Summary: 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 cha...

Summary: Chronic airways infection with Pseudomonas aeruginosa (PA) is associated with increased frequency of exacerbations, deterioration in quality of life and increased mortality in adult patients with bronchiectasis. Current guidelines suggest the prescription of an eradication antibiotic treatment for a first episode of PA infection (early PA infection). Several antibiotic regimens may be proposed, ra...

Summary: The purpose of this study is to evaluate how Aztreonam (ATM) and Avibactam (AVI) are processed in pediatric participants. This study also aims to understand participant safety and effects in pediatric participants. The study is seeking participants who are: * 9 months to less than 18 years of age * Hospitalized * Suspected/known to have a gram-negative infection * Receiving intravenous (iv, given ...

Summary: The purpose of this study is to learn about the safety and effects of ATM-AVI for the possible treatment of infections caused by a type of bacteria called gram-negative bacteria. The study medicine is a combination of an antibiotic, aztreonam (ATM), and another medicine, avibactam (AVI), which is used to help stop bacteria from being resistant to antibiotics. Antibiotics are medicines that fights ...

Summary: Infections are a common complication in patients with cancer. They are a significant cause of complications and death in this population. Patients with cancer and low neutrophil counts due to chemotherapy or disease often have a fever and receive antibiotic treatment. The optimal duration of this treatment is largely unknown. Late, there have been some data suggesting the safety of early discontin...

Summary: The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treati...

Summary: This randomised controlled trial will determine the non-inferiority of stopping empiric antibiotics prior to absolute neutrophil count (ANC) recovery (Early Stopping) versus stopping antibiotics upon ANC recovery (Standard of Care/ Late Stopping) , in children with cancer and high-risk febrile neutropenia (FN).

Summary: Biofilm formation is an important cause of catheter-related infection. In hemodialysis, use of an antibiotic-lock has been proven to be effective to manage such a complication with preservation of the central venous catheter. In peritoneal dialysis, while biofilm has been implicated in relapsing and repeat peritonitis, both of which are caused by the identical bacteria as in their preceding perito...

Summary: Multi center, retrospective chart review of patients admitted to MHS hospitals from April 1, 2017 to March 31, 2022. Patients will be identified through the electronic medical record, and data from those that meet the study inclusion and exclusion criteria will be analyzed. Minimum inhibitory concentration (MIC) data will be interpreted per Clinical \& Laboratory Standards Institute (CLSI) standar...

Summary: Intravitreal injection (IVI) is an ophthalmological procedure used worldwide to treat ocular conditions. Its use has been steadily increasing for several years, because this method of drug delivery minimizes systemic exposure and allows for intraocular drug levels not achievable through systemic or topical drug administration. IVI of agents such as anti-vascular endothelial growth factor (anti-VEG...

Summary: Little is known of beta-lactam antibiotics' true therapeutic plasma concentration range. The aims of this study are to define evidence-based, safe and effective upper and lower limits of the plasma concentrations of imipenem, meropenem, amoxicillin, flucloxacillin, piperacillin, ceftazidime and cefepime in patients at increased risk of serious bacterial infections and currently understudied pharma...

Summary: The investigator's purpose is to study the population pharmacokinetics of commonly used antimicrobial agents in children of bacterial meningitis with augmented renal clearance and assess dosage individualization feasibility.
