Investigación educativa: problemática y carácter multidisciplinario. Reflexiones teóricas y filosóficas
Authors: Valle Ana María 
Published: February 2021

El texto es el resultado de una reflexión cuyo principal objetivo es indagar en torno a la investigación educativa y su carácter multidisciplinario. En un primer momento, se asume que, por un lado, la problemática de la investigación educativa está relacionada con el sentido conceptual y teórico- metodológico que nace del pensamiento y de la crítica a las preguntas por la educación. Por otra parte, el prefijo multi- no solo hace referencia a la abundancia y a la diversidad; también alude a las intersecciones, desvíos, irrupciones y articulaciones de las disciplinas. En un segundo momento, se revisa la investigación educativa desde la disciplinarización del saber como un combate entre saberes muy propio de la modernidad. El planteamiento teórico metodológico que se sigue es la hermenéutica. Se considera que toda interpretación tiene que protegerse contra la arbitrariedad de las ocurrencias y, más bien, debe orientar su mirada a la “cosa misma”. En este caso, esta mirada interpretativa se dirige a la comprensión de la problemática de la investigación educativa y su carácter multidisciplinario.
Managing Nontechnical Risk in Offshore Projects
Authors: Whitfield Stephen 
Published: February 2021

In recent years, offshore projects have increased in size, scope, and cost, expanding into deeper waters and new frontiers. Alongside this growth, the negative potential for nontechnical issues relating to health, safety, security, environment, and social responsibility (HSSE-SR) on a project’s timeline has also increased. Projects are under more intense scrutiny from the companies that own and operate them.
In an effort to better understand the value of nontechnical risk (NTR) at the project and portfolio level, companies are searching for the proper systems and processes to deliver quality HSSE-SR performance. The elements of NTR assessment, the methodologies of managing NTR, and how they relate to offshore projects will be examined.

Abstract
Purpose To evaluate the diagnostic accuracy of SPECT/CT arthrography in patients with suspected aseptic prosthesis loosening following hip and knee arthroplasty. Methods A retrospective review of 63 SPECT/CT arthrogram studies (36 knees and 27 hips) between February 1, 2013 and July 1, 2018 was conducted. All patients underwent clinical and radiologic evaluation as part of their assessment for persistent pain following hip and knee arthroplasty. The detection of tracer activity along the bone-prosthetic interface on SPECT/CT suggests aseptic loosening. Operative assessment as well as clinical/ radiologic follow-up at a minimum of one year were used as the reference standard. Results The sensitivity and specificity of SPECT/CT for detection of aseptic loosening was 6/7 (86%) and 55/56 (98%) respectively. This gives a positive predictive value (PPV) of 6/7 (86%), a negative predictive value (NPV) of 55/56 (98%), and a diagnostic accuracy of 61/63 (97%). Conclusion SPECT/CT arthrography has a high diagnostic accuracy (97%) in the evaluation of loosening of both hip and knee arthroplasties in patients with persistent post-procedural pain.

Abstract
BackgroundCommunities affected by infectious disease outbreaks are increasingly recognised as partners with a significant role to play during public health emergencies. This paper reports on a qualitative case study of the interactions between affected communities and public health institutions prior to, during, and after two emerging tick-borne disease events in 2016: Crimean-Congo Haemorrhagic Fever in Spain, and Tick-Borne Encephalitis in the Netherlands. The aim of the paper is to identify pre-existing and emergent synergies between communities and authorities, and to highlight areas where synergies could be facilitated and enhanced in future outbreaks.MethodsDocumentary material provided background for a set of semi-structured interviews with experts working in both health and relevant non-health official institutions (13 and 21 individuals respectively in Spain and the Netherlands), and focus group discussions with representatives of affected communities (15 and 10 individuals respectively). Data from all sources were combined and analysed thematically, initially independently for each country and then for both countries together.ResultsStrong synergies were identified in tick surveillance activities in both countries, and the value of pre-existing networks of interest groups for preparedness and response activities was recognised. However, authorities also noted that there were hard-to-reach and potentially vulnerable groups, such as hikers, foreign tourists, and volunteers working in green areas. While the general population received preventive information about the two events, risk communication or other community engagement efforts were not seen as necessary specifically for these sub-groups. Post-event evaluations of community engagement activities during the two events were limited, so lessons learned were not well documented.ConclusionsA set of good practices emerged from this study, that could be applied in these and other settings. They included the potential value of conducting stakeholder analyses of community actors with a stake in tick-borne or other zoonotic diseases; of utilising pre-existing stakeholder networks for information dissemination; and of monitoring community perceptions of any public health incident, including through social media. Efforts in the two countries to build on the community engagement activities that are already in place could contribute to better preparedness planning and more efficient and timely responses in future outbreaks.
Research on Improved DS&nbsp;Evidence Theory
Authors: Lin Zhen , Xie Jinye 
Published: February 2021

