A Time-Varying Distributed Unit Hydrograph considering soil moisture content
Authors: Yi Bin , Chen Lu , Zhang Hansong , Jiang Ping , Liu Yizhuo , Qiu Hongya
Published: September 2021

Abstract. The distributed unit hydrograph (DUH) method has been widely used for flood routing simulation, because it can well characterize the underlying surface characteristics and various rainfall intensities. The core of the DUH is the calculation of flow velocity. However, the current velocity formula assumed a global equilibrium of the watershed and ignored the impact of time-varying soil moisture content on flow velocity, which leads to a larger flow velocity value. The goal of this study is to identify a soil moisture content factor, which was derived based on the water storage capacity curve, to explore the responses of DUH to soil moisture content in unsaturated areas. Thus, an improved distributed unit hydrograph based on time-varying soil moisture content was proposed in this paper. The proposed method considered the impact of both the time-varying rainfall intensity and soil moisture content on the flow velocity, and the watershed is assumed not to be equilibrium but vary with the soil moisture. The Qin River Basin was selected as a case study, and results of the time-varying distributed unit hydrograph (TDUH) and current DUH methods were used as comparisons with that of proposed method. Influence mechanism of time-varying soil moisture content on the flow velocity and flood forecasts were explored. Results show that the proposed method performs the best among the three methods. The shape and duration of the unit hydrograph can be mainly related to the soil moisture content at initial stage of a storm. When the watershed is approximately saturated, the grid flow velocity is majorly dominated by the excess rainfall.
Reconstructing climate trends adds skills to seasonal reference crop evapotranspiration forecasting

Published: September 2021

Abstract. Evapotranspiration plays an important role in the terrestrial water cycle. Reference crop evapotranspiration (ETo) has been widely used to estimate water transfer from vegetation surface to the atmosphere. Seasonal ETo forecasting provides valuable information for effective water resource management and planning. Climate forecasts from General Circulation Models (GCMs) have been increasingly used to produce seasonal ETo forecasts. Statistical calibration plays a critical role in correcting bias and dispersion errors in ETo forecasts. However, time-dependent errors, resulting from GCM’s misrepresentations of climate trends, have not been explicitly corrected in ETo forecast calibrations. We hypothesize that reconstructing climate trends through statistical calibration will add extra skills to seasonal ETo forecasts. To test this hypothesis, we calibrate raw seasonal ETo forecasts constructed with climate forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) SEAS5 model across Australia, using the recently developed Bayesian Joint Probability trend-aware (BJP-ti) model. Raw ETo forecasts demonstrate significant inconsistencies with observations in both magnitudes and spatial patterns of temporal trends, particularly at long lead times. The BJP-ti model effectively corrects misrepresented trends and reconstructs the observed trends in calibrated forecasts. Improving trends through statistical calibration increases the correlation coefficient between calibrated forecasts and observations (r) by up to 0.25 and improves the continuous ranked probability score (CRPS) skill score by up to 15 % in regions where climate trends are misrepresented by raw forecasts. Skillful ETo forecasts produced in this study could be used for streamflow forecasting, modelling of soil moisture dynamics, and irrigation water management. This investigation confirms the necessity of reconstructing climate trends in GCM-based seasonal ETo forecasts, and provides an effective tool for addressing this need. We anticipate that future GCM-based seasonal ETo forecasting will benefit from correcting time-dependent errors through trend reconstruction.

Abstract. The snow cover spatial variability in mountainous terrain changes considerably over the course of a snow season. In this context, fractional snow-covered area (fSCA) is an essential model parameter characterizing how much ground surface in a grid cell is currently covered by snow. We present a seasonal fSCA algorithm using a recent scale-independent fSCA parameterization. For the seasonal implementation, we track snow depth (HS) and snow water equivalent (SWE) and account for several alternating accumulation–ablation phases. Besides tracking HS and SWE, the seasonal fSCA algorithm only requires subgrid terrain parameters from a fine-scale summer digital elevation model. We implemented the new algorithm in a multilayer energy balance snow cover model. To evaluate the spatiotemporal changes in modeled fSCA, we compiled three independent fSCA data sets derived from airborne-acquired fine-scale HS data and from satellite and terrestrial imagery. Overall, modeled daily 1 km fSCA values had normalized root mean square errors of 7 %, 12 % and 21 % for the three data sets, and some seasonal trends were identified. Comparing our algorithm performances to the performances of the CLM5.0 fSCA algorithm implemented in the multilayer snow cover model demonstrated that our full seasonal fSCA algorithm better represented seasonal trends. Overall, the results suggest that our seasonal fSCA algorithm can be applied in other geographic regions by any snow model application.
4-H Youth Volunteer Retention in Science Projects
Authors: Del Bianco Veronica , Cater Melissa , Fox Janet
Published: September 2021

