The present study aimed to evaluate if sepsis sensitizes behavioural and biochemical responses induced by m‐amphetamine. For this, Wistar rats were submitted to the cecal ligation and puncture. After 30 days of cecal ligation and puncture procedure, the animals were submitted to a single intraperitoneal injection of saline or m‐amphetamine (.25,.50, or 1.0 mg/kg). Locomotor behaviour was assessed 2 h after the administration. Interleukin (IL)‐1β, IL‐6, IL‐10, tumour necrosis factor‐α, dopamine‐cAMP‐regulated phosphoprotein of 32,000 kDa (DARPP‐32) and neuronal calcium sensor (NCS‐1) levels were evaluated in the frontal cortex, hippocampus and striatum. Also, brain‐derived neurotrophic factor (BDNF), neuronal growth factor and glial‐derived neurotrophic factor levels were assessed in the hippocampus. M‐amphetamine alone (.25 and 1.0 mg/kg) increased rats' locomotion and exploratory behaviour compared with the Sham + Sal. Animals from the cecal ligation and puncture + m‐amphetamine (.5 and/or 1.0 mg/kg) group showed an increase in locomotion, exploratory and risk‐like behaviour when compared with the Sham + Saline group and with its respective Sham groups. Cecal ligation and puncture increased interleukin levels compared with the Sham + Sal. However, cecal ligation and puncture animals that received m‐amphetamine (1 mg/kg) increased even more, these inflammatory parameters compared with the Sham + Sal and the cecal ligation and puncture + saline group. M‐amphetamine at lower doses increased neurotrophic factors, but higher doses decreased these parameters in the brain of cecal ligation and puncture rats. M‐amphetamine dose‐dependently increased DARPP‐32 and NCS‐1 levels in cecal ligation and puncture rats in some structures. In conclusion, these results demonstrate that sepsis sensitizes behavioural amphetamine responses while inducing inflammatory and neurotrophic vulnerability in the cecal ligation and puncture model.

- Abstract
The COVID-19 pandemic resulted in drastic disruptions to lives and possible pernicious impacts on mental health, including suicidality. Understanding these relations, as well as impacts on at-risk populations, is essential. The present study examined changes in daily behaviors and cognitions after the implementation of physical/social distancing mandates in individuals with symptoms of suicide crisis syndrome (SCS) and/or suicidal ideation. Adults (N= 5,528) across 10 countries completed online self-report measures. There were significant main effects of time and various configurations of interactions between time, SCS, and suicidal ideation in predicting behaviors (outdoor and social engagements) and cognitions (thoughts about health, finances, and living situation). Cross-culturally, individuals with more severe SCS symptoms generally had the largest changes in behaviors and cognitions, though this effect was not replicated across all countries. Overall, these findings highlight the implications of the potentially mutually exacerbating influences of routine disruptions and suicide risk and the importance of examining associations cross-culturally.

- Abstract
Aim: To investigate the factor structure, reliability, and validity of the Brazilian version of the Abbreviated Suicidal Narrative Inventory (SNI-38)., Methods: We used an anonymous online questionnaire of the SNI-38 and self-report measures administered between November 2020 and October 2021 in the Brazilian community. Participants were recruited through social media advertisements. Confirmatory factor analysis was carried out to test the factor structure of the SNI-38. In addition, we examined internal consistency, and convergent validity against stressful life events, the suicide crisis syndrome, suicidal ideation, and suicide attempts., Results: 2660 participants were included. The eight-factor model SNI-38 had a good model fit (χ2[637] = 7,473.98, p < .001, CFI = .99, TLI = .99, RMSEA = .07, SRMR = .06); all items were significantly and positively loaded onto their respective factors (factor loadings ≥ .45). Reliability was good to high in all subscales except goal disengagement. Additionally, all subscales - except goal disengagement - were correlated positively which the suicide crisis syndrome, stressful life events, lifetime/past-month suicidal ideation, and lifetime suicide attempts., Conclusions: These findings provide preliminary support for the validity of the Brazilian version of the SNI-38, being an appropriate and valid tool for measuring suicidal narrative among Brazilian samples., Competing Interests: The authors report no conflicts of interest.

- Abstract
Objective: To examine the factor structure, reliability, and validity of the Brazilian version of the Suicide Crisis Inventory (SCI-2) among Brazilian adults., Methods: The SCI-2 was cross-culturally adapted into Portuguese and administered to 2,265 individuals in the Brazilian community. Confirmatory factor analyses, internal consistency, and convergent and criterion validity against the suicidal narrative, stressful life events, suicidal ideation, and suicide attempts were examined., Results: The revised one-factor model of the SCI-2 resulted in adequate, but not optimal, model fit (χ2[1539] = 31,442.79, p < .001, CFI = .99, TLI = .99, RMSEA = .09, SRMR = .05). The revised five-factor model, on the other hand, demonstrated good fit (χ2[1529] = 14,174.86, p < .001, CFI = 1.00, TLI = 1.00, RMSEA = .06, SRMR = .04). Comparison of these two models indicated that the five-factor exhibited a superior model fit to the one-factor model. The SCI-2 total and subscales showed strong internal consistency, good convergent, and criterion validity in relation to stressful life events, suicidal narrative (except goal disengagement subscale), suicidal ideation, and suicide attempts., Conclusions: These findings indicate that the Brazilian version of the SCI-2 is a valid tool for measuring symptoms of the Suicide Crisis Syndrome., Competing Interests: The authors report no conflicts of interest.
