Adaptación cultural y análisis psicométrico de una escala de comportamientos de autocuidado en personas con insuficiencia cardíaca / Cultural adaptation and psychometric analysis of a scale of self-care behaviors in persons with heart failure

INTRODUCCIÓN: La Insuficiencia Cardiaca se ha descrito como un síndrome de proporciones epidémicas, con una prevalencia de un 1-3% de la población adulta mundial menor de 60 años. Las conductas de autocuidado constituyen una estrategia clave en la elaboración de intervenciones exitosas que disminuyan la re-hospitalización, mortalidad y mejoren la calidad de vida. OBJETIVO: Adaptar y validar la Escala Revisada de Comportamientos de Autocuidado en Falla Cardiaca (Revised Heart Failure Self Care Behavior Scale) en personas con insuficiencia cardíaca, que se encuentran en seguimiento ambulatorio, en dos Hospitales Públicos chilenos. METODOLOGÍA: Estudio transversal de adaptación y análisis psicométrico del instrumento de medición Escala de Valoración de Comportamientos de Autocuidado en personas con Insuficiencia Cardíaca diseñada por Nancy Artinian. Emplazamiento: Unidades ambulatorias de seguimiento en Hospitales Públicos chilenos. Participantes: Usuarios con Insuficiencia Cardíaca que asistieron a dos Policlínicos de seguimiento de Insuficiencia Cardiaca de dos Centros de Salud de nivel secundario de dos comunas de Santiago en Chile. Método: Se realizó juicio de expertos para la adaptación cultural del instrumento, se aplicó el análisis factorial exploratorio con rotación oblicua. RESULTADOS: Escala Chilena de Valoración Comportamientos de Automanejo en Insuficiencia Cardiaca presentó una adecuada adaptación cultural, pruebas sicométricas que garantizan su validez de constructo y fiabilidad adecuada, con Alfa de Cronbach del Instrumento de 0,84 IC [0,80-0,88]. CONCLUSIONES: Se proporciona un instrumento que permite conocer conductas de autocuidado de los pacientes con IC, esto le permite ser utilizado por los profesionales que atienden a personas que padecen de IC en Chile.

INTRODUCTION: Heart failure (HF) has been described as a syndrome of epidemic proportions, with a prevalence of 1-3% amongst the global adult population under 60 years of age. Self-care behaviors are a key strategy in the development of successful interventions that reduce re-hospitalization, mortality and improve quality of life. OBJECTIVE: To adapt and validate the Revised Heart Failure Self-Care Behavior Scale in people with heart failure, who are in outpatient follow-up, in two Chilean public hospitals. DESIGN: Cross-sectional study of adaptation and psychometric analysis of the measuring instrument Scale of Assessment of Self-Care Behavior in Persons with Heart Failure, designed by Nancy Artinian. Location: Outpatient follow-up units in Chilean public hospitals. Participants: Patients with Heart Failure who attended two heart failure outpatient follow-up clinics within two secondary healthcare centers located in two districts of Santiago, Chile. Method: Expert judgments were made for the cultural adaptation of the instrument, followed by exploratory factor analysis with oblique rotation. RESULTS: The Chilean Scale of Assessment of Self-Management Behaviors in Heart Failure presented adequate cultural adaptation, psychometric tests that guarantee its validity in terms of its construction and adequate reliability. Cronbach's Alpha of the Instrument was 0,84 IC [0,80-0,88] CONCLUSIONS: The study provides a tool that allows us to ascertain the self-care behaviors of patients with HF, allowing it to be used by professionals who care for people with HF in Chile.

Discriminación racial y Determinantes Sociales de la salud en niños y niñas migrantes: revisión narrativa

