Abstract Objective: to analyze the way in which feelings and the recovery of collective memory make it possible to reduce the social and political fragility of the members of the Medical Mission, making new ways of participation feasible, through the development of deliberative capacities from a bioethical perspective. Methodology: exploratory study with qualitative approach, which considers the subjectivity and intersubjectivity of the participants. With heterogeneous sources of information: focus groups, semi-structured interviews and field primers, a framework of relevant factors was constituted, which allowed processing the information, through conceptual relationships and categorizations, for its subsequent triangulation. Results: the feelings with the greatest ethical impact in Mission Medical: uncertainty, insecurity at work, anxiety due to acts of violence, sadness, fear, fear, and impotence; produce emotional effects related to the principle of maleficence. Resilience has prevented them from carrying out collective memory exercises, due to denial and fear of remembering the most significant events, which has prevented them from accessing Restorative Justice mechanisms. The absence of capacities to face the situation compromises individual autonomy, occupational health and generates unresolved legal shortcomings. Conclusions: collective feelings in the public sphere of health personnel prevail over individual feelings based on experiences, which affect the capacity for deliberation, this implies promoting exercises of historical memory on the facts of the conflict, through the development of capacities that strengthen the legitimate defense of their autonomy and the development of a beneficial professional exercise, in the face of borderline situations of confrontation.

Resumen Objetivo: analizar la forma en que los sentimientos y la recuperación de la memoria colectiva, posibilitan la disminución de la fragilidad social y política de los integrantes de la Misión Médica, haciendo factible nuevas maneras de participación, mediante el desarrollo de capacidades deliberativas desde la perspectiva bioética. Metodología: estudio exploratorio con enfoque cualitativo, que toma en cuenta la subjetividad e intersubjetividad de los participantes. Con fuentes de información heterogénea: grupos focales, entrevistas semiestructuradas y cartillas de campo, se constituyó un marco de factores relevantes, que permitieron procesar la información, mediante relaciones y categorizaciones conceptuales, para su posterior triangulación. Resultados: los sentimientos con mayor impacto ético en Misión Médica: incertidumbre, inseguridad ante el trabajo, ansiedad por los hechos de violencia, tristeza, temor, miedo e impotencia; producen efectos emocionales relacionados con el principio de maleficencia. La resiliencia, ha impedido realizar ejercicios de memoria colectiva, a causa del negacionismo y temor a recordar los hechos más significativos, esto les ha impedido el acceso a los mecanismos de Justicia Restaurativa. La ausencia de capacidades para afrontar la situación compromete la autonomía individual, la salud laboral y genera carencias legales no resueltas. Conclusiones: los sentimientos colectivos en el ámbito público del personal sanitario prevalecen sobre los sentimientos individuales basados en vivencias, que afectan la capacidad de deliberación, esto implica promover ejercicios de memoria colectiva, sobre los hechos del conflicto, mediante el desarrollo de capacidades que fortalezcan la legitima defensa de su autonomía y el desarrollo de un ejercicio profesional beneficiente, ante situaciones limítrofes de confrontación.

Resum Objectiu: analitzar la manera com els sentiments i la recuperació de la memòria col·lectiva, possibiliten la disminució de la fragilitat social i política dels integrants de la Missió Mèdica, fent factible noves maneres de participació, mitjançant el desenvolupament de capacitats deliberatives des de la perspectiva bioètica. Metodologia: estudi exploratori amb enfocament qualitatiu, que té en compte la subjectivitat i la intersubjectivitat dels participants. Amb fonts d'informació heterogènia: grups focals, entrevistes semiestructurades i cartilles de camp, es va constituir un marc de factors rellevants, que van permetre processar la informació, mitjançant relacions i categoritzacions conceptuals, per triangular-les posteriorment. Resultats: els sentiments amb més impacte ètic a Missió Mèdica: incertesa, inseguretat davant la feina, ansietat pels fets de violència, tristesa, temor, por i impotència; produeixen efectes emocionals relacionats amb el principi de maleficència. La resiliència, ha impedit fer exercicis de memòria col·lectiva, a causa del negacionisme i temor de recordar els fets més significatius, això els ha impedit l'accés als mecanismes de Justícia Restaurativa. L'absència de capacitats per fer front a la situació compromet l'autonomia individual, la salut laboral i genera mancances legals no resoltes. Conclusions: els sentiments col·lectius en l'àmbit públic del personal sanitari prevalen sobre els sentiments individuals basats en vivències, que afecten la capacitat de deliberació, això implica promoure exercicis de memòria col·lectiva, sobre els fets del conflicte, mitjançant el desenvolupament de capacitats que enforteixin la legítima defensa de la seva autonomia i el desenvolupament d'un exercici professional beneficient, davant de situacions limítrofes de confrontació.

