Isolated electrical microgrids employing renewable energy resources:analysis of the electrification of remote communities in Peru.

This project points out a brief overview of several concepts, as Renewable Energy Resources, Distributed Energy Resources, Distributed Generation, and describes the general architecture of an electrical microgrid, isolated or connected to the Medium Voltage Network. Moreover, the project focuses on a project carried out by GRECDH Department in collaboration with CITCEA Department, both belonging to Universitat Politécnica de Catalunya: it concerns isolated microgrids employing renewable energy resources in two communities in northern Peru. Several solutions found using optimization software regarding different generation systems (wind and photovoltaic) and different energy demand scenarios are commented and analyzed from an electrical point of view. Furthermore, there are some proposals to improve microgrid performances, in particular to increase voltage values for each load connected to the microgrid. The extra costs required by the proposed solutions are calculated and their effect on the total microgrid cost are taken into account; finally there are some considerations about the impact the project has on population and on people's daily life.

High prevalence of asthma in five remote indigenous communities in Australia

Data on the prevalence of asthma in children residing in remote indigenous communities in Australia are sparse, despite the many reports of high prevalence in nonindigenous children of this country. Two previous Australian studies have had poor participation rates, limiting interpretation of their results. A study of children in the Torres Strait and Northern Peninsula Area of Australia was conducted to document the prevalence of asthma symptoms. Five indigenous communities were randomly selected and trained interviewers, who were local indigenous health workers, recruited participants using a house-by-house approach. Information was collected by a structured face-to-face interview based on standardized questionnaire constructed from the protocol International Study of Asthma and Allergy in Childhood; 1,650 children were included in the study with a 98% response rate. Overall, the prevalence of self-reported ever wheezing was 21%,; 12% reported wheezing in the previous year; and 16%, reported ever having asthma, There was significant variation in the prevalence of asthma symptoms between communities. It is concluded that there are significant intercommunity variations in the prevalence of asthma symptoms in remote communities and that the prevalence in these communities is as high as in nonindigenous groups.

Soil-Transmitted Helminths, Poverty, and Malnutrition in Honduran Children Living in Remote Rural Communities

Soil-transmitted helminth (STH) infections are endemic in Honduras, but their prevalence according to the levels of poverty in the population has not been examined. The present cross-sectional study is aimed to determine the role of different levels of poverty in STH prevalence and infection intensity as well as the potential associations of STH infections with malnutrition and anemia. Research participants were children attending a medical brigade serving remote communities in Northern Honduras in June 2014. Demographic data were obtained, and poverty levels were determined using the unsatisfied basic needs method. STH infections were investigated by the Kato-Katz method; hemoglobin concentrations were determined with the HemoCue system; and stunting, thinness, and underweight were determined by anthropometry. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression models. Among 130 children who participated in this study, a high prevalence (69.2%) of parasitism was found and the poorest children were significantly more infected than those living in less poor communities (79.6% vs. 61.8%; P = 0.030). Prevalence rates of Trichuris trichiura, Ascaris lumbricoides, and hookworms were 69.2%, 12.3%, and 3.85%, respectively. In total, 69% of children had anemia and 30% were stunted. Households’ earthen floor and lack of latrines were associated with infection. Greater efforts should be made to reduce STH prevalence and improve overall childhood health, in particular, among the poorest children lacking the basic necessities of life.

Kidney and related chronic disease profiles and risk factors in three remote Australian Aboriginal communities

