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.
The improvement or preservation of quality of life (QoL) is one of the three pillars of the European Union (EU) Mission on Cancer, which underpins the needs of patients from cancer diagnosis throughout treatment, survivorship, and advanced terminal stages. Clinical studies and real-world data show that the use of Patient Reported Outcome Measures (PROMs) for QoL assessment in routine oncology practice has positive effects on patient wellbeing and healthcare resource utilization. However, full implementation of PROMs is not yet part of standard of care and is not adequately considered in cancer policies and programs. A comprehensive tool incorporating the perspective of patients at different stages of the disease trajectory and widely applicable across Europe is still lacking. The European Oncology Quality of Life Toolkit (EUonQoL-Kit) is a unified patient-centred tool for the assessment of QoL, developed from preferences and priorities of people with past or current cancer experience. The EUonQoL-Kit includes three electronic questionnaires, specifically designed for different disease phases (patients in active treatment, survivors, and patients in palliative care), available in both static and dynamic (Computer Adaptive Testing, CAT) versions and in several European languages. This is a multicentre observational study, with the following aims: - The primary aim is to perform the psychometric validation of the EUonQoL-Kit. - Secondary aims are to assess its acceptability, to validate the static and dynamic versions against each other, and to provide estimates of QoL across European countries. The EUonQoL-Kit will be administered to a sample of patients from 45 European cancer centres. The sample will include patients in active treatment (group A), survivors (group B), and patients in Palliative Care (group C). Each centre will recruit 100 patients (40 from group A, 30 from group B, 30 from group C), for an overall sample size of 4,500 patients (at least 4,000 patients are assumed to be enrolled, due to an expected lower recruitment rate of 10-15%). Three sub-samples of patients (each corresponding to 10% of the total sample for each centre) will fill in an additional questionnaire: - FACT-G (Functional Assessment of Cancer Therapy - General) and EQ-5D-5L (5-level European Quality of Life Five Dimension), to test concurrent validity. - Live-CAT version, to validate the static and dynamic versions against each other. - EUonQoL-Kit, at least 1 hour after the first completion, to assess test-retest reliability.
The purpose of this study is to assess the safety and efficacy of two doses of Deucravacitinib in adult participants with Active Sjögren's Syndrome.
Bariatric surgery is the most effective treatment for severe obesity, yet a significant percentage of patients achieve suboptimal results or present long-term weight regain. Given the strong association between poor outcomes and post-surgery psychological factors, it is crucial to implement post-surgical psychological interventions. This randomized controlled trial aims to compare the efficacy of a novel, cost-effective, and timely-personalized treatment delivering strategy (stepped-care) with two different intensities 1) low-intensity intervention delivered by Facebook®, and 2) high-intensity program delivered online. It is also intended to study predictors, outcome moderators/mediators, and the underlying mechanisms of weight regain. Participants' assessment will include measures of pathological eating behavior, psychological impairment, negative urgency, and emotional regulation.
This study aims to assess the acceptability, feasibility, and preliminary efficacy of an e-Health psychological intervention specifically designed to promote sexual health, mental health, and general well-being and quality of life in men with prostate cancer. A pilot study will be conducted involving prostate cancer survivors randomly assigned to one of two conditions: the experimental group (receiving the program) vs the control condition (waiting list). The experimental group is expected to improve on outcomes related to mental and sexual well-being when compared to the control group. Furthermore, the experimental group is expected to show good acceptability of the intervention program. This study aims to inform the design and methodology to be adopted in a future randomized controlled trial aimed to further test the e-Health intervention's efficacy.
Adolescence and youth are periods of significant maturational changes which seems to involve greater susceptibility to disruptive events in the brain such as binge drinking (BD). This prevalent pattern of consumption -characterized by repeated alcohol intoxications- is of special concern, as it has been associated with major neurocognitive impairments in the young brain. Recent studies indicate that alcohol may disrupt the gut microbiota (GM) and that these disruptions may lead to impairments in brain and behavior. Also, interventions with psychobiotics have been shown to result in reductions in alcohol-induced damage and in improvements on cognitive and brain functioning. Thus, the present proposal will explore the effects of BD on GM. Additionally, a GM intervention with psychobiotics both in-vivo and in-vitro, will determine whether improvements in GM composition/function may lead to reductions of alcohol-induced brain damage in BD-population, a barely unexplored research field with major clinical applications.
There is increasing awareness of the importance of providing mental health services and support that promote a recovery-oriented and human rights-based approach. A mental health service system that is guided by a rehabilitation and recovery perspective places emphasis on treating the consequences of the illness rather than just the illness "per se", and on empowering people to regain control of their identity and life, and to have hope for the future. Within this philosophy, mental health policies in several countries advocate for the introduction of peer workers in mental health services, people with lived experience of mental health issues and recovery, who are employed to use their lived experience to support those who access mental health services. However, more effectiveness and implementation research is needed. Evidence also suggests that the period following hospital discharge is of high risk of treatment dropout for people with serious mental illness, thus interrupting their recovery process. Therefore, this vulnerable population may particularly benefit from more targeted interventions during this transitional period. The research project will conduct a randomized controlled trial to evaluate the effectiveness, feasibility and implementation of the Critical Time Intervention-Peer Support model, a recovery-oriented based model for people with serious mental illness discharged from inpatient psychiatric treatment facilities in Portugal. The randomized controlled trial (RCT) will be conducted in three psychiatric services in the Lisbon Metropolitan Area and their catchment areas. People with diagnoses of psychotic disorders discharged from inpatient psychiatric treatment facilities will be recruited and randomly divided into CTI-PS intervention or usual care. Those allocated to the intervention group will additionally receive CTI-PS rather than usual care alone over a 9-month period. Outcomes at baseline, 9- and 18-months will be analyzed by multilevel models, considering the observations clustered within sites. Longitudinal analyses will be used to examine trends over time of the outcomes of interest. The implementation of the CTI-PS model will introduce a novel approach to community mental health care that has not yet been tried in Portugal. This study aims to explore to what extent this intervention can be effective and implemented in countries with the characteristics of Portugal. Additionally, the proposed research aims to contribute to the global knowledge about peer interventions by investigating whether the CTI model maintains its effectiveness using peers.
Surgical removal of third molars is recognized as one of the most frequent procedures performed in oral surgery. Literature is rich in studies attempting to demonstrate the benefit of corticosteroids in third molar surgery, however the variety of methods, doses, routes and timing of administration has hampered the standardization of their use in light of best evidence. Also the use of 3D facial superimposition methodology to measure and analyze facial swelling after third molar surgery is a relatively new and promising technology.
This study aims to determine the effects of an orientation exercise program addressed to old on physical-motor, cognitive, and affective competencies. This quasi-experimental study is a controlled trial involving an orientation exercise program. The program will run for 12 weeks (3 sessions per week). Participants will be clustered into two groups: the experimental group will perform the exercise orientation sessions, and the control group will maintain regular activities routines. Evaluations will be performed before and after the intervention. After the study is finished, the control group will attend a similar exercise program.
The primary objective of the study is to determine the effect of seralutinib on improving exercise capacity in subjects with WHO Group 1 PAH who are FC II or III. The secondary objective for this trial is to determine time to clinical worsening.
The purpose of this study is to learn if V940 which is an individualized neoantigen therapy (INT; formerly, called messenger ribonucleic acid [mRNA]-4157) with pembrolizumab (MK-3475) is safe and prevents cancer from returning in people with high-risk melanoma. Researchers want to know if V940 with pembrolizumab is better than receiving pembrolizumab alone at preventing the cancer from returning.
