OCORRÊNCIA DE Gynandrobrotica caviceps adumbrata Bech. (COLEOPTERA: GALERUCINAE) NA CULTURA DA SOJA EM PIRACICABA, SP

A presença de Gynadrobrotica caviceps adumbrata Bech. foi observada durante as safras de 1990/91 e 1991/92, infestando e danificando folhas de soja, em Piracicaba, SP. Este é o primeiro relato sobre este coleóptero danificando soja no Brasil.<br>During the croping seasons of 1990/91 and 1991/92 the presence of Gynadrobrotica caviceps adumbrata Bech., was observed infesting and promoting damage on soybean leaves in Piracicaba, SP. This is the first report on this beetle damaging soybeans in Brazil

Remediation of Nodularin-R via Electrochemical Removal Using Nanostructured PdO-TiO2@Carbon Anodes

Nodularin is a cyanotoxin commonly produced by cyanobacteria in algal blooms. Among Nodularin variants, the most common is Nodularin-R (NOD-R). This toxin is widely detected in water sources worldwide, being the cause of severe health issues leading to death of animals and humans. Water decontamination from this toxin is of vital importance. Electrocatalytic oxidation of pollutants in water emerged as a promising alternative for the removal of such a toxin. Regarding electrocatalytic oxidation, the low cost of carbon materials, the electrocatalytic properties of metal oxides, and the high surface area of nanostructured systems lead together to highly efficient and viable anodes. The aim of this work is to evaluate graphite carbon cylinder based anodes modified with TiO2 (TiO2@carbon) or PdO and TiO2 (PdO-TiO2@carbon) on the electrocatalytic removal of NOD-R aqueous solutions as well as on the ecotoxicity of the resulting treated solutions. A complete removal of NOD-R could be achieved in 20 min with PdO-TiO2@carbon anode in aqueous medium with 10 mmol L-1 NaCl. No acute toxicity was also observed for Artemia salina exposed to this treated solution for 48 h. © 2018 American Chemical Society

International Nosocomial Infection Control Consortium report, data summary of 50 countries for 2010-2015: Device-associated module

•We report INICC device-associated module data of 50 countries from 2010-2015.•We collected prospective data from 861,284 patients in 703 ICUs for 3,506,562 days.•DA-HAI rates and bacterial resistance were higher in the INICC ICUs than in CDC-NHSN's.•Device utilization ratio in the INICC ICUs was similar to CDC-NHSN's. Background: We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. Methods: During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. Results: Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. Conclusions: Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically
