Abstract
BACKGROUND Although flexible laryngoscopy (FL) is the reference modality for diagnosing vocal cord paralysis (VCP), FL involves patient discomfort and insertion intolerance. Dynamic digital radiography (DDR) with high spatial and temporal resolution is easier to use and less invasive when evaluating VCP. METHODS Seventy-eight patients underwent FL and DDR before and after neck surgery. Qualitative and quantitative vocal cord movement (VCM) evaluations were conducted. Patients with postoperative VCP were followed-up regularly. RESULTS DDR exhibited diagnostic performance with 67% sensitivity and 100% specificity. The cutoff for VCM was 2.4 mm, with DDR exhibiting 100% sensitivity and 78% specificity. All cords with transient VCP had positive VCM at both 3 weeks and 2 months. Additionally, 50% and 75% of cords with permanent VCP had negative VCM at 3 weeks and 2 months, respectively. CONCLUSIONS DDR is promising for the diagnosis of postoperative VCP and early prediction of permanent postoperative VCP.

Abstract
BACKGROUND Secondary pneumothorax, which occurs most commonly in the elderly, is caused by underlying diseases. Cardiac dysfunction and other organ inefficiencies may render surgical repair impossible. Such non-operative and poor-risk cases are targets for pleurodesis, which involves the instillation of chemicals or irritants to the thoracic cavity through injection, bronchoscopic bronchial occlusion, or other procedures. Sterile graded talc has been used for pleurodesis mainly in Europe and the United States; however, only a few studies and case series investigating this topic have been published. This study evaluates the efficacy and safety of talc slurry pleurodesis. METHODS Patients with inoperable secondary intractable pneumothorax, who were not candidates for surgical repair, were recruited. Four grams of sterilized talc was suspended in 50 mL of physiological saline and injected through a tube into the pleural cavity. Additional 50 mL of saline was subsequently injected through the same channel to clean the residual saline in the injection tube. Another additional talc instillation was allowed to control persistent air leakage. The primary endpoint was the proportion of drainage tube removal within 30 days after talc pleurodesis. RESULTS Thirty-one patients were included in this study. In 23 out of 28 patients, the drainage tube could be removed within 30 days of talc instillation (82.1 %, 95 % CI = 63.1-93.9), exceeding the threshold of 36.0 % (p < 0.0001). The most common event was pain (11/28 patients, 39.3 %). CONCLUSIONS Talc slurry pleurodesis is effective for intractable secondary pneumothorax, with minor side effects.

Abstract
Robotic-assisted thoracoscopic surgery (RATS) is widely performed in thoracic surgery. The open-thoracotomy-view approach (OTVA) is one approach in RATS lung resection. OTVA is a good surgical approach that provides the same field of view as that with open thoracotomy and allows active participation of the assistant. However, the OTVA has certain limitations compared with other approaches, such as difficulty placing a robotic arm in the lower intercostal space, the assistant port is positioned further from the hilum, and CO2 insufflation is required. We have made some modifications to the OTVA by placing one of the robotic arms in the lower intercostal space, which enhances the operability for the surgeon without the need for CO2 insufflation. Additionally, by positioning the assistant port between the robotic arms, the assistant is closer to the hilum, and there is no requirement for a closed port owing to the absence of CO2 insufflation, resulting in improved performance by the assistant. Therefore, for the assistant to perform well, it is necessary to make modifications to the OTVA to widen the typically narrow space between the robotic arms. We performed lung resection using our modified 4-port 3-arm OTVA method in 20 patients from June 2022 to July 2023. Although we have not used our modified OTVA in a large number of cases, we have not observed critical issues to date. In this report, we introduce our modified OTVA as an option in RATS for lung resection.

Abstract
Considering the occurrence of serious heart failure in a gene knockout mouse of PIP5Kγ and in congenital abnormal cases in humans in which the gene was defective as reported by others, the present study attempted to localize PIP5Kγ in the heart during prenatal stages. It was done on the basis of the supposition that phenotypes caused by gene mutation of a given molecule are owed to the functional deterioration of selective cellular sites normally expressing it at significantly higher levels in wild mice. PIP5Kγ-immunoreactivity was the highest in the heart at E10 in contrast to almost non-significant levels of the immunoreactivity in surrounding organs and tissues such as liver. The immunoreactivity gradually weakened in the heart with the prenatal age, and it was at non-significant levels at newborn and postnatal stages. Six patterns in localization of distinct immunoreactivity for PIP5Kγ were recognized in cardiomyocytes: (1) its localization on the plasma membranes and subjacent cytoplasm without association with short myofibrils and (2) its localization on them as well as short myofibrils in association with them in cardiomyocytes of early differentiation at E10; (3) its spot-like localization along long myofibrils in cardiomyocytes of advanced differentiation at E10; (4) rare occurrences of such spot-like localization along long myofibrils in cardiomyocytes of advanced differentiation at E14; (5) its localization at Z-bands of long myofibrils; and (6) its localization at intercellular junctions including the intercalated discs in cardiomyocytes of advanced differentiation at E10 and E14, especially dominant at the latter stage. No distinct localization of PIP5Kγ-immunoreactivity of any patterns was seen in the heart at E18 and P1D. The present finding suggests that sites of PIP5Kγ-appearance and probably of its high activity in cardiomyocytes are shifted from the plasma membranes through short myofibrils subjacent to the plasma membranes and long myofibrils, to Z-bands as well as to the intercalated discs during the mid-term gestation. It is further suggested that PIP5Kγ is involved in the differentiation of myofibrils as well as intercellular junctions including the intercalated discs at later stages of the mid-term gestation. Failures in its involvement in the differentiation of these structural components are thus likely to cause the mid-term gestation lethality of the mutant mice for PIP5Kγ.

Abstract
PURPOSE Frailty is characterized by fragility and decline in physical, mental, and social activities; it is commonly observed in older adults. No studies have reported frailty status changes between the preoperative and postoperative periods, including mental and cognitive factors. Therefore, this study investigated frailty factors, including mental and cognitive functions, that change after non-cardiac surgery in older adults. METHODS Patients aged ≥ 75 years who underwent non-cardiac surgery were surveyed using five tools (Eastern Cooperative Oncology Group-Performance Status (PS); handgrip strengths; Japan-Cardiovascular Health Study index (J-CHS index); Mini-Mental State Examination (MMSE); and Geriatric Depression Scale) for comprehensive evaluation of perioperative functions. The results before surgery, at discharge, and during follow-up at the outpatient clinic were compared. RESULTS Fifty-three patients with a median age of 80 (IQR, 77-84) years were evaluated. MMSE scores did not change during the perioperative period. The PS and J-CHS index worsened significantly at discharge and did not improve at the outpatient clinic follow-up. The dominant handgrip strength decreased after surgery (p < 0.001) but improved during follow-up. Additionally, nondominant handgrip strength decreased after surgery (p < 0.001) but did not recover as much as the dominant handgrip strength during follow-up (p = 0.015). CONCLUSION Changes in physical frailty and mental and cognitive functions were not identical perioperatively in older adult patients undergoing non-cardiac surgery. Physical frailty did not improve 1 month after surgery, mental function recovered early, and cognitive function did not decline. This study may be important for frailty prevention in older adult patients.