Retention of volunteers and participants is a critical concern for programs that rely on their manpower, but limited empirical research exists, especially on youth volunteers. This descriptive, cross-sectional quantitative study examined the influence of volunteer motivation, participation, and science project type on the retention of 4-H youth volunteers ages 12 to 19 years participating in science projects in 3 states. An instrument was created for this study that included both existing survey scales and researcher-developed items based on combined research from the citizen science, volunteer development, and youth development fields. The research revealed that consistency and engagement were correlated with the predictors of retention, but race was not. 4-H science programs have a significantly higher likelihood of retaining youth participants than 4-H citizen science programs. Suggestions for youth educators to develop retention strategies are discussed based on the findings and future research into youth volunteer engagement is proposed.

Published: September 2021

LGBTQ+ youth experience health disparities compared with heterosexual and cisgender youth. Community-based, positive youth development organizations are an important resource to support and affirm LGBTQ+ youth. This study aimed to identify the opportunities and challenges in supporting LGBTQ+ youth within 4-H. The study took place in one state in the United States within a 4-H program and employed qualitative, community-based methods using SWOT (strengths, weaknesses, opportunities, threats) analyses and focus groups of 4-H staff, support staff, volunteers, and youth participants. The majority of participants were White and middle class with direct connections to the 4-H program. Thematic analyses were conducted by multiple analysts until consensus was reached. Challenges and opportunities emerged in 3 themes: (a) organizational climate; (b) policies and procedures; and (c) training, education, and resources. Two additional themes included opportunities only: (a) community engagement and (b) youth-specific resources. This study has important implications for the 4-H program, rural community practice, and research, including strategies to improve LGBTQ+ inclusivity through education, programs and policies, hiring, and community partnerships. Additionally, this study highlights the opportunity and unique positionality of the 4-H program to amplify youth voices in the creation of youth-specific resources.

Authors: Garst Barry A. , Pann James , Berry Tiffany , Biesecker Gretchen , Spector Jason , Conn Michael , Jones Curtis
Published: September 2021

Youth-serving organizations seek effective and cost-efficient solutions to build evidence and advance their impact. Some common challenges include choosing data systems or assessments, budgeting and planning for 3rd-party studies, and refining measurement and outcomes when programs expand or change. Evaluation advisory boards (EABs) are a low-cost solution to add evaluation capacity and can be mutually beneficial to both youth-serving organizations and evaluation experts. Previous research suggests that EABs may encourage meaningful use of data, support internal evaluators, and/or facilitate difficult conversations among stakeholders. However, there are very few examples of successful EABs in practice. This paper shares the perspectives of EAB members and organizational evaluation leaders from a large national after-school program, After-School All-Stars (ASAS), including (a) a description of the benefits of EABs, (b) how EABs may be especially helpful with the context of the COVID-19 pandemic, and (c) examples of youth-serving organizations’ EABs. The experiences and lessons learned by ASAS and its EAB are generalizable to other non-profit youth development programs. Recommendations for structuring EABs based on organizational goals are provided.

APPROACHING THE BORDERLANDS OF STATISTICS AND MATHEMATICS IN THE CLASSROOM: QUALITATIVE ANALYSIS ENGENDERING AN UNEXPECTED JOURNEY
Authors: WATSON JANE M. , NATHAN ERICA L.
Published: September 2021

To capture aspects of pedagogical content knowledge (PCK) not illuminated in an earlier written survey, an interview protocol was used with 40 middle school teachers. The scenarios were intended to elicit teachers’ understanding of the big ideas, ability to anticipate students’ answers, and intervention strategies for the classroom. This was expected to be a straight-forward journey based on teachers’ responses to three context-based scenarios regarding students’ answers to questions. Instead we were surprised by teachers’ responses that revealed their perceptions that their experiences teaching mathematics and teaching statistics are very different. This led to further analysis of the PCK tasks and a suggestion that the mathematics embedded in the tasks was sometimes an impediment for the teachers, especially in relation to intervention strategies in the classroom.

