Published: March 2021

To describe an unusual case of retinoblastoma in adult Saudi. A 21-year-old Saudi male developed acute unilateral visual loss due to a large intraocular lesion in his left eye. Within five days of presentation, the tumor enlarged rapidly causing angle closure glaucoma and orbital cellulitis like picture. The patient underwent enucleation and the histopathology specimen confirmed the presence of an undifferentiated type tumor cell that was consistent with retinoblastoma with choroidal and optic nerve invasion. Retinoblastoma should be considered in the differential diagnosis of an intraocular mass in adults. To the best of our knowledge, this is the first reported case of an adult presentation of retinoblastoma in Saudi patient.
Clinical Challenges in Managing Zolpidem Use Disorder
Authors: Kini Ganesh K. , Raju Mohan S.
Published: March 2021

Zolpidem was popularized as a hypnotic with low abuse potential in the early years of its introduction. However, several cases of zolpidem use disorder necessitating medical intervention have been reported from across the world. The absence of their mention in standard treatment guidelines presents clinicians with significant challenges in managing craving and withdrawal symptoms in patients. We report a case of a 26-year-old male who presented to us with zolpidem misuse to cope with depression for two long years. We would like to draw attention to the clinical challenges we faced in managing the case. We urge apex health bodies to consider developing evidence-based recommendations or standards of treatment of zolpidem use disorder.

Published: March 2021

There are many unknown genetic factors that lead to infertility in nonobstructive azoospermia men. Here, we performed whole-exome sequencing in blood samples obtained from 40 azoospermia patients with meiotic arrest and found a novel c.151_154del (p.D51fs) frame-shift mutation in exon 3 of the testis expressed 11 (TEX11) gene in one patient. Sanger sequencing analysis of the patient and 288 fertile men was performed to validate the mutation. Immunohistochemical analysis showed TEX11 expression in late-pachytene spermatocytes and in round spermatids in fertile human testes. In contrast, testes of the patient with TEX11 mutation underwent meiotic arrest and lacked TEX11 expression. Western blotting of human embryonic kidney (HEK293) cells transfected with a vector for the p.D51fs TEX11 variant detected no TEX11 expression. In conclusion, we identified a novel frame-shift mutation in the TEX11 gene in an azoospermia patient, emphasizing that this gene should be included in genetic screening panels for the clinical evaluation of azoospermia patients.

Published: March 2021

Turmeric exhibits a big promise as a therapeutic agent in the management of oral submucous fibrosis (OSMF). The primary aim of our study is to synthesize the evidence of the use of turmeric/curcumin in the management of OSMF. The secondary goal of this study is to assess the limitations of previous studies to identify gaps in evidence for future research and give an evidence-based recommendation regarding the usage of turmeric/curcumin for OSMF patients and outline the direction of research. A comprehensive search of PubMed, Web of Science, Scopus, Cochrane Library database, Google Scholar, clinical trial registries, and hand searching was conducted from inception until December 2018. This systematic review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (guidelines). In this review, 11 articles were selected for qualitative analysis and 3 out of 11 were selected for meta-analysis. Of these 11 studies, involving 428 patients, 7 were randomized control trials (RCTs), 1 was a nonrandomized trial, and 3 were observational studies. Turmeric was found to be effective in reducing signs and symptoms of OSMF in all 11 studies. All the studies included in this review have reported improvement in mouth opening after treatment with turmeric formulations. This could also be concluded from the meta-analysis of three RCTs. Similar improvement in tongue protrusion, burning sensation, and cheek flexibility has been reported. The lack of reliable evidence for the effectiveness of turmeric for the management of OSMF is illustrated by the paucity and poor methodological quality of studies retrieved for this review. We recommend that RCTs are needed using larger sample size with longer duration follow-up with special attention to the recurrence of signs and symptoms.

