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).
NCT07595094
The goal of this observational study is to learn about the ability of Phenotypic Age Acceleration (PhenoAgeAccel) to predict four key health outcomes in Chinese people with or at risk of major chronic diseases: the risk of developing new chronic diseases, the risk of dying, life expectancy, and disease-free healthspan. The main questions this study aims to answer are: * Does higher PhenoAgeAccel increase the risk of developing major chronic diseases (including diabetes, dementia, cancer, and chronic respiratory diseases) in Chinese adults? * Does higher PhenoAgeAccel increase the risk of death from all causes in Chinese adults? * How do life expectancy and disease-free healthspan differ between people with high versus low PhenoAgeAccel? Who can take part in this study? Adults aged 35 or above years old who receive routine care at participating hospitals in China, have complete routine blood test data available, and have provided consent to use their health information for research purposes. What will participants go through? Participants will receive their usual medical care as they normally would. No new treatments, tests, or procedures will be performed specifically for this study. We will collect data from their medical records, including blood test results used to calculate PhenoAgeAccel, diagnoses of new diseases, and dates of death. What are the potential benefits? Participants will not receive direct personal benefits from taking part in this study. However, the information learned may help us better understand biological aging and improve future risk assessment and health management for people with chronic diseases. Is this study safe? Yes. This is an observational study that does not involve any new drugs, devices, or invasive procedures. All data used in the study will be de-identified and kept strictly confidential to protect participants' privacy.
NCT07595809
Heart failure with reduced ejection fraction (HFrEF) is frequently associated with abnormalities in body composition, including reduced skeletal muscle mass and sarcopenia, which are independent predictors of reduced exercise tolerance, impaired quality of life, and increased mortality. Despite advances in pharmacological therapy, evidence-based non-pharmacological strategies aimed at preventing muscle mass loss remain limited. This randomized controlled trial aims to evaluate the effects of dietary intervention based on the DASH diet with high-protein elements, resistance exercise training, and their combination on skeletal muscle mass, functional capacity, echocardiographic parameters, biochemical markers, and quality of life in patients with HFrEF.
NCT07471646
The goal of this interventional study is to examine the effects of Ramadan diurnal fasting alone and in combination with moderate-intensity aerobic exercise on cardiometabolic health in adults with overweight and obesity. The main questions it aims to answer are: 1. Does Ramadan diurnal fasting lead to changes in body composition and cardiometabolic health outcomes? 2. Does adding moderate-intensity aerobic exercise during Ramadan fasting result in greater improvements in cardiometabolic health compared with fasting alone? Participants will be randomly assigned to one of two groups: Ramadan diurnal fasting only or Ramadan diurnal fasting combined with a supervised moderate-intensity aerobic exercise program. Cardiometabolic, metabolic, and behavioral outcomes will be assessed before Ramadan and during the last week of Ramadan.
NCT06651281
Researchers want to learn more about tulisokibart (also known as MK-7240) in an extension study. Tulisokibart is a medicine designed to treat active, moderate to severe Crohn's disease (CD) and ulcerative colitis (UC). An extension study is a type of study where people who received tulisokibart in certain other studies for CD or UC (called a parent study) may be able to join this study. The goals of this study are to learn about the safety of tulisokibart over time in people with CD or UC, and if people tolerate it.

Meningiomas are the most common primary brain tumor, and some groups are diagnosed with higher-grade tumors and have clinically worse outcomes. This study investigates social determinants of health and individual risk factors that may be associated with meningioma.
NCT00825422
Posterior lumbar arthrodesis causes severe postoperative pain, hampering patients's postoperative reconvalescence especially functional rehabilitation. Efficient and safe methods for postoperative analgesia are, therefore, mandatory. The application of opioids are the most frequently used therapies for postoperative pain relief but it very often results side effects. Local anesthetic wound infiltration is widely recognized as a useful adjunct in a multimodal approach to postoperative pain management. In the setting of spine surgery, a single bolus administration of a local anesthetic is a useful method (with a reduction in parenteral morphine consumption during the 48 first hours) but has a limited effect because of its short duration of action. Prolonged administration through a multi-holed catheter positioned by the surgeon at the end of the procedure could increase the duration of action and may thereby improve the efficacy of local wound infiltration. Easy and effective, this new modality of administration has expanded the indications for parietal infiltrations toward major painful procedures. We designed this study to determine whether local anesthetic (compared with saline solution) continuous wound infiltration during the first two days after posterior lumbar arthrodesis on degenerative spine, could improve postoperative analgesia at short-term but particularly at mid-term (two months) and long-term (six months), in order to decrease postoperative lumbar pains (resulting in best life quality, opioid consumption limited and rehabilitation hastened) and postoperative hyperalgesia areas. The postoperative analgesic and antihyperalgesic efficacies; the postoperative rehabilitation at mid-term and long term, and the safety of opioid administration and multi-holed parietal catheter will be compared in the two groups (control and study).
