Article Abstract
Quantitative ultrasound (QUS) imaging is a safe, reliable, inexpensive, and real-time technique to extract physically descriptive parameters for assessing pathologies. Compared with other major imaging modalities such as computed tomography and magnetic resonance imaging, QUS suffers from several major drawbacks: poor image quality and inter- and intra-observer variability. Therefore, there is a great need to develop automated methods to improve the image quality of QUS. In recent years, there has been increasing interest in artificial intelligence (AI) applications in medical imaging, and a large number of research studies in AI in QUS have been conducted. The purpose of this review is to describe and categorize recent research into AI applications in QUS. We first introduce the AI workflow and then discuss the various AI applications in QUS. Finally, challenges and future potential AI applications in QUS are discussed.

Association of heel bone mineral density with incident dementia among ageing adults: a population-based study from the UK Biobank.
Aging Clin Exp Res

Perron Institute for Neurological and Translational Science, University of Western Australia, 8 Verdun St, Nedlands, WA, 6009, Australia.
Background: Osteoporosis and dementia are two common disorders mainly affecting ageing population, and heel estimated bone mineral density (eBMD) measured by quantitative ultrasound (QUS) has been demonstrated to be a reliable and non-invasive method for assessing skeletal health. The aim of this study is to determine the association between eBMD and incident dementia in older adults.
Methods: This retrospective cohort study employs UK Biobank data of 131,030 adults aged ≥ 60 years without dementia at baseline.

Quercetin (Qu), a naturally occurring flavonoid with potent antioxidant, anti-inflammatory, and anticancer properties, faces clinical limitations due to poor solubility, low stability, and suboptimal bioavailability. This review comprehensively explores nano-quercetin (nano-Qu) formulations as a transformative solution, focusing on material design, synthesis strategies, and biomedical applications. A comprehensive review of diverse nanocarriers, including lipid-based, inorganic, polymeric, and composite nanoparticles, is presented to systematically evaluate their potential in improving solubility, stability, and targeted drug delivery of Qu.

Objective: Bone densitometry and fracture risk algorithms have proved scarce reliability for fractures risk estimation in patients with diabetic osteopathy. Calcaneal quantitative ultrasound (QUS) is a noninvasive, low-cost technique already acknowledged for fracture risk assessment in patients with primary osteoporosis. Nevertheless, there is limited evidence on the role of QUS in patients with diabetes mellitus (DM).

Objective: The evaluation of bone health during the growth stage is extremely important, as it is a key factor to prevent bone diseases in adulthood. The objectives of the study were: a) to verify if there are differences in bone health with other geographic regions, b) to develop bone health curves using quantitative ultrasonography (QUS) through the Broadband Ultrasonic Attenuation (BUA) parameter in children and adolescents residing in a high altitude region of Peru and c) to determine specific cut-off points for bone health assessment in this particular population.
Methods: A cross-sectional study was carried out in schoolchildren in a high altitude region of Peru.

Background/aim: Osteoporosis is a global health concern causing severe fractures, and timely diagnosis with thorough bone assessment is crucial for effective management. Diagnostic tools such as Bindex (a novel ultrasound-based diagnostic technology) and DXA (X-ray-based) play a key role in identifying and assessing bone conditions. This study aimed to evaluate and compare these two approaches' overall acceptability, comfort, and preference.
