Supporting Physicians and Practice Teams in Efforts to Address the Opioid Epidemic.

Primary care physicians and practice teams increasingly recognize the need to take a role in addressing the growing epidemic of opioid use disorder (OUD) and opioid-related drug overdose deaths, but face considerable challenges in doing so. Through its work supporting practice transformation efforts, sharing innovations, and connecting key sectors within communities, the Network for Regional Healthcare Improvement and several of its member regional health improvement collaboratives have identified innovative ways to support physicians and practice teams in transforming practice in ways that address a spectrum of issues related to opioid use. These strategies include efforts to prevent, identify, and treat opioid addiction, including reducing inappropriate prescribing; improving opioid prescribing safety; compassionately tapering chronic and/or high-dose opioid regimens; appropriately screening for and identifying OUD; initiating treatment with evidence-based medications for OUD within practice settings; and prescribing life-saving naloxone to reverse opioid overdose.

Modeling dermal granulation tissue with the linear fibroblast-populated collagen matrix: a comparison with the round matrix model.

Background: Wound contraction typically is not symmetrical; for example, a square-shaped wound will not yield a square scar. Interestingly, the round fibroblast-populated collagen matrix has been used as a model of wound contraction, even though contraction in this model is mostly symmetrical.

Objective: We wanted to compare the round versus linear fibroblast-populated collagen matrix to see which would be a better model of dermal granulation tissue.

Quantification of a rat tail vertebra model for trabecular bone adaptation studies.

A feedback controlled loading apparatus for the rat tail vertebra was developed to deliver precise mechanical loads to the eighth caudal vertebra (C8) via pins inserted into adjacent vertebrae. Cortical bone strains were recorded using strain gages while subjecting the C8 in four cadaveric rats to mechanical loads ranging from 25 to 100 N at 1 Hz with a sinusoidal waveform. Finite element (FE) models, based on micro computed tomography, were constructed for all four C8 for calculations of cortical and trabecular bone tissue strains.