Abstract Sapajus libidinosus members of the Pedra Furada group, living in the Serra da Capivara National Park, use stone tools in a wider variety of behaviors than any other living animal, except humans. To rescue the evolutionary history of the Caatinga S. libidinosus and identify factors that may have contributed to the emergence and maintenance of their tool-use culture, we conducted fieldwork seasons to obtain biological samples of these capuchin monkeys. UsingCYTBsequences, we show a discrete but constant population growth from the beginning of the Holocene to the present, overlapping the emergence of the Caatinga biome. Our habitat suitability reconstruction reports the presence of plants whose hard fruits, seeds, or roots are processed by capuchins using tools. TheS. libidinosusindividuals in the Caatingawere capable of dynamically developing and maintaining their autochthonous culture thanks to: a) cognitive capacity to generate and execute innovation under selective pressure; b) tolerance favoring learning and cultural inheritance; c) an unknown genetic repertoire that underpins the adaptive traits; d) a high degree of terrestriality; e) presence and abundance of natural resources, which makes some places “hot spots” for innovation, and cultural diversification within a relatively short time. group Park animal humans S tooluse tool monkeys UsingCYTBsequences present biome fruits seeds TheS pressure b inheritance c traits d terrestriality e resources hot spots time

Abstract Introduction: The central nervous system as well as the cardiovascular system are target organs, susceptible to endogenous and exogenous injuries. In this sense, the role that obesity has in relation to the direct or indirect affection towards the nervous tissue is little known, however, there is evidence that suggests that the decrease in cerebral blood flow as well as the exaggerated production of pro-inflammatory cytokines could be associated with damage to cellular tissue including gray matter and white matter. Objective: The objective of our study was to review the available scientific literature on the macro and microstructural changes caused by obesity in the nervous system. Methodology: Searches were made in English and Spanish in PubMed, GoogleSchoolar and Scielo using the following search terms: “OBESITY” OR “OVERWEIGHT” AND “BRAIN STRUCTURE” OR “GRAY MATTER” OR “WHITE MATTER” OR “BRAIN VOLUME”. We included articles since 2000 to 2021. Results: The results show that obesity is associated with a decrease in brain tissue volume, possibly at the expense of a decrease in white and gray matter, which also causes demyelination and diffuse axonal damage in patients with body mass index > 30. Conclusions: There are different mechanisms that affect the nervous system, producing macro and microscopic changes in obese patients, among which are decreased blood flow, alteration of the blood-brain barrier, production of proinflammatory cytokines, production of reactive oxygen species, among others, which lead to nerve cell apoptosis, decreased white matter volume white and gray matter volume, axonal damage among others.

