One-year longitudinal association between changes in aortic regional morphology and muscle mass in cancer
Abstract Cancer confers the risk for cardiovascular diseases. This longitudinal study aimed to explore the relationship between changes in aortic morphology and muscle mass in cancer. One hundred patients with cancer who underwent thoracoabdominal enhanced computed tomography (CT) at baseline and 1-year follow-up were retrospectively included. Aortic diameter and tortuosity were assessed using CT. Skeletal muscle mass was also evaluated. Pearson correlation analysis and multivariate-adjusted regression models were used to explore the relationship between changes in aortic morphology and muscle mass. Thirty-six patients were male. The average patient age was 57.3 ± 11.3 years. Breast cancer was the most common malignancy. A significant increase in aortic diameter and tortuosity and a decrease in muscle mass were observed. Aortic morphological changes were correlated with changes in muscle mass, diastolic pressure, and high-density lipoprotein cholesterol and C-reactive protein levels. In the fully adjusted multivariable regression analysis, a one-unit increase in muscle mass change was associated with a decrease of 0.503, 0.382, 0.241, 0.174, and 0.163 mm in the diameter of the L1-L5 aortic segments, respectively; a 0.020 decrease in aortic tortuosity; a 0.017 decrease in descending thoracic tortuosity; and a 0.016 decrease in abdominal aortic tortuosity. Increased muscle mass helps maintain aortic morphology in cancer, suggesting that muscle loss is a key factor in increased cardiovascular risk. Muscle might be an important therapeutic target to improve cancer patients’ prognosis.

High gain and wideband hybrid optical amplifier using bismuth-doped and neodymium-doped fibers for E-band applications
Abstract A hybrid dual-stage bismuth-doped fiber and neodymium-doped fiber amplifier with high optical gain and extended bandwidth of operation in the E-band is demonstrated. The amplifier features a maximum gain of 43 dB, output power of 372 mW, and a minimum noise figure of 5.5 dB, and operation wavelength range of 1397–1472 nm, enabled by 153-m of bismuth-doped fiber and two 7-m lengths of neodymium-doped fiber. The demonstration shows the possibility of achieving improved gain bandwidth by combining fiber amplifiers with overlapping gain spectra in the E-band.
