and surgical equipment. Mission structure includes: patient identification by a network of local medical personnel in remote regions; pre-operative assessment at 1 week by core team via teleconsultations; four-day surgical missions; post-operative recovery in tents or a local clinic; post-operative follow-up care by local personnel and remote teleconsultations. The permanent core team includes seven members; lead surgeon, lead anaesthetist, operating-room technician, medical coordinator, driver, general coordinator, and receptionist. Additional support members include seven regular surgeons, residents, medical students, and volunteers. Surgery is a very effective way to gain the trust of the community, due to immediate results. Trust opens doors to other programmes (e.g. family medicine). Surgery can be incorporated with all other aspects of health care, which can in turn be incorporated with all other aspects of human development, education, food production and nutrition, housing, work and productivity, communication, and recreation.

Test the programme's generalisability-external validity in a different context. A randomised controlled trial (n=508) of English-speaking callers from smoking-discordant households (≥1 smoker and ≥1 non-smoker). 2-1-1 Texas/United Way HELPLINE call specialists serving the Texas Gulf Coast recruited callers and delivered three mailings and one coaching call, supported by an online tracking system. Data collectors, blind to study assignment, conducted telephone interviews 3 and 6 months postbaseline. At 3 months, more intervention households reported a smoke-free home (46.6% vs 25.4%, p<0.0001; growth model intent-to-treat OR=1.48, 95% CI 1.241 to 1.772, p<0.0001). At 6 months, self-reported full bans were 62.9% for intervention participants and 38.4% for controls (OR=2.19). Texas trial participants were predominantly women (83%), single-smoker households (76%) and African-American (65%); half had incomes ≤US$10 000/year (50%). Texas recruitment was <50% of the other sites. Fewer callers reported having a smoker in the household. Almost twice the callers with a household smoker declined interest in the programme/study. Our findings in a region with lower smoking rates and more diverse callers, including English-speaking Latinos, support programme generalisability and convey evidence of external validity.

Capillary-Physics Mechanism of Elastic-Wave Mobilization of Residual Oil

NASA Astrophysics Data System (ADS)

Beresnev, I. A.; Pennington, W. D.; Turpening, R. M.

2003-12-01

Much attention has been given to the possibility of vibratory mobilization of residual oil as a method of enhanced recovery. The common features of the relevant applications have nonetheless been inconsistency in the results of field tests and the lack of understanding of a physical mechanism that would explain variable experiences. Such a mechanism can be found in the physics of capillary trapping of oil ganglia, driven through the pore channels by an external pressure gradient. Entrapping of ganglia occurs due to the capillary pressure building on the downstream meniscus entering a narrow pore throat. The resulting internal-pressure imbalance acts against the external gradient, which needs to exceed a certain threshold to carry the ganglion through. The ganglion flow thus exhibits the properties of the Bingham (yield-stress) flow, not the Darcy flow. The application of vibrations is equivalent to the addition of an oscillatory forcing to the constant gradient. When this extra forcing acts along the gradient, an instant "unplugging" occurs, while, when the vibration reverses direction, the flow is plugged. This asymmetry results in an average non-zero flow over one period of vibration, which explains the mobilization effect. The minimum-amplitude and maximum-frequency thresholds apply for the mobilization to occur. When the vibration amplitude exceeds a certain "saturation" level, the flow returns to the Darcy regime. The criterion of the mobilization of a particular ganglion involves the parameters of both the medium (pore geometry, interfacial and wetting properties, fluid viscosity) and the oscillatory field (amplitude and frequency). The medium parameters vary widely under natural conditions. It follows that an elastic wave with a given amplitude and frequency will always produce a certain mobilization effect, mobilizing some ganglia and leaving others intact. The exact macroscopic effect is hard to predict, as it will represent a response of the populations of ganglia with unknown parameter distributions. The variability of responses to vibratory stimulation should thus be expected.

Managers' experience of success criteria and barriers to implementing mobile radiography services in nursing homes in Norway: a qualitative study.

2018-04-25

In order to meet the future challenges posed by ageing populations, new technology, telemedicine and a more personalized healthcare system are needed. Earlier research has shown mobile radiography services to be highly beneficial for nursing home residents in addition to being cost-effective. Despite the benefits, mobile radiography services are uncommon in Europe and Norway. The purpose of this study was to explore success criteria and barriers in the process of implementing mobile radiography services, from the point of view of the hospital and municipal managers. Eleven semi-structured interviews were conducted with managers from five hospitals and six municipalities in Norway where mobile radiography services had been implemented. Core issues in the interview guide were barriers and facilitators in the different phases of implementation. The framework method for thematic analysis was used for analysing the data inductively in a research team. Five main categories were developed through the success criteria and barriers experienced by the participants: national health policy, regional and municipal policy and conditions, inter-organizational implementation projects, experienced outcome, and professional skills and personal characteristics. The categories were allocated into three higher-order classifications: macro, meso and micro levels. The main barriers experienced by the managers were financial, procedural and structural. In particular, the reimbursement system, lack of management across healthcare levels and the lack of compatible information systems acted as barriers. The main facilitators were external funding, enthusiastic individuals in the organizations and good collaboration between hospitals and municipalities. The managers experienced financial, structural and procedural barriers. The main success criteria in the process were external funding, and the support and engagement from the individuals in the organizations. This commitment was mainly facilitated by the intuitive appeal of mobile radiography. Changes in healthcare management and in the financial system might facilitate services across healthcare levels. In addition, compatible information systems across healthcare levels are needed in order to facilitate the use of new technology and mobile services.

To assess the effectiveness of joint mobilization combined with stretching exercises in patients with frozen shoulder. A randomized controlled clinical pilot trial. Department of Orthopedics and Traumatology. Thirty patients with frozen shoulder. All participants were randomly assigned to one of two treatment groups: joint mobilization and stretching versus stretching exercises alone. Both groups performed a home exercise program and were treated for six weeks (18 sessions). The primary outcome measures for functional assessment were the Disabilities of the Arm, Shoulder and Hand score and the Constant score. The secondary outcome measures were pain level, as evaluated with a visual analog scale, and range of motion, as measured using a conventional goniometer. Patients were assessed before treatment, at the end of the treatment, and after one year as follow-up. Two-by-two repeated-measures ANOVA with Bonferroni corrections revealed significant increases in abduction (91.9° [CI: 86.1-96.7] to 172.8° [CI: 169.7-175.5]), external rotation (28.1° [CI: 22.2-34.2] to 77.7° [CI: 70.3-83.0]) and Constant score (39.1 [CI: 35.3-42.6] to 80.5 [75.3-86.6]) at the one-year follow-up in the joint mobilization combined with stretching exercise group, whereas the group performing stretching exercise alone did not show such changes. In the treatment of patients with frozen shoulder, joint mobilization combined with stretching exercises is better than stretching exercise alone in terms of external rotation, abduction range of motion and function score. © The Author(s) 2015.

A Programmable Power Processor (P3) has been developed for application in future large space power systems. The P3 is capable of operation over a wide range of input voltage (26 to 375 Vdc) and output voltage (24 to 180 Vdc). The peak output power capability is 18 kW (180 V at 100 A). The output characteristics of the P3 can be programmed to any voltage and/or current level within the limits of the processor and may be controlled as a function of internal or external parameters. Seven breadboard P3s and one 'flight-type' engineering model P3 have been built and tested both individually and in electrical power systems. The programmable feature allows the P3 to be used in a variety of applications by changing the output characteristics. Test results, including efficiency at various input/output combinations, transient response, and output impedance, are presented.

2016-01-01

Aims and objectives The aim of this study was to generate a theory conceptualizing and explaining behavioural processes involved in coping in order to identify the predominant coping types and coping type-specific features. Background Patients undergoing fast track procedures do not experience a higher risk of complications, readmission, or mortality. However, such programmes presuppose an increasing degree of patient involvement, placing high educational, physical, and mental demands on the patients. There is a lack of knowledge about how patients understand and cope with fast track programmes. Design The study design used classical grounded theory. Methods The study used a multimodal approach with qualitative and quantitative data sets from 14 patients. Results Four predominant types of coping, with distinct physiological, cognitive, affective, and psychosocial features, existed among patients going through a fast track total hip replacement programme. These patients’ main concern was to restore their physical and psychosocial integrity, which had been compromised by reduced function and mobility in daily life. To restore integrity they economized their mental resources, while striving to fulfil the expectations of the fast track programme. This goal was achieved by being mentally proactive and physically active. Three out of the four predominant types of coping matched the expectations expressed in the fast track programme. The non-matching behaviour was seen among the most nervous patients, who claimed the right to diverge from the programme. Conclusion In theory, four predominant types of coping with distinct physiological, cognitive, affective, and psychosocial features occur among patients going through a fast track total hip arthroplasty programme.

Sustainability of health promotion and injury prevention programmes is a goal of practitioners and an increasingly common requirement of funding bodies. However, less is known about the views held by individual stakeholders involved in such programmes regarding their perceptions of facilitators and barriers to achieving sustainability. This paper aims to share the perceptions of programme sustainability held by key stakeholders involved in a community-based fall prevention programme in three Ontario demonstration communities in Canada. A qualitative case study research design. A holistic multiple case study method was employed. In total, 45 stakeholders involved in various aspects of the project participated from three demonstration sites. Stakeholders' perceptions were gathered on the individual actions they took in an effort to promote sustainability, and the barriers they perceived as preventing or limiting sustainability. Stakeholders reported taking a number of actions to aid programme sustainability, with some actions deemed to be more functional in aiding sustainability than others. Common actions reported by stakeholders included partnership formation, networking and increasing community capacity. Stakeholders also perceived a number of barriers to achieving sustainability, including insufficient human and financial resources, lack of co-ordination and buy-in, heavy reliance on volunteers and an inability to mobilize physicians. Stakeholders' perceptions of sustainability were used to develop recommendations for sustainability for both communities and funding bodies. The views and experiences shared by the stakeholders in this project can serve as lessons learnt to aid in the sustainability of other health promotion and injury prevention programmes in the future.

India's Universal Immunization Programme (UIP) is one of the largest programmes in the world in terms of quantities of vaccines administered, number of beneficiaries, number of immunization sessions, and geographical extent and diversity of areas covered. Strategic planning for the Programme requires credible information on the cost of achieving the objectives and the financial resources needed at national, State, and district levels. We present here expenditures on immunization services in India in 2012 (baseline) and projected costs for five years (2013-2017). Data were collected from the Immunization Division of the Ministry of Health and Family Welfare, Government of India, and immunization partners, such as the World Health Organization and UNICEF. The cost components were immunization personnel, vaccines and injection supplies, transportation, trainings, social mobilization, advocacy and communication activities, disease surveillance, Programme management, maintenance of cold chain and other equipment, and capital costs. Total baseline expenditure was ₹ 3,446 crore [1 crore = 10 million] (US$718 million), including shared personnel costs. In 2012, the government paid for 90 per cent of the Programme. Total resource requirements for 2013-2017 are ₹ 34,336 crore (US$ 5, 282 million). Allocations for vaccines increase from ₹ 511 crore in 2013 to ₹ 3,587 crore in 2017 as new vaccines are assumed to be introduced in the Programme. The projections show that the government immunization budget will be double in 2017 as compared to 2013. It will increase from ₹ 4,570 crore in 2013 to ₹ 9,451 crore in 2017.

Abstract Developing countries currently face internal and external migration of their health workforce and interventions are needed to attract and retain health professionals in rural areas. Evidence of multidimensional interventions, however, is scarce. This study explores a long-standing strategy to attract and retain doctors to rural areas in Chile: the Rural Practitioner Programme. The main objective is to describe the programme, characterize its multidimensional set of incentives and appraise preliminary programme outcomes. Retrospective national data were employed to examine recruitment, retention and incentives provided to extend the length of stay and motivate non-clinical work. The programme has successfully recruited a large number of applicants, with acceptance rates close to 100%. Retention rates are nearly 100% (drop-outs are exceptional), but only 58% of participants stay for the maximum period. Areas with greater work difficulty are attracting the best-ranked applicants, but incentives to engage in community projects, management responsibilities, continuous medical education and research have achieved mixed results. Rural doctors are satisfied with their experience and 70% plan to practise as specialists in a referral hospital. The programme has successfully matched the interests of physicians in specialization with the country’s need for rural doctors. However, a gap might be forming between the demand for certain specialties and what the programme can offer. There is a need to conciliate both parties, which will require a more refined strategy than before. This should be grounded in robust knowledge based on programme outcomes and evidence of the interests and motivations of health professionals. PMID:20461139

The STS-93 stack of solid rocket boosters and external tank sits at the Mobile Launcher Platform park site waiting for lightning shield wires to be installed on the Vehicle Assembly Building (VAB) in the background. The stack is being temporarily stored outside the VAB while Space Shuttle Discovery undergoes repair to hail damage in High Bay 1. Discovery was rolled back from Pad 39B to the VAB for repairs because access to all of the damaged areas was not possible at the pad. The STS-93 stack will be moved under the wires at the VAB for protection until Discovery returns to the pad, later this week. The scheduled date for launch of mission STS-96 is no earlier than May 27. STS-93 is targeted for launch on July 22, carrying the Chandra X-ray Observatory.

In chronic obstructive pulmonary disease (COPD), the problem of poor patient participation in studies of self-management (SM) and pulmonary rehabilitation (PR) programmes (together referred to as COPD support programmes) is established. Understanding this problem beyond the previously reported socio-demographics and clinical factors is critical. The aim of this study was to explore factors that explain patient participation in studies of COPD support programmes. Thematic 'framework' synthesis was conducted on literature published from 1984 to 1 February 2015. Emergent themes and subthemes were mapped onto the adapted 'attitude-social influence-external barriers' and the 'self-regulation' models to produce analytical themes. Ten out of 12 studies were included: PR (n=9) and SM (n=1). Three descriptive themes with 38 subthemes were mapped onto the models' constructs, and it generated four analytical themes: 'attitude', 'social influences' and 'illness' and 'intervention representations'. The following factors influenced (1) attendance-helping oneself through health improvements, perceived control of worsening condition, perceived benefits and positive past experience of the programme, as well as perceived positive influence of professionals; (2) non-attendance-perceived negative effects and negative past experience of the programme, perceived physical/practical concerns related to attendance, perceived severity of condition/symptoms and perceived negative influence of professionals/friends; (3) dropout-no health improvements perceived after attending a few sessions of the programme, perceived severity of the condition and perceived physical/practical concerns related to attendance. Psychosocial factors including perceived practical/physical concerns related to attendance influenced patients' participation in COPD support programmes. Addressing the negative beliefs/perceptions via behaviour change interventions may help improve participation in COPD support programmes and, ultimately, patient outcomes.

We conducted a qualitative study to examine the impact of an HIV prevention programme on female sex workers' lives in Guntur district, Andhra Pradesh. The study found evidence that, in addition to the HIV prevention programme, structural and environmental factors had recently changed the way sex work was being practiced. Recent closure of the brothels and implementation of a late-night street curfew by the police meant sex work had become more hidden, with clients often solicited using mobile phones from home or their work place (e.g., in the fields or factories). Sex work had become safer, with violence by non-regular partners rarely reported. Women understood the risks of unprotected vaginal sex and reported using condoms with their clients. However, clients were more frequently requesting anal sex, possibly due to recent exposure to pornography following increased accessibility to modern technologies such as mobile phones and the Internet. Anal sex with clients was common but women were often unaware of the associated risks and reported unprotected anal sex. HIV positive and/or older women faced severe financial hardship and difficulty soliciting sufficient clients, and reported unprotected vaginal and anal sex to earn enough to survive. Taken together, the findings from this study suggest changing vulnerability to HIV in this setting. It will be important for HIV prevention programmes to be flexible and creative in their approaches if they are to continue to reach this target community effectively.

Roles of laboratories and laboratory systems in effective tuberculosis programmes.

Laboratories and laboratory networks are a fundamental component of tuberculosis (TB) control, providing testing for diagnosis, surveillance and treatment monitoring at every level of the health-care system. New initiatives and resources to strengthen laboratory capacity and implement rapid and new diagnostic tests for TB will require recognition that laboratories are systems that require quality standards, appropriate human resources, and attention to safety in addition to supplies and equipment. To prepare the laboratory networks for new diagnostics and expanded capacity, we need to focus efforts on strengthening quality management systems (QMS) through additional resources for external quality assessment programmes for microscopy, culture, drug susceptibility testing (DST) and molecular diagnostics. QMS should also promote development of accreditation programmes to ensure adherence to standards to improve both the quality and credibility of the laboratory system within TB programmes. Corresponding attention must be given to addressing human resources at every level of the laboratory, with special consideration being given to new programmes for laboratory management and leadership skills. Strengthening laboratory networks will also involve setting up partnerships between TB programmes and those seeking to control other diseases in order to pool resources and to promote advocacy for quality standards, to develop strategies to integrate laboratories functions and to extend control programme activities to the private sector. Improving the laboratory system will assure that increased resources, in the form of supplies, equipment and facilities, will be invested in networks that are capable of providing effective testing to meet the goals of the Global Plan to Stop TB.

