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 objective of this multicenter, retrospective, cross-sectional, chart review study is to compare outcomes (disability, complications and mortality) of patients with large vessel occlusion stroke presenting at late time window selected by either Non-Contrast CT (NCCT) only, advanced imaging with CTP (Computed Tomography Perfusion), MRI (Magnetic Resonance Imaging), or medical management. Boston Medical Center (BMC) will serve as the main data coordinating site. Fifteen additional sites will seek local IRB approval or ethics approval. The aggregated de-identified data will be analyzed comparing types of interventions and outcomes by type of imaging or medical management.
Dementia is a leading cause of death and disability that was declared as one of the greatest health and social care challenges of the 21st century. Regular physical activity and exercise have been proposed as a non-pharmacological strategy in disease prevention and management. Multicomponent Training (MT) combines aerobic, strength, balance, and postural exercises and might be an effective training to improve both functional capacity and cognitive function in individuals with dementia (IwD). Nevertheless, data on the effects of MT in IwD are still limited and the extent to which IwD can retain improvements after an exercise intervention still needs to be elucidated. The aim of "Body & Brain" study is to investigate the effects of a 6-month MT intervention and 3-month detraining on the physical and cognitive function of IwD. Additionally, we aim to explore the impact of this intervention on psychosocial factors and physiologic markers related to dementia.
A Phase 3, multi-center, open-label study to evaluate the safety and tolerability of ampreloxetine in subjects with primary autonomic failures (MSA, PD, and PAF) and symptomatic nOH over 182 weeks.
This is an open-label, multinational, parallel 2-arm, randomized Phase 3 study evaluating the efficacy and safety of futibatinib versus gemcitabine-cisplatin chemotherapy as first-line treatment of patients with advanced, metastatic, or recurrent unresectable iCCA harboring FGFR2 gene rearrangements
The main objective of the study is to evaluate dose-exposure and safety of nintedanib in children and adolescents with fibrosing Interstitial Lung Disease (ILD).
Background: Hemorrhoidal disease is a common benign condition seen frequently in clinical settings. Rubber band ligation and sclerotherapy have proven to be the office-based procedures of choice in hemorrhoidal disease, with various studies reporting rubber band ligation as being more effective but also more painful and bleeding prone than sclerotherapy with liquid polidocanol. However, there are no studies comparing rubber band ligation and sclerotherapy with polidocanol foam, a new type of sclerosant agent that has already proved to be more effective and safer than liquid polidocanol in grade I hemorrhoidal disease. The present study was designed to establish the clinical effectiveness and safety of sclerotherapy with polidocanol foam compared with rubber band ligation. Methods: This randomized controlled trial includes patients with symptomatic hemorrhoidal disease grades I to III. The participants were randomly assigned (in a 1:1 ratio) to either rubber band ligation or sclerotherapy with polidocanol foam, stratified by grade of hemorrhoidal disease. During the intervention period the patients are submitted to one of the office-based procedures and, afterwards, in the follow-up period, evaluated every three months for a total period of one year. The efficacy outcomes include symptom resolution, number of treatment sessions needed to achieve therapeutic success and evolution of hemorrhoidal disease grade in the intervention period and, during follow-up, recurrence incidence. Primary safety outcomes include the occurrence of any complication related to the office-based procedures.
Randomized phase III, multicentre, open label clinical trial to compare pevonedistat in combination with azacytidine versus azacytidine alone, which can be considered a standard of care for patients with newly diagnosed acute myeloid leukemia not eligible for intensive chemotherapy (thus not eligible for an allogeneic hematopoietic stem cell transplant.
The trial is a multicenter, double-blind, randomized, placebo-controlled, dose escalation trial of weekly TransCon CNP administered subcutaneously in prepubertal children 2 to 10 years old, inclusive, with Achondroplasia.
The main aim of this study is learn more about long-term TAK-503 treatment in children and teenagers with ADHD for whom earlier stimulant treatment did not work. The study has two parts (A and B). In Part A, participants will take tablets of TAK-503, atomoxetine or placebo and in Part B TAK-503 tablets.
Peripheral intravenous catheterization (PIVC) is the most frequent invasive clinical procedure in a hospital setting, associated with significant complication rates for the patient, compromising their well-being, as well as the quality, safety, and efficacy of the care provided. The traditional approach to PIVC is considered reactive and ineffective, resulting in the exhaustion of the patients' peripheral venous access prior to consideration of other access methods and options (Moureau et al., 2012). Evidence suggests that the safety and effectiveness of patients with a peripheral catheter are also intrinsically associated with the adequacy of materials and technologies used in clinical contexts for vein selection, as well as for catheter insertion and maintenance care (Marsh, Webster, Mihala & Rickard, 2017). Several studies point to the inadequacy of the technologies and medical devices used in this area, enhancing the occurrence of complications such as infection, phlebitis, occlusion and accidental catheter removal (Braga, 2017; Costa, 2017; Nobre & Martins, 2018). The project investigators aim to determine whether the use of a PIVC pack will significantly reduce associated complications when compared with the usual care. Additionally, the research team aims to determine if the use of a PIVC pack will reduce the number of insertion attempts and overall procedure time, as well as improving patient and provider satisfaction.
