ABSTRACT Objective: Follicular thyroid carcinoma (FTC) is less frequent but has a worse prognosis than papillary carcinoma. The available evidence on pre-operative characteristics of FTC is controversial. Our objective was to characterize the clinical, ultrasound and histopathological presentation of FTC patients treated Chile. Subjects and methods: Retrospective analysis of 97 patients treated for FTC in 6 large centers in Chile. We analyzed their ultrasonographic features and classified the nodules according to ATA risk of malignancy and TI-RADS score, as well as the cytological findings according to the Bethesda system. We described their clinical and histopathological findings at diagnosis and classified their risk of recurrence and mortality according to ATA 2015 recurrence risk category and the eighth edition of the AJCC/UICC staging system, respectively. Results: Median age was 48 years and 73.2% were females. The median diameter was 38.8 mm; only 9.5% of them were microtumors. According to ATA risk of malignancy, 86% of the nodules were low or intermediate suspicious, while 78% were category 3 or 4A nodules according to the TI-RADS. Regarding the Bethesda system, 65.9% had indeterminate cytology (20.6% category III and 45.3% category IV). At histological examination, most were minimally-invasive and angio-invasive tumors with less than 4 foci (54.7% and 28.4% respectively). More than 90% of FTC were unifocal and there was no lymphovascular or extrathyroidal invasion or lymph node involvement. Four patients (4.1%) had distant metastases at diagnosis. Most patients (95%) had stage I or II disease according to the AJCC/UICC staging system, while the risk of recurrence was low at 51.5% when using the ATA risk of recurrence scale. Conclusions: At diagnosis, most FTCs were nodules of low or intermediate suspicion at ultrasound, nearly two thirds had indeterminate cytology according to the Bethesda system, and nearly 50% of them were of low risk of recurrence.

RESUMEN: La simulación es un recurso ampliamente utilizado en los procesos formativos en odontología, especialmente para adquirir destrezas motrices y potencialmente en el desarrollo de la autoeficacia. Objetivo: Evaluar el efecto de la simulación háptica en la autoeficacia académica de odontólogos en formación. Materiales y métodos: Este estudio se centró en estudiantes de un curso de anticipación disciplinar (n=134). Se aplicó la escala de autoeficacia general después de dos actividades de tallado con apresto tradicional, mediadas por una sesión de tallado con simulación háptica. Resultados: Al determinar el rol de las dimensiones de autoeficacia en dos actividades de simulación tradicional (ABT1 y ABT2), mediadas por la háptica se obtuvo un promedio de ABT1: x̄=3,27 (n=123) y de ABT2: x̄=3,20 (n=105). De los diez ítems de la escala, hubo diferencia estadística respecto a la disminución del grado de autoeficacia en el Nº1 (p=0,05) y Nº6 (p=0,01). Conclusiones: Se puede establecer que, al utilizar un simulador háptico de manera complementaria a las de apresto tradicional, la intervención influye en la autoeficacia, puesto que se adquiere mayor conciencia de las complejidades asociadas, debiendo desafiar su propia autorregulación para hacerles frente.

ABSTRACT: Simulation is a widely used resource in dental training processes, especially to acquire motor skills and potentially in the development of self-efficacy. Objective: To evaluate the effect of haptic simulation in the academic self-efficacy of dentists in training. Materials and methods: This study focused on students of a curricular anticipatory course (n=134). The general self-efficacy scale was applied after two carving activities with a traditional approach, complemented by a carving session with haptic simulation. Results: When determining the role of the self-efficacy dimensions in two traditional simulation activities (ABT1 and ABT2) complemented by haptics, we obtained an average of ABT1: x̄=3,27 (n=123) and ABT2: x̄=3,20 (n=105). Of the ten items of the scale, there was a statistical difference regarding the decrease in the degree of self-efficacy in Nº1 (p=0,05) and Nº6 (p=0,01). Conclusions: It can be established that complementing traditional training with a haptic simulator influences self-efficacy, since the students become more aware of the associated complexities, and need to challenge their own self-regulation to deal with them.

RESUMEN Introducción: La reabsorción condilar posterior a la cirugía ortognática es una entidad clínica que afecta a la articulación temporomandibular, con consecuencias funcionales y estéticas para el paciente. En la actualidad, la determinación del riesgo de la reabsorción condilar en la etapa prequirúrgica sigue sin estar clara. Este artículo, de carácter descriptivo, buscó determinar las variaciones anatomorfológicas de la articulación temporomandibular en pacientes sometidos a cirugía ortognática. Materiales y métodos: Se tomaron y analizaron tomografías computarizadas de haz cónico en dos etapas operativas, un mes antes de la cirugía (T0) y tres meses después (T1). Se analizaron los espacios articulares, anchos corticales y sitios con reabsorción total en un total de 58 articulaciones. Resultados: Se observó una disminución media estadísticamente significativa en el grosor cortical (p < 0,05) para los diferentes sitios en los planos coronal y sagital. Todos los espacios articulares mostraron espesor reducido en el plano sagital, estadísticamente significativo para los espacios superior y posterior. Discusión: Los sitios con un ancho cortical más bajo en T0 parecían ser más susceptibles a la reabsorción. La evaluación prequirúrgica de la articulación temporomandibular juega un papel fundamental en la prevención de la reabsorción condilar en pacientes que van a ser sometidos a cirugía ortognática.

