Development and Evaluation of a Presenter Coaching Program at an Academic Surgical Conference.

Objective: Presenting at academic conferences is an important means of disseminating research, networking, and building a professional reputation, but the quality of presentations at conferences is often suboptimal. This project describes the design, implementation, and evaluation of a presentation coaching program offered by an academic surgical society to presenters at its annual meeting.

Design: Oral presenters were paired with a coach and encouraged to meet independently, yet coaching was unstructured.

Influence of the Variability in Motor Unit Discharge Times and Neural Drive on Force Steadiness During Submaximal Contractions with a Hand Muscle.

Our purpose was to compare the influence of the spectral content of motor unit recordings on the calculation of electromechanical delay and on the prediction of force fluctuations from measures of the variability in discharge times and neural drive during steady isometric contractions with the first dorsal interosseus muscle. Participants ( = 42; 60 ± 13 yrs) performed contractions at 5% and 20% MVC. After satisfying inclusion criteria, high-density surface EMG recordings from a subset of 23 participants were decomposed into the discharge times of 530 motor units.

Synthesis and evaluation of 6-arylaminobenzamides as positron emission tomography imaging ligands for the sphingosine-1-phosphate-5 receptor.

The sphingosine-1-phosphate-5 (S1P) receptor is one of the five membrane G protein-coupled receptors that are activated by the lysophospholipid, sphingosine-1-phosphate, resulting in regulation of many cellular processes. S1P receptors are located on oligodendrocytes and are proposed to influence oligodendrocyte physiology. Understanding S1P modulation during processes such as remyelination could have potential applications for demyelinating CNS disorders such as multiple sclerosis (MS).

How to Use Imaging: Complex Cases of Atherosclerosis, Myocardial Inflammation, and Cardiomyopathy in Cardio-Oncology.

It is well understood that cancer therapies including chemotherapy, tyrosine kinase inhibitors, immune checkpoint inhibitors, and radiation can increase the risk of cardiovascular disease in patients with cancer. This can manifest as a multitude of pathologies including left ventricular dysfunction, myocarditis, cardiomyopathy, accelerated atherosclerosis, and coronary vasospasm. Multimodal cardiac imaging plays a critical role in diagnosing such pathologies by relying on noninvasive tools including echocardiograms, cardiac magnetic resonance imaging, positron emission tomography, single-photon emission computed tomography, and coronary computed tomography angiography.
