Combıned-Complex Decongestıve Therapy Reduces Volume And Improves Quality Of Lıfe And Functıonal Status In Patıents Wıth Breast Cancer-Related Lymphedema

Background: The aim of this study was to evaluate the effects of complex decongestive therapy (CDT) in patients with breast cancer-related lymphedema (BCRL), in regard to volume reduction, functional status and quality of life (QoL).Methods: Fifty patients with unilateral BCRL were included. The demographic variables focusing on lymphedema were recorded. All patients received combined phase 1 CDT including skin-care, manual lymphatic drainage, multilayer bandaging and supervised exercises, five times a week for three weeks, as a total of 15 sessions. Patients were assessed by limb volumes and excess volumes according to geometric approximation derived from serial circumference-measurements of the limb, prior and at the end of third week. The functional disability was evaluated by quick disability of arm, shoulder and hand questionnaire (DASH). Quality of life was assessed by the European Organization for Research and Treatment of Cancer Core Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) and its breast cancer module (EORTC-QLQ-BR23­).Results: Fifty females with mean age of 53.22±11.2 years were included. The median duration of lymphedema was 12 months. There were 22 patients in stage1, 26 in stage2 and 2 patients in stage3. The mean baseline limb and excess volumes were significantly decreased at the end of therapies (3262±753cm³ vs 2943±646.6cm³ and 31.36±16.5% vs 19.12±10.4%, p=0.000,respectively). The DASH and EORTC-QLQ-C30 and BR23 scores were also decreased significantly (p<0.05). The improvements in volumes were related negatively with the duration of lymphedema,and the stage of lymphedema. Conclusion: In conclusion phase 1CDT in a combined manner performed daily for 3 weeks, greatly reduces the volumes as well as improves the disability and QoL, especially when performed earlier.Trial Registration: 'retrospectively registered’

Influence of Excess Volumes Induced by Re and W on Dislocation Motion and Creep in Ni-Base Single Crystal Superalloys: A 3D Discrete Dislocation Dynamics Study

A comprehensive 3D discrete dislocation dynamics model for Ni-base single crystal superalloys was used to investigate the influence of excess volumes induced by solute atoms Re and W on dislocation motion and creep under different tensile loads at 850 ° C. The solute atoms were distributed homogeneously only in γ matrix channels. Their excess volumes due to the size difference from the host Ni were calculated by density functional theory. The excess volume affected dislocation glide more strongly than dislocation climb. The relative positions of dislocations and solute atoms determined the magnitude of back stresses on the dislocation motion. Without diffusion of solute atoms, it was found that W with a larger excess volume had a stronger strengthening effect than Re. With increasing concentration of solute atoms, the creep resistance increased. However, a low external stress reduced the influence of different excess volumes and different concentrations on creep.
