Abstract
Clinical use of gene panel testing for hematopoietic neoplasms in areas, such as diagnosis, prognosis prediction, and exploration of treatment options, has increased in recent years. The keys to interpreting gene variants detected in gene panel testing are to distinguish between germline and somatic variants and accurately determine whether the detected variants are pathogenic. If a variant is suspected to be a pathogenic germline variant, it is essential to confirm its consistency with the disease phenotype and gather a thorough family history. Donor eligibility must also be considered, especially if the patient's variant is also detected in the expected donor for hematopoietic stem cell transplantation. However, determining the pathogenicity of gene variants is often complicated, given the current limited availability of databases covering germline variants of hematopoietic neoplasms. This means that hematologists will frequently need to interpret gene variants themselves. Here, we outline how to assess the pathogenicity of germline variants according to criteria from the American College of Medical Genetics and Genomics/Association for Molecular Pathology standards and guidelines for the interpretation of variants using DDX41, a gene recently shown to be closely associated with myeloid neoplasms with a germline predisposition, as an example.

Abstract
Due to the proliferation of genetic testing, pathogenic germline variants predisposing to hereditary hematological malignancy syndrome (HHMS) have been identified in an increasing number of genes. Consequently, the field of HHMS is gaining recognition among clinicians and scientists worldwide. Patients with germline genetic abnormalities often have poor outcomes and are candidates for allogeneic hematopoietic stem cell transplantation (HSCT). However, HSCT using blood from a related donor should be carefully considered because of the risk that the patient may inherit a pathogenic variant. At present, we now face the challenge of incorporating these advances into clinical practice for patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) and optimizing the management and surveillance of patients and asymptomatic carriers, with the limitation that evidence-based guidelines are often inadequate. The 2016 revision of the WHO classification added a new section on myeloid malignant neoplasms, including MDS and AML with germline predisposition. The main syndromes can be classified into three groups. Those without pre-existing disease or organ dysfunction; DDX41, TP53, CEBPA, those with pre-existing platelet disorders; ANKRD26, ETV6, RUNX1, and those with other organ dysfunctions; SAMD9/SAMD9L, GATA2, and inherited bone marrow failure syndromes. In this review, we will outline the role of the genes involved in HHMS in order to clarify our understanding of HHMS.

Abstract
Comprehensive genomic profiling (CGP) of a metastatic liver tumor biopsy specimen suggested that the patient, who was initially diagnosed with cholangiocarcinoma, had colorectal cancer. The identification of both FBXW7 and APC mutations is deemed characteristic of colorectal cancer. Indeed, subsequent colonoscopy revealed sigmoid colon carcinoma that led to tumor resection followed by systemic chemotherapy. CGP is principally used to identify agents that might potentially benefit the patient. However, results must be interpreted carefully to ensure consistency with the initial diagnosis.

Abstract
Myeloid/natural killer (NK) cell precursor acute leukemia (MNKPL) has been described on the basis of its unique immunophenotype and clinical phenotype. However, there is no consensus on the characteristics for identifying this disease type because of its rarity and lack of defined distinctive molecular characteristics. In this study, multiomics analysis revealed that MNKPL is distinct from acute myeloid leukemia, T cell acute lymphoblastic leukemia, and mixed-phenotype acute leukemia (MPAL), and NOTCH1 and RUNX3 activation and BCL11B down-regulation are hallmarks of MNKPL. Although NK cells have been classically considered to be lymphoid lineage-derived, the results of our single-cell analysis using MNKPL cells suggest that NK cells and myeloid cells share common progenitor cells. Treatment outcomes for MNKPL are unsatisfactory, even when hematopoietic cell transplantation is performed. Multiomics analysis and in vitro drug sensitivity assays revealed increased sensitivity to l-asparaginase and reduced levels of asparagine synthetase (ASNS), supporting the clinically observed effectiveness of l-asparaginase.

Abstract
Background Left ventricular (LV) apical sparing by transthoracic echocardiography (TTE) has not been widely accepted to diagnose transthyretin amyloid cardiomyopathy (ATTR-CM), because it is time consuming and requires a level of expertise. We hypothesized that automatic assessment may be the solution for these problems. Methods-and-Results We enrolled 63 patients aged ≥70 years who underwent 99mTc-labeled pyrophosphate (99mTc-PYP) scintigraphy on suspicion of ATTR-CM and performed TTE by EPIQ7G, and had enough information for two-dimensional speckle tracking echocardiography at Kumamoto University Hospital from January 2016 to December 2019. LV apical sparing was described as a high relative apical longitudinal strain (LS) index (RapLSI). Measurement of LS was repeated using the same apical images with three different measurement packages as follows: (1) full-automatic assessment, (2) semi-automatic assessment, and (3) manual assessment. The calculation time for full-automatic assessment (14.7 ± 1.4 sec/patient) and semi-automatic assessment (66.7 ± 14.4 sec/patient) were significantly shorter than that for manual assessment (171.2 ± 59.7 sec/patient) (p < 0.01 for both). Receiver operating characteristic curve analysis showed that the area under curve of the RapLSI evaluated by full-automatic assessment for predicting ATTR-CM was 0.70 (best cut-off point; 1.14 [sensitivity 63%, specificity 81%]), by semi-automatic assessment was 0.85 (best cut-off point; 1.00 [sensitivity, 66%; specificity, 100%]) and by manual assessment was 0.83 (best cut-off point; 0.97 [sensitivity, 72%; specificity, 97%]). Conclusion There was no significant difference between the diagnostic accuracy of RapLSI estimated by semi-automatic assessment and that estimated by manual assessment. Semi-automatically assessed RapLSI is useful to diagnose ATTR-CM in terms of rapidity and diagnostic accuracy.

Abstract
Aberrant innate immune signaling in myelodysplastic syndrome (MDS) hematopoietic stem/progenitor cells (HSPCs) has been implicated as a driver of the development of MDS. We herein demonstrated that a prior stimulation with bacterial and viral products followed by loss of the Tet2 gene facilitated the development of MDS via up-regulating the target genes of the Elf1 transcription factor and remodeling the epigenome in hematopoietic stem cells (HSCs) in a manner that was dependent on Polo-like kinases (Plk) downstream of Tlr3/4-Trif signaling but did not increase genomic mutations. The pharmacological inhibition of Plk function or the knockdown of Elf1 expression was sufficient to prevent the epigenetic remodeling in HSCs and diminish the enhanced clonogenicity and the impaired erythropoiesis. Moreover, this Elf1-target signature was significantly enriched in MDS HSPCs in humans. Therefore, prior infection stress and the acquisition of a driver mutation remodeled the transcriptional and epigenetic landscapes and cellular functions in HSCs via the Trif-Plk-Elf1 axis, which promoted the development of MDS.

Abstract
Introduction Inherited DDX41 mutations cause familial predisposition to hematologic malignancies including acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), with the majority of DDX41 mutated MDS/AMLs described to date harboring germline DDX41 and co-occurring somatic DDX41 variants. DDX41-AMLs were shown to share distinguishing clinical features such as a late AML onset and an indolent disease associated with a favorable outcome. However, genotype-phenotype correlation in DDX41-MDS/AMLs remain poorly understood. Methods Here, we studied the genetic profile, bone marrow morphology and immunophenotype of 51 patients with DDX41 mutations. We further assessed the functional impact of ten previously uncharacterized DDX41 variants of uncertain significance. Results Our results demonstrate that MDS/AML cases harboring two DDX41 variants share specific clinicopathologic hallmarks that are not seen in other patients with monoallelic DDX41 related hematologic malignancies. We further showed that the features seen in these individuals with two DDX41 variants were concordant with biallelic DDX41 disruption. Discussion Here, we expand on previous clinicopathologic findings on DDX41 mutated hematologic malignancies. Functional analyses conducted in this study unraveled previously uncharacterized DDX41 alleles and further illustrate the implication of biallelic disruption in the pathophysiology of this distinct AML entity.

