Objectives: An estimated 1% of endovascular aneurysm repair (EVAR) devices become infected, carrying a high mortality rate. Surgical explantation is recommended and prognosis is guarded. This retrospective cohort analysis focuses on the role of outpatient parenteral antimicrobial therapy (OPAT) in the management of aortic vascular graft infections following EVAR.

Article Synopsis
  • * Researchers determined that microglial-like cells derived from human pluripotent stem cells expressing the disease-causing mutant HTT protein are hyper-reactive, producing increased levels of inflammatory cytokines and reactive oxygen species when stimulated.
  • * The study underscores that while human PSCs can differentiate into microglia regardless of mutant HTT, these microglia exhibit heightened inflammatory responses and greater susceptibility to apoptosis, indicating a potential link to the disease's progression.

The huntingtin (HTT) protein in its mutant form is the cause of the inherited neurodegenerative disorder, Huntington's disease. Beyond its effects in the central nervous system, disease-associated mutant HTT causes aberrant phenotypes in myeloid-lineage innate immune system cells, namely monocytes and macrophages. Whether the wild-type form of the protein, however, has a role in normal human macrophage function has not been determined.

Generalized lymphatic anomaly is a rare, complex, lymphatic anomaly generally involving soft tissues, spleen, and bones. It can lead to focal skeletal fragility and pathologic effusions. A recent prospective trial of sirolimus for complicated vascular anomalies showed partial response in seven patients with generalized lymphatic anomaly treated with sirolimus with a target trough level of 10-15 ng/mL for 1 year (Adams et al).
