    Williams, Kim; Wassell, Stephen R

    2010-01-01

    Leon Battista Alberti was an outstanding polymath of the fifteenth century, alongside Piero della Francesca and before Leonardo da Vinci. While his contributions to architecture and the visual arts are well known and available in good English editions, and much of his literary and social writings are also available in English, his mathematical works are not well represented in readily available, accessible English editions have remained accessible only to specialists. The four treatises included here - Ludi matematici, De Componendis Cifris, Elementi di pittura and De lunularum quadratura - ar

  2. Josef Frank and the history of architecture: Gothic and the Renaissance, Leon Battista Alberti and Albrecht Dürer in the architectural discourse on Neues Bauen at the beginning of the 1930s

    Directory of Open Access Journals (Sweden)

    Caterina Cardemone

    2016-06-01

    Full Text Available The paper focuses on Josef Frank’s convinced use of historiographical arguments in his sharp critique of German modernist architecture. Frank’s attention to architectural history dates back to his education at the Technische Hochschule in Vienna, with Carl König, and the writing of a doctoral thesis on Leon Battista Alberti’s religious buildings in 1910. If a profound knowledge of Alberti’s writings informs Frank’s entire theoretical work, the point discussed here is the parallel between Neues Bauen and Gothic traced by Frank to exclude Neues Bauen from a true modernity, based, on the opposite, on a classical tradition of thought. An attempt is made to reconstruct Frank’s historiographical references and to insert his work in the broader historiographical context, thus highlighting a close link between architectural theory and critique on the one hand and contemporary historiographical constructions on the other.

  3. Brunelleschi's mirror, Alberti's window, and Galileo's 'perspective tube' O espelho de Brunelleschi, a janela de Alberti e o 'tubo' de Galileu

    Directory of Open Access Journals (Sweden)

    Samuel Y. Edgerton

    2006-10-01

    Full Text Available This essay argues that the advent of linear perspective, ca. 1425, when Filippo Brunelleschi painted a small panel of the Florentine Baptistery by applying the geometric rules of optical mirror reflection, was more than just an artistic event. Indeed, it subsequently had the most profound - and quite unanticipated - influence on the rise of modern science. Surely, by 1609, Galileo would not have understood what he saw when observing the moon through his newly invented optical telescope, then called the 'perspective tube,' had it not been for his training in perspective drawing. Yet, Brunelleschi's original dependence on the mirror two centuries earlier was intended not to reveal objective 'scientific' reality, but rather to reinforce Christian spiritual 'reality.' In 1435-6, Leon Battista Alberti, when codifying Brunelleschi's perspective in his famous "Treatise on Painting," substituted a gridded window for Brunelleschi's mirror, thus redirecting the purpose of perspective art away from revealing God's divine order as reflected on earth, to a more secular physical reality viewed directly in relation to human moral order.O presente ensaio defende que não foi somente um acontecimento artístico o advento da perspectiva linear (c. 1425, quando Filippo Brunelleschi ao pintar um pequeno painel no Batistério Florentino lançou mão das regras geométricas da reflexão em espelho ótico. Esse acontecimento veio a exercer uma profunda e inesperada influência no surgimento da ciência moderna. Com certeza, por volta de 1609, Galileu não teria compreendido o que via quando observava a lua através de seu recém-criado telescópio ótico, então chamado 'tubo de perspectiva', se não fosse sua familiaridade com o desenho em perspectiva. No entanto, a original dependência do espelho que Brunelleschi desenvolveu dois séculos antes não almejava revelar uma realidade 'científica' objetiva, mas sim reforçar a realidade espiritual cristã. Em 1435

    La creación plástica de Alberti puede ser entendida como un hecho global. Su producción expresa la unidad entre la poesía y la pintura, que estriba en un denominador común : la escritura. También encuentra en el ritmo, el dinamismo, los cromatismos, un equivalente de la musicalidad de la poesia. La literatura, la historia del arte, la grafología y la semiótica pueden evidenciar los paralelismos y las correspondencias entre los lenguajes de que se vale Alberti

    2012-07-01

    Giovanni Battista Morgagni is considered the Father of Pathology and contributed much to our early understanding of neuropathology. For example, he introduced the concept that diagnosis, prognosis, and treatment of disease must be based on an exact understanding of the pathologic changes in anatomic structures. Additionally, he contributed to what would become the discipline of neurosurgery and, for example, performed trepanation for head trauma. It is the contributions of such early pioneers as Morgagni that our current understanding of the neurosciences is based.

  12. Il Maestro della Commenda di Meldola e la magione ospitaliera di San Giovanni Battista

    Directory of Open Access Journals (Sweden)

    Paolo Cova

    2012-02-01

    Full Text Available L’intervento propone, attraverso l’indagine di alcuni dipinti di area forlivese, una prima ricostruzione della personalità di un interessante interprete locale del XV secolo, provvisoriamente denominato Maestro della Commenda di Meldola. Lo studio, parte integrante della mia tesi di dottorato, prende le mosse dall’analisi dell’affresco dell’Oratorio di San Giovanni Battista a Meldola, per poi allargarsi ad altre emergenze del territorio circostante, fino ai lacerti pittorici emersi nella chiesa della Santissima Trinità di Forlì. Nella prima parte dell’articolo viene ricostruita la storia dell’Oratorio di San Giovanni Battista presso Villa Fronticelli a Meldola: già magione templare di Santa Maria Biacque, nel 1312, in seguito al processo ai templari, passò alle dipendenze della precettoria dei cavalieri gerosolimitani di San Giovanni di Palareto. La realizzazione dell’affresco deve essere probabilmente inserita all’interno dei lavori di ristrutturazione intrapresi dai giovanniti dopo la metà del XV secolo. Nella seconda parte dell’articolo invece si procede alle indagini tecniche e stilistiche relative alla pittura murale che rappresenta la Madonna col Bambino e San Giovanni Battista. L’affresco mutilo è opera di un interessante maestro che agisce nella sfera del tardogotico locale, mostrando però tenui accenti rinascimentali caratteristici alla pittura forlivese tra sesto e settimo decennio del Quattrocento. Muovendo dalle ricerche di Anna Tambini e Giordani Viroli, attraverso l’analisi di diverse testimonianze del territorio, viene così proposta la ricostruzione di un corpus pittorico caratterizzato da stringenti affinità stilistiche, che, confermando l’appartenenza del suo anonimo pittore ad un milieu stilistico caro ad altri interpreti forlivesi del periodo, come il Maestro di Castrocaro o il Maestro di San Pier Damiani, aiuta ulteriormente a chiarire il panorama artistico romagnolo all’avvento della

    This presentation starts with Galileo's discovery of the microscope and the first Lyncei. Giovanni Heckius and Francesco Stelluti demonstrated different kinds of mosquitoes. Later, in Florence, the Academy of Cimento solved the problem of mosquito reproduction with the discoveries of Francesco Redi, Pietro Paolo da Sangallo, Giuseppe Del Papa and Giovanni Maria Lancisi in the 18th century. In 19th century Eugenio Ficalbi reviewed the Italian Culicids. Once Battista Grassi solved the cycle of Anopheles and Plasmodia, further researches followed by Golgi, Celli, Marchiafava, Bastianelli and Bignami, as well as by Roland Ross.

  14. Giovanni Battista Morgagni (1682-1771): father of pathologic anatomy and pioneer of modern medicine.

    Ghosh, Sanjib Kumar

    2017-06-01

    Giovanni Battista Morgagni (1682-1771) was an Italian anatomist who introduced the anatomo-clinical concept in medicine and established anatomy as the instrument to identify the seat and etiology of any disease. He was professor of anatomy at the prestigious University of Padua for more than 50 years. His first documented text in anatomy, Adversaria Anatomica was published in three volumes between 1706 and 1719. His accurate anatomical descriptions of human organs enhanced his reputation as the most famous anatomist of Europe during that period. Morgagni published the most important work of his life, the masterpiece in pathologic anatomy, De Sedibus, in 1761. The text is based on his pathologic observations from about 700 autopsy dissections of patients whom he had treated during their lifetime. De Sedibus provides the reader with a precise correlation between the anatomo-pathologic findings at post-mortem and the clinical symptoms of a disease observed during a lifetime. Morgagni's ability to integrate and synthesize information set him apart from his contemporaries, and his anatomo-clinical method was a major breakthrough in the history of medicine as it helped physicians to diagnose a disease, analyse the prognosis of that disease and prepare a management protocol for the same. His achievements led to the emergence of pathologic anatomy as an exact science and with him began modern medicine.

    Recent Italian laws emphasise Clinical Governance model as a priority for hospitals and Health Technology Assessment as one of the major tools in order to support local and hospital decisions as far as new health technologies are concerned. Our reported experience suggests managing solutions and appraises clinical issues in terms of effectiveness, efficiency and security of new and emerging technologies in order to plan and to create a system according to up to date Health Technology Assessment principles in San Giovanni Battista University Hospital-Turin. Mini-HTA reports have been realised on "Technology Intelligence" in prostate cancer treatment, percutaneous implantation of aortic valve prosthesis in high-risk patients with aortic valve disease and experimental Home Radiology project. In addition, 1167 health technologies have been evaluated through a database created ad hoc. 65% of the evaluations have been positive, less than 5% negative and the other 30% have been suspended waiting for deeper assessments. The future perspectives predict the realization of further Mini-HTA reports even through a revision of the managing model used.

    Directory of Open Access Journals (Sweden)

    Mário Henrique Simão D´Agostino

    2003-12-01

    Full Text Available Leon Battista Alberti's invectives, cast in the Sixth Book of his De re aedificatoria (1452 against the enrollment of precepts and the expositive order of De architectura libri decem, written by Vitruvius in the 1st century B. C., reverberate over a considerable number of works engaged in the exegesis of ancient text. Such judgement, however, clearly contrasts with the author's purpose in writing his Ten Books, repeatedly stated in the proems at each volume. The collation of the critics' recurring topics and of the historical vicissitudes of the treatise's elaboration brings important contributions to the still open question.

    Overcrowding in Emergency Departments (ED) is a common phenomenon worldwide, especially in metropolitan areas. The main reason for overcrowding is not inappropriate emergency department use by patients but rather a shortage of available hospital beds which results in extended ED stays for patients who need emergency admission. The aims of this study, conducted at the San Giovanni Battista (Molinette) University hospital in Turin (Italy), were a) to verify the existence of overcrowding in the hospital ED and b) to test whether, as stated in the literature, overcrowding is due to restricted access to hospital beds for patients needing emergency admission, and to identify contributing factors. Results show the existence of overcrowding and confirm the hypothesized cause.

    In 2012, Sierra Leone experienced its worst cholera outbreak in over 15 years affecting 12 of the country's 13 districts. With limited diagnostic capability, particularly in bacterial culture, the cholera outbreak was initially confirmed by microbiological testing of clinical specimens outside of Sierra Leone. During 2012 - 2013, in direct response to the lack of diagnostic microbiology facilities, and to assist in investigating and monitoring the cholera outbreak, diagnostic and reference services were established in Sierra Leone at the Central Public Health Reference Laboratory focusing specifically on isolating and identifying Vibrio cholerae and other enteric bacterial pathogens. Sierra Leone is now capable of confirming cholera cases by reference laboratory testing.

    Directory of Open Access Journals (Sweden)

    Semenova Yuliya Sergeevna

    2012-12-01

    Full Text Available The author considers the process of development of the architect's personality depicted in Vitruvy's uomo universale and as a scientist-theorist based on the work of L.B. Alberti where his role is the one of the founder of the imaginary world generated in the XVIIth century. The image of an architect is not static, it is transformable. Each time changes in the architectural mode of thinking, as well as in science, technology and arts, are reflected in his "faces". The paper represents a comparative analysis of antique, medieval, renaissance architectural consciousness of the XVIIth century. The idea of a universally educated personality (uomo universale, generated by Vitruvy, loses its importance in the Middle Ages. According to Alberti, the true goal of an architect was reduced to consideration of a plan and to its implementation in detailed drawings. That was already enough to speak about the project as a work of architectural art. In that case implementation of a project in reality became the business of workers rather than architects. Ideas of Alberti will find their reflection in the almost unknown novel and treatise that dates back to the end of the XVth century. It is entitled "Hypnerotomachia Poliphili'. Its authorship is attributed to Francesco Colonna, a Venetian monk. The model of «the paper architecture» which deals with ideas, rather than their material implementation will be more explicit here. (In spite of the fact, that the concept of the «paper architecture» is related to the name of G. B. Piranesi, architect of the XVIIIth century, the sources of this phenomenon are found in the Age of the Renaissance. Colonna actually cited Alberti, telling him to deal with the plan in his soul, "to always keep its completeness and wholeness", and not to fall to the level of simple builders and make building decorations. However the author of "Hypnerotomachia Poliphili", in his turn, overcomes the architectural tradition of Early

  13. Miguel de Cervantes’ La destruición de Numancia: Rafael Alberti and Federico García Lorca have two alternative theatrical projects

    Directory of Open Access Journals (Sweden)

    Sergio Arlandis

    2017-11-01

    Full Text Available The readings that some writers of the Generation of 27 made about our classics have had a wide range of interpretations. Miguel de Cervantes was one of those authors resumed at the dawn of the Spanish Civil War and one of his works, La destruición de Numancia, was soon considered as one of the ideological referents of the two sides. This work will focus on a specific discussion: to delve into the way in which two writers as Alberti and García Lorca, assimilated, so differently, the Cervantes’ legacy, one bringing to the maximum its politicization the classic tragedy with its staging theatrical in Madrid; and the other —and this has not been studied yet— by how he tried to move away from that political core, remaining with the whole theatrical structure as a foundation in La casa de Bernarda Alba, so that a possible Cervantine influence is proposed in García Lorca who, to date, had always been left out of those already pointed out by critics.

  17. Architecture and mathematics from antiquity to the future

    CERN Document Server

    2015-01-01

    The aim of this collection of essays is to present a broad portrait of the ways in which two seemingly different disciplines are interconnected. The diversity and varied texture of the essays richly illustrates the affinity between architecture and mathematics. As the almost 100 papers presented in this two-volume publication show, every age and every culture has relied on principles of mathematics incorporated in their works of architecture to imbue their built environment with meaning and order. Included are discussions of geometry, proportional systems, linear algebra, periodic and aperiodic tilings, fractals, perspective, computer science and mechanics. Western architecture of every period is examined: Egyptian, Roman, Medieval, Renaissance, Baroque, Enlightenment, twentieth-century and beyond, as is the architecture of Turkey, China, India, Japan, Australia and Islam. The mathematical nature of the architecture of Leon Battista Alberti, Andrea Palladio and Frank Lloyd Wright is examined, and the philosop...

    1999-01-01

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties.

    Between September 2014 and February 2015, the number of Ebola virus disease (EVD) cases reported in Sierra Leone declined in many districts. During this period, a major international response was put in place, with thousands of treatment beds introduced alongside other infection control measures. However, assessing the impact of the response is challenging, as several factors could have influenced the decline in infections, including behavior changes and other community interventions. We developed a mathematical model of EVD transmission, and measured how transmission changed over time in the 12 districts of Sierra Leone with sustained transmission between June 2014 and February 2015. We used the model to estimate how many cases were averted as a result of the introduction of additional treatment beds in each area. Examining epidemic dynamics at the district level, we estimated that 56,600 (95% credible interval: 48,300-84,500) Ebola cases (both reported and unreported) were averted in Sierra Leone up to February 2, 2015 as a direct result of additional treatment beds being introduced. We also found that if beds had been introduced 1 month earlier, a further 12,500 cases could have been averted. Our results suggest the unprecedented local and international response led to a substantial decline in EVD transmission during 2014-2015. In particular, the introduction of beds had a direct impact on reducing EVD cases in Sierra Leone, although the effect varied considerably between districts.

    Introduzione: da alcuni anni sta emergendo come
    l’organizzazione per processi sia un elemento decisivo
    per il governo e la gestione delle strutture
    aziendali. Tale orientamento sta assumendo sempre
    più credito anche in campo sanitario dove si registrano
    una serie di attività sperimentali tra le quali è
    un esempio il programma di ricerca proposto dal
    Cergas-Bocconi denominato “Il percorso assistenziale
    del paziente in ospedale”, che vede la partecipazione
    dell’ASO S. Giovanni Battista di Torino.

    Obiettivi: governare la complessità gestionale deipercorsi diagnostico-terapeutici e assicurarne la  qualità del dato. Costruire un sistema di indicatori utile a favorire il razionale confronto tra percorso di riferimento e percorso effettivo.

    Metodi: il primo passo è stato quello di elaborare un report informatico, mediante il nostro sistema informativo, che evidenziasse tutte le attività eseguite dal paziente in ospedale attraverso la raccolta “longitudinale” dei dati clinici. Per identificare eventuali scostamenti tra i percorsi di riferimento e i percorsi effettivi, sono stati costruiti degli indicatori di monitoraggio che, messi in rete, hanno permesso un’agevole valutazione degli iter diagnostico-
    terapeutici rispetto alla “tradizionale” consultazione delle cartelle cliniche.

    Risultati: é stato attivato un apposito modulo informatico
    che consente il controllo automatico dei percorsi di cura. Il medico viene facilitato nell’inserimento delle prestazioni erogabili e dei farmaci da somministrare utilizzando quanto definito nel percorso di riferimento. Viene lasciata la discrezionalità di potersi scostare dal protocollo, inserendo e/o eliminando specifiche prestazioni. L’output finale è
    costituito dalla possibilità di analizzare gli scostamenti

    From July 1, 1959 to August 15, 1961, Milton Rokeach studied three male patients at Ypsilanti State Hospital who believed that they were Jesus Christ. They met regularly together with Rokeach and his research staff, a procedure designed to challenge their delusional systems. He believed that Leon Gabor, the youngest of the three, would be the most likely to abandon his delusional beliefs. Instead, Leon met the challenges that the procedure posed by creative elaborations of his delusional system, especially through the adoption of a new name that gave the initial appearance of the abandonment of his Christ identity but in fact drew on aspects of the real Jesus Christ's identity that were missing from his earlier self-representation.

    Sierra Leone has one of the highest rates of female genital mutilation (FGM) in the world, and yet little is known about the health consequences of the practice. Purpose To explore whether and what kind of FGM-related health complications girls and women in Sierra Leone experience, and to elucidate their health care-seeking behaviors. Patients and methods A feasibility study was conducted to test and refine questionnaires and methods used for this study. Thereafter, a cross-section of girls and women (n = 258) attending antenatal care and Well Women Clinics in Bo Town, Bo District, in the southern region and in Makeni Town, Bombali District, in the northern region of Sierra Leone were randomly selected. Participants answered interview-administrated pretested structured questionnaires with open- ended-questions, administrated by trained female personnel. Results All respondents had undergone FGM, most between 10 and 14 years of age. Complications were reported by 218 respondents (84.5%), the most common ones being excessive bleeding, delay in or incomplete healing, and tenderness.

Out of those who reported complications, 187 (85.8%) sought treatment, with 89 of them visiting a traditional healer, 75 a Sowei (traditional circumciser), and 16 a health professional. Conclusion The high prevalence rate of FGM and the proportion of medical complications show that FGM is a matter for public health concern in Sierra Leone. Girls who undergo FGM before 10 years of age seem to be more vulnerable to serious complications than those who are older at the time of FGM. It is important that health care personnel are aware of, and look for possible complications from FGM, and encourage girls and women to seek medical care for their problems. PMID:22870046

    1991-01-01

    With soring population growth rates and minimal economic growth, the nations of Africa are afflicted with innumerable problems. Why then should Africa's developing countries worry about CO 2 emissions? First, because agricultural activities form the backbone of most African economies; thus, these nations may be particularly vulnerable to the negative impacts of climate change. Second, acting to reduce carbon emissions will bring about more efficient energy use. All of Africa could benefit from the improved use of energy. Finally, the accumulation of CO 2 in the atmosphere is a global problem with individual solutions; in order to reduce international emissions, all countries, including those in Africa, must contribute. Typical of many African countries, Ghana and Sierra Leone have among the lowest levels of energy demand per capita across the globe. primary energy demand per capita in these two West African nations equals about one quarter of the world's average and about one twentieth of the US average. This work summarizes the results of two long-term energy use and carbon emissions scenarios for Sierra Leone and Ghana. In the high emissions (HE) scenario for 2025, policy changes focused on galvanizing economic growth lead to significant increases in energy use and carbon emissions in Ghana and Sierra Leone between 1985 and 2025. In the low emissions (LE) scenario, the implementation of policies aimed specifically at curtailing CO 2 emissions significantly limits the increase in carbon in both nations by 2025

    The Leon Water Flood site has undergone one season of soil amendments and growth of specialized plants meant to colonize and accelerate the remediation of the salt-impacted site. The researchers characterized the impacted soil as to chemistry, added soil amendments, and planted several species of seedlings, and seeded the scarred areas. After the first growing season, the surface soil was again characterized and groundcover was also characterized. While plant growth was quite meager across the area, soil chemistry did improve over most of the two scars.

    To reconstruct the biography of the Polish otorhinolaryngologist Leon Zamenhof (1875-1934), a brother of Ludwik Zamenhof, who is famous for invention of the international language Esperanto. Biographical information was collected from pre-World War II resources. Zamenhof developed several important new forms of treatment to help the hearing impaired. Zamenhof was especially interested in the education of deaf children and the therapy necessary to facilitate their integration into society. His significant achievements were a phonetic method of therapy for the hearing impaired and an automatic device for ear insufflation that was considered indispensable in the management of pyorrhea. In addition, Zamenhof initiated various forms of social support among physicians within the medical community of Warsaw, Poland; made health care available to children with hearing impairments; and organized a Jewish school for deaf children. Zamenhof tried to change public attitudes toward deafness, working to promote the integration of the deaf into wider society. He also translated Polish literature into Esperanto. With similar aims to his brother Ludwik, Leon Zamenhof strived to enhance and broaden communication among people who could not hear and to persuade people to change their attitudes about deafness.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Leon, Zamora and Salamanca of the Comunidad Autonoma de Castilla-Leon.

Among 1,054 children, 309 (29%) were EVD positive and 697 (66%) EVD negative, with 48 (5%) missing. Contact history, conjunctivitis, and age were the strongest positive predictors for EVD. The PEP score had an area under receiver operating characteristics curve of 0.80. A PEP score of 7/10 was 92% specific and 44% sensitive; 3/10 was 30% specific, 94% sensitive. The PEP score could correctly classify 79%–90% of children and could be used to facilitate triage into risk categories, depending on the sensitivity or specificity required. PMID:29350145

    Little is known about potentially modifiable factors in Ebola virus disease in children. We undertook a retrospective cohort study of children <13 years old admitted to 11 Ebola holding units in the Western Area, Sierra Leone, during 2014–2015 to identify factors affecting outcome. Primary outcome was death or discharge after transfer to Ebola treatment centers. All 309 Ebola virus–positive children 2 days–12 years old were included; outcomes were available for 282 (91%). Case-fatality was 57%, and 55% of deaths occurred in Ebola holding units. Blood test results showed hypoglycemia and hepatic/renal dysfunction. Death occurred swiftly (median 3 days after admission) and was associated with younger age and diarrhea. Despite triangulation of information from multiple sources, data availability was limited, and we identified no modifiable factors substantially affecting death. In future Ebola virus disease epidemics, robust, rapid data collection is vital to determine effectiveness of interventions for children. PMID:27649367

  15. Ravenscar Computational Model compliant AADL Simulation on LEON2

    Full Text Available AADL has been proposed for designing and analyzing SW and HW architectures for real-time mission-critical embedded systems. Although the Behavioral Annex improves its simulation semantics, AADL is a language for analyzing architectures and not for simulating them. AADS-T is an AADL simulation tool that supports the performance analysis of the AADL specification throughout the refinement process from the initial system architecture until the complete, detailed application and execution platform are developed. In this way, AADS-T enables the verification of the initial timing constraints during the complete design process. In this paper we focus on the compatibility of AADS-T with the Ravenscar Computational Model (RCM as part of the TASTE toolset. Its flexibility enables AADS-T to support different processors. In this work we have focused on performing the simulation on a LEON2 processor.

    1999-01-01

    Terrestrial above-ground biomass production and utilisation in Sierra Leone was analysed for the years 1984/5 to 1990/1. The total production of biomass energy was estimated at an annual average of 131 PJ (39% from agriculture, 51% from forestry and 10% from livestock). Of the 117 PJ produced from agricultural and forestry operations, 37 PJ was harvested as firewood and burnt (10.9 GJ or 0.72 t wood per capita per year, supplying 80% of the country's energy), 12 PJ was harvested for food, 66 PJ was unutilised crop and forestry residues, 3 PJ was harvested crop residues for use directly as fuel, and 2 PJ was harvested and used for industrial purposes and not for fuel. Livestock produced wastes with an energy content of 13 PJ of which only 0.1 PJ was collected and used for fuel. Thus 54 PJ (41%) of the 131 PJ of biomass energy produced annually was actually utilised while 49 PJ remained as unused agricultural residues and dung, and a further 27 PJ was unused forestry residues. The total amount of biomass (fuelwood, residues and dung) used directly to provide energy, mostly in households, was estimated at 40 PJ (11.8 GJ per capita per year of 0.79 t fuelwood equivalent). Direct biomass energy utilisation in agroindustry (0.4 PJ) was negligible in comparison. Two assessments of Sierra Leone's biomass standing stock and MAI (mean annual increment) were examined in order to assess the sustainability of various biomass use scenarios. Large differences were found between the MAI of the two assessments, making it difficult to predict sustainability of biomass production and use. The estimation of total standing stock varied between 227 and 366 Mt and the estimation of MAI varied between 15 and 70 Mt. Analysis of the availability and use of the biomass resource is crucial if biomass energy is to be used on a sustainable basis. A software package has been developed and is available to draft biomass flow charts but further work is needed to incorporate social and economic

    Dynamic progress in the basic sciences such as clinical chemistry exerted a great influence on the development of clinical science in medicine in the 19th century. We should rate Prof. Leon Marchlewski among the group of prominent foreign and Polish scientists working in that period. Marchlewski was born in 1869 in Wloclawek, Poland. He began his chemical studies in Warsaw and then continued at the Zurich Technical University. After having graduated, he began working in the famous Edward Schunk's laboratory in Kersal near Manchester in England. At that time he achieved recognition for his research on the chemical affinity of dyes of the animal and plant world. Later he cooperated in this field with another great scholar Marceli Nencki. In 1900 he returned to Poland, and in 1906 he took charge of the Department of Medical Chemistry at Jagiellonian University. He was nominated for the Nobel Prize twice in 1913 and 1914 for his numerous achievements in the field of clinical chemistry. He took many positions at Jagiellonian University in Krakow, including dean and rector. In 1930-1935 he was a senator of the Republic of Poland. He died in 1946 in Krakow.

    The prevalence of Entamoeba histolytica, Giardia lamblia and other intestinal and urogenital parasites were assessed in five Inland Valley Swamp (IVS) development faming communities in the Moyamba District, South-central Sierra Leone. Stool and urine samples were submitted by 1106 individuals and examined by the iron-haematoxylin staining and the formalin-ether concentration techniques for faecal sample and centrifugation method for the urine samples. The overall parasitic infection rate was 61.7% while 5.9% of the population had multiple infections. E. histolytica infection rate was 12.3 % and most of the infected individuals were passing cysts. Giardia lamblia and Trichomonas vaginalis infection rates were 10.0% and 0.4% respectively. Among the helminth infections, Ascaris lumbricoides was the most commonly observed (13.7%), followed by hookworms (12.1 %), Trichuris trichiura (9.3%), Strongyloides stercoralis (7.7%) and tapeworms (2.6%). The high parasitic infection rate (61.7%) and the frequency of multiple infections indicate an interrelationship of environmental factors which support transmission rather than a single factor.

  4. A Self-Assessment of the Effectiveness to Control Radiation Sources in Sierra Leone

    There is an urgent need to effectively control sources of ionizing radiation. Sources of ionizing radiation pose serious occupational, public health, and environmental consequences, if not properly controlled. The government of Sierra Leone knows the importance of controlling these sources of ionizing radiation and of establishing an independent Nuclear Safety Infrastructure. Sierra Leone has no nuclear facilities but, it is rapidly developing its infrastructure in order to obtain nuclear technology. However, the regulatory effectiveness in controlling radiation risk is essential for the International Atomic Energy Agency to allow the transfer of nuclear technology. For this reason, this study will evaluate the status of the regulatory authority in Sierra Leone to control radiation risk. The International Atomic Energy Agency (IAEA) review mission to Sierra Leone found that the RPBA did not give sufficient enforcement powers to the Board Secretariat. The research evaluated the status of the regulatory authority of Sierra Leone. The status of the regulatory authority was evaluated against several parameters including management systems, regulatory processes, authorization, inspection, and enforcement. The ability to effectively control ionizing radiation sources depends on the status of the regulatory body. The Integrated Regulatory Review Service Report on Sierra Leone led us to infer that there is a need for the regulatory authority to rapidly improve its ability to control ionizing radiation sources in the country. The findings however, revealed that the overall strengths of the regulatory body in Sierra Leone slightly outnumber the weaknesses. Management systems have a ratio of 0.85:1 of strengths to weaknesses. This ratio makes management systems the weakest parameter evaluated. Thus there is need for stronger collaboration between management staff. The Regulatory processes have a ratio of 1.3:1, authorizations have a ratio of 4.3:1, inspections have ratio of 2

    The Ebola virus disease (EVD) epidemic that hit West Africa in 2013 was the worst outbreak of EVD in recorded history. While much has been published regarding the international and national-level EVD responses, there is a dearth of literature on district-level coordination and operational structures, successes, and failures. This article seeks to understand how the EVD response unfolded at the district level, namely the challenges to operationalizing EVD surveillance over the course of the outbreak in Port Loko and Kambia districts of Sierra Leone. We present here GOAL Global's understanding of the fundamental challenges to case investigation operations during the EVD response, including environmental and infrastructural, sociocultural, and political and organizational challenges, with insight complemented by a survey of 42 case investigators. Major challenges included deficiencies in transportation and communication resources, low morale and fatigue among case investigators, mismanagement of data, mistrust among communities, and leadership challenges. Without addressing these operational challenges, technical surveillance solutions are difficult to implement and hold limited relevance, due to the poor quality and quantity of data being collected. The low prioritization of operational needs came at a high cost. To mediate this, GOAL addressed these operational challenges by acquiring critical transportation and communication resources to facilitate case investigation, including vehicles, boats, fuel, drivers, phones, and closed user groups; addressing fatigue and low morale by hiring more case investigators, making timely payments, arranging for time off, and providing meals and personal protective equipment; improving data tracking efforts through standard operating procedures, training, and mentorship to build higher-quality case histories and make it easier to access information; strengthening trust in communities by ensuring familiarity and consistency of case

    The purpose of this document is to summarize the work done to evaluate the performance of the Leon3 soft-core processor in a radiation environment while instantiated in a radiation-hardened static random-access memory based field-programmable gate array. This evaluation will look at the differences between two soft-core processors: the open-source Leon3 core and the fault-tolerant Leon3 core. Radiation testing of these two cores was conducted at the Texas A&M University Cyclotron facility and Lawrence Berkeley National Laboratory. The results of these tests are included within the report along with designs intended to improve the mitigation of the open-source Leon3. The test setup used for evaluating both versions of the Leon3 is also included within this document.

    In August 2014, the National Institute for Communicable Diseases (NICD) in South Africa established a modular high-biosafety field Ebola diagnostic laboratory (SA FEDL) near Freetown, Sierra Leone in response to the rapidly increasing number of Ebola virus disease (EVD) cases. The SA FEDL operated in the Western Area of Sierra Leone, which remained a "hotspot" of the EVD epidemic for months. The FEDL was the only diagnostic capacity available to respond to the overwhelming demand for rapid EVD laboratory diagnosis for several weeks in the initial stages of the EVD crisis in the capital of Sierra Leone. Furthermore, the NICD set out to establish local capacity amongst Sierra Leonean nationals in all aspects of the FEDL functions from the outset. This led to the successful hand-over of the FEDL to the Sierra Leone Ministry of Health and Sanitation in March 2015. Between 25 August 2014 and 22 June 2016, the laboratory tested 11,250 specimens mostly from the Western Urban and Western Rural regions of Sierra Leone, of which 2,379 (21.14%) tested positive for Ebola virus RNA. The bio-safety standards and the portability of the SA FEDL, offered a cost-effective and practical alternative for the rapid deployment of a field-operated high biocontainment facility. The SA FEDL teams demonstrated that it is highly beneficial to train the national staff in the course of formidable disease outbreak and accomplished their full integration into all operational and diagnostic aspects of the laboratory. This initiative contributed to the international efforts in bringing the EVD outbreak under control in Sierra Leone, as well as capacitating local African scientists and technologists to respond to diagnostic needs that might be required in future outbreaks of highly contagious pathogens.

    Full Text Available The article draws on filmic, popular, and scholarly references in order to trace how Mike de Leon and his films have been regarded, since his landmark entrance into Philippine cinema as director, up to the present. Specifically, it locates De Leon within the subtly shifting discourse of nationalist film scholarship and historicizing, and discusses how he and his films are written about, identified, associated or networked with other filmmakers and films, or utilized in discourses about the Philippines, Philippine cinema, or Philippine culture.The article locates De Leon as (1 an insider of Philippine cinema history, (2 an outsider of the commercial film industry, and (3 a hero of the mythic Golden Age of the National Cinema. It also maps out his filmography within the nationalist agenda; appraises what filmmakers, commentators, and scholars have articulated about his films; and analyzes the thematic and stylistic trajectories of his later works. Finally, it discusses how De Leon is being written into today’s discourse of Philippine cinema.

  4. Scaling up family planning in Sierra Leone: A prospective cost-benefit analysis.

    2017-12-01

    Family planning is commonly regarded as a highly cost-effective health intervention with wider social and economic benefits. Yet use of family planning services in Sierra Leone is currently low and 25.0% of married women have an unmet need for contraception. This study aims to estimate the costs and benefits of scaling up family planning in Sierra Leone. Using the OneHealth Tool, two scenarios of scaling up family planning coverage to currently married women in Sierra Leone over 2013-2035 were assessed and compared to a 'no-change' counterfactual. Our costing included direct costs of drugs, supplies and personnel time, programme costs and a share of health facility overhead costs. To monetise the benefits, we projected the cost savings of the government providing five essential social services - primary education, child immunisation, malaria prevention, maternal health services and improved drinking water - in the scale-up scenarios compared to the counterfactual. The total population, estimated at 6.1 million in 2013, is projected to reach 8.3 million by 2035 in the high scenario compared to a counterfactual of 9.6 million. We estimate that by 2035, there will be 1400 fewer maternal deaths and 700 fewer infant deaths in the high scenario compared to the counterfactual. Our modelling suggests that total costs of the family planning programme in Sierra Leone will increase from US$4.2 million in 2013 to US$10.6 million a year by 2035 in the high scenario. For every dollar spent on family planning, Sierra Leone is estimated to save US$2.10 in expenditure on the five selected social sector services over the period. There is a strong investment case for scaling up family planning services in Sierra Leone. The ambitious scale-up scenarios have historical precedent in other sub-Saharan African countries, but the extent to which they will be achieved depends on a commitment from both the government and donors to strengthening Sierra Leone's health system post-Ebola.

    2017-12-21

    This study provides the first assessment of decadal changes in mangrove extents in Sierra Leone. While significant advances have been made in mangrove mapping using remote sensing, no study has documented long-term changes in mangrove extents in Sierra Leone-one of the most vulnerable countries in West Africa. Such understanding is critical for devising regional management strategies that can support local livelihoods. We utilize multi-date Landsat data and cloud computational techniques to quantify spatiotemporal changes in land cover, with focus on mangrove ecosystems, for 1990-2016 along the coast of Sierra Leone. We specifically focus on four estuaries-Scarcies, Sierra Leone, Yawri Bay, and Sherbro. We relied on the k-means approach for an unsupervised classification, and validated the classified map from 2016 using ground truth data collected from Sentinel-2 and high-resolution images and during field research (accuracy: 95%). Our findings indicate that the Scarcies river estuary witnessed the greatest mangrove loss since 1990 (45%), while the Sierra Leone river estuary experienced mangrove gain over the last 26 years (22%). Overall, the Sierra Leone coast lost 25% of its mangroves between 1990 and 2016, with the lowest coverage in 2000, during the period of civil war (1991-2002). However, natural mangrove dynamics, as supported by field observations, indicate the potential for regeneration and sustainability under carefully constructed management strategies.

    Full Text Available Chemical control trials against Phytophthora capsici (Leon on pepper cultivations in Morocco. Pepper protection trials against collar and root rot have been undertaken under laboratory and culture conditions using Aliette (80 % of phosethylaluminium and Ridomil M 58 (10 % of metalaxyl associated to 48 % of maneb. It has been proved that, contrary to Ridomil M 58, Aliette does not protect the hostplant when the Phytophthora capsici (Leon zoospores are used as inoculum. But both fongicides are active when inoculating with a mycelian suspension. Trials undertaken under plastic glasshouses confirmed the laboratory results both with an artificial inoculation and with a natural one on contaminated soil. Only Ridomil M 58 provides satisfactory protection during the first weeks after the treatment. When disease propagation conditions are particularly favorable (permanent presence of an active inoculum source, the protection given by repeated Ridomil M 58 applications gradually disappears after a few weeks.

  11. The gospel in context: Hiebert’s critical contextualisation and charismatic movements in Sierra Leone

    2016-09-01

    Full Text Available This article examines the process of contextualisation adopted by charismatic movements (CMs in Sierra Leone. In it I use Hiebert’s model of critical contextualisation to evaluate the biblical depth and cultural sensitivity of the CMs’ contextualisation. Three ongoing cultural issues are especially highlighted as crucial and are used as the point of departure in the discussions: initiation ceremonies, polygamous marriage practices and ancestral rituals. The article concludes that, whilst the danger of syncretism is likely to occur where uncritical forms of contextualisation are employed, the CMs in Sierra Leone are attempting to address themes that are concurrent with the African sensibilities of its followers. This is an effort to build authentic forms of Christianity that are faithful to Holy Scripture and relevant to the setting in which they are developed.

