AbstractThis study intend to compare the long-term psychological impact (depression, post-traumatic stress disorder) on both partners between patients that underwent uterine artery embolization (UAE) for post-partum hemorrhage (PPH) and uneventful deliveries. Women who experienced severe PPH treated by UAE in our institution between 2003 and 2013 were identified in our obstetrical database. These cases were matched to controls with uneventful deliveries. Matching criteria were maternal age, parity, ethnicity, year of delivery, birthweight, gestational age and mode of delivery. Patients and their partners completed validated questionnaires measuring post-traumatic stress (TSQ), as well as depression symptoms (MINI). A total of 63 cases of PPH and 189 matched controls (1:3) participated in a study exploring gynecological and obstetrical outcomes. With a mean of 8 years post-index delivery, patients after PPH showed increased risk of depression (p = 0.015) and post-traumatic stress disorder (22.2% versus 4.8%, p < 0.005) compared to controls. PPH remains strongly associated with post-traumatic stress disorder, even after adjustment for depression (adjusted odds ratio 5.1; 95% confidence intervals 1.5–17.5). Similarly, partners of patients with PPH showed a propensity to depression (p = 0.029) and post-traumatic stress disorder (11.5% versus 1.5%, p = 0.019). In conclusion, both women and their partners are at increased risk of long-term psychological adverse outcomes after PPH. Couples may benefit from psychological support.

Background: We recently discovered autism/intellectual disability somatic mutations in postmortem brains, presenting higher frequency in Alzheimer’s disease subjects, compared with the controls. We further revealed high impact cytoskeletal gene mutations, coupled with potential cytoskeleton-targeted repair mechanisms. Objective: The current study was aimed at further discerning if somatic mutations in brain diseases are presented only in the most affected tissue (the brain), or if blood samples phenocopy the brain, toward potential diagnostics. Methods: Variant calling analyses on an RNA-seq database including peripheral blood samples from 85 soldiers (58 controls and 27 with symptoms of post-traumatic stress disorder, PTSD) was performed. Results: High (e.g., protein truncating) as well as moderate impact (e.g., single amino acid change) germline and putative somatic mutations in thousands of genes were found. Further crossing the mutated genes with autism, intellectual disability, cytoskeleton, inflammation, and DNA repair databases, identified the highest number of cytoskeletal-mutated genes (187 high and 442 moderate impact). Most of the mutated genes were shared and only when crossed with the inflammation database, more putative high impact mutated genes specific to the PTSD-symptom cohorts versus the controls (14 versus 13) were revealed, highlighting tumor necrosis factor specifically in the PTSD-symptom cohorts. Conclusion: With microtubules and neuro-immune interactions playing essential roles in brain neuroprotection and Alzheimer-related neurodegeneration, the current mutation discoveries contribute to mechanistic understanding of PTSD and brain protection, as well as provide future diagnostics toward personalized military deployment strategies and drug design.

Aim. To study the changes in levels of biogenic amines-neurotransmitters in the brain at experimental post-traumatic stress disorder development in rats. Methods. Post-traumatic stress disorder was modeled by keeping 48 outbred male rats in under constant and inescapable strong unconditioned stimulus. The control group included 16 intact animals, not exposed to stress influences. The levels of 3,4-dihydroxyphenylalanine, dopamine, norepinephrine, epinephrine and gamma-aminobutyric acid were determined by fluorometric methods. Behavioral activity of animals was evaluated on the day 3, 7, 10 and 14 by «open field» and «elevated plus maze» actinographs. Results. When comparing the concentrations of studied neurotransmitters in the brain of control animals with experimental groups, reflecting the development of post-traumatic stress disorder at the time, adrenaline and 3,4-dihydroxyphenylalanine levels were increased on the third day, level of norepinephrine was reduced on the seventh day, 3,4-dihydroxyphenylalanine, dopamine, norepinephrine levels were elevaled, gamma-aminobutyric acid level was reduced on the tenth day, gamma-aminobutyric acid level was increased on the fourteenth day after the stress. Conclusion. According to the results of the correlation analysis, the largest contribution to the development of behavioral disorders are made by altered brain level of gamma-aminobutyric acid at the time of post-traumatic stress disorder formation (tenth and fourteenth day). At the earlier stages (third and seventh day), the relationship of rats behavioral activity and altered 3,4-dihydroxyphenylalanine and norepinephrine brain levels was shown.
