Abstract Aim: To assess in a subset of nationally representative sample Portuguese adolescents, the validity Body Mass Index (BMI) based on self‐reported weight and height. Methods: This study included 462 students grades 6, 8 10 (mean age 14.0 ± 1.9 years) from 12 public schools randomly selected list which took part 2006 Health Behaviour School Aged Children survey, corresponding to approximately 10% sample. Self‐reported height were recorded then measured. Results: Prevalence normal...
A prospective longitudinal cohort study was performed to assess the prevalence of iron deficiency in European infants at 12 mo age, and influence socio-economic status, dietary factors, growth morbidity on status. The consisted 488 normal term from primary healthcare centres 11 areas. Assessed were variables, intake, anthropometry regular intervals birth mo, haemoglobin, serum ferritin, mean corpuscular volume, transferrin saturation receptor concentrations age mo. anaemia 9.4%, 7.2%, 2.3%....
Intestinal parasites are responsible for morbidity in children worldwide, especially low income countries. In the present study we determine prevalence of intestinal and explore its association with anemia stunting school-aged children.A cross-sectional was conducted from September to October 2010 enrolling 328 attending primary school Lubango, second largest city after capital Luanda. Stool samples were collected parasite detection through microscopy molecular identification Entamoeba...
The correction for charge recombination was determined different plane-parallel ionization chambers exposed to clinical electron beams with low and high dose per pulse, respectively. energy nearly the same (about 7 9 MeV) any of used. Boag's two-voltage analysis (TVA) used determine ion losses, k(s), relevant each chamber considered. presence free electrons in air cavity accounted determining k(s) by TVA. determination made on basis models proposed past years Boag, Hochhäuser Balk account...
To identify psychosocial and lifestyle indicators including alcohol consumption, that may distinguish overweight obese adolescents from their peers, align them with other chronic conditions.The sample included 6 131 6th, 8th, 10th grade public school Portuguese students, aged 11-16 years, who participated in the Health Behavior School-Aged Children (HBSC)/WHO survey of adolescent health. Body mass index (BMI) was based on self reported weight height. Separate analyses behavioral variables...
Lysosomal acid lipase deficiency (LALD) is an autosomal recessive disorder and unrecognized cause of dyslipidemia. Patients usually present with dyslipidemia altered liver function mutations in LIPA gene are the underlying LALD.The aim this study was to investigate LALD individuals severe and/or steatosis.Coding, splice regions, promoter region were sequenced by Sanger sequencing a cohort mutation-negative familial hypercholesterolemia (FH) patients (n = 492) population sample comprising...
This study examined the association of family and maternal characteristics with preschool children's dietary patterns. Trained interviewers evaluated subsample 3422 mothers children enrolled in population-based birth cohort Generation XXI (Porto, Portugal, 2005-2006). Maternal behaviours (exercise, smoking habits, diet child-feeding practices) were evaluated. was classified by a score, patterns identified latent class analysis. Odds ratios (OR) confidence intervals (95% CI) estimated...
The World Health Organization promotes salt iodisation to control iodine deficiency. In Portugal, the use of iodised in school canteens has been mandatory since 2013. present study aimed evaluate status school-aged children (6-12 years) and monitor canteens. A total 2018 participants were randomly selected participate a cross-sectional survey northern Portugal. Children's urine samples from households collected. lifestyle questionnaire was completed by parents assess children's eating...
Oxidative stress and nitric oxide (NO) appear to represent important links between obesity cardiovascular, metabolic and/or renal disease. We investigated whether oxidative NO production/metabolism are increased in overweight obese prepubertal children correlate with cardiometabolic risk function. performed a cross-sectional evaluation of 313 aged 8-9 years. Anthropometrics, 24-h ambulatory blood pressure, pulse wave velocity (PWV), insulin resistance (homoeostasis model assessment index...

Energy and angular distributions of electron beams with different energies were simulated by Monte Carlo calculations. These generated the NOVAC7® system (Hitesys, Italy), a mobile accelerator specifically dedicated to intra-operative radiation therapy (IORT). The beam simulations verified comparing measured dose corresponding calculated distributions. As expected, considerable difference was observed in energy between IORT studied present work produced conventional accelerators for non-IORT...
Background: Handgrip strength (HGS) is a useful indicator of nutrition status in adults, but evidence lacking pediatric patients. The aim this study was to describe the association between undernutrition and HGS patients at hospital admission, quantifying modifying effect disease severity, anthropometrics, other patient characteristics on HGS. Materials Methods : Eighty‐nine inpatients aged ≥6 years consecutively admitted were recruited longitudinal study. Nutrition evaluated using body mass...
Fatty acid (FA) composition varies over the course of day and during lactation. The aim this study was to evaluate FA its compositional stability in human milk, from 7 week 16 lactation.Human milk collected all feedings 24 h at weeks 4, 8, 12 lactation 31 lactating women. FAs were analyzed through gas chromatography. Comparisons made with analysis variance.Total monounsaturated decreased 33.04 +/- 2.58% wt/wt 31.48 3.32% lactation, much expenses decrease major found oleic acid. Main...
A chemical vapour deposition diamond detector fabricated at Rome 'Tor Vergata' University was investigated for its applicability as transfer dosimeter in radiotherapy photon beams with small field sizes. The consists of a single crystal very sensitive volume (0.004 mm3). showed measurement repeatability 0.1% and long term reproducibility 0.4%. Monte Carlo simulations revealed response dependence on the beam energy about 2% from 60Co quality to 10 MV beam. calculated found be independent size...
Birth is an event that exposes the newborn baby to a high concentration of free radicals (reactive oxygen species (ROS)/reactive nitrogen (RNS)), which can contribute several diseases. The balanced equilibrium between ROS/RNS and antioxidant system key factor in preventing plethora involves endogenous exogenous molecules, from vitamins (A, E, C) enzymes (glutathione peroxidase, superoxide dismutase), metals (copper, zinc, selenium) other molecules (coenzyme Q10, melatonin) act synergistic...
The present study aimed to evaluate the association of 4-year-old children's dietary patterns with adiposity at 7 years, according child's sex, using a conceptual model.Prospective cohort study. Diet was assessed an FFQ. Age- and sex-specific BMI standard deviation scores (Z-scores) were defined WHO. Fat mass percentage (FM%), fat index (FMI) waist-to-height ratio (WHtR) also considered, converted into Z-scores means deviations current sample. Dietary identified by latent class analysis...