    This is the first study to compare health status and access to health care services between disabled and non-disabled men and women in urban and peri-urban areas of Sierra Leone. It pays particular attention to access to reproductive health care services and maternal health care for disabled women. A cross-sectional study was conducted in 2009 in 5 districts of Sierra Leone, randomly selecting 17 clusters for a total sample of 425 households. All adults who were identified as being disabled, as well as a control group of randomly selected non-disabled adults, were interviewed about health and reproductive health. As expected, we showed that people with severe disabilities had less access to public health care services than non-disabled people after adjustment for other socioeconomic characteristics (bivariate modelling). However, there were no significant differences in reporting use of contraception between disabled and non-disabled people; contrary to expectations, women with disabilities were as likely to report access to maternal health care services as did non-disabled women. Rather than disability, it is socioeconomic inequality that governs access to such services. We also found that disabled women were as likely as non-disabled women to report having children and to desiring another child: they are not only sexually active, but also need access to reproductive health services. We conclude that disparity in access to government-supported health care facilities constitutes a major and persisting health inequity between persons with and without disabilities in Sierra Leone. Ensuring equal access will require further strengthening of the country's health care system. Furthermore, because the morbidity and mortality rates of pregnant women are persistently high in Sierra Leone, assessing the quality of services received is an important priority for future research.

  15. Distance, accessibility and costs. Decision-making during childbirth in rural Sierra Leone: A qualitative study.

    Laura Treacy

    Full Text Available Sierra Leone has one of the highest maternal mortality ratios in the world. Efforts to reduce maternal mortality have included initiatives to encourage more women to deliver at health facilities. Despite the introduction of the free health care initiative for pregnant women, many women still continue to deliver at home, with few having access to a skilled birth attendant. In addition, inequalities between rural and urban areas in accessing and utilising health facilities persist. Further insight into how and why women make decisions around childbirth will help guide future plans and initiatives in improving maternal health in Sierra Leone. The objective of this study was to explore the perceptions and decision-making processes of women and their communities during childbirth in rural Sierra Leone.Data were collected through seven focus group discussions and 22 in-depth interviews with recently pregnant women and their community members in two rural villages. Data were analysed using systematic text condensation. Findings revealed that decision-making processes during childbirth are dynamic, intricate and need to be understood within the broader social context that they take place. Factors such as distance and lack of transport, perceived negative behaviour of hospital staff, direct and indirect financial obstacles, as well as the position of women in society all interact and influence how and what decisions are made.Pregnant women face multiple interacting vulnerabilities that influence their healthcare-seeking decisions during pregnancy and childbirth. Future initiatives to improve access and utilisation of safe healthcare services for pregnant women need to be based on adequate knowledge of structural constraints and health inequities that affect women in rural Sierra Leone.

    Leon Kass is much misunderstood. He is not simply a Republican ideologue who tailored his ideas to break out of the ivory tower and into the halls of power. Nor does he look simply to use human nature as a moral guide. When the full range of his writings is considered and set in the tradition of his teachers, Hans Jonas and Leo Strauss, what emerges is a natural law position colored by religious revelation.

    2012-01-01

    In Sierra Leone, West Africa, there are many people with disabilities in need of rehabilitation services after a long civil war. The aim of this qualitative study was to explore the experiences of prosthetic and orthotic service delivery in Sierra Leone from the local staff's perspective. Fifteen prosthetic and orthotic technicians working at all the rehabilitation centres providing prosthetic and orthotic services in Sierra Leone were interviewed. The interviews were transcribed and subjected to latent content analysis. One main theme emerged: sense of inability to deliver high-quality prosthetic and orthotic services. This main theme was generated from eight sub-themes: Desire for professional development; appraisals of work satisfaction and norms; patients neglected by family; limited access to the prosthetic and orthotic services available; problems with materials and machines; low public awareness concerning disabilities; marginalisation in society and low priority on the part of government. The findings illustrated traditional beliefs about the causes of disability and that the public's attitude needs to change to include and value people with disabilities. Support from international organisations was considered necessary as well as educating more prosthetic and orthotic staff to a higher level.

    Reported levels of mental health and psychosocial problems rose during the 2014-2015 Ebola virus disease outbreak in Sierra Leone. As part of the emergency response, existing plans to create mental health units within the existing hospital framework were brought forward. A nurse-led mental health and psychosocial support service, with an inpatient liaison service and an outpatient clinic, was set up at the largest government hospital in the country. One mental health nurse trained general nurses in psychological first aid, case identification and referral pathways. Health-care staff attended mental well-being workshops on coping with stigma and stress. Mental health service provision in Sierra Leone is poor, with one specialist psychiatric hospital to serve the population of 7 million. From March 2015 to February 2016, 143 patients were seen at the clinic; 20 had survived or had relatives affected by Ebola virus disease. Half the patients (71) had mild distress or depression, anxiety disorders and grief or social problems, while 30 patients presented with psychosis requiring medication. Fourteen non-specialist nurses received mental health awareness training. Over 100 physicians, nurses and auxiliary staff participated in well-being workshops. A nurse-led approach within a non-specialist setting was a successful model for delivering mental health and psychosocial support services during the Ebola outbreak in Sierra Leone. Strong leadership and partnerships were essential for establishing a successful service. Lack of affordable psychotropic medications, limited human resources and weak social welfare structures remain challenges.

    This study provides the first assessment of decadal changes in mangrove extents in Sierra Leone. While significant advances have been made in mangrove mapping using remote sensing, no study has documented long-term changes in mangrove extents in Sierra Leone—one of the most vulnerable countries in West Africa. Such understanding is critical for devising regional management strategies that can support local livelihoods. We utilize multi-date Landsat data and cloud computational techniques to quantify spatiotemporal changes in land cover, with focus on mangrove ecosystems, for 1990–2016 along the coast of Sierra Leone. We specifically focus on four estuaries—Scarcies, Sierra Leone, Yawri Bay, and Sherbro. We relied on the k-means approach for an unsupervised classification, and validated the classified map from 2016 using ground truth data collected from Sentinel-2 and high-resolution images and during field research (accuracy: 95%). Our findings indicate that the Scarcies river estuary witnessed the greatest mangrove loss since 1990 (45%), while the Sierra Leone river estuary experienced mangrove gain over the last 26 years (22%). Overall, the Sierra Leone coast lost 25% of its mangroves between 1990 and 2016, with the lowest coverage in 2000, during the period of civil war (1991–2002). However, natural mangrove dynamics, as supported by field observations, indicate the potential for regeneration and sustainability under carefully constructed management strategies. PMID:29267247

    2015-07-01

    This paper aims to study the physical and socioeconomic transformations of rural settlements belonging to the Spanish region of Castile and Leon, throughout the second half of the 20th century. The evolution of urban form is analyzed, using a geographical information system (GIS) and calculating several shape metrics, and is then related to historical demographical data. The results are meant to show the effects of functional specialization, caused by the integration of rural regions in global economic hierarchies, on settlement structures and patterns. Gradual loss of the traditional features of Castilian villages, such as urban compactness and integration in the landscape, due to the disappearance or neglect of vernacular architecture and the construction of new industrial infrastructures, poses a risk for future place-based development policies. It is deemed necessary to preserve local identity and avoid destruction or degradation of the traditional heritage for revitalizing these territories. (Author)

  3. The Impact of the West Africa Ebola Outbreak on Obstetric Health Care in Sierra Leone.

    Directory of Open Access Journals (Sweden)

    Kim J Brolin Ribacke

    Full Text Available As Sierra Leone celebrates the end of the Ebola Virus Disease (EVD outbreak, we can begin to fully grasp its impact on already weak health systems. The EVD outbreak in West Africa forced many hospitals to close down or reduce their activity, either to prevent nosocomial transmission or because of staff shortages. The aim of this study is to assess the potential impact of EVD on nationwide access to obstetric care in Sierra Leone.Community health officers collected weekly data between January 2014-May 2015 on in-hospital deliveries and caesarean sections (C-sections from all open facilities (public, private for-profit and private non-profit sectors offering emergency obstetrics in Sierra Leone. This was compared to official data of EVD cases per district. Logistic and Poisson regression analyses were used to compute risk and rate estimates. Nationwide, the number of in-hospital deliveries and C-sections decreased by over 20% during the EVD outbreak. The decline occurred early on in the EVD outbreak and was mainly attributable to the closing of private not-for-profit hospitals rather than government facilities. Due to difficulties in collecting data in the midst of an epidemic, limitations of this study include some missing data points.Both the number of in-hospital deliveries and C-sections substantially declined shortly after the onset of the EVD outbreak. Since access to emergency obstetric care, like C-sections, is associated with decreased maternal mortality, many women are likely to have died due to the reduced access to appropriate care during childbirth. Future research on indirect health effects of health system breakdown should ideally be nationwide and continue also into the recovery phase. It is also important to understand the mechanisms behind the deterioration so that important health services can be reestablished.

    Spatial and temporal distribution of the radioisotopes concentrations were determined in sediments near the surface and core samples extracted from two reservoirs located in an arid region close to Chihuahua City, Mexico. At San Marcos reservoir one core was studied, while from Luis L. Leon reservoir one core from the entrance and another one close to the wall were investigated. 232 Th-series, 238 U-series, 40 K and 137 Cs activity concentrations (AC, Bq kg −1 ) were determined by gamma spectrometry with a high purity Ge detector. 238 U and 234 U ACs were obtained by liquid scintillation and alpha spectrometry with a surface barrier detector. Dating of core sediments was performed applying CRS method to 210 Pb activities. Results were verified by 137 Cs AC. Resulting activity concentrations were compared among corresponding surface and core sediments. High 238 U-series AC values were found in sediments from San Marcos reservoir, because this site is located close to the Victorino uranium deposit. Low AC values found in Luis L. Leon reservoir suggest that the uranium present in the source of the Sacramento – Chuviscar Rivers is not transported up to the Conchos River. Activity ratios (AR) 234 U/ 238 U and 238 U/ 226 Ra in sediments have values between 0.9–1.2, showing a behavior close to radioactive equilibrium in the entire basin. 232 Th/ 238 U, 228 Ra/ 226 Ra ARs are witnesses of the different geological origin of sediments from San Marcos and Luis L.

    Limited clinical and laboratory data are available on patients with Ebola virus disease (EVD). The Kenema Government Hospital in Sierra Leone, which had an existing infrastructure for research regarding viral hemorrhagic fever, has received and cared for patients with EVD since the beginning of the outbreak in Sierra Leone in May 2014. We reviewed available epidemiologic, clinical, and laboratory records of patients in whom EVD was diagnosed between May 25 and June 18, 2014. We used quantitative reverse-transcriptase-polymerase-chain-reaction assays to assess the load of Ebola virus (EBOV, Zaire species) in a subgroup of patients. Of 106 patients in whom EVD was diagnosed, 87 had a known outcome, and 44 had detailed clinical information available. The incubation period was estimated to be 6 to 12 days, and the case fatality rate was 74%. Common findings at presentation included fever (in 89% of the patients), headache (in 80%), weakness (in 66%), dizziness (in 60%), diarrhea (in 51%), abdominal pain (in 40%), and vomiting (in 34%). Clinical and laboratory factors at presentation that were associated with a fatal outcome included fever, weakness, dizziness, diarrhea, and elevated levels of blood urea nitrogen, aspartate aminotransferase, and creatinine. Exploratory analyses indicated that patients under the age of 21 years had a lower case fatality rate than those over the age of 45 years (57% vs. 94%, P=0.03), and patients presenting with fewer than 100,000 EBOV copies per milliliter had a lower case fatality rate than those with 10 million EBOV copies per milliliter or more (33% vs. 94%, P=0.003). Bleeding occurred in only 1 patient. The incubation period and case fatality rate among patients with EVD in Sierra Leone are similar to those observed elsewhere in the 2014 outbreak and in previous outbreaks. Although bleeding was an infrequent finding, diarrhea and other gastrointestinal manifestations were common. (Funded by the National Institutes of Health and

    Sierra Leone has faced a shortage and maldistribution of staff in its post-conflict period. This long-standing challenge is now exacerbated by the systemic shock and damage wrought by Ebola. This study aimed to investigate the importance of different motivation factors in rural areas in Sierra Leone and thus to contribute to better decisions on financial and non-financial incentive packages, here and in similar contexts. This article is based on participatory life histories, conducted in 2013 with 23 health workers (doctors, nurses, midwives and Community Health Officers) in four regions of Sierra Leone who had worked in the sector since 2000. Although the interviews covered a wide range of themes, here we present findings on motivating and demotivating factors for staff, especially those in rural areas, based on thematic analysis of transcripts. Rural health workers face particular challenges, some of which stem from the difficult terrain, which add to common disadvantages of rural living (poor social amenities, etc.). Poor working conditions, emotional and financial costs of separation from families, limited access to training, longer working hours (due to staff shortages) and the inability to earn from other sources make working in rural areas less attractive. Moreover, rules on rotation which should protect staff from being left too long in rural areas are not reported to be respected. By contrast, poor management had more resonance in urban areas, with reports of poor delegation, favouritism and a lack of autonomy for staff. Tensions within the team over unclear roles and absenteeism are also significant demotivating factors in general. This study provides important policy-focused insights into motivation of health workers and can contribute towards building a resilient and responsive health system, incorporating the priorities and needs of health workers. Their voices and experiences should be taken into account as the post-Ebola landscape is shaped.

    The aim of this study was to describe experiences of attitudes in the society of Sierra Leone from the perspective of individuals with poliomyelitis and people with amputations using orthotic or prosthetic devices. Individual interviews were conducted using open-ended questions. Twelve participants with amputations or polio were included. Content analysis was applied to the data. The following six themes emerged during data analysis: Experience of negative attitudes; Neglected and respected by family; Traditional beliefs; The importance of assistive devices; People with disability struggle with poverty; and The need for governmental and international support. In Sierra Leone, people with disabilities face severe discrimination. They need to be included, recognized, and supported to a greater extent by the society, the community, and the family, as well as by the government and international organizations. Traditional beliefs have a negative impact on people with physical disabilities and are an important cause of discrimination in Sierra Leone. Prosthetic and orthotic devices are vital for people with physical disability and offer increased dignity. Prosthetic and orthotic services need to be accessible and affordable. Poverty affects access to education, employment, and health care for Sierra Leoneans with physical disabilities, forcing them to resort to begging to cover basic living needs. Implications for Rehabilitation In Sierra Leone, traditional beliefs related to disability and public attitudes need to change in order to protect the human rights of people with disabilities. Increased public awareness of disability and implementation of the United Nations Convention on the Rights of Persons with Disabilities (CRPD) at different levels in society is needed. To increase access to prosthetic and orthotic services in Sierra Leone, these services need to be affordable and related costs, such as transport, need to be covered by support. Increased access to

Thus, a series of jurists and economists had understand the necessity and opportunity of knowledge in the domain of financial science, of the financial law, taking into consideration the fact that the difficulties which they have met at those times obliged them to take the responsibility to make every simple citizen and every person with political or administrative responsibility by the state understand the problems of public administration. In approaching the given subject I have chosen to use some of the methods of scientific research, respectively: the historical method (financial science being presented succinct through the process of its evolution along the years, interpretation methods and a combination of quality and quantity approach, namely the method of analyzing archive documents and the studies of professor Gheorghe N.

    The mineral sector plays a key role in the economies of Guinea, Liberia, and Sierra Leone. The onset of the Ebola virus disease (EVD) outbreak in early 2014, together with changes in mineral market conditions, raised questions regarding the status of mining operations and of mineral development and exploration projects in all three countries. Mineral projects were the underpinnings of World Bank short-term forecasts of increases in gross domestic product (GDP) for all three countries and were expected to be the basis of future economic growth. The significant delay or cancellation of these projects could result in a major economic setback for all three countries.

    Full Text Available The present historiographie research on the Pious Schools in Castille and Leon during the Bourbon Restoration has studied the public, institutional and social dimensions of these centres. The liberal revolutions of the nineteenth century defended the escolapios and even let them expand to such an extent that the end of the century they increased considerably. If it happened so it was because its educative work brought great benefits to the State as well as the citizens. Therefore, there was a symbiosis between the unimaginable in other teaching institutions.

    Hoddeson, Lilian; Kolb, Adrienne

    We examine the roles of vision and leadership in creating and directing Fermi National Accelerator Laboratory from the late 1960s through the 1980s. The story divides into two administrations having different problems and accomplishments, that of Robert R. Wilson from 1967-1978, which saw the transformation from cornfield to frontier physics facility, and that of Leon M. Lederman from 1979-1989, in which the laboratory evolved into one of the world's major high-energy facilities. Lederman's pragmatic vision of a user-based experimental community helped him to convert the pioneering facility that Wilson had built frugally into a laboratory with a stable scientific, cultural, and funding environment.

    Many low-income and crises-affected countries like Sierra Leone struggle with the recruitment and retention of their health professionals, particularly nurses and doctors. There are multiple factors that influence the 'recruitment to retention' pipeline. The first stage of an exploration into the issues influencing the availability of qualified health care workers may focus on the aspects which influence their entry into relevant educational programmes. This paper explores the reasons given by junior doctors in Sierra Leone for wanting to become a doctor. It also describes entry procedures into undergraduate medical education. In-depth interviews were conducted with purposively sampled junior doctors ( n  = 15) from the only medical school in Sierra Leone in October 2013. Digital diaries and two follow-up interviews were used to explore their evolving career experiences and aspirations until November 2016. In addition, semi-structured interviews with key informants ( n  = 20), including senior teaching staff at the medical school ( n  = 7), were conducted. Thematic analysis was used to explore linkages and themes across cases. Six themes were identified. The most commonly mentioned reasons for wanting to become a doctor were a desire to help (theme 4) and the influence of family and friends, via role modelling (theme 2) and verbal encouragement (theme 3). Other motives were an interest from a young age (theme 1), being attracted by the job prospects (theme 5), and having an intellectual and science capacity (theme 6). Junior doctors gave at least two and up to six reasons for applying to enter the medical profession. Doctors were allowed entry to the medical school largely based on their previous academic performance. This study showed that multiple reasons underlie the decision to apply for entrance to medical school and the decision to enter medicine is complex. These findings may inform the review of future admission procedures by the medical school

    Full Text Available The main focus of this paper is to examine the impact of the real effective exchange rate on economic growth in Sierra Leone. First an analytical framework is developed to identify the determinants of the real effective exchange rate. Using quarterly data and employing recent econometric techniques, the relationship between the real effective exchange rate and economic growth is then investigated. A bivariate Granger causality test was also employed as part of the methodology to examine the causal relationship between the real exchange rate and economic growth. The empirical results suggest that the real effective exchange rate correlates positively with economic growth, with a statistically significant coefficient. The results also indicate that monetary policy is relatively more effective than fiscal policy in the long run, and evidence of the real effective exchange rate causing economic growth was profound. In addition, the results showed that terms of trade, exchange rate devaluation, investment to GDP ratio and an excessive supply of domestic credit were the main determinants of the real exchange rate in Sierra Leone.

    The 2013-2015 Ebola virus disease (EVD) epidemic is caused by the Makona variant of Ebola virus (EBOV). Early in the epidemic, genome sequencing provided insights into virus evolution and transmission and offered important information for outbreak response. Here, we analyze sequences from 232 patients sampled over 7 months in Sierra Leone, along with 86 previously released genomes from earlier in the epidemic. We confirm sustained human-to-human transmission within Sierra Leone and find no evidence for import or export of EBOV across national borders after its initial introduction. Using high-depth replicate sequencing, we observe both host-to-host transmission and recurrent emergence of intrahost genetic variants. We trace the increasing impact of purifying selection in suppressing the accumulation of nonsynonymous mutations over time. Finally, we note changes in the mucin-like domain of EBOV glycoprotein that merit further investigation. These findings clarify the movement of EBOV within the region and describe viral evolution during prolonged human-to-human transmission. Copyright © 2015 The Authors. Published by Elsevier Inc.

    The aim of this study was to describe Norwegian healthcare staffs' experiences of participating in care of patients with Ebola virus disease in Sierra Leone. Ebola is one of the most feared viruses known. Ebola virus disease is highly contagious with high mortality. The few qualitative studies made on experiences among healthcare professionals have highlighted problems as lack of protective resources, insufficient personnel and risk of societal stigmatization. Descriptive study with qualitative approach. Individual narrative and focus group interviews were obtained during 2015 with eight nurses and one physician who had worked in Ebola care in Sierra Leone. The interviews were analysed using qualitative content analysis. The analysis resulted in the two themes: 'Experiencing security by learning to manage risks'; and 'Developing courage and growth by facing personal fears'. Subthemes were: 'Relying on safeguard actions', 'Managing risk of contagion', 'Developing strategies for care despite risks', 'Constantly reminded of death', 'Successively defeating fears' and last, 'Increasing motivation through meaningfulness'. The participants described the reliance on training, organized effort, strict guidelines and equipment. They were respectful of the risk of transmission, made risk assessments, took responsibility, handled risky situations and were reminded of suffering and death. Despite challenges, the hazardous work with Ebola virus disease patients was experienced as meaningful which was an important motivator. Safe care was central in working with Ebola patients, but the care relation was challenged. © 2016 John Wiley & Sons Ltd.

    To describe maternal and perinatal outcomes among pregnant women with suspected Ebola virus disease (EVD) in Sierra Leone. Observational investigation of maternal and perinatal outcomes among pregnant women with suspected EVD from five districts in Sierra Leone from June-December 2014. Suspected cases were ill pregnant women with symptoms suggestive of EVD or relevant exposures who were tested for EVD. Case frequencies and odds ratios were calculated to compare patient characteristics and outcomes by EVD status. There were 192 suspected cases: 67 (34.9%) EVD-positive, 118 (61.5%) EVD-negative, and 7 (3.6%) EVD status unknown. Women with EVD had increased odds of death (OR 10.22; 95% CI, 4.87-21.46) and spontaneous abortion (OR 4.93; 95% CI, 1.79-13.55) compared with those without EVD. Women without EVD had a high frequency of death (30.2%) and stillbirths (65.9%). One of 14 neonates born following EVD-negative and five of six neonates born following EVD-positive pregnancies died. EVD-positive and EVD-negative women with suspected EVD had poor outcomes, highlighting the need for increased attention and resources focused on maternal and perinatal health during an urgent public health response. Capturing pregnancy status in nationwide surveillance of EVD can help improve understanding of disease burden and design effective interventions. This article is protected by copyright.

    To evaluate how the extreme poverty of the patients and the poor salaries of the staff combined to increase the cost of treatment to patients within the subsidised national tuberculosis programme in Sierra Leone. From September to December of 1994, semi-structured interviews were conducted with 72 patients and 17 staff of the National Leprosy and Tuberculosis Control Programme of Sierra Leone, a screening and treatment programme funded by international donors. Although some extra costs were indeed incurred within the subsidized national tuberculosis treatment programme, they were much lower than those incurred during the pre-programme period when the patients sought intermittent help from a wide range of traditional and biomedical sources within the plural healing continuum. The national politico-economic crisis, and the consequent poverty of most patients, impeded compliance with and sustainability of treatment, even within the formal subsidised treatment programme. More money was spent by patients on treatment in the months/years preceding entry into the national tuberculosis programme. Many factors retarded entry, including poor communications, misinformation, malpractice by health professionals, and displacement resulting from chronic internal warfare. The war intensified all factors that predispose to tuberculosis and retarded access to treatment. Supra-programme cost, or 'corruption,' was minimal due to the poverty of health professionals, with a few salient exceptions.

    Since December 2013, West Africa has experienced the worst Ebola virus outbreak in recorded history. Of the 28,639 cases reported to the World Health Organization as of March 2016, nearly half (14,124) occurred in Sierra Leone. With a case fatality rate of approximately 40%, this outbreak has claimed the lives of 11,316 individuals. No FDA-approved vaccines or drugs are available to prevent or treat Ebola virus infection. Experimental vaccines and therapies are being developed; however, their safety and efficacy are still being evaluated. Therefore, there is an urgent need to develop control measures to prevent or limit future Ebola virus outbreaks.Previously, we developed a replication-defective Ebola virus that lacks the coding region for the essential viral transcription activator VP30 (Ebola ΔVP30 virus). Here, we evaluated the vaccine efficacy of Ebola ΔVP30 virus in a non-human primate model and describe our collaborative Ebola project in Sierra Leone.

    Climate change has implications for health, ecology and society. Urban green areas are a key element in the planning of cities, promoting citizen interaction with the environment, as well as health. Lack of planning and design of these areas as well as the selection of ornamental trees can be a trigger of pollen allergy in the surrounding population. Reforestation is among the programs implemented by the government that have an impact on allergy. Environmental reforestation programs do not take into account the allergenic potential of some species. In the last 4 years, the government of Nuevo Leon, Mexico, has planted nearly 18,000 Quercus species trees, in addition to an unknown number of Fraxinus species trees that are listed as tree species with high pollen production. To identify changes in tree pollen sensitization, based on environmental reforestation programs. A retrospective and descriptive study was done in which positive skin prick tests to pollen from trees in the interval of 2010-2014 were analyzed, correlating between tree species used for reforestation and increased sensitivity to the former. A statistically significant increase in pollen sensitization to species with which Nuevo Leon was reforested was found, along with a decrease in sensitization to the species that were not reforested. Reforestation contributes to some extent to the change in the pattern of positive skin tests and may result in more frequent exacerbations of respiratory diseases. It is an activity that should always be regulated and assisted by experts in the according field.

    The Mexican state of Nuevo Leon, located in the northeastern portion of the country, currently has 26 state and three federal nature reserves covering approximately 4.5% of its land area. These reserves were established for a variety of reasons not necessarily related to conservation purposes. In 2000 in response to a growing concern about the lack of organized conservation reserve planning to protect the important biological and physical features of Mexico, the Mexican Commission for Knowledge and Use of Biodiversity proposed 12 new terrestrial reserves for Nuevo Leon. The new reserves, if established, would increase the proportion of protected lands in the state to almost 24% of the state's land area. We compiled a Geographic Information System (GIS) analysis using digital thematic maps of physical and ecological features to examine how well the existing and proposed reserves incorporated the major biological and physical features of the state. The existing reserves are located primarily in regions with elevations > 1,000-1,500 m, on less productive soils, and are dominated by pine and oak forest cover types. As a result, the state's dominant biotic region - low elevation coastal plain with xeric scrub vegetation - is disproportionately under represented in the current reserve system. The new reserves would expand the protection of biophysical resources throughout the state. However, the inclusion of important resources in the low elevation coastal lands would still be limited.

    Ebola virus disease (EVD) in health workers (HWs) has been a major challenge during the 2014-2015 outbreak. We examined factors associated with Ebola virus exposure and mortality in HWs in Kenema District, Sierra Leone. We analyzed data from the Sierra Leone National Viral Hemorrhagic Fever Database, contact tracing records, Kenema Government Hospital (KGH) staff and Ebola Treatment Unit (ETU) rosters, and burial logs. From May 2014 through January 2015, 600 cases of EVD originated in Kenema District, including 92 (15%) HWs, 66 (72%) of whom worked at KGH. Among KGH medical staff and international volunteers, 18 of 62 (29%) who worked in the ETU developed EVD, compared with 48 of 83 (58%) who worked elsewhere in the hospital. Thirteen percent of HWs with EVD reported contact with EVD patients, while 27% reported contact with other infected HWs. The number of HW EVD cases at KGH declined roughly 1 month after implementation of a new triage system at KGH and the opening of a second ETU within the district. The case fatality ratio for HWs and non-HWs with EVD was 69% and 74%, respectively. The cluster of HW EVD cases in Kenema District is one of the largest ever reported. Most HWs with EVD had potential virus exposure both inside and outside of hospitals. Prevention measures for HWs must address a spectrum of infection risks in both formal and informal care settings as well as in the community. © 2016 World Health Organization; licensee Oxford Journals.

    Understanding the growth and spatial expansion of (re)emerging infectious disease outbreaks, such as Ebola and avian influenza, is critical for the effective planning of control measures; however, such efforts are often compromised by data insufficiencies and observational errors. Here, we develop a spatial-temporal inference methodology using a modified network model in conjunction with the ensemble adjustment Kalman filter, a Bayesian inference method equipped to handle observational errors. The combined method is capable of revealing the spatial-temporal progression of infectious disease, while requiring only limited, readily compiled data. We use this method to reconstruct the transmission network of the 2014-2015 Ebola epidemic in Sierra Leone and identify source and sink regions. Our inference suggests that, in Sierra Leone, transmission within the network introduced Ebola to neighbouring districts and initiated self-sustaining local epidemics; two of the more populous and connected districts, Kenema and Port Loko, facilitated two independent transmission pathways. Epidemic intensity differed by district, was highly correlated with population size (r = 0.76, p = 0.0015) and a critical window of opportunity for containing local Ebola epidemics at the source (ca one month) existed. This novel methodology can be used to help identify and contain the spatial expansion of future (re)emerging infectious disease outbreaks. © 2015 The Author(s).

    The paintings on the walls of the Cenador del Leon located in the gardens of the Real Alcazar in Seville next to the Pabellon de Carlos V in the Jardin Ingles area have been studied. The components of the wall paintings cross-sections, which were prepared using small samples taken from the walls of Cenador del Leon, were characterized using infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) analysis. The cross-sections of the collected samples indicated that the paint layer is well adhered to the preparation layer without any discontinuity, and only one carbonation layer exists at the top of the sequence of layers. These data suggest that the paint was applied on a fresco surface, and therefore, the adopted technique was fresco. Based on the different elements detected by EDX analysis of the cross-sections, the detected pigments included iron oxides accompanied by clay minerals (or earths) in the red pink, golden yellow and yellow colours, blue smelt for the blue colour and basic copper chloride (atacamite) for the green colour. In one sample, the particles were composed of Ba and S from barium sulphate and Ti and O from rutile titanium oxide due to a modern pigment.

    How traditional birth attendants (TBAs) in post-war Sierra Leone explain, handle and prevent postpartum haemorrhage (PPH) and their potential role in a better management of PPH to reduce maternal mortality in this low resource setting. Semi-quantitative interviews about knowledge and measures in PPH and participant observation with 140 Sierra Leonean birth attendants, divided in three groups: (A) TBAs who never attended any official training course (n = 82); (B) TBAs who attended at least one official training course (n = 48); and (C) officially trained birth attendants (n = 10). There are several observable gaps in the knowledge of TBAs about PPH compared to modern obstetrics, however similar procedures exist. Herbal medicine is applied; metaphysical convictions about PPH remain present. Training courses show an impact. Officially trained birth attendants demonstrate knowledge deficiencies and lack resources and infrastructure to manage PPH adequately. Morbidity and mortality of PPH in Sierra Leone is related to several factors and not solely to the ignorance of TBAs. TBAs still play an important role for many women there. Hence improvement of the formal health sector should be combined with life-saving programmes integrating TBAs in the care for the pregnant, delivering and breastfeeding mothers. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  9. Marginalization of girl mothers during reintegration from armed groups in Sierra Leone.

    Although the widespread presence of girls who participate in fighting forces is increasingly recognized, they remain a highly marginalized group globally, receiving little attention either during or after armed conflict. This is especially true for "girl mothers," girls who return to communities with children born while members of fighting forces. The concept of marginalization (Hall et al. 1994) is used to examine what happens to girl soldiers, especially girl mothers, in the aftermath of armed conflict when they seek to reintegrate back into their communities. This analysis, as part of a larger study of reintegration of girl mothers, is based on field work with girls who were in fighting forces in northwest Sierra Leone, especially those who returned with children. The type and level of marginalization these girls experience is consistent with the conceptualization of marginalization; however, they lack voice and experience shame and vulnerability. Moreover, economics were fundamentally related to their marginalization. The girls' access to resources was significantly constrained because the area was heavily impacted by the war and because of widespread poverty throughout Sierra Leone. The findings raise important questions about marginalization of girls affected by war. Girls and girl mothers experience an extremely high level of marginalization; however, some aspects are not consistent with the original conceptualization of marginalization. Theory development in nursing needs to incorporate multiple voices, especially those of the very marginalized and be done in such a manner that benefits and empowers.

    Full Text Available Ebola has provided the greatest test of the Sierra Leonean security sector – and, in turn, of the UK-led reforms of the past ten-to-fifteen years. The performance of the country's security forces at the height of the crisis suggests that there are sound structures in place; however, Ebola has shown that the Government of Sierra Leone's national security architecture still lacks maturity in responding to such a scenario. Drawing on first-hand interviews with advisers on the ground, this article explores the Sierra Leone government’s response to the Ebola crisis and the performance of the security sector so far, within the wider context of UK-led security-sector reform (SSR since the end of the civil war. In doing so, it highlights a number of lessons to have emerged from the crisis, exploring what these reveal about the nature of the reforms implemented since the end of the country's civil war. In turn, it explores what these suggest for future SSR, which continues to be a core component of the UK’s approach to development and overseas capacity-building.

    The biogas from bio-energy electrical power plant of Nuevo Leon represents, in all the national territory, the first experience on the advantage of biogas emitted by the sanitary landfills for the generation of electrical energy. Therefore, one of the specific objectives of this paper is the one of diffusion and reproduction of the same one in other cities of Mexico and Latin America. The project is framed within the world-wide policies on the control of emissions for the reduction of the greenhouse effect gases (GEG) and its impact in the global climatic change. The gas emitted by the trash sanitary landfills, commonly known as biogas, is a gas mixture derived from the decomposition of the organic matter of the municipal trash by microorganisms in anaerobic conditions. Biogas generated in the sanitary landfills has a methane content of 55% and a 35% of carbon dioxide. The balance 10% is made up of water steam, hydrogen, nitrogen, oxygen, hydrogen sulfur and other gases in minimum amounts. [Spanish] La Central Electrica de Biogas de Bioenergia de Nuevo Leon representa, en todo el territorio nacional, la primera experiencia sobre el aprovechamiento del biogas emitido por los rellenos sanitarios para la generacion de energia electrica.

    Childhood mortality is a stubborn problem and remains highest in Sub-Saharan Africa (SSA). Existing research on childhood mortality in SSA indicate that most of the childhood deaths are from preventable causes such as diarrhoea, pneumonia, measles, malaria, HIV and underlying malnutrition, acute respiratory infections, whooping cough, tuberculosis, bronchopneumonia, dirty feeding bottles and utensils, inadequate disposal of household refuse and poor storage of drinking water. However, insufficient attention has been given to maternal marital status and childhood mortality relationships. Understanding the implications of maternal marital status for childhood mortality can add to our knowledge of the correlates of neonatal and infant mortality and furnish insights to support the design and delivery of interventions to address the problem. To document and examine the extent to which the association between neonatal and infant mortality varies between single and ever-married mothers in Sierra Leone, Burkina Faso, and Burundi. A single mother is defined in this study as a woman who has either lived with a partner, married before, widowed, separated during the survey periods and has given at least one life birth. Ever-married woman is woman who has been married at least once in their lives although their current marital status may not be married. Data for this study were drawn from the latest Demographic and Health Surveys (DHS) in Burkina Faso, Sierra Leone and Burundi. The selected datasets came from 2010 Burkina Faso DHS (BFDHS), 2008 Sierra Leone DHS (SLDHS) and 2010 Burundi DHS (EDSB II). The relevant data for this study (women age 15-49 years who had at least one live birth within the five years preceding the survey) were extracted from the whole dataset of each country (Burkinabe (n = 17,087), Sierra Leonean (n = 7374) and Burundian (n = 9389). Univariate and multivariate statistical analyses were used to assess the association between neonatal and infant

    Prehospital care, including patient transport, is integral in the patient care process during the Ebola response. Transporting ill persons from the community to Ebola care facilities can stop community spread. Vehicles used for patient transport in infectious disease outbreaks should be evaluated for adequate infection prevention and control. An ambulance driver in Sierra Leone attributed his Ebola infection to exposure to body fluids that leaked from the patient compartment to the driver cabin of the ambulance. A convenience sample of 14 vehicles used to transport patients with suspected or confirmed Ebola in Sierra Leone were assessed. The walls separating the patient compartment and driver cabin in these vehicles were evaluated for structural integrity and potential pathways for body fluid leakage. Ambulance drivers and other staff were asked to describe their cleaning and decontamination practices. Ambulance construction and design standards from the National Fire Protection Association, US General Services Administration, and European Committee on Standardization (CEN) were reviewed. Many vehicles used by ambulance staff in Sierra Leone were not traditional ambulances, but were pick-up trucks or sport-utility vehicles that had been assembled or modified for patient transport. The wall separating the patient compartment and driver cabin in many vehicles did not have a waterproof seal around the edges. Staff responsible for cleaning and disinfection did not thoroughly clean bulk body fluids with disposable towels before disinfection of the patient compartment. Pressure from chlorine sprayers used in the decontamination process may have pushed body fluids from the patient compartment into the driver cabin through gaps around the wall. Ambulance design standards do not require a waterproof seal between the patient compartment and driver cabin. Sealing the wall by tightening or replacing existing bolts is recommended, followed by caulking of all seams with a

    Full Text Available Education should be considered as one of the mechanisms for governments and nations to succeed in a post-conflict process. The purpose of this Review Article is twofold: to explain the importance of education in a post-conflict setting, and to describe a few strategies that post-conflict societies have implemented. In terms of research design, a multiple case study approach has been implemented. The paper reviews a unique topic with specific reference to education plans implemented in post-conflict societies such as Liberia, Sierra Leone, and South Africa. Each of them has experienced violent conflicts and has used education as a tool to succeed in their post-conflict process. In sum, there are several educational programs that involve children, young people, survivors, parents, teachers, and local communities as well as curriculums focused on teaching of cultural values and technical skills to improve the quality of life in a post-conflict setting.

    Social scientists have long studied the patterns, motivations, and recidivism rates of sexual offenders; however, the majority of prior research has examined rape, where victims are assaulted by a single offender in isolated events. Often overlooked are sexually violent assaults committed during armed conflicts, which often exhibit group-level sexual offending. This oversight could be a result of perceived notions that sexual violence during conflict is a rare or regrettable event; however, it has been documented consistently throughout history. The purpose of this study was to improve our understanding of sexual violence during war by comparing and contrasting preconflict characteristics, conflict framing, and justifications for sexual violence in the Bosnian and Sierra Leone armed conflicts. This greater understanding can then be used to identify factors that may contribute to the collectivization of sexual violence during war.

