Authors: Czowalla Lucas , Busch Dahlia , Fromberg Andrea , Gwiasda Peter , Wilde Mathias , Lanzendorf Martin
Published: November 2022

Die Verknüpfung des Fahrrades mit dem Öffentlichen Verkehr (ÖV) kann den Umweltverbund stärken, den Übergang von einem Verkehrssystem auf das andere erleichtern und eine attraktive Alternative zum motorisierten Individualverkehr schaffen. Die vorliegende Arbeit repräsentiert den ersten umfassenden Projektbericht innerhalb des Forschungsprojektes „Verbesserte Integration des Fahrrads in den öffentlichen Verkehr – Systematische Erschließung von Handlungsoptionen und Bewertung von Best-Practices“. Ziel dieser Publikation ist eine aktuelle Aufarbeitung des Standes der Forschung und der Praxis zu diesem Thema. Nach einer systematischen Darstellung wichtiger Forschungsstränge, werden zunächst Ergebnisse aus dem „Mobilität in Deutschland“-Datensatz hinsichtlich intermodaler Rad‐ÖV‐Nutzungsmuster präsentiert. Aufbauend darauf werden Datengrundlagen und generelle Erfordernisse an Erhebungsmethoden diskutiert, um die inter- und multimodale Verkehrsmittelnutzung tatsächlich beurteilen zu können. Die Darstellung des aktuellen Standes in der Praxis wird anhand von drei Schwerpunkt-Feldern vorgenommen: Bike and Ride Abstellanlagen an Haltestellen des ÖV, Radmitnahme in den Fahrzeugen des ÖV und Fahrradverleihsysteme. Dabei werden sowohl infrastrukturelle Maßnahmen als auch Betreiberkonzepte und Marketingaspekte behandelt. Ein weiteres Kapitel beschäftigt sich mit den Chancen und Herausforderungen im Zuge der fortschreitenden Digitalisierung und der Verbreitung von mobilen Endgeräten.
Zu Fuß unterwegs – Konflikte der Raumaufteilung für Fußgänger*innen im öffentlichen Straßenraum am Beispiel der Schweizer Straße in Frankfurt am Main
Authors: Selzer Sina
Published: November 2022

Die Straßen deutscher Städte werden überwiegend vom Automobil dominiert, was nicht nur die gebaute Umwelt prägt, sondern auch die politischen Entscheidungen beeinflusst, wenn es um die Verteilung des Straßenraumes geht. Dass jedoch am Anfang der Mobilität das Zufußgehen steht und ein gut geplanter städtischer Fußverkehr nicht nur einen Beitrag zur Sicherheit der Fußgänger*innen leistet, sondern auch die Zukunft urbaner Mobilität gewährleistet, wird oft vergessen. Obwohl der Fußverkehr zahlreiche Potentiale bietet, bekommt er im öffentlichen Raum deutlich weniger Entfaltungsspielraum zur Verfügung gestellt. Die Zufußgehenden werden dort häufig kanalisiert und an den Rand gedrängt, was Einfluss auf ihr Verhalten nimmt. Diese Marginalisierung der Fußgänger*innen wird zusätzlich hervorgerufen durch eine geringe Beachtung jener in der städtischen Planung und Politik sowie in der Wissenschaft und Gesellschaft. Demnach stehen sie im Konfliktverhältnis zur persistenten und sozial konstruierten Struktur der Straße. Die vorliegende Untersuchung überprüft, warum die Fortbewegung zu Fuß in der gebauten Straßenumwelt und ihrer Raumaufteilung im Vergleich zu anderen Verkehrsmitteln eine untergeordnete Rolle spielt und welchen Einfluss der planerische und politische Umgang und die Gestaltung des Straßenraumes darauf nimmt. Dies geschieht mittels eines Fallbeispiels in Frankfurt am Main, der Schweizer Straße. Im Rahmen der Studie werden Ergebnisse aus teilnehmenden Beobachtungen der Zufußgehenden der Schweizer Straße und deren Verhaltensweisen im öffentlichen Straßenraum sowie aus qualitativen Interviews mit Expert*innen der gebauten Straßenumwelt Frankfurts zusammengetragen. Das übergeordnete Ziel der Arbeit ist, ein Verständnis für die Wechselwirkung zwischen Raumstruktur, planerischem Einfluss und Mobilität zu entwickeln sowie die Konflikte der Raumaufteilung für die Fußgänger*innen herauszuarbeiten, um den Fußverkehr gezielter fördern zu können.

