Objective There is an evidence gap regarding the predictive accuracy of the triglyceride-glucose (TyG) index for long-term major adverse cardiovascular events (MACEs) in individuals with high cardiovascular risk. The aim of this investigation was to evaluate the predictive value of the TyG index for long-term MACEs in patients at high cardiovascular risk. Methods In total, 483 patients with high cardiovascular risk were included in this analysis. The study population was separated into 2 groups depending on the occurrence of long-term MACEs. The independent predictors of long-term MACEs in patients with high cardiovascular risk were investigated. The long-term prognostic value of the TyG index in these patients was evaluated in terms of MACEs. Results Age, male sex, diabetes mellitus, and the TyG index were demonstrated to be independent predictors of long-term MACE occurrence in patients with high cardiovascular risk. The TyG index was independently related to long-term MACEs in patients with high cardiovascular risk (hazard ratio, 1.003; 95% confidence interval [CI], 1.001–1.006; p=0.011). The receiver operating characteristic curve revealed that the optimum value of the TyG index to predict long-term MACEs in the overall study cohort was >9.68, with 65% sensitivity and 63% specificity (area under the curve, 0.71; 95% CI, 0.65–0.77; p<0.001). Conclusion The TyG index was demonstrated to be an independent predictor of long-term MACE occurrence in patients with high cardiovascular risk who had not been previously diagnosed with cardiovascular disease.

Objective Prospective data of risky online gamers in Turkey is missing. Therefore, we aimed to investigate the change in gaming behaviors and addiction rates of Travian players within two years to search diagnostic stability of internet gaming disorder and some psychosocial risk factors. Methods 110 responders completed the whole questionnaire package including 21-item Game Addiction Scale (GAS), Satisfaction with Life Scale (SLS), Rosenberg Self-Esteem Scale (RSES), and Multi-dimensional Scale of Perceived Social Support (MSPSS). A hierarchical linear modeling approach was followed to test the linear change in game addiction scores of the participants from 2013 to 2015. Results GAS scores of gamers significantly decreased within two years (p=0.026). MSPSS scores significantly and negatively associated with GAS scores (p<0.001) and the negative association of time remained significant (p=0.035). Decrement in the MSPSS scores in two years was associated with increment in GAS scores. 9 (90%) of 10 participants with internet gaming disorder according to monothetic format and 26 (52%) of 50 participants with internet gaming disorder according to polythetic format were found to not to meet the diagnosis in the follow-up. 33 out of all participants reported that they were not playing any online games for at least last 6 months. Conclusion Social support seems to be a protective factor for game addiction and diagnosis of internet gaming disorder has low temporal stability among Travian players in Turkey.

<P>Submarine landslides form very complex depositional and erosional features on the seafloor, and their dynamics and triggering processes are yet to be understood completely. Numerous studies are being undertaken both because of the scientific significance but also for their potential harm to seafloor infrastructure and coastal areas. This study investigates the styles and causes of landsliding along the western margin of the Ulleung Basin in the East Sea, based on multiple sparker, subbottom profiler, multibeam echosounder and sediment core datasets collected in 2015. The bathymetric analyses indicate that the southern slope of the Ulleung Basin has experienced at least seven submarine failures. These failures left clear arcuate-shaped scarps that initiated at water depths of similar to 600 m. The observed headwall scarps have heights that exceed 60 m and appear to be the result of retrogressive-type failures. Seismic reflection data clearly image the basal sliding surface that is characterized by a prominent high-amplitude reflector. Chaotic-totransparent seismic facies occur immediately downslope of the headwall scarps; these represent similar to 20 m thick landslide deposits. Gravity cores taken from areas adjacent to the scars suggest that these slides are older than ca. 97 ka. Interpretation of the present data shows that faults appear to cut recent sediments upslope of scarps, and that the slope may still be in an active phase of failure. Seismic data also image various overpressurized gases and/or gas fluids, as evidenced by the occurrence of pockmarks and seismic chimneys in upslope or adjacent areas of the scarps. Hence, earthquakes associated with tectonic activity and development of fluid overpressure may have acted as the main conditioning factor for destabilizing the slope sediments. Geotechnical stability analyses indicate that the sampled slope sediments are exceptionally stable under present-day conditions, even under seismic loading. This finding points to additional forces such as excess pore pressure caused by gas fluids at the times of slide emplacement.</P>
