Authors: Degu Sileshi , Abebe Abiy , Gemeda Negero , Bitew Adane
Published: August 2021

The high prevalence of morbidity and mortality from bacterial infections, together with the growing threat of antibacterial resistance, necessitated the development of alternative new drugs from traditional medicine. In Ethiopia,Impatiens tinctoriaA. Rich has been traditionally used for the treatment of fungal infections such as ringworms that cause tinea pedis and it have also different medical values. Scientific information on its biological activity against a broad range of bacteria and safety data is scant, compared to its folklore data. In this study, we evaluated antibacterial activities and acute oral toxicity of aqueous, ethanol and ethyl acetate root extracts ofImpatiens tinctoriaA. Rich. Aqueous, ethanol and ethyl acetate extracts of the plant were evaluated using agar hole diffusion and agar dilution methods. Biological activities of the plant extracts were expressed as a zone of inhibition diameter, minimum inhibitory concentration (mg/ml), and minimum bactericidal concentration (mg/ml). The safety studies were performed by oral acute toxicity study according to the organization of economic cooperation and development test Guidelines 420.Gram-positive bacteria were more susceptible to the extracts compared to gram-negative bacteria, especially againstS.aureusandS.epidermidis, which are commonly found in the skin. Ethyl acetate extract was more potent than ethanol and aqueous extracts. The 50% lethal dose (LD50) of tested mice was above 9600 mg/kg. This study provides a scientific basis for the antibacterial activity of the root extracts of I.tinctoriaA. Rich, where, the ethyl acetate extract showed the most promising activity. Therefore, the antibacterial potential and practical non-toxicity of the study plant extracts suggested the possibility of using it for the development of antimicrobial drugs by further studying the plant in different directions.

Objective

The study aimed to explore the experiences of women undergoing Assisted Reproductive Technologies namely; Invitro Fertilization and Intracytoplasmic Sperm Injection at the Finney Hospital and Fertility Centre, New Bortianor, Ghana.

Method

A qualitative research design was employed to analyse and describe the experiences of the women seeking Assisted Reproductive Technologies. A total of 32 women were invited to take part in the interview, 15 of them accepted the invitation. However, saturation was reached before all interviews had been complete.

Results

Three themes emerged from the study: the women’s experiences, challenges and the roles and contributions of significant others. The women were anxious, stressed-up, exhausted and financially burdened. Spouses and health professionals played significant roles by providing social, emotional and financial support for these women. Significant others such as spouses and close relatives were supportive and provided encouragement to the women.

Conclusion

The experiences of women undergoing Assisted Reproductive Technologies are multi-dimensional. Thus, psychosocial interventions as part of ART services with health insurance cover may be client-centered and more appropriate for these group of women.

The purpose of this study was to develop a simulation approach for predicting maxillomandibular advancement-induced airway changes using computational fluid dynamics. Eight patients with jaw deformities who underwent maxillomandibular advancement and genioglossus advancement surgery were included in this study. Computed tomography scans and rhinomanometric readings were performed both preoperatively and postoperatively. Computational fluid dynamics models were created, and airflow simulations were performed using computational fluid dynamics software; the preferable number of computational mesh points was at least 10 million cells. The results for the right and left nares, including simulation and postoperative measurements, were qualitatively consistent, and surgery reduced airflow pressure loss. Geometry prediction simulation results were qualitatively consistent with the postoperative stereolithography data and postoperative simulation results. Simulations were performed with either the right or left naris blocked, and the predicted values were similar to those found clinically. In addition, geometry prediction simulation results were qualitatively consistent with the postoperative stereolithography data and postoperative simulation results. These findings suggest that geometry prediction simulation facilitates the preoperative prediction of the postoperative structural outcome.

