Authors: Zhuang Weiqing , Wang Morgan C. , Nakamoto Ichiro , Jiang Ming
Published: March 2021

Big data analytics (BDA) in e-commerce, which is an emerging field that started in 2006, deeply affects the development of global e-commerce, especially its layout and performance in the U.S. and China. This paper seeks to examine the relative influence of theoretical research of BDA in e-commerce to explain the differences between the U.S. and China by adopting a statistical analysis method on the basis of samples collected from two main literature databases, Web of Science and CNKI, aimed at the U.S. and China. The results of this study help clarify doubts regarding the development of China’s e-commerce, which exceeds that of the U.S. today, in view of the theoretical comparison of BDA in e-commerce between them.

Published: March 2021

En los últimos años, se ha incrementado el porcentaje de colocación de implantes dentales y, con ello, también la mayor presencia de eventos adversos, por lo que las complicaciones no son infrecuentes. La gran mayoría de recomendaciones para la reducción de complicaciones asociadas con la colocación de implantes dentales están analizadas desde el punto de vista de sus causas directas, juzgando la técnica o al individuo, pero no al sistema en conjunto, cuando este constituye la etiología real de las complicaciones. Recientemente, se ha empezado a considerar más importante la inclusión de los factores humanos y la conciencia de la situación en la comprensión de las complicaciones en implantología oral. Esto ha permitido analizar de manera global tanto al individuo como a su entorno, y aportar soluciones basadas en la prevención. Sin embargo, el conocimiento y la utilización de estos aspectos en implantología oral están aún en vías de popularización, por lo que el objetivo del presente artículo es difundir el enfoque de los factores humanos y la conciencia de la situación en la prevención de complicaciones y en la reducción de riesgos en los procedimientos de colocación de implantes dentales.

Published: March 2021

Sampling for needle nematodes was carried out in a grapevine area in Thessaloniki, North Greece and two nematode species of Longidorus (L. pauli and L. pisi) were collected. Nematodes were extracted from 500 cm3 of soil by modified sieving and decanting method, processed to glycerol and mounted on permanent slides, and subsequently identified morphologically and molecularly. Nematode DNA was extracted from single individuals and PCR assays were conducted to amplify D2-D3 expansion segments of 28S rRNA, ITS1 rRNA, and partial mitochondrial coxI regions. Morphology and morphometry data obtained from these populations were consistent with L. pauli and L. pisi identifications. To our knowledge, this is the first report of L. pauli for Greece, and the second world report after the original description from Idleb, Syria, extending the geographical distribution of this species in the Mediterranean Basin.
Hydration behaviour of limestone-calcined clay and limestone-slag blends in ternary cement
Authors: Parashar Anuj , Bishnoi Shashank
Published: March 2021

The effect of kaolinitic calcined clay and slag on the hydration of limestone-containing ternary blended cements was investigated. The effect of alumina from different sources of SCMs was considered to activate the formation of carboaluminates. Ternary blends with 50% ordinary portland cement clinker, 45% blends of limestone calcined clay (LC2) in 1:2 blend and slag limestone blend (SLS) in 2:1 mix proportion with 5% of gypsum were studied. The hydration behaviour was analysed based on cement mortar compressive strength, heat of hydration using an isothermal calorimeter and bound water measured using thermal gravimetric analysis (TGA). In addition, the degree of hydration of clinker phases and the composition of calcium - alumino - silicate - hydrate (C-A-S-H) gels forming in two different systems were compared on 90 days hydrated samples analysed using X-Ray diffractometry (XRD) and scanning electron microscopy - energy dispersive X-ray spectroscopy (SEM-EDX) respectively. The results show a rapid early strength development in limestone calcined clay cement blend (LC3) but a lower clinker hydration in comparison with slag limestone cement blend (SLSC) at later ages. In both the cement blends the formation of hemicarboaluminate (Hc) and monocarboaluminate (Mc) was confirmed at 90 days, but the conversion of Hc to Mc was higher in SLSC. Results further confirmed a lower degree of hydration and higher alumina incorporation in the C-A-S-H gel in the LC3 comparison to SLSC. The presence of calcium hydroxide was also confirmed in the SLSC blend due to the hydraulic nature of slag that supported the later age conversion of Hc to Mc as not seen in LC3.

