Abstract
PURPOSE The present study investigated potential access vessels in patients receiving hemodialysis who underwent surgical aortic valve replacement and determined which approaches were most suitable for performing transcatheter aortic valve implantation. METHODS Consecutive patients undergoing hemodialysis with aortic valve stenosis who underwent surgical aortic valve replacement were included. Preoperative computed tomography data were analyzed to assess the vessel diameter and calcification. Simulations were conducted to determine the feasibility of inserting the 14-F eSheath of Sapien 3 via transfemoral, trans-cervical, trans-subclavian, and direct aorta approaches. RESULTS A total of 72 patients were included in this study. The access route was characterized by severe calcification of the common iliac artery. The transfemoral approach was feasible in 77.8% of the cases, but the rate decreased to 33% when the calculations were based on the maximum sheath extension diameter. The trans-cervical, trans-subclavian, and direct aortic approaches were suitable for many patients. Lower extremity artery disease was identified as a risk factor for the unsuitability of the transfemoral approach. CONCLUSIONS Common iliac artery calcification in patients undergoing hemodialysis restricts the use of the transfemoral approach. Therefore, some patients require alternative approaches.

Abstract
The μ-nitrido-bridged iron phthalocyanine homodimer is a potent molecule-based CH4 oxidation catalyst that can effectively oxidize chemically stable CH4 under mild reaction conditions in an acidic aqueous solution including an oxidant such as H2O2. The reactive intermediate is a high-valent iron-oxo species generated upon reaction with H2O2. However, a detailed comparison of the CH4 oxidation activity of the μ-nitrido-bridged iron phthalocyanine dimer with those of μ-nitrido-bridged iron porphyrinoid dimers containing one or two porphyrin ring(s) has not been yet reported, although porphyrins are the most important class of porphyrinoids. Herein, we compare the catalytic CH4 and CH3CH3 oxidation activities of a monocationic μ-nitrido-bridged iron porphyrin homodimer and a monocationic μ-nitrido-bridged heterodimer of an iron porphyrin and an iron phthalocyanine with those of a monocationic μ-nitrido-bridged iron phthalocyanine homodimer in an acidic aqueous solution containing H2O2 as an oxidant. It was demonstrated that the CH4 oxidation activities of monocationic μ-nitrido-bridged iron porphyrinoid dimers containing porphyrin ring(s) were much lower than that of a monocationic μ-nitrido-bridged iron phthalocyanine homodimer. These findings suggested that the difference in the electronic structure of the porphyrinoid rings of monocationic μ-nitrido-bridged iron porphyrinoid dimers strongly affected their catalytic light alkane oxidation activities.

Abstract
Photoemission orbital tomography (POT) from photoelectron momentum maps (PMMs) is a powerful technique that visualizes the shape of the molecular orbitals (MOs) of molecular films. For further utilization of POT, a simple and low-cost method of POT is highly required. Here, we propose a new POT method based on the PhaseLift algorithm (PhaseLift POT). This method utilizes a lifting procedure to convert the PMM, which is a second-order polynomial of MO coefficients, into a first-order polynomial of the lifted MO coefficients and further relaxes the equality constraint for a given PMM. We also established a method to improve the accuracy of phase retrieval from the noisy PMM data by using sparsity for MO coefficients (sparse PhaseLift POT). These methods make it possible to reconstruct the three-dimensional MOs, including phases of the wave function, directly from a single experimental PMM. This method can also precisely determine the adsorption-induced molecular deformations with an accuracy of 0.05 [Å]. Furthermore, the robust sparse PhaseLift POT is robust against unavoidable noise in the experimental PMMs due to the relaxation of the matching condition for a given PMM. Therefore, this will be an innovative tool for POT, especially for analyzing the dynamics of the molecules during the chemical reaction and excitation processes.

Abstract
An 82-year-old woman suddenly developed chest pain and apoplexy. Computed tomography (CT) showed acute type A aortic dissection, the true lumen in the brachicephalic artery was severely compressed by the faulse lumen. Pulsation in the either leg was not detected during induction of anesthesia. We evaluated the cerebral blood flow and lower extremity blood flow using near infrared spectroscopy (NIRS) during the operation, tissue oxygenation index (TOI) was continuously monitored during the operation. Cardiopulmonary bypass( CPB) was established by puncturing the true lumen in the ascending aorta and bicaval venous drainage. TOI was returned to normal range by CPB. Although the central repair (ascending aorta replacement) was performed, leg ischemia persisted. We performed ascending aorta-bifemoral bypass. After the operation, leg ischemia disappeared and CT revealed patency of the bypass graft. Postoperative course was uneventful without deterioration of neurological function. She was discharged 49 days after the operation.

