- Breastfeeding practices, appetite regulation and growth in healthy children in preschoolPublication . Soares, Daniela; Moura, Daniela; Reis, Lucinda; Soares, Sara; Almeida-de-Souza, JulianaBackground Breastfeeding shapes food intake in children, through previous experience of basic flavors derived from the maternal diet by intrauterine life, by breast milk and also by the experience during the first year of life (Vereijken et al. 2011). In food choices, children only consider their preferences, based on known basic flavors, and these same preferences are now involved in appetite regulation (Faith et al. 2004). Developing the necessary skills to make safe and nutritious choices is undoubtedly a fundamental achievement that supports healthy growth. (Vereijken et al., 2011). Objective Evaluate the association between breastfeeding practices, the Appetite Regulation and Healthy Growth in children between 3 and 5 years old. Methodology A total of 327 children aged between 3 and 5 years old, living in the city of Braganza-Portugal and who attend kindergartens, were included in the sample. Two questionnaire were filled by parents of children: (1) A questionnaire regarding the regulation of appetite, Child Eating Behaviour Questionnaire-CEBQ (Wardle et al. 2001). adapted to Portugal (Viana et al. 2008), which includes eight scales: Food responsiveness—FR, Emotional over-eating—EOE, Enjoyment of food–EF, Desire to drink—DD, Satiety responsiveness—SR, Slowness in eating—SE, Emotional under-eating—EUE, Food fussiness— FF. (2) A Question about breastfeeding practices in the period of 0–6 months to identify if the child was exclusively breastfed or not. Finally we proceeded the anthropometric measurements (weight, height and calculate BMI) of children and them BMI were categorized according to CDC recommendations (Kuczmarski RJ et al. 2002). Statistical analysis was performed using the SPSS version 20.0 using the Kruskal–Wallis test (F) and Mann–Whitney-Wilcoxon test (Z). Results The sample mean age was 4 ± 0.8 years old. Children were mostly girls (51.7 %) and having been breastfed minority (43.7 %). A relation was found between breastfeeding practices and the score of one of from CEBQ scales (DD): FR(F = -0.185, p = 0.912), EOE(F = 2.436, p = 0.296), RS(F = 1.437, p = 0.488), SE(F = -0.463, p = 0.793), DD(F = 9.895, p = 0.007), SR(F = 1.877, p = 0.391), EUE(F = 1.428, p = 0.490), FF(F = 5.422, p = 0.066). A relation was found between the score of the scales of CEBQ and percentiles: FR(F = 7,435, p = 0.024), EOE(F = 4,757, p = 0.093), RS(F = 1,473, p = 0.479), SE(F = 4620, p = 0.099), DD(F = 1255, p = 0.534), SR(F = 0337, p = 0.845) EUE(F = 2566, p = 0.277), FF(F = 3038, p = 0.219). Conclusion We detected significant differences between breastfeeding practices and regulation of appetite, particularly in the desire to drink, suggesting that exclusively breastfed infants have a lower desire to drink when compared with the others. There is also the existence of a relation between relative-age percentile BMI and appetite regulation, namely the pleasure of eating. Thus, children who are overweight or obese have a greater pleasure in eating.
- Electrospun polycaprolactone membranes functionalized with nanochitin for enhanced bioactivity in localized cancer photodynamic therapyPublication . Costa, Sofia M.; Mattos, Bruno D.; Calhelha, Ricardo C.; Zhu, Ya; Lima, Eurico; Reis, Lucinda; Rojas, Orlando J.; Fangueiro, Raul; Ferreira, Diana P.The encapsulation of photosensitizers (PSs) in electrospun membranes has emerged as a promising approach in photodynamic therapy (PDT) on tumor sites, overcoming the drawbacks associated with systemic administration. In this work, localized implants for cancer treatment using PDT were developed by incorporating EL-2 squaraine into poly(epsilon-caprolactone) (PCL) electrospun microfibers. The latter were coated with chitin nanocrystals (ChNC) by electrospraying, which may improve the biocompatibility and bioactivity of the developed membranes, potentially enhancing the clinical outcomes. The developed electrospun membranes were characterized by water contact angle, imaging, and spectroscopy techniques. The uniform encapsulation and distribution of EL-2 within the microfibers were confirmed while ChNC endowed the membranes with surface hydrophilicity. EL-2 alone displayed about 20 times more cytotoxicity after irradiation compared to the dark condition against HeLa cervical carcinoma cells. Meanwhile, the photodynamic action of PCL+EL-2/ChNC membranes promoted a significant inhibition of cancer cells' proliferation under irradiation, achieving 66.25 % of inhibition, compared to only 24.78 % in dark conditions, using the highest concentration of EL-2. Overall, this work introduces a disruptive strategy using electrospinning-electrospraying to design fibrous therapeutic platforms for cancer PDT, taking advantage of electrospun fibers unique features and the localized nature of photodynamic therapy.
- Práticas de aleitamento e regulação do apetite em crianças em idade pré‐escolarPublication . Soares, Daniela; Moura, Daniela; Reis, Lucinda; Soares, Sara; Almeida-de-Souza, JulianaA amamentação molda a ingestão alimentar em crianças, através da experiência prévia de sabores básicos derivados da dieta materna e ainda pela experiência durante o pri- meiro ano de vida. (Vereijken et al.,2011) No momento das escolhas alimentares, as crianças têm apenas em conside- ração as preferências, com base nos sabores básicos já conhecidos, estando essas mesmas preferências envolvidas na regulação do apetite. (Faith et al.,2004)
- Práticas de aleitamento e regulação do apetite: resultados preliminaresPublication . Moura, Daniela; Reis, Lucinda; Soares, Daniela; Soares, Sara; Almeida-de-Souza, JulianaSegundo a OMS, os bebés devem ser amamentados exclusivamente com leite materno até aos primeiros seis meses de vida, devendo a amamentação ser mantida ao longo da infância o máximo de tempo possível. (1) A ingestão alimentar em crianças é moldada através da experiência prévia de sabores derivados da dieta materna via intrauterina, através da amamentação, e ainda pela experiência ao longo do primeiro ano de vida através da introdução de novos de alimentos incluindo a variedade, o tipo e a frequência de alimentos oferecidos. A forma como cada pai interage com a sua criança incluindo a maneira como introduzem os alimentos, o contexto emocional que cultivam aquando essa introdução e as práticas alimentares que usam, podem influenciar os hábitos alimentares das crianças, quer positiva quer negativamente
- Regulação do apetite e crescimento saudável em crianças em idade pré‐escolarPublication . Moura, Daniela; Soares, Daniela; Reis, Lucinda; Soares, Sara; Almeida-de-Souza, Juliana; Fernandes, AntónioDesenvolver a competência necessária para fazer escolhas seguras e nutritivas é sem dúvida uma conquista fundamen- tal do desenvolvimento, para conseguir uma dieta nutricio- nalmente equilibrada e variada que sustente o crescimento saudável. (Vereijken et al., 2011) Vários estudos mostram que hábitos alimentares saudáveis contribuem para a regu- lação do apetite e têm um impacto positivo sobre o cresci- mento infantil adequado.
