There are about 21071 clinical studies being (or have been) conducted in Spain. 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.
Assessment of SILKAM® suture material in mucosal closure in oral surgery (mucosal sutures). A prospective, monocentric, single arm observational study.
Study with the aim to see the effect on a space ground anaologue, Hyperbuoyancy Floatation (HBF) on cervical column.
The main objective of the study is to evaluate the efficacy of a combined training program of physical exercise and multisensory stimulation (Physiocognitive Integration) in people with mild/moderate cognitive impairment.
This clinical study evaluates the acute effect of glycerol ingestion on performance (power output), weight, urine specific gravity, biochemical (antioxidants and lactate) and metabolic (indirect calorimetry) markers in international athletes in hot conditions. The investigators hypothesized that acute glycerol ingestion can prevent performance loss (power generated at submaximal intensity) in hot conditions. To justify this hypothesis, the investigators will measure the aforementioned markers, which could establish a cause-effect relationship between acute glycerol intake and decreased performance loss in hot conditions.
Although the use of liver biopsy (LB) has decreased with the emerging non-invasive markers and techniques to evaluate liver fibrosis, histopathologic examination of liver tissue is necessary to confirm the type of liver injury. The aim of our study is to compare two methods for obtaining histological material from the liver: the percutaneous liver biopsy (PLB) and the Endoscopic ultrasound (EUS) guided liver biopsy (EUS-LB)
Randomized, controlled, double-blind, crossover clinical trial, depending on the product consumed, to analyze the efficacy on physical performance of a sports supplement consumed prior to and during competition or training.
Multicenter, prospective, non-randomized, post-market clinical follow-up (PMCF) study to confirm and support the clinical safety and performance of Xperience Pro to meet EU Medical Device regulation (MDR) requirements in all the CONSECUTIVE patients treated with Xperience Pro .
Multicenter, prospective, non-randomized, post-market clinical follow-up (PMCF) study to confirm and support the clinical safety and performance of NC Xperience to meet EU Medical Device regulation (MDR) requirements in all the CONSECUTIVE patients treated with NC Xperience .
For this retrospective study, the investigators will collect and analyze data of patients who presented with posterior artery occlusion and underwent mechanical thrombectomy (the type of endovascular stroke treatment) and intravenous thrombolysis (the type of non-endovascular stroke treatment). The electronic health records will be queried for the demographic, medical history, and outcomes data of all patients with posterior cerebral artery occlusion who underwent mechanical thrombectomy, intravenous thrombolysis (IVT), or medical management.
Cardiovascular disease is one of the most important causes of death and disability in the world. An autonomic imbalance is associated to cardiovascular risks and disorders. Electrical stimulation (ES) applied by surface electrodes is a non-invasive therapeutic approach with low side-effects. In the last years, some studies had investigated the effects of ES on the autonomic nervous system and cardiovascular system. However, different intensities, frequencies and electrode locations had been used, which makes difficult to clarify the optimal parameters. The aim of this study is to analyze the effects of ES on autonomic nervous modulation in healthy subjects comparing three different locations of application for ES. Participants will be aleatory assigned to one of three groups for a single-session of 20-minute transcutaneous ES: a) an auricular intermittent ES in an area that is believed to be connected to the vagal nerve (cymba conchae); b) an auricular sham intermittent ES, meaning a real ES but applied on an ear location not connected to the vagal nerve (scapha); and c) an upper back continuous ES (C7-T4), a placement that is thought to be connected to the stellate (sympathetic) ganglion. All the protocols will be stated at a non-painful intensity. After that, the hand grip exercise will be executed. The heart rate variability (HRV) and heart frequency (HR) will be measured in four main times: the baseline, in the final minutes of the ES, after the ES and after finishing the hand grip exercise. Blood pressure will be measured also at all the time points except during the ES due to the possibility of interferences. Adverse effects will be assessed after ES and 48 h later. The study will provide initial knowledge about how different electrical stimulation locations contribute to reduce sympathetic excitation and improve the sympathovagal balance.
