Estradiol, stress reactivity, and daily affective experiences in trauma-exposed women

Estradiol levels are differentially associated with pulse wave velocity in trauma-exposed premenopausal women with and without PTSD

Arterial stiffness is a well-known risk factor for cardiovascular disease. Although estradiol (E2) is known to be cardioprotective, the available data point to a growing cardiovascular disease risk in women before menopause due to posttraumatic stress disorder (PTSD). The present study aimed to investigate the effects of E2 on arterial compliance in trauma-exposed premenopausal women, with and without a clinical diagnosis of PTSD. We hypothesized that E2 will be differentially associated with pulse wave velocity (PWV) in women with PTSD (PTSD+, n = 45) and without PTSD (PTSD-, n = 47). Estradiol and PWV were measured during two separate study visits. Serum E2 levels were measured via the quantitative sandwich enzyme-linked immunoassay technique (ELISA) and log-transformed due to non-normal distribution. Carotid to femoral applanation tonometry was used to measure PWV. Our analyses revealed an overall weak and nonsignificant correlation between E2 and PWV (r = -0.119, P = 0.350). However, when examining each group, we found a negative association between E2 and PWV in PTSD- (r = -0.466, P = 0.004). In contrast, we found an unexpected positive association between E2 levels and PWV in PTSD+ (r = 0.360, P = 0.037). Furthermore, a multiple linear regression revealed that E2 was predictive of PWV in PTSD- only, even after accounting for the phase of the menstrual cycle, age, body mass index, diastolic blood pressure, and PTSD symptom severity (R2 = 0.670, P = 0.005). Interestingly, we also found lower levels of E2 in PTSD+ than PTSD- (1.4 ± 0.4 vs. 1.6 ± 0.4 pg/mL, P = 0.022). These findings suggest that PTSD may inhibit the protective effects of E2 on arterial compliance in women before menopause.NEW & NOTEWORTHY In trauma-exposed premenopausal women, we found that serum estradiol (E2) was a predictor of pulse wave velocity (PWV) only in the absence of a posttraumatic stress disorder (PTSD) diagnosis, even after accounting for the phase of the menstrual cycle, age, body mass index, diastolic blood pressure, and PTSD symptom severity. Moreover, E2 levels were lower in women with PTSD than in those without PTSD. We collected E2 and PWV during two separate visits and controlled for the menstrual cycle phase in our analyses.

Sex Differences in the Comorbidity between Attention Deficit-Hyperactivity Disorder and Posttraumatic Stress Disorder: A Systematic Literature Review and Meta-Analysis

Objective

Attention Deficit-Hyperactivity Disorder (ADHD) and Posttraumatic Stress Disorder (PTSD) are often comorbid and share a common core of symptoms. However, sex and gender-related factors significantly influence their prevalence, clinical presentation, and diagnosis. Here, we conducted a systematic literature review and meta-analysis to examine sex differences in ADHD/PTSD comorbidity during childhood and adulthood.

Methods

A scoping review of PsycINFO and PubMed yielded 13 eligible studies with complete outcome data. We conducted fixed-effects meta-analyses of the sex-stratified prevalence of ADHD/PTSD using pooled odds ratios (OR) with a 95% confidence interval (CI). Fixed-effects subgroup analyses were performed using age as a subgroup. Effect size heterogeneity was assessed using the I2 index and Cochran's Q test.

Results

In the whole sample (N= 13,585; F= 7005, M= 6580), the diagnosis of ADHD/PTSD was significantly higher in females than in males (OR = 1.32, p = 0.02). Between-study heterogeneity was low-to-moderate and not significant (I2 = 41%; p = 0.06), validating the fixed-effects model. Age-stratified subgroup analyses revealed higher ADHD/PTSD odds in females compared to males only in adult populations (OR=1.41; p = 0.01). Additionally, females were more likely to be diagnosed with both disorders in studies where ADHD was the primary diagnosis (OR = 1.60; p = 0.002), and in studies employing structured clinical interviews as diagnostic tools (OR = 1.46; p = 0.009).

Conclusions

Our study is the first to show that the association between ADHD and PTSD is stronger in females, suggesting that ADHD may increase risk for PTSD in a sex-specific manner.

Long-lasting effects of post-traumatic stress disorder in Yazidi women living in Northern Iraqi camps

The severity of post-traumatic stress disorder and its long-lasting effects among the Yazidi population has not yet been investigated.

Objectives

This study evaluated the impact of PTSD severity and chronicity on physiological and anthropometric parameters in women survivors of the genocide-related events after the so-called Islamic State of Iraq and Syria (ISIS) attack in 2014.

Methods

The diagnosis PTSD was assessed using PTSD Checklist for DSM-5 (PCL-5). Participants were divided into: External control (healthy individuals living outside the camps), Internal control (healthy individuals living in the camps), and PTSD group (individuals diagnosed with PTSD). The PTSD group was subdivided according to chronicity <2 years, 2-5 years, and >5 years and subdivided according to PTSD severity into "Moderate", "Severe" and "Extreme". Systolic blood pressure (SBP), diastolic blood pressure (DBP), blood oxygen saturation (SPO2) and heart rate (HR) were evaluated. Weight, height and waist circumference were measured. Body mass index (BMI) and waist-to-height ratio (WHtR) were calculated.

Results

The PTSD group showed significant increases in SBP, DBP, heart rate, BMI, WC, weight, and WHtR compared to the control groups. SPO2 values decreased in the PTSD group. As the disease progressed, there were further increases in SBP, DBP, heart rate, BMI, WC, WHtR, and weight. Similar increases were observed with the severity of the disease.

