NCT07567651
Glaucoma is a group of conditions characterised by a progressive loss of retinal ganglion cells (RGCs) and their axons, leading to characteristic changes in the optic nerve head and the retinal nerve fibre layer. If left untreated, the disease has a natural course that can lead to progressive and significant impairment of visual function. Intraocular pressure (IOP) is the main modifiable risk factor for the onset and progression of the disease. The positive effect of surgery on the progression of glaucoma is certainly due to the reduction in IOP levels achieved in the post-operative period, with probable secondary effects on ocular haemodynamics as well. Although IOP reduction is now considered the most potent neuroprotective treatment for glaucoma, it has been shown that good tonometric control may, in some cases, not be sufficient to preserve visual function. There are, in fact, pressure-independent mechanisms involved in the pathogenesis of glaucomatous damage, in which the progressive deterioration and apoptosis of RGCs are linked to mechanisms such as oxidative stress, glutamate neurotoxicity, the inhibition of anterograde transport of neurotrophic factors, and mitochondrial dysfunction. In recent years, various molecules, including cytidine-5'-diphosphocholine (citicoline), have been proposed in combination with hypotensive therapy due to their neuroprotective and neuroenhancing effects. In addition to its structural action, it possesses a functional action (neuroenhancer) as it increases the synthesis of neurotransmitters such as noradrenaline, acetylcholine, serotonin and dopamine, which are involved in visual signal transmission at both the retinal and post-retinal levels. To date, there is no scientific evidence regarding the effect of citicoline on visual function in glaucoma patients who have undergone filtration surgery. Therefore, the hypothesis of this study is that if surgery increases the likelihood of an improvement in the function of residual RGCs, citicoline could help achieve this objective either by increasing the proportion of patients showing improvement or by increasing the extent of the improvement. The use of a placebo is ethically justified because all patients involved in the study, having signed an informed consent form, will undergo surgical treatment - which is considered the treatment of choice for progressive glaucoma - and the efficacy of citicoline treatment needs to be validated in terms of its ability to alter the course of the disease.
NCT07556770
The purpose of this observational study is to evaluate and compare the anatomical safety margins of the subclavian vein using ultrasound. Medical professionals commonly use the subclavian vein to insert central venous catheters, but nearby vulnerable structures, such as the lung and artery, can be at risk during the procedure. This study investigates two different ultrasound probe positions: supraclavicular (above the collarbone) and infraclavicular (below the collarbone). It also examines how changing the patient's arm position (from resting in a neutral position to being raised at a 90-degree angle) affects the distance between the vein and these vulnerable structures. Participants are adult patients scheduled for surgery under general anesthesia who already require ultrasound-guided vascular access. Immediately after falling asleep from anesthesia, researchers will perform a brief 3 to 5-minute ultrasound scan of the collarbone area. This is a strictly non-invasive imaging study; no research-related needle punctures or catheter insertions will be performed. The findings aim to provide robust anatomical evidence to make future vascular procedures safer for patients.
NCT05538286
Postoperative rebleeding is a major limitation of surgical evacuation for intracerebral hemorrhage (ICH). While computed tomography (CT) is the standard of care for postoperative hematoma cavity monitoring, CT requires significant physical and financial costs. Studies have demonstrated varying degrees of efficacy when using transcranial ultrasound to measure ICH volume. Recently, synthetic implants for cranioplasty have been shown to be safe and sonolucent. This study aims to evaluate the ability of transcranial ultrasound with sonolucent cranioplasty (TUSC) to detect and quantify bleeding in postoperative ICH patients.
NCT04333537
This phase II/III trial studies how well sentinel lymph node biopsy works and compares sentinel lymph node biopsy surgery to standard neck dissection as part of the treatment for early-stage oral cavity cancer. Sentinel lymph node biopsy surgery is a procedure that removes a smaller number of lymph nodes from your neck because it uses an imaging agent to see which lymph nodes are most likely to have cancer. Standard neck dissection, such as elective neck dissection, removes many of the lymph nodes in your neck. Using sentinel lymph node biopsy surgery may work better in treating patients with early-stage oral cavity cancer compared to standard elective neck dissection.
