Perceptions and Prevalence of Anxiolytic Medication Usage for Performance Enhancement Among Musicians.

Objective: While anecdotal reports of the use of performance-enhancing medications to curb anxiety in performing artists abound, there has been no research to date assessing the prevalence of usage and attitudes towards use amongst the artists themselves. The objective of this study was to evaluate the perceptions, acquisition, and use of potentially performance-enhancing medications (benzodiazepines, beta-blockers, and cannabinoids) in the performing artist community to clarify the use of these medications to improve patient counseling and patient safety.

Design: Cross-sectional survey.

Treatment Options for Patellofemoral Arthritis.

To present a synthesis of recent literature regarding the treatment of patellofemoral arthritis RECENT FINDINGS: Risk factors of PFJ OA include patella malalignment or maltracking, injury to supportive structures including the MPFL, dysfunction of hamstring and quadriceps coordination, lower limb alignment, trochlear dysplasia, patellar trauma, or ACL surgery. Special physical exam maneuvers include patellar grind test, apprehension test, and lateral patellar tilt angle. Radiographs that should be obtained first-line include weight bearing bilateral AP, lateral, and Merchant views.

Iron deficiency in athletes: A narrative review.

Iron deficiency is a concern for athletes due to potential for performance impairments attributed to lower iron status with, or without, accompanying anemia. Despite the high interest in the topic for endurance athletes and medical providers who care for this population, the evaluation and management of athletes with iron deficiency is still evolving, particularly in relation to iron deficiency non-anemia (IDNA). This narrative review presents causes of iron deficiency in the athlete, clinical presentation, differential diagnoses, diagnostic evaluation, and proposed strategies for treatment.

Narrative Review - Knee Pain in the Pediatric Athlete.

Purpose Of Review: This review article seeks to highlight common youth athlete knee conditions due to overuse or trauma and elucidate differences from the adult populations.

Recent Findings: Overuse conditions presented include apophysitis, osteochondritis dissecans plica syndrome, and discoid meniscus. Traumatic conditions presented include patellar instability, patellar sleeve fracture, and patellofemoral osteochondral fractures.

Narrative: Review of Anterior Knee Pain Differential Diagnosis (Other than Patellofemoral Pain).

Purpose Of Review: This review presents a framework for constructing a differential diagnosis for chronic anterior knee pain associated with overuse other than patellofemoral pain. Traumatic, systemic, and pediatric injuries will not be covered.

Recent Findings: From superficial to deep, the anterior knee can be conceptually organized into four layers: (1) soft tissue, (2) extensor mechanism, (3) intracapsular/extrasynovial, and (4) intra-articular.

Gait features for discriminating between mobility-limiting musculoskeletal disorders: Lumbar spinal stenosis and knee osteoarthritis.

Background: Functional ambulation limitations are features of lumbar spinal stenosis (LSS) and knee osteoarthritis (OA). With numerous validated walking assessment protocols and a vast number of spatiotemporal gait parameters available from sensor-based assessment, there is a critical need for selection of appropriate test protocols and variables for research and clinical applications.

Research Question: In patients with knee OA and LSS, what are the best sensor-derived gait parameters and the most suitable clinical walking test to discriminate between these patient populations and controls?

Methods: We collected foot-mounted inertial measurement unit (IMU) data during three walking tests (fast-paced walk test-FPWT, 6-min walk test- 6MWT, self-paced walk test - SPWT) for subjects with LSS, knee OA and matched controls (N = 10 for each group).

Utilizing Digital Health Technologies for Patient Education in Lifestyle Medicine.

Technology has redefined the way patients and providers communicate and obtain health information. The realm of digital health encompasses a diverse set of technologies, including mobile health, health information technology, wearable devices, telehealth and telemedicine, and personalized medicine. These technologies have begun to improve care delivery without the traditional constraints of distance, location, and time.

Venous Thromboembolism in Upper Extremity Fractures.

Background: Venous thromboembolism (VTE) has been studied in lower extremity fractures but little is known of its relation with upper extremity (UE) fractures. As an often overlooked but serious complication, VTE may compromise patient outcomes.

Methods: Using data on inpatients (aged ≥ 18 years) at a level-I trauma center and patients in the National Surgical Quality Improvement Program database who sustained UE fractures (clavicle, humerus, or radius/ulna) and VTE in the same hospitalization between 2007 and 2014, the authors analyzed data on demographic characteristics, fracture type, VTE location (pulmonary embolism, lower extremity, or UE), VTE onset, polytrauma, operative or nonoperative management, comorbidities, and mortality.

Sacral-Alar-Iliac Fixation in Children with Neuromuscular Scoliosis: Minimum 5-Year Follow-Up.

Objective: To investigate the 5-year outcomes of children with neuromuscular scoliosis treated with sacral-alar-iliac screws.

Methods: We reviewed clinical and radiographic records of patients aged ≤18 years treated by 1 pediatric orthopedic surgeon for neuromuscular scoliosis with spinal fusion using sacral-alar-iliac pelvic anchors. Thirty-eight patients with a minimum 5-year radiographic follow-up (mean, 6.

Children with Warts: A Retrospective Study in an Outpatient Setting.

Background: The purpose is to investigate the demographics and course of common warts in children in an outpatient setting.

Methods: A retrospective medical chart review and telephone survey study were completed on an outpatient cohort of children (0-17 yrs) with a clinical diagnosis of warts at a single-center, university-based pediatric dermatology practice. The main outcome measures included management, time to resolution, and associated factors of warts in children.

Convection-enhanced delivery of targeted quantum dot-immunoliposome hybrid nanoparticles to intracranial brain tumor models.

Aim: The aim of this work is to evaluate combining targeting strategy and convection-enhanced delivery in brain tumor models by imaging quantum dot-immunoliposome hybrid nanoparticles.

Materials & Methods: An EGF receptor-targeted, quantum dot-immunoliposome hybrid nanoparticle (QD-IL) was synthesized. In vitro uptake was measured by flow cytometry and intracellular localization was imaged by confocal microscopy.