Authors: GÜLHAN Ayca , ÇOKLAR Hacer , AKBULUT Mehmet
Published: November 2022

In this study, purple basil leaves were dried in 3 different methods (oven, microwave, and shade drying) and then infused 5 different times in hot water at 90 oC. Analyses of total phenolic content, antioxidant activity, total monomeric anthocyanin content, and color parameters were performed on tea samples. When the analysis results were evaluated, the best results were determined in the tea samples prepared from the leaves dried in the oven and in the shade, at brewing times of 10 and 15 minutes. 45 minutes was the best infusion time for the tea sample prepared from microwave dried leaves. When the three different drying methods were compared, the shade drying method gave better results than the other drying methods. According to the highest values obtained from the analysis results, the effect of the functional compounds in the purple basil leaves on the tea was calculated. It was determined that the highest percentage of phenolic compounds in tea was found in the samples prepared by the shade drying method.

Published: November 2022

The most vital problems of humanity mentioned in SDGs are the consequences of climate change and biodiversity loss and problems with access to water and forest resources. Although there is a deep understanding of the problems, there are reasons that do not allow finding swift solutions, and the increasing funding gap for the relevant SDGs is one of them. This study aims to establish the connection between environmental protection investments and the achievement of environmentally oriented sustainable development goals across 31 European countries (26 EU Member States, 3 EFTA Countries, and Ukraine as a Candidate to EU). The paper employed the PLS-SEM approach. The obtained results proved that the accumulated amount of environmental protection investments does not have a statistically significant relationship with the integral indicators of SDG 6 “Clear water and sanitation,” SDG 13 “Climate action,” and SDG 15 “Life on land” (the coefficient of determination, the path coefficient, and the reliability coefficients were insignificant). The study of a similar relationship between the level and the directions of SDGs 6, 13, and 15 achievements also did not reveal any significant results. As the last step of the analysis, the hypothesis about a relationship between environmental protection investments and Environmental Performance Index components was also rejected. Therefore, the statistical significance and relevance of the analyzed indicators were not confirmed. Based on this, a conclusion was made about the insufficiency of investment resources for environmental protection to overcome the gap in achieving environmentally-oriented SDGs.

Published: November 2022

The qualitative case study aimed to investigate EFL learners’ perceptions of synchronous learning in EFL speaking classes. Although numerous studies have been on synchronous learning, only a few pieces of literature focused on learners’ perceptions in English as a foreign language (EFL) settings. The research was conducted in a speaking course at a private university in Indonesia. Seven undergraduate learners majoring in English education program participated in the research which employed semi-structured interviews to gain participants’ views on their attitudes and benefits during distance education. Thematic analysis was employed to analyze learners’ perspectives and answer the research questions. The research’s findings reveal that learners are satisfied with synchronous applications. Synchronous learning improves learners’ motivation and develops confidence in class. However, EFL learners experience language learning boredom while they are joining a synchronous mode of learning. The perceived benefits of synchronous learning cover free learning resources, flexibility, accessibility, and task completion. The findings highlight that synchronous language learning can be an alternative for teaching speaking skills. English teachers need to implement a well-planned and well-executed synchronous learning strategy in teaching EFL speaking.
Heredogramas e parentesco no Cariri Paraibano
Authors: Marques Heytor de Queiroz , Maciel Neves Ednalva
Published: November 2022

Problematizar como a presença das Mucopolissacaridoses e o heredograma mobilizam reflexões acerca do parentesco entre os casais, em que categorias de consanguinidade e ascendente comum estabelecem arranjos diferentes para o entendimento do adoecimento. A etnografia, observação e entrevistas, realizada no Cariri Paraibano, junto às famílias que têm casos da doença genética, buscava entender as relações engendradas entre as famílias e a genética, quando o heredograma estabelece o diagnóstico da enfermidade e a relação de parentesco. Inicialmente, os interlocutores apontam que o heredograma lhes foi apresentado para “comprovar” que existe uma relação de parentesco e o nexo causal da doença. Entretanto, tal instrumento não coincide com a perspectiva sociocultural da noção de parentesco utilizado pelas famílias. Nossa leitura é que o heredograma elaborado pela genética não tem correspondência com as questões locais, quando outros valores, como “conhecimento” entre as famílias e/ou ter origem na mesma localidade, são relevantes para constituição de novas famílias e parentesco.

