Aspects regarding the use of passive filters for harmonic mitigation in power rectifiers
Authors: Vlad Mocanu
Published: October 2021

The power rectifiers, along with other types of static converters are present in the power generation systems of naval vessels, whose powers reach the order of hundreds of MW. This fact, inevitably leads to the appearance of harmonics with very high weights. As a solution for the problem of harmonics mitigation, the authors conceived several simulation in Matlab Simulink relating to the efficiency of different type of passive filter. These simulations took into account the characteristics of the main types of passive filters used on board ships, highlighting at the same time, the steps for calculating the constructive elements.

Transcriptome Analyses of Pre-parasitic and Parasitic Meloidogyne Chitwoodi Race 1 to Identify Putative Effector Genes
Authors: Zhang Lei , Gleason Cynthia
Published: October 2021

Meloidogyne chitwoodi is a root-knot nematode that is a major pest of potato in the northwestern United States. Due to the lack of resistance against root-knot nematodes in potato, research has been undertaken to understand the M. chitwoodi-potato interaction at the molecular level. To identify the nematode genes that are playing roles in parasitism, we have performed transcriptome analyses on pre-parasitic and parasitic M. chitwoodi juveniles in susceptible potato. We compared gene expression profiles and identified genes that were significantly up- or down- regulated during nematode parasitism. Because parasitism proteins are typically secreted by the nematode to facilitate infection of host roots, we focused on the genes that encoded proteins that were predicted to be secreted. We found that approximately 34% (43/127) of the genes in the predicted secretome encoded proteins with no significant homology in the public genome databases, and 12% (15/127) encoded either a known effector, putative effectors or putative esophageal gland cell proteins. The transcriptome analyses of M. chitwoodi at the pre-parasitic and parasitic life stages shed light on the genes involved in nematode parasitism.

Authors: Kien Phan Trung , Hong Thuy Nguyen Thi , Ha Dang Thu , Thuan Tran Van , Ngoc Le Kim
Published: October 2021

Non-financial factors including quality of services, the flexibility of a company, utilization of resources, and market orientation are regarded as significant determinants that enhance the profitability-based performance of a service company or a hotel. The study investigated the interaction between these factors and hotel operating performance measured by the hospitality performance and results indicators. Data on 346 executives of Vietnam’s hospitality companies were collected. A structural equation modeling (SEM) method was utilized to examine the positive-direct and moderating effects of non-financial factors on hotel performance in terms of occupancy rate (OCR), average daily rate (ADR), and the revenue per available room (RevPAR). The findings showed that service quality ( = 0.118, p < 0.05), flexibility ( = 0.173, p < 0.05) and resource utilization (= 0.172, p < 0.05) positively affected the performance of Vietnam’s hospitality companies. Meanwhile, innovation showed no direct influence (p = 0.068) but an indirect impact on the performance through service quality ( = 0.311, p < 0.05). Market orientation did not impact the performance (p = 0.076) but it positively affected both innovation ( = 0.322, p < 0.05) and service quality ( = 0.146, p < 0.05). The study contributed to a theoretical enhancement of the current level of knowledge on the factors that affect the performance and developed a reliable scale for measuring the performance of hotels in Vietnam.
Critical Discourse Analysis on Representation of Racism and Solidarity in Adidas's Tweets
Authors: Indrawati Desi
Published: October 2021

The research aimed to analyze how Adidas uses Twitter to convey messages about racism and solidarity in its tweets. Methodologically, the research applied a descriptive qualitative study on the representation of racism in Adidas’s tweets involving (1) what are the themes of discourses that represent racism and solidarity in Adidas’s tweets? (2) What is the representation of racism and solidarity in Adidas’s tweets? And (3) What are the meanings of Adidas’s tweets? Twelve tweets from Adidas were collected, coded, analyzed, and described using Critical Discourse Analysis (CDA). It was an effective method for deconstructing the identity of Twitter users to make arguments on the themes exposed during coding. The research findings reveal that the declarative statement and humanitarian as the most themes in Adidas’s tweets are the ones that give straightforward and positive messages to Twitter users and followers. The findings also indicate firm and meaningful tweets for Adidas to speak out against racism and spread solidarity through Twitter. However, those tweets also give the messages about their commitment to always supporting the black community, their black employees, the Asian community, and the Black Lives Matter event to embody valuable and eternal change through solidarity, unity, and commitment against racism.
Neurotechnologies: Development, practical application and regulation
Authors:   National Research Lobachevsky State University of Nizhny Novgorod, Filipova Irina A.
Published: October 2021