Published: March 2021

Coronavirus infection (COVID-19) has significantly increased the mortality and morbidity rates worldwide. The present study was conducted to assess the general public’s awareness of COVID-19 and its association with mental health, dietary habits, and physical activity. A web-based survey was conducted to gather information about demographics, knowledge about COVID-19, dietary habits, mental health, and anthropometry among the general public of Pakistan. Descriptive statistics, chi-square test, and multiple logistic regression were used for data analysis. The majority of the participants were suffering from anxiety (71.0%) and depression (52.0%) during the COVID-19 pandemic; 32.4% of participants had poor COVID-19–related knowledge. COVID-19 lockdown reduced the physical activity of 66.9% of participants and increased weight of 38.8% of the survey participants. Demographic variables, including age, gender, ethnicity, education, employment, family type, and geographical location, were significantly associated with knowledge about COVID-19 (P < 0.05). Depression was inversely associated with COVID-19 knowledge (P < 0.05). Healthy changes in dietary habits including decreased consumption of fast foods, soft and cola drinks, fruit drinks, cooked meat (outside the home), sugar, and fats, and were associated with increased knowledge of COVID-19. Vitamin C and immunity-boosting supplement consumption were significantly associated with increased knowledge regarding COVID-19 (< 0.05). Inadequate knowledge about COVID-19 and the presence of anxiety and depression were found among most of the study participants. There is a need to conduct educational seminars to limit the health consequences resulting from COVID-19 lockdown.

Authors: Halise Şeyma ÖZÇELEBİ  , Murat ERMAN
Published: March 2021

Güneydoğu Anadolu bölgesi yaz dönemindeki aşırı sıcak ve kuru iklim özellikleri nedeniyle fasulye yetiştiriciliğine uygun değildir. Fasulye tarımına bir alternatif olarak börülce bitkisinin bölge tarımsal üretim desenine bir alternatif olabileceği düşünülmektedir. Börülce, sıcak ve kurak iklim koşullarına toleransı daha yüksek olan bir cinstir. Türkiye’de üretilen toplam börülcenin %75’i Ege bölgesinde yetiştirilmekte ve bu üretimin %45’i ise İzmir ilinde gerçekleşmektedir. Bu çalışma, farklı börülce genotiplerinin Siirt koşullarına adaptasyonunun belirlenmesi amacıyla yürütülmüştür. Materyal olarak 3 adet yerel popülasyon ve 3 adet tescilli çeşit (Karnıkara, Karagöz, Akkız) kullanılmıştır. Çalışmada, çıkış süresi, çiçeklenme süresi, bakla bağlama süresi, bitki boyu, bitkide dal sayısı, ilk bakla yüksekliği, bakla uzunluğu, bitkide bakla sayısı, baklada tane sayısı, bitkide tane sayısı, 1000-tane ağırlığı, biyolojik verim, tane verimi ve hasat indeksi incelenmiştir. Çalışma sonucunda çıkış süresi ve bitkide dal sayısı hariç incelenen diğer özellikler bakımından çeşit ve yerel popülasyonlar arasında oluşan farklılıkların istatistiki açıdan önemli olduğu tespit edilmiştir. Çalışmada kullanılan genotiplere ait tane verimi değerleri 76.6-223.7 kg/da arasında değişkenlik göstermiş ve en yüksek tane verimi Karagöz çeşidinden elde edilmiştir. Sonuç olarak, Karagöz çeşidinin Siirt ekolojik koşullarında yetiştiricilik açısından önemli bir potansiyele sahip olduğu belirlenmiştir.

Published: March 2021

Introduction: Peripartum cardiomyopathy is a rare disease that is difficult to diagnose and treat. Clinical findings are similar with heart failure. New treatments are needed in addition to the treatment of heart failure.

