Background/Aim: The prognosis of a cancer patient is influenced by the tumor-related factors, as well as by various patient-related factors. We evaluated the association between inflammatory and nutritional factors and their outcomes, including the prognosis and therapeutic course, in patients with metastatic breast cancer. Patients and Methods: In this observational retrospective study, we evaluated 35 patients. The inflammatory and nutritional markers before systemic therapy included the lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), monocyte-tolymphocyte ratio (MLR), systemic immune-inflammatory index (SII), systemic inflammatory response index (SIRI), pan-immuno-inflammatory values (PIV), prognostic nutritional index (PNI), Glasgow prognostic score (GPS), and psoas muscle index (PMI). Results: Triple-negative, low PNI, and GPS 2 were correlated with worse overall survival in the univariable analysis. The GPS was the only independent predictor of overall survival [hazard ratio=5.85, 95% confidence interval=1.15-29.68, p<0.01]. The time to treatment failure of first-line therapy in patients with GPS 2 was significantly shorter than that in patients with GPS 0/1 (p<0.01). Conclusion: The GPS was an independent predictive marker for overall survival in patients with metastatic breast cancer. [ABSTRACT FROM AUTHOR]

The effects of poling termination and aging process on the piezoelectric properties at room temperature of 1 mol % Mn-doped Ba(Ti0.96Zr0.04)O3 ceramics with orthorhombic structure have been investigated. It is expected that the substitution of accepter Mn into the Ti0.96Zr0.04 site will result in a defect dipole with an oxygen vacancy and generate an internal field (Ed) in 1 mol % Mn-doped Ba(Ti0.96Zr0.04)O3 ceramics. In order to investigate the effect of the rearrangement of defect dipoles on the piezoelectric properties, the following two investigations have been performed. One is on the relationship between the piezoelectric properties and the change in the poling-termination temperature (TP) around the orthorhombic–tetragonal temperature (TOT). The result shows that piezoelectric properties are related to spontaneous polarizations, and that the rearrangement of defect dipoles is small. The other is on the influence of aging treatment at 70 °C for 24 h on the piezoelectric properties. Above TOT, the piezoelectric properties are almost the same, independent of the TP of the specimen. This result suggests that the change in piezoelectric properties is due to a change in the domain in spontaneous polarizations and that the rearrangement of defect dipoles is also small. The result of domain observation reflection electron microscopy supports the rearrangement of spontaneous polarizations during the aging process. [ABSTRACT FROM AUTHOR]
