Abstract
PURPOSE To evaluate improvement in local vascular perfusion of the lower limbs on intravoxel incoherent motion (IVIM) imaging after endovascular therapy (EVT). MATERIALS AND METHODS IVIM imaging was performed on 20 lower limbs of 16 patients with lower extremity arterial diseases before and after EVT. To estimate IVIM, diffusion-weighted lower-limb axial images (number of slices = 25 and slice thickness = 3.5 mm) were acquired using different b values (0, 300, and 1000 s/mm2). IVIM imaging with the simplified IVIM techniques was performed. The perfusion-related coefficient (D* [10-3 mm2/s]), perfusion fraction (f [%]), and D*f product (10-3 mm2/s %) were calculated before and 2-3 days after EVT. The ankle brachial index (ABI), mean D* (10-3 mm2/s), mean f (%), and mean D*f product (10-3 mm2/s %) before and after EVT were compared. RESULTS Successful revascularization was achieved in all cases. After EVT, the mean ABI significantly increased from 0.59 ± 0.19 to 0.87 ± 0.15 (p < 0.001, paired t test). The mean D* (10-3 mm2/s) (22.08 ± 3.26 versus 24.87 ± 2.65, p = 0.005, paired t test), and D*f product (10-3 mm2/s%) (551.03 ± 79.02 versus 634.55 ± 76.96, p = 0.002, paired t-test) of the lower limbs significantly increased after EVT, whereas f (%) (25.00 ± 1.28 versus 25.52 ± 1.61, p = 0.261, paired t-test) did not significantly increased after EVT. CONCLUSION D* (10-3 mm2/s) and D*f product (10-3 mm2/s %) on IVIM imaging could evaluate improvement in local vascular perfusion of the lower limbs after EVT. LEVEL OF EVIDENCE Level 4, Case Series.

Abstract
BACKGROUND Meticillin-resistant Staphylococcus aureus (MRSA) is the most common pathogen in orthopaedic surgical site infections (SSIs). However, few studies have investigated the transmission process of orthopaedic MRSA SSI. AIM To investigate the transmission process of orthopaedic MRSA SSI using epidemiological and molecular analyses and to determine a method to prevent MRSA SSI in nosocomial orthopaedic surgery. METHODS Active MRSA surveillance, preoperative decolonization and contact precautions for MRSA-positive cases was performed at our institution. Changes in epidemic strains were evaluated and the possibility of transmission from patients in an orthopaedic ward of a Japanese tertiary-care hospital was assessed by genotyping stored MRSA strains. In addition, data on the prevalence of MRSA SSI, MRSA colonization, and use of an alcohol antiseptic agent (mL/patient-days) during 2005-2022 were retrospectively assessed. FINDINGS SCCmec type II strain in the SSI group decreased over time, associated with fewer outbreaks. Even during a period of high infection rates, no cases of transmission-induced SSI from nasal MRSA carriers were identified. The infection rate correlated negatively with the use of an alcohol antiseptic agent (r = -0.82; P < 0.0001). Two cases among five nasal carriers developed MRSA SSI caused by strains different from those related to nasal colonization. CONCLUSION The infection control measures for transmission from the hospital reservoirs including strict adherence to hand hygiene and decolonization of carriers is likely to be important for the prevention of orthopaedic MRSA SSI. However, the need for contact precautions for decolonized nasal carriers might be low.

Abstract
The Health Enhancement Lifestyle Profile (HELP) was an assessment instrument for health-related behaviors and was translated into Japanese (HELP-J) using subjective rating scales. This study investigated the internal validity of the HELP-J using a Rasch analysis. Snowball and purposive sampling were used for data collection. The data obtained from the 109 respondents were subjected to Rasch analysis to assess their internal validity. The rating scale analysis supported a 3-category scale; five of the seven subscales showed unidimensionality. Thus, this study presents essential information on the possibility of translating the original HELP into Japanese and converting it into a unidimensional scale.

Abstract
Objective: Magnesium oxide is widely used for treating opioid-induced constipation, a serious analgesic-associated problem. Opioid analgesic users are often prescribed non-steroidal anti-inflammatory drugs, which are sometimes combined with acid suppressants to prevent gastrointestinal adverse events. Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect. This study was aimed at evaluating the effect of magnesium preparations combined with acid suppressants on the incidence of opioid-induced constipation by using the Food and Drug Administration Adverse Event Reporting System. Methods: Adverse events were defined per the Medical Dictionary for Regulatory Activities; the term 'constipation (preferred term code: 10010774)' was used for analysis. After adjusting for patient background factors using propensity score matching, acid suppressants' effect on constipation incidence was evaluated in opioid users prescribed magnesium preparations alone as laxatives by using a test for independence. Key Findings: The Food and Drug Administration Adverse Event Reporting System contains 14,475,614 reports for January 2004 to December 2021. Significantly increased constipation incidence was related to magnesium preparations combined with acid suppressants, especially proton pump inhibitors (P < 0.0001, McNemar's test). Conclusion: Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect; healthcare professionals should pay attention to this issue.

Abstract
A high-flow steerable microcatheter has been reported to be useful as a triaxial system. Moreover, the benefits of steerable microcatheters in acute-angle bifurcation vessel insertions and a compact coil-packing technique using intentional folding with a bendable catheter tip have been reported. However, research on the usefulness of a high-flow steerable catheter and 0.025-inch guidewire combination (steerable-wire) technique is lacking. Herein, we report a case of balloon-occluded retrograde transvenous obliteration (BRTO) via the femoral venous approach to illustrate the usefulness of the steerable-wire technique. The steerable-wire technique facilitates the selection of the wire into the target vessel. The steerable-wire can be used instead of the 0.035-inch guidewire, which is versatile as other devices can follow the steerable wire.

