The study aimed to describe trajectories of free sugar (FS) intake, its main sources and the associations with socio-economic status (SES) in Portuguese children/adolescents evaluated at 4, 7, 10 and 13 years of age from Generation XXI birth-cohort. Dietary intake was assessed through 3-day food diaries ( 5268). Added sugar intake was estimated following a systematic methodology, and FS was based on the WHO definition.

Patterns of ultra-processed foods consumption throughout childhood and trajectories of growth and adiposity.

Background & Aims: Ultra-processed foods (UPF) consumption has been associated with unhealthy outcomes. However, the literature lacks robust longitudinal studies considering its cumulative effect, particularly in young populations. This study aimed to evaluate the relationship between UPF consumption patterns throughout childhood with growth and adiposity trajectories.

MULT: An allometric body mass index (ABMI) reference to assess nutritional status of multiethnic children and adolescents.

Objectives: To develop an allometric body mass index (ABMI) reference that adjusts the weight in relation to height, taking into account the changes during development (MULT ABMI reference), and to compare it with international BMI references.

Methods: The MULT ABMI reference was constructed through the LMS method, calculated with 65 644 ABMI observations of 17 447 subjects aged 5-22 years, from the United Kingdom, Ethiopia, India, Peru, Vietnam, Portugal, and Brazil. The M, S, and L curves of the MULT ABMI reference were compared with the curves of the MULT, World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF), and Dutch Growth Study (DUTCH).

The final dataset, gathering data from the national registry database, consisted of 278,116 dogs with confirmed deaths. The mean lifespan at birth for all the dogs was around 8.

Pars-plana vitrectomy for the treatment of vitreous amyloid in patients with hereditary transthyretin amyloidosis.

Purpose: To describe a series of patients with hereditary transthyretin amyloidosis (ATTRv) with vitreous amyloid and to study the efficacy and safety of pars plana vitrectomy (PPV) for its treatment.

Methods: Retrospective study of 266 patients with ATTRv due to Val30Met mutation submitted to PPV for vitreous amyloid, with a minimum 3-month follow-up. Indications for surgery were disabling myodesopsia or 2 lines loss in visual acuity.

The Interaction Effect of Adverse Childhood Experiences and Socioeconomic Circumstances in Adolescent Depressive Symptomatology.

Purpose: Limited research has examined the combined effects of psychosocial and material adversities experienced in childhood during adolescence, a sensitive period of rapid social, emotional, and cognitive development. We investigated the interaction effect of adverse childhood experiences (ACEs) and socioeconomic circumstances (SECs) during childhood on emerging self-reported depressive symptomatology among 13-year-old Portuguese adolescents.

Methods: We utilized data from 4,280 participants in the Generation XXI birth cohort, collected during the baseline (2005-2006), third (2016-2017), and fourth waves (2018-2020).

Association between bisphenol A exposure and cardiometabolic outcomes: A longitudinal approach.

Increased cardiometabolic risk is associated with abnormalities in blood biomarkers profile and adiposity measurements. Some substances found in the food matrix and the environment, called endocrine-disrupting chemicals, may impair cardiometabolic health in the early and later stages of life. Bisphenol A (BPA) is a food contaminant that migrates from food contact materials and may act as an endocrine disruptor, negatively affecting human health.

Eating out of home in Portugal: characterisation and effects on dietary intake.

This cross-sectional study aims to describe and compare energy, nutrient intake and food consumption according to eating location and by age groups using data from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015/2016). Dietary intake was estimated by two non-consecutive days of food diaries (children)/24-h recalls (other age groups), and four eating location categories were defined according to the proportion of meals consumed at out-of-home locations: (at least 80 % of meals at home), , and . The majority of meals (69·1 %) were consumed at home.

The relationship between social capital and inflammatory biomarkers in early adulthood: A longitudinal study.

Higher levels of social capital (SC) are associated with better health status. However, there is little evidence of the impact of SC on biological health outcomes in the early ages. To identify the association between SC in adolescence and inflammation levels in early adulthood.

Effects of the AMPAR Antagonist, Perampanel, on Cognitive Function in Rats Exposed to Neonatal Iron Overload.

Iron accumulation has been associated with the pathogenesis of neurodegenerative diseases and memory decline. As previously described by our research group, iron overload in the neonatal period induces persistent memory deficits and increases oxidative stress and apoptotic markers. The neuronal insult caused by iron excess generates an energetic imbalance that can alter glutamate concentrations and thus trigger excitotoxicity.

Early feeding and nutritional status of Portuguese children in the first 36 months of life: EPACI Portugal 2012-a national representative cross-sectional study.

Background: Early feeding practices have a critical role in the future not only in health but also in modulating eating habits. This study aimed to assess breastfeeding and complementary feeding practices and the nutritional status of Portuguese toddlers aged 0-36 months.

Methods: EPACI Portugal 2012 is a cross-sectional study of a national representative sample.

Development and validation of a photograph-based instrument to assess nutrition literacy: The NUTLY project.

Most instruments measuring nutrition literacy evaluate theoretical knowledge, not necessarily reflecting skills relevant to food choices. We aimed to develop and validate a photograph-based instrument to assess nutrition literacy (NUTLY) among adults in Portugal. NUTLY assesses the ability to distinguish foods with different nutritional profiles; from each of several combinations of three photographs (two foods with similar contents and one with higher content) participants are asked to identify the food with the highest energy/sodium content.

Obstetric Interventions Among Native and Migrant Women: The (Over)use of Episiotomy in Portugal.

Episiotomy, defined as the incision of the perineum to enlarge the vaginal opening during childbirth, is one of the most commonly performed surgical interventions in the world. We aimed to determine if migrant status is associated with episiotomy, and if individual characteristics mediate this association. We analyzed data from the Bambino study, a national, prospective cohort of migrant and native women giving birth at a public hospital in mainland Portugal between 2017 and 2019.

Longitudinal tracking of diet quality from childhood to adolescence: The Interplay of individual and sociodemographic factors.

This study aimed to examine diet tracking from childhood to adolescence, using 4 time-points, and the influence of socioeconomic and individual characteristics in this transition. The sample included 6893 children from the Portuguese birth cohort Generation XXI with complete information on Food Frequency Questionnaire in at least one of the considered follow-ups. A Healthy Eating Index (HEI), previously developed to assess adherence to WHO's dietary recommendations, was applied at all ages (4, 7, 10 and 13y).
