Podeu consultar el document complet a: http://diposit.ub.edu/dspace/handle/2445/65797En el marc d’un projecte d’innovació docent s’ha implementat l’avaluació per portafolis digital
en assignatures metodològiques del grau de Pedagogia de la Universitat de Barcelona. Amb
l’objectiu de conèixer com el sistema de portafolis afecta a l’organització de la docència, i què
suposa per al professorat aquesta estratègia d’avaluació, s’ha implementat el portafolis digital
en cinc grups del grau de Pedagogia, corresponents a les assignatures: instruments de recollida
d’Informació, teoria i pràctica de la recerca educativa i informàtica aplicada a la recerca
educativa. Han participat vuit docents. S’ha utilitzat l’autoinforme de valoració de l’experiència
per part del professorat implicat. En les valoracions s’han considerat qüestions relacionades
amb l’impacte que té el portafolis en la docència. Els resultats mostren que pel professorat el
portafolis impacta directament en la seva pràctica avaluativa i en la planificació de
l’assignatura. Els docents hi veuen potencial pedagògic, però cal formació i motivació per a
l’alumnat en l’ús i implementació del portafolis durant períodes de temps llargs

Egg Production in Poultry Farming Is Improved by Probiotic Bacteria
Antimicrobial resistance (AMR) is one of the most serious threats for human health in
the near future. Livestock has played an important role in the appearance of antibioticresistant
bacteria, intestinal dysbiosis in farming animals, or the spread of AMR among
pathogenic bacteria of human concern. The development of alternatives like probiotics is
focused on maintaining or improving production levels while diminishing these negative
effects of antibiotics. To this end, we supplied the potential probiotic Enterococcus
faecalis UGRA10 in the diet of laying hens at a final concentration of 108 Colony Forming
Units per gram (CFU/g) of fodder. Its effects have been analyzed by: (i) investigating the
response of the ileum and caecum microbiome; and (ii) analyzing the outcome on eggs
production. During the second half of the experimental period (40 to 76 days), hens
fed E. faecalis UGRA10 maintained egg production, while control animals dropped egg
production. Supplementation diet with E. faecalis UGRA10 significantly increased ileum
and caecum bacterial diversity (higher bacterial operational taxonomic unit richness and
Faith’s diversity index) of laying hens, with animals fed the same diet showing a higher
similarity in microbial composition. These results point out to the beneficial effects of
E. faecalis UGRA10 in egg production. Future experiments are necessary to unveil the
underlying mechanisms that mediate the positive response of animals to this treatment.This research was funded by the Spanish Ministry of Science

Antioxidants and Oxidative Stress in Children: Influence of Puberty and Metabolically Unhealthy Status
Oxidative stress could help explain the relationship between childhood obesity and a
metabolically unhealthy (MU) status. Moreover, puberty could also influence this relationship,
since it entails physiological cardiometabolic changes. We aimed to evaluate plasma antioxidants
and oxidative stress biomarkers in MU and metabolically healthy (MH) prepubertal and pubertal
children and their associations with pro-inflammatory and endothelial damage biomarkers, taking
puberty into account. A total of 1444 Spanish children aged 3–17 years (48.9% males, 66% prepubertal,
47.1% with obesity) were recruited. Blood pressure, anthropometric and biochemical parameters
were measured, and children were categorized as having a MU or MH status according to risk factors.
Retinol, carotenes, tocopherols, total antioxidant capacity (TAC), oxidized low-density lipoprotein
and selected pro-inflammatory and endothelial damage biomarkers were analyzed. General linear
models adjusted for age, sex, recruitment center and body mass index, partial correlations and
stepwise linear regressions were performed. Lower carotenes and tocopherols levels were found in
MU than in MH children. Plasma TAC was lower in prepubertal and higher in pubertal children with
obesity compared to normal-weight children. Antioxidants and oxidative stress biomarkers showed
novel associations with several pro-inflammatory and endothelial damage biomarkers, with pubertal
differences, supporting the importance of considering both the antioxidant and oxidative stress status
and puberty in the prevention of metabolic diseases in childhood.Plan Nacional de Investigacion Cientifica, Desarrollo e Innovacion Tecnologica (I + D + I), Instituto de Salud Carlos III-Health Research Funding (FONDOS FEDER)

