Abstract
Background Extracorporeal cardiopulmonary resuscitation (ECPR) using venoarterial extracorporeal membrane oxygenation is performed for out-of-hospital cardiac arrest; however, it is associated with a risk of several complications. Objective To investigate whether the fluoroscopy equipment was removed from the emergency department (ED) and whether it would be beneficial to transport the patient to the fluoroscopy room to reduce vascular complications without affecting the induction time. Methods This single-center, retrospective, before-and-after analysis was conducted at a tertiary emergency medical center and included 59 patients who underwent ECPR for out-of-hospital cardiac arrest between May 2017 and March 2022. The patients were divided into two groups: those who underwent cannulation in the ED without fluoroscopy (ED-ECPR group) and those who were transferred directly from the ED to the cardiac angiography room (ECPR call group). Results The rate of vascular complications associated with ECPR was significantly lower in the ECPR group than in the ED-ECPR group (40.6 % [14/32] vs. 10 % [2/20], respectively; p = 0.014). The duration from ED arrival to venoarterial extracorporeal membrane oxygenation initiation was similar in the two groups (median: 23.0 min in the ED-ECPR group vs. 25.5 min in the ECPR call group, p = 0.71). Results adjusted for confounding factors showed that performing ECPR under fluoroscopy was a consistent and independent element of vascular complication rates (adjusted odds ratio: 9.92, 95 % confidence interval: 2.04 to 81.2, p = 0.011). Conclusions Fluoroscopy-guided ECPR can significantly reduce the incidence of vascular complications even if the ED and fluoroscopy room are far apart. However, no significant difference was observed in the time required to establish ECPR in the cardiac catheterization laboratories.

Abstract
PURPOSE The effect of head rotation on supraglottic airway (SGA) oropharyngeal leak pressure (OPLP) has not been well elucidated. The aim of this study was to help clarify which SGA device provides higher OPLP at head-rotated position. METHODS Patients who underwent elective surgery under general anesthesia were enrolled and randomly divided into laryngeal mask airway (LMA®) ProSeal™ and i-gel® groups. The allocated SGA device was inserted under anesthesia. The primary outcome was OPLP, and secondary outcomes were ventilation score, expiratory tidal volume, and maximum pressure under volume-controlled ventilation (VCV) with an inspiratory tidal volume of 10 mL·kg-1 ideal body weight and fibreoptic view of the vocal cords at 0°, 30°, and 60° head rotation. RESULTS Data from 78 and 76 patients were analyzed in the LMA ProSeal and i-gel groups, respectively. The mean (standard deviation) OPLP of the LMA ProSeal was significantly higher than that of the i-gel at the 60° head-rotated position (LMA ProSeal, 20.4 [6.5] vs i-gel, 16.9 [7.8] cm H2O; difference in means, 3.6; adjusted 95% confidence interval, 0.5 to 6.6; adjusted P = 0.02, adjusted for six comparisons). The maximum pressure under VCV at 60° head rotation was significantly higher in the LMA ProSeal group than in the i-gel group. The expiratory tidal volume of the LMA ProSeal did not significantly change with head rotation and was significantly higher than that of the i-gel at 60° head rotation. Ventilation score, fibreoptic view of the vocal cords, and complications were not significantly different between the ProSeal and i-gel groups. CONCLUSIONS The LMA ProSeal provides higher OPLP than the i-gel at a 60° head-rotated position under general anesthesia.

Abstract
The supraglottic airway (SGA) is widely used. I-gel Plus is a next-generation i-gel with some improvements, including facilitation of fiberoptic tracheal intubation (FOI). To compare the performance of i-gel Plus and standard i-gel as conduits for FOI, a Thiel-embalmed cadaveric study was conducted. Twenty-two anesthesiologists were enrolled as operators in Experiment 1. The i-gel Plus and standard i-gel were inserted into one cadaver, and the FOI was performed through each SGA. The primary outcome was time required for FOI. The secondary outcomes were the number of attempts and visual analog scale (VAS) score for difficulty in FOI. Moreover, fiberoptic views of the vocal cords in each SGA were assessed by an attending anesthesiologist using nine cadavers in Experiment 2. The percentage of glottic opening (POGO) score without fiberscope tip upward flexion and upward angle of the fiberscope tip to obtain a 100% POGO score were evaluated as secondary outcomes. The time for FOI through i-gel Plus was significantly shorter than that through standard i-gel (median (IQR), i-gel Plus: 30.3 (25.4-39.0) s, vs standard i-gel: 54.7 (29.6-135.0) s; median of differences, 24.4 s; adjusted 95% confidence interval, 3.0-105.7; adjusted P = 0.040). Although the number of attempts for successful FOI was not significantly different, the VAS score for difficulty in the i-gel Plus group was significantly lower (easier) than that in the standard i-gel group. Moreover, i-gel Plus required a significantly smaller upward angle of the fiberscope tip to obtain a 100% POGO score. FOI can be performed more easily using i-gel Plus than using standard i-gel because of the improved fiberoptic visibility of vocal cords.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
BACKGROUND Chronic graft-versus-host disease (GVHD) is a major complication of hematopoietic stem cell transplantations. Due to fibrotic changes, patients with GVHD are at risk for difficult airway management. We encountered a case of chronic GVHD that went into a "cannot intubate, cannot ventilate" (CICV) condition after induction of general anesthesia and was managed using cricothyrotomy. CASE REPORT A 45-year-old man with uncontrolled chronic GVHD developed pneumothorax of the right lung. Thoracoscopic dissection of the adhesions, closure of the pneumostomy, and drainage under general anesthesia were planned. In the preoperative airway assessment, we concluded that using a video laryngoscope or endotracheal fiber would be sufficient to intubate the patient after sedation and that airway management after the loss of consciousness would not be difficult. Therefore, general anesthesia was induced by rapid induction; however, the patient developed difficult mask ventilation. Intubation was attempted via a video laryngoscope or bronchofiber but failed. Ventilating using a supraglottic instrument was difficult. The patient was evaluated to have a CICV condition. Thereafter, because of a rapid decrease in oxygen saturation (SpO2) and bradycardia, a cricothyrotomy was performed. Subsequently, ventilation became adequate, SpO2 increased immediately and drastically, and respiration and circulatory dynamics recovered. CONCLUSIONS We believe that anesthesiologists should practice, prepare, and simulate airway emergencies that can be experienced during surgery. In this case, we recognized that skin sclerosis in the neck and chest could lead to CICV. It may be suitable for airway management of scleroderma-like patients to select conscious intubation with a bronchoscope as a first choice.

