Reliability of coeliac and superior mesenteric artery origin level in lumbosacral transitional vertebrae detection and vertebral numbering
Authors: BIYIKLI Erhan , SEVER Ibrahim Halil , BALTACIOGLU Feyyaz
Published: November 2021

Objective: To evaluate the value of coeliac artery (CA) and superior mesenteric artery (SMA) origin levels as an anatomic marker in the detection of lumbosacral transitional vertebrae (LSTV) and vertebral enumeration.
Patients and Methods: Institutional review board approval was obtained. Routine lumbar magnetic resonance (MR) imaging that included sagittal cervicothoracic scout images in 972 cases were evaluated retrospectively. Six segments were created in the vertebral column with 7 lines. CA and SMA ostiums were localized in these segments.
Results: Coeliac artery and SMA levels were detected more caudally in lumbarized S1 and more cranially in sacralized L5 cases compared to non-LSTV cases.
Conclusion: Coeliac artery and SMA origin levels are not confidential in consequence of wide variability.
An Assessment of Progress in the Implementation of the BWM Convention on Ships as an Important Element in Protecting Aquatic Ecosystems
Authors: Zatoń-Sieczka Kinga , Czerniejewski Przemysław
Published: November 2021

The purpose of this study was to assess progress in the implementation of rules for the control and handling of ballast water and sediments, regulated by the International Convention on the Control and Handling of Ship Ballast Water and Sediments (BWM Convention). The survey was conducted in 2018-2019 among seafarers responsible for handling ballast tanks. Analysis of the survey data revealed that despite the introduction of water treatments, ballast water continues to be a vector for the transfer of non-native organisms. This is due to the low effectiveness of the methods used, and the fact that 8% of the respondents answered that no BWT systems were used on the ships they manage. Despite this, some seafarers (4.7%) indicated that increasing environmental awareness and adherence to BWM principles should result in improved protection of aquatic ecosystems. Therefore, the global problem concerning the transport of non-native organisms via ballast water has still not been solved effectively. In the near future, improved BWT systems should be introduced, which after proper training of the crew will act as a barrier to the transfer of non-native organisms in ballast water.
Gas Formation Reactions in the Raw Mixture Based on TPP Ash
Authors: Koshlak Hanna
Published: November 2021

The article discusses the physicochemical mechanisms of the effect of chemical reagents on the processes of swelling of the raw mixture based on the ash of thermal power plants. The process of structure formation in such mixtures occurs as a result of physicochemical transformations of its constituent components. To intensify gas evolution and obtain materials of a porous structure, the presence of a gas former is necessary. The author has analysed the possibility of creating a porous structure in a raw mixture based on ash with the introduction of various gas formers or their formation as a result of exchange reactions. The main chemical compounds contributing to pore formation have been determined. To form a given structure, it is proposed to control chemical transformations at the stage of swelling. To study the processes of intensification of gas evolution, the author proposes to investigate the mechanisms of the influence of mineral fillers and chemical reagents on swelling processes based on the analysis of the Gibbs equation. The parameters of the Gibbs equation are obtained, by which it is possible to determine the probability of the occurrence of chemical reactions with the proposed chemical agents for the formation of gas bubbles with (pores) in the raw material.

Published: November 2021

Estimating the amount of suspended sediment in rivers correctly is important due to the adverse impacts encountered during the design and maintenance of hydraulic structures such as dams, regulators, water channels and bridges. The sediment concentration and discharge currents have usually complex relationship, especially on long term scales, which can lead to high uncertainties in load estimates for certain components. In this paper, with several data-driven methods, including two types of perceptron support vector machines with radial basis function kernel (SVM-RBF), and poly kernel learning algorithms (SVM-PK), Library SVM (LibSVM), adaptive neuro-fuzzy (NF) and statistical approaches such as sediment rating curves (SRC), multi linear regression (MLR) are used for forecasting daily suspended sediment concentration from daily temperature of water and streamflow in the river. Daily data are measured at Augusta station by the US Geological Survey. 15 different input combinations (1 to 15) were used for SVM-PK, SVM-RBF, LibSVM, NF and MLR model studies. All approaches are compared to each other according to three statistical criteria; mean absolute errors (MAE), root mean square errors (RMSE) and correlation coefficient (R). Of the applied linear and nonlinear methods, LibSVM and NF have good results, but LibSVM generates a slightly better fit under whole daily sediment values.
The Influence of the Przebędowo Reservoir on the Water Quality of the Trojanka River in the First Years of its Functioning
Authors: Waligórski Błażej , Janicka Ewelina
Published: November 2021

