This randomized clinical trial aims to evaluate and compare the analgesic efficacy and functional outcomes of the quadro-iliac plane block (QIPB) and the pericapsular nerve group (PENG) block combined with lateral femoral cutaneous nerve(LFCN) block in patients undergoing total hip arthroplasty. The primary outcome is the Numeric Rating Scale (NRS) within the first 48 hours after surgery. Secondary outcomes include postoperative total opioid consumption, ıncidence of quadriceps motor block, time to first ambulation, block performance time, falls, length of hospital stay, block- related complications(hematoma,local anesthetic systemic complications, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, and incidence of postoperative nausea and vomiting.

This phase II trial compares the effectiveness of adding BMX-001 to usual symptom management versus usual symptom management alone for reducing oral mucositis in patients who are receiving chemoradiation for head and neck cancer. Oral mucositis (inflammation and mouth sores) is a common side effect of chemoradiation that can cause pain and difficulty swallowing. Usual management of these side effects typically consists of using mouth rinses and pain medications during treatment and for several weeks after completion of treatment. BMX-001 neutralizes harmful substances in the body, preventing damage to macromolecules such as DNA and minimizes free radical-related toxicity in normal tissues. Adding BMX-001 to usual symptom management may be more effective than usual symptom management alone at reducing oral mucositis in patients receiving chemoradiation for head and neck cancer.
NCT07244211
This study is an intervention domain of the Musculoskeletal Adaptive Platform Trial. The primary goal of this pragmatic, randomized, open-label, comparative effectiveness trial is to evaluate if arthroplasty is superior to internal fixation when used to treat minimally displaced femoral neck fractures in older adults ≥60 years old. We hypothesize that arthroplasty will reduce death, preserve ambulation, increase days alive and out of hospital, and improve health status compared to internal fixation within 4 months and 12 months from randomization.
NCT07042477
This project will evaluate a virtual, on-demand telemedicine program for High emergency department (ED) utilizers with comorbid physical health conditions and behavioral health correlates. Researchers will randomize patients to have either full access to the full intervention (treatment group) or to receive only standard care (control group). Analyses will be intent-to-treat. The primary outcome is the number of ED visits 120 days after the first Best Practice Alert (BPA) firing. The research team plans to enroll 3200 patients in this study. However, randomization may end due to system constraints on December 31, 2025 before reaching that target. This sample provides 80% power to detect a 35% relative reduction in ED utilization using a two-tailed test with an alpha of .15, assuming 40% compliance with the program.
NCT07658079
Nutrition is the intake of essential nutrients in sufficient quantities and at the appropriate times to maintain and improve health and enhance quality of life. Enteral nutrition is superior to parenteral nutrition and should be preferred. To protect the gastrointestinal mucosa and maintain normal flora, patients should begin enteral nutrition as soon as possible. In patients who cannot take food orally, enteral nutrition is provided via a nasogastric/nasojejunal tube or gastrostomy tube. Gastrostomy is the first choice for patients with a functional gastrointestinal system, poor oral intake, and requiring long-term nutritional support. Feeding tubes can be placed percutaneously or surgically. Percutaneous endoscopic gastrostomy (PEG) is a minimally invasive procedure that does not increase morbidity or mortality, is cheaper, and saves time compared to surgical gastrostomy. It was first applied in 1980 as an alternative to surgical gastrostomy. During the procedure, a line was defined between the navel and the middle of the left lower costal margin. A feeding tube was then inserted at the junction of the middle 2/3 and the outer 1/3 under local anesthesia, and feeding was started the following day. Vudayagiri et al. reported that the placement site is generally 2 cm medial to the costal margin and 2 cm below the xiphoid process. Different methods for placing a PEG tube into the stomach (pull technique, push technique, and Russell method) have been described in the literature, with the most common being the "pull" technique. The 