Abstract
BACKGROUND Nivolumab therapy is a standard-of-care treatment for heavily pretreated patients with advanced gastric cancer (AGC). Previous studies have reported improvement in the objective response rate to chemotherapy after nivolumab therapy for other types of cancer. This study evaluated the efficacy and safety of chemotherapy after nivolumab therapy in AGC. PATIENTS AND METHODS We conducted a prospective, multicenter, observational study in pretreated patients with nivolumab-refractory or -intolerant AGC. Patients received irinotecan, oxaliplatin-containing regimens, or trifluridine/tipiracil. The primary endpoint was overall survival. RESULTS A total of 199 patients were included (median age: 69 years; male: 70%; female: 30%). Median overall survival and progression-free survival were 7.5 months [95% confidence interval (CI): 6.7-9.7 months] and 2.9 months (95% CI: 2.2-3.5 months), respectively. Objective response and disease control rates were 16.8% (95% CI: 11.6% to 23.6%) and 18.9% (95% CI: 38.9% to 54.6%), respectively. A prognostic index using alkaline phosphatase and the Glasgow Prognostic Score was generated to classify patients into three risk groups (good, moderate, and poor). The hazard ratios of the moderate and poor groups to the good group were 1.88 (95% CI: 1.22-2.92) and 3.29 (95% CI: 1.92-5.63), respectively. At the initiation of chemotherapy, 42 patients had experienced immune-related adverse events due to prior nivolumab therapy. The most common grade 3-4 adverse events were neutropenia (7.5%), anemia (8.0%), and anorexia (7.5%). CONCLUSIONS The administration of cytotoxic chemotherapy after nivolumab therapy may give rise to a synergistic antitumor effect in AGC. Further investigation is warranted to confirm these findings.

Abstract
Fabry disease (FD) is a multi-organ disorder caused by a deficiency of alpha-galactosidase (α-GLA) or reduced activity of the enzyme due to mutations in the GLA gene on the X chromosome, making it an X-linked hereditary disease. A 37-year-old man previously diagnosed with sudden deafness and cardiac hypertrophy was referred to our department after an abnormal urine finding during a public health checkup. A renal biopsy revealed characteristic findings, and he was diagnosed with FD with a novel GLA abnormality (c.714dupT (p.I239Yfs*11)). We are currently administering enzyme replacement therapy (ERT) with agalsidase α. This case shows that a novel genetic abnormality in FD can be overlooked for 37 years, even in the presence of typical symptoms. The significance of a renal biopsy in diagnosing FD is emphasized, highlighting the crucial role of nephrologists. DOI: 10.52547/ijkd.7595.

Abstract
PURPOSE The incidence and risk factors of catheter-related bloodstream infections (CRBSI) in patients with intestinal failure (IF) have not been established, partly because catheter management methods vary from different facilities. This study aimed to identify the risk factors and incidence rate of CRBSIs in patients with IF who were given prophylactic treatment. METHODS Sixteen patients with IF who required home parenteral nutrition were enrolled in this study. Prophylactic management of CRBSI included monthly ethanol lock therapy and standardized infection prevention education. The outcomes included the incidence and risk factors of CRBSI. RESULTS The median incidence rate of CRBSI was 1.2 per 1000 catheter days. Univariate analysis showed that the risk of developing CRBSI was significantly associated with short bowel syndrome (< 30 cm) (p = 0.016). Other relevant findings included a significant negative correlation between serum albumin and CRBSI rate (r = - 0.505, p = 0.046), and past history of mixed bacterial infections was significantly associated with increased CRBSI rate (p = 0.013). CONCLUSION CRBSIs can still develop despite undergoing prophylactic management. Risk factors for CRBSI include the residual intestinal length, nutritional status, and susceptibility to certain microorganisms.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this analysis was to report subset analysis as to progression-free survival (PFS) and overall survival (OS) of particle-beam radiation therapy for operable early-stage lung cancer. MATERIALS/METHODS Patients of early-stage lung cancer (T1-T2aN0) who were eligible for radical surgery but did not wish to undergo surgery were treated by proton-ion (PT) or carbon-ion (CT) radiation therapy and enrolled in Japanese prospective registry. In this analysis, PFS and OS by clinical stage, tumor location, pathological confirmation and particle-ion type were evaluated. RESULTS A total of 274 patients were enrolled and included in efficacy and safety analyses. Most tumors were adenocarcinoma (44%), and 105 (38%) were not histologically confirmed and diagnosed clinically. 250 (91%) of 274 patients had tumors that were peripherally situated. 138 (50%) and 136 (50%) patients were treated by PT and CT, respectively. The median follow-up time for all censored patients was 42.8 months (IQR 36.7 - 49.0). No grade 3 or severe treatment-related toxicity was observed. 3-year PFS was 81% (95% CI;76-86) and OS was 93% (95% CI;89-96), respectively. As to particle-ion type, 3-year PFS were 79.0% and 81.9% in PT and CT (p = 0.19), and 3-year OS were 93.9% and 91.1% in PT and CT (P = 0.72), respectively. For PFS, pathological confirmation, clinical stage was significant factors but there were no significant differences by tumor location or particle-ion type; for OS, clinical stage was significant factor but there was no significant difference on pathological confirmation, tumor location or particle-ion type (Table1). Table 1. 3-year PFS and OS CONCLUSION: Particle therapy for operable early-stage lung cancer resulted in excellent 3-year OS and PFS on each subset.

Abstract
BACKGROUND Chemotherapy in combination with anti-epidermal growth factor receptor (EGFR) antibody is considered a first-line treatment regimen for RAS wild-type and left-sided metastatic colorectal cancer (mCRC), whereas second-line treatment regimens have not yet been established. Few studies have prospectively evaluated second-line treatment with anti-vascular endothelial growth factor antibody after first-line anti-EGFR antibody therapy for RAS wild-type mCRC. PATIENTS AND METHODS This non-randomized phase II trial investigated the clinical outcomes of second-line ramucirumab (RAM) plus fluorouracil, levofolinate, and irinotecan (FOLFIRI) after first-line anti-EGFR antibody in combination with doublet or triplet regimen in patients with RAS wild-type mCRC. The primary endpoint was the 6-month progression-free survival (PFS) rate. The secondary endpoints were PFS, overall survival (OS), objective response rate (ORR), rate of early tumor shrinkage (ETS), and safety. We hypothesized a threshold 6-month PFS rate of 30% and an expected 6-month PFS rate of 45%. Treatment was considered effective if the lower limit of the 90% confidence interval (CI) of the 6-month PFS rate was >0.30. RESULTS Ninety-two patients were enrolled in the study. The primary tumor was located on the left side in 86 (95.6%) patients. Twenty (22.0%) patients had received triplet plus cetuximab as previous therapy. Six-month PFS rate was 58.2% (90% CI 49.3% to 66.2%) with a median PFS of 7.0 months (95% CI 5.7-7.6 months). Median OS was 23.6 months (95% CI 16.5-26.3 months). The ORR and ETS rate were 10.7% and 16.9%, respectively, in 83 patients with measurable lesions. The 6-month PFS rate was comparable between patients previously treated with doublet and triplet regimens; however, median PFS was longer for the doublet regimen (7.4 versus 6.4 months, P = 0.036). CONCLUSIONS Our study demonstrated prospectively that RAM plus FOLFIRI is an effective second-line treatment after anti-EGFR antibody-containing first-line therapy in RAS wild-type and left-sided mCRC. Furthermore, the results were similar for patients who were previously treated with triplet regimen.

