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 research aims to evaluate the effect of cognitive stimulation (CS) on the functioning of the prefrontal cortex (PFC), seeking an analysis of both cerebral hemodynamics in neuroplasticity and aspects related to the initiation of neurodegenerative processes. The intervention presents an individual format and the participants are elderly without or with neurocognitive disorders (NCD). Concretely, to assess the effects of individual CS on global cognition, and mood, as well as to analyze neuronal activity with oxygenation, volume and blood flow in the brain, evaluating the impact of cognitive stimulation on brain hemodynamics. Participants in the intervention group receive two 45 min-session of CS per week for 12 weeks in addition to their treatment as usual. Participants in the control group will maintain their treatment as usual.
The purpose oh this study is to verify the immediate effects of dynamic cupping on median nerve's mechanosensitivity, measured by the upper limb neurodynamic test 1 (ULNT1) in healthy participants.
The purpose of this study is to evaluate the efficacy of eptinezumab in participants with episodic Cluster Headache (eCH)
This is a phase 3, multicenter, randomized, double-blinded, placebo-controlled, parallel-group trial to evaluate the efficacy, safety, and effect on QoL/PRO of efgartigimod PH20 SC treatment in adult patients with primary ITP.
This Phase 3 study will evaluate the efficacy of the investigational agent MRTX849 (adagrasib) versus docetaxel in patients who have been previously treated for metastatic NSCLC with a KRAS G12C mutation.
Primary Objective: To evaluate the efficacy of dupilumab as assessed by the reduction at Week 24 in sinus opacification on computerized tomography (CT) scan in the dupilumab group only Secondary Objectives: - To evaluate the efficacy of dupilumab as assessed by the reduction at Week 24 in sinus opacification on CT scan and sinus total symptom score (sTSS) compared to placebo - To evaluate the safety and tolerability of dupilumab in CRSsNP patients compared to placebo - To evaluate the pharmacokinetics (PK) of dupilumab in CRSsNP patients compared to placebo - Assessment of immunogenicity to dupilumab over time compared to placebo
The main objective of this study is to evaluate the efficacy of ALIS (amikacin liposome inhalation suspension) + background regimen (azithromycin [AZI] + ethambutol [ETH]) compared to the ELC (empty liposome control) + background regimen on participant-reported respiratory symptoms at Month 13.
Background: Hemorrhoidal disease is extremely frequent in the adult population and, as a benign pathology, the treatment should be guided by the patient's symptoms. Treatment of hemorrhoidal disease includes a conservative approach, office-based treatments and surgery. This study is aimed to evaluate and compare the efficacy and safety of the treatment of hemorrhoidal disease with non-surgical office-based method polidocanol foam sclerotherapy (SP) and the surgical technique doppler-guided hemorrhoidal artery ligation with recto-anal repair. Methods: Prospective, unicentric study including patients with symptomatic hemorrhoidal disease grade II and III refractory to conservative therapy, submitted either to SP (n=24) or to HAL-RAR procedure (n=21), during a recruitment period of 6 months. Patients were evaluated for efficacy (Sodergren's scale of symptoms and severity of bleeding) and safety (complications and implication in personal and professional life), up to one month after treatment. In follow-up period (6 months) participants were evaluated for hemorrhoidal disease recurrence.
The current understanding of dental caries has not been completely transferred into the clinical practice to control caries lesion progression (severity / activity) and the individual risk of caries. This situation led to the development of the CariesCare International CCI Caries Management System (2018), derived from ICCMS™- International Caries Classification and Management System (2012) and the ICDAS - International Caries Detection and Assessment System (2002) in a consensus among more than 45 cariologists, epidemiologists, public health professionals, researchers and cliniciansfrom all over the world. The consensus aimed to guide dentists and dental teams in clinical practice, facilitating the control of the caries process and the maintenance of oral health in their patients. The general lack of implementation of an updated management of dental caries is evident in Colombia, in the survey of 1094 clinicians, teachers and students, failures were reported to adopt related behaviours, motivation barriers (remuneration), opportunity (in terms of relevance, physical/infrastructure resources, time) and training. As an additional barrier, the Colombian Chapter of the Alliance for a Cavity-Free Future (ACFF), evidences the absence of a facilitating Oral Health Record (OHR), this situation lead to stablish a new Alliance between the Ministry of Health and Social Protection (MSPS) and the AFLC to develop an inter-institutional consensus at the national level, of a clinical history for diagnosis and management of lesions and caries risk. Finally, 55 institutions participated in this consensus, and we have just finished a pilot test of the forms to submit a proposal for national standardization from the MSPS. The aim of this multicentre case series is to assess after 3, 6 and 12 months in children oral health outcomes, caregivers' satisfaction and in dentists' process outcomes, after the implementation of the CCI system adapted for the COVID-19 era -non-aerosol generating procedures. Oral health outcomes will be evaluated in terms of: - Effectiveness of CCI to control bacterial plaque, caries progression and caries risk, and to achieve behavioural change in oral health in children. - Acceptance of CCI caries management adapted for COVID-19 through Treatment Evaluation Interventory in dentists, and in children/parents through satisfaction questionnaire. - Costs of CCI adapted for caries management, in economic terms, number and appointment time.
This is a study for participants with a type of blood cancer called mantle cell lymphoma (MCL). The main purpose is to compare pirtobrutinib (LOXO-305) to other drugs that work in a similar way that have already been approved by the United States Food and Drug Administration (US FDA). Participation could last up to two years, and possibly longer, if the disease does not progress.
