Published: December 2021

Durante el año 2020 la pandemia por COVID-19 irrumpió en las condiciones concretas de existencia y de la cotidianeidad de la población mundial. El mundo entero se enfrentó a un fenómeno sin precedentes e impensado hasta el momento. La educación universitaria se vio obligada a establecer nuevos modos para llevar adelante las clases: los entornos virtuales de aprendizaje.
Específicamente, los espacios curriculares de prácticas profesionales supervisadas tuvieron el desafío de rediseñar las prácticas en terreno –planificadas generalmente desde la presencialidad física– de modos novedosos, diferentes, más allá de lo establecido por las pautas académicas prescriptas en torno a estas actividades.
Integramos un equipo de cátedra que lleva adelante uno de los espacios curriculares de práctica previstos en la Licenciatura de Psicología, de la Facultad de Humanidades, Artes y Ciencias Sociales, Universidad Autónoma de Entre Ríos: la Práctica Profesional Supervisada (PPNS) en Grupo, Organización, Institución y Comunidad.
En este escrito, intentaremos hacer un recorrido por la experiencia de recrear un espacio académico en entornos virtuales de aprendizaje. Asimismo, reflexionaremos sobre la complejidad que ello requirió al momento de pensar una práctica desde lo posible en un escenario de pandemia y aislamiento.

Entrevista a la Dra. María del Carmen Castells
Authors: Luna María Virginia 
Published: December 2021

Compartimos una conversación mantenida con la Dra. María del Carmen Castells a propósito de la publicación de su libro Impresiones sobre educación. Enunciados y saberes en torno a la crisis educativa en libros editados en Argentina en el período 1990-2005 (Prohistoria, 2018). Mariquita, con larga trayectoria en investigación y docencia en la universidad, recupera el proceso de hechura del texto y un conjunto de problematizaciones que tienen hondas implicancias actuales.
Para anticipar algunas referencias sobre la obra, vale decir que en la sucesión de publicaciones contemporáneas sobre educación ese libro sale al cruce mostrándonos algo peculiar: nos permite extrañarnos acerca de qué decimos sobre educación, puesto que analiza cómo estas maneras de decir -que se van asentando en textos o líneas de investigación- tienen trazados insospechados. La investigación que expone realiza cortes históricos que inician en la década de 1980 y se extienden hasta los primeros años del nuevo siglo tomando al «libro» impreso como pieza de análisis. Disecciona y compone una parte muy importante del campo enunciativo de la educación, que es aquel que se tramó en torno a la noción de crisis. Campo que va reconstruyendo desde las incidencias de las políticas editoriales, las políticas públicas y el campo intelectual de la educación. Toma una dirección difícil: la arqueología de Michel Foucault. Pablo Rodríguez (2019) dice que existe un Foucault que sale «de memoria»: el de las «disciplinas». Un «nuevo» Foucault que se descubre justamente bajo un efecto editorial: el de la publicación de los cursos de los años 1970 y 1980 que hace que hoy sea «dicho» desde la atención a la biopolítica y la gubernamentalidad. Entre estos dos, el Foucault arqueólogo parecería perimido. Sin embargo, por fuera de esta comprobación, en esta entrevista la autora destaca el potencial heurístico de la arqueología y nos invita a interrogarnos acerca de qué decimos sobre educación y cuáles han sido las condiciones de posibilidad para hacerlo.

Published: December 2021

The article is dedicated to the the problem of not considering the real meteorological conditions in planning the flight task of the unmanned aerial vehicle (UAV) A1-CM Furia . Unmanned aerial system(UAS) A1-CM Furia has been developed and manufactured by LLC SPC Athlon Avia since 2014. Within 2019-2020, the UAS passed a full spectrum of state tests and was adopted by the Armed Forces of Ukraine. The main criteria that this UAS meets are the detection and tracking of enemy objectives, equipment maintenance and target reconnaissance. Among the peculiarities of UAV application are performance of tasks in adverse meteorological conditions, the use of radio-electronic suppression by the opposing parties, significant spatial characteristics of the areas of responsibility of units and subdivisions for reconnaissance and engagement.
The change in the charge current of the battery depending on the air temperature and the change in the charge current of the battery depending on the wind speed in different meteorological conditions were analyzed in the article.
The article presents experimental results that determine the order of current consumption for battery time depending on meteorological factors, such as wind speed and air temperature. These results indicate that the UAV A1-CM Furia during the task accomplishment can not meet the flight characteristics that are defined in the flight operation manual UAS (FAM). The FAM does not separate the differences in the use of UAV in different meteorological conditions. This causes possible errors in calculating the maximum length of the route and the maximum possible time in the air.
In the article it was proposed to develop a correction for the use of UAV depending on changes in wind speed and temperature .
During the assessing of possible corrections for the use of UAV at different wind speeds and air temperatures, the accuracy of determining the possible values of the maximum route length and maximum time of UAV in the air allows us to calculate more accurate data for future tasks accomplisment.
Experimental methods of calculating corrections took a large part in the specific study of information without taking into account the real meteorological conditions while planning the flight task of the UAV A1-CM Furia.
The obtained results show that without further consideration of meteorological conditions while planning a flight task there may be inaccuracies.

