NCT06426108
Molar incisor hypomineralization (MIH) manifests as a qualitative, demarcated defect in tooth enamel of systemic origin, predominantly affecting one or more permanent first molars, and potentially extending to the incisors. One significant challenge in managing this enamel anomaly is hypersensitivity, leading to discomfort and pain in affected patients. Low-intensity laser therapy, alone or combined with other modalities, appears promising in alleviating pain associated with MIH. This study aims to assess the efficacy of low-intensity laser therapy using varied parameters, in conjunction with a remineralizing agent, for pain management in children with molar incisor hypomineralization. Participants aged 6 to 12 years will be recruited, with a total of 88 teeth diagnosed with MIH, presenting a sensitivity score ≤3 on the Visual Analog Scale (VAS) and a score ≤1 on the Schiff Cold Air Sensitivity Scale (SCASS). The teeth will be randomly assigned to one of four groups (n=22 each): Group I (GI): L-1J + VF, Group II (GII): L-1J + VP, Group III (GIII): L-2J + VF, and Group IV (GIV): L-2J + VP. Here, 'L' denotes low-intensity laser application at different parameters (1J and 2J), combined with either fluoride varnish (VF) or a placebo varnish (VP). Interventions and assessments will be conducted initially, after 48 hours, and at 1 and 2 weeks post-treatment. Patients will undergo re-evaluation at 2, 4, 8, and 12 weeks following interventions. Statistical analyses will be performed with a 95% confidence level (α = 0.05).

Eligible participants include patients aged ≥5 years undergoing strabismus surgery for esotropia, exotropia, or vertical deviations, with best-corrected visual acuity (BCVA) of 6/12 in both eyes. Patients with previous strabismus surgery, amblyopia, neurological conditions, or sensory strabismus will be excluded.
NCT06913907
Methotrexate is known to exist intracellularly as methotrexate polyglutamate, which is formed by the addition of glutamic acid after absorption into the body. The objective of this study is to measure the concentration of methotrexate polyglutamate in red blood cells and peripheral blood mononuclear cells after initiating methotrexate treatment in patients with rheumatoid arthritis who have no prior history of using methotrexate (either subcutaneous or oral formulations). Additionally, we aim to examine changes in methotrexate polyglutamate concentrations when switching from oral methotrexate to subcutaneous Metoject, as well as to investigate the relationship between methotrexate polyglutamate concentration and the efficacy and safety of the treatment. Another objective of this study is to evaluate whether switching to subcutaneous Metoject allows for an increased maximum tolerable dosage while maintaining safety.
NCT06913920
This single-blinded, randomized controlled trial (RCT) will evaluate the added benefit of mechanical modalities (continuous passive motion (CPM) and intermittent pneumatic compression (IPC)) when integrated into standard therapy for managing postoperative edema and pain in patients undergoing distal radius fracture (DRF) fixation. The primary outcomes are edema volume (measured via volumeter) and pain intensity (Numeric Pain Rating Scale, NPRS) at 6 weeks post-operation. Secondary outcomes include wrist/forearm range of motion (ROM), grip strength, Patient-Rated Wrist Evaluation (PRWE), and adverse events.
NCT05038527
The purpose of this prospective trial is to investigate ABM/P-15 bone graft versus traditional bone graft in patients undergoing surgery for Adult Spinal Deformity (ASD) in order to provide better clinical results through faster bone healing, no additional surgeries, fewer complications and thereby increase health-related quality of life. Main hypotheses: 1. The use of ABM/P-15 bone graft is superior to traditional bone graft treatment regarding the incidence of additional surgeries following index surgery for ASD Secondary hypotheses: 2. The investigators expect non-inferiority in patient reported outcome measures in the ABM/P-15 bone graft group compared to the control group 3. The investigators expect non-inferiority in the postoperative fusion rates (bone healing) evaluated on CT scans in the ABM/P-15 bone graft group compared to the control group 4. The investigators expect non-inferiority in postoperative incidence of asymptomatic pseudarthrosis in the ABM/P-15 bone graft group compared to the control group 5. The investigators expect non-inferiority in perioperative complications in ABM/P-15 bone graft group compared to the control group 6. The investigators expect the use of ABM/P-15 bone graft to be cost-efficient compared to the traditional treatment in the control group
NCT06377228
The main aim of the trial is to learn how well adults with refractory lupus nephritis (LN) or refractory systemic sclerosis (SSc) tolerate TAK-007 and to check for side effects (adverse events). Other aims are to learn how effective treatment with TAK-007 is in adults with refractory LN or refractory SSc, what effects TAK-007 has on the human body, and whether participants will produce antibodies against TAK-007.
