Article Abstract
Purpose: To compare procedure characteristics and outcomes when TIPS is performed under intracardiac echocardiography guidance (iTIPS) compared to conventional fluoroscopic guidance (cTIPS).
Materials And Methods: A retrospective propensity-matched study of 30 iTIPS and 30 cTIPS procedures from January 2014 to March 2017 at a single US high volume academic medical center was performed. iTIPS and cTIPS cases were propensity score matched using predictive variables: age, race, gender, etiology of liver disease, indication for TIPS, MELD score, and portal vein patency. Procedure characteristics and post- procedure outcomes were compared between propensity-matched groups including: total procedure time, technical success, radiation dose, contrast volume, complication rate, 30- day mortality, and revision rate within 3 months.
Results: Radiation dose (875.3 vs 457.4 mGY, p = 0.039) and contrast volume (141 vs 103 mL, p = 0.005) were significantly decreased in the iTIPS versus the cTIPS group. There was no significant difference in procedure time (81.5 cTIPS vs 84 min iTIPS) or rate of TIPS revisions within 3 months. Average operator experience in the iTIPs group was 4.2 years and cTIPS group 11.0 years (p = 0.0004). All procedures were technically successful with no mortalities within 30 days.
Conclusion: iTIPS resulted in significantly reduced radiation dose and contrast volume. However, there was no difference in total procedure time or overall outcomes despite greater operator experience in the cTIPS group.

Background: Current management of pediatric cutaneous abscesses involves either spontaneous healing by secondary intention or suturing through tertiary intention, which are often lengthy processes that cause discomfort and distress among children. As it is noninvasive and simple, a novel zipper device is widely used for the primary wound closure of surgical incisions.
Objective: To describe the effectiveness of novel zipper device use for pediatric cutaneous abscess wound closure in an outpatient context.

Background: Diabetic foot ulcers (DFUs) are a major clinical challenge, particularly among patients with refractory ulcers, that often lead to severe complications such as infection, amputation, and high mortality. Innovations supported by strong clinical evidence have the potential to improve healing outcomes, enhance quality of life, and reduce the economic burden on individuals and health care systems.
Objective: To describe the design of the concurrent optical and magnetic stimulation (COMS) therapy Investigational Device Exemption (IDE) study for refractory DFUs (MAVERICKS) trial.

Background: As populations age, informal caregivers play an increasingly vital role in long-term care, with 80% of care provided by family members in Europe. However, many individuals do not immediately recognize themselves as caregivers, especially in the early stages. This lack of awareness can increase physical and emotional stress and delay access to support services.

Patulin (PAT), a mycotoxin produced primarily by Penicillium expansum, poses significant health risks and frequently contaminates apples and apple-derived products, often exceeding permissible safety limits. This study investigated the potential of orotate phosphoribosyl transferase (URA5) to degrade PAT in apple juice under controlled conditions. PAT degradation was assessed at initial concentrations of 100 µg/L and 250 µg/L, with enzymatic treatment using 0.