Abstract
Aims Left ventricular (LV) global longitudinal strain (GLS) (LV-GLS) is a strong and independent predictor of outcomes in patients with immunoglobulin light-chain (AL) cardiac amyloidosis. This study was performed to investigate whether right ventricular (RV) GLS (RV-GLS) provides prognostic information in patients with AL amyloidosis. Methods and results Among 74 patients who were diagnosed with AL cardiac amyloidosis at Kumamoto University Hospital from December 2005 to December 2022, 65 patients who had enough information for two-dimensional speckle tracking imaging and did not receive chemotherapy before the diagnosis of cardiac amyloidosis were retrospectively analysed. During a median follow-up of 359 days, 29 deaths occurred. In two-dimensional echocardiographic findings, LV-GLS, left atrium reservoir strain (LASr), and RV-GLS were significantly lower in the all-cause death group than in the survival group (LV-GLS: 8.9 ± 4.2 vs. 11.7 ± 3.9, P < 0.01; LASr: 9.06 ± 7.28 vs. 14.09 ± 8.32, P < 0.05; RV-GLS: 12.0 ± 5.1 vs. 16.8 ± 4.0, P < 0.01). Multivariable Cox proportional hazard analysis showed RV-GLS was significantly and independently associated with all-cause death in patients with AL cardiac amyloidosis (hazard ratio 0.85; 95% confidence interval, 0.77-0.94; P < 0.01). Receiver operating characteristic analysis showed that the area under the curve of RV-GLS for all-cause death was 0.774 and that the best cut-off value of RV-GLS was 14.5% (sensitivity, 75%; specificity, 72%). In the Kaplan-Meier analysis, patients with AL cardiac amyloidosis who had low RV-GLS (<14.5%) had a significantly higher probability of all-cause death (P < 0.01). Conclusion RV-GLS has prognostic value in patients with AL cardiac amyloidosis and provides greater prognostic power than LV-GLS and LASr.

Abstract
Chordoma is a rare malignant bone tumor arising from notochordal tissue. Conventional treatments, such as radical resection and high-dose irradiation, frequently fail to control the tumor, resulting in recurrence and re-growth. In this study, genetic analysis of the tumor in a 72-year-old male patient with refractory conventional chordoma of the skull base revealed a high tumor mutational burden (TMB) and mutations in the MSH6 and MLH1 genes, which are found in Lynch syndrome. The patient and his family had a dense cancer history, and subsequent germline genetic testing revealed Lynch syndrome. This is the first report of a chordoma that has been genetically proven to be Lynch syndrome. Chordomas usually have low TMB; however, this is an unusual case, because the TMB was high, and immune checkpoint inhibitors effectively controlled the tumor. This case provides a basis for determining the indications for immunotherapy of chordoma based on the genetic analysis. Therefore, further extensive genetic analysis in the future will help to stratify the treatment of chordoma.

Abstract
DDX41 mutation has been observed in myeloid malignancies including myelodysplastic syndromes and acute myeloid leukemia, but the underlying causative mechanisms of these diseases have not been fully elucidated. The DDX41 protein is an ATP-dependent RNA helicase with roles in RNA metabolism. We previously showed that DDX41 is involved in ribosome biogenesis by promoting the processing of newly transcribed pre-ribosomal RNA. To build on this finding, in this study, we leveraged ribosome profiling technology to investigate the involvement of DDX41 in translation. We found that DDX41 knockdown resulted in both translationally increased and decreased transcripts. Both gene set enrichment analysis and gene ontology analysis indicated that ribosome-associated genes were translationally promoted after DDX41 knockdown, in part because these transcripts had significantly shorter transcript length and higher transcriptional and translational levels. In addition, we found that transcripts with 5'-terminal oligopyrimidine motifs tended to be translationally upregulated when the DDX41 level was low. Our data suggest that a translationally regulated feedback mechanism involving DDX41 may exist for ribosome biogenesis.

Abstract
BACKGROUND The Japanese government introduced financial incentives to reduce nationwide antibiotic use in hospital settings. AIM This study aimed to determine whether the nationwide financial incentives for creating infection prevention and control (IPC) teams introduced in 2012 and antimicrobial stewardship (ASP) teams introduced in 2018 were associated with changes in antibiotic use and health resource utilization at a national level. METHODS We conducted time-series analyses and a difference-in-differences study consisting of 3,057,517 inpatients with infectious diseases from 472 medical facilities during fiscal years 2011-2018 using a nationally representative inpatient database in Japan. The primary outcome was the days of therapy (DOT) of antibiotic use per 100 patient-days (PDs). The secondary outcomes consisted of types of antibiotic used, health resource utilization, and mortality. RESULTS A total of 5,201,304 financial incentives were observed during 2012-2018, which resulted in a total of 12.1 billion JPY (≈110 million USD). Time-series analyses found decreasing trends in total antibiotic use (79.3-72.5 DOTs/100 PDs (8.6% reduction)) and carbapenem use (9.0-7.0 DOTs/100 PDs (7.8% reduction)) from 2011 to 2018 without adversely affecting other healthcare outcomes (e.g., mortality). In the difference-in-differences analyses, we did not observe meaningful changes in total antibiotic use between the incentivized and unincentivized hospitals for ASP teams, except for the northern part of Japan. No dose-response relationships were observed between the amount of financial incentives and reductions in antibiotic use during 2011-2019. CONCLUSIONS Further research and efforts are needed to accelerate antimicrobial stewardship in hospital settings in Japan.

Abstract
OBJECTIVES Many studies have shown a good prognostic association with a large number of lymph node dissections. However, most of these studies did not include patients who have received neoadjuvant chemotherapy. The purpose of this study was to verify the relationship between survival outcomes and the number of lymph nodes removed during radical cystectomy in patients with muscle-invasive bladder cancer in the era of neoadjuvant chemotherapy. METHODS This retrospective study considered patients who were diagnosed with clinical ≥T2N0M0 muscle-invasive bladder cancer and treated with radical cystectomy at the Nagoya University Hospital and affiliated hospitals from January 2004 to December 2019. We excluded patients who had a history of upper tract urothelial cancer or non-urothelial carcinoma. The association between prognosis and the number of lymph nodes removed was investigated. RESULTS We retrospectively enrolled a total of 477 patients. The mean number of lymph nodes dissected was 14. Two hundred and twenty-six patients (47.4%) received neoadjuvant chemotherapy. More extensive lymphadenectomy (≥15 lymph nodes) correlated with better 5-year overall survival across all patients (68% vs. 57%, p = 0.01). In patients who received neoadjuvant chemotherapy, there was no difference in overall survival according to the number of dissected lymph nodes (66% vs. 71%, p = 0.433). In patients who did not receive neoadjuvant chemotherapy, ≥15 lymph nodes dissected was associated with significantly better overall survival (70.3% vs. 46.9%, p < 0.01). CONCLUSIONS No association between more aggressive lymph node dissection and prognosis was found in patients who underwent neoadjuvant chemotherapy. Conversely, extended lymph node dissection is desirable for patients who have not received neoadjuvant chemotherapy.

