Frequency of Bacteremia and Urinary Tract Infection in Pediatric Renal Transplant Recipients.

Background: Our primary goal was to determine the frequency of bacteremia and urinary tract infections (UTI) in pediatric renal transplant recipients presenting with suspected infection within 2 years of transplant and to identify clinical and laboratory factors associated with bacteremia.

Methods: We conducted a retrospective cross-sectional study for all pediatric ( < 18 years old) renal transplant recipients seen at 3 large children's hospitals from 2011 to 2018 for suspected infection within 2 years of transplant date, defined as pyrexia ( > 38°C) or a blood culture being ordered. Patients with primary immunodeficiencies, nontransplant immunosuppression, intestinal failure, and patients who had moved out of the local area were excluded.

Association of influenza outbreaks with advanced pediatric medical support.

Retrospective data evaluated increases in advanced medical support for children with medically attended acute respiratory illness (MAARI) during influenza outbreak periods (IOP). Advanced support included hospitalisation, intensive care unit admission, or mechanical ventilation, for children aged 0-17 years hospitalised in Maryland's 50 acute-care hospitals over 12 influenza seasons. Weekly numbers of positive influenza tests in the Maryland area defined IOP for each season as the fewest consecutive weeks, including the peak week containing at least 85% of positive tests with a 2-week buffer on either side of the IOP.
