    Objective: Borderline personality disorder (BPD) is a devastating condition that causes intense disruption of patients' lives and relationships. Proper understanding of BPD neurobiology could help provide the basis for earlier and effective interventions. As neuroimaging studies of patients with BPD are still scarce, volumetric and geometric features of the cortical structure were assessed to ascertain whether structural cortical alterations are present in BPD patients. Methods: Twenty-five female outpatients with BPD underwent psychiatric evaluation (SCID-I and II) and a 1.5 T magnetic resonance imaging (MRI) brain scan. The control group comprised 25 healthy age-matched females. Images were processed with the FreeSurfer package, which allows analysis of cortical morphology with more detailed descriptions of volumetric and geometric features of cortical structure. Results: Compared with controls, BPD patients exhibited significant cortical abnormalities in the fronto-limbic and paralimbic regions of both hemispheres. Conclusion: Significant morphologic abnormalities were observed in patients with BPD on comparison with a healthy control group through a multimodal approach. This study highlights the involvement of regions associated with mood regulation, impulsivity, and social behavior in BPD patients and presents a new approach for further investigation through a method of structural analysis based on distinct and simultaneous volumetric and geometric parameters.Universidade Federal de SĂŁo Paulo (UNIFESP) Department of Psychiatry Interdisciplinary Laboratory of Clinical NeurosciencesUniversidade Federal do ABC Center of Mathematics, Computation and CognitionUniversidade Federal de SĂŁo Paulo (UNIFESP) Department of Diagnostic RadiologyUniversidade Federal de SĂŁo Paulo (UNIFESP) Department of Psychiatry Outpatient Clinic for Personality Disorders (AMBORDER)UNIFESP, Department of Psychiatry Interdisciplinary Laboratory of Clinical NeurosciencesUNIFESP, Department of Diagnostic RadiologyUNIFESP, Department of Psychiatry Outpatient Clinic for Personality Disorders (AMBORDER)SciEL

    Characterization of Dengue Virus Type 2: New Insights on the 2010 Brazilian Epidemic

    Dengue viruses (DENV) serotypes 1, 2, and 3 have been causing yearly outbreaks in Brazil. In this study, we report the re-introduction of DENV2 in the coast of SĂŁo Paulo State. Partial envelope viral genes were sequenced from eighteen patients with dengue fever during the 2010 epidemic. Phylogenetic analysis showed this strain belongs to the American/Asian genotype and was closely related to the virus that circulated in Rio de Janeiro in 2007 and 2008. The phylogeny also showed no clustering by clinical presentation, suggesting that the disease severity could not be explained by distinct variants or genotypes. The time of the most recent common ancestor of American/Asian genotype and the SĂŁo Paulo and Rio de Janeiro (SP/RJ) monophyletic cluster was estimated to be around 40 and 10 years, respectively. Since this virus was first identified in Brazil in 2007, we suggest that it was already circulating in the country before causing the first documented outbreak. This is the first description of the 2010 outbreak in the State of SĂŁo Paulo, Brazil, and should contribute to efforts to control and monitor the spread of DENVs in endemic areas

    Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

    The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

    Zika virus infection in pregnancy: a protocol for the joint analysis of the prospective cohort studies of the ZIKAlliance, ZikaPLAN and ZIKAction consortia

    INTRODUCTION: Zika virus (ZIKV) infection in pregnancy has been associated with microcephaly and severe neurological damage to the fetus. Our aim is to document the risks of adverse pregnancy and birth outcomes and the prevalence of laboratory markers of congenital infection in deliveries to women experiencing ZIKV infection during pregnancy, using data from European Commission-funded prospective cohort studies in 20 centres in 11 countries across Latin America and the Caribbean. METHODS AND ANALYSIS: We will carry out a centre-by-centre analysis of the risks of adverse pregnancy and birth outcomes, comparing women with confirmed and suspected ZIKV infection in pregnancy to those with no evidence of infection in pregnancy. We will document the proportion of deliveries in which laboratory markers of congenital infection were present. Finally, we will investigate the associations of trimester of maternal infection in pregnancy, presence or absence of maternal symptoms of acute ZIKV infection and previous flavivirus infections with adverse outcomes and with markers of congenital infection. Centre-specific estimates will be pooled using a two-stage approach. ETHICS AND DISSEMINATION: Ethical approval was obtained at each centre. Findings will be presented at international conferences and published in peer-reviewed open access journals and discussed with local public health officials and representatives of the national Ministries of Health, Pan American Health Organization and WHO involved with ZIKV prevention and control activities
