Abstract
BACKGROUND Infectious aortic disease is a rare and fatal disease, that requires the appropriate intervention. An accurate diagnosis should be promptly established. However, this is difficult because the clinical manifestations of this disease vary and are non-specific. CASE PRESENTATION (CASE 1) An 87-year-old male, presenting with generalized malaise and weight loss, was admitted for further examination. A chest computed tomography (CT) showed mediastinal emphysema. Empirical intravenous antibiotics were administered to address the non-specific infectious findings in the laboratory data. The treatment was effective, and the patient fully recovered. However, he was in shock due to aortic rupture and marked pseudo aneurysmal formation around the aortic arch day 25 of hospitalization. An emergency total aortic arch replacement was performed, and the patient was discharged. (CASE 2) An 82-year-old male who had undergone Y-graft replacement in the abdominal aorta 15 years previously was admitted due to general malaise and anorexia. Abdominal CT revealed emphysematous changes adjacent to the abdominal aorta. The patient responded favorably to empirical treatment with intravenous antibiotics and was discharged 19 days after admission. Four days after discharge, the patient went into cardiac arrest after an episode of hematemesis. Abdominal CT revealed an enlarged stomach and duodenum, filled with massive high-density contents proximal to the abdominal aorta. He died of hemorrhagic shock despite cardiopulmonary resuscitation. CONCLUSIONS Although emphysematous changes are rare, they are red flag signs during the early stage of infectious aortic disease. Thus, physicians should remain vigilant for this kind of critical sign.

Abstract
Tako-tsubo syndrome (TTS) can be triggered by emotional or physical stress and is characterized by transient left ventricular dysfunction with apical ballooning. Some neurologic disorders and pheochromocytoma serve as triggers for TTS, however, its association with primary aldosteronism (PA) is not well known. Pulmonary vein isolation (PVI) with catheter ablation for atrial fibrillation (AF) has been performed worldwide, and TTS following PVI has been reported as a rare complication. Sympathetic stimulation can play an important role in TTS development, however, its mechanism and risk factors are not yet understood.We describe a 72-year-old woman with PA who developed TTS after PVI with radiofrequency catheter ablation (RFCA) for symptomatic paroxysmal AF. Complete isolation of the pulmonary vein was carried out without any complications, however, she complained of epigastric discomfort 7 hours after the procedure. An electrocardiogram showed recurrent AF with a new negative-T wave and prolonged QT interval. Transthoracic echocardiography revealed apical ballooning and basal hypercontraction, characteristic of TTS, and coronary angiography showed no significant stenosis. She was diagnosed with TTS following RFCA for AF and managed well with conservative therapy.The present case suggests that TTS should be recognized as a complication associated with AF ablation. Moreover, PA may be involved in TTS development by increasing sympathetic activity. Further studies on the mechanism and characteristics of TTS are required.

Abstract
BACKGROUND Most patients with chronic limb-threatening ischemia (CLTI) have infrapopliteal arterial disease, which are often challenging to treat. In endovascular treatment (EVT) for these complex lesions, establishing retrograde access is an essential option not only for guidewire crossing but also for device delivery. However, no EVT case has yet been reported requiring inframalleolar thrice distal puncture in a single EVT session so far. CASE PRESENTATION A 60-year-old CLTI patient with grade 3 Wound, Ischemia and foot Infection (WIfI) classification underwent EVT for occluded dorsal artery and posterior tibial artery. First, we conducted successful balloon angioplasty of the posterior tibial artery by establishing a retrograde approach via the lateral plantar artery. To treat the occlusion of the dorsal artery, we punctured the first dorsal metatarsal artery, and retrogradely advanced a guidewire to the dorsal artery occlusion; however, the microcatheter could not follow the guidewire. Therefore, we punctured the occluded distal anterior tibial artery and introduced the retrograde guidewire into the puncture needle. After guidewire externalization, we pulled up the retrograde microcatheter into the occlusion of dorsal artery using the "balloon deployment using forcible manner" technique. Thereafter, we were able to advance the antegrade guidewire into the retrograde microcatheter. After guidewire externalization, an antegrade balloon catheter was delivered and inflated for the purpose of dorsal artery dilation and hemostasis at the "needle rendezvous" point. Consecutively, balloon dilation was performed for puncture site hemostasis of the first dorsal metatarsal artery and complete hemostasis was achieved. Finally, we confirmed good vascular patency and favorable blood flow. After revascularization, transmetatarsal amputation was performed and the wound healed favorably. CONCLUSIONS We can markedly increase the success rate of revascularization by effectively utilizing the retrograde approach in EVT for complex chronic total occlusions in infrapopliteal arterial diseases.

Abstract
Coronary debulking devices are essential in obtaining optimal results in percutaneous coronary intervention (PCI) for severely calcified lesions. However, since the introduction of these devices in Japan, the presence of full-time cardiovascular surgeons in their own facilities has been an essential condition (on-site surgical back-up) as the facility criteria for their use. The criteria were revised in April 2020, making their implementation possible at our hospital. Between May 2020 and January 2022, we administered PCIs using rotational atherectomy (RA) for 33 lesions in 28 patients and orbital atherectomy system (OAS) for 36 lesions in 27 patients. The most preferred strategy in our hospital is OAS via the distal radial approach using a 6Fr Glide sheath or RA via the femoral approach using a 7Fr sheath. The percentages of usable imaging modality as an initial device without lesion modification were 57.1 and 66.7% in the RA and OAS groups, respectively. In the RA procedure, 1.5- and 2.0-mm Rota burrs were more frequently adopted for the initial and second sessions, respectively. In the OAS procedure, the debulking was always initiated at a low speed. Nineteen of the 27 patients underwent additional high-speed debulking. Pre-procedural quantitative coronary angiographic analysis revealed that the minimal lumen diameter was significantly smaller in the RA than in the OAS group. Debulking procedures were successful in all patients excluding two instances of procedure-related complications in the RA group, one of which was coronary perforation safely treated via covered stent deployment without any resulting hemodynamic instability. Our early experience with coronary debulking devices with off-site surgical back-up clearly reveals the safety and feasibility of this procedure in a newcomer facility.

