Sistema de apoyo a la toma de decisiones para la selección de especies forrajeras (STDF) en función de la oferta ambiental en Colombia

Low food supply is a major problem affecting a large percentage of the livestock population in Colombia and is largely associated to inappropriate choice of forage species; and thus not well adapted to the environmental conditions of a specific region. To mitigate this problem, without incurring increasingcosts associated to changing environmental conditions,it is possible to match the adaptive capacity of species to the environment in which they grow. A decisionsupport system was developed to select suitable foragespecies for a given environment. The system is based onthe use of existing information about requirements of the species rather than specific experimentation. Fromthe information gathered, a database was generatedand implemented on ASP.NET in C # and SQL Serverdatabase. This system allows users to search and select pastures and forage species for specific soil and climatic conditions of a particular farm or region, through a user-friendly web platform. La baja oferta de alimento, problema que aqueja a un alto porcentaje de la población ganadera de Colombia, se asocia,en gran medida, a la selección equivocada de especies forrajeras; es decir, con frecuencia las especies sembradas no están adaptadas a la oferta mbiental de una región en particular. Para atenuar el riesgo de la baja oferta forrajera, sin incurrir en costos asociados al cambio de la oferta ambiental, es preciso aprovechar las habilidades fisiológicas de las especies para hacer frente al ambiente donde crecen. Para ello, se desarrolló un sistema de toma de decisiones para la selección de especies forrajeras (STDF), herramienta básica en la transferencia de tecnología agropecuaria que tiene por objetivo atenuar la incertidumbre al definir las especies forrajeras aptas para un ambiente determinado. El sistema se desarrolló a partir de fundamentos básicos de la gestión del conocimiento, por lo que en su construcción no se diseñó ningún experimento, sino que se aprovechó la información existente en el país, proveniente de evaluaciones realizadas en el pasado. A partir de la información recabada, se generó una base de datos de requerimientos de las especies, de tal forma que el sistema, desarrollado e implementado sobre ASP.NET en C# y base de datos SQL Server, relaciona ambientes y requerimientos de cultivos. Dicho sistema permite a los usuarios realizar procesos de búsqueda y selección de especies de pastos y forrajes de acuerdo con las condiciones edafoclimáticas de una determinada finca o región, de manera sencilla y amigable

Proposal of a water-quality index for high andean basins: application to the Chumbao river, Andahuaylas, Peru

Thewater fromthe high Andean rivers is peculiar due to its composition and the geomorphology of its sources, and naturally or anthropogenically contamination is not discarded along its course. This water is used for agriculture and human consumption, therefore knowing its quality is important. This research aimed to proposing and formulate a water-quality index for high Andean basins through the Delphimethod, and its application in the Chumbao River located in Andahuaylas-Peru. Forty-three water-quality parameters were evaluated through the Delphi method, and the water-quality index (WQIHA) was formulated with a weighted average of the weights of the selected parameters, it was compared with the WQI Dinius. For this purpose, ten sampling points were considered along the Chumbao River located between 4274 and 2572 m of altitude and theWQIHA was applied. In addition, field and laboratory analyses were carried out in 2018, 2019, and 2021, in dry and rainy seasons. Twenty parameters were grouped in the physicochemical sub-index (SIPC), heavy metals sub-index (SIHM), and organic matter sub-index (SIOM). Each group contributed with weights of 0.30, 0.30, and 0.40, respectively, for theWQIHA formulation. The SIPC and SIOM showed that the areas near the head of the basin presented excellent and good quality, while the urbanized areas were qualified as marginal to poor; SIHM reported good quality in all points and seasons. Regarding the WQIHA, the index shows good quality in the zones above 3184 m of altitude, contrasting with poor quality downstream, decreasing notably in both seasons, suggesting continuous degradation of the water body

Improvement of the unspecified external causes classification based on the investigation of death in Brazil in 2017