ON CONCEPTUAL ANALYSIS AS THE PRIMARY QUALITATIVE APPROACH TO STATISTICS EDUCATION RESEARCH IN PSYCHOLOGY
Authors: PETOCZ AGNES , NEWBERY GLENN
Published: September 2021

Statistics education in psychology often falls disappointingly short of its goals. The increasing use of qualitative approaches in statistics education research has extended and enriched our understanding of statistical cognition processes, and thus facilitated improvements in statistical education and practices. Yet conceptual analysis, a fundamental part of the scientific method and arguably the primary qualitative method insofar as it is logically prior and equally applicable to all other empirical research methods—quantitative, qualitative, and mixed—has been largely overlooked. In this paper we present the case for this approach, and then report results from a conceptual analysis of statistics education in psychology. The results highlight a number of major problems that have received little attention in standard statistics education research.

Authors: Blanco Ruiz Mónica , Pérez Serrano Mercedes
Published: September 2021

El objetivo de este artículo es analizar la expresión de la emoción en narraciones autobiográficas orales en español como lengua extranjera de 20 arabófonos. Se usaron tres fragmentos de películas que inducían alegría, tristeza y uno neutro. Los informantes rellenaron un cuestionario donde aseguraban haber sentido dichas emociones y narraron acontecimientos donde habían experimentado alegría y tristeza. Analizamos el léxico, centrándonos en la complejidad –densidad, diversidad y sofisticación–, vocabulario emocional y las categorías gramaticales usadas para expresar emoción. No hubo diferencias significativas en la complejidad léxica, hubo más palabras positivas que negativas -especialmente verbos, seguidos de sustantivos, adjetivos y adverbios- en ambos discursos, más palabras negativas en el discurso de tristeza que negativas en el de alegría y más palabras sofisticadas positivas. Los resultados revelan la importancia del vocabulario emocional en la enseñanza para mejorar la socialización y aculturación del lenguaje dados los diferentes guiones emocionales entre culturas e idiomas
The Use of the Progressive in Light of the AH in Monolingual EFL-Instructed Spanish Learners at University Level: A Longitudinal Learner Corpus-Based SLA Study
Authors: Díez-Bedmar María Belén
Published: September 2021

Despite recent interest in the analysis of the progressive in light of the Aspect Hypothesis (AH), little information is available on the use of the progressive by EFL Spanish learners. To gain a better understanding of the use of the progressive in EFL-instructed Spanish learner writing at advanced levels, this longitudinal learner corpus-based SLA study examines the frequency of use of the progressive, as well as two of the associations of the AH: (i) the progressive with dynamic verbs; (ii) and, no overextension of the progressive to stative verbs. The effects derived from factors or variables such as the tense employed, target- and non-target-like uses, students’ academic year and expected higher proficiency level, task type and individual preferences are also discussed as a way to fine-tuning the strong version of the AH to the use of the progressive by this learner group

Evolución cultural en sociedades artificiales
Authors: Sterpin Buitrago Dante Giovanni
Published: September 2021

En este artículo se revisan las generalidades de algunos modelos computacionales inspirados en características propias de la evolución cultural y se clasifican en dos grupos, según se fundamenten o no en la memética. Se pretende demostrar, a pesar del auge que han tenido en aplicaciones orien­tadas a solucionar problemas de optimización, su falta de naturalidad frente a la posibilidad de simular características culturales presentes en las sociedades naturales. La cultura se asume como el conjunto de ideas y comportamientos desarrollados y transmitidos mediante la interacción entre agentes portadores de genes y memes, pues se considera que estos tienen genéticamente codificada una maquinaria biológica con cierto sistema mental y que en este sistema están los memes capaces de comunicarse con otros agentes semejantes. Independientemente del hecho de tener neuronas en este sistema, en la mayoría de los modelos acá revisados no hay una relación genético-cultural de este tipo, pues en ellos lo cultural queda reducido a acelerar la resolución genética de problemas; o, en el mejor caso encontrado, lo cultural emplea memes derivados de los genes, pero como copias de su información génica

