Introdução: A obesidade é um problema generalizado e crescente, assim como um dos componentes da Síndrome Metabólica (SM). Em populações saudáveis, a proteína C reactiva (PCR)correlaciona-se com medições de obesidade.
Objectivos: Analisar numa populações de doentes com doença cardíaca, se se mantém a
correlação entre a PCR e as variáveis de SM, assim como a relação entre a PCR e a doença
arterial coronária (DAC).
Material e Métodos: Estudo de 1231 doente admitidos para procedimento cardíaco invasivo
electivo. Obtiveram-se dados antropométricos, valores de PCR, assim como identificação das variáveis componentes de SM. Comparámos os grupos distribuídos de acordo com o Índice de Massa Corporal (IMC) e correlacionámos com PCR e outras variáveis.
Resultados: A frequência global de SM foi de 59%. A PCR foi significativamente mais eleva...
Asset management is assuming higher relevance in utilities’ short and long term management. Governance and policies are playing an important role in the process and, in some countries, regulators and governments are assuring that asset management methodologies are properly followed.
Utilities and their stakeholders should deal with different ‘renewal policies’ approaches, towards better planning processes and a more sustainable way of managing capital expenditure in the long term.
AGS is a Portuguese private operator with contractual responsibilities in 17 concessions and PPPs. Asset management is an important matter for the entire organisation, as a management process and, since 2009, as a legal obligation.
The present paper will describe infrastructure asset management policies in the organisation and the initiative’s roadmap in or...

A key worldwide challenge in most sectors is to boost the effective adoption of innovation, as underpinned by the new European Union research programme Horizon 2020, which focuses on increasing innovation in Europe from 2014 to 2020. This is particularly relevant in the water sector, often perceived as conservative and averse to change. This paper discusses the role that collaborative knowledge-transfer projects can play in effectively rolling out R&D in the water industry. LNEC (Laboratório Nacional de Engenharia Civil) has designed a structured model based on a phased programme and a network of utilities and researchers. The paper presents the core principles, the rationale, the model and methods used, and the theoretical background, as well as the project’s impact, outcomes and products. The discussion highlights the lessons learnt ...
Introdução: Existe alguma controvérsia respeitante ao tipo de revascularização a efectuar no contexto de angioplastia (PCI) primária no enfarte agudo do miocárdio (EAM). A presença de lesões coronárias adicionais, particularmente complexas, poderá ter impacto no prognóstico.
Objectivos: Avaliar o prognóstico a médio-prazo (1 ano) face à presença de lesões adicionais complexas após PCI primária.
População e Métodos: Estudaram-se retrospectivamente 138 doentes consecutivos admitidos na nossa Unidade por EAM com elevação do segmento ST e submetidos a PCI primária. Os doentes foram seguidos por um período de 1 ano e divididos em 2 grupos: sem lesões adicionais complexas (n=69, 61 ± 14 anos, 62% sexo masculino) e com lesões adicionais complexas (n=69, 65 ± 13 anos, 73% sexo masculino, p=NS). Avaliaram-se as características demográfic...
Introdução: O tratamento das Síndromes
Coronárias Agudas (SCA) sofreu várias
alterações muito rápidas nos últimos anos,
traduzido nas múltiplas propostas de
recomendações pelo ACC/AHA/ESC, baseados
na evidência clínica. Avaliamos a
implementação destas recomendações,
comparando uma população de doentes de 2002, com uma população de 2005.
Métodos: Estudo retrospectivo de 368 doentes
admitidos em 2002 e 420 doentes admitidos em 2005 por SCA (com e sem elevação do segmento ST). Analisaram-se características clínicas e estratégias de tratamento.
Resultados: Não se verificaram diferenças em
termos de idade, sexo masculino, factores de
risco para doença coronária ou história prévia de revascularização miocárdica. Verificou-se uma redução de doentes com antecedentes de enfarte do miocárdico e insuficiência renal e aumento da apres...
INTRODUCTION: The definition of subclinical hypothyroidism (SH) is an asymptomatic state in which free thyroxine (T4) is normal and thyroid-stimulating hormone (TSH) levels are elevated. Its relationship with coronary disease is not clear and has been the subject of recent interest. Current evidence is conflicting and there is a lack of studies supported by coronary angiography.
OBJECTIVE: To assess the relationship between SH and the presence and extent of coronary disease diagnosed by angiography.
METHODS: We prospectively studied 354 consecutive patients referred for elective coronary angiography. Those with known thyroid disease, documented coronary disease or previous myocardial infarction were excluded. Fasting blood specimens were collected to measure thyroid hormones, lipid profile, high-sensitivity C-reactive protein, fi...
Cardiovascular disease is among the main causes of mortality and morbidity worldwide. Despite significant advances in medical and interventional therapy, the prognosis of
conditions such as ischemic heart disease is still dismal. There is thus a need to investigate
new therapeutic tools, one of which is stem cell therapy. Hematopoietic stem cells are the
most studied type, and the fact that their biology is relatively well understood has led to their
being used in preclinical research and clinical trials. However, the results of some of these
studies have been controversial, which has opened the way for studies on other cell types, such
as mesenchymal stem cells. These cells have immunomodulatory properties which suggest that
they have therapeutic potential in cardiology. In the present article, the authors review the
state of t...
Water utilities sustainable management is a leading challenge in which data and information analysis play a key role. Nowadays data generated in information systems is too much, evolves too fast and is too diverse, requiring innovative information processing forms to enhance organization’s management. Driven by reporting requirements, legal obligations in developing Infrastructure Asset Management (IAM) plans and the implementation of an asset management policy inside the Group, AGS (Administração e Gestão de Sistemas de Salubridade, S.A.) designed, developed and implemented a dynamic tool to support data management and information analysis. Based on tool’s capabilities, a case study is presented, analysing rehabilitation investment impact on water systems performance. Results have shown that the relations between rehabilitation rates ...
Human resources are one of the most important assets of water utilities being responsible for assuring systems’ management and playing an important role in the tacit forms of the organisational knowledge. In organisations with the responsibility to manage vast, diverse and long life cycle infrastructures, with an adequate level of service and acceptable risk, knowledge transfer between peers should be assured to maintain a stable human resources framework. In water utilities, strategic asset management should include the long term planning of human resources alongside with urban water infrastructure assets to ensure service sustainability. Based on these assumptions and driven by the legal obligations in developing infrastructure asset management (IAM) plans, AGS (Administração e Gestão de Sistemas de Salubridade, S.A.) created and imp...
