Increased C-reactive protein concentration and suicidal behavior in people with psychiatric disorders: A systematic review and meta-analysis

Objective: Suicide is a leading cause of death worldwide. Identifying factors associated with suicidality (suicidal ideation [SI]/suicidal behavior) could increase our understanding of the pathophysiological underpinnings of suicide and improve its prevention. Methods: We conducted a systematic review (PubMed/PsycInfo/Cochrane databases, up to September 2020) and random-effect meta-analysis including observational studies comparing peripheral C-reactive protein (CRP) levels in […]

The associations between suicide‑related behaviors, prefrontal dysfunction in emotional cognition, and personality traits in mood disorders

Suicide is a serious public health problem, and it is urgent to identify biomarkers associated with suicide to prevent it. We aimed to clarify the association across suicidal behavior, personality traits, and brain activation by emotional stimulation tasks using near-infrared spectroscopy (NIRS) in patients with mood disorders. 11 mood disorder patients with a history of […]

The effect of long-term stress on hippocampus and the involvement in the pathophysiological and psychological disorders, suicide, and alcohol use disorder

The hyperactivity of the HPA axis due to long-term stress results in an abnormally high level of glucocorticoids. A limbic system structure, the hippocampus has the highest number of receptor sites for glucocorticoids. Thus, making it highly vulnerable to damage during elevated levels of glucocorticoids, through neurotoxicity and metabolic challenges. In addition, this paper largely […]