Abstract
In myeloid malignancies including acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), patient selection and therapeutic strategies are increasingly based on tumor-specific genetic mutations. Among these, mutations in DDX41, which encodes a DEAD-box type RNA helicase, are present in approximately 2–5% of AML and MDS patients; this disease subtype exhibits a distinctive disease phenotype characterized by late age of onset, tendency toward cytopenia in the peripheral blood and bone marrow, a relatively favorable prognosis, and a high frequency of normal karyotypes. Typically, individuals with a loss-of-function germline DDX41 variant in one allele later acquire the p.R525H mutation in the other allele before overt disease manifestation, suggesting that the progressive decrease in DDX41 expression and/or function is involved in myeloid leukemogenesis.RNA helicases play roles in many processes involving RNA metabolism by altering RNA structure and RNA-protein interactions through ATP-dependent helicase activity. A single RNA helicase can play multiple cellular roles, making it difficult to elucidate the mechanisms by which mutations in DDX41 are involved in leukemogenesis. Nevertheless, multiple DDX41 functions have been associated with disease development. The enzyme has been implicated in the regulation of RNA splicing, nucleic acid sensing in the cytoplasm, R-loop resolution, and snoRNA processing.Most of the mutated RNA splicing-related factors in MDS are involved in the recognition and determination of 3’ splice sites (SS), although their individual roles are distinct. On the other hand, DDX41 is likely incorporated into the C complex of the spliceosome, which may define a distinctive disease phenotype. This review summarizes the current understanding of how DDX41 is involved in this unique myeloid malignancy.

Abstract
BACKGROUND The efficacy of anti-programmed celldeath protein 1 treatment in patients with urothelial carcinoma (UC) with molecular subtypes of histological variants has not been investigated. This study aimed to examine the impact of histological variants classified according to molecular subtypes on clinical outcomes in patients with platinum-resistant metastatic UC treated with pembrolizumab. PATIENTS AND METHODS Data of 168 patients with metastatic UC who received intravenous pembrolizumab after platinum-based chemotherapy between December 2017 and November 2020 were retrospectively reviewed. Relationships between histological variant type (basal or luminal molecular subtypes) and survival outcome and response to immunotherapy were examined. Clinicopathological factors were analyzed using the Cox proportional hazards model. RESULTS UC with histological variants was identified in 19 (11.3%) cases (basal subtype in 12; luminal subtype in 7). The median age of the patients was 72.5 years (range=40-89 years). The performance status was 0-1 in 151 (89.9%) patients. Liver metastasis was detected in 44 (26.2%) patients. The median progression-free survival was 3.5 months (range=0.5-34.3 months). Treatment with immune checkpoint inhibitors resulted in an overall mean survival (from the start of treatment) of 8.1 months (range=1.2-34.3 months). Patients with basal-type UC had significantly shorter progression-free survival and cancer-specific survival than those with pure UC (p=0.010 and p=0.035, respectively). A complete response was observed in eight patients (seven with pure UC, one with basal type). CONCLUSION The basal histological variant might be a potential prognostic indicator in patients with platinum-resistant metastatic UC treated with pembrolizumab.

Abstract
This study aimed to evaluate the utility of immunohistochemical staining of vascular Notch3 deposits in biopsied unfixed frozen skin samples from patients with suspected cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). We analyzed vascular Notch3 deposits in unfixed frozen skin biopsy samples obtained from 43 patients with suspected CADASIL by immunohistochemistry using antibodies against the extracellular domain (ECD) of Notch3. We also sequenced the NOTCH3 gene in all patients, as well as evaluated their symptoms and neuroimages. We found granular Notch3 ECD deposits in the vessel walls of unfixed frozen skin biopsy samples in 10 of the 43 suspected patients with CADASIL. All 10 cases with skin Notch3 ECD deposits also carried reported pathogenic variants in the NOTCH3 gene associated with CADASIL. NOTCH3 variants of unknown significance were found in the other four patients without vascular Notch3 ECD or granular osmiophilic material deposits in biopsied skin samples. The remaining 29 cases without vascular Notch3 ECD deposits did not have variants in the NOTCH3 gene. Immunohistochemical evaluation of vascular Notch3 ECD deposits in unfixed frozen biopsied skin samples may be useful for detecting Notch3 deposits in CADASIL.

Abstract
Upon binding double-stranded DNA (dsDNA), cyclic GMP-AMP synthase (cGAS) is activated and initiates the cGAS-stimulator of IFN genes (STING)-type I interferon pathway. DEAD-box helicase 41 (DDX41) is a DEAD-box helicase, and mutations in DDX41 cause myelodysplastic syndromes (MDSs) and acute myeloid leukemia (AML). Here, we show that DDX41-knockout (KO) cells have reduced type I interferon production after DNA virus infection. Unexpectedly, activations of cGAS and STING are affected in DDX41 KO cells, suggesting that DDX41 functions upstream of cGAS. The recombinant DDX41 protein exhibits ATP-dependent DNA-unwinding activity and ATP-independent strand-annealing activity. The MDS/AML-derived mutant R525H has reduced unwinding activity but retains normal strand-annealing activity and stimulates greater cGAS dinucleotide-synthesis activity than wild-type DDX41. Overexpression of R525H in either DDX41-deficient or -proficient cells results in higher type I interferon production. Our results have led to the hypothesis that DDX41 utilizes its unwinding and annealing activities to regulate the homeostasis of dsDNA and single-stranded DNA (ssDNA), which, in turn, regulates cGAS-STING activation. cGAS is activated by dsDNA. Singh et al. find DDX41 regulates cGAS activation through unwinding and annealing activities on dsDNA and ssDNA, respectively, and MDS/AML patient mutant R525H causes overactivation of innate immune response due to its unbalanced activities. This DDX41-cGAS-STING pathway may be related to molecular pathogenesis of MDS/AML.

Abstract
Background We aimed to clarify the predictive factors for left ventricular (LV) function after aortic valve replacement (AVR) in patients with aortic regurgitation (AR). Methods and results Among 555 patients who underwent AVR at our institution from January 2015 to December 2020, we enrolled 44 patients for whom only AVR (or AVR + aortic replacement) was performed. We defined LV dysfunction under any of the following criteria: LV ejection fraction (LVEF) <50 %, LV diastolic dimension >65 mm, LV systolic dimension (LVDs) >50 mm, or LVDs/body surface area > 25 mm/m2. Multivariable logistic regression analysis revealed high natural logarithm (ln) C-reactive protein (CRP) and low LVEF in the pre-AVR period significantly associated with LV dysfunction after AVR (ln CRP: odds ratio [OR] 4.15, 95 % confidence interval [CI] 1.44-11.98, p < 0.01; LVEF: OR 0.79, 95%CI 0.65-0.97, p < 0.05). Receiver-operating characteristic analysis revealed an area under curve of CRP and LVEF in the pre-AVR period for LV dysfunction after AVR of 0.84 and 0.83, respectively. Upon dividing the patients into four groups according to cutoff values of CRP (0.13 mg/dL) and LVEF (50 %) in the pre-AVR period, no patients (0/19) had LV dysfunction in the low CRP (<0.13 mg/dL) and high LVEF (≥50 %) group, and all patients (5/5) in the high CRP (≥0.13 mg/dL) and low LVEF (<50 %) group had LV dysfunction after AVR. Conclusion High CRP level was significantly and independently associated with LV dysfunction after AVR. Combination of CRP and LVEF values might be useful for predicting improvement in LV function after AVR.