Beneficial Shifts in the Gut Bacterial Community of Gilthead Seabream (Sparus aurata) Juveniles Supplemented with Allium-Derived Compound Propyl Propane Thiosulfonate (PTSO)
This study analyzes the potential use of an Allium-derived compound, propyl propane
thiosulfonate (PTSO), as a functional feed additive in aquaculture. Gilthead seabream (Sparus aurata)
juveniles had their diet supplemented with this Allium-derived compound (150 mg/kg of PTSO)
and were compared with control fish. The effects of this organosulfur compound were tested by
measuring the body weight and analyzing the gut microbiota after 12 weeks. The relative abundance
of potentially pathogenic Vibrio and Pseudomonas in the foregut and hindgut of supplemented fish
significantly decreased, while potentially beneficial Lactobacillus increased compared to in the control
fish. Shannon’s alpha diversity index significantly increased in both gut regions of fish fed with a
PTSO-supplemented diet. Regarding beta diversity, significant differences between treatments only
appeared in the hindgut when minority ASVs were taken into account. No differences occurred
in body weight during the experiment. These results indicate that supplementing the diet with
Allium-derived PTSO produced beneficial changes in the intestinal microbiota while maintaining the
productive parameters of gilthead seabream juveniles.AQUAHEALTH project (Operational Programme Smart Growth 2014-2020) IDI-20170032FEDER-INNTERCONECTA-CDTI 2018, Centro para el Desarrollo Industrial, Spanish Ministry of Economy and Competitiveness ITC-20181099Programa Operativo de Empleo Juvenil (Fondo Social Europeo, Junta de Andalucia) 612
Cluster Analysis of Physical Activity Patterns, and Relationship with Sedentary Behavior and Healthy Lifestyles in Prepubertal Children: Genobox Cohort
Sedentary habits during childhood are associated with adverse health outcomes. The aim of this work was to cluster lifestyle behaviors and metabolic biomarkers to establish different patterns in children. Their physical and sedentary activities were evaluated by accelerometry, and questionnaires that included lifestyle behaviors, such as adherence to a Mediterranean diet, anthropometry and blood biochemical markers. Cluster analysis was performed to establish different groups based on physical activity levels. A total of 489 children were finally selected. Cluster 1 included children with a mostly sedentary state, whereas Cluster 3 included the most active children and Cluster 2 included children that did not fit into either the sedentary or the highly active groups. In Cluster 3, 56% of children were in a sports club, and a lower percentage used electronic devices in their rooms compared to the other groups. Cluster 1 children exhibited higher insulin, HOMA-IR and triacylglycerides with respect to the other groups. No differences were found regarding adherence to a Mediterranean diet. The choice to practice an extracurricular sport could be an influencing factor to increase exercise and ensure an active lifestyle in children. Reducing or limiting screen time mainly in children''s rooms could contribute to an active lifestyle
Allium-Based Phytobiotic Enhances Egg Production in Laying Hens through Microbial Composition Changes in Ileum and Cecum
The misuse of antibiotics has led several countries to ban their use as prophylactics against bacterial diseases or as growth promoters in livestock and poultry. Phytobiotics (bioactive
compounds extracted from plants) are one of the alternatives, due to their antimicrobial activity and
its modulation of the gut microbiota and the improvement of productive properties. Garlic and onion
extracts, rich in antimicrobial compounds, are of the most promising alternative to antibiotics. We supplemented a garlic- and onion-based product in the diet to laying hens at the beginning of their productive
life. The group supplied with this product produced in one month more eggs and with bigger size.
This increase in production was accompanied by changes in the bacterial community of the gut. These
changes in the microbiota suggest an improvement in food digestibility, as the most important changes
produced by these compounds occur in the most distal parts of the gut. The relative abundance of
beneficial Lactococcus in the ileum and Lactobacillus in the cecum increased in the experimental group.
Both genera are known to have beneficial effects on host. These results are very promising for the use of
these compounds in poultry for short periods.Phytobiotics (bioactive compounds extracted from plants) are one of the explored alternatives
to antibiotics in poultry and livestock due to their antimicrobial activity and its positive effects on
gut microbiota and productive properties. In this study, we supplemented a product based on garlic
and onion compounds in the diet to laying hens at the beginning of their productive life (from 16 to
20 weeks post-hatching). The experimental group showed a significant increase in the number of eggs
laid and in their size, produced in one month compared to the control. This increase in production was
accompanied by microbiota changes in the ileum and cecum by means of high throughput sequencing
analyses. These bacterial shifts in the ileum were mainly the result of compositional changes in the rare
biosphere (unweighted UniFrac), while in the cecum, treatment affected both majority and minority
bacterial groups (weighted and unweighted UniFrac). These changes in the microbiota suggest an
improvement in food digestibility. The relative abundance of Lactococcus in the ileum and Lactobacillus in
the cecum increased significantly in the experimental group. The relative abundance of these bacterial
genera are known to have positive effects on thSpanish Ministry of Science and Innovation, Consejería

Longitudinal associations between cardiovascular biomarkers and metabolic syndrome during puberty: the PUBMEP study
Puberty has been described as a life stage of considerable metabolic risk specially for those with obesity. The low-grade systemic inflammatory status associated with obesity could be one of the connections with metabolic syndrome (MetS). Thus, we aimed to assess the relationship between inflammatory and cardiovascular biomarkers and the development of MetS during puberty. Seventy-five children from the PUBMEP study (33 females), aged 4–18 years, were included. Cardiovascular and inflammatory biomarkers were measured in the prepubertal and pubertal stage, including high-sensitivity C-reactive protein (CRP), leptin, tumor necrosis factor-alpha (TNFα), interleukin 8 (IL8), monocyte chemoattractant protein 1 (MCP-1), total plasminogen activator inhibitor-1 (tPAI), resistin, adiponectin, myeloperoxidase (MPO), and soluble intercellular adhesion molecule-1 (sICAM-1). MetS was diagnosed at each measurement point. Mixed-effects and logistic regressions were performed. Those children with MetS in puberty presented higher prepubertal values of several cardiometabolic biomarkers in comparison to those without MetS (z-score body mass index (zBMI), waist circumference, insulin, HOMA-IR, leptin, and tPAI (p < 0.05)). For prepubertal children with obesity, the odds of developing MetS in puberty were significantly higher in those having high zBMI (OR = 4.27; CI: 1.39–22.59) or high concentrations of tPAI (OR = 1.19; CI: 1.06–1.43