Abstract
Remimazolam is a short-acting benzodiazepine that was approved for clinical use in 2020. We report three patients who underwent surgery for cerebral and spinal cord tumors, in whom transcranial electrical stimulation-motor-evoked potential (TES-MEP) was successfully monitored under general anesthesia with remimazolam. During total intravenous anesthesia with propofol at a target concentration of 2.7 - 3.5 µg/mL and 0.1 - 0.35 µg/kg/min of remifentanil, delayed awakening, bradycardia, and hypotension during propofol anesthesia were expected in all three cases. With patient safety as the top priority, we considered changing the anesthetic agent. Propofol was replaced with remimazolam at a loading dose of 12 mg/kg/h for a few seconds (case 3), followed by 1 mg/kg/h for maintenance (cases 1-3). TES-MEP was recorded during propofol and remimazolam administration in all three patients. Amplitudes of TES-MEP during anesthesia with propofol and remimazolam were 461.5 ± 150 µV and 590.5 ± 100.9 µV, 1542 ± 127 µV and 1698 ± 211 µV, and 581.5 ± 91.3 µV and 634 ± 82.7 µV sequentially from Case 1. Our findings suggest that intraoperative TES-MEP could be measured when anesthesia was managed with remimazolam at 1 mg/kg/h.

Abstract
Background Amyotrophic lateral sclerosis (ALS) is known to cause generalized muscle atrophy and respiratory complications. Anesthetic agents and methods for patients with ALS are extremely important because they critically influence postoperative outcomes. In this clinical case, we mainly used remimazolam for safe anesthesia management. Case presentation A 66-year-old man had a gradual onset of numbness and weakness in his extremities over 2 years. He was diagnosed with ALS after the appearance of dysarthria and restrictive ventilation disorder. Due to the rapid progression of respiratory dysfunction, the patient was placed on artificial respiration, and a tracheostomy was planned. General anesthesia was induced with remimazolam (6 mg/kg/h) and remifentanil (0.5 μg/kg/min). Tracheal intubation was performed without muscle relaxants, followed by total intravenous anesthesia (TIVA) with continuous administration of remimazolam 0.8–1.2 mg/kg/h and remifentanil 0.3–0.5 μg/kg/min. At the end of the surgery, the anesthetic effect of remimazolam was reversed with 0.4 mg of flumazenil. The patient was discharged from the operating room with stable breathing, and changes to preoperative ventilator settings were not necessary. Conclusions We safely performed tracheostomy for a patient with ALS using remimazolam during general anesthesia.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Abstract
Background Physicians have had to perform numerous extubation procedures during the prolonged coronavirus disease 2019 (COVID 19) pandemic. Future pandemics caused by unknown pathogen may also present a risk of exposure to infectious droplets and aerosols. Aim This study evaluated the ability of a newly developed aerosol barrier, “Extubation-Aerosol (EA)-Shield” to provide maximum protection from aerosol exposure during extubation via an aerosolised particle count and high-quality visualisation assessments. Methods We employed a cough model having parameters similar to humans and used micron oil aerosol as well as titanium dioxide as aerosol tracers. Aerosol barrier techniques employing a face mask (group M) and EA-Shield (group H) were compared. Findings The primary outcome was the difference in the number of particles contacting the physician's face before and after extubation. The maximum distances of aerosol dispersal after extubation were measured as the secondary outcomes. All aerosolised particles of the two tracers were significantly smaller in group H than in group M (p < 0.05). In addition, the sagittal and axial maximum distances and sagittal areas of aerosol dispersal for 3, 5, and 10 s after extubation were significantly smaller in group H than in group M (p < 0.05). Conclusion This model indicates that EA-Shield could be highly effective in reducing aerosol exposure during extubation. Therefore, we recommend using it as an aerosol barrier when an infectious aerosol risk is suspected.

