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 main objectives of this observational study are to compare the results of the sonographic parameter hand acceleration time (HAT) measured before and after creating an arteriovenous fistula (AVF) for hemodialysis and assess if it is associated with the incidence of hemodialysis access-induced distal ischemia (HAIDI). The secondary objectives are to study the incidence of HAIDI in patients intervened for the creation of an AVF in the last 6 months, study the AVF permeability at 6 months, and study the AVF-related complications at 6 months.
Percutaneous pulmonary valve revalvulation (PPVR) has emerged as an alternative to surgery for the treatment of congenital heart disease with right ejection pathway dysfunction. The Melody valve (Medtronic Inc., Minneapolis, Minnesota) was the first to be used, validated in 2006 by the European Commission and in 2010 by the Food and Drug Administration (FDA). Subsequently, the Sapien valve (Edwards SAPIEN pulmonic transcatheter heart valve, Edwards Lifesciences, Irvine, California) was subsequently approved for PPVR (Europe, 2010; FDA 2016). Infective endocarditis (IE) after PPVR is currently a major concern with an incidence after Melody PPVR estimated at 3%, much higher than the rate of prosthetic left-heart IE. The Sapien valve has been introduced more recently and some cases of IE have been published. Despite the attention this issue is receiving, there are few studies of sufficient size or statistical power to elucidate the risk factors for developing an IE after PPVR according to the type of valve implanted. Recently, a multicenter study was published by the American team of McElhinney et al (J Am Coll Cardiol 2021 ; 78 :575-589). Although it was a sizeable cohort (2476 patients), there was a large disparity in the ratio of patients who underwent revalvulation with either the Melody or Sapien valve, in favor of Melody patients (2038 Melody patients vs. 438 Sapien patients). In this study, the estimated risk of IE was higher for patients who received a Melody valve, according to univariable analysis but not anymore after multivariate analysis. To further answer this question, we develop an international retrospective multicenter registry whose main objective will be to characterize the incidence rate of infective endocarditis after percutaneous pulmonary revalvulation according to the type of valve implanted (Melody vs. Sapien) using a large population of patients with comparable characteristics (match-population).
Shoulder pain is one of the most common musculoskeletal conditions among athletes and sports enthusiasts who engage in overhead sports, and it can be highly disabling. Since the shoulder is one of the joints with the greatest range of motion in the human body, it is important to seek strategies that address trunk stability comprehensively to achieve full and effective joint mobility. The central role of the diaphragm in trunk stabilization has been the subject of research for over 50 years, although the exact mechanisms are still not fully understood. The objective of this study is to assess the effects of inspiratory muscle training on diaphragm thickness, inspiratory muscle strength, and shoulder pain in adult tennis players with non-specific shoulder pain. This is a single-blind, randomized controlled clinical trial. The intervention will last for 8 weeks. Patients with non-specific shoulder pain will be randomly assigned to one of two groups. The experimental group will undergo specific inspiratory muscle training, while the control group will receive no specific training intervention. Measurements of diaphragm thickness, inspiratory muscle strength, and shoulder pain will be taken before and after the intervention.

Participants will be randomly assigned to one of the three proposed arms, and the primary surgery will be performed.
HOLA is a prospective, randomized (1:1), hybrid type (implementation-effectiveness), phase IV, double arm, open label, multicentric study including virologically suppressed HIVinfected subjects who start or are currently under treatment with the LA antiretroviral combination CAB+RPV, to evaluate the out-of-hospital administration of this combination in terms of acceptability, appropriateness, feasibility and satisfaction.
