RESUMO
Introduction: Excessive gummy smile affects the aesthetics of the patient and can be the result of several factors, including altered passive eruption, which can be surgically corrected by aesthetic crown lengthening. Case report: 22-year-old female patient, who was treated by aesthetic crown lengthening for the correction of type 1B altered passive eruption. Discussion: Considering the patient's age and periodontal phenotype, surgical correction of the gummy smile by aesthetic crown lengthening shows stable long-term results. Conclusion: Surgically correcting excessive gingival exposure through esthetic crown lengthening can help patients improve the appearance of their smile and regain their self-confidence.

Abstract Introduction The COVID-19 pandemic has negatively impacted physical and mental health worldwide. It is essential to continue exploring the population's psychological manifestations and the pandemic's impact on lifestyles (physical activity, quality of sleep). Objective This research aimed to describe the relationship between affect (positive and negative) and physical activity (PA) in college students during the COVID-19 pandemic. Method A cross-sectional survey was conducted on health sciences students from three universities in Mexico and Colombia. PA was assessed using the short version of the International Physical Activity Questionnaire (IPAQ-S), and affects were measured using the PANAS index. A logistic regression model was used to assess the association between PA and affect. Results We included 430 participants between 16 and 40 years. We found no differences between the male and female participants regarding age, weight (BMI), PA, or the number of hours of sitting per day. The monthly consumption of alcohol and tobacco was more frequent in males (p < .05), and women expressed having worse sleep quality (p < .05). Adjusting for the number of hours spent sitting per day, gender, BMI, age, sleep quality, smoking and alcohol consumption habits, participants reported having more positive affect when they engaged in greater PA. No association was found between PA and negative affect. Discussion and conclusion Prioritizing mental health and assessments that determine the late impact of the COVID-19 pandemic on psychological well-being is critical. Promoting PA in university communities is considered a priority to positively impact students' mental health and provide tools to facilitate coping.
Resumen Introducción La pandemia de COVID-19 impactó negativamente la salud tanto física como mental a lo largo del mundo. Es importante identificar las manifestaciones psicológicas de la población y el impacto de la pandemia en los estilos de vida (actividad física, calidad del sueño). Objetivo Describir la relación entre el afecto (positivo y negativo) y la actividad física (AF) en estudiantes universitarios durante la pandemia de COVID-19. Método Se realizó una encuesta transversal a estudiantes de ciencias de la salud pertenecientes a tres instituciones de educación superior en México y Colombia. La AF se evaluó mediante la versión corta del Cuestionario Internacional de Actividad Física (IPAQ-S), y los afectos se midieron mediante el Índice PANAS. Se utilizó un modelo de regresión logística para evaluar la asociación entre AF y afectos. Resultados Se incluyeron 430 participantes entre 16 y 40 años. No encontramos diferencias entre hombres y mujeres en cuanto a edad, peso (IMC), nivel de AF ni el número de horas sentados por día, sin embargo, el consumo mensual de alcohol y tabaco fueron más frecuentes en hombres (p < .05) y las mujeres expresaron tener peor calidad de sueño (p < .05). Al ajustar por la cantidad de horas que pasaban sentados por día, el género, IMC, edad, calidad del sueño y los hábitos de consumo de tabaco y alcohol, los participantes expresaron tener más afectos positivos cuando realizaban mayor AF, sin embargo, no encontramos asociación entre AF y los afectos negativos. Discusión y conclusión Es fundamental priorizar la salud mental y las evaluaciones que determinan el impacto tardío de la pandemia de COVID-19 en el bienestar psicológico. Se considera necesario promover la AF en las comunidades universitarias para impactar positivamente en la salud mental de los estudiantes y brindar herramientas que faciliten el afrontamiento.
RESUMO
The data presented in this article are complementary material to our work entitled "A decision support system for prioritization of patients on surgical waiting lists: A biopsychosocial approach". We prepared, together with physicians, a survey was used in the otorhinolaryngology unit of the Hospital of Talca for a period of five months, between February 05, 2018 and June 29, 2018. Two hundred and five surveys were collected through 20 biopsychosocial criteria, which allowed measuring the priority and vulnerability of patients on the surgical waiting list. The data allow choosing and preparing patients for surgery according to both a dynamic score and a vulnerability level.
RESUMO
Recent studies show that the process of extraction of olive oil results in a large amount of waste. Around 20% the oil is obtained in the process and the remaining 80% corresponds to mainly two types of waste, known as orujo and alperujo. These residues were stored in pools for 6 months in an uncontrolled environment. The reservoirs are open and generate Odorous Volatile Organic Compounds (VOCs) as products of waste decomposition. The data in this article corresponds of physical-chemical compounds of olive oil mill waste exposed to ambient conditions. The data was obtained from two different oil mills, namely, Almazara del Pacífico located in the Alto Pangue area, Talca, Chile; and Agricola y Forestal Don Rafael oil mill, Molina, Chile. Samples were extracted directly from the oil mills to fill 200 L plastic containers that simulated the waste storage in oil mill reservoirs. Each sample was identified and standardized to a mass of 150 kg and moved and stored under uncontrolled ambient conditions at the Universidad de Talca, Curicó, Chile.
RESUMO
Canopy temperature (Tc) by thermal imaging is a useful tool to study plant water status and estimate other crop traits. This work seeks to estimate grain yield (GY) and carbon discrimination (Δ13C) from stress degree day (SDD = Tc - air temperature, Ta), considering the effect of a number of environmental variables such as the averages of the maximum vapor pressure deficit (VPDmax) and the ambient temperature (Tmax), and the soil water content (SWC). For this, a set of 384 and a subset of 16 genotypes of spring bread wheat were evaluated in two Mediterranean-climate sites under water stress (WS) and full irrigation (FI) conditions, in 2011 and 2012, and 2014 and 2015, respectively. The relationship between the GY of the 384 wheat genotypes and SDD was negative and highly significant in 2011 (r2 = 0.52 to 0.68), but not significant in 2012 (r2 = 0.03 to 0.12). Under WS, the average GY, Δ13C, and SDD of wheat genotypes growing in ten environments were more associated with changes in VPDmax and Tmax than with the SWC. Therefore, the amount of water available to the plant is not enough information to assume that a particular genotype is experiencing a stress condition.