NCT04481204
This is a phase II study using the Bayesian platform design. There are three clinical stage groups of localized pancreatic cancer: resectable, borderline resectable, and locally advanced disease. Each stage group will have a defined standard of care chemotherapy regimen for a control arm, serving as a basis of comparison. Each group may have one or more experimental arms. Experimental arms may be added to the platform over time, and the effects of the experimental treatments will be tested against the controls for each group.
NCT07564310
Obstructive sleep apnea (OSA) is common and associated with impaired daytime functioning, reduced quality of life and increased cardiovascular, metabolic and perioperative risk. Mandibular advancement devices (MADs) are a guideline-supported, non-invasive alternative to CPAP for patients with mild to moderate OSA and for those with severe OSA who refuse or cannot tolerate CPAP. MAD therapy relies heavily on patient engagement and sustained use over time. However, in usual care, patients typically have limited access to objective information about their treatment response. Titration is often based on intermittent assessments and subjective symptom reporting, with little real-time feedback to patients on treatment effectiveness. This lack of visibility may limit patient understanding of their condition, reduce engagement with therapy, and delay optimisation of treatment. Advances in nocturnal oximetry now enable multi-night, home-based assessment of oxygen desaturation and related metrics. The myNarval CC solution provides patients, alongside clinicians, with access to objective oximetry data during MAD therapy. By increasing patient awareness of treatment response, this approach has the potential to enhance engagement, support adherence, and improve the overall treatment experience. The purpose of this study is to evaluate whether access to oximetry data through the myNarval CC solution improves patient-reported experience measures (PREMs) compared with standard care in patients treated with MADs for OSA.
NCT07563283
Why is this study being done? Chronic Obstructive Pulmonary Disease (COPD) causes airflow blockage creating breathing issues, distress, and lower well-being. COPD also causes hyperinflation of the lungs. The investigators are doing the study to learn more about improving lung function for patients with COPD by using voice-based experiences. What is being tested in this study? If singing/vocalizing can improve lung function. How long will I be in the study? The study will last 4 weeks and involve 2 in-person visits to KUMC with virtual vocal sessions two times a week over Zoom.
NCT07565766
The goal of this clinical trial is to evaluate the effect of a mouthrinse containing an active ingredient benzydamine hydrochloride in the absence of daily oral hygiene. The study includes periodontally healthy female subjects and experimental phase will last for three days. Plaque accumulation is the primary evaluated outcome, measured by a particular periodontal index called Plaque Control Record (PCR). Gingival inflammation (bleeding) is the secondary evaluated outcome, measured by a particular periodontal index called Bleeding on Probing (BoP). Researchers will compare benzyadamine hydrochloride mouthrinse to a placebo (a look-alike substance that contains no active ingredient) mouthwash to see whether benzydamine hydrochloride use results in greater plaque accumulation.
NCT03860233
This study will investigate if an intra-nasal nose spray of the drug oxytocin can decrease the amount of pressure needed from the automatic Continuous Positive Airway Pressure (CPAP) device while sleeping decreasing some of the harmful effects of low oxygen in people with sleep apnea. This study will last 35 nights and involves spending three nights in the sleep lab at George Washington University. There are no additional costs to participants and no compensation for being involved in the study.
NCT07563569
compare the impact of type of anesthesia on ERCP including technical success, rate of complications, peri procedural safety, patient and endoscopist satisfaction in adult patients with obstructive jaundice
NCT07563348
This randomized controlled trial (RCT) with a pretest-posttest design aimed to determine the effect of a game-based escape room teaching method on intern nursing students' knowledge levels regarding pressure ulcers. The study was conducted at the Faculty of Nursing, Aydın Adnan Menderes University between March and December 2025. A total of 56 senior nursing students were randomly assigned to either the intervention group (n = 28) or the control group (n = 28). The intervention group received both theoretical instruction and escape room-based learning activities, while the control group received only traditional lecture-based theoretical instruction. Data were collected using the Student Information Form, the Pressure Ulcer Knowledge Assessment Tool 2.0 (PUKAT 2.0-T), and the Gameful Experience Scale (GAMEX). The primary outcome was the change in pressure ulcer knowledge levels measured using the Pressure Ulcer Knowledge Assessment Tool 2.0 (PUKAT 2.0-T) across three time points: baseline, immediately after theoretical instruction, and 1 month after the intervention.