Agriculture, mainly biogenic compounds (nitrogen and phosphorus) and plant protection products are one of the sources of environmental pollution. The sources of pollution are both farm buildings and intensively used agricultural land. Therefore, a crucial element of the environment contributing to the improvement of surface water quality are the aforementioned shallow reservoirs covered by vegetation that act as biofiltres or reservoirs such as dammed reservoirs. The analysed reservoir is located in the Greater Poland Province, about 25 km to the north from Poznań, in Murowana Goślina commune. The research on the analysed reservoir was conducted during the growing seasons, from 2016 to 2018, at three measurement and control points: at the Przebędowo reservoir inflow, it the Przebędowo reservoir and at the Przebędowo reservoir outflow. They included determining 4 groups of physico-chemical indicators supporting biological elements, including indicators characterising aerobic conditions, salinity, acidification (pH) and indicators characterising biogenic conditions. Based on the conducted research, a great influence of the reservoir was proven, especially in the context of the concentration of dissolved oxygen at the outflow, where, concerning this indicator, the reservoir was classified as water quality class I. The presented research results also confirmed that in the context of the complexity of hydrological and physico-chemical processes taking place in dammed reservoirs, it is necessary to continuously control them both in terms of water quantity and quality.

In the paper there is presented an evaluation of variability of surface water quality (reservoirs and watercourses), on the area of degraded post-mining area in Bytom. The physicochemical analysis of water and compared with archival data obtained in 2009 and 2014. There were done analysis of following parameters: reaction, total content of substances dissolved in water, water hardness and the content of: Cl-, SO42-, HCO3-, Ca2+, Mg2+, K+, Na+, NH4+, NO3-, NO2-, PO4- ions as well as Fe and Mn. The examined surface waters were characterised by high content of solutes. Anions were dominated by chlorides, the sodium proved to be the dominating cation, the examined water samples were characterised by high concentration of sulphates. In all analyzed reservoirs, permissible concentrations of chlorides and sulphates were exceeded. In all sample points there was observed a decrease of pH value in long term period, the concentration of chlorides lowered, however concentrations of sulphates increased in the majority of sampling points.

Published: November 2021

The problem of municipal waste management is one of the greatest challenges of the 21st century. Its solution requires the integrated involvement of central and local authorities as well as the public. For their actions to be fully effective, they must be accompanied by an increase in environmental awareness. The aim of the study was to assess the environmental awareness and knowledge of inhabitants of eastern Mazovia regarding municipal waste management. A survey study was carried out on a group of 262 individuals using a questionnaire. Analysis of the results showed that the surveyed inhabitants of eastern Mazovia were aware of problems associated with municipal waste management, but some of them were critical of the actions taken by central and municipal authorities to solve them. Their high level of environmental awareness and knowledge was evidenced by the fact that most of those surveyed were familiar with the principles of selective collection of municipal waste, including green and hazardous waste.

Published: November 2021

Electrical energy is a primary need at this time, which almost all human activities require electricity. The electrical energy we use today is a conversion from other energy, partly derived from fossil energy, which is energy that cannot be renewed and will run out if it is continuously explored and exploited. Solar energy is a renewable energy source that has the potential to be converted to electrical energy using solar panels or so-called photovoltaics.

