La Atención Primaria en Salud, un camino inconcluso en Colombia: Lecciones aprendidas de la Primera Ola de la Pandemia por COVID-19 / Primary Health Care, an unfinished road in Colombia: Lessons learned from the First Wave of the COVID-19 Pandemic

RESUMEN Introducción: En 2020, Colombia adoptó diferentes medidas para mitigar el impacto de la pandemia por Covid-19, principalmente medidas de aislamiento social y fortalecimiento en la prestación de servicios hospitalarios. Sin embargo, el país no contempló acciones para abordar los otros problemas en salud, como tampoco consideró la relevancia de la Atención Primaria en Salud (APS) para responder a la pandemia. Por lo cual se realizó una investigación para indagar por la oferta y posicionamiento de la APS entre los tomadores de decisiones para atender la emergencia de Covid-19 durante la primera ola de la pandemia y los aprendizajes para las siguientes. Metodología: De abril a junio de 2020 se realizó un estudio descriptivo exploratorio mixto en 2 fases: (1) Encuesta a tomadores de decisiones, prestadores y académicos, y (2) Grupo focal a informantes clave. Resultados: La encuesta fue respondida por 227 participantes, 41 % académicos, 34.8 % prestadores y 17.6 % funcionarios de direcciones locales de salud; el 28.2 % consideró que la APS estuvo adaptada en los territorios para diferentes programas de salud por ciclo vital y entre el 80 al 98 % que la APS debía instaurarse en el territorio para vigilancia de casos, atención ambulatoria, manejo de pacientes crónicos, atención de otros programas y educación sanitaria. En el grupo focal participaron 12 informantes claves, quienes concluyeron que desde la autoridad sanitaria se debía promover la integración de la APS de forma urgente en los territorios, y garantizar una gobernanza eficaz para lograrlo; igualmente, recomendaron intensificar la alfabetización en salud y el empoderamiento de la población para la adopción de medidas individuales y colectivas. Conclusiones: Se concluye que la APS era una oportunidad para responder a la primera ola de la pandemia, como también para subsanar los problemas actuales y anticiparse a problemas futuros. Por lo cual, la APS debe convertirse en una política de Estado.

ABSTRACT Introduction: In 2020, Colombia adopted different measures to mitigate the impact of the Covid-19 pandemic, social isolation measures and strengthening the provision of hospital services. However, the country did not contemplate actions to address other health problems, nor did it consider the relevance of Primary Health Care (PHC) to respond to the pandemic. Therefore, an investigation was done to investigate the offer and positioning of PHC among decision-makers to address the Covid-19 emergency during the first wave of the pandemic and the learning for the following ones. Methodology: From April to June 2020, a mixed exploratory descriptive study was conducted in two phases: (1) a survey of decision-makers, providers, and academics, and (2) a focus group of key informants. Results: The survey was answered by 227 participants, 41 % academics, 34.8 % providers, and 17.6 % officials from local health directorates; 28.2 % considered that PHC was adapted in the territories for different life cycle health programs, and between 80 and 98 % that PHC should be established in the territory for case surveillance, outpatient care, management of chronic patients, care of other programs and health education. Twelve key informants participated in the focus group, who concluded that the health authority should urgently promote the integration of PHC in the territories, and guarantee effective governance to achieve it; Likewise, they recommended intensifying health literacy and the empowerment of the population for the adoption of individual and collective measures. Conclusions: It is concluded that PHC was an opportunity to respond to the first wave of the pandemic, as well as to correct current problems and anticipate future problems. Therefore, PHC must become a state policy.

Conclusions: The incorporation of the pandemic cinema genre, accompanied by the observation-relation-application strategy, the use of a perceptions and beliefs questionnaire, as well as other elements, improves the teaching-learning process, favors the approach to complex thinking problems, and improves empathy between professors and students in the classroom(AU)

Determinantes sociales de salud y su relación con desnutrición infantil en dos comunidades étnicas colombianas / Social determinants and malnutrition of infants from two Colombian indigenous communities

