Incertidumbre y afrontamiento en familiares de personas dependientes del alcohol: apoyo social y espiritualidad / Uncertainty and coping among relatives of alcohol dependent persons: social support and spirituality / Incerteza e enfrentamento em parentes de pessoas dependentes de álcool: apoio social e espiritualidade

Resumen Introducción: La dependencia al alcohol, considerada como una enfermedad crónica, es un detonante de incertidumbre para el familiar de la persona con dependencia, lo cual genera trastornos emocionales negativos. El apoyo social y la espiritualidad son mecanismos de afrontamiento que podrían disminuir la incertidumbre y favorecer el bienestar tanto físico, como psicológico. Objetivos: Determinar la relación y el efecto del apoyo social y la espiritualidad sobre la incertidumbre del familiar de la persona dependiente del alcohol. Métodos: Estudio descriptivo y correlacional, muestra de 135 mujeres pertenecientes a grupos Al-Anon, se utilizaron la Escala de Percepción de Incertidumbre en Padres y Miembros de la Familia (PPUS-FM) de Mishel, el cuestionario MOS-SSS de Sherbourne y Stewart y la Escala de Perspectiva Espiritual elaborada por Reed. Resultados: Se identificó un coeficiente de correlación negativo y significativo de la incertidumbre con el apoyo social (r s= -.356, p <.01) y la espiritualidad (r s= -.216, p <.05). Mediante un modelo de regresión lineal general univariado se determinó que únicamente el apoyo social influye en la disminución de la incertidumbre (β= -.280, t= -3.62, p= .001) con un coeficiente de determinación o varianza explicada del 11.5%, mientras que la espiritualidad no mostró efecto (β= -.041, t= .218, p >.05) sobre la incertidumbre. Conclusiones: El apoyo social es identificado como un mecanismo de afrontamiento efectivo que permitirá al personal de enfermería desarrollar intervenciones dirigidas a reducir la incertidumbre en familiares de personas con algún tipo de dependencia.

Abstract Introduction: Alcohol dependency is a chronic illness which generates uncertainty and other emotional problems among the relatives of persons who suffer alcoholism. Social support and spirituality are some coping mechanisms which could reduce uncertainty and favor the physical and psychological wellbeing. Objective: To determine the relationship and the effect of social support and spirituality on the uncertainty experienced by relatives of alcohol dependent persons. Methods: This is a descriptive and correlational study. The sample was constituted by 135 women members of Al-Anon. The Mishel Scale of Perception of Uncertainty among Parents and Family Members (PPUS-FM), the Sherbourne and Stewart Questionnaire, and the Reed Spiritual Perspective Scale were all used. Results: Significant negative correlation coefficients between uncertainty and social support (r s= -.356, p .05). and spirituality (r s= -.216, p .05). were identified. Using a univariate general linear regression model, it was determined that only social supports reduced uncertainty (β= -.280, t= -3.62, p= .001) with 11.5% of variance explained; while spirituality did not produce any effect (β = -.041, t= .218, p >.05). Conclusions: Social support is identified as a coping mechanism which can be used by nursing staff to develop interventions aimed at reducing uncertainty among relatives of alcohol dependent persons.

Correlation of tumor growth index with early treatment response in cervical carcinoma.

Despite the recent progress in the management of cervical carcinoma, treatment failure is quite common and therefore it is necessary to identify predicting factors for tumor response. It is known that both cell proliferation and apoptosis determine the tumor growth index (TGI) which reflects the overall contribution of gene defects. Here we explored whether the TGI index could be a better predictor of response in comparison to cell proliferation or apoptosis as separate phenomena. Twenty-five patients with cervical carcinoma treated with radiation alone or neoadjuvant chemotherapy plus surgery were analyzed. Cell proliferation and apoptosis determined by PCNA immunohistochemical expression and tumor nucleosomes by ELISA, respectively, were used to calculate the TGI, which was analyzed with regard to early tumor response. Our results show that most patients with a negative TGI had early response suggesting increased tumor sensitivity(p = 0.0186). On the other hand, patients with a positive TGI were more resistant to treatment. TGI was not related to age, clinical stage or tumor size. In conclusion, the results of this study show that the determination of the TGI, but no cell proliferation or apoptosis, as separate events, is able to predict an early treatment response to either radiation or chemotherapy in cervical carcinoma.

Weekly cisplatin/low-dose gemcitabine combination for advanced and recurrent cervical carcinoma.

The aim of this study was to evaluate the activity and safety of the weekly cisplatin/low-dose gemcitabine combination in advanced or recurrent cervix cancer. Fourteen patients were treated with weekly chemotherapy consisting of gemcitabine 100 mg/m2 and cisplatin 33 mg/m2 for a maximum of 18 courses (6 months). The response rate and survival was evaluated. The mean age of patients was 43.4 years, 13 out of 14 had pelvic disease, and most of them received previous irradiation. Eleven patients were evaluated for response and all for toxicity. The mean number of courses delivered was 9.7. Four patients (36%) achieved a partial response and four had stable disease. The most frequent toxicity was nausea/vomiting;myelosuppression was mild and uncommon. At a maximum follow-up of 15 months the median survival was 6 months. This is an active and well-tolerated combination devoid of myelotoxic effects which allows its administration without delays.
