NCT03977480
This study adopts a multicenter, randomized, double-blind, low-medium-high dose group and placebo parallel controlled clinical study design. After screening, patients with active ulcerative colitis who meet the inclusion criteria and do not meet the exclusion criteria will be randomized by 1:1:1:1 to Hemay007 400 mg BID group, 800 mg QD group, 600 mg BID group or placebo group, with proposed 72 cases in each group. After 12 weeks of double-blind inductive treatment period, the patients will enter the Hemay007 open treatment period of 12 weeks when Hemay007 600 mg BID will be used as the medication regimen. All randomized subjects who have received the investigational drug should be subjected to a 4-week observation after the end of treatment.

NCT05845827
Cardiorespiratory fitness (CRF), also known as "exercise capacity", is the capacity of respiratory and circulatory systems to supply oxygen to skeletal muscle during exercise for the generation of energy. Determinants of CRF include lung capacity, capillary density, cardiac output, hemoglobin concentration, and mitochondrial function. The research group studies how CRF is related to fuel utilization, yielding a mechanistic understanding of the association between lower CRF and worsening metabolic health via mitochondrial function. The objective of this study is to measure fuel utilization in response to habitual diet for one week in adolescents and young adults, ages 14-22 years (n=30). Fuel utilization will be estimated by glucose measures using a continuous glucose monitor (CGM). Habitual dietary intake will be collected via a mobile phone application (BiteAI, Inc) that uses artificial intelligence to extract nutrient information from food photographs. Participants will undergo two standard of care (SOC) meal tolerance tests at home - a glucose tolerance test and a Ensure® mixed meal tolerance test. CRF will be estimated by measuring maximum oxygen consumption (VO2 max) during a graded treadmill test. The hypothesis is that a higher VO2 max will be associated with increased fuel utilization, measured by lower glucose response to the SOC meal tolerance tests. The proposed study is described in the following aims: SPECIFIC AIM 1. Test for feasibility of completion of self-report dietary food records, completion of two at home meal tolerance tests that are standard of care for metabolic health screening, and completion of a seven-day continuous glucose monitor. SPECIFIC AIM 2. Identify nutrients and foods that are associated with an elevated glucose response. SPECIFIC AIM 3. Assess the influence of VO2 max on the glucose response to the SOC glucose tolerance test and Ensure® mixed meal tolerance test.
NCT05817123
Main objective of this study is to assess the psychometric characteristics of the Mutuality Scale both in patients with Obstructive Sleep Apnea Syndrome (OSAS) and in their partners-The association between the mutuality score in OSAS patients and their adherence to the use of Continuous Positive Airway Pressure (CPAP) therapy will also be investigated. The results of the study may allow a validation of the Mutuality Score as an instrument for measuring mutuality between OSAS patients and their partners.
NCT02481778
Rationale: Radiation induced cardiac toxicity after treatment for intrathoracic tumours is a clinically relevant problem. So far, no clinical prediction models exist for cardiac toxicity. In particular, the relationship between radiation dose parameters and the risk of cardiac toxicity remains to be determined. Clinical prediction models for cardiac toxicity are difficult to obtain, e.g. due to long latency time. Therefore, objective surrogate markers, for cardiac toxicity such as NT pro BNP and hs-TNT, as obtained during and after treatment may be of great value. Objective: The main objective to find a correlation between the rise in NT pro BNP level and the radiation dose given to the heart.
NCT04271371
Prisoners experience huge health inequalities, and their exceptionally high smoking prevalence (five times the national average) contributes significantly to their high mortality. Since the introduction of smoke-free polices across Her Majesty's Prison and Probation Service (HMPPS) in England and Wales, prisoners are now obliged to abstain from smoking while held in prison. This represents a unique opportunity to promote lifelong cessation in this highly disadvantaged and marginalised group. However, evidence suggests most prisoners intend to resume smoking as soon as possible after release. A systematic review of prison smoke-free polices worldwide concluded that there was a need for new research to identify effective strategies to reduce relapse in these individuals.
NCT04999228
Pediatric Ulcerative Colitis (UC) patients with moderate to severe disease activity at high risk of colectomy. Early use of biologic agents will likely be more effective. But there were no studies identified that compared a strategy of upfront biologic-based therapy versus gradual step-up therapy. In our study, newly diagnosed moderate to severe pediatric UC patients (6-18 years old) will be randomly divided into infliximab (IFX) treatment group (Top down group, TD) and corticosteroids (CS) treatment group (Step-up group, SU). Mucosal healing rate at week 12 will be compared between the two groups. The relapse rates and sustained durations of remission within one year will also be evaluated.
NCT05338723
This study aims to investigate the possible role of rosuvastatin in protection against cardiotoxicity in HER2 positive breast cancer patients receiving doxorubicin sequential with trastuzumab.
