This three-year research project aims to test the hypothesis that strain and displacement characteristics of human soft tissues are influenced by (1) habitual physical activity, (2) functional impairment, and (3) training interventions. Over the three years, the ulnar collateral ligament of the elbow, the ankle tendon, and the hamstring muscles will be investigated sequentially. Ultrasound speckle-tracking techniques will be employed to verify these hypotheses and to provide a basis for clinical risk assessment of injury, development of therapeutic strategies, and evaluation of rehabilitation outcomes. In the first year, strain and displacement of the medial ulnar collateral ligament (MUCL) in both longitudinal and transverse directions during passive isokinetic elbow valgus loading will be analyzed in baseball pitchers at high and low injury risk and in healthy controls. The results will be compared with ultrasonic shear-wave elastography. Participants will then undergo an 8-week low- to moderate-intensity blood-flow restriction resistance training program. This phase is expected to characterize ligament mechanical adaptations to long-term sports training, elucidate the relationship between such adaptations and injury risk, and evaluate the effects of resistance training on enhancing medial elbow joint stability. In the second year, individuals with posterior tibial tendon dysfunction and healthy controls will be examined. Longitudinal strain and displacement, as well as transverse rotation and displacement of the tibialis posterior tendon during active ankle movements will be quantified and compared with shear-wave elastography measurements. These results are expected to clarify the relationship between tendon strain-displacement behavior and tendon dysfunction, provide mechanistic insights into tendon pathology, and inform optimal therapeutic strategies. In the third year, patients following anterior cruciate ligament (ACL) reconstruction will be investigated. Longitudinal strain and displacement of the hamstring graft donor site, specifically the semitendinosus muscle-tendon unit, following eccentric training will be assessed and compared with shear-wave elastography and electromyography. This phase is expected to characterize post-harvest semitendinosus muscle activity patterns and their associations with postoperative muscle strength deficits. By integrating findings across the three phases, the anticipated clinical implications of this project include determining whether: 1. adaptive responses of ligaments to repetitive tensile loading during long-term sports participation (including strain behavior and mechanical properties) can serve as screening indicators for injury risk, and evaluating the effects of blood-flow restriction resistance training in these populations; 2. three-dimensional strain, displacement, and rotation of tendons in response to muscle contraction and joint motion are associated with tendon dysfunction; and 3. strain and displacement characteristics of the semitendinosus muscle (in relation to muscle recruitment) can be improved through postoperative functional training following its use as a graft source.

NCT07484295
Background Physiotherapists are increasingly expected to act as first-contact practitioners in many healthcare systems. With the growing expansion of direct access to physiotherapy services, clinicians must be able to identify serious medical conditions that require referral to a physician rather than physiotherapeutic treatment. These conditions are commonly described as "Red Flags." Red flag screening refers to the clinical process of identifying signs and symptoms that may indicate serious underlying pathology such as malignancy, fracture, infection, neurological compromise, or cardiovascular disease. Failure to recognize these conditions may delay appropriate medical care and can pose a significant risk to patient safety. Despite the growing responsibility of physiotherapists in primary care settings, research suggests that screening competencies among physiotherapy students and early-career clinicians may vary considerably depending on the structure and emphasis of educational programs. Many physiotherapy curricula still primarily focus on musculoskeletal management, while structured training in clinical screening and differential decision-making remains inconsistently implemented. In response to these developments, international professional organizations such as the International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) have published clinical frameworks and recommendations emphasizing the importance of systematic screening in physiotherapy practice. However, empirical research investigating how screening competencies can be effectively developed and assessed during undergraduate physiotherapy education remains limited. This gap in the literature represents an important challenge for physiotherapy education and patient safety. The overarching goal of this PhD project is therefore to investigate whether digitally standardized, video-based training and assessment approaches can improve red flag screening competencies among physiotherapy bachelor students.