Case Report: A 32-year-old woman presented with symptoms of heart failure 4 days after first delivery. Chest X-ray showed cardiomegaly. Serum BNP level was high. Transthoracic echocardiography (TTE) indicated dilated left atrium and left ventricle, severe mitral regurgitation and ventricular dysfunction. The global longitudinal strain was – 9.1%. Cardiac magnetic resonance imaging (MRI) revealed mid-myocardial staining detected in late phase images. Concomitant bromocriptine (2,5 mg po twice a day for 15 days and then 2,5 mg po once a day for 15 days) was used with standard heart failure therapy. At 6 months, TTE and cardiac MRI revealed normal biventricular function and size. Global longitudinal strain was –14%.

Conclusion: Patients with peripartum cardiomyopathy may benefit from bromocriptine.

Abstract

Autoimmune hemolytic anemia (AIHA) is a rare disease with a rate of 1-3 in 100,000 in adults. AIHA are defined as primary (idiopathic) or secondary depending on the presence or absence of accompanying disease. Secondary causes include drugs, immunodeficiencies, infections, other autoimmune diseases, or malignancies. Here, we report an 42-year-old female presented to us with diarrhea, nausea-vomiting, fever, chills and jaundice for two days. Hematological investigations revealed hemolytic anemia. Direct Coombs test was positive. The patient was diagnosed acute tubuler necrosis with autoimmune hemolytic anemia. Methylprednisolone 40 mg/day was started considering autoimmune hemolytic anemia. She was on hemodialysis at regular intervals. After 4 weeks, the patient was symptomatically improved with remission of acute tubuler necrosis and hemolytic anemia. In our case, the association of AIHA due to acute gastroenteritis and acute tubular insufficiency was considered suitable for the presentation because of its rare occurrence.

A conjuntura, no entanto, incide negativamente sobre a classe trabalhadora, que é impactada pelas ações do governo federal em suas tentativas de salvaguardar a dinâmica capitalista em meio as incertezas e instabilidades que pairam sobre o mundo do trabalho. O presente artigo tem por objetivo realizar uma análise dessa combinação, que é a crise do governo Bolsonaro e o quadro pandêmico. Buscar-se-á fornecer elementos para uma interpretação crítica da realidade nacional atual, haja vista uma perspectiva histórico-crítica da trajetória brasileira sob a hegemonia neoliberal.
Lesional Diagnostic Approach of Common Dermatoses in Children at the University Clinics of Kinshasa - Democratic Republic of Congo
Authors: Joelle Seudjip Nono Lydie
Published: March 2021

Context and objectives: Several authors approach epidemiological studies on dermatoses using an etiological diagnostic approach; the Willaniste school being mostly reserved for learners of dermatology and/or non-dermatologist doctors. The objective of this study is to determine the profile of dermatoses in children using exclusively the type of elementary lesion. Methods: In a retrospective, analytical and descriptive study, the data of children with dermatoses followed in the Dermatology Service of the University Clinics of Kinshasa between June 1, 2009 and December 31, were collected. The parameters of interest included epidemiological and clinical characteristics.

Results: The hospital frequency of dermatoses in children (DC) according to the lesional diagnostic approach is 40.89% (818/1994). Their median age was 60 months (QEI 60-65.9) with a female predominance (55.7%, sex ratio of 1.25/1). There were more infants (30.6%). DC predominated in the dry season (54%). The entangled (21.02%) and vesicular (20.29%) lesional types were the most numerous, with ringworm of the scalp (31.9%) and atopic dermatitis (54.2%) respectively. The papular, erythematous, tumor and entangled lesion types were related to sex and age; pustular and tumor exclusively related to the season, in a statistically significant way (p ˂ 0.05). Taken as a whole, the most frequent dermatoses were atopic dermatitis (11%), prurigo strophulus (10.8%), impetigo (7.4%), Tinea capitis (6.7%) and scabiosis (6.4%).

Conclusion: The importance of this work lies in the interest of taking into account the two approaches, lesional and etiological of dermatoses, for their global management and research studies. Indeed, the lesional approach, also important in the study of dermatoses, appears to our knowledge to be poor in references in the literature.