NCT05405686
This is a prospective randomized open-label cross-over study. Poor responder patients will undergo two ovarian stimulation cycles. One with recombinant follicle stimulation hormone (FSH), and an other stimulation with recombinant FSH and recombinant luteinizing hormone (LH). In both groups, a freeze-all strategy will be applied and an endometrial biopsy will be taken 7 days after final oocyte maturation trigger. Endometrial gene expression analysis will be performed on both biopsies. After completion of both treatment cycles, a frozen embryo transfer of a single embryo will be performed.
NCT05849415
Studies suggest that chronic exposure to psychological stress can lead to oral health deterioration, alter the immune response, and possibly contribute to increased inflammation, which can impact the physiological healing of periodontal tissues. People with psychophysiological stress disorders tend to acquire unhealthy habits, leading to less self-care, incorrect nutrition, smoking, alcohol consumption, and reduced physical activity. This cross-sectional study aims to evaluate the correlation between periodontal health and psychological stress. Patients between the ages of 35 and 70 will be recruited. Each patient must be visited and a periodontal assessment must be performed, recording the percentage of bleeding on probing and the Periodontal Screening and Recording (PSR). Subsequently, patients will be administered the Sheldon Cohen Perceived Stress Scale (PSS) and the Mindfulness Awareness Attention Scale (MAAS) questionnaires.
NCT06280456
Post-anterior cruciate ligament reconstruction (ACLR) hemarthrosis may result in increased pain thus delaying postoperative rehabilitation, which may eventually lead to arthrofibrosis and a functional deficit. Many antifibrinolytic agents, including tranexamic acid (TXA), have been used in orthopedic surgeries to reduce postoperative bleeding. Moreover, TXA was proved effective to reduced the events of hemarthrosis and increased the post-operative functional outcomes of the patients in several studies. The purpose of this study is to evaluate the efficacy of intra-articular injection of TXA with different drainage clamping time in patients receiving arthroscopic ACLRs. Patients were randomized into four groups. An intra-articular suction drain was placed recorded 24 h postoperatively. Group 1 patients(TXA 4hr group) received the index procedures with a 10 mL intra-articular injection of TXA and following drainage clamped 4 hours. Group 2 patients(TXA 8hr group) received the index procedures with a 10 mL intra-articular injection of TXA and following drainage clamped 8 hours. Clinical evaluations using an IKDC functional score and a Visual Analogue Scale (VAS) pain score were performed during admission, at postoperative day 3 and week 4.
NCT03012581
This is a Phase 2, non-randomised, open-label, multicentric study to investigate the efficacy and safety of nivolumab monotherapy in 6 cohorts of patients with specific rare cancers who have unresectable locally advanced or metastatic disease, which is resistant or refractory to standard therapy, or for which standard therapy does not exist, or is not considered appropriate, and for which no other experimental treatment options are available.
NCT06283095
The study will be conducted to evaluate the outcome of expansion palatoplasty in management of OSAS.
NCT05029557
Individuals who have COPD need a nursing service, which provides qualified and effective professional care, self-care, and supportive care to perform their daily life activities, and improve their quality of life. It is predicted that the Chronic Care-Based Training Program to be implemented and the follow-ups can increase the level of self-efficacy and satisfaction, and raise awareness on the management of the disease in patients. The purpose of the study was to evaluate the effects of the Chronic Care Model based education and telephone follow-up given to patients with COPD on self-efficacy and patient-reported outcomes. Also, the Modified Patient-Reported Outcome Scale for Chronic Obstructive Pulmonary Disease-mCOPD-PRO scale, which will be used in the study, will be adapted into Turkish language and culture, and will be used in the study after its validity and reliability are examined.
NCT05458531
People with inflammatory diseases treated with immune-suppressing medication are recommended to have regular blood-tests to monitor for potential side-effects of this treatment on their blood count, liver and kidneys. However, it is not clear that monitoring is needed as frequently as currently recommended in the long-term, with side-effects being rare after one year of treatment. A study is currently underway to determine the optimal blood-test monitoring strategy which is cost-effective but still safe. Any changes in the monitoring strategy must be acceptable to patients and the healthcare professionals (HCP) that treat them. This study aims to measure how often patients' with common inflammatory conditions on long-term immune suppressing medication attend their monitoring blood tests as currently recommended, and uncover patients' and HCP views and experiences of the current blood-test monitoring strategy, and the acceptability of potential changes to this in the future. Firstly, patients with an inflammatory condition on long-term immune suppressing treatment will be invited to complete a questionnaire which will ask about their demographic information, medical condition(s), immune-suppressing treatment, adherence to the monitoring blood tests and willingness to take part in an interview. Then, both patients and HCPs who care for such patients will be invited to take part in a single, semi-structured interview. Interviews will be face-to-face, by telephone or video-call, last up to one hour and digitally audio-recorded. Patient interviews will explore their perceptions of risk, benefits and experiences of current testing, and views on the new testing frequencies emerging from the study prior. HCP interviews will explore their perceptions of current testing including, the practicalities, usefulness, risks and benefits of the blood tests, and views on the new testing frequencies emerging from the study prior. The findings will shape the recommendations for a new monitoring strategy, ensuring it is acceptable to patients and HCPs.
