Authors: Chandio Mansoor , Shafiq Faraz , Enam Ather
Published: April 2021

Objective: The postoperative period is critical in neurosurgical patients, where the incidence of postoperative AEs is significantly high. Most of events occurs during recovery phase and has got relation to anaesthetic management. The objective of study was to determine frequency of early AEs in elective neurosurgical patients.

Methods: This cross sectional study was conducted at our tertiary care center. The duration of study was one year, from August 2017-July 2018. The data was collected using predesigned proforma. The assessment was done on arrival in recovery room (T1) and then at forty five minutes (T2), twenty-fourth hour (T3) and forty-eighth hour (T4) postoperatively.

Results: Total ninety-five patients were included. Overall, five hundred and forty AEs were recorded at T1, T2, T3 and T4. Anaesthesia related events like pain, postoperative sore throat, hoarseness, shivering and hypothermia were the commonest (73%). There was a gradual decline in incidence of these events over period of 48 hours. There was no effect of age, sex, BMI and blood loss on incidence of AEs.

Conclusions: Postoperative pain, PONV and shivering were frequently reported AEs. We did not identify the impact of age, sex, BMI, comorbid or type of surgery in terms of having these events.

Diagnostic, management and nursing challenges of less common dementias: Parkinsonian dementias and Huntington's disease
Authors: Davis Laura , Dening Tom
Published: April 2021

Background:

Although most cases of dementia are caused by Alzheimer's disease or vascular dementia, around 10-15% of cases are due to other disorders, including dementias with Parkinsonian features, Huntington's disease, frontotemporal dementia, human immunodeficiency virus (HIV), and alcohol.

Aims:

These less common dementias are important as they may have differing clinical features and require different approaches to diagnosis and management. This paper seeks to provide relevant information for nurses about symptoms, diagnosis and management of some of the less common dementias.

Methods:

This is one of two connected papers, and provides a clinical overview of Parkinsonian dementias and Huntington's disease. It provides a narrative, rather than systematic, review of the literature.

Findings:

Parkinsonian dementias comprise Parkinson's disease dementia, dementia with Lewy bodies and so-called Parkinson's-plus syndromes (multi-system atrophy, progressive supranuclear palsy, and corticobasal degeneration). Huntington's disease is an inherited neuropsychiatric condition. Each has a distinctive clinical picture, with combinations of cognitive, neuropsychiatric and neurological symptoms but approaches to treatment and care are essentially supportive.

Conclusions:

Nurses have an essential role in supporting people with dementia, as well their families and carers, throughout the course of dementia from diagnosis to end of life care. They are often best placed and have the necessary skills to create appropriate care plans and to provide care management.

The ectomycorrhizal community of urban linden trees in Gdańsk, Poland
Authors: Olchowik Jacek , Suchocka Marzena , Jankowski Paweł , Malewski Tadeusz , Hilszczańska Dorota
Published: April 2021

The linden tree (Tilia spp.) is a popular tree for landscaping and urban environments in central and northwest European countries, and it is one of the most popular in cities in Poland. Ectomycorrhizal fungi form a symbiosis with many urban tree species and protect the host plant from heavy metals and against salinity. The aim of this study was to characterise the ECM fungal community of urban linden trees along the tree damage gradient. The study was performed on two sites located in the centre of the city of Gdańsk, in northern Poland. The vitality assessment of urban linden trees was made according to Roloff’s classification. Tree damage classes were related to soil characteristics using principal component analysis. The five ectomycorrhizal fungal species were shared among all four tree damage classes, and Cenococcum geophilum was found to be the most abundant and frequent ectomycorrhizal fungal species in each class. Soil samples collected in the vicinity of trees belonging to the R0 class had significantly lower pH Na, Cl and Pb content than other soils. Our knowledge of ectomycorrhizal communities in urban areas is still limited, and these findings provide new insights into ectomycorrhizal distribution patterns in urban areas.
PharmaNet: Pharmaceutical discovery with deep recurrent neural networks
Authors: Ruiz Puentes Paola , Valderrama Natalia , González Cristina , Daza Laura , Muñoz-Camargo Carolina , Cruz Juan C. , Arbeláez Pablo
Published: April 2021