Since the pandemic of COVID-19 has intensely struck human society, small animal model for this infectious disease is in urgent need for basic and pharmaceutical research. Although several COVID-19 animal models have been identified, many of them show either minimal or inadequate pathophysiology after SARS-CoV-2 challenge. Here, we describe a new and versatile strategy to rapidly establish a mouse model for emerging infectious diseases in one month by multi-route, multi-serotype transduction with recombinant adeno-associated virus (AAV) vectors expressing viral receptor. In this study, the proposed approach enables profound and enduring systemic expression of SARS-CoV-2-receptor hACE2 in wild-type mice and renders them vulnerable to SARS-CoV-2 infection. Upon virus challenge, generated AAV/hACE2 mice showed pathophysiology closely mimicking the patients with severe COVID-19. The efficacy of a novel therapeutic antibody cocktail RBD-chAbs for COVID-19 was tested and confirmed by using this AAV/hACE2 mouse model, further demonstrating its successful application in drug development.
Where have all the colours gone?: Land of Darkness in the work of Dia al-Azzawi
Authors: Macmillan Louisa
Published: August 2021

This article is an overview of the evolution of the ongoing series Land of Darkness by Dia al-Azzawi (born in Baghdad in 1939), which is marked by a lack of colour unusual to Azzawi’s work. This article argues that, although he initially chose the term ‘darkness’ as an ironic reinterpretation of a historic name for Iraq for the title of a single artwork about a specific tragedy, Azzawi was compelled to return to it time and again as he witnessed the ongoing deterioration of his homeland from afar. It also examines how and why, for nearly three decades after the Gulf War of 1991, Azzawi has constantly turned his focus towards Iraq, criticizing its enemies and defending its future, and continuing to make works about the plight of the Land of Darkness.

Proteus ISIS simulation for power factor calculation using zero crossing detector
Authors: Jumrianto Jumrianto , Royan Royan
Published: August 2021

One of the important parameters for electrical systems is the power factor (cos phi), which is the ratio of the real power (watt) to the apparent power (volt ampere). The best cos phi value is between 0.85 to 1. A resistive load causes the voltage and current in equal phase angle, while the inductive load causes the current to lag behind the voltage. On the other hand, the capacitive load causes the current to precede the voltage (leading). A simulation to determine the power factor of an electrical network can be done with Proteus ISIS software by creating a phase detection circuit. Automatic control can be done by a microcontroller. This simulation circuit can be used as power factor correction, a trigger angle on SCR trigger for DC motor speed control, for rocket launch angle adjuster, to measure the angle of inclination, and other uses relating to angle adjustments.
Effect of different drying techniques on the drying time and energy of blueberry
Authors: Antal Tamás
Published: August 2021

Blueberries (Vaccinium corymbosum L.) were dried combining vacuum, infrared, hot-air and freeze drying technologies. In this paper, examined the drying time and energy consumption of dewatering methods. The rehydration as a physical property were evaluated in dried blueberries. Combination of vacuum dried and freeze dried blueberries had higher rehydration ratio, followed by the single freeze drying, combination of hot-air drying and freeze drying, and infrared-freeze drying methods. The performance evaluation indicated that combination drying of blueberries at two-stage infrared-freeze drying with 60°C and 15 min pre-drying reduced the drying time by 53.4%, besides consuming less energy (52.9%) compared to single freeze drying. Based on the results, primarily vacuum pre-drying, infrared pre-drying and freeze finish-drying may be the economical and optimal solution for dehydrating blueberries.

