    Over the past three decades, our understanding of the nature, assessment and treatment of childhood mental disorders has increased significantly. Some of the most recent advances come from transdiagnostic and neuropsychological-based approaches. While the relationship of similar neuropsychological deficits with some mental disorders, such as neurodevelopmental and severe mental disorders like schizophrenia or bipolar disorder, is widely established, there is more controversy about their relationship with the so-called internalizing and externalizing disorders. In this article, our goal was to highlight the potential of incorporating cognitive strategies from integrative neuropsychological and transdiagnostic approaches to improve the effectiveness of empirically-supported cognitive-behavioral therapy for internalizing and externalizing mental disorders in childhood and adolescence. The results of the present work indicate that the vast majority of internalizing disorders, including the presence of anxiety, depressive, trauma- and stress-related, and obsessive-compulsive and related disorders, as well as externalizing symptoms (corresponding to conduct disorder and ODD), present neuropsychological deficits and that their consideration may be relevant to improve the effectiveness of psychotherapeutic interventions in children and adolescents by incorporating neuropsychology-based assessment and treatment tools. The inclusion of neuropsychological support strategies in therapy for childhood mental disorders implies an advance and has clear implications for the enhancement of psychological care for childhood mental disorders.Ao longo das últimas três décadas, a nossa compreensão da natureza, avaliação e tratamento das perturbações mentais na infância aumentou significativamente. Alguns dos avanços mais recentes derivam de abordagens transdiagnósticas e neuropsicológicas. Embora a relação de défices neuropsicológicos com algumas perturbações mentais, como as perturbações neurodesenvolvimentais e com perturbações mentais graves, como a esquizofrenia e a perturbação bipolar, seja amplamente reconhecida, existe maior controvérsia acerca da sua relação com as perturbações internalizantes e externalizantes. Este artigo teve como objetivo destacar o potencial de incorporar estratégias cognitivas derivadas de abordagens transdiagnósticas neuropsicológicas integradoras para aumentar a eficácia de tratamentos cognitivo-comportamentais empiricamente validados para perturbações internalizantes e externalizantes na infância e na adolescência. Os resultados do presente trabalho indicam que tanto a vasta maioria de perturbações internalizantes (incluindo perturbações de ansiedade, perturbações depressivas, perturbações relacionadas com trauma e fatores de stress, e perturbações obsessivo-compulsivas e relacionadas) como perturbações externalizantes (como perturbação do comportamento e perturbação desafiante de oposição), apresentam défices neuropsicológicos, e que a consideração destes défices pode ser relevante para melhorar a eficácia de intervenções psicoterapêuticas com crianças e adolescentes, incorporando ferramentas neuropsicológicas de avaliação e tratamento. A inclusão de estratégias neuropsicológicas de suporte na intervenção terapêutica para as perturbações mentais infantis implica um avanço e tem implicações claras na melhoria de cuidados psicológicos a esta população

    <p>Abstract</p> <p>Background</p> <p>Leukotriene B<sub>4 </sub>(LTB<sub>4</sub>) is a potent inflammatory mediator that also stimulates the immune response. In addition, it promotes polymorphonuclear leukocyte phagocytosis, chemotaxis, chemokinesis and modulates cytokines release. Regarding chemical instability of the leukotriene molecule, in the present study we assessed the immunomodulatory activities conferred by LTB<sub>4 </sub>released from microspheres (MS). A previous oil-in-water emulsion solvent extraction-evaporation method was chosen to prepare LTB<sub>4</sub>-loaded MS.</p> <p>Results</p> <p>In the mice cremasteric microcirculation, intraescrotal injection of 0.1 ml of LTB<sub>4</sub>-loaded MS provoked significant increases in leukocyte rolling flux, adhesion and emigration besides significant decreases in the leukocyte rolling velocity. LTB<sub>4</sub>-loaded MS also increase peroxisome proliferator-activated receptor-α (PPARα) expression by murine peritoneal macrophages and stimulate them to generate nitrite levels. Monocyte chemoattractant protein-1 (MCP-1) and nitric oxide (NO) productions were also increased when human umbilical vein and artery endothelial cells (HUVECs and HUAECs, respectively) were stimulated with LTB<sub>4</sub>-loaded MS.</p> <p>Conclusion</p> <p>LTB<sub>4</sub>-loaded MS preserve the biological activity of the encapsulated mediator indicating their use as a new strategy to modulate cell activation, especially in the innate immune response.</p

