Breastfeeding seems to be a safe feeding practice for infants born at term and small for gestational age, showing no association with deleterious short-term outcomes. Breastfeeding stimulation in these populations seems to be a way of preventing the health problems associated with the high risk of chronic noncommunicable diseases and obesity.

Objetivo: el objetivo de este estudio fue evaluar la prevalencia de hipovitaminosis D en los candidatos a cirugía bariátrica (CB) y su relación con factores de riesgo y los componentes del síndrome metabólico. Material y métodos: los parámetros clínicos, antropométricos y bioquímicos se midieron en 56 pacientes caucásicos incluidos en un protocolo de cirugía bariátrica entre enero y junio de 2014. Los pacientes fueron estratificados en tres grupos de acuerdo al status de vitamina D: suficiencia (≥ 40 ng/ml), insuficiencia (40-20 ng/ml) y deficiencia (< 20 ng/ml). Resultados: se observó deficiencia de vitamina D en el 75% de los pacientes. Estos pacientes tenían mayor índice de masa corporal (p = 0,006) y concentraciones plasmáticas mas bajas de PTH (p = 0,045). Además, hubo más pacientes con diabetes mellitus tipo 2 (DM2) y dislipemia (DLPM) en el grupo con niveles de 25 (OH) D < 20 ng/ml. Asimismo la 25 (OH) D se correlacionó negativamente con la masa grasa (r =-0,504; p = 0,009), el IMC (r =-0,394; p = 0,046) y la hipertensión arterial (r =-0,637; p = 0,001). Conclusión: De nuestros hallazgos concluimos que la deficiencia de vitamina D es muy común entre los candidatos a CB y que la misma está asociada con DM2 y DLPM. Aunque hay pocos datos sobre el mejor tratamiento para el bajo nivel de vitamina D en los pacientes candidatos CB, la detección de la deficiencia de vitamina D debe realizarse de forma rutinaria en estos casos. 25-hydroxy vitamin D and syndrome metabolic components in candidates to bariatric surgery Vitamina D y componentes del síndrome metabólico en candidatos a cirugía bariátrica

There is little information about the congenital chikungunya virus (CHIKV) transmission. We describe two cases of well-documented congenital CHIKV infection in Salvador-Brazil, where CHIKV has been identified since 2014. The outbreak in the city led to the clinical CHIKV diagnoses of both pregnant women 2 days before delivery. Urine and blood samples from the mothers and newborns were collected and tested for reverse transcription-polymerase chain reaction (PCR) analysis for Zika, dengue, and CHIKV. Both neonates and mothers had positive urine and serum PCR results for CHIKV. The newborns had significant perinatal complications and were admitted to the neonatal intensive care unit. The purpose of our case report is to show how severe congenital CHIKV infection can be and the importance to include CHIKV infection in the differential diagnosis of neonatal sepsis when mothers have clinical signs of the disease and live in an affected area.

Introduction: Being born small for gestational age (SGA) implies an increase in the childhood morbidity and mortality rates, in addition to being related to changes in the pattern of growth and body composition, which may be associated with the development of risk factors linked to metabolic diseases. Aim of the study: To describe the development of anthropomorphic indicators of children born at full term, small (SGA) or appropriate for gestational age (AGA), up to the sixth month of life, and again when they reached school-age. Material and methods: This was a prospective cohort study, with 31 children (19 SGA, and 12 AGA), recruited in public maternity hospitals. Subsequently they were attended at an outpatient clinic on a monthly basis, by a multidisciplinary team in the first year of life. These children were re-evaluated when they reached school-age. Results: Both groups showed high percentages of exclusive breastfeeding in the first months of life. Group SGA showed intense early recovery of the growth indicators, characterizing recovery of growth in the first 6 months of life. However, at school-age, they were still smaller, lighter, with a lower quantity of body fat and muscle mass than those born AGA. There was predominance of appropriate anthropometric growth and body composition indicators at school-age, even in Group SGA. Conclusion: At school-age, the children of this study showed no major alterations related to anthropometry.