Abstract
PURPOSE/OBJECTIVE(S) Brain metastases are common in NSCLC with up to 25% of patients having brain metastases (BMs) at the time of diagnosis and 30% developing BMs during their disease course. KRAS is an oncogenic driver in approximately 25% of lung adenocarcinomas. Genomic alterations co-occurring with KRAS are associated with distinct biological landscapes which may influence prognosis. Herein, we sought to identify correlations between genomic profiles, intracranial progression free survival (iPFS), and overall survival (OS). MATERIALS/METHODS We retrospectively reviewed 156 patients with KRAS-mutant lung adenocarcinoma BM who underwent SRS for their BMs at MSKCC from 2010-2022. Each patient had at least one tumor sample profiled with MSK-IMPACT, a custom FDA-cleared next-generation sequencing. Mutations, copy number alterations, and fusions were filtered for driver alterations using OncoKB. Survival outcomes were calculated from date of MRI indicating metastatic brain disease. RESULTS Of the 156 patients, 80 patients presented with BMs at diagnosis whereas 76 developed BMs during their disease course, with a median 2 lines of therapy prior to BM diagnosis. The most common KRAS mutation was G12C (n = 64; 41%), G12V (n = 26, 17%), G12D (n = 17; 11%), and G12A (n = 11; 7%). The most frequently co-altered genes were TP53 (n = 71, 46%), STK11 (n = 51, 33%), CDKN2A (n = 27, 17%), KEAP1 (n = 17, 11%), and SMARCA4 (n = 10, 6%). The presence of a KEAP1 co-occurring alteration was associated with inferior iPFS (HR 1.95, 95% CI 1.05 - 3.59, p = 0.035) and the presence of SMARCA4 was also associated with inferior iPFS (HR 2.28, 95% CI 1.05 - 4.95, p = 0.038). The presence of an STK11 mutation was associated with worse OS (HR 1.57, 95% 1.01 - 2.43, p = 0.045). In a multi-variate clinico-genomic model, KEAP1 and STK11 co-occurring alterations remained significantly associated with iPFS. Patients with KEAP1-altered tumors had an increased incidence of intracranial regional progression. The 24-month cumulative incidence of regional progression amongst KEAP1-altered tumors was 57% (95% CI, 29%-77%) compared with 37% (95% CI, 29%-46%) among KEAP1-wildtype tumors (P = 0.041). Patients with CDKN2A-altered tumors had an increased incidence of leptomeningeal disease (LMD) as a form of intracranial progression. The 24-month cumulative incidence of LMD amongst CDKN2A-altered tumors was 11% (95% CI, 2.7%-27%) compared with 4.1% (95% CI, 1.5%-8.8%) among CDKN2A-wildtype tumors (P = 0.023). CONCLUSION In our cohort of molecularly profiled KRAS-mutant lung adenocarcinoma BM patients treated with SRS, we found that co-occurring KEAP1 and STK11 were significantly associated with worse iPFS. We also observed that CDKN2A co-altered tumors had an increased incidence of LMD. These findings have implications for future efforts to personalize brain metastasis management based on comprehensive genomic profiling.

Abstract
PURPOSE/OBJECTIVE(S) Previous data have shown that inpatient radiation oncology consult services result in high-value care, with decreased length of stay, adoption and delivery of shorter fractionation schedules, and lower hospital costs. As such, institutions are increasingly creating inpatient radiation oncology services, although little is known about the allocation of limited resources for patients who may have limited prognosis, complex simulation requirements, and may have difficulty tolerating treatment. Thus, we sought to examine the utilization of simulation appointments for inpatient emergencies. MATERIALS/METHODS At our institution, inpatient consults are placed to a specialized inpatient palliative radiation oncology service, consisting of radiation oncologists specialized in metastatic and palliative RT, dedicated advanced practitioners, and nurses who specifically assess patients for medical appropriateness prior to simulation, including changes in disposition, medical stability, and adequate premedication. Electronic health record data was used to explore utilization trends of a single-institution inpatient radiation oncology consult service in 2020. Data regarding the nature and timing of consults, subsequent simulations and treatments, and patient outcomes including 14-day mortality and 30-day mortality from radiation (RT) start were assessed. Descriptive statistics are presented. RESULTS From 1/1/2020-12/31/2020, 1557 consults were placed. These consults led to 220 (14.1%) inpatient simulations. Of these planned simulations, 210 (95.5%) simulations occurred (of which 10 [4.8%] were rescheduled and eventually completed) and 179 (85.2%) completed treatment. Of 169 with mortality data available, 16 (9.5%) died within 14 days of RT start, and 41 (24.5%) died within 30 days of RT start. Of those with scheduling data (N = 193), 122 were same-day simulations (63.2%), and 507 (93.8%) occurred within 7 days or fewer. CONCLUSION Of 1557 inpatient consultations in one year, with appropriate metastatic and palliative experience, only a minority of consultations required inpatient simulation (14.1%). With appropriate nursing assessment, over 95% were able to complete simulation, with nearly two-thirds completing simulation on the same day, and nearly all patients completing simulation within a week of consultation. Most of these patients completed treatment and survived 30 days from treatment start. Thus, with highly specialized radiation oncologist clinical judgment in conjunction with appropriate nursing assessment prior to simulation scheduling, patients booked for simulation represent high-value utilization of resources.