An Autoethnography: Constructing (& Interpreting) Cross - Cultural Awareness through the Mind of a Peace Corps Volunteer
Authors: Carano Kenneth
Published: March 2021

In the form of an autoethnography, a returned Peace Corps volunteer examines how, when, and if, he was able to establish a significant level of cross - cultural awareness while living in Surname, South America for two years. Employing a process called emotional recall, the author analyzed two years worth of personal journals kept during his time in Suriname. The author writes about the explored interactions of his physical/temporal reality and “enacted” reality to provide examples of going through the first three levels and his fleeting attainment of the fourth level of cross - cultural awareness. Ultimately, one of the primary interpretations the author concludes from this examination is that power structures and personal perceptions have a great influence on cultural experiences and how those experiences are perceived to apply meaning.

Los retos que enmarca la cuarta revolución industrial (4Ri) para los emprendedores emergentes, exige que los procesos formativos en las Instituciones de Educación Superior (IES) proyecten su impacto de manera más efectiva en cuanto a las competencias a desarrollar a través de los diferentes cursos encaminados a la formación para el emprendimiento. Es evidente, para la transformación social de los territorios, que se lleven a cabo emprendimientos con sentido social que promuevan y movilicen el desarrollo de las comunidades. Para llevar a cabo un ejercicio coherente entre la formación y el impacto social, es imperante que las IES, que se encargan de la formación a nivel profesional, realicen un trabajo interno en el que se proponga, a nivel curricular y de forma transversal, el desarrollo de una estrategia que se materialice a través de diferentes ciclos de formación promoviendo la innovación social como parte de la identidad institucional en el ejercicio del emprendimiento de sus estudiantes y graduados, atendiendo a las necesidades sociales que implica los emprendimientos emergentes en el contexto de la 4Ri. Este estudio cualitativo, interpretativo, tiene como objetivo presentar la incorporación del componente de innovación social al Proyecto Educativo de una IES, a partir de acciones de “intrainnovación social”.
La deserción escolar, un abordaje desde el enfoque de la Ecología del Desarrollo Humano de Bronfenbrenner
Authors:   Secretaría de Educación Pública, Hernández Moreno Héctor Azael , Osorio Calderón Jesús ,   Universidad Autónoma de Nuevo León, Gálvez Santillán Elizabeth ,   Universidad Autónoma de Nuevo León
Published: March 2021

El presente documento es un esfuerzo de reflexión teórica para analizar el problema de la deserción escolar desde el enfoque de la Ecología del Desarrollo Humano de Urie Bronfenbrenner. El trabajo que se realizó es producto de una revisión documental sobre las posturas de diversos autores con relación a los diferentes factores que propician este fenómeno en el sistema educativo. Dentro de los hallazgos vislumbra que los elementos que repercuten en la deserción escolar del estudiante provienen de los diversos ambientes del modelo ecológico los cuales permiten que el sistema educativo tenga el control y poder para dominar la educación que un estudiante puede lograr. Dado que estos diferentes elementos o factores se encuentran distribuidos en las distintas dimensiones o ambientes del modelo provoca que los filtros sociales sean “imperceptibles” para los estudiantes y la sociedad en su conjunto, llevándolos a pensar que si no lograron terminar sus estudios fue porque lo merecían y no se percaten de que el sistema educativo se encuentra estructurado para que no todos logren concluir sus estudios. Es importante considerar que controlar cuantos pueden graduarse debe acompañarse con medidas para ampliar las oportunidades que puedan tener los desertores para integrarse a la sociedad de la mejor manera y no caigan en actividades que los denigre o que eleven la inseguridad en la sociedad.