RESUMEN Objetivo Identificar la relación entre los determinantes sociales de la salud y el estado nutricional de los niños pertenecientes a dos comunidades indígenas de la Costa Caribe colombiana, los wayús y los zenús. Métodos Estudio transversal que aborda el estado nutricional de los wayús y los zenús en edad preescolar y escolar. Incluyendo, además, estimación de determinantes sociales de la salud, referida por cuidadores de menores, que aborda algunos aspectos de ejes de desigualdad de tipo estructural (etnia, territorio, edad y sexo) e intermedios: vivienda, entorno y redes, mediante instrumentos de salud familiar. Se estandarizaron métricas de talla, peso e insumos de familiograma y ecomapa. Se estimaron medidas descriptivas de tipo frecuentistas y de medidas de tendencia central. Se estimó la odds ratio y su relación con variables independientes. Resultados La prevalencia de desnutrición global en la etnia Wayú fue del 59,1% IC (47,569,8) y en la etnia Zenú del 22,4% IC (15,9-30,4) para una p<0,001. Esta diferencia se relaciona con factores de riesgo intermediarios de saneamiento: inadecuadas excretas con OR=2.54; IC (1.42-4.53) p=0.002, la falta de empleo OR=1.94; IC (1.09-3.46) P=0.03 y falta de acceso a servicios de salud occidental OR=2.42; IC (1.34-4.40) p=0.005. Conclusiones La mejora en la nutrición requiere intervenir determinantes intermedios relacionados con saneamiento, modelo de salud, intersectorialidad de políticas en salud más enfoque étnico-cultural y territorial.

ABSTRACT Objetive To identify the relationship between the Health's Social Determinants and the nutritional status of children belonging to two indigenous communities on the Colombian Caribbean coast, the Wayú and the Zenú. Methods Cross-sectional study that addresses nutritional status in wayúes and zenúes at preschool and school age. Also including the estimation of health's social determinants, referred by minor's caregivers, which addresses some aspects of structural ¡nequality axes (ethnicity, territory, age, and sex) and intermediates: housing, environment, and networks, through health instruments family. Metrics for height, weight, and inputs for the familiogram and ecomap were standardized. Descriptive measures of frequencies and central tendency were estimated. Odds ratio and its relationship with ¡ndependent variables were estimated. Results The prevalence of global malnutrition in the Wayú ethnic group was 59.1% (47.5-69.8) and in the Zenú ethnic group 22.4% (15.9-30.4) for a p<0.001. This difference is related to intermedíate risk factors with sanitation: inadequate excreta with OR=2.54; CI (1.42-4.53) p=0.002, lack of employment OR=1.94; CI (1.09-3.46) P=0.03 and lack of access to western health services OR=2.42; IC (1.34-4.40) p=0.005. Conclusions Improvement in nutrition requires the intervention of intermediate determinants related to sanitation, health model, intersectoriality of health policies plus an ethnic-cultural and territorial focus.

Una mirada histórico-geográfica de las pandemias: para entender de manera compleja la COVID-19 / A Historical-Geographical View of Pandemics: to Understand COVID-19 in a Complex Way

RESUMEN El abordaje para la investigación de brotes/pandemias es una actividad desafiante, necesaria y retadora para los salubristas y epidemiólogos. Esta actuación permite que los servicios de epidemiología y de vigilancia profundicen el conocimiento de la enfermedad, recaben datos históricos de episodios pandémicos, caractericen vulnerables, planteen hipótesis e intervengan los factores de riesgos en un contexto ambiental y sociocultural determinado con una actuación local y una perspectiva global. Se considera un abordaje sindémico, de tal manera que conjugan aspectos de determinantes sociales interconectados y profundizando en la pandemia.

ABSTRACT The outbreak/pandemic investigation approach is a challenging, necessary and challenging activity for health professionals and epidemiologists. This approach allows epidemiology and surveillance services to deepen their knowledge of the disease, collect historical data on pandemic episodes, characterize vulnerabilities, develop hypotheses and intervene risk factors in a given environmental and sociocultural context with local action and a global perspective. A syndemic approach is considered, in such such a way that it combines aspects of interconnected social determinants and deepening in the pandemic.

Estudo descritivo transversal; 211 mulheres com câncer de mama participaram através de uma pesquisa estruturada. Foi encontrada uma associação estatística entre a prática do auto-exame das mamas e o fato de ter uma educação superior e pertencer ao nível contributivo; além disso, uma mulher com menos de 50 anos de idade com diagnóstico confirmado de câncer e com um nível de educação superior entrou com uma ação de tutela. São identificadas as lacunas derivadas da estratificação social, segmentação geográfica e acesso a mecanismos de informação telefônica. Portanto, as condições de vulnerabilidade, baixo nível educacional e pobreza marcam diferenças e denotam a perda de oportunidades de detecção, cuidado e tratamento.

To identify factors related to knowledge of the current state of the disease in women with breast cancer and sociodemographic factors, diagnosis, treatment and care of breast cancer in oncological institutions, Cartagena-Colombia. Cross-sectional descriptive study; 211 women with breast cancer participated through a structured survey. A statistical association was found between the practices of breast self-examination and having a higher education and belonging to the contributory level; in addition, a woman under 50 years old with a confirmed diagnosis of cancer and with a higher education level uses guardianship action by right. Gaps derived from social stratification, geographical, health system segmentation and access to telephone information mechanisms are identified. Therefore, the conditions of vulnerability, low educational level and poverty mark differences and denote lost opportunities for detection, care and treatment.

