Abstract

The objective was to evaluate a method to reduce the calcium nitrate release rate in a simulated rumen fermentation environment, and to determine its effect on dry matter degradation and methane production. In the in vitro experiment, kikuyu grass (Cenchrus clandestinus, Hochst ex Chiov) (KK) was used as the base feed and the addition of protected nitrate (PN), free nitrate (FN) and urea (KU) to the fermentation environment. The amount of nitrate added corresponded to 3 % of the incubated dry matter. The data were analyzed with repeated measures over time considering treatment and time as fixed effects and the rumen inoculum donor animal as a random factor. After 24 h of incubation, FN and PN reduced dry matter degradation by 11.4 and 15 %, respectively. The addition of nitrate significantly reduced methane production. The difference in methane production rates expressed in ml/g of degraded dry matter between the FN (21.0) and PN (31.2) treatments at 48 h of incubation indicates a lower nitrate release rate as a consequence of the protection method employed. The results of this trial show that the inclusion of protected nitrates at levels corresponding to 3 % of the incubated dry matter can reduce methane production by 53 %. [ABSTRACT FROM AUTHOR]

Abstract

AbstractBackgroundMethodsResultsConclusionCombination therapy is an attractive therapeutic option for extensively drug-resistant (XDR) Pseudomonas aeruginosa infections. Existing data support the combination of aztreonam and ceftazidime/avibactam (CZA) against class serine-β-lactamase (SBL)- and metallo-β-lactamase (MBL) - producing Enterobacterales. However, data about that combination against SBL- and MBL-producing P. aeruginosa are scarce. The objective of the study was to assess the in vitro activity of CZA and aztreonam alone and in combination against SBL- and MBL-producing XDR P. aeruginosa isolatesThe combination was analyzed by means of the hollow-fiber infection model in three selected carbapenemase-producing P. aeruginosa isolates that were representative of the three most common XDRP. aeruginosa high-risk clones (ST175, ST111, ST235) responsible for global nosocomial infection outbreaks.The three isolates were nonsusceptible to CZA and nonsusceptible to aztreonam. In the dynamic hollow-fiber infection model, the combination of CZA plus aztreonam exerts a bactericidal effect on the isolates, regardless of their resistance mechanism and demonstrates synergistic interactions against three isolates, achieving a bacterial reduction of 5.07 log10 CFU/ml, 5.2 log10 CFU/ml and 4 log10 CFU/ml, respectively.The combination of CZA and aztreonam significantly enhanced the in vitro efficacy against XDR P. aeruginosa isolates compared to each monotherapy. This improvement suggests that the combination could serve as a feasible treatment alternative for infections caused by carbapenemase-producing XDR P. aeruginosa, especially in scenarios where no other treatment options are available.

Abstract

The use of collars, pedometers or activity tags is expensive to record cattle's behavior in short periods (e.g. 24h). Under this particular situation, the development of low-cost and easy-to-use technologies is relevant. Similar to smartphone apps for human activity recognition, which analyzes data from embedded triaxial accelerometer sensors, we develop an Android app to record activity in cattle. Four main steps were followed: a) data acquisition for model training, b) model training, c) app deploy, and d) app utilization. For data acquisition, we developed a system in which three components were used: two smartphones and a Google Firebase account for data storage. For model training, the generated database was used to train a recurrent neural network. The performance of training was assessed by the confusion matrix. For all actual activities, the trained model provided a high prediction (> 96 %). The trained model was used to deploy an Android app by using the TensorFlow API. Finally, three cell phones (LG gm730) were used to test the app and record the activity of six Holstein cows (3 lactating and 3 non-lactating). Direct and non-systematic observations of the animals were made to contrast the activities recorded by the device. Our results show consistency between the direct observations and the activity recorded by our Android app., El uso de podómetros o collares para registrar el comportamiento del ganado en períodos cortos de tiempo (e.g. 24 h) es costoso. En esta situación particular, el desarrollo de tecnologías de bajo costo y fáciles de usar es relevante. Al igual que las aplicaciones de teléfonos inteligentes para el reconocimiento de la actividad humana, las cuales analizan datos de sensores de aceleración integrados, en este trabajo desarrollamos una aplicación de Android para registrar la actividad del ganado. Para el desarrollo de esta aplicación, se siguieron cuatro pasos principales: a) adquisición de datos para el entrenamiento del modelo, b) entrenamiento del modelo, c) desarrollo de la aplicación y d) utilización de la aplicación. Para la adquisición de datos, desarrollamos un sistema en el que se utilizaron tres componentes: dos teléfonos inteligentes (uno en la vaca y otro para el observador) y una cuenta de Google Firebase para el almacenamiento de datos. Para el entrenamiento del modelo, la base de datos generada se utilizó para entrenar una red neuronal recurrente. El rendimiento del entrenamiento se evaluó mediante la matriz de confusión. Para todas las actividades, el modelo entrenado proporcionó una predicción alta (> 96 %). El modelo entrenado se utilizó para desarrollar una aplicación de Android con la API de TensorFlow. Finalmente, se utilizaron tres teléfonos celulares (LG gm730) para registrar la actividad de seis vacas Holstein (3 en producción y 3 secas). Se realizaron observaciones directas y no sistemáticas de los animales para contrastar las actividades registradas por el dispositivo. Los resultados mostraron coherencia entre las observaciones directas y la actividad registrada por el dispositivo.

