Infections due to multidrug resistant Gram-negative pathogens are of great concern worldwide, as they are frequently associated with high mortality and morbidity rates. The occurrence of Pseudomonas spp. producing Klebsiella pneumoniae carbapenemases (KPCs) imposes a great challenge through treatment course of bloodstream infections (BSIs). Pseudomonas putida has been recognized as an emerging pathogen of healthcare associated infections (HAIs). Therefore, we aimed to report a case of a non-fatal case of peripheral line associated BSI (PLA-BSI) in an immunocompromised host due to P. putida harboring blaKPC-2 gene in Brazil. A P. putida isolate was recovered from a blood culture of a 72-year-old man admitted at a University Hospital, identified by BD Phoenix™ 100 (Becton, Dickinson and Company), causing PLA-BSI. The species identification was confirmed by Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) and resistance to carbapenems were confirmed by Epsilometer test (E-test®). Additionally, the presence of important carbapenemases genes (blaKPC, blaNDM, blaOXA-48-like, blaSPM, blaIMP, blaVIM) was investigated by Polymerase Chain Reaction. The bacterial isolate was confirmed as meropenem resistant P. putida harboring blaKPC-2 gene.Thereofre, these fidings suggest that P. putida can work as a reservoir for resistance genes as this bacterium has the ability to disseminate through water-fluids inside hospital and community settings. Moreover, this paper highlights that a frequent and worldwide disseminated mechanism of resistance (blaKPC-2) is currently occurring among uncommon agents of BSI.
Objective: To determine the proportion of patients with asthma with misperception of poor control of their disease. Methods: A cross-sectional study with a convenience sample of patients with asthma and aged ≥18 years. Asthma control was assessed by the Asthma Control Test and the Global Initiative for Asthma questionnaire. The Kappa coefficient was used to analyze the agreement between the results of these tests and the patients' perception of asthma control, defined by the response to one question of the Asthma Control Test: "How do you evaluate your asthma control during the last 4 weeks?". Results: Among the 71 patients aged 19 to 81 years and a mean of 57.7±13.9 years, there were 27 (38%) controlled, according to the Asthma Control Test, and 18 (25.3%) using the Global Initiative for Asthma questionnaire. The Kappa coefficients of the results of these tests and the perception of control by the patients were 0.4 and 0.29, respectively. Among the 41 (57.7%) patients who considered themselves controlled, 18 (43.9%) had a misperception of their poor control, as per the Asthma Control Test, and 25 (61%) by the Global Initiative for Asthma. Conclusion: Applying the Asthma Control Test, it was observed that almost half of the participants had a misperception of their poor control of the disease and, according to the Global Initiative for Asthma questionnaire, more than half of the sample did not notice the lack of asthma control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
