Prevalencia y factores de riesgo asociados a neurocisticercosis en trabajadores del camal Conchucos, El Agustino, Perú

Introducción: la neurocisticercosis es una de las formas más comunes de enfermedad parasitaria del sistema nervioso central en el Perú. Objetivos: determinar la prevalencia y factores de riesgo asociados a neurocisticercosis en trabajadores de un camal. Material y Métodos: se efectuó un estudio de tipo transversal en 60 trabajadores de un camal de la capital del Perú; a los cuales se les realizó una evaluación clínica, epidemiológica y serológica (EITB), realizándose una tomografía axial computarizada a los EITB positivos. Para establecer el diagnóstico de neurocisticercosis se utilizó los criterios propuestos por Del Bruto y col. en 1996. Para determinar la prevalencia y a su vez la asociación con los factores de riesgo se empleó el paquete estadístico SPSS versión 10.0. Resultados: en la población estudiada la prevalencia de neurocisticercosis fue 1,7% y la seroprevalencia de cisticercosis del 15%. Los inadecuados hábitos higiénicos y la eliminación inadecuada de excretas fueron los factores de riesgo con mayor asociación presentando un OR de 11,6 y 2,14 respectivamente. Conclusiones: la prevalencia de neurocisticercosis para la población estudiada (1,7%) fue menor que la prevalencia nacional encontrada en autopsias de adultos (3,1%). La seroprevalencia encontrada (15%), es bastante similar a las áreas endémicas del Perú y de países como México (10,8%), Ecuador (21,4%) y Colombia (19,6%). El desconocimiento y la falta de información de estas personas sobre los mecanismos de transmisión de la neurocisticercosis explicarían la asociación con los factores de riesgo mencionados

Khuri-Treiman analysis of J/ψ→π+π−π0J/\psi\to\pi^{+}\pi^{-}\pi^{0}

We study the decay $J/\psi\to\pi^{+}\pi^{-}\pi^{0}$ within the framework of the Khuri-Treiman equations. We find that the BESIII experimental di-pion mass distribution in the $\rho(770)$-region is well reproduced with a once-subtracted $P$-wave amplitude. Furthermore, we show that $F$-wave contributions to the amplitude improve the description of the data in the $\pi\pi$ mass region around 1.5 GeV. We also present predictions for the $J/\psi\to\pi^{0}\gamma^{*}$ transition form factor.Comment: 20 pages, 9 figure

Identification of candidate pelagic marine protected areas through a seabird seasonal-, multispecific- and extinction risk-based approach

With increasing pressure on the oceans from environmental change, there has been a global call for improved protection of marine ecosystems through the implementation of marine protected areas (MPAs). Here, we used species distribution modelling (SDM) of tracking data from 14 seabird species to identify key marine areas in the southwest Atlantic Ocean, valuing areas based on seabird species occurrence, seasonality and extinction risk. We also compared overlaps between the outputs generated by the SDM and layers representing important human threats (fishing intensity, ship density, plastic and oil pollution, ocean acidification), and calculated loss in conservation value using fishing and ship density as cost layers. The key marine areas were located on the southern Patagonian Shelf, overlapping extensively with areas of high fishing activity, and did not change seasonally, while seasonal areas were located off south and southeast Brazil and overlapped with areas of high plastic pollution and ocean acidification. Non-seasonal key areas were located off northeast Brazil on an area of high biodiversity, and with relatively low human impacts. We found support for the use of seasonal areas depending on the seabird assemblage used, because there was a loss in conservation value for the seasonal compared to the non-seasonal approach when using ‘cost’ layers. Our approach, accounting for seasonal changes in seabird assemblages and their risk of extinction, identified additional candidate areas for incorporation in the network of pelagic MPAs

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Family Businesses and Adaptation: A Dynamic Capabilities Approach

The main objective of this research was to propose a framework centred on the dynamic capabilities approach, and to be applied in the context of family businesses’ adaption to their changing business environment. Data were gathered through interviews with ten FBs operating in Western Australia. Based on the findings, the clusters of activities, sensing, seizing, and transforming emerged as key factors for firms’ adaptation, and were reinforced by firms’ open culture, signature processes, idiosyncratic knowledge, and valuable, rare, inimitable and non-substitutable attributes. Thus, the usefulness of the proposed framework was confirmed. Implications and future research opportunities are presented. © 2018, The Author(s)