Resumen Introducción: El sistema nervioso central, así como también el sistema cardiovascular son órganos blancos susceptibles a injurias endógenas y exógenas. En ese sentido, el rol que tiene la obesidad en relación a la afección directa o indirecta hacia el tejido nervioso es poco conocida, sin embargo, existe evidencia que sugiere que la disminución del flujo sanguíneo cerebral, así como también la producción exagerada de citoquinas proinflamatorias podrían estar asociadas a daños del tejido celular incluida la materia gris y la materia blanca. Objetivos: El objetivo de nuestro estudio fue el de revisar la literatura científica disponible alrededor de los cambios macro y microestructurales ocasionados por la obesidad en el sistema nervioso. Metodología: Se realizo búsquedas en inglés y español en PubMed, GoogleSchoolar y Scielo usando los siguientes términos de búsqueda: “OBESITY” OR “OVERWEIGHT” AND “BRAIN STRUCTURE” OR “GRAY MATTER” OR “WHITE MATTER” OR “BRAIN VOLUME”. Se incluyeron artículos desde el 2000 al 2021. Resultados: Los resultados demuestran que la obesidad se asocia a una disminución del volumen tisular cerebral posiblemente a expensas de una disminución de la materia blanca y gris que además ocasiona desmielinización y daño axonal difuso en pacientes con índice de masa corporal > 30. Conclusiones: Existen diferentes mecanismos que afectan al sistema nervioso produciendo cambios macro y microscópicos en pacientes obesos entre los cuales se encuentran la disminución del flujo sanguíneo, alteración de la barrera hematoencefálica, producción de citoquinas proinflamatorias, producción de especies reactivas de oxígeno entre otras los cuales conducen a apoptosis de células nerviosas, disminución del volumen de la materia blanca volumen de la materia blanca y gris, daño axonal entre otros.

ABSTRACT Background: Leishmaniasis is a vector-borne disease caused by a parasite protozoon from the genus Leishmania. Among the molecular techniques applied for detecting these parasites, real-time PCR with High Resolution Melting (PCR-HRM) proved advantageous since it simultaneously determines both the presence and species of the pathogen in one step, through amplification and later analysis of curves generated by melting temperature. Methods: Based on this molecular technique, the goal of this study was to estimate the PCR-HRM sensitivity for Leishmania spp. detection in different canine tissues by evaluating biological samples obtained from popliteal, submandibular, and pre-scapular lymph nodes, from bone marrow and ear pinnae of 28 stray dogs captured in the metropolitan area of Asunción (Paraguay). Results: The rk39 immunochromatographic test showed that 25/28 tested dogs (89%) presented antibodies against L. infantum. In 20/25 dogs that tested positive for rk39 (80%), it was possible to detect Leishmania spp. by PCR-HRM and determine that the species corresponded entirely to L. infantum. Regarding the analysis of different tissues, the parasite was detected in all popliteal lymph node samples, followed by high detection in submandibular (at 95%) and pre-scapular lymph nodes (at 90%), bone marrow (at 85%), and ear pinnae (at 85%). Conclusions: This study demonstrated that the use of real-time PCR-HRM using the molecular marker hsp70 was a highly sensitive method for simultaneously detecting and identifying Leishmania species in different tissues taken from infected dogs. In addition, the usefulness of ear pinnae as easily accessible tissue for molecular diagnosis was emphasized.

RESUMEN Introducción: La lactancia materna (LM) es un factor protector contra la obesidad infantil; sin embargo, los mecanismos a través de los cuales ejerce este efecto aún no están claros. El objetivo fue describir los mecanismos asociados al efecto protector que ejerce la lactancia materna contra la obesidad infantil. Métodos: Se utilizaron los buscadores PUBMED, SCOPUS, Cochrane Library y Scielo para desarrollar una revisión descriptiva de la evidencia científica. Las palabras clave fueron: lactancia materna, obesidad, mecanismo y dieta. Se revisaron artículos en español e inglés, desde 1977 hasta el 2020. Resultados: El efecto protector de la LM contra la obesidad infantil está dado por una combinación de varios mecanismos, se destaca su composición nutricional y el aporte de sustancias bioactivas, algunas de ellas reguladoras de la ingesta energética. Los lactantes que reciben LM por más tiempo seleccionan alimentos más saludables en etapa preescolar, independiente de factores sociodemográficos. También han sido descritos efectos en la adiposidad, el control del peso corporal y la ingesta energética mediante regulación de la programación epigenética y de la microbiota intestinal. Conclusión: La LM es un proceso único, que interacciona de forma compleja con factores del crecimiento y desarrollo de los lactantes y preescolares. Su rol protector contra la obesidad ha sido asociado a diversos mecanismos. Sin embargo, se requiere de nuevas investigaciones para comprender los alcances que puede presentar la LM en la etapa pediátrica y su rol en la prevención de la obesidad.

