RESUMO

La Medicina Natural y Tradicional aplica sus diferentes modalidades en la práctica médica moderna, segura, económica, inocua y simple; y con pocos efectos colaterales resuelve grandes problemas de salud en situaciones especiales o de desastres con recursos limitados. De ahí que el egresado de programas de especialización de las ciencias médicas cuenta con sólidos conocimientos para su aplicación, especialmente en las afecciones osteomioarticulares, donde la especialidad de ortopedia y traumatología tiene un papel primordial para identificar las causas y consecuencias de la insuficiencia de su aplicación en pacientes portadores de afecciones relacionadas con esta especialidad. A través de un estudio crítico reflexivo basado en el análisis y la síntesis, así como de la constatación de la validez de los puntos de vista asumidos como referentes en el proceso de superación del especialista de ortopedia y traumatología, se pudo mostrar cómo se ha concebido la superación profesional en el Hospital General Dr. Juan Bruno Zayas Alfonso, al integrar adecuadamente los conocimientos y las competencias. Esto se expresó en la elaboración e implementación de una estrategia de superación profesional, que permitió la actualización de relevantes conocimientos necesarios en el campo de la MNT para el desempeño de este profesional. Se concluyó que era insuficiente el nivel de conocimiento de los contenidos, como también los cursos ofertados para su desarrollo, lo que trajo como consecuencia una atención médica sin calidad(AU)

Natural and traditional medicine applies its different modalities in modern, safe, economical, innocuous and simple medical practice; with few collateral effects, it solves major health problems in special or disaster situations with limited resources. Hence, the graduate of specialization programs in medical sciences possesses solid knowledge for its application, especially in osteomyoarticular conditions, in which the specialty of orthopedics and traumatology has a key role in identifying the causes and consequences of its unsatisfactory application in patients with conditions related to this specialty. Through a reflexive and critical study based on analysis and synthesis, as well as the verification of the validity of the viewpoints assumed as referents in the process of improvement of the orthopedics and traumatology specialist, it was possible to show how professional improvement has been conceived at Hospital General Dr. Juan Bruno Zayas Alfonso, by adequately integrating knowledge and competences. This was expressed through the elaboration and implementation of a professional improvement strategy, which allowed updating relevant knowledge necessary in the field of natural and traditional medicine for the performance of this professional. The level of knowledge about the contents was concluded to be insufficient, while the courses offered for its development were so, which resulted in a medical care without quality(AU)

RESUMO

The objective of this study is to compare the environmental and social performance of two small-scale avocado biorefineries implanted in a rural zone in the North of Colombia. Two small-scale biorefineries were proposed. Small-B1 addressed to produce avocado oil and animal feed, and Small-B2 focused on the guacamole production. The environmental analysis was done by applying the life cycle assessment methodology. Then, agronomic information and process simulation were required to complete the analysis. Moreover, the water footprint of the avocado crops was estimated. Both biorefineries were compared with the direct avocados production and commercialization. The social assessment was achieved by the estimation of quantitative indicators related to wages, jobs, and working hours. The agricultural carbon and water footprints of the creole avocado crop were 0.59 kg CO2-eq/kg and 2.13 m3/kg. In the same way, Small-B1 and Small-B2 obtained a carbon and water footprints of 8.99 kg CO2-eq/kg and 6.63 m3/kg and 0.72 kg CO2-eq/kg and 1.38 m3/kg, respectively. The hotspots of the creole avocado crop are related to the use of fertilizers and fungicides. Then, new strategies should be implemented to reduce the farmer's dependency. The social analysis exhibit a high resilience of the Small-B1 biorefinery since a salary increase to worker about 50% can be proposed. In addition, the installation of this biorefinery can create more than ten jobs. A disjunction was found between the economic, environmental, and social analyses. Thus, the need to establish a multidimensional strategy to design sustainable biorefineries is presented.

