- Chitosan coated textiles may improve atopic dermatitis severity by modulating skin staphylococcal profile: a randomized controlled trialPublication . Lopes, Cristina; Soares, José; Tavaria, Freni; Duarte, Ana; Correia, Osvaldo; Sokhatska, Oksana; Severo, Milton; Silva, Diana; Pintado, Manuela; Delgado, Luís; Moreira, AndréBackground: Atopic dermatitis (AD) patients may benefit from using textiles coated with skin microbiome-modulating compounds. Chitosan, a natural biopolymer with immunomodulatory and antimicrobial properties, has been considered potentially useful. Objective: This randomized controlled trial assessed the clinical utility of chitosan-coated garment use in AD. Methods: Of the 102 patients screened, 78 adult and adolescents were randomly allocated to overnight use of chitosan-coated or uncoated cotton long-sleeved pyjama tops and pants for 8 weeks. The primary outcome was change in disease severity assessed by Scoring Atopic dermatitis index (SCORAD). Other outcomes were changes in quality of life, pruritus and sleep loss, days with need for rescue medication, number of flares and controlled weeks, and adverse events. Changes in total staphylococci and Staphylococcus aureus skin counts were also assessed. Comparisons were made using analysis of variance supplemented by repeated measures analysis for the primary outcome. Interaction term between time and intervention was used to compare time trends between groups. Results: Chitosan group improved SCORAD from baseline in 43.8%, (95% CI: 30.9 to 55.9), P = 0.01, placebo group in 16.5%(-21.6 to 54.6); P = 0.02 with no significant differences between groups; Dermatology Quality of life Index Score significantly improved in chitosan group (P = 0.02) and a significant increase of skin Coagulase negative Staphylococci (P = 0.02) was seen. Conclusions: Chitosan coated textiles may impact on disease severity by modulating skin staphylococcal profile. Moreover, a potential effect in quality of life may be considered.

- Eating out of home in Portugal: characterization and effects on dietary intakePublication . Silva, Mariana; Rodrigues, Sara S.P.; Correia, Daniela; Rei, Mariana; Severo, Milton; Costa, Ana Isabel A.; Torres, Duarte; Lopes, CarlaThis 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-hour recalls (other age groups) and four eating location categories were defined according to the proportion of meals consumed at out of home locations: Home (at least 80% of meals at home), Other Homes, School or Work and Restaurants and Other Places. The majority of meals (69.1%) were consumed at home. Meals were also often taken at school by children and adolescents, and in restaurants and similar outlets by adults and elderly. Children and adolescents in the School or Work category ate more fruit, vegetables and pulses and cereals and starchy tubers, whereas adults in this category ate more red and processed meats, sugar sweetened beverages and sweets. Compared to Home category, Restaurants and Other Places was associated with worse diet adequacies among children (β=-1.0; 95%CI=-2.0,-0.04), adolescents: (β=-2.4; 95%CI=-3.2,-1.5) and adults (β=-1.3; 95%CI=-1.6,-1.0) reflecting higher intakes of energy, fat, trans and saturated fatty acids, and sodium. The elderly consumed more free sugars and fat when eating out of home in general. Overall, findings reflect important variation in nutrient profiles by eating location, with meals taken at school or work contributing to higher consumption of nutrient-dense foods and those taken in restaurants and other similar settings implying higher consumption of energy-dense foods.

- Prevalence of nutritional inadequacy in children aged 12–36 months: EPACI Portugal 2012Publication . Nazareth, Margarida; Pinto, Elisabete; Severo, Milton; Graça, Pedro; Lopes, Carla; Rêgo, CarlaAdequate nutritional intake in the first years of life is crucial for future health. The purpose of this study is to assess the adequacy of nutritional intake in Portuguese toddlers. The EPACI Portugal 2012 is a cross-sectional study of a representative sample of toddlers (n = 2230), aged between 12 and 36 months. Data on diets were collected by trained interviewers. The current analysis included 853 children with full data from 3-day food diaries completed by parents/caregivers. Intakes of energy, macro- and micronutrients were estimated through Statistical Program to Assess Dietary Exposure (SPADE). Nutritional adequacy was evaluated using Dietary Reference Values established by the European Food Safety Authority. A large proportion of children exceeded the recommended energy intake. The median daily protein intake was 4.7 g/kg/day, five times more than that recommended. About 9% and 90% of the children consumed a lower proportion of energy than the lower limit of the Reference Intake range for carbohydrates and fat, respectively. Around a third consumed less fibre and magnesium and 100% less vitamin D than the recommended Adequate Intake (AI). Almost a third consumed less vitamin A than the recommended Average Requirement (AR) and 86% of the children showed excessive sodium consumption. Portuguese toddlers consumed a low proportion of energy from fat, had energy and protein intakes above the recommendations and excessive intakes of sodium, and inadequate intakes of vitamin A. Every child consumed less than the recommended AI for vitamin D.