Abstract
BACKGROUND Despite marked progress in endovascular treatment (EVT) techniques and devices, calcified lesions remain one of the toughest obstacles to EVT success. Moreover, because the common femoral artery (CFA) is known as a "non-stenting zone," endovascular strategies for this area are controversial. CASE PRESENTATION Here we describe the technical tips for a novel, less invasive, and effective debulking strategy for severe nodular calcification using an endovascular maneuver. This technique was demonstrated in a 73-year-old man with severe calcified stenosis of the CFA. To complete a stent-less strategy for CFA, we conducted aggressive debulking of the nodular calcification, established a bidirectional approach from the radial artery and the superficial femoral artery (SFA), and inserted a balloon-guiding catheter in the SFA. Under distal protection provided by this catheter, we crushed the nodular calcification 43 times using myocardial biopsy forceps. After achieving a volume reduction of nodular calcification through this maneuver, we completed the procedure by inflating a 6-mm drug-coated balloon catheter. Final angiography demonstrated a reduced filling defect of the contrast medium in the CFA and favorable blood flow as far as the ankle. The puncture site on the SFA was closed with a vascular suture assisted by balloon inflation inside the vessel, which allowed the patient to be ambulatory immediately after the procedure without requiring bed rest. CONCLUSIONS Severely calcified lesions in the CFA are usually difficult to treat using an endovascular strategy, but our novel and less invasive method may become a promising technique for managing these lesions.

Abstract
Depression is an independent risk factor for cardiovascular disease and is significantly associated with the prevalence of abdominal aortic aneurysm (AAA). We investigated the effect of repeated social defeat (RSD) on AAA development. Eight-week-old male wild-type mice were exposed to RSD by being housed with larger CD-1 mice in a shared cage. They were subjected to vigorous physical contact. After the confirmation of depressive-like behavior, calcium chloride was applied to the infrarenal aorta of the mice. At one week, AAA development was comparable between the defeated and control mice, without any differences being observed in the accumulated macrophages or in the matrix metalloproteinase activity. At two weeks, the maximum diameter and circumference of the aneurysm were significantly increased in the defeated mice, and a significant decrease in periaortic fibrosis was also observed. Consistently, the phosphorylation of the extracellular signal-regulated kinase and the incorporation of 5-bromo-2'-deoxyuridine in the primarily cultured aortic vascular smooth muscle cells were significantly reduced in the defeated mice, which was accompanied by a substantial increase in mitogen-activated protein kinase phosphatase-1 (MKP-1). The MKP-1 mRNA and protein expression levels during AAA were much higher in the defeated mice than they were in the control mice. Our findings demonstrate that RSD enhances AAA development by suppressing periaortic fibrosis after an acute inflammatory response and imply novel mechanisms that are associated with depression-related AAA development.

Abstract
Depression is an independent risk factor for cardiovascular disease (CVD). We have previously shown that repeated social defeat (RSD) exaggerates atherosclerosis development by enhancing neutrophil extracellular trap (NET) formation. In this study, we investigated the impact of RSD on arterial thrombosis. Eight-week-old male wild-type mice (C57BL/6J) were exposed to RSD by housing with larger CD-1 mice in a shared home cage. They were subjected to vigorous physical contact daily for 10 consecutive days. After confirming depression-like behaviors, mice underwent FeCl3-induced carotid arterial injury and were analyzed after 3 h. Although the volume of thrombi was comparable between the two groups, fibrin(ogen)-positive areas were significantly increased in defeated mice, in which Ly-6G-positive cells were appreciably co-localized with Cit-H3-positive staining. Treatment with DNase I completely diminished exaggerated fibrin-rich clot formation in defeated mice. Flow cytometric analysis showed that neutrophil CD11b expression before FeCl3 application was significantly higher in defeated mice than in control mice. In vitro NET formation induced by activated platelets was significantly augmented in defeated mice, which was substantially inhibited by anti-CD11b antibody treatment. Our findings demonstrate that RSD enhances fibrin-rich clot formation after arterial injury by enhancing NET formation, suggesting that NET can be a new therapeutic target in depression-related CVD.

Abstract
Abstract
Background
Takotsubo syndrome (TTS), also known as stress cardiomyopathy or apical ballooning syndrome, presents as reversible regional left ventricular wall motion abnormalities in the absence of obstructive coronary artery disease. It is associated with a recurrence rate of approximately 4%. However, multiple recurrence episodes are rare in clinical settings, and the predictors of recurrence and preventive methods have yet to be fully elucidated.
Case summary
A 69-year-old woman experienced two TTS episodes before complaining of sudden-onset epigastric pain without any particular trigger. No significant coronary lesion was observed on coronary angiography, while left ventriculography showed the typical findings of apical ballooning and a hyperkinetic wall motion at the basal level of the left ventricle. The patient was again diagnosed with recurrent TTS. On Day 5 of hospitalization, follow-up echocardiography showed mural thrombus formation in the left ventricular apex. Anticoagulant therapy with oral warfarin following intravenous heparin was effective in dissolving the thrombus. She was safely discharged on Day 16 of hospitalization. However, two additional recurrent TTS episodes provoked by emotional stress occurred afterwards. Since the final hospitalization, she has been prescribed perindopril 4 mg/day and β1-receptor-selective β-blocker bisoprolol 5 mg/day and has been able to avoid the 6th recurrence of TTS for more than 12 months at present.
Conclusion
Multiple recurrent TTS episodes are rare in the clinical setting. As such, the long-term follow-up of this case may provide clues on the pathophysiology of this disease and aid us in establishing effective preventive strategies.

Abstract
BACKGROUND In practical settings of endovascular treatment (EVT) for below-the-knee arteries, we often encounter cases of severe calcification. To overcome problems regarding device uncrossing due to severe calcifications, a bidirectional approach and subsequent guidewire externalization is one of critical methods. CASE REPORT A 74-year-old female with refractory skin ulcers on the lower frontal thigh and necrotic toes on the left side showed occlusion in both the anterior tibial artery (ATA) and tibio-peroneal trunk. Both occluded vessels were accompanied with dense calcification. In the process of EVT targeting the occluded ATA, the retrograde guidewire successfully passed the occlusion and was advanced into the antegrade guide sheath. Next, we attempted guidewire externalization, but severe calcification of the ATA hampered the procedure. Therefore, we introduced a guide extension catheter and a balloon catheter in an antegrade fashion to establish a system of trapping the retrograde guidewire between these devices. Then, we pulled the system back outside the guide sheath, which completed guidewire externalization. We performed prolonged balloon dilatation and finally achieved favorable revascularization of the ATA. CONCLUSIONS Our novel method led to successful retrograde guidewire externalization, overcoming severely calcified lesions. It is generally essential for clinicians to increase their expertise regarding EVT procedures to attain better outcomes.