Abstract
PURPOSE HER2-positive breast cancer has a high chance of achieving pathological complete response when HSD17B4, responsible for peroxisomal β-oxidation of very long-chain fatty acids (VLCFA) and estradiol, is methylation-silenced. Here, we aimed to identify the underlying molecular mechanism. METHODS Using a HER2-positive breast cancer cell line, BT-474, control and knock-out (KO) clones were obtained. Metabolic characteristics were analyzed using a Seahorse Flux analyzer. RESULTS HSD17B4 KO suppressed cellular proliferation, and enhanced sensitivity to lapatinib approximately tenfold. The KO led to accumulation of VLCFA and a decrease of polyunsaturated fatty acids (PUFAs), such as docosahexaenoic acid (DHA) and arachidonic acid. HSD17B4 KO increased Akt phosphorylation, possibly via decreased DHA, and genes involved in oxidative phosphorylation (OxPhos) and electron transport chain (ETC) were upregulated. Increased mitochondrial ATP production in the KO cells was confirmed by extracellular flux analyzer. Increased OxPhos led to severe dependence of the KO cells on pyruvate from glycolysis. Suppression of glycolysis by lapatinib led to severe delayed suppression of OxPhos in KO cells. CONCLUSION HSD17B4 KO in BT-474 cells caused a decrease of PUFAs, increased Akt phosphorylation, enhanced glucose dependence of OxPhos, and increased sensitivity to inhibition of HER2, upstream of Akt. This mechanism may be applicable to other HER2-positive glucose-dependent breast cancer cells with HSD17B4 silencing.

Abstract
BACKGROUND Distinguishing the histological types of lung cancer is essential for determining treatment strategies in clinical practice. In this study, cytomorphological characteristics and proliferative activities were compared among histological types of lung cancer by cytomorphometric and flow cytometric analyses using liquid-based cytology (LBC) samples. METHODS Scraped LBC samples from 73 surgically resected specimens were collected between August 2018 and November 2019. Papanicolaou-stained and paired Ki-67-stained slides were used for cytomorphometric analyses. Another sample for each case was analyzed using a flow cytometric system (LC-1000). The cell proliferation index (CPIx) was calculated to evaluate proliferative activity. RESULTS In total, 73 cases, including cases of adenocarcinoma (n = 53), squamous cell carcinoma (n = 14), small cell carcinoma (n = 1), large cell neuroendocrine carcinoma (NEC; n = 3), and pleomorphic carcinoma (n = 2) were evaluated. Small cell carcinoma and large cell NEC were categorized into a single group, NEC. The adenocarcinoma group tended to have a larger nuclear area and longer perimeter than other histological types. The NEC group had a considerably higher Ki-67 labeling index and significantly higher CPIx than other histological types (p = .030). A significant positive correlation was observed between the Ki-67 labeling index and CPIx for all cases (r = 0.362, p = .002). CONCLUSION The Ki-67 labeling index and flow cytometric analyses focus on proliferative activity for the distinction of histological types of lung cancer, thereby guiding clinical decision-making.

Abstract
OBJECTIVES This study aimed to compare the real-world outcomes of segmentectomy and lobectomy for lung cancer after adjusting for background factors and the extent of lymphadenectomy. METHODS This retrospective cohort study used a nationwide database in Japan. The data of patients with clinical stage 0/IA lung cancer who underwent segmentectomy or lobectomy between 2017 and 2019 were retrieved. Short-term postoperative outcomes were compared between the segmentectomy and lobectomy groups using propensity score-matched analysis. RESULTS In the total cohort of 59 663 patients, 11 975 and 47 688 patients were in the segmentectomy and lobectomy groups, respectively. After propensity score matching, 8426 matched patients from each group were retrieved. All confounders including age, sex, comorbidities, smoking history, respiratory function, tumour size, clinical stage, affected lobe and extent of lymphadenectomy were appropriately adjusted. The overall complication rate and the cardiopulmonary complication rate were lower in the segmentectomy group than in the lobectomy group (8.5% vs 11.2%, P < 0.001 and 7.5% vs 10.3%, P < 0.001, respectively). The incidence of prolonged air leak was also lower after segmentectomy than after lobectomy (3.6% vs 5.3%). Surgical mortality, operative time and blood loss volume were comparable between the 2 groups. CONCLUSIONS The postoperative complication rate was lower with segmentectomy than with lobectomy for early-stage lung cancer.

Abstract
Abstract
Background
Although the impact of new technology on the workplace has been discussed for many years, little has been reported regarding the effect of new technology in nursing homes. The aim of the research was to test the effect of a safety monitoring device on night-time work patterns.
Methods
A monitoring sensor with an infrared camera was installed in Tokyo-based residential nursing homes in April 2020. A pre/post intervention and observation study was conducted before and after the introduction of the device. Four care professionals worked each night in pairs (one person providing care, and the other observing and keeping minute-by-minute records of task and time allocated to each task. The tasks were divided into 33 items). The data were collected by two pairs at three different nights for pre-intervention and from two pairs at two nights for post-intervention. Ten care professionals participated in the study, and they were looking after 30 older adults (86.8 +/- 6.8 years old).
Results
The total time for executing various tasks marginally increased from 978 mins to 1033 mins. However, statistically significant changes were found mainly among items related to medical care and safety. While nurse call response time decreased significantly, the proportion of time allocated to personal care such as vital checks (from 1 to 2 percent) and mobility (from 4 to 9 percent) assistance doubled. Break time also increased significantly.
Conclusion
While the introduction of a safety monitoring system did not radically reduce the workload, it changed the patterns of caregiving during the night shift. Some behavioural changes were directly caused by functions of the system, while others were by-products. Staff’s break length also increased. The findings suggest that the introduction of Information and Communication Technology (ICT) in nursing homes has the potential to release time to care.

Abstract
Dynamic digital radiography (DDR) is a motion‐detecting technique with high temporal resolution. Flexible laryngoscopy is a common modality for the observation of the larynx; however, it generates aerosol. DDR is an easy and less risky screening test for the diagnosis of recurrent laryngeal nerve paralysis during the COVID‐19 pandemic.

