Objective:
The objective of this study is to evaluate the feasibility and safety of renal artery embolization (RAE) via transradial access (TRA) in patients with renal angiomyolipoma (AML) or renal hemorrhage.
Materials and Methods:
Data were collected for this prospective single-center study from 50 patients (51 ± 12 years; male:female, 11:39) who underwent RAE for renal AML (n = 46) or renal hemorrhage (n = 4) between November 2020 and January 2024. Patients with a Barbeau D waveform or a radial artery diameter of <1.5 mm were excluded. Technical success in patients with renal AML and renal hemorrhage was defined as achieving selective catheterization of the culprit artery with embolization, leading to flow stasis and the absence of bleeding evidence, respectively. Clinical success was indicated by a reduction in AML size on follow-up CT scans and the absence of bleeding signs without necessitating additional RAE. The EuroQol 5-Dimension 5-level (EQ-5D-5L) questionnaire was utilized to assess health-related quality of life (HRQoL).
Results:
In one patient with AML, embolization could not be performed following selective catheterization and angiography due to the lack of visible tumor vascularity, resulting in a technical success rate of 98% (49/50). The clinical success rate was 96% (48/50 patients). No instances of TRA failure, conversion to transfemoral access (TFA), or hemostasis failure were noted.During the follow-up period, no major adverse events associated with the RAE occurred. Two patients exhibited asymptomatic radial artery occlusion, and one patient displayed asymptomatic partial thrombosis of the renal artery at the first follow-up visit. The EQ-5D-5L scores were 0.90 (95% confidence interval [CI]: 0.86–0.95) within 24 hours post-procedure and 0.89 (95% CI: 0.85–0.92) at the first follow-up (P = 0.332).
Conclusion
TRA is a feasible and safe approach for performing RAE in patients with renal AML or hemorrhage. RAE performed using TRA demonstrated high HRQoL outcomes and may serve as a viable alternative to TFA for performing RAE.

Acanthamoeba is an opportunistic pathogen that causes Acanthamoeba keratitis, granulomatous amoebic encephalitis, and other cutaneous diseases. The life cycle of Acanthamoeba consists of 2 stages of trophozoites and cysts. Under adverse environmental conditions, Acanthamoeba encysts, while the conditions become favorable for growth, it reverts to the trophozoite form. Acanthamoeba excystation is crucial for its proliferation and can lead to recurrent infections after incomplete treatment. To identify the factors involved in excystation, A. castellanii was subjected to either encystation- or excystation-inducing conditions, and gene expression profiles were compared using mRNA sequencing. A. castellanii samples were collected at 8 h intervals for analysis under both conditions. Differentially expressed gene analysis revealed that 1,214 and 1,163 genes were upregulated and downregulated, respectively, by more than 2-fold during early excystation. Five genes markedly upregulated in early excystation (ACA1_031140, ACA1_032330, ACA1_374400, ACA1_275740, and ACA1_112650) were selected, and their expression levels were confirmed via real-time PCR. Small interfering RNA (siRNA) targeting these 5 genes was transfected into Acanthamoeba and gene knockdown was validated through real-time PCR. The silencing of ACA1_031140, ACA1_032330, ACA1_374400, and ACA1_112650 inhibited excystation and suggested that these genes might be essential for excystation. Our findings provide valuable insights for suppressing Acanthamoeba proliferation and recurrence.

Background/Aims:
Tenofovir disoproxil fumarate (TDF) is known to have a lipid-lowering effect. This is in contrast to tenofovir alafenamide (TAF), which has a lipid-neutral effect. Therefore, concerns have been raised as to whether these differences affect long-term cardiovascular risk. Here, we aimed to evaluate the long-term risk of cardiovascular events in chronic hepatitis B (CHB) patients treated with TAF or TDF.
Methods:
We retrospectively analyzed 4,124 treatment-naïve CHB patients treated with TDF (n=3,186) or TAF (n=938) between 2012 and 2022. The primary outcome was a composite endpoint of major adverse cardiovascular events (MACE), including myocardial infarction, ischemic stroke, and hospitalization for unstable angina or heart failure. Serial changes in lipid profiles between two treatments were also explored.
Results:
The median age of the patients was 50.6 years, and 60.6% of the patients were male. At baseline, 486 (11.8%) and 637 (15.4%) of the patients had dyslipidemia and fatty liver, respectively. A total of 42 MACE occurred, with an annual incidence of 0.2%/100 person-years (PYs). At 1, 3, and 5 years, the cumulative risk of MACE was 0.4%, 0.8%, and 1.2% in patients treated with TDF, and 0.2%, 0.7%, and 0.7% in patients treated with TAF, respectively (p=0.538). No significant differences in the risk of MACE were observed between TDF and TAF. A multivariable analysis found that current smoker and a history of cardiovascular events were risk factors associated with an increased risk of MACE.
Conclusions
Patients treated with TAF had comparable risks of cardiovascular outcomes, defined as MACE, as patients treated with TDF.
