Supervivencia global y libre de enfermedad en mujeres con sobrepeso/obesidad al diagnóstico de cáncer de mama: Un estudio observa-cional de centro único / Overall and disease-free survival in women being over-weight/obesityat the diagnosis of breast cancer. A single-center observationalstudy

Introducción:El objetivo del presente estudio fue evaluar las características clínicas, patológi-cas e histológicas tumorales y su asociación con la recurrencia, metástasis y pronóstico en términos de supervivencia global y libre de enfermedad, de las pacientes que padecen sobre-peso u obesidad al momento del diagnóstico de cáncer de mama.Materiales y métodos:Se condujo un estudio descriptivo,longitudinal,retrospectivo, en un centro oncológico de referencia de Medellín. Se recolectó información de pacientes mayores de 18 años, con cáncer de mama infiltrante temprano y avanzado, entre los años 2012 ­2017, quienes presentaran IMC ≥ 25 kg/m2 al momento del diagnóstico. Las medianas de supervi-vencia se calcularon a través de curvas de Kaplan Meier y las diferencias mediante Log Rank Test.Resultados:Se analizó información de 1.349 pacientes. La mortalidad por todas las causas fue de 13.6% y aumentó proporcionalmente con el IMC (HR = 1.03, IC 1.0-1.05). Se identifica-ron 12.6% de recurrencias y el riesgo con el aumento de IMC no fue estadísticamente signifi-cativo (HR =1.02, IC 0.99 -1.05). Características como mala diferenciación tumoral, invasión linfovascular y estadio tumoral se asociaron de forma univariada con mayor mortalidad.Conclusión:Se demostró una asociación positiva e independiente entre el IMC elevado, la mortalidad y el riesgo de recurrencia en pacientes con cáncer de mama. Así como una aso-ciación con fenotipos tumorales agresivos y características de peor pronóstico. Se sugiere considerar modificaciones en el estilo de vida y un manejo multidisciplinario, como estrate-gias que posiblemente impacten en estos desenlaces

Introduction:The objective of the present study was to evaluate the clinical, pathological, and histological characteristics of tumors and their associations with recurrence, metastasis,and prognosis in terms of overall and disease-free survival inoverweight or obese patients at the time of diagnosis.Materials and methods: A descriptive, longitudinal, retrospective study was conducted at a reference cancer center in Medellin. Information was collected from patients older than 18 years of age with early or advanced infiltrating breast cancer between 2012 and 2017 who had a BMI ≥ 25 kg/m2 at the time of diagnosis. Median survival rates were calculated using Kaplan­Meier curves, and differences were determined using the log-rank test.Results: Information from 1,349 patients was analyzed. All-cause mortality was 13.6% and increased proportionally with BMI (HR = 1.03, CI 1.0-1.05). A total of 12.6% of the recurrences were identified,and the risk with increasing BMI was not significantly different(HR =1.02, CI 0.99 -1.05). Patient characteristicssuch as poor tumor differentiation, lymphovascular inva-sion, and tumor stage were univariately associated with increasedmortality.Conclusion: Positiveand independent associations weredemonstrated between high BMI and mortality and between high BMI and the risk of recurrence in patients with breast cancer. In addition, there wasan association betweenaggressive tumor phenotypes and worse prog-nostic characteristics. Lifestylemodifications and multidisciplinary management should be considered strategies for impactingthese outcomes

Risco de excesso de peso/gordura corporal e dislipidemias, associadas aos níveis de hemoglobina A2 / Risk of overweight/body fat and dyslipidemia, associated with the levels of hemoglobin A2

Objetivo: estimar o risco do excesso de peso/gordura corporal e dislipidemias, associados aos níveis de hemoglobina A2(HbA2) em população afrodescendente da Amazônia brasileira.Método: estudo analítico transversal,com 182 quilombolas de Trombetas, Pará Brasil, maiores de 20 anos; 41,7% homens e 58,3% mulheres. As variáveis do estudo foram: níveis de HbA2 <2,5%, 2,5-3,5% e >3,5% (variável dependente); medidas antropométricas (Índice de Massa Corporal-IMC, % de Gordura Corporal- BIA; circunferência da cintura ? CC), Colesterol e Triglicerídeo (variáveis independentes). Utilizaram-se médias de tendência central e dispersão, prevalência e teste de associação Qui-quadrado e Odds Ratio, entre as variáveis considerando, separadamente, grupos de acordo com HbA2, para a ocorrência de sobrepeso, excesso de gordura corporal, obesidade abdominal, hipercolesterolemia e hipertrigliceridemia, considerando positivo(?1) e negativo(<1), utilizando o nível de significância 5% (p?0,05). Resultados: para HbA2 <2,5% houve excesso de peso 69,0% sendo, estatisticamente, significante p valor(0,03), excesso de gordura 58,6%, obesidade abdominal 35,7%, hipertrigliceridemia 19,0% e hipercolesterolemia 57,1%. HbA2 2,5-3,5%, as maiores prevalências foram, excesso de peso e hipercolesterolemia (50,4% e 67,8% respectivamente); o risco aumentava para todas as morbidades exceto para hipercolesterolemia. Na HbA2 >3,5%,as maiores prevalências foram a obesidade abdominal e hipertrigliceridemia e os riscos foram menores para essas morbidades. Conclusão: o risco para o excesso de peso passou de 0,49 para 1,42 vezes de chance de ter essas morbidades, em relação aos níveis de concentração de HbA2 <2,5% e >3,5% respectivamente

