Measuring biodiversity from DNA in the air.

The crisis of declining biodiversity exceeds our current ability to monitor changes in ecosystems. Rapid terrestrial biomonitoring approaches are essential to quantify the causes and consequences of global change. Environmental DNA has revolutionized aquatic ecology, permitting population monitoring and remote diversity assessments matching or outperforming conventional methods of community sampling.

Frequency of specific osteopathic manipulative treatment modalities used by candidates while taking COMLEX-USA Level 2-PE.

Context: As one of the key measures of clinical skills assessment, the Comprehensive Osteopathic Medical Licensing Examination-USA Level 2-Performance Evaluation (COMLEX-USA Level 2-PE) is used to rate candidates' performance of osteopathic manipulative treatment (OMT).

Objective: To evaluate the frequency of specific OMT modalities used by COMLEX-USA Level 2-PE candidates and to report frequent use on the basis of clinical presentation.

Methods: With enhanced scoring procedures in place, OMT physician-examiners identified and documented specific OMT techniques that were performed by candidates at the 28 colleges of osteopathic medicine and branch campuses that had eligible students at that time.

Relationship between standardized patient checklist item accuracy and performing arts experience.

Introduction: : It is not known whether a Standardized Patient's (SP's) performing arts background could affect his or her accuracy in recording candidate performance on a high-stakes clinical skills examination, such as the Comprehensive Osteopathic Medical Licensing Examination Level 2 Performance Evaluation. The purpose of this study is to investigate the differences in recording accuracy of history and physical checklist items between SPs who identify themselves as performing artists and SPs with no performance arts experience.

Methods: : Forty SPs identified themselves as being performing artists or nonperforming artists.

Five-year summary of COMLEX-USA level 2-PE examinee performance and survey data.

The authors present data on examination format and examinee demographics, performance, and survey results for the Comprehensive Osteopathic Medical Licensing Examination-USA Level 2-Performance Evaluation (COMLEX-USA Level 2-PE) from the first five testing cycles (2004-2005 to 2008-2009). First-time examinees in the 2004-2005 testing cycle had a pass rate of 96.1%, compared with a pass rate of 94.
