Abstract
Ever since the first image of a coral reef was captured in 1885, people worldwide have been accumulating images of coral reefscapes that document the historic conditions of reefs. However, these innumerable reefscape images suffer from perspective distortion, which reduces the apparent size of distant taxa, rendering the images unusable for quantitative analysis of reef conditions. Here we solve this century-long distortion problem by developing a novel computer-vision algorithm, ReScape, which removes the perspective distortion from reefscape images by transforming them into top-down views, making them usable for quantitative analysis of reef conditions. In doing so, we demonstrate the first-ever ecological application and extension of inverse-perspective mapping-a foundational technique used in the autonomous-driving industry. The ReScape algorithm is composed of seven functions that (1) calibrate the camera lens, (2) remove the inherent lens-induced image distortions, (3) detect the scene's horizon line, (4) remove the camera-roll angle, (5) detect the transformable reef area, (6) detect the scene's perspective geometry, and (7) apply brute-force inverse-perspective mapping. The performance of the ReScape algorithm was evaluated by transforming the perspective of 125 reefscape images. Eighty-five percent of the images had no processing errors and of those, 95% were successfully transformed into top-down views. ReScape was validated by demonstrating that same-length transects, placed increasingly further from the camera, became the same length after transformation. The mission of the ReScape algorithm is to (i) unlock historical information about coral-reef conditions from previously unquantified periods and localities, (ii) enable citizen scientists and recreational photographers to contribute reefscape images to the scientific process, and (iii) provide a new survey technique that can rigorously assess relatively large areas of coral reefs, and other marine and even terrestrial ecosystems, worldwide. To facilitate this mission, we compiled the ReScape algorithm into a free, user-friendly App that does not require any coding experience. Equipped with the ReScape App, scientists can improve the management and prediction of the future of coral reefs by uncovering historical information from reefscape-image archives and by using reefscape images as a new, rapid survey method, opening a new era of coral-reef monitoring.

Abstract
A 55-year-old man was referred for the close examination of an abdominal mass noted on abdominal ultrasonography during a physical examination. A contrast-enhanced computed tomography(CT)scan of his abdomen revealed a 36-mm heterogeneously contrast-enhanced mass on the left side of the aorta. He was referred for laparoscopic tumor resection without preoperative histological examination. The tumor was identified from the dorsal aspect of the mesentery of the transverse colon and was resected only because it was detachable from the duodenum. A temporary abnormal hypertension was observed intraoperatively. However, he exhibited a favorable postoperative course and was discharged on the 8th postoperative day. Grossly, it was a nodular tumor with a diameter of 38 mm. Histopathological examination revealed that the tumor cells having abundant cytoplasm formed large foci and were surrounded by sinusoidal vessels. Immunohistochemistry results were positive for chromogranin A, synaptophysin, and neural cell adhesion molecule; thus, paraganglioma was diagnosed. Herein, we report a case of laparoscopic resection of an asymptomatic paraganglioma.

Abstract
INTRODUCTION Malignant melanoma in the male breast is extremely rare. Here we report a case of malignant melanoma in which a small cystic lesion in the male breast gradually increased during follow-up and was difficult to distinguish from breast cancer. CASE A 65-year-old male was diagnosed with a tumor in the right breast and was referred to our department for further examination. At 42 years of age, he underwent tumor resection of a malignant melanoma of the abdominal skin. Mammary ultrasonography showed a 0.6 cm cystic mass in his right breast. Eight months later, the right breast mass had increased to 1.4 cm, and a core needle biopsy suggested breast cancer. Total mastectomy with axillary lymph node dissection was performed. HE staining of the resected tumor showed intranuclear inclusion bodies and some large nucleoli. On the basis of various immunostaining methods, malignant melanoma was diagnosed instead of breast cancer. After surgery, adjuvant chemotherapy with molecularly targeted drugs was administered. DISCUSSION This might have been a case of male breast metastasis of malignant melanoma with very late recurrence.

Abstract
Key Clinical Message EDTA-dependent pseudothrombocytopenia as well as myelosuppression should be suspected when thrombocytopenia occurs in patients with autoimmune disease during chemotherapy. Abstract A patient with pancreatic cancer and ulcerative colitis developed transient ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia with exacerbation of ulcerative colitis during chemotherapy. Unfortunately, pseudothrombocytopenia could not be immediately detected because thrombocytopenia was masked by a reasonable time course of adverse events associated with chemotherapy and ulcerative colitis recurrence. When thrombocytopenia occurs during chemotherapy, especially in patients with autoimmune diseases, EDTA-dependent pseudothrombocytopenia and bone marrow suppression caused by anti-cancer agents should be suspected.

Abstract
A 78-year-old male was diagnosed with a primary gastric B-cell malignant lymphoma and metastatic lung tumor 10 years ago. He underwent chemotherapy at another hospital, achieved complete remission, and was actively undergoing follow- up. He presented to our hospital with a 1-month history of a bulge in his right lower abdomen. CT revealed thickening of the ascending colon and dilatation of the oral intestine. He was diagnosed with ascending colon cancer and underwent right hemicolectomy. The subsequent pathological examination revealed a collision tumor involving diffuse, large B-cell lymphoma and well-differentiated adenocarcinoma. He was discharged from our hospital and received chemotherapy at another institution. Unfortunately, the patient died of interstitial pneumonia 31 months postoperatively. This report describes the resection of a collision tumor involving ascending colon cancer and malignant lymphoma. Surgical treatment combined with postoperative chemotherapy improved this patient's long-term survival.

Abstract
BACKGROUND Presenteeism is affected by work-related and individual factors. Among individual factors, the effect of combining various lifestyle habits on presenteeism is unknown. AIMS This study aimed to determine the relationship between changes in multiple good lifestyle habits with a change in presenteeism and to examine the effect of psychological factors on this relationship. METHODS We performed a 1-year retrospective cohort study on employees of large Japanese companies. Data were collected from health check-ups and a self-administered questionnaire. Changes in presenteeism were measured using the Quality and Quantity method. Changes in lifestyle habits were measured using a modified form of Breslow's seven health practices. Psychological factors were measured using the Kessler 6-Item Psychological Distress Scale. Linear regression was used for statistical analysis. RESULTS The number of practised lifestyle habit changes was negatively correlated with a change in presenteeism. This result was consistent when adjusted for age, sex and company (B, -0.010; P < 0.05), but became non-significant when additionally adjusted for psychological distress (B, -0.006). When analysed separately, only an improvement in the body mass index (B, -0.054; P < 0.05) and a worsened sleep habit (B, 0.040; P < 0.01) influenced a change in presenteeism. CONCLUSIONS This study suggests that improving various practised lifestyle habits in combination, rather than improving a single lifestyle habit, is beneficial in reducing presenteeism. Our finding that psychological distress altered the relationship of practised lifestyle habit changes with presenteeism indicates the importance of organizational-level intervention in presenteeism.

