Alteración del colágeno en la Hipertrofia Gingival en pacientes con ortodoncia: caracterización histológica e inmunohistoquímica
Authors: Simancas Escorcia Victor Hugo , Lozada Martínez Ariana , Díaz Caballero Antonio
Published: October 2021

Introducción: la hipertrofia gingival (HG) es el aumento del volumen de la encía asociado a ciertas enfermedades sistémicas, hereditarias (idiopático), ingesta de algunos medicamentos o a factores locales como el tratamiento ortodóntico, capaz de provocar cambios histológicos en el tejido conectivo gingival. Objetivo: describir las características histológicas e identificar el colágeno tipo I y tipo III en tejidos gingivales de sujetos con hipertrofia gingival portadores de ortodoncia. Materiales y métodos: Se diseñó un estudio de casos y controles que incluyó el análisis de biopsias de tejido gingival de 12 pacientes sometidos a cirugías periodontales. La muestra se dividió en dos grupos: individuos sanos (control; n= 6) y pacientes con HG portadores de ortodoncia (pacientes; n= 6). Las muestras fueron procesadas e incluidas en parafina. Las tinciones Masson-Goldner y rojo sirius/verde rápido fueron empleadas. El colágeno tipo I y tipo III fueron identificados mediante inmunohistoquímica con anticuerpos monoclonales. Resultados: en los pacientes con HG portadores de ortodoncia se observó un epitelio hiperplásico y tejido conectivo denso con abundantes fibras de colágeno distribuidos aleatoriamente. La inmunodetención de colágeno tipo I indicó la presencia de abundantes fibras desorganizadas y el colágeno tipo III fue inmunolocalizado subyacente a la membrana basal, vasos sanguíneos y toda la extensión del tejido conectivo de los pacientes con HG con tratamiento ortodóntico. Conclusión: la acumulación de fibras de colágeno, particularmente del colágeno tipo I y tipo III, son hallazgos histológicos que caracterizan la HG en pacientes portadores de ortodoncia. Futuros estudios son necesarios para dilucidar el fenotipo de los fibroblastos gingivales y la probable pérdida homeostática entre la producción y degradación de colágeno en esta patología.
El ir y venir de las revistas científicas de ciencias de la salud en Colombia
Authors: Pérez Anaya Oskarly , Wilches Visbal Jorge Homero , Castillo Pedraza Midian Clara
Published: October 2021

Las revistas científicas son reconocidas como el medio de difusión más consolidado de la investigación formal. En gran parte, esto obedece al proceso de revisión exhaustiva de pares y a una minuciosa tarea de selección editorial1. En 1996, el Departamento Administrativo de Ciencia, Tecnología e Innovación – Colciencias (hoy Ministerio deCiencia, Tecnología e Innovación - Minciencias), inició la evaluación oficial de las revistas científicas colombianas, a través de una convocatoria que objetivaba mejorar y formalizar los estándares editoriales de las revistas. Sin embargo, apenas 26 participaron de la convocatoria. Pocos años después, con la expedición del Decreto 1279 de 2002, que regula los salarios y prestaciones de los docentes de las universidades públicas, se le asignó latarea a Colciencias de elaborar y mantener el Sistema Nacional de Indexación y Homologación de Publicaciones Especializadas de Ciencia, Tecnología e Innovación (Publindex). Desde entonces, Publindex se ha encargado de reconocer e indexar a las revistas colombianas en cuatro categorías: A1, A2, B y C2.
¿Los médicos/as deberíamos ser llamados como doctores antes que por nuestro nombre? Es tiempo de cambiar
Authors: García Perdomo Herney Andres
Published: October 2021

Desde tiempos ancestrales al médico se le ha llamado: “médico tal” o “doctor tal”. Incluso, los mismos médicos se presentan entre colegas como: soy el doctor... y mencionan el apellido. Dejando de lado sus nombres de pila. ¿Por qué deben colocarse el doctor/a antes que su propio nombre? ¿Es por respeto; por jerarquía; por demostrar lo que han estudiado? Tal vez es una mezcla de todo, e incluso de otros elementos que tendremos que describir. De acuerdo con la real academia de la lengua, el término doctor o doctora es dado a la persona que tiene el más alto nivel académico: un doctorado (PhD). Además, se le dice al médico u otro profesional especializado en alguna técnica terapéutica como el podólogo o el dentista. En algunos escenarios, por ejemplo, en atención primaria, es más relevante e importante acercarse al paciente por el nombre propio, sin que existan intermediarios que limiten la relación. Además, entre profesionales puede ser importante eliminar esos títulos; lo fundamental en el cuidado de la salud sería, que independiente de los títulos o jerarquías, se puedan cumplir los objetivos y los lineamientos establecidos en el lugar de trabajo con liderazgo horizontal y responsabilidad.

