Background: There is a paucity of validated instruments for screening depression in adolescent populations in Chile. Aim: To determine the diagnostic accuracy of the adolescent version of Patient Health Questionnaire-9 (PHQ-9). Material and Methods: The PHQ-9 was transculturally adapted and administered to adolescents aged 15 to 19 years residing in Santiago de Chile, who were then evaluated with a semi structured interview (Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version or K-SADS-PL) and the Beck Depression Inventory. Internal validity, concurrent validity, and discriminatory power of the PHQ-9 were analyzed. Results: We evaluated 245 adolescents aged 16.2 ± 1 years (71% females). Two hundred and ten presented with a depressive episode and 35 were healthy. The sensitivity and specificity of the scale were 86.2 and 82.9% for 11 points, with a positive likelihood ratio of 5.02. Conclusions: The PHQ-9 is sensitive and specific enough to be used as a screening tool in adolescents with suspected depression. At a 11-point cut-off score as proposed, the likelihood to find a positive result in a subject with depression is five times higher.

RESUMO Objetivos Avaliar a qualidade da consultoria em saúde mental nos centros de atenção primária à saúde e possível relação com a taxa de internação psiquiátrica. Métodos Um estudo de delineamento transversal ecológico foi conduzido em nível nacional em 502 centros de atenção primária à saúde (87,3% do número total no país) em 275 municípios no Chile em 2009. A prática de consultoria em saúde mental foi caracterizada de acordo com quatro critérios: disponibilidade, frequência, continuidade dos participantes e continuidade nos níveis de atenção. Também foi criada uma variável dicotômica, denominada “consultoria ideal”, quando os quatro critérios eram satisfeitos. Foi usado um modelo de regressão de quase-Poisson para estimar a taxa de internação por diferentes transtornos psiquiátricos, ajustada segundo as características da população. Resultados Ao todo, 28,3% dos centros de atenção primária à saúde tiveram uma prática de consultoria ideal no ano anterior, concentrada nos municípios pertencentes aos quartis mais pobre e mais rico. A continuidade da atenção foi o critério satisfeito com menor frequência (38,3%). A prática de consultoria ideal ao nível de município foi associada a um número menor de altas psiquiátricas, com as seguintes razões de taxas de incidência e intervalos de confiança de 95% (IC 95%): 0,65 para esquizofrenia (IC 95% 0.49–0.85); 0,68 para outras psicoses (IC 95% 0.52–0.89) e 0,66 para transtornos de personalidade (IC 95% 0.49–0.89). Os municípios com prática de consultoria ideal tiveram 2,44 menos altas psiquiátricas por 10 mil habitantes, embora não seja estatisticamente significativo (–0.85 a 5,70). Conclusões O estudo de uma amostra representativa da população nacional revelou que a consultoria em saúde mental na atenção primária esteve associada a um número menor de internações psiquiátricas. Outros estudos são necessários para entender o papel de cada componente da consultoria em saúde mental.

ABSTRACT Objectives To assess the quality of consultation liaison across all primary health care centers in Chile, and its potential relationship with the psychiatric hospitalization rate. Methods We carried out a countrywide ecological cross-sectional study on 502 primary health centers in 275 municipalities (87.3% of total primary health centers in Chile) during 2009. We characterized the presence of consultation liaison using four criteria: availability, frequency, continuity of participants, and continuity across care levels. We also created a dichotomous variable called “optimal consultation liaison” for when all four criteria were met. A quasi-Poisson regression model was used to estimate the rate of hospitalization due to different psychiatric disorders, adjusting by population attributes. Results Of the primary health centers, 28.3% of them had had optimal consultation liaison during the preceding year, concentrated in the poorest and richest municipalities. Continuity of care was the criterion that was met least often (38.3%). The presence of optimal consultation liaison at the municipal level was associated with fewer psychiatric discharges, with the following incidence rate ratios and 95% confidence intervals (CIs): schizophrenia, 0.65 (95% CI: 0.49–0.85); other psychoses, 0.68 (95% CI: 0.52–0.89); and personality disorders, 0.66 (95% CI: 0. 49–0.89). Municipalities with optimal consultation liaison showed 2.44 fewer total psychiatric discharges per 10 000 inhabitants, although without reaching statistical significance (-0.85 to 5.70). Conclusions Using a nationally representative sample, we found that consultation liaison in primary care was associated with having fewer psychiatric hospitalizations. More studies are required to understand the role of each component of consultation liaison.

