Sarcopenia (Myosteatosis) at Screening CT Colonoscopy in 79-Year-Old Woman With Subsequent Hip Fracture

Sarcopenia (Myosteatosis) at Screening CT Colonoscopy in 79-Year-Old Woman With Subsequent Hip Fracture: A & B. Image at L1 vertebral level without (A) and with (B) overlay of automated skeletal muscle segmentation (B, red). Intramuscular fat is present within paraspinal muscles (A, yellow circle). Mean muscle attenuation is similar for manually placed ROI (1.8 HU) and automated tool (3.9 HU), being markedly decreased for both approaches. Muscle cross-sectional area is relatively preserved when intramuscular fat is included.

C & D. CT images at L3 level without (C) and with (D) muscle segmentation demonstrate similar findings.

E. Hip radiograph demonstrates left intertrochanteric femoral fracture that occurred when patient fell 2 years later. Patient died 4 years after falling.

Building on prior success combining Cyclin-Dependent Kinase (CDK) inhibitors with hormone therapy to treat breast cancer, researchers are now exploring the potential integration of CDK inhibitors with radiotherapy

Schematic overview of cell cycle regulation, with an emphasis on radiotherapy-induced pathways and CDK/cyclin regulation. In M phase and in G2 resting phase, cancer cells are respectively very sensitive and moderately sensitive to radiation injury, whereas in G1 phase and in S phase, cancer cells are moderately resistant to radiation injury. Irradiation induces G1 and G2 cell cycle checkpoint activation and DNA repair. Most cancer cells are defective in G1 checkpoint, commonly due to the mutations/alterations of the key regulators of the G1 checkpoint, but contain a functional G2 checkpoint.

Figure shows coarse attention maps generated using GradCAM for correctly classified high-grade glioma (HGG), low-grade glioma (LGG), brain metastases (METS), meningioma (MEN), acoustic neuroma (AN), and pituitary adenoma (PA). For each pair, the postcontrast T1-weighted scan, and the GradCAM attention map (overlaid on scan) have been shown.
