  • Antimicrobial and antioxidant activities of natural compounds: enhance the safety and quality of food
    Publication . Faleiro, Maria Leonor; Miguel, Maria da Graça
    Nature has offered us a tremendous diversity of natural compounds, for which antimicrobial and antioxidant properties have been intensively explored and nowadays are plenty recognized. During the last decades both the antimicrobial action of natural compounds (preventing and limiting microbial growth) and their antioxidant properties (reducing the oxidation of fats and limiting the ripening and browning of fruit and vegetables after harvesting) have been intensively investigated, particularly in the food packaging sector, evidencing that they may represent an effective eco-friendly approach to enhance the safety and quality of food products, without an environmentally deleterious impact.

  • Food insecurity in higher education students
    Publication . Paula, Aline de; Carneiro, Beatriz; Mendes, Inês; Pacheco, Mariana; Gonçalves, Marta; Pinto, Ezequiel; Palma Mateus, Maria
    Food insecurity (FI) indicates a situation in which there is no regular access to food in satisfactory quantity and quality. To characterize FI in students from Portuguese higher education institutions, a study was conducted in a non-random sample of students, with an online questionnaire consisting of sociodemographic questions and the Portuguese version of the IF scale. There were 200 valid questionnaires and 27.5% of the participants were classified as having some degree of FI. Participants with FI reported fewer visits to the family’s home (p = 0.024) and less financial resources (p < 0.001). The results indicate that interventions are needed in this area.

  • Metabolism and the impact of protein intake in chronic critically ill adult patients: protocol for a unicentric prospective cohort study (MetaChronic Study)
    Publication . Castro, Sílvia; Granja, Cristina; Dionne, Joanna C.; Pires, Teresa; Oliveira, Carolina; Binnie, Alexandra
    Background: Survival of acutely critically ill patients has improved, resulting in a growing population of chronic critically ill (CCI) patients with prolonged organ dysfunction, mechanical ventilation, and high morbidity. While nutritional guidelines during the acute phase of critical illness are well defined, our understanding of metabolism and nutritional needs in CCI patients is limited. Persistent inflammation may influence the metabolic response and nutritional uptake, highlighting the need for prospective studies in this area. Methods: The MetaChronic Study is a single-center, prospective cohort study of metabolism in patients with CCI. Adult ICU patients with invasive mechanical ventilation ≥48 h and ICU stay >7 days are eligible. Patients are followed for up to 42 days after ICU admission, with final outcomes assessed at 90 days. Resting energy expenditure is measured weekly by serial indirect calorimetry. Weekly protein and calorie intake are recorded and inflammation is assessed using serum C-reactive protein and procalcitonin measurements. Patients are categorized according to high or low protein intake (>1.3 g/kg/ day vs. ≤1.3 g/kg/day after the first week). The primary objective is to characterize longitudinal metabolic trajectories. Secondary objectives include subgroup analyses (septic, trauma, neurocritical patients), assessment of the interaction between inflammation and metabolic rate, and exploratory analyses of the association between protein intake and clinical outcomes. Ethics and dissemination: The study has been approved by the institutional ethics committee. Findings will be disseminated through peer-reviewed journals and scientific conferences.