NCT06279403
Study Objective: To determine the efficacy of upfront immune checkpoint inhibitors combined with deferred cytoreductive nephrectomy in treating metastatic renal cell carcinoma. Primary Endpoint: Pathological Major Response (MPR), defined as the percentage of residual tumor cells \<10% in the primary tumor after nephrectomy. Study Design: Population: Participants meeting the diagnostic criteria with biopsy-proven clear cell renal cell carcinoma, IMDC score ≤3, or ≤5 metastatic lesions involving ≤3 organs. Sample Size: 20 participants. Patient Grouping: Non-randomized. Interventions: Eligible participants will receive upfront treatment with a combination of Axitinib and Toripalimab for 4 cycles. After 2 cycles of treatment, radiological assessment will be conducted using RECIST 1.1 criteria. If disease progression is observed, the clinical trial will be terminated, and second-line treatment will be initiated according to guidelines. If disease progression is not observed, treatment will continue for 2 additional cycles followed by repeat radiological assessment before undergoing surgery.
NCT05509881
This randomized controlled trial will investigate whether use of continuous glucose monitoring (CGM) vs. usual care with self-monitored blood glucose 1) enhances glycemic control, 2) reduces hypoglycemia risk, and 3) improves quality of life, diabetes distress, and fear of hypoglycemia in hemodialysis patients with diabetes mellitus.
NCT06026670
Minimally invasive thoracic surgery is increasingly popular. Recently, a new minimally invasive thoracic approach, robotic-assisted thoracic surgery (RATS) has been developed. RATS presents some advantages compared to VATS such as three-dimensional view of the surgical field, its precisions facilitates the navigation in difficult to access spaces and eliminates tremor which reduces learning curve and it may have a reduction of complications. During RATS and differently from VATS, not only one lung ventilation (OLV) is needed but also a continuous tension capnothorax. CO2 insufflation with intrathoracic positive pressure has a potential negative impact on the cardiorespiratory physiology. Moreover, CO2 insufflation and one lung ventilation can produce ventilation induced lung injury which are related to pulmonary postoperative complications (PPC). In order to reduce PPC and ventilation induced lung injury, lung protective strategies are used which reduce atelectrauma and overdistension. These strategies consist of three main pillars: use of low tidal volumes, performance of recruitment maneuvers and application of optimal positive end-expiratory pressure (PEEP). However, optimal PEEP levels and actual effects of PEEP are not clear. Several clinical studies with one-lung ventilation have reported improved oxygenation and ventilation when an alveolar recruitment maneuver is performed with a standardized PEEP of 5 to 10 cm·H2O. Nevertheless, other studies observe during one-lung ventilation improvements in oxygenation and lung mechanics with individualized PEEP determined by using a PEEP decrement titration trial after an alveolar recruitment maneuver. The effect of a tension capnothorax during RATS may modify pulmonary compliance and optimal PEEP may be different from patients having VATS resection. Even though both methods are habitual in the clinical practice, there are no studies of the effect of an alveolar recruitment maneuver with individualized PEEP during one-lung ventilation in Robotic-Assisted Thoracic Surgery (RATS). The investigators hypothesized that such a procedure would improve oxygenation and lung mechanics during one-lung ventilation in RATS compared with the establishment of a standardized PEEP. The investigators perform a descriptive observational prospective study to test this hypothesis.
NCT04955405
New approaches to care transitions must deploy a longer-term and more intensive program that provide an array of services that address underlying social determinants of health (e.g. lack of adequate social support, lack of self-efficacy in managing symptoms and medications, impoverished living conditions, inability to connect with primary care and access. In addition, programs must be adaptable to meet the specific needs of individual patients. Our collaboration of health services researchers, quantitative scientists, and physicians propose to develop and implement a 90-day intensive and comprehensive intervention to support newly discharged patients with COPD and/or CHF. The proposed intervention will utilize a three-person team (registered nurse, clinical social worker, and a pharmacist) to provide an array of medical and social services specifically targeted to meet the needs of individual patients and their families. Aim: To determine using a randomized control trial, whether participation in an intensive series of 7 home-visits that provide tailored medical and social services among newly discharged low-income Medicare patients with COPD and/or CHF results in a) better patient-reported outcomes and b) a reduced likelihood of repeat hospital care (ED use or hospitalization) relative to a group of patients who receive usual discharge instructions.
NCT02140736
