Quantity of Caloric Support After Pediatric Severe Traumatic Brain Injury: Description of Associated Outcomes in a Single Retrospective Center Cohort, 2010-2022.

Objectives: To examine the relationship between adequacy of caloric nutritional support during the first week after severe traumatic brain injury (TBI) and outcome.

Design: Single-center retrospective cohort, 2010-2022.

Setting: Tertiary care children's hospital with a level 1 trauma center.

The lived experience of nurse practitioners practicing within the Transformational Advanced Professional Practice Model: A phenomenological study.

Purpose: The purpose of this study was to describe the lived experiences of nurse practitioners (NPs) practicing within the Transformational Advanced Professional Practice (TAPP) Model, a professional practice model (PPM).

Data Sources: A descriptive phenomenological analysis using semistructured interviews of 11 NPs across multiple inpatient and outpatient clinical areas at Texas Children's Hospital. Member checking and theming data occurred using Colaizzi's Method concurrently with Mind Mapping technique.

Development of the transformational advanced professional practice model.

Purpose: The purpose of this article is to describe the development of a professional practice model (PPM) for advanced practice registered nurses (APRNs).

Data Sources: A literature review was conducted on PPMs. Simultaneous review of authoritative resources, including The National Organization of Nurse Practitioner Faculties (NONPF) and the Licensure, Accreditation, Certification and Education (LACE) Consensus Model, was performed.

Are anomalous invasion speeds robust to demographic stochasticity?

Two important issues for conservation are the range expansion of species as a result of climate change and the invasion of exotic species. Being able to predict the rate at which species spread is key for successful management. In deterministic models, the invasion speed of a polymorphic population can be faster than that of any of the component phenotypes, and these "anomalous" invasion speeds persist even when the mutation rate between phenotypes is vanishingly small.

Health information exchange reduces repeated diagnostic imaging for back pain.

Study Objective: This study seeks to determine whether health information exchange reduces repeated diagnostic imaging and related costs in emergency back pain evaluation.

Methods: This was a longitudinal data analysis of health information exchange patient-visit data. All repeated emergency department (ED) patient visits for back pain with previous ED diagnostic imaging to a Memphis metropolitan area ED between August 1, 2007, and July 31, 2009, were included.

Dispersal polymorphism and the speed of biological invasions.

The speed at which biological range expansions occur has important consequences for the conservation management of species experiencing climate change and for invasion by exotic organisms. Rates of dispersal and population growth are known to affect the speed of invasion, but little is known about the effect of having a community of dispersal phenotypes on the rate of range expansion. We use reaction-diffusion equations to model the invasion of a species with two dispersal phenotypes into a previously unoccupied landscape.
