Welcome to the July issue of the Clinical Journal of Sport Medicine, our fourth issue this year.
This month we focus on the important topic of Exercise-Associated Hyponatremia (EAH) as we bring you the Consensus Statement from the Third International Exercise-Associated Hyponatremia Consensus Development Conference held in Carlsbad, California earlier this year. This Statement is an update of the Second Consensus Statement on EAH previously published in CJSM in 2008.
This latest comprehensive Consensus Statement represents the most thorough review on the topic of EAH available to date, and offers a clear summary of recommendations for practicing clinicians.
The accompanying Editorial by one of the Lead Authors of the 2015 Statement, Dr Mitchell Rosner, succinctly highlights the importance of the latest Consensus Statement in attempting to prevent deaths due to EAH which, unfortunately, still occur. The 2015 EAH Consensus Group believe that the vast majority of these deaths are entirely preventable and, as Dr Rosner points out, educating the general public involved in sports participation as to the dangers of excessive fluid consumption and recommending the safest strategy of drinking according to thirst during events are the most important public health messages arising from the Statement.
We at the Clinical Journal of Sport Medicine are proud and happy to endorse the latest Consensus Statement and to disseminate this with the aim of preventing the tragedies still too often seen as a result of over-hydration during sporting events.
Complementing the publication of the latest EAH Statement, we also bring you a podcast interview with one of the Lead Authors, Dr Tamara Hew-Butler, which can be found in our Podcast section and on the iTunes store.
There are two other EAH-related Original Research articles this month, with Scotney and Reid’s study of Body weight, serum sodium levels, and renal function in an ultra-distance mountain run, and Cairns and Hew-Butler’s manuscript on the Incidence of EAH and its association with non-osmotic stimuli of arginine vasopressin in an ultra-endurance marathon event.
We also bring you four Original Research articles on the ever-hot topic of concussion in sport, and a study by Fuller and colleagues who found that Vibration Therapy is not a useful addition to our armamentarium in promoting recovery from muscle damage following eccentric exercise.
Mohdati and colleagues present the results of their randomized trial analyzing patient-reported disease-specific quality of life outcomes at 1 and 2-years post-surgery, following 3 different anatomically positioned ACL autografts. This study, involving a total of 330 patients, showed that quality of life scores for patients with patellar tendon grafts, quadruple-stranded hamstring grafts and double-bundle grafts using hamstring tendons, increased following surgery over time but were not different at 2 years, suggesting that differences in the techniques used for ACL reconstruction amongst these patients were not important as a determinant of the outcomes measured.
Those of us looking after golfers who complain of shoulder pain and impaired performance associated with shoulder arthritis will be happy to read that those patients who return to golfing activity following a total shoulder arthroplasty generally do well in terms of both reductions in pain during activity, and in improvements in driving distances and handicap scores on return to sport.
There are two case reports, the first by Fibel and colleagues highlighting the dangers associated with intravenous fluid administration prior to sporting activity in Professional Football, and the second by Aktas and colleagues who present an interesting case where lateral pectoral nerve injury mimics cervical radiculopathy.
We are looking forward to September when we will be bringing you our exciting Thematic Issue in association with the Wilderness Medicine Society on the Care of the Wilderness and Adventure Athlete.
As ever, don't forget to check out our blog at http://www.cjsmblog.com and our social media content on Twitter (@cjsmonline) and Facebook, led by our Emerging Media Editor, Dr James MacDonald.
Finally this month, we are happy to announce that our new Associate Editor for Continuing Medical Education (CME) is Professor Holly Benjamin, based at the University of Chicago. Holly will already be well known to many of you from her past and present associations with both our affiliate Society, the American Medical Society for Sports Medicine, and with the American College of Sports Medicine. She is an accomplished educator with a strong track record of excellence in this field, and will be working with us on our forthcoming expansion of CME content. Welcome once again to our team, Holly!
Until next time, as always, with my very best wishes,
Christopher Hughes MBBS MSc