Abstract
Key Clinical Message A 97-year-old woman with gastrostomy had a drastic enhancement for PT-INR after starting antibiotic therapy. Possible causes include (1) vitamin K deficiency due to fasting and (2) a combination of warfarin and antibiotics. Abstract Geriatric and Asian-descent patients are more sensitive to the effects of warfarin, a key anticoagulant drug. In this report, we present a 97-year-old bedridden woman being treated with warfarin for cardiogenic cerebral infarction and femoral neck replacement as part of in-home medical care with a gastrostomy and was admitted to our hospital after developing pneumonia. We discontinued warfarin and started antibiotics, and her pneumonia-related symptoms improved. Eleven days after restarting warfarin, the patient's PT-INR surpassed the upper limit for measurement (over 10). We considered the mechanism might be triggered by (1) fasting, low nutrition status; and (2) antibiotics secondary to risk factors such as gastrostomy and being a super-geriatric woman. We recommend careful monitoring of PT-INR in patients treated with warfarin and antibiotics, especially in the setting of gastrostomy or older persons.

Abstract
BACKGROUND Advances in catheter ablation (CA) for atrial fibrillation (AF) have improved the prognosis of patients with heart failure (HF) and AF. However, its optimal timing remains to be fully elucidated. OBJECTIVES The aim of this study was to investigate the prognostic impact of early CA in patients with HF and AF hospitalized for worsening HF. METHODS From JROADHF (Japanese Registry of Acute Decompensated Heart Failure) (n = 13,238), patients with HF and AF who underwent CA within 90 days after admission for HF (early CA; n = 103) and those who did not (control; n = 2,683) were identified. Mortality was compared between these groups in the crude cohort, as well as in the propensity-matched cohort (n = 83 in each group). RESULTS In the crude cohort, all-cause mortality was significantly lower in the early CA group than in the control group (log-rank P < 0.001; HR: 0.38; 95% CI: 0.24-0.60). In the matched cohort, all-cause mortality was likewise significantly lower in the early CA group (log-rank P = 0.014; HR: 0.47; 95% CI: 0.25-0.88). Cardiovascular death and HF mortality were significantly lower in both cohorts (crude: Gray' test: P < 0.001 and P = 0.005; subdistribution HR: 0.28 [95% CI: 0.13-0.63] and HR: 0.31 [95% CI: 0.13-0.75]; matched: Gray's test: P = 0.006 and P = 0.017; subdistribution HR: 0.24 [95% CI: 0.08-0.70] and HR: 0.28 [95% CI: 0.09-0.84], respectively). CONCLUSIONS In a nationwide representative real-world cohort, CA for AF within 90 days after admission for HF was associated with improved long-term outcomes, including cardiovascular and HF death in patients with HF and AF.

Abstract
AIM Several clinical trials using intravascular ultrasound (IVUS) evaluation have demonstrated that intensive lipid-lowering therapy by statin or a combination therapy with statin and ezetimibe results in significant regression of coronary plaque volume. However, it remains unclear whether adding ezetimibe to statin therapy affects coronary plaque composition and the molecular mechanisms of plaque regression. We conducted this prospective IVUS analysis in a subgroup from the CuVIC trial. METHODS The CuVIC trial was a prospective randomized, open, blinded-endpoint trial conducted among 11 cardiovascular centers, where 260 patients with coronary artery disease who received coronary stenting were randomly allocated into either the statin group (S) or the combined statin and ezetimibe group (S+E). We enrolled 79 patients (S group, 39 patients; S+E group, 40 patients) in this substudy, for whom serial IVUS images of nonculprit lesion were available at both baseline and after 6-8 months of follow-up. RESULTS After the treatment period, the S+E group had significantly lower level of low-density lipoprotein cholesterol (LDL-C; 80.9±3.7 vs. 67.7±3.8 mg/dL, p=0.0143). Campesterol, a marker of cholesterol absorption, and oxysterols (β-epoxycholesterol, 4β-hydroxycholesterol, and 27-hydroxycholesterol) were also lower in the S+E group. IVUS analyses revealed greater plaque regression in the S+E group than in the S group (-6.14% vs. -1.18% for each group, p=0.042). It was noteworthy that the lowering of campesterol and 27-hydroxycholesterol, but not LDL-C, had a significant positive correlation with plaque regression. CONCLUSIONS Compared with statin monotherapy, ezetimibe in combination with statin achieved significantly lower LDL-C, campesterol, and 27-hydroxycholesterol, which resulted in greater coronary plaque regression.

Abstract
Developing delivery vehicles that achieve drug accumulation in the liver and transferability into hepatic stellate cells (HSCs) across the liver sinusoidal endothelium is essential to establish a treatment for hepatic fibrosis. We previously developed hyaluronic acid (HA)-coated polymeric micelles that exhibited affinity to liver sinusoidal endothelial cells. HA-coated micelles possess a core-shell structure of self-assembled biodegradable poly(l-lysine)-b-poly(lactic acid) AB-diblock copolymer (PLys+-b-PLLA), and its exterior is coated with HA through polyion complex formation via electrostatic interaction between anionic HAs and cationic PLys segments. In this study, we prepared HA-coated micelles entrapping olmesartan medoxomil (OLM), an anti-fibrotic drug, and evaluated their possibility as drug delivery vehicles. HA-coated micelles exhibited specific cellular uptake into LX-2 cells (human HSC line) in vitro. In vivo imaging analysis after intravenous (i.v.) injection of HA-coated micelles into mice revealed that the micelles exhibited high accumulation in the liver. Observation of mouse liver tissue sections suggested that HA-coated micelles were distributed in liver tissue. Furthermore, i.v. injection of HA-coated micelles entrapping OLM showed a remarkable anti-fibrotic effect against the liver cirrhosis mouse model. Therefore, HA-coated micelles are promising candidates as drug delivery vehicles for the clinical management of liver fibrosis.

