OBJECTIVE: Dissociative symptoms are both a pathological consequence of exposure to psychological trauma as well as a side effect of N-methyl-d-aspartate (NMDA) receptor antagonist medications; therefore, accurate and valid assessment of these symptoms is important. The psychometric properties of the 23-item Clinician Administered Dissociative States Scale (CADSS) have been characterized in the ketamine and esketamine literatures. Here, we examine its performance in a sample with and without posttraumatic stress disorder (PTSD) and a history of exposure to psychological trauma.
METHODS: Participants with a history of psychological trauma with (N = 148) and without (N = 100) the diagnosis of PTSD and healthy participants without a psychiatric disorder or history of trauma (N = 28) were assessed with the 23-item CADSS and other psychometric and neuropsychological assessments. Analyses were performed to examine internal consistency, convergent and discriminant validity, factor structure, differential performance in populations reported to be more or less likely to report dissociative symptoms (e.g., patients with and without PTSD), and sensitivity to change resulting from exposure to trauma-related sights and sounds.
RESULTS: The 23-item CADSS was found to have high internal consistency (Cronbach\'s alpha 0.91) and a single-factor structure. CADSS total scores in trauma-exposed participants with PTSD were higher than those in trauma-exposed participants without PTSD and non-traumatized non-PTSD participants. Finally, veterans with Iraq combat-related PTSD showed a significant increase in CADSS total score after exposure to combat-related slides and sounds.
CONCLUSIONS: The 23-item CADSS, already validated as a tool to measure dissociation related to administration of NMDA receptor antagonist medication, performs in a reliable and valid manner in the assessment of dissociation in psychologically traumatized participants.

The study aimed to determine differences in sagittal-plane joint biomechanics between athletes with and without knee osteoarthritis (OA) during drop vertical jump 2 years after anterior cruciate ligament reconstruction (ACLR). Forty-one athletes with ACLR completed motion analysis testing during drop vertical jump from 30 cm. Sagittal-plane peak joint angles and moments and joint contributions to total support moment (TSM) were calculated during first landing. Medial compartment knee OA of the reconstructed knee was evaluated using Kellgren-Lawrence scores (ACLR group: Kellgren-Lawrence <2; ACLR-OA group: Kellgren-Lawrence ≥2). The ACLR-OA group (n = 13) had higher hip and lower knee contributions in the surgical limb than the ACLR group and their nonsurgical limb. Further, the ACLR-OA group had higher peak hip extension moment than the ACLR group (P = .024). The ACLR-OA group had significantly lower peak knee extension and ankle plantar flexion moments and TSM (P ≤ .032) than ACLR group. The ACLR-OA group landed with increased hip extension moment, decreased knee extension and ankle plantar flexion moments and TSM, and decreased knee and increased hip contributions to TSM compared with ACLR group. The ACLR-OA group may have adopted movement patterns to decrease knee load and compensated by shifting the load to the hip. Clinicians may incorporate tailored rehabilitation programs that mitigate the decreased knee load to minimize the risk of knee OA after ACLR.

Kyphosis is a condition in which there is a curvature of the spine that causes a bowing of the back, which in turn leads to slouching posture or hunchback. There are several types of Kyphosis, including posttraumatic Kyphosis, which usually occurs in the thoracic region. There are several techniques used for the surgical management of posttraumatic thoracolumbar Kyphosis. We aimed to discuss the surgical treatment of posttraumatic thoracolumbar Kyphosis. We searched for articles included in this review through scientific websites using different keywords. The articles were chosen based on inclusion criteria. The articles included in this review were published between 2006 and 2018. The review was written under titles in the discussion part. The outcome of the surgical management of posttraumatic thoracolumbar Kyphosis depends on the accurate selection of the proper surgical approach.

Posttraumatic headaches are one of the most common and controversial secondary headache types. After a mild traumatic brain, an estimated 11% to 82% of people develop a postconcussion syndrome, which has been controversial for more than 160 years. Headache is estimated as present in 30% to 90% of patients after a mild head injury. Most headaches are tension-type-like or migraine-like. Headaches in civilians, soldiers, athletes, and postcraniotomy are reviewed. The treatments are the same as for the primary headaches. Persistent posttraumatic headaches can continue for many years.

