    The associations between intimate partner violence (IPV) and mental health among adolescents and young adults were compared in the current study. The connections among marriage status, Latino heritage and abusive experiences were also analyzed. 672 women including 282 adolescents between the ages of 14 and 19 and 390 young adults aged 20 or 21 participated in the study. Significant correlations were discovered between anxiety and depression symptoms among adolescents while anxiety and IPV, anxiety and depression, depression and IPV were all significantly correlated among young adults. In addition, IPV and marriage status as well as marriage status and Latina heritage were significantly correlated among young adults. No significant findings came from linear or logistic regressions conducted with the adolescent data but, among young adults, linear regressions with IPV as the dependent variable led to significant relationships between IPV and marital status. In addition, logistic regressions indicated significant links in the young adult data between IPV and depression and anxiety symptoms. IPV during adolescence may be a different phenomenon than adult IPV or mental health symptoms may be latent variables that are reported later in life. Prevention programs for adolescents as well as young adults are encouraged.

    Postpartum Transitions in Adolescent Mothers\u27 Romantic and Maternal Relationships

    Minority adolescent mothers (N = 375) were interviewed during the prepartum (or early postpartum) period and approximately 1 year later (N = 186) regarding their maternal and romantic relationships, depressive symptomatology, and negative life events. Over time, adolescents reported that male partners provided more support than did mothers and that partners\u27 support was equally important to mothers\u27 support. Further, while support from mothers decreased over time, strain increased. Results highlight the importance of considering relationship stability, At Time 2, partner support was negatively associated with depression only among adolescents who retained the same partner (17%). In addition, adolescents who sustained a romantic relationship disruption (38%) reported more negative life events than did those who had not. Implications for research, intervention, and policy are discussed

    Relative sea-level rise around East Antarctica during Oligocene glaciation

    During the middle and late Eocene (∼48-34 Myr ago), the Earth's climate cooled and an ice sheet built up on Antarctica. The stepwise expansion of ice on Antarcticainduced crustal deformation and gravitational perturbations around the continent. Close to the ice sheet, sea level rosedespite an overall reduction in the mass of the ocean caused by the transfer of water to the ice sheet. Here we identify the crustal response to ice-sheet growth by forcing a glacial-hydro isostatic adjustment model with an Antarctic ice-sheet model. We find that the shelf areas around East Antarctica first shoaled as upper mantle material upwelled and a peripheral forebulge developed. The inner shelf subsequently subsided as lithosphere flexure extended outwards from the ice-sheet margins. Consequently the coasts experienced a progressive relative sea-level rise. Our analysis of sediment cores from the vicinity of the Antarctic ice sheet are in agreement with the spatial patterns of relative sea-level change indicated by our simulations. Our results are consistent with the suggestion that near-field processes such as local sea-level change influence the equilibrium state obtained by an icesheet grounding line

    CSF1R inhibitor JNJ-40346527 attenuates microglial proliferation and neurodegeneration in P301S mice

    Neuroinflammation and microglial activation are significant processes in Alzheimer’s disease pathology. Recent genome-wide association studies have highlighted multiple immune-related genes in association with Alzheimer’s disease, and experimental data have demonstrated microglial proliferation as a significant component of the neuropathology. In this study, we tested the efficacy of the selective CSF1R inhibitor JNJ-40346527 (JNJ-527) in the P301S mouse tauopathy model. We first demonstrated the anti-proliferative effects of JNJ-527 on microglia in the ME7 prion model, and its impact on the inflammatory profile, and provided potential CNS biomarkers for clinical investigation with the compound, including pharmacokinetic/pharmacodynamics and efficacy assessment by TSPO autoradiography and CSF proteomics. Then, we showed for the first time that blockade of microglial proliferation and modification of microglial phenotype leads to an attenuation of tau-induced neurodegeneration and results in functional improvement in P301S mice. Overall, this work strongly supports the potential for inhibition of CSF1R as a target for the treatment of Alzheimer’s disease and other tau-mediated neurodegenerative diseases

    Introduction:Plasma biomarkers for Alzheimer’s disease (AD) diagnosis/stratification are a“Holy Grail” of AD research and intensively sought; however, there are no well-established plasmamarkers.Methods:A hypothesis-led plasma biomarker search was conducted in the context of internationalmulticenter studies. The discovery phase measured 53 inflammatory proteins in elderly control (CTL;259), mild cognitive impairment (MCI; 199), and AD (262) subjects from AddNeuroMed.Results:Ten analytes showed significant intergroup differences. Logistic regression identified five(FB, FH, sCR1, MCP-1, eotaxin-1) that, age/APOε4 adjusted, optimally differentiated AD andCTL (AUC: 0.79), and three (sCR1, MCP-1, eotaxin-1) that optimally differentiated AD and MCI(AUC: 0.74). These models replicated in an independent cohort (EMIF; AUC 0.81 and 0.67). Twoanalytes (FB, FH) plus age predicted MCI progression to AD (AUC: 0.71).Discussion:Plasma markers of inflammation and complement dysregulation support diagnosis andoutcome prediction in AD and MCI. Further replication is needed before clinical translatio

    The ATLAS inner detector trigger performance in pp collisions at 13 TeV during LHC Run 2

    Get PDF
    The design and performance of the inner detector trigger for the high level trigger of the ATLAS experiment at the Large Hadron Collider during the 2016-18 data taking period is discussed. In 2016, 2017, and 2018 the ATLAS detector recorded 35.6 fb1^{-1}, 46.9 fb1^{-1}, and 60.6 fb1^{-1} respectively of proton-proton collision data at a centre-of-mass energy of 13 TeV. In order to deal with the very high interaction multiplicities per bunch crossing expected with the 13 TeV collisions the inner detector trigger was redesigned during the long shutdown of the Large Hadron Collider from 2013 until 2015. An overview of these developments is provided and the performance of the tracking in the trigger for the muon, electron, tau and bb-jet signatures is discussed. The high performance of the inner detector trigger with these extreme interaction multiplicities demonstrates how the inner detector tracking continues to lie at the heart of the trigger performance and is essential in enabling the ATLAS physics programme