NCT03604185
Hearing loss has been associated with decreased emotional wellbeing and reduced quality of life in aging adults. Although hearing aids can target aspects of peripheral hearing loss, persistent perceptual deficits are widely reported. One prevalent example is the loss of the ability to perceive speech in a noisy environment, which severely impacts quality of life and goes relatively unremediated by hearing aids. Musicianship has been shown to improve aspects of auditory processing, but has not been studied as a short-term intervention for improving these abilities in older adults with hearing aids. The current study investigates whether short-term choir participation can improve three aspects of auditory processing: perception of speech in noise, pitch discrimination, and the neural response to brief auditory stimuli (frequency following response; FFR). Sixty hearing aided older adults (aged 50+) recruited from the Greater Toronto Area will be randomly assigned to one of three conditions: a choir singing class (n=20), a music appreciation class (n=20), and a do-nothing control group (n=20). Choir participants will take part in a singing class for 14 weeks, during which they will take part in group singing (2 hours/week) supported by individual online musical training (1 hour/week). Participants will undergo pre- and post-training assessments, conducted during the first week of the choir class and again after the last week. Participants in the music appreciation class will be involved in 14 weeks of music listening classes, and the do-nothing control group will not engaged in an active intervention. All participants will undergo the same battery of assessments, measured before and after the 14-week time frame. Auditory assessments (speech perception in noise and pitch discrimination tests) will be administered electronically, and the FFR will be obtained using electroencephalography (EEG). Each of the four assessment sessions (two pre-training, two post-training) will last approximately 1.5 hours, for a total of 6 hours of data collection. The goal of this research is to investigate whether short-term musical training will result in improved auditory outcomes for older adults with hearing aids. It is predicted that the choir singing group will demonstrate the greatest improvements across all auditory measures, and that both the choir singing and musical appreciation groups will experience greater improvements than the do-nothing control group.
NCT06914310
Memantine has shown promise in mitigating secondary brain injury in previous studies. One study demonstrated that early memantine administration in moderate TBI patients resulted in lower serum neuron-specific enolase levels and improved Glasgow Coma Scale scores. However, other trials investigating memantine's impact on long-term cognitive function in TBI patients have yielded mixed results. There is a need for well-controlled studies to determine the efficacy of memantine in improving neurological and cognitive outcomes in patients with TBI.
NCT06860477
This study will evaluate the efficacy and safety of cryoablation combined with lenvatinib plus Tislelizumab compared with FOLFOX in patients with advanced Intrahepatic Cholangiocarcinoma (ICC) who have progressed after first-line treatment.
NCT04335487
This study evaluates two Internet-delivered cognitive behavioural therapy (ICBT) interventions: one for symptoms of posttraumatic stress disorder (PTSD) and one for symptoms of anxiety, depression, and PTSD. Both interventions have been tailored for Canadian public safety personnel (PSP). Outcomes of interest include preference for disorder-specific or transdiagnostic care, engagement with the interventions, changes in symptoms and functioning, and strengths and limitations of implementing ICBT with Canadian PSP.
NCT04127032
This study evaluates a transdiagnostic Internet-delivered cognitive behavioural therapy (ICBT) recently tailored for Canadian public safety personnel (PSP) reporting symptoms of depression, anxiety, or posttraumatic stress. Outcomes of interest include engagement with the intervention, changes in symptoms and functioning, and strengths and limitations of implementing ICBT with Canadian PSP.
NCT04516343
The overall objectives of this work is to establish feasibility of a robotic ankle assist device (RAAD) to improve mobility in free-living settings and to establish the RAAD as an effective tool to provide increased dose and precision of targeted ankle therapy. The first specific goal is to assess the benefits of repeated gait training with RAAD assistance. Individuals with CP will participate in a 4-week assistance intervention and mobility outcomes will be quantified pre and post intervention. The second specific goal is to separately assess the benefits of repeated gait training with RAAD resistance. Individuals with CP will participate in a 4-week resistance intervention and mobility outcomes will be quantified pre and post intervention. Assessed separately, it is hypothesized that both assistance and resistance training will improve mobility outcomes.
