Trends in vasectomy and sexually transmitted diseases in Chile: findings from robust national databases / Tendencias de la vasectomía y las enfermedades de transmisión sexual en Chile: resultados de bases de datos robustas / Tendências em vasectomia e doenças sexualmente transmissíveis no Chile: resultados de bases de dados robustas

Abstract: A controversy about the increase or decline of vasectomy is emerging; however, the evidence is still scarce in Latin America. This ecological study analyzed the vasectomy and sexual transmitted diseases (STD) trends over a period of 10 years in Chile and determined if there is any relationship between them. We conducted a mixed ecological study using secondary and representative data on the number of vasectomies and STD cases from 2008 to 2017. Vasectomy rates were calculated for age-specific groups of men aged 20-59 years, and specific STD (HIV, chlamydia, gonorrhea, trichomoniasis, and syphilis) for the same period. Multivariate negative binomial regression models were fitted to evaluate rate trends and relationships. The mean vasectomy age was 40.3 years, with no significant differences between the years of the study (p = 0.058). The overall vasectomy rate significantly increased from 2008 to 2017 (p < 0.001), with differences between age groups (p < 0.001). The most significant increase was observed in men aged 30-49 (p < 0.001). The STD rates significantly increased (p < 0.05) during the study period. A significant positive correlation was found between vasectomy and gonorrhea incidence rates (p = 0.008) and an inverse correlation was found with hepatitis B incidence rates (p = 0.002). Vasectomy trends and STD rates significantly increased from 2018 to 2017 in Chile. especially among men aged 30-49 years. The relationship between vasectomy and STD increments suggests a new risk factor for reproductive and sexual health policies to aid controlling the HIV and STD epidemic.

Resumen: Se viene surgiendo una controversia sobre el aumento o la disminución de la vasectomía; sin embargo, la evidencia aún es escasa en América Latina. Este estudio ecológico analizó las tendencias de la vasectomía y las enfermedades de transmisión sexual (ETS) durante un período de 10 años en Chile y determinó si existe alguna relación entre ellas. Este es un estudio ecológico mixto que utiliza datos secundarios representativos sobre el número de vasectomías y casos de ETS de 2008 a 2017. Las tasas de vasectomía se calcularon por grupos de edad teniendo en cuenta a hombres entre 20-59 años de edad y ETS específicas (VIH, clamidia, gonorrea, tricomoniasis y sífilis) para el mismo período. Los modelos de regresión binomial negativa multivariante se ajustaron para evaluar las tendencias y las relaciones entre las tasas. La edad media de la vasectomía fue de 40,3 años, sin diferencias significativas entre el período del estudio (p = 0,058). La tasa general de vasectomía tuvo un incremento significativo para el período de 2008 a 2017 (p < 0,001), con diferencias entre los grupos de edad (p < 0,001). El incremento más significativo se observó en hombres de entre 30-49 años (p < 0,001). Las tasas de ETS tuvieron una alza significativa (p < 0,05) durante el período de estudio. Hubo una correlación positiva significativa entre las tasas de vasectomía y las tasas de incidencia de gonorrea (p = 0,008) y una correlación inversa con las tasas de incidencia de hepatitis B (p = 0,002). Se concluye que las tendencias de la vasectomía y las tasas de ETS presentaron un incremento significativo en período de 2008 a 2017 en Chile, especialmente entre los hombres de entre 30-49 años. La relación entre la vasectomía y el incremento de las ETS puede ser un nuevo factor de riesgo para las políticas de salud sexual y reproductiva que puede ayudar a controlar la epidemia del VIH y las ETS.