Abstract
An 85-year-old woman underwent aortic arch replacement and thoracic endovascular aortic repair (TEVAR) 5 years ago. She suffered from chest and back pain. Computed tomography (CT) demonstrated enlargement of the aortic aneurysm by a type Ⅲb endoleak. TEVAR was performed to close a type Ⅲb endoleak with a relining technique uneventfully. Intraoperative completion aortography and postoperative CT confirmed the disappearance of a type Ⅲb endoleak. She was discharged 27 days after the treatment.

Abstract
PURPOSE/OBJECTIVE(S) To describe the feasibility of treating a complex and diverse group of patients using pencil beam scanning (PBS) proton stereotactic body radiation therapy (SBRT: 5 or fewer fractions, with a fraction size of at least 5 Gy). MATERIALS/METHODS Our center treats on average 105-120 PBS proton treatments daily, of which 9.5% of treatment courses are proton SBRT. Statistics of disease sites, treatment planning parameters (target volume, prescriptions, number of fields, SFO vs. MFO), and treatment efficiencies (scheduled time slots, actual treatment time) are presented for 305 consecutive SBRT patients receiving 1507 fractions in the past three years. Thermoplastic masks or Vacuum-lock bags are used to immobilize SBRT patients and index the patients' treatment position. Imaging guidance of orthogonal kV images and volumetric cone-beam CT is routinely used for patient setup. RESULTS SBRT patients are grouped based on the target locations: pelvis (31%), liver (17%), thoracic (13%), spine (8%), abdominal (8%), brain (7%), non-spine bone (7%), ocular (6%), and head and neck (2%). Only 112 patients (37%) were receiving their 1st RT course, whereas 113 (37%) had one prior in-field RT course, and 80 (26%) had multiple prior in-field RT courses. The median [IQR] target volume was 65.4 [29.3, 168] cc (range: 0.3-2475 cc). 72% of cases were planned with SFO and 28% with MFO. On average, 3.76 fields (range: 2 to 12) were planned for each treatment. 44% of the treatments were planned with three or fewer fields, and 10% received more than five fields, most of which involved repainting for moving targets. Over 97% of treatments were delivered in 5 fractions, with ∼3% delivered in 3 fractions. The median [IQR] prescription per treatment was 8 [7, 10] Gy (range: 5-18 Gy per treatment). 85% (84%) of the SBRT treatments were scheduled (delivered) in a 45-minute or shorter slot, and 6% (7%) of treatments were scheduled (delivered) in over a one-hour slot, most commonly for multiple isocenter treatments. 93% of treatments were delivered within 15 minutes of the planned treatment time or shorter. Deep-inspiration breath-hold (DIBH) was applied to 45% of liver SBRT cases, with the remaining 55% planned on 4D CT with (14%) or without (86%) abdominal compression. DIBH was applied in 13% of lung SBRT cases. The application of other motion mitigation approaches, such as volumetric repainting, was determined by the target motion amplitude and whether the patient could tolerate DIBH. CONCLUSION In the most diverse and largest proton SBRT experience delivered in the world over the past 3 years, over 300 patients were treated, demonstrating the feasibility and efficiency of delivering proton SBRT in a very busy center. The planning and treatment parameter statistics reported serve as a helpful reference for the proton community.