Abstract
BACKGROUND The histological classifications of invasive lung adenocarcinoma subtypes are considered to predict patient prognosis after surgical treatment. The objectives of this study were to evaluate cytomorphological characteristics and proliferative activities among the histological predominant patterns by performing cytomorphometric and flow cytometric analyses using liquid-based cytology materials. METHODS Cytological samples fixed by liquid-based cytology preservatives from 53 surgically-resected lung adenocarcinoma specimens were obtained between August 2018 and November 2019. The Papanicolaou-stained and paired Ki-67-stained slides were analyzed for calculating nuclear morphology (nuclear area, nuclear perimeter and nuclear circularity) and Ki-67 labeling index using software. The cell proliferation index (CPIx) was calculated and cellular information including cell cycle stage of tumor cells was obtained by flow cytometry. RESULTS The 53 cases included papillary (n = 29), acinar (n = 8), lepidic (n = 5), and solid (n = 4) subtypes, and invasive mucinous adenocarcinoma (n = 7) were also included. In the lepidic pattern, nuclear area (79.6 ± 28.8 μm2 ) and perimeter (34.1 ± 6.1 μm) were relatively larger and longer than those of the other predominant patterns. The Ki-67 labeling index of the solid pattern (27.9 ± 12.5%) was highest compared with those of other predominant patterns. There were statistically significant differences in the lepidic versus solid patterns and the papillary versus solid patterns (p = .013 and p = .039, respectively). The calculated mean CPIx of the lepidic and the acinar patterns were approximately two-fold higher than those of the other predominant patterns. CONCLUSION By revealing the differences of cytomorphological characteristics, these methodologies might be used for diagnosing cytopathological materials using digital cytopathology.

Abstract
INTRODUCTION Molecular targeted therapies have been established for various diseases, including cancers, and there is an increasing need for molecular testing on cytology specimens. The aim of this study was to determine the optimal preservation methods of liquid-based cytology (LBC) materials for molecular testing. METHODS Cytological samples from 35 surgical resected non-small cell lung carcinoma specimens were obtained between June 2016 and June 2021. The samples were fixed in CytoRich™ red Preservative and stored at 4°C. One week later, three tubes were prepared from each specimen sample and divided into the following groups: the SurePath™ group (continued storage at 4°C), Frozen (Fr) group (stored at -80°C after centrifugation), and LBC-Cell Block (LBC-CB) group (generation of paraffin-embedded CB and storage at 4°C). Samples from 5 patients were used for the time course analysis, and we performed evaluations on these samples at 1, 3, 6, 12, 24, and 36 months. The concentrations and purities of extracted DNA and RNA were measured. The double-stranded DNA (dsDNA) and RNA concentrations were also measured by a fluorometer. The DNA and RNA integrities were quantified by the DNA and RNA integrity number. RESULTS Evaluation of samples was performed at baseline and the six timepoints. In the LBC-CB group, DNA and dsDNA concentrations were higher rather than those in the other groups. The RNA concentration of the LBC-CB group was relatively high compared with those of the other groups at the 36-month timepoint. The Fr group maintained higher DNA quality compared with the other groups over 3 years. The LBC-CB group maintained a higher RNA quality than the other groups until 24 months. CONCLUSION LBC-CB preparation is an effective method to maintain DNA/RNA quality and quantity in long-duration preservation for eventual molecular testing. Therefore, LBC-CB may have applications on preanalytical stage for molecular genomic testing such as next-generation sequencing.

Abstract
Perioperative complications have been reported to be associated with a lower incidence of cancer-free survival. Perioperative atrial fibrillation (POAF) is one of occasionally observed complications in patients with malignancies who undergo noncardiac surgeries. However, the long-term clinical impact of POAF on those with malignancies have remained unknown. This was a prospective, single-center, observational study. Patients who underwent noncardiac surgeries for definitive malignancies between 2014 and 2017 were included. The primary and secondary endpoints were 3-year recurrence of malignancies and cancer death, respectively. The present study included consecutive 752 patients (mean age, 68 ± 11 years; males, 62%), and POAF was observed in 77 patients. The follow-up duration was 1037 (interquartile range, 699-1408) days. The 3-year recurrence of malignancies was observed in 239 (32%) patients (POAF, 32 [42%]; non-POAF, 207 [31%]) and 3-year mortality was 130 patients (17%). Cardiac, noncardiac, and cancer deaths were observed in 4 (0.5%), 126 (17%), and 111 (15%) patients, respectively. Multivariate Cox regression analysis demonstrated that POAF was associated with 3-year recurrence of malignancies (hazard ratio [HR], 1.70; 95% confidence interval [CI], 1.15-2.52). Landmark analysis demonstrated that POAF tended to be correlated with the incidence of 3-year cancer death (HR, 1.79; 95% CI, 0.96-3.31). In conclusion, POAF is associated with the subsequent recurrence of malignancies. The association of arrhythmia with cancer death may be revealed under longer follow-up durations.Clinical Trial Registration: https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000018270 .

Abstract
OBJECTIVES Thymic epithelial tumors are the most common adult mediastinal tumors; however, their growth mechanism remains relatively unknown. Among the JAK/STAT pathway-related proteins, which control various intracellular events, STAT3 is deeply involved in cell proliferation. Constitutive activation of STAT3 and the resulting overexpression of cyclin D1 have been confirmed in various tumors, but have not been thoroughly investigated in thymic epithelial tumors. In this study, we immunohistochemically examined STAT3 activation, cyclin D1 expression, and JAK3 activation in thymic epithelial tumors and statistically analyzed their correlation with clinicopathological features. METHODS Formalin-fixed paraffin-embedded specimens of 94 thymic epithelial tumors surgically resected at Kyorin University Hospital between 2005 and 2018 were included in this study. pSTAT3, cyclin D1, and pJAK3 were immunohistochemically examined, and the correlation with histology, Masaoka stage, and survival time was statistically analyzed. RESULTS Cyclin D1 was found to be significantly overexpressed in the STAT3-activated group. This phenomenon was associated with histology and Masaoka stage. JAK3 was also activated in thymic epithelial tumors; however, JAK3 and STAT3 activation were not always correlated. Using survival time analysis, the STAT3-activated group, cyclin D1-expressed group, and JAK3-activated group had significantly lower progression-free survival times than those for both the non-activated and non-expressed groups. CONCLUSIONS STAT3 activation may promote cyclin D1 overexpression in thymic epithelial tumors, and intracellular signaling pathways other than JAK3 may be involved in STAT3 activation. STAT3 activation, cyclin D1 overexpression, and JAK3 activation are biomarker candidates that indicate clinically poor prognosis.

Abstract
Pulmonary artery aneurysms (PAAs) are rare, but clinically important because their rupture can cause sudden death. We present the first case of an asymptomatic patient with an unruptured PAA that was successfully diagnosed by dynamic digital chest radiography (DDCR) and was treated surgically. DDCR is a state-of-the-art temporally resolved radiographic technique that offers high-quality fluoroscopy-like images at a low radiation dose. Although noncontrast chest computed tomography (CT) revealed only a nonspecific nodule, DDCR delineated this lesion as a pulsatile nodule synchronized with cardiac pulsations, establishing the diagnosis of PAA. This diagnosis was confirmed by CT pulmonary angiography and surgery.

