Background
Previous studies have shown that von Willebrand factor (VWF) increases, and a disintegrin-like and metalloproteinase with thrombospondin type-1 motifs 13 (ADAMTS13) decreases in myocardial infarction. Few studies have examined the involvement of the VWF-ADAMTS13 axis in ST-elevation myocardial infarction (STEMI) patients with atrial fibrillation (AF).
Purpose
Our aim was to investigate VWF-ADAMTS13 axis involvement in atrial fibrillation in STEMI.
Methods
The subjects of this study were participants in an observational study for investigating the difference in the pathology of thrombus retrieved from infarct-related artery between AF and sinus rhythm (SR). From June 2019 to August 2020, patients who underwent thrombus aspiration for STEMI at our hospital. Only subjects whose thrombus could be confirmed were enrolled. They were divided into two groups, the AF group, and the SR group. Serum biomarkers, including ADAMTS13 activity, and VWF were evaluated.
Results
34 patients with STEMI who were able to aspirate thrombus were enrolled in the study. They were divided into two groups: 6 patients with AF (AF group, mean age 72.5 years, 100% male) and 28 patients with SR (SR group, mean age 63.0 years, 100% male). ADAMTS13 activity was significantly lower in AF group than SR group (AF: 0.63 ± 0.14 vs. SR: 0.77 ± 0.13 U / mL, p = 0.037). There was no significant difference in VWF antigen between the two groups (AF: 251 ± 56 vs. SR: 204 ± 69%, p = 0.170). VWF/ADAMTS13 activity in AF group were significantly higher than in SR group.
Conclusion
Our study suggests an association between the VWF-ADAMTS13 axis and atrial fibrillation in STEMI. Abstract Table. Comparison of serum biomarkers

Abstract
Left ventricular (LV) pseudoaneurysm is a rare complication after postinfarction repair of ventricular septal rupture (VSR), and surgical treatment of this condition due to mycosis has rarely been reported. We report a rare case of successful surgical treatment of delayed LV pseudoaneurysm related to Candida albicans infection after repair of VSR due to myocardial infarction. A 75-year-old woman was admitted for fever and severe inflammatory reaction. Two and a half years previously, she had undergone postinfarct VSR repair and was treated for mycotic infective endocarditis due to C. albicans. Transthoracic echocardiography and computed tomography revealed a LV pseudoaneurysm (maximum transverse diameter 6.2 cm). The cause of the LV pseudoaneurysm was suspected to be infectious, and broad-spectrum antibiotic treatment was started. Fourteen days after admission, she developed acute abdominal pain and an elevated β-D-glucan level because the LV pseudoaneurysm ruptured. Emergency surgical treatment was performed with antimycotic drug therapy. The LV wall defect was reconstructed using bovine pericardium under cardiopulmonary support. Her postoperative course was good, and she was discharged to home. Echocardiography revealed no recurrence of the LV pseudoaneurysm at 4 months postoperatively. During 1 year of follow-up, the patient had been doing well without any infection or adverse event. <Learning objective: The development of a left ventricular (LV) pseudoaneurysm after repair of postinfarction ventricular septal rupture (VSR) is rare, and the cause of this condition is often unknown. Moreover, LV pseudoaneurysm due to mycosis has rarely been reported and is thought to have a poor prognosis. We report a rare case of successful surgical treatment of delayed LV pseudoaneurysm related to Candida albicans infection after repair of VSR complicating acute myocardial infarction.>

Abstract
BACKGROUND Periodic point prevalence surveys (PPSs) provide a method for assessing changes in healthcare-associated infections (HAIs) and antimicrobial use over time. Following the introduction of an antimicrobial stewardship programme at Nagoya University Hospital (Aichi, Japan) a five-year PPS study was performed to highlight any epidemiological changes. METHODS One-day PPSs were performed annually in July at Nagoya University Hospital. Data on patient characteristics, medical devices, active HAIs and antimicrobial use were collected using a standard data-collection form. RESULTS A total of 4339 patients were included. Over the five-year study period the median patient age was 62 years, median duration of hospital admission was nine days, 9% of patients had an HAI and 35.2% received at least one antimicrobial. Overall there were 406 HAIs (95% confidence interval, 369-447) with surgical site infection, pneumonia and febrile neutropenia occurring most frequently. Enterobacterales were the most common pathogens (N = 78, 28.6%) and 32.1% were third-generation cephalosporin-resistant. Meropenem was the most frequently prescribed antimicrobial for HAIs. Surgical antimicrobial prophylaxis changed drastically, with shorter durations and a marked reduction in oral cephalosporin use. However, antimicrobials for medical prophylaxis gradually increased. CONCLUSIONS This five-year PPS study shows consistent data for patient background, HAIs and causative pathogens and highlights changes in antimicrobial use during the era of the National Action Plan on Antimicrobial Resistance. To describe the epidemiology of Japanese hospitals by PPS, multicentre PPSs including in community hospitals should be performed annually.

