Conservation of carbon resources and values on public lands: A case study from the National Wildlife Refuge System.

Public lands in the United States are those land areas managed by federal, state, and county governments for public purposes such as preservation and recreation. Protecting carbon resources and increasing carbon sequestration capacity are compatible with public land management objectives for healthy and resilient habitats, i.e.

A Retrospective Analysis of Adverse Events in Hyperbaric Oxygen Therapy (2012-2015): Lessons Learned From 1.5 Million Treatments.

Objective: To describe the distribution and occurrence of adverse events recorded during hyperbaric oxygen (HBO) therapy from 2012 to 2015. In this analysis, events are defined as otic/sinus barotrauma, confinement anxiety, hypoglycemia, oxygen toxicity, pneumothorax, seizure, and shortness of breath.

Data And Analysis: The data for the analysis were drawn from a proprietary electronic health data system that contained information on 1,529,859 hyperbaric treatments administered during 53,371 treatment courses from 2012 to 2015 in outpatient wound care centers across the United States managed by Healogics, Inc, Jacksonville, Florida.

Rapid identification of slow healing wounds.

Chronic nonhealing wounds have a prevalence of 2% in the United States, and cost an estimated $50 billion annually. Accurate stratification of wounds for risk of slow healing may help guide treatment and referral decisions. We have applied modern machine learning methods and feature engineering to develop a predictive model for delayed wound healing that uses information collected during routine care in outpatient wound care centers.

Frequency of debridements and time to heal: a retrospective cohort study of 312 744 wounds.

Importance: Chronic wounds usually get trapped in the inflammatory stage of wound healing; however, aggressive debridement transforms chronic wounds to acute wounds and therefore complete healing.

Objective: To investigate healing outcomes and debridement frequency in a large wound data set.

Design: Retrospective cohort study.

Doxycycline as a modulator of inflammation in chronic wounds.

 Doxycycline is a semisynthetic, chemically modified tetracycline compound that is rapidly absorbed and exerts biological effects independent of its antimicrobial activity. One such effect includes the inhibition of matrix metalloproteinases. Doxycycline has a long history as a collagenase inhibitor.

Ultrasound-mediated oxygen delivery to lower extremity wounds.

Critical limb ischemia (CLI), an end result of peripheral ar- terial disease, remains a major clinical challenge. Wound healing in patients with CLI can be difficult due to diminished tissue oxygen- ation, often leading to recalcitrant ulcers and frequent limb loss. Nu- merous therapies, including hyperbaric oxygen therapy (HBOT), have been used to correct this regional ischemia, although often with mixed results.

Trout population responses to restoration of stream flows.

There are numerous demands for the limited water supplies in the Rocky Mountain (USA) region, and controversies surrounding instream flows abound. A specific problem involves water diversions (i.e.