Abstract
Purpose The aim of this study was to compare aerosol exposure with or without an aerosol box in a pressurized/depressurized room during aerosol-generating procedures using an experimental model. Methods Cake flour (aerosol model) was expelled from an advanced life support training mannequin. The primary outcome measure was the number of 0.3–10 µm-sized particles at three locations corresponding to the physician, medical staff, and environmental aerosol exposure levels. The aerosol dispersion was visualized using a high-resolution video. The number of expelled particles was measured after artificial coughing during simulated tracheal intubation and extubation in four situations, with or without an aerosol box in a pressurized or depressurized room (≤ 2.5 Pa). Results The particles arising from tracheal intubation at the three positions in the four groups differed significantly in size (p < 0.05). The sizes of particles arising from extubation at the physicians’ and medical staff’s faces in the four groups differed significantly in size (p < 0.05). Post hoc analysis showed that the counts of all particles at the three positions were significantly lower in the depressurized room with an aerosol box than in the pressurized room without an aerosol box during tracheal intubation (p < 0.05 at three positions) and extubation (p < 0.05) at the physician’s and medical staff’s positions). Visual assessments supported these results. Conclusion The aerosol box decreased the exposure of the aerosol to the physician, medical staff, and environment during aerosol-generating procedures in the depressurized room only.

Abstract
BACKGROUND Traumatic brain injury (TBI) initiates immune responses involving infiltration of monocyte-derived macrophages (MDMs) in the injured brain tissue. These MDMs play a key role in perioperative neurocognitive disorders (PNDs). We tested the hypothesis that preanesthetic treatment with dexmedetomidine (DEX) could suppress infiltration of MDMs into the hippocampus of TBI model mice, ameliorating PND. METHODS We first performed bone marrow transplantation from green fluorescent protein-transgenic mice to C57BL/6 mice to identify MDMs. We used only male mice for homogeneity. Four weeks after transplantation, a controlled cortical impact model of TBI was created using recipient mice. Four weeks after TBI, mice received pretreatment with DEX before general anesthesia (GA). Mice performed the Barnes maze test (8-12 mice/group) 2 weeks after GA and were euthanized for immunohistochemistry (4-5 mice/group) or immunoblotting (7 mice/group) 4 weeks after GA. RESULTS In Barnes maze tests, TBI model mice showed longer primary latency (mean difference, 76.5 [95% confidence interval, 41.4-111.6], P < .0001 versus Naïve), primary path length (431.2 [98.5-763.9], P = .001 versus Naïve), and more primary errors (5.7 [0.62-10.7], P = .017 versus Naïve) than Naïve mice on experimental day 3. Expression of MDMs in the hippocampus was significantly increased in TBI mice compared to Naïve mice (2.1 [0.6-3.7], P = .003 versus Naïve). Expression of monocyte chemotactic protein-1 (MCP1)-positive areas in the hippocampus was significantly increased in TBI mice compared to Naïve mice (0.38 [0.09-0.68], P = .007 versus Naïve). Immunoblotting indicated significantly increased expression of interleukin-1β in the hippocampus in TBI mice compared to Naïve mice (1.59 [0.08-3.1], P = .035 versus Naïve). In contrast, TBI mice pretreated with DEX were rescued from these changes and showed no significant difference from Naïve mice. Yohimbine, an α2 receptor antagonist, mitigated the effects of DEX (primary latency: 68.3 [36.5-100.1], P < .0001 versus TBI-DEX; primary path length: 414.9 [120.0-709.9], P = .0002 versus DEX; primary errors: 6.6 [2.1-11.2], P = .0005 versus TBI-DEX; expression of MDMs: 2.9 [1.4-4.4], P = .0001 versus TBI-DEX; expression of MCP1: 0.4 [0.05-0.67], P = .017 versus TBI-DEX; expression of interleukin-1β: 1.8 [0.34-3.35], P = .01 versus TBI-DEX). CONCLUSIONS Preanesthetic treatment with DEX suppressed infiltration of MDMs in the hippocampus and ameliorated PND in TBI model mice. Preanesthetic treatment with DEX appears to suppress infiltration of MDMs in the hippocampus and may lead to new treatments for PND in patients with a history of TBI.

Abstract
BACKGROUND Epidural tunneling could help with prolonged catheterization and be effective in preventing infection and dislodgement. However, epidural tunneling techniques carry a risk of catheter shear or needlestick injuries. AIMS This study aimed to examine the safety of our epidural tunneling technique in terms of catheter shear. METHODS This study was designed as a double-blinded, single-crossover, in vitro study. Each of the operators performed two techniques to create a subcutaneous tunnel. We compared outcomes between the control tunneling technique (group C) and our improved technique (group I). Microscopic findings of catheter shear were assessed as the primary outcome. Secondary outcomes included the tension and displacement required to break the epidural catheter and the frequency of catheter breakage due to catheter shear. Data were analyzed using the Fisher's exact test and Mann-Whitney U test. A p-value of <.05 was considered statistically significant. RESULTS Ten catheters were assessed in each group. The frequency of catheter shear was 10% in group I and 90% in group C (odds ratio, 0.019; 95% confidence interval [CI], 0.01-0.31; p < .001). The frequency of catheter breakage due to catheter shear was significantly lower in group I (0%) than in group C (80%; p < .001). The mean tension and displacement required to break the catheter were significantly higher in group I than in group C (4.13 ± 0.37 N vs. 3.14 ± 1.00 N; mean difference, 0.99 N; 95% CI, 0.25-1.73 N; p = .013 and 222 ± 59.9 mm vs. 122 ± 77.7 mm; mean difference, 100 mm; 95% CI, 34.1-165 mm; p = .005). CONCLUSIONS Our improved epidural tunneling technique, which was designed for pediatric cases, could reduce the risk of catheter shear.