Abstract
PURPOSE/OBJECTIVE(S) Charged particle therapy (CPT) has been applied as a safe and effective treatment option for hepatocellular carcinoma (HCC). Although most HCC patients have cirrhosis, favorable treatment outcome has been achieved with CPT preserving liver function. After proton beam therapy (PBT) for patients with HCC, the liver volume in the non-irradiated area is often enlarged. Here, we evaluated whether enlargement of the non-irradiated liver affects preserving hepatic function and prognosis in HCC patients treated with PBT. MATERIALS/METHODS Among consecutive patients with HCC treated with PBT between April 2011 and July 2017, we retrospectively identified patients who fulfilled the following criteria: (i) receiving PBT to the right hepatic lobe, (ii) the left lateral segment was not irradiated, (iii) no local treatment was performed for liver within 12 months after PBT, and (iv) the albumin-bilirubin (ALBI) score was evaluable at 12 months after PBT. The left lateral segment was defined as the non-irradiated region and measured by contrast-enhanced CT just before and 3 months after PBT. ALBI scores just before and 12 months after PBT were compared to evaluate changes of hepatic function. Overall survival rate was estimated using the Kaplan-Meier method, and differences in survival between subgroups were examined using the log-rank test. The ALBI scores were compared using the Wilcoxon signed-rank test. RESULTS We identified 40 patients (male/female = 32/8). The median age at the start date of PBT was 72 (range, 54-87) years. The prescribed dose was 66.0-76.0 Gy (relative biological effectiveness) delivered in 10-38 fractions. The median follow-up was 61 (range, 12-126) months. The 5-year overall survival rates were 79.0% (95% CI: 60.4-100.0%) in the larger enlargement group (n = 16, enlarged volume of non-irradiated region 3 months after PBT ≥75 cm3) and 53.7% (95% CI: 36.0-79.9%) in the smaller enlargement group (n = 24, as above, <75 cm3), respectively (p = 0.21). The median ALBI scores just before and 12 months after PBT were -3.14 (95% CI: -3.22- (-2.53)) and -2.74 (95% CI: -3.07- (-2.42)) in the larger enlargement group (p = 0.09), and -2.91 (95% CI: -3.15- (-2.40)) and -2.59 (95% CI: -2.74- (-2.12)) in the smaller enlargement group (p = 0.006), respectively. CONCLUSION Our study suggests that larger enlargement of the non-irradiated liver after PBT is related to well-preserved liver function at 1 year and modestly associated with a favorable prognosis.

Abstract
PURPOSE/OBJECTIVE(S) We had conducted a multi-institutional phase II study to evaluate the safety and efficacy of dynamic tumor tracking-stereotactic body radiotherapy (DTT-SBRT) for lung tumors. The primary endpoint was 2-year local control, which was reported to be 95.2%. After the initial evaluation of the primary endpoint, the study was extended as an observational study which was designed to evaluate 5-year survival and late toxicities. We present the long-term results of DTT-SBRT for lung tumors. MATERIALS/METHODS The main eligibility criteria for the study were as follows: (1) primary or metastatic lung cancer with a diameter of 5 cm or less, and up to 3 lesions without any extrapulmonary lesions; (2) ineligibility to standard surgery, or patient's refusal of surgery; (3) ECOG-PS of 0 to 2; and (4) expected range of respiratory motion of 10 mm or more. The study included 48 patients from four institutions with the median age of 80 years (range, 49-90 years). Forty-two patients had primary non-small-cell lung cancer, and 6 patients had metastatic lung tumors. Forty-eight tumors (median diameter, 23.5 mm; range, 5-47 mm) in 48 patients were targeted for DTT-SBRT using a gimbal-mounted linear accelerator. Prior to treatment planning, spherical gold markers were placed around the tumor to detect internal tumor motion using fluoroscopy. The prescribed dose was 50 Gy in four fractions. Treatment beams were delivered with DTT according to a 4D model that predicts internal tumor motion with abdominal wall motion. DTT-SBRT was successfully delivered to all but one patient who had poor correlation between abdominal wall and tumor motion. RESULTS Median follow-up period at data cutoff was 5.0 years (interquartile range, 3.1-6.3 years). Twenty-nine patients died; the causes of death were cancer-specific in 10 patients, comorbidity in 14 patients (pulmonary disease, renal failure, cerebral infarction, other malignancies, etc.), and unknown in 5 patients without cancer recurrence. Overall survival at 5 years was 51.5% (95% confidence interval [CI], 36.5-64.6%). Progression-free survival and local control at 5 years were 41.0% (95% CI, 27.0-54.5%) and 92.6% (95% CI, 78.7-97.6%), respectively. There were no grade 4-5 toxicities. One patient (2%) developed grade 3 radiation pneumonitis at 3 months. Grade 2 toxicities were observed in 9 patients (19%), including dyspnea, radiation pneumonitis, pleural effusion, rib fracture, and dermatitis. CONCLUSION Dynamic tumor tracking SBRT achieved the long-term efficacy with low incidence of severe toxicities in lung tumors with respiratory motion. In this elderly patient cohort, non-cancer deaths were observed more than cancer-specific deaths.

