NCT ID: NCT05143879 Completed - Athletes Clinical Trials

Long-Term Effect of Combined Citrulline and Nitrate-Rich Beetroot Extract Supplementation

Start date: May 1, 2018
Phase: N/A
Study type: Interventional

Citrulline (CIT) and nitrate-rich beetroot extract (BEET) are widely studied ergogenic aids. However, both supplements have been studied in sort-term and isolated. To the best of the authors' knowledge, the effects of combining both supplements on exercise-induced muscle damage (EIMD) and hormone status have not been investigated to date. Therefore, the main purpose of this study was to determine the effect and degree of potentiation of the long-term (9 weeks) mixture of 3 g/day of CIT plus 2.1 g/day of BEET (300 mg/day of NIT) supplementation on EIMD markers (urea, creatinine, AST, ALT, GGT, LDH and CK) and anabolic/catabolic hormone status (testosterone, cortisol and Testosterone cortisol ratio (T/C)) in male trained triathletes. This study was a double-blind, placebo-controlled trial where participants (n = 32) were randomized into 4 different groups: placebo group (PLG; n = 8), CIT group (CITG; 3 g/day of CIT; n = 8), BEET group (BEETG; 2.1 g/day of BEET (300 mg/day of NIT) ; n = 8) and CIT-NIT group (CIT-BEETG; 3 g/day of CIT plus 2.1 g/day of BEET (300 mg/day of NIT); n = 8). Blood samples were collected from all participants at baseline (T1) and after 9 weeks of supplementation (T2).

NCT ID: NCT05142553 Completed - COVID-19 Clinical Trials

Immunogenicity and Safety of a Booster Vaccination With a Recombinant Protein RBD Candidate Vaccine Against SARS-CoV-2 in Healthy Adults Volunteers Fully Vaccinated Followed by an Extension Period to Study a Fourth Dose Administration.

Start date: November 16, 2021
Phase: Phase 2
Study type: Interventional

This Phase IIb clinical study aims to compare the immunogenicity and safety of a booster dose of recombinant protein RBD fusion dimer vaccine as a heterologous booster (to subjects who have received the second dose of the Pfizer-BioNTech (Comirnaty) COVID-19 vaccine at least 182 days prior to the booster dose in this study) versus a homologous booster (subjects who received the second dose of the Comirnaty COVID-19 vaccine at least 182 days prior to the booster dose in this study) will receive a third dose of the Comirnaty vaccine). The extension part of the study aims to compare the immunogenicity and safety of a fourth dose of PHH-1V in subjects with a primovaccination with Pfizer-BioNTech (Comirnaty) COVID-19 vaccine plus either a booster dose of Comirnaty or PHH-1V versus those with three vaccinations of Comirnaty.

NCT ID: NCT05138471 Completed - Chronic Pain Clinical Trials

Addition of Transcranial Direct Current Stimulation and Transcutaneous Electrical Nerve Stimulation to an Education and Exercise Program in Subjects With Chronic Pain Due to Knee Osteoarthritis

Start date: November 17, 2021
Phase: N/A
Study type: Interventional

Knee osteoarthritis has a very high prevalence in the population over 50 years of age. Patients with osteoarthritis often suffer from chronic pain that becomes disabling, affecting both quality of life and mental and physical health. This pathology has also been linked to maladaptive plasticity in the brain, which can contribute to chronic pain. Therapies with neuromodulatory approaches, such as transcranial direct current stimulation (tDCS) and peripheral electrical stimulation (TENS), have been used therapeutically to counteract the maladaptive plasticity of the brain. Transcranial therapy and TENS can be a possible effective treatment in the rehabilitation services of the health system for the improvement of chronic pain and quality of life in different pathologies, such as chronic low back pain, fibromyalgia or knee and hip osteoarthritis.

NCT ID: NCT05138211 Completed - Clinical trials for Hemiparesis/Hemiplegia (One Sided Weakness/Paralysis)

Effects of Unilateral Robotic Assistance on Compensation Strategies and Muscular Activity During Hemiparetic Gait

Start date: October 18, 2021
Phase: N/A
Study type: Interventional

Hemiparetic gait is characterized by strong asymmetries that could severely affect the quality of life of stroke survivors. This asymmetry is due to motor deficits in the paretic leg and the resulting compensations in the non-paretic limb. In this study, the investigators aim to evaluate the effect of actively promoting gait symmetry in hemiparetic patients by assessing the motion and muscular activity of both paretic and non-paretic lower limbs. To this end, the investigators use a unilateral active Knee-Ankle-Foot Orthosis able to assist the paretic limb of hemiparetic patients during gait. The system is able to synchronize its action with the movement of the unassisted joints, promoting a natural and intuitive interaction. The device generates assistance to induce a healthy gait pattern on the paretic leg. The hypothesis is that a proper and natural interaction between the user and the exoskeleton would enable the patients to consider the robot action as a part of their own gait capability, improving their gait quality as consequence. Hemiparetic asymmetry is not only due to impairments in the affected limb, but also it is the consequence of biomechanical compensatory mechanisms that might arose in the non-paretic leg. The aim of this study is to assess the adaptation process of the subject to the exoskeleton assistance, and to evaluate the effects of such human-robot interaction in both paretic and non-paretic legs.