Authors: Sebayang Ika Sari Damayanthi , Soekarno Indratmo , Cahyono Muhammad , Kuntoro Arno Adi
Published: November 2022

Aims:

This research aimed to determine the amount of environmental flow (EF) required to sustain the river’s function in supporting ecological balance.

Backgrounds:

In Indonesia, the Citarum area usually experiences significant environmental challenges, including the overflow of the Citarum River and its watersheds, which causes flooding, and lack of water during the dry season. However, the major challenge is the availability of water in Citarum, attributed to the discharge affecting the ecological balance of the watersheds

Methods:

A review of EF was conducted by comparing 7Q10 and Q95 from both the Nanjung discharge observation data and the rainfall-runoff modeling.

Results:

The results found that the Weibull minima method, the 7Q10 result for Sacramento modeling, was 2.18 m3/s while the Nanjung AWLR was 1.24 m3/s. Additionally, the value of Q95 for Nanjung AWLR was 7.17 m3/s, while the result of modeling rainfall-runoff was 7.06 m3/s.

Conclusions:

It is necessary to ensure that the amount of discharge available can support the ecological conditions in the Upper Citarum River Basin area. This was relevant since the difference was certainly affecting the ecological balance and the management of the Citarum River.
Experimental and Numerical Investigations on an Organic Phase Change Material Incorporated Cool Concrete Pavement
Authors: Anupam B.R. , Sahoo Umesh C. , Rath Prasenjit
Published: November 2022

Background:

Traditionally, cool pavements have been designed as reflective, evaporative, etc. Though the reflective pavements reduce the pavement surface temperature significantly, they increase glare, the thermal burden on pedestrian traffic, and the temperature of nearby buildings. In the case of evaporative pavements, the absence of water, reduced thermal inertia and solar reflection result in a higher pavement temperature. As a result, there has been a pressing need to investigate new low-side-effect cool pavement options.

Objective:

The study aims to analyze the effect of phase change material (PCM) incorporation on the thermal performance of concrete pavements and to develop a total enthalpy-based numerical heat transfer model for such cool pavements.

Materials and Methods:

A paraffin-based organic PCM with a melting point of 42 to 45 °C was used in this work, and expanded clay aggregate (ECA) was used as an encapsulation medium. Concrete slabs without and with the incorporation of PCM-impregnated ECAs were cast, and thermocouples were implanted in the concrete to monitor the pavement temperature continuously. A total enthalpy-based numerical heat transfer model was developed to predict the thermal performance of such cool concrete pavements.

Results:

The PCM incorporation reduced 2.24 °C in the annual average pavement surface temperature with a maximum reduction of 4.12 °C.

Conclusion:

PCM incorporation effectively reduces pavement surface temperature during the daytime and makes the pavements cooler. Increasing the encapsulating medium's porosity and the concrete slab's thermal conductivity enhances the cooling potential. However, the thermal characteristics of the encapsulating material may be neglected as their impact is less on the cooling potential.

Authors: Assunção Joana , Amaro Helena M. , Malcata F. Xavier , Guedes A. Catarina
Published: November 2022

Algal bioactive compounds, including pigments, polyunsaturated fatty acids, vitamins, proteins and phenolic compounds, have a wide range of increasing applications in the pharmaceutical, nutraceutical, feed, food, and cosmetics sectors. Extraction of such compounds with the purpose of obtaining nutraceutical and food ingredients at large has been under scrutiny over the last years towards greener and more sustainable bio-based processes. The step of the extraction is indeed considered the most expensive in algal-based industrial bioprocess, mainly owing to the high processing costs and environmental impacts. Therefore, the application of a biorefinery strategy (for biomass reutilization, via choice of specific green and generally recognized as safe solvent), will certainly help attain a more feasible and competitive solution. Furthermore, emerging extraction technologies are potentially suitable for application at a large scale, as part of a multi-integrated extraction strategy. This chapter accordingly addresses the most important (micro)algal-compounds possessing bioactivities, and already or likely to be used as functional ingredients; in addition, extraction procedures thereof are discussed, bearing in mind a biorefinery strategy – with major prospects and associated challenges.