Photovoltaic has a drawback in its use, namely the output value is very dependent on environmental conditions. To maximize the power efficiency between the photovoltaic output and the power to be used by the load, a method is needed, namely Maximum Power Point Tracking (MPPT). In the application of this MPPT DC-DC Zeta converter is used with a hill climbing algorithm to achieve the value of the output voltage and current at maximum power. With this method, it is expected that MPPT control is reliable and easy to apply.

In this study, the type of photovoltaic module used is the 60 Wp monocrystalline type with sampling data once an hour from 09.00 - 17.00 WITA, the tracking speed data obtained by the modified hill climbing algorithm is 0.142 seconds on average with an average efficiency of 99.969 %.

Analytical Model for the Prediction of Performance of a Solar Driven Diffusion Absorption Cooling System
Authors: GUREVİCH Bella , ZOHAR Amir
Published: November 2021

In contrast to standard vapor compression cooling systems, diffusion absorption refrigeration (DAR) systems are heat-driven and contain no moving parts. Solar diffusion absorption cooling systems can extract heat from a cooling chamber without electricity, enabling food and medicine to be cooled in remote places where there is high solar radiation with unavailable or unreliable electricity. This work aims to model the performance of a solar-driven DAR system with an evacuated tubes collector. The model inputs were the local hourly ambient temperature and solar irradiance for the time of June to August in Ashdod, Israel. Also, collector data, ammonia concentration in the solution, evaporator temperature and the DAR system geometry were considered. The model results showed that as the generator heat input increased rapidly the evaporator cooling capacity was kept almost constant for a given concentration and collector area. This resulted in reduction in the COP values at peak hour. An increase in the collector area had more impact on the heat applied to the generator and not resulted in a significant growth of the cooling capacity, thus, the authors concluded that for optimal COP it is advised to operate the system with lower collector areas.
An Advanced Platform for Thermodynamics Education. Part two: Monomer Quantum Volume in Pure Fluides
Authors: SEDUNOV Boris
Published: November 2021

The paper presents a remarkable application of the advanced thermodynamics education platform to the molar Gibbs energy G for basic particles in neat fluids. From the G, named also as the chemical potential, and the monomer fraction density Dm functions the Monomer Quantum Volume Vq (T) may be computed. The Vq (T) variable reflects the quantum uncertainty of basic particles positions in atomic and molecular fluids. It has proven to be universal for all fluid’s densities at a fixed temperature T. An extraordinary precision of modern thermophysical databases, such as the NIST Webbook, permits an estimation of the Monomer Quantum Volume values millions times lower than the atom’s volume! By studying the Vq (T) function the students can estimate the quantum uncertainty effects in pure fluids for a total range of their existence up to thousands of Kelvin! The enthalpy data normalization has proven to be very efficient. The advanced platform is highly useful and informative for thermodynamics education. For students it is very educative to study and utilize the author’s computer aided big thermophysical data analysis method to form their vision of the atomic and molecular quantum states distribution in pure fluids.
La filosofia com a ciència teòrica: la proposta de Timothy Williamson
Authors: Pau Manel
Published: November 2021

Timothy Williamson defensa que la filosofia és una ciència teòrica que s’ocupa d’investigar sobre la realitat, d’obtenir coneixement, i que ho fa construint teories, confrontant-les amb l’evidència, d’una manera sistemàtica, disciplinada i socialment organitzada, com les altres ciències. En aquest article es compara aquesta posició, d’una banda, amb la que considera que la filosofia és una reflexió de segon ordre sobre la ciència, la moral, la política, l’art…; i, de l’altra, amb la concepció de la filosofia com a guia de la vida, com a recerca de la saviesa pràctica.
Community mental health work – WHO recommendations and the perspective of people experiencing mental health problems
Authors: Jarkiewicz Anna , Granosik Mariusz
Published: November 2021

