Background:
and Purpose We aimed to evaluate whether early versus late initiation of direct oral anticoagulant (DOAC) after acute ischemic stroke (AIS) yields different safety and efficacy outcomes in Asian versus non-Asian patients.
Methods:
We analyzed Early versus Late initiation of direct oral Anticoagulants in post-ischaemic stroke patients with atrial fibrillatioN (ELAN) trial data from 2,013 AIS patients with atrial fibrillation (AF) randomized to early (≤48 hours for minor/moderate stroke, 6–7 days for major stroke) or late DOAC initiation (3–4 days for minor ischemic stroke, 6–7 days for moderate ischemic stroke, 12–14 days for major ischemic stroke). Patients were categorized by region as Asian (Japan and India) or non-Asian. The primary outcome was a composite of major extracranial bleeding, symptomatic uncerintracranial hemorrhage (SICH), recurrent ischemic stroke, systemic embolism (SE), or vascular death at 30 days (trial registration: ClinicalTrials.gov number, NCT03148457).
Results:
Among 1,975 patients, 245 were Asian (192 from Japan and 53 from India) and 1,730 were non-Asian. The primary outcome occurred in 6.5% of Asian patients (4.8% early vs. 8.3% late) and 3.1% of non-Asian patients (2.7% vs. 3.6%) (p<0.01). Higher rates of recurrent ischemic stroke (4.1% [2.4% vs. 5.8%] vs. 1.7% [1.3% vs. 2.1%], p=0.02) and SE (2.0% [0.8% vs. 3.3%] vs. 0.5% [0.4% vs. 0.6%], p=0.02) accounted for this difference. No significant differences were observed in major extracranial bleeding, SICH, recurrent ischemic stroke, SE, or vascular death. No significant interaction was observed between region and treatment allocation.
Conclusions
Although Asian patients had worse baseline profiles and outcomes, treatment effects did not differ by region, supporting the generalizability of early DOAC initiation in Asian AIS patients without region-specific timing modifications.

Background: Rotavirus vaccines were introduced in Japan in November 2011. We evaluated the subsequent reduction of the health-care burden of rotavirus gastroenteritis.
Methods: We conducted active surveillance for rotavirus gastroenteritis among children under 5 years old before and after the vaccine introduction. We surveyed hospitalization rates for rotavirus gastroenteritis in children in Tsu City, Mie Prefecture, Japan, from 2007 to 2015 and surveyed the number of outpatient visits at a Tsu City clinic from 2010 to 2015. Stool samples were obtained for rotavirus testing and genotype investigation. We assessed rotavirus vaccine coverage for infants living in Tsu City.
Results: In the pre-vaccine years (2007-2011), hospitalization rates for rotavirus gastroenteritis in children under 5 years old were 5.5, 4.3, 3.1 and 3.9 cases per 1000 person-years, respectively. In the post-vaccine years (2011-2015), the rates were 3.0, 3.5, 0.8 and 0.6 cases per 1000 person-years, respectively. The hospitalization rate decreased significantly in the 2013-2014 and 2014-2015 seasons compared to the average of the seasons before vaccine introduction (p < 0.0001). In one pre-vaccine year (2010-2011), the number of outpatient visits due to the rotavirus infection was 66. In the post-vaccine years (2011-2015), the numbers for each season was 23, 23, 7 and 5, respectively. The most dominant rotavirus genotype shifted from G3P[8] to G1P[8] and to G2P[4]. The coverage of one dose of rotavirus vaccine in Tsu City was 56.5% in 2014.
Conclusion: After the vaccine introduction, the hospitalization rates and outpatient visits for rotavirus gastroenteritis greatly decreased.

Objective:
There have been a few reports on the specificity of the meridians and Acupuncture-points. In order to identify the specific effects of the meridians and Acupuncture-points, the functional relations between “the gallbladder Meridian and gallbladder” were investigated using the gallbladder's form as an index.
Materials and Methods:
Ten healthy male adult volunteers participated in the experiments in fasting conditions. The target organ was the gallbladder, and its form was measured with the ultrasonic diagnostic apparatus (Toshiba SSA-90A). The images of the gallbladder form were taken at the point when the major long axis of the cross-section of the gallbladder reached the peak. The cross-sectional area of the gallbladder was measured with the image analyzer. The measurement of the gallbladder form was conducted after 15 minutes lying on the back, taking images for 10 minutes before stimulation, for 30 minutes during and after stimulation, every two to five minutes. The acupuncture stimulation was given at the points of G34, G36, G37, G40 and G44 on the right side of the body. After getting the deqi, 1 minute of sparrow pecking needle technique and 1 minute of leaving needle technique were conducted three times. The effect of the G40 under the egg yolk loading were also investigated.
Results:
1) The stimulation of the G34, G36, G37, and G44 showed no effects on the gallbladder form. 2) The stimulation of the G40 caused the distension of the gallbladder form. 3) The stimulation of the G40 showed the suppressive effect on the contraction of the gallbladder due to the load of egg yolk.
As described above, the results of this study showed that there is an acupuncture-point on the gallbladder meridian to cause the distension of the gallbladder specifically. It suggests the existence of the specificity of acupuncture-point.
