Heart rate variability in the evaluation of the autonomic nervous system of premature infants.

One way to analyze the function of the autonomic nervous system (ANS) is through heart rate variability (HRV). This approach is based on the analysis of the distance between the peaks of two consecutive R waves expressed in electrocardiograms. HRV evaluations have been developed and have become more accessible and reliable through technological advances that enable the data collection in a simpler, non-invasive, and reliable way. However, there is little information in the scientific literature on the implementation of this methodology to assess the ANS of preterm infants. In this article, we survey the barriers, potential uses, and other topics regarding the assessment of the ANS in preterm infants using HRV.

Association between food intake and anthropometric and metabolic profile of brazilian adult women / Asociación entre ingesta alimentaria y perfil antropométrico y metabólico de mujeres adultas brasileñas

INTRODUCTION: alterations in the lipid, glycemic and hemodynamic profile may increase the risk of developing chronic diseases and mortality. OBJECTIVE: associate the metabolic and anthropometric parameters and food intake of Brazilian adult women. METHODS: a cross-sectional study was conducted with 34 Brazilian women aged 20-59 years old. Alcohol consumption, smoking, physical exercise, blood pressure, anthropometric and food intake data were collected. Glycated hemoglobin and lipid fractions were also evaluated. RESULTS: there was a positive association between energy consumption and body mass (ß = 0.377, p = 0.028) and waist circumference (ß = 0.373, p = 0.030), and between protein intake and body fat percentage (ß = 0.368, p = 0.032). There was also a positive association between waist circumference and the values of glycated hemoglobin (ß = 0.401, p = 0.019), and HDL-cholesterol was influenced directly by protein intake (ß = 0.573, p = 0.013) and inversely by lipid intake (ß = -0.597, p = 0.010). CONCLUSION: anthropometry, metabolic profile and food intake were associated among the Brazilian adult women evaluated.(AU)

INTRODUCCION: las alteraciones en el perfil lipídico, glucémico y hemodinámico pueden aumentar el riesgo de enfermedades crónicas y mortalidad. OBJETIVO: asociar los parámetros metabólicos, antropométricos y el consumo de alimentos de mujeres adultas brasileñas. Métodos: Se realizó un estudio transversal con 34 mujeres brasileñas de 20 a 59 años. Se recogieron datos sobre el consumo de alcohol, tabaco, ejercicio, presión arterial, antropometría y consumo de alimentos. También se evaluaron la hemoglobina glicosilada y las fracciones lipídicas. RESULTADOS: se encontró una asociación positiva entre el consumo de energía y los valores de masa corporal (ß = 0.377, p = 0.028) y la circunferencia de la cintura (ß = 0.373, p = 0.030), y entre el consumo de proteínas y el porcentaje de grasa corporal (ß = 0.368, p = 0.032). También hubo una influencia positiva de la circunferencia de la cintura en los valores de hemoglobina glicosilada (ß = 0.401, p = 0.019), y el HDL-c estuvo directamente influenciado por el consumo de proteínas (ß = 0.573, p = 0.013) e inversamente por el consumo de grasas (ß =-0.597, p = 0.010). CONCLUSION: la antropometría, el perfil metabólico y el consumo de alimentos se asociaron entre las mujeres adultas brasileñas evaluadas.
