Noninvasive mechanical ventilation (NIMV) was created for patients who needed noninvasive ventilator support, this procedure decreases the complications associated with the use of endotracheal intubation (ETT). The application of NIMV has acquired major relevance in the last few years in the management of acute respiratory failure (ARF), in patients with hypoxemic and hypercapnic failure. The main advantage of NIMV as compared to invasive mechanical ventilation (IMV) is that it can be used earlier outside intensive care units (ICUs). The evidence strongly supports its use in patients with COPD exacerbation, support in weaning process in chronic obstructive pulmonary disease (COPD) patients, patients with acute cardiogenic pulmonary edema (ACPE), and Immunosuppressed patients. On the other hand, there is poor evidence that supports the use of NIMV in other pathologies such as pneumonia, acute respiratory distress syndrome (ARDS), and during procedures as bronchoscopy, where its use is still controversial because the results of these studies are inconclusive against the decrease in the rate of intubation or mortality.

Various concentrations of culture filtrates from Fusarium subglutinans were tested for their effect on in vitro multiplication of plantlets and regeneration from calli of pineapple. The cultivars tested were the resistant Perolera and Spring and the susceptible Perola and Smooth Cayenne. The culture filtrate reduced shoot formation of in vitro plantlets and regeneration of plants from calli derived from the susceptible cultivars but plantlets and calli from resistant plants showed resistance. These results show the potential for culture filtrates of F. subglutinans to provide a method of in vitro screening of pineapple for resistance to the pathogen.
