To address the limitations in existing urinary stone recurrence (USR) models, including failure to account for changes in 24-hour urine (24U) parameters over time and ignoring multiplicity of stone recurrences, we presented a novel statistical method to jointly model temporal trends in 24U parameters and multiple recurrent stone events. The MSTONE database spanning May 2001 to April 2015 was analyzed. A joint recurrent model was employed, combining a linear mixed-effects model for longitudinal 24U parameters and a recurrent event model with a dynamic first-order Autoregressive (AR(1)) structure.

Venetoclax is a BH3 mimetic that was recently approved for the treatment of acute myeloid leukemia (AML) treatment. However, the effect of venetoclax on AML remains limited, and a novel strategy is required. Here, we demonstrate for the first time that the cytotoxic effect of venetoclax drastically increased when by combined with the naturally occurring flavonoid quercetin.

Background: Laparoscopic liver resection (LLR) has been associated with improved patient recovery as well as reduced postoperative adhesions compared to open LR (OLR) and could therefore facilitate redo liver surgery. LLR prior to liver transplantation (LT) is increasingly performed, LT being saved for HCC recurrence. LT is still performed by open surgery due to vascular reconstructions and underlying liver chronic disease.

In early 2020, as the SARS-Cov-2 (COVID-19) pandemic progressed, many institutions limited nonurgent surgical care. This coincided with a decade-long trend of increasing percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS) and decreasing shock wave lithotripsy (SWL) for surgical management of urolithiasis. Herein, we evaluate temporal stone surgery rates and surgeon volumes in the Medicare population and suggest how COVID-19 contributed to them.

Introduction Central venous access devices (CVADs) are indispensable in the management of pediatric cancer patients, offering vital access to treatment. Yet, complications related to CVADs, such as infections, thrombosis, and dislocations, pose significant risks, potentially leading to prolonged hospitalization, intensive care unit admission, or even mortality. To address these challenges, our hospital established a pediatric CVAD surveillance and rounding team to improve the management and care of pediatric patients with CVADs.

Article Synopsis
  • - The study aimed to evaluate how kidney stone disease (KSD) and its treatments affect the health-related quality of life (HRQOL) in high-risk patients with conditions like hyperparathyroidism and medullary sponge kidney.
  • - Researchers used a questionnaire on 3,301 patients over six years, revealing that high-risk patients (120 of 1,499 active KSD patients) reported significantly lower HRQOL scores than controls.
  • - Specific conditions such as medullary sponge kidney disease and renal tubular acidosis were linked to worse HRQOL, while alkali therapy was associated with improved HRQOL, highlighting the need for earlier identification and treatment of high-risk patients.

Background: Neonatal serum creatinine (n-sCr) concentrations during the first few days of life have been reported to correlate with the maternal serum Cr (m-sCr) concentrations. We aimed to derive a regression equation to describe the relationship between n-sCr within 24 h of birth in preterm neonates and m-sCr before delivery, and to perform multiple regression analysis to identify factors related to n-sCr and the difference between n-sCr and m-sCr.

Methods: We recruited preterm neonates who were treated at the University of the Ryukyus Hospital between March 2012 and October 2022.
