Klebsiella pneumoniae (KP) is an important pathogen involved in serious nosocomial infections all over the world. Here, we describe the first report on a blood-stream infection caused by an OXA- 48/NDM-1 ST101-KP, in Italy. The patient was an Italian woman, transferred from Cairo Hospital to a Neurosurgery ward in Cuneo (IT). The detection described here enhances the need for an effective National infection control strategy in Italy.In Italy, malaria continues to be one of the most common imported parasitoses; therefore, continuous surveillance of epidemiological data and clinical management is needed. In 2016, the National Institute for Infectious Diseases 'Lazzaro Spallanzani' in Rome promoted a retrospective questionnaire-based survey to assess the clinical management of imported malaria cases in Italy in 2015. The questionnaire was sent to 104 Tropical and/or Infectious Diseases Units in the country, and 37 of them filled out and returned the questionnaires. MPP antagonist order A total of 399 malaria cases were reported in 2015, mostly caused by Plasmodium falciparum and imported from Africa. Malaria chemoprophylaxis was correctly used by a minority of patients. Most patients presented with uncomplicated malaria and were treated orally. In severe cases, intravenous artesunate or quinine alone or in combination were administered, although one third of these severe cases received oral treatment. This retrospective survey reveals a lack of homogeneity in management of malaria-imported cases in Italy. Improvement of malaria chemoprophylaxis, standardization of clinical management of malaria cases and harmonization of oral and intravenous drug availability are needed throughout the country.The gut microbiota is a complex and dynamic ecosystem with a strong influence on the host's health. Several factors can modify the gut's bacterial composition, often leading to the onset of intestinal dysbiosis. Therefore, it is essential not only to evaluate the quantitative bacterial changes occurring in the human microbiota but also to characterize relationships existing among all the microorganisms. This study aimed to evaluate the impact of bowel cleansing on the fecal microbiota network by highlighting differences between fecal microflora before and after colonoscopy, and luminal samples during colonoscopy. Fecal and luminal samples, previously analyzed by mean of Next-Generation Sequencing (NGS) for their bacterial abundance, were further processed by a method based on Artificial Neural Network (ANN) architecture. The bowel lavage had a strong effect on the intestinal microbiota network, leading to significant changes in the distribution of different bacterial hubs potentially involved in the microbiota homeostasis. Furthermore, the fecal and luminal microbiota showed a different bacterial network, characterized by distinct microbial hubs. In particular, the latter seemed to be rich in potentially pathogenic bacteria which, in physiological conditions, are counteracted by fecal microorganisms.This study reports our experience with the Accelerate PhenoTM system (ACC) to guide management of patients with sepsis by Gram-negative pathogens. A diagnostic workflow, based on pathogen and resistance genes detection or ACC testing, was applied to 33 patients. Clinical and microbiological data were recorded, and analysis of broad-spectrum agents sparing was performed. Antimicrobial susceptibility results by ACC were available for 28 of 33 patients (84.85%). Among 434 microorganism-antimicrobial combinations, categorical agreement was 97.93%, very major errors 0.23%, major errors 1.15%, and minor errors 0.69%. Time to report (mean ± SD) of ACC results was 27.14 ± 6.90 h from sample collection, significantly shorter (p less then 0.001, Δ = 19.96 h, 95% CI 24.71 - 15.22) than that of the standard method (47.10 ± 11.92 h). A switch from empiric to targeted therapy was observed in 14 of 28 patients (50.0%), duration of empiric therapy was 37.73 ± 19.87 h, with a saving of 5.45 piperacillin/tazobactam and 5.28 carbapenems prescribed daily doses. Considering patients in which de-escalation would have been theoretically feasible, 27.69 prescribed daily doses of piperacillin/tazobactam and 19.08 of carbapenems could had been spared, compared to standard methods. In conclusion, ACC could impact positively on the management of septic patients by Gram-negative pathogens.Disruptions to cardiac tissue microstructure are common in diseased or injured myocardium and are known substrates for arrhythmias. However, we have a relatively coarse understanding of the relationships between myocardial tissue microstructure, propagation velocity and calcium cycling, due largely to the limitations of conventional experimental tools. To address this, we used microcontact printing to engineer strands of cardiac tissue with eight different widths, quantified several structural and functional parameters and established correlation coefficients. As strand width increased, actin alignment, nuclei density, sarcomere index and cell aspect ratio decreased with unique trends. The propagation velocity of calcium waves decreased and the rise time of calcium transients increased with increasing strand width. The decay time constant of calcium transients decreased and then slightly increased with increasing strand width. Based on correlation coefficients, actin alignment was the strongest predictor of pological situations. © The Author(s) 2020. Published by Oxford University Press. All rights reserved.

METHODS We conducted a systematic review of Medline, Embase, and Cochrane Database of Systematic Reviews to identify observational studies assessing the perinatal impacts of biologic in women with inflammatory systemic disease. Findings were meta-analysed across included studies with random-effects models. Crude risk estimates and, where possible, adjusted risk estimates were pooled to determine the impact on results when confounding is addressed. RESULTS Overall, 24 studies were included in the meta-analysis. Meta-analyses of crude risk estimates resulted in pooled odds ratios (OR) for the association of biologic use during pregnancy and the following respective outcomes congenital anomalies (1.30, 95% CI 1.02, 1.67), preterm birth (OR 1.61, 95% CI 1.37, 1.89), and low birth weight (OR 1.
