NCT04974632
It is well known that video-assisted thoracoscopic surgery (VATS) is preferred to open surgery for lung resection because of the smaller incisions and optimized postoperative recovery, including a shorter length of hospitalization and much decreased local tenderness. Studies have shown less operative and post-operative morbidity with decreased operative times. However, for small nodules (i.e. lesions \<1 cm or those at a distance more than 1.5cm from the lung periphery), adequate identification of the target nodule has been being difficult by VATS with necessity of more significant resection or thoracotomy conversion to ensure complete tumor resection. In order to improve nodule localization, a variety of preoperative localization methods such as CT-guide hook wire or methyl blue dye localization have been proposed. It has been proved to be much easier to mark lung nodules and help guide resection during VATS. However, there are certain concerns. First, it is difficult to minimize the time between the localization procedure and the subsequent surgery in reality. Second, there is concern for patient safety, in particular pneumothorax or hemothorax, during transferred to and from the ward to the radiology suit and in the frequent delays and waiting in reception areas prior to transfer to operating theaters. Finally, interdepartmental transfers and delays can also increase the risk of hook wire dislodgement. Theoretically, the aforementioned disadvantage could be solved by performing the localization procedure and the lung surgery in the same operating room environment. We performed single-step localization and removal of small pulmonary nodules in the hybrid OR equipped with floor-mounted C-arm cone-beam computed tomography (CBCT) in the previous study. However, it costed a lot of money and every localization could only be performed in the hybrid OR. Mobile 3D C-arm CT is another form of CBCT. It depicts soft tissues with high contrast but also offer a more affordable solution with relative low cost. In this case series, we will investigate the use of a mobile 3D C-arm CT for single-step localization and removal of small pulmonary nodules.

The aim of this study was to investigate the effects of chewing gum before surgery on preoperative anxiety, postoperative gastrointestinal functions (time to first gas, time to first defecation, bowel sounds, abdominal distension) and nausea and vomiting in patients undergoing abdominal surgery. Hypotheses of the Study: In patients undergoing abdominal surgery; H1.1: The first gas output time (hour) is shorter in patients who chew gum before surgery compared to patients who do not chew gum H1.2: The first defecation time (hour) is shorter in patients who chew gum before surgery compared to patients who do not chew gum H1.3: The bowel sounds are heard shorter in patients who chew gum before surgery compared to patients who do not chew gum H1.4: The abdominal distension rate is lower in patients who chew gum before surgery compared to patients who do not chew gum H1.5: The nausea and vomiting rate is lower in patients who chew gum before surgery compared to patients who do not chew gum H1.6: Preoperative anxiety levels of patients who chew gum before surgery are lower than those of patients who do not chew gum Preoperative intervention group patients will chew sugarless gum for at least 30 minutes 30-60 minutes before surgery. The gum will be removed before going to the operating room. No intervention will be performed on control group patients, and standard care will be applied.

NCT04872413
This clinical trial collects and tests samples using genetic testing to find personalized treatments that may work best for patients with mantle cell lymphoma (MCL) that has come back (relapsed) or does not respond to treatment (refractory). Several types of MCL are difficult to treat due to specific genetic changes (mutations or alterations in the DNA/RNA expression in the cells) that make them not respond to a certain type of drug called a Bruton's tyrosine kinase (BTK) inhibitor. The goal of this clinical research study is to use genetic testing to identify which drugs may be most effective in treating patients with MCL who have this type of genetic mutation.