Authors: Alvarado Jorge , Quintero Lesmes Doris Cristiana , Carmona Valle Juan Carlos , Franco Lopez Maritza , Niederbacher Velásquez Jürg
Published: October 2021

Introducción: la pandemia por SARS-CoV-2 generó el cierre de los colegios y el inicio de la educación virtual, como medida para disminuir la propagación del virus. Rápidamente, se planteó el regreso a los colegios; sin embargo, es probable que exista un rechazo de los padres por el regreso a clases de forma presencial o mediante alternancia. Por esta razón, se evaluaron los factores asociados a esta oposición. Materiales y métodos: se realizó un estudio analítico de corte transversal mediante una encuesta, dirigida a padres que acuden a consultorios con sus hijos en varias ciudades de Colombia. Se determinó el porcentaje de padres que deseaban mantener la escolarización mediante la virtualidad y los factores asociados que motivan a no aceptar el pronto retorno a clases presenciales. Se realizó un análisis de regresión binomial para estimar razones de prevalencia (RP), ajustado a la edad de los padres, tomando como variable dependiente la aceptación de la virtualidad como estrategia para no regresar a los colegios, y se determinaron los factores de mayor importancia en la no aceptación del retorno a clases. Resultados: el 81,06 % de los padres no acepta el retorno a clase de forma presencial. El principal factor asociados a esta decisión fue que alguno de los padres presentara alguna comorbilidad, principalmente, hipertensión y obesidad. Tener hijos mayores de 10 años (RP: 2,64: IC 95 %: 1,48-4,72), convivir con personas mayores de 70 años (RP: 2,2; IC 95 %; 1,46-3,29) y conocer alguna persona fallecida por COVID-19 (RP: 1,86; IC 95 %: 1,42-2,44) también fueron asociadas a no aceptar el retorno a clase presencial. Conclusiones: existe una clara tendencia a mantener la virtualidad como opción educativa en Colombia para el no regreso a clases presenciales en población de estrato medio y alto. Los factores asociados sugieren una forma de protección familiar. Esta evidencia debe considerarse específica para el periodo de recolección de datos y el grupo incluido en el estudio. Se requieren estudios en los estratos socioeconómicos más bajos, donde se supone ocurren más efectos adversos asociados al no retorno a clases presenciales.

Introducción: la polifarmacia y la prescripción inapropiada (PI) se han visto relacionadas con múltiples variables, incluidas las de aspecto socioeconómico, sin embargo, la evidencia en esta asociación es escasa y heterogénea. Objetivo: evaluar la asociación entre la polifarmacia y la prescripción inapropiada de medicamentos en adultos mayores de 60 años según su clase social. Materiales y métodos: Estudio piloto de diseño descriptivo, corte transversal realizada en la ciudad de Bucaramanga-Colombia, con una muestra de 135 adultos mayores de 60 años. Se realizó una encuesta donde se registraron datos sociodemográficos, estado de salud en el último mes, comorbilidades, medicamentos de uso crónico y escalas de funcionalidad. Resultados: no se encontró asociación estadísticamente significativa entre prescripción inapropiada y polifarmacia con la clase social y el nivel educativo (P=0,639). Sin embargo, el tener una filiación al sistema de seguridad social de tipo subsidiado estuvo significativamente asociada a la infra prescripción (P<0,029). La presencia de ingresos mensuales estuvo asociada con la presencia de polifarmacia (P<0,029) y prescripción inadecuada (P<0,033). Conclusiones: Existe una asociación entre algunas variables socioeconómicas, el número de médicos tratantes y algunas especialidades médicas con presentar polifarmacia y prescripción inapropiada de medicamentos.

Authors: Pretnar Ajda , Hočevar Tomaž , Curk Tomaž
Published: October 2021

Podatki o prometu nam lahko pomagajo odgovoriti na več vprašanj o mobilnosti ljudi. Opaženi vzorci razkrivajo, kako narod vozi, kaj počne med tednom in med konci tedna ter kako se navade ljudi spreminjajo čez leto. Tovrstne informacije nam pomagajo razumeti sedanje in prihodnje vedenje turistov ter omogočajo prilagoditev in vpliv na promet. Analizirali smo javno dostopen nabor podatkov števcev cestnega prometa v Sloveniji. Razvili smo računske metode za iskanje zanimivih vzorcev v prometu. Lokacije števcev prometa smo gručili glede na podobnosti v opazovanih prometnih profilih. Takšna avtomatizirana kvantitativna analiza velike količine podatkov je dragoceno orodje za odkrivanje zanimivih lastnosti v prometu. Odprti podatki števcev prometa v realnem času nudijo še globlji vpogled v mobilnost. Na podlagi opaženih korelacij med bližnjimi števci prometa smo ustvarili model cestnega omrežja. Z modelom smo analizirali prometni tok po cestnem om-režju in razvili metodo za štetje prometa v določeno izbrano regijo in iz nje.
Text Mining Tourism Literature
Authors: Pretnar Ajda , Curk Tomaž
Published: October 2021