Published: March 2021

Gmelina arborea es una especie de rápido crecimiento y fácil adaptación a diversidad de condiciones de sitio; el objetivo del estudio fue analizar las características edáficas y topográficas asociadas con el crecimiento en volumen fustal de G. arborea establecida en el Estado de México y desarrollar un modelo para estimar el volumen fustal. La investigación fue desarrollada en ocho parcelas permanentes de muestreo de forma circular (400 m2), donde se extrajeron 5 sub-muestras de suelo de cada parcela, las cuales fueron mezcladas para formar una muestra final de 500 gramos. El análisis de las características edáficas se hizo con base en la NOM-021-RECNAT-2000 y datos de altitud, pendiente y profundidad. Para el análisis de varianza y prueba de medias, se efectúo un análisis de componentes principales y posteriormente, una regresión lineal múltiple; a través del coeficiente de correlación, se compararon las correlaciones existentes entre las variables elegidas con el paquete estadístico R®. El modelo resultante tomó como variables predictoras la conductividad hidráulica, los nitratos y la relación Ca/Mg; este modelo explicó 71.6% de la variabilidad observada en el volumen fustal (R2ajustado= 0.716). De acuerdo con el resultado de varianza, estas variables no mostraron diferencias significativas. Se concluye que la variación de las características edáficas y topográficas influye en el crecimiento del volumen fustal. Es indispensable conocer la autoecología de la especie, la cual está asociada a condiciones climáticas y edafológicas, así como a la distribución altitudinal.
Estudios de conectividad del paisaje en América Latina: retos de investigación
Authors: Leija Edgar G. , Mendoza Manuel E.
Published: March 2021

Los estudios enfocados a la conectividad del paisaje son actualmente claves para la planificación de la conservación de los ecosistemas; sin embargo, sólo un número limitado de estudios proporcionan datos empíricos sobre los beneficios de la conectividad en la conservación de los ecosistemas terrestres. En este estudio, se analizaron las publicaciones sobre estudios de conectividad particularmente para cuatro tópicos en América Latina de 2000 a 2018, para brindar una visión del estado actual, retos y avances del conocimiento. La búsqueda se realizó en diferentes bases de datos, las cuales se seleccionaron 217 trabajos. Todas las referencias seleccionadas fueron revisadas y clasificadas considerando: a) año de publicación, b) tipo de investigación, c) país de América Latina donde se realizó, d) área de estudio, e) tipo de ecosistema y f) objetivos de la investigación. Los resultados muestran que la mayor parte de los estudios de conectividad se realizan considerando los tópicos: a) de planificación para la restauración, b) modelado y planificación de la cobertura vegetal/uso del suelo y c) servicios ecosistémicos. Sin embargo, los trabajos publicados sobre conectividad y cambio climático han sido escasos. También fue posible identificar publicaciones que abordaron dos tópicos simultáneamente: a) estudios de modelado y planificación de la cobertura vegetal/uso del suelo con estudios de la planificación para la restauración, b) estudios en servicios ecosistémicos con cambio climático, and c) planificación para la restauración con cambio climático. Sin embargo, existe la necesidad de incrementar sustancialmente las investigaciones en los temas de conectividad en América latina.
Cambio de cobertura y uso de suelo en llanura costera asociados a procesos antropogénicos: caso San Blas, Nayarit
Authors: Nájera González Areli , Carrillo González Fátima Maciel , Morales Hernández Julio César , Nájera González Oyolsi
Published: March 2021

Los cambios de uso de suelo generados por el desarrollo de actividades humanas han acelerado la pérdida de cobertura vegetal. Por su ubicación en las llanuras costeras, la cobertura de manglar ha sido una de las más afectadas en los últimos años. Los principales cambios se han evidenciado por actividad acuícola, agropecuaria y turismo. La pérdida de manglar trae como consecuencia modificaciones del clima a escala local, lo que repercute en variaciones del ciclo hídrico y balance salino de las lagunas costeras, propiciando un efecto dominó sobre la biodiversidad, los suelos y por ende las actividades económicas. El presente trabajo tuvo como objetivo evaluar el cambio de cobertura y uso de suelo de la llanura costera de San Blas, Nayarit, del periodo 2000-2019 y su tendencia para el 2038. El método empleado fue la clasificación supervisada de imágenes satelitales en un sistema de información geográfica y la herramienta cadenas de Markov para la proyección futura. Se encontró aumento de áreas de camaronicultura de 4.3%, lo que llevó al desplazamiento de zonas inundables, posiblemente asociado a impactos en el sistema hídrico, provocando una reducción de la cobertura manglar de 4.7%, sin embargo, se prevé que la tendencia continuará en menor magnitud para el 2038. Se espera que esta conclusión sea referente para las decisiones futuras sobre el desarrollo de actividades antropogénicas en esta área y otras de llanura costera.

