Forrajes hidropónicos: una alternativa para la alimentación de animales domésticos

Currently, in critical times of confinement, hydroponics is a viable alternative that allows the production of plant biomass derived from the initial development of plants in the stages of germination and early growth of seedlings from feasible seeds, it is the sowing of soilless cultivation, this method facilitates the productive, sustainable, and ecological development of plants. Hydroponic crops are developed in a medium or culture system fed by a nutrient solution that offers the precise food for the entire period of growth of the forages, free of pesticides andfungicides with this we get healthy food for the feeding of domestic animals. In addition, it allows the use of simple or complex structures to produce fodder, taking advantage of spaces or areas such as terraces, infertile soils, rugged terrain, technical or traditional greenhouses. Based on this idea, techniques were deployedthat are supported by using substrates, or methods with contributions of nutrient solutions, always considering the needs of the plant such as temperature, humidity, water, and nutrients. Based on prac-tice, the benefits per unit of planted area are high due to greater consistency, productivity, safety, and effi-ciency in the use of water, light, and nutrients, and it is also economically viable that deserves to be considered by small and medium- sized companies. rural producers of domestic animals.En la actualidad en tiempos críticos de confinamiento la hidroponía es una alternativa viable que permite la pro-ducción de biomasa vegetal derivada a partir del desarrollo inicial de las plantas en las etapas de germinación y crecimiento anticipado de plántulas a partir de semillas factibles, es la siembra de cultivo sin suelo, este método facilita el desarrollo productivo, sostenible y ecológico de las plantas. Los cultivos hidropónicos se desarrollan en un medio o sistema de cultivo alimentados por solución nutritiva que ofrece el alimento preciso para todo el pe-ríodo de crecimiento de los forrajes, libre de pesticidas y fungicidas con esto conseguimos alimentos saludables para la alimentación de animales domésticos. Además, permite utilizar estructuras simples o complejas para la producción de forrajes aprovechando espacios o áreas como terrazas, suelos infértiles, terrenos escabrosos, inver-naderos tecnificados o tradicionales. A partir de esta idea se desplegaron técnicas que se apuntalan a utilizar sus-tratos, o métodos con aportes de soluciones de nutrientes, tomando en cuenta siempre las necesidades de la planta como la temperatura, humedad, agua y nutrientes. Fundados en la práctica, los beneficios por unidad de área sem-brada son altos debido a una mayor consistencia, productividad, inocuidad y eficacia en el uso de los recursos agua, luz y nutrientes, además es económicamente viable que merece ser considerada por los pequeños y medianos productores rurales de animales domésticos

Validation of the ICH score in patients with spontaneous intracerebral haemorrhage admitted to the intensive care unit in Southern Spain

Objective Validation of the intracerebral haemorrhage (ICH) score in patients with a diagnosis of spontaneous ICH admitted to the intensive care unit (ICU). Results A total of 336 patients were included. 105 of whom underwent surgery. Median (IQR) age: 62 (50–70) years. APACHE-II: 21(15–26) points, GCS: 7 (4–11) points, ICH score: 2 (2–3) points. 11.1% presented with bilateral mydriasis on admission (mortality rate=100%). Intraventricular haemorrhage was observed in 58.9% of patients. In-hospital mortality was 54.17% while the APACHE-II predicted mortality was 57.22% with a standardised mortality ratio (SMR) of 0.95 (95% CI 0.81 to 1.09) and a Hosmer-Lemenshow test value (H) of 3.62 (no significant statistical difference, n.s.). 30-day mortality was 52.38% compared with the ICH score predicted mortality of 48.79%, SMR: 1.07 (95% CI 0.91 to 1.23), n.s. Mortality was higher than predicted at the lowest scores and lower than predicted in the more severe patients, (H=55.89, p<0.001), Gruppo Italiano per la Valutazione degli Interventi in Terapia Intensiva calibration belt (p<0.001). The area under a receiver operating characteristic (ROC) curve was 0.74 (95% CI 0.69 to 0.79). Conclusions ICH score shows an acceptable discrimination as a tool to predict mortality rates in patients with spontaneous ICH admitted to the ICU, but its calibration is suboptimal

