ABSTRACT

BACKGROUND: Artificial intelligence is rapidly advancing and being integrated into healthcare, potentially revolutionizing patient care and improving outcomes by leveraging large datasets and complex algorithms. AIM: Investigate the moderating role of ethical awareness between nurses' artificial intelligence perceptions, attitudes, and innovative work behaviors. DESIGN AND METHODS: A cross-sectional descriptive correlational design adhering to STROBE guidelines. A non-probability convenience sample of 415 Alexandria Main University Hospital nurses was analyzed. Statistical methods included one-way ANOVA, the student t-test, and the Pearson coefficient, with results evaluated for significance at the 5% level and internal consistency assessed via Cronbach's α. Linear regression assessed the predicting and moderating effect between ethical awareness, nurses' artificial intelligence perceptions, attitudes, and innovative work behavior. The perceptions of using the Artificial Intelligence Scale, general attitudes towards the Artificial Intelligence Scale, ethical awareness of Using Artificial Intelligence, and the Employee Innovative Behavior Scale were used to respond to the research aim. RESULTS: The study revealed that perception of AI use among nurses has a mean score of 50.25 (SD = 3.49), attitudes towards AI have a mean score of 71.40 (SD = 4.98), ethical awareness regarding AI use shows a mean score of 43.85 (SD = 3.39), and nurses innovative behavior exhibits a mean score of 83.63 (SD = 5.22). Attitude and ethical awareness were statistically significant predictors of innovation. Specifically, for every one-unit increase in attitude, innovative work behaviors increase by 1.796 units (p = 0.001), and for every one-unit increase in ethical awareness, innovative work behaviors increase by 2.567 units (p = 0.013). The interaction effects between perception, ethical awareness, attitude, and ethical awareness were also examined. Only the interaction between attitude and ethical awareness was found to be significant (p = 0.002), suggesting that the effect of attitude on innovative work behaviors depends on the level of ethical awareness. In other words, ethical awareness moderates the relationship between attitudes and innovative work behaviors rather than perception and innovation. CONCLUSION: There is a statistically significant correlation between attitude, ethical awareness, and creativity, highlighting that ethical awareness moderates the relationship between attitudes and innovative work behaviors. These findings emphasize the importance of ethical awareness in fostering positive attitudes towards AI and enhancing innovative practices in nursing, ultimately contributing to nurses' well-being.

ABSTRACT

AIM: Investigate the influence of organizational intelligence on the development of soft skills and the overall thriving of nurses at Alexandria Main University Hospital in Egypt. DESIGN: A cross-sectional descriptive design following STROBE guidelines examined the relationship between organizational intelligence, soft skills, and nurses' thriving. METHODS AND TOOLS: Data were collected from 740 nurses working across critical care units using structured questionnaires. The questionnaires assessed organizational intelligence, soft skills, and thriving at work. Sociodemographic characteristics, including age, gender, education, and nursing experience, were also collected. Statistical analyses were used to analyze the data, including ANOVA, t-tests, Pearson correlation, and stepwise regression. RESULTS: The findings revealed nurses' positive perceptions of organizational culture and documentation skills. However, areas such as measures and rewards and staff relations and communication indicated opportunities for improvement. Nurses reported high vitality levels but needed more learning opportunities at work. Significant correlations were found between demographic variables, organizational intelligence, soft skills, and thriving. Organizational intelligence demonstrated a robust positive relationship with both soft skills and thriving. Age, gender, education, and experience significantly influenced nurses' soft skills and thriving. CONCLUSION: The study highlights the importance of organizational intelligence in enhancing nurses' professional capabilities and well-being. Addressing demographic factors and fostering a supportive work environment is crucial for optimizing nursing practice and organizational effectiveness. NURSING IMPLICATIONS: Insights from this study can inform targeted interventions and policy decisions to enhance nursing practice, organizational development, and healthcare outcomes in Egypt. Fostering organizational intelligence and soft skills among nurses can improve patient care, increase job satisfaction, and overall organizational success.

ABSTRACT

Aim: This study was designed to synthesize a novel series of terpyridines with potential antibacterial properties, targeting multidrug resistance. Materials & methods: Terpyridines (4a-h and 6a-c) were synthesized via a one-pot multicomponent reaction using 2,6-diacetylpyridines, benzaldehyde derivatives and malononitrile or ethyl 2-cyanoacetate. The reactions, conducted under grinding conditions with glacial acetic acid, produced high-yield compounds, confirmed by spectroscopic data. Results: The synthesized terpyridines exhibited potent antibacterial activity. Notably, compounds 4d and 4h demonstrated significant inhibition zones against Staphylococcus aureus and Bacillus subtilis, outperforming ciprofloxacin. Conclusion: Molecular docking studies highlighted compounds 4d, 4h and 6c as having strong binding affinity to DNA gyrase B, correlating with their robust antibacterial activity, suggesting their potential as effective agents against multidrug-resistant bacterial strains.