Spontaneous spinal arthrodesis (SSA) is a phenomenon of spontaneous fusion, and SSA is not rare in posttraumatic thoracolumbar kyphosis (PTK). However, few reports have focused on SSA in patients with PTK. The objective of this study was to investigate the prevalence, features, and predictive factors of SSA in patients with PTK.
In this retrospective study, 70 patients with PTK were included. Data on the clinical and radiologic parameters were obtained and evaluated. According to whether there was SSA or not, patients were divided into an SSA group (n = 45) or a non-SSA group (n = 25). A binary logistic regression analysis was used to identify the predictive factors for SSA.
The incidence of SSA in PTK was 64%. Among 45 patients with PTK with SSA, SSA was present as a solid bridging anterior osteophyte along the vertebral bodies in 11 patients, posterior contiguous bony growth through the facet joints bilaterally in 13 patients, bony formation in both anterior and posterior elements in 18 patients, and direct contiguous bony formation from the injured vertebral body to the adjacent one in 3 patients. Patients with longer disease duration, larger local Cobb angle, and anterior wall height loss (AWHL) ratio of injured vertebral body, and less kyphosis flexibility index were significantly more likely to develop SSA. The parameter of AWHL remained significant in binary logistic regression analysis.
SSA in PTK was common, and the SSA sign presented in various patterns, which might have implications for surgical decisions. AWHL was the independent predictor for SSA.

UNASSIGNED: Persons with hemophilia may encounter various traumatic experiences related to their bleeding disorder throughout their lifetime. Little is known about the clinical impact of disease-related trauma on this population.
UNASSIGNED: To explore the prevalence of posttraumatic stress disorder (PTSD) and posttraumatic stress symptoms in adults with hemophilia A and B and characterize the traumatic experiences they report.
UNASSIGNED: An online survey tool collecting data on participant characteristics and a validated questionnaire containing the PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders 5 were distributed via Research Electronic Data Capture to adults with hemophilia A and B during their annual visit to their hemophilia treatment center. Participants were asked about traumatic experiences specific to their hemophilia prior to self-administering the PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders 5 questionnaire.
UNASSIGNED: Survey responses from 178 individuals across 3 hemophilia treatment centers were included in the analysis, representing a 70% response rate. One hundred one (56.7%) participants identified a hemophilia-related traumatic event, and 21 (11.8%) participants met criteria for a provisional diagnosis of PTSD. Multivariable analysis showed higher odds of a positive PTSD screen in participants with noninfectious (odds ratio [OR], 13.89; 95% CI, 2.23-86.62) and infectious comorbidities (OR, 11.18; 95% CI, 1.34-93.45) and in participants with >1 mental health comorbidity (OR, 10.07; 95% CI, 2.39-42.52). On the contrary, age >46 years (OR, 0.6; 95% CI, 0.01-0.62) and higher education (OR, 0.25; 95% CI, 0.07-0.88) reduced odds of PTSD.
UNASSIGNED: Persons with hemophilia are at risk of developing PTSD and posttraumatic stress symptoms. These data support the need for trauma screening, psychosocial services in the bleeding disorders community, and provision of trauma-informed care by providers.

BACKGROUND: Adolescence has emerged as a particularly vulnerable phase during the COVID-19 pandemic, with eating disorders (EDs) representing a prominent psychopathological challenge linked to the restrictions imposed by the pandemic. Emerging evidence suggests that not only individuals with EDs but also their healthy siblings (HS) may experience unique psychological effects in this context. However, the existing literature on this topic remains limited. This study seeks to examine and compare the effects of the pandemic on adolescents and adults, with a specific focus on the impact of containment measures, disruptions in daily routines, and alterations in life trajectories, for both individuals with EDs and their HS.
METHODS: We enrolled 273 individuals, including those diagnosed with EDs and their HS. Among the participants, 120 were under the age of 19. Multiple self-report questionnaires were administered to assess the psychological impact of 1 year of the COVID-19 pandemic. These assessments covered a range of psychological constructs, including posttraumatic symptoms, general psychopathology, and eating-related concerns.
RESULTS: Notably, adolescent patients with EDs demonstrated the highest psychopathological scores within our sample. They were the sole subgroup to surpass clinical cutoffs, exhibiting more pronounced issues concerning eating-related concerns and general psychological well-being. Our findings also shed light on the unique experiences of HS during the pandemic.
CONCLUSIONS: Our findings highlight the specific psychological burden endured by adolescents with EDs throughout the COVID-19 pandemic, emphasizing the vulnerability of this demographic. Moreover, the experiences of HS, often overlooked in the literature, warrant increased attention in future health programs and interventions.

