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.
A laser treatment for periimplantitis using two different wavelengths (Er:YAG and Nd:YAG) will be compared to standard treatment in a randomized clinical trial.
This is an international, multicenter, open-label, non-comparative, Simon´s two-stage design, phase II clinical trial.
This is a randomized, double-blind, active-controlled phase 3 study of ABP 959 in participants with paroxysmal nocturnal hemoglobinuria.
Colonoscopy is currently accepted as the gold standard in screening, surveillance and prevention for colorectal cancer (CRC), and therefore, its quality is a major priority. The quality of colonoscopy is greatly dependent on the quality of the bowel preparation. Standard bowel cleansing includes a low-fibre diet on the day preceding the exam and a split regimen of 4 litres of polyethylene glycol (PEG) solution. In order to improve bowel cleansing some additional measures are available. Simethicone is an inexpensive and safe antifoaming agent that reduces the surface tension of air bubbles, theoretically presenting several benefits such as increased tolerability to the preparation, thereby improving the quality of the preparation and, secondly, adenoma detection (ADR) and cecal intubation rates (CIR). However, its role remains controversial, with some publications supporting its administration and others failing to demonstrate clear benefits. The main aim of this study is to assess if addition of simethicone to a split-dose cleansing regimen of 4 litres of PEG improves adequate bowel preparation rate.
The XIENCE 28 USA Study is prospective, single arm, multi-center, open label, non-randomized trial to evaluate safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS and XIENCE Sierra EECSS) of coronary drug-eluting stents.
The purpose of this study is to demonstrate comparability of the ORR in patients with previously untreated, advanced stage FL who receive GP2013-treatment to patients who receive MabThera-treatment.
Subsyndromal delirium (SSD) is a condition characterized by a less severe cognitive impairment in comparison to delirium. To date there is no published consensus on SSD definitions and has been commonly reported as an intermediate stage between delirium and normal mental states. SSD encompasses some of the delirium symptoms, and has been diagnosed with Intensive Care Delirium Screening Checklist scale (ICDSC) and Confusion Assessment Method-ICU (CAM-ICU). The objective of this study is to identify subsyndromal delirium prevalence, the association between SSD and clinical outcomes and understanding the relationship between SSD and conversion to delirium. The relevance of this study is understanding of subsyndromal delirium in ICU, namely the importance of early presentations of acute brain dysfunction in the patients outcome.
This study will look at the long-term effects of semaglutide (active medicine) on diabetic eye disease when compared to placebo (dummy medicine). The study will be performed in people with type 2 diabetes. Participants will either get semaglutide or placebo in addition to their diabetes medicines - which treatment the participant gets is decided by chance. Participants will inject the study medicine using a pen-injector. The medicine must be injected in a skin fold in the stomach, thigh or upper arm once a week. The study will last for 5 years.
Our main challenge is to develop a novel physical activity intervention to promote exercise participation sustainability and effective health benefits in type 2 diabetes (T2D) population with minimum health risks. The relevance of this study is supported by four cornerstones: 1) The Portuguese love football and there seems to be a major potential in the implementation of football practice as part of the prevention and treatment of noncommunicable diseases for the middle-aged and elderly Portuguese population; 2) no studies have assessed the feasibility and safety of a walking football exercise program for middle-age and older patients with T2D; 3) the proposed investigation relies on robust methodology; 4) this intervention can have further sustainability with the enrollment of football clubs and primary health care units.
Research question: If adults with bone or joint infection have local antibiotic therapy, can they do without prolonged treatment with antibiotics by mouth (oral) or injection? Adults with bone or joint infections are usually given long courses of oral antibiotics or into a vein (intravenous) following surgery. It is also safe to give antibiotics directly into the bone or joint at the time of surgery: this is called local antibiotic therapy. This study investigates whether using local antibiotic therapy would allow shorter courses of oral or intravenous antibiotics, in order to limit antibiotic resistance, side effects and cost. This study compares short against long courses of oral or intravenous antibiotics for adults who have been given appropriate local antibiotic therapy to treat bone or joint infection. Patients who can take part will be randomly divided into two groups within 7 days of surgery. One group will stop oral or intravenous antibiotics, while the other group will continue for 4 weeks or more (standard treatment). Adults with bone and joint infections who have already had surgery and local antibiotic therapy will be invited. Patients will not take part if they need intravenous antibiotics for another reason, or if their infection is caused by bacteria resistant to the antibiotic(s) used in their local antibiotic therapy. Main measurement: how many patients' infections return within 12 months after surgery. This will be decided by a group of doctors who do not know what treatment the patient received. Other important measurements: serious adverse events; side-effects; quality of life; cost of treatment. Patients will be asked questions at their usual clinic visits, and will be given a questionnaire at the start of treatment and 1 year later.