Resumo: Uma controvérsia sobre o aumento ou declínio da vasectomia está surgindo; no entanto, as evidências ainda são escassas na América Latina. Este estudo ecológico analisou as tendências de vasectomia e doenças sexualmente transmissíveis (DST) em um período de dez anos no Chile e determinou se há alguma relação entre elas. Este é um estudo ecológico misto utilizando dados secundários e representativos sobre o número de vasectomias e casos de DSTs de 2008 a 2017. As taxas de vasectomia foram calculadas por grupos etários, considerando homens de 20-59 anos de idade e DSTs específicas (HIV, clamídia, gonorreia, tricomoníase e sífilis) para o mesmo período. Modelos de regressão binomial negativa multivariada foram ajustados para avaliar tendências e relações entre taxas. A média de idade da vasectomia foi de 40,3 anos, sem diferenças significativas entre os anos do estudo (p = 0,058). A taxa geral de vasectomia aumentou significativamente de 2008 a 2017 (p < 0,001), com diferenças entre grupos etários (p < 0,001). O aumento mais significativo foi observado em homens de 30-49 anos (p < 0,001). As taxas de DST aumentaram significativamente (p < 0,05) durante o período de estudo. Houve correlação positiva significativa entre as taxas de vasectomia e as taxas de incidência de gonorreia (p = 0,008) e uma correlação inversa com as taxas de incidência de hepatite B (p = 0,002). As tendências de vasectomia e as taxas de DST aumentaram significativamente de 2008 para 2017 no Chile, especialmente entre homens de 30-49 anos. A relação entre vasectomia e incrementos de DST sugere um novo fator de risco para políticas de saúde sexual e reprodutiva para auxiliar no controle da epidemia de HIV e DST.

Salutogénesis de la alimentación en chile: actores involucrados y brechas detectadas / Nutritional Salutogenesis in Chile: key stakeholders and detected gaps

OBJETIVOS: Conocer los principales actores involucrados y las brechas detectadas en el proceso de aprendizaje alimentario de una población adulta urbana en Santiago de Chile. MATERIALES Y MÉTODOS: De una muestra de 100 beneficiarios de un CESFAM, se incluyó a quienes tuvieran un alto Índice de Alimentación Saludable (IAS). Se realizaron entrevistas semiestructuradas, las cuales fueron grabadas en audio, transcritas de manera textual y analizadas mediante la Teoría Fundamentada. RESULTADOS: Se entrevistó a 16 personas con IAS alto, en su mayoría mujeres. Los principales actores del proceso de aprendizaje alimentario resultan ser los padres, las experiencias adquiridas en el trabajo y la consulta con el profesional nutricionista. Se detectó una brecha de educación alimentaria entre la población general y el equipo de nutricionistas en contextos de atención primaria de salud. CONCLUSIONES: Los padres, los contextos laborales y la consulta con el nutricionista son las principales influencias en el proceso de aprendizaje alimentario. También fueron identificados tres grupos poblacionales (adolescentes femeninas, madres y niños), como poblaciones carentes de intervención nutricional de carácter educativo-preventivo por nutricionistas en el contexto de la atención primaria de salud en Chile, situación que podría perpetuar y mantener los malos hábitos de alimentación de la población general.

OBJECTIVES: To identify key stakeholders involved in the nutritional educational processes and detect gaps in this process in an urban adult population in Santiago, Chile. MATERIALS AND METHODS: From a sample of 100 individuals registered at a primary health care facility, those with a high Healthy Eating Index (HEI) were included in the study. Semi-structured interviews were conducted, which were recorded in audio, transcribed verbatim, and analyzed according to Grounded Theory. RESULTS: A total of 16 people with HEI were interviewed, who were mainly women. The main actors involved in the nutritional educational process turned out to be the individuals' parents, workplace experiences, and clinical consultations with professional nutritionists. A nutritional education gap was detected between the general population and teams of nutritionists in primary health care contexts. CONCLUSIONS: Parents, the workplace, and consultations with nutritionists are the main influences in the nutritional learning process. Three population groups (female adolescents, mothers, and children) were also identified as lacking educational and preventive interventions by nutritionists in the primary health care context in Chile; this situation could perpetuate and maintain unhealthy eating habits among the general population.

