Authors: Macías Vera María Yessenia , Corral Mendoza Carlos Eduardo , Izurieta Rubira Ligia María 
Published: May 2020

El presente artículo, se suscribe en la modalidad de ensayo, el cual tiene como propósito realizar una contribución crítica y reflexiva en torno a la educación ambiental como herramienta estratégica para fomentar el turismo sostenible en la ciudad de Manta Ecuador, dicho recorrido discursivo inicia con una mirada hacia los aportes y preceptos que han realizado los organismos internacionales en torno a la temática, de allí que se aprecia que el turismo sostenible es crucial para el desarrollo, no solo porque encierra el potencial de contribuir al crecimiento económico, sino que también puede ejercer una influencia positiva en las comunidades locales; preservar el patrimonio, la biodiversidad y los recursos naturales. En este sentido se asume que la educación ambiental es una herramienta para mejorar las relaciones de los seres humanos con su medio y, por lo tanto, debe incidir en la prevención y resolución de problemas ambientales. Como reflexión, es imperativo que se asuma un currículo educativo contextualizado, que incluya la educación ambiental como la herramienta para impulsar el turismo sostenible, donde los docentes desarrollen estrategias con mayores niveles de concreción y con una postura socio crítica más cónsona con las demandas sociales y ambientales de la localidad.

Published: May 2020

Background: Currently, pulse pressure variation (PPV) is considered the gold standard dynamic variable for predicting fluid responsiveness. Distensibility index of inferior vena cava (dIVC) is also considered a good predictor of fluid responsiveness. However, information from literature comparing the performance of both variables is still patchy and insufficient. Therefore, we aimed to investigate the accuracy of dIVC and PPV in predicting fluid responsiveness and compare the predictive power of both techniques. Methods: We conducted our study in shocked patients receiving mechanical ventilation requiring fluid challenge. Hemodynamic variables, such as PPV and dIVC, were recorded before and after fluid challenges. Fluid responders were identified when cardiac output increased more than 15% after the first fluid challenge. Only the non-responders received a second fluid challenge (SFC) to define delayed responders. Results: A total of 38 shocked patients were enrolled in this study. Twenty-one patients (55.3%) were fluid responders. The area under the receiver operating characteristic (AUROC) curve of PPV was 0.78 ± 0.08 with a best cutoff of 10.5 (sensitivity: 76.2%; specificity: 70.6%). The AUROC curve of dIVC was 0.75 ± 0.07, and the best cutoff value to predict fluid responsiveness was 16.5% with a sensitivity of 71.43% and specificity of 76.5%. Four patients from the non-responder group became responders after the SFC. No statistically significant difference was observed between the predictive performance of PPV and dIVC. Conclusions: Our findings indicate that the performance of PPV for predicting fluid responsiveness was similar to that of dIVC. PPV and dIVC are moderately predictive of fluid responsiveness.
Dona-Arbre [Mujer-Árbol] de Fina Miralles: Recolectando conocimiento corporal.
Authors: Vara Celia 
Published: May 2020

En este artículo sostengo que Dona-Arbre [Mujer-Árbol] de Fina Miralles, de la serie Traslacions, es parte de una secuencia de ejercicios y prácticas experimentadas durante las acciones realizadas en las que el cuerpo se percibe y experimenta cada vez más. Todas estas acciones son ejercicios para buscar el cuerpo en conexion con su entorno y con ella misma. Esta acción precede un trabajo que más adelante se centra en el cuerpo y que puede leerse como más abiertamente feminista. Mi argumento es que con Dona-Arbre comienza un método exploratorio del cuerpo y del entorno, y que este método es valioso para un feminismo basado en un autoconocimiento somático. Partiendo de metodologías encarnadas, investigación-creación y empatía kinestésica, utilizo teorías feministas encarnadas y de agencia, y tomo el concepto de kinestesia de Carrie Noland para describir las estrategias específicas en Dona-Arbre tales como el cuerpo inmóvil, kinestesia y micro-movimientos. Los interpreto como resistencias sutiles e instrumentos fundamentales para construir agencia corporal en el contexto de las restricciones políticas del cuerpo durante la dictadura franquista.
In this article I claim that Dona-Arbre [Woman-Tree] by Fina Miralles from the series Traslacions, is part from a sequence of exercises and practices experienced during her performance work in which the body is increasingly perceived and experienced. All them are exercises in a search for the body in connection with its environment and with herself. It precedes her later focus on the body where there is a more overtly feminist political intervention. I argue that an exploratory method of the environment and the body starts with Dona-Arbre, and that this method is valuable to a feminist politics that begins from a somatic self-knowledge. Based on embodied methodologies, research-creation and kinestheticempathy, I engage with feminist theories of embodiment and agency, and take on Carrie Noland’s concept of kinesthesia to elaborate on the specific strategies in Dona-Arbre such as the still body, kinesthesia and micro-movements. I read them as a subtle resistance and pivotal instruments for building corporeal agency in the context of the acute restrictions on body politics during the Franco dictatorship.
Dificultades en el registro y transmisión de un arte fugaz.
Authors: Mateo Sánchez Cecila 
Published: May 2020

