Resumen Este artículo aborda el análisis del récord crediticio y su importancia de mantenerlo en excelentes condiciones en época de pandemia por efecto del Covid19. El estudio tiene un enfoque mixto, mediante análisis descriptivo y transversal, con base en un estudio de campo efectuado a una muestra de 250 personas como clientes de las más importantes instituciones financieras de la ciudad de Riobamba (Chimborazo Ecuador), para exponer y ejemplificar los resultados del diagnóstico, apoyado en revisión bibliográfica-documental. Los resultados revelan que el 74% de los encuestados conocen su récord crediticio, la falta de pago de sus obligaciones en época de pandemia afectarán su historial crediticio pues el 82% lo afirman y el 70% de los encuestados confirman que es importante tener un excelente récord crediticio. Se concluye por tanto que es importante disponer de un excelente récord e historial crediticio en las entidades financieras y comerciales, si se desea obtener futuros beneficios crediticios, para sus actividades empresariales y personales.

Abstract This article addresses the analysis of the credit record and its importance of keeping it in excellent condition in times of a pandemic due to Covid19. The study has a mixed approach, through descriptive and cross-sectional analysis, based on a field study carried out on a sample of 250 people as clients of the most important financial institutions in the city of Riobamba (Chimborazo Ecuador), to expose and exemplify the results of the diagnosis, supported by bibliographic-documentary review. The results reveal that 74% of respondents know their credit record, failure to pay their obligations in times of a pandemic will affect their credit history as 82% affirm it and 70% of respondents confirm that it is important to have an excellent credit record. It is therefore concluded that it is important to have an excellent record and credit history in financial and commercial entities, if you want to obtain future credit benefits for your business and personal activities.

Abstract Robust epidemiological data allow for logical interventions taken in the interest of public health. Dental caries is a major public health problem driven by increased sugar consumption and various biological, behavioral, and psychosocial factors, and is known to strongly affect an individual’s quality of life. This study aims to critically review epidemiological data on the prevalence of dental caries in Latin American and Caribbean countries (LACC) and its impact on the oral health-related quality of life (OHRQoL) of the population. Although the majority of national surveys did not include all age groups and several countries reported a reduction in the prevalence of cavitated carious lesions, most nations still exhibited a high burden of decayed teeth. OHRQoL evaluation was limited to children and older adults only, and was not included in any national survey. Study heterogeneity and methodological issues hindered comparison of evidence between studies and over time, and updating national level data on caries prevalence and its impact on OHRQoL should be prioritized in LACCs.

RESUMO Embora antes da pandemia houvesse alguma resistência à virtualização da educação odontológica, a pandemia COVID-19 está nos fornecendo uma oportunidade única de superar várias barreiras que anteriormente bloqueavam a adoção do ensino à distância e teledontologia. Graças à ampla disponibilidade de telecomunicações, tecnologias digitais e plataformas, a educação à distância e a teledontologia parecem ser a escolha preferida para manter a educação odontológica e o atendimento ativo aos pacientes durante a pandemia, sem riscos de contaminação. Neste artigo, revisamos estratégias válidas de educação a distância e possíveis alternativas úteis na transformação virtual na educação odontológica. Além disso, o papel do teleodontologia e suas vantagens, assim como também os desafios. No atual contexto pandêmico, como educadores odontológicos, somos chamados a ser criativos e flexíveis. Cada escola de odontologia deve se adaptar e usar a educação à distância, tanto quanto possível, até que a atenção clínica possa ser readotada. As evidências apresentadas nesta revisão corroboram nossa posição de que, sob esta pandemia, a educação a distância e a telemedicina / teleodontologia podem ser “a solução virtual conveniente”, para adaptar e aprimorar a forma até então clássica de ensino de odontologia, agora por meio da teleducação.

ABSTRACT Although prior to the pandemic there was some resistance to the virtualization of dental education, the COVID-19 pandemic is providing us a unique opportunity to overcome several barriers that previously blocked the adoption of remote teaching and teledentistry. Thanks to the extended availability of telecommunications, digital technologies, and platforms, remote education and teledentistry appear to be the preferred choice to maintain dental education and patient care active under this pandemic, without contamination risks. In this paper, we review valid remote education strategies and possible alternatives useful in virtual transformation in dental education. Furthermore, the role of teledentistry and its advantages and challenges are also revised. Under the current pandemic context, as dental educators, we are called to be creative and flexible. Every dental school should adapt and use remote education as much as possible until clinical attention can be readopted. The evidence presented in this review supports our position that under this pandemic, remote education and telemedicine/teledentistry may be “the virtual convenient solution”, to adapt and improve the hitherto classic way of teaching dentistry through tele-education.