RESUMEN Objetivos Evaluar la calidad de las consultorías de salud mental en todos los centros de atención primaria de salud en Chile y su posible relación con la tasa de hospitalización psiquiátrica. Métodos Se llevó a cabo un estudio transversal ecológico a nivel nacional sobre los 502 centros de atención primaria de salud en 275 municipios (87,3 % del total de los centros de atención primaria de salud en Chile) durante el 2009. Las consultorías de salud mental se caracterizaron por medio de cuatro criterios: disponibilidad, frecuencia, continuidad de los participantes y continuidad en los distintos niveles de atención. Además, se creó una variable dicótoma llamada “consultoría óptima” para cuando se cumplían los cuatro criterios. Se utilizó un cuasimodelo de regresión de Poisson para calcular la tasa de hospitalización a causa de distintos trastornos psiquiátricos, ajustada por los atributos de la población. Resultados De los centros de atención primaria de salud, el 28,3 % había presentado consultorías óptimas durante el año anterior, concentradas en los municipios más pobres y más ricos. La continuidad de la atención fue el criterio que se cumplió con menos frecuencia (38,3 %). La presencia de consultorías óptimas a nivel municipal estuvo asociada con menos altas médicas psiquiátricas, con la siguiente razón de tasa de incidencia e intervalos de confianza (IC) del 95 %: esquizofrenia, 0,65 (IC del 95%: 0,49–0,85); otras psicosis, 0,68 (IC del 95%: 0,52–0,89); y trastornos de la personalidad, 0,66 (IC del 95%: 0,49–0,89). Los municipios con consultorías óptimas registraron 2,44 menos altas médicas psiquiátricas totales por 10 000 habitantes, aunque sin alcanzar significación estadística (-0,85 a 5,70). Conclusiones Por medio de una muestra representativa a nivel nacional, encontramos que las consultorías de salud mental en centros de atención primaria de salud estaban asociadas con la disminución de hospitalizaciones psiquiátricas. Se requieren más estudios para comprender la función de cada componente de las consultorías de salud mental.

Background: Chilean AIDS Cohort is the oldest and extensive in Latin America and one of most numerous and with longer follow up time to international level. Records information from 14,873 patients out of approximately 22,000 in antiretroviral therapy in the public system and its results have allowed to know the national reality and have contributed to the adoption of public policies. Aim: To describe the demographic, clinical and immunological characteristics of patients who have started ART in Chile and its evolution over the past 15 years. Patients and Methods: The cases were stratified by five-year periods: 2001-2005, 2006-2010 and 2011-2015. The data analysis included calculating proportions, their respective confidence intervals 95% and X² test for significance analysis was applied. Results: 17.4% of patients starting ART are women and the proportion has remained relatively constant. The highest proportion of new HIV cases are 30 and 39 years old, nevertheless the layer of 15-29 years demonstrates a significant increase from 21.7 to 36.4% in 2011-2015 especially in men. 12.1% of new cases are older than 50 years old with a stable trend over time; however, women over 50 have increased from 11.0 to 15.6%. Antiretroviral therapy initiation with CD4+ T lymphocytes less than 200 cells/mm³ has decreased from 79.7 to 42.4% and in stage C from 45.4 to 22.6%. Late presentation to antiretroviral therapy is higher in men but this gap has narrowed in the last five years. Pneumocystis jiroveci, wasting syndrome, tuberculosis, Kaposi’s sarcoma and esophageal candidiasis are the most common opportunistic diseases without significant changes in the three-year periods analyzed. In the last five years, 15.5% of opportunistic diseases occurs in patients with CD4+ TL > 200 cells/mm3. Discussion: Despite the limitations of observational studies present report describes the characteristics and evolution of the epidemics in Chile in the last 15 years. The infection occurs at younger ages in men, whereas in women there is an increase over 50 years old. Despite advances in treatment access have reduced late presentation to therapy, important challenges remain to achieve more timely initiation of antiretroviral therapy in accordance with WHO 90-90-90 goals.

