[Risk assessment for pressure ulcer in critical patients].

Bedridden patients are in risk to developing pressure ulcers and represent a priority group to be studied to identify this condition. To reach this goal, specific instruments are used to assess this problem. The objective of this study was to analyze the risk factors to developing pressure ulcers in adult patients hospitalized in ICUs.

Impulsivity and the 5-HTTLPR polymorphism in a non-clinical sample.

Background: Impulsivity has been associated with serotonergic system functions. However, few researchers have investigated the relationship between a polymorphism in the promoter of the serotonin transporter gene (5-HTTLPR) and the different components of impulsivity in a non-clinical population. The aim of this study was to investigate the relationship between a polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) and the different components of impulsivity in a non-clinical population.

[Factors associated to pressure ulcers in patients at adult Intensive Care Units].

The maintenance care of potential organ donors: ethnographic study on the experience of a nursing team.

This ethnographic study aimed to understand a nursing team's experience on the maintenance of potential organ donors. Data were collected through ethnographic interview, participative observation and documental analysis and analyzed in thematic, cultural domain and taxonomical terms. The research enabled us to identify the meaning of brain death, revealing the interrelation between the categories (units, nursing team and patient), which constituted this study main theme: "it is not a person".

[Distance learning in the nursing area: report of an experience].

This study aims at reporting an experience of offering a course in the master program of the Universidad Nacional de Rosário. The purpose is to offer elements for a reflection on a conception of long-distance education, as an adequate and efficient modality of education, aiming at enabling a teaching with quality to a determined clientele. The course was developed in three moments: video-conference, long-distance didactic activities and a seminar.

[Nursing process: sequences in care make a difference].

The emphasis of this qualitative investigation was to get to know the significance system, its values and beliefs through the male nurse's perspective in his confrontation with the new methodological proposal of care in a Hospital Institution. Ethnographic interview and data analysis, which was fundamental in James Spradley's studies, were the methods used for collecting data. From data immersion and inventory approach immerged the following theme: "Sequence in care makes the difference", which constitutes the main purpose of this study, providing us with opportunities to reflect about and reveal an activity that up until now ha been nebulous and reticent in the Brazilian nursing scenario.

[Knowledge and technology: myths of an intensive care center].

This article is a partial result of an ethnographic study that had the purpose to describe the culture of intensive care unit nurses. Considering that the ICU is a subculture of the hospital, and that the professionals share symbols and meanings that were developed through social interactions in the context of Intensive Care, the symbolic interactionism and the ethnographic description were used as a theoretical and methodological basis for this study. The participant observation, the ethnographic interview and the documented analysis were used to understand the process of internalization of the symbolic universe of the ICU.
