Multifunctional Nanomedicine for Targeted Atherosclerosis Therapy: Activating Plaque Clearance Cascade and Suppressing Inflammation.
ACS Nano

Atherosclerosis (AS) is a prevalent inflammatory vascular disease characterized by plaque formation, primarily composed of foam cells laden with lipids. Despite lipid-lowering therapies, effective plaque clearance remains challenging due to the overexpression of the CD47 molecule on apoptotic foam cells, inhibiting macrophage-mediated cellular efferocytosis and plaque resolution. Moreover, AS lesions are often associated with severe inflammation and oxidative stress, exacerbating disease progression.

Background: Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a rare and progressive mitochondrial disorder characterized by multi-systemic involvement. This disease manifests in various clinical manifestations, with heart and kidney disorders being among the most common. Accurate diagnosis of MELAS often necessitates a range of complex investigations.

Article Synopsis
- The study focused on identifying situations that lead to metformin-associated lactic acidosis (MALA) in ICU patients and evaluating its preventability.
- A total of 198 MALA cases were assessed, with 19.2% resulting in death; the majority of patients had acute events like dehydration or severe infections that contributed to the condition.
- The findings indicated that MALA is often preventable, highlighting the need for better physician and patient education regarding metformin use during high-risk medical situations.

Introduction: Metformin is a first line treatment for type II diabetes. Cases of metformin-associated lactic acidosis are regularly reported. A direct causal link between metformin overdose and lactic acidosis is not clearly established.