Objetivo: Analizar la relación entre Determinantes Sociales de la Salud (DSS) y discriminación en niños, niñas y adolescentes migrantes a partir de la información disponible en la literatura científica. Método: Revisión narrativa de estudios primarios publicados entre 2008 y 2021 en las bases de datos PubMed y Web of Science. Se utilizaron los descriptores "Psychological/Social Discrimination", "Racism", "Social Stigma", "Social Determinants of Health", "Public Health", "Health Equity", "Transients and Migrants", "Refugees", "Emigrants and Immigrants", "Undocumented Immigrants", "Child", "Adolescent", "Child, "Preschool". Los operadores booleanos utilizados fueron AND y OR. Se incluyeron artículos observacionales (analíticos o descriptivos) que evaluaran la relación entre discriminación racial y DSS, publicados en inglés o español. La población de estudio fueron niños, niñas y adolescentes. La selección de artículos se realizó siguiendo las recomendaciones PRISMA. La calidad de la evidencia fue evaluada mediante la herramienta MMAT. Resultados: De un total de 1249 artículos identificados, se incluyeron 55. La mayor cantidad de artículos identificó el efecto de la relación entre discriminación racial y migración en ámbitos de salud mental negativa. Fue escasa la evidencia respecto de determinantes estructurales, sin embargo, destaca la relación entre discriminación racial y el efecto moderador de la familia y la escuela. Conclusiones: Analizar la discriminación racial que perciben niños y niñas migrantes mediante un enfoque de DSS permite identificar áreas sensibles al desarrollo estrategias de reducción de inequidades en este grupo.

Objective: To analyze the relationship between Social Determinants of Health (SDH) and racial discrimination in migrant children and adolescents, based on the information available in the scientific literature. Method: Narrative review of primary studies published between 2008 and 2021 in PubMed and Web of Science databases. The descriptors "Psychological/Social Discrimination", "Racism", "Social Stigma", "Social Determinants of Health", "Public Health", "Health Equity", "Transients and Migrants", "Refugees", "Emigrants and Immigrants", "Undocumented Immigrants", "Child", "Adolescent", "Child", "Preschool" were using. The Boolean operators used were AND OR. We included observational articles (analytical or descriptive) that evaluated the relationship between racial discrimination and SDH, published in English or Spanish. The study population was children and adolescents. We select articles following the PRISMA recommendations. The evaluation of the quality of the evidence was made using MMAT. Results: Of a total of 1249 articles identified, 55 articles were included. The most significant number of articles identified the relationship between racial discrimination and migration on adverse mental health outcomes. Evidence regarding structural determinants was scarce; however, the relationship between racial discrimination and the moderating effect of family and school stands out. Conclusions: Analyzing racial discrimination as perceived by migrant children through a DSS approach allows us to identify sensitive areas to develop strategies to reduce inequities in this group.

Pathological Findings Associated With SARS-CoV-2 on Postmortem Core Biopsies: Correlation With Clinical Presentation and Disease Course.

Background: Autopsies can shed light on the pathogenesis of new and emerging diseases. Aim: To describe needle core necropsy findings of the lung, heart, and liver in decedents with COVID-19. Material: Cross-sectional study of needle core necropsies in patients who died with virologically confirmed COVID-19. Histopathological analyses were performed, and clinical data and patient course evaluated. Results: Chest core necropsies were performed in 71 decedents with a median age of 81 years (range 52-97); 47 (65.3%) were men. The median interval from symptoms onset to death was 17.5 days (range 1-84). Samples of lung (n = 62, 87.3%), heart (n = 48, 67.6%) and liver (n = 39, 54.9%) were obtained. Fifty-one lung samples (82.3%) were abnormal: 19 (30.6%) showed proliferative diffuse alveolar damage (DAD), 12 (19.4%) presented exudative DAD, and 10 (16.1%) exhibited proliferative plus exudative DAD. Of the 46 lung samples tested for SARS-CoV-19 by RT-PCR, 39 (84.8%) were positive. DAD was associated with premortem values of lactate dehydrogenase of 400 U/L or higher [adjusted odds ratio (AOR) 21.73; 95% confidence interval (CI) 3.22-146] and treatment with tocilizumab (AOR 6.91; 95% CI 1.14-41.7). Proliferative DAD was associated with an onset-to-death interval of over 15 days (AOR 7.85, 95% CI 1.29-47.80). Twenty-three of the 48 (47.9%) heart samples were abnormal: all showed fiber hypertrophy, while 9 (18.8%) presented fibrosis. Of the liver samples, 29/39 (74.4%) were abnormal, due to steatosis (n = 12, 30.8%), cholestasis (n = 6, 15.4%) and lobular central necrosis (n = 5, 12.8%). Conclusion: Proliferative DAD was the main finding on lung core needle necropsy in people who died from COVID-19; this finding was related to a longer disease course. Changes in the liver and heart were common.
