There are about 2320 clinical studies being (or have been) conducted in Chile. 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 aim of this study will be to evaluate the effect of reduced dentin etching time on the 6- and 12-months clinical performance of two universal adhesive systems used as etch-and-rinse application mode in non-carious cervical lesions (NCCLs). Materials & Methods: 140 restorations will be randomly placed in 35 subjects according to the following groups: SUP5 (Scotchbond Universal Plus adhesive on dentin etched for 5 seconds); SUP15 (Scotchbond Universal Plus adhesive on dentin etched for 15 seconds); GBU5 (Gluma Universal Bond adhesive on dentin etched for 5 seconds); GBU15 (Gluma Universal Bond adhesive on dentin etched for 15 seconds). All groups will be light-cured for 10s/1,000 mW/cm2. A resin composite will be placed by applying three increments and each one will be light cured for 20s/1,000 mW/cm2. The restorations will be finished immediately with fine diamond burs and polishers. The restorations will be evaluated at baseline and after 6- and 12-months by using the FDI criteria. The following outcomes will be evaluated: retention, marginal staining, marginal adaptation, post-operative sensitivity and recurrence of caries. The differences among the groups will be calculated using Friedman repeated measures analysis of variance rank (α = 0.05).
Falls are unplanned events resulting in contact with a lower surface. They are common in older adults, affecting one in three individuals over 65 years old. They have serious consequences, ranging from physical injuries (fractures, traumatic brain injury) to psychological repercussions. Physical training focused on muscle strength, balance, and gait has consistently been shown to prevent falls. However, there are significant challenges in its implementation, such as the need for trained personnel and long intervention times, which are associated with high costs. Therefore, developing strategies to improve the efficiency of physical training programs in older adults is mandatory. The reduced response to physical training in older adults compared to younger individuals is a well-documented phenomenon, reflecting physiological changes associated with aging. Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme for cells, mediating energy metabolism and participating in crucial processes such as DNA repair, mitochondrial function, and cell death. As we age, NAD+ levels decrease in various tissues (including the brain and muscle), contributing to the development of aging phenotypes and associated pathologies. Preclinical evidence suggests that increasing NAD+ levels reduces the appearance of aging phenotypes. During physical activity, cellular metabolic pathways that increase the demand for NAD+ to support energy production in mitochondria are activated. This increase in demand is associated with the upregulation of key enzymes involved in NAD+ degradation promoted by exercise. Considering the decrease in cellular levels of this coenzyme associated with aging, it can be hypothesized that NAD+ deficiency may play a significant role in the reduced response of older adults to training programs. Nicotinamide, a water-soluble form of vitamin B3 currently considered a nutritional supplement, is a fundamental precursor for NAD+ synthesis, capable of raising cellular levels of it. It has already been used in clinical practice in the treatment of certain endocrinological and dermatological conditions. This study aims to determine through a randomized clinical trial whether nicotinamide supplementation improves physical performance in older adults at risk of falls undergoing a physical training program.
Chronic non-specific neck pain (CNNP) poses a significant challenge in healthcare, sparking interest in conservative and innovative therapeutic options such as high-intensity laser therapy (HILT). While evidence of its efficacy in this specific context remains limited, there is a robust foundation supporting the use of HILT in managing chronic neck pain, demonstrating effectiveness in pain reduction and functional improvement. Therefore, the aim of this study is to evaluate the clinical response to HILT treatment in patients with CNNP, investigating its potential therapeutic benefits and adverse effects. The findings of this study will provide valuable insights into the clinical experience with HILT in this population, serving as a pivotal starting point for future research in this field. In a clinical trial, patients with CNNP will undergo a treatment regimen consisting of two weekly sessions of HILT and stretching exercises over four weeks. The study aims to assess primary outcomes such as resting pain intensity (RPI), movement pain intensity (MPI), and pain pressure threshold (PPT), measured using the numerical pain rating scale and algometry. Secondary outcomes will include cervical range of motion (CROM) and neck disability, assessed through inclinometry and the Neck Disability Index (NDI). Evaluations will occur post-treatment, with a follow-up assessment scheduled one month later.
This is a randomised, double-blind, parallel group, placebo-controlled Phase IIa study designed to evaluate the efficacy and safety of AZD7798 in participants with moderate to severe Crohn's disease.
Breast cancer (BC) is the most common neoplasia. Frequent for women and half of the new cases occur in people over 65 years of age. The treatment of BC generates adverse effects that deteriorate the physical functionality, muscle strength and quality of life of the survivors. This is more noticeable in elderly BC survivors. Physical exercise improves some adverse effects of BC, but few studies have focused on physical functionality, especially in older people. The elderly population reports the lowest adherence and lower level of physical activity. It is relevant to explore innovative and specific proposals for physical exercise for elderly survivors of BC. One solution may be virtual reality game-based exercise, which has been shown in healthy older people to significantly improve physical functionality and adherence compared to traditional physical exercise. The objective of our study is to estimate the feasibility and effect of a virtual reality-based exercise program on the functionality, muscle strength, and quality of life of older BC survivors, compared to a group undergoing traditional physical exercise.
The purpose of this study is to evaluate the safety and effectiveness of the Extended Magnetic Grasper Device in patients undergoing bariatric and/or hiatal hernia procedures, as a liver retractor grasping the liver and/or the tissue surrounding the crus of the diaphragm.
The study aim to evaluate safety of exosomes (sEVs) from allogeneic mesenchymal stromal cells delivered by an intra-articular injection in the knee of patients with mild to moderate symptomatic osteoarthritis. The sEVs will be produced in a GMP-facility. The investigators expect to enroll 12 patients in this phase 1 trial open label dose-escalation pilot and the follow-up will be up to 12 months.
To analyze the possible benefit of damage control surgery by performing bowel resection, open abdomen, and delayed anastomosis in the treatment of Hinchey III or IV diverticulitis.
This randomized controlled trial will compare the effects of neuroplastic and functional changes of Hand-Arm Bimanual Intensive Therapy Including Lower Extremities (HABIT-ILE) when presented in two periods (2HG; n=24) versus a single period (1HG; n=24) in people with bilateral CP. The 1HG will receive 65 hours of HABIT-ILE over one intervention period; the 2HG will receive 130 hours over two intervention periods, within 6 months apart. Children will be assessed at 6 time points: baseline, three weeks after the start, at 3, 6, 7 and 9 months after the start of the study.
