Emergence of NDM-1-Producing Nosocomial Isolates in Attica Region of Greece.

Here, we report on the emergence and spread of multidrug-resistant NDM-1-producing isolates from patients hospitalized in the Attica region, Greece, in 2022 to provide data on their resistome, their virulome, the genetic environment of , and their molecular epidemiology. A total of 17 carbapenem-resistant isolates identified as NDM-producers by immunochromatography at the hospital level were sent to the Central Public Health Laboratory, in the frame of the laboratory surveillance of carbapenem-resistant pathogens, for further characterization. The initial screening for genetic AMR determinants was carried out by PCR and the MDR Direct Flow Chip assay.

3.0 T diffusion tensor imaging and fiber tractography of the testes in nonobstructive azoospermia.

Purpose: To assess the role of 3.0 T Diffusion Tensor Imaging (DTI) and Fiber Tractography (FT) of the testes in the work-up of nonobstructive azoospermia (NOA).

Methods: This prospective study included consecutive NOA men and controls.

Diffusion tensor imaging and fiber tractography of the normal epididymis.

Purpose: To evaluate the feasibility of diffusion tensor imaging (DTI) and fiber tractography (FT) of the normal epididymis and to determine normative apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values.

Methods: Twenty-eight healthy volunteers underwent MRI of the scrotum, including DTI on a 3.0 T system.

Emergence and persistent spread of carbapenemase-producing high-risk clones in Greek hospitals, 2013 to 2022.

BackgroundPreliminary unpublished results of the survey of carbapenem- and/or colistin-resistant Enterobacterales (CCRE survey) showed the expansion of carbapenemase-producing (CPKP) sequence type (ST) 39 in 12 of 15 participating Greek hospitals in 2019.AimWe conducted a rapid survey to determine the extent of spread of CPKP high-risk clones in Greek hospitals in 2022 and compare the distribution of circulating CPKP clones in these hospitals since 2013.MethodsWe analysed whole genome sequences and epidemiological data of 310 isolates that were carbapenem-resistant or 'susceptible, increased exposure' from Greek hospitals that participated in the European survey of carbapenemase-producing (EuSCAPE, 2013-2014), in the CCRE survey (2019) and in a national follow-up survey (2022) including, for the latter, an estimation of transmission events.