    Full Text Available El presente texto cuestiona el utilitarismo de Jeremy Bentham como fundamento de la teoría marginalista walrasiana. La problemática se aborda a través de un análisis comparativo del pensamiento de Jeremy Bentham y de Leon Walras en tres áreas centrales: sus visiones de la sociedad y el objetivo social, sus aproximaciones teóricas y metodológicas en relación directa con sus respectivas teorías de la sociedad, y el lugar del principio de utilidad en el marco de las teorías generales de sociedad. El escrito contribuye a un debate vigente sobre los fundamentos filosóficos de la teoría de la elección racional y a deshomogenizar el pensamiento de los padres del marginalismo.

  2. Global health business: the production and performativity of statistics in Sierra Leone and Germany.

    Erikson, Susan L

    2012-01-01

    The global push for health statistics and electronic digital health information systems is about more than tracking health incidence and prevalence. It is also experienced on the ground as means to develop and maintain particular norms of health business, knowledge, and decision- and profit-making that are not innocent. Statistics make possible audit and accountability logics that undergird the management of health at a distance and that are increasingly necessary to the business of health. Health statistics are inextricable from their social milieus, yet as business artifacts they operate as if they are freely formed, objectively originated, and accurate. This article explicates health statistics as cultural forms and shows how they have been produced and performed in two very different countries: Sierra Leone and Germany. In both familiar and surprising ways, this article shows how statistics and their pursuit organize and discipline human behavior, constitute subject positions, and reify existing relations of power.

  3. Strategic environmental assessment of hydrological and irrigation plans in Castilla y Leon, Spain

    The study illustrates how strategic environmental assessment (SEA) can promote sustainable development plans. It defines and applies an SEA methodology to two draft plans: the hydrological plan for the Duero basin in Spain and the irrigation plan for the region of Castilla y Leon. Although prepared by national and regional authorities, respectively, both draft plans refer to the management and use of water as a resource for economic development and refer roughly to the same area. The SEA addresses the environmental, economic, and social impacts of the combined draft plans, using relevant indicators and objectives. The analysis shows that the proposals would lead to high financial costs and significant negative impacts on the environment for each job created; it develops and assesses a number of alternatives that would address these impacts. The results are used to define SEA procedures for the new Structural Funds period (2000--2006) and will provide a useful lesson for plans at all levels of government within Spain.

    This is a comprehensive book on the life and works of Leon Henkin (1921–2006), an extraordinary scientist and excellent teacher whose writings became influential right from the beginning of his career with his doctoral thesis on “The completeness of formal systems” under the direction of Alonzo Church. Upon the invitation of Alfred Tarski, Henkin joined the Group in Logic and the Methodology of Science in the Department of Mathematics at the University of California Berkeley in 1953. He stayed with the group until his retirement in 1991. This edited volume includes both foundational material and a logic perspective. Algebraic logic, model theory, type theory, completeness theorems, philosophical and foundational studies are among the topics covered, as well as mathematical education. The work discusses Henkin’s intellectual development, his relation to his predecessors and contemporaries, and his impact on the recent development of mathematical logic. It offers a valuable reference work for researcher...

  5. Territorial identity and landscape. Evolution morphology of nuclei in Castilla y Leon

    2015-01-01

    This paper aims to study the physical and socioeconomic transformations of rural settlements belonging to the Spanish region of Castile and Leon, throughout the second half of the 20th century. The evolution of urban form is analyzed, using a geographical information system (GIS) and calculating several shape metrics, and is then related to historical demographical data. The results are meant to show the effects of functional specialization, caused by the integration of rural regions in global economic hierarchies, on settlement structures and patterns. Gradual loss of the traditional features of Castilian villages, such as urban compactness and integration in the landscape, due to the disappearance or neglect of vernacular architecture and the construction of new industrial infrastructures, poses a risk for future place-based development policies. It is deemed necessary to preserve local identity and avoid destruction or degradation of the traditional heritage for revitalizing these territories. (Author)

  6. Deforestation in Gola Forest Region, Sierra Leone: Geospatial Evidence and a Rice Farmer's Expected Utility Analysis

    Abu-Kpawoh, John Christian

    Global land cover change constitutes the single major threat to ecological systems (Dale, 1997). These changes result from burning (Lavorel et al, 2007), agricultural expansion (Angelsen and Kaimowitz, 1999) and other activities triggered by socio-economic wants. Gola Rainforest National Park (GRNP) in Sierra Leone is under such threat from rice farmers. A 1926-gazetted demarcation established the park boundaries using stone landmarks, which was re-drawn in 1956 due to conflicting interests between the local communities and the British Colonial government. The increasing pressure from arable land-insecure population today has caused these gazetted landmarks to be overrun, compromising the efforts of the government and international organizations to protect the largest tract of forest in Sierra Leone. The incentive-driven interaction of competing land uses lead to inevitable land use change decisions in and around the park (Barbier, 1997), where the park is contextually a tract of forest cover surrounded by agricultural land. Evidence to date shows that land uses around the park have compromised the park's quality as a sustainable forest reserve in the last twenty-five years (1991 - 2016). A major conservation problem relates to forest-edge communities need for arable land to practice their dominant slash-and-burn agriculture. We conduct geospatial analysis from Landsat images and show that there is land cover conversion in the region for the period 1991 - 2016. We hypothesize that rice farmers have driven this conversion. These farmers are risking penalties stipulated in the 2012 NPAA Act to convert forests to agricultural land. Using Erdas Imagine and ArcGIS Pro, we classify two Landsat images (January 1991 and April 2016). We obtain overall accuracy of 88% and 95% for the 1991 and 2016 classifications respectively, which contains four land cover classes, including water, forest, other vegetation/secondary vegetation, and bare land. The quantitative result of this

    Worldwide, over one billion children and adolescents live in war-affected settings. At present, only limited research has investigated linkages between disrupted social ecology and adverse mental health outcomes among war-affected youth. In this study, we examine three community-level characteristics - social disorder and collective efficacy within the community, as reported by caregivers, and perceived stigma as reported by youth - in relation to externalizing behaviors and internalizing symptoms among male and female former child soldiers in postconflict Sierra Leone. A total of 243 former child soldiers (30% female, mean age at baseline: 16.6 years) and their primary caregivers participated in interviews in 2004 and 2008, as part of a larger prospective cohort study of war-affected youth in Sierra Leone. Two-point growth models were estimated to examine the relationship between community-level characteristics and externalizing and internalizing outcomes across the time points. Both social disorder within the community, reported by caregivers, and perceived stigma, reported by youth, positively covaried with youths' externalizing and internalizing scores - indicating that higher levels of each at baseline and follow-up were associated with higher levels of mental health problems at both time points (p mental health outcomes was nonsignificant (p > .05). This study offers a rare glimpse into the role that the postconflict social context plays in shaping the mental health among former child soldiers. Results indicate that both social disorder and perceived stigma within the community demonstrate an important relationship to externalizing and internalizing problems among adolescent ex-combatants. Moreover, these relationships persisted over a 4-year period of follow-up. These results underscore the importance of the postconflict social environment and the need to develop postconflict interventions that address community-level processes in addition to the needs

    Full Text Available Background: Physical differences among human populations may lead to variable prevalence of skin disorders in different ethnicities. Skin infections are one of the important curable and largely preventable categories of skin disorders in the communities. Aim: The purpose of the study was to see the patterns of skin infections in black Africans of Sierra Leone and to compare with other ethnic populations. Materials and Methods: Local blacks of all age groups presenting in Dermatology out patient department of Pak Field Hospital (established as a part of UN peacekeeping mission in Sierra Leone were included (from Nov 2004 to Oct 2005. Relevant clinical history and physical examination was done. Laboratory investigations were carried out when indicated. Skin diseases were broadly classified into two major categories i.e., infective and noninfective. Among infective, sexually transmitted infections were again separated. Nonblack settlers in the area and UN troops were not included in the study. Data was recorded and analyzed by Microsoft Excel program. Results: 3011 patients belonging to different local tribes having a variety of skin disorders were seen. Patients were of all ages and both sexes ranging from one month to 73 years of age. The Infective skin disorders were seen in 61.7% patients and most prevalent were superficial fungal infections (41.2% followed by, sexually transmitted infections (9.9% and parasitic infections (6.5%. Bacterial and viral infections were rare and so was the scabies. More than 90% parasitic infections were onchocerciasis with full spectrum of cutaneous manifestations. Conclusion: Pattern of skin infections in blacks varies considerably from other ethnic races. Environmental factors, geographical location and free existence of vector for onchocerciasis in West African region, possibly have a significant influence in this variable prevalence.

    Background. Thousands of people have survived Ebola virus disease (EVD) during the ongoing outbreak. However, data about the frequency and risk factors of long-term post-EVD complications remain scarce. We describe the clinical characteristics of EVD survivors followed in a survivor clinic in Freetown, Sierra Leone. Methods. A survivor clinic opened within an Ebola treatment center compound in Freetown, Sierra Leone. At each visit, clinical and psychological assessments were conducted and free treatment was offered. Survivors were referred to a partner's hospitals if their condition could not be managed in the clinic. We used routinely collected data from the clinic to describe long-term complications of EVD and their risk factors. Results. A total of 1001 medical consultations for 166 patients were performed between 3 February and 21 June 2015. The most frequent complaints and diagnoses were arthralgia (n = 129 [77.7%]), fatigue (n = 116 [69.8%]), abdominal pain (n = 90 [54.2%]), headache (n = 87 [52.4%]), anemia (n = 83 [50%]), skin disorders (n = 81 [48.8%]), back pain (n = 54 [32.5%]), and alopecia (n = 53 [31.9%]). Ocular complications were diagnosed in 94 survivors (56.7%); uveitis was the most common (n = 57 [34%]). Survivors were 10 times more likely to develop uveitis post-EVD if they presented with red/injected eyes during the acute phase of their illness. Conclusions. Post-EVD complications among our patients were similar to those described previously and were detected early following the acute phase of disease. Follow-up of survivors should begin immediately after discharge to address sequelae as they arise and reduce the potential for development of long-term disabilities such as blindness. PMID:27001797

    To conduct a needs assessment for emergency obstetric care (EmOC) to address the unacceptably high maternal and newborn mortality indices in Sierra Leone 8 years after the end of the civil war. From June to August 2008, a cross-sectional survey was conducted of health facilities in Sierra Leone offering delivery services. Assessment tools were local adaptations of tools developed by the Averting Maternal Death and Disability program at Columbia University, New York, USA. There were enough comprehensive EmOC (CEmOC) facilities in the country but they were poorly distributed. There were no basic EmOC (BEmOC) facilities. Few facilities (37% of hospitals and 2% of health centers) were able to perform assisted vaginal delivery (AVD), and 3 potentially BEmOC facilities did not meet the standard only because they did not perform AVD. Severe shortages in staff, equipment, and supplies, and unsatisfactory supply of utilities severely hampered the delivery of quality EmOC services. Demand for maternity and newborn services was low, which may have been related to the poor quality and the high/unpredictable out-of-pocket cost of such services. Significant increases in the uptake of institutional delivery services, the linkage of remote health workers to the health system, and the recruitment of midwives, in addition to rapid expansion in the training of health workers (including training in midwifery and obstetric surgery skills), are urgently needed to improve the survival of mothers and newborns.

    This study aimed to determine the prevalence, determinants and pattern of herbal medicine use among hypertensive patients in Freetown. We conducted a cross-sectional study among hypertensive patients attending public and private health facilities in Freetown, Sierra Leone between August and October 2016. We analyzed the data using SPSS version 24. We used Chi-square, Fisher exact two-tailed test and regression analysis for data analysis. A p-value less than 0.05 was considered statistically significant. Out of 260 study participants, over half (n = 148, 56.9%) reported using herbal medicine for the treatment of hypertension alone or together with comorbid condition(s). The most commonly used herbal medicine among users were honey (n = 89, 33.3%), moringa (n = 80, 30.0%) and garlic (n = 73, 27.3%). No significant difference existed between users and non-users of herbal medicine with regards to socio-demographic and health-related factors. The majority (n = 241, 92.7%) of respondents considered herbal medicine beneficial if it was recommended by a healthcare provider yet 85.1% (n = 126) did not disclose their herbal medicine use to their health care provider. There is a high use of herbal medicines among hypertensive patients in Freetown, Sierra Leone. It is essential for healthcare providers to take heed of the findings of this study and routinely ask their patients about their herbal medicine use status. Such practice will provide the opportunity to discuss the benefits and risks of herbal medicine use with the aim of maximizing patient desired therapeutic outcomes. Copyright © 2018 Elsevier Ltd.

    The West African Ebola epidemic of 2013–2016 was by far the largest outbreak of the disease on record. Sierra Leone suffered nearly half of the 28,646 reported cases. This paper presents a set of culturally contextualized Ebola messages that are based on the findings of qualitative interviews and focus group discussions conducted in 'hotspot' areas of rural Bombali District and urban Freetown in Sierra Leone, between January and March 2015. An iterative approach was taken in the message development process, whereby (i) data from formative research was subjected to thematic analysis to identify areas of community concern about Ebola and the national response; (ii) draft messages to address these concerns were produced; (iii) the messages were field tested; (iv) the messages were refined; and (v) a final set of messages on 14 topics was disseminated to relevant national and international stakeholders. Each message included details of its rationale, audience, dissemination channels, messengers, and associated operational issues that need to be taken into account. While developing the 14 messages, a set of recommendations emerged that could be adopted in future public health emergencies. These included the importance of embedding systematic, iterative qualitative research fully into the message development process; communication of the subsequent messages through a two-way dialogue with communities, using trusted messengers, and not only through a one-way, top-down communication process; provision of good, parallel operational services; and engagement with senior policy makers and managers as well as people in key operational positions to ensure national ownership of the messages, and to maximize the chance of their being utilised. The methodological approach that we used to develop our messages along with our suggested recommendations constitute a set of tools that could be incorporated into international and national public health emergency preparedness and

    People with disabilities have the right to personal mobility and available and affordable assistive technology, according to the Convention of Rights of Persons with Disabilities. The aims were to investigate similarities and differences between Sierra Leone and Malawi concerning participants' mobility and satisfaction with their lower-limb prosthetic or orthotic device and related service delivery, and to identify variables associated with patients' satisfaction with assistive devices and associated services in the entire study group from these two low-income countries. Questionnaires, including QUEST, were answered by 222 patients in Sierra Leone and Malawi. Eighty-six per cent of assistive devices were in use, but half needed repair. One third of participants reported pain when using their assistive device. A higher percentage (66%) of participants in Sierra Leone had difficulties or could not walk at all on uneven ground compared with 42% in Malawi. The majority in both countries had difficulties or could not walk at all up and down hills, or on stairs. Participants in both countries were quite satisfied (mean 3.7-3.9 of 5) with their assistive device. Participants were most dissatisfied with: comfort (46%), dimensions (39%), and safety (38%) of their assistive device. In Sierra Leone participants were less satisfied than in Malawi with service delivery (mean 3.7; 4.4, p < .001). Access to repairs and servicing of their assistive device was considered the most important item. In Sierra Leone patients were less satisfied with follow-up services (41%) than patients in Malawi were (22%). The strongest association with satisfaction with assistive device was pain, and for satisfaction with service, country. The general condition of devices and the ability to walk on uneven ground were associated with both satisfaction with assistive devices and service received. Participants reported high levels of use and mobility with their assistive device, in spite of pain

    Filarial infection is endemic in the tropics and is a public health problem in Africa, Asia, South and Central America, and the Pacific Islands. Co-infection with filarial nematodes, if unrecognized, can result in untoward therapeutic consequences. We report a case of co-infection of Wuchereria bancrofti and Onchocerca volvulus that was diagnosed by direct blood smear (W. bancrofti ) and serology (O. volvulus) in a native of Sierra Leone. We comment briefly on the therapeutic implications of the co-infection.

    Introduction The availability of healthful foods varies by neighborhood. We examined the availability and price of more healthful foods by store type, neighborhood income level, and racial composition in a community with high rates of diet-related illness and death. Methods We used the modified Nutrition Environment Measures Survey in Stores to conduct this cross-sectional study in 2008. We surveyed 73 stores (29% supermarkets, 11% grocery stores, and 60% convenience stores) in Leon County, F...

    At the end of the eleven-year conflict in Sierra Leone, a wide range of policies were implemented to address both demand- and supply-side constraints within the healthcare system, which had collapsed during the conflict. This study examines the extent to which households' exposure to financial risks associated with seeking healthcare evolved in post-conflict Sierra Leone. This study uses the 2003 and 2011 cross-sections of the Sierra Leone Integrated Household Survey to examine changes in catastrophic health expenditure between 2003 and 2011. An Oaxaca-Blinder decomposition approach is used to quantify the extent to which changes in catastrophic health expenditure are attributable to changes in the distribution of determinants (distributional effect) and to changes in the impact of these determinants on the probability of incurring catastrophic health expenditure (coefficient effect). The incidence of catastrophic health expenditure decreased significantly by 18% from approximately 50% in 2003 t0 32% in 2011. The decomposition analysis shows that this decrease represents net effects attributable to the distributional and coefficient effects of three determinants of catastrophic health expenditure - ill-health, the region in which households reside and the type of health facility used. A decrease in the incidence of ill-health and changes in the regional location of households contributed to a decrease in catastrophic health expenditure. The distributional effect of health facility types observed as an increase in the use of public health facilities, and a decrease in the use of services in facilities owned by non-governmental organizations (NGOs) also contributed to a decrease in the incidence of catastrophic health expenditure. However, the coefficient effect of public health facilities and NGO-owned facilities suggests that substantial exposure to financial risk remained for households utilizing both types of health facilities in 2011. The findings support the

    Chicken pox is a mainly childhood contagious disease caused by the Varicella Zoster Virus which gives rise to major healthcare and social costs. In 2005, Castile and Leon added chicken pox vaccine injections to its childhood vaccination schedule for eleven year-olds subject to coming down with this disease. This strategy does not modify the major mobility generated thereby at younger ages. This study is aimed at evaluating the profitability of systematic vaccination for chicken pox in infants 15 months of age in Castile and Leon. An economic cost-benefit evaluation has been set out by jeans of a decision-making tree. A fictitious cohort of 100,000 children in Castile and Leon having reached 15 months of age in 2004 is studied, to whom the chicken pox vaccine would be administered in conjunction with the mumps, measles, rubella vaccines. This study is approached from the social standpoint. The time horizon selected was that of up until the study cohort was to reach 15 years of age, applying a 3% discount rate. A sensitivity analysis was made for evaluating the uncertainty of some variables... The cost-benefit ratio of adding this vaccine to the childhood vaccination schedule amounts to 1.23. From the social standpoint, administering chicken pox vaccine in conjunction with the mumps, measles, rubella vaccines show itself to be profitable. The profitability is modified both if a second dose of vaccine is added as well as if only the direct healthcare costs are analyzed.

  3. Diamonds, a resource curse? The case of Kono District in Sierra Leone

    Wilson, Sigismond Ayodele

    Using an actor-oriented approach to political ecology integrated with theory on the social production of scale, this dissertation examines the extent to which diamond exploitation constitutes a resource curse in Sierra Leone, with Kono District as a case-study. It uses social survey methods and remote sensing analysis of Landsat images to (1) evaluate the role of Sierra Leone's diamonds in economic development from a historical lens, (2) examine the extent to which a weak regulatory state apparatus makes a rich diamond endowment more of a curse than a blessing, (3) determine whether geographically diffuse and remotely-located diamonds are more a liability than an asset, and (4) assess whether environmental conditions are worse in diamond than in non-diamond chiefdoms. Results of the study showed that the contribution of diamonds to national economic growth declined precipitously following the politicization of diamonds and growing informalization of mining under the leadership of Siaka Stevens. Growing disenchantment combined with grievances over access to diamond resources and rights, culminating in a civil war fuelled by conflict diamonds. Findings indicated that actors capitalized on a weak regulatory state to fulfill their agendas. Illicit diamond exploitation was mainly driven by corruption, economic constraints and perverse economic incentives. Preferential land allocation to industrial mining following World Bank Group-directed national mining policy reforms and the weakness of the state in ensuring companies' adherence to mining clauses precipitated corporation-community conflicts. Study findings showed that the resource curse was acute on diggers who received less than 1 a day unlike their South American counterparts who made at least 7 daily. Results from the study demonstrate that the spatiality of diamonds also contributed to the resource curse. Illicit diamond mining was more acute in remotely located mining sites than in extractive sites closer to

    The number of maternal deaths in sub-Saharan Africa continues to be overwhelmingly high. In West Africa, Sierra Leone leads the list, with the highest maternal mortality ratio. In 2010, financial barriers were removed as an incentive for more women to use available antenatal, delivery and postnatal services. Few published studies have examined the quality of free antenatal services and access to emergency obstetric care in Sierra Leone. A cross-sectional survey was conducted in 2014 in all 97 peripheral health facilities and three hospitals in Bombali District, Northern Region. One hundred antenatal care providers were interviewed, 276 observations were made and 486 pregnant women were interviewed. We assessed the adequacy of antenatal and delivery services provided using national standards. The distance was calculated between each facility providing delivery services and the nearest comprehensive emergency obstetric care (CEOC) facility, and the proportion of facilities in a chiefdom within 15 km of each CEOC facility was also calculated. A thematic map was developed to show inequities. The quality of services was poor. Based on national standards, only 27% of women were examined, 2% were screened on their first antenatal visit and 47% received interventions as recommended. Although 94% of facilities provided delivery services, a minority had delivery rooms (40%), delivery kits (42%) or portable water (46%). Skilled attendants supervised 35% of deliveries, and in only 35% of these were processes adequately documented. None of the five basic emergency obstetric care facilities were fully compliant with national standards, and the central and northernmost parts of the district had the least access to comprehensive emergency obstetric care. The health sector needs to monitor the quality of antenatal interventions in addition to measuring coverage. The quality of delivery services is compromised by poor infrastructure, inadequate skilled staff, stock-outs of

    Since the most ancient times, hospital constructions and progresses in the clinical practice advanced pari passu. We can find exampless of this statement in Greek regions as well as in Greek citie overseas. Thus, during the renaissance, great figures ot that time converged in Italy: The genius Leonardo da Vinci (1452-1519) and Leon Battista Alberti (1404-1472), a humanist and innovator of architecture. Michelangelo Buonarroti (1475-1564) and his contemporany artists performed anatomical dissection to perfect their art by studying the human body. Anatomical studies flourished at the University of Padua, driven by the Flemish Master. Based on the rigorous study of the anatomical substrate, the studies on the function of the already known organic structures excelled in the xvii century. That century started with the revelation of the major blood circulation by the British physician William Harvey, alumni of the University of Padua, and continued with the description of the minior or pulmonary circulation by ancient or contemporany authors and of the peripheral connections between the arterial and the venous system (Marcelo Malpighi, 1661). All these researchers, and others, were membres of the University of Padua, were the beneficial influence of the teachings of Galileo persisted. In the following centuries, together with the embryological and normal anatomy, the pathological anatomy, systematized by G.B. Morgani, became the cornerstone of the clinical practice. The model of the ancient hospitals evolved to ward the National Institutes of Health in Mexico fostered by Dr. Ignacio Chávez. Copyright © 2014 Instituto Nacional de Cardiología Ignacio Chávez.

    Available phosphorus (P) and nitrogen (NP) generally occur in very low amounts in soils of the tropics and subtropics. Under such conditions, most crops would require the addition of N and P fertilizer. This is not possible for small-scale farmers who cannot afford or have limited access to fertilizers, and therefore depend on low-input cropping systems. The selection of cultivars adapted to low soil nutrient conditions would sustain the production levels of subsistence farmers. Experiments were therefore conducted over a five-year period to identify cowpea cultivars with high phosphorus use efficiency and nitrogen fixation. Two of such cultivars-IT86D-1010 and IT86D-719 have been identified. Root morphological characteristics such as root length, root fineness and vesicular-arbuscular mycorrhizae are responsible for high P uptake and use efficiency. Multilocational testing of the cultivars showed that they cannot do well in areas with low rainfall. They have been distributed to farmers through the extension services for large scale production in southern Sierra Leone. (author). 28 refs, 4 figs, 6 tabs

    Full Text Available The current outbreak of Ebola Virus Disease in Upper West Africa is the largest ever recorded. Molecular evidence suggests spread has been almost exclusively through human-to-human contact. Social factors are thus clearly important to understand the epidemic and ways in which it might be stopped, but these factors have so far been little analyzed. The present paper focuses on Sierra Leone, and provides cross sectional data on the least understood part of the epidemic-the largely undocumented spread of Ebola in rural areas. Various forms of social networking in rural communities and their relevance for understanding pathways of transmission are described. Particular attention is paid to the relationship between marriage, funerals and land tenure. Funerals are known to be a high-risk factor for infection. It is suggested that more than a shift in awareness of risks will be needed to change local patterns of behavior, especially in regard to funerals, since these are central to the consolidation of community ties. A concluding discussion relates the information presented to plans for halting the disease. Local consultation and access are seen as major challenges to be addressed.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Burgos, Soria and Segovia of the Comunidad Autonoma de Castilla-Leon.

    The characterization of plant genetic resources has a significant impact on their possible future use in lentil breeding programs and also, in the activity of germplasm collections. In this work we have characterized 27 lentil landraces from the region of Castilla and Leon (plateau in Northern Spain), existing among them two different morphological groups according to the characteristics of the seeds (Macrosperma and Microsperma). Fifteen morpho-agronomical characters were measured for data collection. A principal components analysis allowed the definition of the 5 factors which explain 83.7% of the cumulative variance. The first factor explains 25.3% of total variation and it is related to seed production. We performed a cluster analysis obtaining 5 groups, each one defined by the average values of the employed characters. 37.0% of landraces were included in group 5, characterized by a high mean of the harvest index (38.4) and also a high mean value (74.4) for the number of pods. To study the seeds we used a correspondence analysis 6 dimensions which explained the 80.9% of the variance were chosen. Two cluster analysis were carried out using the coordinates of the aforementioned analysis. The aim of this work was to study the morphological variability of these populations and to discover the relationship among them. (author)

  11. Short Report: Serological Evidence of Under-Reported Dengue Circulation in Sierra Leone.

    Full Text Available Dengue virus (DENV is thought to have emerged from a sylvatic cycle in Africa but has since become adapted to an urban-centric transmission cycle. These urban areas include villages in West Africa where DENV is not often routinely considered for patients presenting with febrile illnesses, as other endemic diseases (malaria, Lassa fever, e.g. present with similar non-specific symptoms. Thus, dengue is likely under diagnosed in the region. These plaque reduction neutralization test-50 (PRNT50 screening results of patients presenting with fevers of unknown origin (FUO at a clinic in Kenema, Sierra Leone indicate that all four serotypes of DENV likely circulate in areas surrounding Kenema. Using a more conservative PRNT80 cut-off value, our results still indicate the presence of antibody to all four serotypes in the region. Identifying alternate etiologies of FUOs in this region will assist clinicians in plan-of-care decisions as well as follow-up priorities. This is particularly relevant given the Ebola outbreak in the region, where diagnosis has a range of downstream effects ranging from correct allocation of medical resources, appropriate isolation of patients, and ultimately, a better informed public health sector.

  12. Measuring work engagement among community health workers in Sierra Leone: Validating the Utrecht Work Engagement Scale

    Full Text Available This study examines the concept of volunteer work engagement in a sample of 334 community health workers in Bonthe District, Sierra Leone. Structural equation modelling was used to validate both the 9-item and the 17-item Utrecht Work Engagement Scale (UWES-9 and UWES-17, respectively. Results assessing the UWES-17 invalidated the three-factor structure within this cohort of community health workers, as high correlations were found between latent factors. Findings for the validity of the UWES-9 were largely consistent with those of the UWES-17. Model fit for the UWES-9 were generally equivalent for the one-factor, three-factor, and bifactor solutions, however the three-factor model was once again rejected due to high factor correlations. Based on these results, the current sample provides evidence that work engagement is best represented as a unidimensional construct in this context. Findings are considered alongside previous research to offer support for the utilization of the shortened UWES-9 in this context, as it appears to provide a good representation of work engagement and possess a parsimonious unidimensional scoring scheme.

    2015-06-01

    Full Text Available In the last decade, the Sierra Leone’s diamond mines have been the focus of an intense debate among analysts and experts of the development. Two main interrelated issues have been at stake in this debate: first, to understand the economic and political reasons that had supported the civil war from 1991 to 2002 and, second, to understand how to convert a potential “conflict commodity” in a resource for peace and prosperity. In this paper, I intend to highlight some recurring stereotypes of this debate. In particular, I will focus on a constellation of representations that depict the artisanal miners either as workers poorly organized and prone to irrational economic behavior, or as workers subjected to forms of exploitation akin to slavery. Based on fieldwork conducted in the diamond mining areas of Sierra Leone (2007-2011, this article intends to analyze the main forms of working organization and distribution of earnings among the miners. By challenging some stereotypes characterizing the development discourse, my aim is to show the cultural complexity and the historical density of the practices through which the miners face the risks and uncertainties of their job.

    We rapidly assessed the health of Ebola virus disease (EVD) survivors in Kenema, Sierra Leone, by reviewing medical charts of all patients attending the Survivor Clinic of Kenema Government Hospital. Data were abstracted on signs and symptoms at every attendance. As of November 2015, a total of 621 attendances by 115 survivors with laboratory-confirmed EVD were made to the Survivor Clinic. Most (60.9%) survivors were women. Survivors' median age was 28 years (range 0.25-70 years). Survivors attended the clinic a median of 5 times (range 1-21 times) each, and the median time from EVD discharge to attendance was 261 days (range 4-504 days). The most commonly reported signs and symptoms among the 621 attendances were headache (63.1%), fever (61.7%), and myalgia (43.3%). Because health needs of EVD survivors are complex, rapid chart reviews at survivor clinics should be repeated regularly to assess the extent of illness and prioritize service delivery.

    During the 2014 Ebola virus disease (EVD) outbreak, less than half of EVD-suspected cases were laboratory tested as Ebola virus (EBOV)-negative, but disease identity remained unknown. In this study we investigated the etiology of EVD-like illnesses in EBOV-negative cases. From November 13, 2014 to March 16, 2015, EVD-suspected patients were admitted to Jui Government Hospital and assessed for EBOV infection by real-time PCR. Of 278 EBOV negative patients, 223 (80.21%), 142 (51.08%), 123 (44.24%), 114 (41.01%), 59 (21.22%), 35 (12.59%), and 12 (4.32%) reported fever, headache, joint pain, fatigue, nausea/vomiting, diarrhea, hemorrhage, respectively. Furthermore, 121 (43.52%), 44 (15.83%), 36 (12.95%), 33 (11.87%), 23 (8.27%), 10 (3.60%) patients were diagnosed as infection with malaria, HIV, Lassa fever, tuberculosis, yellow fever, and pneumonia, respectively. No significant differences in clinical features and symptoms were found between non-EVD and EVD patients. To the best of our knowledge, the present study is the first to explore the etiology of EVD-like illnesses in uninfected patients in Sierra Leone, highlighting the importance of accurate diagnosis to EVD confirmation.

    Large private sector investments in low- and middle-income countries are often critically evaluated with regards to their environmental, social, human rights, and health impacts. A health impact assessment, including a baseline health survey, was commissioned by the Addax Bioenergy Sierra Leone project in 2010. As part of the monitoring, a follow-up survey was conducted three years later. A set of health indicators was assessed at six impacted and two control sites. Most of these indices improved, particularly at the impacted sites. The prevalences of stunting, wasting, and Plasmodium falciparum in children under five years of age decreased significantly at impacted sites (all p < 0.05) and non-significantly at control sites. Anemia in children and in women of reproductive age (15–49 years) decreased significantly at impacted and control sites (p < 0.05 and p < 0.001, respectively). Health facility-based deliveries increased significantly at the impacted sites (p < 0.05). The prevalences of helminth infections in children aged 10–15 years remained approximately at the same levels, although focal increases at the impacted sites were noted. Access to improved sanitation decreased significantly (p < 0.05) at control and non-significantly at impacted sites. Water quality remained poor without significant changes. The epidemiologic monitoring of a bioenergy project provides a useful contribution for evidence-based decision-making. PMID:25514152

    Full Text Available The Iberian Peninsula presents the highest number of wildfires in Europe. In the NW of Spain in particular, wildfires are the natural risk with the greatest economic impact in this region. Wildfires caused by lightning are closely related to the triggering of convective phenomena. The prediction of thunderstorms is a very complex task because these weather events have a local character and are highly dependent on mesoscale atmospheric conditions. The development of convective storms is directly linked to the existence of a synoptic environment favoring convection. The aim of this study is to classify the atmospheric patterns that provide favorable environments for the occurrence of wildfires caused by lightning in the region of Castile and Leon, Spain. The database used for the study contains 376 wildfire days from the period 1987–2006. NCEP data reanalysis has been used. The atmospheric fields used to characterise each day were: geopotential heights and temperatures at 500 hPa and 850 hPa, relative humidity and the horizontal wind at 850 hPa. A Principal Component Analysis in T-mode followed by a Cluster Analysis resulted in a classification of wildfire days into five clusters. The characteristics of these clusters were analysed and described, focusing particularly on the study of those wildfire days in which more than one wildfire was detected. In these cases the main feature observed was the intensification of the disturbance typical of the cluster to which the wildfire belongs.

    Northwest of Mexico City, the study area is located in the State of Guanajuato. Leon Valley has covered with groundwater its demand of water, estimated in 20.6 cubic meters per second. The constant increase of population and economic activities in the region, mainly in cities and automobile factories, has also a constant growth in water needs. Related extraction rate has produced an average decrease of approximately 1.0 m per year over the past two decades. This suggests that the present management of the groundwater should be checked. Management of groundwater in the study area involves the possibility of producing environmental impacts by extraction. This vital resource under stress becomes necessary studying its hydrogeological functioning to achieve scientific management of groundwater in the Valley. This research was based on the analysis and integration of existing information and the field generated by the authors. On the base of updated concepts like the geological structure of the area, the hydraulic parameters and the composition of deuterium-delta and delta-oxygen -18, this research has new results. This information has been fully analyzed by applying a groundwater flow model with particle tracking: the result has also a similar result in terms of travel time and paths derived from isotopic data.

    Environmental and breathing-zone samples were analyzed for azodicarbonamide, benzene, styrene, and toluene at Leon Plastics, Grand Rapid, Michigan in March and May 1983, and March 1984. The evaluation was requested to investigate occupational exposures to chemical agents, particularly in the injection molding department. Sixteen employees were interviewed. Azodicarbonamide concentrations ranged from undetectable to 280 micrograms per cubic meter (microg/m/sup 3/) in May 1983, and from undetectable to 752 microg/m/sup 3/ in March 1984. There is no federal standard for azodicarbonamide. The concentrations of the other substances were below their relevant standards. Ammonia, styrene, and triphenylphosphate were identified as pyrolysis products above the azodicarbonamide presses. Symptoms of eye, nose and throat irritation, coughing, and wheezing were reported. Pulmonary-function test results could not be linked to azodicarbonamide exposures. The authors conclude that exposure to azodicarbonamide is the probable cause of the reported symptoms. Recommendations include using engineering controls and appropriate work practices to minimize exposure to azodicarbonamide.

    The Texas Department of State Health Services issued fish consumption advisories in 2003 and 2010 for Leon Creek in San Antonio, Texas, based on elevated concentrations of polychlorinated biphenyls (PCBs) in fish tissues. The U.S. Geological Survey (USGS) measured elevated PCB concentrations in stream-sediment samples collected during 2007–9 from Leon Creek at Lackland Air Force Base (now known as Joint Base San Antonio-Lackland; the sampling site at this base is hereinafter referred to as the “Joint Base site”) and sites on Leon Creek downstream from the base. This report describes the occurrence and concentrations of selected trace elements and halogenated organic compounds (pesticides, flame retardants, and PCBs) and potential sources of PCBs in stream-sediment samples collected from four sites on Leon Creek during 2012–14. In downstream order, sediment samples were collected from Leon Creek at northwest Interstate Highway 410 (Loop 410), Rodriguez Park, Morey Road, and Joint Base. The USGS periodically collected streambed-sediment samples during low flow and suspended-sediment samples during high flow.

    We examined the possible relationships between pollutant concentrations and mortality at seven different locations of Castilla-Leon, Spain, and the relationships between such concentration levels and emergency admissions (morbidity) at four hospitals in the region, taking into account the possible masking effect of other atmospheric variables. The study was based on daily mortality and morbidity data from 1995 to 1997 (ICD-9 codes: 390-459 cardiovascular; 460-519 respiratory; 520-579 digestive causes); moreover, data for meteorological variables (air temperature, relative humidity, solar radiation, atmospheric pressure and wind velocity) and air pollution data (SO{sub 2}, O{sub 3}, NO, NO{sub 2} and CO) were used. A minimum set of weather and pollutant predictors was selected using forward inclusion stepwise linear regression methods and these were used to produce a multivariate model of the different causes of mortality and morbidity. For the whole period, the mortality attributable to cardiovascular causes had an incidence higher than the mortality due to respiratory and digestive causes. The frequency distributions corresponding to the different diseases as classified by ages revealed that the population older than 69 is the most affected, the proportion of cardiovascular disease related deaths in this age sector being 7-fold higher than for the rest of the groups. Mortality and morbidity due to respiratory and cardiovascular-related diseases showed a high correlation coefficient with temperature, solar radiation and ozone, and in general significant correlations were also seen with SO{sub 2}.

