Traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation. One sequela of neuroinflammation includes the pathologic hyperphosphorylation of tau protein, an endogenous microtubule-associated protein that protects the integrity of neuronal cytoskeletons. Tau hyperphosphorylation results in protein misfolding and subsequent accumulation of tau tangles forming neurotoxic aggregates. These misfolded proteins are characteristic of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease and can lead to downstream neuroinflammatory processes, including assembly and activation of the inflammasome complex. Inflammasomes refer to a family of multimeric protein units that, upon activation, release a cascade of signaling molecules resulting in caspase-induced cell death and inflammation mediated by the release of interleukin-1β cytokine. One specific inflammasome, the NOD-like receptor protein 3, has been proposed to be a key regulator of tau phosphorylation where it has been shown that prolonged NOD-like receptor protein 3 activation acts as a causal factor in pathological tau accumulation and spreading. This review begins by describing the epidemiology and pathophysiology of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease. Next, we highlight neuroinflammation as an overriding theme and discuss the role of the NOD-like receptor protein 3 inflammasome in the formation of tau deposits and how such tauopathic entities spread throughout the brain. We then propose a novel framework linking traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease as inflammasomedependent pathologies that exist along a temporal continuum. Finally, we discuss potential therapeutic targets that may intercept this pathway and ultimately minimize long-term neurological decline.

This study explores risk transfer options that precarious and marginal urban communities could use to protect themselves from future damages and losses generated by socio-natural hazards and disasters at the individual and community levels. The design is framed within an evidence-based disaster risk reduction(DRR) strategy and follows the case study research approach. We analyze the2018 Neighborhood Approach for DRR programming evaluation carried out in four Latin American cities’ informal settlements and review relevant risk transfer experiences aimed at vulnerable populations. We calculate the pure risk premium for the four cases selected, using a previous catastrophe risk assessment for earthquakes and landslides. We propose three risk transfer options based on our analysis:(1) voluntary collective insurance;(2) structural reinforcement with a comprehensive housing insurance;and(3) hybrid parametric insurance. Risk transfer mechanisms conventionally focus on residual risk management. Here, due to the precariousness of the analyzed urban settings, the proposed alternatives go beyond the management of just residual risk to positively impact the beneficiaries’ quality of life and the reduction of the built environment’s physical vulnerability in the short and medium terms. Our study proposes a prospective estimation of future risk despite the limitations of data availability. This study opens a window to new approaches and proposes a systematic process to design DRR policy aimed at the poor and vulnerable strata of society.
