NCT07233616
The prevalence of severe chronic venous insufficiency (CVI) is significant in the growing octogenarian population. While radiofrequency ablation (RFA) is a standard minimally invasive treatment, robust data on its outcomes and safety profiles specifically in patients aged 80 years and older remain scarce. This study aims to evaluate the risks and benefits of RFA in this specific, high-risk demographic.This prospective, single-arm, single-center cohort study will enroll 50 patients (initial target sample size) aged ≥80 years with CVI classified as CEAP C3 to C6 and with confirmed great or small saphenous vein reflux. All participants will undergo endovenous RFA under tumescent local anesthesia. The primary outcomes are: 1) the great/small saphenous vein occlusion rate at 6 months, assessed by duplex ultrasonography, and 2) the change in disease-specific quality of life from baseline to 6 months, measured by the Aberdeen Varicose Vein Questionnaire (AVVQ). Secondary outcomes include occlusion rates at 1 and 3 months; complication rates (e.g., deep vein thrombosis, skin burns, paresthesia) within 30 days; and changes in the Venous Clinical Severity Score (VCSS) and the 12-Item Short Form Health Survey (SF-12) at predefined intervals over 6 months.This study is designed to demonstrate a high technical success rate (occlusion rate \>95% at 6 months) and a statistically significant improvement in AVVQ and VCSS scores at 6 months post-procedure. The collected data will provide a detailed profile of complication rates, characterizing the safety of RFA in this very elderly cohort.This study will provide crucial, prospective evidence regarding the efficacy and safety of RFA for treating CVI in octogenarians. The findings are expected to guide clinical decision-making and inform treatment guidelines for this vulnerable and expanding patient population.

NCT05762172
Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain. The use of 18F-DOPA PET is another option available to oncologists. Many studies on gliomas showed the superiority of this imaging technique over contrast-enhanced MRI. However, this imaging solution has been very poorly studied for brain metastases. The new PET technology equiped with silicon detectors makes it possible to obtain greater sensitivities than those of previous generations. It also make possible to obtain images in very short acquisition times. After injection, the hardware allows to obtain the perfusion kinetics of the lesion thanks to a very short temporal sampling (i.e. three seconds). The main objective of this pilot study is to evaluate the association between early activity measurements (\< 4 minutes post-injection) of 18F-FDOPA in PET and the differential diagnosis between radionecrosis and recurrence of cerebral metastases treated by radiotherapy.

Primary endpoints focus on gas dynamics, inhalation recording accuracy, device integrity, and user tolerability.
NCT07192536
The ANCHOR study is testing a novel, non-invasive brain stimulation program designed specifically for Veterans experiencing concurrent post-traumatic stress disorder (PTSD) and chronic pain. These conditions often occur together and can greatly impact daily life. Current treatments options for PTSD and chronic pain are limited, may come with severe side-effects, and often take weeks if not months to see results. In this study, participants will receive an intensive one-week course of intermittent theta burst stimulation (iTBS), a Health Canada-approved technology already used for depression. In this study, it is being tested for its potential to reduce both PTSD and chronic pain symptoms. This clinical trial will recruit 30 Veterans, all of whom will receive the active treatment (there is no placebo). Participants will receive 5-6 sessions of iTBS per day (each treatment lasts approximately 3 minutes) over a period of 5 days (one week total duration). Researchers will track changes in PTSD symptoms, chronic pain, mood, anxiety, daily functioning, and cognitive performance at 4 time points: baseline (before treatment), at the end of treatment ( end of week 1), and at 2 follow-up assessments (3 weeks and 6 weeks after the end of treatment). The goal of this study is to determine whether this unique brain stimulation program is able to treat concurrent PTSD and chronic pain in Canadian Veterans. This study also aims to lay the groundwork for larger trials that could expand access to innovative treatments for the Veteran community.