ABSTRACT Background and aim: Breastfeeding (BF) is a protective factor against childhood obesity; however, the mechanisms associated with this effect have not yet been elucidated. This study aimed to describe the mechanisms related to the protective effect of breastfeeding against childhood obesity. Methods: A search on PUBMED, SCOPUS, Cochrane Library and SCIELO databases was carried out to develop a descriptive review of the scientific evidence. The key words were breastfeeding; obesity; mechanism and diet. Articles were reviewed in Spanish and English from 1977 to 2020. Results: The protective effect of BF against childhood obesity is given by a combination of several mechanism. Its nutritional composition and the contribution of bioactive substances stand out, some of them regulated by the energy intake. Infants who are breastfed choose healthier foods in preschool, regardless of sociodemographic factors. Effects on adiposity, control of body weight and energy intake have also been described by epigenetic regulation programming and the intestinal microbiota. Conclusion: BF is a unique process that interacts in a complex way with infants and preschoolers’ growth and developmental factors Its protective role against childhood obesity has been associated with various mechanisms. New research is still required to understand the implications of BF in pediatric age and its role in preventing obesity.

Resumen El suicidio ha aumentado en cerca de un 60% en los últimos cuarenta años. En Colombia, para el año 2019, el 10.9% de las muertes violentas se presentaron por suicidio. Este estudio busca identificar los factores de riesgo asociados con los intentos repetidos de suicidio y además realiza un análisis descriptivo del manejo dado a estos pacientes. Esta investigación utiliza la base de datos de la unidad de emergencias en un hospital del norte de Colombia, y se centra en los pacientes que acudieron al hospital por intento de suicidio entre enero de 2008 y junio de 2019. La base de datos presenta 336 casos de los cuales el 81% corresponden a intentos suicidas y 19% a gestos. Resultados de un análisis de regresión logística multivariada mostraron que la ideación suicida y la historia de desorden psiquiátrico predecían significativamente los intentos suicidas repetidos y que los intentos repetidos eran más probables en el grupo de individuos menores de edad y en adultez temprana. El tratamiento administrado a los pacientes fue hospitalización y servicios ambulatorios; un porcentaje fue enviado a casa con recomendaciones. Los hallazgos de este estudio destacan la importancia del desarrollo de protocolos estandarizados basados en evidencia para prevenir los intentos repetidos.

Abstract Suicide has increased close to 60% in the last four decades worldwide. In Colombia, during the year 2019, 10,9% of violent deaths were due to suicide. This study aimed to identify risk factors predicting repeated suicide attempts. It also aimed to describe the management of suicidal behaviour within an emergency department of Northern Colombia. Dataset comprised 336 medical records of individuals seeking medical assistance for intentional self-harm between 2008-2019; 136 medical records were associated with previously reported suicide attempts. Results from a multivariate logistic regression showed that suicide ideation and having a history of psychiatric disorders significantly predicted repeated suicide attempts. Furthermore, repeated attempts were more likely in underaged individuals and young adults. Management of patients engaging in suicidal behaviour involved hospitalization and outpatient mental health services. However, a few patients were sent home with recommendations or were non-compliant. Findings from this study highlight the importance to develop evidence-based screening and monitoring protocols that prevent repeated suicide attempts.

Abstract Introduction The average life expectancy, as well as the prevalence of Type 2 diabetes (T2D), is increasing worldwide. Population-based studies have demonstrated that the duration of T2D has been associated with cognitive impairment. However, despite the high prevalence of T2D and cognitive impairment in Chile, the association between years with T2D and suspicion of cognitive impairment has not yet been investigated. The objective of this study was to investigate the association between duration of T2D and suspicion of cognitive impairment in Chilean older adults. Material and Methods 1,040 older adults aged ≥60 years from the Chilean National Health Survey (2009-2010) were included. Suspicion of cognitive impairment was assessed by the abbreviated Mini-Mental State Examination (MMSE). The number of years with T2D was self-reported and categorised into four groups. Poisson Regression analysis was used to assess the association between altered MMSE and the number of years with DM2, adjusted by potential confounders including socio-demographic, lifestyle, adiposity and health-related factors. Results When the analyses were adjusted for socio-demographic factors, people who had T2D for 15 to 24 and ≥25 years had 2.2-times (95%CI: 1.07; 3.33) and 5.8-times (95%CI: 3.81; 11.0) higher relative risk (RR) of cognitive impairment, compared to those without T2D. When the analyses were additionally adjusted for lifestyle and health-related covariates, the RR for cognitive impairment was 1.76-times (95%CI: 1.02; 2.50) and 4.54-times (95%CI: 2.70; 6.38) higher for those who had T2D for 14-24 years and ≥25 years, respectively. Conclusions Number of years with T2D was associated with suspicion of cognitive impairment. A longer duration of T2D was associated with a higher likelihood of cognitive impairment in the Chilean older population, independently of confounder factors included in the study.