Published: March 2021

Objective. Evaluate the effects of supplementation with different protein sources (soybean meal and wheat bran with urea) on the productive performance, intake, digestibility, microbial protein synthesis, and metabolic profile of grazing beef heifers. Materials and methods. Were used twenty Nellore heifers at 8.5±0.06 months of age, with an initial average body weight of 241.5±4.71 kg. The animals were distributed in a completely randomized deseing with two treatments and ten replicates. Two protein sources in the supplements were evaluated: 1) Soybean meal (SBM), and 2) Soybean meal + Wheat bran + Urea (SBM+WB+U). Results. Crude protein (CP) and organic matter intakes were higher (p<0.05) for heifers from SBM compared with SBM+WB+U. The CP digestibility was increased (p<0.05) with SBM supplementation. Mean blood concentrations of glucose, cholesterol, serum urea nitrogen, and total proteins were not affected (p>0.10) by protein sources. In the same way, daily weight gain and final body weight were not influenced (p>0.10) by protein sources. Conclusions. The supplementation with soybean meal or wheat bran with urea in association with soybean meal in multiple supplements for grazing cattle provides similar productive and nutritional performance and metabolic profile in beef heifers.
Evaluating Epidemiological Risk by Using Open Contact Tracing Data: Correlational Study (Preprint)
Authors: Piotto Stefano , Di Biasi Luigi , Marrafino Francesco , Concilio Simona
Published: March 2021

BACKGROUND

During the 2020s, there has been extensive debate about the possibility of using contact tracing (CT) to contain the SARS-CoV-2 pandemic, and concerns have been raised about data security and privacy. Little has been said about the effectiveness of CT. In this paper, we present a real data analysis of a CT experiment that was conducted in Italy for 8 months and involved more than 100,000 CT app users.

OBJECTIVE

We aimed to discuss the technical and health aspects of using a centralized approach. We also aimed to show the correlation between the acquired contact data and the number of SARS-CoV-2–positive cases. Finally, we aimed to analyze CT data to define population behaviors and show the potential applications of real CT data.

METHODS

We collected, analyzed, and evaluated CT data on the duration, persistence, and frequency of contacts over several months of observation. A statistical test was conducted to determine whether there was a correlation between indices of behavior that were calculated from the data and the number of new SARS-CoV-2 infections in the population (new SARS-CoV-2–positive cases).

RESULTS

We found evidence of a correlation between a weighted measure of contacts and the number of new SARS-CoV-2–positive cases (Pearson coefficient=0.86), thereby paving the road to better and more accurate data analyses and spread predictions.

CONCLUSIONS

Our data have been used to determine the most relevant epidemiological parameters and can be used to develop an agent-based system for simulating the effects of restrictions and vaccinations. Further, we demonstrated our system's ability to identify the physical locations where the probability of infection is the highest. All the data we collected are available to the scientific community for further analysis.
Is Psi a Synchronization of Reciprocal Resonate Actions? Telepathy, and Intuition, as Examples
Authors: Zahran Prof. Dr. Samah K.
Published: March 2021

This paper suggests a hypothesis about the nature “Psi”; psychical experience. The suggested hypothesis concluded from rational logical introduction and related studies, as well. By inductive methodology, concluded from this paper that we are all linked to coherent neural networks that work in synchronized and reciprocal way. Our mirror neurons resonate and synchronize actions to join us with the whole, at anytime, anywhere, causing communication obviously noticed in Psi experiences. This communication happens when we have massive, urgent need with no ability to feed by regular ordinary daily common ways.
Natural Recovery and Supportive Community Networks
Authors: Scoles Pascal
Published: March 2021

