Introduction: Bloodstream infections are the most severe infections that cause the highest mortality rate, especially in patients admitted to the intensive care unit (ICU). In this study, we aimed to analyze the distribution, resistance patterns and prevalence of MDR (multidrug-resistant) pathogens isolated in blood samples collected from patients with severe invasive infections hospitalized in the ICU. Methods: A retrospective study of bacterial pathogens was performed on 490 patients admitted to the ICU between 2017 and 2020. The resistance patterns were analyzed using Vitek 2 Compact system. Results: In total, 617 bacterial isolates were obtained. Four hundred and twenty-seven isolates (69.21%) were Gram positive and 190 isolates (30.79%) were Gram negative bacteria. The most frequently isolated micro-organisms identified in the blood samples for the entire period (2017– 2020) were Coagulase-negative staphylococci (CoNS) (318– 51.54%), followed by Klebsiella pneumoniae (70– 11.34%), Methicillin-Resistant Staphylococcus aureus (MRSA) (58– 9.40%), Acinetobacter baumannii (45– 7.29%) and Enterococcus faecalis (42– 6.80%). The number of Klebsiella pneumoniae strains significantly increased in 2020, compared to the previous year (p < 0.05). The Acinetobacter baumannii prevalence was significantly higher in the age group of 20– 64 years (10.89%) and over 65 years (3.53%) (p < 0.001). The difference between the prevalence of CoNS in the elderly (67.84%) and in adults (20– 64 years) (52.47%) was also statistically significant (p < 0.001). High rates of MDR were found for Acinetobacter baumannii (97.77%), Pseudomonas aeruginosa (65%), Klebsiella pneumoniae (50%), Enterococcus faecalis (47.61%) and MRSA (46.55%). More than 60% of the Klebsiella pneumoniae strains were found to be resistant to carbapenems. Conclusion: The study revealed an alarming prevalence of MDR strains isolated in blood samples of the patients admitted to the ICU, indicating the necessity of consistent application of the measures to control.

Background/Objectives: In this research, we aimed to analyze the trend of the antimicrobial resistance pattern of Gram-negative isolated in blood samples collected from patients with severe invasive infections hospitalized in the intensive care unit in selected periods during and after COVID-19. Methods: A retrospective study of bacterial pathogens was performed on 481 patients admitted to the ICU between 2020 and 2023. The resistance patterns were analyzed using the Vitek 2 Compact system. Results. A total of 686 Gram-negative bacterial isolates were obtained. The most frequently detected Gram-negative pathogens were Klebsiella spp. (30.91%), Acinetobacter spp. (24.64%), and Escherichia coli (18.95%). Almost 50% of all the pathogens were multidrug-resistant, with a statistically significant increase post-pandemic (p < 0.05). Post-pandemic, the study highlighted a significantly higher percentage of the Klebsiella strains (p < 0.05), and a significant increase in the antibiotic resistance rate against colistin (p < 0.001) and tigecycline (p = 0.005). A very high percentage of MDR Acinetobacter spp. isolates was found, with a significant increase in the antibiotic resistance rate against colistin (p < 0.001). A significantly lower resistance was recorded for the Escherichia coli strains in the case of ceftazidime (p = 0.03) and aminoglycosides (gentamicin—p = 0.01, amikacin—p < 0.001). An increase in the percentage of carbapenem-resistant Klebsiella spp., Acinetobacter spp., and Enterobacter spp. strains was observed, and a significant decrease in the in the case of Proteus spp. (p = 0.01). Conclusions: Our findings revealed a statistically significant increase in the resistance rate to last-line antibiotics and in the percentage of MDR Gram-negative strains isolated in the blood samples in the post-COVID-19 era.

We aimed to determine the trend of the antimicrobial resistance pattern of pathogens isolated in samples collected from patients hospitalized in the intensive care unit (ICU) in selected periods before and after COVID-19. A retrospective study of bacterial pathogens was performed on 1267 patients. Positive bacterial culture data from 1695 samples from the pre-COVID-19 period and 1562 samples from the post-COVID-19 period were obtained. The most frequently isolated bacteria in both periods were Staphylococcus aureus and Klebsiella spp. The resistance rates of Klebsiella spp. Significantly increased against colistin (0.38% to 20.51%), gentamicin (44.62% to 64.85%), and aztreonam (56.35% to 3.60%). There was a significant increase in the resistance rate against colistin for E. coli strains (4.69% to 32.46%) and for Acinetobacter sp. strains (3.37% to 18.09%). More than 50% of the Staphylococcus aureus strains were MRSA, with statistically significant increases in the antimicrobial resistance rate against doxycycline (40.08% to 51.72%), linezolid (0.22% to 3.13%), rifampicin (53.16% to 64.93%), and teicoplanin (26.31% to 53.40%). The study revealed a significantly increasing trend in the antimicrobial resistance rate of Gram-negative pathogens against certain antibiotics, including those used only in cases where there are no other therapeutic options.