COVID-19 en la Región Caribe Colombiana: un análisis documental / Covid19 in the Colombian Caribbean Region: A Documentary analysis

Resumen Introducción: El impacto social y sanitario que ha generado la pandemia COVID-19 a nivel global permite repensar aspectos de vigilancia epidemiológica y comunicación en tiempos de crisis. Objetivo: Describir el comportamiento de la pandemia COVID-19 en los departamentos y distritos especiales de la región caribe colombiana. Materiales y Métodos: Análisis documental e interpretativo a partir de fuentes secundarias de vigilancia nacional "SIVIGILA" y datos de entes territoriales. Resultados: Cartagena de Indias es la primera unidad territorial del Caribe en presentar casos por COVID-19, seguido de Santa Marta y Barranquilla. El mayor número de casos se registró en Barranquilla, Atlántico, Cartagena y Córdoba. Así mismo, la mayor tasa de muertes por 100 000 habitantes se registró en Barranquilla, Atlántico, Córdoba, Santa Marta, Sucre y Cartagena. En el Caribe se implementaron estrategias de distanciamiento social como prohibición de eventos masivos y cierre de fronteras. Discusión: Para describir el comportamiento de la pandemia es importante que las autoridades sanitarias continúen asumiendo el reto para la detección, sistematización y manejo oportuno de los casos. El comportamiento de la pandemia ha sido similar en los departamentos del Caribe Colombiano, hay una homogeneidad al momento de acatar las normas del gobierno, y cada región adaptó diferentes estrategias dentro de un marco general para reducir la incidencia de la enfermedad. Se recomienda fortalecer la similitud entre los datos reportados por el Ministerio de Salud, SIVIGILA y los entes territoriales. El talento humano en salud cualificado puede soportar este ejercicio a fin de superar la actuación mediática y avanzar hacia la gobernanza.

Abstract Background: The social and health impact generated by the COVID-19 pandemic allows us to re-think aspects of epidemiological surveillance and communication in struggle-times. Objective: To describe the behavior of the COVID-19 pandemic in the departments and special districts of the Colombian Caribbean region. Methodology: This is a documentary and interpretive analysis from secondary sources of National Surveillance "SIVIGILA" and data from local governments. Results: Cartagena de Indias is the first territorial area in the Caribbean to present cases COVID-19, followed by Santa Marta and Barranquilla. The highest number of cases was registered in Barranquilla, Atlántico, Cartagena and Córdoba. Likewise, the highest death rate per 100,000 inhabitants was observed in Barranquilla, Atlántico, Córdoba, Santa Marta, Sucre and Cartagena. In the Caribbean, social distancing was implemented, as well as the limitation of mass gatherings and border closure. Discussion: To describe the pandemic behavior, it is important that health authorities continue to assume the challenges of detection, systematization, and timely handling of cases. The COVID-19 performance has been similar in the Colombian Caribbean. There is a homogeneity regarding the government regulations compliance and each region adapted different strategies to reduce the incidence of the dicease. It is recommended to strengthen the concordance between the data reported by the Ministry of Health, SIVIGILA, and the territorial entities. Qualified human talent can support this exercise in order to overcome the media performance through the strengthening of governance.

Polimorfismos de los genes del sistema leptina-melanocortina asociados con la obesidad en la población adulta de Barranquilla / Polymorphisms of leptin-melanocortin system genes associated with obesity in an adult population from Barranquilla

Introducción. La obesidad se considera un grave problema de salud pública y por ello se hacen esfuerzos en la búsqueda de genes como el LEP, el LEPR y el MC4R del sistema leptina-melanocortina, el cual opera en la regulación neuroendocrina de la ingestión y el equilibrio energético e influye en la patogenia de la enfermedad. Los resultados contradictorios en torno a la asociación de estos genes con la obesidad plantean la necesidad de nuevas investigaciones. Objetivo. Analizar los polimorfismos rs2167270 del gen LEP, rs1137101 del gen LEPR y rs17782313 del gen MC4R asociados con la obesidad y sus variables clínicas y bioquímicas en una muestra de pacientes adultos de Barranquilla. Materiales y métodos. Se estudiaron 111 personas obesas y 155 no obesas como controles. Los polimorfismos se determinaron mediante reacción en cadena de la polimerasa (PCR) en tiempo real. Se tomaron las medidas antropométricas, se evaluó la presión arterial y se hicieron pruebas bioquímicas. Resultados. No se encontraron diferencias estadísticas en la frecuencia alélica y genotípica de los polimorfismos en los grupos estudiados. En cuanto a las variables clínicas y bioquímicas, el genotipo CC del polimorfismo rs17782313 del gen MC4R, se asoció con un aumento de la presión arterial sistólica y, el alelo T y su genotipo homocigoto, con una disminución del colesterol HDL en los obesos. No se evidenció ningún efecto de los otros polimorfismos en estas variables. Conclusiones. Los polimorfismos rs2167270 del gen LEP, rs1137101 del gen LEPR y rs17782313 del gen MC4R, no se asociaron con obesidad en la población analizada. Se encontró que el polimorfismo rs17782313 del gen MC4R influyó en el aumento de la presión arterial sistólica y la disminución del colesterol HDL en las personas obesas.