Neurotechnology is one of the groups of technologies called disruptive or cross-cutting digital technologies. The spread of these technologies in many sectors of the economy can radically change human society. The state contributes to the development of technology when it implements strategic development programs and creates special legislation. The lack of regulation is an obstacle to the development and dissemination of this technology in practice. Therefore, the regulation of artificial intelligence technologies is actively created in the modern world. The law practically does not regulate other cross-cutting technologies, including neurotechnologies. The uncertainty of the further development of technologies and the impossibility of accurate forecasting of development explain the lack of regulation. At the same time, neurotechnologies are increasingly used in practice (neural implants, neural interfaces). According to experts, the pace of development of neurotechnologies in the next decade will lead to an explosive increase in their distribution in society. The subject of research in this article is the study of the need for the creation of special regulation. The objectives of the study include the analysis of risks associated with the development of neurotechnologies and the substantiation of opportunities to eliminate risks through legal regulation. Methods of system analysis, abstraction, legal modelling, the formal-logical method and the comparativelegal method are used in this study. The result of the work includes a greater likelihood of the future integration of the human body and artificial intelligence into a single system due to the development of neurotechnologies, which will require a rethinking of some personal and socio-economic human rights.

for the Treatment of COVID-19 Infection
Authors: De Vito Danila , Fusco Antonio , Benincasa Caterina , Laghi Luca , Ceruso Francesco M.
Published: October 2021

Background:

World Health Organization (WHO) has increasingly improved the guidelines
to tackle the spread of Coronavirus Disease 2019 (COVID-19) among the worldwide population.
In this context, each country has introduced specific social, healthcare, political and macroeconomic
measures to face COVID pandemic locally.

Objective:

The general aim of this comparative overview is to highlight the most significant effects
of COVID-19 pandemic on the main healthcare systems. Also, we critically analyzed the macroeconomic
variables and the most promising solutions to improve both healthcare system and its related
risk management, taking into specific consideration the most industrialized countries.

Method:

The main strategy has been built on a renewed concept of the hospital, rebuilding the old
concepts of “triage” and “intensive care”. Recently, COVID-19 hospitals have allowed to cater the
patients affected by COVID-19. Moreover, the reshaping of several healthcare policies and requirements
has led to several positive effects, such as the recruitment of a huge number of human resources
in the healthcare systems. Nevertheless, several negative effects have also impacted the
communities mostly subjected to infections.

Conclusion:

Undoubtedly, the national healthcare systems have somehow addressed the people’s
needs, trying not to neglect the social, healthcare, economic and political aspects. In our overview,
we have reported how the different actions taken in the last months, have resulted in different outcomes.

Background:

Coronavirus Disease 2019 (COVID-19) rapid manifestation and spread have disrupted world norms and affected people's daily activities and life. Many ministries chose mass lockdown protocol as a way to control the virus spread. Though this protocol has shown to be effective in limiting the Virus transmission, it might have a negative impact on the population's psychological status, such as boredom, confusion, psychological stress, anxiety, depression, and physical effects.

Objective:

This study aimed to find the impact of the COVID-19 pandemic on the Palestinian adults' psychological status by assessing the participant's practices, reports of anxiety and depression during the pandemics

Methods:

An observational descriptive cross-sectional study was conducted among Palestinian adults in the West Bank, at the occupied Palestinian territories, between July and September 2020. The questionnaire was structured into two domains: the first domain includes nine questions about sociodemographic data. The second consisted of 33 (yes and no) questions evaluating the participant's psychological status.

Results:

739 participants with a mean age of 31.76, filled the online questionnaire. Around one-third of respondents revealed having many signs of anxiety, and around 42% of respondents expressed having many signs of depression. Females were significantly more likely to have signs of depression, whereas front-line COVID-19 health care workers were significantly the least likely to have signs of depression and no signs of depression were found among participants with high incomes.

