Sonographic Screening of Distance Runners for the Development of Future Achilles and Patellar Tendon Pain.

Objective: The 2 primary aims of this study were to identify ultrasonographic tendon abnormalities in asymptomatic runners and to examine the likelihood of developing pain in runners with ultrasound abnormalities compared with those without abnormalities.

Design: Longitudinal, prospective cohort study.

Setting: 2019 Salt Lake City Marathon.

Validity of a Sham Dry Needling Technique on a Healthy Population.

Background: Various methods of sham procedures have been used in controlled trials evaluating dry needling efficacy although few have performed validation studies of the sham procedure.

Hypothesis/purpose: The purpose of this study was to examine the validity of a sham dry needling technique on healthy, active subjects.

Study Design: Validation study.

Postrace Dry Needling Does Not Reduce Subsequent Soreness and Cramping-A Randomized Controlled Trial.

Objective: To identify whether a single session of postrace dry needling can decrease postrace soreness and quantity of postrace leg cramps in half-marathon and full-marathon runners.

Design: Single-blind, prospective, randomized, controlled trial.

Setting: Finish line of 2018 Salt Lake City Marathon & Half-Marathon.

Hand hygiene noncompliance and the cost of hospital-acquired methicillin-resistant Staphylococcus aureus infection.

Background: Hand hygiene noncompliance is a major cause of nosocomial infection. Nosocomial infection cost data exist, but the effect of hand hygiene noncompliance is unknown.

Objective: To estimate methicillin-resistant Staphylococcus aureus (MRSA)-related cost of an incident of hand hygiene noncompliance by a healthcare worker during patient care.

Carboxylation and esterification of functionalized arylcopper reagents.

Functionalized arylcopper reagents have been produced in good yields at 25 degrees C from activated copper and the corresponding functionalized aryl iodides without the need of traditional organolithium or Grignard precursors. These organocopper compounds will undergo carboxylation with CO(2) to form the corresponding copper benzoates. In turn, these salts can be acidified to produce the functionalized aryl acids or treated with appropriate alkyl halides in the presence of a dipolar aprotic solvent to generate the corresponding aryl esters.
