    To determine the prevalence of the metabolic syndrome (SM) and its components in teenagers from the metropolitan area of Monterrey Nuevo Leon, Mexico (AMM). A transversal research involving 254 teenage students from 10 to 19 years old. To research investigated their personal characteristics, anthropometrics measures, glucose, triglycerides and cholesterol HDL. The SM definition was adapted from the one suggested by the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII). The SM prevalence was 9.4 % (IC95%: 5.8 to 13.0), there was not a difference between the sexes. The prevalence among each SM component was: 24.4% for high triglycerides, 20.1% for abdominal obesity, 19.0% for cholesterol of lipoproteins of a high density (HDL-c) low, 11.4 % for high glucose and for high blood pressure (9.1% diastolic and 5.9% systolic). The prevalent SM phenotypes were corporal mass (IMC) (OR = 4.93, IC95%: 2.26, 10.73) and the IMC interaction of the teenager with a family history of obesity (OR = 1.37, IC95%: 1.0, 1.87). It was observed that those with a family history of diabetes type 2 only experienced a marginal effect. The SM prevalence in teenagers from AMM is high it was an alarming situation if it continues into adulthood. The existence of obesity in relatives of the first and second grade, altogether with teenager IMC are important prediction factors of SM.

    Allergic reactions to insect bites are a global problem, the true incidence and prevalence of morbidity from adverse reactions to mosquito bites are unknown. To describe the adverse reactions to mosquito bites in school-age children of Monterrey, Nuevo Leon. A cross-sectional descriptive study was made via a randomized application of questionnaires to children from public elementary schools in the metropolitan area of Monterrey, Nuevo Leon. A total of 11 public schools randomly selected were included in the study. One thousand questionnaires were submitted, of which 506 fulfilled the inclusion criteria; 55% were females. Seventy-six percent referred adverse reactions to mosquito bites, itching (75%) and rash (72%) being the most frequent ones, in the last 12 months. Adverse reactions to mosquito bites occur frequently. Early detection is important to establish a prompt treatment.

    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.

    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.

    The concentration of pollen grains in the atmosphere over the metropolitan area of Monterrey, Nuevo Leon, Mexico, was analyzed throughout a year from March 2003-February 2004, focused on the genus Carya, Celtis, Cupressus, Fraxinus and Pinus owing to their interest as etiological pollinosis agents in diverse regions of the world. A 7-day Hirst type volumetric spore and pollen trap was located on a building roof of the city at 15 m from ground level for continuous sampling. The total quantity of pollen recorded for the study period was 21,083 grains/m(3), corresponding to 49.75 % of the taxa of interest. February and March were the months with higher pollen amounts in the air with 7,525 and 2,781 grains/m(3), respectively, and amounted to 49 % of total year through pollen. Fraxinus was the genus which contributed to the largest amount of pollen with 28 % of total grains (5,935 grains/m(3)) followed by Cupressus with 13 % (2,742 grains/ m(3)). Celtis, Pinus and Carya contributed with 5.3 % , 2.7 % , and 0.6 % of total pollen, respectively. These results indicate that Fraxinus and Cupressus are present in the area in sufficient quantity to indicate likely involvement in the origin of allergic disorders in the human population.

    Full Text Available The main aim of this study is to examine the behaviours during physical activity according with genre, age, and the level of education of the inhabitants of the municipality of Monterrey (Mexico. A transversal study is presented. The sample comprised 1, 008 individuals of 15 years old or older (498 male= 49.4% and 510 female= 50.6%. The rank of age was comprised between 15 and 87 years old (M=36.57; SD=17.05. To collect the data the technique of survey was used through an ad hoc questionnaire called «Physical-sport habits and life styles.» The results of the study revealed a proportion of sedentary subjects twice superior to those active subjects, that is, just a third part of the active population. The results revealed important differences between genre (p=.001, age groups (p=.000, and level of education (p=.000 in the three behaviours (active, abandonment, and never. Male, between 15 and 29 years old, and those with university education are those that presented higher percentages in the active behaviour. On the other hand, women, in the group of 45 to 59 years old, and those with high school completed are those that presented the highest rates of abandonment. Finally, women, in the group of 60 years old and older, and those subjects without education, or with elementary education, are those that to a greater extent never had performed physical-sport activity. These results can serve as a base for the designing of strategies that promote the adherence to exercise taking into consideration its own characteristics.

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

    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

    although systemic reactions resulting from hymenoptera stings have been studied extensively, the prevalence of allergic reactions to mosquitoes is unknown. to investigate the prevalence of allergic reactions to Aedes aegypti bites in patients seeking treatment at the Allergy and Clinical Immunology Regional Center of Jose E Gonzalez University Hospital in Monterrey, Mexico. we carried out a cross-sectional, descriptive study that included patients receiving skin tests for aeroallergens; skin sensitivity to mosquito bites was also tested. A questionnaire was used to obtain information about previous allergic reactions to mosquito bites. a total of 482 patients between 2 and 60 years of age were included; 53% were female, 407 (84.4%) had a history of local reactions to mosquito bites. Twelve patients (2.4%) stated a history of large local reaction; three (0.6%) of them with a positive skin prick test, one (0.2%) of those had systemic reaction history to mosquito. Eighty five (17.6%) patients had a positive mosquito skin test and 307 (63.6%) had a positive skin test for at least one aeroallergen. Seventy-eight (91.7%) of the 85 patients with a positive mosquito skin test had a history of local skin reactions to mosquito bite (odds ratio: 2.303 [confidence interval (CI) 1.037-5.10]. There was no statistically significance association between allergic diseases and mosquito allergy. adverse reactions and allergic reactions to mosquito bites occur frequently. However mosquito allergy is low. Further studies are required to determine the prevalence of mosquito allergy in the general population.

    Heart failure constantly increases its incidence and prevalence in our society, it was imperative to start a heart transplant program to improve the survival rates of patients with end stages of the disease. Legal issues made impossible to transplant patients out of Mexico City until recent years. Even with an acute hemodynamic and clinic improvement after the transplant, these patients frequently develop complications such as graft rejection or opportunistic infections due to the immunosuppressive schemes increasing the morbidity and mortality of the procedure. In the present article we report the experience acquired with 65 heart transplant patients from 4 transplant programs in Monterrey, Nuevo Leon, one of them from the socialized system and the other three from private hospitals. Our program not only has successfully transplanted patients with advanced age but, for the first time in Latin America we have transplanted patients assisted with the ambulatory Thoratec TLC II system. Even that we have faced obstacles like a newly started donation culture in our population and limited resources, our patient's survival rate push us to continue working with these very ill population.

    An ethnobotanical study in the Cumbres de Monterrey National Park (CMNP), Nuevo Leon, Mexico was conducted. In spite of the large area (1,773.7 km2), heterogeneous physiography, contrasting plant communities and high species diversity of the CMNP, very little was previously known about its useful plants. Based on 95 interviews with inhabitants of the region who were 35 years old or older, we recorded ethnobotanical data of 240 species (comprising 170 genera and 69 botanical families), and 146 different uses. Most of the cited uses (98) were found to be medicinal ones. Ninety five inhabitants 35 years old and oldest were interviewed to know what are the main plant uses in the Cumbres de Monterrey National Park. Two hundred and forty species, 170 genera, and 69 families of useful plants and 146 different uses were recorded. We found most of the uses to be medicinal (98), while the rest (48) represent various purposes. Herbaceous plants are the most used, followed by shrubs and trees.

    After a 10-year history of community health nursing research conducted by graduate students at the Universidad Autónoma de Nuevo León in Monterrey, Mexico, the faculty recognized a need to synthesize their work into a monograph. The purpose was to guide nursing practice, incorporate the findings into the body of nursing knowledge, and identify future research needs. Starting in 1994, three faculty members reviewed 29 theses written by community nursing majors from 1986 to 1993 to meet the requirements for the master's degree in nursing. They classified the studies according to their principal focus and synthesized the findings to derive common phenomena and themes. The endeavor resulted in a 40-page document and a proposed model in the form of an unpublished monograph.

    The reported prevalence of allergic systemic reactions to hymenoptera venom occur in up to 3.3% and large local reactions occur in 17% in the general population. To investigate the prevalence of hymenoptera sting allergy in a group of veterinary medicine students from Monterrey, Nuevo Leon, Mexico. A transverse and observational study was done with 64 students of veterinary medicine. We conducted a questionnaire about the students' history of insect allergy and atopy. Skin test with allergenic extracts of bee and ant were practiced to all subjects. We performed aeroallergen skin prick test to the subjets with suspected atopy. Students age ranged from 17 to 25 years (mean 20.2) and 37 were males. Twenty students (31.3%) had clinical history of atopy and positive skin tests to aeroallergens. On the other hand, 5 students (7.8%), including 2 atopic, had suffered large local reactions, but none of them had suffered systemic reactions. Bee and ant skin tests were positive in 15.6% and 31.3% of the students respectively. There was no difference in the prevalence of hymenoptera allergy between atopic and non atopic subjects (p < 0.05). Further, the frequency of atopy in subjects with positive skin tests for bee and ant was 50%. The prevalence of large local reactions and hymenoptera sensitization found in this group was similar to that found in other epidemiologic studies.

    A distributed hydrologic model can help bring consensus among diverse stakeholders in regional flood planning by producing quantifiable sets of alternative futures. This value is acute in areas with high uncertainties in hydrologic conditions and sparse observations. In this study, we conduct an application of the Triangulated Irregular Network (TIN)-based Real-time Integrated Basin Simulator (tRIBS) in the Santa Catarina basin of Nuevo Leon, Mexico, where Hurricane Alex in July 2010 led to catastrophic flooding of the capital city of Monterrey. Distributed model simulations utilize best-available information on the regional topography, land cover, and soils obtained from Mexican government agencies or analysis of remotely-sensed imagery from MODIS and ASTER. Furthermore, we developed meteorological forcing for the flood event based on multiple data sources, including three local gauge networks, satellite-based estimates from TRMM and PERSIANN, and the North American Land Data Assimilation System (NLDAS). Remotely-sensed data allowed us to quantify rainfall distributions in the upland, rural portions of the Santa Catarina that are sparsely populated and ungauged. Rural areas had significant contributions to the flood event and as a result were considered by stakeholders for flood control measures, including new reservoirs and upland vegetation management. Participatory modeling workshops with the stakeholders revealed a disconnect between urban and rural populations in regard to understanding the hydrologic conditions of the flood event and the effectiveness of existing and potential flood control measures. Despite these challenges, the use of the distributed flood forecasts developed within this participatory framework facilitated building consensus among diverse stakeholders and exploring alternative futures in the basin.

    To determine the prevalence of Trypanosoma cruzi in triatomines from Nuevo León using the standardization of an improved enzyme-linked immunosorbent assay test. From July to September 2005, 52 triatomines were captured in General Terán, a municipality located in Nuevo León. They were analyzed using optical microscopy (OM) and a polymerase chain reaction (PCR), as standards of reference, to develop a technique for detecting the parasite using enzyme-linked immunosorbent assay (ELISA). Using OM and PCR, 31 triatomines were found to be positive and 21 negative. Using ELISA, 27 samples were identified as positive and 25 negative (specificity 100%, sensitivity 87%, negative predictive value 84%, and positive predictive value 100%). The prevalence of infected triatomines was 59.61% with OM and PCR, and 51.92% with ELISA. Our data confirm that the ELISA assay in triatomines is a fast, reliable and useful tool. Since it was possible to simultaneously analyze a large number of samples with high sensibility and specificity values, the ELISA test proves to be useful for new epidemiologic studies having a high number of vectors. It is also less expensive than PCR. It is therefore recommended for epidemiological and preventive surveillance programs as a first screening test before conducting a confirmatory test using PCR.

    We studied serotypes circulating dengue virus (DENV) cases, entomological Breteau index, rain-fall index and epidemiology of groups affected during the 2010 outbreak in Nuevo Leon, Mexico. From 2,271 positive cases, 94% were dengue classic and 6% dengue hemorrhagic fever; DENV1 was mainly isolated (99%) (Central-American lineage of American-African-genotype). We found correlation between two environmental phenomena (Increment of rainfall and vector-indexes) (p ≤ 0.05) with epidemiological, clinical and risk of DENV-1 ongoing transmission.

    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.

    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 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.

    Some international organisations established maximum residue limits (MRLs) in food to protect human health. Mexico lacks regulations in this matter, affecting national and international trade from agroindustry. The aim of this study was to diagnose pesticide residues in oranges from Nuevo Leon, México, in citrus orchards. In May 2014, 100 orange fruit samples were taken randomly from orchards and subjected to analysis for 93 pesticides at residual level by GC/QQQ-MS and LCQ-TOF-MS. Results showed the presence of 15 pesticide residues in the samples. The comparison of the residual levels of pesticides found in orange samples among the MRLs allowed by USA, EU and Japanese regulations demonstrated that all samples were below MRLs issued by USA and Japan. Some orange samples were above MRLs issued by the EU. This provides a basis to establish strategies in order to satisfy International Standards to protect human health and encourage Food Safety in Mexico.

    The effects of alcohol on mortality due to motor vehicle accidents was studied. 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). 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. 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).

    Molecular detection of HEV in pig livers destined for human consumption in Nuevo Leon, Mexico. 87 livers were collected from pigs slaughtered in TIF and 40 livers from butchers. A 212 pb fragment of HEV ORF2 gene was amplified by semi-nested RT-PCR. 19.54% (17) of tif's and 22.5% (9) of butcher's livers were positive for HEV. Sequencing of the amplified products showed a 94%-95% homology with the sequences reported for genotype 3. Our results indicate that HEV is circulating in swine herds in the state, constituting a probable source of contamination of pig meat products.

    The effectiveness of spinosad and temephos for the control of mosquito larvae was evaluated in a tire dump in Allende, Nuevo Leon, Mexico. Three groups of 12 to 17 tires located in tree shade were utilized for this study. After the larvicides were applied, samples were collected weekly from 7 randomly chosen tires. The data showed a significant difference between the larvicides and control. Under the conditions of the present study, the effectiveness of spinosad against mosquito larvae was similar to that of temephos, both being effective for up to 91 days postapplication. In addition, spinosad allowed the establishment of the mosquito predator Toxorhynchites sp.

    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.

    Full Text Available El objetivo del trabajo consiste en estudiar la evolución del consumo agregado de energía eléctrica residencial en la Zona Metropolitana de Monterrey, Nuevo León, México. Ello, debido a que dicha metrópoli ha experimentado niveles de consumo muy por encima de la media nacional. En este sentido, la idea principal consiste en cuantificar el impacto generado por el crecimiento de los usuarios, la sensibilidad del consumo ante variaciones en el precio del servicio y de un indicador nacional de la actividad económica como medida proxy del ingreso de la zona ante la ausencia de un indicador regional. Para ello, se estima una función de demanda al estilo Cobb-Douglas con series de tiempo de 1993 al 2010 en frecuencia mensual y el enfoque de cointegración de Engel-Granger. Las estimaciones realizadas nos indican que un incremento porcentual del número de hogares incrementa en 0.61 por ciento el consumo. De la misma forma, un incremento porcentual el ingreso incrementa en 0.88 por ciento el consumo. En tanto que incrementos en el precio del servicio reducen la demanda en 0.63 por ciento en el largo plazo.

    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.

    Before 1996, solid organs from cadaveric donors (CD) did not account for more than 2% of all transplants. The need for more transplants led the state to undergo several legislative, societal, organizational, and infrastructure changes. A descriptive analysis of the evolution of the transplant program in the State of Nuevo León, Mexico, from 1996 to 2001. Trimester reports have been routinely performed since 1996 from the 14 institutions that are licensed to perform organ and tissue transplants in the State of Nuevo León, Mexico. All reports were concentrated and a descriptive analysis is presented herein. From 1996 until 2001, a total of 1457 organ and tissue (OT) transplants have been performed. At the end of this period, there was a 214% increase in the total number of transplants. By 2001, 73% of the program's total of 1457 OT transplants came from cadaveric donors. The state transplant program of Nuevo León has experienced a dramatic growth since 1996. The percent of organs transplanted from cadaveric donors is one of the highest in Mexico. There is still much work to be done at the state and national levels; better epidemiological studies and dialysis registries are needed as well as investment in transplant research.

    Nearly one-third of the world's population is infected with latent tuberculosis (LTBI). Tuberculosis (TB) rates in the border states are higher than national rates in both the US and Mexico, with the border accounting for 30% of total registered TB cases in both countries. However, LTBI rates in the general population in Mexican border states are unknown. In this region, LTBI is diagnosed using the tuberculin skin test (TST). New methods of detection more specific than TST have been developed, although there is currently no gold standard for LTBI detection. Our objective is to demonstrate utility of the Quantiferon TB gold In-Tube (QFT-GIT) test compared with the TST to detect LTBI among border populations. This is an observational, cross-sectional study carried out in border areas of the states of Nuevo Leon and Tamaulipas, Mexico. Participants (n = 210) provided a TST and blood sample for the QFT-GIT. Kappa coefficients assessed the agreement between TST and QFT-GIT. Participant characteristics were compared using Fisher exact tests. Thirty-eight percent of participants were diagnosed with LTBI by QFT-GIT. The proportion of LTBI detected using QFT-GIT was almost double [38% (79/210)] that found by TST [19% (39/210)] (P < 0.001). Concordance between TST and QFT-GIT was low (kappa = 0.37). We recommend further studies utilizing the QFT-GIT test to detect LTBI among border populations.

The questionnaire is a translation and adaptation to the questionnaire of 13 questions used to assess the knowledge about asthma among parents, according to the National Asthma Education Program of US. a total of 179 questionnaires were applied, in which 6 of the 13 questions were answered correctly by more than 90% of the teachers. The internal consistency reliability was adequate with a Cronbach a coefficient of 0.75. in order to obtain reliable data using questionnaires, these must undergo a validation process. Our questionnaire got validation because of the reliability shown according to the internal consistency analysis.

  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.

    To determine the distribution of Aedes albopictus (Skuse) in Nuevo Leon between 2001 and 2004. Standardized methods were used to collect 6371 samples of mosquito's larvae from 167 sites. The proportions of samples positive for Ae. albopictus were obtained by municipality and year, using the software program Excel. There were 1179 samples positive for Ae. albopictus. This species was distributed over 10 municipalities, as follows: Five on the Gulf of Mexico Coastal Plains, which predominantly have a semi-warm, sub-humid climate, and precipitations almost year round (Allende, Montemorelos, Linares, General Teran, and Santiago); two (Sabinas Hidalgo, and Cadereyta) localized on the North American Great Plains, which have a warm, semiarid climate, and scarce precipitations. The final three were Apodaca, San Nicolas, and Escobedo distributed over the metropolitan area of Monterrey City. Up to January 2004, the second most important epidemiological vector in the transmission cycle of Ae. albopictus worldwide was found in ten municipalities of Nuevo Leon State, Mexico.

    Full Text Available Introduction. About 500,000 species of fungi have been described to-date, although an estimated between 1 – 1.5 million species may occur. They have a wide distribution in nature, contributing to the decomposition of organic matter and playing a part in the biogeochemical cycles of major nutrients. A small number are considered pathogens of animals and plants. There is ample historical evidence that certain types of allergies are associated with fungi; exposure to fungal allergens occurs in both outdoor and indoor spaces. Many indoor allergens are the same as those found outside buildings, entering through windows and doors, ventilation systems, or through cracks or other fissures in the walls. Objective. To determine the diversity and abundance of fungal spores inside four churches in the metropolitan area of Monterrey city in Mexico. Materials and methods. The study was carried out from July 2009 – January 2010 using a Hirst type volumetric collector (Burkard Manufacturing Co Ltd. Results. A total of 31,629 spores from 54 taxa were registered in the four churches. The building that showed the highest amount of spores was the Santa Catarina Mártir Church with 12,766 spores, followed by Cristo Rey with 7,155 and Nuestra Señora del Roble with 6,887. Regularly high concentrations of spores were recorded from 14:00 – 20:00 hours. The highest concentration value was observed at the church of Santa Catarina Mártir at 16:00 hours with 1153 spores/m 3 air. Conclusions. The most abundant spores in the four churches studied corresponded to Cladosporium, the [i]Aspergillus/Penicillium complex[/i], [i]Coprinus[/i], [i]Ganoderma[/i], [i]Curvularia and Ustilago[/i].