Abstract
Myeloid malignancies with DDX41 mutations are often associated with bone marrow failure and cytopenia before overt disease manifestation. However, the mechanisms underlying these specific conditions remain elusive. Here, we demonstrate that loss of DDX41 function impairs efficient RNA splicing, resulting in DNA replication stress with excess R-loop formation. Mechanistically, DDX41 binds to the 5' splice site (5'SS) of coding RNA and coordinates RNA splicing and transcriptional elongation; loss of DDX41 prevents splicing-coupled transient pausing of RNA polymerase II at 5'SS, causing aberrant R-loop formation and transcription-replication collisions. Although the degree of DNA replication stress acquired in S phase is small, cells undergo mitosis with under-replicated DNA being remained, resulting in micronuclei formation and significant DNA damage, thus leading to impaired cell proliferation and genomic instability. These processes may be responsible for disease phenotypes associated with DDX41 mutations.

Methods and results Among 129 patients who were diagnosed with ATTRwt‐CM at Kumamoto University Hospital from December 2002 to December 2019, 113 patients who had enough information for two‐dimensional speckle tracking echocardiography were enrolled in this study. During a median follow‐up of 668 days, 28 cardiovascular deaths occurred. Compared with patients in the non‐event group, those in the cardiovascular death group were significantly older (81.5 ± 7.4 vs. 78.1 ± 6.1 years, P < 0.01), had a lower incidence of carpal tunnel syndrome (21% vs. 47%, P < 0.05), and had a higher high‐sensitivity cardiac troponin T [0.085 (0.063–0.105) vs. 0.049 (0.036–0.079) ng/mL, P < 0.01] and B‐type natriuretic peptide concentrations [419 (239–541) vs. 271 (155–462) pg/mL, P < 0.01] and lower estimated glomerular filtration rate (41.8 ± 15.4 vs. 53.4 ± 14.6 mL/min/1.73 m2, P < 0.01). Electrocardiography showed higher rate of a V1–V3 QS pattern (52% vs. 24%, P < 0.01) and complete left bundle branch block (27% vs. 6%, P < 0.01), and echocardiography showed a significantly lower peak LA strain rate during the contraction phase (0.16 ± 0.13 vs. 0.28 ± 0.27 S−1, P < 0.05), LA strain during the reservoir phase (LASr) (5.84 ± 2.41 vs. 8.22 ± 4.05%, P < 0.01), and peak LA strain rate during the reservoir phase (0.26 ± 0.09 vs. 0.33 ± 0.15 S−1, P < 0.05) in the cardiovascular death group than in non‐event group. By contrast, conventional echocardiographic findings were not significantly different between these two groups. After adjusting for conventional predictive factors of ATTRwt‐CM (age, high‐sensitivity cardiac troponin T and B‐type natriuretic peptide concentrations, and estimated glomerular filtration rate), multivariable Cox proportional hazard analyses showed that LASr was significantly and independently associated with cardiovascular death in patients with ATTRwt‐CM (odds ratio, 0.84; 95% confidence interval, 0.72–0.98; P < 0.05). After adjusting for age and echocardiographic findings associated with cardiovascular death (LA volume index and peak LA strain rate during the contraction phase), LASr was significantly and independently associated with cardiovascular death in patients with ATTRwt‐CM (odds ratio, 0.83; 95% confidence interval, 0.70–0.98; P < 0.05). Receiver operating characteristic curve analysis showed that the area under the curve of LASr for cardiovascular death was 0.686 and that the best cut‐off value of LASr was 6.69% (sensitivity, 62.4%; specificity, 64.3%). In the Kaplan–Meier analysis, patients with low LASr (<6.69%) had a significantly higher probability of total cardiovascular death (P < 0.05) and heart failure‐related hospitalization (P < 0.05). Conclusions Left atrial strain during the reservoir phase provides significant prognostic value in patients with ATTRwt‐CM even after adjusting for conventional predictive factors.

Abstract
Autosomal dominant sterile α motif domain containing 9 (Samd9) and Samd9L (Samd9/9L) syndromes are a large subgroup of currently established inherited bone marrow failure syndromes that includes myelodysplasia, infection, growth restriction, adrenal hypoplasia, genital phenotypes, and enteropathy (MIRAGE), ataxia pancytopenia, and familial monosomy 7 syndromes. Samd9/9L genes are located in tandem on chromosome 7 and have been known to be the genes responsible for myeloid malignancies associated with monosomy 7. Additionally, as IFN-inducible genes, Samd9/9L are crucial for protection against viruses. Samd9/9L syndromes are caused by gain-of-function mutations and develop into infantile myelodysplastic syndromes associated with monosomy 7 (MDS/-7) at extraordinarily high frequencies. We generated mice expressing Samd9LD764N, which mimic MIRAGE syndrome, presenting with growth retardation, a short life, bone marrow failure, and multiorgan degeneration. In hematopoietic cells, Samd9LD764N downregulates the endocytosis of transferrin and c-Kit, resulting in a rare cause of anemia and a low bone marrow reconstitutive potential that ultimately causes MDS/-7. In contrast, in nonhematopoietic cells we tested, Samd9LD764N upregulated the endocytosis of EGFR by Ship2 phosphatase translocation to the cytomembrane and activated lysosomes, resulting in the reduced expression of surface receptors and signaling. Thus, Samd9/9L is a downstream regulator of IFN that controls receptor metabolism, with constitutive activation leading to multiorgan dysfunction.

Abstract
Almost all genetic abnormalities involved in the occurrence and progression of myelodysplastic syndromes (MDS) and acute myeloid leukemia have been reported within the last decade. The molecular mechanisms of these genetic changes involved in causing dysfunctions in hematopoietic cells have also been clarified in recent years. For MDS, gene mutations of RNA splicing factors and cohesin complex have been shown to trigger not only aberrant RNA splicing or decreased chromatin insulation but also DNA damage response and transcriptional dysregulation through inefficient interaction between promoters and enhancers. Consequently, these newly identified disease-causing mechanisms may be considered potential therapeutic targets.

Abstract
Leukemic oncoproteins cause uncontrolled self-renewal of hematopoietic progenitors by aberrant gene activation, eventually causing leukemia. However, the molecular mechanism underlying aberrant gene activation remains elusive. Here, we showed that leukemic MLL fusion proteins associate with the HBO1 histone acetyltransferase (HAT) complex through their trithorax homology domain 2 (THD2) in various human cell lines. MLL proteins associated with the HBO1 complex through multiple contacts mediated mainly by the ING4/5 and PHF16 subunits in a chromatin-bound context where histone H3 lysine 4 tri-methylation marks were present. Of the many MLL fusions, MLL-ELL particularly depended on the THD2-mediated association with the HBO1 complex for leukemic transformation. The C-terminal portion of ELL provided a binding platform for multiple factors including AF4, EAF1, and p53. MLL-ELL activated gene expression in murine hematopoietic progenitors by loading an AF4/ENL/P-TEFb (AEP) complex onto the target promoters wherein the HBO1 complex promoted the association with AEP complex over EAF1 and p53. Moreover, the NUP98-HBO1 fusion protein exerted its oncogenic properties via interaction with MLL but not its intrinsic HAT activity. Thus, the interaction between the HBO1 complex and MLL is an important nexus in leukemic transformation, which may serve as a therapeutic target for drug development.

