Preterm infants experience intense stress during the perinatal period because they endure painful and intense medical procedures. Repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis during this period may have long-term effects on subsequent cortisol regulation. A premature delivery may also be intensely stressful for the parents, and they may develop symptoms of posttraumatic stress disorder (PTSD). ⋯ Mothers reported their level of PTSD symptoms. The results showed an interaction between perinatal stress and maternal traumatic stress on the diurnal cortisol slope of preterm infants (R(2) = .32). This suggests that the HPA axis of preterm infants exposed to high perinatal stress may be more sensitive to subsequent environmental stress.

A recent study found that combat amputees had a reduced prevalence of posttraumatic stress disorder (PTSD) compared with nonamputees with serious extremity injuries. We hypothesized that an extended period of impaired consciousness or early treatment with morphine could prevent consolidation of traumatic memory and the development of PTSD. To examine this hypothesis, we retrospectively reviewed 258 combat casualty records from the Iraq or Afghanistan conflicts from 2001-2008 in the Expeditionary Medical Encounter Database, including medications and Glasgow Coma Scale (GCS) scores recorded at in-theater facilities within hours of the index injury. ⋯ None of 20 patients (0%) with GCS scores of 12 or lower had PTSD compared to 20% of patients with GCS scores of 12 or greater who did have PTSD. For patients with traumatic brain injury, those treated with intravenous morphine within hours of injury had a significantly lower prevalence of PTSD (6.3%) and mood disorders (15.6%) compared to patients treated with fentanyl only (prevalence of PTSD = 41.2%, prevalence of mood disorder = 47.1%). GCS scores and morphine and fentanyl treatments were not significantly associated with adjustment, anxiety, or substance abuse disorders.

Symptoms of posttraumatic stress disorder (PTSD) and pain are often comorbid among veterans. The purpose of this study was to investigate to what extent symptoms of anxiety, depression, and alcohol use mediated the relationship between PTSD symptoms and pain among 113 treated male Canadian veterans. Measures of PTSD, pain, anxiety symptoms, depression symptoms, and alcohol use were collected as part of the initial assessment. ⋯ The confidence intervals did not include zero and the indirect effect of PTSD on pain through anxiety was .04, CI [.03, .07]. The indirect effect of PTSD on pain through depression was .04, CI [.02, .07]. These findings suggest that PTSD and pain symptoms among veterans may be related through the underlying symptoms of anxiety and depression, thus emphasizing the importance of targeting anxiety and depression symptoms when treating comorbid PTSD and pain patients.

We examined bereaved children's and surviving caregivers' psychological responses following the death of the other caregiver as a function of the stated cause of death. Participants included 63 parentally bereaved children and 38 surviving caregivers who were assessed using self-report instruments and in-person interviews. Surviving caregivers reported the causes of death as resulting from sudden natural death (34.9%), illness (33.3%), accident (17.5%), and suicide (14.3%). ⋯ In contrast, surviving caregivers did not differ in their levels of maladaptive grief and PTSS as a function of the cause of death; however, caregivers bereaved by sudden natural death reported higher levels of depression than those bereaved by prolonged illness (d = 1.36). Limited sample size prevented analysis of outcomes among those bereaved by suicide or accident. These findings suggest that anticipated deaths may contain etiologic risk factors for maladaptive grief and PTSS in children.

Multiple deployments are common among military personnel who served in Operation Enduring Freedom and Operation Iraqi Freedom and are associated with greater posttraumatic stress symptoms (PTSS). Homefront stressors (i.e., family, occupational problems) resulting from deployments may increase the risk of PTSS. Moreover, with multiple deployments, a new deployment may occur while still experiencing homefront stressors from previous tours. ⋯ Homefront stressors reported at Wave 1 (β = .154, p = .015) and Wave 2 (β = .214, p = .002) were both significantly predictive of PTSS at postdeployment, even after adjusting for warzone stressors, predeployment PTSS, and other variables. A pattern of chronic homefront stressors (i.e., homefront stressors at pre- and postdeployment) was associated with higher levels of PTSS at postdeployment (β = .220, p = .002). Service members with multiple deployments are at greater risk for PTSS if deployed with homefront stressors from previous tours and/or face these stressors at postdeployment.
