Investigation of pelvic floor influence on prostate displacement in image‐guided radiotherapy

The Prostate, Volume 85, Issue 2, Page 123-129, February 2025.
Abstract Purpose The uncertainty of target location during prostate cancer radiotherapy plays an important role in accurate dose delivery and radiation toxicity in adjacent organs. This study analyzed displacement correlations between the prostate and pelvic floor.

Pressure Ulcer Categorisation using Deep Learning: A Clinical Trial to Evaluate Model Performance [PDF]

arXiv, 2022
Pressure ulcers are a challenge for patients and healthcare professionals. In the UK, 700,000 people are affected by pressure ulcers each year. Treating them costs the National Health Service {\pounds}3.8 million every day. Their etiology is complex and multifactorial. However, evidence has shown a strong link between old age, disease-related sedentary

Time‐dependent bladder activity changes in streptozotocin‐induced female diabetic rats

Physiological Reports, Volume 13, Issue 4, February 2025.
Diabetic bladder dysfunction is characterized by storage and voiding bladder activity changes in the early stages that induces overactive bladder and underactive bladder in the late phase; this turning point occurs at 8 weeks after diabetes. Abstract This study aimed to investigate the long‐term physiological and morphological changes in the bladders ...

In silico tools for mechanical analysis of extra‐ and intra‐luminal artificial urinary sphincters

BJUI Compass, Volume 6, Issue 1, January 2025.
Abstract Objectives To analyse and compare the functionality of extraluminal and intraluminal artificial urinary sphincters (AUSs), an in silico procedure has been defined and applied. Design and reliability assessments of the AUS are typically performed using a clinical approach, which does not provide data on mechanical stimulation of urethral ...