Earthmoving work is often performed based on simple calculation and experience. This practice may work on a small project. However, for a big project in which a large excavation volume must be accomplished, managing the work become more complex. Some different equipment in various types and sizes need to be assigned. Project managers should determine the best combination of equipment with the correct amount to achieve a satisfactory result. This research was conducted to optimize the productivity-cost index in earthmoving works using a discrete event simulation (DES) analysis in four different schemes. An underpass project in Yogyakarta was used as the case study. The optimal combination of equipment was determined by the highest value of the productivity-cost index. The result shows that the highest productivity-cost index of 18.22 was achieved by the combination of four big excavators and 90 small trucks (2E4 90D1). It offered a better productivity-cost index compare to the contractors existing equipment combination which could only reach a productivity-cost index of 5.3.

Technological developments, especially in the construction sector, have developed rapidly. The construction industry is one of the activities that consume energy, resources, and affects the environment. Therefore it is important to increase innovation and solutions to achieve sustainability standards. Several efforts were made to maintain environmental sustainability against global problems, namely the selection of building materials through an analysis of the impact of building materials on the environment called a Life Cycle Assessment (LCA). In this study, two types of curtain wall system materials, type (A), reinforced concrete, final coating, and type (B) brick, reinforced concrete, ceramic, and mortar will be compared. The method used in the completion of this research is a full building supply system in one way, namely the collaboration between Autodesk Revit and Tally which will then be analyzed again. The first step is to determine the type of material by calculating the total material requirements to be used or by modeling the building using Autodesk Revit. From the total volume of material that will be analyzed the impact of the building life cycle based on ISO 14040. The final objective of this research is to get the best alternative from the second material above. The results of the analysis supported the type (B) material which has a smaller effect than the type (A) material on the main environment that regulates global.
Spel en betekenisgeving bij de musealisering van christelijk-religieus erfgoed
Authors: Verbeek W.P.
Published: November 2022

In Homo Ludens Johan Huizinga argues that play is a necessary condition of culture, as for example in the placement of objects in the Rijksmuseum: their arrangement produces different layers of meaning that can be uncovered in various ways by visitors. Huizinga opposes the idea of the as a museum of art because combining objects of art and historical objects will lead to a ‘historical sensationalism’. The polyptych “The Seven Works of Mercy” (De zeven werken van barmhartigheid) shows how a Christian-religious object can function in the Rijksmuseum’s environment, defined by secular rules of presentation.

Published: November 2022

El coltán, un mineral esencial para prevenir la corrosión en aleaciones especiales y de alta resistencia, es usado en general para la producción de componentes electrónicos, por lo que se considera muy estratégico en la industria tecnológica. Debido a estas propiedades y a la demanda internacional, en la última década organizaciones criminales alrededor del mundo han desatado conflictos por controlar esta commoditie, lo cual ha generado inestabilidad en muchos países, sobre todo en África, donde se encuentran las principales reservas, en contraste con Australia o Canadá, países que también son productores, pero que no sufren las consecuencias de la llamada “maldición de los recursos”. Luego de que en el año 2009 se descubrieran yacimientos de coltán en Colombia, los diversos actores criminales que ejercen un control territorial sobre algunos departamentos ricos en este recurso iniciaron procesos de explotación ilícita, con un alto costo ambiental y enormes beneficios económicos.

