Abstract
Epilepsy, a chronic neurological condition characterized by unpredictable seizures, poses considerable challenges, including disability, stigma, and increased mortality. Psychiatric comorbidities are prevalent in 20-30% of epilepsy patients, notably mood or anxiety disorders, psychotic symptoms, and personality disorders. Trauma and childhood adversities are pivotal risk factors for psychopathology, yet the link between Post-Traumatic Stress Disorder (PTSD) and epilepsy remains underexplored. This meta-analysis is aimed to establish updated estimates of PTSD prevalence among individuals with epilepsy. Fifteen studies, comprising 996 epilepsy patients, were included. The overall pooled prevalence of PTSD in epilepsy patients was 18%. Notably, patients with epilepsy exhibited a three-fold increased risk of developing PTSD compared to the general population. Subgroup analysis revealed a higher PTSD prevalence in uncontrolled studies (25%) compared to controlled studies (14%). Additionally, patients with Psychogenic Non-Epileptic Seizures (PNES) demonstrated higher PTSD prevalence than epilepsy patients, with a threefold higher risk in healthy controls compared to PNES controls. While gender prevalence did not significantly affect PTSD occurrence, drug resistant epilepsy did not correlate with PTSD prevalence. Moreover, age of epilepsy onset showed no significant correlation with PTSD prevalence. This meta-analysis underscores the substantial burden of PTSD among epilepsy patients, potentially attributable to the traumatic nature of seizures and the chronic stigma associated with epilepsy. Improved recognition and management of psychiatric conditions, particularly PTSD, are crucial in epilepsy care pathways to enhance patients' quality of life. Further research and comprehensive diagnostic tools are imperative to better understand and address the prevalence of PTSD in epilepsy patients.

Trajectories of post-traumatic stress in sepsis survivors two years after ICU discharge: a secondary analysis of a randomized controlled trial. Crit Care 2024; 28:35. [PMID: 38287438 PMCID: PMC10823628 DOI: 10.1186/s13054-024-04815-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 01/18/2024] [Indexed: 01/31/2024] Open
Abstract
BACKGROUND Post-traumatic stress has been identified as a frequent long-term complication in survivors of critical illnesses after sepsis. Little is known about long-term trajectories of post-traumatic stress and potentially modifiable risk factors following the ICU stay. Study objective was to explore and compare different clinical trajectories of post-traumatic stress symptoms in sepsis survivors up to two years after discharge from ICU. METHODS Data on post-traumatic stress symptoms by means of the Post-traumatic Symptom Scale (PTSS-10) were collected in sepsis survivors at one, six, 12 and 24 months after discharge from ICU. Data on chronic psychiatric diagnoses prior ICU were derived from the primary care provider's health records, and data on intensive care treatment from ICU documentation. Trajectories of post-traumatic symptoms were identified ex post, discriminating patterns of change and k-means clustering. Assignment to the trajectories was predicted in multinomial log-linear models. RESULTS At 24 months, all follow-up measurements of the PTSS-10 were completed in N = 175 patients. Three clusters could be identified regarding clinical trajectories of PTSS levels: stable low symptoms (N = 104 patients [59%]), increasing symptoms (N = 45 patients [26%]), and recovering from symptoms (N = 26 patients [15%]). Patients with initially high post-traumatic symptoms were more likely to show a decrease (OR with 95% CI: 1.1 [1.05, 1.16]). Females (OR = 2.45 [1.11, 5.41]) and patients reporting early traumatic memories of the ICU (OR = 4.04 [1.63, 10]) were at higher risk for increasing PTSS levels. CONCLUSION Post-traumatic stress is a relevant long-term burden for sepsis patients after ICU stay. Identification of three different trajectories within two years after ICU discharge highlights the importance of long-term observation, as a quarter of patients reports few symptoms at discharge yet an increase in symptoms in the two years following. Regular screening of ICU survivors on post-traumatic stress should be considered even in patients with few symptoms and in particular in females and patients reporting traumatic memories of the ICU.

