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.
The purpose of the study is to assess the safety and performance of the Omega™ LAA (Left Atrial Appendage) Occluder and Omega™ Delivery System in LAA (Left Atrial Appendage) closure for patients with non-valvular atrial fibrillation (NVAF) and high bleeding risk.
One of major challenges in orthodontics is to inhibit relapse and ensure stability of treatment outcomes. Retention is the phase of orthodontic treatment that attempts to keep teeth in the corrected position after correction with orthodontic braces. Without retention there is a tendency for the teeth to return to their initial position (1). Retention is usually necessary to overcome the elastic recoil of the periodontal supporting fibers and to allow remodeling of the alveolar bone. The bonded orthodontic lingual retainer constructed from composite and orthodontic wires provides an esthetic and efficient system for maintained retention and has been shown to be an effective means of retaining aligned anterior teeth in the post treatment position in the long term. This has been in popular use as a method of retention since the late 1970s (2). The traditional retainers, which are still in use, are multi-strand stainless steel retainers such as Penta-one® 0.0215 (Masel Orthodontics, Carlsbad, CA, USA). The main problem with multistrand stainless steel retainers is their high rate of failure. Clinical studies indicate that 5% to 37% of mandibular retainers fail during retention in some form, either bond failure or wire breakage (3-5). Reliance Orthodontic Products, Inc. (Itasca, IL, USA) recently introduced a bonded retainer system (Ortho-Flextech™ chain). This retainer's bonding is claimed to be quick and easy by reducing chairside time and eliminating laboratory costs (6). One other recently introduced retainer is Memotain™ (CA-Digital in Mettmann, Germany). Memotain is a CAD/CAM fabricated lingual retainer made of 0.014 X 0.014-inch rectangular nickel-titanium. The wire is highly flexible and custom cut to precisely adapt to the patient's lingual tooth anatomy. According to manufacturer, Memotain offers numerous perceived advantages to traditional multistranded lingual wires, including no need for wire measuring or bending, individually optimized placement, greater accuracy of fit, tighter interproximal adaptation, less tongue irritation, better durability, and resistance to microbial colonization (6). However, randomized clinical trials are necessary to determine whether these advantages are substantiated with scientific data. A recent review by the Cochrane group concluded that to date there is insufficient evidence to single out any particular retention strategy as the preferred method: it was recommended that future studies should include true randomization, reporting of dropouts, adequate sample size calculation, and a minimum follow-up period of 3 months (8). Thus, the aims of this multicenter, randomised controlled trial are: - To compare and evaluate the effectiveness and failure rate of Penta-one multistrand, Ortho-Flextech and Memotain retainers with each other - To compare the possible complications between the three retainers over time - To establish the cost-effectiveness of the three retainers - To evaluate the effectiveness of sandblasting in the retention of the wires
Coronary-related myocardial ischemia can result from obstructive epicardial stenosis or non-obstructive causes including coronary microcirculatory dysfunction and vasomotor disorders. This prospective study has been created in order to provide knowledge in the field of non-obstructive coronary artery disease.
Diacutaneous fibrolysis is a physiotherapeutic instrumental technique, used to treat musculoskeletal conditions causing pain and/or movement restriction. It is applied by means of metallic hooks, ending in a spatula with beveled edges, that seems to allow a better pressure distribution on the skin and a deeper and more precise application, compared to the manual approach. Recent studies indicate positive responses regrading pain intensity decrease in sports people suffering anterior knee pain, improving range of motion in subacromial impingement syndrome, improving sensory conductivity in symptomatic patients with carpal tunnel syndrome, decreased pain in patients with chronic epicondialgia or improveing function athletes with anterior knee pain. However, the specific action mechanism, have not been investigated in depth yet. There are no studies evaluating its effects on posterior muscular chain of lower extremity in athletes, where FD effects on neuromuscular response could be more evident due to the overload involved on this area. The aim of this study is to evaluate the immediate, and after 30 minutes, effects of a single diacutaneous fibrolysis session on flexibility, strength and neuromuscular activity on hamstring in athletes. A randomized controlled trial with blind evaluator. Randomization will be done between lower extremities of each subject (Random.org). Regardless of its own dominance, diacutaneous fibrolysis will be applied to de following muscles and intermuscular septums: gluteus maixmus, biceps femoris and semitendinosus to de lower experimental limb. The other extremity will not be treat (control limb). Sample recruitment. Athletes from UIC university community, who compete officially or institutionally, whether they are federated or recorded in a sport official register where the predominant activity focuses on the lower train (athletics, cycling, football, rugby...). Procedure. The anthropometric data will be collected at the beginning of the study. Each outcome assessment will be performed by a blinded evaluator at the baseline, immediately after the technique application and 30 minutes after.
