AbstractBackground: The quarantine associated with the COVID-19 pandemic forced dental schools to suspend their clinical training and to shift to distant learning methods. The aim of this study is to investigate the impact of COVID-19 quarantine on the preparedness of dental graduates and to explore the efficacy and limitations of online education from students’ perspectives. Methods: the questionnaire distributed to dental students comprised of two main sections; first part covered the online education experience and the second part measured the level of preparedness for a range of cognitive, communication and professional skills. Results: the survey yielded a response rate of 72%. The majority of students (77%) agreed that they missed educational experiences as a result of the lockdown. More than half of them felt less motivated in following-up with distant e-learning and believed that online assessment is not a good method for evaluation. A high percentage of the students (66%) thought that online group discussions has a positive value whilst 67% preferred online lectures compared to theatre lectures. Majority of students particularly 5th year (78.7%) (p<0.001) stated that the quarantine increased their collaboration with their colleagues. According to 87% of students, the experience most negatively affected was their clinical training.In general, students showed satisfactory preparedness related to a range of attributes and professional skills, however, nearly two-thirds of them prefer to be mentored and favor a structured year of residence. Conclusions: Data showed that students partially appreciated the online system, whereas they did not consider it a substitute for face to face clinical practice. The overall preparedness level was promising, however, some skills regarding evidence-based practice need consolidation. Students had reservations regarding independent practice following graduation.

Several reports associated the severe Coronavirus disease-2019 (sCOVID-19) with secondary-haemophagocytic lymphohistiocytosis (sHLH) and proposed the HScore table for sCOVID-19 patients. We conducted a meta-analysis to found the possible association of HScore parameters with severity in COVID-19 patients. Systematic search was performed in Medline (PubMed), EMBASE, and Cochrane databases using all HScore and COVID-19 keywords. The records were screened based on inclusion/exclusion criteria. Random/fixed-effect models were employed. The pooled mean differences were estimated for continuous parameters. The pooled odds-ratio was estimated for fever. Eighteen studies met the criteria and included in the meta-analysis (2459 patients). Significant higher levels of leukocyte, neutrophil, aspartate-transaminase (AST), ferritin, and fibrinogen, as well as lower level of lymphocyte, platelet, and hemoglobin were found in sCOVID-19 patients compared to non-severe ones. Fever was nearly associated with 2 times increased odds of sCOVID-19 (p-value = 0.051). Lymphopenia, thrombocytopenia, hypohemoglobinemia, hyperferritinemia, high levels of AST, and fever are common features of both sCOVID-19 and HLH. However, leukocytosis, neutrophilia, and hyperfibrinogenemia found in sCOVID-19 contrast with HScore. Conclusively, HScore parameters could be risk factors for the severity of COVID-19. However, some parameters’ roles are contradictory, suggesting further investigation and a new way of HScore interpretation for sCOVID-19 patients.
The Minerals of Lithium
Authors: Grew Edward S.
Published: August 2020

Lithium is rare in the cosmos, but the formation of continental crust has concentrated lithium into economic deposits. The 124 recognized Li mineral species occur largely in four geologic environments: (1) lithium–cesium–tantalum (LCT) granitic pegmatites and associated metasomatic rocks; (2) highly peralkaline pegmatites; (3) metasomatic rocks not directly associated with pegmatites; (4) manganese deposits. The geologically oldest Li minerals are reported from LCT pegmatites and date to 3,000–3,100 Ma, a critical period in the evolution of the continental crust and the rate of its generation. This suggests a link between the earliest appearance of LCT-family pegmatites and the onset of plate tectonics, consistent with the correlation between the observed abundance of LCT-family pegmatites and supercontinent assembly.