Abstract
Post-traumatic stress disorder (PTSD) is a common mental health disorder, with an incidence of up to 12.5% among primary care patients. Most often, PTSD is detected in combat veterans, victims of terrorist attacks and terror, but it can also be a consequence of traumatic brain injury and medical interventions. Impaired cognitive functioning is a key feature of PTSD, including attention deficits and reduced processing speed, executive dysfunction, and impairments in verbal learning and memory. Cognitive impairments in PTSD are significantly persistent and are largely similar in nature to neuropsychological impairments in neurodegenerative pathology. Possible pathogenetic mechanisms underlying PTSD are the development of neuroinflammation, oxidative stress and decreased production of neurotrophic factors. One of the promising areas of treatment is the use of Cerebrolysin, which has powerful neurotrophic and anti-inflammatory activity.

Cureus 2023; 15:e41562.

Abstract
Transcranial electrical motor evoked potential (TCeMEP) is used to monitor the integrity of intraoperative motor function. Total intravenous anesthesia (TIVA) is the preferred method because its effect on MEP is relatively smaller than volatile anesthetics. However, maintaining the balanced anesthesia in long-time surgery using TIVA is challenging and may sometime cause problems including body movement during microsurgery. Such problems can be avoided by intraoperative anesthesia management using a mixture of propofol and a low concentration of sevoflurane. We recorded TCeMEP under a mixture of propofol and low concentration of sevoflurane anesthesia in three cases of neurosurgery. Anesthesia was induced with a 5.0 µg/mL target-controlled infusion of propofol and 0.6 mg/kg rocuronium. General anesthesia was maintained by propofol and 0.1-0.25 µg/kg/min remifentanil infusion. After the recording of control TCeMEP, sequential inhalation of 0.2 minimum alveolar concentration (MAC) and 0.5 MAC of sevoflurane was performed. The duration of each sevoflurane inhalation was 10 minutes, and the MACs were adjusted by the patient's age. In our cases, the combination of propofol and 0.2 MAC sevoflurane suppressed the amplitude of TCeMEP to 38.0±21.7% (379.8±212.0 µV), but the amplitude was high enough for evaluation of motor function monitoring. On the other hand, the combination of 0.5 MAC sevoflurane greatly decreased the amplitude of TCeMEP to 6.3±6.0% (71.9±66.9 µV) resulting in less than 150 µV, and it was difficult to record the change in TCeMEP amplitude over time. The combination of 0.2 MAC sevoflurane with TIVA might enable TCeMEP monitoring with TIVA.

A proof-of-concept randomized controlled trial of follow-up mental health care for traumatic injury patients following hospital discharge. Injury 2023; 54:1362-1368.

Abstract
INTRODUCTION Traumatic injuries account for a huge burden of disease. Many patients develop persistent mental health problems in the months following hospital discharge. This proof-of-concept trial investigated whether Stepped Care comprising follow-up assessment telephone calls and appropriate referral information would lead to better mental health and functioning in traumatic injury patients. METHODS Patients admitted to the Trauma Service at Royal North Shore Hospital were randomized to either Stepped Care (n = 84) or Treatment as Usual (n = 90). All patients were assessed for anxiety, depression, and posttraumatic stress prior to hospital discharge. Those in Stepped Care received a telephone call at 1-month and 3-months after hospital discharge in which they were administered a brief assessment; patients who reported mental health or pain difficulties were provided with information for local specialists to address their specific problem. All patients were independently assessed by telephone interview 9- months after hospital discharge for posttraumatic stress disorder (PTSD) (primary outcome), as well as for anxiety, depression, disability, and pain. RESULTS There were 58 (73%) patients that could be contacted at either the 1-month or 3-month assessments. Of those contacted, 28 patients (48% of those contacted) were referred for specialist assistance. There were no differences between treatment arms on PTSD symptoms at follow-up [F1,95 = 0.55, p = 0.46]. At the 9-month assessment, patients in the Stepped Care condition reported significantly less anxiety [F1,95 = 5.07, p = 0.03] and disability [F1,95 = 4.37, p = 0.04] relative to those in Treatment as Usual. At 9 months there was no difference between conditions on depression [F1,95 = 1.03, p = 0.31]. There were no differences between conditions on self-reported pain difficulties. CONCLUSIONS This proof-of-concept trial suggests that brief screening assessments of traumatic injury patients following hospital discharge, combined with appropriate referral information, may lead to better functional outcomes. Further research is needed with larger sample sizes and greater verification of referral uptake to validate this finding.

