[Impact of the "daily huddle" on the safety of pediatric hospitalized patients]. / Impacto de los «daily huddle¼ en la seguridad del paciente pediátrico hospitalizado.

INTRODUCTION: In 2017, the Joint Commission proposed daily meetings called "huddle" as an indicator of quality of care. They are brief daily meetings of the multidisciplinary team, where security problems of the last 24h are shared and risks are anticipated. The objectives were to describe the most frequent safety events in Pediatric wards, implement improvements in patient safety, improve team communication, implement international safety protocols, and measure the satisfaction of the staff involved. MATERIAL AND METHODS: Prospective, longitudinal and analytical design (June 2020-February 2022), with previous educational intervention. Safety incidents, data related to unequivocal identification, allergy and pain records, data from the Scale for the Early Detection of Deficiencies (SAPI) and the Scale for the Secure Transmission of Information (SBAR) were collected. The degree of satisfaction of the professionals was evaluated. RESULTS: Three hundred forty-eight security incidents were recorded. Medication prescription or administration errors stood out (n=103). Drug prescription or administration errors stood out (n=103), especially those related to high-risk medication: acetaminophen (n=14) (×10 doses of acetaminophen; n=6), insulin (n=6), potassium (n=5) and morphic (n=5). An improvement was observed in the pain record; 5% versus 80% (P<.01), in the SAPI registry 5% versus 70% (P<.01), in SBAER scale 40% vs 100% (P<.01), in unequivocal identification of the patient 80% versus 100%; (P<.01) and in the application of analgesic techniques 60% versus 85% (P=.01). In the survey of professionals, a degree of satisfaction of 8 (7-9.5)/10 was obtained. CONCLUSIONS: Huddles made it possible to learn about security events in our environment and increase the safety of hospitalized patients, and improved communication and the relationship of the multidisciplinary team.

Pre-cure freezing effect on physicochemical, texture and sensory characteristics of Iberian ham.

The aim of this work was to investigate the effect of pre-cure freezing on the physicochemical, texture and sensory characteristics of raw and dry-cured hams. Both, refrigerated (R) and pre-cure frozen (F) hams showed the same weight losses during the processing. At the green stage F Iberian hams had lower moisture content, higher values of a* and chroma, lower hardness and chewiness and higher adhesiveness and springiness than R ones. However, at the end of the processing R and F Iberian hams only were different in salt content, F hams showing lower values than R ones. Sensory analysis of Iberian dry-cured ham did not show differences in salty taste. Panelist detected a higher fat hardness and lean pastiness in F than in R hams. The overall acceptability for both groups of dry-cured hams was between average and good.

Nutritional treatment for ambulatory patients with acquired immunodeficiency virus infection and previous weight loss using a formula enriched with n3 fatty acids: a randomized prospective trial.

BACKGROUND AND AIMS: Dietary counseling and oral supplementation have unclear results in preventing the progressive weight loss in human deficiency virus (HIV)-infection. The aim of the study was to compare the progression of nutritional indicators with or without a formula enriched with n-3 fatty acids. PATIENTS AND METHODS: 30 HIV patients were enrolled. 15 were randomized to group I (standard formula) and 15 were randomized to group II (formula enriched with n-3 fatty acids). A nutritional evaluation was realized at basal time and at 3 months. RESULTS: An increase in protein and calories intakes was detected in both. There was a significant increase in n3 fatty acid intake from baseline in group II, without statistical changes in group I. Treatment with both supplements resulted in a significant and sustained increase in weight (4.5% in group I and 5.4%, in group II). This increase was mostly due to fat free mass in group I. In group II it was due to an increase in fat free mass and fat mass. CONCLUSIONS: Oral nutritional supplements for a 3-months period were well tolerated and resulted in body weight gain in HIV-infected patients with previous weight loss.

Comparison of different methods for total lipid quantification in meat and meat products.

This study was aimed to evaluate the efficiency of six extraction methods for the quantification of total lipid content in meat and meat products: standard Soxhlet method (with and without previous acid hydrolysis), continuous Soxhlet method (with and without previous acid hydrolysis), and those methods based in the use of a mixture of chloroform and methanol, and described by Folch, Less, and Sloane (1957) and Bligh and Dyer (1959). Lipid content was determined in nine different meat products with different fat contents and physico-chemical features: cooked turkey breast, fresh pork loin, cooked ham, dry-cured ham, mortadella, beef burger, fresh sausage, dry-cured sausage and salami. The most effective methods for determining fat content in the studied meat products were the method described by Folch et al. (1957) and the Soxhlet with previous acid hydrolysis method. The Soxhlet method without previous acid hydrolysis adequately extracted lipids only in those meat products with very high fat content. The use of the method described by Bligh and Dyer (1959) gave rise to the lowest lipid contents in all the studied meat products.

