Psychometric properties of the SV-RES Resilience Scale in Mexican women with breast cancer / Propiedades psicométricas de la Escala de Resiliencia SV-RES en mujeres mexicanas con cáncer de mama

Abstract Introduction Resilience is an adaptation resource for coping with adversity or high risk, in this case, breast cancer diagnosis. The SV-RES Resilience Scale, created in Chile, is a valid, reliable measure for evaluating healthy behaviors in adversity and could be useful for evaluating resources available to women with breast cancer diagnosis in Mexico. Objective To obtain the psychometric properties of the SV-RES Resilience Scale in Mexican women with breast cancer. Method 114 women with breast cancer attending a cancer care center were included. They answered the self-administered SV-RES Resilience Scale comprising three resources: "I am," "I have," and "I can." The dimensions of the scale were identified through an exploratory factor analysis. Results The scale presented overall internal consistency (Cronbach's alpha of .974), with seven dimensions (identity, satisfaction, links, networks, internal strength, self-efficacy, and affectivity/reciprocity) that accounted for 72.75% of the variance. Discussion and conclusion The SV-RES scale is a valid, reliable measure for assessing resilience in Mexican women with breast cancer. Since it is a short, self-administered, and reliable instrument, it is useful for clinical practice and research in similar populations to identify the resources people have for coping with their medical conditions.

Resumen Introducción La resiliencia es un recurso con que cuentan las personas para afrontar situaciones de adversidad o de alto riesgo en su salud, en este caso, el diagnóstico de cáncer de mama. La Escala de Resiliencia SV-RES fue creada en Chile y constituye una medición válida y confiable para evaluar las conductas saludables en condiciones de adversidad y podría ser útil para evaluar los recursos con que cuentan las mujeres mexicanas con diagnóstico de cáncer de mama. Objetivo Obtener las propiedades psicométricas de la Escala de Resiliencia SV-RES en mujeres mexicanas con cáncer de mama. Método Participaron 114 mujeres con cáncer de mama que acudieron a un centro especializado en atención oncológica, quienes respondieron la Escala Autoaplicable de Resiliencia SV-RES, que consta de tres recursos "Yo soy / Yo estoy"; "Yo tengo" y "Yo puedo". Las dimensiones de la escala fueron identificadas por medio de un análisis factorial exploratorio. Resultados La escala presentó una consistencia global interna (alpha de Cronbach de .974), cuyas siete dimensiones (identidad, satisfacción, vínculos, redes, fortaleza interna, autoeficacia y afectividad/reciprocidad) explicaron en conjunto el 72.75% de la varianza. Discusión y conclusión La escala SV-RES es una medida válida y confiable para evaluar la resiliencia en mujeres con cáncer de mama. Al ser un instrumento breve, autoaplicable y confiable, constituye un instrumento útil para su aplicación en la práctica clínica y en la investigación en poblaciones similares, con el fin de identificar los recursos con que cuenta la población para enfrentar sus padecimientos.

Three Cases of Elderly Women with Breast Cancer treated with Non-operative Methods / 한국유방암학회지

The mainstay of treatment in primary breast cancer is still a radical mastectomy. In the case of advanced breast cancer, preoperative chemotherapy is an alternative treatment method to induce surgical therapy. Although the number of elderly patients with breast cancer is increasing, the knowledge about the possible differences in the biology and clinical outcomes of breast cancer according to age is limited. In addition, elderly patients have difficulties with surgical treatment because of the higher rate of coincident systemic illness, high anesthetic risk and high rate of operation refusals for an operation than those in young patients. As it was well known that elderly patients have better prognoses than younger patients and more estrogen and progesterone receptors in tumor tissue, it was expected that oral chemoendocrine and radiation therapy could be an alternative in elderly patients who refuse surgery. Good results were experienced in our three elderly breast cancer patients when applying these non-surgical treatments.

Development of clinical researches on prevention aromatase inhibitorassociated bone loss by zoledronic acid / 中国临床药理学与治疗学

Aromatase inhibitors(AIs) are standard therpy for postmenopausal women with estrogen responsive breast cancers.By inhibiting the aromatase enzyme,causing decreases in endogenous estrogens,the treatment of Als is responsible for lower bone mineral density(BMD) and increased fractures.Therefore,early recognition, prevention,and/or treatment of AI-induced bone loss is needed.Zoledronic acid is specific inhibitors of osteoclasts and extensively used in bone metastasis patients.Recently, there are several trials evaluating the use of in- travenous zoledronic acid as prevention and treatment of AI-induced bone loss in postmenopausal women with breast cancer.In this article, we aim to review the use of zoledronic acid in this population including the response and safety.