Abstract
Background Although timely coronary intervention can result in markedly improved clinical outcomes of patients with acute coronary syndrome (ACS), non-ST-elevation (NSTE)-ACS is sometimes difficult to accurately diagnose. Case presentation A 52-year-old woman complained of acute chest pain with sudden onset. Both electrocardiography (ECG) and echocardiography showed normal results, and we urgently needed to make a differential diagnosis among critical illnesses such as acute coronary syndrome and nonischemic cardiovascular life-threatening diseases. Contrast-enhanced computed tomography (CT) without ECG synchronization showed evidence of neither aortic dissection nor pulmonary embolism, but regionally reduced contrast enhancement in the posterior myocardium, which were suggestive of myocardial ischemia. Emergency coronary angiography demonstrated severe stenosis of the left circumflex artery, and we achieved favorable revascularization with drug-eluting stent deployment. Conclusions We diagnosed a patient with NSTE-ACS in whom contrast-enhanced CT without ECG synchronization was effective for visualization of reduced myocardial perfusion, suggesting ischemic heart disease.

Abstract
Social stress (SS) has been linked to the development of cardiovascular disease (CVD), which is closely associated with insulin resistance (IR); however, the causal effect of SS on IR remains unclear. The 8-week-old male C57BL/6 mice were exposed to SS by housing with a larger CD-1 mouse in a shared home cage without physical contact for 10 consecutive days followed by high-fat diet (HFD) feeding. Control mice were housed in the same cage without a CD-1 mouse. After 6 weeks of HFD, insulin sensitivity was significantly impaired in stressed mice. While the percentage of classically activated macrophages in epididymal white adipose tissue (eWAT) was equivalent between the two groups, the percentage of lymphocyte antigen 6 complex locus G6D (Ly-6G)/neutrophil elastase (NE)-double positive cells markedly increased in stressed mice, accompanied by augmented NE activity assessed by ex vivo eWAT fluorescent imaging. Treatment with an NE inhibitor completely abrogated the insulin sensitivity impairment of stressed mice. In vitro NE release upon stimulation with a formyl peptide receptor 1 agonist was significantly higher in bone marrow neutrophils of stressed mice. Our findings show that SS-exposed mice are susceptible to the development of HFD-induced IR accompanied by augmented NE activity. Modulation of neutrophil function may represent a potential therapeutic target for SS-associated IR.

Abstract
Objective Maternal high-fat diet (HFD) has been shown to promote the development of insulin resistance (IR) in adult offspring; however, the underlying mechanisms remain unclear. Methods Eight-week-old female wild-type mice (C57BL/6) were fed either an HFD or a normal diet (ND), one week prior to mating, and the diet was continued throughout gestation and lactation. Eight-week-old male offspring of both groups were fed an HFD for 8 weeks. Results Offspring of HFD-fed dams (O-HFD) exhibited significantly impaired insulin sensitivity compared with the offspring of ND-fed dams (O-ND). The adipocyte size of the eWAT increased significantly in O-HFD and was accompanied by abundant crown-like structures (CLSs), as well as a higher concentration of interleukin 1β (IL-1β) in the eWAT. Treatment with an inflammasome inhibitor, MCC950, completely abrogated the enhanced IR in O-HFD. However, ex vivo caspase-1 activity in eWAT revealed no difference between the two groups. In contrast, noncanonical inflammasome activation of caspase-11 was significantly augmented in O-HFD compared with O-ND, suggesting that membrane pore formation, but not cleavage of pro-IL-1β by caspase-1, is augmented in O-HFD. To examine the membrane pore formation, we performed metabolic activation of bone marrow-derived macrophages (BMDMs). The percentage of pore formation assessed by ethidium bromide staining was significantly higher in BMDMs of O-HFD, accompanied by an enhanced active caspase-11 expression. Consistently, the concentration of IL-1β in culture supernatants was significantly higher in the BMDMs from O-HFD than those from O-ND. Conclusions These findings demonstrate that maternal HFD exaggerates diet-induced IR in adult offspring by enhancing noncanonical caspase-11-mediated inflammasome activation. Maternal HFD increases the vulnerability to HFD-induced IR in adult offspring. Maternal HFD augments inflammasome activation in eWAT in adult offspring. Treatment with an inflammasome inhibitor abrogates IR in offspring of HFD-fed dam. Maternal HFD augments the noncanonical inflammasome activation pathway of caspase-11. Maternal HFD augments IL-1β release from BMDMs by enhancing membrane pore formation.

This reaction is induced by neutron irradiation of the 3He fraction contained in natural isotopic abundance liquid helium with neutron beams either from the Japan Proton Accelerator Research Complex, Materials and Life Science Experimental Facility (JPARC)/Materials and Life Science Experimental Facility or from the Kyoto University Institute for Integrated Radiation and Nuclear Science. These 4He2 * clusters are expected to be ideal tracers of the normal-fluid component in superfluid helium with several advantageous properties. Evidence of the excimer generation is inferred by detection of laser induced fluorescence emitted from the 4He2 * clusters excited by a purpose-built short pulse gain-switched titanium:sapphire (Ti:sa) laser operating at a wavelength of 905 nm. The setup and performance characteristics of the laser system including the Ti:sa and two continuous wave re-pumping lasers are described. Detection at the fluorescence wavelength of 640 nm is performed by using optical bandpass filtered photomultiplier tubes (PMT). Electrical noise in the PMT acquisition traces could successfully be suppressed by post-processing with a simple algorithm. Despite other laser-related backgrounds, the excimer was clearly identified by its fluorescence decay characteristics. Production of the excimer was found to be proportional to the neutron flux, adjusted via insertion of different collimators into the neutron beam. These observations suggest that the apparatus we constructed does function in the expected manner and, therefore, has the potential for groundbreaking turbulence research with superfluid helium.