Abstract
Background: There are few reports on the current awareness and status of venous ultrasonography, including the number of specialists who perform this procedure, in a specific regional area in Japan. Methods and Results: This cross-sectional survey study was conducted in Kumamoto Prefecture from October 2018 to March 2019. Of the 366 medical institutions providing cardiology services in Kumamoto Prefecture, 259 (101 general hospitals, 158 small clinics) responded to our questionnaire. In 2017, 21,773 venous ultrasound tests were performed, 21,101 (97%) of which were performed in hospitals and only 672 (3%) were performed in clinics. Both the number of institutions performing venous ultrasounds and the number of tests performed increased over time. Although 317 medical staff in Kumamoto Prefecture were performing transthoracic echocardiography (TTE) when the questionnaires were collected, only 210 performed venous ultrasounds. Although 91% (61/67) of medical institutions could perform TTE within 30 min, only 77% (53/69) performed venous ultrasounds within 30 min. The number of venous ultrasounds per population×100 was largest in the Kumamoto and Kamimashiki areas (1.67) and smallest in the Kamoto area (0.05). Conclusions: This is the first report to reveal the current awareness and status of venous ultrasonography in a specific region in Japan. There are several problems to be overcome, such as a lack of venous ultrasound specialists and the regional disparity in venous ultrasounds in Kumamoto Prefecture.

Abstract
HOXA9 is often highly expressed in leukemias. However, its precise roles in leukemogenesis remain elusive. Here, we show that HOXA9 maintains gene expression for multiple anti-apoptotic pathways to promote leukemogenesis. In MLL fusion-mediated leukemia, MLL fusion directly activates the expression of MYC and HOXA9. Combined expression of MYC and HOXA9 induced leukemia, whereas single gene transduction of either did not, indicating a synergy between MYC and HOXA9. HOXA9 sustained expression of the genes implicated in the hematopoietic precursor identity when expressed in hematopoietic precursors, but did not reactivate it once silenced. Among the HOXA9 target genes, BCL2 and SOX4 synergistically induced leukemia with MYC. Not only BCL2, but also SOX4 suppressed apoptosis, indicating that multiple anti-apoptotic pathways underlie cooperative leukemogenesis by HOXA9 and MYC. These results demonstrate that HOXA9 is a crucial transcriptional maintenance factor that promotes MYC-mediated leukemogenesis, potentially explaining why HOXA9 is highly expressed in many leukemias.

Abstract
Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen that presents a serious risk to immunosuppressed individuals and other extremely vulnerable patients such as those in intensive care units. The emergence of multidrug-resistant Pseudomonas strains has increased the need for new antipseudomonal agents. In this study, a series of amino group-modified aminopenicillin derivatives was synthesized that have different numbers of carboxyl groups and structurally resemble carboxypenicillin-ureidopenicillin hybrids, and their antipseudomonal activities were evaluated. Among the derivatives synthesized, diethylenetriaminepentaacetic acid (DTPA)-modified amoxicillin (DTPA-Amox) showed potent antipseudomonal activity, not only against the laboratory strain PAO1 but also against clinically isolated Pseudomonas strains that were resistant to piperacillin and carbenicillin. DTPA-Amox had no obvious cytotoxic effects on cultured mammalian cells. In addition, in an in vivo model of leukopenia, DTPA-Amox treatment produced a moderate but statistically significant improvement in the survival of mice with P. aeruginosa strain PAO1 infection. These data suggest that polycarboxylation by DTPA conjugation is an effective approach to enhance antipseudomonal activity of aminopenicillins.

Abstract
[Purpose] We followed-up patients who underwent arthroscopic rotator cuff repair (ARCR) for 2 years to assess the prognosis of rotator cuff tears and compared the outcomes of the patients with and without re-rupture. We also examined the usefulness of Shoulder36, a self-assessment tool, for assessing the long-term prognosis in patients undergoing ARCR. [Participants and Methods] We included 28 patients who received occupational therapy pre- and post-ARCR between April 2012 and August 2015 and categorized them based on the occurrence of re-rupture. We followed-up on their prognoses for 2 years using physical examination and Shoulder36 assessment. [Results] Re-rupture occurred in five patients within 3 months of treatment. During the 2 year follow-up, the control group showed a significant improvement in pain and bi-directional active range of motion during physical assessment and in five out of six domains during Shoulder36 assessment. In contrast, the re-rupture group showed significant differences for only three domains of the Shoulder36 assessment twelve months after surgery. [Conclusion] We confirmed the long-term functional improvement and maintenance in the re-rupture group, suggesting that continued rehabilitation, compensatory movements, and detailed guidance on daily life activities are required for patients after ARCR. Furthermore, Shoulder36 can be useful for assessing the prognosis of patients with and without re-rupture.

Abstract
PURPOSE Synthetic non-absorbable mesh is used for elective inguinal hernia repair but is not commonly used for incarcerated or strangulated inguinal hernia requiring enterectomy to reduce the risk of surgical-site infection. This study aimed to evaluate the safety of synthetic non-absorbable mesh repair in patients with incarcerated or strangulated inguinal hernia requiring enterectomy versus non-mesh repair. METHODS We analyzed patients with incarcerated or strangulated inguinal hernia with enterectomy from April 2012 to March 2017 using a nationwide inpatient database in Japan. We conducted overlap propensity score-weighted analyses to compare surgical-site infection (SSI), duration of anesthesia, antibiotic use at > 3 days after surgery, postoperative hospital stay, and 30 day readmission. Two sensitivity analyses were performed. First, we compared the proportions of patients requiring wound culture at ≥ 3 days after surgery. Second, we performed overlap propensity score-weighted logistic regression analyses for surgical-site infection. RESULTS We identified 668 eligible patients, comprising 223 patients with mesh repair and 445 with non-mesh repair. Overlap propensity score-weighted analyses showed no significant differences between the mesh repair and non-mesh repair groups for SSI (2.5 vs. 2.8%, P = 0.79). Secondary outcomes did not differ significantly between the groups. Proportion of wound culture at ≥ 3 days after surgery was similar in the two groups (11.1 vs. 14.6%, P = 0.18). Logistic regression analysis showed no significant association between mesh repair and SSI (odds ratio, 0.93; 95% confidence interval, 0.34-2.57). CONCLUSION Synthetic non-absorbable mesh use may be safe for incarcerated or strangulated inguinal hernia requiring enterectomy.

Abstract
Idiopathic CD4+ lymphocytopenia (ICL) is the depletion of CD4+ lymphocytes to <300 cells/mm3 without human immunodeficiency virus infection or other causes of lymphocytopenia. ICL causes fatal infections; its etiology remains unclear and it lacks consensus regarding therapeutic options. We report the first patient with ICL who had a successful clinical course following a cord blood transplant (CBT). A 45-year-old woman was diagnosed with ICL and underwent partial hepatectomy for an abscess caused by the Mycobacterium avium complex. No specific gene alterations were detected through next generation sequencing-based evaluation. Following a reduced-intensity conditioning (RIC) regimen consisting of fludarabine, busulfan, and 4 Gy total body irradiation, a single-unit CBT was performed. Neutrophils were engrafted on day +14. CD4+ lymphocyte counts increased to over 300 cells/mm3 on day +436. After 75 months, she was alive without any sequelae. CBT with an RIC regimen could be a curable treatment option for ICL.