Abstract
INTRODUCTION Aging, an inevitable physiological process, leads to morphological and histological degenerative changes in the mandibular condylar cartilage (MCC); however, the molecular mechanism has not yet been elucidated, and little information is available on age-related factors. Therefore, this study was designed to identify age-related factors by investigating the age-related differentially expressed genes (DEGs) and localization of their translated protein expression in the mandibular condyle. METHODS Mandibular condyles were collected from 10- and 50-week-old mice. Total RNA was extracted from the samples and then analyzed using cap analysis of gene expression (CAGE) to identify age-related DEGs. Gene ontology (GO) enrichment analysis was performed to determine which biological processes were most affected by aging in terms of gene expression using Metascape. The mandibular condyle samples were processed for histology to investigate morphological changes caused by aging and for immunohistochemistry to localize the protein expression encoded by age-related genes identified with CAGE. Semi-quantitative immunohistochemistry was performed to assess age-related extracellular matrix (ECM) protein levels in the MCC. The histological sections were also used for Alcian blue histochemistry to detect glycosaminoglycans (GAGs). RESULTS GO enrichment analysis revealed that the genes related to "extracellular matrix organization," including Acan, Col1a1, Col1a2, Col2a1, Mmp3, Mmp9, and Mmp13, were most differentially expressed in the aged mandibular condyle. Among these seven genes, Mmp3 was upregulated, and the others were downregulated with aging. Histological examination showed the age-related morphological and histological changes in the MCC. Immunohistochemical investigation showed the localization of matrix metalloproteinases (MMPs)-3, -9, and -13 and their substrate proteins, aggrecan, type I collagen, and type II collagen, in the mandibular condyle at 10 and 50 weeks, indicating different localizations between the young and the aged. In the aged MCC, semi-quantitative immunohistochemistry showed a significant decrease in the aggrecan protein level, and Alcian blue histochemistry showed a decrease in GAGs. CONCLUSION MMP-3, MMP-9, and MMP-13 contribute to the remodeling of the ECM of the MCC and subchondral bone during aging by degrading ECM proteins at specific times and sites under the regulation of their production and secretion.

Abstract
We investigated the effects of heat-killed Lactobacillus helveticus MCC1848 on daily mood states in healthy young adults. Participants (n=58) were randomised to receive heat-killed L. helveticus MCC1848 powder or placebo powder for 4 weeks. During the study period, adverse events were recorded in the participant diary. Mood states were assessed before and 2 and 4 weeks after initiation of the intervention. The primary outcomes were the shortened version of the Profile of Mood States 2 (POMS 2) scores. Secondary outcomes included other mood state (State-Trait Anxiety Inventory (STAI); visual analogue scale (VAS)), quality of life (acute form of the SF-36v2), sleep (Athens Insomnia Scale (AIS)) and fatigue (Chalder Fatigue Scale (CFS)) scores. Four weeks of heat-killed L. helveticus MCC1848 intake, compared to placebo, significantly improved the shortened version of the POMS 2 'friendliness' and the VAS 'relaxed' scores, which are two indicators of positive mood states. On the other hand, heat-killed L. helveticus MCC1848 intake had no significant effects on negative mood state items (e.g. anger, nervousness, confusion) assessed by the shortened version of the POMS 2, STAI and VAS. AIS and CFS scores also showed no significant differences. No adverse effects were observed with 4 weeks of heat-killed L. helveticus MCC1848 intake. These results suggest that daily consumption of heat-killed L. helveticus MCC1848 is safe and has the potential to improve positive mood states. UMIN Clinical Trial Registry: UMIN000043697.

Abstract
An accelerating aging society and rise in serious illnesses has led to an increase in deaths and made the demand for palliative care even greater. An integrated review was conducted to identify the impact of interprofessional education (IPE) on palliative/end of life (EOL) care for unlicensed health care students with a multidisciplinary approach. The databases searched included MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information Center (ERIC), PsycINFO, and the Cochrane Library's CENTRAL. Fifteen studies were included. Participants' disciplines included medicine, nursing, pharmacy, physical therapy, occupational therapy, social work, chaplain, public health and psychology. Nine were pre-post design and others were post course evaluations. One research study was an interventional trial with a comparative group. The selected studies included a variety of teaching strategies such as simulation or role play, clinical experience, case study, and TOSCE training. The importance of an interprofessional approach to palliative/EOL care has been highlighted, and our review suggests that combined IPE and palliative/EOL interventions can potentially impact palliative/EOL patient outcomes. More studies are needed to clarify the effectiveness of interprofessional palliative/EOL educational interventions including facilitators, learning outcomes, variable methods or teaching strategy, and the level of students.

Type of funding sources: Foundation. Main funding source(s): The Japan Cardiovascular Research Foundation under a contract with Bayer Yakuhin
Background
The AFIRE (Atrial Fibrillation and Ischemic Events With Rivaroxaban in Patients With Stable Coronary Artery Disease) trial demonstrated that rivaroxaban monotherapy was noninferior to combination therapy with rivaroxaban plus a single antiplatelet therapy regarding efficacy and superior for safety endpoints in patients with atrial fibrillation and stable coronary artery disease including patients not requiring revascularization [prior percutaneous coronary intervention (PCI) or bypass grafting (CABG)].
Purpose
The aim of this post-hoc subgroup analysis was to investigate the efficacy and safety of rivaroxaban monotherapy compared to combination therapy in patients with and without prior revascularization.
Methods
Among 2,215 patients included in the modified intention-to-treat analysis in the AFIRE trial, 1445 patients (65.2%) had undergone previous PCI alone, and 252 (11.4%) had undergone previous CABG. The remaining 518 patients (23.4%) was categorized as a group without prior revascularization and then compared with a group with prior revascularization (PCI or CABG). The primary efficacy end point was a composite of stroke, systemic embolism, myocardial infarction, unstable angina requiring revascularization, or death from any cause. The primary safety end point was major bleeding, according to the criteria of the International Society on Thrombosis and Hemostasis.
Results
In 1697 patients with prior revascularization, efficacy and safety endpoints of rivaroxaban monotherapy were superior to combination therapy (efficacy: HR 0.62, 95%CI 0.45-0.85, p=0.003; safety: HR 0.62, 95%CI 0.39-0.98, p=0.040), whereas there were no significant differences in efficacy and safety endpoints among 518 patients without prior revascularization (efficacy: HR 1.19, 95%CI 0.67-2.11, p=0.553; safety: HR 0.47, 95%CI 0.18-1.26, p=0.125). There was a borderline interaction of efficacy endpoint (P for interaction=0.055) by randomized treatment assignment (Figure 1 and Figure 2). Compared with combination therapy, the safety benefit of rivaroxaban monotherapy on any bleeding was significant in patients without prior revascularization (HR 0.59, 95%CI 0.38-0.93, p=0.022).
Conclusions
In patients with prior PCI or CABG, rivaroxaban monotherapy resulted in more favorable safety and efficacy outcomes than combination therapy. There was a borderline interaction for primary efficacy outcome between prior revascularization and anti-thrombotic therapy.

