Suicide risk and childhood trauma in individuals diagnosed with posttraumatic stress disorder

Abstract Introduction Posttraumatic stress disorder (PTSD) develops after exposure to a potentially traumatic event. Its clinical condition may lead to the development of risk behaviors, and its early detection is a relevant aspect to be considered. The aim of this study was to assess the association between childhood trauma and suicide risk in individuals with PTSD. Method This was a cross-sectional study conducted with individuals aged 18 to 60 years who were evaluated at a mental health research outpatient clinic. PTSD diagnosis and suicide risk identification were performed using specific modules of the Mini International Neuropsychiatric Interview (MINI-Plus). The Childhood Trauma Questionnaire (CTQ) was used to evaluate traumatic events in childhood. Results Of the 917 individuals evaluated, 55 were diagnosed with PTSD. The suicide risk prevalence in individuals with PTSD was 63.6%. Emotional neglect and emotional abuse scores tended to be higher in the suicide risk group (p<0.2). Conclusion Our findings showed a higher prevalence of suicide risk in individuals with PTSD and support the hypothesis that the investigation of childhood traumatic experiences, especially emotional neglect and abuse, may help in the early detection of suicide risk in individuals with PTSD

Well-being and associated factors among elementary school teachers in southern Brazil

ABSTRACT Purpose: to verify the prevalence of well-being and its association with sociodemographic features, health and work-related conditions, and vocal behavior in elementary school teachers in the city of Pelotas, RS. Methods: a cross-sectional observational study with 575 teachers from urban and rural areas. The participants answered a structured questionnaire that included items on sociodemographic, health and work-related conditions. The Faces Scale (Andrews) was used to evaluate their psychological well-being. The Vocal Behavior Profile verified occurrences of abuse and vocal misuse. Poisson regression was used for the multivariate analysis. Results: of the total sample, 79.5% of teachers experienced well-being. It was observed that vocal behavior profile was significantly associated with well-being, and the number of students in the classroom showed a trend towards significance. Conclusion: most teachers had a satisfactory well-being perception. Moreover, a lower well-being perception in the teaching population was mainly related to abusive vocal behavior and, less clearly, to the high number of students per classroom

A New Device for Step-Down Inhibitory Avoidance Task—Effects of Low and High Frequency in a Novel Device for Passive Inhibitory Avoidance Task That Avoids Bioimpedance Variations

Step-down inhibitory avoidance task has been widely used to evaluate aversive memory, but crucial parameters inherent to traditional devices that may influence the behavior analysis (as stimulus frequency, animal's bioimpedance) are frequently neglected.We developed a new device for step-down inhibitory avoidance task by modifying the shape and distribution of the stainless steel bars in the box floor where the stimuli are applied. The bars are 2 mm wide, with rectangular shape, arranged in pairs at intervals of 1cm from the next pairs. Each pair makes an electrical dipole where the polarity inverts after each pulse. This device also presents a component that acquires and records the exact current received by the animal foot and precisely controls the frequency of stimulus applied during the entire experiment.Different from conventional devices, this new apparatus increases the contact surface with bars and animal's paws, allowing the electric current pass through the animal's paws only, drastically reducing the influence of animal's bioimpedance. The analysis of recorded data showed that the current received by the animal was practically the same as applied, independent of the animal's body composition. Importantly, the aversive memory was observed at specific stimuli intensity and frequency (0.35 or 0.5 mA at 62 and 125 Hz but not at 0.20 mA or 20 Hz). Moreover, with this device it was possible to observe the well-known step-down inhibitory avoidance task memory impairment induced by guanosine.This new device offers a substantial improvement for behavioral analysis in step-down inhibitory avoidance task and allows us to precisely compare data from different animals with distinct body composition