Conclusion:

COVID-19 pandemic has a negative effect on mental status; most participants have signs of anxiety and depression.
Potential Utility of Radiopharmaceuticals in the Battle Against SARSCov-
2 and COVID-19 Pandemic
Authors: Sager Omer , Dincoglan Ferrat , Demiral Selcuk , Beyzadeoglu Murat
Published: October 2021

:

Coronavirus disease 2019 (COVID-19) pandemic, which has emerged in December
2019 in the city of Wuhan, China, has significantly affected healthcare systems and economies
within a short timeframe. Treatment strategies offer alleviation of symptoms in the absence of commercially
available specific antiviral agents. Within this context, the introduction of innovative therapeutic
approaches against the SARS-CoV-2 virus is a critical need that should be addressed urgently.
The anti-inflammatory effect of low dose irradiation has been proposed as a potential therapeutic
strategy for COVID-19 pneumonia. Consideration of external beam irradiation for management of
COVID-19 pneumonia has prompted the investigation of alternative methods of irradiation with potentially
improved toxicity profiles. Theoretically, targeted radiotherapy may have several advantages
over conventional external beam radiotherapy owing to the capability to deliver effective radiation
doses without adverse irradiation effects. Since radionuclides are conjugated to targeting vectors,
such as antibodies and cell surface receptor binding peptides, irradiation may be focused on
targeted cells with optimal sparing of surrounding normal tissues. In the context of COVID-19 management,
targeted irradiation is expected to compromise SARS-CoV-2 extracellular virions.
Targeted radiotherapy may offer a viable means of combating against SARS-CoV-2 virus. There is
room for improvement with the need for efficacy, feasibility, and toxicity studies. Although targeted
radiotherapy itself may not achieve absolute eradication of virus or virus-infected cells, it may
at least serve as a supplementary therapeutic strategy that could be utilized in combination with
other antiviral treatments. Further investigations focusing on nuclear medicine, radiopharmaceuticals,
and targeted radiotherapy strategies may pave the way for the development of efficacious antiviral
treatments which may be utilized in the battle against the current COVID-19 pandemic.

Authors: Mphekgwana Peter M. , Makgahlela Mpsanyana , Mothiba Tebogo M.
Published: October 2021

Introduction:

The coronavirus (COVID-19) pandemic has caused major public respiratory illness worldwide. To date, no specific treatment for COVID-19 has proven effective, thus leading people to rely on diverse measures including the use of traditional medicines.

Aim:

The study aimed at determining the prevalence of traditional medicine use amongst university staff and students, and to examine the association of traditional medicine use with mental status and health parameters.

Methods:

A quantitative descriptive cross-sectional design research method was used in this study. The targeted population was the university staff members and students in one rural-based university.

Results:

A total of 400 individuals in rural-based university responded to the online survey; approximately more than three quarters were students 313 (78.3%) and single (86%). The ages of participants ranged from 17 to 66 years, with a median age of 22 years. The prevalence of the use of traditional medicines to respond to COVID-19 was 30.4%. A significantly higher proportion of use of traditional medicines was by participants with mental health impacts (62% vs. 37%), those who postponed medical appointments (48% vs. 22%) and those who failed to buy prescribed medications (36% vs. 14%).

Conclusion:

A considerable proportion of university staff members and students were found to be using traditional medicines in responding to COVID-19 during the South African nationwide lockdown. Policymakers and researchers are recommended to look more into the health benefits of traditional medicines, including clinical trials, to establish medicinal safety and efficacy.
Return Migrants Reintegration Projects in West Africa: Critical Notes on the Sahel
Authors: Eyebiyi Elieth , Allossoukpo Eugène
Published: October 2021

Migration issue is more than ever on the agenda of global concerns, particularly with regard to Africa, even though human mobility remains essentially internal on the African continent and rooted in centuries-old circulatory traditions. While a large literature emphasizes the criminalization of migration from the South to the North, but also the policies of outsourcing borders and the control of flows, the links between migration and development are still poorly studied, particularly with regard to the returnees, expelled and other categories (re) integration. However, return migrants are often at the heart of different logics and realities in tension, especially in the context of various reintegration projects, with mixed results. This paper contributes to rethink critically the public policies of reintegration of return migrants in Sub-Saharan Africa as a component of the European Union governance of migration, and in a context of regional free movement promotion. It is based on a combined analysis of some projects implemented as part of the transfer of European migration governance policies and measuring the scope, but also their inconsistencies.