ABSTRACT

BACKGROUND: The prevalence of long diffuse coronary artery disease (CAD) is increasing nowadays due to increase prevalence of multiple risk factors and population ageing. We aimed in our study to show the differences clinically or angiographically (guided by IVUS) between the use of single long stent versus overlapping stents in very long coronary lesions (≥40 mm) in patients presented with chronic coronary syndromes. METHODS: 550 patients presenting with chronic coronary syndromes were included: 320 treated with a single long stent (≥40 mm) and 230 patients with two or more overlapping stents. Angiographic follow-up (guided by IVUS) 6 months after PCI was performed only in 50 patients. We assessed the procedural characteristics and the occurrence of major adverse cardiovascular events (MACE) after a median follow-up of 24 months. RESULTS: Total stent length was 56.16 ± 14.85 mm and mean diameter was 3.05 ± 0.36 mm. At the end of follow-up, MACE rate in the single long stent group was 4.1% vs. 7.8% in the overlapping stents group, with higher incidence in overlapping stents group but non-statistically significant (p value = 0.059). PCI using overlapping stents consumed more contrast volume (248 ± 85.36 vs 164.5 ± 70.43 ml, p < 0.001), and higher fluoroscopy time (23.65 ± 9.19 vs 19.72 ± 9.19 min, p < 0.001). Regarding IVUS subgroup follow-up, there was no significant difference between both groups regarding in-stent restenosis and MACE. CONCLUSIONS: We can conclude that long or overlapping stents are both acceptable therapeutic choices for patients with long CAD. There was no difference between both strategies regarding angiographic follow-up guided by IVUS after 6 months.

ABSTRACT

Globally, hepatocellular carcinoma (HCC) is the fourth most common cause of death from cancer. The prevalence of this pathology, which has been on the rise in the last 30 years, has been predicted to continue increasing. HCC is the most common cause of cancer-related morbidity and mortality in Egypt and is also the most common cancer in males. Chronic liver diseases, including chronic hepatitis C, which is a primary health concern in Egypt, are considered major risk factors for HCC. However, HCC surveillance is recommended for patients with chronic hepatitis B virus (HBV) and liver cirrhosis; those above 40 with HBV but without cirrhosis; individuals with hepatitis D co-infection or a family history of HCC; and Nonalcoholic fatty liver disease (NAFLD) patients exhibiting significant fibrosis or cirrhosis. Several international guidelines aid physicians in the management of HCC. However, the availability and cost of diagnostic modalities and treatment options vary from one country to another. Therefore, the current guidelines aim to standardize the management of HCC in Egypt. The recommendations presented in this report represent the current management strategy at HCC treatment centers in Egypt. Recommendations were developed by an expert panel consisting of hepatologists, oncologists, gastroenterologists, surgeons, pathologists, and radiologists working under the umbrella of the Egyptian Society of Liver Cancer. The recommendations, which are based on the currently available local diagnostic aids and treatments in the country, include recommendations for future prospects.

ABSTRACT

Zinc sulfide (ZnS) nanoparticles were fabricated using the chemical precipitation method. The X-ray diffraction (XRD), Raman spectroscopy, and scanning electron microscopy (SEM) techniques were used to investigate the structural parameters of the formed ZnS. The hexagonal crystal structure of the Zn and ZnS phases was formed. The average crystallite size of the ZnS phase is 10.3 nm, which is much smaller than that of the Zn phase (54.5 nm). Several frequencies and phonon modes were detected in the Raman scattering spectrum belonging to the ZnS nanoparticles. The synthesized ZnS nanoparticles were used as catalysts to eliminate the Congo red (CR) dye, with different concentrations, from synthetic wastewater. The impact of the CR dye concentration and shaking period on the adsorption of CR was thoroughly investigated, and various adsorption kinetic models were tested. After 3 h of shaking, the adsorption efficiency reached 26.01% for 40 mg/L CR dye and 27.84% for 20 mg/L CR dye. The adsorption capacities of the CR dye in the presence of ZnS are 16% and 9% for 40 and 20 mg/L, respectively. Based on the correlation factor, the intraparticle diffusion kinetic model was considered the best of the tested models.

ABSTRACT

In the present study, a novel series of 2-(2-(3-aryl-5-substituted-1,3,4-thiadiazol-2(3H)-ylidene)hydrazinyl)-4,4-diphenyl-1H-imidazol-5(4H)-one derivatives were designed and prepared via the reaction of the most versatile, hitherto unreported 2-(5-oxo-4,4-diphenyl-4,5-dihydro-1H-imidazol-2-yl)-N-phenylhydrazinecarbothioamide with the appropriate hydrazonoyl halides. In addition, some thiazole derivatives were prepared. The structures of the newly synthesized compounds were established based on spectroscopic evidences and their alternative syntheses. Some of the newly synthesized compounds have been evaluated for their anticancer activity against a liver carcinoma cell line HEPG2-1. Moreover, their structure-activity relationship (SAR) was explored for further development in this area. The results indicated that many of the tested compounds showed moderate to high anticancer activity with respective to doxorubicin as a reference drug. Consequently, the new synthesized series of thiadiazole-imidazole derivatives are considered as powerful anticancer agents.