    The psychological impact due to the coronavirus pandemic (COVID-19) has been evidenced. Some of the variables associated with this have been the presence of previous financial problems, being students or being inactive, all of them issues related to the work and academic scope. Consequently, the main objective of the work was to analyze the mediating role that personal strengths for mental health have in the face of academic/work interference caused by lockdown due to COVID-19 in Spain based on work status (students, workers active and inactive), controlling in turn for other sociodemographic variables (sex and age). For the data collection of this descriptive cross-sectional study, an online survey was used, composed of instruments to assess the degree of interference in academic/work activities (ad hoc), maladaptive coping strategies (COPE-28), resilience (CD-RISC), covitality (SEHS), healthy habits (ad hoc), psychological well-being (WHO-5) and psychological distress (PHQ-4). The results showed: on the one hand, that the groups of students and inactivity showed worse mental health indicators and personal resources, while the opposite effect was found in the group of active workers; and, on the other hand, the PROCESS mediation models (model 4) evidenced a damping effect of personal resources between perceived academic/work interference and psychological adjustment indicators (well-being and psychological distress), regardless of the work category. In conclusion, the protective role of personal resources in psychological adjustment during lockdown due to COVID-19 is highlightedEl impacto psicológico debido a la pandemia por coronavirus (COVID-19) ha sido evidenciado. Algunas de las variables asociadas a éste han sido la presencia de problemas financieros previos, ser estudiantes o encontrarse inactivo, todas ellas cuestiones relacionadas con el ámbito laboral y académico. En consecuencia, el objetivo principal del trabajo fue analizar el papel mediador que tienen las fortalezas personales para la salud mental frente a la interferencia académica/laboral provocada por el confinamiento debido a la COVID-19 en España en función del estatus laboral (estudiantes, trabajadores activos e inactivos), controlando a su vez otras variables sociodemográficas (sexo y edad). Para la recogida de datos del presente estudio descriptivo de corte transversal se utilizó una encuesta online, compuesta por instrumentos para valorar el grado de interferencia en las actividades académicas/laborales (ad hoc), las estrategias de afrontamiento desadaptativas (COPE-28), la resiliencia (CD-RISC), la covitalidad (SEHS), los hábitos saludables (ad hoc), el bienestar psicológico (WHO-5) y malestar psicológico (PHQ-4). Los resultados mostraron, por un lado, que los colectivos de estudiantes y de inactividad manifestaron peores indicadores de salud mental y recursos personales, mientras que el efecto contrario fue hallado en el grupo de trabajadores activos; y, por otro lado, los modelos de mediación PROCESS (modelo 4) evidenciaron un efecto amortiguador de los recursos personales entre la interferencia académica/laboral percibida y los indicadores de ajuste psicosocial (bienestar y malestar psicológico), independientemente de la categoría laboral. En conclusión, se destaca la función protectora de los recursos personales en el ajuste psicosocial durante el periodo de confinamiento por COVID-19

    OBJECTIVE: The aim of this study was to describe growth during puberty in young people with vertically acquired HIV. DESIGN: Pooled data from 12 paediatric HIV cohorts in Europe and Thailand. METHODS: One thousand and ninety-four children initiating a nonnucleoside reverse transcriptase inhibitor or boosted protease inhibitor based regimen aged 1-10 years were included. Super Imposition by Translation And Rotation (SITAR) models described growth from age 8 years using three parameters (average height, timing and shape of the growth spurt), dependent on age and height-for-age z-score (HAZ) (WHO references) at antiretroviral therapy (ART) initiation. Multivariate regression explored characteristics associated with these three parameters. RESULTS: At ART initiation, median age and HAZ was 6.4 [interquartile range (IQR): 2.8, 9.0] years and -1.2 (IQR: -2.3 to -0.2), respectively. Median follow-up was 9.1 (IQR: 6.9, 11.4) years. In girls, older age and lower HAZ at ART initiation were independently associated with a growth spurt which occurred 0.41 (95% confidence interval 0.20-0.62) years later in children starting ART age 6 to 10 years compared with 1 to 2 years and 1.50 (1.21-1.78) years later in those starting with HAZ less than -3 compared with HAZ at least -1. Later growth spurts in girls resulted in continued height growth into later adolescence. In boys starting ART with HAZ less than -1, growth spurts were later in children starting ART in the oldest age group, but for HAZ at least -1, there was no association with age. Girls and boys who initiated ART with HAZ at least -1 maintained a similar height to the WHO reference mean. CONCLUSION: Stunting at ART initiation was associated with later growth spurts in girls. Children with HAZ at least -1 at ART initiation grew in height at the level expected in HIV negative children of a comparable age