Multicenter, randomized, double-blind, placebo-controlled, parallel group study to assess the efficacy and safety of metformin treatment at a dose of 1700 mg / day in adults with Huntington's disease. The study consists of a screening period (2 to 4 weeks), followed by a 52-week double-blind treatment period and a follow-up visit (one month after the end of treatment).
Vitamin D defiency during pregnancy is a major public health problem worldwide; In Spain, the average intake of vitamin D is lower than recommendations in an elevated percentage of the population, ranging from 50 to 95%, according to the Spanish Society of Community Nutrition (SENC). Recent research suggests that adverse pregnancy outcomes are associated to vitain D deficiency. Associated comorbidities are further complicated by the SARS-COV-2 Pandemic. Few studies have assessed the transmission of SARS-CoV-2 antibodies from mothers who have had the disease or have been vaccinated to their newborns, either at birth or during breastfeeding, or how vitamin D concentration influences the generation of such an immune response. The COVID-19 pandemic is a dynamic situation. Peer-reviewed studies in large study cohorts point to a clear relationship between prevalence and severity of COVID-19 and vitamin D deficiency.
The drug that will be investigated in the study is an antibody, GEN3014. Since this is the first study of GEN3014 in humans, the main purpose is to evaluate safety. Besides safety, the study will determine the recommended GEN3014 dose to be tested in a larger group of participants and assess preliminary clinical activity of GEN3014. GEN3014 will be studied in relapsed or refractory multiple myeloma (also known as RRMM) and other blood cancers. The study consists of 3 parts: 1. The Dose Escalation will test increasing doses of GEN3014 to find a safe dose level to be tested in the other two parts. 2. Expansion Part A will further test the GEN3014 dose determined from the Dose Escalation Part. 3. Expansion Part B will compare intravenous (IV) GEN3014 with the subcutaneous (SC) daratumumab in ex-US countries. Participants will receive either GEN3014 or daratumumab; none will be given placebo. The study duration will be different for the individual participants. Overall, the study may be ongoing up to 5 years after the last participant's first treatment.
Dietary intervention with UNICLA-A2 milk products containing beta casein A2 protein, and higher levels of omega-3 fatty acids and selenium may contribute to maintain the intestinal integrity, reduce inflammatory processes, normalize the immune system, protect against oxidative damage and equilibrate the gut microbiota in high-risk colorectal cancer patients who have undergone polypectomy
SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.
There is wide evidence regarding the weak points of end-stage Chronic kidney disease (CKD) patients in hemodialysis, and they include three intervention aspects: exercise, nutrition and psychological support. Evidence shows that exercise for patients in hemodialysis results in increased survival rate, functional capacity, strength and health-related quality of life. Additionally, different studies have shown the benefits of psychological interventions and the positive effect of educational programs on nutritional care for patients in hemodialysis. Despite the well-known benefits of exercise, this kind of programs are not being implemented in the routine clinical care of hemodialysis patients. Thus, the GoodRENal project aims to promote healthy lifestyles among dialysis patients in a holistic approach that combines exercise, nutrition and psychological wellbeing plus cognitive functioning addressing adult learners. The project will, in phase 1, explore barriers and facilitators of patients, carers and health professionals towards healthy lifestyle (physical activity, nutrition and psychological well being). In phase 2, the project will develop a health virtual platform including these three dimensions of cares. In summary, the project outputs will be: 1. A didactic content in a modular platform to create an educational program for integrated treatments in patients with dialysis 2. A guideline to promote healthy lifestyles among dialysis patients for health care providers 3. A guideline to promote e healthy lifestyles among dialysis patients for patients and formal - nonformal carers
