Parastomal hernia: an overview
Br J Nurs. 2023 Sep 7;32(16):S22-S30. doi: 10.12968/bjon.2023.32.16.S22.ABSTRACTParastomal hernia (PH) is one of the most frequent ostomy complications, and the reported incidence in the literature is highly variable. As highlighted by the Association of Stoma Care Nurses UK, this complication develops mainly in children and older men over 70, but many predisposing factors are related to the individual patient and surgery. There is no standardised system for assessing PH. The main assessment techniques include objective examination, ultrasound scan and computed tomography. Prevention is based on various interventions by su...

Propagation-based phase-contrast imaging of the breast: image quality and the effect of X-ray energy and radiation dose
CONCLUSION: This study demonstrates superior image quality of PB-CT over AB-CT, with X-ray energy playing a crucial role in determining image quality parameters.ADVANCES IN KNOWLEDGE: Our findings reveal that standard dose PB-CT outperforms standard dose AB-CT across all image quality metrics. Additionally, we demonstrate that low dose PB-CT can produce superior images compared to standard dose AB-CT in terms of CNR/Res and vis.PMID:37665247 | DOI:10.1259/bjr.20221189

Air embolism after CT-guided localization of pulmonary ground-glass nodules
CONCLUSION: The incidence of AE related to CT-guided localization of GGNs was 0.5%, which was significantly higher than expected. Post-localization whole thoracic CT should be performed and observed carefully so as to avoid missed AE and delayed treatment.ADVANCES IN KNOWLEDGE: The incidence of AE related to CT-guided localization of GGNs was 0.5%. In order to timely detect AE, whole thoracic CT scan rather than local CT in the lesion area should be performed after localization. A small amount of AE may be missed if the post- localization CT images are not carefully observed.PMID:37660366 | DOI:10.1259/bjr.20220583

Multimodal Imaging-based material mass density estimation for Proton therapy using supervised deep learning
CONCLUSIONS: The proposed PDMI framework can generate accurate mass density maps using MRI and DECT images. The supervised learning can further enhance model efficacy, making PRN-MR-DE outperform RN-MR-DE. The patient investigation also shows that the framework can potentially improve proton range uncertainty with accurate patient mass density maps.ADVANCES IN KNOWLEDGE: PDMI framework is proposed for the first time to inform DL models by physics insights and leverage the information from MRI to derive accurate mass density maps.PMID:37660372 | DOI:10.1259/bjr.20220907