NCT07409987
This research was conducted to evaluate the effect of electrostimulation and compression applications on the severity, number, and pain levels of neuropathy symptoms and the quality of life of patients with metastatic gastrointestinal cancer receiving oxaliplatin-based treatment in the management of chemotherapy-induced peripheral neuropathy. The study population consisted of patients with gastrointestinal cancer between 2025-2026 . Data collection tools were administered to patients who met the inclusion criteria and developed chemotherapy-induced peripheral neuropathy. Patients were then stratified by age and gender and assigned to "control group, electrostimulation group, compression group, and electrostimulation+compression group" using block randomization. Statistical power analysis determined the total number of participants in the study as 140 patients, with 35 patients in each group. Patients in the control group benefited from the clinic's standard procedures and received no intervention

The purpose of this study is to determine whether continuous glucose monitoring is sensitive to quantifying the glucose response related to consumption of a starchy vegetable (potato) in combination with or separate from consumption of herbs and spices at the same meal.
NCT07089771
People with inflammatory bowel disease (IBD), such as ulcerative colitis or Crohn's disease affecting the colon, have a higher risk of developing colon cancer over time. To catch early signs of cancer, regular colonoscopies are recommended. In this study, the investigators are comparing two advanced methods of examining the colon during these surveillance colonoscopies. One method uses a special dye sprayed inside the colon to highlight abnormal areas (called dye-based chromoendoscopy). The other method uses new technology built into the camera to enhance the view without needing any dye (called virtual chromoendoscopy). Both methods use modern, high-definition equipment. The purpose of this study is to find out if the newer, dye-free method is as good as the traditional dye method at detecting pre-cancerous changes (called dysplasia) in people with IBD. Adults with IBD who are due for a routine surveillance colonoscopy may be invited to take part. Participants will be randomly assigned to one of the two methods. No additional procedures are involved, and only the way the colon is viewed differs. The investigators will also look at how long the procedures take, how many biopsies are needed, any complications, and how patients experience the exam. Participants will be followed over time using national health records to check for long-term outcomes. This research will help doctors better understand which method is most effective and comfortable for patients, and may guide future recommendations for cancer screening in people with IBD.
NCT00024804
This study has four objectives: 1) to provide investigators the opportunity to study bone specimens from patients with various skeletal diseases; 2) to treat patients with skeletal diseases at the NIH; 3) to expose NIH trainees to certain skeletal diseases; and 4) to gain more knowledge about skeletal diseases and stimulate further study of bone biology. Anyone with a disease that affects the skeleton may be eligible for this study. All evaluations, tests, procedures and treatments given study participants are used in the standard care of skeletal diseases. No experimental evaluations or treatments are offered. Patient evaluations include a medical history, review of medical records and routine physical examination. Based on the findings, other procedures may be recommended, including blood tests, urine tests, and imaging tests, such as X-rays, bone densitometry, bone scan, computed tomography (CT) and magnetic resonance imaging (MRI). Bone specimens from participants will be collected for research use. Specimens will be obtained from bone removed during a patient s planned surgical procedure performed for medical care, or patients may be requested to have a bone biopsy removal of a small piece of bone tissue as part of the patient evaluation procedure.
NCT00937937
This phase II trial is studying the side effects and how well dinaciclib works in treating patients with stage IV melanoma. Dinaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
NCT01167712
This phase III clinical trial studies two different dose schedules of paclitaxel to see how well they work in combination with carboplatin with or without bevacizumab in treating patients with stage II, III or IV ovarian epithelial cancer, primary peritoneal cancer, or fallopian tube cancer. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bevacizumab is a type of drug called a monoclonal antibody and blocks tumor growth by stopping the growth of blood vessels that tumors need to grow. It is not yet known whether giving paclitaxel with combination chemotherapy once every three weeks is more effective than giving paclitaxel once a week in treating patients with ovarian, primary peritoneal, or fallopian tube cancer.
NCT03698019
This phase II trial studies how pembrolizumab works before and after surgery in treating patients with stage III-IV high-risk melanoma. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab before and after surgery may work better compared to after surgery alone in treating melanoma.
NCT04491942
This phase I trial identifies the best dose, possible benefits and/or side effects of BAY 1895344 in combination with chemotherapy in treating patients with solid tumors or urothelial cancer that has spread to other places in the body (advanced). BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cisplatin and gemcitabine are chemotherapy drugs that stop the growth of tumor cells by killing the cells. Combining BAY 1895344 with chemotherapy treatment (cisplatin, or cisplatin and gemcitabine) may be effective for the treatment of advanced solid tumors, including urothelial cancer.