Abstract
BACKGROUND Oesophageal squamous cell carcinoma is an aggressive disease owing to early and widespread lymph node metastases. Multimodal therapy and radical surgery may improve prognosis. Few studies have investigated the efficacy of radical lymph node and thoracic duct resection. METHODS Patients with oesophageal squamous cell carcinoma who underwent transthoracic minimally invasive oesophagectomy (TMIE) for cancer at Keio University Hospital between January 2004 and December 2016 were selected. Between 2004 and 2008, TMIE was performed in the lateral decubitus position without thoracic duct resection (standard TMIE). From 2009 onwards, TMIE with extended lymph node and thoracic duct resection was introduced (extended TMIE). Demographics, co-morbidity, number of retrieved lymph nodes, pathology, postoperative complications and recurrence-free survival (RFS) were compared between groups. RESULTS Forty-four patients underwent standard TMIE and 191 extended TMIE. There were no significant differences in clinical and pathological tumour stage or postoperative complications. The extended-TMIE group had more lymph nodes removed at nodal stations 106recL and 112. Among patients with cT1 N0 disease, RFS was better in the extended-TMIE group (P < 0·001), whereas there was no difference in RFS between groups in patients with advanced disease. CONCLUSION Extended TMIE including thoracic duct resection increased the number of lymph nodes retrieved and was associated with improved survival in patients with cT1 N0 oesophageal squamous cell carcinoma.

Abstract
Recently, there have been increasing opportunities to treat patients with peripheral arterial disease. Of those patients, both pathological conditions, such as acute limb ischemia (ALI) and chronic critical limb ischemia (CLI), are closely associated with high risks of major amputation, disability and death. We encountered a very rare case of CLI subsequent to ALI. An 83-year-old male showed the sudden onset of ALI, probably due to thromboembolism from an abdominal aortic aneurysm during an operation for gastric cancer. The patient was referred to another hospital for Fogarty thrombectomy. About 1 month after ALI onset, necrosis of the left first toe gradually progressed. On angiography of the left lower limb, we noted occlusions of both anterior and posterior tibial arteries. Then, we successfully conducted balloon angioplasty for the below-the-knee arteries. Thereby, favorable blood flow was achieved, which led to successful wound healing without amputations.

Abstract
Abstract
Background and objective
Maternal high-fat diet (HFD) has been shown to modulate vascular function and remodeling in adult offspring. Here, we investigated the impact of maternal HFD on abdominal aortic aneurysm (AAA) formation.
Methods and results
Eight-week-old female wild-type mice (C57BL/6) were fed a HFD or normal diet (ND) one week prior to mating and received during pregnancy and lactation. In eight-week-old offspring of both genders, AAA was induced with the application of 0.5M calcium chloride (CaCl2) on the infrarenal aorta. Male offspring of HFD-fed dams (O-HFD) showed a significant increase in maximum outer diameter of AAA at 1, 4 and 8 weeks after surgery compared with offspring of ND-fed dams (O-ND) (P<0.05). The lengths of outer circumference assessed by histological analysis were increased in O-HFD (P<0.05). Likewise, female O-HFD showed a greater length of outer circumference than female O-ND (P<0.05). While the number of F4/80-positive cells at 1 wk after surgery was comparable between the male O-HFD and O-ND, the percentage of MMP-9/F4/80 double-positive cells was significantly increased in male O-HFD. Consistently, fluorescent image of abdominal aorta taken by IVIS at 1 wk after surgery revealed a 2-fold increase in MMP activity (P<0.01). Intriguingly, F4/80-positive cells in male O-HFD showed a 2.5-fold increase in co-staining with tartrate-resistant acid phosphate (TRAP), typical marker of osteoclast-like macrophages which abundantly secrete proteases than classically activated macrophages (M1), while the percentage of TNF-α/F4/80 double-positive cells was comparable between the 2 groups. Pharmacological inhibition of osteoclastogenesis by zoledronic acid (ZA) (100μg/kg) completely abolished the exaggerated AAA development in male O-HFD to a similar extent of that in male O-ND, while AAA development in male O-ND mice did not change even after ZA treatment. Furthermore, in vitro TNF-α-induced osteoclast differentiation of bone marrow-derived macrophages (BMDMs) showed a significantly higher number of TRAP-positive cells, accompanied by increased calcitonin receptor mRNA expression. Western blotting analysis showed that protein expression level of NFATc1, master regulator of osteoclastogenesis, was significantly higher in BMDM of O-HFD than O-ND.
Conclusion
Our findings demonstrate that maternal HFD accelerates CaCl2-induced AAA expansion, accompanied by the exaggerated accumulation of osteoclast-like macrophages and augmented activity of MMPs. Inhibition of macrophages skewing toward osteoclast-like cells could be a potential therapeutic target for preventing AAA development.

Abstract
Background and objective
Depression is an independent risk factor of cardiovascular disease (CVD). We have recently shown that repeated social defeat (RSD) precipitates depressive-like behaviorsin apoE−/− mice and exaggerates atherosclerosis development by enhancing neutrophil extracellular traps (NETs) formation (BBRC 2018; 500:490). Here, we investigated the impact of RSD on arterial thrombosis.
Methods and results
Eight-week-old male WT mice were exposed to RSDby housing with a larger CD-1 mouse in a shared home cage. They were subjected to vigorous physical contact daily for 10 consecutive days. Control mice were housed in the same gage without physical contact. After social interaction testto confirm depressive-like behaviors, defeated mice (19 of 31) and control mice (12 of 14) were underwent arterial injury at 10 wks of age. A filter paper saturated with 10% FeCl3was applied on the adventitial surface of left carotid artery for 3 min and analyzed 3 hrs later. The volume of thrombi calculated by summing8–15 frozen cross-sectional images, each separated by 200 μm, was comparable between the 2 groups. However, fibrinogen/fibrin-positive areas in immunofluorescent images were significantly increased in defeated mice (27.8% vs. 48.8%, Control vs. Defeat, P<0.01).The numberof Ly-6G-positive cells in thrombi was markedly higher in defeated mice (144/mm2 vs. 878/mm2, Control vs. Defeat, P<0.05). Further, Ly-6G-positive cells were almost accumulated at the inner surface of injured artery, which were co-localized with neutrophil elastase, Cit-H3, and CD41-positive staining. Treatment with DNase Icompletely diminished the exaggerated fibrin-rich clot formation in defeated miceto a similar extent of control mice (25.7% vs. 22.3%, Control vs. Defeat, P= NS), while the volume of thrombi and number of Ly-6G-positive cells in thrombi were comparable between the 2 groups even afterDNase I treatment. Platelet aggregations induced by ADP or collagen were comparable between the 2 groups, suggesting that NETs formation primarily contributes to the exaggerated fibrin-rich clot formation in defeated mice.
Conclusions
Our findings demonstrate for the first time that repeated social defeat enhances fibrin-rich clot formation after arterial injury by enhancing NETs formation, suggesting that NETosis could be a new therapeutic target in depression-related CVD development.

