Tratamiento quirúrgico de la enfermedad por reflujo gastroesofágico. Valoración de resultados y estado actual de las indicaciones

2015

1. PLANTEAMIENTO DEL PROBLEMA La Enfermedad por Reflujo Gastro-Esofágico (ERGE) constituye una entidad de elevada prevalencia en la población general (7’7 %). Su tratamiento desde que Nissen realizara en 1956 la primera funduplicatura, ha sufrido muchos vaivenes, debido a la aparición de fármacos antisecretores cada vez de mayor potencia, a los efectos inherentes de la cirugía (disfagia, atrapamiento aereo, imposibilidad de eructar / vomitar), y a la aparición de la funduplicatura laparoscópica (Dallemagne 1992) que supuso un cambio explosivo a favor del tratamiento quirúrgico. No obstante, a partir de 2005, tras una década de funduplicatura laparoscópica, y tras millares de enfermos interv…

Estimation of sparse generalized linear models: the dglars package

2013

dglars is a public available R package that implements the method proposed in Augugliaro, Mineo and Wit (2013) developed to study the sparse structure of a generalized linear model. This method, called dgLARS, is based on a differential geometrical extension of the least angle regression method (LARS). The core of the dglars package consists of two algorithms implemented in Fortran 90 to efficiently compute the solution curve; specifically a predictor-corrector algorithm and a cyclic coordinate descent algorithm.

The home literacy model in a highly transparent orthography

2019

We investigated the extent to which home literacy activities during the preschool year would predict the development of children’s language and literacy skills in primary school, in a highly transparent Finnish language. Also, the correlates of maternal literacy activities during preschool were examined. Literacy and language skills of 1,880 children (6-year-olds at the baseline) were tested at 5 time points from the beginning of preschool to the end of Year 2; mothers filled in questionnaires at the end of preschool. The results showed that home teaching of reading at preschool age predicted children’s emergent literacy (letter knowledge, word reading fluency) in primary school, while shar…

To Help or Not to Help? Prosocial Behavior, Its Association With Well-Being, and Predictors of Prosocial Behavior During the Coronavirus Disease Pand…

2022

The coronavirus disease (COVID-19) pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants (N = 9,496) from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior was reported to occur frequently. Multi…

The feasibility of working memory tablet tasks in predicting scholastic skills in classroom settings

2019

Cognitive assessment in natural group settings facilitates data collection but poses threats to the validity. In this study, tablet‐based working memory (WM) tasks, the counting span, and reading span were used in predicting 12‐year‐old children's (N = 837) scholastic skills and fluid intelligence in a classroom with environmental noise. WM tasks had excellent internal consistency, correlated with scholastic skills, and accounted for more of the variance in cognitive performance (grade point average, fluid intelligence, scholastic skills) compared with individually administered (n = 190) digit span task. Furthermore, the multilevel analysis revealed that compared with the classrooms with no…

Cognitive predictors of counting skills

2018

Rote counting skills have found to be a strong predictor of later arithmetic and reading fluency. However, knowledge of the underlying cognitive factors influencing counting skill is very limited. Present study examined to what extent language skills (phonology, vocabulary, and morphology), nonverbal reasoning skills, and memory at the age of five could explain counting skill at the beginning of first grade. Gender, parents’ education level and child’s persistence were included as control variables. The question was examined in a longitudinal sample (N = 101) with a structural equation model. Results showed that language skills together with memory, nonverbal reasoning skills and parent’s e…

In Search of Determinants of Time-Discounting in Monetary Choices : Personal Characteristics Matter Only a Little

2022

Time-discounting in monetary choices is determined by aspects related to the reward, contextual factors and characteristics of a person. In the present study, we used three datasets (Ndata1 = 419; Ndata2 = 485; Ndata3 = 240) to examine how well personal characteristics (sociodemographic, financial situation, self-control, cognitive abilities, negative experiencing, and trustfulness) predict time-discounting in both hypothetical and real reward scenarios. The results of the regression analyses indicate that the characteristics of a person only explain a small proportion of the variance in time-discounting (R2 ranged from .10 to .19). The only substantive predictors of time-discounting in mon…

Predictors of outcome after a time-limited psychosocial intervention for adolescent depression.

2022

Research on the predictors of outcome for early, community-based, and time-limited interventions targeted for clinical depression in adolescents is still scarce. We examined the role of demographic, psychosocial, and clinical variables as predictors of outcome in a trial conducted in Finnish school health and welfare services to identify factors associating to symptom reduction and remission after a brief depression treatment. A total of 55 12–16-year-olds with mild to moderate depression received six sessions of either interpersonal counseling for adolescents (IPC-A) or brief psychosocial support (BPS). Both interventions resulted in clinical improvement at end of treatment and 3- and 6-mo…

Best friends in adolescence show similar educational careers in early adulthood

2012

The present study investigated the role of best friends in educational career development from adolescence to adulthood. Participants' (N = 476) reciprocal best friendships were identified at age 15, while their educational attainment was investigated in early adulthood (age 26), their intelligence (IQ) at age 13, and parental education, educational expectations and academic achievement at age 16. The results revealed that adolescent best friends ended up pursuing similar educational careers in adulthood. Furthermore, three kinds of partner-effects were found when adolescents' prior career behaviors were controlled for: (1) best friends' intelligence predicted adolescents' later academic pe…
