Filter by:Fluorescence is one of the most commonly used research and detection techniques in the field of biomedical science. The characteristics of fluorescent probe directly affect the performance and application of fluorescence analysis and imaging. Aggregation-Caused Quenching has limited the application of traditional fluorescent probes to some extent. This project intends to systematically evaluate the detection efficiency of new methods through the detection of biomarkers in clinical samples and the comparison with the detection methods of traditional biomarkers, so as to provide theoretical and experimental basis for the establishment of fast and simple biomarker detection technologies with new biological probes.
The focus of this study is to explore the variability distribution of 5-Aminolevulinic Acid (ALA)associated with bone and soft tissue perfusion in infection patients, using 5-ALA fluorescence imaging. In additional this study plans to evaluate the change in 5-ALA distribution from pre to post debridement and to preliminarily determine whether an orally administered dose of 20mg/kg 5-ALA can predict recurrent infection/treatment failure.
Chronic kidney disease (CKD) is associated with an increased cardiovascular mortality. In particular children with early-onset CKD have a lifelong increased risk to suffer from cardiovascular disease (CVD). Therefore, children with CKD deserve our attention. The immune system in children with CKD is disturbed, exhibiting pro-inflammatory features. Therefore, we aim to learn more about the characteristics of the immune system in early-onset CKD. In this project PBMC of pediatric CKD patients and age-matched healthy controls will be analysed and compared using CITE-Seq as a multimodal scRNAseq phenotyping method. All patients will be clinically characterized to integrate cardiovascular and immunological data.
The main purpose of the extension phase of this study is to evaluate the longer-term immune persistence of mRNA-1647 vaccine administered to CMV-seronegative and CMV-seropositive adults who completed Study mRNA-1647-P202 (NCT04232280). For participants in the optional booster phase (BP), the main purpose is to evaluate the long-term immunogenicity and safety of the mRNA-1647 vaccine in both participants receiving a booster dose (BD) and those not receiving a BD, and to additionally evaluate the reactogenicity in participants receiving a BD.
Part 1 is a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of single and multiple ascending doses of EDP-721 in healthy subjects. Part 2 is a randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics and antiviral activity of EDP-721 in combination with EDP-514 in patients with chronic hepatitis B virus infection.
The objective of this study is the collection and testing of clinical samples to determine the clinical performance of the Access HIV Ag/Ab Combo assay on the DxI 9000 Access Immunoassay Analyzer
Surgical Site Infections (SSI) develop as a complication of surgical care 30-90 days after surgery without implants and within 1 year after implanted operations. Despite advances in asepsis practices, sterilization methods, surgical technique and antibiotic prophylaxis, SSI is the most important cause of hospital stay, morbidity and even mortality. SSI, which constitutes approximately 20% of healthcare associated infections (HAI) all over the world, is also the HAI with the highest cost. Although it has been reported that 60% of the SSI can be prevented by using evidence-based guidelines, 2-5% of the operated patients develop SSI, the hospital stay of patients with SSI is 7-11 days longer, the risk of death increases 2-11 times, It was reported that the cause of death was direct SSI. In the United States of America (USA), SSI constitutes 31% of HAI, it is seen in 2-5% of inpatients, approximately 160,000-300,000 SSIs occur each year, the most common and costly HAI.Abdominal surgery; It includes the treatment of diseases of organs such as stomach, gall bladder, pancreas, spleen, liver, small intestine and large intestine. It has been reported that the incidence of SSIs after abdominal surgery is 15-25% higher than other types of surgery. In a study conducted by Alcan et al. (2020), 69.8% of nurses stated that they used Povidone Iodine as skin antisepsis. Wistrand et al. (2015) compared preoperative 36 ° C and room temperature 20 ° C Chlorhexidine Gluconate solutions, but reported that there was no difference in bacterial colonization and SSI rates. In their study in Turkey, Gezer et al. (2020) reported that the prevalence of SSI was significantly lower in the Povidone Iodine group heated to 37 ° C before surgery compared to the Povidone Iodine group applied at 25 ° C room temperature.
The goal of open extremity fracture (OEF) treatment is to promote fracture healing and restore function while preventing the development of infection. This is achieved through systematic and timely wound debridement and irrigation, fracture stabilization, tetanus prophylaxis, systemic and local antimicrobial therapy, and judicious timing of wound closure based on cleanliness. Early prophylactic systemic antibiotics lower infection rates in open fractures but have limitations of achieving adequate concentration at the hypoperfused wound area. OEF wounds are frequently poor in vasculature secondary to the soft tissue injury, hence adequate concentration of antibiotic cannot permeate to the tissue at risk. If systemic antibiotic concentrations are increased to achieve minimum inhibitory concentration (MIC) for pathogens at the wound, there is heightened concern for systemic drug toxicity. In sharp contrast, locally administered antibiotics achieve high drug concentration directly within the wound cavity with minimal systemic side effects. Local antibiotic therapy has shown to reduce rates of open fracture wound infection. With the serious implications of postoperative infections in OEF, it is imperative that all measures including further use of prophylactic local antibiotics be considered to prevent fracture-related infection (FRI). The overarching hypothesis for this project is that a novel synergistic combination of local aqueous tobramycin plus perioperative weight-based IV cephalosporin antibiotic prophylaxis will reduce the rate of FRI one year after OEF surgery. This in turn will improve OEF patient outcomes, decreasing morbidity and return to the operating room (OR) without any adverse effect on fracture healing. Regardless of the treatment group, bacterial speciation will be determined for patients that do develop FRI to help guide future treatment. The goal is to improve the clinical outcome and recovery of the population that sustains an OEF by decreasing the rate of FRI and fracture nonunions while concurrently educating on bacterial speciation and resistance.
Caspofungin is an anti-fungal drug mainly metabolized by the liver. The pathophysiological status of children with severe infection will affect the metabolism of caspofungin in the body especially in the case of liver dysfunction. There is little metabolism of caspofungin through the kidney and continuous renal replacement therapy and renal function have little influence on the pharmacokinetics of caspofungin. The study aim to investigate PK/PD of caspofungin in children with specific pathophysiological conditions, such as liver insufficiency, hypoproteinemia, ECMO treatment, or sepsis.
Ceftazidime avitbatan sodium is a broad-spectrum antibiotic with an antimicrobial spectrum covering resistant gram-negative bacteria. Its use in pediatric intensive care for severe infections is not unusual. Pathophysiological changes in severe sepsis can lead to significant changes in pharmacokinetics and pharmacodynamics during continuous renal replacement therapy.This research aims to study change of pharmacokinetic and pharmacodynamic in severe infection children with extracorporeal life support, thus improve the treatment of severe sepsis and sepsis shock.