Abstract
PURPOSE/OBJECTIVE(S) Invisible ink tattoos allow for setup accuracy while avoiding the cosmetic permanence of visible ink tattoos. The goal of this trial was to evaluate patient-reported preference for the use of invisible ink tattoos in a radiation oncology clinic. MATERIALS/METHODS In an IRB-approved, prospective, feasibility trial, patients at a single institution receiving pencil beam scanning proton therapy to the thorax, abdomen, or pelvis underwent invisible ink tattoo-based treatment setup. Patient preference surveys comparing visible and invisible ink tattoos were completed prior to simulation (17 questions), immediately following simulation (5 questions), and at the end of treatment (18 questions), with preference scored on a 5-point Likert scale from strongly disagree to strongly agree, and cosmesis scored on a 4-point Likert scale of excellent-good-fair-poor. Differences in distributions were examined using Wilcoxon rank-sum tests, Fisher's exact tests, or chi-square tests, where statistical significance was considered at p<0.05. RESULTS Of 107 patients screened, 102 were enrolled and 94 completed all surveys. Mean age was 55.0 years, and 58.5% were female. Most patients were white (79.1%) and non-Hispanic (92.6%). Patients most commonly had breast (34.0%), prostate (16.0%), and lung (9.6%) cancer. An average of 5 (range 3-8) invisible ink tattoos were placed per patient. Overall, 75.5% of patients reported that they would prefer to receive invisible tattoos vs. visible tattoos, and 88.3% rated the overall cosmetic outcome of invisible ink tattoo marks as excellent or good. Compared to males, females were more willing to travel farther from their home in order to avoid receiving visible tattoos (45.4% vs. 23.1%, p = 0.035) and would pay additional money to avoid receiving visible tattoos (34.5% vs. 5.1%, p = 0.002). Patients who had previously received any tattoo (cosmetic or visible RT tattoos) were more satisfied with the appearance of their invisible ink tattoos compared to those who had never previously received tattoos (82.9% vs. 61.5%, p = 0.022). Patients receiving definitive intent RT were more satisfied with the appearance of the tattoos compared to those receiving palliative intent RT (67.1% vs. 38.9%, p = 0.011). Patients with at least a college education were less satisfied with the appearance of tattoos compared to those without a college education (67.0% vs. 95.0% p = 0.018). CONCLUSION These findings demonstrate stronger avoidance of visible tattoos and patient preference for invisible tattoos. The standard incorporation of invisible ink tattoos for patient setup should be strongly considered.

Abstract
Chelation therapy is a medical procedure for removing toxic metals from human organs and tissues and for the treatment of diseases by using metal-chelating agents. For example, iron chelation therapy is designed not only for the treatment of metal poisoning but also for some diseases that are induced by iron overload, cancer chemotherapy, and related diseases. However, the use of such metal chelators needs to be generally carried out very carefully, because of the side effects possibly due to the non-specific complexation with intracellular metal cations. Herein, we report on the preparation and characterization of some new poly(bpy) ligands (bpy: 2,2'-bipyridyl) that contain one-three bpy ligand moieties and their anticancer activity against Jurkat, MOLT-4, U937, HeLa S3, and A549 cell lines. The results of MTT assays revealed that the tris(bpy) and bis(bpy) ligands exhibit potent activity for inducing the cell death in cancer cells. Mechanistic studies suggest that the main pathway responsible for the cell death by these poly(bpy) ligands is apoptotic cell death. It was also found that the anticancer activity of the poly(bpy) ligands could be controlled by the complexation (anticancer activity is turned OFF) and decomplexation (anticancer activity is turned ON) with biorelevant metal cations. In this paper, these results will be described.

Abstract
A 53-year-old man presented to the emergency department with chest and back pain. Contrast-enhanced computed tomography( CT) revealed a Stanford type A acute aortic dissection with a pseudo-lumen occlusion. On the same day, the patient underwent emergent aortic arch replacement with frozen elephant trunk. When introducing cardiopulmonary bypass, arterial cannula was inserted into the right femoral artery. The day after surgery, swelling of the right lower leg appeared with CK and intramuscular compartment pressure elevation. Thus, the patient was diagnosed with compartment syndrome and decompressive fasciotomy was performed. Although there was no preoperative blood flow disturbance in the lower extremities on preoperative CT, lower limbs ischemia happened. Necrotic muscles in his right leg required debridement, but amputation was not needed. The patient was discharged unaided utilising orthotics on the day 120. In muscular, young male patients, care should be taken in the method of blood delivery.

