The purpose of this study was to investigate the effectiveness of a sensorimotor rhythm (SMR) neurofeedback training (NFT) and biofeedback training (BFT) intervention on ice hockey shooting performance. Specifically, the purpose was to examine (a) whether an NFT/BFT program could improve ice hockey shooting performance, (b) whether the implementation of an SMR-NFT intervention leads to neurological adaptations during performance, and (c) whether such neurological changes account for improvement in shooting performance. Using a longitudinal stratified random control design, results demonstrated that while both SMR-NFT/BFT and control groups improved performance, the rate of improvement for the SMR-NFT/BFT group was significantly higher than the control. Participants in the SMR-NFT/BFT group demonstrated the ability to significantly increase SMR power from pre- to postintervention in the lab. However, no significant changes in SMR power were found during shooting performance. This result may be suggestive of differing cortical activity present during motor-skill preparation.BACKGROUND AND AIMS HCV is associated with an increased risk of cardiovascular events (CV). Whether HCV clearance by direct-acting antivirals (DAA) reduces incident CV disease is poorly understood. We investigate whether HCV eradication reduces CV events. METHODS In a prospective multicentre study, 2204 HCV patients (F0-F229.5%, F3-F4 70.5%) were enrolled. Males were 48%, median age was 68 (59-74) years and BMI 25.9 (23.1-28); 24.7% were smokers, 18% had diabetes, 13.2% had cholesterol levels >200 mg/dl and 9.1% took statins, 44% had hypertension. During an overall median follow-up of 28 (24-39) months, incident CV events, such as ischemic heart disease (IHD) and ischemic cerebral stroke (ICS), were recorded. An overall of 2204 patients were evaluated as control group and 1668 patients after HCV elimination were followed as a case group. Curaxin 137 Factors associated with CV events were evaluated by uni- and multi-variate analyses. RESULTS Incident CV rates per 100 patient years in pre-treatment and untreated controls and treated cases were 1.12, 1.14 and 0.44 (p = 0.0001 vs. controls), respectively, and a decreased of relative risk (RR = 0.379; p = 0.0002) was observed. CV risk was 2.0-3.5 times lower then in controls (HR 3.671; 95%C.I.1.871-7.201; p less then 0.001). The calculated number of patients to be treated to get a benefit in a patient was 55.26. The annual incidence reduction of CV events was 0.68%. HCV clearance was independently associated with CV events reduction (OR, 4.716; 95% C.I.1.832-12.138; p = 0.001). CONCLUSIONS HCV clearance by DAA reduces CV events (IHD and ICS) with both clinical and socio-economic benefits. BACKGROUND AND AIMS Risk assessment studies on the impact of carotid intima-media thickness (CIMT) on cardiovascular events (CVEs) often apply a linear relationship in Cox models of proportional hazards. However, CVEs are mostly induced through rupture of plaques driven by nonlinear mechanical properties of the arterial wall. Hence, the risk response might be nonlinear as well and should be detectable in CVE incidence data when associated with CIMT as surrogate variable for atherosclerotic wall degeneration. METHODS To test this hypothesis, we investigate the KORA F4 study comprising 2580 participants with CIMT measurements and 153 first CVEs (86 strokes and 67 myocardial infarctions). CIMT is only a moderate predictor of CVE risk due to confounding by attained age. Biological evidence suggests that age-related CIMT growth is not entirely connected with atherosclerosis. To explore the complex relations between age, CIMT and CVE risk, we apply linear and nonlinear models of both CIMT and dnCIMT, defined as deviation from a sex and age-adjusted normal value. RESULTS Based on goodness-of-fit and biological plausibility, threshold and logistic step models clearly reveal nonlinear risk response relations for vascular covariables CIMT and dnCIMT. The effect is more pronounced for models involving dnCIMT as novel risk factor, which is not correlated with age. CONCLUSIONS Compared to the standard approach of risk assessment with linear models involving CIMT, the application of excess dnCIMT with nonlinear risk responses leads to a more precise identification of asymptomatic high risk patients, especially at younger age. BACKGROUND AND AIMS Patients with myeloproliferative neoplasms often succumb to cardiovascular events, but little is known on the early stages of their vascular disease. We studied how patients with JAK2 V617F positive essential thrombocythemia (ET) without overt atherosclerotic disease differed from control subjects in the progression of carotid artery stiffness and preclinical atherosclerosis. METHODS Thirty-six patients with JAK2 V617F positive ET and 38 age-, gender- and Framingham coronary heart disease (CHD) -matched control subjects were examined twice within 4 years. Clinical and laboratory testing, echo-tracking ultrasound of carotid arteries, coronary calcium measurement and digital plethysmography were performed (ClinTrials.gov NCT03828422). RESULTS Coronary calcium correlated with the Framingham CHD risk score at the first examination in the control group (rs = 0.410), but not among the ET patients (rs = 0.116). Both groups progressed in coronary calcium, but the outliers were more prominent among ET patients. Carotid artery stiffness increased with time in the ET patients much more than in the control group the increase in β-index 1.95 (SD 2.18) vs. 0.22 (SD 1.99), p less then 0.001, and the increase in carotid pulse wave velocity 0.72 (SD 0.92) vs. 0.08 (SD 0.72) m/s, p = 0.001. There was no correlation between carotid stiffness and Framingham CHD risk in either group. Digital endothelial function did not change. CONCLUSION Carotid artery stiffness progressed faster in patients with JAK2 V617F positive ET than in control subjects. Coronary calcium correlated with the Framingham CHD risk only in control subjects. This indicates that JAK2 V617F positive ET acted as a non-classical risk factor for vascular disease.