Desde la segunda mitad del siglo XX las intervenciones artísticas se independizan de los hartados y constantes componentes estéticos, miméticos y matéricos. La imposibilidad de custodiar la obra como objeto demanda nuevos mecanismos que registren un arte tan cambiante como caprichoso. Con los avances de la tecnología, la fotografía digital y las innovaciones acontecidas en el campo del arte, los artistas comenzarán a dejar constancia de sus intervenciones haciendo uso de cámaras fotográficas y pequeñas grabaciones para inmortalizar sus obras. Destinamos esta investigación a trabajar, a través de una representación de autores emergentes, las dificultades en el registro de obras artísticas caracterizadas por su intangibilidad.
El desafío está servido, cualquier persona o entidad vinculada a lo artístico se enfrenta a la difícil tarea de registrar para conservar la inmortalidad del acontecimiento artístico. Estas innovadoras y fugaces categorías llevan implícita la condición participativa del espectador, el espacio como continente y contenido de la obra, el tiempo, la extinción de los materiales, la acción, el desplazamiento, la pérdida de la unicidad del arte, así como su acelerada mortalidad. Condiciones y aspectos que hacen del arte un “arte-acontecimiento”, predispuesto por la condición espaciotemporal a su caducidad, modificación o desaparición.
Since the second half of 20th century, artistic interventions have become independent of the jaded and constant aesthetic, mimetic and mathematical components. The impossibility of guarding the work as an object demands new mechanisms that register an art as changing as it is capricious. With the advances in technology, digital photography and innovations in the field of art, artists will begin to record their interventions, using cameras and small recordings to immortalize their works. We dedicate this research to work through a representation of emerging authors, difficulties in the registration of artistic works characterized by their intangibility.
The challenge is served, any person or entity linked to the artistic, faces the difficult task of registering to preserve the immortality of the artistic event. These innovative and fleeting categories implicitly involve the participatory condition of the viewer, space as a continent and content of the work, time, extinction of materials, action, displacement, loss of the uniqueness of art, as well as its accelerated dematerialization Conditions and aspects that make art an “art-event”, predisposed by the space-time condition to its expiration, modification or disappearance.

Published: May 2020

BackgroundEpidermal growth factor (EGF) is a pro-inflammatory small peptide that stimulates cell growth, proliferation and differentiation through binding to its receptor.EGFrs2237051 and serum EGF levels have been demonstrated to be related with a variety of diseases, including several tumors and inflammatory diseases. Therefore, this study aims to investigate the association of theEGFrs2237051 variant and serum EGF levels in Chinese patients with generalized aggressive periodontitis (GAgP).Material and MethodsA case-control study was conducted among 216 patients with GAgP and 138 healthy controls. The clinical parameters of plaque index, probing depth, attachment loss and bleeding index were recorded. TheEGF rs2237051polymorphism was genotyped using time-of-flight mass spectrometry, and serum EGF levels were determined. Logistic and linear regression models were used to investigate the association between the genotypes ofEGFrs2237051, serum EGF levels and GAgP risk.ResultsThe AA genotype ofEGFrs2237051 showed higher risk for GAgP than the combined genotypes GG and AG (adjusted OR = 1.65, 95% CI [1.06–2.57]). Increased serum EGF levels were associated with GAgP (adjusted OR = 1.18, 95% CI [1.14–1.22]). Moreover, the serum EGF level for the AA genotype was significantly higher than that for the AG/GG genotypes in patients with GAgP (adjusted β = 4.70, 95% CI [2.09–7.31]).ConclusionWe demonstrated thatEGFrs2237051 variant and the increased level of serum EGF were associated with the risk of GAgP, the serum EGF was up-regulated in patients with GAgP. It was indicated that serum EGF might be a biomarker of GAgP andEGFrs2237051 may be related to the genetic background of GAgP.

