Filter by:The goal of this prospective observational study is to develop and utilize an Artificial Intelligence (AI) model for the prediction of postoperative sepsis in patients undergoing abdominal surgery. The main questions it aims to answer are: 1. Can a remote AI-driven monitoring system accurately predict sepsis risk in postoperative patients? 2. How effectively can this system integrate and analyze multimodal data for early sepsis detection in the surgical ward? Participants are equipped with non-invasive PPG-based wearable devices to continuously monitor vital signs and collect high-quality clinical data. This data, along with demographic and laboratory information from the Electronic Health Record (EHR) of the hospital, are used for AI model development and validation.
GEODESIC is a prospective descriptive cohort investigation that will examine the generalizability of the novel host gene expression biomarkers, SeptiCyteTM LAB, SeptiCyteTM VIRUS, SeptiCyteTM BACT, and SeptiCyteTM TRIAGE (collectively 18 genes or SeptiCyteTM LVBT) and SeptiCyteTM RAPID, for differentiating children with bacterial sepsis, versus severe viral illness, versus non-infectious related systemic inflammatory response syndrome.
The previous research of our research group shows that during the course of sepsis, the pyroptosis mediated by the caspase-4/GSDMD pathway in immune cells, induced by pathogens, is the main cause of immune collapse in sepsis patients. The preliminary study of this project further reveals that sepsis combined with intrahepatic cholestasis subsequently induces a rapid hepatocyte pyroptosis mediated by the Apaf-1 pyroptosome/caspase-3/GSDME signaling pathway. The interaction of these two processes triggers liver organ failure, suggesting GSDMD/GSDME as targets for the treatment of liver damage/liver failure in sepsis . Based on high-throughput drug screening and validation in in vivo and in vitro models, it was found that the combination of the old drug mecobalamin with ceftriaxone sodium, or with thiamine, used therapeutically, can block both of these cell pyroptosis pathways. Compared with corticosteroid drugs like dexamethasone and liver-protecting drugs, they have superior effects. Patients were randomly divided into intervention and control groups, with both groups receiving standard treatment and care for sepsis (decided by the attending physician). On this basis, the following treatments were administered: Control group (n=20): intravenous saline drip/oral placebo tablets; Intervention group (n=20): intravenous drip of ceftriaxone sodium 1g per dose, twice daily (continuously for 14 days), mecobalamin injection 1mg per dose, once daily (on days 1, 2, 3, 5, 7, 9, 11, 13), with a half-hour interval between medications. From day 15 to 28, take mecobalamin tablets orally, 1mg per dose, three times a day.
The long-term goal of our work is to evaluate the effect of intensive postpartum blood pressure control on maternal cardiovascular health, risk of chronic hypertension, and reversal of vascular dysfunction generated by hypertensive disorders of pregnancy, thus attenuating the lifelong trajectory of cardiovascular disease risk.
Sepsis is a disruption of homeostasis in the human body in response to bloodstream infection and is associated with a high risk of mortality. Worldwide, sepsis is affecting approximately 30 million people and resulting in six million deaths. Blood culture is a specific blood sample used to identifying microbial agent (bacterium or yeast) and determine the sensitivity of these microorganisms to antibiotics and antifungals. Any delay in identifying the microorganism and/or determining the AST (antibiotic susceptibility testing) has a direct impact on the administration of appropriate antibiotic treatment and, consequently, on mortality of the patient. The faster the diagnosis, the faster the antibiotic treatment will be adapted, the higher the survival rate/probability of patients, and the lower the ecological impact. In routine, clinical microbiology laboratories currently use 2 automatized techniques: MALDI-TOF MS® for microorganisms identification and VITEK2® method for AST determination. Based on a proteomic approach, the IDBIORIV method is a rapid method (90 minutes) in comparison of current methods (24/48 hours) able to identifying a large panel of 113 pathogens and determine the antibiotic resistance profile of 49 species for 4 classes of antibiotics (Beta-lactams, Aminosides, Glycopeptides, Colistin). The main objective of this study is to evaluate the performance of the IDBIORIV method in pathogen identification and antibiotic susceptibility testing in comparison with current methods of analysis of positive blood cultures used at the microbiology laboratory of the Hospices Civils de Lyon, in a real clinical situation, over a 2-year period.
The goal of this clinical trial is to compare two timings of steroid treatment in patients with severe infection who develop low blood pressure. The main question it aims to answer is: • Which timing strategy is better between starting steroid treatment very early in the course of severe infection, or waiting until the patient does not respond to medicine that raises blood pressure according to the current guidelines? Participants will receive either early steroid treatment or placebo right after they develop low blood pressure from infection. Both participants and treating doctors will not know which treatment participants received. When blood pressure goal is not reached after a moderate dose of drugs that raise blood pressure, an open-label steroid treatment will be given to participants as indicated in the current guidelines.
Toxicosis often leads to multiple organ failure (MODS), with the kidney being the primary target organ due to its sensitivity to infection and ischemia. The kidney's vulnerability makes it a potential early indicator of organ failure, implying that further organ failure may occur later, thereby increasing the risk of patient mortality. Several studies conducted on sepsis patients in the Pediatric Intensive Care Unit (PICU) have revealed that 40.32% of sepsis patients experienced complications with acute kidney injury (AKI), and the case fatality rate could rise to 70% once AKI occurred. The Kidney Disease Improving Global Outcomes (KDIGO) scale is commonly used as a diagnostic criterion for AKI. However, the kidney's robust reserve function poses a challenge for early identification, diagnosis, and intervention of AKI since significant increases in creatinine levels and a sharp decrease in urine volume already indicate severe kidney damage. This situation calls for the development of alternative methods. In our previous study, we discovered a strong correlation between urinary oxygen partial pressure and renal organ function impairment in children with sepsis. Building upon traditional biochemical indicators such as blood lactic acid levels, we will incorporate non-invasive tests like urine partial pressure of oxygen, renal ultrasound, and cardiac ultrasound, as well as novel markers like KIM-1, to establish a model for early recognition and assessment of kidney damage in children with sepsis. By utilizing commonly used biomarkers and the precise effects of urinary oxygen partial pressure, we aim to improve early identification and accurate intervention evaluation for pediatric sepsis kidney injury. This research will provide a crucial foundation for the development of early warning systems, diagnostic guidelines, and treatment protocols for pediatric sepsis kidney injury.
Objective of the study is to compare the efficacy and safety of 'Short duration antibiotic' (72hrs) and 'Standard duration antibiotic'(5 - 7days) in preterm neonates ( >28weeks and >1000grams ) with culture negative early onset sepsis.
This is a prospective observational cohort study of platelet phenotype in pregnant patients at high-risk for the development preeclampsia. Blood samples will be collected prior to the initiation of daily aspirin and again in the second trimester to evaluate for platelet changes during pregnancy in patient's as a result of aspirin use and their association with adverse perinatal outcomes.
This study sought to evaluate the association of right ventricular systolic dysfunction and 28-day in-hospital mortality in patients with sepsis and septic shock. Prospective cohort study of adult patients admitted at Burapha university hospital from October 1, 2022 through June 30, 2023 for sepsis and septic shock, who had an echocardiogram within 72 hours after admission for evaluating right ventricular systolic function. Right ventricular systolic dysfunction was defned by the American Society of Echocardiography criteria. Outcomes included 28-day in-hospital mortality, maximal blood lactate, length of intensive care unit(ICU) stay and duration of mechanical ventilation.