    Good water quality of the Rio San Juan is critical for economic development of northeastern Mexico. However, water quality of the river has rapidly degraded during the last few decades. Societal concerns include indications of contamination problems and increased water diversions for agriculture, residential, and industrial water supplies. Eight sampling sites were selected along the river where water samples were collected monthly for 10 mo (October 1995-July 1996). The concentration of heavy metals and chemical constituents and measurements of bacteriological and physical parameters were determined on water samples. In addition, river discharge was recorded. Constituent concentrations in 18.7% of all samples exceeded at least one water quality standard. In particular, concentrations of fecal and total coliform bacteria, sulfate, detergent, dissolved solids, Al, Ba, Cr, Fe, and Cd, exceeded several water quality standards. Pollution showed spatial and temporal variations and trends. These variations were statistically explained by spatial and temporal changes of constituent inputs and discharge. Samples collected from the site upstream of El Cuchillo reservoir had large constituent concentrations when discharge was small; this reservoir supplies domestic and industrial water to the city of Monterrey.

    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.

    In the last 5 years, there has been only one reported human case of West Nile virus (WNV) disease in northern Mexico. To determine if the virus was still circulating in this region, equine and entomological surveillance for WNV was conducted in the state of Nuevo Leon in northern Mexico in 2006 and 2007. A total of 203 horses were serologically assayed for antibodies to WNV using an epitope-blocking enzyme-linked immunosorbent assay (bELISA). Seroprevalences for WNV in horses sampled in 2006 and 2007 were 26% and 45%, respectively. Mosquito collections in 2007 produced 7365 specimens representing 15 species. Culex mosquitoes were screened for WNV RNA and other genera (Mansonia, Anopheles, Aedes, Psorophora and Uranotaenia) were screened for flaviviruses using reverse-transcription (RT)-PCR. Two pools consisting of Culex spp. mosquitoes contained WNV RNA. Molecular species identification revealed that neither pool included Culex quinquefasciatus (Say) (Diptera:Culicidae) complex mosquitoes. No evidence of flaviviruses was found in the other mosquito genera examined. These data provide evidence that WNV is currently circulating in northern Mexico and that non-Cx. quinquefasciatus spp. mosquitoes may be participating in the WNV transmission cycle in this region.

    A method for estimating the general rate of nonpaternity in a population was validated using phenotype data on seven blood groups (A1A2BO, MNSs, Rh, Duffy, Lutheran, Kidd, and P) on 396 mother, child, and legal father trios from Nuevo León, Mexico. In all, 32 legal fathers were excluded as the possible father based on genetic exclusions at one or more loci (combined average exclusion probability of 0.694 for specific mother-child phenotype pairs). The maximum likelihood estimate of the general nonpaternity rate in the population was 0.118 +/- 0.020. The nonpaternity rates in Nuevo León were also seen to be inversely related with the socioeconomic status of the families, i.e., the highest in the low and the lowest in the high socioeconomic class. We further argue that with the moderately low (69.4%) power of exclusion for these seven blood group systems, the traditional critical values of paternity index (PI > or = 19) were not good indicators of true paternity, since a considerable fraction (307/364) of nonexcluded legal fathers had a paternity index below 19 based on the seven markers. Implications of these results in the context of genetic-epidemiological studies as well as for detection of true fathers for child-support adjudications are discussed, implying the need to employ a battery of genetic markers (possibly DNA-based tests) that yield a higher power of exclusion. We conclude that even though DNA markers are more informative, the probabilistic approach developed here would still be needed to estimate the true rate of nonpaternity in a population or to evaluate the precision of detecting true fathers.

    To estimate the prevalence of rheumatic diseases in rural and urban populations using the WHO-ILAR COPCORD questionnaire. We conducted a cross-sectional home survey in subjects > 18 years of age in the Mexican state of Nuevo Leon. Results were validated locally against physical examination in positive cases according to an operational definition by 2 rheumatologists. We used a random, balanced, and stratified sample by region of representative subjects. We surveyed 4713 individuals with a mean age of 43.6 years (SD 17.3); 55.9% were women and 87.1% were from urban areas. Excluding trauma, 1278 individuals (27.1%, 95% CI 25.8%-28.4%) reported musculoskeletal pain in the last 7 days; the prevalence of this variable was almost twice as frequent in women (33% vs 17% in men); 529 (11.2%) had pain associated with trauma. The global prevalence of pain was 38.3%. Mean pain score was 2.4 (SD 3.4) on a pain scale of 0-10. Most subjects classified as positive according to case definition (99%) were evaluated by a rheumatologist. Main diagnoses were osteoarthritis in 17.3% (95% CI 16.2-18.4), back pain in 9.8% (95% CI 9.0-10.7), undifferentiated arthritis in 2.4% (95% CI 2.0-2.9), rheumatoid arthritis in 0.4% (95% CI 0.2-0.6), fibromyalgia in 0.8% (95% CI 0.6-1.1), and gout in 0.3% (95% CI 0.1-0.5). This is the first regional COPCORD study in Mexico performed with a systematic sampling, showing a high prevalence of pain. COPCORD is a useful tool for the early detection of rheumatic diseases as well as for accurately referring patients to different medical care centers and to reduce underreporting of rheumatic diseases.

    A first survey of elemental contents in airborne particulate matter from Monterrey, Nuevo Leon, Mexico, was performed using PIXE. This second largest industrial city is located 715 km north of Mexico City, and counts with a population of nearly three million inhabitants in its conurbation. Air pollution in the place comes from a great variety of industries ranging from iron smelters to furniture manufacturing, as well as from fuel combustion in vehicles and industries. This study presents results of elemental contents in airborne particulate matter in two particle size fractions: PM 2.5 and PM 15 . The samples were collected during five weeks on working days, Monday-Friday, from 9 December 1996 to 14 January 1997. Two samples a day were collected, 12 h each, night-time and day-time. These first results show local pollution as typical from a large urban area in conjunction with an active industry. Thirteen elements were consistently detected in most of the samples and some episodes due to both industrial and human activities were identified. A general discussion about the results obtained is presented

    Definition of asthma has radically changed in the last few years. It has been given great importance to the its inflammatory component that can become irreversible. It is not clear yet the cause of the increase in prevalence and mortality of asthma observed in developed countries despite an increase in the number and efficacy of the therapeutic resources. There is still much to do on studying of the statistics on prevalence and mortality rate of the undeveloped countries. In Latin America, asthma prevalence, in 1983 was reported in 3.5% in seven countries. We reviewed the death certificates in the state of Nuevo León, México, in the 1980's decade, and compared the total death rate with those attributed to asthma, according to the diagnostics criteria code 493 from the International Classification of Diseases. We also reviewed the clinical records of patients admitted to a general hospital (University Hospital of Monterrey, Nuevo Leon, Mexico) as well as the autopsy reports from the same time period. General mortality rate, as well as the mortality rate due to respiratory diseases (asthma, emphysema, chronic bronchitis and others) was unchanged (5.5 x 100,000 people), despite an increase of 100% in the size of the population. Asthma prevalence has increased from 1.2% in 1979 to 2.5% in 1989 (approximately 75,000 cases). From the 1,114 autopsies done in the University Hospital in the 1980's decade, none could be attributed to an asthma death. It is mandatory that other states in this country report parallel studies to ours, so we can have reliable data on prevalence and mortality rates of asthma. In doing so, we can learn the distribution and consequences of this disease.

    Full Text Available Mexico has a rich tradition in medicinal plant use within its diverse traditional healing practices. Many people have used medicinal herbs to treat a variety of diseases and ailments for many generations. Located in the northeast, Monterrey is Mexico’s third largest city and one of the most industrialized cities in Latin America. In spite of widespread use of modern pharmaceuticals, and the availability of "scientific" or mainstream medicine in this city, many people still rely on traditional healers, as well as the use medicinal plants to combat illness. This study was undertaken in order to obtain information regarding the most popular medicinal plants used in Monterrey, as well as their uses, forms of application, and origin. Thirteen herbal providers voluntarily accepted to be interviewed within 2 of the city’s largest popular herbal marketplaces. A questionnaire written in the Spanish language was provided to all interviewees, regarding their years in business, their source of information or expertise in recommending herbs, as well as the type of herbs employed for the treatment of various diseases or afflictions. Fifty-six medicinal plants belonging to 27 botanical families, mostly sold as crude herbs, were mentioned by the herbal providers as being the most commonly used to treat various ailments.

    Full Text Available Of the 10 awards given every year by the Prestressed Concrete Institute for the most outstanding prestressed concrete projects, two have been awarded in California this year, one of them to the Willow Creek bridge, near Monterrey. The prestressed, double T girders of this bridge were made at a workshop, a great distance from the bridge site. These are 24 m long, 1.35 m high, and are stabilized by transversal diaphragms, 20 cm in thickness. The table deck is of reinforced concrete, being 8.85 m wide and 20 cm thick. The structure is straightforward, slender, and adapts itself pleasantly to the background. It has seven spans and crosses over a secondary road, in addition to bridging the Willow stream. The supporting piles are hollow, of rectangular cross section, and over them a cross beam carries the five girders and the deck itself. The end abutments consist of vertical reinforced concrete walls, and supporting, soil filled, structures. The above information was supplied by the California Road Department.De los diez premios que anualmente concede el Prestressed Concrete Institute para las obras de hormigón pretensado más notables, dos han correspondido a California y uno de ellos al puente de Willow Creek, situado en la región de Monterrey. Las vigas de hormigón pretensado, con sección en forma de doble T, se prefabricaron en un taller situado a gran distancia del puente. Tienen 24 m de longitud y 1,35 m de canto, estando arriostradas con diafragmas transversales de 20 cm de espesor. La losa del tablero, de hormigón armado, tiene 8,85 m de anchura y 20 cm de espesor. La estructura es sencilla, esbelta y armoniza perfectamente con el paisaje que la circunda. Tiene siete tramos y salva un paso inferior secundario y el arroyo Willow. Los soportes, se apoyan sobre pilotes, algunos de gran altura; son huecos, de sección rectangular y terminan en una cruceta que sirve de sostén a las cinco vigas que soportan la losa del tablero.

    The presence of Cryptococcus spp. has been reported in Mexico's capital city; however, to our knowledge there are no reports of its presence in the state of Nuevo León located in northeast Mexico. This is presumed to be because the hot and dry climate in this region does not favor cryptococcal proliferation. This study confirmed the presence of C. neoformans and C. albidus in 20% (10/50) of randomly selected fecal samples of pigeons (Columba livia) in the Monterrey metropolitan area. The presence of this yeast in the state of Nuevo León is proof of its adaptation to the typically hot climate of the area and is consistent with recent reviews of cryptococcosis cases in several local hospitals. The two species were identified and characterized through microbiological tests and molecular identification by DNA extraction and PCR amplification of highly conserved 18S ribosomal DNA using ITS1 and ITS2 as target regions. The PCR products were sequenced and compared with those reported in GenBank.

    The serological prevalence of Q fever in Mexico is unknown. A serological survey for Coxiella burnetii was undertaken on a randomly selected population of dairy cattle, beef cattle, goats and sheep flocks. Serological examination of animal sera for antibodies against Coxiella burnetii was carried out by the ELISA technique. The 28% of the dairy cattle and 10% of beef cattle examinated were antibody positive. Sera from goats and sheep also had antibodies against this rickettsia, 35% and 40% respectively.

    Heart failure is one of the most important causes of death worldwide. Heart transplant is the last effective alternative when the medical and surgical treatments have failed in patients with end stage heart failure, giving them an 80% one year survival rate. Unfortunately, during the outcome, the heart transplant patients can develop complications such as graft rejection and opportunistic infections because of the use of immunosuppressive therapy. In the present article we report the experience with 33 heart transplant patients. Our program not only has successfully transplanted patients with advanced age but, for the first time in Latin America we have transplanted patients assisted with the ambulatory Thoratec TLC II system. Even with limited resources, we have managed the same complications than other heart transplant programs, our 82% one year survival rate is similar than reports in medical literature.

    Drug-resistant tuberculosis (DRTB) is steadily increasing in Mexico, but little is known of patient risk factors in the Mexico-United States border region. This preliminary case-control study included 95 patients with active pulmonary TB with drug susceptibility results attending the José E. González University Hospital in the urban hub of Nuevo León-the Monterrey Metropolitan Area. We report potential social and clinical risk factors of DRTB among this hospital-based sample. We collected data through face-to-face interviews and medical record reviews from 25 cases with DRTB and 70 drug-sensitive controls. DNA was collected to assess an effect of genetic ancestry on DRTB by using a panel of 291,917 genomic markers. We calculated crude and multivariate logistic regression. After adjusting for potential confounding factors, we found that prior TB treatment (odds ratio, 4.5; 95% confidence interval, 0.9-21.1) and use of crack cocaine (odds ratio, 4.6; 95% confidence interval, 1.1-18.7) were associated with DRTB. No other variables, including genetic ancestry and comorbidities, were predictive. Health care providers may benefit from recognizing predictors of DRTB in regions where routine drug susceptibility testing is limited. Prior TB treatment and illicit drug use, specifically crack cocaine, may be important risk factors for DRTB in this region. Copyright © 2014 Elsevier Inc. All rights reserved.

    The authors' aim was to isolate and identify bacteria or yeast that may be present on the surface of 20-peso banknotes from the metropolitan area of Monterrey, Mexico. They randomly studied a total of 70 20-peso banknotes for the presence of bacteria and species of Candida by conventional methods. Out of the 70 banknotes, 48 (69%) were found to be contaminated. The most prevalent species observed was Candida kruseii (19 bills, 27%) followed by Burkholderia cepacia (9 bills, 13%); 22 (31%) bills showed no growth. Of the 48 contaminated bills, four (5.7%) yielded bacteria considered pathogenic and the other 44 bills (63%) yielded bacteria considered potentially pathogenic. Eleven bills showed more than one microbial species. The results of the authors' study show that contamination occurs on paper currency in the metropolitan area of Monterrey. The authors' findings provide evidence that currency banknotes may represent a threat to human health.

De ellos se dice que son organismos obreros sometidos a la voluntad de los patrones, que los crean y dirigen. En México, esta clase de sindicatos eran hasta hace poco un fenómeno regional, restringido a la ciudad de Monterrey, donde han tenido su mayor desarrollo. Sin embargo, coincidiendo con la crisis y reorganización del sindicalismo mexicano y la apertura del sistema político nacional, han crecido en número e influencia política.

Con el propósito de saber si éste se efectúa de forma tal que los individuos pudieran estar considerando su impacto sobre el medio ambiente. Metodología: se efectuó una encuesta a 613 personas del lugar y los resultados fueron analizados con métodos estadísticos. Resultados: se encontró que aunque la gente señala conocer conceptos relacionados a la sostenibilidad, le dan poca importancia al perjuicio que su demanda de bienes y servicios causa al medio ambiente. Limitaciones: por cuestiones presupuestarias, haber realizado un muestreo que aunque representativo no fue aleatorio. Conclusiones: aunque los individuos en su mayoría señalan conocer conceptos relacionados a la sostenibilidad, podemos advertir que más que razonados estos son intuitivos y, en general, aleccionados desde los medios de comunicación.

Hablamos del Nuevo Mundo en la medida que aceptamos, por una parte, la concepción del nuevo espacio generado a partir del encuentro de dos culturas, la precolombina americana y la propiamente europea llegada principalmente a través de España, y, por otra parte, aceptando también que el nuevo continente resulta ser la pieza clave que ayuda definitivamente a configurar un nuevo cosmos que revela al mundo su otro extremo y aquella parte que manifiesta la totalidad en la certeza de que la tierra es un planeta.

  14. Obituary: Leon Van Speybroeck, 1935-2002

    Science.gov (United States)

    Gorenstein, Paul; Tananbaum, Harvey Dale

    2003-12-01

    Leon Van Speybroeck, a master designer of X-ray telescope mirrors and the telescope scientist for the Chandra X-ray Observatory, died in Newton, Massachusetts, on 25 December 2002, shortly after learning that he had metastatic melanoma. Leon was born on 27 August 1935 in Wichita, Kansas. His father, Paul, was Assistant Treasurer and head of the accounting department at Beech Aircraft, and his mother, Anna Florence (Utley), was a homemaker. Both parents died in 1996. Leon's younger sister, Saundra, is a nurse and his younger brother, John, is a surgeon. Leon received a BS in 1957 and a PhD in 1965, both in physics, from MIT. His PhD thesis, ``Elastic Electron-Deuteron Scattering at High Momentum Transfer," was carried out under the supervision of Henry Kendall and Jerome Friedman. Leon spent two more years at MIT as a research associate. In 1967, he was hired by American Science and Engineering (AS&E) in Cambridge, Massachusetts, and joined the X-ray astronomy group led by Riccardo Giacconi, who received the 2002 Nobel Prize in Physics for contributions to astrophysics that led to the discovery of cosmic X-ray sources. Leon soon became involved in the design and construction of high-resolution, grazing-incidence X-ray telescopes, starting with the Apollo Telescope Mount flown on NASA's Skylab from 1973 to 1974. A series of high-resolution X-ray images of the solar corona led to dramatic changes in ideas about the solar corona, with new emphasis on magnetic dynamo processes. When the Smithsonian Astrophysical Observatory and the Harvard College Observatory morphed into the Harvard-Smithsonian Center for Astrophysics (CfA) in 1973, Leon, with Giacconi and other senior X-ray astronomers from AS&E, joined the CfA and formed the high-energy astrophysics division. Leon guided the design and development of the X-ray mirrors on NASA's Einstein Observatory, which was flown from 1978 to 1981 as the first cosmic X-ray observatory with an imaging telescope. Along the way, he

    2014-12-01

    Full Text Available In this paper, an attempt has been made to analyse how the violence and abuse against elderly migrants in Monterrey, Mexico affects their health. For this research, 257 elderly Mexican migrants were surveyed in the Metropolitan Area of Monterrey during 2012 through 2013. The study found that the majority of elderly people migrate to urban areas in search of a better economic opportunity. Once in the city, they are absorbed into the informal economic sectors. Results indicate that most of these elderly people suffer physical, sexual and psychological violence, as well as neglect and financial abuse from their employer, relatives, clients and pedestrians, which has an adverse effect on their health. Elderly migrants reported numerous health problems, where many of them were suffering from different types of injuries, stress and depression, among others. This paper concluded that violence suffered by elderly migrants has a significant impact on their health.

  16. Social segregation of indigenous migrants in Mexico: An overview from Monterrey

    2012-01-01

    Full Text Available In Mexico, rural to urban migration is a clearly noticeable phenomenon. During the last few years, there has been spontaneous growth in the migration of indigenous people towards the northern cities of Mexico, especially to Monterrey, in search of employment. Once the migrants arrive in this metropolis, they face difficulties adjusting and adapting to the city environment because of hidden discrimination. The main argument and hypothesis of this paper is that indigenous people isolate themselves and segregate themselves socially due to fear of (cultural and racial discrimination and violence. For this study, data were obtained from fieldwork carried out during 2009 and 2010 in Monterrey, Mexico, where we interviewed 350 indigenous people that had moved there from different parts of the country.

    Partida A, M.A.

    1977-01-01

    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.

    Severe fungal infections, particularly those caused by Candida spp, have increased in recent decades and are associated with an extremely high rate of morbidity and mortality. Since plants are an important source of potentially bioactive compounds, in this work the antifungal activity of the methanol extracts of 10 plants (Acacia rigidula, Buddleja cordata, Cephalanthus occidentalis, Juglans nigra, Parkinsonia aculeata, Parthenium hysterophorus, Quercus canbyi, Ricinus communis, Salvia coccinea and Teucrium bicolor) were evaluated. The activity was evaluated according to the micro dilution assay described in CLSI M27-A protocol using some clinical isolates of different species of Candida (C. albicans, C. parapsilosis, C. tropicalis, C. krusei and C. glabrata). All extracts showed MIC values < 31.25μg/mL against at least one of the strains used, which is very interesting because it was crude extracts. Acacia rigidula (0.93-3.75μg/mL) and Quercus canbyi (0.93-7.5μg/mL) had antifungal activity against 7 strains with MIC values <8μg/mL in all cases. Furthermore excerpts activity against Mycobacterium tuberculosis (strain H37rv) was evaluated. Only Salvia coccinea and Teucrium bicolor showed MIC values125μg/mL by the method of MABA.