Abstract
BACKGROUND Second-generation supraglottic airway (SGA) devices are useful for airway management during positive pressure ventilation in general anesthesia and emergency medicine. In some clinical settings, such as the anesthetic management of awake craniotomy, SGAs are used in the head-rotated position, which is required for exposure of the surgical field, although this position sometimes worsens the efficiency of mechanical ventilation with SGAs. In this study, we investigated and compared the influence of head rotation on oropharyngeal leak pressures (OPLP) of the i-gel and LMA® Supreme™, which are second-generation SGA devices. METHODS Patients who underwent elective surgery under general anesthesia were enrolled in this study and randomly divided into i-gel or LMA Supreme groups. After induction of anesthesia with muscle relaxation, the i-gel or LMA Supreme was inserted according to computerized randomization. The primary outcome was the OPLP at 0°, 30°, and 60° head rotation. The secondary outcomes were the maximum airway pressure and expiratory tidal volume when patients were mechanically ventilated using a volume-controlled ventilation mode with a tidal volume of 10 mL/kg (ideal body weight), ventilation score, and fiber-optic views of vocal cords. RESULTS Thirty-four and 36 participants were included in the i-gel and LMA Supreme groups, respectively. The OPLPs of the i-gel and LMA Supreme significantly decreased as the head rotation angle increased (mean difference [95% confidence interval], P value: i-gel; 0° vs 30°: 3.5 [2.2-4.8], P < .001; 30° vs 60°: 2.0 [0.6-3.5], P = .002; 0° vs 60°: 5.5 [3.3-7.8], P < .001, LMA Supreme; 0° vs 30°: 4.1 [2.6-5.5], P < .001; 30° vs 60°: 2.4 [1.1-3.7], P < .001; 0° vs 60°: 6.5 [5.1-8.0], P < .001). There were statistically significant differences in expiratory tidal volume and ventilation score between 0° and 60° in the i-gel group and in ventilation score between 30° and 60° in the LMA Supreme group. There was no statistically significant difference between the 2 devices in all outcome measures. The incidences of adverse events, such as hoarseness or sore throat, were not significantly different between i-gel and LMA Supreme. CONCLUSIONS Head rotation to 30° and 60° reduces OPLP with both i-gel and LMA Supreme. There is no difference in OPLP between i-gel and LMA Supreme in the 3 head rotation positions.

Abstract
BACKGROUND Remimazolam is a benzodiazepine receptor agonist with an ultra-short-acting anesthetic effect. We used remimazolam for anesthesia in a patient with myotonic dystrophy type 1 who underwent endoscopic retrograde cholangiopancreatography (ERCP). CASE PRESENTATION A 58-year-old woman received ERCP under general anesthesia. She had impaired respiratory function due to myotonic dystrophy type I and was at a risk of respiratory complications after anesthesia. General anesthesia was induced with remimazolam 12 mg/kg/h, remifentanil 0.1 μg/kg/min and rocuronium 15 mg, followed by tracheal intubation and maintained with remimazolam 0.8-1.0 mg/kg/h. At the end of anesthesia, we injected sugammadex 150 mg and flumazenil 0.2 mg, allowing smooth and clear emergence from anesthesia. She was discharged from the hospital without any respiratory problems on postoperative day 5. CONCLUSIONS Remimazolam was safe to use for general anesthesia in a patient with myotonic dystrophy type 1 undergoing ERCP.

Abstract
Background Trigger point blocks are now widely practiced, especially in pain treatment. Among the complications of lumbar trigger point injection, reports of medically induced kidney injury are very rare, and diagnosis during emergency treatment is rare. Case presentation A 78-year-old woman on antiplatelet medication following a stroke was diagnosed with treatable type A aortic dissection at another hospital after undergoing lumbar trigger point injection. On arrival at our hospital, there were no signs of hemodynamic deterioration. Additional careful medical re-interview and ultrasonography by anesthesiologists enabled a definitive diagnosis of acute kidney damage and hematoma caused by lumbar trigger point injection, and aortic dissection surgery was abandoned. Conclusion This clinical case demonstrates the importance of awareness of potential kidney injury and hematoma during lumbar trigger point injection.

Abstract
Background Myotonic dystrophy is a disorder affecting multiple organs including skeletal muscles and causes respiratory failure. We describe a patient who developed respiratory failure, with delayed diagnosis of myotonic dystrophy type 1 as the cause. Case presentation A 62-year-old woman developed acute onset of dyspnea after showing hypertension and tachycardia and was transported to our hospital. On arrival at our institution, SpO2 was 80% with a non-rebreather mask. With a diagnosis of acute phase heart failure, she underwent tracheal intubation. However, weaning from the respirator was difficult in the intensive care unit (ICU). A detailed interview revealed that her brother was affected with myotonic dystrophy type 1. She was also diagnosed with myotonic dystrophy type 1 by a genetic test. Conclusions Taking a careful past and family history and prompt genetic testing is required on suspicion of neuromuscular diseases in a patient with respiratory failure by an unknown cause.

