Abstract Objectives To investigate healthcare professionals’ knowledge, attitudes, and practices (KAPs) of the environmental impact and sustainability of iodinated contrast media (ICM). Materials and methods A cross-sectional web-based survey was distributed to members of profess...

Perceptions and intended use of the Hall Technique among dentists in Saudi Arabia: an exploratory cross-sectional survey

The Hall Technique (HT) is a minimally invasive approach for managing carious primary molars without local anesthesia, caries removal, or tooth preparation. Evidence on dentists’ perceptions and intended use of HT in Saudi Arabia remains limited. This exploratory study described...

Perceptions of micro-learning modules on knowledge retention and clinical decision-making among physiotherapists: a cross-sectional study

Micro-learning has emerged as an innovative strategy for professional development in healthcare. Although its effectiveness has been demonstrated in various health professions, physiotherapists’ perceptions of its impact on knowledge retention and clinical decision-making remain...

Association Between Cigarette Smoking and Carotid Plaque Stiffness Assessed Using Ultrasound Shear-Wave Elastography

Background: Cigarette smoking alters carotid plaque composition. Two-dimensional ultrasound shear-wave elastography (2D-SWE) is a promising non-invasive imaging technique for quantifying plaque stiffness. This prospective study aimed to determine whether carotid plaque stiffness...

Comparison of joint mobilization vs. strengthening exercises for improving cervical proprioception in individuals with nonspecific neck pain: a randomized clinical trial

Patients with neck pain often experience proprioceptive dysfunction and other impairments. Although strengthening exercises and cervical joint mobilization effectively improve proprioception, their comparative effects remain unclear. This study compared cervical joint mobilizatio...

Gas-driven needle-free dental injection enables tunable and predictable soft-tissue penetration: high-speed kinematic and micro-computed tomography validation

Needle-free jet injectors are a promising alternative to conventional dental needles, particularly for patients with injection-related fear. However, the actuation mechanism can substantially affect jet formation, delivery consistency, and tissue penetration. This study compared...

Beclin-1 and HIF-1α immunohistochemical expression in breast carcinoma: insights into tumor biology

Breast carcinoma is a biologically heterogeneous disease in which tumor behavior and clinical outcome are influenced by multiple cellular pathways, including autophagy and hypoxia. Beclin-1, a key autophagy-related protein, and hypoxia-inducible factor-1α (HIF-1α), a central regu...
