Relationship between childhood maltreatment and geriatric depression: the mediator effect of personality traits.

Childhood maltreatment is an important factor associated with adverse mental health outcomes including geriatric depression and the "big five" personality characteristics. The objective of this study was to evaluate a model where personality characteristics mediate the relationship between childhood maltreatment and geriatric depression. In this cross-sectional study, elderly subjects from socioeconomically disadvantaged neighborhoods of Porto Alegre, Brazil (n = 260) completed the Childhood Trauma Questionnaire (CTQ), NEO-Five Factor Inventory (NEO-FFI), and Mini International Neuropsychiatric Interview 5.0 (MINI plus). We used structural equation modeling (SEM) to evaluate the mediation hypothesis. The five personality factors (neuroticism, extraversion, agreeableness, openness, and conscientiousness) were related to childhood maltreatment and depression. Mediation analysis revealed that neuroticism and extraversion are complete mediators, agreeableness and conscientiousness are partial mediators, and openness is not a mediator. These findings support the hypothesis in which childhood maltreatment is associated with geriatric depression and mediated by personality factors. These results suggest that reducing the maladaptive personality trait in elderly people who suffered childhood maltreatment could prevent geriatric depression

Anastrepha anomala Stone was obtained from Parahancornia amapa (Huber) Ducke (Apocynaceae) fruits, and Anastrepha hastata Stone from Cheiloclinium cognatum (Miers.) (Hippocrateaceae) in the State of Amapá, Brazil. Two braconids, Doryctobracon sp. and Opius bellus Gahan, were reared from the latter fruit fly species. This is the first record of P. amapa as a fruit fly host. C. cognatum is the first host known to A. hastata. Both braconids are also the first records of parasitoids for this species.Anastrepha anomala Stone foi obtida de frutos de Parahancornia amapa (Huber) Ducke (Apocynaceae) e Anastrepha hastata Stone de Cheiloclinium cognatum (Miers.)

Centrality dependence of charged particle production at large transverse momentum in Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm{NN}}} = 2.76 TeV

The inclusive transverse momentum ($p_{\rm T}$) distributions of primary charged particles are measured in the pseudo-rapidity range $|\eta|<0.8$ as a function of event centrality in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=2.76$ TeV with ALICE at the LHC. The data are presented in the $p_{\rm T}$ range $0.15<p_{\rm T}<50$ GeV/$c$ for nine centrality intervals from 70-80% to 0-5%. The Pb-Pb spectra are presented in terms of the nuclear modification factor $R_{\rm{AA}}$ using a pp reference spectrum measured at the same collision energy. We observe that the suppression of high-$p_{\rm T}$ particles strongly depends on event centrality. In central collisions (0-5%) the yield is most suppressed with $R_{\rm{AA}}\approx0.13$ at $p_{\rm T}=6$-7 GeV/$c$. Above $p_{\rm T}=7$ GeV/$c$, there is a significant rise in the nuclear modification factor, which reaches $R_{\rm{AA}} \approx0.4$ for $p_{\rm T}>30$ GeV/$c$. In peripheral collisions (70-80%), the suppression is weaker with $R_{\rm{AA}} \approx 0.7$ almost independently of $p_{\rm T}$. The measured nuclear modification factors are compared to other measurements and model calculations.Comment: 17 pages, 4 captioned figures, 2 tables, authors from page 12, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/284