Alexithymia, psychological distress, and posttraumatic stress disorder (PTSD) are highly related constructs. The ongoing debate about the nature and relationship between these constructs is perpetuated by an overreliance on cross-sectional research. We examined the longitudinal interactive relationship between alexithymia, psychological distress, and PTSD. We hypothesised that there is an interactive relationship between the three constructs. Military personnel (N = 1871) completed the Toronto Alexithymia Scale, the Kessler 10 and a PTSD Checklist (PCL-C) at pre-deployment, post-deployment, and at 3-4 years following the post-deployment assessment. We initially tested whether psychological distress is either a moderator or mediator in the relationship between alexithymia and PTSD across the time points. General psychological distress was a partial mediator of total PTSD severity and hyperarousal symptomology at all three time points. Psychological distress fully mediated re-experiencing and avoidance symptomology at all three time points. Our results suggest that those with alexithymia are at longitudinal risk of developing more severe PTSD symptomology and experiencing hyperarousal irrespective of temporal proximity to traumatic exposure. Further, vulnerability to the emergence of re-experiencing and avoidance symptomology for those with alexithymia is increased when one experiences greater distress. Our results show that alexithymia is a persistent risk factor for PTSD symptomology.

BACKGROUND: A dural arteriovenous fistula (dAVF) involving the vertebral artery (VA) is a rare vascular pathology that can result from damage to the VA, most frequently following cervical spine trauma. In most traumatic cases, the dAVF develops and manifests shortly after trauma.
METHODS: A patient was admitted after a fall from the stairs causing neck pain. Computed tomography of the cervical spine revealed a Hangman\'s fracture, and angiography showed a left VA dissection. The patient was treated with a cervical brace and clopidogrel. Three weeks after trauma, the patient was admitted because of bilateral leg ataxia, dizziness, and neck pain. Repeat imaging revealed increased displacement of the cervical fracture and a dAVF from the left VA with retrograde filling of the dAVF from the right VA. Embolization of the dAVF using coils proximally and distally to the dAVF was performed prior to placing a halo brace. At 6 months, all symptoms had disappeared and union of the cervical spine fracture had occurred.
CONCLUSIONS: This case report emphasizes the need for follow-up angiography after traumatic VA injury resulting from cervical spine fracture and underlines important treatment considerations for successful obliteration of a dAVF of the VA.

BACKGROUND: In 2020, Greater New Orleans, Louisiana, was home to 7048 people living with HIV-1083 per 100,000 residents, 2.85 times the US national rate. With Louisiana routinely ranked last in indexes of health equity, violent crime rates in Orleans Parish quintupling national averages, and in-care New Orleans people living with HIV surviving twice the US average of adverse childhood experiences, accessible, trauma-focused, evidence-based interventions (EBIs) for violence-affected people living with HIV are urgently needed.
OBJECTIVE: To meet this need, we adapted Living in the Face of Trauma, a well-established EBI tailored for people living with HIV, into NOLA GEM, a just-in-time adaptive mobile health (mHealth) intervention. This study aimed to culturally tailor and refine the NOLA GEM app and assess its acceptability; feasibility; and preliminary efficacy on care engagement, medication adherence, viral suppression, and mental well-being among in-care people living with HIV in Greater New Orleans.
METHODS: The development of NOLA GEM entailed identifying real-time tailoring variables via a geographic ecological momentary assessment (GEMA) study (n=49; aim 1) and place-based and user-centered tailoring, responsive to the unique cultural contexts of HIV survivorship in New Orleans, via formative interviews (n=12; aim 2). The iOS- and Android-enabled NOLA GEM app leverages twice-daily GEMA prompts to offer just-in-time, in-app recommendations for effective coping skills practice and app-delivered Living in the Face of Trauma session content. For aim 3, the pilot trial will enroll an analytic sample of 60 New Orleans people living with HIV individually randomized to parallel NOLA GEM (intervention) or GEMA-alone (control) arms at a 1:1 allocation for a 21-day period. Acceptability and feasibility will be assessed via enrollment, attrition, active daily use through paradata metrics, and prevalidated usability measures. At the postassessment time point, primary end points will be assessed via a range of well-validated, domain-specific scales. Care engagement and viral suppression will be assessed via past missed appointments and self-reported viral load at 30 and 90 days, respectively, and through well-demonstrated adherence self-efficacy measures.
RESULTS: Aims 1 and 2 have been achieved, NOLA GEM is in Beta, and all aim-3 methods have been reviewed and approved by the institutional review board of Tulane University. Recruitment was launched in July 2023, with a target date for follow-up assessment completion in December 2023.
CONCLUSIONS: By leveraging user-centered development and embracing principles that elevate the lived expertise of New Orleans people living with HIV, mHealth-adapted EBIs can reflect community wisdom on posttraumatic resilience. Sustainable adoption of the NOLA GEM app and a promising early efficacy profile will support the feasibility of a future fully powered clinical trial and potential translation to new underserved settings in service of holistic survivorship and well-being of people living with HIV.
