A simple high-performance liquid chromatography (HPLC) method for the measurement of pyridoxal-5-phosphate and 4-pyridoxic acid in human plasma.

2014

Abstract Background Low concentration of plasma pyridoxal-5-phosphate (PLP) is associated with hyperhomocysteinemia and inflammation. Most methods for the measurement of plasma PLP require large specimen volume and involve the use of toxic reagents. Methods We have developed a HPLC method for the measurement of PLP and 4-pyridoxic acid (4-PA) in plasma, which requires small specimen volume. The samples are prepared without adding any toxic reagents. Furthermore, we have examined whether intake of vitamin B 6 affects the concentration of plasma PLP and 4-PA. Results The coefficient of variation of the method was 6% and the recovery of the added vitamin in plasma was about 100%. The concentra…

Long-term effects of the home literacy environment on reading development: Familial risk for dyslexia as a moderator.

2021

This study aimed to gain better understanding of the associations between literacy activities at home and long-term language and literacy development. We extended the home literacy environment (HLE) model of Sénéchal and LeFevre (Child Development [2002], Vol. 73, pp. 445–460) by including repeated assessments of shared reading, oral language, and reading comprehension development, including examination of familial risk for dyslexia as a moderator, and following development over time from ages 2 to 15 years. Of the 198 Finnish participants, 106 have familial risk for dyslexia due to parental dyslexia. Our path models include development in vocabulary (2–5.5 years), emerging literacy (5.5 ye…

A METHODOLOGY DEVELOPMENT FOR A WEB-BASED SURVEILLANCE SYSTEM OF ADOLESCENT FOOD HABITS AND LIFESTYLES – THE ASSO PROJECT

2012

ASSO Project (Adolescents Surveillance System and Obesity prevention) is a study financed by the Italian Ministry of Health, aimed at developing an innovative web-based system for a standardized collection of data on food consumptions, lifestyles and body size in the adolescents attending high schools. One of the main objectives of the project is to develop user-friendly and cost-effective tools to create a web-based software. A Systematic Literature Review (SLR) on the most valid dietary and physical activity/fitness assessment methods used in the target population has been perfomed. The implementation of the software is being done by using JAVA and the data archive system is based on MySQ…

Birth weight, cardiometabolic risk factors and effect modification of physical activity in children and adolescents: pooled data from 12 internationa…

2020

Abstract Objectives Low and high birth weight is associated with higher levels of cardiometabolic risk factors and adiposity in children and adolescents, and increases the risk of cardiovascular diseases, obesity, and early mortality later in life. Moderate-to-vigorous physical activity (MVPA) is associated with lower cardiometabolic risk factors and may mitigate the detrimental consequences of high or low birth weight. Thus, we examined whether MVPA modified the associations between birth weight and cardiometabolic risk factors in children and adolescents. Methods We used pooled individual data from 12 cohort- or cross-sectional studies including 9,100 children and adolescents. Birth weigh…

Somatic Symptoms among Children and Adolescents in Poland: A Confirmatory Factor Analytic Study of the Children Somatization Inventory.

2013

The aim of the present study was to examine the factor structure and psychometric properties of the short version of the Children’s Somatization Inventory (CSI-24) in Poland. The CSI-24 is a self-report questionnaire designed to assess somatic symptoms in children and adolescents. A total of 733 children and adolescents, aged 12 to 17 years, participated in this research. The participants for this study were recruited from urban and suburban schools of Opole province in South Western Poland. In addition to the CSI-24, all participants completed the Spence Children’s Anxiety Scale (SCAS) and the Strength and Difficulties Questionnaire (SDQ). The bifactor model that included the three domain-…

Adolescenti e stile “Young Adult”

2021

Molto spesso dimentichiamo quello che significa essere adolescenti. Molto spesso dimentichiamo quello che è uno degli aspetti più importanti della letteratura: arrivare a toccare le corde dell’animo e del cuore dei lettori, in un modo che allo stesso tempo intrattiene e gli permette di sentirsi compresi e meno soli, di sentirsi umani. L'adolescenza è la terra dei contrasti, delle grandi emozioni vissute e la letteratura può svolgere una funzione utile aiutando gli adolescenti a sentirsi meno soli. Leggere richiede coraggio, perché accogliere qualcosa, riconoscerla, significa mettersi in gioco personalmente. Il libro offre all’adolescente una visione di sé, non solo “qui ed ora”, ma dona una…

Parental and Familial Factors Influencing Physical Activity Levels in Early Adolescence: A Prospective Study

2020

Parental/familial factors are important determinants of the physical activity level (PAL) in children and adolescents, but studies rarely prospectively evaluate their relationships. This study aimed to evaluate the changes in physical activity levels among adolescents from Bosnia and Herzegovina over a two-year period and to determine parental/familial predictors of PAL in early adolescence. A total of 651 participants (50.3% females) were tested at baseline (beginning of high school education
