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 goal of this project is to study the influence of child-centered communication on children's anxiety, satisfaction and the use of anesthesia for MRI
The main objective was to demonstrate the existence and importance of hypercoagulability in patients with IBD, by determining the prevalence of changes in coagulation parameters and evaluating the impact of these changes on the occurrence of thromboembolic events.
Introduction: The death of a partner is a frequent and very stressful critical life event in later life. Grief and psychological distress after the loss of a partner are normative reactions. However, 10% of individuals are less able to cope with bereavement and show symptoms of disturbed or prolonged grief, or adaptation problems. Focus groups have concluded that Portuguese older adults who lost their partner avoid and downplay the grief process, not seeking help when needed. LEAVES is an interactive self-help online programme founded in the task model of mourning and the dual-process model of coping with bereavement that supports older adults who have lost their partner in dealing with and preventing prolonged grief. As part of an international consortium with two more trial centres, LEAVES-PT will carry out a 10-week pragmatic randomised two-armed parallel-group controlled trial to determine the effectiveness of LEAVES vs. usual care in reducing grief in community-dwelling Portuguese adults over 55 years who have lost a partner. Besides the clinical evaluation, a cost-effectiveness analysis will be carried out. Methods: Adults over 55 years, who have lost a partner and are registered with a primary care service in Lower Alentejo, Portugal will be invited to participate and, after screening for eligibility, a minimum of 100 will be randomised to one of two arms: usual care + LEAVES online service or usual care (1:1). The intervention will last for 10 weeks and follow-up will last for a further 10 weeks (20 weeks). Grief is the primary endpoint and it is measured by the Texas Revised Inventory of Grief. Linear mixed models will be used to determine the effectiveness of LEAVES on grief symptoms using the intention-to-treat principle. Due to several recruitment barriers the study ultimately became a pre-post study with only 1 intervention arm.
Background: Hyperglycemia is a risk factor to disease development, namely, diabetes mellitus. The blood glucose level management, particularly on post-prandial period has an important role in the prevention of different diseases. Ginger is a specie that has been demonstrated a benefit effect on glycaemia on diabetes. Aim: The aim of this study was 1) to investigate the effects of ginger infusion in the glycaemic response in nondiabetic adults; 2) to evaluate total phenolic content the antioxidant activity of Ginger (Zingiber officinale Roscoe) aqueous extracts. Methodology: 24 nondiabetic subjects were randomly allocated into two groups: intervention group (GI; n=15) and control group (GC; n=15). An oral glucose solution (OGTT) and an OGTT following ginger extract solution were administrated in control and intervention groups, respectively. Blood glucose levels were measurement at fasting and after 30, 60, 90 and 120 minutes after interventions in both groups. Total phenolic content and flavonoids compounds determination of the aqueous ginger extract was determined according to Prabha method. Antioxidant activity was also measured through ABTS method and free radicals inhibition capacity. Repeated Measures ANOVA of mixed type and independent samples t-test were used in statistical analysis.
The #KindGirlsInACTion project started in 2017 and developed and implemented a psychotherapeutic intervention program in Portuguese female adolescents. This program aimed to improve the overall quality of life and well-being of the participants, and specifically to promote a qualitative improvement in body image and interpersonal relationships, through the promotion of self-compassion, compassion and psychological flexibility. #KindGirlsInACTion is a school-based program, with 9 sessions over 9 weeks. It is essentially practical and interactive, with exercises created specifically for the program, as well as the regular practice of mindfulness.
Some studies show that different types of threads in tapered implants result in differences in primary stability. The aim of this study is to a perform a prospective, controlled, randomized clinical trial comparing primary and secondary stability between long and standard thread implants in the treatment of partial edentulous patients.
Baobab fruits have been traditionally used in Africa due to its therapeutic proprieties attributed to it high polyphenol content. The aim of the study was to investigate the effect of baobab fruit on postprandial glycaemia on healthy adults and to measure its bioactive compounds and antioxidant activity. The study was conducted on 31 healthy subjects. The participants were randomly allocated in control group (oral glucose tolerance test (OGTT); n = 16) and in intervention group (OGTT followed by administration of 250 ml baobab aqueous extract (BAE); n = 15). Total phenols, proanthocyanidins, hydrolysable tannins and antioxidant activity (FRAP, DPPH, ABTS and inhibition of O2•- and NO• methods) were quantified. Repeated Measures ANOVA of mixed type and Independent samples t-test were used.
Many cancer survivors are at risk for cardiovascular disease (CVD); it is therefore important to identify patients at increased risk for cardiotoxicity, especially in the setting of CVRF or pre-existing CVD, and to design personalized interventions to prevent cardiovascular morbidity. In this background, cardio-oncology rehabilitation frameworks for specific cancer patients have been proposed. Given potential beneficial effects of exercise among cancer patients (including those at higher risk of CVD), data pertaining to optimal program designs are of paramount contemporary importance. Thus, the aim of this study is to compare the impact of a Cardiac Rehabilitation Program (CRP) model versus a community-based exercise intervention plus usual care on cardiorespiratory fitness (CRF), physical function domains and CVRF control in adult cancer survivors who have been exposed to cardiotoxic cancer treatment and/or with cardiovascular medical background. Study outcomes will be assessed at baseline (M0) and after an 8 weeks-intervention (M1), comprising maximal aerobic capacity (peak oxygen uptake), muscular strength, neuromuscular function, single CVRF control including physical activity measurements and psychosocial parameters, health-related quality of life, fatigue, health literacy, inflammatory response and feasibility metrics; an economic evaluation will provide quantitative comparison, for a cost-effectiveness analysis
This study compares the effectiveness of a new layered thermal insulation system (SIT-3c) versus the traditional thermal body protection (warmed forced air system) for patients under total knee arthroplasty, during the intra-operative phase.
This retrospective multi-center, multi-national cohort study is to validate the European Bone and Joint Infection Society (EBJIS) Definition of Prosthetic Joint Infection. Specifically, it is to analyze the outcome of the Infection Likely group and compare it to the Infection Unlikely group as well as other subgroups within previous validated definitions (Musculoskeletal Infection Society (MSIS)/International Consensus on Musculoskeletal Infection (ICM) 2013 and ICM 2018).
