Training machine learning models with synthetic data improves the prediction of ventricular origin in outflow tract ventricular arrhythmias
2022
In order to determine the site of origin (SOO) in outflow tract ventricular arrhythmias (OTVAs) before an ablation procedure, several algorithms based on manual identification of electrocardiogram (ECG) features, have been developed. However, the reported accuracy decreases when tested with different datasets. Machine learning algorithms can automatize the process and improve generalization, but their performance is hampered by the lack of large enough OTVA databases. We propose the use of detailed electrophysiological simulations of OTVAs to train a machine learning classification model to predict the ventricular origin of the SOO of ectopic beats. We generated a synthetic database of 12-l…

Muscle function in monozygotic female twin pairs discordant for hormone replacement therapy
2011
Introduction: Postmenopausal monozygotic twin pairs discordant for hormone replacement therapy (HRT) provide an advantageous study design controlling for genetic background for elucidating the relationships between aging, sex hormone levels, muscle strength, contractile capacity, and fatigability. Methods: Thirteen postmenopausal monozygotic twin pairs discordant for HRT were measured for maximal voluntary torque (MVC) and twitch characteristics using electrical stimulation before and after intermittent dynamic plantarflexor exercise until exhaustion. Results: Peak twitch torque was 32% higher in HRT users than in their non-HRT, genetically identical sisters (P = 0.002), but MVC did not dif…

Uno Studio di Caso sulla Flipped Classroom tra Università e Scuola
2017
Il contributo vuole presentare uno studio di caso sull'utilizzo della flipped classroom, svolto con 25 studenti del secondo anno del corso di laurea in Scienze della Formazione Primaria di Palermo, all'interno del Laboratorio di Tecnologie didattiche per la scuola Primaria e dell’Infanzia. La ricerca ha previsto una prima fase all'interno della quale è stato avviato un percorso formativo sulle modalità di progettazione di attività flipped con i 25 futuri insegnanti. Le attività, costruite a partire dai contenuti disciplinari di geografia, inglese ed arte sono state sperimentate durante la seconda fase della ricerca, all'interno di una quarta classe di una scuola primaria della provincia di …
Strategie innovative per la formazione dei futuri docenti
2017
La ricerca si propone di individuare un modello di acquisizione della competenza digitale e delle 4C (communication, collaboration, creativity and critical thinking) degli studenti del Corso di Laurea di Scienze della Formazione Primaria in vista di un reale sviluppo professionale. Si è ipotizzato che l’utilizzo del modello flipped classroom anche nella didattica universitaria possa rappresentare una valida proposta nella formazione dei futuri docenti di scuola primaria per la progressiva acquisizione delle 4C e che il progetto eTwinning nella formazione iniziale degli insegnanti possa fornire un valido supporto per promuovere tali competenze chiave. La valutazione e la scelta dei prodotti …
Type of Delivery, Neuropsychological Development and Intelligence in Twin Births
2019
Based on a retrospective cohort design with six-year-old children born in twin births, the relationship between verbal, non-verbal, global neuropsychological development, general intelligence and type of delivery has been studied. To this end, the possible effect of third gestational, obstetric and neonatal variables, such as maternal age at delivery, fetal presentation, gestational age, newborn weight and Apgar at minute one, was controlled. The exposed cohort includes children born by cesarean section, and the unexposed cohort is composed of children born vaginally with or without induction. A total of 124 children were evaluated in their first year of primary school using the Child Neuro…
Alcohol Consumption and Long-Term Labor Market Outcomes
2017
This paper examines whether alcohol consumption is related to long-term labor market outcomes. We use twin data for Finnish men and women matched to register-based individual information on employment and earnings. The twin data allow us to account for the shared environmental and genetic factors. The quantity of alcohol consumption was measured by weekly average consumption using self-reported data from three surveys (1975, 1981 and 1990). The average of an individual's employment months and earnings were measured in adulthood over the period 1990–2009. The models that account for the shared environmental and genetic factors reveal that former drinkers and heavy drinkers both have almost 2…

Leisure-time physical activity, body mass index, and waist circumreference : a longitudinal twin study from adolescence to adulthood
2010
ABSTRACT LEISURE-TIME PHYSICAL ACTIVITY, BODY MASS INDEX, AND WAIST CIRCUMFERENCE: A LONGITUDINAL TWIN STUDY FROM ADOLESCENCE TO ADULTHOOD Minna Kujala Master’s Thesis of Sport Medicine The University of Jyväskylä The Faculty of Sport and Health Sciences Department of Health Sciences 2010 Pages: 54, 8 appendixes The aim of this study was to investigate the effects of persistence and changes in the frequency of leisure- time physical activity on body mass index and waist circumference from adolescence to adulthood. Also, this study investigates the effect of the intensity of physical activity on body mass index (BMI) and waist circumference in adulthood. Participants in the study, members of…
