Abstract
Wearable cardioverter defibrillators (WCDs) are external devices capable of continuous cardiac rhythm monitoring as well as automatic detection and defibrillation of potentially life-threatening arrhythmias such as ventricular tachycardia (VT) and ventricular fibrillation (VF). They are an alternative approach for patients when an implantable cardioverter defibrillator (ICD) is not appropriate. Although treatment with ICD is considered highly effective for the primary and secondary prevention of sudden cardiac death (SCD) in high-risk patients susceptible to VT and VF, patients may still experience psychological difficulties such as fear of shock, avoidance of normal behaviors and reduced quality of life. One of these phenomena is phantom shock (PS), which is defined as a perception of having received a shock with no evidence of recorded defibrillation upon device interrogation. While PS has been reported in the ICD literature, to the best of our knowledge, we present the first known case of WCD-related PS. We also present a review of the current literature to explore the prevalence of PS, the factors associated with its pathogenesis and interventional studies aimed at reducing its occurrence. We highlight this case because PS is considered a phenomenon that few recognize, which should be discriminated from real device shocks before clinicians initiate treatment, device reprogramming or device discontinuation. We describe the psychosocial factors associated with PS to emphasize the importance of managing any associated psychiatric disorders and psychosocial factors both before and after initiation of device treatment.

Abstract
BACKGROUND Cardiac surgery can be traumatic and stressful, and as a result many people experience psychological difficulties following treatment. AIM To assess the level of post-traumatic stress disorder (PTSD) 1 month after coronary artery bypass graft (CABG) surgery among Jordanian patients, and to examine the predictors of PTSD after 1 month. METHOD A descriptive survey design was used. FINDINGS 149 patients participated in the study. Their mean age was 59 years (SD=10.2) and most were male (87%) and married (93%). Some 44% of patients had PTSD. Length of stay in hospital (c² (1)=6.598, P<0.05), and age (c² (1)=4.920, P<0.05), predicted the occurrence of PTSD after 1 month. CONCLUSIONS Nurses, who are usually in the frontline with patients, should consider using a robust tool and clinical interview to assess and evaluate the presence and the risks of PTSD to promote early detection and optimal management. Follow-up studies after 6 and 12 months would be beneficial.

J Behav Ther Exp Psychiatry 2020; 67:101480. [PMID: 31122650 DOI: 10.1016/j.jbtep.2019.101480] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Revised: 04/26/2019] [Accepted: 04/30/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND AND OBJECTIVES Researchers have conceived of post-traumatic stress disorder (PTSD) as a disorder of memory, and proposed that blocking the impact of stress-related noradrenaline release in the aftermath of trauma may be a way of preventing the 'over-consolidation' of trauma-related memories. Experimental research in humans has been limited by typically focusing on declarative memory for emotional stories, and has mainly given propranolol before learning. In contrast, the clinical studies that we comprehensively review are hampered by practical challenges, such as reliably administering propranolol in a time window sufficiently close to the traumatic event. In this study, we aimed to assess the impact of both pre- and post-learning propranolol on emotional and declarative memory for an emotional scene, using the 'trauma film paradigm'. METHODS To control for drug and timing effects, participants received a pill (40 mg propranolol or placebo) both 60 min before and within 5 min after viewing a 12 min, emotionally arousing trauma film, and were assigned to one of the three conditions: propranolol-placebo (n = 25), placebo-propranolol (n = 25), or placebo-placebo (n = 25). We assessed participants' immediate emotional responses to the scene, as well as delayed impact (intrusions, Impact of Events Scale) and declarative memory. RESULTS Using Bayesian informative hypothesis testing, we found that pre-learning propranolol reduced the initial emotional impact of the 'trauma film'. However, we did not find strong evidence for an impact of pre- or post-learning propranolol on later consequences of having watched the emotional film (intrusions, Impact of Events, or tests of declarative memory). Exploratorily restricting analyses to women, we did find evidence suggesting that pre-encoding propranolol could reduce the rate of intrusions and self-reported negative impact of the emotional scene one week later. LIMITATIONS Floor effects in the delayed impact of the emotional scene could preclude observing differences as a function of propranolol, and propranolol dosage may need to be increased. CONCLUSIONS An impact of propranolol on encoding could raise difficulties in interpretation when only pre-encoding propranolol is used to make inferences about consolidation. We discuss the challenges of elucidating the mechanistic underpinnings of propranolol's reported effects on memory.

Abstract
OBJECTIVE Medical events such as myocardial infarction and cancer diagnosis can induce symptoms of posttraumatic stress disorder (PTSD). The optimal treatment of PTSD symptoms in this context is unknown. METHODS A literature search of 6 biomedical electronic databases was conducted from database inception to November 2018. Studies were eligible if they used a randomized design and evaluated the effect of treatments on medical event-induced PTSD symptoms in adults. A random effects model was used to pool data when two or more comparable studies were available. RESULTS Six trials met full inclusion criteria. Studies ranged in size from 21 to 81 patients, and included patients with PTSD induced by cardiac events, cancer, HIV, multiple sclerosis, and stem cell transplantation. All trials assessed psychological interventions. Two trials comparing a form of exposure-based cognitive behavioral therapy (CBT) with assessment-only control found that CBT resulted in lower PTSD symptoms [Hedges's g = -0.47, (95% CI -0.82 - -0.12), p = .009]. A third trial compared imaginal exposure (another form of exposure-based CBT) with an attention control and found a trend toward reduced PTSD symptoms. Three trials compared eye movement desensitization and reprocessing (EMDR) with active psychological treatments (imaginal exposure, conventional CBT, and relaxation therapy), and found that EMDR was more effective. CONCLUSION CBT and EMDR may be promising approaches to reducing PTSD symptoms due to medical events. However, additional trials are needed in this patient population.