NCT05169398
EUS-guided biliary drainage is gaining popularity as a means of achieving endoscopic drainage in patients with failed endoscopic retrograde cholangiopancreatography (ERCP) 1. EUS-guided hepaticogastrostomy (HGS) is a type of EUS-guided biliary drainage and the procedure is employed when the ERCP fails due to a malignant bile duct obstruction but the papilla is inaccessible or if the first of the duodenum is infiltrated by tumor. Recently, a novel dedicated HGS (Niti-S, Taewoong Medical, Gyeonggi-do, Korea) has become available, the stent has a novel design to that prevents the stent from migration, further improving the safety. The aim of the current study is to evaluate the feasibility and outcomes of the novel lumen apposing stent for EUS-guided HGS. The hypothesis is that the device is safe and effective.
NCT05397457
As far as breast cancer is concerned, chemotherapy (CT) is an important treatment. However, there are many adverse effects impairing the patient's quality of life (QOL), in which chemotherapy-induced alopecia (CIA) affects up to 65% of the patients. This condition is reversible. Nevertheless, it takes several months after CT for visible hair regrowth. Different characteristics of the new hair are common; for example, 65 percent of the patients have experienced a graying, curling, or straightening effect. Besides, the emotional trauma due to alopecia can not be neglected. Currently, scalp cooling is the only available and verified management for prevention. Unfortunately, the success rate of scalp cooling is variable, especially among the patients receiving anthracycline-based combinations. Low-level light therapy (LLLT) has been proven as a therapeutic technique for adrenergic alopecia. Recently, investigators have checked the validity of LLLT for the CIA. Although the preliminary outcome showed failure at accelerating hair recovery, technical progress of LLLT may improve the end result. Specifically, LLLT is a technique that utilizes laser diodes (LD) or light-emitting diodes (LED) to promote tissue repair. The light source from LD is coherent while LED is an incoherent light source. Therefore, LDs can deliver energy to tissues more efficiently than LEDs. To comprehensively evaluate the beneficial effect of LLLT in treating CIA, we conduct a clinical trial with a more advanced device equipped with 69 LDs. The project aims to explore the effect of low-level light therapy in chemotherapy-induced alopecia. We expect the therapy will lead to an improvement in the patient's hair count, hair width, and quality of life after chemotherapy.
NCT05564403
This phase II ComboMATCH treatment trial compares the usual treatment of modified leucovorin, fluorouracil and oxaliplatin (mFOLFOX6) chemotherapy to using binimetinib plus mFOLFOX6 chemotherapy to shrink tumors in patients with biliary tract cancers that have spread to other places in the body (advanced) and had progression of cancer after previous treatments (2nd line setting). Fluorouracil is in a class of medications called antimetabolites. It works by slowing or stopping the growth of cancer cells in the body. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It works by killing tumor cells. Leucovorin may help the other drugs in the mFOLFOX6 chemotherapy regimen work better by making tumor cells more sensitive to the drugs. Binimetinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps to stop or slow the spread of tumor cells. Giving binimetinib in combination with mFOLFOX6 chemotherapy may be effective in shrinking or stabilizing advanced biliary tract cancers in the 2nd line setting.
NCT06126276
This phase II ComboMATCH treatment trial compares the effect of neratinib to the combination of neratinib and palbociclib in treating patients with HER2 positive solid tumors. Neratinib and palbociclib are in a class of medications called kinase inhibitors. They work by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of tumor cells. Giving neratinib and palbociclib in combination may shrink or stabilize cancers that over-express a specific biomarker called HER2.