NCT ID: NCT05138185 Completed - Clinical trials for Hemiparesis/Hemiplegia (One Sided Weakness/Paralysis)

Proof-of-concept of a Robotic Knee Exoskeleton in Healthy Subjects and Hemiparetic Patients During Gait.

Start date: February 15, 2021
Phase: N/A
Study type: Interventional

Hemiparetic gait is characterized by strong asymmetries that could severely affect the quality of life of stroke survivors. This asymmetry is due to motor deficits in the paretic leg and the resulting compensations in the non-paretic limb. In this study, the investigators aim to evaluate the effect of actively promoting gait symmetry in hemiparetic patients by assessing the behavior of both paretic and non-paretic lower limbs. To this end, the investigators use a unilateral active Knee-Ankle-Foot Orthosis able to assist the paretic limb of hemiparetic patients during gait. The system is able to synchronize its action with the movement of the unassisted joints, promoting a natural and intuitive interaction. The device generate the assistance according to two differents strategies: (1) Replicating the movement of the helathy leg or (2) Inducing a healthy gait pattern on the paretic leg. The hypothesis is that a proper and natural interaction between the user and the exoskeleton would enable the patients to consider the robot action as a part of their own gait capability, improving their gait quality as consequence. Hemiparetic asymmetry is not only due to impairments in the affected limb, but also it is the consequence of biomechanical compensatory mechanisms that might arose in the non-paretic leg. We aim to assess the adaptation process of the subject to the exoskeleton assistance, and to evaluate the effects of such human-robot interaction in both paretic and non-paretic legs.

NCT ID: NCT05136287 Completed - Clinical trials for Diabetes Mellitus, Type 2

SEMAGLUTIDE VERSUS GLP-1 RECEPTOR AGONISTS. EFFECTIVENESS , SAFETY AND QUALITY OF LIFE IN PATIENTS WITH DIABETES MELLITUS 2. OBSERVATIONAL, PROSPECTIVE AND MULTICENTER STUDY. SEVERAL STUDY.

SEVERAL
Start date: February 1, 2022
Phase:
Study type: Observational

Introduction: GLP-1 receptor agonists (aGLP1) act increasing pancreatic insulin secretion in response to the glucose, they reduce glucagon secretion and reduce appetite by acting in the central level. Several aGLP1 were approved through different clinical trials where they showed efficacy in the glycemic control and reduction in cardiovascular events. They also showed weight loss in different clinical trials with patients with diabetes mellitus 2 (DM2) and also in specific clinical trial where the weight loss was the primary endpoint (STEP study). Objective: The objective is to evaluate and compare the weight loss in patients with DM2 treated with the different aGLP1 for the first time. Secondary endpoints are HbA1c reduction, changes in quality of life and physical activity and the safety of these drugs. Design: It is a postauthorization, multicenter, non-randomized and prospective study. Patients that will start treatment for the first time with aGLP1 will be recruited in 10 primary care centers in SERGAS Galician Hospitals for a period of 6 months and 44 weeks of follow-up. The primary endpoint will be to evaluate the wight loss with the different aGLP1 and the secondary endpoint will be HbA1c reduction, changes in the quality of life through the EuroQol-5D and changes physical activity through the SF-12 questionnaire, and also the safety of these drugs. The sample size will be of 360 patients. Statistical analysis: Previous studies showed efficacy in weight loss with semaglutide about (3,6-4,9 kg), while with other aGLP1 the weight loss was smaller , about (0,86-2,96 kg). Based in these data and with a 5% of significance level, a weight loss average in the aGLP1 group of 2,5 kg, average in semaglutide group of 4,2 kg, and combination deviation of 3,0kg, including 360 subjects we will have a statistical power above 90% to detect differences through T-test for independent samples. The justification of this simple size was performed with the statistical software SPSS 3.0 Conclusions: The SEVERAL study will try to provide information about weight loss efficacy, changes in quality of life, physical activity and safety of the aGLP1in patients with DM2 that start treatment with these drugs in the real life (Real-World Evidence)

NCT ID: NCT05134051 Completed - Clinical trials for Coronary Artery Disease

Microcirculatory Status After Intravascular Lithotripsy

MARVEL
Start date: October 6, 2020
Phase: N/A
Study type: Interventional

Due to differences in the mechanism of action, intravascular lithotripsy is likely to cause less distal embolization and microcirculatory dysfunction during plaque preparation. This may also translate into lower periprocedural myocardial infarction rates. Thus, this exploratory study aims to evaluate the microcirculatory function after the use of Shockwave® intravascular lithotripsy.