Introducción: La Cohorte Chilena de SIDA es la más antigua y extensa de Latinoamérica y una de las más numerosas y con mayor tiempo de seguimiento a nivel internacional. Registra información de 14.873 pacientes de los aproximadamente 22.000 en TARV en el sistema público y sus resultados han permitido conocer la realidad nacional y han contribuido a la adopción de políticas públicas. El objetivo de este estudio es describir las características demográficas, clínicas e inmunológicas de los pacientes que han comenzado TARV en Chile y su evolución en los últimos 15 años. Pacientes y Métodos: Los casos fueron estratificados por quinquenios: 2001-2005, 2006-2010 y 2011-2015. El análisis de los datos incluyó el cálculo de proporciones, sus respectivos intervalos de confianza 95% y se aplicó test de X² para análisis de significación. Resultados: El 17,4% de los casos que inician TARV corresponde a mujeres y la proporción se ha mantenido relativamente constante. Por edad, destaca el grupo de adultos entre 30 y 39 años aunque el estrato de 15-29 años evidencia un importante aumento desde 21,7 a 36,4% en 2011-2015, especialmente en hombres. Un 12,1% del total de los inicios de TARV son mayores de 50 años con una tendencia estable en el tiempo; sin embargo, las mujeres mayores de 50 años han aumentado de 11,0 a 15,6%. El inicio de TARV con LT CD4 menor de 200 céls/mm³ ha disminuido desde 79,7 a 42,4% y en etapa C desde 45,4 a 22,6%. La presentación tardía a TARV es mayor en hombres pero esta diferencia se ha reducido en el último quinquenio. Neumonía por Pneumocystis jiroveci, síndrome consuntivo, tuberculosis, sarcoma de Kaposi y candidiasis esofágica son las enfermedades oportunistas más frecuentes sin cambios significativos en los tres quinquenios analizados. En el último quinquenio, 15,5% de las enfermedades oportunistas se presenta en pacientes con LT CD4 > 200 céls/mm³. Discusión: Pese a las limitaciones de los estudios observacionales el presente reporte describe las características y evolución de la epidemia en Chile en los últimos 15 años. La infección se presenta a edades más jóvenes en hombres, mientras que en mujeres hay un aumento en mayores de 50 años. Pese a los avances en acceso a tratamiento que han permitido reducir la presentación a tardía a terapia, aún persisten importantes desafíos para alcanzar un inicio de TARV más oportuno, en concordancia con las metas 90-90-90 de OMS.

Objective: To determine frequency and types of vulvovaginal hygienic habits that Chilean women have. Methods: Cross-sectional study in 271 adult women who attended primary gynecological centers of public and private systems. A survey of 7 questions with closed-answer alternatives was undertaken by a physician in order to determine frequency and type of intimate hygiene. Descriptive statistics were performed by using univariate and multivariate models, expressing the magnitude of association as Odds Ratio. Multivariate models with higher variance were selected by stepwise selection. Results: 25% washed their genitals once a day, 32% twice a day, 28% three times a day and 13% four or more times a day. Women attending public centers tend to wash their genitals two or three times a day, while the ones attending private centers do this mostly once or twice a day. 56% of women - especially those treated in private centers - use additional elements apart from water, preferably special soaps. Older and postmenopausal women were associated with the use of additional elements other than water. Diabetics were 3 times more likely to use a special soap than non-diabetics. Conclusions: 85% of chilean women of both health-care systems perform intimate hygiene between one and three times a day; 56% of them and 75.6% of those attending private centers use elements other than water, preferably special soaps.

