Contemporary National Trend in Surgical Management of Hemodynamically Unstable Pediatric Blunt Splenic Injury.

Background: Evaluation of response to blood transfusion after blunt splenic injury (BSI) may prevent the need for splenectomy. The aim of this study was to evaluate factors associated with splenectomy in pediatric patients with isolated BSI who presented with hemodynamic instability with a focus on timing of transfusion.

Methods: The 2021 Trauma Quality Improvement Project database was queried for children ≤18 years with BSI who arrived with a shock index>1.

Patient outcomes by baseline pathogen resistance phenotype and genotype in CERTAIN-1, a Phase 3 study of cefepime-taniborbactam versus meropenem in adults with complicated urinary tract infection.

Unlabelled: CERTAIN-1 was a Phase 3, double-blind, randomized, parallel group study of the efficacy and safety of cefepime-taniborbactam versus meropenem in the treatment of adults with complicated urinary tract infection (cUTI), including acute pyelonephritis. We determined susceptibility of Enterobacterales and baseline pathogens to cefepime-taniborbactam and comparators and characterized β-lactam resistance mechanisms. Microbiologic response and clinical response were assessed in patient subsets defined by baseline pathogens that were of cefepime-, multidrug-, or carbapenem-resistant phenotype or that carried β-lactamase genes.

The impact of ovarian stimulation on the human endometrial microenvironment.

Study Question: How does ovarian stimulation (OS), which is used to mature multiple oocytes for ART procedures, impact the principal cellular compartments and transcriptome of the human endometrium in the periovulatory and mid-secretory phases?

Summary Answer: During the mid-secretory window of implantation, OS alters the abundance of endometrial immune cells, whereas during the periovulatory period, OS substantially changes the endometrial transcriptome and impacts both endometrial glandular and immune cells.

What Is Known Already: Pregnancies conceived in an OS cycle are at risk of complications reflective of abnormal placentation and placental function. OS can alter endometrial gene expression and immune cell populations.

Cefepime-Taniborbactam in Complicated Urinary Tract Infection.

Background: Carbapenem-resistant Enterobacterales species and multidrug-resistant are global health threats. Cefepime-taniborbactam is an investigational β-lactam and β-lactamase inhibitor combination with activity against Enterobacterales species and expressing serine and metallo-β-lactamases.

Methods: In this phase 3, double-blind, randomized trial, we assigned hospitalized adults with complicated urinary tract infection (UTI), including acute pyelonephritis, in a 2:1 ratio to receive intravenous cefepime-taniborbactam (2.