The discovery and development of novel pharmaceuticals is an area of active research mainly due to the large investments required and long payback times. As of 2016, the development of a novel drug candidate required up to $ USD 2.6 billion in investment for only 10% rate of approval by the FDA. To help decreasing the costs associated with the process, a number ofin silicoapproaches have been developed with relatively low success due to limited predicting performance. Here, we introduced a machine learning-based algorithm as an alternative for a more accurate search of new pharmacological candidates, which takes advantage of Recurrent Neural Networks (RNN) for active molecule prediction within large databases. Our approach, termed PharmaNet was implemented here to search for ligands against specific cell receptors within 102 targets of the DUD-E database, which contains 22886 active molecules. PharmaNet comprises three main phases. First, a SMILES representation of the molecule is converted into araw molecular image. Second, a convolutional encoder processes the data to obtain afingerprint molecular imagethat is finally analyzed by a Recurrent Neural Network (RNN). This approach enables precise predictions of the molecules’ target on the basis of the feature extraction, the sequence analysis and the relevant information filtered out throughout the process. Molecule Target prediction is a highly unbalanced detection problem and therefore, we propose that an adequate evaluation metric of performance is the area under the Normalized Average Precision (NAP) curve. PharmaNet largely surpasses the previous state-of-the-art method with 97.7% in the Receiver Operating Characteristic curve (ROC-AUC) and 65.5% in the NAP curve. We obtained a perfect performance for human farnesyl pyrophosphate synthase (FPPS), which is a potential target for antimicrobial and anticancer treatments. We decided to test PharmaNet for activity prediction against FPPS by searching in the CHEMBL data set. We obtained three (3) potential inhibitors that were further validated through both molecular docking andin silicotoxicity prediction. Most importantly, one of this candidates, CHEMBL2007613, was predicted as a potential antiviral due to its involvement on thePCDH17pathway, which has been reported to be related to viral infections.

Objectives

This study evaluates the effect of Community Anti-retroviral Groups on Immunologic, Virologic and clinical outcomes of stable Antiretroviral Therapy patients in Nigeria.

Method

A cohort of 251 eligible adults (≥18 years) on first-line ART for at least 6 months with CD4 counts >200 cells/mm3 and viral load <1000 c/ml were devolved from 10 healthcare facilities to 51 community antiretroviral therapy groups. Baseline immunologic, virologic and clinical parameters were collected and community antiretroviral therapy group patients were followed up for a year after which Human Immunodeficiency Virus treatment outcomes at the baseline and a year after follow-up were compared using paired sample t-test. All the analyses were performed in STATA version 14.

Result

Out of the 251 stable antiretroviral therapy adults enrolled, 186 (75.3%) were female, 52 (22.7%) had attained post-secondary education and the mean age of participants was 38 years (SD: 9.5). Also, 66 (27.9%) were employed while 125 (52.7%) were self-employed and 46(19.41%) unemployed. 246 (98.0%) of the participants were retained in care. While there was no statistically significant change in the CD4 counts (456cells/mm3 vs 481cells/mm3 P-0.489) and Log10viral load (3.54c/ml vs 3.69c/ml P-0.359) after one year of devolvement into the community, we observed a significant increase in body weight (60.8 vs 65, P-0.01).