Morbidities and deaths from noncommunicable chronic diseases are greatly increased in remote Australian Aboriginal communities, but little is known of the underlying community-based health profiles. We describe chronic-disease profiles and their risk factors in 3 remote communities in the Northern Territory. Consenting adults (18+ years of age) in 3 communities participated in a brief history and examination between 2000 and mid-2003 as part of a systematic program to improve chronic-disease awareness and management. Participation was 67%,128%, and 62% in communities A, B, and C, respectively with a total of 1070 people examined. Current smokers included 41% of females and 72% of males. Most men were current drinkers, but most women were not. Parameters of body weight differed markedly by community, with mean body mass index (BMC) varying from 21.4 to 27.9 kg/m(2). Rates of chronic diseases were excessive but differed markedly; an almost threefold difference in the likelihood of any morbidity existed between communities A and C. Rates increased with age, but the greatest numbers of people with morbidities were in the middle-aged group. Most people had multiple morbidities with tremendous overlap. Hypertension and kidney disease appear to be early manifestations of the integrated chronic-disease syndrome, while diabetes is a late manifestation or complication. Substantial numbers of new cases of disease were identified by testing, and blood pressure improved in treated people with hypertension. Wide variations occur in body habitus, risk factors, and chronic-disease rates among communities, but an overwhelming need for effective smoking interventions exists in all. Systematic screening is useful in identifying high-risk individuals, most at early treatable stages there. Findings are very important for estimating current treatment needs, future burdens of disease, and for needs-based health services planning. Resources required will vary according to the burden of disease. (C) 2005 by the National Kidney Foundation, Inc.

Across the dividing range - bridging the divides: Pharmacy opportunities across the hospital/community and inter-professional divides in rural and remote Australia

Rural and remote areas of Australia offer many opportunities for innovation in healthcare services. Some true healthcare 'network' models based around rural pharmacy can be established and evaluated. The lines between community and hospital pharmacy are often blurred and communication between health professionals enhanced. The blurring divide between hospital and community pharmacy in rural and remote areas has provided significant advances in practice. Projects have been set up to investigate the feasibility of community pharmacists integrating care for patients. These projects take advantage of the dual roles and the enhanced interaction between pharmacists and other health professionals in the bush. Opportunities for provision of clinical services beyond the traditional supply role have been taken in a number of remote communities

Carotid intima-media thickness, cardiovascular risk factors and albuminuria in a remote Australian Aboriginal community

Background: Rates of cardiovascular disease and renal disease in Australian Aboriginal communities are high, as is the prevalence of some 'traditional' cardiovascular (CV) risk factors, such as diabetes and cigarette smoking. Recent work has highlighted the importance of markers of inflammation, such as C-reactive protein (CRP), homocysteine and albuminuria as predictors of cardiovascular risk in urban westernised settings. It is not clear how these factors relate to outcome in the setting of these remote communities, but very high CRP concentrations have been shown in this and other Aboriginal communities. Methods and results: In a cross-sectional survey including 237 adults in a remote Aboriginal community in the Northern Territory of Australia, we measured carotid intima-media thickness (IMT), together with blood pressure, diabetes, lipid levels, smoking and albuminuria, CRP and fibrinogen, serum homocysteine concentration, and IgG titres for Chlamydia pneumoniae, Helicobacter pylori and cytomegalovirus. Median carotid IMT was 0.63 [interquartile range 0.54-0.71] mm. As a categorical outcome, the prevalence of the highest IMT quartile ('increased IMT', greater than or equal to0.72 mm) was compared with the lower three quartiles. Increased IMT was associated in univariate analyses with greater waist circumference, systolic BP, fibrinogen and serum albumin concentrations, urine albumin/creatinine ratio and older age as continuous variables. Associations of increased IMT with some continuous variables were not linear; univariate associations were seen with the highest quartile (versus all other quartiles) of CRP and homocysteine concentration and CMV IgG titre. In a multivariate model age, smoking, waist circumference and the highest quartile of CRP concentrations (greater than or equal to14 mg/l) remained significant predictors of IMT greater than or equal to0.72 mm. Conclusions: Measurement of carotid IMT was possible in this remote setting. Increased IMT (greater than or equal to0.72 mm) was associated with increased CRP concentrations over a range that suggests infection/inflammation may be important determinants of cardiovascular risk in this setting. The associations of IMT with markers of renal disease seen in univariate analyses were explained in this analysis by confounding due to the associations of urine ACR with other risk factors.

