    (Universidad de Murcia. Servicio de Publicaciones, 2002) Miguel Díaz, Mario de; Apodaca Urquijo, Pedro Miguel; Arias Blanco, José Miguel; Escudero Escorza, Tomás; Rodriguez Espinar, Sebastián; Vidal García, Javier
    In this paper, we analyze the performance of university students who have followed two different models of secondary education in Spain (COU and LOGSE). In order to do that, we have followed up a sample of cohorts from first year at university in 5 Spanish universities: Barcelona, Oviedo, País Vasco, Salamanca and Zaragoza. That means that we have analyzed data from almost 150.000 students along 2 to 6 years. We have used descriptive and comparative statistics, bivariate and multivariate, and also some meta-analysis. Our main conclusion is that there are no significant differences in the performance of students at university depending on the type of secondary education they have followed.

    (Mary Ann Liebert, Inc., 2018) Ortega-García, Juan A.; Kloosterman, Nicole; Alvarez, Lizbeth; Tobarra-Sánchez, Esther; Cárceles-Álvarez, Alberto; Pastor-Valero, Rebeca; López-Hernández, Fernando A.; Sánchez-Solís, Manuel; Claudio, Luz; Cirugía, Pediatría y Obstetricia y Ginecología
    Background: Obesity is a major public health crisis among both children and adults and contributes to significant physical, psychological, and economic burden. We aim to investigate the effect of duration of breastfeeding on excessive weight and obesity at 6 years of age. Subjects/methods: Data on breastfeeding and child anthropometric measurements were collected in a birth-cohort study in Murcia, Spain (n = 350). Breastfeeding status and body mass index (BMI) were established according to WHO definitions. Other factors potentially related to children's weight were considered. Multiple log-linear and ordinal regressions were used to analyze the effects of breastfeeding on overweight and obesity when considering potential confounders. Results: 33% and 17.3% of children in the study were of excess weight and obesity, respectively. Univariate predictors of BMI in children aged 6 were as follows: pregestational maternal BMI (kg/m2) (R2 = 0.127, p < 0.01); full breastfeeding (weeks) R2 = -0.035, p < 0.01); infant weight gain (kg) (R2 = 0.348, p < 0.01); and maternal alcohol consumption during pregnancy (g/day) (R2 = 0.266, p < 0.01) at age 6. In the ordinal logistic regression, full breastfeeding was associated with a significant decrease in obesity -0.052 (95% CI, -0.10 to -0.003). Conclusions: The delay of bottle feeding introduction may have a protective effect against obesity at 6 years of age. Our findings reinforce the need for greater support of breastfeeding and to promote a healthy environment and antipoverty interventions during pregnancy and infancy, alongside other strategies for obesity prevention.

    (Universidad de Murcia. Servicio de publicaciones, 2024) Santos, Taynara Silva dos; Anacleto, Jessica Candido; Spinazola Cesar, Vitor; Lino, Rafael Luis Bressani; Lino, Amanda de Assunção; Garbuio, Danielle
    Objetivo: El estudio tuvo como objetivo caracterizar la flebitis en adultos en un sector de hospitalización clínica, en cuanto a incidencia, grado y factores relacionados. Metodología: Se trata de una cohorte realizada en un sector de hospitalización clínica de un hospital terciario filantrópico en el interior del estado de São Paulo, Brasil. El estudio incluyó a adultos mayores de 18 años, hospitalizados y con acceso venoso periférico; la invitación se realizó a cada paciente en su primer día de hospitalización y quienes aceptaron firmaron el formulario de consentimiento libre informado (FCLI), fueron incluidos y evaluados diariamente para detectar la aparición de flebitis, así como sus características. Participaron de la investigación 49 personas, con una edad promedio de 61,29 años (de: 20.692), la mayoría mujeres (69,39%), blancas (65,30%). Resultados: La incidencia de flebitis fue del 28,56%; la edad mayor de 60 años (p=0,004) y el uso de anticoagulantes (p=0,025) aumentaron el riesgo de desarrollar flebitis. El uso de antiinflamatorios intravenosos (p=0,008) resultó ser un factor que redujo el número de flebitis. Conclusión: Se concluye que la incidencia de flebitis estuvo relacionada con factores como edad, uso de anticoagulantes; Los medicamentos antiinflamatorios intravenosos parecen ser un factor protector.