    Chromium (Cr) is a contaminant commonly found in surface and groundwater. In nature Cr commonly occurs in two valences: Cr(VI) is highly mobile, toxic and carcinogenic, while Cr(III) is less mobile. Cr was first detected in groundwater in the Leon Valley region (located in central Mexico) in 1975 (Rodriguez and Armienta, 1995). Previous work proposed an anthropogenic origin for a high concentration plume near the industrial Buenavista (BV), while the larger sub ppb plume located near San Juan de Otates (SJO) is assumed to be caused by weathering of the SJO pyroxenite. Cr stable isotopes have been shown to be useful in monitoring reduction and can also be used to infer redox and transport conditions in natural settings and the goals of our research are: 1) use stable isotope values (δ53Cr) to monitor Cr behavior in the Leon Valley, 2) identify sources (industrial vs. weathering of ultramafic rocks). Since 1975, the highly contaminated BV area is showing a decrease in groundwater Cr(VI) concentrations. Our sampling in 2007 show Cr(VI) concentrations decreasing from 0.005mg/l to 121mg/l to 0.002mg/l to 95.1mg/l. However, the Cr waste piles still exit and Cr(VI) concentrations from leachate collection ponds range from 1.2g/l to 6.8g/l. Isotopic values obtained from leaching experiments performed on the waste pile samples show enriched δ53Cr values (0.76‰ to 3.25‰) either indicating varying reduction or that the waste is fractionated during the ore processing. δ53Cr values for groundwater range from 0.33‰ to 0.46‰, indicating minimal reduction and lack of available reducing agents. The lack of variation of isotopic values seen in the groundwater plume is also consistent with the results of previous studies showing insignificant fractionation due to sorption within the plume (Villalobos-Aragon et al., 2008). The unfractionated Cr(VI) in groundwater vs. those of the waste piles, considered the contamination source, suggests that either 1) the Cr in the waste

    Full Text Available Studies of children with atypical emotional experience demonstrate that childhood exposure to high levels of hostility and threat biases emotion perception. This study investigates emotion processing, in former child soldiers and non-combatant civilians. All participants have experienced prolonged violence exposure during childhood. The study, carried out in Sierra Leone, aimed to examine the effects of exposure to and forced participation in acts of extreme violence on the emotion processing of young adults war survivors. A total of 76 young, male adults (38 former child soldier survivors and 38 civilian survivors were tested in order to assess participants’ ability to identify four different facial emotion expressions from photographs and movies. Both groups were able to recognize facial expressions of emotion. However, despite their general ability to correctly identify facial emotions, participants showed a significant response bias in their recognition of sadness. Both former soldiers and civilians made more errors in identifying expressions of sadness than in the other three emotions and when mislabeling sadness participants most often described it as anger. Conversely, when making erroneous identifications of other emotions, participants were most likely to label the expressed emotion as sadness. In addition, while for three of the four emotions participants were better able to make a correct identification the greater the intensity of the expression, this pattern was not observed for sadness. During movies presentation the recognition of sadness was significantly worse for soldiers. While both former child soldiers and civilians were found to be able to identify facial emotions, a significant response bias in their attribution of negative emotions was observed. Such bias was particularly pronounced in former child soldiers. These findings point to a pervasive long-lasting effect of childhood exposure to violence on emotion processing

  7. Potential Impact of Sexual Transmission on Ebola Virus Epidemiology: Sierra Leone as a Case Study.

    Full Text Available Sexual transmission of Ebola virus disease (EVD 6 months after onset of symptoms has been recently documented, and Ebola virus RNA has been detected in semen of survivors up to 9 months after onset of symptoms. As countries affected by the 2013-2015 epidemic in West Africa, by far the largest to date, are declared free of Ebola virus disease (EVD, it remains unclear what threat is posed by rare sexual transmission events that could arise from survivors.We devised a compartmental mathematical model that includes sexual transmission from convalescent survivors: a SEICR (susceptible-exposed-infectious-convalescent-recovered transmission model. We fitted the model to weekly incidence of EVD cases from the 2014-2015 epidemic in Sierra Leone. Sensitivity analyses and Monte Carlo simulations showed that a 0.1% per sex act transmission probability and a 3-month convalescent period (the two key unknown parameters of sexual transmission create very few additional cases, but would extend the epidemic by 83 days [95% CI: 68-98 days] (p < 0.0001 on average. Strikingly, a 6-month convalescent period extended the average epidemic by 540 days (95% CI: 508-572 days, doubling the current length, despite an insignificant rise in the number of new cases generated.Our results show that reductions in the per sex act transmission probability via abstinence and condom use should reduce the number of sporadic sexual transmission events, but will not significantly reduce the epidemic size and may only minimally shorten the length of time the public health community must maintain response preparedness. While the number of infectious survivors is expected to greatly decline over the coming months, our results show that transmission events may still be expected for quite some time as each event results in a new potential cluster of non-sexual transmission. Precise measurement of the convalescent period is thus important for planning ongoing surveillance efforts.

    Contact tracing in an Ebola virus disease (EVD) outbreak is the process of identifying individuals who may have been exposed to infected persons with the virus, followed by monitoring for 21 days (the maximum incubation period) from the date of the most recent exposure. The goal is to achieve early detection and isolation of any new cases in order to prevent further transmission. We performed a retrospective data analysis of 261 probable and confirmed EVD cases in the national EVD database and 2525 contacts in the Contact Line Lists in Kenema district, Sierra Leone between 27 April and 4 September 2014 to assess the performance of contact tracing during the initial stage of the outbreak. The completion rate of the 21-day monitoring period was 89% among the 2525 contacts. However, only 44% of the EVD cases had contacts registered in the Contact Line List and 6% of probable or confirmed cases had previously been identified as contacts. Touching the body fluids of the case and having direct physical contact with the body of the case conferred a 9- and 20-fold increased risk of EVD status, respectively. Our findings indicate that incompleteness of contact tracing led to considerable unmonitored transmission in the early months of the epidemic. To improve the performance of early outbreak contact tracing in resource poor settings, our results suggest the need for prioritized contact tracing after careful risk assessment and better alignment of Contact Line Listing with case ascertainment and investigation.This article is part of the themed issue 'The 2013-2016 West African Ebola epidemic: data, decision-making and disease control'. © 2017 The Author(s).

    Full Text Available The recent phenomenon of large-scale acquisition of land for a variety of investment purposes has raised deep concerns over the food security, livelihood and socio-economic development of communities in many regions of the developing world. This study set out to investigate the food security outcomes of land acquisitions in northern Sierra Leone. Using a mixture of quantitative and qualitative research methods, the study measures the severity of food insecurity and hunger, compares the situation of food security before and after the onset of operations of a land investing company, analyzes the food security implications of producing own food versus depending on wage labour for household food needs, and evaluates initiatives put in place by the land investing company to mitigate its food insecurity footprint. Results show an increase in the severity of food insecurity and hunger. Household income from agricultural production has fallen. Employment by the land investing company is limited in terms of the number of people it employs relative to the population of communities in which it operates. Also, wages from employment by the company cannot meet the staple food needs of its employees. The programme that has been put in place by the company to mitigate its food insecurity footprint is failing because of a host of reasons that relate to organization and power relations. In conclusion, rural people are better off producing their own food than depending on the corporate structure of land investment companies. Governments should provide an enabling framework to accommodate this food security need, both in land investment operations that are ongoing and in those that are yet to operate.

  10. Reductions in inpatient mortality following interventions to improve emergency hospital care in Freetown, Sierra Leone.

    Matthew Clark

    Full Text Available BACKGROUND: The demand for high quality hospital care for children in low resource countries is not being met. This paper describes a number of strategies to improve emergency care at a children's hospital and evaluates the impact of these on inpatient mortality. In addition, the cost-effectiveness of improving emergency care is estimated. METHODS AND FINDINGS: A team of local and international staff developed a plan to improve emergency care for children arriving at The Ola During Children's Hospital, Freetown, Sierra Leone. Following focus group discussions, five priority areas were identified to improve emergency care; staff training, hospital layout, staff allocation, medical equipment, and medical record keeping. A team of international volunteers worked with local staff for six months to design and implement improvements in these five priority areas. The improvements were evaluated collectively rather than individually. Before the intervention, the inpatient mortality rate was 12.4%. After the intervention this improved to 5.9%. The relative risk of dying was 47% (95% CI 0.369-0.607 lower after the intervention. The estimated number of lives saved in the first two months after the intervention was 103. The total cost of the intervention was USD 29 714, the estimated cost per death averted was USD 148. There are two main limitation of the study. Firstly, the brevity of the study and secondly, the assumed homogeneity of the clinical cases that presented to the hospital before and after the intervention. CONCLUSIONS: This study demonstarted a signficant reductuion in inpatient mortality rate after an intervention to improve emergency hospital care If the findings of this paper could be reproduced in a larger more rigorous study, improving the quality of care in hospitals would be a very cost effective strategy to save children's lives in low resource settings.

    Full Text Available Inland valleys are becoming increasingly important agricultural production areas for rural households in sub-Saharan Africa due to their relative high and secure water availability and soil fertility. In addition, inland valleys are important as water buffer and biodiversity hot spots and they provide local communities with forest, forage, and fishing resources. As different inland-valley ecosystem functions may conflict with agricultural objectives, indiscriminate development should be avoided. This study aims to analyze the diversity of inland valleys in Sierra Leone and to develop guidelines for more precise interventions. Land use, biophysical and socio-economic data were analyzed on 257 inland valleys using spatial and multivariate techniques. Five cluster groups of inland valleys were identified: (i semi-permanently flooded with high soil organic carbon (4.2% and moderate available phosphorus (10.2 ppm, mostly under natural vegetation; (ii semi-permanently flooded with low soil organic carbon (1.5% and very low available phosphorus (3.1 ppm, abandoned by farmers; (iii seasonally flooded with moderate soil organic carbon (3.1% and low available phosphorus (8.3 ppm, used for rainfed rice and off-season vegetables produced without fertilizer application for household consumption and market; (iv well drained with moderate soil organic carbon (3.8% and moderate available phosphorus (10.0 ppm, used for rainfed rice and off-season vegetables produced with fertilizer application for household consumption and market; and (v well drained with moderate soil organic carbon (3.6% and moderate available phosphorus (11 ppm, used for household consumption without fertilizer application. Soil organic carbon, available phosphorus, hydrological regime, physical accessibility and market opportunity were the major factors affecting agricultural intensification of inland valleys. Opening up the areas in which inland valleys occur through improved roads and

    Full Text Available Organizations are among the preferred outlets women use both to voice societal prejudices against them and to showcase their potential for rural/community development. There is an increasing advocacy for gender equality, women’s empowerment and the integration of women folks into the socio-economic, political and cultural fabrics of society. Girl-child education and women-based capacity building programs such as micro-finance, entrepreneurship, political activism, etc. have surfaced prominently on these women’s empowerment efforts. In this study, a questionnaire-driven survey is conducted in two districts in southern Sierra Leone. The survey covers 36 influential women in 36 town-level communities in the country. The study analyzes the personal and organization characteristics of the women in relation to social perceptions and rural/community development. A large percent of the women surveyed are educated, married and belong to social organizations. In addition to other social/development organizations, women’s organizations are also present in each of the surveyed communities. Most of the women organizations are local in nature and operate entirely on funds raised from within the local communities. This display of organizational ability of the surveyed rural women shows a significant perceptional shift towards recognizing women folks as productive counterparts in our societies. This trend also psychologically strengthens the women community to take on tangible responsibilities that were ones meant for men only. The analysis also shows that rural women hold managerial and other administrative positions in the organizations which are strongly oriented towards various forms of rural/community development. This is a significant positive deviation from the traditional perception which has unduly confined the women folks to the backyard for centuries now. This trend not only has the potential of benefiting the millions more women languishing in

    Analysis of aboveground biomass and carbon stocks (as equivalent CO{sub 2}) was performed in the Castilla y Leon region, Spain. Data from the second and third Spanish Forest Inventories (1996 and 2006) were used. Total aboveground biomass was calculated using allometric biomass equations and biomass expansion factors (BEF), the first method giving higher values. Forests of Castilla y Leon stored 77,051,308 Mg of biomass, with a mean of 8.18 Mg ha{sup -1}, in 1996 and 135,531,737 Mg of biomass, with a mean of 14.4 Mg ha{sup -1}, in 2006. The total equivalent CO{sub 2} in this region's forests increased 9,608,824 Mg year{sup -1} between 1996 and 2006. In relation to the Kyoto Protocol, the Castilla y Leon forests have sequestered 3 million tons of CO{sub 2} per year, which represents 6.4% of the total regional emission of CO{sub 2}. A Geographic Information System (GIS) based method was also used to assess the geographic distribution of residual forest biomass for bio-energy in the region. The forest statistics data on area of each species were used. The fraction of vegetation cover, land slope and protected areas were also considered. The residual forest biomass in Castilla y Leon was 1,464,991 Mg year{sup -1}, or 1.90% of the total aboveground biomass in 1996. The residual forest biomass was concentrated in specific zones of the Castilla y Leon region, suitable for the location of industries that utilize biomass as energy source. The energy potential of the residual forest biomass in the Castilla y Leon region is 7350 million MJ per year. (author)

    To investigate the Western Area Surge (WAS) program in the Ebola outbreak of Sierra Leone, and to analyze its implementing effect. The subject of this study was 3,813 laboratory confirmed Ebola hemorrhagic fever (EHF) cases reported in Sierra Leone from November 19, 2014 through January 27, 2015, a period before and after the implementation of the WAS program. To analyze and make conclusions according to the working experience of China Mobile Laboratory Reponses Team in the fight of Ebola outbreak, using WHO published EHF case definition to make diagnosis and compare the number of bed numbers, confirmed EHF cases, samples tested, and positive rates before and after implementation of WAS program. From the implementation of WAS program on 17th December 2014 to half a month later, the total numbers of Ebola holding and treatment centers increased from 640 to 960, six additional laboratories were established. On January, 2015, another two laboratories from America and The Netherlands were established. The numbers of samples tested one month before and after WAS program were 7,891 and 9,783, respectively, with an increase of 24.0 percent, while the positive rate of Ebola virus decreased from 22.2% (1,752/7,891) to 11.0% (1,077/9,783). The positive rate of blood samples decreased from 39.6% (248/626) in the month before WAS program to 27.4% (131/478) (χ2=17.93, P<0.001) in the mother after WAS program, the positive rate of blood samples 22.7% (103/454) to 10% (62/609) (χ2=31.03, P<0.001), accordingly. After 3 weeks of WAS program, in addition to Western Area, another four hotspots in Sierra Leone had also reported a significant decrease of the numbers of confirmed EVD cases. Forty-two days after implementation of WAS program, the daily number of laboratory confirmed EHF cases decreased from 63 to 10. WAS program played a vital role in controlling the EHF outbreak rapidly in Sierra Leone. It could also provide guidance for the control similar large infectious diseases

    Most underdeveloped countries do not meet core disease outbreak surveillance because of the lack of human resources, laboratory and infrastructural facilities. The use of cell phone technology for disease outbreak syndromic surveillance is a new phenomenon in Sierra Leone despite its successes in other developing countries like Sri Lanka. In this study we set to evaluate the effectiveness of using cell phone technology for Ebola hemorrhagic fever syndromic surveillance in a high risked community in Sierra Leone. This study evaluated the effectiveness of using cell phone messaging (text and calls) for community Ebola hemorrhagic fever syndromic surveillance in high risked community in southern Sierra Leone. All cell phone syndromic surveillance data used for this study was reported as cell phone alert messages-texts and voice calls; by the Moyamba District Health Management Team for both Ebola hemorrhagic fever suspect and mortalities. We conducted a longitudinal data analysis of the monthly cumulative confirmed Ebola hemorrhagic fever cases and mortalities collected by both the traditional sentinel and community cell phone syndromic surveillance from August 2014 to October 2014. A total of 129 and 49 Ebola hemorrhagic fever suspect and confirmed cases respectively were recorded using the community Ebola syndromic surveillance cell phone alert system by the Moyamba District Health Management Team in October 2014. The average number of Ebola hemorrhagic fever suspects and confirmed cases for October 2014 were 4.16 (Std.dev 3.76) and 1.58 (Std.dev 1.43) respectively. Thirty-four percent (n=76) of the community Ebola syndromic surveillance cell phone alerts that were followed-up within 24 hours reported Ebola hemorrhagic fever suspect cases while 65.92% (n=147) reported mortality. Our study suggests some form of underreporting by the traditional sentinel Ebola hemorrhagic fever disease surveillance system in Moyamba District southern Sierra Leone for August

    Full Text Available Hispanic clinicians in Texas, United States of America, and in the neighboring state of Nuevo Leon, Mexico, were surveyed to determine their educational needs in the area of HIV/AIDS. Two-thirds of the 74 Texan and 22% of the 104 Mexican physicians queried had seen at least one HIV/AIDS patient in the previous year. The majority of the respondents were primary care physicians who: 1 were in private practice; 2 saw more than 1 000 patients per year; 3 had been out of training for more than 10 years; 4 provided some HIV prevention education to patients based on their perceived risk of infection; 5 rated their own knowledge of HIV/AIDS as average but rated their knowledge of treatments for the disease below average; 6 received most of their information about HIV/AIDS from journals rather than formal continuing education programs; 7 thought Hispanic patients had special needs with regard to HIV/AIDS care; and 8 were willing to attend education programs to improve their HIV/AIDS management skills. The greatest barriers to caring for HIV patients were lack of clinical knowledge and fear of infection. These results point to a need for a large-scale training program to improve the HIV/AIDS management skills of Hispanic clinicians in Texas and Nuevo Leon.

  17. Iodine Status of Women of Reproductive Age in Sierra Leone and Its Association with Household Coverage with Adequately Iodized Salt

    Full Text Available Salt iodization programs are a public health success in tackling iodine deficiency. Yet, a large proportion of the world’s population remains at risk for iodine deficiency. In a nationally representative cross-sectional survey in Sierra Leone, household salt samples and women’s urine samples were quantitatively analyzed for iodine content. Salt was collected from 1123 households, and urine samples from 817 non-pregnant and 154 pregnant women. Household coverage with adequately iodized salt (≥15 mg/kg iodine was 80.7%. The median urinary iodine concentration (UIC of pregnant women was 175.8 µg/L and of non-pregnant women 190.8 µg/L. Women living in households with adequately iodized salt had higher median UIC (for pregnant women: 180.6 µg/L vs. 100.8 µg/L, respectively, p < 0.05; and for non-pregnant women: 211.3 µg/L vs. 97.8 µg/L, p < 0.001. Differences in UIC by residence, region, household wealth, and women’s education were much smaller in women living in households with adequately iodized salt than in households without. Despite the high household coverage of iodized salt in Sierra Leone, it is important to reach the 20% of households not consuming adequately iodized salt. Salt iodization has the potential for increasing equity in iodine status even with the persistence of other risk factors for deficiency.

    In May 2012, the twice-yearly Maternal and Child Health Week (MCHW) integrated vitamin A supplementation (VAS) and supplementary measles vaccination to reach all children 6-59 months in Sierra Leone. Following the MCHW, a post event coverage survey was conducted to validate VAS coverage and assess adverse events following immunization. Using the WHO Expanded Program on Immunization sampling methodology, 30 clusters were randomly selected using population proportionate to size sampling. Fourteen caregivers of children 6-59 months were interviewed per cluster for precision of ±5%. Responses were collected via mobile phones using EpiSurveyor. Overall VAS and measles coverage was 91.9% and 91.6%, respectively, with no significant differences by age group, sex, religion or occupation. Major reasons given for not receiving VAS and measles vaccination were not knowing about the MCHW or being out of the area. Significantly more mild adverse events (fever, pain at injection site) were reported via the post event coverage survey (29.1%) than MCHW (0.01%) (p90% of children in Sierra Leone with equitable coverage. Increased reporting of mild adverse events during the survey may be attributed to delayed onset after measles vaccination and/or direct inquiry from enumerators. Even mild adverse events following immunization requires strengthened reporting during and after vaccination campaigns. © The Author 2014.

To determine forms of female genital mutilation (FGM), assess consistency between self-reported and observed FGM status, and assess the accuracy of Demographic and Health Surveys (DHS) FGM questions in Sierra Leone. Methods. This cross-sectional study, conducted between October 2010 and April 2012, enrolled 558 females aged 12–47 from eleven antenatal clinics in northeast Sierra Leone. Data on demography, FGM status, and self-reported anatomical descriptions were collected. Genital inspection confirmed the occurrence and extent of cutting. Results. All participants reported FGM status; 4 refused genital inspection. Using the WHO classification of FGM, 31.7% had type Ib; 64.1% type IIb; and 4.2% type IIc. There was a high level of agreement between reported and observed FGM prevalence (81.2% and 81.4%, resp.). There was no correlation between DHS FGM responses and anatomic extent of cutting, as 2.7% reported pricking; 87.1% flesh removal; and 1.1% that genitalia was sewn closed. Conclusion. Types I and II are the main forms of FGM, with labia majora alterations in almost 5% of cases. Self-reports on FGM status could serve as a proxy measurement for FGM prevalence but not for FGM type. The DHS FGM questions are inaccurate for determining cutting extent. PMID:24204384

    Malaria remains a significant cause of morbidity and mortality in West Africa, but the contribution of other vector-borne infections (VBIs) to the burden of disease has been understudied. We used rapid diagnostic tests (RDTs) for three VBIs to test blood samples from 1,795 febrile residents of Bo City, Sierra Leone, over a 1-year period in 2012-2013. In total, 24% of the tests were positive for malaria, fewer than 5% were positive for markers of dengue virus infection, and 39% were positive for IgM directed against chikungunya virus (CHIKV) or a related alphavirus. In total, more than half (55%) of these febrile individuals tested positive for at least one of the three VBIs, which highlights the very high burden of vector-borne diseases in this population. The prevalence of positives on the Chikungunya IgM and dengue tests did not vary significantly with age ( P > 0.36), but higher rates of malaria were observed in children Chikungunya IgM RDTs were moderately correlated with rainfall ( r 2 = 0.599). Based on the high prevalence of positive results on the Chikungunya IgM RDTs from individuals Bo and its environs, there is a need to examine whether an ecological shift toward a greater burden from CHIKV or related alphaviruses is occurring in other parts of Sierra Leone or the West African region.

    Full Text Available This paper attempts to investigate the lack of knowledge attitude and practices of street food vendors in Bo the Southern Province of Sierra Leone. A cross sectional study conducted among eighty-seven respondents vendors in forty-four in Bo City. Data was collected using a structured and semi structured questionnaire. The collected data is analysed using a simple descriptive statistics with the help Excel Microsoft ware. A statistical significance was found in relation to knowledge. Attitude towards food safety was negative self-reported practices by Street Food Vendors were statistically significant with low hygiene standards while predisposing factors showed relatively low personal hygiene poor environmental sanitation and low food safety practice. The realize consequences are utmost health risks of consuming street foods as food contamination has caused food borne diseases and outbreaks. It is recommended that standard training be provided for these vendors by the Bo City Council in collaboration with Njala University. It is essential that poor people in a developing country such as Sierra Leone be allowed to earn their livelihood by means of an easy-to-enter business such as street food vending when hygiene standards are sustained.

    While substantial research has examined the effects of pornography on young people in developed societies, existing studies fall short in addressing how sexually-explicit material affects young people in developing countries. The importance of such knowledge increases as the globalising effects of technology expand young peoples' access and exposure to pornography. During the summer of 2012, a study was undertaken in Sierra Leone examining factors affecting young peoples' sexual and reproductive health. The research assessed the influence of HIV knowledge, communication about sex, civil war and contraception myths on sexual behaviours, while remaining open to unanticipated factors. During data collection, respondents identified pornography, also called blues, as an influential factor, detailing its newfound accessibility driven by improved access to information and communication technologies in the country. Respondents also addressed several presumed ways in which pornography impacts young peoples' decisions about sexual health. The following study examines perceived effects of young peoples' exposure to pornography based on existing literature. It then outlines the findings of research conducted in Sierra Leone, drawing on primary data from the respondents and relevant published literature and concludes with proposals for addressing its negative effects.

    The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers and the San Antonio River Authority, configured, calibrated, and tested a Hydrological Simulation Program ? FORTRAN watershed model for the approximately 238-square-mile Leon Creek watershed in Bexar County, Texas, and used the model to simulate streamflow and water quality (focusing on loads and yields of selected constituents). Streamflow in the model was calibrated and tested with available data from five U.S. Geological Survey streamflow-gaging stations for 1997-2004. Simulated streamflow volumes closely matched measured streamflow volumes at all streamflow-gaging stations. Total simulated streamflow volumes were within 10 percent of measured values. Streamflow volumes are greatly influenced by large storms. Two months that included major floods accounted for about 50 percent of all the streamflow measured at the most downstream gaging station during 1997-2004. Water-quality properties and constituents (water temperature, dissolved oxygen, suspended sediment, dissolved ammonia nitrogen, dissolved nitrate nitrogen, and dissolved and total lead and zinc) in the model were calibrated using available data from 13 sites in and near the Leon Creek watershed for varying periods of record during 1992-2005. Average simulated daily mean water temperature and dissolved oxygen at the most downstream gaging station during 1997-2000 were within 1 percent of average measured daily mean water temperature and dissolved oxygen. Simulated suspended-sediment load at the most downstream gaging station during 2001-04 (excluding July 2002 because of major storms) was 77,700 tons compared with 74,600 tons estimated from a streamflow-load regression relation (coefficient of determination = .869). Simulated concentrations of dissolved ammonia nitrogen and dissolved nitrate nitrogen closely matched measured concentrations after calibration. At the most downstream gaging station, average simulated monthly

    Clinical and laboratory data were collected and analysed from patients with Ebola virus disease (EVD) in Jui Government Hospital in Freetown, Sierra Leone, where patients with EVD were received and/or treated from October 1, 2014 to March 21, 2015 during the West Africa EVD outbreak. The study admitted 285 patients with confirmed EVD and followed them up till the endpoint (recovery or death). EVD was confirmed by quantitative RT-PCR assays detecting blood Ebola virus (EBOV). Among the 285 lab-confirmed EVD cases in Jui Government Hospital, 146 recovered and 139 died, with an overall survival rate of 51.23 %. Patients under the age of 6 years had a lower survival rate (37.50 %). Most non-survivors (79.86 %) died within 7 days after admission and the mean hospitalization time for non-survivors was 5.56 ± 6.11 days. More than half survivors (63.69 %) turned blood EBOV negative within 3 weeks after admission and the mean hospitalization time for survivors was 20.38 ± 7.58 days. High blood viral load (≥10 6 copies/ml) was found to be predictive of the non-survival outcome as indicated by the Receiver Operating Characteristic (ROC) curve analysis. The probability of patients' survival was less than 15 % when blood viral load was greater than 10 6 copies/ml. Multivariate analyses showed that blood viral load (P = 0.005), confusion (P = 0.010), abdominal pain (P = 0.003), conjunctivitis (P = 0.035), and vomiting (P = 0.004) were factors independently associated with the outcomes of EVD patients. Most death occurred within 1 week after admission, and patients at the age of 6 or younger had a lower survival rate. Most surviving patients turned blood EBOV negative within 1-4 weeks after admission. Factors such as high blood viral load, confusion, abdominal pain, vomiting and conjunctivitis were associated with poor prognosis for EVD patients.

    Full Text Available Abstract Background Since 2007 Sierra Leone has conducted mass drug administration (MDA for the elimination of lymphatic filariasis (LF implemented by unpaid community health volunteers (CHVs. Other health campaigns such as Mother and Child Health Weeks (MCHW pay for services to be implemented at community level and these persons are then known as community health workers (CHWs. In 2010, the LF MDA in the 12 districts of the Southern, Northern and Eastern Provinces un-expectantly coincided with universal distribution of Long Lasting Insecticide Treated Nets (LLITNs during the MCHW. In-process monitoring of LF MDA was performed to ensure effective coverage was attained in hard to reach sites (HTR in both urban and rural locations where vulnerable populations reside. Methods Independent monitors interviewed individuals eligible for LF MDA and tallied those who recalled having taken ivermectin and albendazole, calculated program coverage and reported results daily by phone. Monitoring of coverage in HTR sites in the 4 most rapidly urbanizing towns was performed after 4 weeks of LF MDA and again after 8 weeks throughout all 12 districts. End process monitoring was performed in randomly selected HTR sites not previously sampled throughout all 12 districts and compared to coverage calculated from the pre-MDA census and reported treatments. Results Only one town had reached effective program coverage (≥80% after 4 weeks following which CHWs were recruited for LF MDA in all district headquarter towns. After 8 weeks only 4 of 12 districts had reached effective coverage so LF MDA was extended for a further month in all districts. By 12 weeks effective program coverage had been reached in all districts except Port Loko and there was no significant difference between those interviewed in communities versus households or by sex. Effective epidemiological coverage (≥65% was reported in all districts and overall was significantly higher in males versus

    The recent outbreak of the Ebola virus disease (EVD) in Sierra Leone has been characterized by the World Health Organization as one of the most challenging EVD outbreaks to date. The first confirmed case in Sierra Leone was a young woman who was admitted to a government hospital in Kenema following a miscarriage on 24 May 2014. On 5 January 2015, intensified training for an EVD response project was initiated at the medical university of Sierra Leone in Jui. To understand the knowledge, attitudes, practices, and perceived risk of EVD among the public, especially after this training, a rapid assessment was conducted from 10 to 16 March 2015. Interviews were conducted with 466 participants based on questionnaires that were distributed from 10 to 16 March 2015 by cluster sampling in three adjacent communities, namely Jui, Grafton, and Kossoh Town, in the Western Area Rural District of Sierra Leone. It was found that knowledge about EVD was comprehensive and high. Positive attitude towards prevention was found to be satisfactory. Nearly all participants knew the reporting phone number 117 and had reported some change in behavior since learning about Ebola. More than half (62 %) of the participants had a history of travelling to urban areas, which increases the risk of infection. The multivariable logistic regression analysis showed that community and occupation were variables associated with perceived risk of EVD. Our study showed that community level social mobilization and community engagement were an effective strategy in the special context.

    Sierra Leone is one of three countries recently affected by Ebola. In debates surrounding the circumstances that contributed to the initial failure to contain the outbreak, the word 'trust' is often used: In December 2014, WHO director Margret Chan used 'lack of trust in governments'; The Lancet's Editor-in-Chief, wrote how Ebola has exposed the '… breakdown of trust between communities and their governments.' This article explores the lack of trust in public healthcare providers in Sierra Leone, predating the Ebola outbreak, apparently linked to widespread petty corruption in primary healthcare facilities. It compares four NGO-supported accountability interventions targeting Sierra Leone's primary health sector. Field research was conducted in Kailahun, Kono and Tonkolili Districts, based on interviews with health workers and focus group discussions with primary healthcare users. Field research showed that in most clinics, women and children entitled to free care routinely paid for health services. A lack of accountability in Sierra Leone's health sector appears pervasive at all levels. Petty corruption is rife. Understaffing leads to charging for free care in order to pay clinic-based 'volunteers' who function as vaccinators, health workers and birth attendants. Accountability interventions were found to have little impact on healthworker (mis)behaviour. © The Author 2015.

     To assess the frequency of fatal recrudescence from Ebola virus disease after discharge from treatment centres, and explore the influence of infecting dose on case fatality rates.  Retrospective cohort study.  Western Area, Sierra Leone.  151 survivors treated for Ebola virus disease at the Kerry Town treatment centre and discharged. Survivors were followed up for a vital status check at four to nine months after discharge, and again at six to 13 months after discharge. Verbal autopsies were conducted for four survivors who had died since discharge (that is, late deaths). Survivors still living in Western Area were interviewed together with their household members. Exposure level to Ebola virus disease was ascertained as a proxy of infecting dose, including for those who died.  Risks and causes of late death; case fatality rates; odds ratios of death from Ebola virus disease by age, sex, exposure level, date, occupation, and household risk factors.  Follow-up information was obtained on all 151 survivors of Ebola virus disease, a mean of 10 months after discharge. Four deaths occurred after discharge, all within six weeks: two probably due to late complications, one to prior tuberculosis, and only one after apparent full recovery, giving a maximum estimate of recrudescence leading to death of 0.7%. In these households, 395 people were reported to have had Ebola virus disease, of whom 227 died. A further 53 people fulfilled the case definition for probable disease, of whom 11 died. Therefore, the case fatality rate was 57.5% (227/395) for reported Ebola virus disease, or 53.1% (238/448) including probable disease. Case fatality rates were higher in children aged under 2 years and adults older than 30 years, in larger households, and in infections occurring earlier in the epidemic in Sierra Leone. There was no consistent trend of case fatality rate with exposure level, although increasing exposure increased the risk of Ebola virus disease.  In this study of

    Mites of the genus Euseius are generally considered specialist as pollen feeders. Euseius alatus DeLeon is one of the six species of phytoseiid mites most commonly found on coconut plants in northeast Brazil associated with Aceria guerreronis Keifer. Although the morphology of E. alatus does not favor the exploitation of the meristematic area of the fruit inhabited by A. guerreronis, the predator may have some role in the control of this eriophyid during the dispersion process. The objective of this work was to evaluate the development and reproduction of E. alatus on the following diets: A. guerreronis, Ricinus communis pollen (Euphorbiaceae), and Tetranychus urticae Koch (Tetranychidae) + R. communis pollen + honey solution 10%. Euseius alatus developed slightly faster and had slightly higher oviposition rate when feeding on the diet composed of T. urticae + pollen + honey. However, life table parameters were very similar on all diets, suggesting that E. alatus may contribute in reducing the population of A. guerreronis in the field. (author)

    We performed Ebola virus disease diagnosis and viral load estimation for Ebola cases in Sierra Leone during the late stage of the 2014-2015 outbreak (January-March 2015) and analyzed antibody and cytokine levels and the viral genome sequences. Ebola virus disease was confirmed in 86 of 1001 (9.7%) patients, with an overall case fatality rate of 46.8%. Fatal cases exhibited significantly higher levels of viral loads, cytokines, and chemokines at late stages of infection versus early stage compared with survivors. The viruses converged in a new clade within sublineage 3.2.4, which had a significantly lower case fatality rate. © The Author 2017.

    Using histories of household members of Ebola virus disease (EVD) survivors in Sierra Leone, we calculated risk of EVD by age and exposure level, adjusting for confounding and clustering, and estimated relative risks. Of 937 household members in 94 households, 448 (48%) had had EVD. Highly correlated with exposure, EVD risk ranged from 83% for touching a corpse to 8% for minimal contact and varied by age group: 43% for children 60% for adults >30 years of age. Compared with risk for persons 20–29 years of age, exposure-adjusted relative risks were lower for those 5–9 (0.70), 10–14 (0.64), and 15–19 (0.71) years of age but not for children <2 (0.92) or 2–4 (0.97) years of age. Lower risk for 5–19-year-olds, after adjustment for exposure, suggests decreased susceptibility in this group. PMID:27144428

We found a higher rate of bleeding manifestations than reported elsewhere during the outbreak. Significant predictors for death were shorter time from symptom onset to admission, male sex, high viral load on initial laboratory testing, severe pain, diarrhea, bloody feces, and development of other bleeding manifestations during hospitalization. These risk factors for death could be used to identify patients in need of more intensive medical support. The lack of fever in as many as one third of EVD cases may have implications for temperature-screening practices and case definitions.

    Little is known about the social and political factors that influence priority setting for different health services in low- and middle-income countries (LMICs), yet these factors are integral to understanding how national health agendas are established. We investigated factors that facilitate or prevent surgical care from being prioritized in LMICs. We undertook country case studies in Papua New Guinea, Uganda, and Sierra Leone, using a qualitative process-tracing method. We conducted 74 semi-structured interviews with stakeholders involved in health agenda setting and surgical care in these countries. Interviews were triangulated with published academic literature, country reports, national health plans, and policies. Data were analyzed using a conceptual framework based on four components (actor power, ideas, political contexts, issue characteristics) to assess national factors influencing priority for surgery. Political priority for surgical care in the three countries varies. Priority was highest in Papua New Guinea, where surgical care is firmly embedded within national health plans and receives significant domestic and international resources, and much lower in Uganda and Sierra Leone. Factors influencing whether surgical care was prioritized were the degree of sustained and effective domestic advocacy by the local surgical community, the national political and economic environment in which health policy setting occurs, and the influence of international actors, particularly donors, on national agenda setting. The results from Papua New Guinea show that a strong surgical community can generate priority from the ground up, even where other factors are unfavorable. National health agenda setting is a complex social and political process. To embed surgical care within national health policy, sustained advocacy efforts, effective framing of the problem and solutions, and country-specific data are required.

    Full Text Available Abstract Lassa fever (LF is a devastating viral disease prevalent in West Africa. Efforts to take on this public health crisis have been hindered by lack of infrastructure and rapid field deployable diagnosis in areas where the disease is prevalent. Recent capacity building at the Kenema Government Hospital Lassa Fever Ward (KGH LFW in Sierra Leone has lead to a major turning point in the diagnosis, treatment and study of LF. Herein we present the first comprehensive rapid diagnosis and real time characterization of an acute hemorrhagic LF case at KGH LFW. This case report focuses on a third trimester pregnant Sierra Leonean woman from the historically non-endemic Northern district of Tonkolili who survived the illness despite fetal demise. Employed in this study were newly developed recombinant LASV Antigen Rapid Test cassettes and dipstick lateral flow immunoassays (LFI that enabled the diagnosis of LF within twenty minutes of sample collection. Deregulation of overall homeostasis, significant hepatic and renal system involvement, and immunity profiles were extensively characterized during the course of hospitalization. Rapid diagnosis, prompt treatment with a full course of intravenous (IV ribavirin, IV fluids management, and real time monitoring of clinical parameters resulted in a positive maternal outcome despite admission to the LFW seven days post onset of symptoms, fetal demise, and a natural still birth delivery. These studies solidify the growing rapid diagnostic, treatment, and surveillance capabilities at the KGH LF Laboratory, and the potential to significantly improve the current high mortality rate caused by LF. As a result of the growing capacity, we were also able to isolate Lassa virus (LASV RNA from the patient and perform Sanger sequencing where we found significant genetic divergence from commonly circulating Sierra Leonean strains, showing potential for the discovery of a newly emerged LASV strain with expanded geographic

    This study describes phenotypic, genotypic and antibiotic susceptibility patterns of the strains isolated from the 2012 Sierra Leone cholera outbreak. Rectal swabs were collected from patients and cultured for Vibrio cholerae O1. The isolates were subjected to multiplex PCR, mismatch amplification mutation assay (MAMA) PCR, pulsed field gel electrophoresis (PFGE), and antibiotic sensitivity tests using disk diffusion and minimum inhibitory concentration (MIC) E-test following standard procedures. Out of 17 rectal swabs tested, 15 yielded V. cholerae O1 biotype El Tor, serotype Ogawa. All the strains belonged to 'altered' variants as MAMA PCR result showed the presence of classical cholera toxin B. PFGE result revealed four pulse types. Using antibiotic disk diffusion, all the isolates were resistant to erythromycin, chloramphenicol, furazolidone, and trimethoprim/sulfamethoxazole (SXT) except SL1 which was sensitive to chloramphenicol and SXT. All the isolates were sensitive to nalidixic acid, tetracycline, doxycycline, azithromycin, and ciprofloxacin except SL2 which was resistant to nalidixic acid. However, variable sensitivity patterns were observed for kanamycin. The ranges of MIC were 0.125-0.50 mg/l, 0.003-0.023 mg/l and 0.38-0.75 mg/l for azithromycin, ciprofloxacin and tetracycline, respectively. This study demonstrates that altered variants of V. cholerae O1 of four clonal types were responsible for the 2012 outbreak of cholera in Sierra Leone. © The Author 2014.

