Effects of forage supplements on milk production and chemical properties, in vivo digestibility, rumen fermentation and N excretion in dairy cows offered red clover silage and corn silage or dry ground corn

peer-reviewedThis study concerned the effects of partial substitution of clover silage with high starch forages on milk production and chemical composition, in vivo digestibility, rumen fermentation pattern and nitrogen excretion of dairy cows. Sixteen dairy cows were separated into two groups and were assigned to treatments in a two-period crossover design. Two forage supplements were used: corn silage (CS) and dry ground corn (DG). All animals received 4.5 kg of concentrate dry matter per day. Results showed no significant difference between the forage supplements for milk production, while significant differences (P<0.01) were observed for milk fat, milk protein and nitrogen utilisation efficiency (42 v. 4.0 g/kg, 3.5 v. 3.3 g/kg and 222 v. 188 g/kg, respectively, for DG and CS). Faecal N excretion did not differ between forage supplements, but urinary N excretion was higher for CS (P<0.05). No significant differences were observed between treatments for rumen fluid pH or for rumen fluid concentrations of ammonium nitrogen or of acetic, propionic or butyric acids. Dry matter intake and the in vivo digestibility of dry matter, organic matter, acid detergent fibre and neutral detergent fibre were all higher for CS compared with DG.The authors are grateful to the Environmental Office of the Cantabrian Government for funding the project 05-640.02-2174

Vagus Nerve Stimulation in Medically- Resistant Epilepsy: Efficacy and Tolerance

Background: Epilepsy is a common neurological disease that affects 1% of the population. One third of patients with epilepsy will not respond to antiseizure medications. The most effective treatment when a patient has medically resistant epilepsy is epilepsy surgery. Unfortunately, in many cases surgery is not possible. Neuromodulation is a therapy used in those patients and Vagus Nerve Stimulation (VNS) is the most common type. There are many studies focusing on seizure reduction using VNS, it is still unclear which patients will obtain the greatest benefits. Objective: To define the seizure response post-VNS implantation, to determine predictive factors associated with good outcomes after VNS implantation and to evaluate complications and side effects. Analysis will be completed in the total sample of VNS cases, in the paediatric subgroup, in medically resistant generalized epilepsy and pregnant women implanted with VNS. Patients & Methods: Patients with medically resistant epilepsy implanted with VNS at the London Health Science Centre-Western University, from 1997 to July 2018. Results: 1) VNS in epilepsy: 114 patients were included. Median seizure rate reduction was - 67.8% and 55.6% (n=41) had a ≥50% seizure reduction. There was a reduction of hospitalization after VNS implantation from 89.5% (n=102) to 45.6% (n=52). 5.3% (n=6) developed side effects associated with the implantation; and side effects were reported in 63.2% (n=72). 2) Paediatric Group: 22 patients were included. The median age when the VNS was implanted was 13. A ≥50% seizure reduction was achieved in 50% (n=11) and the median seizure reduction was -75%. Side effects were detected in 54.5% (n=12). 3) 46 patients were included in this study with a history of medically resistant generalized epilepsy. The mean age at implantation was 24 years-old. Of the LGS group 41.7% (n=12) of patients had an overall seizure reduction of ≥50%, and in the GGE group 64.7% (n=11) had a seizure reduction of ≥50%. There was a significant reduction of seizure-related hospital admissions. 4) Four patients and seven pregnancies were included. The median duration since implantation was 3.17 years. Three required c-sections, one related to failure to progress, the second due to pre-eclampsia and the third due to breach presentation. All babies were healthy, except one with developmental delay of unclear severity. Conclusion: 1) VNS can reduce the number of seizures by 50% in more than half of the patients implanted. VNS has shown a reduction in hospitalization. It is a safe therapy with frequent mild side effects. 2) The paediatric population obtained similar results compared to the total sample. 3) VNS should be considered as a treatment in patients with therapy resistant generalized epilepsy, especially in cases with GGE. 4) Our small sample suggests VNS is a relatively safe therapy during pregnancy, however, larger sample series should be collected

Evaluación docente y aprendizaje por competencia de los estudiantes

Métodos Estadísticos para la Investigación es una asignatura que genera un grado de dificultad en la enseñanza del docente y el aprendizaje del alumno. En el aula se investigó si existe una relación entre la evaluación docente y el aprendizaje por competencias de los estudiantes. El objetivo era determinar la relación entre la evaluación docente y el aprendizaje por competencias de los estudiantes, para luego formular la hipótesis: la evaluación docente se relaciona con el aprendizaje por competencias de los estudiantes. La investigación fue descriptiva, prospectiva, transversal y analítica. De igual manera fue aplicada, relacional y no experimental. Se validó el instrumento para identificar, definir y medir el constructo. Se aplicó el alfa de Cronbach para determinar la consistencia interna del instrumento, la correlación de Pearson para medir la asociación entre las variables, y el P-valor para contrastar la hipótesis. La conclusión fue que la evaluación docente se relaciona positivamente con el aprendizaje por competencias de los estudiantes. En consecuencia, el docente debe aprovechar la evaluación como una oportunidad para mejorar la labor didáctica en el aula, y contribuir en el proceso de formación integral del futuro profesional del Derecho

La arquitectura sensorial de Frida Escobedo

[ES] Existe una toma de conciencia actual por parte de algunos arquitectos contemporáneos en retomar los principios y valores de la arquitectura sensorial y emocional, olvidados en las últimas décadas. El presente trabajo sitúa el foco en la obra fenomenológica de la arquitecta mexicana Frida Escobedo. Tras el racionalismo y funcionalismo característicos del Movimiento Moderno (primera década del siglo XX), la inquietud por la arquitectura sensorial se hizo patente con Luís Barragán; interés que Escobedo retoma en la actualidad. A partir de un análisis previo de los sistemas y modos de percepción, así como de los diferentes fenómenos que hacen de la arquitectura una experiencia sensorial completa, se identifican y examinan aquellos que se enfatizan en las obras de Escobedo y se extraen conclusiones útiles para poder afrontar el diseño y construcción de la arquitectura venidera.[EN] Some contemporary architects are becoming aware of the importance of the principles and values of the sensorial and emotional architecture, forgotten in the last decades. The present assignment focuses on the phenomenological work of the Mexican architect Frida Escobedo. After the rationalism and functionalism characteristic of the Modern Movement (first decade of the 20th century), the interest in sensory architecture became evident with Luís Barragán; interest that Escobedo retakes today. From a previous analysis of the systems and modes of perception and of the different phenomena that make architecture a complete sensory experience, those that stand out in Escobedo¿s work are examined. Finally, useful conclusions are drawn in order to be able to face the design and construction of the coming architecture.Suller Cornejo, C. (2018).
