Background: Exposure to 2.5-micron diameter air pollutants (PM 2.5) has been associated with an increased risk of illness and death worldwide; however, in Latin American health impacts assessment of this risk factor is scarce. Medellín is one of the most polluted cities in the region, with a population growth rate that is twice as high as that of other Colombian cities, which implies a growing population at risk. Methods: A descriptive study of the disease burden was carried out using the city as the unit of observation. Health events were selected based on epidemiologic evidence and the availability of the population attributable fraction associated with PM 2.5. The mortality records were taken from the module of deceased of the Single Registry of Affiliates of the Health System; the morbidity records were taken from the Individual Health Services Registries. For the estimation of the burden of disease, the current Global Burden of Disease guidelines were followed. Results: Attributable disability-adjusted life years to exposure to ambient PM 2.5 pollution (DALYs PM2.5) constituted 13.8% of total burden of the city. Males showed the greatest loss of DALYs PM2.5 due to acute events, while in women the greatest loss was due to chronic events. Ischemic heart disease, chronic diseases of the lower respiratory tract, and influenza and pneumonia were the events that contributed the most to DALYs PM2.5. 71.4% of the DALYs PM2.5 corresponded to mortality, mainly in the population over 65 years of age. Regarding attributable morbidity, acute events were more prevalent in both sexes, especially due to respiratory diseases Conclusion: Premature death among the elderly population has the greatest weight on burden of disease attributable to ambient PM 2.5 pollution, mainly due to respiratory and cardiovascular diseases, without significant differences according to gender.

BACKGROUND: COVID-19, caused by SARS-CoV-2, is a global pandemic that has been an immense burden on healthcare systems all over the world. These patients may be at higher risk for acute ischaemic stroke (AIS). We present our experience with AIS in patients with COVID-19. METHODS: We reviewed all patients admitted to our hospital during a 6-week period with a positive nasopharyngeal swab test for SARS-CoV-2. Among these patients, we identified AIS. We reviewed the demographics, clinical, laboratory, imaging characteristics, treatments received and outcomes of AIS in patients with COVID-19. RESULTS: We identified 683 patients admitted with COVID-19 during the study period, of which 20 patients had AIS. Large-vessel occlusion (LVO) was noted in 11 patients (55%). Intravenous alteplase was administered in four patients (20%) and mechanical thrombectomy was performed in five patients (25%). Respiratory symptoms preceded the onset of AIS in most of the patients (70%) by 1 to 21 days. Mortality in patients with AIS was 50% compared with 26% of all COVID-19 admissions. Most of these patients died due to non-neurological causes (70%). Three patients with AIS had clinical and imaging findings consistent with COVID-19, but were negative for multiple nasopharyngeal swab tests. INTERPRETATION: LVO was more common in patients with AIS and COVID-19. They had more severe disease and higher mortality rates. Most of the patients had respiratory symptoms preceding AIS by days to weeks. This could explain certain patients with clinical picture of COVID-19 but negative nasopharyngeal swab tests.

Introducción: El efecto deletéreo de material particulado fino exterior sobre la salud respiratoria de la población de niños y de adultos mayores, es de interés en salud pública. Objetivo: Establecer el efecto de la contaminación por Material Particulado de menos de 2,5 μm de diámetro (PM2,5), sobre la Enfermedad Respiratoria Aguda (ERA) en los menores de 5 y personas de mínimo 65 años, ajustado por variables meteorológicas y climáticas, en los municipios del Área Metropolitana del Valle de Aburrá (Colombia), 2008 a 2015. Materiales y métodos: Estudio ecológico con información de la red de vigilancia de calidad del aire y de registros de prestación de servicios de salud. Se construyeron Modelos Aditivos Generalizados con función de enlace Poisson y suavización spline. Para cada rezago distribuido se calculó la medida de la asociación e intervalo de confianza. Resultados: Los casos de ERA aumentaron significativamente en los menores de 5 años en Envigado y Caldas (43,3% vs 29,6%) y en los de 65 y más años, en Medellín (13,2%) por cada incremento de 10 µg/m3 en PM2,5 al día quince a partir de la exposición. Conclusiones: Los eventos diarios respiratorios tuvieron especial frecuencia en Medellín y en municipios de la zona sur.
Introduction: The harmful effect of fine particulate matter on the respiratory health of child and elderly populations is a concern for public health. Objective: To establish the effect of pollution by less than 2.5 μm in diameter (PM2.5) particulate matter on Acute Respiratory Disease (ARD) during 2008-2015 in children younger than 5 and adults older than 65 from the Metropolitan Area of the Aburrá Valley (Colombia), adjusting for meteorological and climate variables. Materials and methods: Ecological study with information from the air quality surveillance network and individual records of health providers. Generalized Additive Models were developed using smoothing spline Poisson models. The assessment of the association and confidence intervals were calculated for each distributed lag. Results: For each 10 µg/m3 increment in PM2,5 and the day 15 post-exposure, ARD cases increased significantly in populations who are younger than 5 and older than 65 in Envigado and Caldas (43.3% vs. 29.6%) and Medellín (13.2%), respectively. Conclusions: Daily respiratory events had a special frequency in Medellín and the municipalities of the southern region.

Objetivo : estudiar desde el punto de vista bacteriológico el líquido cefalorraquídeo (LCR) de pacientes con sospecha de meningitis bacteriana (MB), detreminar la sensibilidad y especificidad del Gram y el látex frente al cultivo y conocer los grupos etáreos más afectados por la entidad. Métodos : Se trata de un estudio descriptivo, retrospectivo, para el cual se recogió la información de los años 1990 a 1993, se elaboró una encuesta que permitió cruzar las variables de edad y germen aislado, Gram y látex, y éstas últimas con el cultivo. Para esto se utilizó el sistema EPI-INFO 5.0 Resultados : se estudiaron 459 LCR. En 69 porciento de los pacientes no se encontró etiología bacteriana. La Neisseria meningitidis fue la primera causa en 16.2 porciento de los pacientes, le siguió el Haemophilus influenzae en 6.5 porciento y por último el Streptococcus pneumoniae en 2.8 porciento. El grupo más afectado fue el de 5 a veinte años con 144 pacientes, seguido del de uno a cuatro años con 120. La sensibilidad del Gram fue mejor que la del látex en el caso de N. meningitidis y S. pneumoniae, pero igual para el H. influenzae. Conclusiones : 1. Promover estudios locales y nacionales que permitan conocer los cambios en las tasas de incidencia. 2. Utilizar el Gram como un método de diagnóstico barato, ráapido, simple y sensible, siempre y cuando se tenga experiencia. 3. Hacer únicamente látex en casos en el el Gram no aprte información o si el paciente ha estado recibiendo antibióticos.
