gaming disorder (IGD) has been related to a wide range of detrimental psychological and health consequences. The purpose of the present pilot study was to test the direct and indirect relationships between IGD and emotional trauma, body image dissatisfaction, social anxiety, loneliness, depression, and self-esteem. A total of 242 online gamers completed a survey comprising a comprehensive battery of psychometric self-report scales concerning aforementioned variables. Results indicated that IGD was significantly correlated with all the variables except for body image dissatisfaction. Path analysis indicated an indirect relationship between childhood emotional trauma and IGD through depressive symptoms, while adjusting for gender, age, and number of hours gaming. The findings of the present study indicate that online gamers with a history of emotional abuse and/or neglect have higher levels of depressive symptoms, and that depressive symptoms are important risk factors of IGD.

BACKGROUND: In Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon. METHODS/DESIGN: The objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade. DISCUSSION: As school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.

Previous results from our laboratory suggest a combined effect of anger-suppression and family history of cardiovascular disorders in determining cardiovascular responses to mental stress. The present study was designed to determine the effect sizes in cardiovascular reactivity associated with biological risk, psychological risk and the combination of these risk factors using meta-analytical techniques. Results from three independent studies with almost identical experimental procedures provided the basis for the calculation of d, the difference between the means of two groups, divided by the pooled within-group standard deviation. Effect sizes were calculated for the comparison of high versus low biological hypertension risk, high versus low anger suppression, and high versus low combined risk. The results show the largest effect sizes for the comparison of high versus low combined risk. The effect sizes associated with the combination of risk factors were larger than the sum of the effect sizes associated with either factor alone. We conclude that the combination of biological and psychological risk factors in determining cardiovascular reactivity to mental stress is more than the sum of its parts. These findings are discussed in terms of a better understanding of the over-additive effects of multiple cardiovascular risk factors on cardiovascular morbidity and mortality. [less ▲]

Protein Topology Graph Library (PTGL) is a database application for the representation and retrieval of protein topologies. Protein topologies are based on a graph-theoretical protein model at secondary structure level. Different views on protein topology are given by four linear notations for their characterization. Protein topologies can be derived at different description levels considering alpha- and beta-structures. The on-line search tool is based on an object-relational database and provides a query browser for data interrogation by string patterns, keyword queries and sequence similarity. Protein topologies are represented both as schematic diagrams and as three-dimensional images. [less ▲]

With growing amount of experimental data, the number of known protein structures also increases continuously. Classification of protein structures helps to understand relationships between protein structure and function. The main classification methods based on secondary structures are SCOP, CATH and TOPS, which all classify under different aspects, and therefore can lead to different results. We developed a mathematically unique representation of protein structure topologies at a higher abstraction level providing new aspects of classification and enabling for a fast search through the data. Protein Topology Graph Library (PTGL; http://ptgl.zib.de) aims at providing a database on protein secondary structure topologies, including search facilities, the visualization as intuitive topology diagrams as well as in the 3D structure, and additional information. Secondary structure-based protein topologies are represented uniquely as undirected labeled graphs in four different ways allowing for exploration under different aspects. The linear notations, and the 2D and 3D diagrams of each notation facilitate a deeper understanding of protein topologies. Several search functions for topologies and sub-topologies, BLAST search possibility, and links to SCOP, CATH and PDBsum support individual and large-scale investigation of protein structures. Currently, PTGL comprises topologies of 54,859 protein structures. Main structural patterns for common structural motifs like TIM-barrel or Jelly Roll are pre-implemented, and can easily be searched.

BACKGROUND: The protein tyrosine phosphatase nonreceptor type 2 (PTPN22) has been established as a type 1 diabetes susceptibility gene. A recent study found the C1858T variant of this gene to be associated with lower residual fasting C-peptide levels and poorer glycemic control in patients with type 1 diabetes. We investigated the association of the C1858T variant with residual beta-cell function (as assessed by stimulated C-peptide, proinsulin and insulin dose-adjusted HbA1c), glycemic control, daily insulin requirements, diabetic ketoacidosis (DKA) and diabetes-related autoantibodies (IA-2A, GADA, ICA, ZnT8Ab) in children during the first year after diagnosis of type 1 diabetes. METHODS: The C1858T variant was genotyped in an international cohort of children (n = 257 patients) with newly diagnosed type 1 diabetes during 12 months after onset. We investigated the association of this variant with liquid-meal stimulated beta-cell function (proinsulin and C-peptide) and antibody status 1, 6 and 12 months after onset. In addition HbA1c and daily insulin requirements were determined 1, 3, 6, 9 and 12 months after diagnosis. DKA was defined at disease onset. RESULTS: A repeated measurement model of all time points showed the stimulated proinsulin level is significantly higher (22%, p = 0.03) for the T allele carriers the first year after onset. We also found a significant positive association between proinsulin and IA levels (est.: 1.12, p = 0.002), which did not influence the association between PTPN22 and proinsulin (est.: 1.28, p = 0.03). CONCLUSIONS: The T allele of the C1858T variant is positively associated with proinsulin levels during the first 12 months in newly diagnosed type 1 diabetes children. [less ▲]

