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.
Aortic stenosis (AE) is a disease that has been increasing steadily in recent years in most countries, including Spain.Risk factors for the development of AE include age, hypercholesterolemia, diabetes mellitus and arterial hypertension, the classic risk factors for the development of atherosclerosis. However, lipid-lowering therapy with statins and ezetimibe has not been shown to reduce the risk of long-term progression of AE by unknown mechanisms. All this suggests that subjects with HFhe have a high risk of developing AD, which has not been shown by the high coronary mortality in this population that precedes aortic calcification
Several studies indicate that Nitric Oxide (NO) plays an important role in the physiology of the reproductive system in mammals. It has been shown that NO affects sperm motility, it regulates the tyrosine phosphorylation of different sperm proteins, it enhances the sperm binding ability to the zona pellucida and it modulates the acrosome reaction. The enzyme responsible for NO synthesis, the Nitric Oxide Synthase (NOS), has also been identified in the oocytes, cumulus and corona cells, as well as in the oviduct. For these reasons, the NOS presence at the fertilization site could be a key element to determine the success of this process. Therefore, carrying out in vitro studies to better understand NO's role in the fertilization process, especially in human sperm capacitation, could improve the outcome of the Assisted Reproductive Techniques (ARTs) due to an improvement both in the diagnosis of infertility and in the prognosis of treatment success. This study is carried out in collaboration with the Animal Physiology Department from the Veterinary Faculty (University of Murcia, Spain) and it is funded by the European Commission under the Horizon 2020 Programme.
A non-randomised, prospective study to assess the effects of beta-blockers on substance P levels and the swallowing function. The study is going to be carry out in the Gastrointestinal Physiology Laboratory of the Hospital de Mataró (Spain). All participants will be actively recruited from a Linked hospital and primary care database. We include two groups: the first group (group 1) are participants taking beta-blockers and the second group (group 2) are participants not-taking beta-blockers.
There is a growing number of evidence of how mindfulness training enhances psychological and physical well-being and coping strategies in patients with oncological illnesses. However, there are very few studies analyzing the efficacy of Compassion-Based Interventions on breast cancer survivors. The goal of this study is to analyze enrollment, participant satisfaction and adherence to program and differences in psychological well-being, health related quality of life, fear of illness recurrence, compassion and self-compassion variables after a Compassion-Based Intervention in a Spanish breast cancer survivor sample. This study is a randomized clinical trial of a secularized intervention called Cognitively-Based Compassion Training (CBCT). Subjects (n = 58) were randomly assigned to CBCT (n = 28) or a treatment as usual control group (TAU) (n = 28). Participants in the CBCT intervention condition were asked to meet weekly for a two (2) hour long session during two months. Pre-post-intervention and six month follow-up measures took place to evaluate: psychological well-being (somatic, depressive, and anxious symptomatology), health related quality of life (physical, social, emotional, and functional); psychological stress, coping strategies and triggering cognitions linked to cancer recurrence fear, self-compassion, compassion and mindfulness and awareness in both intervention and wait list groups. CBCT is a promising and potentially useful intervention to enhance physical and emotional well-being in breast cancer survivors. Nevertheless, future randomized trials are needed and a process of cultural adaptation required.
The knowledge and completion of advanced directives (ADs) by the population is generally low. Primary care could develop a very important role to inform and assist in the preparation of this document because of its accessibility. Objective: To evaluate the effectiveness of an oral brief information and a brochure administered in primary care to improve the proportion of ADs records. Design: Randomized clinical trial. Ambit: 7 offices from a urban health center which serves about 25,000 users older than 18 years. Material and methods It will be administered randomly triptych and oral brief information about the existence of advance directives for people over 18 to attend the appointment of their family doctor for any reason (intervention group). It will be given the possibility of more extensive information if they wish and collaboration will be offered for the advance directive according to patient preferences. The control group will not receive any information. Follow-up: 3 months. Variables will be: number of people interested in ADs, number of ADs made and demographic data (gender, age, education level, race, comorbidities, religion, testament) in both groups. Statistical analysis: multiple linear regression, Poisson and Cox as response analyzed, with the intervention/control group as the main variable adjusting for potential confounders. Bivariate comparison using Student t test or Mann-Whitney test (continuous variables) and chi-square or Fisher's exact test (categorical variables). 165 subjects were required in the control group and 165 in the intervention group. Conclusion: positive results of this study will bring out the brief information managed by family physicians increases the number of ADs thus facilitating the right to autonomy of the patient.