Objetivo: Determinar la frecuencia y tipos de hábitos higiénicos vulvo-vaginales en mujeres chilenas. Métodos: Estudio de corte transversal en 271 usuarias adultas que asistieron a centros ginecológicos primarios del sistema público y privado. Médico aplicó una encuesta de 7 preguntas con alternativas de respuestas cerradas para pesquisar la frecuencia y tipo de hábitos higiénicos íntimos. Se realizó estadística descriptiva utilizando modelos univariados y multivariados, expresando la magnitud de asociación como Odds Ratio. Se seleccionaron los modelos multivariados con mayor varianza mediante selección por pasos. Resultados: Un 25% lava sus genitales una vez/día, 32% dos veces/día, 28% tres veces/día y 13% cuatro o más veces/día. Las mujeres del sistema público tienden a un aseo genital con frecuencias de dos a tres veces al día, mientras que las del sistema privado mayormente una y dos veces al día. El 56% de las mujeres, especialmente aquellas atendidas en consultas privadas, utiliza algún otro elemento adicional al agua, preferentemente jabones especiales. Las mujeres mayores y postmenopáusicas se asociaron a lavados genitales con elementos adicionales al agua. Las diabéticas presentaron una probabilidad 3 veces mayor de usar un jabón especial que las no diabéticas. Conclusiones: Mujeres chilenas de ambos sistemas de atención, realizan aseo íntimo con una frecuencia entre una y tres veces al día en el 85% de las encuestadas. El 56% de ellas y el 75,6% de las que consultan en el sistema privado utilizan para el aseo genital algún otro elemento adicional al agua, preferentemente jabones especiales.

Background: Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) is a condition of dialysis patients associated with both morbidity and mortality. Management is based on clinical guidelines with goals that are hard to comply with. Aim: To describe and compare biochemical variables associated with this disorder in two different time periods. Material and Methods: Revision of medical records of 814 patients (49% females) dialyzed during 2009 and 1018 patients (48% females), dialyzed during 2012 in Southern Metropolitan Santiago. Information about serum calcium, phosphorus, parathyroid hormone (PTH) and albumin was retrieved. Results: Median PTH values in 2009 and 2012 were 222.5 and 353.5 pg/ml respectively (p < 0.05). The figures for serum calcium corrected by albumin were 9.0 and 8.5 mg/dl respectively (p < 0.05). The figures for phosphorus were 4.7 and 5.0 mg/dl respectively (p < 0.05). The Calcium x Phosphorus product was 41.4 and 42.5 mg²/dl² (p < 0.05). Of note, the proportion patients with serum calcium below recommended levels (< 8.4 mg/dl) increased from 16% to 40% from 2009 to 2012. The proportion of patients with biochemical variables within recommended ranges was lower in 2012 than in 2009. Conclusions: There was a low proportion of patients with bone metabolism parameters within ranges recommended by clinical guidelines. These parameters were worst in 2012.

Background: Surgical lung resection is required for multiple pulmonary diseases. After these procedures, the lung experiences a compensatory growth, which can be studied in animal models such as rats. Aim: To develop a surgical model of lung lobectomy in rats. Material and Methods: Forty seven rats of the strain Rattus norvegicus were used. Animals were anesthetized with atropine, ketamine and xylacine. The airway was managed with a facial mask to avoid intubation. An anesthetic evaluation protocol was followed and animals were oxygenated using a cephalic veil. Forty rats were subjected to a right lobectomy and seven animals were sham operated. Rats subjected to lobectomy were sacrificed at one, two, three and four weeks after operation. Results: All operated rats survived. There were significant differences in the number of alveolar intersections among rats subjected to lobectomy and sacrificed at three weeks compared to sham operated animals, with a lower number of alveoli among the former. Conclusions: We were able to develop the model of lobectomy, however we failed to demonstrate a compensatory growth among rats subjected to lobectomy.