Abstract
In view of the lack of effective information fusion model for heterogeneous multi-sensor, an improved DS evidence theory algorithm is designed to fuse heterogeneous multi-sensor information. The algorithm first introduces the compatibility coefficient to characterize the compatibility between the evidence, obtains the weight matrix of each proposition, and then redistributes the BPA of each focal element to obtain a new evidence source. Then, the concept of credibility is introduced, and the synthetic rules are improved by using the credibility of evidence and the average support of evidence focal elements, so as to obtain the fusion results. The results show that compared with other algorithms, this algorithm can solve the problems of DS evidence theory in dealing with highly conflicting evidence to a certain extent, and the fused results are more reasonable and converge faster.

Abstract
Background: Causes of non-alcoholic fatty liver disease and its progression include visceral fat accumulation and loss of muscle mass; however, which is more critical is unclear. To clarify this, we examined the relationship between body composition and non-alcoholic fatty liver disease progression as indicated by fibrosis and the non-alcoholic fatty liver disease activity score.Methods: This cross-sectional study comprised 139 patients (54 men; age, 20–76 years) treated for non-alcoholic fatty liver disease between December 2010 and January 2020. Body composition measurements, histological examinations of liver samples, and comprehensive blood chemistry tests were performed. The relationship between body composition and non-alcoholic fatty liver disease histology findings was analyzed using the logistic regression model.Results: Fibrosis was significantly and inversely correlated with muscle mass and appendicular skeletal muscle mass and significantly and positively correlated with fat mass, fat mass/height squared, visceral fat area, and waist-hip ratio (P <0.05). After adjustment for sex, blood chemistry measurements, and body composition indices, fibrosis remained associated with appendicular skeletal muscle mass, fat mass, fat mass/height squared, and visceral fat area (P <0.05). Non-alcoholic fatty liver disease activity score ≥5 significantly correlated with fat mass and fat mass/height squared in a univariate but not multivariate analysis.Conclusions: Fibrosis in non-alcoholic fatty liver disease, an indicator of unfavorable long-term outcomes, is associated with more indices of fat mass than of those of muscle mass. Hence, fat mass should be controlled to prevent non-alcoholic fatty liver disease progression.

Abstract
The hydraulic support group and the surrounding rock in fully mechanized mining faces often do not exist in isolation; rather, they compose in a mutually coupled system. Research on the mechanical characteristics of roofs under the support of group supports can lay a foundation for the determination of the ideal support strength of group support equipment. This paper establishes a coupled mechanical model of the surrounding rock of hydraulic support groups in a fully mechanized mining face. Through variable parameter calculations, the influence of different roof elastic moduli, mining heights, working face lengths, end face distances, support stiffnesses, coal wall stiffnesses and direct roof thicknesses on roof deformation is analyzed, and the corresponding ideal support strength of a hydraulic support is given. The results show that: the deformation of the roof and the ideal support strength of the hydraulic support group decrease as the elastic modulus of the roof increase; the deformation amount of the roof and the ideal support strength of the hydraulic support group increase as the mining height increases; the deformation amount of the roof and the ideal support strength of the hydraulic support group increase as the working face length increases; the deformation amount of the roof and the hydraulic support group also increase. The results also show that the ideal support strength of the support group decreases as the face distance of the top beam end increases; the deformation of the roof decreases significantly as the equivalent stiffness of the hydraulic support group increases, but the ideal support strength of the hydraulic support group increases significantly; the deformation amount of the roof and the ideal support strength of the hydraulic support group decrease significantly as the equivalent stiffness of the coal wall increases; and the deformation amount of the roof and the hydraulic support are significantly reduced. The ideal support strength of the support group decreases as the thickness of the direct roof increases, especially in the middle of the working face. Finally, by setting the ideal support strength in the 12401 working face of the Shangwan Coal Mine of Shendong Group, the accuracy of the calculation results is verified by the multisensor measurement method. The research results provide theoretical support for the development of coal resources for deep mining and intelligent directions on Earth.

