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.
Clinical, prospective, comparative, controlled, single-blind study, on the signs and symptoms of dry eye before and after 3 days of playing video games with the use of artificial tears (Hyabak) versus no intervention.
Type 2 diabetes (T2D) is a progressive chronic condition associated with a high morbi-mortality that has a considerable impact on healthcare resources. Glucagon-like peptide-1 receptor agonists (GLP-1RA) are incretin mimetics that have been shown to improve glycemic control with a low associated risk of hypoglycemia. Additionally, previous studies have linked the use of GLP-1RA with a reduction in the risk of cardiovascular events and kidney disease progression. Despite these positive results, GLP1-RA´s prescription, following the failure of treatment with metformin monotherapy or dual therapy, remains low in Spain compared to other countries in our milieu. Furthermore, the use of this therapeutic class is not homogeneous across the different autonomous communities in Spain, and, no objective justification for these differences seems to exist. Consequently, there is a need to understand which are the benefits associated with the use of GLP-1RA, versus intensification with other oral agents, in real-life conditions. In this study, the impact of the use of GLP-1RA on clinical outcomes such as all-cause mortality, cardiovascular and renal outcomes as well as severe hypoglycemia will be evaluated based on the analysis of longitudinal databases that collect the variables of interest generated in a real-life scenario. In addition, both persistence and adherence to treatment in patients treated with GLP-1RA and its impact on the clinical outcomes of interest will be studied. Finally, therapeutic inertia will be analyzed. All these data will contribute to generating cost-effective strategies aimed at improving health outcomes among T2D patients in our setting, reinforcing persistence and adherence to the prescribed treatment, and reducing therapeutic inertia in this group of patients. Since the use of GLP-1RA versus intensification with other oral agents has been associated with better glycemic control, and, when compared to intensification with basal insulin, with a lower incidence of severe hypoglycemia, we hypothesized that T2D adults treated with GLP-1RA would present a lower incidence of cardiovascular and renal outcomes and fewer hospitalizations due to severe hypoglycemia events as well as a decreased all-cause mortality. On the other hand, patients on GLP-1RA who would present greater persistence and adherence to treatment should experience fewer cardiovascular and renal outcomes and lower mortality compared to those with less persistence and adherence. Finally, it is possible that the type of GLP-1RA and the mode of administration, weekly versus daily, may influence adherence, persistence and therapeutic inertia in this group of patients.
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common supraventricular tachycardia inducible during an electrophysiological study. Although ablative therapy proved to be the treatment of choice, little is known about the components of the tachycardia circuit. The aim of this study is to detect the presence and patterns of specific electrograms representing slow pathway (SP) potentials and to explore Koch's triangle pattern activation during sinus rhythm and/or atrial extraestimulus with a high-density mapping catheter in an attempt to clarify a fast and safety catheter ablation strategy. We hypothesized that, in patients with dual atrioventricular nodal physiology, during sinus rhythm (SR), high-density mapping (HDM) catheters could identify the SP signals, making possible to delineate small areas of slow conduction associated to abnormal electrograms on Koch's triangle. On a second step, radiofrequency (RF) applications safety guided by the HDM obtained with this method, should interrupt the circuit far from the His region. Finally, SP signals should disappear after the RF procedure when performing a new 3D HDM. A control group of patients without AVN dual physiology should show absence of fragmented/slow conduction zones.
The oral bioavailability of Oleanolic acid (OA) when formulated as functional olive oil, and its mechanisms of systemic transport, will be approached by mean of randomized and controlled trial with 20 healthy volunteers. Ten individuals randomly selected will receive 55 mL of the functional OA-enriched olive oil (equivalent dose 30 mg OA) as part of an experimental breakfast. The other ten participants will receive within this experimental meal the same amount of the control olive oil. Immediately before and after eating the respective breakfasts, aliquots of cubital blood will be drawn every hour, over a postprandial period of 7 hours. Since in this trial design, each participant is his/her own control, a four-week washout period is established, after which a new series of tests that cross the type of olive oil consumed will be carried out. From the aliquots of cubital blood, sera will be obtained by centrifugation. The extraction and quantification of serum OA will be realized by gas chromatography (GC) using flame ionization (FID) and mass spectrometry (MS) detectors. In the pharmacokinetic analysis of data, a mono-compartmental model will be assumed. It will be determined: 1) absorption parameters such as the maximum concentration achieved and the timing for it, the constant of absorption and the area under the curve; 2) distribution parameters such as the constant and volume of distribution; 3) metabolism parameters, such as the OA fraction associated with albumin; and 4) elimination parameters such as the elimination constant, the half-life and the clearance. To demonstrate the presence of OA in postprandial TRL, chylomicron and VLDL fractions will be prepared by plasma ultrafiltration in normal saline, and hydrolysed with pancreatic enzyme. The possible presence of OA among the TRL-derived lipids will be evaluated. The content of apo B48 and B100, as markers of the presence of chylomicrons and VLDL, respectively, will be determined by ELISA. Other parameters related to glycemic control, such as serum insulin, C-peptide and GLP-1 will be analyzed by ELISA.
