Assessment of the efficacy of Umonium38 on multidrug-resistant nosocomial pathogens.
INTRODUCTION: We investigated the efficacy of a biocide Umonium38 on multidrug-resistant strains by comparison with a chloride derivative (Decs). METHODS: In vitro susceptibility tests were performed by agar diffusion disk and results were interpreted according to Clinical and Laboratory Standards Institute (CLSI). In vitro antibacterial efficacy of Umonium38 and Decs over selected strains was evaluated according to European Standards protocol with or without organic substance. RESULTS: In vitro tests with Umoniumnr at 2.5% concentration demonstrated an overall drop in microbial and yeast charges after 5 min. contact without organic substance. The same results were obtained in presence of organic substance. In vitro tests with chloride derivative at 5% without organic substance also resulted in overall drop in bacterial and mycotic charges. Conversely, in presence of organic substance, the hypochlorite reduced the initial 10 UFC/ml to 10 UFC/ml for all bacterial strains with a decrease of 4 log except for Enterococcus faecalis and Candida albicans whose reduction was 2 and 1 log units respectively. DISCUSSION: The organic substance in water requires large use of oxidising disinfectants (chloride, ozone) implying in the need for higher-than-standard concentrations. The disinfecting effect of chloride is only visible when the "requirement" of organic substance has been met. By contrast, Umonium38 behaves like a powerful biocide even in presence of organic substance, as it is not "consumed" by possible organic residues. CONCLUSIONS: Umonium38 resulted beneficial and effective. It is to be stressed, however, that all these experiments were in vitro tests and still requires validation from a correct use of clinical practice

Resveratrol Reverts Tolerance and Restores Susceptibility to Chlorhexidine and Benzalkonium in Gram-Negative Bacteria, Gram-Positive Bacteria and Yeasts
The spread of microorganisms causing health-care associated infection (HAI) is contributed to by their intrinsic tolerance to a variety of biocides, used as antiseptics or disinfectants. The natural monomeric stilbenoid resveratrol (RV) is able to modulate the susceptibility to the chlorhexidine digluconate (CHX) biocide in Acinetobacter baumannii. In this study, a panel of reference strains and clinical isolates of Gram-negative bacteria, Gram-positive bacteria and yeasts were analyzed for susceptibility to CHX and benzalkonium chloride (BZK) and found to be tolerant to one or both biocides. The carbonyl cyanide m-chlorophenylhydrazine protonophore (CCCP) efflux pump inhibitor reduced the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of CHX and BZK in the majority of strains. RV reduced dose-dependently MIC and MBC of CHX and BZK biocides when used as single agents or in combination in all analyzed strains, but not CHX MIC and MBC in Pseudomonas aeruginosa, Candida albicans, Klebsiella pneumoniae, Stenotrophomonas maltophilia and Burkholderia spp. strains. In conclusion, RV reverts tolerance and restores susceptibility to CHX and BZK in the majority of microorganisms responsible for HAI. These results indicates that the combination of RV, CHX and BZK may represent a useful strategy to maintain susceptibility to biocides in several nosocomial pathogens
Práticas de produção, armazenamento e utilização do plasma rico em plaquetas e produtos relacionados no Brasil: estudo transversal
Introduction: Platelet-rich plasma (PRP) is a technology with potential application in several areas of Medicine and Dentistry. The high variability observed during the production process imposes a challenge for the regulation of its production and use. Objectives: To evaluate current practices of production, storage and use of platelet-rich plasma and related products in Brazil, allowing the identification of operational variability throughout these processes. Method: Crosssectional study with data collection carried out by using a self-applied electronic questionnaire,with protection of anonymity. Questions were defined based on a literature review and consultation with a specialist in the field. The study questionnaire was sent to researchers and professionals who are producing PRP identified by different strategies, such as previous participation in events and publications in the area. Results: 64 responses were obtained, with 36 complete responses (56.3%) and 28 partial responses (43.7%). The rate of respondents could not be calculated, considering the means for dispatching the questionnaire. For PRP, there was a predominance of use of protocols with double centrifugation and platelet activation by different methods. Most respondents reported using PRP in the areas of orthopedics, physiatry and sports medicine. For fibrin-rich plasma (PRF), there was a predominance of responses using a single centrifugation protocol, without the use of platelet activation methods. Most respondents indicate the use of PRF in areas of dentistry. Variability of procedures and usage profile were observed for all platelet concentrates. Analyses were carried out comparatively according to the three main types of platelet concentrates. Conclusions: Findings corroborate the need to develop regulatory norms aiming at reducing variability and at promoting safety along the production and use of platelet concentrates.Introdução: O plasma rico em plaquetas (PRP) é uma tecnologia com potencial aplicação em diversas áreas da medicina e odontologia.

Predicting Alzheimer’s disease severity by means of TMS–EEG coregistration
Clinical manifestations of Alzheimer's disease (AD) are associated with a breakdown in large-scale communication, such that AD may be considered as a “disconnection syndrome.” An established method to test effective connectivity is the combination of transcranial magnetic stimulation with electroencephalography (TMS–EEG) because the TMS-induced cortical response propagates to distant anatomically connected regions. To investigate whether prefrontal connectivity alterations may predict disease severity, we explored the relationship of dorsolateral prefrontal cortex connectivity (derived from TMS–EEG) with cognitive decline (measured with Mini Mental State Examination and a face–name association memory task) in 26 patients with AD. The amplitude of TMS–EEG evoked component P30, which was found to be generated in the right superior parietal cortex, predicted Mini Mental State Examination and face–name memory scores: higher P30 amplitudes predicted poorer cognitive and memory performances. The present results indicate that advancing disease severity might be associated with effective connectivity increase involving long-distance frontoparietal connections, which might represent a maladaptive pathogenic mechanism reflecting a damaged excitatory–inhibitory balance between anterior and posterior regions