Determinación de la edad propicia para la gonadectomía en pollos criollos

The objective of the research was to improve the productive parameters in Creole chickens through gonadectomy in the Tungurahua Province, Ecuador. A completely randomized design with three treatments and a control was used, the results were subjected to an analysis of variance (ADEVA) for the separation of means and the Tukey test of 5%, the factors under study were: T1 (8), T2 (9) and T3 (10), castrated weeks of age, and uncastrated chickens (20 birds / treatment), with a productive period after castration of 12 weeks. Weight gain 12 weeks after castration was higher in chickens operated on at 8 weeks of age, (343.6 g bird / week, p &lt;0.05). The lowest feed consumption was in week 3 post castration (p &lt;0.05). Roosters castrated at 8 and 9 weeks had better feed con-version (6.33 and 6.53, respectively) (p &lt;0.05). Carcass yield was higher in castrated roosters compared to the uncastrated control group (p &lt;0.01). The mortality. It was better in T1 (8 weeks old) with 0%. For this reason, the application of the surgical technique performed at of age is the most recommended.El objetivo de la investigación fue determinar la edad propicia para mejorar los parámetros productivos en pollos criollos mediante la gonadectomía en la Provincia de Tungurahua, Ecuador. Se utilizó un diseño completamente al azar con tres tratamientos y un testigo, los resultados se sometieron a un análisis de varianza (ADEVA) para la separación de medias y la prueba de Tukey 5%, los factores en estudio fueron: T1 (8), T2 (9) y T3 (10), semanas de edad castrados, y pollos sin castrar (testigo), (20 aves/tratamiento), con un periodo productivo posterior a la castración de 12 semanas. La ganancia de peso a las 12 semanas de la castración fue mayor en pollos interveni-dos a las 8 semanas de edad, (343.6 g ave/semana, p&lt;0.05). El menor consumo de alimento fue en la semana 3 post castración (p&lt;0.05). Los gallos castrados a las 8 y 9 semanas registraron mejor conversión alimenticia (6.33 y 6.53, respectivamente) (p&lt;0.05).

Clinical aspects of foot health and their influence on quality of life among breast cancer survivors: a case–control study

P. 545–551The aim of this study was to analyze and compare foot health and general health in a sample of women divided into two groups: 1) those with breast cancer and undergoing chemotherapy treatment and 2) healthy women without breast cancer and with normalized reference values. Methods: A case–control observational study was performed. Two-hundred women with a mean age of 51.00±8.75 years were recruited from podiatric medicine and surgery clinics from the University of Extremadura (Plasencia, Spain) and the Hospital Infanta Cristina (Badajoz, Spain). The women were divided into case and control groups (undergoing chemotherapy treatment and healthy women, respectively). The Foot Health Status Questionnaire was used to assess foot health domain scores. Results: Significant differences between both groups were seen for foot pain (P=0.003), foot function (P<0.001), physical activity (P<0.001), social capacity (P<0.001), and vigor (P=0.001). The remaining domains (footwear, general health, and foot health) did not show significant differences between the two groups (P≥0.01). Conclusion: Women with breast cancer presented a lower foot health-related quality of life. Clinical aspects with emphasis on foot pain and disability were increased. Furthermore, physical activity, social capacity, and vigor were affected. Therefore, general health care and foot problem prevention for breast cancer survivors should be given more consideration.S

Characterization of gross domestic expenditure on R&D in Latin American countries during 2008-2017

ABSTRACT Gross domestic expenditure on R&D is one of the most analyzed indicators in terms of growth and economic development of a country. Improving this indicator would lead to the achievement of the SDG that UN Member States adopted in 2015, which responds to build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation. In this research, a descriptive analysis of the GDE on R&D indicator of Latin American countries, in the period 2008 - 2017, has been carried out in order to analyze and compare it. Firstly, information is presented on the GDE on R&D indicator. Then, the analysis and comparison of the indicator among Latin American countries is shown. In the same way, for the countries that obtain better results, they are compared with the values of the indicator of other countries of Ibero-America and North America. Brazil is the only Latin American country that presents the highest average value of the indicator (0.012), above the average value of Latin American and Caribbean countries, and even of Ibero-American countries
