Item Determinación del tiempo T1 y T2 nativo miocárdico en adultos sanos mediante resonancia magnética cardíaca de 1.5 TESLA en resonador GE SIGNA ARTIST de Clínica Alemana, durante el año 2022(2022) Carretero, Sofía; Jara, Catalina; Müller, Constanza; Rodríguez, IgnacioIntroducción: El mapeo T1 y T2 permite cuantificar los valores de los tiempos de relajación T1 y T2 del miocardio. Objetivo: Determinar el tiempo T1 MOLLI, T1 SASHA y T2 nativo del tejido miocárdico en adultos voluntarios sanos en Resonancia Magnética Cardiaca de 1.5 Tesla y, posteriormente, compararlo con los valores de la literatura médica actualizada. Metodología: Desarrollado en Clínica Alemana de Santiago, sede Vitacura. Se realizaron Resonancias Magnéticas Cardíacas en el resonador GE SIGNA Artist de 1.5T, a 63 voluntarios adultos sanos (media edad ± desviación estándar; 38 ± 14; 41 mujeres; 22 hombres) en un intervalo de 3 meses. Los tiempos T1 y T2 nativos del miocardio fueron analizados mediante el software Cvi42. La distribución normal de los datos fue evaluada usando la prueba Kolmogorov - Smirnov, y para la comparación con la literatura, se calculó la media de dichos valores. Resultado: Todos los datos presentan distribución normal. La media de los tiempos de relajación por secuencias MOLLI, SASHA y T2, fue de 1042 ± 43, 1181 ± 75 y 55 ± 3, respectivamente. Conclusión: Esta investigación permitió la determinación de los rangos de normalidad del tejido miocárdico en adultos sanos, valores que aportarán como herramienta complementaria a todas las técnicas utilizadas en RMC hasta el momento.Item Fracture of the anterior tibial tuberosity in children(2020-05) Rodríguez, Ignacio; Sepúlveda, Matías; Birrer, Estefanía; Tuca, MaríaFractures of the anterior tibial tuberosity during childhood are an infrequent pathology (around 3% of all proximal tibial fractures), but the incidence of this injury has risen over recent years, likely due to the increased involvement of this age group in sports activities. This fracture is more commonly seen in children 12–14 years old. It is vital to identify the anatomical structures associated with this type of fracture, along with the pathophysiological mechanisms involved. Treatment includes non-operative and operative options, with the goal of achieving articular congruency, restoring the extensor mechanism function, and avoiding damage to the proximal tibial physis. Understanding the management of this fracture, and the complications that might arise, is critical. The provision of an appropriate clinical management plan and the avoidance of complications are vital in the prevention of disability.Item Infectious and non‑infectious diseases burden among Haitian immigrants in Chile: a cross‑sectional study(2020) Fuster, Francisco; Peirano, Felipe; Vargas, José Ignacio; Zamora, Francisco Xavier; López‑Lastra, Marcelo; Núñez, Ruth; Soza, Jacinta; González, Katherine; Estay, Denisse; Barchiesi, Beatrice; Fuster, Antonieta; López, Ignacia; Utrera, Nicolás; Landeros, Jorge; Chandía, Javiera; Paredes, Angela; Reyes, Daniela; Arias, Rodrigo; Padilla, Luis; Suárez, Hernán; Farcas, Katia; Cannistra, Macarena; Muñoz, Geraldine; Rodríguez, Ignacio; Ormazábal, Ivana; Cortés, Josefina; Cornejo, Bárbara; Manzur, Franco; Reyes, Antonia; Leiva, Vicente; Raimann, María Victoria; Arrau, Catalina; Cox, Valentina; Soza, AlejandroChile has become a popular destination for migrants from South America and the Caribbean (lowand middle-income countries migration). Close to 200.000 Haitian migrants have arrived in Chile. Infectious and non-infectious disease burden among the Haitian adult population living in Chile is unknown. This study aimed to acquire the basic health information (selected transmissible and nontransmissible conditions) of the Haitian adult population living in Chile. A cross-sectional survey was performed, inviting Haitian-born residents in Chile older than 18 years old. Common conditions and risk factors for disease were assessed, as well as selected transmissible conditions (HIV, HBV, and HCV). 498 participants (60.4% female) from 10 communities in two regions of Chile were surveyed. Most subjects had never smoked (91.5%), and 80% drank less than one alcohol unit per month. The mean BMI was 25.6, with 45% of participants having a normal BMI (20–25). Hypertension was present in 31.5% (33% in the 25–44 age group). Prevalence of HIV was 2.4% (95 CI 1.3–4.2%), hepatitis B (HBsAg positive) was 3.4% (95 CI 2.1–5.5%), and hepatitis C was 0% (95 CI 0.0–0.9%). Quality of life showed a significant prevalence of depression and anxiety markers, particularly in those arriving in Chile less than 1 year ago. Low prevalence of obesity, diabetes, smoking, and drinking and estimated cardiovascular risk were found. Nonetheless, hypertension at a younger age, disproportionately higher prevalence of HIV and HBV infection and frequent markers of anxiety and depression were also found. Public policies for detecting and treating hypertension, HIV, and HBV screening, offering HBV vaccination, and organizing mental health programs for Haitian immigrants, are urgently needed.
