A vitamina D é responsável pela regulação de várias funções, como a homeostase do cálcio. Vários estudos têm pretendido compreender as necessidades de vitamina D de cada espécie, e a sua aquisição na natureza. O presente estudo teve como objetivo abordar a influência da suplementação com vitamina D e cálcio, ou exposição à radiação ultravioleta (UV) sobre os níveis de cálcio ionizado em Eublepharis macularius (...
Atherosclerotic cardiovascular disease (ASCVD) remains the major cause of premature death and disability; effective cardiovascular (CV) risk prevention is fundamental. The World Heart Federation (WHF) Cholesterol Roadmap provides a framework for national policy development and aims to achieve ASCVD prevention. At the invitation of the WHF, a group of experts from the Portuguese Society of Cardiology (SPC), addr...
The gecko leopard (Eublepharis macularius) was first described in 1854 by British herpetol- ogist Edward Blyth. It is one of the most pop- ular pet lizard species, due to its docile tem- perament, ease of maintenance and reproduc- tion in captivity, its high longevity and small size, and its beauty and diversity of colours and patterns. Ultraviolet (UV) radiation is an important behavioural regulator. Vitamin D...
Introduction and objectives: Cardiology has not been seen as an attractive specialty, and women have avoided it for many years. Some surveys have been performed in other countries, but in Portugal, the situation is largely unknown. Methods: An online survey on perceptions of cardiology and professional preferences was sent to 1371 members of the Portuguese Society of Cardiology, of whom 18.2% completed the surv...
Air pollution is one of the main environmental risk factors for health and is linked to cardiovascular diseases, which are the leading cause of mortality worldwide. In this position paper, we discuss the main air pollutants and how they can promote the development of cardiovascular disease or cardiovascular events. We also summarise the main evidence supporting the association between air pollution and cardiova...
Objectives: To compare duration and changes over time in length of hospital stay for very preterm and extremely preterm infants in 10 European regions. Design: Two area-based cohort studies from the same regions in 2003 and 2011/2012. Setting: Ten regions from nine European countries. Patients: Infants born between 22 + 0 and 31 + 6 weeks of gestational age and surviving to discharge (Models of Organising Acces...
INTRODUCTION AND OBJECTIVES: To analyze the experience gained in 10 years of the heart transplantation program of the University Hospital of Coimbra. METHODS: Between November 2003 and December 2013, 258 patients with a mean age of 53.0±12.7 years (3-72 years) and predominantly male (78%) were transplanted. Over a third of patients had ischemic (37.2%) and 36.4% idiopathic cardiomyopathy. The mean age of donors...
INTRODUCTION: Previous studies have associated heart failure (HF) of ischemic etiology with worse prognosis compared to HF from non-ischemic cardiomyopathy. HF treatment has evolved significantly in recent years. Has this evolution had an impact on this prognostic gap? OBJECTIVE: The aim of our study was to compare patients with advanced HF--nonischemic versus ischemic etiology--in terms of baseline characteris...
INTRODUCTION AND OBJECTIVES: Advanced heart failure (HF) remains a major cause of mortality. Identification of new prognostic risk factors is therefore a priority. Anemia, a frequent comorbidity in HF patients and a recognized trigger of symptoms, has recently received considerable attention in this context. Several studies have demonstrated an association between anemia and increased mortality in stable chroni...
OBJECTIVE: To analyze the initial five years experience of the new heart transplant program of Coimbra University Hospitals. METHODS: Between November 2003 aid December 2008, 132 patients were transplanted, with a mean age of 52.0 years (range 3-71 years), of whom 98 were male (74%). Half of the patients had dilated cardiomyopathy and 33% ischemic cardiomyopathy. The mean age of donors was 31.7 years and 102 we...
