AI Article Synopsis
- The study looked at using CT scans and medical information to predict a specific tumor pattern in liver cancer called VETC and how it affects patient recovery.
- Researchers analyzed data from 243 liver cancer patients who had surgery after getting CT scans.
- They found some important signs, like high bilirubin levels and certain tumor features, that could indicate a higher chance of the cancer returning after surgery.
Article Abstract
Purpose: To explore the capability of preoperative CT imaging features, in combination with clinical indicators, for predicting vessels that encapsulate tumor clusters (VETC) pattern and prognosis in hepatocellular carcinoma (HCC).
Materials And Methods: From January 2015 to May 2022, patients with HCC who underwent curative resection and preoperative enhanced CT were retrospectively included. Clinical indicators and imaging featuresassociated with the VETC pattern were determined by logistic regression analyses. The early recurrence (ER) rate was determined using the Kaplan-Meier survival curve. Factors associated with ER after surgical resection were identified by Cox regression analyses.
Result: A total of 243 patients with HCCwere evaluated. The total bilirubin > 17.1 μmol/L (odds ratio [OR] 3.43, 95 % Confidence Interval [CI] 1.70, 6.91, p = 0.001), serum α-fetoprotein > 100 ng/mL (OR 2.41, 95 % CI 1.25, 4.67, p = 0.009), intratumor artery (IA) (OR 2.00, 95 % CI 1.04, 3.86,p = 0.039) and arterial peritumoral enhancement (OR 2.60, 95 % CI 1.13, 5.96, p = 0.025) were independent risk factors for VETC-HCC. The VETCstatus andCT feature ofIA were associated with an increased risk of recurrence, with a shorter median RFS, compared to those without these factors (p < 0.001 and p = 0.019, respectively). In multivariable Cox regression analysis, the VETC(hazard ratio [HR] 2.60, 95 % CI 1.66, 4.09, p < 0.001), morphological patterns of confluent multinodular growth (HR 1.79, 95 % CI 1.10, 2.91,p = 0.019), the number of the tumors (≥2) (HR 2.69, 95 % CI 1.56, 4.65, p < 0.001), and the IA (HR 1.73, 95 % CI 1.12, 2.66, p = 0.013) were independent predictors of ER in patients with HCC after surgical resection.
Conclusion: Preoperative CT features combined with clinical indicators could predict VETC pattern, and the CT features, along with VETC status, were of prognostic significance for early postoperative recurrence in patients with HCC.
Clinical Relevance Statement: Preoperative CT features combined with clinical indicators could predict VETC pattern, and the CT features, along with VETC status, were of prognostic significance for early recurrence in patients with HCC after surgical resection.

Restenosis, the re-narrowing of blood vessels after drug-coated balloons (DCBs), remains a major clinical issue. While rapamycin is the current clinical option for preventing restenosis due to its effectiveness and low toxicity, its delivery is limited by poor tissue absorption and rapid clearance, leading to suboptimal drug retention. Here, we developed the adhesive-polyelectrolyte-coated poly(lactic-co-glycolic acid) (PLGA) particles using in-situ UV-triggered polymerization, encapsulating rapamycin.

Background And Objective: Cerebral aneurysms occur as balloon-like outpouchings in an artery, which commonly develop at the weak curved regions and bifurcations. When aneurysms are detected, understanding the risk of rupture is of immense clinical value for better patient management. Towards this, Fluid-Structure Interaction (FSI) studies can improve our understanding of the mechanics behind aneurysm initiation, progression, and rupture.

Endovascular aneurysm repair (EVAR) plays a crucial role in the treatment of abdominal aortic aneurysm (AAA) in the clinic, but the aneurysm remains in the patient's body after surgery, continuing to pose a risk of progression. Cycloastragenol (CAG) is proven to be an effective anti-AAA drug, and its vascular protective effects can be further improved when the hydrophobic CAG is encapsulated into nano-sized formulations to enhance its bioavailability. In this context, this study developed an extravascular patch hydrogel loaded with CAG nanostructured lipid carriers and a hydrophilic drug of doxycycline hydrochloride (DOX).

Background: Venous malformations (VMs), predominantly arising from activating mutations of tyrosine kinase receptor TIE2 within endothelial cells (ECs), are characterized by dilated and tortuous vessels with a paucity of perivascular cells. The mechanisms of interaction between mutant ECs and perivascular cells remain largely elusive.
Objectives: To investigate the characteristics of extracellular vesicles (EVs) from VM ECs, especially their carried miRNAs and their roles in the crosstalk between ECs and perivascular cells in VM pathogenesis.

Background: The value of Liver Imaging Reporting and Data System (LI-RADS) radiological features and tumor three-dimensional volumetric quantification in preoperative magnetic resonance imaging (MRI) for predicting the vessels encapsulating tumor clusters (VETC) pattern of solitary hepatocellular carcinoma (HCC) is unknown. This study aimed to assess the value of these indicators for predicting the VETC pattern of solitary HCC.
Methods: In total, 36 patients with HCC were selected from a cohort containing 126 patients for further data evaluation.
