Estudo com familiares de pacientes com câncer de mama: abordando conhecimento sobre fatores de risco

Breast cancer (BC) is the most common malignancy in women worldwide, with one million new cases confirmed each year. This study aimed at identifying the knowledge of patients? relatives concerning the risk factors (RF) for BC. It is a descriptive quantitative study carried out in the Chemotherapy Technical Division of a University Hospital in São Paulo state, Brazil, from September to October 2006. Only female (30) relatives were included due to the fact that BC is more frequent in females. The major RF cited were family history for BC 33.3% (10), smoking 16.6% (5), alcoholic-drink consumption 10% (3), animal-fat-rich diet 3.3% (1). Other factors such as not breastfeeding, environmental factors, use of oral contraceptives and hormone-replacement therapy were mentioned by 10% (3) of the relatives. It was concluded that the relatives of patients undergoing chemotherapeutic treatment showed to have little knowledge concerning RF for BC. Hence, it is important to rethink the inclusion of the health education process in the family scenario. This issue reaches far beyond thesimple transmission of information. Healthcare professionals and nurses in particular, must focus on these individuals? social context, values, beliefs and needs.

Assistência em saúde: revisão integrativa do conhecimento produzido à luz da complexidade

This is part of an integrative review whose object of study was the production of knowledge in journals concerning nursing studies that have used the Theory of complexity as a theoretical framework. This study gathers seven articles collected from a literature review of 18 publications found on the databases: Medical Literature Analysis and Retrieval Sistem on-line (MEDLINE), Literatura Latino-Americana e do Caribe emCiências da Saúde (LILACS) and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from 1998 to 2008. In the two former databases, the following combination of key words was used: “complexity theory” and “health” and “nursing”, and in the third: “complexidade” and “saúde” and “enfermagem. Content analysis was the methodological framework that allowed for organizing the knowledge aggregated in the theme: Health Care. It was observed that the Complexity Theory has based the comprehension of the health care process, pointing out the care provider with his practices and the environment.

Dissociation and electrooxidation of primaquine diphosphate as an approach to the study of anti-chagas prodrugs mechanism of action

This paper describes the voltammetric behavior of primaquine as a previous support to the further understanding of the delivery and action mechanisms of its respective synthesized prodrugs. There are few papers describing the drug behavior and most of the time no correlation between oxidation process and pH is done. Our results showed that primaquine oxidation is a one-step reaction involving two electrons with the charge transfer process being strongly pH-dependent in acid medium and pH-independent in a weak basic medium, with the neutral form being easily oxidized.This leads to the conclusion that quinoline nitrogen ring neutralization is a determinant step to the formation of the oxidized primaquine form. The existence of a relationship between the primaquine dissociation equilibrium and its electrooxidation process is shown.This work points the importance of voltammetric methodology as a tool for further studies on quantitative relationship studies between chemical structure and biological activity (QSAR) for electroactive drugs.
