Evaluating the Safety of Stent-Assisted Endovascular Treatment for Unruptured Cerebral Aneurysms in Older Adults: Emphasizing the Role of Antiplatelet Therapy. | LitMetric

AI Article Synopsis

  • The study compared outcomes and safety in patients aged ≥75 years versus those aged <75 years undergoing stent-assisted treatment for unruptured cerebral aneurysms, focusing on antiplatelet therapy.
  • Among 632 patients, the primary outcomes (thromboembolic events, bleeding, or death) showed no significant differences between the two age groups, with similar rates of events over time.
  • The findings suggest that age alone should not be a strict criterion against stent-assisted treatment for unruptured aneurysms.

Article Abstract

Introduction: This study aimed to compare the outcomes and safety in patients aged ≥75 years and those aged <75 years who underwent stent-assisted endovascular treatment for unruptured cerebral aneurysms, specifically focusing on perioperative antiplatelet therapy (APT).

Methods: This multicenter retrospective study comprised patients who underwent stent-assisted coiling (SAC) or flow diverter stent (FDS) placement for unruptured cerebral aneurysms. The primary outcome was defined as the composite outcomes of perioperative thromboembolic events, bleeding events, or death.

Results: Among 632 patients, 533 (84.3%) were aged <75 years and 99 (15.6%) were aged ≥75 years. No significant differences were observed in the dual APT duration. The primary outcome occurred in 14.3% of patients aged <75 years and in 14.1% of those aged ≥75 years, with no significant difference (p = 1.0). The composites of the primary outcome, including thromboembolic events, bleeding events, and death differed insignificantly. Similar findings were observed when the primary outcomes for SAC (12.7% vs. 11.5%, p = 0.95) and FDS (17.5% vs. 18.4%, p = 1.0) were analyzed. The 30-day, 1-year, and 2-year cumulative event-free survival rates for the primary outcome were 89.5, 87.2%, and 85.2%, respectively, in patients aged <75 years, and 90.9%, 88.7%, and 87.0%, respectively, in those aged ≥75 years. These trends were similar (log-rank test, p = 0.92).

Conclusion: No significant differences were observed in the rates of the primary outcomes between patients aged <75 years and those aged ≥75 years. Therefore, refraining from stent-assisted treatment for unruptured aneurysms based solely on age might be inappropriate.

Background/aims: Biliary obstruction drainage in patients with hepatocellular carcinoma (HCC) is associated with symptom palliation, improved access to chemotherapy, and improved survival. Stent placement and exchange via endoscopic retrograde cholangiopancreatography biliary drainage risk traversing the HCC, a hypervascular tumor and causing bleeding. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) potentially prevents procedure-related bleeding.

Objective: The objective of this study is to synthesize and comprehensively characterize a novel iodine-containing coordination compound, di-aminopropionic acid hydrogen tri-iodide. This involves determining its structural, physicochemical, and thermal properties, as well as evaluating its antimicrobial activity against a range of bacterial strains, including multidrug-resistant pathogens. The aim is to explore the potential of this compound as a candidate for developing new antibacterial agents to address the challenge of antibiotic resistance.

Objective: Retinopathy of prematurity (ROP) is a leading cause of preventable childhood blindness in preterm infants with low birth weight. The efficacy and safety of prophylactic agents, including vitamin A, propranolol and lipids, in reducing ROP incidence remain unclear. This systematic review and meta-analysis evaluated the effectiveness and safety of these agents in preventing ROP.

Purpose: The clinical benefits of pyrotinib plus taxanes or vinorelbine have not been studied systemically. Consequently, we conducted a prospective evaluation to assess the efficacy and safety of pyrotinib plus taxanes or vinorelbine in patients with human epidermal growth factor 2 (HER2)-positive metastatic breast cancer (MBC).

Methods: Patients with HER2-positive MBC were included to receive pyrotinib combined with taxanes or vinorelbine in Jiangsu Cancer Hospital.

Purpose: Ipatasertib is a selective inhibitor of Akt, a frequently activated protein kinase that plays a critical role in human cancers. The current clinical trial aimed to assess the pharmacokinetic properties, safety, and tolerability of ipatasertib administered to Chinese patients with locally advanced or metastatic solid tumors.

Methods: A Phase I, single-arm, open-label study was performed in Chinese patients with locally advanced or metastatic solid tumors for whom standard therapy either does not exist or has proven ineffective.