Objective: estimate the risk of overweight/body fat and dyslipidemias, associated with levels of hemoglobin A2 (HbA2) population of African descents in the Brazilian Amazon. Method: study with 182 African descendent of Trombetas-Pará, more than 20 years, 41.7% men, 58.3% women. Variables: HbA2 categorized as <2.5%, from 2.5 to 3.5% and > 3.5% (low, normal and high, respectively), anthropometric measures (body mass index -BMI, Body Fat %-BIA, Abdominal fat - WC), cholesterol and triglyceride (independent variables). Analysis: means of central tendency and dispersion, prevalence and association test chi-square and the estimated risk (odds ratio) between the variables considering separately the groups according to the levels of HbA2 (dependent variable) for the occurrence of overweight, excess body fat, abdominal obesity, hypercholesterolemia and hypertriglyceridemia (independent variables), considering the positives(?1) ,negatives(<1). Statistical Package for the Social Sciences (SPSS) and in all tests was set the significance level of 5% (p ? 0.05). Results: HbA2 < 2.5% there were prevalence of overweight of 69.0% with a statistically significant p value (0.03), fat excess 58.6%, abdominal obesity 35,7%, hypertriglyceridemia 19.0% and hypercholesterolemia 57.1%. HbA2 2.5-3.5% the highest prevalence were overweight and hypercholesterolemia with 50.4% and 67.8% respectively, while the risk increased for all morbidities except for hypercholesterolemia. HbA2> 3.5%, the highest prevalence were abdominal obesity and hypertriglyceridemia and the risks were lower for these morbidities. Conclusion: however we note that the risk for being overweight increased from 0.49 to 1.42 times likely to have these illnesses when levels of HbA2 increased from <2.5% to> 3.5% respectively.

Avaliação do estado nutricional da comunidade indígena Kaingang. Área Monte Caseiros - Muliterno RS / Evaluation of the nutricional status of the Kaingang indigenous community. Monte Caseiros Area - Muliterno RS

A obesidade tornou-se um problema mundial, no qual a dieta alimentar não-balanceada contribui, e muito, para o aumento de peso. Realizou-se um estudo com o objetivo de conhecer a prevalência da obesidade e dos fatores de risco que levam ao desenvolvimento dessa patologia, dando ênfase a alguns fatores de risco e o perfil alimentar da comunidade indígena da Estratégia da Saúde da Família da Aldeia Monte Caseiros de Muliterno (RS). Foram entrevistados, por meio de questionários, medidos e pesados 143 indivíduos, maiores de 20 anos e registrados no Programa SIASI - 2008. Foram avaliados pelo índice de massa corporal (IMC), e os resultados foram: 40% de obesos, 38% de pessoas com sobrepeso e apenas 22% com o peso adequado. No grau de obesidade, 60% são mulheres, 80% realizam três refeições diárias, 95% preparam a refeição com banha de porco e 49% não realizam nenhuma atividade física. De modo semelhante a outros estudos com populações distintas, conclui-se que, entre os Kaingangs, o sobrepeso e a obesidade acometem um grande número de indivíduos.

The obesity became a world wide health problem, which a non-balanced diet contributes significantly for the weight increasement. A study was made to know the obesity prevalence and risk factors that contribute with the development of this patology, emphasizing some risk factors and the alimentary profile of Indígena Community for Family Health Strategy of Monte Caseiros Village from Muliterno, RS, Brazil. Interviews were made, within questionnaire, tallness and weight measurement (143 individuals, 20 years old higher aged, registered on SIASI Program - 2008. Body Mass Index was considered and the result was that: 40% individuals with obesity, 38% overweight and just 22% on suitable weight. In obesity level, 60% are women, 80% have 3 daily meals, 95% prepare their meals with pig grease and 49% don.t exercise. Comparing other studies with other people, different than this one, we can conclude that among the Kaingangs, overweight and the obesity affect a big number of individuals.