Abstract
BACKGROUND Although patients with schizophrenia have a higher risk of developing breast cancer than the general population, studies that have investigated postoperative complications after breast cancer surgery in patients with schizophrenia are scarce. This study examined associations between schizophrenia and short-term outcomes following breast cancer surgery. METHODS Patients who underwent surgery for stage 0-III breast cancer between July 2010 and March 2017 were identified from a Japanese nationwide inpatient database. Multivariable analyses were conducted to compare postoperative complications and hospitalization costs between patients with schizophrenia and those without any psychiatric disorder. Three sensitivity analyses were performed: a 1 : 4 matched-pair cohort analysis with matching for age, institution, and fiscal year at admission; analyses excluding patients with schizophrenia who were not taking antipsychotic medication; and analyses excluding patients with schizophrenia who were admitted to hospital involuntarily. RESULTS The study included 3660 patients with schizophrenia and 350 860 without any psychiatric disorder. Patients with schizophrenia had a higher in-hospital morbidity (odds ratio (OR) 1.37, 95 per cent c.i. 1.21 to 1.55), with more postoperative bleeding (OR 1.34, 1.05 to 1.71) surgical-site infections (OR 1.22, 1.04 to 1.43), and sepsis (OR 1.20, 1.03 to 1.41). The total cost of hospitalization (coefficient €743, 95 per cent c.i. 680 to 806) was higher than that for patients without any psychiatric disorder. All sensitivity analyses showed similar results to the main analyses. CONCLUSION Although causal inferences remain premature, multivariable regression analyses showed that schizophrenia was associated with greater in-hospital morbidity and higher total cost of hospitalization after breast cancer surgery than in the general population.

Abstract
Red blood cell (RBC) transfusion is an effective therapy for anemia, but repeated transfusions may cause iron overload-related damage to various organs. Iron chelation therapy, now widely available for patients who have received transfusions, is expected to reduce organ damage even in patients who received many transfusions. Therefore, determining when to start iron chelation therapy is important. In guidelines for iron chelation therapy, the serum ferritin level has been widely accepted as a practical marker for estimating iron overload. However, guidelines recommend multiple measurements of serum ferritin, because levels often fluctuate. Here, we investigated the usefulness of glycosylated ferritin as a marker of iron overload using a cohort consisted of 103 patients who had a total ferritin value over 1000 ng/mL. We found that the volume of RBCs transfused was clearly associated with the glycosylated ferritin level. We also found that acute inflammation, as represented by C-reactive protein values, was associated with increased non-glycosylated ferritin and that patients with hematopoietic diseases had higher glycosylated ferritin levels, possibly because of repeated RBC transfusions. We thus conclude that glycosylated ferritin may be an improved marker for predicting iron overload status.

Abstract
AIMS Hereditary transthyretin (ATTRv) amyloidosis is the most frequent and representative form of autosomal dominant hereditary systemic amyloidosis. Disease-modifying treatments of the disease are more effective during the early stages, and we require biomarkers to detect early pathological changes for prompt diagnosis. This study aimed to investigate whether plasma growth differentiation factor 15 (GDF-15) levels could aid detection of early pathological changes in ATTRv amyloidosis. METHODS AND RESULTS We retrospectively studied 32 patients with ATTRv amyloidosis, eight asymptomatic TTR mutation carriers, and eight healthy volunteers. We evaluated plasma GDF-15 levels in these subjects as related to levels of brain natriuretic peptide and high-sensitivity troponin T, echocardiographic features, 99m Tc-pyrophosphate (PYP) scans, and cardiac magnetic resonance imaging findings. Plasma GDF-15 levels significantly increased even in asymptomatic TTR mutation carriers compared with healthy volunteers (P < 0.01). Plasma GDF-15 levels were significantly correlated with plasma brain natriuretic peptide values (P < 0.01), serum high-sensitivity troponin T values (P < 0.05), and interventricular septal thickness at end-diastole (P < 0.01) in patients with ATTRv amyloidosis. Plasma GDF-15 levels in patients with PYP-positive ATTRv amyloidosis were significantly higher than those in patients with PYP-negative ATTRv amyloidosis (P < 0.01). Plasma GDF-15 levels in patients with late gadolinium enhancement-positive ATTRv amyloidosis were significantly higher than those in patients with late gadolinium enhancement-negative ATTRv amyloidosis (P < 0.01). Groups of patients with different TTR genotypes manifested different plasma GDF-15 levels. CONCLUSIONS Growth differentiation factor 15 may reflect early pathological changes of ATTRv amyloidosis.

Abstract
BACKGROUND Collagen disease is an important cause of aortic regurgitation (AR). Although aortic valve surgery is recommended for patients with AR and depressed left ventricular (LV) function, there have been few reports about risk factors for LV dysfunction in patients with AR concomitant with collagen disease. METHODS AND RESULTS We conducted this study at Kumamoto University Hospital in Japan. A total of 41 patients who had moderate to severe AR and concomitant collagen disease between January 2014 and December 2019 were enrolled. With regard to baseline characteristics, there were no significant differences in the type of collagen disease or El Khoury class between patients with preserved LV function and those with reduced LV function. B-type natriuretic peptide (375.2 [257.9-3852.6]pg/ml vs. 64.0 [33.3-133.6]pg/ml, p < 0.01), C-reactive protein (CRP) levels (2.00 [1.24-9.14]mg/dl vs. 0.19 [0.06-0.52]mg/dl, p < 0.01) and neutrophil-to-lymphocyte ratio (7.94 [3.30-9.98] vs. 3.94 [1.83-5.58], p < 0.05) were significantly higher, and hemoglobin level (10.7 ± 1.6 g/dl vs. 12.2 ± 1.8 g/dl, p < 0.05) was significantly lower in patients with reduced LV function than in those with preserved LV function. There were no significant differences in any variables associated with severity and features of AR. Multivariable logistic regression analysis showed that high CRP levels (≥1.0 mg/dl) were independently and significantly associated with LV dysfunction in patients with AR and collagen disease, even after adjusting for the severity of AR (odds ratio: 95.7; 95% confidence interval: 4.6-1990.4, p < 0.01). CONCLUSIONS Uncontrolled inflammation, represented as high CRP levels, is an important marker for LV dysfunction in patients with AR and collagen disease.

Abstract
Background:
Using transthoracic echocardiography, including 2D speckle tracking imaging (STI), this study examined cardiac function after domino liver transplantation (DLT) with liver grafts explanted from patients with hereditary amyloidogenic transthyretin amyloidosis. Methods and Results:
In all, 14 patients who underwent DLT at Kumamoto University Hospital and for whom 2D STI information was available were enrolled in the study; time-dependent echocardiographic changes were evaluated in 7. Although left ventricular (LV) systolic and diastolic function did not differ between the pre- and post-DLT periods (mean [±SD] 5.4±1.0 years after DLT), there were significant (P<0.05 for all) increases in the post- vs. pre-DLT period in basal longitudinal strain (LS; −13.4±2.3 vs. −19.3±4.4), relative apical LS index (=apical LS/[basal LS+mid LS]; 0.75±0.20 vs. 0.58±0.08), and LV ejection fraction/global LS (3.91±0.58 vs. 3.06±0.44). Age at the time of DLT was significantly higher in the group with impaired (>−14%) than preserved basal LS (57.2±3.5 vs. 39.6±16.0 years; P<0.05). When control subjects (n=14) were added to the enrolled DLT recipients, multivariable logistic regression analysis revealed that a history of DLT was significantly associated with impaired basal LS (>−14%; odds ratio 28.39, 95% confidence interval 1.89–427.45, P<0.05). Conclusions:
LV systolic and diastolic function was preserved in the long term after DLT. However, 2D STI revealed subtle cardiac dysfunction in DLT recipients, which may be an early manifestation of cardiac amyloidosis.

