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.
STUDY DESIGN Post market clinical follow-up; pilot study, prospective, controlled, randomized, split-mouth, blinded evaluation INTRODUCTION AND PURPOSE OF STUDY Continuous advancements in the field of glass ionomers have led to an increasing range of permanent indications, especially with regards to stress bearing Class II restorations. As a further development in the 3M glass ionomer category, Ketac Universal can be used for the abovementioned indication in a simplified procedure without the need for cavity conditioning or restoration coating. All products used in this study are CE marked thus can be used for routine clinical treatment. STUDY OBJECTIVES Objective of the study is to evaluate the clinical survival and quality parameters of Class II Ketac Universal restorations compared to intra-individual (split-mouth) Class II Ketac Molar Quick control restorations over time STUDY ENDPOINTS Primary Endpoint: 1. Evaluation of restoration survival over time based on the glass ionomer restoration criteria (simplified FDI criteria as proposed by Mathilde Peters et al.) Secondary Endpoints: 1. Evaluation of restoration quality based on the glass ionomer restoration criteria (simplified FDI criteria) 2. Evaluation of restoration wear based on comparison of digital impressions Safety Endpoint: 1. Evaluation of potential adverse events NULL HYPOTHESIS There is no statistically significant difference between both glass ionomers - regarding overall survival - regarding restoration quality parameters TEST GROUP Ketac Universal Aplicap Glass Ionomer Restorative (3M) CONTROL GROUP Ketac Molar Quick Aplicap Glass Ionomer Restorative (3M) - regarding restoration wear METHODS AND MATERIALS A total of 39 subjects were enrolled and treated. The study was originally planned with 80 patients. Due to slow recruitment, it was decided to decrease the number of patients. Treatment: After signing informed consent, test and control product were randomly assigned to the two study teeth (randomization letter). Restoration extension (e.g. mod) and reason for restoration placement (e.g. secondary caries, tooth fracture) were recorded in the CRF. Two teeth per subject were included. Each product was used strictly according to respective Instructions for Use without using the optional protective coating. Restorations were placed in combination with sectional matrix system (Palodent system) and according to best practice (especially with regards to moisture control). Finishing and polishing was done with the Sof-Lex system. Areas in close proximity to the pulp were covered with local application of a calcium hydroxide material in both study materials. Study teeth were excluded from study if pulp exposure had occurred or if only a repair restoration was required instead of a full Class II restoration. Evaluation periods: All subjects were evaluated by two independent evaluators according to Performance Criteria for Posterior Glass Ionomer Restorations (simplified FDI criteria) - at baseline at day of restoration placement or up to 1 month after restoration placement - after 6 months (± 1 months) - after 1 year (± 1 months) - after 2 years (± 1 months) In addition, photos (at least occlusal view) were taken of every study tooth prior to restoration placement and at every evaluation. In order to further assess the wear of both restorative materials, full arch digital impressions (both upper and lower jaw) were taken at baseline evaluation and at every following evaluation using 3M True Definition Scanner. STL files were digitally compared to those taken at baseline.
The purpose of the study was to analyze the effect of a synchronous-supervised online home-based group during a 6-month exercise program on physical fitness, body composition and adherence compared to an exercise recommendation group of patients undergoing breast cancer treatment without supervision.
The general objective of this randomized and longitudinal clinical study was to estimate the frequencies of ApoE variants both in the user population of the "Messengers of Peace" Residences and the "Associations of Relatives of Alzheimer's Patients" in Castile y Leon, since, due to its geographical location at the crossroads, it has received multiple genetic contributions from both northern Europe, the Mediterranean area and northern Africa. The main questions it aims to answer are: - What are the allelic frequencies of ApoE variants in the population of individuals with Alzheimer's disease in Castile and Leon? - Is there a correlation between the ApoE4 variant and the lipid profile in the blood of individuals with Alzheimer's disease in this region?
This study will evaluate mechanisms of resistance to anti-breast cancer therapies in tumor and blood samples from participants with human epidermal growth factor receptor (HER2) positive, hormone receptor (HR) positive or triple negative breast cancer.
The purpose of the study is to learn about the safety and tolerability of setanaxib in subjects with Alport syndrome, when added to their standard of care treatment. The study will assess how safe setanaxib is when compared to placebo. Study participants will be asked if they are experiencing any side effects at each study visit. In addition, tests in blood, urine and other examinations will be used to look at the safety of setanaxib. The study will also measure how well setanaxib works in comparison to a placebo, by measuring urine protein and certain markers in the blood and urine. The concentration of setanaxib in the blood will also be measured throughout the course of the study. Setanaxib is planned for use together with the current standard of care to hopefully provide additional therapeutic benefits by preserving kidney function. The study will be conducted at multiple research sites in the UK, Spain, and Czech Republic. Eligible participants will be randomly assigned to receive either setanaxib or placebo. Setanaxib dose level will depend on age and all participants will receive their standard of care in addition to setanaxib or placebo. The study consists of a Screening period of up to 4 weeks, a 24-week Treatment period and a 4- week Follow-up period.

