AI Article Synopsis
- Gross total resection (GTR) of intracranial meningiomas is often curative, but about 20% of patients may need blood transfusions due to surgical blood loss or preoperative anemia.
- A scoping review analyzed 33 studies involving 3009 patients, revealing that headaches were the most common symptom and grade-1 meningothelial meningiomas were the most frequent type.
- The findings suggest that surgical factors, like the extent of blood loss during the operation and existing anemia, can significantly impact the need for blood transfusions in these surgeries.
Article Abstract
Background: Gross total resection (GTR) of intracranial meningiomas is curative in most cases. However, perioperative blood transfusions may be necessary for complex skull bases and/or high-grade meningiomas. Guidelines for blood transfusions during intracranial meningioma surgery remain unclear. This scoping review aims to delineate the main characteristics of patients who underwent intracranial meningioma surgery, the prevalence of the selected patients who required blood transfusions, and common causes for transfusion.
Methods: A scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews guidelines to include studies reporting eligibility, protocols, and potential complications related to blood transfusion within the perioperative management of intracranial meningiomas.
Results: A total of 33 articles encompassing 3009 meningioma patients were included in the study. The most common symptom was headache (18%), and the most frequent type of meningioma was World Health Organization grade-1 meningothelial (50.4%). The lateral supraorbital approach was the most common surgical corridor (59.1%) in skull base meningiomas, and most patients underwent GTR (69%). Blood transfusion was required for 20% of patients, with a mean estimated intraoperative blood loss of 703 mL (ranging from 200 mL to 2000 mL). The main indications for blood transfusion in meningioma surgery were intraoperative blood loss (86%) and preoperative anemia (7.3%).
Conclusion: This scoping found that 20% of the included patients required blood transfusion. It also points out that several factors could influence the necessity for a transfusion, encompassing surgical blood loss, pre-existing anemia, and the surgery's length. This scoping review may provide surgeons with a potential guide to inform their decision-making process regarding blood transfusions during meningioma surgeries.

Aberrant STING activation promotes macrophage senescence by suppressing autophagy in vascular aging from diabetes.
iScience
January 2025
Department of Cardiology, The Second Xiangya Hospital of Central South University, Changsha 410011, China.
Diabetic vascular aging is driven by macrophage senescence, which propagates senescence-associated secretory phenotypes (SASP), exacerbating vascular dysfunction. This study utilized a type 2 diabetes mellitus (T2DM) mouse model induced by streptozotocin injection and a high-fat diet to investigate the role of STING in macrophage senescence. Vascular aging markers and senescent macrophages were assessed , while , high glucose treatment induced macrophage senescence, enhancing senescence in co-cultured vascular smooth muscle cells.

Background: Platelet (PLT) transfusion is an essential strategy to prevent bleeding in children with thrombocytopenia associated to cancer treatment. However, data on optimal pediatric dosing and transfusion thresholds are limited.
Methods: This retrospective study analyzed data from 607 pediatric patients with hematologic malignancies, nonmalignant disorders, and solid tumors who developed hypoproliferative thrombocytopenia during therapy.
Comprehensive Phenotyping of Extracellular Vesicles in Plasma of Healthy Humans - Insights Into Cellular Origin and Biological Variation.

Despite immense interest in biomarker applications of extracellular vesicles (EVs) from blood, our understanding of circulating EVs under physiological conditions in healthy humans remains limited. Using imaging and multiplex bead-based flow cytometry, we comprehensively quantified circulating EVs with respect to their cellular origin in a large cohort of healthy blood donors. We assessed coefficients of variations to characterize their biological variation and explored demographic, clinical, and lifestyle factors contributing to observed variation.
