The objective of this clinical trial is to evaluate, in clinically healthy young omnivores, whether excluding red and processed meat from their diets for four weeks results in: * measurable changes in arterial structure and function; * measurable changes in key metabolic paramet…

Clinical trials are studies that test new treatments to see if they work and are safe for people with certain illnesses. Phase I clinical trials are the earliest stage of testing, where researchers give a new treatment to a small group of people to see if it's safe and how much o…

This project is focused on Veteran patients 65 and older with chronic pain. In this project, the investigators will understand the impact of a contextual patient generated health data (PGHD). Contextual PGHD are data about what is important to patients, information about the Vete…

The investigators will examine the relationship between nicotine flux, nicotine form, and the rate and dose of nicotine delivery. Participants will puff on electronic nicotine delivery system (ENDS) devices under conditions that differ by flux and form, while arterial blood is sa…

This is a community-engaged research project that aims to identify and pilot test interventions that may reduce substance use stigma among professionals at primary care sites serving patients who might be exposed to HIV or are living with HIV. Our goal is to develop a multi-level…

The purpose of the study is to investigate the effects of pulse consumption versus no pulse consumption on the gut microbiome, meal satiety, and short-chain fatty acid metabolomics.

There is scientific evidence suggesting that tobacco use during pregnancy is associated with several adverse effects in newborns, including low birth weight, respiratory complications, severe neonatal morbidity, perinatal death, and a higher risk of infections and neurological pr…

Mechanical ventilation is a life-saving treatment frequently applied in intensive care unit (ICU). Nonetheless, by putting at rest the respiratory muscles, it can lead to respiratory muscle weakness and atrophy, which are accompanied by prolonged duration of mechanical ventilatio…

The purpose of this study is to determine the feasibility of conducting a randomized controlled trial (RCT) with melatonin for treatment of delirium in critically ill adult patients. From a feasibility perspective, the investigators believe that the proposed design will achieve t…

To explore the effectiveness of a 12-week resistance exercise programme plus or minus an oral nutritional supplement on the nutritional status of community-dwelling older adults who receive home care and are at risk of sarcopenia.

The goal of this clinical study is to compare the effectiveness of different methods for decontaminating dental implant surfaces in the treatment of peri-implantitis. The main question it aims to answer is: Which combination of an antiseptic solution and an air-polishing powder …

In this study, participants will be asked to wear a wrist alcohol biosensor for 30 days and report alcohol use using a ecological momentary assessment (EMA) app. A subset of the sample will be micro-randomized to test two engagement strategies--reciprocity and personalized feedba…

Monocentre, non-randomized, non-blinded, open-label interventional study to identification of relevant changes in molecular biology in proteome, phosphoproteome, lipidome, epigenome and transcriptome in pretransplant kidney biopsy samples in patients preconditioned by different d…

Emerging data suggest the gut microbiota regulates multiple mechanisms related to vascular aging, but no intervention targeting the gut microbiota has been tested in older adults without cardiovascular risk factors or cardiovascular disease. Early human data suggest an increase i…

Individuals with mild cognitive impairment are often physically inactive and at risk for progressing to dementia. Physical inactivity is considered a modifiable risk factor for dementia. Therefore, interventions must be developed to foster sustainable improvement in daily physica…

This study aims to compare the diagnostic accuracy of rapid antigen detection tests (RDTs) for SARS-CoV-2 using nasal swab insertion depths of 2 cm versus 4 cm. The study is an investigator-initiated, randomized clinical trial conducted at a public COVID-19 test center in Copenh…

Patients with post-stroke hemiplegia frequently exhibit balance impairments driven by multiple pathophysiological mechanisms. Although the role of core musculature in maintaining normal posture and balance is well established, and the benefits of core stabilization exercises have…

This observational cross-sectional study aims to investigate the relationship between patient and therapist perceptions of safe ambulation and objective clinical outcomes in individuals with incomplete spinal cord injury (iSCI). Adults with iSCI at T3 or lower levels (ASIA C or D…

The overall purpose of this study is to describe the cellular composition of the human appendix and its gene expression using scRNAseq and scATACseq methods. This will potentially provide is with a complete and detailed map of the appendix´ immunological properties and its role i…

This project will investigate the effect of spinal cord transcutaneous stimulation on blood pressure in individuals with a chronic spinal cord injury who experience blood pressure instability, specifically, orthostatic hypotension (a drop in blood pressure when moving from lying …