Abstract
We report on a facile method for the optical resolution of cyclometalated iridium(III) (Ir(III)) complexes via diastereomers formed with chiral auxiliaries. The racemic carboxylic acids of Ir(III) complexes (fac-4 (fac-Ir(ppyCO2H)3 (ppy: 2-phenylpyridine)), fac-6 (fac-Ir(tpyCO2H)3 (tpy: 2-(4'-tolyl)pyridine)), and fac-13 (fac-Ir(mpiqCO2H)3 (mpiq: 1-(4'-methylphenyl)isoquinoline))) were converted into the diastereomers, Δ- and Λ-forms of fac-9 (from fac-6), fac-10 (from fac-4), fac-11 (from fac-6), and fac-14 (from fac-13), respectively, by the condensation with (1R,2R)-1,2-diaminocyclohexane or (1R,2R)-2-aminocyclohexanol. The resulting diastereomers were separated by HPLC (with a nonchiral column) or silica gel column chromatography, and their absolute stereochemistry was determined by X-ray single-crystal structure analysis and CD (circular dichroism) spectra. Spectra of all diastereomers of the Ir(III) complexes are reported. Hydrolysis of the ester moieties of Δ- and Λ-forms of fac-10, fac-11, and fac-14 gave both enantiomers of the corresponding carboxylic acid derivatives in the optically pure forms, Δ-fac and Λ-fac-4, -6, and -13, respectively.

Abstract
A 59-year-old woman was transferred to our hospital because of a sudden onset of chest and back pain. Computed tomography (CT) demonstrated Stanford type A acute aortic dissection with cardiac tamponade and right airway bleeding. Hemorrhage from ruptured false lumen extended along the pulmonary artery (PA), compression of the right PA were recognized due to hematoma surrounding the PA. An emergency operation was performed. The primary tear was located at the distal aortic arch, and total arch replacement with frozen elephant trunk was performed. During the operation, she had airway bleeding. The bleeding was thought to be due to the hematoma extending along the pulmonary artery. She was extubated 7th postopratively. She was discharged 44 days after the operation.

Abstract
Numerous biomimetic molecular catalysts inspired by methane monooxygenases (MMOs) that utilize iron or copper-oxo species as key intermediates have been developed. However, the catalytic methane oxidation activities of biomimetic molecule-based catalysts are still much lower than those of MMOs. Herein, we report that the close stacking of a μ-nitrido-bridged iron phthalocyanine dimer onto a graphite surface is effective in achieving high catalytic methane oxidation activity. The activity is almost 50 times higher than that of other potent molecule-based methane oxidation catalysts and comparable to those of certain MMOs, in an aqueous solution containing H2O2. It was demonstrated that the graphite-supported μ-nitrido-bridged iron phthalocyanine dimer oxidized methane, even at room temperature. Electrochemical investigation and density functional theory calculations suggested that the stacking of the catalyst onto graphite induced partial charge transfer from the reactive oxo species of the μ-nitrido-bridged iron phthalocyanine dimer and significantly lowered the singly occupied molecular orbital level, thereby facilitating electron transfer from methane to the catalyst in the proton-coupled electron-transfer process. The cofacially stacked structure is advantageous for stable adhesion of the catalyst molecule on the graphite surface in the oxidative reaction condition and for preventing decreases in the oxo-basicity and generation rate of the terminal iron-oxo species. We also demonstrated that the graphite-supported catalyst exhibited appreciably enhanced activity under photoirradiation owing to the photothermal effect.

Abstract
California poppy or golden poppy (Eschscholzia californica) is the iconic state flower of California, with native ranges from Northern California to Southwestern Mexico. It grows well as an ornamental plant in Mediterranean climates, but it might be invasive in many parts of the world. California poppy was also highly prized by Native Americans for its medicinal value, mainly due to its various specialized metabolites, especially benzylisoquinoline alkaloids (BIAs). As a member of the Ranunculales, the sister lineage of core eudicots it occupies an interesting phylogenetic position. California poppy has a short-lived life cycle but can be maintained as a perennial. It has a comparatively simple floral and vegetative morphology. Several genetic resources, including options for genetic manipulation and a draft genome sequence have been established already with many more to come. Efficient cell and tissue culture protocols are established to study secondary metabolite biosynthesis and its regulation. Here, we review the use of California poppy as a model organism for plant genetics, with particular emphasis on the evolution of development and BIA biosynthesis. In the future, California poppy may serve as a model organism to combine two formerly separated lines of research: the regulation of morphogenesis and the regulation of secondary metabolism. This can provide insights into how these two integral aspects of plant biology interact with each other.

