Filter by:The optimal interval between neoadjuvant chemradiotherapy and esophagectomy is still a question that needs to be explored for patients with esophageal squamous cell carcinoma. In this study, based on previous studies, the investigators divided patients into two groups with a cutoff value of 50 days. By comparing the overall survival and disease-free survival of the entire population and non PCR population, the investigators ultimately obtained the optimal surgical timing suitable for clinical use
For this study, cardiac MRI examinations performed will be prospectively included and realized either fully automatically or by a specialized radiology technician. The duration of the automated examinations will be compared to the duration of the manual examinations. The number of failed sequences in both study arms (automated and manual) will be recorded and the quality of the cardiac planes will be compared.
The trial aimed to evaluate the sealant retention, patient's preference and chair time needed during pit and fissure sealant placement under two isolation techniques [Dryshield system (DS) and cotton roll isolation (CRI)] in a university setting.
This study will assess the feasibility of delivering a 12-week time-restricted eating intervention as well as the intervention's preliminary efficacy on persistent cancer-related fatigue among cancer survivors compared to a general health education control. Participants will be randomized 1:1 to one of two arms: time-restricted eating or control. Those in the intervention arm will self-select a 10-hour eating window in which to consume all food and beverages (water is allowed any time, black coffee and unsweetened tea are allowed in the morning). Both groups will receive weekly educational tips on healthy lifestyle behaviors in cancer survivorship. This study will also explore relationships between fatigue, circadian rhythm, and glucose metabolism. The hypothesis is that recruitment will be feasible, and participants will adhere to time-restricted eating and complete study activities over the course of the 12 weeks. The second hypothesis is that time-restricted eating will lead to less fatigue at 12 weeks compared to the control, accounting for baseline fatigue levels.
This study aims to explore whether there is difference in the incidence rate and incidence rate of HCC in patients with chronic hepatitis B who are screened for high risk of liver cancer. Whether the timely intervention can be used to reduce the incidence of HCC for the early screening and early warning patients can provide evidence-based medical evidence for the selection or adjustment of anti HBV drugs in high-risk patients with liver cancer. To provide evidence for whether patients with liver nodules at high risk of liver cancer need to deal with liver nodules in advance.
Dexamethasone has been tested as an effective adjuvant to prolong the effect of local anesthetics for peripheral nerve blocks, both perineurally and intravenously. The purpose of this study is to investigate the effect of the addition of dexamethasone (5mg) at different time to a standard ropivacaine solution (0.5%) on analgesic duration of interscalene block.
Hyperbaric oxygen therapy (HBO2) is recommended for symptomatic patients within 24 h of carbon monoxide (CO) poisoning. However, previous major studies found significantly better outcomes with HBO2 in patients treated within 6 h. Currently, there is no consensus on a CO poisoning-to-HBO2 interval that would not be beneficial. Therefore, the investigators aimed to evaluate the difference in therapeutic effect depending on the poisoning-to-HBO2 interval after CO exposure in patients with acute CO poisoning who received HBO2 within 24 h. The investigators compared the neurocognitive outcomes of patients according to HBO2 time intervals based on the outcomes of patients treated within 6 h (control group) with propensity score matching using the CO poisoning registry of our hospital.
The thrombectomy is an emergency care provided as soon as possible to selected patients suffering from ischemic strokes. Many steps are necessary to prepare this specialized procedure of interventional neuroradiology, including installation and preparation of the patient for this act. This first and essential time required the intervention of many health professionals. The approach consists of a series of formation through in situ simulations for these health professionals, in order to improve and optimize this first step of the procedure (from the installation of the patient to the percutaneous punch by the neuroradiologist).
The goals of this study are to determine if 1) placement times of pit and fissure sealants using the DryShield system differ from those when using the cotton roll isolation technique; and 2) there is a significant difference in patient preference between Dryshield and the cotton roll technique.
Study of time usage of anesthesia team inside the main operating room compares between 2 groups of - Performing regional anesthesia inside the operating room - Performing regional anesthesia in the block room Study purpose: How much will the investigators save time in the main operating room if we perform the regional anesthesia in the block room?