Adapting the 'family wellbeing' empowerment program to the needs of remote indigenous school children

Objective: To adapt the Family Wellbeing empowerment program, which was initially designed to support adults to take greater control and responsibility for their decisions and lives, to the needs of Indigenous school children living in remote communities. Method. At the request of two schools in remote Indigenous communities in far north Queensland, a pilot personal development and empowerment program based on the adult Family Wellbeing principles was developed, conducted and evaluated in the schools. The main aims of the program were to build personal identity and to encourage students to recognise their future potential and be more aware of their place in the community and wider society. Results: Participation in the program resulted in significant social and emotional growth for the students. Outcomes described by participating students and teachers included increased analytical and reflective skills, greater ability to think for oneself and set goals, less teasing and bullying in the school environment, and an enhanced sense of identity, friendship and,social relatedness'. Conclusion: This pilot implementation of the Family Wellbeing Program adapted for schools demonstrated the program's potential to enhance Indigenous young people's personal growth and development. Challenges remain in increasing parental/ family involvement and ensuring the program's sustainability and transferability. The team has been working with relevant stakeholders to further develop and package the School-based Family Wellbeing program for Education Queensland's New Basics curriculum framework.

Proposed network of mobile libraries: alternative information to rural communities in Costa Rica

This study examines the services provided by the bookmobile of SINABI-Public Libraries in rural communities visited Costa Rica during 2009 and 2010 according to the sample selected for the presentation of a proposed Mobile Library Network to Costa Rica.Each country has very heterogeneous populations and the populations in unfavorable geographical areas (rural or urban fringe areas) and areas without library service or cultural institution, they have specific information needs. By its terms can not exercise the right to information, while urban areas have greater influence and social advantage to have easy access to various information resources.The mobile library services are presented as an ideal tool to deliver library services to any population, mainly those remote communities and vulnerable state as rural areas. Bookmobile is defined as any means of transport (buses, trains, boats, motorcycles, boats, animals, etc.), which shifts documentary material.

Project to investigate improving literacy and numeracy outcomes of distance education students in the early years of schooling

The project was commissioned to investigate and analyse the issue of effective support for distance education students in the early years of school to maximise literacy and numeracy outcomes. The scope of this project was limited to students living in rural and remote areas who are undertaking education at home and who are in their early years of schooling. For the purpose of this project, the early years are conceptualised as the first three years of formal compulsory schooling in each of the States and Territories. There were a number of key tasks for the project which included: 1. Examining of the role of home tutors/supervisors This included interviewing personnel from the State and Territory distance education providers as well as the principals, teachers, home tutors and children. 2. Describing literacy and numeracy teaching and learning, and the use of information and communication technologies (ICT) in distance education This aspect of the project involved a critical review and analysis of relevant literature and reports in the last five years, and a consideration of the new initiatives that had been implemented in the States and Territories in the last two years. 3. The development of resources Through examination of the role of home tutors/supervisors, and an examination of literacy and numeracy and the use of technology in distance education, three resources were developed: ● A guide for home tutors/supervisors and schools of distance education about effective intervention and assessment strategies to support students’ learning and to assist the home tutors/supervisors in implementing ICT to support the development of literacy and numeracy in the early years. ● A calendar of activities for literacy and numeracy that would act as a stimulus for integrated and authentic activity for young children. ● An embryonic website of resources for the stakeholders in rural and distance education that might act as a catalyst for future resource building and sharing. In this way the final key task of the project, which was to create a context for a strategic dissemination plan, was realised when a strategy to address effective dissemination of the findings of the project so as to maximise their usefulness for the relevant groups was achieved.

Taking telehealth to the bush: lessons from north Queensland

Networking North Queensland (NNQ) was a two-year project to improve access to health services in rural and remote communities. The project involved email and Internet access in 61 communities, in a region almost three times the size of the UK. Videoconferencing equipment was also installed at 21 sites and a total of 197 h of videoconferencing was recorded at 10 of the remote sites over 12 months. As a result of the project, health consumers enjoyed improved access to medical, specialist, allied health and primary health services. In addition, health service providers had better access to reliable, up-to-date health-care information via intranet and Internet services. Consideration of local issues-local needs and existing resources-was vital to the achievements of the project. Community involvement and community access were also important factors in its success.