Authors:   Universidad del Sinú Seccional Cartagena, Tirado Amador Lesbia Rosa
Published: March 2021

La autoeficacia general, es la sensación de competencia total para afrontar nuevas tareas y situaciones dificiles. La expectativa de autoeficacia influye en sentimientos, pensamientos y acciones. Al existir una buena percepción se aceptan las propias habilidades y las personas que se sienten eficaces, eligen tareas desafiantes, y adquieren persistencia en sus propósitos. Esta es la situaciòn deseable en quienes estudian disciplinas desafiantes y estresantes como la odontología. El objetivo del presente estudio fue determinar la percepción de autoeficacia general en estudiantes de odontología en práctica clínica de una Universidad privada en Cartagena. Se realizó un estudio descriptivo de corte transversal en 2017, a partir de 79 estudiantes, de semestres clínicos. Para recolectar la información se diseñó un cuestionario para variables demográficas y se incluyó el Test de Autoeficacia General. Para el análisis se realizó matriz de datos en Excel para Windows 10® y stagraphic centurión, inicialmente se midió la fiabilidad de la escala mediante el alfa de cronbach, luego se empleó estadística descriptiva. Para obtener un descriptivo global de autoeficacia se aplicó el cálculo de la media aritmética. Los principales hallazgos fueron la edad promedio de los participantes fue de 22,68 años (DE= 2,49). De la población estudiada 59,76% correspondió al sexo femenino y más del 80% solo se dedican a estudiar y son solteros. En lo que respecta a la autoeficacia, se pudo identificar que el puntaje promedio global fue 33,1, que evidencia una percepción de autoeficacia alta en los estudiantes participantes. En conclusión, poco más de la mitad de la población estudiada se considera auto eficaz para afrontar cualquier tipo de circunstancia, no obstante, hay un porcentaje que no siente la capacidad de ejecutar acciones para llegar al éxito, por lo que se debe buscar modificar las proyecciones de los estudiantes por medio acciones desde bienestar Universitario.
Cultura, identidad e innovación ante la sostenibilidad artesanal
Authors:   Corporación Universitaria Antonio José de Sucre, Lugo Hernández Emily , Huertas Netty Consuelo ,   Universidad Tecnológica de Bolívar, Muñoz Cardona Yuneris ,   Universidad Tecnológica de Bolívar
Published: March 2021

La región Caribe colombiana es reconocida por su diversidad cultural y la presencia de grupos indígenas, cuyas costumbres y actividades económicas generan gran valor patrimonial al territorio; pero que a su vez son caracterizadas por sus niveles de pobreza; hecho que motivó al proyecto a la búsqueda de una propuesta para el desarrollo sostenible de las asociaciones de artesanos de la Región Caribe; considerándolos como representantes de estas culturas y en peligro de extinción. El proyecto se fundamentó en una metodología participativa con representantes de las asociaciones de cada departamento; quienes a través de grupos focales y talleres evaluaron su posición frente a los retos del mercado global y la sostenibilidad no solo de sus actividades económicas, sino de sus comunidades e identidad. Dentro del análisis los artesanos manifestaron que la sostenibilidad de sus comunidades está en riesgo por la poca valorización de sus tradiciones; la entrada de mercancías industrializadas que replican sus bordados, texturas y son comercializadas por valores económicos inferiores; en relación a la penetración de otras culturas manifestaron verlas como oportunidad para la dinamización de sus productos y reconocimiento de estos. Finalmente, se concluyó que para la sostenibilidad se hace necesario la formación y fortalecimiento de las asociaciones en la cadena de exportación, comercialización de sus artesanías; así como la institucionalización de cursos que promuevan el rescate del valor cultural y de identidad de estas culturas. De igual forma, es pertinente la intervención e inversión del estado en la generación de materia prima al alcance de la comunidad y el saneamiento de necesidades básicas.
Cognitive Biases and the Cultural Disconnect between Engineers and Decision-makers
Authors: Booker Nigel , Gates Jeffrey D. , Knights Peter
Published: March 2021

