Purpose: Pancreas transplantation (PT) is a definitive treatment for diabetes mellitus (DM), restoring endogenous insulin secretion and improving glycemic control. Despite its efficacy, PT is less common in South Korea compared to Western nations. This study aims to report the clinical outcomes of PT over 2 decades at a single center, focusing on surgical techniques, complications, and graft survival. Methods: A retrospective analysis of 69 PT recipients at Seoul National University Hospital between January 2002 and December 2023 was conducted. Data on recipient and donor demographics, surgical details, immunosuppressive regimens, and graft outcomes were collected. Graft survival was evaluated using Kaplan-Meier analysis, with subgroup comparisons using the log-rank test. Graft failure was defined as graft removal, PT re-registration, insulin dependence exceeding 0.5 units/kg/day for more than 90 days, or patient death. Results: Among the 69 recipients, 50 (72.5%) had type 1 DM, and 18 (26.1%) had type 2 DM. Simultaneous pancreaskidney (SPK) transplantations comprised 84.1% (n = 58), and pancreas-after-kidney (PAK) transplantations accounted for 10.1%. The 1-year and 5-year death-censored pancreas graft survival rates were 92.7% and 89.6%, respectively, with no significant difference between SPK and PAK (P = 0.330). Graft failure occurred in 10 patients, primarily due to pancreatitis and rejection. Donor-related factors, particularly anoxic brain injury, were significantly associated with lower graft survival (P = 0.045). Conclusion PT outcomes in this cohort align with international standards, emphasizing the importance of donor selection and tailored immunosuppression. Expanding PT indications to include selective type 2 DM patients could benefit South Korea’s PT programs with adequate resource allocation.

Purpose: Takayasu arteritis (TAK) is a rare form of chronic vasculitis that is common in Asian female. As TAK predominantly affects young female with a longer life expectancy than those with atherosclerotic diseases, assessing the specific long-term outcomes of TAK treatment is important. Therefore, this study aimed to evaluate the long-term outcomes and post-procedural complications of surgical and endovascular treatment for TAK. Materials and Methods: This single-center retrospective observational study reviewed 545 consecutive patients diagnosed with TAK between 1983 and 2020 at Seoul National University Hospital. Of these, 56 patients who underwent 73 extracardiac interventions were enrolled in the study. The data included clinical features, angiographic and laboratory findings, treatment modalities, and clinical outcomes. Results: The mean age of the participants was 40.3±20.3 years, with a predominance of female (75.0%). The mean follow-up duration was 147.7±111.6 months. The most common comorbidity was hypertension (n=42, 75.0%), followed by heart failure (n=12, 21.4%). The most frequent symptom of TAK was uncontrolled hypertension (n=36, 64.3%). The renal artery (n=23, 31.5%) was the most frequently revascularized vessel, followed by the supra-aortic branches, including the innominate, subclavian, vertebral, and carotid arteries (n=19; 26.0%). In the endovascular group, the primary patency rates at 5, 10, and 20 years were 42.2%, 31.7%, and 17.0%, respectively. The rates in the surgical group were 84.4%, 75.7%, and 59.0%, respectively. This difference was statistically significant (P<0.001). The difference in the secondary patency rates between the two groups was not statistically significant. The most common early complication (≤1 month) was arterial dissection (n=4, 5.5%), whereas the most prevalent late complication (>1 month) was restenosis, which occurred significantly more frequently in the endovascular group than in the surgical group (55.0% vs.12.1%, P<0.001). Conclusion Surgical and endovascular treatments for TAK are safe. However, restenosis develops more frequently after endovascular treatment compared to surgical treatment, particularly within the first three years. Increased periodic serial monitoring is recommended during this period.

Purpose: Liposarcoma is a mesenchymal neoplasm and comprise 20%–30% of all soft tissue sarcomas, accounting for 1% of all malignancies. This study documented the clinical manifestation and oncological outcomes of dedifferentiated liposarcoma (DDLPS). Materials and Methods: Eleven patients were diagnosed and treated for DDLPS between January 2013 and December 2020. The age, gender, symptom onset, tumor location, magnetic resonance images, surgical margin, and pathologic diagnosis of the identified cohort were reviewed. The time to local recurrence or metastasis, follow-up duration, and the patients’ final status were analyzed. Results: The patients comprised seven male and four female patients with a mean age of 59 years (43–73 years). The tumor location was in the thigh in five, inguinal in two, upper arm in two, forearm in one, and popliteal in one. The average tumor diameter was 12 cm (3.5–27.0 cm). At the time of diagnosis, one patient was American Joint Committee on Cancer stage IB, two were II, four were IIIA, and four were IIIB. Local recurrence occurred in four, and distant metastasis occurred in five. The five-year overall survival of patients with DDLPS was 54.5±17.6%, and four died due to disease progression. Conclusion Primary DDLPS in the extremities is a subtype of liposarcoma with a poorer prognosis than well-differentiated liposarcoma and myxoid liposarcoma.

Lepidium sativum (LS) is an annual plant that has been used for the treatment of many ailments. The ethanol extracts of pinnately-lobed (PL), pinnately-compound (PC), and pinnately-veined (PV) leaves of LS were examined for their total polyphenol and flavonoid contents, and their phenolic acid (namely caffeic acid (CA), p-coumaric acid (PA), and ferulic acid (FA)) contents were determined using reverse-phase high-performance liquid chromatography-photodiode array (HPLC/PDA) analysis. Among the three leaf types, the highest average total polyphenol content was found in PV (79.87 mg GAE/g extract), whereas PC showed the highest average total flavonoid content (53.35 mg QE/g extract). According to the HPLC/PDA results, PV exhibited a high amount of CA (78.60 µg/g extract) and FA (1,722.85 µg/g extract), whereas a high content of PA (258.72 µg/g extract) was detected in PC. Higher amounts of the phytochemical compounds PV and PC might be indicative of their superior biological activities compared to PL. To the best of our knowledge, this study is the first to quantify and compare the total polyphenol, flavonoid, and phenolic acid contents in three different leaf types of LS.
