The role of prenatal posttraumatic stress symptoms among trauma exposed women in predicting postpartum depression

Research suggests that a history of trauma and prenatal posttraumatic stress symptoms (PTSS) are predictive of postpartum depression (PPD). Pregnant women at risk for PPD are often identified through depression symptom measures, while PTSS also may help to identify those at increased risk. Women who do not endorse depressive symptoms, though experience PTSS, may be missed when screening is exclusively based on depressive symptoms. The current study aimed to determine if prenatal PTSS were associated with PPD at 4- and 12-week postpartum in trauma-exposed women. Pregnant women (N = 230) in their third trimester were assessed for depression and PTSS at pregnancy, 4 and 12 weeks postpartum. Traumatic life events were assessed during pregnancy. Hierarchical regression analyses examined predictors of PPD, including history of depression, number of past traumas, and symptoms from the posttraumatic stress disorder (PTSD) Checklist short-form (PCL-6). At 4 and 12 weeks postpartum, history of trauma and depression did not predict depressive symptoms, however, irritability and unwanted intrusive memories of trauma were predictive of increased depressive symptoms. Prenatal irritability and unwanted memories may be predictive of elevated PPD symptoms. Future research should examine whether these symptoms represent increased risk of postpartum depressive symptoms to improve screening, prevention, and treatment efforts

Making levulinic acid and ethyl levulinate economically viable: a worldwide technoeconomic and environmental assessment of possible routes

Ethyl levulinate is a diesel additive that has received special attention recently due to its potential for production in large quantities from inexpensive feedstocks. Several processes have been developed for the conversion of biomass into levulinic acid and ethyl levulinate, and an economic analysis of these routes would indicate the main hindering factors of their commercialization. This Review focuses on filling this gap in current knowledge by gathering data from scientific papers and patents to create a simulation to analyze processes by focusing on the production of ethyl levulinate in nine countries or regions across the globe. The key indicator to analyze the economic feasibility of ethyl levulinate production is a comparison of its minimum selling price to the local wholesale price of diesel on an energy basis. Processes simulated in Brazil, China, and India presented promising results with feedstocks such as sugarcane bagasse and rice residues. Also, the integration of ethyl levulinate production into existing ethanol plants is a factor that may improve process economics. Overall, this Review specifies key factors in economic and environmental performances of the processes to indicate research topics that could achieve high impact on industrial‐scale processes once matured64613639FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP2016/10450-

Predictors of Veterans Affairs Health Service Utilization by Women Veterans during Pregnancy

BACKGROUND: Researchers have examined predictors of Veterans Affairs (VA) service use by women veterans in general, but less is known about predictors of VA service use by pregnant veterans. This study examined characteristics associated with planned and actual VA service use by pregnant veterans. METHODS: This study includes data from 510 pregnant veterans enrolled in the Center for Maternal and Infant Outcomes Research in Translation Study. Women veterans completed phone interviews during their first trimester and at 3 months postpartum. The Center for Maternal and Infant Outcomes Research in Translation surveys assessed medical and mental health conditions, VA health care use, trauma history, and pregnancy complications. We conducted bivariate and multivariable logistic regression models assessing planned and actual use of VA services during pregnancy. RESULTS: Lifetime post-traumatic stress disorder (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.11-2.69) and history of military sexual trauma (OR, 1.85; 95% CI, 1.19-2.87) were significantly associated with planned VA service use in multivariable models. Lifetime diagnoses of anxiety (OR, 1.78; C.I.[1.15-2.75) were associated with an increased likelihood of actual VA use during pregnancy, whereas Hispanic ethnicity (OR, 0.59; 95% CI, 0.36-0.96), younger age (OR, 0.95; 95% CI, 0.91-0.99), and access to private health insurance (OR, 0.55; 95% CI, 0.37-0.84) were associated with a decreased likelihood of actual VA service use during pregnancy. CONCLUSIONS: Results emphasize the association between high-risk mental health characteristics and specific demographic characteristics with VA service use among pregnant veterans. Study findings highlight a continued need for women\u27s health care at the VA, as well as the availability of VA providers knowledgeable about perinatal health issues, and informed community providers regarding women veterans\u27 health

Identifying the substance abuse treatment needs of caregivers involved with child welfare

Parental substance use significantly increases risk of child maltreatment, but is often under-identified by child protective services. This study examined how agency use of standardized substance use assessments and child welfare investigative caseworker education, experience, and caseload affected caseworkers’ identification of parental substance abuse treatment needs. Data are from a national probability sample of permanent, primary caregivers involved with child protective services whose children initially remained at home and whose confidential responses on two validated instruments indicated harmful substance use or dependence. Investigative caseworkers reported use of a formal assessment in over two thirds of cases in which substance use was accurately identified. However, weighted logistic regression indicated that agency provision of standardized assessment instruments was not associated with caseworker identification of caregiver needs. Caseworkers were also less likely to identify substance abuse when their caseloads were high and when caregivers were fathers. Implications for agency practice are discussed
