SPECIFIC SITES OF BONE EXPANSION DEPEND ON THE LEVEL OF VOLLEYBALL PRACTICE IN PREPUBESCENT BOYS

Biology of Sport, 2013
The purpose of this study was to investigate the effect of 18 months of high and low levels of volleyball practice on bone acquisition. 130 prepubescent boys (mean age 11.4 ± 0.7) were divided into a high-level training group (HLG), low-level training ...

The contemporary management of prostate cancer

CA: A Cancer Journal for Clinicians, Volume 75, Issue 6, Page 552-586, November/December 2025.
Abstract Prostate cancer is the most common cancer in two thirds of the world, with an expected doubling in both incidence and mortality in the next two decades. No strong environmental associations exist for the development of prostate cancer; therefore, lifestyle measures are unlikely to mitigate this increasing burden.

Artificial intelligence in the diagnosis of gastro‐entero‐pancreatic neuroendocrine neoplasms: Potential benefits and current limitations

Journal of Neuroendocrinology, Volume 37, Issue 11, November 2025.
Gastro‐entero‐pancreatic neuroendocrine neoplasms (GEP‐NENs) exhibit substantial clinical heterogeneity and necessitate a multidisciplinary, personalized approach. Artificial intelligence (AI), through advanced imaging analysis and predictive modeling, offers new opportunities to support diagnosis and guide management.

Triple‐energy photon‐counting x‐ray imaging for bone‐strontium estimation: A simulation study

Medical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Strontium quantification in bone is clinically relevant but typically requires specialized stand‐alone systems. Photon‐counting detectors offer energy‐resolved imaging that may enable low‐dose estimation of both strontium concentration and bone mineral density in a single acquisition.

ODIASP: An Open‐Source Software for Automated SMI Determination—Application to an Inpatient Population

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 4, August 2025.
ABSTRACT Background The diagnosis of malnutrition has evolved with the GLIM recommendations, which advocate for integrating phenotypic criteria, including muscle mass measurement. The GLIM framework specifically suggests using skeletal muscle index (SMI) assessed via CT scan at the third lumbar level (L3) as a first‐line approach.

Reference Data and Predictors of HR‐pQCT‐Derived Muscle Density and Its Prediction of Physical Performance

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 4, August 2025.
ABSTRACT Background There is increasing awareness of a role for muscle composition in sarcopenia and cachexia. Computed tomography (CT)–based measures of muscle density (MusD) are commonly used to indicate composition, with a decrease in MusD reflecting an increase in muscle fat infiltration. The current study explored predictors of MusD acquired using

Body composition measures assessed by bioelectrical impedance analysis and dual-energy X-ray absorptiometry in a sample of Brazilian adults and older adults

Frontiers in Nutrition
IntroductionBioelectrical impedance analysis (BIA) is a common technique for assessing body composition in clinical and epidemiological settings. However, its accuracy is limited compared to reference methods such as dual-energy X-ray absorptiometry (DXA)
