There are about 3194 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.
This study will evaluate the effects of elafibranor (the study drug) in participants with Primary Sclerosing Cholangitis (PSC). PSC is a rare disease of the liver that leads to injury and destruction of bile ducts. Damage to bile ducts leads to buildup of bile in the liver, which then causes further damage, and leads to disease progression. This study will compare elafibranor to a placebo, a dummy treatment. The main objective of the trial will be to study the safety and side effects of the study drug. The trial will also study the study drug's effects on blood tests and other tests related to PSC disease activity.
An increasing number of cancer patients are eligible to receive immunotherapy. Efficacy and tolerance have been demonstrated in multicentre randomized clinical trials with positive results. However, real-life experience differs from clinical trial results, especially regarding the management of potential adverse events. HR-QoL (Health Related Quality of Life) is one of the components of QoL (Quality of Life) in its broad acceptation and is certainly the only one usually collected in trials while little is known about QoL in cancer patients treated in the 'real-world'. QUALITOP partners intend to bring together all relevant longitudinal information present in large heterogeneous data (big data) to estimate patient QoL and find surrogate markers of QoL and its evolution. Within the QUALITOP consortium, 5 countries will collect prospective clinical and QoL data and also retrospective clinical data, and share it. This project will enable collecting, managing, sharing, modelling, processing, and exploiting big data on QoL. Furthermore, beyond the description of QoL, analytical tools (including causal inference methods and machine learning) are needed to understand the determinants of QoL and their complex relationships with irAEs (immune related Adverse Events) in a big-data context where standard statistical techniques would be limited. Artificial intelligence and causal models may be applied and developed to empower the patient, prevent adverse medical conditions, and promote QoL. The created knowledge will enable proposing guidelines for promoting better QoL. QUALITOP aims at identifying the determinants of health status regarding immunotherapy-related adverse events (IR-AEs, such as toxicities) depending on the patient's profile in a real-world context. The richness of QUALITOP is in the diversity of the experts who will collaborate in it. Clinicians involved in the care (thus the health status of the patients) will collaborate with psychologists and sociologists to understand and integrate complementary dimensions of QoL related to immunotherapy. Experts in pharmacovigilance and pharmacists will investigate the IR-AEs and their associations with patient behaviour and non-drug consumption. Epidemiologists, data scientists (including bioinformaticians and biostatisticians) and economists will extract information from the data and develop simulation models to produce knowledge. The project will take place in close relation with patient associations that will interact with experts to design the analyses, interpret their results, and proceed to their dissemination. The main objective is to collect data of patients receiving immunotherapy in order to describe its impact in their quality of life. - Create the first real-life cohort of cancer patients treated with immunotherapy within a context of multidimensional management (with data on clinical information, health-related QoL (HR-QoL), IR-AEs, drug consumption, lifestyle, and administrative data). - Accelerate knowledge directed to different stakeholders (patients, relatives, clinicians, pharmacists, health authorities, and the general public) for a better understanding of the determinants of QoL and its optimization after immunotherapy through the development of innovative analytic tools (artificial intelligence and causal models). - Produce policies and recommendations to improve patients QoL and participate in the implementation of the SDGs (Sustainable Development Goals) for 4P medicine (Predictive, Preventive, Personalized, Participative) in immunotherapy for cancer patients.
This randomized controlled trial aims to test the efficacy of an early parenting intervention for childhood behavior problems in the portuguese community. More specifically, this research intends to: 1) examine the effects of the parenting intervention in childhood behavior problems, positive parenting skills and parental concerns; 2) test participants' adherence, acceptability and dropout rates of the parenting intervention; and 3) qualitatively analyze the experience of parents' who received the intervention. Researchers will compare an intervention group with a waitlist control group to see if there are any significant differences between these groups regarding childhood behavior problems and the aforementioned parenting dimensions. Participants in both groups will be able to participate in the parenting intervention that has a duration of 9 weeks. Furthermore, they will be asked to fill in pre and post data.
The National Varicose Vein Study is a cross-sectional, multicenter, observational study. The primary goal is to evaluate the 30 days outcome of the conventional great saphenous vein surgery (stripping) in the treatment of the symptomatic chronic venous insufficiency, comparing the results of difference Portuguese's health centers, comparing the following variables: thrombo-prophylaxis (pharmacology or mechanic; compliance); antimicrobial prophylaxis; quality of life; medication compliance; complications and work incapacity period.
The retinal vessels have been shown to reflect vascular changes inherent to systemic pathologies, even when no ocular disease is identified. As such, the eye's vasculature is ableto serve as a window to the vascular health of the human body and a means of assessing systemic endothelial function. Optical coherence tomography angiography (OCTA) employs optical means to image all the retinal vascular layers and the choroid, providing an extremely detailed image of the microvascular network in a fast, reproducible and totally non-invasive way. As such, it is currently the best non-invasive way of having an image of human capillaries. Recently, OCTA has been used to study the retinal vessels' structure and function in several cardiovascular diseases. As an example of its predictive potential, reduced retinal microvascular density has been associated with the cardiovascular risk profile in patients admitted to the hospital for an acute coronary syndrome. Recent studies have also shown the retinal microvasculature density to be reduced in patients with carotid artery disease (CAD), namely carotid stenosis, and that endarterectomy increases retinal flow and vessel density.
The purpose of this study is to evaluate the effectiveness and safety of deucravacitinib compared with placebo in an active moderate to severe Systemic Lupus Erythematosus (SLE) population.
The primary objective is to evaluate the safety and tolerability of AMX0035 over 108 weeks of open label treatment for participants previously enrolled in Study A35-004 (PHOENIX).
The purpose of this study is to evaluate the effectiveness and safety of deucravacitinib compared with placebo in an active moderate to severe Systemic Lupus Erythematosus (SLE) population.
Investigating different periodontal surgery techniques to treat gummy smile.
Older adults develop modifications in the execution of movement that lead to impairments in activities of daily living performance. Accordingly, there is a need for technological advances in devices that assist older adults targeting improvements in parameters of movement performance that have the highest impact on the skills of daily living. Therefore, to gather the parameters of movement impacting daily living activities, the main goal of this study is to perform a comparative analysis of the biomechanical movement parameters between older adults with and without disability, performing the tasks: gait, sit-to-stand, timed up and go, quiet standing and climb and descend stairs.