Introdução: Causas inespecíficas de mortalidade estão entre os indicadores tradicionais de qualidade da informação. Objetivo: Verificar o desempenho das 60 cidades do projeto Dados para a Saúde e analisar a reclassificação das causas externas inespecíficas de mortalidade (CEI). Métodos: A partir de registros de 2017 do Sistema de Informações sobre Mortalidade, comparou-se proporções e variações percentuais após investigação das CEI, entre cidades do projeto e demais cidades, e calculou-se percentual de reclassificação para causas específicas. Resultados: As cidades do projeto concentraram 52% (n = 11.759) das CEI do Brasil, das quais 64,5% foram reclassificadas após investigação, enquanto as demais cidades reclassificaram 31%. Resultados foram semelhantes para homens, jovens, negros, cidades metropolitanas, região Sudeste, e em eventos atestados por institutos forenses. Nas cidades do projeto, acidentes de pedestres foram causas com maior reclassificação. Em homens, as CEI migraram para homicídios (23,8%) e acidentes de transporte terrestre (ATT) (11,1%), com destaque para motociclistas (4,4%) e pedestres (4,3%). Em mulheres, essas causas foram alteradas para outras causas acidentais (20,8%), ATT (10,6%) e homicídios (7,9%). CEI migraram para ATT (18,3%) no grupo de idade de 0 a 14 anos, e homicídios (32,5%) no grupo de 15 a 44 anos. Conclusão: As cidades do projeto obtiveram melhores resultados após investigação de CEI, possibilitando analisar a reclassificação para causas específicas, por sexo e faixas etárias.Background: Unspecified causes of death are among the traditional indicators of quality of information. Objective: To verify the performance of the 60 cities in the Data for Health Initiative project and to analyze the reclassification of unspecified external causes of death (UEC). Methods: Using the 2017 records from the Mortality Information System, the proportion and percent change in UEC were compared after investigation between project cities and other cities, and the percent of reclassification to specific external causes was calculated. Results: The project cities comprised 52% (n = 11,759) of the total UEC in Brazil, of which 64.5% were reclassified after investigation, whereas the other cities reclassified 31% of UEC. Results were similar for men, youth, blacks, metropolitan cities, the Southeast region, and deaths attested by forensic institutes. In the project cities, pedestrian traffic accidents were external causes with greater reclassification. In men, the UEC was reclassified to homicides (23.8%) and accident of terrestrial transportation (ATT) (11.1%), with motorcyclists (4.4%) and pedestrians (4.3%) being the most prominent. In women, these causes were changed to other accident causes (20.8%), ATT (10.6%) and homicides (7.9%). UEC changed to ATT (18.3%) in the age groups of 0-14 years old and to homicides (32.5%) in the age groups of 15-44 years. Conclusion: The project cities obtained better results after investigation of UEC, enabling analysis of the reclassification to specific causes by sex and age groups

Role for Maternal Asthma in Severe Human Metapneumovirus Lung Disease Susceptibility in Children

Background: Severity of human metapneumovirus (hMPV) lower respiratory illness (LRTI) is considered similar to that observed for respiratory syncytial virus (RSV). However, differences in severity between these pathogens have been noted, suggesting the degree of illness may vary in different populations. Moreover, a potential association between hMPV and asthma also suggests that hMPV may preferentially affect asthmatic subjects. Methods: In a population-based surveillance study in children aged <2 years admitted for severe LRTI in Argentina, nasopharyngeal aspirates were tested by RT-PCR for hMPV, RSV, influenza A, and human rhinovirus. Results: Of 3947 children, 383 (10%) were infected with hMPV. The hospitalization rate for hMPV LRTI was 2.26 per 1000 children (95% confidence interval [CI], 2.04-2.49). Thirty-nine (10.2%) patients infected with hMPV experienced life-threatening disease (LTD; 0.23 per 1000 children; 95% CI,. 16-.31/1000), and 2 died (mortality rate 0.024 per 1000; 95% CI,. 003-.086). In hMPV-infected children birth to an asthmatic mother was an increased risk for LTD (odds ratio, 4.72; 95% CI, 1.39-16.01). We observed a specific interaction between maternal asthma and hMPV infection affecting risk for LTD. Conclusions: Maternal asthma increases the risk for LTD in children <2 years old hospitalized for severe hMPV LRTI.Fil: Libster, Romina Paula.

Open-Source 3D Printable GPS Tracker to Characterize the Role of Human Population Movement on Malaria Epidemiology in River Networks: A Proof-of-Concept Study in the Peruvian Amazon.

