Psychological determinants of the effectiveness of conjugated linoleic acid supplementation in overweight and obese women-a randomized controlled trial.

Introduction: Previous studies investigating the effectiveness of conjugated linoleic acid (CLA) supplementation in body weight reduction provided unequivocal results. We hypothesized that psychological factors such as self-efficacy, locus of control or dispositional optimism can affect the success of the intervention. Therefore, this study aimed to determine the psychological factors that modulate the effectiveness of CLA supplementation in overweight or obese women and affect the ability to successfully complete the study.

Do children with asymptomatic ventricular preexcitation have similar quality of life as healthy children?

Background: To our knowledge, no studies have assessed quality of life (QoL) in asymptomatic children with a preexcitation electrocardiogram pattern.

Aim: To evaluate the QoL of children with asymptomatic Wolff-Parkinson-White (WPW) syndrome.

Methods: This study involved QoL assessment of 31 children with asymptomatic preexcitation and 82 healthy children using the WHOQOL-BREF and the Pediatric Arrhythmia Related Score (PARS), a specific questionnaire that we have developed, which is related to patients' feelings and observations concerning arrhythmia.

Subjective Psychophysical Experiences in the Course of Inflammatory Bowel Disease-A Comparative Analysis Based on the Polish Pediatric Crohn's and Colitis Cohort (POCOCO).

No gold standard is available to evaluate subjective psychophysical experiences in pediatric inflammatory bowel disease (IBD). We aimed to assess pain, anxiety, and limitations in social activities at diagnosis and the worst flare of the disease in relation to clinical expression, treatment and IBD severity. A total of 376 children completed the survey (Crohn's disease (CD) n = 196; ulcerative colitis (UC) n = 180).

Overweight in classical phenylketonuria children: A retrospective cohort study.

Purpose: This cohort study aimed to determine the frequency of overweight and obesity in classical phenylketonuria children and to identify the possible influence of metabolic control on the BMI of the studied patients.

Patients And Methods: The study group included 63 classical phenylketonuria patients (40 girls and 23 boys; aged 5-16 years). Their z-score BMI, metabolic control, educational level of parents and socioeconomic status were determined.