RESUMEN Introducción: La esperanza de vida está aumentando en todo el mundo, así como la diabetes tipo 2 (DM2). Estudios poblacionales han demostrado que la duración de la DM2 se ha asociado con el deterioro cognitivo. Sin embargo, a pesar de la alta prevalencia de DM2 y deterioro cognitivo en Chile, aún no se ha investigado la asociación entre años con DM2 y la sospecha de deterioro cognitivo. El objetivo del estudio fue investigar la asociación entre la duración de la DM2 y la sospecha de deterioro cognitivo en personas mayores chilenas. Material y Métodos Participaron 1.040 personas ≥60 años de la Encuesta Nacional de Salud de Chile (2009-2010). El deterioro cognitivo se evaluó mediante el Mini Examen del Estado Mental abreviado (MMSE). El número de años con DM2 fue categorizado en cuatro grupos. Para valorar la asociación entre MMSE alterado y el número de años con DM2, se utilizó una regresión de Poisson, ajustados a posibles factores de confusión sociodemograficos, de estilos de vida, adiposidad y salud. Resultados Cuando se ajustaron los análisis por factores sociodemográficos, las personas con 15 a 24 y ≥25 años con DM2 presentaron 2,2 veces (IC95%: 1,07; 3,33) y 5,8 veces (IC95%: 3,81; 11,0) riesgo relativo (RR) de deterioro cognitivo, en comparación con aquellas sin DM2. Luego de ajustar adicionalmente los análisis para las covariables relacionadas con el estilo de vida y la salud, el RR para deterioro cognitivo fue 1,76 veces (IC95%: 1,02; 2,50) y 4,54 veces (IC95%: 2,70; 6,38) más alto para aquellas personas con 14-24 y ≥25 años de DM2. Conclusiones Se asoció el número de años con DM2 con la sospecha de deterioro cognitivo. Una mayor duración de la DM2 se asoció con una mayor probabilidad de deterioro cognitivo en la población mayor chilena.

ABSTRACT Background: Falls among older adults are associated with important changes in lifestyle. However, there is no evidence about the physical activity levels of older adults who have experienced falls. The aim of this study, therefore, was to describe physical activity levels in older adults who have experienced falls in the last 12 months. Methods: 1,254 older adults (aged ≥60 years) from the National Health Survey 2009-2010 were included in this study. Number of falls during the last 12 months was self-reported and physical activity was measured using the Global Physical Activity Questionnaire (GPAQ). The association between falls and physical activity was investigated using regression analyses. Results: 70.5% [95% CI: 68.0; 72.8] of the older adults included in this study did not report any falls during the last 12 months. However, 19.4% [95% CI: 17.4; 21.5] reported 1-2 falls and 10% [95% CI: 8.4; 11.8] reported ≥3 falls in the last 12 months. In comparison to those who reported no falls, those who experienced ≥3 falls in the last 12 months did 79.2 fewer minutes/day of physical activity. Similar results were found for moderate and transport-related physical activity, but no associations were found for vigorous or sedentary behaviours. Conclusion: Older adults who suffered falls in the last 12 months reported doing less physical activity than their counterparts who did not experience any falls. In the middle and long term, these changes in physical activity could contribute to adverse health outcomes in an already frail population.