Abstract
Abstract
Background
Recent clinical trials have demonstrated a role for sodium glucose cotransporter 2 (SGLT2) inhibitors in improving cardiovascular outcomes in heart failure patients, but the underlying mechanisms remain unknown. We investigated the direct effects of canagliflozin, a non-selective SGLT1/SGLT2 inhibitor on myocardial redox signalling in humans.
Methods
Study 1 included 364 patients undergoing cardiac surgery. Human right atrial appendage biopsies, obtained during surgery, were used to quantify the sources of superoxide (O2.-) and the gene expression of inflammation, fibrosis and myocardial stretch markers. In Study 2, myocardial biopsies from 51 patients were used ex vivo to study the direct effects of canagliflozin on O2.- generation and understand its role in controlling the activity of NADPH-oxidases and uncoupled nitric oxide synthase (NOS). Finally, we used differentiated H9C2 and human primary cardiomyocytes (hCM) to further characterise the key regulatory mechanisms (Study 3).
Results
SGLT1 was abundantly expressed in the human myocardial biopsies and hCM whilst SGLT2 was barely detectable. SGLT1 expression levels were positively correlated with basal O2.- production and the expression of natriuretic peptides, proinflammatory cytokines and pro-fibrotic markers in human myocardial biopsies from study 1. Incubation of human myocardium with canagliflozin significantly reduced basal and NADPH-oxidase-derived O2.- via AMP kinase (AMPK)-mediated suppression of GTP-activation and consequent reduction of membrane translocation of Rac1, an NADPH-oxidase subunit. This resulted in reduced oxidation and increased bioavailability of tetrahydrobiopterin, the nitric oxide synthase (NOS) co-factor essential for enzymatic coupling, leading to improved NOS coupling. These findings were replicated in hCM, where canagliflozin was shown to regulate AMP/ATP ratio, which could be upstream of AMPK activation. The effects of canagliflozin were significantly attenuated by knocking-down SGLT1 in hCM. Transcriptional profiling of hCM treated with canagliflozin revealed that canagliflozin had striking effects on myocardial redox signalling, causing suppression of apoptotic and inflammatory pathways in the human heart.
Conclusions
We demonstrate for the first time in humans that canagliflozin suppresses myocardial NADPH-oxidase activity and improves NOS coupling through an SGLT1/AMPK/Rac1-mediated pathway, leading to global anti-inflammatory and anti-apoptotic effects in the human myocardium. These findings provide a mechanistic basis for the beneficial effects of SGLT1/2 inhibitors in patients with heart failure.

Abstract
Study objectives Niemann-Pick type C (NPC) is an autosomal recessive and congenital neurological disorder characterized by the accumulation of cholesterol and glycosphingolipids. Symptoms include hepatosplenomegaly, vertical supranuclear saccadic palsy, ataxia, dystonia, and dementia. Some cases frequently display narcolepsy-like symptoms, including cataplexy which was reported in 26% of all NPC patients and was more often recorded among late-infantile onset (50%) and juvenile onset (38%) patients. In this current study, we examined CSF orexin levels in the 10 patients of NPC with and without cataplexy, which supports previous findings. Methods Ten patients with NPC were included in the study (5 males and 5 females). NPC diagnosis was biochemically confirmed in all 10 patients, from which 8 patients with NPC1 gene were identified. We compared CSF orexin levels among NPC, narcoleptic and idiopathic hypersomnia patients. Results Six NPC patients with cataplexy had low or intermediate orexin levels. In 4 cases without cataplexy, their orexin levels were normal. In 5 cases with Miglustat treatment, their symptoms stabilized or improved. For cases without Miglustat treatment, their conditions worsened generally. The CSF orexin levels of NPC patients were significantly higher than those of patients with narcolepsy-cataplexy and lower than those of patients with idiopathic hypersomnia, which was considered as the control group with normal CSF orexin levels. Discussion Our study indicates that orexin level measurements can be an early alert of potential NPC. Low or intermediate orexin levels could further decrease due to reduction in the neuronal function in the orexin system, accelerating the patients’ NPC pathophysiology. However with Miglustat treatment, the orexin levels stabilized or improved, along with other general symptoms. Although the circuitry is unclear, this supports that orexin system is indeed involved in narcolepsy-cataplexy in NPC patients. Conclusion The NPC patients with cataplexy had low or intermediate orexin levels. In the cases without cataplexy, their orexin levels were normal. Our study suggests that orexin measurements can serve as an early alert for potential NPC; furthermore, they could be a marker of therapy monitoring during a treatment.

Abstract
Abstract
Introduction
Recently, attention has been paid to the relationship between developmental disorders such as attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), and sleep disorders. We meet many developmental disorder patients who complaint hypersomnolence. Among these patients, cases with coexistence of central hypersomnia and developmental disorders, or developmental disorder alone were increased. Therefore, we first investigated patients with the complaint of hypersomnolence, who were also suspected developmental disorders. Furthermore, we have been measuring CSF orexin in 17 cases suspected of both disorders to investigate orexin levels of these patients.
Methods
86patients who complained of EDS with suspicion of developmental disorders had been examined. In order to diagnose hypersomnolence disorders, PSG and MSLT were performed. Psychological examinations were performed for diagnosing developmental disorders.We have been measuring for CSF orexin in 17 cases suspected both hypersomnolence and developmental disorders. We examined the onset of hypersomnolence and the clinical history of these ADHD or ASD cases for more details.
Results
In 86 examined cases, developmental disorders coexisted in 30 cases. Among 30 cases, ADHD were 18, ASD were 6 and both diagnosed were 6 cases. Among them, 20 cases diagnosed as having coexistence of hypersomnia (8: narcolepsy, 12: IHS) and developmental disorders (ADHD:12, ASD:4, ADHD/ASD:4). In 17 cases with orexin measurements, 10 cases coexisted ADHD and 4 cases coexisted ASD. Two cases diagnosed as both ADHD and ASD. In 10 ADHD cases, 3 cases had low orexin levels, and 7 cases had normal orexin levels. Other 7 ASD cases had normal orexin levels.
Conclusion
ADHD has a higher rate of central hypersomnia (12/18) compared with ASD and the rate of narcolepsy was also high (5/12). While patients in ASD was diagnosed as IHS (3/6), narcolepsy cases were not observed. It became clear that the majority of patients had developmental disorder or had a tendency for developmental disorder before the onset of hypersomnolence.Although it is possible that ADHD/ASD symptoms may be exacerbated by orexin dysfunctions, ADHD/ASD may not newly occur. There were cases with low orexin levels, but it seems that narcolepsy happened to coexist with developmental disorders.

