Background: To compare the epidemiologic, microbiologic and imaging characteristics of urinary tract infections (UTI) in children <2 years of age with and without anatomic urinary tract abnormalities (AA).
Methods: All children hospitalized with UTI during 1.1.2005-31.12.2018 were included. The study group (patients with AA) included 76 patients. The control group (99 patients) included patients without AA.
Results: 1163 children were hospitalized. Age at diagnosis was younger in the study group vs. controls (5.2 ± 6.0 vs. 7.9 ± 7.5 months, P = 0.038). Uropathogens distribution was different (P = 0.007), with lower Escherichia coli (Ec) and Proteus mirabilis (Pm) percentages in the study group and higher percentages of Enterococcus spp. (Ent) in controls. In the study group, Ec nonsusceptibility rates to ampicillin, amoxicillin/clavulanic acid, cefazolin, cefuroxime, TMP/SMX and ceftriaxone were 58%, 40%, 14%, 14%, 12% and 10%, respectively, with no differences vs. controls. Ultrasound (US) was performed in 69/76 (98%) patients with AA (84.1%, abnormal); bilateral (39.7%) and unilateral (32.7%) ureteral dilatation were the most frequent findings. Voiding cystourethrography was performed in 46 patients (pathologic in 35, 76%); 31 (81.6%) patients had vesicoureteral reflux (VUR) (bilateral in 11, 35.5%; grade 4/5 in 7 patients). Uropathogens distribution in VUR patients differed between study and control groups, with lower Ec and Pm in the first group and higher Pseudomonas aeruginosa and Ent percentages in the control group.
Conclusion: Age at diagnosis was lower and pathogen distribution was different in patients with AA. Antibiotic susceptibility patterns of the main uropathogens were similar between patients with or without AA.

Clinical impact of healthcare-associated infections in Brazilian ICUs: a multicenter prospective cohort.

HCor Research Institute, Hospital do Coração, Rua Desembargador Eliseu Guilherme 200, 8th Floor, São Paulo, SP, 04004-030, Brazil.
Background: Limited data is available to evaluate the burden of device associated healthcare infections (HAI) [central line associated bloodstream infection (CLABSI), catheter associated urinary tract infection (CAUTI), and ventilator associated pneumonia (VAP)] in low and-middle-income countries. Our aim is to investigate the population attributable mortality fraction and the absolute mortality difference of HAI in a broad population of critically ill patients from Brazil.
Methods: Multicenter cohort study from September 2019 to December 2023 with prospective individual patient data collection.
Flow prediction in sound-based uroflowmetry.

Sound-based uroflowmetry (SU) offers a non-invasive alternative to traditional uroflowmetry (UF) for evaluating lower urinary tract dysfunctions, enabling home-based testing and reducing the need for clinic visits. This study compares SU and UF in estimating urine flow rate and voided volume in 50 male volunteers (aged 18-60), with UF results from a Minze uroflowmeter as the reference standard. Audio signals recorded during voiding were segmented and machine learning algorithms (gradient boosting, random forest, and support vector machine) estimated flow parameters from three devices: Ultramic384k, Mi A1 smartphone, and Oppo smartwatch.

Introduction: Primary bladder neck obstruction (PBNO) is a rare but significant cause of BOO and LUTS in females, with unclear etiology involving theories of fibrotic narrowing, tissue hyperplasia, or muscle abnormalities. Due to nonspecific symptoms, PBNO diagnosis remains challenging, and optimal surgical treatment needs to be better defined.
Case Presentation: We report two cases of females in their 50s with recurrent urinary retention managed by indwelling catheters.

Monitoring subcellular organelle dynamics in real time and precisely assessing membrane heterogeneity in living cells are very important for studying fundamental biological mechanisms and gaining a comprehensive understanding of cellular processes. However, there remains a shortage of effective tools for these purposes. Herein, we propose a strategy to develop the exchangeable water-sensing probeAPBD for time-lapse imaging of dynamics in cellular membrane-bound organelle morphology with structured illumination microscopy at the nanoscale.

Studies in literature discussed the drawbacks of the ureteral access sheath use in flexible ureteroscopy and in the same time mentioned the benefits of ureteral access sheath in decreasing the incidence of urosepsis and better stone free rate. In the current study we aim to compare between percutaneous nephrostomy tube (PCN) insertion before flexible ureteroscopy and conventional ureteral access sheath (UAS) flexible ureteroscopy in terms of safety, efficacy and perioperative outcomes. In all, 100 Patients aged 20 to 67 years with upper ureteric stones and mild hydronephrosis or renal pelvic stones less than 20 mm with mild hydronephrosis were randomized into 2 groups; patients undergoing PCN insertion before flexible ureteroscopy, and patients undergoing the conventional UAS flexible ureteroscopy.
