Clinical TrialNon-invasive ventilation in an elderly population admitted to a respiratory monitoring unit: causes, complications and one-year evolution.
To determine the usefulness of non-invasive ventilation (NIV) in elderly patients (≥75) admitted to a respiratory monitoring unit (RMU) during hospitalization and 1 year later in comparison with the results from the younger age group (<75). ⋯ NIV is a good alternative in elderly patients admitted to the hospital with respiratory acidosis. We did not detect differences in mortality during admission between the two groups. The elderly patients were more frequently re-admitted than the younger group in the 6-12 months after hospital discharge. This could be due to their poorer functional state after hospitalization requiring NIV.

[From exclusion to uncertainty: the route to diagnosing idiopathic pulmonary fibrosis].
Idiopathic pulmonary fibrosis (IPF) is a differentiated disease within the idiophatic interstitial pneumonias. IPF is progressive and fibrosing and is limited to the lungs. This entity generally affects persons older than 50 years old and is associated with the radiological and/or histological pattern of usual interstitial pneumonia (UIP). ⋯ There are no specific laboratory alterations. Bronchoalveolar lavage and transbronchial biopsy will not establish the diagnosis of IPF but are useful to exclude other entities. Definitive diagnosis requires: a) exclusion of other, defined clinical entities or diffuse pulmonary diseases of known cause, and b) the presence of a histological pattern of UIP on analysis of pulmonary tissue from surgical biopsy, radiological evidence of the defined pattern of UIP on high-resolution computed tomography, or both.

ReviewInfluence of anti-HBc positive organ donor in lung donor selection.
The risk of hepatitis B virus (HBV) transmission through donor organs with HBsAg(-) and anti-HBc(+) serology has not been extensively studied in lung transplantation. The objectives of this study are to ascertain the influence of the anti-HBc(+) on the acceptance of the lung for transplantation, to comment on the published literature and to suggest an algorithm for action. ⋯ The presence of anti-HBc in the donor influences the decision to accept a lung donor, although there is little information on its repercussions. To date, there has been no reported case of transmission of HBV, but post-transplant anti-HBc seroconversions have been described, which suggests contact with viral particles. Although rare, an anti-HBc(+) donor can harbor a hidden HBV infection. The risk of infection can be reduced with adequate anti-HBs titers or with appropriate pharmacological measures.

MicroRNAs (miRNAs) are small non-coding RNA molecules that negatively regulate gene expression. They actively participate in the modulation of important cell physiological processes and are involved in the pathogenesis of lung diseases such as lung cancer, pulmonary fibrosis, asthma and chronic obstructive pulmonary disease. A better understanding of the role that miRNAs play in these diseases could lead to the development of new diagnostic and therapeutic tools. In this review, we discuss the role of some miRNAs in different lung diseases as well as the possible future of these discoveries in clinical applications.