    Experience sampling methods for the personalised prediction of mental health problems in Spanish university students: protocol for a survey-based observational study within the PROMES-U project

    IntroductionThere is a high prevalence of mental health problems among university students. Better prediction and treatment access for this population is needed. In recent years, short-term dynamic factors, which can be assessed using experience sampling methods (ESM), have presented promising results for predicting mental health problems.Methods and analysisUndergraduate students from five public universities in Spain are recruited to participate in two web-based surveys (at baseline and at 12-month follow-up). A subgroup of baseline participants is recruited through quota sampling to participate in a 15-day ESM study. The baseline survey collects information regarding distal risk factors, while the ESM study collects short-term dynamic factors such as affect, company or environment. Risk factors will be identified at an individual and population level using logistic regressions and population attributable risk proportions, respectively. Machine learning techniques will be used to develop predictive models for mental health problems. Dynamic structural equation modelling and multilevel mixed-effects models will be considered to develop a series of explanatory models for the occurrence of mental health problems.Ethics and disseminationThe project complies with national and international regulations, including the Declaration of Helsinki and the Code of Ethics, and has been approved by the IRB Parc de Salut Mar (2020/9198/I) and corresponding IRBs of all participating universities. All respondents are given information regarding access mental health services within their university and region. Individuals with positive responses on suicide items receive a specific alert with indications for consulting with a health professional. Participants are asked to provide informed consent separately for the web-based surveys and for the ESM study. Dissemination of results will include peer-reviewed scientific articles and participation in scientific congresses, reports with recommendations for universities’ mental health policy makers, as well as a well-balanced communication strategy to the general public

    Get PDF
    To describe the natural history of SARS-CoV-2 infection in patients with hypertrophic cardiomyopathy (HCM) compared with a control group and to identify predictors of adverse events. Three hundred and five patients [age 56.6 ± 16.9 years old, 191 (62.6%) male patients] with HCM and SARS-Cov-2 infection were enrolled. The control group consisted of 91 131 infected individuals. Endpoints were (i) SARS-CoV-2 related mortality and (ii) severe clinical course [death or intensive care unit (ICU) admission]. New onset of atrial fibrillation, ventricular arrhythmias, shock, stroke, and cardiac arrest were also recorded. Sixty-nine (22.9%) HCM patients were hospitalized for non-ICU level care, and 21 (7.0%) required ICU care. Seventeen (5.6%) died: eight (2.6%) of respiratory failure, four (1.3%) of heart failure, two (0.7%) suddenly, and three (1.0%) due to other SARS-CoV-2-related complications. Covariates associated with mortality in the multivariable were age {odds ratio (OR) per 10 year increase 2.25 [95% confidence interval (CI): 1.12-4.51], P = 0.0229}, baseline New York Heart Association class [OR per one-unit increase 4.01 (95%CI: 1.75-9.20), P = 0.0011], presence of left ventricular outflow tract obstruction [OR 5.59 (95%CI: 1.16-26.92), P = 0.0317], and left ventricular systolic impairment [OR 7.72 (95%CI: 1.20-49.79), P = 0.0316]. Controlling for age and sex and comparing HCM patients with a community-based SARS-CoV-2 cohort, the presence of HCM was associated with a borderline significant increased risk of mortality OR 1.70 (95%CI: 0.98-2.91, P = 0.0600). Over one-fourth of HCM patients infected with SARS-Cov-2 required hospitalization, including 6% in an ICU setting. Age and cardiac features related to HCM, including baseline functional class, left ventricular outflow tract obstruction, and systolic impairment, conveyed increased risk of mortality

