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 researchers' implement and measure the effects of a singing group intervention program for older adults, with an RCT design, in a natural context, on the health, well-being and cognitive function of older adults.
This non-randomized controlled trial with a control group aimed to assess the efficacy of a 20-session individualized Compassion Focused Therapy-based intervention, the PSYCHOPATHY.COMP, in reducing psychopathic traits (primary outcomes), aggression, shame, emotion regulation problems, and fears of compassion, as well as in increasing social safeness, self-compassion, and compassion towards others (secondary outcomes). The PSYCHOPATHY.COMP's impact on psychophysiological (i.e., Heart Rate/Heart Rate Variability) and behavioral indicators (i.e., number disciplinary infractions and number of days in punishment) were also tested, in order to ascertain if changes observed in self-report questionnaires were reflected in more adjusted psychophysiological and behavioral patterns. Mental Health disorders, as well as the number of Conduct Disorder criteria, were also tested as moderators of treatment effects.
Study 20170703 is a phase 4, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy and safety of erenumab against placebo in participants with chronic migraine (CM) who have a history of at least 1 preventive treatment failure and are diagnosed with medication overuse headache (MOH).
The FES-ABLE project results from an Iberian partnership and aims to evaluate the impact of an intervention based on a functional electrical stimulation (FES) prototype on the upper limb movement quality during functional tasks. The results of this project will contribute to the definition of the therapeutic window of FES to improve upper limb function in stroke rehabilitation.
Introduction: The white coat is a physician attire worn since the antiquity time. Several studies in other countries have shown that it influences doctor-patient's relationship and that there is some kind of preference over what a doctor should wear. In Portugal there are few data on this subject. Objectives: Investigate the influence of the white coat on satisfaction, confidence and empathy in relation to patients. Secondly, its impact on what patients perceive about medical knowledge, patients' opinions about medical clothing, and the level of satisfaction and comfort of physicians in consultation with or without the use of a white coat. Methods: An interventional study with a quasi-randomized representative sample of the population attending the health centers belonging to ARS Centro, consisting of 286 participants. The investigators collaborated with 16 doctors, male and female and of different ages which usually wore white coat in their medical appointments. The investigators included the first and last patients in consultation every day for 10 consecutive days, and every other day the doctor consulted with the use of a white coat or without the use of a white coat. At the end of the consultation, a questionnaire was distributed to the patient. This questionnaire had simple questions with a Lickert scale response, the portuguese version of the scale "Trust in physician" to assess the trust in the physician, both globally and in the medical-patient's relationship and their medical competences, and the JSPPPE-VP scale to evaluate empathy. A questionnaire was also distributed to the physician in which the doctor indicated what type of attire that used on that appointment and how satisfied and comfortable was with the consultation.
Induction of anesthesia and the knee-chest position are associated with hemodynamic changes that may impact patient outcomes. Changes from baseline in cardiac output and other hemodynamic variables following induction of anesthesia and knee-chest positioning were compared. Propofol plasma concentrations were also measured after induction of anesthesia and after the knee-chest position. The aim of this study was to assess whether planned reductions in target-controlled infusion propofol concentrations attenuate the hemodynamic changes associated with anesthesia induction and knee-chest position. The secondary aim was to quantify the variation in propofol measured plasma concentrations (Cm), both after induction and after KC positioning, and correlate them with predicted concentrations (Cp) by the Schnider Pk model.
The objective of this study was to collect data both retrospectively and prospectively in order to evaluate the long-term outcomes, durability of effect, and real-world treatment patterns following treatment with Cladribine Tablets or placebo in participants with multiple sclerosis (MS) who were previously participated in the parent studies (ORACLE MS and CLARITY/CLARITY-EXT).
The study uses a case-control design that examines the differences in types of exposures between cases defined with a pathological confirmation of GC diagnosis, and controls, defined as patients to whom a gastroscopy was indicated and confirmed absent of GC i
This study will evaluate the efficacy and safety of OZURDEX in patients with Diabetic Macular Edema when used in a real world setting in Spain and Portugal.
This investigation will focus on the use of EDDY tips, because it is known that the complete debridement of the canal is very difficult, which leads to an accumulation of tissue debris, bacteria and their products, resulting in persistent periradicular inflammation. So, it's of great importance, the study of other approaches of cleaning and disinfecting the root canal, which at the same time, may produce a lower risk of postoperative pain. The above mentioned topics have never been analysed simultaneously with the use of EDDY tips, and the evaluation of the postoperative pain was never addressed. This research is of great clinical interest, due to the complexity of root canal system, with isthmuses, ramifications and dentinal tubules, that make the total elimination of bacteria impossible, even with the best clinical protocols, because the irrigants cannot penetrate the dentinal tubules, and the postoperative pain is an exhausting factor for patients. Therefore, a new protocol, with better disinfection rate and less postoperative pain, will be able to increase the success rate of endodontic treatments, allowing to save condemned teeth.
