Evaluation of a fast kV switching dual energy CT in deriving relative stopping power using tissue equivalent phantoms of various sizes

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Dual energy CT (DECT) has been demonstrated to improve relative stopping power (RSP) estimation with knowledge of the effective atomic number (Zeff${Z_{{\mathrm{eff}}}}$) and relative electron density (RED). A fast kV switching DECT has been developed and it is necessary to quantify the accuracy of RSP prior to clinical use ...

Identification of Clinically Distinct Clusters in Patients With Severe COPD Using Circulating Blood Cell Population Parameters

open access: yesRespirology, Volume 31, Issue 2, Page 141-151, February 2026.
This study investigated whether blood cell population data, in addition to cell counts, can identify clinically relevant COPD subgroups. Four distinct inflammatory profiles were identified with distinct clinical characteristics. Cell population data have the potential to provide additional insights beyond inflammatory cell counts and improve patient ...

Changes in Components of Sarcopenia Diagnostic Criteria Throughout the Surgical Treatment of Oesophagogastric Cancer Surgery: A Prospective Longitudinal Study

open access: yesJournal of Human Nutrition and Dietetics, Volume 39, Issue 1, February 2026.
ABSTRACT Introduction Low skeletal muscle is prevalent and associated with poorer outcomes after oesophagogastric (OG) cancer surgery. However, sarcopenia, including strength and function, is less commonly assessed. Therefore, we aimed to describe the prevalence of sarcopenia and changes in diagnostic criteria within 1 year of OG cancer surgery ...

Clinical Characteristics and a New Classification System of Mono‐Segmental Thoracic and Lumbar Nonfusion in Patients With Ankylosing Spondylitis

open access: yesOrthopaedic Surgery, Volume 18, Issue 2, Page 270-278, February 2026.
In regard to the mono‐segmental thoracic and lumbar nonfusion in patients with ankylosing spondylitis, we built a new classification system based on CT and MRI data and describe its clinical distribution characteristics and occurrence risk factors for the first time. ABSTRACT Study Design Retrospective cohort study.

Investigating the association between osteopenia and bowel perforation through a multicenter radiologic analysis

open access: yesScientific Reports
Anecdotal evidence from preliminary observations has noted multiple instances where osteoporosis is present in elderly patients before the clinical detection of bowel disease, even in the absence of overt gastrointestinal symptoms. However, any potential