An analysis undertaken jointly in 2009 by the UN World Food Programme, The Partnership for Child Development and the World Bank was published as Rethinking School Feeding to provide guidance on how to develop and implement effective school feeding programmes as a productive safety net and as part of the efforts to achieve Education for All. The present paper reflects on how understanding of school feeding has changed since that analysis. Data on school feeding programme outcomes were collected through a literature review. Regression models were used to analyse relationships between school feeding costs (from data that were collected), the per capita costs of primary education and Gross Domestic Product per capita. Data on the transition to national ownership, supply chains and country examples were collected through country case studies. School feeding programmes increase school attendance, cognition and educational achievement, as well as provide a transfer of resources to households with possible benefits to local agricultural production and local market development. Low-income countries exhibit large variations in school feeding costs, with concomitant opportunities for cost containment. Countries are increasingly looking to transition from externally supported projects to national programmes. School feeding is now clearly evident as a major social programme in most countries with a global turnover in excess of $US 100 billion. This argues for a continuing focus on the evidence base with a view to helping countries ensure that their programmes are as cost-effective as possible. Clear policy advice has never been more important.

The European Society of Cardiology (ESC) offers a variety of grants/fellowships to help young professionals in the field of cardiological training or research activities throughout Europe. The number of grants has significantly increased in recent years with contributions from the Associations, Working Groups and Councils of the ESC. The European Association of Echocardiography (EAE) is a registered branch of the ESC and actively takes part in this initiative. One of the aims of EAE is to promote excellence in research in cardiovascular ultrasound and other imaging modalities in Europe. Therefore, since 2008, the EAE offers a Research Grant Programme to help young doctors to obtain research experience in a high standard academic centre (or similar institution oriented to clinical or pre-clinical research) in an ESC member country other than their own. This programme can be considered as a valorization of the geographical mobility as well as cultural exchanges and professional practice in the field of cardiovascular imaging. The programme has been very successful so far, therefore in 2012 the EAE has increased its offer to two grants of 25,000 euros per annum each.

Terahertz electromodulation spectroscopy provides insight into the material-inherent transport properties of charge carriers in organic semiconductors. Experiments on didodecyl[1]benzothieno[3,2-b][1]benzothiophene (C 12 -BTBT-C 12 ) devices yield for holes an intraband mobility of 9 cm 2 V -1 s -1 . The short duration of the THz pulses advances the understanding of the hole transport on the molecular scale. The efficient screening of Coulomb potentials leads to a collective response of the hole gas to external fields, which can be well described by the Drude model. Bias stress of the devices generates deep traps that capture mobile holes. Although the resulting polarization across the device hinders the injection of mobile holes, the hole mobilities are not affected.

High-quality channel layer is required for next-generation flexible electronic devices. Graphene is a good candidate due to its high carrier mobility and unique ambipolar transport characteristics but typically shows a low on/off ratio caused by gapless band structure. Popularly investigated organic semiconductors, such as pentacene, suffer from poor carrier mobility. Here, we propose a graphene/pentacene channel layer with high-k ion-gel gate dielectric. The graphene/pentacene device shows both high on/off ratio and carrier mobility as well as excellent mechanical flexibility. Most importantly, it reveals ambipolar behaviors and related negative differential resistance, which are controlled by external bias. Therefore, our graphene/pentacene barristor with ion-gel gate dielectric can offer various flexible device applications with high performances.

We demonstrate a highly sensitive mobile phone based spectrometer that has potential to detect cancerous skin lesions in a rapid, non-invasive manner. Earlier reports of low cost spectrometers utilize the camera of the mobile phone to image the field after moving through a diffraction grating. These approaches are inherently limited by the closed nature of mobile phone image sensors and built in optical elements. The system presented uses a novel integrated grating and sensor that is compact, accurate and calibrated. Resolutions of about 10 nm can be achieved. Additionally, UV and visible LED excitation sources are built into the device. Data collection and analysis is simplified using the wireless interfaces and logical control on the smart phone. Furthermore, by utilizing an external sensor, the mobile phone camera can be used in conjunction with spectral measurements. We are exploring ways to use this device to measure endogenous fluorescence of skin in order to distinguish cancerous from non-cancerous lesions with a mobile phone based dermatoscope.

Widespread adoption of smart mobile platforms coupled with a growing ecosystem of sensors including passive location tracking and the ability to leverage external data sources create an opportunity to generate an unprecedented depth of data on individuals. Mobile health technologies could be utilized for chronic disease management as well as research to advance our understanding of common diseases, such as asthma. We conducted a prospective observational asthma study to assess the feasibility of this type of approach, clinical characteristics of cohorts recruited via a mobile platform, the validity of data collected, user retention patterns, and user data sharing preferences. We describe data and descriptive statistics from the Asthma Mobile Health Study, whereby participants engaged with an iPhone application built using Apple's ResearchKit framework. Data from 6346 U.S. participants, who agreed to share their data broadly, have been made available for further research. These resources have the potential to enable the research community to work collaboratively towards improving our understanding of asthma as well as mobile health research best practices.

Using Unconstrained Tongue Motion as an Alternative Control Mechanism for Wheeled Mobility

Tongue drive system (TDS) is a tongue-operated, minimally invasive, unobtrusive, noncontact, and wireless assistive technology that infers users’ intentions by detecting and classifying their voluntary tongue motions, and translating them to user-defined commands. We have developed customized interface circuitry between an external TDS (eTDS) prototype and a commercial powered wheelchair (PWC) as well as three control strategies to evaluate the tongue motion as an alternative control input for wheeled mobility. We tested the eTDS performance in driving PWCs on 12 able-bodied human subjects, of which 11 were novice. The results showed that all subjects could complete navigation tasks by operating the PWC using their tongue motions. Despite little prior experience, the average time using the eTDS and the tongue was only approximately three times longer than using a joystick and the fingers. Navigation time was strongly dependant on the number of issued commands, which reduced by gaining experience. Particularly, the unintended issued commands (the Midas touch problem) were rare, demonstrating the effectiveness of the tongue tracking and external magnetic field cancellation algorithms as well as the safety of the TDS for wheeled mobility.

2016-06-13

Resistance switching phenomena were studied by varying temperature in SrTiO{sub 3} single crystal. The resistance hysteresis loops appear at a certain temperature ranging from 340 K to 520 K. With the assistance of 375 nm ultraviolet continuous laser, the sample resistance is greatly reduced, leading to a stable effect than that in dark. These resistance switching phenomena only exist in samples with enough oxygen vacancies, which is confirmed by spherical aberration-corrected scanning transmission electron microscopy measurements, demonstrating an important role played by oxygen vacancies. At temperatures above 340 K, positively charged oxygen vacancies become mobile triggered by external electric field, and the resistance switchingmore » effect emerges. Our theoretical results based on drift-diffusion model reveal that the built-in field caused by oxygen vacancies can be altered under external electric field. Therefore, two resistance states are produced under the cooperative effect of built-in field and external field. However, the increasing mobility of oxygen vacancies caused by higher temperature promotes internal electric field to reach equilibrium states quickly, and suppresses the hysteresis loops above 420 K.« less

A Characteristic Dose Model for Historical Internal Dose Reconstruction in the Framework of the IAEC Compensation Programme.

A model was developed at the Nuclear Research Centre Negev (NRCN) to assess historical doses from internal exposures by a relatively fast and simple procedure. These assessments are needed in the framework of a compensation programme for the Israeli Atomic Energy Commission (IAEC) workers, which were diagnosed for cancer diseases. This compensation programme was recently recommended by a public committee to avoid lengthy court procedures. The developed model is based on the recorded doses from external exposures of all the workers at the NRCN, who were divided into groups representing their different working environments. Each group of workers was characterised by three parameters: working period, working areas and occupation. The model uses several conservative assumptions in order to calculate the doses to various body organs in certain years, which are relevant to the calculation of the probability of causation (POC). The POC value serves as a main parameter in the compensation programme. © The Author 2016. Published by Oxford University Press. All rights reserved.

India is a high TB burden country. The preferred first line diagnostic tool under National TB Programme is sputum smear microscopy through binocular microscopes (BMs) from 13,000 designated microscopy centres across the country. The programme had devised innovative strategy for maintenance of BMs. A study was conducted to look into the operational feasibility of an external agency to provide maintenance services for BMs engaged through newer strategy. A cross-sectional study was conducted in the states of Uttar Pradesh, Bihar and Rajasthan during 2010-2013. A total of 9314 BMs were serviced during the period 2011-2013, of which 1104 (11.8%) had major repairs, 2204 (23.6%) had minor repairs, 1054 (11.3%) were provided emergency breakdown services and 223 (2.4%) were condemned. The bold initiative and newer strategy of the programme to engage agencies for BMs maintenance services is worthwhile and should be continued and could be considered for replication across the country.

AIPS++ is an Astronomical Information Processing System being designed and implemented by an international consortium of NRAO and six other radio astronomy institutions in Australia, India, the Netherlands, the United Kingdom, Canada, and the USA. AIPS++ is intended to replace the functionality of AIPS, to be more easily programmable, and will be implemented in C++ using object-oriented techniques. Programmability in AIPS++ is planned at three levels. The first level will be that of a command-line interpreter with characteristics similar to IDL and PV-Wave, but with an intensive set of operations appropriate to telescope data handling, image formation, and image processing. The third level will be in C++ with extensive use of class libraries for both basic operations and advanced applications. The third level will allow input and output of data between external FORTRAN programs and AIPS++ telescope and image databases. In addition to summarizing the above programmability characteristics, this talk will given an overview of the classes currently being designed for telescope data calibration and editing, image formation, and the 'toolkit' of mathematical 'objects' that will perform most of the processing in AIPS++.

The effect of ankle position on the exam for first ray mobility.

Grebing, Brett R; Coughlin, Michael J

2004-07-01

The clinical assessment of first ray motion in the sagittal plane, as originally described by Morton, is difficult to quantify. Different reports have shown inconsistent values and variability between the manual exam and examination using an external measuring device. The authors hypothesize that when performing a manual examination for evidence of increased first ray motion, the magnitude of first ray mobility varies as the position of ankle dorsiflexion/plantarflexion varies. Using an external caliper (a modified Klaue device), the authors quantified first ray motion in reference to variable ankle positions in a group of normal patients, a group of patients with untreated moderate and severe hallux valgus, a group who had undergone a successful metatarsophalangeal joint arthrodesis for hallux valgus, and a small group who had previously undergone a plantar fasciectomy. A total of 119 feet (109 patients) were measured. In addition to first ray motion, radiographic data were compared between groups. With the ankle in the neutral dorsiflexion position, the mean first ray motion was 4.9 mm for the control group, 7.0 mm for the hallux valgus group, 4.4 mm for the metatarsophalangeal fusion group, and 7.7 mm for the plantar fasciectomy group. There was a significant decrease (p < .05) in first ray motion when the ankle was moved to the dorsiflexed position for all four groups. There was a significant increase in first ray motion when the ankle was moved to the plantarflexed position (p < .01) for all groups except the plantar fasciectomy group. No significant difference in first ray motion was observed for the plantar fasciectomy group between the neutral and plantarflexed ankle positions (p < .05). The exam for first ray mobility is influenced by the position of the ankle and may explain the discrepancy between the manual exam and measurement with an external device. Recommendations for the manual exam of first ray mobility are given.

Which preparatory curriculum for the International Baccalaureate Diploma Programme is best? The challenge for international schools with regard to mathematics and science

2014-12-01

There are two mainstream curricula for international school students at the junior high level: the International Baccalaureate (IB) Middle Years Programme (MYP) and the Cambridge International General Certificate of Secondary Education (IGCSE). The former was developed in the mid-1990s and is currently being relaunched in a 21st-century approach. The latter programme of study was developed by University of Cambridge International Examinations in 1985 and has become popular in recent years among British domestic and international schools worldwide due to the clarity of its learning content. The prevailing uncertainty about which curriculum is best to prepare students for the IB Diploma Programme represents a challenge for international schools. The purpose of the current study is to develop a methodology through causal models which can explain the relationship between student performance in the IGCSE and the Diploma Programme with regard to mathematics and science. The data evaluated here consisted of external examination scores of students who attended a private international high school between the years 2005 and 2012. Two structural equation models were developed. The first model employed a maximum likelihood estimation, while the second model used a Bayesian estimation with a Markov Chain Monte Carlo method. Both models fit the data well. The evidence suggests that the IGCSE provides a good foundational preparation for the Diploma Programme in mathematics and science.

We describe an open-source freeware programme for high throughput analysis of nanoSIMS (nanometre-scale secondary ion mass spectrometry) data. The programme implements basic data processing and analytical functions, including display and drift-corrected accumulation of scanned planes, interactive and semi-automated definition of regions of interest (ROIs), and export of the ROIs' elemental and isotopic composition in graphical and text-based formats. Additionally, the programme offers new functions that were custom-designed to address the needs of environmental microbiologists. Specifically, it allows manual and automated classification of ROIs based on the information that is derived either from the nanoSIMS dataset itself (e.g. from labelling achieved by halogen in situ hybridization) or is provided externally (e.g. as a fluorescence in situ hybridization image). Moreover, by implementing post-processing routines coupled to built-in statistical tools, the programme allows rapid synthesis and comparative analysis of results from many different datasets. After validation of the programme, we illustrate how these new processing and analytical functions increase flexibility, efficiency and depth of the nanoSIMS data analysis. Through its custom-made and open-source design, the programme provides an efficient, reliable and easily expandable tool that can help a growing community of environmental microbiologists and researchers from other disciplines process and analyse their nanoSIMS data. © 2012 Society for Applied Microbiology and Blackwell Publishing Ltd.

Morocco's severe financial problems have threatened its health-for-all goals. Restrictions have affected the recruitment and replacement of health personnel, the purchase and maintenance of equipment and buildings, hospital catering services and drug procurement. Several methods have been used to try and ease this crisis, rationalization and better deployment of resources, mobilization of national resources, and mobilization of external resources. In attaining the 1st, restrictions on the credits allocated to the Ministry of Public health have forced it to work out better ways of using its resources. These have included plans for better administrative and financial management of hospitals, improvements in drug procurement and distribution, new methods of personnel management, and efforts at improving information facilities and analytical capabilities at the central and local levels. To mobilize internal resources several steps were taken. These included revising too-low hospital charges, and charging people with social security coverage or those able to pay directly, raising funds through private charities, and the establishment of alternative, less expensive types of health centers. Morocco's continued need for funds to achieve health-for-all goals led it to also receive substantial assistance from international agencies (including the World Bank, UNICEF, UNFPA, and USAID) and friendly countries. External assistance cannot provide definitive solutions however, because of 1) the use of foreign experts and the payment of salaries abroad, 2) the purchase of products from the countries providing assistance, and 3) the unpredictability of external support and the danger programs may have to be abandoned. In times of financial crisis it is necessary to continue to budget adequately in order to reach health objectives.

Spinal mobility and trunk muscle strength in elite hockey players.

PubMed

Lindgren, S; Twomey, L

1988-01-01

Elite hockey players of both sexes from the Australian Institute of Sport were assessed for lumbar spine mobility, trunk flexion and back extensor muscle strength, hamstring flexibility and postural characteristics over a two year period. All the athletes were more mobile in rotation than the 'normal' West Australian population, and demonstrated flexible hamstrings and powerful back extensor muscles; trunk flexion was less strong initially, but improved after intervention in the form of a specific exercise programme, over the measurement period. A questionnaire disclosed that low back pain is a common complaint of hockey players, but rarely required intensive physical and medical treatment. The term 'hockey player's back' has been coined in recognition of the long flat thoracolumbar spine frequently noted in these subjects. Copyright © 1988 Australian Physiotherapy Association.

