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.
Oxytocin (OT) is a hypothalamic peptide that enters the peripheral circulation via the posterior pituitary gland. OT plays a key role in regulating appetite, psychopathology, prosocial behavior and sexual function. Hypopituitarism is associated with increased obesity, increased psychopathology, sexual and prosocial dysfunction despite appropriate hormone replacement. A few studies suggest the existence of a possible OT deficient state in hypopituitarism. In animal models, melatonin has shown to increase OT release. This study is designed to evaluate oxytocin values after administration of melatonin in adults (healthy volunteers and patients with hypopituitarism). The investigators hypothesize that OT response will be blunted following melatonin in patients with hypopituitarism compared to healthy controls.
To compare the accuracy of the occlusal splints made by conventional impression and milled with the splint made by intraoral scanner and milled.
This three-arm cross-over randomized clinical trial (allocation ratio of 1:1:1) will aim to explore whether the application of intermittent vibratory forces modify RANKL and OPG concentrations in patients undergoing orthodontic treatment with clear aligners. The specific objective will be to compare gingival crevicular fluid concentrations of RANKL and OPG among groups according to the application or not of Acceledent® treatment at different time points and frequencies of aligner changes.
Multicentre, observational, retrospective study to analyze the differences in CMVi pattern and recurrences between two groups of allogeneic HSCT patients (haplo vs no haplo HSCT), with intervention both postransplant cyclophosphamide as GvHD prophylaxis, using a database with information from historical clinic data.
Single-blinded Randomized Controlled Trial conducted amongst a sample of healthy subjects divided into two different groups: the experimental treatment will consist in bilateral T12-L1 vertebral manipulation, whereas the control group will receive a sham intervention consisting solely in applying tension without properly manipulating. Body temperature, arterial tension and cardiac frequency will be measured before and after the intervention. Changes in the aforementioned variables will be measured.
To evaluate the positive effects of a home-based physical therapy intervention added to the usual physical therapy programs performed in children with neurological pathologies that induce sensorimotor impairments that affect their quality of life and the importance of the implications of their families in their treatment.
In Spain, obesity epidemic is one of the leading contributors of chronic disease and disability. Obesity is associated with higher morbidity and all-cause mortality risk especially when fat is stored in the abdominal area (i.e., increased visceral adipose tissue, VAT). Although current approaches such as energy restriction may be effective at reducing body fat and improving cardiometabolic health, their long-term adherences are limited. Time-restricted eating (TRE; e.g., 8 hours eating: 16 hours fasting on a daily basis) is a recently emerged intermittent fasting approach with promising cardiovascular benefits. Results from pioneering pilot studies in humans are promising and suggest that simply reducing the eating time window from ≥12 to ≤8-10 hours/day improves cardiometabolic health. However, currently, there is no consensus regarding whether the TRE eating window should be aligned to the early or middle to late part of the day. The EXTREME study will investigate the efficacy and feasibility of three different 8 hours TRE schedules (i.e., early, late and self-selected) over 12 weeks on VAT (main outcome) and cardiometabolic risk factors (secondary outcomes) in adults with overweight/obesity and abdominal obesity. The final goal of the EXTREME study is to demonstrate the health benefits of a novel and pragmatic intervention for the treatment of obesity and related cardiometabolic risk factors; an approach readily adaptable to real-world practice settings, easy for clinicians to deliver, and intuitive for patients to implement and maintain in their lives.
The main goal of DIANA is to investigate the potential discriminative power of multimodal biomarkers in COVID adverse outcomes. The study of the neuropathological underlying mechanisms in COVID from a translational approach at: (1) the behavioural-clinical level from cognitive, emotional and functional data; (2) the brain connectome level from structural and functional imaging data; and (3) biogenetic level from blood and stool data. Moreover, the investigators will develop machine learning based predictive models of cognitive, mental health, functionality, and brain connectivity evolution in post-COVID syndrome patients.
Phase IIb clinical trial to assess the Immunogenicity and Safety of a HIPRA's Candidate Booster vaccination (PHH-1V) in adults fully vaccinated with the adenovirus vaccine Vaxevria against COVID-19.
Background: Claustrophobia is the most common type of specific phobia, and in the context of performing an MRI, it leads to premature completion of the test or a sedation. According to some authors, 1,6% of the patients terminated the test prematurely due to claustrophobia, and, in addition, 3.8% underwent conscious sedation. These procedures increase the risk of complications, and the cost of care. The use of anxiolytics is an option to reduce anxiety, but these drugs carry the possibility of suffering adverse effects, and the fact that patients cannot drive home when the MRI is finished. For these reasons, it is especially relevant to determine which non-pharmacological interventions are most effective, and among them, the use of Immersive Entertainment Glasses is a low-interventionist option that can help to overcome fear of the test. Objective: To determine the effectiveness of Immersive Entertainment Glasses in the success of the performance of an MRI and in the reduction of anxiety levels, in patients who express having claustrophobia. Methodology: Design: Clinical trial with intervention and control group. Participants: patients who define themselves as claustrophobic and should have an MRI. The sample will be made up of 206 individuals, divided between an intervention group and a control group. expecting a 20% difference between the success of the test of the control and intervention group subjects. People who meet the inclusion criteria will be distributed into the control or intervention group. The intervention group will use the Immersive Entertainment Glasses to perform the MRI and the control group will have the support of the nurse through educational techniques. Expected results: the success rate in performing MRIs is expected to increase by 20%, thanks to the use of Immersive Entertainment Glasses. Expected duration: 12 months, or until obtaining the expected sample.