Abstract
The assessment of stent lumen patency via non-contrast-enhanced 2-dimensional time-of-flight magnetic resonance angiography (2D TOF MRA) is complex due to stent-related artifacts. However, an imaging technique using the phase-contrast method, which can reduce susceptibility to artifact, is available. Herein, we report the use of 3-dimensional velocity vector image obtained via 4-dimensional flow magnetic resonance imaging (4D flow MRI) for in-stent flow visualization after stent development in the right superficial femoral artery. Hence, instead of 2D TOF MRA, 4D flow MRI using the phase-contrast method can be performed to assess stent lumen patency as it reduces stent-related artifacts.

Abstract
Matrix-assisted laser desorption/ionization imaging mass spectrometry (IMS) is used to comprehensively visualize the spatial distribution of numerous biomolecules. The present study was designed to investigate the distribution of phospholipids in developing rat teeth by IMS to identify the characteristic phospholipid molecules for tooth development, and to evaluate the suitability of tissue preparation methods. Rats at postnatal day 3 were euthanized, and the resected head specimens were either fixed or not fixed with 4% paraformaldehyde (PFA), and decalcified or not decalcified in 10% ethylenediaminetetraacetic acid (EDTA) before being frozen. Subsequently, sections were prepared and mounted on glass slides coated with indium tin oxide, and analyzed by IMS. The mass spectra showed the highest peaks around m/z 706, 732, and 734 in the region of interest. Characteristic localization of signals in the tooth buds was seen around m/z 706 and 732, and a database search indicated that the corresponding molecules were phosphatidylcholines. The signals were localized to the dental papillae and enamel epithelia in the tooth buds. The PFA-fixed specimens with or without EDTA decalcification showed preserved IMS signals, while the non-fixed specimens showed fewer signals. Thus, PFA fixation with EDTA decalcification appears to be suitable for IMS analysis of calcified tissues.

Abstract
Febrile seizures are frequently accompanied by stress-induced hyperglycemia. Herein, we report the case of a 1.5-yr-old girl with hyperglycemia during febrile seizures who was subsequently diagnosed with glucokinase (GCK) maturity-onset diabetes of the young (MODY), considering its distinction from stress hyperglycemia. Following the development of febrile seizures owing to adenovirus infection, the patient presented a casual blood glucose level was 185 mg/dL. She had a multigenerational family history of diabetes and a hemoglobin A1c (HbA1c) level of 6.4%. Owing to the persistent glucose intolerance until the age of 5 years, genetic testing was performed, which revealed a heterozygous mutation in GCK, and the patient was diagnosed with GCK-MODY. Precise diagnosis of GCK-MODY individuals is important to avoid administering unnecessary antidiabetic medications. Even during hyperglycemia under stress, multigenerational diabetes and mildly elevated HbA1c levels can suggest GCK-MODY.

Abstract
Intravoxel incoherent motion imaging has its improvement-evaluating ability in lower limb perfusion after endovascular therapy in individuals with lower extremity arterial disease. Here, we present a 70-year-old man with intermittent claudication of the left lower limb, whose microperfusion on intravoxel incoherent motion imaging improved after endovascular therapy. The patient underwent intravoxel incoherent motion imaging of the lower extremities pre- and postendovascular therapy. After endovascular therapy, the left ankle brachial index increased from 0.46 to 1.06. The mean perfusion-related coefficient (10−3 mm2/s) of the left lower limb increased from 19.70 ± 3.17 to 24.81 ± 3.41, and mean perfusion fraction (%) of the left lower limb slightly increased from 24.41 ± 0.96% to 25.20 ± 1.89% after endovascular therapy. Therefore, successful revascularization can improve microperfusion on intravoxel incoherent motion imaging in a patient with lower extremity arterial disease.

Abstract
ABSTRACT
Central venous catheterization is a commonly used procedure for disease management. However, the procedure is not without risks of severe morbidity. We herein report hemostasis for accidental venous puncture using thoracoscopy. A 44-year-old man with short bowel syndrome and chronic renal failure required central venous catheterization for nutritional management and hemodialysis. Right internal jugular vein puncture was performed under ultrasonographic guidance, and the guidewire was inserted into the right atrium under fluoroscopic guidance. However, the operator inadvertently perforated the vein, and the thoracic cavity was entered while inserting the introducer. The patient’s vital signs were stable; therefore, we performed emergency surgery after computed tomography and achieved hemostasis through thoracoscopic surgery. Sufficient caution should be exercised while inserting central venous catheters through a thrombosed internal jugular vein. In some instances of catheter-induced vessel injury, combined surface and thoracoscopic hemostasis may be a reliable and minimally invasive management option.

Abstract
Background The increasing ratio of functional future liver remnant (functional %FLR) after modified associating liver partition and portal vein ligation/embolization for staged hepatectomy (modified-ALPPS) compared with portal vein embolization (PVE) has not been comprehensively evaluated. Purpose To compare the increasing ratio of functional %FLR between modified-ALPPS and PVE via technetium-99 m-galactosyl human serum albumin single-photon emission computed tomography (99mTc-GSA SPECT/CT) fusion imaging. Material and Methods Seven and six patients underwent modified-ALPPS (modified-ALPPS group) and PVE (PVE group) from 2015 to 2019. The functional %FLR on 99 mTc-GSA SPECT/CT fusion imaging was assessed before and 1 week (modified-ALPPS group) and 3 weeks (PVE group) after each procedure. The increasing ratio of functional %FLR (functional %FLR ratio) was calculated and compared between the two groups. Moreover, the hypertrophy ratio of future liver remnant volume (FLRV ratio) and atrophy ratio of embolized liver volume (.ELV ratio) were evaluated. Results The mean functional %FLR ratios of the modified-ALPPS group (1.47 ± 0.15) and the PVE group (1.49 ± 0.20) were comparable (p > .05). The median FLRV ratio of modified-ALPPS group (1.48) was higher than that of the PVE group (1.16), the median ELV ratio of the PVE group (0.81) was lower than that of the modified-ALPPS group (0.94), and the results significantly differed between the two groups (p < .05). Conclusion The increasing ratio of functional %FLR was comparable between modified-ALPPS and PVE. Compared with PVE, ALPPS was associated with a higher hypertrophy rate of the remnant liver but a lower atrophy rate of the embolized liver.

