Association between sarcopenic obesity and cardiovascular risk: where are we?

INTRODUCTION: The main changes in the body composition refer to the increase of adipose tissue and/or the decrease of muscular mass, and these changes have effect in many clinical outcomes. Sarcopenic obesity (SO) consists of the presence of excessive adipose tissue and deficit of muscular mass simultaneously. People with SO may have synergistic effect due to obesity and sarcopenia, with increases cardiovascular risk more than obesity itself. OBJECTIVE: To describe the findings in the literature about the association between SO and risk factors and/or cardiometabolic disease (CMD) or cardiovascular disease (CVD). METHODS: An electronic search was done on the following databases: MEDLINE, Scopus, SciELO, LILACS and Web of Science, using the matching expressions and Boolean operators: "obesity sarcopenic" OR "sarcopenic obesity", in the titles of the studies, AND "cardiometabolic disease" OR "cardiovascular disease" OR "metabolic syndrome" OR "insulin resistance", in the abstract. RESULTS: Most of studies are cross-sectional and present many different diagnosis criteria for SO. It was possible to verify the association of the SO and the risk factors and/or CMD or CVD. CONCLUSION: SO is associated with risk factors and/or CMD or CVD. The lack of a consensus about this definition jeopardizes the effective clinical practice and the research about the subject.

Results: Most of studies are cross-sectional and present many different diagnosis criteria for SO. It was possible to verify the association of the SO and the risk factors and/or CMD or CVD.

Introducción: los principales cambios en la composición del cuerpo refi eren el incremento de tejido adiposo y/o la disminución de masa muscular, y estos cambios tienen efecto en varios resultados clínicos. La obesidad sarcopénica (OS) consiste en la presencia simultánea del exceso de tejido adiposo y el déficit de masa muscular. Las personas con OS pueden tener un efecto sinérgico debido a la obesidad y la sarcopenia, lo que incrementa el riesgo de enfermedad cardiovascular, más que la obesidad en sí. Objetivo: describir los hallazgos en la literatura científica sobre la asociación de la SO y los factores de riesgo y/o ECM (enfermedad cardiometabólica) o enfermedad cardiovascular (ECV). Métodos: se realizó una búsqueda electrónica en las siguientes bases de datos: MEDLINE, Scopus, SciELO, LILACS y Web of Science, usando las expresiones coincidentes y los operadores booleanos: «obesidad sarcopénica» o «sarcopénica obesidad», en los títulos de los estudios, y «enfermedad cardiometabólica» o «enfermedad cardiovascular» o «síndrome metabólico» o «resistencia a la insulina», en el abstract. Resultados: la mayoría de los estudios son de corte transversales y presentan diferentes criterios de diagnóstico para la OS. Fue posible verificar la asociación de la OS y los factores de riesgo y/o ECM o ECV. Conclusión: la OS está asociada con los factores de riesgo y/o ECM o ECV. La falta de un consenso sobre esta definición pone en peligro la efectividad de la práctica clínica y la investigación sobre el tema (AU)

OSAS in children: clinical and polysomnographic respiratory profile.

UNLABELLED: Obstructive sleep apnea and hypopnea syndrome in children (osas) has an estimated prevalence of up to 3% and can be associated with neurocognitive and behavioural abnormalities, and also cardiovascular complications. This study may help pediatricians, who are unaware of the problem, to recognize osas. STUDY DESIGN: series of cases. AIM: to describe the clinical characteristics and polysomnographic respiratory findings in a population of children with obstructive sleep apnea and hypopnea syndrome referred to the sleep laboratory from january 2002 up to july 2003. METHODS: we studied 93 patients between 2 and 10 years of age with polysomnographic diagnosis of obstructive sleep apnea and hypopnea syndrome. Age, gender, racial group and questions about the childrens health and sleep related disorders were evaluated. Apnea-hypopnea index, oxyhemoglobin desaturation, and arousal index were evaluated too. RESULTS: males represented 61.3%, With a mean age of 5.2+/-2.1 (Years-old). The complaints that most commonly lead to the exams were snoring in 24.7% And restless sleep in 24.7%. Associated medical conditions frequently reported were allergic rhinitis (98.9%) And adenoid hypertrophy (50.6%). Mild apnea was found in 66%. The mean and sd of spo2 nadir was 89.1+/-3.5% And the mean and sd of the number of arousals was 8.4+/-3.5/Hour of sleep. CONCLUSION: the results suggest the possibility that obstructive sleep apnea and hypopnea syndrome should be suspected in children with allergic diseases and adenoid and tonsil hypertrophy with snoring and restless sleep complaints.
