ABSTRACT
Abstract Objective: To evaluate the correlation between hemoglobin levels of mothers and their children on exclusive breastfeeding in the first six months of life. Methods: Cross-sectional study with 221 binomials (mother-child) enrolled in a breastfeeding support program, who were stratified into six groups according to the children's age group. The sample consisted of children born at term with normal weight, with no neonatal complications and whose mothers did not have anemia or infectious disease at the time of data collection. Interviews were carried out with the mothers, blood was collected by peripheral venipuncture from mothers and children, and children's anthropometric data were assessed. Pearson's correlation coefficients between the hemoglobin levels of mothers and children were calculated. Six multiple linear regression models were adjusted with regression coefficient estimates, considering as statistically significant associations with p ≤ 0.05. Results: The correlation coefficients of hemoglobin levels of mothers and children ranged from 0.253, at three months, to 0.601, at five months. The hemoglobin level of mothers was correlated with the hemoglobin level of their children at four months (r = 0.578) and at five months (r = 0.601). In the adjusted multiple linear regression, the regression coefficients were higher at four months (β = 1.134; p = 0.002) and at five months (β = 0.845; p < 0.001). Conclusion: These findings allow for the conclusion that there is a correlation between the hemoglobin of mothers and the hemoglobin of their children on exclusive breastfeeding in the first six months of life.
Resumo Objetivo Avaliar a correlação entre os níveis de hemoglobina de mães e de seus filhos em aleitamento materno exclusivo, no primeiro semestre de vida. Métodos Estudo transversal com 221 binômios (mãe-filho) matriculados em programa de incentivo ao aleitamento materno, estratificados em seis grupos de acordo com a faixa etária das crianças. A amostra consistiu de crianças nascidas a termo, com peso normal, sem intercorrências neonatais e cujas mães não apresentavam doença infecciosa e anemia na época da coleta de dados. Foram feitas entrevistas com as mães, coleta de sangue por punção de veia periférica das mães e das crianças e antropometria das crianças. Foram calculados os coeficientes de correlação de Pearson entre os níveis de hemoglobina das mães e das crianças. Foram ajustados seis modelos de regressão linear múltiplos com estimativas de coeficientes de regressão, consideraram-se estatisticamente significantes associações com p ≤ 0,05. Resultados Os coeficientes de correlação dos níveis de hemoglobina das mães e das crianças variaram entre 0,253, aos três meses, e 0,601, aos cinco meses. O nível de hemoglobina das mães esteve mais correlacionado com o das crianças aos quatro meses (r = 0,578) e aos cinco meses (r = 0,601). Na regressão linear múltipla ajustada, os coeficientes de regressão foram maiores aos quatro meses (β = 1,134; p = 0,002) e aos cinco meses (β = 0,845; p < 0,001). Conclusão Esses achados permitem concluir que há correlação entre a hemoglobina de mães e a hemoglobina de seus filhos em aleitamento materno exclusivo no primeiro semestre de vida.

BACKGROUND: There is a gap in knowledge on the growth of children exclusively breastfed during the fifth and sixth months of life. This study aimed to assess the growth of infants who were exclusively breastfed for the first 6 months of life and compare the distributions of anthropometric measures based on the National Center for Health Statistics (NCHS, 1977) and World Health Organization (WHO, 2006) curves. METHODS: Cross-sectional study that measured the weight and length of 360 healthy and exclusively breastfed infants who were enrolled in a primary care program in Belem, Brazil from October 2006 to December 2008. The children were evenly grouped into age groups from 1 to 6 months of age. RESULTS: The mean weights were higher than the NCHS, 1977 mean weight for all of the studied groups regardless of gender and showed greater similarity to the WHO, 2006 mean weight, especially when standard deviations were considered. Regarding length, although the average length at birth was smaller, females had higher averages in the second and sixth months compared with the reference curves (p < 0.05). CONCLUSIONS: Exclusive breastfeeding in the first 6 months of life provides adequate physical growth, resulting in height and weight gain curves that are similar to or greater than the NCHS, 1977 and WHO, 2006 curves. The greater mean weight at the fifth and sixth months of life suggests that the second-quarter growth curves of children who are exclusively breastfed are greater than those of children who receive other types of food.
ABSTRACT
O câncer é um dos maiores causadores de óbito na história recente da humanidade, sendo o de endométrio o sétimo mais frequente entre as mulheres no mundo. Medidas do endométrio em torno de 4 ou 5 mm possui sensibilidade em torno de 95% para a detecção desta neoplasia uterina. Porém, esse ponto de corte vem sendo contestado pelo fato de submeter muitos pacientes a investigação endometrial desnecessária. Objetivos: Correlacionar a espessura endometrial com o diagnóstico de câncer de endométrio, visando estabelecer um novo ponto de corte. Materiais e Métodos: Foi realizado análise de 382 prontuários de pacientes que se submeteram à curetagem uterina no período de janeiro de 2010 a maio de 2013, no Setor de Ginecologia do Hospital do Servidor Público Municipal de São Paulo (HSPM). As variáveis estudadas foram: espessura endometrial, diagnóstico histopatológico, idade, sangramento, uso de terapia de reposição hormonal (TRH) e uso de tamoxifeno. Resultados: Apenas 5% das curetagens uterinas foram enquadradas no diagnóstico de adenocarcinoma de endométrio. Em relação as variáveis estudadas apenas o uso de TRH não apresentou correlação estatisticamente significativa com o câncer de endométrio. O melhor ponto de corte para investigação desta neoplasia, após a confecção de uma curva ROC, foi de 11,55 mm com uma sensibilidade de 68,2 % e uma especificidade de 63,7%. Conclusão: Após correlacionar a espessura endometrial com o diagnóstico de câncer de endométrio, o melhor ponto de corte encontrado foi de 11,55 mm.