This article was written in response to the publication by the World Health Organization of a document containing recommendations and a toolkit for promoting mental health and addressing the problems of people with mental disorders (Mental Health Gap Action Programme – mhGAP). The conclusions in the WHO proposal were compared with the perspective of people in mental crisis, which was reconstructed through qualitative research (in the interpretative paradigm). The analysis of the empirical material, which consisted of 35 autobiographical narrative interviews with people who have experienced mental disorders, showed that the WHO proposals correspond to the needs declared by the people struggling with mental problems. The compliance concerns both the expected fields of action (fight against stereotypes, prevention, health promotion) and methods (activities in the residential environment of people in need of support). At the same time, however, the analysis revealed a number of elements worth noting when orienting future community mental health work. These elements include: the increasing role and importance of people experiencing mental disorders in the orientation of action, strengthening community co-creation with people experiencing a mental disorder, moving away from one-sided teaching and training towards collaborative learning.
Glucocorticoid therapy in assisted reproduction
Authors: Kim Yong Jin
Published: November 2021

As glucocorticoids are well-known as important regulators of stress and the immune system, their function and clinical use have elicited substantial interest in the field of reproduction. In particular, the effect of glucocorticoid therapy on endometrial receptivity during assisted reproduction, including in vitro fertilization (IVF) cycles, has led to a great deal of interest and controversy. However, previous studies have not been able to provide consistent and reliable evidence due to their small, non-controlled designs and use of different criteria. Considering the potential risk of exposure to glucocorticoids for mothers and fetuses in early pregnancy, the use of glucocorticoids in IVF cycles should be carefully evaluated, including the balance between risk and benefit. To date, there is no conclusive evidence that the use of glucocorticoids improves the pregnancy rate in IVF cycles with unselected subjects, and a further investigation should be considered with a proper study design.

Published: November 2021

The mid-nineteenth century saw extensive diaspora from Europe to the antipodes. New Zealand in particular was marketed to the poor and middle classes of the United Kingdom (UK) as a “Better Britain”; a pastoral utopia of abundant resources and easy living. These campaigns actively targeted young, able-bodied persons with the aim of creating a thriving and productive colony. The rural community of Milton, Otago, in the South Island, was a farming settlement established predominantly by immigrants from the UK. The University of Otago undertook an excavation at St. John’s Anglican burial ground (SJM) in 2016 with the aim of reconstructing some aspects of the lives of these nineteenth-century European (Pākehā) settlers. One of the 27 individuals recovered, burial 29, was an adult female with a striking thoracic deformity and several other features suggestive of a skeletal growth disorder. Here, we combine multiple lines of bioarchaeological evidence to create an osteobiographyof this individual and discuss the implications of our findings for conceptions of disability, status, personhood, and social value in Victorian frontier society.

Earth Politics of the Spiritual Ground
Authors: Taylor Mark Lewis ,   Caribbean Philosophical Association
Published: November 2021

Amid the coloniality of power, earth politics is a political spirituality. It fosters decolonizing practices that create what Colombian anthropologist Albán Achinte terms “re-existence”—a “redefining and re-signifying of life in conditions of dignity.” Earth politics’ spirituality can be read across the writings of Gloria Anzaldúa, Drucilla Cornell/Stephen Seely, and Paget Henry. Earth politics, in Henry’s words, is a “drama of consciousness” with a “spiritual ground,” a consciousness that is both “vertical” and “horizontal”—better, a spherical and ambient consciousness “grounding” an earthy awareness that is historical and poetic, local and planetary. Earth politics infused with such consciousness can become a force against even imperio-colonial practices of torture against colonized peoples. U.S. activist Sister Dianna Ortiz, embodies this counter-force of earth politics in her “life after torture,” in her collective struggle against the neo-imperialist torture-state that is the United States.