Asociación entre la calidad de vida relacionada con la salud y riesgo suicida en adolescentes: estudio transversal / Association of health-related quality of life and suicidal risk in adolescents: a cross-sectional study

INTRODUCCIÓN: El deterioro de la calidad de vida relacionada con la salud (CVRS) es un factor de riesgo de suicido en adultos; no obstante, poco se ha estudiado esta dimensión en adolescentes. OBJETIVO: Evaluar la asociación entre calidad de vida relacionada con la salud, medido con el EQ-5D-5L, y riesgo suicida en adolescentes y su capacidad de detección transversal de riesgo suicida. PACIENTES Y MÉTODO: 128 jóvenes (15-19 años) de la comuna de Puerto Aysén (Chile) respondieron transversalmente el EQ-5D-5L, la escala de suicidalidad de Okasha y dos preguntas de anclaje de riesgo in minente de suicidio. Se consideró como caso de riesgo suicida a un puntaje > 5 en la escala Okasha o la respuesta afirmativa a una de las preguntas de anclaje. Se calculó el valor índice con los perfiles de salud del EQ-5D-5L. Se estimaron Odds Ratios (OR's) con intervalos de confianza (IC95%), ajustando por confusores y se calcularon áreas bajo la curva ROC (AUC-ROC) para evaluar la capacidad de pesquisa del EQ-5D-5L. RESULTADOS: 21 (16,4%) adolescentes fueron considerados como casos de riesgo suicida. Controlando por confusores, las dimensiones del EQ-5D-5L que se asociaron con riesgo suicida fueron: dolor/malestar (OR: 2,5; IC95% 1,1-6,1) y ansiedad/depresión (OR: 2,2; IC95% 1,3-3,6). El AUR-ROC para ambas dimensiones fue del 0,85% (IC95% 0,75-0,91) y de 0,81% para el valor del índice del EQ-5D-5L (IC95% 0,72-0,89). CONCLUSIONES: La CVRS podría ser un factor de riesgo de suicidio en adolescentes; y el EQ-5D-5L que mide esta dimensión, podría ayudar a pesquisar futuros casos y casos ocultos de riesgo suicida.

INTRODUCTION: Health-related quality of life (HRQoL) deterioraton is a risk factor for suicide in adults, however, this aspect has been little studied in adolescents. OBJECTIVE: To evaluate the asso ciation between HRQoL (measured with EQ-5D-5L) and suicidal risk in adolescents and its capacity for cross-sectional detection of suicidal risk. PATIENTS AND METHOD: 128 adolescents (15-19 years old) from Puerto Aysen (Chile) responded to the EQ-5D-5L questionnaire, the Okasha Suicide Scale and two anchoring questions of imminent suicide risk. A suicide risk case was considered to have a > 5 score on the Okasha scale or the affirmative answer to one of the anchoring questions. The index value of EQ-5D-5L was calculated and Odds Ratios (ORs) were estimated with confidence intervals (95% CI), adjusted for confounders. Areas under the ROC curve (AUC-ROC) were calculated to assess the discriminatory performance of EQ-5D-5L. RESULTS: 21 (16.4%) adolescents were at suicidal risk. Controlling for confounders, the EQ-5D-5L dimensions associated with suicidal risk were pain/ discomfort (OR: 2.5; 95% CI 1.1-6.1) and anxiety/depression (OR: 2.2; 95% CI 1.3-3.6). The AUC- ROC for both dimensions was 85% (95% CI 0.75-0.91) and 81% for the EQ-5D-5L index value (95% CI 0.72-0.89). CONCLUSIONS: HRQoL could be a risk factor for suicide in adolescents and in this way, the EQ-5D-5L could help in searching for high risk and hidden cases of suicidal risk.