Introducción: En la literatura está documentado que diferentes mamíferos tienen la capacidad de crecimiento compensatorio post resección pulmonar parcial. Objetivo: Crear un modelo quirúrgico de lobectomía en ratas, factible de desarrollar en nuestro medio, exponiendo algunas originalidades en relación a procedimientos de ventilación pulmonar, comunicando los resultados de la densidad alveolar obtenidos. Animales y Métodos: Se utilizaron 47 ratas Rattus norvegicus. Se aplicó como anestesia Atropina, Quetamina y Xilacina. Para el manejo de la vía aérea se diseñó: 1. Un sistema de ventilación con máscara facial tipo ambú evitando así la intubación traqueal. 2. Un protocolo de evaluación anestésica. 3. Un halo para oxigenar. 4. Se modificó un estetoscopio para realizar auscultación animal. Se practicó una lobectomía pulmonar derecha. Los sujetos fueron separados en Grupo Control (n = 7) y Grupo Experimental (n = 40), estos últimos, separados en cuatro grupos (n = 10, cada grupo), que fueron sacrificados en las semana 1, 2, 3 y 4. Resultados: Se logró 100% de sobrevida. El número de intersecciones alveolares mostró diferencias significativas entre el grupo control y el grupo experimental sacrificado en la semana 3 (p = 0,0016), con un menor número de alvéolos en el grupo experimental. Conclusión: Es factible realizar un modelo de cirugía pulmonar en ratas, con obtención de un 100% de sobrevida. Esto se logra por adecuaciones en el manejo pre e intra-operatorio. No se pudo demostrar que exista aumento significativo en el número de alvéolos, posiblemente por el bajo número de casos realizados.

Congenital hearing loss is the total or partial inability to hear sounds through the ears. It is the most common disability in newborns in Chile and worldwide, and is a permanent condition. The direct impact on children who are not adequately diagnosed is the alteration in acquisition of language and cognitive skills and a decline in their social and school insertion, jeopardizing their professional and potentially productive life. Universal screening programs for hearing loss are essential for the diagnosis, since 50% of infants with hearing loss have no known risk factor. Screening before one month of age, confirmation before 3 months, and effective intervention before 6 months, allows the development of these children as if they had normal hearing. In Chile there is a selective program of screening for infants aged less than 32 weeks or 1,500 grams, as part of Explicit Health Guarantees, but it covers only 0.9% of newborns per year. Therefore, a large majority of children remain without diagnosis. The aim of this review is to compare the situation in Chile with other countries, raising the need to move towards a universal neonatal hearing loss screening program, and propose necessary conditions in terms of justification and implementation of a universal screening public policy.

Background: The detection of cognitive changes (CC) and psychiatric disorders in relapsing remitting multiple sclerosis (MS-RR) contributes to patient clinical monitoring. Aim: To assess the frequency and characteristics of CC and psychiatric disorders in Chilean patients with MS-RR, before starting immunomodulatory treatment. Patients and Methods: Retrospective review of data that was obtained following a standard assessment protocol. It consisted in the application of the Expanded Disability Status Scale of Kurtzke (EDSS), Multiple Sclerosis Functional Composite (MSFC), fatigue intensity scale of Krupp, brief repeatable battery of neuropsychological Rao (BRN-R) and Hamilton's depression and anxiety questionnaires. Results: We evaluated 129 patients aged between 12 and 60 years of age (69% women). Ninetyfour percent of patients had eight or more years of schooling. The average EDSS score was 2.83. CC were detected in 62% of participants, in at least one subtest of the BRN-R. The main changes were verbal memory and speed in the processing information. The frequency of cognitive impairment (CI), defined as at least two BRN-R subtests altered, was 36%. The figures decreased to 17% when significant major depression or associated fatigue were excluded. Depressive symptoms were observed in 58% and anxiety in 76.7%. Conclusions: The results are consistent with those described in the literature. The type of instruments used in the investigation of CC and the definition of CI in MS should be standardized.

