There are about 3174 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.
28 sixth-year medical students will attend a theoretical learning session on coronary angiography. After they will be randomized in 2 groups: a conventional training (CT) group (n=14) and a simulation training (ST) group (n=14). CT group will visualize a video-recorded simulation procedure with duration of 20 minutes, while ST group will perform CA simulated training with SimulHeart in groups of two also for 20 minutes. Finally, after the training session, students' knowledge will be assessed through a theoretical multiple-choice exam and a practical evaluation in a catheterization laboratory using SimulHeart.
Residential care youth show extensive mental health intervention needs due to history of maltreatment and embedded characteristics of residential placement, leading to harmful and cumulative effects throughout development, linked to internalizing and externalizing difficulties. However, existing interventions show limited suitability and poor randomized effectiveness evaluation. To overcome these shortcomings, a new compassion-based program for adolescents in residential care will be developed. A non-randomized trial will be run, testing the program´s effects over adolescents' psychological functioning and investigating whether changes in compassion are associated with changes over time in mental health difficulties. The moderator effect of age, gender and maltreatment history will be investigated. Findings intend to: improve mental-health of youth in residential care, provide an evidence-based intervention to be delivered in residential care settings, increase empirical support of compassion-based interventions, amplifying its scope of delivery.
The purpose of this research project is to optimize the Mind programme for women with breast cancer, taking into consideration the results from its pilot study, and to testits efficacy and cost-effectiveness through a 3-arm randomized controlled trial
The VASCULAID-RETRO study, within the broader VASCULAID project, aims to create artificial intelligence (AI) algorithms that can predict cardiovascular events and the progression of abdominal aortic aneurysm (AAA) and peripheral arterial disease (PAD). The study plans to gather and analyze data from at least 5000 AAA and 6000 PAD patients, combining existing cohorts and retrospectively collected data. During this project, AI tools will be developed to perform automatic anatomical segmentation and analyses on multimodal imaging. AI prediction algorithms will be developed based on multisource data (imaging, medical history, -omics).
The study is being done to see if ziltivekimab can be used to treat participants living with heart failure and inflammation. Participants will either get ziltivekimab (active medicine) or placebo (inactive substance that looks like the study medicine but does not contain any medicine). The treatment participants get is decided by chance. Participant's chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study is expected to last for up to 1 year and 4 months.
This research project aims to analyze the effects of different resistance training volumes on cognitive function, oxidative stress, immunological response, lipid profile, glycemic status, liver function, muscle function, hemodynamic response, and physical performance in individuals with mild cognitive impairment. First the investigators will analyze the effects of a single resistance training session (acute effects) with one and three sets on hemodynamic and physical performance in individuals with mild cognitive impairment. After, the investigators will analyze the effects of an 8-week resistance training program with one or three sets on cognitive function, oxidative stress, immunological response, lipid profile, glycemic status, liver function, muscle function, hemodynamic response, and physical performance in individuals with mild cognitive impairment. The investigators hypothesize that a single resistance training session of one or three sets will increase the acute hemodynamic and physical performance stress in individuals with mild cognitive impairment, although with a higher magnitude in the session with three sets. Furthermore, we hypothesize that eight weeks of resistance training with one or three sets will induce similar improvements in cognitive function, oxidative stress, immunological response, lipid profile, glycemic status, liver function, muscle function, hemodynamic response, and physical performance in individuals with mild cognitive impairment.
The goal of this observational study is to understand if there is a correlation between the evolution of MELD-Na and symptomatic burden of patients with advanced chronic liver disease. All patients with chronic liver disease will be invited to participate in the study. Patients will be followed prospectively with assessment of their MELD-Na score and symptom burden, according to the Edmonton Symptom Assessment System scale.
Analysis of MRI advanced techniques in degenerative spinal disease. The main questions it aims to answer are: - Can we assess microstructural integrity of compressed nerve roots in degenerative spinal disease - What are the image biomarkers affected by disease - How they evolve with disease progression and treatment
This is a multicenter, randomized, placebo- and active-controlled, parallel-group, 24-week trial to investigate the efficacy, safety, and tolerability of XXB750 in participants with HFrEF/HFmrEF.
This study includes a community-based, two-arm prospective acceptability study, whereby arm 1 consists of an educational session on sexual health and cervical cancer (screening) and a follow-up assessment after 3 months. Arm 2 consists of an educational session on sexual health and cervical cancer (screening) and self-sampling, additionally women will be asked to take a self-sample on-site, followed by a follow-up assessment after 3 months. Attitudes, uptake and users' experiences related to the use of a HPV self-sampling test will be assessed, additionally, the impact on looking for follow up care of self-sampling with standard cervical screening strategies will be assessed and finally the feasibility of an HPV self-sampling in hard-to-reach groups versus educational sessions and standard care will be compared (arm 1 and 2).
