Background-The clinical features of newly diagnosed Japanese patients with Takayasu arteritis and its age or sex specificities are unknown. Methods and Results-We analyzed information from nationwide registration forms submitted by patients with Takayasu arteritis between April 2001 and March 2011 as part of a research program by the Japanese Ministry of Health, Labor and Welfare. Among the 7779 patients who submitted their forms, 1372 newly registered patients with Takayasu arteritis were enrolled; 83.8% were female. The median age at onset was 35 years, which was significantly higher in male patients (median, 43.5 years) than in female patients (median, 34 years; P<0.001). Local symptoms and findings were most commonly observed in the cervicobrachial area, with more complaints in the head or neck than in the upper limbs. Approximately 85% of the patients had vascular involvements in the aortic arch or its major branches; many young female patients had localized lesions. Although male patients had extensive aortic lesions or aneurysms with more complications, localized abdominal lesions were relatively more frequent in male patients with age at onset >40 years than in other agesex groups. Disease statuses were severe in patients who registered at ≥1 year after onset. Conclusions-The

Tumor-infiltrating Foxp3+ Tregs were positively correlated with intratumoral COX-2 expression and were associated with a worse RFS, especially among patients with node-negative NSCLC.

NOGAMI A et al.(5) View the monitor during imaging During imaging, the heart rate must be continuously monitored using a pulse oximeter or an ECG monitor. (6) Prepare for unexpected situations It should be ensured that the room is equipped with an electrical defibrillator to be used in an emergency, if necessary. A hospital manual for handling unexpected situations should be established. In addition, it should be kept in mind that the threshold and lead resistance need to be re-measured after imaging and the mode needs to be returned to the original setting.Recommendations are shown in Table 6. Electrophysiology StudiesThe clinical significance of induced arrhythmia depends on the underlying heart disease, type of arrhythmia, and induction protocol. Electrophysiology studies are considered less useful in patients with frequent premature ventricular contraction (PVCs) without structural heart disease.