Introduction: Obesity is considered a serious public health problem. Efforts have been directed to search for candidate genes such as LEP, LEPR, and MC4R involved in the leptin- melanocortin system. The neuroendocrine regulation of these genes on energy intake and balance influences the pathogenesis of this disease. Contradictory results regarding the association of these genes with obesity raise the need for new research. Objective: To analyze the association between obesity and LEP rs2167270, LEPR rs1137101, and MC4R rs17782313 polymorphisms and the clinical and biochemical variables in obese adults from Barranquilla, Colombia. Materials and methods: We analyzed 111 obese adults and 155 non-obese individuals as controls. The polymorphisms were determined by real-time PCR. Besides, anthropometric measures, blood pressure, and biochemical tests were evaluated. Results: No statistical differences were found in allele and genotype frequencies of gene polymorphisms between groups. The CC genotype of MC4R rs17782313 polymorphism was associated with increased systolic blood pressure and T allele and TT genotype, with decreased HDL cholesterol in obese adults. The effect of the other polymorphisms on these variables was not evidenced. Conclusions: LEP rs2167270, LEPR rs1137101, and MC4R rs17782313 polymorphisms were not associated with obesity in the population under study. MC4R rs17782313 polymorphisms were associated with an increase in systolic blood pressure and a decrease in HDL cholesterol.

Cardiometabolic risk factors associated with renal function in apparently healthy young students: a cross-sectional study

ABSTRACT Background: Cardiometabolic risk factors (CMRFs) appear decades before developing chronic kidney disease (CKD) in adulthood. Objective: The objective of the study was to identify the prevalence and association between CMRFs and kidney function in apparently healthy young adults (18-25 years old). Methods: We included 5531 freshman year students. Data collected on CMRFs included central obesity, high body mass index (hBMI >25), blood pressure, glycemia, lipids, uric acid (UA >6.8 mg/dL), and insulin. Glomerular filtration rate (GFR) was estimated by CKD-Epidemiology Collaboration formula. We used logistic regression and a log linear for odds ratio (OR) (95% confidence level) and probabilities. Results: The presence of any CMRF was observed in 78% (4312) of individuals; GFR ≥120/130 mL/min/1.73 m2sc was found in 33%, GFR <90 mL/min/1.73 m2sc in 3%, and proteinuria in 3%. Factors associated with high GFR were hBMI (OR 1.3 [1.14, 1.47]), UA (OR 0.2 [0.15, 0.26]), high-density lipoprotein (HDL) (OR 1.4 [1.2, 1.6]), and insulin resistance (OR 1.3 [1.05, 1.7]). CMRF associated with low GFR was UA (OR 1.8 [1.3, 2.6]), low-density lipoprotein cholesterol (OR 1.66 [1.05, 2.6]), and proteinuria (OR 3.4 [2.07, 5.7]). Proteinuria was associated with high UA (OR 1.59 [1.01, 2.5]) and hypercholesterolemia (OR 1.8 [1.03, 3.18]). The sole presence of hBMI+UA predicted low GFR with p = 0.6 and hBMI+UA+low HDL predicted proteinuria with p = 0.55. Conclusions: CMRFs were highly prevalent among this freshman student population and were associated with proteinuria and GFR abnormalities. Future studies should focus on public health programs to prevent or delay the development of CKD.

Percepciones y creencias al uso de película comercial tipo epidemia/pandemia en el aula: Insumos para orientar el aprendizaje / Perceptions and beliefs to the use of epidemic / pandemic commercial film in the classroom: Inputs to guide learning