NCT07162688
Study Title: A Study on the Effects and Mechanisms of Omega-3 Polyunsaturated Fatty Acids on Acute Graft-Versus-Host Disease (aGVHD) Following Allogeneic Hematopoietic Stem Cell Transplantation Study Type: Open-label, randomized, single-center proof-of-concept clinical trial Objective: To evaluate the immunomodulatory and metabolic effects of Omega-3 polyunsaturated fatty acids (PUFAs) in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT), and to explore their potential in preventing and mitigating acute graft-versus-host disease (aGVHD). Study Population: More than 30 patients aged 18-65 years undergoing allo-HSCT. Intervention: Daily intravenous infusion of Omega-3 lipid emulsion at 2 mL/kg (equivalent to 0.2 g/kg of fish oil), administered in combination with medium/long-chain fat emulsion, starting from the conditioning regimen until neutrophil and platelet engraftment or up to Day +35. Primary Endpoint: Incidence and severity of aGVHD within 100 days post-transplant. Secondary Endpoints: Immune reconstitution (changes in T, B, and NK cell subsets) Lipid and metabolic regulation (TC, TG, HDL-C, LDL-C, TBA) Incidence and severity of infections Overall survival (OS) and progression-free survival (PFS) Statistical Analysis: Chi-square/Fisher's exact test, Kaplan-Meier survival analysis with log-rank test, multivariate regression, metabolomics and transcriptomics (PCA, PLS-DA), and pathway enrichment and correlation analyses. Expected Outcome: Omega-3 supplementation is expected to reduce the incidence and severity of aGVHD by modulating immune responses and metabolic processes, thereby providing a novel preventive strategy for post-transplant complications.

Cancer is a fatal disease characterized by uncontrolled growth and proliferation of tissues and organs in the human body. Among cancer treatments, chemotherapy is the most commonly used treatment method. The drugs used in chemotherapy cause vascular toxic effects during administration, frequent blood samples taken from the patient, antibiotic treatments applied, parenteral nutrition treatments. Subcutaneous venous port catheter (SCVPK), which is a permanent and long-term vascular access route that can be used for medical purposes and in emergency situations, is a frequently preferred and safe intravenous access route because it is not visible outside the body, is well tolerated by the patient, and has a low risk of infection. However, invasive procedures such as port needle insertion and replacement can also cause pain, anxiety and changes in vital signs in patients. Nowadays, the use of non-pharmacological approaches as well as pharmacological methods is increasing in the management of symptoms such as anxiety before the invasive procedure and pain during application in patients receiving chemotherapy treatment. These approaches improve the quality of life of patients and have a positive physiological effect. One of these approaches is sujok therapy. In Su Jok application; The reflection points of the organs are on the hands and feet. These points reflect to the body organ in that area and healing occurs. By finding the right point, energy flow is provided by massaging with appropriate applicators. This research will be conducted to examine the effect of Sujok therapy on pain intensity and anxiety level in cancer patients who have undergone port catheter placement. The research will be conducted as a randomized experimental and placebo study with a pretest-posttest control group in the oncology service of Fethi Sekin City Hospital. 90 (30 experimental, 30 control, 30 placebo) cancer patients who accept the research and meet the sample criteria of the study will be subjected to port catheter application. Application areas for pain, anxiety and stress before the port catheter to the patients in the experimental group will be determined with the help of a probe (diagnostic stick), and seeds will be added to these points approximately 45 minutes before the application and fixed with a patch. For cancer patients in the placebo group, the same procedure will be performed with seeds that have a neutral effect on the body. No procedure will be applied to the patients in the control group. Patient Information Form, General Comfort Scale (GAS), Visual Analog Scale -Pain (VAS-P), Visual Analog Scale -Anxiety (VAS-A) and State-Trait Anxiety Scale were used as data collection tools. (DSKÖ) scale will be used. SPPS 21.0 (Statistical Programme for Social Sciences) package program will be used to evaluate the data obtained from the research. It is thought that if the objectives of the study are achieved, it will help reduce the level of pain and anxiety that may occur during and after port catheter application. In addition, it will contribute to the professional advancement of the project manager, which is a career development project. The positive results in this study will guide other interventions to increase the comfort level of cancer patients who will undergo port catheterization and reduce the level of pain and anxiety.
NCT06315933
In the past, a large number of animal studies have suggested that anesthesia exposure has potential neurotoxic effects, resulting in persistent cognitive and behavioral deficits. At present, there is still a lack of sufficient clinical research evidence to prove whether anesthesia exposure has long-term effects on neurodevelopment. The existing clinical research data suggests that a single short-time anesthesia exposure in young children does not affect long-term neurodevelopmental outcomes. Early onset scoliosis, including congenital scoliosis, is a type of scoliosis deformity that occurs before the age of 10. Posterior scoliosis correction surgery is one of the common treatment. There is currently no research indicating the impact of early single or multiple long-duration anesthesia exposure on the neurological development of children with congenital scoliosis. The aim of this study is to determine the long-term effect of general anesthesia exposure on neurocognitive function and behavior in children with congenital scoliosis, in order to provide reference for related clinical work.

