Benefits of Magnesium Supplementation to Broiler Subjected to Dietary and Heat Stress: Improved Redox Status, Breast Quality and Decreased Myopathy Incidence

Poultry is highly sensitive to oxidative reactions. Oxidative reactions have attracted considerable attention from animal and food scientists because of the adverse effects of these reactions on animal welfare, performance and food quality. Despite its implication in multiple biological functions magnesium (Mg) supplementation is typically overlooked in broiler diets. The objective of this study was to evaluate the effect of Mg supplementation (0.3%) using a commercial product (Optibreast\uae) on production parameters, the redox status and meat quality in broilers challenged with dietary (oxidized oil) and heat stress. The incidence of myopathies, namely, wooden breast (WB) and white striping (WS) was also assessed. Mg supplementation had a clear interaction with the absorption/accumulation of Ca in blood and breast muscle but this effect had no negative influence on any of the production parameters under study. Mg supplementation had positive effects on particular meat quality traits such as water holding capacity (WHC) and color. WHC may have other positive effects in turn on relevant sensory traits such as juiciness. Mg supplementation protected against protein oxidation in liver and plasma of broilers. This effect may be related to the increased activity of catalase in such tissues. Mg supplementation reduced the incidence of WS and WB myopathies to almost half the occurrence of such defects in animals fed a control diet. Further studies with a larger number of animals and the application of advanced proteomic/metabolomic tools are required to (1) corroborate the positive influence of Mg on myopathy incidence and (2) identify the underlying molecular basis of the proposed mechanisms

Risk and protective factors for release in outpatients with schizophrenia

eposterWe aim to determine risk and protective factors influencing relapse incidence in outpatient with schizophrenia. A longitudinal, observational study was done with outpatients with schizophrenia (F20) or schizoaffective disorder (F25)(DMS-IV and ICD-10), without hospitalization during the previous 6 months. The patients were consecutively included into the study to received oral (O-A) or long-acting injectable (depot-A) antipsychotics. Clinical stage evolution, compliance, efficacy and safety assessments (including PANSS, CGI-SSI, hospitalization rates, and adverse events) were recorded before and after 6 and 12 months of treatment. Results: 60 outpatients (aged 34.5±8.9, male 73%), 75% schizophrenia and 25% schizoaffective disorder diagnosis, 68.3% fewer than 15 years of schizophrenia evolution, 76.7% fewer than 5 times previous hospitalizations were treated with O-A (41.7%) or depot-A (58.3%) antipsychotics for at least one year. Depot-A treated patients showed a significant higher compliance compared to O-A patients during the all following time, lower PANSS (total, positive and negative) scores and CGI-SSI score (p<0.01), and a delayed relapse incidence and re-hospitalization to more than 1 year in the 48% of patients (relapse % depot/% oral) after 6 months 22.9%/52.0%, and after 12 months 48.6%/4.0%. Conclusion: There were protective factors which delayed relapse incidence in schizophrenia: Use of sustained-release preparations, family support. There were risk factors for occurrence of relapse in schizophrenia: cocaine, heroin and alcohol consumption, absence of family support, greater severity of patients assessed through CGI-SI, male sex, age older than 25 years and long-term evolution of the disorder.Universidad de Málaga.

Flipped classroom based on objective structured clinical examinations analysis by undergraduate students of Pharmacology course from the Podiatry Degree improve their learning and assessment communication skills about medicines

Comunicación cartel con defensa oralWe aim to evaluate the impact of the individual and in-group analysis of OSCEs (filmed by other students) looking for correct and incorrect behaviours and contents in their learning of pharmacology. Summary of work and outcomes: A 5-year prospective study in which students of Pharmacology course from the Podiatry Degree analysed filmed OSCEs individually and in a group in a flipped classroom. Each group (max 5 students) analysed along 1 week a filmed OSCE, prepare a summary of correct and incorrect items related to clinical events, medicines uses, and people behaviours. The students presented their analysis results to the rest of the class. After each presentation, the other students of the class were encouraged to ask questions and after that, the students voluntarily answered a satisfaction survey. Result and Discussion: 405 students, 65.2% female, 20±5.3 years old were included. Students spend 13.4±5.4 h on making the filmed-OSCE analysis. The percentage of students satisfied with this way of studying pharmacology was 96.5%. OSCEs analysis by students increased their percentage of success in the final assessment in both OSCEs-related and OSCEs-non-related questions (+18.5% and +10.1%). Conclusion: Filmed Objective Structured Clinical Examinations analysis by undergraduate students on the Pharmacology course of Podiatry Degree improved their knowledge about medicines use and their communication skills during the assessment.Universidad de Málaga.

Prat Gaballí & Juan Beneyto: an aproximation to introdution to the discipline of public relations in Spain

Este estudio trata sobre los inicios académicos de las relaciones públicas en España, que se producen de la mano de un reducido grupo de profesionales, pertenecientes a otras áreas de la comunicación. A través de las obras de Prat Gaballí (Publicidad Combativa) y Juan Beneyto (Mass Communications y, Teoría y Técnica de la Opinión Pública), se reflexiona y estudian las primeras manifestaciones teóricas en torno a las relaciones públicas, en la creación de un incipiente cuerpo teórico, y su conformación como disciplina académica, a partir de los años cincuenta del presente siglo en nuestro país
