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.
Conduction system pacing vs biventricular resynchronization therapy in systolic dysfunction and wide QRS: mortality, heart failure hospitalization or cardiac transplant (CONSYST-CRT II trial). Superiority trial that aims to study the composite endpoint consisting of all-cause mortality, cardiac transplant or heart failure hospitalization at 12-month follow-up.
This study aims to identify moderating variables that modify satisfaction with physical activity practice throughout the menstrual cycle (MC) in women with and without multiple sclerosis (MS) during High-Intensity Interval Training (HIIT) and strength training sessions, and to compare the acute effects of different types of physical activity sessions in women with and without MS. This study used a randomized crossover trial study and single-blind performed by women with MS, matched 1:1 based on age, lifestyle factors and country of residence, with women without MS to analyse the effect of physical activity practise on satisfaction, functionality, fatigue, and inflammatory profile throughout MC. Participants will visit the facilities approximately 10 times (4 preliminary familiarization visits and 6 visits to carry out a physical activity session in each phase of the MC) over a period of 3-4 months. Evaluation will comprise clinical, nutritional and psychological interviews including different variables such as satisfaction on physical activity; visual analogue scale of fatigue; abdominal obesity and anthropometric variables; dietary and nutritional monitoring; bioimpedance analysis; blood profile of hormone, inflammatory and cognitive function blood profile; neuromuscular strength, voluntary activation, and contractile properties; functional assessment (spasticity, knee angles, gait speed, walking endurance, balance, sit-to-stand test, timed up and go test); rating of perceived exertion; pain; muscle oxygen saturation; lactate; heart rate variability; quality of sleep and life; and body temperature. During the luteal phase, women with MS are expected to exhibit different acute responses to HIIT and strength training sessions compared to women without the disease.
This study is a multicentric, prospective, randomised, controlled, post-market clinical follow up (PMCF) study to investigate safety, visual outcomes and contrast sensitivity after bilateral implantation of either LuxSmart IOLs (study group) or LuxGood IOLs (control group).
The Catalan Cancer Plan (CCP) undertakes periodic audits of cancer treatment outcomes, including organ/space surgical site infections (O/S-SSI) rates, while the Catalan Healthcare-associated Infections Surveillance Programme (VINCat) carries out standardized prospective surveillance of surgical site infections (SSIs) in colorectal surgery. This cohort study aimed to assess the concordance between these two monitoring systems for O/S-SSI following primary rectal cancer surgery.
The goals of this clinical trial are: 1. to study lactate kinetic between plasma and erythrocytes during an intervallic exercise and its subsequent recovery, considering the blood pH, the genotype for the T1470A polymorphism of the SLC16A1 gene (rs1049434), and the amount of MCT1 in erythrocytes membrane; 2. to analyze the levels of MCT1 in the erythrocytes membrane according to training status and genotype for the T1470A polymorphism of SLC16A1 (rs1049434). For this, the project will have two phases: - In phase I, trained participants will perform one maximal incremental test and one intervallic submaximal test with a final active recovery. - Phase II, levels of the MCT1 protein in the erythrocyte membrane will be quantified from trained and sedentary participants.
This is a Phase III, randomised, open-label, 3-arm, multicentre, international study assessing the efficacy and safety of Dato-DXd with or without durvalumab compared with investigator's choice chemotherapy in combination with pembrolizumab in participants with PD-L1 positive locally recurrent inoperable or metastatic TNBC.
In vitro maturation (IVM) is a technique for obtaining potentially fertilizable oocytes from immature oocytes. An oocyte must be mature both nuclearly and cytoplasmically in order to be competent in the reproductive process. Nuclear maturation involves an oocyte in metaphase II stage and is easily evaluated for its morphology. However, cytoplasmic maturation can only be evaluated by in vitro fertilization of that oocyte. A mature nuclear and cytoplasmic oocyte is the one capable of producing a viable embryo. This study aims to optimize the in vitro maturation (IVM) technique to achieve nuclear mature oocytes, i.e., to mature the oocytes up to the metaphase II stage. In addition, an artificial oocyte activation (AOA) will be carried out to check the cytoplasmic maturation of the oocytes, avoiding the generation of potentially viable embryos. This study corresponds to a second phase of the pilot study for the development of this technique in our IVF laboratory. We will use all we have learned in the first phase, as well as the experience acquired, to advance in the optimization of this protocol. The correct functioning of this IVM technique would mean a reduction in the costs of ovarian stimulation treatments, as lower doses and shorter stimulation times are required, which implies lower risks for women derived from the medication and less stress for them.
Certain pediatric liver transplant patients with immunosuppression levels in the therapeutic range and normal liver function tests present histological alterations (inflammation or fibrosis) in protocol biopsies. The objective of the study was to evaluate the histological findings of protocol biopsies performed at 2, 5, 10 and 15 years after liver transplantation in pediatric patients. A follow-up biopsy is also performed 1 and 3 years after liver rejection. To do that, a cohort study will be carried out by collecting clinical, analytical and histological data of patients undergoing post-liver transplant follow-up in pediatric hepatology and liver transplant outpatient clinics. According to the follow-up protocol for these patients, a liver biopsy is performed at 2, 5, 10 and 15 years after the transplant. In addition, ultrasound, elastography and general analysis with autoimmunity and HLA studies are carried out. The evaluation of the histological evolution of the liver graft and its relationship with clinical and analytical changes will favor the management of immunosuppressive treatment in pediatric patients with liver transplants.
Iron metabolism is related to several biochemical and functional factors that have a mayor impact in chronic obstructive pulmonary disease (COPD) such as hypoxia, hypercapnia, oxidative stress, chronic inflammation, cellular senescence, sarcopenia and ferroptosis. Ferroptosis is a specific form of cell death induced by excess intracellular free iron that generates lipid peroxidation of cell membranes, with subsequent cell death. The existence of excess ferroptosis in COPD due to tobacco smoke has been widely demonstrated in vitro both in respiratory tissue and in skeletal muscle. Iron and lipid metabolism disorders are an essential part of the pathogenesis of ferroptosis. These disorders have also been related to diseases that occur concomitantly with COPD, such as cardiovascular diseases. Recently, new genes related to iron metabolism that are involved in the development of ferroptosis have been identified. Proteins related with these genes have not been studied in vivo in the context of COPD and cardiovascular diseases. Some of them are purely intracellular in expression, but the expression of some of them can be measured in blood using methods available to any clinical laboratory. After an exhaustive study of the literature, we have selected a small group of circulating proteins expressed in DEGs (Differentially Expressed Genes) related to ferroptosis that overlap with the DEGs of COPD and the DEGs of atherosclerosis to evaluate the relationship between these molecules and clinical variables of COPD and their potential utility in identifying the risk of exacerbations, admissions, and cardiovascular events in COPD. This study could identify a trait in COPD useful for selecting patients at greater risk of exacerbation due to the relationship between ferroptosis and systemic inflammation and oxidative stress, cardiovascular risk and, in general, a worse prognosis of the disease. In addition, the identification of this trait can have important therapeutic implications.
The goal of this triple-blind randomized clinical trial is to learn about systemic adverse effects in first visit patients who attend an osteopathic medicine center in Barcelona. The main question it aims to answer are: • Check if there is a relationship between taking vitamin C and the reduction in the appearance of systemic adverse effects after osteopathic treatment (24-72 hours) First-visit patients, at the end of treatment, are asked to enter the study. If they accept, they are administered 1g. of vitamin C, or 1g. placebo or nothing. If there is a comparison group: Researchers will compare placebo group, control group and intervention group to see if there is a relationship between taking vitamin C and the appearance of systemic adverse effects].
