There are about 3168 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 goal of this clinical trial is to test, through a Randomized Controlled Trial (RCT), the efficacy of a selective and short intervention based on second and third-wave cognitive-behavioral interventions (named EMPOWER) for the initial problematic grief reactions and to study potential predictors of adherence and efficacy in bereaved relatives of palliative and oncological patients. The main question is whether EMPOWER intervention is more effective than Treatment as Usual (TAU) in preventing Prolonged Grief Disorder (PGD). Participants with initial indicators of risk of developing PGD will be randomly allocated to EMPOWER and TAU. The primary outcome considered will be symptoms of PGD. The assessment also includes measures of anxiety and depression, attachment, coping, psychological flexibility, posttraumatic growth, and therapeutic alliance. Apart from screening, three assessment moments will be considered: T1: before the first session; T2: at the last session (up to twelve weeks); and T3: follow-up assessment period at 6 months after the previous assessment.
This study will test a medicine, NNC6019-0001, for people who have a heart disease due to TTR amyloidosis. It will look at how safe this medicine is in the long term and if it can reduce symptoms of a heart disease due to TTR amyloidosis, such as heart failure. It is an extension to a study called "A research study to look at how a new medicine called NNC6019-0001 works and how safe it is for people who have a heart disease due to TTR amyloidosis". Only participants who have completed that study will be invited for this new study. Participants will get NNC6019-0001, regardless of whether they got placebo or NNC6019-0001 in the first study. The study will last for up to 157 weeks (36 months/3 years).
Perioperative chemotherapy with fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT4) is the standard perioperative treatment for resectable and advanced gastric adenocarcinoma. Although the FLOT4 regimen have shown increases in the overall survival, response rate, and progression-free survival, it is also associated with substantial toxicities. Prehabilitation is an effective strategy to improve physical fitness in cancer patients and reverse functional limitations and inadequate levels of physical activity that are associated with worse postoperative outcomes and treatment response. Therefore, the main objective of this study is to evaluate the effects of an online, supervised exercise-based prehabilitation program on the cardiorespiratory fitness level, functional fitness and quality of life among adults with gastric cancer undergoing neoadjuvant chemotherapy.
The purpose of this observational study is to understand and evaluate the physiological, psychological, and cognitive impact of 15 consecutive days of air search and rescue mission deployments on Portuguese Air Force crews. The main goals are: 1) Characterize and compare the body composition, cardiorespiratory fitness, and strength levels of air force search and rescue mission crew members with different tasks; 2) Characterize the physiological, psychological and cognitive impacts induced by a single deployment; 3) Identify possible cumulative effects of successive deployments on the variables of interest; 3) Characterize the changes in lifestyle, quality of sleep and nutrition induced by the deployments. The participants will be evaluated after a period of hollidays, before missions, during missions, upon arrival, for a period of twelve months, and at the end of twelve months.
A migraine attack is a moderate or severe headache that usually occurs on one side of the head and is often accompanied by throbbing, sensitivity to light, sensitivity to sound, nausea, or other symptoms. The main goal of the study is to see if atogepant is effective, safe, and well-tolerated in treating migraine attacks quickly. Atogepant is a medicine currently approved for the preventive treatment of migraine in adults and has been shown to be effective and well tolerated when taken daily to prevent migraine attacks. This study includes double-blind phase means that neither the participants nor the study doctors know who is given which study treatment (atogepant or placebo) followed by an open-label phase meaning that both participants and study doctors know which study treatment is given. All participants will receive atogepant during the open-label part of the study. This study will include 1300 participants aged 18-75 years with a history of migraine at approximately 160 sites across the world. All participants will receive both atogepant and placebo to treat qualifying migraines. At the start of the study, participants will be randomized to 1 of 4 dosing sequences to determine when they will receive atogepant and when they will receive placebo during the study. After treating 4 qualifying migraine attacks, participants will receive open-label atogepant for any additional migraine attacks they have until the end of the study (Week 24). There may be a bigger responsibility for participants in this study than there would be in participants receiving standard of care treatment. participants will attend regular visits during the study at a hospital or clinic, as well as telephone visits, and the effects of treatment will be checked by completion of questionnaires in an electronic diary, medical assessments, blood tests, and checking for side effects.
Determine the nursing care needs of the elderly population sample according to the self-care deficits identified using the "Self-Care of Chronic Illness Inventory - Patient Version (version 4)" in elderly population living in their own homes or in the homes of relatives or friends in the district of Évora.
The goal of this registry is to learn more about cytolytic vaginosis, a little known and controversial condition. The main questions the registry aims to answer are: - What are risk factors of cytolytic vaginosis? - Are there defining symptoms of cytolytic vaginosis? - What features on wet mount should be used to diagnosis cytolytic vaginosis? - Are baking soda vaginal irrigations an effective treatment for cytolytic vaginosis? - Do characteristics of cytolytic vaginosis vary between sites/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