Abstract
Abstract
Background
Maternal high-fat diet (HFD) has been shown to promote the development of insulin resistance (IR) in adult offspring; however, the underlying mechanisms remain unclear.
Approach and results
Eight-week-old female wild-type mice (C57BL/6) were fed a HFD or normal diet (ND) one week prior to mating, and received during pregnancy and lactation. Eight-week-old male offspring of both groups were fed a HFD for 8 weeks. Offspring of HFD-fed dams (O-HFD) showed significantly enhanced IR compared with offspring of ND-fed dams (O-ND). There was no difference in body weight, epidydimal white adipose tissue (eWAT) weight, and cumulative caloric intake between the 2 groups. However, eWAT adipocyte size was significantly increased in O-HFD, accompanied by the abundant crown-like structures. Flow cytometric analysis revealed an increased percentage of M1, but not M2, macrophages. Serum and eWAT concentrations of IL-1β, but not TNF-α, were significantly higher in O-HFD than O-ND (3.7-fold and 2.0-fold, respectively, P<0.05). Treatment with NLRP3 inflammasome inhibitor MCC950 completely abrogated the enhanced IR in O-HFD to a similar extent of that in O-ND, although IR was modestly, but not significantly, ameliorated in O-ND even after MCC950 treatment. Consistent with in vivo findings, in vitro polarization of bone marrow-derived macrophages (BMDMs) did not show any difference in TNF-α mRNA expression after conventional stimulation. In contrast, palmitate acid (PA)-mediated metabolic activation of BMDMs following LPS priming showed a significantly higher concentration of IL-1β in culture supernatants from O-HFD (45%, P<0.05). However, protein expression levels of NLRP-3, ASC, and procaspase-1 after LPS priming were equivalent between the 2 groups. Consistently, intracellular flow cytometric analysis of caspase-1 activity after PA activation did not show any difference, which was compatible with the finding that ex vivo caspase-1 activity of eWAT assessed by fluorescent image of IVIS revealed no difference between the 2 groups. To further examine the mechanism of augmented IL-1β release in BMDM of O-HFD, we examined the cleavage of caspase substrate gasdermin D (GSDMD) and subsequent pore formation. Protein and gene expression levels of GSDM-D after LPS priming were significantly higher in O-HFD (50% and 381%, respectively, P<0.05). At 2 hrs after PA stimulation following LPS priming, cleaved GSDM-D was significantly increased in O-HFD (80%, P<0.01). Consistently, percentage of pore formation assessed by ethidium bromide staining was significantly higher in O-HFD (60%, P<0.05), while LDH release could not be observed.
Conclusions
Our findings demonstrate that maternal HFD exaggerates diet-induced insulin resistance in adult offspring by enhancing pyroptosis through augmented GSDM-D-mediated pore formation.

Abstract
Nivolumab, an anti-PD-1 antibody, is now considered an important therapeutic agent in several advanced malignancies. However, immune-related adverse events such as endocrinopathies have been reported with its use. Thyroid disorder and isolated adrenocorticotropic hormone deficiency have frequently been reported as nivolumab-induced immune-related adverse events. Another endocrinopathy is nivolumab-induced type 1 diabetes mellitus (t1dm), described as diabetes mellitus with rapid onset and complete insulin insufficiency, at times leading to fulminant t1dm. We report the case of a 68-year-old woman who developed pancreatic islet-related autoantibody-negative t1dm, possibly induced by nivolumab, under continuous glucocorticoid administration. She was treated with nivolumab for advanced malignant melanoma, concomitant with 10 mg prednisolone daily for thrombophlebitis tapered to 5 mg after 13 courses of nivolumab therapy. At approximately the 27th course of nivolumab therapy, she showed elevated plasma glucose levels despite preserved insulin secretion. A month later, she developed diabetic ketoacidosis. Her insulin secretion decreased and finally was exhausted. She was diagnosed with acute-onset rather than fulminant t1dm because of a rapidly progressive course to diabetic ketoacidosis during just more than 1 week. She is currently receiving insulin replacement. There has been no recurrence of the melanoma. Thus, nivolumab might induce autoimmune diabetes mellitus, with patients having t1dm-sensitive human leucocyte antigen being more susceptible even when receiving glucocorticoids. Physicians should be aware that nivolumab could potentially induce t1dm as a critical immune-related adverse event.