RESUMÉN Objetivo: Valorar el uso de la película comercial "Contagión" como estrategia para la enseñanza del método epidemiológico aplicado al campo de epidemias/pandemias. Materiales y métodos: Se trata de un proyecto de aula que involucró diversas tecnologías emergentes y de comunicación para disponer de herramientas atractivas y pedagógicas que favorezcan aprendizaje significativo para abordaje de temáticas complejas. La actuación pedagógica involucró diversos insumos: inicialmente se presenta la caracterización de un cuestionario "ah doc" que valoró creencias y percepciones ante una epidemia/pandemia y cómo visibilizaban entes de salud locales e internacionales, los científicos, la comunidad y el uso de película en el escenario de aprendizaje. Participaron 131 estudiantes. Resultados: En síntesis, los estudiantes identifican que este tipo de película muestra una realidad para el 70,2% (acuerdo y totalmente de acuerdo),favorece conductas de protección en un 80,2 % y al 78,6 % le modifica su conocimiento con respecto a la protección de salud. Favorece un aprendizaje en el aula, y para el 42 % se expresa de manera indiferente un estereotipo muy alejado de los científicos. Con este insumo inicial se desarrolló la sesión introductoria de abordaje de puntos críticos en la metodología epidemiológica ante una epidemia/pandemia; lo que permitió ilustrar la acción epidemiológica versus el contexto real o simulado, destacando actuaciones que involucran actos humanos. Conclusiones: Los estudiantes expresaron actitud positiva respecto a la estrategia utilizada en el aula, que se constituye en un insumo pertinente, activo, crítico y eficaz para el aprendizaje en el aula.

ABSTRACT Objective: To assess the use of commercial film "Contagion" as a strategy for teaching the epidemiological method applied to the field of epidemics/pandemics. Materials and methods: This is a classroom project that involved various emerging and communication technologies in order to have attractive and pedagogical tools that encourage meaningful learning to address complex issues. The pedagogical action involved several inputs: Initially, the characterization of an "ah doc." questionnaire was presented, which evaluated beliefs and perceptions in the face of an epidemic/pandemic and how local and international health entities, scientists, the community and the use of film in the learning scenario made them visible, with 131 students participating. Results: In summary, students identified that this type of film shows a reality "in agreement and total agreement in 70.2 %, favors protective behavior in 80.2 % and 78.6 % modify their knowledge with respect to health protection. This positions that it favors a learning in the classroom and for 42 % it expresses in an indifferent way a stereotype very far from the scientists. With this initial input, the introductory session was held to address critical points in the epidemiological methodology in the face of an epidemic/pandemic, which made it possible to illustrate the epidemiological action versus the real or simulated context by highlighting actions involving human acts. Conclusions: Students expressed a positive attitude towards the strategy used in the classroom, which constitutes a relevant, active, critical and effective input for classroom learning.

Diabetes gestacional: implementación de una guía para su detección en la atención primaria de salud / Implementation of a clinical guideline for detection of gestational diabetes in primary care

Background: Gestational diabetes (GD) impacts maternal and fetal morbidity. In 2012, the World Diabetes Foundation provided financing project in Barranquilla (Colombia), aimed to implement a clinical guide for the diagnosis and treatment of this condition. Aim: To estimate the adherence of the guide in primary care centers. Material and Methods: A Cross-sectional study of pregnant women suspected of having gestational diabetes. Pregnant women were classified according to the week of admission to the prenatal control program: < week 24 or later. Women with a fasting blood glucose over 92 mg/dL and under 126 mg/dL or with some positive result to the oral glucose tolerance test were included. Results: Nine percent (1,887 women) of 21,699 registries of pregnant women, were at risk for gestational diabetes. Of these, 1,880 registries with complete data were analyzed. Sixty nine entered the program at less than 24 weeks of pregnancy and 71% had had a fasting blood glucose measured in the first control. In 69.2% of these women, criteria for gestational diabetes was met. A glucose tolerance test was suggested to women with a blood glucose below 92 mg/dl. Among 72% of the latter, the glucose tolerance test met the criteria for gestational diabetes. Among the 498 women who entered the program after 24 weeks of gestation, 68% met the criteria for gestational diabetes with the fasting blood glucose levels. In 90 women, a glucose tolerance test was performed and 80% met the criteria for gestational diabetes. Conclusions: An adequate adherence to guidelines favors the detection of pregnant women with gestational diabetes.

Seroprevalencia en una zona de hiperendemia por dengue, Barranquilla, Colombia / Sero-Prevalence in a Hyperendemic Area of Dengue: Barranquilla-Colombia / Soroprevalência numa área de hiperendemia por dengue, Barranquilla-Colômbia

RESUMEN Objetivo: Estimar seroprevalencia de anticuerpos IgG e IgM para dengue y factores asociados. Método: estudio transversal, mediante la aplicación de encuesta y estimación serológica para IgG e IgM para dengue en mayores de 15 años con representabilidad por localidad y sexo. 478 sujetos encuestados en la ciudad de Barranquilla Colombia Análisis estadístico, mediante el programa SPSS®, versión 22. Se estimó la sero-prevalencia para el análisis univariado y el análisis bivariado mediante la odds ratio de proporciones con una p<0,05. Resultados: la seroprevalencia para IgG fue 88,2% (IC 95% =85,2-91,1) y para IgM de 11,8% (IC 95%= 8,80-14,75). Se encontró asociación estadística en edades de 30 a 49 y 50-69 años (OR=7,09 [2,6-19,3] y OR= 8,93 [2,9-27,0] respectivamente), pertenecer al régimen de salud subsidiado (OR=2,56[1,18-5,53]) y ocupación hogar (OR= 3,38[1,31-8,67]. Conclusiones: la alta seroprevalencia para IgG es explicada por la circulación de los cuatro serotipos en el país, los brotes epidémicos cada dos a tres años y los comportamientos y prácticas desfavorables relacionadas con el manejo de agua. Se requiere cambios de conducta frente al manejo de factores predisponentes, la atención oportuna de sintomáticos y vigilancia activa comunitaria e institucional ante casos sospechosos.