Repeated roll-to-roll transfer of two-dimensional materials by electrochemical delamination.

Two-dimensional (2D) materials such as graphene (Gr), molybdenum disulfide and hexagonal boron nitride (hBN) hold great promise for low-cost and ubiquitous electronics for flexible displays, solar cells or smart sensors. To implement this vision, scalable production, transfer and patterning technologies of 2D materials are needed. Recently, roll-to-roll (R2R) processing, a technique that is widely used in industry and known to be cost-effective and scalable, was applied to continuously grow and transfer graphene. However, more work is needed to understand the possibilities and limitations of this technology to make R2R processing of 2D materials feasible. In this work, we fabricated a custom R2R transferring system that allows the accurate control of the process parameters. We employ continuous electrochemical delamination, known as "bubble transfer", to eliminate chemical etchant waste and enable the continuous transfer of 2D materials from metal foils. This also makes our transfer method a renewable and environmentally friendly process. We investigate the surface topology as well as the electrical parameters of roll-to-roll transferred graphene on polyethylene terephthalate (PET) coated with ethylene-vinyl acetate (EVA). Furthermore, we demonstrate for the first time the stacking of two layers of graphene or graphene on hBN by repeated lamination and delamination onto EVA/PET. These results are an important contribution to creating low-cost, large scale and flexible electronics based on 2D materials.

High Temperature Terahertz Detectors Realized by a GaN High Electron Mobility Transistor.

In this work, a high temperature THz detector based on a GaN high electron mobility transistor (HEMT) with nano antenna structures was fabricated and demonstrated to be able to work up to 200 °C. The THz responsivity and noise equivalent power (NEP) of the device were characterized at 0.14 THz radiation over a wide temperature range from room temperature to 200 °C. A high responsivity Rv of 15.5 and 2.7 kV/W and a low NEP of 0.58 and 10 pW/Hz0.5 were obtained at room temperature and 200 °C, respectively. The advantages of the GaN HEMT over other types of field effect transistors for high temperature terahertz detection are discussed. The physical mechanisms responsible for the temperature dependence of the responsivity and NEP of the GaN HEMT are also analyzed thoroughly.

Aplicación de diferentes metodologías en el mejoramiento de lenteja (Lens culinaris Medik) / Application of different methodologies in lentil (Lens culinaris Medik) breeding

RESUMEN La lenteja (Lens culinaris Medik.) es una especie diploide autógama (2n=2x=14) perteneciente a la familia Fabaceae. Es uno de los cultivos más antiguos que se conocen, con 8.000 a 9.000 años de historia, y se encuentra entre los primeros domesticados en Medio Oriente. Las semillas tienen un alto valor nutricional. Este cultivo es un interesante sustituto del trigo en las rotaciones de cereales, pero su importancia es baja debido a la falta de buenas variedades con adaptación local. Uno de los principales problemas que enfrentan los mejoradores en nuestro país es la estrecha base genética del germoplasma cultivado y su bajo potencial de rendimiento. En 2004 se inició un programa de mejoramiento de lentejas para desarrollar nuevas variedades con adaptación a las condiciones predominantes en las áreas de cultivo de Argentina. El germoplasma se obtuvo del ICARDA (Centro Internacional de Investigación Agrícola en las Zonas Áridas) y de productores locales. Se utilizan métodos convencionales de mejoramiento basados en la hibridación y selección. Se han obtenido dos nuevas variedades, una del tipo macrosperma (Boyerito FCA) y la otra del tipo microsperma (Tacuarita FCA) mediante la aplicación de selección masal en poblaciones F2 provenientes de la hibridación de materiales seleccionados. Este programa complementa los métodos de mejora tradicional con técnicas biotecnológicas como la transgénesis, el uso de marcadores moleculares, el cultivo de embriones in vitro combinado con el método SSD para acortar el ciclo generacional, y el fenotipado digital.