    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)

    1994-12-31

    This paper presents here the results of a survey conducted in summer 1992 at Guadalajara and Monterrey homes. The survey main objective was to examine the potential of the replacement of incandescent bulbs for fluorescent compact bulbs (FCBs) to save electricity. Additionally it was determined the saturation level of other electric home appliances. Considering the physical restrictions of lanterns, during the evening demand peak hours a maximum of about 3.6 million of FCBs can be introduced into the electric network between 8:00 and 9:00 Pm, economizing about 207 MW. It was found that the importance of lighting, the potential of FCBs and the equipment with electric home appliances varies significantly in accordance with the electricity consumption at home. Lighting represents at least about 22% and 14% of the total electricity consumption in the homes of Guadalajara and Monterrey, respectively. This percentage is higher among low electricity consumption users. The saturation in electrical home appliances demonstrated the importance of the refrigerators, TV sets, and air conditioning units (these ones only for Monterrey). In both cities about 1.5 TV sets and 0.96 refrigerators per home were reported. In Monterrey 0.4 air conditioning units and 1.6 electric fans per home were reported. In Guadalajara only about 0.5 fans per home were reported. The results of this survey show the importance of promoting programs to increase the energy efficiency to cover the lighting and refrigeration needs in both cities and air conditioning in Monterrey.

    The ongoing outbreak of Ebola Virus Disease in West Africa requires immediate and sustained input from the international community in order to curb transmission. The CDC has produced a model that indicates that to end the outbreak by pushing the reproductive number below one, 25% of the patients must be placed in an Ebola Treatment Unit (ETC) and 45% must be isolated in community settings in which risk of disease transmission is reduced and safe burials are provided. In order to provide firmer targets for the international response in Sierra Leone, we estimated the national and international personnel and treatment capacity that may be required to reach these percentages. We developed a compartmental SEIR model that was fitted to WHO data and local data allowing the reproductive number to change every 8 weeks to forecast the progression of the EVD epidemic in Sierra Leone. We used the previously estimated 2.5x correction factor estimated by the CDC to correct for underreporting. Number of personnel required to provide treatment for the predicted number of cases was estimated using UNMEER and UN OCHA requests for resources required to meet the CDC target of 70% isolation. As of today (2014-12-04), we estimate that there are 810 (95% CI=646 to 973) EVD active cases in treatment, with an additional 3751 (95% CI=2778 to 4723) EVD cases unreported and untreated. To reach the CDC targets today, we need 1140 (95% CI=894 to 1387) cases in ETCs and 2052 (95% CI=1608 to 2496) at home or in a community setting with a reduced risk for disease transmission. In 28 days (2015-01-01), we will need 1309 (95% CI=804 to 1814) EVD cases in ETCs and 2356 (95% CI=1447 to 3266) EVD cases at reduced risk of transmission. If the current transmission rate is not reduced, up to 3183 personnel in total will be required in 56 days (2015-01-29) to operate ETCs according to our model. The current outbreak will require massive input from the international community in order to curb the

    Full Text Available This paper analyses the ideological discourse of the local print and television news media of the eighties in the city of Monterrey, Mexico according to the biographical narratives of four leading journalists. The purpose is to pay attention to the role of ideology in the media as emphasized by cultural studies in its beginnings. The main question posed was: What was the role of the media in the eighties in the reproduction of the ideology of the economic and industrial elite of Monterrey and its relationship with the value system and civic identity of the audience members? According to the journalists interviewed, members of the industrial elite had a direct and explicit influence in the policies and contents of the main local newspapers and television stations, except for a daily newspaper that lost its predominance when rejecting that influence. The paper discusses the close relationship between media, audiences and the structures of ideological reproduction of the local industrial group, and the ways in which all these elements continously interact.

    This study explored relationships between several hypothesized dimensions of gender identity and substance use outcomes within a non-probability sample of adolescents in Monterrey, Mexico. Based on Mexican concepts of machismo and marianismo, four gender identity constructs were measured: aggressive masculinity, assertive masculinity, affective femininity and submissive femininity. The study assessed how well these gender identity measures predicted substance use behaviors, substance use intentions, expectancies, and normative approval, and exposure and vulnerability to substance offers. Data were drawn from questionnaires completed by 327 students from 2 Monterrey secondary schools. Multivariate ordered logistic and linear regression analyses, adjusted for school level effects, indicated that aggressive masculinity was associated with higher risk of drug use on most outcomes, while affective femininity was associated with lower risk on selected outcomes. Assertive masculinity was associated with only one of the outcomes examined and submissive femininity with none of them. Most gender identity effects persisted after controlling for biological sex, academic performance, age, and other gender identity measures. For two of the outcomes, the gender identity measures had significantly stronger effects for males than for females. The findings are interpreted in light of males' higher risk for drug use and changes in gender roles and gendered behavior that are now occurring in Mexico as in the U.S.

    Full Text Available Značilen pojav, ki ga lahko opazimo v Mehiki, je ruralno urbana migracija oziroma preseljevanje ljudi s podeželja v mesta. Zadnjih nekaj let se stopnja preseljevanja avtohtonih prebivalcev v mesta na severu Mehike, še zlasti v Monterrey, kjer iščejo zaposlitev, nenadzorovano veča. Ko migranti prispejo v to velemesto, imajo zaradi prikrite diskriminacije težave s prilagajanjem mestnemu okolju. Glavni argument in hipoteza tega članka je, da se ti ljudje sami družbeno izolirajo in segregirajo, ker se bojijo (kulturne in rasne diskriminacije in nasilja. Podatke za to študijo smo zbrali s pomočjo terenske raziskave, za katero smo leta 2009 in 2010 v Monterreyu intervjuvali 350 avtohtonih prebivalcev, ki so se tja priselili iz različnih krajev v Mehiki.

    Full Text Available The aim of this paper is to describe the reasons that have given origin to the amotivation of Monterrey adult citizens that have not done any physical activity according to gender, age and the level of studies. The sample was estimated in 1,118 subjects to obtain result validity with an error range of ±3% and a reliability level of 95.5%. The sample procedure used has been multistage with a proportional affixation, resorting to two types of stratificated random sampling by conglomerates. Results reveal that the values beliefs were the ones generating the amotivation to never have practiced any physical activity on leisure time of the subjects from 30 to 44 years old with high school finished

    Full Text Available This paper tries to explore the process of urbanization and spatial changes in demographic features in the Monterrey Metropolitan Region (MMR, Mexico. This city is the third largest urban sector in Mexico which has around 4 million population. It is also the industrial and economic capital of the country. The present study found that rapid urbanization in the metropolitan region has a close association with process of industrialization. In population distribution and composition, study found that the metropolitan region had its “demographic transition” during the years seventies and currently the region is taking advantages of demographic bonus cohort, i.e. a higher concentration of population in economic active groups compare to children and old age population. However, this paper indentified a higher imbalance in metropolitan demographic scenario. On the one hand, there is di-populization in the city center region and in other there is a steady increment of population in peri-urban region.

    Recent rapid advances in web technologies and cloud computing show great promise for facilitating collaboration and transparency in water planning efforts. Water resources planning is increasingly in the context of a rapidly urbanizing world, particularly in developing countries. In such countries with democratic traditions, the degree of transparency and collaboration in water planning can mean the difference between success and failure of water planning efforts. This is exemplified in the city of Monterrey, Mexico, where an effort to build a new long-distance aqueduct to increase water supply to the city dramatically failed due to lack of transparency and top-down planning. To help address, we used a new, web-based water system modeling platform, called OpenAgua, to develop a prototype decision support system for water planning in Monterrey. OpenAgua is designed to promote transparency and collaboration, as well as provide strong, cloud-based, water system modeling capabilities. We developed and assessed five water management options intended to increase water supply yield and/or reliability, a dominant water management concern in Latin America generally: 1) a new long-distance source (the previously-rejected project), 2) a new nearby reservoir, 3) expansion/re-operation of an existing major canal, 4) desalination, and 5) industrial water reuse. Using the integrated modeling and analytic capabilities of OpenAgua, and some customization, we assessed the performance of these options for water supply yield and reliability to help identify the most promising ones. In presenting this assessment, we demonstrate the viability of using online, cloud-based modeling systems for improving transparency and collaboration in decision making, reducing the gap between citizens, policy makers and water managers, and future directions.

    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.

    Full Text Available En México, un fenómeno notable es la migración del campo a la ciudad. En los últimos años se ha dado un crecimiento en el número de migrantes indígenas hacia las ciudades del norte del país, específicamente a la Zona Metropolitana de Monterrey (ZMM en busca de empleo. Al llegar a esta metrópoli, los migrantes tienen problemas para adaptarse e integrarse en el ámbito urbano de esta sociedad, fundamentalmente por la oculta discriminación existente hacia los indígenas, por lo cual, muchos de ellos llegan a sufrir problemas sociales, psicológicos y personales, que provocan el retorno de algunos a sus lugares de origen o el cambio de residencia. En este sentido, en el presente artículo se ha investigado la importancia de la migración indígena hacia la Zona Metropolitana de Monterrey y sus procesos de integración y adaptación. El análisis se basó en los resultados de una encuesta aplicada a estos migrantes en los primeros meses del 2008 en esta zona urbana.

    Developing a surveillance system during a public health emergency is always challenging but is especially so in countries with limited public health infrastructure. Surveillance for Ebola virus disease (Ebola) in the West African countries heavily affected by Ebola (Guinea, Liberia, and Sierra Leone) faced numerous impediments, including insufficient numbers of trained staff, community reticence to report cases and contacts, limited information technology resources, limited telephone and Internet service, and overwhelming numbers of infected persons. Through the work of CDC and numerous partners, including the countries' ministries of health, the World Health Organization, and other government and nongovernment organizations, functional Ebola surveillance was established and maintained in these countries. CDC staff were heavily involved in implementing case-based surveillance systems, sustaining case surveillance and contact tracing, and interpreting surveillance data. In addition to helping the ministries of health and other partners understand and manage the epidemic, CDC's activities strengthened epidemiologic and data management capacity to improve routine surveillance in the countries affected, even after the Ebola epidemic ended, and enhanced local capacity to respond quickly to future public health emergencies. However, the many obstacles overcome during development of these Ebola surveillance systems highlight the need to have strong public health, surveillance, and information technology infrastructure in place before a public health emergency occurs. Intense, long-term focus on strengthening public health surveillance systems in developing countries, as described in the Global Health Security Agenda, is needed.The activities summarized in this report would not have been possible without collaboration with many U.S and international partners (http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/partners.html).

    Environmental pollution may severely impact reptile species in urbanized areas. The magnitude of the impact is analyzed in the present study using lizard tail tips for the quantitative evaluation of enzymatic biomarkers of pollution. Spiny lizards (Sceloporus serrifer and S. torquatus) were collected from two suburban localities in the Monterrey metropolitan area, Mexico: Chipinque Ecological Park, a natural protected area, and El Carmen Industrial Park (IP), a highly polluted site. Different enzymes were used as biomarkers including: acetylcholinesterase (AChE), butyrylcholinesterase (BChE), carboxylesterase (CaE), alkaline phosphatase (ALP), acid phosphatase (ACP), superoxide dismutase (SOD) and glutathione S-transferase (GST). The levels of AChE, BChE and ACP activity were not significantly different between localities. AChE and BChE, commonly used as biomarkers of neurotoxic polluting agents (e.g. organophosphate pesticides) do not appear to be affecting the populations from the study locations. In contrast, the levels of CaE, GST, ALP and SOD were significantly different between the localities. These biomarkers are regularly associated with oxidative stress and processes of detoxification, and generally indicate pollution caused by heavy metals or hydrocarbons, which are common in industrial sites. The data resulting from the analysis of these biomarkers indicate that these polluting agents are affecting the populations of Sceloporus in IP. The present work validates the possibility of conducting additional ecotoxicological studies using biomarkers in combination with a nondestructive sampling technique in species of spiny lizards that are abundant in many North America areas.

En principio, los datos sugieren un panorama de alta dependencia económica y social de esta población derivado de ingresos y condiciones de salud precarias. Por un lado, se observó que el sistema institucional facilitó principalmente el acceso a servicios de salud y pensiones, aunque la cobertura de este último servicio fue más restringida y diferenciada.

When the violent civil conflict in Sierra Leone (1991 to 2002 ended, an international consortium assisted in restoration of the LF program at Kenema Government Hospital (KGH in an area with the world's highest incidence of the disease.Clinical and laboratory records of patients presenting to the KGH Lassa Ward in the post-conflict period were organized electronically. Recombinant antigen-based LF immunoassays were used to assess LASV antigenemia and LASV-specific antibodies in patients who met criteria for suspected LF. KGH has been reestablished as a center for LF treatment and research, with over 500 suspected cases now presenting yearly. Higher case fatality rates (CFRs in LF patients were observed compared to studies conducted prior to the civil conflict. Different criteria for defining LF stages and differences in sensitivity of assays likely account for these differences. The highest incidence of LF in Sierra Leone was observed during the dry season. LF cases were observed in ten of Sierra Leone's thirteen districts, with numerous cases from outside the traditional endemic zone. Deaths in patients presenting with LASV antigenemia were skewed towards individuals less than 29 years of age. Women self-reporting as pregnant were significantly overrepresented among LASV antigenemic patients. The CFR of ribavirin-treated patients presenting early in acute infection was lower than in untreated subjects.Lassa fever remains a major public health threat in Sierra Leone. Outreach activities should expand because LF may be more widespread in Sierra Leone than previously recognized. Enhanced case finding to ensure rapid diagnosis and treatment is imperative to reduce mortality. Even with ribavirin treatment, there was a high rate of fatalities underscoring the need to develop more effective and/or supplemental treatments for

    To assess placental transfer of antibodies to the child at birth and at 2 months of age. For the quantification of anti-PT IgG antibodies, we used an indirect enzyme-linked immunosorbent assay standardized by The National Institute of Epidemiologic Diagnosis and Reference (InDRE). Samples were considered negative from 0 to 48 IU/mL, indeterminate from 49 to 93 IU/mL and positive at ≥94 IU/mL. We performed a cross-sectional assessment of anti-PT IgG antibody levels in the mother, umbilical cord, and child. There was a higher concentration of IgG anti-TP in the umbilical cord (4.3%) and in the mother (1.4%), but a total absence was observed in the child (0%). The vulnerability of children to Bordetella pertussis shows the need to implement effective immunization strategies, whether actively, in the child, or passively through the mother, adolescents, and adults who are in contact with the child.

    Sensitization to allergens in atopic dermatitis patients is a risk factor for developing asthma and allergic rhinitis in the future,as well as an aggravating factor in the course of the disease. Recent studies have attributed the activity of the proteases of some antigens to cause a grater defect in the epithelial barrier and a more severe disease. To know the sensitization to allergens pattern in children with atopic dermatitis attended at Allergology Service of University Hospital of UANL, Mexico, and to know if these children have higher sensitization to antigens with proteolytic activity. A retrospective study was done reviewing the skin prick test reports done in our service to children ranging from 5 months to 16 years old, diagnosed with atopic dermatitis during a period of 2 years, from January 2012 to January 2014. The frequency of sensitization to aeroallergens and food were analyzed as well as the weal size (≥6mm) on the skin in response to each particular allergen in the case of food skin prick test. Reports of skin tests of 66 children, 30 boys and 36 girls, were included; 37 of children were sensitized to more than one allergen,18/66 had asthma and/or allergic rhinitis, 40/66 60% skin prick tests were positive to high activity protease aeroallergens (Dermatophagoides pteronyssinus/Dermatophagoides farinae). Regarding food, sensitization was seen in 38 children; fruits and vegetables were the two most common foods. Only seven children had skin prick weal bigger than 6 mm, mainly to egg, fish and cow's milk. Children with atopic dermatitis are often sensitized to high protease activity aeroallergens, polysensitization is very common and the association with airway allergy is seen early in life. Sensitization to food is also common in these patients, but only a small percentage showed a response large enough to be associated with disease severity.

    In 1980 Smithells et al. reported that the intake of folic acid (FA) prevents the recurrence of neural tube defects (NTDs) [1]. After this and several other studies were conducted, the intake of 400 micrograms of folic acid per day, at least three months before and three months during pregnancy for prevention of NTD, was proposed [2,3,4]. Other strategies were also developed to increase folate blood levels in woman of childbearing age such as promoting the consumption of folate rich foods and food fortification (flour and most recently rice) [5]. Nevertheless, results have not been as expected due to poor consumption of folic acid supplements [6]. As a result, in the year 2000, a novel strategy was developed in order to increase folate blood levels in Mexican women. The results of the strategy are presented, as well as, a discussion about how to personalize a program for different populations.

    Given the well-known environmental drawbacks of using fossil fuels, advances in the field of alternative energy have become a worldwide technological priority. Special interest has been focused on the production of biodiesel obtained from oleaginous microorganisms. In the present research, lipid production by two species, microalgae Chlorella pyrenoidosa and yeast Rhodotorula mucilaginosa was assessed, independently and in mixed culture to evaluate a possible synergy. Fatty acid analysis was performed by gas chromatography. Among pure and mixed cultures of both strains and several culturing conditions, the highest biomass and lipid productivity was obtained by C. pyrenoidosa (8.05 and 1.62 g/L, respectively). The results of this study showed that both strains used are in fact oleaginous strains as they were found to reach up to 20 % of lipids, in addition, lipids in both pure and mixed cultures were mainly of triglycerides (>90 %), composed of fatty acid chains between 16 and 18 carbons.

    Use is made of the existing theories about uranium prospecting in sedimentary deposits. A classic method is used for this purpose, that is to say that the geology of the area is studied on the basis of aerial photogrpahy and reconnaissance on the ground for verification. According to the observations on the field it was determined what environments were the most favorable and what formations were susceptible of mineralization. In the studied area the Formation Frio No Marino and Formation Jackson are the most indicated for prospecting. It is suggested to realize detailed studies of paleosedimentation in the above mentioned formations, as well as a general study (stratigraphic) of the Cuenca de Burgos in order to fix the future prospectings

    In addition to oxygen, hydrocarbons are the most reactive chemical compounds produced by plants into the atmosphere. These compounds are part of the family of volatile organic compounds (VOCs) and are discharged in a great variety of forms. Among the VOCs produced by natural sources such as vegetation, the most studied until today are the isoprene and monoterpene. These substances can play an important role in the chemical balance of the atmosphere of a region. In this project, we develop a methodology to estimate the natural (vegetation) emission of isoprene and monoterpenes and applied it to the Monterrey Metropolitan Area, Mexico and its surrounding areas. Landsat-TM data was used to identify the dominant vegetation communities and field work to determine the foliage biomass density of key species. The studied communities were submontane scrub, oak, and pine forests and a combination of both. We carried out the estimation of emissions for isoprene and monoterpenes compounds in the different plant communities, with two different criteria: (1) taking into account the average foliage biomass density obtained from the various sample point in each vegetation community, and (2) using the foliage biomass density obtained for each transect, associated to an individual spectral class within a particular vegetation type. With this information, we obtained emission maps for each case. The results show that the main producers of isoprene are the communities that include species of the genus Quercus, located mainly on the Sierra Madre Oriental and Sierra de Picachos, with average isoprene emissions of 314.6 ton/day and 207.3 ton/day for the two methods utilized. The higher estimates of monoterpenes were found in the submontane scrub areas distributed along the valley of the metropolitan zone, with an estimated average emissions of 47.1 ton/day and 181.4 tons for the two methods respectively.