The effect of an active implementation of a disease management programme for chronic obstructive pulmonary disease on healthcare utilization - a cluster-randomised controlled trial

PubMed Central

2013-01-01

Background The growing population living with chronic conditions calls for efficient healthcare-planning and effective care. Implementing disease-management-programmes is one option for responding to this demand. Knowledge is scarce about the effect of implementation processes and their effect on patients; only few studies have reported the effectiveness of disease-management-programmes targeting patients with chronic obstructive pulmonary disease (COPD). The objective of this paper was to determine the effect on healthcare-utilization of an active implementation model for a disease-management-programme for patients with one of the major multimorbidity diseases, COPD. Methods The standard implementation of a new disease-management-programme for COPD was ongoing during the study-period from November 2008 to November 2010 in the Central Denmark Region. We wanted to test a strategy using Breakthrough Series, academic detailing and lists of patients with COPD. It targeted GPs and three hospitals serving approx. 60,000 inhabitants aged 35 or older and included interventions directed at professionals, organisations and patients. The study was a non-blinded block- and cluster-randomised controlled trial with GP-practices as the unit of randomisation. In Ringkoebing-Skjern Municipality, Denmark, 16 GP-practices involving 38 GPs were randomised to either the intervention-group or the control-group. A comparable neighbouring municipality acted as an external-control-group which included nine GP-practices with 25 GPs. An algorithm based on health-registry-data on lung-related contacts to the healthcare-system identified 2,736 patients who were alive at the end of the study-period. The population included in this study counted 1,372 (69.2%) patients who responded to the baseline questionnaire and confirmed their COPD diagnosis; 458 (33.4%) patients were from the intervention-group, 376 (27.4%) from the control-group and 538(39.2%) from the external-control-group. The primary outcome was adherence to the disease-management-programme measured at patient-level by use of specific services from general practice. Secondary outcomes were use of out-of-hours-services, outpatient-clinic, and emergency-department and hospital-admissions. Results The intervention practices provided more planned preventive consultations, additional preventive consultations and spirometries than non-intervention practices. A comparison of the development in the intervention practices with the development in the control-practices showed that the intervention resulted in more planned preventive-consultations, fewer conventional consultations and fewer patients admitted without a lung-related-diagnosis. Conclusions Use of the active implementation model for the disease-management-programme for COPD changed the healthcare utilization in accordance with the programme.

The test facility applies pressure, temperature, and external loads to a short stack of solid rocket motor hardware. The simulated SRM ignition pressure and temperature transients are achieved by firing a small amount of specially configured solid propellant. The pressure transient is synchronized with external programmable dynamic loads that simulate lift off loads at the external tank attach points. Approximately one million pounds of dead weight on top of the test article simulates the weight of the other Shuttle elements.

A digital optical phase lock loop (OPLL) is implemented to synchronize the frequency and phase between two external cavity diode lasers (ECDL), generating Raman pulses for atom interferometry. The setup involves all-digital phase detection and a programmable digital proportional-integral-derivative (PID) loop in locking. The lock generates a narrow beat-note linewidth below 1 Hz and low phase-noise of 0.03rad2 between the master and slave ECDLs. The lock proves to be stable and robust, and all the locking parameters can be set and optimized on a computer interface with convenience, making the lock adaptable to various setups of laser systems.

Cost analysis and exploratory cost-effectiveness of youth-friendly sexual and reproductive health services in the Republic of Moldova.

Youth-friendly sexual and reproductive health services (YFHS) have high priority in many countries. Yet, little is known about the cost and cost-effectiveness of good quality YFHS in resource limited settings. This paper analyses retrospectively costs and potential cost-effectiveness of four well performing youth-friendly health centres (YFHC) in Moldova. This study assesses: (1) what were the costs of YFHSs at centre level, (2) how much would scaling-up to a national good quality YFHS programme cost, and (3) was the programme potentially cost-effective? Four well performing YFHCs were selected for the study. YFHS costs were analysed per centre, funding source, service and person reached. The costing results were extrapolated to estimate cost of a good quality national YFHS programme in Moldova. A threshold analysis was carried out to estimate the required impact level for the YFHSs to break-even (become cost saving). Average annual cost of a well performing YFHC was USD 26,000 in 2011. 58% was financed by the National Health Insurance Company and the rest by external donors (42%). Personnel salaries were the largest expense category (47%). The annual implementation costs of a good quality YFHSs in all 38 YFHCs of Moldova were estimated to be USD 1.0 million. The results of the threshold analysis indicate that the annual break-even impact points in a YFHC for: 1) STI services would be >364 averted STIs, 2) early pregnancy and contraceptive services >178 averted unwanted pregnancies, and 3) HIV services only >0.65 averted new HIV infections. The costing results highlight the following: 1) significant additional resources would be required for implementation of a good quality national YFHS programme, 2) the four well performing YFHCs rely heavily on external funding (42%), 3) which raises questions about financial sustainability of the programme. At the same time results of the threshold analysis are encouraging. The result suggest that, together the three SRH components (STI, early pregnancy and contraception, and HIV) are potentially cost saving. High cost savings resulting from averted lifetime treatment cost of HIV infected persons are likely to off-set the costs of STIs and unwanted pregnancies.

TV watching dramatically changes with introduction of new technologies such as Internet-connected TVs, enriched digital broadcasting (DVB), on-demand content, additional programme information, mobile phones and tablets enabling multiscreen functions etc that offer added values to content consumers. In this paper we propose modular advanced TV platform and its enablers enhancing TV watching. They allow users to receive aside of EPG also additional information about broadcasted content, to be reminded of requested programme, to utilize recommendation and search features, thanks to multiscreen functionality to allow users to take watched content with them or transfer it onto another device. The modularity of the platform allows new features to be added in future.

With the explosion of the CubeSat, small sat, and nanosat markets, the need for a robust, highly capable, yet affordable satellite base station, capable of telemetry capture and relay, is significant. The Programmable Ultra-Lightweight System Adaptable Radio (PULSAR) is NASA Marshall Space Flight Center's (MSFC's) software-defined digital radio, developed with previous Technology Investment Programs and Technology Transfer Office resources. The current PULSAR will have achieved a Technology Readiness Level-6 by the end of FY 2014. The extensibility of the PULSAR will allow it to be adapted to perform the tasks of a mobile base station capable of commanding, receiving, and processing satellite, rover, or planetary probe data streams with an appropriate antenna.

The novelties in clinical psychiatry are close to somatic medicine adaptation. The clinical staging concept in psychiatry (as in cancerology) is the result of an early intervention strategy in psychotic disorders. A differentiated mode of understanding of the phases of psychiatric disorders allows a prevention oriented approach. Individualized therapeutic programmes in accordance with specific problematics favors the orientation towards focalised follow-ups, for instance CBT programmes on Internet may be proposed to patients motivated and rather autonomous. Others, on the contrary, less accessible to health care should benefit of the support of a mobile team and specific coaching to return to vocational services. Systematic follow-up of the metabolic syndrome, often induced by atypical antipsychotics, belongs to those basic adjustment processes.

Background Truck drivers have unique health needs, and by virtue of their continuous travel, experience difficulty in accessing healthcare. Currently, planning for effective care is hindered by lack of knowledge about their health needs and about the impact of on-going programmes on this population’s health outcomes. We reviewed healthcare programmes implemented for sub-Saharan African truck drivers, assessed the evaluation methods, and examined impact on health outcomes. Methods We searched scientific and institutional databases, and online search engines to include all publications describing a healthcare programme in sub-Saharan Africa where the main clients were truck drivers. We consulted experts and organisations working with mobile populations to identify unpublished reports. Forest plots of impact and outcome indicators with unadjusted risk ratios and 95% confidence intervals were created to map the impact of these programmes. We performed a subgroup analysis by type of indicator using a random-effects model to assess between-study heterogeneity. We conducted a sensitivity analysis to examine both the summary effect estimate chosen (risk difference vs. risk ratio) and model to summarise results (fixed vs. random effects). Results Thirty-seven publications describing 22 healthcare programmes across 30 countries were included from 5,599 unique records. All programmes had an HIV-prevention focus with only three expanding their services to cover conditions other primary healthcare services. Twelve programmes were evaluated and most evaluations assessed changes in input, output, and outcome indicators. Absence of comparison groups, preventing attribution of the effect observed to the programme and lack of biologically confirmed outcomes were the main limitations. Four programmes estimated a quantitative change in HIV prevalence or reported STI incidence, with mixed results, and one provided anecdotal evidence of changes in AIDS-related mortality and social norms. Most programmes showed positive changes in risk behaviours, knowledge, and attitudes. Our conclusions were robust in sensitivity analyses. Conclusion Diverse healthcare programmes tailored to the needs of truck drivers implemented in 30 sub-Saharan African countries have shown potential benefits. However, information gaps about availability of services and their effects impede further planning and implementation of effective healthcare programmes for truck drivers. PMID:27333301

Should we use automated external defibrillators in hospital wards?

2012-01-01

Automated external defibrillators (AEDs) have shown to improve survival after cardiopulmonary arrest (CPA) in many, but not all clinical settings. A recent study reported that the use of AEDs in-hospital did not improve survival. The current retrospective study reports the results of an in-hospital AED programme in a university hospital, and focuses on the quality of AED use. At Ghent University Hospital 30 AEDs were placed in non-monitored hospital wards and outpatient clinics treating patients with non-cardiac problems. Nurses were trained to use these devices. From November 2006 until March 2011, the AEDs were used in 23 of 39 CPA cases, in only one patient the presenting heart rhythm was ventricular fibrillation and this patient survived. Pulseless electrical activity was present in 14 patients (four survived) and asystole in eight patients (one survived). AEDs were attached to eight patients without CPA, and in 16 patients with CPA AED was not used. The quality of AED use was often suboptimal as illustrated by external artifacts during the first rhythm analysis by the AED in 30% (7/23) and more than 20 seconds delay before restart of chest compressions after the AED rhythm analysis in 50% (9/18). The literature data, supported by our results, indicate that in-hospital AED programmes are unlikely to improve survival after CPA. Moreover, their use is often suboptimal. Therefore, if AEDs are introduced in a hospital, initial training, frequent retraining and close follow-up are essential.

Large-scale road safety programmes in low- and middle-income countries: an opportunity to generate evidence.

The growing burden of road traffic injuries, which kill over 1.2 million people yearly, falls mostly on low- and middle-income countries (LMICs). Despite this, evidence generation on the effectiveness of road safety interventions in LMIC settings remains scarce. This paper explores a scientific approach for evaluating road safety programmes in LMICs and introduces such a road safety multi-country initiative, the Road Safety in 10 Countries Project (RS-10). By building on existing evaluation frameworks, we develop a scientific approach for evaluating large-scale road safety programmes in LMIC settings. This also draws on '13 lessons' of large-scale programme evaluation: defining the evaluation scope; selecting study sites; maintaining objectivity; developing an impact model; utilising multiple data sources; using multiple analytic techniques; maximising external validity; ensuring an appropriate time frame; the importance of flexibility and a stepwise approach; continuous monitoring; providing feedback to implementers, policy-makers; promoting the uptake of evaluation results; and understanding evaluation costs. The use of relatively new approaches for evaluation of real-world programmes allows for the production of relevant knowledge. The RS-10 project affords an important opportunity to scientifically test these approaches for a real-world, large-scale road safety evaluation and generate new knowledge for the field of road safety.

Doctors must ensure they are fit to practise medicine. There is a relationship between unprofessional behaviour at medical school and in subsequent medical practice. This study describes one programme's Fitness to Practice (FtP) policy and outcomes since inception in 2005. FtP notifications were classified into: health or personal; professional attitudes, or external issues. Seriousness was classified as non-critical, critical or extraordinarily critical. Anonymous data were extracted and analysed from a confidential FtP database. There were 157 FtP notifications involving 132 (5.5%) students. 87.2% were for issues with professional attitudes and 80.3% were non-critical. 17 students received more than one FtP notification. Students in clinical years were over-represented (p<0.0001) as were males (57% vs. 43%: p=0.0286). 96% of students continued the programme after remedial action. Two students were excluded from the programme on FtP grounds. The national regulatory body was notified of nine individual students with the potential for on- going FtP concerns. Over 9 years, 5.5% of medical students received a FtP notification, with most of these isolated non-critical incidents of a professional nature. A small subset of students had repeated or serious concerns, underscoring the need for a FtP policy in any medical programme.

Epidemic transmission on random mobile network with diverse infection periods

Li, Kezan; Yu, Hong; Zeng, Zhaorong; Ding, Yong; Ma, Zhongjun

2015-05-01

The heterogeneity of individual susceptibility and infectivity and time-varying topological structure are two realistic factors when we study epidemics on complex networks. Current research results have shown that the heterogeneity of individual susceptibility and infectivity can increase the epidemic threshold in a random mobile dynamical network with the same infection period. In this paper, we will focus on random mobile dynamical networks with diverse infection periods due to people's different constitutions and external circumstances. Theoretical results indicate that the epidemic threshold of the random mobile network with diverse infection periods is larger than the counterpart with the same infection period. Moreover, the heterogeneity of individual susceptibility and infectivity can play a significant impact on disease transmission. In particular, the homogeneity of individuals will avail to the spreading of epidemics. Numerical examples verify further our theoretical results very well.

Electrohydrodynamics (EHD) refers to the direct conversion of electrical energy into mechanical energy of a fluid. Through the use of mobile electrodes, this principle is exploited in a novel fashion for designing and testing a millimeter-scale untethered robot, which is powered harvesting the energy from an external electric field. The robot is designed as an inverted sail-boat, with the thrust generated on the sail submerged in the liquid. The diffusion constant of the robot is experimentally computed, proving that its movement is not driven by thermal fluctuations, and then its kinematic and dynamic responses are characterized for different applied voltages. The results show the feasibility of using EHD with mobile electrodes for powering untethered robots and provide new evidences for the further development of this actuation system for both mobile robots and compliant actuators in soft robotics.

Go-Golborne is a pilot intervention to prevent childhood obesity in the Royal Borough of Kensington and Chelsea between 2014 and 2018. It is a multistrategy approach targeting children aged 0-16 years and their families in all settings where children live, learn and play. This paper describes the methodology and the practical steps in the development of Go-Golborne. The programme uses a quasi-experimental design for the evaluation of changes in weight status using data from the extended National Child Measurement Programme across local schools. For specific behavioural change objectives, baseline self-reported lifestyle measures will be compared against annual follow-up data over the 3-year study period. Qualitative methods will be used to explore the perceptions of stakeholders and participants and organizational change. Go-Golborne aims to mobilize everyone in the community who has a role or interest in shaping the local environment, norms and behaviours across a range of sectors. A community network of local organizations has been established to codesign all programme activities. The Steering Group of Council officers support programme implementation and environmental changes. The programme has identified six specific behaviour change objectives representing the key areas of need in Golborne and all activities in the council and the community target these objectives during specific programme phases. Key components include community capacity building, community-wide social marketing, environment and policy change and evaluation. The programme is currently at the beginning of its implementation phase with activities in the community and council targeting the first behaviour change objective. The pilot aims to test the effectiveness of this approach to support behaviour change and prevent unhealthy weight gain in children using multiple strategies. This programme will inform the development of an intervention model that defines essential programme components, accountability of partner organizations delivering obesity prevention programmes and the effective use of existing assets.

2018-01-01

Introduction Children with cerebral palsy (CP) and other neurodevelopmental disabilities often receive a home programme of exercises to assist in reaching their therapy goals. Adherence to exercise programmes is necessary to attain the level of practice required to achieve goals; however, adherence can be difficult to accomplish. In this paper, we describe the protocol for a randomised controlled trial to evaluate the effectiveness of delivering a home exercise programme to school-age children with disabilities using Physitrack, an online exercise prescription tool with a website or app interface. Methods and analysis Participants aged 6–17 years, with CP or other neurodevelopmental disabilities, receiving community physiotherapy services in Western Australia, will be recruited. Participants will be stratified by age and functional mobility and randomised to either the intervention group, who will complete an 8-week home exercise programme using Physitrack, or the control group, who will complete an 8-week exercise programme without Physitrack. Researcher blinding to group allocation, and participant blinding to outcome, will be maintained. The primary outcome measures are adherence to the home exercise programme with weekly collection of home exercise logs; achievement of individualised goals by phone interview before and after intervention; and correctness of exercise performance by collection and analysis of videos of participants performing home exercises. Secondary outcome measures include enjoyment of physical activity, confidence to complete exercise programme, preferred method of delivery of programme and usability of Physitrack. A sample size of 58 participants will be necessary to see an effect on home programme adherence. Data will be analysed using the intention-to-treat principle. Ethics and dissemination Ethical approval was obtained from Curtin University Human Research Ethics Committee in July 2016 (10391). Outcomes will be disseminated through publication in peer-reviewed journals and presentations at scientific conferences. Trial registration number ACTRN12616000743460; Pre-results. PMID:29362255

Leadership is seen to be central to improving the quality of healthcare and existing research suggests that absence of leadership is related to poor quality and safety performance. Leadership training might therefore provide an important means through which to promote quality improvement and, more widely, performance within the healthcare environment. This article presents an evaluation of the Fellowships in Clinical Leadership Programme, which combines leadership training and quality improvement initiatives with the placement of temporary external clinical champions in Barking, Havering and Redbridge University Hospitals NHS Trust. We assessed impacts of the Programme on individual and organisational change, alongside core enablers and barriers for Programme success. Analyses drew on the principles of a theory-of-change-led realist evaluation, using logic modelling to specify the underlying causal mechanisms of the Programme. Data collection involved a stakeholder workshop, online questionnaires of programme participants, senior managers and support staff (n=114), and follow-up in-depth semi-structured interviews with a subsample of survey participants (n=15). We observed that the Programme had notable impacts at individual and organisational levels. Examples of individual impact included enhanced communication and negotiation skills or increased confidence as a result of multi-modal leadership training. At the organisational level, participants reported indications of behaviour change among staff, with evidence of spill-over effects to non-participants towards a greater focus on patient-centred care. Our findings suggest that there is potential for combined leadership training and quality improvement programmes to contribute to strengthening a culture of care quality in healthcare organisations. Our study provides useful insights into strategies seeking to achieve sustainable improvement in NHS organisations.