Abstract
BACKGROUND Dipeptidyl peptidase-4 (DPP-4) inhibitors have been shown to exert pleiotropic effects on heart failure (HF) in animal experiments. OBJECTIVES This study sought to investigate the impact of DPP-4 inhibitors on HF patients with diabetes mellitus (DM). METHODS We analyzed hospitalized patients with HF and DM enrolled in the JROADHF (Japanese Registry Of Acute Decompensated Heart Failure) registry, a nationwide registry of acute decompensated HF. Primary exposure was the use of a DPP-4 inhibitor. The primary outcome was a composite of cardiovascular death or HF hospitalization during the median follow-up of 3.6 years according to left ventricular ejection fraction. RESULTS Out of 2,999 eligible patients, 1,130 had heart failure with preserved ejection fraction (HFpEF), 572 had heart failure with midrange ejection fraction (HFmrEF), and 1,297 had heart failure with reduced ejection fraction (HFrEF). In each cohort, 444, 232, and 574 patients received a DPP-4 inhibitor, respectively. A multivariable Cox regression model showed that DPP-4 inhibitor use was associated with a lower composite of cardiovascular death or HF hospitalization in HFpEF (HR: 0.69; 95% CI: 0.55-0.87; P = 0.002) but not in HFmrEF and HFrEF. Restricted cubic spline analysis demonstrated that DPP-4 inhibitors were beneficial in patients with higher left ventricular ejection fraction. In HFpEF cohort, propensity score matching yielded 263 pairs. DPP-4 inhibitor use was associated with a lower incidence rate of the composite of cardiovascular death or HF hospitalization (19.2 vs 25.9 events per 100 patient-years; rate ratio: 0.74; 95% CI: 0.57-0.97; P = 0.027) in matched patients. CONCLUSIONS DPP-4 inhibitor use was associated with better long-term outcomes in HFpEF patients with DM.

Background
Shorter duration of dual antiplatelet therapy after drug-eluting stent implantation is required in patients with high bleeding risk (HBR) irrespective of the presence of concomitant high thrombotic risk (HTR). The prevalence of post-stent suboptimal findings in patients with HBR remains unclear.
Purpose
To clarify the prevalence of post-stent suboptimal findings assessed by optical coherence tomography (OCT) in patients with HBR according to the presence of HTR.
Methods
A total of 607 consecutive patients with stable coronary disease, who underwent OCT imaging of the culprit lesion were included. HBR was defined based on the Academic Research Consortium for High Bleeding Risk (ARC-HBR). HTR was defined as lesions with diffuse long (≧60 mm), treated with more than three stents, chronic total occlusion or diffuse long lesion (≧32 mm) in patients with diabetes mellitus. Post-stent suboptimal OCT criteria was defined as minimum stent area (MSA) <4.5 mm2, edge dissection and stent malapposition.
Results
The prevalence of HBR was 55.8%. The prevalence of HTR was significantly higher in patients with HBR than in those without HBR (35.0 vs. 26.6%, p=0.028) (Figure A). Among patients with HBR, the prevalence of post-stent suboptimal OCT criteria was significantly higher in patients with HTR than in those without HTR (86.2 vs. 64.7%, p<0.001), mainly due to the higher prevalence of MSA <4.5 mm2 (Figure B) in patients with HTR.
Conclusions
HTR was associated with a higher prevalence of post-stent suboptimal findings among patients with HBR. The present results may suggest the importance of optimal stenting in patients with HBR, particularly in those with concomitant HTR.

Abstract
Dear Editor,Mammary Paget's disease (MPD) is an adenocarcinoma localized within the epidermis of the nipple and/or the areola of the breast, and it is as a rule associated with a carcinoma of the underlying lactiferous ducts, where it usually starts. MPD is relatively rare, observed in 0.7-4.3% of all breast cancers (1). We present a patient with MPD and atypical clinical finding as an annular plaque. A 74-year-old Japanese woman with a past medical history of hypothyroidism presented with a 6-month history of an itching plaque on the left areola. The patient had been treated with the application of topical steroids for a duration of approximately 5 months, and showed no clinical improvement. Physical examination showed a pink plaque encircling the nipple on the left areola (Figure 1, a). The right nipple and areola appeared normal (Figure 1, b). No palpable masses were detected within either breast. A 3.5 mm punch biopsy of the skin at the 6 o'clock position of the left areola was performed. Histological examination showed single and small aggregations of atypical cells with large hyperchromatic nuclei and pale-staining, ample cytoplasm throughout the epidermis. There was a lymphocytic infiltration in the dermis (Figure 1, c). Immunohistochemical studies were positive for CK7 and negative for S-100 and HMB45. With the diagnosis of MPD, the patient underwent a partial mastectomy of the left breast center area, consisting of surgical excision of the left nipple, the adjacent surrounding areolar skin, and subcutaneous tissues. Subsequently, radiation therapy for the residual breast was prepared. As has been described in detail by Kanitakis, the skin lesion develops insidiously as a scaly, fissured, or oozing erythema of the nipple and, more rarely, the areola. Advanced lesions present as a well-demarcated, round, ovoid, or polycyclic eczema-like plaque with a pink or red hue. It is occasionally slightly infiltrated and has an erosive, oozing, scaly, or crusted surface. The lesions are almost invariably unilateral, showing centrifugal spread. Retraction or ulceration of the nipple are often noted (1). The present case exhibited a very rare clinical finding of a plaque encircling the nipple, which has not been reported previously. It was initially difficult to establish the diagnosis of MPD, and biopsy was needed to obtain a definitive diagnosis. Differential diagnosis of MPD comprises eczema as atopic dermatitis or contact dermatitis, erosive adenomatosis, and malignant skin condition such as Bowen's disease, superficial basal cell carcinoma, or superficially spreading melanoma. As in the present case, individuals presenting with an annular plaque are often considered to have sebaceous hyperplasia. Sebaceous hyperplasia is a common, benign skin condition involving hypertrophy of the sebaceous glands, common in middle-aged or older adults (2). These lesions can be single or multiple and manifest as yellow, soft, small papules. These papules are occasionally seen around the nipple, forming an annular plaque. In general, sebaceous hyperplasia is described as yellow-colored papules among Caucasians. However, caution is needed, since it is characterized by skin-colored papules among some Asians.In the present case, some pigmentation (2 to 3 mm in diameter) was observed on the left nipple. Pigmented MPD have been reported, and the mechanism underlying the pigmentation is not yet fully understood, but it has been proposed that Paget cells may release melanocytic chemoattractants or basic fibroblast growth factors that stimulate the proliferation of melanocytes within the tumor nests (3). The possibility of physiological pigmentation cannot be ruled out in the present case; on the other hand, the possibility of pigmented MPD cannot be ruled out either, since no pigmentation was observed on the right nipple.