Not toeing the number line for simple arithmetic: Two large-n conceptual replications of Mathieu et al. (Cognition, 2016, Experiment 1)
Authors: Campbell Jamie I. D. , Chen Yalin , Azhar Maham
Published: November 2021

We conducted two conceptual replications of Experiment 1 in Mathieu, Gourjon, Couderc, Thevenot, and Prado (2016, https://doi.org/10.1016/j.cognition.2015.10.002). They tested a sample of 34 French adults on mixed-operation blocks of single-digit addition (4 + 3) and subtraction (4 – 3) with the three problem elements (O1, +/-, O2) presented sequentially. Addition was 34 ms faster if O2 appeared 300 ms after the operation sign and displaced 5° to the right of central fixation, whereas subtraction was 19 ms faster when O2 was displaced to the left. Replication Experiment 1 (n = 74 recruited at the University of Saskatchewan) used the same non-zero addition and subtraction problems and trial event sequence as Mathieu et al., but participants completed blocks of pure addition and pure subtraction followed by the mixed-operation condition used by Mathieu et al. Addition RT showed a 32 ms advantage with O2 shifted rightward relative to leftward but only in mixed-operation blocks. There was no effect of O2 position on subtraction RT. Experiment 2 (n = 74) was the same except mixed-operation blocks occurred before the pure-operation blocks. There was an overall 13 ms advantage with O2 shifted right relative to leftward but no interaction with operation or with mixture (i.e., pure vs mixed operations). Nonetheless, the rightward RT advantage was statistically significant for both addition and subtraction only in mixed-operation blocks. Taken together with the robust effects of mixture in Experiment 1, the results suggest that O2 position effects in this paradigm might reflect task specific demands associated with mixed operations.
When does the story matter? No evidence for the foregrounding hypothesis in math story problems
Authors: Di Lonardo Burr Sabrina M. , Turner Jill , Nietmann Jesse , LeFevre Jo-Anne
Published: November 2021

Math story problems are difficult for many solvers because comprehension of mathematical and linguistic content must occur simultaneously. Across two studies, we attempted to conceptually replicate and extend findings reported by Mattarella-Micke and Beilock (2010, https://doi.org/10.3758/PBR.17.1.106) and Jarosz and Jaeger (2019, https://doi.org/10.1002/acp.3471). Mattarella-Micke and Beilock found that multiplication word problems in which an irrelevant number was associated with the protagonist of the problem (i.e., foregrounded in the text) were solved less accurately than problems in other conditions. Jarosz and Jaeger used similar materials but tested the more general inconsistent-operations hypothesis that association with the protagonist would interfere with multiplication whereas dissociation would interfere with division. They found partial support: When division problems were primed with dissociative scenarios, solvers made more errors, but they failed to replicate the associative findings for multiplication. In the present research, we conducted two studies (Ns = 205 and 359), in which we similarly manipulated whether irrelevant content was associated with or dissociated from the story protagonist. In these studies, we did not find support for either the foregrounding or inconsistent-operations hypotheses. Exploratory error analyses suggested that solvers’ errors were most often the result of calculation difficulties or inappropriate operation choices and were unrelated to the presence of associative or dissociative story elements. Our careful implementation of this manipulation and much greater power to detect effects suggests that the association manipulation in irrelevant text does not influence adults’ performance on simple math story problems.
Making sense of the relation between number sense and math

Published: November 2021

While several studies have shown that the performance on numerosity comparison tasks is related to individual differences in math abilities, others have failed to find such a link. These inconsistencies could be due to variations in which math was assessed, different stimulus generation protocols for the numerosity comparison task, or differences in inhibitory control. This within-subject study is a conceptual replication tapping into the relation between numerosity comparison, math, and inhibition in adults (N = 122). Three aspects of math ability were measured using standardized assessments: Arithmetic fluency, calculation, and applied problem solving skills. Participants’ inhibitory skills were measured using Stroop and Go/No-Go tasks with numerical and non-numerical stimuli. Finally, non-symbolic number sense was measured using two different versions of a numerosity comparison task that differed in the stimulus generation protocols (Panamath; Halberda, Mazzocco & Feigenson, 2008, https://doi.org/10.1038/nature07246; G&R, Gebuis & Reynvoet, 2011, https://doi.org/10.3758/s13428-011-0097-5). We find that performance on the Panamath task, but not the G&R task, related to measures of calculation and applied problem solving but not arithmetic fluency, even when controlling for inhibitory control. One possible explanation is that depending on the characteristics of the stimuli in the numerosity comparison task, the reliance on numerical and non-numerical information may vary and only when performance relies more on numerical representations, a relation with math achievement is found. Our findings help to explain prior mixed findings regarding the link between non-symbolic number sense and math and highlight the need to carefully consider variations in numerosity comparison tasks and math measures.

