NCT06924645
Existing studies have demonstrated that patients with different types of tumors exhibit significant increases in Enterobacter and Staphylococcus genera, along with marked decreases in Lactobacillus, Bacteroides, Bifidobacterium, and Enterococcus genera in their feces following chemotherapy. Research reports indicate a significant decline in bacterial diversity in rectal cancer patients post-chemotherapy, particularly showing reduced abundances of Porphyromonas, Peptostreptococcus, and Veillonella. Motoori et al. found that esophageal cancer patients undergoing combined chemotherapy with 5-FU, cisplatin, and docetaxel experienced significant reductions in intestinal Lactobacillus, alongside notable increases in Clostridium difficile and Enterococcus. Iida et al. confirmed that gut microbiota enhances the therapeutic efficacy of platinum-based agents and CpG oligonucleotides in cancer treatment. Concurrent studies suggest that probiotic supplementation during chemotherapy alleviates chemotherapy-related gastrointestinal reactions. Fecal microbiota transplantation (FMT), which involves transferring functional microbiota from healthy donors to patients' gastrointestinal tracts to reconstruct gut microbiota and improve microbial homeostasis, has emerged as a key clinical approach for regulating gut dysbiosis. It is currently recognized as the most effective established therapy for recurrent Clostridioides difficile infection (CDI). Previous studies have indicated FMT as a relatively safe, effective, and recommended treatment modality, while providing theoretical and experimental foundations for elucidating its efficacy and safety in preventing/reducing gastrointestinal symptoms associated with digestive tract cancer therapies. This study aims to evaluate the improvement of treatment-related gastrointestinal symptoms and safety profile of FMT in extrapulmonary neuroendocrine tumor patients.
NCT05321927
Persons with multiple sclerosis (pwMS) often have an increased sense of fatigue. Furthermore, they present walking difficulties which negatively affects their mobility and results in an additional increase of fatigue. Previous literature suggests that transcutaneous electrical nerve stimulation (TENS) of leg muscles might increase their walking capacity and decrease perception of fatigue. In the present study we aim to investigate whether TENS of leg muscles reduces walking difficulties and sense of fatigue in pwMS in comparison with a short strength training protocol or no training. A similar aim is addressed after TENS of elbow flexor muscles. Subjects with relapsing remitting or progressive MS, will undergo transcutaneous electrical nerve stimulation (TENS), strength exercises (SExerc), both TENS and SExerc (COMB) simultaneously, or sham stimulation without training (CON) of both leg and arm muscles. Force and fatigue measurements are performed before, directly after and three weeks after the training sessions and contain walking, fatigue, and strength assessments. Main study parameters are changes in the scores of i) the six-minute walking test (6-MWT), ii) the perceived walking disability (MSWS-12) and iii) fatigue questionnaires (FSS and MFIS). Additional study parameters are changes in muscle force and muscle fatigability.
NCT06252142
One of the standard treatment options offered to patients of locally advanced rectal cancer is neoadjuvant (treatment given before surgery) radiotherapy \& chemotherapy followed by surgery. In patients whose tumour has completely reduced after neoadjuvant treatment, the wait and watch strategy is also an option. This is another standard treatment option for patients of locally advanced rectal cancers. In this, the patient is monitored after treatment completion. In this study, investigators are only going to observe the patient's response to treatment, monitor their side-effects due to treatment and assess their quality of life using standardized quality of life questionnaires. No additional tests or hospital visits will be required as a part of this study. The patient will be followed up, as per standard follow-up protocol, for at least 2 years after the completion of their treatment.
NCT06910514
The objetive of this clinical trial is to evaluate the efficacy and safety of a solution for endoscopic mucosal resection of colonic lesions in patients undergoing endoscopic resection procedures. The main questions it aims to answer are: Does the investigational solution improve the efficacy of endoscopic mucosal resection compared to standard practice? Is the investigational solution safe for use in colonic lesion resection procedures? Researchers will compare the investigational solution (Demirex) to a standard or placebo solution to see if it improves procedural outcomes and safety profiles. Participants will undergo endoscopic mucosal resection using either the investigational solution or the comparator, and will be monitored for procedural success, safety, and any adverse events.
NCT05183568
This study will test a psychological intervention for the treatment of distress related to infertility. The intervention will pair reading a book "The Mindful Self-Compassion Workbook" by Kristin Neff with guided meditations using the Centre for Mindfulness Studies mobile app. Individuals with infertility will complete the 8-week program and complete psychological outcome measures before and after.
