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 SLEEP-BP-CKD Study has been designed to specifically test the following primary hypotheses: (i) Specific ABPM-derived parameters, in particular the asleep SBP mean and/or the sleep-time relative SBP decline, are significant prognostic markers of deterioration of kidney function and progression towards ESKD, as well as of the risk of all-cause mortality and major CVD events, in high-risk patients with stage G3b-G4 CKD. (ii) Changes during follow-up in specific ABPM-derived parameters, in particular the increase of the asleep SBP mean and/or decrease of the sleep-time relative SBP decline towards the non-dipper/riser 24h SBP pattern, are significant prognostic markers of deterioration of kidney function and progression towards ESKD, as well as of the risk of all-cause mortality and major CVD events, in high-risk patients with stage G3b-G4 CKD. A novelty of the SLEEP-BP-CKD Study is the incorporation of clinical-grade wearable digital technology to monitor both wake-time and sleep-time BP at home in a subgroup (up to 200) of the total sample; this procedure will provide added useful information to test the following additional hypotheses: (iii) The HBPM self-assessment procedure to obtain BP measurements both during wake-time and sleep-time spans provides reliable data to be used either individually or jointly with periodic ABPM as added potential prognostic marker of deterioration of kidney function and progression towards ESKD, as well as of the risk of all-cause mortality and major CVD events, in high-risk patients with stage G3b-G4 CKD. (iv) The sleep-time BP measurements obtained by HBPM self-assessment and their changes during follow-up are better correlated, compared with wake-time OBPM or wake-time HBPM, to eGFR and albuminuria (measured by the albumin/creatinine ratio) and their changes during follow-up, respectively. (v) The HBPM self-assessment procedure to obtain BP measurements both during wake-time and sleep-time spans increases patient adherence/compliance to prescribed treatment from baseline. The scheduled periodic patient BP assessments during follow-up with OBPM, HBPM, 48h ABPM, along with laboratory urine and blood test data will further allow evaluating and comparing the changes from baseline in all these clinically relevant variables as potential markers for risk of progression towards ESKD, all-cause mortality, and/or CVD morbidity.
In response to the COVID-19 crisis, ISACS-TC has promoted a new registry of the existing and further centers of the same geographic areas to support clinical research to prevent, and treat the COVID-19 illness. These efforts are made possible by the generous contributions of clinical research volunteers in some of the countries participating to the prior acute coronary syndrome network.
Transfusion management improvement programs, generally known as patient blood management (PBM) programs, are based on a set of perioperative measures aimed at improving clinical outcomes by avoiding unnecessary exposure to blood components. In a recent series of liver transplants (LT) performed in Spanish centers belonging to the Spanish Liver Transplant Society, despite optimal hemostasis management and preservation of the vena cava, around 20% of patients required massive transfusion (considered as the administration of 6 or more red blood cell concentrates intraoperatively). In addition, 63% of the patients were transfused with at least one packed red cells during the operation. By correcting the iron deficiency in patients who meet the criteria of the anemia study (transferrin saturation less than 20%), we could improve the hemoglobin level, which would allow a wider margin for the transfusion of red cell concentrates.
Dry Eye Disease (DED) is a multifactorial pathology characterized by inflammation of the lacrimal functional unit that develops in ocular surface pathology, severely affecting patients quality of life. The core of the treatment relies at present in antinflammatory topical therapies, which are still scarce. The investigators hypothesize that osteopathy-based techniques may help these patients by influencing the central involvement regarding parasympathetic innervation of tear and saliva-secreting glands. The aim of this osteopathic treatment protocol is to release the involved structures in the tear-secreting system innervation, such as the sphenopalatine ganglion. In addition, this ganglion innervates the minor salivary glands, therefore it is intended to help patients suffering from xerostomia. The hypothesis then is that a systemic protocol treatment can help balance both parts of the vegetative nervous system (sympathetic and parasympathetic) with the objective of increasing the secretion of tear and saliva in patients with ocular and oral dryness (DED and xerostomia, respectively), thus improving their clinical situation. This osteopathic protocol does not have the potential to cause adverse effects. The main objective is to analyze the efficacy of this protocol application in terms of improving symptoms and signs of ocular and oral dryness, tear film quality and inflammation molecule levels in tears and saliva.