NCT06201832
Cardiac amyloidosis (CA) has recently been reported as a common cause of heart failure with preserved left ventricular ejection fraction (HFpEF), with a prevalence of 6% in elderly HFpEF patients. However, the diagnosis of CA is still challenging and requires multiple costly investigations. Regardless of the type of CA, TTR or AL, early diagnosis significantly improves prognosis. In this study, the investigators aimed to determine the prevalence of CA in Tunisian HFpEF patients and to identify clinical and ultrasound criteria predictive of CA.
NCT07595484
This study was conducted to compare two methods of using temporalis fascia graft in tympanoplasty, namely wet temporalis fascia graft and dry temporalis fascia graft. Tympanoplasty is an ear surgery performed to repair a hole in the ear drum and to improve hearing in patients with chronic otitis media. Temporalis fascia is a thin layer of tissue taken from the area over the temple muscle and is commonly used as graft material for repair of the ear drum. The study included adult patients aged 18 to 60 years who had chronic otitis media with inactive mucosal disease, a large central perforation of the ear drum, and conductive hearing loss confirmed on pure-tone audiometry. Patients were assigned to one of two treatment groups. One group underwent tympanoplasty using a wet temporalis fascia graft, while the other group underwent tympanoplasty using a dry temporalis fascia graft. The main purpose of the study was to assess whether one graft preparation technique gave better surgical and hearing outcomes than the other. The outcomes were assessed three months after surgery. Hearing improvement was measured by comparing the air-bone gap before and after surgery on pure-tone audiometry. Graft success was assessed by otoscopic examination to determine whether the graft had healed properly, remained in correct position, and closed the ear drum perforation. Complete air-bone gap closure was also assessed as an additional hearing outcome.
NCT07596355
This is a prospective observational clinical study designed to evaluate the performance of artificial intelligence (AI) algorithms applied to upper aerodigestive tract (UADT) video-endoscopy. The study assesses three main tasks: lesion detection (localization), classification (benign vs malignant), and segmentation of tumor margins. AI algorithms will be applied to endoscopic video data acquired during routine clinical practice without influencing clinical decision-making. The system will process images in real time and store data for subsequent analysis. AI outputs will be compared with physician assessment and reference standard histopathology to evaluate diagnostic performance.
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.

NCT07595900
Non-Lactational Granulomatous Lobular Mastitis (NL-GLM) is an inflammatory disease of unknown etiology, characterized clinically by local breast masses, accompanied by redness and swelling of the overlying skin, sinus tract formation, and other symptoms. Currently, there is no universally accepted standard treatment for this condition; previous expert consensus or practice guidelines have mostly recommended systemic glucocorticoid therapy as the primary treatment approach. Our team's preliminary research has confirmed that local glucocorticoid injection achieves efficacy equivalent to systemic administration but with better safety, making it a first-line treatment option for NL-GLM. However, in our preliminary studies and literature reports, we found that some patients still exhibit glucocorticoid dependence or resistance (i.e., refractory NL-GLM) after receiving either local or systemic glucocorticoid therapy. The lack of high-quality evidence to support subsequent-line treatments has become a major bottleneck in clinical management. Additionally, some patients cannot tolerate glucocorticoid therapy due to its adverse effects. Research has shown that the IL-6 inflammatory pathway is significantly activated in the lesion tissues and peripheral blood of NL-GLM patients, and the IL-6 inhibitor tocilizumab has demonstrated efficacy in various autoimmune diseases. Based on this, this study intends to conduct a dual-center, single-arm clinical trial to systematically evaluate the efficacy and safety of tocilizumab in the treatment of refractory NL-GLM. The aim is to fill the treatment gap, provide high-level evidence for clinical practice, and ultimately improve patient outcomes.

Cohort 2: To track the onset and progression of a condition called chemotherapy-induced peripheral neuropathy (CIPN) and to test a certain type of experimental neuromodulation (stimulation of the brain) with a device called a closed-loop brain-computer interface (clBCI) to see if can help to prevent pain due to CIPN.