    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

    This paper presents the final result of an European Space Agency (ESA) activity aimed at improving the software support for LEON processors used in SMP configurations. One of the benefits of using a multicore system in a SMP configuration is that in many instances it is possible to better utilize the available processing resources by load balancing between cores. This however comes with the cost of having to synchronize operations between cores, leading to increased complexity. While in an AMP system one can use multiple instances of operating systems that are only uni-processor capable, a SMP system requires the operating system to be written to support multicore systems. In this activity we have improved and extended the SMP support of the RTEMS real-time operating system and ensured that it fully supports the multicore capable LEON processors. The targeted hardware in the activity has been the GR712RC, a dual-core core LEON3FT processor, and the functional prototype of ESA's Next Generation Multiprocessor (NGMP), a quad core LEON4 processor. The final version of the NGMP is now available as a product under the name GR740. An implementation of the Multicore Task Management API (MTAPI) has been developed as part of this activity to aid in the parallelization of applications for RTEMS SMP. It allows for simplified development of parallel applications using the task-based programming model. An existing space application, the Gaia Video Processing Unit, has been ported to RTEMS SMP using the MTAPI implementation to demonstrate the feasibility and usefulness of multicore processors for space payload software. The activity is funded by ESA under contract 4000108560/13/NL/JK. Gedare Bloom is supported in part by NSF CNS-0934725.

    Full Text Available Primary emissions from anthropogenic and biogenic sources as well as secondary formation are responsible for the pollution levels of ambient air in major urban areas. These sources release fine particles into the air that negatively impact human health and the environment. Organic molecular markers, which are compounds that are unique to specific PM2.5 sources, can be utilized to identify the major emission sources in urban areas. In this study, 43 representative PM2.5 samples, for both daytime and nighttime periods, were built from individual samples collected in an urban site of the Monterrey metropolitan area (MMA during the spring and fall of 2011 and 2012. The samples were analyzed for organic carbon, elemental carbon, and organic molecular markers. Several diagnostic tools were employed for the preliminary identification of emission sources. Organic compounds for eight compound classes were quantified. The n-alkanoic acids were the most abundant, followed by n-alkanes, wood smoke markers, and levoglucosan/alkenoic acids. Polycyclic aromatic hydrocarbons (PAHs and hopanes were less abundant. The carbon preference index (0.7–2.6 for n-alkanes indicates a major contribution of anthropogenic and mixed sources during the fall and the spring, respectively. Hopanes levels confirmed the contribution from gasoline and diesel engines. In addition, the contribution of gasoline and diesel vehicle exhaust was confirmed and identified by the PAH concentrations in PM2.5. Diagnostic ratios of PAHs showed emissions from burning coal, wood, biomass, and other fossil fuels. The total PAHs and elemental carbon were correlated (r2 =  0.39–0.70 across the monitoring periods, reinforcing that motor vehicles are the major contributors of PAHs. Cholesterol levels remained constant during the spring and fall, showing evidence of the contribution of meat-cooking operations, while the isolated concentrations of levoglucosan suggested occasional biomass

    2016-05-01

    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.

    Sierra Leone under the Comprehensive Safeguards Agreements (CSAs) has enacted the Nuclear Safety and Radiation Protection (NSRP) Act 2012 and has given numerous powers to the Authority to implement the above mentioned act fully. The NSRP Act 2012 established the Nuclear Safety and Radiation Protection Authority which among other things to regulate, control and supervise the acquisition, importation, exportation, use, transportation and disposal of radioactive sources and devices emitting Ionizing Radiation. The Authority is bounded by law to cooperate with the International Atomic Energy Agency in the application of Safeguards Agreement and any protocol thereto between Sierra Leone and the International Atomic Energy Agency including conducting inspections and providing any assistance or information required by designated IAEA inspectors in the fulfillment of their responsibilities pursuant to Section 5, Subsection 2, Article xvi of the NSRP Act 2012. The Authority is also granted powers to adopt all necessary measures including a system of licensing to control the export, re-export, transit and transhipment of any nuclear material, equipment or technology in order to protect the safety and security of Sierra Leone. The Regulatory Authority has established departments for the control of nuclear materials: One of which is The Regulatory Control Department; responsible for Inspections, Authorization and Enforcement actions for all radiation sources and nuclear materials. The Authority has been conducting inspections regularly on various facilities ranging from medical radiation generating equipment to industrial radiography sources. The methodology to be used is the issuance of the standard IAEA checklist which is consistent with the Regulatory Authority’s documents for inspection of sources and is in line with the General Safety Requirements(GSR)Part III. The expected outcomes would be increasing training of regulatory authority’s staff, the procurement of

    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.

    Full Text Available The issue of economic participation of over 65 years in Mexico has attracted particular interest due mainly to high rates of participation that holds this age group. Most national and regional research agrees that the social protection system is a key determinant for the decision to participate or not in the labor market by older adults. However, the comparison of different scenarios is not yet widely used practice in this area and do not know deeply the dynamics of this phenomenon. Using two different data sources, this paper intends to compare the employment status of older adults in the state of Mexico and Monterrey, with the ultimate aim of inquiring about the specifics of the phenomenon.

    Trough collections of plants and interviews with 110 individuals, an ethnobotanical study was conducted in order to determine the knowledge and use plant species in Rayones, Nuevo Leon, Mexico. The aim of this study was to record all useful plants and their uses, to know whether differences exist in the knowledge about the number of species and uses between women and men, and to know if there is a correlation between the age of individuals and knowledge of species and their uses. A total of 110 persons were interviewed (56 men, 56 women). Semistructured interviews were carried out. The data were analyzed by means of Student t test and the Pearson Correlation Coeficient. A total of 252 species, 228 genera and 91 families of vascular plants were recorded. Astraceae, Fabaceae and are the most important families with useful species and Agave and Opuntia are the genera with the highest number of useful species. One hundred and thirty six species are considered as medicinal. Agave, Acacia and Citrus are the genera with the highest number of medicinal species. Other uses includes edible, spiritual rituals, construction and ornamentals. There was a non-significant correlation between the person's age and number of species, but a significant very low negative correlation between the person's age and number of uses was found. Knowing their medicinal uses is an important issue for the people of Rayones. Boiling and preparing infusions are the main ways of using plants by residents. The leaves, the branches, and the fruits are the most commonly used parts. Almost 18% of the flora is used for wood and construction purposes. Several uses such as cosmetic, shampoo, firming skin tonics and health hair products recorded in Rayones has not been reported for other areas in the state of Nuevo León. In Rayones, women have a greater knowledge about plants and their uses than men, particularly, medicinal plants, but, men have a greater knowledge about wood and construction species.

    Chronic and degenerative disorders are the leading causes of morbidity-mortality in Mexico, as a result of which the Health Sector has implemented preventive and suitable detection measures. The use of the health services is a dynamic behavior on the part of the population. In order for people to use these preventive measures, the barriers to accessing these services must be lessened. Hence, the objective of this study was that of ascertaining the use of the services for the detection of diabetes mellitus, high blood pressure, cervical-uterine and breast cancer and tetanus and diphtheria toxoide vaccinations. The sample size was that of 254 individuals age 25 and over living in Monterrey or in the greater Monterrey metropolitan area. Those having employed preventive measures during the year immediately prior to the study were taken into account with regard to the use of preventive measures. The analysis consisted of descriptive statistics and bivariate analysis. Over 60% of the population was female, the average age being 42.3 + 14 years of age, three fourths of the population being on the social security rolls. A total 37% mentioned having undergone the diabetes test, and 44.5 the test for high blood pressure, while 31.1% had been vaccinated with the tetanus and diphtheria toxoide. Regarding specifically female checkups, 34.3% of all females had undergone the corresponding cervical-uterine cancer test, 29.5% having been screened for breast cancer. No relationship was found to exist between the use of measures and family histories and the perception of the importance of the checks. The use of preventive measures fall below some international standards. Individuals exposed to the risk must be sought in order to fittingly detect any chronic disorder.

    Full Text Available The 2014 outbreak of Ebola virus disease (EVD in West Africa was the largest in history. Starting in September 2014, International Medical Corps (IMC operated five Ebola treatment units (ETUs in Sierra Leone and Liberia. This paper explores how future infectious disease outbreak facilities in resource-limited settings can be planned, organized, and managed by analyzing data collected on water, sanitation, and hygiene (WASH and infection prevention control (IPC protocols.We conducted a retrospective cohort study by analyzing WASH/IPC activity data routinely recorded on paper forms or white boards at ETUs during the outbreak and later merged into a database from two IMC-run ETUs in Sierra Leone between December 2014 and December 2015.The IMC WASH/IPC database contains data from over 369 days. Our results highlight parameters key to designing and maintaining an ETU. High concentration chlorine solution usage was highly correlated with both daily patient occupancy and high-risk zone staff entries; low concentration chlorine usage was less well explained by these measures. There is high demand for laundering and disinfecting of personal protective equipment (PPE on a daily basis and approximately 1 (0-4 piece of PPE is damaged each day.Lack of standardization in the type and format of data collected at ETUs made constructing the WASH/IPC database difficult. However, the data presented here may help inform humanitarian response operations in future epidemics.

    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.

    As of April 2010, all maternity care at government healthcare facilities in Sierra Leone is provided at no cost to patients. In late 2010, we conducted a community health census of 18 sections of the city of Bo (selected via randomized cluster sampling from 68 total sections). Among the 3421 women with a history of pregnancy who participated in the study, older women most often reported having a history of both home and hospital deliveries, while younger women showed a preference for hospital births. The proportion of lastborn children delivered at a healthcare facility increased from 71.8% of offspring 10-14 years old to 81.1% of those one to nine years old and 87.3% of infants born after April 2010. These findings suggest that the new maternal healthcare initiative has accelerated an existing trend toward a preference for healthcare facility births, at least in some urban parts of Sierra Leone. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

    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.

    We compared children who were positive for Ebola virus disease (EVD) with those who were negative to derive a pediatric EVD predictor (PEP) score. We collected data on all children <13 years of age admitted to 11 Ebola holding units in Sierra Leone during August 2014–March 2015 and performed multivariable logistic regression. 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

    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.

    Full Text Available Breast cancer has been described as one of the life-threatening diseases affecting women and is a major problem in women’s health issues. The unrecorded number of cases of breast lumps and breast cancer observed in women in Sierra Leone prompted the researcher to organize a “Breast Week” during which 1 200 women were educated on breast cancer and the importance of breast health. This research is a follow up of the “Breast Week” which was organized in Freetown, Sierra Leone The specific objective of this study was to assess whether the knowledge and teachings given to the women who participated in this project was fully understood. A sample size of 120 women (10% who participated in the “Breast Week” was obtained through systematic sampling. A quantitative approach was adopted and a structured interview schedule guided the data collection process. The data were processed through use of SPSS and Microsoft Excel. Texts from open ended questions were categorized and frequency counts were applied to the data. It was found that the majority (96.6% of the women had some knowledge of breast cancer. They linked breast cancer to the signs and symptoms associated with it and were able to describe the disease as one that kills women if not promptly detected and/or treated appropriately. Findings indicate that the majority of the women are aware of the dangers of the disease and had knowledge of someone who had died of breast cancer (59.2%. An assessment of the effectiveness of knowledge on breast cancer showed that these women could identify breast cancer as a disease that affects women and may cause death if not detected on time.

    Full Text Available Several socioeconomic factors are associated with poor oral hygiene habits. A version of the Oral Hygiene Habits Scale (OHHS was developed in Mexico to measure these factors; however, its relationship with sociodemographic variables has not been studied. The verification of these relationships could contribute to the validation of the scale. Objective: To evaluate the relationship between oral hygiene habits and sociodemographic variables of sex, age, schooling, self-defined socioeconomic stratum, occupation and marital status in the general and clinical population of Monterrey, Mexico. Materials and Methods: A general population sample (GPS of 256 participants and a clinical sample (CPS of 240 participants were studied. The OHHS consisted of an eight-item Likert scale of 4 points ranging from 0 to 4. A descriptive correlational study was performed with a cross-sectional design. Data were analyzed using the Mann-Whitney U test, Kruskal-Wallis test, Spearman correlation coefficient, Cramer's V coefficient, and multivariate aligned rank test. Results: In GPS and CPS groups, OHHS was related to sex, schooling, socioeconomic stratum, occupation and marital status, but not to age. There were no significant interactions between the samples (GPS and CPS and sociodemographic variables. Conclusion: There is a statistically significant relationship between oral hygiene habits and some sociodemographic variables in the general and clinical population. This relationship supports the validity of the OHHS.

Results indicated that 67%, 65% and 7% of the adolescents, respectively, accepted they had already used alcohol, tobacco and marihuana at some time in their life and that 33%, 38% and 3%, respectively, had used these same substances over the last month; 65% consider most of their colleagues have used these substances; 56% had to reject an offer to consume alcohol, 64% tobacco and 51% marihuana over the last month. On the basis of these findings, we recommend the implementation of a prevention program aimed at supporting the adolescent's resources to resist pressure towards consumption.

    Full Text Available ¿Hay hoy razones filosóficas fuertes y plausibles para ser ateo o, en todo caso, para rechazar la religión? «El Nuevo Ateísmo» ofrece argumentos propios de una razón científica neopositivista, para criticar las creencias religiosas. Sus autores lo hacen aduciendo logros actuales de las ciencias, sin tener nunca en cuenta sus límites intrínsecos y mostrando gran desconocimiento de la interpretación de las creencias religiosas por parte de las comunidades que las profesan. Se muestran especialmente críticos con lo que consideran el potencial de violencia de dichas creencias. Su difusión no hay que buscarla en sus aportaciones teóricas, sino en haber generado un movimiento cultural en la web, con una influencia inimaginable por los ateos clásicos. Dialogar críticamente con el Nuevo Ateísmo requiere poner a punto los argumentos filosóficos en el contexto de la cultura científica actual. En particular, la cuestión del naturalismo, difundida como naturalización de la espiritualidad, «el problema realmente duro» de las neurociencias.

  8. A biomass energy flow chart for Sierra Leone

    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

    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

    Full Text Available Por más de 60 años se dispuso solo de tres grupos farmacológicos para el tratamiento de la diabetes mellitus (DM: la insulina, la metformina y las sulfonilureas. Sin embargo, en los últimos años y como consecuencia de los avances en el conocimiento de la patogenia de la DM2 se han desarrollado nuevos fármacos con novedosos mecanismos de acción y con diferentes perfiles de seguridad, entre ellos los compuestos con efecto incretina y los glucosúricos que actúan en los trastornos a nivel intestinal y renal presentes en la DM2. La disponibilidad de múltiples opciones terapéuticas está produciendo profundos cambios en la terapia farmacológica de la DM2. Se logran enfoques terapéuticos más fisiopatológicos pero sobre todo permiten un manejo más personalizado y ajustado a las características y riesgos individuales de los pacientes, privilegiando junto al control glicémico, la seguridad terapéutica. En esta revisión se analizarán los nuevos fármacos con efecto incretina, los agonistas del péptido similar al glucagón tipo 1 (AR-GLP1 e inhibidores de la dipeptidil peptidasa 4 (IDPP-4, y los inhibidores de los cotransportadores sodio-glucosa tipo 2 (ISLGT2 que aumentan la excreción renal de glucosa.

Las nuevas formas de interacción, con los contenidos y los cambios en el consumo mediático motivados por la movilidad y las nuevas interfaces, han producido alteraciones importantes en los propios medios de comunicación que han tenido que adaptarse a esta nueva realidad.Tomando como punto de partida el concepto original de Ecología, tratamos de identificar un conjunto de  elementos que ayuden a aclarar el concepto de  Ecosistema Mediático, en particular en lo que respecta a los diversos factores que influyen en él. Se trata de trazar un paralelo entre los dos ecosistemas –biológico y mediático­­–  buscando formas de integrar las novedades relacionadas con la evolución técnica de los medios, las herramientas y aplicaciones que están cambiando las funciones y contenidos de los medios tradicionales, o alterando la forma de consumo mediático.La propuesta que se hace busca la integración de nuevos conceptos que ahora se estudian de forma fragmentada y, a veces, descontextualizada del nuevo entorno mediático.

    Full Text Available 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 study of intimate partner relationships is particularly important because this union is the foundation of the family. Satisfaction with the relationship can be defined as the overall attitude to the relationship and the partner. The Hendrick's Relationship Assessment Scale (RAS is a instrument commonly used to assess the construct. Previous research papers have showed that this scale has high internal consistency and a single-factor structure. Although there are validation studies of the RAS, these studies used inappropriate statistical techniques to analyze its Likert-type items, and to determine the number of factors; likewise, its factor invariance across sex has not been previously contrasted. Therefore, this study posed the following research questions: Does the RAS have consistent and discriminating items? Basing the analysis on a polychoric correlation matrix, what is its level of internal consistency? How many factors emerge using rigorous empirical methods? Is the single-factor model invariant across sex? In order to answer these research questions, we used a random route probability sampling in this instrument validation study of the RAS. The sample was extracted from the population of married couples or the ones living in consensual union in Monterrey, Mexico. There were 431 female and 376 male participants in the study. The RAS’ items were consistent and discriminative. The internal consistency of the scale was excellent in the whole sample (ordinal α = .93, as well as among female (ordinal α = .94 and male participants (ordinal α = .92. Horn's parallel analysis and Velicer's  minimum average partial test suggested a one factor solution. Moreover, the single-factor model (with one correlation between the residuals of the two negatively worded items had a close fit to the data, and its properties of invariance across sex were very acceptable by the Unweighted Least Squares method. We conclude that the scale shows internal

    We use data from Sierra Leone where a substantial education program provided increased access to education for primary-school age children but did not benefit children who were older. We exploit the variation in access to the program generated by date of birth and the variation in resources between various districts of the country. We find that…

    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.

    .: seis de hembras capturadas en cebo humano, dos de nulíparas y dos colectadas en reposo intradomiciliar. Cada muestreo incluyó 60 hembras, en tres colonias endémicas para dengue, en Monterrey, Nuevo León, México, entre 1994 y 1996. Las hembras grávidas o con sangre en estómago fueron excluidas. Cada mosquito fue llevado al laboratorio y alimentado a repleción con sangre humana, y a las 48 horas los ovarios fueron disecados para registrar si estaban en fase gonoactiva o no. El tamaño corporal fue registrado por la longitud en mm del ala izquierda de cada mosquito. Se usó regresión logística para estimar la probabilidad de que una hembra fuera no gonoactiva, como una variable binaria, en función de la longitud alar, y del tipo de colecta. RESULTADOS: De las 600 hembras procesadas, 164 (27% permanecieron no gonoactivas, y su tamaño corporal mostró un intervalo (1.9-3.2 mm casi igual al total de las hembras (1.8-3.3 mm. El modelo de regresión logística fue significativo para estimar la probabilidad de que una hembra permanezca no gonoactiva (Y=1. El tipo de colecta no tuvo influencia significativa en la variable binaria, pero la probabilidad de no gonoactividad mostró una relación inversa con el tamaño corporal. CONCLUSIONES: Las poblaciones del vector del dengue en Monterrey, México, están integradas por hembras de tamaño muy variable. La regresión logística resultó útil para evaluar la probabilidad que tiene una hembra de quedar no gonoactiva después de una alimentación sanguínea. La necesidad de una segunda comida sanguínea está presente en cualquier mosquito, pero los pequeños tienen una mayor probabilidad de picar por segunda ocasión a una persona en un periodo de dos días, para poder madurar huevos.