Abstract
INTRODUCTION
Glioblastoma is a brain tumor with a very poor prognosis that is highly resistant to treatment. Hiba (Thujopsis dolabrata) has been used as a building material because of its insect repellent effect and refreshing fragrance. In this study, we analyzed the antitumor effects of thujopsen, which is contained in the essential oil of hiba, and investigated its antitumor aroma therapy.Methods and
RESULTS
We investigated the anti-tumor aroma effect of hiba essential oil on glioblastoma cells (U251, T98G), gastric cancer cells (MKN45), and breast cancer cells (MCF7). The anti-tumor effect of hiba essential oil varied depending on the carcinoma, with strong inhibition of cell proliferation observed in MKN45, U251, and T98G cells. Hinokitiol in hiba essential oil has been reported to have antitumor effects, and we isolated and identified a new antitumor factor, thujopsene, by liquid chromatography analysis. In tumor cell proliferation assays, thujopsen inhibited tumor cell proliferation more rapidly and potently than hinokitiol. Comparing the reach of the two compounds, hinokitiol showed a broader anti-tumor effect than thujopsen. The expression of caspase-3 and caspase-9 was increased by thujopsen, and DARTS analysis identified PKM2 as an intracellular binding protein of thujopsen.
DISCUSSION
The present study revealed that thujopsen induces apoptosis via caspase-3 and caspase-9. Furthermore, unlike hinokitiol, thujopsen was suggested to exhibit antitumor effects mediated by PKM2.
CONCLUSION
Thujopsen is a low molecular weight compound and easily evaporates into the air, it is expected to be applied to a new glioblastoma therapy using "aroma".

Abstract
We study the temperature-dependent diffusion of many types of metal and semimetal ions in soda-lime glass using thermal relaxation ion spectroscopy, a technique that provides an electrical readout of thermally activated diffusion of charge carriers driven by built-in concentration gradients and electric fields. We measure the temperature of the onset of the motion, relevant to the long term storage of radioactive elements. We demonstrate the unique behavior of silver in soda-lime glass, enabling a thermal battery with rapid discharge of stored energy above a threshold temperature. We show that the Meyer-Neldel rule applies when comparisons of temperature-dependent diffusion rates are made between related measurements on one sample or between the same measurements on related samples. The results support a thermodynamic interpretation of the Meyer-Neldel rule as an enthalpy-entropy correlation where the Meyer-Neldel temperature (T_{MN}) is the temperature that enables liquidlike, barrier-free motion of the ions, with an upper limit set by the melting point of the host medium. This interpretation explains the observed reduction in T_{MN} by built-in electric fields in depletion layers and why the upper limit for T_{MN} for all ions is set by the glass transition temperature.

Abstract
The aim of this study was to determine the proportion of near-miss dispensing errors in hospital pharmacies in Japan. A prospective multi-center observational study was conducted between December 2018 and March 2019. The primary objective was to determine the proportion of near-miss dispensing errors in hospital pharmacy departments. The secondary objective was to determine the predictive factors for near-miss dispensing errors using multiple logistic regression analysis. The study was approved by the ethical committee at The Institute of Medical Sciences, University of Tokyo, Japan. A multi-center prospective observational study was conducted in 20 hospitals comprising 8862 beds. Across the 20 hospitals, we assessed data from 553 pharmacists and 53039 prescriptions. A near-miss dispensing error proportion of 0.87% (n = 461) was observed in the study. We found predictive factors for dispensing errors in day-time shifts: a higher number of drugs in a prescription, higher number of quantified drugs, such as liquid or powder formula, in a prescription, and higher number of topical agents in a prescription; but we did not observe for career experience level for clinical pharmacists. For night-time and weekend shifts, we observed a negative correlation of near-miss dispensing errors with clinical pharmacist experience level. We found an overall incidence of near-miss dispensing errors of 0.87%. Predictive factors for errors in night-time and weekend shifts was inexperienced pharmacists. We recommended that pharmacy managers should consider education or improved work flow to avoid near-miss dispensing errors by younger pharmacists, especially those working night or weekend shifts.

Abstract
Abstract
Background
The impact of the high triglyceride (TG) level on the characteristics of coronary plaque in nonculprit lesion remains to be elucidated.
Purpose
To clarify the association between the TG level and the characteristics of nonculprit coronary plaque in patients with stable coronary disease using optical coherence tomography (OCT).
Methods
A total of 531 consecutive patients who underwent OCT imaging of the nonculprit lesion were included. Patients were classified into either the higher TG group (non-fasting TG ≥150 mg/dL, n=197) or the lower TG group (non-fasting TG <150 mg/dL, n=334). The morphologies of nonculprit plaque assessed by OCT were compared between the two groups.
Results
The median (interquartile range) of TG in the two groups was 193.0 (168.0–244.0) mg/dL and 95.0 (75.0–120.0) mg/dL, respectively. The prevalence of layered plaque was significantly higher in the higher TG group than the lower TG group (40.1 vs. 27.5%, p=0.004), whereas the prevalence of other plaque components was comparable between the two groups (Figure 1). The prevalence of layered plaque was significantly higher in the higher TG group than in the lower TG group among patients with diabetes mellitus (DM) (44.2 vs. 28.7%, p=0.037) although it was comparable between the two groups among patients without DM (Figure 2).
Conclusion
A higher TG level was associated with a higher prevalence of layered plaque in nonculprit plaques in patients with stable coronary disease, particularly in patients with DM. The present results may partly explain the impact of TG on the progression of coronary plaque and the increased incidence of recurrent events in patients with coronary artery disease.

Abstract
AIMS Cardiac rehabilitation (CR) is an evidence-based, secondary preventive strategy that improves mortality and morbidity rates in patients with heart failure (HF). However, the implementation and continuation of CR remains unsatisfactory, particularly for outpatients with physical frailty. This study investigated the efficacy and safety of a comprehensive home-based cardiac rehabilitation (HBCR) programme that combines patient education, exercise guidance, and nutritional guidance using information and communication technology (ICT). METHODS AND RESULTS This study was a single-centre, open-label, randomized, controlled trial. Between April 2020 and November 2020, 30 outpatients with chronic HF (New York Heart Association II-III) and physical frailty were enrolled. The control group (n = 15) continued with standard care, while the HBCR group (n = 15) also received comprehensive, individualized CR, including ICT-based exercise and nutrition guidance using ICT via a Fitbit® device for 3 months. The CR team communicated with each patient in HBCR group once a week via the application messaging tool and planned the training frequency and intensity of training individually for the next week according to each patient's symptoms and recorded pulse data during exercise. Dietitians conducted a nutritional assessment and then provided individual nutritional advice using the picture-posting function of the application. The primary outcome was the change in the 6 min walking distance (6MWD). The participants' mean age was 63.7 ± 10.1 years, 53% were male, and 87% had non-ischaemic heart disease. The observed change in the 6MWD was significantly greater in the HBCR group (52.1 ± 43.9 m vs. -4.3 ± 38.8 m; P < 0.001) at a 73% of adherence rate. There was no significant change in adverse events in either group. CONCLUSIONS Our comprehensive HBCR programme using ICT for HF patients with physical frailty improved exercise tolerance and improved lower extremity muscle strength in our sample, suggesting management with individualized ICT-based programmes as a safe and effective approach. Considering the increasing number of HF patients with frailty worldwide, our approach provides an efficient method to keep patients engaged in physical activity in their daily life.