El programa RADAR para la prevención del suicidio en adolescentes de la región de Aysén, Chile: resultados preliminares / RADAR: a program for the prevention of suicide in adolescents in the region of Aysen, Chile, preliminary results

OBJETIVO: Dar a conocer los resultados preliminares del programa comunitario RADAR (Red para la Atención y Derivación de Adolescentes en Riesgo suicida). MÉTODO: Durante el 2016, RADAR fue implementado como prueba de concepto en dos colegios de Puerto Aysén de la Región de Aysén, Chile. Se capacitó un total de 409 participantes (entre alumnos, profesores de los colegios, apoderados y profesionales de la salud) para la pesquisa y derivación de adolescentes en riego de suicidio. RESULTADOS: De un total de 144 alumnos que pasaron los sistemas de pesquisa de RADAR, se detectaron 29 casos en riesgo suicida (20%) y 27 fueron derivados oportunamente al Servicio de Urgencia del Hos pital de Puerto Aysén. En la segunda campaña de pesquisa de RADAR, 3 meses después, el 90% de los casos ya no presentaba riesgo suicida. CONCLUSIÓN: Estos resultados muestran la alta proporción de adolescentes en riesgo suicida que no son visibilizados por el sistema de salud y la factibilidad de implementar RADAR en la comunidad como una intervención preventiva efectiva.

OBJECTIVE: We present the preliminary results of the implementation of RADAR: a community suicide prevention program in adolescents implemented in two high schools in a south region of Chile. METHOD: In a pilot study, during 2016, we implemented RADAR in two high schools of Puerto Aysen, in in the Region of Aysen of Chile. A total of 409 actors were trained (among students, school teachers, caregivers and health professionals) for the screening and referral of high suicide risk adolescents. RESULTS: Out of a total of 144 students who passed the RADAR screening systems, 29 cases were detected as suicide risk (20%) and 27 of them were opportunely referred to the Emergency Service of the Hospital of Puerto Aysen. In the second RADAR screening campaign, 3 months later, 90% of the cases no longer presented suicide risk. CONCLUSION: These results show the high proportion of ado lescents at risk of suicide who are not visible by the health system and the feasibility of implementing RADAR in the community as an effective suicide prevention intervention.

Sensibilidad al cambio de la versión español-chileno del cuestionario International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) para incontinencia urinaria femenina / Responsiveness of the chilean version of the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF)

Background: A symptom questionnaire must be able to detect minimal changes after treatment to be clinically useful. Aim: To evaluate the responsiveness of the Spanish-Chilean version of the ICIQ-SF questionnaire after medical and surgical procedures for the treatment of urinary incontinence (UI) in women consulting at a public Chilean Hospital. Material and Methods: Data of 124 women aged 59 ± 10 years who were treated for UI and in whom ICIQ-SF questionnaire was applied in two opportunities (before and after medical or surgical treatment), was analyzed. The sign test for paired samples was used to compare the response of each item of the questionnaire. Responsiveness of the total severity score for UI was assessed by changes of slopes estimated by Generalized Estimating Equations. Slopes of change for every type of treatment were also compared. Results: Sixty two percent of the women underwent surgical treatment. The slope of the total severity score for medical treatment was -4.4 (p-value < 0.001 for change) and 12.6 (p-value < 0.001 for change) for surgical treatment. Changes in surgical treatment were significantly higher than those of medical treatment (p-value < 0.001). Conclusions: The Spanish-Chilean version of the ICIQ-SF questionnaire was able to detect changes as a result of surgical and medical treatment for urinary incontinence in the study population, fulfilling the validity of responsiveness criterion.

Tendencia de la tasa global de fecundidad y el aumento de la fuerza laboral femenina en Chile. 1960-2011 / Association between the decline in global fertility rate and the incorporation of women to the workforce

Background: The global fertility rate (GFR) is defined as the mean number of children that a woman could have in a hypothetical cohort, not exposed to death during the fertile period. GFR has fallen from 3.4 to 1.9 children per women in the period 1970-2010. Aim: To explore the relationship between the fall in GFR and the incorporation of women to work in the period 1960-2011. Material and Methods: Data from the National Statistics Institute was used. GRF was calculated using specific fertility rates for each year considering women aged 15 to 49 years. Work rates were obtained from yearly vital statistics reports. Results: Between 1960 and 2011, GRF decreased from 5.5 to 1.9 in Chile. The first inflection occurred in 1970. In the same period, female workforce increased from 22.4 to 40.2%. Conclusions: To motivate the participation of female work­force without decrease the GRF allowing population replacement, it is suggested the need to create new public policies with benefits and support from the state.