RESUMO

La enseñanza de las ciencias básicas en las universidades médicas constituye una prioridad para la formación del profesional de la salud, porque ofrece los fundamentos teóricos que propician la comprensión de la morfofisiología del organismo humano, sus interdependencias y sus relaciones con el medio en que nace, crece, se desarrolla y muere. En tal sentido, se deriva la necesidad de mantener la superación de los docentes para el perfeccionamiento de la dirección del proceso de enseñanza-aprendizaje desde los primeros años de la carrera de medicina y en esta investigación, en particular, en el uso del dibujo de imágenes microscópicas para la enseñanza de estos conocimientos en la disciplina Bases Biológicas de la Medicina. El objetivo del artículo fue caracterizar la superación pedagógica de los profesores de Histología en la Universidad de Ciencias Médicas de Matanzas. Se realizó una revisión bibliográfica de artículos que abordaban esta temática, así como de documentos normativos para la formación de los docentes en esta área pedagógica. Se identificaron tres momentos que caracterizaban la trayectoria de la superación pedagógica de los profesores de las ciencias biomédicas; en particular, el papel del dibujo de imágenes microscópicas como medio de enseñanza en ese proceso. Se consideró que no se dedicaba tiempo en los programas a su desarrollo, por lo que se deriva la necesidad de la superación profesoral y el perfeccionamiento de la didáctica de esta disciplina(AU)

RESUMO

This research paper seeks to evaluate the influence of the context, processing scale, and portfolio of products on the economic performance of different avocado-based biorefineries. For this, two scenarios in small and large-scale biorefineries were compared. The case of scenario 1 (avocado oil, animal feed, and electricity production) was the best small-scale alternative to be implemented in rural zones than scenario 2 (guacamole and electricity production). The minimum Processing Scale for Economic Feasibility was 0.85 and 1.1 ton/day for scenarios 1 and 2. Compared to lactic acid and xylitol production, the large-scale process addressed to produce levulinic acid, furfural, and lignin (scenario 1) was the best option (scenario 2). In scenario 1, the minimum Processing Scale for Economic Feasibility was 15.50 ton/day compared with scenario 2 of 41.95 ton/day. Based on these values, scenario 1 has the highest feasibility of being implemented in countries such as Colombia.

RESUMO

The hydrodeoxygenation (HDO) of acetophenone was evaluated in liquid phase and gas phase over monometallic Pt/SiO2, Co/SiO2 and bimetallic Pt-Co/SiO2 catalysts. The influence of reaction time and loading of the catalyst were analysed by following the conversion and products selectivity. Phenylethanol, cyclohexylethanone and cyclohexylethanol are the main products of reaction using the Pt/SiO2 catalyst. By contrast, ethylbenzene and phenylethanol are the only products formed on the Co/SiO2 and Pt-Co/SiO2 catalysts. The bimetallic catalyst is more stable as a function of time and more active towards the HDO process than the monometallic systems. The presence of an organic solvent showed only minor changes in product yields with no effect on the product speciation. Periodic density functional theory analysis indicates a stronger interaction between the carbonyl group of acetophenone with Co than with Pt sites of the mono and bimetallic systems, indicating a key activity of oxophilic sites towards improved selectivity to deoxygenated products. This article is part of the theme issue 'Bio-derived and bioinspired sustainable advanced materials for emerging technologies (part 2)'.

RESUMO

La Escuela Nacional de Salud Pública ha contribuido de forma sustancial a la formación de los recursos humanos en las áreas académicas y profesionales del sistema de salud cubano, a través del desarrollo de un amplio programa de formación académica de posgrado y de superación profesional; esta última caracterizada por el desarrollo de cursos, entrenamientos, diplomados, talleres, conferencias y otras formas que generan en la institución gran número de actividades de superación. Este cúmulo de actividades presenta insuficiencias en su gestión y están desprovistas de tecnologías informáticas, que brindarían mejoras en su desempeño. Por tales motivos se realizó una investigación de desarrollo tecnológico con el objetivo de diseñar un sistema web para la gestión de actividades de superación profesional en la Escuela Nacional de Salud Pública en el año 2019. Se empleó la metodología de desarrollo de software AUP-UCI, el entorno de trabajo Vue.js escrito en lenguaje de programación JavaScript, se utilizó MongoDB como gestor de base de datos, y la herramienta Case Visual Paradigm de Lenguaje Unificado de Modelado. Se implementaron algunas funcionalidades del sistema, que se encuentra listo para fase de despliegue. El sistema satisface las necesidades de información para el proceso de superación profesional en la institución, favorece la toma de decisiones de los directivos, docentes, y usuarios vinculados en el proceso, además muestra gran factibilidad su aplicación y extensión a otras instituciones de posgrado de la educación superior de salud y otros sectores(AU)