Ultrasonography is a safe and effective method of diagnosing early pregnancy and determining the position of the gravid uterus. In our study, 2080 pregnant women with amenorrhea for three months and a positive pregnancy test were chosen. The study was conducted in the Radiology & Imaging department of Failaria & General Hospital from Jan 2016 to Dec 2019. The objective of our study is to investigate the Sonographic findings of first trimester pregnancies detecting the retroverted gravid uterus, normal, abnormal and complicated pregnancies. In the present study out of 2080 pregnancies, we found uterus retroverted in about 7% of women and only one case of acute retention of urine due to retroverted gravid uterus. Here, the majority of pregnant women were 20-24 years of age, which is 980 (47.12%) and 150 (7.21%) women pregnant at the age of over 35 years. In our study, 190 (9.13%) of the 2080 pregnancies with sonographic diagnosis were fetal losses. The diagnosis of early normal intrauterine pregnancy (IUP) was 1890 (90.87%), Incomplete abortion 95 (4.57%), Missed abortion 35 (1.68%), Blighted ovum 39 (1.88%), ectopic pregnancy 14 (0.67%) and Hydatiform mole 7 (0.34%) cases.

Published: September 2021

Tomato fruit ripening is a purely natural process but it can also be influenced by several artificial means such as using Nordox 75 WG. In recent times, artificial tomato ripening has been an issue because of its health implications. To get a detailed understanding of the hazards, tomatoes treated with the chemical and those that did not undergo any chemical treatment were harvested and analyzed. On analysis, different compounds were found to be associated with tomatoes treated with Nordox 75 WG. The main objective of the paper was to identify the components of the chemical. Untreated Nordox 75 WG tomatoes recorded a 0g/L Cu2+ and K recorded the highest value of 0.23 mg/g. Tomatoes treated with Nordox 75 WG recorded 0.76 g/L Cu2+ and Ca2+with a least value of 0.003 mg/g. The conventional way of ripening is not uniform and results mostly in a shorter lifespan. Various strong chemicals are used for this process

Published: September 2021

n recent time several imaging modalities have been implicated for diagnosing periapical lesion. The present study is carried out to determine and compare the nature and extent of periapical lesions using conventional radiography, digital radiography, and ultrasound imaging and to confirm the diagnosis with histopathological examination. Thirty patients aged between 15 and 45 years with well-defined periapical radiolucency associated with anterior maxillary or mandibular teeth requiring endodontic surgery or extraction were selected. The pre-operative intraoral periapical radiographs and digital images and were diagnosed by three observers. Ultrasound examination was performed, and the images were assessed by an ultra-sonographer. The periapical tissues were obtained to enable histopathological investigation. The data was statistically analyzed using the kappa procedure, Kruskal Wallis Anova& Mann-Whitney U test. Results showed that the percentage accuracy of diagnosing periapical lesions using conventional radio- graphy, digital radiography and ultrasound was 86.67%, 93.33% & 93.33% respectively. Thus, we conclude that ultrasound helps in distinguishing between periapical granuloma and cyst which is of importance in predicting the treatment outcome.
STEAM e design thinking: ferramentas transdisciplinares no ensino de inglês

Published: September 2021

O presente artigo tem a finalidade de refletir sobre como a aplicação do conceito STEAM (Science, Technology, Engineering, Arts and Maths) e do design thinking na sala de aula pode contribuir para um

ensino de língua inglesa transdisciplinar. Incorporando, de forma transdisciplinar, os saberes da Ciências, Tecnologia, Engenharia, Artes e Matemática, o STEAM é uma proposta de ensino globalizadora, baseada

em projetos, que relaciona os conteúdos disciplinares, a partir de problemas reais, para que, integrados à estrutura de conhecimento do indivíduo, assumam significado em uma situação concreta. A implementação de atividades em sala de aula utilizando a abordagem STEAM é um desafio para professores de línguas, uma vez que se inspira na metodologia do design thinking e é baseado em cinco formas interconectadas de conhecimento: autoconhecimento cultural, conhecimento relacional, conhecimento crítico, conhecimento visionário e ético, e conhecimento em ação. Ao final das aulas, pôde-se perceber que os alunos enriqueceram seus conhecimentos não só específicos da disciplina de língua inglesa, mas em diversas outras áreas, como história, arte, design e geografia.

