Risk profiles of personality traits for suicidality among mood disorder patients and community controls Objective: To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls. Method: We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N). We used logistic regression models adjusted for diagnoses to analyze combinational effects of personality traits on the risk of suicide. Additionally, radar charts display personality profiles for suicidal behaviours by groups. Results: All personality traits were associated with the risk of suicidality with various effect size, except for E that showed protective effect. High N or HA had prominent and independent risk effects on SI and SA. Combinations of high N and low E, or high HA and NS were the risk personality profiles for suicidality. Higher N scores further distinguished SA from SI in mood disorder patients. Conclusion: Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high-risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt. Significant outcomes• Higher scores of neuroticism or harm avoidance were associated with increased risk of suicidal ideation and attempt, and the effect of personality traits was independent of mood disorder diagnosis.• 'High neuroticism low extraversion' or 'high novelty seeking high harm avoidance' was the risk personality profiles for suicidal behaviours.• Higher neuroticism score further distinguishes attempters from ideators among mood disorder patients. Limitations• The sample size in our study was only moderate. It is underpowered to do stratified analysis, such as identifying gender-specific effects.• Personality traits were measured after diagnosis of mood disorders. The stability of personality traits cannot be evaluated. 30

A case of resolving hemorrhagic pancreatitis resulting in massive left perirenal fat necrosis is reported. CT revealed a huge fat-containing mass that was thought to be retroperitoneal liposarcoma before operation. Pancreatitis with perirenal involvement is rarely encountered as a retroperitoneal mass.