Abstract
Abstract
Background
The AFIRE (Atrial Fibrillation and Ischemic Events With Rivaroxaban in Patients With Stable Coronary Artery Disease) trial showed both noninferiority for efficacy and superiority for safety endpoints of rivaroxaban monotherapy compared to rivaroxaban plus antiplatelet therapy (combination therapy) in patients with atrial fibrillation (AF) and stable coronary artery disease (CAD). However, no accumulating evidence regarding efficacy and safety of these fixed-dose direct oral anticoagulant therapy was available in underweight and obese patients.
Purpose
The aim of this post-hoc analysis of the AFIRE trial was to evaluate outcomes of rivaroxaban monotherapy (vs. combination therapy) in patients with AF and stable CAD across body mass index (BMI) categories.
Methods
Patients were categorized into groups 1 (underweight: BMI of <18.5 kg/m2), 2 (normal: BMI of 18.5 to <25 kg/m2), 3 (overweight: BMI of 25 to <30 kg/m2), and 4 (obesity: BMI of ≥30 kg/m2). Efficacy (a composite of all-cause death, myocardial infarction, unstable angina requiring revascularization, stroke, or systemic embolism) and safety (major bleeding defined according to International Society on Thrombosis and Haemostasis criteria) were compared between rivaroxaban monotherapy and combination therapy across BMI categories.
Results
We analyzed 2,054 patients with a median age of 75.0 (interquartile range [IQR], 69 to 80)) years old and CHA2DS2-VASc of 4 (IQR, 3 to 5). Group 1 through 4 included 72 (3.5%), 1,158 (56.4%), 680 (33.1%), 144 (7.0%) patients and 62.3%, 52.3%, 36.2%, and 30.3% were received reduced dose of rivaroxaban, respectively. Although the sample sizes for group 1 and 4 were limited, monotherapy was superior to combination therapy for efficacy in group 2 (hazard ratio [HR], 0.64; 95% CI, 0.44 to 0.95) and safety in group 3 (HR, 0.25; 95% CI, 0.10 to 0.62), whereas a significant difference in the endpoints was not observed in the other BMI categories. Impact of monotherapy on endpoints did not have a significant interaction in BMI.
Conclusions
Rivaroxaban monotherapy had similar effect on prognosis across all BMI categories in patients with AF and stable CAD.

Abstract
OBJECTIVE To determine whether the combination of scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDX) and immunostaining would visualize the mineral and protein distribution in the same histological sections. METHODS Paraffin sections of fixed rat hindlimbs were processed for SEM-EDX and subsequently for immunofluorescence staining. RESULTS The localization of calcium, phosphorus, and carbon with type II collagen could be visualized in the same region of calcified growth plate cartilage on the same section. CONCLUSIONS The combination of SEM-EDX and immunostaining is effective for visualizing mineral and protein distribution in the same histological sections.

Abstract
Bochdalek hernia is the most common type of congenital diaphragmatic hernia( CDH). Patients with CDH often develop cardiopulmonary dysfunction secondary to pulmonary hypoplasia and pulmonary hypertension, which necessitates emergency surgery. Advanced cardiopulmonary management is essential in such cases;therefore, patients should be treated at a well-facility that is familiar with the treatment of CDH. Respiratory management using gentle ventilation and control of pulmonary hypertension using nitric oxide are necessary for preoperative stabilization of patients. Intraoperatively, the hernia should be cautiously reduced and contents should be returned into the abdominal cavity. Surgery is performed to secure the circumference of the rim and ensure firm closure of the defect. Thoracoscopic surgery may be considered for late-onset cases with a stable general condition.

Abstract
Acute disseminated encephalomyelitis (ADEM) is a rare and immune-mediated inflammatory disorder of the central nervous system (CNS) that can be triggered by infections and vaccinations. To date, only anecdotal case studies have reported the association between ADEM incidence and seasonal influenza vaccines, and multiple studies have found no association. This study aimed to investigate the association between the incidence of ADEM and seasonal influenza vaccines in a real-world setting using data from the United States Vaccine Adverse Event Reporting System (VAERS). Further, propensity score matching and disproportionality analysis was performed by calculating the adjusted reporting odds ratio (ROR) of reported ADEM cases associated with seasonal influenza vaccines using multiple logistic regression. Additionally, we analysed the time-to-onset using Weibull shape parameters (WSPs). The VAERS database contained 390,352 adverse events reported from January 2011 to December 2020. The ROR of seasonal influenza vaccines for ADEM was 3.02 (95% confidence interval: 1.72-5.33). The median duration (interquartile range) of ADEM was 11.0 (5.0-33.0) days. The median duration of ADEM induced by egg culture-based influenza vaccine (Egg-based vaccine) and cell culture-based influenza vaccine (Cell-based vaccine) was 10.0 (5.0-24.0) and 91.0 (79.0-125.0) days (P < 0.001), respectively. Only Cell-based cases had WSP β > 1, indicating a wear-out failure type. The incidence of ADEM within 30 days after administration of egg- and Cell-based vaccines was 78.6% and 0.0%, respectively. Our findings indicate that ADEM incidence is associated with seasonal influenza vaccines; thus, careful monitoring of ADEM is required within the first month of Egg-based vaccination and after two months of Cell-based vaccination. Neurologists and general practitioners should exercise caution, as the timing for careful monitoring varies depending on the vaccine type.

