Abstract
INTRODUCTION Despite increasing resistance of enterobacteria against fluoroquinolones (FLU), they are still widely used during transrectal prostate biopsy (TRPB). This study was designed to analyse infectious complications and risk factors between FLU, cephalosporines (CEPH) and selective other antibiotics (O-AB) used during TRPB. METHODS 664 patients were included retrospectively (152 FLU, 452 CEPH and 60 O-AB). Infectious complications were defined as fever >38.0°C, the in-house definition of complicated urinary tract infection (cUTI) (if all applied: fever >38.0°C, leucocytosis >11.000/µL and positive urine dipstick) or postinterventional bacteriuria. Hospitalisation rate, duration and comorbidities were also assessed. χ2 and Fisher's exact test were used for group comparison. Multivariate regression analysis assessed the association of comorbidities with infectious complications. RESULTS FLU and CEPH were indifferent regarding infectious complications, however in the O-AB group significantly more common compared to FLU and CEPH (11.6, 13.3, 25%, p < 0.05). Duration of hospital stay in CEPH was significantly shorter compared to FLU and O-AB (4.1 vs. 6.3 vs. 8.2 days, p < 0.05). Arterial hypertension showed increased association with fever (OR 6.002 (1.178; 30.597) p = 0.031) and cUTI (OR 6.006 (1.207; 29.891) p = 0.029). CONCLUSION Infectious complications were low and indifferent between FLU and CEPH but significantly more frequent in O-AB. Arterial hypertension was significantly associated with postinterventional fever and cUTI.

Abstract
The aim of this study was to investigate multi-drug-resistant (MDR) Escherichia coli in urine of adult male patients with enlarged prostate. Three hundred and sixty-eight samples of urine and blood were collected. Escherichia coli was isolated, purified, and identified and prostate-specific antigen (PSA) was determined. Multi-drug resistance test and specific drug resistance genes were assessed. Prevalence of Escherichia coli was high (38.5%) in patients with PSA of 60-79 ng ml-1 and 60% were MDR. The isolates showed highest resistance to tetracycline (53.3.0%) and least to cephalosporins (5%). They had intL and gyrA genes, which are integron, and quinolone resistance genes and sul1 and sul2 which are sulphonamide resistance-associated genes. Levofloxacin, ertapenem, and Augmentin (100% susceptibilities) were considered choice drugs for treatment of Escherichia coli infection in patients with elevated PSA.

Novel Antibacterial Agents SAAP-148 and Halicin Combat Gram-Negative Bacteria Colonizing Catheters. Antibiotics (Basel) 2023; 12:1743. [PMID: 38136778 PMCID: PMC10741160 DOI: 10.3390/antibiotics12121743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 12/07/2023] [Accepted: 12/12/2023] [Indexed: 12/24/2023] Open
Abstract
The antibiotic management of catheter-related infections (CRIs) often fails owing to the emergence of antimicrobial-resistant strains and/or biofilm/persister apparitions. Thus, we investigated the efficacy of two novel antimicrobial agents, i.e., the synthetic peptide SAAP-148 and the novel antibiotic halicin, against Gram-negative bacteria (GNB) colonizing catheters. The antibacterial, anti-biofilm, and anti-persister activities of both agents were evaluated against Acinetobacter baumannii, Escherichia coli, and Klebsiella pneumoniae strains. The enrolled strains were isolated from catheters and selected based on their resistance to at least three antibiotic classes and biofilm formation potential. Furthermore, the hemolysis and endotoxin neutralization abilities of these agents were explored. The bactericidal activity of both agents was reduced in urine and plasma as compared to buffered saline. In a dose-dependent manner, SAAP-148 and halicin reduced bacterial counts in 24 h preformed biofilms on silicone elastomer discs and eliminated persisters originating from antibiotic-exposed mature 7-day biofilms, with halicin being less effective than SAAP-148. Importantly, SAAP-148 and halicin acted synergistically on E. coli and K. pneumoniae biofilms but not on A. baumannii biofilms. The peptide, but not halicin, decreased the production of IL-12p40 upon exposure to UV-killed bacteria. This preliminary study showed that SAAP-148 and halicin alone/in combination are promising candidates to fight GNB colonizing catheters.