O estudo envolve a inserção de temas relacionados à Astronomia no ensino fundamental a partir de perspectivas teóricas que primam pelas relações sociais e favoreçam a construção dos conceitos dentro de

um processo dialético. O estudo parte do questionamento referente a que elementos são favorecidos em uma prática pedagógica sociointeracionista, tendo como objetivo analisar as potencialidades de um ensino pautado pela perspectiva sociointeracionista. Para tanto, foi estruturada uma sequência didática apoiada em questionamentos de forma a proporcionar a interação, o diálogo e a participação dos estudantes. A aplicação ocorreu em uma turma de sexto ano, em uma escola pública estadual no interior do Rio Grande Sul. A investigação tomou como instrumento o diário de bordo preenchido pela pesquisadora que assumiu a condição de professora da turma. Os dados obtidos foram analisados à luz dos processos de interação social, estabelecendo como categorias de análise: interação aluno/aluno, aluno/professor e aluno/material. Tais resultados apontam, na primeira categoria, que os estudantes puderam interagir de forma plena com seus pares, possibilitando uma interlocução e um diálogo voltados a trocas e construção de saberes; na segunda categoria, mostraram que os estudantes tiveram oportunidade e liberdade de interagir com a professora/pesquisadora de modo a fazer inferências e questionamentos que enriqueceram suas aprendizagens; e, na terceira categoria, evidenciaram a importância de utilizar materiais didáticos voltados à realidade de cada turma, trazendo elementos que possibilitam resgatar seus conhecimentos espontâneos e contextualizados com sua cultura. A conclusão do estudo aponta para o fato de os processos de interações favorecerem a dimensão cognição-afeto, ampliando as possibilidades de aprendizagem.
O Pacto pela Alfabetização na Idade Certa em Goiás – PNAIC: A Formação em Serviço e seus Desafios
Authors: Silva Faria Edna , Alves Amone Inacia
Published: September 2021

Este trabalho resulta da reflexão sobre formação realizada em Goiás, intitulada: Pacto pela Alfabetização na Idade Certa – PNAIC. Essa proposta adveio em 2013, de uma expectativa do Ministério da Educação e

Cultura (MEC) em qualificar professores atuantes no ciclo de alfabetização, de modo que fossem capazes de refletir sobre os conceitos, práticas e significados do processo de alfabetizar, contribuindo para um

debate de âmbito nacional. No Brasil, a formação de professores alfabetizadores ainda é pífia, impactando sobretudo nos resultados demonstrados. Em Goiás, esse Programa foi responsável pela qualificação de

quatorze mil professores alfabetizadores, coordenadores e demais profissionais escolares. Compreendeu-se que, sem o investimento dessa ação, não seria possível a inserção dos alfabetizadores na discussão e na implementação de novas práticas e metodologias. Neste texto, adotando como metodologia a revisão bibliográfica, refletimos como o esclarecimento contribuiu para esse processo, ressaltando o papel da

interdisciplinaridade. O Programa utilizou material elaborado especificamente para o PNAIC, portanto este artigo aborda também a perspectiva de interdisciplinaridade adotada na elaboração dos materiais de suporte – os cadernos do PNAIC – e nos materiais de apoio – caixa de jogos e atividades – adotados como auxílio no processo de formação.
Prática pedagógica na perspectiva da complexidade: articulação entre educação matemática e educação para a vida
Authors: Guérios Ettiène
Published: September 2021

O objetivo deste artigo é refletir sobre a prática pedagógica, vinculada a princípios educativos. Tem-se como pressuposto que a docência em matemática, em uma perspectiva de complexidade, pode colaborar para a promoção da autonomia, da cidadania e da justiça social. A abordagem teórica está assentada em dois eixos: educação para a cidadania, como processo educativo para a vida; educação matemática, como educação para a vida. O objeto de reflexão é a prática pedagógica em matemática de uma professora, em sua turma de 7ª ano do Ensino Fundamental, em uma escola pública do município de Curitiba. A perspectiva da reflexão está assentada em ideias da complexidade e da transdisciplinaridade. A criatividade é o elemento articulador. Para tal, foram extraídas atividades por ela desenvolvidas e analisadas, sob o ponto de vista da criatividade didática e da perspicácia da docente, da criação ao desenvolvimento em sala de aula. Sob o ponto de vista dos alunos, foram analisadas as repercussões na aprendizagem matemática e educativa, na compreensão do mundo, em perspectiva planetária. Conclui-se com a defesa de que a aprendizagem conceitual de conteúdos curriculares e a formação educativa constituem um binômio em que uma significa a outra, que por sua vez, são pertinentes para uma escola criativa e transformadora.
Práticas de aprendizagens integradoras no Ensino Superior como um direito de todos: análise das experiências de inclusão nos cursos de Psicologia na perspectiva da teoria da complexidade e da transdisciplinaridade

