Suggested Dosing of Select Beta-lactam Agents for the Treatment of Antimicrobial-Resistant Gram-Negative Infections in Children.

Background: The Infectious Diseases Society of America (IDSA) publishes annual guidance on the treatment of antimicrobial-resistant (AMR) gram-negative infections. Within the AMR guidance, suggested dosages of antibiotics for adults infected with AMR pathogens are provided. This document serves as a companion document to the IDSA guidance to assist pediatric specialists with dosing β-lactam agents for the treatment of AMR infections in children.

Vitronectin regulates lung tissue remodeling and emphysema in chronic obstructive pulmonary disease.

Vitronectin (VTN) is an important extracellular matrix protein in tissue remodeling, but its role in COPD is unknown. We show that VTN regulates tissue remodeling through urokinase plasminogen activator (uPA) signaling pathway in COPD. In human COPD airways and bronchoepithelial cells and the airways of mice with cigarette smoke (CS)-induced experimental COPD, VTN protein was not changed, but downstream uPA signaling was altered (increased plasminogen activator inhibitor-1, uPAR) that induced collagen and airway remodeling.

Transfer from long-term care to acute care and risk of new permanent cognitive or physical disability among long-term care residents in Canada: protocol for a retrospective cohort study.

Introduction: Long-term care (LTC) residents are frequently transferred to acute care hospitals. Transfer decisions should align with residents' wishes and goals. Decision to transfer to hospital, when not aligned with the resident's wishes, can result in transfers that are harmful to residents, leaving residents in a state of disability that could be considered worse than death.

Incidence and Outcomes of Prosthetic Valve Endocarditis in Adults with Congenital Heart Disease.

Background: Patients with congenital heart disease (CHD) often require prosthetic valve implantation, increasing their lifetime risk of developing prosthetic valve endocarditis (PVE). The purpose of this study was to determine the incidence, risk factors, and outcomes of PVE in adults with CHD.

Method: Retrospective cohort study of adults with CHD and prior prosthetic valve implantation (2003-2023).