The goal of the current study was to conduct a conceptual replication of the reciprocal associations between executive function (EF) and academic achievement reported in Schmitt et al. (2017, https://doi.org/10.1037/edu0000193). Using two independent samples (N (STAR) = 279, and N (Pathways) = 277), we examined whether the patterns of associations between EF and achievement across preschool and kindergarten reported in Schmitt et al. (2017) replicated using the same model specifications, similar EF and achievement measures, and across a similar developmental age period. Consistent with original findings, EF predicted subsequent math achievement in both samples. Specifically, in the STAR sample, EF predicted math achievement from preschool to kindergarten, and kindergarten to first grade. In the Pathways sample, EF at kindergarten predicted both math and literacy achievement in first grade. However, contrary to the original findings, we were unable to replicate the bidirectional associations between math achievement and EF in either of the replication samples. Overall, the current conceptual replication has revealed that bidirectional associations between EF and academic skills might not be robust to slight differences in EF measures and number of measurement occasions, which has implications for our understanding of the development EF and academic skills across early childhood. The present findings underscore the need for more standardization in both measurement and modeling approaches – without which the inconsistency of findings in published studies may continue across this area of research.

Neste artigo, analisamos a constituição de uma memória coletiva a partir da contribuição de obras consagradas como fundamentais para a compreensão da trajetória do teatro pernambucano. As obras selecionadas foram: O teatro moderno em Pernambuco, de Joel Pontes; O teatro em Pernambuco, de Alexandre Figueirôa; Por um teatro do povo e da terra, de Luís Maurício Carvalheira e TAP – sua cena e sua sombra, de Antonio Cadengue. Com a análise desses textos, procuramos mostrar de que forma algumas teses sobre o teatro pernambucano foram se consolidando pela regularidade com que foram enunciadas ao longo de cinco décadas. Essas teses foram enquadradas numa narrativa consagrada, através da qual diferentes sujeitos e grupos de teatro foram nomeados e desafiados a comprovarem uma função específica na memória organizadora constituída por essa narrativa, sob pena de caírem no esquecimento por falta de relevância. Neste sentido, a constituição de uma memória coletiva, como estudamos aqui, não tem como tema principal uma correspondência entre os discursos analisados e o “real”, mas a coerência interna de uma narrativa consagrada e suas ideias sobre o teatro pernambucano.

Retroperitoneal Liposarcoma: An Unusual Presentation of a Rare Cancer
Authors: L. Spicer, MA, PA-C Jennifer
Published: November 2021

Retroperitoneal liposarcomas (RLPS) are rare tumors that have variable clinical behavior and complex treatment strategies based on presentation, histopathology, and genomics. Early identification is critical, and complete surgical resection remains the primary treatment, although chemotherapy and radiation are used on individual bases. Presenting symptoms are often nonspecific; therefore, a high degree of suspicion is essential for early diagnosis. In this report, the management of a 37-year-old otherwise healthy male with a large RLPS causing right groin/testicular pain is presented. After three evaluations in the emergency department, the patient was diagnosed and received two cycles of doxorubicin/ifosfamide/mesna (AIM) neoadjuvant chemotherapy. His physical exam on presentation for second opinion demonstrated a large palpable abdominal mass and fullness around the right spermatic cord. There was no appreciable change in tumor size or distant metastases on repeat scanning. Given some obstructive symptoms, a multidisciplinary team advised neoadjuvant radiation followed by radical resection of RLPS. Final pathology demonstrated a 31-cm grade II well-differentiated (WD) liposarcoma with low-grade dedifferentiation. Scattered foci of microscopic positive WD margins were noted, and the remainder of margins were negative. Genomic evaluation showed amplification of CDK4, MDM2, and FRS2. A concise literature review of common presentations, histopathology, genomics, and treatment information is discussed herein. Thorough physical exams, attention to subtle findings, appropriate medical imaging studies, and a high index of suspicion when evaluating vague symptomatology can lead to earlier diagnosis and treatment of RLPS, and ultimately better patient outcomes.