The natural recovery process of “maturing out” appears to be an active process of renewal and growth, leading to transformative growth that involves the individual’s body, mind, and spiritual dimensions. If spontaneous or “maturing out” recovery accounts for about 4 to18% of the alcohol and other drug (AOD) challenges to the field of behavioral health treatment, how does one effectively partner with the other 82% who have alcohol and other drug issues? To answer this concern, we must ask a few more questions. (1) What developmental factors influence growth? (2) What social determinants of health enhance recovery? (3) What is a supportive community network? and (4) What constitutes evidence-based practice? When one only looks at the biological reasons for behavioral health challenges, the assumption is that getting well and overcoming deficiencies is a function of the individual rather than the system of care. This kind of narrow perspective has contributed to a behavioral health delivery system that continually struggles to provide an integrated, comprehensive care model. This restrictive thought process undermines individuals’ confidence to change and is unduly dismissive of community leaders’ efforts.
Communicative Approach Strategies for English Language Teaching
Authors: ZIMBA Miriam M. , TIBATEGEZA Eustard R.
Published: March 2021

This paper focuses on Communicative Approach strategies used by teachers in teaching English in secondary schools, and the challenges teachers and students face in using such strategies in classes. Data collection was done in four government secondary schools within Mzuzu City in Malawi. Data were collected by using questionnaires, interviews and classroom observations. Key findings reveal that most teachers frequently use communicative approach strategies in teaching English language such as pairing, debates, group discussions, filling in gaps, and dramatization. The study indicates that even though communicative approach strategies are used in classrooms, there are some challenges which hinder the implementation, namely inadequate time to engage students in class, inadequate teaching and learning resources, failure to assist students with disabilities, and overcrowded classrooms. The paper recommends that the government of Malawi through the Ministry of Education should work on the challenge of overcrowded classes and provide enough teaching and learning materials in schools in order to implement communicative approach strategies effectively.
El sujeto del discurso científico

Published: March 2021

En este ensayo procuro demostrar que las fuentes de la subjetividad no están en las marcas que inevitablemente plasme el investigador científico en su discurso, sino en el rigor y claridad del mismo. Defiendo que una dosis de subjetividad en algunas etapas del proceso de producción científica no solo es saludable, sino inevitable, por lo que no tiene fundamentación científica la cancelación del sujeto de la investigación y la prescripción absoluta de su eventual aparición como sujeto gramatical de algunos enunciados. Señalo como fuente de subjetividad perniciosa la autorreferencialidad, la modalización, el sesgo de confirmación, la ponderación subjetiva, las expresiones sin fundamentos empíricos, los prejuicios y adjetivos y los adverbios de cuantificación o ponderación. Mis reflexiones tienen como base metodológica y sustentación teórica el análisis crítico del discurso y la filosofía de la ciencia.

Pengetahuan dan Sistem Pengelolaan Pertambangan Minyak Rakyat di Gampong Alue Dua Aceh Timur
Authors: Fitriani  , Ade Ikhsan Kamil
Published: March 2021

This article discusses the knowledge of community oil miners in the People's Mining in Alue Dua Village, Rantau Peureulak District, East Aceh Regency. The author collects data using participatory observation, in-depth interviews and corroborates it by studying literature. The results showed that the knowledge of miners in Gampong Alue Dua was formed along with the history of the emergence of mining in Peureulak, especially when the oil companies entered to take samples of land as proof that the Peureulak area has the potential to contain oil, and also because of self-taught learning. For miners, there are 4 special signs in identifying land that has the potential to contain oil: 1) the land selected for drilling that is close to and is still in the same lane as the Dutch heritage lake. 2) The distance between the land which is the drilling position and the Dutch heritage lake is about 100-150 meters. 3) Selection of old wells or Dutch heritage ponds with the category of no longer active. 4) Get back to the miners' technicians at work.

Abstrak

Artikel ini membahas tentang pengetahuan penambang minyak rakyat yang ada di Pertambangan Rakyat di Gampong Alue Dua, Kecamatan Rantau Peureulak, Kabupaten Aceh Timur. Penulis mengumpulkan data dengan cara observasi partisipasi, wawancara mendalam dan menguatkannya dengan studi literatur. Hasil penelitian menunjukkan bahwa pengetahuan penambang di Gampong Alue Dua terbentuk seiring sejarah kemunculan pertambangan di Peureulak, terutama saat masuknya perusahaan minyak untuk mengambil sempel tanah sebagai pembuktian bahwa daerah Peureulak berpotensial mengandung minyak, dan juga karena faktor belajar secara otodidak. Bagi para penambang, terdapat 4 tanda khusus dalam mengenali lahan yang berpotensial mengandung minyak: 1) lahan yang dipilih untuk melakukan pengeboran adalah lahan yang dekat dan masih satu jalur dengan telaga peninggalan Belanda. 2) Jarak lahan yang menjadi posisi pengeboran dengan telaga peninggalan Belanda sekitar 100-150 meter. 3) Pemilihan sumur tua atau telaga peninggalan Belanda dengan kategori sudah tidak aktif lagi. 4) Kembali pada teknisi para penambang dalam bekerja.
Punicalagin Reverses Methotrexate-Induced Nephrotoxicity by Attenuating Oxidative Stress, Inflammation and Apoptosis
Authors: Aladaileh Saleem H. , Swailmi Farhan K. Al- , Abukhalil Mohammad H. , Shalayel Mohammed H.
Published: March 2021