Abstract
Cortical activity during jaw movement has been analyzed using various non-invasive brain imaging methods, but the contribution of orofacial sensory input to voluntary jaw movements remains unclear. In this study, we used functional magnetic resonance imaging (fMRI) to observe brain activities during a simple teeth tapping task in adult dentulous (AD), older dentulous (OD), and older edentulous subjects who wore dentures (OEd) or did not wear dentures (OE) to analyze their functional network connections. (1) To assess the effect of age on natural activation patterns during teeth tapping, a comparison of groups with natural dentition—AD and OD—was undertaken. A general linear model analysis indicated that the major activated site in the AD group was the primary sensory cortex (SI) and motor cortex (MI) (p < 0.05, family wise error corrected). In the OD group, teeth tapping induced brain activity at various foci (p < 0.05, family wise error corrected), including the SI, MI, insula cortex, supplementary motor cortex (SMC)/premotor cortex (PMA), cerebellum, thalamus, and basal ganglia in each group. (2) Group comparisons between the OD and OEd subjects showed decreased activity in the SI, MI, Brodmann’s area 6 (BA6), thalamus (ventral posteromedial nucleus, VPM), basal ganglia, and insular cortex (p ¡ 0.005, uncorrected). This suggested that the decreased S1/M1 activity in the OEd group was related to missing teeth, which led to reduced periodontal afferents. (3) A conjunction analysis in the OD and OEd/OE groups revealed that commonly activated areas were the MI, SI, cerebellum, BA6, thalamus (VPM), and basal ganglia (putamen; p < 0.05, FWE corrected). These areas have been associated with voluntary movements. (4) Psychophysiological interaction analysis (OEd vs OE) showed that subcortical and cortical structures, such as the MI, SI, DLPFC, SMC/PMA, insula cortex, basal ganglia, and cerebellum, likely function as hubs and form an integrated network that participates in the control of teeth tapping. These results suggest that oral sensory inputs are involved in the control of teeth tapping through feedforward control of intended movements, as well as feedback control of ongoing movements.

Abstract
BACKGROUND Liquid-based cytology (LBC) allows immunohistochemistry (IHC), fluorescence in situ hybridization, and molecular testing to be performed in fixed cell materials. We examined the feasibility of subtyping and EGFR mutation testing of bronchoscopic samples from patients with lung cancer using cell blocks (CB) based on LBC fixation (LBC-CB). METHODS We included 35 consecutive patients with peripheral lung nodules who underwent endobronchial ultrasonography with a guide sheath in our hospital. Thirty of these patients were diagnosed with lung cancer by obtaining cytological samples. Cytological subtyping was performed with IHC using LBC-CB, and the Cobas EGFR Mutation Test ver. 2 was performed using extracted genomic DNA from the LBC-CB, formalin-fixed paraffin-embedded (FFPE) tissue, and matched plasma. RESULTS Of the 30 cases, 25 were classified cytomorphologically as adenocarcinoma (ADC, n = 17) and squamous-cell carcinoma (SQCC, n = 8). The remaining five cases were classified by IHC as favor ADC (n = 3) and favor SQCC (n = 2) according to the WHO criteria. In the final ADC group (n = 20), EGFR mutations on the LBC-CB were identified in eight cases (40%; 1 exon 19 deletion, 6 L858R, and 1 L861Q). Mutations in FFPE samples were identified in seven cases (35%) at the same site in each case. Plasma EGFR mutations were identified in four cases (20%) at the same site. The CB detection rate was higher than for FFPE and plasma. CONCLUSION LBC-CB is suitable for subtyping and EGFR mutation testing in lung cancers.

Abstract
We report a rare case where the inferior vena cava connected to the azygos vein, a diagnosis triggered by observation of an enlarged azygos vein traversing an azygos fissure. A 16-year-old male patient presented with an abnormal shadow on chest X-ray. Chest computed tomography showed an enlarged azygos vein connecting to the inferior vena cava, with no other connection to the atrium. There were no associated malformations. The patient remains alive and has been asymptomatic for the past two years. If the flow through the connection was to be interrupted during the course of thoracic or abdominal surgery, this would invariably prove to be fatal. In addition, this abnormality prevents direct access to the atrium on attempting interventional radiology via the inferior vena cava, for example, during ablation. When an azygos lobe is identified on a chest X-ray, a prominent solid structure traversing it may represent an engorged azygos vein with an anomalous course.

Abstract
BACKGROUND Various complications can cause hypoxemia after pulmonary resection for lung cancer, but intracardiac shunt that becomes symptomatic and causes severe hypoxemia postoperatively is very rare. We report a case that presented platypnea-orthodeoxia syndrome (POS) due to right-to-left shunt via patent foramen ovale (PFO). CASE A 71-year-old man with a lung cancer in the left upper lobe was referred to our hospital. Left upper lobectomy was performed. Dyspnea developed postoperatively, which was worsened by sitting or standing and relieved in a recumbent position. Contrast transesophageal echocardiogram (TEE) and right intracardiac catheterization revealed a right-to-left shunt via PFO. Open-heart closure of PFO was performed and the patient was free from POS. CONCLUSIONS Postoperative intracardiac shunt via PFO can cause severe hypoxemia after lung resection. POS suggests the possibility of intracardiac shunt and careful observation is needed.

Background
Sodium glucose cotransporter 2 (SGLT2) inhibitors are antidiabetic drugs that control plasma glucose levels by inhibiting reabsorption of glucose in kidney. Recent clinical trials have suggested a class effect of SGLT2 inhibitors in preventing hospitalization due to heart failure. However, the underlying mechanism has not been fully elucidated.
Purpose
We investigated the direct effect of the SGLT2 inhibitor, Canagliflozin (Cana), on myocardial redox state in humans.
Methods
The study included 48 patients undergoing cardiac surgery. Fresh myocardial tissues were incubated ex vivo with or without Cana and then used for superoxide quantification and Western immunoblotting. NADPH-oxidases activity was evaluated with NADPH 100μM stimulation, while nitric oxide synthase (NOS) coupling was assessed by using N(ω)-nitro-L-arginine methyl ester (L-NAME, a NOS inhibitor). A human cardiomyocyte (HCM) cell line was also used for in vitro validation of the effects of Cana on myocardium.
Results
Ex vivo incubation of myocardium with Cana significantly reduced baseline (A) and NADPH-oxidase-derived O2·− (B) and improved NOS coupling reflected by positive L-NAME delta O2·− values (C). Regulation of NADPH-oxidases activity by Cana was found to result from reduced GTP-activation (D) and consequent membrane translocation (E) of Rac1, a key subunit of NADPH-oxidases. Cana also reduced tetrahydrobiopterin (BH4) oxidation, increasing its bioavailability (F), which is a key mechanism to improve NOS coupling. Incubation with Cana enhanced phosphorylation of AMPK, and the downstream signalling, ACC (not shown). Additional Compound C, which is inhibitor of AMPK, significantly reversed these effects of Cana (A, B, C, D, E, F). These findings were replicated in HCM (not shown). In line with these, Cana increased the ADP/ATP ratio of cytoplasm in HCM, which could provide an upstream mechanism for AMPK activation.
Conclusions
We demonstrate for the first time in humans, that Cana suppresses myocardial NADPH-oxidases activity and improves NOS coupling through an AMPK-mediated pathway. This could be an underlying mechanism for the cardioprotective effects of SGLT2 inhibitors.

