- Item3-Epi-25 Serum 25-Hydroxyvitamin D3 Concentrations in Chilean Children Between 5 and 8 Years(KARGER, 2018) Arancibia, Monica; Seiltgens, Cristian; Poggi, Helena; Allende, Fidel; Solari, Sandra; Peredo, Soledad; Trincado, Claudia; Garcia, Hernan; Moore, Rosario; Dapremont, Ivonne; Andrade, Daniela; Sifaqui, Sofia; Ossa, Jt; Campino, Carmen; Carvajal, Cristian; Fardella, Carlos; Baudrand, Rene; Sanchez, Ximena; Martinez Aguayo, Alejandro
- ItemExtremely and very preterm children who were born appropriate for gestational age show no differences in cortisol concentrations or diurnal rhythms compared to full-term children(2023) Dominguez-Menendez, Gonzalo; Poggi, Helena; Ochoa-Molina, Fernanda; D'Apremont, Ivonne; Moore, Rosario; Allende, Fidel; Solari, Sandra; Martinez-Aguayo, AlejandroObjectives: The objective of this study was to compare the diurnal variations in cortisol and cortisone concentrations in serum and saliva among extremely preterm (EPT), very preterm (VPT), and full-term (FT) children, all born appropriate for gestational age (AGA).Methods: EPT, VPT, and FT children, all born AGA, were recruited from two healthcare centers. Cortisol and cortisone concentrations in serum and saliva were measured by liquid chromatography-mass spectrometry (LC-MS). Statistical analysis was performed using nonparametric tests.Results: A total of 101 children (5.0-8.9 years old) were included in this study: EPT=18, VPT=43 and FT=40. All groups had similar distributions in terms of age, birth weight standard deviation score (SDS) and BMI (SDS), showing no differences in serum ACTH, cortisol, or cortisone levels. Additionally, salivary cortisol and cortisone concentrations decreased significantly throughout the day (p values<0.0001). Salivary cortisol concentrations were below the limit of detection (0.55 nmol/L) before dinner and before bedtime in approximately one-third and two-thirds of all children, respectively. Salivary cortisone was detectable in all but one sample.Conclusions: The diurnal cortisol rhythm was preserved in all preterm children, regardless of their gestational age, and no differences in cortisol concentrations among the groups were found. This may have significant implications for the clinical management and follow-up of preterm individuals.
- 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
- ItemImportance of cross-cultural adjustment of M-CHAT R/F in the process of validation as an Autism Test(SOC CHILENA PEDIATRIA, 2017) Elisa Coelho Medeiros, Maria; Bronstein, Jonathan; Aedo, Karina; Pereira, Jaime A.; Arrano, Veronica; Perez, Carolina A.; Valenzuela, Patricia M.; Moore, Rosario; Garrido, Isabel; Bedregal, Paula
- 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.
- ItemInsulin Resistance Parameters in Children Who Were Born Very Preterm and Adequate for Gestational Age(KARGER, 2018) Garcia, Hernan; Poggi, Helena; Arancibia, Monica; Peredo, Soledad; Trincado, Claudia; Moore, Rosario; D'Apremont, Ivonne; Andrade, Daniela; Sifaqui, Sofia; Ossa, J.

- ItemM-CHAT-R/F Validation as a screening tool for early detection in children with autism spectrum disorder(SOC CHILENA PEDIATRIA, 2019) Elisa Coelho Mcdeiros, Maria; Bronstein, Jonathan; Aedo, Karim; Pereira, Jaime A.; Arrano, Veronica; Perez, Carolina A.; Valenzuela, Patricia M.; Moore, Rosario; Garrido, Isabel; Bedregal, PaulaIntroduction: Screening for Autism Spectrum Disorders (ASD) using the Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F) increases early detection, allowing early interventions and improving prognosis. This tool is part of the management in case of suspected ASD in several clinical guidelines. The objective of this article was to conduct the concurrent and discriminant validation and the reliability analysis of M-CHAT-R/F in the Chilean population. Patients and Method This is the second stage of the cross-cultural adaptation of cross-sectional design. M-CHATR/F was applied to a sample of 20 children with suspected ASD and 100 randomly selected healthy control children, aged between 16-30 months. Autism Diagnostic Observation Schedule (ADOS-2), considered as reference, was applied to the 20 patients of the clinical sample, to 20 children of the healthy control sample and to those cases of the healthy control sample with M-CHAT-R/F positive. Cronbach alpha was calculated, as well as M-CHAT-R/F and ADOS-2 correlation, sensitivity, and specificity analyses. Results: In the healthy sample, M-CHAT-R/F was positive in two patients, with one of them positive and the other one negative for ASD with ADOS-2 test. In the clinical sample, M-CHAT-R/F was positive in all cases, three of them were negative in the ADOS-2 test. The Alfa reliability of M-CHART-R/T was 0,889, the discriminant sensitivity and specificity were 100% and 98%, and the concurrent ones were 100% and 87.5% respectively. Conclusions: The Chilean M-CHAT-R/F version was reliable, sensitive and specific, similar to the original test, which opens the possibility for its use in clinical samples and for research. Validating M-CHAT-R/F is an ongoing process which must be further developed.