Literature reviews are essential for understanding a specific domain as they map the main topics of current re-search. Our aim was to provide a framework for retrieving articles from online databases and analyzing them in a single script. We provide the analytical pipeline as open-source (https://github.com/tourism4-0/BibMine). The main research focus was on analyzing 318 abstracts from scientific papers on tourism and innovation, which we report in Zach et al. (2019). We used LDA topic modeling to uncover ten main topics, which we analyzed using pyLDAvis visualization. We used saliency and relevance scores to determine the main words that de-scribe a topic. The uncovered topics range from climate change and land use to smart destinations, travel expe-riences, and ICT. We performed similar analyses for the term "stakeholders," where we also observed the main verbs related to the query. Since verbs best define an activity, we used them to determine how stakeholders are involved in tourism development. Finally, we analyzed papers with the keyword "technology," where energy efficiency, VR, web technology, and augmented tourist experiences were the main topics.
Finding Errors in Programs for Processing Graphic Images using the Fuzzing Method
Authors: Baydin G.S. , Khizova M.V.
Published: October 2021

Increasing number of software for automated graphics processing requires effective testing methods. One of these methods is fuzzing, for which it is necessary to determine the most effective algorithms for creating test data in order to increase the number of errors found and minimize hardware resources. The comparison of algorithms for creating test data for finding errors in the executable code of programs designed for processing graphic images is the result of the performed research. Using Bayesian networks to describe fuzzing allows determining the relationships between structural components during testing. Based on the results of the comparison of fuzzing algorithms for creating test data, the most effective algorithms for finding errors in the executable code of programs for processing graphic images have been identified. The performance of the proposed algorithms was tested on a number of existing vulnerabilities classified as CVE (Common Vulnerabilities and Exposures). The processing of the results of experiments on the creation of test data was carried out using the simulation environment, allowing analyzing the testing process step by step. The obtained research results, algorithms for creating test data for finding errors can be used at various stages of software testing
Analysis of Supercritical Stability of Distributed Real-Time Information Systems
Authors: Vishnyakov I.E. , Ivanov I.P. , Odintsov O.A.
Published: October 2021

The article describes an approach to the numerical analysis of the stability of distributed information systems under a load that varies over time allowing for a short-term load exceeding critical values. Information systems are considered as imperfect queuing systems in which the intensity of the message flow may depend on the size of the queues of applications. Based on this approach, criteria for the stable and unstable behavior of the system under load are formulated, where the stable behavior of the system is understood as the ability of the system to return to its normal mode of operation independently when the external load drops below the critical value, and unstable one when there is the transition to an emergency state. As examples, the most common types of unstable systems are considered, as well as an example of a distributed system that implements a complex queuing system, which, depending on the characteristics of the service, can be either stable or unstable. The analysis of such a system is carried out, which is confirmed by the results of numerical simulation. Based on the analysis results, zones of stability and instability are determined. Features of the implementation of distributed real-time information systems are considered, practical recommendations for the implementation of sustainable information systems are given

Published: October 2021

Background: Tomato is an important vegetable crop of Himachal Pradesh grown during summer and rainy seasons. Although the produce of the tomato fetches lucrative rates in the plains of Northern India, yet, the production is threatened by plethora of factors viz., diseases, insect-pests and weeds which ultimately affects yield and quality of fruits. The planting methods, mulches and training systems played enormous role in maintaining the soil temperature and moisture. Methods: The present investigation was carried out to study the performance of tomato (var. Solan Lalima) crop under open field conditions with two different planting methods, three types of mulch treatments and two types of training systems. This experiment was conducted at Vegetable Research Farm of DR YSP, UHF, Nauni, Solan during the period from March to September, 2017-18 and similarly for the period from March to September, 2018-19. Result: The maximum soil temperature was recorded under blackmulch followed by silver/black polythene mulch and control during the standard meteorological week (March to September, 2017-18 and 2019). Soil moisture was found to be maximum those treatments where silver or black mulch was used as compared to black mulch plot under the open field conditions. The maximum fruit yield (140.71 kg/plot) was obtained under the raised bed planting system, black mulch and two stem training system and the corresponding value being 136.16 kg/plot for raised bed planting method, silver/black mulch and two stem training system.

