Medidas de no linealidad en regresión no lineal
Grisales Romero Hugo
Revista Colombiana de Estadística , 1994,
Abstract: Usualmente la extensión de las inferencias de los modelos de regresión lineal al caso no lineal se han hecho obviando el grado de no linealidad y la importancia de la bondad de ajuste en muestras peque as. En este articulo se analizan las medidas de Bates y Watts (1980) y Hougaard (1985) para la validación de la extensión inferencial confrontando esta última con la de Box (1971). Se desarrolló un software (RENOL: Regresión No Lineal) para el hallazgo de estas medidas y con su uso se evaluaron dos conjuntos de datos utilizados en sendas investigaciones exponiéndose las conclusiones pertinentes.

Revista Salud Uninorte , 2010,
Abstract: this paper provides an overview of the state of the art of quality of life among women diagnosed with breast cancer and it describe to various approaches that have been incorporated into the assessment. this aspect is relevant because its related changes in patterns of care that have been implemented especially among people with chronic disease. we conducted a narrative search for scientific articles in indexed databases, journals and texts. it was noted that most of the authors are centered in the concept and multidimensionality of the quality of life and the perception of the individual patient. this assessment is a challenge due to limitations of the instruments that exist for that purpose and the complexity of capturing what patients feel and think after diagnosis. this poses an epistemological dilemma, that is, to assess something subjective which is not quantifiable in nature but their assessment is necessary to analyze the changes in health care. we conclude that in the last decade breast cancer treatment approaches have moved from mere functional support towards a more comprehensive biopsychosocial model. social support networks are an essential element that affects the quality of life of these patients. the health care systems should ensure integral care, focused on early diagnosis and treatment, and continuous improvement of quality of life.

Salas Zapata,Carolina; Grisales Romero,Hugo;
Revista Panamericana de Salud Pública , 2010, DOI: 10.1590/S1020-49892010000700002
Abstract: objective: to determine the quality of life and some associated factors in women diagnosed with breast cancer enrolled in cancer treatment programs in a colombian province. methods: in a cross-sectional study, the whoqol bref domains related to the quality of life of 220 women with breast cancer who were in treatment were analyzed. first, a descriptive analysis was done of the sociodemographic variables included in the study. this was followed by an analysis of the quality-of-life scores of the patients in terms of their demographic, clinical, and social characteristics. finally, some characteristics were identified that, in combination, explained the patients' quality of life. results: the quality of life was better for women with more schooling, those who were beneficiaries of the contributory health system, those who received support from family members, those from high-income groups, and those whose personal beliefs (religious and spiritual) helped them cope with the disease. belonging to a lower-income group and having a skeptical attitude constituted risk factors for obtaining lower quality-of-life scores. conclusions: the quality of life of breast cancer patients was poorer, both in general and in the physical, psychological, social, and environmental domains, in those who came from more humble levels of society. psychosocial intervention, through patient-centered methods, is proposed as a strategy that can improve patients' quality of life, especially that of lower-income women. it is necessary to strengthen strategies that enable patients to cope with the disease, relying on the moral, social, and spiritual support of their environment as the main resource.
El reto de la valoración de la calidad de vida en mujeres con cáncer de mama
Carolina Salas Zapata,Hugo Grisales Romero
Revista Salud Uninorte , 2010,
Abstract: Este artículo brinda una síntesis del estado del arte relacionado con la valoración de la calidad de vida de la mujer diagnosticada con cáncer de mama y describe los elementos que se han incorporado en dicha valoración. Este tema es de gran relevancia debido a los cambios que se vienen implementando en los modelos de atención, especialmente de las personas con enfermedades crónicas. Se realizó una búsqueda narrativa de artículos científicos en bases de datos indizadas, revistas y textos. Se observó que la mayoría de los autores parten de las definiciones de calidad de vida, cuyo eje conceptual es la multidimensionalidad del constructo y la percepción individual de la paciente. Dicha valoración constituye un reto debido a las limitaciones de los instrumentos que existen para tal efecto y la complejidad para captar lo que sienten y piensan las pacientes después del diagnóstico. Además, existe un dilema en términos epistemológicos, al querer valorar algo subjetivo (que por naturaleza no es cuantificable) pero que es necesaria su valoración para analizar los cambios en la atención en salud. Se concluye que en la última década ha habido un fortalecimiento importante relacionado con la atención biopsicosocial del paciente oncológico, trascendiendo lo netamente funcional. Las redes de apoyo social son un elemento fundamental en la calidad de vida de estos pacientes. Los sistemas de salud deben garantizarles una atención integral, enfocada hacia el diagnóstico y tratamiento oportuno, y el mejoramiento continuo de su calidad de vida.