Published: August 2020

Financial conglomerates and bank competition play a significant role in developing efficiency levels and increased risk exposure. This study aims to formulate a conceptual model of the policy’s impact of financial conglomerates and bank competition on bank efficiency and stability risk. This research is conducted using data samples from 90 commercial banks in Indonesia from 2010 to 2017. The empirical analysis is carried out using the dynamic data panel or Generalized Method of Moments (GMM). The study results show that policies of financial conglomerates and competition have a positive effect on banking efficiency. These results support previous empirical studies, where financial conglomeration, in general, can improve banking efficiency. Furthermore, it is found that the interaction between financial conglomerates and competition has a positive effect on banking stability. The implication of this research shows that the potential risks that cause distortion become irrelevant when the banking structure is more competitive. Furthermore, this study recommends the need to build the ideal financial conglomerate institutional structure to strengthen and encourage the role of more competitive banks.

Objective:

The aim of this study was to describe the clinical characteristics of patients that have had a heart failure with preserved ejection fraction (HF-pEF) and to identify the factors associated with 5-year mortality and readmission.

Methods:

A prospective cohort study was conducted of patients followed by the Heart Failure Unit of the Internal Medicine Department. Clinical characteristics and outcomes were collected. Univariate and multivariate analyses were performed in order to identify factors associated with 5-year mortality and readmission.

Results:

A total of 209 patients with HF-pEF were followed, 59.3% of these were women, with a mean age 79 years. The main etiology was hypertensive heart disease and a high level of comorbidity (chronic renal failure, hypertension and atrial fibrillation) was observed. The 5-year mortality was 55.5%; the related variables were anemia (hazard ratio [HR]=1.7; 95% confidence interval [CI]: 1.2-2.5), in patients being treated with statins (HR=0.7; 95%CI 0.5-0.9) and spironolactone (HR= 1.6; 95% CI: 1.1-2.3); 24.5% of patients had >2 admission in 5 years, with the main related factors being atrial fibrillation (HR=2.7; 95%CI: 1.4-5.5), anemia (HR=1.9; 95%CI:1.0-3.3) and were being treated with spironolactone (HR=2.1; 95%CI:1.2-3.7).

Conclusion:

Patients with HF-pEF are old and present a high level of comorbidity. Furthermore, they have a high 5-year mortality and readmission rate. The only factor associated with lower mortality was the treatment with statins. The use of spironolactone was associated with a higher mortality risk.

Published: August 2020

Purpose:

The aim was to report on the visual outcomes and safety of myopic LASIK performed in patients with corneas of central thickness below average(<540μm) and normal topography.

Methods:

This is a retrospective cohort study conducted at a private practice setting on Mexican Hispanic patients who underwent myopic LASIK between January 2014 and January 2015. An analysis of records of patients >18 years-old with previous normal topography, stable refraction, corrected visual acuity ≥ 20/20 (Snellen), Central Corneal Thickness (CCT) < 540μm and at least 12 months follow up after surgery was conducted. The main outcome measures were standard visual outcomes (efficacy, safety, refractive stability) and Percent Tissue Altered (PTA) analysis was conducted.

Results:

A total of 51 patients (102 eyes) were included; 56% (n=57) were female. The mean age was 26.52 ± 8.06 (range 18-55 years) with a mean follow up of 13.9 ± 1.2 months. Preoperative CCT was 515.44 ± 17.87μm (range 452- 540μm), with a mean refractive spherical equivalent (SEQ): -4.08 ± 2.17 D (range -0.75 to -9.75 D), and mean refractive cylinder: -1.44 ± 1.29 D (range 0.00 to -6.00 D). Mean predictability of postoperative SEQ was -0.20 ± 0.40 D (range -1.25 to +1.25). Postoperative SEQ was ±0.50 D in 71%, ±1.00 D in 93% of the eyes. Postoperative uncorrected distance visual acuity was ≥20/20 in 78% and ≥20/25 in 95%. One line of CDVA was lost in 3% of the eyes, no eyes lost ≥2 lines. No ectasia cases were observed during follow-up.