The situation where one can practise working from home is not easy for some people in Malaysia, especially those with limited space at home. Working from home (WFH), on the other hand, needs to be rethought and thoroughly examined for individuals in the bottom 40 percent (B40) for a variety of reasons. A total of 144 samples from low-income households in Shah Alam responded to the structured questionnaire. The questionnaire focuses on two main investigations: (1) the WFH conditions in terms of space and environment among the B40; and (2) how they manage WFH distractions in connection to the house space and environment. According to survey results, most respondents prefer working in a bedroom or living room since it is a more pleasant environment. The availability of electrical plugs, internet access, and adequate ventilation are further considerations that influence their choice of workspace. The survey’s findings indicated that the lack of a comfortable workspace made the majority of respondents unhappy about practising WFH. The majority of responders suggested that future bedrooms be larger to guarantee that those practising WFH are comfortable. The results of this study are expected to enhance the planning and design of residential living space and pave the way for future low-cost housing development that places greater emphasis on the well-being of the urban poor.

Published: November 2022

The COVID-19 pandemic has negatively impacted anti-violence centers for women. This study aims to investigate how the COVID-19 pandemic restrictions affect: the assistance and protection functions of the anti-violence centers; the needs of women victims of violence; and the well-being of the professionals working with these women. Twenty-four Italian anti-violence centers were involved, and 29 women working there were interviewed. From the qualitative analysis of the texts, three main themes were identified regarding the impact of the COVID-19 pandemic on the anti-violence centers service: 1) transformations and synergies to improve help-seeking, 2) consequences of the pandemic situation on women victims of violence, and 3) the impact of the COVID-19 crisis on professionals. The results show that anti-violence centers need to be restructured to respond to the changes caused by the pandemic and expand their remote support strategies. Their interventions were fundamental in enabling women to seek help during the COVID-19 pandemic. The professionals involved in providing support to victims encountered stressful difficulties specific to the pandemic.
Human Decision-making in an Artificial Intelligence–Driven Future in Health: Protocol for Comparative Analysis and Simulation
Authors: Doreswamy Nandini , Horstmanshof Louise
Published: November 2022

Background

Health care can broadly be divided into two domains: clinical health services and complex health services (ie, nonclinical health services, eg, health policy and health regulation). Artificial intelligence (AI) is transforming both of these areas. Currently, humans are leaders, managers, and decision makers in complex health services. However, with the rise of AI, the time has come to ask whether humans will continue to have meaningful decision-making roles in this domain. Further, rationality has long dominated this space. What role will intuition play?

Objective

The aim is to establish a protocol of protocols to be used in the proposed research, which aims to explore whether humans will continue in meaningful decision-making roles in complex health services in an AI-driven future.

Methods

This paper describes a set of protocols for the proposed research, which is designed as a 4-step project across two phases. This paper describes the protocols for each step. The first step is a scoping review to identify and map human attributes that influence decision-making in complex health services. The research question focuses on the attributes that influence human decision-making in this context as reported in the literature. The second step is a scoping review to identify and map AI attributes that influence decision-making in complex health services. The research question focuses on attributes that influence AI decision-making in this context as reported in the literature. The third step is a comparative analysis: a narrative comparison followed by a mathematical comparison of the two sets of attributes—human and AI. This analysis will investigate whether humans have one or more unique attributes that could influence decision-making for the better. The fourth step is a simulation of a nonclinical environment in health regulation and policy into which virtual human and AI decision makers (agents) are introduced. The virtual human and AI will be based on the human and AI attributes identified in the scoping reviews. The simulation will explore, observe, and document how humans interact with AI, and whether humans are likely to compete, cooperate, or converge with AI.

Results

The results will be presented in tabular form, visually intuitive formats, and—in the case of the simulation—multimedia formats.

Conclusions

This paper provides a road map for the proposed research. It also provides an example of a protocol of protocols for methods used in complex health research. While there are established guidelines for a priori protocols for scoping reviews, there is a paucity of guidance on establishing a protocol of protocols. This paper takes the first step toward building a scaffolding for future guidelines in this regard.

GSAs produce signals that provide vital information about the exposed gases for the machine learning algorithms, rendering them indispensable within the smart-gas sensing arena. In this work, we present a detailed assessment of several machine learning techniques employed for the detection of gases and estimation of their concentrations. The modeling and predictive analysis conducted in this paper are based on kNN, ANN, Decision Trees, Random Forests, SVM and other ensembling-based techniques. Predictive models are implemented and tested on three different MoX gas sensor-based experimental datasets as reported in the literature. The assessment includes a delineated analysis of the different models’ performance followed by a detailed comparison against results found in the literature. It highlights factors that play a pivotal role in machine learning for gas sensing and sheds light on the predictive capability of different machine learning approaches applied on experimental GSA datasets.