    2015-09-01

    The need for evidence-based practice calls for research focussing not only on the effectiveness of interventions and their translation into policies, but also on implementation processes and the factors influencing them, in particular for complex health system policies. In this paper, we use the lens of one of the health system's 'building blocks', human resources for health (HRH), to examine the implementation of official policies on HRH incentives and the emergence of informal practices in three districts of Sierra Leone. Our mixed-methods research draws mostly from 18 key informant interviews at district level. Data are organised using a political economy framework which focuses on the dynamic interactions between structure (context, historical legacies, institutions) and agency (actors, agendas, power relations) to show how these elements affect the HRH incentive practices in each district. It appears that the official policies are re-shaped both by implementation challenges and by informal practices emerging at local level as the result of the district-level dynamics and negotiations between District Health Management Teams (DHMTs) and nongovernmental organisations (NGOs). Emerging informal practices take the form of selective supervision, salary supplementations and per diems paid to health workers, and aim to ensure a better fit between the actors' agendas and the incentive package. Importantly, the negotiations which shape such practices are characterised by a substantial asymmetry of power between DHMTs and NGOs. In conclusion, our findings reveal the influence of NGOs on the HRH incentive package and highlight the need to empower DHMTs to limit the discrepancy between policies defined at central level and practices in the districts, and to reduce inequalities in health worker remuneration across districts. For Sierra Leone, these findings are now more relevant than ever as new players enter the stage at district level, as part of the Ebola response and

    The purpose of this study was to assess the levels of polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethane (DDE), and four heavy metals (arsenic, cadmium, and lead) in outdoor surface soils (50 samples) collected from the metropolitan area of Monterrey in Mexico. Total PBDEs levels ranged from 1.80 to 127 µg/kg, with mean total PBDEs level of 14.2 ± 21.5 µg/kg (geometric mean ± standard deviation). For PCBs, the mean total level in the studied soils was 23.5 ± 20.2 µg/kg (range 4.0-65.5 µg/kg). An important finding in our study was that all soil samples (100%) had detectable levels of the metabolite p,p'-DDE. Moreover, the mean total DDT level (∑p'p-DDT and p'p-DDE) was approximately 132 ± 175 µg/kg. The mean levels for arsenic, cadmium, and lead in soil were 5.30 ± 1.35 (range 1.55-7.85) mg/kg, 2.20 ± 1.20 (range 0.65-6.40) mg/kg, and 455 ± 204 (range 224-1230) mg/kg, respectively. Our study has several limitations, the most notable of which is the small sample of soils evaluated. However, this screening study provided concentration data for the occurrence of POPs and four heavy metals in soil from the metropolitan area of Monterrey, Nuevo Leon, Mexico, and taking into consideration that soil is an important pathway of exposure for people, a biomonitoring program for the surveillance of the general population in the metropolitan area of Monterrey, Nuevo Leon is deemed necessary.

    Background Ebola virus emerged in West Africa in December 2013. The high population mobility and poor public health infrastructure in this region led to the development of the largest Ebola virus disease (EVD) outbreak to date. Methodology/Principal findings On September 26, 2014, China dispatched a Mobile Biosafety Level-3 Laboratory (MBSL-3 Lab) and a well-trained diagnostic team to Sierra Leone to assist in EVD diagnosis using quantitative real-time PCR, which allowed the diagnosis of suspected EVD cases in less than 4 hours from the time of sample receiving. This laboratory was composed of three container vehicles equipped with advanced ventilation system, communication system, electricity and gas supply system. We strictly applied multiple safety precautions to reduce exposure risks. Personnel, materials, water and air flow management were the key elements of the biosafety measures in the MBSL-3 Lab. Air samples were regularly collected from the MBSL-3 Lab, but no evidence of Ebola virus infectious aerosols was detected. Potentially contaminated objects were also tested by collecting swabs. On one occasion, a pipette tested positive for EVD. A total of 1,635 suspected EVD cases (824 positive [50.4%]) were tested from September 28 to November 11, 2014, and no member of the diagnostic team was infected with Ebola virus or other pathogens, including Lassa fever. The specimens tested included blood (69.2%) and oral swabs (30.8%) with positivity rates of 54.2% and 41.9%, respectively. The China mobile laboratory was thus instrumental in the EVD outbreak response by providing timely and reliable diagnostics. Conclusions/Significance The MBSL-3 Lab significantly contributed to establishing a suitable laboratory response capacity during the emergence of EVD in Sierra Leone. PMID:28505171

    The 2014 Ebola Virus Disease epidemic evolved in alarming ways in Sierra Leone spreading to all districts. The country struggled to control it against a backdrop of a health system that was already over-burdened. Health workers play an important role during epidemics but there is limited research on how they cope during health epidemics in fragile states. This paper explores the challenges faced by health workers and their coping strategies during the Ebola outbreak in four districts - Bonthe, Kenema, Koinadugu and Western Area - of Sierra Leone. We used a qualitative study design: key informant interviews (n = 19) with members of the District Health Management Teams and local councils, health facility managers and international partners; and in depth interviews with health workers (n = 25) working in public health facilities and international health workers involved with the treatment of Ebola patients. There were several important coping strategies including those that drew upon existing mechanisms: being sustained by religion, a sense of serving their country and community, and peer and family support. Externally derived strategies included: training which built health worker confidence in providing care; provision of equipment to do their job safely; a social media platform which helped health workers deal with challenges; workshops that provided ways to deal with the stigma associated with being a health worker; and the risk allowance, which motivated staff to work in facilities and provided an additional income source. Supportive supervision, peer support networks and better use of communication technology should be pursued, alongside a programme for rebuilding trusting relations with community structures. The challenge is building these mechanisms into routine systems, pre-empting shocks, rather than waiting to respond belatedly to crises.

    Freetown, the capital of Sierra Leone has experienced vast land-cover changes over the past three decades. In Sierra Leone, however, availability of updated land-cover data is still a problem even for environmental managers. This study was therefore, conducted to provide up-to-date land-cover data for Freetown. Multi-temporal Landsat data at 1986, 2001, and 2015 were obtained, and a maximum likelihood supervised classification was employed. Eight land-cover classes or categories were recognized as follows: water, wetland, built-up, dense forest, sparse forest, grassland, barren, and mangrove. Land-cover changes were mapped via post-classification change detection. The persistence, gain, and loss of each land-cover class, and selected land conversions were also quantified. An overall classification accuracy of 87.3 % and a Kappa statistic of 0.85 were obtained for the 2015 map. From 1986 to 2015, water, built-up, grassland, and barren had net gains, whereas forests, wetlands, and mangrove had net loses. Conversion analyses among forests, grassland, and built-up show that built-up had targeted grassland and avoided forests. This study also revealed that, the overall land-cover change at 2001-2015 was higher (28.5 %) than that recorded at 1986-2001 (20.9 %). This is attributable to the population increase in Freetown and the high economic growth and infrastructural development recorded countrywide after the civil war. In view of the rapid land-cover change and its associated environmental impacts, this study recommends the enactment of policies that would strike a balance between urbanization and environmental sustainability in Freetown.

    Packaged drinking water (PW) sold in bottles and plastic bags/sachets is widely consumed in low- and middle-income countries (LMICs), and many urban users in sub-Saharan Africa (SSA) rely on packaged sachet water (PSW) as their primary source of water for consumption. However, few rigorous studies have investigated PSW quality in SSA, and none have compared PSW to stored household water for consumption (HWC). A clearer understanding of PSW quality in the context of alternative sources is needed to inform policy and regulation. As elsewhere in SSA, PSW is widely consumed in Sierra Leone, but government oversight is nearly nonexistent. This study examined the microbiological and chemical quality of a representative sample of PSW products in Freetown, Sierra Leone at packaged water manufacturing facilities (PWMFs) and at points of sale (POSs). Samples of HWC were also analyzed for comparison. The study did not find evidence of serious chemical contamination among the parameters studied. However, 19% of 45 PSW products sampled at the PWMF contained detectable Escherichia coli (EC), although only two samples exceeded 10 CFU/100 mL. Concentrations of total coliforms (TC) in PSW (but not EC) increased along the supply chain. Samples of HWC from 60 households in Freetown were significantly more likely to contain EC and TC than PSW at the point of production (p<0.01), and had significantly higher concentrations of both bacterial indicators (p<0.01). These results highlight the need for additional PSW regulation and surveillance, while demonstrating the need to prioritize the safety of HWC. At present, PSW may be the least unsafe option for many households. PMID:26162082

    Although several medicinal plants has been documented to alleviate diabetes in Nuevo Leon, Northeast of Mexico, no systematic study has been undertaken to determine the efficacy of these plant species. The present study was undertaken to determine micronutrients (Cu, Fe and Zn) and macro-nutrients (K, Mg and P), C, N and C/N and to select plants with high macro and micronutrient contents for high efficacy in 18 medicinal plants collected from botanical gardens of Forest Science Faculty, UANL, Mexico used in Nuevo Leon in Northeast of Mexico, at the experimental station of Facultad de Ciencias Forestales, Universidad Autonoma de Nuevo Leon. Following standard protocols, carbon and nitrogen were determined using a CHN analyzer (Perkin Elmer, model 2400). Mineral contents were using the wet digestion technique (Cherney, 2000). The present study indicated the presence of large variation in the contents of several macro and micronutrients among these 18 species of medicinal plants utilized traditionally to control diabetes and other diseases in Nuevo Leon, Mexico. Among these species containing high nitrogen content (%) are Moringa oleifera (6.25), Melia azadirachta (5.85), Marrubium vulgare (4.56) and Phoradendron villosum (4.9). The C/N values ranged from 8 to 30. The species having high C/N were Agave macroculmis (30), Arbutus xalapensis (26) and Rhus virens (22). The species Melia azadirachta, Marrubium vulgare, Buddleja cordata, Tecoma stans, Hedeoma palmeri, Phoradendron villosum, Opuntia ficus-indica, Arbutus xalapensis exhibited large variations in the contents of macro and micronutrients which, could be considered to be used effectively for the control of diabetes. Few species viz. Marrubium vulgare, Buddleja cordata, Tecoma stans, Hedeoma palmeri, Phoradendron villosum, Opuntia ficus-indica and Arbutus xalapensis on the basis of high nutrient content with respect to C, N, C/N, Cu, Fe, Zn, K, P and Mg are selected and recommended to control diabetes.

    An epidemic of Ebola virus disease (EVD) beginning in 2013 has claimed an estimated 11 310 lives in West Africa. As the EVD epidemic subsides, it is important for all who participated in the emergency Ebola response to reflect on strengths and weaknesses of the response. Such reflections should take into account perspectives not usually included in peer-reviewed publications and after-action reports, including those from the public sector, nongovernmental organizations (NGOs), survivors of Ebola, and Ebola-affected households and communities. In this article, we first describe how the international NGO Partners In Health (PIH) partnered with the Government of Sierra Leone and Wellbody Alliance (a local NGO) to respond to the EVD epidemic in 4 of the country's most Ebola-affected districts. We then describe how, in the aftermath of the epidemic, PIH is partnering with the public sector to strengthen the health system and resume delivery of regular health services. PIH's experience in Sierra Leone is one of multiple partnerships with different stakeholders. It is also one of rapid deployment of expatriate clinicians and logistics personnel in health facilities largely deprived of health professionals, medical supplies, and physical infrastructure required to deliver health services effectively and safely.

    Full Text Available Most low-income nations have national medicine policy that emphasized the use of generic medicines in the public health sector. However, the use of generics is often debatable as there are concerns over its efficacy, quality, and safety compared to their branded counterparts. This study was conducted to compare the knowledge and perception of generic medicines among final year undergraduate medical, pharmacy, and nursing students in Sierra Leone. We conducted a questionnaire-based cross-sectional study among these students at the College of Medicine and Allied Health Sciences University of Sierra Leone. Out of the 62 students, only two (2/62, 3.2% knew about the acceptable bioequivalence limit. At least half of respondents in all three groups agreed that all generics are therapeutically equivalent to their innovator brand. At least half of the medicine (21/42, 50% and nursing (6/9, 66.6% students, compared to pharmacy students (5/11, 45.5%, believed that higher safety standards are required for proprietary medicines than for generic medicines. Most of them agreed that they need more information on the safety, quality, and efficacy aspects of generics (59/62, 95.2%. All three groups of healthcare students, despite variations in their responses, demonstrated a deficiency in knowledge and misconception regarding generic medicines. Training on issues surrounding generic drugs in healthcare training institutions is highly needed among future healthcare providers in Sierra Leone.

    The rising level of antimicrobial resistance among bacterial pathogens is one of the most significant public health problems globally. While the antibiotic resistance of clinically important bacteria is closely tracked in many developed countries, the types and levels of resistance and multidrug resistance (MDR) among pathogens currently circulating in most countries of sub-Saharan Africa are virtually unknown. From December 2013 to April 2014, we collected 93 urine specimens from all outpatients showing symptoms of urinary tract infection (UTI) and 189 fomite swabs from a small hospital in Bo, Sierra Leone. Culture on chromogenic agar combined with biochemical and DNA sequence-based assays was used to detect and identify the bacterial isolates. Their antimicrobial susceptibilities were determined using a panel of 11 antibiotics or antibiotic combinations. The 70 Enterobacteriaceae urine isolates were identified as Citrobacter freundii (n = 22), Klebsiella pneumoniae (n = 15), Enterobacter cloacae (n = 15), Escherichia coli (n = 13), Enterobacter sp./Leclercia sp. (n = 4) and Escherichia hermannii (n = 1). Antimicrobial susceptibility testing demonstrated that 85.7 % of these isolates were MDR while 64.3 % produced an extended-spectrum ß-lactamase (ESBL). The most notable observations included widespread resistance to sulphonamides (91.4 %), chloramphenicol (72.9 %), gentamycin (72.9 %), ampicillin with sulbactam (51.4 %) and ciprofloxacin (47.1 %) with C. freundii exhibiting the highest and E. coli the lowest prevalence of multidrug resistance. The environmental cultures resulted in only five Enterobacteriaceae isolates out of 189 collected with lower overall antibiotic resistance. The surprisingly high proportion of C. freundii found in urine of patients with suspected UTI supports earlier findings of the growing role of this pathogen in UTIs in low-resource countries. The isolates of all analyzed species showed worryingly high

    Edible wild mushroom picking is becoming an important source of income in rural areas. The wide range of activities which add value to mycological production (initial sale, transformation, marketing, etc.) include those related to tourism which can attract visitors to mushroom producing areas, leading to so-called mycological tourism. To date, no research exists quantifying the importance thereof in rural areas endowed with such resources. The present research provides the first model to estimate this activity contribution to the economy of rural areas in the region of Castilla y Leon. The main finding to emerge evidences a close link between influx of visitors, who come principally to pick, and mycological productivity in the region. Based on this relation, we estimate four key variables to determine the impact which said activity has on the regional economy as a whole: the number of overnight stays and trips made by mycological tourists, as well as associated expenditure and employment created. Findings underscore the importance of this activity in the regional tourism industry and point to its significance as a major market niche, particularly during the hotel low season. The need for public administrators to implement a related management policy is also inferred. (Author) 35 refs.

    Full Text Available Secondo numerosi osservatori, i combattimenti scoppiati dal 1989 al 2003 nei paesi dell’Africa occidentale della Mano River Union (Sierra Leone, Liberia e Guinea erano la dimostrazione che questa regione fosse estranea all’economia globale e rappresentavano una regressione verso una violenza tribale e primitiva. In realtà, la guerra lungo il fiume Mano è stata un conflitto post-moderno per eccellenza. La ricerca etnografica fra i combattenti, in entrambi i lati della frontiera, mostra che in questo campo di battaglia si era affermata una politica economica fondata sul lavoro violento, all’interno di un continuum che includeva l’estrazione dei diamanti e dell’oro nel profondo della foresta pluviale, la raccolta della gomma nelle piantagioni regionali e le campagne elettorali a favore dei politici nelle principali città della regione. Lungi dall’essere una regressione verso uno stato pre-moderno, le dinamiche dell’aggregazione e del dispiegamento della forza lavoro nel mestiere della guerra suggeriscono che questa regione era, ed è tuttora, un laboratorio per il capitalismo del futuro.

    Sierra Leone experienced intense transmission of Ebola virus disease (EVD) from May 2014 to November 2015 during which a total of 8,704 confirmed cases and over 3,589 confirmed deaths were reported. Our field observation showed many issues in the EVD data management system, which may have contributed to the magnitude and long duration of the outbreak. In this perspective article, we explain the key issues with EVD data management in the field, and the resulting obstacles in analyzing key epidemiological indicators during the outbreak response work. Our observation showed that, during the latter part of the EVD outbreak, surveillance and data management improved at all levels in the country as compared to the earlier stage. We identified incomplete filling and late arrival of the case investigation forms at data management centers, difficulties in detecting double entries and merging identified double entries in the database, and lack of clear process of how death of confirmed cases in holding, treatment, and community care centers are reported to the data centers as some of challenges to effective data management. Furthermore, there was no consolidated database that captured and linked all data sources in a structured way. We propose development of a new application tool easily adaptable to new occurrences, regular data harmonization meetings between national and district data management teams, and establishment of a data quality audit system to assure good quality data as ways to improve EVD data management during future outbreaks.

    ABSTRACT Optimal breastfeeding is of vital importance to infant and child health and has been adopted by countries as a standard recommendation. However, in the context of an infectious disease outbreak, especially when the disease is poorly understood, policy makers must balance the benefits of breastfeeding against the risk of disease transmission through breastfeeding. During the 2014–2015 Ebola Virus Disease (EVD) outbreak in Sierra Leone, the development of correct and consistent messaging about infant feeding and nutrition programming was considerably delayed by numerous challenges. These challenges included a lack of sufficient information about the risk of transmission through human milk, numerous stakeholders, limited communication between coordination pillars, inconsistent and evolving messages from various stakeholders, and the public's distrust of the health system and international actors. For improved response to future disease outbreaks, research on vertical transmission of EVD should be prioritized, infant and young child feeding experts should be integrated into outbreak response collaboration, and a digital repository of potential and appropriately tailored messages should be created.

    Full Text Available The controversies of microfinance are to a large extent fueled by its unclear definition and limited understanding of the extent of its impact. The problem of taxonomy leads to contrast between idealistic beliefs in the sectorial mission and pragmatic solutions of MFIs causing misinterpretations of the realities by financial laity as well as by development experts. Lack of comprehension of the potential as well as an ideal socio-economic habitat and target profile of microdebtors in the light of problems of over indebtedness belongs to such problems. An in-depth comprehension of the profile of a desirable microfinance client denominated as microcredit mannequin from the development perspective and a grasp of a combination of drivers that make microenterpreneurs in developing countries often contracting microdebt might serve as a tool for more efficient focus of microfinance in developing countries. An understanding of the meaning of microfinance and the characteristics of a desirable client could help focus on particular socio-economic strata prevention of overindebtedness and improve the impact of debt especially in rural areas where microfinance is most needed and where it lacks most expertise. The study was founded upon field data collected in regions in Sierra Leone from 800 microfinance debtors as well as non-microfinance practitioners and compares their socio-economic profiles in order to arrive to a set of generalised conclusions on the particular drivers that define microfinance clientele.

    Full Text Available Small and medium enterprises in the automotive industry in Mexico play an increasingly important role in the development of national industry, contributing to 2.6% of GDP and represent 11.5% of the manufacturing sector. However, in a recent study of TBM Consulting found that only 20% of auto parts manufacturers in Mexico have the potential to become world-class suppliers of the automotive industry, 40% are in the process of improvement and the remaining 40%, still doing things the traditional way. According to this analysis, including the difficulties faced by SMEs are unable to comply with the requirements of quality products, poor marketing, lack of refinancing, lack of efficient management techniques, among others. In this research is to analyze the problems of SMEs in the automotive sector in the State of Nuevo León and whether having a system implementation of 5S's is looking to integrate the methodologies needed to be innovative, strengthen intercompany and to adopt the ABC costing accounting system, allowing them to have a better quality and successful integration in the automotive supply chain in Nuevo Leon.

    In low and high income countries alike, disability exacerbates social, economic, and health disparities, in spite of their differences. This study seeks to identify factors that predict the circumstances people with disabilities face, including poverty. A cross-sectional study design was employed using census track level data for the cities of Monterrey, Nuevo Leon, and Dallas, Texas, from Mexico 2010 and USA 2000 census data collections. Two methods, spatial autocorrelation and geographically weighted regression were used to identify spatial patterns of disability and to explore the relation between disability and context-specific socio-demographic factors. Results indicated that people with disabilities living below the poverty line experience high segregation levels in the semi-central zones of Dallas. In Monterrey, people with disabilities clustered in central areas of the city. A Geographically Weighted Regression (GWR) from both data analyses reported high goodness of fit (R ≥ 0.8 for Dallas data and R ≥ 0.7 for Monterrey data, respectively) and predictability of disability prevalence when social disadvantage factors such as unemployment, housing insecurity, household living conditions, and lack of education were present. The divergent and sometimes conflicting trends in practices and policies addressing disability in low and high income environments renders a reexamination of the framework of disability. An understanding of local characteristics joins a grounded socio-cultural understanding of the various contexts that shape location-based social networks and political decisions in providing such an analysis.

    2013-01-01

    Rural water supply sustainability has remained an enduring policy challenge in sub-Saharan Africa for decades. Drawing on the largest data set assembled on rural water points in sub-Saharan Africa to date, this paper employs logistic regression analyses to identify operational, technical, institutional, financial, and environmental predictors of functionality for over 25 000 community-managed handpumps in Liberia, Sierra Leone, and Uganda. Risk factors significantly associated with nonfunctionality across all three countries were (a) system age, (b) distance from district/county capital, and (c) absence of user fee collection. In at least one of the three countries, other variables found to have significant multivariable adjusted associations with functionality status included well type, handpump type, funding organization, implementing organization, spare parts proximity, availability of a handpump mechanic, regular servicing, regular water committee meetings, women in key water committee positions, rainfall season, and perceived water quality. While the findings reinforce views that a multifaceted range of conditions is critical for the sustainability of community-managed handpumps, they also demonstrate that these factors remain absent from a high proportion of cases. Governments and development partners must significantly strengthen postconstruction support for operation and maintenance systems, and greater efforts are needed to test and evaluate alternative models for managing handpump water supplies.

  12. Football and post-war reintegration: exploring the role of sport in DDR processes in Sierra Leone.

    Growing enthusiasm for 'Sport for development and peace' (SDP) projects around the world has created a much greater interest among critical scholars seeking to interrogate potential gains, extant limitations and challenges of using sport to advance 'development' and 'peace' in Africa. Despite this interest, the role of sport in post-conflict peace building remains poorly understood. Since peace building, as a field of study, lends itself to practical approaches that seek to address underlying sources of violent conflict, it is surprising that it has neglected to take an interest in sport, especially its grassroots models. In Africa, football (soccer) in particular has a strong appeal because of its popularity and ability to mobilise individuals and communities. Through a case study on Sierra Leone, this paper focuses on sports in a particularly prominent post-civil war UN intervention—the disarmament, demobilisation and reintegration (DDR) process—to determine how ex-youth combatants, camp administrators and caregivers perceive the role and significance of sporting activities in interim care centres (ICCS) or DDR camps. It argues that sporting experiences in ddr processes are fruitful microcosms for understanding nuanced forms of violence and healing among youth combatants during their reintegration process.

    To investigate patients' preferences for patient-centered communication (PCC) in the encounter with healthcare professionals in an outpatient department in rural Sierra Leone. A survey was conducted using an adapted version of the Patient-Practitioner Orientation Scale (PPOS) as a structured interview guide. The study population was drawn from the population of all adults attending for treatment or treatment for their children. 144 patients were included in the analysis. Factors, such as doctor's friendly approach, the interpersonal relationship and information-sharing were all scored high (patient-centered) on the PPOS. Factors associated with shared-decision making had a lower (doctor-centered) score. A high educational level was associated with a more patient-centered scoring, an association that was most pronounced in the female population. The results provide an insight into the patients' preferences for PCC. Patients expressed a patient-centered attitude toward certain areas of PCC, while other areas were less expressed. More research is needed in order to fully qualify the applicability of PCC in resource-poor settings. Stakeholders and healthcare professionals should aim to strengthen healthcare practice by focusing on PCC in the medical encounter while taking into considerations the patients' awareness and preferences for PCC.

    Image guide radiotherapy with the Cone Beam CT kV (C.B.C.T.-kV) developed by Elekta has been implemented at the centre Leon Berard in November 2006. The treatment procedure is presented and detailed for prostate cancer I.G.R.T. and non small cell lung cancer (N.S.C.L.C.) stereotactic radiotherapy (S.R.T.). C.B.C.T.-kV is routinely used for S.R.T., selected paediatric cancers, all prostate carcinomas, primitive brain tumours and head and neck cancers that do not require nodes irradiation. Thirty-five to 40 patients are treated within a daily 11-hours period. The general procedure for 3-dimensional images acquisition and their analysis is described. The C.B.C.T.-kV permitted to identify about 10% of prostate cancer patients for whom a positioning with bone-based 2-dimensional images only would have led to an unacceptable dose distribution for at least one session. S.R.T. is now used routinely for inoperable N.S.C.L.C.. The easiness of implementing C.B.C.T.-kV imaging and its expected medical benefit should lead to a rapid diffusion of this technology that is also submitted to prospective and multi centric medico-economical evaluations.

    Full Text Available Ebola virus (EBOV can lead to severe hemorrhagic fever with a high risk of death in humans and other primates. To guide treatment and prevent spread of the viral infection, a rapid and sensitive detection method is required for clinical samples. Here, we described and evaluated a reverse transcription loop-mediated isothermal amplification (RT-LAMP method to detect Zaire ebolavirus using the nucleoprotein gene (NP as a target sequence. Two different techniques were used, a calcein/Mn2+ complex chromogenic method and real-time turbidity monitoring. The RT-LAMP assay detected the NP target sequence with a limit of 4.56 copies/μL within 45 min under 61°C, a similar even or increase in sensitivity than that of real-time reverse transcription-polymerase chain reaction (RT-PCR. Additionally, all pseudoviral particles or non- Zaire EBOV genomes were negative for LAMP detection, indicating that the assay was highly specific for EBOV. To appraise the availability of the RT-LAMP method for use in clinical diagnosis of EBOV, of 417 blood or swab samples collected from patients with clinically suspected infections in Sierra Leone, 307 were identified for RT-LAMP-based surveillance of EBOV. Therefore, the highly specific and sensitive RT-LAMP method allows the rapid detection of EBOV, and is a suitable tool for clinical screening, diagnosis, and primary quarantine purposes.

    The link between economic empowerment and high risky sexual behaviour has been debated by different scholars in various settings. However, no consistently clear connection between poverty and lack of education has been found regarding engagement in risky sexual behaviour. Also, not much research has been done to examine the strength of these relationships for adolescents and women. The objectives of this study were to assess the relationship between female economic empowerment and risky sexual behaviour in Africa. Using the latest Demographic and Health Surveys Data (DHS 2011-2014) from Gabon, Mozambique, Sierra Leone and Zambia, univariate, bivariate and multivariate analysis was done on women aged 15 to 49 to examine the patterns of and differences in the association between women's economic empowerment and risky sexual behaviour. The findings both at community and individual level indicate that empowered women (higher education and wealth household) and adolescents aged 15 to 19 are highly significantly associated with engagement in high risky behaviour. The result of this study stresses the need to look further than individual factors in the quest to resolve risky sexual behaviour in Africa. The interrelations between female economic empowerment and engagement in risky sexual behaviour are more complicated and less straightforward than usually presumed.

    Human immunodeficiency virus type 2 (HIV-2) originated from simian immunodeficiency viruses (SIVs) that naturally infect sooty mangabeys (SMs; Cercocebus atys). In order to further investigate the relationship between HIV-2 and SIVsm, the SIV specific to the SM, we characterized seven new SIVsm strains from SMs sold in Sierra Leone markets as bush meat. The gag, pol, and env sequences showed that, while the viruses of all seven SMs belonged to the SIVsm-HIV-2 lineage, they were highly divergent viruses, in spite of the fact that most of the samples originated from the same geographical region. They clustered in three lineages, two of which have been previously reported. Two of the new SIVsm strains clustered differently in gag and env phylogenetic trees, suggesting SIVsm recombination that had occurred in the past. In spite of the fact that our study doubles the number of known SIVsm strains from wild SMs, none of the simian strains were close to the groups in which HIV-2 was epidemic (groups A and B).

    The dynamics of sperm DNA fragmentation (sDF) and sperm viability were analyzed in frozen-thawed sperm samples of Equus asinus (Zamorano-Leonés), a breed at risk of extinction. Sperm DNA fragmentation was assessed using an adaptation of the sperm chromatin dispersion test developed for stallions in five different frozen samples. Sperm were thawed and incubated at different temperatures (37 degrees C, 25 degrees C, and 4 degrees C) and sDF was assessed at different times and compared. The mean sDF after thawing at the beginning of the experiment was 18.20+/-14.77% and did not differ significantly from the results of a neutral comet assay (22.0+/-19.34%). The tendency in the sDF of all donkeys indicated that sperm DNA is more sensitive to breakage when incubated at 37 degrees C than when incubated at 25 degrees C or 4 degrees C. Interestingly, the tendency was not the same when different animals were compared, and differences in sDF dynamics were established among individuals. sDF correlated negatively with sperm viability in some individuals but not in others. From a conservation perspective, sDF analysis may offer a new way to assess sperm quality in endangered breeds in order to identify and select the best semen samples for artificial reproduction purposes. In particular, we recommend for artificial insemination the use of semen samples with a slow increase in sDF with time after thawing.

    Full Text Available Future infectious disease epidemics are likely to disproportionately affect countries with weak health systems, exacerbating global vulnerability. To decrease the severity of epidemics in these settings, lessons can be drawn from the Ebola outbreak in West Africa. There is a dearth of literature on public perceptions of the public health response system that required citizens to report and treat Ebola cases. Epidemiological reports suggested that there were delays in diagnosis and treatment. The purpose of our study was to explore the barriers preventing Sierra Leoneans from trusting and using the Ebola response system during the height of the outbreak.Using an experienced ethnographer, we conducted 30 semi-structured in-depth interviews in public spaces in Ebola-affected areas. Participants were at least age 18, spoke Krio, and reported no contact in the recent 21 days with an Ebola-infected person. We used inductive coding and noted emergent themes.Most participants feared that calling the national hotline for someone they believed had Ebola would result in that person's death. Many stated that if they developed a fever they would assume it was not Ebola and self-medicate. Some thought the chlorine sprayed by ambulance workers was toxic. Although most knew there was a laboratory test for Ebola, some erroneously assumed the ubiquitous thermometers were the test and most did not understand the need to re-test in the presence of Ebola symptoms.Fears and misperceptions, related to lack of trust in the response system, may have delayed care-seeking during the Ebola outbreak in Sierra Leone. Protocols for future outbreak responses should incorporate dynamic, qualitative research to understand and address people's perceptions. Strategies that enhance trust in the response system, such as community mobilization, may be particularly effective.

    Setting: Twenty-seven peripheral health units, five secondary hospitals and one tertiary hospital, Western Area District, Sierra Leone. Objectives: To describe reporting systems, monthly attendances and facility-based patterns of six non-communicable diseases (NCDs) in the pre-Ebola and Ebola virus disease outbreak periods. Design: A cross-sectional study using programme data. Results: Reporting was 89% complete on the six selected NCDs pre-Ebola and 86% during the Ebola outbreak ( P < 0.01). Overall, marked declining trends in NCDs were reported during the Ebola period, with a monthly mean of 342 cases pre-Ebola and 164 during the Ebola outbreak. The monthly mean number of cases per disease in the pre-Ebola and Ebola outbreak periods was respectively 228 vs. 85 for hypertension, 43 vs. 27 for cardiovascular diseases, 36 vs. 18 for diabetes and 25 vs. 29 for peptic ulcer disease; this last condition increased during the outbreak. There were higher proportions of NCDs among females during the Ebola outbreak compared with the pre-Ebola period. Except for peptic ulcer disease, the number of patients with NCDs declined by 25% in peripheral health units, 91% in the secondary hospitals and 70% in the tertiary hospital between the pre-Ebola and the Ebola outbreak periods. Conclusion: Comprehensive reporting of NCDs was suboptimal, and declined during the Ebola epidemic. There were decreases in reported attendances for NCDs between the pre-Ebola and the Ebola outbreak periods, which were even more marked in the hospitals. This study has important policy implications.

    Full Text Available he discovery of a valuable and important sphragistic source in Cherson – the seal of Strategos and Patrikios Leon Aliates, known by the inscription of 1059, brings us back to the old problems of the development of the administrative system of the Crimean region. Basing the research on the other data as well, today we can confidently state that the presence of the imperial administration in Taurica in the second half of the 11th century does not only decrease, but even expands and reinforces. This is associated, firstly, with Sougdea joining Cherson, and, secondly, with the creation of Cherson katepanate and making Sougdea an independent theme. The seal of vetarch Nicephorus Alan, catepan of Cherson and Khazaria, proves the existence of a new military administrative district in Taurica in the second half of the 11th – at the turn of the 11th / 12th centuries. This fact makes it necessary not only to look in a new way at the history of the region during the collapse of the feudal system, but also in a certain sense to reestimate the role and significance of Cherson in Byzantine politics and diplomacy of that time. The appearance of the katepanate in Taurica, which included not only the traditional regions around Cherson, but also the vast Khazar lands of the Steppe and Northeast Crimea in the sphere of its jurisdiction, was caused by the need to increase the military force of borderlands in the face of an ever-increasing threat from the nomads of the north. For the same reason, Sougdea becomes an independent theme, designed to control the East-Crimean region, the Azov Sea and the Caucasian coast of Ponta. It is possible that a similar situation could apply to Bosporus. The finds of the seals of Russian princes and governors of Tmutarakan in the very area of Bosporus and Sougdea serve as indirect evidence in favor of this fact.

    In the largest Ebola virus disease (EVD) outbreak in history, nosocomial transmission of EVD increased spread of the disease. We report on 2 instances in Sierra Leone where patients unknowingly infected with EVD were admitted to a general hospital ward (1 pediatric ward and 1 maternity ward), exposing health care workers, caregivers, and other patients to EVD. Both patients died on the general wards, and were later confirmed as being infected with EVD. We initiated contact tracing and assessed risk factors for secondary infections to guide containment recommendations. We reviewed medical records to establish the index patients' symptom onset. Health care workers, patients, and caregivers were interviewed to determine exposures and personal protective equipment (PPE) use. Contacts were monitored daily for EVD symptoms. Those who experienced EVD symptoms were isolated and tested. Eighty-two contacts were identified: 64 health care workers, 7 caregivers, 4 patients, 4 newborns, and 3 children of patients. Seven contacts became symptomatic and tested positive for EVD: 2 health care workers (1 nurse and 1 hospital cleaner), 2 caregivers, 2 newborns, and 1 patient. The infected nurse placed an intravenous catheter in the pediatric index patient with only short gloves PPE and the hospital cleaner cleaned the operating room of the maternity ward index patient wearing short gloves PPE. The maternity ward index patient's caregiver and newborn were exposed to her body fluids. The infected patient and her newborn shared the ward and latrine with the maternity ward index patient. Hospital staff members did not use adequate PPE. Caregivers were not offered PPE. Delayed recognition of EVD and inadequate PPE likely led to exposures and secondary infections. Earlier recognition of EVD and adequate PPE might have reduced direct contact with body fluids. Limiting nonhealth-care worker contact, improving access to PPE, and enhancing screening methods for pregnant women, children

    2017-01-01

    With Sustainable Development Goal 7, the United Nations has declared its ambition to ensure access to modern energy for all by 2030. Aside from broad appeals to differentiated responsibilities and 'greener' technologies, however, the goal leaves significant procedural questions unaddressed. This paper argues that the basic orientation of this approach is problematic, undermining possibilities for progress toward energy justice and equitable development. First, in framing the issue of global energy distribution in broad techno-managerial terms it obscures how particular geographies of energy poverty have been shaped by critical political economic influences. Second, in privileging modern forms of energy and focusing on an end state of universal adoption, over a broader goal of eliminating energy poverty, the approach of SDG7 presents tangible hazards to many of those it seeks to benefit. Using a case study of Sierra Leonean rural cooking energy policy, we demonstrate how the underlying mentality of SDG7 feeds into existing discourses that marginalise producers and users of 'traditional' energy sources, threatening important livelihoods. With such evidence, we argue that for justice in energy policy to be realised holistically, there is a need to question how our knowledge of energy ‘problems’ have emerged to avoid epistemologically autarchic policy positions. - Highlights: • Examination of the justice issues within the text of Sustainable Development Goal 7. • Investigates how fuelwood is entangled with energy justice issues in Sierra Leone. • Argues energy solutions need to shift away from simple technological fixes. • Energy policy needs to be built on a range of energy knowledges and experiences.

    BACKGROUND The current outbreak of Ebola virus disease (EVD) in West Africa has attacked 24000 people, killed more than 10000 and disrupted social life. METHODS We studied retrospectively the clinical presentation and risk factors for fatal outcome in EVD among all patients admitted to the Ebola Treatment Center in Moyamba District, Sierra Leone. RESULTS Among a total of 88 admitted patients, eighty-two were tested by PCR and 31 (38%) were positive for Ebola virus. Ninety percent reported previous contact with EVD patients and 35% had participated in burials of EVD suspect deceased. No healthworkers were admitted. The most common symptoms on admission were weakness (97%), diarrhea (68%), fever (62%), loss of appetite (62%), vomiting (58%), pain in muscles (62%) and joints (55%), headache (55%), abdominal pain (45%) and conjunctivitis (42%). On admission, bleeding was present in one-third (11/31), while more than half (17/31) bled during the hospital stay. Fifty-eight percent (18/31) died, most within 4-11 days of onset. Significant predictors for fatal outcome were shorter time from onset to admission (P=0.02), high initial viral load (P<0.001), bleeding (P=0.004), and severe pain (P=0.001). The only two patients with hiccups died. CONCLUSIONS Bleeding was more common in our cohort than reported elsewhere during this epidemic, and predicted poor prognosis. Severe pain was common, particularly in fatal cases, and calls for improved and safe palliation, for instance with transdermal opiates. The lack of fever in one third of EBV cases may have implications for screening procedures and case definitions.

