Article Abstract
Urine collection can be challenging in studies involving small rodents like mice, as the actual methods of collection are anxiogenic and constrain animal welfare while having high variability in the volume of urine collected. To improve the current methods and eventually reduce the impact on the well-being of mice, we developed an innovative 3D-printed urine collection device (UCD). This two-compartment UCD is shaped to fit in classical husbandry cages and allows urine collection by spontaneous urination from two mice housed in their own cage without cross-contamination while enabling potential social interactions. We used our UCD to study the evolution of urinary parameters related to renal functions in a model of antibody-mediated chronic kidney disease. Overall, we report here a time-saving and affordable method for urine collection providing a large amount of uncontaminated urine and which we believe may improve animal welfare in comparison with other methods.

24-h urine test application in patients with kidney stone disease: a population-based study in a primary care setting.
J Nephrol

Italian Society of General Medicine (SIMG), COMEGEN Primary Care Physicians Cooperative, Naples, Italy.
Background: Kidney stone formation is driven by an imbalance between lithogenic substances and crystallization inhibitors. Current guidelines recommend a 24-h urine collection in patients with kidney stone disease to assess the risk of stone formation and monitor therapy compliance. However, real-world data on adherence to these guidelines remain limited and outdated.

Background: Levetiracetam, a first-line antiseizure medication, is primarily eliminated through the kidneys, with approximately 66% renal elimination. Consequently, its pharmacokinetics are significantly influenced by kidney function. Augmented renal clearance (ARC), a condition characterized by renal hyperfiltration, is frequently observed in critical care settings and can profoundly impact the disposition of renally eliminated drugs such as levetiracetam.

Background: Untargeted metabolomic analysis provides novel insights into the relationship between sodium intake and cardiometabolic risk. This study examined cross-sectional associations between estimated sodium intake and plasma metabolite profiles in a large Swedish cohort.
Methods: This cross-sectional analysis was conducted in the in the SCAPIS cohort (mean age 50-64 years, n = 8,957).
Diagnostic insights from the 2024 West Nile Virus outbreak in Israel: Emphasizing the utility of molecular testing over serology.
J Clin Virol

Background: In 2024, Israel experienced its largest West Nile Virus (WNV) outbreak, reporting 934 cases. Diagnosis primarily relies on serological testing for IgM antibodies; however, cross-reactivity with other flaviviruses and prolonged IgM persistence complicate interpretation. Molecular testing is less utilized due to concerns about the short duration of viremia and potential false negatives.

A fully implantable sensorized organ to replace the natural urinary bladder holds considerable promise for patients undergoing radical cystectomy. Clinical options to restore continence include urine redirection to wearable bags or reconstruction of neobladders from autologous tissues, often with limited capacity. However, none of these approaches can restore patient's ability to perceive bladder fullness, making voiding self-management complex and burdensome.