Abstract
Background Genetic factors such as single-nucleotide polymorphisms (SNPs) play a key role in the development of postoperative nausea and vomiting (PONV). However, previous findings are not widely applicable to different populations because of population-specific genetic variation. We developed a Japanese-specific DNA microarray for high-throughput genotyping. The aim of the current study was to identify SNPs associated with PONV on a genome-wide scale using this microarray in a sample of Japanese surgical patients. Methods Associations between 659,636 SNPs and the incidence of PONV 24 h after surgery in a limited sample of 24 female patients were assessed using the microarray. After imputation of genotypes at 24,330,529 SNPs, 78 SNPs were found to be associated with the incidence of PONV. We chose 4 of the 78 SNPs to focus on by in silico functional annotation. Finally, we genotyped these 4 candidate SNPs in 255 patients using real-time PCR to verify association with the incidence of PONV. Results The T > C variant of rs11232965 in the long non-coding RNA MIR4300HG was significantly associated with reduced incidence of PONV among genotypes and between alleles (p = 0.01 and 0.007). Conclusions We identified a novel SNP (rs11232965) in the long non-coding RNA MIR4300HG that is associated with PONV. The rs11232965-SNP variant (T > C) is protective against the incidence of PONV. Trial registration This study was registered at the UMIN Clinical Trials Registry (Identifier: UMIN000022903, date of registration: June 27, 2016, retrospectively registered.

Abstract
The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on Impactor. The impact produced an artificial crater with a diameter >10 meters, which has a semicircular shape, an elevated rim, and a central pit. Images of the impact and resulting ejecta were recorded by the Deployable CAMera 3 for >8 minutes, showing the growth of an ejecta curtain (the outer edge of the ejecta) and deposition of ejecta onto the surface. The ejecta curtain was asymmetric and heterogeneous and it never fully detached from the surface. The crater formed in the gravity-dominated regime; in other words, crater growth was limited by gravity not surface strength. We discuss implications for Ryugu's surface age.

Abstract
Abstract
Background
The values of n-3 and n-6 polyunsaturated fatty acids (PUFAs) like low eicosapentaenoic acid (EPA) /arachidonic acid (AA) ratio are known to be associated with cardiovascular events, however their relationship with coronary plaque vulnerability in acute myocardial infarction (AMI) is not revealed.
Purpose
We evaluated the relationship between n-3 and n-6 PUFAs and coronary plaque vulnerability assessed by optical coherence tomography (OCT) in AMI patients.
Methods
We investigated 79 AMI lesions (51 ST elevated myocardial infarction (STEMI) lesions and 28 non-STEMI lesions) that had undergone emergency percutaneous coronary intervention using OCT. Coronary plaque characteristics by OCT were compared with n-3 and n-6 PUFAs values which were measured on admission.
Results
Of all AMI lesions (n=79), 43 thin-cap fibroatheroma (TCFA) and 35 plaque rapture (PR) were detected by OCT. Lesions with TCFA had no significant relationship with n-3 and n-6 PUFAs values, whereas lesion with PR had significantly lower EPA values than those without (55.8±29.5 vs 74.3±37.1 μg/ml, p=0.018). Median low-density lipoprotein (LDL) cholesterol value was 117 (98–137) mg/dl and sub-analysis in patients who had lower LDL cholesterol values than median (n=39) revealed that EPA values were significantly lower in lesions with TCFA (56.3±30.9 vs 85.3±47.7 μg/ml, p=0.03). In STEMI patients, the values of EPA and EPA/AA ratio were significantly lower in lesions with TCFA (EPA: 55.5±22.8 vs 80.8±46.1 μg/ml, p=0.01; EPA/AA ratio: 0.34±0.16 vs 0.50±0.36, p=0.03). STEMI patients who had lower LDL cholesterol values <114 mg/dl of median (n=26), the values of EPA, EPA/AA ratio, and EPA+ docosahexaenoic acid (DHA) /AA ratio were significantly lower in lesions with TCFA (EPA: 51.4±20.7 vs 93.1±53.0 μg/ml, p=0.01; EPA/AA ratio: 0.37±0.16 vs 0.67±0.41, p=0.01; EPA+DHA/AA ratio: 1.13±0.41 vs 1.63±0.76, p=0.04). In STEMI patients with lower LDL cholesterol values, EPA/AA ratio positively correlated with fibrous cap thickness (Spearman, ρ=0.35, p=0.08). The cutoff value of EPA/AA ratio predicting the existence of TCFA was 0.52 (area under the curve 0.78, sensitivity 93.8%, specificity 70.0%, p=0.02).
Conclusion
This study demonstrated that n-3 and n-6 PUFAs values were associated with coronary plaque vulnerability by OCT in AMI patients, especially in STEMI. These results suggest that n-3 and n-6 PUFAs may be residual risk markers of severe acute cardiovascular events in patients with low LDL cholesterol values.

Abstract
BACKGROUND The main purposes of awake craniotomy are to minimize postoperative brain dysfunction caused by the surgical procedure and to maximize the tumor resection range. In awake craniotomy, it is important to have a good quality of awakening and to obtain patient's obedience in the awake phase. CASE PRESENTATION The patient was a 75-year-old woman with an advanced hearing impairment who was scheduled for awake craniotomy. We used a bone conduction voice amplifier before and during the awake phase and communicated with the patient smoothly. CONCLUSIONS We were able to complete awake craniotomy fully, and overcoming the deafness problem might have contributed to the patient's good outcome. This case report indicates that awake craniotomy can be performed in a patient with an advanced hearing impairment under the condition of careful anesthetic management.

