Early cognitive-behavioural therapy for post-traumatic stress symptoms after physical injury. Randomised controlled trial.
ABSTRACT Early single-session psychological interventions, including psychological debriefing following trauma, have not been shown to reduce psychological distress. Longer early psychological interventions have shown some promise.
To examine the efficacy of a four-session cognitive-behavioural intervention following physical injury.
A total of 152 patients attending an accident and emergency department displaying psychological distress following physical injury were randomised 1-3 weeks post-injury to a four-session cognitive-behavioural intervention that started 5-10 weeks after the injury or to no intervention and then followed up for 13 months.
At 13 months, the total Impact of Event Scale score was significantly more reduced in the intervention group (adjusted mean difference=8.4,95% CI 2.4-14.36). Other differences were not statistically significant.
A brief cognitive-behavioural intervention reduces symptoms of post-traumatic stress disorder in individuals with physical injury who display initial distress.

ABSTRACT: This study investigated the effects of β-alanine (BA) ingestion on the behavioral and neuroendocrine response of post-traumatic stress disorder (PTSD) in a murine model. Animals were fed a normal diet with or without (PL) BA supplementation (100 mg kg(-1)) for 30 days. Animals were then exposed to a predator-scent stress (PSS) or a sham (UNEX). Behaviors were evaluated using an elevated plus maze (EPM) and acoustic startle response (ASR) 7 days following exposure to the PSS. Corticosterone concentrations (CS), expression of brain-derived neurotrophic factor (BDNF), and brain carnosine concentrations were analyzed a day later. Animals in PSS+PL spent significantly less time in the open arms and in the number of entries in the EPM than PSS+BA, UNEX+BA, or UNEX+PL. Animals in PSS+BA had comparable scores to UNEX+BA. Anxiety index was higher (p < 0.05) in PSS+PL compared to PSS+BA or animals that were unexposed. ASR and freezing were greater (p < 0.05) in animals exposed to PSS compared to animals unexposed. CS expression was higher (p < 0.05) in animals exposed to PSS compared to unexposed animals. Brain carnosine concentrations in the hippocampus and other brain sections were significantly greater in animals supplemented with BA compared to PL. BDNF expression in the CA1 and DG subregions of the hippocampus was lower (p < 0.05) in animals exposed and fed a normal diet compared to animals exposed and supplemented with BA, or animals unexposed. In conclusion, BA supplementation in rats increased brain carnosine concentrations and resulted in a reduction in PTSD-like behavior, which may be mediated in part by maintaining BDNF expression in the hippocampus.Amino Acids 03/2015; DOI:10.1007/s00726-015-1952-y · 3.65 Impact Factor

ABSTRACT: Currently few evidence based interventions are available for the prevention of PTSD within the first weeks after trauma. Increased risk for PTSD development is associated with dysregulated fear and stress responses prior to and shortly after trauma, as well as with a lack of perceived social support early after trauma. Oxytocin is a potent regulator of these processes. Therefore, we propose that oxytocin may be important in reducing adverse consequences of trauma. The 'BONDS' study is conducted in order to assess the efficacy of an early intervention with intranasal oxytocin for the prevention of PTSD. In this multicenter double-blind randomized placebo-controlled trial we will recruit 220 Emergency Department patients at increased risk of PTSD. Trauma-exposed patients are screened for increased PTSD risk with questionnaires assessing peri-traumatic distress and acute PTSD symptoms within 7 days after trauma. Baseline PTSD symptom severity scores and neuroendocrine and psychophysiological measures will be collected within 10 days after trauma. Participants will be randomized to 7.5 days of intranasal oxytocin (40 IU) or placebo twice a day. Follow-up measurements at 1.5, 3 and 6 months post-trauma are collected to assess PTSD symptom severity (the primary outcome measure). Other measures of symptoms of psychopathology, and neuroendocrine and psychophysiological disorders are secondary outcome measures. We hypothesize that intranasal oxytocin administered early after trauma is an effective pharmacological strategy to prevent PTSD in individuals at increased risk, which is both safe and easily applicable. Interindividual and contextual factors that may influence the effects of oxytocin treatment will be considered in the analysis of the results.Trial registration: Netherlands Trial Registry: NTR3190.BMC Psychiatry 03/2014; 14(1):92.

ABSTRACT: Emergency room nurses were trained to provide a short-term psychological intervention in physically injured patients with Impact of Event Scale (IES) scores > 20. The aims were to study the effects of the psychological intervention relative to usual care (UC). In a randomized controlled trial, psychological distress, daily functioning and the personality traits optimism/pessimism were compared with patients who received the UC. The interventions were provided 1 - 3 months after discharge. The IES scores were significantly reduced in both groups at 3 months (intervention: 41.1 - 28.6, P < 0.001 vs. UC: 35.4 - 26.2, P < 0.001), but not significantly different between groups. Baseline IES score was a significant predictor of IES scores at 3 (β = 0.4, P < 0.05) and 12 months (β = 0.3, P < 0.05), whereas overall daily functioning at 3 months predicted IES scores at 12 months (β = -0.5, P < 0.001). Patients receiving intervention became significantly more optimistic during the year, and had an increase in overall daily functioning from 3 to 12 months (P < 0.001). Patients declining intervention were more pessimistic and had lower daily functioning. Patients who talked with nurses with more training in psychological processing had a larger reduction in IES symptoms at 3 months (β = -0.3, P = 0.081). The nurse-led intervention had a significant effect on optimism and overall daily functioning. Nurses may become a low-cost option to perform short-term psychological interventions with physically injured hospitalized patients.Journal of Clinical Medicine Research 05/2015; 7(5):339-47.