Conclusion

This study demonstrates that community antiretroviral therapy has a potential of maintaining optimum treatment outcomes while improving adherence and retention, and reducing the burden of HIV treatment on the health facility. This study provides baseline information for further research and vital information for HIV program implementers planning to decentralize the management of stable antiretroviral therapy clients.
Do more stress and lower family economic status increase vulnerability to suicidal ideation? Evidence of a U-shaped relationship in a large cross-sectional sample of South Korean adolescents
Authors: Jeong Tay
Published: April 2021

It is widely held in socio-behavioral studies of suicide that higher levels of stress and lower levels of economic status amplify suicidal vulnerability when confronted with a proximal stressor, reflecting the traditionally prevalent understanding in health psychology and sociology that associates adverse life circumstances with undesirable mental health outcomes. However, upon reflection, there are strong theoretical reasons to doubt that having more stress or being in a more stressful environment always increases suicidal vulnerability given the occurrence of a crisis. Using large nationally representative public survey data on South Korean adolescents, I show that the association between recent psychosocial crisis and suicidal ideation often gets stronger with more favorable levels of perceived stress and improving levels of family economic status. Overall, the increase in the probability of suicidal ideation from recent exposure to a psychosocial crisis is consistently the smallest around medium levels of stress or family economic status and larger at low or high levels. A supplementary exercise suggests that the identified moderation effects operate mainly in virtue of individual-level stress or family economic status in the relative absence of contextual influences at the school level. The findings present preliminary evidence of the stress inoculation hypothesis with regard to suicidal ideation. Research on suicidal vulnerability could benefit from increased attentiveness to the mechanisms through which being in an adverse or unfavorable life situation could protect against the suicide-inducing effects of proximal stressors.
El naturalismo de Ronald Giere

Published: April 2021

Se presenta en este artículo el naturalismo de Ronald Giere, mostrando su base en las nociones de racionalidad limitada y de satisfacción de Herbert A. Simon. Se aduce a continuación que, pese al interés de su propuesta, la pretensión de Giere de hacer de la epistemología una rama de la psicología o de la biología es una reacción excesiva a los extremos aprioristas de la epistemología tradicional y del logicismo de los neopositivistas. Se concluye con algunas observaciones sobre su posición ante el tema de la verdad en la ciencia.

Published: April 2021

En (teoría de la) educación necesitamos abordar cuanto antes una pregunta: ¿Cómo hacer y pensar la educación en consonancia con las características, exigencias y oportunidades, de esta época digital? A este respecto, después de referenciar los derroteros que en este campo viene siguiendo la investigación pedagógica y la práctica educativa, se plantean en el cuerpo del artículo tres cuestiones – modos de ser, de experienciar el mundo y de construir conocimiento en un sujeto cuya relación con el entorno es mediada por una tecnología cuyo rasgo definitorio viene dado por una pantalla digital – que están demandando otra forma de ver la educación, dicho de otra manera, tres cuestiones directamente afectadas por el nuevo escenario creado por estas tecnologías y que una (teoría de la) educación de nuestro tiempo no puede ignorar, pues sería tanto como no (querer) ver la transición que se está produciendo en las formas de pensar y hacer educación; de alguna manera, sobre ellas descansa y pivota una (teoría de la) educación acorde con este nuestro tiempo digital.   El artículo termina con un elenco de preguntas de orden diverso, epistemológico, ontológico y metodológico, pero también ético y politico, estrechamente entrelazadas, que dejan entrever la conveniencia y necesidad de reorientar la reflexión en este campo, al tiempo que conforman un programa de investigación; preguntas con potencialidad suficiente para reorientar la investigación en (teoría de la) educación, inluido el propio concepto y sentido de educar y ser educado.
Concepciones sobre los sistemas de adquisición de datos en el trabajo de laboratorio en Física
Authors: Cardona-Zapata Mónica Eliana , Pabón-Rúa Daniel , López-Ríos Sonia Yaneth
Published: April 2021

