Abstract
Hypoxia leads to post-treatment metastasis and recurrences of cancer via the epithelial-mesenchymal transition (EMT). Radiotherapy itself may also contribute to the acquisition of EMT phenotypes. Despite extensive studies on the EMT driven by either hypoxia or radiation stimuli, the molecular mechanisms characterizing these EMT events remain unclear. Thus, we aimed to evaluate the differences in the molecular pathways between hypoxia-induced EMT (Hypo-EMT) and radiation-induced EMT (R-EMT). Further, we investigated the therapeutic effects of HIF-1α inhibitor (LW6) on Hypo-EMT and R-EMT cells. A549 cells, lung adenocarcinoma cell line, acquired enhanced wound-healing activity under both hypoxia and irradiation. Localization of E-cadherin was altered from the cell membrane to the cytoplasm in both hypoxia and irradiated conditions. Of note, the expression levels of vimentin, one of the major EMT markers, was enhanced in irradiated cells, while it decreased under hypoxia condition. Importantly, LW6 significantly blocked EMT-related malignant phenotypes in both Hypo-EMT cells and R-EMT cells with concomitant re-location of E-cadherin onto the cell membrane. Moreover, LW6 deflected stress responsive signalling, JNK, activated sustainably under hypoxic condition, and the blockage of JNK impaired EMT phenotypes. Together, this work demonstrated the molecular events underlying Hypo-EMT and R-EMT, and highlighted HIF-1α as a therapeutic target not only in Hypo- EMT, but also in R-EMT.

Abstract
Abstract
Introduction
Patients with heart failure are reported to have activated platelets leading to thrombotic events. Consequently, immature giant platelets are produced, and platelet distribution width (PDW) and mean platelet volume (MPV) increase. These platelet indices are easily, reasonably, and safely available by routine blood test and recently have been proposed as potential markers of cardiac events. However, little is known about the usefulness of platelet indices in patients with congenital heart disease (CHD).
Purpose
To test whether the hypothesis that PDW and MPV correlate to the severity of heart failure and have prognostic value in both future heart failure-related admission and thrombosis formation in patients with CHD.
Methods
We performed a retrospective, single-centre study that included 400 patients with CHD (median age, 34 years [range: 12–76]; 49% males; 35% single ventricular morphology), who were admitted in our institute between April 2014 and June 2017. We reviewed patients' medical records to assess their clinical information including medical history, blood sample data, and echocardiologic parameters. At first, we assessed the correlation between platelet indices and patients' clinical parameters. Next, we compared platelet indices before and after treatment for heart failure. Finally, using logistic regression and Kaplan-Meier analyses, we assessed prognostic factors of future heart failure-related admission and thrombosis formation.
Results
In multivariate analysis, a significant correlation was found between PDW and logBNP (brain natriuretic peptide) (p<0.001), haemoglobin (p=0.01), D-dimer (p=0.019), Fontan operation (p<0.001) and male sex (p<0.001); as well as between MPV and logBNP (p<0.001), D-dimer (p<0.001) and Fontan operation (p=0.002). Throughout treatment of heart failure, significant reduction was found both in PDW (average value before treatment = 14.2, after treatment = 13.2, p=0.002) and MPV (before = 11.2, after = 10.8, p=0.004). In multivariate logistic regression analysis, predictors of future heart failure-related admissions were PDW (hazard ratio [HR]: 1.365; 95% confidence interval [CI]: 1.005–1.768), MPV (HR: 1.472; 95% CI: 1.055–2.052), age (HR: 1.063; 95% CI: 1.010–1.119), and SpO2 under 85% (HR: 5.089; 95% CI: 1.350–19.18). Using the same analysis, predictors of thrombotic formation were PDW (HR: 1.998; 95% CI: 1.461–2.630), MPV (HR: 1.792; 95% CI: 1.155–2.781), logBNP (HR: 1.196, 95% CI: 1.085–1.320), D-dimer (HR: 1.024; 95% CI: 1.007–1.042) and male sex (HR: 3.071; 95% CI: 1.079–8.737). In addition, during median follow-up of 28 months, the Kaplan-Meier analysis showed an improvement in both heart failure and thrombosis-free survival in the low PDW, as well as the low MPV group.
Conclusion
Platelet volume indices correlate to severity of heart failure and have prognostic value for both cardiac and thrombotic events in patients with congenital heart disease.

Abstract
Road corrugation refers to the formation of periodic, transverse ripples on unpaved road surfaces. It forms spontaneously on an initially flat surface under heavy traffic and can be considered to be a type of unstable growth phenomenon, possibly caused by the local volume contraction of the underlying soil due to a moving vehicle's weight. In the present work, we demonstrate a possible mechanism for road corrugation using experimental data of soil consolidation and numerical simulations. The results indicate that the vertical oscillation of moving vehicles, which is excited by the initial irregularities of the surface, plays a key role in the development of corrugation.