Enhancing frontline clinical leadership in an acute hospital trust.

To report on a leadership programme for ward managers in one National Health Service Trust that aimed to enhance their contribution to the delivery of the organisation's key objectives to support excellent patient experience. Effective ward leadership has been recognised as vital to the quality of care, resource management and interprofessional working. However, there is evidence that, at present, front-line nurse leaders are ill equipped to lead effectively and lack confidence in their ability to do so. The project aimed to provide a tailored programme for ward managers to develop their portfolio of skills to perform this pivotal role. The course contained two key elements: an integrated teaching programme to enhance leadership knowledge and skills and action learning to facilitate application to individual's own leadership practice. Both were underpinned by a change project where each individual identified, undertook and evaluated an innovation in practice. Twenty-two ward managers completed the leadership programme. Participants completed semi-structured questionnaires after each taught module. Action learning was evaluated through a combined structured and semi-structured questionnaire. All participants evaluated the programme as increasing their repertoire of leadership skills. Following completion of the programme, ward managers continue to work together as an evolving community of practice. Ward managers' development is enhanced by a programme integrating theory, action learning and completion of a ward-based project. Ward managers cannot be effectively developed in isolation. Leadership development is best supported where the organisation is also committed to developing. A leadership development programme that incorporates knowledge from within the organisation with external expertise can be an effective method to enhance front-line clinical leadership. © 2013 Blackwell Publishing Ltd.

Building capacity for medical education research in family medicine: the Program for Innovation in Medical Education (PIME).

Despite the apparent benefits to teaching, many faculty members are reluctant to participate in medical education research (MER) for a variety of reasons. In addition to the further demand on their time, physicians often lack the confidence to initiate MER projects and require more support in the form of funding, structure and guidance. These obstacles have contributed to a decline in physician participation in MER as well as to a perceived decay in its quality. As a countermeasure to encourage physicians to undertake research, the Department of Family Medicine at the University of Ottawa implemented a programme in which physicians receive the funding, coaching and support staff necessary to complete a 2-year research project. The programme is intended primarily for first-time researchers and is meant to serve as a gateway to a research career funded by external grants. Since its inception in 2010, the Program for Innovation in Medical Education (PIME) has supported 16 new clinician investigators across 14 projects. We performed a programme evaluation 3 years after the programme launched to assess its utility to participants. This evaluation employed semi-structured interviews with physicians who performed a research project within the programme. Programme participants stated that their confidence in conducting research had improved and that they felt well supported throughout their project. They appreciated the collaborative nature of the programme and remarked that it had improved their willingness to solicit the expertise of others. Finally, the programme allowed participants to develop in the scholarly role expected by family physicians in Canada. The PIME may serve as a helpful model for institutions seeking to engage faculty physicians in Medical Education Research and to thereby enhance the teaching received by their medical learners.

Emergency nurses working in non-Major Trauma Service (non-MTS) facilities face the challenge of providing immediate care to seriously injured patients, despite infrequent presentations at their workplace. A one-day education programme endorsed by the Australian College of Nursing was developed to provide contemporary trauma education for nurses. The aim of this study was to report participants' perceptions of their experience of this programme. Peer reviewed lesson plans were developed to guide educational activities. Of 32 participants, 24 consented to and completed pre and post-programme surveys. Thematic analysis and descriptive statistics were used to report study findings. Most participants were nurses with greater than two years' experience in Emergency Nursing (92%). Trauma patient transfers each year from a non-MTS to a Major Trauma Service occurred infrequently; eight nurses (33.3%) reported greater than10 trauma transfers per year. Participant expectations of the programme included personal growth, knowledge acquisition, increased confidence and a focus on technical skills. Participants reported the day to be worthwhile and valuable; improved confidence, increased knowledge, and the opportunity to discuss current evidence based practice were highly regarded. Recommendations for future programmes included extending to two days and include burns and more complex pathophysiology. With centralisation of trauma care to major trauma services, frequent and continuing education of nurses is essential. Nurses from non-Major Trauma Service facilities in Victoria found this programme worthwhile as they gained knowledge and skills and increased confidence to care for trauma patients.

Motl, Robert W; McAuley, Edward; Suh, Yoojin

2010-01-01

This study examined the structural and external aspects of score validity for the abbreviated Late Life-Function and Disability Inventory (LL-FDI) as well as its longitudinal measurement invariance and responsiveness in individuals with multiple sclerosis (MS). The sample included 292 individuals with MS who completed a battery of questionnaires on two occasions separated by 6 months. The battery included the abbreviated LL-FDI along with measures of mobility disability; neurological impairments; symptoms of fatigue, anxiety, depression and pain; health status; and quality of life. The data were analysed using Analysis of Moment Structures (AMOS) and Statistical Package for the Social Sciences (SPSS), versions 16.0. Confirmatory factor analysis supported the structural validity and longitudinal measurement invariance of the disability and functional limitations components of the abbreviated LL-FDI. MANOVA and bivariate correlations supported the external aspects of score validity based on differences in mean scores as a function of clinical MS course (relapsing vs. progressive) and level of mobility disability (mild vs. moderate mobility disability) and associations with measures of neurological impairments, symptoms, health status and QOL, respectively. ANOVA established the responsiveness (i.e., sensitivity for reflecting clinically important differences in health status across time) of the functional limitations and disability components of the abbreviated LL-FDI for detecting changes in mobility disability across 6-months. Such findings provide a new option for the measurement of functional limitations and disability using the abbreviated LL-FDI in persons with MS.

Given that today's smartphones are mobile and have more computing power and means to measure the external world than early PCs, they may also revolutionize data collection, both in structured physics laboratory settings and in less predictable situations, outside the classroom. Several examples using the internal sensors available in a smartphone were presented in earlier papers in this column.1, 2 But data collection is not limited only to the phone's internal sensors since most also have a headphone port for connecting an external microphone and speakers. This port can be used to connect to external equipment in much the same way as the game port on the early Apple II was used in school labs. Below is an illustration using the headphone port to receive data from an external circuit: smartphones as a portable oscilloscope using commercially available hardware and applications.

Many centers have adopted central vein cannulation both for central venous pressure monitoring and fluid administration for right hepatectomy in living-liver donors. However, use of central venous catheters is associated with adverse events that are hazardous to patients and expensive to treat. This study sought to examine the use of external jugular venous pressure as an alternative to conventional central venous pressure in right lobe donor hepatectomies Forty ASA grade I adult living liver-donors without a known history of significant cardiac or pulmonary diseases were enrolled in this prospective observational study. Paired measurement of venous pressures (external jugular venous pressure and internal jugular venous pressure) were taken at the following times: after induction of anesthesia, 30 minutes after skin incision, during right lobe mobilization (every 15 minutes), during hepatic transaction (every 15 minutes), after right lobe resection (every 15 minutes), and after abdominal closure. Paired measurements were equal in 47.5%, 53.5%, 61.5%, 46.3%, and 52.5% for after induction, after skin incision, right lobe mobilization, right lobe transection, after resection, and before abdominal closure periods. However, all measurements were within acceptable limits of bias measurements (± 2 mm Hg). Central venous pressure catheter placement can be avoided and replaced by a less-invasive method such as external jugular venous pressure (which gave an acceptable estimate of central venous pressure in all phases of right lobe resection) in living-donor liver transplant and allowed equivalent monitor even during fluid restriction phases.

Roles of laboratories and laboratory systems in effective tuberculosis programmes

2007-01-01

Abstract Laboratories and laboratory networks are a fundamental component of tuberculosis (TB) control, providing testing for diagnosis, surveillance and treatment monitoring at every level of the health-care system. New initiatives and resources to strengthen laboratory capacity and implement rapid and new diagnostic tests for TB will require recognition that laboratories are systems that require quality standards, appropriate human resources, and attention to safety in addition to supplies and equipment. To prepare the laboratory networks for new diagnostics and expanded capacity, we need to focus efforts on strengthening quality management systems (QMS) through additional resources for external quality assessment programmes for microscopy, culture, drug susceptibility testing (DST) and molecular diagnostics. QMS should also promote development of accreditation programmes to ensure adherence to standards to improve both the quality and credibility of the laboratory system within TB programmes. Corresponding attention must be given to addressing human resources at every level of the laboratory, with special consideration being given to new programmes for laboratory management and leadership skills. Strengthening laboratory networks will also involve setting up partnerships between TB programmes and those seeking to control other diseases in order to pool resources and to promote advocacy for quality standards, to develop strategies to integrate laboratories’ functions and to extend control programme activities to the private sector. Improving the laboratory system will assure that increased resources, in the form of supplies, equipment and facilities, will be invested in networks that are capable of providing effective testing to meet the goals of the Global Plan to Stop TB.

The South Pacific region is experiencing significant rates of chronic diseases. Well-evaluated health promotion programmes are needed as a central piece of a strategic solution. Just as important as the evaluation itself is how that evaluation outcome can be communicated for future programme use by local programme planners. The objective of this study is to evaluate a physical activity (PA) programme that was designed for Pacific women in urban Vanuatu, and subsequently to develop new techniques to display data that support the understanding and communication of programme success and challenges. Data collection methods included quantitative Likert scale questions and qualitative open-ended questions. A new analysis technique visualises open-ended process evaluation data. We present themes using word sizes proportional to the frequency of the themes identified through thematic analysis. The Likert scale technique revealed little meaningful information; almost all participants rated most elements of the programme highly. This may be related to Pacific people being frequently inclined to assent with external ideas. Open-ended questions provided more significant insights. For example, we found a stronger change in eating habits (68.9%) than in exercise behaviour (28.2%). We present an evaluation of the first pedometer-based PA intervention in the Pacific and respond to the paucity of process evaluations that have been carried out in the context of low- and middle-income countries. Moreover, the new thematic data visualisation (TDV) approach may aid in understanding complex and cluttered data in a constructive and coordinated way; we present a new approach in health promotion research. © The Author(s) 2014.

Communication and social capital in the control of avian influenza: lessons from behaviour change experiences in the Mekong Region.

PubMed

Waisbord, S R; Michaelides, T; Rasmuson, M

2008-01-01

International development agencies, national governments, and nongovernmental organizations are increasingly collaborating with local civil society groups in mounting behaviour change communication (BCC) interventions. Even in countries with weakened civil societies, the social capital of local organizations can be a fundamental communication resource. The experience of three programmes in the Mekong Region that used BCC to prevent and control outbreaks of avian influenza bore out this finding. These programmes worked with the Vietnam Women's Union to mobilize local women as conduits for education; worked with the Centre d'Etude et de Developpement Agricole Cambodgien (CEDAC), in Cambodia, to educate and train village health promoters and model farmers; and worked with the Lao Journalists Association to educate and build skills among print and broadcast journalists to enhance avian influenza coverage. Collaborating with civil society organizations can enhance communication reach, trust, and local ownership, but poses many challenges, particularly institutional capacity. Our experience, nevertheless, holds promise for a measured approach that views social capital as a set of communication resources at the community level that can be mobilized to promote complex behaviours, particularly in a rapidly changing outbreak situation.

Mobile satellite telecommunications systems have undergone an enormous evolution in the last decades, with the interest in having advanced telecommunications services available on demand, anywhere and at any time, leading to incredible advances. The demand for braodband data is therefore rapidly gathering pace, but current solutions are finding it increasingly difficult to combine large bandwidth with ubiquitous coverage, reliability and portability. The BGAN (Broadband Global Area Network) system, designed to operate with the Inmarsat-4 satellites, provides breakthrough services that meet all of these requirements. It will enable broadband connection on the move, delivering all the key tools of the modern office. Recognising the great impact that Inmarsat's BGAN system will have on the European satellite communications industry, and the benefits that it will bring to a wide range of European industries, in 2003 ESA initiated the "BGAN Extension" project. Its primary goals are to provide the full range of BGAN services to truly mobile platforms, operating in aeronautical, vehicular and maritime environments, and to introduce a multicast service capability. The project is supported by the ARTES Programme which establishes a collaboration agreement between ESA, Inmarsat and a group of key industrial and academic institutions which includes EMS, Logica, Nera and the University of Surrey (UK).

Exploring physical activity behaviour - needs for and interest in a technology-delivered, home-based exercise programme among patients with intermittent claudication.

Supervised walking is a first line therapy in peripheral arterial disease (PAD) with complaints of intermittent claudication. However, uptake of supervised programmes is low. Home-based exercise seems an appealing alternative; especially since technological advances, such as tele-coaching and tele-monitoring, may facilitate the process and support patients when adopting a physically active lifestyle. To guide the development of such an intervention, it is important to identify barriers of physical activity and the needs and interests for technology-enabled exercise in this patient group. PAD patients were recruited at the vascular centre of UZ Leuven (Belgium). A questionnaire assessing PA (SF-International Physical Activity Questionnaire), barriers to PA, and interest in technology-supported exercise (Technology Usage Questionnaire) was completed. Descriptive and correlation analyses were performed. Ninety-nine patients (76 men; mean age 69 years) completed the survey. Physical activity levels were low in 48 %, moderate in 29 %, and high in 23 %. Intermittent claudication itself is the most important barrier for enhanced PA, with most patients reporting pain (93 %), need for rest (92 %), and obstacles worsening their pain (74 %) as barriers. A total of 93 % participants owned a mobile phone; 76 % had Internet access. Eighty-seven reported the need for an exercise programme, with 67 % showing interest in tele-coaching to support exercise. If technology was available, three-quarter stated they would be interested in home-based tele-coaching using the Internet (preferably e-mails, 86 %); 50 % via mobile phone, 87 % preferred text messages. Both were inversely related to age (rpb = 0.363 and rpb = 0.255, p < 0.05). Acquaintance with elastic bands or gaming platforms was moderate (55 and 49 %, respectively), but patients were interested in using them as alternatives (84 and 42 %). Interest in platforms was age-dependent (rs = -0.508, p < 0.01). PAD patients show significant interest in technology-delivered exercise, offering opportunities to develop a guided home-based exercise programme.

Daily mobility, an important aspect of environmental exposures and health behavior, has mainly been investigated in high-income countries. We aimed to identify the main dimensions of mobility and investigate their individual, contextual, and external predictors among men and women living in a peri-urban area of South India. We used 192 global positioning system (GPS)-recorded mobility tracks from 47 participants (24 women, 23 men) from the Cardiovascular Health effects of Air pollution in Telangana, India (CHAI) project (mean: 4.1 days/person). The mean age was 44 (standard deviation: 14) years. Half of the population was illiterate and 55% was in unskilled manual employment, mostly agriculture-related. Sex was the largest determinant of mobility. During daytime, time spent at home averaged 13.4 (3.7) h for women and 9.4 (4.2) h for men. Women's activity spaces were smaller and more circular than men's. A principal component analysis identified three main mobility dimensions related to the size of the activity space, the mobility in/around the residence, and mobility inside the village, explaining 86% (women) and 61% (men) of the total variability in mobility. Age, socioeconomic status, and urbanicity were associated with all three dimensions. Our results have multiple potential applications for improved assessment of environmental exposures and their effects on health.

We have studied the mobility of a mobile tibial implant in total knee arthroplasty (TKA) by a radiographical evaluation. We analyzed mobility of the polyethylene tibial insert of 15 "G2S" TKA implanted for one year or more. We established a dynamic radiographical evaluation. We used 3 weight-bearing radiographs: AP in extension and two lateral (one in extension and one at 90 degrees of flexion), two AP with femoral internal and external rotation, 2 strict lateral X-rays in neutral rotation in antero-posterior replacement with a 25 kilograms strength Telos, and 2 AP in varus and valgus with Telos. Wilcoxon's test and Fisher's exact test were used for statistical evaluation. Our study demonstrated preservation of the polyethylene mobility in tibial TKA implant in all movements: in rotation, in antero-posterior translation with Telos, and even in antero-posterior translation during physiological condition with flexion-extension weight-bearing radiographs. Statistical tests were very significant. We noticed that flexion induced anterior translation of tibial polyethylene when PCL was preserved. This study answered to our question whether mobility of TKA tibial implant persists after implantation. This mobility should reduce loosening forces to the tibia and stress in the polyethylene component. Now we have to determine the amplitude of mobility required to reach this objective.