This is a multi-part, randomized, double-blind, placebo-controlled Phase 2 clinical study comparing the safety and efficacy of bezuclastinib (CGT9486) plus best supportive care (BSC) with placebo plus BSC in patients with nonadvanced systemic mastocytosis (NonAdvSM), including indolent systemic mastocytosis and smoldering systemic mastocytosis, whose symptoms are not adequately controlled by BSC. This study will be conducted in three parts. Patients in Parts 1a, 1b and 2 will receive bezuclastinib or placebo, and may roll over onto Part 3 to receive treatment with bezuclastinib.
Bipolar Disorder (BD) is a chronic and severe mental illness characterized by the emergence of alternating mood episodes which range from extreme depression to manic states. Beyond affective episodes, there is consensus considering that cognitive and functional impairment are also core features in a substantial proportion of patients suffering from this mental condition, being both of them responsible of a negative impact on perceived quality of life (QoL). Despite, the association between cognitive performance, clinical and functioning outcomes in patients with BD has been largely explored among adult and middle-aged patients, there is a dearth of research about aging process among older adults with bipolar disoder (OABD) as well as in the design of tailored intervention targeting older individuals. Due to the longer life expectancy and subsequent aging of the world's population, is becoming increasingly common that people presenting with chronic health condition, including BD, survives longer. Currently, it has been estimated roughly the 25% of whole BD population is over 60 years old and it is expected that this percentage will increase up to 50% by 2030. Consequently, there is an urgent need not only to explore specific implication in clinical and neurocognitive course and to investigate symptom development throughout this vital stage elder-life phase, but also to design specific interventions aimed to cope with special needs in this specific population.
Endocardial ganglion plexus ablation (cardioneuroablation) represents a promising therapeutic technique for the treatment of vasovagal syncope (VV), functional atrioventricular block (AVB) and sinus node dysfunction (SND) with a component of vagal hypertonia. Nevertheless, there is currently a paucity of literature about the results according to the type of presentation (VV, AVB or SND). The investigators aim to assess the safety and efficacy of cardioneuroablation for the treatment of symptomatic SND.
A Randomized, Double-blind, Multi-center, Phase III Clinical Study of Ivonescimab (SMT112 or AK112) or Placebo Plus Pemetrexed and Carboplatin in Patients With EGFR-mutant Locally Advanced or Metastatic Non-squamous Non-small Cell Lung Cancer Who Have Progressed on or Following Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI) Treatment (HARMONi)
Epithelial ovarian cancer (EOC) diagnosed in the initial stage (stage I-II) require complete staging surgery to histologically assess the possible existence of peritoneal or lymph node disease. Systematic pelvic and paraaortic lymphadenectomy in stage I-II EOC is essential since confirming the presence of lymph node metastases means re-staging the disease as stage III. This change of stage has important prognostic and therapeutic implications. However, the lymph node involvement rate is around 10-30% (average of 15%). Systematic pelvic and para-aortic lymphadenectomy carries a risk of intraoperative complications, as well as longer operative time, postoperative complications and longer hospital stay. Moreover, by now there is no evidence suggesting a possible therapeutic value. The sentinel lymph node (SLN) detects the first level of lymph node drainage. The absence of metastases in the SLN predicts the absence of tumor infiltration of the rest of lymph nodes of the same anatomical region and allows to safely avoid lymphadenectomy and its associated morbidity. In addition, the exhaustive evaluation of the SLN by ultrastaging and immunohistochemical study allows to increase the detection of microscopic disease. Sentinel lymph node (SLN) biopsy, implemented in clinical practice in other gynecological tumors (breast, vulva, cervix or endometrium), has been studied very little in the initial ovarian epithelial cancer. Unlike other gynecological tumors, there are multiple anatomical and technical aspects that largely explain this lack of information. The double ovarian vascularization that accompanies lymphatic drainage explains this higher complexity. Therefore, at the present time, the detection of SLN in the initial EOC remains an experimental area without applicability in clinical practice. There are multiple doubts and issues to be resolved regarding the different tracers, the site and time injection and the actual accuracy of the SLN versus the lymphadenectomy.