The complex indicator of the reliability of electronic means - the readiness factor - significantly depends on the average recovery time. At the same time, the largest labor costs are spent by repair specialists on finding a faulty element. Diagnostic repair support depends on the models used in the development of defect detection algorithms. The most common use of diagnostic models in the form of a graph of information and energy connections, which consists of three types of structures: sequential connection of elements, converging and diverging. The latter did not receive the necessary research.
In the article as a result of research of influence of forms of the graph of information and power communications on indicators of quality of diagnostic maintenance of subsystems of power supply of radio electronic means analytical dependences of quantitative estimation of the controlled variables on average recovery time are received for the first time. This allows to improve the quality of diagnostic support of existing and promising samples during their design. Minimization of diagnostic errors makes it possible to verify the feasibility of using diagnostic and metrological support during the current repair of electronic devices by the aggregate method, which reduces the recovery time, especially in the field.
Depending on the volume of initial data, possible methods for quantifying the probability of the preferred choice of branches of power subsystems of radio electronic means, which also reduces the average recovery time by checking primarily the least reliable and do not require much time to perform checks and troubleshooting.
The obtained results should be used in improving the diagnostic and metrological support of power supply subsystems of existing electronic devices and its development for promising samples in order to improve the quality of maintenance, regardless of the structure of choice.
Dietary Macronutrients Do Not Differently Influence Postprandial Serum and Plasma Brain-Derived Neurotrophic Factor Concentrations: A Randomized, Double-Blind, Controlled Cross-Over Trial
Authors: Gravesteijn Elske , Mensink Ronald P. , Smeets Ellen T. H. C. , Plat Jogchum 
Published: December 2021

Objectives: Brain-derived neurotrophic factor (BDNF) plays a role in cognition and metabolism. Specific nutrients can affect fasting BDNF concentrations, which are potentially mediated by insulin and/or glucose. Since macronutrients trigger each a different insulin and glucose response, we examined postprandial effects of meals rich in fat, carbohydrates, or protein on BDNF concentrations. BDNF was analyzed in serum and plasma, since concentration differences can be found between matrices.Methods: Healthy overweight/obese male participants (n = 18) participated in this randomized, double-blind, cross-over trial consisting of three test days with 1 week wash-out periods. Either a high-fat (En% fat, carbohydrates, protein: 52.3, 39.2, 8.0), high-carbohydrate (En% 9.6, 81.5, 8.6) or high-protein meal (En% 10.6, 51.5, 36.9) was consumed on each test day. BDNF concentrations were measured after 0, 60, and 240 min. Glucose and insulin concentrations were measured after 0, 15, 30, 45, 60, 90, 120, and 240 min.Results: BDNF concentrations were higher in serum compared with plasma (P &lt; 0.001). Postprandial BDNF concentrations in serum decreased significantly after the high-fat (P = 0.013) and high-carbohydrate meals (P = 0.040), and showed a trend after the high-protein meal (P = 0.076). No differences were found between meals (P = 0.66). Postprandial BDNF concentrations measured in plasma did not significantly change after the different meals (P = 0.47). As total area under the curve (AUC) for glucose was significantly higher after the high-carbohydrate meal compared with the high-fat (P = 0.003) and high-protein meals (P &lt; 0.001), and the total AUC for insulin was higher after the high-carbohydrate (P &lt; 0.001) and high-protein meals (P &lt; 0.001) compared with the high-fat meal, it seems that acute changes in glucose and insulin do not affect postprandial BDNF concentrations. However, after the high-protein meal, the higher total AUC for glucose correlated with lower serum BDNF concentrations, and a higher maximal increase in glucose correlated with a lower maximal increase in plasma BDNF concentrations. There were no correlations with insulin concentrations after either meal.Conclusion: Serum BDNF concentrations were higher than plasma concentrations. Since postprandial BDNF responses were not different between the meals, we conclude that there is no role for insulin or glucose in regulating postprandial BDNF concentrations.Clinical Trial Registration: [www.ClinicalTrials.gov], identifier [NCT03139890].
The Relationships Amongst Pediatric Nurses' Work Environments, Work Attitudes, and Experiences of Burnout
Authors: Buckley Laura , Berta Whitney , Cleverley Kristin , Widger Kimberley 
Published: December 2021

