AI Article Synopsis
- The study aimed to compare the safety and effectiveness of two types of coil embolizations—hydrogel coils and bare platinum coils—when used with LVIS stents to treat acutely ruptured wide-necked intracranial aneurysms.
- After reviewing data from 89 patients using hydrogel coils and 145 using platinum coils, the researchers found no significant differences in immediate postoperative results or follow-up outcomes for both groups.
- However, the hydrogel coil group had a significantly lower rate of early rebleeding compared to the platinum coil group, suggesting that hydrogel coils may enhance the safety of treating these aneurysms.
Article Abstract
Purpose: To compare the safety and efficacy of low profile visualized intraluminal support (LVIS) stent-assisted hydrogel coil embolization and LVIS stent-assisted bare platinum coil embolization for acutely ruptured wide-necked intracranial.
Methods: 89 patients who underwent LVIS stent-assisted hydrogel coil embolization (hydrogel coil group) and 145 patients who underwent LVIS stent-assisted bare platinum coil embolization (platinum coil group) were retrospectively reviewed after 1:2 propensity score matching (PSM). Procedure-related complications, clinical and angiographic follow-up outcomes were compared between the two groups.
Results: All baseline characteristics were equivalent between hydrogel coil group and platinum coil group after PSM. There were no statistical differences in immediate postoperative embolization results, clinical and angiographic follow-up outcomes between the two groups (P = 0.514, P = 0.323 and P = 0.949, respectively). Intraprocedural aneurysm rupture, intraprocedural thrombosis and postprocedural thrombosis occurred in 2 patients (2.2%, 2/89), 1 patient (1.1%, 1/89) and 1 patient (1.1%, 1/89) of the hydrogel coil group compared with 1 patient (0.7%, 1/145), 1 patient (0.7%, 1/145) and 2 patients (1.4%, 2/145) of the platinum coil group, respectively (P = 0.559, P = 1.000 and P = 1.000). Nevertheless, the rate of postprocedural aneurysm early rebleeding in the hydrogel coil group was significantly lower than that in the platinum coil group (0.0% vs 4.8%, P = 0.046).
Conclusion: LVIS stent-assisted hydrogel coil embolization may reduce the risk of aneurysm early rebleeding compared with LVIS stent-assisted bare platinum coil embolization for the treatment of acutely ruptured wide-necked intracranial aneurysms, which implies that hydrogel coil may improve the safety of stent placement for ruptured intracranial aneurysms.

Article Synopsis
- Statin therapy during coil embolization for intracranial aneurysms (IAs) may lower the rates of aneurysm recurrence and the need for retreatment.
- A post hoc analysis of data from the Hydrogel Endovascular Aneurysm Treatment Trial showed that patients on statins had a recurrence rate of 3.8%, compared to 10.7% in those not on statins.
- Statin use was particularly effective in patients with unruptured aneurysms, significantly reducing recurrence compared to nonstatin users, while having no measurable benefit for ruptured aneurysms.

Article Synopsis
- Oil palm kernel expeller dietary fiber (OPKEDF) has potential benefits in food applications but is underutilized due to poor hydration properties; modifications like enzymolysis and hydroxypropylation or crosslinking can enhance these properties.
- These modifications can increase the soluble fiber content and improve the water-retention and structural properties of egg white protein gel (EWPG), resulting in changes in its hardness, chewiness, gumminess, and transparency.
- However, while modified OPKEDF shows promise in improving gel properties, further research is needed to evaluate its nutritional value, scalability, and cost-effectiveness in food industries.

Background: Extending the distal sealing zone into the external iliac artery is sometimes necessary during endovascular abdominal aortic repair. As the use of an iliac branch device is contingent upon certain anatomical requirements, the application of this device is not universal. Herein, we present an alternative method to preserve hypogastric artery perfusion using a physician-modified fenestrated (PMF) AFX limb (Endologix, Inc.

Aquatic environments host various living organisms with active molecular systems, such as the enzymes in the thylakoid membrane that realise photosynthesis. Various challenges in achieving artificial photosynthesis, such as water splitting, have been studied using both inorganic and organic molecules. However, several problems persist, including diffusion-limited reactions and multiple redox reactions in the liquid phase.