Authors: Kunonga Tafadzwa Patience , Spiers Gemma Frances , Beyer Fiona R , Hanratty Barbara , Boulton Elisabeth , Hall Alex , Bower Peter , Todd Chris , Craig Dawn
Published: October 2021

Background

The 2020 COVID-19 pandemic prompted the rapid implementation of new and existing digital technologies to facilitate access to health and care services during physical distancing. Older people may be disadvantaged in that regard if they are unable to use or have access to smartphones, tablets, computers, or other technologies.

Objective

In this study, we synthesized evidence on the impact of digital technologies on older adults’ access to health and social services.

Methods

We conducted an umbrella review of systematic reviews published from January 2000 to October 2019 using comprehensive searches of 6 databases. We looked for reviews in a population of adults aged ≥65 years in any setting, reporting outcomes related to the impact of technologies on access to health and social care services.

Results

A total of 7 systematic reviews met the inclusion criteria, providing data from 77 randomized controlled trials and 50 observational studies. All of them synthesized findings from low-quality primary studies, 2 of which used robust review methods. Most of the reviews focused on digital technologies to facilitate remote delivery of care, including consultations and therapy. No studies examined technologies used for first contact access to care, such as online appointment scheduling. Overall, we found no reviews of technology to facilitate first contact access to health and social care such as online appointment booking systems for older populations.

Conclusions

The impact of digital technologies on equitable access to services for older people is unclear. Research is urgently needed in order to understand the positive and negative consequences of digital technologies on health care access and to identify the groups most vulnerable to exclusion.
Adoption of Machine Learning Systems for Medical Diagnostics in Clinics: Qualitative Interview Study (Preprint)
Authors: Pumplun Luisa , Fecho Mariska , Wahl Nihal , Peters Felix , Buxmann Peter
Published: October 2021

BACKGROUND

Recently, machine learning (ML) has been transforming our daily lives by enabling intelligent voice assistants, personalized support for purchase decisions, and efficient credit card fraud detection. In addition to its everyday applications, ML holds the potential to improve medicine as well, especially with regard to diagnostics in clinics. In a world characterized by population growth, demographic change, and the global COVID-19 pandemic, ML systems offer the opportunity to make diagnostics more effective and efficient, leading to a high interest of clinics in such systems. However, despite the high potential of ML, only a few ML systems have been deployed in clinics yet, as their adoption process differs significantly from the integration of prior health information technologies given the specific characteristics of ML.

OBJECTIVE

This study aims to explore the factors that influence the adoption process of ML systems for medical diagnostics in clinics to foster the adoption of these systems in clinics. Furthermore, this study provides insight into how these factors can be used to determine the ML maturity score of clinics, which can be applied by practitioners to measure the clinic status quo in the adoption process of ML systems.

METHODS

To gain more insight into the adoption process of ML systems for medical diagnostics in clinics, we conducted a qualitative study by interviewing 22 selected medical experts from clinics and their suppliers with profound knowledge in the field of ML. We used a semistructured interview guideline, asked open-ended questions, and transcribed the interviews verbatim. To analyze the transcripts, we first used a content analysis approach based on the health care–specific framework of nonadoption, abandonment, scale-up, spread, and sustainability. Then, we drew on the results of the content analysis to create a maturity model for ML adoption in clinics according to an established development process.

RESULTS

With the help of the interviews, we were able to identify 13 ML-specific factors that influence the adoption process of ML systems in clinics. We categorized these factors according to 7 domains that form a holistic ML adoption framework for clinics. In addition, we created an applicable maturity model that could help practitioners assess their current state in the ML adoption process.

CONCLUSIONS

Many clinics still face major problems in adopting ML systems for medical diagnostics; thus, they do not benefit from the potential of these systems. Therefore, both the ML adoption framework and the maturity model for ML systems in clinics can not only guide future research that seeks to explore the promises and challenges associated with ML systems in a medical setting but also be a practical reference point for clinicians.

