Department of Defense Medical Examination Review Board Audiogram Screening Comparative Analysis.

Introduction: The Department of Defense Medical Examination Review Board (DoDMERB) plays a pivotal role in the assessment of medical fitness for aspiring military officers. A crucial component of this process is the screening audiogram, designed to evaluate hearing capabilities. However, recent observations of high disqualification rates following screening audiograms led to concerns about their accuracy.

Neutrophils promote VLA-4-dependent B cell antigen presentation and accumulation within the meninges during neuroinflammation.

The success of B cell depletion therapies and identification of leptomeningeal ectopic lymphoid tissue (ELT) in patients with multiple sclerosis (MS) has renewed interest in the antibody-independent pathogenic functions of B cells during neuroinflammation. The timing and location of B cell antigen presentation during MS and its animal model experimental autoimmune encephalomyelitis (EAE) remain undefined. Using a new EAE system that incorporates temporal regulation of MHCII expression by myelin-specific B cells, we observed the rapid formation of large B cell clusters in the spinal cord subarachnoid space.