An Open Label Long-Term Study to Evaluate the Safety and Tolerability of Seladelpar in Subjects with Primary Biliary Cholangitis (PBC)
Lung cancer is the leading cause of death in men and the second in women with a 5 year survival in Europe of less than 15%. One of the methods most used for its treatment is pulmonary resection. The objective of this study is to analyze the clinical profile presented to patients after pulmonary resection.
The sleep apnea-hypopnea syndrome (SAHS) is a respiratory disorder characterized by frequent breathing cessations (apneas) or partial collapses (hypopneas) during sleep. SAHS is linked with the most important causes of death in adults from industrialized countries. Metabolic deregulation and cardiovascular and cerebrovascular diseases, such as atrial fibrillation, stroke, myocardial infarction and sudden cardiac death, could affect people having untreated SAHS. The gold standard method for SAHS diagnosis is in-hospital, technician-attended nocturnal polysomnography (PSG). Nevertheless, this methodology is labor-intensive, time-consuming, and relatively unavailable, especially in low-resource settings. These drawbacks have led to large waiting lists, which delay diagnosis and treatment and limits its effectiveness as single diagnostic method for SAHS. Blood oxygen saturation (SpO2) and pulse rate (PR) from nocturnal pulse oximetry (NPO) provide relevant and essential information to detect apneas. In addition, it is significantly less intrusive for patients and it can be easily recorded at patients' home. In the same way, automated signal processing and pattern recognition techniques have demonstrated to provide accurate tools able to detect and effectively use this information. Therefore, the investigators hypothesize that automated pattern recognition of at-home NPO recordings could provide reliable and efficient tools able to simplify the management of SAHS. The aim of this study is two-fold: 1) to prospectively assess the reliability and effectiveness of at-home NPO in the context of adult SAHS; 2) to design, optimize and extensively assess the diagnostic performance of automated NPO-based screening tools for SAHS. In order to achieve these goals, both PSG and NPO recordings are carried out ambulatory and simultaneously at patient's home. A portable polysomnograph (Embletta MPR, Natus) is used for standard PSG at home, whereas a portable wrist-worn pulse oximeter (WristOX2 3150, Nonin) is used for ambulatory NPO. In addition, conventional in-lab PSG and attended pulse oximetry are also performed simultaneously in the hospital facilities.
This epidemiological and observational study is aimed to assess cardiovascular risk (CVR) by investigating the prevalence of CVR factors (CVRF), target organ damage (TOD) and cardiovascular disease (CVD) in general population of the sanitary area of Toledo.
Approximately one million of Spaniards suffer from AlzhEimer´s Disease (AD) and this figure is expected to triple by 20150. The approved treatments modulate neurotransmission in general and are not specific or anatomically directed. In AD there is a dysfunction in cognitive and memory circuits. It has been shown that the deep brain stimulation (DBS) can specially modulate circuits in such a way that is modulable, and this approach is safe. The safety of this treatment and its biological effects are convincing enough to require further study of possible therapeutic effects of DBS in AD. The objectives are: To evaluate the security of DBS in AD (main objective). To study the influence of DBS in the progress of AD, to compare the effects of DBS on the brain metabolism neural connectivity and hubs using MEG, and to compare the effects between two different groups: fornix and Basal nucleus of Meynert (BNM). To achieve this, a prospective, double-blind comparison study between groups will be conducted, to evaluate the effects of DBS in 6 patients: group I (fornix) and group II ( BNM).