Computer-aided diagnosis and stratification of COVID-19 based on chest X-ray suffers from weak bias assessment and limited quality-control. Undetected bias induced by inappropriate use of datasets, and improper consideration of confounders prevents the translation of prediction models into clinical practice. By adopting established tools for model evaluation to the task of evaluating datasets, this study provides a systematic appraisal of publicly available COVID-19 chest X-ray datasets, determining their potential use and evaluating potential sources of bias. Only 9 out of more than a hundred identified datasets met at least the criteria for proper assessment of the risk of bias and could be analysed in detail. Remarkably most of the datasets utilised in 201 papers published in peer-reviewed journals, are not among these 9 datasets, thus leading to models with a high risk of bias. This raises concerns about the suitability of such models for clinical use. This systematic review highlights the limited description of datasets employed for modelling and aids researchers to select the most suitable datasets for their task. [less ▲]

This thesis examines the scope, role and contemporary application of the traditional principle of public hearings, with a particular focus on the specific dispute resolution system of investor-state arbitration. Whereas there have been extensive discussions in recent years surrounding developments which aim to increase the procedural openness and transparency of this traditionally private dispute resolution system, the emergence of a distinct requirement of holding public hearings in such contexts has not yet been given much attention. This thesis seeks to provide a better understanding of public hearings in investment treaty arbitration. By going beyond the usual narrative of the legitimacy and policy objectives of transparency, a more systematic and comprehensive approach to the issue of public hearings in investor-state arbitration is adopted. In addressing existing gaps in the literature, this thesis contends that current developments related to the principle of public hearings should not be analysed as a phenomenon specific to investor-state arbitration, but should instead be analysed within the broader context of the analogous developments at both the domestic and international level. In conducting such an investigation, this thesis situates the debate surrounding public hearings in investment treaty arbitration within a broader legal landscape, encompassing both national and international courts and tribunals. By examining the evolution of public hearings, it is argued that a steady shift in the understanding of the principle of public hearings over time may be detected. Public hearings have gone from serving merely as a means of protecting the individual from the secrecy and arbitrariness of the state, to becoming a democratic tool which the public is entitled to use not only in order to monitor and evaluate the administration of justice, but also as a platform for facilitating further public debate. In other words, the thesis demonstrates a shift in the understanding of the principle of public hearings from being a mere right of an individual to be heard in an open court, to the (additional) right of the general public to have an insight into what goes on in the courtroom and the active duty of the courts to ensure that this right is respected. This latter aspect of the principle of public hearings is subject to comparative analysis which examines the normative and practical solutions adopted by national and international courts when applying the principle of public hearings. While detecting a divergent legal landscape when it comes to providing public access to hearings, this thesis reveals a general trend towards greater regulation of the ways in which the public may obtain such access. What is more, it shall be shown that, in an era of expanded media coverage of public hearings, the subsequent enlargement of the audiences for such hearings, and the possibility to instantly disseminate information about proceedings through various technologies creates new paths for procedural openness and new challenges for the courts. Based on the findings of this comparative analysis, the thesis argues that it is not only the principle of public hearings which has been renewed and transformed. In seeking to adapt to the principle, the procedures in which the principle of public hearings operates have also started to change. This comparative analysis then forms the basis upon which a critical analysis and in-depth assessment is provided within the context of public hearings in investor-state arbitration. From a more “dispute-oriented” perspective, the thesis looks into the considerations and challenges that ought to be taken into account by arbitral tribunals and parties when organising a public hearing. By not losing sight of the implications for the system as a whole, however, the thesis addresses the future impact that the introduction of public hearings into the system investor-state arbitration may have on that system and, notably, upon its procedures. The key finding here is that the increasing relevance of public hearings in investor-state arbitration constitutes merely one part of the overall evolution of the “public” dimension of the requirement of public hearings. When taking these developments together, the thesis concludes that the debate on what constitutes a truly public hearing has entered a new epoch, with new actors and new challenges. [less ▲]