Published: September 2021

A pesquisa explicitada neste artigo teve como objetivo geral investigar as práticas pedagógicas desenvolvidas no curso de psicologia ofertado na Universidade Federal de Alagoas (UFAL) e suas aproximações com as Práticas de Aprendizagem Integradoras trazidas por Alves (2016) que contribuem para um processo inclusivo que compreenda o sujeito para além de sua dimensão cognitiva. Metodologicamente tratou-se de uma pesquisa de natureza qualitativa do tipo exploratória. Como instrumento de coleta de dados utilizou-se a entrevista estruturada no qual foi aplicada com os professores de psicologia da UFAL. Os dados foram tratados com fundamento no arcabouço da análise de conteúdo e interpretado sob a luz do referencial teórico da complexidade, da transdisciplinaridade e das práticas de aprendizagens integradoras e inclusivas (PAII). Os conteúdos emergentes nas falas dos sujeitos da pesquisa se aproximam das PAII, visto que compartilham da percepção do sujeito para além de uma única dimensão. Apesar disso, nota-se a necessidade de ampliar estudos que se voltem para essa temática. Por fim, percebemos a abertura dos profissionais entrevistados para conhecer novas formas de ensinar e aprender utilizando a criatividade como subsídio fundamental na construção do conhecimento. Isso nos permite pensar sobre a existência de uma dedicação para realizar práticas pedagógicas as quais superam as estratégias tradicionais de ensino.

Low costed and easily accessible laboratory parameters needed for predicting the prognosis of this disease as its outcome pattern vary greatly from patient to patient. There is promising data on predicting the outcomes with disnatremic results. Methods: In this study we retrospectively investigated all adults with the diagnosis of COVID-19 who attended to Turkan Ozilhan Hospital over a 3 months period. We evaluated the relation of dysnatremia (hyponatremia as <135 mmol/L or hypernatremia as >145 mmol/L) for need of intensive care unit (ICU) treatment, need of intubation for mechanic ventilatory support and inpatient mortality. Results: one thousand seventy tree patients with COVID-19 [53..9% males (793 patients) and 46.1% females (680 patients), were investigated for this study. Their median age was 53.9 years ranging betweent 19-94. The dysnatremic groups had significantly higher rates of need for ICU and intubation The need for ICU was 89 (21.5%) patients in normonatremic group but 38 (76%) patients in hypernatremic and 71 (64%) in hyponatremic patients (p<0.01 for each of them). The mortality rate was 5% in normonatremic patients but 50% in hypernatremic and 28% in hyponatremic patients (p<0.01 for each of them). Conclusion: In this study we aimed to draw attention to the importance of abnormal sodium levels as a predictive marker in COVID-19. In small town hospitals the physicians should be aware of the risks of disnatremic patients with COVID-19 and take precautions while treating them.
Screening of Diabetes in Pregnancy

Published: September 2021

The prevalence of gestational diabetes mellitus (GDM) is approximately 6% of pregnant women in the United States. The prevalence ranges is about from 2% to 38% worldwide and varies among racial-ethnic groups, often paralleling the prevalence of type 2 diabetes. The prevalence also varies due to differences in screening practices, population characteristics (eg, mean age and body mass index [BMI] of pregnant women), testing method, and diagnostic criteria. The prevalence is increasing over time, possibly due to increases in mean maternal age and weight, particularly with increasing obesity. In 2010, the International Association of Diabetes and Pregnancy Study Groups proposed new screening and diagnostic criteria for diabetes in pregnancy. Using these criteria, the global prevalence of hyperglycemia in pregnancy is estimated at 17%, with regional estimates ranging from 10% in North America to 25% in Southeast Asia. Different screening programs are carried out in different clinics, and all these differences lead to different results in the frequency of GDM. The criteria of the method and threshold value acceptance depends on the health policies of the countries, the experience of the clinicians and the characteristics of the patient population. In this review, we analyzed the methods recommended for GDM screening in pregnancy.