NCT05351476
Adipose tissue turnover plays a critical role in body weight maintenance, and obesity is underscored by the dysregulated balance between fat breakdown and synthesis. Although there are clear health-related benefits of physical activity, little is known about how resistance exercise, as opposed to endurance exercise, can reduce the risk of metabolic disorders, particularly in women. The goal of the proposed study is to investigate the effectiveness of resistance training to improve basal and stimulated fat metabolism in postmenopausal women with obesity and pre-diabetes, potentially serving as a viable and practical approach to prevent the onset of type 2 diabetes.
NCT06323616
Some changes in the patient's cognitive state are observed during the recovery period from general anesthesia. This period of behavioral dysregulation has been called emergence agitation (EA) and emergence delirium (ED). ED and EA occur in the early postoperative period (often within the first 30 minutes). The incidence of ED ranges from 10% to 80% in children and is described as a distressing clinical condition by 42% of pediatric anesthesiologists. Self-harm by the child increases the risk of delayed discharge and may increase the cost of medical care. Sevoflurane is a widely used agent for the induction and maintenance of anesthesia, but its use is associated with the occurrence of ED in the pediatric population. Clinical findings are characterized by hallucinations, struggling, restlessness, crying, and disorientation. In the literature, the Pediatric Anesthesia Rescue Delirium (PAED) Scale Score is used in the diagnosis of ED and EA. This score consists of 5 criteria (maximum score 20) scored using 0-4 point scales. These criteria; The child needs to make eye contact with the caregiver, the child's movements are purposeful, the child is aware of the environment, the child is restless/angry, the child cannot be consoled. While the sensitivity of ≥10 points for the diagnosis of ED is 64% and the specificity is 86%, the sensitivity of \>12 points for the diagnosis of ED is 100% and the specificity is 94.5%. Monitoring intraoperative depth of anesthesia in the adult population has been recommended by the American Society of Anesthesiologists (ASA) due to its potential benefits such as faster recovery time and lower drug dosage, as well as prevention of adverse effects such as the incidence of hypotension. The use of anesthesia depth monitors used so far for children is controversial because brain development in children has not yet been completed and the calculation algorithms of these indices are based on adult EEG characteristics. There are very few studies in the literature on the relationship between anesthesia depth monitoring and EA/ED in children, and further studies are needed.

NCT06502743
The goal of this study is listed below. Part A (Safety Run-in Phase) : To determine feasibility of pembrolizumab and nesuparib combination as maintenance therapy in patients with MMR-proficient advanced and recurrent endometrial cancer. Feasibility is defined as a dose-limiting toxicity (DLT) rate less than or equal to 33%. Part B (Randomization Phase) : To evaluate the efficacy of pembrolizumab and nesuparib combination/ pembrolizumab monotherapy as maintenance therapy in patients with MMR-proficient advanced stage and recurrent endometrial cancer. Efficacy will be assessed by investigator assessed progression free survival (PFS) as assessed by RECIST 1.1.
NCT06907420
In schizophrenia, an abnormal reduction in neuronal gamma oscillations (30-100 Hz) is associated with negative symptoms such as cognitive dysfunction. The literature suggests that rescuing gamma oscillations through non-invasive brain stimulation may be an accessible and safe add-on strategy to mitigate negative symptoms. Here, a stimulation protocol based on gamma visual stimulation will be tested. This pilot study will follow an uncontrolled clinical trial design: A minimum of ten patients diagnosed with schizophrenia or a schizoaffective disorder and predominant negative symptoms will be recruited at Klinikum rechts der Isar. They will undergo a multisession stimulation protocol, consisting of one hour of 40 Hz visual stimulation per day over five consecutive days, during which they will be encouraged to fall asleep. An equal number of patients will be recruited for a treatment-as-usual group without intervention. Pre- and post-assessments will include EEG, a cognitive test battery (THINC-IT), a mood scale (PANAS), and a schizophrenia symptom scale (PANSS). This study's results will inform on the feasibility of gamma visual stimulation as a potential add-on intervention in schizophrenia.
NCT03894618
This is a Phase 1 first in human, open label, multi-center, dose escalation and dose expansion study to evaluate the safety, tolerability, PK, anti-tumor activity and pharmacodynamic effects of SL-279252 in subjects with advanced solid tumors or lymphomas.
