Welcome everyone to our first issue of the Clinical Journal of Sport Medicine in 2019, and a very happy new year to all of our readers. 

This year promises to be one with an exciting and packed sporting calendar ahead. Highlights include the 2019 Rugby World Cup in Japan which takes place in September - a month also dominated by the World Athletic Championships in Doha, and the Women’s soccer World Cup in France.

On a personal note, I’m looking forward to the conclusion of the English Premier League in May and the UEFA Champion’s League final on the first of June in Madrid, Spain. I’m also looking forward to seeing how Tiger Woods gets on in the majors.

Forthcoming important events for Journal readers include the Annual Conferences of our Affiliate Societies, including the American Medical Society for Sports Medicine (AMSSM) in Houston, Texas in April, the Canadian Academy of Sports and Exercise Medicine (CASEM) in Vancouver in May, the Australasian College of Sport and Exercise Physicians (ACSEP) in Queenstown in February, and the American Osteopathic Academy of Sports Medicine (AOASM) in Austin, Texas in May.

CJSM will bring you the abstracts and poster presentations from both the AMSSM and CASEM conferences as usual, and we particularly look forward to publishing new research from our Affiliate Society members. 

We at the Journal are looking forward to bringing you a wealth of new and original research in the year ahead, which we hope will help clinicians to choose the best treatments for our patients and to lead our patients towards the best possible outcomes. In addition, we will continue to offer high-quality continuing medical education modules, together with plenty of multimedia content related to our Journal articles and the world of sport and exercise medicine in general.

A particular challenge for clinicians is the translation of research evidence into clinical practice, and we will have more to say on that topic throughout the year.

We kick off our 2019 issue with a thought-provoking Editorial by Manalac and Loffreda-Mancinelli who question the wisdom of banning headers in soccer in order to seek to prevent both acute concussion episodes and chronic traumatic encephalopathy amongst youth soccer players. The authors call for a common sense approach to the issue, taking into account cumulative training and match load, together with age-group segregation in order to mitigate these risks. I am sure that many of you will wish to contribute to the debate on this topic, and CJSM would be pleased to hear your views.

Chrisman and colleagues examine variation in head impact exposure amongst a small cohort over a 1-month period of soccer game play, comparing the quantity and magnitude of head impact exposure by sex and age level and observing outcome measures after 1 month. They found that there was variation in events, with a greater number occurring amongst older, and female, players. 

On a similar topic, Fehr and colleagues retrospectively reviewed the charts of 546 young athletes presenting with mild traumatic brain injury symptoms to a pediatric sports-based concussion clinic, and found that duration of symptoms was related to initial symptom severity, female sex, and loss of consciousness. They point out that predictors of recovery identified in their study are consistent with those identified in previous similar studies, and support the predictive value of these variables in a variety of patient populations.

Other Original Research topics this month include a systematic review of return to sports following meniscal injuries, of non-operative treatments of labral tears of the hip in adolescent athletes, and an interesting study on the association of ACTN3 R577X polymorphism with injury incidence and severity in professional football.  

Our General Review this month by Hewett and colleagues this issue is a systematic selection of key logistic regression variables for risk prediction analyses. 

We also bring you two Case Reports on the subjects of autologous leukocyte-reduced platelet rich plasma for chronic medial collateral ligament injuries of the knee, and on  overuse proximal radial head fractures in young gymnasts. 

Don’t forget to keep up-to-date with us on the CJSM blog  and on our social media channels on Twitter @CJSMonline , and FaceBook  

We hope that you’re as excited about the new research which will be coming your way in 2019 as we are. 

Best wishes, 



Christopher Hughes MBBS MSc