RESUMEN Antecedentes: Las caídas limitan las actividades de la vida diaria. Actualmente se desconoce cómo los niveles de actividad física (AF) varían luego de sufrir una caída. Objetivo: investigar los niveles de práctica de actividad física de personas mayores que han reportado caídas en los últimos 12 meses. Métodos: Se incluyeron 1.254 participantes ≥ 60 años de Encuesta Nacional de Salud (ENS) 2009-2010. La prevalencia de caídas en los últimos 12 meses se determinó mediante auto reporte. Los niveles de AF y el tiempo sedente se determinaron a través del cuestionario Global Physical Activity Questionnaire (GPAQ). La asociación entre caídas y AF fue investigada mediante regresión lineal. Resultados: El 70,5% [95% IC: 68,0; 72,8] de las personas mayores no reportaron caídas, mientras que un 19,4% [95% IC: 17,4; 21,5] reportó haber sufrido entre 1-2 caídas y un 10% [95% IC: 8,4; 11,8] ≥3 caídas en los últimos 12 meses. En comparación al grupo que reportó no sufrir caídas, aquellos que sufrieron ≥3 caídas realizaban 79,2 minutos menos de AF total/día. Resultados similares fueron observados para AF de transporte y AF moderada. No se encontraron diferencias para tiempo sedente o AF vigorosa. Conclusión: Personas mayores que sufrieron caídas en los últimos 12 meses reportaron realizar menos actividad física que sus contrapartes que no experimentaron caídas. A mediano y largo plazo, estos cambios en la actividad física podrían contribuir a resultados de salud adversos en una población.

ABSTRACT Objectiv:e to analyze the relationship of anxiety and depression in the preoperative period with the presence of pain in the postoperative period. Method: cohort study conducted at a university hospital in the state of Minas Gerais (Brazil), between february and July 2017, with 65 patients. A collection instrument was elaborated for the demographic and clinical characteristics. The Hospital Anxiety and Depression Scale was used to assess anxiety and depression; pain intensity was measured using the Verbal Numerical Scale. Data were submitted to descriptive and inferential statistical analysis. Results: according to demographic and clinical characteristics, most patients were female, with a median age of 44 years and surgical specialty of the digestive tract. In the preoperative period, 31 (47.7%) had anxiety, and nine (13.8%), depression. None of the patients reported pain immediately prior to surgery. The incidence of moderate to severe postoperative pain was 32 (49.2%) patients. There was a statistically significant difference in the distribution of patients with postoperative pain in relation to the presence or absence of preoperative anxiety (p value <0.001). There is no statistically significant difference in the distribution of patients with postoperative pain in relation to the presence or absence of preoperative depression (0.733). In multivariate analysis, preoperative anxiety was a predictive factor for postoperative pain. Depression was not a predictive factor of postoperative pain. Conclusion: It was demonstrated that, regardless of the demographic and clinical characteristics of the studied sample, the presence of anxiety in patients in the preoperative period is a predictive factor of postoperative pain.

Conclusão: foi demonstrado que, independentemente das características demográficas e clínicas da amostra estudada, a presença da ansiedade nos pacientes no período pré-operatório é um fator preditivo da dor no período pós-operatório.

Cancer is a chronic non-communicable disease associated with a high mortality burden. The prevalence of cancer is increasing rapidly worldwide. However, this scenario will be worse in low and middle-income countries such as Chile, where 70% of cancer deaths occur. The aim of this review was to assess the epidemiological scenario of cancer and its projection for the Chilean population. In Chile, 53,365 new cases of cancer were diagnosed in 2018, led by prostate, colorectal, breast, stomach, lung and gallbladder cancer. From 1986 to 2016, cancer increased by 109%. When we reviewed mortality by sex, stomach and prostate cancer were responsible for more than 30% of cancer deaths among men. However, for women the first three places were occupied by breast, colorectal and lung cancer, as in the rest of the world. Considering that 40% of cancers are related to unhealthy lifestyles, working on the prevention of modifiable risk factors represents an opportunity for the creation of public health policies that allow changes at the environmental and individual level.