ABSTRACT Objective: estimate the sero-prevalence of IgG and IgM antibodies for dengue and associated factors. Method: A cross-sectional study was done by means of a survey and serological estimation for IgG and IgM for dengue in subjects over 15 years of age with representability by location and gender. In all, 478 subjects were surveyed in the city of Barranquilla, Colombia. The SPSS® program, version 22, was used for the statistical analysis. Sero-prevalence was estimated for univariate analysis and bivariate analysis using the odds ratio of proportions with p <0.05. Results: The sero-prevalence for IgG was 88.2% (95% CI = 85.2-91.1); for IgM, it was 11.8% (95% CI = 8.80-14.75). A statistical association was found between subjects ages 30 to 49 and those ages 50 to 69 (OR = 7.09 [2.6-19.3] and OR = 8.93 [2.9-27.0] respectively) who are part of the subsidized health system (OR = 2.56 [1.18-5.53]) and list homemaker as their occupation (OR = 3.38 [1.31-8.67]). Conclusions: The high sero-prevalence for IgG is explained by circulation of the four serotypes in the country, epidemic outbreaks every two to three years, and unfavorable behavior and practices related to water management. Behavioral changes are needed when it comes to dealing with predisposing factors, timely symptomatic care and active community and institutional surveillance in response to suspected cases.

Prevalence of bullying by gender and education in a city with high violence and migration in Mexico / Prevalencia de intimidación desglosada en función del sexo y la escolaridad en una ciudad mexicana con índices altos de violencia y migración / Prevalência de bullying por gênero e escolaridade em uma cidade com altos índices de violência e migração no México

ABSTRACT Objective To understand the prevalence of bullying, by gender and educational level, in Ciudad Juárez, Mexico, a city with high rates of violence and migration. Methods This was a cross-sectional, observational study conducted in 2012 – 2014 using a questionnaire known as the Bullying-Mexican. A probabilistic multistage cluster-sampling method obtained a study sample of 2 347 students (10 – 27 years of age) from the 400 000 enrolled in grade 5 – university level at the 611 public schools in Ciudad Juárez. Bullying prevalence and frequency (never, rarely, sometimes, often, every day) were analyzed with descriptive statistics. The statistical differences between males and females was assessed using a chi-square test; associations between frequency and academic level were determined by correspondence analysis and the Spearman Rho correlation. A multinomial logistic regression was performed to analyze whether gender and academic level acted independently in the frequency of bullying. Results Bullying prevalence was reported by 38% of females and 47% of males: ‘only victim’ represented 8.7%; ‘only aggressor,’ 13.2%; and ‘victim and aggressor,’ 21%. At higher levels of education, bullying prevalence declined; however, at the university, prevalence increased in the last semesters. Mockery and social exclusion were the two most dominant types of bullying, followed by beating, threats, and punishment. Conclusions The prevalence of bullying in Ciudad Juárez public schools is among the highest compared to other random studies and surveys. Bullying diminishes with age and educational level.

RESUMEN Objetivo Comprender la prevalencia de intimidación o bullying, desglosada en función del sexo y el nivel de escolaridad, en Ciudad Juárez (México), ciudad con índices altos de violencia y migración. Métodos Este estudio transversal de observación se realizó entre el 2012 y el 2014 con el cuestionario mexicano sobre la intimidación (Bull-M). Tras aplicar el método probabilístico polietápico de muestreo por conglomerados, se obtuvo una muestra de 2 347 estudiantes (de 10 a 27 años) de los 400 000 matriculados entre el quinto grado y el nivel universitario en las 611 instituciones de educación pública de Ciudad Juárez. Se analizaron la prevalencia y la frecuencia de la intimidación (nunca, rara vez, a veces, a menudo, todos los días) mediante estadísticas descriptivas. Se evaluó la diferencia estadística entre los hombres y las mujeres con la prueba de la ji al cuadrado y se determinó la asociación entre la frecuencia y el nivel académico mediante el análisis de correspondencias y la correlación ro de Spearman (R). Se aplicó una regresión logística polinómica para analizar si el sexo y el nivel académico eran variables independientes respecto de la frecuencia de la intimidación. Resultados La intimidación tuvo una prevalencia del 38% en las mujeres y del 47% en los hombres: refirieron ser “solo víctimas” el 8,7%; “solo agresores” el 13,2%; y “víctimas y agresores” el 21%. La prevalencia de la intimidación disminuye a medida que aumenta el nivel de escolaridad, aunque se registró un incremento en los últimos semestres de la universidad. Los dos tipos más predominantes de intimidación son la burla y la exclusión social, a los que siguen la agresión física, la amenaza y el castigo. Conclusiones La prevalencia de intimidación en las instituciones de educación pública de Ciudad Juárez se encuentra entre las más altas cuando se la compara con otros estudios y encuestas de diseño aleatorizado. La intimidación disminuye a medida que avanza la edad y aumenta el nivel de escolaridad.

