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.
Scientific evidence regarding the influence of peri-implantitis on Schneider's membrane thickening is scarce and limited. Similarly, to date, there is no literature documenting the resolution of implant-associated maxillary sinusitis with peri-implantitis after treatment of peri-implantitis or removal of the implant. Therefore, the aim of this case-control study is to investigate the association between peri-implantitis and maxillary sinusitis. On the other hand, the changes that occur at the level of the maxillary sinus membrane after treatment of peri-implantitis or after implant explantation will be evaluated.
This is a randomized, controlled, open-label, prospective, multicentre clinical trial designed to assess the effects of a nutritional intervention on morbidity and mortality in patients with chronic heart failure. Through a simple 1:1 randomization process, patients will be assigned to the control group or the intervention group. Patients in the intervention group will undergo an individualised nutritional intervention program consisting of 3 pillars: diet optimization, specific recommendations ,and nutritional supplementation if nutritional targets are not achieved.
The purpose of this trial is to test different doses of the trial medicine (LEO 138559) at treating moderate to severe atopic dermatitis in adults. There will be 4 different doses, that will also be compared to a placebo (a dummy medicine that doesn't contain the active ingredient of LEO 138559). Each participant will be randomly assigned to one of the 4 doses of LEO 138559 or placebo. In all arms, injections of placebo may be used to mask the different doses. The trial will last up to 36 weeks, including a screening/washout period (up to 4 weeks), a treatment period (16 weeks), and a follow up period (16 weeks). The participants will visit the clinic 17 times. For the first 4 weeks of the treatment period, participants will visit the clinic every week. For the next 12 weeks of the treatment period, participants will visit the clinic every 2 weeks. For the 16 week follow up period, participants will visit the clinic every 4 weeks. The treatments will be given to the participants by staff at the clinic. They are given as an injection just under the skin. At each visit the doctor will check the participants atopic dermatitis and if they have had any side effects. Participants will also complete an electronic diary every day about their atopic dermatitis and quality of life.
The purpose of this study is to evaluate the clinical and endoscopic efficacy of guselkumab in pediatric participants with Crohn's Disease (CD) at the end of maintenance therapy (Week 52) among participants who were in clinical response to guselkumab at Week 12.
Knee osteoarthritis pain is one of the conditions commonly seen in general and specialized medicine. Knee arthroplasty is one of the most successful orthopedic surgeries for the treatment of this disease, significantly improving pain, disability, and the overall quality of life for patients who undergo it. However, there is a subgroup of individuals in whom the pain persists or even worsens. Radiofrequency has been introduced over 10 years ago as a neuroablative technique targeting the genicular nerves, which innervate the sensory terminals of the knee joint, for the treatment of chronic pain in that region before or after arthroplasty. However, the results have not been entirely consistent. Recent anatomical studies have demonstrated the presence of other sensory terminal branches of the femoral nerve, such as the infrapatellar branch of the saphenous nerve, medial vastus nerve, intermediate vastus nerve, and lateral vastus nerve, which could be useful targets for the treatment of post-knee arthroplasty pain. To date, no studies have been conducted to address post-knee arthroplasty pain through the application of thermal radiofrequency on the sensory branches of the knee from the femoral nerve (infrapatellar branch of the saphenous nerve, medial vastus nerve, intermediate vastus nerve, lateral vastus nerve). Therefore, The investigators aim to conduct a randomized double-blind clinical trial where The investigators will apply thermal radiofrequency on the sensory terminal branches of the femoral nerve in the knee, based on recent anatomical studies. The objective of the study is to determine if radiofrequency ablation of sensory nerves in the knee improves pain and disability in patients with post-knee arthroplasty chronic pain at the L'Alt Penedés-Garraf Health Consortium. Method: This is a randomized double-blind clinical trial with two arms. Two groups will be used, where one group will receive thermal radiofrequency of sensory nerves in the knee, and the other group will receive a placebo treatment. The hypothesis The investigators propose is that radiofrequency ablation will alleviate at least 50% of baseline pain and disability in at least 50% of the patients.
The primary objective of this study is to compare progression-free survival (PFS) in participants who receive sotorasib with platinum doublet chemotherapy versus participants who receive pembrolizumab with platinum doublet chemotherapy.
This study explores the impact of high-intensity exercise during fasting on energy metabolism and cognitive function in healthy adults. Changes in respiratory exchange ratio, blood substances, and cognitive performance will be measured after 24 and 34 hours of fasting with and without exercise in a randomized crossover design.
Stereotactic ablative Body Radiotherapy (SBRT) is an advanced radiation technique that allows for precise delivery of higher radiation doses in fewer treatment sessions, resulting in a shorter overall treatment duration. The available clinical evidence suggests that SBRT is highly effective in controlling localized prostate cancer (PCa) with acceptable side effects. On the other side, dose escalation is a commonly employed strategy in radiotherapy for prostate cancer. Recent studies have confirmed a dose-response relationship, demonstrating improved biochemical control with focal dose escalation to the identified dominant intraprostatic lesion (DIL) on multiparametric magnetic resonance imaging (mpMRI) of the prostate. The hypothesis of this study is that the combination prostate SBRT with focal dose intensification on the DIL with preservation of the prostatic urethra, would lead to a higher probability of local control without a significant increase in toxicity compared to standard clinical practice. This is a prospective single-arm phase II study designed to evaluate the effectiveness, safety and impact on quality of life of focal dose intensification using SBRT technology and extreme hypofractionated radiotherapy.
Primary biliary cholangitis (PBC) has been considered a rare disease and its management has been limited by the lack of therapeutic alternatives. PBC is a slowly progressing chronic liver disease characterized by an immune-mediated destruction of the intrahepatic bile ducts, which leads to cholestasis, portal inflammation, and ultimately liver cirrhosis and its associated complications (ascites, portal hypertension, etc), if not treated effectively. Thus, early diagnosis and close management of these patients with PBC is essential. First-line treatment with ursodeoxycholic acid (UDCA) improves liver biochemical parameters, delays histological progression, and increases liver transplant-free survival and overall survival. However, up to 40% of patients are non-responders to UDCA. Obeticholic acid (OCA) is recommended as second-line therapy in combination with UDCA for patients with an inadequate response to UDCA or as monotherapy in cases of UDCA intolerance. According to current clinical guidelines, the diagnosis of PBC includes a combination of elevated alkaline phosphatase (ALP) levels and the presence of anti-mitochondrial antibodies (AMA) (titer >1:40) and/or anti-nuclear antibodies (ANA) anti-gp210 or anti-sp100. AMA are highly sensitive and specific for PBC and are detected in nearly 95% of PBC patients. A liver biopsy is not necessary unless there is an elevation of ALP without the presence of specific AMA and/or anti-gp210 or anti-sp100 ANA or if coexistence with other liver diseases is suspected (autoimmune hepatitis, hepatic steatosis). The incidence of PBC has increased in recent years due to an increase in the diagnosis of cases in the initial phases, better awareness in the medical community and the development of more sensitive diagnostic tests. However, up to 31% of patients with PBC are lost without follow-up. The correct identification of patients with PBC is essential so that they can benefit from an adequate treatment and modify disease progression. To date, two studies (one Spanish and one Portuguese) showed that 27% and 45.5% of the patients lost with PBC presented advanced fibrosis, respectively. The objective of this study is to identify, through computerized data, patients with PBC who may be lost in the system and evaluate their clinical, analytical and demographic characteristics, and in a second phase, provide access to follow-up in specialized consultations.