ABSTRACT Lentil (Lens culinaris Medik.) is a self-pollinating diploid (2n=2x=14) species belonging to the Fabaceae family. It is one of the oldest crops known, with 8,000 to 9,000 years of history and it is among the earliest domesticates from the Near East Fertile Crescent. The seeds have high nutritional value. This crop is an interesting substitute to wheat in cereal rotations but its importance is low due to a lack of suitable varieties with local adaptation. Some of the major problems that Argentinian lentil breeders face are the narrow genetic base of the current cultivated germplasm and its low yield potential. A lentil breeding program was initiated in 2004 to develop new varieties with adaptation to prevalent conditions in growing areas of Argentina. Germplasm was obtained from ICARDA (International Center for Agricultural Research in the Dry Areas) and local producers. Conventional breeding methods using hybridization and selection are being carried out to develop improved varieties, broad the genetic base, and isolate superior recombinant inbred lines. Two new varieties have been obtained, one of the macrosperm type (Boyerito FCA) and the other of the microsperm type (Tacuarita FCA) through the application of mass selection in F2 populations from the cross of selected materials. This program complements traditional breeding methods with biotechnological techniques such as transgenesis, use of molecular markers, in vitro embryo culture combined with the SSD method to shorten the breeding time, and digital phenotyping.

Impact of cooking and handling conditions on furanic compounds in breaded fish products.

This study evaluates the influence of cooking and handling conditions on the quantity of furanic compounds (furan, 2-furfural, furfuryl alcohol, 2-pentylfuran, 5-hydroxymethylfurfural) in breaded fish products. Oven-baking and reheating in the microwave lead to low furanic compounds formation in comparison with deep-frying. The use of olive oil for deep-frying promoted higher levels of furanic compounds than sunflower oil. The amounts of these compounds diminished as the temperature and time of deep-frying decreased as well as after a delay after deep-frying. Thus, the generation of furanic compounds can be minimized by adjusting the cooking method and conditions, such as using an electric oven, deep-frying in sunflower oil at 160°C during 4min, or waiting 10min after cooking. However, these conditions that reduce furanic compounds levels also reduce the content of volatile compounds related to the aroma and flavour of fried foods. In this sense, new efforts should be done to reduce the formation of furanic compounds without being detrimental to the volatile profile.

Quantification of furanic compounds in coated deep-fried products simulating normal preparation and consumption: optimisation of HS-SPME analytical conditions by response surface methodology.

The validation of a method for the simultaneous quantification of furanic compounds in coated deep-fried samples processed and handled as usually consumed is presented. The deep-fried food was grinded using a device that simulates the mastication, and immediately analysed by headspace solid phase microextraction coupled to gas chromatography-mass spectrometry. Parameters affecting the efficiency of HS-SPME procedure were selected by response surface methodology, using a 2(3) full-factorial central composite design. Optimal conditions were achieved using 2g of sample, 3g of NaCl and 40min of absorption time at 37°C. Consistency between predicted and experimented values was observed and quality parameters of the method were established. As a result, furan, 2-furfural, furfuryl alcohol and 2-pentylfuran were, for the first time, simultaneously detected and quantified (5.59, 0.27, 10.48 and 1.77µgg(-1) sample, respectively) in coated deep-fried fish, contributing to a better understanding of the amounts of these compounds in food.

Effect of solvent to sample ratio on total lipid extracted and fatty acid composition in meat products within different fat content.

The effect of solvent to sample ratio on total extracted lipids and fatty acid (FA) composition in meat products with different fat contents was evaluated. Total lipids were extracted according to the Folch et al. (1957) method, using a 20:1 ratio of chloroform:methanol (2:1, v/v) to sample (A), and also testing the solvent:sample ratio of 10:1 (B). Higher amounts of total lipids and total FA from neutral lipids were obtained using the A ratio, which could be due to an insufficient chloroform:dry-weight sample proportion which could be insufficient for solubilizing the total amount of lipids. In the polar lipid fraction, the total amount of FA was higher using the B rather than the A ratio, which may be caused by the higher volume of added water when using A than B. When studying the FA composition of different lipid fractions, the volume of both the solvent and the water for total lipid extraction should be considered.

Hacia la construcción de las prácticas comunitarias de terapeutas ocupacionales en Chile, desde una mirada socio histórica, desde 1972 hasta la actualidad / Towards the construction of the occupational therapists community practices in Chile, from a social historic view, from 1972 until nowadays

