Background: The aim of the present study was to evaluate serum nitric oxide (NO) and C reactive protein (CRP) concentration in veterans with and without PTSD. Furthermore, we aimed to assess whether there is a correlation between serum NO and CRP concentrations in tested groups.
Subjects And Methods: Cross-sectional study included 90 male individuals, with and without experience of direct war combat, divided into three equal groups (n=30): group 1- included war veterans with PTSD, group 2 - included war veterans without PTSD, and control group - 30 apparently healthy volunteers, without experience of direct war combat. The diagnosis of PTSD was assessed according to the guidelines in the 10 revision of the International Classification of Diseases (ICD-10). High-sensitivity CRP was determined by immunonephelometry. The serum NO level was determined by classic colorimetrical Griess reaction.
Results: Serum CRP concentration in veterans with (3.54±1.19 mg/L) and without PTSD (3.24±2.04 mg/L), was significantly higher (p<0.05) compared to control group (1.26±1.06 mg/L). Serum NO concentration in veterans with (7.64±4.43 μmol/L) and without PTSD (7.12±2.60 μmol/L) was significantly lower (p<0.05) compared to control group (11.26±7.01 μmol/L). Statistically significant correlation between serum NO and CRP concentration was determined in veterans without PTSD (r=-0.473; p<0.01). No correlation was observed between serum NO and CRP concentration in veterans with PTSD (r=0.118; p=0.534) and in control group (r=-0.067; p=0.727).
Conclusion: The present study has showed significant increase of serum CRP and significant decrease of serum NO concentrations in veterans with and without PTSD. Furthermore, statistically significant negative correlation between serum NO and CRP concentration was determined only in veterans without PTSD. Obtained results indicate that the complex mechanism of the pathogenesis of PTSD requires further research.

Background: Although many studies have shown that traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD) regardless of their severity, are associated with a significantly increased risk of all-cause dementia, the specific pathophysiological mechanisms that underlie these associations remain poorly understood, resulting in discordance findings among different studies and contradictory claims in the current literature. In this study we investigated the effect of TBI and PTSD on the level of amyloid, tau, as well as markers of small vessel health including white matter hyperintensity and perivascular spaces and consequently assessed their effect on the cognitive function in order to understand the pathways through which TBI and PTSD may result in dementia.
Method: The participants in this study were MCI cases drawn from the ADNI-DOD (n=58).

Introduction: Trauma-focused evidence-based psychotherapy (EBP) is the recommended treatment for post-traumatic stress disorder (PTSD). During and after the COVID-19 pandemic, veterans began to initiate general mental health services delivered via video telehealth at high rates. Our goal in the current project was to describe the percentage as well as the demographic, military, and clinical characteristics of veterans receiving PTSD EBPs via video telehealth versus in-person.

Background: The X-chromosome remains largely unexplored in Alzheimer's disease (AD). To address this gap, we performed the first large-scale X chromosome-wide association study (XWAS) of AD.
Method: The study overview is shown in Figure 1A.

Researchers have begun to explore factors that might promote better adjustment following exposure to traumatic events, including the extent to which individuals have a strong sense of meaning in their lives. Given that studies have shown the potential benefits of cultivating meaning in alleviating posttraumatic stress reactions, it is important to pinpoint specific aspects of meaning that may better inform individualized trauma-focused treatments. One aspect of meaning that may be particularly relevant to trauma survivors is reflected in perceptions of purpose in life.
