Clinical trials

This study will examine whether patients' ability to perform everyday physical activities before lung surgery is related to their risk of developing lung complications after surgery. It will include adults scheduled for surgery to remove part or all of a lung. The main questions are: * Is lower physical function before surgery associated with a higher risk of lung complications afterward? * Can information reported by patients improve risk assessment when added to routine clinical information? * How is physical function before surgery related to recovery afterward? Participants will complete questionnaires about their physical abilities, breathing symptoms, and recovery. Researchers will also collect information from medical records, including lung function tests, anesthesia care, the type of surgery, pain management, and chest drainage. Participants will be followed after surgery to record lung complications and recovery. This is an observational study. The research team will not assign patients to particular treatments or change their usual surgical or anesthesia care. The findings may help identify patients who need closer assessment and additional support around the time of lung surgery.

This study will examine how pain changes over the first six months after lung surgery and how it affects daily life. It will include adults scheduled for surgery to remove part or all of a lung. The main questions are: * How does pain change from the early days after surgery to three and six months afterward? * Which factors before surgery and during early recovery are associated with persistent pain? * How does pain affect walking, coughing, sleep, mood, and everyday activities? Participants will complete questionnaires before surgery, during their hospital stay, at discharge, and at three and six months after surgery. These questionnaires will assess pain, its effects on daily life, sleep, and emotional well-being. Follow-up after discharge will be conducted by telephone or electronic questionnaires. Researchers will also collect information from medical records about the type of surgery, surgical incisions, anesthesia, pain relief treatments, and chest drains. This is an observational study. The research team will not assign pain treatments or change usual care. The findings may help identify patients who need additional pain assessment and support during recovery.

This study will examine how symptoms and physical abilities change during lung cancer treatment given before planned surgery, and how these changes relate to recovery after surgery. Treatment given before surgery is called neoadjuvant therapy. The main questions are: * How do symptoms and the ability to perform everyday activities change during treatment and before surgery? * Are symptoms and reduced physical function before surgery associated with lung complications or slower recovery afterward? * Can patient-reported information add useful information to routine preoperative assessment? Participants will complete questionnaires before starting neoadjuvant therapy, during treatment, before surgery, and during recovery after surgery. The questionnaires will assess symptoms such as fatigue, breathlessness, and pain, along with physical abilities and well-being. Researchers will also collect information from medical records about cancer treatment, lung function, anesthesia, surgery, pain management, and postoperative complications. Changes to the planned treatment pathway, including delays or cancellation of surgery, will be recorded. This is an observational study. Cancer treatment, surgery, and anesthesia will be determined by the treating clinical teams, not assigned by the research team. The findings may help identify patients who need additional assessment and support before and after lung surgery.

The goal of this clinical trial is to investigate the mechanisms and predictive factors of motor cortex stimulation (MCS) for treating post-stroke thalamic pain, a challenging central neuropathic pain condition. Approximately 25% of patients show no short-term response to MCS, and about 20% experience long-term efficacy decay, yet the underlying analgesic mechanisms remain unclear and objective predictive biomarkers are lacking. This study aims to answer the following main questions: How does MCS modulate thalamic pain through the coordinated interaction of structural connectivity, functional network dynamics, and metabolic balance in the brain? What are the distinct neuroimaging characteristics that differentiate short-term non-responders, long-term responders, and those with long-term efficacy decay? Which multimodal imaging biomarkers can reliably predict short-term and long-term MCS efficacy? Participants will undergo a two-stage MCS surgical procedure. In stage I, epidural electrodes are implanted over the motor cortex, followed by a 2-week external trial stimulation. Participants who achieve a ≥50% reduction in Visual Analog Scale (VAS) pain score will proceed to stage II, receiving an implanted pulse generator for long-term stimulation. Those who do not respond in the short term will have the electrodes removed without undergoing stage II implantation. All participants will complete baseline clinical assessments and multimodal MRI scans (including T1, DTI, resting-state fMRI, and MRS) before surgery. Participants who receive the permanent implant will undergo follow-up clinical evaluations and repeat MRI scans at 3 and 6 months post-surgery. Researchers will compare imaging features across three outcome groups-short-term non-responders, long-term responders, and long-term decay group-to identify predictive biomarkers. Multimodal imaging data will be integrated using LASSO regression to build prediction models for both short-term screening and long-term efficacy warning. This research is expected to establish a "mechanism exploration - efficacy prediction - clinical decision" paradigm, providing objective imaging-based evidence to guide patient selection and postoperative management for MCS treatment.

This prospective, single-center, randomized controlled trial aims to evaluate the efficacy of an intraoperative "Individualized Open Lung Ventilation" strategy compared to a standard lung-protective ventilation strategy in patients undergoing thoracic surgery. One-lung ventilation (OLV) is essential for thoracic surgery but can cause lung injury. While standard care often uses fixed ventilation parameters, this study investigates whether personalizing Positive End-Expiratory Pressure (PEEP) to achieve the lowest driving pressure can reduce the incidence of postoperative pulmonary complications (PPCs) within 7 days after surgery.

This randomized controlled trial evaluates the efficacy of a proactive Goal-Directed Temperature Management (GDTM) protocol in reducing postoperative delirium among patients undergoing Cytoreductive Surgery (CRS) with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for pseudomyxoma peritonei. CRS-HIPEC presents a unique physiological challenge characterized by a biphasic thermal trajectory: potential hypothermia during extensive surgery followed by rapid iatrogenic hyperthermia during perfusion. This study compares a standardized GDTM strategy-which incorporates strict normothermia maintenance and anticipatory pre-cooling prior to perfusion-against standard reactive thermal management. The primary objective is to determine if optimized thermoregulation can attenuate thermal variability and improve early neurocognitive recovery.