To assess the effect of the Maternal Newborn Dashboard on six key clinical performance indicators in the province of Ontario, Canada. Interrupted time series using population-based data from the provincial birth registry covering a 3-year period before implementation of the Dashboard and 2.5 years after implementation (November 2009 through March 2015). All hospitals in the province of Ontario providing maternal-newborn care (n=94). A hospital-based online audit and feedback programme. Rates of the six performance indicators included in the Dashboard. 2.5 years after implementation, the audit and feedback programme was associated with statistically significant absolute decreases in the rates of episiotomy (decrease of 1.5 per 100 women, 95% CI 0.64 to 2.39), induction for postdates in women who were less than 41 weeks at delivery (decrease of 11.7 per 100 women, 95% CI 7.4 to 16.0), repeat caesarean delivery in low-risk women performed before 39 weeks (decrease of 10.4 per 100 women, 95% CI 9.3 to 11.5) and an absolute increase in the rate of appropriately timed group B streptococcus screening (increase of 2.8 per 100, 95% CI 2.2 to 3.5). The audit and feedback programme did not significantly affect the rates of unsatisfactory newborn screening blood samples or formula supplementation at discharge. No statistically significant effects were observed for the two internal control outcomes or the four external control indicators-in fact, two external control indicators (episiotomy and postdates induction) worsened relative to before implementation. An electronic audit and feedback programme implemented in maternal-newborn hospitals was associated with clinically relevant practice improvements at the provincial level in the majority of targeted indicators. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

High performance digital read out integrated circuit (DROIC) for infrared imaging

NASA Astrophysics Data System (ADS)

Mizuno, Genki; Olah, Robert; Oduor, Patrick; Dutta, Achyut K.; Dhar, Nibir K.

2016-05-01

Banpil Photonics has developed a high-performance Digital Read-Out Integrated Circuit (DROIC) for image sensors and camera systems targeting various military, industrial and commercial Infrared (IR) imaging applications. The on-chip digitization of the pixel output eliminates the necessity for an external analog-to-digital converter (ADC), which not only cuts costs, but also enables miniaturization of packaging to achieve SWaP-C camera systems. In addition, the DROIC offers new opportunities for greater on-chip processing intelligence that are not possible in conventional analog ROICs prevalent today. Conventional ROICs, which typically can enhance only one high performance attribute such as frame rate, power consumption or noise level, fail when simultaneously targeting the most aggressive performance requirements demanded in imaging applications today. Additionally, scaling analog readout circuits to meet such requirements leads to expensive, high-power consumption with large and complex systems that are untenable in the trend towards SWaP-C. We present the implementation of a VGA format (640x512 pixels 15μm pitch) capacitivetransimpedance amplifier (CTIA) DROIC architecture that incorporates a 12-bit ADC at the pixel level. The CTIA pixel input circuitry has two gain modes with programmable full-well capacity values of 100K e- and 500K e-. The DROIC has been developed with a system-on-chip architecture in mind, where all the timing and biasing are generated internally without requiring any critical external inputs. The chip is configurable with many parameters programmable through a serial programmable interface (SPI). It features a global shutter, low power, and high frame rates programmable from 30 up 500 frames per second in full VGA format supported through 24 LVDS outputs. This DROIC, suitable for hybridization with focal plane arrays (FPA) is ideal for high-performance uncooled camera applications ranging from near IR (NIR) and shortwave IR (SWIR) to mid-wave IR (MWIR) and long-wave IR (LWIR) spectral bands.

2018-06-01

The purpose of this study was to test whether a psychodynamically based group psychotherapeutic programme might improve symptoms, social functions, or quality of life in patients with schizophrenia spectrum disorders and to investigate factors that might predict clinical improvement or dropouts from the programme. A quantitative prospective cohort study. We have investigated 81 patients with schizophrenia spectrum disorders who participated in a 9-month psychodynamically based psychotherapeutic day programme. The patients were assessed at the beginning and end of the programme, and then at 1-year follow-up. The assessment included psychotic manifestations (HoNOS), quality of life (WHOQOL-BREF), demographic data, and daily doses of medication. 21 patients dropped out from the programme, and 46 patients succeeded in undergoing follow-up assessment. The psychotic manifestations (self-rating version of HoNOS) and quality of life measured with WHOQOL-BREF (domains of social relationships and environment) were significantly improved at the end of the programme and at follow-up. However, the manifestations on the version for external evaluators of HoNOS were improved only at follow-up. Years of psychiatric treatment, number of hospitalizations or suicide attempts, and experience of relationships with a partner were negatively related to clinical improvement, whereas symptom severity, current working, or study activities were related positively. The results show that a group psychodynamic programme may improve the clinical status and quality of life of patients with schizophrenia spectrum disorders. This type of programme is more beneficial for patients with higher pre-treatment symptom severity and the presence of working or study activities. A psychodynamically based group programme improves the clinical status and quality of life in patients with schizophrenia spectrum disorders. Data indicate that changes on the subjective level are detectable by the end of the programme, while changes on the objective level are detectable at follow-up assessment. Symptom severity and working or study activities are positively related to the clinical improvement in this type of programme, while a high number of years in psychiatric treatment or psychiatric hospitalizations are negatively related. The doses of medication (antipsychotics or antidepressants) show no significant relationship to clinical improvement. © 2017 The British Psychological Society.

To analyse the psychometric properties of the EQ-5D in German stroke survivors undergoing neurological rehabilitation. The EQ-5D, the Hospital Anxiety and Depression Scale (HADS) and the Stroke Impact Scale (SIS) were completed before (210 subjects) and after (183 subjects) a patient education programme in seven rehabilitation clinics in Bavaria, Germany. A postal follow-up was conducted after 6 months. Acceptance, validity, reliability and responsiveness of the EQ-5D were tested. The SIS subscales were used as external anchors to classify the patients into change groups between the measurements. The proportion of missing answers ranged from 4.7 to 8.6%. Between 16 and 19% reported no problems in any EQ-5D dimension. At baseline, correlations between EQ-5D index and the SIS subscales ranged from 0.15 (communication) to 0.60 (mobility). Correlations with the EQ VAS were slightly smaller. All scores were reliable in test-retest with intraclass correlations ranging from 0.67 to 0.81. EQ-5D index and EQ VAS were consistently responsive only to improvements in health, showing small- to medium effect sizes (0.27-0.42). The EQ-5D has shown reasonable validity, reliability and, more limited, responsiveness in stroke patients with mild to moderate limitations of functional status, allowing it to be used in clinical trials in rehabilitation.

2011-01-01

Objective: This study aimed to provide an overview of the development, content, feasibility, and effectiveness of existing orientation and mobility training programmes in the use of the identification cane. Data sources: A systematic bibliographic database search in PubMed, PsychInfo, ERIC, CINAHL and the Cochrane Library was performed, in combination with the expert consultation (n = 42; orientation and mobility experts), and hand-searching of reference lists. Review methods: Selection criteria included a description of the development, the content, the feasibility, or the effectiveness of orientation and mobility training in the use of the identification cane. Two reviewers independently agreed on eligibility and methodological quality. A narrative/qualitative data analysis method was applied to extract data from obtained documents. Results: The sensitive database search and hand-searching of reference lists revealed 248 potentially relevant abstracts. None met the eligibility criteria. Expert consultation resulted in the inclusion of six documents in which the information presented on the orientation and mobility training in the use of the identification cane was incomplete and of low methodological quality. Conclusion: Our review of the literature showed a lack of well-described protocols and studies on orientation and mobility training in identification cane use. PMID:21795405

To develop a mHealth programme, entitled 'Care4Heart' for the working population in Singapore and thereafter examine its feasibility and effectiveness in increasing the awareness and knowledge of coronary heart disease and improving their heart-related lifestyle. Teaching and encouraging the working population to adopt a healthier lifestyle could result in preventing and/or decreasing the incidence of coronary heart disease among this population. The use of mobile application (app) is the next logical wave of healthcare support tools to prevent and manage chronic diseases like coronary heart disease. A quasi-experimental longitudinal study design. The study will be conducted in a tertiary university in Singapore. A non-probability, quota sampling of 200 participants will be recruited including 100 academic and research staff, 50 administrative staff and 50 support staff and business owners. Once consent is obtained, the newly developed mobile app will be installed onto the participants' smartphones and a well-trained research assistant will brief the participant on the use of the app. The main outcomes will be measured using the survey questionnaires: Awareness of coronary heart disease, Heart Disease Fact Questionnaire-2, Behavioural Risk Factor Surveillance System and Perceived Stress Scale. Data will be collected at baseline and at the 4th week and 6th month thereafter. If this project is successful, Care4Heart - a mHealth and novel prevention educational programme for the working population in Singapore - can be used to promote knowledge and positive heart-related lifestyle changes to prevent coronary heart disease. © 2015 John Wiley & Sons Ltd.

Differences in antiretroviral scale up in three South African provinces: the role of implementation management

PubMed Central

2010-01-01

Background South Africa’s antiretroviral programme is governed by defined national plans, establishing treatment targets and providing funding through ring-fenced conditional grants. However, in terms of the country’s quasi-federal constitution, provincial governments bear the main responsibility for provision of health care, and have a certain amount of autonomy and therefore choice in the way their HIV/AIDS programmes are implemented. Methods The paper is a comparative case study of the early management of ART scale up in three South African provincial governments – Western Cape, Gauteng and Free State – focusing on both operational and strategic dimensions. Drawing on surveys of models of ART care and analyses of the policy process conducted in the three provinces between 2005 and 2007, as well as a considerable body of grey and indexed literature on ART scale up in South Africa, it draws links between implementation processes and variations in provincial ART coverage (low, medium and high) achieved in the three provinces. Results While they adopted similar chronic disease care approaches, the provinces differed with respect to political and managerial leadership of the programme, programme design, the balance between central standardisation and local flexibility, the effectiveness of monitoring and evaluation systems, and the nature and extent of external support and programme partnerships. Conclusions This case study points to the importance of sub-national programme processes and the influence of factors other than financing or human resource capacity, in understanding intervention scale up.

Bungoma District Hospital Laboratory (BDHL), which supports a 200-bed referral facility, began its Strengthening Laboratory Management Toward Accreditation (SLMTA) journey in 2011 together with eight other laboratories in the second round of SLMTA rollout in Kenya. To describe how the SLMTA programme and enhanced quality interventions changed the culture and management style at BDHL and instilled a quality system designed to sustain progress for years to come. SLMTA implementation followed the standard three-workshop series, mentorship site visits and audits. In order to build sustainability of progress, BDHL integrated quality improvement processes into its daily operations. The lab undertook a process of changing its internal culture to align all hospital stakeholders - including upper management, clinicians, laboratory staff and maintenance staff - to the mission of sustainable quality practices at BDHL. After 16 months in the SLMTA programme, BDHL improved from zero stars (38%) to four stars (89%). Over a period of two to three years, external quality assessment results improved from 47% to 87%; staff punctuality increased from 49% to 82%; clinician complaints decreased from 83% to 16; rejection rates decreased from 12% to 3%; and annual equipment repairs decreased from 40 to 15. Twelve months later the laboratory scored three stars (81%) in an external surveillance audit conducted by Kenya Accreditation Service (KENAS). Management buy-in, staff participation, use of progress-monitoring tools and feedback systems, as well as incorporation of improvement processes into routine daily activities, were vital in developing and sustaining a culture of quality improvement.

2016-09-01

A systematic review with meta-analysis was performed to investigate the effect external sensory cued therapy on activities of daily living (ADL) performance that include walking and daily tasks such as dressing for individuals with Parkinson's disease (PD). A detailed computer-aided search of the literature was applied to MEDLINE, Cumulative Index to Nursing and Allied Health Literature, EMBASE and PubMed. Studies investigating the effects of external sensory cued therapy on ADL performance for individuals with PD in all stages of disease progression were collected. Relevant articles were critically reviewed and study results were synthesized by two independent researchers. A data-analysis method was used to extract data from selected articles. A meta-analysis was carried out for all randomized-controlled trials. Six studies with 243 individuals with PD were included in this review. All six studies yielded positive findings in favour of external sensory cues. The meta-analysis showed that external sensory cued therapy improved statistically after treatment (P=0.011) and at follow-up (P<0.001) for ADL performance. The results of this review provided evidence of an improvement in ADL performance in general in individuals with PD. It is recommended that clinicians incorporate external sensory into a training programme focused on improving daily task performance.

Advancements in knowledge of obesity aetiology and mobile phone technology have created the opportunity to develop an electronic tool to predict an infant's risk of childhood obesity. The study aims were to develop and validate equations for the prediction of childhood obesity and integrate them into a mobile phone application (App). Anthropometry and childhood obesity risk data were obtained for 1868 UK-born White or South Asian infants in the Born in Bradford cohort. Logistic regression was used to develop prediction equations (at 6 ± 1.5, 9 ± 1.5 and 12 ± 1.5 months) for risk of childhood obesity (BMI at 2 years >91(st) centile and weight gain from 0-2 years >1 centile band) incorporating sex, birth weight, and weight gain as predictors. The discrimination accuracy of the equations was assessed by the area under the curve (AUC); internal validity by comparing area under the curve to those obtained in bootstrapped samples; and external validity by applying the equations to an external sample. An App was built to incorporate six final equations (two at each age, one of which included maternal BMI). The equations had good discrimination (AUCs 86-91%), with the addition of maternal BMI marginally improving prediction. The AUCs in the bootstrapped and external validation samples were similar to those obtained in the development sample. The App is user-friendly, requires a minimum amount of information, and provides a risk assessment of low, medium, or high accompanied by advice and website links to government recommendations. Prediction equations for risk of childhood obesity have been developed and incorporated into a novel App, thereby providing proof of concept that childhood obesity prediction research can be integrated with advancements in technology.

Geography of intergenerational mobility and child development

Recent research by Chetty and colleagues finds that children’s chances of upward mobility are affected by the communities in which they grow up [Chetty R, Hendren N (2016) Working paper 23002]. However, the developmental pathways through which communities of origin translate into future economic gain are not well understood. In this paper we examine the association between Chetty and Hendren’s county-level measure of intergenerational mobility and children’s cognitive and behavioral development. Focusing on children from low-income families, we find that growing up in a county with high upward mobility is associated with fewer externalizing behavioral problems by age 3 years and with substantial gains in cognitive test scores between ages 3 and 9 years. Growing up in a county with 1 SD better intergenerational mobility accounts for ∼20% of the gap in developmental outcomes between children from low- and high-income families. Collectively, our findings suggest that the developmental processes through which residential contexts promote upward mobility begin early in childhood and involve the enrichment of both cognitive and social-emotional development.

Electro-optical modeling of bulk heterojunction solar cells

Kirchartz, Thomas; Pieters, Bart E.; Taretto, Kurt; Rau, Uwe

2008-11-01

We introduce a model for charge separation in bulk heterojunction solar cells that combines exciton transport to the interface between donor and acceptor phases with the dissociation of the bound electron/hole pair. We implement this model into a standard semiconductor device simulator, thereby creating a convenient method to simulate the optical and electrical characteristics of a bulk heterojunction solar cell with a commercially available program. By taking into account different collection probabilities for the excitons in the polymer and the fullerene, we are able to reproduce absorptance, internal and external quantum efficiency, as well as current/voltage curves of bulk heterojunction solar cells. We further investigate the influence of mobilities of the free excitons as well as the mobilities of the free charge carriers on the performance of bulk heterojunction solar cells. We find that, in general, the highest efficiencies are achieved with the highest mobilities. However, an optimum finite mobility of free charge carriers can result from a large recombination velocity at the contacts. In contrast, Langevin-type of recombination cannot lead to finite optimum mobilities even though this mechanism has a strong dependence on the free carrier mobilities.

Automatic external filling for the ion source gas bottle of a Van de Graaff accelerator

We describe a fully automatic system we developed to fill, from an external gas bottle, the ion source terminal gas storage bottle of a 2 MV Van de Graaff accelerator without depressing the 25 bar insulating gas. The system is based on a programmable automate ordering electropneumatical valves. The only manual operation is the connection of the external gas cylinder. The time needed for a gas change is reduced to typically 15 min (depending on the residual pressure wished for the gas removed from the terminal bottle). To check this system we study the ionic composition of the ion beam delivered by our accelerator after different gas changes. The switching magnet of our accelerator was used to analyse the ionic composition of the accelerated beams in order to verify the degree of elimination of the previous gases in the system.

6 DOF articulated-arm robot and mobile platform: Dynamic modelling as Multibody System and its validation via Experimental Modal Analysis.

Toledo Fuentes, A.; Kipfmueller, M.; José Prieto, M. A.

