    (2024) Vaz Ferreira, Catalina; Caro, Jose; Villarroel del Pino, Luis A.; Muñoz, Sergio; Álvarez, Patricia; Flores, Gerardo; Herrera, Tamara; Toso, Alberto; Toso Milos, Paulina Alejandra; Tapia Illanes, José Luis; NEOCOSUR Neonatal Network
    Objective: To explore the association between antenatal magnesium sulfate (MgSO4), mortality and incidence of intraventricular hemorrhage (IVH) in very low birth weight (VLBW) infants. Study design: Retrospective, cohort study of infants <32 weeks’ GA born at centers of NEOCOSUR Network between January 2015 and December 2020. Subjects were categorized as exposed vs non-exposed to antenatal MgSO4. Primary outcomes were death, incidence of severe IVH (Grade III-IV) and severe IVH/death. Secondary outcomes included relevant morbidities. Results: 7418 VLBW infants were eligible. Antenatal MgSO4 was associated with a significantly decreased death rate after admission (aOR 0.67 [95% CI, 0.49–0.94]) and severe IVH/ death (aOR 0.68 [95% CI, 0.50–0.93]). No significant reduction in severe IVH was observed (aOR 1.11 [95% CI, 0.72–1.71]). No differences between groups were observed in rates of morbidities. Conclusion: Antenatal MgSO4 was associated with a decreased death rate after admission and in severe IVH/ death.

    ASSOCIATION OF SUBCLINICAL ATHEROSCLEROSIS WITH DIFFERENT STANDARDS OF THE METABOLIC SYNDROME AND INSULIN RESISTANCE
    (2013) Arnai, P.; Dominguez, Angélica; Barja Y., Salesa; Godoy, I.; Villarroel del Pino, Luis A.; Castillo Valenzuela, Oscar; Farías Jofré, Marcelo; Mardones, Francisco
    Background and objectives: we have previously selected two metabolic syndrome (MS) components blood pressure (BP) and high density lipoprotein cholesterol (HDLC) as associated with carotid intima media thickness (CIMT) a surrogate marker of subclinical atherosclerosis in children (Rev Med Chile 2012; 140: 1268-75). We aimed to ascertain with a higher sample size the influence of the above mentioned variables and three standards defining the MS plus three standards defining insulin resistance (IR). Methods: A cross-sectional study of 447 children 10-14 years old of low socio-economic strata from an urban area of Chile was performed during years 2009-2011. This sample was selected considering the presence of one or more MS component and IR. Anthropometry and BP were assessed. A blood sample for determination of glycaemia, insulinemia (quimioluminiscence) and blood lipids were taken; HOMA was calculated and three standards were applied to select HOMA-IR cases. Three standards to define MS were also used. Medium CIMT was assessed using ultrasonography with automated software. Chi-squared test and stepwise regression were used. Results: Mean age was 11.5 ±1.0 years old; 59% girls; 92.6% pubertal; 72% excess weight. Three standards for MS had prevalence of 24.4% (Cook, 2004), 14.1% (IDF, 2007), 42.9% (De Ferranti, 2004). Three standards for HOMA-IR had the following prevalence: 15.2% (Barja, 2011), 37.4% (Burrows, 2006), 23.0% (De Onis, 2012). Elevated blood pressure and reduced CHDL had significant associations with CIMT ≥ percentile 75. The logistic regression for CIMT ≥ percentile 75 only selected BP ≥ percentile 90 (OR = 2.963) and CHDL < 40 mg/dL (OR = 1.789) Conclusions: None of the various classifications for the MS and the HOMA-IR were selected in the multivariate analysis confirming the previously found influence of increased BP and reduced CHDL on medium CIMT.

    Effect of a tele-care model on self-management and metabolic control among patients with type 2 diabetes in primary care centers in Santiago, Chile
    (2010) Lange Haensgen, Ilta Anita H.; Campos Romero, Solange; Urrutia Bunster, Mila; Bustamante Troncoso, Claudia Raquel; Alcayaga Rojas, Claudia Andrea; Tellez, Alvaro; Pérez Ewert, Janet Carola; Villarroel del Pino, Luis A.; Chamorro S., Gastón; O'Connor, Annette; Piette, John
    Telephone based self-management support may improve the metabolic control of patients with type 2 (DM2) diabetes if it is coordinated with primary care centers, if telephone protocols and clinical guidelines are used and if it is provided by nurses trained in motivational interviewing. Aim: To assess the efficacy ofi a tele-care self-management support model (ATAS) on metabolic control of patients with DM2 attending primary care centers in a low income area in Santiago, Chile. Material and Methods: Two primary care centers were randomly assigned to continue with usual care (control group, CG) or to receive additionally 6 telecare self-management support interventions (IG) during a 15 month period. Glycosylated hemoglobin (HbA1c) was used to measure metabolic control of DM2; the "Summary of Diabetes Self-care Activities Measure" and the "Spanish Diabetes Self-efficacy" scale were used to measure self-management and self efficacy, respectively. Changes in the use of health services were also evaluated. Results: The IG maintained its HbA1c level (baseline and final levels of 8.3 ± 2.3 % and 8.5 ± 2.2% respectively) whereas it deteriorated in the CG (baseline and final levels of 7.4 ± 2.3 and 8.8 ± 2.3 % respectively, p < 0.001). The perception of self-efficacy in the IG improved while remaining unchanged in the CG (p < 0.001). Adherence to medication, physical activity and foot care did not change in either group. In the IG, compliance to clinic visits increased while emergency care visits decreased. Conclusions: The ATAS intervention, in low income primary care centers, significantly increased the probability of stabilizing the metabolic control of patients with DM2 and improved their use of health services.

    Sexualidad en la mujer histerectomizada: Modelo predictivo al sexto mes posterior a la cirugía
    (2007) Urrutia Soto, María Teresa; Araya Gutiérrez, Alejandra; Rivera, Soledad; Viviani García, Paola; Villarroel del Pino, Luis A.
    Background: The effects of hysterectomy on sexuality has been extensively studied. Aim: To esta blish a model to predict the quality of sexual life in hysterectomized women, six months after surgery. Material and Methods: Analytical, longitudinal and prospective study of 90 hysterectomized women aged 45±7 years. Two structured interviews at the time of surgery and six months later were carried out to determine the characteristics of sexuality and communication within the couple. Results: In the two interviews, communication and the quality of sexual life were described as “good” in 72 and 77% of women, respectively (NS). The variables that had a 40% influence on the quaity of sexual life sixth months after surgery, were oophorectomy status, the presence of orgasm, the characteristics of communication and the basal sexuality with the couple. Conclusions: The sexuality of the hysterectomized women will depend, on a great extent, of pre-surgical variables. Therefore, it is important to consider these variables for the education of hysterectomized women