Abstract
A 73-year-old man underwent drug eluting stent (DES) implantation in the left anterior descending artery (LAD) 11 years ago and in the right coronary artery (RCA) 8 years ago. He suffered from chest tightness and was diagnosed with severe aortic valve stenosis. Perioperative coronary angiography revealed no significant stenosis and thrombotic occlusion of the DES. Five days before operation, antiplatelet therapy was discontinued. Aortic valve replacement was performed uneventfully. But he developed chest pain and transient loss of consciousness, electrocardiographic changes were observed on the 8th postoperative day. Emergency coronary angiography revealed thrombotic occlusion of the drug eluting stent in the RCA, despite the postoperative oral adoministration of warfarin and aspirin. Percutaneous catheter intervention (PCI) restored the stent patency. Dual antiplatelet therapy (DAPT) was initiated immediately after the PCI, and anticoagulation therapy with warfarin was continued. Clinical symptons of stent thrombosis disappeared immediately after the PCI. He was discharged 7 days after the PCI.

Abstract
A C4h symmetrically substituted phthalocyanine, 1,8,15,22-tertrakis(2,4-dimethylpent-3-oxy)phthalocyanine (H2 TdMPPc), was used to synthesize Tb3+ -phthalocyanine double-decker complexes ([Tb(TdMPPc)2 ]s). Because H2 TdMPPc has C4h symmetry, S,S, R,R, and meso isomers of [Tb(TdMPPc)2 ] were obtained depending on the difference in the direction of the coordination plane of two C4h -type phthalocyanines with respect to a central Tb3+ ion. We investigated the physical properties of these [Tb(TdMPPc)2 ] isomers, including their single-ion magnetic properties, and found that the spin-reversal energy barrier (Ueff ) of the meso isomer was apparently higher than that of the enantiomers. Detailed crystal structural analyses indicated that the meso isomer has a more symmetrical structure than do the enantiomers, thereby suggesting that the higher Ueff of the meso isomer originated from the more highly symmetrical structure.

Abstract
Advancements in synthetic biology have facilitated the microbial production of valuable plant metabolites. However, constructing complete biosynthetic pathways within a single host organism remains challenging. To solve this problem, modular co-culture systems involving host organisms with partial pathways have been developed. We focused on Escherichia coli, a general host for metabolite production, and Pichia pastoris (Komagataella phaffii), a novel synthetic biology host due to its high expression of biosynthetic enzymes. Previously, we reported the co-culture of E. coli cells, which produce reticuline (an important intermediate for various alkaloids) from glycerol, with P. pastoris cells, which produce the valuable alkaloid stylopine from reticuline. However, Pichia cells inhibited E. coli growth and reticuline production. Therefore, we aimed to improve this co-culture system. We investigated the pre-culture time before co-culture to enhance E. coli growth and reticuline production. Additionally, we examined the optimal concentration of Pichia cells inoculated for co-culture and methanol addition during co-culture for the continuous expression of biosynthetic enzymes in Pichia cells. We successfully established an improved co-culture system that exhibited an 80-fold increase in productivity compared to previous methods. This enhanced system holds great potential for the rapid and large-scale production of various valuable plant metabolites.

Abstract
BACKGROUND In older people, frailty has been recognized as an important prognostic factor. However, only a few studies have focused on multidimensional frailty as a predictor of mortality and readmission among inpatients with pneumonia. OBJECTIVE The present study aimed to assess the association between preadmission frailty and clinical outcomes after the hospitalization of older patients with pneumonia. DESIGN Single-center, retrospective case-control study. SETTING Acute phase hospital at Kobe, Japan. PARTICIPANTS The present study included 654 consecutive older inpatients with pneumonia. MEASUREMENTS Frailty status before admission was assessed using total Kihon Checklist (KCL) score, which has been used as a self-administered questionnaire to assess comprehensive frailty, including physical, social, and cognitive status. The primary outcome was a composited 6-month mortality and readmission after discharge. RESULTS In total, 330 patients were analyzed (median age: 79 years, male: 70.4%, median total KCL score: 10 points), of which 68 were readmitted and 10 died within 6 months. After multivariate analysis, total KCL score was associated with a composited 6-month mortality and readmission (adjusted hazard ratio, 1.07; 95% confidence interval, 1.02-1.12; p = 0.006). The cutoff value for total KCL score determined by receiver operating characteristic curve analysis was 15 points (area under the curve = 0.610). The group with a total KCL score ≥ 15 points had significantly higher readmission or mortality rates than the groups with a total KCL score < 15 points (p < 0.001). CONCLUSIONS Preadmission frailty status in older patients with pneumonia was an independent risk factor for readmission and survival after hospitalization.