Abstract
PURPOSE Temperature monitoring in the perioperative periods is important in order to avoid both hyperthermia and hypothermia. In our pilot study, we evaluated the usefulness of Bair Hugger™ temperature monitoring system (BHTMS), a forehead deep temperature monitoring system, in the neck and chest under general anesthesia. METHODS After approval from the Sapporo Medical University Research Ethics Board, 30 female patients scheduled for laparoscopic surgery were enrolled in this study. Patients were divided into three groups, depending on the attachment regions of BHTMS sensor. Temperatures obtained from the three regions and each esophageal temperature (TEso) were monitored and analyzed. RESULTS A Bland-Altman plot showed that the mean bias between temperature obtained from the neck and TEso was + 0.05 °C above TEso (2SD ± 0.35 °C), and that between temperature obtained from the chest and TEso was - 0.55 °C above TEso (2SD ± 0.55 °C). CONCLUSION By using the BHTMS sensor in the neck region, it is possible to monitor core body temperature seamlessly and with high reliability. These results may suggest that the use of BHTMS has high versatility in measuring perioperative core body temperature. TRIAL REGISTRATION This study was approved by the Sapporo Medical University Research Ethics Board (2015: No. 262-149) and registered with UMIN Clinical Trial Registry ( UMIN000016802 Registered 15 March 2015).

Abstract
The Hayabusa2 spacecraft arrived at the near-Earth carbonaceous asteroid 162173 Ryugu in 2018. We present Hayabusa2 observations of Ryugu's shape, mass, and geomorphology. Ryugu has an oblate "spinning top" shape, with a prominent circular equatorial ridge. Its bulk density, 1.19 ± 0.02 grams per cubic centimeter, indicates a high-porosity (>50%) interior. Large surface boulders suggest a rubble-pile structure. Surface slope analysis shows Ryugu's shape may have been produced from having once spun at twice the current rate. Coupled with the observed global material homogeneity, this suggests that Ryugu was reshaped by centrifugally induced deformation during a period of rapid rotation. From these remote-sensing investigations, we identified a suitable sample collection site on the equatorial ridge.

Abstract
The near-Earth carbonaceous asteroid 162173 Ryugu is thought to have been produced from a parent body that contained water ice and organic molecules. The Hayabusa2 spacecraft has obtained global multicolor images of Ryugu. Geomorphological features present include a circum-equatorial ridge, east-west dichotomy, high boulder abundances across the entire surface, and impact craters. Age estimates from the craters indicate a resurfacing age of [Formula: see text] years for the top 1-meter layer. Ryugu is among the darkest known bodies in the Solar System. The high abundance and spectral properties of boulders are consistent with moderately dehydrated materials, analogous to thermally metamorphosed meteorites found on Earth. The general uniformity in color across Ryugu's surface supports partial dehydration due to internal heating of the asteroid's parent body.

Abstract
BACKGROUND Severe abdominal pain caused by a rectus sheath hematoma (RSH) can decrease a patient's activities of daily living. A case of postoperative RSH for which a continuous rectus sheath block (RSB) was effective is reported. CASE PRESENTATION A 62-year-old woman who had no previous medical history underwent hysterectomy, total cystectomy, and ileal conduit surgery for bladder cancer under epidural and general anesthesia. She complained of severe abdominal pain 40 min after removal of the epidural catheter on postoperative day (POD) 4. Computed tomography showed an RSH on POD 12. For pain relief, an ultrasound-guided continuous RSB was performed on POD 17. After the block, the numerical rating scale (NRS) score during movement decreased immediately (from 10 to 2 or 3), and she had no further need for oral or intravenous analgesics. She was discharged from the hospital without any complications on POD 28. CONCLUSIONS Continuous RSB can be an effective technique for pain relief of postoperative RSH.

Abstract
Postoperative nausea and vomiting (PONV) is a common complication after general anesthesia. Recent studies suggested that the hippocampus is involved in PONV. Hypothesising that hippocampal dopaminergic neurons are related to PONV, we examined the comprehensive mRNA profile of the hippocampus, using a sevoflurane-treated mouse model to confirm this. This study was conducted after approval from our institutional animal ethics committee, the Animal Research Center of Sapporo Medical University School of Medicine (project number: 12-033). Eight mice were assigned to two groups: a naïve group and a sevoflurane group (Sev group). In the Sev group, four mice were anesthetised with 3.5% sevoflurane for 1 hour. Subsequently, mRNA was isolated from their hippocampal cells and RNA sequencing was performed on an Illumina HiSeq 2500 platform. Mapping of the quality-controlled, filtered paired-end reads to mouse genomes and quantification of the expression levels of each gene were performed using R software. The Rtn4rl2 gene that encodes the Nogo receptor was the most up-regulated gene in the present study. The expression levels of dopamine receptor genes and the tachykinin gene were increased by sevoflurane exposure, while the genes related to serotonin receptors were not altered by sevoflurane exposure. The expression levels of LIM-homeodomain-related genes were highly down-regulated by sevoflurane. These findings suggest that sevoflurane exposure induces dopaminergic stimulation of hippocampal neurons and triggers PONV, while neuronal inflammation caused by LIM-homeodomain-related genes is down-regulated by sevoflurane.

