EV0622 E-PosterTravma ve StresSistematik derleme ve meta-analiz # Post-traumatic stress disorder in military personnel and veterans with blast-related traumatic brain injury: a systematic review of prevalence, symptom severity, and neurobiology PHYSICAL ACTIVITY, WELLNESS AND RECOVERY AMONG POPULATIONS IN INCARCERATION: A SYSTEMATIC REVIEW Sunan: Emily Jiang Ülke: Canada Kurum: McMaster University, Michael G. DeGroote School of Medicine The prevalence and symptom severity of post-traumatic stress disorder in military personnel and veterans with blast-related traumatic brain injury are significantly higher than in those without traumatic brain injury and are associated with a widespread neural signature. The image file for this record does not match the title on physical activity in conditions of confinement provided in the congress system; instead, it shows a poster examining post-traumatic stress disorder (PTSD) in military personnel and veterans (MP-V) with blast-related traumatic brain injury (B-TBI). This summary is based on the poster’s actual content. The aim was to determine the pooled prevalence, symptom severity, and neurobiological correlates of PTSD in MP-V with B-TBI. The review was conducted according to the PRISMA 2020 guidelines, and five databases were searched. Screening, data extraction, and quality assessment were performed by two independent researchers using Joanna Briggs Institute (JBI) checklists, and qualitative and meta-analytic synthesis, subgroup analysis, and meta-regression were conducted. Veteran samples were the most represented among the cohorts included in the meta-analysis; PTSD ascertainment was evenly divided between symptom screening and clinical diagnosis, mean ages ranged from 25 to 40 years, and sample sizes were generally small. Across forty-six studies, the pooled prevalence of PTSD was 48.6% (95% confidence interval 42.4–54.8) in the exposed groups and 22.4% (95% CI 16.5–29.7) in MP-V without TBI. Confidence intervals overlapped across exposed subgroups, and heterogeneity was substantial (I2=99%). Groups with TBI or blast exposure showed greater symptom severity than unexposed military controls (Hedges’ g=1.34; 95% CI 0.91–1.75; Z=6.12; p<0.001), representing a large effect size; no significant difference was found between the B-TBI and TBI groups (g=0.20; 95% CI −0.03 to 0.43). Among the neurobiological domains, white matter integrity was the most extensively studied, with 18 studies reporting reduced fractional anisotropy in the corpus callosum and long association tracts in relation to PTSD severity. Structural imaging identified cortical and hippocampal volume loss, metabolic studies identified cerebellar and medial temporal hypometabolism, and functional studies identified resting-state amygdala–prefrontal dysconnectivity and amygdala hyperactivation during fear processing. Additional findings included endocrine dysfunction, altered electrophysiology, elevated exosomal tau and amyloid-beta 42, and elevated IL-6. In conclusion, the findings emphasize the need for PTSD screening to facilitate early diagnosis in MP-V with B-TBI, integration of mental health treatment into TBI rehabilitation programs, and long-term follow-up.
