Analysis of Genes Involved in Oxidative Stress and Iron Metabolism in Heart Fai...

Introduction: Heart failure (HF) is a clinical syndrome characterized by cardinal symptoms that may be accompanied by signs. It results from structural and/or functional abnormalities of the heart leading to elevated intracardiac pressures and/or inadequate cardiac output at rest and/or during exercise. The prevalence of iron deficiency and anemia justifies the current guidelines recommendation of screening. Ge...

Influence of Immobilization Strategies on the Antibacterial Properties of Antim...

It is key to fight bacterial adhesion to prevent biofilm establishment on biomaterials. Surface immobilization of antimicrobial peptides (AMP) is a promising strategy to avoid bacterial colonization. This work aimed to investigate whether the direct surface immobilization of Dhvar5, an AMP with head-to-tail amphipathicity, would improve the antimicrobial activity of chitosan ultrathin coatings. The peptide was ...

Use of Cognitive Enhancers by Portuguese Medical Students: Do Academic Challeng...

Introduction: Nonmedical use of prescription drugs and other substances for cognitive enhancement in the academic environment has been documented in several studies. However, the prevalence among Portuguese university students is unknown. We aimed to assess the prevalence and academic contexts of the use of cognitive enhancers of a sample of Portuguese medical students. Material and methods: An online questionn...

Parámetros hematológicos descuidados en el pronóstico de la insuficiencia cardí...

Aims: In heart failure patients, anemia and iron deficiency are predictors of poor outcome. We studied the association of anemia, iron deficiency and related hematological parameters with short-term rehospitalization, short-term all-cause mortality and end of follow-up all-cause mortality in heart failure patients. Material and Methods: Anemia, iron deficiency, red cell distribution width and erythropoietin wer...

Distribution of alien tetrapods in the Iberian Peninsula

We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and managemen...

Insuficiencia Cardíaca: una Enfermedad Maligna Conclusiones del Estudio REFERENCE

Gal-3 y ST2 como biomarcadores: un paso al frente en el pronóstico de la Insufi...

Aims: The American College of Cardiology (ACA)/ American Heart Association (AHA) granted Galectin-3 (Gal-3) and Suppression of Tumorigenicity 2 (ST2) evaluation a class II recommendation for HF prognosis, as an adjunctive to conventional clinical risk factors and natriuretic peptides dosing in 2013. However, in Europe this endorsement is not valid. The purpose of this study was to study the association of Gal-3...

AMP-chitosan coating with bactericidal activity in the presence of human plasma...

Antibiotic resistance is increasing and new strategies are needed to fight infection. Advanced materials are promising tools that can be combined with innovative alternatives to conventional antibiotics to allow more targeted and efficient treatment. In this work, we explored the activity against Staphylococcus epidermidis (S. epidermidis) of the a-helical antimicrobial peptide (AMP) MSI-78(4-20) (KFLKKAKKFGKAF...

Diagnosis, treatment, and work impact of iron deficiency anemia in a Portuguese...

Introduction: Little is known about iron deficiency anemia (IDA)'s treatment in Portugal. We aim to estimate the proportion of anemia, IDA, and iron deficiency without anemia; characterize the diagnostic procedures and prescription patterns; assess anemia's impact over work absenteeism, in a Local Health Unit. Material and methods: Cross-sectional study that evaluated complete blood counts, iron-containing pres...