SUMMARY Coronavirus disease (COVID-19) is highly transmissible through respiratory droplets, saliva, and aerosol particles. Infection can lead to severe acute respiratory syndrome and trigger multi-organ failure and death. Most clinical dental procedures involve contact with saliva or the generation of aerosols with saliva and blood. These airborne particles increase the risk of transmission by COVID-19 between dentists and patients. Thus, dentistry must adopt procedures to reduce transmission during dental procedures. Although these strategies may not be directly applicable to all institutions due to cultural, social, geographical, and economic differences, the underlying principles and implemented strategies remain relevant and can be adopted or modified by the institutions dealing with the current COVID-19 outbreak. The purpose of this article is to discuss one of the principal sources of COVID-19 transmission: saliva, the biofluid most frequently handled in a radiology environment. The authors also recommend strategies and operational procedures to decrease the spread of COVID-19 in a radiological routine.

RESUMEN La enfermedad por coronavirus (COVID-19) se transmite fácilmente a través de gotitas respiratorias, saliva y partículas de aerosol. La infección puede desencadenar un síndrome respiratorio agudo severo, insuficiencia multiorgánica y, en algunos casos, la muerte. Los procedimientos clínicos dentales determinan el contacto con saliva o la generación de aerosoles con saliva y sangre, lo que implica un alto riesgo de transmisión por COVID-19 entre odontólogos y pacientes. Por ello, la práctica odontologica debe adoptar medidas para detener la propagación durante los procedimientos dentales. En este artículo se revisan las estrategias para mitigar el riesgo de transmisión de COVID-19. Si bien estas estrategias pueden no ser directamente aplicables a todas las instituciones debido a diferencias culturales, sociales, geográficas y económicas inherentes, los principios subyacentes y las estrategias implementadas siguen siendo relevantes y pueden ser adoptados o modificados por las instituciones que se ocupan del brote actual de COVID-19. El propósito de este artículo es discutir una de las principales fuentes de transmisión de COVID-19: la saliva, el biofluido que se maneja con mayor frecuencia en un entorno radiológico. Los autores también recomiendan estrategias y procedimientos operativos para disminuir la propagación de COVID-19 en una rutina radiológica.

RESUMO Objetivo: O objetivo deste estudo foi investigar o impacto das lesões de desgaste dentário erosivo na qualidade de vida relacionada à saúde bucal (QVRSB) de pré-escolares. Métodos: Exames clínicos foram conduzidos em 815 crianças de 3 e 4 anos de idade durante a Campanha Nacional de Multivacinação Infantil. Os pais ou responsáveis foram convidados a responderam a versão brasileira do Early Childhood Oral Health Impact Scale (B-ECOHIS). A prevalência e a gravidade das lesões de desgastes dentários erosivos foram avaliadas de acordo com o índice de O’Brien (1994). Também foram coletados dados socioeconômicos e variáveis da criança. A QVRSB foi mensurada por meio dos domínios e escore total do B-ECOHIS. A análise de regressão de Poisson foi adotada para associar as lesões de desgaste dentário erosivo ao desfecho e ajustada para cárie dentária e lesões dentárias traumáticas. Resultados: A proporção de crianças que apresentavam pelo menos 1 dente apresentando desgaste dentário erosivo foi 51,2%. A maioria das lesões de desgaste dentário erosivo estava confinada ao esmalte (42,7%). A análise ajustada multivariada revelou que apenas que a idade (crianças de 4 anos) foi associada a um impacto negativo nos domínios de sintomas (RR=1,70; p=0,010), limitação funcional (RR=1,85; p=0,005) e escore total do B-ECOHIS (RR= 1,63; p=0,006). Famílias com 2 ou mais filhos tiveram um impacto negativo nos dominíos de autoestima e interação social (RR=5,41; p=0,043). As lesões de desgaste dentário erosivo não foram associadas ao escore total de B-ECOHIS (RR= 0,79; p=0,163) e domínios individuais. Conclusão: As lesões de desgaste dentário erosivo não afetaram a qualidade de vida de pré-escolares da amostra estudada.