2005 ESPEN guidelines noted that in the "pull" technique, gastroscopic visualization of the anterior gastric wall is performed, followed by determination of the puncture site at the distal corpus level. The exact location of the PEG feeding tube, both on the skin and within the gastric lumen, is not fully understood. Its localization on the abdominal skin will be optimally achieved through endoscopic transillumination. However, its level within the gastric lumen is predictable. In our study, we aimed to investigate how measuring the distance of the feeding tube from the pylorus in patients undergoing PEG placement affects post-procedure outcomes and to determine the optimal level within the gastric lumen. Additionally, the placement of the catheter on the skin will be recorded in each patient. Traditionally, tube feeding has been delayed until up to 24 hours after percutaneous endoscopic gastrostomy (PEG) procedure. However, results from various randomized controlled trials suggest that early feeding may be an option. A meta-analysis indicated that early feeding (\< or = 4 hours) after PEG placement may be a safe alternative to delayed or next-day feeding. However, although there was no difference in overall complications in this meta-analysis, there was a significant increase in gastric residual volume on day 1 in patients who started early feeding. In another meta-analysis conducted by Szary et al., early tube feeding ≤3 hours after PEG placement; Complications, death within ≤72 hours, or significant gastric residual volume on day 1 were found to be significantly different from delayed or next-day feeding. Our study will be the first of its kind in this field. Therefore, to minimize all factors that could negatively affect the results, we will initiate enteral feeding 24 hours after the traditionally used procedure.

The purpose of the Clinical Procedures To Support Research (CAPTURE) study is to utilize information collected in the medical record to learn more about a disease called amyotrophic lateral sclerosis (ALS) and related disorders.
NCT06847152
Temporal lobe epilepsy (TLE) can cause memory disorders, including long-term forgetfulness due to a failure to consolidate verbal but also spatial information. The forgetting phenomenon presented by these epileptic patients is called accelerated forgetting in the literature and remains difficult to objectify during cognitive assessments. It is indeed particularly complicated to evaluate long-term spatial memory and to account for the topographical complaint, although recurrent, of patients with this TLE. A navigation task being proposed as part of the neuropsychological assessment of patients with a spatial memory complaint, it is interesting to study the performance pattern of patients with TLE by comparing them to a group of control subjects matched in age and gender in order to verify whether there is significant long-term forgetting and whether there is a significant difference between Right TLE and Left TLE. Indeed, several studies have demonstrated this accelerated long-term forgetting in epileptic patients (Cassel et al., 2016; Lemesle et al., 2017; Landry et al., 2022; Blake et al., 2020) but few with a retention delay of several weeks (Tramoni et al., 2009). This study allows us to statistically analyze the effects of these two groups: epileptic patients and healthy volunteers, but also to combine the effect of the laterality of epilepsy specifically on spatial memory performance.
NCT05441982
Animal and observational research in humans suggest that specific types of non-nutritive sweeteners (NNS) may impair glycemic control. However, whether NNS consumption impacts glucose homeostasis in middle-aged/older adults with prediabetes is unknown, and potential mechanisms by which this could occur have yet to be identified. The overall objective of this R21 proposal is to establish proof-of-concept for alterations in glucose homeostasis following intake of saccharin, but not acesulfame potassium, in middle-aged/older adults with prediabetes compared to a eucaloric diet with no NNS.
NCT07624448
The goal of this study is to help children with autism and a co-occurring intellectual disability and their families learn practical strategies for managing issues like irritability, aggression, and other challenging behaviors. The main objective of this study is: To adapt current Regulating Together materials to create an outpatient group program for emotion dysregulation in autism and co-occurring intellectual disability (ASD + ID) that will improve psychosocial outcomes for youth with ASD + ID.
