The utility of a machine learning model in identifying people at high risk of type 2 diabetes mellitus.

Background: According to previous reports, very high percentages of individuals in Saudi Arabia are undiagnosed for type 2 diabetes mellitus (T2DM). Despite conducting several screening and awareness campaigns, these efforts lacked full accessibility and consumed extensive human and material resources. Thus, developing machine learning (ML) models could enhance the population-based screening process.

Post-COVID-19 syndrome: nature of symptoms and associated factors.

Aim: Post-COVID-19 syndrome is defined as continuous symptoms related to SARS-CoV-2 infection, which can persist for several weeks or months. Previous studies identified risk factors associated with post-COVID-19 syndrome, including female sex, hypertension, and allergic respiratory diseases. This study aims to investigate the frequency of this syndrome among Arabic patients.

COVID-19 vaccine acceptance: knowledge and beliefs.

Backgrounds: Vaccine acceptance varies across countries, generations, and the perceived personality of individuals. Investigating the knowledge, beliefs, and acceptability of COVID-19 vaccines among individuals is vital to ensuring adequate health system capacity and procedures and promoting the uptake of the vaccines.

Results: A cross-sectional study was conducted from August 2021 to January 2022 in Saudi Arabia.

Protective Duration of ChAdOx1 and BNT162b2 Vaccines Against SARS-CoV-2 Infection.

Background And Objective: A limited number of studies have addressed the protective duration of coronavirus disease 2019 (COVID-19) vaccines following primary and booster doses in Saudi Arabia. Therefore, this study aimed to evaluate the protective duration of primary and booster doses of BNT162b2 and ChAdOx1 COVID-19 vaccine batches in Saudi Arabia.

Methods: A cross-sectional study was conducted from 1 January to 31 December, 2021.

Adverse drug reactions from two COVID-19 vaccines reported in Saudi Arabia.

Background: Several reports have been published about the impact of coronavirus disease 2019 (COVID-19) vaccines on human health, and each vaccine has a different safety and efficacy profile. The aim of this study was to reveal the nature and classification of reported adverse drug reactions (ADRs) of the two COVID-19 vaccines (tozinameran and ChAdOx1) among citizens and residents living in Saudi Arabia, and show possible differences between the two vaccines and the differences between each batch on the health of populations.

Methods: A cross-sectional study was conducted in Saudi Arabia between December 2020 and March 2021.

Knowledge, beliefs, and acceptability of people toward new COVID-19 vaccines: a pilot study.

A cross-section pilot study was done to determine the knowledge and belief toward new COVID-19 vaccines among a small sample size group of people. A new Vaccine Acceptability Questionnaire (VAQ) consists of 31 questions that were concerned about three elements: underlying factors, knowledge, and beliefs. The study included 96 people from the different regions of Saudi Arabia who had accepted to participate in this pilot study.

A comparative study of online learning in response to the coronavirus disease 2019 pandemic versus conventional learning.

Objectives: To explore the attitude and perception of undergraduate medical students and their staff towards the educational methods (conventional versus online) and to assess their performance accordingly.

Methods: It was a comparative cross sectional study, conducted at the Faculty of Medicine, Al- Imam University, Riyadh, Saudi Arabia on May 30, 2020. A structured questionnaire was designed to collect the data from students and staff about conventional teaching, online teaching, conventional examination and online examination.

Ultra Wideband Indoor Positioning Technologies: Analysis and Recent Advances.

In recent years, indoor positioning has emerged as a critical function in many end-user applications; including military, civilian, disaster relief and peacekeeping missions. In comparison with outdoor environments, sensing location information in indoor environments requires a higher precision and is a more challenging task in part because various objects reflect and disperse signals. Ultra WideBand (UWB) is an emerging technology in the field of indoor positioning that has shown better performance compared to others.

The thermoluminescence glow curve and the deconvoluted glow peak characteristics of erbium doped silica fiber exposed to 70-130 kVp x-rays.

In regard to thermoluminescence (TL) applied to dosimetry, in recent times a number of researchers have explored the role of optical fibers for radiation detection and measurement. Many of the studies have focused on the specific dopant concentration, the type of dopant and the fiber core diameter, all key dependencies in producing significant increase in the sensitivity of such fibers. At doses of less than 1 Gy none of these investigations have addressed the relationship between dose response and TL glow peak behavior of erbium (Er)-doped silica cylindrical fibers (CF).

Structural, spectral, thermal and biological studies on (Z)-N-benzoyl-N'-(2-oxo-2-(phenylamino)acetyl)carbamohydrazonothioic acid (H₂PABT) and its Cd(II), Hg(II), Zn(II) and U(VI)O₂²⁺ complexes.

A new metal complexes formed by the reaction of (Z)-N-benzoyl-N'-(2-oxo-2-(phenylamino)acetyl)carbamohydrazonothioic acid (H2PABT) and Cd(II), Hg(II), Zn(II) and U(VI)O2(2+) ions. The isolated complexes were prepared and characterized by conventional techniques. The IR data revealed that the ligand behaves as mononegative tridentate in Zn(II) and U(VI)O2(2+) complexes also, binegative tetradentate on Cd(II) and Hg(II) complexes.

The thermoluminescence characteristics and the glow curves of Thulium doped silica fiber exposed to 10MV photon and 21MeV electron radiation.

The thermoluminescence (TL) glow curves and kinetics parameters of Thulium (Tm) doped silica cylindrical fibers (CF) are presented. A linear accelerator (LINAC) was used to deliver high-energy radiation of 21MeV electrons and 10MV photons. The CFs were irradiated in the dose range of 0.

Faculty development program: a guide for medical schools in Arabian Gulf (GCC) countries.

The effective faculty development (FD) program is the most essential component for creating successful educational innovation. The purpose of having any FD program is to enable faculty to accomplish their goals, and through accomplishing these goals, the missions of their departments, colleges, and universities would be accomplished. FD programs will need to provide an extensive set of developmental-educational skills and strategies in order to serve faculty members who come from various disciplines and at different stages of their careers, have different faculty responsibilities, backgrounds, appointments, and bring unique personal circumstances to their work.
