In carbon-ion radiotherapy (CIRT), secondary neutrons are produced by nuclear interactions in the beamline devices or patient. Herein, the characteristics of secondary neutrons in CIRT with energy scanning (ES) were evaluated. Neutron ambient dose equivalents (H*(10)) were measured using WENDI-II. The neutron energy spectrum was calculated using the Monte Carlo simulation. Measurement and calculation were performed under realistic case scenarios using maximum beam energies (Emax) of 290, 350 and 400 MeV u -1. Moreover, H*(10) in ES was compared with H*(10) in range-shifter scanning (RS) and hybrid scanning (HS). H*(10) in Emax = 290 MeV u-1 was 65% less than that in Emax = 400 MeV u-1. At Emax = 350 MeV u-1, H*(10) in ES at θ = 120 was 42% of that at θ = 60. The neutron dose in ES CIRT decreased to approximately 60 and 70% of that in RS and HS CIRT, respectively, at 50-cm distance from the beam axis. This large prospective cohort study sought to confirm the incremental prognostic value of coronary computed tomographic angiography (CCTA) measured over a prolonged follow-up duration. CCTA has diagnostic and prognostic value but data supporting its long-term prognostic value in a large prospectively recruited cohort with suspected coronary artery disease (CAD) has been limited. Consecutive patients (without history of myocardial infarction, revascularization, cardiac transplantation, and congenital heart disease) were prospectively enrolled. CCTA was evaluated for CAD severity, total plaque score (TPS), and left ventricular ejection fraction. Patients were followed for major adverse events (MAE) and major adverse cardiac events (MACE).Over a total of 99 months, 8667 consecutive CCTA patients (mean age = 57.1 ± 11.1 years, 52.9% men) were prospectively enrolled and followed for a mean duration of 7.0 ± 2.6 years. At follow-up, there were a total of 723 MAE, 278 MACE, 547 all-cause deaths, 110 cardiac deat of coronary atherosclerosis portends an excellent prognosis. Patients with increasing non-obstructive plaque burden have worse prognosis and a TPS threshold ≥5 may identify a population that may benefit from statin therapy. New psychoactive substance (NPS) use can negatively impact health and may result in drug-related hospital admissions (DRHAs). Irish youth reported very high rates of NPS use by international standards, the most common being synthetic cannabinoids and cathinones. There was a rapid expansion in specialist shops, called head shops, selling NPS in 2010. Government responded to public protests about head shops by enacting legislation in May and August 2010 to end this trade. Many academics argued that such actions would prove futile. We sought to determine if changes in head shop activity coincided with changes in DRHA. The national database on admissions to general hospitals hospital in-patient enquiry was examined focusing on young adults admitted from 2008 to 2012, and all emergency admissions with an International Classification of Diseases-10 diagnosis of mental disorder related to any drug (F11-F19) were identified. Joinpoint regression analysis was utilized to explore for the presence of trend changes in DRHA. Joinpoint regression analysis identified a significant downward trend change which occurred in June 2010 (95% CI February 2010 to January 2011). DRHA increased by 0.5% (95% CI 0.1-0.9) per month prior to this and then fell by 2.6% (95% CI -1.4 to -3.8) per month over the next 16 months. Cessation of NPS sale by head shops coincided with a reversal in the upward trend of emergency hospital admissions related to drugs. selleck Although correlation does not confirm causation, legislation which successfully curtails the commercial sale of NPS may result in reduced hospitalizations.