    The Lancet Commission on Global Surgery estimated that low/middle-income countries will lose an estimated cumulative loss of US$12.3 trillion from gross domestic product (GDP) due to the unmet burden of surgical disease. However, no country-specific data currently exist. We aimed to estimate the costs to the Sierra Leone economy from death and disability which may have been averted by surgical care. We used estimates of total, met and unmet need from two main sources-a cluster randomised, cross-sectional, countrywide survey and a retrospective, nationwide study on surgery in Sierra Leone. We calculated estimated disability-adjusted life years from morbidity and mortality for the estimated unmet burden and modelled the likely economic impact using three different methods-gross national income per capita, lifetime earnings foregone and value of a statistical life. In 2012, estimated, discounted lifetime losses to the Sierra Leone economy from the unmet burden of surgical disease was between US$1.1 and US$3.8 billion, depending on the economic method used. These lifetime losses equate to between 23% and 100% of the annual GDP for Sierra Leone. 80% of economic losses were due to mortality. The incremental losses averted by scale up of surgical provision to the Lancet Commission target of 80% were calculated to be between US$360 million and US$2.9 billion. There is a large economic loss from the unmet need for surgical care in Sierra Leone. There is an immediate need for massive investment to counteract ongoing economic losses. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Durante los últimos años el rendimiento ha aumentado constantemente, por lo cual crecía la cantidad de polvo y gases de expulsión. Con el montaje de una instalación para la separación del polvo por ciclones, se consiguió una disminución importante del polvo, pero no se resolvió el problema de los humos. Se hicieron ensayos muy costosos de separación de polvo por humedad y por filtros Lühr, en parte en Kiefersfelden y en parte en la sucursal de Blaubeuren, pero sin el éxito esperado. Es cierto que se habían empleado filtros eléctricos en instalaciones más antiguas, pero en nuestros hornos modernos, de alto rendimiento, que funcionan muy económicamente, se había prohibido su empleo, a causa de la baja temperatura de los gases. Este problema se ha resuelto hace poco tiempo. En Blaubeuren se ha conseguido mantener automáticamente la temperatura de los gases constantemente en la misma altura, de manera que ahora se pueden usar allí los filtros eléctricos. Esta posibilidad existe también en Kiefersfelden, pero sería preciso parar los hornos por algún tiempo y transformarlos uno por uno. Como la región de Kiefersfelden tiene un paisaje hermoso, pero circundado por montañas, el humo se nota mucho más que en regiones situadas en el llano. A pesar de los gastos considerables, la Dirección decidió cambiar y montar un gran nuevo horno.

    Improper use of antibiotics increases antimicrobial resistance. Evaluate the use of antibiotics and the impact of an intervention designed to improve antibiotic prescription for surgical prophylaxis in 6 hospitals of Monterrey, Mexico. Design: A prospective multicenter survey and a pretest-postest experimental study. Phase 1: Survey to evaluate the use of antibiotics through an especially designed guide. Phase 2: Intervention designed to improve antibiotic prescription for surgical prophylaxis by the medical staff by using printed, audiovisual and electronic messages. Phase 3: Survey to evaluate the impact of the intervention. Frequencies, percentages, medians, ranges and X 2 test. Phase 1: We evaluated 358 surgical patients, 274 prophylactic antibiotic regimens. A total of 96% of antibiotics regimens began with inappropriate timing (290/302), 82.8% were inappropriate regimens (274/331), 77.7% were in inappropriate dosage (230/296), 86% of inadequate length (241/280), and in 17.4% restricted antibiotics were used (52/299). Phase 2: 9 sessions including 189 physicians (14 department chairs, 58 general practitioners and 117 residents). Phase 3: We evaluated 303 surgical patients, 218 prophylactic antibiotics regimens. Inappropriate treatment commencement was reduced to 84.1% (180/214) (P<0.001), inappropriate regimens to 75.3% (162/215) (P=0.03), inappropriate dosages to 51.2% (110/215) (P<0.001), and use of restricted antibiotics to 8.3% (18/215) (P=0.003). Inappropriate use of prophylactic antibiotics in surgery is a frequent problem in Monterrey. The intervention improved the antibiotic prescription for surgical prophylaxis by reducing inappropriate treatment commencement, regimens, dosages, and overuse of restricted antibiotics. It is necessary to strengthen strategies to improve the prescription of antibiotics in surgical prophylaxis. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A.

    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.

    The largemouth bass Micropterus salmoides is a very valuable fish species for aquaculture and sport fishing; however, there are no systematic studies on fish metazoan parasites in Mexico. The main objective of the present study was to describe the prevalence, abundance, and intensity of M. salmoides metazoan parasites, and their association with fish condition factor and gender. The sample size was composed by 672 hosts, collected between 2011-2013 from the following reservoirs of Nuevo Leon, México: Rodrigo Gómez dam (“La Boca”, LB), Cuchillo-Solidaridad dam (CS), Salinillas lagoon (LS), Mariano Escobedo dam (“Sombreretillo”, S), and José López Portillo dam (“Cerro Prieto”, CP). Living fish were transported to the laboratory; sizes and weights were then recorded to calculate the Fulton condition factor (k). If possible, gender was also recorded. Parasites were detected under stereoscopy, recollected and preserved by traditional techniques. Statistical analysis of association between parasitic load, gender, and Fulton condition factor were calculated, using the X2 and the Student-t tests. Results showed that 12 different metazoans were identified, two flukes (Posthodiplostomum minimum centrarchi and Phyllodistomum pearsei), one tapeworm (Proteocephalus ambloplitis), three roundworms (Contracaecum sp., Spinitectus carolini and Philometra nodulosa), two acantocephalan (Neoechinorhynchus cylindratus and Arhythmorhynchus sp.), one leech (Myzobdella moorei), and three copepods (Ergasilus versicolor; Ergasilus arthrosis and Ergasilus cerastes). HSD Tukey test showed that infected fish from LB were significantly different than LS, CS, CP, and S (PParasites most commonly collected in all five locations were P. m. centrarchi, Contracaecum sp. and E. versicolor.

    1979-09-01

    The interface between innovation diffusion and economic development and social change in Third World settings is investigated. The paper first presents a conceptual framework linking diffusion processes and development and then exemplifies a portion of that framework by examining the diffusion of agricultural cooperatives in Sierra Leone from 1948 through 1967. Attention is then turned to elements of the historical development of a cooperative movement in Sierra Leone which are important for understanding the processes underlying that diffusion. The temporal and spatial patterns of diffusion are discussed and the statistical analyses that assess (1) which variables provide a basis for distinguishing political units with cooperatives from those without, and (2) which variables account for the differences in the time at which cooperatives were established are examined. The findings are integrated with the theory presented. 41 references.

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.

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

    Directory of Open Access Journals (Sweden)

    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.

    Although surgery is increasingly recognized as an essential component of primary health care, there has been little documentation of surgical programs in low- and middle-income countries. Surgeons OverSeas (SOS) is a New York-based organization with a mission to save lives in developing countries by improving surgical care. This article highlights the surgical program in Sierra Leone as a possible model to improve access to surgery. An SOS team conducted a needs assessment of surgical capacity in Sierra Leone in February 2008. Interventions were then developed and programs were implemented. A follow-up assessment was conducted in December 2009, which included interviews of key Sierra Leone hospital personnel and a review of operating room log books. Based on an initial needs assessment, a program was developed that included training, salary support, and the provision of surgical supplies and equipment. Two 3-day workshops were conducted for a total of 44 health workers, salary support given to over 100 staff, and 2 containers of supplies and equipment were donated. Access to surgery, as measured by the number of major operations at Connaught Hospital, increased from 460 cases in 2007 to 768 cases in 2009. The SOS program in Sierra Leone highlights a method for improving access to surgery that incorporates an initial needs assessment with minimal external support and local staff collaboration. The program functions as a catalyst by providing training, salary support, and supplies. The beneficial results of the program can then be used to advocate for additional resources for surgery from policy makers. This model could be beneficial in other resource-poor countries in which improved access to surgery is desired. Copyright 2010 Association of Program Directors in Surgery. Published by Elsevier Inc.

    The Momotombo volcano has a special place in the history of Nicaragua. It is perfectly visible from the Capital, Managua, and from the major city of Leon. The old capital "Leon Viejo", founded in 1524 was abandoned in 1610, after a series of earthquakes and some major eruptions from Momotombo. The site was subsequently covered by Momotombo ash. A major geothermal power plant stands at the base of the volcano. Momotombo had been dormant for a hundred years, but had maintained high fumarole temperatures (900°C), indicating magma had been close to the surface for decades. In recent years, seismic activity has increased around the volcano. In December 2015, after a short ash eruption phase the volcano erupted lava, then a string of Vulcanian explosions. The volcano is now in a phase of small Vulcanian explosions and degassing. The Leon Viejo World Heritage site is at risk to mainly ash fall from the volcano, but the abandonment of the old city was primarily due to earthquakes. Additional risks come from high rainfall during hurricanes. There is an obvious link between the cultural site (inscribed under UNESCO cultural criteria) and the geological environment. First, the reactivation of Momotombo volcano makes it more important to revise the hazard of the site. At the same time, Leon Viejo can provide a portal for outreach related to the volcano and for geological risk in general. To maximise this, we provide a geosite inventory of the main features of Momotombo, and it's environs, that can be used as the first base for such studies. The volcano was visited by many adventure tourists before the 2015/2016 eruption, but is out of bounds at present. Alternative routes, around the volcano could be made, to adapt to the new situation and to show to visitors more of the geodiversity of this fascinating volcano-tectonic and cultural area.

    The outbreak of Ebola virus disease (EVD) in West Africa between 2014 and 2015 was the largest EDV epidemic since the identification of Ebola virus (EBOV) in 1976, and the countries most strongly affected were Sierra Leone, Guinea, and Liberia. The Sierra Leone-China Friendship Biological Safety Laboratory (SLE-CHN Biosafety Lab), a fixed Biosafety Level 3 laboratory in the capital city of Sierra Leone, was established by the Chinese government and has been active in EBOV detection since 11 March 2015. Complete management and program documents were created for the SLE-CHN Biosafety Lab, and it was divided into four zones (the green, yellow, brown, and red zones) based on the risk assessment. Different types of safe and appropriate personnel protection equipment (PPE) are used in different zones of the laboratory, and it fully meets the Biosafety Level 3 laboratory standards of the World Health Organization. Good preparedness, comprehensive risk assessment and operation documents, appropriate PPE, effective monitoring and intensive training, together with well-designed and reasonable laboratory sectioning are essential for guaranteeing biosafety.

    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.

    Viral hepatitis is a contagious disease. Patients infected with hepatitis B virus (HBV) or hepatitis C virus (HCV), may be either chronically symptomatic or asymptomatic, and suffer cirrhosis and high risk of hepatic carcinoma. Asymptomatic carriers of HBV surface antigen (HBs-Ag) or with anti-HCV antibodies are potentially infectious, and therefore a risk to public health. This work seeks to establish the frequency of seropositivity for HBs-Ag and anti-HCV antibodies in a population of 774 newly accepted students of the Medical School of the Autonomous University of Nuevo Leon, whose average age was 18 years. Second generation ELISA test were used to screen for HBs-Ag and anti-HCV antibodies. HBs-Ag was confirmed by a neutralization test and anti-HCV antibodies were confirmed by a RIBA test. Three sera were positive for HBs-Ag by ELISA and only one serum (0.13% of analyzed samples) was confirmed by the neutralization technique. On the other hand 12 sera were positive for anti-HCV antibodies by ELISA, and eight of these were confirmed by RIBA (1.03% of the analyzed samples). Intensive reactivity bands were found in two sera, and weak reactivity bands were found in six sera. ELISA screening for anti-HCV antibodies showed 0.5% of false positives. This study shows that the frequency of anti-HCV antibodies is 7.95% times higher than that found for HBs-Ag. All seropositive patients were asymptomatic and potentially infective. This demonstrates the need to routinely screen for HBs-Ag and anti-HCV antibodies to establish the prevalence of these diseases in our area.

    Air pollution is a serious health problem in major cities in Mexico. The concentrations of monitored criteria pollutants have been above the US National Ambient Air Quality Standards for the last decade. To determine whether the number of primary malignant nasal and paranasal neoplasms has increased, we surveyed 256 such cases admitted to a major adult oncology hospital located in metropolitan Mexico City (MMC) for the period from 1976-1997 and to a tertiary hospital in Monterrey, an industrial city, for the period from 1993-1998. The clinical histories and histopathologic material were reviewed, and a brief clinical summary was written for each case. In the MMC hospital the number of newly diagnosed nasal and paranasal neoplasms per year for the period from 1976-1986 averaged 5.1, whereas for the next 11 years it increased to 12.5. The maximal increase was observed in 1995-1997, with an average of 20.3 new cases per year (P = 0.0006). The predominant neoplasms in these series were non-Hodgkin's lymphoma, squamous cell carcinoma, melanoma, adenocarcinoma, Schneiderian carcinoma, and nasopharyngeal carcinoma. In the Monterrey hospital a 2-fold increase in the numbers of newly diagnosed nasal and paranasal neoplasms was recorded between 1993 and 1998. The predominant MMC neoplasm in this series, namely nasal T-cell/natural killer cell non-Hodgkin's lymphoma, is potentially Epstein-Barr virus related. Nasal and paranasal malignant neoplasms are generally rare. Environmental causative factors include exposure in industries such as nickel refining, leather, and wood furniture manufacturing. Although epidemiologic studies have not addressed the relationship between outdoor air pollution and sinonasal malignant neoplasms, there is strong evidence for the nasal and paranasal carcinogenic effect of occupational aerosol complex chemical mixtures. General practitioners and ear, nose, and throat physicians working in highly polluted cities should be aware of the clinical

    Full Text Available Type 2 diabetes mellitus (T2DM is one of the leading causes of death from worldwide non-communicable diseases. The prevalence of diabetes in the Mexico (MX–United States border states exceeds the national rate in both countries. The economic burden of diabetes, due to decreased productivity, disability, and medical costs, is staggering and increases significantly when T2DM-related complications occur. The purpose of this study was to use a modified behavioral risk factor surveillance system (BRFSS to describe the T2DM self-management behaviors, diabetes care, and health perception of a convenience sample of adults with T2DM in Monterrey, MX. This cross-sectional study design, with convenience sampling, was conducted with a convenience sample (n = 351 of adults in the metropolitan area of Monterrey, MX who self-reported a diagnosis of T2DM. Potential participants were recruited from local supermarkets. Twenty-six diabetes and health-related items were selected from the BRFSS and administered in face-to-face interviews by trained data collectors. Data analysis was conducted using descriptive statistics. The mean age was 47 years, and the mean length of time with T2DM was 12 years. The majority was taking oral medication and 34% required insulin. Daily self-monitoring of feet was performed by 56% of the participants; however, only 8.8% engaged in blood glucose self-monitoring. The mean number of health-care provider visits was 9.09 per year, and glycated hemoglobin level (HbA1c was assessed 2.6 times per year. Finally, only 40.5% of the participants recalled having a dilated eye exam. We conclude the modified BRFSS survey administered in a face-to-face interview format is an appropriate tool for assessing engagement in T2DM self-management behaviors, diabetes care, and health perception. Extension of the use of this survey in a more rigorous design with a larger scale survey is encouraged.

    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)

    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

    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. 232Th-series, 238U-series, 40K and 137Cs activity concentrations (AC, Bq kg-1) were determined by gamma spectrometry with a high purity Ge detector. 238U and 234U ACs were obtained by liquid scintillation and alpha spectrometry with a surface barrier detector. Dating of core sediments was performed applying CRS method to 210Pb activities. Results were verified by 137Cs AC. Resulting activity concentrations were compared among corresponding surface and core sediments. High 238U-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) 234U/overflow="scroll">238U and 238U/overflow="scroll">226Ra in sediments have values between 0.9-1.2, showing a behavior close to radioactive equilibrium in the entire basin. 232Th/overflow="scroll">238U, 228Ra/overflow="scroll">226Ra ARs are witnesses of the different geological origin of sediments from San Marcos and Luis L.

    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.

    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. Leon reservoirs

    The critical shortage of human resources for healthcare falls most heavily on sub-Saharan nations such as Sierra Leone, where such workforce deficits have grave impacts on its burden of surgical disease. An important aspect in retention and development of the workforce is training. This study focuses on postgraduate surgical training (formal and short course) and perceptions of opportunities, challenges and aspirations, in a country where more than half of surgical procedures are performed by medical officers. The study presents findings from 12 in-depth semi-structured interviews conducted with medical officers by the primary investigator in Sierra Leone between April and June 2017. Each interview was transcribed alongside an introspective reflexive journal to acknowledge and account for researcher biases. Two interviewees had accessed postgraduate surgical training and 10 (83%) had accessed short course surgically relevant training. The number of short courses accessed grew higher the more recently the medical officers had graduated. Supervision, short length and international standards were the most appreciated aspects of short training courses. Some medical officers perceived the formal postgraduate surgical training programme to be ill-equipped, doubting its credibility. This demotivated some from applying. Training is an essential aspect of developing an adequate surgical workforce. Faith must be restored in the capabilities of Sierra Leone's Ministry of Health and Sanitation to provide adequate and sustainable training. This study advocates for the use of short courses to restore this faith and the expansion of postgraduate surgical training to the districts through developing a regional teaching complex to provide short courses and eventually formal postgraduate training in the future.

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.

    In Sierra Leone constraints to ideal maternal health require a primary health care approach that includes collaboration with traditional midwives. They are authoritative figures embedded within local political structures and a powerful women's religion. The local causes of maternal risk are described, including civil war and refugee camp life. Traditional midwives provide vital services in the camp, are respected for their social status, and learn additional skills. Biomedical and traditional systems of authoritative knowledge, based on different kinds of legitimacy to heal, are in a complementary relationship.

    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.

    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.

    Ebola Treatment Units were able to provide only 60% of necessary treatment beds in Sierra Leone. As a result, the Government of Sierra Leone decided to construct Community Care Centers. These were intended to increase treatment-seeking behavior and reduce the community-level spread of Ebola by facilitating access to care closer to communities. Through qualitative data collection in 3 districts, this study seeks to understand the perceived impact that proximity to such Centers had on treatment-seeking behavior. Feedback from community members and Community Health Volunteers indicates that proximity to treatment reduced fears, especially those arising from the use of ambulances, lack of familiarity with medical Centers, and loss of contact with family members taken for treatment. Participants report that having a Center close to their home enables them to walk to treatment and witness survivors being discharged. Living close to Centers also enables communities to be involved in their design and daily operation, helping to build trust in them as acceptable treatment facilities. Further research is required to understand the appropriate design, operation, and epidemiological impact of Centers. Further investigation should incorporate the effect of an outbreak's severity and the stage (duration) of the outbreak on potential acceptance of Centers.

    Following the 2014 Ebola virus disease (EVD) outbreak in West Africa, the UK Department for International Development funded South London and Maudsley National Health Service (NHS) to develop a psychological intervention that ex-Ebola Treatment Centre (ETC) staff could be trained to deliver to their peers to improve mental health in Sierra Leone. The two key aims were to assess the feasibility of training a national team to deliver a cognitive behavioural therapy (CBT)-based group intervention, and to evaluate the effectiveness of the overall intervention within this population. UK clinicians travelled to Sierra Leone to train a small team of ex-ETC staff in a three-phased CBT-based intervention. Standardised clinical measures, as well as bespoke measures, were applied with participants through the intervention to assess changes in mental health symptomology, and the effectiveness of the intervention. The results found improvements across all factors of mental health in the bespoke measure from phase 1 to phase 3. Additionally, the majority of standardised clinical measures showed improvements between phase 2 and the start of phase 3, and pre- and post-phase 3. Overall, the findings suggest that it is possible to train staff from ETCs to deliver effective CBT interventions to peers. The implications of these results are discussed, including suggestions for future research and clinical intervention implementation within this population. The limitations of this research are also addressed.

    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.

Methods This study applies the data envelopment analysis (DEA approach to analyse technical efficiency of random samples of 36 MCHPs, 22 CHCs and 21 CHPs using input and output data for 2008. Results The findings indicate that 77.8% of the MCHPs, 59.1% of the CHCs and 66.7% of the CHPs were variable returns to scale technically inefficient. The average variable returns to scale technical efficiency was 68.2% (SD = 27.2 among the MCHPs, 69.2% (SD = 33.2 among the CHCs and 59% (SD = 34.7 among the CHPs. Conclusion This study reveals significant technical inefficiencies in the use of health system resources among peripheral health units in Kailahun and Kenema districts of Sierra Leone. There is need to strengthen national and district health information systems to routinely track the quantities and prices of resources injected into the health care systems and health service outcomes (indicators of coverage, quality and health status to facilitate regular efficiency analyses.

    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.

