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.
This is an open-label, randomized, multicentre study to evaluate safety and preliminary efficacy of the human anti-CD19 antibody Tafasitamab in addition to R-CHOP (Rituximab, Cyclophosphamide, Doxorubicin, Vincristin, Prednison) or Tafasitamab and Lenalidomide in addition to R-CHOP in adult patients with newly diagnosed, previously untreated Diffuse Large B-cell Lymphoma (DLBCL).
Musculoskeletal pain can affect up to 40% of children and adolescents. Neck pain (NP) is one of the most prevalent painful conditions and evidence suggests that its prevalence has increased in recent decades in adolescents aged 16 to 18 years, from 22.9% in 1991 to 29.5% in 2011. Interventions based on pain neuroscience education have emerged as promising strategies in chronic pain conditions.In adults this intervention has been explored in many pain conditions, including musculoskeletal pain, but there is only one pilot study in adolescents with chronic NP and one case study in adolescents with fibromyalgia. Thus, the main objective of the present study is: (i) To compare the effectiveness of an education program based on pain neuroscience education and exercise versus exercise alone, in decreasing pain intensity in secondary school students with chronic and idiopathic NP immediately after the intervention and at 6 months. The secondary objectives are to: i) Compare the effectiveness of these programs immediately after the intervention and at 6 months in i) disability, ii) sleep, iii) pain catastrophizing, iv) fear of movement, v) self-efficacy, vi) central sensitization vii) the strength of the deep neck flexors and extensors muscles and stabilizers of the scapula; and viii) the pressure pain threshold between the two intervention groups; ii) Explore possible predictors of response to treatment.
A randomized multi-arm study evaluating the efficacy and safety of nivolumab versus placebo in combination with neoadjuvant (pre-surgery) chemotherapy and adjuvant (post-surgery) endocrine therapy in participants with high-risk, estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+, HER2-) early stage breast cancer.
Fit & Strong! (F&S!) is a non-pharmacological intervention designed for older people with osteoarthritis with proven efficacy. This program was developed and implemented among American patients. It is composed by two components: physical exercise with health education. In total, the program last eight weeks, and meets three times per week (24 sessions), for 90 minutes per session. The nationals and internationals statistics showed that Portugal has a high prevalence of OA, in particular in the knee or hip. Considering this fact and the negative impact in OA patients' lives the F&S! program was culturally adapted for Portugal, which constitutes its first formal adaptation to an international population and setting. Therefore, a randomized controlled trial was developed to the effects of F&S! among Portuguese older adults with lower-extremity OA, particularly, with respect to physical performance (walking speed, balance, lower body strength), pain, stiffness, functionality, physical activity, anxiety, depression and fear of movement. Participants were identified and referred from the electronic medical record maintained by general practitioners in Health Care Centers. Participants were randomly allocated to the experimental or to the control and were assessed three times (baseline, posttest and 4-months follow-up). Data analysis included descriptive statistics (medians and interquartile ranges) to describe participants' characteristics. The comparison between the experimental and the control group at baseline was performed using the Mann-Whitney U test for continuous variables and the Fisher test for categorical variables. Within each group, changes over time (pretest, posttest, follow-up) were analyzed using the Wilcoxon signed-rank test. Between group comparisons of differences in outcome variables between pretest, posttest and 4-month follow-up were analyzed using the Mann-Whitney U test.
Primary Objective: - To describe the clinical features and their severity at the time of diagnosis and their evolution over time in patients with confirmed chronic visceral and chronic neurovisceral forms of ASMD - To describe Clinician-Reported Outcomes (ClinROs) and Patient-Reported Outcomes (PROs) at enrollment and their evolution over time; disease severity at the time of diagnosis and its evolution over time Secondary Objectives: - To describe abnormal values in laboratory parameters and all values of specific clinical and imaging assessments at the time of diagnosis and their evolution over time - To study the use and applicability towards validation of a newly developed ASMD disease severity scoring system - To study the use and applicability towards validation of a newly developed ASMD PRO tool - To describe ASMD-related disease burden among patients with ASMD, caregivers, and healthcare resource utilization - To describe the association between patient demographics (eg, age, gender, race, Ashkenazi ancestry) and genotype with selected clinical features in patients with confirmed chronic visceral and chronic neurovisceral forms of ASMD
This study aims to study the barriers to flu vaccination among at-risk people at the Primary Health Care level in order to increase the vaccination rates as recommended by the World Health Organization.
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.
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.
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.
