NCT06306755
To evaluate the feasibility, applicability, effectiveness, and health-economic value of the risk-based sequential screening modality for esophageal and gastric cancers, the investigators aim to initiate a community-based randomized controlled trial in Xun County, Henan Province, which is a high-risk region of upper gastrointestinal cancer (UGIC) in northern China. A total of 258 target villages from all the 11 communities (townships and streets) in Xun County will be randomly selected and assigned to the sequential screening group and the universal screening group at a ratio of 2:1 and the total sample size will be 21,000. In the sequential screening group, participants in the top 50% risk level (i.e., stratified as the high-risk subgroup) will be offered a standard upper gastrointestinal endoscopic screening. In contrast, all participants in the universal screening group will receive the endoscopic examination. The surveillance strategy for participants with screening-detected premalignant lesions in the sequential screening group will be tailored based on individualized risk assessment using endoscopic characteristics, pathological diagnosis, and biomarkers. Surveillance for participants in the universal screening group will adhere to current guidelines for UGIC screening and clinical treatment. Detection rates of upper gastrointestinal malignant lesions, early-stage malignant lesions and premalignant lesions, and health-economic indicators such as the unit cost per detected malignant lesions will be compared between the two groups.

NCT06791915
Radiofrequency ablation (RFA) for atrial fibrillation (AF) is performed under general anesthesia. The success of the procedure depends on the safe contact of the catheter electrode with the myocardium. Movement of the catheter tip due to respiratory changes can result in inadequate lesion formation and AF recurrence. The success of AF ablation depends on the adequacy of energy delivered to the myocardium and the durability of pulmonary vein isolation (PVI). Poor energy delivery and tissue heating during ablation are a major cause of procedural failure in RFA. To improve the success of the PVI procedure, efforts are underway to optimize catheter stability and contact force. However, catheter force and stability are influenced by respiration-induced thoracic motion, highlighting the importance of controlled breathing for further optimization. Fluoroscopy and ablation times during electroanatomic mapping-guided AF ablations improved with controlled mechanical ventilation. General anesthesia improved catheter contact. Low tidal volume, high respiratory rate (FCV), pressure controlled mechanical ventilation (PCV), volume controlled mechanical ventilation (VCV), pressure controlled volume assured mechanical ventilation (PRVC) can be used in investigators' hospital. The literature offers no definitive proof that one ablation procedure is superior to another.

NCT06791369
The skeletal muscle ryanodine receptor (RYR1) gene encodes an important calcium channel in skeletal muscle, with an important role in muscle contraction. Mutations (i.e. disease-causing changes) in RYR1 are associated with an immensely wide range of clinical problems, ranging from inborn muscle conditions with profound weakness at birth ("congenital myopathies"), to a potentially fatal anaesthesia complication ("Malignant Hyperthermia, MH") in otherwise healthy individuals. Although RYR1-related conditions are believed to be amongst the most common neuromuscular disorders, their precise prevalence (i.e. the number of cases in a particular population at a given time) is currently unknown. Moreover, there is no information regarding the relative frequency of specific congenital myopathies, MH and related manifestations, such as the associated bleeding abnormality recently described by our team. The lack of reliable prevalence data represents a major obstacle to addressing the needs of individuals affected by RYR1-related conditions, to appropriate resource allocation, and to preparation for clinical studies ("trial-readiness") essential for therapy development. To address this shortcoming, we will conduct an international collaborative study involving neuromuscular and MH centres from the UK and the Netherlands, focusing on the prevalence of RYR1-related conditions, as a group and per subtype. The countries participating in this study were included because of 1) centralized RYR1 testing, 2) the presence of at least one database/registry with population-wide coverage capturing RYR1-related disorders and 3) of national myopathy and MH expertise centres. Information regarding RYR1-mutated individuals and their specific diagnosis will be obtained from national databases/registries, and analysed utilizing statistical methods that are well-established in the field of epidemiology. This study will provide important information regarding the actual disease burden of RYR1-related disorders on a wider scale, inform appropriate research resource allocation, and preparation for trial readiness. This study will be funded by the RYR1-Foundation.

NCT06790875
The goal of this clinical trial is to learn how low tidal volume ventilation (LTV) and airway pressure release ventilation (APRV) affect lung tissue mechanics in adults with ARDS. The main questions it aims to answer are: Does LTV or APRV improve lung tissue mechanics in patients with ARDS under mechanical ventilation? Researchers will compare LTV and APRV to see which ventilation mode works better for improving lung mechanics and patient safety.
NCT06790901
We know that respiratory functions of patients are affected under general anaesthesia. Although there are many underlying causes of ventilation-perfusion mismatch in the airways, the main cause is atelectasis during general anaesthesia. Atelectasis occurs in almost all patients receiving general anaesthesia. The main cause of atelectasis is the loss of muscle tone during general anaesthesia. Postoperative atelectasis was described in the last century. It is defined as the closure of the alveoli due to a decrease in inspiratory force and collapse of the lung and the resulting loss of aeration. Inhalation anaesthetics have been shown to cause hypoxic pulmonary vasoconstriction in studies. However, not all inhalation anaesthetics affect the airways in the same way. In patients who will undergo surgical procedures under different general anaesthesia maintenance methods, conditions that disrupt the ventilation-perfusion balance in the lung peroperatively can be diagnosed and monitored early, easily and inexpensively by lung ultrasonography. Lung ultrasound is a noninvasive, reliable, reliable, radiation-free imaging method that provides instantaneous imaging at the bedside. Lung ultrasound score is a scoring system that provides scoring of the loss of ventilation in the lung. For this purpose, it was aimed to divide both lung tissues into 12 areas and to give a score between 0 and 3 points and to show the severity of the loss of aeration according to the resulting total score.

What are the age-, sex-, and fitness-specific benchmarks for EI to differentiate between normal and pathological muscle quality?
NCT06791590
Neurogenic dysphagia refers to swallowing disorders caused by the damage of swallowing central or peripheral nerves and muscles. According to statistics, about 50% of patients with neurological diseases will be complicated with neurogenic dysphagia. Common diseases include stroke, dementia, Parkinson's disease and neuromuscular diseases. Dysphagia has a great impact on the quality of life of patients, and is related to malnutrition, aspiration pneumonia and even death. In severe cases, tracheotomy is required to maintain airway patency and discharge secretions. The common nutritional support methods for patients with neurogenic dysphagia after tracheotomy are nasogastric or nasointestinal tube placement and percutaneous gastrostomy. intermittent oro-esophageal tube feeding (IOE) is a new nutrition method proposed by scholars in recent years. Studies have shown that it can improve the swallowing function of patients with dysphagia while meeting the nutritional needs of patients, so as to effectively improve the quality of life of patients. However, there are few studies on patients with dysphagia after tracheotomy. This study aims to compare the intervention effects of two kinds of tube feeding methods in patients with neurogenic dysphagia after tracheotomy.
NCT06790979
In patients with traumatic brain injury, post-traumatic sleep patterns have the potential to impact clinical prognosis. While some progress has been made in the study of sleep and prognosis in patients with traumatic brain injury, there is still lack of research on the relationship between sleep and clinical prognosis in post-traumatic patients due to differences in study design, patient age, severity of trauma, and definitions of sleep disorders. Additionally, the primary data collection methods employed in most studies have been self-reported sleep assessments, which are subject to potential biases and inaccuracies. Therefore, explore the impact of sleep patterns on clinical prognosis in post-traumatic patients, with potential to advance our comprehension of recovery outcomes in this patient group.