Objective: Febrile convulsions are the most frequent seizures in childhood. Pentraxin-3 is a new generation acute phase reactant that belongs to the family of long pentraxins. In our study, our primary aim was to investigate the difference in serum Pentraxin-3 levels between febrile convulsive patient group and non-convulsive fever control group. Our secondary aim was to evaluate the correlation between serum Pentraxin-3 levels and other more frequently used acute phase reactants (C-reactive protein, white blood cell count). Methods: Patients admitted to the pediatric emergency department between January 2014 and July 2014 were included in this prospective study The study included 35 febrile convulsive patients (patient group) and 35 non-convulsive febrile patients (control group) with similar age and gender, without chronic disease or ongoing medication brought to a university hospital Pediatric Emergency Department. Anamnesis information including active complaints, self and family history and laboratory findings of all cases included in the study were recorded on previously printed forms with demographic information such as age (month) and gender of the patient. In statistical analysis, the significance level was accepted as p <0,05. Results: There was no statistically significant difference between the groups in terms of age, gender, serum urea, creatinine, electrolytes, C-reactive protein and white blood cell counts (p>0,05). Serum Pentraxin-3 levels were 4,8±2,5 ng/ml in the patient group and 4.1±2.3 ng/ml in the control group. The difference between the two groups was not statistically significant (p>0,05). No correlation was found between Pentraxin-3 with C-reactive protein and white blood cell count. Conclusion: Our findings show that serum Pentraxine-3 levels are similar in patients with febrile convulsion and fever. In addition, it was concluded that Pentraxine-3 does not correlate with acute phase reactants, which are more commonly used.

Le Franc CFA : Quel avenir pour la monnaie en zone UEMOA ?
Authors: SOMAN Kouadio Daouda , SAID AHMED Djaffar Aboudou , BENTAHAR Hachemi
Published: September 2021

Cet article analyse la tournure de la coopération monétaire entre la France et ses anciennes colonies en cherchant à déterminer l’avenir du Franc CFA. En effet, le Franc CFA a suscité plusieurs débats et malgré les réformes institutionnelles mises en œuvre dans les années 1970, l’idée d’abandon de cette monnaie coloniale a été évoquée depuis 1983. Cependant, ce n’est que le 29 juin 2019 à Abuja (Nigéria) que le processus de la création d’une monnaie commune a été enclenché lors de la conclusion de la conférence des chefs d’Etat de la Communauté Economique des Etats de l’Afrique de l’Ouest (CEDEAO). Ainsi, « Eco » a été adopté comme le nom de la monnaie unique de la CEDEAO et devrait donc entrer en vigueur en 2020 dans les quinze États de l’espace CEDEAO. Toutefois, la mise en place de cette nouvelle monnaie ((Eco) a pris un grand retard mais son utilisation fera disparaître le Franc CFA et restreindra ou supprimera la coopération monétaire entre la France et les pays de l’UEMOA.

Backgrounds: To evaluate the predictive power of 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) derived radiomics in molecular subtype classification of breast cancer (BC). Methods: A total of 273 primary BC patients who underwent a 18F-FDG PET/CT imaging prior to any treatment were included in this retrospective study, and the values of five conventional PET parameters were calculated, including the maximum standardized uptake value (SUVmax), SUVmean, SUVpeak, metabolic tumor volume (MTV), and total lesion glycolysis (TLG). The ImageJ 1.50i software and METLAB package were used to delineate the contour of BC lesions and extract PET/CT derived radiomic features reflecting heterogeneity. Then, the least absolute shrinkage and selection operator (LASSO) algorithm was used to select optimal subsets of radiomic features and establish several corresponding radiomic signature models. The predictive powers of individual PET parameters and developed PET/CT derived radiomic signature models in molecular subtype classification of BC were evaluated by using receiver operating curves (ROCs) analyses with areas under the curve (AUCs) as the main outcomes. Results: All of the three SUV parameters but not MTV nor TLG were found to be significantly underrepresented in luminal and non-triple (TN) subgroups in comparison with corresponding non-luminal and TN subgroups. Whereas, no significant differences existed in all the five conventional PET parameters between human epidermal growth factor receptor 2+ (HER2+) and HER2– subgroups. Furthermore, all of the developed radiomic signature models correspondingly exhibited much more better performances than all the individual PET parameters in molecular subtype classification of BC, including luminal vs. non-luminal, HER2+ vs. HER2–, and TN vs. non-TN classification, with a mean value of 0.856, 0.818, and 0.888 for AUC. Conclusions: PET/CT derived radiomic signature models outperformed individual significant PET parameters in molecular subtype classification of BC.