Abstract
Patients with gastrointestinal (GI) complaints report high rates of previous psychological trauma such as physical, emotional abuse and neglect, sexual trauma, and other traumatic experiences. History of trauma is considered a risk factor for the development of disorders of gut-brain interaction, including irritable bowel syndrome. This article discusses key points for providers in understanding how various aspects of trauma can affect patients' physical and mental health and medical interactions, as well as trauma-informed strategies providers can use to increase patient comfort, improve communication, and improve effectiveness of treatment.

Abstract
PURPOSE OF REVIEW Dysfunction of fear memory systems underlie a cluster of clinically important and highly prevalent psychological morbidities seen in perioperative and critical care patients, most archetypally posttraumatic stress disorder (PTSD). Several sedative-hypnotics and analgesics are known to modulate fear systems, and it is theoretically plausible that clinical decisions of the anesthesiologist could impact psychological outcomes. This review aims to provide a focused synthesis of relevant literature from multiple fields of research. RECENT FINDINGS There is evidence in some contexts that unconscious fear memory systems are less sensitive to anesthetics than are conscious memory systems. Opiates may suppress the activation of fear systems and have benefit in the prevention of PTSD following trauma. There is inconsistent evidence that the use of propofol and benzodiazepines for sedation following trauma may potentiate the development of PTSD relative to other drugs. The benefits of ketamine seen in the treatment of major depression are not clearly replicated in PTSD-cluster psychopathologies, and its effects on fear processes are complex. SUMMARY There are multiple theoretical mechanisms by which anesthetic drugs can modulate fear systems and clinically important fear-based psychopathologies. The current state of research provides some evidence to support further hypothesis investigation. However, the absence of effectiveness studies and the inconsistent signals from smaller studies provide insufficient evidence to currently offer firm clinical guidance.

Abstract
BACKGROUND Very little is known regarding the impact of post traumatic stress disorder (PTSD) on the course of multiple sclerosis (MS). OBJECTIVES To explore the impact of pre-existing PTSD on MS relapses, magnetic resonance imaging (MRI) activity, and disability in a large population-based cohort. METHODS Military Veterans with MS and PTSD prior to symptom onset (MSPTSD, n = 96) were identified using the Department of Veterans Affairs MS databases. MSPTSD cases were matched to MS controls without PTSD (n = 95). Number of relapses, number of new T2 lesions and new gadolinium lesions on brain MRI, and neurological disability were abstracted between 2015 and 2019. RESULTS The mean annualized relapse rate was greater in the MSPTSD group versus controls (0.23 vs 0.06, respectively; p < 0.05), as was the annualized mean number of new T2 and gadolinium-enhancing lesions on brain MRI (0.52 vs 0.16 and 0.29 vs 0.08, respectively; p < 0.05). Disability accrual (time to Disability Status Scale 6.0) was more rapid (23.7 vs 29.5 years, p < 0.05) in relapsing MS patients with PTSD. CONCLUSION Patients with MSPTSD have higher disease activity and reach disability endpoints more rapidly than controls. This is the first study to show PTSD as a potentially modifiable risk factor for MS relapses, MRI activity, and disability.

Abstract
To understand how anesthetics with different molecular mechanisms affect consciousness, we explored subjective experiences recalled after responsive and unresponsive sedation induced with equisedative doses of dexmedetomidine, propofol, sevoflurane, and S-ketamine in healthy male participants (N = 140). The anesthetics were administered in experimental setting using target-controlled infusion or vapouriser for one hour. Interviews conducted after anesthetic administration revealed that 46.9% (n = 46) of arousable participants (n = 98) reported experiences, most frequently dreaming or memory incorporation of the setting. Participants receiving dexmedetomidine reported experiences most often while S-ketamine induced the most multimodal experiences. Responsiveness at the end of anesthetic administration did not affect the prevalence or content of reported experiences. These results demonstrate that subjective experiences during responsive and unresponsive sedation are common and anesthetic agents with different molecular mechanisms of action may have different effects on the prevalence and complexity of the experiences, albeit in the present sample the differences between drugs were minute.