Abstract
Background: It remains no clear conclusion about which is better between robot-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS) for the treatment of patients with non-small cell lung cancer (NSCLC). Therefore, this meta-analysis aimed to compare the short-term and long-term efficacy between RATS and VATS for NSCLC.Methods: Pubmed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Medline and Web of Science databases were comprehensively searched for studies published before December 2020. The quality of the articles was evaluated using the Newcastle-Ottawa Scale (NOS) and the data analyzed using the Review Manager 5.3 software. Fixed or random effect models were applied according to heterogeneity. A sensitivity analysis was conducted. A funnel plot of the overall complication was used to assess the potential publication bias. Results: A total of 18 studies including 11247 patients were included in the meta-analyses, of which 5114 patients were in the RATS group and 6133 in the VATS group. Compared with VATS, RATS was associated with less blood loss (WMD = -50.40, 95% CI -90.32~-10.48, P = 0.010), lower conversion rate (OR = 0.50, 95% CI 0.43~0.60, P < 0.001), more harvested lymph nodes (WMD = 1.72, 95% CI 0.63~2.81, P = 0.002) and stations (WMD = 0.51, 95% CI 0.15~0.86, P = 0.005), shorter duration of postoperative chest tube drainage (WMD = -0.61, 95% CI -0.78~-0.44, P < 0.001) and hospital stay (WMD = -1.12, 95% CI -1.58~-0.66, P < 0.001), lower overall complication rate (OR = 0.90, 95% CI 0.83~0.99, P = 0.020), and lower recurrence rate (OR = 0.51, 95% CI 0.36~0.72, P < 0.001). There was no significant difference between RATS and VATS in operative time, mortality, overall survival (OS), and disease-free survival (DFS). Sensitivity analysis showed that no significant differences were found between the two techniques in conversion rate, number of harvested lymph nodes and stations, and overall complication. Conclusions: The results revealed that RATS is a feasible and safe technique compared with VATS in terms of short and long term outcomes. Moreover, more randomized controlled trials comparing the two techniques with rigorous study designs are still essential to evaluate the value of the robotic surgery for NSCLC.

Abstract
Background

Since its molecular isolation on January 7, 2020, the novel coronavirus SARS-CoV-2 has spread rapidly, taking governments worldwide off-guard. The virus arrived in low and middle-income countries violently, especially in Latin America. Ecuador received the worst outbreak in the world if we count excess mortality per capita. Although one study has reported the epidemiological impact of COVID-19 in Ecuador, there is no clinical course or outcome data among intensive care patients with COVID-19 in Ecuador. This study describes the clinical, epidemiological, and therapeutical features of 89 patients hospitalized in a secondary-level hospital in Quito, Ecuador.
Methods

We did a retrospective cohort study. We collected health records data from adult patients with severe COVID-19 admitted to the intensive care unit (ICU) in Quito, Ecuador, during the first five months of the SARS-CoV-2 outbreak in Ecuador. All patients had a confirmed SARS-CoV-2 RNA infection diagnostic, a positive real-time RT-PCR, and pulmonary imaging suggesting COVID-19. We used the Chi-square test or a Fisher's exact statistic to analyze risk and associations between survivors and non-survivors due to COVID-19. We used the ROC curve analysis to predict mortality, determining cut-off points for the parameters related to mechanical, analytical, and cytometry ventilation. At the multivariate level, we used the Wald test to evaluate model categorical predictors during the regression analysis.
Results

89 patients with COVID-19 were recruited during the study. The average age of the patients was 54.72 years. Man represented 68.54% (n = 61) and women 31,46% (n = 28). Significant differences were observed in terms of mortality (men 40.98% vs. women 17.76%). Serological parameters demonstrated that LDH and IL-6 at 24 hours were higher among non-survivors when compared with survivors. Persistent hypercapnia ( > > 45 mmHg), a PaFiO2 ratio of less than 140 mmHg, and a positive end-expiratory pressure (PEEP) titration greater than nine mmHg were also associated with higher mortality.
Conclusions

