De NovoSan Luis Valley Syndrome-like der(8) Chromosome With a Concomitant dup(8p22) in a Mexican Girl

The rec(8)dup(8q)inv(8)(p23.1q22.1) chromosome associated with San Luis Valley Syndrome (SLVS OMIM 179613) is usually diagnosed in Hispanic patients from the USA Southwest where a founder carrier Spaniard lived around 1800 [1, 2]. This rec(8) has an 8q duplication of 47.90 Mb and an 8p deletion of 11.65 Mb [3, 4]. Excluding two de novo rec(8)dup q chromosomes characterized only by G-bands and included in a recent compilation [5], cytogenomic analyses identified nine comparable de novo der(8)dup q/del p chromosomes with or without a simultaneous 8p gain. We describe a Mexican mestizo girl with a de novo SLVS-like der(8) but with a concomitant 8p22p23.1 duplicatio

Cambra system in patients awaiting hematopoietic progenitor cell transplant and high caries risk

Recent times have witnessed a significant increase in the number of patients affected by problems related to oncological treatment Aims of this study is to evaluate dental affectation among patients awaiting hematopoietic progenitor cell transplant (HPCT), and they showed high caries risk, so it should establish a protocol prior to transplantation. The study included 72 patients due for HPCT. Clinical and radiological explorations were performed and oral photos taken. The amount of caries, missing teeth and fillings were registered for each patient. CAO, DMFS and Restoration Indices were calculated. 83% of patients presented caries. 48 patients (67%) had lost at least one tooth. Only 32 patients (44%) had received some sort of conservative treatment. The average CAO index value obtained was 10.37. The DMFS index showed an average of 27.06 affected surfaces. Of the 72 patients studied, 40 (56%) showed a restoration index value of zero. These patients presented a high number of carious teeth and a low restoration index. The presence of so many possible septic foci in an individual, who will later become susceptible to infection, highlights the importance of preventative treatment and bucco-dental restoration within this patient population. These patients with a high caries risk can be treated with CAMBRA system

RESPUESTA DE HÍBRIDOS DE CHILE ANAHEIM (CAPSICUM ANNUUM L.) CARDÓN Y 118, CULTIVADOS BAJO DOS SISTEMAS DE PRODUCCIÓN EN CONDICIONES DE INVERNADERO

The production system under greenhouse makes possible to obtain higher yields and better fruit quality. Two Anaheim pepper hybrids were produced during summer-fall season of 2011 at the experimental field of the University of Sonora, México. The objectives were to evaluate the yield and fruit quality, and to determine the water use efficiency, under greenhouse conditions using two production systems, substrate and soil. In the soil system the higher fruit weights were obtained with 63.12 g fruit-1 and 61.98 g fruit-1, in Cardon and 118 respectively. The fruit number per plant and the yield in the first harvest were higher in the substrate system; however, the final averages were no significant among treatments. The higher fruit length, 17.52 and 15.52 cm in Cardon and 118 respectively, were obtained in the soil system. The fruit diameter did not present significant differences among treatments. The water use efficiency (WUE) was higher in the soil system, with 36.4 and 31.2 kg m-3 compared to 9.1 y 9.9 kg m-3 obtained in the substrate system for 118 and Cardon respectively

Hydrogen recovery from waste gas streams to feed (High-temperature PEM) fuel cells: environmental performance under a life-cycle thinking approach

Fossil fuels are being progressively substituted by a cleaner and more environmentally friendly form of energy, where hydrogen fuel cells stand out. However, the implementation of a competitive hydrogen economy still presents several challenges related to economic costs, required infrastructures, and environmental performance. In this context, the objective of this work is to determine the environmental performance of the recovery of hydrogen from industrial waste gas streams to feed high-temperature proton exchange membrane fuel cells for stationary applications. The life-cycle assessment (LCA) analyzed alternative scenarios with different process configurations, considering as functional unit 1 kg of hydrogen produced, 1 kWh of energy obtained, and 1 kg of inlet flow. The results make the recovery of hydrogen from waste streams environmentally preferable over alternative processes like methane reforming or coal gasification. The production of the fuel cell device resulted in high contributions in the abiotic depletion potential and acidification potential, mainly due to the presence of platinum metal in the anode and cathode. The design and operation conditions that defined a more favorable scenario are the availability of a pressurized waste gas stream, the use of photovoltaic electricity, and the implementation of an energy recovery system for the residual methane stream.The authors are grateful for the funding of the Spanish Ministry of Economy and Competitiveness through the Ceres-Procom Project CTM2016-76176 (AEI/FEDER, UE) and the funding of European Union through the Project SOE1/P1/E0293 (INTERREG SUDOE/FEDER, UE), “Energy Sustainability at the Sudoe Region: Red PEMFC-Sudoe”

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Gestión del conocimiento. Perspectiva multidisciplinaria. Volumen 7

El libro “Gestión del Conocimiento. Perspectiva Multidisciplinaria”, volumen 7, de la Colección Unión Global, es resultado de investigaciones. Los capítulos del libro, son resultados de investigaciones desarrolladas por sus autores. El libro es una publicación internacional, seriada, continua, arbitrada de acceso abierto a todas las áreas del conocimiento, que cuenta con el esfuerzo de investigadores de varios países del mundo, orientada a contribuir con procesos de gestión del conocimiento científico, tecnológico y humanístico que consoliden la transformación del conocimiento en diferentes escenarios, tanto organizacionales como universitarios, para el desarrollo de habilidades cognitivas del quehacer diario. La gestión del conocimiento es un camino para consolidar una plataforma en las empresas públicas o privadas, entidades educativas, organizaciones no gubernamentales, ya sea generando políticas para todas las jerarquías o un modelo de gestión para la administración, donde es fundamental articular el conocimiento, los trabajadores, directivos, el espacio de trabajo, hacia la creación de ambientes propicios para el desarrollo integral de las instituciones