the use of pressure wires is the standar of care to evaluate angiographically intermediate coronary lesions, however, limitations in the management of these type of lesions continue to be a challenge for the interventional cardiologist. The use of FFR has some limitations such as the use of adenosine due to its cost, adverse effects (e.g. transient atrioventricular block, angina, headache, etc.), time consuming and some relative contraindications for its use. In this sense, in recent years new rest indices (iFR, RFR, dPR) and hyperemic indices without adenosine (cFFR-NTG, Pd/Pa-NTG or cFFR) have been developed, demonstrating an improvement in terms of outcomes with its use, so they can also be used as a tool to guide us to plan our strategy. These new indices, particularly the cFFR-NTG, are simpler, at least as safe and have an excellent correlation with the FFR with adenosine in the assessment of intermediate coronary lesions. In recent years, functional assessment after intervention has also been increasingly implemented, which, like intracoronary imaging, can make us change our attitude and correlate with the prognosis. The lower implementation of this practice, especially in multivessel patients, may result from having to lose the position of the wire to check equalization, difficulty in crossing the wire, wear/breakage of the material after diagnosis (2-3 vessels), use more time and contrast, etc. These problems could be reduced, at least partially, with the use of the workhorse coronary guidewire pressure microcatheter to measure post-PCI functional assessment. Although the usefulness of post-PCI FFR has been demonstrated, there is no clearly established cut-off value (0.84-0.96) and it seems that in reality the values are a continuum of risk so that the higher the value, the better the prognosis . Furthermore, other simpler indices such as rest or hyperemic indices without adenosine have not been correlated with FFR in post-PCI. The purpose of this study is to evaluate the correlation between cFFR-NTG and other indices taking FFR as a reference in multivessel patients after undergoing intervention. Establish cut-off points and correlate it with adverse cardiovascular events (MACE) in a 1-year clinical follow-up.
Background. Rehabilitation and re-education using instrumental anorectal biofeedback are the main treatment of anorectal functional disorders producing incontinence and outlet obstructed defecation. These treatments imply intubation of patient and several sessions of treatment leading to high consumption of resources and costs. Hypothesis. A cognitive intervention based on original audiovisual programs developed specifically for the management of anorectal functional disorders is effective in correcting anorectal function disorders that cause fecal incontinence and evacuation disorders. Aim. To prove in two different protocols (fecal incontinence and dyssinergic defecation) the efficacy of specifically developed non-instrumental biofeedback techniques. Selection criteria. Patients with fecal incontinence and altered sphincter function and patients with outlet obstructed evacuation referred for biofeedback treatment. Intervention. In separate studies (incontinence and dyssynergic defecation) patients will be randomized into biofeedback and placebo groups. One session of either biofeedback or placebo intervention will be performed at the beginning of the intervention period and patients will be instructed to performed the assigned daily treatment at home. A visit for outcome assessment will be performed at 3 months in incontinence study and at 4 weeks in the dyssinergic defecation study. In addition, in the incontinence study a phone call will be performed after 6 months of the beginning of the study to evaluate treatment outcome. Biofeedback: patients will be taught to control anal and abdominal muscular activity by providing instructions using original video supports. Patients will be instructed to perform the same exercises daily at home in scheduled times. Placebo: a pill of placebo containing 0.3 g glucose will be administered every day at home.
Significant coronary disease of the left main coronary artery (LMCA) is found in 4%-5% of all coronary angiography procedures. Classically, it has been determined that a significant angiographic stenosis should reach at least 50% of the vessel diameter by visual estimation, which corresponds to 75% of the vessel area. However, angiography has a number of limitations inherent to the technique and location of stenosis, and other techniques are therefore available for evaluation. Intracoronary ultrasound (IVUS) deserves, together with the pressure guidewire, special consideration in determining the severity assessment (anatomical and functional) of lesions in this location. Using IVUS the most commonly used cut-off value is 6 mm2. in ambiguous lesions of the LMCA, a MLA >6 mm2 would indicate no revascularisation, a MLA <4.5-5 mm2 would indicate revascularisation, and MLA values between 4.5-5 and 6 mm2 would make it advisable to use FRF/iFR to decide. Optical coherence tomography (OCT) is another intracoronary imaging modality, with greater resolution and significant differences from IVUS. no MLA cut-off point with OCT has been demonstrated for the management of LMCA lesions. Due to the differences in imaging with both techniques, the thresholds established as cut-off points in IVUS cannot be extrapolated to OCT. The objective is to compare the minimal luminal area by IVUS and OCT of angiographically intermediate LCMA lesions and to assess the prognostic value of TCFA assessed by OCT.
There has been increasing interest in the use of patient-reported outcomes and experience measures (PROMs and PREMs) in clinical practice; yet few empirical studies have been conducted to evaluate the usefulness of such implementation. Objective: To evaluate the efficacy of the implementation of PROMs and PREMs in routine clinical care for improving health outcomes and satisfaction with health management. Design: Randomized control trial. Setting: In and outpatient departments of a public hospital in Spain. Participants: 1,440 adult patients managed for breast cancer, prostate cancer, chronic kidney disease, or bariatric surgery. Intervention: Patients will monthly complete, through an App from their smartphones, PROMs and PREMs (arm A, n=480), or only PREMs (arm B, n=480). Responses to PROMs will be transformed into a graphic summary, accessible for physicians and patients at the follow-up visits of the project (9 and 18 months after recruitment). Main outcome measures: Comparison of change among arms on the assessment variables - such as health-related quality of life (EQ-5D-5L), satisfaction with care, or patient-professionals communication. These constructs will be measured at recruitment and at follow up visits for all patients, regardless of their arm allocation (arm C would only be administered these questionnaires, without intervention, n=480). Expected results: Incorporating PROMs and PREMs in routine clinical care may improve patients' and health professionals' experiences on health care, as well as improve patients' health.
