Quality and safety issue: language barriers in healthcare, a qualitative study of non-Arab healthcare practitioners caring for Arabic patients in the UAE.

OBJECTIVES: To identify language-related communication barriers that expatriate (non-Arabic) healthcare practitioners in the UAE encounter in their daily practice. DESIGN: Qualitative study utilising semi-structured in-depth interviews. The interviews were conducted in English language. SETTING: Different healthcare facilities across the UAE. These facilities were accessed for data collection over a period of 3 months from January 2023 to March 2023. PARTICIPANTS: 14 purposively selected healthcare practitioners. INTERVENTION: No specific intervention was implemented; this study primarily aimed at gaining insights through interviews. PRIMARY AND SECONDARY OUTCOMES: To understand the implications of language barriers on service quality, patient safety, and healthcare providers' well-being. RESULTS: Three main themes emerged from our analysis of participants' narratives: Feeling left alone, Trying to come closer to their patients and Feeling guilty, scared and dissatisfied. CONCLUSIONS: Based on the perspectives and experiences of participating healthcare professionals, language barriers have notably influenced the delivery of healthcare services, patient safety and the well-being of both patients and practitioners in the UAE. There is a pressing need, as highlighted by these professionals, for the inclusion of professional interpreters and the provision of training to healthcare providers to enhance effective collaboration with these interpreters.

In vitro assessment of the antimicrobial efficacy of chitosan nanoparticles against major fish pathogens and their cytotoxicity to fish cell lines.

Nanotechnology is an emerging avenue employed in disease prevention and treatment. This study evaluated the antimicrobial efficacy of chitosan nanoparticles (CSNPs) against major bacterial and oomycete fish pathogens in comparison with chitosan suspension. Initially, the minimum inhibitory concentrations (MIC, MIC90 ) were determined and the per cent inhibition of bacterial growth was calculated. Subsequently, the minimum bactericidal concentrations (MBCs) were determined. The time-dependent disruptions of CSNP-treated pathogens were observed via transmission electron microscopy (TEM), and the effect of CSNPs on the viability of two fish cell lines was assessed. No antimicrobial effect was observed with chitosan, while CSNPs (105 nm) exhibited a dose-dependent and species-specific antimicrobial properties. They were bactericidal against seven bacterial isolates recording MBC values from 1 to 7 mg/ml, bacteriostatic against four further isolates recording MIC values from 0.125 to 5 mg/ml and fungistatic against oomycetes recording MIC90 values of 3 and 4 mg/ml. TEM micrographs showed the attachment of CSNPs to the pathogenic cell membranes disrupting their integrity. No significant cytotoxicity was observed using 1 mg/ml CSNPs, while low dose-dependent cytotoxicity was elicited by the higher doses. Therefore, it is anticipated that CSNPs are able to compete and reduce using antibiotics in aquaculture.