NCT07597213
The goal of this clinical trial is to evaluate whether hyaluronic acid (HA) improves periodontal healing in people with periodontal disease who smoke. Moreover, the effects of HA on biomolecules and bacteria levels will be assessed during the follow up period. The main questions it will answer are: Will periodontal sites treated with HA gel after non-surgical periodontal treatment (NSPT) lead to better outcomes in clinical parameters compared to the sites treated with NSPT only in smokers? Will adjunctive use of HA gel reduce oxidative stress markers and bacteria levels during follow-up? Researchers will compare periodontal sites receiving NSPT with adjunctive HA gel application to sites receiving NSPT alone to determine whether HA provides additional clinical, biochemical and microbiological benefits. Participants will: * first receive full-mouth NSPT then, randomization will be performed in selected jaw to determine the test sites. These two interproximal test sites will additionally receive HA gel application. * attend follow-up visits at 1, 3 and 6 months for clinical periodontal measurements and to provide gingival crevicular fluid samples (GCF) and subgingival samples. The GCF samples will be evaluated for Metallothionein (MT) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels and subgingival samples for periodontal pathogens.
NCT07625150
This project aims to develop an \[18F\] fluorodeoxyglucose (FDG) positron emission tomography (PET) / magnetic resonance imaging (MRI) method to locate the painful inflammation in PFJ OA associated with joint loading. \[18F\] FDG PET/MRI is an emerging pain imaging approach with enhanced sensitivity to painful hypermetabolic inflammation through evaluation of intracellular glucose utilization rate via (\[18F\]FDG PET) and fine anatomy details (MRI). The investigative group has shown its promise in revealing previously unidentified or unspecified pain generators in various musculoskeletal pain conditions. The investigators have also demonstrated the feasibility of visualizing the structural changes between unloaded and loaded knee joints with MRI, which can be easily adopted in the current PET/MRI setting. The main challenge in the proposed \[18F\]FDG PET/MRI approach is to differentiate the normal uptake of FDG for metabolic changes by weight-bearing from abnormal changes indicating eventual pain aggravation by weight-bearing and knee-flexion. The investigators have garnered the following two aims to validate the proposed method by comparing unloaded and loaded knee imaging results between PFJ OA pain patients and asymptomatic, matched controls.
NCT03258554
This phase II/III trial studies how well radiation therapy works with durvalumab or cetuximab in treating patients with head and neck cancer that has spread to a local and/or regional area of the body who cannot take cisplatin. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. It is not known if radiation therapy with durvalumab will work better than the usual therapy of radiation therapy with cetuximab in treating patients with head and neck cancer.

NCT06472518
* Iliofemoral DVTs (IF DVTs) are vascular disorders associated with high morbidity and mortality, which can be complicated by long-term post-thrombotic syndrome (PTS). * Pharmaco mechanical thrombolysis (PMT) is an innovative endovascular technique involving in situ fibrinolysis of the thrombus in the acute phase of thrombosis, followed by mechanical extraction by fragmenting the thrombus. * The American ATTRACT study showed that management by catheter-directed thrombolysis and/or PMT in the acute phase is safe and effective at 2 years in a subgroup of DVTif compared with anticoagulation (18% moderate or severe SPT with thrombolysis vs. 28% without thrombolysis). * PMT-DVT will be the first study to assess the medium (30 months) and long-term (60 months) efficacy of PMT in the French context, using data from the French National Health Data System.
NCT07293195
The goal of this clinical trial is to determine the adjunctive effects of heat therapy and contrast therapy when combined with the Otago exercise program in individuals with patellofemoral pain syndrome aged 18 to 40 years. The study aims to assess whether these interventions can help reduce pain and swelling, improve knee range of motion, and decrease functional limitations associated with patellofemoral pain syndrome. Researchers will compare two groups one receiving heat therapy with the Otago exercise program and the other receiving contrast therapy with the Otago exercise program to see which approach provides greater improvement in outcomes. Participants will undergo regular supervised sessions that include the assigned thermal therapy and a structured set of Otago exercises targeting lower limb strength, balance, and mobility.