Abstract
OBJECTIVES Although better diet quality is inversely associated with mortality risk, the association between diet quality and mortality remains unclear in frail and non-frail older adults. Thus, we aimed to examine this association in older Japanese adults. DESIGN A prospective cohort study. SETTING AND PARTICIPANTS We used the data of 8,051 Japanese older adults aged ≥65 years in the Kyoto-Kameoka study. MESUREMENTS Dietary intake was estimated using a validated food frequency questionnaire. Diet quality was evaluated by calculating the adherence scores to the Japanese Food Guide Spinning Top (range, 0 [worst] to 80 [best]), which were stratified into quartiles. Frailty status was assessed using the validated self-administered Kihon Checklist (KCL) and the Fried phenotype (FP) model. Survival data were collected between February 15, 2012 and November 30, 2016. Statistical analysis was performed using the multivariate Cox proportional hazard analysis and the spline model. RESULTS During the median 4.75-year follow-up (36,552 person-years), we recorded 661 deaths. After adjusting for confounders, compared with the bottom adherence score quartile, the top quartile was associated with lower hazard ratio (HR) of mortality in frailty (HR, 0.73; 95% confidence interval [CI], 0.54-1.00) and non-frailty, as defined by the KCL (HR, 0.72; 95% CI, 0.52-1.01). In the spline model, regardless of frailty status defined by the KCL and FP model, adherence score showed a strongly dose-dependent inverse association with mortality up to approximately 55 points; however, no significant differences were observed thereafter. This association was similar to the results obtained in individuals with physical, cognitive, and depression as domains of KCL in the spline model. CONCLUSIONS Our findings demonstrate an L-shaped association between diet quality and mortality in both frail and non-frail individuals. This study may provide important knowledge for improving poor diet quality in older individuals with frailty or domains of frailty.

Abstract
A 78-years-old woman was referred to our institution for the treatment of right subclavian artery (SCA) aneurysm. She previously underwent total arch replacement via median sternotomy approach. Preoperative computed tomography revealed a 55 mm sized SCA aneurysm. Stent graft was inserted from brachiocephalic artery to right common carotid artery via the graft anastomosed. The orifice of the right SCA was covered with stent graft inserted into the right common carotid artery-brachiocephalic artery and the right SCA was occluded with coils distal to the aneurysm, carotid-SCA bypass was performed with 8 mm ePTFE graft. Postoperative examination confirmed complete exclusion of the aneurysm and patency of the bypass graft. We thought that hybrid treatment for this patient was a less invasive alternative to conventional surgical procedure.

Abstract
A 76-year-old man with thoracic aortic aneurysm was admitted to our hospital. Aortic arch replacement was performed uneventfully. He suffered from abdominal pain 17 days after the operation. Computed tomography (CT) scan revealed a strangulated bowel obstruction, and we performed emergent open abdominal surgery. During the operation, we found an adhesion between the greater omentum and the retroperitoneum. The small intestine was intussuscepted into this site, and strangulated with necrosis of a 35-cm length. We performed a partial resection of the small intestine. We encountered rare strangulated bowel obstruction after open heart surgery due to adhesion of the great omentum in a patient without a history of abdominal surgery.

Abstract
A 84-year-old man was diagnosed with complete atrioventricular block and underwent pacemaker implantation( PMI). Two days after the PMI, chest X-ray revealed left pneumothorax, and a chest tube was inserted. The pneumothorax did not improve, and computed tomography revealed left lung injury by the right ventricular lead. Surgical procedure through median sternotomy was performed, and the penetrated lead was removed. The injured right ventricle and left lung were repaired. Ten days after the surgical procedure, intravenous implantation of new right ventricular lead was performed. He was discharged 38 days after the surgical procedure.

Abstract
A 73-year-old woman suffered from premature ventricular contraction( PVC) which could not be controlled by medications. Holter 24-hour continuous recording electrocardiogram (Holter ECG) revealed 22,706 PVC beats/day. Upon further examination, she was found to have severe aortic stenosis and mild insufficiency. Preoperative electro-physiological study and standard 12-lead electrocardiogram revealed that the PVC originated from myocardium under the left coronary cusp. Aortic valve replacement and intraoperative cryoablation were performed. Her postoperative course was uneventful, Holter ECG revealed 638 PVC beats/day. Clinical symptons of PVC disappeared immediately after surgery. She was discharged 19 days after the operation.