Introduction: Malnutrition remains a childhood scourge in Sub Saharan Africa, Southern Africa, Zimbabwe and in the Insiza District, in particular. The district is rich in mineral (gold) deposits, vibrant agricultural (animal husbandry) and diverse ecosystems that has potential support self-sufficiency of its population. However, the cause to <5-year-old malnutrition and stunting remain to opaque requiring elucidation.
Materials and Methods: A mixed method approach, where both qualitative and quantitative research methods were used to elicit and describe in-depth people’s experiences on determinants of malnutrition and stunting in the Insiza District among the <5-year-olds. Statistical comparisons were performed by one-way analysis of variance (ANOVA), followed by Tukey-Kramer multiple comparison post hoc test using Graph Pad In Stat Software. Both probability and purposive sampling were used to triangulate and corroborate findings deriving meaning to explain the factors associated with wasting/ underweight.
Results: Children with birth weights ±2.4kG were predominant in the study sample (57%) when compared to those who were born with 2.5-3.0 kG or >3.1 kG birth weights [19 fold more]. Two meals per day were taken frequently (57%) a mong adults comparable with birth weight underweight frequencies and feeding habits of infants <5-year-olds (53%), showing food insecurity in Isiza District. Households that lived on < US$1.00/day formed relatively the most prominent majority (73%) when compared to those who lived on US$0.87-1.67/day (23%) or US$1.87-2.50 (2%) or US$2.53-3.33 (2%). Health-related expenses (18.3%), education expenses (25%) and staple food related expenses (56.7%) took the bulk of the income without meaningful effect on child malnutrition. Fathers were over represented as household income usage decision markers in households with malnourished and stunted <5-year-olds (43%) compared to mothers, the family or both parents. Poverty was present in 65% of the households which had malnourished and or stunted children. Malnourishment was from nutritional deficit and non-nutritional lack (25%) while 20% had malnutrition from other determinants other than food consumption score.
Conclusion: More than half (57%) children who developed malnutrition were underweight at birth and born in families with who had two meals a day (57%). Malnutrition was influenced negatively by marital status, household leadership, household income, size, religion, educations status and consumption scores.

Aims: The objective was to compare the sedimentation spontaneous in tube technique (SSTT), the direct smear, the zinc sulfhate (surface film and sediment analyzed) methods with the formalin-ethyl acetate method as the reference standard.
Study Design: This a cross-sectional study performed in two populations around Chapala lake, Jalisco, Mexico.
Place and Duration of Study: Sample Department of Medical Sciences and Life, University Center of the Ciénega, University of Guadalajara, Ocotlán, Jalisco, Mexico.
Department of Physiology, Health Sciences University Center. University of Guadalajara, Jalisco. México, between June 2018 and July 2019.
Methodology: Sample: We included a total of 297 samples and were analyzed by the direct smear, the zinc sulfhate (surface film and sediment analyzed), the SSTT and formalin-ethyl acetate methods.
Results: The SSTT was able to detect 40% of intestinal parasites, very good agreement for Entamoeba complex, Entamoeba coli, and Ascaris lumbricoides kappa index=0.697, 0.791, 0.696, respectively and excellent agreement for Giardia lamblia kappa index = 0.843. Regarding the isolation of Blastocystis spp, only a poor agreement was found among all techniques. The SSTT was able to detect multiple parasites with a sensitivity of 82.90% and specificity 83.80 kappa index= 0.649.
Conclusion: The SSTT showed a very good agreement for the diagnosis intestinal polyparasitism which could represent another alternative for the concentration and identification protozoans and intestinal helminthes in low-resource settings.
Mental Health First Aid Training: A Study of Community Members’ Pre and Post-training Responses to a 17-Item Questionnaire
Authors: Al-Habeeb Abdulhameed Abdullah , Aleshaiwi Haifa Saad , Qureshi Naseem Akhtar 
Published: May 2020

