Ureteral Tissue Temperature During Ureteroscopy With Ho:YAG Laser Activation in an In Vivo Porcine Model.

Objective: To measure temperature of the outer ureteral wall and calculate thermal dose with different irrigation and laser power settings during ureteroscopy in a porcine in vivo model.

Methods: The ureters of two porcine subjects were exposed through laparotomy incisions. A length of PFA tubing, with equally spaced windows, was inserted into the ureter through a ureterotomy.

Characterizing stone ablation with the thulium fiber laser: a single-pulse comparison of different pulse durations.

Stone ablation using the thulium fiber laser (TFL) at different pulse duration/peak power or laser fiber-to-stone distances requires further research to understand effective and safe settings. In this study we characterized the vapor bubble anatomy and stone crater morphology at various settings and standoff distances. Optical profiles of 1 J short pulse (SP), 1 J long pulse (LP), 3 J SP, and 2.

Cost Savings and Improved Clinical Outcomes From a Mobile Health Cardiovascular Disease Self-Management Program.

Objectives: This study evaluated the impact of a mobile health (mHealth) cardiovascular disease (CVD) self-management program on medical spending, healthcare utilization, and clinical outcomes.

Methods: We conducted a retrospective cohort, pre-post observational analysis of medical claims data from February 2018 to September 2023. Participants enrolled in the mHealth CVD self-management program were compared with matched nonparticipants to assess changes in medical spending and utilization, using a difference-in-differences (DiD) approach.

Three reference genomes for freshwater diatom ecology and evolution.

Diatoms are an important component of marine and freshwater ecosystems. Although the majority of described diatom species live in freshwater systems, genome sequencing efforts have focused primarily on marine species. Genomic resources for freshwater species have the potential to improve our understanding of diatom ecology and evolution, particularly in the context of major environmental shifts.