Mobile manipulators are becoming a key instrument to increase the flexibility in industrial processes. Some of their requirements include handling of objects with different weights and sizes and their “fast” transportation, without jeopardizing production workers and machines. The compensation of forces affecting the system dynamic is therefore needed to avoid unwanted oscillations and tilting by sudden accelerations and decelerations. One general solution may be the implementation of external positioning elements to active stabilize the system. To accomplish the approach, the dynamic behavior of a robotic arm and a mobile platform was investigated to develop the stabilization mechanism using multibody simulations. The methodology used was divided into two phases for each subsystem: their natural frequencies and modal shapes were obtained using experimental modal analyses. Then, based on these experimental results, multibody simulation models (MBS) were set up and its dynamical parameters adjusted. Their modal shapes together with their obtained natural frequencies allowed a quantitative and qualitative analysis. In summary, the MBS models were successfully validated with the real subsystems, with a maximal percentage error of 15%. These models will serve as the basis for future steps in the design of the external actuators and its control strategy using a co-simulation tool.

Automatic and robust extrinsic camera calibration for high-accuracy mobile mapping

NASA Astrophysics Data System (ADS)

2012-10-01

A mobile mapping system (MMS) is the answer of the geoinformation community to the exponentially growing demand for various geospatial data with increasingly higher accuracies and captured by multiple sensors. As the mobile mapping technology is pushed to explore its use for various applications on water, rail, or road, the need emerges to have an external sensor calibration procedure which is portable, fast and easy to perform. This way, sensors can be mounted and demounted depending on the application requirements without the need for time consuming calibration procedures. A new methodology is presented to provide a high quality external calibration of cameras which is automatic, robust and fool proof.The MMS uses an Applanix POSLV420, which is a tightly coupled GPS/INS positioning system. The cameras used are Point Grey color video cameras synchronized with the GPS/INS system. The method uses a portable, standard ranging pole which needs to be positioned on a known ground control point. For calibration a well studied absolute orientation problem needs to be solved. Here, a mutual information based image registration technique is studied for automatic alignment of the ranging pole. Finally, a few benchmarking tests are done under various lighting conditions which proves the methodology's robustness, by showing high absolute stereo measurement accuracies of a few centimeters.

Ethical considerations of mobile phone use by patients in KwaZulu-Natal: Obstacles for mHealth?

mHealth has the potential to facilitate telemedicine services, particularly in the developing world. Concern has been expressed about the confidentiality of health information that is relayed by mobile phone. We examined the habits and practices of mobile phone use by patients in KwaZulu-Natal, South Africa. We conducted a descriptive survey of two patient populations: 137 urban patients attending private practitioners and 139 patients in remote rural areas attending outpatient departments in Government-funded hospitals. The questionnaire covered several domains: demographics, mobile phone use, privacy and confidentiality and future use for health-related matters. Two hundred and seventy-six patients completed the questionnaire. We found that a third of our participants shared their mobile phone with others, 24% lent their phone to others and more than half received health-related messages for other people. Mobile phone theft was common, as was number changing. Thirty-eight percent of the people were not able to afford airtime for more than a week in the past year and 22% of rural patients were unable to keep their phone charged. Mobile phone signal coverage was significantly worse in the rural areas than in urban areas. This study highlights the legal and ethical ramifications that these practices and findings will have on mHealth programmes in our setting. Healthcare providers and regulators will need to consider how patients use and manage their mobile phones when developing services and regulations.

Two studies tested hypotheses about the distinctive psychological consequences of children's patterns of responding to interparental conflict. In Study 1, 174 preschool children (M = 4.0 years) and their mothers participated in a cross-sectional design. In Study 2, 243 preschool children (M = 4.6 years) and their parents participated in 2 annual measurement occasions. Across both studies, multiple informants assessed children's psychological functioning. Guided by the reformulated version of emotional security theory, behavioral observations of children's coping with interparental conflict assessed their tendencies to exhibit 4 patterns based on their function in defusing threat: secure (i.e., efficiently address direct instances of threat), mobilizing (i.e., react to potential threat and social opportunities), dominant (i.e., directly defeat threat), and demobilizing (i.e., reduce salience as a target of hostility). As hypothesized, each profile predicted unique patterns of adjustment. Greater security was associated with lower levels of internalizing and externalizing symptoms and greater social competence, whereas higher dominance was associated with externalizing problems and extraversion. In contrast, mobilizing patterns of reactivity predicted more problems with self-regulation, internalizing symptoms, externalizing difficulties, but also greater extraversion. Finally, higher levels of demobilizing reactivity were linked with greater internalizing problems and lower extraversion but also better self-regulation.

Schistosomiasis control programme in The People's Republic of China had promoted the mass mobilization of health education in various forms, such as films, drama, traditional opera, poems, slogans, posters, exhibits. This paper is trying to review the impacts of those forms on different endemic settings and targeted populations. In the future, health education and health promotion will still be the effective strategy and one of the interventions in the national control programme for schistosomiasis and other infectious diseases, even in the pre- or posttransmission stages. With the social and economic development and improvement of people's living standard, it is necessary to establish a sustainable mechanism, in combination of health education with health guarantee of improving the quality of life, improving the production and living conditions, changing the unhealthy production methods and lifestyle of the residents in the endemic areas, in order to reach the goal of schistosomiasis elimination in The People's Republic of China.

Security mechanism based on Hospital Authentication Server for secure application of implantable medical devices.

PubMed

Park, Chang-Seop

2014-01-01

After two recent security attacks against implantable medical devices (IMDs) have been reported, the privacy and security risks of IMDs have been widely recognized in the medical device market and research community, since the malfunctioning of IMDs might endanger the patient's life. During the last few years, a lot of researches have been carried out to address the security-related issues of IMDs, including privacy, safety, and accessibility issues. A physician accesses IMD through an external device called a programmer, for diagnosis and treatment. Hence, cryptographic key management between IMD and programmer is important to enforce a strict access control. In this paper, a new security architecture for the security of IMDs is proposed, based on a 3-Tier security model, where the programmer interacts with a Hospital Authentication Server, to get permissions to access IMDs. The proposed security architecture greatly simplifies the key management between IMDs and programmers. Also proposed is a security mechanism to guarantee the authenticity of the patient data collected from IMD and the nonrepudiation of the physician's treatment based on it. The proposed architecture and mechanism are analyzed and compared with several previous works, in terms of security and performance.

Innovative and effective smoking cessation interventions are required to appeal to those who are not accessing traditional cessation services. Mobile phones are widely used and are now well-integrated into the daily lives of many, particularly young adults. Mobile phones are a potential medium for the delivery of health programmes such as smoking cessation. To determine whether mobile phone-based interventions are effective at helping people who smoke, to quit. For the most recent update, we searched the Cochrane Tobacco Addiction Group Specialised Register in May 2012. We also searched UK Clinical Research Network Portfolio for current projects in the UK and the ClinicalTrials register for on-going or recently completed studies. We searched through the reference lists of identified studies and attempted to contact the authors of ongoing studies, with no restrictions placed on language or publication date. We included randomized or quasi-randomized trials. Participants were smokers of any age who wanted to quit. Studies were those examining any type of mobile phone-based intervention. This included any intervention aimed at mobile phone users, based around delivery via mobile phone, and using any functions or applications that can be used or sent via a mobile phone. Information on risk of bias and methodological details was extracted using a standardised form. Participants who dropped out of the trials or were lost to follow-up were considered to be smoking. We calculated risk ratios (RR) for each included study. Meta-analysis of the included studies was undertaken using the Mantel-Haenszel fixed-effect method. Where meta-analysis was not possible, summary and descriptive statistics are presented. Five studies with at least six month cessation outcomes were included in this review. Three studies involve a purely text messaging intervention that has been adapted over the course of these three studies for different populations and contexts. One study is a multi-arm study of a text messaging intervention and an internet QuitCoach separately and in combination. The final study involves a video messaging intervention delivered via the mobile phone. When all five studies were pooled, mobile phone interventions were shown to increase the long term quit rates compared with control programmes (RR 1.71, 95% CI 1.47 to 1.99, over 9000 participants), using a definition of abstinence of no smoking at six months since quit day but allowing up to three lapses or up to five cigarettes. Statistical heterogeneity was substantial as indicated by the I² statistic (I² = 79%), but as all included studies were similar in design, intervention and primary outcome measure, we have presented the meta-analysis in this review. The current evidence shows a benefit of mobile phone-based smoking cessation interventions on long-term outcomes, though results were heterogenous with findings from three of five included studies crossing the line of no effect. The studies included were predominantly of text messaging interventions. More research is required into other forms of mobile phone-based interventions for smoking cessation, other contexts such as low income countries, and cost-effectiveness.

Transcendence, ethics, and Mobil Oil: a rhetorical investigation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Williamson, L.A.

1982-01-01

Since 1970 the Mobil Oil Corporation has been widely recognized as the self-appointed champion of corporate America's right to advocate. Corporate advocacy, as distinguished from other forms of external corporate communication, is concerned with the modification of corporate images and those social and political issues directly linked to the well-being of the corporation. Kenneth Burke's theory of transcendence serves as the central critical referent in the critique of Mobil's advocacy. By evoking elaborate transcendent frames of reference, Mobil seeks to identify its actions with higher syntheses that allow them to transcend the guilt produced by identifications with lesser orders. Mobilmore » evokes two ultimate frames which are recurrent in their transcendent identifications: American energy independence and freedom of expression. In the latter part of this investigation, Sidney Hook's ethics of controversy was offered as an ethical referent. Two levels of analysis were conducted: first, three major types of arguments against Mobil's advocacy were evaluated; second, Mobil's discourse was evaluated. The conclusion was reached that Mobil's advocacy is largely an ethical form of American democratic discourse. In the final section of this investigation, the heuristic values of this critique were discussed.« less

We aimed to implement the European Resuscitation Council (ERC) basic life support (BLS) and automated external defibrillator (AED) course as a mandatory peer-led training programme for medical students and to evaluate the satisfaction with this course. Medical students certified as ERC BLS/AED instructors were recruited as student trainers and organizers of the course, which was included as a mandatory part of the curriculum for second-year medical students before first clinical rotation. After each course, questionnaires were distributed to evaluate the peer-led training programme. In total, 146 students were trained and assessed. The quality of the course was rated as 9.4±0.8 (10-point scale, 10 being best), and the majority (95%) felt better prepared for their clinical rotation. Implementation of the ERC BLS/AED course as a mandatory peer-led training programme for medical students is feasible. The course has been very well accepted and the students feel better prepared for their first clinical rotation.

In the Aditya Tokamak, one of primary requirement for plasma generation is to feed the required quantity of the fuel gas prior to plasma shot. Gas feed system mainly consists of piezoelectric gas leak valve and gas reservoir. The Hydrogen gas is prior to 300ms loop voltage for the duration of 4 msec to 7 msec. Gas is puffed during the shot for required plasma parameters and to increase plasma density using the same system. The valve is controlled by either continuous voltage or pulses of different width, amplitude and delay with respect to loop voltage. These voltage pulses are normally applied through standard pulse generator. The standard pulse generator is replaced by micro controller based in housed developed programmable pulse generator system consists of in built power supply, BNC input for external trigger, BNC output and serial interface. This programmable pulse generator is successfully tested and is in operation for gas puffing during ADITYA Tokamak experiments. The paper discusses the design and development aspect of the system.

XPI: The Xanadu Parameter Interface

1992-01-01

XPI is a table driven parameter interface which greatly simplifies both command driven programs such as BROWSE and XIMAGE as well as stand alone single-task programs. It moves all of the syntax and semantic parsing of commands and parameters out of the users code into common code and externally defined tables. This allows the programmer to concentrate on writing the code unique to the application rather than reinventing the user interface and for external graphical interfaces to interface with no changes to the command driven program. XPI also includes a compatibility library which allows programs written using the IRAF host interface (Mandel and Roll) to use XPI in place of the IRAF host interface.

1995-01-01

The EUTELTRACS two-way Mobile Satellite Messaging and Automatic Satellite Position Reporting (ASPR) service is Europe's first commercially operated Mobile Satellite Service. It was introduced by the European Telecommunications Satellite Organization (EUTELSAT) for commercial service in 1991. The system is based on a centralized network architecture organized around a single hub station operated by EUTELSAT. Initially the system was designed with a close user group architecture enabling a mobile user to communicate exclusively with its own headquarters. This paper describes the new applications (design and tests prior to their introduction into service) especially developed for the European market and particularly the Double Hop Services opening the system to authorized external entities. In addition, the European Commission (EC) pilot demonstrations in which the EUTELTRACS system is involved are described.

OLED technology has matured sufficiently to consider it a realistic candidate for military display applications. Manufacturing sources are transitioning from an early developer to a business focused and often rationalised supply base that already has a sustainable business model. New commercial products, with a growing list of applications are slowly swelling the list of available OLED display components that can be considered for military requirements. This paper describes an exploratory application of OLED technology to the Towed Artillery Digitisation (TAD) programme. The Gunners Display function in this system endures the most difficult environment available in Army programmes. By replicating the Gunners Display, we have confirmed that OLED technology is compatible with and technically almost ready for rugged military applications using newly available commercial sources.

Brownian escape and force-driven transport through entropic barriers: Particle size effect.

PubMed

Cheng, Kuang-Ling; Sheng, Yu-Jane; Tsao, Heng-Kwong

2008-11-14

Brownian escape from a spherical cavity through small holes and force-driven transport through periodic spherical cavities for finite-size particles have been investigated by Brownian dynamic simulations and scaling analysis. The mean first passage time and force-driven mobility are obtained as a function of particle diameter a, hole radius R(H), cavity radius R(C), and external field strength. In the absence of external field, the escape rate is proportional to the exit effect, (R(H)R(C))(1-a2R(H))(32). In weak fields, Brownian diffusion is still dominant and the migration is controlled by the exit effect. Therefore, smaller particles migrate faster than larger ones. In this limit the relation between Brownian escape and force-driven transport can be established by the generalized Einstein-Smoluchowski relation. As the field strength is strong enough, the mobility becomes field dependent and grows with increasing field strength. As a result, the size selectivity diminishes.

Conduction Electrohydrodynamics with Mobile Electrodes: A Novel Actuation System for Untethered Robots

PubMed Central

Shigemune, Hiroki; Cianchetti, Matteo; Laschi, Cecilia

2017-01-01

Electrohydrodynamics (EHD) refers to the direct conversion of electrical energy into mechanical energy of a fluid. Through the use of mobile electrodes, this principle is exploited in a novel fashion for designing and testing a millimeter‐scale untethered robot, which is powered harvesting the energy from an external electric field. The robot is designed as an inverted sail‐boat, with the thrust generated on the sail submerged in the liquid. The diffusion constant of the robot is experimentally computed, proving that its movement is not driven by thermal fluctuations, and then its kinematic and dynamic responses are characterized for different applied voltages. The results show the feasibility of using EHD with mobile electrodes for powering untethered robots and provide new evidences for the further development of this actuation system for both mobile robots and compliant actuators in soft robotics.

Long-Range Interactions Restrict Water Transport in Pyrophyllite Interlayers

PubMed Central

Zarzycki, Piotr; Gilbert, Benjamin

2016-01-01

Water diffusion within smectite clay interlayers is reduced by confinement and hence is highly determined by the interlayer spacings that are adopted during swelling. However, a molecular understanding of the short- and long-range forces governing interlayer water structure and dynamics is lacking. Using molecular dynamics simulations of water intercalated between pyrophyllite (smectite prototype) layers we provide a detailed picture of the variation of interlayered water mobility accompanying smectite expansion. Subtle changes in hydrogen bond network structure cause significant changes in water mobility that is greater for stable hydration states and reduced for intermediate separations. By studying pyrophyllite with and without external water we reveal that long-range electrostatic forces apply a restraining effect upon interlayer water mobility. Our findings are relevant for broad range of confining nanostructures with walls thin enough to permit long-range interactions that could affect the mobility of confined solvent molecules and solute species.

With smartphone sales currently surpassing laptop sales, it is hard not to think that these devices will have a place in the classroom. More specifically, with little to no monetary investment, classroom-centric mobile applications have the ability to suit the needs of teachers. Previously, programming such an item was a daunting task to the classroom teacher. But now, through the use of online visual tools, anyone has the ability to generate a mobile application to suit individual classroom needs. The "MY NASA DATA" (MND) project has begun work on such an application. Using online tools that are directed at the non-programmer, the team has developed two usable mobile applications ("apps") that fit right into the science classroom. The two apps generated include a cloud dichotomous key for cloud identification in the field, and an atmospheric science glossary to help with standardized testing key vocabulary and classroom assignments. Through the use of free online tools, teachers and students now have the ability to customize mobile applications to meet their individual needs. As an extension of the mobile applications, the MND team is planning web-based application programming interfaces (API's) that will be generated from data that is currently included in the MND Live Access Server. This will allow teachers and students to choose data sets that they want to include in the mobile application without having to populate the API themselves. Through the use of easy to understand online mobile app tutorials and MND data sets, teachers will have the ability to generate unit-specific mobile applications to further engage and empower students in the science classroom.