Background
Higher level of high sensitivity C-reactive protein (hsCRP) is associated with an increased risk of recurrent cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI). However, the association between hsCRP and the characteristics of non-culprit plaques in patients with STEMI remains to be elucidated.
Purpose
To clarify the morphological characteristics of non-culprit plaque in patients with STEMI according to the hsCRP levels using optical coherence tomography (OCT).
Methods
A total of 79 non-culprit plaques in 76 consecutive patients with STEMI, who underwent OCT imaging of the non-culprit plaques in a culprit vessel were included. The characteristics of non-culprit plaques assessed by OCT were compared between the higher hsCRP group (hsCRP ≥ 0.16 mg/dL, 38 plaques in 38 patients) and the lower hsCRP group (hsCRP < 0.16 mg/dL, 41 plaques in 38 patients).
Results
The prevalence of plaque with macrophage (63.2 vs. 31.7%, p = 0.006), plaque with large lipid (maximal lipid arc > 180 °) (57.9 vs. 31.7%, p = 0.018), healed plaque (50.0 vs. 26.8%, p = 0.045) and cholesterol crystal (18.4 vs. 2.4%, p = 0.045) was significantly higher in the higher hsCRP group than in the lower hsCRP group (Figure). In a multivariate analysis, the higher hsCRP was independently associated with the presence of plaque with macrophage (Odds ratio [OR], 3.031; 95% confidence interval [CI]: 1.112-8.264, p = 0.030), plaque with large lipid (OR, 2.897; 95% CI: 1.122-7.478, p = 0.026) and healed plaque (OR, 2.666; 95% CI: 1.030-6.896, p = 0.040).
Conclusions
Higher level of hsCRP is associated with a higher prevalence of vulnerable characteristics in non-culprit plaques in patients with STEMI. The present results may partly explain the pathogenesis of an increased incidence of recurrent cardiovascular events in patients with STEMI. Abstract Figure.

Abstract
BACKGROUND AND AIM Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is a fatal condition with no established treatment. Intravenous immunoglobulin (IVIG) is a unique therapy with both anti-inflammatory and anti-infective effects. Therefore, we hypothesized that IVIG may have a positive effect on AE of interstitial pneumonia. This study aimed to determine the effect of IVIG in patients with AE of fibrotic idiopathic interstitial pneumonias (IIPs), including IPF. METHODS We retrospectively analyzed consecutive patients who were diagnosed with AE of fibrotic IIPs and treated with pulse corticosteroid therapy (methylprednisolone 500-1000 mg/day for 3 days) between April 2018 and May 2021 at Kagawa Rosai Hospital and KKR Takamatsu Hospital. RESULTS This study included 52 patients with AE of fibrotic IIPs (IPF,41; fibrotic IIPs other than IPF,11). Thirteen patients received IVIG (5 g/day for 3-5 days) concurrently with pulse corticosteroid therapy. The remaining 39 patients were assigned to the control group. The survival rate on day 90 was significantly higher in the IVIG group than that in the control group (76.9% vs. 38.5%, p = 0.02). IVIG administration (odds ratio [OR], 0.11; 95% confidence interval [CI], 0.02-0.69; p = 0.02) and C- reactive protein (OR, 1.19; 95% CI, 1.06-1.33, p < 0.01) were independently associated with 90-day mortality. CONCLUSIONS The results indicate that administration of IVIG may improve the survival of patients with AE of fibrotic IIPs. We are now conducting a prospective study to confirm the effect of IVIG on AE of IPF since May 2022 (jRCT1061220010).

Abstract
INTRODUCTION The importance of genetic counseling has been noted for hereditary breast cancer. We report the cases of two 32-year-old woman, unmarried, BRCA mutation-positive patients. CASES In Case 1, the chief complaint was awareness of a right breast mass. There was a family history of breast cancer(3 previous cases in the family). The BRCA2 mutation was positive during the BRACAnalysis test. Right breast mastectomy and axillary dissection were performed. Genetic counseling was performed postoperatively, and her eggs were cryopreserved. In Case 2, the chief complaint was calcification of the right breast. She also had a family history of breast cancer(3 previous cases in the family). The BRCA1 mutation was positive during the BRACAnalysis test. Nipple-sparing mastectomy and sentinel lymph node biopsy were performed, and the pathological diagnosis was DCIS. After genetic counseling, she did not desire the cryopreservation of her eggs. DISCUSSION In these cases, the histological type, stage, subtype, BRCA mutation site, etc., were different from each other, and detailed support by genetic counseling was taken according to each medical condition such as surgery and postoperative adjuvant therapy.

Abstract
Crop field trials were conducted to investigate the residues of sprayed pesticides on the different sizes of tomatoes. Pesticide residue data in tomatoes varied due to different locations of the three crop fields selected and/or physicochemical properties of the three pesticides tested. The pesticide residue levels in the medium- and small-sized tomatoes were 1.5 and 2.4 times higher than the level in large-sized tomatoes under similar spray conditions, whereas amount of pesticides adhered per unit surface area were approximately equal among all three sizes of tomatoes. The results of this study suggested that the differences in pesticide residue levels were due to differences in the degree of specific surface area of each tomato size. Resultant residue data of medium-sized tomatoes demonstrated a proportional relationship between pesticide residue levels and the specific surface area of tomatoes.

Abstract
INTRODUCTION The optimal indication for the nucleic acid amplification test (NAAT) in areas with low endemicity for coronavirus disease 2019 (COVID-19) is unclear. This study aimed to identify patients who should undergo the NAAT for COVID-19 diagnosis. METHODS We retrospectively analyzed the clinical data of patients with suspected COVID-19 who underwent NAAT between October 5, 2020, and May 31, 2021 in our institution. RESULTS A total of 1238 patients were enrolled and NAAT positive results were observed in 40 patients (3.2%). The NAAT positivity rate was 34.3% (23/67) in patients with a history of close contact and 1.5% (17/1171) in patients without a history of close contact. Olfactory/gustatory dysfunction and a history of stay in other prefectures were independent risk factors of COVID-19 in patients without a history of close contact. On the other hand, the NAAT positivity rate was only 0.7% (8/1073) in patients without olfactory/gustatory dysfunction and a history of stay in other prefectures. Among them, the group without respiratory symptoms/sign had only one NAAT-positive case (0.1%: 1/1073). CONCLUSIONS This study revealed that a history of close contact, olfactory/gustatory dysfunction, and a history of stay in other prefectures are key eligibility criteria for NAAT in areas with relatively few patients with COVID-19. On the other hand, NAAT may not be necessary in cases without all of these factors and respiratory symptoms/sign.