Human movement affects malaria epidemiology at multiple geographical levels; however, few studies measure the role of human movement in the Amazon Region due to the challenging conditions and cost of movement tracking technologies. We developed an open-source low-cost 3D printable GPS-tracker and used this technology in a cohort study to characterize the role of human population movement in malaria epidemiology in a rural riverine village in the Peruvian Amazon. In this pilot study of 20 participants (mean age = 40 years old), 45,980 GPS coordinates were recorded over 1 month. Characteristic movement patterns were observed relative to the infection status and occupation of the participants. Applying two analytical animal movement ecology methods, utilization distributions (UDs) and integrated step selection functions (iSSF), we showed contrasting environmental selection and space use patterns according to infection status. These data suggested an important role of human movement in the epidemiology of malaria in the Peruvian Amazon due to high connectivity between villages of the same riverine network, suggesting limitations of current community-based control strategies. We additionally demonstrate the utility of this low-cost technology with movement ecology analysis to characterize human movement in resource-poor environments

The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library (MaStar) accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) survey which publicly releases infra-red spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the sub-survey Time Domain Spectroscopic Survey (TDSS) data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey (SPIDERS) sub-survey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated Value Added Catalogs (VACs). This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper (MWM), Local Volume Mapper (LVM) and Black Hole Mapper (BHM) surveys

Mapping geographical inequalities in access to drinking water and sanitation facilities in low-income and middle-income countries, 2000-17

Background: Universal access to safe drinking water and sanitation facilities is an essential human right, recognised in the Sustainable Development Goals as crucial for preventing disease and improving human wellbeing. Comprehensive, high-resolution estimates are important to inform progress towards achieving this goal. We aimed to produce high-resolution geospatial estimates of access to drinking water and sanitation facilities. Methods: We used a Bayesian geostatistical model and data from 600 sources across more than 88 low-income and middle-income countries (LMICs) to estimate access to drinking water and sanitation facilities on continuous continent-wide surfaces from 2000 to 2017, and aggregated results to policy-relevant administrative units. We estimated mutually exclusive and collectively exhaustive subcategories of facilities for drinking water (piped water on or off premises, other improved facilities, unimproved, and surface water) and sanitation facilities (septic or sewer sanitation, other improved, unimproved, and open defecation) with use of ordinal regression. We also estimated the number of diarrhoeal deaths in children younger than 5 years attributed to unsafe facilities and estimated deaths that were averted by increased access to safe facilities in 2017, and analysed geographical inequality in access within LMICs. Findings: Across LMICs, access to both piped water and improved water overall increased between 2000 and 2017, with progress varying spatially. For piped water, the safest water facility type, access increased from 40·0% (95% uncertainty interval [UI] 39·4–40·7) to 50·3% (50·0–50·5), but was lowest in sub-Saharan Africa, where access to piped water was mostly concentrated in urban centres. Access to both sewer or septic sanitation and improved sanitation overall also increased across all LMICs during the study period. For sewer or septic sanitation, access was 46·3% (95% UI 46·1–46·5) in 2017, compared with 28·7% (28·5–29·0) in 2000. Although some units improved access to the safest drinking water or sanitation facilities since 2000, a large absolute number of people continued to not have access in several units with high access to such facilities (>80%) in 2017. More than 253 000 people did not have access to sewer or septic sanitation facilities in the city of Harare, Zimbabwe, despite 88·6% (95% UI 87·2–89·7) access overall. Many units were able to transition from the least safe facilities in 2000 to safe facilities by 2017; for units in which populations primarily practised open defecation in 2000, 686 (95% UI 664–711) of the 1830 (1797–1863) units transitioned to the use of improved sanitation. Geographical disparities in access to improved water across units decreased in 76·1% (95% UI 71·6–80·7) of countries from 2000 to 2017, and in 53·9% (50·6–59·6) of countries for access to improved sanitation, but remained evident subnationally in most countries in 2017. Interpretation: Our estimates, combined with geospatial trends in diarrhoeal burden, identify where efforts to increase access to safe drinking water and sanitation facilities are most needed. By highlighting areas with successful approaches or in need of targeted interventions, our estimates can enable precision public health to effectively progress towards universal access to safe water and sanitation
