Portopulmonary hypertension is an uncommon complication of portal hypertension, running a progressive course with a negative prognosis. Reports in pediatric patients are scarce with short follow up. We describe the case of decompensated cirrhosis who developed PoPH and resolved with liver transplantation, remaining asymptomatic after ten years of follow up.

LT1009 is a humanized version of murine LT1002 IgG1 that employs two bridging Ca ions to bind its antigen, the biologically active lipid sphingosine-1-phosphate (S1P). We crystallized and determined the X-ray crystal structure of the LT1009 Fab fragment in 10 mM CaCl and found that it binds two Ca in a manner similar to its antigen-bound state. Flame atomic absorption spectroscopy (FAAS) confirmed that murine LT1002 also binds Ca in solution and inductively-coupled plasma-mass spectrometry (ICP-MS) revealed that, although Ca is preferred, LT1002 can bind Mg and, to much lesser extent, Ba.

The aim of this study is to explore arguments that broaden the understanding of possible links between the organization of nursing care and the structuring of professional identity. For that purpose, some aspects related to these themes are addressed, highlighting issues regarding differences in the concepts of the organization of nursing care and the nursing process, as well as the performance of this activity and its possible impact on the establishment of its relationship with the professional identity. Emphasis is given to the need to stimulate the debate on the subject by nursing professionals involved in the training of human resources and the provision of care, as well as in class entities, in order to deepen understanding of these concepts as significant elements for strengthening our professional identity.

Respiratory melioidosis is a disease presentation of the biodefense pathogen, Burkholderia pseudomallei, which is frequently associated with a lethal septicemic spread of the bacteria. We have recently developed an improved respiratory melioidosis model to study the pathogenesis of Burkholderia pseudomallei in the lung (intubation-mediated intratracheal [IMIT] inoculation), which more closely models descriptions of human melioidosis, including prominent septicemic spread from the lung and reduced involvement of the upper respiratory tract. We previously demonstrated that the Type 3 Secretion System cluster 3 (T3SS3) is a critical virulence determinant for B.

Burkholderia pseudomallei, the bacterial agent of melioidosis, causes disease through inhalation of infectious particles, and is classified as a Tier 1 Select Agent. Optical diagnostic imaging has demonstrated that murine respiratory disease models are subject to significant upper respiratory tract (URT) colonization. Because human melioidosis is not associated with URT colonization as a prominent presentation, we hypothesized that lung-specific delivery of B.

Respiratory disease studies typically involve the use of murine models as surrogate systems. However, there are significant physiologic differences between the murine and human respiratory systems, especially in their upper respiratory tracts (URT). In some models, these differences in the murine nasal cavity can have a significant impact on disease progression and presentation in the lower respiratory tract (LRT) when using intranasal instillation techniques, potentially limiting the usefulness of the mouse model to study these diseases.

This study assessed how well patients who had undergone breast cancer surgery monitored their continuous drainage system after receiving one-to-one instructions at the Mastology Outpatient Clinic of Hospital São Paulo at Federal University of São Paulo. Participants were 79 women who had undergone breast cancer surgery between May 2009 and March 2010, and were using a drain. It was found that the self-care training that the patients received in addition to the strategy used in that training, had a positive effect on their self-monitoring of the continuous drainage, which prevented the drain from clogging, evinced by the percentage of patients who maintained the permeability of the drainage system (84.

The objective of this paper is to report the experience of implementing a model of advanced nursing practice that integrates a clinical nurse specialist into the nursing staff. The authors describe the concept of this model and the process of its implementation in a pediatric oncology reference institution in the city of São Paulo, Brazil. The main result achieved in evaluating the clinical nurse specialist was strengthening of the role of the nurse as a reference professional for the articulation of the various demands of care in assisting the child, adolescent or young adult with cancer and his/her family.

Aims And Objectives: To verify whether early (first post-operative day) or late initiation (after removal of the continuous suction drain) of a functional rehabilitation exercise programme influences the incidence of seroma formation and dehiscence for women after breast cancer surgery.

Background: Benefits of early implementation of an exercise programme initiated with women in the first days following breast cancer surgery are widely known. However, the safe initiation of the exercises is still a controversial issue and some authors correlate early initiation of the exercises with an increase in seroma formation.

Nursing is a specific field of knowledge and social practice that has been consolidated and strengthened as science. In Brazil, it has been developed due to the increase and qualification of strict sense post-graduate programs. This study aims to present a historical review of the strict sense post-graduate nursing courses in Brazil and to reflect on their evolution, progress, challenges and future perspectives.

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.

The present article discusses a qualitative study which aimed to understand the typical of nurses' professional practice caring for patient with cancer in general hospitals. In order to find out the reasons that motivate nurse's action, and to put in evidence what is original, significant, specific and typical about this phenomenon, we have taken into consideration the premises of the philosopher Alfred Schütz, which provide us with subsidies to unveil them. The data collected through semi-structured interviews reported that nurses admit not having the required theoretical knowledge and experience or enough practice to take care of a cancer patient.

Purpose: The antineoplastic agents infusion through peripheral lines may lead to several adverse events such as extravasation that is one of the most severe acute reactions of this sort of treatment. The extravasation prevention and management must be part of a safe and evidence-based nursing care. Due to this fact, two algorithms were developed with the purpose of guiding nursing care to children who undergo chemotherapy through peripheral line.