Conclusion:

LASIK surgery in Mexican Hispanic patients with thinner than “normal” corneas (<540 μm) is safe, efficient and predictable at 1 year follow up for myopic refractive corrections with no evidence of postoperative keratectasia.
Comparisons Between Braking Experiments and Longitudinal Train Dynamics Using Friction Coefficient and Braking Pressure Modeling in a Freight Train
Authors: Choi Don Bum , Jeong Rag-Gyo , Kim Yongkook , Chai Jangbom
Published: August 2020

Background:

This paper describes the predictions and validation of the pneumatic emergency braking performance of a freight train consisting of a locomotive and 20 wagons, generally operated in Korea. It suggests the possibility of replacing the expensive and time-consuming train running tests with longitudinal train dynamic simulations.

Methods:

The simulation of longitudinal train dynamics of a freight train uses the time integration method of EN 14531. For reasonable simulation results, the characteristics of the train and brake equipment must be considered. For the train characteristics, specifications provided by the vehicle manufacturer are used. The braking characteristics are analyzed by friction coefficient tests and a braking pressure model. The friction coefficients of a locomotive and wagons are tested with a dynamo test bench and statistically expanded to account for variability. Freight trains should take into account the braking delay time. To reflect this in the simulation, the brake cylinder pressure pattern model uses pressures and exponential empirical equations measured at selective positions in a train of 50 vehicles. The simulation results are validated in comparison with those of the braking tests of a freight train consisting of 1 locomotive and 20 wagons.

Results:

The results of the longitudinal dynamics simulation show very similar results to the running test results based on the speed profile and braking distance.

Conclusion:

In particular, the statistical expansion method of the friction coefficient enables robust prediction of the distribution of the braking distance. The simulation can reduce or make up for costly and time-consuming repeated braking tests and reduce the risks that may arise during testing.

Information about Sports Related Concussion and Return to Play Rules in Youth Soccer, Rugby and Handball on Websites of German Sports Clubs (Preprint)
Authors: Rihani Laura , Usinger Jennifer , Jungbäck Nicola , Stumm Gabriele , Schulz Thorsten , Schlegel Jürgen
Published: August 2020

BACKGROUND

Sports-related mild traumatic brain injuries (sports related concussion, SRC) have received increasing attention since neurodegenerative processes have been linked to repetitive SRCs. Return-to-Play (RTP) rules have been established for medical advised return into sports activities after concussion, but it is not clear if these rules also reach the sports clubs and its young athletes.

OBJECTIVE

In youth sports, athletes and their parents search the internet for advice after SRC. We therefore investigated which websites of German sports associations and clubs in football (soccer), handball and rugby offer information on SRC and RTP rules.

METHODS

The systematic analysis included websites of local football, handball and rugby clubs in two comparable regions in Southern Bavaria and Lower Saxony. The websites of the regional and the German umbrella associations were also included into the study. Eight criteria of the revised Sport Concussion Consensus Statement served as standard for the evaluation according to the protocol published by Swallow et al. (J Neurosurg Pediatr, 2018).

RESULTS

No information on RTP rules or the topic “sports-related brain injuries” could be found on any of the clubs’ websites. Only the Bavarian Football Association and the Rugby Association sporadically provided information on the topic. The German umbrella associations in football and rugby take up international documents and regulations of the European and the world associations. No information could be found at the German Handball Association.

CONCLUSIONS

The topics of sports-related brain injuries and RTP rules are mostly neglected on the analysed Websites. This is remarkable, as there are clearly defined consensus guidelines which are widely accepted in international comparison. Especially in the USA, online information on this topic has become standard.

Published: August 2020

El objetivo de este estudio fue comprender las prácticas de autodenominación en aplicaciones sociales de interacción para desarrollar una clasificación de la homosexualidad masculina, sexualidades alternativas y deseo en Brasil. El presente estudio cualitativo, basado en una investigación documental y bibliográfica en forma de cartografía, trabajó con un corpus de 1 732 palabras extraídas de 1 005 perfiles de usuario en Scruff (una aplicación móvil de interacción social utilizada por hombres que buscan relacionarse afectiva y sexualmente con otros hombres). Se utilizó el software de minería de datos Voyant Tools, el cual permitió la visualización de correlaciones, coincidencias, flujos y dispersión de temas textuales, así como análisis de contenido para identificar los principales temas del corpus. Se concluye que, en su autoclasificación, algunos sujetos usan términos que provocan ligeros cambios de significado, a la vez que se distancian de una identidad gay y refuerzan su masculinidad basándose en estereotipos y prejuicios.