Abstract
Abstract
Background
Impact of hyponatremia improvement on prognosis in patients with acute decompensated heart failure (ADHF) remains unclear.
Methods
Patients hospitalized for ADHF at 19 hospitals in Japan were enrolled between October 2014 and March 2016. Hyponatremia was defined as serum sodium concentration less than 135 mmol/l. Primary endpoint was composite of all-cause death and heart failure rehospitalization one year after discharge.
Results
Among 3805 patients enrolled, 486 patients with hyponatremia at admission showed higher in-hospital mortality (13.3% vs. 5.4%, p<0.001). Of 486 hyponatremic patients, 396 patients were discharged alive. One hundred forty-three patients showed persistent hyponatremia at discharge (group P), whereas 253 patients showed improvement of hyponatremia (group I). Baseline characteristics are shown in the table. Patients in group I showed higher sodium concentration at admission (132±3 mmol/l vs. 130±4 mmol/l, p<0.001) and more increase in serum sodium concentration at discharge (7±4 mmol/l vs. 1±5 mmol/l, p<0.001). One-year survival rate free from primary endpoint was not different between the groups (56.4% in group P vs. 58.5% in group I, p=0.79). After adjusting for confounders, improvement of hyponatremia was not associated with better prognosis (hazard ratio 1.00; 95% confidence interval 0.70–1.45, p=0.99). Hyponatremia improvement showed significant interaction with left ventricular ejection fraction (LVEF) less than 40% (p=0.01). In patients with LVEF<40%, improvement of hyponatremia was associated with better prognosis (hazard ratio 0.48, 95% confidence interval 0.28–0.85, p=0.01) whereas not in patients LVEF≥40%.
Patient characteristics Group P (n=143) Group I (n=253) p value Age (years) 81 (72–86) 81 (72–87) 0.73 Female 71 (49.7) 110 (43.5) 0.24 Ischemic etiology 42 (29.4) 81 (32.0) 0.58 Prior hospitalization 62 (43.7) 98 (39.5) 0.42 SBP at admission (mmHg) 140±36 144±38 0.40 HR at admission (bpm) 92±23 95±29 0.27 Atrial Fibrillation 47 (32.9) 103 (40.7) 0.12 NYHA class IV 60 (42.2) 138 (54.8) 0.02 Intravenous inotropic use 35 (24.5) 59 (23.3) 0.80 LVEF <40% 54 (37.8) 95 (37.6) 0.97 Values are median (interquartile range), mean ± standard deviation or number (%).
Conclusion
Improvement of hyponatremia at discharge was not associated with better prognosis in patients hospitalized for ADHF.

Abstract
Abstract
Background
Cardiac hypertrophy is a compensatory response to pressure overload that leads to heart failure. Recent studies have shown that Rho signaling has crucial regulatory roles in actin cytoskeleton rearrangement during cardiac hypertrophic responses. Rho is rapidly activated in response to pressure overload, but the mechanisms by which Rho and its downstream proteins control actin dynamics during hypertrophic responses remain unclear.
Objective
To identify the essential roles of mDia1 (Rho-effector molecule) in pressure overload-induced ventricular hypertrophy.
Methods and results
Male wild-type (WT) and mDia1-knockout (mDia1KO) mice (10–12 weeks old) were subjected to transverse aortic constriction (TAC) or a sham operation. The heart weight/tibia length ratio, cardiomyocyte cross-sectional area, left ventricular wall thickness, and expression of hypertrophy-specific genes were significantly decreased in mDia1KO mice 3 weeks after TAC, and the mortality rate was higher at 12 weeks. Echocardiography and the pressure-volume loop indicated that mDia1 deletion increased the severity of heart failure 8 weeks after TAC. Microarray gene expression profiling showed that the induction of immediate early genes due to the TAC operation was significantly lower in mDia1KO mice than WT mice, as was the activation of extracellular signal-regulated kinase (ERK) and focal adhesion kinase (FAK). We examined the role of mDia1 in neonatal rat ventricular cardiomyocytes (NRVMs) exposed to mechanical stress. The siRNA-mediated silencing of mDia1 attenuated stretch-induced ERK and FAK phosphorylation, and gene expression of c-fos. Importantly, loss of mDia1 suppressed an increase in the F/G-actin ratio in response to pressure overload in the mice. In addition, increases in nuclear myocardin-related transcription factors (MRTFs) and serum response factor (SRF) were perturbed in response to pressure overload in mDia1KO mice and to mechanical stretch in mDia1 depleted NRVMs.
Conclusions
Rho-mDia1, through actin dynamics, plays critical roles in pressure overload-induced hypertrophy by regulating ERK and FAK phosphorylation and the transcriptional activity of MRTF-SRF.

Abstract
Abstract
Background
Cardiac sarcoidosis is a cause of epicarditis and sustained life-threatening ventricular arrhythmias. These arrhythmias occasionally arise from epicardial. Positron emission tomogramphy-comututed tomography (PET-CT) is useful for diagnosis with sarcoidosis. However, the usefulness for prediction of ventricular arrhythmias in patients with cardiac sarcoidosis is unknown.
Objective
We hypothesized that the evaluation of pericardial fat inflammation could identify high-risk sarcoidosis patients for ventricular arrhythmias.
Methods
We enrolled 20 consecutive patients with cardiac sarcoidosis performed PET-CT between August 2016 and December 2018. In each case, we measured the maximum standardized uptake value (SUVmax) of pericardial fat around the left atrium, both ventricules, atrioventricular groove, and left main coronary.
Results
Seven patients experienced ventricular tachycardia (VT) or ventricular fibrillation (VF). VT/VF patients had significantly more complete right bundle branch block (P=0.035), larger left atrial dimension (P=0.021), larger left ventricular end-diastolic dimension (P=0.005), lower ejection fraction (P=0.007), and higher E/e' (P=0.004). SUVmax of pericardial fat in the roof of left atrium (LA) and left ventricular (LV) with VT/VF patients were significantly higher than non-VT/VF patients (LA: 1.63 vs 1.32, P=0.0311; LV: 1.84 vs 1.26, P=0.045). The cut-off values of SUVmax derived from the ROC curve in the roof of LA and LV are 1.47 and 1.59 respectively. The Kaplan Meire estimator showed that high SUVmax patients in the roof of LA had significantly more detection of NSVT.
Conclusions
Our results suggest the relationship between SUVmax and VT/VF occurrence in patients with cardiac sarcoidosis. The evaluateon of SUVmax may be useful for VT/VF risk stratification.