Abstract
Abstract
Introduction
As inappropriate Internet usage has been increasing, various problems were observed, particularly in adolescence. For example, excessive Internet use might lead to absenteeism for high school students. This study aimed to examine the association between Internet usage and some difficulties of commute, such as tardy and absence for school in 4th to 9th-grade students.
Methods
Study participants were all students of the 4th-9th grade in Japanese rural public schools and their parents. In 2018 a self-reported survey was conducted. The questionnaire contained items about Internet usage, such as duration and family rules, and the current situation about commuting to school. The parents answered the same questions about their children and also responded to their own Internet usage time. The answers about their commute to school “tardy more than once a week”, “sometimes absent” and “have experience of school absenteeism” were categorized as “school absence”. The duration of Internet use was categorized every 2 hours as “never”, “0-2hrs (reference) ”, “2-4hrs” and “over 6hrs”. Multiple logistic regression analyses were performed to examine the associations between the duration of Internet use and the absence of school adjusting by covariates.
Results
Study participants were 6,031 students and 5,525 guardians participated, and response rates were 87.8%, and 80.5%, respectively. The number of “school absence” case was 429 (7.2%). The “school absence” was significantly associated with the duration of Internet use, and these relationships grew stronger as the period got longer. Odds ratio and 95% confidence interval of “over 6hrs” were 4.1 and 2.9-5.6, respectively. The parents’ own Internet usage time was also associated with their children’s school absence.
Conclusions
The longer students used the Internet, the higher the risk of school absence. Own Internet usage time of parents was also associated with children's commuting to school.
Key messages
Excessive Internet use might induce absenteeism in younger adolescents as well as older adolescents. Few studies have examined the association between Internet use and absenteeism.

Abstract
Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare type of lung cancer, accounting for 3% of all lung cancers. The prognosis is poor and the standard therapy has not been well established. Herein, we report a case of advanced LCNEC of the lung that responded to nivolumab. The patient was a 62-year old man with stage IVB LCNEC of the lung. The disease progressed following the administration of second-line chemotherapy, and he was treated with nivolumab 3 mg/kg as the third-line treatment. Although treatment was ceased after two cycles due to interstitial pneumonia, the disease remained stable for approximately six months under observation. There was no other adverse event related to nivolumab. Following patient mortality from tumor progression, PD-L1 expression was observed to be negative (tumor proportion score <1%) by a re-examination of the primary biopsy specimen. The case herein suggests that nivolumab may be a possible treatment option for LCNEC.

Abstract
Background:Treatment of rheumatoid arthritis (RA) is based on drug therapy. With the increasing number of effective drugs being authorized for use and generic drugs becoming available in the market, patients with RA now have an abundance of drugs as treatment options.Objectives:To conduct a survey of RA patients to evaluate their knowledge about the prescribed drugs, their names, and the respective categories.Methods:In 2014 and 2018, two different surveys were done in which RA patients were interviewed regarding the name of biologics (trade name) and other oral medications (category and trade name of anti-rheumatic drugs, steroid drugs and anti-inflammatory analgesics). The results of the two investigations are compared in this study.Results:A total of 135 (34 men and 101 women) and 184 patients (31 men and 153 women) were interviewed in the surveys done in 2014 and 2018, respectively. In the 2014 survey, the mean age of the patients was 58.5 years (range: 25-88 years), while in the 2018 survey, the mean age of the patients was 61.0 years (range: 14-84 years). The various biologics prescribed to the patients who participated in the 2014 vs. 2018 surveys were as follows: infliximab (27 vs. 22), etanercept (11 vs. 9), adalimumab (14 vs. 16), tocilizumab (43 vs. 71), abatacept (29 vs. 46), golimumab (7 vs. 11), certolizumab-pegol (4 vs. 3), sarilumab (0 vs. 2), and tofacitinib (0 vs. 5), respectively. The number of patients who were prescribed various categories of oral medications, as stated in the 2014 vs 2018 surveys, was as follows: anti-rheumatic drugs, 104 (77.0%) vs. 131 (71.2%); steroid drugs, 36 (26.7%) vs. 44 (23.9%); and anti-inflammatory analgesics, 49 (36.3%) vs. 61 (33.2%), respectively. The number of patients that took medications without any knowledge about the drug name or its category, as reported in the 2014 vs. 2018 surveys was as follows: anti-rheumatic drugs, 24 (23.1%) vs. 42 (32.1%); steroid drugs, 11 (30.1%) vs. 24 (54.5%); and anti-inflammatory analgesics, 15 (30.6%) vs. 17 (27.9%), respectively. In the corresponding years, the number of patients who responded negatively to the question whether they knew about the trade name of the biologics prescribed to them was 15 (11.1%) and 26 (14.1%), in the 2014 and 2018 surveys, respectively. The mean age of the patients who expressed lack of knowledge with respect to the trade name of the biologics prescribed to them was 67.3 and 69.5 years old, in the 2014 and 2018 surveys, respectively; thus suggesting the impact of old age on awareness about prescribed drugs. Many of the biologics prescribed to these patients were intravenous drip formulations, and only one patient was prescribed self-administered subcutaneous injection formulation. This implied that the majority of patients who expressed lack of knowledge regarding the trade name of the biologics were administered the drug by health-care providers at the hospital.Conclusion:Our investigation about RA patients’ understanding of the trade names and category of the drugs they were administered revealed that 20 to 50% of the patients were unaware about the oral medications they were receiving. In particular, there were many patients who had misinterpreted steroidal drugs as analgesics. In addition, approximately 10% of the patients lacked an understanding of drugs that require cautious use due to their potential for causing adverse events. For those biologics administered at the hospital by health-care providers, the patients had a lack of inclination to learn the drug name. In today’s era, with the emergence of generic drugs and an increase in the drug categories, it is not easy for the aging patients to understand and remember information about the prescription drugs. Hence, it is necessary to come up with measures to tackle this situation.Disclosure of Interests:None declared

