Filter by:This is a prospective, randomized, two-arm, controlled 30-day investigational pilot trial using the gammaCore Sapphire S non-invasive vagus nerve stimulation (nVNS) device + standard of care (SOC) in newly-hospitalized patients with mild-to-moderate traumatic brain injury (TBI) to prevent the progression towards immunokine storms, systemic inflammatory response syndrome (SIRS), severe respiratory distress, and requirement for invasive mechanical ventilation, and death, when compared to SOC alone (the control arm).
This study is a randomized, double-blinded, controlled design. In this study, low doses of S-ketamine were selected for surgury treatment in septic patients under general anesthesia , Meanwhile, activity of HO-1 protein , oxidative stress and inflammatory markers in serum are measured to evaluating the effects of S-ketamine Anesthetic on inflammatory response in septic patients undergoing abdominal surgury. In addition,It is very necessary to make use of the advantages of low-dose S-ketamine in anti-inflammation, and avoid the side effects of mental symptoms, so as to guide the new direction of perioperative clinical application of S-ketamine.
Objective of the study is to assess the safety and efficacy of CO2 removal by the multiECCO2R (CO2 Removal System) on the multiFiltrate/multiFiltrate Pro in veno-venous extracorporeal circulation during continuous renal replacement therapy (CRRT) in patients presenting with hypercapnia due to acute lung failure and acute kidney injury.
The purpose of the study is to assess whether lung ultrasound is able to detect lung injury after lung resection surgery.
Profile known and novel biomarkers in blood in COVID19 patients to characterize the host response to SARS-CoV-2 over time and in response to treatment. The investigators aim to: - Better understand the disease. The investigators will achieve this by characterizing the biology of COVID-19 infection and the pathophysiology of the host response using clinical data together with cellular and molecular measurements over the course of the disease. This will allow better insights for the discovery and development of novel therapeutics. - Understand why different patients have different phenotypes and disease presentations over time. The investigators will achieve this by analyzing for patient subgroups. This will allow targeted patient stratification and better matching of resources. - Understand how patients are responding to the different medications being tested in clinical trials. The investigators will achieve that by co-enrolling with therapeutic trials. This will allow an understanding of the biological effects of these interventions. Study Design: Observational adaptive study of a translational nature, combining clinical data and basic science investigations in blood samples in the same patients, longitudinally, with serial interim analyses. Primary outcomes: 90 day ICU mortality. Secondary outcomes: measures of ICU utilization and disease severity, and 90 day in-hospital mortality. The study ends after 3 months from admission to the ICU, hospital discharge or death. Location: St. Michael's Hospital (Unity Health Toronto), an academic center in downtown Toronto affiliated with the University of Toronto. The investigators will collect: A) Detailed clinical data including investigations, mechanical ventilation and cardiovascular parameters. B) Blood samples for state-of-the-art multi-omics biomarker discovery and development: cytokines, anti-COVID19 antibodies, autoimmune serology, metabolomics, transcriptomics, epigenomics, deep immune phenotyping, viral loads. For those patients who die with COVID19 The investigators will perform bedside post-mortem biopsies of lung, heart, kidney and muscle. Sampling times: From admission to the maximal severity phase through convalescence, in order to capture the evolution and dynamics of the disease and the recovery process: days 0,1, 3, 5, 7, 10, 15 and 22, and then every 2 weeks until the end of the study (3 months from admission to the ICU, hospital discharge or death).
Improving the anesthesiology management for surgical correction of spinal deformations with introducing the diagnostic methods and treatment strategy of acute pain, preventing the evolution of chronic pain. Development and implementation in clinical practice perioperative intensive care protocols for surgical correction of spinal deformities.
The treatment of patients with major burns requires resuscitation with massive amounts of fluid, typically a type of salt water that is given by vein. This frequently results in injury to vital organs, especially the lungs and kidneys, and even in death. In this study, the investigators propose to use plasma, a specially prepared blood product made from the liquid part of blood, that has undergone special treatment to reduce the risk of disease transmission. The aims include 1) reduce the amount of fluid given during the first 24 hours after a burn 2) reduce the incidence of lung injury and other complications related to the administration of funds and 3) determine if the blood product has any effect on inflammation. An overall decrease the amount of fluids that burn patients receive should decrease the potential for lung injury, decrease days in the hospital, and improve survival.
