RESUMO
La prevalencia de personas con demencias ha aumentado progresivamente y actualmente constituye un desafío en salud pública. Además de fortalecer las herramientas necesarias para su diagnóstico y tratamiento, es necesario desarrollar estrategias que promuevan el respeto de quienes la padecen y mejorar su participación social. El deterioro cognitivo interfiere progresivamente en la toma de decisiones, especialmente en la etapa final de la enfermedad, generando conflictos en torno al respeto por la autonomía y la atención clínica. Las Voluntades Anticipadas y la Planificación Anticipada de Cuidados ofrece la oportunidad de reflexionar sobre valores, deseos y preferencias de atención a futuro, así como la posibilidad de comunicarlos a familiares y equipos de atención, promoviendo el respeto por la autonomía y disminuyendo los conflictos asociados a la atención, especialmente en la etapa terminal. En Chile se ha avanzado progresivamente, pero aun es un desafío implementar las estrategias para consolidar este proceso, superando las barreras existentes y potenciando sus beneficios.
The prevalence of people with dementia has progressively increased and currently constitutes a public health challenge. In addition, to strengthening the necessary tools for diagnosis and treatment, it is essential to develop strategies that promote respect for those who suffer from it and improve their social participation. Cognitive impairment progressively interferes with decision-making, especially in the final stages of the disease, generating conflicts regarding autonomy and clinical care. Advance Directives and Advance Care Planning offer the opportunity to reflect on values, desires, and future care preferences, as well as the possibility to communicate them to family members and care teams, promoting respect for autonomy and reducing conflicts associated with care, especially in the terminal stage. In Chile, there has been gradual progress, but it is still a challenge to implement the strategies to consolidate this process, overcoming existing barriers and maximizing its benefits.
RESUMO
BACKGROUND: The main purpose of this study was to establish the prevalence of antibodies against five transfusion-transmissible infections (TTIs) in blood donors from one of the most important blood banks in Colombia. METHODS: A cross-sectional, descriptive and case control study was performed from a database of Higuera-Escalante blood bank, for a period of a year. Serum was used for donor screening. Surface antigens for hepatitis B (HbsAg), anti-hepatitis C antibodies, Chagas disease, syphilis, and HIV were identified. Chemiluminescent Microparticle Immunoassay (CMIA, Abbott Diagnostics) was performed. RESULTS: From 41,575 total donors analyzed, 1,226 were reactive for any of the infectious markers (total prevalence of 2.95%). The prevalence of specific infections was: Chagas disease 0.49%, HbsAg 0.21%, HCV 0.45%, HIV 0.12%, and syphilis 1.68%. Reactivity was more frequent in men (n = 785, 64%) with a mean age of 36.35 years. HIV was present in the youngest donors with a mean age of 26.5 years (IC 95%: 23.6 - 27.6); on the other hand, Chagas disease was found in the oldest donor population, with a mean age of 40 years (IC 95%: 39.1 - 41.3). CONCLUSIONS: Identifying the prevalence of circulating antibodies against transfusion transmissible infections allows us to establish an epidemiological profile of donors inhabiting the geographic catchment area of our blood bank. Total prevalence in this study was 2.95% for any of the five markers. Syphilis prevalence demonstrates its high distribution within the blood donor population of our country, although this result could be influenced by the high rate of false-reactive test. Chagas disease is endemic in Santander, Colombia, which correlates with the results obtained in this study.