In this study, we aimed to determine the trend of antimicrobial resistance pattern of pathogens isolated in samples collected from patients hospitalized in the intensive care unit (ICU), in selected periods before and after COVID-19. A retrospective study of bacterial pathogens was performed on 1267 patients. The resistance patterns were analyzed using Vitek 2 Compact system. Positive-bacterial culture data of 1695 samples from pre-COVID-19 period and 1562 from post-COVID-19 period were obtained. The most frequently isolated in both periods were Staphylococcus aureus and Klebsiella spp. Klebsiella spp. had a statistically significant increase in resistance rates in the post COVID-19 period, against colistin, gentamicin and aztreonam. For E. coli strains, it was registered a significant increase against colistin and a significant decrease against levofloxacin and imipenem. For Acinetobacter spp. strains it was observed a significant increase against colistin. More than 50% from the Staphylococcus aureus strains were MRSA with statistically significant increases in antimicrobial resistance rate in the post-COVID-19 period against doxycycline, linezolid, rifampicin and teicoplanin. The study revealed a significantly increasing trend of the antimicrobial resistance rate of Gram-negative pathogens (Klebsiella spp., Acinetobacter spp.) against certain antibiotics, including those used only in cases where there are no other therapeutic options.

Objective: The aim of the study was to assess the long-term impact of laparoscopic sleeve gastrectomy (LSG) on lipid profile, uric acid level and metabolic syndrome. Materials and methods: A prospective study was performed between 2009-2014, evaluating long-term percentage of excesso body mass index loss (%EBMIL), lipid profile, uric acid level and metabolic syndrome. Results:Overall sixty subjects were followed-up. %EBMIL increased significantly, reaching a maximum (86,9 +/- 6,3%) at 5 years post-LSG. Therapeutic success rate (%EBMIL >= 60%) was 80% at 5 years. The triglyceride level decreased significantly (148 +/- 72.1 mg/dL baseline vs 130.7 +/- 57.5 mg/dL at 1 month vs 110.7 +/- 42.6 mg/dL at 3 months vs 92.5 +/- 35.2 mg/dL at 1 year vs 84.2 +/- 32.3 mg/dL at 5 years; p < 0.05 for all). HDL-cholesterol increased and uric acid decreased significantly in the first year postoperatively, remaining stable afterwards (46.9 +/- 12.3 mg/dL baseline vs 47.4 +/- 10 mg/dL at 1 month vs 49.8 9.3 mg/dL at 3 months vs 55.4 +/- 10.2 mg/dL at 1 year; p < 0.05 for all for HDL-cholesterol and 6.4 +/- 2 mg/dL baseline vs 6 +/- 13 mg/dL at 1 month vs 5.2 +/- 1.3 mg/dL at 3 months vs 4.8 +/- 1 mg/dL at 1 year; p < 0.05 for all for uric acid).The prevalence of metabolic syndrome decreased from 66.7% baseline to 8.3% at 5 years postoperatively (p < 0.01). Conclusions: LSG was effective in terms of %EBMIL and metabolic traits improvement for Romanian patients.

Background: Rhizobium (Agrobacterium) species are plant aerobic bacteria, which in some cases can produce endophthalmitis in humans after corneal trauma. Case presentation: A 42-year-old female patient presented in the Emergency Department of the Emergency County Hospital of Craiova, Romania, reporting pain, epiphora, and blurry vision in her right eye for about five days. This initial infectious keratitis episode was successfully resolved, but after 20 days she presented again after trauma with a leaf with corneal abscess. In the conjunctival secretion, R. radiobacter was identified. Despite antibiotherapy, the patient’s state did not improve, and ultimately the eye was eviscerated. Methods: A search was performed in the ProQuest, PubMed, and ScienceDirect databases for the terms Agrobacterium, Rhizobium, radiobacter, and eye. We eliminated non-human studies, editorials and commentaries, and non-relevant content, and excluded the duplicates. Results: In total, 138 studies were initially obtained, and then we selected 26 studies for retrieval. After the selection process, we ended up including 17 studies in our analysis. Most studies reported R. radiobacter endophthalmitis after ocular surgical procedures or outdoor activities that involve exposure to soil. Conclusion: R. radiobacter is a rare cause of endophthalmitis after eye trauma that generally responds well to usual antibiotherapy, but occasionally can evolve to severe, leading to the loss of the eye.