NCT07565272
This study aims to evaluate the usability, user experience, and tolerability of a virtual reality-based rehabilitation game platform specifically developed for individuals with Duchenne muscular dystrophy. Participants will complete a single-session gameplay experience using an immersive virtual reality headset with hand-tracking technology. Following the gameplay session, usability, enjoyment, and potential virtual reality-related discomfort will be assessed using standardized questionnaires and qualitative feedback. The study is exploratory and formative in nature and does not aim to evaluate clinical effectiveness.
NCT07562386
In this randomized controlled trial, we will evaluate if bipolar enucleation of the prostate (BEEP) is associated with better urinary voiding outcome than transurethral resection (TURP) in men with enlarged prostate referred to surgery. In addition we will investigate the association between symptom relief and the amount of removed tissue and if patients experience differ between the two methods. Finally, we will assess cost-effectiveness of BEEP compared to TURP. The main outcome for comparison of the two surgical methods is International Prostate Symptom Score (IPSS) assessed at 12-month follow-up. The primary outcome to assess patient experience is measured with the questionnaire Nordic Patients Experience Questionnaire (NORPEQ). Cost-effectiveness will be measured with incremental cost-effectiveness ratio (ICER).
NCT07160478
Musculoskeletal pain during childhood can negatively affect school attendance, physical activity, and social participation. This study will evaluate the effectiveness of the school-based health education program 'SocLaLola', which uses a comic-based narrative to introduce children to pain science concepts and promote healthy lifestyle habits. The intervention will be compared with a standard program focused on sedentary behavior prevention. Students aged 8 to 11 years from two primary schools will participate. The primary objective is to determine whether SocLaLola is more effective than the comparison program in improving children's knowledge about pain and in reducing fear-avoidance beliefs related to physical activity.
NCT05838638
The purpose of this study is to examine the effectiveness of a technology-based intervention for managing nausea and vomiting in older adults with cancer. Participants will be randomized to either an intervention or control group. Outcomes such as symptom severity, quality of life, and resource use will be examined.
NCT05308732
This study aims to propose an alternative and auxiliary methodology for the prevention and treatment of Oral Mucositis (OM) in patients undergoing radiotherapy or radio and chemotherapy for head and neck neoplasms through the use of copaiba-based mouthwash, since the treatment that currently has proven efficacy for the prevention of OM(Low Power Laser Therapy) cannot be applied in tumor regions due to the risk of stimulating the tissue proliferation of malignant cells.
NCT06120764
The goal of this randomized controlled study is to assess the effect of guided imagery on chemotherapy-related nausea and vomiting in pediatric oncology patients. Participants will receive either guided imagery+routine care or routine care. The researchers will compare nausea and vomiting and vital signs between groups.
NCT07535060
This study aims to evaluate the effectiveness of soft tissue augmentation using connective tissue graft (CTG) in pontic site defects. It compares clinical and volumetric outcomes between sites with an existing fixed partial denture (FDP) and sites without an FDP. Following tooth extraction, alveolar ridge resorption often leads to soft tissue defects that can compromise esthetics, function, and prosthetic outcomes. CTG is considered the gold standard for soft tissue augmentation due to its predictable improvement in tissue thickness and stability. In this non-randomized clinical trial, patients with single edentulous sites in the esthetic zone will undergo CTG using a standardized surgical technique. The primary outcome is keratinized tissue thickness, while secondary outcomes include keratinized tissue width, volumetric soft tissue changes, esthetic evaluation (Pink Esthetic Score), plaque index, post-operative pain, and patient satisfaction. Clinical and digital assessments will be conducted preoperatively and at follow-up intervals up to 6 months. The study aims to determine whether performing CTG around an existing bridge provides comparable or improved outcomes compared to sites without a bridge, potentially offering a less invasive alternative to prosthetic replacement.
NCT05527171
To evaluate the effect of virtual reality mindfulness meditation on patients after ACLR, the investigators will determine the effect of virtual reality mindfulness meditation to 1) decrease self-reported injury-related fear, 2) improve poor jump-landing movement patterns, and 3) improve brain activity in women 1 to 5 years post-ACLR when compared to a virtual reality sham group.
NCT06422676