Published: October 2021

Background: Vascular wilt caused by Fusarium oxysporum f.sp. lentis Vasu. and Srini. is a serious disease of lentil (Lens culinaris Medikus), causes severe yield losses worldwide. For effective disease resistance breeding the inheritance and mapping of wilt resistance gene (s) is necessary. Therefore, the present investigation was focused on study the mode of inheritance and tag/map gene (s) for fusarium wilt resistance in lentil. Methods: Bulked segregant analysis (BSA) approach was used to identify markers that were tightly linked to Fusarium wilt resistance gene. The inheritance and mapping of wilt-resistance gene (s) in lentil was investigated in F2 and F2:3 populations derived from L9-12×ILL10965 cross, whereas L9-12 and ILL10965 were susceptible and resistant parents, respectively. Result: More than two hundreds SSRs markers were surveyed for the parental polymorphism, of which twenty nine were found polymorphic. These polymorphic SSRs were used for the bulked-segregant analysis (BSA) using both parents and its respective resistant and susceptible bulks, and three SSRs viz. PBALC233, PBALC1409 and PBALC203 could distinguish the respective bulks. Linkage analysis showed two SSR markers, PBALC203 and PBALC1409 flanking the wilt resistance gene at 8.2 cM and 9.4 cM distance, respectively. Further, PBLAC233 was also found present on the same linkage group at a distance of 10.2 cM from PBLAC1409.

Published: October 2021

O presente artigo tem como objetivo analisar os motivos preponderantes da evasão de alunos de cinco cursos de formação técnica profissional de nível médio subsequente na modalidade Ensino a Distância - EaD, em uma Instituição de Ensino Federal. A pesquisa é do tipo exploratória, e foi utilizada uma abordagem quantitativa, sendo aplicado um questionário eletrônico, enviado por e-mails disponibilizados pela Instituição, no qual se buscou identificar o perfil dos alunos, assim como identificar os principais motivos que os levaram a evadir de seus cursos. Obteve-se, ao final da pesquisa, a resposta de 28 alunos, o que pode ser considerado um número baixo, contudo se conseguiu extrair respostas dos cinco cursos analisados. A dificuldade em se adquirir respostas para os questionários reflete em uma das maiores causas apontadas pelos alunos para a evasão: a presença de motivação. Além desta, falta de planejamento e de domínio no manuseio das ferramentas utilizadas pela plataforma Moodle. Os participantes afirmam sentir falta de uma maior relação interpessoal entre alunos, tutores e professores. Assim sendo, a partir dos resultados da pesquisa, conclui-se que os motivos de evasão dos alunos de ensino técnico subsequente na modalidade EaD são semelhantes aos de outros níveis e modalidades, conforme apontam os estudos apresentados neste trabalho.

Analysis of the opinions of academists in the field on the applicability of distance education in preschool education
Authors: Seven Serdal , Yurek Enes
Published: October 2021

The goal of this study is to examine the views of academicians working in the preschool teaching department on the applicability of the distance education model in preschool education. The study was carried out in a ‘phenomenological’ pattern, which is a qualitative research pattern. The research group comprised eight academicians working in preschool teaching departments of state/foundation universities in Istanbul during the 2020–2021 academic period. The study results indicate that participants expressed more limitations than positive aspects of applying the distance education model in preschool education. It is observed that participants agree that children will face some limitations in socio-emotional development fields, but might be supported in the cognitive development field when the distance education model is applied in preschool education. It is also understood that participants do not have a common view on language development, motor development and self-care skills. Inner-service training for inexperienced teachers on distance education to inform them about distance education practices in preschool education is suggested.

Research into ultrasoic and hydrodinamic cavitation phenomena in a hydraulic system
Authors: Stryczek Jaroslaw , Antoniak Piotr , Banas Michal , Stryczek Piotr , Yakhno Oleg , Luhovskyi Oleksandr , Kovaliov Vasilij
Published: October 2021

The article describes the course of the ultrasonic cavitation in a hydraulic tank and the hydrodynamic cavitation in a gear pump. The course of those phenomena was confirmed in experimental tests carried out with the use of a tank and a pump made of transparent plastics. It has been proved that the oscillator-cavitation system made according to the original project is useful to induce the phenomenon of ultrasonic cavitation. It has also been shown that the PIV visualization method, consisting in a special system of illuminating transparent objects and recording the flow through those objects with a fast camera, is useful for the studying of the cavitation phenomena.
A visible interaction between the ultrasonic and the hydrodynamic cavitation was observed. The induction of ultrasonic cavitation in the tank causes degassing of the oil, and the degassed oil supplying the pump reduces the hydrodynamic cavitation in its internal channels and clearances. This is an example of beneficial effects of the ultrasonic cavitation on the operation of a pump and a hydraulic system.
The presented work is an example of effective co-operation between the communities of Wroclaw University of Science and Technology and Igor Sikorsky Kiyv Politechnic Institute, National Technical University of Ukraine.