Almejamos analisar a série de filmes nomeada como “Trilogia do Cárcere”, filmada por Aly Muritiba em uma penitenciária no estado do Paraná, e colocá-la em diálogo com a sociologia e a antropologia brasileiras. Dessa forma, acreditamos que evidenciar as informações existentes nessas obras cinematográficas pode ser fonte potente para a análise empírica de estudos sobre prisão. Ao problematizar as referidas obras de arte à luz de dados oriundos de pesquisas sociológicas e antropológicas, desejamos evidenciar algumas narrativas fílmicas sobre o cárcere como formas específicas de representação e, assim como a sociologia e a antropologia que, mesmo sendo descrições parciais, podem ser adequadas para compreender ações e relações dentro e fora do ambiente prisional.

O texto demonstra, a partir da implementação das Usinas Hidrelétricas Santo Antônio e Jirau no rio Madeira (Rondônia, Brasil), os caminhos institucionais e discursivos específicos adotados na expansão dessa fronteira, que precificam e nivelam por baixo padrões de proteção ambiental e de direitos sociais e culturais vigentes no país. Verificamos como se enredaram esses processos em pesquisa e diálogo com os moradores da comunidade Maravilha. Nesse contato percebemos que, apesar das sucessivas desterritorializações impostas à comunidade, prossegue a trama por sua sobrevivência econômica, social e cultural. Nosso objetivo foi definir os marcos dessa trama, contribuindo para a reflexão, valorização e proteção de âmbitos culturais realçados no envolvimento efetivo dos moradores na construção de suas narrativas e na singularização de seus lugares e patrimônios.

Authors: AlHares Aws , Al-Hares Osama M.
Published: August 2020

The current study evaluated the influence of corporate governance mechanisms (CGM) from 130 banks from 13 Middle East and North Africa (MENA) countries. The goal was to analyze their risk disclosure practices from 2012-2019 and understand the impact of corporate governance (CG) on the level of bank risk disclosure. The current findings reveal a positive association between the level of bank-risk disclosure and 1) the presence of Sharia supervisory board; 2) the ownership of structure at the bank level; and 3) control of corruption at the country-level. The study has implications for developing, implementing, and enforcing governance standards at the corporate and national levels that are relevant to corporate boards, investors, governments, and regulatory authorities.

Filosofía política en el pensamiento neoclásico de Eugenio Trías: Una lectura de El artista y la ciudad
Authors: Parra José Daniel
Published: August 2020

En El artista y la ciudad, el filósofo Eugenio Trías propone una recuperación ontológica de la relación entre eros y poiesis. Plantea esta aproximación como antídoto frente al desencantamiento del mundo que, a su juicio, se deriva del dualismo moderno que se manifiesta en la distinción mecánica entre producción y deseo. Para remediar el problema de la enajenación y la dispersión de la modernidad tardía, Trías retoma las figuras del artista y la ciudad como puntos de referencia que encuentran resonancias paideicas en el símbolo renacentista de la academia platónica.
Educación física y deporte trans-formado
Authors: González Garzón Junny
Published: August 2020

El siguiente documento presenta un acercamiento inicial a conceptos de diversidad sexual y su relación con la educación física y el deporte, enfatizando en la contribución de este campo a la reproducción de algunos estereotipos relacionados con el sexo-género de las personas. Se aborda la historia de las pruebas de verificación de género, así mismo, las disposiciones del Comité Olímpico Internacional sobre la normativa para la participación de personas Trans e Intersex en competencias olímpicas. Finalmente se plantean reflexiones sobre la clasificación deportiva basada en la categoría género, de igual forma, la necesidad de proponer nuevas interacciones desde la educación físico-deportiva que reconozcan la diversidad física, biológica, fisiológica, neurológica y social inherente a las personas, teniendo en cuenta el contexto local y nacional de Colombia.