Engineering culture is alien to the way the average person thinks and makes decisions. There is a dichotomy between the evidence-based analytical methodologies used by engineers and the intuitive or heuristic processes commonly used by the general public. Both can be appropriate in context, but wrong choices can lead to undesirable and sometimes dire consequences. For the recommendations from an engineering analysis to be accepted by non-technical decision-makers, the findings must be presented in a manner that takes account of human factors. Successful engineers are those who are proficient in translating the language of their technical discipline into that of broader society. A key skill is consequential reasoning, which is contained within engineering codes of ethics but is also critical to the persuasive power of analytical findings. Students and early-career engineers need structured learning in communication and in socio-cultural and emotional intelligence. They need exposure to cognitive psychology and epistemology, especially in relation to bias and false logic. If formal humanities courses cannot be accommodated in the undergraduate engineering degree, then post-graduate and continuing professional development opportunities should be offered.

Concepções de professores de matemática em portugal – um olhar a partir do ensino por competências
Authors: Vaz Leonardo José Leite da Rocha , Santos Maria Leonor de Almeida Domingues
Published: March 2021

O presente texto tem por objetivo analisar as concepções pedagógicas de professoras de Matemática do Ensino Básico e Secundário de Portugal, à luz do modelo de Ensino por Competências. Discutimos os modelos de Ensino por Conteúdos e por Competências, não se limitando aos conceitos propriamente ditos, mas também suas bases epistemológicas e implicações para o trabalho docente. Para contextuar nossa análise, efetuamos uma breve comparação entre os programas portugueses de Matemática de 2007 e 2013. Finalmente, analisamos as falas das docentes entrevistadas, no que respeita ao papel do ensino e seus conteúdos, gestão curricular, avaliação e interação com os estudantes. Concluímos que há professoras cujas concepções a respeito de suas práticas pedagógicas constituem um modelo coerente com suas concepções epistemológicas. Mas há também docentes que, apesar de manifestarem concepções construtivistas a respeito do ensino de Matemática, mantêm práticas pedagógicas características do modelo behaviorista. A pressão da preparação para as provas no estilo tradicional e a extensão dos programas são dois obstáculos que os professores enunciam para o desenvolvimento de práticas mais conducentes com as suas concepções, tal como se verifica no Brasil.
Para aonde vai esse táxi? Uma revisão da literatura sobre a Geometria do Táxi no Brasil
Authors: Silva Elizabeth Cristina Rosendo Tomé da , Bellemain Paula Moreira Baltar , Galvão Thyana Farias
Published: March 2021

A Geometria do Táxi vem sendo inserida aos poucos nas discussões sobre as geometrias não euclidianas na educação brasileira, acarretando assim o surgimento de diversas pesquisas sobre esta temática. Neste trabalho, que corresponde a um recorte de uma dissertação de mestrado, apresentamos um breve panorama das produções feitas no Brasil, entre os anos de 2010 e 2019, acerca da Geometria do Táxi no ensino da matemática. A metodologia empregada neste estudo contempla elementos de uma pesquisa bibliográfica, a partir da qual foram investigados artigos científicos, teses e dissertações em duas bases de dados online. Os textos encontrados foram, inicialmente, filtrados de acordo com os objetivos da pesquisa, resultando num corpus de 25 produções. Os trabalhos foram organizados com base em três categorias: natureza das pesquisas, público alvo e tipos de recursos utilizados. Concluímos que a maioria das pesquisas trazem resultados de aplicações da Geometria do Táxi predominantemente com sujeitos da educação básica, demonstrando o potencial desta geometria para a compreensão e desenvolvimento do pensamento matemático e geométrico ainda na formação básica. Destacamos também o uso de diferentes recursos, como softwares, papel milimetrado e jogos, para trabalhar estes conceitos, a partir de abordagens e focos distintos.
Démonstration par l’absurde: une épine dans l´enseignement et l´apprentissage des mathématiques - une étude de cas au Mali
Authors: Bamba Aboubacar , Almouloud Saddo Ag
Published: March 2021

