Introduction: Quality of Life is the most studied PRO (patient reported outcome) in cancer patients. With early diagnosis and better treatments in breast cancer, this entity has been transformed in a chronic disease with longer survival. The joint effects of diseases and treatment on quality of life are each day more important to consider in survival patients. Objective: To evaluate Quality of Life, Socioeconomic factors, co-morbidities, and the attendance process impact on quality of life in breast cancer women with different clinical stages attending at the Instituto Mexicano del Seguro Social using the EORCT QLQ-C30 Results: The scores of EORTC QLQ-C30 (v3) were: Global health status / QoL: 73.47 (±20.81), physical functioning 76.98 (±20.85), role functioning 76.60 (±27.57), emotional functioning 64.53 (±26.81), cognitive functioning 74.47 (±26.02), social functioning 84.96 (±23.20), fatigue 31.94 (±25.45), nausea and vomiting 19.49 (±26.93), pain 28.95 (±27.27), dyspnea 15.29 (±24.62), insomnia 35.13 (±32.10), appetite lost 18.04 (±28.75), 18.04 (±28.75), constipation 19.20 (±32.11), diarrhea 12.9 (±24.25), financial difficulties 40.57 (±37.26). The scores with EORTC QLQ-BR23 were: body image 74.84 (±31.69), sexual functioning13.73 (±22.55), sexual enjoyment 32.86 (±36.17), future perspectives 51.69 (±38.00), systemic therapy side effects 30.82 (±20.71), breast symptoms22.85 (±23.49), arm symptoms 27.53 (±24.75), upsert by hair loss 43.80 (±44.01). Conclusions: Clinical stage in breast cancer is associated with differences in the scores from fatigue, nausea and vomiting and financial difficulties according to the evolution of the disease and the physical detriment associated. Socio-demographic features were related role functioning, fatigue and pain in single women with higher scores. © 2011 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

The generalized analytical quadrature filter from a set of interferograms with arbitrary phase shifts is obtained. Both symmetrical and non symmetrical algorithms for any order are reported. The analytic expression is obtained through the convolution of a set of two-frame algorithms and expressed in terms of the combinatorial theory. Finally, the solution is applied to obtain several generalized tunable quadrature filters. © 2011 Optical Society of America.

Laser Shock Processing (LSP) has been proposed as a competitive alternative technology to classical treatments for improving fatigue and wear resistance of metals. We present a configuration and results in the LSP concept for metal surface treatments in underwater laser irradiation at 532 nm and 1064 nm. The purpose of the work is to compare the effect of both wavelengths on the same material. A convergent lens is used to deliver 1.2 J/pulse (1064 nm) and 0.9 J/pulse (532 nm) in a 8 ns laser FWHM pulse produced by 10 Hz Q-switched Nd:YAG laser with spots of a 1.5 mm in diameter moving forward along the work piece. A LSP configuration with experimental results using a pulse density of 2500 pulses/cm2 and 5000 pulses/cm2 in 6061-T6 aluminum samples are presented. High level compressive residual stresses are produced using both wavelengths. It has been shown that surface residual stress level is comparable to that achieved by conventional shot peening, but with greater depths. This method can be applied to surface treatment of final metal products. © 2010 Elsevier B.V. All rights reserved.

The paper aims the electromagnetic simulation of a synchronous impedance transformer using a combination of the finite difference time domain FDTD and the method of lines MoL. The study demonstrates that the hybrid technique called FDTD-MoL can be used for the characterization of passive microstrip circuits. The capability to combine different methods of electromagnetic simulation provides a powerful tool for interpreting the behavior of microwave circuits. The hybrid FDTD-MoL method can characterize microstrip planar structures and is comparable with previous case studies of electromagnetic simulation. © IEICE 2011.

The semicontinuous heterophase polymerization of styrene in the presence of cross-linking and porogen agents was carried out. Latexes with close to 20% solid content, which contained mesoporous nanoparticles with 28 nm in average diameters, up to 0.5 cm3/g in porosity and 6-8 nm in pore diameters were obtained. By varying the monomer dosing rate over the micellar solution, an unexpected direct dependence of instantaneous conversion on the monomer dosing rate was found. This was ascribed to the higher average number of radicals per particle attained in the polymerization at the higher dosing rate, which in turn would arise from the higher gel percentage in the polymer. It is believed that the cross-linked chains prevent encounters between radicals, delaying the bimolecular termination reactions and allowing the existence of more than one radical inside the particles, which in turn increases the propagation rate. © 2014 by the authors.