NCT06905639
Study Type: Clinical Trial Primary Purpose: To determine whether physical exercise improves or prevents lymphedema in breast cancer patients. Description of the Participant Population/Main Condition: The study is aimed at women who have been diagnosed with breast cancer and have experienced post-treatment lymphedema or are at risk of developing it. The target population includes adults aged 18 to 70 who have been diagnosed with this condition following their breast cancer treatment. Main Research Questions: Does physical exercise improve or prevent lymphedema in women with breast cancer? What are the effects of physical exercise on the reduction of arm volume affected by lymphedema? What are the effects of physical exercise on the reduction of perceived disability in the arm affected by lymphedema? Hypothesis: Physical exercise intervention significantly reduces lymphedema symptoms, such as arm volume. Physical exercise prevents the progression of lymphedema in women with breast cancer. Comparison Group: Researchers will compare results between the experimental group (which will undergo physical exercise) and the control group (which will receive no intervention) to determine if physical exercise has a significant impact on the improvement or prevention of lymphedema. Participant Tasks: The experimental group will follow a supervised physical exercise program for a specific period. The control group will receive no intervention and will be monitored with standard follow-up care without exercise. Participants will be evaluated before and after the study period to measure the progression of lymphedema, including arm volume measurement and surface skin temperature using thermography.
NCT05932810
The purpose of this research study is to evaluate a mobile application (app) for depression treatment called "Moodivate" among cancer survivors. Moodivate was developed by the investigators to assist with the treatment of depressed mood. Participants will be randomly assigned to either download the mobile app, "Moodivate", or not. Approximately 2/3 of participants enrolled will receive the mobile app and the remaining 1/3 will not. All participants will complete electronic questionnaire measures throughout the study period. Questionnaires will assess symptoms of depression, as well as the participant's experiences using Moodivate and participating in this trial. Participation in this study will take about 4 weeks, beginning today. Participation in this study may help in the treatment of future cancer survivors. The greatest risks of this study include frustration, worsening of emotional distress, data breach, and/or loss of confidentiality. Alternative treatments include the participant contacting their primary care provider or their oncology care team to discuss other available treatments for depressed mood.
NCT06099301
In Hong Kong, the shortage of mental health professionals has been a public health concern for many decades. The World Health Organization (WHO) recommends self-care intervention as one of the most promising and exciting new approaches to improve health and well-being. Rapid development in digital technologies is making population-based self-care interventions possible. The goal of this pilot randomised controlled trial is to provide brief advice of a list of mental health mobile apps for reducing depressive symptoms and anxiety in adults. Participants will be instructed to use four mobile apps for 10 min each day for 30 days. They have freedom to choose which one app to use, or a mix of two or three apps. The Waitlist control group will not receive treatment from the research team during the assessment period. But they will be notified their evaluation results (mild to moderate depression) after they complete the baseline assessment. They will receive the information about mental health hotline services for general public. The hypothesis is that the interventions show preliminary effectiveness in reducing adults' depressive and/or anxiety symptoms.
NCT06536439
A proposed new tool ('DIPLANN-tool' - Digital Planning in Nephrectomy) for predicting kidney perfusion zones on a segmented 3D model during robot-assisted partial nephrectomy (RAPN) for localized renal cancer demonstrated high accuracy when planning selective clamping (SC) for RAPN. However, the tool's clinical added value still needs to be confirmed. Therefore, a randomized controlled trial using a study and control group is the preferred study design. Experimental group: the use of the DIPLANN-tool + conventional computed tomography (CT) imaging for preoperative planning and perioperative guidance during RAPN. Control group: the use of only conventional CT imaging for preoperative planning and perioperative guidance during RAPN (= current standard of care). The primary endpoint is planning and performing as planned a SC strategy. Secondary endpoints include patients' health, patients' insight and surgeons' benefits.
NCT03573791
Neoadjuvant therapy has been widely applied to locally advanced rectal cancer. However, about 50% of patients receiving this therapy do not respond well as evidenced by the fact that their T or N stages are not effectively decreased judged by postoperative pathological examination. The purpose of this trail is to identify the biomarkers (from within patients' tumor mass before neoadjuvant therapy) to predict resistance to neoadjuvant therapy. These biomarkers can help stratify neoadjuvant-resistant patients towards surgery while avoiding unnecessary chemoradio-based neoadjuvant therapy.
NCT04098068
