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.
Baobab fruits have been traditionally used in Africa due to its therapeutic proprieties attributed to it high polyphenol content. The aim of the study was to investigate the effect of baobab fruit on postprandial glycaemia on healthy adults and to measure its bioactive compounds and antioxidant activity. The study was conducted on 31 healthy subjects. The participants were randomly allocated in control group (oral glucose tolerance test (OGTT); n = 16) and in intervention group (OGTT followed by administration of 250 ml baobab aqueous extract (BAE); n = 15). Total phenols, proanthocyanidins, hydrolysable tannins and antioxidant activity (FRAP, DPPH, ABTS and inhibition of O2•- and NO• methods) were quantified. Repeated Measures ANOVA of mixed type and Independent samples t-test were used.
Small bowel capsule endoscopy (SBCE) has become an important tool in clinical practice since its introduction in 2000. This non-invasive method allows the visualization of small bowel mucosa, being essential in the management of many conditions, such as suspected small bowel bleeding, inflammatory bowel diseases and intestinal polyposis syndromes. Despite recommendations concerning SBCE in different pathologies, there are still some technical concerns to be addressed. The optimal preparation for SBCE has been one of these controversial issues. Currently, the European Society of Gastrointestinal Endoscopy (ESGE) recommends that patients ingest a purgative agent (2L of polyethylene glycol, PEG) and antifoaming agents for SBCE, because it was associated with a better visualization. However, it remains unclear which is the optimal timing for purgative use. Furthermore, the use of a booster agent after capsule ingestion is already performed in colon capsule endoscopy, but less is known about its application in SBCE. Also, it remains to be clarified whether a better visualization results in higher diagnostic yield and impacts patients' outcomes. Therefore, the global aim of this prospective, randomized, multi-centric study is to determine the optimal timing and preparation for small-bowel capsule endoscopy (regardless of the equipment used), comparing four groups of different preparation protocols: - Protocol 1) 1L of Moviprep® solution the night before the procedure - Protocol 2) 1L of Moviprep® solution up to 2h before the procedure - Protocol 3) 0.5L of Moviprep® solution up to 2h before the procedure plus 0.5L of Moviprep® solution after the capsule had reached the duodenum (assessed with real-time viewer) - Protocol 4) 1L of Moviprep® solution after the capsule had reached the duodenum (assessed using real-time viewer)
Many cancer survivors are at risk for cardiovascular disease (CVD); it is therefore important to identify patients at increased risk for cardiotoxicity, especially in the setting of CVRF or pre-existing CVD, and to design personalized interventions to prevent cardiovascular morbidity. In this background, cardio-oncology rehabilitation frameworks for specific cancer patients have been proposed. Given potential beneficial effects of exercise among cancer patients (including those at higher risk of CVD), data pertaining to optimal program designs are of paramount contemporary importance. Thus, the aim of this study is to compare the impact of a Cardiac Rehabilitation Program (CRP) model versus a community-based exercise intervention plus usual care on cardiorespiratory fitness (CRF), physical function domains and CVRF control in adult cancer survivors who have been exposed to cardiotoxic cancer treatment and/or with cardiovascular medical background. Study outcomes will be assessed at baseline (M0) and after an 8 weeks-intervention (M1), comprising maximal aerobic capacity (peak oxygen uptake), muscular strength, neuromuscular function, single CVRF control including physical activity measurements and psychosocial parameters, health-related quality of life, fatigue, health literacy, inflammatory response and feasibility metrics; an economic evaluation will provide quantitative comparison, for a cost-effectiveness analysis
This study is being done to see if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in. All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer.
This is a phase III randomized open label study designed to compare JDQ443 as monotherapy to docetaxel in participants with advanced non-small cell lung cancer (NSCLC) harboring a KRAS G12C mutation who have been previously treated with a platinum-based chemotherapy and immune checkpoint inhibitor therapy either in sequence or in combination.
This study compares the effectiveness of a new layered thermal insulation system (SIT-3c) versus the traditional thermal body protection (warmed forced air system) for patients under total knee arthroplasty, during the intra-operative phase.
The purpose of this study is to evaluate the effect of olezarsen (formerly known as AKCEA-APOCIII-LRx) on the percent change in fasting triglycerides (TG) from baseline.
mINSPIRERS_RCT aims to assess the magnitude of the effect of a mobile app for improving asthma control in adolescents and adults with persistent asthma, followed at primary and secondary care in Portugal.
This study will evaluate the effectiveness and safety of a 36-week refill regimen for the Port Delivery System with ranibizumab 100 mg/mL (PDS Q36W) compared with intravitreal injections of aflibercept (2 mg) administered per treat-and-extend (aflibercept T&E) in subjects with neovascular (wet) age-related macular degeneration (nAMD).
This study will evaluate the efficacy, safety, antiviral activity, and pharmacokinetics of study drug RO7496998 (AT-527) compared to placebo in non-hospitalized adult and adolescent participants with mild to moderate coronavirus disease 2019 (COVID-19) in the outpatient setting.