Caking Phenomena During Pilot-Scale Crystallization of Dextrose Monohydrate
Authors: Kartika Bayu Mahdi , Harsojo Harsojo , Rismana Eriawan
Published: October 2021

Dextrose Monohydrate (DMH) is a bulk chemical used in the food, beverage, and pharmaceutical industries. The caking often appeared in the crystallization of DMH. Caking is an agglomeration that can affect the product quality of DMH and is dependent on the type of impeller. This study aimed to determine the type of impeller to avoid the caking during the DMH crystallization and identify the DMH caking. The results showed that caking did not occur on the helical ribbon and anchor impeller, while caking appeared on the Rushton turbine impeller. Computational fluid mechanics (CFD) analysis showed that caking occurs due to uneven homogeneity of stirring. Fourier transform infrared (FTIR) and X-ray diffraction (XRD) studies showed that DMH caking and non-caking had the same peak pattern. Meanwhile, optical microscope and scanning electron microscope (SEM) analysis showed that the DMH caking seen agglomerate. Density analysis showed that DMH with caking was 1.257–1.350 kg/L, while the non-caking was 0.504–0.780 kg/L. Caking phenomena during the DMH crystallization can be avoided by using a helical ribbon and anchor impeller. FTIR and XRD analysis cannot be used to identify DMH caking products; meanwhile, optical microscope, SEM, and density analyzes can be used to identify DMH caking products.

Published: October 2021

In Indonesia, the composition of waste has gradually changed over time. To reduce expanded polystyrene (EPS) foam waste, we converted it into a heterogeneous acid catalyst, namely Polystyrene Sulfonic Acid (PSSA). The catalyst was then used in an esterification reaction to generate triacetin. In this research, the synthesis of PSSA was performed using a sulfonation reaction with silver sulfate (Ag2SO4) as the catalyst. Based on FTIR analysis, the sulfonation reaction was successful. The use of 0.5% and 1% catalysts led to a significant increase in the degree of sulfonation of PSSA, while there was a relatively constant increase when using 1.5–2.5% catalysts. The highest degree of sulfonation (78.63%) was achieved when the reaction was performed using 2% Ag2SO4 catalyst for 25 min. The PSSA with the highest degree of sulfonation was characterized using X-Ray Diffraction (XRD), SEM-EDX, and BET-BJH. This PSSA had a semi-crystalline structure with a crystallinity of 73.83%, a particle size of 1.75 nm, mesoporous pores with a radius of 16.984 Å, and a sulfur content of 15% (% mass).

Published: October 2021

Dipterocarpus cornutus Dyer is commonly known as ‘keruing’. It belongs to the family of Dipterocarpaceae, an important timber family in South East Asia. D. cornutus is listed as critically endangered on IUCN Red List. Since no comprehensive study has been documented on the chemical constituents of D. cornutus, there is an urgent need to study this plant comprehensively. Phytochemical study of the stem bark of D. cornutus afforded a new flavonoid (1) and nine known compounds, which consist of flavonoids (2, 3), oligostilbenoids (4, 5, 7, 8, 9, 10), and coumarin (6). The finding of the study contributes to the chemotaxonomic differentiation in the plants of the tribe Dipterocarpae.

O cuidado como acolhimento à diferença na educação inclusiva
Authors: Araújo André Luiz de , Cruz Juliana Boff Aramayo , Silva Rafael Furtado da , Rocha Renata Cristina Alves da
Published: October 2021

O presente artigo reflete sobre o cuidado como preocupação e atenção no processo de ensino-aprendizagem dos educandos com deficiência intelectual. A pesquisa surge da práxis pedagógica na educação inclusiva. Utiliza-se como metodologia a revisão bibliográfica, com aporte reflexivo e crítico, baseada no conceito de cuidado do filósofo Martin Heidegger (2005), do filósofo e teólogo Leonardo Boff (2013, 2014) e da educadora Luigina Mortari (2018). Na Fábula-mito do cuidado, citada na obra Ser e Tempo de Heidegger (2005) e posteriormente interpretada por Leonardo Boff (2014) no livro Saber cuidar, o cuidado já era considerado essencial para a existência humana. Cuidar, no âmbito da educação inclusiva, significa valorizar a dignidade humana, a autonomia e o espaço acessível para a reflexão–ação. Além disso, reflete-se sobre o cuidado e a educação inclusiva, como atenção às diferenças e acolhimento do outro. Conclui-se que uma educação, centrada no cuidado, prioriza o diálogo, preocupa-se com a vida e reconhece a singularidade e a pluralidade dos sujeitos.