Nano-encapsulated phase change suspension is a novel type of functional fluid in which the nanoparticles undergo phase change that contribute to heat transfer. Thus, the working fluid carries heat not only by sensible heat but also in the form of latent heat stored in the particles. The natural convection and heat transfer of Nano-Encapsulated Phase Change Materials (NEPCMs) suspensions within a boundary layer along a heated flat surface are theoretically investigated in this work. The nanoparticles are core-shell structured with the core fabricated from PCMs covered by a solid shell. A similarity solution approach along with the finite element method is employed to address the phenomena. The outcomes indicate that a decisive factor in boosting the heat transfer is the temperature at which NEPCM particles undergo the phase transition. The heat transfer parameter can be enhanced by about 25% by just adding 5% of NEPCM particles, compared to the case with no NEPCM particles.

Objective: To evaluate the validity and reliability of the Diabetes Eating Problem Survey-Revised (deps-r) instrument to identify the risk of eating disorders (ed) in a Mexican population diagnosed with Diabetes Mellitus (dm). Methods: A three-stages instrument validation study. Stage 1. Translation: three translators, whose native language was Spanish, translated the English version of the deps-r instrument; Stage 2. Using the Delphi method, the validity of the content was estimated through an evaluation of five experts; subsequently the wording was evaluated applying the instrument to a pilot group of ten people; finally, the instrument was applied to a calculated sample (95% confidence interval; 5% error rate) of 130 patients. Stage 3: A psychometric evaluation was carried out, calculating Cronbach’s alpha, and Spearman’s correlation coefficients. Results: Cronbach’s alpha was 0.72. Spearman’s correlation coefficient was calculated, highlighting the weight/score ratio obtained in the second version of the deps-r with 0.3645 (p<0.0001). Conclusion: there is good reliability in the translated and validated version of the instrument, making it an adequate screening measure for the identification of ed in the Mexican population.

Objetivo: estimar la asociación entre deterioro cognitivo y obesidad en adultos. Métodos: estudio transversal analítico con una muestra no probabilística de casos consecutivos. Se incluyeron 112 participantes de 20 a 64 años de edad, con peso normal y con obesidad, que acudieron a la consulta externa del Hospital General Regional con Medicina Familiar No. 1, en Cuernavaca, Morelos, México. Se utilizó la escala de Evaluación Cognitiva de Montreal y se evaluaron covariables como actividad física, consumo calórico, sexo, edad, circunferencia de cintura y porcentaje de grasa corporal. Los datos se analizaron con el programa estadístico stata 11.1. Resultados: de los 112 participantes, 23 eran hombres y 89, mujeres; el rango de edad fue de 20 a 64 años (mediana 30 años). Se encontraron diferencias estadísticamente significativas (p<0.05) entre los grupos con y sin deterioro cognitivo en las variables: escolaridad, edad, nivel de grasa visceral, porcentaje de grasa corporal, circunferencia de cintura y calidad muscular. Después de ajustar por edad, sexo, nivel de educación, actividad física y consumo de calorías diarias, la obesidad se asoció significativamente con un incremento de la posibilidad de presentar deterioro cognitivo (rm = 3.77, ic 95% = 1.004-14.190, p <0,04). Conclusión: la obesidad se asoció con mayor posibilidad de presentar deterioro cognitivo, mientras que la escolaridad superior se asoció con una menor posibilidad de presentarlo.