The purpose of the study is to assess whether lung ultrasound is able to detect lung injury after lung resection surgery.
Sepsis is the most frequent risk factor for ALI/ARDS. Meanwhile, Pulmonary is the most vulnerable organ to fail in response to sepsis, vascular endothelial dysfunction is a central event in the pathophysiology of sepsis. An improved understanding of endothelial response and associated biomarkers may lead to strategies to more accurately predict outcome and develop novel endothelium-directed therapies in sepsis. The human and mouse R-spondins encode a family of proteins that includes four paralogs (R-spo1-4). R-spondins are secreted proteins found primarily in the extracellular region and are known to promote β-catenin signaling. Among them, the embryonic lethal vascular remodeling phenotype of R-spondin3 (Rspo3) mutant mice suggests a role of EC derived Rspo3 in angiogenesis. Rspo3 protects tissues against mesenteric I/R by tightening endothelial cell junction and improving vascular intergrity. However, the role of Rspo3 in sepsis-induced pulmonary endothelial dysfunction remains unclear. Thus, it is worthwhile to explore the relationship between Rspo3 and sepsis-induced lung injury, which will be helpful for prevention and treatment of sepsis-induced lung injury and endothelial dysfunction.
Introduction: Sepsis-induced acute respiratory distress syndrome(SI-ARDS) is a common complication of severe sepsis and is an independent contributor to poor prognosis of patients. It remains a clinical challenge to identify the SI-ARDS early and accurately, which could optimize the treatment strategy and reduce the mortality risk. Radiomics high-dimensional features extracted from CT images offer an insight into microvascular damage of SI-ARDS that are imperceptible to human eyes and aspects of intra-alveolar heterogeneity with potential prognostic relevance. Methods: Study design Investigators screened all patients with sepsis and septic shock who are treated in Sun Yat-sen Memorial Hospital, Sun Yat-sen University during the period from 1 May 2015 and 30 May 2022. Patients were recruited retrospectively from May 2015 to April 2021 as discovering group, and prospectively during the period from May 2021 to May 2022 as validation group. Follow-up will conducted until April 2023. Cohort descriptions and definitions Investigators plan to recruit 160 patients in discovering group, 40 patients in internal validation group, and 100 patients in external validation group. Patients between 18 and 80 years of age with sepsis and septic shock will be screened for eligibility. SI-ARDS is defined by sequential occurrence of the sepsis-3 consensus criteria for sepsis and the Berlin Definition for ARDS. The exclusion criteria are： 1. admission stay <24hours, 2. the presence of end-stage lung disease or long-term oxygen therapy, 3. critically ill patients who have started mechanical ventilation caused by SI-ARDS before admission, 4. a history of lung transplantation and chronic obstructive pulmonary disease, 5. cancer patients not/have received chemotherapy. Outcome measures In this study, the primary outcome measure was the occurrence rates of acute respiratory distress syndrome(ARDS). It refers to the occurrence of sepsis patients progressed into ARDS. Secondary outcome measures were as follows: 1.28-day mortality 2.ventilator-free days 3.respiratory failure-free days Data collection All clinical data were collected by investigators and trained personnel. Each participant's data will be filled in electronic case report forms (CRF) and store online using REDCap (Research Electronic Data Capture). Discussion: SI-ARDS is one common severe complication with critically ill sepsis patients, which causes high mortality and poor prognosis. Early ARDS patient(arterial oxygen tension/inspired oxygen fraction [PaO2/FIO2] ≤ 300 mmHg but > 200 mmHg) may not require invasive mechanical ventilation, and is more readily reversible than acute respiratory distress syndrome(ARDS). In this ambispecive cohort study, investigators developed and validated novel nomograms incorporating the radiomics signature and clinical signature to provide an easy-to-use and individualized prediction of SI-ARDS occurrence and severe degree in patients with early stage.
