Impaired balance between coronary blood flow and myocardial metabolism in postpartum swine.

Understanding of the mechanisms contributing to the increased maternal susceptibility for major adverse cardiovascular events in the postpartum period remains poor. Accordingly, this study tested the hypothesis that the balance between coronary blood flow and myocardial metabolism is compromised during the puerperium period (35-45 days post-delivery) in swine. Systemic and coronary hemodynamic responses were assessed in anesthetized, open-chest control (nonpregnant) and puerperium/postpartum swine at baseline and in response to intravenous infusion of dobutamine (1-30 μg/kg/min).

Evaluation of Secondary Overtriage at a Rural Level 1 Trauma Center.

Objective: To retrospectively assess the prevalence of secondary overtriage (SO) within a rural regional Appalachian health care system.

Methods: Trauma registry data was extracted for all trauma activation transfer patients from 2017 to 2022. Transferred patients were then stratified into two groups, non-secondary overtriage (non-SO) or SO.

Examining the potential impacts of a coastal renourishment project on the presence and abundance of Escherichia coli.

Erosion poses a significant threat to oceanic beaches worldwide. To combat this threat, management agencies often utilize renourishment, which supplements eroded beaches with offsite sand. This process can alter the physical characteristics of the beach and can influence the presence and abundance of microbial communities.

Effects of Trauma Center Consolidation on Adult Trauma at a Rural Level 1 Trauma Center.

Objective: The aim was to determine the impact of consolidation of two rural level 1 trauma centers on adult trauma patients presenting to the remaining level 1 trauma center. To our knowledge, a study assessing the impact of trauma center consolidation on adult trauma patients had yet to be performed.

Methods: A single institution, retrospective study was conducted at a rural level 1 trauma center.