Diagnostic reliability of an immunochromatographic test for Chagas disease screening at a primary health care centre in a rural endemic area

Many patients with Chagas disease live in remote communities that lack both equipment and trained personnel to perform a diagnosis by conventional serology (CS). Thus, reliable tests suitable for use under difficult conditions are required. In this study, we evaluated the ability of personnel with and without laboratory skills to perform immunochromatographic (IC) tests to detect Chagas disease at a primary health care centre (PHCC). We examined whole blood samples from 241 patients and serum samples from 238 patients. Then, we calculated the percentage of overall agreement (POA) between the two groups of operators for the sensitivity (S), specificity (Sp) and positive (PPV) and negative (NPV) predictive values of IC tests compared to CS tests. We also evaluated the level of agreement between ELISAs and indirect haemagglutination (IHA) tests. The readings of the IC test results showed 100% agreement (POA = 1). The IC test on whole blood showed the following values: S = 87.3%; Sp = 98.8%; PPV = 96.9% and NPV = 95.9%. Additionally, the IC test on serum displayed the following results: S = 95.7%; Sp = 100%; PPV = 100% and NPV = 98.2%. Using whole blood, the agreement with ELISA was 96.3% and the agreement with IHA was 94.1%. Using serum, the agreement with ELISA was 97.8% and the agreement with IHA was 96.6%. The IC test performance with serum samples was excellent and demonstrated its usefulness in a PHCC with minimal equipment. If the IC test S value and NPV with whole blood are improved, then this test could also be used in areas lacking laboratories or specialised personnel.

Community remoteness and birth outcomes among First Nations in Quebec

OBJECTIF: Chez les Autochtones, la relation entre le degré d'éloignement et les issues de naissance est inconnue. L’objectif de cette étude est d’évaluer cet impact parmi les Premières Nations du Québec. MÉTHODE : Nous avons utilisé les données vitales de Statistique Canada pour la province du Québec pour la période 1991-2000. L’ensemble des naissances géocodées parmi les communautés des Premières Nations groupées en quatre zones en se basant sur le degré d'éloignement a été analysé. Nous avons utilisé la régression logistique multi-niveaux pour obtenir des rapports de cotes ajustés pour les caractéristiques maternelles. RESULTATS : Le taux de naissances prématurées varie en fonction de l’éloignement de la zone d’habitation (8,2% dans la zone la moins éloignée et 5,2% dans la Zone la plus éloignée, P<0,01). En revanche, plus la zone est éloignée, plus le taux de mortalité infantile est élevé (6,9 pour 1000 pour la Zone 1 et 16,8 pour 1000 pour la Zone 4, P<0,01). Le taux élevé de mortalité infantile dans la zone la plus éloignée pourrait être partiellement expliqué par le fort taux de mortalité post-natale. Le taux de mort subite du nourrisson est 3 fois plus élevé dans la zone 4 par rapport à la zone 1. Cependant la mortalité prénatale ne présente pas de différences significatives en fonction de la zone malgré une fréquence élevée dans la zone 4. La morbidité périnatale était semblable en fonction de la zone après avoir ajusté pour l’âge, l’éducation, la parité et le statut civil. CONCLUSIONS : Malgré de plus faibles taux d’enfants à haut risque (accouchements prématurés), les Premières Nations vivant dans les communautés les plus éloignées ont un risque plus élevé de mortalité infantile et plus spécialement de mortalité post-néonatale par rapport aux Premières Nations vivant dans des communautés moins éloignées. Il y existe un grand besoin d’investissement en services de santé et en promotion de la santé dans les communautés les plus éloignées afin de réduire le taux de mortalité infantile et surtout post-néonatale.