Abstract
OBJECTIVE The purpose of this study was to evaluate the functional duration and survival rate of tympanostomy ventilation tubes and the complications associated with their use in pediatric patients who underwent tube insertion for otitis media with effusion (OME). Complications were analyzed including recurrence and tympanic membrane perforation after the tube removal or extrusion. METHODS Altogether, 447 ears from 234 pediatric patients younger than 15 years of age were studied retrospectively. All patients had undergone long-term tympanostomy ventilation tube: the Goode T-tube insertion for OME at the Osaka Women's and Children's Hospital, which is the pediatrics specialty hospital between April 2014 and March 2016. They were typically followed up every 3-4 months or more frequently if necessary due to otorrhea or tube infection. Subsequently, the tube duration, survival rates of the tube especially at 22 months after insertion defined as "full-term placement", and the rates of recurrence and perforation were calculated and statistically evaluated. RESULTS Of 447 ears, 335 ears from 184 patients underwent their first tube insertion, and 112 ears from 64 patients underwent their second or subsequent tube insertion within the targeted period. Two hundred ears from 106 patients were associated with a cleft palate. The survival rate at full-term placement was 51.7%. The recurrence rate was 56.3%, and the rate of the tympanic perforation was 8.5%. CONCLUSIONS Approximately half of the tubes survived for 22 months. The perforation rate was relatively low; however, recurrence of OME was seen in more than half the ears.

Abstract
Abstract
Background: DSP-7888—an investigational immunotherapeutic cancer vaccine derived from Wilms’ tumor 1 (WT1)—induced WT1-reactive T cells, the activity of which was maintained and enhanced by anti-PD-1 mAbs (preclinical; Goto, et al. ASH 2016). Results from the Ph 1b dose search cohort of a Ph 1b/2 study of DSP-7888 + immune checkpoint inhibitors (ICIs) NIV or PEM in ASTs (NCT03311334) are presented.
Methods: Pts (aged ≥18 y; ECOG PS 0-1; locally advanced/metastatic solid tumors; approved for NIV or PEM) received intradermal (ID) DSP-7888 10.5 mg once weekly (wk) (Q1W) + NIV 240 mg IV Q2W for 4 (Arm 1) or PEM 200 mg IV Q3W for 6 (Arm 2) wks (induction), then DSP-7888 + NIV (Q2W; Arm 1) or PEM (Q3W; Arm 2) (maintenance). A DSP-7888 3.5-mg dose cohort would open if dose limiting toxicities (DLTs) occured in >1 of 6 pts. Primary objectives: evaluate safety (including DLTs) and identify the recommended Ph 2 dose of DSP-7888 + NIV or PEM.
Results: At data cutoff (March 30, 2021), 13 pts (mean age 63.8 [range 38-82] y; 61.5% male; median 3 (1-5) lines of prior therapy; 84.6% prior ICIs) were enrolled and treated with DSP-7888 10.5 mg + NIV (Arm 1, n=7) or PEM (Arm 2, n=6). Treatment-emergent adverse events (TEAEs) were reported in 100% (any grade) and 76.9% (grade ≥3; most commonly injection site reactions [ISR; 30.8%]) of pts (Table). No DLTs occurred during the evaluation period (NIV, 4 wk; PEM, 6 wk), establishing 10.5 mg as the recommended dose for DSP-7888 + NIV or PEM. Serious AEs were reported in 7 (53.8%) pts (2 [15.4%] related to DSP-7888). At efficacy data cutoff (May 4, 2020), 2 (15.4%) pts with prior ICIs achieved partial response, which lasted 9.5 and 5.5+ months; 6 pts achieved stable disease (n=4 ≥8 months) and 3 had progressive disease.
Conclusions: DSP-7888 + NIV or PEM was generally tolerable at 10.5 mg ID (most common TEAE was ISR) and showed evidence of preliminary antitumor activity. An expansion cohort in ovarian cancer is enrolling.

Abstract
Background Few prospective studies have used liquid biopsy testing in RAS-mutant metastatic colorectal cancer (mCRC), and its clinical significance remains unknown. Therefore, this study aimed to carry out a biomarker analysis by liquid biopsy using updated data of the phase II trial of FOLFOXIRI plus bevacizumab as first-line chemotherapy for RAS-mutant mCRC. Materials and methods A total of 64 patients who received modified FOLFOXIRI regimen (irinotecan 150 mg/m2, oxaliplatin 85 mg/m2, levofolinate 200 mg/m2, and fluorouracil 2400 mg/m2) plus bevacizumab biweekly were enrolled. The primary endpoint was the objective response rate (ORR). Plasma samples were collected at pre-treatment, 8 weeks after treatment, and progression in participants included in the biomarker study. The levels of circulating tumour DNA (ctDNA) and specific KRAS and NRAS variants were evaluated using real-time PCR assays. Results There were 62 patients (median age: 62.5 years, 92% performance status 0, 27% right side) who were assessable for efficacy and 51 for biomarker analysis. ORR was 75.8% (95% confidence interval 65.1% to 86.5%). The median progression-free survival was 12.1 months, and the median overall survival (OS) was 30.2 months. In 78% of patients, RAS mutations disappeared in the ctDNA at 8 weeks after treatment; these patients tended to have better outcomes than those with RAS mutations. Interestingly, RAS mutations remained undetectable during progression in 62% of patients. Survival analysis indicated that the median OS from progression was significantly longer in patients with RAS mutation clearance than in those with RAS mutation in the ctDNA at disease progression (15.1 versus 7.3 months, hazard ratio: 0.21, P = 0.0046). Conclusions Our biomarker study demonstrated no RAS mutations in ctDNA at disease progression in 62% of patients with RAS-mutant mCRC. Both OS and post-progression survival were better in patients with clearance of RAS mutations in ctDNA after triplet-based chemotherapy. First-line FOLFOXIRI plus bevacizumab is effective for RAS-mutant mCRC with comparable efficacy in elderly patients. RAS mutations disappeared in ctDNA after intensive chemotherapy in 62% of patients with mCRC with RAS-mutant tumours. Survival time was longer in patients with RAS mutation clearance than in those with RAS mutations in ctDNA.

