- ItemHigher Dehydroepiandrosterone Levels in Prepubertal Children Born Very Preterm(KARGER, 2018) Mericq, Veronica; Martinez Aguayo, Alejandro; Iniguez, German; Poggi, Helena; D'Apremont, Ivonne; Moore, Rosario; Arancibia, Monica; Garcia, Hernan; Peredo, Soledad; Trincado, Claudia; Sifaqui, Sofia; Tomas Ossa, Jose; Fardella, Carlos; Carvajal, Cristian; Campino, Carmen; Baudrand, Rene; Solari, Sandra; Allende, Fidel
- ItemInsulin resistance parameters in children born very preterm and adequate for gestational age(WILEY, 2022) Garcia, Hernan; Loureiro, Carolina; Poggi, Helena; D'Apremont, Ivonne; Moore, Rosario; Ossa, Jose Tomas; Bruera, Maria Jose; Peredo, Soledad; Carvajal, Jacqueline; Trincado, Claudia; Martinez Aguayo, AlejandroBackground Preterm neonates are at risk for metabolic syndrome later in life. Whether prematurity constitutes an independent risk factor for the development of cardiovascular disease and metabolic syndrome remains controversial. Objective To compare anthropometric measures, cardiometabolic risk factors and insulin resistance variables between children who were born very preterm (VPT, <32 gestational weeks) and at term (Term, >37 gestational weeks) and adequate for gestational age (AGA). Methods We designed a cross-sectional cohort study, recruiting 120 children (5.0-8.5 years old) from the preterm clinic at Red de Salud UC-Christus and Complejo Asistencial Dr. Sotero del Rio, and term children from the community. We excluded children born small for gestational age, based on INTERGROWTH21. Anthropometrics data were classified using WHO reference standards. The homeostasis model assessment insulin resistance (HOMA-IR) index, quantitative insulin sensitivity check index (QUICKI), triglyceride-to-HDL-C ratio (TG/HDL-C) and Pediatric Score Index for Metabolic Syndrome (PsiMS) were calculated. Results VPT children born AGA had lower HDL cholesterol levels (p = .019) and a higher PsiMS score than those born at term (p = .043). We observed a higher percentage of children with HDL cholesterol <= 40 mg/dl (13.0% vs. 2.3%, p = .026) and BP >= 90th percentile among the VPT children than among the Term children (26.0% vs. 11.6%, p = .031). Conclusions At school age, blood pressure was higher, and HDL-C was lower among VPT children born AGA, suggesting a potential metabolic risk; therefore, it is essential to follow this group throughout their lives.

- ItemMortality in very low birth weight (VLBW) infants in South American NEOCOSUR Neonatal Network: timing and causes(2022) Toso, Alberto; Vaz Ferreira, C.; Herrera, T.; Villarroel del Pino, Luis A.; Brusadin, M.; Escalante Rivas, María José; Masoli, Daniela; D'Apremont, Ivonne; Tapia Illanes, José Luis; Mariani, G.Sociedad Argentina de Pediatría.INTRODUCTION: Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network. OBJECTIVE: Mortality in very low birth weight infants (VLBWIs) has remained at ~26% in the past 16 years in the NEOCOSUR Neonatal Network. POPULATION AND METHODS: Observational, multicenter cohort study; retrospective analysis of data collected prospectively. Newborn infants born between 24 and 31+6 weeks of gestation age with a birth weight between 500 and 1500 g in the 26 sites of the NEOCOSUR Neonatal Network were included. The causes of death were analyzed depending on whether they occurred in the delivery room (DR) or in the neonatal intensive care unit (NICU). The postnatal age at time of death was determined using the KaplanMeier test. RESULTS: Observational, multicenter cohort study; retrospective analysis of data collected prospectively. Newborn infants born between 24 and 31+6 weeks of gestation age with a birth weight between 500 and 1500 g in the 26 sites of the NEOCOSUR Neonatal Network were included. The causes of death were analyzed depending on whether they occurred in the delivery room (DR) or in the neonatal intensive care unit (NICU). The postnatal age at time of death was determined using the KaplanMeier test. CONCLUSIONS: Important