Published: August 2021

Many studies have been trying to establish standard protocols for animal experimentation, especially for animal species or strains, to master research variables with high precision. The main mouse strains used in the field of the biology of reproduction are Swiss, Balb/c, and C57BL/6. Since some of the strains show reproduction limitations, such as the size of the litter, the present study aimed to compare their spermatogenic processes to verify differences regarding the testicular parenchyma and germ cell populations, which could explain low offspring production. In addition, the present study provides additional information concerning the testicular parenchyma of such strains, which consequently would help researchers to choose the most suitable strain for reproductive studies. Six adult male mice were used for each of the strains. After euthanasia, the testes were weighed, fixated with Karnovsky fixative, embedded in methacrylate, sectioned, and stained with toluidine blue/sodium borate 1%. Morphometrical analyses from the testicular parenchyma (seminiferous tubules and interstitium) were made using the software ImageJ. Germ and Sertoli cells populations were counted in seminiferous tubules cross-sections at stage I of the seminiferous epithelium cycle. The lowest body and testicular weights were observed in C57BL/6 animals, followed by Balb/c and Swiss, however, the relative testes, parenchyma, and albuginea weights were significantly lower only in C57BL/6. Despite the seminiferous tubules and seminiferous epithelium proportions were lower in Swiss animals, their relative amount related to the body weight was the same among strains. The total number of germ cells was higher in Swiss animals, reflecting higher spermatogenic yield and daily sperm production. Due to the lower relative number of Sertoli cells, the Swiss animals showed the highest Sertoli cell index and support capacity. On the other hand, the lowest pathological indexes regarding the germ cells were observed in Balb/c animals, followed by Swiss and C57BL/6. In the interstitium, the proportion of blood vessels was lower in Swiss mice, while the lymphatic cell proportion was lower in C57BL/6 animals. Moreover, the highest proportions of Leydig cells and macrophages were noticed in Swiss mice, which may indicate increased testosterone levels. Altogether, such observations must be taken into account when choosing any of the studied strains for reproduction studies.

Intermediality, Narrative Texts, and Digitally Mediated Tasks in the EFL Classroom
Authors: Caruso Celestine , Hofmann Judith
Published: August 2021

In our paper, we propose that intermediality and participatory culture are intertwined concepts that are both part of the digital world. By using Task-Based Language Teaching (TBLT) as a pedagogical framework, we argue that digitally mediated tasks can be beneficial for the EFL classroom while at the same time including aspects of intermediality and participatory culture. In the last part of the paper, we present task examples that tackle this issue and were tested in the EFL classroom.
Lendo o suspense transmidial de Poe

Published: August 2021

Este artigo apresenta uma reflexão quanto à aplicabilidade dos princípios da narratologia funcionalista ao estudo de narrativas em diferentes mídias. Primeiramente, apresentamos uma breve exposição das origens e dos conceitos fundantes dessa corrente dos estudos literários. A seguir, aplicamos seus postulados ao exame dos recursos empregados na criação de suspense nas obras de Edgar Allan Poe e de Alfred Hitchcock, demonstrando como a análise de estruturas narrativas qualifica a leitura crítica interpretativa. Evidencia-se, com isso, o potencial do instrumental narratológico funcionalista de subsidiar práticas de ensino literário e de letramento intermidiático e multimodal.

Este trabalho apresenta uma proposta de roteiro pedagógico que faz uso de role-playing games (RPGs) de mesa no ensino de literatura. Nesse tipo de jogo, se faz fundamental o processo de criação de personagens, considerando que o aventureiro criado reagirá a diversos tipos de situação. Ou seja, RPGs facilitam o exercício de pensar como um outro (no caso, o personagem criado), trabalhando assim questões relacionadas à criatividade e à empatia. Nossa proposta traz como exemplo a adaptação do romance Capitães da Areia para o formato de RPG de mesa, pedindo aos alunos que imaginem quais tipos de personagens e situações fariam sentido no contexto da obra. De tal maneira, os estudantes respondem ao texto lido, passando por um processo de retextualização e ocupando o espaço protagonista de autores. Os aportes teóricos incluem a Base Nacional Curricular Comum (BNCC) e estudos anteriores envolvendo o uso de RPGs no ensino.
Narrativa transmídia
Authors: Falcão Barbara
Published: August 2021

No presente artigo, apresentamos os resultados de uma pesquisa-ação que propõe o uso da Narrativa Transmídia para o ensino de língua portuguesa no Ensino Fundamental. A aplicação pedagógica da Narrativa Transmídia pode oferecer estratégias para a criação de atividades que permitam aos estudantes desenvolver habilidades relacionadas aos multiletramentos, conceito proposto pelo Grupo Nova Londres (1996) e preconizados pela BNCC. A análise do processo e do produto final da narrativa transmídia produzida por estudantes de uma escola pública da capital paulista indica que a aplicação pedagógica da Narrativa Transmídia pode mobilizar, de modo coordenado e significativo, conhecimentos acerca da tipologia textual narrativa (ADAM, 2019) e sobre a cultura digital, além de desenvolver habilidades de escrita e leitura sobre os mais variados gêneros textuais (BAKHTIN, 1997), promovendo o protagonismo e a criticidade dos estudantes por meio de atividades coletivas e colaborativas.

