There are about 3106 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.
Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.
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).
This study aims to evaluate the clinical, imaging results of endovascular revascularization of the aorto-iliac sector in comparison with aortobifemoral bypass and the hybrid approach, in patients with atherosclerotic disease of the iliac sector classified as type C and D by the TransAtlantic Inter-Society Consensus (TASC II
The goal of this study is to assess the safety and effectiveness of Dostarlimab compared to Placebo in adult participants with HNSCC (Head and Neck Squamous Cell Carcinoma)
This randomized controlled trial aimed to assess the efficacy of a new intervention program for perpetrators of child sexual abuse: the INSIGHT Program. The primary outcome measures to assessing INSIGHT effectiveness will include psychological symptoms, EMSs, cognitive distortions, interpersonal problems, self-esteem, victim empathy, and empathy, and sexual violence risk. Then, qualitative interviews will enable an in-depth examination of the therapeutic process and its effects.
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.
To overcome the lack of knowledge regarding the impact of different "living low, training high" methods on swimming performance, a 4-week intervention will be carried out to determine and compare the effects of three Repeated Sprints in Hypoxia (RSH) methods with each other and with a control group. Our goal is to characterize and compare the adaptations in swimming performance and in cardiorespiratory, metabolic, and muscle oxygenation responses that can arise after a 4-week training period of RSH and RSH-voluntary hypoventilation (VHL) performed in a ski-ergometer.
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.
Exploratory, single-dose, open-label, pharmacokinetic study to establish uptake, plasma levels safety and tolerability of orally administered AUX-001 on an empty stomach (i.e, fasting) as well as after a meal (i.e. fed) in healthy volunteers.