Sin embargo, pocos han tomado seriamente como objeto de estudio uno de los platillos más emblemáticos de la comida mexicana: los tacos callejeros. El presente artículo esboza primeramente la génesis de la venta de tacos en la calle a través de una perspectiva socio-histórica. Contrariamente a la creencia, según la cual el mercado de los tacos es inmemorial, esta etnografía histórica demuestra la manera en la que nace el mercado callejero de tacos a mediados del siglo XX. Algunos factores macro estructurales como la industrialización de la tortilla, el crecimiento demográfico, los límites del modelo de sustitución de importaciones y la subalimentación explican la emergencia y la proliferación de los puestos de tacos en las calles de Monterrey. Aunada a una lectura micro social, esta etnografía identifica las principales características del mercado callejero de tacos (incertidumbre cualitativa, asimetría de la información, discrepancias de evaluación. Esas características permiten comprender la forma en que funciona el mercado de tacos. Gracias a una descripción etnografía detallada damos cuenta del trabajo social que existe detrás de las transacciones económicas de alimentos de dudosa procedencia.

Por ello, la Psicomotricidad en la escuela no es una técnica, una materia más, es, en todo caso, un enfoque que atiende a la globalidad del niño, a la revalorización del cuerpo y del movimiento en ese ámbito. En segundo lugar exponemos sobre la «hora de Psicomotricidad» o la «sesión de Psicomotricidad», donde alumnos, maestros y Psicomotricista comparten una hora semanal, favoreciendo el juego corporal y la actividad espontánea a partir del ofrecimiento de objetos que operan como disparadores y acompañantes.

    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.

    Full Text Available La fibrilación auricular es la arritmia más frecuente y se relaciona con una alta tasa de accidente cerebrovascular y embolia sistécmica. La terapia establecida tanto para prevención primaria como secundaria es la anticoagulación con warfarina, antagonista de la vitamina K. Existen escalas que predicen el riesgo tromboembólico y la probabilidad de beneficiarse de terapia antitrombótica. El CHADS2 ha sido la más simple y ampliamente utilizada, pero actualmente el CHA2DS2-VASc ha incorporado otros factores de riesgo, otorgando una mejor estratificación. El estrecho margen terapécutico de la warfarina y la interacción con fármacos y alimentos requiere controles seriados de la intensidad de la anticoagulación, limitando su uso clínico. Han aparecido nuevos anticoagulantes que ofrecen ventajas sobre los antagonistas de vitamina K. Estos actúan en dos sitios distintos de la cascada de la coagulación: inhibiendo directamente la trombina como el dabigatran, o el factor X activado como el rivaroxaban, apixaban, edoxaban y betrixaban. Estos nuevos fármacos han ido reemplazando a la warfarina y ya están incluidos en las guías de manejo de fibrilación auricular no valvular.

    Full Text Available Hace algo más de diez años, siendo Decano de la Facultad de Ciencias Económicas de la Universidad Nacional, tuve el honor de ser el primer expositor en el primer congreso de estudiantes de economía del país. Once años después, recae de nuevo en mí ese honor, y por ello debo expresar mi gratitud a los estudiantes organizadores de este cuento. Entre aquel primer congreso y éste se transformó no sólo el panorama del quehacer profesional sino también el panorama global de la ciencia económica, y creo que en forma radical. En poco más de veinte años, desde comienzos de los años setenta, se abrieron nuevos rumbos que, sin duda, quienes hoy son estudiantes seguirán en el futuro.

    Full Text Available En estas dos últimas décadas, en América Latina han surgido diversos movimientos sociales que a su vez han producido la aparición de nuevos sujetos colectivos, especialmente significativos dentro de los sectores populares. El Perú es una expresión evidente de este fenómeno social y presenta en su panorama nacional diversos indicadores del mismo, dentro de una situación peculiar: la crisis socio-económica y la violencia generalizada que estamos viviendo. Uno de estos nuevos sujetos sociales es sin duda la mujer, que ha pasado de ser una marginada social a desempeñar un protagonismo dentro de las organizaciones populares. Su participación en la actividad comunal y en la sindical, ha sido generada casi siempre por las reacciones colectivas de reinvindicación y defensa de derechos primarios como alimentación, salud, vivienda y educación.

  16. 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.

    The formal series symmetry approach (FSSA), a quite powerful and straightforward method to establish infinitely many generalized symmetries of classical integrable systems, has been successfully extended in the supersymmetric framework to explore series of infinitely many generalized symmetries for supersymmetric systems. Taking the 𝒩 = 1 supersymmetric Boiti-Leon-Manna-Pempinelli system as a concrete example, it is shown that the application of the extended FSSA to this supersymmetric system leads to a set of infinitely many generalized symmetries with an arbitrary function f (t). Some interesting special cases of symmetry algebras are presented, including a limit case f (t) = 1 related to the commutativity of higher order generalized symmetries.

    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.

    The country programme summary reported here is one in the series of such studies being undertaken of the Agency's TC programme with Member States. With over $1.1 million of Agency support received, Sierra Leone ranks 70th among all recipients of technical assistance in the period 1958 through 1991. Almost equal shares of the assistance during the past ten years have been provided in the form of equipment (40%) and expert services (37%), while the share of the training component was 23%. The best part of the resources was provided by the Technical Assistance and Co-operation Fund (96%), the remaining 4% was made available through assistance in kind. During the past ten years, project activities - and disbursements - have concentrated exclusively on three major areas: nuclear medicine (52%), general atomic energy development (25%) and agriculture (23%)

    In some parts of western Africa, Ebola treatment centers (ETCs) have reached capacity. Unless capacity is rapidly scaled up, the chance to avoid a generalized Ebola epidemic will soon diminish. The World Health Organization and partners are considering additional Ebola patient care options, including community care centers (CCCs), small, lightly staffed units that could be used to isolate patients outside the home and get them into care sooner than otherwise possible. Using a transmission model, we evaluated the benefits and risks of introducing CCCs into Sierra Leone's Western Area, where most ETCs are at capacity. We found that use of CCCs could lead to a decline in cases, even if virus transmission occurs between CCC patients and the community. However, to prevent CCC amplification of the epidemic, the risk of Ebola virus-negative persons being exposed to virus within CCCs would have to be offset by a reduction in community transmission resulting from CCC use.

  2. 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)

    Full Text Available The article analyses the viability of promoting crop-specific programs as a mean to improve smallholder net farm income and food security. The case study explores the relevance of European Union Stabilisation of Export Earnings (STABEX funds in supporting Sierra Leone’s agricultural development agenda. By analysing the drivers of food security for a number of targeted smallholders in the two most important agricultural zones of Sierra Leone, it is possible to compare the suitability of crop-specific support (in rice, cocoa and coffee versus general aid programs (public infrastructure, on and off farm diversification opportunities, sustainable practices, access to productive assets, etc.. The results indicate that crop diversification strategies are widespread and closely related to risk minimisation and enhanced food security among smallholders. Similarly, crop-specific programs mainly focusing on commercialisation tend to overlook important constraints associated to self-consumption and productivity.

    1989-01-01

    Pursuant to the discovery elsewhere of cosmogenic 10 Be in alluvial diamond fragments from Zaire, noble gas measurements were made on two identical splits of a finely powdered, harshly acid-washed sample derived from selected (for clarity) fragments of a single alluvial diamond from Sierra Leone (sample LJA → L4 and L5). Essentially identical results were obtained for both splits. Isotopic ratios for Ar, Kr, and Xe were atmospheric and their elemental abundances were high relative to published data, owing to shock implantation in the crushing as verified in a supplementary experiment. No neon was detected above blank level. 3 He was exceptionally abundant, 4 He exceptionally depleted, possibly from the acid wash, and the ratio 3 He/ 4 He almost unprecedentedly high at an R/R a value of 246 ± 16. The results support the hypothesis that excess 3 He in diamonds is cosmogenic, although a cosmic-ray exposure of 5, 35, or (impossibly) 152 Ma for cyclic gardening of the sample to a maximum depth of 0, 4.6 m, or 20 m, respectively, is required. Troublesome for the cosmogenic hypothesis is a sample from very deep in the Finsch mine, South Africa, found by Zadnik et al (1987) to have an R/R a value of 1,000. This paper includes histograms of noble gas data published prior to mid-1988 for diamonds of known provenance. The Sierra Leone diamond studied in the supplementary experiment belongs to a distinct population of 40* Ar-rich diamonds consisting mostly of cubic diamonds for Zaire

    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

    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.

    Full Text Available Fundamento: Los padecimientos crónicos y degenerativos son las primeras causas de morbi-mortalidad en México, por lo que el Sector Salud ha implementado acciones de prevención y detección oportuna. El uso de los servicios de salud es una conducta dinámica de la población. Para que la gente utilice estas acciones de prevención es necesario que se reduzcan barreras de acceso. Así, el objetivo del estudio fue determinar la utilización de los servicios de detección de diabetes mellitus, hipertensión arterial, cáncer cérvicouterino y mamario y aplicación del toxoide tetánico diftérico. Métodos: El tamaño de la muestra fue de 254 personas de 25 años y más, que habitaban en Monterrey y su zona metropolitana. En el uso de acciones preventivas se consideró a las personas que las habían usado el año anterior. El análisis consistió en estadística descriptiva y análisis bivariado. Resultados: Más del 60% de la población correspondió al sexo femenino, la edad promedio fue de 42,3 años±14 años y tres cuartas partes de la población contó con seguridad social. Un 37% mencionó haberse realizado la detección de diabetes y un 44,5% de hipertensión, mientras que le aplicaron el toxoide tetánico diftérico a un 31,1%. En las detecciones propias de la mujer, a un 34,3% de la población femenina le practicaron la correspondiente a cáncer cérvicouterino en tanto que a un 29,5%, la de cáncer mamario. No hubo relación entre uso de acciones con antecedentes familiares y percepción de importancia de la detección. Conclusiones: El uso de las acciones preventivas está por debajo de algunos estándares internacionales. Es necesaria la búsqueda de personas expuestas al riesgo para detectar oportunamente cualquier padecimiento crónico.

  13. XRD-based 40Ar/39Ar age correction for fine-grained illite, with application to folded carbonates in the Monterrey Salient (northern Mexico)

    2016-05-01

    Due to their minute size, 40Ar/39Ar analysis of illite faces significant analytical challenges, including mineral characterization and, especially, effects of grain size and crystallography on 39Ar recoil. Quantifying the effects of 39Ar recoil requires the use of sample vacuum encapsulation during irradiation, which permits the measurement of the fraction of recoiled 39Ar as well as the 39Ar and 40Ar∗ retained within illite crystals that are released during step heating. Total-Gas Ages (TGA) are calculated by using both recoiled and retained argon, which is functionally equivalent to K-Ar ages, while Retention Ages (RA) only involve retained Ar in the crystal. Natural applications have shown that TGA fits stratigraphic constraints of geological processes when the average illite crystallite thickness (ICT) is smaller than 10 nm, and that RA matches these constraints for ICTs larger than 50 nm. We propose a new age correction method that takes into account the average ICT and corresponding recoiled 39Ar for a sample, with X-ray Corrected Ages (XCA) lying between Total-Gas and Retention Ages depending on ICT. This correction is particularly useful in samples containing authigenic illite formed in the anchizone, with typical ICT values between 10 and 50 nm. In three samples containing authigenic illite from Cretaceous carbonates in the Monterrey Salient in northern Mexico, there is a range in TGAs among the different size-fractions of 46-49, 36-43 and 40-52 Ma, while RAs range from 54-64, 47-52 and 53-54 Ma, respectively. XCA calculations produce tighter age ranges for these samples of 52.5-56, 45.5-48.5 and 49-52.5 Ma, respectively. In an apparent age vs ICT or %2M 1illite plot, authigenic illite grains show a slope that is in general slightly positive for TGA, slightly negative for RA, but close to zero for XCA, with thinner crystallites showing more dispersion than thicker ones. In order to test if dispersion is due to a different formation history or the result

    Metabolic syndrome (MetS) is a major risk factor for cardiovascular disease and diabetes. Previous studies in obese children demonstrating a positive association between serum uric acid (sUA) and components of MetS are confounded by lack of uniformity in age and pubertal status of children. Therefore, we have examined the role of sUA in MetS and its components in pre-pubertal children (Tanner Stage I, age ≤ 9 years). Pre-pubertal obese children (32 boys, 27 girls, age 6-9 years) were recruited from Nuevo Leon, Mexico. For comparison, an equal number of children with normal body mass index (BMI) in the same age range (22 Boys, 39 girls, age 6-9 years) were also recruited from the same community. Presence of MetS and its components was defined according to the criteria of International Diabetes Federation. Fasting blood was analyzed for lipids, glucose, insulin, and uric acid. Among the obese children, sUA was positively associated with insulin resistance and hypertriglyceridemia and negatively associated with high density lipoprotein-cholesterol (HDLc). Subjects were three times more likely to have a MetS diagnosis per one unit (md/dL) difference in sUA. Of the 59 obese pre-pubertal children, 20 were classified as having MetS defined by the presence of abdominal obesity and two or more of other components described under methods. Of these, 57.1% (20/61) had sUA between 5.1 and 7.1 mg/dl. The findings of this study clearly indicate a positive relationship between uric acid and MetS and its components in pre-pubertal obese children with Tanner stage I and ≤9 years of age.

Sin embargo, la llegada de la Web 2.0, o lo que es lo mismo, la versión de Internet que permite que usuario y organizaciones interactúen, propició la aparición de una nueva forma de activismo, conocida como ciberactivismo, mediante la cual el usuario puede reivindicar, reprobar o denunciar todo aquello que la ONG defiende a través de Internet. Por otro lado, la aparición de las redes sociales, especialmente Facebook, también propició un nuevo ciberactivismo mediante el cual la ciudadanía podía intercambiar opiniones, denunciar hechos injustos o presionar a los poderes públicos. Por ello, muchas ONGs que hasta ese momento no se consideraban activistas, comenzaron a ofrecer a sus públicos un espacio en el que los mismos se convirtieran en protagonistas y parte activa de las causas por las que trabaja la organización.

    This work takes place into the Bierzo Region, located in northeast of the province of Leon (Spain). In this area numerous open-pit and underground coal mines exist. Some of them are still in activity but almost have been abandoned. In any case, mining implies the presence of coal adits, spoil dumps, tailing dams, and coal-washing plants at the river bank. Most of them persist when mining have finished. (Author)

    1993-02-01

    Based on foraminiferal and palynological high resolution studies, a set of Sequence Boundaries (SB) and Maximum Flooding Surfaces (MSF) were identified for the Venezuelan Northwestern Andean Foothills Leon and Chama formations. Changes in abundance patterns of forminifera palynomorphs, in faunal/floral composition and distribution, together with quantitative studies of particulate organic matter allowed picking SB 30, 21 and 15.5 (very low values of fossil abundance and faunal discontinuities, recognized by a rapid stratigraphic change in biofacies and faunal assemblage and the associated mineralogical contents) and MFS 18.5, 16, and 15 (abundant fossils). The Leon Formation represents coastal plain and swamp deposits with some minor fluctuations in the seawater level. The top of the Leon Formation shaly unit is bounded by SB 30, according to Hag B.U. et al (version 1992), marked by a decrease in fossil abundance. An increase in faunal/floral content close to the top of the section coincides with the MFS 18.5. The upper part of the formation is marked by a sandy unit with SB 16.5, characterized again by a decrease in fossil abundance at its top. The Chama Formation was deposited in a transitional environment, with minor seawater level fluctuations. Climate type was tropical humid, with seasonal precipitations, except at the Early Miocene arid or semiarid phase. Mangrove and rain forest vegetation dominated throughout the Early to Middle Miocene. MFS 16 was picked on the basis of a high abundance of microforams and glauconite.

    Travel restrictions were implementeded on an unprecedented scale in 2015 in Sierra Leone to contain and eliminate Ebola virus disease. However, the impact of epidemic travel restrictions on mobility itself remains difficult to measure with traditional methods. New 'big data' approaches using mobile phone data can provide, in near real-time, the type of information needed to guide and evaluate control measures. We analysed anonymous mobile phone call detail records (CDRs) from a leading operator in Sierra Leone between 20 March and 1 July in 2015. We used an anomaly detection algorithm to assess changes in travel during a national 'stay at home' lockdown from 27 to 29 March. To measure the magnitude of these changes and to assess effect modification by region and historical Ebola burden, we performed a time series analysis and a crossover analysis. Routinely collected mobile phone data revealed a dramatic reduction in human mobility during a 3-day lockdown in Sierra Leone. The number of individuals relocating between chiefdoms decreased by 31% within 15 km, by 46% for 15-30 km and by 76% for distances greater than 30 km. This effect was highly heterogeneous in space, with higher impact in regions with higher Ebola incidence. Travel quickly returned to normal patterns after the restrictions were lifted. The effects of travel restrictions on mobility can be large, targeted and measurable in near real-time. With appropriate anonymization protocols, mobile phone data should play a central role in guiding and monitoring interventions for epidemic containment.

La adopción de un nuevo paradigma en torno al medicamento –el uso racional del medicamento— no puede ser entendido únicamente como una respuesta a situaciones de crisis, cambios en el sistema político y/o la consolidación de ideas nuevas defendidas por activos emprendedores políticos. El análisis de la institucionalización de las relaciones de poder en torno a la política farmacéutica (o policy network es importante para explicar por qué los cambios en la política farmacéutica se producen de forma gradual como resultado de una negociación entre el Estado con la industria farmacéutica y las farmacias. Asimismo, se argumenta cómo la adopción de un paradigma nuevo en la política farmacéutica, se produce de forma paralela a un cambio en la estructura institucional de la política. En 2008 la política farmacéutica se gestiona a través de una red más abierta y plural, en la que los expertos tienen mayor peso en la toma de decisiones.

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

    Science.gov (United States)

    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

    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.

    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.

    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.

    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.

    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)

    1996-01-01

    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

    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.

    A rural paediatric hospital in Bo, Sierra Leone. To assess the level of adherence to standard treatment guidelines among clinicians prescribing treatment for children admitted with a diagnosis of malaria and/or lower respiratory tract infection (LRTI), and determine the association between (non) adherence and hospital outcomes, given that non-rational use of medicines is a serious global problem. Secondary analysis of routine programme data. Data were collected for 865 children admitted with an entry diagnosis of malaria and 690 children with LRTI during the period January to April 2011; some patients were classified in both categories. Non-adherence to guidelines comprised use of non-standard drug regimens, dosage variations, non-standard frequency of administration and treatment duration. Cumulative non-adherence to guidelines for LRTI cases was 86%. For malaria, this involved 12% of patients. Potentially harmful non-adherence was significantly associated with an unfavourable hospital outcome, both for malaria and for LRTI cases. Overall non-adherence to standard treatment guidelines by clinicians in a routine hospital setting is very high and influences hospital outcomes. This study advocates for the implementation of routine measures to monitor and improve rational drug use and the quality of clinical care in such hospitals.

    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.

    In 2012, the government of Sierra Leone cut the national budget allocation to the health sector. Civil society organizations planned a nationwide health budget advocacy campaign, coinciding with the 2012 general elections, to hold future leaders to account on financing for women's and children's health. As part of the campaign, Evidence for Action produced district health budget tracking scorecards. The scorecards presented Ministry of Finance data on the allocation and disbursement of health funds in each district. The data were communicated using simple, non-technical language so that citizens could understand the key messages and take action. A total of 5600 scorecards were shared at district electoral forums attended by political candidates, community members, and health activists. Since the election, the proportion of the total government budget allocated to health increased from 7.4% in 2012 to 11.2% in 2014. However, transforming politicians' commitments and pledges into implementation has been challenging, confirming that accountability is a long-term process.

    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.

    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 Palencia.

    Full Text Available The rhetorical device called “deceiving with the truth” (l. 319 et seq. described by Lope de Vega in the Arte Nuevo de hacer comedias has been misinterpreted ever since Morel Fatio confused it with another device mentioned by Lope a little earlier in the text (vv. 300-301, i. e. that of the need for a surprise ending. Later commentators such as H. Rennert and A. Castro, J. de José Prades, J. M. Rozas, F. Pedraza and J. Roso Díaz failed to interpret Lope’s verses correctly, despite the fact that G. T. Northrup (1929-1930 had already offered the keys to an appropriate interpretation. In the meantime, the procedure of “deceiving with the truth” has been unconvincingly identified in works such as La Celestina and dramatic texts of the sixteenth century. In order to confirm its long tradition, the article documents the device’s origin in Terence’s comedies and its use in the Middle Ages and in works such as Don Quixote.