Conclusion

Our data indicates that a long-term impact on physiological and anthropometric parameters is present in women diagnosed with PTSD which might be aggravated by the severity and chronicity of the disease.

The role of neurosteroids in posttraumatic stress disorder and alcohol use disorder: A review of 10 years of clinical literature and treatment implications

Rates of alcohol use disorder (AUD) are increasing in men and women and there are high rates of concurrent posttraumatic stress disorder (PTSD) and AUD. AUD and PTSD synergistically increase symptomatology and negatively affect treatment outcomes; however, there are very limited pharmacological treatments for PTSD/AUD. Neurosteroids have been implicated in the underlying neurobiological mechanisms of both PTSD and AUD and may be a target for treatment development. This review details the past ten years of research on pregnenolone, progesterone, allopregnanolone, pregnanolone, estradiol, testosterone and dehydroepiandrosterone/dehydroepiandrosterone-sulfate (DHEA/DHEA-S) in the context of PTSD and AUD, including examination of trauma/alcohol-related variables, such as stress-reactivity. Emerging evidence that exogenous pregnenolone, progesterone, and allopregnanolone may be promising, novel interventions is also discussed. Specific emphasis is placed on examining the application of sex as a biological variable in this body of literature, given that women are more susceptible to both PTSD diagnoses and stress-related alcohol consumption.

Trauma and female reproductive health across the lifecourse: motivating a research agenda for the future of women's health

The aetiology behind many female reproductive disorders is poorly studied and incompletely understood despite the prevalence of such conditions and substantial burden they impose on women's lives. In light of evidence demonstrating a higher incidence of trauma exposure in women with many such disorders, we present a set of interlinked working hypotheses proposing relationships between traumatic events and reproductive and mental health that can define a research agenda to better understand reproductive outcomes from a trauma-informed perspective across the lifecourse. Additionally, we note the potential for racism to act as a traumatic experience, highlight the importance of considering the interaction between mental and reproductive health concerns, and propose several neuroendocrinological mechanisms by which traumatic experiences might increase the risk of adverse health outcomes in these domains. Finally, we emphasize the need for future primary research investigating the proposed pathways between traumatic experiences and adverse female reproductive outcomes.

Duration of exposure to epidural anesthesia at delivery, DNA methylation in umbilical cord blood and their association with offspring asthma in Non-Hispanic Black women

Epidural anesthesia is an effective pain relief modality, widely used for labor analgesia. Childhood asthma is one of the commonest chronic medical illnesses in the USA which places a significant burden on the health-care system. We recently demonstrated a negative association between the duration of epidural anesthesia and the development of childhood asthma; however, the underlying molecular mechanisms still remain unclear. In this study of 127 mother-child pairs comprised of 75 Non-Hispanic Black (NHB) and 52 Non-Hispanic White (NHW) from the Newborn Epigenetic Study, we tested the hypothesis that umbilical cord blood DNA methylation mediates the association between the duration of exposure to epidural anesthesia at delivery and the development of childhood asthma and whether this differed by race/ethnicity. In the mother-child pairs of NHB ancestry, the duration of exposure to epidural anesthesia was associated with a marginally lower risk of asthma (odds ratio = 0.88, 95% confidence interval = 0.76-1.01) for each 1-h increase in exposure to epidural anesthesia. Of the 20 CpGs in the NHB population showing the strongest mediation effect, 50% demonstrated an average mediation proportion of 52%, with directional consistency of direct and indirect effects. These top 20 CpGs mapped to 21 genes enriched for pathways engaged in antigen processing, antigen presentation, protein ubiquitination and regulatory networks related to the Major Histocompatibility Complex (MHC) class I complex and Nuclear Factor Kappa-B (NFkB) complex. Our findings suggest that DNA methylation in immune-related pathways contributes to the effects of the duration of exposure to epidural anesthesia on childhood asthma risk in NHB offspring.

Menstrual Cycle in Trauma-Related Disorders: A Mini-Review

Fluctuations of sex hormones across the menstrual cycle have been linked to exacerbation of symptoms of psychiatric disorders. Women diagnosed with trauma-related disorders such as post-traumatic stress disorder (PTSD) and borderline personality disorder (BPD) have reported worsening of mood symptoms at various phases of their menstrual cycle. There is also considerable overlap between PTSD, BPD, and complex-PTSD (cPTSD) symptoms, suggesting similar biological underpinnings. This mini-review examines the influence of sex hormones and the menstrual cycle on PTSD, BPD, and cPTSD symptoms, and discusses the involvement of the hypothalamic-pituitary-adrenal (HPA) axis. We review literature showing that PTSD and BPD symptoms fluctuate with the menstrual cycle, though the effect of the menstrual cycle phase appears to be inconsistent, warranting future research. Based on the reported phasic vulnerability in individuals with PTSD and BPD, it is plausible to assume that women diagnosed with the newly introduced cPTSD may experience similar difficulties. However, no study to date has addressed this. This review highlights the importance of considering an individual's trauma history as it may influence symptom severity and diagnosis, and the phase of the menstrual cycle at the time of diagnosis. This review also highlights that additional work is needed to clarify the influence of estradiol and progesterone fluctuations on trauma-related symptoms, especially in cPTSD. Continued research on menstrual cycle vulnerability and trauma will lead to better informed management and treatment of PTSD, BPD, and cPTSD.