NCT07563478
This study is designed to evaluate the effect of gamification-based teaching strategies on learning outcomes and student engagement in undergraduate oral pathology education. Traditional didactic teaching methods in dental education are often associated with passive learning and variable student engagement. In response, educational gamification has emerged as an innovative pedagogical approach that integrates game elements into learning activities to enhance motivation, participation, and knowledge retention. This study employs a crossover interventional design involving undergraduate dental students enrolled in an Oral Pathology course. Participants will be exposed to both traditional teaching methods and gamified learning interventions in a structured sequence, allowing each participant to serve as their own control. The gamified intervention includes the use of an online game designed on Genially to reinforce key concepts in Oral Pathology. The traditional control arm consists of standard lecture-based instruction without gamification elements. The primary objective of this study is to compare knowledge acquisition between gamified and traditional teaching approaches, measured through standardized assessments administered after each intervention phase. Secondary objectives include evaluating student engagement, satisfaction, and perception of learning effectiveness using validated structured questionnaires. The study aims to determine whether gamification enhances academic performance and improves student engagement compared to conventional teaching methods. It also seeks to explore student perceptions of innovative teaching strategies and their potential integration into the dental curriculum. Data will be collected at multiple time points corresponding to each phase of the crossover design. Statistical analysis will compare outcomes between intervention periods, accounting for within-subject variability. The findings are expected to provide evidence-based insights into the effectiveness of gamification in dental education and support curriculum development strategies aimed at improving active learning and student-centered teaching approaches. This study addresses an important gap in dental education research by systematically evaluating gamification using a controlled crossover design, providing robust comparative data between traditional and innovative teaching methods in oral pathology education.
NCT07204925
The goal of this clinical trial is to understand the feasibility and effectiveness of using reinforcement learning to personalize robotic prosthetic legs (an experimental prototype) for unilateral transfemoral amputees. The main questions it aims to answer are: * With the developed RL-based Recommendation Interfacing System (RISE), clinicians are able to personalize prosthetic legs faster compared with existing manual personalization procedures. * With the developed RL-based Recommendation Interfacing System (RISE), clinicians are able to personalize prosthetic legs without detailed knowledge about how the prosthetic legs are controlled. * Patients perform better when the prosthetic legs are personalized with RISE system compared with the ones personalized manually Researchers will compare two arms (RISE guided personalization and manual personalization) to see if the tuning speed will increase and if patients can perform better. Participants will go through the standard prosthetic fitting procedures, such as alignment adjustment, then they will experience repeated prosthesis personalization procedures conducted by tuning specialists without RISE, tuning specialists with RISE, and prosthetists (without tuning expertise) with RISE on different types of terrains. In the end, the participants will go through a testing trial, in which they will experience the prototype personalized through the three different approaches without knowing how the control parameters are decided. Their walking performance will be recorded. It is expected that the participants will visit the testing site 8 times, which including alignment (1 visit), three personalization procedures (twice for each), and one testing trial (1-2 visits).
NCT05063552
This phase II/III compares the standard therapy (chemotherapy plus cetuximab) versus adding bevacizumab to standard chemotherapy, versus combination of just bevacizumab and atezolizumab in treating patients with head and neck cancer that has spread to other places in the body (metastatic or advanced stage) or has come back after prior treatment (recurrent). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Cisplatin and carboplatin are in a class of chemotherapy medications known as platinum-containing compounds. They work by killing, stopping, or slowing the growth of cancer cells. Docetaxel is in a class of chemotherapy medications called taxanes. It stops cancer cells from growing and dividing and may kill them. The addition of bevacizumab to standard chemotherapy or combination therapy with bevacizumab and atezolizumab may be better than standard chemotherapy plus cetuximab in treating patients with recurrent/metastatic head and neck cancers.
NCT06980038
This phase II trial compares the effectiveness of cemiplimab with CDX-1140 to cemiplimab without CDX-1140 prior to surgery in treating patients with stage III-IV head and neck cancer. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. CDX-1140 is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Giving cemiplimab with CDX-1140 versus cemiplimab alone before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed for patients with stage III-IV head and neck cancer.