RESUMO Objetivo Compreender a prevalência de bullying, estratificada por gênero e escolaridade, em Ciudad Juárez, México, um município com altos índices de violência e migração. Métodos Estudo transversal observacional realizado em 2012-2014 usando o instrumento Bullying-Mexican. Utilizando um método probabilístico de amostragem multietápica por conglomerados, obteve-se uma amostra de 2 347 estudantes (10-27 anos de idade) do universo de 400 000 estudantes matriculados da 5ª série ao ensino superior nas 611 escolas públicas de Ciudad Juárez. A prevalência e frequência (nunca, raramente, às vezes, frequentemente, todos os dias) de bullying foram analisadas mediante estatísticas descritivas. A diferença estatística entre homens e mulheres foi avaliada através do teste qui-quadrado; associações entre frequência de bullying e escolaridade foram determinadas mediante análise de correspondência e coeficiente de correlação de Spearman (R). Foi realizada análise de regressão logística multinomial para determinar se gênero e escolaridade influenciaram independentemente a frequência de bullying. Resultados O bullying foi relatado por 38% das mulheres e 47% dos homens: 8,7% identificaram-se como “somente vítimas”, 13,2% como “somente agressor”, e 21% como “vítima e agressor”. Nos níveis mais altos de escolaridade, a prevalência de bullying foi menor; porém, no ensino superior, aumentou novamente nos últimos semestres. Assédio verbal e exclusão social foram os dois tipos mais comuns de bullying, seguidos de agressão física, ameaças e castigos. Conclusões A prevalência de bullying nas escolas públicas de Ciudad Juárez está entre as mais elevadas já relatadas em estudos randomizados e levantamentos. O bullying diminui conforme a idade e escolaridade aumentam.

Mechanism of Relaxant Action of Ethyl 6-amino-5-cyano-2-methyl- 4-(pyridin-4-yl)-4H-pyran-3-carboxylate Mainly Through Calcium Channel Blockade in Isolated Rat Trachea.

This study aims to investigate the mechanism of relaxant action of Ethyl 6-amino-5-cyano-2-methyl-4-(pyridin- 4-yl)- 4H-pyran-3-carboxylate (1) in in silico study and ex vivo tracheal rat rings pre-contracted with carbachol (1 µM). Compound 1 was more active than theophylline [a phosphodiesterases (PDE’s) inhibitor] used as positive control. Moreover, pretreatment with 1 significantly shifted to the right the carbachol-induced contraction and did not allow to reach the maximum effect (p< 0.001). In addition, compound 1 (96.30 µM) produces significant (100%) relaxant effect on the contraction induced by KCl (80mM), and the CaCl2-induced contraction was completely abolished by 1 as nifedipine does (a L-type calcium channel blocker), used as positive control (p< 0.001). Meanwhile, in the presence of isoproterenol (a β-adrenergic agonist), propranolol (a β-adrenergic antagonist), and K+ channel blocker 2-AP the relaxant curve was significantly modified (p< 0.05). Compound 1 was docked on an outer cavity located on the intracellular side of the human L-type calcium channel model and interacts in the following chains and residues: chain IP (G51, W52, T53, D54), IVP (R45, E50, A51, Q53, D54) and IS6 (W4, F7). In conclusion, ex vivo and in silico approaches suggest that compound 1 induces its relaxant effect mainly by calcium channel blockade, but other mechanisms like potassium channel and cAMP accumulation could be involved.

Durante la primera etapa (2013-2014) se contribuyó principalmente a formar docentes vinculados de las distintas universidades, y se encontró una mayor adherencia en profesores de salud pública. Para la segunda etapa (2014-15), el curso se ofertó para todo el país, y mejoraron los procesos académicos en relación con el proceso anterior, y el proceso finalizó con 55 propuestas de mejoramiento en APS y RISS para cada uno de los contextos de cada participante. Conclusiones: El proceso educativo del curso y el trabajo en el CVSP se constituyen en una oportunidad para avanzar en nuevos procesos, los cuales contribuyen efectivamente a la formación de THS en APS y RISS en un país donde la temática es relevante y necesaria.

