Factors influencing the suicide intervention skills of emergency medical services providers

Background: Lithuania currently has the highest suicide rate in Europe and the fifth highest worldwide. Aims: To identify the factors that influence the suicide intervention skills of emergency medical services (EMS) providers (doctors, nurses, paramedics). Method: Two hundred and sixty-eight EMS providers participated in the research. The EMS providers were surveyed both prior to their training in suicide intervention and six months later. The questionnaire used for the survey assessed their socio-demographic characteristics, suicide intervention skills, attitudes towards suicide prevention, general mental health, strategies for coping with stress, and likelihood of burnout. Results: Better suicide intervention skills were more prevalent among EMS providers with a higher level of education, heavier workload, more positive attitudes towards suicide prevention, better methods of coping with stress, and those of a younger age. Six months after the non-continuous training in suicide intervention, the providers’ ability to assess suicide risk factors had improved, although there was no change in their suicide intervention skills. Conclusions: In order to improve the suicide intervention skills of EMS providers, particular attention should be paid to attitudes towards suicide prevention, skills for coping with stress, and continuous training in suicide intervention.

Lateral bias in visual working memory

The present study aimed to evaluate functional cerebral asymmetries of visual working memory (VWM) in relation to language lateralization. The bilateral change detection paradigm with capital letters as stimuli and the translingual lexical decision task were used to assess VWM and language asymmetry, respectively, in a sample of 99 younger healthy participants (59 women). Participant attention was cued towards right or left visual half-field. For the VWM task, men and women were more accurate and faster when stimuli were presented in the right visual half-field compared to the left visual half-field. As expected, a significant right visual half-field advantage was demonstrated in the lexical decision task in performance accuracy (but not response time). The results also revealed no relationship between lateralization in VWM and lexical decision. VWM performance accuracy decreased significantly with increasing asymmetry. This relationship was significant for women, but not men. Taken together, the present study demonstrates that the lateral bias in visual working memory is independent from language lateralization, and less lateralized individuals perform better than individuals with larger asymmetries in both visual half-field tasks

Amygdala reactivity to negative stimuli is influenced by oral contraceptive use

The amygdala is a highly interconnected region of the brain that is critically important to emotional processing and affective networks. Previous studies have shown that the response of the amygdala to emotionally arousing stimuli can be modulated by sex hormones. Because oral contraceptive pills dramatically lower circulating sex hormone levels with potent analogs of those hormones, we performed a functional magnetic resonance imaging experiment to measure amygdala reactivity in response to emotional stimuli in women using oral contraceptives, and compared their amygdala reactivity with that of naturally cycling women. Here, we show that women who use oral contraceptive pills have significantly decreased bilateral amygdala reactivity in response to negatively valenced, emotionally arousing stimuli compared with naturally cycling women. We suggest that by modulating amygdala reactivity, oral contraceptive pills may influence behaviors that have previously been shown to be amygdala dependent—in particular, emotional memory