Authors: Oliveira Priscila Almeida , Silva Priscila de Lima
Published: August 2021

A disponibilidade de geotecnologias tem estimulado a produção e o consumo de informações espaciais, aumentando a necessidade de validações para garantir a qualidade cartográfica. Este artigo tem como objetivo avaliar a aplicação de imagens do satélite Sentinel-2, que podem ser obtidas sem custos e em forma de mosaico temporal pela plataforma Google Earth Engine (GEE), para atualização da Base Cartográfica Contínua na escala de 1:100.000 (BC100) do Instituto Brasileiro de Geografia e Estatística (IBGE). Foi avaliada a acurácia posicional planimétrica, tomando como referência um ortomosaico do IBGE, com resolução espacial de 1 m, utilizou-se o método de feições lineares Buffer Duplo. Foram analisadas as vias da Universidade Federal Rural do Rio de Janeiro (UFRRJ), campus Seropédica, as quais foram vetorizadas na imagem de referência e no mosaico em teste. Em seguida foram avaliadas as discrepâncias obtidas, considerando o Padrão de Exatidão Cartográfica para Produtos Cartográficos Digitais (PEC-PCD) e o Erro Padrão (EP), para escala 1:100.000, obteve-se como resultado classe A. A aprovação do mosaico temporal formado por pixels de dias diferentes, disponibilizado pelo GEE, motivou a validação dos arquivos brutos e do mosaico obtido pela plataforma Sentinel Hub (EO Browser), ambos formados por pixels do mesmo dia. Aplicou-se a Análise de Variância (ANOVA) para comparar as discrepâncias entre as imagens e concluiu-se que estatisticamente não há diferenças. Mostrando que para a área de estudo, analisando as vias, as imagens brutas do Sentinel-2, o mosaico temporal GEE e mosaico Sentinel Hub são aplicáveis para a atualização da BC100.
Análise da Variabilidade Espaço-temporal da Topografia do Nível "Médio" do Mar a partir de Dados de Altimetria por Satélites e Estações da Rede Maregráfica Permanente para Geodésia
Authors: Souza Larissa Messias , Ferreira Ítalo Oliveira
Published: August 2021

A técnica comumente aplicada para mensurar as variações locais do Nível “Médio” do Mar (NMM) e consequentemente da Topografia do Nível “Médio” do Mar (TNMM), têm sido a partir de uma abordagem geodésica, em que marégrafos são instalados na costa oceânica. No entanto, devido as dificuldades na manutenção de longas séries temporais, seja pela falta de recursos financeiros para instalação ou dificuldades técnicas para a instalação de marégrafos ou réguas linimétricas, vê-se como alternativa o emprego de dados por satélites altimétricos (ALTSAT). Diante disso, o presente estudo tem como objetivo propor uma metodologia para analisar as variações mensais da TNMM a partir de dados (ALTSAT) e de maregrafia, para este propósito, foi utilizada a missão CryoSat-2 (CS2) e os dados de maregrafia das estações EMFOR, EMSAL e EMIMB, todas pertencentes à Rede de Monitoramento Permanente para Geodésia (RMPG) no período de fevereiro de 2011 a setembro de 2019.  Os resultados demostraram que a metodologia proposta é viável e pode ser empregada como complemento em dados maregráficos. Numa análise comparativa das variações locais da TNMM, verifica-se, no geral, que houve uma variação mais acentuada nos dados de maregrafia ao serem comparados com a ALTSAT, tal comportamento foi visível em todas as estações utilizadas, exceto em EMIMB, que apresentou maiores variações mensais na técnica de ALTSAT. Apesar do exposto, os resultados foram satisfatórios, explicitando uma discrepância anual entre as técnicas em todas as estações maregráficas na casa dos milímetros.

