Filter by:The purpose of this study is to test the effects of leg exercise assistive paddling (LEAP) therapy during prolonged sitting (PS) on vascular and functional performance in those with peripheral artery disease (PAD) and age-matched controls. LEAP therapy is a novel application of passive limb movement to enhance blood flow through the legs without muscular contractions. Specifically, LEAP therapy is the rotational passive movement of the lower leg about the knee from 90 to 180 degrees of rotation at a cadence of 1Hz. Previous literature has indicated that this movement pattern can produce robust increases in blood flow in the passively moved limb in healthy individuals, and passive limb movement may protect vascular function during PS. However, the impact of LEAP therapy to improve blood flow in the legs of those with PAD during PS is unknown. To be eligible for this study, those with PAD must be between the ages of 50-85 years, women must be postmenopausal, must have a history of exercise-limiting claudication, have an ankle brachial index (ABI) 0.9. Participants will participate in a randomized cross-over design study with 2 visits (LEAP therapy and no LEAP therapy). For the first visit, participants will be randomly allocated to receive LEAP therapy during 2.5 hours of PS or not. For the second visit, participants will sit for 2.5 hours and will receive the condition that they did not previously receive. Before and after PS, the following measurements will be made: flow-mediated dilation of the popliteal and brachial arteries, arterial stiffness with tonometry techniques, microvascular vasodilatory capacity and skeletal muscle metabolic rate with near-infrared spectroscopy, autonomic nervous system function, and there will be blood drawn from the antecubital vein. After PS, participants will participate in a graded exercise test to assess functional walking capacity. Finally, during PS, near-infrared spectroscopy on the calf muscles and electrocardiogram will be collected continuously to monitor muscle oxygen availability and autonomic activity, respectively. There will be no follow-up.
The goal of this Phase 3 clinical trial is to compare the efficacy of niraparib versus temozolomide (TMZ) in adult participants with newly-diagnosed, MGMT unmethylated glioblastoma multiforme (GBM). The main questions it aims to answer are: Does niraparib improve progression-free survival (PFS) compared to TMZ? Does niraparib improve overall survival (OS) compared to TMZ? Participants will be randomly assigned to one of two treatment arms: niraparib or TMZ. - study drug (Niraparib) or - comparator drug (Temozolomide - which is the standard approved treatment for MGMT unmethylated glioblastoma). The study medication will be taken daily while receiving standard of care radiation therapy (RT) for 6-7 weeks. Participants may continue to take the niraparib or TMZ adjuvantly as long as the cancer does not get worse or completion of 6 cycles of treatment (TMZ). A total of 450 participants will be enrolled in the study. Participants' tasks will include: - Complete study visits as scheduled - Complete a diary to record study medication
This study will be conducted to determine the preliminary efficacy of axatilimab in combination with ruxolitinib and to assess the contribution of axatilimab to the combination treatment effect in participants with cGVHD.
This is a phase 1，randomized, double-blind, placebo-controlled, SAD study to evaluate the safety, tolerability and pharmacokinetics of oral LPM526000133 Fumarate Capsules (LY03017) in healthy adult subjects.
This is a prospective, non-interventional, multicenter, registry of patients with pulmonary associated with interstitial lung disease (PH-ILD).
The objective of this pilot study is to establish evidence to support the validity of HT in improving skeletal muscle function and physical capacity of patients with HFpEF. Our central hypothesis is that HT treatment will lead to improvements in skeletal muscle and microvascular function compared to a control intervention. As a result, we anticipate that patients treated with HT will demonstrate improved skeletal muscle microvascular blood flow and oxygenation resulting in enhanced exercise tolerance. To explore this hypothesis, we propose the following specific aim: Explore the effects of home-based HT on exercise tolerance in patients with HFpEF.
Glucagon-like-peptide-1 is a hormone released by the gut enteroendocrine cells. Its secretion occurs after each meal to enable production of insulin and inhibits the production of glucagon to lower after meal glycemia. It also inhibits gastric emptying and food intake. GLP-1 RA plays a role on GLP-1 receptors present on islet beta cells and delta cells of the pancreas to control insulin. GLP-1 receptors are also present in multiple region of the central nervous system such as the hypothalamus and hindbrain where it results in reducing food intake. For anesthesiologist it is important to understand how GLP-1 RA influence gastric emptying. Indeed, respecting a fasting period (6 hours for solid and 2 hours for liquid) before each surgery is one of the cornerstones of anesthesiology to significantly reduce the risk of pulmonary aspiration. One of the side effects of GLP-1 RA is slowing gastric emptying and increasing the risk of regurgitation in patient that observed a recommended fasting period. During 2023 a lot of cases reports have emerged of pulmonary aspiration or the presence of a full stomach in patient treated by GLP-1 RA for a type 2 diabetes. Despite recommendations made by the American Society of Anesthesiology, it is still unkown what is the best fasting period and how long patients should pause a long acting GLP-1 RA before surgery. In this observational study, we would like to determine the effect of GLP-1 RA on gastric emptying in patient scheduled for general anesthesia. We will measure and compare residual gastric content with gastric ultrasonography in patients treated by GLP-1 RA and in those who are not. We will also do these comparisons in a group of patients with type 2 diabetes treated by weekly GLP-1 RA at different days after the injection of the medication. Our hypothesis is that we will observe a reduction in gastric residue in patients who stopped weekly GLP-1 RA 7 days prior the examination compared to those who have stopped less days considering the same fasting period. This would lead us to propose an optimal duration of stopping time for GLP-1 inhibitors in the preoperative period.
Abstract Objective: This study aims to investigate the potential clinical impact of neoadjuvant immunotherapy in resectable esophageal squamous cell carcinoma (ESCC). The efficacy and safety of combining the programmed death 1 (PD-1) inhibitor serplulimab with nab-paclitaxel and cisplatin as neoadjuvant therapy in patients with resectable ESCC will be evaluated. Methods and analysis: A prospective, single-center, open-label cohort study will enroll 80 patients, with 40 patients allocated to the experimental group and 40 patients to the control group. Patients in the experimental arm will undergo 3 cycles of neoadjuvant therapy comprising serplulimab, cisplatin, and nab-paclitaxel, while those in the control arm will receive 3 cycles of neoadjuvant therapy with cisplatin and nab-paclitaxel. The primary efficacy endpoint will be the assessment of pathological complete response (pCR) following neoadjuvant therapy. Secondary efficacy endpoints will include major pathological response (MPR), disease-free survival, objective response rate (ORR), and monitoring of adverse events (AEs). Ethics: Ethics approval has been obtained from the Ethics Committee at the First Affiliated Hospital (Xijing Hospital) of Air force Military Medical University (KY20242052-C-1).
In the United States, around 19% of reproductive-aged couples suffer from infertility. The psychological distress associated with infertility is well-established; those diagnosed commonly experience depression and anxiety symptoms, diminished quality of life, and relationship dissatisfaction. In the current study, the investigators report on a case series, in which up to 10 infertility patients will receive 12 sessions of Acceptance and Commitment Therapy (ACT). The overarching goal for the current case series is to determine whether ACT might be well-suited for infertility patients experiencing distress. The specific aims are: 1) to describe the components of the intervention that was delivered; 2) to determine the extent to which infertility patients perceive a 12-session ACT intervention beneficial and acceptable; 3) to describe change in mood, stress, and ACT processes across 12 sessions of ACT; and 4) to highlight potential processes through which ACT might promote benefits to the patient by describing how change in mood, stress, and ACT processes relate to each other over the course of 12 sessions of ACT.
