Abstract Background Suicide is the tenth leading cause of death in the United States, with over half of cases involving firearms. Despite research indicating negative effects of exposure to suicide, there is little research on who typically finds the body of the suicide decedent. Understanding who finds the body of the suicide decedent may be important to understand trauma and mental health effects. Findings Of the 332 people who died by suicide in El Paso County, Colorado, 182 (55%) used firearms. Those who died by firearm suicide were more likely to be male (83.5% vs. 67.3%) have military affiliation (39.0% vs. 19.3%) and were less likely to have a known mental health diagnosis (47.3% vs. 64.7%) compared to those who died from other means. Most suicide decedents were found by a family member or friend (60.2%). The remaining decedents were found by a stranger/acquaintance (21.0%) or a first responder (22.4%) One-fifth of suicides involved forced witnessing (19%) and the majority were already deceased when the body was discovered (73.2%). Conclusions While most suicide decedents are discovered by a family member or a friend, it is unknown what the bereavement and trauma-related outcomes are among people who discover a suicide decedent who has died by violent means, especially by firearms. Further studies exploring who discovers suicide decedents and targeted postvention strategies for supporting impacted family, friends, first responders, and strangers are needed.

Biomarkers of chronic inflammation (such as C-reactive protein) have long been associated with cardiovascular disease and mortality; however, biomarkers involved in antiviral cytokine induction and adaptive immune system activation remain largely unexamined. We hypothesized the cytokine interferon gamma inducible protein 10 (IP-10) would be associated with clinical and subclinical cardiovascular disease and all-cause mortality in African Americans. We assessed these associations in the Jackson Heart Study (JHS) cohort and the REasons for Geographic and Racial Differences in Stroke (REGARDS) study. There was a modest association of IP-10 with higher odds of left ventricular hypertrophy (OR = 1.20 (95% confidence interval (CI) 1.03, 1.41) per standard deviation (SD) higher natural log-transformed IP-10 in JHS). We did not observe associations with ankle brachial index, intima-media thickness, or arterial calcification. Each SD higher increment of ln-transformed IP-10 concentration was associated with incident heart failure (hazard ratio (HR) 1.26; 95% CI 1.11, 1.42, p = 4x10-4) in JHS, and with overall mortality in both JHS (HR 1.12 per SD, 95% CI 1.03, 1.21, p = 7.5x10-3) and REGARDS (HR 1.31 per SD, 95% CI 1.10, 1.55, p = 2.0 x 10-3), adjusting for cardiovascular risk factors and C-reactive protein. However, we found no association between IP-10 and stroke or coronary heart disease. These results suggest a role of IP-10 in heart failure and mortality risk independent of C-reactive protein. Further research is needed to investigate how the body's response to chronic viral infection may mediate heart failure and overall mortality risk in African Americans.
