Background: Optimal periprocedural oral anticoagulant (OAC) therapy before catheter ablation (CA) for atrial fibrillation (AF) and the safety profile of OAC discontinuation during the remote period (from 31 days and up to 1 year after CA) have not been well defined.Methods and Results: The RYOUMA registry is a prospective multicenter observational study of Japanese patients who underwent CA for AF in 2017–2018. Of the 3,072 patients, 82.3% received minimally interrupted direct-acting OACs (DOACs) and 10.2% received uninterrupted DOACs. Both uninterrupted and minimally interrupted DOACs were associated with an extremely low thromboembolic event rate. Female, long-standing persistent AF, low creatinine clearance, hepatic disorder, and high intraprocedural heparin dose were independent factors associated with periprocedural major bleeding. At 1 year after CA, DOAC was continued in 55.9% of patients and warfarin in 56.4%. The incidence of thromboembolic and major bleeding events for 1 year was 0.3% and 1.2%, respectively. Age ≥73 years, dementia, and AF recurrence were independently associated with major bleeding events. Univariate analyses revealed that warfarin continuation and off-label overdose of DOACs were risk factors for major bleeding after CA.Conclusions: High intraprocedural dose of heparin was associated with periprocedural major bleeding events. At 1 year after CA, over half of the patients had continued OAC therapy. Thromboembolic events were extremely low; however, major bleeding occurred in 1.2%. Age ≥73 years, dementia, and AF recurrence were independently associated with major bleeding after CA.

We investigated the effects of citric acid and lemon juice on iron absorption and improvement of anemia in iron-deficient rats. In Expt. 1, rats were administered ferric iron solution (2 mg/kg) with various concentrations of citric acid (1 − 6%) by a single oral gavage. The serum iron levels were significantly higher in rats treated with citric acid than those without citric acid. In Expt. 2, anemic rats were administered ferric iron solution (control) with 1% citric acid or diluted lemon juice containing 1% citric acid by oral gavage dose of 2 mg Fe3+/kg/day for 20 d. Heart weight and unsaturated iron-binding capacity (UIBC) were significantly lower in the citric acid group, whereas serum iron level and hematocrit value were significantly higher in the citric acid group than in the control group. Hemoglobin concentration was significantly higher in the citric acid group and lemon juice group. These results suggest beneficial effects of citric acid and lemon juice on iron bioavailability.

Abstract: In recent migration literature, three distinctive features in the sex ratio of annual interprefectural migration in Japan since the 1950s have been identified and explained: (1) an upward trend, (2) a persistently high level, and (3) systematic fluctuations around the trend. We first show in this paper that these three features can also be clearly seen in the sex ratio of non-metropolitan out-migration rates in the launching stage (i.e. between graduation from middle school and acquirement of the first job) of the life course of the Japanese. We then explain these features in terms of (1) the changing and persistent ideologies that orient and constrain the behaviors of Japanese household members and (2) the changes in the spatial economy of Japan. To gain further insights, we also show the systematic effects of educational attainment and sibling status on the non-metropolitan out-migration propensities of the Japanese in the launching stage of their life course. Our findings suggest that the migration propensities will continue to be highly selective with respect to gender (higher for males than for females) and educational attainment (higher for the better educated and lower for the less educated) but will be little affected by sibling status. With respect to the changes in the spatial economy, our findings also suggest that the migration responses will be much greater for males than for females, and that among males the responses will be particularly intense at the two extremes of educational attainment, especially the upper extreme.

Few studies have reviewed the roles of perfusion magnetic resonance (MR) imaging in the histopathological examination of meningiomas. We analyzed the relationships between radiological findings on perfusion MR imaging and pathological characteristics such as origin of the tumor, mitotic activity, pathological subtype, and perifocal edema formation. The subjects were 21 surgical cases of meningioma preoperatively evaluated by perfusion MR imaging. A region of interest (ROI) was set inside of the tumor, and perifocal edema of the same size, cerebral blood volume (CBV), and cerebral blood flow (CBF) on perfusion MR and diffusion-weighted (DW) imaging were analyzed. These radiological data were evaluated in comparison with histopathological characteristics. On perfusion MR imaging, the average ratio of CBV against the contralateral side was 6.43 (1.13–20.0) and that of CBF was 7.73 (1.34–11.3). There was no significant relationship with perfusion MR imaging data, tumor volume, or perifocal edema volume. However, the large peritumoral edema group often had a higher CBV and CBF than the non-large peritumoral edema group. The skull base group had a significantly higher CBV and lower signal intensity on DW images than the non-skull base group. Signal intensity on DW images was higher in grade II or III than in grade I. Perfusion MR imaging data revealed that the higher ratio of peritumoral edema against tumor size was associated with higher blood flow and blood volume under intratumoral circulatory conditions, and that skull base meningioma had a higher blood volume than non-skull base meningioma.

A novel sulfated glycosphingolipid, SGL-1, was isolated from the ascidian Ciona intestinalis, prepared from chloroform/methanol extracts and fractionated successively on DEAE Sephadex-A25, Florisil and Iatrobeads column chromatographies. Chemical structural analysis was performed using methylation analysis, gas-liquid chromatography, combined gas-liquid chromatography-mass spectrometry, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 1H-NMR spectroscopy. This chemical structure is presented as GlcCer I6-Sulfate. The ceramide moiety was specified by t16:0, t17:0, br,t17:0, t18:0 and br,t18:0 as sphingoids, and 2-hydroxy, saturated fatty acids as represented by docosanoic and tetracosanoic acids.
