A case study is presented of a 22-year-old student mass murderer who stabbed or shot to death 6 college students and wounded 14 others. Because he left a lengthy autobiographical "manifesto" and social media posts, and an extensive law enforcement investigation ensued, a significant amount of information exists to examine the case. The assailant presents a complex diagnostic and psychodynamic picture, including likely features of autism spectrum disorder, narcissism, psychopathy, and depression. A predominant theme is the role of extreme social isolation and severe, pathological envy, fueling the eventual attacks. With the benefit of hindsight, prevention strategies are discussed, and the challenges in identifying and treating insidious, potentially destructive envy. Retrospective threat assessments of the subject on the WAVR-21 V3 (Workplace Assessment of Violence Risk, Version 3) are presented at 3 one-year intervals leading up to the mass murders as he traversed the pathway to predatory violence.
In breast cancer patients, increasing eIF4E overexpression in the cancer specimens correlates with higher VEGF levels and MVD counts. Patients whose tumors had high eIF4E overexpression had a worse clinical outcome, independent of nodal status. Thus, eIF4E overexpression in breast cancer appears to predict increased tumor vascularity and perhaps cancer dissemination by hematogenous means.
Monocyte activation in response to recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) was examined in vitro in septic shock patients. These monocytes exhibited a greater respiratory burst activity than monocytes from healthy subjects; the response to secondary stimulation with bacterial stimuli was attenuated. GM-CSF restored the ability of monocytes to respond appropriately to secondary stimulation. Expression of certain integrin adhesion molecules, L-selectin, and Fcgamma receptors was increased on monocytes of septic shock patients; expression of CD11c was reduced. GM-CSF up-regulated integrin expression and decreased L-selectin, FcgammaRII, and FcgammaRIII expression. Septic patients exhibited greater biologic activity of monocyte tissue factor than did healthy subjects. Priming monocytes with GM-CSF accelerated tissue factor activation following stimulation with lipopolysaccharide and bacterial culture supernatant. Certain parameters of monocyte function may be restored by exposure to GM-CSF. This benefit may be offset by an increase in monocyte procoagulant activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