Abstract
Objective The present study was designed to investigate the whole transcriptome of periodontal tissues of both young and aged mice to identify the characteristic up‐regulation of protease genes with aging and to localize their translated protein products in the periodontal tissues. Background The metzincin protease superfamily is composed of matrix metalloproteinases (MMPs), a disintegrin and metalloproteinases, and a disintegrin and metalloproteinases with thrombospondin motifs. Up‐regulation of these extracellular matrix‐degrading proteases has been implicated in senescence of tissues and organs, including the skin. However, few studies have investigated the expression profiles of these proteases and potential involvement in aging of periodontal tissues. Methods Periodontal tissues with the surrounding mandibular bones were collected from 50‐ and 10‐week‐old mice. Total RNA was extracted from the periodontal tissue and analyzed by cap analysis of gene expression (CAGE) to identify differentially expressed genes encoding the metzincin proteases. Furthermore, quantitative real‐time polymerase chain reaction (qRT‐PCR) was performed to validate the CAGE results, and the phenotypic expression of proteases involved in aging was localized via immunohistochemical analysis. Results The CAGE results showed that the expression levels of MMP‐3, ‐10, and ‐12 were up‐regulated at 50 weeks. Subsequent qRT‐PCR analysis showed that the gene expression levels of MMP‐3 and ‐10 were significantly increased with age. MMP‐10 immunoreactivity was localized exclusively in the cementum and alveolar bone adjacent to the periodontal ligament and was stronger and broader in aged mice than young mice. MMP‐3 immunoreactivity was localized in the periodontal ligaments at both 10 and 50 weeks. Conclusion In the present study, we demonstrated that the expression of MMP‐3 and ‐10 increased with aging and identified their characteristic localizations in aged periodontal tissues.

Abstract
Vincristine (VCR) is an important drug used in R-CHOP regimens for the treatment of non-Hodgkin's lymphoma. The purpose of this study was to examine whether the administration method affects the incidence of VCR-induced peripheral neuropathy. We investigated the ratio of VCR-induced peripheral neuropathy during rapid intravenous infusion and intravenous drip infusion. A total of 71 patients who had received six or more courses of R-CHOP from January, 2015 to December, 2016 at Komaki City Hospital and Ogaki Municipal Hospital were retrospectively investigated. Peripheral neuropathy was observed in 27/39 patients (69 %) and 24/32 (75 %) in rapid intravenous infusion and intravenous drip infusion of VCR, respectively (P = 0.79). Peripheral neuropathy was observed at a high frequency in this study. Additionally, there was no difference in frequency of peripheral neuropathy due to the difference in administration method. In both groups, the degree of peripheral neuropathy was grade 1 and grade 2 in most patients. However, in rapid intravenous infusion, grade 3 peripheral neuropathy was observed. Some cases required dose reduction and discontinuation in rapid intravenous infusion. In contrast, there were no discontinuing patients in the intravenous drip infusion. Therefore, it was suggested that intravenous drip infusion of VCR reduced serious peripheral neuropathy because the ratio requiring dose reduction and discontinuation was less than that in the rapid group. In conclusion, this study is informative as there are few reports focusing on the administration method of vincristine.

Abstract
Elastofibroma dorsi is a well-known benign chest wall tumor. Herein, we present a case in which an elastofibroma protruded into the thoracic cavity, leading to inverted intercostal hernia. Imaging revealed a soft tissue mass containing fat, typical of elastofibroma dorsi; however, precise diagnosis was difficult owing to the location of this mass that protruded into the thoracic cavity. Liposarcoma had to be ruled out because it was a growing fat-containing mass. Considering that the tumor moved while the patient was undergoing computed tomography-guided biopsy in the prone position, a diagnosis of inverted intercostal hernia of elastofibroma dorsi was made. We report this case with a review of current literature.

Abstract
Abstract
Background
While sacrococcygeal teratoma (SCT) is a tumor originating from the tip of the sacrum, presacral tumors are accompanied by Currarino syndrome (CS) and classified as the Altman’s type IV sacrococcygeal tumors. They are quite different in their pathologies despite the similar location. To the best of our knowledge, there are no published reports comparing their prognosis; therefore, we analyzed their postoperative results and long-term prognosis. Twenty patients with SCT, including CS, who were being followed up at the outpatient clinic of the Department of Pediatric Surgery, Miyagi Children's Hospital between 2004 and 2020, were enrolled in the study. Patients were divided into two groups: those who developed SCT without anorectal malformation and sacral dysplasia, and those who developed presacral tumors with anorectal malformation or sacral dysplasia as CS. Patient records were retrospectively reviewed for clinical details, postoperative complications, and long-term prognosis.
Results
Tethered cord syndrome occurred significantly more frequently in the CS group (p = 0.0108). However, no significant differences were observed for malformations other than tethered cord syndrome. Early complications in the CS group were significantly higher than those in the SCT group (p = 0.023); the most common complication was dysuria. Regarding long-term prognosis, 70% of patients in the CS group complained of defecation disorders, which was significantly higher than that in the SCT group (p = 0.0198). Voiding dysfunction was also more common in the CS group.
Conclusions
There were significant differences between SCT and CS regarding the rate of development of tethered cord syndrome, short-term postoperative complications, and long-term prognosis. Thus, they are different diseases with the only commonality being the presence of a sacrococcygeal tumor. Furthermore, this study indicated that the background and prognosis of the two conditions were also quite different.

Background
Impella-related hemolysis is a well-known complication, which we sometimes experience in the clinical practice depending on various hemodynamic status including right ventricular impairment.
Methods
We enrolled consecutive patients with cardiogenic shock who received Impella support between March 2018 and December 2020. The association between pulmonary artery pulsatility index (PAPi) immediately after Impella insertion and the occurrence of hemolysis was investigated. Hemolytic event was defined as detection of hemoglobinuria and elevated lactate dehydrogenase level over 2.5 folds of upper normal range.
Results
Among 38 patients (median 71 y; men 61%; LVEF 29%) included in this study, hemolysis occurred in 18 patients (47%). Incidence of hemolysis was significantly higher in the low PAPi group (< 1.3) compared with the normal PAPi group (≥ 1.3) (67% vs. 33%, p = 0.0176; Figure 1). The low PAPi (<1.3) was significantly associated with the occurrence of hemolysis with a hazard ratio of 5.71 (95% confidence interval 1.09–29.91, p = 0.0313) adjusted for other clinically significant variables.
Conclusions
In patients with right ventricular impairment with lower PAPi, it might be encouraged to be aware of the risk of hemolysis, maintaining volume status and considering inotropes administration. Abstract Figure.
