Alive and kicking: suicide rates and major soccer events in Austria, Germany and Switzerland

BACKGROUND Major sporting events are postulated to reduce suicide rates by increased social connectedness, by identifying with winning teams, or, conversely, to increase suicide rates by the 'broken promise effect'. METHODS In our observational epidemiological study, we investigated changes in suicide rates between 1970 and 2017 in Austria, Germany and Switzerland during the European and World Soccer Championships in general, and on days that the home team played, won or lost. RESULTS Combining all three studied nations no statistically significant change in the incidence of daily suicides during soccer championships compared to a control period was noted (38.29 ± 9.02 vs. 37.33 ± 10.58; incidence risk ratio = 1.03; 95% confidence interval: 1.01-1.05, P = 0.05). Essentially, no differences in the expected directions were found, and none remained statistically significant after correcting for multiple comparisons in subgroups for country, age and gender in all three studied countries. Compared to a control period, neither a significant difference in the respective national suicide rate was found after Germany's four championship victories nor after Austria's emotional only win over Germany. CONCLUSION Our results do not support the assumption of increased social connectedness and, thus, lowered suicide risk during major sporting events or changes in suicide risk depending on the outcome of important games as predicted by the broken promise effect or changes in self-efficacy by identification with winning teams

TCT-4 Efficacy and Safety of Concurrent Administration of Clopidogrel-loading (600mg) and Prasugrel-loading (60mg) in Patients with Acute ST-Segment Elevation Myocardial Infarction

Background: Current STEMI guideline recommendations limit the use of prasugrel to clopidogrel-naïve patients. However, in daily clinical practice a considerable proportion of STEMI patients undergoing primary PCI are preloaded with clopidogrel. Whether the use of prasugrel in clopidogrel pretreated STEMI patients is safe remains unknown. Similarly, the efficacy of a combined loading dose regimen has not been evaluated. Methods: Between 1 September 2009 and 15 October 2012, a total of 1,157 STEMI patients were included in the randomized COMFORTABLE AMI trial (NCT 00962416) and 891 STEMI patients in the SPUM ACS registry (NCT 01000701) at 12 centers. Patients were divided into three groups according to type of peri-procedural antiplatelet loading: (1) Clopidogrel and subsequent Prasugrel loading dose [CP], (2) Prasugrel loading dose alone [P] (3) Clopidogrel loading dose alone [C]; 23 patients were excluded because they were not exposed to Clopidogrel and Prasugrel. The primary safety endpoint was the rate of BARC type 3, 4 and 5 bleeding at 30 days. The primary efficacy endpoint was the composite of cardiac death, nonfatal MI and nonfatal stroke at 30 days. Outcomes were analyzed using Cox's Regressions (crude) and multinomial ITPW weighted Cox's Regressions. Results: A total of 2,025 patients were analysed of whom 428 (21.1%) had received CP, 447 (22.1%) patients P alone, and 1,150 (56.8%) patients C alone. The primary safety endpoint was observed among 1.2% of CP, 1.6% of P, and 1.5% of C patients (CP vs C ad. HR 0.99 (0.36-2.72), PC vs P ad. HR 0.73 (0.22-2.41). The primary safety endpoint occurred less frequently among CP (1.9%) compared with C patients (5.0%, adjusted HR 0.47 (0.22-1.00), but with similar frequency among P and C patients (2.9% vs 5.0%, ad. HR 0.68 (0.27-1.73). The net clinical benefit outcome parameter tended to be lower among CP (2.8%) compared with C patients (6.3%, ad. HR 0.56 (0.30-1.05), whereas no significant difference was observed between P and C patients (3.8% vs 6.3%, ad. HR 0.85 (0.39-1.86). Conclusions: Among STEMI patients preloaded with Clopidogrel, the concurrent administration of a Prasugrel loading dose appears safe and potentially more effective than Clopiogrel alone

Nucleolar-nucleoplasmic shuttling of TARG1 and its control by DNA damage-induced poly-ADP-ribosylation and by nucleolar transcription

Macrodomains are conserved protein folds associated with ADP-ribose binding and turnover. ADP-ribosylation is a posttranslational modification catalyzed primarily by ARTD (aka PARP) enzymes in cells. ARTDs transfer either single or multiple ADP-ribose units to substrates, resulting in mono- or poly-ADP-ribosylation. TARG1/C6orf130 is a macrodomain protein that hydrolyzes mono-ADP-ribosylation and interacts with poly-ADP-ribose chains. Interactome analyses revealed that TARG1 binds strongly to ribosomes and proteins associated with rRNA processing and ribosomal assembly factors. TARG1 localized to transcriptionally active nucleoli, which occurred independently of ADP-ribose binding. TARG1 shuttled continuously between nucleoli and nucleoplasm. In response to DNA damage, which activates ARTD1/2 (PARP1/2) and promotes synthesis of poly-ADP-ribose chains, TARG1 re-localized to the nucleoplasm. This was dependent on the ability of TARG1 to bind to poly-ADP-ribose. These findings are consistent with the observed ability of TARG1 to competitively interact with RNA and PAR chains. We propose a nucleolar role of TARG1 in ribosome assembly or quality control that is stalled when TARG1 is re-located to sites of DNA damage
