Long-Term Kidney Outcomes Following Snake Envenomation: The Role of Snakebite-Related Acute Kidney Injury in a Nationwide Korean Cohort

  Long-Term Kidney Outcomes Following Snake Envenomation: The Role of Snakebite-Related Acute Kidney Injury in a Nationwide Korean Cohort Abstract Long-term renal outcomes following snake envenomation may vary across regions, yet remain poorly characterized in South Korea. We investigated the long-term risk of chronic kidney disease (CKD) following snake envenomation and snakebite-related acute kidney injury (AKI). This nationwide population-based cohort study used data from the Korean National Health Information Database (2012–2023). We matched 729 adults hospitalized for snake envenomation who received antivenom to 2916 individuals without snake envenomation (1:4). Using a 1-year landmark design, we assessed incident CKD with Cox proportional hazards models and Kaplan–Meier analysis. CKD occurred in 48 patients with snake envenomation and in 156 controls, with incidence rates of 7.16 and 5.59 per 1000 person-years, respectively. Snake envenomation was not significantly associated...

Spiders (Arachnida: Araneae) of a wildlife and cattle savanna ranch in South-Western Zimbabwe

In order to contribute to spider diversity distribution records within Zimbabwe, spiders were sampled at a mixed wildlife and cattle ranch using pitfall traps and sweep-netting. Sampling was conducted from June 2017 to April 2018. A total of 2328 spiders representing 25 families, 94 genera, and 166 species were recorded. The most species-rich families were Salticidae (33 spp.), followed by the Gnaphosidae (28 spp.) and Lycosidae (20 spp.), while eight families were represented by a single species. Pitfall traps accounted for 1857 individuals overall, with the ground-dwelling fauna dominated by Stenaelurillus guttiger (37.86% of the total abundance). Sweep-nets accounted for 471 individuals overall, with the grass-dwelling fauna dominated by Thyene thyenioides (15.29% of the total abundance). The most abundant functional group was the free-living ground-dwellers (n = 1809, 77.71%), followed by free-living plant-dwellers (n = 266, 11.43%) and orb-web builders (n = 186,
7.98%). The current study contributes to the knowledge of a megadiverse group of predatory arthropods in the region.

Conservation implications: Sampling and monitoring of rangelands is essential, as the former aids in the identification of new species not previously recorded, as well as increasing knowledge on the distribution of spider species, which if not adequately conserved could face significant threats to their survival even before their documentation.
