Fashionably late: A characterization of late coagulopathies in rattlesnake envenomations between Fab and F(ab')2 antivenoms.

Background: Rattlesnake envenomation may lead to a multitude of clinical effects, including a late onset hemorrhage. Laboratory values such as platelets and fibrinogen are commonly used to assess the risk of developing a life-threatening bleed. To date, no specific threshold has been identified that links a lab value to the risk of bleeding.

Initial Experience with F(ab')2 Antivenom Compared with Fab Antivenom for Rattlesnake Envenomations Reported to a single poison center during 2019.

Background: There are two Food and Drug Administration (FDA)-approved antivenoms available for rattlesnake envenomations in the United States: the equine-derived F (ab')2 product sold with the brand name Anavip (F (ab')2 AV) and the ovine-derived Fab product sold with the brand name Crofab (FabAV).

Objective: To compare the clinical outcomes of rattlesnake envenomation patients treated either with FabAV or F (ab')AV or a combination of these.

Methods: This is a retrospective chart review of all human rattlesnake envenomations requiring antivenom reported to one regional poison control center in 2019.

Tweeting birds: online mentions predict future citations in ornithology.

The rapid growth of online tools to communicate scientific research raises the important question of whether online attention is associated with citations in the scholarly literature. The Altmetric Attention Score (AAS) quantifies the attention received by a scientific publication on various online platforms including news, blogs and social media. It has been advanced as a rapid way of gauging the impact of a piece of research, both in terms of potential future scholarly citations and wider online engagement.