NCT06302868
The purpose of this study is to assess the feasibility of conducting a randomized controlled efficacy trial comparing the delivery of exposure therapy via a telemedicine-based virtual reality clinic (Doxy.me VR) vs. standard telemental health (TMH) to adults with intense fear of dogs, snakes, and/or spiders. The secondary purpose is to preliminarily examine the efficacy of using Doxy.me VR vs. TMH in reducing phobia severity.
NCT06369064
In patients requiring renal replacement therapy (RRT) in the intensive care unit (ICU), continuous techniques are predominantly using due to better hemodynamic tolerance. The most employed techniques in ICU are continuous venovenous hemodiafiltration (CVVHDF) and continuous venovenous hemodialysis (CVVHD). To our knowledge, there are no prospective studies comparing the efficiency of these two techniques with the same dose of dialysis (and the same filter). In the CompEER study, we aim to compare the efficiency of CVVHD and CVVHDF on urea reduction rate in intensive care patients with acute kidney injury. The research hypothesis is that CVVHD citrate technique is as effective as CVVHDF heparin technique for urea reduction and provides prolonged and stable clearance, facilitating antibiotic management during RRT.
NCT07593651
Recent advances in breast surgery, together with the increasing adoption of conservative surgical approaches, have renewed interest in pre-pectoral implant-based breast reconstruction. Within this reconstructive paradigm, surgeons may employ two distinct strategies: (i) immediate reconstruction using a direct-to-implant approach (DTI), or (ii) a two-stage reconstruction consisting of tissue expander placement followed by definitive implant insertion (TE-I). Each approach is associated with specific indications, advantages, and inherent limitations. The EXPRESSO study aims to retrospectively compare surgical outcomes between pre-pectoral DTI and TE-I breast reconstruction. By providing real-world evidence on these reconstructive strategies, this study seeks to inform surgical decision-making and to optimize reconstructive outcomes in contemporary breast cancer care.
NCT07321041
The goal of this observational study is to evaluate the effect of neonatal delivery time on umbilical cord blood gas parameters in pregnant women undergoing elective cesarean section under general or spinal anesthesia. The study population consists of adult pregnant women aged 18-40 years with singleton term pregnancies scheduled for elective cesarean delivery. The main questions it aims to answer are: Is neonatal delivery time associated with changes in umbilical artery pH values under general and spinal anesthesia? Is neonatal delivery time associated with changes in umbilical artery base excess under general and spinal anesthesia? Researchers will compare cesarean sections performed under general anesthesia with those performed under spinal anesthesia to determine whether the relationship between delivery time and umbilical cord blood gas parameters differs between anesthesia techniques. Participants will: Undergo elective cesarean delivery under general or spinal anesthesia as part of routine clinical care Have neonatal delivery time recorded intraoperatively Have umbilical artery blood gas parameters (pH and base excess) measured immediately after birth as part of standard neonatal assessment
NCT07593352
The NEPHRO-IBD study is a multicenter prospective observational study designed to evaluate the prevalence of renal dysfunction and renal complications in adult patients with inflammatory bowel disease (IBD) compared with individuals from the general population. Although extraintestinal manifestations are common in IBD, renal involvement remains relatively underrecognized and insufficiently studied. The study will recruit approximately 6,000 participants, including 3,000 patients with confirmed IBD (Crohn's disease or ulcerative colitis) and 3,000 individuals without IBD serving as a control group. Participants will undergo routine clinical assessment, including laboratory tests, urinalysis with measurement of the albumin-to-creatinine ratio (ACR), and imaging evaluation of the kidneys and urinary tract. Disease activity in patients with IBD will be assessed using validated clinical indices. The study will also evaluate the relationship between renal dysfunction and disease activity, medications used in IBD treatment, and comorbidities. The results of this study are expected to improve the understanding of renal complications in patients with IBD and support earlier identification and management of kidney disease in this population.
NCT05527574
One of the most common problems in people with diabetes (DM) and chronic kidney disease (CKD) is the high frequency of other coinciding medical conditions such as osteoporosis and frailty. Frailty in particular is very common in adults with DM and CKD and it can result in significant muscle weakness which can result in increasing difficulties with performing activities of daily life (ADL). This can lead to an increase risk for falls, bone fractures and increasing hospitalization. The investigators have showed that adults with DM and CKD who have frailty use hospital services more frequently, have reduced quality of life and difficulties with performing their ADLs1. There is some evidence that early screening for frailty and lifestyle interventions that focus on healthier eating and physical activity can help prevent frailty from getting worse. The study purpose is to develop and test a home-based lifestyle intervention program focused on optimizing diet and the ability to perform your ADLs in adults with DM and CKD. The goal of this program is to ensure that adults with DM can live healthier lives within the community.
