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 study aims to analyze the influence of the fourth ventricle compression technique in heart rate, respiratory rate, blood pressure, conductivity and thermal variability of the skin in healthy young adults.
Establish and validate biomarkers which improve the predictive value of current risk stratification models for patients benefiting from carotid revascularization, outperform existing biomarkers, and reach clinical application standards.
The investigators aim to test the feasibility of a pragmatic non-pharmacological strategy, that may prevent cognitive decline in patients with mild cognitive impairment. This strategy is based on five different interventions: cognitive training, physical activity, nutrition education, adaption to memory loss, diagnosis and correction of hearing impairment. A quasi-experimental study will be implemented in Porto (Portugal), including patients that fulfill all of the following criteria: a) age 18-85 years; b) Montreal Cognitive Assessment (MoCA) score greater than or equal to two standard deviations below the normative reference value for the corresponding age and education level in the Portuguese population OR diagnosis of Mild Cognitive Impairment, performed by a Neurologist, during the six previous months, considering the results of a neuropsychological battery; c) Cardiovascular Risk Factors, Aging and Dementia (CAIDE) Dementia Risk Score of at least six points. Patients who have any medical disability that contraindicates physical activity or have a lack of autonomy in daily activities will be excluded. The program will be implemented in groups of 10 participants, over a period of 10 consecutive months.
Mental disorders are among the most common causes of disability globally. Given the high prevalence of mental disorders (57.0%) in Azores islands (Portugal), local primary health care (PHC) services should encourage the implementation of complementary interventions for prevention of this type of disorders. New approaches, such as mind-body therapies, have been studied and recommended for prevention and treatment of numerous chronic diseases, particularly mental disorders. This study aims to evaluate the feasibility and effectiveness of a 6-months mind-body therapies (yoga, qigong and pilates), in users of Ponta Delgada Health Center (PDHC) with perceived distress, compared to a waiting list control.
Sedentarism is the fourth risk factor for worldwide mortality and morbility. Considering the high prevalence of sedentarism (57.0%) and obesity (30.5%) in Azores islands (Portugal), local primary health care (PHC) services should support the implementation of complementary interventions and the development of medical research in the area of active lifestyle promotion. This study aims to evaluate the feasibility and effectiveness of a 6-months functional training program (FTP), which includes a group nutrition counseling, in sedentary users of Ponta Delgada Health Center (PDHC), compared to a waiting list control.
The present study aims to optimize the use of systemic therapy relative to local tumor ablation in a prospective randomized clinical trial and to validate the existence and characterize the clinical and pathology phenotype of oligometastatic (OM) prostate cancer (OM-PCa). For local tumor ablation we propose to use the novel non-invasive and highly effective technique of Image-Guided Single Dose Radiotherapy (SDRT), which we showed is capable of conferring long-term local relapse-free rates in ≥ 90% of metastatic PCa lesions. Concomitantly, we will develop, validate and implement a diagnostic algorithm for OM-PCa and functionally characterize Prostate Cancer Stem Cells (pCSCs) from human samples to correlate their molecular phenotypes with tumor response to treatment. The long-term aim is to define the indications, standardization of treatment protocols and outcome for OM-PCa. Response assessment will be via local control, metastasis-free survival and overall survival rates. Cases displaying the clinical OM phenotype, as disclosed via long-term disease remission following tumor ablation, will represent the basis to identify the molecular signatures of OM-PCa. These signatures will be used to develop and validate an algorithm to predict the OM phenotype upfront and define the treatment strategy that may lead to cure.
The aim of this study is to evaluate the use of a poster containing information on dysphagia-specific food procedures at two levels: utility from the point of view of patients' caregivers, and impact on patients' health. Half the patients will have the poster placed in their room, whereas the other half will not.
This study is a single-center, prospective, non-blind, parallel-group, randomized controlled trial with an experimental and a control group with the aim of evaluating the clinical impact of a home-based falls prevention program using a new biofeedback system on community-dwellers older adults with fall risk in comparison with standard of care. The experimental group will perform a 12-week exercise program at home, under remote monitoring from a clinical team, whereas the control group will benefit from standard medical care currently in place at the participating primary care facility. The hypothesis is that the home-based falls prevention program will lead to a lower risk of falling than standard medical care.
The primary purpose of this study is to evaluate whether treatment with oral anticoagulation or oral anticoagulation and aspirin is better than aspirin alone in cardiovascular outcomes and saphenous graft patency in patients submitted to coronary artery bypass graft.
To investigate whether midazolam has any effect on postoperative pain in outpatient surgery, the investigators will assess the impact of different midazolam doses on pain scores 24h, 7 days and 3 months after ambulatory surgery. The investigators hypothesize that patients being administered higher midazolam doses will refer more pain.
