Introduction of oral feeding in premature infants on high flow nasal cannula in a level IV neonatal intensive care unit: a quality improvement initiative.

Background: Failure to reach full oral feeding remains a significant barrier for premature infants to discharge home. Postmenstrual age (PMA) at first oral feeding is significantly associated with the length of hospital stay (LOS).

Methods: Single-center QI to introduce oral feeding to infants on high-flow nasal cannula (HFNC) by reducing the flow to 2 L during feeds.

Using evidence-based leadership initiatives to create a healthy nursing work environment.

In an effort to create a healthy nursing work environment in a military hospital Intermediate Care Unit (IMCU), a facility-level Evidence Based Practice working group composed of nursing.Stakeholders brainstormed and piloted several unit-level evidence-based leadership initiatives to improve the IMCU nursing work environment. These initiatives were guided by the American Association of Critical Care Nurses Standards for Establishing and Sustaining Healthy Work Environments which encompass: (1) skilled communication, (2) true collaboration, (3) effective decision making, (4) appropriate staffing, (5) meaningful recognition, and (6) authentic leadership.

Highly crosslinked vs conventional polyethylene particles: relative in vivo inflammatory response.

Crosslinked polyethylenes have been introduced to reduce wear and osteolysis. The osteolysis rate depends on many factors including the biologic activity of the wear particles. This study examines the relative inflammatory potential of highly crosslinked and non-crosslinked polyethylene particles.

Highly crosslinked vs conventional polyethylene particles--an in vitro comparison of biologic activities.

Highly cross-linked polyethylenes (HXPEs) have been introduced to reduce wear after hip arthroplasty. The improved wear characteristics of HXPEs are well documented, but the relative biologic activity of HXPE and conventional polyethylene (CPE) particles remains unclear. Longevity (Zimmer, Warsaw, Ind; HXPE) and GUR 1050 (Zimmer; CPE) particles were isolated and characterized from a hip simulator and their in vitro inflammatory responses (tissue necrosis factor *, interleukin 1*, and vascular endothelial growth factor levels) were compared using macrophages.

Volume analysis of arthroscopic capsular shift.

Purpose: To determine how much volume reduction can be obtained with varying amounts of arthroscopic capsular plication.

Methods: Six fresh-frozen, cadaveric specimens were used. Specimens were rejected if a rotator cuff tear was present.
