Amino Acid Supplementation May Help Prevent Muscle Wasting After Orthopedic Surgery, but Additional Studies Are Warranted: A Systematic Review of Randomized Clinical Trials.

Essential amino acid (EAA) supplementation, including conditionally essential amino acid (CEAA) and branched-chain amino acids (BCAA) supplementation, has been suggested as a mechanism to optimize patient outcomes by counteracting the atrophy associated with orthopedic procedures. We sought to investigate the effect of EAA supplementation in the perioperative period on patients undergoing orthopedic and spine surgery, specifically whether it is associated with (1) reductions in postoperative muscle atrophy and (2) improved postoperative function including range of motion, strength, and mobility. We conducted a systematic review of the literature.

Treatment of Hip and Knee Periprosthetic Joint Infection Requires Extensive Administrative Work.

Background: Treatment of periprosthetic joint infections (PJIs) typically requires more resource utilization than primary total joint arthroplasty. This study quantifies the amount of time spent in the electronic medical record (EMR) for patients who have PJI requiring surgical intervention.

Methods: A retrospective analysis of EMR activity for 165 hip and knee PJIs was performed to capture work during the preoperative and postoperative time periods.

Risk Stratification of Acute Invasive Fungal Rhinosinusitis in Patients With Hematologic Pathology.

Objective: The purpose of this study is to identify objective perioperative diagnostic factors for acute invasive fungal rhinosinusitis (AIFS) to create a diagnostic scoring system using objective criteria.

Methods: Retrospective case-control study performed at an academic, tertiary care center. Biopsy-proven cases of AIFS identified from pathology records (2015-2019) were compared to patients the otolaryngology service was consulted to "Rule out AIFS" in the year 2019, only including those with underlying hematologic malignancy.

Postoperative and 1-Year Functional Outcomes After Free Flap Surgery Among Patients 80 Years or Older.

Objective: To evaluate the postoperative and 1-year functional outcomes after free flap surgery among patients ≥80 years old.

Study Design: Retrospective chart review.

Setting: Single tertiary care center.

A Review of Periprosthetic Tibial Fractures: Diagnosis and Treatment.

Periprosthetic fracture occurring during or after total knee arthroplasty is a rare injury. Literature concerning periprosthetic tibial factures is sparse, and there is limited guidance for evidence-based management. This review aims to provide readers with an overview of the epidemiology, risk factors, and classification of these fractures.

Electronic Medical Record Audit Time Logs as a Measure of Preoperative Work Before Total Joint Arthroplasty.

Background: In order to achieve rapid recovery total joint arthroplasty, surgeons and their teams are spending more time in the weeks before surgery to prepare patients. This study aims to quantify total knee and hip prearthroplasty work using retrospective electronic medical record (EMR) activity audit log analysis.

Methods: EMR activity in 100 elective knee and 100 elective hip arthroplasty cases was performed using audit logs.

How long after maximal physical exertion should baseline computerized neurocognitive testing and symptom assessment be administered?

: Prior research suggests maximal physical exertion (MPE) may negatively affect the reliability and validity of computerized neurocognitive testing (CNT); the purpose of this study was to identify aclinically relevant recovery interval following MPE for the administration of baseline CNT.: Random-crossover.: Thirty (M = 21.

Establishing Test-Retest Reliability and Reliable Change for the King-Devick Test in High School Athletes.

Objective: To establish test-retest reliability in nonconcussed high school athletes and compare absolute change, reliable change indices (RCIs), and minimal detectable change (MDC) methods for classifying impairment after sport-related concussion.

Design: Prospective, repeated measures.

Setting: High schools from the Midwest and Central regions of the United States.

Preliminary Study of Fear of Re-Injury following Sport-Related Concussion in High School Athletes.

The influence of fear of re-injury that this variable has on recovery outcomes following sports-related concussion remains unknown. We examined changes in fear of re-injury throughout concussion recovery, and compared changes in neurocognitive, symptom, vestibular/ocular motor, and recovery time outcomes between concussed adolescent athletes who endorsed high and low fear of re-injury. Individuals with high fear of re-injury were more symptomatic and more likely to exhibit vestibular/ocular motor symptoms over clinical cutoffs than those with low fear of re-injury.

Motion Sickness Susceptibility and Baseline Vestibular and Ocular-Motor Performance in Adolescent Athletes.

Context: High school athletes with a history of motion sickness susceptibility exhibit higher baseline vestibular and ocular-motor scores than those without a history of motion sickness susceptibility.

Objective: To examine the effects of motion sickness susceptibility on baseline vestibular and ocular-motor functioning, neurocognitive performance, and symptom scores.

Design: Cross-sectional study.

Prospective Changes in Vestibular and Ocular Motor Impairment After Concussion.

Background And Purpose: The utility of prospective changes on the Vestibular/Ocular Motor Screening (VOMS) assessment are unknown, and 2 methods of scoring are published in the literature. Total scores are the total symptom scores for each VOMS component, and change scores are the difference between the pretest total symptom score and component total symptom scores. This study documented prospective changes in vestibular and ocular motor impairments and symptoms in high school athletes with concussion using the total and change scoring methods and compared the percentage of scores over clinical cutoffs using the total and change scoring methods for the VOMS.