Abstract
OBJECTIVES To investigate the association of loneliness and its component subscales with the risk of dementia in a general Japanese older population. METHOD A total of 1,141 community-dwelling Japanese residents aged ≥65 years without dementia were prospectively followed up for a median 5.0 years. We evaluated any loneliness and its component subscales-namely, social and emotional loneliness-by using the 6-item de Jong Gierveld Loneliness Scale. Cox proportional hazards models were used to estimate hazard ratios (HRs) of each loneliness type on the risk of dementia controlling for demographic factors, lifestyle factors, physical factors, social isolation factors, and depression. RESULTS During the follow-up, 114 participants developed dementia. The age- and sex-adjusted incidence rate of dementia was significantly greater in participants with any loneliness and emotional loneliness than those without. The multivariable-adjusted HRs (95% confidence intervals) of participants with any loneliness and emotional loneliness on incident dementia were 1.61 (1.08-2.40) and 1.65 (1.07-2.54), respectively, as compared to those without. However, there was no significant association between social loneliness and dementia risk. In subgroup analyses of social isolation factors, excess risks of dementia associated with emotional loneliness were observed in participants who had a partner, lived with someone, or rarely communicated with relatives or friends, but such association was not significant in participants who had no partner, lived alone, or frequently communicated with friends or relatives. DISCUSSION The present study suggested that loneliness, especially emotional loneliness, was a significant risk factor for the development of dementia in the general older population in Japan.

Abstract
AIM Amyloidosis is a systemic or localized disease of protein deposition characterized by amorphous eosinophilic morphology and positivity of Congo Red staining. The typing of amyloidosis is becoming increasingly important because therapeutic agents for each amyloidosis type have been developed. Herein, the authors review the autopsy cases at an institution to reveal the putative Japanese characteristics of each amyloidosis type and evaluate the clinicopathological significance of each type. MATERIALS AND METHODS A total of 131 autopsy cases of systemic and localized amyloidosis were retrieved for classification by immunohistochemistry. Immunohistochemistry for transthyretin, amyloid A (AA), immunoglobulin light-chain kappa and lambda, and β2-microglobulin was performed for all cases. RESULTS The 131 amyloidosis cases were classified as follows: 71 cases (54.2%) of transthyretin amyloidosis, 32 cases (24.4%) of AA amyloidosis, 8 cases (6.1%) of light-chain amyloidosis, and 5 cases (3.8%) of β2-microglobulin amyloidosis, along with 15 equivocal cases (11.5%). All cases showed myocardial involvement of amyloidosis. Histopathologically, the transthyretin type was significantly associated with the interstitial and nodular patterns, and with the absence of the perivascular and endocardial patterns. The AA type was significantly associated with the perivascular and endocardial patterns, and with the absence of the nodular pattern. CONCLUSION The authors revealed the putative characteristics of cardiac amyloidosis in Japan by using autopsy cases. About 90% of amyloidosis cases were successfully classified using only commercially available antibodies.

Abstract
The diagnosis of leptomeningeal metastases is sometimes difficult when the cytology of cerebrospinal fluid is negative. We report a rare case of leptomeningeal metastases that required differentiation from paraneoplastic limbic encephalitis. A 67-year-old man with extensive-stage small cell lung cancer was admitted for a sudden decrease in the level of consciousness. He suffered memory disturbances that began the day before admission. Diffusion-weighted and fluid-attenuated inversion recovery images of brain magnetic resonance imaging (MRI) showed bilateral symmetric areas of hyperintensity in the hippocampus, amygdala, insular cortex, and medial temporal lobe; contrast enhancement was positive. Cytology of the cerebrospinal fluid (CSF) was negative. Anti-N-methyl-d-aspartate receptor antibody and herpes simplex virus DNA were not detected in the CSF. Paraneoplastic Limbic encephalitis was suspected due to his symptoms and brain MRI scan. The patient developed generalized seizures after admission. High-dose methylprednisolone and intravenous immune globulin were administered, but his condition did not improve. Uncontrollable seizures persisted and he died in the hospital at day 13. Autopsy revealed leptomeningeal metastasis and invasion of cancer cells into the limbic system. Contrast-enhanced MRI should be performed even if limbic encephalitis is suspected, and leptomeningeal metastases should be suspected if the lesions are enhanced.

Abstract
BACKGROUND The risk prediction of incident atrial fibrillation (AF) is useful to prevent AF and its complications. The aim of this study is to develop a new risk prediction model for incident AF using the prospective longitudinal data from a general Japanese population.Methods and Results:A total of 2,442 community-dwelling AF-free residents aged ≥40 years were followed up from 1988 to 2012 (46,422 person-years). The development of AF was confirmed by a standard 12-lead electrocardiogram at repeated health examinations and by medical records at clinics or hospitals. The risk prediction model for incident AF was developed using a Cox proportional hazards model. During the follow up, 230 AF events were confirmed. Age, sex, systolic blood pressure, waist circumference, estimated glomerular filtration rate, abnormal cardiac murmur, high R-wave amplitude, and arrhythmia other than AF were selected for inclusion in the model. This model showed good discrimination (Harrell's c statistics: 0.785) and calibration (Greenwood-Nam-D'Agostino test: P=0.87) for AF risk at 10 years. CONCLUSIONS The new risk prediction model showed good performance on the individual risk assessment of the future onset of AF in a general Japanese population. As this model included commonly used clinical parameters, it may be useful for determining the requirements for the careful evaluation of AF, such as frequent electrocardiogram examinations in clinical settings, and subsequent reductions in the risk of AF-related complications.

Abstract
Tumor-infiltrating lymphocytes (TILs) are a potent source for obtaining tumor-reactive T cell receptors (TCRs). Although comprehensive methods to analyze the TCR repertoire in TILs have been reported, the evaluation system for TCR-reactivity to endogenously expressed antigen in tumor cells remains laborious and time consuming. Consequently, very limited numbers of TCRs in TILs have been analyzed for their reactivity to tumor cells. In this study, we developed an efficient evaluation system for TCR function designated c-FIT (comprehensive functional investigation of TCRs) to analyze TCR reactivity. The c-FIT system enabled us to analyze up to 90 TCRs for their reactivity to tumor cells by a single assay within a month. Using c-FIT, we analyzed 70 TCRs of CD8+ TILs derived from two breast cancer patients and obtained 23 TCRs that reacted to tumor cells. Surprisingly, although two TCRs were HLA class I-restricted, the remaining 21 TCRs were non-HLA-restricted. Thus, c-FIT can be applied for monitoring multiple conventional and unconventional antigen-specific killer T cells in TILs, leading to the development of new designs for more effective T-cell-based immunotherapies.