Abstract
A patient with Klippel-Feil syndrome had difficulties in inserting and placing an endotracheal tube under general anesthesia. Klippel-Feil syndrome, characterized by cervical vertebral fusion, scoliosis and endocardiosis, is a rare disease. Anesthesiologists should pay attention to management of anesthesia in airway troubles. A 53-year-old woman diagnosed with Klippel-Feil syndrome was scheduled for general anesthesia with intubation. We tried to insert an endotracheal tube using McGRATH MAC, but it was difficult to insert and place the tube. Finally, we managed to insert a 5.5 mm endotracheal tube. The three-dimensional computed tomography (3D-CT) images after the operation, showed tracheal stenosis at the level of the fourth and fifth cervical vertebrae. In cases where airway difficulties are expected, evaluating 3D-CT images might be useful in airway management.

Abstract
We previously reported that a rotation/revolution pulverizer (NP-100) could mill a small amount of a drug (0.1 g) into nanoparticles in several minutes. In this investigation, scale up from the milligram to the kilogram scale of the nano-milling process by the rotation/revolution pulverizer was studied. Phenytoin was used as a model drug with low solubility in water. After confirming the improvement of the phenytoin bioavailability by milling to nanoparticles using NP-100, scaling parameters were evaluated using NP-100 and the middle scale model of NP-100 (ARV-3000T). A theoretical equation for the specific collisional energy was adapted for wet milling; this suggested that the relative centrifugal acceleration of revolution (revolution G) and the drug concentration in the suspension were the two most important parameters. The results obtained using NP-100 and ARV-3000T correlated well when these two parameters were identical. These results were applied to the large scale model of NP-100 (ARV-10KT), where 2 kg (1 kg x 2) of phenytoin nanoparticles were obtained in 60 min. The results from PXRD and DSC indicated that the milled phenytoin by ARV-3000T and ARV-10KT maintained its crystallinity. These results suggest nano-milling using a rotation/revolution pulverizer will be widely applicable to the development of nano-medicine.

Abstract
Postoperative cognitive dysfunction (POCD) increases morbidity and mortality. The mechanisms underlying POCD remain elusive; however, systemic responses induced by anesthesia and surgery might trigger neuroinflammation and POCD. Desflurane is a preferable volatile anesthetic agent for elderly patients because it facilitates shorter recovery from general anesthesia. The aim of this study was to determine whether quality of emergence and cognitive function in elderly patients undergoing a long duration desflurane anesthesia are better than those in the case of sevoflurane anesthesia. Forty-two patients who were older than 65 years of age and scheduled for surgery of more than 4 h in duration were enrolled in this study. Patients were randomly assigned to a desflurane anesthesia group (D group) and sevoflurane anesthesia group (S group). General anesthesia was maintained with 3.5 % desflurane (D group) and 1.0 % sevoflurane (S group). The Mini-Mental State Examination (MMSE) was used for assessing cognitive function 24 h before and after surgery. Postoperative MMSE score in the D group was significantly improved compared to that in the preoperative period. In conclusion, elderly patients undergoing desflurane anesthesia have significantly better quality of emergence and may have better cognitive function than those in elderly patients undergoing sevoflurane anesthesia.

Abstract
Edoxaban, an oral direct factor Xa inhibitor, has proven antithrombotic efficacy. In a multicenter, phase II study, 264 total hip arthroplasty (THA) patients randomly received edoxaban 15 or 30 mg once daily or enoxaparin 2000IU (20-mg) twice daily for 11-14 days. Thromboembolic event incidences were 3.8% (3/78), 2.8% (2/72), and 4.1% (3/74) for edoxaban 15-mg, 30-mg, and enoxaparin, respectively (P=1.00). Edoxaban-induced prolongation of prothrombin time, international normalized ratio, and activated partial thromboplastin time were proportional to plasma edoxaban concentration. Major or clinically relevant non-major bleeding incidences were 2.2% (2/89), 1.2% (1/85), and 2.3% (2/87) for edoxaban 15-mg, 30-mg, and enoxaparin, respectively (P=1.00). Once-daily edoxaban showed similar efficacy and safety to enoxaparin for prevention of thromboembolic events in patients undergoing THA.

Abstract
Endophytic microbes are considered as an important source of natural products. They show antibiotic, anticancer, antioxidative and antidiabetic activities. Therefore, there are many reports on the isolation and bioactivity screening of endophytic fungi from various plants including Taxus species. Taxus sumatrana (Miq.) de Laub is found in Indonesia. The objective of this study is to conduct an in vitro screening of 14 endophytic fungi isolated from Taxus sumatrana having antioxidative and alpha-glucosidase inhibitor activities. Each endophytic fungus was cultured for 7 days and the fungal mycelium and medium were extracted with methanol and ethyl acetate, respectively, to produce each extract. The antioxidative activity of each extract was tested by DPPH free radical scavenging activity and beta-carotene bleaching assays, whereas antidiabetic activity was tested based on alpha-glucosidase inhibitor activity. The screening results showed that fungal mycelia of TSC 13 had the best alpha-glucosidase inhibitor activity and TSC 24 had the best antioxidative activity. Isolation of bioactive compounds from TSC 13 and TSC 24 is being conducted. This is the first report that endophytic fungi isolated from T. sumatrana exhibited anti alpha-glucosidase inhibitory and anti oxidative activities.

