Research suggests that posttraumatic stress disorder (PTSD) is associated with sexual dysfunction; however, there is a paucity of research examining the relations among trauma exposure, PTSD, and low sexual desire, specifically. Thus, the goal of the present study was to investigate whether women with hypoactive sexual desire disorder (HSDD; n = 132) were more likely to meet criteria for a diagnosis of current or lifetime PTSD relative to women with no sexual desire concerns (n = 137). We also sought to compare the type, frequency, and intensity of PTSD symptoms between the two groups. Finally, we examined whether women in the two groups were exposed to more, or different types of, potentially traumatic events. Compared to women with no sexual health concerns, women with HSDD were more likely to meet criteria for current PTSD, odds ratio (OR) = 5.50, 95% CI [1.18, 25.61]; and lifetime PTSD, OR = 2.78, 95% CI [1.56, 4.94]. Women in the HSDD group also had higher odds of meeting criteria for avoidance (5.10 times) and hyperarousal symptoms (4.48 times) and scored higher on measures of past-month PTSD symptom frequency, d = 0.62, and intensity, d = 0.57. No group differences were observed regarding reexperiencing symptoms, the associated features of PTSD, or type or frequency of exposure to potentially traumatic events. The findings indicate PTSD symptomatology may be a predisposing or perpetuating contributor to low sexual desire, and low sexual desire and PTSD may be related through an alteration in stress adaptability. © 2020 International Society for Traumatic Stress Studies.PURPOSE Studies show health professional students have a high prevalence of depression. Dental students are especially susceptible due to the burden of the highest debt, exposure to bloodborne pathogens and chronic pain frequency. However, few studies on depression among U.S. dental students exist. This study aims to determine (1) the difference in depression prevalence between U.S. dental students, the general population, and medical students; and (2) demographic and lifestyle characteristics associated with depressive symptoms in dental students. METHODS Researchers surveyed dental students in California in 2018 using a 36- item questionnaire. The Patient Health Questionnaire (PHQ-9), a validated diagnostic screening tool, measured depressive symptoms suggesting clinically significant moderate to severe depression. Additionally, participants answered demographic and lifestyle characteristics questions. Data analysis included bivariable chi-square tests and multivariable logistic regression. RESULTS The response rate was 19.1%. The crude depressive symptom prevalence (27.7%) was similar to that of depression in medical students (27.2%) and higher than the U.S. population (7.7%). Bivariable analysis indicated several characteristics significantly associated (P ≤ 0.05) with moderate to severe depressive symptoms in dental students, including experience of injury/pain, financial insecurity, self-reported minority status, perception of meaningful work, and year in school. Multivariable logistic regression modeling estimated 5 well-being categories as significantly associated with higher odds of not having major depressive symptoms. CONCLUSIONS Prevalence of depressive symptoms among California dental students is similar to depression in medical students and higher than the general population. Results suggest a significant proportion of dental students experience moderate to severe depression and require accessible resources. © 2020 American Dental Education Association.One of the applications of graphene in which its scalable production is of utmost importance is the development of polymer composites. Among the techniques used to produce graphene flakes, the liquid phase exfoliation (LPE) of graphite stands out due to its versatility and scalability. However, the solvents suitable for the LPE process are generally toxic and have a high boiling point, making the processing challenging. The use of low boiling point solvents could be convenient for the processing, due to the easiness of their removal. In this study, we propose the use of poly methyl methacrylate (PMMA) as a stabilizing agent for the production of graphene flakes in a low boiling point solvent, i.e., acetone. The graphene dispersions produced in the mixture acetone-PMMA increases the concentration by +175 %, and contain a higher percentage of few-layer graphene flakes ( less then  5 layers) , e.g., +60 %, compared to the dispersions prepared in acetone. The as-produced graphene dispersions are used to develop graphene/acrylonitrile-butadiene-styrene composites. The mechanical properties of the pristine polymer are improved, i.e ., + 22 % in the Young's modulus, by adding 0.01 wt. % of graphene flakes. Moreover, a decrease of ~ 20 % in the oxygen permeability is obtained using 0.1 wt. % of graphene flakes filler, compared to the unloaded matrix. © 2020 WILEY-VCH Verlag GmbH & Co.  https://www.selleckchem.com/products/isa-2011b.html  KGaA, Weinheim.Refugees affected by multiple traumatic stressors are at high risk for developing trauma-related mental disorders, including posttraumatic stress disorder (PTSD), depression, and insomnia, which is sometimes overlooked. The present study examined the effectiveness of narrative exposure therapy (NET) on trauma-related symptoms in a sample of North Korean refugee youth. We focused on sleep patterns in addition to changes in symptom severity for PTSD, depression, and internalizing and externalizing symptoms. North Korean refugee youth (N = 20) with PTSD were assigned to either an NET-based treatment group or a control group, which consisted of treatment as usual (TAU). There were clinically significant reductions in PTSD, depression, and internalizing and externalizing symptoms for the NET group, Hedges' g = 3.6, but not the TAU group. The change in diagnostic status for PTSD was more notable for participants in the NET group compared to the TAU group. Of note, NET also produced a significant improvement in insomnia symptoms and sleep quality, Hedges' g = 2.1. The substantial recovery regarding overall posttraumatic symptoms in the NET group was observed 2 weeks after the end of treatment and remained stable at 6-month follow-up. The results of the present study suggest that NET may be a treatment option for traumatized North Korean refugee youth and may also be effective for the treatment of sleep problems that arise from traumatic experiences. © 2020 The Authors.
