Direct Determination of Glyphosate and Its Metabolites in Foods of Animal Origin by Liquid Chromatography-Tandem Mass Spectrometry.

Glyphosate is the most used herbicide in agriculture. Its major metabolite is AMPA (aminomethylphosphonic acid), but N-acetyl-AMPA and N-acetylglyphosate are also metabolites of interest. For risk assessment, a general residue definition was proposed as the sum of glyphosate, AMPA, N-acetyl-glyphosate and N-acetyl-AMPA, expressed as glyphosate.

Thromboelastography Use to Guide Resuscitation and Antivenom Administration after Gaboon Viper Bite.

The Gaboon viper () is an exotic snake native to sub-Saharan Africa. Gaboon viper venom is an extremely toxic hemotoxin, causing severe coagulopathy and local tissue necrosis. These are not aggressive snakes and therefore bites involving humans are rare and there is not a substantial amount of literature documenting how to manage these injuries and resultant coagulopathies.

The Trauma Activation Review Committee: Response to Undertriage During a Period of Rapid Growth at a Level II Trauma Center.

Trauma triage criteria are constantly being refined for improved identification of severely injured patients. When errors occur, they should be tracked, and triage criteria adjusted to minimize these events. Two time periods of trauma registry data at a single rural level II trauma center were retrospectively compared to evaluate demographics, injuries, and outcomes to identify triage errors.

Situations That Preclude Routine Intraoperative Cholangiography.

Intraoperative cholangiogram (IOC) is a useful tool for surgeons to assess anatomy of the biliary tree and diagnose biliary pathology. Many surgeons utilize cholangiography in most cases in hopes of preventing ductal injuries and are deemed routine cholangiographers. There is little data on the success rate and reasons why IOC is not performed.

Coronavirus-Associated Coagulopathy After Trauma.

Coronavirus disease 2019 (COVID-19) is linked with a hypercoagulable state called COVID-19-associated coagulopathy (CAC). Due to elevated levels of factor VIII and fibrinogen as well as inflammation-linked hyperviscosity of blood, the risk for venous thromboembolism is increased in patients who have CAC. We report the case of a patient with recent COVID-19 infection and no other past medical history who presented after a motorcycle collision with left middle and distal femur fractures, who underwent retrograde intramedullary nailing, and then developed immediate massive bilateral pulmonary emboli.