Abstract
Awareness of variations in the hepatic vasculature and biliary system is extremely important for avoiding iatrogenic injury in upper-abdominal surgery. The objective of this study is to describe a rare case of abnormal vascular and biliary structures in the hepatocystic triangle (HCT) (the modern Calot's triangle). During anatomical dissection of the celiac trunk (CT) in an old man, the authors observed the presence of a hepatosplenic trunk arising from the CT and bifurcating into common hepatic and splenic arteries. The common hepatic artery divided into hepatic artery proper and gastroduodenal artery. The presence of accessory right hepatic artery (ARHA) arising from the superior mesenteric artery was also notable. The aberrant artery ascended retropancreatically ventral to the splenic vein, then posterolaterally to the portal vein before termination into the right hepatic lobe in the HCT. Within this triangle, there was an aberrant bile duct originating in the right hepatic lobe and ending in the common hepatic duct. This accessory duct crossed the ARHA and an associated branch (the cystic artery). There is no known previous report on the co-existence of an AHAR and an aberrant bile duct within the HCT, in addition to the hepatosplenic trunk. The clinical implications of the current case are addressed in discussion.

Abstract
Either the triggering of large earthquakes on a fault hosting aseismic slip or the triggering of slow slip events (SSE) by passing seismic waves involve seismological questions with important hazard implications. Just a few observations plausibly suggest that such interactions actually happen in nature. In this study we show that three recent devastating earthquakes in Mexico are likely related to SSEs, describing a cascade of events interacting with each other on a regional scale via quasi-static and/or dynamic perturbations across the states of Guerrero and Oaxaca. Such interaction seems to be conditioned by the transient memory of Earth materials subject to the "traumatic" stress produced by seismic waves of the great 2017 (Mw8.2) Tehuantepec earthquake, which strongly disturbed the SSE cycles over a 650 km long segment of the subduction plate interface. Our results imply that seismic hazard in large populated areas is a short-term evolving function of seismotectonic processes that are often observable.

Abstract
We evaluated the cardiac function recovery following skeletal myoblast cell-sheet transplantation and the long-term outcomes after applying this treatment in 23 patients with ischemic cardiomyopathy. We defined patients as “responders” when their left ventricular ejection fraction remained unchanged or improved at 6 months after treatment. At 6 months, 16 (69.6%) patients were defined as responders, and the average increase in left ventricular ejection fraction was 4.9%. The responders achieved greater improvement degrees in left ventricular and hemodynamic function parameters, and they presented improved exercise capacity. During the follow-up period (56 ± 28 months), there were four deaths and the overall 5-year survival rate was 95%. Although the responders showed higher freedom from mortality and/or heart failure admission (5-year, 81% versus 0%; p = 0.0002), both groups presented an excellent 5-year survival rate (5-year, 93% versus 100%; p = 0.297) that was higher than that predicted using the Seattle Heart Failure Model. The stepwise logistic regression analysis showed that the preoperative estimated glomerular filtration rate and the left ventricular end-systolic volume index were independently associated with the recovery progress. Approximately 70% of patients with “no-option” ischemic cardiomyopathy responded well to the cell-sheet transplantation. Preoperative renal and left ventricular function might predict the patients’ response to this treatment.

Abstract
It has been reported that the cardiovascular response in the supine position is different from that in the sitting position. However, there are few reports on the effects of posture on cerebral oxygenation during exercise. Cycling exercises change oxygenated hemoglobin (O2Hb) and deoxygenated hemoglobin (HHb) levels in motor-related areas. Therefore, this study compared O2Hb levels at motor-related areas during recumbent versus supine cycling. Eleven healthy young male performed a 30-min cycling exercise protocol at 50% of the maximal oxygen uptake (VO2 max) in the recumbent and supine positions. Near-infrared spectroscopy (NIRS) was used to measure exercise-induced O2Hb and HHb changes in the right (R-PMA) and left premotor areas (L-PMA), supplementary motor area (SMA), and primary motor cortex (M1). In R-PMA, L-PMA and SMA, the O2Hb obtained during supine cycling was significantly higher than that during recumbent cycling (R-PMA, 0.031 ± 0.01 vs. 0.693 ± 0.01; L-PMA, 0.027 ± 0.01 vs. 0.085 ± 0.013; SMA, 0.041 ± 0.011 vs. 0.076 ± 0.008 mM·cm, recumbent vs. supine position; p < 0.05). These results suggest that supine cycling exercise increases R-PMA, L-PMA, and SMA O2Hb levels in healthy young men.