    The Ebola virus disease (EVD) crisis in West Africa began in March 2014. At the beginning of the outbreak, no one could have predicted just how far-reaching its effects would be. The EVD epidemic proved to be a unique and unusual humanitarian and public health crisis. It caused worldwide fear that impeded the rapid response required to contain it early. The situation in Sierra Leone (SL) forced the formation of a unique series of civil-military interagency relationships to be formed in order to halt the epidemic. Civil-military cooperation in humanitarian situations is not unique to this crisis; however, the slow response, the unusual nature of the battle itself and the uncertainty of the framework required to fight this deadly virus created a situation that forced civilian and military organisations to form distinct, cooperative relationships. The unique nature of the Ebola virus necessitated a steering away from normal civil-military relationships and standard pillar responses. National and international non-governmental organisations (NGOs), Department for International Development (DFID) and the SL and UK militaries were required to disable this deadly virus (as of 7 November 2015, SL was declared EVD free). This paper draws on personal experiences and preliminary distillation of information gathered in formal interviews. It discusses some of the interesting features of the interagency relationships, particularly between the military, the UK's DFID, international organisations, NGOs and departments of the SL government. The focus is on how these relationships were key to achieving a coordinated solution to EVD in SL both on the ground and within the larger organisational structure. It also discusses how these relationships needed to rapidly evolve and change along with the epidemiological curve. Published by the BMJ Publishing Group Limited.

  7. Impacts on the Urban Environment: Land Cover Change Trajectories and Landscape Fragmentation in Post-War Western Area, Sierra Leone

    Directory of Open Access Journals (Sweden)

    Solomon Peter Gbanie

    2018-01-01

    Full Text Available An influential underlying driver of human-induced landscape change is civil war and other forms of conflict that cause human displacement. Internally displaced persons (IDPs increase environmental pressures at their destination locations while reducing them at their origins. This increased pressure presents an environment for increased land cover change (LCC rates and landscape fragmentation. To test whether this hypothesis is correct, this research sought to understand LCC dynamics in the Western Area of Sierra Leone from 1976 to 2011, a period including pre-conflict, conflict, and post-conflict eras, using Landsat and SPOT satellite imagery. A trajectory analysis of classified images compared LCC trajectories before and during the war (1976–2000 with after the war (2003–2011. Over the 35-year period, the built-up land class rapidly increased, in parallel with an increase in urban and peri-urban agriculture. During the war, urban and peri-urban agriculture became a major livelihood activity for displaced rural residents to make the region food self-sufficient, especially when the war destabilised food production activities. The reluctance of IDPs to return to their rural homes after the war caused an increased demand for land driven by housing needs. Meanwhile, protected forest and other forest declined. A significant finding to emerge from this research is that landscape fragmentation increased in conjunction with declining forest cover while built-up areas aggregated. This has important implications for the region’s flora, fauna, and human populations given that other research has shown that landscape fragmentation affects the landscape’s ability to provide important ecosystem services.

     During 2014-2015, an outbreak of Ebola virus disease (EVD) swept across parts of West Africa. No approved antiviral drugs are available for Ebola treatment currently.  A retrospective clinical case series was performed for EVD patients in Sierra Leone-China Friendship Hospital. Patients with confirmed EVD were sequentially enrolled and treated with either World Health Organization (WHO)-recommended supportive therapy (control group) from 10 to 30 October, or treated with WHO-recommended therapy plus favipiravir (T-705) from 1 to 10 November 2014. Survival and virological characteristics were observed for 85 patients in the control group and 39 in the T-705 treatment group.  The overall survival rate in the T-705 treatment group was higher than that of the control group (56.4% [22/39] vs 35.3% [30/85]; P = .027). Among the 35 patients who finished all designed endpoint observations, the survival rate in the T-705 treatment group (64.8% [11/17]) was higher than that of the control group (27.8% [5/18]). Furthermore, the average survival time of the treatment group (46.9 ± 5.6 days) was longer than that of the control group (28.9 ± 4.7 days). Most symptoms of patients in the treatment group improved significantly. Additionally, 52.9% of patients who received T-705 had a >100-fold viral load reduction, compared with only 16.7% of patients in the control group.  Treatment of EVD with T-705 was associated with prolonged survival and markedly reduced viral load, which makes a compelling case for further randomized controlled trials of T-705 for treating EVD. © The Author 2016.

  9. Analysis of the Nuevo Leon magnetic anomaly and its possible relation to the Cerro Prieto magmatic-hydrothermal system

    The broad dipolar magnetic anomaly whose positive peak is centered near Ejido Nuevo Leon, some 5 km east of the Cerro Prieto I Power Plant, has long been suspected to have a genetic relationship to the thermal source of the Cerro Prieto geothermal system. This suspicion was reinforced after several deep geothermal wells, drilled to depths of 3 to 3.5 km over the anomaly, intersected an apparent dike-sill complex consisting mainly of diabase but with minor rhyodacite. A detailed fit of the observed magnetic field to a computer model indicates that the source may be approximated by a tabular block 4 by 6 km in area, 3.7 km in depth, 2.3 km thick, and dipping slightly to the north. Mafic dike chips from one well, NL-1, were analyzed by means of electron microprobe analyses which showed tham to contain a titanomagnetite that is paramagnetic at in-situ temperature conditions. As the dike mineralogy does not account for the magnetic anomaly, the magnetic source is believed to be a deeper, magnetite-rich assemblage of peridotite-gabbro plutons. the suite of igneous rocks was probably passively emplaced at a shallow depth in response to crustal extension and thinning brought on by strike-slip faulting. The bottom of the magnetic source body, at an estimated depth of 6 km, is presumed to be at or near that of the Curie isotherm (575/sup 0/C) for magnetite, the principal ferromagnetic mineral in peridotitic-gabbroic rocks. The geological model derived from the magnetic study is generally supported by other geophysical data. In particular, earthquake data suggest dike injection is occurring at depths of 6 to 11 km in an area beneath the magnetic source. Thus, it is possible that heat for the geothermal field is being maintained by continuing crustal extension and magmatic activity.

    Globally, diarrhea remains a leading killer of young children. In Sierra Leone, one in seven children die before their fifth birthday and diarrhea is a leading cause. Studies that emphasize the demand-side of health interventions -- how caregivers understand causation and prevention of diarrhea -- have been neglected in research and programming. We undertook applied qualitative research including 68 in-depth interviews and 36 focus group discussions with mothers, fathers and older female caretakers to examine the causes and prevention of childhood diarrhea in villages near and far from health facilities across four rural districts. Verbal consent was obtained. Respondents reported multiple, co-existing descriptions of causation including: contaminated water and difficulties accessing clean water; exposure to an unclean environment and poor food hygiene; contaminated breast milk due to sexual intercourse, overheated breast milk or bodily maternal conditions such as menstruation or pregnancy; and dietary imbalances and curses. Respondents rarely discussed the role of open defecation or the importance of handwashing with soap in preventing diarrhea. Categorizing behaviors as beneficial, harmful, non-existent or benign enables tailored programmatic recommendations. For example, respondents recognized the value of clean water and we correspondingly recommend interventions that reinforce consumption of and access to clean water. Second, respondents report denying "contaminated" breast milk to breastfeeding children. This is a harmful practice that merits attention. Third, the role of open defecation and poor hygiene in causing diarrhea is less understood and warrants introduction or clarification. Finally, the role of exposed feet or curses in causing diarrhea is relatively benign and does not necessitate programmatic attention. Further research supportive of communication and social mobilization strategies building on these findings is required to ensure that improved

    2016-11-01

    Full Text Available Background: Response to the 2014–2015 Ebola Virus Disease (EVD outbreak in Sierra Leone overwhelmed the national capacity to contain it and necessitated a massive international response and strong coordination platform. Consequently, the Sierra Leone Government, with support of the international humanitarian community, established and implemented various models for national coordination of the outbreak. In this article we review the strengths and limitations of the EVD outbreak response coordination systems in Sierra Leone and propose recommendations for improving coordination of similar outbreaks in the future. Conclusions: There were two main frameworks used for the coordination of the outbreak; the Emergency Operation Center (EOC and the National Ebola Response Center (NERC. We observed an improvement in outbreak coordination as the management mechanism evolved from the EOC to the NERC. Both coordination systems had their advantages and disadvantages; however the NERC coordination mechanism appeared to be more robust. We identified challenges, such as competition and duplication of efforts between the numerous coordination groups, slow resource mobilization, inadequate capacity of NERC/EOC staff for health coordination and an overtly centralized coordination and decision making system as the main coordination challenges during the outbreak. Recommendations: We recommend the establishment of emergency operation centers with simple incident management system-based coordination prior to outbreaks, strong government leadership, decentralization of coordination systems and functions to the epicenter of outbreaks, with clear demarcation of roles and responsibilities between different levels, regular training of key coordination leaders and better community participation as methods to improve coordination of future disease outbreaks.

The methodology followed in the landscape evaluation tries to integrate all the aspects that can be taken into consideration when an evaluation of this kind is undertaken (philosophical, psychological and territorial approach. Thus a complete evaluation method, applicable on Spanish landscapes, is verified and validated. The estimation of the landscape impact of the constructions is conducted by estimating the adaptation of the constructions to the environment, taking as a basis a previously elaborated typology of the constructions. The combination of the values of adaptation to the environment of each construction and the evaluation of the landscape in which the construction is situated gives the impact value. The work carried out leads to interesting conclusions related to both values of the landscape itself and the constructions in the Páramo Leonés, as well as to the methodologies followed in the evaluations.

    Vaccinating healthcare professionals against influenza is considered an effective infection control measure. However, there is a low uptake of influenza vaccine among healthcare professionals around the globe. Currently, it is unknown whether healthcare professionals in Sierra Leone are aware of, and have been vaccinated against influenza. Also, there is a paucity of research evidence on their level of knowledge and attitude toward influenza vaccination. This study assessed healthcare professionals' current influenza vaccine uptake rate, reasons for not getting vaccinated as well as their awareness, knowledge of, and attitude towards influenza vaccination in Freetown Sierra Leone. A cross-sectional study was conducted between February and April 2016 among healthcare providers working in four public and two private health facilities in Freetown Sierra Leone. Linear regression analysis, one-way ANOVA and independent t-test were employed for data analysis. Among 706 respondents that participated in the study more than half were females 378 (53.6%), nurses 425 (60.4%), and the majority were between the age group of 20-39 years 600 (85.3%). Only 46 (6.5%) were vaccinated against influenza. Key reasons for not vaccinated against influenza were less awareness about influenza vaccination among HCPs 580 (82.73%) with (β = 0.154; CI 0.058-0.163), the high cost of influenza vaccines and therefore not normally purchased 392 (55.92%) having (β = 0.150; CI 0.063-0.186). More than half believed that HCPs are less susceptible to influenza infections than other people. Also, majority 585 (84.3%) of HCPs thought that influenza disease could be transmitted after symptoms appear. In addition, 579 (83.2%) of HCPs felt that symptoms usually appear 8-10 days after exposure. Close to half 321 (46.0%) of HCPs were not aware of the influenza immunisation guidelines published by the Advisory Committee on Immunization Practices and Centre for Disease Control.

    A survey for ozone-induced foliar injury of black cherry was conducted in mid-June 1995 within the Desierto de Los Leones National Park located southwest of Mexico City. Evaluations of the upper and lower tree crowns of 18 trees revealed evidence of significant upper surface stipple, leaf reddening and premature senescence on 72% of the trees. A general survey of an additional 169 trees disclosed that 41% exhibited similar symptoms. A gradient of increasing symptoms with increasing elevation was also evident. For the most part, asymptomatic trees were observed to be situated within well-shaded coves at the lower elevations with very few symptomatic trees present in these areas.

  17. Il particolare italiano da Guicciardini a Banfield. Tra l’autoriconoscimento e l’etero-riconoscimento

    2011-11-01

    Full Text Available Nel 1958 la pubblicazione dell’indagine di Edward Banfield The Moral Basis of a Backward Society, suscitò un fervente dibattito nella comunità dei sociologi italiani e stranieri — la disputa sull’amoral familism, il concetto esplicativo centrale, è ancora aperta. Considerare primigenia l’interpretazione dello studioso statunitense è tuttavia un errore. Ampliando lo sguardo analitico si rintracciano spiegazioni analoghe e di gran lunga antecedenti dell’arretratezza sociale, economica e politica italiana: il “paese del tornaconto personale” di Leon Battista Alberti; il particulare di Guicciardini. L’idea di una mancanza strutturale (culturale? di senso civico da parte degli italiani affonda nei secoli e appartiene innanzitutto al momento dell’auto-riconoscimento identitario. Solo in un secondo tempo, con le note di viaggio del Grand Tour, questa rappresentazione entra a far parte dell’etero-riconoscimento nordeuropeo e molti anni dopo nordamericano. Quando un tratto identitario ottiene un “doppio riconoscimento” di così lunga durata, diviene un tòpos, un punto cardinale delle rappresentazioni individuali e collettive di un popolo. Chi sostiene tesi contrarie a Banfield si deve misurare con un altro ostacolo: la forza retorica dell’espressione “familismo amorale”. Tentare di costruire nuove e altrettanto efficaci locuzioni sintetiche, ovviamente frutto di buone interpretazioni teoriche, pare l’imprescindibile via ermeneutica da imboccare. A tal fine è necessario “dar battaglia” sullo stesso campo di indagine: un questionario difficilmente scalzerà i dispositivi narrativi costruiti attraverso le osservazioni etnografiche di un ricercatore che va sul campo — e che ci rimane per un anno. Se è chiaro che si può far meglio di Banfield, è pure chiaro che bisogna provarci. Esiste un’ulteriore barriera per chi intenda proporre diverse letture del processo di modernizzazione italiana: il peso della realt

    A central pillar in the response to the 2014 Ebola virus disease (EVD) epidemic in Sierra Leone was the role of Ebola Holding Units (EHUs). These units isolated patients meeting a suspect case definition, tested them for EVD, initiated appropriate early treatment and discharged negative patients to onward inpatient care or home. Positive patients were referred to Ebola Treatment Centres. We aimed to estimate the risk of nosocomial transmission within these EHUs. We followed up a cohort of 543 patients discharged with a negative EVD test from five EHUs in the Western Area, Sierra Leone, and examined all line-listed subsequent EVD tests from any facility in the Western Area to see whether the patient was retested within 30 days, matching by name, age and address. We defined possible readmissions as having the same name and age but uncertain address, and confirmed readmissions where name, age and address matched. We found a positive readmission rate of 3.3% (18 cases), which included 1.5% confirmed readmissions (8 cases) and 1.8% possible readmissions (10 cases). This is lower than rates previously reported. We cannot ascertain whether EVD was acquired within the EHUs or from re-exposure in the community. No demographic or clinical variables were identified as risk factors for positive readmission, likely due to our small sample size. These findings support the EHU model as a safe method for isolation of suspect EVD patients and their role in limiting the spread of EVD. © 2016 John Wiley & Sons Ltd.

    Nongovernmental organizations (NGOs) play a critical humanitarian role in the developing world. Over 100 NGOs currently operate in Sierra Leone, a country in West Africa that ranks 183 out of 187 in the United Nation's Human Development Index. Following a brutal 11-year war that ended in January 2002, the country has been unsuccessful at building a sufficiently resourced, robust, and anticipatory public health and medical care infrastructure. Consequently, Sierra Leone suffers from high levels of poverty, infant mortality, and limited access to safe drinking water, as well as morbidity from malnutrition, diarrheal diseases, hepatitis A, cholera, and typhoid fever. Large international NGOs such as Doctors Without Borders have attempted to fill the void left by fragile and fragmented government health services but have been overwhelmed and saturated by the continual spread of Ebola virus disease and growing numbers of cases and deaths. Smaller NGOs endeavored to assist during this crisis as well. One of them, Caritas, has actively sought public health knowledge and has applied public health principles to reduce and contain Ebola virus disease transmission. The Ebola outbreak illuminates the importance of building basic public health capabilities within the core competences of NGOs.

    The influence of dental correction on nociceptive (pressure) test responses, fecal appearance, BCS, and apparent digestibility coefficient for DM was studied in 18 Zamorano-Leonés donkeys, an endangered local breed from the Zamora province in Spain. For this purpose, donkeys were divided into 2 homogeneous control and treatment groups, based on age, BCS, and dental findings. On d 1, 45, 90, and 135, BCS and nociceptive test responses were evaluated in all donkeys. Feed and fecal samples were collected from all donkeys for 3 consecutive days, starting at each of the aforementioned days. Apparent digestibility coefficient for DM was estimated, using ADL as an internal marker. A progressive decrease of positive nociceptive test responses was observed from d 1 up to 90 (P < 0.01) in the treatment group. No difference between groups was observed for BCS. However, BCS at d 90 was greater (P = 0.018) than observed on d 1 or 45, indicating a time influence. Concerning apparent digestibility coefficient for DM, there were differences among collection days in apparent digestibility coefficient for DM (P < 0.05). No differences in fecal appearance were observed between treatments or collection days. This study highlighted the importance of regular dental care for not only Zamorano-Leonés donkeys but also the equid population, in general, to improve their welfare.

    Full Text Available Students in present-day Greek schools are taught History as a biography of the Greek nation from the Mycenaean times to the present. Over the course of three millennia, the Greek nation has experienced three periods of cultural flourishing and political autonomy: (i the period of Antiquity (from the times of legendary King Agamemnon to those of Alexander the Great, (ii the Byzantine period (from Justinian’s ascension in the 6th century to the Fall of Constantinople in 1453, and (iii the modern era (from the War of Independence in 1821 to the present day. However, in this article we argue that in the 19th century the history taught in Greek schools differed substantially from the tripartite schema described above. In support of our thesis, we examine the most popular school textbook of the 19th century, O Gerostathis, by Leon Melas. In the Gerostathis, the history of the Greek nation is identified with that of Classical Greece (i.e. from the 6th century BC to the 4th century BC, which is held up as an exemplary era worthy of emulation. In contrast, the rise of Macedon under Philip II signals the cultural decline of the Greeks and the loss of their political autonomy, which was not regained for two millennia, until the 1821 national revolution. In that period, the Greek nation ceased not to exist, but survived as a subjugate of the Macedonians, the Romans, and finally the Ottomans. The Byzantine, on the other hand, is described as an unremarkable period of decadence that is only worth mentioning in relation to its final period, that of the Palaeologus dynasty, which bestowed upon the Greeks a legacy of resistance against the Ottomans. We argue that the above reading of the Greek past owed much to the Enlightenment, which as an intellectual movement still exerted a powerful influence (albeit to a gradually diminishing degree on Greek intellectuals up to the latter third of the 19th century.

    Sierra Leone experienced an unprecedented Ebola virus disease (EVD) outbreak in all its districts. Koinadugu District was the last to report an EVD case. Several outbreak response strategies were implemented. As part of lessons learnt, we conducted an observational study to describe the transmission chain in the district and the impact of the control measures implemented to contain the outbreak. We reconstructed the transmission chain, positioning both confirmed and probable cases, described the distribution of the EVD confirmed cases in the context of the routes of transmission (Community, Funeral or Health facility setting) and assessed the impact of control measures using the surveillance data collected during the outbreak. All 142 confirmed and probable EVD cases registered were fully resolved in the transmission chain. 72.5% of all the EVD cases in the district were exposed in the community, 26.1% exposed during funerals, and 1.4% exposed in the health facility setting. Health-care workers contributed little to the EVD outbreak. 71.1% of EVD transmission occurred among family members. Female EVD cases generated more secondary cases than their male counterparts ( P  = 0.03). With removal of EVD cases from the community and admission to the community care center (CCC), the EVD transmission in the community decreased to substantially lower rates. In addition, transmission due to exposure in health facilities was further reduced with the implementation of full infection and prevention controls. This study details the transmission chain of EVD in a rural district setting and the public health interventions implemented to successfully limit the outbreak to just one of 11 chiefdoms. Heightened community-based surveillance for early case detection, swift isolation of suspect cases, efficient contact tracing and monitoring, and good infection prevention and control measures in health facilities were highly effective in limiting transmission and, eventually

    The size of the west African Ebola virus disease outbreak led to the urgent establishment of Ebola holding unit facilities for isolation and diagnostic testing of patients with suspected Ebola virus disease. Following the onset of the outbreak in Sierra Leone, patients presenting to Connaught Hospital in Freetown were screened for suspected Ebola virus disease on arrival and, if necessary, were admitted to the on-site Ebola holding unit. Since demand for beds in this unit greatly exceeded capacity, we aimed to improve the selection of patients with suspected Ebola virus disease for admission by identifying presenting clinical characteristics that were predictive of a confirmed diagnosis. In this retrospective cohort study, we recorded the presenting clinical characteristics of suspected Ebola virus disease cases admitted to Connaught Hospital's Ebola holding unit. Patients were subsequently classified as confirmed Ebola virus disease cases or non-cases according to the result of Ebola virus reverse-transcriptase PCR (EBOV RT-PCR) testing. The sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio of every clinical characteristic were calculated, to estimate the diagnostic accuracy and predictive value of each clinical characteristic for confirmed Ebola virus disease. Between May 29, 2014, and Dec 8, 2014, 850 patients with suspected Ebola virus disease were admitted to the holding unit, of whom 724 had an EBOV RT-PCR result recorded and were included in the analysis. In 464 (64%) of these patients, a diagnosis of Ebola virus disease was confirmed. Fever or history of fever (n=599, 83%), intense fatigue or weakness (n=495, 68%), vomiting or nausea (n=365, 50%), and diarrhoea (n=294, 41%) were the most common presenting symptoms in suspected cases. Presentation with intense fatigue, confusion, conjunctivitis, hiccups, diarrhea, or vomiting was associated with increased likelihood of confirmed Ebola virus disease. Three or

    In survivors of Ebola virus disease, clinical sequelae including uveitis, arthralgia, and fatigue are common and necessitate systematic follow-up. However, the infection risk to health-care providers is poorly defined. Here we report Ebola virus RT-PCR data for body site and fluid samples from a large cohort of Ebola virus survivors at clinic follow-up. In this cross-sectional cohort study, consecutive survivors of Ebola virus disease attending Kerry Town survivor clinic (Freetown, Sierra Leone), who had been discharged from the Kerry Town Ebola treatment unit, were invited to participate. We collected and tested axillary, blood, conjunctival, forehead, mouth, rectal, semen, urine, and vaginal specimens for presence of Ebola virus using RT-PCR. We regarded samples to be positive for Ebola virus disease if the cycle threshold was 40 or lower. We collected demographic data from survivors of their age, sex, time since discharge from the treatment unit, and length of acute admission in the Ebola treatment unit using anonymised standard forms. Between April 2, and June 16, 2015, of 151 survivors of Ebola virus disease invited to participate, 112 (74%) provided consent. The median age of participants was 21·5 years (IQR 14-31·5) with 34 (30%) participants younger than 16 years. 50 (45%) of 112 participants were male. We tested a total of 555 specimens: 103 from the axilla, 93 from blood, 92 from conjunctiva, 54 from forehead, 105 from mouth, 17 from the rectum, one from semen, 69 from urine, and 21 from the vagina. The median time from Ebola treatment unit discharge to specimen collection was 142 days (IQR 127-159). 15 participants had a total of 74 swabs taken less than 100 days from discharge. The semen sample from one participant tested positive for Ebola virus at 114 days after discharge from the treatment unit; specimens taken from the axilla, blood, conjunctiva, forehead, mouth, rectum, and urine of the same participant tested negative.

    Background Sierra Leone has among the poorest maternal and child health indicators in the world and investments in public health have been predominately to increase demand for services, with fewer initiatives targeting supply side factors that influence health workers’ work environment. This paper uses data from the Quality Circles project in a rural district of Sierra Leone to achieve three objectives. First, we examine the effect of the intervention on organizational skills and relationships among coworkers as well as between health workers and traditional birth attendants. Second, we examine whether changes in organizational skills are associated with changes in relationships among and between formal and informal health providers and between health providers and clients. Third, we aim to further understand these changes through the perspectives of health workers and traditional birth attendants. Methods The Quality Circles project was implemented in Kailahun District in the Eastern province of Sierra Leone from August 2011 to June 2013, with adjacent Tonkolili District serving as the control site. Using a mixed-methods approach, the evaluation included a quantitative survey, in-depth interviews and focus group discussions with health workers and traditional birth attendants. Mean values of the variables of interest were compared across sub-populations, and correlation analyses were performed between changes in organizational skills and changes in relationships. Results The results demonstrate that the Quality Circles intervention had positive effects on organizational skills and relationships. Furthermore, improvements in all organizational skill variables – problem-solving, strategizing and negotiation skills – were strongly associated with a change in the overall relationship variable. Conclusions The Quality Circles approach has the potential to support health workers to improve their organizational skills and relationships, which in turn can contribute

    The 2013–2016 outbreak of Ebola virus disease (EVD) in West Africa infected >28,000 people, including >11,000 who died, and disrupted social life in the region. We retrospectively studied clinical signs and symptoms and risk factors for fatal outcome among 31 Ebola virus–positive patients admitted to the Ebola Treatment Center in Moyamba District, Sierra Leone. We found a higher rate of bleeding manifestations than reported elsewhere during the outbreak. Significant predictors for death were shorter time from symptom onset to admission, male sex, high viral load on initial laboratory testing, severe pain, diarrhea, bloody feces, and development of other bleeding manifestations during hospitalization. These risk factors for death could be used to identify patients in need of more intensive medical support. The lack of fever in as many as one third of EVD cases may have implications for temperature-screening practices and case definitions. PMID:27268303

    Full Text Available The validity of the isoglosses by which the boundaries of the Leonese dialect in the province of Zamora have been traditionally indicated, especially as a way of identifying the area where this dialect was spoken in the early 20th century, has always been held in doubt. It is uncertain that the authors of the isoglosses kept in mind the systematic character of the studied phenomena for establishing the boundaries of this dialect. In all likelihood, the isoglosses represent the area where the phenomena were more frequently lexicalized rather than the area where they were actually spoken. Here the author attempts to set the eartern and western boundaries of the dialect in the province of Zamora by considering the lexicalized or systematic character of the phenomena. In addition, he identifies the different areas and subareas within those boundaries and, thereafter, compares his results with the representation received from Leonese dialectology. Relevant materials from the province of Zamora for this comparison are those included in the Linguistic Atlas of the Iberian Peninsula (ALPI, gathered in 1934 and 1935 by Aurelio M. Espinosa Jr. and Anibal Otero; more specifically, the materials of Cuaderno 1, published by David Heap in www.alpi.ca..

    The current outbreak of Ebola virus disease (EVD) in West Africa has infected more than 28,000 people, killed more than 11,000 and disrupted social life. We studied retrospectively the clinical presentation and risk factors for fatal outcome among the 31 Ebola virus (EBV) positive patients admitted to the Ebola Treatment Center (ETC) in Moyamba District, Sierra Leone. We found a higher rate of bleeding manifestations than reported elsewhere during the current outbreak. Significant predictors for fatal outcome were shorter time from onset to admission, male sex, high viral load on initial lab test, severe pain, diarrhea, bloody stools, and development of other bleeding manifestations during hospital admission. Awareness of risk factors for fatal outcome could be used to identify patients in need of more intensive medical support. The lack of fever in as much as a third of EVD cases may have implications for temperature screening practices and case definitions.

    Remnant tree presence affects forest recovery after slash-and-burn agriculture. However, little is known about its effect on above-ground carbon stocks, especially in Africa. We focused our study on Sierra Leone, part of the Upper Guinean forests, an important centre of endemism threatened...... by encroachment and forest degradation. We studied 99 (20-m-radius) plots aged 2-10 years with and without remnant trees and compared their above-ground carbon stocks, vegetation structure (stem density, basal area) and tree diversity. Above-ground carbon stocks, stem density, basal area, species richness...... and tree diversity increased significantly with fallow age. Remnant tree presence affected significantly tree diversity, species dominance and above-ground carbon stocks, but not vegetation structure (stem density, basal area). Number of remnant trees and number of species of remnant trees were also...

  16. Housing equity for health equity: a rights-based approach to the control of Lassa fever in post-war Sierra Leone

    2013-01-01

    Full Text Available Abstract Poor quality housing is an infringement on the rights of all humans to a standard of living adequate for health. Among the many vulnerabilities of those without adequate shelter is the risk of disease spread by rodents and other pests. One such disease is Lassa fever, an acute and sometimes severe viral hemorrhagic illness endemic in West Africa. Lassa virus is maintained in the rodent Mastomys natalensis, commonly known as the “multimammate rat,” which frequently invades the domestic environment, putting humans at risk of Lassa fever. The highest reported incidence of Lassa fever in the world is consistently in the Kenema District of Sierra Leone, a region that was at the center of Sierra Leone’s civil war in which tens of thousands of lives were lost and hundreds of thousands of dwellings destroyed. Despite the end of the war in 2002, most of Kenema’s population still lives in inadequate housing that puts them at risk of rodent invasion and Lassa fever. Furthermore, despite years of health education and village hygiene campaigns, the incidence of Lassa fever in Kenema District appears to be increasing. We focus on Lassa fever as a matter of human rights, proposing a strategy to improve housing quality, and discuss how housing equity has the potential to improve health equity and ultimately economic productivity in Sierra Leone. The manuscript is designed to spur discussion and action towards provision of housing and prevention of disease in one of the world’s most vulnerable populations.

    Dental disease is now recognised as a major but often unrecognised disorder of equids, including horses and donkeys. However, very few large clinical studies have documented the prevalence and type of dental disease present in different equid populations and no dental studies have been reported in Zamorano-Leonés or Mirandês donkeys, two endangered donkey breeds. Clinical and detailed oral examinations were performed in 400 Mirandês and 400 Zamorano-Leonés donkeys in Portugal and Spain. It was found that just 4.5 per cent had ever received any previous dental care. Cheek teeth (CT) disorders were present in 82.8 per cent of these donkeys, ranging from a prevalence of 29.6 per cent in the 25-year-old group. These CT disorders included enamel overgrowths (73.1 per cent prevalence but with just 6.3 per cent having associated soft tissue injuries), focal overgrowths (37.3 per cent), periodontal disease (23.5 per cent) and diastemata (19.9 per cent). Peripheral caries was present in 5.9 per cent of cases, but inexplicably, infundibular caries was very rare (1.3 per cent prevalence); this may have been due to their almost fully foraged diet. The high prevalence of enamel overgrowths in these donkeys, most which never received concentrates, also raises questions about the aetiology of this disorder. This very high prevalence of CT disorders, especially in older donkeys, was of great welfare concern in some cases and emphasises the need for routine dental care in these cases on welfare grounds and in order to help preserve these unique breeds.

    Full Text Available Abstract Background Since March 2014, the Ebola Virus Disease (EVD outbreak in West Africa disrupted health care systems - especially in Guinea, Liberia and Sierra Leone – with a consequential stress on the area’s routine immunization programs. To address perceived decreased vaccination coverage, Sierra Leone conducted a catch-up vaccination campaign during 24–27 April 2015. We conducted a vaccination coverage survey and report coverage estimates surrounding the time of the EVD outbreak and the catch-up campaign. Methods We selected 3 villages from each of 3 communities and obtained dates of birth and dates of vaccination with measles vaccine (MV and the 3rd dose of Pentavalent vaccine (Pentavalent3 of all children under 4 years of age in the 9 selected villages. Vaccination data were obtained from parent-held health cards. We calculated the children’s MV and Pentavalent3 coverage rates at 3 time points, 1 August 2014, 1 April 2015, and 1 May 2015, representing coverage rates before the EVD outbreak, during the EVD outbreak, and after the Maternal and Child Health Week (MCHW catch-up campaign. Results The final sample size was 168 children. MV coverage among age-eligible children was 71.3% (95% confidence interval [CI]: 62.1% - 80.4% and 45.7% (95% CI: 29.2% - 62.2% before and during the outbreak of EVD, respectively, and was 56.8% (95% CI: 40.8% - 72.7% after the campaign. Pentavalent3 coverage among age-eligible children was 79.8% (95% CI: 72.6% - 87.0% and 40.0% (95% CI: 22.5% - 57.5% before and during the outbreak of EVD, and was 56.4% (95% CI: 39.1% - 73.4% after the campaign. Conclusions Coverage levels of MV and Pentavalent3 were low before the EVD outbreak and decreased further during the outbreak. Although the MCHW catch-up campaign increased coverage levels, coverage remained below pre-outbreak levels. High-quality supplementary immunization activities should be conducted and routine immunization should be strengthened to

    Anecdotal evidence suggests that much of the continuing infection of health care workers (HCWs) with Ebola virus during the current outbreak in Sierra Leone has occurred in settings other than Ebola isolation units, and it is likely that some proportion of acquisition by HCWs occurs outside the workplace. There is a critical need to define more precisely the pathways of Ebola infection among HCWs, to optimise measures for reducing risk during current and future outbreaks. We conducted a retrospective descriptive study of Ebola acquisition among health workers in Sierra Leone during May-December 2014. The data used were obtained mainly from the national Ebola database, a cross-sectional survey conducted through administration of a structured questionnaire to infected HCWs, and key informant interviews of select health stakeholders. A total of 293 HCWs comprising 277 (95 %) confirmed, 6 (2 %) probable, and 10 (3 %) suspected cases of infection with Ebola virus were enrolled in the study from nine districts of the country. Over half of infected HCWs (153) were nurses; others included laboratory staff (19, 6.5 %), doctors (9, 3.1 %), cleaners and porters (9, 3.1 %), Community Health Officers (8, 2.7 %), and pharmacists (2, 0.7 %). HCW infections were mainly reported from the Western Area (24.9 %), Kailahun (18.4 %), Kenema (17.7 %), and Bombali (13.3 %) districts. Almost half of the infected HCWs (120, 47.4 %) believed that their exposure occurred in a hospital setting. Others believed that they were exposed in the home (48, 19 %), at health centres (45, 17.8 %), or at other types of health facilities (13, 5.1 %). Only 27 (10.7 %) of all HCW infections were associated with Ebola virus disease (EVD) isolation units. Over half (60 %, 150) of infected HCWs said they had been trained in infection prevention and control prior to their infection, whereas 34 % (85) reported that they had not been so trained. This study demonstrated the perception that most HCW infections are

    During the 2014-16 Ebola virus disease (EVD) outbreak, the Magburaka Ebola Management Centre (EMC) operated by Médecins Sans Frontières (MSF) in Tonkolili District, Sierra Leone, identified that available district maps lacked up-to-date village information to facilitate timely implementation of EVD control strategies. In January 2015, we undertook a survey in chiefdoms within the MSF EMC catchment area to collect mapping and village data. We explore the feasibility and cost to mobilise a local community for this survey, describe validation against existing mapping sources and use of the data to prioritise areas for interventions, and lessons learned. We recruited local people with self-owned Android smartphones installed with open-source survey software (OpenDataKit (ODK)) and open-source navigation software (OpenStreetMap Automated Navigation Directions (OsmAnd)). Surveyors were paired with local motorbike drivers to travel to eligible villages. The collected mapping data were validated by checking for duplication and comparing the village names against a pre-existing village name and location list using a geographic distance and text string-matching algorithm. The survey teams gained sufficient familiarity with the ODK and OsmAnd software within 1-2 hours. Nine chiefdoms in Tonkolili District and three in Bombali District were surveyed within two weeks. Following de-duplication, the surveyors collected data from 891 villages with an estimated 127,021 households. The overall survey cost was €3,395; €3.80 per village surveyed. The MSF GIS team (MSF-OCG) created improved maps for the MSF Magburaka EMC team which were used to support surveillance, investigation of suspect EVD cases, hygiene-kit distribution and EVD survivor support. We shared the mapping data with OpenStreetMap, the local Ministry of Health and Sanitation and Sierra Leone District and National Ebola Response Centres. Involving local community and using accessible technology allowed rapid

    Health workers are critical to the performance of health systems; yet, evidence about their coping strategies and support needs during and post crisis is lacking. There is very limited discussion about how research teams should respond when unexpected crises occur during on-going research. This paper critically presents the approaches and findings of two health systems research projects that explored and evaluated health worker performance and were adapted during crises, and provides lessons learnt on re-orientating research when the unexpected occurs. Health systems research was adapted post crisis to assess health workers' experiences and coping strategies. Qualitative in-depth interviews were conducted with 14 health workers in a heavily affected earthquake district in Nepal and 25 frontline health workers in four districts in Ebola-affected Sierra Leone. All data were transcribed and analysed using the framework approach, which included developing coding frameworks for each study, applying the frameworks, developing charts and describing the themes. A second layer of analysis included analysis across the two contexts, whereas a third layer involved the research teams reflecting on the approaches used to adapt the research during these crises and what was learned as individuals and research teams. In Sierra Leone, health workers were heavily stigmatised by the epidemic, leading to a breakdown of trust. Coping strategies included finding renewed purpose in continuing to serve their community, peer and family support (in some cases), and religion. In Nepal, individual determination, a sense of responsibility to the community and professional duty compelled staff to stay or return to their workplace. The research teams had trusting relationships with policy-makers and practitioners, which brought credibility and legitimacy to the change of research direction as well as the relationships to maximise the opportunity for findings to inform practice. In both contexts

A releitura de uma canção da Bossa Nova através de um filme que pretendia acompanhar o cotidiano de uma menina de classe média em Ipanema é esperada como um rompimento com os pressupostos do cinema político seguidos até então por seu diretor, um dos expoentes do Cinema Novo brasileiro. Afinal, tanto a Bossa quanto Ipanema eram consideradas metonímias de uma boêmia despolitizada que não se conectava, aparentemente, com a proposta de intervenção da arte na sociedade, seguida pelos cinemanovistas. Ironicamente, o filme decepcionou a crítica, justamente por não ser um bom entretenimento, se propondo a compreender a inserção da protagonista no mundo, inclusive sua relação com a política sob uma ditadura. Desse modo, a análise possibilita pensar as conexões entre ditadura, arte e boêmia no filme e através dele

    The head louse Pediculus humanus capitis (De Geer) is a hematophagous ectoparasite that inhabits the human scalp. Infestations by this insect are commonly known as pediculosis, which is more common in younger groups. These infestations are asymptomatic; however, skin irritation from scratching occasionally may cause secondary bacterial infections. In recent years, the prevalence of pediculosis has increased in children; this increase has been attributed to louse resistance to the insecticides used as a control measure for infestation. The aim of the present study was to determine the presence and frequency of the knockdown resistance mutation (kdr) T929I in 468 head lice collected from 32 elementary schools in the metropolitan area of Nuevo Leon (24) and Yucatan (8), Mexico. This is the first report of a knockdown resistance (kdr) mechanism in head lice from Mexico. The T929I mutation was present in all of the sampled schools, with variability observed in its allelic and genotypic frequencies. © The Authors 2017.