Social status (SS) is a multidimensional variable that is used widely in health research. There is no single optimal method for estimating social status. Rather, in each case the measurement may vary depending on the research subject, the base theory considered, the population of interest, the event of interest and, in some cases, the available information. This literature review develops the following topics related to SS measurement, based on the international scientific sources available electronically: i) identification of the role of SS in the context of social epidemiology research, ii) description of the principal indicators and methodological approaches used to measure SS in health research, and iii) analysis of the distinct difficulties of SS measurement in specific populations such as ethnic groups, women, children, the elderly, and in rural vs. urban contexts. The review finally makes it possible to describe some of the implications of SS measurement in Latin American countries.

La posición social (PS) es una variable multidimensional ampliamente utilizada en la investigación en salud. No hay una sola forma óptima de estimarla, sino que en cada caso su medición varía de acuerdo con la pregunta de investigación, la teoría considerada de base, la población de interés, el evento de interés y, en algunos casos, la información disponible. Esta revisión de literatura desarrolla los siguientes aspectos relacionados a la medición de la PS a partir de fuentes electrónicas científicas internacionales disponibles: i) identifica el rol de la PS en el contexto de la investigación epidemiológica social, ii) describe los principales indicadores y enfoques metodológicos utilizados para medir la PS en investigación en salud y iii) analiza las dificultades particulares de medir la PS en poblaciones específicas como grupos étnicos, mujeres, niños, ancianos y contextos rurales versus urbanos. La revisión permite finalmente describir algunas de las implicancias de la medición de PS en países de América Latina.

This paper describes the evaluation of the first training on clinical research methodology in Chile (EMIC-Chile) 12 months after its completion. An online survey was conducted for students and the Delphi method was used for the teaching team. Among the students, the majority reported that the program had contributed to their professional development and that they had shared some of the knowledge acquired with colleagues in their workplace. Forty-one percent submitted a project to obtain research funding through a competitive grants process once they had completed the course. Among the teachers, the areas of greatest interest were the communication strategy, teaching methods, the characteristics of the teaching team, and potential strategies for making the EMIC-Chile permanent in the future. This experience could contribute to future research training initiatives for health professionals. Recognized challenges are the involvement of nonmedical professions in clinical research, the complexities associated with the distance learning methodology, and the continued presence of initiatives of this importance at the national and regional level.

Este trabajo describe la evaluación del primer "Entrenamiento en Metodología de Investigación Clínica en Chile (EMIC-Chile) tras 12 meses de haber finalizado. Se aplicó una encuesta online para alumnos y el método Delphi para el equipo docente. Entre los estudiantes, la mayoría informó que el programa apoyó su desarrollo profesional y que transmitieron los conocimientos en su lugar de trabajo. El 41% presentó un proyecto a fondos concursables de investigación una vez finalizado el curso. Entre los profesores, las áreas de mayor interés fueron la estrategia comunicacional, la metodología educativa, las características del equipo docente y las posibles estrategias de permanencia de EMIC-Chile a futuro. Esta experincia podría servir a futuras iniciativas de formación en investigación para profesionales de la salud. Se reconocen como desafíos la incorporación de profesiones no médicas en la investigación clínica, complejidades asociadas a la metodología semi-presencial y permanencia duradera de iniciativas de esta envergadura a nivel nacional y regional.

OBJECTIVE: To describe the burden of disease studies made in the region, identify the main priorities in health from the indicator Disability Adjusted Life Years (DALYs). MATERIAL AND METHODS: By the use of DALYs identify the burden of disease in the countries in the network. RESULTS: DALYs emphasize the emergency of mental disorders, diabetes mellitus in women and the disorders associated with alcohol consumption and injuries in men. CONCLUSIONS: Latin America is the region with more national studies of burden of disease, using a standardized methodology, that allows identifying new health priorities which are pressing to the health services; for that reason these results constitute an element to take into account in the establishment of public policies in each country.
