The impact of preceptorship on the newly qualified nurse and preceptors working in a critical care environment: An integrative literature review.

Background: Preceptorship has been found to be effective in supporting Newly Qualified Nurses (NQNs) during their transition into challenging environments, particularly in addressing issues related to confidence and anxiety. Effective preceptorship is an element of best practice and essential to support NQNs' transition into the critical care setting. However, the impact of preceptorship on NQNs and their preceptors in critical care units is yet to be completely understood.

Intermittent repeated stress but not ketamine changes mice response to antidepressants.

Discovery of the rapid antidepressant effect of ketamine has been considered one of the most important advances in major depressive disorder treatment. Several studies report a significant benefit to patients that lasts up to 19 days after treatment. However, concerns arise from the long-term use of ketamine, thus a safe and effective strategy for maintaining its antidepressant effect is still necessary.

The association between knowledge about HIV and risk factors in young Amazon people.

Objectives: analyze the association between the level of HIV knowledge among young people from Amazonas region, their sociodemographic profile and infection risk factors.

Methods: cross-sectional analytical study, which used a structured questionnaire containing questions about sociodemographic, behavioral aspects and HIV knowledge. Data were grouped by sex and underwent ordinal and binary logistic regression analysis.

Brazilian guidelines for the pharmacological treatment of idiopathic pulmonary fibrosis. Official document of the Brazilian Thoracic Association based on the GRADE methodology.

Idiopathic pulmonary fibrosis (IPF) is a form of chronic interstitial lung disease of unknown cause, which predominantly affects elderly men who are current or former smokers. Even though it is an uncommon disease, it is of great importance because of its severity and poor prognosis. In recent decades, several pharmacological treatment modalities have been investigated for the treatment of this disease, and the classic concepts have therefore been revised.

Update on the approach to smoking in patients with respiratory diseases.

Smoking is the leading cause of respiratory disease (RD). The harmful effects of smoking on the respiratory system begin in utero and influence immune responses throughout childhood and adult life. In comparison with "healthy" smokers, smokers with RD have peculiarities that can impede smoking cessation, such as a higher level of nicotine dependence; nicotine withdrawal; higher levels of exhaled carbon monoxide; low motivation and low self-efficacy; greater concern about weight gain; and a high prevalence of anxiety and depression.

Apocynin reduces blood pressure and restores the proper function of vascular endothelium in SHR.

This study has evaluated how the vascular endothelium of hypertensive rats chronically treated with apocynin affects acetylcholine (ACh), sodium nitroprusside (SNP), and phenylephrine (PE) action on the nitric oxide (NO) signal transduction pathway in endothelial (EC) and vascular smooth muscle cells. Treatment with apocynin significantly reduced the mean arterial pressure in spontaneously hypertensive rats (SHR). In addition, apocynin improved the impaired ACh hypotensive effect on SHR.

Update on diagnosis and treatment of idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis is a type of chronic fibrosing interstitial pneumonia, of unknown etiology, which is associated with a progressive decrease in pulmonary function and with high mortality rates. Interest in and knowledge of this disorder have grown substantially in recent years. In this review article, we broadly discuss distinct aspects related to the diagnosis and treatment of idiopathic pulmonary fibrosis.

Cytological analysis of bronchoalveolar lavage in patients with interstitial lung diseases and the relation of cytological analysis to fibrosis in high-resolution computed tomography.

Objective: To evaluate the value of differential cytology of bronchoalveolar lavage (BAL) in common interstitial lung diseases (ILDs) and its relation with high-resolution computed tomography (HRCT) fibrosis.

Study Design: A retrospective analysis of BAL from 91 patients. The total and percentage of cells were collected and analyzed according to published guidelines.

Highlights of the Brazilian Thoracic Association guidelines for interstitial lung diseases.

Interstitial lung diseases (ILDs) are heterogeneous disorders, involving a large number of conditions, the approach to which continues to pose an enormous challenge for pulmonologists. The 2012 Brazilian Thoracic Association ILD Guidelines were established in order to provide Brazilian pulmonologists with an instrument that can facilitate the management of patients with ILDs, standardizing the criteria used for the diagnosis of different conditions and offering guidance on the best treatment in various situations. The objective of this article was to briefly describe the highlights of those guidelines.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia accompanied by airflow obstruction.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia with airflow obstruction is a rare form of lung injury. All of the reported cases have been diagnosed by surgical lung biopsy. Only three of the reported cases presented with diffuse interstitial lung opacities on HRCT scans.

Subacute and chronic hypersensitivity pneumonitis: histopathological patterns and survival.

Background: In hypersensitivity pneumonitis (HP), survival can be predicted on the basis of the severity of fibrosis in surgical lung biopsy, but few data are available on the influence of clinical, functional, tomographic and histologic findings on prognosis.

Objectives: To describe the impact on survival of clinical data, histological patterns, and HRCT findings in subacute/chronic HP.

Methods: A retrospective analysis of 103 patients diagnosed with HP submitted to surgical lung biopsy.