ABSTRACT Introduction: Determining level of physical activitY (PA) can be done with objective measurement, through accelerometer, or by subjective measurement through self-report questionnaire. The aim of this study was to compare PA measurements derived from a self-reported questionnaire and accelerometer according to sociodemographic factors in the Chilean population. Methods: This was a cross-sectional study which included 230 Chilean adults participating in the GENADIO study (Genes, Environment, Diabetes and Obesity). PA levels were measured through the International Physical Activity Questionnaire (IPAQ) and GT1M accelerometer (ActiTrainer, ActiGraph). Results: IPAQ questionnaire underestimated the total PA levels compared to the accelerometer measurement (delta[IPAQ-Acel.]= −55.7 min/day). According to educational level, IPAQ questionnaire overestimated PA level in people with low educational level (delta[IPAQ-Accel.]= 70.4 min/day), but underestimated total PA in people with secondary education or university technician (delta[IPAQ-Accel.]=-67.9 and-135.6 min/day, respectively). Similar results were observed for the different levels of socioeconomic income. Conclusion: The IPAQ questionnaire underestimated total PA levels compared to accelerometer; however, these differences varied according to sociodemographic factors.

RESUMEN Introducción: La determinación del nivel de actividad física (AF) puede realizarse a través de acelerómetro o mediante cuestionario de auto-reporte. El objetivo de este estudio fue comparar los niveles de AF entre un cuestionario de auto-reporte y la medición con acelerómetro de movimiento según factores sociodemográficos en la población chilena. Métodos: Estudio de corte transversal que incluyó a 230 adultos chilenos participantes del proyecto Genes, Ambiente, Diabetes y Obesidad (GENADIO). Niveles de AF fueron medidos mediante el cuestionario Internacional Physical Activity Questionnaire (IPAQ) y acelerómetro de movimiento (ActiGraph). Resultados: IPAQ subestimó los niveles de AF total en comparación a la medición con acelerómetro (delta [IPAQ-Acel.]= −55,7 min/día). Según nivel educacional, se evidenció que el cuestionario IPAQ sobreestimó los niveles de AF total en personas con bajo nivel educacional (delta [IPAQ-Acel.]= 70,4 min/día), pero subestimó la AF total en personas con enseñanza media o técnico universitaria (delta [IPAQ-Acel.]= −67,9 y −135,6 min/día, respectivamente). Resultados similares fueron observados para los distintos niveles de ingreso socioeconómico (NSE). Conclusión: El cuestionario de auto-reporte IPAQ subestimó los niveles de AF total en comparación a la medición por acelerómetro; sin embargo, estas diferencias variaron según factores sociodemográficos.

SARS-CoV-2 is a new virus responsible for the outbreak of the respiratory disease COVID-19, which has spread to several countries around the world, causing considerable consternation and a fear of contagions in global healthcare settings. The objective of this study is to identify, among Madrid’s adult population, the impact of COVID-19 on self-perceived vulnerability, infectiousness, aversion to germs, and other behaviors in the current situation regarding dental practice. This cross-sectional observational study involves 1,008 persons randomly surveyed on the streets of Madrid, Spain between March 1 and March 8, 2020. Their perceived vulnerability to disease was measured using the perceived vulnerability to disease scale. An additional questionnaire evaluated basic sociodemographic aspects, medical history, personal hygiene behavior, willingness to go to certain places and the perception of the risk of contagion when going to a dental practice. There are significant differences by sex on the germ aversion subscale (p &lt; 0.05) and in the risk of waiting in the waiting room (p &lt; 0.01), tooth extraction ((p &lt; 0.05), endodontics (p &lt; 0.05) and fillings ((p &lt; 0.05). Women consider the risk to be higher than men do. The risk group (over 60 and with systemic disease) has significant differences on the subscales of infectivity (p &lt; 0.01) and germ aversion (p &lt; 0.01). Our study shows high levels of vulnerability regarding contracting COVID-19 and avoiding dental care as perceived by the population over 60 years old and with a systemic disease.

