Local attributable burden disease to PM 2.5 ambient air pollution in Medellín, Colombia, 2010-2016.

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.

Disability-Adjusted Life Years Due to Mental Disorders and Diseases of the Nervous System in the Population of Medellin, 2006-2012. / Años de vida saludable perdidos a causa de trastornos mentales y enfermedades del sistema nervioso de la población de Medellín, 2006-2012.

OBJECTIVE: To determine the healthy life years (HLY) lost as a result of mental disorders and nervous system diseases in Medellin from 2006 to 2012. METHODS: Descriptive study using a secondary information source according to the Global Burden of Disease (GBD) framework. To calculate the years of potential life lost (YPLL), we used vital statistics data; to calculate disability-adjusted life years (DALY), we used morbidity data from individual records managed by health service providers, outpatient clinics and other research studies. HLY are the sum of YPLL and DALY. RESULTS: In Medellin, from 2006 to 2012, out of 1,242,407 HLY related to mental disorders and nervous system diseases, the vast majority (99.39%) were due to disability. Most HLY were found in females (70.22%) and 81% were found in people aged 15 to 59. The disorders representing the greatest burden were unipolar depressive disorder (81%), Alzheimer's disease and other types of dementia (4.82%), schizophrenia (3.5%) and drug use disorders (2.78%). CONCLUSIONS: Our results indicate a significant increase in the disease burden due to mental disorders and nervous system diseases. Public policy decision-makers in the city of Medellin should take note, as health problems of this type can result in a substantial rise in healthcare costs.

Lingual function in children with anterior open bite: A case-control study.

The position of the tongue during phonation and swallowing can modify the position of the teeth and even the growth of the jaws. OBJECTIVE: To determine the association between the position of the tongue and phonation among individuals with normal vertical overbite (NVO) and anterior open bite (AOB). MATERIALS AND METHODS: This was a case-control study of 132 students with AOB and 132 controls with NVO between the ages of 8 and 16 years old. The presence of AOB was determined during a clinical examination using a Boley gauge, phonation (speech) was assessed with an articulation test, which was analysed using a classification table of Spanish consonants spoken in Colombia, and tongue contact during swallowing was determined with the Payne test. Associations were determined between AOB and the position of the tongue upon swallowing and during speech (Chi2 test of independence, Fisher's exact test, and Mann-Whitey U test, P<0.005). Finally, a logistic regression model was performed, with AOB as the dependent variable. RESULTS: We found associations between AOB and the presence of lingual interposition, distortion, lingual thrust, protrusion of the tongue, contact with palatine rugae, and type of dentition (P<0.05). According to the logistic regression model, the presence of lingual thrust (odds ratio (OR): 0.067; 95% confidence interval (CI): 0.009-0.518) and contact with the palatine rugae (OR: 0.420; 0.216-0.818) behave as protective factors associated with the presence of AOB, and the presence of distortion was found to be a risk factor (OR: 10.751; 95%CI: 5.658-20.427). CONCLUSION: Lingual thrust, interposition, and protrusion are associated with AOB. Lingual thrust and contact of the tongue with the palatine rugae behave as protective factors, and the presence of distortion acts as a risk factor.

Años de vida saludable perdidos a causa de trastornos mentales y enfermedades del sistema nervioso de la población de Medellín, 2006-2012 / Disability-Adjusted Life Years Due to Mental Disorders and Diseases of the Nervous System in the Population of Medellin, 2006-2012

RESUMEN Objetivo: Determinar la pérdida de años de vida saludables (AVISA) por trastornos mentales y enfermedades del sistema nervioso en Medellín, de 2006 a 2012. Métodos: Estudio descriptivo, con fuente de información secundaria bajo lineamientos teóricos del Estudio la Carga Global de la Enfermedad (CGE). Para calcular los Años Potenciales de Vida Perdidos (APVP), se empleó información de las estadísticas vitales; para los Años de Vida Ajustados por Discapacidad (AVD), la de morbilidad de los Registros Individuales de Prestación de Servicios de Salud (RIPS), de consulta externa y otras investigaciones. Los AVISA se obtuvieron de sumar los APVP y AVD. Resultados: En Medellín, durante el septenio, de 1.242.407 AVISA por trastornos mentales y enfermedades del sistema nervioso, la mayor carga se debió a discapacidad (99,39%). Las mujeres aportaron más AVISA (70,22%). El 81% de los AVISA se concentraron en el grupo de 15 a 59 años. Los trastornos que mayor carga representaron fueron, en este orden, el trastorno depresivo unipolar (81%), el Alzheimer y otras demencias (4,82%), la esquizofrenia (3,45%) y los trastornos por consumo de drogas (2,78%). Conclusiones: Se sustenta un importante incremento de la carga de la enfermedad por trastornos mentales y enfermedades del sistema nervioso, lo que debe llamar la atención de los tomadores de decisiones sobre la política pública del municipio, ya que estos problemas de salud pueden significar un gran aumento en los costos de atención en salud.