La crisis del coronavirus ha resaltado el poder de lo local y de la proximidad en la construcción de respuestas a la mitigación y expansión del virus. Las entidades locales han desarrollado respuestas tanto individuales como colectivas para hacer frente a la pluralidad de necesidades ciudadanas originadas tras la aparición del virus y la declaración del estado de alarma por el gobierno de España.
En este sentido, es objeto del presente artículo analizar las iniciativas solidarias implementadas desde las entidades locales de la provincia de Valencia en aras de ejemplificar el papel protagónico de dichas entidades locales durante la crisis del COVID-19. Ante las recomendaciones y restricciones sanitarias, se ha considerado conveniente optar por la selección de la metodología cuantitativa y en base a ella, se ha empleado la técnica de la encuesta autoadministrada. Gracias a la selección de esta técnica, se ha logrado una alta tasa de respuesta, logrando alcanzar un total de noventa respuestas por parte de las entidades locales.
Entre los resultados principales, cabe destacar que las iniciativas solidarias desarrolladas por parte de las entidades locales han estado orientadas tanto a la satisfacción de las necesidades básicas como a la mitigación de las consecuencias sociales, económicas y sanitarias del coronavirus. En conclusión, los ayuntamientos han constituido el primer bastión en la lucha contra el coronavirus, adoptando nuevos roles desde su posicionamiento estratégico a las necesidades de la ciudadanía. Asimismo, la pluralidad de iniciativas solidarias desarrolladas alude indirectamente a la capacidad adaptativa de la administración local a la diversidad de situaciones carenciales que han tenido lugar a raíz de la crisis del coronavirus.

Background

Young individuals with visual impairment (VI), exposed to higher risky of social exclusion, might be more prone to Internet risky behaviours including electronic aggression.

Objective

Different types of Internet risky behaviours and the average time spent online were investigated among students with VI. These behaviours were analyzed for the relationship with witnessing, perpetrating and becoming a victim of electronic aggression.

Methods

A total of 490 special needs school students with VI answered a self-administered questionnaire. The average time spent online, different types of risky Internet activities and electronic aggression were recorded, as well as sociodemographic characteristics.

Results

Male students downloaded software illegally, hacked, published and viewed sites with sexual content, and gambled online statistically more often than female counterparts. Concerning electronic aggression, more than half of participants were engaged as witnesses, every fifth student as a victim and 11.6% as perpetrators. Two sets of ordinal logistic regression analyses have shown that communication with a person promoting violence and an excessive amount of time spent online during weekends predicted significantly the risk of witnessing and being a victim of electronic aggression. Additionally, communicating with a person promoting violence and an excessive amount of time spent online during schooldays were associated with increased odds for engagement in electronic aggression as a perpetrator.

Conclusions

Population with VI is prone to risky Internet use and likely to be engaged in electronic aggression. New instruments and preventive strategies need to be developed, as well as diagnostic tools tailored specifically to the needs of young people with VI.
Staphylococcal Epidermolysis: A Case Report

Published: November 2021

Acute staphylococcal epidermolysis, also known as staphylococcal scalded skin syndrome (SSSS), in young children is caused by the release of exfoliative toxins A and B (ETA and/or ETB) from an initial outbreak which can be ear-nose-throat, conjunctival or cutaneous.

Staphylococcal scalded skin syndrome is characterized by painful erythroderma, quickly followed by generalized detachment with respect to mucous surfaces, regressing in 2 to 4 days on antibiotics. The positive diagnosis is mainly based on clinical examination and sometimes on skin biopsy.