Published: August 2021

O presente artigo propõe realizar uma articulação entre bibliografias referentes às temáticas acerca do Planejamento em Políticas Públicas de Educação e o Desenvolvimento Humano a partir da Teoria Histórico-Cultural, sobretudo a dimensão da imaginação e criação. Para isso, relacionamos os conceitos de trabalho, atividade criadora, produção imaginária e planejamento, destacando as aproximações desses conceitos e a relevância deles para a elaboração de Políticas Públicas em Educação que tenham como foco o coletivo. Acreditamos que a inadaptação faz com que os sujeitos mobilizem potências criadoras e que o planejamento tem relação com esse processo, pois pressupõe desenhos de futuro que, se críticos, podem articular coletivos e contribuir com a transformação da realidade e emancipação humana.
A (QUASE) invisibilidade da Educação de Jovens e Adultos na Política Nacional de Alfabetização
Authors: Silva Jaqueline Luzia da
Published: August 2021

O presente artigo tem como principal objetivo refletir e analisar a atual Política Nacional de Alfabetização (PNA), instituída em 2019, especificamente no que se refere à Educação de Jovens e Adultos (EJA). A metodologia que embasa o estudo é uma investigação documental, de natureza qualitativa, do período compreendido entre os anos de 2003 e 2019, referindo-se também às legislações anteriores que dizem respeito à EJA. O referencial teórico baseia-se nos estudos de Freire (1999); Maciel e Resende (2019); Albuquerque, Morais e Ferreira (2013), dentre outros. As principais conclusões do trabalho reconhecem que a PNA invisibiliza a EJA oferecida aos sujeitos pouco ou não escolarizados, ao mesmo tempo que propõe uma prática equivocada para a ação pedagógica alfabetizadora.

A alfabetização no Brasil constitui um campo de conflitos e disputas entre diversas áreas de conhecimentos, como história, psicologia, sociologia e linguística. Segundo dados divulgados pela Pesquisa Nacional por Amostra de Domicílios (PNAD) Contínua – Educação em 2020, nosso país ainda possui uma média de 11 milhões de analfabetos (TOKARNIA, 2020). Essa realidade não demonstra uma falta de avanços em relação aos estudos na área, e sim que, na maior parte da história da alfabetização, as políticas públicas brasileiras têm sofrido retrocessos em virtude da descontinuidade na alternância de poder, o que incide em fragmentação e/ou rupturas de ações públicas – tal fato reverbera diretamente na formação e na prática docente. Diante disso, este dossiê, intitulado “Diálogos sobre alfabetização: das políticas públicas ao cotidiano escolar” foi planejado como forma de resistência às políticas atuais de alfabetização, em especial, ao Decreto n. 9.765 (BRASIL, 2019), publicado no governo de Jair Messias Bolsonaro, que institui a Política Nacional de Alfabetização (PNA).

"Todos os rios levam a sua boca"
Authors: Baltazar Mattos Marina , Silveira Ribeiro Gustavo
Published: August 2021

Em um convite à viagem, este ensaio procura pensar o nomadismo inquieto de José Leonilson, e como suas relações de enraizamento ou deslocamentos com o espaço produziam sentidos de pertencimento e habitavam suas obras poéticas em constante movimentação entre o dentro e o fora, geografias afetivas e corporais, realidades e ficções. Para isso, o norte será pensar o porquê de sua única obra a céu aberto se encontrar em sua cidade natal, o sul os movimentos de pessoas e de linguagens, para a tentativa de entendimento do Nordeste como lugar de falta, revolta ou saudade, e as geografias enquanto cartografias pessoais e corporais, até se chegar ao leste, onde o “quarto de costura” será visto como paradigma e, a oeste, um amontoado de cadernos de viagens que carregam impulsos estéticos e experimentos de vida, pessoas, impressões e sonhos que fazem Leonilson querer carregar o mundo nas costas, ou, ao menos, em suas obras. Cidadão do mundo, fazia da sua arte sua bagagem.

