Adrenal Vein Sampling in the Management of Primary Aldosteronism: The Added Val...
Manique, I; Amaral, S; Matias, A; Bouça, B; Serranito, S; Torres, J; Gutu, O; Bilhim, T; Coimbra, E; Rodrigues, I; Godinho, C; Cortez, L; Silva-Nunes, JIntroduction: Primary aldosteronism is the most common cause of secondary hypertension. Adrenal vein sampling is the gold standard for subtyping primary aldosteronism. However, this procedure is technically challenging and often has a low success rate. Our center is one of the very few performing this technique in our country with an increasing experience. Objective: The aim of this study was to evaluate the ro...
Transcatheter Aortic Valve Implantation Outcomes in Patients with Low Flow Low ...
Castelo, A; Grazina, A; Mendonça, T; Rodrigues, I; Garcia Brás, P; Ferreira, V; Ramos, R; Fiarresga, A; Cacela, D; Cruz Ferreira, RBackground: Some studies suggest that patients with low flow low gradient (LF-LG) aortic stenosis (AS) may achieve worse results after undergoing transcatheter aortic valve implantation (TAVI). Purpose: To compare outcomes between LF-LG AS and high gradient (HG) AS patients submitted to TAVI. Methods: Inclusion of 480 consecutive patients who underwent TAVI between 2008 and 2020 at a single tertiary center. Pat...
Food Insecurity Levels among University Students: A Cross-Sectional Study
Marques, B; Azevedo, J; Rodrigues, I; Rainho, C; Gonçalves, CBackground: University students may be vulnerable to food insecurity (FI) due to limited financial resources, lower purchasing power, and increasing housing and food costs. This study aimed to assess the prevalence and severity of FI and its associated factors among university students attending a public Portuguese university. Methods: A cross-sectional survey was designed, and data were collected using a self-...
Impact of the COVID-19 pandemic on tuberculosis services
Rodrigues, I; Aguiar, A; Migliori, GB; Duarte, RBackground: In Portugal, Outpatient Tuberculosis Centres (OTBC) are responsible for the diagnosis, treatment, screening and prevention of tuberculosis (TB), and only severe or resistant cases are hospitalized. Aim: To understand how infection control norms and standards were applied and how these centres responded during the pandemic. Method: We sent an electronic questionnaire to all coordinators of OTBC. The ...
Unveiling the Metabolic Effects of Glycomacropeptide
Pena, MJ; Costa, R; Rodrigues, I; Martins, S; Guimarães, JT; Faria, A; Calhau, C; Rocha, JC; Borges, NFor many years, the main nitrogen source for patients with phenylketonuria (PKU) was phenylalanine-free amino acid supplements. Recently, casein glycomacropeptide (GMP) supplements have been prescribed due to its functional and sensorial properties. Nevertheless, many doubts still persist about the metabolic effects of GMP compared to free amino acids (fAA) and intact proteins such as casein (CAS). We endeavour...
Prevalence and Prognostic Impact of Apical Sparing Contractility Pattern in Pat...
Ferreira, V; Aguiar Rosa, S; Pereira-da-Silva, T; Rodrigues, I; Gonçalves, A; Mendonça, T; Castelo, A; Branco, LM; Galrinho, A; Fiarresga, A; Ramos, RIntroduction: Prolonged afterload increase in aortic stenosis (AS) may alter left ventricular (LV) contractility, irrespective of LV ejection fraction (LVEF). The prevalence and morbimortality associated with the apical sparing strain pattern (ASP), a typical finding of cardiac amyloidosis (CA), are not fully understood in patients with AS. We assessed the prevalence of the ASP in patients with severe AS and it...

Biocompatibility of the biopolymer cyanoflan for applications in skin wound hea...
Costa, R; Costa, L; Rodrigues, I; Meireles, C; Soares, R; Tamagnini, P; Mota, RThere is a great demand for the development of novel wound dressings to overcome the time and costs of wound care performed by a vast number of clinicians, especially in the current overburdened healthcare systems. In this study, Cyanoflan, a biopolymer secreted by a marine unicellular cyanobacterium, was evaluated as a potential biomaterial for wound healing. Cyanoflan effects on cell viability, apoptosis, and...
Prognostic Effect and Modulation of Cardiac Sympathetic Function in Heart Failu...
Ilhão Moreira, R; Abreu, A; Portugal, G; Oliveira, L; Oliveira, MM; Rodrigues, I; Coutinho Cruz, M; Silva Cunha, P; Santos, V; Santa Clara, HBackground: Cardiac autonomic dysfunction as assessed by 123I-metaiodobenzylguanidine (123I-mIBG) scintigraphy is associated with poor prognosis in heart failure (HF) patients. Although cardiac resynchronization therapy (CRT) has emerged as an effective therapy in improving outcomes on HF patients, its effect on cardiac sympathetic nervous function is still not fully understood. We aimed to study the value of p...
Relationship of Left Ventricular Global Longitudinal Strain with Cardiac Autono...
Coutinho Cruz, M; Abreu, A; Portugal, G; Santa-Clara, H; Silva Cunha, P; Oliveira, MM; Santos, V; Oliveira, L; Rio, P; Rodrigues, I; Morais, LABACKGROUND: Heart failure (HF) is associated with cardiac autonomic denervation (AD), which can be non-invasively assessed by 123I-metaiodobenzylguanidine (123I-mIBG) scintigraphy and has prognostic implications. We aimed to study the relationship between myocardial contractility assessed by global longitudinal strain (GLS) and AD assessed by 123I-mIBG scintigraphy in advanced HF. METHODS/RESULTS: BETTER-HF is ...
