    In this review we present a thoroughly comprehensive survey of recent work on modified theories of gravity and their cosmological consequences. Amongst other things, we cover General Relativity, Scalar-Tensor, Einstein-Aether, and Bimetric theories, as well as TeVeS, f(R), general higher-order theories, Horava-Lifschitz gravity, Galileons, Ghost Condensates, and models of extra dimensions including Kaluza-Klein, Randall-Sundrum, DGP, and higher co-dimension braneworlds. We also review attempts to construct a Parameterised Post-Friedmannian formalism, that can be used to constrain deviations from General Relativity in cosmology, and that is suitable for comparison with data on the largest scales. These subjects have been intensively studied over the past decade, largely motivated by rapid progress in the field of observational cosmology that now allows, for the first time, precision tests of fundamental physics on the scale of the observable Universe. The purpose of this review is to provide a reference tool for researchers and students in cosmology and gravitational physics, as well as a self-contained, comprehensive and up-to-date introduction to the subject as a whole.Comment: 312 pages, 15 figure

    INTRODUCTION: In Mexico cancer is a public health burden. Nowadays the health care systems pay special attention to patient's perception and satisfaction of the health care received. Satisfaction with quality of health care has an impact in the adherence to the treatment. OBJECTIVE: To evaluate the satisfaction with the quality of health care received at the IMSS in a group of cancer patients [non Hodgkin lymphoma (NHL), breast and colorectal cancer]. Socio-demographic features, co-morbid diseases, and attendance processes impact on satisfaction are also evaluated. RESULTS: 476 cancer patients were studied: 314 with breast cancer, 92 with NHL and 70 with colorectal cancer. In women with breast cancer the mean score to nurses' interpersonal skills in non-classified disease group and clinical stage III group were: 73.64 +/- 32.53, 90.00 +/- 18.25 respectively (p=0.005), nurses' availability in non-classified and clinical stage III group were: 69.71 +/- 30.25, 89.21 +/- 19.00 respectively (p=0.003). In subjects with NHL the mean scores for doctors' technical skills in clinical stage I and III groups, were: 63.69 +/- 37.78, 80.30 +/- 18.46 respectively (p=0.017), doctors' information provision scores in subject in clinical stage I and IV were: 49.40 +/- 40.75, 79.49 +/- 24.63 respectively (p=0.043). In the group of colorectal cancer patients the mean of the score to exchange of information between clinical stage II and clinical stage III group were 50.00 +/- 41.83, 84.21 +/- 22.37 respectively (p=0.036). Were not observed association between attendance processes features and general satisfaction. CONCLUSIONS: In Mexico 50% of cancer patients are attended at the IMSS. The continued evaluation of the satisfaction with health care received by the health care service users is important to enhance attention's quality.Copyright ?" 2011 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

    [Quality of life in Mexican women with breast cancer at different stages and its association with sociodemographic characteristics, comorbidities and procedural factors at the Mexican Institute of Social Security]

    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 functioning 13.73 (+/- 22.55), sexual enjoyment 32.86 (+/- 36.17), future perspectives 51.69 (+/- 38.00), systemic therapy side effects 30.82 (+/- 20.71), breast symptoms 22.85 (+/- 23.49), arm symptoms 27.53 (+/- 24.75), upset 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.Copyright ?ďż˝ 2011 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).
