Improving Anesthesia Providers' Needle Cricothyrotomy Success With Ultrasound-Guidance: A Cadave Quality Improvement Project.

Difficult and failed airway management remains a significant cause of anesthesia-related morbidity and mortality. Failed airway management guidelines include performing a cricothyrotomy as a final step. Correct identification of the cricothyroid membrane (CTM) is essential for safe and accurate cricothyrotomy execution.

Kinematic and dynamic gait compensations resulting from knee instability in a rat model of osteoarthritis.

Introduction: Osteoarthritis (OA) results in pain and disability; however, preclinical OA models often focus on joint-level changes. Gait analysis is one method used to evaluate both preclinical OA models and OA patients. The objective of this study is to describe spatiotemporal and ground reaction force changes in a rat medial meniscus transection (MMT) model of knee OA and to compare these gait measures with assays of weight bearing and tactile allodynia.

Pain coping skills training and lifestyle behavioral weight management in patients with knee osteoarthritis: a randomized controlled study.

Overweight and obese patients with osteoarthritis (OA) experience more OA pain and disability than patients who are not overweight. This study examined the long-term efficacy of a combined pain coping skills training (PCST) and lifestyle behavioral weight management (BWM) intervention in overweight and obese OA patients. Patients (n=232) were randomized to a 6-month program of: 1) PCST+BWM; 2) PCST-only; 3) BWM-only; or 4) standard care control.

Kinematic and dynamic gait compensations in a rat model of lumbar radiculopathy and the effects of tumor necrosis factor-alpha antagonism.

Introduction: Tumor necrosis factor-α (TNFα) has received significant attention as a mediator of lumbar radiculopathy, with interest in TNF antagonism to treat radiculopathy. Prior studies have demonstrated that TNF antagonists can attenuate heightened nociception resulting from lumbar radiculopathy in the preclinical model. Less is known about the potential impact of TNF antagonism on gait compensations, despite being of clinical relevance.

Technical note: out-of-plane angular correction based on a trigonometric function for use in two-dimensional kinematic studies.

In two-dimensional (2D) kinematic studies, limb positions in three-dimensional (3D) space observed in lateral view are projected onto a 2D film plane. Elbow and knee-joint angles that are less than 20 degrees out-of-plane of lateral-view cameras generally exhibit very little measurable difference from their 3D counterparts (Plagenhoef 1979 Environment, Behavior, and Morphology; New York: Gustav Fisher, p. 95-118).