Como aporte teórico-metodológico das atividades, utilizaram-se: (a) as teorias cognitivas, que contemplam o raciocínio simbólico e a aquisição de linguagem no processo de ensino-aprendizagem de idiomas; e (b) os estágios do desenvolvimento cognitivo-emocional, teorizados por Jean Piaget e Lev Vygotsky. Para os autores, a aquisição da linguagem é o resultado da prática e da formação de hábitos; tal processo acontece quando as crianças imitam os sons que ouvem, interagem com objetos/imagens e recebem reforços positivos. Logo, é importante que os educandos sejam estimulados a usarem, processualmente, a língua inglesa em seu cotidiano.
Pensamento computacional na cidade: uma vivência de educação onlife

Published: October 2021

Experienciar a cidade enquanto espaço de aprendizagem implica entrelaçamento de seus vários tempos, espaços e de suas dimensões humanas e não humanas, digitais, biológicas, históricas, econômicas, etc. Entender a cidade como entidade viva, complexa e comunicativa se afasta da visão antropocêntrica de mundo e instaura outras formas de comunicação, habitação e aprendizagem. Portanto, este artigo apresenta o processo de desenvolvimento de uma prática pedagógica gamificada cujo objetivo é compreender como o coengendramento dos diversos entes constituintes da cidade produz o pensamento computacional na perspectiva da aprendizagem inventiva, segundo uma proposta de Educação OnLIFE. Tal prática integra o projeto de pesquisa A cidade como espaço de aprendizagem: práticas pedagógicas inovadoras para a promoção da cidadania e do desenvolvimento social sustentável, financiado pela Fundação Carlos Chagas e pelo Itaú Social, e desenvolvida pelo Grupo de Pesquisa Educação Digital — GPe-dU, UNISINOS/CNPq. O estudo, qualitativo, apropria-se do método cartográfico de pesquisa-intervenção para produção e análise dos dados. Como resultado, apresentam-se pistas que permitem compreender a emergência do pensamento computacional para explorar a cidade, bem como a necessidade de inovação de práticas pedagógicas a partir da problematização do mundo para uma Educação conectada com a vida.

Published: October 2021

O objetivo do presente artigo é identificar as produções acadêmicas realizadas sobre o Farol do Saber e Inovação. Analisa-se, também, em que medida este objeto de estudo dialoga com a questão do território, ao englobar os conceitos de territorialidade, território educativo e cidade educadora.  O referencial teórico destaca autores e pesquisadores como Santos (1985, 2020), Albagli (2004), Haesbaert (2004), Gadotti (2006) e Moll (2019), que alicerçam a fundamentação teórica. Inicialmente, o artigo contextualiza o tema e, em seguida, apresenta a metodologia utilizada; trata-se de uma pesquisa bibliográfica, com uma abordagem quantitativa e qualitativa de dados, conforme Marconi e Lakatos (2003). Nos resultados, discute-se como o Farol do Saber está inserido no território. Conclui-se que a temática é pouco estudada, no entanto, a investigação traz contribuições relevantes sobre o conceito de território educativo,  o que fortalece a perspectiva de uma cidade educadora.

Este artigo apresenta resultados parciais da pesquisa-criação desenvolvida por um conjunto de universidades e escolas parceiras para discutir possibilidades do uso da tecnologia de imersão (vídeo 360 graus) no desenvolvimento de projetos educativos e artísticos. Tem como ponto de partida a valorização do ponto de vista de adolescentes de idades entre 14 e 19 anos, de diferentes origens, matriculados em escolas públicas das periferias do estado do Rio de Janeiro e da província do Quebec, Canadá, para apresentarem suas perspectivas sobre seus territórios através do uso da tecnologia de imersão. Neste artigo, apresentamos diversas modalidades de pesquisa-criação em torno de projeto de desenvolvimento de vídeos 360, que estabelece diálogo entre distintos territórios. Identificamos os diferentes territórios educativos permeados por sujeitos em suas diversidades culturais, políticas, econômicas e sociais, sob a égide das tecnologias e desigualdades sociais. O propósito é apresentar alguns dos desafios dessa produção coletiva e os espaços de encontro criados a partir das novas tecnologias, em um percurso que exigia revisitar a memória de um território — quando este se viu limitado por medidas sanitárias em contexto da pandemia de COVID19 — e o desvelar de outros territórios, mais intimistas e singulares, ressignificando os espaços de circulação a partir da re(construção) de histórias, valores e de modos de percepção do mundo.
ADDITIONAL DIET INFORMATION FOR Cerrophidion godmani (GÜNTHER, 1863) AND A DIETARY SYNOPSIS OF THE GENUS Cerrophidion CAMPBELL AND LAMAR, 1992
Authors: Schramer Tristan David
Published: October 2021

