Defining Posterior Wall Fragments in Associated Both Column Acetabular Fractures (OTA/AO 62C).

Objective: Associated both column acetabular fractures (OTA/AO 62C) with concomitant posterior wall fracture fragments (ABC + PW) have not been well-defined. The purpose of this study was to report on the incidence and morphology of ABC + PW fractures.

Methods: A retrospective review of associated both column (ABC) fractures between 2014 and 2020 was performed.

Evaluation of the R2D2 protocol: A Novel Method for Assessing Emergency Department Disposition for Residents.

Background: The emergency department (ED) disposition and discharge process is a critical period in a patient's transition from an acute care setting to self-care or a bridge to other healthcare providers. The emergency physician plays a pivotal role in this process and is ultimately responsible for ensuring that patients are safely released from their care. We developed a protocol to guide residents through the ED discharge process using the mnemonic "R2D2": reassess the patient, recheck the workup, discuss the disposition plan with the attending, and finally discuss the discharge plan with the patient.

Remodeling of the tight junction during recovery from exposure to hydrogen peroxide in kidney epithelial cells.

Renal ischemia-reperfusion injury results in oxidative stress-induced alterations in barrier function. Activation of the mitogen-activated protein (MAP) kinase pathway during recovery from oxidative stress may be an effector of oxidant-induced tight junction reorganization. We hypothesized that tight junction composition and barrier function would be perturbed during recovery from oxidative stress.