Guideline adherence in physical therapy is far from optimal, which has consequences for the effectiveness and efficiency of physical therapy care. Programmes to enhance guideline adherence have, so far, been relatively ineffective. We systematically developed a theory-based Quality Improvement in Physical Therapy (QUIP) programme aimed at the individual performance level (practicing physiotherapists; PTs) and the practice organization level (practice quality manager; PQM). The aim of the study was to pilot test the multilevel QUIP programme's effectiveness and the fidelity, acceptability and feasibility of its implementation. A one-group, pre-test, post-test pilot study (N = 8 practices; N = 32 PTs, 8 of whom were also PQMs) done between September and December 2009. Guideline adherence was measured using clinical vignettes that addressed 12 quality indicators reflecting the guidelines' main recommendations. Determinants of adherence were measured using quantitative methods (questionnaires). Delivery of the programme and management changes were assessed using qualitative methods (observations, group interviews, and document analyses). Changes in adherence and determinants were tested in the paired samples T-tests and expressed in effect sizes (Cohen's d). Overall adherence did not change (3.1%; p = .138). Adherence to three quality indicators improved (8%, 24%, 43%; .000 ≤ p ≤ .023). Adherence to one quality indicator decreased (-15.7%; p = .004). Scores on various determinants of individual performance improved and favourable changes at practice organizational level were observed. Improvements were associated with the programme's multilevel approach, collective goal setting, and the application of self-regulation; unfavourable findings with programme deficits. The one-group pre-test post-test design limits the internal validity of the study, the self-selected sample its external validity. The QUIP programme has the potential to change physical therapy practice but needs considerable revision to induce the ongoing quality improvement process that is required to optimize overall guideline adherence. To assess its value, the programme needs to be tested in a randomized controlled trial.

In Lao PDR, investment by the Global Fund to Fight AIDS, Tuberculosis and Malaria has played an important role in scaling up the response to HIV and tuberculosis (TB). As part of a series of case studies on how Global Fund-supported programmes interact with national health systems, we assessed the nature and extent of integration of the Global Fund portfolios within the national HIV and TB programmes, the integration of the HIV and TB programmes within the general health system, and system-wide effects of Global Fund support in Lao PDR. The study relied on a literature review and 35 interviews with key stakeholders using the Systemic Rapid Assessment Toolkit and thematic analysis. In Lao PDR, the HIV and TB programmes remain vertical and mostly weakly integrated with the general health system. However, Global Fund investments have extended the network of facilities delivering care at local level, resulting in greater integration with primary care and improved access for patients, particularly for TB. For HIV, as the prevalence remains low, services primarily target high-risk groups in urban areas. Less integrated functions include procurement and drug supply, and monitoring and evaluation. HIV and TB programmes are only starting to coordinate with each other. Global Fund-supported activities are generally integrated within the national disease programmes, except for monitoring and evaluation. Synergies of Global Fund support with the health system include improved access to services, institutional strengthening and capacity building, improved family planning (with wider condom distribution through HIV/AIDS social marketing programmes), and the delivery of add-on interventions, such as vaccinations and health education, alongside Global Fund-supported interventions at community level. Unintended consequences concern the lack of alignment between national stated priorities (maternal and child health) and the strong focus of external partners, such as the Global Fund, on financing communicable disease programmes.

The physical activity level of older adults with intellectual disabilities (ID) is extremely low, and their fitness levels are far beneath accepted norms for older people with normal intelligence and comparable with frail older people. A physical activity programme, including an education programme, was developed for older adults with ID using behaviour change techniques. The programme aimed at improving or maintaining adequate levels of physical activity (primary outcome measure) and motor fitness, cardio respiratory fitness, morphologic and metabolic fitness, activities of daily living, cognitive functioning and depressive symptoms (secondary outcome measures). The programme's efficacy was evaluated in a cluster-randomised clinical trial among people aged 43 years and over with mild-moderate levels of ID. Five day-activity centres were randomised to the participation group. In these centres, 81 older adults participated in groups of 8 to 10 in the programme, three times a week during 8 months. The programme was executed by physical activity instructors and staff of day-activity centres. Five other day-activity centres were randomised to the control group; 70 older adults in these centres received care as usual. The generalised linear model with mixed effects was used to test the programme's effectiveness. Significant effects were found on physical activity, muscle strength, systolic and diastolic blood pressure, serum cholesterol level and cognitive functioning, in favour of the programme's participants. No significant improvements were found on balance, serum glucose, weight, waist circumference, walking speed, mobility, depression or instrumental activities of daily living. The physical activity and fitness programme has established small but significant effects in this sample, but generalising the findings to other settings is difficult due to significant participant dropout. Implementation of evidence-based physical activity programmes among older adults with ID is recommended. Further research is needed to investigate the effectiveness of physical activity on daily life functioning and the development on chronic diseases in the long run. © 2016 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Social media and mobile applications that allow people to work anywhere are changing the way people can contribute and collaborate. We sought to determine the feasibility of using mobile workforce technology to validate the locations of automated external defibrillators (AEDs), an emergency public health resource. We piloted the use of a mobile workforce application, to verify the location of 40 AEDs in Philadelphia county. AEDs were pre-identified in public locations for baseline data. The task of locating AEDs was posted online for a mobile workforce from October 2011 to January 2012. Participants were required to submit a mobile phone photo of AEDs and descriptions of the location. Thirty-five of the 40 AEDs were identified within the study period. Most, 91% (32/35) of the submitted AED photo information was confirmed project baseline data. Participants also provided additional data such as business hours and other nearby AEDs. It is feasible to engage a mobile workforce to complete health research-related tasks. Participants were able to validate information about emergency public health resources.

Introduction Generalised anxiety disorder (GAD) and subclinical GAD are highly prevalent in primary care. Unmanaged anxiety worsens quality of life in patients seen in primary care practices and leads to increased medical utilisation and costs. Programmes that teach patients cognitive–behavioural therapy (CBT) techniques have been shown to improve anxiety and to prevent the evolution of anxiety symptoms to disorders, but access and engagement have hampered integration of CBT into medical settings. Methods and analysis This pragmatic study takes place in University of Pittsburgh Medical Center primary care practices to evaluate a coach-supported mobile cognitive– behavioural programme (Lantern) on anxiety symptoms and quality of life. Clinics were non-randomly assigned to either enhanced treatment as usual or Lantern. All clinics provide electronic screening for anxiety and, within clinics assigned to Lantern, patients meeting a threshold level of mild anxiety (ie, >5 on Generalised Anxiety Disorder 7-Item Questionnaire (GAD-7)) are referred to Lantern. The first study phase is aimed at establishing feasibility, acceptability and effectiveness. The second phase focuses on long-term impact on psychosocial outcomes, healthcare utilisation and clinic/provider adoption/sustainable implementation using a propensity score matched parallel group study design. Primary outcomes are changes in anxiety symptoms (GAD-7) and quality of life (Short-Form Health Survey) between baseline and 6-month follow-ups, comparing control and intervention. Secondary outcomes include provider and patient satisfaction, patient engagement, durability of changes in anxiety symptoms and quality of life over 12 months and the impact of Lantern on healthcare utilisation over 12 months. Patients from control sites will be matched to the patients who use the mobile app. Ethics and dissemination Ethics and human subject research approval were obtained. A data safety monitoring board is overseeing trial data and ethics. Results will be communicated to participating primary care practices, published and presented at clinical and scientific conferences. Trial registration number NCT03035019. PMID:29331971

2017-02-06

Purpose This study sought to identify the barriers and enablers to leadership enactment in academic health-care settings. Design/methodology/approach Semi-structured interviews ( n = 77) with programme stakeholders (medical school trainees, university leaders, clinical leaders, medical scientists and directors external to the medical school) were conducted, and the responses content-analysed. Findings Both contextual and individual factors were identified as playing a role in affecting academic health leadership enactment that has an impact on programme development, success and maintenance. Contextual factors included sufficient resources allocated to the programme, opportunities for learners to practise leadership skills, a competent team around the leader once that person is in place, clear expectations for the leader and a culture that fosters open communication. Contextual barriers included highly bureaucratic structures, fear-of-failure and non-trusting cultures and inappropriate performance systems. Programmes were advised to select participants based on self-awareness, strong communication skills and an innovative thinking style. Filling specific knowledge and skill gaps, particularly for those not trained in medical school, was viewed as essential. Ineffective decision-making styles and tendencies to get involved in day-to-day activities were barriers to the development of academic health leaders. Originality/value Programmes designed to develop academic health-care leaders will be most effective if they develop leadership at all levels; ensure that the organisation's culture, structure and processes reinforce positive leadership practices; and recognise the critical role of teams in supporting its leaders.

Since 1990 the WHO Global Tuberculosis Programme (GTB) has promoted the revision of national tuberculosis programmes to strengthen the focus on directly observed treatment, short-course (DOTS) and close monitoring of treatment outcomes. GTB has encouraged in-depth evaluation of activities through a comprehensive programme review. Over the period 1990-95, WHO supported 12 such programme reviews. The criteria for selection were as follows: large population (Bangladesh, Brazil, China, Ethiopia, India, Indonesia, Mexico, and Thailand); good prospects of developing a model programme for a region (Nepal, Zimbabwe); or at advanced stage of implementation of a model programme for a region (Guinea, Peru). The estimated combined incidence of smear-positive pulmonary tuberculosis was 82 per 100,000 population, about 43% of the global incidence. The prevalence of infection with human immunodeficiency virus (HIV) was variable, being very high in Ethiopia and Zimbabwe, but negligible in Bangladesh, China, Nepal and Peru. The programme reviews were conducted by teams of 15-35 experts representing a wide range of national and external institutions. After a 2-3-month preparatory period, the conduct of the review usually lasted 2-3 weeks, including a first phase of meetings with authorities and review of documents, a second phase for field visits, and a third phase of discussion of findings and recommendations. The main lessons learned from the programme reviews were as follows: programme review is a useful tool to secure government commitment, reorient the tuberculosis control policies and replan the activities on solid grounds; the involvement of public health and academic institutions, cooperating agencies, and nongovernmental organizations secured a broad support to the new policies; programme success is linked to a centralized direction which supports a decentralized implementation through the primary health care services; monitoring and evaluation of case management functions well if it is based on the right classification of cases and quarterly reports on cohorts of patients; a comprehensive programme review should include teaching about tuberculosis in medical, nursing, and laboratory workers' schools; good quality diagnosis and treatment are the essential requirements for expanding a programme beyond the pilot testing; and control targets cannot be achieved if private and social security patients are left outside the programme scope. The methodology of comprehensive programme review should be recommended to all countries which require programme reorientation; it is also appropriate for carrying out evaluations at 4-5-year intervals in countries that are implementing the correct tuberculosis control policies.

Community-based service delivery is vital to the effectiveness, affordability and sustainability of vector control generally, and to labour-intensive larval source management (LSM) programmes in particular. The institutional evolution of a city-level, community-based LSM programme over 14 years in urban Dar es Salaam, Tanzania, illustrates how operational research projects can contribute to public health governance and to the establishment of sustainable service delivery programmes. Implementation, management and governance of this LSM programme is framed within a nested set of spatially-defined relationships between mosquitoes, residents, government and research institutions that build upward from neighbourhood to city and national scales. The clear hierarchical structure associated with vertical, centralized management of decentralized, community-based service delivery, as well as increasingly clear differentiation of partner roles and responsibilities across several spatial scales, contributed to the evolution and subsequent growth of the programme. The UMCP was based on the principle of an integrated operational research project that evolved over time as the City Council gradually took more responsibility for management. The central role of Dar es Salaam's City Council in coordinating LSM implementation enabled that flexibility; the institutionalization of management and planning in local administrative structures enhanced community-mobilization and funding possibilities at national and international levels. Ultimately, the high degree of program ownership by the City Council and three municipalities, coupled with catalytic donor funding and technical support from expert overseas partners have enabled establishment of a sustainable, internally-funded programme implemented by the National Ministry of Health and Social Welfare and supported by national research and training institutes.

Objective To find consensus on appropriate and feasible structure, process and outcome indicators for the evaluation of in-hospital geriatric co-management programmes. Design An international two-round Delphi study based on a systematic literature review (searching databases, reference lists, prospective citations and trial registers). Setting Western Europe and the USA. Participants Thirty-three people with at least 2 years of clinical experience in geriatric co-management were recruited. Twenty-eight experts (16 from the USA and 12 from Europe) participated in both Delphi rounds (85% response rate). Measures Participants rated the indicators on a nine-point scale for their (1) appropriateness and (2) feasibility to use the indicator for the evaluation of geriatric co-management programmes. Indicators were considered appropriate and feasible based on a median score of seven or higher. Consensus was based on the level of agreement using the RAND/UCLA Appropriateness Method. Results In the first round containing 37 indicators, there was consensus on 14 indicators. In the second round containing 44 indicators, there was consensus on 31 indicators (structure=8, process=7, outcome=16). Experts indicated that co-management should start within 24 hours of hospital admission using defined criteria for selecting appropriate patients. Programmes should focus on the prevention and management of geriatric syndromes and complications. Key areas for comprehensive geriatric assessment included cognition/delirium, functionality/mobility, falls, pain, medication and pressure ulcers. Key outcomes for evaluating the programme included length of stay, time to surgery and the incidence of complications. Conclusion The indicators can be used to assess the performance of geriatric co-management programmes and identify areas for improvement. Furthermore, the indicators can be used to monitor the implementation and effect of these programmes. PMID:29549210

Mainstreaming nutrition into maternal and child health programmes: scaling up of exclusive breastfeeding.

2008-04-01

Interventions to promote exclusive breastfeeding have been estimated to have the potential to prevent 13% of all under-5 deaths in developing countries and are the single most important preventive intervention against child mortality. According to World Health Organization and United Nations Children Funds (UNICEF), only 39% infants are exclusively breastfed for less than 4 months. This review examines programme efforts to scale up exclusive breastfeeding in different countries and draws lesson for successful scale-up. Opportunities and challenges in scaling up of exclusive breastfeeding into Maternal and Child Health programmes are identified. The key processes required for exclusive breastfeeding scale-up are: (1) an evidence-based policy and science-driven technical guidelines; and (2) an implementation strategy and plan for achieving high exclusive breastfeeding rates in all strata of society, on a sustainable basis. Factors related to success include political will, strong advocacy, enabling policies, well-defined short- and long-term programme strategy, sustained financial support, clear definition of roles of multiple stakeholders and emphasis on delivery at the community level. Effective use of antenatal, birth and post-natal contacts at homes and through community mobilization efforts is emphasized. Formative research to ensure appropriate intervention design and delivery is critical particularly in areas with high HIV prevalence. Strong communication strategy and support, quality trainers and training contributed significantly to programme success. Monitoring and evaluation with feedback systems that allow for periodic programme corrections and continued innovation are central to very high coverage. Legal framework must make it possible for mothers to exclusively breastfeed for at least 4 months. Sustained programme efforts are critical to achieve high coverage and this requires strong national- and state-level leadership.

Motivating consumers for National Programme on Immunization (NPI) and Oral Rehydration Therapy (ORT) in Nigeria.

Ekerete, P P

1997-01-01

The Expanded Programme on Immunization (EPI) (changed to National Programme on Immunization (NPI) in 1996) and Oral Rehydration Therapy (ORT) were launched in Nigeria in 1979. The goal of EPI was Universal Childhood Immunization (UCI) 1990, that is, to vaccinate 80% of all children age 0-2 years by 1990, and 80% of all pregnant women were also expected to be vaccinated with Tetanus Toxoid Vaccine. The Oral Rehydration Therapy was designed to teach parents with children age 0-5 years how to prepare and use a salt-sugar solution to rehydrate children dehydrated by diarrhoea. Nigeria set up Partners-in-Health to mobilize and motivate mothers to accept the programme. In 1990 a National coverage survey was conducted to assess the level of attainment. The results show that some states were able to reach the target and some were not. It therefore became necessary to evaluate the contribution of those promotional elements adopted by Partners-in-Health to motivate mothers to accept the programme. The respondents were therefore asked to state the degree to which these elements motivated them to accept the programme. The data were collected and processed through a Likert rating scale and t-test procedure for test of significance between two sample means. The study revealed that some elements motivated mothers very strongly, others strongly, and most moderately or low, with health workers as major sources of motivation. The study also revealed that health workers alone can not sufficiently motivate mothers without the help of religious leaders, traditional leaders and mass media, etc. It was therefore recommended that health workers should be intensively used along with other promotional elements to promote the NPI/ORT programme in Nigeria.

