Protocol: Can coronary artery calcium score identified on thoracic planning CT scans be used and actioned to identify cancer survivors at high risk of cardiac events: A feasibility study in cancer survivors undergoing radiotherapy in Australia
BMJ Open. 2023 Jul 18;13(7):e072376. doi: 10.1136/bmjopen-2023-072376.ABSTRACTINTRODUCTION: A coronary artery calcium (CAC) CT scan can identify calcified plaque and predict risk of future cardiac events. Cancer survivors undergoing thoracic radiotherapy routinely undergo a planning CT scan, which presents a unique opportunity to use already obtained medical imaging to identify those at the highest risk of cardiac events. While radiation therapy is an important modality for many cancer treatments, radiation dose to the heart in thoracic radiotherapy leads to cardiotoxicity and may accelerate pre-existing atherosclerosis. T...

Sensitivity of a bone-equivalent polymer gel dosimeter for measuring the dose to bone during radiation therapy
In this study, we developed a bone-equivalent polymer gel dosimeter (BPGD) that can measure the dose absorbed by the bone and investigated its sensitivity. The BPGDs were prepared by adding 3.0 mol of calcium hydrogen phosphate dihydrate as a component of bone to an improved dose-sensitive polyacrylamide gelatin and tetrakis hydroxymethyl phosphonium chloride (iPAGAT). One day after preparation, the BPGDs were irradiated with a field size of 15 × 15 cm2 using a 10 MV X-ray beam to evaluate the dose sensitivity, dose-rate dependence, and dose-integration dependence. One day after dose exposure, the BPGDs were scanned using...

Automated coronary artery calcium scoring in patients with breast cancer to assess the risk of heart disease following adjuvant radiation therapy
CONCLUSIONS: The CAC score was a significant predictor of ACE in patients with breast cancer. Although further studies are required, CAC score screening on simulation CT in patients undergoing breast RT can help identify those with high risk for ACE on a per-patient basis.PMID:35870419 | PMC:PMC9307671 | DOI:10.1016/j.breast.2022.07.003

A Calcium Imaging Approach to Measure Functional Sensitivity of Neurons
Methods Mol Biol. 2022;2413:97-106. doi: 10.1007/978-1-0716-1896-7_11.ABSTRACTPain associated with chemotherapy and radiation therapy is one of the most common reasons for discontinuation of these treatments and has a dramatic effect on the quality of life in cancer patients. However, the mechanisms underlying chemotherapy and radiation therapy associated with pain are not well understood. Pain sensations are mediated through sensory neurons whose cell bodies are located in the dorsal root ganglia (DRG). Pain mediators activate these sensory neurons causing an influx of ions, including calcium. One common technique to stud...
