Objective: To assess if patients treated with omega-3(n-3) polyunsaturated fatty acids (PUFAS) had lower procedural failure rates compared to an untreated population.
Methods And Results: From January 2004 to 2007, 1500 PVAI patients underwent catheter ablation. Two hundred and eighty five (19%) patients were treated with PUFAs. These patients were matched in a nested case controlled analysis. After matching, there were 129 patients in the PUFA group and 129 in the control group. Thirty-five (27.1%) patients in the study group had early recurrence vs. 57 (44.1%) in the control group p-value< 0.0001. Twenty-nine (23.2%) patients in the PUFA group vs. 41 (31.7%) in the non-PUFA group had procedural failure (p-value < 0.003). There were no significant differences in complications in the PUFA and non-PUFA groups.
Conclusion: Patients treated with PUFAs had lower incidences of early recurrence and procedural failure compared to an untreated population.

The global incidence of biliary tract cancer (BTC) is on the rise, presenting a substantial healthcare challenge. The integration of immune checkpoint inhibitors (ICIs) with molecularly targeted therapies is emerging as a strategy to enhance immune responses. However, the efficacy and underlying mechanisms of these treatments in BTC are still largely unexplored.

Background: Robot-assisted thoracoscopic surgery (RATS) is more precise and flexible than video-assisted thoracoscopic surgery (VATS) for early-stage non-small cell lung cancer (NSCLC) treatment. This study compared the early postoperative functional recovery of patients who underwent triportal RATS with that of patients who underwent uniportal video-assisted thoracic surgery (UVATS) for segmentectomy.
Methods: This observational, prospective study included 172 patients with clinical stage I or II peripheral NSCLC who underwent RATS or UVATS segmentectomy.

Background: The swift rise in the prevalence of Alzheimer's disease (AD) alongside its significant societal and economic impact has created a pressing demand for effective interventions and treatments. However, there are no available treatments that can modify the progression of the disease.
Methods: Eight AD brain tissues datasets and three blood datasets were obtained.

Background: Lumen reduction after bioresorbable scaffold implantation has been reported. This study aimed to assess the influence of pre-dilatation with a scoring balloon versus a standard non-compliant balloon prior to implanting a magnesium-based Magmaris bioresorbable scaffold (MgBRS) on lumen measurements using optical coherence tomography (OCT) and on clinical outcomes after 12 months.
Method: In the OPTIMIS-study (Optimal lesion preparation before implantation of a MgBRS in patients with coronary artery stenosis), patients were randomly assigned to pre-dilatation with a scoring balloon or a standard non-compliant balloon before MgBRS implantation.
T-cell Engagers in Prostate Cancer.

Owing to the "cold" tumor immune microenvironment of prostate cancer, immune-targeting agents have shown limited efficacy in patients with advanced prostate cancer, highlighting the need for new therapies with novel mechanisms of action. In this context, T-cell engagers (TCEs), which induce T-cell-mediated killing of cancer cells by binding the CD3 receptor on T cells and a specific tumor antigen expressed on malignant cells, represent a promising therapeutic option. Multiple studies have explored the use of TCEs in previously treated patients with metastatic castration-resistant prostate cancer, and several ongoing trials are currently assessing novel TCEs either as single agents or in combinatorial regimens with molecules with a distinct mechanism of action (eg, androgen receptor pathway inhibitors and other immune-targeting agents).