Abstract
Postoperative adhesion remains a problem in surgery and causes postoperative complications. Laparoscopic surgery is now common, making it increasingly important to develop injectable formulations of adhesion barriers that can be applied during such surgeries. Temperature-responsive injectable polymer (IP) systems exhibiting a sol-to-gel transition in response to temperature are promising candidates as effective adhesion barriers that can be applied conveniently during laparoscopic surgery. We previously developed IP systems exhibiting temperature-responsive irreversible gelation based on a triblock copolymer of poly(ε-caprolactone-co-glycolic acid) (PCGA) and poly(ethylene glycol) (PEG) (PCGA-b-PEG-b-PCGA: tri-PCG) and a tri-PCG derivative with acrylate groups at the termini (tri-PCG-acryl). A mixture of tri-PCG-acryl micelle solution and tri-PCG micelle solution containing polythiol exhibited an irreversible sol-to-gel transition in response to a temperature increase. The gel contains partial covalent cross-linking, and the degradation and physical properties of these IP hydrogels can easily be controlled by changing the mixing ratio of tri-PCG-acryl in the formulation. In this study, we investigated the effect of physical properties of the IP hydrogel on the efficacy of adhesion prevention using our IP system containing various amounts of tri-PCG-acryl. Our results show that an IP system with lower physical strength and rapid degradation reduces adhesion more effectively. Chymase plays a crucial role in exacerbating adhesion formation, and a peptide derivative-type chymase inhibitor (CI), Suc-Val-Pro-PheP(OPh)2, was previously reported to prevent adhesion. We thus investigated the concomitant use of this CI with our IP system using two methods: separate administration of the CI and IP and entrapping the CI in the IP hydrogel. IP systems with separately administrated CI provided better results than the administration of an IP system entrapping the CI or sole IP systems. These findings suggest that the pharmacological effect of the CI and a physical barrier generated by our IP system effectively prevents adhesion.

Abstract
BACKGROUND natriuretic peptide is associated with myocardial fibrosis in animal models and among patients with heart disease. However, it remains unclear whether serum N-terminal pro-B-type peptide (NT-proBNP) levels are associated with histopathologically proven myocardial fibrosis among individuals without apparent heart disease. This study aimed to evaluate the association between serum NT-proBNP levels and the histopathologically estimated myocardial fibrotic area in autopsied samples from a community. METHODS we selected 63 cases without apparent heart disease with available data of serum NT-proBNP concentrations within six years before death (average age: 82 years; male: 52%) from autopsied cases in a community, and evaluated the percentage areas of myocardial fibrosis in four cardiac segments from each case (i.e. 252 cardiac segments in total). The association between serum NT-proBNP levels and the percentage area of myocardial fibrosis was estimated using a linear mixed model for repeated measures. RESULTS serum NT-proBNP levels were positively correlated with myocardial fibrotic area [Pearson's correlation coefficient: r = 0.49 (95% confidence interval: 0.28-0.66), p <0.001]. Serum NT-proBNP levels were significantly associated with the percentage areas of myocardial fibrosis after adjusting for potential confounding factors. There was no evidence of heterogeneity in the association between the subgroups with and without reduced estimated glomerular filtration rate (<60 mL/min/1.73 m2). CONCLUSIONS the present study demonstrated that elevated serum NT-proBNP levels were associated with the histopathologically measured myocardial fibrotic area in autopsied cases from a community. These findings may help clarify the association between elevated serum NT-proBNP levels and myocardial fibrosis and their influence on prognosis.

Abstract
BACKGROUND Epidemiological evidence has shown that serum N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations, a diagnostic biomarker for heart failure, are positively associated with cardiovascular risk. Since NT-proBNP in serum is excreted in urine, it is hypothesized that urinary NT-proBNP concentrations are correlated with serum concentrations and linked with cardiovascular risk in the general population. METHODS A total of 3060 community-dwelling residents aged ≥ 40 years without history of cardiovascular disease (CVD) were followed up for a median of 8.3 years (2007-2015). Serum and urinary concentrations of NT-proBNP at baseline were compared. The hazard ratios (HRs) and their 95% confidence intervals (CIs) for the association between NT-proBNP concentrations and the risk of developing CVD were computed using the Cox proportional hazards model. RESULTS The median values (interquartile ranges) of serum and urinary NT-proBNP concentrations at baseline were 56 (32-104) pg/mL and 20 (18-25) pg/mL, respectively. There was a strong quadratic correlation between the serum and urinary concentrations of NT-proBNP (coefficient of determination [R2] = 0.72): urinary concentrations of 20, 27, and 43 pg/mL were equivalent to serum concentrations of 55, 125, and 300 pg/mL, respectively. During the follow-up period, 170 subjects developed CVD. The age- and sex-adjusted risk of CVD increased significantly with higher urinary NT-proBNP levels (P for trend < 0.001). This association remained significant after adjustment for traditional cardiovascular risk factors (P for trend = 0.009). The multivariable-adjusted risk of developing CVD almost doubled in subjects with urinary NT-proBNP of ≥ 43 pg/mL as compared to those with urinary NT-proBNP of ≤ 19 pg/mL (HR 2.07, 95% CI 1.20-3.56). CONCLUSIONS The present study demonstrated that urinary NT-proBNP concentrations were well-correlated with serum concentrations and were positively associated with cardiovascular risk. Given that urine sampling is noninvasive and does not require specially trained personnel, urinary NT-proBNP concentrations have the potential to be an easy and useful biomarker for detecting people at higher cardiovascular risk.

Abstract
Modulated electro-hyperthermia (mEHT) is a new treatment modality developed to overcome the problems associated with traditional hyperthermia; mEHT uses a precise impedance-matched system and modulated radiofrequency current flow to malignant tumors. It selects the malignant cells based on their biophysical differences, due to their high metabolic rate, individual (autonomic) behavior and membrane status. The aim of the present study was to report the outcomes of mEHT in the treatment of advanced breast cancer. mEHT was examined in 10 patients with advanced metastatic breast cancer and recurrent disease, who were considered incurable by standard therapy protocols. Of the 10 patients, partial response was achieved in 3, disease stability in 3, and progressive disease in 4; however, their quality of life was improved based on their subjective reports. No adverse effects were observed in any of the 10 patients. The present study demonstrated the feasibility of mEHT as a possible therapy for advanced breast cancer cases when standard therapies fail. Moreover, mEHT had no side effects and may be combined with various treatments for long-term therapy.

Abstract
BACKGROUND Atrial fibrillation (AF) is a common arrhythmia in the elderly, and causes complications such as cardioembolic stroke. Serum high-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation, has been reported to be a risk factor for developing AF in Western countries. However, few community-based studies have examined this issue in general Asian populations.Methods and Results:A total of 2,510 community-dwelling Japanese participants aged ≥40 years without a history of AF were divided into 4 groups according to the sex-specific quartiles of serum hs-CRP concentrations (Q1, lowest and Q4, highest) and followed up for 24 years. The hazard ratios and their 95% confidence intervals for the development of AF were estimated using a Cox proportional hazards model. During the follow up, 234 subjects developed AF. The risk of AF increased significantly with elevating serum hs-CRP levels after adjustment for potential confounding factors (hazard ratio [95% confidence interval], Q1, 1.00 [reference]; Q2, 1.26 [0.83-1.92]; Q3, 1.77 [1.18-2.66]; and Q4, 1.89 [1.24-2.86]; P for trend <0.001). CONCLUSIONS The study findings suggest that elevated serum hs-CRP levels are an independent risk factor for the development of AF in a general Japanese population.