Abstract
OBJECTIVES To investigate the prevalence of postoperative complications after transvaginal mesh prolapse surgery, and whether modified transvaginal mesh prolapse surgery (without transobturator arms or posterior mesh) has less prevalence of mesh exposure compared with conventional transvaginal mesh prolapse surgery. METHODS Medical charts were retrospectively examined for 2648 patients who underwent transvaginal mesh prolapse surgery in a general hospital (2006-2017). Conventional transvaginal mesh prolapse surgery (Prolift-type, n = 2258) was used, with a shift from 2015 to modified transvaginal mesh prolapse surgery (Uphold-type, n = 330). Patients were instructed to have >2 years of follow up and to report if they had problems regarding the operation. RESULTS The prevalence of mesh exposure was 34 out of 2648 (1.28%); 18 vagina (0.68%), 10 bladder (0.38%), two ureter (0.08%) and four rectum (0.15%). The modified transvaginal mesh prolapse surgery group had only one case with vaginal exposure. Vaginal exposure was managed transvaginally or followed by observation. Rectal exposure was managed transvaginally without colostomy. Bladder exposure was managed by transurethral resection with saline. Open ureterocystostomy was carried out to treat ureteral exposure. In the conventional transvaginal mesh prolapse surgery group, three cases of ureteral stenosis and one case with vaginal evisceration of the small intestine were managed transvaginally. The prevalence of postoperative chronic pain was 13 out of 2648 (0.49%; with one patient in the modified transvaginal mesh prolapse surgery group). The patients underwent pharmacotherapy, and one patient underwent additional surgical treatment. CONCLUSIONS The reoperation rate as a result of complications after transvaginal mesh prolapse surgery seems to be low. The reoperation rate as a result of prolapse recurrence is also low. A shift from conventional transvaginal mesh prolapse surgery to modified transvaginal mesh prolapse surgery might contribute to a further decrease in the risk of complications.

Abstract
BACKGROUND We previously reported that a high score (2 or 3 points) according to the Kumamoto criteria, a combination of high-sensitivity cardiac troponin T (hs-cTnT) ≥0.308 ng/mL, the length of QRS ≥ 120 ms in electrocardiogram, and left ventricular (LV) posterior wall thickness ≥ 13.6 mm, increases the pretest probability of 99m Tc-labeled pyrophosphate (99m Tc-PYP) scintigraphy in patients with suspected transthyretin amyloid cardiomyopathy (ATTR-CM). However, some patients with a low score (0 or 1 point) show positive findings on 99m Tc-PYP scintigraphy. Therefore, we evaluated the usefulness of additional examinations, including echocardiographic assessment of myocardial strain, to raise the pretest probability of 99m Tc-PYP scintigraphy for these patients. METHODS AND RESULTS We examined 109 consecutive patients aged ≥70 years with low scores according to the Kumamoto criteria who underwent 99m Tc-PYP scintigraphy. Nineteen patients (17%) had positive 99m Tc-PYP scintigraphy findings. The relative apical longitudinal strain (LS) index (apical LS/ basal LS + mid LS) (RapLSI) was significantly higher in patients with positive than negative 99m Tc-PYP scintigraphy findings (1.04 ± 0.37 vs 0.70 ± 0.28, P < .01). Multivariable logistic regression analysis revealed that a high RapLSI (≥1.04) was significantly associated with 99m Tc-PYP positivity (odds ratio, 14.14; 95% confidence interval, 3.36-59.47; P < .01). The sensitivity, specificity, and accuracy of the diagnostic model using the RapLSI for identification of 99m Tc-PYP positivity were 53%, 94%, and 87%, respectively. CONCLUSIONS A high RapLSI can raise the pretest probability of 99m Tc-PYP scintigraphy in patients with a low score according to the Kumamoto criteria. The RapLSI can assist clinicians in determining strategies for these patients.

Abstract
Objective To examine the age in months at which infants visited outpatient clinics or emergency rooms for the first time for nonfatal injuries and to identify risk factors for the occurrence of these injuries. Study design Retrospective cohort study. Methods We used a health insurance claims database in Japan. Infants born between April 2012 and December 2014 were identified and followed until 12 months of age. We identified their first visit to outpatient clinics or emergency rooms because of nonfatal injuries (wounds/fractures, foreign bodies, and burns). Cox regression analysis was used to examine the association of nonfatal injuries with infants’ sex, birth order, and parental age. Results We identified 46,431 eligible infants. Of these, 7606 (16.4%) were brought to an outpatient clinic or emergency room for nonfatal injuries within 12 months of birth. Of the 7,606, 21.7% were aged ≤4 months and 44.7% ≤ 7 months. First-born infants were more likely to have wounds/fractures and burns. Conclusion One-fifth of first nonfatal infant injuries occurred within 4 months of age. Healthcare providers should provide early education about injury prevention, especially to caregivers of first-born infants. Nonfatal injuries within first year of birth occurred in 16% of infants. 22% of first injuries occurred within 4 months of birth. First-born infants were more likely to have wounds/fractures and burns.

Abstract
Infections caused by Aspergillus species are often life-threatening. Drugs effective for Aspergillus infection are limited. Voriconazole is one of the most important drugs, however, considerable portion of patients experience liver toxicity and have to stop the drug administration. We frequently experience liver toxicity even though the serum concentration of voriconazole is within the target range. Historically, in some life-threatening situations like tuberculosis, where a suitable alternative is unavailable, rechallenge has been attempted. However, there have been no report on the rechallenge of voriconazole. We report cases of successful re-administration of voriconazole after liver toxicity.

Abstract
Background:
There are few reports on current awareness and status of transthoracic echocardiography (TTE), including the actual performance rate according to echocardiographic guidelines, in a specific area or region. Methods and Results:
This cross-sectional survey study was conducted in Kumamoto Prefecture from October 2018 to March 2019. There are 366 medical institutions advocating cardiology in Kumamoto Prefecture. Of these, 259 (101 hospitals and 158 clinics) returned questionnaires regarding TTE. In all, 150,570 TTEs were performed in 2017. Of these, 132,771 (88%) were performed in hospitals and 17,799 (12%) were performed in clinics. Physicians performed only 5% of TTEs, whereas sonographers performed 86%. Although the modified Simpson method was performed in 90% of hospitals, 3-dimensional echocardiography was performed in only 2% of hospitals. In addition, the left atrial volume index was not examined in approximately 60% of hospitals, and the mean E/E′ ratio was not examined in 80% of hospitals. Multivariable logistic regression analysis revealed that having a Fellow of the Japan Society of Ultrasonic in Medicine was significantly and independently associated with guideline-oriented TTE (odds ratio 9.43; 95% confidence interval 1.22–72.71, P<0.05). Conclusions:
The rate of echocardiographic measurements performed according to echocardiographic guidelines is exceptionally low in Kumamoto Prefecture. Sufficient dissemination of echocardiographic guidelines may be important in improving this rate.