    This paper explores the possibilities for agency in intimate partner violence (IPV) situations from the perspective of women in Sierra Leone and Liberia using focus group discussions (N groups = 14, N participants = 110) and individual interviews (N = 20). Findings identify multiple interrelated factors influencing the decision-making of women experiencing IPV. At the individual level, emotional factors and women's knowledge of their rights and options influence their decision-making. At the relational level, the role of neighbours, family and friends is crucial, both for emotional support and practical assistance. At the community level, more formal structures play a role, such as chiefs and women's groups, though their effectiveness varies. At the structural level are barriers to effective responses, including a poorly functioning criminal justice system and a social system in which children often stay with fathers following separation or divorce. Strong cultural beliefs operate to keep women in abusive relationships. We identify implications for prevention and response services and make practice recommendations. Since the desire of most women experiencing IPV was to live in peace with their husbands, interventions should respect women's priorities by focusing more on prevention and interventions to end the violence, rather than solely assisting women to leave violent relationships.

    Full Text Available Protected area designation aims to protect forests from illegal activities such as hunting. However, the effectiveness of protection and how this changes over time in response to protection measures is difficult to assess, including the design of monitoring programmes able to detect changes. We present new data on rule-breaking prevalence in Gola Rainforest National Park, Sierra Leone, and use these data in spatially explicit simulations to assess the survey effort and design required to detect change and assess the effect of rule-breaker behaviour to these designs. Despite being a protected area, rule-breaking (in the form of signs of hunting occurred in almost 70% of 1 km survey squares but repeating this baseline survey of 53 survey squares would be insufficient to detect change. A much larger survey effort of 200-400 survey squares would be required to detect a 25% change in rule-breaking. Simulations highlight the extent to which rule-breaker behaviour, particularly hunter range size, influenced the likelihood of detecting change and importance of understanding this for survey design. A dedicated monitoring programme able to detect changes in the level of rule-breaking required an unrealistic level of resources, and we recommend combining monitoring with ranger patrol activities to reduce overall costs and employing questionnaire-based methods.

    Full Text Available Soil above a platinum-group element (PGE-bearing horizon within the Freetown Layered Intrusion, Sierra Leone, contains anomalous concentrations of n-alkanes (CnH2n+2 in the range C14 to C22 not readily attributable to an algal or lacustrine origin. Longer chain n-alkanes (C23 to C31 in the soil were derived from the breakdown of leaf litter beneath the closed canopy humid tropical forest. Spontaneous breakdown of the longer chain n-alkanes to form C14–22 n-alkanes without biogenic or abiogenic catalysts is unlikely as the n-alkanes are stable. In the Freetown soil, the catalytic properties of the PGE (Pt in particular may lower the temperature at which oxidation of the longer chain n-alkanes can occur. Reaction between these n-alkanes and Pt species, such as Pt2+(H2O2(OH2 and Pt4+(H2O2(OH4 can bend and twist the alkanes, and significantly lower the Heat of Formation. Microbial catalysis is a possibility. Since a direct organic geochemical source of the lighter n-alkanes has not yet been identified, this paper explores the theoretical potential for abiogenic Pt species catalysis as a mechanism of breakdown of the longer n-alkanes to form C14–22 alkanes. This novel mechanism could offer additional evidence for the presence of the PGE in solution, as predicted by soil geochemistry.

    The rare and deadly Ebola virus disease (EVD) is caused by Ebola virus (EBOV) infection. The 2014-2015 EVD outbreak in West Africa was unprecedented. Person-to-person transmission of EBOV by direct contact with the body or bodily fluids of an infected person through broken skin or unprotected mucous membrane caused rapid outbreak in communities. Nosocomial infection was the cause of death of many health care workers (HCWs). This paper aims to reveal the importance and effect of intensive education of HCWs when combating an outbreak such as EVD. We compared the curricula of two educational programs and analyzed their effects by the trend of weekly new patients. In September 2014, a three-day training program on infection, prevention and control (IPC) was organized for nurses, but it was not sufficient to achieve good outcome. In December 2014, a newly established National Ebola Training Academy was set up to offer a platform of clinical training modules for frontline Ebola response workers. This academy addressed the training needs of clinicians and hygienists who were working or will work at Ebola treatment centers that were established after the onset of the 2014 outbreak. Increased intensive contents and simulated training at the academy improved HCWs' understanding of EVD, IPC and patient care, which subsequently contributed to the survival of patients. The rapid settlement of the outbreak after introducing the Academy indicates that appropriate intensive education of HCWs is the key activity carried out to control the outbreak of EVD in Sierra Leone.

    Full Text Available Entre 1931 y 1932, como ocurrió en otras regiones españolas, Castilla y León asistió al resurgir de un regionalismo que hasta la fecha apenas había dado síntomas de vitalidad. A partir de esta realidad la pregunta que surge es si la renovada actividad regionalista castellano y leonesa reflejaba la actualización de un sentir originario y bien arraigado o era una respuesta obligada por el avance que estaba logrando el catalanismo durante el período considerado y por el nuevo modelo de organización territorial del Estado que definió la nueva Constitución de 1931. A la vista del comportamiento y manifestaciones de las fuerzas políticas, sociales e institucionales castellano y leonesas, podemos concluir que el regionalismo castellano y leonés no respondió a un sentimiento genuino y propio sino que fue la consecuencia de la necesidad de asumir un mal menor, de la adaptación a un nuevo modelo territorial no deseado.

    The UK deployed a task force to Sierra Leone to assist in ending the 2014/15 Ebola outbreak. Malaria protection was based on existing Defence Policy which saw a wide range of bite prevention measures deployed. Atovaquone/Proguanil ("A/P"), Doxycycline ("D") and Mefloquine ("M") were the chemoprophylactic medications that were prescribed. A survey was undertaken to audit the Adverse Effect (AE) burden experienced by the population. A questionnaire based survey was administered that sought information on individuals' experiences with malaria chemoprophylaxis. 337 personnel were eligible to take part and 151 (46.3%) individuals returned questionnaires. The reported AE rates for the three drugs were "A/P" 28% of the respondents, "D" 25% and "M" 23.1%. 24 individuals (15.9%) reported 1 AE while 34 (22.5%) reported multiple AEs. Eight (5.3%) individuals changed medication (Five "A/P", two "M" and one "D") because of unacceptable AE but no significant neuro/psychological conditions were reported. The malaria attack rate for the deployed population was 0.4 cases per thousand person weeks which is very low when compared to other military deployments to the West African Area. UK Defence policy is effective in the way it balances the risk of malaria with that of AE due to chemoprophylaxis. "M" remains an acceptable chemoprophylactic agent for a section of the population.

    As part of the UK response to the 2013-2016 Ebola virus disease (EVD) epidemic in West Africa, Public Health England (PHE) were tasked with establishing three field Ebola virus (EBOV) diagnostic laboratories in Sierra Leone by the UK Department for International Development (DFID). These provided diagnostic support to the Ebola Treatment Centre (ETC) facilities located in Kerry Town, Makeni and Port Loko. The Novel and Dangerous Pathogens (NADP) Training group at PHE, Porton Down, designed and implemented a pre-deployment Ebola diagnostic laboratory training programme for UK volunteer scientists being deployed to the PHE EVD laboratories. Here, we describe the training, workflow and capabilities of these field laboratories for use in response to disease epidemics and in epidemiological surveillance. We discuss the training outcomes, the laboratory outputs, lessons learned and the legacy value of the support provided. We hope this information will assist in the recruitment and training of staff for future responses and in the design and implementation of rapid deployment diagnostic field laboratories for future outbreaks of high consequence pathogens.This article is part of the themed issue 'The 2013-2016 West African Ebola epidemic: data, decision-making and disease control'. © 2017 The Author(s).

    Phylogeography improves our understanding of spatial epidemiology. However, application to practical problems requires choices among computational tools to balance statistical rigor, computational complexity, sensitivity to sampling strategy and interpretability. We introduce a fast, heuristic algorithm to reconstruct partially-observed transmission networks (POTN) that combines features of phylogenetic and transmission tree approaches. We compare the transmission network generated by POTN with existing algorithms (BEAST and SeqTrack), and discuss the benefits and challenges of phylogeographic analysis on examples of epidemic and endemic diseases: Ebola virus, H1N1 pandemic influenza and polio. For the 2014 Sierra Leone Ebola virus outbreak and the 2009 H1N1 outbreak, all three methods provide similarly plausible transmission histories but differ in detail. For polio in northern Nigeria, we discuss performance trade-offs between the POTN and discrete phylogeography in BEAST and conclude that spatial history reconstruction is limited by under-sampling. POTN is complementary to available tools on densely-sampled data, fails gracefully on under-sampled data and is scalable to accommodate larger datasets. We provide further evidence for the utility of phylogeography for understanding transmission networks of rapidly evolving epidemics. We propose simple heuristic criteria to identify how sampling rates and disease dynamics interact to determine fundamental limitations of phylogeographic inference. © The Author 2015.

    It is difficult for sites affected by mining to be colonized by vegetation and thus they suffer a slow recovery to a healthy ecosystem and, as a result, restoration work is necessary. The aim of this report is to propose a set of native species which are conducive to establishing a stable and self-sufficient plant community that will protect the soil and contribute to the rapid integration into the landscape of the areas affected by mining in the upper basin of the river Rodrigatos in the region of El Bierzo (Leon) An analysis of plant communities was undertaken using the phyto sociological method of Braun-Blanquet in order to subsequently select, using ecological criteria, the most suitable species for revegetation. Plant mapping using ortho photos was also developed in order to identify and delineate the location of the different landscape units. Among candidate species, in the first revegetation phase, we suggest a variety of herbs that are able to fix soils and protect them from erosion; species of the genus Cytisus and Genista in areas of moderate slope and species such as Rumex induratus Boiss and Reuter, Erysimum linifolium (Pourr. Ex Pers .) Jay in steeper areas because of their rooting ability. In later stages, the introduction of tree species characteristic for each formation is recommended. Furthermore, in the riverside areas species such as Carex elata subsp.reuteriana (Boiss.) Lucen and Aedo, Alnus glutinosa (L.) and Salix atrocinerea Brot. are proposed for introduction from the fi rst stage onwards. The species proposed in this study include some not commonly used in restoration, so a subsequent more detailed study would be required in order to assess their degree of suitability for this use.

    Background. The clinical and virologic characteristics of Ebola virus disease (EVD) in children have not been thoroughly documented. Methods. Consecutive children aged <18 years with real-time polymerase chain reaction (RT-PCR)–confirmed EVD were enrolled retrospectively in 5 Ebola treatment units in Liberia and Sierra Leone in 2014/2015. Data collection and medical management were based on standardized International Medical Corps protocols. We performed descriptive statistics, multivariate logistic regression, and Kaplan-Meier survival analyses. Results. Of 122 children enrolled, the median age was 7 years and one-third were aged <5 years. The female-to-male ratio was 1.3. The most common clinical features at triage and during hospitalization were fever, weakness, anorexia, and diarrhea, although 21% of patients were initially afebrile and 6 patients remained afebrile. Bleeding was rare at presentation (5%) and manifested subsequently in fewer than 50%. The overall case fatality rate was 57%. Factors associated with death in bivariate analyses were age <5 years, bleeding at any time during hospitalization, and high viral load. After adjustment with logistic regression modeling, the odds of death were 14.8-fold higher if patients were aged <5 years, 5-fold higher if the patient had any evidence of bleeding, and 5.2-fold higher if EVD RT-PCR cycle threshold value was ≤20. Plasmodium parasitemia had no impact on EVD outcomes. Conclusions. Age <5 years, bleeding, and high viral loads were poor prognostic indicators of children with EVD. Research to understand mechanisms of these risk factors and the impact of dehydration and electrolyte imbalance will improve health outcomes. PMID:28011610

    The 2013-2016 West African Ebola virus disease epidemic was unprecedented in terms of the number of cases and survivors. Prior to this epidemic there was limited data available on the persistence of Ebola virus in survivors' body fluids and the potential risk of transmission, including sexual transmission. Given the urgent need to determine the persistence of Ebola virus in survivors' body fluids, an observational cohort study was designed and implemented during the epidemic response operation in Sierra Leone. This publication describes study implementation methodology and the key lessons learned. Challenges encountered during implementation included unforeseen duration of follow-up, complexity of interpreting and communicating laboratory results to survivors, and the urgency of translating research findings into public health practice. Strong community engagement helped rapidly implement the study during the epidemic. The study was conducted in two phases. The first phase was initiated within five months of initial protocol discussions and assessed persistence of Ebola virus in semen of 100 adult men. The second phase assessed the persistence of virus in multiple body fluids (semen or vaginal fluid, menstrual blood, breast milk, and urine, rectal fluid, sweat, saliva, tears), of 120 men and 120 women. Data from this study informed national and global guidelines in real time and demonstrated the need to implement semen testing programs among Ebola virus disease survivors. The lessons learned and study tools developed accelerated the implementation of such programs in Ebola virus disease affected countries, and also informed studies examining persistence of Zika virus. Research is a vital component of the public health response to an epidemic of a poorly characterized disease. Adequate resources should be rapidly made available to answer critical research questions, in order to better inform response efforts.

    Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly selected from 25 schools in the city of León, Nicaragua. Clinical examinations for dental caries (dmft index) were performed by 2 trained and standardized examiners. Socio-demographic, socioeconomic, and behavioral data were self-reported using questionnaires. Multivariate negative binomial regression (NBR) analysis was used. Mean age was 7.49 ± 1.12 years. Boys accounted for 50.1% of the sample. Mean dmft was 3.54 ± 3.13 and caries prevalence (dmft >0) was 77.6%. In the NBR multivariate model (pBrushing teeth at least once a day and having received preventive dental care in the last year before data collection were associated with declines in the expected mean dmft by 19.5% and 69.6%, respectively. Presence of dental plaque increased the expected mean dmft by 395.5%. The proportion of students with caries in this sample was high. We found associations between dental caries in the primary dentition and dental plaque, brushing teeth at least once a day, and having received preventive dental care. To improve oral health, school programs and/or age-appropriate interventions need to be developed based on the specific profile of caries experience and the associated risk indicators.

    Combustion of biomass fuels (wood and charcoal) for cooking releases smoke that contains health damaging pollutants. Women and children are the most affected. Exposure to biomass smoke is associated with acute respiratory infections (ARI). This study investigated the prevalence of ARI potentially caused by smoke from wood and charcoal stoves in Western Sierra Leone, as these two fuels are the predominant fuel types used for cooking. A cross sectional study was conducted for 520 women age 15–45 years; and 520 children under 5 years of age in homes that burn wood and charcoal. A questionnaire assessing demographic, household and exposure characteristics and ARI was administered to every woman who further gave information for the child. Suspended particulate matter (SPM) was continuously monitored in fifteen homes. ARI prevalence revealed 32% and 24% for women, 64% and 44% for children in homes with wood and charcoal stoves, respectively. After adjusting for potential confounders for each group, the odds ratio of having suffered from ARI was similar for women, but remained large for children in homes with wood stoves relative to charcoal stoves (OR = 1.14, 95%CI: 0.71–1.82) and (OR = 2.03, 95%CI: 1.31–3.13), respectively. ARI prevalence was higher for children in homes with wood stoves compared with homes with charcoal stoves, but ARI prevalence for both types of fuels is higher compared with reported prevalence elsewhere. To achieve a reduction in ARI would require switching from wood and charcoal to cleaner fuels. PMID:22829802

    Full Text Available Mycobacterium africanum is an important cause of tuberculosis (TB in West Africa. So far, two lineages called M. africanum West African 1 (MAF1 and M. africanum West African 2 (MAF2 have been defined. Although several molecular studies on MAF2 have been conducted to date, little is known about MAF1. As MAF1 is mainly present in countries around the Gulf of Guinea we aimed to estimate its prevalence in Cotonou, the biggest city in Benin. Between 2005-06 we collected strains in Cotonou/Benin and genotyped them using spoligo- and 12-loci-MIRU-VNTR-typing. Analyzing 194 isolates, we found that 31% and 6% were MAF1 and MAF2, respectively. Therefore Benin is one of the countries with the highest prevalence (37% of M. africanum in general and MAF1 in particular. Moreover, we combined our data from Benin with publicly available genotyping information from Nigeria and Sierra Leone, and determined the phylogeographic population structure and genotypic clustering of MAF1. Within the MAF1 lineage, we identified an unexpected great genetic variability with the presence of at least 10 sub-lineages. Interestingly, 8 out of 10 of the discovered sub-lineages not only clustered genetically but also geographically. Besides showing a remarkable local restriction to certain regions in Benin and Nigeria, the sub-lineages differed dramatically in their capacity to transmit within the human host population. While identifying Benin as one of the countries with the highest overall prevalence of M. africanum, this study also contains the first detailed description of the transmission dynamics and phylogenetic composition of the MAF1 lineage.

    Full Text Available Background and objectives: In 2012, Sierra Leone suffered a nationwide cholera epidemic which affected the capital Freetown and also the provinces. This study aims to describe the characteristics and clinical management of patients admitted to cholera isolation wards of the main referral hospital in the Northern Province and compare management with standard guidelines. Design: All available clinical records of patients from the cholera isolation wards were reviewed retrospectively. There was no active case finding. The following data were collected from the clinical records after patients had left the ward: date of admission, demographics, symptoms, dehydration status, diagnoses, tests and treatments given, length of stay, and outcomes. Results: A total of 798 patients were admitted, of whom 443 (55.5% were female. There were 18 deaths (2.3%. Assessment of dehydration status was recorded in 517 (64.8% of clinical records. An alternative or additional diagnosis was made for 214 patients (26.8%. Intravenous (IV fluids were prescribed to 767 patients (96.1%, including 95% of 141 patients who had documentation of being not severely dehydrated. A history of vomiting was documented in 92.1% of all patients. Oral rehydration solution (ORS was given to 629 (78.8% patients. Doxycycline was given to 380 (47.6% patients, erythromycin to 34 (4.3%, and other antibiotics were used on 247 occasions. Zinc was given to 209 (26.2%. Discussion: This retrospective study highlights the need for efforts to improve the quality of triage, adherence to clinical guidance, and record keeping. Conclusions: Data collection and analysis of clinical practices during an epidemic situation would enable faster identification of those areas requiring intervention and improvement.

    Although research on the epidemiology and ecology of Ebola has expanded since the 2014-15 outbreak in West Africa, less attention has been paid to the mental health implications and the psychosocial context of the disease for providers working in primary health facilities (rather than Ebola-specific treatment units). This study draws on 54 qualitative interviews with 35 providers working in eight peripheral health units of Sierra Leone's Bo and Kenema Districts. Data collection started near the height of the outbreak in December 2014 and lasted 1 month. Providers recounted changes in their professional, personal and social lives as they became de facto first responders in the outbreak. A theme articulated across interviews was Ebola's destruction of social connectedness and sense of trust within and across health facilities, communities and families. Providers described feeling lonely, ostracized, unloved, afraid, saddened and no longer respected. They also discussed restrictions on behaviors that enhance coping including attending burials and engaging in physical touch (hugging, handshaking, sitting near, or eating with colleagues, patients and family members). Providers described infection prevention measures as necessary but divisive because screening booths and protective equipment inhibited bonding or 'suffering with' patients. To mitigate psychiatric morbidities and maladaptive coping mechanisms-and to prevent the spread of Ebola-researchers and program planners must consider the psychosocial context of this disease and mechanisms to enhance psychological first aid to all health providers, including those in peripheral health settings. © The Author 2016.

    To identify the factors associated with anemia and to document the severity of micronutrient deficiencies, malaria and inflammation, a nationally representative cross-sectional survey was conducted. A three-stage sampling procedure was used to randomly select children anemia (76.3%; 95% CI: 71.8, 80.4), malaria (52.6%; 95% CI: 46.0, 59.0), and acute and chronic inflammation (72.6%; 95% CI: 67.5, 77.1) were high. However, the prevalence of vitamin A deficiency (17.4%; 95% CI: 13.9, 21.6) was moderate, and the prevalence of iron deficiency (5.2%; 95% CI: 3.3, 8.1) and iron-deficiency anemia (3.8%; 95% CI: 2.5, 5.8) were low. Malaria and inflammation were associated with anemia, yet they explained only 25% of the population-attributable risk. In women, 44.8% (95% CI: 40.1, 49.5), 35.1% (95% CI: 30.1, 40.4), and 23.6% (95% CI: 20.4, 27.3) were affected by anemia, malaria, or inflammation, respectively. The prevalence rates of iron deficiency (8.3%; 95% CI: 6.2, 11.1), iron-deficiency anemia (6.1%; 95% CI: 4.4, 8.6), vitamin A deficiency (2.1%; 95% CI: 1.1, 3.1) and vitamin B12 deficiency (0.5%; 95% CI: 0.2, 1.4) were low, while folate deficiency was high (79.2%; 95% CI: 74.1, 83.5). Iron deficiency, malaria, and inflammation were significantly associated with anemia, but explained only 25% of cases of anemia. Anemia in children and women is a severe public health problem in Sierra Leone. Since malaria and inflammation only contributed to 25% of anemia, other causes of anemia, such as hemoglobinopathies, should also be explored. PMID:27163254

    Recent studies on the water waves have been impressive. Of current interest in fluid physics, Jiang et al. [J. Math. Phys. 51, 093519 (2010)] have reported certain soliton interactions along with binary-Bell-polynomial-type Bäcklund transformation and Lax pair for the (2 + 1)-dimensional Boiti-Leon-Pempinelli system for water waves. However, the story introduced by that paper can be made more complete, since in fluid physics and other fields, the variable-coefficient models can describe many physical processes more realistically than their constant-coefficient counterparts. Hereby, on a (2 + 1)-dimensional variable-coefficient Boiti-Leon-Pempinelli generalization, water-wave symbolic computation is performed. For the horizontal velocity of the water wave as well as the wave elevation, variable-coefficient-dependent auto-Bäcklund transformation is constructed out, along with some variable-coefficient-dependent shock-wave-type solutions. Relevant variable-coefficient constraints are also given, with respect to water waves.

     There are few documented examples of community networks that have used unstructured information to support surveillance during a health emergency. In January 2015, the Ebola Response Consortium rapidly implemented community event-based surveillance for Ebola virus disease at a national scale in Sierra Leone. Community event based surveillance uses community health monitors in each community to provide an early warning system of events that are suggestive of Ebola virus disease transmission. The Ebola Response Consortium, a consortium of 15 nongovernmental organizations, applied a standardized procedure to implement community event-based surveillance across nine of the 14 districts. To evaluate system performance during the first six months of operation (March to August 2015), we conducted a process evaluation. We analyzed the production of alerts, conducted interviews with surveillance stakeholders and performed rapid evaluations of community health monitors to assess their knowledge and reported challenges. The training and procurement of supplies was expected to begin in January 2015 and attain full scale by March 2015. We found several logistical challenges that delayed full implementation until June 2015 when the epidemic was past its peak. Community health monitors reported 9,131 alerts during this period. On average, 82% of community health monitors reported to their supervisor at least once per week. Most alerts (87%) reported by community health monitors were deaths unrelated to Ebola. During the rapid evaluations, the mean recall by community health monitors was three of the six trigger events. Implementation of the national system achieved scale, but three months later than anticipated. Community event based surveillance generated consistent surveillance information during periods of no- to low-levels of transmission across districts. We interpret this to mean that community health monitors are an effective tool for generating useful, unstructured

    Full Text Available Abstract Background During December 2014–February 2015, an Ebola outbreak in a village in Kono district, Sierra Leone, began following unsafe funeral practices after the death of a person later confirmed to be infected with Ebola virus. In response, disease surveillance officers and community health workers, in collaboration with local leadership and international partners, conducted 1 day of active surveillance and health education for all households in the village followed by ongoing outreach. This study investigated the impact of these interventions on the outbreak. Methods Fifty confirmed Ebola cases were identified in the village between December 1, 2014 and February 28, 2015. Data from case investigations, treatment facility and laboratory records were analyzed to characterize the outbreak. The reproduction number (R was estimated by fitting to the observed distribution of secondary cases. The impact of the active surveillance and health education was evaluated by comparing two outcomes before and after the day of the interventions: 1 the number of days from symptom onset to case-patient isolation or death and 2 a reported epidemiologic link to a prior Ebola case. Results The case fatality ratio among the 50 confirmed Ebola cases was 64.0 %. Twenty-three cases occurred among females (46.0 %; the mean age was 39 years (median: 37 years; range: 5 months to 75 years. Forty-three (87.8 % cases were linked to the index case; 30 (61.2 % were either at the funeral of Patient 1 or had contact with him while he was ill. R was 0.93 (95 % CI: 0.15–2.3; excluding the funeral, R was 0.29 (95 % CI: 0.11–0.53. The mean number of days in the community after onset of Ebola symptoms decreased from 4.0 days (median: 3 days; 95 % CI: 3.2–4.7 before the interventions to 2.9 days (median: 2 days; 95 % CI: 1.6–4.3 afterward. An epidemiologic link was reported in 47.6 % of case investigations prior to and 100 % after the interventions

    Coverage of skilled delivery care has been increasing across most low-income countries; however, it remains far from universal and is very unequally distributed according to socioeconomic position. In an effort to increase coverage of skilled delivery care and reduce socioeconomic inequalities, governments of several countries in sub-Saharan Africa have recently adopted policies that remove user fees for facility-based delivery services. There is little rigorous evidence of the impact of these policies and few studies have examined effects on socioeconomic inequalities. This study investigates the impact of recent delivery fee exemption policies in Ghana, Senegal, and Sierra Leone on socioeconomic differences in the use of facility-based delivery services. Using Demographic and Health Survey data from nine sub-Saharan African countries, we evaluated the user fee policy changes using a difference-in-differences approach that accounts for underlying common secular trends and time invariant differences among countries, and allows for differential effects of the policy by socioeconomic position. Removing user fees was consistent with meaningful increases in facility deliveries across all categories of household wealth and maternal education. We found little evidence of differential effects of removing user fees across quartiles of household wealth, with increases of 5.4 facility deliveries per hundred live births (95% CI: 2.1, 8.8) among women in the poorest quartile and 6.8 per hundred live births (95% CI: 4.0, 9.7) for women in the richest quartile. However, our results suggest that educated women benefited more from removing user fees compared to women with no education. For women with at least some secondary education, the estimated effect was 8.6 facility deliveries per hundred live births (95% CI: 5.4, 11.9), but only 4.6 per hundred live births (95% CI: 2.2, 7.0) for women with no education (heterogeneity p-value = 0.04). Thus, while removing fees at the point

    Little is understood of Ebola virus disease (EVD) transmission dynamics and community compliance with control measures over time. Understanding these interactions is essential if interventions are to be effective in future outbreaks. We conducted a mixed-methods study to explore these factors in a rural village that experienced sustained EVD transmission in Kailahun District, Sierra Leone. We reconstructed transmission dynamics using a cross-sectional survey conducted in April 2015, and cross-referenced our results with surveillance, burial, and Ebola Management Centre (EMC) data. Factors associated with EVD transmission were assessed with Cox proportional hazards regression. Following the survey, qualitative semi-structured interviews explored views of community informants and households. All households (n = 240; 1161 individuals) participated in the survey. 29 of 31 EVD probable/confirmed cases died (93·5% case fatality rate); six deaths (20·6%) had been missed by other surveillance systems. Transmission over five generations lasted 16 weeks. Although most households had ≤5 members there was a significant increase in risk of Ebola in households with > 5 members. Risk of EVD was also associated with older age. Cases were spatially clustered; all occurred in 15 households. EVD transmission was better understood when the community experience started to concord with public health messages being given. Perceptions of contact tracing changed from invading privacy and selling people to ensuring community safety. Burials in plastic bags, without female attendants or prayer, were perceived as dishonourable. Further reasons for low compliance were low EMC survival rates, family perceptions of a moral duty to provide care to relatives, poor communication with the EMC, and loss of livelihoods due to quarantine. Compliance with response measures increased only after the second generation, coinciding with the implementation of restrictive by-laws, return of the

    We sought to determine the impact of the Ebola virus epidemic on the availability, uptake and outcome of routine maternity services in Sierra Leone. The number of antenatal and postnatal visits, institutional births, availability of emergency obstetric care (EmOC), maternal deaths and stillbirths were assessed by month, by districts and by level of healthcare for 10 months during, and 12 months prior to, the Ebola virus disease (EVD) epidemic. All healthcare facilities designated to provide comprehensive (n=13) or basic (n=67) EmOC across the 13 districts of Sierra Leone were included. Preservice students were not deployed during the EVD epidemic. The number of healthcare providers in facilities remained constant (incidence rate ratio (IRR) 1.03, 95% CI 1.00 to 1.07). Availability of antibiotics, oxytocics, anticonvulsants, manual removal of placenta, removal of retained products of conception, blood transfusion and caesarean section were not affected by the EVD epidemic. Across Sierra Leone, following the onset of the EVD epidemic, there was a 18% decrease in the number of women attending for antenatal (IRR 0.82, 95% CI 0.79 to 0.84); 22% decrease in postnatal attendance (IRR 0.78, 95% CI 0.75 to 0.80) visits and 11% decrease in the number of women attending for birth at a healthcare facility (IRR 0.89, 95% CI 0.87 to 0.91). There was a corresponding 34% increase in the facility maternal mortality ratio (IRR 1.34, 95% CI 1.07 to 1.69) and 24% increase in the stillbirth rate (IRR 1.24, 95% CI 1.14 to 1.35). During the EVD epidemic, fewer pregnant women accessed healthcare. For those who did, an increase in maternal mortality and stillbirth was observed. In the post-Ebola phase, 'readiness' (or not) of the global partners for large-scale epidemics has been the focus of debate. The level of functioning of the health system with regard to ability to continue to provide high-quality effective routine care needs more attention.

Methods The number of antenatal and postnatal visits, institutional births, availability of emergency obstetric care (EmOC), maternal deaths and stillbirths were assessed by month, by districts and by level of healthcare for 10 months during, and 12 months prior to, the Ebola virus disease (EVD) epidemic. All healthcare facilities designated to provide comprehensive (n=13) or basic (n=67) EmOC across the 13 districts of Sierra Leone were included. Results Preservice students were not deployed during the EVD epidemic. The number of healthcare providers in facilities remained constant (incidence rate ratio (IRR) 1.03, 95% CI 1.00 to 1.07). Availability of antibiotics, oxytocics, anticonvulsants, manual removal of placenta, removal of retained products of conception, blood transfusion and caesarean section were not affected by the EVD epidemic. Across Sierra Leone, following the onset of the EVD epidemic, there was a 18% decrease in the number of women attending for antenatal (IRR 0.82, 95% CI 0.79 to 0.84); 22% decrease in postnatal attendance (IRR 0.78, 95% CI 0.75 to 0.80) visits and 11% decrease in the number of women attending for birth at a healthcare facility (IRR 0.89, 95% CI 0.87 to 0.91). There was a corresponding 34% increase in the facility maternal mortality ratio (IRR 1.34, 95% CI 1.07 to 1.69) and 24% increase in the stillbirth rate (IRR 1.24, 95% CI 1.14 to 1.35). Conclusions During the EVD epidemic, fewer pregnant women accessed healthcare. For those who did, an increase in maternal mortality and stillbirth was observed. In the post-Ebola phase, ‘readiness’ (or not) of the global partners for large-scale epidemics has been the focus of debate. The level of functioning of the health system with regard to ability to continue to provide high-quality effective routine care needs more

    It is difficult for sites affected by mining to be colonized by vegetation and thus they suffer a slow recovery to a healthy ecosystem and, as a result, restoration work is necessary. The aim of this report is to propose a set of native species which are conducive to establishing a stable and self-sufficient plant community that will protect the soil and contribute to the rapid integration into the landscape of the areas affected by mining in the upper basin of the river Rodrigatos in the region of El Bierzo (Leon) An analysis of plant communities was undertaken using the phyto sociological method of Braun-Blanquet in order to subsequently select, using ecological criteria, the most suitable species for revegetation. Plant mapping using ortho photos was also developed in order to identify and delineate the location of the different landscape units. Among candidate species, in the first revegetation phase, we suggest a variety of herbs that are able to fix soils and protect them from erosion; species of the genus Cytisus and Genista in areas of moderate slope and species such as Rumex induratus Boiss and Reuter, Erysimum linifolium (Pourr. Ex Pers .) Jay in steeper areas because of their rooting ability. In later stages, the introduction of tree species characteristic for each formation is recommended. Furthermore, in the riverside areas species such as Carex elata subsp.reuteriana (Boiss.) Lucen and Aedo, Alnus glutinosa (L.) and Salix atrocinerea Brot. are proposed for introduction from the fi rst stage onwards. The species proposed in this study include some not commonly used in restoration, so a subsequent more detailed study would be required in order to assess their degree of suitability for this use.

    Full Text Available The mine of Llamas de Cabrera (Leon, Spain is a gold deposit operated during the Roman Empire, in which primary and secondary gold ores coexist. The primary gold ores were hosted mainly in the upper layers of the Armorican Quartzite. They are lodes, being very abundant those hosted in N180°E/70-85°E tensional fractures and rare the ones associated to N70°E and N125°E fractures. They are formed by quartz and arsenopyrite very dominant over pyrite, galena, gold, chalcopyrite, bismuthinite, tetrahedrite and covellite. The accompanying hydrothermal alteration is silicification, sericitization and chloritization. The determined supergene minerals are scorodite, goethite and anglesite. The operated gold is free gold located generally in microfractures in arsenopyrite or quartz. Its content in silver varies from 1,99 to 7,62%, whereas the copper content is very low, remaining below the limit of instrumental detection. This study shows the existence of two phases of mineralization, deposited during two hydrothermal events of hercinian age, in addition to the supergenic phase. The secondary gold ores, operated in alluvial and colluvial sediments, were deployed by the action of the exogenous cycle on the primary gold deposits. We consider that the total volume of material moved at roman time ascended to 2 Mm3.La mina de Llamas de Cabrera (León, España es un yacimiento de oro explotado en época romana, en el que coexisten mineralizaciones de oro primario y de oro secundario.

Though each of them had explored such different literary worlds, their connection point is a space that belongs to everybody's memory, and a common apocryphal character: Sabino Ordás, "patriaren of León's literature". These writers have produced, besides apocryphal, and at the same time they produced their fíctional work, a lavish material of critical reflection. Between metatextual and narrative speech a strong articulation is revealed, and their mechanisms and strategies allow us to state a León's narrative's poetics.

    Full Text Available Background: several diseases such as sepsis can affect the ileum. Lipopolysaccharide (LPS, an endotoxin present in the cell wall of gram negative bacteria, is a causative agent of sepsis. Objectives: the aims of this study were: a to investigate the role of mitogen activated protein kinases (MAPKs in the effect of LPS on the acetylcholine-induced contractions of rabbit ileum; and b to study the localization of MAPKs in the ileum. Material and methods: ileal contractility was studied in an organ bath and MAPKs were localized by immunohistochemistry. Results: acetylcholine-induced contractions decreased with LPS. SB203580, SP600125 and U0126 blocked the effect of LPS on the acetylcholine-induced contractions. Phosphorylated p38 and ERK were detected in neurons of myenteric plexus and phosphorylated p38 and JNK in smooth muscle cells of ileum. Conclusion: we can suggest that p38, JNK, and ERK MAPKs are involved in the mechanism of action of LPS in the ileum.Introducción: varias enfermedades como la sepsis pueden afectar al íleon.

    Full Text Available La declinación de Abies religiosa en el Desierto de los Leones, D. F. es un proceso del que a la fecha muchos aspectos han sido poco estudiados, lo que ha dificultado la cabal comprensión de las causas del fenómeno. En el presente trabajo se estudió el estado nutrimental de la especie, relacionándolo con el grado en que se presentan dos de los principales síntomas, la clorosis y el enrojecimiento del follaje. Se seleccionaron muestras de follaje de aproximadamente 1.5 años de edad de A. religiosa con presencia de cada uno de los síntomas en cinco diferentes grados, 0, 25, 50, 75 y 100. Cada uno de los grados de cada síntoma fueron replicados cinco veces y los datos fueron procesados mediante análisis de varianza. Los resultados indican una relación inversa entre el grado de clorosis y las concentraciones de N, P y K en presencia de deficiencias de Mg y Mn. El enrojecimiento del follaje parece estar relacionado con deficiencias de N, acompañadas por deficiencias generalizadas de K, Mg y Mn.

    Full Text Available Trifolium rubens L. is a leguminous plant “Preferential Attention”, according to the Catalog of Protected Flora of Castile and Leon (Spain. In this study we aimed to analyze the potential of three bacterial strains of the genus Rhizobium to improve the growth and development of this plant. All three strains produced 3-indoleacetic acid (IAA, but the strain ATCC 14480 produced the most. In addition, all strains produced biofilms and cellulases, although in different quantities. The synthesis of these products has been described as being related to the processes of the adherence of bacteria to the plant root surface and their entrance into the plant, respectively. In addition, in vitro assays and assays conducted under controlled and sterile conditions were performed, showing that the three strains were capable of nodulating T. rubens L. and effectively fixed nitrogen for the plant. These results were corroborated by morphological and histological analysis of nodules. Finally, greenhouse assays determined the effects of the strains under more competitive conditions, and it was concluded that inoculated plants presented greater lengths and weights, both aerial and radicular, and also chlorophyll and nitrogen content compared to the uninoculated controls.