Background: Chronic Obstructive Pulmonary Disease (COPD) working group in 2002 reported that 12 Asia Pacific countries showed the prevalence of COPD in Indonesia was 5.6%. Based on medical record data at the Bima Regional General Hospital in April - September 2017, the number of COPD cases was 15 people. COPD is a disease characterized by progressive airway limitation caused by abnormal inflammation with general symptoms of worsening shortness of breath and decreased SpO2. To overcome this, provide breathing retraining which is a technique used to compensate for respiratory deficiencies. Objective: To determine the effect of breathing retreaning on increasing SpO2 in COPD patients. Methods: Quasi Experimental research design using One Group Pretest Posttest Design with a total sample of 17 respondents. Statistical test using Paired T-Test. The data collected is in the form of respondent's characteristic data, looking at the SpO2 value before and after being given breathing training. Respondents who were given the breathing retraining intervention before and after the intervention were measured using a questionnaire.

Pro-inflammatory cytokine polymorphisms like Tumor Necrosis Factor- (TNF), has been found associated to severe depressive disorder (MDD). The Pro-inflammatory cytokines tumor necrosis factor (TNF-α) G-308A (rs1800629) have been discovered to have an important role in the pathophysiology of depressive disorders and the mechanism of antidepressant treatment. The present study aims to study TNF-α gene polymorphisms in Major depressive disorder using allele specific PCR. The results show that family history are non- significant different between patients and control group (0.6346) and also there was non- significant different in BMI (0.3417), The genotyping data show tow alleles and three genotyping (AG, GG, AA) the statically analysis show non-significant differences between patients and controls groups (0.095, 0.800) for GG, AA and GA respectively with more frequent of GA in patients than control group, the G allele was less frequent in patient than control while A allele was more frequent in patients than control group in significant differences (0.0001). It can be concluded that TNF genotyping didn’t impact in the Major depressive disorder but the allele distribution may have potential role in MDD patients.

Published: August 2021

Carpal tunnel syndrome is a neurological disease that presented with paresthesias, pain, and numbness in the hand's median nerve compression. Vitamin D was assumed to affect both electrophysiological &clinical gradings, the study aims to assess the correlation between the deficiency of vitamin D and both electrophysiological and clinical gradings. This study was conducted in Ghazi Alhariri Hospital during the period from the first of November/2020 to the twenty-eighth of February/2021, fifty five individuals were referred to as Carpal tunnel syndrome patients, and compared to (55) control individuals, blood samples were withdrawn from the patients (3ml), centrifuged and kept in the freezer (-20°C) until the time of analysis of vitamin D3, Sensory and motor nerve conduction studies of both median and ulnar nerve were done bilaterally. patients were classified electrophysiologically and clinically into two subgroups (mild to moderate) and (severe) groups. The result showed that the differences are not significant in the gender, BMI and vitamin D of the patients versus the control group (p>0.05), the difference of the electrophysiological parameters was not significant between patients with low vitamin D versus those with normal vitamin D (p value>0.05), there was a significant association between the electrophysiological and clinical grading in addition to a significant association between vitamin D level and the clinical grading. Vitamin D deficiency does not affect the electrophysiological parameters while the clinical grading becomes worse with the decrease in its level. The electrophysiological grading is associated with clinical grading.

Published: August 2021

Parkinson’s disease is one among the most common neurological disorder that is increasing day by day. Parkinson’s disease could become more dangerous in not treated well in time. Hence, early and automated detection of Parkinson’s disease is greatly essential. In current research, five classifiers such as DT, NB, NN, RF and SVM are exploited for PD detection. Nonetheless, more time is greatly necessitated for using further classifiers for PD detection. Enhanced Convolutional Neural Network (ECNN) method is greatly suggested for mitigating this issue in PD detection. Primarily, input PD dataset processing is done as preprocessing steps for validating dataset quality to accomplish the process. On the basis of Multiple Feature Evaluation Approach (MFEA), feature assessment processing is done which comprises quite a lot of feature assessment and ranking algorithms to weight features worth and features set extraction. Furthermore, a feature selection model by principal component analysis is suggested for classifier accuracy improvement. To conclude, Enhanced Convolutional Neural Network (ECNN) training is done over these certain features for PD detection, besides its performance evaluation is done through various metrics.

