Artigo Bioelectrical impedance vector analysis and phase angle in boys with Duchenne muscular dystrophy(Food & nutrition research, 2019) Lopes, Márcia Marília Gomes Dantas; Vermeulen, Karina Marques; Grilo, Evellyn C.; Alves, Camila X.; Machado, Richele J. A.; Lais, Lucia L.; Brandão Neto, José; Vale. Sancha H. L.; https://orcid.org/0000-0002-0011-576XBackground: Duchenne muscular dystrophy (DMD) is a disease characterized by progressive loss of functional muscle mass followed by changes in body composition. Objective: This study aimed to describe and evaluate bioimpedance parameters in boys with DMD. Design: This cross-sectional, descriptive study investigated children and adolescents diagnosed with DMD. Age, weight, height, resistance, and reactance data were collected. Phase angle and bioelectrical impedance vector analysis were calculated based on resistance and reactance values. Results: We analyzed 43 boys aged between 2.7 and 19.8 years. Low-phase angle values were observed during the investigation of bioimpedance parameters. Bioelectrical impedance vector analysis showed that approx- imately 87% of the subjects presented vectors outside the tolerance ellipses, and only one patient presented vectors located within the 50% tolerance ellipse, indicating normally hydrated and a good body cell mass. Compared with the reference population, boys with DMD had lower levels of body cell mass. Conclusion: Based on the evidence, compared with the reference population, patients with DMD had lower levels of body cell mass. This evidence points to bioimpedance parameters as useful tools for the nutritional evaluation and clinical management of patients with DMD.Artigo Validity of bioelectrical impedance to estimate fat-free mass in boys with Duchenne muscular dystrophy(Plos One, 2020) Dourado Junior, Mário Emílio Teixeira; Grilo, Evellyn C.; Cunha, Thais A.; Costa, Ádila Danielly S.; Araújo, Bárbara G. M.; Lopes, Márcia Marília G. D.; Maciel, Bruna L. L.; Alves, Camila X.; Serpa, Karina M. Vermeulen; Lais, Lucia Leite; Brandão-Neto, José; Vale, Sancha Helena L.; https://orcid.org/0000-0002-9462-2294The evaluation of fat-free mass (FFM) in patients with Duchenne muscular dystrophy (DMD) is useful to investigate disease progression and therapeutic efficacy. This study aimed to validate the Bioelectrical impedance (BIA) method compared with the dual-energy X-ray absorptiometry (DXA) for estimating the %FFM in boys with DMD. This is a cross-sectional study performed with children and adolescents diagnosed with DMD. Resistance and reactance were measured with a BIA analyzer, from which eight predictive equations estimated the %FFM. The %FFM was also determined by DXA and its used as a reference method. Pearson correlation test, coefficient of determination, the root-mean-square error, the interclass correlation coefficient, and linear regression analysis were performed between %FFM values obtained by BIA and DXA. The agreement between these values was verified with the Bland-Altman plot analysis. Forty-six boys aged from 5 to 20 years were enrolled in the study. All the equations showed a correlation between the %FFM estimated by BIA and determined by DXA (p < 0.05). The Bland-Altman method indicated that two equations have a significant bias (p < 0.05) and six equations showed no significant bias of %FFM (p > 0.05). However, one of them has high variation and wide limits of agreement. Five of eight %FFM predictive equations tested in DMD were accurate when compared with the DXA. It can be concluded that BIA is a validity method to evaluate patients with DMD.Artigo Vitamin A nutritional status in high- and low-income postpartum women and its effect on colostrum and the requirements of the term newborn(Jornal de Pediatria, 2018-03) Lyra, Clélia de Oliveira; Gurgel, Cristiane Santos Sânzio; Grilo, Evellyn C.; Lira, Larissa Q.; Assusnção, Débora G.F.; Oliveira, Priscila G.; Melo, Larisse R.M. de; Medeiros, Silvia V. de; Peçanha, Luanna C.; Dimenstein, RobertoObjective: To evaluate the vitamin A status in serum and colostrum of postpartum women with different socioeconomic status, comparing the colostrum retinol supply with the vitamin A requirement of the newborn. Methods: Cross-sectional study conducted with 424 postpartum women. Vitamin A maternal dietary intake was estimated using a food frequency questionnaire. Colostrum and serum retinol levels were measured by high performance liquid chromatography (HPLC). Serum retinol concentrations <20 g/dL were indicative of vitamin A deficiency (VAD). Vitamin A levels provided by colostrum <400 gRAE/day were considered as insufficient for term newborns. Results: The mean maternal vitamin A intake during pregnancy was 872.2 ± 639.2 gRAE/day in low-income women and 1169.2 ± 695.2 gRAE/day for high-income women (p < 0.005). The prevalence of vitamin A deficiency was 6.9% (n = 18) in the low-income group and 3.7% (n = 6) in the high-income group. The estimated mean retinol intake by infants of the highand low-income mothers were 343.3 gRAE/day (85.8% AI) and 427.2 gRAE/day (106.8% AI), respectively