NCT06911190
This study aims to assess longitudinal data in 170 adult and 30 pediatric genetically and clinically well-defined facioscapulohumeral dystrophy (FSHD) patients. FSHD is a chronic progressive disorder associated with major disability due to loss of function and independence. The clinical variability of FSHD is partially explained by currently known (epi)genetic factors. Identifying the variables that influence the clinical variability is essential for developing targeted therapies. Furthermore, it is crucial to assess the natural course, determine sensitive outcome measures and biomarkers to prepare for future trials. Objective This is a longitudinal study on 200 Dutch FSHD patients with a follow-up of ten years. We will hereby assess the natural disease course; determine the sensitivity to change of clinical outcome measures and muscle imaging; validate newly developed outcome measures; and help identify biomarkers and modulators of disease severity. Study population: Genetically proven FSHD patients: All 162 patients that participated in the FSHD-FOCUS study, together with all 18 pediatric patients that participated in the iFocus study , and additional 65 newly included patients. Main study parameters/endpoints: Natural history will be assessed by 'traditional' clinical outcome measures: Motor Function Measure D1, Ricci-score, MRC scores and FSHD clinical score for adults. Additionally in children shoulder dysfunction performance of upper limb and Facial weakness score will be assessed. Natural history will also be quantified using newer clinical outcome measures and patient-reported measures: Reachable workspace, FSHD-RODS and FSHD Facial Function scale in adults. In children, Reachable workspace and FSHD-COM Peds will be assessed. Muscle MRI and ultrasound will be performed to determine progression of fat replacement, fibrosis, and muscle inflammation. Furthermore, blood samples will be taken in adult participants for (epi)genetic analysis on disease modifying factors, and for storage in the Radboudumc biobank for future research (e.g. on biomarkers). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participants will be asked for a visit to the outpatient clinic at the department of neurology. Their medical history will be taken and they will undergo a clinical examination. Several questionnaires can be completed at home through on online system (Castor). Blood samples will be collected in adult patients, a magnetic resonance imaging (MRI) of muscles of both legs (in adults and adolescents) and muscle ultrasound of multiple skeletal muscles will be performed. Spirometry will be performed in a small subset of adult participants. We classify the risk of this study as negligible.
NCT06912464
The goal of this study is to assess how safe it is for critically ill patients in the Intensive Care Unit (ICU) to undergo a PET scan. A PET scan is a type of medical imaging used to help determine why a patient is sick. It is similar to a CT scan but involves a small amount of radioactivity to highlight areas of concern in the body. For a PET scan, patients need to be transported from the ICU to the scanning room, which can be risky because ICU patients are often very fragile. After a patient gets the PET scan injection, their body gives off a small amount of radiation for a short time. Because of this, doctors and nurses have to keep some distance to protect themselves. This means they keep an eye out for the patient from a bit further away than normal. This makes the procedure slightly riskier, especially for very sick patients. This study aims to answer the question: Is getting a PET scan riskier for ICU patients than a regular CT scan? All patients in this study will continue to receive their usual critical care. Researchers will closely monitor the scanning process to evaluate its safety. PET scans are already widely used to detect cancer, but new advancements may allow us to use them more often to diagnose infections. Before this can become routine practice, we need to ensure that PET scanning is just as safe as other commonly used imaging techniques. This study will assess all ICU patients undergoing a PET scan-regardless of the reason for the scan-to determine how safe the procedure is in critically ill individuals.
NCT06910072
This is a prospective, single-arm, multicenter study to observe and evaluate the efficacy and safety of paclitaxel polymeric micelles and carboplatin in combination with iparomilimab and tuvonralimab in neoadjuvant therapy for triple-negative breast cancer. The main endpoint of the study is pCR, 32 patients are scheduled to be enrolled.
NCT06366620
Disruptive behavioral disorders are common in early childhood, affecting up to 15% of preschool-aged children. Behavioral parent training programs are a first-line evidence-based treatment for child disruptive behaviors. There is evidence showing that (a) these programs are effective in reducing disruptive behavior and improving long-term outcomes, and (b) there is an excellent return on investment for early intervention. Nevertheless, there is limited availability of behavioral parent training programs, particularly in rural settings, due to shortages of trained clinicians. Thus, there is a pressing need for expanding the mental healthcare workforce in rural/underserved areas. The study will involve an established parent-based behavioral intervention (First Approach Skills Training for Behavior; or FAST-B) with added pilot component incorporating parents who have previously been through parent behavioral management training programs as Peer Supports.
