Background: Preoperative diagnosis of breast abnormalities is currently the standard of care. A population-based study to determine the use of percutaneous needle biopsy for breast diagnosis in Ontario was performed.
Methods: A total of 17,068 women undergoing breast tissue sampling (percutaneous needle biopsy or surgical excision) for diagnosis between April 1, 2002, and December 31, 2002, and without a previous cancer diagnosis were identified. Univariate and multivariate analyses examined the association of age, residence in a particular local health integration network (LHIN), income quintile, urban or rural residence, primary care provider, any prior mammogram, and prior regular screening mammography, as well as whether the biopsy was initiated by a screening mammogram with different methods of tissue diagnosis.
Results: A total of 10,459 women (61%) underwent percutaneous biopsy for diagnosis. A total of 10,131 women underwent surgery, of whom 6,637 received a benign diagnosis and 3,494 had cancer, for a benign-to-malignant ratio of 1.9:1. Women with cancer were slightly more likely to undergo percutaneous biopsy than women without (64.7% vs. 60.3%). There was variation among LHINs in the use of percutaneous biopsy (range, 24%-72%). Women with the highest incomes, urban residence, a primary care provider, or history of any prior mammography were more likely to receive percutaneous biopsy. On multivariate analysis, age 50 to 69 years, LHIN, urban residence, primary care provider, and screen-initiated evaluation were associated with percutaneous biopsy.
Conclusions: Variation in the use of percutaneous biopsy by factors unrelated to indications for biopsy indicate that strategies to identify and overcome barriers to its use are needed.

Formerly termed or , core muscle injury (CMI) encompasses abnormality of structures within the so-called core, which is essentially the hip, abdomen, and pubis. Compared with data on image-guided procedures of other joints, information regarding procedures performed to address CMI and other disorders of the pubic symphysis is lacking. These procedures can be daunting given the joint's small size, surrounding critical neurovascular structures, and three-dimensional anatomy.

Background: Texture analysis has the potential to deliver quantitative imaging markers. Patients receiving computed tomography (CT)-guided percutaneous bone biopsies could be characterized using texture analysis derived from CT. Especially for breast cancer (BC) patients, it could be crucial to better predict the outcome of the biopsy to better reflect the immunohistochemistry status of the tumor.

Background: In-stent restenosis (ISR) is one of the most significant complications following percutaneous coronary intervention (PCI) in patients with coronary artery disease (CAD). Ferroptosis is a novel cell death mode characterized by iron overload and lipid peroxidation. However, the role of ferroptosis in vascular smooth muscle cells (VSMCs) regulating neointimal formation during restenosis remains unclear.

Background: Cardiovascular diseases and cancer are leading causes of morbidity and mortality. Patients with malignancies are at increased risk for cardiovascular complications including acute coronary syndromes, chemotherapy or radiation therapy related complications and cardiac metastasis.
Case Summary: We present a case of a 47-year-old female with metastatic cancer on immunotherapy presented with anterior ST elevation myocardial infarction followed by emergent percutaneous coronary intervention in the left anterior descending artery.