Infect Drug Resist 2023; 16:105-113. [PMID: 36636373 PMCID: PMC9831077 DOI: 10.2147/idr.s390837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Accepted: 12/22/2022] [Indexed: 01/06/2023] Open
Abstract
Study Design Retrospective cohort study. Objective This study aimed to investigate the characteristics of microflora in patients with deep spinal surgical site infection (SSI) after prophylactic use of vancomycin powder (VP). Methods A retrospective analysis was performed on patients after spinal surgery. Patients were grouped according to whether VP use and only patients with deep SSI were included in this study. General information of the patients, the dose of vancomycin, bacterial culture results, drug sensitivity test results, and SSI treatment methods were recorded. The differences of microflora between the two groups were analyzed, and the sensitivity of bacteria in the +VP group to antibiotics was analyzed. Results The infection rate in the +VP group was 4.9% (56/1124) vs 6.3% (93/1476) in the No-VP group (P < 0.05). The proportion of Gram-positive bacteria (GPB) in the +VP SSIs was 55.4% vs.74.1% in the No-VP group (P < 0.05). The percentage of Gram-negative bacteria (GNB) in the +VP SSIs was 46.4% vs.30.1% in the No-VP group (P < 0.05). More dose of VP cannot decrease the SSI, but the proportion of GNB in VP >1g SSIs was higher (59.0% vs 32.4%, P < 0.05). In the +VP SSIs, all of the GNB cultured were sensitive to meropenem, and linezolid covered most of the GPB cultured. Conclusion Local use of vancomycin powder can reduce the incidence of SSI, but this may lead to changes in the bacterial flora. Once the SSI occurs, the case of GNB infection may be increased. The more dose of VP cannot decrease SSI but may increase the rate of GNB in the +VP SSIs. Once infections still occur after VP use, antibiotics covering GNB may be added. These findings may help guide choice of empiric antibiotics while awaiting culture data.

Abstract
Although the incidence and mortality of prostate cancer have gradually begun to decline in the past few years, it is still one of the leading causes of death from malignant tumors in the world. The occurrence and development of prostate cancer are affected by race, family history, microenvironment, and other factors. In recent decades, more and more studies have confirmed that prostate microflora in the tumor microenvironment may play an important role in the occurrence, development, and prognosis of prostate cancer. Microorganisms or their metabolites may affect the occurrence and metastasis of cancer cells or regulate anti-cancer immune surveillance. In addition, the use of tumor microenvironment bacteria in interventional targeting therapy of tumors also shows a unique advantage. In this review, we introduce the pathway of microbiota into prostate cancer, focusing on the mechanism of microorganisms in tumorigenesis and development, as well as the prospect and significance of microorganisms as tumor biomarkers and tumor prevention and treatment.

Abstract
Purpose Gram-negative rods of the genus Serratia play an increasing role as etiological agents of healthcare-associated infections (HAI) in humans. These bacteria are characterized by natural and acquired resistance to several groups of antibacterial agents. The aim of the study was to characterize class 1, 2 and 3 integrons in the clinical isolates of Serratia spp. in Poland. Methods The study comprised 112 clinical strains of Serratia, isolated from patients hospitalized in Poland in 2010-2012. Identification of strains was confirmed using MALDI-TOF MS (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry) system. Detection of class 1, 2 and 3 integrase DNA sequence was performed by multiplex-PCR. Amplicons obtained in the PCR reactions were purified and then sequenced bidirectionally. Results Among the analyzed strains, Serratia marcescens was a predominant species (103/112, 92.0%). All three classes of integrase DNA sequence were detected in the analyzed strains of Serratia spp. DNA sequence of class 3 integron, besides integrase gene, revealed three gene cassettes (dfrB3, bla GES-7,bla OXA/aac(6')-Ib-cr). BLAST analysis of DNA sequence revealed that class 3 integron was carried on 9448 bp plasmid which was named pPCMI3 - whole sequence of its DNA was submitted to GenBank NCBI (National Center for Biotechnology Information) - NCBI MH569711. Conclusion In this study, we identified a new plasmid pPCMI3 harboring class 3 integron. This is the first report of a gene oxa/aac(6')-Ib-cr coding for a novel fusion protein, which consists of OXA β-lactamase and acetyltransferase aac(6')-Ib-cr. In the analyzed strains, class 1 and 2 integrons were also detected. Among the strains with class 1 integron, nine contained cassette array 5'CS-aadA2-ORF-dfrA12-3'CS, and two - cassette array 5'CS-aacC1-ORF-ORF-aadA1-3'CS, which were not previously reported in Serratia spp.

Abstract
Objective The aim of this study was to investigate the effects of acupuncture on urinary retention and provide treatment suggestions. Methods A total of 113 hospitalized patients with urinary retention were included in this study. The GV20, CV6, CV4, CV3, ST28, SP6, and SP9 points were selected as the main acupoints. Acupuncture therapy was conducted for 30 minutes per session. The total number of treatment sessions was determined by the symptoms and the length of hospital stay. Bladder postvoid residual urine volume (PVR) was measured pretreatment and posttreatment by ultrasonic. Efficacy defined as spontaneous urination and a residual urine volume <50 mL was measured. Results The median number of acupuncture treatment sessions was 3 (range, 1-12 times). Acupuncture treatment significantly reduced the PVR (545.1 ± 23.9 mL vs 67.4 ± 10.7 mL; p < 0.001). Among the 113 patients, 99 (87.6%) patients were cured and 8 (7.1%) patients were improved of their urinary retention. The remaining 6 (5.3%) patients' urinary retention did not improve. The effective rate was 94.7%. There was significant difference in the efficacy rate between patients with one urinary catheterization and with two or more. Acupuncture treatment was not associated with side effects. Conclusion Acupuncture is an effective and safe treatment option for urinary retention. Early application of acupuncture treatment should be considered in clinic, and repeated urinary catheter insertion and removal should be avoided. Our study suggests that a randomized controlled study with a large sample size to verify the efficacy of acupuncture for the treatment of urinary retention is warranted.