Methotrexate (MTX) is a trusted anticancer agent; however, its multi-organ toxicity limits its clinical application, including nephrotoxicity. Punicalagin (PUN) is an ellagitannin found in the fruit peel of Punicagranatum with anti-inflammatory and antioxidant properties. The present study aimed to investigate the renoprotective effects of PUN in a well-established rat model of MTX-induced nephrotoxicity. Rats were divided randomly into four groups (six animals per group) as follows: the first group (control) was a normal control group. The second group (PUN) received PUN (30 mg kg- 1 day- 1) daily through oral gavage for 10 consecutive days. The third group (MTX) a single i.p. injection of MTX (20 mg/kg) on day 7. The fourth group (PUN + MTX) received PUN (30 mg kg- 1 day- 1) via oral gavage for 10 consecutive days and a single i.p. injection of MTX (20 mg/kg) on day 7. MTX-induced nephrotoxicity was associated with increased creatinine and urea in the serum. MTX also resulted in increased oxidative stress as evidenced by elevated malondialdehyde and protein carbonyl levels along with decreased glutathione content and superoxide dismutase and catalase activities in the kidney. Moreover, renal tissues were characterized by increased proinflammatory cytokines, cytochrome c and caspases-3, indicating increased inflammation and apoptosis in the kidney. PUN pretreatment prevented kidney injury, oxidative stress, inflammation and apoptosis, and enhanced antioxidant defenses in the kidney. Collectively, these findings indicate that PUN may represent a novel renoprotective strategy against MTX-induced oxidative stress, inflammation and apoptosis in the kidney, which deserves further exploration in future studies.
How to Make Performing Arts Survive Time and Become an Accessible Archive: An Attempt to Register Performing Art’s Creation
Authors: Greta Pundzaite
Published: March 2021

While the momentariness of performing arts might be one of the most (if not the most) fascinating aspect of the art form allowing to experience the fragility of live events and creatures themselves, the context they depend upon, it is also approached as a great obstacle for a smooth evolution (or rather enriching and intriguing transformation) of the art form. It is believed that not having a medium that allows registering and archiving pieces of creation causes a constant loss. Having in mind that a certain amount of loss of any art form is inevitable, the performing arts situation is understood as quite unbalanced, or rather, problematic from the artist’s point of view. It is believed that not being able to access the history of creation (not from a historical but (more or less) direct contact with the creation point of view), tangles, straitens the potential of an artist, makes him/her feel the gaps of collective memory. By contemplating authenticity, repetition, difference, continuity, context and interconnection, creation is addressed as a collective and complex process. A piece of performing arts itself is approached in the same way (consisting of various interconnected elements), suggesting a similar approach towards the registration process. Work consists of the initial version of performance registration structure/system CYCLE and the essay ‘How to Make Performing Arts Survive Time and Become an Accessible Archive: An Attempt to Register Performing Art’s Creation’.

Published: March 2021

A comprehensive evaluation indicator system is needed to provide a
integrated assessment of the degree of sloped cropland degradation. We
employed bibliometrics to perform statistical analysis on research
studies involving cropland degradation. Frequency analysis was then used
to identify high-frequency indicators with which to construct a total
index set (TIS) for evaluation of the degree of sloped cropland
degradation in black soil region. In addition, soil measurement data
from sloped cropland in Baiquan and Keshan Counties, Heilongjiang
province, China, were used as a basis to construct a minimum index set
(MIS). The TIS included A-horizon thickness, clay content, organic
matter content, pH, slope gradient, ridge-slope angle, gully density,
bulk density, large water-stable aggregate content, soil cation exchange
capacity, and crop yield. The first six of these were included in the
MIS. In the studied area, undegraded soil, mildly degraded soil, and
moderately degraded soil and above accounted for 7%, 48% and 45% of
investigated sloped croplands, respectively. Slope gradient is one of
the main factors affecting soil degradation. Soil degradation mainly
presented as worsening of soil physicochemical characteristics. In
addition, downslope and small-angle ridge cultivation are benefit for
soil organic matter maintenance and the soil structure and nutrient
retention capacity is better than soil with contour or large-angle ridge
cultivation. The reason might be that downslope and small-angle ridge
cultivation are usually employed on soil with small slope. The study
results provide a scientific basis for improving the quality and
productivity of sloped cropland in black soil region.
COVID-19 and lung ultrasound: reasons why pediatricians can support adult COVID-19 units during critical epidemiologic periods
Authors: Rose Cristina De , Pierantoni Luca , Buonsenso Danilo
Published: March 2021