Abstract
PURPOSE: We evaluated the feasibility and safety of the reverse catheterization technique of the superficial femoral artery (ReCAT) for single-stage endovascular treatment (EVT) in patients with bilateral infrainguinal diseases. MATERIALS AND METHODS: We retrospectively evaluated 24 consecutive patients (overall median age: 79 years; male patients: 21 [87.5%]) who underwent EVT for bilateral infrainguinal diseases. The objective of ReCAT was to perform single-stage EVT in patients with bilateral infrainguinal diseases with a one-time unilateral femoral artery puncture. The main outcomes were the incidence of puncture site complications, including major bleeding or hematoma requiring transfusion, pseudoaneurysm, and arteriovenous fistula, and ReCAT procedure-related arterial dissection or perforation, which were assessed by ultrasonography on the day after the procedure. The secondary outcome measures were in-hospital mortality and in-hospital amputation. RESULTS: Reverse catheterization technique of the superficial femoral artery was successful in 23 (95.8%) of the 24 patients; it failed in 1 patient due to severe calcification and a previously implanted stent in the ipsilateral iliac artery. The median operation time, radiation time, and the volume of contrast media used were 108 (84-142) minutes, 37 (27-55) minutes, and 111 (80-157) mL, respectively. There were no incidences of puncture site complications and arterial dissection related to the ReCAT procedure. One case of vessel perforation in a branch of the ipsilateral superficial femoral artery occurred due to flipped guidewire injury. CONCLUSION: Reverse catheterization technique of the superficial femoral artery is safe and effective in performing single-stage EVT for bilateral infrainguinal diseases. It might also reduce the number of EVTs and complications due to multiple femoral artery punctures.

Abstract
Recurrent laryngeal nerve paralysis (RLNP) is a frequent and serious complication following esophageal cancer surgery. Therefore, this study aims to evaluate the correlation between recurrent laryngeal nerve (RLN) size and RLNP. This was a retrospective study of esophageal cancer patients who underwent thoracoscopic esophagectomy from January 2012 to December 2014. Eighty-four patients were included in the primary analysis. Diameter of the RLN was measured using the digital video recording of surgical procedures by the ratio between scissor and RLN. For evaluation of vocal cord paralysis or paresis, indirect laryngoscopy was performed. Because RLNP more frequently occurs on the left side than the right, we evaluated the correlation between size of the left RLN and left RLNP. The median size of the left RLN was 1.51 mm. We found that the incidence of postoperative left RLNP (Clavien-Dindo classification ≥1) was significantly higher (71% vs. 24%; P < 0.001) in thin RLNs (≤1.5 mm) than in thick RLNs (>1.5 mm). Thin RLN (P < 0.001), female sex (P = 0.025), and being overweight (P = 0.034) were identified as significant independent risk factors for postoperative RLNP. RLNP more easily occurred when the RLN was thin. It is difficult to confirm occurrence of postoperative RLNP before and at extubation. Therefore, it is helpful to know its risk factors including size of RLN.

Abstract
Depression is an independent risk factor of cardiovascular disease (CVD); however, the causal association remains undefined. We exposed mice to repeated social defeat (RSD) to precipitate depressive-like behaviors, and investigated the effects on atherosclerosis. Eight-week-old male apoE-/- mice were exposed to RSD by housing with a larger CD-1 mouse in a shared home cage. They were subjected to vigorous physical contact daily for 10 consecutive days and fed a high-cholesterol diet (HCD) for 6 weeks. The social interaction ratio and immobility time showed dramatic social avoidance before and after HCD feeding. Defeated mice showed higher increase in atherosclerotic lesion areas in the aortic root and entire aorta than control mice. Mean blood pressure and lipid profile were equivalent in both groups. While Ly-6G- and Mac3-positive areas in the aortic root were comparable between the groups, citrullinated histone H3 (Cit-H3)- and myeloperoxidase (MPO)-positive areas, markers of neutrophil extracellular traps (NETs), were significantly increased in the defeated mice. Treatment with DNase I completely diminished the exaggerated atherosclerosis. The proportion of peripheral blood polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC), but not of inflammatory monocytes, was markedly increased. Moreover, in vitro NETs formation from bone marrow (BM) PMN-MDSC was markedly augmented, accompanied by higher expression of Nox2 gene and reactive oxygen species. Our findings demonstrate that exposure to RSD promotes atherosclerosis by augmenting NETs formation within the plaque. This provides new insight into the underlying mechanism of depression-related CVD.

Abstract
Background Oesophagectomy has a high risk of postoperative morbidity. The impact of postoperative complications on overall survival of oesophageal cancer remains unclear. This meta‐analysis addressed the impact of complications on long‐term survival following oesophagectomy. Methods A search of PubMed and Cochrane Library databases was undertaken for systematic review of papers published between January 1995 and August 2016 that analysed the relation between postoperative complications and long‐term survival. In the meta‐analysis, data were pooled. The main outcome was overall survival (OS). Secondary endpoints included disease‐free (DFS) and cancer‐specific (CSS) survival. Results A total of 357 citations was reviewed; 21 studies comprising 11 368 patients were included in the analyses. Overall, postoperative complications were associated with significantly decreased 5‐year OS (hazard ratio (HR) 1·16, 95 per cent c.i. 1·06 to 1·26; P = 0·001) and 5‐year CSS (HR 1·27, 1·09 to 1·47; P = 0·002). Pulmonary complications were associated with decreased 5‐year OS (HR 1·37, 1·16 to 1·62; P < 0·001), CSS (HR 1·60, 1·35 to 1·89; P < 0·001) and 5‐year DFS (HR 1·16, 1·00 to 1·33; P = 0·05). Patients with anastomotic leakage had significantly decreased 5‐year OS (HR 1·20, 1·10 to 1·30; P < 0·001), 5‐year CSS (HR 1·81, 1·11 to 2·95; P = 0·02) and 5‐year DFS (HR 1·13, 1·02 to 1·25; P = 0·01). Conclusion Postoperative complications after oesophagectomy, including pulmonary complications and anastomotic leakage, decreased long‐term survival.

Abstract
Although no consensus is available on the treatment of esophageal squamous cell carcinoma (ESCC) invading adjacent organs (T4), establishing effective induction treatments is crucial to altering an unresectable status and achieving curative resection. Here, we evaluated the efficacy of chemotherapy using 5-fluorouracil, cisplatin, and docetaxel (DCF) as the initial induction treatment for T4 ESCC. Fifty patients without distant metastasis who underwent initial induction chemotherapy using DCF for T4 ESCC were propensity score-matched with 50 patients who underwent radiotherapy concurrent with cisplatin and 5-fluorouracil (CRT). In the DCF group, 24 (48.0%) patients underwent surgery, achieving a 64% clinical response rate compared to 72.0% for induction CRT. CRT was also performed in another 24 (48.0%) patients in the DCF group in whom surgical resection was not indicated. The DCF group had significantly higher overall resectability than the CRT group (78.0% vs. 48.0%, P = 0.0017). The esophageal perforation rate during induction treatments was significantly lower in the DCF group than the CRT group (4.0% vs. 18.0%, P = 0.0205). Prognosis was significantly better in the DCF group than the CRT group (5-year cancer-specific survival 42.1% vs. 22.2%, P = 0.0146). Thus, induction DCF chemotherapy in patients with T4 ESCC reduced esophageal perforation and increased overall resectability, leading to better survival than CRT alone. Therefore, DCF chemotherapy may be an effective and safe option for initial induction treatment of T4 ESCC.