    2004-07-01

    Full Text Available Hoy las organizaciones están cambiando drásticamente y adoptando nuevas formas de operación. Detrás de este fenómeno hay un compromiso con el rendimiento y con la creación de valores, que ha alterado profundamente la economía y la vida cotidiana. El principio de creación de valor estimula la tendencia de reemplazar la actual organización piramidal por un esquema de redes. El problema de fondo es cómo optimizar los recursos disponibles, y ello puede lograrse mediante un nuevo paradigma gerencial con redes de firmas interrelacionadas que maximizan la coordinación, la obtención de economías de escala y la explotación de sinergias. El objetivo de este artículo es describir este paradigma emergente que impone contar con estructuras flexibles que permitan la readaptación de las organizaciones. Por otra parte, la conclusión a que llegamos es que la generalización de los esquemas de redes explica que las sociedades avanzadas se articulan, cada vez más, en base a una lógica conexionista.

    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}.

    The scale and geographical distribution of the current outbreak in West Africa raised doubts as to the effectiveness of established methods of control. Ebola Virus Disease (EVD) was first detected in Sierra Leone in May 2014 in Kailahun district. Despite high case numbers elsewhere in the country, transmission was eliminated in the district by December 2014. We describe interventions underpinning successful EVD control in Kailahun and implications for EVD control in other areas. Internal service data and published reports from response agencies were analysed to describe the structure and type of response activities, EVD case numbers and epidemic characteristics. This included daily national situation reports and District-level data and reports of the Sierra Leone Ministry of Health and Sanitation, and Médecins Sans Frontières (MSF) patient data and internal epidemiological reports. We used EVD case definitions provided by the World Health Organisation over the course of the outbreak. Characteristics assessed included level of response activities and epidemiological features such as reported exposure (funeral-related or not), time interval between onset of illness and admission to the EVD Management Centre (EMC), work-related exposures (health worker or not) and mortality. We compared these characteristics between two time periods--June to July (the early period of response), and August to December (when coverage and quality of response had improved). A stochastic model was used to predict case numbers per generation with different numbers of beds and a varying percentage of community cases detected. There were 652 probable/confirmed EVD cases from June-December 2014 in Kailahun. An EMC providing patient care opened in June. By August 2014 an integrated detection, treatment, and prevention strategy was in place across the district catchment zone. From June-July to August-December 2014 surveillance and contact tracing staff increased from 1.0 to 8.8 per confirmed

    Full Text Available The Sierra Leone Demographic Health Survey 2008 found an HIV prevalence of 1.5%. This study investigates associations with HIV infection and HIV testing.Households were selected using stratified multi-stage sampling. In all selected households women aged 15-49 were eligible. In every second household men aged 15-59 were also eligible. Participants were asked to consent for anonymous HIV testing. All participants interviewed and tested were analysed. Multiple logistic regression identified associations with HIV infection, undiagnosed infection and with ever having a voluntary HIV test among sexually active participants.Of 7495 invited 86% (6,475 agreed to an interview and HIV test. Among 96 HIV positive participants, 78% had never taken a voluntary HIV test so were unaware of their serostatus, and 86% were sexually active in the last 12 months among whom 96% did not use a condom at last intercourse. 11% of all participants had previously voluntarily tested. Among women who had tested, 60% did so in antenatal care. We found that those living in an urban area, and those previously married, were more likely to be HIV infected. Voluntary HIV testing was more common in those aged 25-44, living in an urban area, females, having secondary or higher education, having first sexual intercourse at age 17 years or older, and using condoms at last sex. Although 82% of men and 69% of women had heard of HIV, only 35% and 29% respectively had heard of antiretroviral therapy.The HIV prevalence in Sierra Leone has been stable. HIV testing, however, is uncommon and most infected individuals are unaware of their serostatus. This could allow the epidemic to escalate as individuals with undiagnosed infection are unlikely to change their behaviour or access treatment. Improving knowledge and increasing testing need to remain central to HIV prevention interventions in Sierra Leone.

    The Tonkolili iron field in northern Sierra Leone has the largest known iron ore deposit in Africa. It occurs in a greenstone belt in an Achaean granitic basement. This study focused mainly on mapping areas with iron-oxide and hydroxyl bearing minerals, and identifying potential areas for haematite mineralization and banded iron formations (BIFs) in Tonkolili. The predominant mineral assemblage at the surface (laterite duricrust) of this iron field is haematitegoethite- limonite ±magnetite. The mineralization occurs in quartzitic banded ironstones, layered amphibolites, granites, schists and hornblendites. In this study, Crosta techniques were applied on Enhanced Thematic Mapper (ETM+) data to enhance areas with alteration minerals and target potential areas of haematite and BIF units in the Tonkolili iron field. Synthetic analysis shows that alteration zones mapped herein are consistent with the already discovered magnetite BIFs in Tonkolili. Based on the overlaps of the simplified geological map and the remote sensing-based alteration mineral maps obtained in this study, three new haematite prospects were inferred within, and one new haematite prospect was inferred outside the tenement boundary of the Tonkolili exploration license. As the primary iron mineral in Tonkolili is magnetite, the study concludes that, these haematite prospects could also be underlain by magnetite BIFs. This study also concludes that, the application of Crosta techniques on ETM+ data is effective not only in mapping iron-oxide and hydroxyl alterations but can also provide a basis for inferring areas of potential iron resources in Algoma-type banded iron formations (BIFs), such as those in the Tonkolili field.

  7. The Potential of Women’s Organization for Rural Development in Sierra Leone

    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

    Full Text Available Background. For most low- and middle-income countries, mental health remains a neglected area, despite the recognised burden associated with neuropsychiatric conditions and the inextricable link to other public health priorities. Objectives. To describe the results of a free outpatient mental health programme delivered by non-specialist health workers in Makeni, Sierra Leone between July 2008 and May 2012.  Methods. A nurse and two counsellors completed an 8-week training course focused on the identification and management of seven priority conditions: psychosis, bipolar disorder, depression, mental disorders due to medical conditions, developmental and behavioural disorders, alcohol and drug use disorders, and dementia. The World Health Organization recommendations on basic mental healthcare packages were followed to establish treatment for each condition.  Results. A total of 549 patients was assessed and diagnosed as suffering from psychotic disorders (n=295, 53.7%, manic episodes (n=69, 12.5%, depressive episodes (n=53, 9.6%, drug use disorders (n=182, 33.1%, dementia (n=30, 5.4%, mental disorders due to medical conditions (n=39, 7.1%, and developmental disorders (n=46, 8.3%. Of these, 417 patients received pharmacological therapy and 70.7% were rated as much or very much improved. Of those who could not be offered medication, 93.4% dropped out of the programme after the first visit.  Conclusions. The identification and treatment of mental disorders must be considered an urgent public health priority in low- and middle-income countries. Trained primary health workers can deliver safe and effective treatment for mental disorders as a feasible alternative to ease the scarcity of mental health specialists in developing countries.

    Three public health projects in Uganda and Sierra Leone are used to illustrate a new approach to construction of health buildings in villages. Emphasis is placed on community involvement. The health projects were comprehensive and relied on health education, employment of local village health workers, and establishment of village health committees. The objective of community involvement was described as encouragement of people to change their own diets and living conditions. This approach to primary health care is considered to be a strong basis for sustainable social development. Each of the three communities initiated the building projects slightly differently. There was a range of structures: traditional meeting halls, simple rooms with imported materials and a pit latrine, new buildings combining local and imported materials and labor, new nontraditional buildings, rehabilitated existing nontraditional buildings with imported labor and materials, and temporary mobile clinics. Community involvement was at different levels. All three projects were the result of a combined effort of national governments or mission hospitals, nongovernmental organizations, and the host community. The following should be considered before beginning construction: a suitable site, appropriate staff accommodation, the likely motivation of the host community, seasonality, local materials available, availability of skilled labor, and design. A plan of work during construction should include a building design, site supervision, transportation of local and non-local materials, unskilled labor, and skilled labor. Village health committees with or without government help would be responsible for maintenance of buildings after construction. A key feature of this approach is the assessment of the community's ability and capacity to contribute.

    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.

    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 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

    As construction and building material, natural stone has a great potential to promote the commercial activities of certain European regions. Such is the case of Castilla y Leon in Spain, where many different rocks, ranging from sedimentary to metamorphic and igneous, are commercialized for building purposes. However, to be able to compete in a market subject to an economic crisis, highly exacerbated in the construction sector, and to compete with the lower prices offered by emerging countries, the issue would be to make the Spanish offer more attractive. Here we propose a complete characterization of rocks regarding their radiological properties, which are related to their mineralogy and geochemistry. Rocks emit natural radioactivity, and the presence of Rn and its decay products in dwellings has become an important issue in North America and Europe owing to its relationship with the carcinogenic effects of this gas. Although most of the studied rocks comply with the I parameter proposed in the European Norm 112 for Radiological Protection (accepted value I ≤ 1; average for sedimentary rock: I = 0.22, SD 0.14; average for metamorphic rocks: I = 0.70, SD 0.48; average for igneous rock: I = 0.86, SD 0.22), the inclusion of a proper radiological characterization in the list of characteristics would guarantee quality and safety in their use in comparison with products lacking this information. Some natural stones have been demonized for the potential exhalation of natural radioactivity, and the different parameters used should be addressed in a more systematic way.

    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.

    Youth in war-affected regions are at risk for poor psychological, social, and educational outcomes. Effective interventions are needed to improve mental health, social behavior, and school functioning. This randomized controlled trial tested the effectiveness of a 10-session cognitive-behavioral therapy (CBT)-based group mental health intervention for multisymptomatic war-affected youth (aged 15-24 years) in Sierra Leone. War-affected youth identified by elevated distress and impairment via community screening were randomized (stratified by sex and age) to the Youth Readiness Intervention (YRI) (n = 222) or to a control condition (n = 214). After treatment, youth were again randomized and offered an education subsidy immediately (n = 220) or waitlisted (n = 216). Emotion regulation, psychological distress, prosocial attitudes/behaviors, social support, functional impairment, and posttraumatic stress disorder (PTSD) symptoms were assessed at pre- and postintervention and at 6-month follow-up. For youth in school, enrollment, attendance, and classroom performance were assessed after 8 months. Linear mixed-effects regressions evaluated outcomes. The YRI showed significant postintervention effects on emotion regulation, prosocial attitudes/behaviors, social support, and reduced functional impairment, and significant follow-up effects on school enrollment, school attendance, and classroom behavior. In contrast, education subsidy was associated with better attendance but had no effect on mental health or functioning, school retention, or classroom behavior. Interactions between education subsidy and YRI were not significant. YRI produced acute improvements in mental health and functioning as well as longer-term effects on school engagement and behavior, suggesting potential to prepare war-affected youth for educational and other opportunities.

Desarrollo: Los factores de riesgo son aquellos signos biológicos o hábitos adquiridos que se presentan con mayor frecuencia en los pacientes con una enfermedad concreta. La enfermedad cardiovascular arterioesclerótica tiene un origen multifactorial y los factores clásicos o tradicionales se dividen en 2 grandes grupos: no modificables como la edad, sexo y antecedentes familiares, y modificables como dislipidemia, tabaquismo, diabetes, hipertensión arterial, obesidad y sedentarismo. El concepto de nuevos factores predictores de riesgo cardiovascular, identificados a partir de la investigación etiopatogénica de la arterioesclerosis y respaldado en observaciones clínicas, epidemiológicas y de laboratorio, han sido considerados en la actualidad, predictores de riesgo independiente, entre los más estudiados tenemos: Homocisteína (HCy; Fibrinógeno; Ácido Úrico; Proteína C reactiva e Infecciones. Conclusiones: Los factores de riesgo tradicionales como el tabaquismo, el colesterol elevado, la obesidad y el sedentarismo, se relacionan con un mayor riesgo de enfermedad cardiovascular arterioesclerótica; sin embargo, muchas personas con aparente bajo riesgo, sufren ataques cardíacos. Se ha analizado la importancia en el desarrollo de la enfermedad arterioesclerótica la elevación de los valores en sangre de homocisteina, fibrinógeno, ácido úrico, proteína C reactiva y la relación con agentes infecciosos. Varios de estos factores son considerados en la actualidad, predictores de riesgo independiente.

    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

    We developed an agent-based model to investigate the epidemic dynamics of Ebola virus disease (EVD) in Liberia and Sierra Leone from May 27 to December 21, 2014. The dynamics of the agent-based simulator evolve on small-world transmission networks of sizes equal to the population of each country, with adjustable densities to account for the effects of public health intervention policies and individual behavioral responses to the evolving epidemic. Based on time series of the official case counts from the World Health Organization (WHO), we provide estimates for key epidemiological variables by employing the so-called Equation-Free approach. The underlying transmission networks were characterized by rather random structures in the two countries with densities decreasing by ~19% from the early (May 27-early August) to the last period (mid October-December 21). Our estimates for the values of key epidemiological variables, such as the mean time to death, recovery and the case fatality rate, are very close to the ones reported by the WHO Ebola response team during the early period of the epidemic (until September 14) that were calculated based on clinical data. Specifically, regarding the effective reproductive number Re, our analysis suggests that until mid October, Re was above 2.3 in both countries; from mid October to December 21, Re dropped well below unity in Liberia, indicating a saturation of the epidemic, while in Sierra Leone it was around 1.9, indicating an ongoing epidemic. Accordingly, a ten-week projection from December 21 estimated that the epidemic will fade out in Liberia in early March; in contrast, our results flashed a note of caution for Sierra Leone since the cumulative number of cases could reach as high as 18,000, and the number of deaths might exceed 5,000, by early March 2015. However, by processing the reported data of the very last period (December 21, 2014-January 18, 2015), we obtained more optimistic estimates indicative of a remission of

Nanomaterials are a new alternative to successfully treat the multiresistant microorganisms. Nanostructured materials are used in many fields, including biological sciences and medicine. Recently, it was demonstrated that the bactericidal activity of zero-valent bismuth colloidal nanoparticles inhibited the growth of Streptococcus mutans; however the antimycotic potential of bismuth nanostructured derivatives has not yet been studied. The main objective of this investigation was to analyze the fungicidal activity of bismuth oxide nanoparticles against Candida albicans, and their antibiofilm capabilities. Our results showed that aqueous colloidal bismuth oxide nanoparticles displayed antimicrobial activity against C. albicans growth (reducing colony size by 85% and a complete inhibition of biofilm formation. These results are better than those obtained with chlorhexidine, nystatin, and terbinafine, the most effective oral antiseptic and commercial antifungal agents. In this work, we also compared the antimycotic activities of bulk bismuth oxide and bismuth nitrate, the precursor metallic salt. These results suggest that bismuth oxide colloidal nanoparticles could be a very interesting candidate as a fungicidal agent to be incorporated into an oral antiseptic. Additionally, we determined the minimum inhibitory concentration for the synthesized

    We compiled a check list of the herpetofauna of Nuevo León. We documented 132 species (23 amphibians, 109 reptiles), representing 30 families (11 amphibians, 19 reptiles) and 73 genera (17 amphibians, 56 reptiles). Only two species are endemic to Nuevo León. Nuevo León contains a relatively high richness of lizards in the genus Sceloporus. Overlap in the herpetofauna of Nuevo León and states it borders is fairly extensive. Of 130 native species, 102 are considered species of Least Concern in the IUCN red list, four are listed as Vulnerable, five are listed as Near Threatened, and four are listed as Endangered. According to SEMARNAT, 78 species are not of conservation concern, 25 are subject to Special Protection, 27 are Threatened, and none are listed as in Danger of Extinction. Given current threats to the herpetofauna, additional efforts to understand the ecology and status of populations in Nuevo León are needed.

    Full Text Available Los entornos digitales cada vez son más comunes en la enseñanza de lenguas extranjeras, además de jugar un papel muy importante como organizadores de tareas, proveedores de input y como gestores de recursos para la enseñanza de idiomas. Permiten, asimismo, a los profesores organizar la interacción de los estudiantes y, al mismo tiempo, proporcionar un magnífico entorno para presentar distintos géneros informativos. Las wikis son hoy en día una de las redes sociales que cada vez se utilizan más para dar apoyo al aprendizaje cooperativo y para fomentar el aprendizaje autónomo. Están estrechamente relacionadas con las metodologías docentes que se basan en el desarrollo de un proyecto o en la resolución de problemas, prácticas docentes éstas en las que tanto alumnos como profesores contribuyen a la construcción del conocimiento y comparten experiencias. Las wikis también han contribuido a crear las llamadas "comunidades de práctica", a las que pueden acudir los estudiantes en contextos de autoaprendizaje o en aquellas situaciones donde se carece del apoyo de un tutor o profesor para encontrar apoyo y consejo. Añadido a esto, la proliferación de herramientas que fomentan la comunicación mediatizada por ordenador han multiplicado los métodos docentes que se aplican en el aula y fuera de ella y han tenido una influencia muy significativa en el surgimiento de un nuevo perfil de estudiante; es decir, aquél que está plenamente acostumbrado a utilizar estas herramientas para relacionarse socialmente con otras personas aunque no sea con fines educativos. Por último, mediante el uso de las wikis se ha desarrollado el concepto de "enseñanza entre pares" y "tutorización entre pares", especialmente en contextos de creación de textos escritos mediante la cooperación colectiva. Este hecho ha contribuido, asimismo, a que el estudiante tenga mayor conciencia de los procesos implícitos en la construcción y edición textual. Este cap

Nos preguntamos qué nuevos problemas introduce su puesta en uso, propiciada desde organismos y autores prestigiosos: cuando se habla de "educabilidad" se mira al niño y se culpabiliza a su familia, pero se dejan entre paréntesis las prácticas pedagógicas y los contextos escolares en que suceden los éxitos y fracasos; en el plano conceptual, se racializa el concepto de cultura o se supone la transmisión intergeneracional de la pobreza. La tramposa transformación de una problemática colectiva, vinculada con las condiciones sociales de desigualdad, en una problemática individual hace posible que se proponga la búsqueda de "resilientes" (aquellos que muestren condiciones que les permiten resistir los problemas de su medio. De este modo, se oculta el origen social de las problemáticas singulares.In this article, we explore two concepts widely used today in educational milieux: "educability" (why education isn't equally successfull with every children and "resilience" (which explains the reasons for differences: some people, in adversity -social or familial violence- or poverty, "go ahead" while others, in the same situations, fail to do so.

    Full Text Available En la actualidad las enfermedades cardiovasculares son la principal causa de muerte en los países industrializados y para 2020, lo serán en países en vía de desarrollo. El síndrome coronario agudo se caracteriza por la ruptura o erosión de una placa aterosclerótica que trae consigo grados variables de trombosis y embolización distal, que llevan a una disminución en la perfusión miocárdica. Posterior a la disrupción vascular, empieza un proceso de agregación, activación y adhesión plaquetaria que inicia la formación del trombo mural. Dado que el primer paso en la formación del trombo coronario involucra la activación y la agregación plaquetaria, el tratamiento con medicamentos antiplaquetarios es una de las piedras angulares del síndrome coronario agudo. La antiagregación dual con ácido acetil salicílico y un inhibidor del receptor P2Y12, hacen parte del manejo actual de los pacientes con síndrome coronario agudo y de aquellos sometidos a intervención coronaria percutánea. El clopidogrel es el inhibidor del receptor P2Y12 más utilizado; sin embargo, sus beneficios clínicos se ven limitados por varios factores que interfieren con la conversión del medicamento a su metabolito activo. Es por esto que recientemente se han desarrollado nuevos inhibidores del receptor P2Y12, como prasugrel y ticagrelor, con un efecto antiplaquetario más potente y mayores beneficios clínicos. Las actualizaciones recientes de las guías de manejo basadas en la evidencia los han incluido como parte del tratamiento de esta patología con un grado de recomendación incluso mayor que el de clopidogrel.