The massive raise of COVID-19 cases all over the world is leading to
unprecedented pressures on healthcare services. Growing evidence is
highlighting that COVID-19 is a systemic condition that requires doctors
with multiple expertise. Paediatricians are trained in these skills.
Considering the issue of staff shortage that is facing every country in
the world, and the complexity of COVID-19, paediatricians may represent
an important source of ready and skilled specialists that can quickly
translate the paediatric practice in the COVID-19 care. We report our
experience of paediatricians engaged in the fight against COVID-19
within adult COVID-19 wards. In particular, we focus on the importance
of a skill of some paediatricians in their clinical practice, namely the
use of lung ultrasound which has also become fundamental in the
management of adult patients with COVID-19, especially for some
categories such as pregnant women.

Published: March 2021

Background:Although the sensitivity of third generation anti-HCV CIA
tests is high, false positivity rates, especially in populations with
low HCV infection endemicity, are still high. Objectives:We aimed to
determine the S/Co cut-off value of anti-HCV in the diagnosis of real
positive patients based on the CIA test kit absorbance routinely used in
our laboratory and to reveal the potential cost effectiveness of
confirmatory tests for false positive samples. Methods:All anti-HCV CIA
test results which were performed in the microbiology laboratory of our
hospital between 2016-2019 were retrospectively screened and S/Co values
of the patients were recorded. Among these, the results that were
confirmed with HCV-RNA real-time PCR test were included. Patients who
were previously diagnosed and treated were excluded. Results:A total of
257 patients, who were tested for HCV-RNA after reactive anti-HCV test
results, were included in the study. Of the cases, 84(32.68%) had
positive HCV-RNA. According to the ROC analysis, the optimal S/Co value
was 8.58 with the sensitivity and specificity values 95.24% and
85.55%, respectively. According to this 8.58S/Co value, anti-HCV test
was reactive in 105 cases and 80(76.2%) of these cases had active HCV
infection. In order to prevent the false-negativity, the additional cost
of using 1.0S/Co value to our institution was 4114.64USD, meaning that
we spent 1028.66USD to diagnose per true-case of active HCV infection
when using 1.0S/Co value. In our institution, approximately 6.25 working
hours are spent to finalize the HCV-RNA PCR test. The hours spent for
S/Co of 1.0 and 8.58 were 1606.25 and 658.25, respectively.
Conclusions:False positive anti-HCV results are an economic burden on
health economics of countries. At least, different S/Co values might be
used in accordance with the purpose of the screening (like blood donors
or pre-operative screening) and prevalence of HCV infection in different
laboratories and different populations.
Supra-annular aortic valve replacement: technique and early outcomes
Authors: Shraer Nathanael , Ramadan Ramzi , Azmoun Alexandre , Guihaire Julien
Published: March 2021

OBJECTIVES: The supra-annular aortic valve replacement (SA-AVR) allows
for implantation of larger prostheses. We describe the technique, early
post-operative outcomes and hospital mortality. METHODS: Patients who
underwent SA-AVR with the Carpentier-Edwards Magna Ease bioprosthesis
between December 2010 and December 2017 were retrospectively reviewed.
The prosthesis was sutured to the aortic annulus along the coronary
sinuses, and in a supra-annular position along the non-coronary sinus.
RESULTS: 115 patients were included (mean age: 71,6 years ± 9,4). Mean
bioprosthesis diameter was 23,3 ± 1,7 mm. Four early deaths were
observed in the ICU. Early post-operative complications included:
re-operation for bleeding (n=6), tamponade (n=7), permanent
atrioventricular block (n=4) and hemodialysis (n=2). In-hospital
mortality was 3,48%. Postoperative echocardiography showed a marked
decrease in the mean left ventricle – aorta gradient (50,4 ± 16,1 mmHg
vs 11,3 ± 4,05 mmHg). CONCLUSION: SA-AVR is safe and associated with
favourable immediate outcomes in patients with small aortic annulus.

