NCT07293013
Backgroud: Radiation therapy and concurrent chemoradiotherapy are the main treatment methods for patients with head and neck cancer, which often lead to many severe oral mucositis (OM). It is easy to cause dry mouth and infection, which seriously affects the comfort and quality of life of patients. There are many pharmacological and non-pharmacological mouthwash solutions in clinical practice, the purpose of which is to reduce bacterial accumulation in order to prevent and improve OM. Olive oil has powerful moisturizing, antioxidant and anti-inflammatory properties. There is no research on the use of olive oil in the prevention or treatment of OM. Objective: The purpose of this study was to evaluate the preventive and therapeutic effects of olive oil as a mouthwash solution on OM caused by radiation therapy or concurrent chemoradiotherapy. Methods: The research design of this study is a randomized controlled trial. Patients from a radiation oncology clinic of a regional teaching hospital in southern China were invited to participate in the study by intentional sampling. The study will be followed for 12 weeks and will collect data before and after treatment with olive oil mouthwash or standard care. Assessment tools include demographic characteristics, severity of OM (RTOG and OMAS), degree of dry mouth (XQ and Saxon test), pain severity(VAS), Shortened General Comfort Questionnaire (SGCQ) and head and neck cancer patients quality of life scale (FACT-H\&N). The research data will be statistically analyzed by SPSS 22.0 statistical software, and the statistical significance is defined as the P value less than 0.05 as the significant level. Statistical methods include 1) Descriptive statistics include times, percentages, averages, standard deviations, etc. 2) Inferential statistics: Chi-square test, independent t-test, paired t-test and Logistic regression were used to compare the post-test data between the experimental group and the control group, and to detect the effectiveness of intervention measures and 3) Using generalized estimating equations (GEE) to predict the effect of interventions (repeated measures) on OM severity, dry mouth, body weight, quality of life and comfort scores. Expected outcomes: This study aimed to investigate the efficacy of gargling with olive oil in reducing the incidence of OM, severity of OM, severity of dry mouth, severity of pain, and improved patient comfort and quality of life.
NCT05237505
Major progress has been made in the area of cardiovascular disease, but we believe that further progress will involve mechanistically addressing underlying respiratory causes including chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA). The most common cause of death in COPD is cardiovascular, although mechanisms are unknown. OSA has been associated with major neurocognitive and cardiovascular sequelae, the latter likely a function of autonomic nervous system abnormalities, oxidative stress, inflammation, and other pathways. Recent data suggest that individuals with OVS die preferentially of cardiovascular disease compared to OSA or COPD alone, although mechanisms are again unclear. The combination of OSA and COPD may lead to profound hypoxemia. Individuals with COPD can develop pulmonary hypertension via disturbances in gas exchange and parenchymal injury leading to loss of pulmonary vasculature. OSA has been associated with mild to moderate pulmonary hypertension, but the situation may be worse if combined with parenchymal lung disease. The biological response to sustained hypoxemia has been carefully studied as has the topic of intermittent hypoxemia; however, to our knowledge, very little research has occurred regarding the combination of sustained plus intermittent hypoxia as seen in OVS. For example, we do not really know whether individuals with OVS develop coronary disease, right or left heart failure, dysrhythmias or some combination of abnormalities predisposing them to cardiovascular death. Thus, design of interventional studies is challenging as causal pathways are poorly understood despite our considerable preliminary data addressing these issues. The purpose of this study is to examine vascular mechanisms in individuals with COPD/OSA overlap syndrome (OVS) compared with matched individuals with obstructive sleep apnea (OSA) alone or chronic obstructive pulmonary disease (COPD) alone and to perform a phase II pilot mechanistic clinical trial in OVS to examine the effect size of nocturnal bi-level positive airway pressure (PAP) vs. nocturnal oxygen therapy in cardiovascular outcomes.
NCT02292004
This study will assess the safety and early efficacy of a newly developed device, bridge-enhanced scaffold (MIACH™,) used to repair a torn anterior cruciate ligament (ACL.)

NCT07190456
Kinesiophobia, defined as an excessive and irrational fear of physical movement due to perceived vulnerability to injury, has gained significant attention in clinical and scientific communities. This condition can act as a barrier to physical activity, negatively impacting patients' disability, quality of life, and the implementation of rehabilitation programs. It is particularly prevalent after anterior cruciate ligament reconstruction (ACLR), affecting physical function, return to sport rates, and patient performance. While the Tampa Scale for Kinesiophobia (TSK) is considered a gold standard for assessing kinesiophobia, recent studies have raised concerns about its validity, especially in ACLR patients. The TSK may not adequately capture fear of specific sports activities, which is more common in ACLR patients than a general phobia of movement. Some researchers argue for an assessment approach similar to that used for pain experiences, emphasizing the subjective nature of fear. Based on the specific phobia model, assessing kinesiophobia in the presence of a trigger, such as visualizing or confronting the movement associated with the injury, may be more relevant. This approach is supported by evidence showing that sports situations evoking the greatest fear after ACLR are cutting, jumping, and contact. Further research is needed to investigate alternative methodologies for assessing fear of movement in ACLR patients, considering the prevalence and repercussions of kinesiophobia in this population. The objectives of this study are threefold: * To compare the magnitude of kinesiophobia through the TSK, the subjective feeling of fear when visualising feared movements, and the subjective feeling of fear in anticipation of the feared situation. * Evaluate the impact of focusing on feared activities on motor behavior and Autonomic Nervous System (ANS) markers. * To assess the relation between the three methods of assessing fear of movement and indicators of motor behaviour, ANS activity, fear-avoidance beliefs, anxiety, avoidance behaviour, and physical function.

