Effectiveness and Safety of a Very Low-Calorie Ketogenic Diet on Weight Regain Following Bariatric Surgery.

Purpose: Obesity is one of the major public health problems worldwide and bariatric surgery is considered the gold standard treatment for severe obesity. Although the literature supports the safety and efficacy of the very low-calorie ketogenic diet (VLCKD) in patients with obesity, there is no study analyzing the use in case of failure or weight regain after bariatric surgery. This work has the purpose of assessing the response to a VLCKD (Pnk® method) in this population.

Effects of Resistance Exercise with Instability on Cognitive Function (REI Study): A Proof-Of-Concept Randomized Controlled Trial in Older Adults with Cognitive Complaints.

Background: Activities which simultaneously challenge both physical and cognitive function are promising strategies for promoting cognitive function.

Objective: To examine the effects of resistance exercise with instability and traditional resistance exercise compared with a health education control on cognitive function in older adults with cognitive complaints.

Methods: Sixty-seven participants were randomized to either 12 weeks of thrice-weekly resistance exercise (RE = 23), RE with instability (REI = 22), or a weekly health education control (CON = 22).

Phase Angle Is Moderately Associated With Muscle Quality and Functional Capacity, Independent of Age and Body Composition in Older Women.

Background And Purpose: There is a growing body of evidence indicating that phase angle (PhA) can be used as an indicator of nutritional status, disease prognosis, and mortality risk; however, it is still unknown whether PhA can be used as an explanator of functional capacity and muscle quality in older women. The main purpose of this cross-sectional study was to explore whether PhA is associated with muscle quality and functional capacity in older women, regardless of total and regional body composition.

Methods: A total of 125 older women-66.

Phase angle is related with inflammatory and oxidative stress biomarkers in older women.

Background: The aim of this study was to examine the relation between phase angle (PhA) and inflammatory and oxidative stress biomarkers in older women.

Methods: One hundred and fifty-five physically independent older women participated in this study (67.7±5.

Validation of the concept risk for decreased cardiac output.

Objectives: to validate the concept "risk for decreased cardiac output".

Method: Six of the eight steps suggested in the technique developed by Walker & Avant were adopted to analyze the concept of the phenomenon under study and the proposal made by Hoskins was used for content validation, taking into account agreement achieved among five experts.

Results: the concept "decreased cardiac output" was found in the nursing and medical fields and refers to the heart's pumping capacity while the concept "risk" is found in a large number of disciplines.

[Health care models and the building of nursing knowledge and practice].

This is a reflective paper focused on the origins and main characteristics of the epidemiological and clinical models, their connections with the health care models currently adopted in Brazil, and the construction of Nursing knowledge in this context. From this perspective, the authors propose a re-thinking of Nursing knowledge and practice, pointing out possibilities for expanding the Nursing field, as well as the boundaries and challenges to be overcome by the area professionals.

[Evaluation of nursing care systematization through the phases of nursing process performance and registration in a teaching hospital].

This descriptive study was carried out in a teaching hospital at São Paulo city and had as objective to identify the phases performance and registration of nursing care systematization and the most frequent nursing diagnoses. Data were collected retrospectively from 135 patients records of three units: Cardiology, Adult Infectious Diseases and Neurosurgery, from January to July, 2002. The phases: history, nursing diagnoses, prescription, evolution and assessment were performed and registered in the three units, however, it was verified systematization gaps performance related to nursing diagnoses registered without the realization of nursing history and nursing prescriptions without evolution.

[Classifications and the building up of nursing knowledge].

In the course of this article, knowledge is focused on as a process, a series of continuous transformations. Evolutionary aspects of knowledge in nursing are presented. Considerations are taken into account concerning the human language and its significance as well as the conceptual development and classifications to be used in professional actions.
