Priming versus propagating: distinct immune effects of an alpha- versus beta-particle emitting radiopharmaceutical when combined with immune checkpoint inhibition.

Radiopharmaceutical therapy (RPT) enhances tumor response to immune checkpoint inhibitors (ICI) in preclinical models, but the effects of different radioisotopes have not been thoroughly compared. To evaluate mechanisms of response to RPT+ICI, we used NM600, an alkylphosphocholine selectively taken up by most tumors. Effects of Y-, Lu-, and Ac-NM600 + ICIs were compared in syngeneic murine models, B78 melanoma (poorly immunogenic) and MC38 colorectal cancer (immunogenic).

Postoperative Hemorrhage and Venous Thromboembolism in Patients with Pituitary Adenomas Under Acetylsalicylic Acid.

Postoperative hemorrhages (POHs) after pituitary adenoma surgery can have devastating consequences for patients. Many patients take acetylsalicylic acid (ASA) for the primary or secondary prevention of cardiovascular or stroke events. However, the impact of continued low-dose ASA use on the risk of postoperative hemorrhage and the frequency of thromboembolic events after discontinuing ASA in these patients remain poorly understood.

Synergistic Effect in Hybrid Plasmonic Conjugates for Photothermal Applications.

Photothermal conversion efficiency (η) plays a crucial role in selecting suitable gold nanoparticles for photothermal therapeutic applications. The photothermal efficiency depends on the material used for the nanoparticles as well as their various parameters, such as size and shape. By maximizing the light-to-heat conversion efficiency (η), one can reduce the concentration of nanoparticle drugs for photothermal cancer treatment and apply lower laser power to irradiate the tumor.

Risk of Postoperative Hemorrhage After Glioma Surgery in Patients with Preoperative Acetylsalicylic Acid.

Background/objectives: Patients with gliomas show an increased risk of spontaneous hemorrhages throughout the disease. Simultaneously, the number of patients taking acetylsalicylic acid (ASA) for primary and secondary prophylaxis is rising in daily clinical practice, and interrupting ASA intake before elective or emergency intracranial surgery is not always feasible. This study aims to evaluate the risks associated with continuing ASA use perioperatively while focusing on hemorrhage and potential thromboembolic events that may arise from discontinuing ASA, particularly in multimorbid patients undergoing glioma surgery.

Sex differences in overweight and obese patients undergoing high-power short-duration pulmonary vein isolation for atrial fibrillation: an observational cohort study.

Atrial fibrillation (AF) is the most common heart rhythm disorder worldwide. As treatment methods evolve, optimizing personalized therapy based on patient characteristics, such as sex, becomes crucial. This study investigates sex differences in high-power short-duration (HPSD) pulmonary vein isolation (PVI) in overweight and obese patients.
