Current oropharyngeal dysphagia (OD) treatment in older patients is based on compensatory strategies (fluid thickening and texture modified diets) that improve swallow safety but do not improve the swallowing function. One of these strategies is thickening products, which are used to reduce pharyngeal bolus velocity by increasing viscosity of fluids. There are several studies demonstrating the therapeutic effect of thickeners in reducing the prevalence of penetrations and aspirations, and their use has been correlated with reduced prevalence of respiratory infections, aspiration pneumonia and hospital readmissions. In recent years, new neurorehabilitation treatment strategies for OD have been developed such as peripheral (electrical or chemical stimulation) or central stimulation (transcranial direct current stimulation or repetitive transcranial magnetic stimulation). The investigators suggest that new generation treatments for OD have to combine thickened fluids and about peripheral stimulation using transient receptor potential (TRP) channels agonists. The aim of this study is to evaluate the therapeutic effect of a cooling sensation (CS) flavor in a pre-thickened oral nutritional supplement (ONS) drink on the biomechanical mechanism of the swallow response in chronic post-stroke patients with OD. The investigators designed a randomized, crossover, interventional and open-label clinical study. The study includes 2 groups: 1) n=25: 1st visit: stimulation with Control, 2nd visit: stimulation with CS; and 2) n=25: 1st visit: stimulation with CS, 2nd visit: stimulation with Control. Each patient will attend a total of 2 visits, with a washing period of at least 7 days between visits. The procedures to be performed during each visit are: clinical assessment of swallowing with V-VST, spontaneous swallowing frequency measurement using electromyography, and collection of a sample of saliva using a Salivette®.
Ambispective post-market data collection on visual symptoms, patient satisfaction and surgeon experience with the TECNIS PC IOL.
The goal of this randomized clinical trial is to compare the adjunctive use of enamel matrix derivatives in the treatment of tooth autotransplantation in terms of clinical attachment level. The main question it aims to answer. What is the benefit, in terms of clinical attachment level and probing depths, of using enamel matrix derivatives adjunctive to tooth autotransplantation? Participants will be subjected to a digitally guided surgery of tooth autotransplantation. The protocol of the test group will be supplemented with the application of enamel matrix derivatives before the placement of the transplanted tooth into the surgically produced alveolus.
Post-stroke rehabilitation of the upper extremity is a challenge in neurorehabilitation. Selective training of different degrees of freedom (training of specific monoarticular movements and in one plane of movement of the upper extremity) to achieve true recovery could be a good approach. However, it is not known how the training should be structured to avoid interference between the different movements trained, hindering the motor learning process during neurorehabilitation. This research aims to determine the effect on performance and kinematic control of a selective movement control task during one- or three-days training of 2 different degrees of freedom, close or distant in cortical representation, of the upper extremity in people with early subacute and chronic phase of stroke. The hypothesis is that in the upper extremity of subacute or chronic phase stroke survivors, learning 1 target DoF is interfered by training another DoF of the same joint. In contrast, learning 1 DoF from a different, distant joint does not interfere with learning the target DoF in a training session. Likewise, this interference is diminished in multiple training sessions. On the other hand, in early post-stroke phase, within the first 5 weeks, the gain in kinematic control of each controlled DoF is greater than in later post-stroke phases (between 9 to 12 weeks of evolution or chronic phase). An experimental design of 4 days of training, of approximately 60 minutes per day, will be carried out in people who are within the first 3 months after a stroke or in a chronic stage. There will be 3 intervention groups that will train the shoulder flexion movement of the paretic upper extremity and another movement, which can be of the same affected upper extremity or another of the contralateral lower extremity.
The purpose of this study is to assess the safety, tolerability, drug levels, drug effects, and impact on disease severity of BMS-986326 in participants with moderate-to-severe atopic dermatitis (AD).
The goal of this randomized clinical trial is to evaluate the effect on the microbiota and the reduction in the number and/or intensity of symptoms of gastrointestinal discomfort of consuming a probiotic or placebo for 6 weeks in adult women and men. The main questions to answer are: 1. To study changes in the alpha diversity of the microbiota. 2. To evaluate changes in the salivary cortisol. For this purpose, a randomized, double blind crossover study has been designed. Target sample size is 30 subjects. Participants will be allocated in two groups for 16 weeks (6 weeks consuming one of the products + 4 weeks wash-out period + 6 weeks consuming the other product). - Group 1 (n=15): 6 weeks daily consumption of one probiotic capsule + 4 weeks wash-out period+ 6 weeks daily consumption of one placebo capsule. - Group 2 (n=15): 6 weeks daily consumption of one placebo capsule + 4 weeks wash-out period+ 6 weeks daily consumption of one probiotic capsule.
