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 Bonebridge (BB) is a partially implantable active transcutaneous bone conduction hearing system manufactured by MED-EL Elektromedizinische Geräte Gesellschaft m.b.H. (MED-EL, Innsbruck, Austria). The BB augments hearing by providing acoustic input to the inner ear via bone conduction. In 2017 Hodgetts & Scollie introduced a new fitting algorithm called DSL-BCD. The DSL-BCD algorithm was developed especially for the characteristics of bone conduction devices (BCD). If there is a benefit on the patient level in hearing outcomes when comparing the application of DSL-BCD in comparison to DSL v5 when using the BB, was not yet investigated. The aim of this clinical study is to show the improvement in audiological performance and subjective satisfaction with the BCI602 and SAMBA 2 audio processor in patients with conductive hearing loss compared to the unaided condition and to evaluate performance differences through application of 2 different fitting algorithms, namely DSL v5 and DSL-BCD.
Objectives: Primary: To determine the efficacy of periodontal treatment on mental health outcomes in patients with major depression and periodontitis. Secondary: To identify the effect of periodontal treatment on oral, periodontal, and fecal metagenomic microbiomes, and on systemic levels of inflammation (bacterial, viral, and fungal) and their impact on mental health outcomes. Material and method: A 6-month pilot randomized controlled clinical trial is designed. The study will be conducted in patients with moderate or severe DM (Patient Health Questionnaire-9 [PHQ-9] index of 9 or higher) and stage III-IV periodontitis who will be assigned to two different interventions: - Test group: standard periodontal treatment consisting of two sessions of supragingival and subgingival debridement (steps 1 and 2) under local anesthesia. - Control group: periodontal treatment consisting of two sessions of supragingival debridement (step 1) under local anesthesia. The study will consist of 6 visits: - Screening visit (v0) - Baseline visit (v1): - In the mental health center: patients will receive a structured clinical interview for the DSM-IV (SCID) and the patient will fill out a series of specific scales on a study-specific electronic device [Beck Depression Inventory (BDI); UCLA Loneliness Scale, Center for Epidemiologic Studies Depression scale [CES-D]; Childhood Trauma Questionnaire short form (CTQ-SF); The World Health Organization Quality of Life questionnaire (WHOQOL); Hamilton scale (HAM-D17); Global Assessment of Functioning (GAF) Scale]. - At the UCM School of Dentistry: patients will receive a complete periodontal examination (clinical and radiographic). A subgingival microbiological sample, a saliva sample and a blood sample will also be taken. - At the participant's home: the stool samples will be deposited by the participants at home in the specific collection vial. - Intervention visits (v2-3): Two periodontal treatment sessions (test or control) will be carried out one week apart. - Re-evaluation visit (v4): Six weeks after treatment, all periodontal clinical variables will be recorded. - Follow-up visits at 3 and 6 months: after periodontal treatment, all the variables recorded at the baseline visit will be taken Statistical analysis: Periodontal treatment (test/control) will be considered as the independent variable and the Hamilton scale (HAM-D17) will be considered the primary response variable. The rest of the variables will be considered as secondary variables. A crude bivariate analysis of comparison of means or proportions will be carried out depending on the nature of the variable. In addition, crude and adjusted regression models will be performed.
The concentration of 16% carbamide peroxide is the highest concentration that European regulations allow for use in home whitening (Council directive 2011/84/EU). This concentration allows for faster results, but instead patients may suffer more frequently from dental sensitivity. The most commonly described side effect of all whitening procedures is the appearance of dentin hypersensitivity, hence the efforts to counteract or overcome this adverse effect. The objective of the study is to clinically evaluate the difference in dental hypersensitivity produced by home dental whitening treatment using 16% carbamide peroxide in a tray for two hours daily applied daily or every other day for three weeks.
This is a prospective, open-label, multi-center, single-arm study planned to enroll 200 subjects with heterogeneous emphysema and collateral ventilation (CV) in the target lobe. Subjects will undergo instillation of AeriSeal Foam in the target lobe and subsequent assessment of CV status using Chartis Pulmonary Assessment System. Subjects with CV- status will then undergo placement of Zephyr Valve in the target lobe for bronchoscopic lung volume reduction (BLVR) and be followed for 24 months.
