There are about 2409 clinical studies being (or have been) conducted in Portugal. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The present work proposes to find if a bio-active composite in the hemolymph or plasma of the freshwater bivalve Anodonta cygnea is able to offer immunity and specificity for meliorating the major symptoms in human SARS / COVID-19 lineage infection. The Methodology concerns in silico procedures using organic fluids from 54 bivalves (in very specific conditions) to evaluate their therapeutic effects in 6 voluntary SARS / COVID-19 infected persons with an integrative diagnosis by a computational Mora®Nova apparatus to access the basal and experimental human physiological parameters.
Severe Acute Respiratory Syndrome (SARS) Coronavirus (CoV) 2 infection and the associated coronavirus disease 2019 (COVID-19) are the most recent international health threat challenging our ability to protect populations, to avoid severe outcomes and to understand both the population dynamics of this new condition and the breath of individual responses. Gathering information on the clinical course of the disease and the risk of transmission is essential to design effective therapeutic solutions and preventive measures. The aim of the study proposed, to be carried out at University Hospital Center of "São João" (CHUSJ), is to recruit and follow-up a cohort of patients diagnosed with SARS-CoV-2 infection, to evaluate the clinical course of SARS-CoV-2 infection and COVID-19 cases, to identify prognostic factors and to measure the risk of reinfection. Additionally, researchers intend to characterize the patients and household contacts to describe the dynamics of infection, to calculate household infection attack rate, and to perform the genetic sequencing of SARS-CoV-2 to understand determinants of disease course (namely long-term effects) and risk of household transmission. A sample of participants, identified during the process of evaluation of symptomatic individuals, at the same institution, and negative for SARS-CoV-2 will be selected as negative controls. Participants will be consecutively recruited and the study is expected to enroll patients as long as the pandemic remains. Information will be gathered based on clinical individual charts, hospital data-bases (example: for administrative data) and individual computer assisted interviews to be performed at pre-defined intervals (3, 12 and 24 months) or according to clinical needs. The project was approved by the local Ethical Committee and the Data Protection relevant authorities.
The investigators propose an observational study including patients with inflammatory bowel disease under biological therapy with anti-TNF, anti-integrin α₄β₇ or anti-interleukin 12-23 (Ustekinumab), followed by an external Gastroenterology consultation at Centro Hospitalar Tondela-Viseu.
Dementia is a neurodegenerative syndrome that leads to cognitive deficits and, consequently, affects functionality and quality of life. This study will explore the clinical impact of a customized cognitive stimulation program, using Musiquence.

Researchers are looking for a better way to treat people who have chronic kidney disease (CKD), a long-term, progressive decrease in the kidneys' ability to work properly. When CKD happens in people with type 2 diabetes mellitus, a condition characterized by high blood sugar levels, CKD is also referred to as diabetic kidney disease (DKD). FIGARO-BM is an add-on study in which blood draws that were collected in the FIGARO-DKD study are further analyzed. No additional blood draws (also referred to as biological samples) or data will be obtained from the participants, nor will any additional or new study intervention be introduced. No visit or patient contact other than for obtaining the agreement by the patients (also called informed consent) will be required. Inflammation and scarring are both seen as responsible for worsening of chronic kidney disease. There is much information from animal studies that the study treatment finerenone (BAY94-8862) works against inflammation and against scarring (also called fibrosis) in organs such as the kidney. In this exploratory study researchers want to learn more about the study treatment finerenone (BAY94-8862). To find this out, this study will examine substances called biomarkers in blood draws from participants in the FIGARO-DKD study. Biomarkers are used as indicators of biological processes, disease processes or responses to medication. The biomarkers that will be examined stand for inflammation, organ scarring (also called fibrosis), blood vessel function and congestion. The main question of this study is whether there are differences between these biomarkers in the group of participants who received finerenone and the group of participants who received a placebo in the FIGARO-DKD study. A placebo looks like a treatment but does not have any medicine in it. To answer this question, the researchers will compare the levels of these biomarkers between the two groups at different time points after starting the study treatment. Blood samples for this study will be obtained from FIGARO-DKD study sites with a high number of participants who had been treated with finerenone or placebo for at least 24 months. This information will be combined with other information from biomarker examinations already available in the FIGARO-DKD study.
To investigate the PK of cenerimod in participants with severe renal impairment as compared to healthy control participants.
Head and Neck Squamous Cell Carcinoma (HNSCC) is the 6th most common cancer. Most cases are diagnosed in locally advanced stages, with treatment involving multimodal approach with combinations of radiotherapy, surgery and chemotherapy. The aggressive nature of HNSCCs and treatment modalities are associated with important acute and late toxicities that often promote temporary or definitive treatment interruption and may compromised the capability to tolerate subsequent treatments. Thus, the aim of this study is to analyze the acute and long-term impact of cancer treatment on quality of life, physical and cognitive function of HNSCC patients diagnosed with a locally advanced disease.