The montane pitvipers (Cerrophidion spp.) consist of five recognized species that disjunctly occupy high elevational habitats from southern Mexico to western Panama. However, two of these species were recently delineated, leaving previously published natural history data on Cerrophidionoutdated and in need of a re-examination. To gain more information, we investigated the stomach contents of Cerrophidion specimens housed in the University of Illinois Museum of Natural History Herpetology Collection (UIMNH) and report our findings. We also compiled lists of all known prey items and present a comprehensive dietary synopsis for each species of Cerrophidion according to recent taxonomic changes. These efforts unearthed eleven previously undocumented prey items for three of the species.

Authors: DEL MORAL FLORES LUIS FERNANDO
Published: October 2021

Se presenta el primer registro del cocodrilo de pantano, Crocodylus moreletii, para la Selva zoque de Los Chimalapas, en Oaxaca, México. Oaxaca es el estado con mayor riqueza de anfibios y reptiles en México, y la región de Los Chimalapas es una de las selvas mejor conservadas del país. Durante un muestreo de vertebrados, se avistaron varios ejemplares de C. moreletti en pozas de la comunidad La Fortaleza, Santa María Chimalapa, colindantes al Río Oaxaca. Este registro demuestra la falta de estudios faunísticos en la región.

¿Cómo lograr la excelencia sanitaria en la atención del paciente con enfermedad renal crónica? Desarrollo de vías clínicas para los estadios iniciales de la enfermedad
Authors: Navarro Jiménez Eduardo Ignacio , Laborde Cárdenas Carmen , Aroca Martínez Gustavo , Nicholls De La Hoz Victoria , Hernández Berrios Camila , Olivero Pacheco Bryan , Castillo Parodi Luis
Published: October 2021

Las vías clínicas son instrumentos desarrollados para planificar y coordinar la secuencia de procedimientos clínicos y administrativos necesarios para conseguir la máxima calidad asistencial. Su rápida difusión en EE. UU. explica que más del 60% de los hospitales usen vías clínicas para sus procesos más frecuentes. Esto contrasta con su escasa implementación en Colombia y los países de la Región de las Américas. Las Vías Clínicas se ajustan con el cambio que representa el enfoque en procesos, orientado a optimizar una mejor atención al paciente.

Published: October 2021

Introducción:
La enfermedad renal crónica avanzada se define como la presencia de daño renal y se caracteriza por alteraciones estructurales y funcionales que disminuyen la tasa de filtración glomerular. Esta enfermedad constituye un punto de cambio en la vida de las personas que la padecen, pues los obliga a diseñar estrategias mediante las cuales puedan reestructurar sus sueños, aspiraciones y proyectos de vida debido a que esta es una condición que cambia los estilos de vida y ocasiona otras entidades que afectan los niveles físico, psicológico y social.
Objetivo:
Determinar los factores asociados a la depresión en personas con enfermedad renal crónica avanzada en población del departamento de Boyacá, Colombia.
Materiales y métodos:
Se realizó un estudio transversal en 201 pacientes con enfermedad renal crónica en fases avanzadas y que estuvieran en manejo con terapia dialítica. Para la obtención de los datos se aplicó el cuestionario de depresión de Beck, además se incluyeron variables demográficas, sociales y clínicas.
Resultados:
La edad promedio de los participantes fue 58,5 años, el 76,11 % eran varones y la prevalencia de depresión fue de 40,29 %. Las personas con pareja estable y que cuentan con apoyo familiar y buena atención por parte del personal de salud tienen menos probabilidad de presentar depresión, mientras que los mayores de 50 años de edad, quienes llevan más dos años en terapia dialítica y aquellos que presentan otras enfermedades como diabetes mellitus y enfermedad pulmonar obstructiva crónica tienen probabilidades más altas de desarrollar depresión.
Conclusiones:
Se considera prudente crear  grupos  de  apoyo  en  las  unidades  de  diálisis,  donde  se incluya  a  los  pacientes  y  sus  familiares,  con  el  fin  de  detectar  tempranamente  problemas  de  salud mental y darles un manejo temprano, buscando de esta forma una adecuada adherencia al tratamiento de las patologías de base.