Abstract
Abstract
Background
Peri-stent contrast staining (PSS) has been reported to be associated with very late stent thrombosis.
The aims of this study was to compare the occurrence rate of PSS between second generation drug-eluting stents (2nd DES) and third generation drug-eluting stents (3rd DES), and to identify clinical characteristics associated with PSS.
Methods and results
This study comprised 1899 patients with 2493 de novo lesions treated with 2nd or 3rd DES from October 2015 to September 2018. Follow-up angiography was available for 1883 lesions (75.5%). There were 725 patients with 968 lesions treated with 2nd DES, and 716 patients with 915 lesions treated with 3rd DES. The occurrence of PSS, types of PSS, and VLST related to PSS were compared between 2nd and 3rd DES implantation. Mean follow-up period was 30±12 months. The occurrence rate of PSS and segmental type of PSS were similar between two groups (2nd DES vs. 3rd DES, 1.5% vs. 1.7%, p=0.73, 47% vs. 50%, p=0.85, and respectively). The VLST related to PSS occurred in only one case in 3rd DES group. (0% vs. 6.3%, p=0.33).
Conclusion
The occurrence rate of PSS and clinical course were similar between 2nd and 3rd DES.

Abstract
Abstract
Introduction
The gold standard of sleep measurement has been laboratory polysomnography (PSG). However, electrodes and cables can cause discomfort, and exposure to an unfamiliar environment can cause the “first-night effect.” Difficulty falling asleep or maintaining sleep, poor sleep quality, and nightmares are some of the key clinical symptoms observed among individuals with psychiatric disorders. Those suffering from sleep disorders often present with symptoms of discontent with regard to sleep quality, timing, and quantity, and these symptoms have an adverse impact on function and quality of life. A minimally invasive technique would be preferable in patients with psychiatric disorders, who tend to be sensitive to environmental change. Accordingly, we evaluated the performance of a single-channel electroencephalography (EEG)-based sleep monitoring system in patients with psychiatric disorders.
Methods
Fifty-nine patients undergoing PSG were enrolled in this study. Single-channel EEG sleep monitoring was performed simultaneously with PSG. PSG and the EEG recordings were used to evaluate sleep parameters, such as total sleep time (TST), sleep efficiency, rapid eye movement (REM) sleep, light sleep (stages N1 and N2), and deep sleep (stage N3). Correlation analysis was used to evaluate the agreement on sleep parameters and attributing factors to the inaccuracies of the single-channel EEG recording.
Results
TST, sleep efficiency, REM sleep duration, and non-REM sleep duration of the single-channel EEG-based sleep monitoring showed a significant correlation with those of PSG. Lower sleep efficiency, a decrease in REM sleep, and increases in waking after sleep onset, arousal index, and apnea/hypopnea index were associated with the difference of sleep parameters between the two methods.
Conclusion
Among patients with psychiatric disorders who are sensitive to environmental change single-channel EEG sleep monitoring would be a useful technique to objectively evaluate sleep quality.

Abstract
The excitation functions for quasielastic scattering of ^{22}Ne+^{248}Cm, ^{26}Mg+^{248}Cm, and ^{48}Ca+^{238}U are measured using a gas-filled recoil ion separator. The quasielastic barrier distributions are extracted for these systems and are compared with coupled-channel calculations. The results indicate that the barrier distribution is affected dominantly by deformation of the actinide target nuclei, but also by vibrational or rotational excitations of the projectile nuclei, as well as neutron transfer processes before capture. From a comparison between the experimental barrier distributions and the evaporation residue cross sections for Sg (Z=106), Hs (108), Cn (112), and Lv (116), it is suggested that the hot fusion reactions take advantage of a compact collision, where the projectile approaches along the short axis of a prolately deformed nucleus. A new method is proposed to estimate the optimum incident energy to synthesize unknown superheavy nuclei using the barrier distribution.

Abstract
Abstract
Ten laboratories collaboratively studied a liquid chromatographic (LC) method for the determination of propyl, octyl, and dodecyl gallate (PG, OG, and DG, respectively), 2,4,5-trihydroxybutyrophenone (THBP), ferf-butylhydroquinone (TBHQ), nordihydroguaiaretic acid (NDGA), 2- and 3-tert-butyl-4- hydroxyanisole (BHA), 2,6-di-ferf-butyl-4-hydroxymethylphenol (lonox-100), and 3,5-di-terf-butyl-4- hydroxytoluene (BHT) in butter oil. The 10 samples analyzed were spiked in matched pairs at about 100,50, and 10 μg/g. In the method studied, antioxidants are extracted as in AOAC LC method 983.15, but different LC eluants are used to separate the 9 antioxidants. Results from 1 laboratory were rejected as not valid and were not included in any calculations. For the remaining 9 laboratories, the overall mean recoveries for PG, THBP, TBHQ, NDGA, BHA, OG, lonox, BHT, and DG were 100.9, 97.8,103.4,95.4, 97.4,93.6,95.5,79.0, and 96.2%, respectively. The overall reproducibility relative standard deviations were 8.55,17.4,25.6,14.5,6.60, 9.64,10.8,11.4, and 7.35%, respectively. The method was adopted first action by AOAC International as a modification of AOAC method 983.15.
