Article Abstract
Purpose: This study aimed to evaluate the technical and clinical success rates of transcatheter arterial embolization (TAE) for subcapsular hematoma of the liver.
Methods: Between January 2010 and March 2022, 34 patients underwent TAE for subcapsular hematomas of the liver. The causes of subcapsular hematoma were liver tumor rupture (n = 12), trauma (n = 12), iatrogenic complications (n = 9), and spontaneous bleeding (n = 1). The technical and clinical success rates of TAE, blood test results after TAE and additional treatments were evaluated. The patients were divided into either with or without retrograde segmental or lobar portal venous flow on angiography. Technical and clinical success rates and blood test results after TAE were compared between the two groups.
Results: Technical and clinical success rates were 94.1% and 73.5%, respectively. Six patients died within one month of TAE. A repeat TAE was performed in three patients. Surgical removal and hemostasis for subcapsular hematoma were done in four patients. One patient had liver failure. The retrograde portal venous flow was observed in 18 patients. The difference in technical and clinical success rates and blood test results after TAE between the two groups was statistically insignificant.
Conclusion: TAE is an effective and safe treatment for subcapsular hematomas of the liver. The success rates of TAE and liver damage due to TAE did not differ between patients with and without retrograde portal venous flow.

Institute of Medical & Public Health Research, Ilia State University, Tbilisi, Georgia.
Background: The long-term clinical efficacy of intraportal islet transplantation is hampered by islet loss due to inflammation, oxidative stress, and insufficient vascularization. This study explores the venous sac as an alternative implantation site for islet transplantation in large animal models.
Methods: An immunosuppressed, diabetic cynomolgus monkey received allogeneic islet implants in its mesenteric venous sac, with metabolic assessments over 112 days.
Machine learning-based personalized prediction of sperm retrieval in patients with non-obstructive azoospermia prior to microdissection testicular sperm extraction: A multi-center cohort study.

Department of Urology, Peking University First Hospital, Beijing, China.
Background: Non-obstructive azoospermia represents the most severe form of male infertility. The heterogeneous nature of focal spermatogenesis within the testes of non-obstructive azoospermia patients poses significant challenges for accurately predicting sperm retrieval rates.
Objectives: To develop a machine learning-based predictive model for estimating sperm retrieval rates in patients with non-obstructive azoospermia.
Numerical investigations on the oil intercepting performance of area-source pneumatic booms via a coupled DPM and VOF method.

Pneumatic booms offer distinct advantages over traditional structural barriers: not affecting the local vessel navigation and hydrological environment, enhanced mobility and maneuverability, etc. However, their oil interception performance remains insufficiently understood especially for the area-source ones. This study employs a well-validated numerical model based on the coupled VOF and DPM framework, to systematically investigate the plume evolution and oil containment efficiency of near-surface area-source bubble curtains under various aquatic scenarios.

Background: Despite decades of initiatives to increase nursing workforce diversity, gaps persist between patient population and nursing workforce demographics.
Problem: Emphasis on NCLEX pass rates as a program quality indicator, combined with systemic barriers, creates complex challenges that influence admission and progression policies in nursing education. Evidence suggests these factors disproportionately affect underrepresented minority (URM) students, impacting both academic success and workforce diversity.
Non-Sedated Intrauterine Device Experiences Among Transgender and Cisgender Adolescents and Young Adults in the Outpatient Setting.

Division of Adolescent Medicine, Seattle Children's Hospital, Seattle, WA, USA.
Study Objectives: This study compares the demographic characteristics and experiences of three different groups of adolescent and young adults (AYAs) seeking non-sedated intrauterine device (IUD) insertion in the outpatient setting: (1) cisgender individuals, (2) transgender and gender diverse (TGD) individuals receiving gender-affirming testosterone therapy, and (3) TGD individuals not receiving gender-affirming testosterone therapy.
Methods: This retrospective cohort study included AYAs age 13 to 21 years seeking IUD insertion. Data were obtained from the electronic health record via a pre-existing, multi-institutional shared quality improvement (QI) collaborative.