ABSTRACT Objective: The aim of this study was to investigate the impact of erosive tooth wear on the Oral Health-Related Quality of life (OHRQoL) of preschool children. Methods: Dental examinations were conducted on 815 children aged 3-4 years during the Children’s Vaccination National Day when their parents were also invited to answer the Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS). ETW prevalence and severity were measured using a modified version of the O’Brien index (1994). Data collected included socioeconomic factors and child's variables. OHRQoL was measured through B-ECOHIS domains and total score. Poisson regression was used to associate ETW to the outcome and this association was adjusted for dental caries and dental trauma. Results: The proportion of children who had at least 1 ETW tooth was 51.2%. Most erosive lesions were confined to enamel (42.7%). The multivariate adjusted model showed that child's age (children aged 4year-old) was associated to a negative impact on the symptom domain (RR=1.70; p=0.010), functional limitation domain (RR=1.85; p=0.005) and total B-ECOHIS score (RR= 1.63; p=0.006). Families with 2 or more children in the house have a negative impact on the self-image/social interaction domain (RR=5.41; p=0.043). ETW was not associated to total B-ECOHIS scores (RR= 0.79; p=0.163) and individual domains. Conclusion: Erosive tooth wear does not affect the OHRQoL in this sample of preschool children.

Abstract Structural vulnerability from dynamic pressures due to the impact of lahars is analyzed in the town of Santiago Xalitzintla (Mexico). The process of vulnerability assessment was conducted independently from the hazard (lahar). For this end, every building was classified. The typification was developed taking into account the materials used in the construction of buildings, and how they contribute to its strength in two ways. a) Based on field work, by visiting the place in order to identify typologies and possible critical areas. b) By using the Google Earth´s Street View tool as a complement, since it was not possible to identify all the structures in the visit due to several limiting factors in the direct recognition. The vulnerability was carried out in a semi-quantitative way, based on several researches which were used to elaborate a structural vulnerability map for total damage. We identified that 62 % of the edifications have low vulnerability, 16 % have medium vulnerability and the remaining 12 % have high vulnerability. However, there were some buildings that could not be identified (around 10 % of total) and were labeled as “no data”. By using total destruction probability curves, potential situations were made for Santiago Xalitzintla. From these curves, it is clear that the total destruction probability of the structures according to their type, changes depending of their dynamic pressures, whereby it is possible to evaluate different vulnerability scenarios on the locality.

Resumen Se analiza la vulnerabilidad estructural a partir de presiones dinámicas debidas al impacto por lahares en la población de Santiago Xalitzintla (México). El proceso de determinación de la vulnerabilidad se realizó de manera independiente a la amenaza (lahar), razón por la cual, se hizo una clasificación para todas y cada una de las construcciones. La tipificación se desarrolló teniendo en cuenta los materiales empleados en la construcción de las edificaciones, y cuánto éstos aportan a su resistencia, de dos maneras. a) Mediante trabajo de campo, con el fin de identificar las características estructurales y las posibles zonas críticas en el lugar. b) Utilizando la herramienta Street Viewde Google Earth como complemento, ya que por diversos factores limitantes durante el reconocimiento directo, no fue posible la identificación de la totalidad de las estructuras. La vulnerabilidad se estableció de manera semi-cuantitativa, teniendo como base varios estudios que permitieron elaborar un mapa de vulnerabilidad estructural ante daño total para la población, donde se identificó que el 62 % de las edificaciones poseen una vulnerabilidad baja, el 16 % una vulnerabilidad media y el 12 % una vulnerabilidad alta. Sin embargo, no se lograron identificar algunas construcciones (aproximadamente el 10 % del total) a las cuales se les asignó el rotulo “sin datos”. Mediante el empleo de curvas de probabilidad de destrucción total se elaboraron potenciales situaciones para Santiago Xalitzintla. En éstas, se evidencia que la probabilidad de destrucción total de las estructuras, según su tipología, cambia de acuerdo a las presiones dinámicas, con lo cual es posible evaluar diferentes escenarios de vulnerabilidad en la localidad.

Résumé: Les fausses promesses de mariage sont l'objet de cette recherche basée sur les archives du tribunal ecclésiastique de l ́évêché du Michoacán. Les femmes y dénoncent ceux qui ont porté atteinte à leur honneur et cherchent à les obliger à se marier comme convenu ou bien à obtenir d'eux une dote. Les différents cas montrent l'importance du mariage à cette époque et les stratégies mises en place aussi bien par les hommes que par les femmes, pour avoir gain de cause. Les femmes reprennent le discours alors en vigueur invoquant leur faiblesse et leur vulnérabilité pour expliquer qu'elles ont été «trompées» par les hommes qui en ont profité pour avoir des relations sexuelles avant le mariage. Les hommes, outre le fait de nier l'acte sexuel, les traitent de «peu intègres» et recourent non seulement aux valeurs morales, mais profitent également de la situation socioéconomique qui les oblige à sortir de chez elles pour travailler, afin de les accuser de libertinage.

