Objective: Although the benefits of carvedilol, non-cardioselective Β-blocker, were demonstrated by several studies, there were no studies which evaluated the efficacy of bisoprolol, a class of Β1-selective beta blocker, in secondary prevention of acute myocardial infarction(MI) patients who underwent percutaneous coronary intervention (PCI). Methods: Total 13,813 patients who underwent PCI were treated with carvedilol or bisoprolol at discharge in Korean Acute MI Registry (KAMIR). After 1: 2 propensity matching, 1,806 patients were enrolled as bisoprolol group and 3,612 patients as carvedilol group. The primary end point was composite of major adverse cardiac events (MACEs)which were defined as cardiac death, non-fatal MI, target vessel revascularization, and coronary artery bypass surgery. The secondary end point was defined as respective all-cause mortality, cardiac death, non-fatal MI, any revascularization or target vessel revascularization. Results: After adjustment of baseline characteristics by propensity matching, the MACEs free survival rate was not different between bisoprolol and carvedilol group. The subgroup analysis showed that cumulative incidence of MACEs was lower in bisoprolol group in patients having Killip class III or IV comparing with carvedilol group. The incidence of secondary end points was not different between two groups. Conclusions: The benefits of bisoprolol were comparable with carvedilol in secondary prevention of acute MI. The use of bisoprolol may be preferable in hemodynamically unstable acute MI patients on admission.
Early versus Late Thrombolysis in Acute Arterial Occlusion

Background: Acute arterial occlusion of extremities is defined as 14 days or less of duration after onset of symptoms for arterial occlusion. This study was designed to study the efficacy of an early thrombolysis compared with a late thrombolysis in patient with acute arterial occlusion. Methods: We identified all patients discharged from the Gwangju Veterans hospital with a diagnosis of acute arterial occlusion between 2006 and 2014. Total 72 patients received urgent catheter-directed thrmbolysis therapy using urokinase for acute arterial occlusion. The early thrombolysis group ((less than 7 days after the onset of symptoms) was 42 and the late thrombolysis group (7 to 14 days after the onset of symptoms) was 30. The primary outcome was amputation rate at 180 days and the secondary outcomes were all cause mortality at 180days and the increase of ankle brachial blood-pressure index (ABI). Results: Age (74.7 ± 9.4 vs. 75.5 ± 9.5, p=0.729) and sex (95.2% and 100% of male, p=0.225) were not different between two group. There were no significant difference in prevalence of hypertension, diabetes mellitus, dyslipidemia, smoking, peripheral artery disease, coronary artery disease. Amputation rate at 180 days was lower in early thrombolysis group (7.1% vs. 30.0%, p=0.010). The prevalence of atrial fibrillation was higher in early thrombolysis group (40.5% vs. 10.7%, p=0.031). There was no significant difference in mortality rate (16.7% vs. 16.7%, p=1.0) and the increase of ABI (0.69 ± 0.28 vs. 0.60 ± 0.36, p=0.272). In multivariable cox-regression analysis, early thrombolysis reduced the amputation rate at 180 days (HR =0.155, 95% CI=0.034-0.707, p=0.016) Conclusions: Early thrombolysis did differ greatly from late thrombolysis in preventing amputation rate in patients with acute arterial occlusion.

The occurrence of human norovirus (NoV) genogroup I (GI) and genogroup II (GII) strains was investigated in Korea. Between 2007 and 2010, 265 samples were collected from 89 Korean water source locations. NoV GI was detected in 4.5% and NoV GII in 1.5%. Samples collected in winter had the highest occurrence; 9.4% for NoV GI and 6.3% for NoV GII. NoV GI detection was highest in groundwater, with the next highest in river water and the lowest in lake water (5.9%, 5.4%, and 1.6%, respectively), and NoV GII was found only in river water. When three representative Korean basin systems (Han (H)-, Geum/Seom (G/S)-, and Nakdong (N)-river basins) were compared, both NoV genogroups were high in the G/S-, but absent in the H- river basin. The most prevalent genotypes within the GI and GII groups were GI.5 and GII.4, respectively. The NoVs found in surface water were identical to those found in patients and those found in groundwater. The NoVs appeared to be transmitted from the patient to the surface water, and then to the groundwater, suggesting a fecal-oral route of transmission. This is the first nationwide surveillance of NoV in major Korean water sources.

<P>We report a new ternary Zn<SUB>2</SUB>SnO<SUB>4</SUB> (ZSO) electron-transporting electrode of a CH<SUB>3</SUB>NH<SUB>3</SUB>PbI<SUB>3</SUB> perovskite solar cell as an alternative to the conventional TiO<SUB>2</SUB> electrode. The ZSO-based perovskite solar cells have been prepared following a conventional procedure known as a sequential (or two-step) process with ZSO compact/mesoscopic layers instead of the conventional TiO<SUB>2</SUB> counterparts, and their solar cell properties have been investigated as a function of the thickness of either the ZSO compact layer or the ZSO mesoscopic layer. The presence of the ZSO compact layer has a negligible influence on the transmittance of the incident light regardless of its thickness, whereas the thickest compact layer blocks the back-electron transfer most efficiently. The open-circuit voltage and fill factor increase with the increasing thickness of the mesoscopic ZSO layer, whereas the short-circuit current density decreases with the increasing thickness except for the thinnest one (∼100 nm). As a result, the device with a 300 nm-thick mesoscopic ZSO layer shows the highest conversion efficiency of 7%. In addition, time-resolved and frequency-resolved measurements reveal that the ZSO-based perovskite solar cell exhibits faster electron transport (∼10 times) and superior charge-collection capability compared to the TiO<SUB>2</SUB>-based counterpart with similar thickness and conversion efficiency.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2014/jpccck.2014.118.issue-40/jp509183k/production/images/medium/jp-2014-09183k_0004.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp509183k'>ACS Electronic Supporting Info</A></P>