Se ha reportado en la literatura especializada que en los trabajos prácticos de laboratorio en Física se presenta una clara escisión entre teoría y práctica que da cuenta de una visión distorsionada de la construcción del conocimiento científico. Además, dicha visión ha hecho que se vea desfavorecido el desarrollo de procesos cognitivos de orden superior de los sujetos, por limitar este espacio de aprendizaje al seguimiento de guías pautadas con objetivos preestablecidos. En este sentido, se construyó una propuesta teórico-metodológica fundamentada en la teoría de los campos conceptuales de Gerard Vergnaud, en la que se articulan los trabajos prácticos de laboratorio y el uso de tecnologías como los sistemas de adquisición de datos (SAD) para abordar situaciones que favorezcan la conceptualización y, por tanto, los procesos de representación que adquieren gran importancia al considerar el carácter abstracto de la Física. La propuesta se puso en marcha con un grupo de futuros profesores del área de Ciencias Naturales de un programa de Licenciatura de una universidad pública, con quienes se llevó a cabo un estudio de caso desde una perspectiva cualitativa. A partir de los resultados se puede afirmar que los SAD permiten establecer relaciones entre variables, reducen la incertidumbre en la toma de datos y desempeñan un papel importante en el proceso de representación de los fenómenos físicos.

A series of ethyl 2-(2-(arylidene)hydrazinyl)thiazole-4-carboxylates (2a–r) was synthesized in two steps from thiosemicarbazones (1a–r), which were cyclized with ethyl bromopyruvate to ethyl 2-(2-(arylidene)hydrazinyl)thiazole-4-carboxylates (2a–r). The structures of compounds (2a–r) were established by FT-IR, 1H- and 13C-NMR. The structure of compound 2a was confirmed by HRMS. The compounds (2a–r) were then evaluated for their antimicrobial and antioxidant assays. The antioxidant studies revealed, ethyl 2-(2-(4-hydroxy-3-methoxybenzylidene)hydrazinyl)thiazole-4-carboxylate (2g) and ethyl 2-(2-(1-phenylethylidene)hydrazinyl)thiazole-4-carboxylate (2h) as promising antioxidant agents with %FRSA: 84.46 ± 0.13 and 74.50 ± 0.37, TAC: 269.08 ± 0.92 and 269.11 ± 0.61 and TRP: 272.34 ± 0.87 and 231.11 ± 0.67 μg AAE/mg dry weight of compound. Beside bioactivities, density functional theory (DFT) methods were used to study the electronic structure and properties of synthesized compounds (2a–m). The potential of synthesized compounds for possible antiviral targets is also predicted through molecular docking methods. The compounds 2e and 2h showed good binding affinities and inhibition constants to be considered as therapeutic target for Mpro protein of SARS-CoV-2 (COVID-19). The present in-depth analysis of synthesized compounds will put them under the spot light for practical applications as antioxidants and the modification in structural motif may open the way for COVID-19 drug.

Representational Content of Oscillatory Brain Activity during Object Recognition: Contrasting Cortical and Deep Neural Network Hierarchies
Authors: Reddy Leila , Cichy Radoslaw Martin , VanRullen Rufin
Published: April 2021

Numerous theories propose a key role for brain oscillations in visual perception. Most of these theories postulate that sensory information is encoded in specific oscillatory components (e.g., power or phase) of specific frequency bands. These theories are often tested with whole-brain recording methods of low spatial resolution (EEG or MEG), or depth recordings that provide a local, incomplete view of the brain. Opportunities to bridge the gap between local neural populations and whole-brain signals are rare. Here, using representational similarity analysis (RSA) in human participants we explore which MEG oscillatory components (power and phase, across various frequency bands) correspond to low or high-level visual object representations, using brain representations from fMRI, or layer-wise representations in seven recent deep neural networks (DNNs), as a template for low/high-level object representations. The results showed that around stimulus onset and offset, most transient oscillatory signals correlated with low-level brain patterns (V1). During stimulus presentation, sustained β (∼20 Hz) and γ (>60 Hz) power best correlated with V1, while oscillatory phase components correlated with IT representations. Surprisingly, this pattern of results did not always correspond to low-level or high-level DNN layer activity. In particular, sustained β band oscillatory power reflected high-level DNN layers, suggestive of a feed-back component. These results begin to bridge the gap between whole-brain oscillatory signals and object representations supported by local neuronal activations.