The National School of Public Health has contributed substantially to the training of human resources in the academic and professional areas of the Cuban health system, due to the development of an extensive program of academic postgraduate training and professional upgrading. The latter is characterized by the expansion of courses, trainings, diplomas, workshops, conferences and others, generating numerous professional development activities in the institution, all of them with insufficiencies in their management and devoid of computer technologies to provide improvements in their performance. For these reasons, a technological development research was carried out in 2019 with the aim of designing a web system for the management of professional development activities at the National School of Public Health. The AUP-UCI software development methodology was used, the Vue.js working environment written in JavaScript programming language and MongoDB as the database manager, and the Case Visual Paradigm tool of Unified Modeling Language. Some functionalities of the system were implemented, which are ready for the deployment phase. The proposed system satisfies the information needs for the improvement of professional upgrading in the institution, favors decision-making by managers, professors, and users linked to the process, shows great feasibility of its application and extension to other postgraduate educational institutions in health and other sectors(AU)

RESUMO

The influence of two autochthonous lactobacilli strains with probiotic potential (Lactobacillus mucosae CNPC007 and Lactobacillus plantarum CNPC020) in comparison to a commercially available probiotic strain (Lactobacillus rhamnosus LR32) in non-fermented dairy desserts added with ingredients (syrup and hydroethanolic extract) derived from jabuticaba (Myrciaria cauliflora) peels was investigated. L. mucosae showed the best survivability and stability of the studied lactobacilli after processing and during storage, respectively, and also remarkably influenced the texture and sensory features of desserts in comparison to the other strains; L. plantarum achieved viability comparable with the commercial probiotic, above 6 log cfu/g up to the 21st day of the products refrigerated storage. The hydroethanolic extract and syrup from the jabuticaba peel contributed to the phenolic content of the dairy desserts (around 30 mg GAE/100 g) that showed to be able to scavenge DPPH radicals (around 300 g dessert/g DPPH). The different lactobacilli strains did not significantly influence the antioxidant capacity parameters of the desserts (p > 0.05), although the desserts' color was not stable during storage and tended to reduce the acceptability scores of the three trials. Non-fermented dairy desserts with jabuticaba peel ingredients showed to be good sources of phenolic compounds with an antioxidant capacity, offering suitable conditions for the viability maintenance of the autochthonous lactobacilli cultures.

RESUMO

This meta-analysis focuses on the accuracy of upgrading to clinically significant prostate cancer (PCa) by multiparametric magnetic resonance imaging-targeted biopsy (MRI-TB) versus systematic biopsy (SB). We searched the Medline, Embase, Cochrane Central Register of Controlled Trials, Web of Science, Scopus, and Literatura Latino Americana em Ciências da Saúde databases through January 2020 for comparative, retrospective/prospective, paired-cohort, and randomized clinical trials with paired comparisons. The population consisted of patients with low-risk PCa in active surveillance with at least 1 index lesion on imaging. We evaluated the quality of evidence by using the Quality Assessment of Diagnostic Accuracy Studies-2 score. Group comparisons considered the differences between the area under the curve summary receiver operating characteristic curve in a 2-tailed method. We also compared the positive predictive value of the best single method (MRI-TB or SB) and the referral study test (combined biopsy, a combination of MRI-TB and SB). The meta-analysis included 6 studies enrolling 741 patients. The pooled sensitivity for the 2 groups was 0.79 (95% confidence interval, 0.74-0.83; I2 = 75%) and 0.67 (95% confidence interval, 0.63-0.74; I2 = 55.4%), respectively. The area under the curve for the MRI-TB and SB groups were 0.99 and 0.92 (P < .001), respectively. The positive predictive value for the MRI-TB and combined biopsy groups were similar. The accumulated evidence suggests better results for MRI-TB compared with SB. Therefore, use of MRI-TB alone may be preferable in patients in active surveillance harboring low-risk PCa.

RESUMO

BACKGROUND: We compared upgrading and upstaging rates in low risk and favorable intermediate risk prostate cancer (CaP) patients according to racial and/or ethnic group: Mexican-Americans and Caucasians. METHODS: Within Surveillance, Epidemiology and End Results database (2010-2015), we identified low risk and favorable intermediate risk CaP patients according to National Comprehensive Cancer Network guidelines. Descriptives and logistic regression models were used. Furthermore, a subgroup analysis was performed to test the association between Mexican-American vs. Caucasian racial and/or ethnic groups and upgrading either to Gleason-Grade Group (GGG II) or to GGG III, IV or V, in low risk or favorable intermediate risk CaP patients, respectively. RESULTS: We identified 673 (2.6%) Mexican-American and 24,959 (97.4%) Caucasian CaP patients. Of those, 14,789 were low risk (434 [2.9%] Mexican-Americans vs. 14,355 [97.1%] Caucasians) and 10,834 were favorable intermediate risk (239 [2.2%] Mexican-Americans vs. 10,604 [97.8%] Caucasians). In low risk CaP patients, Mexican-American vs. Caucasian racial and/or ethnic group did not result in either upgrading or upstaging differences. However, in favorable intermediate risk CaP patients, upgrading rate was higher in Mexican-Americans than in Caucasians (31.4 vs. 25.5%, OR 1.33, P = 0.044), but no difference was recorded for upstaging. When comparisons focused on upgrading to GGG III, IV or V, higher rate was recorded in Mexican-American relative to Caucasian favorable intermediate risk CaP patients (20.4 vs. 15.4%, OR 1.41, P = 0.034). CONCLUSION: Low risk Mexican-American CaP patients do not differ from low risk Caucasian CaP patients. However, favorable intermediate risk Mexican-American CaP patients exhibit higher rates of upgrading than their Caucasian counterparts. This information should be considered at treatment decision making.

