In this case study, I consider Mr. A, a Jehovah's Witness with chronic vertebral osteomyelitis in need of surgical debridement. Prior to proceeding to the OR, he was unwilling either to explicitly consent to or refuse blood transfusion, while indicating he was open to transfusion intraoperatively, if the team judged it necessary. Ethics was consulted to determine if it would be morally justifiable for the team to proceed with blood transfusion during the course of surgery without Mr. A's documented consent to being transfused. I argue that in this case, what might be termed indirect consent-namely, delegating decision-making regarding some possible course of action without explicitly consenting to the course of action itself-may be sufficient for discharging the clinician's ethical obligation to obtain consent. Identifying information has been changed or omitted to protect patient confidentiality.

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.

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.