Le présent travail a comme thème « Une épine dans l’enseignement et l’apprentissage des mathématiques : Une étude de cas au Mali . Pour le réaliser nous avons fait une revue de la littérature ayant porté sur des travaux autour du raisonnement par l'absurde et l’étude institutionnelle de la démonstration par l’absurde. La problématique est relative au rôle que la démonstration par l’absurde joue dans les pratiques de classe et dans les manuels scolaires et son absence dans les programmes. Les questions de recherche sont libellées comme suit : Au Mali la démonstration par l’absurde est-elle considérée comme étant au-dessus des capacités de l’élève du secondaire ? Au regard d’un énoncé, le futur enseignant reconnait-il la nécessité d’une démonstration par l’absurde ou alors peut-il le transformer de manière qu’une démonstration par l’absurde s’impose ? L’étude mathématique de la démonstration par l’absurde, nous a permis d’analyser cette méthode de démonstration comme savoir de référence et de faire son interprétation logique. La classification des problèmes faite par le premier auteur dans sa thèse, nous a permis de faire le choix des variables didactiques. La partie expérimentale comporte le choix et l’analyse a priori de trois problèmes proposés à des élèves-professeurs de l’École Normale Supérieure de Bamako, la passation des items en une séance, l’analyse à postériori des productions. Les élèves-professeurs ont été mis dans une situation de résolution de problèmes par la méthode de démonstration par l’absurde pour éventuellement connaitre leur rapport à la démonstration par l’absurde. L’analyse a postériori nous a permis de constater la confirmation du fait que la démonstration par l’absurde pose des difficultés aux professeurs de l’enseignement secondaire.

Panama’s statistical system is well established by a legal framework that generally provides the necessary authority for the collection and compilation of statistics. Panama has a well-developed macroeconomic statistical system and the government recognizes the importance of good statistics for policy and investment decisions. This Report on the Observance of Standards and Codes (ROSC) is a follow-up to the Panama ROSC issued in 2006. Since 2006, Panama has acted upon a number of the recommendations of the previous ROSC, has passed and implemented new statistical legislation, created the National Statistical Institute and enhanced its statistical compilation and dissemination practices. This report assesses the current state of the statistical system and makes a number of recommendations related to future developments that will further enhance the statistical system. The legal framework assigns responsibility for the socio-economic statistics to the Comptroller General of the Republic of Panama (CG), which is subsequently delegated to the National Statistical Institute (INEC). Among other social and economic data INEC compiles and disseminates national accounts, consumer price index (CPI), government finance, and external statistics. The MEF in collaboration with INEC also compiles and disseminates fiscal statistics. Given Panama’s long history of dollarization and absence of a central bank, there is no assignment of responsibility for compiling and disseminating a complete set of monetary and financial statistics. Instead, the Superintendency of Banks of Panama (SBP) produces banking sector statistics in line with its functions. Consequently, statistical practices for some elements of the DQAF do not apply to this sector (Box 1). Opportunities exist for improving the methodological basis and source data for most datasets.

The current internet architecture cannot manage the massive data volumes produced by the smart IoT-based healthcare systems. Very recently, the idea of Software-Defined Networking (SDN) has surfaced to resolve the issues related to networking. The incorporation of SDN technology in IoT-based healthcare systems can possibly solve the existing quality of service and data management issues. Furthermore, the IoT-based healthcare system can attain enhanced Quality of Service (QoS) through the employment of such schemes that use shortest-path routing algorithms and offer higher bandwidth to lesser delay paths as per the QoS requirements. In this study, the SDN technology is integrated with IoT-based healthcare systems, and the delay is reduced for delay-sensitive applications by using the Bellman-Ford algorithm. The proposed scheme is deployed using the POX controller and can effectively handle the existing QoS issues in the IoT healthcare systems. The simulation results of the proposed scheme show a clear drop in delay values in comparison to the benchmark scheme.
