Abstract Introduction: Infections are the most feared complication of transrectal prostate biopsies, along with growing concerns of antibiotic resistance. Our institution transitioned to a transperineal approach without use of perioperative antibiotics or bowel preparations. We aimed to compare the safety outcomes associated with transperineal and transrectal prostate biopsy techniques. Materials and Methods: A retrospective analysis of patients who underwent transrectal and transperineal prostate biopsies at our institution from 2019–2022 was performed. Results: We identified 319 patients—174 transrectal and 145 transperineal. 8 patients who had transperineal biopsy (5.5%) received peri-operative antibiotics, compared to 100% with transrectal biopsy. 35.86%… More >

Abstract Background: immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic urothelial carcinoma (mUC), significantly improving survival outcomes. However, a subset of patients do not respond to ICIs, prompting research into potential predictive factors. Commonly prescribed medications such as corticosteroids, proton-pump inhibitors (PPIs), antibiotics (Abs), antihypertensives, and analgesics may influence ICI effectiveness. Methods: we conducted a literature search on PubMed to investigate the impact of concomitant medications on the outcomes of patients with mUC, treated with ICIs. We selected the most relevant studies and performed a narrative review. Results: corticosteroids, PPIs and Abs have been associated More >

Abstract Introduction: We evaluate the rate of developing ciprofloxacin resistance in patients undergoing repeat prostate biopsies (PBx), associated risk factors, and impact on complications.
Materials and methods: We retrospectively evaluated pre-procedural rectal culture (RCx) data in men undergoing PBx from 1/1/2016 to 1/15/2021. Univariate and multivariate logistic regression were utilized to identify risk factors associated with development of antibiotic resistance. Complication rates were compared between ciprofloxacin-sensitive and ciprofloxacin resistant patients.
Results: A total of 743 men underwent initial RCx. Initial RCx detected ciprofloxacin resistance in 22% of patients. A history of diabetes (p = 0.01), > 2 prior prostate… More >

Abstract Introduction: There is an ongoing debate as to the appropriate regimen of antibiotic prophylaxis with transperineal (TP) biopsy. The objective of this study was to report the rate of infection following TP biopsy at a high-volume institution and assess the impact of single dose antibiotics at the time of biopsy versus outpatient antibiotics in preventing postprocedural infections.
Materials and methods: Records of men undergoing TP prostate biopsy from 2012 to 2022 were reviewed. Patients were divided into two groups, those who received single dose intravenous (IV) antibiotics at the time of biopsy (n = 440) and those… More >

Abstract The androgen receptor (AR) is a critical target in all the clinical stages of prostate cancer. To identify a new AR inhibitor, we constructed a new screening system using the androgen-dependent growth of prostate cancer cell lines as a screening indicator. We screened 50,000 culture broths of microorganisms using this screening system and found that the fermentation broth produced by a fungus inhibited androgen-dependent growth of human prostate cancer LNCaP cells without cytotoxicity. Purification of this culture medium was performed, and this resulted in deoxynortryptoquivaline (DNT) being identified as a novel inhibitor of AR function. More > Graphic Abstract

Abstract The effect of beta-lactam antibiotics on shoot induction and plantlet regeneration from cotyledonary nodes was tested using two peanut cultivars. The culture media contained 4 mg/L 6-benzylaminopurine (BAP) as the main growth regulator. Various concentrations (100–600 mg/L) of cefotaxime, carbenicillin, and timentin were applied in the culture media. In all the tested media, there were no significant differences in the shoot induction as compared to the control. However, little phytotoxic effect was observed at higher concentrations of these antibiotics in the shoot elongation media. Under shoot elongation medium, shoots turned brownish and partly died at… More >

Abstract Profound inspection of the life forms on the earth teaches how to be the complexity of interrelationships among the various systems. Because of the emergence of novel viruses all the time and the inadequate of vaccines and antivirals, viral contagions are amongst the most causative diseases affecting people worldwide. Fungi exemplify a massive source of bioactive molecules as, many fungal secondary metabolities like Oxoglyantrypine, Carneic acid F, Scedapin C, Asteltoxin E, Phomanolide, Norquinadoline A and Quinadoline B have antiviral activity. This review deals with how secondary metabolites of fungi can help in the war against More >

Abstract The extraction of bioactive compounds has become one of the most interesting areas of modern chemistry. For therapeutic reasons, it´s important to obtain antimicrobial agents from natural origin. The objective of the present study was to determine the inhibitory effect of ethanolic extract of basil (Ocimum basilicum L. var. Red Rubin) subjected to different concentrations of potassium (K⁺) on the activity of three bacterial strains that are pathogens in humans. Susceptibility was evaluated by inhibition surface and these results were compared to two antibiotics: Gentamicin (GE) and Ciprofloxacin (CPF) for their efficacy against each bacterial strain.

Abstract Introduction: We sought to explore whether patients discharged without antibiotics after artificial urinary sphincter (AUS) insertion were more likely to require device explantation for infection or erosion compared to patients discharged with antibiotics at our institution and compared to patients in other large, contemporary series.
Materials and methods: AUS insertions performed at our institution between 2013 and 2017 were retrospectively reviewed to determine demographics, comorbidities, and perioperative and medium-term outcomes. Patients were grouped based on 1) known risk factors for infectious complications or erosion and 2) postoperative antibiotic prescription status. Patients were placed in Group 1 if… More >