Sychev) and operational-procedural (methods for identifying the level of formation of mental operations (methods for identifying the ability to analyze, compare, generalize and classify) components of metacompetence. Comparative (chi-square test, Student's t-test) and correlation (Spearman's correlation coefficient ) analyzes. Results. A close relationship was revealed between the indicators of the potential readiness of future teachers for lifelong pedagogical education and individual components of metacompetence, characteristics of students' worldview, their intelligence and cognitive abilities. Conclusion. The results of the study suggest that the formation of future teachers' readiness for lifelong education should be based not only and not so much on stimulating their motivational activity, but also on creating conditions for the development of their worldview, intelligence, systemic, creative thinking and general cognitive abilities.
An Enteric Fistula to a Hip Fusion Mass, 30 Years After the Arthrodesis
Authors: Shafiei Seyyed Hossein , Nourbakhsh Amirsalar , Vasigh Mahtab
Published: October 2021

Case:

In this report, we describe a case of delayed enteric fistula to the hip fusion mass, 30 years after the hip fusion surgery with confusing symptoms at presentation.

Conclusion:

Fistula formation between bowel and the hip joint after a hip surgery is rare. Enteroarticular fistula can be fatal because of sepsis. The enteric fistula to the hip joint diagnosis may not always be straight forward, and it should be kept in mind as a probable differential diagnosis in many unrelated scenarios. Complete physical examination, preoperative sampling, paying attention to the intermittency of secretions during starvation, and timely consult with general surgeons can help.
Lymphatic Injury After Vertebral Column Resection from a Posterior Approach for Spinal Deformity Correction
Authors: Ladd Bryan , Jones Kristen , Polly David
Published: October 2021

Case:

We describe a case of lymphatic injury that occurred during a 2-level vertebral column resection for spinal deformity correction from a posterior-only approach. Large surgical drain volume output with laboratory findings of high levels of triglycerides and lymphocytes prompted conservative treatment with an elastic wrap bandage and a “no fat” diet. The patient responded to the treatment with no sequelae noted.

Conclusion:

Lymphatic complications are rare in spine surgery. All reported cases are associated with anterior approaches. The lymphatic injury presented here demonstrates the potential for this complication to occur during posterior-only approaches as well.
Calcaneal Reconstruction With Femoral Head Allograft Vascularized by an Osteocutaneous Medial Femoral Condyle Flap
Authors: Mehta Manish P. , Butler Bennet A. , Lanier Steven T. , Ko Jason H. , Kadakia Anish R.
Published: October 2021

Case:

A 25-year-old man presented with a closed calcaneal fracture after a 6-storey fall, complicated by osteomyelitis from fixation attempts necessitating near-complete debridement of his calcaneal tuberosity. He underwent a successful single-stage calcaneal and soft-tissue reconstruction using a femoral head structural allograft vascularized with an osteocutaneous medial femoral condyle flap. At the 18-month follow-up, his limb is largely pain-free and functional, allowing ambulation and his combined allograft-vascularized bone reconstruction shows radiographic evidence of incorporation.

Conclusion:

Calcaneal tuberosity reconstruction with a femoral head structural allograft and vascularized bone flap is a viable option for calcaneal tuberosity bone loss because of injury/infection.

Published: October 2021

Case:

We report a 4-year-old girl with congenital muscular torticollis (CMT) who was treated with sternocleidomastoid muscle (SCM) tenotomy using ultrasonography (US). Prior to the surgery, US was utilized to identify the clavicle and sternum branches of the SCM, sternohyoid muscles, internal jugular vein, and common carotid artery. Then, local anesthesia was injected into the layer between the fascial sheath of the SCM and carotid sheath to reduce bleeding and avoid vascular injury. During surgery, the SCM dissection was carefully conducted under US guidance to avoid vascular injury. No residual of SCM dissection and improvement of neck motion were confirmed before the skin closure. Postoperative course was good with no obvious complications in this patient.

Conclusion:

The intraoperative US investigation during SCM tenotomy is a useful procedure that provides vital information about dissection area of SCM and orientation of internal jugular vein that reduces the risk of insufficient tenotomy and vascular injury.
