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 authors hypothesize that in patients with iron deficiency anemia or gastrointestinal bleeding, pan-intestinal capsule endoscopy is a safe and well tolerated procedure that may improve diagnostic yield comparatively to the current standard invasive colonoscopy.
This study is open for men and women with a liver disease called nonalcoholic steatohepatitis (NASH) and liver fibrosis. The purpose of the study is to find out whether a medicine called BI 456906 helps patients with NASH and liver fibrosis. The study tests 3 different doses of BI 456906 to find the dose that helps best. Participants are put into 4 groups randomly, which means by chance. There are 3 groups that each receive a different dose of BI 456906 and there is 1 group that receives placebo. BI 456906 and placebo are given as an injection under the skin once per week. The placebo injection looks like the BI 456906 injection but does not contain any medicine. Participants are in the study for a little over 1 year (60 weeks). During this time, they visit the study site several times and have some video calls in addition. At the visits, the study doctors take different measurements. To see whether the treatment works, the doctors take a very small sample of liver tissue (biopsy) from each participant at the start and at the end of the study. They also examine the liver by ultrasound and MRI. The doctors also regularly check the general health of the participants.
This study compares insulin icodec (a new insulin taken once a week) to insulin degludec (an insulin taken once daily which is already available on the market) in people with type 2 diabetes. The study will look at how well insulin icodec taken weekly controls blood sugar compared to insulin degludec taken daily. Participants will either get insulin icodec that participants will have to inject once a week on the same day of the week or insulin degludec that participants will have to inject once a day at the same time every day. Which treatment participants get is decided by chance. The insulin is injected with a needle in a skin fold in the thigh, upper arm or stomach. The study will last for about 8 months. Participants will have 17 clinic visits and 13 phone calls with the study doctor. At 8 clinic visits participants will have blood samples taken. At 4 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit. Participants will be asked to wear a sensor that measures their blood sugar all the time in 3 periods for a total of 13 weeks (about 3 months) during the study. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.
Introduction: Traditionally, White Light Endoscopy (WLE), enhanced by biopsies following the updated Sydney system guidelines, has been the benchmark for diagnosing and classifying gastric preneoplastic conditions. Nevertheless, the pronounced interobserver variability and the often weak correlation between endoscopic observations and histopathological results have driven the increasing adoption of virtual chromoendoscopy (VCE). VCE technologies have demonstrated greater effectiveness in identifying these conditions compared to WLE, with Narrow Band Imaging (NBI) being particularly notable. Significantly, NBI has played a key role in validating the Endoscopic Grading of Gastric Intestinal Metaplasia (EGGIM) system. However, data on the effectiveness of other VCE technologies in this domain is relatively sparse in Europe, specifically with Blue Light Imaging (BLI), despite the promising diagnostic performance demonstrated with this technology. Primary aim: to assess the diagnostic accuracy of BLI and to externally validate the applicability of EGGIM classification for staging GIM. Material and methods: a multicentric cohort study will be performed involving centres from two European countries (Portugal, Italy). Consecutive patients performing upper gastrointestinal endoscopy will be evaluated by WLE and BLI. Random biopsies or targeted plus random biopsies will be performed in order to determine de accuracy of BLI system to detect and stage GIM. Expected results: We anticipate that BLI would enable us to assess the extension of GIM without the need for biopsies. If observed, this would overall improve the upper GI endoscopy accuracy.
Many clinicians continue to rely on subjective evaluation in making decisions about the adequacy of neuromuscular function before tracheal extubation rather than using quantitative monitoring. The aim was to compare the sugammadex dose as suggested by senior anaesthesiologists (SSD) based on clinical experience versus the dose determined by quantitative monitoring (QSD) to determine if the subjective dose was appropriate.
Retinal diseases are currently the leading cause of legal blindness in the developed world. Among these disorders, age-related macular degeneration (AMD) is one of the most prevalent conditions in individuals over 55 years of age. Late AMD, the most severe presentation of the disease, clinically manifests as either geographic atrophy (dry form) or choroidal neovascularization (CNV) (wet form). Although patients with wet AMD only represent 10% of the total cases, CNV is the main and most serious cause of central vision loss. At present, the treatment of wet AMD comprises intraocular injections of certain antiangiogenic agents which act by blocking VEGF (vascular endothelial growth factor). No effective treatment is yet available for dry AMD, though the AREDS (Age-Related Eye Disease Study) has shown that the administration of antioxidant supplements is able to slow progression of the disease. Such vitamin supplements are also indicated in patients who already have severe AMD (both exudative and atrophic) in one eye, since the risk of progression in these cases is high. Recent studies involving new antioxidant and antiangiogenic molecules such as resveratrol, present in grapes and wine, have also revealed great efficacy in slowing the progression of advanced AMD. Hydroxytyrosol is another polyphenol with important antioxidant and antiinflammatory effects in the RPE. Considering the above, the present randomized, multicenter interventional study involving Spanish and Portuguese patients with unilateral wet AMD was designed to compare the effects of two different nutritional supplements: one containing the antioxidants and minerals recommended by the AREDS at doses that can be used in the European Union (Theavit), and the other comprising these same substances plus omega-3 fatty acids (lipidic antioxidant), lutein (pigment protecting against light-induced damage) and resveratrol (antioxidant and antiangiogenic agent) (Retilut).
Lip support plays an important role in facial esthetics, being a relevant factor when realizing full arch implant supported rehabilitations. However, there is a lack of research on the three dimensional impact of such restorations.
The primary objective of this post market clinical follow-up (PMCF) investigation is to confirm the safety and performance of Avance®Solo and Avance®Solo Adapt NPWT Systems in low to moderate exuding chronic wounds when used in accordance with the Instructions for Use, for up to 28 days.
Heads of all psychosomatic, psychiatric and psychological consultation and liaison (C&L) services in acute care hospitals across all participating countries will be contacted and asked to participate in this international cross-sectional online survey. The survey consists of questions about care structures and their utilisation that psychosomatic, psychiatric and psychological C&L services have established in acute hospitals in the context of the COVID 19 pandemic.
This study is open to adults with diabetic kidney disease. The purpose of the study is to find out whether a medicine called BI 685509 improves kidney function. Three different doses of BI 685509 are tested in this study. Participants get either one of the three doses of BI 685509 or placebo. It is decided by chance who gets which BI 685509 dose and who gets placebo. Participants take BI 685509 or placebo as tablets 3 times a day. Placebo tablets look like BI 685509 tablets but do not contain any medicine. Participants continue taking their usual medicine for diabetes and kidney disease throughout the study. Participants are in the study for about 7 months. During this time, they visit the study site about 11 times. Where possible, about 6 of the 11 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Kidney function is assessed based on the analysis of urine samples, which participants collect at home. At the end of the trial the results are compared between the different doses of BI 685509 and placebo. During the study, the doctors also regularly check the general health of the participants.