    Full Text Available Halving the burden of malaria by 2015 and ensuring that 80% of people with malaria receive treatment is among the health related targets of the Millennium Development Goals (MDGs. Despite political momentum toward achieving this target, progress is slow and many with malaria (particularly in poor and rural communities in Africa are still without access to effective treatment. Finding ways to improve access to anti-malarial treatment in Africa is essential to achieve the malaria related and other MDG targets. During its work in Chad, Sierra Leone and Mali in the period 2004 to 2008, Médecins Sans Frontières showed that it was possible to significantly improve access to effective malaria treatment through: i the removal of health centre level user fees for essential healthcare for vulnerable population groups, ii the introduction of free community based treatment for children using malaria village workers to diagnose and treat simple malaria in communities where geographical and financial barriers limited access to effective malaria care, iii the improved diagnosis and treatment of malaria using rapid diagnosis tests and artemisinin based combination therapy, at both health facilities and in the community. This paper describes and discusses these strategies and their related impact.

Traditionally centered on teaching the academic community at this institution, the School began moving towards a heavier emphasis on research when Professor Giovanni Marini Bettolo arrived in Uruguay in 1948. The article examines Bettolo's role and the role of the researchers trained by him and his successors. This is a preliminary approach to the study of the quantitative and qualitative impact that this set of teachers had within overall research production in chemistry in Uruguay; it is meant as a first step that lays a foundation for future studies of the topic.

    Da Monte was a very important member of medical Humanism; his position within the medical cultural scene of his time was characterised by strong interests in the epistemological problems of medicine. He considered the whole medicine - not only theory - a practical science according to the Aristotelian concept of science. During his teaching years at the Paduan Studium he tried to overcome the division of medicine into medical theory and medical practice and he elaborated an unitary method of teaching, trying to follow the Galen's Methodus medendi, in order to give a true scientific foundation also to the medical practice.

    In November 2009, Sierra Leone conducted a preventive yellow fever (YF) vaccination campaign targeting individuals aged nine months and older in six health districts. The campaign was integrated with a measles follow-up campaign throughout the country targeting children aged 9-59 months. For both campaigns, the operational objective was to reach 95% of the target population. During the campaign, we used clustered lot quality assurance sampling (C-LQAS) to identify areas of low coverage to recommend timely mop-up actions. We divided the country in 20 non-overlapping lots. Twelve lots were targeted by both vaccinations, while eight only by measles. In each lot, five clusters of ten eligible individuals were selected for each vaccine. The upper threshold (UT) was set at 90% and the lower threshold (LT) at 75%. A lot was rejected for low vaccination coverage if more than 7 unvaccinated individuals (not presenting vaccination card) were found. After the campaign, we plotted the C-LQAS results against the post-campaign coverage estimations to assess if early interventions were successful enough to increase coverage in the lots that were at the level of rejection before the end of the campaign. During the last two days of campaign, based on card-confirmed vaccination status, five lots out of 20 (25.0%) failed for having low measles vaccination coverage and three lots out of 12 (25.0%) for low YF coverage. In one district, estimated post-campaign vaccination coverage for both vaccines was still not significantly above the minimum acceptable level (LT = 75%) even after vaccination mop-up activities. C-LQAS during the vaccination campaign was informative to identify areas requiring mop-up activities to reach the coverage target prior to leaving the region. The only district where mop-up activities seemed to be unsuccessful might have had logistical difficulties that should be further investigated and resolved.

    Full Text Available Pour la réforme de la justice ottomane: Count Leon Walerian Ostroróg (1867–1932 and his activities in the final decades of the Ottoman Empire Following the final partition of the Polish-Lithuanian Commonwealth in 1795 the Ottoman Empire became one of the chief destinations for the Polish political émigrés. Poles fled to Istanbul hoping for Ottoman support in their efforts to regain independence. Their participation in the Ottoman public sphere was not limited to the activities aimed at the restoration of an independent Poland; rather, Polish émigrés also played an active role in the enterprise of modernization of the Ottoman state since the era of the Tanzimat reforms (1839–1876. While one can say that the intensity of the Polish participation in the Ottoman public sphere decreased substantially after the Ottoman defeat in the war against Russia (1877 –1878 and during the reign of Sultan Abdülhamid II (r. 1876–1909, the subsequent 1908 Young Turk Revolution and the coming to power of the Committee of Union and Progress (İttihat ve Terakki Fırkası was a watershed event that attracted some Polish émigrés from France to come to the Ottoman Empire. This paper focuses on the work of Count Leon Ostroróg (1867–1932, who came to prominence as a legal adviser to the Ottoman Ministry of Justice in the Second Constitutional Period (1908–1918. He played an important role in the reform projects of the Ottoman legal system. Meanwhile, he was actively engaged in the life of the Istanbul’s Polish, French and Levantine communities. By focusing on his major works this paper discusses Ostroróg’s views on the late Ottoman Empire and his stance towards the transformation of the multicultural and multiethnic Ottoman Empire into the nation-state of the Republic of Turkey in the aftermath of the WWI and towards a number of far-reaching reforms that characterized that period.   Pour la réforme de la justice ottomane: Hrabia Leon Walerian

    Full Text Available Urban growth and its associated expansion of built-up areas are expected to continue through to the twenty second century and at a faster pace in developing countries. This has the potential to increase thermal discomfort and heat-related distress. There is thus a need to monitor growth patterns, especially in resource constrained countries such as Africa, where few studies have so far been conducted. In view of this, this study compares urban growth and temperature response patterns in Freetown and Bo town in Sierra Leone. Multispectral Landsat images obtained in 1998, 2000, 2007, and 2015 are used to quantify growth and land surface temperature responses. The contribution index (CI is used to explain how changes per land use and land cover class (LULC contributed to average city surface temperatures. The population size of Freetown was about eight times greater than in Bo town. Landsat data mapped urban growth patterns with a high accuracy (Overall Accuracy > 80% for both cities. Significant changes in LULC were noted in Freetown, characterized by a 114 km2 decrease in agriculture area, 23 km2 increase in dense vegetation, and 77 km2 increase in built-up area. Between 1998 and 2015, built-up area increased by 16 km2, while dense vegetation area decreased by 14 km2 in Bo town. Average surface temperature increased from 23.7 to 25.5 °C in Freetown and from 24.9 to 28.2 °C in Bo town during the same period. Despite the larger population size and greater built-up extent, as well as expansion rate, Freetown was 2 °C cooler than Bo town in all periods. The low temperatures are attributed to proximity to sea and the very large proportion of vegetation surrounding the city. Even close to the sea and abundant vegetation, the built-up area had an elevated temperature compared to the surroundings. The findings are important for formulating heat mitigation strategies for both inland and coastal cities in developing countries.

Conclusions The majority of the pre-ART LTFU population stopped their care, particularly after ART-eligibility but before ART initiation. Interventions to hasten ART initiation and retain this at-risk group may have significant downstream impact on effective HIV care. PMID:26901765

    Full Text Available OBJECTIVE: The effects of alcohol on mortality due to motor vehicle accidents was studied. MATERIAL AND METHODS: During the first semester of 2003, a sample of 243 fatality victims of traffic-related accidents and their blood alcohol levels were analyzed in the state of Nuevo Leon, Mexico. The age-adjusted mortality rate for traffic accidents was 8.9/100000 pop. (13.2 for males and 3.21 for females, per 100000. Fatal accidents were more common in the Metropolitan Area (MA. RESULTS: Fatalities were four times greater in males and the mean age was 34.7±18.2 years. Blood alcohol was detected in almost half of the victims who were drivers of the vehicles; the other cases of fatalities may be associated with road/car condition, weather and other factors. CONCLUSIONS: Alcohol intoxication levels were primarily associated with male drivers ages 16 to 45 (p=0.029; levels increased with age. In females, alcohol played a lesser role, affecting mostly ages 31 to 45 y (p=0.055.OBJETIVO:Durante seis meses de 2003 se estudió el efecto del alcohol en 243 víctimas fatales relacionadas con accidentes viales del estado de Nuevo León, México. MATERIAL Y MÉTODOS: Se realizó autopsia en todos los casos y se determinó el nivel de alcohol en sangre. La tasa de mortalidad ajustada por edad para accidentes viales fue 8.9/100000 hab. (13.2 para hombres y 3.21 para mujeres, por 100000. Accidentes fatales fueron comunes en el Área Metropolitana. RESULTADOS: Las fatalidades fueron cuatro veces mayores en hombres y la edad promedio fue de 34.7±18.2 años. Se detectaron niveles de alcohol en sangre en casi la mitad de los conductores que fueron víctimas; los otros casos de fatalidad fueron asociados con las condiciones del camino, el auto, factores meteorológicos, entre otros. CONCLUSIONES: Los niveles de intoxicación alcohólica fueron básicamente con conductores masculinos, de 16-45 años (p=0.029, aumentando con la edad. Entre las mujeres, el alcohol jugó un

    Dentistry has a long, often well documented history. Evidence of tooth pullings has been discovered in crude carvings on the walls of caves that are over 10,000 years old. The ancient Egyptians, the Athenians, and the early inhabitants of Rome required oral health care; in addition to tooth extractions, they underwent tumor removal, tamponade for hemorrhage, reduction of jaw fractures with gold wire ligatures, cautery using white hot platinum loops, and an additional variety of remedies and nostrums. Pain relief was offered, with courses of treatment as varied as postural change, alteration of ambient temperature, and vegetable and organic medicines in poultices or via oral and rectal routes. Through the centuries, great surgeons and physicians introduced various methods of treatment: Hippocrates codified ethical standards; Maimonides established pragmatic rules for physicians; LeFort categorized facial fractures; Pasteur clarified the need for sterilization; Semmelweis standardized antiseptic conditions in the operating theater; Morton and Wells discovered safer methods of analgesia; Freud explored the theraupeutic uses of narcotics; Roentgen championed X-ray imaging; Curie pioneered the use of chemotherapy; and Barton and Nightingale were models of empathy and patient care. In more recent times, we have profited from the genius of Watson and Crick (DNA); Fleming (penicillin); Venable and Stuck (Chrome-cobalt--molybdenum alloy); Gershkoff and Goldberg (the subperiosteal implant); Chercheve, Branemark, Linkow, Misch, Tatum, and Niznick (innovative root forms, titanium and its alloys, and sinus floor grafting). The 20th century has brought to us phenomenal imaging, breathtaking intrauterine fetal surgery, wildly promising stem cell research, and astonishing CADCAM techniques. We've had great teachers and clinicians who have introduced us to new forms of therapy and advanced methods, including the role of the hemidesmasomes, the essential elements of bone grafting, the importance of microscopic analysis, and the benefits to patients of physical diagnosis by their dentists. To recognize and celebrate some of my heroes' contributions to the health and well-being of humankind, editorials will occasionally appear on these pages that explore their various contributions.

Pacientes y método:Los datos dentales de una muestra representativa de 1.400 niños escolares fueron recogidos y analizados en un estudio transversal (año 2002. Todos los sujetos fueron examinados visual y clínicamente por uno de los 2 examinadores capacitados y estandarizados. Resultados: El 28,6% de los niños estaba libre de caries en ambas denticiones. La prevalencia de caries en la dentición temporal a los 6 años de edad fue del 72,6% y la de la dentición permanente a los 12 años fue del 45,0%. El SiC fue 4,12 en los niños de 12 años de edad. La media de los índices de caries (ceod y CPOD para la muestra fue 2,98 ± 2,93 (n = 1.125 y 0,65 ± 1,43 (n = 1.379. Los niños con antecedentes de caries en la dentición temporal tuvieron mayor probabilidad de presentar caries en la dentición permanente (odds ratio = 2,48; intervalo de confianza del 95%, 1,66-3,79. Conclusión: Se observó una baja prevalencia de caries en la dentición permanente con un alto porcentaje de dientes obturados, a diferencia de lo observado en la dentición temporal. A unos años de las metas propuestas para el año 2000 (FDI/OMS, no se cumplieron los objetivos en los niños de 6 años de edad.

    Full Text Available This article focuses on a specific aspect of the work of G.B. Piranesi: the knowledge of the technical engineering elements linked to the Venetian author’s education. His entire works have been studied in order to find the greatest number of references to help to understand Roman building technology filtered by the original shape of the designs on the illustrations. In this sense, several groups of graphic representations have been identified allowing us to establish a connection with the world of construction which is evident in all of the illustrations that deal with older buildings. Our goal is to reevaluate the details in the works of Piranesi which try to penetrate in the anatomy of Roman structures aiming to learn and show «how» they were built.En este artículo se ha prestado atención a un aspecto específico de la obra de G. B. Piranesi: el conocimiento de los elementos técnico-constructivos de la arquitectura romana. Se ha realizado un análisis de la totalidad de su obra, en el intento de encontrar el mayor número posible de referencias útiles para la comprensión de la tecnología edilicia romana, filtrada por la forma original de las composiciones de las láminas. En este sentido, se han identificado varios grupos de representaciones gráficas que nos permiten plantear la presencia de un hilo conductor constante en relación con el mundo de la construcción, evidente en la casi totalidad de láminas que tratan edificios antiguos. El objetivo final es la reevaluación de aquellos detalles de las obras de Piranesi que intentan penetrar en la anatomía de las estructuras romanas para aprender y demostrar las modalidades constructivas.

    Conociendo el descenso que se produce en la práctica deportiva al entrar en la Universidad, y la relación existente entre el consumo de sustancias nocivas y la falta de ejercicio físico, hemos querido estudiar si esto también ocurre en los estudiantes de Ciencias de la Actividad Física y el Deporte. Con este objetivo pasamos un cuestionario elaborado por nosotras a estudiantes de nuestra Facultad dónde  analizamos: 1º, motivaciones y actitudes de los alumnos de los diversos cursos hacia la carrera, así como sus preferencias profesionales; 2º, si se ha producido un descenso en la práctica física al estudiar la carrera; y 3º, qué hábitos de consumo de tabaco y alcohol tenían nuestros estudiantes antes de entrar en la Facultad y cómo evolucionan durante la carrera. Entre los resultados más relevantes cabe destacar la marcada disminución de la práctica deportiva al iniciar la carrera; la caída de la motivación hacia estos estudios según avanzan los cursos, y finalmente, que el porcentaje de alumnos que consumen alcohol es alto y aumenta a lo largo de la carrera, ocurriendo lo contrario con el tabaco.
    PALABRAS CLAVE: Práctica deportiva, actitudes, motivación, alcohol y tabaco.

    Full Text Available Education plays a key role in the process of rehabilitation and reintegracion of child soldiers and helps them to overcome the psysologial and moral impact of the war. Children see education as their gateway to a different life away from the violence and suffering they experienced during the years lived with the armed grups. The desire to change life makes children strive in this activity devouting great effort to stand out above the rest of their classmates. The disruption of the educational process generates great frustration for former child soldiers. Therefore, all reintegration and rehabilitation programs must invest time and resources to ensure that these children have secured their training until the end.

  13. The influence of the masonry mechanical properties in the structural behaviour of the Leon`s cathedral

    Directory of Open Access Journals (Sweden)

    Gálvez Ruiz, J. C.

    2009-06-01

    Full Text Available Mechanical and physical properties of the masonry have a considerable bearing on the structural behaviour. Ancient buildings, like Leon’s cathedral, show uncertainty about real condition of the material and even structural compounds. These uncertainties make it difficult to assessment the bearing capacity of the structure and the affect of the restorations. This paper shows a study to select the most influential material’s parameters on the structural behaviour. The study is based on a sensitiveness analysis.The study starts with a structural analysis to select the most responsible areas of the transversal structural section. Then, the structural calculation is done by modifying the value of the material’s parameters in the expected scatter band. The statistical study provides the most influential parameters on the structural masonry behaviour. Finally the conclusions are proponed.Las propiedades de un material como la fábrica influyen de forma determinante en el comportamiento de la estructura. En una estructura histórica, como la catedral de León, se añade la incertidumbre del estado real del material y la composición de sus elementos estructurales. Estos aspectos dificultan la evaluación de la capacidad resistente de la estructura y la incidencia de actuaciones de reparación o remodelación. Este trabajo presenta el estudio realizado para seleccionar, mediante un análisis de sensibilidad del comportamiento de la estructura, cuáles son las variables del material que más afectan al comportamiento estructural de la catedral.El estudio se inicia con el análisis estructural de la sección tipo para identificar las zonas de mayor responsabilidad. A continuación se hace el estudio estructural con la combinación de todas las variables, especialmente las dependientes de los materiales, modificando su valor. Mediante un tratamiento estadístico de los resultados, se determina qué parámetros de los adoptados afectan más al comportamiento de la estructura de fábrica y se establecen las conclusiones.

    The Bierzo Basin presents large coal mining structures without restore where the air exposition of metallic sulphurs could become a source of heavy metal pollution and acification of waters. This paper presents the results of a research focused on groundwater quality affected by the mining activity. A sampling campaign of both ground and surface waters was carried out. Altogether, 37 sampling points has been selected including 26 springs, 7 shallow wells for agricultural use and 4 river water samples, all of them directly or indirectly connected to groundwater. The interpretation of results is based on the multivariate analysis application. Sulphate is the dominant anion in both water types, and it is related, in most cases, to oxidation of sulphurs, widely represented in the study area. However, the main conclusion is that surface water and groundwater samples have no high abnormal contents of heavy metals due to the induced alteration by mining activity. (Author) 15 refs.

    The unequivocal origin of the red sandstone used for Astorga cathedral was studied in this paper. This red sandstone presents distinctive hydrothermal minerals filling fractures, the most conspicuous are anatase crystals with characteristic habit, colour and transparency, quite rare in the region. The identification of fractures filled with this TiO{sub 2} polymorph in an abandoned sandstone quarry south of Astorga allowed us to confirm the origin of the rock used for one of the towers of Astorga cathedral.

    Amparo Lopez-Bernus

    Full Text Available Cystic echinococcosis (CE is an important health problem in many areas of the world including the Mediterranean region. However, the real CE epidemiological situation is not well established. In fact, it is possible that CE is a re-emerging disease due to the weakness of current control programs.We performed a retrospective observational study of inpatients diagnosed with CE from January 2000 to December 2012 in the Western Spain Public Health-Care System.During the study period, 5510 cases of CE were diagnosed and 3161 (57.4% of the cases were males. The age mean and standard deviation were 67.8 ± 16.98 years old, respectively, and 634 patients (11.5% were younger than 45 years old. A total of 1568 patients (28.5% had CE as the primary diagnosis, and it was most frequently described in patients 70 year old associated with other causes of comorbidity. The period incidence rate was 17 cases per 105 person-years and was significantly higher when compared to the incidence declared through the Notifiable Disease System (1.88 cases per 105 person-years; p<0.001.CE in western Spain is an underestimated parasitic disease. It has an active transmission, with an occurrence in pediatric cases, but has decreased in the recent years. The systematic search of Hospital Discharge Records of the National Health System Register (HDR may be a more accurate method than other methods for the estimation of the incidence of CE in endemic areas.

  9. A metalogenic pattern for the uraniferous ore deposits at the Sierrita Nuevo Leon and Tamaulipas area

    Hernandez H, A.

    1977-01-01

    A metalogenic pattern is proposed as a geological criterion to help in prospecting radioactive minerals accumulated in the tertiary sedimentary deposits at the Burgos Basin. Through the analysis and interpretation of the geological concepts and the mentioned pattern we can reach more and more precise processes to control the localization of radioactive minerals and at the same time apply the criteria of this pattern in the selection of areas which present the greatest probabilities of the existence of a radioactive ore deposit. As soon as the geoligical is defined, prospection programs are realized with indirect methods through which we obtain the demarcation of anomalous superficial zones. Immediately after this step a geological and geophysical verification program is developed. This way we can know objectively the areas which will be included in the direct exploration programm that will permit us to determine finally the zones of interest and the uninteresting zones. In conclusion the objective of this work is to determine the relations between paleochannels and accumulations of radioactive minerals. (author)

    Guizar, Juan Manuel; Muñoz, Nathalie; Amador, Norma; Garcia, Gabriela

    To determine the association between types of food consumed, nutritional status (BMI) and caries in schoolchildren. A cross-sectional study was performed with 224 schoolchildren 6 to 12 years of age. DMFT/ dmft indices, level of oral hygiene, nutritional status as quantified by BMI and types of food consumed were determined in all participants. Data were analysed using multiple linear regression with significance set at p Caries prevalence was 36%. In the multiple linear regression analysis adjusted for BMI, variables related to a higher number of caries were younger age and lower intake of vitamin D, calcium and fiber, with higher consumption of phosphorous and carbohydrates (R2 = 0.30; p caries prevalence, while consuming milk and carrots were protectors. Caries in schoolchildren is highly prevalent in this community and is related to younger age and lower intake of vitamin D, calcium and fiber, but a higher consumption of phosphorous and carbohydrates. No relationship was found between caries and nutritional status.

  2. Louis Leon Thurstone in Monte Carlo: creating error bars for the method of paired comparison

    Science.gov (United States)

    Montag, Ethan D.

    2003-12-01

    The method of paired comparison is often used in experiments where perceptual scale values for a collection of stimuli are desired, such as in experiments analyzing image quality. Thurstone's Case V of his Law of Comparative Judgments is often used as the basis for analyzing data produced in paired comparison experiments. However, methods for determining confidence intervals and critical distances for significant differences based on Thurstone's Law have been elusive leading some to abandon the simple analysis provided by Thurstone's formulation. In order to provide insight into this problem of determining error, Monte Carlo simulations of paired comparison experiments were performed based on the assumptions of uniformly normal, independent, and uncorrelated responses from stimulus pair presentations. The results from these multiple simulations show that the variation in the distribution of experimental results of paired comparison experiments can be well predicted as a function of stimulus number and the number of observations. Using these results, confidence intervals and critical values for comparisons can be made using traditional statistical methods. In addition the results from simulations can be used to analyze goodness-of-fit techniques.

    Full Text Available In this article I examine Leonese nobility networks as a means to explain the involvement by Prince Alfonso of Castille (later King Alfonso X in the civil war that confronted King Sancho II of Portugal with his brother Prince Alfonso, later Alfonso III of Portugal. Prosopography allows to reconstruct family bonds linking Leonese and Galician noblemen who had joined Prince Alfonso of Castille with their Portuguese counterparts who had rallied behind King Sancho. I will aim to prove that, following the alarm triggered by their Portuguese relatives, family bonds prompted Leonese and Galician noblemen to take part in the war and to seek Prince Alfonso of Castille’s support, after his father, King Ferdinand III, refused it.

    Hofmann-Winkler, Heike; Gnirß, Kerstin; Wrensch, Florian; Pöhlmann, Stefan

    2015-10-01

    The ongoing Ebola virus (EBOV) disease (EVD) epidemic in Western Africa is the largest EVD outbreak recorded to date and requires the rapid development and deployment of antiviral measures. The viral glycoprotein (GP) facilitates host cell entry and, jointly with cellular interaction partners, constitutes a potential target for antiviral intervention. However, it is unknown whether the GPs of the currently and previously circulating EBOVs use the same mechanisms for cellular entry and are thus susceptible to inhibition by the same antivirals and cellular defenses. Here, we show that the GPs of the EBOVs circulating in 1976 and 2014 transduce the same spectrum of target cells, use the same cellular factors for host cell entry, and are comparably susceptible to blockade by antiviral interferon-induced transmembrane proteins and neutralizing antibody KZ52. Thus, the viruses responsible for the ongoing EVD epidemic should be fully susceptible to established antiviral strategies targeting GP and cellular entry factors. © The Author 2015.

    Directory of Open Access Journals (Sweden)

    Javier Moreno Lázaro

    2009-04-01

    Full Text Available This article contributes to the field of anthropometric history, recently of great interest to social and economic historians. An analysis of the height of adult males in Spain’s interior provides a reflection of the nutritional state and biological wellbeing of the society of that region during Spain’s industrialization. Some 29,000 registers relating to military drafts between 1830 and 1940 provide a series of samples of the rural and urban populations of Castilla-León which allow for an analysis of territorial, environmental, and social inequalities, as well as cyclical changes. This analysis reveals that height in this region developed according to a cyclical model determined by environmental and economic factors, diminishing during the second half of the nineteenth century, when malnutrition and under-nutrition were more prevalent in Castilla-León than in other Spanish regions, and not picking up again before the early twentieth century. This reduction in height was more evident in urban environments and among day-labourers. The nutritional status of this region’s population improved significantly during the first half of the twentieth century. Although it was affected during the Civil War and post-war period, this decline was not as great as that experienced in other regions of Spain.

  9. Weathering of PGE sulfides and Pt-Fe alloys in the Freetown Layered Complex, Sierra Leone

    Science.gov (United States)

    Bowles, John F. W.; Suárez, Saioa; Prichard, Hazel M.; Fisher, Peter C.

    2017-12-01

    Fresh and weathered rocks and saprolite from Horizon B of the Freetown Layered Complex contain platinum-group minerals (PGM). The PGM in the fresh rocks are 1-7 μm across, including cooperite (PtS), isoferroplatinum (Pt3Fe), minor tetraferroplatinum (PtFe), tulameenite (Pt2FeCu), Os-bearing laurite (RuS2), and other base metal-sulfide (BMS)-bearing PGM. The weathered rocks contain fewer of those PGM but a high proportion of disordered Cu-(±Pd)-bearing Pt-Fe alloys. The saprolite hosts scarce, smaller (1-3 μm) ordered PtFe and disordered PtFe3. The Pt-Fe alloys became increasingly Fe rich as weathering proceeded. Pt-Fe oxides appeared during weathering. Copper sulfides associated with the primary PGM and cooperite (with <3% Pd) were destroyed to provide the minor Cu and Pd found in some of the disordered Pt-Fe alloys. Platinum- and Pd-bearing saprolites have retained the original rock fabric and, to a depth of about 2 m, surround residual rocks that show progressive weathering (corestones). Ground water passing through the saprolite has transported Pt and Pd (and probably Au) in solution down slope into saprolite over unmineralized rocks. Transport is marked by changes in the Pt/Pd ratio indicating that the metals have moved independently. Palladium is present in marginally higher concentrations in the deeper saprolite than in the corestones suggesting some retention of Pd in the deeper saprolite. Platinum and Pd are less concentrated in the upper saprolite than the deeper saprolite indicating surface leaching. Alteration occurred over a long period in an organic and microbial rich environment that may have contributed to the leaching and transport of PGE.

    Full Text Available Music played an outstanding role in seventeenth-century Spanish court theatre, even to the point of being a factor when considering whether the plays were to be staged in the royal palace or staged only in the popular theatres or corrales. But it was in the royal playhouses where a number of new musical-dramatic new genres developed. In other words, different types of plays were characterized by their musical components, as in for example, El baile de las aves [The Dance of the Birds] by Melchor Fernández de León, a text that was first staged in the Royal Palace in 1684, on occasion of the birthday of Queen María Luisa, wife to King Carlos II. Music, dancing and singing contribute greatly to turn the representation of the play into a very brilliant event.

    Losa, A. de la; Moreno, L.; Nunez, I.

    2010-01-01

    The Bierzo Basin presents large coal mining structures without restore where the air exposition of metallic sulphurs could become a source of heavy metal pollution and acification of waters. This paper presents the results of a research focused on groundwater quality affected by the mining activity. A sampling campaign of both ground and surface waters was carried out. Altogether, 37 sampling points has been selected including 26 springs, 7 shallow wells for agricultural use and 4 river water samples, all of them directly or indirectly connected to groundwater. The interpretation of results is based on the multivariate analysis application. Sulphate is the dominant anion in both water types, and it is related, in most cases, to oxidation of sulphurs, widely represented in the study area. However, the main conclusion is that surface water and groundwater samples have no high abnormal contents of heavy metals due to the induced alteration by mining activity. (Author) 15 refs.

    The area was studied and explored in an indirect way: geochemistry and geophysics, through radiometric and emanometric detection, together with analysis of the geological factors made possible the geological interpretation of the area. The studied deposit is of the supergenic type and is situated in a sandy body which has a thickness of 8 to 13 meters and belongs to the Frio no Marino Formation. An intensification of the explorations is recommended in all the other parts of the Burgo Basin, mainly in the Oligocenic zone, and it is suggested to make more objective the radiometric aerial surveys. We conclude that we have to take into consideration the economical importance of the Buenavista deposit since it represents a potencial richness of approxiamately, 2,000 million pesos, on the basis of the present cost of the uranium ore.

  3. Fate and Reactive Transport of Chromium in Leon Valley, Guanajuato, Mexico Using Stable Isotopes

    Science.gov (United States)

    Villalobos-Aragón, A.; Ellis, A. S.; Armienta, M. A.; Morton, O.; Johnson, T. M.

    2007-12-01

    Chromium (Cr) is commonly found in the environment due to both anthropogenic and natural sources. Cr(VI) is highly mobile, toxic and carcinogenic, while Cr (III) is less mobile. Reduction of Cr (VI) to Cr (III) is a remediation technique frequently proposed, so monitoring it becomes essential in remediation efforts. It has been previously proposed that Cr stable isotopes may be useful in differentiating Cr(VI) reduction from other transport processes. The goals of this study, at a chromate production facility in León México are: 1) use the stable isotope values (δ53Cr), to monitor Cr transport, 2) verify sources of contamination, and test the hypothesis that it is both anthropogenic and natural, and 3) monitor isotopic fractionation during transport of Cr in sediment columns, to better understand and model the processes taking place during transport. León is located in central México, and is one of its most important industrial centers. Several studies have been performed in the León Valley, since Cr was first detected in its groundwater in 1975. It has been proposed that the high concentration plume near the factory is anthropogenic, while the large sub ppb plume is caused by weathering from ultramafic rocks. Sediment samples were collected from two waste piles in the chromate factory, water was sampled from wells and piezometers near the factory and surface water from the Juan de Otates Dam area near ultramafic rock outcrops. To complement the field study, two types of experiments were performed: 1) the 1-D column flow experiments with sand, goethite coated sands and sand-magnetite mixtures, and 2) leaching experiments of sediments from the two waste piles. Cr(VI) concentrations for the surface water range from 0.009mg/L to 0.015mg/L, and for groundwater from 0.008 mg/L to 121 mg/L. Surface collection ponds for waste pile leachates range from 1.2 to 3.8 g/L. The δ53Cr values for groundwater range from 0.33‰ to 0.46‰ near the factory indicating minimal reduction in the area. The large amounts of Cr have probably exhausted natural reductants. Leaching experiment samples have enriched δ53Cr values (0.76‰ to 3.25‰) indicating either varying reduction or that the waste is fractionated during the ore processing. The difference in δ53Cr values in groundwater and those coming from the waste piles, previously considered to be the source of the contamination, suggests the presence of other Cr sources. The 1-D columns experiments conducted have δ53Cr values that fall within our precision indicating that the isotopes are not fractionated during non- reactive transport processes, including sorption and the lack of variation in the groundwater plume are consistent with the results. Ongoing work includes analyzing the larger Cr plume hypothesized to be of natural origin and rivers draining the ultramafic rocks.

    Full Text Available As humans evolved, similarities and differences began to appear, resulting from genetic inheritance and infl uenced by the environment in which each individual develops. This results in a variety of shapes, sizes, proportions, composition, function etc. Anthropometry has its origins in medicine or biology and the fi ne arts. The Old Testament, the Babylonian Talmud, the Midrashim and treatises from the civilization of India all refer to the shape, proportions and stature of the human form. Scholars such as Empedocles, Socrates and Hipocrates concerned themselves with these relationships and created a variety of classifi cations of an ideal mode for man. Polyklitus, a Greek sculptor, represented the ideal male form by means of superimposition of anatomical parts of twenty individuals. Archimedes’ theory of the fl otation phenomenon made it possible for body composition to be calculated from densitometry today. Others, such as Leonardo da Vinci, Michelangelo and Leone Alberti concerned themselves with establishing a type for ideal beauty. Vesalius began to discuss and dispute the theiories of Galeno. During this period anthropometry emerges as a new scientifi c specialty. Borelli explains muscular work in terms of physics. His work is valid for describing the structural bases of cineanthropometry. Elshaltz was the first to use the term anthropometry in its modern sense.

    The study tackles the environmental impact on aquatic ecosystems caused by coal mining activity in the Carboniferous Area of El Bierzo. This survey is based on the methodology of the USGS (Geological Survey of the United States of America) Assessment of Metal Bioavailability in a Watershed Affected by Abandoned Mine Lands. The application of this methodology to the mining area of El Bierzo, with a declining coal mining that entails the closure of many underground mines and the dismantling of the coal washing plants, has allowed to assess, in time and distance to contamination sources, the impact, environmental quality, and the attenuation and natural recovery processes of the aquatic ecosystems, once the mines are closed.

    Ubillos, Silvia; Centeno, Javier; Ibañez, Jaime; Iraurgi, Ioseba

    2015-03-01

    The aim of this research was to know the protective and risk factors associated with voice strain in teachers. A total of 675 teachers from Castille and León, Spain took part in the research within an age range between 23 and 66 years (from nursery school to university). A cross-sectional, descriptive, and analytic design was applied to data from a self-administered questionnaire. The research showed that 16.4% had suffered some voice disorder and a remarkable percentage had never received any kind of voice training. The bivariate and multivariate analyses show that the size of the classroom, being a primary school teacher, teaching physical education, the noise caused by the students in the classroom, the struggle to keep the order within the class, raising the voice, and bad sleep are risk factors in the voice disorders. Each learning stage features a different risk factor, namely in nursery school, the noise caused by the pupils; in primary education, raising the voice; and in secondary education, the struggle to keep the order within the class. All these risk factors are linked with each other. The preventive measures must provide adequate answers to the voice requirements for every subject and stage, and these preventive measures must be based on the educational psychology principles to help the teachers deal with the problems originated by the lack of authority or the noise made by the students, using the proper voice techniques.

  13. The humble in a context of "greatness": challenges facing the regeneration of Barrio Antiguo in Monterrey, Nuevo Leon

    Directory of Open Access Journals (Sweden)

    Prieto Gonzalez, Jose Manuel

    2016-03-01

    Full Text Available The current “Barrio Antiguo” (Old Quarter of Monterrey (Mexico, formerly known as "Cathedral Quarter", is a postmodern product arising from the intervention between 1988 and 1994 in a sector called First Square, shortly after the construction of the “Macroplaza” (1979-1985 destroyed a significant part of that same sector. Thus, “Barrio Antiguo” became an example of consciousness cleansing experience. The area is a part of what would become the center of Monterrey, whose physical and conceptual boundaries are still undefined. After a harsh period of degradation in the quarter, especially profound in the context of organized crime and its resulting violence in recent years, the Municipal Institute for Planning and Coexistence of Monterrey (IMPLANC has undertaken the task of regenerating the area. The aim of this lecture is to reveal the difficulties faced by the previously mentioned regeneration, starting with the "inferiority complex" that stirs up among the Monterrey population –traditionally-identified with the official discourse of "greatness"– due to the humility of both the architecture and the vernacular northeastern atmosphere of the quarter, especially when comparisons are made with national historic centers which are World Heritage Sites. El actual Barrio Antiguo de Monterrey, antaño conocido como “Barrio de Catedral”, es un producto posmoderno que surge de la intervención realizada entre 1988 y 1994 en un sector del llamado Primer Cuadro de la ciudad, poco después de que las obras de la Macroplaza (1979-85 destruyeran una parte importante de ese mismo sector. Barrio Antiguo vino a ser así una especie de lavado de conciencia. La zona es una parte de lo que sería el centro histórico de Monterrey, cuyos límites físicos y conceptuales aún están sin definir. Después de una dura etapa de degradación del Barrio, especialmente intensa en el contexto de la ola de violencia de los últimos años, el Instituto Municipal de Planeación y Convivencia de Monterrey (IMPLANC ha emprendido la tarea de regenerar la zona. El objetivo de este artículo es revelar las dificultades que enfrenta dicha regeneración, empezando por el “complejo de inferioridad” que suscita en una parte de la sociedad regiomontana –identificada tradicionalmente con el discurso oficial de “grandeza”– la humildad de la arquitectura y del ambiente vernáculo norestense de la zona, sobre todo cuando se establecen comparaciones con los centros históricos nacionales que son Patrimonio de la Humanidad.

    The first Ebola cases in West Africa were reported by the Guinea Ministry of Health on March 23, 2014, and by June it became the largest recorded Ebola outbreak. Centers for Disease Control and Prevention field teams were deployed to West Africa, including in-country logistics staff who were critical for ensuring the movement of staff, equipment, and supplies to locations where public health knowledge and experience were applied to meet mission-related requirements. The logistics role was critical to creating the support for epidemiologists, medical doctors, laboratory staff, and health communicators involved in health promotion activities to successfully respond to the epidemic, both in the capital cities and in remote villages. Logistics personnel worked to procure equipment, such as portable video projectors, and have health promotion materials printed. Logistics staff also coordinated delivery of communication and health promotion materials to the embassy and provided assistance with distribution to various partners. © 2015 Society for Public Health Education.

  19. ‘Benefactoria’ and the formation of feudal networks in tenth- to twelfth-century Leon and Castile

    Full Text Available This paper examines and evaluates the social networks that typified the feudal system. Using tenth- to twelfth-century documents, it explores the institution of benefactoria and the associated concepts of beneficium, servitium, prestimonium, and feudum in order to approach the subject of lordship: personal lordship at its most elementary, distinguished from other forms of power such as public jurisdiction or private property. Benefactoria and its associated concepts played a key role not only during the formative period of Leonese and Castilian lordship, but also in its subsequent development as a territorial institution. This paper argues that lordship, the definitive power-structure of the feudal system, was established and widely disseminated through the agreement of benefactoria pacts. These pacts, which enshrined the exchange of services for ‘protection’, were established between individuals and institutions that were socially unequal, and extended throughout free society, from the level of the king to that of the humblest peasants. In this sense, all free men were homines de benefactoria, linked together through private relationships of domination and submission, lordship and servitude: the inhabitants of properties that were specifically designated as behetrías simply represented a more partial and restrictive expression of the original concept of benefactoria. The pace and intensity of the processes that determined the formation and development of feudalism in León and Castile were marked by the spread of this type of social relationship, which was therefore both a defining factor and a catalyst within that system.