Emotional disorders such as anxiety and depression are significantly underdiagnosed and undertreated, even though they are some of the most prevalent mental health conditions, especially among young individuals. Approximately 50% of mental health disorders manifest by the age of 14, and around 75% appear by the age of 24, underscoring the critical importance of addressing these issues during adolescence. Unfortunately, during this developmental stage, early warning signs and even fully developed clinical conditions often go unnoticed, undiagnosed, and untreated. Nonetheless, there is a lack of established, evidence-backed procedures aimed at reaching out to adolescents at risk of developing emotional disorders. Urgently required is a fundamental shift in our approach by creating intervention protocols that allow for the early identification and treatment of at-risk adolescents, thus averting the potential development of severe mental health disorders as they mature. The selective prevention of mental health issues is a crucial element in assisting at-risk adolescents in flourishing before emotional disorders progress. To address this gap, PROCARE+ was conceived as a modularized selective prevention program for adolescents aged 12 to 18 years. Using a personalized medicine approach, PROCARE+ successfully allowed for the adaptation of intervention protocols according to the specific needs of each individual, while also identifying vulnerable individuals based on risk factors. PROCARE 2.0 aims to enhance the PROCARE+ intervention by maximizing and extending its effects beyond the population in the post-COVID-19 pandemic era. PROCARE 2.0 stratifies adolescents based on their risk and resilience status and will deliver, alongside a core intervention, new specific add-on modules designed to address risk factors identified by adolescents: : 1) Situations of rejection, bullying, and cyberbullying; 2) Addiction to new technologies such as video games or mobile phones and other substances like alcohol, tobacco, and drugs; 3) Improvement of healthy lifestyle habits related to nutrition, sleep, and physical activity; 4) Enhancement of stress-related situations: Ecoanxiety or exam-related anxiety; and 5) Improvement of parent-child relationships and situations of high expressed emotion (parent module). Furthermore, emphasis will be placed on the study of reinforcement sessions to maintain the results following the initial intervention (based on central and additional modules depending on the detected risk factors). Adolescents will be assigned to different experimental groups with or without reinforcement sessions in order to increase the effectiveness of the intervention. PROCARE 2.0, like PROCARE, aims to reduce the impact of risk factors and enhance protective factors that will ultimately lead to lasting positive effects for adolescents. It will combine quantitative analyses, with a special focus on vulnerable groups in a disaggregated approach by sex, gender, sexual orientation, and socioeconomic status. The PROCARE 2.0 project is expected to have a significant impact. Its outcomes will continue to contribute to the identification and preventive treatment of adolescents at risk of emotional mental disorders at an early stage, before they incur personal, social, and economic costs.It will be designed to be an acceptable, scalable, and sustainable selective prevention program, striving to increase its effectiveness beyond the context of the COVID-19 pandemic, ultimately contributing to the prevention and reduction of the prevalence of mental disorders in young people.

Emerging research indicates a link between polycystic ovary syndrome (PCOS) and periodontal diseases, revealing the intricate relationship between oral health and systemic conditions. PCOS, a hormonal disorder in women of reproductive age, often associates with obesity, dyslipidemia, and insulin resistance, heightening the risk for type 2 diabetes (T2D) and cardiovascular disease (CVD). The pathogenesis of PCOS involves an inflammatory response marked by increased CRP, inflammatory cytokines, elevated blood leukocytes, adhesion molecule expression, and oxidative stress markers like myeloperoxidase (MPO). Periodontal diseases, bacterial infections affecting gums, ligaments, cement, and bone, include gingivitis (gum inflammation) and periodontitis (irreversible tissue destruction). Evidence suggests a link between periodontitis and increased CVD risk, while such association with gingivitis is limited. Potential mechanisms linking periodontal diseases and CVD involve cytokine release, oral bacteria toxin production, and direct bloodstream transfer. Recognition of lipopolysaccharide (LPS) and TNFα triggers innate immune cells via TLR4 and TNFR, activating NF-κB and JNK expression. JNK amplifies inflammatory responses, inducing proinflammatory genes, and TNFα, IL-1, IL-6, and IL-8 can invade endothelial layers, promoting adhesion molecule expression. Enhanced leukocyte ROS production, especially in periodontitis, contributes to endothelial dysfunction and heightened cardiovascular risk. The activation of multiple inflammatory pathways likely links PCOS, periodontal disease, and increased cardiovascular risk. Thus, the researchers aim to investigate if the presence of periodontal diseases, particularly gingivitis, exacerbates oxidative stress, inflammation and atherosclerosis surrogate markers in women with PCOS, and explore the underlying molecular mechanisms.
Pain affects the athlete's sporting career directly or indirectly. Directly, the injury affects other areas of the body causing a physical decompensation in the athlete and this affects the correct execution of the sporting technique, or how technical gestures can cause pain. Indirectly, through the psychological consequences of pain that generate a series of negative consequences and feelings. Some studies suggest that psychological skills are an important tool for pain management. For that reason, a mindfulness intervention programme would be a useful tool for manage pain in this population.