Cambios del estado clínico periodontal según consumo sistémico de estatinas / Changes in clinic periodontal status according to systemic statins intake

Objetivos: Describir los cambios del estado clínico periodontal de pacientes según el consumo sistémico de estatinas por indicación del cardiólogo. Material y método Se realizó un estudio descriptivo en el cual se reclutaron pacientes con periodontitis crónica derivados desde cardiología de la Clínica Dávila. Un grupo de ellos iniciaría terapia de estatinas. Se realizaron mediciones clínicas periodontales de profundidad al sondaje (PS), nivel de inserción clínico, índice de sangrado, área de superficie periodontal inflamada, e índice gingival, al inicio (antes de comenzar la terapia de estatinas) y 6 meses después. Los datos fueron analizados utilizando estadística descriptiva. Resultados Diez pacientes participaron del estudio, 5 con indicación de estatinas. El grupo con estatinas en comparación con el grupo sin estatinas presentó una disminución en promedio: de PS (0,4 mm versus 0,13 mm); porcentaje de sitios con PS > 5 mm (4,16 por ciento versus 1,09 por ciento); de nivel de inserción clínico (0,5 mm versus 0,2 mm), índice de sangrado (27,16 por ciento versus 8,8 por ciento) y área de superficie periodontal inflamada (305,68 mm2 versus 121,35). Conclusiones Estos resultados sugieren que pacientes con periodontitis crónica podrían obtener beneficios de la terapia sistémica con estatinas. Se requiere de estudios clínicos con asignación aleatoria y el óptimo tamaño muestral que comprueben el efecto e impacto de las estatinas sobre el estado periodontal.

Objective: To describe changes in periodontal clinical status of patients according to systemic statin use prescribed by a cardiologist. Material and methods A descriptive study was performed on patients with chronic periodontitis referred from the Department of Cardiovascular Diseases of Dávila Clinic. A group of them began statin therapy. Clinical measurements of periodontal probing depth (PD), clinical attachment level, bleeding index, periodontal inflamed surface area, and gingival index, were performed at baseline (before starting statin therapy) and 6 months later. Data were analyzed using descriptive statistics. Results A total of 10 patients participated in the study, and five of them received statin therapy. The statin group compared to the group without statins, showed a mean decrease in: PD (0.4 mm versus 0.13 mm); percentage of PS sites > 5 mm (4.16 percent versus 1.09 percent); clinical attachment level (0.5 mm versus 0.2 mm), bleeding index (27.16 percent versus 8.8 percent), and periodontal inflamed surface area (305.68 versus 121.35 mm2). Conclusions These results suggest that patients with chronic periodontitis may benefit from systemic therapy with statins. Randomized clinical trials with optimal sample size are required to check the effect and impact of statins on the periodontal status.

Intereses y perspectiva sobre la carrera de medicina: un contraste entre estudiantes de medicina de primero y séptimo año / Interests and perspectives of first and last year medical students

Background: The interests that motivate medical students to study this career are diverse and they may change during the seven years of study. In Chile, 22 universities offer medicine and the number of graduated students has increased by more than 50% over the last 10 years. Aim: To determine the motivational profile of medical students at admission, and at the end of their career. Subjects and Methods: A voluntary anonymous survey was applied to 275 first and 140 seventh year medical students from one traditional public and two private schools. Results: The main reason for applying to medical school was social interest (68.7%), followed by interest in science and academia. Thirty six percent of students from seventh year would not study medicine again. In the seventh year, the interest in medical care persists in 88% of students, followed by academic interests in 64%. Only 24% had research interests. Fifty nine and 57% of students projected their medical work in private and public hospital settings, respectively. Only 11% projected themselves as doing research. Sixty nine percent of students would like to receive more information about post graduate education. Conclusions: There is a low interest in research and a high percentage of seventh year students that would not apply to medicine again. Medical schools should perform a systematic analysis of students' interests to improve faulty areas.