Abstract
Quasiperiodic oscillations can occur in nonequilibrium systems where two or more frequency components are generated simultaneously. Many studies have explored the synchronization of periodic and chaotic oscillations; however, the synchronization of quasiperiodic oscillations has not received much attention. This study experimentally documents forced synchronization of the quasiperiodic state and the internally locked state of a thermoacoustic oscillator system. This system consists of a gas-filled resonance tube with a nonuniform cross-sectional area. The thermoacoustic oscillator was designed and built in such a way that nonlinear interactions between the fundamental acoustic oscillation mode and the third mode of the gas column are controlled by a temperature difference that is locally created in the resonance tube. Bifurcation diagrams were mapped out by changing the forcing strength and frequency. Separated Arnold tongues were found and both modes were entrained to the external force through complete synchronization. A saddle-node bifurcation was observed in the route from partial to complete synchronization when the forcing strength was relatively weak. However, a Hopf (torus-death) bifurcation was observed when the forcing was relatively strong. In the internally locked state, the bifurcation occurred after the internal locking was broken down by the external force.

Abstract
Most metastatic lung tumors display well-defined, round, multiple nodular shadows, whereas the presence of diffuse ground-glass opacities on chest computed tomography generally suggests non-malignant conditions. Here, we report an unusual case of pulmonary metastasis from gastric cancer in which diffuse ground-glass opacities were observed in all lung segments. A 59-year-old man with a 3-month history of worsening chest pain and shortness of breath was referred to the pulmonary clinic. Chest computed tomography revealed low attenuation areas, suggesting emphysema, along with diffuse ground-glass opacities and interlobular septal thickening in both lungs. A transbronchial lung biopsy specimen revealed signet-ring cell carcinoma infiltrating the alveolar septa. Immunohistochemical staining of the cancer cells was positive for CDX-2, cytokeratin 7, and cytokeratin 20, and negative for surfactant apoprotein-A, TTF-1, and Napsin A. Gastrointestinal endoscopy revealed an ulcerative tumor in the stomach, and a biopsy from the tumor demonstrated malignant cells with similar morphology and immunophenotypes as those in the lungs. The final diagnosis was diffuse lung metastasis from gastric cancer. Our case shows that although multiple, well-defined nodules are typically considered to be the classic presentation of pulmonary metastasis, clinicians should also be aware of the possibility of pulmonary metastasis presenting as diffuse ground-glass opacities.

Abstract
Malignant pleural mesothelioma (MPM) is a rare and highly aggressive tumor. Nivolumab showed durable antitumor effect in patients with recurrent MPM and was approved for those patients in Japan in 2018. Immune related adverse event (irAE) is occurred in various organs and is suggestive to be related to better outcome of nivolumab. Frequency of hematological irAE is low and there are few reports about hematological irAE and association between irAE and outcome of nivolumab in patients with MPM. We present a case of recurrent MPM who responded to nivolumab treatment and experienced nivolumab-induced immune thrombocytopenia (ITP). Although high dose dexamethasone was administered and platelet count increased transiently, re-administration of dexamethasone was required to maintain normal count of platelet. The careful and intensive management of ITP treatment is necessary in cases who show no response or relapse to initial glucocorticoids treatment. This is the first report about nivolumab-induced ITP and association with response to nivolumab in MPM. Frequency of hematological immune related adverse event (irAE) is low and there are only a few reports of hematological irAE in patients with MPM. This patient needed repeated administration of dexamethasone for nivolumab-induced immune thrombocytopenia (ITP) treatment. Careful and intensive management of ITP treatment is necessary in patients who show no response or who relapse after initial glucocorticoid treatment. A clinical response to nivolumab was observed in this patient. This is the first report of nivolumab-induced ITP and its association with response to nivolumab treatment in a patient with MPM.

