Exploring anesthesiology nurse' presenteeism in China: cross-sectional study.

BACKGROUND: The department of anesthesiology is the main battlefield for the treatment of acute and critical patients, with high work risk and high work pressure. Due to the particularity of the working environment and nature of work, medical staff have become a group with a high incidence of occupational exhaustion and presenteeism. OBJECTIVE: To investigate the current status of presenteeism among anesthesiology nurses in China and to analyze the related influencing factors. METHODS: Three hundred twelve anesthesiology nurses in Sichuan Province were surveyed by means of general data questionnaire, presenteeism scale, work-family conflict scale, perceived social support scale, occupational commitment scale and stress resistance scale from September to November 2023 by convenience sampling method. RESULTS: The total score of presenteeism was (14.67 ± 3.92), the score of work-family conflict was (45.44 ± 15.90), the score of professional commitment was (87.28 ± 14.30), and the score of perceived social support was (66.04 ± 12.78). The evaluation score of stress resistance was (73.35 ± 11.54). The results of multivariate analysis showed that age, education, mode of employment, position, overtime hours per week, work-family conflict, perceived social support and stress resistance were the factors that affected the presenteeism of anesthesiology nurses, which could explain 44.1% of the total variation. The position ( ß = 0.296, P < 0.001), overtime hours per week (h) ( ß = 0.271, P < 0.001), perceived social support ( ß = -0.279, P < 0.001) turned out as the stronger predictors of presenteeism. CONCLUSION: The presenteeism of anesthesiology nurses is at a high level and needs to be further improved. Clinical nursing managers should pay attention to the physical and mental health and special needs of anesthesiology nurses. Interventions are made according to the main influencing factors, so as to reduce the incidence of presenteeism and improve the quality and safety of surgery.

Interactive mode of biochar-based silicon and iron nanoparticles mitigated Cd-toxicity in maize.

Cadmium contamination poses severe environmental and health threats, necessitating effective mitigation strategies. Rice husk biochar (BC) and nanoparticle (NP) treatments are emerging strategies with limited research on their synergistic benefits. This study assesses BC, silicon NPs (nSi), and iron NPs (nFe) modifications (B-nSi, B-nFe, and B-nSi-nFe) to reduce Cd-bioavailability in soil and its toxicity in maize, not reported before. Characterization of amendments validated, nSi and nFe attachment to BC, forming new mineral crystals to adsorb Cd. We found that B-nSi-nFe induced Cd-immobilization in soil by the formation of Cd-ligand complexes with the effective retention of NPs within microporous structure of BC. B-nSi-nFe increased soil pH by 0.76 units while reducing bioavailable Cd by 49 %, than Ck-Cd. Resultantly, B-nSi-nFe reduced Cd concentrations in roots and shoots by 51 % and 75 %, respectively. Moreover, the application of B-nSi-nFe significantly enhanced plant biomass, antioxidant activities, and upregulated the expression of antioxidant genes [ZmAPX (3.28 FC), ZmCAT (3.20 FC), ZmPOD (2.58 FC), ZmSOD (3.08 FC), ZmGSH (3.17 FC), and ZmMDHAR (3.80 FC)] while downregulating Cd transporter genes [ZmNramp5 (3.65 FC), ZmHMA2 (2.92 FC), and ZmHMA3 (3.40 FC)] compared to Ck-Cd. Additionally, confocal microscopy confirmed the efficacy of B-nSi-nFe in maintaining cell integrity due to reduced oxidative stress. SEM and TEM observations revealed alleviation of Cd toxicity to stomata, guard cells, and ultracellular structures with B-nSi-nFe treatment. Overall, this study demonstrated the potential of B-nSi-nFe for reducing Cd mobility in soil-plant system, mitigating Cd-toxicity in plants and improving enzymatic activities in soil.
