Prenatal Air Pollution and Reduced Birth Weight: Decline in Placental Mitochondria as a Potential Mechanism.
2016
Strong epidemiological evidence links prenatal exposure to ambient air pollution and outcomes including low birth weight, intrauterine growth restriction, and preterm birth.1,2 A new study finds evidence that the association between prenatal air pollution exposure and reduced birth weight may be mediated in part by a decline in the mitochondrial content of the placenta.3 During pregnancy, the placenta supports the nourishment, growth, and development of the fetus, and mitochondria within the cells of the placenta are essential to these processes.4 Mitochondria, the cellular organelles that regulate energy production, are easily damaged by reactive oxygen species generated by oxidative stres…
Effect of dietary interventions during weaning period on parental practice and lipoproteins and vitamin D status in two-year-old children
2016
ABSTRACT Objective: Evaluate if a two-day course for parents on nutrition and applied baby food preparation had an effect on child’s intake of home-made foods, lipid concentration, and vitamin D status. Design: Randomized controlled trial at age 6 months and follow-up at ages 15 and 24 months. Setting: Four health care clinics in Kristiansand, Norway. Subjects: Thirty-nine pairs of 6-month-old children and their parents in the intervention group and 20 pairs in the control group. Results: At age 15 months, the intervention group had lower intakes of ready-made porridge (2.0 vs. 5.8 servings per week (p < 0.05)), lower intake of canned baby food (2.9 vs. 6.3 servings per week (p < 0.05)) and…
Dental status, salivary flow, and sociodemographic aspects in Sheehan Syndrome patients
2018
Background Sheehan’s syndrome (SS) is one of the leading causes of hypopituitarism in developing countries. It occurs after postpartum necrosis of the pituitary gland, and it is considered a significant public health problem. This paper, apparently unpublished, aimed to perform an analysis on oral aspects in patients with SS. Material and Methods A cross-sectional study was performed with 23 women diagnosed with SS at the Division of Endocrinology and Diabetes (Walter Cantídio University Hospital, Fortaleza, Brazil). Results Data on sociodemographic, dental and salivary flow aspects were collected through a clinical approach and a panoramic radiograph request. The mean age was 64 ± 11.5 yea…
Actual and perceived weight status and its association with slimming and energy-balance related behaviours in 10- to 12-year-old European children: t…
2016
Both parents' and children's perception of children's weight status may be important predictors of slimming and energy-balance related behaviours, independent of children's actual weight status.; We examined the cross-sectional association of children's self-reported slimming and energy-balance related behaviours with children's (i) actual, (ii) self-perceived and (iii) parent-perceived weight status.; Data of 10- to 12-year-old European children and their parents were used. Multilevel logistic and linear regression analyses were performed, adjusting for age, gender, parental weight controlling behaviours, education, marital status and ethnicity.; Independent of their actual weight status, …
Population pharmacokinetic meta-analysis of individual data to design the first randomized efficacy trial of vancomycin in neonates and young infants.
2019
Abstract Objectives In the absence of consensus, the present meta-analysis was performed to determine an optimal dosing regimen of vancomycin for neonates. Methods A ‘meta-model’ with 4894 concentrations from 1631 neonates was built using NONMEM, and Monte Carlo simulations were performed to design an optimal intermittent infusion, aiming to reach a target AUC0–24 of 400 mg·h/L at steady-state in at least 80% of neonates. Results A two-compartment model best fitted the data. Current weight, postmenstrual age (PMA) and serum creatinine were the significant covariates for CL. After model validation, simulations showed that a loading dose (25 mg/kg) and a maintenance dose (15 mg/kg q12h if <…
A meta-analysis of the validity of FFQ targeted to adolescents.
2015
AbstractObjectiveThe present work is aimed at meta-analysing validity studies of FFQ for adolescents, to investigate their overall accuracy and variables that can affect it negatively.DesignA meta-analysis of sixteen original articles was performed within the ASSO Project (Adolescents and Surveillance System in the Obesity prevention).SettingThe articles assessed the validity of FFQ for adolescents, compared with food records or 24 h recalls, with regard to energy and nutrient intakes.SubjectsPearson’s or Spearman’s correlation coefficients, means/standard deviations, kappa agreement, percentiles and mean differences/limits of agreement (Bland–Altman method) were extracted. Pooled estimates…
Towards a Unified Functional Trait Framework for Parasites
2019
Trait-based research holds high potential to unveil ecological and evolutionary processes. Functional traits are fitness-related characteristics of individuals, which are measured at individual level and defined without using information external to the individual. Despite the usefulness of the functional approach to understand the performance of individuals in ecosystems, and parasitism being the most common life-history strategy on Earth, studies based on functional traits of parasites are still scarce. Since the choice of functional traits is a critical step for any study, we propose a core list of seven functional traits of metazoan parasites, related to three universal challenges faced…

The ascidian Styela plicata hemocytes as a potential biomarker of marine pollution: In vitro effects of seawater and organic mercury.
2017
Toxic metals, such as mercury, contribute substantially to anthropogenic pollution in many estuarine environments. Animals living in those environments, particularly invertebrate filter feeders like tunicates, can be used as bioindicators. In an attempt to identify cellular markers for revealing pollution, this study examined in vitro the effects of different concentrations of methyl mercury on Styela plicata hemocytes. The harvested hemocytes from S. plicata that were exposed to the metal had a significant mortality, cellular count and morphometric alterations. These findings provided evidence of MeHg immunotoxic effects on S. plicata, resulting in hemocyte death and morphological changes …
Understanding illnesses through a film festival: an observational study
2019
Abstract Audio-visual materials play a fundamental role in the context of education, care and clinical treatment, as they seem to have a high impact on public awareness. This study aims to describe what messages are perceived by the society at an International Festival of Short Films and Art on Diseases that may help to understand difficult topics, such as illness, dying and suffering. Through an observational, descriptive, cross-sectional study, using full participant observation and an open, self-administered questionnaire, 32 short films were analysed during a healthcare art festival. Categories were developed using inductive content analysis. The message perceived by the participants, a…