Se estudió la macromorfología de cepas de Beauveria bassiana (B1), Metarhizium anisopliae (M1) e Isaria javanica (HPI-210) y se determinó su crecimiento radial a temperaturas de 25, 28, 30, 35 y 40 °C en medio PDA suplementado con polvos de Diatraea considerata, Spodoptera frugiperda y Galleria mellonella. Los hongos se inocularon adicionando 2 µl de una suspensión con 1 x 107 esporas/ml. Después de 15 días se midió el crecimiento radial de las cepas en mm/d. Para determinar la interacción entre las tres cepas con el polvo de los tres insectos más el control PDA y las cinco temperaturas, se usó un análisis factorial 3 x 4 x 5; los datos del crecimiento de los hongos fueron analizados mediante un ANOVA y una prueba de Tukey. Se encontraron diferencias estadísticas significativas en el crecimiento a diferente temperatura, respecto al control; el crecimiento óptimo en los tres hongos fue a 28 °C, la cepa B1 suplementada con polvo de D. considerata creció 2,76 ± 0,06 mm/d, M1 con G. mellonella 2,77 ± 0,02 mm/d, y HPI-210 con D. considerata 3,27 ± 0,06 mm/d. La cepa B1 creció 0,45 ± 0,03 mm/d, M1 1,22 ± 0,0 mm/d a 30 °C, mientras que HPI-210 no creció después de 28 °C. Estos resultados sugieren que las tres cepas fueron inducidas a crecer mejor por efecto de los medios suplementados con los insectos; a 28 °C, HPI-210 presentó el mayor crecimiento/d (F = 25,24, E8, P = 0,0001) seguido de M1 y B1, mientras que M1 con suplemento de S. frugiperda creció mejor a 30 °C (F = 38,33, E8, P = 0,0001). Estos resultados de crecimiento radial, desarrollo macromorfológico y tolerancia a la temperatura permiten seleccionar a las mejores cepas para evaluar su virulencia en insectos plaga.

Caryocar brasiliense (Malpighiales: Caryocaraceae) trees, protected by Brazilian federal laws, are the main income source in many communities. The transformation of the Cerrado (savanna biome) into grazing or agricultural areas has been isolating these trees species in an agro-urban landscape. We studied the effects of environmental diversity on the abundance of galling insect communities inhabiting C. brasiliense trees in three different environments: Cerrado, pasture, and an urban area. Eurytoma sp. (Hymenoptera: Eurytomidae) adults and their galls, its parasitoid Sycophila sp. (Hymenoptera: Eurytomidae) and the predator Zelus armillatus (Hemiptera: Reduviidae) were present in larger numbers on the C. brasiliense leaflets in the urban area. The percentages of totally galled leaflets (exhibiting all kinds of galls) and the number of trees were negatively correlated. Greater habitat diversity favored that of galling insect species and their natural enemies.

Dark-Skinned Servants Through the Eyes of a White Author: a case study of K. Stockett’s Novel “The Help”
Authors: Sapozhnikova Yulia L.
Published: August 2020

If white authors speak on behalf of dark-skinned characters in their texts, African-American critics and writers often accuse them of attempting cultural appropriation. In this case, according to African-Americans, white people describe them only stereotypically and thus deprive them of a voice. Despite this, such attempts continue. In 2009, K. Stockett released her novel “The Help”, which is narrated by three women, including two dark-skinned maids (Aibileen Clark and Minny Jackson). These characters tell about their experiences working for white masters in the early 1960s, in the city of Jackson, Mississippi, during a time of severe racial segregation. Newly arising after every release of such literary or film texts (just remember the recent film “Green book”), the ongoing controversy over cultural appropriation determines the relevance of addressing this topic. K. Stockett presents these characters as anti-racism fighters, with the word as their main weapon. Minny bluntly tells her employers what she thinks of them, which is in line with how African-American authors describe in their texts a way of speaking boldly to those you obey, called “to sass”. On the other hand, Aibileen tries not to show her attitude to white people and, in conversations with them, encodes the true content of her statements as much as possible, in fact using the practice of “signifying”, also characteristic of African-American culture: persuading other maids to tell a white girl about the relationship between masters and servants in their city, in order for it to be published. She deems the written preservation of an ethnic group history as a way to fight against racism. The author comes to the conclusion that K. Stockett follows, consciously or not, the traditions of African-American literature, in which many dark-skinned characters appear as tricksters.
Predicting Partition Coefficients of Short-Chain Chlorinated Paraffin Congeners by Combining COSMO-RS and Fragment Contribution Model Approaches
Authors: Endo Satoshi , Hammer Jort
Published: August 2020

