Abstract
Our study investigated the embryo-ototoxic effects of deodorant2 (DA2) on zebrafish embryos, which serve as valuable model organisms due to genetic and physiological similarities to humans. We focused on understanding DA2's impact on zebrafish hair cells, which are vital for sensory perception and balance regulation. DA2, provided by the Ministry of Environment, Republic of Korea, was used at 460 μg/mL in dimethyl sulfoxide (DMSO), with a 0.43% DMSO solvent control group. Three experiments, each using 10 zebrafish specimens from each group, showed an initial 13% hair cell count reduction in the DA2-exposed group. Subsequent experiments demonstrated reductions of 37% and 22%, each with one mortality case. Statistical analysis revealed a significant 24% hair cell count reduction in the DA2-exposed group. We also assessed DA2's impact on zebrafish behavior. Although not statistically significant, differences in distances traveled (0.33-0.39, 95% confidence interval: -0.46-1.1, p = 0.2033) and latencies (-0.016-0.018, 95% confidence interval: -0.052-0.021, p = 0.1917) hinted at negative effects. These results highlight DA2's ototoxic properties affecting zebrafish auditory systems and behavior. Further investigation into DA2's effects on aquatic organisms and potential mitigation strategies are essential. These findings contribute to understanding DA2's safety profile, benefiting aquatic ecosystems and human health assessments.

Abstract
BACKGROUND Totally endoscopic ear surgery is a novel method of conducting otological surgery. Hierarchical task analysis and the systematic human error reduction and prediction approach ('SHERPA') are valuable tools that can effectively deconstruct the technical and non-technical skills required to successfully complete a surgical procedure. METHODS Twenty-five endoscopic tragal cartilage tympanoplasties were observed, to identify the tasks and subtasks required for completion of totally endoscopic tragal cartilage tympanoplasty. The systematic human error reduction and prediction approach was used to identify the potential risks and methods, to reduce or remediate these risks. RESULTS A hierarchical task analysis was performed, identifying 8 tasks and 50 subtasks for a safe approach to completing totally endoscopic tragal cartilage tympanoplasty. A risk score for each subtask was calculated to produce a systematic human error reduction and prediction approach and to highlight potential errors. CONCLUSION This hierarchical task analysis allowed for quick reference to a correct method of endoscopic tympanoplasty. The systematic human error reduction and prediction approach was employed to reduce the risks associated with undergoing endoscopic tympanoplasty, to improve patient safety.

Jeon H, Song IS, Park JG, Lee H, Han E, Park S, Lee Y, Song CM, Hur W, Lee IG, Choi J. Protective effects of esomeprazole against cisplatin-induced ototoxicity: an in vitro and in vivo study. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2023; 260:106573. [PMID: 37210931 DOI: 10.1016/j.aquatox.2023.106573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 05/06/2023] [Accepted: 05/11/2023] [Indexed: 05/23/2023]
Abstract
In this study, we aimed to identify novel compounds that could afford protection against cisplatin-induced ototoxicity by employing both cell- and zebrafish (Danio rerio)-based screening platforms. We screened 923 US Food and Drug Administration-approved drugs to identify potential compounds exhibiting protective effects against cisplatin-induced ototoxicity in HEI-OC1 cells (auditory hair cell line). The screening strategy identified esomeprazole and dexlansoprazole as the primary hit compounds. Subsequently, we examined the effects of these compounds on cell viability and apoptosis. Our results revealed that esomeprazole and dexlansoprazole inhibited organic cation transporter 2 (OCT2), thus providing in vitro evidence that these compounds could ameliorate cisplatin-induced ototoxicity by directly inhibiting OCT2-mediated cisplatin transport. In vivo, the protective effects were validated using zebrafish; esomeprazole was found to decrease cisplatin-induced hair cell damage in neuromasts. Furthermore, the esomeprazole-treated group showed a significantly lower number of TUNEL-positive cells than the cisplatin-treated group. Collectively, our findings revealed that esomeprazole exerts a protective effect against cisplatin-induced hair cell damage in both HEI-OC1 cells and a zebrafish model.