Aim: The aims of this study are: (1) to present the development, content validation and implementation study of the Relationship Competences Guiding Tool (RCGT); (2) to show some examples of how each of the items of the guide may be reflected on clinical narratives written by nurses, and justify its corresponding scores after the evaluation; (3) to present how the language and content of the narratives are interpreted with this guide and to describe an exemplar; (4) to present barriers and facilitators of its application. Background: From a person-centred care approach, the fostering of authentic relationships with patients is key for therapeutic benefits. Therefore, it is essential to help nurses to establish meaningful relationships with patients and help them to achieve these abilities. In this line, clinical narratives can be used as a way to promote reflective practice and professional competences development between nurses. A guide to evaluate the knowledge, skills, attitudes and values necessary for developing authentic encounters with patients reflected by nurses on clinical narratives was developed and implemented. Design: Design and evaluation of the RCGT, and evaluation of its implementation Methods: This study was conducted in three major steps. Step one entailed the conceptualization. Step two included the generation of items and content validation. Then, in step three, the tool was used to independently evaluate 25 narratives by two researchers, in order to identify and exemplify the attributes of the nurse patient relationship defined on the guide and identify barriers and facilitators. One of the narratives was linguistically analysed in the light of the guide, in order to provide a comprehensive view of the interpretative strategies deployed by evaluators. Results: The RCGT helped to identify nursing professional competences reflected in clinical narratives. The tool guided in the process of assigning scores to the corresponding items. The use of the tool helped to identify some barriers and facilitators before and during the narrative evaluation process. Conclusions: A clear, relevant, conceptually and linguistically adequate guide for assessing clinical narratives was obtained. The RCGT can be applied to accurately interpret how nurses reflect professional competences in a clinical narrative as a preliminary step to design a measurement tool.
Malnutrition is common in patients with heart failure (HF) and is associated with a worse prognosis. However, there is little information on the impact of nutritional intervention in malnourished patients with heart failure. Therefore, the aim of our study is to evaluate whether a specific nutritional intervention has an impact on mortality and hospitalizations, quality of life, nutritional status, and functional capacity in patient with heart failure and malnutrition.
Pilot, single-blind, randomized and controlled study to evaluate the changes produced in the visual function of patients with glaucoma after oral administration for 3 months of citicoline and docosahexaenoic Acid (DHA) vs citicoline and docosahexaenoic Acid (DHA) vs vitamin C.
The home confinement caused by the COVID-19 pandemic has aroused the need to use telematic communication systems to provide remote treatments. More and more research is being done on preoperative respiratory physiotherapy in patients undergoing thoracic surgery with lung cancer. It is a treatment that has great relevance in the prevention of postoperative complications and in the quality of life of the patient. Therefore, this study is proposed to highlight the applicability of a telematic system of preoperative physiotherapy treatment with the FISSIOS application at the Hospital de la Santa Creu i Sant Pau (HSCSP).
Randomized, single-center, parallel, team-stratified, stratified experimental study to evaluate the efficacy of a high sports supplement in improving high-intensity intermittent exercise performance in professional female soccer players.
The extracorporeal shock wave lithotripsy (ESWL) is the treatment of choice for most stones in any of their locations. It is about breaking the stone without surgically intervening on the patient and getting him to expel the fragments himself. It is thought that additional treatments to the ESWL could improve the success rate of ESWL for less favorable stones. The components of our authorized food supplement have shown an inhibitory effect in vitro on the growth of calcium oxalate monohydrate crystals, even in hightly supersaturared solutions. Also these components show an inhibitory effect on the growth of calcium phosphate crystals. To sum up, it reduces the formation, inhibits the growth and promotes the dissolution of calcium oxalate and calcium phosphate kidney stones. This is the reason why this experimental study aims to modify the size limit of the stones in the ESWL with adjuvant food supplement.