Abstract
Corynebacterium simulans was first reported in 2000. Although it is a member of the normal skin flora, some cases of C. simulans infection have been reported. Other Corynebacterium spp. rarely cause chronic pyogenic spondylitis, and pyogenic spondylitis caused by C. simulans has not been reported at all. Here we report a case of acute pyogenic spondylitis due to C. simulans. A 78-year-old man with diabetes mellitus visited our hospital with a 3-day history of lower back pain and fever. Blood culture revealed C. simulans and magnetic resonance images of lumbar vertebrae showed pyogenic spondylitis. He recovered after treatment by vancomycin for 9 weeks and was discharged home. No recurrence has been observed for half a year. This is likely the first reported case of pyogenic spondylitis by C. simulans. In general, Corynebacterium spp. cause chronic pyogenic spondylitis, but this case showed an acute course.

Abstract
Abstract
Background
Prognostic impact of serum uric acid (UA) levels in patients with heart failure (HF) remains to be fully elucidated, as previous studies were inconclusive with small study sample sizes. Furthermore, although the J-curve relationship between serum UA levels and cardiovascular events has been suggested in patients with hypertension and those with diabetes, it is still unclear whether this is also the case for patients with HF.
Purpose
We examined the prognostic impacts of serum UA levels in HF patients, using the database of our Chronic Heart Failure Registry and Analysis in the Tohoku district (CHART)-2 Study, the largest multicenter, prospective, observational cohort study for cardiovascular patients with HF or those at risk of HF in Japan (N=10,219).
Methods
First, we determined the cut-off value of serum UA levels at baseline by the Classification and Regression Tree (CART). Then, we divided 4,652 consecutive HF patients in the CHART-2 Study into 4 groups; G1 (<3.8 mg/dL, N=313), G2 (3.8–7.1 mg/dL, N=3,070), G3 (7.2–9.2 mg/dL, N=1,018), and G4 (≥9.3 mg/dL, N=251). Among the 4 groups, we compared clinical characteristics and incidence of all-cause death, HF hospitalization, and a composite of all-cause death and HF hospitalization.
Results
Mean age in G1, G2, G3, and G4 was 71±12, 69±12, 68±13, and 69±15 years, respectively (P<0.001). G1 was characterized by a significantly high prevalence of women as compared with G2, G3 and G4 (59, 32, 24 and 23%, respectively). Serum creatinine levels (0.8±0.4, 0.9±0.4, 1.2±0.6 and 1.4±0.8 mg/dL, respectively), prevalence of atrial fibrillation (34, 39, 45 and 50%, respectively), and diuretics use (36, 45, 67, 89%, respectively) increased from G1, G2, G3 to G4 (all P<0.001), while left ventricular ejection fraction decreased from G1, G2, G3 to G4 (59±15, 58±15, 54±15, and 52±17%, respectively, P<0.001). Median BNP levels were comparably low in G1 and G2 and then increased to G3 and G4 (94.4, 91.5, 130 and 192.5 pg/mL, respectively, P<0.001). As a HF etiology, prevalence of ischemic heart disease was highest in G2 and lowest in G4 (48, 52, 48, 38%, respectively, P<0.001), while that of dilated cardiomyopathy increased from G1, G2, G3 to G4 (11, 12, 16 and 20%, respectively, P<0.001). During the median follow-up period of 6.3 years, in G1, G2, G3 and G4, 111 (35%), 905 (29%), 370 (36%) and 139 (55%) patients died and 79 (25%), 729 (24%), 300 (29%) and 115 (46%) experienced HF hospitalization, respectively (both P<0.001). Cox proportional hazard models adjusted for clinical backgrounds showed that, as compared with G2, both G1 and G4 had increased risk for all-cause death, HF hospitalization and a composite of all-cause death, and HF hospitalization, indicating the J-curve relationship between serum UA levels and prognosis (Figure).
Prognostic impacts of serum UA levels
Conclusions
Both decreased and increased UA levels were associated with increased incidence of death and HF hospitalization in HF patients.