Background: Pediatric nurses care for some of the most vulnerable patients in our healthcare system. Research on health care provider organizational behavior shows that the quality of care nurses provide is directly related to their well-being, influenced by Burnout and job stress, in the workplace. However, most of the research conducted on nursing populations neglects to separately study nurses who care for children. In a resource limited system where health care provider well-being is recognized as a priority, it is important for administrators to understand the environmental and attitudinal work factors most influential to pediatric nurse work outcomes in order to target optimization strategies. The aim of the study was to identify which modifiable work environment factors, e.g., [Incivility, Perceived Organizational Support, Quality of Work-life] make the greatest contribution to the work outcome of Burnout (i.e., Personal Accomplishment, Emotional Exhaustion, Depersonalization) in pediatric nurses.Methods: A cross-sectional survey design was used at a large quaternary care pediatric hospital in Toronto, Canada. We administered a survey to a convenience sample of all registered nurses with &gt;3 months experience in the Pediatric, Cardiac, and Neonatal Intensive Care Units from January 2021–March 2021. Path analysis was used to test our proposed model which was specified a priori based on a review of the literature.Results: 143 nurses completed the survey. Path analysis of the tested model resulted in good fit. Quality of Work-life had the largest direct effect on Work Engagement (β = 0.582, S.E. = 0.111, p &lt; 0.001). Work Engagement had the largest direct effect on Personal Accomplishment (β = 0.68, S.E. = 0.53, p &lt; 0.001). Quality of Work-life had the largest indirect effect on Personal Accomplishment (β = 0.4, S.E. = 0.65, p &lt; 0.001), Emotional Exhaustion (β = −0.33, S.E. = 0.87, p &lt; 0.001), and Depersonalization (β =−0.17, S.E. = 0.41, p = 0.006), respectively. Work Engagement had the largest total effect on Personal Accomplishment (β = 0.68, S.E. = 0.64, p &lt; 0.001) and the third largest total effect on Emotional Exhaustion (β = −0.57, S.E. = 0.83, p &lt; 0.001). Quality of Work-life had the second largest total effect on Work Engagement (β = 0.58, S.E. = 0.11, p &lt; 0.001) indicating that Quality of Work-life is mediated through Work Engagement for its effect on Burnout.Conclusions: Our results indicate work environment and work attitude factors that can provide organizational leadership with a targeted focus to reduce pediatric critical care nurse Burnout, and thus improve provider well-being, in a resource limited system.

Published: December 2021

Background/Aim: The turbo spin-echo (TSE) sequence is widely used for musculoskeletal (MSK) imaging; however, its acquisition speed is limited and can be easily affected by motion artifacts. We aimed to evaluate whether the use of a simultaneous multi-slice TSE (SMS-TSE) sequence can accelerate MSK imaging while maintaining image quality when compared with the routine TSE sequence.Methods: We prospectively enrolled 71 patients [mean age, 37.43 ± 12.56 (range, 20–67) years], including 37 men and 34 women, to undergo TSE and SMS sequences. The total scanning times for the wrist, ankle and knee joint with routine sequence were 14.92, 13.97, and 13.48 min, respectively. For the SMS-TSE sequence, they were 7.52, 7.20, and 6.87 min. Quantitative parameters, including the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR), were measured. Three experienced MSK imaging radiologists qualitatively evaluated the image quality of bone texture, cartilage, tendons, ligament, meniscus, and artifact using a 5-point evaluation system, and the diagnostic performance of the SMS-TSE sequences was evaluated.Results: Compared with the routine TSE sequences, the scanning time was lower by 49.60, 48.46, and 49.04% using SMS-TSE sequences for the wrist, ankle, and knee joints, respectively. For the SNR comparison, the SMS-TSE sequences were significantly higher than the routine TSE sequence for wrist (except for Axial-T2WI-FS), ankle, and knee joint MR imaging (all p &lt; 0.05), but no statistical significance was obtained for the CNR measurement (all p &gt; 0.05, except for Sag-PDWI-FS in ankle joint). For the wrist joint, the diagnostic sensitivity, specificity, and accuracy were 88.24, 100, and 92%. For the ankle joint, they were 100, 75, and 93.33%. For the knee joint, they were 87.50, 85.71, and 87.10%.Conclusion: The use of the SMS-TSE sequence in the wrist, ankle, and knee joints can significantly reduce the scanning time and show similar image quality when compared with the routine TSE sequence.
Surgical Outcomes of Transperitoneal Para-Aortic Lymphadenectomy Compared With Extraperitoneal Approach in Gynecologic Cancers: A Systematic Review and Meta-Analysis
Authors: Li Kun-peng , Deng Xian-zhong , Wu Tao 
Published: December 2021