Esta investigación, muestra la construcción de prácticas de Terapeutas Ocupacionales que, desde diversas perspectivas, han realizado trabajo comunitario en Chile, pretendiendo comprender su desarrollo en distintos contextos históricos desde 1972 hasta la actualidad, rescatando relatos en base a la experiencia, que den cuenta de la relación entre contextos socio históricos y prácticas comunitarias. La metodología utilizada para este estudio fue cualitativa. Se recopiló información mediante once entrevistas semiestructuradas y un grupo de discusión. Posteriormente, se analizó la información a través de Teoría Fundada, en diferentes categorías, abierta y axial con un eje central en discusión con planteamientos teóricos. Los hallazgos de este estudio, permiten concluir que los contextos socio históricos determinan las formas de hacer prácticas comunitarias en Chile; y éstas, a su vez, influyen en la interacción con la comunidad favoreciendo o dificultando su participación social. El Terapeuta Ocupacional es parte de ese contexto sociohistórico por lo que su identidad, equipo de trabajo y su práctica comunitaria está configurada y construida desde ahí, sin embargo, el no hacer consciente sus prácticas y cómo éstas se han construido, no permitiría establecer la dimensión política de su hacer. Ocuparse de la ocupación, junto con la cotidianeidad en el campo comunitario implica una comprensión de la realidad socio-histórica, determinando las prácticas comunitarias de los Terapeutas Ocupacionales así como la construcción de comunidad.

This investigation will show the process of constructing Occupational Therapy practices that have been realized from various perspectives via community work in Chile, attempting to understand its development in the different social and historical periods since 1972 until the present time, emphasizing experience accounts, wich make clear the relation between social and historical contexts and practices. The methodology employed in this work was qualitative with information based on eleven semi-structured interviews and a discussion group. The information was analyzed using the Grounded Theory, through opened and axial categories, related to a central theoretical axis. The findings conclude that the social and historical contexts determine the way of doing community practice in Chile, and these affect the interaction with community, favoring or making difficult their social participation. The therapist is part of that social and historical context. Therefore, his identity, work team and community practice are constructed there. Nevertheless, if he does not become conscious of his practice and how it has been constructed, he will not build the political dimension of his work. To be in charge of daily occupation in the community field involves an understanding of the social and historical reality, determining the community practices of the Occupational Therapists and likewise the construction of community.

Significados asociados a la actividad delictiva en hombres que se encuentran privados de libertad, en Centro de Detención Preventiva Santiago Sur / Meanings associated to criminal activities in men who are deprived of their liberty, in Centro de Detencion Preventiva Santiago Sur

El presente estudio pretende comprender los significados que las personas transgresoras de ley, le otorgan a su propia actividad delictiva, específicamente al robo, mediante la identificación y relación de los temas emergentes durante este estudio, con constructos teóricos. La identificación y comprensión de estos temas, se realiza en torno a una visión general de Terapia Ocupacional. Para abordar esta investigación, de carácter cualitativo, se contextualiza el tema a estudiar en Centro de Detención Preventiva Santiago Sur, siendo los participantes hombres entre 27 y 35 años, que cumplen condena por delito de robo. La información recopilada, se extrae a partir de cinco entrevistas semi estructuradas, para ser luego analizadas a través de la Teoría Fundada, que permite revisar los fenómenos emergentes y ponerlos en discusión con los planteamientos teóricos. Los hallazgos obtenidos, señalan que los significados asociados al robo, se pueden relacionar a distintos fenómenos como; factores psicosociales de riesgo, inicio delictual e influencia y pertenencia a redes sociales, conducta exploratoria, procesos psicosociales, interacción simbólica y mapa significativo propio, identidad personal, acción preconcebida y motivaciones del robo, autoconcepto y autoeficacia.

The following Seminar is orientated to understand the meanings that people outside the law give to their own criminal activities, primarily stealing, through the identification and connection between the emerging issues and the theoretical constructs made through this study. The identification and understanding of this topic is developed focusing on Occupational Therapy general views. To develop this qualitative research, the project takes place in Centro de Detención Preventiva ( Preventive detention center) Santiago Sur, Chile, with men between the ages of 27 and 35 years old, which are convicted for robbery. The information was collected from five semi-structured interviews, and analyzed with the Grounded Theory. This allows the review of emerging phenomena and compares them with the theoretical approach. The results indicate that the meanings related to stealing are correlated with different phenomena, like: psychosocial risk factors, criminal initiation and the influence of being part of social networks, exploratory behavior, psychosocial development, symbolic interaction and meaningful map, personal identity, premeditated action and motivation for stealing, self-concept and self-efficiency. After discovering and understanding the phenomena from the participant’s point of view, it is clear to see two different ways for understanding the act of stealing, which differ from the meaning that the person gives to the act. On one hand, they see themselves as thieves and participate with the role. And on the other, they do not see themselves as thieves, they find an identity with the job, becoming the main activity in their lives. The analysis and results of the meanings associated to the act of robbery can be interesting for Occupational Therapy. This research includes key elements for this discipline and its development, including the motivation and personal subjectivity, bounds, relationships and the context for their development, making all together the...