ABSTRACT Introduction: Condylar resorption of the temporomandibular joint after orthognathic surgery is a clinical entity with functional and aesthetic consequences for the patient. The determination of the risk of condylar resorption in the presurgical stage remains unclear. This article, descriptive in its nature, sought to determine anatomorphological variations of the temporomandibular joint in patients undergoing orthognathic surgery. Material and methods: Cone Beam CT scans were analysed in two operative stages, one month before surgery (T0) and three months after (T1). Joint spaces, cortical widths and sites with total resorption were analysed on 58 joints. Results: A statistically significant mean decrease in cortical thickness (p < 0.05) was observed for the different sites in the coronal and sagittal planes. All joint spaces showed reduced thickness in the sagittal plane, statistically significant for the superior and posterior spaces. Conclusions: Sites with a lower cortical width on T0 seemed more susceptible to resorption. The presurgical evaluation of the temporomandibular joint plays a fundamental role in preventing condylar resorption in patients undergoing orthognathic surgery.

Background: A low education level has been associated with cognitive impairment in older adults. Aim: To determine the association between educational attainment and suspicion of cognitive imparirment in older Chilean population. Material and Methods: Data from 2,005 adults aged ≥ 60 years assessed during 2016-2017 Chilean National Health Survey were included. Education was self-reported and categorized as primary: ≤ 8 years; secondary: 9 to 12 years and beyond secondary: > 12 years. suspicion of cognitive imparirment was assessed with the Mini-Mental questionnaire. Results: Men and women with low education attainment had a higher prevalence of cognitive impairment (33% [95% confidence intervals (CI): 24; 41] and 27% [95% CI: 21; 33], respectively). Men who reported less schooling (≤ 8 years) were more likely to be at risk of suspicion of cognitive imparirment (Odds ratio (OR): 4.53 [95% CI: 1.10, 18.62]) compared to their peers. Women showed a substantially higher magnitude of association than men. The probability of suspicion of cognitive imparirment increased 9-times (OR: 9.96 [95% CI: 1.24; 79.6]) for 9-12 years and 18-times for ≤ 8 years of education (OR: 18.8 [95% CI: 2.42; 146.1]) compared to women with higher education. Conclusions: Older adults with low education attainment had an increased likelihood of developing suspicion of cognitive imparirment. However, the risk differs by sex, being higher in women than men.

Background: Cardiorespiratory fitness (CRF) is inversely associated with metabolic diseases and adiposity markers. Aim: To assess the association of CRF with body mass index (BMI), waist circumference (WC) and obesity in a representative sample of the Chilean population. Material and Methods: Data from 5,958 participants in the Chilean National Health Survey 2016-1027 aged 15 years or above were analyzed. CRF was estimated by an equation that included sociodemographic, anthropometric and health-related data and expressed in metabolic equivalent units (METs). The association between CRF and adiposity was assessed using linear and Poisson regression models and the results were presented as Prevalence Ratio (PR). Results: One MET increment in CRF was associated with a 3.27 kg/m2 (95% confidence intervals (CI): -3.35; -3.2) and 4.56 kg/m2 (95% CI: -4.67; -4.46) lower BMI in men and women, respectively. Waist circumference was 6.7 cm [95% CI: -6.98; -6.42] and 9 cm [95% CI: -9.33; -8.67] lower per 1-MET increment in CRF. With one MET increment, the probability of being obese was 34% (PR = 0.66 [95%CI: 0.63; 0.69]) and 36% (PR = 0.64 [95%CI: 0.61; 0.67]) lower in men and women, respectively. The probability of having a central obesity was 26% (PR = 0.74 [95%CI: 0.71; 0.77]) and 30% (PR = 0.70 [95%CI: 0.68; 0.73]) lower in men and women, respectively. Conclusions: A higher estimated CRF was associated with lower adiposity levels and a lower risk of being obese in both men and women. Public health policies aiming to increase physical activity are needed to increase the CRF of the Chilean population.

RESUMEN Este trabajo tiene por objetivo defender la incorporación de la perspectiva de género como una estrategia que favorece el logro de la tutela judicial efectiva para mujeres y personas LGBTIQ+. Afirmamos que el acceso a la justicia debe ser comprendido como un derecho humano indispensable en un Estado democrático, debiendo cuidar la remoción de los obstáculos que afectan especialmente a estas categorías de personas, como lo han indicado estándares internacionales de derechos humanos. En ese contexto, a partir del caso chileno, sostenemos que la perspectiva de género es una herramienta que, llevada al ejercicio de la función jurisdiccional, contribuye a hacer efectiva la tutela judicial.

ABSTRACT This work aims to defend the inclusion of the gender perspective as a tool that favors the legal protection of rights for women and LGBTIQ+ people. We uphold the idea that the access to justice must be understood as an essential human right in a democratic state. So, it is relevant to remove obstacles affecting these categories of people in line with the international human rights standards. In this context, based on the Chilean case, we endorse the idea that, within the jurisdictional function, the gender perspective contributes to a more effective protection of rights.