RESUMO

Energy-driven biorefineries can be designed considering biotechnological and thermochemical conversion pathways. Nevertheless, energy and environmental comparisons are necessary to establish the best way to upgrade lignocellulosic biomass and set the requirements of these processes in different scenarios. This paper aims to evaluate experimentally a biorefinery producing energy vectors using coffee-cut stems (CCS) as feedstock. The obtained yields were the basis for energy and environmental analysis, in two different biorefinery scenarios: (i) production of bioethanol and biogas and (ii) production of syngas and electricity. The energy results indicated that the overall energy efficiency calculated in the first scenario was only 9.15%. Meanwhile, the second biorefinery configuration based on thermochemical routes presented an energy efficiency value of 70.89%. This difference was attributed to the higher consumption of utilities in the biorefinery based on biotechnological routes. The environmental results showed that the impact category of climate change for the first biorefinery (i.e., 0.0193 kg CO2 eq./MJ) had a lower value than that of the second process (i.e., 0.2377 kg CO2 eq./MJ). Thus, the biorefinery based on the biotechnological route presented a better environmental performance. Additionally, the results for both biorefineries allowed concluding that the inclusion of by-products and co-products in the calculation of the environmental analysis can dramatically affect the results.

RESUMO

Microalgae-bacteria consortium based technology using a High Rate Algal Pond (HRAP) interconnected to an Absorption Bubble Column (ABC) has emerged as an environmentally friendly promising option to upgrade biogas. However, the oxygenic photosynthesis of microalgae induces oxygen contamination in upgraded biogas, which could limit its further applications. Several strategies were proposed to favor the oxygen desorption and oxygen uptake in parts and accessories of the upgrading system. The effect of the volumetric ratio liquid recirculation rate/biogas rate (L/G = 5.0, 1.0 y 0.5) was evaluated in conjunction with the application of a novel accessory called Open Trickling Column (OTC). The O2 content in upgraded biogas was around 2.1%v, attaining CO2 removal efficiencies around 90%, at L/G ratio of 1.0 during diurnal and nocturnal periods. The inclusion of an OTC at the previous L/G, enhanced 54% the removal of O2 by stripping and uptake compared with the basal condition. Mass balances of H2S and methane showed that L/G > 1.0 favored the complete oxidation of H2S but promoted the loss of methane in dissolved form. Additionally the effect of increasing linear velocity of liquid broth in the lab-scale HRAP (from 15 cm s-1 to 20 cm s-1) showed to improve the O2 stripping with a consequential increase of biomass concentration under steady-state (from 0.7 to 1.4 g L-1) besides achieving O2 content in the upgraded biogas around 1.5%v.

RESUMO

A type 1 reaction (T1R) is also known as a reversal reaction. This phenomenon involves exarcebation of the immune system or delayed-type hypersensitivity in response to the antigens of Mycobacterium leprae present in parasitized tissues. It occurs in mnost patients of the tuberculoid and borderline forms of the Ridley & Jopling classification for leprosy. It is an important phenomenon that can occur before, during, or after leprosy treatment and can be destructive, causing tissue damage mainly in the nerves, as well as irreversible sequelae. The recognition of T1R in histological sections may be notified prior to clinical presentation. Histopathological recognition is vital in defining or confirming the presence of T1R, guiding the treatment of the reaction process, avoiding or reducing the possibiliy of serious sequelae, correcting possible mistakes in the classification of patients within the spectrum of leprosy, and ruling out other diseases that can clinically simulate a T1R. In this chapter, the histopathological characteristics that allow the recognition of T1R, various histopathological aspects of the common forms of leprosy, and histopathological differential diagnoses are discussed.
