Jellyfish are ubiquitous animals registering a high and increasing number of contacts with humans in coastal areas. These encounters result in a multitude of symptoms, ranging from mild erythema to death. This work aims to review the state-of-the-art regarding pathophysiology, diagnosis, treatment, and relevant clinical and forensic aspects of jellyfish stings. There are three major classes of jellyfish, causing various clinical scenarios. Most envenomations result in an erythematous lesion with morphological characteristics that may help identify the class of jellyfish responsible. In rare cases, the sting may result in delayed, persistent, or systemic symptoms. Lethal encounters have been described, but most of those cases happened in the Indo-Pacific region, where cubozoans, the deadliest jellyfish class, can be found. The diagnosis is mostly clinical but can be aided by dermoscopy, skin scrapings/sticky tape, confocal reflectance microscopy, immunological essays, among others. Treatment is currently based on preventing further envenomation, inactivating the venom, and alleviating local and systemic symptoms. However, the strategy used to achieve these effects remains under debate. Only one antivenom is currently used and covers merely one species (Chironex fleckeri). Other antivenoms have been produced experimentally but were not tested on human envenomation settings. The increased number of cases, especially due to climate changes, justifies further research in the study of clinical aspects of jellyfish envenoming.

This article analyses the effect of employees’ perceptions of corporate social responsibility (CSR) on job engagement, and we measure meaningfulness experienced and the role of cross-level sensemaking factors, such as the bottom-up approach and calling orientation. Drawing on qualitative data, collected among workers that had CSR implemented in their companies, our findings suggest that both calling orientation and meaningfulness influence the positive impact of the CSR perceptions on job engagement through sequential mediation. The calling orientation has an important role in this relationship because meaningfulness alone does not influence the relationship between CSR and job engagement. Additionally, employees’ perceptions of CSR positively influence job engagement. Furthermore, our research indicates that the meaningfulness experienced by workers increases in the presence of a bottom-up approach in what concerns the definition and implementation of CSR actions of the company. Overall, this research expands our understanding of how people find meaningfulness through individual experiences of CSR.
