Article Abstract

In recent years, treatment options for patients with advanced biliary tract cancer (BTC) have increased significantly due to the positive results from phase 2/3 clinical trials of immune checkpoint inhibitors, combined with chemotherapy, and molecularly targeted agents. These advances have led to the need for molecular testing to identify actionable alterations and patients amenable to targeted therapies. However, these improvements have brought with them many questions and challenges, including the identification of resistance mechanisms and therapeutic sequences. In this Series paper we aim to provide an overview of the current systemic treatment options for patients with BTC, highlighting disparities in access to innovative treatments and molecular testing across European countries, which lead to inequalities in the possibilities of treating patients with advanced BTC. We also discuss how ongoing European collaborative projects, such as the COST Action Precision-BTC-Network CA22125, supported by COST (European Cooperation in Science and Technology), linked to the European Network for the Study of Cholangiocarcinoma (ENSCCA), can help overcome these disparities and improve the current scenario.

Systemic Delivery of an mRNA-Encoding, Tumor-Activated Interleukin-12 Lock to Eliminate Tumors and Avoid Immune-Related Adverse Events.

Interleukin-12 (IL-12) is a robust proinflammatory cytokine that activates immune cells, such as T cells and natural killer cells, to induce antitumor immunity. However, the clinical application of recombinant IL-12 has been limited by systemic immune-related adverse events (irAEs) and rapid degradation. To address these challenges, we employed mRNA technology to encode a tumor-activated IL-12 "lock" fusion protein that offers both therapeutic efficacy and systemic safety.

Purpose Of Review: Despite major advances in the treatment and prevention of atherosclerotic cardiovascular disease (ASCVD), a substantial burden of residual risk remains Obesity has been redefined as a primary and independent drivers of cardiovascular morbidity and mortality warranting focused attention.

Recent Findings: Obesity is now recognized as a chronic disease and a central contributor to residual cardiovascular risk through mechanisms including systemic inflammation, insulin resistance, dyslipidemia, and endothelial dysfunction. This review addresses the limitations of conventional obesity management and highlights emerging pharmacological therapies targeting the underlying adiposopathy.

Oligomeric proanthocyanidins (OPCs), condensed tannins found plentiful in grape seeds and berries, have higher bioavailability and therapeutic benefits due to their low degree of polymerization. Recent evidence places OPCs as effective modulators of cancer stem cell (CSC) plasticity and tumor growth. Mechanistically, OPCs orchestrate multi-pathway inhibition by destabilizing Wnt/β-catenin, Notch, PI3K/Akt/mTOR, JAK/STAT3, and Hedgehog pathways, triggering β-catenin degradation, silencing stemness regulators (OCT4, NANOG, SOX2), and stimulating tumor-suppressive microRNAs (miR-200, miR-34a).

Background: Pelvic and acetabular fractures, often resulting from high-impact trauma, pose significant challenges due to extensive blood loss and complex surgical procedures. Tranexamic acid (TXA), widely used in elective orthopedic surgeries, offers a potential strategy for managing blood loss. However, its efficacy and safety in pelvic-acetabular trauma surgeries have shown inconsistent results in prior studies.

Vitiligo is a chronic skin disease characterized by white patches caused by the destruction of melanocytes. The most well-known variant is non-segmental vitiligo, where patches are symmetrically distributed across the entire body, with alternating periods of stability and progression. The white patches arise due to an autoimmune reaction in which cytotoxic T-cells attack the melanocytes.
