Intrahepatic macrophages in nonalcoholic steatohepatitis (NASH) are heterogenous and include proinflammatory recruited monocyte-derived macrophages. The receptor for advanced glycation endproducts (RAGE) is expressed on macrophages and can be activated by damage associated molecular patterns (DAMPs) upregulated in NASH, yet the role of macrophage-specific RAGE signaling in NASH is unclear. Therefore, we hypothesized that RAGE-expressing macrophages are proinflammatory and mediate liver inflammation in NASH.

We provide an overview of recent advances in the understanding of EV biogenesis, cargo selection, recipient cell effects, and key considerations in isolation and characterization techniques. Studies on the physiological role of EVs have relied on cell-based model systems due to technical limitations of studying endogenous nanoparticles in vivo .

- - Obesity significantly increases the risk of severe COVID-19 outcomes, with a 52% higher risk for admission to ICUs and a notable association with higher mortality rates.
- - The study analyzed data from over 3.1 million patients across 167 studies, highlighting that factors like age, gender, and existing health conditions also influence the severity and mortality rates in obese COVID-19 patients.
- - The research underscores the importance of considering obesity and related health issues in managing COVID-19, as they contribute to worse outcomes for affected individuals.
Neurologic complications are a hallmark of infective endocarditis (IE). IE leading to intracranial abscess has an unfavorable prognosis. A 17-year-old boy with a past medical history of aortic valve replacement presented with fever and seizure.

We present the case of opiate withdrawal-induced psychosis in a 25-year-old married male patient without any prior psychiatric history of illness, family history, or past hospitalization records. The patient presented with psychotic symptoms such as irritability, delusions of parasitosis, and auditory and visual hallucinations at the time of hospitalization.