NXT Urodynamics System Post-Market Clinical Follow-up Clinical Investigation to Confirm Ongoing Safety and Performance in Urodynamic Patient Sub-Populations
NCT06838884
Although joint involvement is predominant, RA is a systemic disease that can affect many organs. RA is a disease that includes changes such as inflammation, joint pain, fatigue, increased risk of coronary and heart disease. In patients with RA, exercises should be planned for decreased muscle strength, endurance, aerobic capacity and affected normal joint movements. Aerobic exercise capacity should be measured for individualized exercise planning in rehabilitation. Bicycle ergometer, one of the aerobic capacity tests, has been used in rehabilitation for a long time. Although it is frequently used in rehabilitation, it has some disadvantages. Therefore, other tests such as the step test can be used to eliminate these disadvantages of the bicycle ergometer and to assess functional capacity. The 6-minute step test (6MST), which requires less time and space, can be used as an alternative to assess exercise capacity. Patients will be evaluated at Firat University Hospital. Patients diagnosed with RA, older than 18 years of age and with a body weight of 100 kg or less (maximum weight supported by the stepper) will be included in the study.
NCT06846658
Clinical diagnosis of Parkinson's disease (PD), multiple system atrophy (MSA) and dementia with Lewy bodies (DLB) is challenging, especially in the early stages. Each disease is associated with distinct conformers of misfolded alpha-synuclein (maS) which form typical protein aggregates in the brain and represent key disease biomarkers. Thus, detection and characterization of intracerebral maS aggregates allow a definite diagnosis. The recent development of ultrasensitive assays enabled the detection of maS and other potential new biomarkers in peripheral tissues, although with several limitations. Here, the investigators propose to combine the expertise of leading and young researchers in the field of neurology, structural and molecular biology, biophysics and machine learning to perform ultrasensitive and multi-omics analyses of olfactory mucosa (OM), blood and urine of PD, MSA and DLB patients for detecting and characterizing key peripheral biomarkers allowing accurate disease recognition.
NCT06847880
Brief Summary of the Study This study investigates the effects of locally administered vitamins C and E on orthodontic tooth movement during the initial stage of treatment. Orthodontic tooth movement relies on bone remodeling, which can be influenced by antioxidants like vitamins C and E. Vitamin C promotes collagen formation and osteoblast activity, while vitamin E has anti-inflammatory and antioxidant properties that may impact bone metabolism. The study is a randomized clinical trial conducted in multiple clinics, where patients will be divided into three groups: 1. Control group - receives a saline injection. 2. Vitamin C group - receives a local injection of vitamin C. 3. Vitamin E group - receives a local injection of vitamin E. Injections will be administered every two weeks for six months, while patients undergo orthodontic treatment with fixed appliances. Researchers will evaluate the rate of tooth movement, root resorption, pain perception, and patient experience. Additionally, biomarkers related to bone remodeling will be measured in gingival crevicular fluid at different time points. The study aims to determine whether local administration of vitamins C or E enhances orthodontic tooth movement and elevate their effects on the orthodontic potential side effects like root resorption and pain. The findings may provide valuable insights into optimizing orthodontic treatment with the help of antioxidants.
NCT06848127
This study aims to characterize emotional dysregulation in complex post-traumatic stress disorder (cPTSD) and to determine the extent to which it can promote the distinction with borderline personality disorder (BPD) and post-traumatic stress disorder (PTSD). As emotional dysregulation is a dynamic process whose phenomenological manifestations are labile, associated with physiological modifications and modulated by cognitive processing, a multiple methodology associating measurements in a real-life ecological context with measurements performed in the hospital will be preferred. Overall, this study proposes to capture, for the first time, the clinical manifestations associated with cPTSD from the perspective of emotional dysregulation and its underlying processes
NCT06847295
Spinal cord injury (SCI) is a major cause of morbidity and disability worldwide, significantly impacting patients' quality of life and functional independence. Despite advances in rehabilitation therapies, many individuals with SCI remain unable to stand or walk. Epidural electrical stimulation (EES) has emerged as a promising neuromodulation therapy to restore motor function in individuals with chronic paralysis. This prospective clinical study aims to evaluate the efficacy and safety of EES in patients with chronic SCI who have lost the ability to stand or walk. The primary objective is to assess late-stage gait recovery following the implantation of an epidural spinal cord stimulator, using validated clinical scales such as the Fugl-Meyer Assessment - Lower Extremity (FMA-LE) and BMCA VRI. Secondary objectives include evaluating: The ability to stand independently (measured by the Berg Balance Scale). Improvements in walking capacity, with or without assistance. Changes in spasticity induced by EES (Modified Ashworth Scale). Reduction in pain perception (DN4, Brief Pain Inventory \[BPI\], Pain Disability Index \[PDI\]). Improvements in neurogenic bladder and bowel dysfunction (NBSS and NBDS). Enhancements in quality of life (SCI-QOL, WHOQOL-BREF) and mood (Beck Depression Inventory \[BDI\]). The study will recruit 10 adult patients (ages 18-50) with chronic, stable SCI (≥6 months post-injury) classified as ASIA A or B, with lesions between C7 and T10 and intact segmental reflexes below the injury level. Participants will undergo an intensive 3-month pre-implant rehabilitation program to maximize their baseline motor potential. Following this period, eligible patients will receive surgical implantation of an epidural spinal cord stimulator (Medtronic Specify 5-6-5 paddle lead and Intellis pulse generator). After a 1-month post-surgical recovery period, patients will engage in a 12-month intensive rehabilitation protocol (5 supervised sessions per week), with the stimulator activated to facilitate motor recovery. Patients will be assessed monthly through clinical evaluations and surface electromyography (EMG) to measure motor control improvements. Outcomes will be compared before and after EES implantation to determine the effectiveness of the intervention. This study seeks to provide further evidence on the potential of epidural electrical stimulation in restoring standing and walking abilities in individuals with SCI. If successful, it could contribute to expanding treatment options for patients with chronic paralysis.

NCT05339425
China has gradually entered an aging society, and the incidence of osteoporotic fractures is increasing rapidly. Although the harm of osteoporotic fracture is huge, its diagnostic rate in China is still low. China still lacks a national osteoporotic fracture registration system, which has been established in many countries. The purpose of this study is to establish a Chinese osteoporotic fracture registration network platform (CORN), which will be helpful for the long-term comprehensive management of osteoporotic fracture population in China. This platform will help to establish a large prospective clinical cohort database of osteoporotic fractures and high-risk population in China.
NCT03813862
Greater advances are needed in two separate but related areas in healthcare: 1) the Clinical Decision Support Systems that complement the EHR use in support of routine patient care, population management and disease management; and 2) the use of the point-of-care observational data from the provider-patient encounter that support realworld medical research and healthcare quality measure assessment. Real-world evaluations of treatments of chronic diseases in the context of comorbid conditions and special populations (minorities, women, mentally ill, and those with addiction) are limited. The purpose of the OPERA database is to help address this unmet need in clinical research.