Abstract
Abstract
[Background] Axilla surgery in node-positive breast cancer is dramatically changing from axillary lymph node dissection (ALND) to sentinel node biopsy (SNB). From the results of ACOSOG Z0011, IBCSG23-01 and AMAROS trials, adjuvant therapy and regional node irradiation could reduce regional lymph node recurrence for sentinel node-positive breast cancer patients. However, optimal indication of SNB alone remains uncertain. Trial design: To evaluate the outcome of sentinel node-positive breast cancer patients, the Japanese Society for Sentinel Node Navigation Surgery (SNNS) conducted a prospective cohort study in 2013 (UMIN000011782, Jpn J Clin Oncol, p.876-9, 2014). [Eligibility criteria] For eligible patients, SNB was performed or scheduled after 1 January 2012. Then 1 to 3 positive micrometastases or macrometastases in sentinel lymph nodes are confirmed by histological or molecular diagnosis. Primary chemotherapy before or after SNB is also acceptable for registration. [Specific aims] The primary endpoint is the 5-year recurrence rate of regional lymph node in patients treated with SNB alone. The secondary endpoint is the 5-year overall survival rate of this cohort. Patients treated with SNB followed by ALND are also registered simultaneously to compare the prognosis. The propensity score matching (PSM) is used to make the distributions of baseline risk factors comparable. [Statistical method] Based on an estimated recurrence rate of 5% at 5 years among patients treated with SNB alone, 240 patients are needed to give a 80% power to reject the null hypothesis that the recurrence rate is 10% with a one-sided type I error rate of 2.5%. If we consider that some patients will be lost to follow-up or become ineligible, a total of 250 patients will be needed to comprise the sample. [Present accrual] Eight hundred and eighty patients who underwent SNB alone or SNB followed by ALND were registered from 27 participating institutes between 2013 and 2016. Data cleaning is being performed. Patient's background and PSM will be reported.

Abstract
INTRODUCTION Lymphoid tissue fibrosis may contribute to incomplete immune reconstitution on antiretroviral therapy (ART) via local CD4+ T lymphocyte (CD4) depletion. Hyaluronic acid (HA) increases with fibrotic burden. CXCL4 concentrations increase in response to pro-fibrotic stimuli, but lower CXCL4 concentrations in HIV-infected individuals may reflect successful immune evasion by HIV. We investigated relationships between circulating HA and CXCL4 concentrations and immune reconstitution on ART in HIV-infected Multicenter AIDS Cohort Study participants. METHODS HIV-infected men on ART for >1 year with cryopreserved plasma samples and suppressed post-ART HIV-1 RNA were included. Men with post-ART CD4 <200 cells/mm3 were defined as immunologic non-responders (n = 25). Age-/race-matched men with post-ART CD4 >500 cells/mm3 served as controls (n = 49). HA and CXCL4 concentrations were measured via ELISA. RESULTS Median pre-ART CD4 was 297 cells/mm3 for non-responders vs 386 cells/mm3 for controls. Median post-ART CD4 was 141 cells/mm3 for non-responders and 815 cells/mm3 for controls. HIV infection duration was 23 years, with median time on ART 13 years for non-responders vs 11 years for controls. Pre-ART HA and CXCL4 concentrations did not vary by eventual immune reconstitution status. Post-ART HA concentrations tended to be higher (85 vs 36 ng/mL, p = 0.07) and CXCL4 concentrations were lower (563 vs 1459 ng/mL, p = 0.01) among non-responders. Among men with paired pre-/post-ART samples, non-responders had greater HA increases and CXCL4 decreases than controls (HA: 50 vs 12 ng/mL, p = 0.04; CXCL4: -1258 vs -405 ng/mL, p = 0.01). CONCLUSIONS Higher circulating concentrations of HA and lower concentrations of CXCL4 are associated with failure of immune reconstitution on ART.

Abstract
BACKGROUND AND OBJECTIVE Human periodontal ligament cells (HPDLCs) express transforming growth factor-β1 (TGF-β1) that regulates differentiation and proliferation, and plays key roles in homeostasis of PDL tissue. Transgelin is a cytoskeleton-associated protein with an Smad-binding element in its gene promoter region. In this study, we examined the localization and potential function of transgelin in PDL tissue and cells. MATERIAL AND METHODS Microarray analysis of HPDLC lines (2-14, 2-23 and 2-52) was performed. Expression of transgelin in HPDLCs was examined by quantitative reverse transcription-polymerase chain reaction, immunofluorescence staining and western blot analysis. Effects of TGF-β1 and its signaling inhibitor, SB431542, on transgelin expression in HPDLCs were examined by western blot analysis. The effects of transgelin knockdown by small interfering RNA (siRNA) on HPDLC proliferation stimulated by TGF-β1 were assessed by WST-1 assay. RESULTS In microarray and quantitative reverse transcription-polymerase chain reaction analyses, the expression levels of transgelin (TAGLN) in 2-14 and 2-23 cells, which highly expressed PDL markers such as periostin (POSTN), tissue non-specific alkaline phosphatase (ALPL), α-smooth muscle actin (ACTA2) and type I collagen A1 (COL1A1), was significantly higher than those in 2-52 cells that expressed PDL markers weakly. Immunohistochemical and immunofluorescence staining revealed expression of transgelin in rat PDL tissue and HPDLCs. In HPDLCs, TGF-β1 treatment upregulated transgelin expression, whereas inhibition of the type 1 TGF-β1 receptor by SB431542 suppressed this upregulation. Furthermore, TAGLN siRNA transfection did not promote the proliferation of HPDLCs treated with TGF-β1. The expression levels of CCNA2 and CCNE1, which regulate DNA synthesis and mitosis through the cell cycle, were also not upregulated in HPDLCs transfected with TAGLN siRNA. CONCLUSION Transgelin is expressed in PDL tissue and might have a role in HPDLC proliferation induced by TGF-β1 stimulation.