Background: Mental Health First Aid, an important component of metal health educational programs, targets naive community members, public, allied mental health personnel, and mental health experts with specific reference as to how these trained aiders should help people in crisis or with mental health conditions in the community.
Objective: This study aimed to describe pre-to-post-test assessment of those who were trained in MHFA program.
Setting: National Center for Mental Health Promotion, Riyadh, Saudi Arabia.
Methods: Trained mental health professionals organized MHFA courses (n=35) for training self-selected, nonrandomized community members (n=862) who were assessed pre-to-post training by using an adapted 17-item questionnaire for measuring the impact of MHFA course on their mental health knowledge, perception, attitude and practice.
Results: The participants’ responses to questionnaire were varied at pre-and post-test evaluation and 65% of them showed mild to significant positive changes in their responses, and the rest were not affected positively after this course, possibly attributed to multiple factors related to naïve community trainees, advanced questionnaire, short timeline and dissimilar instructors.
Conclusion: Although all participants well received the MHFA courses, 65% of participants’ pre-to-post-test responses improved positively. The preliminary results of this study are not generalizable to the whole community, need to be cautiously interpreted and this research is calling for more studies especially randomized controlled trials in future.

AbstractPurposeTo identify causes of error, and present the concept of an automated technique that improves efficiency and helps to reduce transcription and manual data entry errors in the treatment planning of total body irradiation (TBI).MethodsAnalysis of incidents submitted to incident learning system (ILS) was performed to identify potential avenues for improvement by implementation of automation of the manual treatment planning process for total body irradiation (TBI). Following this analysis, it became obvious that while the individual components of the TBI treatment planning process were well implemented, the manual ‘bridging’ of the components (transcribing data, manual data entry etc.) were leading to high potential for error. A C#‐based plug‐in treatment planning script was developed to remove the manual parts of the treatment planning workflow that were contributing to increased risk.ResultsHere we present an example of the implementation of “Glue” programming, combining treatment planning C# scripts with existing spreadsheet calculation worksheets. Prior to the implementation of automation, 35 incident reports related to the TBI treatment process were submitted to the ILS over a 6‐year period, with an average of 1.4 ± 1.7 reports submitted per quarter. While no incidents reached patients, reports ranged from minor documentation issues to potential for mistreatment if not caught before delivery. Since the implementation of automated treatment planning and documentation, treatment planning time per patient, including documentation, has been reduced; from an average of 45 min pre‐automation to <20 min post‐automation.ConclusionsManual treatment planning techniques may be well validated, but they are time‐intensive and have potential for error. Often the barrier to automating these techniques becomes the time required to “re‐code” existing solutions in unfamiliar computer languages. We present the workflow here as a proof of concept that automation may help to improve clinical efficiency and safety for special procedures.
A Tailorable Family of Elastomeric‐to‐Rigid, 3D Printable, Interbonding Polymer Networks

Published: May 2020

AbstractSoft materials with widely tailorable mechanical properties throughout the material's volume can shape the future of soft robotics and wearable electronics, impacting both consumer and defense sectors. Herein, a platform of 3D printable soft polymer networks with unprecedented tunability of stiffness of nearly three orders of magnitude (MPa to GPa) and an inherent capability to interbond is reported. The materials are based on dynamic covalent polymer networks with variable density of crosslinkers attached to prepolymer backbones via a temperature‐reversible Diels–Alder (DA) reaction. Inherent flexibility of the prepolymer chains and controllable crosslinking density enable 3D printed networks with glass transition temperatures ranging from just a few degrees to several tens of degrees Celsius. Materials with an elastomeric network demonstrate a fast and spontaneous self‐healing behavior at room temperature both in air and under water—a behavior difficult to achieve with other crosslinked materials. Reversible dissociation of DA networks at temperatures exceeding ≈120 °C allows for reprintability, while control of the stereochemistry of DA attachments enables reprogrammable shape memory behavior. The introduced platform addresses current major challenges including control of polymer interbonding, enhanced mechanical performance of printed parts, and reprocessability of 3D‐printed crosslinked materials in the absence of solvent.

AbstractHigh quality opal‐like photonic crystals containing graphene are fabricated using evaporation‐driven self‐assembly of soft polymer colloids. A miniscule amount of pristine graphene within a colloidal crystal lattice results in the formation of colloidal crystals with a strong angle‐dependent structural color and a stop band that can be reversibly shifted across the visible spectrum. The crystals can be mechanically deformed or can reversibly change color as a function of their temperature, hence their sensitive mechanochromic and thermochromic response make them attractive candidates for a wide range of visual sensing applications. In particular, it is shown that the crystals are excellent candidates for visual strain sensors or integrated time‐temperature indicators which act over large temperature windows. Given the versatility of these crystals, this method represents a simple, inexpensive, and scalable approach to produce multifunctional graphene infused synthetic opals and opens up exciting applications for novel solution‐processable nanomaterial based photonics.
