Occupational Exposure to Sharp Object Injuries Among Healthcare Workers in Dammam and Jeddah Hospitals, Saudi Arabia‏.

Objective: This study identify the prevalence of sharp object injuries (SOIs) among healthcare workers (HCWs) in Dammam and Jeddah, Saudi Arabia.

Methods: Quantitative methodology using a cross-sectional design was applied. Chi-square testing was employed for comparative analyses, and logistic regression encompassing univariate and multivariate models was implemented to ascertain the predictors of SOIs.

Public Anxiety, Attitudes, and Practices towards COVID-19 Infection in the Eastern Province of Saudi Arabia: A Cross-Sectional Study.

Coronavirus disease 2019, or COVID-19, still has a terrifying potential due to its continuous genetic variation. Although vaccines have been created, adherence to preventive measures remains a privileged choice to tackle the pandemic. This study aims to investigate the anxiety, attitudes, and practices (KAPs) towards COVID-19 infection in the Eastern Province of Saudi Arabia.

Synthesis of M-AgPO, (M = Se, Ag, Ta) Nanoparticles and Their Antibacterial and Cytotoxicity Study.

Silver Phosphate, Ag3PO4, being a highly capable clinical molecule, an ultrasonic method was employed to synthesize the M-Ag3PO4, (M = Se, Ag, Ta) nanoparticles which were evaluated for antibacterial and cytotoxicity activities post-characterization. Escherichia coli and Staphylococcus aureus were used for antibacterial testing and the effects of sonication on bacterial growth with sub-MIC values of M-Ag3PO4 nanoparticles were examined. The effect of M-Ag3PO4 nanoparticles on human colorectal carcinoma cells (HCT-116) and human cervical carcinoma cells (HeLa cells) was examined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) assay and DAPI (4′,6-diamidino-2-phenylindole) staining.

Impact of Nanolayered Material and Nanohybrid Modifications on Their Potential Antibacterial Activity.

Due to an escalating increase in multiple antibiotic resistance among bacteria, novel nanomaterials with antimicrobial properties are being developed to prevent infectious diseases caused by bacteria that are common in wastewater and the environment. A series of nanolayered structures and nanohybrids were prepared and modified by several methods including an ultrasonic technique, intercalation reactions of fatty acids, and carbon nanotubes, in addition to creating new phases based on zinc and aluminum. The nanomaterials prepared were used against a group of microorganisms, including , , and .

Potential impact of great lockdown on students' knowledge, attitude and practices towards the COVID-19 outbreak.

 Despite variation in the types of COVID-19 vaccines and genetic variation in the SARS-CoV-2 genome, using preventive measures remains the first choice to reduce risks associated with COVID-19 infection.  This cross-sectional study highlights students' knowledge, attitudes, and practices toward SARS-CoV-2 infection during lockdown. The study was conducted at the Imam Abdulrahman Bin Faisal University (IAU), Eastern Province, Saudi Arabia.