tightness and pain. She had undergone aortic valve replacement for
aortic stenosis at the age of 18 years. Transthoracic echocardiography
showed left ventricular asynergy and a high aortic valve pressure
gradient. Thus, structural valve deterioration was diagnosed. Coronary
computed tomography and coronary angiography revealed left main trunk
ostial stenosis that had caused acute anteroseptal myocardial
infarction. Urgent surgery revealed pannus formation around the
prosthetic valve and covering the ostium of the left main trunk. A
Bentall procedure and coronary artery bypass grafting were performed.
The postoperative course was uneventful.

Background: Functional mitral regurgitation (FMR) is common in patients
with myocardial infarction or dilated cardiomyopathies, and portends a
poor prognosis despite guideline-directed medical therapy. Surgical or
transcatheter mitral repair for FMR from recent randomized clinical
trials showed disappointing or conflicting results. Aims: To provide an
update on the role of surgical repair in the management of FMR.
Materials & Methods: A literature search was conducted utilizing
PubMed, Ovid, Web of Science, Embase and Cochrane Library. The search
terms included secondary/functional mitral regurgitation, ischemic
mitral regurgitation, mitral repair, mitral replacement, mitral
annuloplasty, transcatheter mitral repair, and percutaneous mitral
repair. Randomized clinical trials over the past decade were the
particular focus of this current review. Results: Recent data underlined
the complexity and poor prognosis of FMR. Guideline-directed medical
therapy and cardiac resynchronization, when indicated, should always be
applied. Accurate assessment of the interplay between ventricular
geometry and mitral valve function is essential to differentiate
proportionate FMR from the disproportionate subgroup, which could be
helpful in selecting appropriate transcatheter intervention strategies.
Surgical repair, most commonly performed with an undersized ring
annuloplasty, remains controversial. Adjunctive valvular or subvalvular
repair techniques are evolving and may produce improved results in
selected FMR patients. Conclusion: FMR resulted from complex
valve-ventricular interaction and remodeling. Distinguishing
proportionate FMR from disproportionate FMR is important in exploring
their underlying mechanisms and to guide medical treatment with surgical
or transcatheter interventions. Further studies are warranted to confirm
the clinical benefit of appropriate surgical repair in selected FMR
patients.

Pelvic arteriovenous malformations (pAVMs) are rare lesions that
sometimes pose diagnostic challenges. We report on a 50-year-old woman
with a pAVM presenting with only abdominal distension and bloating. The
diagnostic tool was color Doppler transvaginal ultrasonography. Surgical
excision of the AVM was performed, and there was no subsequent
recurrence.
Could iron-chelation with EDTA and bloodletting/transfusion be a therapeutic option in COVID-19 worst scenario? Proposal for a protocol

Published: March 2021

COVID-19 is a complex, multi-organ disease where lungs are primarily affected, resulting in a form of ARDS in the later stages. In fact, a relevant role has been attributed to iron dysmetabolism and series of literature data highlight a clear-cut alteration in a few related parameters; significantly high figures of ferritin, hepcidin, red blood cell width distribution, lactate dehydrogenase and lactate, in combination with low levels of serum iron and transferrin, have been repeatedly reported in patients affected by Sars-Cov-2 infection at later stages. Overall, these alterations have a negative prognostic value, indicating a pattern of ferroptosis and of a possible dysfunctional hemoglobin, with pro-coagulant and pro-inflammatory repercussions. Different pathomechanisms have been proposed, from erythrocyte attack and an hepcidin-mimetic action of the viral spike proteins, to a more general iron and calcium deregulated intracellular accumulation. Iron chelation has been advocated as one of the possible treatments of COVID-19 and CaNa2ethylendiaminetetraacetic acid (EDTA) is known as a safe and effective mineral-chelator. In this review the authors propose an EDTA-based therapeutic protocol for those patients in most critical stages and admitted to intensive care unit, with the aim to reduce intracellular and blood ferritin overload. Bloodletting and blood transfusion have proved to be beneficial in patients with viral disease-associated iron accumulation. The inclusion of these two procedures in the proposed protocol aims at improving oxygenation by new normo-functioning hemoglobin, while decreasing toxic hyperferritinemia and interleukins. Lastly, a few specific compounds are also taken into consideration to synergistically complement EDTA infusion. A series of technical details are provided for the possible use of the protocol in clinical practice.