    2017-12-01

    The outbreak of Ebola virus disease in Guinea, Liberia, and Sierra Leone was the largest epidemic of Ebola ever recorded. The healthcare workforce was diminished and exhausted as the region emerged from civil war. Few qualitative, descriptive studies have been conducted to date that concentrate on the voices of Ebola survivors and their perceptions of health messages. In this study, we employed an interpretive, qualitative design to explore participant experiences. Twenty five survivors who had recovered from Ebola were recruited from three villages in Liberia and Sierra Leone in August 2015. Data were collected using semistructured interviews. Data analysis revealed four themes: (i) degrees of mistrust; (ii) messages conflicting with life and culture; (iii) seeing is believing; and (iv) recovery inspires hope. The findings were explored in the context of the relevant literature. The themes highlight the need to develop culturally-appropriate messages, underpinned by a sound understanding of the community and a willingness to work with the culture and trusted leaders. © 2017 John Wiley & Sons Australia, Ltd.

    2014-01-01

    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.

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.

The honest and efficient application of the public resources is a permanent government task, because it derives in a large part the welfare of society and thereby strengthens confidence in public institutions. If the public resources are not well applied, represents the bad part of the society called corruption. One of the most ancient problems that has affected the humanity is precisely the corruption, because it undermines the legitimacy of the public institutions, attempts against the society, the justice, the ethics, the moral order and the nation integral growth. The corruption attempts against the sustainable development and the law mandate and diminish the trust of the citizens and government dependencies and the own activity of public service.

    1994-01-01

    This book collects the contributions for a meeting in October 1991 in Naples under the auspices of the Istituto Italiano per gli Studi Filosofici to commemorate the life and scientific achievements of Leon Van Hove, distinguished theorist and CERN Research Director General from 1976-80, who died in 1990. The articles span Van Hove's scientific contributions and his involvement in European scientific policy and education. His early scientific work, with contributions to mathematics, statistical mechanics and neutron physics, is covered by A. Messiah and L. Michel, with an appraisal by A. Martin. Among Van Hove's best known research papers is his analysis of neutron scattering data to explore the structure of dense systems and magnetic materials in terms of pair correlation functions. This and its later applications are reviewed by A. Messiah, who also collects some interesting memorabilia from the years they spent together at Princeton, where Van Hove also had a fruitful collaboration with G. Placzek. L. Michel undertakes the task of explaining in its full generality the predictions of Van Hove singularities in the phonon dispersion relation for periodic systems. The functional relation between the frequency and wave vector characterizing elastic waves in crystals plays a central role in the explanation of their thermodynamic, acoustic and optical properties. The existence of these singularities was a consequence of applying a beautiful mathematical theory of M. Morse to physics. Van Hove derived his results by showing that they were inevitable consequences of the global topology of the first Brillouin zone of the periodic lattice. This pioneer work used powerful global analysis techniques to unravel concrete physical properties. For this impressive body of achievement, together with his study of low dimensional phase transitions and non-equilibrium statistical mechanics, he was awarded the prestigious Danny Heinemann Prize of the American Physical Society

    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.

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 objective of this project is to study the willingness to pay (WTP) for health insurance (HI) of individuals working in the informal sector in Sierra Leone, using a purposely-designed survey of a representative sample of this sector. We elicit the WTP using the Double-Bounded Dichotomous Choice with Follow Up method. We also examine the factors that are positively and negatively associated with the likelihood of the respondents to answer affirmatively to joining a HI scheme and to paying three different possible premiums, to join the HI scheme. We additionally analyze the individual and household characteristics associated with the maximum amount the household is willing to pay to join the HI scheme. The results indicate that the average WTP for the HI is 20,237.16 SLL (3.6 USD) per adult but it ranges from about 14,000 SLL (2.5 USD) to about 35,000 SLL (6.2 USD) depending on region, occupation, household and respondent characteristics. The analysis of the maximum WTP indicates that living outside the Western region and working in farming instead of petty trade are associated with a decrease in the maximum premium respondents are WTP for the HI scheme. Instead, the maximum WTP is positively associated to being a driver or a biker; having secondary or tertiary education (as opposed to not having any); the number of pregnant women in the household; having a TV; and, having paid for the last medical requirement. In summary, the various analyses show that a premium for the HI package could be set at approximately 20,000 SLL (3.54 USD) but also that establishing a single premium for all individuals in the informal sector could be risky. The efficient functioning of a HI scheme relies on covering as much of the population as possible, in order to spread risks and make the scheme viable. The impact of the various population characteristics raises the issue of how to rate premiums. In other words, setting a premium that may be too high for a big proportion of the

    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.

    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.

    Full Text Available El concepto de turismo residencial evoluciona desde su apreciación convencional con motivaciones parecidas al turismo de masas tradicional hacia una nueva aceptación que implica la creación de nuevos espacios de ocio alejados de sus territorios de origen. En esta nueva aceptación, que implica una alta movilidad humana residencial, es básica la búsqueda de un estilo de vida en la que es importante la autorrealización personal y un deseo de una mejor calidad de vida. Así el turismo residencial se conforma como una manifestación de los nuevos comportamientos turísticos en el siglo XXI.

    Full Text Available El nuevo y polémico régimen fiscal de operaciones vinculadas supone un cambio radical respecto de la regulación anterior a la Ley de Prevención del Fraude Fiscal de 2006, y pretende aproximar la normativa fiscal a los criterios expresados por las directrices de la OCDE sobre precios de transferencia, y a la nueva normativa contable, que se inspira en las Normas Internacionales de Contabilidad asumidas por la Unión Europea. Los principales cambios han afectado no solo al concepto de partes vinculadas (que se ha ampliado o la incorporación de los métodos de valoración de la OCDE, sino, sobre todo a: 1.La creación de una nueva obligación de documentación a cargo del obligado tributario que tiene que valorar sus operaciones a valor de mercado; 2.La creación de dos nuevas infracciones tributarias, para asegurar el cumplimiento de la obligación de documentación; 3.La simplificación del procedimiento de comprobación del valor normal de mercado; 4.La regulación expresa del denominado ajuste secundario. Pese a su novedad y por las presiones de los afectados, se han producido reformas para rebajar tanto las obligaciones de documentación como las sanciones, y, todo hace pensar que dado el contexto de crisis económica, puedan producirse más. The new and polemic fiscal regime of linked operations a radical change supposes respect of the regulation previous to the Law of Prevention of the Tax evasion of 2006, and tries to bring the fiscal regulation near to the criteria expressed by the directives of the OECD on prices of transfer, and to the new countable regulation, which inspires by the International Procedure of Accounting assumed by the European Union.

  18. Estimating the future number of cases in the Ebola epidemic--Liberia and Sierra Leone, 2014-2015.

    The first cases of the current West African epidemic of Ebola virus disease (hereafter referred to as Ebola) were reported on March 22, 2014, with a report of 49 cases in Guinea. By August 31, 2014, a total of 3,685 probable, confirmed, and suspected cases in West Africa had been reported. To aid in planning for additional disease-control efforts, CDC constructed a modeling tool called EbolaResponse to provide estimates of the potential number of future cases. If trends continue without scale-up of effective interventions, by September 30, 2014, Sierra Leone and Liberia will have a total of approximately 8,000 Ebola cases. A potential underreporting correction factor of 2.5 also was calculated. Using this correction factor, the model estimates that approximately 21,000 total cases will have occurred in Liberia and Sierra Leone by September 30, 2014. Reported cases in Liberia are doubling every 15-20 days, and those in Sierra Leone are doubling every 30-40 days. The EbolaResponse modeling tool also was used to estimate how control and prevention interventions can slow and eventually stop the epidemic. In a hypothetical scenario, the epidemic begins to decrease and eventually end if approximately 70% of persons with Ebola are in medical care facilities or Ebola treatment units (ETUs) or, when these settings are at capacity, in a non-ETU setting such that there is a reduced risk for disease transmission (including safe burial when needed). In another hypothetical scenario, every 30-day delay in increasing the percentage of patients in ETUs to 70% was associated with an approximate tripling in the number of daily cases that occur at the peak of the epidemic (however, the epidemic still eventually ends). Officials have developed a plan to rapidly increase ETU capacities and also are developing innovative methods that can be quickly scaled up to isolate patients in non-ETU settings in a way that can help disrupt Ebola transmission in communities.

    In low- and middle-income countries, a shortage of properly trained, supervised, motivated and equitably distributed health workers often hinder the delivery of lifesaving interventions. Various health workforce bottlenecks can be addressed by tackling well-being and interpersonal relationships of health workers with their colleagues and clients. This paper uses data from the Helping Health Workers Cope (HHWC) project in a rural district of Sierra Leone to achieve three objectives. First, we describe the effect of counseling and psychosocial training on coping skills, stress levels, and provider-provider and provider-client relationships. Second, we examine whether a change in coping skills is associated with a change in relationships. Finally, we qualitatively identify key ways through which the uptake of coping skills is linked to a change in relationships. The HHWC project was implemented from February 2012 to June 2013 in Kono district in the Eastern province of Sierra Leone, with the neighboring district of Tonkolili selected as the control site. The evaluation followed a mixed-methods approach, which included a quantitative survey, in-depth interviews and focus group discussions with health workers and clients. Mean values of the variables of interest were compared across sub-populations, and correlation analyses were performed between changes in coping skills, stress levels, and changes in relationships. Overall, the results demonstrate that the HHWC intervention had a positive effect on coping skills, stress levels and provider-provider and provider-client relationships. Furthermore, associations were observed between changes in coping skills and changes in relationships as well as changes in stress management skills and changes in relationships. Psychosocial education can have major impacts on health worker well-being and the quality of health care delivery. Integrating psychosocial counseling and training interventions into health worker pre-service and

    Background A national baseline mapping of schistosomiasis and soil-transmitted helminthiasis (STH) was performed in Sierra Leone. The aim was to provide necessary tools for the Ministry of Health and Sanitation to plan the intervention strategies in the national integrated control program on neglected tropical diseases according to the World Health Organization (WHO) guidelines for preventative chemotherapy (PCT) and for future monitoring and evaluation. Methodology/Principal Findings 53 primary schools were randomly selected through a two-staged random sampling throughout the country. Approximately one hundred children aged 5–16 years of age were systematically selected from each school and their stool samples examined in a field laboratory. A total of 5,651 samples were examined. Data were analyzed with multivariable logistic regression models using model-based geostatistics. Spatial analysis predicted that S. mansoni infection was positively associated with population density and elevation and that there was a large cluster of high risk of S. mansoni infection (prevalence >70%) in the north and most of the eastern areas of the country, in line with the observed prevalence in Kono (63.8–78.3%), Koinadugu (21.6–82.1%), Kailahun (43.5–52.6%), Kenema (6.1–68.9%) and Tonkolili (0–57.3%). Hookworm infection was negatively associated with population density and land surface temperature, and was high across Sierra Leone with a large cluster of high infection risk (prevalence >70%) in the north-eastern part of the country. Remarkably low prevalence of Ascaris lumbricoides (7.2%) and Trichuris trichiura (3.3%) was recorded when compared with results published in the 1990s. Conclusions/Significance Results justify PCT for schistosomiasis for school age children and at-risk adults every year in high-risk communities in five districts and every two years in moderate-risk communities in one more district. The high prevalence of STH, particularly hookworm, coupled

    Full Text Available Background: There is a dearth of skilled pharmaceutical workforce in the African region, and this is partly due to a limited number of prospective students entering the profession. An understanding of the factors that influence the choice of pharmacy as a career is needed to attract highly motivated and skilled individuals into the profession. Therefore, the objective of this study was to assess pharmacy students’ motivation to study pharmacy, their attitude and future career intentions in Sierra Leone. Methods: A cross-sectional questionnaire-based survey of undergraduate pharmacy students enrolled at the College of Medicine, and Allied Health Sciences, University of Sierra Leone (COMAHS – USL was carried out between May and June 2015. Descriptive statistics, as well as chi-square and Fisher exact two-tailed tests were used to analyze the data. Results: Close to a quarter (24.3% of pharmacy students surveyed chose pharmacy as their preferred major. The choice of pharmacy as a preferred major was common among first-year students, (p=0.001, those who were married (p<0.001 and have had pharmacy practice experience (p<0.001. Motivation for choosing pharmacy was assessed based on three domains (education, personal and career-related factors.Students cited a subject teacher at school ̸ College (66.7% as the most education-related influence, while friends and family members (61.1% was the major personal-related factor. Also, students considered the desire for self-employment in a healthcare related job (27.8%, and excellent career opportunities (27.8% as the major career-related factors that influenced their choice of pharmacy as a preferred major. Medicine was the first choice of study among the majority (95% of students that chose pharmacy as a second choice when seeking admission into the university. Pharmacy students demonstrated a positive attitude toward the profession, and considered drug manufacturing (47.3% and hospital pharmacy (43

    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)

OSORNOPHRYNE is proposed as a new genus, characterized mainly by external, osteologicaland myological features, with O. percrassa, sp, nov. (loc. typ.: Páramo de Herveo, Tolima, Colombia as type species, and O. bufoniformis, comb. nov. (= Atelopus bufoniformis PERACCA,1904 from the Andes of southern Colombia and northern Ecuador, as a referred species. The functional and adaptative significance of the main characters is discussed indetail. It is concluded that the genus presents several primitive characters of remarkable interest, i.a. the inguinal amplexus, previously unknownin the family, which strengthens the thesis that the Bufonidae are derived from the Leptodactylidae, as well as several other highly especialized skeletal and myological features (i. a . a total number of 6 presacral vertebrae, only  shared by two other recent anuran genera: Hymenochirus [Pipidae] and Oreophrynella [Bufonidae]. It is concluded also thatOsornophryne, although shows several remarkable phenetic similitudes with Oreophrynella (monotypic endemic genus of the Mount Roraima, Bolivar, Venezuela, such similitudes are due to an extraordinary instance of evolutionary convergence. Osornophryne is regarded as a genus probablyderived from the same encestral phyletic line that gives origin to Atelopus, invading the high Andean "páramos", specializing and acquiring by adaptative paralellism several resemblances, such as the "bufonoid" aspect, with the high Andean species of Atelopus.Se plantea una breve reseña del historial taxonómico de los "Atelopodidae" concluyendo que el grupo debe incluirse dentro de la familia Bufonidae ratificando la opinión de autores recientes.

    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.

    2015-12-01

    Full Text Available El objetivo de este trabajo es analizar la relación entre la orientación internacional y la supervivencia de empresas manufactureras de reciente creación. Para ello se estudió una muestra de 2.975 nuevos emprendimientos constituidos durante el período 2001-2010 en la industria textil-confección de España. Metodológicamente, se han empleado modelos de duración mediante regresiones de Cox, que modelizan el riesgo relativo asociado con una variable en función del tiempo transcurrido hasta que sucede el evento. Los principales resultados evidencian que la internacionalización de los nuevos emprendimientos es una condición necesaria aunque no suficiente para sobrevivir en una industria globalizada como la textil-confección. Los nuevos emprendimientos manufactureros compitiendo en sectores de alto valor añadido tienen un menor riesgo relativo de mortalidad que las empresas que compiten en sectores de bajo valor añadido. Por ello, junto con esa orientación hacia los mercados exteriores, es necesario que estos emprendimientos consideren otros retos relacionados con el ajuste en el binomio modalidad internacionalizadora y subsector de actividad en el que desean competir, definido este en términos de valor añadido. Futuras investigaciones deben profundizar en la posible existencia de un momento óptimo para internacionalizarse en términos de edad organizativa porque en los nuevos emprendimientos manufactureros parece existir una relación de intercambio entre internacionalización temprana y supervivencia en el corto plazo. No obstante, si el nuevo emprendimiento permanece demasiado tiempo como puramente doméstica tiene el riesgo de quedarse estancado en dicho mercado y no aprovechar las oportunidades de los mercados exteriores de compra y/o venta

    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.

    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

    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.

    Full Text Available BACKGROUND: A national mapping of Schistosoma haematobium was conducted in Sierra Leone before the mass drug administration (MDA with praziquantel. Together with the separate mapping of S. mansoni and soil-transmitted helminths, the national control programme was able to plan the MDA strategies according to the World Health Organization guidelines for preventive chemotherapy for these diseases. METHODOLOGY/PRINCIPAL FINDINGS: A total of 52 sites/schools were selected according to prior knowledge of S. haematobium endemicity taking into account a good spatial coverage within each district, and a total of 2293 children aged 9-14 years were examined. Spatial analysis showed that S. haematobium is heterogeneously distributed in the country with significant spatial clustering in the central and eastern regions of the country, most prevalent in Bo (24.6% and 8.79 eggs/10 ml, Koinadugu (20.4% and 3.53 eggs/10 ml and Kono (25.3% and 7.91 eggs/10 ml districts. By combining this map with the previously reported maps on intestinal schistosomiasis using a simple probabilistic model, the combined schistosomiasis prevalence map highlights the presence of high-risk communities in an extensive area in the northeastern half of the country. By further combining the hookworm prevalence map, the at-risk population of school-age children requiring integrated schistosomiasis/soil-transmitted helminth treatment regimens according to the coendemicity was estimated. CONCLUSIONS/SIGNIFICANCE: The first comprehensive national mapping of urogenital schistosomiasis in Sierra Leone was conducted. Using a new method for calculating the combined prevalence of schistosomiasis using estimates from two separate surveys, we provided a robust coendemicity mapping for overall urogenital and intestinal schistosomiasis. We also produced a coendemicity map of schistosomiasis and hookworm. These coendemicity maps can be used to guide the decision making for MDA strategies in combination

    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.

    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

    Full Text Available Reactive oxygen species (ROS play a key role in oxidative stress processes at the biological level. In most cases the presence of these chemical species is undesirable due to the impact they have on tissues and cellular structures, however, their effects can be used to control the incidence of microorganisms responsible for deterioration processes in fruits and vegetables. In the present study the feasibility of combining low temperature storage with the presence of reactive oxygen species generated using Oxyion® technology to control the deterioration process in strawberry (Fragaria X ananassa was studied. The treatments used were as follows: control storage (4°C ± 2°C without Oxyion® and ROS storage (4°C ± 2°C with Oxyion®, for two product categories according to weight and maturation state according to NTC 4103 (ICONTEC, 1997. The variables were monitored with measuring points at 1, 3, 5, 7, 10 and 15 days after harvest in percentage of loss of mass, soluble solids, respiratory intensity, acidity, resistance, color and ethylene and significant interactions among variables. At the conclusion of the study, Oxyion® technology was found to have statistically significant differences compared to control, and have allowed to less weight loss, higher resistance and lower exogenous ethylene production, extending the life of strawberry cv. Monterrey in a 40% during storage, additionally the losses by action of microorganisms present in strawberries surface were reduced considerably, generating a positive precedent in the processes of storage and conservation of fruits for Colombia.

    The concentration levels of trace metals of toxicological importance were evaluated in the total suspended particles (TSP) and particulate matter smaller than 2.5 μm (PM2.5) collected in the Metropolitan Area of Monterrey (MAM) in Mexico. Samples were characterized by inductively coupled plasma atomic emission spectroscopy (ICP-AES), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy with an energy-dispersive spectroscopy system (SEM-EDS). In addition, the data were statistically treated by the methodology of Pearson Correlation (PC) and Principal Components Analysis (PCA) to identify the possible emitting sources. Surface analysis of the particulate matter (PM) by XPS revealed that the most abundant elements were Ca, Al, Na, Zn, Cu and Mg. The deconvolution of the Ca2p, Zn2p and Cu2p signals showed that the main contributors were CaCO3, ZnO and Cu/Cu2O, respectively. The bulk analysis of the PM by ICP-AES showed Fe, Cu and Zn as the most abundant elements. Fe-rich particles presented two different morphologies: the prismatic particles were associated with a natural origin, while the spherical particles with anthropogenic sources. The Zn and Cu were predominantly observed in the sampling stations with high vehicular traffic, and the emitting sources were associated with the burning of fuels from automobiles and the wear of the tires and brakes. The highest concentration of Pb was detected in the sampling station located near the industrial zones, and its cause was associated with the ceramic and glass industries, the burning of fuel oil in power plants and the production of lead-based batteries for automobiles.
