Synthesis, characterization, molecular modeling studies, and biological evaluation of metal piroxicam complexes (M = Ni(II), Pt(IV), Pd(II), Ag(I)) as antibacterial and anticancer agents.

Four piroxicam metal complexes; NiL , PtL , PdL , and AgL were synthesized and characterized by different techniques with enhanced antibacterial and anticancer activity. Regarding in vitro antimicrobial activity, complex NiL displayed potent antibacterial effect against Escherichia coli and Pseudomonas aeruginosa that was 1.9-folds higher than piroxicam (minimum inhibitory concentration [MIC] = 31.

Longevity of Immunoglobulin-G Antibody Response Against Nucleocapsid Protein Against SARS-CoV-2 Among Healthcare Workers.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused the latest pandemic and the most significant challenge in public health worldwide. Studying the longevity of naturally developed antibodies is highly important clinically and epidemiologically. This paper assesses the longevity of antibodies developed against nucleocapsid protein amongst our health-care workers.

Assessment of binding interaction to salmon sperm DNA of two antiviral agents and ecofriendly nanoparticles: comprehensive spectroscopic study.

The direct binding of antiviral agents; Daclatasvir and valacyclovir and green synthesized nanoparticles to salmon sperm DNA have been assessed in a comparative study. The nanoparticles were synthesized by the hydrothermal autoclave method and have been fully characterized. The interactive behavior and competitive binding of the analytes to DNA in addition to the thermodynamic properties were deeply investigated by the UV-visible spectroscopy.

A Cohort Study of Seroprevalence of Antibodies Against SARS-CoV-2 Infection Among Healthcare Workers at a Tertiary Hospital in Saudi Arabia.

Background: The nature of the healthcare workers' jobs standing at the frontline against the coronavirus disease 2019 (COVID-19) puts them at a higher risk of unknowingly contracting the disease and potentially contributing to the spread. This study aims to assess the overall positive seroconversion prevalence of SARS-CoV-2.

Methods: This is a longitudinal cohort study of healthcare workers at Johns Hopkins Aramco Healthcare (JHAH).

Comparing the use of Arabic decision aid to usual care. A multicenter randomized controlled trial for Arabic speaking metastatic colorectal cancer patients in Saudi Arabia.

Objectives: To evaluate the effect of decision aids (DAs) for metastatic colorectal cancer (mCRC) patients in the Arabic language.

Methods: A multi-centered randomized control trial was used to evaluate the effect of Arabic DA use with usual care for mCRC patients compared to usual care alone. Patients were recruited from 4 main oncology centers in Saudi Arabia: King Fahad Medical City, Riyadh; King Khalid University Hospital, Riyadh; King Saud Medical City, Riyadh; and King Fahd Specialist Hospital, Dammam, Saudi Arabia, between March 2016 and  October 2018.

Awareness, understanding, attitude and barriers toward prescribing modern cancer immunotherapies in the Arabian Gulf countries.

Introduction: The use of modern immunotherapy has been evolving over the past few years, and various new agents have been developed for new indications at multiple primary sites in oncology. It is important for physicians who are involved in cancer care to be aware and updated about new therapeutic agents and their indications, potential benefits, and side effects.

Patients And Methods: From October to November 2017, we conducted a survey on the awareness, understanding, attitude, and barriers associated with prescribing modern cancer immunotherapies among physicians in the Arabian Gulf countries.

Detailed disclosure to Saudi Arabian patients on risks related to an invasive procedure.

Objective: To measure the effect of providing a detailed description of coronary angiography risks on obtaining informed consent from Saudi Arabian patients.

Methods: This randomized controlled trial was conducted at King Khalid University Hospital, Riyadh, Saudi Arabia from August 2006 to June 2007. Patients were randomized to either an information sheet containing brief information on procedure-related risks (brief sheet), or full disclosure of risks (detailed sheet).
