Article Abstract
Objective: Our objective was to characterize the incidence, associated clinical factors, timing of infection, microbiology, and incidence of concordant blood culture of urinary tract infections (UTIs) in very low birth weight (VLBW <1,500g) infants.
Study Design: Multicenter observational cohort study of VLBW infants with gestational age (GA) ≤32 weeks, still hospitalized on postnatal day 7, and discharged 2010 to 2018 from Pediatrix Medical Group neonatal intensive care units. Demographic and clinical characteristics of infants with and without UTI were compared. Multivariable logistic regression evaluated adjusted odds of UTI diagnosis.
Results: Of 86,492 included infants, 5,988 (7%) had a UTI. The most common pathogen was . (20%), followed by (19%) and . (18%). . (6%) was the most common nonbacterial pathogen. Concordant-positive blood culture was present in 8% of infants with UTI diagnoses. UTI was associated with lower GA, male sex, vaginal delivery, prenatal steroid exposure, and longer duration of hospitalization.
Conclusion: UTI is a common cause of infection in VLBW infants, especially among the smallest, most premature, male infants, and those with a longer duration of hospitalization. Neonatal clinicians should consider obtaining urine culture in the setting of late-onset sepsis evaluations in VLBW infants.
Key Points: · UTI is a common cause of LOS in VLBW infants.. · The most common pathogens are Enterococcus spp. and E. coli.. · UTI risk varies among different VLBW infant populations.. · Next steps should include evaluation of preventative measures..

Effect of Monopolar Versus Bipolar Transurethral Resection of The Prostate on Erectile Function: A Randomized Controlled Trial with Phosphodiesterase-5 Inhibitors Users Subgroup Analysis.

Purpose: Men with lower urinary tract symptoms (LUTS) from benign prostatic hyperplasia (BPH) often experience erectile dysfunction (ED). While transurethral resection of the prostate (TURP) can improve ED, new-onset ED remains a concern. This study compares monopolar (M-TURP) and bipolar (B-TURP) techniques, with a subgroup analysis based on phosphodiesterase-5 inhibitor (PDE5i) use.

Affiliated Hospital of Nantong University, Emergency Department, Nantong, 226000, Jiangsu, China.
Purpose: Urosepsis, a condition caused by a urinary tract infection spreading to the bloodstream, has a complex epigenetic behavior in its cellular and molecular pathophysiology. The objective of this study was to identify relevant genes and signaling pathways in adult urosepsis through a bioinformatic analysis of differentially expressed genes (DEGs).
Materials And Methods: In this in-silico study, the GSE69528 dataset, containing 138 total RNA blood samples from patients with sepsis and uninfected controls, was obtained from the Gene Expression Omnibus (GEO) database.

Background: Intravenous lipid emulsions are a key component of parenteral nutrition, and their fatty acid compositions may influence immune responses and clinical outcomes.
Methods: This retrospective cohort study conducted from January 2020 to December 2022 compared clinical outcomes of hospitalized non-critical care patients receiving parenteral nutrition with either mixed oil or soybean oil lipid emulsions for at least 48 h. The primary outcome was a composite of the presence of pneumonia, urinary tract infection, or an intra-abdominal collection diagnosed within 14 days of initiating parenteral nutrition.

Background: Ovarian mature teratomas (OMTs) are the most common benign ovarian tumors in pediatric patients. Management in adolescents can be performed by pediatric (PSs) or gynecologic surgeons (GSs). The aim of this study was to assess the differences in OMT management and the repercussions according to the risk of secondary events.

Renal ischemic disease represents a severe clinical pathological condition commonly observed in acute kidney injury (AKI), renal transplantation, and kidney surgery. It leads to renal tubular epithelial cell damage, inflammatory responses, and cell death, potentially progressing to chronic kidney disease (CKD) or even renal failure, significantly impairing patients' quality of life and survival rates. Current therapeutic strategies for renal ischemia-reperfusion injury (IRI) include pharmacological interventions, cell therapy, and gene therapy, yet their efficacy remains limited and may be accompanied by adverse effects.