Abstract
Introduction Serum N-terminal pro–B-type natriuretic peptide (NT-proBNP) levels have been associated with the progression of kidney impairment among patients with chronic kidney disease (CKD), but only a few studies have investigated the association between serum NT-proBNP levels and incident CKD in general populations. Methods A total of 2486 Japanese community-dwelling residents ≥40 years of age without CKD at baseline were followed up by repeated annual health examinations for 10 years. Participants were divided into 4 groups according to serum NT-proBNP levels. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m2 or the presence of proteinuria. Cox proportional hazards models were used to estimate hazard ratios (HRs) for risk of CKD. Linear mixed models were used to compare changes in eGFR. Results During the follow-up period, 800 participants developed CKD. The multivariable-adjusted HRs (95% confidence intervals [CIs]) for developing CKD were 1.00 (reference), 1.32 (1.11–1.57), 1.40 (1.10–1.78), and 1.94 (1.38–2.73) for serum NT-proBNP levels of <55, 55–124, 125–299, and ≥300 pg/ml, respectively (P for trend <0.001). The decline of eGFR during the follow-up was significantly more rapid among participants with higher serum NT-proBNP levels (P for trend <0.001). Adding serum NT-proBNP to the model composed of known risk factors for CKD improved the predictive ability for developing CKD. Conclusions Higher serum NT-proBNP levels were associated with greater risks of developing CKD and greater decline in eGFR. Serum NT-proBNP could be a useful biomarker for assessing the future risk of CKD in a general Japanese population.

Abstract
BACKGROUND Biomarkers for predicting future development of atrial fibrillation (AF) have not been fully established in general populations. The aim of this study was to assess the predictive ability of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) for the development of AF. METHODS AND RESULTS A total of 3126 community-dwelling Japanese subjects aged ≥ 40 years without a history of AF in 2002 were followed up for a median of 10.2 years. Serum NT-proBNP levels at baseline were divided into four categories (≤ 54, 55-124, 125-299, and ≥ 300 pg/mL) according to the current guidelines and prior reports. The hazard ratios for the development of AF were estimated using a Cox proportional hazards model. During the follow-up period, 153 subjects developed new-onset AF. The age- and sex-adjusted cumulative incidence of AF increased significantly with higher serum NT-proBNP levels (p < 0.001 for trend). The association remained significant after adjustment for known risk factors for AF and cardiovascular disease (hazard ratio [95% confidence interval]: ≤ 54 pg/mL: 1.00 [reference]; 55-124 pg/mL: 1.72 [1.00-2.97]; 125-299 pg/mL: 3.95 [2.23-6.98]; ≥ 300 pg/mL: 8.51 [4.48-16.17]; p < 0.001 for trend). Furthermore, incorporation of serum NT-proBNP levels into the model consisting of known risk factors for AF and cardiovascular disease significantly improved the predictive ability for developing AF (Harrell's c-statistics: 0.828 to 0.844, p = 0.01; continuous net reclassification improvement: 0.41, p < 0.001; integrated discrimination improvement: 0.031, p < 0.001). CONCLUSIONS Serum NT-proBNP levels can be a risk biomarker for predicting future development of AF in a general Japanese population.

Abstract
Abstract
Background
Evaluation of two-dimensional (2D) speckle-tracking longitudinal strain (LS) is useful for assessing global and regional left ventricular (LV) dysfunction.
Purpose
The purpose of this study was to test the hypothesis that temporal changes in regional 2D-LS distribution, (i.e., changes in area and intensity of the negative strain), during the systolic period may reflect the LV activation sequence.
Methods
We studied 52 patients with an ejection fraction <35% who were classified into four groups: complete left bundle branch block (LBBB, QRS 162±17 ms, n=17); right ventricular pacing from inferior septum (RVP, QRS 180±29 ms, n=16); left VP from lateral branch of the coronary sinus (LVP, QRS 182±21 ms, n=9); and no conduction block (Narrow QRS, QRS 100±9 ms, n=19). Longitudinal strain was evaluated in three standard apical views, and then bulls-eye distribution maps were constructed every 50 ms from the QRS onset to aortic valve closing (AVC) and at the time of the end of QRS. Segments indicating negative strain at the end of QRS were regarded as an early contraction site. Segments with intensifying negativity of strain as it got closer to the AVC were regarded as a late contraction site.
Results
In patients with LBBB, negative strain appeared initially in the septum region. Then, the contracted area enlarged including the apical region, and the basal lateral region contracted late. On the other hand, Narrow QRS showed a few regional differences in strain at the end of QRS (standard deviation in 17-segments: Narrow QRS 1.3±0.4%*, LBBB 3.3±1.1%, RVP 3.2±1.0%, LVP 3.3±1.1%, *p<0.001), and contracted homogeneously during the systolic period. RVP and LVP showed negative strain at the end of QRS in septum and lateral regions respectively, with the contracted area becoming enlarged towards the opposite regions of the early contracted regions.
Conclusion
The 2D-LS distribution during the systolic period reflects the LV contraction process in patients with an altered ventricular activation sequence, and may have potential for identifying the regions of early activation site and subsequent activation propagation.

Abstract
Extramammary Paget's disease (EMPD) is a rare malignant skin neoplasm characterized by intraepidermal proliferation of tumor cells. The tumor cells of EMPD may sometimes invade into the dermis or metastasize into the regional lymph nodes. Several studies have proposed mechanisms underlying the increased invasiveness of EMPD; however, molecular markers indicating invasiveness have yet to be well characterized. Laminin-5 (Lam-5), a heterotrimer composed of three chains (α3, β3, and γ2), is a major component of the basement membrane in many tissues. One of the chains, Lam-5 γ2, is a marker of invasion, because it often develops as a monomer in malignant neoplasms. We investigated the expression of Lam-5 γ2 and its role for the invasiveness in EMPD. Paraffin-embedded specimens of EMPD obtained from 36 patients were examined immunohistochemically for Lam-5 γ2. The cases adopted into this study comprised 16 cases of intraepidermal lesions and 20 cases with dermal invasion. The basement membrane seen in normal skin disappeared in one-third of non-invasive cases and in most invasive cases. The disappearance of Lam-5 γ2 in the basement membrane and its cytoplasmic expression was more observed in the invasive cases than non-invasive cases. Expression of Lam-5 γ2 may be a biological marker to predict invasiveness of EMPD.