Published: April 2021

This research investigates the removal of textile dyes (Rhodamine B and Alizarin Red S) from aqueous solution by a low-cost adsorbent prepared from eggshell waste. Batch adsorption experiments were conducted in order to determine the effect of different parameters such as pH, dye concentration, contact time, adsorbent dosage, particle

size, and temperature. The best correlation was found by Langmuir model, and the maximum adsorption capacity was 175.58 mg g–1 for Rhodamine B and 156.56 mg g–1 for Alizarin Red S. Thermodynamic studies showed that the adsorption of Rhodamine B and Alizarin Red S were feasible, spontaneous, and exothermic in nature. Regeneration study conducted to test the reusability (five cycles) and comparison of adsorption capacities of Rhodamine B and Alizarin Red S showed that calcined eggshell adsorbent could potentially be used for the removal of dyes from aqueous solutions.

In this sense, self- efficacy becomes relevant, since this constitutes a factor in the achievement of goals of an individual, so it is necessary to evaluate it in future graduates (n=443) using valid and reliable scales. To this aim, a scale for measure self-efficacy for communication within work environments was validated and it’s reliability calculated. To obtain the validity of content, the CVI method was used, and for internal consistency, the Spearman-Brown method was applied as well as Cronbach’s alpha coefficient. A factorial analysis was made to obtain construct validity. Results shows, high levels of CVI (.87) and internal consistency (R = .94, α = .93). Also, four factorsthat explain the 66 % of variance were obtained. The instrument is valid and reliable to measure self-efficacy for communication within workenvironments in future graduates.

Paciente masculino, de 32 años, acudió a la Clínica de Prótesis Parcial Fija (PPF), de la Facultad de Odontología de Araçatuba-Universidad Estadual Paulista, manifestando como queja principal que sus dientes anteriores estaban “feos y rotos”. Después del examen clínico, el paciente fue diagnosticado con desorden temporomandibular, bruxismo y presencia de erosiones dentarias (intrínsecas y extrínsecas). Se propuso el acompañamiento de un médico gastroenterólogo y la rehabilitación con prótesis libres de metal (11, 12, 21 y 22) confeccionadas en silicato de litio reforzado con zirconio por el sistema CAD/CAM. Después de la endodoncia de los incisivos antero-superiores, fueron instalados los pernos de fibra de vidrio anatomizados con resina compuesta; la impresión fue realizada con hilo retractor y silicona de adición. Después de la prueba estética y ajustes oclusales, las PPFs de e-max Ceram, fueron preparadas para cementación resinosa con el sistema Variolink II color Light. Después de 1 semana, se tomó la impresión de la arcada superior y posteriormente se le instaló una placa miorrelajante. El paciente y los profesionales involucrados aprobaron el resultado final, comprobando la eficacia estética asociada al uso de prótesis libre de metal, a pesar de que el paciente presenta compromiso gastroesofágico y desorden temporomandibular.

Sr. Editor.

Debido a la propagación del COVID-19, han surgido nuevos protocolos de atención odontológica para poder controlar esta pandemia. Se sabe que una de las principales formas de ingreso del SARS-CoV-2 a nuestro organismo es a través de la cavidad bucal ya que las glándulas salivales menores y botones gustativos están cargados de receptores ACE-2 1. Por eso, consideramos que es importante fomentar el uso de enjuagues bucales preoperatorios durante la consulta odontológica para reducir la carga viral en boca y así prevenir la propagación de este virus entre el paciente y el operador. La presente carta al editor tiene como objetivo fundamentar la importancia del uso de estos colutorios.

