Clinical trials

This is an observational, cross-sectional study with a control group, with the general objective of developing and evaluating a national database, unprecedented in Brazil, containing clinical, epidemiological, motor, and non-motor aspects of Parkinson's disease (PD). The database will be open and accessible to national and international researchers in order to contribute to the advancement of research related to PD. The aim is to collect data, in a paired way, from a control group and an experimental group. Data collection will include the application of questionnaires, the execution of motor activities, and clinical scales. Information that can identify the participants will be removed from the database for later storage in a repository. Quantitative, qualitative, and descriptive variables from the database will be estimated in order to characterise and contrast the groups studied. The results of this study will contribute to a better characterization of the staging of PD as a function of the epidemiological, motor, and non-motor aspects evaluated, as well as to the development of technologies and methods that can be applied in clinical practice.

The goal of this pilot randomized clinical trial is to evaluate the efficacy of a mindful eating intervention ("Eat for Life") on eating behavior, body image, and mental health in female nutrition students. The main questions it aims to answer are: Does a mindful eating intervention reduce disordered eating behaviors in female nutrition students? Does the intervention improve body appreciation, mindfulness levels, and mental health? Researchers will compare an active control group receiving nutritional guidance to an intervention group participating in the "Eat for Life" mindful eating program to see if the mindful eating intervention reduces disordered eating behaviors and improves overall psychological well-being and body appreciation. Participants will: Complete online questionnaires evaluating eating behavior, mindfulness, mental health, and body image at three distinct time points: before the intervention (baseline), post-intervention, and at a 3-month follow-up. If assigned to the intervention group, attend 12 weekly face-to-face mindful eating sessions lasting approximately two hours each. If assigned to the active control group, receive weekly informative leaflets via WhatsApp with nutritional guidance based on the Dietary Guidelines for the Brazilian Population for 12 weeks

To evaluate the effect of omega-3 supplementation combined with whey protein intake on lean mass and strength gains in older adults performing resistance exercise. Participants will be randomized into the 4 groups. The placebo group will receive 4 g per day of corn oil and 40 g per day of maltodextrin. The omega 3 + placebo group will receive 4 g per day of fish oil and 40 g per day of maltodextrin. The whey protein + placebo group will receive 40g per day of whey and 4g per day of corn oil. The omega 3 + whey group will receive 4g per day of fish oil and 40g per day of protein. All will perform the same exercise protocol for 12 weeks