Increased levels of LDH at 24 hours, IL-6, the lymphocyte and platelet count at 48 hours, the neutrophil count at 48 hours, and the INL are factors associated with higher motility, increased risk of failed extubation and reintubation

Abstract
BackgroundEye injury is a serious public health problem being in the world, that causes unilateral blindness, a particular condition in children due to the functional impact and psychosocial implications. The eye injury can be prevented thanks to the identification of risk factors associated with the socio-cultural context, this aspect has motivated studies in the pediatric population in United States, India, Australia, Cuba, Egypt, United Kingdom, Brazil, Colombia, Marathwada and Canada, among others. So the objetive of the present study is to describe the sociodemographic and epidemiological characteristics of pediatric eye injury and its effects on ocular structures in a tertiary public hospital from Colombia.MethodA retrospective cross-sectional study was carried out between January 1, 2015, and December 31, 2017, in a tertiary public hospital of a medium-sized city located in the Northeast of Colombia. Children under 15 years old with trauma to the eyeball or its adnexa were included. The Birmingham Eye Trauma Terminology System (BETTS) was used. Eye burns and Ocular adnexa were also included.Results61 cases of eye injuries were recorded, 67.21% (41 cases) of which were males. 57.37%(35 of the cases) corresponded to closed-globe injuries both contusion and lamellar laceration. Visual acuity fluctuated between 20/20 and 20/40. 14.75% (9 cases) were Open-globe injuries while 50% (4 cases) were penetrating trauma. 27.86% of the injuries (17 cases) did not directly compromise the eyeball, 58.82% (10 of these cases) of which corresponded to eyelid wounds, and neither of those had the visual acuity informationConclusionThe study showed that the majority of eye traumas are closed globe, caused by

Abstract
Background

Universities should be sensitive to the needs and expectations of students. This study aimed to analyze the gap between perceptions and expectations of students of Jiroft University of Medical Sciences about the quality of educational services.
Methods

This descriptive-analytical study was conducted on 213 medical, nursing, and midwifery students. Census method was used to sampling. The data were collected using a multi-dimensional questionnaire (SERVQUAL-22 items). Finally, the data were analyzed by T-test, ANOVA, and correlation coefficient. the significance level was considered as 0.05.
Results

The mean age of the participants in this study was 21.62 ± 1.79. Of students 132 (62%) were female and 186 (87.3%) were single. There was a quality gap in all dimensions of the quality of educational services (empathy, reliability, responsiveness, assurance, and tangibility). The highest quality gap was observed in the empathy dimension − 8.66 (4.2) and the smallest gap was observed in the tangibility dimension − 4.18 (4.4). Average score of educational services gap in reliability dimension in terms of education of mothers (p = 0.01), and average score of educational services gap in reliability dimension (p = 0.009), tangibility dimension (p = 0.015) and overall score (p = 0.039) in terms of their fathers’ education were significant.
Conclusions

The results indicate that the expectations of the students in all aspects of the quality of educational services (empathy, reliability, responsiveness, assurance, and tangibility) are more than their perceptions. Thus, the authorities must take the necessary measures to meet the expectations of students.

Abstract
Sepsis-induced cardiomyopathy (SIC) is a major contributing factor for morbidity and mortality in sepsis, but the underlying mechanisms are poorly understood. Previous work has suggested that mitochondrial oxidative phosphorylation is altered in mice with SIC, but the molecular mechanisms remain unidentified. Here, we performed a proteomic analysis of cardiac mitochondria isolated from sham and SIC mice. Of the 665 mitochondrial and metabolically coupled proteins identified in the proteomics assay, 36 were significantly altered in septic mice. The mitochondrial remodeling involved various energy metabolism pathways including subunits of the electron transport chain (ETC), fatty acid catabolism enzyme, and carbohydrate oxidative metabolism. We also identified a significant increase of pyruvate dehydrogenase (PDH) kinase 4 (PDK4) and inhibition of PDH activity in septic hearts. Furthermore, oxygen consumption by mitochondria from septic hearts was reduced when pyruvate was provided as a substrate but was unchanged in the presence of the Complex II substrate succinate, or the beta-oxidation substrate palmitoylcarnitine, both of which do not require PDH. Our data suggest that PDK4-mediated PDH inactivation and ETC molecular remodeling may contribute to the reduced mitochondrial oxidative metabolism during SIC and provide a molecular framework for future work.