Published: August 2021

The objective of this article is to study the linguistic adaptation that accompanies the introduction and modification of a type of lawsuit originating in another legal system: the case of class action. In the context of the study of the comparative neology of French, Polish and Czech, considered in particular from the angle of borrowing and its equivalents, it is interesting to explore the adoption and linguistic adaptation of a legal concept. The one selected for this study is the American class action, which has already been the subject of a linguistic analysis focusing on French in France and French-speaking countries, and in Spain and Italy. The present study therefore extends the research carried out so far to the cases of Czech and Polish while updating the data on French.
Can multi-stakeholder forums mediate indigenous rights and development priorities? Insights from the Peruvian Amazon
Authors: Rodriguez D. , Barletti J.P. Sarmiento
Published: August 2021

The protection of indigenous peoples in isolation and initial contact (PIACI) is one of the most complex issues in the human rights and environmental agenda. The implementation of frameworks to protect PIACI involves addressing conflicts by the advance of public and private initiatives
and interests in their territories. This paper focuses on PIACI Roundtable, a multi-stakeholder forum (MSF) established in Peru's Loreto region to contribute to protecting these groups. The MSF sought to address the long-standing delays in the creation of five Indigenous Reserves for PIACI
in Loreto's forests. The paper argues that MSFs may be fruitful spaces to raise awareness of the rights of vulnerable peoples and coordinate the implementation of supporting actions, but only when participants hold a shared respect for those recognised rights. If not, MSFs may become spaces
where powerful actors relegate recognised rights to a perspective among others.

Objetivos

La adulteración de una muestra de orina por parte de un paciente puede pasar inadvertida si no se realiza una prueba de validez de la muestra. En este estudio se ha comparado el método análisis de densidad (SG, según acrónimo inglés), pH, la tira para detección de adulterantes TECO™ (Dipstick) y el análisis de oxidantes, para determinar las diferencias entre los mismos y permitir una toma de decisiones informada, a la hora de seleccionar un método.

Métodos

El análisis de la creatinina, la SG y el pH es esencial a la hora de realizar una prueba de validez de la muestra. Se compararon los métodos químicos automáticos de análisis de SG y pH con la potenciometría para el análisis de pH, la refractometría para el análisis de SG, y el método dipstick. Así mismo, se realizó una comparación entre el análisis de oxidantes y el método Dipstick.

Resultados

Se observó una concordancia del 81,9% y del 64,7% entre el método químico de análisis de SG y la refractometría y el método Dipstick, respectivamente. La concordancia entre la refractometría y Dipstick fue del 66,1%. La concordancia entre el método químico de análisis del pH y la potenciometría y el método Dipstick fue del 74,3% y del 81,4%, respectivamente. La concordancia entre la potenciometría y el método Dipstick fue del 85,7%. El análisis de resultados se realizó mediante el método de regresión de Deming y la prueba F. Los resultados demuestran una mejor correlación entre el método químico de análisis de SG y la refractometría, que con el método Dipstick. El análisis de oxidantes mostró una buena correlación con Dipstick a la hora de detectar adulterantes como el clorocromato de piridinio, el nitrito y la lejía.

Conclusiones

Se observaron diferencias en la medición de SG y pH. Dichas diferencias se deben tanto a factores metodológicos como instrumentales. Se recomienda el empleo de métodos químicos automatizados, así como del análisis de oxidantes debido a sus consistencia, precisión y mejor tiempo de respuesta para realizar la prueba de validez de la muestra para detectar la presencia de drogas.
