There are about 3150 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 study aims to analyze the efficacy of diaphragm stretching technique on symptomatology in young adults with nonspecific low back pain.
Phase II, randomized, Active-controlled open label trial for treatment of high risk, HR-/HER2- (triple negative) breast cancer, with two sequences of neoadjuvant chemotherapy on a background of pembrolizumab
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
This study aims to i) To characterize the functional status and explore the determinants of functional status decline of people with IlD ii)To determine the measurement properties of functional status instruments in people with Interstitial lung diseases (ILD) iii) To identify the impact of ILD and the participants' perspectives on functional status through interviews iv) Explore the progression of functional status progression in people with ILD and v) Develop a multidimensional index, incorporating functional status parameters, to predict mortality in people with ILD. Patients with ILD will be recruited via the pulmonology services at hospitals, namely from Centro Hospitalar de Vila Nova de Gaia/Espinho (CHVNG/E), Centro Hospitalar do Baixo Vouga (CHBV) and Centro Hospitalar de Entre o Douro e Vouga (CHEDV). Sociodemographic, clinical characteristics (i.e., smoking habits, vital signs and symptoms), anthropometric (i.e., height and weight to compute body mass index) and general clinical data (i.e., medication, oxygen therapy, non-invasive ventilation, acute exacerbations, hospitalizations and number of hospital admissions in the last month and year, length of stay), as well as prior and follow-up spirometric measurements and arterial blood gas will be collected from clinical records for patients' characterization. Mortality and rehospitalizations will be explored during the study period. Peripheral muscle strength, functional status, daily physical activity, self-reported symptoms, functional status, impact of the disease and health-related quality of life. Qualitative data from interviews. The assessments will be conducted at 6 time points: baseline and 1 week after for instrument validation, followed by assessments every 6 months for 2 years. It is expected that: i) Functional status limitations can be comprehensively identified and measured in individuals with ILD. ii) Some measures are valid and reliable indicators of functional status in individuals with ILD. iii) Different profiles of functional status progression will be identified in individuals with ILD, including stable, slow, and fast decline. iv) A multidimensional index incorporating functional status will improve the accuracy of predicting mortality and outperform the predictive ability of the current GAP Index.
Memory complaints are a common symptom among Subjective Cognitive Decline, Mild Cognitive Impairment and Alzheimer disease. Indeed, episodic memory and Alzheimer disease are highly sensitive to aging. Many brain areas become active when we remember an event from the past. The precuneus, part of the posterior system of default mode network, has been identified as a central node of episodic memory retrieval and a central node in various psychiatric and neurological disorders, such as Alzheimer disease. Age-related changes have been consistently found in the default mode network connectivity, occurring within its posterior areas and with the reduction of connectivity between anterior and posterior subnetwork. It has also been found that aging is associated with decreased functional connectivity in the precuneus and posterior cingulate of the default mode network. Furthermore, γ-Aminobutyric acid (GABA), which plays an essential role in regulating brain activity and modulating the default mode network, shows a decrease throughout the normal course of aging, in Mild Cognitive Impairment and Alzheimer disease. It was also verified a link between cognitive decline and the dysfunction of the inhibitory activity of GABAergic interneurons, particularly parvalbumin-positive interneurons, that play a role in control local circuitry, brain networks and memory processing. Parvalbumin interneurons are the fast-spiking interneurons that generate and maintain gamma frequency. Gamma band has been associated with the encoding and retrieval of episodic memory. Impairments of gamma oscillations have been observed in healthy aging, Mild Cognitive Impairment and Alzheimer disease. By identifying these functional connectivity changes, non-invasive neuromodulation techniques may offer a new strategy for improving cognitive functions. Transcranial Alternating Current Stimulation (tACS) is a form of non-invasive brain stimulation that modulates cortical activity by applying weak, oscillating electrical currents to the cortex via two or more scalp electrodes. By using alternating currents, it is possible to simulate the rhythmic pattern of electrophysiological activity of the brain. tACS can interact with neural firing at behaviorally relevant frequencies linked to memory. In this randomized, double-blind, sham-controlled, cross-over study, the investigators will evaluate whether stimulation with gamma tACS on the precuneus can improve episodic memory in healthy older adults.
This study is a phase III, randomized, open-label, international, multicenter, interventional trial, designed to compare the efficacy and safety of mosunetuzumab in combination with lenalidomide versus anti-CD20 monoclonal antibody (mAb) plus chemotherapy in patients with previously untreated FLIPI 2-5 follicular lymphoma.
This study aims to evaluate the clinical, imaging results of endovascular revascularization of the aorto-iliac sector in comparison with aortobifemoral bypass and the hybrid approach, in patients with atherosclerotic disease of the iliac sector classified as type C and D by the TransAtlantic Inter-Society Consensus (TASC II
The goal of this study is to assess the safety and effectiveness of Dostarlimab compared to Placebo in adult participants with HNSCC (Head and Neck Squamous Cell Carcinoma)
To overcome the lack of knowledge regarding the impact of different "living low, training high" methods on swimming performance, a 4-week intervention will be carried out to determine and compare the effects of three Repeated Sprints in Hypoxia (RSH) methods with each other and with a control group. Our goal is to characterize and compare the adaptations in swimming performance and in cardiorespiratory, metabolic, and muscle oxygenation responses that can arise after a 4-week training period of RSH and RSH-voluntary hypoventilation (VHL) performed in a ski-ergometer.
