Global monitoring of antimicrobial resistance based on metagenomics analyses of urban sewage

Antimicrobial resistance (AMR) is a serious threat to global public health, but obtaining representative data on AMR for healthy human populations is difficult. Here, we use meta-genomic analysis of untreated sewage to characterize the bacterial resistome from 79 sites in 60 countries. We find systematic differences in abundance and diversity of AMR genes between Europe/North-America/Oceania and Africa/Asia/South-America. Antimicrobial use data and bacterial taxonomy only explains a minor part of the AMR variation that we observe. We find no evidence for cross-selection between antimicrobial classes, or for effect of air travel between sites. However, AMR gene abundance strongly correlates with socio-economic, health and environmental factors, which we use to predict AMR gene abundances in all countries in the world. Our findings suggest that global AMR gene diversity and abundance vary by region, and that improving sanitation and health could potentially limit the global burden of AMR. We propose metagenomic analysis of sewage as an ethically acceptable and economically feasible approach for continuous global surveillance and prediction of AMR.Peer reviewe

ENDOTHELIAL-TROPIC AND NEPHROPROTECTIVE EFFECTS OF COMBINED ANTIHYPERTENSIVE THERAPY IN PATIENTS WITH TYPE 2 DIABETES MELLITUS

Aim. To assess the effect of the 24-week antihypertensive therapy with fixed-dose drug combination (lisinopril plus amlodipine) on endothelial dysfunction and renal function in patients with arterial hypertension (HT) and diabetes mellitus (DM) type 2.Material and methods. 30 hypertensive patients with DM type 2 (aged 40-65 years) were included into the study. Endothelial function (plasma and vascular components) and renal function were studied.Results. Combined antihypertensive therapy significantly improved parameters of endothelial function in patients with HT and DM type 2: production of nitric oxide (NO) in blood serum and urine increased by 122.8% and 65.8%, respectively. Along with these secretion of endothelin (ET-1) in serum and urine decreased by 26.1% and by 76.1%, respectively, p&lt;0.05. A statistically significant redistribution of patients by type of microcirculation was established: the share of patients with normal type of microcirculation increased by 73.4%. There was a statistically significant reduction of proteinuria and albuminuria by 58% and 43.6%, respectively. The share of patients with chronic kidney disease with an estimated GFR 30-60 ml/min/1.73 m2 decreased by 16.7%.Conclusions. It has been shown that the prescription of a long-term antihypertensive therapy with dose-fixed combination (lisinopril plus amlodipine) is safe and effective for endothelial function improvement, including renal endothelium, with no negative effect on glucose and lipid metabolism in patients with HT and DM type 2.</p

Surveillance Program of Clinical Samples for Polio and Non-Polio Enteroviruses in the Slovak Republic during the 1958&ndash;2020 Period

Enteroviruses (EVs) are associated with a wide spectrum of diseases involving various organs. Our aim was to give a historical overview of the genesis of clinical sample processing for EVs in the Slovak Republic (SR) during the 1958&ndash;2020 period, within the framework of the World Health Organization (WHO) polio program. Further, analyses were made of the data obtained from the archives of processed clinical sample surveillance using statistical methods. We used generalized additive models (GAM) with binomial distribution and logit link functions and an autoregressive moving average (ARMA) to analyze the data obtained during this 63-year period. Our results show trends in the composition of EV strains circulating in the population. Furthermore, statistically significant increasing trends of the non-polio enteroviruses (NPEVs) were observed over the studied time, represented by echoviruses (E) and coxsackieviruses A and B (CVA and CVB), with a cyclical pattern of occurrence. The most prevalent serotype over this period was CVB5, which became significantly more prevalent after 2000. While PVs, CVB1, and CVB3 were present in the second half of the studied period, CVA10, CVA16, E3, E25, and E30 appeared more frequently