This is a Phase III, multicentre, randomised, double-blinded, placebo-controlled, parallel group study to evaluate the safety, tolerability and effect of 1 or 2 mg baxdrostat versus placebo, administered once daily (QD) orally, on the reduction of systolic blood pressure in approximately 720 participants aged ≥ 18 years with hypertension, despite a stable regimen of 2 antihypertensive agents at baseline, one of which is a diuretic (uncontrolled hypertension); or ≥ 3 antihypertensive agents at baseline, one of which is a diuretic (treatment-resistant hypertension).
Human immuno-deficiency virus (HIV) is the virus that causes Acquired Immuno-Deficiency Syndrome (AIDS). HIV disease is considered to be a chronic disease requiring lifelong therapy. The purpose of this study is to assess change in disease activity, adverse events, tolerability, and how the drug moves through the body. Budigalimab and ABBV-382 are investigational drugs being developed for the treatment of HIV disease. Participants are placed in 1 of 5 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 7 chance that participants will be assigned to placebo (A placebo is not a drug and it is not expected to have any chemical effects on your body and it is not designed to treat any disease or illness). Approximately 140 adult participants living with HIV disease on stable antiretroviral therapy (ART) willing to undergo Analytical Treatment Interruption (ATI) will be enrolled at approximately 90 sites worldwide. Participants will receive 4 doses of IV budigalimab or placebo combined with 3 doses of IV ABBV-382 or placebo for an 8 week dosing period. Participants need to be stable on antiretroviral therapy to participate in the study. If participant qualifies to the study, on the day they receive the first injection, participants will be asked to stop antiretroviral medications (also referred to as analytical treatment interruption or ATI) for 52 weeks or until meeting specific criteria to restart antiretroviral medications. Participants will undergo a closely monitored ART interruption. Protocol-defined ART restart criteria includes participant's request. Participants will be followed for up to approximately 52 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. There will be an option for virtual or home health visits for some of the follow-up visits. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
Parkinson's disease (PD) is the second most common neurodegenerative condition worldwide, characterised by motor symptoms, but with other symptoms such as visual impairment. The aim is to compare visual function between PD patients and healthy subjects in order to adequately characterise the visual capabilities of the PD population and perform oculomotor or perceptual therapy to find optometric solutions to slow down the visual impairment they suffer from or minimise their visual symptoms. In the first phase, non-invasive tests will be carried out, such as measuring visual acuity, refraction, pupil diameter in different lighting conditions, sensory dominance, contrast sensitivity, colour vision, stereopsis, reading speed, binocular vision, eye movements and influence on quality of life. In the second, visual oculomotor or perceptual exercises will be performed in a group of PD patients to assess whether there is stabilisation of impairment or improvement of these visual skills. These will be performed in a non-invasive way using simple and easy-to-use instruments or an application on an electronic device could be used. Finally, in the third phase, those visual skills that have been treated will be re-evaluated to assess possible changes, compared with a group of PD patients who have not undergone the visual exercises.
Determine the diagnostic quality of the CIPA tool, in inpatients with stays longer than three days, in the observation of risk of malnutrition compared to the gold standard GLIM as a diagnosis of malnutrition.
Chronic watery diarrhoea is a very common problem in the population and most of these patients will be referred for colonoscopy. If no macroscopic findings are observed during colonoscopy to justify the diarrhoea, serial colonic biopsies will be taken to rule out Microscopic Colitis (MC). However, it has been estimated that only 10-15% of these patients will be diagnosed with MC after colonoscopy. Therefore, about 80% of the biopsies collected and analysed will not be useful to establish a diagnosis, considerably increasing costs. To predict the risk of developing MC, a new promising clinical scoring system has been recently developed. This score will be useful in the diagnostic work-up of chronic watery diarrhoea to prioritize colonoscopy with stepwise colonic biopsies in patients with a positive highly specific score for MC. In cases with a negative score, colonoscopy plus biopsies should be performed only if other diagnostic tests are negative. The aim of this current study is to externally validate the new scoring system to predict MC in patients with chronic watery diarrhoea.
This is a prospective, multicenter, interventional study assessing CE, in patients already scheduled for colonoscopy at tertiary referral hospitals, as a technique to reduce the number of unnecessary colonoscopies and identify patients to prioritize in endoscopy waiting lists.
