Within the German Gonococcal Resistance Network's (GORENET) Neisseria gonorrhoeae (NG) sample collection, azithromycin-resistant NG isolates increased from 4.3% in 2016 to 9.2% in 2018. We aim to understand this observed increase using whole genome sequencing of NG isolates combined with epidemiological and clinical data. Reduced susceptibility to azithromycin in 2018 was predominately clonal (NG multiantigen sequence typing G12302) and could mainly be attributed to the recently described mosaic-like mtr locus. Our data suggest that, together with horizontal gene transfer of resistance determinants and well-established point mutations, international spread of resistant lineages plays a major role regarding azithromycin resistance in Germany.

Ageism toward older adults, prevalent in contemporary societies, seems to be internalized during childhood and consolidated during adolescence. Although several instruments have been developed to measure adolescents' ageism, they present a number of limitations. read more The study aimed at developing a new instrument, the Adolescents' Ageism Toward Older Adults Scale, and testing its psychometric properties.

A three-phase process was followed The instrument's items were developed empirically from focus groups of adolescents; its content validity was evaluated; and finally, its psychometric properties were tested through a multicenter cross-sectional study involving 575 adolescents.

Exploratory factor analysis of the new scale retained 33 items grouped into 6 factors moodiness, traditionalism, physical deterioration, antitechnologism, sageness, and sociability. Confirmatory factor analysis evidenced a second-order factor structure. Omega coefficients measuring internal consistency were above the cutoff of 0.60 for the 6 factors except for antitechnologism. Intraclass correlation coefficients for the entire scale and for the 6 factors were greater than 0.70, again excepting antitechnologism.

The Adolescents' Ageism Toward Older Adults Scale is a promising measure of adolescents' negative and positive attitudes toward older adults. Its validation highlighted some criticalities that can be resolved by a few modifications. Further testing of the scale should be conducted after these modifications.

While they are known to be harmful to nontarget organisms, the effects of herbicides on the composition and functioning of soil microbial communities remain unclear. Here we show that application of three widely used herbicides-glyphosate, glufosinate, and dicamba-increase the prevalence of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) in soil microbiomes without clear changes in the abundance, diversity and composition of bacterial communities. Mechanistically, these results could be explained by a positive selection for more tolerant genotypes that acquired several mutations in previously well-characterized herbicide and ARGs. Moreover, herbicide exposure increased cell membrane permeability and conjugation frequency of multidrug resistance plasmids, promoting ARG movement between bacteria. A similar pattern was found in agricultural soils across 11 provinces in China, where herbicide application, and the levels of glyphosate residues in soils, were associated with increased ARG and MGE abundances relative to herbicide-free control sites. Together, our results show that herbicide application can enrich ARGs and MGEs by changing the genetic composition of soil microbiomes, potentially contributing to the global antimicrobial resistance problem in agricultural environments.To assess the effects of exposure to extremely low-frequency magnetic fields (ELF-MFs) on MDCK cell lines, experiments were performed in a chamber under controlled conditions (temperature, humidity and CO2). Therefore, the measured physicochemical and electrical changes in the cells are due solely to the magnetic field exposure and not to external factors. A developed sinusoidal magnetic field generator produced the ELF-MFs with a uniform magnetic field and adjustable intensity and frequency. Three experimental indicators were used (i) transepithelial electrical impedance (TEEI); (ii) cell migration and proliferation; and (iii) expression of the proteins of the tight junctions, and changes in the area and shape of the cell nuclei. No significant effects on TEEI values were observed when 10 and 50 G 60 Hz magnetic fields were applied to confluent cell monolayers. There were no significant differences in migration and proliferation of the cell monolayer exposed to 60 Hz magnetic fields10 and 50 G , but a contact inhibition factor was observed. The expression of the CLDN-1 protein decreased by 90% compared with the control, while ZO-1 protein expression increased by 120%. No significant effects were observed in the area and shape of the cell nuclei. Experimentation in a controlled environment, under physiological conditions, ensures that the observed effects were strictly due to exposure to magnetic fields. Different exposure conditions are necessary to determine the impact on TEEI and cell migration-proliferation indicators.

Recent work suggests that having aortic valve surgery in the morning increases risk for cardiac-related complications. This study therefore explored whether mortality and cardiac complications, specifically low cardiac output syndrome, differ for morning and afternoon cardiac surgeries.

The study included adults who had aortic and/or mitral valve repair/replacement and/or coronary artery bypass grafting from 2011 to 2018. The components of the in-hospital composite outcome were in-hospital mortality and low cardiac output syndrome, defined by requirement for at least two inotropic agents at 24 to 48 h postoperatively or need for mechanical circulatory support. Patients who had aortic cross-clamping between 8 and 11 am (morning surgery) versus between 2 and 5 pm (afternoon surgery) were compared on the incidence of the composite outcome.

Among 9,734 qualifying operations, 0.4% (29 of 6,859) died after morning, and 0.7% (20 of 2,875) died after afternoon surgery. The composite of in-hospital mortality and low cardiac output syndrome occurred in 2.