Abstract: This paper aims to study the unfulfillment of marriage promises based on cases registered in the Taximaroa ecclesiastical court in the Michoacán bishopric. Women who complained aimed to denounce that their honour was sullied following the unfulfilled marriage, or alternatively, to claim a compensation dowry. Such cases help to understand the importance of marriage back then, as well as the strategies used by plaintiffs, either men or women, in order to win the case. For instance, women pretended to be appear as weak, vulnerable and "cheated on" with respect to men, who allegedly took advantage of them in order to have sexual relations. The defendants did not only refuse these accusations but also labeled women as dishonest and libertines.

Resumen: La presente investigación tiene como objetivo estudiar la falta a la palabra de matrimonio a partir de los casos del juzgado eclesiástico de Taximaroa en el obispado de Michoacán. Los fines que persiguen las mujeres que demandan es denunciar su honor mancillado a través de la celebración del matrimonio prometido o en su defecto el beneficio económico de una dote. A través de estos casos también se pueden puntualizar la importancia del matrimonio en aquella época y las estrategias que hombres y mujeres empleaban para obtener el fallo a favor en las demandas de esponsales. Al respecto, las mujeres se insertaban en el discurso de la época haciéndose pasar por débiles, vulnerables y "engañadas" ante los hombres, quienes se aprovechaban de eso para tener relaciones sexuales con la promesa de matrimonio. Los hombres demandados, más allá de negar el acto sexual, tildaban a aquellas de "poco íntegras" utilizando toda clase de recursos que iban más allá de los valores morales, señalando incluso que la propia situación socioeconómica, que las llevaba a salir de su casa para trabajar, era motivo para acusarlas de libertinas.

The aim of this study was to perform a preliminary validation of an instrument designed to assess mentalization in adults (Method for Evaluation of Mentalization in the Interpersonal Context, MEMIC). A sample of 97 students (72% women) and a sample of 10 patients (50% women) participated in the study. They completed the MEMIC and some other measures of empathy, theory of mind and attachment. The results of the factor analysis suggested a two-dimensional structure (mentalizing thoughts/mentalizing feelings and several other mental states that underlie behavior) that explained 75,26% of the variance. The internal consistency was high, and inter-rater reliability was adequate. Regarding validity, the total score of the instrument showed high correlations with reflective function scores, and significant correlations with empathy, attachment and theory of mind. Furthermore, it showed capacity to differentiate patients with borderline personality disorder from the general population.

Una muestra de 97 estudiantes (72% mujeres) y una muestra de 10 pacientes (50% mujeres) participaron en el estudio. Los participantes completaron el MEMCI junto con medidas de empatia, teoría de la mente y apego. El análisis factorial sugirió una estructura de dos dimensiones (mentalización de pensamientos/mentalización de sentimientos y de otros estados mentales subyacentes a la conducta) que explicaban el 75,26% de la varianza. La consistencia interna fue alta y el acuerdo entre jueces adecuado. En cuanto a la validez, la puntuación total del instrumento correlacionó alto con las puntuaciones en función reflexiva. También correlacionó significativamente con empatía, apego y teoría de la mente. Asimismo, diferenció pacientes con trastorno límite de personalidad de la población normal.

Objective: To determine the usefulness of lactate as a prognostic factor of death in severe sepsis. Setting: Hospital Regional Docente de Trujillo. La Libertad. Perú. Material and Methods: A case control study nested in a cohort. We studied a total of 82 adult patients with severe sepsis during the period from June 2012 to April 2013 in whom we determined the usefulness of the lactate level by calculating the Positive and Negative Likelihood Ratio, Relative Risk, Positive and Negative Predictive Value, Sensibility and Specificity. The exposed cohort was constituted by those patients who presented a lactate > 2 mmol/l and the unexposed cohort by those with lactate < 2 mmol/l. Results: Overall mortality was of 54.9 % of the patients, being 92.7% in the group of cases and 17.1% in the group of controls respectively. We found a Sensitivity of 84.4% (CI: 72.7 - 96.1), a Specificity of 91.9% (CI:81.7 - 100.0), a Positive Predictive Value of 92.68% (CI: 83.5 - 100-0), a Negative Predictive Value of 82.9 (CI: 70.2 - 95.7), a Positive Likelihood Ratio of 10.4 (CI: 3.5 - 31.0), a Negative Likelihood Ratio of 0.2 (CI: 01 - 0.3) and a Relative Risk of 5.4 (CI: 2.8 - 10.7). Conclusion: Cancer, COPD, peripheral arterial disease, diabetes, heart failure, impaired baseline functional status; and overall burden of comorbidity are the main risk factors associated with hospital complications in older adults.

