Malpractice Liability Exposure and the Sports Medicine Team Physician: Caring for Professional Athletes in the National Football League, Major League Baseball, and National Hockey League.

Background: Orthopaedic surgeons play a critical role in ensuring the health and safety of professional athletes. Despite the privilege of treating elite athletes, there exists great financial exposure to individual physicians in the event of a malpractice lawsuit.

Hypothesis/purpose: The purpose of this study was to evaluate and model malpractice liability exposure of the sports medicine surgeon caring for athletes in the National Football League (NFL), Major League Baseball (MLB), and National Hockey League (NHL) with respect to player position and additional supplemental malpractice insurance needs.

Early midlife ovarian removal is associated with lower posterior hippocampal function.

Introduction: Women with early bilateral salpingo-oophorectomy (BSO) have greater Alzheimer's disease (AD) risk than women with spontaneous menopause (SM), but the pathway toward this risk is understudied. Considering associative memory deficits may reflect early signs of AD, we studied how BSO affected brain activity underlying associative memory.

Methods: Early midlife women with BSO (with and without 17β-estradiol therapy [ET]) and age-matched controls (AMCs) with intact ovaries completed a face-name associative memory task during functional magnetic resonance imaging.

Environmental concentrations of antibiotics induced polymyxin B tolerance in Aeromonas hydrophila.

Polymyxin B is one of the last lines of defense in infections caused by multidrug-resistant Gram-negative bacteria. Aeromonas hydrophila are important fish pathogens and the occurrence of polymyxin B-resistant A. hydrophila isolates is increasing.

CALR frameshift mutation detection in myeloproliferative neoplasms by microfluidic chip analysis.

Background: CALR mutation analysis is routinely used to diagnose BCR/ABL1-negative myeloproliferative neoplasms. The 2 most common CALR mutations are a 52-base pair (bp) deletion and a 5-bp insertion, which account for approximately 85% of cases.

Methods: To evaluate our new microfluidic chip assay, we tested CALR mutant and wild-type specimens that were previously analyzed using conventional methods at a reference laboratory.

Manual Dexterity in Open-Water Wetsuited Swimmers: A Cohort Crossover Study.

Purpose: Laboratory studies have demonstrated that manual dexterity decreases with increasing cold, which may adversely affect performance. Dexterity may be impaired by cooling of the hand, cooling of the lower motor neurons, and cognitive impairment. Wetsuits are commonly used in open-water swimming and are mandated in some situations.