Abstract
Background Perioperative atrial fibrillation (POAF) is one of the common arrhythmias in the setting of non-cardiac surgeries for malignancy. As POAF may cause subsequent adverse events, it is important to confirm its characteristics and risk factors. Materials and methods The prospective cohort study of surveillance for perioperative atrial fibrillation recurrence (PREDICT AF RECURRENCE) is an ongoing prospective, single-center, observational study that aims to illustrate the clinical impact of POAF in major non-cardiac surgery for malignancy. Patients who planned to undergo non-cardiac surgery for definitive/suspected malignancy were registered. Those with a history of AF and atrial flutter were excluded. Any 30-day complications included acute myocardial infarction, congestive heart failure, bleeding, thrombosis, any infection, and acute kidney injury. The primary endpoint was an incidence of POAF. Results The present study included 799 patients (age, 68 ± 11; male, 62%). Of these, 80 patients (10.0%) developed POAF. Notably, 66 patients (83%) had no symptoms. Any 30-day complications occurred in 180 patients (23%) (with POAF: 34 (43%); without POAF: 146 (20%); p < 0.001). POAF in 17 patients (50%) was preceded by the development of complications. No patient developed cardiogenic shock and/or acute heart failure. The association between 30-day complications and POAF development were analyzed using the multivariate adjusted model (odds ratio: 2.84; 95% confidence interval: 1.74–4.62; p < 0.001). Conclusion Ten percent of patients who underwent non-cardiac surgery for malignancy developed POAF, which was strongly associated with perioperative complications. As a majority were asymptomatic, careful observation using electrocardiography monitoring is important to avoid oversights. Clinical trial registration UMIN ID: UMIN000016146

Abstract
INTRODUCTION Many reports show that denture adhesives improve the retention and stability of dentures. However, few randomized controlled trials have examined the effects of denture adhesives. OBJECTIVE This 10-center randomized controlled trial with parallel groups involving 200 edentulous patients wearing complete dentures aimed to evaluate the effects of short-term use of cream and powder denture adhesives. METHODS Patients were allocated into 2 cream- and powder-type adhesive groups and 1 control group. Intervention groups were treated with the 2 adhesives (1 each), and the control group received saline solution. Adhesive or control was applied to the denture-mucosal surface for 4 d, and data at baseline and after day 4 of intervention (i.e., 8 meals) were obtained. Patient satisfaction was evaluated with a 100-mm visual analog scale. Oral health-related quality of life was measured with the Japanese version of the Oral Health Impact Profile for Edentulous Patients. Perceived chewing ability was evaluated by a questionnaire regarding ease of chewing and swallowing food. Between-group comparisons were performed with Kruskal-Wallis tests with the Mann-Whitney U test adjusted by Bonferroni correction. Within-group comparisons of pre- and postintervention measurements were performed with the Wilcoxon signed-rank test. Intention-to-treat analysis was also performed. RESULTS Between-group comparisons showed no significant differences for general satisfaction or Oral Health Impact Profile for Edentulous Patients. However, significant differences in satisfaction with various denture functions with cream- and powder-type adhesives were seen in pre- and postintervention comparisons (P < 0.05). Significant differences were also observed for perceived chewing ability of hard foods (P < 0.05). CONCLUSION These results suggest that although denture adhesives do not invariably improve denture function, they do affect subjective evaluations and possibly chewing of hard foods. Therefore, the effects of denture adhesive use are insufficient to resolve any fundamental dissatisfaction with dentures ( ClinicalTrials.gov NCT01712802 ). KNOWLEDGE TRANSFER STATEMENT The results of this study suggest that denture adhesives should be applied under certain conditions; however, an appropriate diagnosis is important before application. These practice-based data provide information to establish evidence-based guidelines for applying denture adhesives.

Abstract
OBJECTIVES Outcomes and prognostic factors remain obscure in patients with colorectal cancer after pulmonary metastasectomy who had previously received a curative hepatic metastasectomy. METHODS We collected data of 757 patients with pulmonary metastasis from colorectal cancer who underwent curative metastasectomy between 2004 and 2008 from 46 Japanese institutions, from which we extracted data on patients who previously received curative hepatic metastasectomy. Disease-free survival, overall survival, and prognostic factors were analyzed. RESULTS The subjects of this study were 160 patients, of whom 44% had primary rectal tumor, 73% had a single pulmonary metastasis, 11% had a bilateral pulmonary metastasis, and 39% had high (>5 ng/mL) serum carcinoembryonic antigen. Patients' median age was 66 years, and 58% were male. The median follow-up was 64 months. Five-year overall survival and disease-free survival were 65.2% (95% confidence interval, 56.8-72.5) and 33.5% (95% confidence interval, 26.1-41.0), respectively. In multivariable analyses, high prethoracotomy carcinoembryonic antigen level was an independent prognostic factor for overall survival (hazard ratio, 2.01; 95% confidence interval, 1.16-3.47) and disease-free survival (hazard ratio, 2.10; 95% confidence interval, 1.41-3.12). Five-year overall survival and disease-free survival of patients with normal prethoracotomy carcinoembryonic antigen level were 76.4% (95% confidence interval, 66.1-83.9) and 40.7% (95% confidence interval, 30.5-50.5), respectively. CONCLUSIONS After pulmonary metastasectomy, approximately two thirds of patients with colorectal cancer with a history of curative hepatic metastasectomy survived for 5 years-half of them disease-free. Our results indicate that patients with colorectal cancer with pulmonary metastasis and a history of curative hepatic metastasectomy may benefit from sequential pulmonary metastasectomy, especially if prethoracotomy serum carcinoembryonic antigen levels are within normal range.

Abstract
Postpartum hemorrhage (PPH) remains a leading cause of maternal death worldwide, and it is important to understand the relative contributions of different risk factors. We assessed the incidence of these among cases of transvaginal delivery. Between June 2013 and July 2016, a prospective cohort study was conducted at a tertiary perinatal medical facility in Japan. Women were administered a questionnaire to ascertain risk factors for PPH, defined as a blood loss of 1,000 ml or more assessed using a calibrated under-buttocks drape and collection vessel at childbirth. We analyzed 1,068 transvaginal deliveries of singleton pregnancies. The incidence of PPH was 8.7%, and of severe PPH (1,500 ml blood loss or more) was 2.1%. Risk factors for postpartum hemorrhage among the deliveries were: fetal macrosomia (over 4000 g); pregnancy-induced hypertension; pregnancy generated by assisted reproductive technology; severe vaginal or perineal lacerations; and weight gain over 15 kg during pregnancy. Such high weight gain significantly increased the incidence of PPH compared with women showing less than 10 kg weight gain during pregnancy. Monitoring these identified risk factors could enable extra vigilance during labor, and preparedness for managing PPH in all women giving birth.

Abstract
BACKGROUND Pulmonary metastases from colorectal cancer are resected due to the favourable 5-year overall survival rates of 30-60% reported in many studies. However, the efficacy of subsequent adjuvant chemotherapy remains unclear. PATIENT AND METHODS We retrospectively collected clinical data of 1237 patients who underwent surgical resection of pulmonary metastasis from colorectal cancer at 46 Japanese institutions between 2004 and 2008. Patients with non-curative resection, pre-operative chemotherapy, extra-thoracic metastasis, complications after surgery, and inadequate data were excluded. Then, a 1:1 propensity score nearest-neighbour matching between patients with and without adjuvant chemotherapy was performed, considering relevant co-variables, and survival of patients between groups was compared. RESULTS Data of 524 patients (surgery alone, 269 patients; surgery with adjuvant chemotherapy, 255 patients) were used for matching. From each group, 192 patients with similar background characteristics between groups were selected. Adjuvant chemotherapies included fluoropyrimidine alone (71%), an oxaliplatin-containing regimen (23%), or an irinotecan-containing regimen (6%). In the surgery alone and adjuvant chemotherapy groups, 5-year overall survival rates were 68% and 69%, and 5-year disease-free survival rates were 40% and 34%, respectively. There were no significant differences between the two groups in terms of overall survival (hazard ratio [HR]: 1.00, 95% confidence interval [CI]: 0.69-1.45, P = 1.00) and disease-free survival (HR: 1.07, 95% CI: 0.82-1.39, P = 0.62). CONCLUSIONS Adjuvant chemotherapy after curative resection of lung-limited metastasis from colorectal cancer did not show a survival benefit in the propensity score-matched analysis and should not be recommended without further clinical trials.