NCT07269223
This randomized controlled trial aims to evaluate the effect of oral vitamin D3 supplementation on inflammatory biomarkers and disease activity in Pakistani patients with moderate ulcerative colitis. Sixty patients will be randomized to receive either standard treatment alone/Placebo or standard treatment plus vitamin D3 (50,000 IU fortnightly) for 12 weeks. Primary outcomes include changes in blood (CRP, ESR, IL-6) and fecal (calprotectin) inflammatory biomarkers, and disease activity assessed by the partial Mayo score. Secondary outcomes include vitamin D status, dietary intake, and quality of life. The study will provide insights into the immune-modulating and anti-inflammatory role of vitamin D3 as an adjunct therapy in ulcerative colitis.
NCT06805123
Currently, there are no clear guidelines regarding the optimal timing for dietary restart after gastrointestinal endoscopic submucosal dissection (ESD). While several studies have addressed upper gastrointestinal ESD, a meta-analysis reported that early feeding, initiated within one day after the procedure, showed no statistically significant difference in complication rates compared to delayed feeding initiated after two or more days. Moreover, early feeding was associated with shorter hospital stays and higher patient satisfaction. However, to the best of our knowledge, no studies have investigated early feeding in colorectal ESD. On the other hand, in the context of surgical procedures involving the gastrointestinal tract, several studies suggest that early feeding may offer clinical advantages over delayed feeding. The aim of this study is to explore the optimal timing for dietary restart following colorectal ESD. In the early feeding group (\<24 hours), patients begin water intake if no abnormalities are observed during a follow-up examination conducted two hours post-procedure. If no further issues arise after an additional two hours, a liquid diet is initiated. In contrast, the delayed feeding group (\>24 hours) maintains fasting on the day of the procedure and begins a liquid diet the following day. The study will compare the early and delayed feeding groups in terms of post-ESD early complications (e.g., bleeding, perforation, post-coagulation syndrome), length of hospital stay, patient satisfaction, and delayed complications.

NCT05473780
Background : Long-term oxygen therapy is prescribed for patients with severe COPD. The aim of oxygen therapy is to administer oxygen at a concentration level higher than that of ambient air, in order to treat or prevent the symptoms and manifestations of arterial hypoxemia; this therapy can be applied either in an acute situation or as a long-term treatment, in cases of stabilized severe chronic hypoxemia. Currently, pneumologists do not have the possibility, between 2 consultations spaced several months apart, to measure the patient's compliance with the treatment (adherence to oxygen therapy) nor the respect of the prescribed dosage (O2 flow and duration). In addition to the patient's adherence to the treatment, the specialist does not have the possibility to assess the patient's physical activity (walking ...). This observational study is a e-health, prospective, multicenter study conducted in France under the control of pneumologists. The main objective of this study is to evaluate the adherence to oxygen therapy in real life, and its evolution, in COPD patients justifying a long term oxygen therapy in stable state.

NCT04191551
Gastric cancer afflicts 27,000 Americans annually and carries a dismal prognosis. One reason for poor outcomes is late diagnosis, as the majority of gastric cancers in the United States are diagnosed at a relatively advanced stage where curative resection is unlikely. Gastric precursors (such as atrophic gastritis and intestinal metaplasia) are precancerous changes to the stomach mucosa which increases risk for subsequent gastric cancer. The Gastric Precancerous Conditions Study (GAPS) is an observational study of patients at elevated risk for gastric cancer. Investigators seek to recruit patients from endoscopy unit of Stanford Health Care, a large academic network of hospitals and clinics serving Northern California. Investigators will recruit patients who are both symptomatic (e.g. dyspepsia) and asymptomatic (e.g. referred for screening), and individuals both with known precursor lesions (such as intestinal metaplasia) or at high risk for carrying precursor lesions. A component of the study is long-term follow-up of individuals with gastric precursors. This is to understand their risk factors for histologic progression and regression. During both index and subsequent endoscopies, the study team will collect biospecimens (e.g. blood, saliva, gastric tissue).

NCT07227467
Immediate lymphatic reconstruction (ILR) is a novel surgical approach performed at the time of initial lymph node dissection with the goal of preventing lymphedema.(Chang et al. 2020) It involves the identification of lymphatic channels that are transected after lymph node dissection and microsurgical anastomosis of one or more lymphatic channel with a local recipient vein to re-direct upper extremity lymphatic drainage. Although ILR carries significant promise in prevention of lymphedema, there is a lack of high-level evidence supporting its efficacy because it is a novel surgical technique that is only offered at a few centers and not routinely covered by insurance carriers yet. The University of Chicago Comprehensive Cancer Center (UCCCC) is one of the busiest microsurgery centers performing this procedure, and, as a Lymphedema Center of Excellence, is in a unique position to investigate the efficacy of ILR in preventing lymphedema. In addition, the University has access to a world class microbiome research facility and colleagues. To our knowledge, there is no information on the skin microbiome of the axilla in patients undergoing treatment for breast cancer or those at risk for developing lymphedema. Further exploratory studies such as this in a diverse patient population may lead to practice changing research in our approach to lymphedema management and prevention.
