Background and objective: Bacterial multidrug resistance is particularly common in Gram-negative bacilli (GNB), with important clinical consequences regarding their spread and treatment options. The aim of this study was to investigate the trend of multidrug-resistant GNB (MDR-GNB) in high-risk hospital departments, between 2000–2015, in intervals of five years, with the intention of improving antibiotic therapy policies and optimising preventive and control practices. Materials and methods: This is an observational, retrospective study performed in three departments of the most important tertiary healthcare unit in the southwestern part of Romania: the Intensive Care Unit (ICU), the General Surgery Department (GSD), and the Nutrition and Metabolic Diseases Department (NMDD). MDR was defined as acquired resistance to at least one agent in three or more antimicrobial categories. Trends over time were determined by the Cochran–Armitage trend test and linear regression. Results: During the study period, a total of 2531 strains of MDR-GNB were isolated in 1999 patients: 9.20% in 2000, 18.61% in 2005, 37.02% in 2010, and 35.17% in 2015. The most significant increasing trend was recorded in the ICU (gradient = 7.63, R² = 0.842, p < 0.001). The most common MDR-GNB in the ICU was isolated from bronchoalveolar aspiration samples. Concerning the proportion of different species, most of the changes were recorded in the ICU, where a statistically significant increasing trend was observed for Proteus mirabilis (gradient = 2.62, R² = 0.558, p < 0.001) and Acinetobacter baumannii (gradient = 2.25, R² = 0.491, p < 0.001). Analysis of the incidence of the main resistance phenotypes proportion identified a statistically significant increase in carbapenem resistance in the ICU (Gradient = 8.27, R² = 0.866, p < 0.001), and an increased proportion of aminoglycoside-resistant strains in all three departments, but more importantly in the ICU and GSD. Conclusion: A statistically significant increasing trend was observed in all three departments; the most significant one was recorded in the ICU, where after 2010, carbapenem-resistant strains were isolated.

The study assessed mRNA expression of podocyte-associated molecules in urinary sediments of patients with type 2 diabetes mellitus (DM) in relation to urinary podocytes, biomarkers of podocyte injury and of proximal tubule (PT) dysfunction. A total of 76 patients with type 2 DM and 20 healthy subjects were enrolled in a cross-sectional study, and assessed concerning urinary podocytes, urinary mRNA of podocyte-associated genes, urinary biomarkers of podocyte damage and of PT dysfunction. We found significant differences between urinary mRNA of podocyte-associated molecules in relation with albuminuria stage. In multivariable regression analysis, urinary mRNA of nephrin, podocin, alpha-actinin-4, CD2-associated protein, glomerular epithelial protein 1 (GLEPP1), ADAM 10, and NFκB correlated directly with urinary podocytes, albuminuria, urinary alpha1-microglobulin, urinary kidney-injury molecule-1, nephrinuria, urinary vascular endothelial growth factor, urinary advanced glycation end-products (AGE), and indirectly with eGFR (p < 0.0001, R2 = 0.808; p < 0.0001, R2 = 0.825; p < 0.0001, R2 = 0.805; p < 0.0001, R2 = 0.663; p < 0.0001, R2 = 0.726; p < 0.0001, R2 = 0.720; p < 0.0001, R2 = 0.724). In patients with type 2 DM there is an association between urinary mRNA of podocyte-associated molecules, biomarkers of podocyte damage, and of PT dysfunction. GLEPP1, ADAM10, and NFκB may be considered additional candidate molecules indicative of early diabetic nephropathy. AGE could be involved in this association.

Background and Objectives: The extent of SARS-CoV-2 infection among a population may be assessed by the presence of serum SARS-CoV-2 antibodies, which indicates previous exposure. The aim of this study was to determine the seroprevalence of SARS-CoV-2 infection in the adult population from Western Romania. Materials and Methods: Samples of 2443 consecutive individuals, referred for routine laboratory investigations, were tested for SARS-CoV-2 antibodies using the Elecsys immunoassay that targets the nucleocapsid protein, for identifying the presence of the total antibodies against SARS-CoV-2. Results: The overall SARS-CoV-2 seroprevalence was 45.60%. SARS-CoV-2 seroprevalence was significantly higher in age group 30–49 years (53.94%) compared to age groups 50–69 years (43.53%) and 70–91 years (30.79%) (p < 0.001, p < 0.001, respectively). No significant difference in seroprevalence was observed between females (44.83%) and males (47.05%). Conclusions: Our data revealed a high seroprevalence of SARS-CoV-2 infection in the adult population from Western Romania and indicate the rapid and significant spread of the virus. The estimated prevalence of 45.60% was 6 times higher than the rate of confirmed COVID-19 cases reported in the study area. This indicates the magnitude of virus transmission in the community.

Background: A benzotriazole is a heterocycle frequently used in medicinal chemistry to obtain potent drug candidates, including anticancer agents. Nonetheless, the available literature lacks a comprehensive review of the in vitro and in vivo studies regarding these derivatives. Thus, our study aims to review the preclinical evidence on benzotriazole derivatives that showed potential as anticancer candidates, focusing on the cytotoxicity, mechanisms of action, structure–activity relationship, and methodological rigor of the included studies. Methods: We searched PubMed, Scopus, and Web of Science and included 41 studies in our analysis following the selection process. Additionally, we assessed the risk of bias using the QUIN tool for in vitro and the SYRCLE tool for in vivo studies in order to assess the methodological rigor of the included studies. Results: The benzotriazole derivatives were classified according to their structure in four classes, namely N-derivatives, C-derivatives, fused derivatives, and organometallic compounds. The in vitro results showed that certain derivatives, such as halogen, alkyl-aryl, or natural-base hybrids, can have superior cytotoxicity compared to parent molecules, exerted through multiple mechanisms, such as apoptosis and cell cycle arrest. Additionally, the in vivo analysis highlighted that benzotriazole derivatives can reduce tumor mass in a dose-dependent manner, with only a slight degree of hepatotoxicity reported in one case. However, histopathological data were generally absent or limited and based on a very limited number of in vivo studies. Conclusions: Overall, benzotriazole derivatives remain promising candidates for cancer treatment. However, limited mechanistic and toxicity data, as well as the moderate risk of bias identified across studies, may limit our assessment. Therefore, future studies should employ more rigorous methodologies and explore the underlying anticancer and toxicity mechanisms to fully assess the therapeutic potential of benzotriazole derivatives.