This project will rely on the established multi-center cooperation platform for total valve disease and based on the Carpentier classification, which is newly proposed and widely recognized by the academic community, and will specifically target the population with coronary heart disease combined with Ischemic Mitral Regurgitation（IMR） to conduct a nationwide, multi-center, single valve disease, prospective cohort. Research. From November 2025 to December 2025, 6,000 patients with coronary heart disease combined with moderate or above IMR were consecutively selected from outpatients or inpatients in 21 regional medical centers across the country, and clinical characteristics, imaging data, and serology were collected. Information, drug/surgical intervention status and clinical outcome indicators were included in the clinical follow-up at baseline, 3 months, 6 months, 12 months and 24 months respectively. The main research objectives are to describe the disease characteristics, treatment status and clinical outcomes of coronary heart disease patients with IMR; to evaluate the current application status of GDMT strategies in IMR diagnosis and treatment practice and its impact on mid- and long-term prognosis. The secondary research objectives are to identify factors affecting prognosis, construct a risk stratification model for mid- and long-term prognosis, and discover new molecular markers. This project will for the first time construct the world's largest clearly defined cohort of coronary heart disease combined with IMR. Its research results can provide high-quality data and decision-making basis for precise diagnosis and treatment of IMR populations. Therefore, this project has important scientific research value and clinical guidance significance.

Meralgia Paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN), characterized by pain, numbness, hyperesthesia, or hypoesthesia, especially in the anterolateral thigh where the nerve has a sensory distribution. TheLFCN passes between the psoas and quadratus lumborum muscles in the iliac fossa and enters the thigh under the inguinal ligament by passing through the anterior superior iliac spine over the iliacus muscle. It superficially spreads over the sartorius muscle and receives sensation in the anterolateral thigh. Ultrasonography (US) is frequently used by physiatrists in the diagnosis and interventional treatment of musculoskeletal diseases. MP is usually diagnosed with clinical symptoms such as burning, tingling, pain, and dysesthesia in the anterolateral thigh. Electromyography, US, and magnetic resonance imaging are helpful in diagnosis. US is an easy-to-apply, inexpensive method in daily practice, providing great comfort to clinicians in determining etiology and differential diagnosis. Treatment may include patient education, avoiding tight belts, losing weight, conservative treatment methods, use of non-steroidal anti-inflammatory drugs, local anesthetic and/or steroid injections, surgical neurectomy, neurolysis or transpositions. However, in recent years, there have been case series showing that radiofrequency ablation (RF) can also be applied. The aim of this study is to compare the effectiveness of RF ablation of the lateral femoral cutaneous nerve with steroid injection in patients with clinically diagnosed MP and confirmed by US.

NCT04908449
The purpose of this study is to determine if ultrasound-guided bilateral pectointercostal fascial plane blocks with bilateral rectus sheath blocks block decrease pain scores, decrease opioid consumption, improve respiratory function, and improve quality of recovery in patients recovering from elective cardiac surgery involving primary median sternotomy and mediastinal chest tubes in comparison to pectointercostal fascial plane blocks alone.
NCT07230002
While clinical assessment of locomotor function in this population is carried out using tasks involving walking in a straight line without any obstacles, it does not take into account ecological situations (i.e., situations comparable to real-life situations) in which the person interacts with their environment, such as walking down a street with other pedestrians, which is fundamental to everyday life. This research therefore aims to study the social navigation skills during locomotion of people who have suffered a moderate or severe head injury in the chronic phase in more ecological tasks. This will provide a better understanding of the difficulties encountered by these patients during locomotor interactions in everyday life.