The literature reports that dental caries can cause functional, physical and aesthetic impairment, often with repercussions on children's general health at an early age. Moreover, recent studies have investigated how caries lesions can compromise children's quality of life. This paper aims to describe the current situation of dental caries prevalence in children and how this oral health disease can impact their quality of life.

Objectives: The goal of this study was to assess the impact of left ventricular diastolic filling on remodeling and survival after acute myocardial infarction. Methods: We studied 36 patients with first acute myocardial treated with thrombolytic agents. A Doppler echocardiography was performed at 24 hours, 30 and 90 days after infarction. It measured the relation between E and A waves peak velocities (E/A ratio) and of the E deceleration time (EDT, ms), as well as the flow propagation velocity using color mode M and the E'-wave by tissular Doppler at the lateral mitral ring. Results: Patients were divided into three groups. Group I, restrctive filling (deceleration time < 140 ms, E/FPV > 2, E/A > 2 and E/E' > 15). Group II, elevated filling pressure (deceleration time > 140 ms, E/FVP > 2, E/A 1,2 and E/E' < 15). Group III, normal filling pressure (deceleration time > 140 ms, E/FVP < 2, E/A < 1 and E/E' < 15). The E/FPV showed a better correlation in the group with restrictive filling and left ventricular filling pressure was significantly greater than in the group with normal filling pressure at 90 days (2.18 ± 0.90 vs. 1.5 ± 0.35; r = 0.99; P = .0001). The end diastolic volume (EDV) was similar in the three groups 24 hours after infarction. EDV varied at 90 days after infarction in those patients that underwent successful coronary angioplasty. Group I, 142.48 ± 32 vs. 112.48 ± 32, r = 573; P < .0001). Conclusions: E/FVP, using color M-mode Doppler echocardiography, estimates left ventricular filling pressure and predicts left ventricular dilation after acute myocardial infarction.

Objetivo: Valorar mediante ecocardiografía el impacto de la presión diastólica ventricular izquierda como predictor en la remodelación cardíaca y la supervivencia después de un infarto agudo de miocardio. Métodos: Se estudió a 36 pacientes con un primer infarto agudo de miocardio trombolizados. A todos se les realizó un estudio ecocardiográfico Doppler a las 24 h, 30 días y 90 días después del infarto. Se midieron la relación de la velocidad de la onda E/la velocidad de la onda A (E/A), el tiempo de desaceleración de la onda E (TD [ms]), la propagación de flujo transmitral por modo M color y la onda E' por Doppler tisular del anillo mitral lateral. Resultados: Se dividió a los pacientes en 3 grupos: grupo I: restrictivo (TD < 140 ms, E/Vp > 2, E/A > 2, E/E' > 15; grupo II: presiones de llenado elevado (TD > 140 ms, E/Vp > 2, E/A 1,2, E/ E' < 15), y grupo III: presiones de llenado normal (TD > 140 ms, E/Vp < 2, E/A < 1, E/E' < 15). La E/Vp mostró una mejor correlación en el grupo con llenado restrictivo y presión de llenado ventricular izquierdo mayor que el grupo con presión de llenado normal a los 90 días (media ± desviación estándar, 2,18 ± 0,90 frente a 1,5 ± 0,35; r = 0,99; p = 0,0001). El volumen diastólico final (VDF) fue similar en los 3 grupos 24 h después del infarto. El VDF varió 90 días después del infarto en quienes se realizó una angioplastia coronaria transluminal percutánea exitosa: grupo I, 142,48 ± 32 frente a 112,48 ± 32 (r = 573; p < 0,0001). Conclusiones: La E/Vp, utilizando el Doppler color en modo M, estima la presión diastólica final del ventrículo izquierdo y predice la dilatación ventricular después del infarto agudo de miocardio.
