Physiological Monitoring Detected Changes During Women's Soccer Anterior Cruciate Ligament Injury.

A growing number of studies utilizing wearable technologies are examining the influence of the autonomic nervous system (ANS) on intense training, recovery, and injury risk. Exercise biometric (EB) data were collected on collegiate, female soccer players during a preseason camp. One player sustained an anterior cruciate ligament (ACL) injury.

Novel repair of a quadriceps tendon rupture after a total knee arthroplasty using gracilis and semitendinosus autografts.

Background: Multiple techniques have been described for repair of quadriceps tendon rupture after total knee arthroplasty (TKA) with unsatisfactory outcomes. We present a novel technique for repair using hamstring tendon autografts.

Methods: A 54 year-old morbidly obese patient presented five months after quadriceps tendon rupture.

The Mortality of Periviable and Extremely Premature Infants and Their Impact on the Overall Neonatal Mortality Rate.

To investigate mortality in periviable neonates ≤23 weeks gestational age and calculate its impact on overall neonatal mortality rate over a 12-year period (1998-2009). Verify if periviable mortality decreased in the period (2010-2015). Retrospective review.

A Case Report of Acute Exertional Compartment Syndrome with Peroneal Nerve Palsy in an Adolescent Athlete.

Introduction: Acute following a chronic exertional compartment syndrome (CECS) is a known but uncommonly encountered complication of sports activity and its physiologic profile remains unclear to date. Failure to recognize and promptly treat this condition can lead to disastrous sequelae.

Case Report: We present the case of a 13-year-old lacrosse player with a history of CECS who developed unprovoked acute compartment syndrome.

Risk factors associated with ACL registry compliance: can we predict who will follow-up?

Purpose: The purpose of this study was to determine patient factors that influence patient compliance to fill out anterior cruciate ligament reconstruction (ACLR) registry forms.

Methods: Patients prospectively enrolled in the ACLR registry at a single institution were retrospectively reviewed. Patients who were followed up for at least 6 months were included.

American Football Players in Preseason Training at Risk of Acute Kidney Injury Without Signs of Rhabdomyolysis.

Objective: This study was designed to identify changes in blood biomarkers that would indicate excessive muscle breakdown during the initial 10 days of preseason training in collegiate American football players and subsequently increase their risk of acute kidney injury (AKI).

Design: Prospective cohort study.

Setting: Preseason, heat acclimatization period.

Colored Glasses to Mitigate Photophobia Symptoms Posttraumatic Brain Injury.

Context:   After a concussion or mild traumatic brain injury (mTBI), patients often suffer from light sensitivity, or photophobia, which contributes to decreased quality of life post-mTBI. Whereas sunglasses may provide some relief from photophobia, they are not practical indoors or in low light. A light-mitigation strategy can be easily used indoors as needed to optimize the relief.

Lack of eye discipline during headers in high school girls soccer: A possible mechanism for increased concussion rates.

The sport of soccer is the fastest growing and most popular sport worldwide. With this growth and popularity, attention needs to be given to this athletic population. Sports related concussions is a topic that has gained attention both in the media and by governmental organizations, with growing initiatives in diagnosis, prevention and treatment.

Vision training methods for sports concussion mitigation and management.

There is emerging evidence supporting the use vision training, including light board training tools, as a concussion baseline and neuro-diagnostic tool and potentially as a supportive component to concussion prevention strategies. This paper is focused on providing detailed methods for select vision training tools and reporting normative data for comparison when vision training is a part of a sports management program. The overall program includes standard vision training methods including tachistoscope, Brock's string, and strobe glasses, as well as specialized light board training algorithms.

Effects of postural control manipulation on visuomotor training performance: comparative data in healthy athletes.

Purpose/background: Visuomotor ability is an important parameter for neurologic function and effective sport performance. Adding a balance challenge during a structured eye-hand coordination task, such as hitting lights on a light board (Dynavision™), has not been previously reported. Using Division I football players, the aim of this study was to determine normative data on a dual-task performance regimen combining a visuomotor light board task with a balance task.

"Retrograde technique" for drilling the femoral tunnel in an anterior cruciate ligament reconstruction.

Recent literature has led some surgeons to drill the femoral tunnel in an anterior cruciate ligament reconstruction through an accessory anteromedial portal. Several techniques have been reported for the safe, effective drilling of the femoral tunnel by this approach. This technical note presents a new "retrograde technique" in which all instruments are passed independently into the notch and across the medial compartment.

Controlled cardiac reoxygenation does not improve myocardial function following global myocardial ischemia.

Background: It has been shown that abrupt re-exposure of ischemic myocardium to oxygen can lead to increased peroxidative damage to myocytes (oxygen paradox). Controlled cardiac reoxygenation, as an adjunct to substrate-enhanced cardioplegia, has been shown to improve myocardial function and limit reperfusion injury when utilizing standardized hyperoxic cardiopulmonary bypass (CPB). The objective of our study was to evaluate the effect of controlled reoxygenation on myocardial function following global ischemia employing normoxic CPB.

Off-pump versus on-pump coronary artery bypass surgery: does the pump influence outcome?

Background: This study assessed hospitalization outcome differences for patients undergoing off-pump coronary artery bypass (OPCAB) grafting compared with patients having coronary artery bypass grafting with cardiopulmonary bypass.

Study Design: We conducted a nested case-control study from an 8-year, hospitalization cohort (n = 7,905) in which the data were collected prospectively. Inclusion criteria included a coronary artery bypass graft only and age greater than 18 years.

Correlation of the change in the International Normalized Ratio and decreasing the Coumadin dosage following total joint arthroplasty.

This retrospective pilot study determined whether a change in the daily International Normalized Ratio (INR) correlates with a decrease in Coumadin (DuPont Pharma, Wilmington, Del) dosage. Four hundred seventeen patients yielded 1167 pairs of INR values and Coumadin doses. An increase in INR > 0.
