Introduction: Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental condition in children in Saudi Arabia. ADHD significantly impacts children and their families, particularly by increasing parental stress and diminishing quality of life. In Saudi Arabia, there is a research gap regarding the quality of life and coping mechanisms of parents managing children with ADHD.

Improvements in bone density/erosion and turnover may not go hand in hand with a positive clinical response to biological anti-inflammatory drugs assesed by disease activity score 28 (DAS28) in RA patients. This study aimed to understand how biologic anti-inflammatory drugs affect bone density, erosion, and turnover in RA patients.

This study examined physicians' vaccination knowledge, vaccine-related discussions with VHPs, beliefs about and responses to vaccine hesitancy, and challenges faced while discussing immunization with VHPs.
Methods: This cross-sectional, descriptive study was performed at King Saud University Medical City (KSUMC), Riyadh, Saudi Arabia, in September 2020.
Article Synopsis
- A new radioluminescence-based survey meter has been developed to detect naturally occurring radioactive materials (NORM) and other weak radiation emitters, addressing limitations of existing handheld meters.
- The device utilizes a LYSO:Ce scintillator and a photodetector connected through a polymer optical fiber, making it safe for inspecting hard-to-reach industrial components like pipework and valves.
- Initial tests show the system has good sensitivity across a dose-rate range of 0.10 to 80 µSv/h, proving effective for detecting low-level radioactivity in challenging environments.