Abstract
This study aimed to evaluate the association between locomotive syndrome (LS) and daily physical activity (PA) in community-dwelling older adults. This cross-sectional study included 80 healthy Japanese older adults (40 men and 40 women; age: 60-79 years). Habitual daily PA was evaluated using a triaxial wrist accelerometer. Participants were divided into two groups based on the results of the two-step test, stand-up test, and 25-question geriatric locomotive function scale. Binomial logistic regression analysis was conducted to examine the statistical relationships between daily PA and category of LS, adjusting for age from adjusted odds ratio (adjusted OR) with the 95 percent confidence intervals (95%CI) and bootstrap 95%CI. The mean step count and time spent on moderate to vigorous physical activity (MVPA) were significantly higher among non-LS participants than among LS participants in women, but not in men. Logistic regression analyses indicated that spending longer than 28 min/day on MVPA was significantly associated with a lower likelihood of LS relative to short time category under 28 min/day in women (adjusted OR = 0.12, 95%CI = 0.02-0.59, bootstrap 95%CI = 0.01-0.43), but not in men. This study suggests that in community-dwelling older women, those with higher MVPA had lower odds of LS, and daily MVPA was associated with LS, but not in men. Therefore, the associations between LS and daily physical activity were partly dependent on sex differences.

Abstract
Transporters have been used in the production of plant metabolites in microorganisms. This study introduced a tobacco multidrug and toxic compound extrusion transporter, NtJAT1, into alkaloid-producing Escherichia coli cells. NtJAT1 expression enhanced alkaloid production secretion into the medium by 14 folds. Our findings further demonstrate the usefulness of the transport-engineering approach.

Abstract
BackgroundRecently, the disease activity of rheumatoid arthritis (RA) was improved due to the ‘treat-to-target’ strategy. However, some patients remain various symptoms despite recommended treatment was performed. Then, the term of ‘difficult-to-treat RA (D2TRA)’ is widely recognized. Janus kinase inhibitor (JAKi) might be effective for D2TRA patients, because JAKi can simultaneously block the function of multiple cytokines.ObjectivesThe aim of this study was to evaluate drug retention rate and effectiveness of JAKi in patients with D2TRA.MethodsThis study included 220 RA patients (tofacitinib 101, baricitinib 83, upadacitinib 20, peficitinib 14, filgotinib 2) treated with JAKi. Sixty-two patients were treated as first line bDMARDs/JAKi (1st group), 57 patients were treated as second line bDMARDs/ JAKi (2nd group), 101 patients were treated as third and more bDMARDs/ JAKi. In these 101 patients, 25 patients did not met D2TRA criteria (non-D2TRA group) and 76 patients met D2TRA criteria (D2TRA group). Drug retention rate and effectiveness of JAKi were evaluated during 24 weeks in each group.ResultsUsage rate of methotrexate was lower and dosage of glucocorticoid was higher in D2TRA group than in other groups (Table 1). Drug retention rate at 24 weeks was 87.1% (54/62) in 1st group, 80.1% (46/57) in 2nd group, 88% (22/25) in non-D2TRA group, 61.8% (47/76) in D2TRA group. Drug retention rate was lower in D2TRA group compared to 1st group, 2nd group and non-DT2RA group (p<0.01, p=0.03, p=0.01). DAS28-CRP was 4.4, 4.0, 3.9, 4.4 at baseline, 3.0, 3.0, 3.3, 3.5 at 4 weeks, 2.5, 2.9, 2.7, 3.3 at 12 weeks, 2.5, 3.0, 2.9, 3.2 at 24 weeks in 1st group, 2nd group, non-D2TRA group and D2TRA group, respectively. Improvement ratio of DAS28-CRP was 32.9, 27.6, 20.4, 19.3 % at 4 weeks, 40.8, 26.5, 28.1, 19.5 % at 12 weeks, 40.8, 24.6, 18.7, 24.7 % at 24 weeks. DAS28-CRP was improved in all groups. Altough 1st group showed higher improvement ratio of DAS28-CRP at 24 weeks compared to 2nd group, non-DT2RA group and D2TRA group (p<0.01, p<0.01, p<0.01), there was no differences between DT2RA group and 2nd group or non-D2TRA group (p=0.95, p=0.48). SDAI was 22.9, 19.9, 18.3, 23.9 at baseline, 11.8, 11.9, 13.3, 14.4 at 4 weeks, 7.9, 11.3, 8.4, 13.3 at 12 weeks, 8.5, 11.5, 9.7, 12.6 at 24 weeks. CDAI was 21.3, 18.8, 17.6, 21.8 at baseline, 11.3, 11.2, 12.5, 13.9 at 4 weeks, 7.5, 10.9, 8.0, 12.3 at 12 weeks, 8.1, 10.7, 8.6, 12.1 at 24 weeks.