Objective: Illustrate the training experience in Health Human Resources (HHR) in PHC and IHSDNs for Colombia through the Virtual Campus of Public Health (VCPH) of the PAHO during 2013 to 2015. Methodology: an assessment of academic processes of 2 cohorts was conducted during 2013 and 2015 through VCPH, and by a team of five universities. The experience is divided into two stages according to the processes of formation: 1. Strengthening teaching equipment, 2. Training of HHR for the country. Results: In total, 123 health professionals were trained in the two processes (2013-2015). The first stage (2013-2014) was mainly linked to training teachers of different universities, process with a better performance on public health teachers. For the second stage (2014-2015) the course was offered for the entire country, improving the academic processes in relation to the above process, and ending the process with 55 proposals to improve PHC and IHSDNs for the contexts of each participant. Conclusions: The educational process of the course and work in the VCPH are constituted as an opportunity to advance new processes which effectively contribute to the formation of HHR in PCH and IHSDNs in a country where the subject is relevant and necessary.

Factores sociodemográficos y motivacionales asociados a la actividad física en estudiantes universitarios / Levels of physical activity among colombian university students

Background: Physical inactivity is an important risk factor for chronic diseases in Western societies. Aim: To determine the sociodemographic and motivational factors associated with physical activity in college students. Material and Methods: The International Physical Activity Questionnaire (IPAQ) -short form- and the “motives for physical activities measure-revised” (MPAM-R) questionnaire were applied to 900 university students aged 20 ± 3 years (60% women). The frequency, level and motivations for engaging in physical activity and associated demographic factors were analyzed. Results: Twenty two percent of students were classified as having a high level of physical activity, 54.8% had a low level and 13.9% were considered inactive. According to MET consumption, 68.9% of students are inactive and only 16.8% of students classified as very active. Ninety two percent of active students performed physical activity for health reasons. A significant association between gender and social motivation was observed. Conclusions: A high prevalence of physical inactivity was found in these students. Males showed higher levels of physical activity than females.

Desigualdades y características sociodemográficas de la mortalidad materna en La Guajira, Colombia, 2010-2012 / Inequalities and sociodemographic characteristics of maternal mortality in La Guajira, Colombia, 2010-2012

OBJETIVO: Identificar las desigualdades y las características sociodemográficas que inciden negativamente en la mortalidad materna en el departamento de La Guajira, Colombia. MÉTODOS: Se realizó un estudio descriptivo, en el que se analizaron los casos de muerte materna ocurridos en el departamento de La Guajira entre 2010 y 2012, a partir de datos de fuentes secundarias. Se calculó la diferencia de las tasas, la razón de las tasas y el riesgo atribuible poblacional porcentual, además de los índices de Gini y de concentración. RESULTADOS: Se registraron 54 muertes maternas, de ellas, 61,1% eran indígenas y 16,7% afrocolombianas; la mayoría no tenía ningún estudio (33,3%) o solo estudios primarios (29,6%). Se encontraron desigualdades en la diferencia de las tasas, la razón de las tasas y el riesgo atribuible poblacional porcentual, entre La Guajira y otros departamentos de la región Caribe y del país; sin embargo, esas diferencias no se reflejaron en los índices de Gini y de concentración. CONCLUSIONES: La mortalidad materna fue significativamente más elevada en las mujeres indígenas en comparación con las no indígenas. Se deben fortalecer los programas de salud sexual y reproductiva y adelantar dentro de las políticas de salud materna un enfoque multicultural para eliminar o reducir las desigualdades relacionadas con la mortalidad materna en esta población.

OBJECTIVE: Identify the inequalities and sociodemographic characteristics that negatively affect maternal mortality in the department of La Guajira, Colombia. METHODS: A descriptive study was conducted in which cases of maternal deaths in the department of La Guajira between 2010 and 2012 were analyzed, based on data from secondary sources. The difference in rates, rate ratio, population attributable risk percent, and Gini and concentration coefficients were calculated. RESULTS: 54 maternal deaths were recorded, 61.1% of which were indigenous and 16.7% Afro-Colombians; the majority did not have any schooling (33.3%) or only primary schooling (29.6%). Inequalities in the difference of rates, rate ratio, and population attributable risk percent were calculated for La Guajira and other departments in the Caribbean region and in Colombia; however, the differences were not reflected in the Gini and concentration coefficients. CONCLUSIONS: Maternal mortality was significantly higher in indigenous women than in non-indigenous women. Sexual and reproductive health programs should be strengthened and maternal health policies improved through a multicultural approach to eliminate or reduce inequalities related to maternal mortality in this population.