Cognitive impairments following brain injury, including difficulty with problem solving, can pose significant barriers to successful community reintegration. Problem-solving strategy training is well-supported in the cognitive rehabilitation literature. However, limitations in insurance reimbursement have resulted in fewer services to train such skills to mastery and to support generalization of those skills into everyday environments. The purpose of this project was to develop and evaluate an integrated, web-based programme, ProSolv, which uses a small number of coaching sessions to support problem solving in everyday life following brain injury. We used participatory action research to guide the iterative development, usability testing, and within-subject pilot testing of the ProSolv programme. The finalized programme was then evaluated in a between-subjects group study and a non-experimental single case study. Results were mixed across studies. Participants demonstrated that it was feasible to learn and use the ProSolv programme for support in problem solving. They highly recommended the programme to others and singled out the importance of the coach. Limitations in app design were cited as a major reason for infrequent use of the app outside of coaching sessions. Results provide mixed evidence regarding the utility of web-based mobile apps, such as ProSolv to support problem solving following brain injury. Implications for Rehabilitation People with cognitive impairments following brain injury often struggle with problem solving in everyday contexts. Research supports problem solving skills training following brain injury. Assistive technology for cognition (smartphones, selected apps) offers a means of supporting problem solving for this population. This project demonstrated the feasibility of a web-based programme to address this need.

Multiple external ventricular drain (EVD) simulators have been created, yet their cost, bulky size, and nonreusable components limit their accessibility to residency programs. To create and validate an animated EVD simulator that is accessible on a mobile device. We developed a mobile-based EVD simulator that is compatible with iOS (Apple Inc., Cupertino, California) and Android-based devices (Google, Mountain View, California) and can be downloaded from the Apple App and Google Play Store. Our simulator consists of a learn mode, which teaches users the procedure, and a test mode, which assesses users' procedural knowledge. Twenty-eight participants, who were divided into expert and novice categories, completed the simulator in test mode and answered a postmodule survey. This was graded using a 5-point Likert scale, with 5 representing the highest score. Using the survey results, we assessed the module's face and content validity, whereas construct validity was evaluated by comparing the expert and novice test scores. Participants rated individual survey questions pertaining to face and content validity a median score of 4 out of 5. When comparing test scores, generated by the participants completing the test mode, the experts scored higher than the novices (mean, 71.5; 95% confidence interval, 69.2 to 73.8 vs mean, 48; 95% confidence interval, 44.2 to 51.6; P < .001). We created a mobile-based EVD simulator that is inexpensive, reusable, and accessible. Our results demonstrate that this simulator is face, content, and construct valid.

Patient choice and mobility in the UK health system: internal and external markets.

PubMed

Dusheiko, Mark

2014-01-01

The National Health Service (NHS) has been the body of the health care system in the United Kingdom (UK) for over 60 years and has sought to provide the population with a high quality service free of user charges for most services. The information age has seen the NHS rapidly transformed from a socialist, centrally planned and publicly provided system to a more market based system orientated towards patients as consumers. The forces of globalization have provided patients in the UK with greater choice in their health care provision, with NHS treatment now offered from any public or approved private provider and the possibility of treatment anywhere in the European Economic Area (EEA) or possibly further. The financial crisis, a large government deficit and austerity public spending policies have imposed a tight budget constraint on the NHS at a time of increasing demand for health care and population pressure. Hence, further rationing of care could imply that patients are incentivised to seek private treatment outside the constraints of the NHS, where the possibility of much greater choice exists in an increasingly globally competitive health care market. This chapter examines the evidence on the response of patients to the possibilities of increased choice and mobility within the internal NHS and external overseas health care markets. It also considers the relationships between patient mobility, health care provision and health policy. Patients are more mobile and willing to travel further to obtain better care outcomes and value for money, but are exposed to greater risk.

The three-dimensional distribution of the specific absorption rate of energy (SAR) in phantom models was analysed to detect clusters of mobile phones producing similar spatial deposition of energy in the head. The clusters' characteristics were described from the phones external features, frequency band and communication protocol. Compliance measurements with phones in cheek and tilt positions, and on the left and right side of a physical phantom were used. Phones used the Personal Digital Cellular (PDC), Code division multiple access One (CdmaOne), Global System for Mobile Communications (GSM) and Nordic Mobile Telephony (NMT) communication systems, in the 800, 900, 1500 and 1800 MHz bands. Each phone's measurements were summarised by the half-ellipsoid in which the SAR values were above half the maximum value. Cluster analysis used the Partitioning Around Medoids algorithm. The dissimilarity measure was based on the overlap of the ellipsoids, and the Manhattan distance was used for robustness analysis. Within the 800 MHz frequency band, and in part within the 900 MHz and the 1800 MHz frequency bands, weak clustering was obtained for the handset shape (bar phone, flip with top and flip with central antennas), but only in specific positions (tilt or cheek). On measurements of 120 phones, the three-dimensional distribution of SAR in phantom models did not appear to be related to particular external phone characteristics or measurement characteristics, which could be used for refining the assessment of exposure to radiofrequency energy within the brain in epidemiological studies such as the Interphone.

Evidence is lacking on whether health-benefiting community-based interventions differ in their effectiveness according to socioeconomic characteristics. We evaluated whether the benefit of a structured physical activity intervention on reducing mobility disability in older adults differs by education or income. The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicentre, randomised trial that compared a structured physical activity programme with a health education programme on the incidence of mobility disability among at-risk community-living older adults (aged 70-89 years; average follow-up of 2.6 years). Education (≤ high school (0-12 years), college (13-17 years) or postgraduate) and annual household income were self-reported (<$24 999, $25 000 to $49 999 and ≥$50 000). The risk of disability (objectively defined as loss of ability to walk 400 m) was compared between the 2 treatment groups using Cox regression, separately by socioeconomic group. Socioeconomic group×intervention interaction terms were tested. The effect of reducing the incidence of mobility disability was larger for those with postgraduate education (0.72, 0.51 to 1.03; N=411) compared with lower education (high school or less (0.93, 0.70 to 1.24; N=536). However, the education group×intervention interaction term was not statistically significant (p=0.54). Findings were in the same direction yet less pronounced when household income was used as the socioeconomic indicator. In the largest and longest running trial of physical activity amongst at-risk older adults, intervention effect sizes were largest among those with higher education or income, yet tests of statistical interactions were non-significant, likely due to inadequate power.

This paper describes the development of a mobile base for the Personal Mobility and Manipulation Appliance Generation II (PerMMA Gen II robotic wheelchair), an obstacle-climbing wheelchair able to move in structured and unstructured environments, and to climb over curbs as high as 8 inches. The mechanical, electrical, and software systems of the mobile base are presented in detail, and similar devices such as the iBOT mobility system, TopChair, and 6X6 Explorer are described. The mobile base of PerMMA Gen II has two operating modes: "advanced driving mode" on flat and uneven terrain, and "automatic climbing mode" during stair climbing. The different operating modes are triggered either by local and dynamic conditions or by external commands from users. A step-climbing sequence, up to 0.2 m, is under development and to be evaluated via simulation. The mathematical model of the mobile base is introduced. A feedback and a feed-forward controller have been developed to maintain the posture of the passenger when driving over uneven surfaces or slopes. The effectiveness of the controller has been evaluated by simulation using the open dynamics engine tool. Future work for PerMMA Gen II mobile base is implementation of the simulation and control on a real system and evaluation of the system via further experimental tests.

Replacing Ambulatory Surgical Follow-Up Visits With Mobile App Home Monitoring: Modeling Cost-Effective Scenarios

PubMed Central

Semple, John L; Coyte, Peter C

2014-01-01

Background Women’s College Hospital (WCH) offers specialized surgical procedures, including ambulatory breast reconstruction in post-mastectomy breast cancer patients. Most patients receiving ambulatory surgery have low rates of postoperative events necessitating clinic visits. Increasingly, mobile monitoring and follow-up care is used to overcome the distance patients must travel to receive specialized care at a reduced cost to society. WCH has completed a feasibility study using a mobile app (QoC Health Inc, Toronto) that suggests high patient satisfaction and adequate detection of postoperative complications. Objective The proposed cost-effectiveness study models the replacement of conventional, in-person postoperative follow-up care with mobile app follow-up care following ambulatory breast reconstruction in post-mastectomy breast cancer patients. Methods This is a societal perspective cost-effectiveness analysis, wherein all costs are assessed irrespective of the payer. The patient/caregiver, health care system, and externally borne costs are calculated within the first postoperative month based on cost information provided by WCH and QoC Health Inc. The effectiveness of telemedicine and conventional follow-up care is measured as successful surgical outcomes at 30-days postoperative, and is modeled based on previous clinical trials containing similar patient populations and surgical risks. Results This costing assumes that 1000 patients are enrolled in bring-your-own-device (BYOD) mobile app follow-up per year and that 1.64 in-person follow-ups are attended in the conventional arm within the first month postoperatively. The total cost difference between mobile app and in-person follow-up care is $245 CAD ($223 USD based on the current exchange rate), with in-person follow-up being more expensive ($381 CAD) than mobile app follow-up care ($136 CAD). This takes into account the total of health care system, patient, and external borne costs. If we examine health care system costs alone, in-person follow-up is $38 CAD ($35 USD) more expensive than mobile app follow-up care over the first postoperative month. The baseline difference in effect is modeled to be zero based on clinical trials examining the effectiveness of telephone follow-up care in similar patient populations. An incremental cost-effectiveness ratio (ICER) is not reportable in this scenario. An incremental net benefit (INB) is reportable, and reflects merely the cost difference between the two interventions for any willingness-to-pay value (INB=$245 CAD). The cost-effectiveness of mobile app follow-up even holds in scenarios where all mobile patients attend one in-person follow-up. Conclusions Mobile app follow-up care is suitably targeted to low-risk postoperative ambulatory patients. It can be cost-effective from a societal and health care system perspective. PMID:25245774

Although effective community falls prevention programmes for the older persons have been described, challenges remain in translating proven interventions into daily practice. To evaluate the efficacy, feasibility and acceptability of a falls prevention programme that can be integrated into daily activities in a group of community-dwelling older adults with risk of falling. A cohort study with intervention and comparison groups was designed to evaluate a 36-week group-based falls prevention exercise programme (FaME) in the community setting. Participants were aged 60 years or older, had fallen in the past 12 months, had fear of falling with avoidance of activities or had deficits in balance control. Primary outcome measures included assessment of balance control and mobility; secondary outcome measures included level of physical activity, assessment of fear of falling and health-related quality of life. There were 48 and 51 participants in the intervention and comparison groups, respectively. There were improvements in measurements of balance, walking speed and self-efficacy. The drop out rate was low (14.6% and 3.9% from the intervention and comparison groups, respectively). Overall compliance in the intervention group was 79%. Factors that motivated continued participation include the regular and long-term nature of the programme helping to reinforce their exercise habits, the simplicity of movements and friendliness of the group. The FaME programme improves balance, walking speed and reduces fear of falling. It could be widely promoted and integrated into regular health and social activities in community settings.

Can augmented physiotherapy input enhance recovery of mobility after stroke? A randomized controlled trial.

PubMed

2004-08-01

To discover if the provision of additional inpatient physiotherapy after stroke speeds the recovery of mobility. A multisite single-blind randomized controlled trial (RCT) comparing the effects of augmented physiotherapy input with normal input on the recovery of mobility after stroke. Three rehabilitation hospitals in North Glasgow, Scotland. Patients admitted to hospital with a clinical diagnosis of stroke, who were able to tolerate and benefit from mobility rehabilitation. We aimed to provide double the amount of physiotherapy to the augmented group. Primary outcomes were mobility milestones (ability to stand, step and walk), Rivermead Mobility Index (RMI) and walking speed. Seventy patients were recruited. The augmented therapy group received more direct contact with a physiotherapist (62 versus 35 minutes per weekday) and were more active (8.0% versus 4.8% time standing or walking) than normal therapy controls. The augmented group tended to achieve independent walking earlier (hazard ratio 1.48, 95% confidence interval 0.90-2.43; p=0.12) and had higher Rivermead Mobility Index scores at three months (mean difference 1.6; -0.1 to 3.3; p=0.068) but these differences did not reach statistical significance. There was no significant difference in any other outcome. A modest augmented physiotherapy programme resulted in patients having more direct physiotherapy time and being more active. The inability to show statistically significant changes in outcome measures could indicate either that this intervention is ineffective or that our study could not detect modest changes.

Since its introduction in 2009, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has been implemented in 617 laboratories in 47 countries. We completed a systematic review of the published literature on SLMTA. The review consists of two companion papers; this article examines quantitative evidence presented in the publications along with a meta-analysis of selected results. We identified 28 published articles with data from SLMTA implementation. The SLMTA programme was evaluated through audits based on a standard checklist, which is divided into 12 sections corresponding to the 12 Quality System Essentials (QSEs). Several basic service delivery indicators reported by programmes were also examined. Results for various components of the programme were reviewed and summarised; a meta-analysis of QSE results grouped by the three stages of the quality cycle was conducted for 126 laboratories in 12 countries. Global programme data show improved quality in SLMTA laboratories in every country, with average improvements on audit scores of 25 percentage points. Meta-analysis identified Improvement Management as the weakest stage, with internal audit (8%) and occurrence management (16%) showing the lowest scores. Studies documented 19% - 95% reductions in turn-around times, 69% - 93% reductions in specimen rejection rates, 76% - 81% increases in clinician satisfaction rates, 67% - 85% improvements in external quality assessment results, 50% - 66% decreases in nonconformities and 67% increases in staff punctuality. The wide array of results reported provides a comprehensive picture of the SLMTA programme overall, suggesting a substantive impact on provision of quality laboratory services and patient care. These comprehensive results establish a solid data-driven foundation for program improvement and further expansion.

The theory of planned behaviour attempts to explain factors which influence behaviour. One of these factors is intention. Positive or negative intentions are formed by a person's impression of the way other people would perceive similar behaviour (external forces). The authors of this study used the theory of planned behaviour to examine, compare and interpret the academic performance of students entering a university either via direct intake or via a bridging programme. This study focuses on the UniBridge programme offered by Universiti Brunei Darussalam (UBD), which is an intensive one-semester course that prepares students for undergraduate-level study. While direct-intake applicants pass minimum requirements for entry and are able to enrol directly into an undergraduate programme, applicants who do not meet these minimum requirements can join this bridging programme which is designed to be a "second-chance" entry option. Using a mixed-methods approach, the authors subjected student performance data of both direct-intake and bridge-programme undergraduates to statistical analyses, carried out interviews and then used the theoretical framework of planned behaviour to pinpoint individual attitudes and social pressures which form an intention to prepare for entry examinations. The results were mostly consistent and showed that the two groups were competitive in terms of undergraduate academic achievement, thus proving the second-chance programme to be effective in enabling students with poor A-Level results to experience academic confidence at university level. On the strength of these findings, the authors conclude their paper with recommendations for tertiary institutions to support lifelong learning initiatives through the use of multiple channels of entry.

Background Youth-friendly sexual and reproductive health services (YFHS) have high priority in many countries. Yet, little is known about the cost and cost-effectiveness of good quality YFHS in resource limited settings. This paper analyses retrospectively costs and potential cost-effectiveness of four well performing youth-friendly health centres (YFHC) in Moldova. This study assesses: (1) what were the costs of YFHSs at centre level, (2) how much would scaling-up to a national good quality YFHS programme cost, and (3) was the programme potentially cost-effective? Methods Four well performing YFHCs were selected for the study. YFHS costs were analysed per centre, funding source, service and person reached. The costing results were extrapolated to estimate cost of a good quality national YFHS programme in Moldova. A threshold analysis was carried out to estimate the required impact level for the YFHSs to break-even (become cost saving). Results Average annual cost of a well performing YFHC was USD 26,000 in 2011. 58% was financed by the National Health Insurance Company and the rest by external donors (42%). Personnel salaries were the largest expense category (47%). The annual implementation costs of a good quality YFHSs in all 38 YFHCs of Moldova were estimated to be USD 1.0 million. The results of the threshold analysis indicate that the annual break-even impact points in a YFHC for: 1) STI services would be >364 averted STIs, 2) early pregnancy and contraceptive services >178 averted unwanted pregnancies, and 3) HIV services only >0.65 averted new HIV infections. Conclusions The costing results highlight the following: 1) significant additional resources would be required for implementation of a good quality national YFHS programme, 2) the four well performing YFHCs rely heavily on external funding (42%), 3) which raises questions about financial sustainability of the programme. At the same time results of the threshold analysis are encouraging. The result suggest that, together the three SRH components (STI, early pregnancy and contraception, and HIV) are potentially cost saving. High cost savings resulting from averted lifetime treatment cost of HIV infected persons are likely to off-set the costs of STIs and unwanted pregnancies. PMID:25047074