Introducción: el uso empírico y amplio de profilaxis antibiótica ya  no es una práctica aceptable, pero todavía continúa siendo un problema frecuente, particularmente entre los odontólogos. Objetivo: investigar el uso empírico de antibacterianos por parte de los odontólogos del Ecuador. Material y métodos: se aplicó una encuesta  autodiseñada de ocho preguntas para evaluar conocimientos, actitudes y prácticas en entrevista cara a cara con 307 odontólogos de ocho ciudades diferentes del Ecuador (Quito, Guayaquil, Cuenca, Santo Domingo, Ibarra, Loja, Manta y Portoviejo). Los datos fueron recolectados en una base de datos electrónica y luego analizados utilizando el programa GraphPad InStat. Resultados: de los odontólogos que completaron la encuesta, sólo 32.9% tuvieron título de especialista. Cuando se preguntó tratamiento de abscesos, sólo 63.5% de los encuestados mencionaron drenaje y tratamiento endodóntico como primer paso de tratamiento. Aquellos que pretrataron a sus pacientes utilizaron amoxicilina (35.7%), amoxicilina más ácido clavulánico (25.3%) y azitromicina (14.8%). La amoxicilina en dosis de 500 mg fue utilizada sólo en 72.7% de los casos, mientras que la dosis de 625 mg de amoxicilina más ácido clavulánico fue prescrita en 64% de los pacientes. En cuanto al periodo de administración sólo 62.6% de los profesionales lo utilizaron cada 8 horas. Por último, sobre la duración del tratamiento, 84.5% de los pacientes lo recibieron por al menos siete días. Conclusiones: el sobreuso de antibacterianos por los odontólogos del Ecuador representa un problema importante que puede estar relacionado con desarrollo de resistencia bacteriana y aumento en los costos de atención. La implementación de protocolos de tratamiento puede ayudar, así como la educación continua sobre el uso de tratamiento antibacteriano.

Published: November 2022

Introducción: los tumores de células gigantes constituyen un conjunto de procesos patológicos con cierto grado de controversia en el diagnóstico, diferentes en su comportamiento, pero con características histológicas en común. El granuloma central de células gigantes (GCCG) es una lesión intraósea de tejido fibroso celular con múltiples focos hemorrágicos y agregaciones celulares gigantes nucleadas. El objetivo de este artículo es reportar las características clínicas y de imagen, abordaje y seguimiento de una paciente infantil con GCCG. Reporte de caso: se trata de paciente femenino de seis años de edad que fue referida al Servicio de Cirugía Maxilofacial del Hospital General de Zacatecas, sin antecedentes médicos relevantes. Al examen intrabucal se observó visible aumento de volumen de aspecto sésil y coloración rojiza, doloroso a la palpación, localizado en la cara interna de la mucosa labial superior y frenillo, que se extendía hacia el canino derecho, causando una franca asimetría en la porción anterior del paladar duro. Tras la realización de estudios de imagen (radiográficos y Cone Beam) se realizó la extirpación quirúrgica de la lesión bajo anestesia general y se confirmó histológicamente el granuloma de células gigantes. Conclusión: en las lesiones orales la elección del tratamiento está influenciada por el comportamiento clínico de la lesión. La detección temprana permite un abordaje conservador.

Published: November 2022

La clasificación de enfermedades periodontales del año 1999 estuvo vigente durante 18 años, por lo que en 2017 se realizó un taller mundial, donde expertos periodontales de todo el mundo, con el copatrocinio de la Academia Americana de Periodontología (AAP) y de la Federación Europea de Periodontología (EFP), se reunieron para actualizar y presentar una nueva clasificación conforme se ha ido expandiendo la evidencia basada en investigaciones científicas. Se dividieron en cuatro grupos de trabajo consistentes en: I salud periodontal, enfermedades y condiciones gingivales. II Formas de periodontitis. III manifestaciones periodontales de las enfermedades sistémicas y condiciones del desarrollo y adquiridas. IV Enfermedades condiciones periimplantarias. En esta segunda parte se abordarán las principales definiciones y parámetros del grupo III (manifestaciones periodontales de las enfermedades sistémicas y condiciones del desarrollo y adquiridas), donde se incluye a las enfermedades sistémicas que ocasionan daño directo a los tejidos periodontales sanos, a los abscesos periodontales y las lesiones endodóncicas-periodontales, clasificándolos según si existe o no presencia de periodontitis. También se considera el cambio del término biotipo por fenotipo periodontal y una nueva clasificación de las recesiones gingivales, la cual evalúa su severidad a partir de la pérdida de la inserción interproximal. Asimismo, se revisa el grupo IV (enfermedades y condiciones periimplantarias) donde se describe la salud periimplantaria, la mucositis periimplantaria y la periimplantitis, y las deficiencias de tejidos blandos y duros.