Purpose: The purpose of this paper is to systematically review the literature on the professional development of educational administrators in the world, based on empirical and theoretical evidence with special reference to educational administrators and school principals in several countries. Design/Methodology: An interpretative analysis on literature covering professional development, pre-service training, in-service training programmes, mentoring, models of education leaders, coaching and the history of education in Sri Lanka and also the background information of the Education Administrative Service in Sri Lanka is carried out. Findings: Training and professional development date back to several centuries and it was found that the influence of imperialists, mainly the British was dominant in the Sri Lankan modern education system and professional development programmes. Sri Lanka continues to implement training and development with the least changes in contents and scopes compared to the past. It was further found that authorities paid little attention to the effectiveness of the training and development but rather were concerned about the compliance requirements. At present, education leaders undergo training programmes, and improvements in leaders are also seen at varying degrees. The study finds that educational leaders who are good at leadership skills and competencies produce better results in terms of both students’ performances and school management. However, though the use of technology in training was trivial, the need for more sophisticated, comprehensive, and sustainable training for educational leaders for better performance is highlighted. Practical implications: Provision of training and development is perceived by authorities as a practice and not as a key driver of improving school performance and effective management. The outcome of the study can be used to further enhance and implement professional development and training programmes for educational leaders with an outcome-oriented approach. Therefore, the findings will help lay a foundation for policymaking and their implementation can be broadened to enhance the quality of education in Sri Lanka.

Authors:   University of Dundee, UK, Fragouli Evangelia
Published: March 2021

Internationalized curriculum development is critical to all institutions aiming to approach internationalisation coherently. Research on the internationalisation of the curriculum (IoC) focuses on the curriculum concept encompassing all aspects of learning and teaching (Kemmis & Fitzclarence, 1991). It works at formal, hidden and informal levels. The present work is a critical review of a research piece opinion by Sue Robson (2015) ‘Internationalisation of the Curriculum: Challenges and opportunities’ emphasising the contribution to this matter of the Higher Education Academy (HEA internationalisation framework but also showing what is missing and needs to take place concluding that a more comprehensive framework would have better-added value for internationalising higher education
O LUGAR DA EDUCAÇÃO DAS RELAÇÕES ÉTNICO-RACIAIS NOS PROJETOS POLITICO-PEDAGÓGICOS DE DUAS ESCOLAS PARAENSES

O objetivo deste artigo, é analisar o lugar da Educação das Relações Étnico-Raciais (ERER) nos Projetos Político-Pedagógicos (PPPs) de duas escolas paraenses, com base em seus documentos escolares, PPPs e do Plano de Desenvolvimento Institucional (PDI) de uma delas. Recorremos a Bardin (2016) para a categorização dessa empiria. Acionamos Veiga (2003) para a ponderação sobre Projeto Político-Pedagógico; e sua implementação em Gomes (2012). Para a ERER e a escola, recorremos a Coelho e Coelho (2013, 2018). Concluímos que o trabalho realizado por ambas as escolas possibilita, ainda que de forma pontual, uma discussão junto aos discentes, com vistas à problematização da identidade, racismo e discriminação, embora não reflita a institucionalidade e a implementação da ERER nos documentos escolares.

HOTS-Based Analysis on English Reading Comprehension Formative Assessment
Authors: As Sabiq Agus Husein , Ardiana Aulia Putri
Published: March 2021

The Ministry of Education and Culture has directed the assessment model at Higher-order Thinking Skills (HOTS), but in reality, students are less trained in solving the model of this assessment. This cause the learning outcomes of students tend to be less by the teachers. Therefore, the assessments made by teachers should be on the basis of HOTS. This study aimed to find out the assessment level of reading comprehension formative assessment administered by the English teachers in reference to HOTS. This research is classified as quantitative descriptive research involving two English teachers in SMA 2 Brebes. The items of formative assessment are analyzed using the cognitive level of the revised Bloom. As a result, the researchers find that the questions categorized as HOTS level obtain 18 out of 91 questions or (19.78%). Meanwhile, 73 out of 91 questions or (80.22%) are categorized as LOTS level. It can be implied that HOTS based questions are not at the dominant level. However, the test meets the requirements of the minimum standard by the Ministry of Education and Culture in the National Exam (UN) that is between 15%-20%. But, it is still a little bit less to the position of PISA questions which requires 20%.