NCT06430957
Obstructive sleep apnea (OSA) is a sleep-related respiratory dysfunction. The prevalence of OSA is increasing with the increasing rates of obesity and elderly population worldwide. Perioperative anesthesia management should be adjusted to improve patient safety in patients with OSA. In OSA patients, positive pressure ventilation support may be required in the preoperative period, various ventilation strategies may be required in the intraoperative period, different pharmacologic agents may need to be avoided, and intensive care unit follow-up or noninvasive ventilation support may be required in the postoperative period. However, it is reported that a significant percentage of OSA patients remain undiagnosed. ASA (American Society of Anesthesiologists) has reported the criteria that should be questioned in order to determine the risk of patients in terms of OSA and to initiate the diagnostic process in risky patients and to make appropriate anesthesiologic arrangements in the perioperative period. In addition, the STOP-BANG assessment scale, which is widely used all over the world in OSA risk assessment, is also used in OSA risk assessment. It is thought that dental caries and extraction needs may be higher in OSA patients, especially since open-mouth sleeping accompanies the situation. In this respect, it is also important for patients to be diagnosed with OSA as it may prevent dental damage due to open-mouth sleeping in the future. Identifying patients at risk for OSA and directing them to the diagnostic process is very important for patient safety. Within the scope of the study, the criteria recommended by ASA and STOP-BANG score will be evaluated and recorded. Risk stratification in terms of STOP-BANG questionnaire and ASA criteria will be done separately for each patient and for each classification method. Patients at high risk will be consulted to the relevant medical department in the preoperative period for further investigation and treatment. In addition, it is aimed to correlate the risk levels determined in the study with postoperative respiratory complications and recovery time.
NCT07484178
The goal of this clinical trial is to evaluate whether respiratory nursing interventions can improve respiratory outcomes in patients hospitalized with acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD). The main questions it aims to answer are: Do respiratory nursing interventions improve dyspnea levels measured by the Modified Medical Research Council (mMRC) Dyspnea Scale? Do these interventions improve oxygen saturation and pulmonary function (FVC, FEV1, and FEV1/FVC ratio)? Researchers will compare patients receiving respiratory nursing interventions plus routine hospital care with patients receiving routine hospital care alone to determine whether the interventions improve respiratory outcomes. Participants will: Undergo baseline assessment using the mMRC Dyspnea Scale, pulse oximetry, and pulmonary function tests. Receive either respiratory nursing interventions (deep breathing exercises, chest percussion, postural drainage, and lukewarm water intake) along with routine care or routine hospital care alone. Be reassessed after the intervention period using the same respiratory outcome measures.
NCT07483723
Polycystic ovary syndrome is a very common condition that is associated with metabolic complications. Patients with polycystic ovary syndrome exhibit insulin resistance and are at greater risk to develop type 2 diabetes. This syndrome is heterogeneous, classified according to 4 phenotypes (A-D). It seems that certain phenotypes are less exposed to insulin resistance and metabolic complications. However, only a few studies have evaluated the glucose profile according to phenotype. New technologies now make it possible to monitor glucose levels continuously. The aim of this project is to evaluate glucose profile parameters using continuous glucose monitoring, and to compare these profiles according to different PCOS phenotypes.
NCT07482033

The study will include two groups, and intergroup differences will be evaluated: 1. Control group 2. Intervention group Study Hypotheses H1: Pecha Kucha-based education on noninvasive mechanical ventilation (NIMV) support provided to individuals with chronic obstructive pulmonary disease (COPD) increases patients' self-efficacy levels. H2: Pecha Kucha-based education on noninvasive mechanical ventilation (NIMV) support provided to individuals with chronic obstructive pulmonary disease (COPD) reduces patients' symptom levels. H3: Pecha Kucha-based education on noninvasive mechanical ventilation (NIMV) support provided to individuals with chronic obstructive pulmonary disease (COPD) improves patients' activities of daily living.
NCT07475351
The purpose of this randomized study is to compare donor site morbidity and clinical and functional outcomes of both surgery techniques (bone-patellar tendon-bone (BPTB) graft versus bone-patellar tendon without patellar bone plug (PT) graft) for anterior cruciate ligament reconstruction (ACLR) in athletes. The main questions it aims to answer are: * Does PT graft reduce donor site morbidity compared to the standard BPTB graft? * Does PT technique provide clinical and functional results comparable to the BPTB technique? Researchers will compare the incidence of complications and clinical and functional outcomes between the BPTB and PT grafts groups. Patients will: * Undergo ACLR surgical intervention using one of the two assigned techniques (BPTB or PT) * Follow a two-year assessment program, including visits at three, eight, 12 and 24 months after surgery.