Abstract
In cases of pulp exposure due to deep dental caries or severe traumatic injuries, existing pulp-capping materials have a limited ability to reconstruct dentin-pulp complexes and can result in pulpectomy because of their low potentials to accelerate dental pulp cell activities, such as migration, proliferation, and differentiation. Therefore, the development of more effective therapeutic agents has been anticipated for direct pulp capping. Dental pulp tissues are enriched with dental pulp stem cells (DPSCs). Here, the authors investigated the effects of semaphorin 3A (Sema3A) on various functions of human DPSCs in vitro and reparative dentin formation in vivo in a rat dental pulp exposure model. Immunofluorescence staining revealed expression of Sema3A and its receptor Nrp1 (neuropilin 1) in rat dental pulp tissue and human DPSC clones. Sema3A induced cell migration, chemotaxis, proliferation, and odontoblastic differentiation of DPSC clones. In addition, Sema3A treatment of DPSC clones increased β-catenin nuclear accumulation, upregulated expression of the FARP2 gene (FERM, RhoGEF, and pleckstrin domain protein 2), and activated Rac1 in DPSC clones. Furthermore, in the rat dental pulp exposure model, Sema3A promoted reparative dentin formation with dentin tubules and a well-aligned odontoblast-like cell layer at the dental pulp exposure site and with novel reparative dentin almost completely covering pulp tissue at 4 wk after direct pulp capping. These findings suggest that Sema3A could play an important role in dentin regeneration via canonical Wnt/β-catenin signaling. Sema3A might be an alternative agent for direct pulp capping, which requires further study.

Abstract
BACKGROUND AND OBJECTIVE Cigarette smoking has detrimental effects on periodontal tissue, and is known to be a risk factor for periodontal disease, including the loss of alveolar bone and ligament tissue. However, the direct effects of cigarette smoking on periodontal tissue remain unclear. Recently, we demonstrated that benzo[a]pyrene (BaP), which is a prototypic member of polycyclic aryl hydrocarbons and forms part of the content of cigarettes, attenuated the expression of extracellular matrix remodeling-related genes in human periodontal ligament (PDL) cells (HPDLCs). Thus, we aimed to examine the effects of BaP on the osteoblastic differentiation and collagen synthesis of HPDLCs. MATERIAL AND METHODS HPDLCs were obtained from healthy molars of three patients, and quantitative reverse transcription-polymerase chain reaction were performed for gene expression analyses of cytochrome P450 1A1 and 1B1, alkaline phosphatase, bone sialoprotein and aryl hydrocarbon receptor (AhR), a receptor for polycyclic aryl hydrocarbons. We have also analyzed the role of the AhR, using 2-methyl-2H-pyrazole-3-carboxylic acid (2-methyl-4-o-tolylazo-phenyl)-amide (CH-223191), which is an AhR antagonist. RESULTS The treatment of HPDLCs with BaP reduced mRNA expression of osteogenic genes, alkaline phosphatase activity, mineralization and collagen synthesis. The treatment with CH-223191 subsequently restored the observed suppressive effects of BaP on HPDLCs. CONCLUSIONS The present results suggest that BaP exerts inhibitory effects on the maintenance of homeostasis in HPDL tissue, such as osteoblastic differentiation and collagen synthesis of HPDLCs, and that this signaling pathway could be suppressed by preventing the transactivity of AhR. Future studies may unveil a role for the inhibition of AhR as a promising therapeutic agent for periodontal disease caused by cigarette smoking.

Abstract
OBJECTIVE To investigate time intervals of the ductus venosus (DV) flow velocity waveform (FVW) and those of the cardiac cycle that correspond with each DV-FVW component in fetuses with intrauterine growth restriction (IUGR) due to placental insufficiency. METHODS Women with a pregnancy complicated by IUGR were recruited into the study, as was a normal control group. Time intervals for systolic (S) and diastolic (D) components were measured in DV-FVW as follows: S(DV), from the nadir of the a-wave during atrial contraction to the nadir between the S-wave and D-wave; D(DV), from the nadir between S-wave and D-wave to the nadir of the a-wave. Regarding cardiac cycles, the following variables were measured from ventricular inflow through the tricuspid valve (TV) and mitral valve (MV): S(TV) and S(MV), from the second peak of ventricular inflow caused by atrial contraction (A-wave) to the opening of the atrioventricular valve; D(TV) and D(MV), from the opening of the atrioventricular valve to the peak of the A-wave. In the IUGR group, only the last examination performed within 1 week of delivery was used for analysis. All variables were analyzed statistically using Z-scores. RESULTS Data were obtained from 249 normal fetuses and 26 fetuses with IUGR. Compared to normal fetuses, S(DV) showed a significant decrease (P < 0.001), while D(DV) showed a significant increase (P < 0.001) in the IUGR group. Regarding cardiac cycles, S(TV) and S(MV) showed significant decreases (P = 0.014 and P < 0.001, respectively) and D(TV) and D(MV) showed significant increases (P = 0.008 and P = 0.002, respectively) in fetuses with IUGR. CONCLUSION Time-interval alterations of DV-FVW in growth-restricted fetuses reflect the hemodynamic events caused by placental insufficiency.

Abstract
We report on the transmission experiment of seven 12.5-GHz spaced all optical-orthogonal frequency division multiplexed (AO-OFDM) subcarriers over a 35-km fiber link, using differential quadrature phase shift keying (DQPSK) modulation and direct detection. The system does not require chromatic dispersion compensation, optical time gating at the receiver (RX) or cyclic prefix (CP), achieving the maximum spectral efficiency. We use a wavelength selective switch (WSS) at the transmitter (TX) to allow subcarrier assignment flexibility and optimal filter shaping; an arrayed waveguide grating (AWG) AO-OFDM demultiplexer is used at the RX, to reduce the system cost and complexity.