Abstract

We present a woman in her 40s who arrived at the emergency room with hypertension and optic ataxia. Her medical history is only relevant for obesity. Her lumbar puncture revealed high intracranial pressure and lymphocytic pleocytosis, and her neuroimaging tests, including angiography and venography, were normal. The patient improved after a cerebrospinal fluid drainage with a lumbar puncture, and her clinical manifestations resolved in parallel to the lymphocytic pleocytosis. The patient was diagnosed with a syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis and fully recovered 21 days after her discharge.

Abstract

Introducción: La cooperación es un elemento relevante para el éxito terapéutico en procesos de ortodoncia. En el caso particular de los adolescentes, conocer su grado de cooperación permite al ortodoncista considerar, en la planeación de la intervención, comportamientos y actitudes que contribuyan a los propósitos del tratamiento. Objetivo: Analizar las evidencias de validez de la medida de cooperación del paciente ortodóncico, propuesta por Slakter, Albino, Fox y Lewis, siguiendo los lineamientos de Wolfe y Smith. Métodos: Estudio de validación anidado en un diseño de cohortes en el cual se siguieron, entre enero del 2014 y noviembre del 2015, 132 adolescentes pacientes activos de tratamiento de ortodoncia correctiva residentes de la ciudad de Medellín. Se estimaron las locaciones y estadísticos de ajuste de los ítems, confiabilidad, unidimensionalidad y funcionamiento diferencial por características clínicas y demográficas de los participantes. Se presenta el mapa de Wright. Resultados: Cuatro ítems fueron eliminados de la escala. A partir de los seis restantes se obtuvo una medida con una confiabilidad de .74 y capacidad para explicar el 74.9% de la varianza. Se identificó funcionamiento diferencial de los ítems según tipo de maloclusión y según antecedente de ortodoncia interceptiva. Conclusión: La validez de la medida se ve afectada por limitaciones en la generalización del constructo según características clínicas relevantes de los adolescentes.

Abstract

El presente trabajo investigativo trata de las Características incidentes en las Infecciones de Transmisión Sexual en mujeres adolescentes que asisten al Puesto de Salud La Empresa, en el municipio de la Dalia, durante el III trimestre del año 2017. Dentro de los objetivos se encuentran: caracterizar Socio-demográficamente alas adolescentes en estudio, describir factores de riesgos incidentes en las ITS en adolescentes seleccionadas, identificar el agente causal patológico más prevalente de las ITS en pacientes estudiadas y clasificar el nivel de incidencia según la Infección de Transmisión Sexual. El estudio es de tipo descriptivo porque en ella se detalla lo que ocurre con los individuos en estudio, con un enfoque cuali-cuantitativo porque se analizan datos numéricos y cualidades de las variables en estudio. Área de estudio: puesto de salud La Empresa, municipio de la Dalia. El universo equivale a 100 pacientes activas adolescentes, de la cual tomamos una muestra de 14 pacientes adolescentes que han tenido alguna infección vaginal por medio del método no probabilístico a conveniencia ya que se tomó en cuenta solo las pacientes adolescentes que están dentro del programa de planificación familiar, que se han realizado su PAP y que tienen alguna ITS a quienes se le aplicó una encuesta. Después de realizar el estudio se concluye en: La incidencia de las ITS es alta, por el déficit de conocimientos de las adolescentes acerca de dichas infecciones, además del poco uso de preservativos. Las edades que más inciden en las ITS se encuentran en adolescentes de 15 a 19 años. Dentro de los factores de riesgos que conllevaron alas adolescentes a adquirir una ITS están: tener más de un compañero sexual, consumir tabaco, practicar sexo anal, vaginal y oral sin protección. El agente causal que más incide en las adolescentes en estudio son: virus, bacterias y parásitos. El nivel de incidencia más alto está dado por los virus, que conllevan alas ITS
