To report on the management strategies in patients with cancer of unknown primary (CUP) in middle-income countries. We conceived a survey of 20 items concerning the management of patients with CUP in daily clinical practice. Only participants from lower- and higher-middle-income countries, as per the World Bank Classification, were eligible for this study. The indications for the first-line treatment did not differ between the two economic regions, whereas those for second-line treatment were more prevalent in higher-middle-income countries. The use of targeted therapy based on immunohistochemistry alone was higher in lower-middle-income countries, although the access to CUP classifiers was similar between the two regions. Proper recommendations must ensure that the economic burden is minimized and that other benefits outweigh the limited survival benefit achieved in patients with CUP.

Development of a CT radiomics prognostic model for post renal tumor resection overall survival based on transformer enhanced K-means clustering.
Med Phys
January 2025
Department of Oncology, The Affiliated Hospital of Southwest Medical University, Luzhou, China.
Background: Kidney tumors, common in the urinary system, have widely varying survival rates post-surgery. Current prognostic methods rely on invasive biopsies, highlighting the need for non-invasive, accurate prediction models to assist in clinical decision-making.
Purpose: This study aimed to construct a K-means clustering algorithm enhanced by Transformer-based feature transformation to predict the overall survival rate of patients after kidney tumor resection and provide an interpretability analysis of the model to assist in clinical decision-making.

Department of Anesthesiology, Perioperative and Pain Medicine, Alberta Health Services and Cumming School of Medicine, University of Calgary, South Health Campus, 4448 Front St. SE, Calgary, AB, T3M 1M4, Canada.
Purpose: We report the use of a pericapsular nerve group (PENG) cryoneurolysis for longer-term analgesia in a patient with a hip fracture and severe medical comorbidities as an alternative to hip fracture surgery.
Clinical Features: A frail but lucid and fully autonomous 97-yr-old female from an assisted living facility sustained a subcapital fracture of her right proximal femur following a ground level fall. She had significant comorbidities including end-stage respiratory disease.

Methods: A retrospective observational study was conducted in patients admitted between 2019 and 2023 to Hospital St.
Design and Validation of a High-Fidelity Left Atrial Cardiac Simulator for the Study and Advancement of Left Atrial Appendage Occlusion.
Cardiovasc Eng Technol
January 2025
Institute for Medical Engineering and Science, Massachusetts Institute of Technology, MA, Cambridge, USA.
Purpose: Atrial fibrillation (AF) is the most common chronic cardiac arrhythmia that increases the risk of stroke, primarily due to thrombus formation in the left atrial appendage (LAA). Left atrial appendage occlusion (LAAO) devices offer an alternative to oral anticoagulation for stroke prevention. However, the complex and variable anatomy of the LAA presents significant challenges to device design and deployment.
