Inter-individual variability in equine antibody responses to African snake venoms follows heavy-tailed distributions with implications for antivenom production

  Inter-individual variability in equine antibody responses to African snake venoms follows heavy-tailed distributions with implications for antivenom production Abstract Variability in the antibody response of horses used for snake antivenom manufacture is well recognized, yet its statistical structure and implications for industrial productivity remain poorly characterized. In this study, we quantified antivenom antibody titers by ELISA in a cohort of 14 horses immunized with venoms from the clinically most important snakes in sub-Saharan Africa. To integrate antibody levels with plasma availability, we calculated the Cumulative Plasma Productivity (CPP) by converting individual plasma volumes into titer-corrected equivalents and sequentially pooling these volumes according to their corrected contribution. Distributional analysis revealed right-skewed, heavy-tailed patterns better approximated by a log-normal model than by a strict Pareto (power-law) form, with approximately 20–3...

Post-traumatic phenomena secondary to snakebite envenomation: a psychiatric clinical perspective

Abstract

Snakebite envenomation represents a major global public health concern. Beyond physical outcomes suffered by the patients, studies have documented significant psychiatric and psychological sequelae. Consequently, there is an urgent need to document and intervene the psychiatric/psychological sequelae of snakebite envenomation alongside the clinical assessment. This work presents a narrative review of the psychiatric consequences described in snakebites in several settings. In addition, it addresses the screening/detection actions focused on Post-Traumatic Phenomena from a psychiatric perspective that are useful in general and specialized medicine settings in snakebite envenomation.
