Objectives: The objectives of the study are twofold: 1) to propose a set of criteria for virtually evaluating different types of reconstructions for mandibular defects during surgical planning, and 2) to prospectively apply the criteria to a series of mandibular reconstructions to select the optimal flap.
Materials And Methods: Clinically relevant assessment criteria were selected, including volumetric overlap, Haussdorf-95, bony contact, ramus/symphysis angles, and dental implantability. In 2021, 21 consecutive patients undergoing mandibular reconstructions were consented to the study.
Human genetics implicate defective myeloid responses in the development of late-onset Alzheimer disease. A decline in peripheral and brain myeloid metabolism, triggering maladaptive immune responses, is a feature of aging. The role of TREM1, a pro-inflammatory factor, in neurodegenerative diseases is unclear.

Non-steroidal anti-inflammatory drugs, which inhibit the cyclooxygenase enzymes COX-1 and COX-2, reduce the risk of developing Alzheimer's disease in normal ageing populations. This preventive effect coincides with an extended preclinical phase that spans years to decades before onset of cognitive decline.

For example, microglia clear misfolded proteins, elaborate trophic factors, and regulate and terminate toxic inflammation. In Alzheimer's disease (AD), however, beneficial microglial functions become impaired, accelerating synaptic and neuronal loss.