Abstract
We examined whether beta blocker administration in the emergency department (ED) during evaluation for suspected acute coronary syndrome (ACS) was associated with posttraumatic stress disorder (PTSD) symptoms 1-month later. Participants (N = 350) were enrolled in the Reactions to Acute Care and Hospitalization (REACH) study, an ongoing observational cohort study of ED predictors of medical and psychological outcomes after evaluation for suspected ACS. Beta blockade during evaluation in the ED was extracted from medical records, and PTSD symptoms in response to the experience of suspected ACS were assessed 1-month later via telephone. Beta blockade in the ED was associated with lower PTSD symptoms 1-month later, b = -2.80, β = -.09, p = .045, after adjustment for demographics, preexisting psychological and medical covariates, and participants' distress during ED evaluation. Despite small effects, findings suggest that beta blockade during ED evaluation for suspected ACS-a time period relevant to fear consolidation of the memory of this potentially life-threatening event-may have protective effects for later psychological health.

Abstract
INTRODUCTION Depressive symptoms occur in approximately half of trauma patients, negatively impacting on functional outcome and quality of life following severe head injury. Pontine noradrenaline has been shown to increase upon trauma and associated β-adrenergic receptor activation appears to consolidate memory formation of traumatic events. Blocking adrenergic activity reduces physiological stress responses during recall of traumatic memories and impairs memory, implying a potential therapeutic role of β-blockers. This study examines the effect of pre-admission β-blockade on post-traumatic depression. METHODS All adult trauma patients (≥18 years) with severe, isolated traumatic brain injury (intracranial Abbreviated Injury Scale score (AIS) ≥3 and extracranial AIS <3) were recruited from the trauma registry of an urban university hospital between 2007 and 2011. Exclusion criteria were in-hospital deaths and prescription of antidepressants up to one year prior to admission. Pre- and post-admission β-blocker and antidepressant therapy data was requested from the national drugs registry. Post-traumatic depression was defined as the prescription of antidepressants within one year of trauma. Patients with and without pre-admission β-blockers were matched 1:1 by age, gender, Glasgow Coma Scale, Injury Severity Score and head AIS. Analysis was carried out using McNemar's and Student's t-test for categorical and continuous data, respectively. RESULTS A total of 545 patients met the study criteria. Of these, 15% (n=80) were prescribed β-blockers. After propensity matching, 80 matched pairs were analyzed. 33% (n=26) of non β-blocked patients developed post-traumatic depression, compared to only 18% (n=14) in the β-blocked group (p=0.04). There were no significant differences in ICU (mean days: 5.8 (SD 10.5) vs. 5.6 (SD 7.2), p=0.85) or hospital length of stay (mean days: 21 (SD 21) vs. 21 (SD 20), p=0.94) between cohorts. CONCLUSION β-blockade appears to act prophylactically and significantly reduces the risk of post-traumatic depression in patients suffering from isolated severe traumatic brain injuries. Further prospective randomized studies are warranted to validate this finding.

Abstract
Chronic pain patients often have psychiatric disorders that negatively influence their responses to treatment. Also, many of them have dysfunctional beliefs and coping strategies, even if they do not meet DSM-5 criteria for a psychiatric disorder. Physiatrists should have a low threshold for referring both groups of patients for mental health services. This article describes psychiatric disorders that are highly prevalent among pain patients and also describes psychological processes that contribute to poor coping by the patients. Finally, it discusses factors that a physiatrist should consider in deciding whether to refer patients to psychiatrists versus psychologists.

Abstract
BACKGROUND Traumatic memories have been resilient to therapeutic approaches targeting their permanent attenuation. One of the potentially promising pharmacological strategies under investigation is the search for safe reconsolidation blockers. However, preclinical studies focusing on this matter have scarcely addressed abnormal aversive memories and related outcomes. METHODS By mimicking the enhanced noradrenergic activity reported after traumatic events in humans, here we sought to generate a suitable condition to establish whether some clinically approved drugs able to disrupt the reconsolidation of conditioned fear memories in rodents would still be effective. RESULTS We report that the α2-adrenoceptor antagonist yohimbine was able to induce an inability to restrict behavioral (fear) and cardiovascular (increased systolic blood pressure) responses to the paired context when administered immediately after acquisition, but not 6h later, indicating the formation of a generalized fear memory, which endured for over 29 days and was less susceptible to suppression by extinction. It was also resistant to reconsolidation disruption by the α2-adrenoceptor agonist clonidine or cannabidiol, the major non-psychotomimetic component of Cannabis sativa. Since signaling at N-methyl-D-aspartate (NMDA) receptors is important for memory labilization and because a dysfunctional memory may be less labile than is necessary to trigger reconsolidation on its brief retrieval and reactivation, we then investigated and demonstrated that pre-retrieval administration of the partial NMDA agonist D-cycloserine allowed the disrupting effects of clonidine and cannabidiol on reconsolidation. CONCLUSIONS These findings highlight the effectiveness of a dual-step pharmacological intervention to mitigate an aberrant and enduring aversive memory similar to that underlying the post-traumatic stress disorder.

Abstract
The relationship and interactions between stress hormones and post-traumatic stress disorder (PTSD) are well established from both animal and human research studies. This interaction is especially important in the post-operative phase of cardiac surgery where the development of PTSD symptoms will result in increased morbidity and mortality and prolong length of stay for critically ill cardiac surgery patients. Cardiopulmonary bypass itself will independently result in massive inflammation response and release of stress hormones in the perioperative period. Glucocorticoid may reduce this response and result in reduction of PTSD symptom clusters and therefore improve health outcome. In this review, we plan to conduct a systemic review and analysis of the literatures on this topic.
