Modelado de la sismicidad en Colombia a partir de características de la litosfera terrestre

En el presente artículo se realizó la estimación de modelos del proceso de Poisson no homogéneo, aso- ciado al patrón de sismos en Colombia utilizando covariables descriptivas de la litosfera terrestre tales como la altitud del terreno, anomalías magnéticas e isostáticas, y mediciones de distancia a estructu- ras geológicas tales como fallas, bordes de placa y volcanes. En este estudio se confirmó que los sismos tienden a ocurrir en las cercanías a determinadas es- tructuras geológicas, en zonas con importantes ano- malías gravimétricas, tanto positivas como negativas, y en zonas con valores específicos de anomalías magnéticas y de altitud.

Efectos de los fungicidas organofosforados y carbamatos en la salud de los escolares / Effects of organophosphate and carbamate fungicides in school health

El objetivo de la presente investigación fue determinar mediante pruebas de Colinesterasa, los efectos de los fungicidas organofosforados y carbamatos utilizados en las fincas bananeras, en la salud de los estudiantes de las escuelas: Manuel Centeno Garzón y Manuela Cañizares, ubicadas en la zona urbano marginal de Machala, Ecuador, en el año 2014. Se realizó un estudio descriptivo de corte transversal, epidemiológico, analítico-observacional, tipo “casos y controles”. Mediante pruebas de correlación entre los valores de enzima colinesterasa, se diferenció la presencia o no de lesiones dermatológicas, tales como resequedad, mácula y otras. Concluyendo que el 100 % presentó por lo menos uno de los síntomas en relación a la exposición de fungicidas y que existe una implicación de colinesterasa alterada con una ligera predisposición a desarrollar enfermedades de la piel, (Odds ratio: 1.29), además el 60 % presentó estado de desnutrición. AbstractThe objective of this research was to determine through testing cholinesterase effects of organophosphate and carbamate fungicides used on banana plantations in the health of school students: Manuel Centeno Garzón and Manuela Canizares, located in the marginal urban area Machala, Ecuador, in 2014.

Classifying organisms and artefacts by their outline shapes

We often wish to classify objects by their shapes. Indeed, the study of shapes is an important part of many scientific fields, such as evolutionary biology, structural biology, image processing and archaeology. However, mathematical shape spaces are rather complicated and nonlinear. The most widely used methods of shape analysis, geometric morphometrics, treat the shapes as sets of points. Diffeomorphic methods consider the underlying curve rather than points, but have rarely been applied to real-world problems. Using a machine classifier, we tested the ability of several of these methods to describe and classify the shapes of a variety of organic and man-made objects. We find that one method, based on square-root velocity functions (SRVFs), outperforms all others, including a standard geometric morphometric method (eigenshapes), and that it is also superior to human experts using shape alone. When the SRVF approach is constrained to take account of homologous landmarks it can accurately classify objects of very different shapes. The SRVF method identifies a shortest path between shapes, and we show that this can be used to estimate the shapes of intermediate steps in evolutionary series. Diffeomorphic shape analysis methods, we conclude, now provide practical and effective solutions to many shape description and classification problems in the natural and human sciences.</p

SARS-CoV-2 Neutralizing Antibodies in Mexican Population: A Five Vaccine Comparison

Neutralizing antibodies (NAs) are key immunological markers and are part of the humoral response of the adaptive immune system. NA assays determine the presence of functional antibodies to prevent SARS-CoV-2 infection. We performed a real-world evidence study to detect NAs that confer protection against SARS-CoV-2 after the application of five vaccines (Pfizer/BioNTech, AstraZeneca, Sinovac, Moderna, and CanSino) in the Mexican population. Side effects of COVID-19 vaccines and clinical and demographic factors associated with low immunogenicity were also evaluated. A total of 242 SARS-CoV-2-vaccinated subjects were recruited. Pfizer/BioNTech and Moderna proved the highest percentage of inhibition in a mono-vaccine scheme. Muscular pain, headache, and fatigue were the most common adverse events. None of the patients reported severe adverse events. We found an estimated contagion-free time of 207 (IQR: 182–231) and 187 (IQR: 184–189) days for Pfizer/BioNTech and CanSino in 12 cases in each group. On the basis of our results, we consider that the emerging vaccination strategy in Mexico is effective and safe

Recommendations for SARS-CoV- 2/ COVID-19 testing: a scoping review of current guidance

Background Testing used in screening, diagnosis and follow-up of COVID-19 has been a subject of debate. Several organisations have developed formal advice about testing for COVID-19 to assist in the control of the disease. We collated, delineated and appraised current worldwide recommendations about the role and applications of tests to control SARS-CoV- 2/COVID-19. Methods We searched for documents providing recommendations for COVID-19 testing in PubMed, EMBASE, LILACS, the Coronavirus Open Access Project living evidence database and relevant websites such as TRIP database, ECRI Guidelines Trust, the GIN database, from inception to 21 September 2020. Two reviewers applied the eligibility criteria to potentially relevant citations without language or geographical restrictions. We extracted data in duplicate, including assessment of methodological quality using the Appraisal of Guidelines for Research and Evaluation-II tool. Results We included 47 relevant documents and 327 recommendations about testing. Regarding the quality of the documents, we found that the domains with the lowest scores were ‘Editorial independence’ (Median=4%) and ‘Applicability’ (Median=6%). Only six documents obtained at least 50% score for the ‘Rigour of development’ domain. An important number of recommendations focused on the diagnosis of suspected cases (48%) and deisolation measures (11%). The most frequently recommended test was the reverse transcription-PCR (RT-PCR) assay (87 recommendations) and the chest CT (38 recommendations). There were 22 areas of agreement among guidance developers, including the use of RT-PCR for SARS-Cov- 2 confirmation, the limited role of bronchoscopy, the use chest CT and chest X-rays for grading severity and the co-assessment for other respiratory pathogens. Conclusion This first scoping review of recommendations for COVID-19 testing showed many limitations in the methodological quality of included guidance documents that could affect the confidence of clinicians in their implementation. Future guidance documents should incorporate a minimum set of key methodological characteristics to enhance their applicability for decision making.Instituto de Salud Carlos III 2017/CD17/00219European Social Fund 2014-2020, 'Investing in your future'Spanish Governmen