The goal of this randomized, double-blind, placebo-controlled, crossover study is to test the effectiveness of 10 kilohertz (kHz) high-frequency transcutaneous stimulation for tremor in people with Parkinson's disease. The main questions it aims to answer are: - Compare the effectiveness between sham stimulation and real stimulation (10kHz) for different types of tremors [rest tremor, postural tremor, kinetic tremor], fine motor skills, and maximal isometric handgrip strength. - Register adverse events, the blinding success of participants and evaluator, and subjective perception of tremor improvement. Participants will perform the following tasks in an "off" state (without levodopa and dopamine agonists medication). All of them were performed on the upper limb with more tremor. - Rest Tremor: Forearm on the armrest, count backward from 100 to 0 as fast as possible for 1 minute and 30 seconds. - Postural Tremor: Extend the arm parallel to the floor (90º shoulder flexion with the forearm extended) for 30 seconds. - Kinetic Tremor: Hold a cup by the handle, raise it close to the mouth for 3 seconds, then return to the initial position. - Fine Motor Skills: Complete the nine-hole peg test, placing pegs into holes as quickly as possible. - Handgrip Strength: Squeeze the device as strongly as possible for 3 seconds, then rest for 15 seconds.
The goal of this cross-over study is to evaluate the physiological response to exercise and body composition according to training status in participants with a wide spectrum of fitness states. The main questions it aims to answer are: - Which are the physiological differences across participants with different training status? - Which are the body composition differences across participants with different training status?

This research project is based on previous studies suggesting that certain components of olive pomace oil can reduce inflammation in the brain associated with neurodegenerative diseases like Alzheimer's. The current hypothesis proposes that particles carrying dietary fats can trigger inflammation, but if they contain bioactive compounds from olive pomace oil, this inflammatory activity will be reduced. The study aims to recruit 40 adult volunteers, both men and women, diagnosed with early-stage Alzheimer's. Participants will be divided into two groups based on their blood triglyceride levels. Additionally, 40 healthy individuals with similar ages will be recruited and divided into two groups based on their triglyceride levels. Recruitment will take place at the Neurology Department of Virgen de Valme University Hospital in Dos Hermanas, Sevilla. Participants must have a mild stage of Alzheimer's, allowing intervention through diet for prevention or slowing down disease progression. Inclusion criteria include good visual and auditory capabilities, disease monitoring by healthcare professionals, and voluntary written consent approved by the hospital's ethics committee. Exclusion criteria involve current medical conditions, medication use (except contraceptives), pregnancy or lactation, systemic diseases, cardiovascular events in the last two years, uncontrolled hypertension in the last six months, cancer in the last five years, recent participation in clinical trials, physical or intellectual limitations, and any connection with the study staff. Participation is voluntary, and participants can withdraw at any time without consequences. The study could benefit Alzheimer's patients by reducing brain inflammation and oxidative stress. For healthcare institutions, it may improve care quality and contribute to prevention and treatment policies. Scientifically, it could provide insights into the effects of compounds on Alzheimer's patients, potentially leading to new treatment strategies. Olive pomace oil producers may benefit from supporting the oil's marketing and usage with health-related information. Overall, the project aims to impact society positively by enhancing disease prevention and treatment. Regarding risks, the study involves minimal blood extraction, posing no significant threat. Participants may experience slight discomfort due to the catheter during the six-hour study period. Follow-up contact may be necessary, but participants have the right to refuse. The study will take place at Virgen de Valme University Hospital (Seville), ensuring immediate attention in case of unexpected issues. A qualified nurse, supervised by a doctor, will conduct the procedures. The study is covered by liability insurance to compensate for any health-related issues or injuries during participation. Two postprandial experiments will be conducted, administering olive pomace oil in one and high-oleic sunflower oil in the other. Blood extractions will occur before and hourly for six hours after participants consume a meal containing the respective oils, accompanied by bread and milk. The food poses no health risks. The blood extraction process involves a simple puncture with inherent risks of any standard blood withdrawal procedure.
