False positive urine amphetamine immunoassay due to solriamfetol.

Solriamfetol is a schedule IV-controlled substance used to treat excessive daytime sleepiness resulting from narcolepsy or obstructive sleep apnea. We present a patient prescribed solriamfetol who tested positive for amphetamines on a routine urinary toxicology screen despite patient denial of illicit drug use, raising the possibility of a false positive amphetamine screen. Spiking studies were performed on negative urine, and different concentrations of solriamfetol drug on 2 different amphetamine assays: the commonly used Beckman Emit® II Plus Amphetamines Assay, and the Citrine™ Triple Quad™ MS/MS Systems.

Divergent Rabies Virus Variant of Probable Bat Origin in 2 Gray Foxes, New Mexico, USA.

In the Western Hemisphere, bat-associated rabies viruses (RABVs) have established independent transmission cycles in multiple mammal hosts, forming genetically distinct lineages. In New Mexico, USA, skunks, bats, and gray foxes are rabies reservoir hosts and represent a public health risk because of encounters with humans. During 2015 and 2019, two previously undescribed RABVs were detected in 2 gray foxes (Urocyon cinereoargenteus) in Lincoln County, New Mexico.

Is transperineal prostate biopsy more accurate than transrectal biopsy in determining final Gleason score and clinical risk category? A comparative analysis.

Objectives: To assess the degree of upgrading and increase in clinical risk category of transperineal template biopsy (TTB) compared with transrectal ultrasonography-guided prostate biopsy (TRUSB). Upgrading of TRUSB Gleason grade and sum after radical prostatectomy (RP) is well recognised. TTB may offer a more thorough mapping of the prostate than TRUSB, as well as a more accurate assessment of the tumour.