Abstract
Severe combined immunodeficiency disease (SCID) mice with human lepidic adenocarcinoma were established by the intrabronchial implantation of fresh surgically resected specimens. Human pulmonary adenocarcinoma tissue from 16 different cases was transplanted into SCID mice, and SCID mouse tumors were established from four of these cases (25%). Among the four tumors, the tumor cells of two SCID mice showed replacement lepidic growth of mouse alveolar structures accompanied by multiple intrapulmonary lesions. Human lung carcinoma cell lines showing lepidic growth are rare and the xenograft models using the SCID mouse model developed in the current study will be useful for analyzing the growth and/or progression patterns and clinical behavior of lepidic adenocarcinoma, the major histological subtype of human carcinoma of the lung.

Abstract
Circulating microRNAs (miRNAs) are promising markers for cancer diagnosis and prognosis. Numerous studies evaluating miRNAs as markers for non-small cell lung cancer (NSCLC) have been conducted in recent years; however, the majority of candidate markers proposed via individual studies were inconsistent and no marker miRNAs for the diagnosis of early stage NSCLC have been established. In the present study, miR-145, miR-20a, miR-21 and miR-223, which were previously reported as candidate diagnostic markers of NSCLC, were re-evaluated. The serum levels of these miRNAs were quantified in 56 patients with stage I-IV NSCLC using the TaqMan microRNA assays and separately compared the levels at each stage with those in 26 control patients. The level of miR-145 was significantly reduced in patients with NSCLC, regardless of clinical stage, and its level increased following tumor resection in patients with stage I-II disease. These results indicate that miR-145 is relevant as a diagnostic marker for stages I-IV NSCLC. Additionally, the levels of miR-20a and miR-21 demonstrated notable differences among patients at different clinical stages. These miRNAs distinguished patients in a number of, but not all, stages of NSCLC from cancer-free control patients. These results indicated that it is essential to analyze miRNA levels at each stage separately in order to evaluate marker miRNAs for NSCLC diagnosis.

Abstract
Primary peritoneal carcinosarcoma is extremely rare and only few cases have been reported in the literature to date. We herein present a case of carcinosarcoma of the Douglas pouch in a 73-year-old Japanese woman. The patient complained of fever and lower abdominal pain, and a large pelvic mass (>10 cm in diameter) was detected, with rectal invasion. Laparotomy was performed and revealed a left ovarian abscess and a Douglas pouch mass; however, there was no obvious tumor involvement of the bilateral ovaries or uterus. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and tumor debulking, with a reduction rate of ~30%. Sigmoid colostomy was also performed due to the deep and wide rectal invasion. Histologically, the tumor was composed of a mixture of ovarian high-grade serous carcinoma and spindle-cell sarcoma mimicking leiomyosarcoma. Immunohistochemically, the serous carcinoma component was positive for cytokeratin (CK)7, Wilms' tumor-1 and p53 (null type), while CDX-2 and CK20 were negative. The spindle-cell sarcoma component was positive for vimentin and α-smooth muscle actin. The present case was diagnosed as carcinosarcoma of the homologous type derived from the peritoneum in the Douglas pouch. The patient received several courses of combination chemotherapy with paclitaxel, carboplatin and bevacizumab, and achieved complete remission. The principal treatment for such cases is surgery, and several chemotherapeutic regimens, including paclitaxel and carboplatin, or cisplatin and ifosfamide, have been reported. The accumulation of more clinical cases is crucial for understanding the clinicopathological characteristics of these rare tumors and establishing effective therapeutic strategies.

Abstract
OBJECTIVES Using data obtained from a Japanese nationwide annual database with web-based data entry, we developed a risk model of mortality and morbidity after lung cancer surgery. METHODS The characteristics and operative and postoperative data from 80 095 patients who underwent lung cancer surgery were entered into the annual National Clinical Database of Japan data sets for 2014 and 2015. After excluding 1501 patients, the development data set for risk models included 38 277 patients entering in 2014 and the validation data set included 40 317 patients entering in 2015. Receiver–operating characteristic curves were generated for the outcomes of mortality and composite mortality/major morbidity. The concordance index was used to assess the discriminatory ability and validity of the model. RESULTS The 30-day mortality and overall mortality rates, including in-hospital deaths, were 0.4% and 0.8%, respectively, in 2014, and 0.4% and 0.8%, respectively, in 2015. The rate of major morbidity was 5.6% in 2014 and 5.6% in 2015. Several risk factors were significantly associated with mortality, namely, male sex, performance status, comorbidities of interstitial pneumonia and liver cirrhosis, haemodialysis and the surgical procedure pneumonectomy. The concordance index for mortality and composite mortality/major morbidity was 0.854 (P < 0.001) and 0.718 (P < 0.001), respectively, for the development data set and 0.849 (P < 0.001) and 0.723 (P < 0.001), respectively, for the validation data set. CONCLUSIONS This model was satisfactory for predicting surgical outcomes after pulmonary resection for lung cancer in Japan and will aid preoperative assessment and improve clinical outcomes for lung cancer surgery.

Abstract
Background A previous retrospective cohort study established the relationship between perioperative atrial fibrillation (POAF) and subsequent mortality and stroke. However, the details regarding the cause of death and etiology of stroke remain unclear. Methods The prospective cohort study of surveillance for perioperative atrial fibrillation recurrence in major non-cardiac surgery for malignancy (PREDICT AF RECURRENCE) registry is an ongoing prospective cohort study to elucidate the long-term recurrence rate and the clinical impact of new-onset POAF in the setting of head and neck, non-cardiac thoracic, and abdominal surgery for malignancy. In this study, cardiologists collaborate with a surgical team during the perioperative period, carefully observe the electrocardiogram (ECG) monitor, and treat arrhythmia as required. Furthermore, patients who develop new-onset POAF are followed up using a long-term Holter ECG monitor, SPIDER FLASH-t AFib®, to assess POAF recurrence. Discussion Even if patients with malignancy survive by overcoming the disease, they may die from any preventable cardiovascular diseases. In particular, those with POAF may develop cardiogenic stroke in the future. Because details of the natural history of patients with POAF remain unclear, investigating the need to continue anticoagulation therapy for such patients is necessary. This study will provide essential information on the recurrence rate of POAF and new insights into the prediction and treatment of POAF.