differences were observed in the causes of death of VLBWIs depending on their occurrence in the DR or the NICU. Infectious and respiratory conditions were the most relevant factors following admission to the NICU.Introducción. La mortalidad de los recién nacidos de muy bajo peso de nacimiento (RNMBPN) se ha mantenido en ~26 % en los últimos 16 años en la Red Neonatal NEOCOSUR. Objetivo. Determinar la causa de muerte de los RNMBPN y su temporalidad en el período 20072016 en la Red Neonatal NEOCOSUR. Población y métodos. Estudio observacional de cohorte multicéntrica; análisis retrospectivo de datos obtenidos prospectivamente. Se incluyeron recién nacidos entre 24 y 31+6 semanas de edad gestacional y peso de nacimiento de 500-1500 g, en 26 centros de la Red Neonatal NEOCOSUR. Las causas de muerte se analizaron según ocurriera en sala de partos (SP) o durante la estadía en la unidad de cuidados intensivos neonatales (UCIN). La edad posnatal de muerte se determinó a través de análisis de Kaplan-Meier. Resultados. Se incluyeron un total de 11753 RNMBPN con una mortalidad global del 25,6 %. Las causas de muerte predominantes en SP fueron malformaciones congénitas (43,3 %), enfermedades respiratorias (14,3 %) y prematuridad (11,4 %). Las causas de muerte predominantes en UCIN fueron las respiratorias (24,2 %) e infecciosas (24,1 %). La edad promedio de muerte fue de 10,2 días y mediana de 4 días. El 10,2 % de las muertes ocurrieron en SP; el 21,5 %, durante el primer día; el 52 % ocurrió en los primeros 4 días y el 63,8 %, durante la primera semana de vida. , A través de los años, la mortalidad de los recién nacidos de muy bajo peso de nacimiento (RNMBPN) se ha mantenido estable, en torno al 26 % en la Red Neonatal NEOCOSUR.1 Esta mortalidad es mayor que la reportada por otras redes neonatales de países desarrollados. Así, los datos de la Red Suiza dan cuenta de una mortalidad de solo un 11 % entre los años 2012 a 2014 para el mismo grupo de recién nacidos.2 La red internacional iNEO, que agrupa 10 redes a lo largo del mundo, describe una mortalidad global del 9,1 % en RNMBPN de entre 24 a 32 semanas de edad gestacional entre los años 2007 y 2015.3 Por otra parte, la Red Neonatal Brasilera informa una mortalidad de 30 % en RNMBPN.4 f. Red Neonatal del Cono Sur (www. neocosur.org). Correspondencia: Alberto Toso: aatoso@ uc.cl Financiamiento: Ninguno. Conflicto de intereses: Ninguno que declarar. Recibido: 12-8-2021 Aceptado: 12-1-2022 Conclusiones. Se encuentran importantes diferencias en las causas de muerte de RNMBPN según ocurra en SP o en UCIN. Las infecciosas y respiratorias son las más relevantes luego del ingreso a la unidad de cuidados intensivos.

- ItemThe unfinished work of neonatal very low birthweight infants quality improvement: Improving outcomes at a continental level in South America(2021) Tapia Illanes, José Luis; Toso, Alberto; Vaz Ferreira, C.; Fabres Biggs, Jorge Guillermo Eduardo; Musante, G.; Mariani, G.; Herrera, T., I; D'Apremont, IvonneNeonatal mortality rate varies between 4.2 and 18.6 per thousand by country in South America. There is little information regarding the outcomes of very low birth weight infants in the region and mortality rates are extremely variable ranging from 6% to over 50%. This group may represent up to 50-70% of the neonatal mortality and approximately 25-30% of infant mortality. Some initiatives, like the NEOCOSUR Network, have systematically collected and analyzed epidemiological information on VLBW infants' outcomes in the region. Over a 16-year period, survival without major morbidity improved from 37 to 44%. However, mortality has remained almost unchanged at approximately 27%, despite an increase in the implementation of the best available evidence in perinatal practices over time. Implementing quality improvement initiatives in the continent is particularly challenging but represents a great opportunity considering that there is a wide margin for progress in both care and outcomes.