Abstract
To detect vascular Notch3 extracellular domain aggregates in CADASIL, we developed a novel dot-blot assay with both autopsy and biopsy skin samples. We obtained samples from 11 patients with CADASIL and 12 control patients, and we performed dot-blot analyses by using sequential biochemical tissue extractions with three different antibodies against specific regions of the Notch3 extracellular domain. We also analyzed clinical features and vascular accumulations of Notch3 by immunohistochemistry. Via the dot-blot assay with the antibody against the C-terminal region of the Notch3 extracellular domain, we successfully detected Notch3 extracellular domain aggregates in skin tissue homogenates obtained from patients with CADASIL. Our novel method may therefore aid the diagnosis of CADASIL.

Abstract
Human papilloma virus (HPV)-associated oropharyngeal cancer (OPC) is an independent tumour type with regard to cellular, biological, and clinical features. The use of non-invasive biomarkers such as circulating tumour DNA (ctDNA) may be relevant in early diagnosis and eventually improve the outcomes of patients with head and neck squamous cell carcinoma (HNSCC). Genome-wide discovery using RNA sequencing and reduced representation bisulfite sequencing yielded 21 candidates for methylation-targeted genes. A verification study (252 HNSCC patients) using quantitative methylation-specific PCR (Q-MSP) identified 10 genes (ATP2A1, CALML5, DNAJC5G, GNMT, GPT, LY6D, LYNX1, MAL, MGC16275, and MRGPRF) that showed a significant increase recurrence in methylation groups with OPC. Further study on ctDNA using Q-MSP in HPV-associated OPC showed that three genes (CALML5, DNAJC5G, and LY6D) had a high predictive ability as emerging biomarkers for a validation set, each capable of discriminating between the plasma of the patients from healthy individuals. Among the 42 ctDNA samples, methylated CALML5, DNAJC5G, and LY6D were observed in 31 (73.8%), 19 (45.2%), and 19 (45.2%) samples, respectively. Among pre-treatment ctDNA samples, methylated CALML5, DNAJC5G, and LY6D were observed in 8/8 (100%), 7/8 (87.5%), and 7/8 (87.5%) samples, respectively. Methylated CALML5, DNAJC5G, and LY6D were found in 2/8 (25.0%), 0/8 (0%), and 1/8 (12.5%) of the final samples in the series, respectively. Here, we present the relationship between the methylation status of three specific genes and cancer recurrence for risk classification of HPV-associated OPC cases. In conclusion, ctDNA analysis has the potential to aid in determining patient prognosis and real-time surveillance for disease recurrences and serves as an alternative method of screening for HPV-associated OPC.

Abstract
Abstract
Background
The aim of this study was to compare perioperative outcomes of urgent colectomy and placement of a self-expanding metallic stent followed by colectomy for patients with malignant right colonic obstruction. Right-sided malignant obstruction is less common than left-sided. Stenting for malignant left colonic obstruction has been reported to reduce postoperative complications. However, the impact of stenting for malignant right colonic obstruction remains undefined.
Methods
The study included patients with right-sided malignant obstruction or stenosis undergoing colectomy between April 2012 and March 2017 identified from a nationwide database. Propensity score matching analysis was used to compare mortality and morbidity rates, proportion receiving a stoma and postoperative stay between urgent colectomy and stent groups.
Results
From 9572 patients, 1500 pairs were generated by propensity score matching. There was no significant difference in in-hospital mortality between the urgent colostomy and stent groups (1·6 versus 0·9 per cent respectively; P = 0·069). Complications were more common after urgent colectomy than stenting (22·1 versus 19·1 per cent; P = 0·042). Surgical-site infection was more likely with urgent colectomy (7·1 versus 4·4 per cent; P = 0·001). There was no significant difference between the two groups in anastomotic leakage (3·8 versus 2·6 per cent; P = 0·062). The proportion of patients needing a stoma was higher with urgent colectomy than primary treatment with stents (5·1 versus 1·7 per cent; P < 0·001). Postoperative stay was longer after urgent colectomy (15 versus 13 days; P < 0·001).
Conclusion
Stenting followed by colectomy in patients with malignant right colonic obstruction may provide more favourable perioperative outcomes than urgent colectomy.

Abstract
Genetic testing based on next-generation sequencing (NGS) analysis has recently been used to diagnose hereditary diseases. In this study, we explored the usefulness of our custom amplicon panel that targeted 23 genes related to hereditary tumors given in the American College of Medical Genetics and Genomics recommendations. We applied our custom NGS panel to samples from 12 patients previously diagnosed by Sanger sequencing as having the diseases or diagnosed clinically by meeting the diagnostic criteria in this study. Our gene panel not only successfully identified all variants detected by Sanger sequencing but also identified previously unrecognized variants that resulted in confirmation of the disease, or even in the revision of the diagnosis. For instance, a patient identified with an SDHD gene mutation actually had von Hippel-Lindau (VHL) syndrome, as determined by the presence of a pathogenic VHL gene variant. We also identified false-positive results that were generated by amplification of genome regions that are not intended to be investigated. In conclusion, NGS-based amplicon sequencing is a highly effective method to detect germline variants, as long as they are also carefully reviewed by manual inspection.

Abstract
Background Hepatocellular carcinoma (HCC) with tumour thrombus (TT) in the inferior vena cava (IVC) or right atrium (RA) is a rare advanced disease state with a poor prognosis. The aim of this study was to examine survival after surgical resection. Methods Patients with HCC and TT of either the IVC or RA, who underwent liver resection between February 1997 and July 2017, were included. Their short‐ and long‐term outcomes and surgical details were analysed retrospectively. Results Thirty‐seven patients were included; 16 patients had TT in the IVC below the diaphragm, eight had TT in the IVC above the diaphragm, and 13 had TT entering the RA. Twelve patients had advanced portal vein TT (portal vein invasion (Vp) greater than Vp3 and Vp4), ten had bilobar disease, and 12 had extrahepatic disease. There were no in‐hospital deaths, although two patients died within 90 days. Median survival did not differ between patients who had resection with curative intent (18·7 months) and those with residual tumour in the lung only (20·7 months), but survival was poor for patients with residual tumour in the liver (8·3 months). Conclusion Liver resection with thrombectomy for advanced HCC with TT in the IVC or RA is safe and feasible, leading to moderate survival.

Abstract
BACKGROUND The collagen type IV alpha 1 chain (COL4A1) is an essential component of the basement membrane in small vessels. Pathogenic variants in COL4A1 cause perinatal cerebral hemorrhages in an autosomal-dominant fashion. However, little is known about the long-term outcomes of patients with mildly affecting COL4A1 mutations. CASE REPORT We report a 17-year-old boy, who presented with recurrent intracranial hemorrhages in the periventricular white matter. He had been followed-up as a child with cerebral palsy bearing intracranial calcifications, developmental delay and epilepsy. Screening tests in infancy provided negative results for intrauterine infections. Severe motor and cognitive deficits persisted after admission. Carbazochrome was introduced on day 19 of admission, which appeared to prevent extension and reactivation of cerebral hemorrhages for over 6 months after discharge. RESULTS Targeted sequencing of NOTCH3 and TREX1 excluded causal mutations in these genes. The whole-exome sequencing revealed that he carried a de novo mutation in COL4A1 (p.Gly696Ser). An overview of the literature for 345 cases with COL4A1 mutations supported evidence that p.Gly696Ser is associated with the unique phenotype of late-onset hemorrhage among patients with COL4A1-associated cerebral angiopathy. CONCLUSIONS This case first demonstrates that infants with COL4A1-associated leukoencephalopathy and calcifications have a risk for developing the rupture of small vessels in the cerebral white matter after 10 years of age.
