Unusual Cause of a Cardiac Arrest in a Former African American Collegiate Athlete.

Yamaguchi-variant cardiomyopathy is an underreported but significant cause of cardiac arrest among athletes. We studied the hospital course of one patient who arrived at the emergency department after a sudden cardiac arrest while playing a recreational basketball game. We used the electronic medical record (Epic) to follow the notes, labs, imaging, and procedures that were performed.

Using machine learning algorithms to enhance the diagnostic performance of electrical impedance myography.

Introduction/aims: We assessed the classification performance of machine learning (ML) using multifrequency electrical impedance myography (EIM) values to improve upon diagnostic outcomes as compared to those based on a single EIM value.

Methods: EIM data was obtained from unilateral excised gastrocnemius in eighty diseased mice (26 D2-mdx, Duchenne muscular dystrophy model, 39 SOD1G93A ALS model, and 15 db/db, a model of obesity-induced muscle atrophy) and 33 wild-type (WT) animals. We assessed the classification performance of a ML random forest algorithm incorporating all the data (multifrequency resistance, reactance and phase values) comparing it to the 50 kHz phase value alone.

[18F-fluorothymidine preclinical study in non-human primate. Dosimetry and biodistribution].

Positron emission tomography-computed tomography (PET-CT) is part of the new diagnostic and therapeutic algorithms for Hodgkin lymphoma. PET-CT is a valuable tool for the assessment of treatment response and prognosis, both by means of interim PET-CT with 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) as well as end of treatment (EOT) PET-CT. Given the low specificity of [18F]FDG for the diffuse large B cell lymphoma (DLBCL), there is an emerging need for a more specific radiopharmaceutical agent.

No Pain and No Gain: Kommerell's Diverticulum with a Right-Sided Aortic Arch, and an Aberrant Left Subclavian Artery Presenting in a Body Builder with Muscle Bulk Imbalance.

A 22-year-old right-handed male presented to the Sports Medicine clinic with concerns of upper extremity muscle asymmetry. Physical examination showed gross muscular asymmetry when comparing the left upper extremity to the right. Radial pulses were 2 + on the right and 1 + on the left.
