Catheter securement systems: comparison of two investigational devices to a sutureless securement device, a securement dressing, and sutures in a pig model.

Background: Catheter securement is critical for the success of infusion therapy and to prevent complications. Our purpose was to compare the strength of catheter securement achieved with two investigational adhesive securement devices to two securement products and also to sutures using an in vivo animal model.

Methods: Twenty-five live pigs were prepared for aseptic abdominal surgery.

Nitric oxide levels in wound fluid may reflect the healing trajectory.

We analyzed nitric oxide metabolites (nitrate and nitrite, NOx) and other biomarkers in human wound fluids and correlated these markers with wound healing status (progressing or worsening) based on patient's wound history. Samples were collected pre- and postcleansing from patients with wounds of various etiologies and analyzed for NOx, matrix metalloproteinase activity, and elastase activity. A laboratory method was developed to analyze NOx which can detect at least 5 μM in samples as small as 10 μL.

Dietary intake and food sources of whole grains among US children and adolescents: data from the 1994-1996 Continuing Survey of Food Intakes by Individuals.

Objective: This study characterizes whole grain consumption among a nationally representative sample of US children and adolescents.

Design: Data used in this study were collected as part of the 1994-1996 US Department of Agriculture Continuing Survey of Food Intakes by Individuals (CSFII).

Subjects/setting: CSFII was designed to obtain a nationally representative sample of noninstitutionalized persons of all ages residing in the United States.
