Happy April and welcome to the highlights and review of the AMAZING material published over the last quarter in Current Sports Medicine Reports (CSMR).

See you in Atlanta!

From time-to-time CSMR publishes Invited Commentaries. I’ve highlighted an important Invited Commentary from this past quarter below:

Rural-Nonrural Disparities in Sports Medicine Access in Secondary School Athletics in Virginia authored by Sean T. Thuesen, DO, MS, ATC and Mark Rogers, DO, CAQSM. I was intrigued with this Invited Commentary as the rural high school I help in North Carolina lost its athletic trainer. This is great article as it highlights the risk associated with these disparities and maybe can be used to help politicians and school leaders address this issue.

Case reports are a great way to learn, whether the write-up is about some rare, uncommon condition or just a different presentation of a common problem. I would like to highlight two not-to-be-missed cases from the past quarter:

Case of Neurolymphomatosis Presenting to a Sports Medicine Clinic as Worsening Asymmetric Upper Extremity Weakness and Pain authored by Levi Harris, DO, MPH; Misty Todd, MD; and Luke Stephens, MD, MSPH. So I will admit I had to look up exactly what neurolymphomatosis was when I started to read this case. We have all likely seen many neuropathies and might become complacent with the evaluation and the work up. This case highlights the importance of having a broad differential diagnosis and is a good reminder to continuously reassess based on the data you collect.

Platelet-Poor Plasma for the Treatment of a Quadriceps Tear in a Division 1 Football Athlete authored by Ryan C. Kruse, MD, CAQSM; Elena Volfson, BA; and Jennifer Ferden, MS, ATC. There is always a lot of talk about platelet-rich plasma, but I found this article interesting with the use of platelet-poor plasma. This is an interesting case with a great review of the anatomy of the rectus femoris. There is still a lot that needs to be figured out in the world of orthobiologics and this case report can add to the body of literature.

We also have some awesome section articles that cover a variety of areas, and I would like to highlight three from the past quarter:

Equestrian Sports Safety; An Update on Safety Equipment and Event Medical Coverage authored by Sara Gould, MD; Ian R. Roy, MPH; Gabriel D. Fernada, MS; Rusty Lowe; and Cindy Y. Lin, MD, FACSM. We have published a lot of articles on event medical coverage in the past but never one that involves horses. The authors did a great job describing the safety equipment used by riders and the challenges of each discipline. The lessons and recommendations they provide can be translated and applied to many other events.

Persistent Pelvic Floor Dysfunction in Female Athletes: A Commentary on Postconservative Management authored by Silvia Giagio, PhD and Gráinne M. Donnelly. This article comes to us from some colleagues from Italy and the United Kingdom. This is a very interesting area that I am sure I have overlooked while caring for female athletes and when I read or attend lectures on this topic, I realize there is quite the knowledge gap. This is an excellent article that I think can help close the knowledge gap.

Cannabis Intoxication: a New and Evolving Concern for Sports Medicine authored by Kasey Stickler, MD; Shannon Blass Morrone, BS; Katherine Redmond, DO; Lyn O’Connell, PhD; Andrew Gilliland, MD; James Becker, MD; Adam M. Franks; and David P. Rupp, MD. This is clearly an area that needs more research and we all likely need more education about. Just because something is legal does not mean it is safe! I have had a couple of my continuity patients use THC/CBD and Delta 9 products and have substance induced mood disorders that have led to hospitalization. This will continue to be a challenge as the rules change state by state.

CSMR is ACSM’s official monthly clinical-review e-journal. Written specifically for physician and clinician members, CSMR articles provide thorough overviews of the most current sports medicine literature. ACSM physician members receive an online subscription to this journal as a member benefit.

Shawn F. Kane, MD, FACSM, is a family physician, professor in the Department of Family Medicine, and adjunct assistant professor in the Department of Exercise and Sports Science at the University of North Carolina (UNC) Chapel Hill. He received his medical degree from the Uniformed Services University of the Health Sciences and served in the U.S. Army for 27 years. He is interested in sports medicine, concussion care, veterans’ health, and primary care of patients with post-traumatic stress disorder. Dr. Kane joined ACSM in 2003 and became a fellow in 2011. He currently serves as the editor-in-chief for Current Sports Medicine Reports, on ACSM’s Clinical Sports Medicine Leadership Committee, ACSM’s Health & Fitness Summit Program Committee, and ACSM’s Program Committee. Outside of the office, Dr. Kane enjoys hanging out with his Leonbergers (big, furry, cute German Mountain dogs), as well as working out and traveling.

GSSI Pre-Conference

The Physiology of Hydration: More Than Water Alone

This session explores the physiology of hydration through an integrated lens—examining how carbohydrate, sodium, flavor, and fluid interact to influence intake, absorption, retention, and performance. We’ll review current research on fluid balance, osmotic drivers, and palatability, highlighting mechanisms that underpin voluntary intake and thermoregulation. Attendees will gain insight into individualized strategies, including sweat profiling and timing approaches, to optimize euhydration and mitigate performance decrements associated with >2% body-mass loss. Practical applications will be linked to laboratory- and field-based research, ensuring translation from bench to field. This pre-conference equips you with evidence-based tools to support athlete hydration across diverse environments and sporting contexts.