Purpose: The optimal surgical approach for para-aortic lymphadenectomy (PALND) in gynecologic cancers using minimally invasive surgery (laparoscopy or robotic-assisted) is controversial. This study summarizes the current evidence on the extraperitoneal (EP) approach and compares its perioperative, surgical outcomes, and complications to the transperitoneal (TP) approach in an updated meta-analysis.Methods: We performed a systematic search in PubMed, Embase, Web of Science, Cochrane Library database for randomized controlled trials (RCTs) and non-RCTs that compare EP to TP for PALND. The main outcomes included surgical, perioperative outcomes, and complications. The weighted mean difference (WMD) and odds ratio (OR) were applied for the comparison of continuous and dichotomous variables with 95% CIs. Three RCTs and 10 non-RCTs trials, including 2,354 patients were identified and enrolled in the meta-analysis.Results: A total of three RCTs and ten non-RCTs trials, including 2,354 patients were identified and enrolled in the meta-analysis. We reported similar results for EP and TP in terms of the hospital stay, estimated blood loss, blood transfusion, conversion to laparotomy, total operative time, and postoperative complications (Clavien grade ≥ 1 and Clavien grade ≥ 3). However, the PALND operative time (WMD −10.46 min, 95% CI −19.04, −1.88; p = 0.02) and intraoperative complications (OR 0.40, 95% CI 0.23, 0.69; p = 0.001) were less with EP. Also, more nodes were removed in EP compared with the TP (WMD 1.45, 95% CI 0.05, 2.86; p = 0.04).Conclusions: The EP approach did not show differences regarding surgical and perioperative parameters compared with the TP approach. However, the number of aortic nodes retrieved was higher. Furthermore, The PALND operative time and intraoperative complications were less in EP.

La sociedad corporativa y la vigencia de la monarquía pactista. De la Baja Edad Media a la emancipación americana
Authors: Carzolio María Inés 
Published: December 2021

Actualmente se continúa insistiendo con que la génesis de las ideas de los proyectos emancipatorios americanos tiene sus raíces en la Ilustración europea, pero desde mediados del siglo XX ciertos autores franceses e hispanoamericanos han explorado fuentes teológicas y filosóficas de la segunda escolástica española, afirmando que el origen del poder real está en Dios, quien inviste de él al pueblo, quien lo transfiere libremente al rey por un pacto de cesión (traslación) bajo ciertas condiciones. Esa concepción del pacto permitió una reacción y respuesta unánime de los americanos ante la crisis de 1808. He aquí el interés del origen y gestación del pactismo hispánico que proporcionó una tradición común.
Sin embargo, el lapso que separa tal origen de la emancipación americana y las vicisitudes que atraviesa España, atenúan la visibilidad de tal conexión. Desde la Baja Edad Media comienzan a desarrollarse las conceptualizaciones jurídico-políticas propias de la organización social antiguoregimental, basadas primordialmente en la idea antropomórfica de cuerpo donde el poder se fragmentaba a diversos niveles e instancias en relación con sus partes, exigiendo que el sistema social resultante fuese descentralizado pero recorrido por relaciones de sujeción entre el rey y sus vasallos. Los reinos peninsulares mostraban variantes de este contractualismo en las Cortes, en cuya documentación pueden hallarse invocaciones del pacto. La llegada del autoritarismo Borbón alteraría la conformación filosófica y jurídica del poder real, puesto que redujeron toda alusión a un pacto originario.