Chlorinated paraffins (CPs) are highly complex mixtures of polychlorinated n-alkanes with differing chain lengths and chlorination patterns. Knowledge on physicochemical properties of individual congeners is limited but needed to understand their environmental fate and potential risks. This work combines a sophisticated but time-demanding quantum chemically based method COSMO-RS and a fast-running fragment contribution approach to establish models to predict partition coefficients of a large number of short-chain chlorinated paraffin (SCCP) congeners. Molecular fragments of a length of up to C4 in CP molecules were counted and used as explanatory variables to develop linear regression models for predicting COSMO-RS-calculated values. The resulting models can quickly provide COSMO-RS predictions for octanol–water (Kow), air–water (Kaw), and octanol–air (Koa) partition coefficients of SCCP congeners with an accuracy of 0.1–0.3 log units root mean squared errors (RMSE). The model predictions for Kow agree with experimental values for individual constitutional isomers within 1 log unit. The ranges of partition coefficients for each SCCP congener group were computed, which successfully reproduced experimental log Kow ranges of industrial CP mixtures. As an application of the developed approach, the predicted Kaw and Koa were plotted to evaluate the bioaccumulation potential of each SCCP congener group.

Diabetes is considered as one of the main comorbidities linked to the severity of respiratory syndrome coronavirus 2. For people living with diabetes, even a minor illness can lead to dangerously high blood sugar levels. This may cause life-threatening complications, such as diabetic ketoacidosis or a hyperosmolar hyperglycaemic state. Literature has been found that 20–50% affected patients of COVID-19 pandemic are diabetic. Diabetic patients are highly affected due to increased viral entry into the cell, decrease immunity. Here are several hypotheses to explain the increased incidence and severity of COVID-19 infection in people with diabetes. Several cytokines are liberated in diabetics which can play a more deleterious role in Covid-19 infection. The severe acute respiratory syndrome (SARS)-CoV2, coronavirus pandemic highlights the importance of understanding shared disease pathophysiology, potentially informing therapeutic choices in individuals with Type 2 diabetes. Thus, knowledge about the potential mechanisms in between diabetes & the novel coronavirus is of utmost importance To managed diabetes, and individuals need to face challenges in the current trends in this pandemic crisis. For oral health professional, the management of diabetes should follow the protocol for the treatment of individuals with diabetes. This review illustrates the mechanisms by which diabetes modulates the host-viral interaction, host-immune responses and guidelines to manage during an illness.

Coronavirus disease in 2019, also called COVID-19, which has been widely spread worldwide had given rise to a pandemic situation. The public health emergency of international concern declares the agent as the (SARS-CoV-2) the severe acute respiratory syndrome coronavirus 2. The COVID-19 pandemic has an unusual way of stroking the entire world. Crises have spread rapidly, disease load and casualties are still on the rise, and crisis influence is spreading across developing countries. Around the globe, the reactions, perceptions, and outcomes were distinct. The outbreak has reflected unfavourable mental health impacts and symptoms. This pandemic has also affected the healthcare department that is treating the patients suffering from diseases other than corona. The power and severity of slowdown varying from being temporary to a long-term recession, they are unanimous about the fact that the slowdown would have an intense impact amongst various sectors of the economy. Most importantly, some panic among consumers and firms has disfigured standard patterns of consumption and caused market inconsistency. This article would give the overall idea of how the social, economic, cultural, and psychological aspects influenced by the pandemic.