The course of the disease is benign, favored by anti-staphylococcal treatment combined with local care. However, the risk of fatal course is estimated at around 4% in the event of delay in antibiotic treatment. We report the case of an infant with SSSS, diagnosed and treated early with good evolution.

Nitrofurantoin (NT) used for the treatment of urinary tract infections may have antiplasmodial activity. Dihydroartemisinin-piperaquine (DP) is an artemisinin based combination therapy used for the treatment of malaria. This study evaluated the antiplasmodial effect of dihydroartemisinin-piperaquine-nitrofurantoin (DP-NT) on mice infected with Plasmodium berghei. Adult Swiss albino mice (30-35 g) of both sexes were used. The mice were randomly grouped, inoculated with Plasmodium berghei, and treated orally with DP (1.7/13.7 mg/kg), NT (57.1 mg/kg) and DP-NT (1.71/13.7/ 57.1 mg/kg), respectively using curative, prophylactic and suppressive tests. The negative control was orally treated with normal saline (0.3 mL), while the positive control was orally treated with chloroquine CQ (10mg/kg). After treatment, blood samples were collected and evaluated for percentage parasitemia, inhibitions and hematological parameters. Liver samples were evaluated for histological changes. The mice were observed for mean survival time (MST). Treatment with DP-NT decreased parasitemia levels when compared to individual doses of DP and NT with significant difference observed at p<0.05. DP-NT prolonged MST when compared to individual doses of DP and NT with significant difference observed at p<0.05. The decrease in packed cell volume, red blood cells, hemoglobin and increase in white blood cells in parasitized mice were significantly restored by DP-NT  when compared to individual doses of DP and NT with difference observed at p<0.05. DP-NT eradicated liver Plasmodium parasite.  NT remarkably increased the antiplasmodial activity of DP. DP-NT may be used for the treatment of malaria.

Deltamethrin and piperonyl butoxide two synthetic pyrethroids, when used in a combination it produces synergistic effect. This two insecticide has found to be widely used in the management of mosquito, housefly and other insects to control the various vector born diseases. In this review we assessed the toxic effect of deltamethrin and piperonyl butoxide on beneficial organisms commonly available in the ecosystem. It was found to be toxic to fish, honey bees the prime pollinators of crop plant; earthworm is also susceptible at a lethal concentration for a particular exposure. As far the birds are concerned, they have a less toxic risk in lower concentration of exposure. The alterations obtained in the hematological, biochemical and histopathological studies, further conclude that it can cause environment hazards and toxic to the non-targeted organisms. This investigation gives an insight into the combined toxicological profile of deltamethrin and PBO for better risk assessment and safe use of pyrethroids and their synergist in non-targeted organisms.

Yellow fever is a neglected hemorrhagic disease with a high case fatality rate ranging between 25% and 50% for the hospitalized patients. Yellow fever disease is caused by a zoonotic pathogen known as yellow fever virus. This RNA virus is usually transmitted by mosquitos and it is considered endemic in the tropical regions of South America and Africa. Although an effective vaccine is available for yellow fever virus, no antiviral drug is yet licensed against the disease. Thus, yellow fever virus is still representing a re-emerging threat among unvaccinated individuals in endemic regions. The NS2B-NS3 protease seems to play an important role in yellow fever virus replication cycle. As such, the NS2B-NS3 protease may represent a potential target for structure-based drug design and discovery. In this direction, computational approaches like virtual screening can be utilized to hasten the design of novel antivirals and/ or repurposing an already FDA approved drugs. In this in silico study, an FDA approved drugs library was screened against NS2B-NS3 protease crystal of yellow fever virus. Then the best hits with least energy of binding and ability of hydrogen bonding with key residues of protease active site were then selected and submitted to molecular dynamics simulation. And throughout simulation interval, only Olsalazine was able to stay in close proximity to the active site of protease crystal with least average MM-PBSA binding energy as compared to Dantrolene, Belinostat and Linezolid. This indicates that Olsalazine may have the best capacity to bind to NS2B-NS3 protease and interfere with its activity.
