Asociación entre componentes de rendimientos en fibra de algodonero (gossypium hirsutum L.)

En la finca el dorado vereda de Bellavista, departamento del Magdalena, se llevó a cabo el ensayo denominado “asociación entre componentes de rendimiento en fibra del algodonero” (gossypium hirsutum L.), con el objeto de determinar la posible relación existente entre los factores en dicho estudio. Estos factores son: peso de cápsula, índice de fibra y porcentaje de fibra. El diseño experimental seguido fue el de correlación parcial, utilizando el promedio arbitrario y las tablas de doble entrada, elaboradas las tablas de correlaciones entre el peso de las cápsulas e índice de fibra, se notó significación, lo cual nos indica que hay asociación entre estos factores, igual ocurrió entre el porcentaje de fibra y el peso de la cápsula, pero entre el porcentaje de fibra y el índice de fibra se notó correlación negativa debido a que un carácter varia en dirección opuesto al otro

Lung Paragonimiais in Children: Report of Two Cases

RESUMEN: La paragonimiasis es una zoonosis parasitaria, de transmisión alimentaria, causada por especies de tremátodos del género Paragonimus, presente en áreas tropicales y subtropicales de Asia, África y América. El ser humano se infecta mediante la ingestión de crustáceos de agua dulce crudos o mal cocidos. La infección afecta principalmente los pulmones, con desarrollo de múltiples manifestaciones clínicas y radiológicas, dependiendo del momento del ciclo vital del parásito. El diagnóstico diferencial más importante de esta enfermedad es la tuberculosis pulmonar. En este artículo se describe esta enfermedad en dos niñas con diferentes manifestaciones pulmonares. La paragonimiasis se debe sospechar en pacientes con tos crónica, esputo herrumbroso, dolor torácico, con o sin compromiso cerebral, que viven o han residido en una zona endémica y que presentan una eosinofília elevada, con cambios radiológicos sugestivos del síndrome de Loeffler.ABSTRACT: Paragonimiasis is a parasitic, food-borne zoonosis, caused by species of trematodes of the genus Paragonimus, found in tropical and subtropical areas of Asia, Africa and America. Human beings become infected by ingestion of raw or undercooked freshwater shellfish. The infection primarily affects the lungs, with the development of multiple clinical and radiological manifestations, depending on the moment in the life cycle of the parasite. The most important differential diagnosis of this disease is pulmonary tuberculosis. We report two cases of lung paragonimiasis in aboriginal Colombian girls with different pulmonary manifestations. Paragonimiasis should be suspected in patients with chronic cough, rusty sputum, chest pain, with or without brain involvement, who live or have lived in en-demic areas and have a highlevel eosinophilia with radiographic changes suggestive of Loeffler’s syndrome

Clustering COVID-19 ARDS patients through the first days of ICU admission. An analysis of the CIBERESUCICOVID Cohort

Background Acute respiratory distress syndrome (ARDS) can be classified into sub-phenotypes according to different inflammatory/clinical status. Prognostic enrichment was achieved by grouping patients into hypoinflammatory or hyperinflammatory sub-phenotypes, even though the time of analysis may change the classification according to treatment response or disease evolution. We aimed to evaluate when patients can be clustered in more than 1 group, and how they may change the clustering of patients using data of baseline or day 3, and the prognosis of patients according to their evolution by changing or not the cluster.Methods Multicenter, observational prospective, and retrospective study of patients admitted due to ARDS related to COVID-19 infection in Spain. Patients were grouped according to a clustering mixed-type data algorithm (k-prototypes) using continuous and categorical readily available variables at baseline and day 3.Results Of 6205 patients, 3743 (60%) were included in the study. According to silhouette analysis, patients were grouped in two clusters. At baseline, 1402 (37%) patients were included in cluster 1 and 2341(63%) in cluster 2. On day 3, 1557(42%) patients were included in cluster 1 and 2086 (57%) in cluster 2. The patients included in cluster 2 were older and more frequently hypertensive and had a higher prevalence of shock, organ dysfunction, inflammatory biomarkers, and worst respiratory indexes at both time points. The 90-day mortality was higher in cluster 2 at both clustering processes (43.8% [n = 1025] versus 27.3% [n = 383] at baseline, and 49% [n = 1023] versus 20.6% [n = 321] on day 3). Four hundred and fifty-eight (33%) patients clustered in the first group were clustered in the second group on day 3. In contrast, 638 (27%) patients clustered in the second group were clustered in the first group on day 3.Conclusions During the first days, patients can be clustered into two groups and the process of clustering patients may change as they continue to evolve. This means that despite a vast majority of patients remaining in the same cluster, a minority reaching 33% of patients analyzed may be re-categorized into different clusters based on their progress. Such changes can significantly impact their prognosis

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

La ganadería ante escenarios complejos.

La calidad de las contribuciones, producto de la pluma de especialistas en los temas tratados, el presente es un libro que esperamos, basándonos en la importancia de los temas tratados, sea de utilidad y abone a la reflexión de los estudiosos de la ganadería mexicana y, por supuesto, en beneficio de las familias ganaderas y de los consumidores de sus productos.este libro refleja en muchos sentidos la situación de la ganadería mexicana, a la que se le están demandando mayor producción y productividad, que los procesos productivos tengan la menor huella ecológicposible, que los alimentos sean inocuos, que se abatan costos de producción y, cada vez aumentan las presiones de diversos grupos para, que se incluyan los protocolos de bienestar animal, solamente por citar algunos de los retos que tiene. Algunas de estas demandas son complementarias, otras se contraponen, lo que hace valiosos a los estudios que desde las ciencias sociales se realizan y, desde diversas ópticas, se hagan propuestas de política pública balanceadas que consideren lo mejor de cada enfoque, pero sin desechar por completo los antagónicos.Universidad Autónoma Chaping

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
