Sociodemographic Determinants for the Health-Related Quality of Life of Patients with Vascular Amputations as Determined with the Prosthesis Evaluation Questionnaire.

Background: To identify the sociodemographic variables independently related to the different dimensions of the Prosthesis Evaluation Questionnaire (PEQ).

Methods: An observational, cross-sectional study was conducted, with a sample of 61 Spanish vascular amputees (Valencia, Spain). Included in this study are the results of the PEQ and explanatory-sociodemographic variables, as well as a descriptive and analytic analysis.

Influence of Exposure to Chronic Persistent Low-Dose Ionizing Radiation on the Tumor Biology of Clear-Cell Renal-Cell Carcinoma. An Immunohistochemical and Morphometric Study of Angiogenesis and Vascular Related Factors.

Increased angiogenesis is related to boosted growth and malignancy in carcinomas. "Chronic Persistent Low-Dose Ionizing Radiation" (CPLDIR) exposure increases incidence and aggressive behavior of clear-cell renal-cell carcinoma (CCRCC). The aim was to study the biology of angiogenesis, including microvessel density (MVD), in human clear-cell renal-cell carcinomas (CCRCC) originating from a radio-contaminated geographical area (Ukraine) and to compare with similar tumors diagnosed in non-contaminated regions of Europe (Spain, Valencia) and Latin America (Colombia, Barranquilla).

Cross-cultural validation of the Prosthesis Evaluation Questionnaire in vascular amputees fitted with prostheses in Spain.

Background: The lack of specific prosthetic-related outcome instruments for Spanish amputees must be addressed.

Objective: To elaborate a culturally equivalent version of the Prosthesis Evaluation Questionnaire in the Spanish language.

Study Design: Cross-cultural questionnaire validation.
