The aim was to develop and validate an instrument to track online problem poker gamblers with player account-based gambling data (PABGD). We emailed an invitation to all active poker gamblers on the online gambling service provider Winamax. The 14,261 participants completed the Problem Gambling Severity Index (PGSI). PGSI served as a gold standard to track problem gamblers (i.e., PGSI≥5). We used a stepwise logistic regression to build a predictive model of problem gambling with PABGD, and validated it. Of the sample 18% was composed of online poker problem gamblers. The risk factors of problem gambling included in the predictive model were being male, compulsive, younger than 28 years, making a total deposit>0 euros, having a mean loss per gambling session>1.7 euros, losing a total of>45 euros in the last 30 days, having a total stake>298 euros, having>60 gambling sessions in the last 30 days, and multi-tabling. The tracking instrument had a sensitivity of 80%, and a specificity of 50%. The quality of the instrument was good. This study illustrates the feasibility of a method to develop and validate instruments to track online problem gamblers with PABGD only. © 2016 John Wiley & Sons, Ltd. Source

Purpose: This study aims to estimate the prevalence of depressive symptoms among adolescents seen in hospital emergency departments and to investigate the concordance between self-reported adolescent depression and parental perceptions of their adolescents' health status. Method: A multicentre cross-sectional survey in three emergency departments receiving adolescents in Ile-de-France took place in 2010. All adolescents completed a questionnaire including the Adolescent Depression Rating Scale (ADRS) and a series of questions concerning somatisation and risk behaviours. Parents simultaneously completed a questionnaire collecting their perceptions of their adolescent's health status. Results: The study included 346 adolescents, and of them, 320 were fully analysed. ADRS scores were in the normal range for 70.6 % of the sample (score of <3) (n = 226); 19.4 % (n = 62) showed moderate depressive symptoms (3 ≤ score < 6), and 10.0 %, severe depressive symptoms (score of ≥6) (n = 32). We observed a wide discrepancy between adolescent depression, determined by a score on a self-administered scale, and parental perceptions of it. Conclusion: Routine use of a self-administered questionnaire in emergency units could enable identification of adolescents with moderate or severe depressive symptoms. The present study confirms the importance of increasing parental awareness of their adolescent children's depressive symptoms. © 2013 Springer-Verlag Berlin Heidelberg. Source

Background: Internet-based interventions targeted at the most at-risk gamblers could reduce the treatment gap for addictive disorders. Currently, no clinical trial has included non-treatment-seeking patients who have been recruited directly in their gambling environment. This study was the first exclusively Internet-based randomized controlled trial among non-help-seeking problem gamblers with naturalistic recruitment in their gambling environment. Objective: The aim of this study was to assess the efficacy of three modalities of Internet-based psychotherapies with or without guidance, compared to a control condition, among problem gamblers who play online poker. Methods: All active poker gamblers on the Winamax website were systematically offered screening. All problem poker gamblers identified with a Problem Gambling Severity Index (PGSI) score of ≥5 were eligible to be included in the trial. Problem gamblers were randomized into four groups: (1) waiting list (control group), (2) personalized normalized feedback on their gambling status by email, (3) an email containing a self-help book to be downloaded with a Cognitive Behavioral Therapy (CBT) program without guidance, and (4) the same CBT program emailed weekly by a trained psychologist with personalized guidance. Efficacy was assessed based on the change in PGSI between baseline and 6 weeks (end of treatment) or 12 weeks (maintenance) and supported by player account-based gambling data automatically collected at the three time points. Results: All groups met high attrition rates (83%), but the group with guidance had a significantly higher dropout rate than the other three groups, including the control group. Although all groups showed some improvement, with a mean decrease of 1.35 on the PGSI, no significant difference in efficacy between the groups was observed. One-third of the problem gamblers fell below the problem gambling threshold at 6 weeks. Conclusions: Guidance could have aversively affected problem gamblers who had not sought help. Despite the lack of significant difference in efficacy between groups, this naturalistic trial provides a basis for the development of future Internet-based trials in individuals with gambling disorders. Comorbidities, natural course of illness, and intrinsic motivation seem to be critical issues to consider in future designs. Source

Quintus Technologies (formerly Avure Technologies) has installed a hot isostatic press (HIP) at the Anhui Yingliu Group Huoshan Casting Co Ltd foundry in Anhui province, China. The new press, model QIH 1.6 x 2.5–2000–1400M URC, operaties at a pressure of 200 MPA (29,000 psi) and temperatures up to 1400°C (2552°F). It can produce complex components with improved fatigue strength and extended service life, the company says. The HIP has a work zone of 1600 mm (63 inches) in diameter and 2500 mm (98 inches) in height which can accommodate the size requirements for production of large aircraft engine casings and core components for nuclear power, marine engineering, metallurgy, and other applications.

Quintus Technologies reports that it will supply two additional hot isostatic presses (HIPs) to China’s Anhui Yingliu Group. This comes less than three months after Anhui Yingliu inaugurated what is said to be world's largest 2000-bar HIP, also made by Quintus. Quintus says that its HIPs can achieve 100% of maximum theoretical density and improve the ductility and fatigue resistance of critical, high-performance materials. The presses on order will be equipped with Quintus’ uniform rapid cooling (URC) technology for simultaneous heat treatment. The two new presses, models QIH 173 L and QIH 48, feature work zones of 800 mm (32 inches) by 2500 mm (98 inches) and 375 mm (15 inches) by 1200 mm (47 inches) respectively. Adding the smaller scale presses could boost total foundry capacity while extending capabilities in material and process development, Quintus says. Anhui Yingliu also signed a Service Level agreement with Quintus Technologies. The presses will be installed at the company’s foundry in Huoshan County, Anhui province, China. ‘There is no question that Anhui Yingliu is leading the way and setting the stage for the future growth for hot isostatic pressing and advanced material processing, not only in China but throughout Asia,’ said Peter Henning, business unit director, advanced material densification, at Quintus.