    BACKGROUND: Although mental disorders and suicidal thoughts-behaviors (suicidal thoughts and behaviors) are common among university students, the majority of students with these problems remain untreated. It is unclear what the barriers are to these students seeking treatment. AIMS: The aim of this study is to examine the barriers to future help-seeking and the associations of clinical characteristics with these barriers in a cross-national sample of first-year college students. METHOD: As part of the World Mental Health International College Student (WMH-ICS) initiative, web-based self-report surveys were obtained from 13,984 first-year students in eight countries across the world. Clinical characteristics examined included screens for common mental disorders and reports about suicidal thoughts and behaviors. Multivariate regression models adjusted for socio-demographic, college-, and treatment-related variables were used to examine correlates of help-seeking intention and barriers to seeking treatment. RESULTS: Only 24.6% of students reported that they would definitely seek treatment if they had a future emotional problem. The most commonly reported reasons not to seek treatment among students who failed to report that they would definitely seek help were the preference to handle the problem alone (56.4%) and wanting to talk with friends or relatives instead (48.0%). Preference to handle the problem alone and feeling too embarrassed were also associated with significantly reduced odds of having at least some intention to seek help among students who failed to report that they would definitely seek help. Having 12-month major depression, alcohol use disorder, and suicidal thoughts and behaviors were also associated with significantly reduced reported odds of the latter outcome. CONCLUSIONS: The majority of first-year college students in the WMH-ICS surveys report that they would be hesitant to seek help in case of future emotional problems. Attitudinal barriers and not structural barriers were found to be the most important reported reasons for this hesitation. Experimental research is needed to determine whether intention to seek help and, more importantly, actual help-seeking behavior could be increased with the extent to which intervention strategies need to be tailored to particular student characteristics. Given that the preference to handle problems alone and stigma and appear to be critical, there could be value in determining if internet-based psychological treatments, which can be accessed privately and are often build as self-help approaches, would be more acceptable than other types of treatments to student who report hesitation about seeking treatment.status: publishe

    WHO World Mental Health Surveys International College Student Project: Prevalence and Distribution of Mental Disorders

    Increasingly, colleges across the world are contending with rising rates of mental disorders, and in many cases, the demand for services on campus far exceeds the available resources. The present study reports initial results from the first stage of the WHO World Mental Health International College Student project, in which a series of surveys in 19 colleges across 8 countries (Australia, Belgium, Germany, Mexico, Northern Ireland, South Africa, Spain, United States) were carried out with the aim of estimating prevalence and basic sociodemographic correlates of common mental disorders among first-year college students. Web-based self-report questionnaires administered to incoming first-year students (45.5% pooled response rate) screened for six common lifetime and 12-month DSM-IV mental disorders: major depression, mania/hypomania, generalized anxiety disorder, panic disorder, alcohol use disorder, and substance use disorder. We focus on the 13,984 respondents who were full-time students: 35% of whom screened positive for at least one of the common lifetime disorders assessed and 31% screened positive for at least one 12-month disorder. Syndromes typically had onsets in early to middle adolescence and persisted into the year of the survey. Although relatively modest, the strongest correlates of screening positive were older age, female sex, unmarried-deceased parents, no religious affiliation, nonheterosexual identification and behavior, low secondary school ranking, and extrinsic motivation for college enrollment. The weakness of these associations means that the syndromes considered are widely distributed with respect to these variables in the student population. Although the extent to which cost-effective treatment would reduce these risks is unclear, the high level of need for mental health services implied by these results represents a major challenge to institutions of higher education and governments.

    Get PDF
    Trabajo presentado en SPIE Astronomical Telescopes, celebrado en San Diego (California), del 26 de junio al 1 de julio de 2016HARMONI is the E-ELT's first light visible and near-infrared integral field spectrograph. It will provide four different spatial scales, ranging from coarse spaxels of 60 × 30 mas best suited for seeing limited observations, to 4 mas spaxels that Nyquist sample the diffraction limited point spread function of the E-ELT at near-infrared wavelengths. Each spaxel scale may be combined with eleven spectral settings, that provide a range of spectral resolving powers (R 3500, 7500 and 20000) and instantaneous wavelength coverage spanning the 0.5 - 2.4 ¿m wavelength range of the instrument. In autumn 2015, the HARMONI project started the Preliminary Design Phase, following signature of the contract to design, build, test and commission the instrument, signed between the European Southern Observatory and the UK Science and Technology Facilities Council. Crucially, the contract also includes the preliminary design of the HARMONI Laser Tomographic Adaptive Optics system. The instrument's technical specifications were finalized in the period leading up to contract signature. In this paper, we report on the first activity carried out during preliminary design, defining the baseline architecture for the system, and the trade-off studies leading up to the choice of baseline