Melophagus ovinus (oveja ked) es un parásito común del ovino, su control se basa en tratamientos químicos; sin embargo, las consecuencias de tipo ambiental y en la salud pública obliga a la aplicación de tratamientos alternativos como los hongos entomopatógenos. El estudio tuvo como objetivo determinar el efecto del hongo Beuveria bassiana sobre el parásito en ovinos naturalmente infestados. Se utilizaron 15 ovejas adultas Hampshire cruzadas, distribuidas al azar en tres tratamientos de aspersión con diluciones: T1: 3.2 x108 conidios/ml, T2: 3.2x108 conidios/ml + 5% de azúcar y T control: Agua destilada. Se realizó el conteo diario de los parásitos sobre el animal para determinar la densidad poblacional y la eficacia de los tratamientos. La densidad poblacional fue controlada a partir del día 14 con B. bassiana, reduciendo la presencia de la ked en un 90% (T1 y T2), frente a un 5.9% en el T Control (p<0.05). El estudio sugiere que B. bassiana funciona con una eficacia de 89.3% para el control de M. ovinus

Ateles chamek (Humboldt, 1812) es una especie “En Peligro” y está incluida en el Apéndice II de la CITES, debido a la caza para comercio ilegal y deterioro de su hábitat. Por ello, se han creado centros de rescate para su protección y, en lo posible, retorno a su ambiente natural; sin embargo, el cautiverio, alimentación y manejo pueden promover el desarrollo de parasitosis. El objetivo del presente estudio fue determinar la relación entre endoparasitismo, bioquímica sanguínea y condición corporal en 20 individuos de la especie A. chamek del Centro de Rescate Taricaya, Madre de Dios. Se tomaron muestras de heces y sangre durante el control sanitario. La condición corporal se determinó bajo la escala basada en primates Macaca mulata. Las heces se procesaron con el método de flotación en solución de sal y azúcar; y el plasma sanguíneo fue analizado con un procesador bioquímico. En el análisis coprológico se encontró Strongyloides sp (1/20), Molineus sp (1/20), Ascaris sp (1/20), Physaloptera sp (1/20), Trichuris sp (1/20), Entamoeba sp (1/20), Giardia sp (3/20) y un nematodo ascaroideo no identificado (1/20). Se obtuvieron valores de glucosa 97.8±12.1 mg/dl, proteína total 7.09±0.337 g/dl, bilirrubina total 0.12±0.0219 mg/dl y albúmina 5.47±0.416 g/dl. La condición corporal fue de 2.3±0.219. So se encontró asociación significativa entre las variables en estudio con la parasitosis.

Este relato tem como temática as relações de gênero na formação inicial de professores/as. Teve como objetivo compreender as concepções dos estudantes do Curso Normal sobre gênero, com o intuito de desconstruir os estereótipos sociais instituídos. Esta pesquisa em educação, de abordagem qualitativa, foi realizada através de uma pesquisa-ação. Primeiramente desenvolveu-se uma pesquisa bibliográfica com autores da área, em seguida foi realizada a aplicação de um questionário a 27 estudantes de uma escola estadual de Santa Rosa/RS. As análises dos resultados foram realizadas por meio de categorias definidas a priori, que são: concepção de gênero; importância do estudo das temáticas; participação em atividades referentes à sexualidade e gênero. Ao final das atividades propostas nesta intervenção, percebeu-se que muitos estudantes mudaram suas concepções, adquirindo e desenvolvendo conhecimentos acerca da temática. A partir disso, é possível compreender que é importante trabalhar, com os alunos, assuntos que ainda hoje são considerados tabus, e fazer isso por meio de uma perspectiva dialógica é primordial, uma vez que a escola tem o papel de formar cidadãos críticos e reflexivos, de formar para a cidadania.

The conflict between the parents which then leads to a struggle for custody of the child clearly greatly affects the psychological condition of the child. It is the duty of a judge to provide the best interests as a form of protection for the child. The results of this study indicate: the right of ex officio judges is used or applied in the context of certainty, justice and legal benefits for both parties and especially for the child himself, hadhanah or post-divorce care for the child places the child's position as a party that must be protected and is a joint obligation of both parents. in the best interest of the child.
