RESUMO
Purpose: To evaluate the repeatability of biometry and intraocular lens (IOL) power using Galilei G6 and to determine the agreement of its measurements with those of IOL Master 700 and IOL Master 500. Methods: Hundred mature cataract eyes were examined twice with Galilei G6 and the results were compared with those of other two devices. Axial length (AL), minimum (K1), maximum (K2), and mean keratometry, anterior chamber depth (ACD), white-to-white (WTW) diameter, lens thickness (LT), and the calculated IOL power were the studied parameters. The correlation coefficient, within-subject standard deviation (Sw), Bland–Altman method, and 95% limits of agreement (LoA) were used for statistical analysis. Results: The intraclass correlation coefficient (ICC) was above 0.9 for all indices, and the LoA ranged from a minimum of 0.08 mm for AL to a maximum of 0.50 D for K1. Sw also ranged between a minimum of 0.02 for AL, ACD, and WTW and a maximum of 0.13 for K1. In the Galilei G6–IOL Master 700 pair, the narrowest and widest LoA were calculated for AL (0.07 mm) and K2 (0.49 D), respectively. In the Galilei G6–IOL Master 500 pair, the narrowest and widest widths of LoA were calculated for AL (0.17 mm) and K2 (0.92 D), respectively. In the first pair, the LoA of IOL power (0.57 D) were the best for Haigis formula and in the second pair, the best agreement (LoA: 0.35 D) was observed for Holladay-1. Conclusion: Galilei G6 provided repeatable biometric measurements. The agreement between biometry and IOL power calculation was better in the Galilei G6–IOL Master 700 pair compared to the Galilei G6–IOL Master 500
RESUMO
RESUMEN Objetivo: evaluar el grado de concordancia entre el modelo de evaluación del estado nutricional materna propuesto por Rosso-Mardones con el propuesto por Atalah Materiales y métodos: estudio de concordancia diagnóstica. Se incluyeron gestantes entre los 19 y 37 años, con una edad gestacional de 10 o más semanas; se excluyeron gestantes con: diabetes, enfermedad tiroidea, hipertensión asociada al embarazo, embarazos gemelares, malformaciones fetales graves, muerte fetal e hidrops fetalis. Muestreo no probabilístico. Se midieron las variables sociodemográficas, obstétricas y el estado nutricional. Se calculó el valor de kappa de concordancia entre las dos escalas de evaluación nutricional. Conclusiones: las escalas de evaluación nutricional en gestantes, nomograma de Rosso-Mardones y de Atalah, tienen un acuerdo considerable. Se requieren más estudios que evalúen la concordancia entre estas escalas en población gestante.
ABSTRACT Objective: To assess the degree of agreement between the model for maternal nutritional assessment proposed by Rosso-Mardones and the one proposed by Atalah. Materials and methods: Diagnostic agreement study. Pregnant women between the ages of 19 and 37 years with a gestational age of 10 or more weeks were included; patients with diabetes, thyroid disease, pregnancy-associated hypertension, twin pregnancy, severe fetal malformation, fetal death and hydrops fetalis were excluded. Non-probabilistic sampling. Sociodemographic, obstetrical and nutritional status variables were measured. Results: Overall, 98 pregnant women were included. With the use of the Rosso-Mardones scale, 33% of the patients were classified as having a normal nutritional status, 22% as low weight, and 44% as overweight or obese. With the Atalah scale, 41% of the women were classified as having a normal nutritional status, 10% as low weight and 48% as overweight or obese. The weighted kappa value was 0.74 with a standard error of 0.04, a 95% CI of 0.66-0.82 and a p value < 0.05. Conclusions: There is substantial agreement between nutritional assessment scales used in pregnancy, namely the Rosso-Mardones nomogram and the Atalah scale. Further studies to assess the agreement of these scales in the pregnant population are required.
