Interassociation Consensus Statement on Cardiovascular Care of College Student-Athletes

Interassociation Consensus Statement on Cardiovascular Care of College Student-Athletes

Hainline B, Drezner JA, Baggish A, Harmon KG, Emery MS, Myerburg RJ, Sanchez E, Molossi S, Parsons JT, Thompson PD. J Am Coll Cardiol. 2016 Apr 7. pii: S0735-1097(16)32406-8. doi: 10.1016/j.jacc.2016.03.527. [Epub ahead of print]

The National Collegiate Athletic Association (NCAA) convened a multidisciplinary task force to address cardiovascular care in the collegiate student-athlete. “The purpose of the task force was to discuss and evaluate cardiovascular concerns in collegiate student-athletes and to develop an interassociation consensus statement and recommendations for the future. The primary focus was sudden cardiac death and the utility of screening with or without electrocardiogram (not including echocardiogram).” The document has sections regarding the pre-participation evaluation and recognition and response to cardiac arrest. Furthermore, there’s also sections related to cardiovascular risk in collegiate student-athletes, evidence evaluating the efficacy of pre-participation screening for detection of cardiovascular risk, ECG as a screening tool for SCD risk prediction, regional referral centers for evaluation of athletes suspected or known to have a cardiovascular problem, and cardiac research initiatives.

Should We Drop the Vertical Drop Jump?

The Vertical Drop Jump is a Poor Screening Test for ACL Injuries in Female Elite Soccer and Handball Players

Krosshaug T, Steffen K, Kristianslund E, Nilstad A, Mok KM, Myklebust G, Andersen TE, Holme I, Engebretsen L, & Bahr.  Am J Sports Med. 2016; 44: 874-883. DOI: 10.1177/0363546515625048

Take Home Message: Performance on the vertical drop jump landing task was not found to be associated with anterior cruciate ligament injury risk in a group of female handball and soccer athletes. 

We have had quite a few posts on Sports Med Res surrounding the short- and long-term effects of anterior cruciate ligament (ACL) injury.  However, we still need to determine how to best identify who may be at risk for ACL injury so that we can optimize prevention strategies.  Many try to screen athletes with the drop jump landing task, but it remains unclear whether this test is predictive of subsequent injury.  Therefore, this study’s authors aimed to prospectively evaluate the accuracy of the drop jump landing task in predicting ACL injury.

Patient-Reported Outcome Measures Are Associated to Biochemical Markers

Physical Activity Levels and Quality of Life Relate to Collagen Turnover and Inflammation Changes After Running

Cattano NM, Driban JB, Barbe MF, Tierney R, Amin M, Sitler MR.J Orthop Res. 2016: ahead of print

Take Home Message: Poor scores on the Knee Osteoarthritis Outcome Score and Tegner Activity Scale may be associated with elevated biomarker concentration levels that reflect collagen turnover.

Understanding the risk factors for early return to play following a musculoskeletal injury is important due to the increased chance for developing chronic injuries or never returning back to pre-injury activity levels. One potential solution to obtain a more definitive gauge on readiness to return is to measure biochemical markers (biomarkers). Therefore, the authors measured 22 athletes (11 with a history of ACL and/or meniscal surgery and 11 healthy matched controls) blood serum before and after a 30-minute set paced run on a treadmill to assess if pre-exercise patient-reported outcomes are related with biomarker changes of collagen turnover, inflammation, and bone/cartilage degeneration.

Smoking, Dyspnea and COPD may Predict Complications Following ACL Reconstruction

Risk factors for short-term complications of anterior cruciate ligament reconstruction in the United States.

Cvetanovich GL, Chalmers PN, Verma NN, Cole BJ, and Bach BR. Am J Sports Med. 2016. [Epub Ahead of Print].

Take Home Message: Complications following anterior cruciate ligament reconstruction are rare (1.3%). Patients who smoke, have a history of chronic obstructive pulmonary disease, or dyspnea have a greater risk of complications than those that do not.

While anterior cruciate ligament (ACL) reconstruction is a common surgical procedure there is little known about risk factors for post-operative complications. Therefore, Cvetanovich completed a cohort study to determine the incidence of 30-day complications and risk factors for complications after ACL reconstruction.

Younger Patients or Those with a Meniscal Tear are More Likely to have ACL Surgery

Incidence of and Factors Associated With the Decision to Undergo Anterior Cruciate Ligament Reconstruction 1 to 10 Years After Injury

Sanders TL, Kremers HM, Bryan AJ, Kremers WK, Levy BA, Dahm DL, Stuart MJ, & Krych AJ.  Am J Sports Med. Published Online First: February 29, 2016; DOI: 10.1177/0363546516630751

Take Home Message: A patient who is young or has a meniscal injury is more likely to have an anterior cruciate ligament surgery (either early or delayed). 

We have had quite a few posts on Sports Med Res surrounding anterior cruciate ligament (ACL) tears and the subsequent management of this injury (see a sample below).  However, we still need to determine how to identify who may respond well to conservative treatment.  Therefore, the authors aimed to define the rate of delayed ACL reconstructions and to identify predictors of early or delayed ACL reconstruction.

Psychological Factors Regarding Recovery May Influence Acute and Overuse Injury Risk

Injury Risk Is Increased By Changes in Perceived Recovery of Team Sports Players

van der Does HT, Brinke MS, Ardi Otter RT, Visscher C. Clin J Sport Med. 2016: ahead of print

Take Home Message: A reduced perception of recovery during a season may increase the risk of acute and overuse injury.

Psychological factors such as personality characteristics and history of stressors may be factors that influence injury occurrence. However, there is little research focusing on the role of psychological factors in injury. Therefore, the authors investigated whether changes in perceived stress and recovery over the course of a season are risk factors for acute and overuse injuries among 86 (58 males, 28 females) athletes participating in a team sport (26 basketball, 38 volleyball, 22 korfball).

Previous Participation in Collision Sports is Related to a Decreased Quality of Life

Current health-related quality of life in former national athletic association division I collision athletes compared with contact and limited-contact athletes.

Simon J, Docherty CL. J Athl Training. 2016. 51(4). Epub Ahead of Print

Take Home Message: Former collegiate athletes who participated in collision sports (primarily football) reported lower quality of life when compared to contact or limited contact athletes.

Sports participation relates to both positive (e.g., reduced cardiovascular disease) and negative (e.g., pain, psychological concerns) long-term outcomes. Clarifying the relationship between sport participation and long-term quality of life can help clinicians understand how to help athletes transition into retirement and better educate athletes with regards to long-term outcomes after injury. Therefore, Simon and Docherty completed a cross-sectional study to measure health-related quality of life among former NCAA Division 1 collision, contact and limited-contact athletes.