Abstract Objectives To compare health-related quality of life (QoL) of medical students in initial and final phases of the program, and to evaluate the association between ego defense mechanisms and specific health-related QoL domains within each group. Methods This was an observational, cross-sectional study. Quality of life was assessed according to the World Health Organization Quality of Life instrument - Abbreviated Version (WHOQOL-Bref); anxiety and depression symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS); defense mechanisms were assessed using the Defense Style Questionnaire (DSQ-40) Results A total of 139 medical students were evaluated. Students in the initial semesters of the program (1st and 3rd) presented more depressive symptoms and worse quality of life in the psychological domain of WHOQOL-Bref when compared to those in the final semesters (8th and 12th). In a later analysis, conducted to identify the variables associated with the psychological domain of the WHOQOL-Bref for each group, both depressive symptoms and defense mechanisms were independently associated with the outcome for medical students in the beginning and in the end of the graduation program. Conclusions Students in the initial phases of medical school may need more specific attention from educational managers. Understanding the role of ego defense mechanisms in the quality of life of medical students may help identify effective psychopedagogical interventions for this population. In addition, the results reinforce the impact of depressive symptoms on quality of life, an association already well evidenced in the literature.

We evaluated sweat, blood and urine specimens obtained from an ongoing cohort study in Brazil. Samples were collected at pre-established intervals after the initial rash presentation and tested for Zika virus (ZIKV) RNA presence by real-time reverse transcriptase polymerase chain reaction (rRT-PCR). From 254 participants with confirmed infection, ZIKV RNA was detected in the sweat of 46 individuals (18.1%). Sweat presented a median cycle threshold (Ct) of 34.74 [interquartile range (IQR) 33.44-36.04], comparable to plasma (Ct 35.96 - IQR 33.29-36.69) and higher than urine (Ct 30.78 - IQR 28.72-33.22). Concomitant detection with other specimens was observed in 33 (72%) of 46 participants who had a positive result in sweat. These findings represent an unusual and not yet investigated virus shedding through eccrine glands.

Objetivo: avaliar as propriedades psicométricas da Escala de Confiança no Autocuidado na insuficiência cardíaca da versão brasileira do Self-Care Heart Failure Index, versão 6.2, usando os critérios do modelo Rasch. Método: estudo secundário, de análise psicométrica, pelo modelo de Rasch, dos seis itens da escala. A amostra foi constituída por 409 pacientes com insuficiência cardíaca em tratamento ambulatorial [idade média de 57,9 (desvio-padrão=11,6) anos, 54,8% do sexo masculino]. Resultados: do total de seis itens, um (“De maneira geral, você está confiante sobre estar livre dos sintomas de insuficiência cardíaca?”) apresentou desajuste ao modelo (Infit=1,84 e Outfit=1,99). Após a exclusão desse item, os demais apresentaram bom ajuste, compuseram uma dimensão e explicaram 55% da variância nos dados; as categorias de resposta aos itens foram adequadas, os valores de separação e confiabilidade das pessoas foram 2,13 e 0,82, respectivamente, e o alfa de Cronbach foi 0,87. Foram identificados os itens de extremos de dificuldade e que não há funcionamento diferencial dos itens em relação a sexo. Conclusão: com a exclusão do primeiro item, a Escala de Confiança no Autocuidado apresentou boas propriedades psicométricas, recomendando-se cautela na interpretação dos resultados da escala com seis itens.

Objective: to evaluate the psychometric properties of the Self-Care Confidence Scale in heart failure in the Brazilian version of the Self Care Heart Failure Index, version 6.2, using the Rasch model criteria. Method: secondary study, of psychometric analysis, using the Rasch model, of the six items of the scale. The sample consisted of 409 patients with heart failure undergoing outpatient treatment [mean age 57.9 (standard deviation = 11.6) years, 54.8% male]. Results: of the total of six items, one (“De maneira geral, você está confiante sobre estar livre dos sintomas de insuficiência cardíaca?”) presented maladjustment to the model (Infit = 1.84 and Outfit = 1.99). After the exclusion of this item, the others showed a good fit, composed one dimension and explained 55% of the variance in the data; the categories of response to the items were adequate, the values of separation and reliability of person were 2.13 and 0.82, respectively, and Cronbach’s alpha was 0.87. Items of extreme difficulty were identified and there is no differential functioning of the items in relation to sex. Conclusion: with the exclusion of the first item, the Self-Care Confidence Scale showed good psychometric properties, with caution in interpreting the results of the six-item scale.