Abstract
BACKGROUND Edoxaban (the free base of DU-176b) is an oral, direct factor (F)Xa inhibitor in clinical development for the prevention and treatment of thromboembolic events. OBJECTIVES The aim of the present study was to evaluate the efficacy and safety of edoxaban for the prevention of venous thromboembolism (VTE) in patients undergoing total knee arthroplasty (TKA). PATIENTS/METHODS This was a randomized, double-blind, placebo-controlled, multicenter study conducted in Japan. A total of 523 Japanese patients were assigned to receive edoxaban 5, 15, 30 or 60 mg once daily or placebo for 11-14 days. A placebo control was used as neither low-molecular-weight heparin (LMWH) nor fondaparinux had been approved for thromboprophylaxis at the time of the study in Japan. The primary efficacy outcome was the incidence of VTE (lower-extremity deep vein thrombosis, symptomatic pulmonary embolism or symptomatic deep vein thrombosis). The primary safety outcome was the incidence of major and clinically relevant non-major bleeding. RESULTS Edoxaban produced a significant dose-related reduction in VTE: the incidence of VTE was 29.5%, 26.1%, 12.5% and 9.1% in the edoxaban 5-, 15-, 30- and 60-mg treatment groups vs. 48.3% in the placebo group. The incidence of major and clinically relevant non-major bleeding was similar across all groups without any significant differences among edoxaban doses or between edoxaban and placebo. CONCLUSIONS Edoxaban demonstrated significant dose-dependent reductions in VTE in patients undergoing TKA with a bleeding incidence similar to placebo.

Abstract
This research was conducted in the aim of preventing wild fire through reducing potential energy source to become in situ fertilizer. To prevent forest fires by reducing wood waste using lignocellulose-degrading fungi, six fungal isolates were tested for lignin and cellulose-degrading activity with Acacia mangium leaves and twigs over a period of 1 to 3 months. The fungi degraded 8.9-27.1% of the lignin and 14-31% of the holocellulose. The degradation rate varied depending on the fungal species. An increase in incubation time tended to decrease the amounts of holocellulose and lignin. However, the hot water soluble tended to increase following a longer incubation period. From the results obtained here, more time was needed to degrade lignin rather than other components in the sample.

Abstract
Gardenia jasminoides E. (Rubiaceae) methanol extracts showed the highest level of antifungal activity against Pleurotus ostreatus, a wood-rotting fungus, compared to five other methanol plants extracts; [Thuja orientalis L. (Cupressaceae), Datura innoxia (Solanaceae), Ligustrum japonicum T. (Oleaceae), Juniperus chinensis var. procumbens (Cupressaceae) and Mallotus japonica M. (Euphorbiaceae)] and selected for further analysis. Two antifungal compounds were isolated from n-butanol and ethyl acetate solubles in the methanol extracts of Gardenia jasminoides leaves and stems by bioassay-guided fractionation, using Pleurotus ostreatus. The antifungal compounds found for the first time in Gardenia jasminoides against Pleurotus ostreatus were identified as genipin and geniposide based on instrumental analyses. Both also had potent inhibitory effects on two plant pathogenic fungi; Fusarium oxysporum and Corynespora cassiicola.

Abstract
D-Serine, an endogenous modulator of NMDA receptors has been shown to play a vital role in many neuropsychiatric functions such as learning, memory, nociception and implicated in pathological conditions like schizophrenia and Alzheimer's disease. We propose possible therapeutic approaches for some CNS diseases and chronic pain, targeting the D-serine levels by manipulating its uptake, biosynthesis and metabolism.

Abstract
In an effort to prevent forest fires after the clear cutting of plantation forests, fungi capable of degrading lignocelluloses were isolated to make a fertilizer from the logging waste. Seventy five fungal species were isolated from fruiting bodies and mycelia in plantation forests of South and North Sumatera, Indonesia. Sixty three of the fungi were identified based on the appearance and morphological characteristics of their fruiting bodies and mycelia, as Pycnoporus sanguineus, Dacryopinax spathularia, Schizophyllum commune, Polyporus sp. and Trametes sp. Twenty fungi were categorized as white-rot fungi and 12 as brown-rot fungi. Moreover, isolates 371, 368, 265, 346, 345 and 338 were selected using indicators and tested for the ability to degrade lignin and holo-cellulose in mangium wood meal over 1 to 4 weeks. Results showed that the 6 fungi could degrade lignin and holo-cellulose in wood meal. An increase in incubation time tended to decrease the amounts of lignin and holo-cellulose. Isolate 371 was found to be best at degrading lignin and holo-cellulose in mangium wood meal.

Abstract
The in vitro metabolism of the calmodulin antagonist DY-9760e was investigated using liver microsomes from humans and three other animal species and compared with the in vivo metabolism in rats after intravenous administration of DY-9760e. Seven major metabolites were produced by human liver microsomes by the following metabolic pathways: N-dealkylation, phenyl hydroxylation, O-demethylation and imidazole oxidation. These metabolites were also produced by liver microsomes from monkeys, dogs and rats; additionally, a hydroxylated derivative of the indazole moiety was produced only by rat microsomes. To identify the structures of two imidazole ring metabolites whose authentic compounds could not be obtained, Escherichia coli co-expressing human cytochrome P450 CYP3A4 and NADPH-P450 reductase was used to biosynthesize these metabolites. NMR spectra elucidated the precise structures; oxidation occurred at the imidazole ring, and the subsequent ring-opening resulted in the generation of amide and formylamine groups. Glucuronide conjugates of the hydroxylated and O-demethylated derivatives were major components in rat bile. Therefore, DY-9760e metabolites generated in vitro correspond to the aglycones of the major metabolites observed in rat bile.
